Description

Technical Field

[0001] This application relates to the field of DTF printing technology, and in particular to 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 heat-transferred onto various textiles or other materials. The advantages of DTF printing include high precision, high color saturation, and excellent durability. DTF printing can achieve more complex patterns and colors, and is easy to operate with high production efficiency. 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 DTF printing, application of hot melt adhesive powder, baking, and hot stamping. Currently, the baking equipment used in the baking process typically uses conveyor rollers to transport the film material, requiring a relatively long roll. When users only need to print one or a few patterns, a long roll of film is still required, resulting in material waste and significantly reducing printing efficiency. Utility Model Content

[0062] This application provides a baking apparatus and a printing system. To make the objectives, technical solutions, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0065] Figure 1 This is a first-person view of the structural diagram of the printing system provided in this application.

[0066] like Figure 1 As shown, this application provides a printing system including a printer 02 and a baking device 01. The printer 02 may include a printhead. For example, the printhead may be an inkjet printhead, and the printer may be an inkjet printer. The printer 02 is used to print a pattern onto a film material 100. The baking device 01 may be located on the discharge side of the printer and is capable of receiving 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 sprinkle hot melt adhesive powder onto the film material 100 and melt the hot melt adhesive powder on the film material 100, so that the pattern on the film material 100 can be transferred to other objects (such as clothing, hats, etc.). The printing system may be a DTF printing system, etc., and no specific limitations are made here.

[0067] Generally, the film material 100 can be made of PET film. In one embodiment, the thickness of the film material 100 can be 0.75 mm. The film material 100 with the above-mentioned material and thickness has good transferability and can improve the clarity of the pattern transferred onto the product.

[0068] Figure 2 This is a first-view structural diagram of the baking equipment provided in this application.

[0069] 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 operations such as powdering and baking.

[0070] Figure 3 for Figure 2 A cross-sectional view along the AA direction.

[0071] 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. 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 side of the housing 1.

[0072] 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.

[0073] An inlet 11 is formed inside the outer casing 1. The membrane material 100 enters the outer casing 1 through the inlet 11. A buffer assembly 2 is disposed between the inlet 11 and the conveying assembly 4 to guide the membrane material 100 entering from the 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 and improving the conveying effect of the membrane material 100.

[0074] 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 from the top of the membrane material 100 onto the membrane material 100 and recover excess hot melt adhesive powder.

[0075] 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.

[0076] 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.

[0077] like Figure 1 and Figure 2 As shown, in some embodiments, the baking device 01 has a length direction a, a height direction b and a width direction c, the feed inlet is located on one side of the outer shell 1 in the width direction c, the powdering component 3 extends along the height direction b and the length direction a, the buffer component 2 extends along the length direction a, and the baking component 5 is located on one side of the powdering component 3 in the width direction c, and is located on the same side of the feed inlet 11 in the width direction c.

[0078] 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 the heat generated by the baking component 5 during equipment operation that would cause discomfort to the operator and improving the user experience.

[0079] 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. An 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 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 and avoiding occupying a large space in the width direction. The baking component 5 is located in the second receiving cavity 17 and below the installation space 15, which further makes full use of the space in the height and width directions, making the baking equipment structure layout more compact, smaller in size, and easier for users to operate.

[0080] Figure 4 This is a first-view schematic diagram of the internal structure of the baking equipment provided in this application.

[0081] 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 and 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, effectively utilizing the space of the second receiving cavity 17, optimizing the internal layout of the equipment. Furthermore, the receiving assembly 7 and the baking assembly 5 are located on different sides 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.

[0082] The receiving assembly 7 includes a receiving bin 71 and a guide 72. 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. 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.

[0083] The receiving bin 71 is detachably mounted on the housing 1 for easy removal. A guide 72 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 can be a component with a slope or curved surface (such as a ramp), or a fan. In this embodiment, the guide 72 is configured as a fan with its air outlet facing the receiving port 712. Multiple fans can be provided, and the fans are distributed at intervals along the width of the film material 100 detached 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 collected in the receiving bin 71.

[0084] 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.

[0085] 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-spreading 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. The controller 9 may include a main board and electronic components and interfaces mounted on the main board, which can be fixed to the frame 11 or the side plate 14. In one embodiment, the main board 9 can be housed within the second receiving cavity 17 and located on one side of the powder-spreading assembly 3 along the length direction a, thus making the structural layout more compact and fully utilizing the space of the second receiving cavity 17.

