Description

Technical Field

[0001] This application relates to the field of digital printing technology, and in particular to a conveying component, a baking device, and a printing system. Background Technology

[0002] Direct-to-Film (DTF) printing involves directly printing images or designs onto a specialized film, which is then transferred to various textiles or other materials via heat transfer. The advantages of DTF printing include high precision, high color saturation, and excellent durability. Compared to traditional screen printing, DTF printing can achieve more complex patterns and colors, and is simpler to operate and more efficient. Furthermore, DTF printing is environmentally friendly and widely used in industries such as apparel, advertising, and gifts, providing designers and businesses with greater creative space and production flexibility.

[0003] The DTF printing process includes inkjet printing, application of hot melt adhesive powder, and baking. Currently, baking equipment generally uses conveyor rollers to transport the film material. In order to fix the film material on the conveyor rollers, the film material generally needs to have a long roll width. When users only need to print one or a few patterns, they still need to use film material with a long roll width, which wastes film material and greatly reduces printing efficiency. Utility Model Content

[0051] Figure 1 A schematic diagram of the printing system provided in this application.

[0052] Please see Figure 1This application provides a DTF printing system, which includes a printer 02 and a baking device 01. The printer 02 includes a printhead suitable for DTF printing. Exemplarily, the printhead can be an inkjet printhead, and the printer 02 can be an inkjet printer. The printer 02 is used to print a pattern onto a film material 100. The baking device 02 can be located on the discharge side of the printer 02, and can quickly receive the film material 100 after the printer 02 has printed the pattern. It is used to dry the pattern on the film material 100 after the printer 02 has printed the pattern, and to spread hot melt adhesive powder onto the film material 100 and melt the hot melt adhesive powder on the film material 100 through baking, so that the pattern on the film material 100 can be transferred to other objects (such as clothing, hats, etc.). The printing system can be a DTF printing system, etc., and is not specifically limited here.

[0053] Generally, PET film can be used for the film material 100. The thickness of the film material 100 can be 0.75mm. This material and thickness of film material 100 have good transferability, which can improve the clarity of the pattern transferred to the product. Single sheets can be used for small-scale DTF applications; PET film rolls can be used for large-scale DTF applications.

[0054] Figure 2 This is a first-view structural diagram of the baking equipment provided in this application.

[0055] like Figure 1 and Figure 2 As shown, the baking equipment 01 includes a housing 1. A feed port 11 is formed on the housing 1 to allow the film material 100 to pass through. The film material 100 with the printed pattern can enter the baking equipment 01 through the feed port 11 for powdering and baking operations.

[0056] Figure 3 for Figure 2 A cross-sectional view along the AA direction.

[0057] like Figure 3 As shown, in some embodiments, the housing 1 may include a frame 13 and side panels 14 fixed to the frame 13. The frame 13 forms a frame structure for supporting the baking equipment 01. The side panels 14 surround the outside of the frame 13, and a feed inlet 11 may be formed on the side panel 14 facing the printer 02 of the housing 1.

[0058] like Figure 2 and Figure 3 As shown, a receiving cavity is formed inside the outer shell 1. The baking equipment 01 also includes a buffer assembly 2, a powder-sprinkling assembly 3, a conveying assembly 4, and a baking assembly 5. The buffer assembly 2, the powder-sprinkling assembly 3, the conveying assembly 4, and the baking assembly 5 are respectively installed in the receiving cavity to improve the overall integrity of the baking equipment 01.

[0059] Specifically, the buffer assembly 2 is located between the feed inlet 11 and the conveying assembly 4 to guide the membrane material 100 entering from the feed inlet 11 to the conveying assembly 4. The conveying speed of the membrane material 100 can be buffered in the buffer assembly 2, thereby achieving tension isolation between the conveying and feeding of the membrane material 100, so that the two do not affect each other and improve the conveying effect of the membrane material 100.

[0060] The powder-spreading component 3 is located between the feed inlet 11 and the conveying component 4. The buffer component 2 is inserted into the powder-spreading component 3. The powder-spreading component 3 is used to collect hot melt adhesive powder and to spread the hot melt adhesive powder onto the membrane material 100. When the membrane material 100 is buffered in the buffer component 2, the powder-spreading component 3 can spread hot melt adhesive powder onto the membrane material 100 from above and recover excess hot melt adhesive powder.

[0061] The conveying assembly 4 is used to convey the membrane material 100, and the baking assembly 5 is located in the conveying path of the membrane material 100 to bake the membrane material 100 so that the hot melt adhesive powder melts onto the membrane material 100.

[0062] The above structure enables automated operation of film material 100 feeding, powdering, conveying and baking, improving the baking efficiency of film material 100 and enhancing the user experience.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the baking apparatus 01 has a length direction a, a height direction b, and a width direction c. The feed inlet 11 is located on one side of the outer casing 1 in the width direction c, and the powder-spreading assembly 3 extends along the height direction b and the length direction a. The buffer assembly 2 extends along the length direction a. The baking assembly 5 is located on one side of the powder-spreading assembly 3 in the width direction c, and is on the same side as the feed inlet 11 in the width direction c.

[0064] The positions of the various components of the baking equipment 01 are arranged in a reasonable manner, improving the compactness of the structure and reducing the volume of the baking equipment 01 without affecting its performance. By placing the baking component 5 on one side of the powder-spreading component 3 in the width direction c, the other side of the powder-spreading component 3 in the width direction c has space suitable for the extension of the conveying component 4. The baking component 5 is distributed on the same side as the feeding port 11 in the width direction c. Since the feeding end of the feeding port 11 faces the externally connected equipment, the baking component 5 is located on the side closer to the external equipment during use, avoiding discomfort to the operator caused by the heat generated by the baking component 5 during equipment operation, thus improving the user experience.

[0065] Furthermore, in some embodiments, an installation space 15 for mounting external devices is formed on the upper outer side of the outer shell 1. Inside the outer shell 1, a first receiving cavity 16 is formed parallel to the installation space 15 in the width direction c, and a second receiving cavity 17 is formed below the first receiving cavity 16 and the installation space 15 in the height direction b. A feed inlet 11 connects the first receiving cavity 16 and the installation space 15. A buffer assembly 2 is disposed in the first receiving cavity 16. A portion of the powder-spreading assembly 3 is disposed in the first receiving cavity 16, and another portion is disposed in the second receiving cavity 17. A baking assembly 5 is disposed in the second receiving cavity 17 and located below the installation space 15. In this way, external devices (such as printers) can be directly mounted on the installation space 15, saving installation area, shortening the transmission distance of the film material 100 from the external device to the baking equipment 01, and improving printing efficiency. The first receiving cavity 16 is arranged parallel to the installation space 15, and the buffer assembly 2 is disposed in the first receiving cavity 16, so that the film material 100 entering the baking equipment 01 from the external device through the feed inlet 11 can be directly transferred to the buffer assembly 2. The powder-sprinkling component 3 is partially located in the first receiving cavity 16 and partially in the second receiving cavity 17, making full use of the space in the height direction b and avoiding occupying a large space in the width direction c. The baking component 5 is located in the second receiving cavity 17 and below the installation space 15, further making full use of the space in the height direction b and the space in the width direction c, making the baking equipment 01 more compact in structure and smaller in size, and easier for users to operate.

[0066] Figure 4 This is a first-person view of the internal structure of the baking equipment provided in this application.

[0067] like Figure 3 and Figure 4 As shown, the baking equipment 01 also includes a receiving assembly 7, which is located at the bottom of the outer casing 1. The receiving assembly 7 forms a receiving cavity 711 and a receiving port 712, with the receiving port 712 connecting the receiving cavity 711 to the second receiving cavity 17. The receiving port 712 is opposite to the conveying assembly 4 located at the bottom of the baking assembly 5, so that the film material 100 on the conveying assembly 4 enters the receiving cavity 711 through the receiving port 712. The receiving assembly 7 provides storage space for the baked film material 100, allowing for immediate storage of the baked film material 100, reducing unnecessary waiting time and improving the user experience. The receiving assembly 7 is located on the other side of the powdering assembly 3 in the width direction c of the outer casing 1, which can effectively utilize the space of the second receiving cavity 17, optimize the internal layout of the equipment, and the receiving assembly 7 is located on different sides of the baking assembly 5 in the width direction c of the outer casing 1, so that the film material 100 can be removed from the receiving assembly 7 without having to approach the baking assembly 5, avoiding burns.

