Technical Field
[0001] This utility model relates to the field of acrylic film production technology, specifically to a low-temperature resistant acrylic film thickness adjustment device. Background Technology
[0002] Low-temperature resistant acrylic film is a high-performance material made from acrylic using a special process. It maintains excellent flexibility and stability in low-temperature environments, effectively resisting the effects of cold climates. This film has ultra-high transparency, clearly showing objects behind it, and excellent adhesion, allowing it to firmly adhere to various material surfaces. Whether used for sealing building exteriors, protecting electronic devices, or connecting automotive parts, its low-temperature resistance ensures long-term stable operation in harsh conditions, providing reliable protection for various application scenarios.
[0003] Currently, when adjusting the thickness of acrylic film, the spacing between the pressure rollers used for thickness adjustment is usually fixed. This makes it inconvenient to adjust the spacing between the pressure rollers according to the needs of use to control the thickness of the acrylic film after adjustment, thus reducing its applicability. To address this, we propose a low-temperature resistant acrylic film thickness adjustment device. Utility Model Content
[0004] The purpose of this invention is to provide a low-temperature resistant acrylic film thickness adjustment device, which can adjust the spacing between the pressure rollers according to production needs to control the thickness of the acrylic film after adjustment, thereby improving applicability. Furthermore, the acrylic film thickness is gradually adjusted through multiple pressure rollers, which improves the uniformity of the acrylic film thickness after adjustment. This invention solves the problem that in current methods of adjusting the thickness of acrylic films, the spacing between the pressure rollers used for thickness adjustment is usually fixed, making it inconvenient to adjust the spacing between the pressure rollers according to the needs of use to control the thickness of the acrylic film after adjustment, thus reducing applicability.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature resistant acrylic film thickness adjustment device, comprising a U-shaped frame and pressure rollers. A first rotating frame and a second rotating frame are rotatably mounted on both sides of the U-shaped frame. Several pressure rollers are rotatably mounted inside the first and second rotating frames via rotating shafts at equal intervals. A power gear is fixedly sleeved at one end of each rotating shaft near the front surface of the U-shaped frame. A transmission gear is rotatably mounted on the front surface of both the first and second rotating frames between two adjacent power gears, and the transmission gear meshes with the power gear. A transmission shaft is rotatably mounted inside the U-shaped frame near the rear surface, and second bevel gears are fixedly connected to both ends of the transmission shaft. A first bevel gear is fixedly sleeved on the outer surface of the rotating shaft, and the second bevel gear meshes with the first bevel gear.
[0006] Preferably, a rotating motor is fixedly mounted on the rear surface of the U-shaped frame, and the end of the output shaft of the rotating motor is fixedly connected to one end of the rotating shaft near the rear surface of the U-shaped frame.
[0007] Preferably, the rotating motor is a geared motor.
[0008] Preferably, a fixing frame is fixedly installed at the middle position of the front and rear surfaces of the U-shaped frame, an electric cylinder is fixedly installed on the upper surface of the two fixing frames, and the output end of the two electric cylinders is fixedly connected to a connecting block through a connecting column. Rotating connecting rods are rotatably connected to both sides of the outer surface of the two connecting blocks, and the ends of the four rotating connecting rods are respectively rotatably connected to the front and rear surfaces of the first rotating frame and the second rotating frame near the lower surface.
[0009] Preferably, a sliding sleeve is fixedly installed at the bottom of the inner wall of both of the fixing frames, and the two connecting columns pass through the two sliding sleeves respectively.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, by setting up a U-shaped frame, pressure rollers, a first rotating frame, a second rotating frame, a power gear, a transmission gear, a rotating shaft, a transmission shaft, a first bevel gear, and a second bevel gear, achieves the goal of easily adjusting the spacing between the pressure rollers according to production needs, thereby controlling the thickness of the acrylic film after adjustment, improving applicability. Furthermore, the thickness of the acrylic film is gradually adjusted through multiple pressure rollers, improving the uniformity of the acrylic film thickness after adjustment. The first and second rotating frames are V-shaped, and adjacent pressure rollers are driven by the power gear and transmission gear to ensure... The pressure rollers rotate synchronously, and through the transmission shaft, the first bevel gear, and the second bevel gear, the pressure rollers on the first rotating frame and the second rotating frame rotate synchronously. The distance between the corresponding pressure rollers on the first rotating frame and the second rotating frame decreases from top to bottom, thus moving the acrylic sheet downwards. It is gradually squeezed by multiple pressure rollers to adjust the thickness of the acrylic sheet. By rotating the first rotating frame and the second rotating frame and adjusting the included angle between the first rotating frame and the second rotating frame, the distance between the pressure rollers on the first rotating frame and the second rotating frame can be controlled, thereby controlling the adjusted thickness of the acrylic sheet.
