Description

Technical Field

[0001] This utility model relates to the field of PVC roll production, and in particular to a PVC roll embossing and demolding device. Background Technology

[0002] In PVC roll production, conveying is typically done using rollers. However, in complex production lines, multiple independent drives may exist between these rollers. This results in poor synchronization during the winding process, making the roll susceptible to stretching and tearing. Furthermore, because heating is required during roll forming, the roll often adheres to the roller surface, making it prone to tearing due to the rollers' pulling action. Adhesive-on-roll material is also difficult to demold, further impacting roll quality. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a PVC roll embossing demolding device.

[0004] This utility model is achieved by the following technical solution: a PVC roll embossing and demolding device, including a swing roller assembly and a fixed roller assembly mounted on a frame. The swing roller assembly includes a front swing roller group and a rear swing roller group. The front swing roller group and the rear swing roller group are respectively located on both sides of the fixed roller assembly and are symmetrically arranged with the fixed roller assembly as the center. The front swing roller group and the rear swing roller group swing back and forth on the frame, moving closer to or away from the fixed roller assembly.

[0005] The front swing roller assembly includes a front swing cylinder and a front swing arm. The front swing arm is rotatably connected to the frame, and the end of the front swing arm located on the upper part of the frame is rotatably connected to the front swing roller.

[0006] The front swing cylinder is mounted on the frame, and the drive shaft of the front swing cylinder is rotatably connected to one end of the front swing arm located at the lower part of the frame. The front swing cylinder drives the front swing arm to swing back and forth on the frame. When the front swing arm swings back and forth, the front swing roller moves closer to or further away from the fixed roller assembly.

[0007] The rear swing roller assembly includes a rear swing arm, a rear swing roller, and a rear swing cylinder. The rear swing arm is rotatably connected to the frame, and the rear swing roller is rotatably connected to one end of the rear swing arm located on the upper part of the frame.

[0008] The rear swing arm is located at one end of the lower part of the frame and is connected to the drive shaft of the rear swing cylinder. The rear swing cylinder is located on the frame and drives the rear swing arm to swing back and forth. When the rear swing arm swings back and forth, the rear swing roller moves closer to or further away from the fixed roller assembly.

[0009] The frame is provided with an upper mounting seat, which is located at the top of the frame. The front swing cylinder is rotatably connected to the upper mounting seat. One side of the upper mounting seat extends upward to form a front swing mounting seat. The front swing arm is rotatably connected to the front swing mounting seat. The upper mounting seat is provided with a mounting bracket. The fixed roller assembly is located on the mounting bracket. The front swing cylinder is located inside the mounting bracket and below the fixed roller assembly.

[0010] The frame is provided with a lower mounting base, which is located on one side of the frame along the height direction of the frame. A rotating lug is fixed on the end face of the lower mounting base, and the rear swing cylinder is rotatably connected to the rotating lug.

[0011] The fixed roller assembly includes a fixed roller, the end of which is rotatably connected to the mounting bracket, and the mounting bracket is provided with a drive motor for driving the fixed roller to rotate.

[0012] Compared to existing technologies, this invention involves the PVC roll being wound sequentially onto a front swing roller, a fixed roller, and a rear swing roller during operation. When the roll material on the fixed roller becomes stuck or when the drive of the fixed roller is inconsistent with the drive of other roller groups in the roll material production line, resulting in uneven roll material tension, one or both of the front and rear swing cylinders can be activated to adjust the distance between the roller on the side with uneven tension and the fixed roller, thereby alleviating the tension of the roll material. Specifically, when the tension is uneven, the front and rear swing cylinders correspondingly push the front and rear swing rollers towards the fixed roller. At this time, the roll material between the two sets of rollers bends downwards due to gravity, reducing the impact of uneven tension on the roll material at this point and also facilitating demolding.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] Reference Figure 1-3 A PVC roll embossing and demolding device includes a swing roller assembly 2 and a fixed roller assembly 3 mounted on a frame 1. The swing roller assembly 2 includes a front swing roller group 21 and a rear swing roller group 22, which are respectively located on both sides of the fixed roller assembly 3 and symmetrically arranged with the fixed roller assembly 3 as the center. The front swing roller group 21 and the rear swing roller group 22 swing back and forth on the frame 1, moving closer to or away from the fixed roller assembly 3. During use, the PVC roll is wound sequentially around the front swing roller group 21, the fixed roller assembly 3, and the rear swing roller group 22. When the roll on the fixed roller assembly 3 becomes stuck or when the drive of the fixed roller assembly 3 is inconsistent with the drive of other roller groups in the roll production line, resulting in uneven roll tension, the swing of the front swing roller group 21 and the rear swing roller group 22 can adjust the distance between the roller on the side with uneven tension and the fixed roller 31 to alleviate the tension of the roll. When the tension is uneven, the front swing roller group 21 and the rear swing roller group 22 swing towards the fixed roller 31. At this time, the roll material between the two roller groups bends downward due to gravity, so as to reduce the impact of uneven tension on the roll material at this point, and also facilitate demolding.

