Description

Technical Field

[0001] This utility model relates to the field of sound insulation cotton processing technology, and more specifically, to a sound insulation cotton cutting device. Background Technology

[0002] Sound insulation cotton is a material that absorbs sound wave energy through a porous structure or fiber layer, which can convert sound energy into heat energy and reduce noise transmission. In the production process of sound insulation cotton, it is often necessary to use cutting equipment to cut and trim the two sides of the sound insulation cotton and cut it at a fixed distance. For example, the positioning and cutting device for sound insulation cotton proposed in application number "CN202321333913.6" includes a cutting table and a cutting machine set above the cutting table. A horizontal guide rail is fixed between two legs at one end of the cutting table. A positioning ruler is horizontally distributed above the cutting table. The cutting machine is vertically installed inside the positioning ruler. A rotation self-locking component is provided between the positioning ruler and the cutting machine.

[0003] However, in the above technical solution, since there is only one blade to cut the burrs on the side of the sound insulation cotton, when it is necessary to cut the other side of the sound insulation cotton, it is often necessary to perform secondary processing. Secondary processing not only increases the production process and time cost and reduces production efficiency, but may also cause deviations in the secondary positioning process, affecting the cutting accuracy and resulting in inconsistent product quality. Therefore, we propose a sound insulation cotton cutting device to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a sound insulation cotton cutting device, which solves the problem that since there is only one blade for cutting the side burrs of the sound insulation cotton, when it is necessary to cut the other side of the sound insulation cotton, the sound insulation cotton often needs to be processed twice. This second processing not only increases the production process and time cost and reduces production efficiency, but may also cause deviations in the second positioning process, affecting the cutting accuracy and resulting in inconsistent product quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sound insulation cotton cutting device includes a workbench. A first support frame is installed in the middle of the upper surface of the workbench.

A motor is installed at the rear end of the movable groove, and the output end of the motor is connected to the second gear.

[0009] Preferably, a first cylinder is installed at the upper end of the first support frame, and the output end of the first cylinder moves through the interior of the first support frame and is connected to the support block.

[0010] Preferably, the rotating rod has a sliding groove at both the upper and lower ends, and a slider is movably installed inside the sliding groove. The ends of the sliders that are far apart from each other are connected to the annular blade. The two ends of the sliders are threaded with a clamping bolt, and the ends of the clamping bolts that are close to each other are in contact with the inner wall of the sliding groove.

[0011] Preferably, extension frames are installed on both sides of the support block, and auxiliary rollers are movably installed at the lower end of the inner side of the extension frames, with the auxiliary rollers in contact with the raw material.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) By setting two ring blades, the sound insulation cotton can be trimmed on both sides at the same time without secondary processing, which greatly shortens the production time, improves production efficiency, and reduces time costs. At the same time, the ring blades can be replaced according to the thickness of the raw material by using the tightening bolt and the slider. The spacing between the ring blades can also be controlled to accurately control the overall size of the raw material after trimming and cutting, effectively improving the cutting accuracy and ensuring the stability of product quality.

[0014] (2) In this utility model, the auxiliary roller will be adjusted in position synchronously with the rotating rod through the support block, so that the auxiliary roller and the rotating rod always keep the same horizontal line, so that the auxiliary roller can assist the material to move, and also limit the material to avoid the material from shifting during trimming and fixed-distance cutting, thereby improving the overall stability.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1 to 9 As shown in the figure, this utility model embodiment proposes a sound insulation cotton cutting device, including a workbench 1. A first support frame 2 is installed in the middle of the upper surface of the workbench 1. A trimming mechanism 3 is installed at the lower end of the inner part of the first support frame 2. A second support frame 4 is installed at one end of the upper surface of the workbench 1. A cutting blade 6 is movably installed at the lower end of the inner part of the second support frame 4. The cutting blade 6 and the workbench 1 are parallel vertically. A second cylinder 5 is installed at the upper end of the second support frame 4. The output end of the second cylinder 5 movably passes through the interior of the second support frame 4 and is connected to the cutting blade 6. The trimming mechanism 3 includes a support block 302. A placement hole 304 is provided through the lower end of the inner part of the support block 302. A transmission rod 303 is installed through the placement hole 304. Rotating rods 310 are respectively installed at the front and rear ends of the rod body of the transmission rod 303. The rotating rods 310 are in contact with the raw material. A ring blade 314 is respectively installed on the outer side of the rod body of each rotating rod 310 and at the end away from the support block 302.

