Description

Technical Field

[0001] This application relates to the field of sponge cutting technology, and in particular to a sponge cutting device. Background Technology

[0002] Sponge is a porous material with excellent water absorption, widely used in the automotive, battery, cosmetics, bra and underwear manufacturing, and high-end furniture manufacturing industries. During the production process, continuous sponge material is typically cut into strips of specific widths or lengths for further processing or use.

[0003] In related technologies, a sponge cutting device has been proposed, including a base, a hydraulic cylinder, a cutter, and a top cutter. The cutter is connected to the upper part of the base via the hydraulic cylinder for lifting, and the top cutter is positioned below the base corresponding to the cutter. When material is placed between the cutter and the top cutter, the hydraulic cylinder drives the cutter to descend, thereby achieving the cutting operation of the material.

[0004] Regarding the aforementioned technologies, the cutting blade and top blade settings can only achieve cutting of the sponge in one direction. When the sponge needs to be cut into blocks in both horizontal and vertical directions, it cannot be achieved by using only a fixed cutting blade, which increases the number of subsequent processing steps. Utility Model Content

[0005] To address the issue that fixed cutters alone cannot achieve the desired cutting of sponges in both horizontal and vertical directions, thus increasing subsequent processing steps, this application provides a sponge cutting device.

[0006] The sponge cutting device provided in this application adopts the following technical solution:

[0007] A sponge cutting device includes a conveying mechanism, a transverse cutting mechanism, and a longitudinal cutting mechanism. The longitudinal cutting mechanism is located at one end of the conveying mechanism along its length and is used to cut materials along the width of the conveying mechanism. The transverse cutting mechanism includes a mounting frame, a rotating rod, a rotary cutter, and a first rotary motor. The mounting frame is mounted on the conveying mechanism. The rotating rod is mounted on the mounting frame along the width of the conveying mechanism and is rotatably connected to the mounting frame around its own axis. The rotary cutter is spaced apart on the rotating rod. The first rotary motor is mounted on the mounting frame, and the rotating shaft of the first rotary motor is connected to the rotating rod.

[0008] By adopting the above technical solution, efficient cutting of sponges into blocks is achieved. The conveying mechanism is used to transport materials, while the transverse cutting mechanism and the longitudinal cutting mechanism are responsible for cutting in different directions, ensuring that the materials are accurately divided into blocks of the required size. Specifically, the transverse cutting mechanism drives the rotating rod to rotate through the first rotating motor, which drives the rotating cutter to cut the materials transversely, improving cutting efficiency and accuracy. The longitudinal cutting mechanism is located at one end of the conveying mechanism and is used to complete the longitudinal cutting of the materials. The two work together to achieve omnidirectional cutting function, which improves the problem that when sponges need to be cut into blocks in both transverse and longitudinal directions, it is impossible to achieve this with only a fixed cutter, which increases the number of subsequent processing steps.

[0009] Optionally, the rotating rod has an external thread on its peripheral wall, and the rotating cutter has an internal thread hole along its own axis. The rotating cutter is threaded to the external thread of the rotating rod through the internal thread hole, and fastening nuts are provided on both sides of the rotating cutter and threaded to the rotating rod.

[0010] By adopting the above technical solution, the rotary cutter and the rotating rod are detachably installed through a threaded connection, which makes it easy to replace or adjust the position of the rotary cutter according to actual needs; the setting of the fastening nut can effectively prevent the rotary cutter from loosening during operation, ensuring the stability of the cutting process and improving cutting accuracy and work efficiency.

[0011] Optionally, a pressure plate is slidably connected to the mounting frame along the vertical direction, and the mounting frame is provided with an adjustment component for adjusting the height of the pressure plate; a sliding groove is opened along the vertical direction of the pressure plate, the sliding groove extends along the length of the rotating rod, a movable rod is inserted vertically in the sliding groove, a crossbar is provided at the bottom of the movable rod, and at least two pressure rollers are rotatably connected to the bottom of the crossbar; a buffer spring is sleeved on the movable rod, one end of the buffer spring is connected to the crossbar, and the other end of the buffer spring is connected to the pressure plate.

[0012] By adopting the above technical solution, the pressure plate can slide vertically and its height can be adjusted by the adjustment component to adapt to materials of different thicknesses; the cooperation of the sliding groove and the movable rod enables the pressure roller to move stably vertically, while the setting of the buffer spring can provide appropriate downward pressure for the pressure roller, ensuring that the pressure roller is in close contact with the material surface, avoiding material deviation during the cutting process, and improving the cutting quality.

