Technical Field
[0001] This utility model relates to the field of sponge processing technology, specifically a high-precision sponge processing cutting device with a positioning mechanism. Background Technology
[0002] Sponge is a porous material with good water absorption. It can be used for cleaning items and cushioning products. There are many types of sponges used in industrial production, such as foamed cotton, molded cotton, rubber cotton, and memory foam. Among them, foamed cotton is widely used as filling for daily necessities such as pillows, mattresses, and sofas. It is mainly made by using polymer materials such as polyether and additives to react and foam. After foaming, the sponge needs to be transferred to cutting equipment for shape processing. However, existing cutting devices for sponge processing still have certain problems in use: For example, a cutting device for sponge processing, as described in application number CN202322614378.8, includes a fixed frame. Multiple sets of support legs are fixedly connected to the lower end of the fixed frame. A T-shaped groove is provided on the upper side of one side of the fixed frame. Two T-shaped sliders are slidably connected to the inner wall of the fixed frame inside the T-shaped groove. Two sets of horizontal plates can be moved by a two-way screw, and the horizontal plates can move the vertical plate and the baffle. The other end of the baffle can play a limiting movement role with the cooperation of the T-shaped groove and the T-shaped slider, so that the baffle can play a limiting clamping role on the sponge. The conveying mechanism can play a conveying role on the sponge. Thus, with the cooperation of the conveying mechanism and the cutting mechanism, the sponge can be cut. Multiple sets of auxiliary rollers set inside the baffle can assist the movement of the sponge when the conveying mechanism plays a conveying role on the sponge, so as to better cooperate with the cutting mechanism to cut the sponge. Traditional sponge cutting devices lack an effective positioning structure during the cutting process, which makes the sponge prone to displacement during cutting, making it difficult to guarantee cutting accuracy. The dimensional error of the sponge product at the cut point is relatively large, affecting the product quality. Moreover, due to the elasticity of the sponge itself, the force of the cutting blade during the cutting process will cause the sponge to deform, resulting in the cutting position shift and further reducing the cutting accuracy.
[0003] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.
[0004] To address the aforementioned issues, an innovative design was implemented based on the existing single-axis vacuum dough mixer. Utility Model Content
[0005] The purpose of this utility model is to provide a high-precision sponge processing cutting device with a positioning mechanism, so as to solve the problems mentioned in the background art. In the process of sponge cutting device, there is no effective positioning structure, which makes the sponge easy to shift during cutting, making it difficult to guarantee cutting accuracy. The size error of the sponge product at the cut point is large, which affects the quality of the product. Moreover, since the sponge itself is elastic, the force of the cutting blade will cause the sponge to deform during the cutting process, resulting in the cutting position shift and further reducing the cutting accuracy.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-precision sponge processing cutting device with a positioning mechanism includes a base frame and a worktable. The worktable is welded to the upper end of the base frame, and fixed plates are welded to both sides of the worktable. A positioning column is fixed to the side of the fixed plate near the worktable. Four sets of positioning grooves are formed on the outer surface of the positioning column. A positioning sleeve is slidably connected to the outer surface of the positioning column. A positioning block is fixed to the inner side of the positioning sleeve near the fixed plate. A positioning plate is fixed to the outer end of the positioning sleeve. A third sliding groove is formed on the upper surface of the worktable. A sliding rod that is slidably connected to the third sliding groove is fixed to the bottom of the positioning plate. A second limiting shaft passes through the middle of the sliding rod. A spring is provided on the outer surface of the second limiting shaft. A rubber pad is attached to the side of the positioning plate near the worktable.
[0007] Preferably, four sets of positioning plates are symmetrically arranged along the upper end of the worktable, and the two ends of the second limiting shaft are fixed to the inner sidewall of the third slide groove, and one end of the spring is fixedly connected to the inner wall of the third slide groove, and the other end is fixedly connected to one side of the slide rod.
[0008] Using the above technical solution, the positioning sleeve can slide along the positioning column and be fixed in multiple positions through the positioning groove, thereby flexibly adjusting the position of the positioning block according to the size of the sponge. With the sliding connection between the bottom slide rod of the positioning plate and the slide groove of the worktable, as well as the reset action of the spring, the positioning plate drives the positioning block to fit tightly against the sponge. The rubber pad pasted on the outside of the positioning plate can increase the friction and prevent the sponge from shifting during cutting, thus achieving precise positioning.
[0009] Preferably, the outer surface of the worktable is provided with a cutting groove, the outer side of the worktable is provided with a first sliding groove, a drive motor is installed at one end of the worktable, the output end of the drive motor is movably connected to a lead screw, and the outer surface of the lead screw is threadedly connected to a first slider that is in contact with and slidably connected to the first sliding groove.