[0012] 2. This utility model achieves the effect of facilitating the rotation adjustment of the first and second rotating frames by setting up an electric cylinder, a fixed frame, a connecting column, a connecting block, and a rotating connecting rod. The electric cylinder drives the connecting block to rise and fall through the connecting column, and then drives the first and second rotating frames to rotate through the rotating connecting rod.
[0013] 3. By setting a sliding sleeve, this utility model plays a limiting and guiding role in the lifting and lowering of the connecting column, thereby improving the stability of the connecting column. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1-4 As shown, this utility model proposes a low-temperature resistant acrylic film thickness adjustment device, including a U-shaped frame 1 and pressure rollers 6. A first rotating frame 3 and a second rotating frame 5 are rotatably mounted on both sides inside the U-shaped frame 1, forming a V-shape between them. Several pressure rollers 6 are equidistantly mounted inside both the first rotating frame 3 and the second rotating frame 5 via a rotating shaft 8. The pressure rollers 6 inside the first rotating frame 3 and the second rotating frame 5 are distributed from top to bottom, with a one-to-one correspondence between them. The uppermost pressure rollers inside the first rotating frame 3 and the second rotating frame 5 are... The two ends of the rotating shaft 8 are rotatably connected to the U-shaped frame 1 via bearings. A power gear 7 is fixedly sleeved at one end of each rotating shaft 8 near the front surface of the U-shaped frame 1. A transmission gear 9 is rotatably installed on the front surface of the first rotating frame 3 and the second rotating frame 5 between two adjacent power gears 7, and the transmission gear 9 meshes with the power gear 7. A transmission shaft 4 is rotatably installed inside the U-shaped frame 1 near the rear surface, and a second bevel gear 12 is fixedly connected to both ends of the transmission shaft 4. A first bevel gear 11 is fixedly sleeved on the outer surface of the rotating shaft 8, and the second bevel gear 12 meshes with the first bevel gear 11.
[0021] A rotary motor 2 is fixedly mounted on the rear surface of the U-shaped frame 1. The end of the output shaft of the rotary motor 2 is fixedly connected to one end of the rotating shaft 8 near the rear surface of the U-shaped frame 1. The rotary motor 2 is a geared motor. The rotary motor 2 drives the rotating shaft 8 at the top inside the first rotating frame 3 to rotate, and drives the rotating shaft 8 at the top inside the second rotating frame 5 to rotate through the transmission shaft 4, the first bevel gear 11 and the second bevel gear 12. Fixed frames 10 are fixedly mounted at the middle positions of the front and rear surfaces of the U-shaped frame 1. Electric cylinders 13 are fixedly mounted on the upper surfaces of the two fixed frames 10, and the output ends of the two electric cylinders 13 are fixedly connected through the connecting column 14. There is a connecting block 16, and two connecting blocks 16 are rotatably connected to the two sides of the outer surface of each connecting block 16. The ends of the four rotating connecting rods 17 are respectively rotatably connected to the front and rear surfaces of the first rotating frame 3 and the second rotating frame 5 near the lower surface. The electric cylinder 13 drives the connecting block 16 to rise and fall through the connecting column 14, and then drives the first rotating frame 3 and the second rotating frame 5 to rotate through the rotating connecting rods 17. The bottom of the inner wall of each of the two fixed frames 10 is fixedly installed with a sliding sleeve 15, and the two connecting columns 14 pass through the two sliding sleeves 15 respectively. The sliding sleeves 15 play a limiting and guiding role in the rising and falling of the connecting column 14, improving the stability of the connecting column 14.
[0022] In use, the first rotating frame 3 and the second rotating frame 5 are V-shaped. Adjacent pressure rollers 6 are driven by a power gear 7 and a transmission gear 9 to make the pressure rollers 6 rotate synchronously. Through the transmission shaft 4, the first bevel gear 11 and the second bevel gear 12, the pressure rollers 6 on the first rotating frame 3 and the second rotating frame 5 rotate synchronously. The distance between the corresponding pressure rollers 6 on the first rotating frame 3 and the second rotating frame 5 decreases from top to bottom, so the acrylic sheet moves downward and is squeezed by multiple pressure rollers 6 in a step-by-step manner to adjust the thickness of the acrylic sheet. By rotating the first rotating frame 3 and the second rotating frame 5 and adjusting the included angle between the first rotating frame 3 and the second rotating frame 5, the distance between the pressure rollers 6 on the first rotating frame 3 and the second rotating frame 5 can be controlled to control the thickness of the acrylic sheet after adjustment.
