Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically a hot stamping device for polyester fabric. Background Technology

[0002] Currently, in the hot stamping process of polyester fabric, the traditional hot stamping equipment has a movable table for placing the fabric. When picking up or putting down the fabric, the movable table is pulled out from under the hot press device. When hot stamping, the movable table with the fabric is pushed under the hot press device so that the hot press device does not obstruct the top of the movable table, making it easier to pick up or put down the fabric. However, since the movement of the movable table needs to be manually controlled by the staff, it is relatively troublesome to use. Utility Model Content

[0003] The purpose of this invention is to provide a hot stamping device for polyester fabrics, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the polyester fabric hot stamping device includes a frame, the frame having a base, a body, and a head: The machine head is equipped with a retractable hydraulic cylinder. The output end of the hydraulic cylinder is provided with an end plate. An electric heating plate is provided below the end plate. The electric heating plate is fixed to the end plate by bolts. The end plate is provided with fixed frames at both ends. One fixed frame is equipped with an unwinding module and the other fixed frame is equipped with a winding module. The unwinding module is equipped with a hot stamping paper roll. Rotary rollers are provided on the two fixed frames and below the electric heating plate. A straight toothed rack is provided on the outer side of the fixed frame; A movable platform is slidably connected to the base, and toothed plates that mesh with a straight rack are respectively provided on both sides of the lower surface of the movable platform. A rotating shaft is installed on the base, and a main gear and a driven gear are provided on the rotating shaft. The main gear meshes with a spur rack, and the driven gear meshes with a toothed plate. Before the hot stamping foil comes into contact with the fabric on the movable table, one end of the movable table first abuts against the machine body, and the main gear disengages from the spur rack.

[0005] Preferably, fixing blocks are provided on both sides of the lower surface of the movable platform, and the fixing blocks are connected to the machine body through elastic elements.

[0006] Preferably, the upper surface of the movable platform has an annular groove.

[0007] Preferably, a fixing rod is provided on the upper surface of the end plate, and a through hole is provided on the machine head that is slidably connected to the fixing rod.

[0008] Preferably, the two sides of the upper surface of the movable platform are respectively set as arc shapes.

[0009] The beneficial effects of this utility model are: When this hot stamping device is in use, the hydraulic cylinder drives the end plate to move upward. Through the cooperation of the rack, main gear, driven gear, and gear plate, the movable table can move away from the machine body. When the end plate moves downward, the movable table can move closer to the machine body. Even after the movable table contacts the machine body, the end plate and the electric heating plate can still move vertically downward, thus realizing the hot stamping of fabric. The movement of the movable table in this device does not require manual control by the operator, thereby reducing the operator's operating pressure and improving the ease of use of the device.

Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 , 5As shown, both the unwinding module and the winding module include a fixing unit. The unwinding module also includes a pressure adjustment unit, and the winding module also includes a motor 33. The fixing unit may include a side plate 21, which is fixed to the outside of the fixing frame 8. A horizontal shaft 22 is rotatably connected to the side plate 21. The end of the horizontal shaft 22 furthest from the side plate 21 is provided with an external thread. The horizontal shaft 22 can be threadedly connected to the pressure cap 23. A limit plate 26 is provided on the outside of the horizontal shaft 22.

[0019] The pressure regulating unit in the unwinding module includes a cover 28 disposed on one side of the side plate 21. A fixing plate 27 is disposed at one end of the horizontal shaft 22, and the fixing plate 27 is located inside the cover 28. A stud 32 is threadedly connected to the cover 28, and a push plate 31 is disposed at the end of the stud 32. The stud 32 and the push plate 31 are fixedly connected. A pressure block 29 is disposed inside the cover 28, and an elastic pad 30 is disposed inside the cover 28 between the pressure block 29 and the push plate 31. When the stud 32 is in the cover... When the screw 28 is screwed inward, the push plate 31 can squeeze the elastic pad 30, and the elastic pad 30 squeezes the pressure block 29, thereby increasing the friction between the pressure block 29 and the fixed plate 27. When the horizontal shaft 22 rotates under the action of external force, if the external force is removed, the horizontal shaft 22 can also stop rotating quickly under the action of friction between the fixed plate 27 and the pressure block 29. The magnitude of the friction between the fixed plate 27 and the pressure block 29 can be controlled by controlling the screw 32's screwing distance in the cover 28.

[0020] The motor 33 in the unwinding module is fixed to the side of the side plate 21. The output end of the motor 33 is fixedly connected to the horizontal shaft 22 in the winding module. The motor 33 is controlled by a circuit board or PLC.

