Description

Technical Field

[0001] The invention relates to the field of cutting for latex pad production, in particular to a cutting machine for latex pad production and a cutting method thereof. Background Art

[0002] Latex mats refer to rubber sap collected from rubber trees. Through exquisite technical processes combined with modern equipment and technology to carry out processes such as demolding, foaming, gelling, vulcanization, washing, drying, forming and packaging, they are produced into modern green dormitory products with multiple excellent properties suitable for high-quality and healthy sleep of the human body. Latex sponge is a porous rubber material with a pore structure of all or most of the pores connected, and a small number of non-connected pores. It is the type of latex product that consumes the most latex. It has the characteristics of high elasticity, vibration absorption, compression fatigue resistance, good load-bearing capacity, comfort and durability. During the production process of latex mats, it needs to be cut.

[0003] For example, a cutting machine for latex mattress production disclosed in Chinese patent CN218985072U places latex blocks on the surface of a conveyor belt, automatically conveys the latex blocks using the conveyor belt, and fixes them with the help of pressure rollers. This allows the latex blocks to be automatically cut during the conveying process while preventing the latex blocks from shifting, thereby improving the cutting yield and cutting quality of latex mattress blanks.

[0004] Although this structure can cut the latex pad, when cutting with the electric heating wire, the cut section of the latex pad is easily affected by the electric heating wire, and burns and turns black, affecting the effect of the finished latex pad. Therefore, we propose a latex mattress production cutting machine that can cut the latex pad while ensuring that the cut section will not burn and turn black, thereby improving the overall cutting effect of the latex pad. Summary of the Invention

[0005] The purpose of the present invention is to provide a cutting machine and a cutting method for latex pad production to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a cutting machine for latex pad production, comprising a placing plate, a supporting leg fixedly installed at the bottom of the placing plate, and a processing component arranged on the outside of the placing plate, the processing component comprising a cutting component arranged on the top surface of the placing plate, a clamping component arranged on the outside of the cutting component, a conveying component arranged on the outside of the clamping component, and the cutting component comprising a supporting frame fixedly installed at the bottom of the placing plate, a motor fixedly installed at one end of the supporting frame away from the bottom of the placing plate, a threaded rod fixedly installed at the output end of the motor, a first set of blocks being provided on the outer wall of the threaded rod, a first sliding groove being provided on the outer wall of the first set of blocks, and the first sliding groove being provided on the outer wall of the first sliding groove. The cam is fixedly mounted on one side of the cam and is provided with a first spring, and the cam is fixedly mounted on the other side of the cam, and the cam is fixedly mounted on the other side of the cam.

[0007] According to the above technical solution, the clamping assembly includes a fixed block fixedly installed on the outer wall of the first set of blocks, a sliding rod is slidingly arranged inside the fixed block, a second spring is provided on the outer wall of the sliding rod, a pressure plate is fixedly installed on the end of the sliding rod, an inclined groove is provided on the side of the fixed block close to the first set of blocks, a sliding column is slidingly arranged inside the inclined groove, a clamping rod is fixedly installed on the outer wall of the sliding column, a sliding block is fixedly installed on the end of the clamping rod away from the sliding column, a fourth sliding groove is provided on the top surface of the placement plate, and the sliding block is slidably arranged with the fourth sliding groove.

[0008] According to the above technical solution, the conveying assembly includes a second hinged block fixedly installed on the outer wall of the fixed block, the second hinged block is hingedly connected to a connecting plate inside, the connecting plate is fixedly installed with a hook on one end away from the second hinged block, the placement plate is rotatably connected to a roller inside, the outer wall of the roller is provided with a conveyor belt, and the outer wall of the conveyor belt is provided with a slot.

[0009] According to the above technical solution, the outer wall of the threaded rod is threadedly sleeved with the inner thread of the first set of blocks, and the inner wall of the first set of blocks is slidably arranged with the outer wall of the limit rod. Under its limit, when the threaded rod rotates, it drives the first set of blocks to move, and the outer wall of the limit plate is slidably arranged with the inner wall of the first sliding groove opened on the outer wall of the first set of blocks. When the extrusion rod fixedly installed on the outer wall of the support plate is squeezed, the cutting knife pushes the limit plate to slide inside the first sliding groove, thereby making the cutting knife produce a vibration cutting effect.

[0010] According to the above technical solution, the second sliding groove sliding setting opened on the outer wall of the cutting knife and the outer wall of the second set of blocks is used to make the cutting knife slide more stably inside the second sliding groove when the extrusion rod set outside the cutting knife is squeezed by the extrusion block, thereby improving the cutting accuracy. The third sliding groove sliding setting opened on the extrusion rod and the outer wall of the vertical plate is used to make the extrusion rod slide inside the third sliding groove when the cutting knife drives the extrusion rod to move down to the third sliding groove, so that the support plate is deflected to the support state under the action of the hinge.

