Description

Technical Field

[0001] This utility model relates to the field of thermal sublimation transfer technology, and in particular to a thermal sublimation transfer device with film feeding function. Background Technology

[0002] Sublimation transfer printing is a process in which a pattern is first printed onto a film using special ink, and then transferred to the product to be printed by heating and baking. Sublimation transfer printing equipment is a type of printing equipment used to transfer the pattern from the film to the product to be printed. In related technologies, during each sublimation transfer process, the film needs to be manually laid on the worktable to cover the product placed on the worktable.

[0006] Because the thermal sublimation transfer equipment of this embodiment can drive the worktable to move between the working position and the loading position via a sliding drive mechanism, when the worktable is in the working position, it can avoid obstructing the vertical movement of the picking component. This allows the picking component to move from the waiting position to the picking position under the drive of the lifting drive, enabling it to enter the material bin to pick up the film. Subsequently, under the drive of the lifting drive, it can carry the picked-up film upwards to the waiting position above the working position. After the worktable moves to the loading position under the drive of the sliding drive mechanism and places the product to be transferred in the receiving slot, it is then lifted...

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] Reference Figures 1 to 5According to some embodiments of the present invention, a thermal sublimation transfer printing device with film feeding function includes a worktable 10, a sliding drive mechanism 20, a heating module 30, a storage module 40, and a feeding module 50. The worktable 10 is used to carry the product during the thermal transfer process. Therefore, the worktable 10 is provided with an upward-facing receiving groove 11 to accommodate and carry the product to be transferred. At the same time, to improve safety, the worktable 10 is made to be slidable, so that the worktable 10 can move between the working position and the feeding position. Thus, when the worktable 10 is in the working position, the pattern is transferred, and when in the feeding position, the product is fed manually or by a robot. The sliding drive mechanism 20 is a drive component that enables the automatic sliding of the worktable 10. The drive end of the sliding drive mechanism 20 is connected to the worktable 10, thereby enabling the worktable 10 to move between the loading position and the working position. The heating module 30 is used to heat the product and film on the worktable 10. The heating module 30 is located above the working position so that when the worktable 10 moves to the working position, the heating module 30 can heat the workpiece and film located below it and contained in the receiving groove 11, so as to cause the pattern on the film to sublimate at high temperature and transfer to the product. The storage module 40 is located below the loading position and includes a material bin 41 for stacking and storing the film to be transferred. The top of the material bin 41 has a material outlet 411, so that the material can be dispensing from the material bin 41. The top of the hopper 41 enters the hopper 41 to pick up the film; the loading module 50 includes a lifting driver 51 and a picking component 52. The picking component 52 is located above the hopper 41. The lifting driver 51 is connected to the picking component 52 and is used to drive the picking component 52 to move between the picking position below the picking port 411 and the waiting position above the loading position. Therefore, when the worktable 10 is in the working position, the lifting driver 51 can drive the picking component 52 to move down from the waiting position to the picking position to pick up the film, and then drive the picking component 52 to move up with the picked-up film to the waiting position; when the worktable 10 is in the loading position, the lifting driver 51 can drive the picking component 52 to move down from the waiting position to the receiving groove 11 to cover the product to be transferred in the receiving groove 11 with the film.

[0042] It should be understood that, because the thermal sublimation transfer equipment of this embodiment can drive the worktable 10 to move between the working position and the loading position via the sliding drive mechanism 20, when the worktable 10 is in the working position, it can prevent the worktable 10 from blocking the vertical movement of the picking component 52, thereby allowing the picking component 52 to move from the waiting position to the picking position under the drive of the lifting drive 51. This allows the picking component 52 to enter the material bin 41 from the picking port 411 to pick up the film, and then, under the drive of the lifting drive 51, it can carry the picked-up film up to the waiting position above the working position. After the worktable 10 moves to the loading position under the drive of the sliding drive mechanism 20 and places the product to be transferred in the receiving slot 11, it is driven by the lifting drive 51. The material picker 52 moves downward to place the film picked up by it onto the worktable 10 to cover and adhere to the product to be transferred, thereby realizing automated film feeding. After the film feeding is completed, the lifting driver 51 drives the material picker 52 to reset to the waiting position. Then, the sliding drive mechanism 20 drives the worktable 10 to slide to the working position. The heating module 30 above the working position heats the product and the film, so that the pattern on the film can be transferred to the product. Repeating the above process can realize continuous batch transfer of products. Therefore, the thermal sublimation transfer equipment of this embodiment can realize automated film feeding in the process of batch transfer of products, thereby reducing labor costs and improving efficiency, and can also effectively reduce the labor intensity of operators.

