Description

Technical Field

[0001] This utility model relates to the field of sponge production technology, and in particular to a ring-cutting device for stable cutting. Background Technology

[0002] Sponge is a three-dimensional porous polymer material. A sponge ring-cutting machine is a device used for cutting and processing sponges, mainly for cutting sponges into sheets of specific thickness and size. A stable ring-cutting device can ensure that there is no significant shaking during sponge cutting, which could lead to cutting errors.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Existing stable cutting ring cutting devices generally include structures such as a turntable, a support, and a cutting mechanism. Most existing cutting mechanisms cut the sponge with steel wire. However, after a long period of cutting, the steel wire will wear out or break. At this time, it is necessary to take the steel wire from the outside and fix it back to the cutting mechanism. This process is too troublesome. Moreover, after long-term use, the existing steel wire will be stretched, resulting in incomplete cutting. At the same time, the existing cutting mechanism is too cumbersome and cannot be quickly repaired or replaced after damage.

[0004] Therefore, those skilled in the art have provided a stable circumferential cutting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable circumferential cutting device. The device can tension the steel wire through a backup mechanism and quickly fix the steel wire to the device, reducing waiting time. The device can also quickly repair or replace the cutting structure through a replacement mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable circumferential cutting device, comprising a backup mechanism, a replacement mechanism, and a working mechanism. The backup mechanism includes a first block, a locking block is fixedly connected to the bottom of the first block, a first bolt is threadedly connected to the inner wall of the bottom of the locking block, and a rotating block is slidably connected to the outer wall of the bottom of the first bolt.

[0007] The replacement mechanism includes a second block, a second bolt is threaded to the inner wall of the bottom of the second block, an octagonal prism is fixedly connected to the bottom of the second bolt, and the working mechanism includes a bracket, a base frame, and gears, with a turntable rotatably connected to the top of the base frame.

[0008] Furthermore, a rotating ring is fixedly connected to the bottom of the center of the turntable. The bottom of the rotating ring is rotatably embedded in the bottom surface inside the bottom frame. The outer wall of the rotating ring near the top is rotatably connected to the inner wall of the top center of the bottom frame. The bottom of the bracket near the gear is fixedly connected to the bottom surface inside the bottom frame, and the bottom of the bracket away from the gear is fixedly connected to the ground.

[0009] Furthermore, a rack is fixedly connected to the outer wall of the turntable near the bottom, and the rack meshes with a gear.

[0010] Furthermore, a motor is fixedly connected to the bottom of the gear center, and the bottom end face of the motor is fixedly installed on the inner wall of the bottom frame away from the bracket.

[0011] Furthermore, an anti-slip pad is fixedly connected to the top of the turntable.

[0012] Furthermore, an electric push rod is fixedly connected to the inner wall at the center of the top of the bracket, and a pressure plate is fixedly connected to the output end of the electric push rod. The bottom of the pressure plate near the gear is fixedly connected to the top of the first block, and the bottom of the pressure plate away from the gear is fixedly connected to the top of the second block.

[0013] Furthermore, the outer wall of the pressure plate and the outer wall of the bracket are slidably connected.

[0014] Furthermore, a handle is fixedly connected to the bottom end of the rotating block away from the center, the top of the rotating block is movably connected to the bottom of the locking block, and the outer wall of the locking block is slidably connected to the outer wall of the bracket near the gear end.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a stable circumferential cutting device. A large amount of steel wire is wound around the outer wall of the rotating block. After the steel wire is worn or broken, the No. 1 bolt is removed without fixing the rotating block. Then, the steel wire on the outer wall of the rotating block is pulled and moved to the right to wrap around the outer wall of the octagonal prism. It is then fixed by electric welding. There is no need to find steel wire again, which can save maintenance time. When the steel wire is not tight enough and cannot be cut, the No. 1 bolt is rotated and the rotating block can be rotated. There is no need to remove the No. 1 bolt. Hold the handle and turn it to the left to make the excess steel wire wrap around the outer wall of the rotating block, making the steel wire tighter and easier to cut.

[0017] 2. The ring cutting device for stable cutting proposed in this utility model allows the rotating block to be removed and replaced by first removing the first bolt. Removing the second bolt allows the octagonal prism to be removed from the bracket. The rotating block and octagonal prism can be quickly removed from the bracket. The structure is simple and convenient, and it is easy to repair or replace quickly, reducing downtime. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Reference Figures 1-4 The present invention provides an embodiment of a stable circumferential cutting device, comprising a backup mechanism 1, a replacement mechanism 2, and a working mechanism 3. The backup mechanism 1 includes a first block 101, a locking block 102 fixedly connected to the bottom of the first block 101, a first bolt 104 threadedly connected to the inner wall of the bottom of the locking block 102, and a rotating block 103 slidably connected to the outer wall of the bottom of the first bolt 104. The replacement mechanism 2 includes a second block 201, a second bolt 202 threadedly connected to the inner wall of the bottom of the second block 201, and an octagonal prism 203 fixedly connected to the bottom of the second bolt 202. The working mechanism 3 includes a bracket 309, a base frame 301, and a gear 304. A turntable 306 is rotatably connected to the top of the base frame 301.

