Technical Field

[0001] This utility model relates to the field of foam die-cutting technology, and in particular to a foam die-cutting device. Background Technology

[0002] Foam is a material made by foaming plastic particles. Foam has a series of characteristics such as high elasticity, light weight, flexible bending, ultra-thin volume, and reliable performance. In order to adapt to different usage environments, large pieces of foam need to be divided into appropriately sized units to adapt to different usage spaces.

[0003] A search revealed that patent document CN217621042U discloses a foam die-cutting forming device, which includes a main board, a die-cutting frame mounted in the middle of the main board, a heating wire rotatably mounted in the middle of the die-cutting frame, a winding wheel included in the die-cutting frame, the heating wire coiled around the outer side of the winding wheel at the rear, the die-cutting frame including symmetrical mounting seats, the heating wire slidably mounted between the mounting seats, a through-hole for cooperating with the heating wire in the middle of the main board, and guide frames mounted on the left and right sides of the main board.

[0004] During die-cutting, the heating wire is arranged in a ring and driven by a winding wheel to rotate and cut the foam. The heating wire can be energized and heated. Combined with the cyclic rotation and cutting, the foam cutting speed can be guaranteed to be fast. It can also be guided by a guide frame, which is divided into two parts. The guide frame can be aligned and guided smoothly, and the centering angle can be adjusted to ensure cutting stability. However, the above foam die-cutting forming device has difficulty controlling the die-cutting accuracy due to the lack of a fixing structure for the foam. Utility Model Content

[0007] It also includes a fixing mechanism for securing the foam;

[0008] The fixing mechanism includes an electric telescopic rod, which is slidably installed at the bottom of the top plate. A connecting plate is fixedly connected to the output end of the electric telescopic rod. A horizontal plate is fixedly connected to the bottom of the connecting plate. A cutter is slidably installed at the bottom of the horizontal plate. A third groove is provided on one side of the connecting plate. A pressure plate is slidably installed on the inner surface of the third groove. Two first springs are fixedly connected to the pressure plate and the inner wall of the third groove.

[0009] In one embodiment of the present invention, two conveying rollers are rotatably mounted on the inner surface of the bracket, and the two conveying rollers are driven by a conveyor belt. Rollers are rotatably mounted on the inner surface of the bracket.

[0010] In one embodiment of the present invention, two synchronous pulleys are rotatably mounted on the outer surface of the bracket. The two synchronous pulleys are driven by a synchronous belt. One of the synchronous pulleys is fixedly connected to a conveyor roller. A first motor is fixedly connected to one side of the synchronous pulley. The first motor is fixedly mounted on one side of the bracket.

[0011] In one embodiment of this utility model, a support plate is slidably installed at the bottom of the conveyor belt, the support plate is fixedly installed on the top of two reinforcing ribs, and a protective plate is fixedly installed on the top of the reinforcing ribs. The protective plate is on the same horizontal plane as the top of the conveyor belt.

[0012] In one embodiment of this utility model, a first groove and a second groove are provided at the bottom of the top plate. A second threaded rod is rotatably installed on the inner surface of the second groove, and a cleaning block is slidably installed on the inner surface of the second groove. The cleaning block is threadedly connected to the second threaded rod, and one end of the second threaded rod is fixedly connected to a conveyor roller.

[0013] In one embodiment of this utility model, a first threaded rod is rotatably mounted on the inner surface of the first groove, a second motor is fixedly connected to one end of the first threaded rod, the second motor is fixedly mounted on one side of the top plate, a slider is slidably mounted on the inner surface of the first groove, the slider is threadedly connected to the first threaded rod, and the electric telescopic rod is fixedly mounted on the bottom of the slider.

[0014] In one embodiment of this utility model, a fourth groove is provided at the bottom of the horizontal plate, a fourth motor is fixedly connected to one side of the horizontal plate, a rotating shaft is fixedly connected to the output shaft of the fourth motor, the rotating shaft is rotatably mounted on the inner surface of the fourth groove, a connecting block is fixedly connected to the outer surface of the rotating shaft, a fifth groove and two sliding grooves are provided on the outer surface of the connecting block, the cutter is slidably mounted on the inner surface of the fifth groove, a second spring is fixedly mounted on one side of the connecting block, a clamping plate is fixedly connected to one end of the second spring, and one side of the clamping plate is slidably mounted on the inner surface of the sliding groove and extends into the inner cavity of the fifth groove.

