Description

Technical Field

[0001] This utility model relates to the field of material recycling technology, specifically a recycling mechanism for removing waste material before slitting a membrane roll. Background Technology

[0002] During the film roll slitting process, unusable edge material is often generated at the ends of the film roll. This edge material is automatically recycled to the edge material crushing system during the operation of the film roll slitting device. As described in the text entitled "An Edge Material Recycling System" in Chinese Patent Publication No. CN112173826A, the edge material generated after cutting is fed into the crusher through a traction component. The crusher crushes the edge material and then conveys it to the feed end of the extruder through a fan and hose. There is no need for operators to repeatedly send the wound edge material to the second floor.

[0003] However, during storage before slitting, the outer surface of the membrane roll is easily contaminated by dust. Since contamination on the outer periphery of the roll usually only involves the surface ring, removing this contamination only requires cleaning the outer ring. Contamination at the ends of the roll, however, often affects the entire roll. Although the contaminated end material is removed as scrap during slitting, in actual slitting operations, dust from the ends is blown onto the clean inner membrane surface as the roll unfolds. Therefore, before actual slitting, the contaminated waste material at the ends of the roll is removed. However, this necessitates an additional recycling and crushing process in existing technologies to recover and crush the removed waste roll, a problem that urgently needs to be addressed. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a recycling mechanism for waste material removed before film roll slitting, which can simultaneously recycle the waste material removed before film roll processing and the edge material during film roll processing, without the need for an additional recycling and crushing process for the waste material removed before film roll processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A recycling mechanism for removing waste material before film roll slitting includes a frame and a film roll feeding roller mounted on the frame. A waste material feeding roller is also mounted on the frame. The waste material feeding roller rotates at the same speed as the film roll feeding roller through a matching gear set. A negative pressure dust collection disc connected to a negative pressure machine is coaxially sleeved at one end of the waste material feeding roller.

[0007] As a further embodiment of this utility model: the path between the waste material on the waste material feeding roller and the film roll feeding roller is the waste material conveying path, and the first roller and the second roller are arranged side by side on the waste material conveying path, and the first roller and the second roller can perform a clamping action to clamp the waste material on the waste material conveying path.

[0008] As a further embodiment of this utility model: a mounting frame is installed on the frame, the first roller is rotatably fitted on the mounting frame, the fixed seat of the second roller is slidably fitted with the mounting frame through a guide rod, and a compression spring is sleeved on the guide rod to compress the second roller toward the first roller, so as to form the clamping motion action.

[0009] As a further embodiment of this utility model: the negative pressure suction holes on the negative pressure suction disk are arranged on the disk surface adjacent to the waste material feeding roller, and the negative pressure suction holes are arranged in several groups distributed in a ring around the axis of the negative pressure suction disk.

[0010] As a further embodiment of this utility model: both the waste material feeding roller and the film roll feeding roller are arranged horizontally, and the corresponding gear set includes a first corresponding gear and a second corresponding gear that are coaxially fixed to the waste material feeding roller and the film roll feeding roller respectively, and both the first corresponding gear and the second corresponding gear mesh with the connecting gear.

[0011] As a further embodiment of this utility model: the waste feeding roller is horizontally arranged at the lower part of the frame, and a loading platform that can slide along the axial direction of the waste feeding roller is provided directly below the waste feeding roller. From the perspective of the sliding direction of the loading platform, the bottom of the loading platform is close to the ground, and the side walls of the loading platform are inclined to facilitate the rolling transfer of the cut waste roll to the platform surface.

[0012] As a further improvement of this utility model, the loading platform is slidably fitted onto the shaft of the optical axis guide rod via a linear bearing.

[0013] As a further improvement of this utility model: the table surface of the loading platform is detachably fixed with a pad, and the side wall of the pad is smoothly connected to the inclined side wall of the loading platform.

[0014] As a further improvement of this utility model, the waste material feeding roller is an air-expanding shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. A waste feed roller is installed on the frame. After the waste material at the end of the film roll is cut off, the film roll is mounted on the film roll feed roller, and the waste roll is mounted on the waste feed roller. At this time, a negative pressure dust suction disc is installed on the waste feed pipe to remove dust during the unwinding process of the waste feed roller without interfering with the film roll slitting. In addition, since the outer diameter of the film roll and the waste roll are the same, when the film roll feed roller and the waste feed roller rotate at the same speed, they will drive the film roll and the waste roll to unwind at the same speed. This allows the traction mechanism to effectively and synchronously pull the edge material and waste material generated after the film roll is slitted to the crushing mechanism, eliminating the need for a separate crushing process for the waste material cut off before film processing.

[0017] 2. In the initial stage of device startup, the waste material on the waste material feeding roller can be connected to the edge material on the film roll feeding roller along the waste material conveying path between the waste material feeding roller and the film roll feeding roller. This allows the starting end of the waste material to move along with the edge material on the film roll, eliminating the need for manual traction of the starting end to the traction mechanism in the initial stage, thus improving the ease of use of the device. Furthermore, a first roller and a second roller are arranged side-by-side on the waste material conveying path. These rollers can clamp the waste material on the conveying path, preventing the waste material from shaking under the negative pressure suction disc before it moves to the traction mechanism, thereby preventing interference with the film roll cutting process in the initial stage.