[0026] Specifically, a large amount of steel wire is wound around the middle of the rotating block 103. After the steel wire wears or breaks, the damaged steel wire is first cut off. Then, the first bolt 104 is removed but not fixed. The rotating block 103 is then pulled to the right, and the steel wire on the rotating block 103 is wound around the outer wall of the octagonal prism 203. It is then fixed by electric welding. The octagonal prism 203 has many ridges and is not a smooth curved surface, so the fixing effect is good. Then, the rotating block 103 and the first bolt 104 are reset and fixed by the first bolt 104. When the steel wire breaks, there is no need to find a new steel wire. To save time, when the wire is not tight enough to cut, simply rotate bolt 104 to allow the rotating block 103 to rotate without removing it. Hold handle 105 and rotate it counterclockwise to make the wire wrap around the outer wall of the rotating block 103, making it tighter and easier to cut. Then, fix the rotating block 103 with bolt 104. Rotate bolt 104 and remove it to remove the rotating block 103 for replacement. Rotate bolt 202 and remove it to remove the octagonal prism 203 from the bracket 309. The simple structure allows for easy maintenance and replacement of the cutting structure.

[0027] Reference Figures 1-4 A rotating ring 303 is fixedly connected to the bottom of the turntable 306 in the middle. The bottom of the rotating ring 303 is rotatably embedded in the bottom surface of the base frame 301. The outer wall of the rotating ring 303 near the top is rotatably connected to the inner wall of the top center of the base frame 301. The bottom of the bracket 309 near the gear 304 is fixedly connected to the bottom surface of the base frame 301. The bottom of the bracket 309 away from the gear 304 is fixedly connected to the ground. A rack 302 is fixedly connected to the outer wall of the turntable 306 near the bottom. The rack 302 meshes with the gear 304. A motor 305 is fixedly connected to the bottom center of the gear 304. The bottom surface of the motor 305 is fixedly located in the inner surface of the base frame 301 away from the bracket 309. The top of the turntable 306 is fixedly connected to an anti-slip pad 307. The inner wall of the top center of the bracket 309 is fixedly connected to an electric push rod 310. The output end of the electric push rod 310 is fixedly connected to a pressure plate 308. The bottom of the pressure plate 308 near the gear 304 is fixedly connected to the top of the first block 101. The bottom of the pressure plate 308 away from the gear 304 is fixedly connected to the top of the second block 201. The outer wall of the pressure plate 308 is slidably connected to the outer wall of the bracket 309. The bottom of the rotating block 103 away from the center is fixedly connected to a handle 105. The top of the rotating block 103 is movably connected to the bottom of the locking block 102. The outer wall of the locking block 102 is slidably connected to the outer wall of the bracket 309 near the gear 304.

[0028] Specifically, the bottom of the rotating ring 303 is rotatably embedded in the bottom surface of the bottom frame 301, and can rotate along the inner wall of the bottom surface of the bottom frame 301 to provide support for the turntable 306 and the rack 302. The rack 302 is circular. The anti-slip pad 307 can ensure that the sponge does not shake significantly when the turntable 306 moves or when the sponge is cut. The anti-slip pad 307 is made of rubber and can play an anti-slip role to prevent large displacements when the sponge is cut.

[0029] Working principle: The sponge is placed on top of the anti-slip mat 307. Then, an electrical signal from the controller starts the motor 305, which drives the gear 304 to rotate. The gear 304 causes the rack 302 to rotate the turntable 306 and the rotating ring 303 clockwise, moving the sponge towards the support 309. When the sponge reaches the bottom of the support 309, it stops moving. An electrical signal from the controller starts the electric push rod 310, which moves the pressure plate 308, the backup mechanism 1, and the replacement mechanism 2 downward. The sponge is cut by the steel wire located between the rotating block 103 and the octagonal prism 203. A large amount of steel wire can be wound around the middle position of the rotating block 103. After the steel wire is worn or broken, the damaged steel wire is cut off, and then the block is rotated. Bolt 104 moves it down without fixing the rotating block 103. Then the steel wire on the rotating block 103 is pulled to the right and wound around the outer wall of the octagonal prism 203. It is then fixed by electric welding. Then the rotating block 103 and bolt 104 are reset so that bolt 104 fixes the rotating block 103 again. There is no need to find steel wire again, which saves time. After cutting, the motor 305 can be restarted to make the turntable 306 rotate.

[0030] Secondly, when the wire is not tight enough to cut, the first bolt 104 can be rotated to allow the rotating block 103 to rotate without removing it. Then, hold the handle 105 and rotate it to the left to tighten the wire and make it easier to cut. After that, the first bolt 104 is reset to fix the rotating block 103. Rotating the first bolt 104 and removing it allows the rotating block 103 to be removed for replacement. Rotating the second bolt 202 and removing it allows the octagonal prism 203 to be removed from the bracket 309. The backup mechanism 1 and the replacement mechanism 2 can be quickly removed from the bracket 309 for maintenance or replacement, reducing downtime.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