[0019] In this embodiment, the fixed roller assembly 3 includes a fixed roller 31, the end of which is rotatably connected to a mounting bracket 216. A drive motor is mounted on the mounting bracket 216 to drive the fixed roller 31 to rotate. Based on this, in this embodiment, the front swing roller assembly 21 includes a front swing cylinder 211 and a front swing arm 212. The front swing arm 212 is rotatably connected to the frame 1, and one end of the front swing arm 212 located on the upper part of the frame 1 is rotatably connected to a front swing roller 213. The front swing cylinder 211 is mounted on the frame 1, and its drive shaft is rotatably connected to the end of the front swing arm 212 located on the lower part of the frame 1. The front swing cylinder 211 drives the front swing arm 212 to reciprocate on the frame 1. When the front swing arm 212 reciprocates, the front swing roller 213 moves closer to or further away from the fixed roller assembly 3. To install the front swing cylinder 211, the frame 1 is provided with an upper mounting seat 214, which is located at the top of the frame 1. The front swing cylinder 211 is rotatably connected to the upper mounting seat 214. One side of the upper mounting seat 214 extends upward to form a front swing mounting seat 215. The front swing arm 212 is rotatably connected to the front swing mounting seat 215. The upper mounting seat 214 is provided with a mounting bracket 216, and the fixed roller assembly 3 is located on the mounting bracket 216. The front swing cylinder 211 is located inside the mounting bracket 216 and below the fixed roller assembly 3.

[0020] Correspondingly, the rear swing roller assembly 22 includes a rear swing arm 222, a rear swing roller 223, and a rear swing cylinder 221. The rear swing arm is rotatably connected to the frame 1, and the rear swing roller 223 is rotatably connected to one end of the rear swing arm 222 located on the upper part of the frame 1. The rear swing cylinder 221 is located on the frame 1 and drives the rear swing arm 222 to swing back and forth. When the rear swing arm 222 swings back and forth, the rear swing roller 223 moves closer to or away from the fixed roller assembly 3. To install the rear swing cylinder 221, a lower mounting seat 224 is provided on the frame 1. The lower mounting seat 224 is located on one side of the frame 1 along the height direction of the frame 1, and a rotating ear 225 is fixed on the end face of the lower mounting seat 224. The rear swing cylinder 221 is rotatably connected to the rotating ear 225.

[0021] When in use, the front swing roller 213 is pushed by the front swing cylinder 211, and the rear swing roller 223 is pushed by the rear swing cylinder 221. They will move closer to or further away from the fixed roller 31, so that their maximum stroke can be close to the fixed roller 31, that is, the roll material can be released as much as possible, so that the tension on the roll material in this area is minimized.

[0022] Compared to existing technologies, in this invention, the PVC roll material is sequentially wound around the front swing roller 213, the fixed roller 31, and the rear swing roller 223 during use. When the roll material on the fixed roller 31 becomes stuck or when the drive of the fixed roller 31 is inconsistent with the drive of other roller groups in the roll material production line, resulting in uneven roll material tension, one or both of the front swing cylinder 211 and the rear swing cylinder 221 are activated to adjust the distance between the roller on the side with uneven tension and the fixed roller 31, thereby relieving the tension of the roll material. That is, when the tension is uneven, the front swing cylinder 211 and the rear swing cylinder 221 correspondingly push the front swing roller 213 and the rear swing roller 223 to swing towards the fixed roller 31. At this time, the roll material between the two sets of rollers bends downward due to gravity, thereby reducing the impact of uneven tension on the roll material at this point, and also facilitating demolding.

[0023] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
