Description

Technical Field

[0001] This application relates to the field of crushing equipment technology, and in particular to a thin film crusher. Background Technology

[0002] During the production of thin films, it is unavoidable to generate edge material and substandard waste. To avoid waste, this waste is usually crushed and reused by a thin film shredder. A thin film shredder is a device that crushes thin films into pieces of a specified size through cutting and extrusion. In operation, the thin film is simply fed into the shredder's inlet for crushing. After crushing, the film pieces are transported to a subsequent recycling unit. However, edge material and some waste with low structural strength often break during the feeding process, leading to material breakage. Conventional thin film shredders lack corresponding monitoring measures, requiring manual observation. This is cumbersome and labor-intensive for large-scale recycling and crushing. Utility Model Content

[0003] The purpose of this application is to provide a film crusher, which aims to improve the problem of requiring manual monitoring and judgment of the material breakage status of the film crusher in related technologies, and to improve the automation level and ease of use of the film crusher.

[0004] This application provides a film crusher, including a frame and a crushing mechanism disposed within the frame. The frame has a feed inlet and a feeding mechanism disposed on the frame. The feeding mechanism includes an adjustable clamping structure disposed at the feed inlet and a monitoring and guiding structure disposed on one side of the adjustable clamping structure. The monitoring and guiding structure includes a feed support rod, a guiding component disposed on the feed support rod, and a monitoring component. The guiding component includes a feed swing arm hinged to the feed support rod and a feed guide wheel rotatably connected to the feed swing arm, the feed guide wheel facing the feed inlet. The monitoring component includes a material sensor disposed on the feed support rod and an alarm light, the material sensor facing between the feed guide wheel and the feed inlet.

[0005] Furthermore, the feeding swing arm is hinged with a tension spring, one end of which is hinged to the feeding swing arm, and the other end of which is hinged to the feeding support rod.

[0006] Furthermore, the material sensor has a connecting block, and the material sensor is detachably connected to the feed support rod through the connecting block.

[0007] Furthermore, the material sensor is provided with a telescopic support column facing the feed swing arm, and the telescopic support column is rotatably connected to a support wheel, which abuts against the feed swing arm.

[0008] Furthermore, the adjustable clamping structure includes an inlet support base disposed at the inlet, a fixed side assembly, and a movable side assembly; the fixed side assembly includes a driving member and a fixed guide wheel disposed on the driving member; the movable side assembly includes a fixed rod, a movable swing arm hinged to the fixed rod, a movable guide wheel rotatably connected to the movable swing arm, and a first adjusting rod for driving the movable swing arm; the movable guide wheel and the fixed guide wheel are disposed opposite to each other, and there is a material passage space between the movable guide wheel and the fixed guide wheel.

[0009] Furthermore, the first adjusting rod is slidably connected to the fixed rod, and the first adjusting rod has a first pressing block facing the movable swing arm, the first pressing block abutting against or disengaging from the movable swing arm; the first adjusting rod is sleeved with a compression spring.

[0010] Furthermore, the movable side assembly also includes a second adjusting rod for cooperating with the first adjusting rod. The second adjusting rod is disposed on the side of the movable guide wheel away from the first adjusting rod, and the second adjusting rod abuts against or disengages from the movable guide wheel.

[0011] Furthermore, a soundproof cover is provided on the outside of the frame.

[0012] The beneficial effects of this application are:

[0013] 1. A film crusher according to this application, wherein an adjustable clamping structure is provided at the feed inlet, and a monitoring and guiding structure is provided on one side of the adjustable clamping structure; when the film is introduced, the film passes through the feed swing rod and feed guide wheel of the guiding component, and then enters the feed inlet through the adjustable clamping component and is conveyed to the crushing mechanism for crushing. When the film passes through the guide wheel and the adjustable clamping structure, the film is detected by a material sensor. When the material sensor can detect the film, it indicates that the film crusher is operating normally. When the material sensor cannot detect the film, it indicates that a breakage or other abnormality has occurred. The material sensor issues an alarm through an alarm light, so that the operator can be notified of the abnormality in time and take action. The entire monitoring process does not require manual execution, saving time and effort and effectively improving the level of automation.