[0043] It is understood that, in some of these embodiments, reference is made to... Figure 3 The hopper 41 is formed by a plurality of mutually spaced limiting rods 412, which restrict the horizontal movement of the stacked films in the hopper 41. The top of the limiting rods 412 is connected to a plurality of crossbars 413. The area enclosed by the plurality of crossbars 413 constitutes the feeding port 411. The feeding component 52 is located above the hopper 41 and can be moved down through the feeding port 411 into the area enclosed by the plurality of limiting rods 412 under the drive of the lifting drive 51.

[0044] It should be understood that in some other embodiments, the hopper 41 may also be configured as a bin with four side walls and an open top.

[0045] It is understandable that, in order to enable the worktable 10 to slide between the loading position and the working position, in some embodiments, reference is made to... Figure 1 and Figure 5The thermal sublimation transfer equipment also includes a frame 60, on which a horizontally extending slide rail 61 is provided. The two ends of the slide rail 61 correspond to the loading and unloading positions, respectively. A slider 12 that cooperates with the slide rail 61 is provided at the bottom of the worktable 10. Thus, the worktable 10 can slide along the slide rail 61 by means of the cooperation between the slide rail 61 and the slider 12, allowing the worktable 10 to slide to the loading position at one end of the slide rail 61 or to the working position at the other end. Simultaneously, to drive the worktable 10 to slide precisely on the slide rail 61, so that when the worktable 10 moves to the working position, the film can be accurately laid onto the worktable 10, in some embodiments, refer to... Figure 5 The sliding drive mechanism 20 includes a servo motor 21 and a drive gear 22. The servo motor 21 is connected to the frame 60 and located on the lower side of the worktable 10. The drive gear 22 is connected to the drive shaft of the servo motor 21. The bottom of the worktable 10 is connected to a rack 13 that is parallel to the slide rail 61. The rack 13 cooperates with the drive gear 22, so that when the servo motor 21 rotates in the forward and reverse directions, it can drive the worktable 10 to slide in opposite directions on the slide rail 61 to switch from the loading position to the working position, or from the working position to the loading position.

[0046] It should be understood that, in order to drive the worktable 10 to switch between the working position and the loading position, in some other embodiments, the sliding drive mechanism 20 may also be selected to adopt other types of linear drive mechanisms such as cylinders, linear motor modules and electric push cylinders, without specific limitations.

[0047] It is understandable that, in order to ensure that the material-picking component 52 can move to a fixed picking position each time it picks up a piece of film, in some embodiments, reference is made to... Figure 3The storage module 40 also includes a lifting mechanism 42 and a first sensor 43. The lifting mechanism 42 includes a tray 421 and a lifting driver 422. The tray 421 is located inside the hopper 41 and is used to support stacked films. The lifting driver 422 is used to drive the tray 421 to rise and fall. The first sensor 43 is located on one side of the hopper 41 and is used to detect whether there are films at the picking position. The first sensor 43 is electrically connected to the lifting driver 422, and can control the operation of the lifting driver 422 based on the detection status of the first sensor 43. It should be understood that when storing films in the hopper 41, the lifting driver 422 can first drive the tray 421 down to the lowest position at the bottom of the hopper 41. Then, a certain number of films are stacked on the tray 421, and the total number of films on the tray 421 should make the height of the film stack slightly lower than the picking position. Then, when the heat sublimation transfer equipment is working, the first sensor 43... The system detects that the picking position does not have a diaphragm and controls the lifting driver 422 to drive the tray 421 to rise based on the detected signal. After the diaphragm at the top of the stack arrives at the feeding position, the first sensor 43 will detect that there is a diaphragm at the feeding position and then controls the lifting driver 422 to stop driving based on the detected signal, so that the topmost diaphragm in the stack remains at the picking position. This allows the picking member 52 to pick up the topmost diaphragm when it arrives at the picking position. After the topmost diaphragm in the stack is removed, the first sensor 43 will again detect that there is no diaphragm at the picking position and continues to control the lifting driver 422 to drive the tray 421 to rise based on the detected signal. This allows the diaphragm currently at the top of the stack (originally the second diaphragm from the top) to return to the feeding position, ready for the picking member 52 to pick up the diaphragm next time it arrives at the picking position.

[0048] It should be understood that, with reference Figure 3In some embodiments, the storage module 40 further includes a lifting frame 423. A lifting driver 422 is vertically disposed on one side of the hopper 41. The lifting frame 423 is connected to the drive end of the lifting driver 422, and part of the lifting frame 423 passes between two adjacent limiting rods 412 and enters the hopper 41. The pallet 421 is connected to the upper side of the lifting frame 423, so that when the lifting driver 422 drives the lifting frame 423 to rise and fall, the pallet 421 can be moved up and down. Furthermore, to allow the pallet 421 to remain at any different height within the hopper 41, the lifting driver 422 employs a motor-driven screw-nut mechanism. Simultaneously, a first sensor 43 is also disposed on one side of the hopper 41, positioned at a height corresponding to the material picking position. The detection end of the first sensor 43 faces horizontally between two adjacent limiting rods 412, thereby detecting whether a diaphragm exists at the material picking position. It should be understood that the first sensor 43 can be an infrared sensor or a photoelectric sensor.

