Description

Technical Field

[0001] The utility model relates to the field of plastic foam production, and particularly relates to a cutting device for plastic foam production with high precision. Background Technique

[0002] Foamed plastics are polymer materials with plastics as the basic component and containing a large number of air bubbles. Therefore, they can also be said to be composite plastics filled with gas. Compared with pure plastics, it has many excellent properties, such as light weight, high specific strength, can absorb impact loads, good heat insulation and sound insulation performance, etc. Thus, it has been widely used in the fields of industry, agriculture, construction, transportation, etc. Since the advent of foamed plastics, its uses have become increasingly extensive and the varieties have been continuously enriched. Among them, the more common traditional foamed plastics mainly include varieties such as polyurethane (PUR), polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), phenolic resin (PF), etc.

[0003] The current cutting device for plastic foam production, as described in the patent with publication number CN208962177U, includes a workbench, a resistor, a heating wire, a bracket. A chute is arranged along the width direction at the front end of the workbench surface. A scale line is arranged along the length direction of the chute on one side of the chute, and a number of evenly spaced threaded holes are arranged along the length direction of the chute on the other side of the chute; it also includes two positioners. The positioner includes a positioning plate A, a positioning plate B, a connecting plate, and a slider. One side edge of the positioning plate A is perpendicularly connected to one side edge of the positioning plate B to form an L shape. The positioning plate A and the positioning plate B are vertically arranged relative to the workbench surface and the positioning plate A is located on the side where the foam board feeding direction is located; the other side edge of the positioning plate B is perpendicularly connected to one side edge of the connecting plate to form an L shape.

[0004] Regarding the above related technology, the inventor believes that the resistor is arranged on the bracket and can move up and down relative to the bracket, and both ends of the heating wire are connected to the resistor. Since the length of the heating wire between the two resistors is fixed, in order to ensure the cutting effect, the resistance wire needs to be kept in a tensioned state, resulting in the inability to adjust the resistance wire to an inclined state, and thus it is difficult to cut the plastic foam at multiple angles, and further resulting in poor applicability of the entire cutting device.

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

[0025] Please refer to Figures 1-4, A high-precision cutting device for plastic foam production, including an adjustment mechanism 1. The adjustment mechanism 1 includes a cutting table 101. Transverse lead screws 103 are rotatably connected to both sides of the cutting table 101. Moving frames 104 are threadedly connected to the outer sides of the two groups of transverse lead screws 103. The transverse lead screws 103 are arranged to drive the moving frames 104 to move when rotating. On one side of the cutting table 101, first stepping motors 102 are symmetrically and fixedly connected. The output ends of the two groups of first stepping motors 102 are respectively fixedly connected to the two groups of transverse lead screws 103. The first stepping motors 102 are arranged to drive the transverse lead screws 103 to rotate when starting to work. Guide rods 105 slidably penetrate through the interiors of the two groups of moving frames 104. The two groups of guide rods 105 are both fixedly connected to the cutting table 101. The guide rods 105 are arranged to guide the movement of the moving frames 104.

[0026] Longitudinal lead screws 107 are rotatably connected to the interiors of the two groups of moving frames 104. Second stepping motors 106 are fixedly connected to the tops of the two groups of moving frames 104. The output ends of the two groups of second stepping motors 106 are respectively fixedly connected to the two groups of longitudinal lead screws 107. The second stepping motors 106 are arranged to drive the corresponding longitudinal lead screws 107 to rotate when starting to work. Cutting mechanism 2. The cutting mechanism 2 includes moving plates 201 threadedly connected to the outer sides of the two groups of longitudinal lead screws 107 respectively. The longitudinal lead screws 107 can drive the moving plates 201 to move up and down when rotating. Guide rails 108 are fixedly connected to the inner walls of the two groups of moving frames 104. The two groups of guide rails 108 are respectively slidably connected to the two groups of moving plates 201. The guide rails 108 are arranged to guide the up and down movement of the moving plates 201.