[0086] Figure 5 This 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 This is a schematic diagram of the structure of the buffer component provided in this application.

[0087] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the buffer assembly 2 includes a bracket 24, which is fixed inside the housing 1 and can serve as a support structure for the buffer assembly 2.

[0088] The bracket 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.

[0089] The buffer assembly 2 includes a swing member 21, which is swingably mounted on the bracket 24, specifically on at least one mounting plate 241.

[0090] 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.

[0091] 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, having a first position and a second position. The oscillating member 21 can oscillate within the range between the first and second positions. 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 and second positions.

[0092] In the initial state, the swing member 21 is in the second position. When the membrane 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 membrane material 100 can pass through the feeding surface 211 of the swing member 21 and be conveyed to the conveying assembly 4 and fixed on the transmission assembly 4. After the membrane 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 membrane material 100, and the membrane material 100 will be pressed down under the action of gravity to form an arc shape.

[0093] like Figure 7As 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 and second sub-conveyor surfaces 2112 and 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 and reach the conveying assembly 4.

[0094] The buffer assembly 2 includes a second motor 22. The second motor 22 is mounted on the bracket 24 and is connected to the swing member 21 for driving the swing member 21 to swing.

[0095] 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 connected to the other end of the swing member 21 for transmission, 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.

[0096] 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 and is used to detect whether the film material has reached the conveying assembly 4. When the first sensor 43 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 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.

[0097] 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 set 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.

[0098] When the swing member 21 swings to the first position, the second sensor 23 generates 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, 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.

[0099] 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 mounted on the housing 1.

[0100] 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 conveying assembly 4 stops conveying the film material 100. Under the pushing action of the printer, the film material 100 droops in the buffer assembly 2 and forms a downward curved 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 to convey 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 forms a downward curved arc again in the buffer assembly 2. This cycle repeats, realizing the automatic feeding of the film material 100.

[0101] In some embodiments, the first sensor 27, the second sensor 23, and the third sensor 26 may be sensors of the type such as photoelectric sensors. The first sensor 27, the second sensor 23, and the third sensor 26 are each electrically connected to the controller 9.

[0102] In some embodiments, to further limit 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.

[0103] like Figure 3 and Figure 5As 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. 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.

[0104] 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.

[0105] like Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the conveying assembly 4 includes a first conveying sub-assembly 41, a second conveying sub-assembly 42, a transmission sub-assembly 43, and a first motor 44. The first motor 44 is driven by the transmission sub-assembly 43, and the transmission sub-assembly 43 is driven by the first conveying sub-assembly 41 and the second conveying sub-assembly 42. Part of the first conveying sub-assembly 41 is located on the side of the powder-spreading assembly 3 away from the feed inlet 11, and part of the first conveying sub-assembly 41 is located below the powder-spreading assembly 3 in the height direction. The second conveying sub-assembly 42 surrounds at least part of the baking assembly 5. During the process of conveying the film material 100 by the conveying assembly 4, the film material 100 can be transferred from the first conveying sub-assembly 41 to the second conveying sub-assembly 42.

[0106] The transmission subassembly 43 connects the first transmission subassembly 41 and the second transmission subassembly 42, reducing the need for the first motor 44 and simplifying the equipment structure. Furthermore, it improves the accuracy of the synchronous transmission between the first and second transmission subassemblies 41 and 42, thereby enhancing the stability of the film material 100 transmission. The first transmission subassembly 41 transports the film material 100 to the front of the baking assembly 5, while the second transmission subassembly 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 subassembly 41, space is fully utilized, reducing the overall size of the baking equipment.

[0107] Furthermore, in some embodiments, the first transmission sub-assembly 41 includes two first transmission modules 411 and a first transmission member 412 arranged at intervals along the length direction a. The first transmission member 412 is connected to the two first transmission modules 411 in a transmission manner. 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.