[0011] According to the above technical solution, there are two first springs, which are symmetrically distributed about the center line of the limit plate. When the cutting knife is squeezed, it slides toward the inside of the first slide groove to squeeze the first spring. When the cutting knife is not squeezed, it slides toward the outside of the first slide groove under the elastic action of the first spring.

[0012] According to the above technical solution, the sliding rod is slidingly arranged inside the fixed block, the bottom of the fixed block contacts the end of the second spring, and the end of the second spring away from the fixed block contacts the top surface of the pressure plate, so that when the fixed block moves downward, the pressure plate contacts the surface of the latex pad, and when the fixed block continues to move downward, the second spring is squeezed, so that the second spring is squeezed against the top surface of the pressure plate, so that the pressure plate continues to apply pressure to the top surface of the latex pad.

[0013] According to the above technical solution, the sliding column and the inclined groove opened on the outer wall of the fixed block are slidingly arranged, and the sliding block fixedly installed at one end of the clamping rod away from the sliding column and the fourth sliding groove opened on the top surface of the placement plate are slidingly arranged. When the fixed block moves downward, the inner wall of the inclined groove squeezes the outer wall of the sliding column, so that the sliding column drives the clamping rod to slide in opposite directions, so that the outer wall of the clamping rod contacts the side wall of the latex pad, thereby avoiding the tension deformation of the latex pad affecting the cutting effect.

[0014] According to the above technical solution, there are two hooks, which are symmetrically distributed about the center line of the conveyor belt. One end of the hook is provided with an inclined surface, so that when the hook moves away from the first set of blocks, the inclined surface of the hook slides and squeezes against the inner wall of the slot, so that the hook and the slot are no longer engaged. There are several slots, which are equidistantly opened on the outer wall of the conveyor belt. The slots are divided into two groups, which are symmetrically distributed about the center line of the conveyor belt. When conveying latex pads, the symmetrical engagement of the hooks makes the conveying more stable.

[0015] A latex pad cutting method comprising the following steps:

[0016] S1. When the latex pad is in the production process, it needs to be cut. The latex pad is placed on the top surface of the placement plate, the motor is started, and the threaded rod fixedly installed at the output end of the motor begins to rotate. Since another limit rod is provided for sliding inside the first set of blocks, when the threaded rod rotates, the first set of blocks with threaded sleeves on their outer walls can move downward. When the first set of blocks moves downward, the cutting knife sliding inside it also moves to cut the latex pad. Since the latex pad has elasticity, normal straight cutting effect is not good. When necessary, the cutting knife vibrates and cuts. When the cutting knife moves downward, the support plate hingedly connected to the inner side of the frame groove opened on the outer wall of the cutting knife also moves accordingly. The extrusion rod fixedly installed on the outer wall of the support plate slides and squeezes with the extrusion block fixedly installed on the outer wall of the vertical plate fixedly installed on the top surface of the placement plate. When the extrusion rod and the extrusion block are squeezed, the cutting knife moves away from the limit plate fixedly installed at one end of the extrusion block and slides inside the first slide groove opened on the outer wall of the first set of blocks, so that The limiting plate is squeezed by the first spring arranged inside the first slide groove. When the squeezing rod and the squeezing block are no longer squeezed, the cutting knife can slide left and right under the action of the first spring elasticity. When the squeezing rod and the squeezing block are squeezed, the cutting knife moves again, and the reciprocating motion allows the cutting knife to vibrate and cut the latex pad, thereby improving the cutting effect and avoiding the use of heating wire, which causes the cutting surface to be burned black and affects the appearance of the product. When the cutting knife continues to vibrate and cut downward, when cutting to the part close to the bottom of the latex pad, the latex pad that has been cut above will be squeezed inward, making the cutting resistance of the cutting knife greater. At this time, the squeezing rod fixedly installed on the outer wall of the support plate slides with the third slide groove opened on the outer wall of the vertical plate, so that the squeezing rod will expand the support plate as restricted by the third slide groove, so that the outer wall of the support plate contacts the inner wall cut by the latex pad, so that the support plate expands the inner wall cut by the latex pad, thereby reducing the force of the cutting knife being squeezed and clamped by the latex pad, making the cutting work smoother.

