Description

Technical Field

[0001] This utility model relates to the field of material processing equipment technology, and in particular to a foamed sponge disc flat cutting device. Background Technology

[0002] Currently, in the field of foamed sponge processing, with the continuous development of various industries, the demand for foamed sponge products is increasing day by day. Due to its softness and good elasticity, foamed sponge has been widely used in many industries such as furniture manufacturing, automotive interiors, and packaging materials. Efficient and precise foamed sponge processing technology can not only significantly improve product quality but also effectively reduce production costs, meeting the market's diverse product demands.

[0003] Most existing technologies use mechanical cutting to process sponges. Mechanical cutting uses a fixed cutting frame with blades. The sponge is placed in the cutting area, and the sponge is pushed or the cutting frame is moved to complete the cutting. During the pushing process, a stable force and speed need to be maintained to ensure that the sponge can be cut evenly by the blades.

[0004] Regarding the aforementioned technologies, in actual operation, the sponge may experience slight movement or deformation due to uneven weight distribution. During the cutting process, the cutting force of the blade on the sponge may further cause local deformation of the sponge, causing the originally set positioning point to shift, resulting in a difference between the cut sponge shape and the expected shape. Utility Model Content

[0005] To improve the stability of sponge cutting, this application provides a disc-shaped flat cutting device for foamed sponge.

[0006] This application provides a disc-shaped flat cutting device for foamed sponge, which adopts the following technical solution: A foamed sponge disc cutting device includes a frame, a disc at the upper end of the frame, a rotating component on one side of the disc for rotating the disc, a plurality of positioning components at the upper end of the disc evenly distributed along the circumference of the disc, the sponge being positioned within the positioning components during cutting, the positioning components positioning the sponge, a blade holder fixed at the upper end of the frame, the blade holder being vertically arranged, the disc being located at the lower end of the blade holder, a connecting plate at the upper end of the blade holder, a cutting plate on the side of the connecting plate near the disc, the cutting plate being detachably connected to the connecting plate, a plurality of cutting blades fixed on the side of the cutting plate away from the connecting plate, the plurality of cutting blades being arranged in a preset shape to cut the sponge.

[0007] By adopting the above technical solution, the rotating component drives the disc to rotate, causing the sponge to make circular motion on the disc. During the rotation of the disc, the cutting blade can continuously feed and cut the sponge, realizing continuous and uninterrupted production. Operators can pick up and put down the sponge from the same position, improving the convenience of the device. The cutting plate and the connecting plate are detachably connected. When it is necessary to switch to different cutting shapes, it is only necessary to quickly replace the cutting plate equipped with the corresponding arrangement of cutting blades. Several positioning components evenly distributed circumferentially at the upper end of the disc can position the sponge inside during cutting, so that the sponge maintains a relatively fixed position during the rotation of the disc, reducing the cutting deviation caused by the sponge shaking and displacement, and improving the stability of the device in cutting the sponge.

[0008] Optionally, the rotating component includes a motor, a gear ring, a first gear, and two second gears. The gear ring is fixed on the side of the disc away from the positioning component. The two second gears are located on one side of the gear ring and both second gears mesh with the gear ring. The first gear is located between the two second gears and meshes with the two second gears. The motor is fixed on the upper end of the frame, and the first gear is coaxially fixed with the motor output shaft.

[0009] By adopting the above technical solution, when the disc needs to rotate, the motor is started, and the motor stably transmits the rotational power to gear one. Gear one meshes with two gears two, thereby driving gear two to rotate. Gear two transmits power to the gear ring, which in turn drives the disc to rotate. When cutting the sponge, the rotation of the disc can ensure that the cutting blade has uniform contact with the sponge, thus improving the stability of the device.

[0010] Optionally, the positioning component includes several slide rods and several positioning plates. The positioning plates are located at the upper end of the disc and cooperate to form a cavity. The sponge is located inside the cavity. The slide rods correspond one-to-one with the positioning plates. The slide rods are located on the side of the positioning plates that are far apart from each other. The slide rods are threadedly connected to the corresponding positioning plates. Several grooves are opened on the surface of the disc. The slide rods are inserted into any groove and contact the inner wall of the groove.