[0108] For example, the first transmission module 411 includes a synchronous belt and multiple drive pulleys. The synchronous belt can mesh with the multiple drive pulleys, which together form a polygon. The multiple drive pulleys can support the synchronous belt and drive its movement. A first transmission member 412 can extend along the length direction a and drively connect to one of the drive pulleys in the two first transmission modules 411. The first transmission member 412 can be a drive shaft, and one of the drive pulleys in the two first transmission modules 411 can be fixed to both ends of the drive shaft in the axial direction. One of the drive pulleys in one of the first transmission modules 411 can be connected to a transmission sub-assembly 43 and move under the transmission of the transmission sub-assembly 43.

[0109] Furthermore, in some embodiments, the second transmission sub-assembly 42 includes two second transmission modules 421 and a second transmission member 422 arranged at intervals along the length direction a. The second transmission member 422 is connected to the two second transmission modules 421 in a transmission manner. The second transmission member 422 can realize the synchronous transmission of the two second transmission modules 421, and the two second transmission modules 421 can support both ends of the membrane material 100.

[0110] For example, the second transmission module 421 includes a synchronous belt and multiple drive pulleys. The synchronous belt can mesh with the multiple drive pulleys, which together form a polygon. The multiple drive pulleys can support the synchronous belt and drive its movement. The second transmission member 422 can extend along the length direction a and drively connect to one of the drive pulleys in the two second transmission modules 421. The second transmission member 422 can be a drive shaft, and one of the drive pulleys in the two second transmission modules 421 can be fixed to both ends of the drive shaft in the axial direction. One of the drive pulleys in one of the second transmission modules 421 can be connected to a transmission sub-assembly 43 and move under the transmission of the transmission sub-assembly 43.

[0111] Please see Figure 10 The transfer assembly 4 also includes a guide portion 45 disposed between the first transfer sub-assembly 41 and the second transfer sub-assembly 42. The guide portion 45 is used to guide the membrane material 100 from the first transfer sub-assembly 41 to the second transfer sub-assembly 42 to realize the transfer of the membrane material 100.

[0112] like Figure 5As 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.

[0113] The second transmission sub-assembly 42 further includes a second limiting member 423, which is disposed on the outside of the second transmission module 421 to restrict the membrane material 100 from detaching from the second transmission module 421. For example, the second limiting member 423 may be a guide rail, which may wrap around at least a portion of the second transmission module 421.

[0114] 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 can be 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 can be ensured that the film material 100 will not detach from the second conveying sub-assembly 42.

[0115] 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 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.

[0116] The guide portion 45 includes a second guide portion 452. The second guide portion 452 is formed on the side of the second limiting member 423 near the first transfer sub-assembly 41. The second guide portion 452 has an inclined surface facing the first transfer sub-assembly 42, 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 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.

[0117] 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, and the second conveying module 421 rotates counterclockwise. Thus, under the rotation of the first conveying module 411 and the second conveying module 421, and under the action of the second guide part 452, the membrane material 100 can be transferred from the first conveying module 411 to the second conveying module 421 when the first conveying module 411 and the second conveying module 421 are close to each other.

[0118] In some embodiments, the guide portion 45 further includes a first guide portion 451, which is located on the side of the first limiting member 413 near the second transmission sub-assembly 42, and the first guide portion 451 is offset from the second guide portion 452. The first guide portion 451 is formed with an inclined surface extending toward the second transmission sub-assembly 42, which can guide the membrane material 100 to gradually detach from the first transmission member 412.

[0119] The conveying component 4 is configured as a first conveying sub-component 41 and a second conveying sub-component 42. This can optimize the conveying direction of the conveying component 4 within a limited space, reduce the frequency of changes in the transmission angle of a single-segment transmission component, improve the stability of the membrane material 100 conveying, facilitate the layout of each component, and improve the compactness of the overall structure, thereby reducing the overall size of the machine.

[0120] In some embodiments, the first limiting member 413 is further provided with a third guide portion 4131 at one end near the buffer assembly 2. The third 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 third guide port can gradually approach the first transmission member 412, thereby connecting to the conveying assembly 4 and moving with the conveying assembly 4. The third guide portion 4131 may have a guide curved surface or a guide inclined surface, and the tangent angle can gradually decrease when the guide curved surface is used.

[0121] In some embodiments, the first sensor 43 may be disposed at the third guide portion 4131 to detect whether the film material 100 enters the conveying component 4 from the buffer assembly 2. When the first sensor 43 detects that the film material 100 is connected from the buffer assembly 2 to the conveying component 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 component 3 to spray powder onto the film material 100.