[0018] 3. A feeding platform is set below the waste feeding roller. The waste roll can roll along the inclined surface of the feeding platform to the platform surface, and the platform surface can slide along the axial direction of the waste feeding roller, so as to facilitate the convenient feeding of the waste roll on the waste feeding roller.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0026] The specific structure of this utility model is as follows: Figure 1-4 As shown, its main structure includes a frame 10, a film roll feeding roller 11 mounted on the frame 10, and a waste material feeding roller 20. The waste material feeding roller 20 rotates at the same speed as the film roll feeding roller 11 via a matching gear set 50. In use, the film roll after waste material cutting is mounted on the film roll feeding roller 11, and the waste material roll generated from cutting is mounted on the waste material feeding pipe 20. Since the outer diameters of the film roll and the waste material roll are the same, when the film roll feeding roller 11 and the waste material feeding roller 20 rotate at the same speed, they will drive the film roll and the waste material roll to unwind at the same speed. This allows the traction mechanism to effectively and synchronously traction the edge material and waste material generated after film roll cutting to the crushing mechanism, eliminating the need for a separate crushing process for the waste material cut off before film processing. In addition, a negative pressure dust collection disc 60 connected to a negative pressure machine is coaxially sleeved at one end of the waste material feeding roller 20, which can remove dust during the unwinding process of the waste material feeding roller 20 and will not interfere with the slitting of the film roll, effectively preventing the dust generated during the unwinding process of the waste roll from affecting the film roll.

[0027] Furthermore, such as Figure 1As shown, the waste conveying path is the path between the waste material on the waste material feeding roller 20 and the film roll feeding roller 11. A first roller 32 and a second roller 33 are arranged side-by-side along this waste material conveying path, and the first roller 32 and the second roller 33 can perform clamping movements to hold the waste material on the waste material conveying path. In the initial stage of device startup, the starting end of the waste material on the waste material feeding roller 20 can be connected to the edge material on the film roll feeding roller 11 along the waste material conveying path between the waste material on the waste material feeding roller 20 and the film roll feeding roller 11. This allows the starting end of the waste material to move along with the edge material on the film roll, eliminating the need for manual pulling of the starting end of the waste material to the traction mechanism in the initial stage, thus improving the ease of use of the device. Furthermore, since the first roller 32 and the second roller 33 are arranged side by side on the above-mentioned waste conveying path, the first roller 32 and the second roller 33 can perform a clamping action to clamp the waste on the waste conveying path. At the beginning of the waste, as the edge material moves to the front of the traction mechanism, the shaking force of the waste under the action of the negative pressure dust collection disc 60 is blocked, thereby preventing the waste from interfering with the film roll slitting in the initial stage.

[0028] Specifically, such as Figure 2 As shown, a mounting bracket 31 is installed on the frame 10. The first roller 32 is rotatably fitted on the mounting bracket 31. The fixed seat of the second roller 33 is slidably fitted with the mounting bracket 31 through a guide rod 35. A compression spring 34 is sleeved on the guide rod 35 to compress the second roller 33 towards the first roller 32, thereby forming a clamping motion. Using the compression spring 34 as the clamping power mechanism has the advantages of convenient operation and low cost. In specific implementation, the clamping motion of the first roller 32 and the second roller 33 can also be achieved by using a linear power source such as a cylinder.

[0029] Based on the above, such as Figure 3 As shown, the negative pressure suction holes on the negative pressure suction disk 60 are located on the disk surface adjacent to the waste material feeding roller 20, and are arranged in several groups in a ring around the axis of the negative pressure suction disk 60. In actual implementation, the outer end face of the waste roll with accumulated dust is facing the negative pressure suction disk 60. Through the several groups of negative pressure suction holes arranged in a ring around the negative pressure suction disk 60, comprehensive dust removal and discharge of the outer end of the waste roll can be achieved.

[0030] Based on the above, such as Figure 1As shown, both the waste material feed roller 20 and the film roll feed roller 11 are horizontally arranged. The corresponding gear set 50 includes a first corresponding gear and a second corresponding gear, which are coaxially fixed to the waste material feed roller 20 and the film roll feed roller 11, respectively. Both the first and second corresponding gears mesh with the connecting gear, thereby achieving the same speed rotation of the waste material feed roller 20 and the film roll feed roller 11. Of course, in actual implementation, the connecting gear may not be provided or may be provided in at least two sets. Alternatively, belt drives or other methods can be used to achieve the same speed rotation of the waste material feed roller 20 and the film roll feed roller 11.

[0031] It is worth mentioning that, in order to facilitate the installation of the waste roll on the waste feed roller 20, such as Figure 1 and Figure 4 As shown, the waste feed roller 20 is horizontally arranged at the lower part of the frame 10, and a loading platform 42 that can slide along the axial direction of the waste feed roller 20 is provided directly below the waste feed roller 20. From the perspective of the sliding direction of the loading platform 42, the bottom of the loading platform 42 is close to the ground, and the side walls of the loading platform 42 are inclined to facilitate the rolling transfer of the cut waste roll to the platform surface of the loading platform 42. After that, the loading platform 42 moves along the axial direction of the waste feed roller 20, so that the waste roll can be sleeved on the waste feed roller 20, thereby realizing the convenient installation of the waste roll.

[0032] Furthermore, such as Figure 4 As shown, the loading platform 42 is slidably fitted onto the shaft of the optical axis guide rod 41 via a linear bearing 43, which effectively reduces the frictional resistance during the sliding process of the loading platform 42.

[0033] In addition, such as Figure 4 As shown, the table surface of the feeding platform 42 is detachably fixed with a pad 44, and the side wall of the pad 44 is smoothly connected to the inclined side wall of the feeding platform 42, which can realize the height adjustment of the feeding platform 42 to adapt to the feeding of waste rolls of different diameters.

[0034] Based on the above, the waste feed roller 20 is an air-expanding shaft, which can quickly fix the waste roll to the waste feed roller 20, further improving the convenience of waste roll installation.

[0035] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