[0014] 2. A film crusher according to this application includes a tension spring installed between the feeding swing rod and the feeding support rod. The tension spring applies a continuous tension to the feeding swing rod, allowing the film to have a certain tension when passing the feeding guide wheel, thus ensuring the film remains stable during feeding and improving the feeding smoothness. Simultaneously, a telescopic support column is installed in the material sensor, with its support wheel abutting against the feeding swing rod. The support wheel supports the feeding swing rod, increasing its support capacity. Combined with the tension spring, this further improves the stability and smoothness of the feeding process.

[0015] 3. A film crusher according to this application, by setting an adjustable clamping structure, uses a fixed side component as a drive source, and a movable side component in conjunction with the fixed side to form a material passage space. On the one hand, the film can be clamped by the fixed side component and the movable side component to ensure the feeding direction of the film, so as to facilitate its processing by the crushing mechanism. On the other hand, the size of the material passage space can be adjusted by moving the movable side component to adapt to films of different thicknesses, thereby improving the versatility and ease of use of the film crusher.

The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0026] Reference Figure 1 as well as Figure 2 This application provides a film crusher, including a frame 1 and a crushing mechanism disposed within the frame 1. The frame 1 has a feed inlet and also includes a feeding mechanism 2 disposed within the frame 1. The feeding mechanism 2 includes an adjustable clamping structure 21 disposed at the feed inlet and a monitoring and guiding structure 22 disposed on one side of the adjustable clamping structure 21. During operation, the film material passes sequentially through the monitoring and guiding structure 22 and the adjustable clamping structure 21 before entering through the feed inlet. After entering through the feed inlet, the film is fed into the crushing mechanism for crushing. During this process, the monitoring and guiding structure 22 can monitor and provide feedback on the film's feeding status, while the adjustable clamping structure 21 can adapt to films of different specifications and guide the film.

[0027] Specifically, the base supports the various structures, the feed inlet is located above the base, and wheels are installed below the base for easy movement. A soundproof cover 11 is installed on the outside of the frame 1 to effectively block the noise generated by the crushing mechanism during operation. The crushing mechanism is located inside the frame 1 and is used to crush the film. The crushing mechanism is existing technology and can be purchased; its specific structure and principle will not be described in detail here.

[0028] Reference Figure 2 as well as Figure 3 The adjustable clamping structure 21 includes a feed support 211 disposed at the feed inlet, a fixed side assembly 212, and a movable side assembly 213. The feed support 211 is fixedly connected above the feed inlet and has a cavity communicating with the feed inlet. The feed support 211 is used to cooperate with the fixed side assembly 212 and the movable side assembly 213 to limit the film material, so that the film can enter the crushing mechanism along a preset path.

[0029] In this embodiment, the fixed side assembly 212 includes a driving member and a fixed guide wheel 2121 disposed on the driving member. The driving member is a motor, and the fixed guide wheel 2121 is disposed on the output shaft of the driving member. The fixed guide wheel 2121 is located on one side of the feed support 211 in the width direction. Driven by the motor, the fixed guide wheel 2121 will rotate continuously to cooperate with the moving side assembly 213 to transport the film to the feed support 211 and the crushing mechanism.

[0030] Reference Figure 2 , Figure 3 as well as Figure 4 The movable side assembly 213 includes a fixed rod 2131, a movable swing arm 2132 hinged to the fixed rod 2131, a movable guide wheel 2133 rotatably connected to the movable swing arm 2132, and a first adjusting rod 2134 for driving the movable swing arm 2132. The fixed rod 2131 is used to mount the movable swing arm 2132 and is fixedly connected to the frame 1 and located on one side of the feed support 211. One end of the movable swing arm 2132 is hinged to the side of the fixed rod 2131 near the feed support 211. This end of the movable swing arm 2132 is installed by a threaded connection to facilitate rotation and limit movement. The feed guide wheel 2222 is rotatably connected to the other end of the movable swing arm 2132. The movable guide wheel 2133 and the fixed guide wheel 2121 are arranged opposite to each other, and there is a material passage space between the movable guide wheel 2133 and the fixed guide wheel 2121. When the film passes through the material feeding space, it will abut against the fixed guide wheel 2121 and the movable guide wheel 2133. When the fixed guide wheel 2121 rotates, it can drive the film to move, and the movable guide wheel 2133 rotates with the movement of the film.

