Technical Field

[0001] The utility model relates to the field of foam processing, in particular to a plastic foam cutting machine. Background Technique

[0002] Foamed plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. They have characteristics such as light weight, heat insulation, sound absorption, shock absorption, and their dielectric properties are superior to those of the matrix resin, and they are widely used. Almost all plastics can be made into foamed plastics, and foam molding has become an important field in plastic processing. During the production process of plastic foam, cutting equipment is required to cut it into the required shapes and sizes for easy use.

[0003] The current plastic foam cutting machine, as described in the patent of announcement CN214136406U, includes: a working frame, a cutting platform, a heating wire, a support frame, and a signal transmission box. The cutting platform is located above the working frame and is slidably connected to the upper surface of the working frame. There are two support frames, which are symmetrically distributed on the side surfaces of the working frame. The heating wire is buckled with the support frame, and the signal transmission box is connected to the inside of the support frame through a wire.

[0004] Regarding the above related technology, the inventor believes that after cutting, workers need to manually remove each piece of cut plastic foam from the cutting platform, resulting in a relatively high working intensity for the workers. Content of the Utility Model

[0005] The purpose of the utility model is to provide a plastic foam cutting machine to solve the problems raised in the above background technique.

[0024] The technical solutions of this patent will be further elaborated in detail below in combination with the specific embodiments.

[0025] Please refer toFigures 1-5 , a plastic foam slitter, including a slitting mechanism 1. The slitting mechanism 1 includes a connecting plate 102. Both ends of the connecting plate 102 are fixedly connected with support frames 101. The setting of the connecting plate 102 can connect and fix the two groups of support frames 101. A transverse lead screw 104 is rotatably connected to the opposite sides of the two groups of support frames 101. A moving beam 106 is threadedly connected to the outer sides of the two groups of transverse lead screws 104. The setting of the transverse lead screw 104 is used to drive the moving beam 106 to move when rotating. A first stepping motor 105 is fixedly connected to one side of each of the two groups of support frames 101. The output ends of the two groups of first stepping motors 105 are respectively fixedly connected with the two groups of transverse lead screws 104. The setting of the first stepping motor 105 is used to drive the transverse lead screw 104 to rotate when starting to work.

[0026] A longitudinal lead screw 109 is rotatably connected to the inside of each of the two groups of moving beams 106. A slider 108 is threadedly connected to the outer sides of the two groups of longitudinal lead screws 109. The setting of the longitudinal lead screw 109 is used to drive the slider 108 to move up and down when rotating. A second stepping motor 107 is fixedly connected to the top of each of the two groups of moving beams 106. The output ends of the two groups of second stepping motors 107 are respectively fixedly connected with the two groups of longitudinal lead screws 109. The setting of the second stepping motor 107 is used to drive the longitudinal lead screw 109 to rotate when starting to work. An electric heating wire 103 is fixedly connected between the two groups of sliders 108. The setting of the electric heating wire 103 is used to generate heat when powered on, so that the plastic foam can be cut when contacting the electric heating wire 103. A support mechanism 2, the support mechanism 2 includes a rotating plate 201 symmetrically and rotatably connected to the opposite sides of the two groups of support frames 101. The setting of the rotating plate 201 is used to provide support for the foam plastic to be cut when rotating to the horizontal.

[0027] Avoidance grooves 215 adapted to the connecting plate 102 are provided at the tops of the two groups of rotating plates 201. The connecting plate 102 is inserted into the interiors of the two groups of avoidance grooves 215. The setting of the avoidance grooves 215 can accommodate the connecting plate 102, so that the rotating plate 201 will not be blocked by the connecting plate 102 when rotating to the horizontal. A double-axis stepping motor 206 is fixedly connected to the bottom of each of the two groups of rotating plates 201. The output ends of the two groups of double-axis stepping motors 206 are both fixedly connected with adjusting screws 207, and the thread directions on the outer sides of the adjusting screws 207 on both sides are opposite. A moving block 208 is threadedly connected to the outer side of each adjusting screw 207, so that when the double-axis stepping motor 206 rotates, it can drive the adjusting screws 207 on both sides to rotate synchronously, thereby driving the moving blocks 208 on both sides to move relatively or away from each other.

