Description
Technical Field
[0001] This utility model relates to the field of cutting technology, and in particular to a soft rubber cutting device. Background Technology
[0002] In the general plastics industry, plastics such as PP and PE, which are lightweight and have relatively low surface hardness, are called soft plastics. Soft plastics are formed by injection molding. They feel soft to the touch at room temperature, have low surface tension, and low surface energy. Due to these characteristics, the most common cutting method for soft plastics on the market is die-cutting. This method involves cutting holes or severing the soft plastic, which requires changing its shape. Soft plastics usually undergo significant deformation during cutting, resulting in large kerfs. This method cannot achieve the effect of creating a closed cut without altering the original shape, as is the case with silicone. Utility Model Content
[0003] The main technical problem solved by this utility model is to provide a soft rubber cutting device that can cut slits in soft rubber without damaging the product or changing its original shape. When the cutter is removed, the cut will close automatically to form a sealed slit. When the cut needs to be opened, external force is used to open the cut to form a passage. When the cut does not need to be opened, the cut will close automatically when the external force is removed, thus achieving a sealing effect and avoiding all or some of the above defects.
[0004] To solve the above-mentioned technical problems, the present invention provides a soft rubber cutting device, which includes a frame, a cutting mechanism and a soft rubber fixing mechanism, wherein the cutting mechanism and the soft rubber fixing mechanism are both mounted on the frame.
[0005] The cutting mechanism includes a drive unit, a cutter, and a cutter mounting component. The drive unit is used to drive the cutter mounting component to move. The cutter mounting component is fixed to the output shaft of the drive unit. The cutter is fixed to the cutter mounting component, and the end of the cutter protrudes from the end of the cutter mounting component.
[0006] The soft rubber fixing mechanism includes a fixture and a support column. The fixture includes a receiving cavity with openings at both ends. The support column is located at one of the openings of the fixture. The soft rubber is placed on the support column and is contained within the receiving cavity. The side of the soft rubber abuts against the inner wall of the receiving cavity. The other end of the fixture opens towards the cutter, and the soft rubber is located on the travel path of the cutter.
[0007] The soft rubber cutting device further includes a guiding mechanism, which is used to limit the movement direction of the cutter.
[0008] The guiding mechanism includes a guide sleeve, a guide post, and a mounting plate;
[0009] The guide sleeve is fitted onto the guide post, and the guide sleeve can slide along the axial direction of the guide post;
[0010] The guide post is fixed to the frame and passes through the mounting plate;
[0011] The mounting plate is fixedly connected to the guide sleeve, and the output shaft of the drive unit passes through the center of the mounting plate and is fixedly connected to the mounting plate.
[0012] The drive unit has an output shaft fitted with a mounting ring, and the top of the mounting plate has a snap-fit component that holds the mounting ring. The cutter mounting component is located at the bottom of the mounting plate, so that the drive unit drives the mounting plate to move together.
[0013] The number of guide posts is four, and the four guide posts are respectively distributed in four directions of the mounting plate.
[0014] The frame also includes a base plate, which is horizontally fixed to the frame. The fixture and the guide column are both located on the base plate.
[0015] The base plate has a mounting groove on its top, the shape of which is the same as that of the fixture, and the fixture is accommodated in the mounting groove.

[0017] The number of mounting slots is multiple, the centers of the multiple mounting slots coincide, and the multiple mounting slots are distributed in a circle with the center of the mounting slot as the center.
[0018] The soft rubber cutting device further includes multiple limiting posts, which are fixed to the top of the base plate and distributed in different directions of the base plate. The height of the limiting posts is the same as the height of the fixture.
[0019] The thickness of the cutter tip is 0.1 mm, and the thickness of the cutter blade is 0.01 mm.