[0049] Understandably, to ensure the film better adheres to the product within the receiving groove 11, the upper opening of the receiving groove 11 can be sealed by the film, and a vacuum can be drawn inside the receiving groove 11 to effectively remove air between the film and the product. This allows the film to adhere tightly to the product under negative pressure, thereby enabling the film to better adhere to products with curved printing surfaces and improving the accuracy of the pattern transfer process. To ensure the film effectively seals the opening of the receiving groove 11, in some embodiments, reference is made to... Figure 2 , Figures 6 to 10 The thermal sublimation transfer equipment also includes a film pressing mechanism 70, which includes a film pressing driver 71 and a film pressing frame 72. The film pressing frame 72 is disposed between the heating module 30 and the working position. The film pressing driver 71 is connected to the film pressing frame 72 and can drive the film pressing frame 72 to rise and fall. Furthermore, the size of the inner window area 721 of the film pressing frame 72 is greater than or equal to the size of the slot opening of the receiving groove 11 and smaller than the size of the top edge contour of the worktable 10. Thus, when the worktable 10 moves to the working position, the film pressing driver 71 can drive the film pressing frame 72 to move downward, so that the film pressing frame 72 presses the edge of the film against the upper surface of the worktable 10 and closes the receiving groove 11. At the same time, the heat generated by the heating module 30 (or the hot air mentioned below) can continue to be transferred downward to the film and product on the worktable 10 through the inner window area 721 of the film pressing frame 72.

[0050] It should be understood that, in some of these embodiments, reference is made to... Figure 8The bottom of the pressure film frame 72 is provided with an upwardly recessed annular recess 722. The annular recess 722 surrounds the window area 721 inside the pressure film frame 72, and an annular sealing gasket (not shown in the figure) is embedded in the annular recess 722. When the pressure film frame 72 moves down to press the film, the top of the worktable 10 can be embedded in the annular recess 722, and the pressure film frame 72 can abut against and press the film through the sealing gasket, so that the pressure film frame 72 can better cooperate with the film to seal the opening of the receiving groove 11.

[0051] It is understood that, in one embodiment, reference is made to... Figure 1 and Figure 6 The film pressing driver 71 includes two cylinders disposed on opposite sides of the working position. The two cylinders are fixedly connected to the frame 60 in a vertical direction, and the piston rods of the two cylinders are respectively connected to opposite sides of the film pressing frame 72 through connecting blocks, so as to drive the film pressing frame 72 to rise and fall by the two cylinders. It should be understood that in some other embodiments, other types of linear drive components such as linear motors or electric push cylinders may also be selected to drive the film pressing frame 72 to rise and fall.

[0052] Understandably, in some embodiments, in order to enable the film to adhere more tightly to the product surface, the thermal sublimation transfer equipment also includes a vacuum generator and a vacuum pipeline (not shown in the figures). The worktable 10 is provided with a vacuum channel, which is connected to the receiving tank 11. The vacuum generator is connected to the vacuum channel through the vacuum pipeline. After the pressing mechanism 70 presses the edge of the film onto the worktable 10, the air in the receiving tank 11 can be extracted by turning on the vacuum generator through the vacuum pipeline and the vacuum channel. This allows the air between the film and the product to be removed as well, so that the film adheres tightly to the product under negative pressure, thereby improving the quality of pattern transfer.

[0053] It should be understood that, in one embodiment, reference is made to... Figure 5 The vacuum generating device is a vacuum pump, and the vacuum channel includes an air extraction port 14 and an air passage (not shown in the attached figure). Multiple air extraction ports 14 are provided and are located at the bottom of the receiving tank 11. The air passage is located inside the worktable 10 and on the bottom wall of the receiving tank 11, and connects to each air extraction port 14. An air outlet (not shown in the attached figure) is formed on one side surface of the worktable 10, and is connected to one end of a vacuum pipeline through the air outlet. The other end of the vacuum pipeline is connected to the vacuum pump. In addition, in order to detect the air pressure in the receiving tank 11, the thermal sublimation transfer equipment also includes a negative pressure gauge. The negative pressure gauge is used to measure the air pressure value in the vacuum pipeline or air passage connected to the receiving tank 11, thereby obtaining the air pressure in the receiving tank 11.