[0068] The receiving assembly 7 includes a receiving bin 71. The receiving bin 71 is connected to the housing 1 and located at the bottom of the housing 1, and is used to store the dried film material 100. The receiving bin 71 forms a receiving cavity 711 and a receiving port 712. The receiving bin 71 enables the automatic collection of the dried film material 100, thereby realizing the integrated automatic operation of the drying equipment.

[0069] The receiving bin 71 is detachably mounted on the housing 1 so that the receiving bin 71 can be removed.

[0070] The receiving assembly 7 may further include a guide 72, which is located at one end of the receiving bin 71 near the receiving port 712 to guide the film material 100 detached from the conveying assembly 4 into the receiving chamber 711. The guide 72 prevents the baked film material 100 from accumulating in the receiving bin 71 near the receiving port 712. For example, the guide 72 may be a component with a slope or curved surface (such as a ramp), or a fan, etc.

[0071] In this embodiment, the guide 72 is configured as a fan with the air outlet facing the receiving port 712. Multiple fans can be provided, and the multiple fans are distributed at intervals along the width of the film material 100 that has fallen off from the conveying assembly 4, so that the film material 100 can be subjected to a more uniform pushing force in the width direction, thereby being more neatly stored in the receiving bin 71.

[0072] The receiving assembly 7 may also include a fifth sensor (not shown in the figure). The fifth sensor may be disposed on the receiving hopper 71 or on the surface of the housing 1 opposite to the receiving hopper 71. The fifth sensor is used to detect the amount of film material 100 stored in the receiving hopper 71. When the amount of film material 100 stored in the receiving hopper 71 reaches a certain level, the fifth sensor can issue an alarm signal to remind the operator to remove the film material 100 from the receiving hopper 71. In one embodiment, the fifth sensor may be a photoelectric sensor or the like.

[0073] like Figure 4 As shown, the baking equipment 01 also includes a controller 9, which can be housed within the housing 1. In one embodiment, the controller 9 can be a PLC controller. The controller 9 is electrically connected to the buffer assembly 2, the powder-sprinkling assembly 3, the conveying assembly 4, and the baking assembly 5, respectively, to achieve centralized and unified control of the entire machine, thereby improving the accuracy of the automated control of the baking equipment 01.

[0074] The controller 9 may include a motherboard and electronic components and interfaces disposed on the motherboard. The motherboard may be fixed on the frame 13 or the side plate 14. In one embodiment, the motherboard may be disposed in the second receiving cavity 17 and located on the side of the powdering assembly 3 in the length direction a. In this way, the structural layout of the baking equipment 01 is more compact and makes full use of the space of the second receiving cavity 17.

[0075] Figure 5This is a schematic diagram of the internal structure of the baking equipment provided in this application from a second perspective. Figure 6 This is a schematic diagram of the powder-spraying component and the buffer component provided in this application. Figure 7 A schematic diagram of the structure of the buffer component provided in this application.

[0076] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the buffer assembly 2 includes a bracket 24, a swing member 21, and a second motor 22. The bracket 24 is fixed inside the housing 1 and serves as a support structure for the buffer assembly 2. The swing member 21 is swingably mounted on the bracket 24. The second motor 22 is disposed on the bracket 24 and is connected to the swing member 21 for driving the swing member 21 to swing.

[0077] The support 24 includes two mounting plates 241, which are arranged at intervals along the length direction a and are located on both sides of the conveying direction of the membrane material 100.

[0078] The swing member 21 can be swingably mounted on at least one mounting plate 241.

[0079] In some embodiments, the oscillating member 21 may be a grid-shaped plate structure. The oscillating member 21 has powder leakage holes 213, which can reduce the friction between the oscillating member 21 and the membrane material 100, and excess hot melt adhesive powder sprinkled downward by the powder dispensing component 3 or hot melt adhesive powder shaken off from the membrane material 100 can fall through the powder leakage holes 213 and be recycled.

[0080] The oscillating member 21 is positioned opposite the feed inlet 11. After the film material 100 enters the baking equipment 01 through the feed inlet 11, it is conveyed to the oscillating member 21. The oscillating member 21 is mounted on the support 24 and can oscillate relative to the support 24. The oscillating member 21 can oscillate within a range between a first position and a second position. The oscillating member 21 has a sloping feeding surface 211. When the oscillating member 21 is in the first position, both ends of the feeding surface 211 are close to the feed inlet 11 and the conveying assembly 4, respectively. When the oscillating member 21 is in the second position, there is a gap between the feeding surface 211 and the feed inlet 11. The first position can be the maximum height that the oscillating member 21 can reach when it oscillates upward, and the second position can be the zero position of the oscillation of the oscillating member 21. In other embodiments, the oscillating member 21 can also oscillate beyond the first position and the second position.

[0081] Specifically, in the initial state, the swing member 21 is in the second position. When the film material 100 enters the buffer assembly 2 from the feed port 11, the swing member 21 swings upward to the first position. The two ends of the swing member 21 can approach the feed port 11 and the conveying assembly 4 respectively. At this time, the film material 100 can pass through the feeding surface 211 of the swing member 21, be conveyed by the refrigerator conveying assembly 4, and fixed on the conveying assembly 4. After the film material 100 is fixed on the conveying assembly 4, the swing member 21 can swing downward to the second position. The conveying assembly 4 does not exert tension on the film material 100, and the film material 100 will be pressed down under the action of gravity to form an arc shape.

[0082] like Figure 7 As shown, the feeding surface 211 includes a first conveying sub-surface 2112 and a second conveying sub-surface 2111 connected together. Both the first conveying sub-surface 2112 and the second conveying sub-surface 2111 are curved surfaces. The first conveying sub-surface 2112 is closer to the feed inlet 11 than the second conveying sub-surface 2111. The tangent angle of the first conveying sub-surface 2112 gradually increases, while the tangent angle of the second conveying sub-surface 2111 gradually decreases. The first conveying sub-surface 2112 and the second conveying sub-surface 2111 form the aforementioned curved surfaces, which to a certain extent allows the membrane material 100 to pass more smoothly through the buffer assembly 2 to the conveying assembly 4.

[0083] like Figure 3 and Figure 6 As shown, the swing member 21 is disposed between two mounting plates 241 and can rotate relative to the mounting plates 241. The mounting plates 241 are provided with connecting holes, and one end of the swing member 21 is rotatably connected to the connecting hole on one of the mounting plates 241 via a shaft. The output shaft of the second motor 22 passes through the connecting hole on the other mounting plate 241 and is drively connected to the other end of the swing member 21, thereby realizing the rotation of the swing member 21. Furthermore, the second motor 22 is connected to one end of the swing member 21 along the conveying direction, enabling the swing member 21 to achieve a larger swing amplitude.

[0084] like Figure 3 As shown, the buffer assembly 2 includes a first sensor 27, which is located behind the swing member 21 along the conveying direction. The first sensor 27 is used to detect whether the film material 100 has reached the conveying assembly 4. When the first sensor 27 detects that the film material 100 is connected from the buffer assembly 2 to the conveying assembly 3, the second motor 22 controls the swing member 21 to swing downward to a second position, so that the film material 100 is buffered at the position of the buffer assembly 2, forming a downward curved arc, which prevents the film material 100 from piling up, thereby allowing the powder-spraying assembly 3 to evenly spray powder onto the film material 100.

[0085] The buffer assembly 2 includes a second sensor 23. The sensing direction of the second sensor 23 is towards the swing member 21, and it is used to detect the position of the swing member 21 and determine whether the swing member 21 has swung to the first position. In this embodiment, the second sensor 23 can be located on the side of the buffer assembly 2 facing the feed inlet 11. The distance between the second sensor 23 and the first position is relatively short, which improves the reaction speed of the second sensor 23.

[0086] When the swing member 21 swings to the first position, the second sensor 23 can generate an excitation signal, the second motor 22 stops rotating, and the membrane material 100 passes through the feeding surface 211 of the swing member 21 and enters the conveying assembly 4. At this time, whether the feeding surface 211 of the swing member 21 can contact the passing membrane material 100 and support the membrane material 100 so that the membrane material 100 can smoothly enter the conveying assembly 4.

[0087] like Figure 6 As shown, the buffer assembly 2 further includes a third sensor 26. The third sensor 26 is located below the first position and is used to detect whether the membrane material 100 sags to its lower limit position when the swing member 21 is in the second position, thereby controlling the conveying speed of the membrane material 100 in the conveying assembly 4. The third sensor 26 may be located on the outer casing 1.