[0010] Using the above technical solution, the drive motor rotates and drives the lead screw to rotate. Since the lead screw is threadedly connected to the first slider and the first slider slides in contact with the first groove of the worktable, the first slider can slide linearly in the first groove, so that the relevant components can be moved along the worktable through the first slider to achieve precise processing of the sponge.
[0011] Preferably, a second slide groove is provided on the other outer side of the worktable, a first limiting shaft is fixed in the middle of the second slide groove, and a second slider is slidably connected to the outer surface of the first limiting shaft.
[0012] By adopting the above technical solution, the first limiting shaft is fixed in the middle of the second slide groove, providing a limited sliding track for the second slider, so that it can only slide along the outer surface of the first limiting shaft in the second slide groove, which can ensure the stability and accuracy of the movement of the second slider and help improve the accuracy and reliability of the entire cutting device.
[0013] Preferably, the upper end faces of the first and second sliders are fixed with a mounting bracket, and a cutting motor is bolted to the top center of the mounting bracket, and a cutting blade is installed at the output end of the cutting motor.
[0014] Using the above technical solution, mounting brackets are connected to the first and second sliders to provide stable support for the cutting motor and cutting blade. After the cutting motor starts, it drives the cutting blade to operate and, in conjunction with the horizontal movement of the slider, achieves precise cutting of the sponge.
[0015] Preferably, an L-shaped plate is welded to the upper end face of the fixing plate, an electric push rod is installed on the bottom end face of the L-shaped plate, a pressure plate is fixed to the extended end of the electric push rod, and two sets of pressure plates are symmetrically arranged along the worktable, and the pressure plates are distributed on both sides of the cutting groove. Several anti-slip protrusions are fixed to the bottom of the pressure plate.
[0016] Using the above technical solution, two sets of electric push rods symmetrically arranged on both sides of the cutting groove are fixed to the fixed plate by L-shaped plates. After starting, the electric push rods extend and drive the pressure plate to descend, so that the anti-slip protrusions are in close contact with the sponge surface. The pressure plate and the anti-slip protrusions apply pressure to the sponge, increasing the friction and effectively suppressing the elastic deformation and displacement of the sponge during the cutting process, thus ensuring the cutting accuracy.
[0017] Preferably, the outer surface of the workbench is symmetrically provided with a plurality of adsorption holes, the inside of the workbench is provided with a vacuum chamber that communicates with the adsorption holes, a vacuum pump is installed in the middle of the base frame, and vacuum suction tubes are connected to both sides of the vacuum pump and are connected to the vacuum chamber.
[0018] Using the above technical solution, after the vacuum pump is started, air is drawn from the vacuum chamber through the vacuum suction tube. Since the vacuum chamber is connected to the adsorption holes on the surface of the worktable, a negative pressure is formed at the adsorption holes, which tightly adsorbs the sponge onto the surface of the worktable, effectively preventing the sponge from shifting due to elastic deformation or external force during the cutting process, thereby ensuring cutting accuracy.
[0019] Compared with the prior art, the beneficial effects of this utility model are: this high-precision sponge processing cutting device with a positioning mechanism, 1. The positioning sleeve can slide along the positioning post and be fixed in multiple positions through the positioning groove, so that the position of the positioning block can be flexibly adjusted according to the size of the sponge. With the sliding connection between the bottom slide rod of the positioning plate and the slide groove of the worktable, as well as the reset action of the spring, the positioning plate drives the positioning block to fit tightly against the sponge. The rubber pad pasted on the outside of the positioning plate can increase the friction and prevent the sponge from shifting during cutting, thus achieving precise positioning. 2. Two sets of electric push rods symmetrically arranged on both sides of the cutting groove are fixed to the fixed plate by L-shaped plates. After starting, the electric push rods extend and drive the pressure plate to descend, so that the anti-slip protrusions are in close contact with the sponge surface. The pressure plate and the anti-slip protrusions apply pressure to the sponge, increasing the friction and effectively suppressing the elastic deformation and displacement of the sponge during the cutting process, thus ensuring the cutting accuracy. 3. After the vacuum pump is started, air is drawn from the vacuum chamber through the vacuum suction tube. Since the vacuum chamber is connected to the adsorption holes on the surface of the worktable, a negative pressure is formed at the adsorption holes, which tightly adsorbs the sponge onto the surface of the worktable, effectively preventing the sponge from shifting due to elastic deformation or external force during the cutting process, thereby ensuring cutting accuracy. 