[0020] Compared with the prior art, the beneficial effects of the soft rubber cutting device of this utility model are as follows: a fixture is set to wrap the side of the soft rubber, and a cutter mounting part and a support column are set to abut against the upper and lower parts of the soft rubber respectively. At the same time, space is reserved for the deformation of the soft rubber when cutting, so as to minimize the deformation of the soft rubber during the cutting process. A slit is cut on the soft rubber without changing the original shape of the product. When it is necessary to open the slit, the slit is opened by external force to form a slit. When the external force is removed, the slit will close by itself to form a sealed slit, thus achieving a sealing effect. Attached Figure Description

[0030] Please see Figures 1 to 5 , Figure 1 This is a three-dimensional structural diagram of the soft rubber cutting device of this utility model. The soft rubber cutting device includes a frame 1, a cutting mechanism 2, and a soft rubber fixing mechanism 3, used to cut soft rubber 100. The soft rubber 100 can be made of silicone or other soft materials, and is characterized by its softness and easy deformation. The overall shape of the soft rubber 100 can be a cylinder, cuboid, cube, or sphere, or of course, it can be irregularly shaped. For ease of understanding, this application uses a cylinder as an example to illustrate the soft rubber 100. The soft rubber 100 includes two ends located in the axial direction and an arc-shaped side located between the two ends. The frame 1 is placed on a horizontal plane, a table, or a tabletop to support other components. The cutting mechanism 2 and the soft rubber fixing mechanism 3 are both mounted on the frame 1. The cutting mechanism 2 is used to cut the soft rubber 100, and includes a drive unit 21, a cutter 22, and a cutter mounting member 23. The drive unit 21 includes a retractable output shaft for driving the cutter mounting member 23. The cutter mounting member 23 is fixed to the output shaft of the drive unit 21, and the cutter 22 is fixed to the cutter mounting member 23. The end of the cutter 22 protrudes beyond the end of the cutter mounting member 23, and a first distance H is formed between the ends of the two. Please refer to [reference needed] for details. Figure 2 and Figure 3 Part A of the text. For ease of understanding, the driving component 21 in this application is vertically arranged and extends and retracts in the vertical direction. The cutter 22 also moves up and down to cut accordingly. The soft rubber 100 and the soft rubber fixing mechanism 3 are placed directly below the driving component 21.
[0031] Specifically, the drive component 21 is a cylinder, hydraulic cylinder, or electric cylinder. Preferably, the drive component 21 in this application is a cylinder.
[0032] The soft rubber fixing mechanism 3 is used to fix and limit the soft rubber 100 before cutting. Based on the soft and easily deformable characteristics of the soft rubber 100, the soft rubber fixing mechanism 3 also has the function of wrapping the soft rubber 100 to minimize the deformation of the soft rubber 100 during cutting. The soft rubber fixing mechanism 3 includes a fixture 31 and a support column 32. The fixture 31 includes a receiving cavity with openings at both ends. The shape of the receiving cavity matches the soft rubber 100 and can be circular, polygonal, or irregular. The support column 32 is located at one end opening of the fixture 31. Taking the first opening of the fixture 31 as an example, one end of the soft rubber 100 is placed on the end of the support column 32, and the soft rubber 100 is accommodated in the receiving cavity. Specifically, the side of the soft rubber 100 abuts against the inner wall of the receiving cavity. The other end of the fixture 31, also known as the second opening, faces the cutter 22. The other end of the soft rubber 100 faces the cutter 22, and the soft rubber 100 is located on the path of the cutter 22. In operation, the cutter 22 can enter the fixture 31 through the second opening and travel to the end of the soft rubber 100 to cut it. When the cut reaches a certain depth, the cutter mounting part 23 will abut against the end of the soft rubber 100 to prevent it from deforming indefinitely. The cutter mounting part 23 not only serves to install and fix the cutter 22, but also limits the deformation of the soft rubber 100 within a certain range.
[0033] Due to the soft and easily deformable nature of the soft rubber 100, if it is not fixed, wrapped, and limited during cutting, it will deform significantly, resulting in a large kerf and persistent holes or gaps. The soft rubber cutting device of this application uses a fixture 31 to wrap around the side of the soft rubber 100 and a support column 32 to abut against the lower part of the soft rubber 100. Therefore, during cutting, the lower and side parts of the soft rubber 100 cannot deform; they can only deform and expand upwards. Simultaneously, since the end of the cutter 22 protrudes beyond the end of the cutter mounting member 23, a first distance H is formed between their ends. When the cutter 22 begins cutting the soft rubber 100 and travels downwards for the first distance H, the cutter mounting member 23 abuts against the upper part of the soft rubber 100. The first distance H is the reserved deformation space for the soft rubber 100 during cutting. By setting the above-mentioned parameters to restrict the deformation of the soft rubber 100 in all directions, the deformation of the soft rubber 100 during the cutting process can be minimized. Therefore, it is possible to make a cut on the soft rubber 100 without changing the original shape of the product. When it is necessary to open the cut, the cut is opened by external force to form a slit. When the external force is removed, the cut will close by itself to form a sealed slit, achieving a sealing effect. Ordinary cutting methods cannot achieve the above-mentioned cut requirements.
[0034] The soft rubber cutting device in this application also includes a guide mechanism 4, which is used to limit the movement direction of the cutter 22 and also limit the travel distance of the cutter 22.
[0035] Specifically, in one embodiment, the guiding mechanism 4 includes a guide sleeve 41, a guide post 42, and a mounting plate 43. The guide sleeve 41 is annular, the guide post 42 is cylindrical, and the mounting plate 43 can be a solid plate, all made of ordinary steel or stainless steel. The guide sleeve 41 is fitted onto the guide post 42, which is vertically fixed. The guide sleeve 41 can slide along the axial direction of the guide post 42, that is, slide up and down vertically. One end of the guide post 42 is fixed to the frame 1, and the other end passes through the mounting plate 43. The mounting plate 43 is fixedly connected to the guide sleeve 41, specifically, the two are fixedly connected by bolts. The output shaft of the driving component 21 passes through the center of the mounting plate 43 and is fixedly connected to the mounting plate 43, thereby causing the driving component 21 to drive the mounting plate 43 to move up and down. When the mounting plate 43 slides, it drives the guide sleeve 41 to slide up and down along the guide post 42. Due to the above structural limitations, the cutting mechanism 2 can only move up and down, achieving precise cutting.
