TECHNICAL FIELD

[0001] The present application relates to the technical field of vamp processing, in particular to a TPU hot melt adhesive film processing equipment for vamp heat transfer printing. BACKGROUND

[0002] The heat transfer printing on the vamp can be divided into two parts. One is to customize the pattern according to the design, that is, to make a stencil, which only needs to provide the pattern to the manufacturer, and the manufacturer prints the pattern on the TPU hot melt adhesive film. The other is to perform heat transfer printing processing, that is, to transfer the pattern on the TPU hot melt adhesive film to the vamp by heating and pressing.

[0003] At present, a manufacturing method of silica gel heat transfer printing pattern is disclosed in Chinese patent No. CN107264161, published on October 20, 2017, which includes the following steps: step one, surface modification of the TPU hot melt adhesive film by a surface treatment agent to form a surface treatment layer; step two, coating of addition liquid silica gel with a thickness of 5-30 silk on the modified TPU hot melt adhesive film, drying to form a silica gel heat transfer printing coating layer; the drying temperature is 120-160℃, and the drying time is 1-5 minutes; step three, using a laser engraving machine to engrave the silica gel heat transfer printing coating layer from one side of the TPU hot melt adhesive film to obtain the required pattern, completing the manufacturing process of the silica gel heat transfer printing pattern.

[0004] After coating the addition liquid silica gel on the TPU hot melt adhesive film, it needs to be dried for 1-5 minutes, and an oven is often used in the prior art. For example, a kind of oven is disclosed in Chinese patent No. CN217265822U, published on August 23, 2022, which includes a base frame, an oven for drying is arranged on the base frame, a transmission belt for conveying leather into the oven is arranged on the base frame, a fixing assembly is arranged on the transmission belt, the fixing assembly is used to press the leather on the transmission belt, a rotating roller is rotatably arranged on the base frame, the rotating roller is used to press on the surface of the leather, and the rotating direction of the rotating roller is opposite to the conveying direction of the transmission belt.

[0005] When this kind of oven is applied to dry the TPU hot melt adhesive film, the TPU hot melt adhesive film is laid on the processing plate, then the liquid silica gel is coated on the TPU hot melt adhesive film, and then the processing plate is placed on the transmission belt. The TPU hot melt adhesive film is conveyed into one end of the oven through the transmission belt, and when the TPU hot melt adhesive film is moved out of the other end of the oven along with the transmission belt, the whole drying process is completed.

[0006] However, when coating the liquid silica gel on the TPU hot melt adhesive film, the prior art is mostly coated by manpower through a scraper, which may cause uneven coating. SUMMARY

[0007] The application aims to provide a TPU hot melt adhesive film processing device for shoe upper heat transfer printing, which is beneficial to uniformly coating liquid silicone on the TPU hot melt adhesive film.

[0008] The above technical purpose of the application is achieved by the following technical scheme: a TPU hot melt adhesive film processing device for shoe upper heat transfer printing, comprising a machine body, an oven arranged on the machine body in a long strip shape, a conveying belt arranged on the machine body and passing through the oven, a processing plate for laying the TPU hot melt adhesive film, and a workbench arranged at a feeding end of the conveying belt, both ends of one side of the workbench are provided with open grooves, a driving shaft is rotatably connected to a position below the open groove on one side of the workbench, a driving wheel protruding above the open groove is arranged on the driving shaft, a driven shaft is rotatably connected to a position below the open groove on the side away from the driving shaft, a driven wheel protruding above the open groove is arranged on the driven shaft, a driving motor is arranged below the workbench and connected to the driving shaft, a first storage box for containing liquid silicone is arranged below the workbench, a guide roller is rotatably connected in the first storage box, a conveying film for the liquid silicone to adhere to the surface is arranged on the workbench and passes through the driving wheel, the driven wheel and the guide roller, and a feeding mechanism for pressing the lower surface of the conveying film against the processing plate is arranged above the conveying film on the workbench.

[0009] Further, the feeding mechanism comprises a bracket arranged on the upper side of the workbench, a rodless cylinder arranged on the bracket and extending in a direction parallel to the conveying direction of the conveying film, a lifting cylinder arranged on the moving block of the rodless cylinder and extending in a vertical downward direction, a support arm arranged on the end of the piston rod of the lifting cylinder and in a "H" shape, a fixed shaft arranged on the lower side of the support arm, and a rubber sleeve arranged on the fixed shaft and used for abutting against the outer wall of the conveying film.

[0010] Further, a positioning rod in an "H" shape is arranged on the upper surface of the workbench and embedded in the processing plate, and the positioning rod is below the conveying film.

[0011] Further, the width of the positioning rod is smaller than the thickness of the processing plate.

[0012] Further, an opening is arranged at the end of the workbench away from the conveying belt, a second storage box for containing water and placing the processing plate to be laid with the TPU hot melt adhesive film is arranged below the opening, and a coating mechanism for coating the water on the surface of the processing plate is arranged in the second storage box.

[0013] Further, positioning arms for abutting against both sides of the processing plate are arranged on both sides of the opening.

