[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In actual use, because the positioning mechanism is fixed, it can only be used with sealing strips of a single specification (width and thickness). When producing products of different specifications, different models of cutting devices need to be replaced, which reduces the work efficiency of the workers.

[0022] In view of this, the present invention provides a cutting device for the production and processing of sealing strips, which solves the problem that in actual use, due to the fixed positioning mechanism, it can only be adapted to sealing strips of a single specification (width and thickness). When producing products of different specifications, it is necessary to change to different models of cutting devices, which leads to a decrease in the work efficiency of the workers.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figures 1-4 It is known that a cutting device for producing and processing sealing strips includes a worktable 1, with two positioning wheels 2 mounted on the top of the worktable 1 and a cutter 4 disposed between the two positioning wheels 2. The cutting device for producing and processing sealing strips also includes a quick-release structure 3, an adjustment component 5, and a traction component 6. Two sets of quick-release structures 3 are provided, respectively installed on the outer walls of the two positioning wheels 2 and on the top of the worktable 1; the adjustment component 5 is installed above the quick-release structure 3; and the traction component 6 is installed on one side of the top of the worktable 1. The positioning wheels 2 are replaced by the quick-release structure 3, the position of the cutter 4 is adjusted by the adjustment component 5, and the traction component 6 drives the sealing strip to move.

[0025] In the specific implementation process, it is worth noting that the workbench 1 is made of high-strength cast iron and has a rectangular flat structure. The four corners of the bottom are fixed with leveling feet. The level of the workbench 1 can be adjusted by rotating the feet to avoid affecting the cutting accuracy due to the tilt of the table surface. The top surface of the workbench 1 is milled and polished to ensure that the positioning wheel 2, traction component 6 and other components are installed flat. The sealing strip waste generated by cutting can be cleaned into the collection box on one side of the workbench 1 to reduce on-site accumulation. The positioning wheel 2 is provided with two parts, one above the other, and the shape of the positioning wheel 2 is limited according to the shape of the sealing strip. The positioning wheel 2 can be replaced according to the quick-release structure 3. At the same time, the model of the cutter 4 is also replaced according to the model of the sealing strip. The sealing strip moves under the drive of the traction component 6 to facilitate the cutting of the sealing strip by the cutter 4. Under the drive of the adjustment component 5, the distance between the cutters 4 can be adjusted to make it suitable for different sealing strips.

[0026] Furthermore, the quick-release structure 3 includes a mounting shell 31, of which two are provided, fixedly connected to the top of the workbench 1 and positioned above the workbench 1; a threaded rod 32 is rotatably connected to the inner wall of the mounting shell 31 via a bearing; a slider 33 is slidably engaged with the inner wall of the mounting shell 31, and its inner wall is threadedly connected to the outer wall of the threaded rod 32; a mounting plate 34 is fixedly connected to the outer wall of the slider 33; a connecting rod 35 is rotatably connected to the inner wall of the mounting plate 34 via a bearing; a rhombus-shaped block 36 is fixedly connected to the outer wall of the connecting rod 35 and inserted into the outer wall of the positioning wheel 2; and an adjustment device 37 is installed on the top of the upper mounting shell 31; wherein, through the cooperation of the threaded rod 32 and the slider 33, the mounting plate 34 drives the connecting rod 35 to move, inserting the rhombus-shaped block 36 into the outer wall of the positioning wheel 2, the mounting shell 31 supports the threaded rod 32, and the adjustment device 37 adjusts the height of the positioning wheel 2;

[0027] In the specific implementation process, it is worth noting that the same diamond-shaped groove as the diamond block 36 is opened on the side of the positioning wheel 2. After the positioning wheel 2 is fitted onto the outer wall of the diamond block 36, the connecting rod 35 will drive the positioning wheel 2 to rotate synchronously. The inner wall of the slider 33 is provided with the same internal thread as the outer wall of the threaded rod 32. When the operator uses the handle to drive the threaded rod 32 to rotate, the threaded connection between the threaded rod 32 and the slider 33 will cause the slider 33 to drive the mounting plate 34 to move at the bottom of the mounting shell 31. The mounting plate 34 will drive the connecting rod 35 and the diamond block 36 to move out from the side of the positioning wheel 2, and place the appropriate positioning wheel 2 between the mounting plates 34. Then, the threaded rod 32 will be rotated in the opposite direction, so that the mounting plate 34 will drive the connecting rod 35 and the diamond block 36 to insert into the inner wall of the positioning wheel 2, fixing the positioning wheel 2. This makes it convenient to replace the positioning wheel 2, makes it stable when limiting different sealing strips, and ensures that it will not deviate when cutting.

