Description

Technical Field

[0001] This utility model relates to the field of fabric processing equipment technology, specifically to a rotary cutter shredder. Background Technology

[0002] This meat grinder is a device used in the food industry for dicing frozen meat, and recycling and chopping dumpling wrappers, wonton wrappers, and other dough waste. Referring to the applicant's previously filed and published utility model patent: Roller Cutter, patent application number 2023224167222, this technology includes: a hopper; a cutter holder disposed at the bottom of the hopper; and multiple roller cutter assemblies disposed on both sides of the cutter holder. Each roller cutter assembly includes a cutter shaft, multiple circular blades, and multiple toothed blades. The circular blades and toothed blades are all fixedly sleeved on the cutter shaft. This meat grinder has the advantages of low labor intensity, high production capacity, and high safety.

[0003] However, in the above structure, when a large amount of dough scraps are put into the hopper, the dough scraps will accumulate and cannot be fed smoothly. At this time, it is necessary to manually stir and turn the dough over so that the dough can fall smoothly into the roller. This situation poses certain safety hazards in actual operation, so the feeding method needs to be improved. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a rotary cutter crusher.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A rotary cutter crusher includes a frame, a feeding hopper, a crushing trough, a rotary cutter mechanism, and an output motor.

The material control mechanism includes a rotary cutter rotatably installed in the feeding hopper, a material control plate movably installed on the left and right sides of the rotary cutter, and a drive motor installed on the outside of the feeding hopper. The drive motor drives the rotary cutter to rotate for initial crushing, and the output motor drives the rotary cutter mechanism to rotate for secondary crushing. The material control plate controls the falling speed of the tail material.

[0007] In this invention, the outward-facing end of the crushing trough is raised by 12° to 18° to tilt the crushing trough.

[0008] In this utility model, the control plate on the left is slidably mounted on the feeding hopper, and the control plate on the right is rotatably mounted on the feeding hopper. An adjustment seat is provided on the outside of the feeding hopper. One end of the control plate on the left is adjustablely mounted on the adjustment seat, and the other end extends into the inside of the feeding hopper. A rotating seat is provided on the other side of the feeding hopper. One end of the control plate on the right extends outward and is connected to a rotating handle. The rotating handle is adjustablely mounted on the rotating seat.

[0009] In this utility model, the rotary blade mechanism includes a rotating shaft installed at an inclination along the direction of the crushing trough, and a plurality of cutters and partitions fitted on the rotating shaft. The two ends of the rotating shaft are rotatably installed at the two ends of the crushing trough, and the plurality of cutters and partitions are alternately fitted on the middle of the rotating shaft in sequence.

[0010] Furthermore, the cross-section of the central part of the rotating shaft is a polygonal structure, and the interval angle between two adjacent cutting blades is 90°.

[0011] Furthermore, the end of the rotating shaft near the output motor extends outward and passes through the crushing trough. The extended end of the rotating shaft is also provided with a driven wheel, which is connected to the output motor via a belt.

[0012] Furthermore, the rotary blade mechanism is provided in two sets and rotates in the same direction. The two sets of rotary blade mechanisms are arranged in parallel, and the cutting blade parts of the two sets of rotary blade mechanisms overlap but do not interfere with each other.

[0013] In this utility model, the bottom of the shredder is provided with two side covers that open outwards respectively, and the top of the shredder is provided with a top cover that closes the trough opening. The top of the side covers is hinged to the shredder, and the top cover is slidably fitted at the trough opening.

[0014] Furthermore, position sensors are installed on the crushing trough near the side cover and the top cover. The position sensors monitor whether the side cover and the top cover are fully closed. When it is detected that either the side cover or the top cover is not fully closed, the power is disconnected to stop the output motor from working.

[0015] This utility model has the following advantages and beneficial effects:

[0016] A material control mechanism is installed in the feeding hopper so that the dough scraps are initially crushed by the roller cutter after being put into the feeding hopper. The material control plates installed on both sides of the roller cutter control the falling speed of the dough scraps and agitate the dough scraps to prevent them from piling up, eliminating the need for manual agitation and avoiding safety hazards.