[0013] Optionally, a ratchet is coaxially connected to the pressure roller, and a pawl is rotatably connected to the crossbar, the pawl engaging with the ratchet teeth of the ratchet.

[0014] By adopting the above technical solution, a ratchet is coaxially connected to the pressure roller, and a pawl is rotatably connected to the crossbeam. The pawl is engaged in the ratchet teeth of the ratchet, which can effectively prevent the pressure roller from reversing when it contacts the sponge and applies pressure. This ensures that the material can only move along the conveying direction of the conveying mechanism, reduces the disturbance effect on the material when the rotary cutter cuts the material, and thus ensures the stable pressing effect of the pressure roller on the sponge and improves the material stability during the cutting process.

[0015] Optionally, the adjustment assembly includes a second rotating motor and a lead screw. The second rotating motor is vertically mounted on the mounting bracket, and the lead screw is connected to the rotating shaft of the second rotating motor. The lead screw passes through the pressure plate and is threadedly connected to the pressure plate.

[0016] By adopting the above technical solution, the height of the pressure plate can be precisely adjusted. Specifically, the second rotating motor drives the lead screw to rotate, and the rotational motion is converted into the vertical linear motion of the pressure plate by utilizing the threaded connection between the lead screw and the pressure plate. This design not only improves the convenience of adjustment, but also ensures the precise control of the pressure plate position, thereby adapting to the processing needs of materials of different thicknesses and improving the versatility and stability of the device.

[0017] Optionally, the conveying mechanism includes a support frame, conveying rollers, and a third rotating motor. The conveying rollers are spaced apart along the length of the support frame and rotatably connected to the support frame. The third rotating motor is mounted on the support frame, and the rotating shaft of the first rotating motor is connected to the conveying rollers.

[0018] By adopting the above technical solution, the conveying mechanism consists of a support frame, conveying rollers, and a third rotating motor, which realizes stable material transmission. Specifically, the support frame provides a stable mounting base for the conveying rollers, ensuring their smooth operation during operation. The conveying rollers are spaced apart along the length of the support frame, effectively supporting and conveying materials. The third rotating motor is connected to the conveying rollers, providing a power source for their rotation, ensuring that materials can move forward automatically and continuously, thus improving production efficiency.

[0019] Optionally, the longitudinal cutting mechanism includes a first longitudinal cutting roller, a second longitudinal cutting roller, a driving gear, and a driven gear. The first and second longitudinal cutting rollers are spaced apart and rotatably connected to the support frame. Both the first and second longitudinal cutting rollers are provided with cutting blades. The driving gear is coaxially connected to the first longitudinal cutting roller, and the driven gear is coaxially connected to the second longitudinal cutting roller. The driving gear and the driven gear mesh. A synchronous pulley is coaxially connected to the first longitudinal cutting roller, and a synchronous pulley is also coaxially connected to the third rotating motor. A synchronous belt is wound around the two synchronous pulleys.

[0020] By adopting the above technical solution, the first and second longitudinal cutting rollers are arranged at intervals and each is equipped with a cutting blade, which can achieve precise longitudinal cutting of materials; the meshing transmission of the driving gear and the driven gear makes the rotation of the first and second longitudinal cutting rollers coordinated and consistent, ensuring the stability of the cutting process; the use of the synchronous pulley and the synchronous belt effectively transmits the power of the third rotating motor to the first longitudinal cutting roller, realizing efficient power transmission and precise control of the cutting action.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By coordinating the conveying mechanism, the transverse cutting mechanism, and the longitudinal cutting mechanism, the transverse and longitudinal cutting of the sponge can be achieved simultaneously, taking into account both cutting efficiency and dimensional accuracy. This significantly improves cutting accuracy and product consistency, and addresses the problem that when the sponge needs to be cut into blocks in both transverse and longitudinal directions, it cannot be achieved by using only a fixed cutter, which would increase the number of subsequent processing steps.

[0023] 2. The rotary cutter and the rotating rod are connected by a threaded connection for easy detachment and installation, which makes it easy to replace or adjust the position of the rotary cutter according to actual needs. It can adapt to the cutting needs of different widths of sponge and has strong applicability.