[0122] like Figure 5 and Figure 8As shown, in some embodiments, the transmission subassembly 43 further includes a first gear 431, a second gear 432, and a third gear 433. The first gear 431 is disposed between the second gear 432 and the third gear 433, meshing with both gears. The first gear 431 is also connected to one of the first transmission modules 411 in the first transmission subassembly 41, thereby driving the first transmission module 411 to rotate synchronously. The rotation direction of the first gear 431 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 subassembly 42. The second gear 432 is connected to one of the second transmission modules 421 in the second transmission subassembly 42, thereby driving the second transmission module 421 to rotate synchronously. The third gear 433 is connected to the first motor 42. In the above embodiments, the transmission accuracy is improved by using the transmission subassembly 43, while eliminating the need for multiple motors to drive the first transmission subassembly 41 and the second transmission subassembly 42 respectively.

[0123] Figure 10 for Figure 9 Enlarged view of region C in the image.

[0124] In some embodiments, the conveying assembly 4 is provided with a first mating part 46, which is used to mate with a second mating part on the membrane material 100 to fix the membrane material 100 to the conveying assembly 4.

[0125] In some embodiments, the two first conveying modules 411 are provided with first mating portions 46, and second mating portions are provided on both sides of the membrane material 100 in the width direction. The first mating portions 46 and the second mating portions mate, so that the membrane material 100 can be fixed on the conveying assembly 4 through the connection of the first mating portions 46 and the second mating portions. The two second conveying modules 421 are also provided with first mating portions 46 to fix the membrane material 100 on the second conveying module 421.

[0126] like Figure 5 , Figure 9 and Figure 10As shown, in some embodiments, multiple first mating portions 46 are provided on the first conveying module 411, and the multiple first mating portions 46 are equally spaced. The first mating portions 46 are configured as bosses, and the second mating portions are configured as fixing holes. There are multiple second mating portions, which are equally spaced, and the spacing is the same as that of the multiple first mating portions 46. The fixing holes on the film material 100 can pass through the bosses to fix it to the conveying assembly 4. Multiple bosses are provided, and the multiple bosses are distributed at intervals along the length direction of the conveying. A film material 100 can be fixed on multiple bosses to improve the fit between the film material 100 and the conveying assembly 4. The multiple first mating portions 46 are equally spaced so that the film 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.

[0127] 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 set to be conical.

[0128] The fixing 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 fixing holes can also be round holes.

[0129] like Figure 5 and Figure 8 As shown, in other embodiments, the transmission component 4 includes an encoder 47 and a sixth sensor 48. The encoder 47 is provided with circumferential teeth, and the distance between two adjacent teeth is equal to the distance between two adjacent bosses. The rotation trajectory of the encoder 47 is within the detection range of the sixth sensor 48, which is used to detect the rotation distance of the encoder 47.

[0130] The code disk 47 is connected to the first transmission sub-assembly 41 and the second transmission sub-assembly 42 via the transmission sub-assembly 43. Specifically, the code disk 47 is coaxially arranged with the first gear 431. The first gear 431, the second gear 432, and the third gear 433 have the same radius of rotation. The sixth sensor 48 is disposed on one side of the code disk 47 and is used to detect the rotation distance of the code disk 47. When the teeth of the code disk 47 pass the sixth sensor 48, the sixth sensor 48 generates an excitation signal. Multiple teeth on the code disk 47 can correspond to multiple first mating parts. By detecting the position of the teeth on the code disk 47 by the sixth sensor 48, it is determined whether the first mating part 46 has moved to the engagement position, thereby controlling the transmission of the membrane material 100 and engaging the second mating part on the membrane material 100 with the first mating part 46 to accurately fix it on the first transmission sub-assembly 41.

[0131] Figure 11 for Figure 3 Enlarged view of region B in the image.

[0132] The powder application assembly 3 includes a powder application mechanism 31. 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-curving arc. At this time, the powder application mechanism 31 applies hot melt adhesive powder to the film material 100, allowing the hot melt adhesive powder to be more evenly distributed on the surface of the film material 100 and better covering the pattern.

[0133] Figure 12 This is a schematic diagram of the powder-spreading mechanism provided in this application.

