Description

Technical Field

[0001] This utility model belongs to the field of compression molding technology, and in particular relates to a compression molding machine that produces uniform and fine foam cells in pearl cotton. Background Technology

[0002] Pearl cotton is a new type of environmentally friendly cushioning packaging material. Due to its excellent properties such as light weight, heat insulation, shock absorption, and corrosion resistance, it is widely used in the packaging protection of electronic products, precision instruments, furniture, and home appliances. Its performance directly depends on the uniformity and density of its internal cell structure. A uniform and dense cell structure means better cushioning performance, higher impact resistance, and more stable physical properties.

[0003] Chinese patent CN210633974U discloses a pearl cotton pressing and molding machine, including a base. Four legs are symmetrically fixedly installed at the bottom of the base. A material groove is carved at the top of the base, and pearl cotton is placed in the material groove. A second cylinder is embedded and fixedly installed in the base. A discharge port is carved on the side wall of the base away from the second cylinder. An inclined slide plate is fixedly installed on the outer side wall of the base. Two support plates are symmetrically fixedly installed at the top of the base. A top plate is fixedly installed at the end of the two support plates away from the base. A pressing mechanism is fixedly installed at the end of the top plate near the base and above the material groove.

[0004] As shown above, this device uses vertical pressing instead of traditional rolling pressing, which can press the entire pearl cotton at once. However, it can only press one piece of pearl cotton at a time. Its intermittent and batch operation mode results in low production efficiency and cannot meet the needs of modern industry for large-scale continuous production. At the same time, each pressing cycle is an independent process, which is easily affected by mold temperature fluctuations and material feeding deviations, making it difficult to guarantee the stability of the quality of large batches of products.

A frame is fixedly connected to the bottom of the lead screw. A limit shaft is fixedly connected to the outer wall of the frame for limiting the frame. The outer wall of the limit shaft is slidably connected to the inner wall of the support frame. An upper conveying assembly is provided on the frame. A cooling assembly is provided on the upper conveying assembly.

This compression molding machine, through the combination of worm gear, worm wheel and lead screw, realizes the adjustment of compression height, which can flexibly limit the foaming space of pearl cotton and meet the production needs of products with different thicknesses. At the same time, through the cooling component, the pearl cotton is cooled and shaped simultaneously when the first conveyor belt is running, and the collapse of the middle of the first conveyor belt is effectively prevented, ensuring the uniformity and stability of the product's cell structure.

[0013] 2. This compression molding machine utilizes the natural vibration generated during the operation of the second motor, which is transmitted to the first limiting plate through the connecting plate, causing it to vibrate slightly.

[0018] 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.

[0019] This utility model provides two technical solutions: Figures 1-4 The first embodiment of a compression molding machine for producing uniform and fine foam cells in pearl cotton is shown: The compression molding machine for producing uniform and fine foam cells in pearl cotton includes a base 1, a support frame 101 fixedly connected to the outer wall of the base 1, an adjustment mechanism 2 provided on the support frame 101 for adjusting the height of the pearl cotton foaming, a limit mechanism 3 provided below the support frame 101 for limiting the foaming on the left and right sides of the pearl cotton, and also includes; The adjusting mechanism 2 includes a fixed block 201 fixedly connected to the outer wall of the support frame 101. A worm gear 202 is rotatably connected to the inner wall of the fixed block 201. A worm wheel 203 meshes with the outer wall of the worm gear 202. A threaded barrel 204 is fixedly connected to the inner wall of the worm wheel 203. The outer wall of the threaded barrel 204 is rotatably connected to the outer wall of the support frame 101. A lead screw 205 is threadedly connected to the inner wall of the threaded barrel 204. The threaded barrel 204 is used to drive the lead screw 205 to move up and down. A frame 206 is fixedly connected to the bottom of the lead screw 205. A limiting shaft 207 is fixedly connected to the outer wall of the frame 206 for limiting the frame 206. The outer wall of the limiting shaft 207 is slidably connected to the inner wall of the support frame 101. An upper conveying assembly is provided on the frame 206. A cooling assembly is provided on the upper conveying assembly.

[0020] The upper conveying assembly includes a first motor 208 fixedly connected to the outer wall of the frame 206. The output shaft of the first motor 208 is fixedly connected to a first rotating shaft 209 via a coupling. The first rotating shaft 209 is connected to a first conveyor belt 210 via a pulley drive.