[0011] By adopting the above technical solution, the cavity formed by the cooperation of several positioning plates provides a space for the sponge. During cutting, the sponge is confined within the cavity, reducing the probability of sponge movement. The slide rod is inserted into any groove on the surface of the disc. The operator can flexibly adjust the position of the positioning plate according to the actual size of the sponge. By changing the position of the groove into which the slide rod is inserted, the size of the cavity formed by the positioning plate can be changed, thus accommodating sponges of different sizes and improving the flexibility of the device.

[0012] Optionally, a number of connecting rods are fixed on the side of the cutting plate near the connecting plate. The connecting rods are evenly distributed along the surface of the connecting plate. A connecting groove corresponding to the connecting rod is opened on the side of the connecting plate near the cutting plate. The connecting rod is inserted into the corresponding connecting groove. A bolt is provided on one side of the connecting rod. A nut is provided at one end of the bolt. The bolt passes through the connecting rod and the connecting plate and is threadedly connected to the nut.

[0013] By adopting the above technical solution, a bolt is provided on one side of the connecting rod. The bolt passes through the connecting rod and the connecting plate and is threadedly connected to the nut. The cooperation of the bolt and nut provides a reliable mechanical fixation for the connection. This fixing method can effectively reduce the loosening of the cutting plate after high-speed cutting or long-term use, ensure the reliability of the connection between the cutting plate and the connecting plate, and facilitate the separation of the connecting plate and the cutting plate to replace cutting plates of different specifications, thereby improving the convenience of using the device.

[0014] Optionally, a number of telescopic rods are fixed on the side of the cutting plate near the disc. The telescopic rods are arranged vertically and are evenly distributed around the cutting plate. A pressing plate is fixed on the end of the moving rod away from the cutting plate. The telescopic rods are telescopic and can be extended and retracted to drive the pressing plate to move vertically.

[0015] By adopting the above technical solution, the telescopic rods are evenly distributed and vertically arranged around the cutting plate, providing a stable support frame for the pressing plate. During cutting, the pressing plate can press evenly onto the sponge surface under the action of telescopic extension, keeping the sponge flat and stable during the cutting process.

[0016] Optionally, the surface of the pressing plate has a positioning groove corresponding to the cutting blade. During the cutting process of the cutting blade on the pressing plate, the positioning groove limits the cutting blade.

[0017] By adopting the above technical solution, the positioning groove provides a precise cutting trajectory for the cutting blade. During the cutting process, the cutting blade is embedded in the positioning groove, and the sidewall of the positioning groove can restrict the movement direction of the cutting blade, allowing it to move only along a preset path. This reduces shaking and vibration during the cutting process, resulting in a smoother and flatter cut surface, reducing the generation of burrs, flash, and other defects, and improving the cutting quality of the sponge.

[0018] Optionally, a cylinder is fixedly installed at the upper end of the frame, and a connecting plate is fixedly connected to the output end of the cylinder. Two guide rods are fixedly installed inside the tool holder. The guide rods are arranged vertically, and the two guide rods pass through the connecting plate. The connecting plate is slidably connected to the guide rods along the length of the guide rods.

[0019] By adopting the above technical solution, the cylinder serves as the power source, controlling the vertical movement distance of the connecting plate. The guide rod provides precise guidance for the movement of the connecting plate, ensuring that the connecting plate can only move in a straight line along the vertical direction of the guide rod. When cutting the sponge, the cutting blade is controlled to accurately cut into the sponge to achieve the preset cutting depth, improving the ease of use of the device.

[0020] Optionally, a number of fixing rods are fixed at the lower end of the disc, and a sliding groove is opened on the surface of the frame. The fixing rods are detached from the sliding groove and are slidably connected to the frame along the sliding groove.