[0134] like Figure 3 , Figure 11 and Figure 12 As shown, the powder dispensing mechanism 31 further includes a powder dispensing bin 311, a powder dispensing roller 313, and a third motor 314. The powder dispensing bin 311 is positioned above the buffer assembly 2, and both ends of the powder dispensing bin 311 are fixed to the bracket 24. A powder dispensing port is provided at the bottom of the powder dispensing bin 311 to facilitate the discharge of hot melt adhesive powder. 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 across the width of the film material 100. The powder-spraying roller 313 is disposed in the powder-spraying nozzle and extends along the length of the powder-spraying nozzle. One end of the powder-spraying 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 connected to the other end of the powder-spraying roller 313 for driving the powder-spraying roller 313 to rotate, so as to carry the hot melt adhesive powder in the powder-spraying chamber 311 out from the powder-spraying nozzle and spread it downward onto the film material 100.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] Figure 13 This is a schematic diagram of the powder-spreading roller provided in this application.

[0139] like Figure 12 and Figure 13 As 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.

[0140] 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.

[0141] 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 311 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.

[0142] 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.

[0143] Two powder scrapers 315 are located on both sides of the powder spreading roller 313 along its axis, 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.

[0144] 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 scrapers 315 to insert into the powder trough 3131 when the powder-spreading roller 313 rotates, effectively carrying 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 scraper 315 is located in front of the powder-spreading roller 313 and is inclined downwards; the other scraper 316 is located behind the powder-spreading roller 313 and is inclined upwards.

[0145] The powder scraper 315 is a brush, which includes a soft part that contacts the powder-spreading roller 313. This soft part 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 a soft material, such as a silicone strip.

[0146] Figure 14 This is a schematic diagram of the powder-spraying component provided in this application.

[0147] like Figure 3 , Figure 6 and Figure 14 As shown, the powder dispensing component 3 includes a powder storage mechanism 32. The powder storage mechanism 32 is located below the buffer component 2 and is used to store and recycle hot melt adhesive powder.

[0148] The powder storage mechanism 32 has a powder recovery chamber 321a1 and a powder storage chamber 321b1 that are connected. The powder recovery chamber 321a1 is closer to the powder spreading mechanism 3 than the powder storage chamber 321b1. The powder spreading mechanism 3 is correspondingly located above the powder recovery chamber 321a1. The buffer assembly 3 is at least partially located in the powder recovery chamber 321a1 and can swing within the powder recovery chamber 321a1. The powder dispensing mechanism 3 is positioned above the powder recovery chamber 321a1. The buffer component 3 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 applies hot melt adhesive powder to the film material 100. The powder recovery chamber 321a1 is connected to the powder storage chamber 321b1. The hot melt adhesive powder collected in the powder recovery chamber 321a1 can fall directly into the powder storage chamber 321b1, eliminating the need for frequent cleaning and improving the user experience.

[0149] The powder storage mechanism 32 includes a powder storage bin 321, which 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 bin 321. The powder storage bin 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 bin 321, facilitating the recycling of hot melt adhesive powder.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] The powder storage mechanism 32 includes a powder filling hopper 322. The powder filling hopper 322 is rotatably and retractably installed in the powder storage hopper 321 and is used to store hot melt adhesive powder. The powder filling hopper 322 has a powder filling port, through which the hot melt adhesive powder in the powder filling hopper 322 can be poured into the powder storage hopper 321.

[0154] Figure 15 This is a structural schematic diagram of the baking equipment provided in this application from a second perspective.

[0155] 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.

[0156] Figure 16This 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.

[0157] like Figures 16 to 18 As shown, a third limiting protrusion 3222 is formed on the side wall of the powder filling hopper 322, and the protrusion direction of the third limiting protrusion 3222 is consistent with the opening direction of the powder filling hopper 322. A first notch 32141 is formed on the upper part of the first through hole 3214, and the third limiting protrusion 3222 corresponds to and is adapted to the first notch 32141.

[0158] 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 upward, and the powder filling bin 322 can be pulled out from 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 opening of the powder filling trough 3221 faces downward, and the hot melt adhesive powder in the powder filling hopper 322 can be transferred to the powder storage hopper 321.