[0036] In this application, a mounting ring 44 is sleeved on the output shaft of the drive component 21, and a snap-fit component 45 is provided on the top of the mounting plate 43. The snap-fit component 45 clamps the mounting ring 44, thereby locking the drive component 21 to the top of the mounting plate 43. The cutter mounting component 23 is located at the bottom of the mounting plate 43 and abuts against the mounting plate 43. Since the cutter mounting component 23 is fixedly connected to the drive component 21, the drive component 21 and the bottom of the mounting plate 43 are also locked, thereby causing the drive component 21 to drive the mounting plate 43 to move together.
[0037] In this application, there are four guide posts 42, which are distributed in four directions of the mounting plate 43, so that the driving component 21 and the mounting plate 43 are stable and do not wobble when sliding up and down, thus ensuring the accuracy of cutting.
[0038] In this application, the frame 1 also includes a base plate 5, which is horizontally fixed on the frame 1. The fixture 31 and the guide column 42 are both located on the base plate 5. Specifically, the fixture 31 is horizontally placed on the base plate 5 and is set at a 90-degree angle to the cutter 22.
[0039] In this application, the top of the base plate 5 is provided with a mounting groove 51. The shape of the mounting groove 51 is the same as that of the fixture 31, but the size of the mounting groove 51 is slightly larger than the outer size of the fixture 31. The fixture 31 is accommodated in the mounting groove 51, thereby limiting the fixture 31 and preventing the fixture 31 from shaking during cutting and affecting the cutting accuracy.
[0040] In this application, the number of mounting slots 51 can be one, two, or more, depending on the number of cuts required on the soft rubber 100. When there is only one mounting slot 51, it can be arranged in the area directly opposite the cutter 22 on the top of the base plate 5, as needed. When the soft rubber 100 needs to be cut twice in different directions, taking cutting a cross in the center of the soft rubber 100 as an example, the number of mounting slots 51 is set to two, with the centers of the two mounting slots 51 overlapping and the two mounting slots 51 distributed perpendicularly. After the soft rubber 100 is cut once, the fixture 31 is manually moved to another mounting slot 51 for another cut, thus allowing for two cuts in different directions on the soft rubber 100. When the soft rubber 100 needs to be cut multiple times, the number of mounting slots 51 is set to multiple, the centers of multiple mounting slots 51 coincide, and the multiple mounting slots 51 are distributed in a circle with the center of the mounting slot 51 as the center. The spacing between adjacent mounting slots 51 is uniform. For example, a mounting slot 51 can be arranged by rotating at 45 degrees. When it is necessary to cut the soft rubber 100 in the corresponding direction, the jig 31 can be manually moved into different mounting slots 51.
[0041] The soft rubber cutting device in this application also includes multiple limiting posts 6, which can be hollow cylinders. The multiple limiting posts 6 are fixed to the top of the base plate 5 and distributed in different directions of the base plate 5. The height of the limiting posts 6 is the same as the height of the fixture 31. When the cutter 22 moves downwards to cut the soft rubber 100, after sliding down to a certain height, the bottom of the mounting plate 43 will abut against the top of the limiting post 6, at which point the cutter 22 cannot continue to move downwards. The limiting posts 6 are used to limit the downward distance of the cutter 22, preventing the cutter 22 from cutting through the soft rubber 100 and continuing to contact the support post 32, thus preventing damage to the cutter 22 and other tools.
[0042] In this application, the thickness of the end of the cutter 22 is 0.1 mm, and the thickness of the blade of the cutter 22 is 0.01 mm. Since the soft rubber cutting device of this application needs to achieve the effect of forming a closed slit after cutting the soft rubber 100, the blade of the cutter 22 must be extremely sharp. After the cutter 22 contacts the soft rubber 100 inside the fixture 31, the cutter 22 continues to move downwards, and the sharp blade squeezes the soft silicone product, causing a tearing slit in the product, thus achieving the effect of the slit closing itself without external force.
[0043] The soft rubber cutting device of this invention includes a fixture that wraps around the side of the soft rubber, and a cutter mounting piece and a support column that abut against the upper and lower parts of the soft rubber, respectively. Space is reserved for the soft rubber to deform during cutting, minimizing deformation. A slit is cut into the soft rubber without altering its original shape. When the cut needs to be opened, external force is used to create the slit. When the external force is removed, the slit closes automatically, forming a sealed slit and achieving a sealing effect.
[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