[0025] like Figures 1 to 4As shown, this embodiment discloses a rotary cutter crusher, including a frame 1, a feeding hopper 2, a crushing trough 3, a rotary cutter mechanism 4, and an output motor 5. The crushing trough 3 is installed above the frame 1, and the outward-facing end of the crushing trough 3 is raised upward by 12° to 18° to tilt the crushing trough 3, with the tilt angle preferably being 15°. The rotary cutter mechanism 4 is installed inside the crushing trough 3. The feeding hopper 2 is installed at the upper tilted position above the crushing trough 3, and the lower tilted end of the crushing trough 3 is provided with a discharge port 30. The output motor 5 is installed below the frame 1 and connected to the rotary cutter mechanism 4. A material control mechanism 6 is also provided at the connection between the hopper 2 and the crushing trough 3. The material control mechanism 6 includes a roller cutter 61 rotatably installed in the feeding hopper 2, a material control plate 62 movably installed on the left and right sides of the roller cutter 61, and a drive motor 63 installed on the outside of the feeding hopper 2. The drive motor 63 drives the roller cutter 61 to rotate, thereby initially crushing the dough tail material in the feeding hopper 2 and sending it into the crushing trough 3. The output motor 5 drives the rotary cutter mechanism 4 to rotate and further crush the dough tail material, which then falls out from the discharge port 30. A gap is left between the material control plate 62 and the roller cutter 61 to control the falling speed of the dough tail material.

[0026] A material control mechanism 6 is set in the feeding hopper 2 so that the dough tail material is initially crushed by the roller cutter 61 after being put into the feeding hopper 2. The material control plate 62, which is movably installed on both sides of the roller cutter 61, controls the falling speed of the dough tail material and stirs the dough tail material to prevent it from piling up, eliminating the need for manual stirring and avoiding safety hazards.

[0027] In this embodiment, the left-side control plate 62 is slidably mounted on the feeding hopper 2 to adjust the gap between it and the roller cutter 61. The right-side control plate 62 is rotatably mounted on the feeding hopper 2 to adjust the angle between it and the roller cutter 61. Specifically, an adjustment seat 64 is provided on the outer side of the feeding hopper 2. One end of the left-side control plate 62 is adjustablely mounted on the adjustment seat 64, and the other end of the left-side control plate 62 extends into the inner side of the feeding hopper 2. By changing the fixed position of the left-side control plate 62 on the adjustment seat 64, the distance between it and the roller cutter 61 is changed, thereby changing the gap size. A rotating seat 65 is provided on the other side of the feeding hopper 2. One end of the right-side control plate 62 extends outward and is connected to a rotating handle 66. The rotating handle 66 is adjustablely mounted on the rotating seat 65. By changing the fixed position of the rotating handle 66 on the rotating seat 65, the angle of the control plate 62 is adjusted.

[0028] In this embodiment, the rotary blade mechanism 4 includes a rotating shaft 41 installed at an incline along the direction of the crushing trough 3, and a plurality of cutters 42 and spacers 43 mounted on the rotating shaft 41. Specifically, the two ends of the rotating shaft 41 are rotatably installed at the two ends of the crushing trough 3. The cross-section of the middle part of the rotating shaft 41 is a polygonal structure. The plurality of cutters 42 and spacers 43 are alternately mounted on the middle part of the rotating shaft 41 in sequence. The interval angle between two adjacent cutters 42 is 90°. When the rotating shaft 41 rotates, it drives the cutters 42 to rotate and crush the dough tail material.

[0029] Furthermore, the end of the rotating shaft 41 near the output motor 5 extends outward and passes through the crushing trough 3. The extended end of the rotating shaft 41 is also provided with a driven wheel 44, which is connected to the output motor 5 via a belt.

[0030] Furthermore, the rotary blade mechanism 4 is provided in two sets, which are arranged in parallel. The cutters 42 in the two sets of rotary blade mechanisms 4 partially overlap but do not interfere with each other. In addition, the two sets of rotary blade mechanisms 4 rotate in the same direction.

[0031] In this embodiment, in order to facilitate the cleaning of leftover fabric scraps, two side covers 31 that open outwards are provided at the bottom of the scrap trough 3, and a top cover 32 that closes the trough opening is provided at the top of the scrap trough 3. The top of the side covers 31 is hinged to the scrap trough 3, and the top cover 32 is slidably fitted at the trough opening of the scrap trough 3. The fabric can be cleaned after the side covers 31 and the top cover 32 are opened.

[0032] Furthermore, position sensors 33 are provided on the crushing trough 3 near the side cover 31 and the top cover 32. The position sensors 33 are used to monitor whether the side cover 31 and the top cover 32 are fully closed. When it is detected that either the side cover 31 or the top cover 32 is not fully closed, the power supply will be disconnected to stop the output motor (5) from working, so as to avoid safety hazards.

[0033] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