[0159] In some embodiments, the first limiting protrusion 3212 and the second limiting protrusion 3213 are disposed at both ends of the first through hole 3214 in the radial direction. The second limiting protrusion 3213 limits the third limiting protrusion 3222 to the bottom of the first through hole 3214. In this way, when the powder filling hopper 322 pours hot melt adhesive powder into the powder storage hopper 321, the opening of the powder filling trough 3221 faces downward, ensuring that the hot melt adhesive powder in the powder filling hopper 322 can fall completely into the powder storage hopper 321.

[0160] 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.

[0161] The powder storage bin 321 is also provided with a sleeve 3216, which can support the powder filling bin 322 and can rotate relative to it to allow the powder filling bin 322 to rotate more smoothly. 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.

[0162] 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 is lower than a certain level, the fourth sensor 323 will issue an alarm to prompt the addition of powder.

[0163] Furthermore, multiple fourth sensors 323 can be installed at different heights within the powder storage bin 321 to generate different powder addition signals.

[0164] like Figure 15 As shown, further, 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. A powder filling cover 6 is attached to the powder filling port 12 to close the powder filling port 12 and prevent accidental contact with the powder filling chamber 322.

[0165] 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.

[0166] 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.

[0167] like Figure 3 and Figure 6 As shown, the powder dispensing assembly 3 includes a powder circulation mechanism 33. The powder circulation mechanism 33 is distributed within the powder dispensing mechanism 31 and the powder storage mechanism 32, and is used to transfer the hot melt adhesive powder in the powder storage mechanism 32 to the powder dispensing mechanism 31.

[0168] The powder circulation mechanism 33 includes a powder circulation synchronous belt 331, a transmission structure 335, and a fourth motor 332. The powder circulation synchronous belt 331 forms a circulation loop between the powder spreading mechanism 31 and the powder storage mechanism 32. The outer side of the powder circulation synchronous belt 331 is provided with multiple protruding toothed portions 3311, which are spaced apart along the length of the powder circulation synchronous belt 331. A space for carrying hot melt adhesive powder is formed between two adjacent toothed portions 3311.

[0169] The transmission structure 335 includes a driving wheel 3351 and a plurality of driven wheels 3352. The driving wheel 3351 and the driven wheels 3352 are respectively located in the circulation direction 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 335.

[0170] 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.

[0171] The powder circulation synchronous belt 331 is connected to the driving wheel 3351 and the driven wheel 3352, and forms a circulation loop between the powder spreading mechanism 31 and the powder storage mechanism 32. Part of the powder circulation synchronous belt 331 is located above the powder spreading mechanism 31, and part of the powder circulation synchronous belt 331 is located in the powder storage mechanism 32. The powder circulation synchronous belt 331 is used to carry out part of the hot melt adhesive powder in the powder storage mechanism 32 and transfer it to the powder spreading assembly 3.

[0172] 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.

[0173] 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.

[0174] 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. 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.

[0175] The powder unloading component 334 can cover most of the position of the powder circulation mechanism 33 in the powder dispensing chamber 311, so that the hot melt adhesive powder can be transferred to the powder dispensing chamber 311 more evenly, thereby improving the uniformity of hot melt adhesive powder adhesion on the film material 100. Preferably, multiple powder unloading components 334 are arranged at intervals along the length direction of the powder dispensing chamber 311, which not only enables the hot melt adhesive powder to be transferred to the powder dispensing chamber 311 more evenly, but also reduces the friction between the powder unloading component 334 and the powder circulation mechanism 33.

[0176] 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.

[0177] 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 inserted into the powder storage mechanism 32 and is rotatably connected to the powder circulation synchronous belt 331, and is used to adjust the tension of the powder circulation synchronous belt 331.

[0178] 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 pulleys 3352 of the powder circulation synchronous belt 331. 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.

[0179] like Figure 14 and Figure 16 As shown, the powder-spreading assembly 3 also includes a powder-tapping mechanism 34. The powder-tapping mechanism 34 is disposed between the powder-spreading mechanism 31 and the powder storage mechanism 32, and is located in the conveying path of the membrane material 100. The powder-tapping mechanism 34 is used to tap the membrane material 100 after the hot melt adhesive powder is spread, so as to shake off the hot melt adhesive powder that is not adhered to the membrane material 100.