[0017] S2. When the latex pad needs to be cut, due to the elasticity of the latex pad, it needs to be limited in cutting to ensure the cutting accuracy. When the cutting work is in progress, the first set of blocks moves downward, so that the fixed block fixedly installed on the outer wall of the first set of blocks also moves accordingly, and the fixed block drives the sliding rod set inside it to move downward, so that the pressure plate fixedly installed at the end of the sliding rod also moves accordingly, so that the pressure plate contacts the surface of the latex pad. When the first set of blocks continues to move downward, the bottom of the fixed block squeezes the second spring set on the outer wall of the sliding rod, so that the second spring squeezes the top surface of the pressure plate, and continuously presses the pressure plate against the surface of the latex pad, so that the pressure plate clamps the top surface of the latex pad. When the top surface is under force, tension will occur on its side walls, and the side walls of the latex pad need to be limited. When the fixed block moves downward, the inclined groove opened on its outer wall squeezes the clamping rod away from the sliding column fixedly installed at one end of the slider, so that the sliding column slides inside the inclined groove. Under the action of the inclined groove, the slider fixedly installed at one end of the clamping rod away from the sliding column slides stably inside the fourth sliding groove opened on the top surface of the placement plate, so that the outer wall of the clamping rod contacts the side wall of the latex pad, and the tensioned side wall of the latex pad is gathered to the middle, so that the latex pad is in a stably clamped state when the cutting knife cuts, thereby making the cutting more accurate, reducing errors, and making the overall quality of the product more uniform.

[0018] S3. When the latex pad needs to be cut, the latex pad is placed on the top surface of the conveyor belt. When the cutting work is completed, the first set of blocks will move upward, so that the fixed block fixed on the outer wall of the first set of blocks will move accordingly, and the second hinged block fixed on the outer wall of the fixed block will also move upward. When the second hinged block moves upward, it drives the connecting plate hingedly connected inside it to move, and the hook fixed on the end of the connecting plate slides on the outer wall of the conveyor belt. When the hook slides to the inside of the slot opened on the outer wall of the conveyor belt, the hook is engaged with the slot, and the hook pulls the conveyor belt. Since the conveyor belt is connected to the inner rotation of the placement plate through the roller, the latex pad set on the top surface of the conveyor belt is The rubber pad also moves accordingly. When the first set of blocks moves up to the appropriate position, it stops moving and the latex pad is also transported to the designated cutting position. When the first set of blocks moves downward, the second hinged block also moves accordingly. The hook fixedly installed at the end of the connecting plate hingedly connected to the outer wall of the second hinged block contacts the inner wall of the slot, so that the inclined surface of the outer wall of the hook slides with the inner wall of the slot, so that the hook slides out of the slot, so that the hook follows the first set of blocks to move downward for operation. When the cutting is completed, the first set of blocks moves up, so that the end of the hook away from the inclined surface is engaged with the slot, and the latex pad set on the top surface of the conveyor belt is transported back and forth, thereby making the cutting work simpler and more convenient.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The cutting machine for latex pad production of the present invention is composed of a cutting assembly as one component. When the latex pad needs to be cut during the production process, the latex pad is placed on the top surface of the placement plate, the motor is started, and the threaded rod fixedly installed at the output end of the motor begins to rotate. Since another limit rod is provided for sliding inside the first set of blocks, when the threaded rod rotates, the first set of blocks with threaded sleeves on their outer walls can move downward. When the first set of blocks moves downward, the cutting knife sliding inside it also moves accordingly to cut the latex pad. Since the latex pad is elastic, the normal straight cutting effect is not good. When necessary, the cutting knife vibrates and cuts. When the cutting knife moves downward, the support plate hingedly connected to the inner side of the frame groove opened on the outer wall of the cutting knife is opened. It also moves accordingly, and the extrusion rod fixedly installed on the outer wall of the support plate slides and squeezes with the extrusion block fixedly installed on the outer wall of the vertical plate fixedly installed on the top surface of the placement plate. When the extrusion rod and the extrusion block are squeezed, the cutting knife is away from the limit plate fixedly installed at one end of the extrusion block and slides inside the first slide groove opened on the outer wall of the first set of blocks, so that the limit plate and the first spring arranged inside the first slide groove are squeezed. When the extrusion rod and the extrusion block are no longer squeezed, the cutting knife can slide left and right under the action of the elasticity of the first spring. When the extrusion rod and the extrusion block are squeezed, the cutting knife moves again, and the reciprocating motion allows the cutting knife to vibrate and cut the latex pad, thereby improving the cutting effect and avoiding the use of heating wire, which causes the cutting surface to be burned black and affects the appearance of the product.