[0088] In the above process, when the film material 100 is fixed to the conveying assembly 4, the second motor 22 rotates in the opposite direction, controlling the swinging component 21 to swing downwards. The transmission assembly 4 stops conveying the film material 100, and the film material 100 droops in the buffer assembly 2 under the pushing action of the printer, forming a downward-curving arc. When the film material 100 bends to a certain extent, the lower limit position of the film material 100 triggers the signal of the third sensor 26, and the conveying assembly 4 starts, conveying the film material 100 downstream. When the lower limit position of the film material 100 leaves the sensing range of the third sensor 26, the conveying assembly 4 stops working, and the film material 100 re-forms a downward-curving arc in the buffer assembly 2. This cycle repeats, realizing the automatic feeding of the film material 100.

[0089] In some embodiments, the first sensor 27, the second sensor 23, and the third sensor 26 may be photoelectric sensors or the like. The first sensor 27, the second sensor 23, and the third sensor 26 are each electrically connected to the controller 9.

[0090] In some embodiments, to further limit the movement of the swing member 21, at least one mounting plate 241 is provided with a limiting member 25. The limiting member 25 is disposed on the side of the mounting plate 241 facing the swing member 21, and protrudes from the surface of the mounting plate 241. The limiting member 25 can be used to limit the swing range of the swing member 21. When the swing member 21 swings upward to the first position, the limiting member 25 can abut against the swing member 21 to limit the swing member 21 from continuing to swing upward, ensuring that when the limiting member 25 swings upward, the membrane material 100 can be smoothly connected to the conveying assembly 4.

[0091] like Figure 3 and Figure 5 As shown, in some embodiments, the conveying component 4 is located downstream of the buffer component 2 and is used to convey the film material 100. It can convey the film material 100 from the buffer component 2 to the baking component 5, and can also convey the film material 100 to move relative to the baking component 5. The conveying component 4 can fix the two edges of the film material 100 along the conveying direction. The movement of the conveying component 4 can drive the film material 100 downstream, thus eliminating the need for traction by conveying rollers to convey the film material 100. This allows the conveying component 4 to convey short sheets of film material 100, improving the flexibility of the baking equipment 01 and reducing the waste of film material 100.

[0092] Figure 8 This is a first-view structural diagram of the transmission component provided in this application. Figure 9 This is a schematic diagram of the transmission component provided in this application from a second perspective. Figure 10 for Figure 9 Enlarged view of region C in the image.

[0093] like Figure 3 , Figure 5 , Figure 8 , Figure 9 and Figure 10 As shown, the conveying assembly 4 includes a drive sub-assembly 43 and a conveying sub-assembly 4a; the conveying sub-assembly 4a includes a conveyor belt 4a11, the conveyor belt 4a11 includes a belt body 4a111 and a first mating part 46, the belt body 4a111 is connected to the drive sub-assembly 43 to move under the drive of the drive sub-assembly 43, the first mating part 46 is provided on the outside of the belt body 4a111, and a second mating part (not shown in the figure) is provided on the membrane material 100. The first mating part 46 is used to cooperate with the second mating part on the membrane material 100 to fix the membrane material 100 on the conveyor belt 4a11.

[0094] The drive subassembly 43 includes a drive member 432 and a transmission member 431; the drive member 432 may be a motor. The transmission subassembly 4a includes a first transmission subassembly 41 and a second transmission subassembly 42. The drive member 432 is driveably connected to the transmission member 431, and the transmission member 431 is driveably connected to the first transmission subassembly 41 and the second transmission subassembly 42, so that the transmission member 431 can synchronously drive the first transmission subassembly 41 and the second transmission subassembly 42. The first transmission subassembly 41 and the second transmission subassembly 42 are at least partially arranged close to each other. Part of the first transmission subassembly 41 is located on the side of the powder-spreading assembly 3 away from the feed inlet 11, and part of the first transmission subassembly 41 is located below the powder-spreading assembly 3 in the height direction, so as to receive the film material 100 entering from the feed inlet 11, carry the film material 100 through the powder-spreading assembly 3, and then convey it to the baking assembly 5. The second transmission subassembly 42 surrounds at least part of the baking assembly 5, so that the hot melt adhesive powder on the film material 100 can be dried when the film material 100 passes through the baking assembly 5. During the process of conveying the membrane material 100 by the conveying component 4, the membrane material 100 can be transferred from the first conveying sub-component 41 to the second conveying sub-component 42 at a position where the first conveying sub-component 41 and the second conveying sub-component 42 are close to each other.

[0095] The transmission component 431 connects the first transmission sub-assembly 41 and the second transmission sub-assembly 42, reducing the need for a motor and simplifying the equipment structure. Furthermore, it improves the accuracy of the synchronous transmission between the first and second transmission sub-assemblies 41 and 42, thereby enhancing the stability of the film material 100 transmission. The first transmission sub-assembly 41 transports the film material 100 to the front of the baking assembly 5, while the second transmission sub-assembly 42 transports the film material 100 around the baking assembly 5, fully utilizing the baking area of ​​the baking assembly 5 for more thorough baking of the film material 100. Simultaneously, by rationally arranging the position of the first transmission sub-assembly 41, space is fully utilized, reducing the volume of the baking equipment 01.

[0096] Furthermore, in some embodiments, the first transmission sub-assembly 41 includes two first transmission modules 411 arranged opposite to and spaced apart along the width direction of the membrane material 100 and a first transmission member 412. The first transmission member 412 is connected to the two first transmission modules 411 in a transmission manner. In this way, the first transmission member 412 can realize the synchronous transmission of the two first transmission modules 411, and the two first transmission modules 411 can support both ends of the membrane material 100 in the width direction.

[0097] The lower part of the first conveying module 411 is inclined from front to back along the width direction of the outer shell 1, so that the lower part forms a space for setting the receiving component 7, and the receiving component 7 can be opened towards the front side of the outer shell 1, which facilitates the storage of the film material 100 after baking, and improves the compactness of the baking equipment 01 to a certain extent.

[0098] For example, the first conveying module 411 includes a first conveyor belt 4111 and a plurality of first drive wheels 4112, which can mesh with the plurality of first drive wheels 4112. The center points of the plurality of first drive wheels 4112 can be connected sequentially to form a polygon, and the plurality of first drive wheels 4112 can support the first conveyor belt 4111 and drive the first conveyor belt 4111 to move. The first transmission member 412 can extend along the length direction a and drively connect to one of the first drive wheels 4112 in the two first conveying modules 411. The first transmission member 412 can be a drive shaft, and the first drive wheels 4112 in the two first conveying modules 411 can be fixed at both ends of the drive shaft axially. One of the first drive wheels 4112 in one of the first conveying modules 411 can be connected to a transmission component 431 and move under the transmission of the transmission component 431.

[0099] In some embodiments, multiple first transmission wheels 4112 are respectively disposed at the inflection points of the first conveyor belt 4111, which can provide sufficient support for the first conveyor belt 4111 and avoid increasing the frictional force on the first conveyor belt 4111. The first transmission member 412 is disposed at the lower part of the first transmission sub-assembly 41, and the drive sub-assembly 43 is connected to the first transmission sub-assembly 41 and the second transmission sub-assembly 42 at the lower part of the conveying assembly 4. Because the drive sub-assembly 43 is relatively heavy, its placement at the lower part of the conveying assembly 4 can improve the stability of the baking equipment 01 to a certain extent.

[0100] Furthermore, in some embodiments, the second transmission sub-assembly 42 includes two second transmission modules 421 arranged opposite to and spaced apart along the width direction of the membrane material 100, and a second transmission member 422. The second transmission member 422 is drive-connected to the two second transmission modules 421, and the second transmission member 422 can realize synchronous transmission of the two second transmission modules 421, while the two second transmission modules 421 can support both ends of the membrane material 100 in the width direction.

[0101] For example, the second conveying module 421 includes a second conveyor belt 4211 and a plurality of second drive wheels 4212, which can mesh with the plurality of second drive wheels 4212. The center points of the plurality of second drive wheels 4212 can be connected sequentially to form a polygon, and the plurality of second drive wheels 4212 can support the second conveyor belt 4211 and drive the second conveyor belt 4211 to move. The second transmission member 422 can extend along the length direction a and drively connect one of the second drive wheels 4212 in the two second conveying modules 421. The second transmission member 422 can be a drive shaft, and the second drive wheels 4212 in the two second conveying modules 421 can be fixed at both ends of the drive shaft axially. One of the second drive wheels 4212 in one of the second conveying modules 421 can be connected to the transmission component 431 and move under the transmission of the transmission component 431.