[0180] 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. The fifth motor 341 is connected to the rotating shaft 342 for driving the rotating shaft 342 to rotate. When the rotating shaft 342 rotates, the tapping element 343 can rotate to the back of the membrane material 100 located in the buffer assembly 2 and contact the back of the membrane material 100 to tap the membrane material 100, shake off excess hot melt adhesive powder on the membrane material 100, and improve the utilization rate of hot melt adhesive powder.

[0181] When the powder-tapping mechanism 34 is in operation, the fifth motor 341 rotates in both forward and reverse directions in a cycle, so that the tapping component 343 can produce intermittent tapping action on the membrane material 100.

[0182] 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.

[0183] 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. The end of the swing member 21 facing away from the feed inlet 11 is provided with a clearance groove 214. 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 are correspondingly arranged with the tapping member 343. The powder-tapping mechanism 34 can rotate until the tapping member 343 is inserted into the clearance groove 214, and can tap the back of the film material 100 located in the buffer assembly 2 to shake off the unadhered hot melt adhesive powder on the film material 100. This results in a more compact structural layout, which is beneficial for miniaturization.

[0184] like Figure 14 As 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.

[0185] 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.

[0186] like Figure 3 , Figure 19 and Figure 20As 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 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.

[0187] 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.

[0188] 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 inside of the housing 51. The first exhaust pipe 532 communicates with the air outlet of the exhaust fan 531. The second exhaust pipe 533 communicates with the first exhaust pipe 532, and the other end of the second exhaust pipe 533 is 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, so that a Bernoulli fluid is formed inside the exhaust structure 53, thereby increasing the exhaust gas emission speed inside the housing 51.

[0189] Furthermore, the first exhaust pipe 532 and the second exhaust pipe 533 are axially connected and are located inside the baking chamber 51, which improves the compactness of the baking equipment 01 to a certain extent and reduces the volume of the baking equipment 01.

[0190] 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.

[0191] 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.

[0192] Multiple heating elements 52 can be evenly or unevenly distributed. Each heating element 52 can be set to the same power or different power, depending on the pattern or material to be dried.

[0193] In some embodiments, the exhaust structure 53 includes a first fan 54, a first exhaust pipe 532, and a second exhaust pipe 533. The first fan 54 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 convection speed inside the housing 51 can be accelerated, so that the exhaust gas generated inside the housing 51 can be discharged more quickly into the exhaust gas purification device through the first exhaust pipe 532 and the second exhaust pipe 533.

[0194] like Figure 8 and Figure 20 As shown, to prevent the membrane material 100 from being damaged by the heating element 52, the baking assembly 5 also includes an isolation chamber 55. The wall of the isolation chamber 55 is mesh-like, and the heating element 52 is disposed inside the isolation chamber 55, thus isolating the heating element 52 from the membrane material 100. The mesh structure of the isolation chamber 55 does not affect the heating effect of the heating element 52, ensuring the drying effect of the membrane material 100.

[0195] like Figure 20 As 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 sidewalls of the housing 51 have an aluminum foil layer 512 and an insulation material layer 513. Furthermore, the inner wall of the housing 51 has a mirror layer 514, which radiates heat to the hot air, reducing heat loss.

[0196] In this embodiment, three heating elements 52 are installed inside the chamber 51, which can meet the drying requirements of most DTF printed parts. Two first fans 54 are provided, and the two first fans 54 are arranged side by side along the bottom of the chamber 51 to meet the gas circulation requirements inside the chamber 51.

[0197] 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 exhaust direction of 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.

[0198] In summary, this application achieves seamless connection between the printer and the conveying assembly by placing a buffer component directly opposite the feed inlet. This eliminates the problem of surface tension variations affecting the conveying effect during film feeding. Furthermore, by fixing the two edges of the film with protrusions on the conveying assembly, single-sheet conveying of the film is achieved, improving film utilization and thus enhancing the flexibility of customized solutions. The conveying of the film between the buffer component and the conveying assembly is controlled by a first, second, and third sensor, enabling automated film feeding. The conveying assembly, through a first and a second conveying sub-assembly, achieves segmented film conveying, and the baking components are distributed along the height of the outer shell, optimizing the arrangement of components within the baking equipment and improving the overall compactness of the machine.

[0199] 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 these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