[0031] The first adjusting rod 2134 is used to adjust the distance between the movable guide wheel 2133 and the fixed guide wheel 2121, thereby adjusting the size of the material passage space. In this embodiment, the first adjusting rod 2134 is slidably connected to the fixed rod 2131. It can be understood that the first adjusting rod 2134 can be slidably connected to the fixed rod 2131 by means of interference fit, or the first adjusting rod 2134 can be slidably connected to the fixed rod 2131 by means of threaded connection. The first adjusting rod 2134 has a first pressing block 21341 facing the movable swing arm 2132. The first pressing block 21341 abuts against or disengages from the movable swing arm 2132, and the first adjusting rod 2134 is sleeved with a compression spring, which abuts against the first pressing block 21341. The first guide wheel is provided with a protrusion for cooperating with the first pressing block 21341.

[0032] When the size of the material passage space needs to be adjusted, loosening the movable swing arm 2132 allows it to rotate. Sliding the first adjusting rod 2134 causes the first adjusting rod 2134 to move the first pressing block 21341 slightly closer to or further away from the movable guide wheel 2133. The first pressing block 21341 can then drive the movable guide wheel 2133 to swing, or limit the movable guide wheel, thereby adjusting the distance between the movable guide wheel 2133 and the fixed guide wheel 2121, thus adjusting the material passage space. Finally, locking the movable swing arm 2132 completes the fixation of the movable guide wheel 2133.

[0033] Furthermore, to increase the stability of adjustment and support, the moving side assembly 213 also includes a second adjusting rod 2135 for cooperating with the first adjusting rod 2134. The second adjusting rod 2135 is located on the side of the moving guide wheel 2133 away from the first adjusting rod 2134, and the second adjusting rod 2135 abuts against or disengages from the moving guide wheel 2133. The structure of the second adjusting rod 2135 is the same as that of the first adjusting rod 2134. A fixed seat is provided on the side of the moving guide wheel 2133 away from the first adjusting rod 2134, and the second adjusting rod 2135 is slidably connected to the fixed seat and is fitted with a compression spring. The position of the other end of the moving guide wheel 2133 can be adjusted and limited and supported by the second adjusting rod 2135, thereby ensuring the stability of the moving guide wheel 2133 during operation.

[0034] Reference Figure 2 , Figure 3 as well as Figure 5 The monitoring and guiding structure 22 includes a feed support rod 221, a guide assembly 222 disposed on the feed support rod 221, and a monitoring assembly 223. The feed support rod 221 is fixedly connected to the frame 1 and located on one side of the adjustable support structure, and the feed support rod 221 is vertically arranged. The guide assembly 222 includes a feed swing rod 2221 hinged to the feed support rod 221 and a feed guide wheel 2222 rotatably connected to the feed swing rod 2221. The feed guide wheel 2222 faces the feed inlet. To ensure smooth feeding, a tension spring is hinged to the feed swing rod 2221. One end of the tension spring is hinged to the feed swing rod 2221, and the other end of the tension spring is hinged to the feed support rod 221. The tension spring can apply a continuous tension to the feed swing rod 2221. When the film passes through the feed guide wheel 2222, it can make the film have a certain tension, thereby ensuring that the film remains stable during feeding and improving the smoothness of feeding.

[0035] The monitoring component 223 includes a material sensor 2231 and an alarm light 2232 disposed on the feed support rod 221. The material sensor 2231 faces the feed guide wheel 2222 and the feed inlet, and is electrically connected to the alarm light 2232. In this embodiment, the material sensor 2231 has a connecting block, and the material sensor 2231 is detachably connected to the feed support rod 221 via a threaded connection through the connecting block. Simultaneously, the material sensor 2231 is provided with a telescopic support column 2233 facing the feed swing rod 2221. The telescopic support column 2233 includes a fixed end and a telescopic end, which are slidably connected to the fixed end and connected by a spring. A support wheel is rotatably connected to the telescopic support column 2233, and the support wheel abuts against the feed swing rod 2221.

[0036] By setting up a material sensor 2231 and an alarm light 2232, when the film continuously enters the material passage space from the feed guide wheel 2222, the material sensor 2231 can detect the presence of the film, thus indicating that the crusher is operating normally. When the film breaks, the material sensor 2231 can no longer detect the presence of the film. At this time, the material sensor 2231 will sound an alarm through the alarm light 2232, and the operator can then know that there is a material shortage fault in the crusher. By setting up a telescopic support column 2233 and a support wheel, the telescopic support column 2233, under the action of a spring, supports the lower end of the feed swing rod 2221 through the support wheel, thereby increasing the positional stability of the feed swing rod 2221 and ensuring the smooth feeding of the film.
