Description

Technical Field

[0001] This invention belongs to the field of cutting equipment technology, and specifically relates to a cutting device for plastic or paper materials. Background Technology

[0002] In order to ensure the accuracy of the test, it is often necessary to cut plastic or paper materials into standard fragments of different lengths and widths. Most existing cutters are blades or scissors, which can cut and process materials, but this method is not only time-consuming and labor-intensive, but also makes it difficult to control the length and width of the fragments after cutting. Summary of the Invention

[0003] The purpose of this invention is to provide a cutting device for plastic or paper materials to solve the problems of time-consuming and labor-intensive cutting methods, and the difficulty in controlling the length and width of the cut debris.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A cutting device for plastic or paper materials includes a feeding and flattening mechanism, a transverse cutting mechanism, and a longitudinal cutting mechanism. The feeding and flattening mechanism includes two side plates, and two sets of extrusion groups are rotatably mounted between the two side plates. The extrusion groups are inclined and include multiple rotating rollers connected by transmission and an extrusion belt wound around the rotating rollers. The transverse cutting mechanism includes two cutting rollers, one upper and one lower, rotatably mounted on the side plates. Multiple cutting rings are mounted on each of the two cutting rollers. The longitudinal cutting mechanism includes a lower blade fixedly mounted on the side plates and an upper blade movably mounted between the two side plates. A mounting frame is mounted on the side plates above the upper blade. A hydraulic mechanism is mounted on the mounting frame. The hydraulic mechanism includes a hydraulic cylinder fixedly mounted on the mounting frame and a hydraulic rod fixedly connected to the upper blade.

[0006] Furthermore, the outer surface of the extrusion belt is uniformly provided with multiple protruding ridges in the transverse direction. This structural design increases the friction between the extrusion belt and the material through the protruding ridges, preventing the material from slipping during processing.

[0007] Further specifying, the outer wall of the cutting roller has multiple transversely formed slot groups, each slot group comprising multiple sequentially connected slots, with all slots in the same slot group having equal lengths. The inner wall of the cutting ring is integrally formed with a protrusion, the inner side of which has a hemispherical groove. Several threaded blind holes are formed within the slots, and ball-head plungers are screwed into these blind holes. The ball head portion of the ball-head plunger is engaged within the hemispherical groove. This structural design, with the cutting ring fitted onto the cutting roller, prevents the cutting ring from rotating around the cutting roller during use through the interaction of the slots and the protrusion, and prevents the cutting ring from sliding along the cutting roller during use through the interaction of the ball-head plunger and the hemispherical groove.

[0008] Furthermore, the lengths of the slots in adjacent slot groups are unequal. This structural design, through the unequal lengths of the slots in adjacent slot groups, ensures that the distance between adjacent cutting rings differs when the protrusions of the cutting rings are engaged in different slot groups. This allows for the use of different widths to cut the material being cut by the transverse cutting mechanism, thereby altering the width of the material fragments after cutting.

[0009] Furthermore, the right end of the cutting roller is provided with a placement post, the diameter of which is smaller than the diameter of the cutting roller. This structural design allows the cutting ring to be temporarily pulled onto the placement post when the cutting ring is pulled laterally to disengage the protrusion from the slot assembly, and then rotated. When the distance between two adjacent cutting rings is large, resulting in excess cutting rings, these excess cutting rings can also be placed on the placement post.

[0010] Furthermore, the width of the multiple protrusions increases sequentially from left to right, and the width of the multiple slots in the same slot group also increases sequentially from left to right. This structural design, with multiple slots in the same slot group whose width increases sequentially from left to right, prevents the right-side cutting ring from being engaged with the left side of the corresponding slot. This makes subsequent adjustment of the cutting ring much easier; simply align the protrusion of the cutting ring with the corresponding slot group and push the cutting ring to the left.

[0011] Furthermore, the width of the protrusion is greater than the width of the cutting ring, and a positioning groove is also provided on the protrusion. The protrusion on the left side of the cutting ring is engaged in the positioning groove on the right side of the cutting ring. This structural design achieves mutual positioning of adjacent cutting rings through the matching of the protrusion and the positioning groove. After the protrusion of the cutting ring is pushed out of the original slot group, the cutting rings are stacked together and cannot rotate. After aligning the protrusion of the cutting ring with the corresponding slot group, the cutting ring can be pushed to the left, making adjustment more convenient.