[0027] Hydraulic rods 212 are fixedly connected to the opposite sides of the two groups of moving plates 201. The output ends of the two groups of hydraulic rods 212 are both fixedly connected to traction blocks 208. The hydraulic rods 212 are arranged to drive the traction blocks 208 to move up and down when starting to work. An electric heating wire 207 is fixedly connected between the two groups of traction blocks 208. The electric heating wire 207 is arranged to generate heat when powered on, so that the plastic foam can be melted and cut when contacting the electric heating wire 207. At the same time, when the traction blocks 208 move up and down, the tension of the electric heating wire 207 can be adjusted, so as to adapt to adjusting the electric heating wire 207 to different inclination angles, and then meet the high-precision cutting of the plastic foam at multiple angles. Fixed plates 205 are fixedly connected to the tops of the two groups of moving plates 201. Reinforcing rib plates 209 are symmetrically and fixedly connected to the opposite sides of the two groups of fixed plates 205. The two groups of reinforcing rib plates 209 are respectively fixedly connected to the two groups of moving plates 201. The reinforcing rib plates 209 can further connect and fix the fixed plates 205 and the moving plates 201, so as to improve the connection stability between the fixed plates 205 and the moving plates 201.

[0028] Inside both groups of fixed plates 205, there are through-fixed material scraping rings 206. The heating wire 207 passes through both groups of material scraping rings 206. The setting of the material scraping ring 206 can scrape off the partially adhered plastic foam on the surface of the heating wire 207 when the traction block 208 pulls the heating wire 207 to move, so as to realize the startup cleaning of the heating wire 207. A material dropping groove 210 corresponding to the fixed plate 205 is provided on one side of the moving plate 201. The setting of the material dropping groove 210 facilitates the dropping of the plastic foam scraped off by the material scraping ring 206. At the bottom of both groups of material dropping grooves 210, there are material receiving boxes 211. The two groups of material receiving boxes 211 are respectively fixedly connected to the two groups of moving plates 201. The setting of the material receiving box 211 is used to catch the plastic foam dropping from the material dropping groove 210.

[0029] On both sides of the two groups of moving plates 201, there are symmetrically fixedly connected vertical plates 202. Between the two groups of vertical plates 202 on the same side, there are rotatably connected guide wheels 203. The heating wire 207 bypasses the outer sides of each group of guide wheels 203. The setting of the guide wheels 203 can play a guiding role for the heating wire 207. Symmetrically arranged limiting shafts 204 are provided at the top of the heating wire 207. The two groups of limiting shafts 204 are respectively fixedly connected to the vertical plates 202 on both sides. The setting of the limiting shafts 204 can play a limiting role for the heating wire 207 to reduce the probability of the heating wire 207 deviating from the outer side of the guide wheel 203.

[0030] During use, place the plastic foam to be cut on the top of the cutting table 101, and then connect the heating wire 207 to the power supply so that the heating wire 207 can generate heat when it is energized and working. When the heating wire 207 contacts the plastic foam to be cut, it can cut the plastic foam. During the cutting process, the first stepping motors 102 on both sides can be started, so that the first stepping motors 102 can drive the transverse lead screw 103 to rotate when they start working. When the transverse lead screw 103 rotates, it can drive the corresponding moving frame 104 and moving plate 201 to move, so as to realize the adjustment of the transverse cutting position. When the moving frames 104 on both sides move out of sync, one side of the hydraulic rod 212 can be started, so that the hydraulic rod 212 can drive the traction block 208 to move upward when it starts working, thereby reducing the probability that the distance between the two guide wheels 203 increases due to the asynchronous movement of the two moving plates 201 following the two moving frames 104, and further reducing the probability that the heating wire 207 is broken. When the second stepping motor 106 starts working, it can drive the longitudinal lead screw 107 to rotate. When the longitudinal lead screw 107 rotates, it can drive the moving plate 201 to move up and down, thereby realizing the adjustment of the height of the heating wire 207. When the two moving plates 201 move up and down out of sync, one side of the hydraulic rod 212 can be started, so that the hydraulic rod 212 can drive the traction block 208 to move upward when it starts working, thereby reducing the probability that the distance between the two guide wheels 203 increases due to the asynchronous movement of the two moving plates 201 following the two moving frames 104, and further reducing the probability that the heating wire 207 is broken, so as to meet the inclined cutting of the plastic foam.
