Description

Technical Field

[0001] The present invention relates to the technical field of film crushing, and particularly to a rotary crusher for recycling and regenerating waste films. Background Art

[0002] Recycling and crushing of waste films refers to the process of using a crusher to crush used plastic films, such as food packaging films, into smaller pieces or particles. In this process, waste films are first collected and sorted to remove impurities and foreign objects. Then, they are fed into the crusher, which uses rotating blades to break the films into smaller sizes. Plastic films used in some individually packaged products or plastic bags are relatively scattered one by one. When crushing these plastic films, in order to improve the crushing efficiency, a conveyor belt is generally used for feeding. However, when feeding with a conveyor belt, it is impossible to timely control the amount of film fed. When the films inside the crusher are not broken in time and accumulate too much, and the conveyor belt continues to feed, it will cause the crusher to be overloaded, easily resulting in motor overload, increased wear of transmission components, and even possible equipment failure and damage. Moreover, a large number of unbroken films are squeezed against each other, unable to be fully crushed, resulting in uneven sizes of the crushed materials and failing to achieve the expected crushing effect. At the same time, the films are light in weight, so during the crushing process, it is not easy for the films to enter the inside of the crushing rollers, thereby causing the overall crushing progress to be slow and affecting the working efficiency.

[0030] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification

[0031] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments

[0033] Example 1

[0034] Reference Figures 1 - 3 、 Figure 5 、 Figure 8 and Figure 10 This is the first embodiment of the present invention. This embodiment provides a rotary crusher for recycling waste films. The rotary crusher for recycling waste films includes a main body assembly 100, which includes a housing 101, a blanking plate 102, and a baffle 102-1. The blanking plate 102 is fixed to one side of the housing 101, and the baffle 102-1 is fixed to the top of the blanking plate 102. The number of baffles 102-1 is two, which are respectively fixed to both sides of the top of the blanking plate 102.

[0035] The blanking plate 102 is inclined. The feeding conveyor belt is arranged on one side of the blanking plate 102. The film conveyed by the conveyor belt will fall onto the top of the blanking plate 102, and the film will be conveyed into the housing 101 through the blanking plate 102 to complete the feeding.

[0036] The top of the blanking plate 102 is divided into three conveying channels by two baffles 102-1, and the films falling onto the top of the blanking plate 102 are respectively located in the three conveying channels.

[0037] A material blocking assembly 200 is arranged on one side of the housing 101, and includes a fixed frame 201a, a blocking block 201b, a rotating column 201c, a first fixed shaft 201d, a gear 201e, and a toothed plate 201f. The fixed frame 201a is fixed to one side of the housing 101. The blocking block 201b is located inside the fixed frame 201a. The rotating column 201c is rotatably connected inside the fixed frame 201a. The first fixed shaft 201d is fixed inside the blocking block 201b. A first spiral groove 201c-1 is formed on the rotating column 201c, and the first fixed shaft 201d slides inside the first spiral groove 201c-1. The gear 201e is fixed to the top end of the rotating column 201c, and the toothed plate 201f is located on one side of the gear 201e.

[0038] The above are all in three groups, corresponding to the three conveying channels respectively. The blocking block 201b is movably connected inside the fixed frame 201a. The toothed plate 201f and the gear 201e on the side close to the support plate 202f, that is, the right side of the housing 101, are meshed. The middle toothed plate 201f is not meshed with the gear 201e, but the distance is relatively close. The toothed plate 201f on the left side of the housing 101 is far from the gear 201e. The three toothed plates 201f are connected and fixed by a fixed rod.

[0039] When there is too much film accumulated inside the outer shell 101, at this time, the tooth plate 201f on the right side will move to the right and drive the gear 201e to rotate. The rotating column 201c is driven to rotate by the gear 201e. At this time, the first fixed shaft 201d will slide in the first spiral groove 201c-1. Through the cooperation of the two, the stopper 201b is driven to move downward, so that the stopper 201b on the right side moves downward into the conveying channel on the right side and blocks the film inside the channel, making it impossible to enter the outer shell 101. In this way, the amount of film feeding can be reduced, so that the crushing roller can fully crush the accumulated film, thus avoiding the situation that the size of the crushed material is uneven.