[0021] 2. The cutting machine for latex pad production of the present invention is composed of a cutting assembly as one component. When the cutting knife continues to vibrate and cut downward, when it cuts to the position close to the bottom of the latex pad, the latex pad that has been cut above will be squeezed inward, making the cutting resistance of the cutting knife greater. At this time, the extrusion rod fixedly installed on the outer wall of the expansion plate slides with the third slide groove opened on the outer wall of the vertical plate, so that the extrusion rod expands the expansion plate with the restriction of the third slide groove, so that the outer wall of the expansion plate contacts the inner wall of the latex pad, so that the expansion plate expands the inner wall of the latex pad, thereby reducing the force of the cutting knife being squeezed and clamped by the latex pad, so that the cutting work is carried out more smoothly.

[0022] 3. The cutting machine for producing latex pads of the present invention is composed of a clamping assembly as one of its components. When the latex pad needs to be cut, due to the elasticity of the latex pad, it needs to be limited in cutting to ensure the cutting accuracy. When the cutting work is in progress, the first set of blocks moves downward, so that the fixed block fixedly installed on the outer wall of the first set of blocks also moves accordingly, and the fixed block drives the sliding rod slidingly arranged inside it to move downward, so that the pressure plate fixedly installed at the end of the sliding rod also moves accordingly, so that the pressure plate contacts the surface of the latex pad. When the first set of blocks continues to move downward, the bottom of the fixed block squeezes the second spring arranged on the outer wall of the sliding rod, so that the second spring squeezes the top surface of the pressure plate, and continuously pressurizes the pressure plate to the surface of the latex pad, so that the pressure plate presses the latex The top surface of the pad is clamped. When the top surface of the latex pad is subjected to force, tension will occur on its side walls, and the side walls of the latex pad need to be limited. When the fixed block moves downward, the inclined groove opened on its outer wall squeezes the clamping rod away from the sliding column fixedly installed at one end of the slider, so that the sliding column slides inside the inclined groove. Under the action of the inclined groove being tilted, the slider fixedly installed at one end of the clamping rod away from the sliding column slides stably inside the fourth sliding groove opened on the top surface of the placement plate, so that the outer wall of the clamping rod contacts the side wall of the latex pad, and the tensioned side wall of the latex pad is gathered toward the middle, so that the latex pad is in a stably clamped state when the cutting knife cuts, thereby making the cutting more accurate, reducing errors, and making the overall quality of the product more uniform.

[0023] 4. The cutting machine for producing latex mats of the present invention is composed of a conveying assembly as one component. When the latex mat needs to be cut, the latex mat is placed on the top surface of the conveyor belt. When the cutting work is completed, the first set of blocks will move upward, so that the fixed block fixedly installed on the outer wall of the first set of blocks will move accordingly, and the second hinged block fixedly installed on the outer wall of the fixed block will also move upward. When the second hinged block moves upward, it drives the connecting plate hingedly connected inside it to move, and the hook fixedly installed at the end of the connecting plate slides on the outer wall of the conveyor belt. When the hook slides to the inside of the slot opened on the outer wall of the conveyor belt, the hook is engaged with the slot, and the hook pulls the conveyor belt. Since the conveyor belt is connected to the inner rotation of the placement plate through the roller , so that the latex pad set on the top surface of the conveyor belt also moves accordingly. When the first set of blocks moves up to the appropriate position, it stops moving, and the latex pad is also transported to the designated cutting position. When the first set of blocks moves downward, the second hinged block also moves accordingly, and the hook fixedly installed at the end of the connecting plate hingedly connected to the outer wall of the second hinged block contacts the inner wall of the slot, so that the inclined surface of the outer wall of the hook slides with the inner wall of the slot, so that the hook slides out of the slot, so that the hook follows the first set of blocks to move downward for operation. When the cutting is completed, the first set of blocks moves upward, so that the end of the hook away from the inclined surface is engaged with the slot, and the latex pad set on the top surface of the conveyor belt is transported back and forth, thereby making the cutting work simpler and more convenient.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0037] A preferred embodiment of a latex pad production cutting machine provided by the present invention is as follows: Figures 1 to 10 Shown: A cutting machine for latex pad production, comprising a placement plate 1;

[0038] A supporting leg 2 is fixedly installed at the bottom of the placement plate 1;

[0039] The outer wall of the threaded rod 313 is provided with a first block 314, and the outer wall of the first block 314 is provided with a first sliding groove 315. The first sliding groove 315 is provided with a first spring 316 inside. The end of the first spring 316 away from the inner wall of the first sliding groove 315 is fixedly installed. A limit plate 317 is installed, and a cutting knife 318 is fixedly installed on the side of the limit plate 317 away from the first spring 316. The outer wall of the cutting knife 318 is provided with a frame groove 328, and the inner wall of the frame groove 328 is fixedly provided with a first hinge block 319. The outer wall of the first hinge block 319 is hingedly connected to the support plate 320, and the outer wall of the support plate 320 is fixedly provided with an extrusion rod 321. The top surface of the placement plate 1 is fixedly provided with a vertical plate 322, and the outer wall of the vertical plate 322 is fixedly provided with an extrusion block 323. The outer wall of the lower end of the vertical plate 322 is provided with a third sliding groove 327. The outer wall of the cutting knife 318 is slidably provided with a second set of blocks 324, and the outer wall of the second set of blocks 324 is provided with a second sliding groove 325. A limit rod 326 is slidably provided inside the second set of blocks 324.

