Description

Technical Field

[0001] This invention relates to the field of film shaping, and more particularly to an environmentally friendly, multifunctional decorative film anti-lateral shrinkage shaping system. Background Technology

[0002] Plastic film has been widely used in many fields and is an indispensable product in people's production and life. After the film is made into raw film material, heat setting is an important step in the process of eliminating internal stress, stabilizing surface tension and other technical indicators. The purpose is to eliminate internal stress in the film and increase dimensional stability. Existing heat setting equipment is not very effective and thermal stress is easily left inside the film.

[0003] To this end, Chinese invention patent CN114311440A discloses a novel environmentally friendly multifunctional decorative film anti-shrinkage heat setting device, including a housing and a fixing frame. The housing has an inlet on one side and an outlet on the other side. The fixing frame is set on the inner top wall of the housing. The lower ends of the fixing frame are respectively provided with downwardly extending connecting frames on both sides. The bottom of the connecting frames is provided with a pressure roller. The middle of the lower end of the fixing frame is provided with a horizontal connecting plate connected to an installation plate. A stretching roller is movably set on the installation plate. A first hot air pipe is provided on the upper side of the stretching roller to heat the upper side of the film. A second hot air pipe is provided on the lower side of the stretching roller to heat the lower side of the film. An external motor intermittently drives an external winding roller to rotate and wind up the film. The upper side of the film is heated inside the housing through the first hot air pipe, and the lower side of the film is heated inside the housing through the second hot air pipe, so that both sides of the film are heated, effectively eliminating its internal stress and achieving a good heat setting effect.

[0004] However, in actual use, we found that the stretching roller part used for movement in the above device is in hard contact with the film body, which can easily cause damage to the film. In addition, in the above process, an external hot air blower structure is required to achieve internal heating. The heated gas will be directly discharged to the outside, which not only increases the cost of electrical components, but also wastes heat. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly, multifunctional decorative film anti-lateral shrinkage shaping system. This shaping system uses a second rotating roller for the stretching part in conjunction with a spring to prevent film damage during movement. In addition, the entire forming process can be completed using only one motor, reducing the cost of electrical components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly, multifunctional decorative film anti-lateral shrinkage shaping system includes a housing with rectangular openings on its left and right inner walls. Multiple first rotating rollers are rotatably connected between the front and rear inner walls of the housing. A second rotating roller is located in the middle of the housing. A film body is mounted on the second rotating roller and the multiple first rotating rollers. A reciprocating movement mechanism is used to reciprocate the movement of an installation strip. The reciprocating movement mechanism includes an installation groove on the upper end of the installation strip, and an installation plate that can slide up and down is located within the installation groove. The lower end of the installation plate is elastically connected to the inner bottom of the installation groove via multiple springs. Two vertical plates are symmetrically fixedly connected to the upper end of the installation plate. The front and rear rotating shafts of the second rotating roller are rotatably connected to the two vertical plates, respectively. Movable blocks are fixedly connected to the front and rear sides of the installation strip. Two rotating shafts rotate between the upper and lower inner walls of the housing. Each of the two rotating shafts has a threaded layer, and the threaded portions of both rotating shafts penetrate the corresponding movable blocks and are threadedly connected to them. A drive mechanism is used to drive the reciprocating movement mechanism. A heating mechanism is used to heat the interior of the housing.

[0008] Preferably, the drive mechanism includes a mounting bracket installed on the rear side of the housing, on which a motor is mounted, and the upper ends of both rotating shafts extend to the outside.

[0009] Preferably, pulleys are installed on the outer sides of the upper ends of both shafts, and the two pulleys are connected by a drive belt.

[0010] Preferably, the motor is a servo motor with a variable rotation speed, and the output shaft of the motor is fixedly connected to the upper end of the rear rotating shaft.

[0011] Preferably, the heating mechanism includes a rectangular box fixedly connected to the upper end of the housing. A rectangular groove is provided on the left side of the rectangular box, and a piston plate that can slide left and right is provided in the rectangular groove. A rotating disk is installed on the upper end of the rotating shaft located on the front side. A connecting rod is rotatably connected to the upper end of the rotating disk at an eccentric position. The other end of the connecting rod is rotatably connected to the left side of the piston plate.