[0021] By adopting the above technical solution, when the disc rotates, the fixed rod slides in the groove of the frame, which can support and guide the disc, making the disc rotation more stable, reducing the shaking or deviation of the disc during rotation, and ensuring the cutting accuracy and stability of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Several positioning components evenly distributed circumferentially at the upper end of the disc can position the sponge inside during cutting, so that the sponge maintains a relatively fixed position during the rotation of the disc, reducing the cutting deviation caused by the sponge shaking and displacement, and improving the stability of the device for cutting the sponge. 2. The slide rod is inserted into any groove on the surface of the disc. The operator can flexibly adjust the position of the positioning plate according to the actual size of the sponge. By changing the position of the groove into which the slide rod is inserted, the size of the cavity formed by the positioning plate can be changed, thus making it suitable for sponges of different sizes and improving the flexibility of the device. 3. During the cutting process, the cutting blade is embedded in the positioning groove. The side wall of the positioning groove can restrict the movement direction of the cutting blade, so that it can only move along the preset path, making the cutting surface smoother and reducing the generation of defects such as burrs and flash, thus improving the cutting quality of the sponge.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a device for flat-cutting foamed sponge discs. Example

[0033] Reference Figure 1 and Figure 2 A disc-shaped flat cutting device for foamed sponge includes a frame 1, with a disc 11 at the upper end of the frame 1. The upper end of the disc 11 is provided with a plurality of positioning components, which are evenly distributed around the circumference of the disc 11. The positioning components include a plurality of sliding rods 112 and a plurality of positioning plates 111. The plurality of positioning plates 111 are located at the upper end of the disc 11 and cooperate to form a cavity. When processing the sponge, the worker places the sponge in the cavity. The sponge is confined in the cavity, which reduces the probability of accidental movement during subsequent sponge processing and improves the stability of the device.

[0034] Reference Figure 1 and Figure 2 The slide rod 112 corresponds one-to-one with the positioning plate 111. The slide rod 112 is located on the side of the positioning plate 111 that is far away from each other. The slide rod 112 is threadedly connected to the corresponding positioning plate 111. The surface of the disc 11 has several grooves 113. The slide rod 112 is inserted into any groove 113 and contacts the inner wall of the groove 113. The operator can rotate the slide rod 112 according to the actual size of the sponge, so that the slide rod 112 is separated from the current groove 113 and locked into different grooves 113, thereby adjusting the position of the positioning plate 111 and changing the size of the cavity formed by the positioning plate 111. This makes it suitable for sponges of different sizes and improves the flexibility of the device.

[0035] Reference Figure 3 and Figure 4The sponge is placed on the upper end of the disc 11. A motor 121 is fixed on the upper end of the frame 1. A gear 123 is provided on the lower end of the disc 11. The gear 123 is fixed coaxially with the output shaft of the motor 121. When processing the sponge, the motor 121 starts and drives the gear 123 to rotate. Two gears 124 are provided on the outside of the gear 123. Both gears 124 mesh with the gear 123. The rotation of the gear 123 drives the two gears 124 to rotate simultaneously. A gear ring 122 is fixed on the lower end of the disc 11. The gear ring 122 meshes with the two gears 124. The rotation of the gears 124 drives the gears to rotate. The rotation of the gear ring 122 realizes the rotation of the disc 11. The disc 11 moves the sponge to the processing position.

[0036] Reference Figure 1 Several fixing rods 114 are fixed at the lower end of the disc 11. A sliding groove 115 is provided on the surface of the frame 1. The fixing rods 114 are detached from the sliding groove 115 and are slidably connected to the frame 1 along the sliding groove 115. When the disc 11 rotates, the fixing rods 114 slide in the sliding groove 115 of the frame 1, which can support and guide the disc 11, making the rotation of the disc 11 more stable, reducing the shaking or deviation of the disc 11 during rotation, and ensuring the cutting accuracy and stability of the device.

[0037] Reference Figure 5 and Figure 6 A blade holder 13 is fixedly mounted on the upper end of the frame 1. The blade holder 13 is arranged vertically. A disc 11 is located at the lower end of the blade holder 13. A cylinder 131 is fixedly mounted on the upper end of the blade holder 13. A connecting plate 133 is provided on the upper end of the disc 11. The connecting plate 133 is fixedly connected to the output end of the cylinder 131. When the sponge rotates to the lower end of the blade holder 13, the cylinder 131 starts and drives the connecting plate 133 to descend. A cutting plate 1333 is provided on the lower end of the connecting plate 133. The cutting plate 1333 is detachably connected to the connecting plate 133. Several cutting blades 1334 are fixedly mounted on the side of the cutting plate 1333 away from the connecting plate 133. The descending of the connecting plate 133 drives the cutting plate 1333 to descend, so that the cutting blades 1334 cut the sponge into a preset shape.