[0040] At this time, the middle tooth plate 201f meshes with the gear 201e, and the left tooth plate 201f approaches the gear 201e. After reducing the feeding, if the film accumulated inside the outer shell 101 still cannot be broken in time and continues to accumulate upward, at this time, the tooth plate 201f will continue to move, and the middle tooth plate 201f will drive the gear 201e to rotate, so that the middle stopper 201b moves downward and blocks the film inside the middle conveying channel. In this way, the amount of film feeding can be further reduced until the film on the top of the blanking plate 102 is completely blocked and intercepted, and the feeding into the outer shell 101 is stopped.

[0041] A stabilizing frame is fixed on the top of the outer shell 101. The fixing rod is movably connected to the stabilizing frame. The two cooperate to support and position the tooth plate 201f to prevent the tooth plate 201f from shifting when moving. A first connecting block is fixed on the top of the stabilizing frame, a second connecting block is fixed on the top of the tooth plate 201f, and a third spring is fixed between the first connecting block and the second connecting block.

[0042] When the film accumulated inside the outer shell 101 is broken, the restriction on the tooth plate 201f will be released. At this time, a thrust is applied to the second connecting block through the third spring, and the tooth plate 201f is driven to move through the second connecting block. In this way, the tooth plate 201f can be reset, and the tooth plate 201f drives the gear 201e to rotate in the reverse direction, and then the stopper 201b can be reset upward.

[0043] The material pressing assembly 300 is arranged inside the outer shell 101 and includes a pressing plate 301a, a fixed sleeve 301b, a fixed column 301c and a first spring 301d. The pressing plate 301a is located inside the outer shell 101. The fixed sleeve 301b is fixed on the top of the pressing plate 301a. The fixed column 301c is inserted into the fixed sleeve 301b, and both ends of the first spring 301d are fixed to the pressing plate 301a and the fixed column 301c respectively.

[0044] When the fixed column 301c moves downward, it drives the pressing plate 301a to move downward through the first spring 301d, and presses the film above the crushing roller downward through the pressing plate 301a, so that the film can quickly enter the inside of the crushing roller, thereby improving the overall crushing efficiency.

[0045] When the crushing roller fails to crush the film in time, it will cause excessive accumulation of the film. At this time, when the pressing plate 301a contacts the film, it will not be able to press the film downward, and then the pressing plate 301a cannot continue to move downward. As the fixed column 301c continues to move downward, it will squeeze the first spring 301d and move within the fixed sleeve 301b.

[0046] Embodiment 2

[0047] Refer to Figures 1 - 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0048] Specifically, the outer shell 101 is rotatably connected with a rotating wheel 202a, a pull rope 202b is wound around the outside of the rotating wheel 202a, and both ends of the pull rope 202b are fixed to the rotating wheel 202a and the toothed plate 201f respectively.

[0049] When the rotating wheel 202a rotates, it will wind up the pull rope 202b, so as to drive the toothed plate 201f to move through the pull rope 202b.

[0050] Specifically, a positioning column 202c is fixed to the top of the pressing plate 301a, a second fixed shaft 202d is fixed to one side of the positioning column 202c, a second spiral groove 301c-1 is formed in the fixed column 301c, and the second fixed shaft 202d slides in the second spiral groove 301c-1. A slider 202e is fixed in the rotating wheel 202a, and a sliding groove 301c-2 is formed in the fixed column 301c, and the slider 202e slides in the sliding groove 301c-2.

[0051] Through the cooperation of the slider 202e and the sliding groove 301c-2, the rotating wheel 202a is connected to the fixed column 301c, so that the fixed column 301c can drive the rotating wheel 202a to rotate, and at the same time, it can also move up and down in the rotating wheel 202a.