[0012] Preferably, a hollow plate is installed on the inner top of the shell, and multiple diversion holes are opened on the inner bottom of the hollow plate. Multiple heating wires are arranged inside the hollow plate. The right side space of the rectangular groove is connected to the inner bottom space of the shell through an air inlet pipe, and the right side space of the rectangular groove is connected to the interior of the hollow plate through an air outlet pipe.

[0013] Preferably, both the inlet pipe and the outlet pipe are equipped with one-way valves. The one-way valve in the inlet pipe allows the air to flow unidirectionally from the bottom space of the housing into the right side space of the rectangular groove, and the one-way valve in the outlet pipe allows the air to flow unidirectionally from the right side space of the rectangular groove into the hollow plate.

[0014] Preferably, two pairs of electric telescopic rods are symmetrically installed on the inner top of the housing, and each pair of electric telescopic rods has a pressure plate fixedly connected to its telescopic end, and each pressure plate has a sponge layer at its lower end.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows:

[0016] 1. Equipped with a turntable, piston plate, air inlet pipe, air outlet pipe, and one-way valve, it achieves hot air circulation inside the housing using only a motor as the drive source, reducing the use of electrical components and avoiding heat loss to the outside. In addition, the setting of multiple diversion holes ensures uniform temperature inside the housing, guaranteeing the effect of film heat setting.

[0017] 2. The start of the motor will also cause the second rotating roller to move up and down through the reciprocating movement mechanism, so that the film body inside the shell is stretched and relaxed repeatedly. This allows the film body to undergo tensioning and heat setting, preventing the film body from shrinking, effectively eliminating residual internal stress in the film body, and improving the quality of the film.

[0018] 3. A spring section is also provided. By using the spring, the force acting on the film body is reduced and automatically buffered when the second rotating roller moves up and down. This can effectively prevent the second rotating roller from exerting too much force on the film body and damaging it. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Reference Figure 1-5 An environmentally friendly multifunctional decorative film anti-lateral shrinkage shaping system includes a housing 1. Rectangular openings 2 are provided on the left and right inner walls of the housing 1. Multiple first rotating rollers 16 are rotatably connected between the front and rear inner walls of the housing 1. A second rotating roller 23 is provided in the middle of the housing 1. A film body 3 is provided on the second rotating roller 23 and the multiple first rotating rollers 16.

[0028] As one embodiment of the present invention, it also includes a reciprocating moving mechanism for reciprocating up and down the mounting strip 19. The reciprocating moving mechanism includes a mounting groove 30 opened at the upper end of the mounting strip 19. A mounting plate 7 that can slide up and down is provided in the mounting groove 30. The lower end of the mounting plate 7 is elastically connected to the inner bottom of the mounting groove 30 through multiple springs 9. Two vertical plates 22 are symmetrically fixedly connected to the upper end of the mounting plate 7. The front and rear rotating shafts of the second rotating roller 23 are respectively rotatably connected to the two vertical plates 22. The front and rear sides of the mounting strip 19 are fixedly connected to the moving block 20. Two rotating shafts 10 rotate between the upper and lower inner walls of the housing 1. Both rotating shafts 10 are provided with threaded layers 21. The threaded layer 21 is a threaded part similar to a reciprocating lead screw. With the unidirectional rotation of the threaded layer 21, the moving block 20 can be driven to move up and down reciprocally. The threaded layer 21 part of the two rotating shafts 10 passes through the corresponding moving block 20 and is threadedly connected to the corresponding moving block 20.

[0029] As one embodiment of the present invention, it also includes a drive mechanism for driving a reciprocating motion mechanism. The drive mechanism includes a mounting bracket 4 installed on the rear side of the housing 1. A motor 5 is mounted on the mounting bracket 4. The upper ends of two rotating shafts 10 extend to the outside. Pulleys 6 are installed on the outer side of the upper ends of the two rotating shafts 10. The two pulleys 6 are connected to the motor 5 via a transmission belt 8. The motor 5 is a servo motor with a variable rotation speed. The output shaft of the motor 5 is fixedly connected to the upper end of the rotating shaft 10 on the rear side.

