Description

Technical Field

[0001] This application relates to the technical field of rubber product processing, and in particular to a trimming device for rubber product processing. Background Technology

[0002] Rubber products are a general term for finished products made primarily from rubber through a series of processing steps. Common characteristics of rubber products include exceptional high elasticity and excellent properties such as wear resistance, shock absorption, insulation, and sealing. The rubber industry produces a wide variety of rubber products in numerous specifications. Due to the unique properties of rubber, after processing, rubber products often have excess material at the edges, requiring appropriate trimming equipment for later use.

[0003] A utility model patent with Chinese patent authorization announcement number CN219114565U discloses a trimming device for processing rubber products. The device includes a processing table, a clamping mechanism slidably connected to the top of the processing table, and a trimming mechanism fixedly connected to the top of the processing table. An opening is formed at the top of the processing table, and a rectangular groove is formed on the right side of the processing table. A collection box is placed at the bottom inner side of the rectangular groove, with the position of the collection box symmetrical to the position of the opening. Using this structure, when scraps from rubber products are scraped off by a blade, these scraps fall into the opening and then into the collection box, where they are collected. When cleaning these scraps is needed, the handle is grasped, and the collection box is pulled out of the rectangular groove. The anti-slip layer reduces friction between the hand and the handle, preventing the hand from slipping and facilitating the pulling out of the collection box, thus achieving the beneficial effect of conveniently cleaning scraps.

[0004] The proposed solution has the following problems: The device uses a sliding L-shaped plate and a first blade to trim square rubber products. A round rubber product requiring trimming is placed where the turntable intersects with the second blade. The user can use the sliding principle of the third groove to slide the slider and use the second blade for repair. However, this solution has several issues. For example, during trimming, operators may accidentally come into contact with the sharp edge of the blade, resulting in cuts, scratches, or other injuries. The directly exposed blade is also susceptible to external impacts and scratches. For instance, during equipment handling, routine maintenance, or the installation and disassembly of other components, accidental contact with the blade can cause chipping, breakage, or other damage to the blade edge, affecting trimming accuracy and blade lifespan. Furthermore, since the first and second blades are fixedly connected, when the blades become dull and worn after a period of use, replacement often takes a long time, reducing equipment maintenance efficiency.

[0005] Therefore, in order to solve the above problems, this application provides a trimming device for processing rubber products. Utility Model Content

[0006] In order to address the problem that operators may suffer cuts, scratches, or other bodily injuries due to operational errors, negligence, or accidental contact with the sharp edge of the blade during the trimming process, this application provides a trimming device for processing rubber products.

[0007] This application provides a trimming device for processing rubber products, comprising a fixed block and a slider. A first blade is provided on one side of the fixed block, and a second blade is provided on one side of the slider. A protective mechanism is provided on one side of both the fixed block and the slider. The protective mechanism includes:

[0008] The top of the fixed block is hinged to a protective cover one, and a sliding groove is opened through the top of the protective cover one. A movable block is slidably installed in the sliding groove. A support rod is fixedly connected to the top of the movable block. The top of the support rod is in contact with the bottom of the protective cover one. A second protective cover is fixedly connected to the side of the slider away from the second blade.

[0009] Both the fixing block and the slider are equipped with a snap-fit ​​device on the side near the first and second blades.

[0010] Preferably, the side of the second protective cover near the second blade is set to be arc-shaped, and the first protective cover and the second protective cover are L-shaped.

[0011] Preferably, both the first protective cover and the second protective cover are made of transparent acrylic material.

[0012] Preferably, reflective strip one is affixed to the inner side of the first protective cover, and reflective strip two is affixed to the inner side of the second protective cover.

[0013] Preferably, a support base is provided between the fixed block and the slider, the fixed block is fixedly connected to one side of the support base, and the slider is slidably connected to the support base.

[0014] Preferably, both the first blade and the second blade have handles on the side away from the trimming edge.

[0015] Preferably, a throttle is fixedly connected to the side of the protective cover that is hinged to the fixing block.

[0016] Preferably, the snap-fit ​​device includes:

[0017] The fixed block and the slider are both provided with a through mounting groove on one side. A mounting seat is fixedly connected in each of the two mounting grooves. An arc-shaped plate is hinged in each of the two mounting seats. A connecting block is fixedly connected to one side of the first blade and the second blade. A limiting plate is fixedly connected to one side of each of the two connecting blocks. The limiting plate is adapted to the two arc-shaped plates. A connecting plate is fixedly connected to both sides of each of the two arc-shaped plates. An elastic element is fixedly connected to one side of each of the two connecting plates and the mounting seat.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by setting up a protective cover one and a protective cover two to protect the first and second blades, it can effectively prevent operators from accidentally touching the sharp blades, avoid accidents such as cuts and scratches, prevent the blades from being accidentally bumped or scratched, and buffer external impacts to a certain extent, protecting the integrity of the blade edge. At the same time, the protective cover two can limit the rubber debris generated by the trimming of the second blade to a certain area, making it easy to clean up, reducing the accumulation of debris on other parts of the equipment, and reducing the difficulty and workload of cleaning the equipment.

