Description

Technical Field

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

[0002] Pearl cotton, also known as polyethylene foam, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles generated by the physical foaming of low-density polyethylene resin, overcoming the shortcomings of ordinary foam such as fragility, deformation, and poor resilience. It has many advantages such as water and moisture resistance, shock absorption, sound insulation, heat insulation, good plasticity, high toughness, recyclability, environmental protection, and strong impact resistance.

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0021] Reference Figures 1-6 As shown, a pearl cotton cutting device includes: a conveyor belt 101 disposed within a workbench 100 for conveying pearl cotton; an installation roller 102 provided at one end of the workbench 100; a cutting head 103 vertically mounted on the workbench 100 via a cutting mechanism 200; and an anti-deviation mechanism 400 located in front of the cutting head 103 on the workbench 100 for limiting the lateral position of the pearl cotton. The cutting mechanism 200 includes: a first mounting frame 201 slidably mounted on a workbench 100, wherein the first mounting frame 201 is driven by a driving component to raise and lower the cutting head 103 to cut the pearl cotton, and the workbench 100 is provided with an adjustment component 300 for limiting the position of the first mounting frame 201 so as to cut pearl cotton of different sizes. The adjustment component 300 includes: a stop block 303 slidably mounted on the workbench 100 by a moving component, and a pointer block 306 that cooperates with the stop block 303 is fixedly provided on the side of the first mounting frame 201.

[0022] In use, according to the required cutting size of the pearl cotton, the position of the stop block 303 on the worktable 100 is adjusted by the moving parts. After adjustment, the pointer block 306 cooperates with the stop block 303 to indicate and lock the position of the first mounting frame 201, ensuring that the cutting head 103 is in the appropriate cutting position. The pearl cotton roll is placed on the mounting roller 102, and one end of the pearl cotton is conveyed forward by the conveyor belt 101. When passing the anti-deviation mechanism 400, the anti-deviation mechanism 400 limits the left and right positions of the pearl cotton to ensure that the pearl cotton moves forward in a straight line without deviation during the conveying process. When the pearl cotton is conveyed to below the cutting head 103, the drive unit is activated, driving the cutting head 103 to descend and cut the pearl cotton. After cutting, the drive unit drives the cutting head 103 to rise and reset, and the conveyor belt 101 continues to run, conveying the cut pearl cotton forward to complete the discharge.

[0023] Reference Figure 4 As shown, the driving component includes: a rotating shaft 202 rotatably mounted on a first mounting bracket 201, a plurality of eccentric wheels 204 fixedly sleeved at intervals on the rotating shaft 202, a cam 205 rotatably mounted on each eccentric wheel 204 via a bearing, and a mounting bracket 206 slidably mounted on the first mounting bracket 201, a limiting groove 207 for sliding of the mounting bracket 206 being provided on the inner side wall of the first mounting bracket 201, the cam 205 being hinged to the mounting bracket 206, and a first motor 203 with an output shaft horizontally mounted on the first mounting bracket 201 and its top end fixedly connected to the rotating shaft 202.

[0024] In the above scheme, when it is necessary to cut the pearl cotton, the first motor 203 is started, and its output shaft drives the rotating shaft 202 to start rotating. During the rotation of the rotating shaft 202, multiple sets of eccentric wheels 204 fixedly sleeved on it rotate synchronously. The cam 205 on each eccentric wheel 204 rotates through the bearing and moves accordingly. Since the cam 205 is hinged to the mounting frame 206 and the mounting frame 206 is slidably set in the limiting groove 207 on the inner side wall of the first mounting frame 201, the rotation of the eccentric wheel 204 causes the cam 205 to generate eccentric motion, which in turn drives the mounting frame 206 to make up-down reciprocating linear motion in the limiting groove 207. When the mounting frame 206 moves up and down, the cutting head 103 fixed on the mounting frame 206 moves up and down accordingly. When the cutting head 103 descends, it cuts the pearl cotton located below it.