[0028] Understandably, the upper and lower positioning wheels 2 are matched and have grooves or protrusions machined on their surfaces to accommodate the sealing strip. In this way, the upper and lower positioning wheels 2 can fit into the top and bottom of the sealing strip to form an effective limit. Multiple sets of positioning wheels 2 should be set to correspond to sealing strips of conventional shapes and specifications to improve adaptability. The cutter 4 is set on the edge of the positioning wheel 2 so that burrs and excess parts of the sealing strip edge can be cut to achieve edge trimming of the sealing strip.

[0029] Furthermore, the adjustment device 37 includes a straight plate 371, which is fixedly connected to the top of the mounting shell 31; a limiting block 372 is fixedly connected to the outer wall of the straight plate 371; and a vertical plate 373 is fixedly connected to the top of the worktable 1, with its inner wall slidably engaged with the outer wall of the limiting block 372. The straight plate 371 adjusts the height of the positioning wheel 2 through the cooperation of the limiting block 372 and the vertical plate 373.

[0030] In the specific implementation process, it is worth noting that a sliding groove is provided on the side of the vertical plate 373 to allow the limiting block 372 to move within its inner wall. Furthermore, the end of the limiting block 372 extending to the outside of the vertical plate 373 is bolted to the outer wall of the vertical plate 373. This facilitates the adjustment of the height of the straight plate 371. During adjustment, the straight plate 371 is moved upwards, and the sealing strip is placed on top of the positioning wheel 2 located below, making them fit together. The bolts on the outer wall of the limiting block 372 are then loosened, allowing the positioning wheel 2 to adhere to the top of the sealing strip under the action of gravity, forming a two-way connection. The positioning wheel 2 clamps the sealing strip. At this time, the bolts on the outer wall of the limiting block 372 are tightened, and the limiting block 372 is fixed to the outer wall of the vertical plate 373, thereby fixing the positioning wheel 2 located above. This fixes the sealing strip with the straight plate 371 and the positioning wheel 2. After it is fixed, the sealing strip moves towards the traction component under the traction of the traction component, so that the cutter 4 cuts the edge of the sealing strip from the side. Of course, the part between the traction component and the positioning wheel 2 is not cut. The sealing strip can be fixed in the opposite direction for secondary cutting. In this way, the purpose of cutting all the edges of the sealing strip is achieved.

[0031] Example 2: From Figures 1-4 It is known that the adjustment component 5 includes a bracket 51, which is fixedly connected to the outer wall of the mounting plate 34; the moving block 52 is slidably engaged with the inner wall of the bracket 51, and its top is fixedly connected to the bottom of the cutter 4; wherein, the position of the cutter 4 is adjusted by the cooperation of the bracket 51 and the moving block 52.

[0032] In the specific implementation process, it is worth noting that a slot is provided on the top of the bracket 51, and the slot and the slot at the bottom of the moving block 52 are both trapezoidal blocks. This can ensure the stability of the moving block 52 when it moves, and also ensure the stability of the cutter 4 when it is working. At the same time, a bolt can be installed on the top of the moving block 52, and the bolt can pass through the moving block 52 so that it can be pressed against the top of the bracket 51, thus ensuring stability when fixing the cutter 4.

[0033] Furthermore, the traction assembly 6 includes a traction wheel 61, which is mounted on one side of the top of the workbench 1; a mounting frame 62 is rotatably connected to the outer wall of the traction wheel 61 via a bearing and is fixedly connected to the top of the workbench 1; a servo motor 63 is fixedly connected to the outer wall of the mounting frame 62, and its output end is fixedly connected to the traction wheel 61 through a bearing at one end of the mounting frame 62; a pressure wheel 64 is disposed above the traction wheel 61; a mounting frame 65 is rotatably connected to the outer wall of the pressure wheel 64 via a bearing and is slidably engaged with the outer wall of the mounting frame 62; a lead screw 66 is rotatably connected to the top of the mounting frame 65 via a bearing, and its upper outer wall is threadedly connected to the inner wall of the mounting frame 62; wherein, through the cooperation of the lead screw 66 and the mounting frame 62, the mounting frame 65 drives the pressure wheel 64 to rise and fall, and the servo motor 63 and the traction wheel 61 drive the sealing strip to move;

[0034] In the specific implementation process, it is worth noting that the surface of the traction wheel 61 is patterned, which increases the friction between the traction wheel 61 and the sealing strip. At the same time, under the pressure of the pressure wheel 64, the traction wheel 61 moves the sealing strip more stably. The servo motor 63 drives the traction wheel 61 to rotate, causing the sealing strip to move and making the cutter 4 cut the sealing strip stably. When tractioning sealing strips of different thicknesses, the screw 66 is rotated, causing the mounting frame 65 to drive the pressure wheel 64 to press against the sealing strip, making it convenient for the traction assembly 6 to traction different sealing strips. In addition, a groove is provided on the side of the mounting frame 62 to ensure the stability of the mounting frame 65 during lifting. The model of the servo motor 63 is not limited, as long as it meets the actual use requirements.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