[0040] In this embodiment, when the latex pad is produced, it needs to be cut. The latex pad is placed on the top surface of the placement plate 1, and the motor 312 is started. The threaded rod 313 fixedly installed at the output end of the motor 312 begins to rotate. Since another limiting rod 326 is slidingly provided inside the first set block 314, when the threaded rod 313 rotates, the first set block 314 with a threaded sleeve on its outer wall can move downward. When the first set block 314 moves downward, the cutting knife 318 slidingly provided inside it also moves accordingly to cut the latex pad. Since the latex pad has elasticity, normal The straight cutting effect is not good, and the cutting knife 318 vibrates when needed. When the cutting knife 318 moves downward, the support plate 320 hingedly connected to the inner side of the frame groove 328 opened on the outer wall of the cutting knife 318 also moves accordingly. The extrusion rod 321 fixedly installed on the outer wall of the support plate 320 slides and squeezes the extrusion block 323 fixedly installed on the outer wall of the vertical plate 322 fixedly installed on the top surface of the placement plate 1. When the extrusion rod 321 and the extrusion block 323 are squeezed, the cutting knife 318 is away from the limit plate 317 fixedly installed on one end of the extrusion block 323 and is in the first sliding groove 315 opened on the outer wall of the first set block 314 The first spring 316 of the first sliding groove 315 is pressed against the limiting plate 317. When the extrusion rod 321 and the extrusion block 323 are no longer squeezed, the cutting knife 318 can slide left and right under the elastic action of the first spring 316. When the extrusion rod 321 and the extrusion block 323 are squeezed, the cutting knife 318 moves again, and the reciprocating motion makes the cutting knife 318 vibrate and cut the latex pad, thereby improving the cutting effect and avoiding the use of heating wire, which makes the cutting surface burnt black and affects the appearance of the product. When the cutting knife 318 continues to vibrate and cut downwards, the latex pad is cut. When the rubber pad is close to the bottom, the latex pad that has been cut above will be squeezed inward, making the cutting resistance of the cutting knife 318 greater. At this time, the extrusion rod 321 fixedly installed on the outer wall of the expansion plate 320 slides with the third slide groove 327 opened on the outer wall of the vertical plate 322, so that the extrusion rod 321 is restricted by the third slide groove 327 to expand the expansion plate 320, so that the outer wall of the expansion plate 320 contacts the inner wall of the latex pad, so that the expansion plate 320 expands the inner wall of the latex pad, thereby reducing the force of the cutting knife 318 being squeezed and clamped by the latex pad, making the cutting work go more smoothly.

[0042] When the cam 332 is in the closed position, the first block 314 is in the closed position, and the second spring 333 is in the closed position, so that the cam 332 is pressed against the top of the cam 334, and the cam 334 is pressed against the top of the cam 334. When the top surface of the latex pad is under force, tension will occur on its side walls, and the side walls of the latex pad need to be limited. When the fixed block 331 moves downward, the inclined groove 335 opened on its outer wall squeezes the clamping rod 337 away from the sliding post 336 fixedly installed at one end of the slider 338, so that the sliding post 336 slides inside the inclined groove 335. Under the action of the inclined groove 335 being tilted, the clamping rod 337 is away from the sliding post 336 fixedly installed at one end and slides stably inside the fourth sliding groove 339 opened on the top surface of the placement plate 1, so that the outer wall of the clamping rod 337 contacts the side wall of the latex pad, and the tensioned side wall of the latex pad is gathered toward the middle, so that when the cutting knife 318 cuts, the latex pad is in a stably clamped state, thereby making the cutting more accurate, reducing errors, and making the overall quality of the product more uniform.

A conveyor belt 344 is provided on the outer wall of the roller 345, and a slot 346 is provided on the outer wall of the conveyor belt 344.