[0012] Furthermore, two guide plates are fixedly installed on the side plate between the lower blade and the transverse cutting mechanism, and the two guide plates are in an inverted V-shape. This structural design guides the material cut by the transverse cutting mechanism through the two inverted V-shaped guide plates, making it easier for the material to enter between the lower blade and the upper blade.

[0013] Furthermore, the side plate is equipped with a receiving box in front of the longitudinal cutting mechanism. This structural design allows the receiving box to collect the debris from the cut material, preventing the debris from becoming scattered.

[0014] Further specifying, the receiving box has multiple grooves, and a mounting rod is secured to the receiving box via these grooves. A proximity switch is mounted on the mounting rod, located directly in front of the transverse cutting mechanism. The proximity switch is signal-connected to the hydraulic mechanism. This structural design allows adjustment of the distance between the proximity switch and the longitudinal cutting mechanism by installing the mounting rod in different grooves. Since the proximity switch is signal-connected to the hydraulic mechanism, after the transverse cutting mechanism performs a transverse cut on the material, it continues to push forward until it touches the proximity switch. At this point, the hydraulic mechanism quickly actuates, causing the upper blade to move downwards to cut the material. Adjusting the position of the proximity switch adjusts the length of the material cut by the vertical cutting mechanism, thereby changing the length of the material fragments after cutting.

[0015] The invention employing the above technical solution has the following advantages:

[0016] 1. The material is squeezed and cut twice by the feeding flattening mechanism, the transverse cutting mechanism and the longitudinal cutting mechanism. It is simple to use and the length and width dimensions can be effectively controlled.

[0017] 2. By using slots of different lengths in two adjacent slot groups, the distance between two adjacent cutting rings is different when the protrusion of the cutting ring is engaged in different slot groups. This allows for cutting of the material by the transverse cutting mechanism with different widths, thereby changing the width of the material fragments after cutting.

[0018] 3. By installing the mounting rod in different grooves, the distance between the proximity switch and the longitudinal cutting mechanism can be adjusted. The proximity switch is connected to the hydraulic mechanism. After the transverse cutting mechanism cuts the material laterally, it continues to push the material forward until it touches the proximity switch. At this time, the hydraulic mechanism moves quickly, causing the upper blade to move downward to cut the material. By adjusting the position of the proximity switch, the length of the material cut by the vertical cutting mechanism can be adjusted, thereby changing the length of the material fragments after cutting.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0036] like Figures 1-9 As shown, a plastic or paper material cutting device of the present invention includes a feeding and flattening mechanism 1, a transverse cutting mechanism 2, and a longitudinal cutting mechanism 3. The feeding and flattening mechanism 1 includes two side plates 10, and two sets of extrusion groups 11 are rotatably mounted between the two side plates 10. The extrusion groups 11 are inclined and include multiple rotating rollers 12 connected by transmission and an extrusion belt 13 wound around the rotating rollers 12. The transverse cutting mechanism 2 includes two cutting rollers 21 rotatably mounted on the side plates 10, and multiple cutting rings 22 are mounted on each of the two cutting rollers 21. The longitudinal cutting mechanism 3 includes a lower blade 31 fixedly mounted on the side plates 10 and an upper blade 32 movably mounted between the two side plates 10. A mounting frame 33 is mounted on the side plates 10 above the upper blade 32. A hydraulic mechanism is mounted on the mounting frame 33. The hydraulic mechanism includes a hydraulic cylinder 331 fixedly mounted on the mounting frame 33 and a hydraulic rod 332 fixedly connected to the upper blade 32.

[0037] The outer side of the extrusion belt 13 is provided with multiple protruding ridges 130 evenly distributed laterally. The protruding ridges 130 increase the friction between the extrusion belt 13 and the material, preventing the material from slipping during processing.

[0038] The outer wall of the cutting roller 21 has multiple slot groups transversely formed, each slot group including multiple slots 201 connected in sequence. The slots 201 in the same slot group have equal lengths. The inner wall of the cutting ring 22 has integrally formed protrusions 221. The inner side of the protrusions 221 has hemispherical grooves 2211. Several threaded blind holes 202 are formed within the slots 201, and ball-head plungers are screwed into the threaded blind holes 202. The ball head of the ball-head plunger is engaged within the hemispherical groove 2211. The cutting ring 22 is sleeved on the cutting roller 21. The interaction between the slots 201 and the protrusions 221 prevents the cutting ring 22 from rotating around the cutting roller 21 during use. The interaction between the ball-head plunger and the hemispherical groove 2211 prevents the cutting ring 22 from sliding along the cutting roller 21 during use.