[0052] When the fixed column 301c moves downward in the fixed sleeve 301b, the second fixed shaft 202d will slide in the second spiral groove 301c-1, and the two cooperate to drive the fixed column 301c to rotate, so that the fixed column 301c can drive the rotating wheel 202a to rotate.

[0053] Specifically, a support frame 203a is fixed to one side of the fixed sleeve 301b. A clamping block 203b is arranged inside the support frame 203a. A second spring 203c is fixed to one side of the clamping block 203b. A clamping groove 301c-3 is formed on the fixed column 301c, and the number of the clamping grooves 301c-3 is three.

[0054] The clamping groove 301c-3 is annular. One side of the clamping block 203b is inclined and extends into the fixed sleeve 301b. When the fixed column 301c moves downward in the fixed sleeve 301b, it will contact the inclined surface of the clamping block 203b and push the clamping block 203b to move into the support frame 203a. When the lowermost clamping groove 301c-3 coincides with the clamping block 203b, at this time, a thrust is applied to the clamping block 203b through the second spring 203c, and the clamping block 203b is engaged with the clamping groove 301c-3. Through the cooperation of the two, the fixed column 301c can be locked, so that the fixed column 301c cannot move upward by the thrust of the first spring 301d. Furthermore, the rotating wheel 202a can be kept in the state of winding up the pull rope 202b, so as to avoid the situation that the toothed plate 201f will reset.

[0055] The three clamping grooves 301c-3 correspond to the three toothed plates 201f. As the moving stroke of the fixed column 301c downward in the fixed sleeve 301b increases, the clamping block 203b will be sequentially engaged with the upper two clamping grooves 301c-3.

[0056] Specifically, a force-receiving block 204a is fixed to the top of the clamping block 203b. An extrusion block 204b is arranged on one side of the force-receiving block 204a. A connecting column 204c is fixed to one side of the extrusion block 204b. One side of the extrusion block 204b is inclined, and the inclined surface of the extrusion block 204b contacts the force-receiving block 204a.

[0057] When the connecting column 204c moves, it will drive the inclined surface of the extrusion block 204b to extrude the force-receiving block 204a, and drive the clamping block 203b to move through the force-receiving block 204a. In this way, the clamping block 203b can be separated from the clamping groove 301c-3, and the restriction on the fixed column 301c can be released. Furthermore, the fixed column 301c can be reset.

[0058] A plurality of stabilizing rods are fixed to the top of the pressing plate 301a. The connecting column 204c is movably connected inside the stabilizing rods, which is used for supporting and positioning the connecting column 204c.

[0059] Specifically, a support block 204d is fixed to the inner wall of the outer shell 101. A force-receiving plate 204e is rotatably connected to one side of the support block 204d. A top block 204f is fixed to one side of the support block 204d. The top block 204f contacts the force-receiving plate 204e and supports the force-receiving plate 204e.

[0060] The force-bearing plate 204e is rotatably connected to the support block 204d through a rotating shaft. The force-bearing plate 204e is inclined and is supported by the top block 204f so that it cannot rotate downward. When the connecting column 204c moves downward, it will contact the inclined force-bearing plate 204e and drive the extrusion block 204b to move under the extrusion of the force-bearing plate 204e.

[0061] When the connecting column 204c moves upward and contacts the force-bearing plate 204e, it will push the force-bearing plate 204e to rotate upward, and at this time the connecting column 204c will not move.

[0062] Embodiment 3

[0063] Refer to Figures 1 - 10 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0064] Specifically, a material blocking plate 302 is fixed on one side of the pressing plate 301a, and a diversion plate 303 is fixed inside the housing 101. The diversion plate 303 is inclined.

[0065] When the pressing plate 301a presses the film downward, the material blocking plate 302 can block the film entering the inside of the housing 101 to prevent it from falling on top of the pressing plate 301a. The falling film is guided by the diversion plate 303 so that it can fall between the two crushing rollers.

