Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of rubber and plastic processing equipment technology, and more specifically, to a cutting device for rubber and plastic products. Background Technology
[0002] Rubber and plastics are a collective term for the rubber and plastics industries. They are both byproducts of petroleum, but their physical properties and uses differ during the manufacturing process. Rubber is most widely used in tires, while plastics are becoming increasingly widespread due to technological and market demands and are now indispensable in daily life.
[0003] Currently, operators frequently need to use cutting devices when processing rubber and plastic products. However, while existing cutting devices have basic cutting functions, they cannot perform cutting operations at different angles because the cutting blade is fixed during the cutting process. As a result, when operators need to cut rubber and plastic products at different angles, the device cannot meet their operational needs, thus reducing its application range. Therefore, improvements are needed. Utility Model Content
[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a cutting device for rubber and plastic products, which solves the technical problem in the related art that it is impossible to cut at different angles.

[0007] As a preferred embodiment of this utility model, table legs are fixedly connected to the four corners of the bottom of the workbench, and the number of table legs is four, with the four table legs having the same size.
[0008] As a preferred technical solution of this utility model, a material block is fixedly connected to both the left and right sides in front of the top of the workbench. A second pneumatic cylinder is fixedly installed on the top of the material block. The bottom end of the second pneumatic cylinder passes through the material block and extends into the interior of the material block and is fixedly connected to a clamping block.
[0009] As a preferred embodiment of this utility model, a No. 3 pneumatic cylinder is fixedly installed at the rear of the left side of the workbench, and a toothed plate is fixedly connected to the right end of the No. 3 pneumatic cylinder.
[0010] As a preferred embodiment of this utility model, a movable shaft is movably connected inside the back of the connecting frame, and the other end of the movable shaft passes through the workbench and extends to the outside of the back of the workbench.
[0011] As a preferred embodiment of this utility model, a gear is fixedly sleeved on the outer surface of the movable shaft, and the outer surface of the gear meshes with the outer surface of the gear plate.

[0014] As a preferred embodiment of this utility model, the bottom end of the connecting frame is fixedly connected to a limiting block located inside the workbench, and the outer surface of the limiting block is movably connected to the interior of the workbench.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. In this disclosure, by setting up a servo motor, a rotating shaft, a long rod, a moving rod, and a connecting block, when the operator starts the servo motor, the rotating shaft and the long rod will rotate, which will cause the moving rod to drive the connecting block to move as a whole, and then the first pneumatic cylinder will drive the cutting blade to rotate. This operation allows the operator to perform cutting operations on the rubber and plastic products between the two material blocks at different angles, thereby increasing the application range of the cutting device and bringing convenience to the operator in actual use.
[0017] 2. In this disclosure, by setting up a No. 3 pneumatic cylinder, a toothed plate, a gear, a movable rod, and a round shaft, the operator operates the No. 3 pneumatic cylinder, which causes the toothed plate to reciprocate left and right, thereby causing the outer surface of the toothed plate to mesh with the outer surface of the gear. This causes the gear to drive the movable shaft and the movable rod to rotate. At this time, the inner surface of the movable rod will squeeze and push the outer surface of the round shaft, thereby causing the round shaft to drive the entire connecting frame to reciprocate left and right, thus enabling the cutting blade to perform a cutting operation on the rubber and plastic products in one go.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5As shown, it illustrates a cutting device for rubber and plastic products according to an embodiment of the present disclosure, including a worktable 1, a connecting frame 2 movably connected to the rear of the top of the worktable 1, a servo motor 3 fixedly installed at the rear of the top right side of the connecting frame 2, a rotating shaft 4 fixedly sleeved at the other end of the output shaft of the servo motor 3, a long rod 5 fixedly sleeved on the outer surface of the rotating shaft 4, a moving rod 6 hinged to the other end of the long rod 5, a connecting block 7 hinged to the other end of the moving rod 6, a first pneumatic cylinder 8 fixedly sleeved inside the connecting block 7, the bottom end of the first pneumatic cylinder 8 passing through the connecting frame 2 and extending to the outside of the top of the inner surface of the connecting frame 2 and fixedly connected to a cutting blade 9, and the outer surface of the first pneumatic cylinder 8 movably connected to the inside of the connecting frame 2.
[0032] When the operator starts the servo motor 3, the rotating shaft 4 and the long rod 5 will rotate, which will cause the moving rod 6 to drive the connecting block 7 to move, which in turn will cause the first pneumatic cylinder 8 to drive the cutting blade 9 to rotate, so that the operator can perform cutting operations on the rubber products at different angles.