[0044] When the second hinge block 341 is moved upward, the connecting plate 342 hingedly connected thereto moves, and the hook 343 fixed at the end of the connecting plate 342 slides on the outer wall of the conveyor belt 344. When the hook 343 slides to the inside of the slot 346 opened on the outer wall of the conveyor belt 344, the hook 343 engages with the slot 346, and the hook 343 pulls the conveyor belt 344. Since the conveyor belt 344 is rotatably connected to the placement plate 1 through the roller 345, the conveyor belt 344 is When the first set of blocks 314 moves up to the appropriate position, it stops moving and the latex pad is also transported to the designated cutting position. When the first set of blocks 314 moves down, the second hinge block 341 also moves. The hook 343 fixedly installed at the end of the connecting plate 342 hingedly connected to the outer wall of the second hinge block 341 contacts the inner wall of the slot 346, so that the outer wall inclined surface of the hook 343 slides with the inner wall of the slot 346, so that the hook 343 slides out of the slot 346, so that the hook 343 follows the first set of blocks 314 to move down for operation. When the cutting is completed, the first set of blocks 314 moves up, so that the end of the hook 343 away from the inclined surface is engaged with the slot 346, and the latex pad set on the top surface of the conveyor belt 344 is transported back and forth, thereby making the cutting work simpler and more convenient.

[0045] Among them, the outer wall of the threaded rod 313 is threadedly sleeved with the inner wall of the first set block 314, and the inner wall of the first set block 314 is slidably arranged with the outer wall of the limit rod 326. Under its limit, when the threaded rod 313 rotates, it drives the first set block 314 to move, and the outer wall of the limit plate 317 is slidably arranged with the inner wall of the first slide groove 315 opened on the outer wall of the first set block 314. When the extrusion rod 321 fixedly installed on the outer wall of the support plate 320 is squeezed, the cutting knife 318 pushes the limit plate 317 to slide inside the first slide groove 315, so that the cutting knife 318 produces a vibration cutting effect.

[0046] Among them, the second sliding groove 325 opened on the outer wall of the cutting knife 318 and the outer wall of the second set block 324 is slidingly set, and is used to make the cutting knife 318 slide more stably inside the second sliding groove 325 when the extrusion rod 321 set outside the cutting knife 318 is squeezed by the extrusion block 323, thereby improving the cutting accuracy. The third sliding groove 327 opened on the outer wall of the extrusion rod 321 and the vertical plate 322 is slidingly set, and is used to make the extrusion rod 321 slide inside the third sliding groove 327 when the cutting knife 318 drives the extrusion rod 321 to move down to the third sliding groove 327, so that the expansion plate 320 is deflected to the expanded state under the action of the hinge.

[0047] Among them, there are two first springs 316, which are symmetrically distributed about the center line of the limit plate 317. When the cutting knife 318 is squeezed, it slides toward the inside of the first slide groove 315 to squeeze the first spring 316. When the cutting knife 318 is not squeezed, it slides toward the outside of the first slide groove 315 under the elastic action of the first spring 316.

[0048] The sliding rod 332 is slidably arranged inside the fixed block 331, the bottom of the fixed block 331 contacts the end of the second spring 333, and the end of the second spring 333 away from the fixed block 331 contacts the top surface of the pressure plate 334, so that when the fixed block 331 moves downward, the pressure plate 334 contacts the surface of the latex pad. When the fixed block 331 continues to move downward, the second spring 333 is squeezed, so that the second spring 333 is squeezed against the top surface of the pressure plate 334, so that the pressure plate 334 continues to apply pressure to the top surface of the latex pad. The sliding column 336 is slidably arranged with the inclined groove 335 opened on the outer wall of the fixed block 331, and the sliding block 338 fixedly installed at one end of the clamping rod 337 away from the sliding column 336 is slidably arranged with the fourth sliding groove 339 opened on the top surface of the placement plate 1. When the fixed block 331 moves downward, the inner wall of the inclined groove 335 squeezes the outer wall of the sliding column 336, so that the sliding column 336 drives the clamping rod 337 to slide in the opposite direction, so that the outer wall of the clamping rod 337 contacts the side wall of the latex pad, thereby preventing the tension deformation of the latex pad from affecting the cutting effect.

[0049] Among them, there are two hooks 343, which are symmetrically distributed about the center line of the conveyor belt 344. One end of the hook 343 is set with an inclined surface. When the hook 343 moves away from the first set of blocks 314, the inclined surface of the hook 343 slides and squeezes the inner wall of the slot 346, so that the hook 343 and the slot 346 are no longer engaged. There are several slots 346, which are equidistantly opened on the outer wall of the conveyor belt 344. The slots 346 are divided into two groups, which are symmetrically distributed about the center line of the conveyor belt 344. When conveying latex pads, the symmetrical engagement through the hooks 343 makes the conveying more stable.