[0102] The second conveyor belts 4211 of the two second conveyor modules 421 are respectively fixed on the two side walls along the length of the baking assembly 5. Specifically, the second drive wheels 4212 are located at the four corners of the two side walls along the length of the box 51 of the baking assembly 5, so that the second conveyor belts 4211 move in a circular loop.

[0103] In some embodiments, the first conveyor belt 4111 includes a belt body 4a111 and a first mating part 46. The second mating part is disposed on both sides of the membrane material 100 in the width direction. The first mating part 46 and the second mating part are mated together. In this way, the membrane material 100 can be fixed on the conveying assembly 4 by the connection between the first mating part 46 and the second mating part.

[0104] In some embodiments, the second conveyor belt 4211 includes a belt body 4a111 and a first mating part 46 to fix the membrane material 100 onto the second conveyor module 421, so that the second conveyor module 421 can drive the membrane material 100 to move.

[0105] Furthermore, the first mating portion 46 is provided on the side of the belt body 4a111 of the first conveyor belt 4111 facing the first limiting member 413, so that when the membrane material 100 is fixed on the first mating portion 46, it can be limited by the first limiting member 413. The first mating portion 46 is provided on the side of the belt body 4a111 of the second conveyor belt 4211 facing the second limiting member 423, so that when the membrane material 100 is fixed on the first mating portion 46, it can be limited by the second limiting member 423.

[0106] like Figure 5 , Figure 9 and Figure 10 As shown, in some embodiments, multiple first mating portions 46 are provided on the first conveyor belt 4111, and the multiple first mating portions 46 are equally spaced. Each first mating portion 46 includes a boss, and each second mating portion includes a through hole. Multiple second mating portions are equally spaced. The distance between two adjacent second mating portions is equal to the distance between two adjacent first mating portions 46. The through holes on the membrane material 100 can pass through the bosses to fix it to the conveying assembly 4. Multiple bosses are provided, and the multiple bosses are spaced apart along the length direction of the membrane material 100. A single membrane material 100 can be fixed on multiple bosses to improve the fit between the membrane material 100 and the conveying assembly 4. The equally spaced arrangement of multiple first mating portions 46 means that the membrane material 100 does not need to be fixed to a specific position on the first conveying module 411. Multiple first mating portions 46 can also be equally spaced on the second conveying module 421.

[0107] Furthermore, to facilitate the fitting of the membrane material 100 onto the boss, the diameter of the boss can be set to gradually decrease outward from the fixed position. For example, the boss can be conical. Alternatively, the top of the boss can be spherical, and the main body can be cylindrical.

[0108] The through-holes on the membrane material 100 can be configured as oblong holes, which further facilitates the fixing of the membrane material 100 to the boss. In other embodiments, the through-holes can also be round holes.

[0109] In other embodiments, the first mating part 46 may also be a hook or other structure, which will not be listed here.

[0110] like Figure 5 As shown, in some embodiments, the first conveying sub-assembly 41 further includes a first limiting member 413, which is disposed on the outside of the first conveying module 411 to restrict the membrane material 100 from detaching from the first conveying module 411. Exemplarily, the first limiting member 413 may be a guide rail, which may wrap around at least a portion of the first conveying module 411. A first mating portion 46 is formed on the side of the belt body 4a111 of the first conveyor belt 4111 facing the first limiting member 413. Thus, the membrane material 100 fixed on the first conveyor belt 4111 is difficult to detach from the first mating portion 46 on the first conveyor belt 4111 under the limitation of the first limiting member 413.

[0111] The second conveying sub-assembly 42 further includes a second limiting member 423, which is disposed on the outside of the second conveying module 421 to restrict the membrane material 100 from detaching from the second conveying module 421. For example, the second limiting member 423 may be a guide rail that can wrap around at least a portion of the second conveying module 421. A first mating portion 46 is formed on the side of the belt body 4a111 of the second conveyor belt 4211 facing the second limiting member 423. Thus, the membrane material 100 fixed to the second conveyor belt 4211 is difficult to detach from the first mating portion 46 on the second conveyor belt 4211 under the limiting of the second limiting member 423.

[0112] A first gap is formed between the first limiting member 413 and the first conveying module 411. The width of the first gap is adapted to the thickness of the film material 100. The film material 100 can move along the first gap, and it is ensured that the film material 100 will not detach from the first conveying module 411. A second gap is formed between the second limiting member 423 and the second conveying sub-assembly 42. The width of the second gap is adapted to the thickness of the film material 100. The film material 100 can move along the second gap, and it is ensured that the film material 100 will not detach from the second conveying sub-assembly 42.

[0113] Please see Figure 10The transfer assembly 4 also includes a first guide portion 45 disposed between the first transfer subassembly 41 and the second transfer subassembly 42. The first guide portion 45 is used to guide the membrane material 100 from the first transfer subassembly 41 to the second transfer subassembly 42 to realize the transfer of the membrane material 100.

[0114] The first conveyor assembly 41 and the second conveyor assembly 42 are close to each other on the side of the baking assembly 5 facing the powdering assembly 3, and the first guide portion 45 is formed in the area where the first conveyor assembly 41 and the second conveyor assembly 42 are close to each other.

[0115] The first guide portion 45 includes a second sub-guide portion 452. The second sub-guide portion 452 is formed on the side of the second limiting member 423 near the first transfer sub-assembly 41. The second sub-guide portion 452 has a second inclined surface facing the first transfer sub-assembly 41, which can guide the film material 100 from the first transfer module 411 to the second transfer module 421. The second limiting member 423 may abut against or be close to abut against the first transfer module 411, and the second sub-guide portion 452 is formed on the portion of the second limiting member 423 that abuts against or is opposite to the first transfer module 411.

[0116] In this configuration, the first conveying module 411 and the second conveying module 421 rotate in opposite directions. For example, the first conveying module 411 rotates clockwise to convey the membrane material 100 to a position close to the second conveying module 421, while the second conveying module 421 rotates counterclockwise. Thus, under the rotation of the first and second conveying modules 411 and 421, and with the action of the second sub-guide portion 452, the membrane material 100 can be transferred from the first conveying module 411 to the second conveying module 421 when the first and second conveying modules 411 are close to each other.

[0117] In some embodiments, the first guide portion 45 further includes a first sub-guide portion 451. The first sub-guide portion 451 is located on the side of the first limiting member 413 near the second transfer sub-assembly 42, and the first sub-guide portion 451 is offset from the second sub-guide portion 452. The first sub-guide portion 451 has a first inclined surface extending toward the second transfer sub-assembly 42, which can guide the film material 100 to gradually detach from the first transfer module 411.

[0118] The transmission sub-assembly 4a is configured as the first transmission sub-assembly 41 and the second transmission sub-assembly 42. This can optimize the transmission direction of the transmission assembly 4 within a limited space, reduce the frequency of changes in the transmission angle of a single transmission sub-assembly 4a, improve the stability of the membrane material 100 transmission, facilitate the layout of each component, and improve the compactness of the overall structure, thereby reducing the overall size of the machine.

[0119] In some embodiments, the first limiting member 413 is further provided with a second guide portion 4131 at one end near the buffer assembly 2. The second guide portion 4131 can be bent upward to guide the membrane material 100 entering the conveying assembly 4, so that the membrane material 100 entering the second guide portion 4131 can gradually approach the first transmission member 412, thereby connecting to the conveying assembly 4 and moving with the conveying assembly 4. The second guide portion 4131 may have a guide surface or a guide slope, and the tangent angle of the guide surface may gradually decrease.

[0120] In some embodiments, the first sensor 27 may be disposed at the second guide portion 4131 to detect whether the film material 100 enters the conveying assembly 4 from the buffer assembly 2. When the first sensor 27 detects that the film material 100 is connected from the buffer assembly 2 to the conveying assembly 4, the second motor 22 controls the swing member 21 to swing downward to the zero position, so that the film material 100 forms a downward curved arc at the position of the buffer assembly 2, which facilitates the powder-spraying assembly 3 to spray powder onto the film material 100.

