Description

Technical Field

[0001] This application relates to the field of rubber processing technology, specifically to a rubber strip cutting device. Background Technology

[0002] Rubber strips are made by hot-melting rubber and extruding it through an extruder. They have a wide range of uses and are applied in various industries. During the production process of rubber strips, they are usually cut by a cutting device to facilitate sorting.

[0003] A utility model patent with publication number CN220994540U discloses a rubber strip cutting device for rubber molding. The placement seat has a U-shaped cross-section, with open ends. One end of the placement seat is equipped with a support and a limiting mechanism. The support is located on the top of the placement seat, and a cutting mechanism is mounted on the support. A clamping mechanism is provided on the top surface of the placement seat. The limiting mechanism includes a limiting plate, a limiting plate, a screw, a side plate, and a bearing. The cutting mechanism includes a top plate, a hydraulic push rod, a bottom plate, and a blade. This utility model can effectively limit the weight of the rubber strip according to its length during operation, effectively ensuring the weight qualification rate during cutting, avoiding manual measurement, and improving cutting efficiency.

[0004] The device is equipped with a placement seat, and a limiting mechanism is set at one end of the placement seat. When the rubber strip is being cut, the operator rotates the screw to drive the limiting plate to slide, thereby adjusting the cutting length of the rubber strip. However, some flexible rubber strips sag between the placement seat and the limiting plate after extending out of the placement seat, which makes the length of the cut rubber strip prone to errors and the cutting accuracy is not high. Utility Model Content

[0005] To address the problem of low cutting accuracy in existing technologies, this utility model provides a rubber strip cutting device.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a tape cutting device, including a base with a storage groove on the base, a fixed frame fixedly installed on the top of the base, two sets of vertical plates slidably installed on the side wall of the storage groove on the base, a blade installed at the bottom of the vertical plate, a fixed rod fixedly installed at the top of the blade, a through hole provided on the vertical plate to match the fixed rod, a fixed plate installed at the top of the vertical plate, the top of the fixed rod connected and fixed to the fixed plate, a spring installed at the top of the vertical plate and sleeved on the fixed rod, the two ends of the spring abutting against the vertical plate and the fixed plate respectively, and a push plate installed below the fixed frame, the bottom of the push plate abutting against the top of the fixed plate;

[0008] It also includes a drive mechanism, which is mounted on the base;

[0009] It also includes a pressing mechanism, which is mounted on a fixed frame.

[0010] Preferably, the driving mechanism includes a motor, a screw, and a slider. The base has a mounting cavity, and the motor is fixedly mounted within the mounting cavity. The base has a sliding groove on the side wall of the receiving slot. The screw is located within the sliding groove and rotatably connected to the base. The screw has threaded sections on both sides in opposite directions. The motor output shaft is fixedly connected to one end of the screw. A set of sliders is fixedly mounted on each side of the vertical plate. The sliders are located within the sliding groove and threaded onto the screw. When the operator starts the motor in the mounting cavity, the motor drives the screw to rotate. This, in turn, drives the two sets of vertical plates to move synchronously closer or further apart via the opposite threaded sections on both sides of the screw, enabling convenient adjustment of the distance between the two sets of blades and ensuring cutting accuracy.

[0011] Preferably, the pressing mechanism includes an electric push rod, which is fixedly mounted on the top of the fixed frame. The output shaft of the electric push rod is fixedly connected to the top of the push plate. The operator presses the push plate by using the electric push rod to achieve synchronous pressing of the two sets of fixed plates and the blade, ensuring accurate cutting of the adhesive strip and improving cutting accuracy.

[0012] Preferably, the fixing rods are in multiple sets and spaced apart on the blade, and the lifting and lowering of the blade is limited at multiple points by the multiple sets of fixing rods to ensure the stability of the blade lifting and lowering.

[0013] Preferably, the base is provided with multiple sets of partitions at intervals at the bottom of the storage slot, and the blade is provided with a slot for fitting with the partitions. By dividing the storage slot again with partitions at the bottom of the storage slot, it is convenient to place multiple sets of adhesive strips in the storage slot at the same time for cutting, which improves cutting efficiency. The slots provided on the blade prevent the blade from colliding with the partitions and ensure the safety of the blade.

[0014] Preferably, the side wall of the storage groove is provided with scale lines along the length of the slide, which makes it convenient for staff to observe the cutting length.

[0015] Preferably, the height of the fixing rod above the vertical plate is equal to the height from the bottom of the blade to the bottom of the storage slot, so that when the bottom of the fixing plate abuts against the top of the vertical plate during the lifting and lowering process, the bottom of the blade is flush with the bottom of the storage slot, avoiding excessive collision between the blade and the bottom of the storage slot and ensuring the safety of the blade.

