Description

Technical Field

[0001] This utility model relates to the field of sponge production technology, specifically to a strip-cutting device for sponge production with a smooth cut. Background Technology

[0002] Sponge is a porous material with good water absorption and is widely used in the automotive industry, battery industry, cosmetics industry, bra and underwear manufacturing industry, and high-end furniture manufacturing industry. The strip cutting device in sponge production is one of the key pieces of equipment in the sponge manufacturing process. It is used to cut continuous sponge material into strips of a specific width or length for further processing or use.

[0003] According to the authorization announcement number CN222371688U, a slitting device for producing sponges with smooth cuts is disclosed. This technology discloses "a slitting device for producing sponges with smooth cuts, including a slitting device platform, an adjustable equidistant slitting component located on top of the slitting device platform, and a conveyor roller height adjustment component located inside the slitting device platform". It has the following technical effects: "Through the set conveyor roller height adjustment component, it can adapt to the conveying needs of sponges of different thicknesses, ensure the stability and reliability of the sponge slitting process, avoid sponge material from getting stuck between the rollers, causing conveyor belt blockage, reduce wear on sponge material and rollers, extend the service life of the equipment, eliminate the need for manual pushing of the sponge during slitting, and ensure high safety. At the same time, the conveyor roller can limit one end of the sponge to prevent the sponge from moving off-center during slitting, thus preventing the sponge from being cut unevenly".

[0004] The above solution achieves adjustable blade spacing through an adjustable equidistant cutting assembly. Since a bidirectional lead screw is used as the adjustment mechanism, the thread machining accuracy directly affects the accuracy of blade spacing adjustment. Mechanical wear during long-term use will further exacerbate this error, making it difficult to guarantee fine-tuning accuracy. In particular, when cutting narrower sponge strips, this cumulative error will be more obvious, directly affecting the cutting quality of the product. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a strip-cutting device for producing sponges with smooth cuts, comprising a base frame 1, on which a production device 2 is mounted and used for sponge production, the production device 2 comprising:

[0026] The main component 21 includes a frame 211 fixed to the top of the base frame 1;

[0027] The adjustment assembly 22 includes a base plate 221 fixed above the rear end of the frame 211. Several equally spaced slides 222 are slidably mounted on the rear end of the base plate 221. A cam 223 is rotatably mounted on the middle of the rear end of the slides 222. A balance bar 224 is fixed on the rear end of the frame 211. An actuator 225 is mounted on the lower end of the slides 222. A slide plate 226 is slidably mounted on the rear end of the base plate 221. Several symmetrically distributed guide grooves 227 are opened inside the slide plate 226, and the cam 223 is located in the corresponding guide groove 227. A drive component 228 is provided on the base plate 221 for driving the slide plate 226 to move.

[0028] In this embodiment, when the slide plate 226 moves up and down, several guide grooves 227 cooperate with several cams 223 to drive several slides 222 to move laterally at equal distances. At the same time, the slides 222 drive the cutter head 2252 to slide along the balance bar 224 through the shaft frame 2251, ensuring that the spacing of the cutter head 2252 is precise and controllable.

[0029] Specifically, the actuator 225 includes a shaft bracket 2251 fixed to the lower end of the slide 222, a cutter head 2252 rotatably mounted on the lower end of the shaft bracket 2251, and the cutter head 2252 is sleeved on the balance bar 224.

[0030] In this embodiment, the balance bar 224 ensures both the flexibility of the cutter head 2252 rotation and the stability of the cutting process.

[0031] Specifically, the main component 21 also includes a lower pressure roller 212 rotatably mounted inside the lower part of the frame 211, a shaft seat 213 longitudinally slidably mounted inside both ends of the frame 211, an upper pressure roller 214 rotatably mounted between the two shaft seats 213, a knob bolt 215 threadedly mounted on the upper part of both ends of the frame 211, and the lower end of the knob bolt 215 rotatably connected to the shaft seat 213, a 216 is provided on the frame 211 for driving the lower pressure roller 212 to rotate, an auxiliary component 217 is provided on the frame 211 for conveying the sponge, and a limit component 218 is provided on the frame 211 for limiting the sponge.

