Abstract
Description
Technical Field
[0001] This utility model relates to the field of EVA glass film production and processing technology, and in particular to a high-temperature setting device for EVA glass film production. Background Technology
[0002] EVA glass film is widely used in laminated products such as architectural glass and automotive glass due to its good adhesion, weather resistance and optical properties. In its production process, high temperature setting is a key process. Precise temperature control is required to stabilize the molecular structure of the film and ensure that it is not easily deformed or delaminated in subsequent use.
[0003] The existing high-temperature setting equipment has the following shortcomings: 1. The clamping force of the film in traditional equipment is difficult to adjust. If it is too loose, the film will shift during the setting process. If it is too tight, the film will wrinkle and affect the flatness of the product. 2. Most of them use heating in one direction, which can easily cause temperature differences between the upper and lower surfaces of the film, resulting in uneven performance after setting. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. In this utility model, the clamping force can be flexibly adjusted to avoid film offset or wrinkling. The clamping plate moves up and down through the cooperation of bolts and handwheel. At the same time, the spring provides buffering force. The clamping strength can be precisely controlled by rotating the handwheel to prevent offset due to excessive looseness, and the elasticity of the spring can be used to avoid wrinkling due to excessive tightness, thus ensuring the flatness of the film.
[0017] 2. In this utility model, heating devices are provided at both the top and bottom of the setting box. The high-temperature steam generated by the steam generator is sent to the steam hood through the conveying pipe. Multiple nozzles heat the film from both the top and bottom sides simultaneously, reducing the temperature difference between the upper and lower surfaces and ensuring uniform performance after setting.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A high-temperature setting device for EVA glass film production includes a setting box 1, a door 2 connected to the front hinge of the setting box 1, a viewing window 3 embedded in the door 2, a placement device 4 fixedly connected to the inner wall of the setting box 1, L-shaped support legs 5 fixedly connected to both the left and right ends of the setting box 1, each L-shaped support leg 5 having a mounting hole 6, and a heating device 7 fixedly connected to both the upper and lower ends of the setting box 1.
[0029] In this embodiment, the placement device 4 includes a frame assembly 41, of which two frame assemblies 41 are provided. Four reinforcing rods 42 are fixedly connected to the inner sides of both frame assemblies 41. Bolts 43 are threadedly connected to the middle of each of the two frame assemblies 41. Handwheels 44 are fixedly connected to the upper ends of both bolts 43. Guide posts 45 are movably connected to the front and rear ends of the upper ends of both frame assemblies 41. Springs 46 are movably sleeved on the outer surfaces of both guide posts 45. Clamping plates 47 are fixedly connected to the lower ends of both guide posts 45. The lower ends of both bolts 43 are movably connected to the upper ends of both clamping plates 47 via bearings. The frame assembly 41 includes a connecting frame 411, with a threaded hole 412 at the middle of the upper end of the connecting frame 411, and movable holes 413 at the front and rear of the upper end of the connecting frame 411. The two connecting frames 411 are distributed in a left-right mirror image, and the outer surfaces of the two connecting frames 411 are respectively fixedly connected to the middle of the left and right inner walls of the shaping box 1. Bolts 43 are threaded into the threaded holes 412, and guide posts 45 are respectively movably sleeved in the corresponding movable holes 413. One end of the spring 46 is fixedly connected to the upper inner wall of the frame assembly 41, and the other end is fixedly connected to the upper end of the clamping plate 47.
[0030] Through the above scheme: rotating the handwheel 44 causes the bolt 43 to rotate in the threaded hole 412 of the connecting frame 411. The lower end of the bolt 43 pushes the clamping plate 47 down through the bearing. The guide post 45 slides along the movable hole 413 to ensure that the clamping plate 47 moves smoothly. At the same time, the spring 46 is stretched. Rotating the handwheel 44 in the opposite direction causes the spring 46 to rebound and drive the clamping plate 47 to reset, thereby realizing the adjustment of the tightness of the film. The two frame components 41 are reinforced by the reinforcing rod 42 to ensure structural stability.
[0031] In this embodiment, the heating device 7 includes a steam generator 71. A water inlet pipe 72 is fixedly installed on the upper part of the outer surface of the steam generator 71. A switch valve 73 is fixedly installed on the outer surface of the water inlet pipe 72. A temperature control knob 74 and an arc-shaped connecting frame 75 are fixedly connected to the upper and lower parts of the outer surface of the steam generator 71, respectively. An installation plate 76 is fixedly connected to the lower end of the arc-shaped connecting frame 75. A delivery pipe 77 is fixedly installed on the right end of the switch valve 73. A steam hood 78 is inserted and fixedly connected to the end of the delivery pipe 77 away from the steam generator 71. A plurality of nozzles 79 are provided at the lower end of the steam hood 78. The lower ends of the two installation plates 76 are fixedly connected to the upper left and lower right parts of the shaping box 1, respectively. The plurality of nozzles 79 are distributed at equal intervals.
[0032] Through the above scheme: when the switch valve 73 is opened, water enters the steam generator 71 through the water inlet pipe 72. The steam generator 71 generates high-temperature steam. The steam temperature is adjusted by the temperature control knob 74. The steam enters the steam hood 78 through the delivery pipe 77, and is then sprayed out by several equally spaced nozzles 79 to heat the film in the setting box 1. The arc-shaped connecting frame 75 and the mounting plate 76 fix the steam generator 71 on the setting box 1. The two heating devices 7 work together to achieve uniform heating of the upper and lower surfaces of the film, thereby improving the setting effect.
[0033] It should be noted that this utility model is a high-temperature setting device for EVA glass film production. In use, firstly, open the box door 2, place the EVA glass film between the frame components 41 of the placement device 4, turn the handwheel 44 to move the bolt 43 down, push the clamping plate 47 down along the guide post 45 and the movable hole 413, and stretch the spring 46 until the clamping plate 47 clamps the film. Close the box door 2, add water to the steam generator 71 through the water inlet pipe 72 and the switch valve 73, adjust the temperature control knob 74 to set the temperature, and the steam enters the steam hood 78 through the delivery pipe 77. The high-temperature steam is sprayed onto the upper and lower surfaces of the film by the nozzle 79 for setting. After setting, turn off the heating device 7, turn the handwheel 44 in the opposite direction, and the spring 46 rebounds to drive the clamping plate 47 to reset. Open the box door 2 and take out the film to complete the process.