[0039] The lengths of the slots 201 in two adjacent slot groups are different. By using slots 201 with different lengths in two adjacent slot groups, the distance between two adjacent cutting rings 22 is different when the protrusions 221 of the cutting ring 22 are engaged in different slot groups. This allows the material being cut by the transverse cutting mechanism 2 to be cut with different widths, thereby changing the width of the material fragments after cutting.

[0040] The right end of the cutting roller 21 is provided with a placement post 20, the diameter of which is smaller than that of the cutting roller 21. When the cutting ring 22 is pulled laterally to disengage the protrusion 221 from the slot assembly, the cutting ring 22 can be temporarily pulled onto the placement post 20, and then the cutting ring 22 can be rotated. When the distance between two adjacent cutting rings 22 is large, resulting in an excess of cutting rings 22, the excess cutting rings 22 can also be placed on the placement post 20.

[0041] The width of the multiple protrusions 221 increases sequentially from left to right, and the width of the multiple slots 201 in the same slot group also increases sequentially from left to right. By using multiple slots 201 in the same slot group with progressively increasing widths from left to right, the cutting ring 22 on the right cannot be engaged with the left side of the corresponding slot 201. This makes subsequent adjustment of the cutting ring 22 much easier; simply align the protrusions 221 of the cutting ring 22 with the corresponding slot group and then push the cutting ring 22 to the left.

[0042] The width of the protrusion 221 is greater than the width of the cutting ring 22. The protrusion 221 also has a positioning groove 2212. The protrusion 221 on the left cutting ring 22 is engaged in the positioning groove 2212 on the right cutting ring 22. Through the matching of the protrusion 221 and the positioning groove 2212, the two adjacent cutting rings 22 are mutually positioned. After pushing the protrusion 221 of the cutting ring 22 out of its original slot group, the cutting rings 22 overlap and cannot rotate. Then, after aligning the protrusion 221 of the cutting ring 22 with the corresponding slot group, the cutting ring 22 can be pushed to the left, making adjustment more convenient.

[0043] Two guide plates 30 are fixedly installed on the side plate 10 between the lower blade 31 and the transverse cutting mechanism 2. The two guide plates 30 are in an inverted V-shape. The two inverted V-shaped guide plates 30 guide the material cut by the transverse cutting mechanism 2, so that the material can enter the space between the lower blade 31 and the upper blade 32 more easily.

[0044] The side plate 10 is also provided with a receiving box 4 in front of the longitudinal cutting mechanism 3. The receiving box 4 is used to receive the debris of the cut material to prevent the debris from becoming messy.

[0045] The receiving box 4 has multiple grooves 40, and the receiving box 4 is fitted with a mounting rod 41 through the grooves 40. A proximity switch 42 is mounted on the mounting rod 41. The proximity switch 42 is located directly in front of the transverse cutting mechanism 2 and is connected to the hydraulic mechanism. By installing the mounting rod 41 in different grooves 40, the distance between the proximity switch 42 and the longitudinal cutting mechanism 3 can be adjusted. Since the proximity switch 42 is connected to the hydraulic mechanism, after the transverse cutting mechanism 2 performs transverse cutting on the material, it continues to push the material forward until it touches the proximity switch 42. At this time, the hydraulic mechanism quickly moves, causing the upper blade 32 to move downward to cut the material. By adjusting the position of the proximity switch 42, the length of the material cut by the vertical cutting mechanism 3 can be adjusted, thereby changing the length of the material fragments after cutting.

[0046] In this embodiment, during use, after the feeding flattening mechanism 1 and the transverse cutting mechanism 2 are running, the material is placed from the right side of the feeding flattening mechanism 1 between the two extrusion groups 11. The feeding flattening mechanism 1 extrudes the material into a sheet shape and drives the extruded material to move to the left until the extruded material enters the transverse cutting mechanism 2 and is transversely cut by the cutting rings 22 on the two cutting rollers 21. Then it continues to move to the left until it is vertically cut by the vertical cutting mechanism 3.

[0047] The above provides a detailed description of a plastic or paper material cutting device provided by the present invention. The specific embodiments are described only to aid in understanding the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