[0050] A latex pad cutting method comprising the following steps:

[0051] S1. When the latex pad is produced, it needs to be cut. The latex pad is placed on the top surface of the placement plate 1, and the motor 312 is started. The threaded rod 313 fixedly installed at the output end of the motor 312 begins to rotate. Since another limiting rod 326 is provided for sliding inside the first set of blocks 314, when the threaded rod 313 rotates, the first set of blocks 314 with threaded sleeves on their outer walls can move downward. When the first set of blocks 314 moves downward, the cutting knife 318 provided for sliding inside thereof also moves accordingly to cut the latex pad. Since the latex pad has elasticity, normal straight cutting is possible. The effect is not good. When needed, the cutting knife 318 vibrates and cuts. When the cutting knife 318 moves downward, the support plate 320 hingedly connected to the inner side of the frame groove 328 opened on the outer wall of the cutting knife 318 also moves accordingly. The extrusion rod 321 fixedly installed on the outer wall of the support plate 320 slides and squeezes the extrusion block 323 fixedly installed on the outer wall of the vertical plate 322 fixedly installed on the top surface of the placement plate 1. When the extrusion rod 321 and the extrusion block 323 are squeezed, the cutting knife 318 is away from the limit plate 317 fixedly installed at one end of the extrusion block 323 and is inside the first slide groove 315 opened on the outer wall of the first set block 314 The first spring 316 provided inside the first slide groove 315 squeezes the limiting plate 317. When the squeezing rod 321 and the squeezing block 323 are no longer squeezing each other, the cutting knife 318 can slide left and right under the elastic action of the first spring 316. When the squeezing rod 321 and the squeezing block 323 are squeezed, the cutting knife 318 moves again. The reciprocating motion enables the cutting knife 318 to vibrate and cut the latex pad, thereby improving the cutting effect and avoiding the use of a heating wire, which causes the cutting surface to be burned black and affects the appearance of the product. When the cutting knife 318 continues to vibrate and cut downward, the latex pad is cut. When the pad is close to the bottom, the latex pad that has been cut above will be squeezed inward, making the cutting resistance of the cutting knife 318 greater. At this time, the extrusion rod 321 fixed on the outer wall of the expansion plate 320 slides with the third slide groove 327 opened on the outer wall of the vertical plate 322, so that the extrusion rod 321 is restricted by the third slide groove 327 to expand the expansion plate 320, so that the outer wall of the expansion plate 320 contacts the inner wall of the latex pad, so that the expansion plate 320 expands the inner wall of the latex pad, thereby reducing the force of the cutting knife 318 being squeezed and clamped by the latex pad, making the cutting work go more smoothly.

[0052] When the cam 332 is in the cam 334 position, the cam 334 is in the cam 336 position, and the cam 337 is in the cam 338 position, so that the cam 338 is pressed downwards, and the cam 339 is pressed downwards, so that the cam 339 is pressed downwards, and the cam 331 is pressed downwards, so that the cam 331 is pressed downwards, and the cam 332 is pressed downwards, so that the cam 339 is pressed downwards, and the cam 339 is pressed downwards, so that the cam 339 is pressed downwards, and the cam 339 is pressed downwards, so that the cam 339 is pressed downwards, When the top surface of the latex pad is under force, its side walls will be in tension, and the side walls of the latex pad need to be limited. When the fixed block 331 moves downward, the inclined groove 335 opened on its outer wall squeezes the clamping rod 337 away from the sliding post 336 fixedly installed at one end of the slider 338, so that the sliding post 336 slides inside the inclined groove 335. Under the action of the inclined groove 335 being tilted, the clamping rod 337 is away from the sliding post 336 fixedly installed at one end and slides stably inside the fourth sliding groove 339 opened on the top surface of the placement plate 1, so that the outer wall of the clamping rod 337 contacts the side wall of the latex pad, and the tensioned side wall of the latex pad is gathered toward the middle, so that when the cutting knife 318 cuts, the latex pad is in a stably clamped state, thereby making the cutting more accurate, reducing errors, and making the overall quality of the product more uniform.

[0053] When the second hinge block 341 is moved upward, it drives the connecting plate 342 hingedly connected thereto to move, and the hook 343 fixed at the end of the connecting plate 342 slides on the outer wall of the conveyor belt 344. When the hook 343 slides to the inside of the slot 346 opened on the outer wall of the conveyor belt 344, the hook 343 engages with the slot 346, and the hook 343 pulls the conveyor belt 344. Since the conveyor belt 344 is connected to the inner rotation of the placement plate 1 through the roller 345, the conveyor belt 344 is When the first set of blocks 314 moves up to the appropriate position, it stops moving and the latex pad is also transported to the designated cutting position. When the first set of blocks 314 moves down, the second hinge block 341 also moves. The hook 343 fixedly installed at the end of the connecting plate 342 hingedly connected to the outer wall of the second hinge block 341 contacts the inner wall of the slot 346, so that the outer wall inclined surface of the hook 343 slides with the inner wall of the slot 346, so that the hook 343 slides out of the slot 346, so that the hook 343 follows the first set of blocks 314 to move down for operation. When the cutting is completed, the first set of blocks 314 moves up, so that the end of the hook 343 away from the inclined surface is engaged with the slot 346, and the latex pad set on the top surface of the conveyor belt 344 is transported back and forth, thereby making the cutting work simpler and more convenient.