[0014] The second storage box is further provided with a positioning groove for embedding the end of the processing plate below the positioning arm.

[0015] The coating mechanism comprises a connecting shaft arranged at the end of the driven shaft and penetrating through the second storage box, a connecting spring having one end connected with the connecting shaft away from the end of the driven shaft, a mounting shaft arranged at the end of the connecting spring away from the connecting shaft, a mounting sleeve sleeved on the mounting shaft, and a fluff layer arranged on the side of the mounting sleeve and used for abutting against the surface of the processing plate.

[0016] The end of the mounting shaft away from the connecting spring is provided with a threaded end, and a mounting nut for abutting against the end of the mounting sleeve is threadedly connected on the threaded end.

[0017] Therefore, the present application has the following advantages:

[0018] 1. Firstly, the driving motor drives the driving wheel to rotate, thereby driving the transmission film through the driven wheel and the guide roller, wherein a part of the transmission film passes above the workbench due to the upper protrusion of the driving wheel and the driven wheel from the opening groove, and the transmission film passes the surface of the guide roller and is attached with the liquid silicone in the first storage box;

[0019] After the TPU hot melt adhesive film is laid on the processing plate, the processing plate can be placed below the transmission film with the side with the TPU hot melt adhesive film upward, and then the lower surface of the transmission film can be pressed on the processing plate by the feeding mechanism, so that a part of the liquid silicone attached to the lower surface of the transmission film is printed on the surface of the TPU hot melt adhesive film.

[0020] 2. After the processing plate is placed below the transmission film, the supporting arm is lowered by the lifting cylinder, and the rubber sleeve on the lower side of the supporting arm can press the transmission film downward and abut against the surface of the TPU hot melt adhesive film on the processing plate, and then the lifting cylinder is translated along the transmission direction of the transmission film by the non-inductive cylinder, so that the rubber sleeve can roll on the processing plate, and finally a part of the liquid silicone attached to the lower surface of the transmission film is printed on the surface of the TPU hot melt adhesive film;

[0021] Then the driving motor continues to drive the transmission film to drive, so that the transmission film losing a part of the liquid silicone is sent into the first storage box again, and finally the transmission film can easily attach new liquid silicone, which is convenient for the next operation.

[0022] 3. When it is necessary to place the processing plate under the transmission film, the positioning rod in the shape of "冂" arranged on the upper surface of the workbench can be used. The processing plate can be inserted into the positioning rod, so as to position the position of the processing plate under the transmission film and avoid the situation that the processing plate is offset after the rubber sleeve is tightly pressed on the processing plate;

[0023] 4. The width of the positioning rod is smaller than the thickness of the processing plate, which is beneficial to the rubber sleeve to be stably pressed on the processing plate;

[0024] 5. When the TPU hot melt adhesive film needs to be laid on the processing plate, in order to avoid the TPU hot melt adhesive film from shifting on the processing plate, a layer of water needs to be coated between the processing plate and the TPU hot melt adhesive film. At this time, after the gap between the processing plate and the TPU hot melt adhesive film is filled with water, the air can be removed, and the atmospheric pressure can tightly press the TPU hot melt adhesive film on the processing plate, which is finally beneficial to the stable laying of the TPU hot melt adhesive film on the processing plate;

[0025] Among them, the second storage box is arranged on the lower side of the opening of the workbench, and the second storage box is used for storing water. After the processing plate is placed in the second storage box, the coating mechanism is used to coat the water in the second storage box on the surface of the processing plate, which is finally beneficial to quickly coat the surface of the processing plate with water;

[0026] 6. When the processing plate is placed in the second storage box, the positioning arms arranged on both sides of the opening are used. The two positioning arms can respectively contact both sides of the processing plate, so as to position the position of the processing plate in the second storage box;

[0027] 7. The processing plate is vertically inserted between the two positioning arms, and then the lower end of the processing plate can be inserted into the positioning groove in the second storage box. The vertically placed processing plate is convenient for the operator to take;

[0028] 8. When the driven shaft rotates, it can simultaneously drive the connecting shaft to rotate. The connecting shaft can drive the mounting sleeve to rotate around the connecting shaft through the connecting spring. At this time, the fluff layer on the mounting sleeve can be driven to contact the outer wall of the upper end of the processing plate. The elastic deformation of the connecting spring is utilized. As the mounting sleeve and the fluff layer move along the vertical direction on the surface of the processing plate, the connecting spring can be bent. Finally, it is beneficial for the fluff layer to move along the vertical direction on the surface of the processing plate while rotating around the connecting shaft, so as to coat the water attached in the fluff layer on the surface of the vertically placed processing plate. The vertically placed processing plate after coating with water is convenient for the operator to grasp;

[0029] At the same time, when the fluff layer is separated from the processing plate, the fluff layer can be immersed in the water in the second storage box again, so that the fluff layer can absorb water again and is convenient for the next use;

[0030] 9. The threaded end of the mounting shaft is screwed with the mounting nut, so that the detachable connection of the mounting sleeve and the fluff layer on the mounting shaft is completed by the mounting nut. BRIEF DESCRIPTION OF DRAWINGS

