Description

Technical Field

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

[0002] Waste film recycling and shredding refers to the process of breaking used plastic films, such as food packaging films, into smaller fragments or particles through a shredder. In this process, the waste films are first collected and sorted to remove impurities and foreign matter, and then put into the shredder. The shredder breaks the film into smaller sizes through rotating blades. The plastic films or plastic bags used in some independent packaging products are scattered one by one. When these plastic films are broken, in order to improve the breaking efficiency, conveyor belts are generally used for feeding, and the conveyor belts are used for feeding. When the film inside the crusher is not broken in time and accumulates too much, and the conveyor belt is still feeding, the load on the crusher will be too large, which may easily cause motor overload and increased wear of transmission parts, and may even cause equipment failure and damage. In addition, a large number of films that are not broken in time squeeze each other and cannot be fully broken, resulting in uneven size of the broken materials and failing to achieve the expected crushing effect. At the same time, the weight of the film is relatively light, so during the crushing process, the film is not easy to enter the crushing roller, which leads to slow overall crushing progress and affects work efficiency.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1 Reference Figure 1-Figure 3 , Figure 5 , Figure 8 and Fig.10 , which is the first embodiment of the present invention, and this embodiment provides a rotary crusher for recycling and regenerating waste films. The rotary crusher for recycling and regenerating waste films includes a main component 100, including a shell 101, a blanking plate 102 and a baffle 102-1. The blanking plate 102 is fixed to one side of the shell 101, and the baffle 102-1 is fixed to the top of the blanking plate 102. There are two baffles 102-1, which are respectively fixed on both sides of the top of the blanking plate 102.

[0031] The blanking plate 102 is inclined, and the feeding conveyor belt is set on one side of the blanking plate 102. The film conveyed by the conveyor belt will fall to the top of the blanking plate 102, and the film will be transported to the inside of the shell 101 through the blanking plate 102, thereby completing the feeding.

[0032] The top of the blanking plate 102 is divided into three conveying channels by two baffles 102 - 1 , and the film dropped to the top of the blanking plate 102 is respectively located in the three conveying channels.

[0033] The material blocking assembly 200 is arranged on one side of the shell 101, and includes a fixed frame 201a, a block 201b, a rotating column 201c, a first fixed shaft 201d, a gear 201e and a tooth plate 201f. The fixed frame 201a is fixed to one side of the shell 101, the block 201b is located in the fixed frame 201a, the rotating column 201c is rotatably connected to the fixed frame 201a, the first fixed shaft 201d is fixed in the block 201b, the rotating column 201c is provided with a first spiral groove 201c-1, the first fixed shaft 201d slides in the first spiral groove 201c-1, the gear 201e is fixed to the top of the rotating column 201c, and the tooth plate 201f is located on one side of the gear 201e.

[0034] The above-mentioned three groups correspond to three conveying channels respectively. The block 201b is movably connected with the fixed frame 201a. The tooth plate 201f close to the support plate 202f side, that is, the right side of the shell 101, is engaged with the gear 201e. The middle tooth plate 201f is not engaged with the gear 201e, but the distance is relatively close. The tooth plate 201f on the left side of the shell 101 is far away from the gear 201e. The three tooth plates 201f are connected and fixed by fixing rods.

[0035] When there is too much film accumulated inside the shell 101, the toothed plate 201f on the right will move to the right and drive the gear 201e to rotate, and the gear 201e will drive 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 cooperation of the two will drive the block 201b to move downward, so that the block 201b on the right moves downward to the conveying channel on the right, and blocks the film inside the channel, so that it cannot enter the shell 101, thereby reducing the amount of film loading, allowing the crushing roller to fully crush the accumulated film, thereby avoiding uneven size of the crushed material.

[0036] At this time, the middle tooth plate 201f is meshed with the gear 201e, and the left tooth plate 201f is close to the gear 201e. After reducing the feeding, if the accumulated film inside the shell 101 still cannot be broken in time and continues to accumulate upward, 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, so as to further reduce the amount of film feeding, until the film on the top of the blanking plate 102 is completely blocked and intercepted, and the feeding into the shell 101 is stopped.

[0037] A stabilizing frame is fixed on the top of the housing 101, and a 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.