[0015] In one embodiment of this utility model, two limiting grooves are formed on the outer surface of the pressure plate, and two limiting blocks are fixedly installed at the bottom of the connecting plate, with the limiting blocks slidably installed on the inner surface of the limiting grooves.

[0016] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0017] The foam die-cutting and forming device of this utility model involves a first motor output shaft driving a conveyor roller to rotate. Both conveyor rollers rotate via a conveyor belt, and two synchronous pulleys rotate via a synchronous belt. The top synchronous pulley drives a roller to rotate, and the foam passes over the outer surface of the roller. The roller does not affect the conveying of the foam, but only ensures that the foam is evenly adhered to the surface of the conveyor belt. When cutting the foam, a second motor output shaft drives a first threaded rod to rotate. The first threaded rod drives a slider to slide on the inner surface of a first groove. Simultaneously, the slider moves a cutter to the position where the foam needs to be cut via an electric telescopic rod. The electric telescopic rod extends, causing the cutter to cut the foam.

[0018] The foam die-cutting and forming device of this utility model uses a fourth motor output shaft to drive a rotating shaft, which in turn drives a connecting block to rotate. The connecting block drives the cutter to rotate 90°. With the help of an electric telescopic rod, the cutter is positioned on the inner surface of the cleaning block. At this time, the output shaft drives the second threaded rod to rotate, which in turn drives the second threaded rod to control the sliding of the cleaning block to clean the surface of the cutter. During the descent of the cutter, under the action of two first springs, the bottom of the pressure plate is lower than the cutter. Therefore, the pressure plate will first contact the foam. After contact, the pressure plate squeezes the foam, and then the cutter contacts the foam to cut it. By using a limiting block to slide on the inner surface of the limiting groove, the bottom of the pressure plate can be prevented from being far lower than the cutter, which would affect the conveyor belt's transport of the foam.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1 to 5 As shown, a foam die-cutting forming device of this utility model includes a bracket 1, two reinforcing ribs 11 fixedly installed in the middle of the bracket 1, a top plate 12 fixedly installed on the top of the bracket 1, and a conveyor belt 21 rotatably installed on the inner surface of the bracket 1; it also includes a fixing mechanism for fixing the foam; the fixing mechanism includes an electric telescopic rod 1213, the electric telescopic rod 1213 is slidably installed on the bottom of the top plate 12, a connecting plate 3 is fixedly connected to the output end of the electric telescopic rod 1213, a horizontal plate 31 is fixedly connected to the bottom of the connecting plate 3, a cutter 33 is slidably installed on the bottom of the horizontal plate 31, a third groove 301 is opened on one side of the connecting plate 3, a pressure plate 32 is slidably installed on the inner surface of the third groove 301, and two first springs 302 are fixedly connected to the pressure plate 32 and the inner wall of the third groove 301.

[0028] Existing foam die-cutting equipment only cuts foam using heating wires, but it does not fix the foam during cutting, making it difficult to cut the foam accurately.

[0029] In use, the foam is first placed on top of the conveyor belt 21. As the conveyor belt 21 rotates, it moves the foam along with it. The electric telescopic rod 1213 slides at the bottom of the top plate 12, and the electric telescopic rod 1213 slides the cutter 33 to the position where the foam needs to be cut. Then, the output end of the electric telescopic rod 1213 extends. Under the action of the two first springs 302, the pressure plate 32 first contacts the foam and gradually presses it down. Then, the top of the pressure plate 32 slides on the inner surface of the third groove 301. Immediately afterwards, the cutter 33 contacts the foam and cuts it. After cutting, the foam continues to move with the conveyor belt 21. Finally, the die-cut foam slides off the conveyor belt 21 and is collected.

[0030] Furthermore, such as Figure 2 As shown, two conveying rollers 2 are rotatably mounted on the inner surface of the bracket 1, and the two conveying rollers 2 are driven by the conveyor belt 21. Rollers 231 are rotatably mounted on the inner surface of the bracket 1.