4. The drive motor rotates and drives the lead screw to rotate. Since the lead screw is threadedly connected to the first slider and the first slider slides in contact with the first groove of the worktable, the first slider can slide linearly in the first groove so that the relevant components can be moved along the worktable through the first slider to achieve precise processing of the sponge. 5. The first limiting shaft is fixed in the middle of the second slide groove, providing a limited sliding track for the second slider, so that it can only slide along the outer surface of the first limiting shaft in the second slide groove. This ensures the stability and accuracy of the movement of the second slider and helps to improve the precision and reliability of the entire cutting device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1 Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: A high-precision sponge processing cutting device with a positioning mechanism includes a base frame 1 and a worktable 2. The worktable 2 is welded to the upper end of the base frame 1. Fixing plates 14 are welded to both sides of the worktable 2. A positioning post 15 is fixed to the side of the fixing plate 14 near the worktable 2. Four sets of positioning grooves 16 are formed on the outer surface of the positioning post 15. A positioning sleeve 17 is slidably connected to the outer surface of the positioning post 15. A positioning block 18 is fixed to the inner side of the positioning sleeve 17 near the fixing plate 14. A positioning plate 19 is fixed to the outer end of the positioning sleeve 17. A third sliding groove 20 is formed on the upper surface of the worktable 2. A sliding rod 21 that is slidably connected to the third sliding groove 20 is fixed to the bottom of the positioning plate 19. A second limiting shaft 22 passes through the middle of the sliding rod 21. A spring 23 is provided on the outer surface of the second limiting shaft 22. A rubber pad 24 is attached to the side of the positioning plate 19 near the worktable 2. The positioning plates 19 are symmetrically arranged in four sets along the upper end of the worktable 2, and the two ends of the second limiting shaft 22 are fixed to the inner side wall of the third slide groove 20. One end of the spring 23 is fixedly connected to the inner wall of the third slide groove 20, and the other end is fixedly connected to one side of the slide rod 21.
[0024] This high-precision sponge processing cutting device with a positioning mechanism has a worktable 2 welded to the upper end of the base frame 1, with fixed plates 14 on both sides. A positioning post 15 fixed to one side of the fixed plate 14 has four sets of positioning grooves 16 on its outer surface. A positioning sleeve 17, slidably connected to the outer surface of the positioning post 15, has a fixed positioning block 18 inside and a fixed positioning plate 19 at its outer end. Positioning is achieved by the sliding of the positioning sleeve 17 on the positioning post 15 and the positioning grooves 16. The position of the positioning plate 19 can be adjusted according to the sponge size. The bottom slide rod 21 of the positioning plate 19 is slidably connected to the third slide groove 20 of the worktable 2. The second limiting shaft 22 runs through the middle of the 1st section. One end of the spring 23 on the outer surface is fixed to the inner wall of the third slide groove 20, and the other end is fixed to one side of the slide rod 21. When the sponge is placed on the worktable 2, the positioning plate 19 is squeezed by the sponge. The slide rod 21 slides in the third slide groove 20 and compresses the spring 23. The rebound force of the spring 23 makes the positioning plate 19 fit tightly against the sponge. At the same time, the rubber pad 24 on the side of the positioning plate 19 close to the worktable 2 increases the friction to achieve accurate positioning of sponges of different sizes, prevent the sponge from shifting during the cutting process, ensure cutting accuracy, and improve product quality.
[0025] Example 2 Please see Figure 1 , Figure 2 This utility model provides a technical solution: The outer surface of the worktable 2 has a cutting groove 3, and the outer side of the worktable 2 has a first sliding groove 4. A drive motor 5 is installed at one end of the worktable 2, and a lead screw 6 is movably connected to the output end of the drive motor 5. A first slider 7, which is in close contact with and slidably connected to the outer surface of the lead screw 6, is threadedly connected to the outer surface of the lead screw 6. A second sliding groove 9 is installed on the other outer side of the worktable 2, and a first limiting shaft 10 is fixed in the middle of the second sliding groove 9. A second slider 11 is slidably connected to the outer surface of the first limiting shaft 10. A mounting bracket 8 is fixed to the upper end face of the first slider 7 and the second slider 11. A cutting motor 12 is bolted to the top center of the mounting bracket 8, and a cutting blade 13 is installed at the output end of the cutting motor 12.