[0025] Reference Figures 5-6 As shown, horizontally arranged mounting slots 307 are respectively opened on the mutually spaced sides of the worktable 100. A second screw 308 is rotatably arranged in one set of mounting slots 307. A threaded block 309 that slides with the side wall of the mounting slot 307 is threaded on the second screw 308. The first mounting bracket 201 is fixedly installed on the threaded block 309. A drive motor 310 with a horizontally arranged output shaft and its top end fixedly connected to the second screw 308 is fixedly arranged on the worktable 100.

[0026] In the above scheme, when it is necessary to adjust the position of the first mounting bracket 201 on the worktable 100 to adapt to the cutting requirements of different sizes of pearl cotton, the drive motor 310 is started, and its output shaft drives the second screw 308 to start rotating. During the rotation of the second screw 308, since the threaded block 309 is threaded on the second screw 308 and slides with the side wall of the mounting groove 307, the threaded block 309 moves linearly along the mounting groove 307 under the thread drive of the second screw 308. The first mounting bracket 201, which is fixedly installed on the threaded block 309, moves synchronously with the movement of the threaded block 309, thereby realizing the adjustment of the position of the first mounting bracket 201 on the worktable 100.

[0027] Reference Figures 5-6 As shown, the movable component includes: a fixed block 301 fixedly disposed on the edge of the workbench 100, a first screw 302 threaded through the fixed block 301, a stop 303 rotatably disposed at one end of the first screw 302 via a bearing, a sliding groove 304 for the stop 303 to slide on the side of the workbench 100, and a throttle handle 311 fixedly disposed at one end of the first screw 302 away from the stop 303.

[0028] In the above scheme, when it is necessary to adjust the position of the stop block 303 according to the required cutting size of the pearl cotton, the operator turns the handle 311. The handle 311 drives the first screw 302 to rotate on the fixed block 301. Since one end of the first screw 302 is rotatably connected to the stop block 303 through a bearing, and the stop block 303 is slidably set in the slide groove 304 on the side of the worktable 100, the rotation of the first screw 302 causes the stop block 303 to move linearly in the slide groove 304, thereby realizing the adjustment of the position of the stop block 303. When the stop block 303 moves to the appropriate position, the handle 311 is stopped. At this time, the position of the stop block 303 is locked, which cooperates with the pointer block 306 on the side of the first mounting bracket 201 to limit the position of the first mounting bracket 201 and ensure that the cutting head 103 is in the predetermined cutting position.

[0029] Reference Figures 5-6 As shown, the workbench 100 has scale lines 305 on its side wall that work in conjunction with the stop block 303 and the pointer block 306.

[0030] In the above scheme, the scale line 305 provides an intuitive position reference for the stop block 303 and the pointer block 306. The operator can precisely adjust the position of the stop block 303 through the scale line 305, thereby achieving high-precision control of the pearl cotton cutting size and ensuring the consistency and accuracy of product size.

[0031] Reference Figure 3 As shown, the anti-deviation mechanism 400 includes: a second mounting frame 401 fixedly installed on the workbench 100; a slide rod 406 fixedly installed inside the second mounting frame 401; two sets of limiting blocks 405 slidably arranged at intervals on the slide rod 406; a second motor 402 with its output shaft vertically downward and its top end fixedly connected to a drive rod 403 fixedly installed on the second mounting frame 401; connecting rods 404 are respectively hinged to both ends of the drive rod 403; one end of each of the two sets of connecting rods 404 is respectively hinged to its corresponding limiting block 405; and multiple sets of rotating rollers 407 rotatably arranged on the inner sidewall of the limiting block 405, which contact the edge of the pearl cotton.

[0032] In the above scheme, based on the width of the pearl cotton, the second motor 402 is started, the drive rod 403 rotates with the output shaft, and the connecting rods 404 at both ends move accordingly, pushing the two sets of limiting blocks 405 to slide relative to each other on the slide rod 406, adjusting to a suitable distance so that their inner sidewalls contact the two side edges of the pearl cotton. When the pearl cotton is conveyed forward on the conveyor belt 101, its two side edges contact the limiting blocks 405, which restrict the left and right position of the pearl cotton to prevent it from deviating during the conveying process. As the pearl cotton moves forward, the rotating roller 407 rotates around its own axis under the action of friction, converting the sliding friction between the pearl cotton and the limiting blocks 405 into rolling friction. The rolling of the rotating roller 407 reduces the resistance during the conveying process of the pearl cotton, allowing the pearl cotton to pass through the anti-deviation mechanism 400 more smoothly, while avoiding wear or deformation of the pearl cotton edges due to excessive friction.