[0066] Specifically, a support frame 304 is fixed on the top of the housing 101. A cylinder 305 is arranged inside the support frame 304. The output end of the cylinder 305 is rotatably connected to the fixed column 301c through a bearing.

[0067] The support frame 304 is used to support the cylinder 305, and the cylinder 305 is used to drive the fixed column 301c to move up and down.

[0068] Specifically, a support plate 202f is fixed on one side of the housing 101. A guide wheel 202g is arranged on the top of the support plate 202f. The pull rope 202b is wound around the outside of the guide wheel 202g.

[0069] The guide wheel 202g is used to guide and position the pull rope 202b.

[0070] Specifically, the main body assembly 100 further includes a crushing roller 103 and a discharging mechanism 104. The crushing roller 103 is located inside the housing 101, and the discharging mechanism 104 is arranged on one side of the housing 101.

[0071] The crushing roller 103 is used to crush the film, and the discharging mechanism 104 is used to discharge the crushed film. This is the prior art and will not be elaborated in this solution.

[0072] In summary, the rotary crusher for recycling waste films of our invention has the following effects:

[0073] 1. It can press the film and force-feed the film to improve the crushing efficiency.

[0074] 2. When the film accumulates inside the crusher, it can automatically intercept the amount of the fed material.

[0075] 3. It can adaptively intercept the number of films according to the amount of film accumulation inside the crusher.

[0076] 4. After the interception, it can slowly increase the amount of film feeding according to the amount of crushed and discharged accumulated film.

[0077] During use, the feeding conveyor belt is arranged on one side of the blanking plate 102. The film conveyed by the conveyor belt will fall onto the top of the blanking plate 102, and the film is conveyed into the interior of the housing 101 through the blanking plate 102 to complete the feeding. Then, the air cylinder 305 is started to drive the fixed column 301c to move downward. When the fixed column 301c moves downward, the pressing plate 301a is driven to move downward through the first spring 301d, and the film above the crushing roller is pressed downward through the pressing plate 301a, so that the film can quickly enter the interior of the crushing roller, thereby improving the overall crushing efficiency.

[0078] When the crushing roller fails to crush the film in time, it will cause excessive film accumulation. At this time, when the pressing plate 301a contacts the film, it will not be able to press the film downward, and further the pressing plate 301a cannot continue to move downward. As the fixed column 301c continues to move downward, the first spring 301d will be squeezed and move within the fixed sleeve 301b. At this time, the second fixed shaft 202d slides in the second spiral groove 301c-1, and the two cooperate to drive the fixed column 301c to rotate. In this way, the fixed column 301c can drive the rotating wheel 202a to rotate. When the rotating wheel 202a rotates, the pull rope 202b will be wound up, and thus the toothed plate 201f can be driven to move through the pull rope 202b.

[0079] At this time, the right toothed plate 201f will move to the right and drive the gear 201e to rotate. The gear 201e drives the rotating column 201c to rotate. At this time, the first fixed shaft 201d will slide in the first spiral groove 201c-1, and the two cooperate to drive the block 201b to move downward, so that the right block 201b moves downward into the right conveying channel and blocks the film inside the channel, preventing it from entering the housing 101, so as to reduce the amount of film feeding, enable the crushing roller to fully crush the accumulated film, and thus avoid the situation of uneven size of the crushed material.

[0080] At this time, the middle tooth plate 201f meshes with the gear 201e, and the tooth plate 201f on the left side approaches the gear 201e. After reducing the feeding, if the film accumulated inside the housing 101 still cannot be broken in time and continues to accumulate upward, at this time, the tooth plate 201f will continue to move, and the middle tooth plate 201f will drive the gear 201e to rotate, causing the middle stopper 201b to move downward and blocking the film inside the middle conveying channel. In this way, the amount of film feeding can be further reduced until the film on the top of the blanking plate 102 is completely blocked and intercepted, and the feeding into the housing 101 is stopped.

[0081] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