The latex pad is placed on the top surface of the placement plate (1), and the motor (312) is started. The threaded rod (313) fixedly installed at the output end of the motor (312) starts to rotate. Since another limiting rod (326) is provided inside the first set of blocks (314), when the threaded rod (313) rotates, the first set of blocks (314) with threaded sleeves on their outer walls can move downward. When the first set of blocks (314) moves downward, the cutting knife (318) provided inside the first set of blocks also moves accordingly to cut the latex pad. Since the latex pad is elastic, the normal straight cutting effect is not good. When necessary, the cutting knife (318) vibrates and cuts. When the cutting knife (318) moves downward, the support plate (320) hingedly connected to the inner side of the frame groove (328) opened on the outer wall of the cutting knife (318) also moves accordingly. The extrusion rod (321) fixedly installed on the outer wall of the support plate (320) and the extrusion block (323) fixedly installed on the outer wall of the vertical plate (322) fixedly installed on the top surface of the placement plate (1) slide and squeeze. When the extrusion rod (321) and the extrusion block (323) are squeezed, the cutting knife (318) is moved away from the limiting plate (317) fixedly installed at one end of the extrusion block (323) in the first sliding groove (317) opened on the outer wall of the first set block (314). 5) Internal sliding causes the limiting plate (317) to be squeezed with the first spring (316) provided inside the first slide groove (315). When the squeezing rod (321) and the squeezing block (323) are no longer squeezed, the cutting knife (318) can slide left and right under the elastic action of the first spring (316). When the squeezing rod (321) and the squeezing block (323) are squeezed, the cutting knife (318) moves again. The reciprocating motion allows the cutting knife (318) to vibrate and cut the latex pad, thereby improving the cutting effect and avoiding the use of a heating wire, which causes the cutting surface to be burned black and affects the appearance of the product. When the cutting knife (318) continues to vibrate and cut downward, the cutting When the latex pad is close to the bottom, the latex pad that has been cut above will be squeezed inward, making the cutting resistance of the cutting knife (318) greater. At this time, the squeezing rod (321) fixedly installed on the outer wall of the opening plate (320) slides with the third sliding groove (327) opened on the outer wall of the vertical plate (322), so that the squeezing rod (321) is restricted by the third sliding groove (327) to open the opening plate (320), so that the outer wall of the opening plate (320) contacts the inner wall of the latex pad, so that the opening plate (320) opens the inner wall of the latex pad, thereby reducing the force of the cutting knife (318) being squeezed and clamped by the latex pad, so that the cutting work is carried out more smoothly. S2. When the latex pad needs to be cut, since the latex pad has elasticity, it needs to be limited in cutting to ensure the cutting accuracy. When the cutting work is carried out, the first set of blocks (314) moves downward, so that the fixed block (331) fixedly installed on the outer wall of the first set of blocks (314) also moves accordingly. The fixed block (331) drives the sliding rod (332) slidingly arranged inside it to move downward, so that the pressure plate (334) fixedly installed at the end of the sliding rod (332) also moves accordingly, so that the pressure plate (334) contacts the surface of the latex pad. When the first set of blocks (314) continues to move downward, the bottom of the fixed block (331) squeezes the second spring (333) arranged on the outer wall of the sliding rod (332), so that the second spring (333) squeezes the top surface of the pressure plate (334), and continuously presses the pressure plate (334) against the surface of the latex pad, so that the pressure plate (334) clamps the top surface of the latex pad. When the top surface of the latex pad is subjected to force, tension will occur on its side wall, and the side wall of the latex pad needs to be limited. When the fixed block (331) moves downward, the inclined groove (335) opened on its outer wall squeezes the clamping rod (337) away from the sliding column (336) fixedly installed at one end of the slider (338), so that the slider (336) slides inside the inclined groove (335). Under the action of the inclined groove (335), the clamping rod (337) away from the sliding column (336) fixedly installed at one end slides stably inside the fourth sliding groove (339) opened on the top surface of the placement plate (1), so that the outer wall of the clamping rod (337) contacts the side wall of the latex pad, and the tensioned side wall of the latex pad is gathered toward the middle, so that when the cutting knife (318) cuts, the latex pad is in a stable clamping state, so that the cutting is more accurate, the error is reduced, and the overall quality of the product is more uniform. S3. When the latex pad needs to be cut, the latex pad is placed on the top surface of the conveyor belt (344).