[0027] like Figures 4 to 9As shown, in another embodiment of this utility model, limit plates 305 are respectively installed at the front and rear ends of the transmission rod 303. The limit plates 305 are engaged inside the placement hole 304. A first gear 306 is installed in the middle of the transmission rod 303. The first gear 306 is movably installed in the middle of the placement hole 304. The upper end of the support block 302 is provided with a movable groove 307, and the movable groove 307 is connected to the placement hole 304. A second gear 308 is movably installed at the front end of the movable groove 307. The second gear 308 is meshed with the first gear 306. A motor 309 is installed at the rear end of the movable groove 307. The output end of the motor 309 is connected to the second gear 308. A first cylinder 301 is installed at the upper end of the support frame 2. The output end of the first cylinder 301 moves through the interior of the first support frame 2 and is connected to the support block 302. The upper and lower ends of the rotating rod 310 are respectively provided with sliding grooves 311. Sliding blocks 312 are movably installed inside the sliding grooves 311. The ends of the sliding blocks 312 that are far apart from each other are respectively connected to the annular blade 314. The two ends of the sliding blocks 312 are respectively threaded with abutting bolts 313. The ends of the abutting bolts 313 that are close to each other are respectively in contact with the inner wall of the sliding groove 311. Extension frames 315 are installed on both sides of the support block 302. Auxiliary rollers 316 are movably installed at the lower end of the extension frames 315. The auxiliary rollers 316 are in contact with the raw material.

[0028] The user first selects the annular blade 314 according to the thickness of the raw material. After selection, the user uses the cooperation of the slider 312 and the groove 311 to fit the annular blade 314 onto the outside of the rotating rod 310. The user then adjusts the position of the annular blade 314 according to the width of the raw material. Finally, after adjusting the position of the annular blade 314, the user installs the locking bolt 313 using threads, ensuring a tight fit between the locking bolt 313 and the inner wall of the groove 311. This achieves tight positioning of the slider 312 and the annular blade 314, improving overall stability. After the annular blade 314 is installed, the first cylinder 301 pushes the support block 302 and the annular blade 314 downwards, adjusting the height of the annular blade 314. Finally, after adjustment... The motor 309 drives the second gear 308 to rotate, and the second gear 308 controls the transmission rod 303 to rotate through the meshing connection with the first gear 306. Finally, the transmission rod 303 drives the rotating rod 310 and the annular blade 314 to rotate, and the raw material can then move and be conveyed on the surface of the worktable 1. The auxiliary roller 316 guides the raw material toward the annular blade 314, allowing the annular blade 314 to begin trimming and cutting the sides of the raw material. At the same time, the rotating rod 310 also assists in pushing the raw material to move. The trimmed raw material moves to the lower end of the second support frame 4. After the raw material has moved a specified length, the second cylinder 5 pushes the cutting blade 6 to move downward, allowing the cutting blade 6 to begin cutting the raw material at a fixed distance, thus completing the processing of the raw material.

[0029] The extension frame 315 allows the auxiliary roller 316 to move synchronously with the rotating rod 310, enabling the auxiliary roller 316 to cooperate with the rotating rod 310 to assist the material in moving, improving the stability of the material during movement, and also limiting the two ends of the material to prevent bending or other issues during the cutting process.

[0030] The working principle of this sound insulation cotton cutting equipment:

[0031] In use, the user first selects the annular blade 314 according to the thickness of the raw material. After selection, the user uses the cooperation of the slider 312 and the groove 311 to fit the annular blade 314 onto the outside of the rotating rod 310. The user then adjusts the position of the annular blade 314 according to the width of the raw material. Finally, after adjusting the position of the annular blade 314, the user installs the locking bolt 313 using threads, ensuring a tight fit between the locking bolt 313 and the inner wall of the groove 311. This achieves tight positioning of the slider 312 and the annular blade 314, improving overall stability. After the annular blade 314 is installed, the first cylinder 301 pushes the support block 302 and the annular blade 314 downwards, adjusting the height of the annular blade 314. Finally, the height is adjusted... Once completed, the motor 309 drives the second gear 308 to rotate. The second gear 308 then controls the rotation of the transmission rod 303 through meshing with the first gear 306. Finally, the transmission rod 303 drives the rotating rod 310 and the annular blade 314 to rotate, allowing the raw material to move and be conveyed on the surface of the worktable 1. The auxiliary roller 316 guides the raw material toward the annular blade 314, allowing the annular blade 314 to begin trimming and cutting both sides of the raw material. At the same time, the rotating rod 310 also assists in moving the raw material. The trimmed raw material moves to the lower end of the second support frame 4. After the raw material has moved a specified length, the second cylinder 5 pushes the cutting blade 6 downward, allowing the cutting blade 6 to begin cutting the raw material at a fixed distance, thus completing the processing of the raw material.