[0016] The advantages of adopting the above technical solution are:

[0017] This utility model includes a base with a storage slot. A fixing frame is fixedly mounted on the top of the base. Two sets of vertical plates are slidably mounted on the side wall of the storage slot. A blade is mounted at the bottom of the vertical plate, and a fixing rod is fixedly mounted on the top of the blade. The vertical plate has a through hole that matches the fixing rod. A fixing plate is mounted on the top of the vertical plate. The top of the fixing rod is connected and fixed to the fixing plate. A spring is mounted on the top of the vertical plate and is sleeved on the fixing rod. The two ends of the spring abut against the vertical plate and the fixing plate, respectively. A push plate is mounted below the fixing frame, and the bottom of the push plate abuts against the top of the fixing plate. By setting two sets of vertical plates, this device can drive the blade to slide, achieving precise adjustment of the cutting length and ensuring cutting accuracy. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 1-3As shown in the figure, this utility model discloses a tape cutting device, including a base 1, a driving mechanism and a pressing mechanism. The base 1 is provided with a storage groove 101, and a fixing frame 2 is fixedly provided on the top of the base 1. Two sets of vertical plates 3 are slidably provided on the side wall of the storage groove 101 on the base 1. A blade 4 is provided at the bottom of the vertical plate 3, and a fixing rod 401 is fixedly provided at the top of the blade 4. A through hole 301 is provided on the vertical plate 3 to match the fixing rod 401. A fixing plate 402 is provided at the top of the vertical plate 3. The top end of the fixing rod 401 is connected and fixed to the fixing plate 402. A spring 403 is provided at the top of the vertical plate 3 and is sleeved on the fixing rod 401. The two ends of the spring 403 abut against the vertical plate 3 and the fixing plate 402 respectively. A push plate 6 is provided below the fixing frame 2. The bottom of the push plate 6 abuts against the top of the fixing plate 402. The driving mechanism is provided on the base 1, and the pressing mechanism is provided on the fixing frame 2.

[0025] In at least one embodiment, the driving mechanism includes a motor 7, a screw 701, and a slider 302. The base 1 has an installation cavity, and the motor 7 is fixedly installed in the installation cavity. The base 1 has a sliding groove 102 on the side wall of the receiving groove 101. The screw 701 is located in the sliding groove 102 and is rotatably connected to the base 1. The two sides of the screw 701 have threaded sections in opposite directions. The output shaft of the motor 7 is fixedly connected to one end of the screw 701. A set of sliders 302 are fixedly installed on both sides of the vertical plate 3. The sliders 302 are located in the sliding groove 102 and are threaded onto the screw 701. When the operator starts the motor 7 in the installation cavity, the motor 7 drives the screw 701 to rotate. Then, through the opposite threaded sections on both sides of the screw 701, the two sets of vertical plates 3 move closer or further apart synchronously, realizing convenient adjustment of the distance between the two sets of blades 4 and ensuring cutting accuracy.

[0026] In at least one embodiment, the pressing mechanism includes an electric push rod 5, which is fixedly mounted on the top of the fixed frame 2. The output shaft of the electric push rod 5 is fixedly connected to the top of the push plate 6. The operator presses the push plate 6 by using the electric push rod 5 to achieve synchronous pressing of the two sets of fixed plates 402 and the blade 4, ensuring accurate cutting of the adhesive strip and improving cutting accuracy.

[0027] In at least one embodiment, the number of fixing rods 401 is multiple sets and they are spaced apart on the blade 4. The lifting and lowering of the blade 4 is limited at multiple points by the multiple sets of fixing rods 401 to ensure the stability of the lifting and lowering of the blade 4.

[0028] In at least one embodiment, the base 1 is provided with multiple sets of partitions 103 at intervals at the bottom of the storage slot 101, and the blade 4 is provided with a slot 404 that matches the partitions 103. By further dividing the storage slot 101 by the partitions 103 at the bottom of the storage slot 101, it is convenient to place multiple sets of adhesive strips in the storage slot 101 at the same time and cut them, thereby improving the cutting efficiency. The slot 404 provided on the blade 4 prevents the blade 4 from colliding with the partitions 103 and ensures the safety of the blade 4.

[0029] In at least one embodiment, the sidewall of the storage groove 101 is provided with scale lines along the length of the slide groove 102, which makes it convenient for staff to observe the cutting length.

[0030] In at least one embodiment, the height of the fixing rod 401 above the vertical plate 3 is equal to the height from the bottom of the blade 4 to the bottom of the storage groove 101, so that when the bottom of the fixing plate 402 abuts against the top of the vertical plate 3 during the lifting and lowering process, the bottom of the blade 4 is flush with the bottom of the storage groove 101, thus avoiding excessive collision between the blade 4 and the bottom of the storage groove 101 and ensuring the safety of the blade 4.

[0031] When cutting adhesive strips, the operator places the adhesive strip to be cut flat in the storage slot 101 on the base 1. Then, the operator drives the two sets of vertical plates 3 to slide in the storage slot 101 through the drive mechanism, thereby causing the vertical plates 3 to slide the blades 4 at the bottom. This allows for adjustment of the distance between the two sets of blades 4, ensuring convenient adjustment for different cutting lengths. The operation is convenient. Once the cutting length is reached, the operator stops. Then, the operator presses down the push plate 6 at the bottom of the fixing frame 2 through the pressing mechanism. The push rod abuts against the fixing plate 402, pushing the blades 4 at the bottom of the vertical plate 3 to descend. Finally, the two sets of blades 4 cut the adhesive strip simultaneously, improving the cutting accuracy. After cutting, the pressing mechanism releases the pressure on the push plate 6, and the fixing plate 402 rises under the push of the spring 403, causing the blades 4 to rise. The operator can then remove the cut adhesive strip. The operation is convenient.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