[0021] The roll 25 is located inside the hot stamping foil roll 24. When the hot stamping foil roll 24 is installed onto the unwinding module, the roll 25 containing the hot stamping foil roll 24 needs to be installed onto the horizontal shaft 22. Then, the pressure cap 23 is screwed onto the horizontal shaft 22. The pressure cap 23 continuously pushes the roll 25 to move until the roll 25 is fixed between the limiting plate 26 and the pressure cap 23. When tightening the pressure cap 23, the friction between the fixing plate 27 and the pressure block 29 can be increased by rotating the stud 32, making it difficult for the horizontal shaft 22 to rotate, thus facilitating the tightening of the pressure cap 23. After the pressure cap 23 is tightened, the stud 32 needs to be screwed out of the cover 28 a bit to avoid affecting the normal rotation of the horizontal shaft 22.

[0022] When installing the empty drum 25 onto the take-up module, the installation of the drum 25 onto the unwind module can be referenced. The motor 33 is equipped with a brake. When the motor 33 stops rotating, its output end will not rotate under the action of the brake, and the horizontal shaft 22 will not rotate, thus facilitating the tightening of the pressure cap 23.

[0023] After completing the installation of the hot stamping foil roll 24 and the empty roll 25, pull out one end of the hot stamping foil roll 24 and let it pass under the two rotating rollers 10. Then fix the pulled-out hot stamping foil 9 onto the empty roll 25. It can be fixed with tape. After the fixing is completed, the subsequent hot stamping work can be carried out.

[0024] like Figure 1-6 As shown, when hot stamping polyester fabric 19, the fabric 19 needs to be placed flat on the upper surface of the movable table 12 first, with the edge of the fabric 19 located in the annular groove 18. After the fabric 19 is placed, the hydraulic cylinder 4 is activated. The output end of the hydraulic cylinder 4 extends downward and pushes the end plate 5, electric heating plate 6, unwinding module, winding module, and fixing frame 8 downward. When the fixing frame 8 moves downward, it can drive the main gear 14 to rotate through the meshing of the rack 11 and the main gear 14. The driven gear 15 rotates synchronously with the main gear 14. The meshing of the driven gear 15 and the toothed plate 13 can drive the movable table 12 to move towards the machine body 2 on the base 1. When one end of the movable table 12 abuts against the machine body 2, the rack 11 disengages from the main gear 14, and at the same time, the elastic element 17 can keep the movable table 12 pressed against the machine body 2 through the fixing block 16. As the fixed frame 8 continues to move downwards, the position of the movable table 12 remains unchanged. When the hot stamping foil 9, located between the two rotating rollers 10, presses against the upper surface of the fabric 19, the electric heating plate 6 continues to move downwards, pressing the hot stamping foil 9 onto the fabric 19. The fabric 19 is pre-coated with a specific shaped adhesive. After the electric heating plate 6 heats it, the gold layer on the hot stamping foil 9 can be transferred to the fabric 19. After about 3 seconds of pressing, the hydraulic cylinder 4 starts to drive the electric heating plate 6 to move upwards. At the same time, the hot stamping foil 9 also moves upwards. The motor 33 starts, and the motor 33 drives the horizontal shaft 22 to rotate, and the used hot stamping foil 9 is wound up by the roll 25. Due to the friction between the fixed plate 27 and the pressure block 29, when the roll 25 on the take-up module rotates, the roll 25 on the unwind module has not yet rotated. Therefore, the hot stamping foil 9 located between the two rotating rollers 10 can be kept in a proper tension state. As the electric heating plate 6 moves upward, the two fixed frames 8 at both ends of the end plate 5 also move upward. Through the meshing of the spur rack 11 with the main gear 14 and the meshing of the driven gear 15 with the toothed plate 13, the movable table 12 can be driven away from the machine body 2. At this time, there is less obstruction above the movable table 12, which makes it easier to take out and put back the fabric 19.

[0025] The elastic element 17 is always in a stretched state. The elastic element 17 can be an elastic rope or a tension spring.

[0026] When the fixed rod 20 moves up and down, it can cooperate with the through hole on the machine head 3 to improve the stability of the end plate 5 when it moves up and down.

[0027] A pressure sensor is installed at the contact position between the output end of the hydraulic cylinder 4 and the end plate 5. By setting an appropriate pressure, the downward pressure of the electric heating plate 6 on the fabric 19 on the movable table 12 can be controlled. The hydraulic cylinder 4 is equipped with a power source and is controlled by a controller.

[0028] Motor 33 is a stepper motor 33, which is controlled by a controller.

[0029] The curved edge on the upper surface of the activity table 12 can prevent scratching the hot stamping foil 9.

[0030] Bolt 7 is welded to the upper surface of electric heating plate 6. Bolt 7 is equipped with a fixed retaining ring. When the retaining ring contacts the end plate 5, the bolt 7 is fixed to the end plate 5 by the connection between the nut and the bolt 7.

[0031] This hot stamping device is not only suitable for polyester fabrics, but also for a variety of other fabrics that can be hot stamped.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