[0121] like Figure 5 and Figure 8 As shown, in some embodiments, the transmission component 431 includes a first gear 4311, a second gear 4312, and a third gear 4313. The first gear 4311 is disposed between the second gear 4312 and the third gear 4313, and meshes with both the second gear 4312 and the third gear 4313. The first gear 4311 is also connected to one of the first transmission modules 411 in the first transmission sub-assembly 41, thereby driving the first transmission module 411 to rotate synchronously. The rotation direction of the first gear 4311 is the same as that of the first transmission module 411, causing the first transmission module 411 to gradually move the membrane material 100 closer to the second transmission sub-assembly 42. The second gear 4312 is connected to one of the second transmission modules 421 in the second transmission sub-assembly 42, thereby driving the second transmission module 421 to rotate synchronously. The third gear 4313 is connected to the driving component 432. In the above, the transmission component 431 is used to improve the accuracy of the transmission, and at the same time, it is not necessary to set up multiple motors to drive the first transmission sub-component 41 and the second transmission sub-component 42 respectively.

[0122] like Figure 5 and Figure 8 As shown, in other embodiments, the transmission component 4 includes a code disk 47 and a sixth sensor 48. The code disk 47 is connected to the first transmission sub-component 41 and the second transmission sub-component 42 via a transmission component 431.

[0123] Specifically, the code disk 47 is coaxially arranged with the first gear 4311. The code disk 47 has a circumferential code track, which is divided into multiple areas of equal size. The time it takes for the code disk 47 to rotate through each area on the code track is equal to the transmission time required to travel the distance between two adjacent second mating parts on the membrane material 100. The rotation trajectory of the code disk 47 is within the detection range of the sixth sensor 48, which is used to detect the rotation distance of the code disk 47.

[0124] The first gear 4311, the second gear 4312, and the third gear 4313 have the same radius of rotation. A sixth sensor 48 is located on one side of the code disk 47 and is used to detect the rotation distance of the code disk 47. When the code track of the code disk 47 passes the sixth sensor 48, the sixth sensor 48 generates an excitation signal. Each area on the code track can correspond to multiple first mating parts 46. By detecting the position of the code track on the code disk 47 by the sixth sensor 48, it is determined whether the first mating parts 46 have moved to the engagement position, thereby controlling the transmission of the membrane material 100 and engaging the second mating parts on the membrane material 100 with the first mating parts 46 to accurately fix it to the first transmission sub-assembly 41.

[0125] In some embodiments, the sixth sensor 48 may be a photoelectric sensor or the like.

[0126] Figure 11 for Figure 3 Enlarged view of region B in the image.

[0127] like Figure 3 , Figure 5 and Figure 11 As shown, the powder application assembly 3 includes a powder application mechanism 31, a powder storage mechanism 32, and a powder circulation mechanism 33. The powder application mechanism 31 is positioned above the buffer assembly 2 and is used to apply hot melt adhesive powder to the film material 100 located on the buffer assembly 2. When the swing member 21 swings downward to the second position, the film material 100 forms a downward-curved arc. At this time, the powder application mechanism 31 applies hot melt adhesive powder to the film material 100, enabling the hot melt adhesive powder to be more evenly distributed on the surface of the film material 100 and better covering the pattern.

[0128] The powder storage mechanism 32 is used to store hot melt adhesive powder. The powder storage mechanism 32 is located below the powder dispensing mechanism 31, and the powder storage mechanism 32 has a powder recovery port 3215 facing the powder dispensing mechanism 31.

[0129] The powder circulation mechanism 33 is at least partially disposed in the powder storage mechanism 32 and is opposite to the powder dispensing mechanism 31. It is used to circulate between the powder dispensing mechanism 31 and the powder storage mechanism 32, and to carry out a portion of the hot melt adhesive powder in the powder storage mechanism 32 and transfer at least a portion of the hot melt adhesive powder to the powder dispensing mechanism 31.

[0130] Figure 12 This is a schematic diagram of the powder-spreading mechanism provided in this application.

[0131] like Figure 3 , Figure 11 and Figure 12 As shown, the powder-spreading mechanism 31 further includes a powder-spreading bin 311, a powder-spreading roller 313, and a third motor 314. The powder-spreading bin 311 is disposed above the buffer assembly 2, and both ends of the powder-spreading bin 311 are fixed to the bracket 24. The powder-spreading roller 313 is disposed in the powder-spreading nozzle and extends along the length of the powder-spreading nozzle. One end of the powder-spreading roller 313 is rotatably connected to one of the mounting plates 241. The output shaft of the third motor 314 passes through another mounting plate 241 and is drively connected to the other end of the powder-spreading roller 313 to drive the powder-spreading roller 313 to rotate, so as to carry the hot melt adhesive powder in the powder-spreading bin 311 out of the powder-spreading nozzle and spread it downward onto the film material 100.

[0132] The powder dispensing bin 311 stores the hot melt adhesive powder transferred from the powder storage mechanism 32 by the powder circulation mechanism 33. The inner diameter of the powder dispensing bin 311 gradually decreases from top to bottom, and its cross-section is approximately V-shaped, allowing the hot melt adhesive powder in the powder dispensing bin 311 to slide more effectively to the bottom of the powder dispensing bin 311. A powder dispensing port is provided at the bottom of the powder dispensing bin 311 to facilitate the discharge of hot melt adhesive powder from the port. The powder dispensing port extends along the length of the powder dispensing bin 311. It is understood that the length of the powder dispensing port is not less than the width of the film material 100 to ensure that the hot melt adhesive powder can cover all positions along the width of the film material 100.

[0133] To improve the strength of the powder spreading chamber 311, multiple reinforcing ribs 3111 are distributed at intervals inside the powder spreading chamber 311. The reinforcing ribs 3111 are connected to the two side walls along the length of the powder spreading chamber 311.

[0134] In some embodiments, the powder application mechanism 31 is linked to the printer 02. After the film material 100 reaches a specific position, it controls the third motor 314 to rotate for a certain period of time to ensure that a sufficient amount of hot melt adhesive powder is applied. Then, the third motor 314 stops rotating, precisely controlling the landing point of the hot melt adhesive powder on the film material 100. The amount of powder applied can be adjusted by printing parameters, such as increasing the amount of powder applied for higher pass counts or larger images.

[0135] Figure 13 This is a schematic diagram of the powder-spreading roller provided in this application.

[0136] like Figure 12 and Figure 13As shown, the powder-spreading roller 313 is disposed in the powder-spreading nozzle and extends along the length of the nozzle. A third motor 314 is connected to the powder-spreading roller 313 for driving the roller to rotate, thereby dispensing the hot melt adhesive powder from the powder-spreading chamber 311 through the nozzle and spreading it downwards onto the film material 100. The surface of the powder-spreading roller 313 is provided with at least one powder groove 3131, which can be used to hold the hot melt adhesive powder. The powder groove 3131 extends axially along the powder-spreading roller 313. When the roller rotates, the powder groove 3131 can carry out the hot melt adhesive powder from the powder-spreading chamber 311, thus dispensing the hot melt adhesive powder through the nozzle and improving the uniformity of the hot melt adhesive powder distribution on the film material 100.

[0137] like Figure 13 As shown, in some embodiments, the powder-spreading roller 313 has multiple powder grooves 3131 on its circumferential surface. The multiple powder grooves 3131 are evenly distributed at intervals along the circumference to improve the powder-spreading efficiency.

[0138] like Figure 11 and Figure 12 As shown, in some embodiments, the powder dispensing mechanism 31 further includes a powder scraper 315. The powder scraper 315 is disposed in the area of ​​the powder dispensing chamber 315 near the powder dispensing port. The powder scraper 315 is in contact with the powder dispensing roller 313 so as to scrape the hot melt adhesive powder in the powder trough 3131 into the powder dispensing port when the powder dispensing roller 313 rotates.

[0139] In some embodiments, two powder scrapers 315 are provided, with the two powder scrapers 315 respectively disposed at both ends of the powder dispensing nozzle, and the two powder scrapers 315 facing opposite directions and located on both sides of the powder dispensing roller 313 in the radial direction, and both abutting against the powder dispensing roller 313.

[0140] Two powder scrapers 313 are located on both sides of the powder spreading roller 313 along its axial direction, and the distance between the two powder scrapers 315 is no greater than the width of the powder spreading roller 313. When the powder spreading roller 313 rotates, the two powder scrapers 315 can sweep the hot melt adhesive powder on the powder trough 3131, so that the hot melt adhesive powder can fall onto the film material 100.

[0141] Two powder scrapers 315 are inclined and face opposite directions, with the inclination direction opposite to the rotation direction of the powder-spreading roller 313. This allows the two powder scrapers 315 to insert into the powder trough 3131 when the powder-spreading roller 313 rotates, and to effectively carry out the hot melt adhesive powder from the powder trough 3131 in the opposite direction of the rotation of the powder-spreading roller 313. For example, when the powder-spreading roller 313 rotates counterclockwise, one powder scraper 315 is located in front of the powder-spreading roller 313 and is inclined downwards; the other powder scraper 316 is located behind the powder-spreading roller 313 and is inclined upwards.