[0044] Referring to Figure 2 , Figure 3 , Figure 5 , Figure 6The second storage box 39 is further provided with a coating mechanism 7 for coating water on the surface of the processing plate 2. The coating mechanism 7 comprises a connecting shaft 71, a connecting spring 72, a mounting shaft 73, a mounting sleeve 74 and a fluff layer 75. The connecting shaft 71 is integrally arranged at the end of the driven shaft 34 and penetrates through the second storage box 39. One end of the connecting spring 72 is welded to the end of the connecting shaft 71 away from the driven shaft 34. The mounting shaft 73 is welded to the end of the connecting spring 72 away from the connecting shaft 71. The mounting sleeve 74 is sleeved on the mounting shaft 73. The fluff layer 75 is bonded to the circumferential side of the mounting sleeve 74. At this time, the mounting sleeve 74 and the fluff layer 75 are rotatably connected to the connecting shaft 71. The fluff layer 75 is used to abut against the surface of the processing plate 2. The end of the mounting shaft 73 away from the connecting spring 72 is integrally provided with a threaded end 731. The threaded end 731 is threadedly connected with a mounting nut 732 for abutting against the end of the mounting sleeve 74.

[0045] Principle: First, the driving motor 36 drives the driving wheel 33 to rotate, thereby driving the transmission film 5 through the driven wheel 35 and the guide roller 41. Since the upper sides of the driving wheel 33 and the driven wheel 35 protrude from the opening slot 31, a part of the transmission film 5 passes above the workbench 3. Since the guide roller 41 delivers the transmission film 5 into the first storage box 4, the surface of the transmission film 5 after passing through the guide roller 41 will be attached with the liquid silica gel in the first storage box 4.

[0046] Meanwhile, the processing plate 2 to be laid with the TPU hot melt adhesive film is embedded in the second storage box 39 along the positioning arm 301. The end of the processing plate 2 is embedded in the positioning groove 391 in the second storage box 39. At this time, the driven shaft 34 can drive the connecting shaft 71 to rotate when rotating. The connecting shaft 71 can drive the mounting sleeve 74 to rotate around the connecting shaft 71 through the connecting spring 72. At this time, the fluff layer 75 on the mounting sleeve 74 can abut against the outer wall of the upper end of the processing plate 2. Since the connecting spring 72 has elastic deformation, as the mounting sleeve 74 and the fluff layer 75 move along the vertical direction on the surface of the processing plate 2, the connecting spring 72 can be bent. Finally, it is conducive to the fluff layer 75 to rotate around the connecting shaft 71 while moving along the vertical direction on the surface of the processing plate 2, thereby coating the water attached in the fluff layer 75 on the surface of the vertically placed processing plate 2.

[0047] The vertically placed processing plate 2 after coating water can be easily grabbed by the operator. After the grabbed processing plate 2 is placed on the workbench 3, the TPU hot melt adhesive film can be laid on the processing plate 2. At this time, since the surface of the processing plate 2 has water, the gap between the processing plate 2 and the TPU hot melt adhesive film is filled with water, so that air is lost. Atmospheric pressure can tightly press the TPU hot melt adhesive film on the processing plate 2. Finally, it is conducive to the stable laying of the TPU hot melt adhesive film on the processing plate 2.

[0048] When the TPU hot melt adhesive film is stably laid on the processing plate 2, the processing plate 2 can be embedded in the positioning rod 37, so that the processing plate 2 is stably placed below the transmission film 5 with the side with the TPU hot melt adhesive film upward, and then the lifting cylinder 63 and the rodless cylinder 62 are started, the lifting cylinder 63 drives the supporting arm 64 to move downward, and the rubber sleeve 66 on the lower side of the supporting arm 64 can press the transmission film 5 downward and tightly abut against the surface of the TPU hot melt adhesive film on the processing plate 2, and then the inductive cylinder drives the lifting cylinder 63 to translate along the transmission direction of the transmission film 5, at this time the rubber sleeve 66 can roll on the processing plate 2, and finally the part of the liquid silicone gel attached to the lower surface of the transmission film 5 is printed on the surface of the TPU hot melt adhesive film.

[0049] Compared with the manual operation of the operator to apply the liquid silicone gel to the surface of the TPU hot melt adhesive film by the scraper, since the liquid silicone gel attached to the transmission film 5 after passing through the guide wheel is relatively uniform, the liquid silicone gel printed on the TPU hot melt adhesive film by the transmission film 5 can also be relatively uniform, and finally it is beneficial to uniformly apply the liquid silicone gel on the TPU hot melt adhesive film.

[0050] The driving motor 36 continues to drive the transmission film 5, so that the transmission film 5 losing part of the liquid silicone gel is sent into the first storage box 4 again, and finally the transmission film 5 can be conveniently attached with new liquid silicone gel for the next operation.

[0051] The specific embodiment is only an explanation of the application, and is not a limitation of the application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the application, it is protected by the patent law.