[0038] When the film accumulated inside the shell 101 is broken, the tooth plate 201f will release the restriction. At this time, the third spring applies a thrust to the second connecting block, and the second connecting block drives the tooth plate 201f to move, so that the tooth plate 201f can be reset, and the tooth plate 201f drives the gear 201e to rotate in the opposite direction, thereby resetting the block 201b upward.

[0039] The pressing assembly 300 is arranged in the shell 101, and includes a pressing plate 301a, a fixing sleeve 301b, a fixing column 301c and a first spring 301d. The pressing plate 301a is located in the shell 101, the fixing sleeve 301b is fixed to the top of the pressing plate 301a, the fixing column 301c is inserted into the fixing sleeve 301b, and the two ends of the first spring 301d are respectively fixed to the pressing plate 301a and the fixing column 301c.

[0040] When the fixed column 301c moves downward, the first spring 301d drives the pressure plate 301a to move downward, and the pressure plate 301a presses the film above the crushing roller downward, so that the film can quickly enter the crushing roller, thereby improving the overall crushing efficiency.

[0041] When the crushing roller fails to crush the film in time, it will cause excessive accumulation of film. At this time, when the pressure plate 301a contacts the film, it cannot press the film downward, and the pressure 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 in the fixed sleeve 301b.

[0042] Example 2 Reference Figure 1-Figure 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the housing 101 is rotatably connected to a rotating wheel 202a, a pull rope 202b is wound around the outer side of the rotating wheel 202a, and two ends of the pull rope 202b are respectively fixed to the rotating wheel 202a and the tooth plate 201f.

[0044] When the rotating wheel 202a rotates, the pull rope 202b is reeled in, so that the tooth plate 201f can be driven to move by the pull rope 202b.

[0045] Specifically, a positioning column 202c is fixed on the top of the pressure plate 301a, a second fixed shaft 202d is fixed on one side of the positioning column 202c, a second spiral groove 301c-1 is opened in the fixed column 301c, the second fixed shaft 202d slides in the second spiral groove 301c-1, a slider 202e is fixed in the rotating wheel 202a, a sliding groove 301c-2 is opened on the fixed column 301c, and the slider 202e slides in the sliding groove 301c-2.

[0046] The rotating wheel 202a is connected to the fixed column 301c by the cooperation of the slider 202e and the slide groove 301c-2, so that the fixed column 301c can drive the rotating wheel 202a to rotate and can also move up and down in the rotating wheel 202a.

[0047] When the fixing column 301c moves downward in the fixing sleeve 301b, the second fixing shaft 202d will slide in the second spiral groove 301c-1, and the fixing column 301c will be driven to rotate by the cooperation of the two, so that the fixing column 301c can drive the rotating wheel 202a to rotate.

[0048] Specifically, a support frame 203a is fixed to one side of the fixing sleeve 301b, a clamping block 203b is arranged in the supporting frame 203a, a second spring 203c is fixed to one side of the clamping block 203b, and a clamping slot 301c-3 is opened on the fixing column 301c, and the number of the clamping slots 301c-3 is three.

[0049] The slot 301c-3 is annular, and one side of the block 203b is inclined and extends to the inside of the fixed sleeve 301b. When the fixed column 301c moves downward in the fixed sleeve 301b, it will contact the inclined surface of the block 203b and push the block 203b to move into the support frame 203a. When the lowest slot 301c-3 coincides with the block 203b, the second spring 203c applies a thrust to the block 203b and makes the block 203b engage with the slot 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, and the rotating wheel 202a can keep the pull rope 202b in the state of being wound, thereby preventing the tooth plate 201f from resetting.

[0050] The three slots 301c - 3 correspond to the three tooth plates 201f . As the downward movement of the fixing column 301c in the fixing sleeve 301b increases, the block 203b will be engaged with the two upper slots 301c - 3 in sequence.

[0051] Specifically, a force block 204a is fixed on the top of the clamping block 203b, an extrusion block 204b is arranged on one side of the force block 204a, a connecting column 204c is fixed on 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 block 204a.

[0052] When the connecting column 204c moves, it will drive the extrusion block 204b to squeeze the force block 204a, and drive the clamping block 203b to move through the force block 204a, so that the clamping block 203b can be separated from the clamping slot 301c-3, and the restriction on the fixed column 301c can be released, so that the fixed column 301c can be reset.

[0053] A plurality of stabilizing rods are fixed on the top of the pressure plate 301a, and the connecting column 204c is movably connected to the stabilizing rods to support and position the connecting column 204c.