[0142] In some embodiments, the powder scraper 315 is a brush, which includes a soft portion that contacts the powder-spreading roller 313. This soft portion can deform as the powder-spreading roller 313 rotates, thereby scraping off the hot melt adhesive powder in the powder trough 3131. In other embodiments, the powder scraper 315 can also be a component made of other soft materials, such as a silicone strip.

[0143] Figure 14 This is a schematic diagram of the powder-spraying component provided in this application.

[0144] like Figure 3 , Figure 6 and Figure 14 As shown, the powder storage mechanism 32 has a communicating powder recovery chamber 321a1. The powder recovery chamber 321a1 is closer to the powder spreading mechanism 31 than the powder storage chamber 321b1. The powder spreading mechanism 31 is correspondingly disposed above the powder recovery chamber 321a1. The buffer assembly 2 is at least partially disposed in the powder recovery chamber 321a1 and can swing within the powder recovery chamber 321a1. The powder dispensing mechanism 31 is positioned above the powder recovery chamber 321a1. The buffer component 2 is at least partially located within the powder recovery chamber 321a1 and can swing within it. This allows excess powder to enter the powder recovery chamber 321a1 when the powder dispensing component 3 spreads hot melt adhesive powder onto the film material 100. The powder recovery chamber 321a1 is connected to the powder storage chamber 321b1, allowing the hot melt adhesive powder collected in the powder recovery chamber 321a1 to fall directly into the powder storage chamber 321b1, eliminating the need for frequent cleaning and improving the user experience.

[0145] The powder storage mechanism 32 includes a powder storage bin 321 and a powder filling bin 322. The powder storage bin 321 is located below the buffer assembly 2, and the powder filling bin 322 is inserted through the upper part of the powder storage bin 321 and can rotate along the powder storage bin 321 and can be pulled out from the powder storage bin 321 for powder filling operation.

[0146] The powder storage hopper 321 can be used to store hot melt adhesive powder. A powder recovery chamber 321a1 and a powder storage chamber 321b1 are formed in the powder storage hopper 321. The powder storage hopper 321 has an upward-facing powder recovery port 3215, which connects the powder recovery chamber 321a1 and the first receiving chamber 16. Excess hot melt adhesive powder on the film material 100 or hot melt adhesive powder falling from the powder spreading mechanism 31 can be recovered from the powder recovery port 3215 into the powder storage hopper 321, which facilitates the recycling of hot melt adhesive powder.

[0147] The upper part of the powder storage bin 321 is V-shaped, that is, the upper cross section of the powder storage bin 321 gradually increases from bottom to top. This not only ensures that the powder recovery port 3215 is large enough to receive the hot melt adhesive powder falling from the powder spreading mechanism 31, but also allows the recovered hot melt adhesive powder to slide quickly down the inclined side wall of the powder storage bin 321 to the bottom of the powder storage bin 321.

[0148] The powder storage hopper 321 includes a powder recovery section 321a and a powder storage section 321b. The powder recovery section 321a is located above the powder storage section 321b, and a powder recovery port 3215 is formed at the upper end of the powder recovery section 321a. The width of at least a portion of the powder recovery section 321a and at least a portion of the powder storage section 321b gradually decreases from top to bottom. This allows for easier transfer of hot melt adhesive powder even when the volume is small. A powder recovery cavity 321a1 is formed in the powder recovery section 321a; a powder storage cavity 321b1 is formed in the powder storage section 321b.

[0149] Furthermore, a grid 325 is provided inside the powder storage bin 321 near the powder recovery port 3215. By providing the grid 325, it is possible to prevent the hot melt adhesive powder in the powder storage bin 321 from being carried away by the airflow generated by the swinging of the swinging component 21 when there is a lot of hot melt adhesive powder in the powder storage bin 321.

[0150] The powder filling hopper 322 has a powder discharge port, through which the hot melt adhesive powder in the powder filling hopper 322 can be poured into the powder storage hopper 321.

[0151] Figure 15 This is a structural schematic diagram of the baking equipment provided in this application from a second perspective.

[0152] like Figure 3 and Figure 15 As shown, a first through hole 3214 is formed on one side wall of the powder storage bin 321, and the powder adding bin 322 is inserted through the first through hole 3214.

[0153] Figure 16 This is a schematic diagram of the internal structure of the powder-spraying component provided in this application. Figure 17 This is a structural schematic diagram of the powder-spraying component provided in this application from a second perspective. Figure 18 for Figure 17 A sectional view along the EE direction.

[0154] like Figures 16 to 18 As shown, a third limiting protrusion 3222 is formed on the side wall of the powder filling chamber 322, and the protruding direction of the third limiting protrusion 3222 is consistent with the orientation of the powder discharge port of the powder filling chamber 322. A first notch 32141 is formed on the upper part of the first through hole 3214, and the third limiting protrusion 3222 is adapted to the first notch 32141.

[0155] A first limiting protrusion 3212 and a second limiting protrusion 3213 are formed on the inner wall of the powder storage bin 321 near the first through hole 3214. The first limiting protrusion 3212 is located at the upper part of the first through hole 3214, and the second limiting protrusion 3213 is located at the lower part of the first through hole 3214. The powder filling bin 322 has a first position and a second position relative to the powder storage bin 321. When the powder filling bin 322 is in the first position, the first notch 32141 is correspondingly set with the third limiting protrusion 3222, and the third limiting protrusion 3222 abuts against the first limiting protrusion 3212. When the powder filling bin 322 rotates until the third limiting protrusion 3222 abuts against the first limiting protrusion 3212, the opening of the powder filling groove 3221 faces the same direction, and the powder filling bin 322 can be pushed out of the powder storage bin 321. When the powder filling hopper 322 is in the second position, the third limiting protrusion 3222 abuts against the second limiting protrusion 3213. At this time, the powder discharge port of the powder filling hopper 322 faces downward, and the hot melt adhesive powder in the powder filling hopper 322 can be transferred to the powder storage hopper 321.

[0156] In some embodiments, the first limiting protrusion 3212 and the second limiting protrusion 3213 are disposed at both ends radially of the first through hole 3214, and the second limiting protrusion 3213 limits the third limiting protrusion 3222 to the bottom of the first through hole 3214. Thus, when the powder filling hopper 322 pours hot melt adhesive powder into the powder storage hopper 321, the powder discharge port of the powder filling hopper 322 faces downwards, ensuring that the hot melt adhesive powder in the powder filling hopper 322 can completely fall into the powder storage hopper 321.

[0157] When adding hot melt adhesive powder, rotate the powder filling hopper 322 until the third limiting protrusion 3222 abuts against the first limiting protrusion 3212, pull out the powder filling hopper 322, add hot melt adhesive powder into the powder filling hopper 322, then insert the powder filling hopper 322 into the powder storage hopper 321, and rotate the powder filling hopper 322 to pour the hot melt adhesive powder in the powder filling hopper 322 into the powder storage hopper 321. Repeat this operation until the powder filling operation is completed.

[0158] A sleeve 3216 is also provided inside the powder storage bin 321. The sleeve 3216 can rotate relative to the powder storage bin 321, and the sleeve 3216 abuts against the lower outer side of the powder filling bin 322, which can support the powder filling bin 322 and can rotate relative to it to make the powder filling bin 322 rotate more smoothly.

[0159] A fourth sensor 323 is installed inside the powder storage hopper 321. The fourth sensor 323 can detect the volume of hot melt adhesive powder in the powder storage hopper 321. When the volume of hot melt adhesive powder in the powder storage hopper 321 falls below a certain level, the fourth sensor 323 will issue an alarm to prompt the addition of powder.

[0160] Furthermore, multiple fourth sensors 323 can be installed at different heights within the powder storage bin 321 to generate different powder addition signals.

[0161] like Figure 15 As shown, furthermore, a powder filling port 12 is formed on the outer shell 1, and the powder filling port 12 and the powder filling chamber 322 are arranged opposite to each other for removing the powder filling chamber 322. The powder filling port 12 is covered by an oil and powder filling cover 6 to seal the powder filling port 12 and prevent accidental contact with the powder filling chamber 322.