[0024] 3. The matching arrangement of the pressure plate, movable rod, crossbar, pressure roller and buffer spring enables the pressure roller to move stably along the vertical direction. At the same time, the buffer spring provides appropriate downward pressure to the pressure roller, ensuring close contact between the pressure roller and the material surface, preventing material deviation during the cutting process and improving cutting quality.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a sponge cutting device. (Refer to...) Figure 1 The sponge cutting device includes a conveying mechanism 1, a transverse cutting mechanism 2, and a longitudinal cutting mechanism 3. The conveying mechanism 1 is used to transport materials. The transverse cutting mechanism 2 is located in the middle of the conveying mechanism 1 and is used to cut along the length of the conveying mechanism 1. The longitudinal cutting mechanism 3 is located at the end of the conveying mechanism 1 and is used to cut along the width of the conveying mechanism 1.

[0032] In use, the material is continuously conveyed along the length of the conveying mechanism 1. The material is then cut laterally by the transverse cutting mechanism 2, and then cut into strips of sponge. The material is then cut into blocks by the longitudinal cutting mechanism 3. Through the coordinated work of the three, the cutting accuracy and efficiency are improved. This solves the problem that when the sponge needs to be cut into blocks in both the transverse and longitudinal directions, it is impossible to achieve this with just a fixed cutter, which would increase the number of subsequent processing steps.

[0033] For example, the conveying mechanism 1 includes a support frame 11, conveying rollers 12, and a third rotary motor 13. The conveying rollers 12 are spaced apart along the length of the support frame 11 and rotatably connected to the support frame 11. The third rotary motor 13 is mounted on the support frame 11, and the rotation shaft of the third rotary motor 13 is connected to the conveying rollers 12 at the conveying end of the conveying mechanism 1. The number of conveying rollers 12 can be adjusted according to actual needs, for example, it can be set to three or four to ensure the stability of the material during the conveying process. In this application, four rollers are used.

[0034] Specifically, refer to Figure 1-2The transverse cutting mechanism 2 includes a mounting frame 21, a rotating rod 22, a rotating cutter 23, and a first rotating motor 24. The mounting frame 21 is fixed to the middle of the support frame 11 along its width direction. The mounting frame 21, as a support structure, includes two vertical plates 211 and a horizontal plate 212 connected to the top of the vertical plates 211. The rotating rod 22 is disposed on the two vertical plates 211 along the width direction of the conveying mechanism 1, and is rotatably connected to the two vertical plates 211 around its own axis via bearings. The rotating cutter 23 is spaced apart on the rotating rod 22. To ensure the stability of the rotating cutter 23, a threaded connection can be used to fix it. Specifically, the rotating rod 22 has external threads on its peripheral wall, and the rotating cutter 23 has internal threaded holes along its own axis. The rotating cutter 23 is threadedly connected to the external threads of the rotating rod 22 through the internal threaded holes. Fastening nuts 25, threaded onto the rotating rod 22, are provided on both sides of the rotating cutter 23. The first rotary motor 24 is mounted on the vertical plate 211 of the mounting bracket 21, and the rotating shaft of the first rotary motor 24 is connected to the rotating rod 22. The first rotary motor 24 drives the rotating rod 22 to rotate, thereby driving the rotary cutter 23 to rotate and complete the transverse cutting action.

[0035] To further improve cutting accuracy, a pressure plate 4 is slidably connected to the mounting frame 21 along its vertical direction. The mounting frame 21 is equipped with an adjustment component for adjusting the height of the pressure plate 4. Specifically, grooves 213 are formed on the side walls of the two vertical plates 211. The two ends of the pressure plate 4 are slidably engaged in the grooves 213. A sliding through groove 41 is formed vertically on the top of the pressure plate 4, extending along the width of the support frame 11. A movable rod 42 is inserted vertically into the sliding through groove 41. A cross frame 43 is welded and fixed to the bottom of the movable rod 42 along the length of the support frame 11. Four pressure rollers 44 are rotatably connected to the bottom of the cross frame 43, and the positions of the four pressure rollers 44 correspond one-to-one with the positions of the conveyor rollers 12. A buffer spring 45 is sleeved on the movable rod 42. One end of the buffer spring 45 is connected to the cross frame 43, and the other end of the buffer spring 45 is connected to the pressure plate 4.

[0036] By adjusting the height of the mounting bracket 21, the pressure roller 44 can be pressed firmly against the material, ensuring the material remains stable and does not lift during cutting, thus improving cutting stability and quality. The additional buffer spring 45 makes the pressure roller 44 more elastic in its application to the material, providing appropriate downward pressure and allowing it to automatically adjust its position according to the material thickness. This ensures uniform pressure and close contact between the pressure roller 44 and the material surface, further improving cutting quality.