[0026] This high-precision sponge processing cutting device with a positioning mechanism has a cutting groove 3 on the outer surface of the worktable 2, which provides a cutting path for the cutting blade 13. By starting the drive motor 5, the drive motor 5 drives the lead screw 6 to rotate. The lead screw 6 drives the first slider 7, which is threaded on its outer surface, to slide linearly along the first slide groove 4. At the same time, the second slider 11, which is in the second slide groove 9 on the other side of the worktable 2, slides stably along the outer surface of the first limit shaft 10. The first slider 7 and the second slider 11 are supported by a fixed mounting frame 8, which provides a stable motion foundation for the cutting motor 12 and the output cutting blade 13, which are bolted to the top center of the mounting frame 8. During operation, the mounting frame 8 drives the cutting motor 12 and the cutting blade 13 to move smoothly along the cutting groove 3. The cutting motor 12 drives the cutting blade 13 to move at high speed, realizing precise cutting of the sponge, ensuring cutting accuracy and stability, improving cutting quality, meeting the processing and cutting needs of different sponges, and achieving high-precision operation.
[0027] Example 3 Please see Figure 4 , Figure 5 This utility model provides a technical solution: An L-shaped plate 25 is welded to the upper surface of the fixed plate 14. An electric push rod 26 is installed on the bottom surface of the L-shaped plate 25. A pressure plate 27 is fixed to the extended end of the electric push rod 26. Two sets of pressure plates 27 are symmetrically arranged along the worktable 2, and the pressure plates 27 are distributed on both sides of the cutting groove 3. Several anti-slip protrusions 28 are fixed to the bottom of the pressure plate 27. Several adsorption holes 29 are symmetrically opened on the outer surface of the worktable 2. A vacuum chamber 30 communicating with the adsorption holes 29 is opened inside the worktable 2. A vacuum pump 31 is installed in the middle of the base frame 1. Vacuum suction pipes 32 are connected to both sides of the vacuum pump 31, and the vacuum suction pipes 32 are connected to the vacuum chamber 30.
[0028] This high-precision sponge processing cutting device with a positioning mechanism has an L-shaped plate 25 welded to the upper surface of the fixed plate 14, with an electric push rod 26 connected to the bottom. Two sets of pressure plates 27, fixed at their extended ends, are symmetrically arranged along the worktable 2 and distributed on both sides of the cutting groove 3. When the electric push rod 26 is activated and extended, the pressure plate 27 descends, and the anti-slip protrusion 28 at the bottom makes close contact with the sponge surface. This increases friction and suppresses the displacement and elastic deformation of the sponge during the cutting process. At the same time, the suction holes 29 symmetrically opened on the outer surface of the worktable 2 are connected to the internal vacuum chamber 30. The vacuum pump 31 installed in the middle of the base frame 1 is connected to the vacuum chamber 30 through the vacuum suction pipes 32 on both sides. When the vacuum pump 31 is activated, it extracts the air in the vacuum chamber 30, creating a negative pressure at the suction holes 29, which firmly adsorbs the sponge onto the surface of the worktable 2, effectively fixing the sponge and ensuring the stability of the sponge position during the cutting process. This significantly improves the cutting accuracy and prevents the cutting position from shifting due to the elasticity of the sponge itself during the cutting process, further enhancing the cutting precision.
[0029] Working principle: When performing sponge cutting operations, the sponge is first placed on the workbench 2. At this time, the positioning sleeves 17 on the outer surface of the positioning posts 15 on the fixed plates 14 on both sides of the workbench 2 can slide and adjust along the positioning grooves 16, causing the positioning blocks 18 and positioning plates 19 to adapt to the size of the sponge. The bottom slide rod 21 of the positioning plate 19 slides in the third slide groove 20 and compresses the spring 23. The rebound force of the spring 23, together with the rubber pad 24, makes the positioning plate 19 fit tightly against the sponge, achieving initial positioning. Subsequently, the electric push rod 26 at the bottom of the L-shaped plate 25 welded to the upper end of the fixed plate 14 extends, causing the pressure plate 27 to descend, and its bottom anti-slip protrusions 28 press the sponge tightly. Meanwhile, the vacuum pump 31 in the middle of the base frame 1 draws air from the vacuum chamber 30 through the vacuum suction tube 32, causing the suction holes 29 on the outer surface of the worktable 2 to generate negative pressure to adsorb the sponge. The double fixation ensures the stability of the sponge. During cutting, the drive motor 5 drives the lead screw 6 to rotate, causing the first slider 7 to slide in the first slide groove 4, and the second slider 11 to slide stably along the first limit axis 10 in the second slide groove 9. The mounting frame 8, which is supported by both, drives the cutting motor 12 and the cutting blade 13 to move along the cutting groove 3. The cutting motor 12 drives the cutting blade 13 to operate at high speed to complete the precise cutting of the sponge, effectively overcoming the influence of the sponge's elasticity and ensuring cutting accuracy.