[0031] Two synchronous pulleys 23 are rotatably mounted on the outer surface of the bracket 1. The two synchronous pulleys 23 are driven by a synchronous belt 24. One of the synchronous pulleys 23 is fixedly connected to the conveyor roller 2. A first motor 22 is fixedly connected to one side of the synchronous pulley 23. The first motor 22 is fixedly mounted on one side of the bracket 1.

[0032] A support plate 25 is slidably installed at the bottom of the conveyor belt 21. The support plate 25 is fixedly installed on the top of two reinforcing ribs 11. A protective plate 26 is fixedly installed on the top of the reinforcing ribs 11. The protective plate 26 is on the same horizontal plane as the top of the conveyor belt 21.

[0033] In use, the first motor 22 drives one of the conveyor rollers 2 to rotate via its output shaft. Both conveyor rollers 2 then start to rotate via the conveyor belt 21. At the same time, the first motor 22 also drives the synchronous pulley 23 to rotate via the synchronous belt 24. Both synchronous pulleys 23 then start to rotate via the synchronous belt 24. The synchronous pulley 23 at the top drives the roller 231 to rotate. The roller 231 has a smooth surface and rotates in the opposite direction to the conveyor belt 21. This allows the roller 231 to apply a certain pressure to the foam without affecting the conveyor belt 21's transport of the foam.

[0034] In order to prevent the cutter 33 from damaging the conveyor belt 21 when cutting the foam, two protective plates 26 are used to prevent the cutter 33 from contacting the conveyor belt 21. In addition, since the foam needs to be supported when cutting the foam, the support plate 25 is placed at the bottom of the conveyor belt 21, which can indirectly provide support for the foam.

[0035] Furthermore, such as Figure 3As shown, the top plate 12 has a first groove 121 and a second groove 122 at its bottom. A second threaded rod 1221 is rotatably installed on the inner surface of the second groove 122. A cleaning block 1222 is slidably installed on the inner surface of the second groove 122. The cleaning block 1222 is threadedly connected to the second threaded rod 1221. One end of the second threaded rod 1221 is fixedly connected to 1223. The 1223 is fixedly installed on one side of the conveyor roller 2.

[0036] In use, the output shaft of this utility model drives the second threaded rod 1221 to rotate, and the second threaded rod 1221 drives the cleaning block 1222 to slide on the inner surface of the second groove 122. When in use, the cutter 33 rotates to the inner surface of the cleaning block 1222, and the cleaning block 1222 can remove the residual foam on the surface of the cutter 33.

[0037] Furthermore, such as Figure 3 As shown, a first threaded rod 1211 is rotatably mounted on the inner surface of the first groove 121. A second motor 1214 is fixedly connected to one end of the first threaded rod 1211. The second motor 1214 is fixedly mounted on one side of the top plate 12. A slider 1212 is slidably mounted on the inner surface of the first groove 121. The slider 1212 is threadedly connected to the first threaded rod 1211. The electric telescopic rod 1213 is fixedly mounted on the bottom of the slider 1212.

[0038] When this utility model is in use, if it is necessary to move the position of the cutter 33, the output shaft of the second motor 1214 drives the first threaded rod 1211 to rotate. The first threaded rod 1211 can drive the slider 1212 to slide on the inner surface of the first groove 121. The slider 1212 further drives the electric telescopic rod 1213 to slide, thereby realizing the adjustment of the position of the cutter 33.

[0039] Furthermore, such as Figure 4 As shown, a fourth groove 311 is provided at the bottom of the horizontal plate 31. A fourth motor 313 is fixedly connected to one side of the horizontal plate 31. A rotating shaft 312 is fixedly connected to the output shaft of the fourth motor 313. The rotating shaft 312 is rotatably mounted on the inner surface of the fourth groove 311. A connecting block 314 is fixedly connected to the outer surface of the rotating shaft 312. A fifth groove 3141 and two sliding grooves 3142 are provided on the outer surface of the connecting block 314. The cutter 33 is slidably mounted on the inner surface of the fifth groove 3141. A second spring 3144 is fixedly mounted on one side of the connecting block 314. A retaining plate 3143 is fixedly connected to one end of the second spring 3144. One side of the retaining plate 3143 is slidably mounted on the inner surface of the sliding groove 3142 and extends through the inner cavity of the fifth groove 3141.