[0030] In one embodiment of the present invention, a heating mechanism is also included. This heating mechanism heats the interior of the housing 1. The heating mechanism includes a rectangular box 13 fixedly connected to the upper end of the housing 1. A rectangular groove 14 is provided on the left side of the rectangular box 13. A piston plate 17, which can slide left and right, is disposed within the rectangular groove 14. A rotating disk 11 is mounted on the upper end of a rotating shaft 10 located on the front side. A connecting rod 12 is rotatably connected to the upper eccentric part of the rotating disk 11. The other end of the connecting rod 12 is rotatably connected to the left side of the piston plate 17. A hollow plate 27 is installed on the inner top of the housing 1. Multiple diversion holes 28 are provided on the inner bottom of the hollow plate 27. Multiple heating wires 29 are disposed within the hollow plate 27. A temperature sensor can also be installed inside the housing 1 to cooperate with the heating wire 29, so as to sense the internal temperature of the housing 1, thereby activating the heating wire 29 when the internal temperature drops and deactivating the heating wire 29 when the temperature is high. The right side space of the rectangular groove 14 is connected to the inner bottom space of the housing 1 through the air inlet pipe 15, and the right side space of the rectangular groove 14 is connected to the inside of the hollow plate 27 through the air outlet pipe 18. One-way valves are installed in both the air inlet pipe 15 and the air outlet pipe 18. The flow direction of the one-way valve in the air inlet pipe 15 is one-way from the bottom space of the housing 1 to the right side space of the rectangular groove 14, and the flow direction of the one-way valve in the air outlet pipe 18 is one-way from the right side space of the rectangular groove 14 to the hollow plate 27.

[0031] In one embodiment of the present invention, two pairs of electric telescopic rods 24 are symmetrically installed on the inner top of the housing 1. Each pair of electric telescopic rods 24 is fixedly connected to a pressure plate 25 at its telescopic end. Each pressure plate 25 has a sponge layer 26 at its lower end.

[0032] In this invention, during use, multiple electric telescopic rods 24 are first activated to extend, thereby causing the two pressure plates 25 to move down. Then, by utilizing the sponge layer 26 part in cooperation with the corresponding first rotating roller 16, the film body 3 located in the housing 1 is limited.

[0033] Then, start the motor 5 and the heating wire 29. After the heating wire 29 is started, the internal temperature of the hollow plate 27 will rise. After the motor 5 is started, the front shaft 10 will rotate through the use of two pulleys 6. The rotation of the front shaft 10 will cause the rotating disk 11 to rotate. Through the use of the connecting rod 12, the piston plate 17 will move left and right. When the piston plate 17 moves left and right, it will replenish the gas from the housing 1 through the air inlet pipe 15. When the piston plate 17 moves right, it will force the gas into the hollow plate 27 through the air outlet pipe 18. Finally, the gas will be heated and diverted and then re-enter the housing 1, realizing the gas circulation inside the housing 1. This gas circulation can realize the circulation heating, avoid the heat being discharged to the outside and wasted, and through the setting of multiple diversion holes 28, the temperature inside the housing 1 is made uniform, ensuring the effect of film heat setting.

[0034] The use of two pulleys 6 causes the two rotating shafts 10 to rotate synchronously. The synchronous rotation of the two rotating shafts 10, through the threaded layer 21, allows the two moving blocks 20 to move up and down synchronously. The synchronous up and down reciprocating motion of the two moving blocks 20 allows the mounting strip 19 to move up and down, and finally causes the second rotating roller 23 to move up and down, causing the film body 3 inside the housing 1 to be stretched and relaxed repeatedly. This allows the film body 3 to undergo tensioning and heat setting and relaxation heat setting, preventing the film body 3 from shrinking, effectively eliminating residual internal stress in the film body 3, improving the quality of the film. Furthermore, due to the setting of the spring 9, it can effectively avoid the situation where the second rotating roller 23 exerts excessive force on the film body 3, which could damage the film body 3.

[0035] After heat setting is completed, multiple electric telescopic rods 24 are activated to retract, thereby causing the two pressure plates 25 to move upwards. An external motor is controlled to drive the external take-up roller to rotate, and the heat-set film body 3 is wound up, so that the unheat-set film body 3 enters the housing 1, thus performing cyclic heat setting.
