DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Embodiment 1

[0025] Reference Figs. 1-3 A film recycling device, comprising a crushing unit 1, a rack 2, a clamping unit 3, an auxiliary roller unit 4, and a recycling frame 5 for collecting paper core barrels; the crushing unit 1 is located on one side of the rack 2; the recycling frame 5 is located below the auxiliary roller unit 4; the clamping unit 3 is connected to the rack 2; the auxiliary roller unit 4 is slidingly connected to the rack 2; the auxiliary roller unit 4 is provided with an openable and closable recycling notch 41;

[0026] The clamping unit 3 is used for clamping the film roll and rotating with the film roll to continuously feed the film into the crushing unit 1 for crushing.

[0027] The auxiliary roller unit 4 is used for supporting the film roll, matching the position of the paper core on the film roll with the clamping unit 3, and enabling the paper core to enter the recycling frame 5 from the recycling gap 41.

[0028] The recycling device is mainly used for crushing and recycling the film roll that fails to pass the detection. The finished product after the film is made and wound on the paper core is called a film roll. The crushing unit 1 can refer to the waste material crusher in CN211890953U, and the specific structure is not described in detail here.

[0029] In the embodiment, the specific working process of the recycling device is as follows: the worker places the film roll on the auxiliary roller unit 4, starts the clamping unit 3, and the clamping unit 3 clamps the two ends of the paper core in the film roll; then, the worker pulls the free end of the film on the film roll to the crushing unit 1, starts the crushing unit 1, and the crushing unit 1 pulls and crushes the film. In this process, the film on the film roll is pulled by the crushing unit 1, so that the film roll rotates on the clamping unit 3, thereby continuously moving the film on the film roll to the crushing unit 1; when the film is completely separated from the paper core, the worker starts the auxiliary roller unit 4, and the auxiliary roller unit 4 moves to the two ends of the rack 2, so that the middle part of the auxiliary roller unit 4 forms the recycling gap 41; then, the clamping unit 3 is started to loosen the paper core, and the paper core enters the recycling frame 5 from the recycling gap 41.

[0030] It should be noted that after the worker places the film roll on the auxiliary roller unit 4, the auxiliary rollers 42 are close to or away from each other to adjust the height of the paper core in the axial direction of the film roll, so that the clamping unit 3 can abut against the center of the paper core. Secondly, the paper core enters the recycling frame 5 through the recycling gap 41, without the need to take the paper core from the side, thereby reducing the workload of the worker.

[0031] Preferably, the clamping unit 3 comprises clamping modules symmetrically arranged on the rack 2; the clamping module comprises a driving assembly 31 and a clamping head 32 for pressing the paper core; the driving assembly 31 is connected to the rack 2; and the clamping head 32 is rotationally connected to the power output end of the driving assembly 31.

[0032] In the embodiment, the driving assembly 31 is a cylinder, more preferably a guide rod cylinder, and a suitable type of guide rod cylinder is selected according to the weight of the film roll. The clamping head 32 is rotatably connected to the power output end of the driving assembly 31 through a bearing. The more specific working process of the clamping unit 3 is as follows: after the worker places the film roll on the auxiliary roller 42, the driving assembly 31 drives the clamping head 32 to approach the film roll and abuts against the end of the paper core barrel. The two sides of the rack 2 are each provided with a clamping module, so that the two ends of the paper core barrel are respectively abutted by the two clamping heads. When the film on the film roll is continuously drawn out, the film roll rotates together with the clamping head 32, so that the film can be continuously drawn out. By clamping the film roll in this way, the film roll can be stably rotated, and the paper core barrel can be easily separated from the clamping unit 3 and enter the recycling frame 5.

[0033] Preferably, one end of the clamping head 32 close to the paper core barrel is a tapered end 321. In order to reduce the positioning difficulty of the clamping head 32 and the paper core barrel, the end of the clamping head 32 is provided in a conical shape, so that the clamping head 32 can be easily inserted into the paper core barrel and abut against the end of the paper core barrel.