[0028] A C-shaped clamp 210 is rotatably connected to the outside of each moving block 208. The C-shaped clamp 210 can move synchronously with the moving block 208, so that when the two moving blocks 208 move relative to each other, the C-shaped clamps 210 on both sides can be driven to move relative to each other, thereby clamping and fixing the foam plastic to be cut. Avoidance openings 209 corresponding to the C-shaped clamps 210 are symmetrically formed on both sides of the two rotating plates 201. The C-shaped clamps 210 penetrate through the avoidance openings 209. The avoidance openings 209 are provided to avoid the C-shaped clamps 210. Guide grooves 212 are formed on the inner walls of the avoidance openings 209 in each group. Guide rods 211 adapted to the guide grooves 212 are symmetrically and fixedly connected to the outside of each C-shaped clamp 210. The guide rods 211 can slide inside the guide grooves 212 as the C-shaped clamps 210 move, thereby restricting the rotation of the C-shaped clamps 210.

[0029] On one side of the inner wall of each avoidance opening 209, an opening groove 213 communicating with the guide grooves 212 in each group is formed. After the guide rod 211 slides into the opening groove 213, the limit on the guide rod 211 can be stopped, so that the guide rod 211 can rotate. Second gears 216 are symmetrically and fixedly connected to the outside of each C-shaped clamp 210. Second racks 214 corresponding to the second gears 216 are fixedly connected to the four corners of the bottom of the two rotating plates 201. When the second gears 216 move to mesh with the second racks 214 and continue to move, the second racks 214 can drive the second gears 216 and the C-shaped clamps 210 to rotate, so that the C-shaped clamps 210 can rotate to the horizontal position, thereby facilitating the placement of the plastic foam to be cut on the tops of the two rotating plates 201. A torsion spring 217 is fixedly connected between each second gear 216 and the moving block 208. The torsion spring 217 can use its elastic force to pull the second gear 216 to rotate, so that the C-shaped clamp 210 remains in the vertical state, thereby facilitating the alignment and meshing of the second rack 214 and the second gear 216.

[0030] Both ends of the two groups of rotating plates 201 are fixedly connected with first gears 202. The opposite sides of the first gears 202 on both sides are meshed with first racks 203, so that when the first racks 203 move up and down, they can drive the first gears 202 and the corresponding rotating plates 201 to rotate. A chute 111 is provided on the side of each first rack 203 close to the support frame 101. A sliding rail 110 adapted to each chute 111 is provided inside each chute 111. Each sliding rail 110 is fixedly connected with the support frame 101. The arrangement of the sliding rail 110 and the chute 111 can play a guiding role in the up and down movement of the first rack 203. A connecting beam 204 is fixedly connected between the two first racks 203 on the same side. The arrangement of the connecting beam 204 can connect the two first racks 203, so that the two first racks 203 can move up and down synchronously, and then drive the first gears 202 on both sides to rotate synchronously. A hydraulic rod 205 is fixedly penetrated through the interiors of the two connecting beams 204. The output ends of the two hydraulic rods 205 are fixedly connected with the rotating plate 201. The hydraulic rod 205 is provided to drive the connecting beam 204 to move up and down when starting to work.

[0031] During use, start the two-side dual-axis stepper motor 206, so that the dual-axis stepper motor 206 drives the corresponding two adjusting screws 207 to rotate, thereby driving the moving blocks 208 on both sides to move away from each other until the second gears 216 on both sides are engaged with the corresponding second racks 214, and then continue to move away from each other, so as to drive the second gears 216 and the C-shaped clamping plates 210 to rotate until each group of C-shaped clamping plates 210 rotates to the horizontal. Then, the plastic foam to be cut can be placed on the tops of the two rotating plates 201. Then, start the two groups of dual-axis stepper motors 206 again, so as to drive the moving blocks 208 and the C-shaped clamping plates 210 on both sides to move relatively, so that the second rack 214 drives the corresponding second gear 216 to rotate to the vertical state. Then, continue to move relatively under the drive of each moving block 208 until the C-shaped clamping plates 210 on both sides clamp and fix the foam plastic to be slit. Then, energize the heating wire 103, and start the second stepper motor 107 and the first stepper motor 105, so that when the second stepper motor 107 starts to work, it can drive the longitudinal lead screw 109 to rotate. When the longitudinal lead screw 109 rotates, it can drive the slider 108 and the heating wire 103 to move up and down, so that when the heating wire 103 contacts the plastic foam, the foam plastic is slit. At the same time, the first stepper motor 105 can also be started, so that the first stepper motor 105 can drive the transverse lead screw 104 to rotate. When the transverse lead screw 104 rotates, it can drive the moving beam 106 and the heating wire 103 to move, so as to realize the adjustment of the slitting position. After the plastic foam is slit, the hydraulic rod 205 can be started, so that the hydraulic rod 205 can drive the connecting beam 204 and the first rack 203 to move downward, thereby driving the first gear 202 and the rotating plate 201 to rotate, so that the cut foam plastic falls from between the two rotating plates 201, so that there is no need for workers to manually remove the slit plastic foam one by one.