[0162] The powder filling cover 6 can be movably connected to the outer shell 1, or one side of the powder filling cover 6 can be rotatably connected to the outer shell 1 through a connector. A rebound member 324 is provided on the outer wall of the powder storage chamber 321. The other side of the powder filling cover 6 can be connected to the powder storage chamber 321 through the rebound member 324, so as to facilitate the opening and closing of the powder filling cover 6 and the removal and placement of the powder filling chamber 322.

[0163] In this embodiment, the powder adding hopper 322 can add 2kg of hot melt adhesive powder at a time, and the powder storage hopper 321 can hold 4kg of hot melt adhesive powder. The powder storage hopper 321 has a large capacity, which can reduce the frequency of powder adding.

[0164] like Figure 3 and Figure 6 As shown, the powder circulation mechanism 33 includes a powder circulation timing belt 331, a transmission structure 335, and a fourth motor 332. The powder circulation timing belt 331 forms a circulation loop between the powder spreading mechanism 31 and the powder storage mechanism 32. Part of the powder circulation timing belt 331 is located above the powder spreading mechanism 31, and part of the powder circulation timing belt 331 is located in the powder storage mechanism 32. The powder circulation timing belt 331 is used to carry out part of the hot melt adhesive powder in the powder storage mechanism 32 for transfer to the powder spreading assembly 3.

[0165] The powder circulation synchronous belt 331 includes a body 3312 and a plurality of protrusions 3311 disposed on the outside of the body 3312. The inner side of the body 3312 is connected to the transmission structure 335 for transmission. The plurality of protrusions 3311 are spaced apart, and a powder space is formed between two adjacent protrusions 3311. The powder space is used to carry hot melt adhesive powder.

[0166] The portion of the powder circulation synchronous belt 331 located within the powder storage mechanism 32 extends to the bottom of the powder storage bin 321. The bottom of the powder storage bin 321 forms a trough through which the powder circulation synchronous belt 331 passes. During the circulation movement of the powder circulation synchronous belt 331, the protrusion 3311 carries the hot melt adhesive powder in the powder storage bin 321 along the trough inside the powder storage bin 321 and rises to the powder spreading bin 311.

[0167] like Figure 6 and Figure 16 As shown, a powder guide groove 3211 is provided on one side of the powder storage bin 321. The powder guide groove 3211 extends along the height direction of the powder storage bin 321. The powder circulation synchronous belt 331 is provided in the powder guide groove 3211, which drives the hot melt adhesive powder from the powder storage bin 321 to the powder spreading bin 311.

[0168] The transmission structure 335 includes a driving wheel 3351 and multiple driven wheels 3352. The driving wheel 3351 and the driven wheels 3352 are respectively located on the transmission path of the powder circulation synchronous belt 331. Both the driving wheel 3351 and the driven wheels 3352 are connected to the powder circulation synchronous belt 331 for transmission. The driven wheels 3352 are used to change the transmission direction of the powder circulation synchronous belt 331.

[0169] The fourth motor 332 is connected to the powder circulation synchronous belt 331 for driving the powder circulation synchronous belt 331 to move cyclically along the powder spreading mechanism 31 and the powder storage mechanism 32, so as to transfer the hot melt adhesive powder in the powder storage mechanism 32 to the powder spreading mechanism 31, thereby realizing the spreading, recycling and reuse of hot melt adhesive powder.

[0170] like Figure 6 As shown, the powder circulation mechanism 33 also includes a powder unloading component 334. The powder unloading component 334 is disposed above the powder dispensing bin 311 of the powder dispensing mechanism 31 and located outside the powder circulation synchronous belt 311, and at least one is provided along the length direction of the powder dispensing bin 311. The powder unloading component 334 is used to unload the hot melt adhesive powder carried on the powder circulation synchronous belt 331 during the movement of the powder circulation synchronous belt 331, so that the hot melt adhesive powder falls into the powder dispensing bin 311. The powder unloading component 334 can contact the powder circulation mechanism 33 and scrape off the powder on the powder circulation mechanism 33.

[0171] Since the powder circulation mechanism 33 continuously circulates, the powder unloading component 334 is located in the circulation path of the powder circulation mechanism 33 and can cover most of the position of the powder circulation mechanism 33 in the powder dispensing chamber 311. This allows the hot melt adhesive powder to be transferred more evenly into the powder dispensing chamber 311, thereby improving the uniformity of hot melt adhesive powder adhesion on the film material 100. Preferably, multiple powder unloading components 334 are spaced apart along the length of the powder dispensing chamber 311. This not only allows the hot melt adhesive powder to be transferred more evenly into the powder dispensing chamber 311 but also reduces the friction between the powder unloading component 334 and the powder circulation mechanism 33.

[0172] In some embodiments, the powder unloading component 334 may not be provided. Alternatively, the hot melt adhesive powder on the powder circulation mechanism 33 may be dropped into the powder spreading bin 311 by shaking the portion of the powder circulation mechanism 33 within the powder spreading bin 311. Specifically, a motor drive may be used to shake the powder circulation mechanism 33, or a structure with varying heights may be provided within the powder spreading bin 311 so that the powder circulation mechanism 33 shakes when it moves to that structure.

[0173] like Figure 16As shown, to ensure the normal operation of the powder circulation synchronous belt 331, the powder circulation mechanism 33 also includes a tensioning mechanism 333. The tensioning mechanism 333 is disposed in the powder storage mechanism 32 and located in the conveying path of the powder circulation synchronous belt 331, through which the powder circulation synchronous belt 331 passes. The tensioning mechanism 333 can move in a direction away from the powder circulation synchronous belt 331 to adjust the tension of the powder circulation synchronous belt 331.

[0174] In some embodiments, the tensioning mechanism 333 includes a tensioning element 3331 and a tensioning screw 3332. The tensioning element 3331 is disposed in the powder storage bin 321, and the powder circulation synchronous belt 331 passes through the tensioning element 3331 and is rotatably connected to one of the driven wheels 3352 of the powder circulation mechanism 33. One end of the tensioning screw 3332 passes through a side wall of the powder storage bin 321 and is connected to the tensioning element 3331. By adjusting the length of the tensioning screw 3332 screwed into the powder storage bin 321, the tension of the powder circulation synchronous belt 331 can be adjusted to ensure the normal operation of the powder circulation synchronous belt 331.

[0175] Specifically, the tensioning member 3331 is U-shaped and has an opening facing the powder circulation timing belt 331. One of the driven wheels 3352 of the powder circulation mechanism 33 is fixed to the open end of the tensioning member 3331 via a shaft, and the tensioning screw 3332 is fixed to the end opposite the opening. The powder storage bin 321 is provided with a waist-shaped hole that extends along the moving direction of the tensioning screw 3332 and corresponds to the tensioning member 3331. The tensioning member 3331 is slidably connected to the waist-shaped hole via a connector, so that when the tensioning screw 3332 is rotated, the tensioning member 3331 can slide along the waist-shaped hole to adjust the tension of the powder circulation timing belt 331.

[0176] like Figure 14 and Figure 16 As shown, the powder application assembly 3 also includes a powder tapping mechanism 34. The powder tapping mechanism 34 is disposed between the powder application mechanism 31 and the powder storage mechanism 32, and is located in the conveying path of the membrane material 100. Located downstream of the powder application mechanism 31, the powder tapping mechanism 34 can intermittently tap the membrane material 100 after the hot melt adhesive powder has been applied, shaking off any unadhered hot melt adhesive powder from the membrane material 100. By tapping the membrane material 100 after powder application using the powder tapping mechanism 34, the uniformity of the hot melt adhesive powder on the membrane material 100 can be improved.

[0177] The powder-tapping mechanism 34 includes a fifth motor 341, a rotating shaft 342, and at least one tapping element 343 disposed on the rotating shaft 342. One end of the rotating shaft 342 is rotatably mounted on a bracket 24, and the fifth motor 341 is fixedly mounted on the bracket 24. The fifth motor 341 is drively connected to the other end of the rotating shaft 342 to drive the rotating shaft 342 to rotate. The tapping element 343 is disposed on the rotating shaft 342 and extends radially along the rotating shaft 342. When the rotating shaft 342 rotates, the tapping element 343 can rotate to the back side of the membrane material 100 located in the buffer assembly 2 and contact the back side of the membrane material 100 to tap the membrane material 100. This shakes off excess hot melt adhesive powder from the membrane material 100, improving the utilization rate of the hot melt adhesive powder.

[0178] When the powder-tapping mechanism 34 is in operation, the fifth motor 341 rotates in both the forward and reverse directions in a cycle, so that the tapping component 343 can produce intermittent tapping action on the membrane material 100.