[0033] Reference Figures 1-2 As shown, the worktable 100 has a fixing and limiting mechanism 500 at one end away from the mounting roller 102 for fixing the end of the pearl cotton; wherein, The fixed limiting mechanism 500 includes: a third mounting frame 501 fixedly installed on the workbench 100 and away from the conveyor belt 101. A hydraulic rod 502 is fixedly installed on the third mounting frame 501. The output end of the hydraulic rod 502 is vertically downward and a pressure roller 504 that contacts the surface of the pearl cotton is fixedly installed on its bottom surface. A limiting rod 503 that slides through the third mounting frame 501 is fixedly connected to the pressure roller 504.

[0034] In the above scheme, when the front end of the pearl cotton is conveyed to the end of the worktable 100 away from the mounting roller 102, the hydraulic rod 502 is activated, and its output end drives the pressure roller 504 to move vertically downward. The pressure roller 504 descends to contact the surface of the pearl cotton and applies a certain pressure, fixing the end of the pearl cotton on the worktable 100. At the same time, the limit rod 503 descends synchronously with the pressure roller 504 and slides through the third mounting frame 501 to ensure that the movement trajectory of the pressure roller 504 is vertical and stable. With the end of the pearl cotton fixed, the cutting head 103 is activated to cut, avoiding cutting deviation caused by the movement of the pearl cotton during the cutting process.

[0035] In summary, the pearl cotton cutting device provided by this utility model allows the operator to rotate the handle 311 according to the required cutting size of the pearl cotton. This drives the stop block 303 to slide within the slide groove 304 via the first screw 302. The operator observes the relative positions of the stop block 303 and the pointer block 306 with the scale line 305 on the side wall of the worktable 100. When the pointer block 306 aligns with the scale line 305 corresponding to the required size, the operator stops rotating the handle 311, locks the position of the stop block 303, and starts the second motor 402 to drive the rod 403. As the output shaft rotates, the connecting rods 404 at both ends push the two sets of limiting blocks 405 to slide relative to each other on the slide rod 406, adjusting to a suitable distance so that the inner sidewall of the rotating roller 407 contacts the two side edges of the pearl cotton. The pearl cotton roll is placed on the mounting roller 102, and one end of the pearl cotton is pulled out, allowing it to pass through the anti-deviation mechanism 400 and extend onto the conveyor belt 101. The conveyor belt 101 is started. During the conveying process, the two side edges of the pearl cotton contact the rotating roller 407 on the inner sidewall of the limiting block 405. The rotating roller 407 rotates under the action of friction, turning the sliding friction into rotation. The friction is converted into rolling friction, reducing conveying resistance. Simultaneously, the limit block 405 restricts the left and right position of the pearl cotton to prevent deviation. The drive motor 310 is activated, and the second screw 308 rotates, causing the threaded block 309 to slide within the mounting groove 307. The first mounting bracket 201, fixed to the threaded block 309, moves accordingly until the pointer block 306 contacts the stop block 303. At this point, the cutting head 103 is in the predetermined cutting position. When the front end of the pearl cotton is conveyed to the end of the worktable 100 away from the mounting roller 102, the hydraulic rod 502 is activated, and its output... The end of the pressure roller 504 moves vertically downward, fixing the end of the pearl cotton on the worktable 100. The limit rod 503 descends synchronously with the pressure roller 504 and slides through the third mounting frame 501 to ensure that the movement trajectory of the pressure roller 504 is vertical and stable. The first motor 203 is started, and the rotating shaft 202 rotates to drive the eccentric wheel 204 and the cam 205 to move. The eccentric movement of the cam 205 causes the mounting frame 206 to move up and down in a straight line within the limit groove 207, driving the cutting head 103 to descend and cut the pearl cotton. After completion, the cutting head 103 rises and resets.