[0021] The cooling assembly includes a cooling device 211 fixedly connected to the outer wall of the frame 206. A cooling pipe 212 is fixedly connected to the outer wall of the cooling device 211 for circulating and transporting the coolant inside the cooling device 211 to cool and shape the foaming pearl cotton. A cooling plate 213 is fixedly connected to the inner wall of the frame 206 for cooling the pearl cotton and preventing the first conveyor belt 210 from collapsing. The cooling pipe 212 is located on the inner wall of the cooling plate 213, and the outer wall of the cooling plate 213 is in contact with the inner wall of the first conveyor belt 210.

[0022] When it is necessary to limit the height of the pearl cotton foam to make pearl cotton of different heights, firstly, manually rotate the worm gear 202 to drive the worm wheel 203 to rotate. As the worm wheel 203 rotates, it drives the threaded barrel 204 to rotate, which in turn causes the lead screw 205 to move. The movement of the lead screw 205 causes the frame 206 to move along with it. Due to the presence of the limiting shaft 207, the frame 206 is prevented from rotating along with the lead screw 205. After the height adjustment is completed, the first motor 208 is started via an external controller, driving the first rotating shaft 209 to rotate, thereby causing the first conveyor belt 210 to start moving. During the movement of the first conveyor belt 210, through... The external controller activates the cooling device 211, causing the coolant to circulate through the cooling pipe 212, thereby cooling the cooling plate 213 and shaping the foamed pearl cotton. At the same time, the cooling plate 213 also provides support to prevent the middle section of the first conveyor belt 210 from collapsing. This mechanism, through the combination of worm gear 202, worm wheel 203 and lead screw, realizes the adjustment of the pressing height, which can flexibly limit the foaming space of the pearl cotton and meet the production needs of products with different thicknesses. At the same time, through the cooling component, the pearl cotton is cooled and shaped simultaneously when the first conveyor belt 210 is running, and the collapse of the middle section of the first conveyor belt 210 is effectively prevented, ensuring the uniformity and stability of the product's cell structure.

[0023] Figures 5-6 The second embodiment is shown. The main difference between this embodiment and the first embodiment, which uses a compression molding machine to produce uniform and fine foam cells in pearl cotton, is that the limiting mechanism 3 includes a lower conveying assembly mounted on the base 1. A connecting plate 307 is fixedly connected to the lower conveying assembly. Two first limiting plates 308 are fixedly connected to the outer wall of the connecting plate 307. Second limiting plates 309 are slidably connected to the inner walls of the two first limiting plates 308 respectively. A fixed shaft 310 is fixedly connected to the outer wall of the second limiting plates 309. Second fixed plates 311 are fixedly connected to the outer walls of the two first limiting plates 308 respectively. A limiting rotating plate 312 is rotatably connected to the outer wall of the second fixed plate 311. The outer wall of the limiting rotating plate 312 is engaged with the inner wall of the fixed shaft 310.

[0024] The lower conveyor assembly includes a first fixed plate 301 fixedly connected to the base 1, a second motor 302 fixedly connected to the outer wall of the first fixed plate 301, a second rotating shaft 303 fixedly connected to the output shaft of the second motor 302 via a coupling, a second conveyor belt 304 connected to the second rotating shaft 303 via a pulley, and the outer wall of the second motor 302 fixedly connected to the inner wall of the connecting plate 307.

[0025] Based on the height adjusted by the adjusting mechanism 2, install different numbers of second limiting plates 309. First, slide the second limiting plates 309 into the grooves on the first limiting plate 308 to the bottom. Then, manually rotate the limiting rotating plate 312 so that the outer wall of the limiting rotating plate 312 contacts the outer wall of the fixed shaft 310, thereby limiting the second limiting plates 309. Then, start the second motor 302 through the external controller, which drives the second rotating shaft 303 to rotate. When the second rotating shaft 303 rotates, it will drive the second conveyor belt 304 to rotate. It should be noted that the speed of the second conveyor belt 304 should be consistent with that of the first conveyor belt 210 to avoid different speeds causing... The shearing force generated causes damage to the product. At the same time, the connecting plate 307 also has a support plate for supporting the second conveyor belt 304. During the operation of the second motor 302, the second motor 302 itself will vibrate. This vibration is transmitted to the first limiting plate 308 through the connecting plate 307, thereby causing the first limiting plate 308 to vibrate slightly. This mechanism can limit the foaming width of the pearl cotton. It also utilizes the natural vibration generated by the second motor 302 during operation, which is transmitted to the first limiting plate 308 through the connecting plate 307 to make it vibrate slightly. This can effectively prevent the foam material from sticking to the first limiting plate 308 and ensure the integrity of the product edge.