[0037] In addition, a ratchet 46 is coaxially connected to the pressure roller 44, and a pawl 47 is rotatably connected to the crossbar 43. The pawl 47 engages with the ratchet teeth of the ratchet 46 to prevent the pressure roller 44 from rotating in the opposite direction when subjected to force, thereby reducing the disturbance effect on the material when the rotating cutter 23 cuts the material, thus ensuring the stable pressing effect of the pressure roller 44 on the sponge and improving the material stability during the cutting process.

[0038] Specifically, the adjustment assembly includes a second rotary motor 5 and a lead screw 6. The second rotary motor 5 is vertically mounted on the mounting frame 21, and the lead screw 6 is connected to the rotating shaft of the second rotary motor 5. The lead screw 6 passes through the pressure plate 4 and is threadedly connected to the pressure plate 4. By controlling the forward and reverse rotation of the second rotary motor 5, the rotation direction of the lead screw 6 can be adjusted, thereby driving the pressure plate 4 to move up and down, achieving precise adjustment of the height of the pressure plate 4. This design not only improves the convenience of adjustment but also ensures precise control of the position of the pressure plate 4, thus adapting to the processing needs of materials of different thicknesses and improving the versatility and stability of the device.

[0039] For example, refer to Figure 1 and Figure 3 The longitudinal cutting mechanism 3 includes a first longitudinal cutting roller 31, a second longitudinal cutting roller 32, a driving gear 33, and a driven gear 34. The first and second longitudinal cutting rollers 31 and 32 are spaced apart vertically and rotatably connected to the support frame 11. Each of the first and second longitudinal cutting rollers 31 and 32 has a groove 35 along its length on its peripheral wall. The width of the groove opening is smaller than the width of the groove bottom. Cutting blades 36 are fitted into the grooves 35 on the first and second longitudinal cutting rollers 31 and 32, and the cutting blades 36 on the first and second longitudinal cutting rollers 31 and 32 can rotate to abut against each other. The driving gear 33 is coaxially connected to the first longitudinal cutting roller 31, and the driven gear 34 is coaxially connected to the second longitudinal cutting roller 32. The driving gear 33 and the driven gear 34 mesh. A synchronous pulley 37 is coaxially connected to the first longitudinal cutting roller 31, and a synchronous pulley 37 is also coaxially connected to the third rotating motor 13. A synchronous belt 38 is wound around the two synchronous pulleys 37.

[0040] When the third rotary motor 13 drives the conveyor roller 12 in the conveying mechanism 1 to rotate, it also drives the first longitudinal cutting roller 31 to rotate synchronously through the synchronous belt 38. The first longitudinal cutting roller 31 drives the second longitudinal cutting roller 32 to rotate in the opposite direction through gear transmission. When the cutting blades 36 on the first and second longitudinal cutting rollers 31 rotate to contact, longitudinal cutting of the material can be achieved. The meshing transmission between the driving gear 33 and the driven gear 34 ensures that the rotation of the first and second longitudinal cutting rollers 31 and 32 is coordinated and consistent, ensuring the stability of the cutting process. The combined use of the synchronous pulley 37 and the synchronous belt 38 effectively transmits the power of the third rotary motor 13 to the first longitudinal cutting roller 31, which not only achieves efficient power transmission and precise control of the cutting action, but also eliminates the need for an additional power source, saving manufacturing costs.

[0041] The implementation principle of the sponge cutting device in this embodiment is as follows: During use, the third rotary motor 13 is started to drive the conveyor roller 12 to rotate, thereby transporting the sponge. When the material is transferred to the bottom of the mounting frame 21, the second rotary motor 5 is started to drive the lead screw 6 to rotate, thereby driving the pressure plate 4 to move down. Under the action of the buffer spring 45, the pressure roller 44 under the cross frame 43 presses against the upper surface of the material to fix the material and prevent it from moving during the cutting process, thus improving the cutting quality. Then, the first rotary motor 24 is started to drive the rotating cutter 23 on the rotating rod 22 to rotate at high speed, thereby cutting the passing sponge laterally. When the material that has been laterally cut passes through the gap between the first longitudinal cutting roller 31 and the second longitudinal cutting roller 32, the first longitudinal cutting roller 31 and the second longitudinal cutting roller 32 will rotate in opposite directions under the joint transmission of the synchronous pulley 37, the synchronous belt 38, the driving gear 33 and the driven gear 34, thereby causing the upper and lower cutting blades 36 to cut the material longitudinally. It improves upon the problem that when sponges need to be cut into pieces in both horizontal and vertical directions, it is impossible to achieve this using only a fixed cutter, which would increase the number of subsequent processing steps.

[0042] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