[0033] In some examples, the bottom end of the outer surface of the first pneumatic cylinder 8 is fixedly sleeved with a ring 10 located inside the top of the connecting frame 2, and the outer surface of the ring 10 is movably connected to the interior of the connecting frame 2.
[0034] Due to the design of the ring 10, the movement of the first pneumatic cylinder 8 can be effectively limited.
[0035] In some examples, table legs 11 are fixedly connected to the four corners of the bottom of the workbench 1. There are four table legs 11, and the four table legs 11 are the same size.
[0036] The design of the four table legs 11 provides excellent support for the entire workbench 1.
[0037] In some examples, material blocks 12 are fixedly connected to the left and right sides in front of the top of the workbench 1. A second pneumatic cylinder 13 is fixedly installed on the top of the material block 12. The bottom end of the second pneumatic cylinder 13 passes through the material block 12 and extends into the interior of the material block 12 and is fixedly connected to a clamping block 14.
[0038] When the operator operates the second pneumatic cylinder 13, the two clamping blocks 14 will move downwards.
[0039] In some examples, a No. 3 pneumatic cylinder 15 is fixedly installed at the rear left side of the workbench 1, and a toothed plate 16 is fixedly connected to the right end of the No. 3 pneumatic cylinder 15.
[0040] When the operator operates the No. 3 pneumatic cylinder 15, the toothed plate 16 will reciprocate left and right.
[0041] In some examples, the inner side of the back of the connecting frame 2 is movably connected to a movable shaft 17, the other end of which passes through the worktable 1 and extends to the outside of the back of the worktable 1.
[0042] Since both the outer surface of the movable shaft 17 and the interior of the worktable 1 are smooth, the movement of the movable shaft 17 inside the worktable 1 is smoother.
[0043] In some examples, a gear 18 is fixedly sleeved on the outer surface of the movable shaft 17, and the outer surface of the gear 18 meshes with the outer surface of the gear plate 16.
[0044] When the toothed plate 16 reciprocates left and right, the outer surface of the toothed plate 16 will mesh with the outer surface of the gear 18, thereby causing the gear 18 to drive the movable shaft 17 to rotate.
[0045] In some examples, the outer surface of the movable shaft 17 is fixedly fitted with a movable rod 19 located directly in front of the gear 18, and the interior of the movable rod 19 is hollow.
[0046] When the movable shaft 17 rotates, it will cause the movable rod 19 to rotate as well.
[0047] In some examples, a circular shaft 20 is movably connected inside the movable rod 19, with the other end of the circular shaft 20 passing through the movable rod 19 and extending to the back of the connecting frame 2 and being fixedly connected to the back of the connecting frame 2.
[0048] When the movable rod 19 rotates, the internal pressure of the movable rod 19 will push the outer surface of the round shaft 20, thereby causing the round shaft 20 to drive the connecting frame 2 to move back and forth.
[0049] In some examples, the bottom end of the connecting frame 2 is fixedly connected to a limiting block 21 located inside the worktable 1, and the outer surface of the limiting block 21 is movably connected to the interior of the worktable 1.
[0050] Due to the design of the limit block 21, it can play a good guiding role for the entire connecting frame 2.
[0051] Working principle and usage process of this utility model:
[0052] First, the operator places the rubber and plastic product to be cut into the two material blocks 12 and operates the two second-stage pneumatic cylinders 13, which causes the two clamping blocks 14 to move downwards, thus clamping and fixing the rubber and plastic product. Then, the operator operates the first-stage pneumatic cylinder 8 and the third-stage pneumatic cylinder 15. The operation of the first-stage pneumatic cylinder 8 causes the cutting blade 9 to move downwards into the interior of the rubber and plastic product, while the operation of the third-stage pneumatic cylinder 15 causes the toothed plate 16 to reciprocate left and right. At this time, the outer surface of the toothed plate 16 will mesh with the outer surface of the gear 18, which will cause the gear 18 to drive the movable shaft 17 and the movable rod 19 to rotate. This causes the inner surface of the movable rod 19 to squeeze and push the outer surface of the round shaft 20, which in turn causes the round shaft 20 to drive the connecting frame 2 to reciprocate left and right, thus enabling the cutting blade 9 to perform a one-time cutting operation on the rubber and plastic product.
[0053] Finally, when the operator needs to cut the rubber and plastic products at different angles, the operator starts the servo motor 3, which will cause the rotating shaft 4 and the long rod 5 to rotate. This will cause the moving rod 6 to drive the connecting block 7 to move as a whole, which will cause the first pneumatic cylinder 8 to drive the cutting blade 9 to rotate. At this time, the operator can cut the rubber and plastic products between the two material blocks 12 at different angles.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