[0054] Understandably, to prevent significant heat (or hot air, as will be mentioned below) from dissipating to the outside from between the top of the pressing frame 72 and the bottom of the heating module 30, in some embodiments, reference is made to... Figure 6 and Figure 10 The top of the film pressing frame 72 is provided with an upwardly protruding annular retaining member 73. The bottom of the heating module 30 is inserted into the annular retaining member 73, so that the heat generated by the heating module 30 can be guided to the worktable 10 below the film pressing frame 72 through the annular retaining member 73, thereby making the heat more concentrated on heating the film and product on the worktable 10. Furthermore, it should be understood that, in order to prevent the bottom of the heating module 30 from coming out of the annular retaining member 73 when the annular retaining member 73 moves down with the film pressing frame 72 to press the film, the height of the annular retaining member 73 is greater than the stroke of the film pressing frame 72 when it moves down to press the film, and when the film pressing frame 72 is in the position of pressing the film, the bottom of the heating module 30 is still inserted inside the annular retaining member 73.

[0055] It is understandable that, in order to improve the uniformity of heating the diaphragm and product on the worktable 10, in one embodiment, reference is made to... Figure 9 and Figure 10 The heating module 30 includes a heating box 31, a first fan 32, and a heating element 33. The bottom of the heating box 31 forms an air outlet 311. The heating element 33 is disposed inside the heating box 31. The first fan 32 is disposed at the top of the heating box 31 and is used to allow air to flow into the heating box 31 from the top. After being heated by the heating element 33, the air forms hot air that flows out from the air outlet 311. The hot air flowing out from the air outlet 311 will be guided by the annular baffle 73 and the film pressing frame 72 and blown onto the film and product on the worktable 10. In this way, the hot air heats the upper surface of the film from all directions, making the film and product more evenly heated.

[0056] It is understood that, in order to facilitate the installation and fixation of the heating element 33 inside the heating chamber 31, and to enable the heating element 33 to uniformly heat the air flowing through the heating chamber 31, so as to make the temperature of the hot air flowing through the air outlet 311 more uniform, thereby further improving the uniformity of heating the diaphragm and the product, in one embodiment, referring to Figure 9 and Figure 10The heating element 33 is a ceramic heater, and multiple ceramic heaters are provided. The heating module 30 also includes a mounting plate 34, which is horizontally disposed inside the heating box 31. Multiple ceramic heaters are mounted and fixed on the lower surface of the mounting plate 34, and the multiple ceramic heaters are evenly distributed on the mounting plate 34 in a matrix form. Therefore, when the air in the heating box 31 flows through the mounting plate 34, it can be evenly heated by the ceramic heaters, thereby making the temperature of the hot air more consistent. Furthermore, it should be understood that in order to allow the hot air to flow smoothly through the mounting plate 34, multiple perforated ventilation openings (not shown in the attached drawings) are provided on the mounting plate 34.

[0057] It is understandable that, in order to reduce heat loss and improve energy efficiency, in some embodiments, reference is made to... Figure 1 The thermal sublimation transfer equipment also includes a housing 80, in which the heating module 30 and the worktable 10 are both located inside the housing 80. This allows for hot air circulation within the housing 80 during the thermal transfer process, effectively limiting and isolating the heat emitted by the heating module 30 and the worktable 10 within the housing 80. The hot air blown by the heating module 30 onto the worktable 10 will eventually dissipate into the housing 80, raising the temperature of the air inside the housing 80. The air blown into the heating chamber 31 by the first fan 32 is also part of the air inside the housing 80. Since the air temperature inside the housing 80 is higher than that of the outside atmosphere, the amount of heat required for the film pattern to reach the thermal transfer temperature after being heated by the first heating element 33 is relatively smaller, resulting in greater energy savings.

[0058] It should be understood that, in some of these embodiments, reference is made to... Figure 1 The top of the chassis 80 is provided with a feeding port 81 in the area corresponding to the feeding position, so that when the worktable 10 slides to the feeding position, the product can be placed into the receiving slot 11 of the worktable 10 through the feeding port 81. In addition, in order to improve aesthetics and safety performance, in one embodiment, the storage module 40, the feeding module 50, the sliding drive mechanism 20, the frame 60 and the vacuum generator are all arranged inside the chassis 80, and the chassis 80 is provided with a door 83 corresponding to the position of the hopper 41, so as to replenish the film in the hopper 41.

[0059] It is understandable that, in order to avoid excessive heat accumulation inside the chassis 80, which could affect the normal operation of other components inside the chassis 80 besides the heating module 30, in some embodiments, reference is made to... Figure 1A second fan 82 is installed on the top of the chassis 80, corresponding to the area of ​​the heating module 30. The second fan 82 draws in outside air into the chassis 80, allowing for cooling by blowing in cool outside air when the air temperature inside the chassis 80 reaches a certain threshold. Furthermore, a temperature sensor is installed inside the chassis 80 to continuously monitor the internal temperature. The sensor's detection end is located between the outer wall of the heating chamber 31 and the inner wall of the chassis 80, detecting the air temperature between these two surfaces. The temperature sensor is electrically connected to the second fan 82, automatically activating it when the temperature exceeds a set upper threshold.