[0020] 2. In this utility model, by setting a handle, the connecting block on the first blade or the second blade is separated from the limiting plate. When the two limiting plates are obstructed from moving outward, the two arc-shaped plates can be moved outward through the elastic element, realizing the quick disassembly and assembly of the blade, greatly shortening the replacement time. It is especially suitable for scenarios with frequent blade changes in mass production, reducing downtime losses caused by blade changes. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, as Figure 1-4 As shown, this utility model provides a trimming device for processing rubber products, including a fixed block 2, a slider 7, a protective mechanism, and a snap-fit ​​device. A first blade 3 is provided on one side of the fixed block 2, and a second blade 9 is provided on one side of the slider 7. The protective mechanism includes: a protective cover 4 hinged to the top of the fixed block 2; a groove is provided through the top of the protective cover 4; a movable block 11 is slidably installed in the groove; a support rod 6 is fixedly connected to the top of the movable block 11; the top of the support rod 6 contacts the bottom of the protective cover 4; and a second protective cover 8 is fixedly connected to the side of the slider 7 away from the second blade 9. The protective cover 2 8 is curved on the side near the second blade 9. The protective cover 1 4 and the protective cover 2 8 are L-shaped. Both the protective cover 1 4 and the protective cover 2 8 are made of transparent acrylic material. The inner side of the protective cover 1 4 is attached with reflective strip 1 5, and the inner side of the protective cover 2 8 is attached with reflective strip 2 20. A support base 1 is provided between the fixing block 2 and the slider 7. The fixing block 2 is fixedly connected to one side of the support base 1, and the slider 7 is slidably connected to the support base 1. The side of the first blade 3 1 and the second blade 9 away from the trimming edge is provided with a handle 10. The side of the protective cover 1 4 that is hinged to the fixing block 2 is fixedly connected with a throttle handle 12.

[0029] In this embodiment, when using the first blade 3 to trim the rubber product, the handle 12 can be rotated. Rotating the handle 12 causes the protective cover 4 to rotate upward. After the protective cover 4 rotates to the top, the sliding block 11 and the support rod 6 can be slid to move the support rod 6 to the bottom of the protective cover 4 to support it. Then, the first blade 3 is used to trim the rubber product. After trimming, the support rod 6 and the slider 7 are moved to one side and rotated to make the protective cover rotate downward to protect the first blade 3. When using the second blade 9 to trim the rubber product, the slider 7 can be slid to trim the round rubber product. At the same time, the second protective cover 8 is L-shaped so that the worker's hand will not accidentally touch the second blade 9, avoiding cuts, scratches and other bodily injuries.

[0030] Example 2, as Figure 1-4As shown, the snap-fit ​​device includes: a mounting groove 16 is provided through one side of both the fixing block 2 and the slider 7; a mounting base 13 is fixedly connected in both mounting grooves 16; an arc plate 15 is hinged in both mounting bases 13; a connecting block 17 is fixedly connected to one side of the first blade 3 and the second blade 9; a limiting plate 14 is fixedly connected to one side of both connecting blocks 17; the limiting plate 14 is adapted to the two arc plates 15; a connecting plate 19 is fixedly connected to both sides of both arc plates 15; and an elastic element 18 is fixedly connected to one side of both connecting plates 19 and the mounting base 13.

[0031] In this embodiment, when it is necessary to disassemble the first blade 3 and the second blade 9, the handle 10 can be pulled outward to disengage the connecting block 17 and the limiting plate 14 from the two limiting plates 14. When the outward movement of the two limiting plates 14 is obstructed, the two arc plates 15 can be moved outward through the elastic member 18, thereby disassembling the first blade 3 and the second blade 9. When it is necessary to install the first blade 3 and the second blade 9, the handle 10 can be used to place the connecting block 17 and the limiting plate 14 into the mounting groove 16, and then the limiting plate 14 can be inserted between the two arc plates 15. The widest part of the arc plate 15 allows the two arc plates 15 to move outward through the elastic member 18, thereby allowing the limiting plate 14 to enter the interior of the two limiting plates 14, completing the installation of the first blade 3 and the second blade 9.

[0032] Working principle: When in use, the handle 12 can be turned, which will cause the protective cover 4 to rotate upward. After the protective cover 4 rotates to the top, the sliding block 11 and the support rod 6 can be slid to move the support rod 6 to the bottom of the protective cover 4 to support it. Then, the first blade 3 is used to trim the rubber product. After trimming, the support rod 6 and the slider 7 are moved to one side and rotated to make the protective cover rotate downward to protect the first blade 3. When using the second blade 9 to trim the rubber product, the slider 7 can be slid to trim the round rubber product. At the same time, the protective cover 8 is L-shaped, so that the operator's hand will not accidentally touch the second blade 9, avoiding cuts, scratches and other bodily injuries.

[0033] When it is necessary to disassemble the first blade 3 and the second blade 9, the handle 10 can be pulled outward to disengage the connecting block 17 and the limiting plate 14 from the two limiting plates 14. When the outward movement of the two limiting plates 14 is obstructed, the two arc plates 15 can be moved outward through the elastic member 18, thereby disassembling the first blade 3 and the second blade 9. When it is necessary to install the first blade 3 and the second blade 9, the handle 10 can be used to place the connecting block 17 and the limiting plate 14 into the mounting groove 16, and then the limiting plate 14 can be inserted between the two arc plates 15. The widest part of the arc plate 15 allows the two arc plates 15 to move outward through the elastic member 18, thereby allowing the limiting plate 14 to enter the interior of the two limiting plates 14, completing the installation of the first blade 3 and the second blade 9.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