[0054] Specifically, a support block 204d is fixed to the inner wall of the housing 101, one side of the support block 204d is rotatably connected to the force-bearing plate 204e, and one side of the support block 204d is fixed to a top block 204f, which contacts the force-bearing plate 204e and supports the force-bearing plate 204e.

[0055] 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 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 be squeezed by the force-bearing plate 204e to drive the squeezing block 204b to move.

[0056] When the connecting column 204c moves upward and contacts the force-bearing plate 204e, it pushes the force-bearing plate 204e to rotate upward, while the connecting column 204c does not move at this time.

[0057] Example 3 Reference Figure 1 to Figure 10 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0058] Specifically, a material blocking plate 302 is fixed to one side of the pressing plate 301 a , and a guide plate 303 is fixed inside the housing 101 , and the guide plate 303 is inclined.

[0059] When the pressure plate 301a presses the film downward, the film entering the shell 101 can be blocked by the baffle plate 302 to prevent it from falling to the top of the pressure plate 301a, and the guide plate 303 can guide the falling film so that it can fall between the two crushing rollers.

[0060] Specifically, a support frame 304 is fixed on the top of the housing 101 , a cylinder 305 is disposed in the support frame 304 , and an output end of the cylinder 305 is rotatably connected to the fixed column 301 c via a bearing.

[0061] 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.

[0062] Specifically, a support plate 202f is fixed to one side of the housing 101, a guide wheel 202g is provided on the top of the support plate 202f, and the pull rope 202b is wound around the outside of the guide wheel 202g.

[0063] The guide wheel 202g is used to guide and position the pull rope 202b.

[0064] Specifically, the main assembly 100 further includes a crushing roller 103 and a discharging mechanism 104 . The crushing roller 103 is located in the housing 101 , and the discharging mechanism 104 is disposed on one side of the housing 101 .

[0065] 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 described in detail in this solution.

[0066] In summary, the rotary crusher for recycling and regenerating waste film invented by us has the following effects: 1. It can press the film, force the film to be fed, and improve the crushing efficiency; 2. When the film inside the crusher accumulates, the amount of material fed can be automatically intercepted; 3. It can adaptively intercept the amount of film according to the amount of film accumulated inside the crusher; 4. After interception, the amount of film feeding can be slowly increased according to the amount of material discharged from the accumulated film.

[0067] When in use, the feeding conveyor belt is set on one side of the blanking plate 102, and the film transported by the conveyor belt will fall to the top of the blanking plate 102, and the film will be transported to the inside of the shell 101 through the blanking plate 102, so as to complete the loading, and then the cylinder 305 is started to drive the fixed column 301c to move downward. When the fixed column 301c moves downward, the pressure plate 301a is driven downward by the first spring 301d, and the film above the crushing roller is pressed downward by the pressure plate 301a, so that the film can quickly enter the inside of the crushing roller, thereby improving the overall crushing efficiency.

[0068] When the crushing roller fails to crush the film in time, it will cause excessive accumulation of film. At this time, when the pressure plate 301a contacts the film, it cannot press the film downward, and the pressure 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 in the fixed sleeve 301b. At this time, the second fixed shaft 202d slides in the second spiral groove 301c-1, and the cooperation of the two drives the fixed column 301c to rotate, so that the rotating wheel 202a can be driven to rotate through the fixed column 301c, and when the rotating wheel 202a rotates, the pull rope 202b will be reeled in, so that the tooth plate 201f can be driven to move through the pull rope 202b.

[0069] At this time, the toothed plate 201f on the right will move to the right and drive the gear 201e to rotate, and the gear 201e will drive 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 cooperation of the two will drive the block 201b to move downward, so that the block 201b on the right moves downward to the conveying channel on the right, and blocks the film inside the channel, so that it cannot enter the shell 101, thereby reducing the amount of film loading, allowing the crushing roller to fully crush the accumulated film, thereby avoiding uneven size of the crushed material.

[0070] At this time, the middle tooth plate 201f is meshed with the gear 201e, and the left tooth plate 201f is close to the gear 201e. After reducing the feeding, if the accumulated film inside the shell 101 still cannot be broken in time and continues to accumulate upward, 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, so as to further reduce the amount of film feeding, until the film on the top of the blanking plate 102 is completely blocked and intercepted, and the feeding into the shell 101 is stopped.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