[0040] When this utility model is in use, when it is necessary to clean the residual foam on the surface of the cutter 33, the output shaft of the fourth motor 313 drives the rotating shaft 312 to rotate, the rotating shaft 312 further drives the connecting block 314 to rotate, the connecting block 314 drives the cutter 33 to rotate 90° and, together with the electric telescopic rod 1213, the cutter 33 can be aligned with the inner surface of the cleaning block 1222, and then the cleaning block 1222 can sweep along the surface of the cutter 33 to clean the surface of the cutter 33;

[0041] When it is necessary to replace the cutter 33, pull the retaining plate 3143 so that one side of the retaining plate 3143 is pulled out from the inner surface of the slide groove 3142. At this time, the cutter 33 can be taken out. Then, put the top of the replacement cutter 33 into the inner surface of the fifth groove 3141, and then insert the retaining plate 3143 into the slide groove 3142 to complete the fixation of the cutter 33.

[0042] Furthermore, such as Figure 5 As shown, two limiting grooves 321 are formed on the outer surface of the pressure plate 32, and two limiting blocks 303 are fixedly installed at the bottom of the connecting plate 3. The limiting blocks 303 are slidably installed on the inner surface of the limiting grooves 321.

[0043] In use, by positioning the limiting block 303 on the inner surface of the limiting groove 321, the length of the pressure plate 32 extending beyond the cutter 33 can be limited, thus preventing the bottom of the pressure plate 32 from extending too far beyond the cutter 33, which would cause the pressure plate 32 to be in constant contact with the foam and affect the conveying of the foam.

[0044] Working principle: In use, the foam is first placed on the conveyor belt 21. Under the combined action of the rollers 231 and the conveyor belt 21, the foam moves along the conveyor belt 21. During use, the output shaft of the first motor 22 drives the conveyor rollers 2 to rotate. Both conveyor rollers 2 start to rotate after being driven by the conveyor belt 21. At the same time, the synchronous belt 24 drives the two synchronous pulleys 23 to rotate. The synchronous pulley 23 at the top drives the rollers 231 to rotate. The foam passes over the outer surface of the rollers 231. The rollers 231 do not affect the conveying of the foam, but only ensure that the foam is evenly attached to the surface of the conveyor belt 21. When cutting the foam, the output shaft of the second motor 1214 drives the first threaded rod 1211 to rotate. The first threaded rod 1211 drives the slider 1212 to slide on the inner surface of the first groove 121. At the same time, the slider 1212 moves the cutter 33 to the position where the foam needs to be cut through the electric telescopic rod 1213. The electric telescopic rod 1213 extends so that the cutter 33 cuts the foam.

[0045] When the cutter 33 needs to be replaced, the clamping plate 3143 is pulled out from the inner surface of the slide groove 3142, at which point the cutter 33 can be replaced. Then, when it is necessary to clean the foam residue from the surface of the cutter 33, the output shaft of the fourth motor 313 drives the rotating shaft 312 to rotate. The rotating shaft 312 further drives the connecting block 314 to rotate, and the connecting block 314 drives the cutter 33 to rotate 90°. This, combined with the electric telescopic rod 1213, positions the cutter 33 on the inner surface of the cleaning block 1222. At this time, the output shaft of 1223 drives the second threaded rod 1221... The rotation of the second threaded rod 1221 controls the sliding of the cleaning block 1222 to clean the surface of the cutter 33. During the descent of the cutter 33, under the action of the two first springs 302, the bottom of the pressure plate 32 is lower than the cutter 33. Therefore, the pressure plate 32 will first contact the foam. After contact, the pressure plate 32 squeezes the foam. Then the cutter 33 contacts the foam and cuts it. By sliding the limit block 303 on the inner surface of the limit groove 321, the bottom of the pressure plate 32 can be prevented from being far lower than the cutter 33, which would affect the conveyor belt 21's conveying of the foam.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