[0038] Reference Figure 7A pressing plate 1335 is provided on the side of the cutting plate 1333 near the disc 11. Several telescopic rods 1336 are fixed between the pressing plate 1335 and the cutting plate 1333. The telescopic rods 1336 are arranged vertically and are evenly distributed around the cutting plate 1333. An elastic element 1337 is provided inside the telescopic rod 1336. The elastic element 1337 can be a spring. The telescopic rods 1336 are telescopically adjustable through the elastic element 1337. When cutting the sponge, the cutting plate 1333 descends, which drives the pressing plate 1335 to descend. The pressing plate 1335 first contacts the sponge and presses it. As the cutting plate 1333 continues to descend, the elastic element 1337 is compressed. The cutting blade 1334 descends and cuts the sponge, keeping the sponge flat and stable during the cutting process.

[0039] Reference Figure 7 The pressing plate 1335 has a positioning groove 1338 on its surface corresponding to the cutting blade 1334. The positioning groove 1338 provides a precise cutting trajectory for the cutting blade 1334. During the cutting process, the cutting blade 1334 is embedded in the positioning groove 1338. The side wall of the positioning groove 1338 can restrict the movement direction of the cutting blade 1334, allowing it to move only along a preset path. This reduces shaking and vibration during the cutting process, resulting in a smoother and flatter cut surface, reducing burrs, flash, and other defects, and improving the cutting quality of the sponge. After the sponge is cut, the disc 11 carries the cut sponge to the operator. The operator removes the cut sponge and places unprocessed sponges, allowing the operator to pick up and place sponges from the same position, improving the convenience of using the device.

[0040] Reference Figure 6 A plurality of connecting rods are fixedly provided on the side of the cutting plate 133 near the connecting plate 133. The connecting rods are evenly distributed along the surface of the connecting plate 133. A connecting groove corresponding to the connecting rod is opened on the side of the connecting plate 133 near the cutting plate 1333. The connecting rod is inserted into the corresponding connecting groove. A bolt 1331 is provided on one side of the connecting rod. A nut 1332 is provided at one end of the bolt 1331. The bolt 1331 passes through the connecting rod and the connecting plate 133 and is threadedly connected to the nut 1332. The cooperation of the bolt 1331 and the nut 1332 provides a reliable mechanical fixation for the connection. This fixing method can effectively reduce the loosening of the cutting plate 1333 after high-speed cutting or long-term use, and ensure the reliability of the connection between the cutting plate 1333 and the connecting plate 133.

[0041] Reference Figure 6Furthermore, when it is necessary to replace the cutting plate 1333 with one of different shapes or specifications to meet different cutting needs, the operator only needs to loosen the nut 1332, pull the bolt 1331 out of the connecting rod and the connecting plate 133, and then the cutting plate 1333 can be easily removed from the connecting plate 133. When installing a new cutting plate 1333, simply insert the connecting rod into the corresponding connecting groove, then insert the bolt 1331 and tighten the nut 1332. The entire disassembly and assembly process is quick and convenient, improving the ease of use of the device.

[0042] Reference Figure 5 Two guide rods 132 are fixed inside the knife holder 13. The guide rods 132 are set vertically and pass through the connecting plate 133. The connecting plate 133 is slidably connected to the guide rods 132 along the length of the guide rods 132. During the cutting of the sponge, the guide rods 132 provide precise guidance for the movement of the connecting plate 133, ensuring that the connecting plate 133 can only move in a straight line along the vertical direction of the guide rods 132, controlling the cutting blade 1334 to accurately cut into the sponge, achieve the preset cutting depth, and improve the accuracy of the device.

[0043] The implementation principle of the foamed sponge disc flat cutting device in this application embodiment is as follows: The operator places the sponge in the cavity formed by the positioning plate 111. The rotating component 12 drives the disc 11 to rotate. The rotation of the disc 11 drives the sponge to rotate to below the knife holder 13. The cylinder 131 drives the cutting plate 1333 and the pressing plate 1335 to descend. The pressing plate 1335 first contacts the sponge and presses it. The cutting plate 1333 continues to descend. At this time, the elastic component 1337 is compressed. The cutting blade 1334 descends and cuts the sponge, so that the sponge remains flat and stable during the cutting process.

[0044] The above are all preferred 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.