[0032] In this embodiment, the knob bolt 215 is rotated and the bearing seat 213 is used to drive the knob bolt 215 to move up and down, thereby adjusting the distance between the upper pressure roller 214 and the lower pressure roller 212 according to the thickness of the sponge.

[0033] Specifically, 216 includes a drive gear 2161 fixed to one end of the lower pressure roller 212, a driven sprocket 2162 fixed on the drive gear 2161, a driven gear 2163 fixed to one end of the upper pressure roller 214 and meshing with the drive gear 2161 for transmission, a reduction motor 2164 installed inside the base frame 1, a drive sprocket 2165 fixed to the output end of the reduction motor 2164, and a first chain 2166 installed between the drive sprocket 2165 and the driven sprocket 2162.

[0034] In this embodiment, the output end of the geared motor 2164 drives the drive sprocket 2165 to rotate in conjunction with the first chain 2166, which in turn drives the driven sprocket 2162 to rotate. The driven sprocket 2162 drives the lower pressure roller 212 to rotate through the drive gear 2161. At the same time, the drive gear 2161 also drives the upper pressure roller 214 to rotate through the driven gear 2163. Thus, the sponge is fed into the cutter head 2252 for cutting into strips through the lower pressure roller 212 and the upper pressure roller 214.

[0035] Specifically, the auxiliary component 217 includes a power roller 2171 rotatably mounted between the rear ends of the frame 211. One end of the power roller 2171 is fixed with a first transmission sprocket 2172, and one end of the lower pressure roller 212 is fixed with a second transmission sprocket 2173. A second chain 2174 is installed between the second transmission sprocket 2173 and the first transmission sprocket 2172.

[0036] In this embodiment, when the lower pressure roller 212 rotates, the second transmission sprocket 2173, in conjunction with the second chain 2174, drives the first transmission sprocket 2172 to rotate. The first transmission sprocket 2172 drives the power roller 2171 to rotate, feeding the sponge between the lower pressure roller 212 and the upper pressure roller 214.

[0037] Specifically, the limiting component 218 includes a mounting bracket 2181 fixed on both sides of the rear end of the frame 211. A cylinder 2182 is mounted on the outer wall of the mounting bracket 2181, and a limiting plate 2183 is fixed to the output end of the cylinder 2182.

[0038] In this embodiment, the limiting plate 2183 is moved by the output end of the cylinder 2182, thereby centering and limiting the incoming sponge.

[0039] Specifically, the drive component 228 includes a lead screw 2281 rotatably mounted on one end of the base plate 221, a guide sleeve 2282 threaded onto the lead screw 2281 and fixed on the slide plate 226, a driven pulley 2283 fixed at the upper end of the lead screw 2281, a servo motor 2284 mounted on one end of the base plate 221, a drive pulley 2285 fixed at the output end of the servo motor 2284, and a belt 2286 installed between the drive pulley 2285 and the driven pulley 2283.

[0040] In this embodiment, the output end of the servo motor 2284 drives the active pulley 2285 to rotate in conjunction with the belt 2286, which in turn drives the driven pulley 2283 to rotate. The driven pulley 2283 drives the slide plate 226 to move up and down through the lead screw 2281 and the guide sleeve 2282.

[0041] The working principle and usage process of this utility model are as follows: First, the output end of the servo motor 2284 drives the active pulley 2285 to rotate in conjunction with the belt 2286, which in turn drives the driven pulley 2283 to rotate. The driven pulley 2283 drives the slide plate 226 to move up and down through the lead screw 2281 and the guide sleeve 2282. When the slide plate 226 moves up and down, it drives several slides 222 to move laterally at equal distances through several guide grooves 227 and several cams 223. At the same time, the slides 222 drive the cutter head 2252 to slide along the balance bar 224 through the shaft frame 2251, ensuring that the spacing of the cutter head 2252 is precise and controllable.