[0034] Preferably, the auxiliary roller unit 4 comprises an auxiliary roller 42, a mounting seat 43, and a driving module 44 for driving the two auxiliary rollers 42 to approach or move away from each other; the driving module 44 is connected to the rack 2; the mounting seat 43 is slidably connected to the rack 2; the two ends of the auxiliary roller 42 are rotatably connected to the two mounting seats 43, respectively; the two auxiliary rollers 42 are symmetrically arranged on the two sides of the clamping unit 3; the recycling gap 41 is formed between the two auxiliary rollers 42; and the two auxiliary rollers 42 approach or move away from each other to open or close the recycling gap 41.

[0035] In the embodiment, the auxiliary roller 42 is slidably connected to the rack 2 through the mounting seat 43, and the number of auxiliary rollers 42 is two. The two auxiliary rollers 42 are symmetrically arranged on the two sides of the clamping unit 3. The driving module 44 drives the mounting seats 43 on the same side of the two auxiliary rollers 42 to approach each other, thereby driving the two auxiliary rollers 42 to approach each other. At this time, the worker can place the film roll on the auxiliary rollers 42 and drive the clamping unit 3 to clamp the film roll. When it is necessary to transport the paper core barrel to the recycling frame 5, the driving module 44 drives the mounting seats 43 on the same side of the two auxiliary rollers 42 to move away from each other, thereby driving the two auxiliary rollers 42 to move away from each other, so that the recycling gap 41 is formed between the two auxiliary rollers 42. The clamping unit 3 releases the paper core barrel, and the paper core barrel can fall into the recycling frame 5 from the recycling gap 41. After the paper core barrel falls into the recycling frame 5, the two auxiliary rollers 42 approach each other, so that the next film roll can be placed on the two auxiliary rollers 42.

[0036] Secondly, the two auxiliary rollers 42 can approach or move away from each other, which can meet the use of film rolls with different diameters.

[0037] Preferably, the driving module 44 comprises a motor 441 and a reversible screw 442; the motor 441 is connected to the rack 2; the reversible screw 442 is rotatably connected to the rack 2; the power output end of the motor 441 is connected to one end of the reversible screw 442; and the two ends of the reversible screw 442 are respectively threadedly connected to the two mounting seats 43 on the same side.

[0038] In the embodiment, the reversible screw 442 is provided with a reversible thread at each end and a smooth rod in the middle. The two ends of the reversible screw 442 are respectively threadedly connected to the mounting seats 43 on the same side of the two auxiliary rollers 42. When the motor 441 drives the reversible screw 442 to rotate in one direction, the two mounting seats 43 will move closer to or farther away from each other, thereby driving the two auxiliary rollers 42 to move closer to or farther away from each other.

[0039] Preferably, the rack 2 is provided with a sliding rail 11; and the mounting seat 43 is slidably connected to the rack 2 through the sliding rail 11.

[0040] In the embodiment, by providing the sliding rail 11, the situation that the auxiliary roller 42 deviates and jams during movement can be avoided, and the movement of the mounting seat 43 driving the auxiliary roller 42 is more smooth.

[0041] Preferably, the rack 2 is provided with a feeding plate 12; the feeding plate 12 is located below the auxiliary roller unit 4; and the feeding plate 12 is used to convey the paper core barrel falling in the auxiliary roller unit 4 into the recycling frame 5.

[0042] In the embodiment, after the auxiliary roller unit 4 is started and the middle part of the auxiliary roller unit 4 forms the recycling gap 41, the paper core barrel enters the feeding plate 12 from the recycling gap 41 and rolls into the recycling frame 5 from the feeding plate 12, avoiding the paper core barrel from directly falling into the recycling frame 5, reducing the impact force of the paper core barrel falling, and preventing the paper core barrel from flying out of the recycling frame 5.

[0043] Preferably, the feeding plate 12 is provided with a baffle 121 on each side. The baffle 121 can prevent the paper core barrel from separating from the feeding plate 12 from the side of the feeding plate 12 and failing to enter the recycling frame 5 when rolling on the feeding plate 12.

[0044] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