[0179] The fifth motor 341 can be linked with the printer 02. The second sensor 23 and the third sensor 26 estimate the conveying position of the film material 100. When the film material 100 arrives, the powder is shaken off. After the film material 100 has completely entered the baking equipment 01, the powder-shaking mechanism 34 stops operating.

[0180] In some embodiments, multiple tapping elements 343 are provided, and the multiple tapping elements 343 are distributed at intervals along the axial direction of the rotation axis 342 to cover a wider area of ​​the membrane material 100 and more effectively shake off excess hot melt adhesive powder on the membrane material 100.

[0181] like Figure 14 As shown, the powder-tapping mechanism 34 is located on the side of the buffer assembly 2 facing away from the feed inlet 11 and is fixed below the buffer assembly 2. A clearance groove 214 is provided at the end of the swing member 21 facing away from the feed inlet 11. The opening of the clearance groove 214 faces the conveying direction of the film material 100. Multiple clearance grooves 214 are spaced apart along the length of the swing member 21 in the baking equipment 01. The clearance grooves 214 correspond to the tapping member 343. The powder-tapping mechanism 34 can rotate until the tapping member 343 inserts into the clearance groove 214, and can tap the back of the film material 100 located in the buffer assembly 2 to shake off any unadhered hot melt adhesive powder from the film material 100. This results in a more compact structural layout, which is beneficial for miniaturization.

[0182] like Figure 14As shown, the tapping component 343 includes a clamping body 3431 and a flexible component 3432 fixed to the end of the clamping body 3431. The clamping body 3431 is fixed to the rotating shaft 342. The flexible component 3432 can be disposed at one end of the clamping body 3431 or at both ends of the clamping body 3431. For example, the flexible component 3432 can be made of silicone, which has a certain strength and can not only produce an effective tapping effect on the membrane material 100, but also will not scratch the membrane material 100.

[0183] Figure 19 This is a schematic diagram of the baking assembly provided in this application. Figure 20 for Figure 19 A cross-sectional view along the DD direction.

[0184] like Figure 3 , Figure 19 and Figure 20 As shown, the baking assembly 5 includes a housing 51, a heating element 52, and an exhaust structure 53. An air inlet 511 is formed at the bottom of the housing 51. The conveying assembly 4 surrounds at least a portion of the housing 51, and the at least a portion of the housing 51 includes at least two surfaces. At least one heating element 52 is disposed within the housing 51 and is used to generate heat. The exhaust structure 53 communicates with the interior of the housing 51 and can be connected to an external exhaust gas purification device to drive airflow within the housing 51, thereby discharging the exhaust gas generated within the housing 51 to the external exhaust gas purification device.

[0185] When the membrane material 100 passes through the baking assembly 5, the membrane material 100 moves between the chamber 51 and the heating element 52, and the membrane material 100 is conveyed along at least three heating surfaces parallel to the chamber 51 in sequence, so that the membrane material 100 travels a longer distance through the baking assembly 5, thereby improving the drying effect.

[0186] like Figure 3 and Figure 8 As shown, the exhaust structure 53 further includes an exhaust fan 531, a first exhaust pipe 532, and a second exhaust pipe 533. The exhaust fan 531 is located at the top of the housing 51 and communicates with the interior of the housing 51. The exhaust fan 531 includes an air inlet and an air outlet, with the air inlet communicating with the interior of the housing 51. The first exhaust pipe 532 and the second exhaust pipe 533 are respectively inserted through the housing 51. One end of the first exhaust pipe 532 communicates with the air outlet of the exhaust fan 531, and one end of the second exhaust pipe 533 communicates with the other end of the first exhaust pipe 532. The other end of the second exhaust pipe 533 is also connected to an external exhaust gas purification device. The inner diameter of the first exhaust pipe 532 is smaller than the inner diameter of the second exhaust pipe 533, resulting in a Bernoulli fluid within the exhaust structure 53, thereby increasing the emission velocity of the exhaust gas within the housing 51.

[0187] Furthermore, the first exhaust pipe 532 and the second exhaust pipe 533 are axially connected and connected inside the housing 51. The non-connecting ends of the first exhaust pipe 532 and the second exhaust pipe 533 are respectively installed on the opposite side walls of the housing 51, which improves the compactness of the baking equipment 01 to a certain extent and reduces the volume of the baking equipment 01.

[0188] At least one heating element 52 is provided. The heating element 52 is located inside the housing 51 and is used to dry the film material 100 that has passed through the baking assembly 5.

[0189] Multiple heating elements 52 can be provided, and the multiple heating elements 52 are distributed at intervals along the height direction of the housing 51. The distribution of heating elements 52 along the height direction reduces the overall size of the machine to a certain extent.

[0190] Multiple heating elements 52 can be evenly or unevenly distributed. Each heating element 52 can be configured to have the same power or different power, depending on the pattern or material to be dried.

[0191] like Figure 19 and Figure 20 As shown, in some embodiments, the exhaust structure 53 further includes a first fan 54, which is disposed at the bottom of the housing 51 and can blow air into the housing 51. By blowing air into the housing 51 through the first fan 54, the flow speed of the gas in the housing 51 can be accelerated, so that the exhaust generated in the housing 51 can be exhausted more quickly through the first exhaust pipe 532 and the second exhaust pipe 533 to the external exhaust gas purification device.

[0192] like Figure 8 and Figure 20 As shown, in order to prevent the membrane material 100 from being damaged by the heating element 52, the baking assembly 5 also includes an isolation box 55. The heating element 52 is disposed in the isolation box 55, so that the heating element 52 is isolated from the membrane material 100, and the membrane 100 is prevented from being damaged by the heating element 52 when passing through the baking assembly 5.

[0193] In some embodiments, the walls of the isolation box 55 are mesh-like. The mesh structure of the isolation box 55 does not affect the heating effect of the heating element 52, so that the heat generated by the heating element 52 can be evenly distributed to the outside of the isolation box 55 to dry the membrane material 100 and ensure the drying effect of the membrane material 100.

[0194] In other embodiments, the wall of the isolation chamber 55 may also be provided with multiple through holes, through which the heat generated by the heating element 52 can be dissipated to the outside of the isolation chamber 55 to dry the membrane material 100.

[0195] like Figure 20As shown, furthermore, to reduce heat loss within the baking assembly 5 and prevent the heat generated by the baking assembly 5 from affecting other components of the baking equipment 01, the outer wall of the housing 51 is provided with an insulation layer 512 and a heat-insulating material layer 513. The insulation layer 512 is disposed inside the heat-insulating material layer 513. Providing the insulation layer 512 and the heat-insulating material layer 513 on the side wall of the housing 51 improves the heat insulation effect between the inner and outer sides of the housing 51.

[0196] In some embodiments, the insulation layer 512 may be an aluminum foil layer. Aluminum foil has the ability to reflect heat and has a long-lasting thermal insulation function, which can reflect some heat back into the housing 51, reduce heat transfer, and has a long service life.

[0197] Furthermore, a mirror layer 514 is formed on the inner wall of the housing 51. The mirror layer 514 is disposed on the inner side of the insulation layer 512 and the heat insulation material layer 513. The mirror layer 514 generates heat radiation to the hot air, thereby reducing heat loss.

[0198] In this embodiment, three heating elements 52 are installed inside the housing 51, which can meet the drying requirements of most DTF printed parts. Two first fans 54 are provided, which are arranged side by side along the bottom of the housing 51 to meet the gas circulation requirements inside the housing 51.

[0199] Furthermore, to prevent the second transmission module 421 from overheating and affecting its service life, multiple cooling fans are connected to the outside of the housing 51. The cooling fans can be directed towards the second transmission module 421 to accelerate the airflow speed on the surface of the second transmission module 421, thereby improving the cooling effect of the second transmission module 421.

[0200] In summary, this application, by respectively providing a first mating part on the first conveying module and a second mating part on the film material, allows the film material to be fixed on the first and second conveying modules, thereby achieving single-sheet pattern printing and baking, reducing film material waste. The conveying sub-assemblies are divided into a first conveying sub-assembly and a second conveying sub-assembly, which can make fuller use of the space within the baking equipment and improve the compactness of the baking equipment. The first and second conveying sub-assemblies achieve synchronous transmission through a drive sub-assembly, improving the transmission accuracy of the conveying components and thus enhancing the conveying stability of the film material.

[0201] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of this application, and all such substitutions or changes should fall within the protection scope of the appended claims.
