Technical Field

[0001] The utility model belongs to the technical field of plastic thermoforming production equipment, and particularly relates to a plastic thermoforming cutting machine. Background Art

[0002] A plastic thermoforming machine is also called a thermoplastic forming machine. Its working principle is as follows: using the vacuum suction generated by a vacuum pump to suck the heated and softened thermoplastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc. through a mold to form various-shaped vacuum covers, or attach them to the surfaces of various-shaped products. The plastic thermoforming process can be divided into thin-sheet thermoforming and thick-sheet thermoforming according to the thickness of the sheet.

[0003] In the existing plastic thermoforming cutting machine, when cutting the materials after plastic thermoforming, it is necessary to manually place the materials to be cut in the designated cutting area and then cut the materials. However, the manual operation speed is limited by the operator's operation speed and cannot reach the speed and efficiency of automated production, thus restricting the production capacity. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a plastic thermoforming cutting machine, which solves the problem that the manual operation speed is limited by the operator's operation speed and cannot reach the speed and efficiency of automated production, thus restricting the production capacity, by setting a conveying mechanism.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a plastic thermoforming cutting machine, including support legs, on which a conveying mechanism and a cutting mechanism are arranged;

[0007] The conveying mechanism includes a first rotating shaft rotatably connected between two support legs. The two first rotating shafts are arranged on the left and right sides of the two support legs. The front end of the first rotating shaft on the left rotates through the outer wall of the front support leg and extends to the outside. Circular rollers are fixedly connected to both of the two first rotating shafts, and a conveyor belt is sleeved on the two circular rollers.

[0008] Further, the cutting mechanism includes a cutting component, a first transmission component, and a second transmission component. The cutting component includes a U-shaped support frame fixedly connected to two support legs, and a threaded cylinder rotatably penetrates through the central axis of the U-shaped support frame.

[0009] Further, a reciprocating lead screw is threadedly connected to the inner wall of the threaded cylinder, and trapezoidal grooves are respectively formed on the front and back inner walls of the U-shaped support frame.

[0010] Further, a lifting plate is slidably connected to the inner walls of the two trapezoidal grooves. The top of the lifting plate is rotatably connected to the reciprocating lead screw, and the bottom of the lifting plate is fixedly connected to a dividing blade.

[0011] Further, a rotating groove is provided at the central axis of the U-shaped support frame. A clamping ring is fixedly connected to the outer wall of the threaded cylinder, and the outer wall of the clamping ring extends into the rotating groove and is rotatably connected to the rotating groove.

[0012] Further, the first transmission assembly includes a second rotating shaft rotatably connected to the front surface of the front support leg. A gear is fixedly connected to the outer wall of the conveying mechanism. A semi-gear is fixedly connected to the outer wall of the second rotating shaft. The gear meshes with the semi-gear. A motor is fixedly connected to the front side of the second rotating shaft. A motor sleeve is fixedly connected to the outer wall of the motor, and the rear side of the motor sleeve is fixedly connected to the front support leg.

[0013] Further, two support plates are fixedly connected to the top of the U-shaped support frame. A third rotating shaft is rotatably connected between the two support plates. The front side and the rear side of the third rotating shaft respectively penetrate through the outer walls of the two support plates and extend to the outside. Trapezoidal gears are fixedly connected to both the threaded cylinder and the third rotating shaft, and the two trapezoidal gears mesh with each other.

[0014] Further, the second transmission assembly includes pulley wheels fixedly connected to the second rotating shaft and the third rotating shaft respectively, and a belt is sleeved on the two pulley wheels.

[0015] The utility model has the following beneficial effects:

[0016] 1. By arranging the conveying mechanism, when the plastic-absorbed and formed material is placed on the conveyor belt, the motor on the motor sleeve is started at this time. The motor drives the semi-gear to rotate through the second rotating shaft. The semi-gear drives the first rotating shaft to rotate intermittently through the gear, so as to drive the conveyor belt to rotate through the round roller, and transport the material on the conveyor belt forward, so that the material can be automatically transported to directly below the cutting knife. After the dividing mechanism cuts it, the cut material can be transported to other areas, which can maintain the stable transportation of the material, ensure the accuracy and consistency of the cutting or other processing processes, reduce the influence of human factors on the product quality, and can also speed up the production speed, reduce the pauses and waiting times in the production process, thereby improving the overall production efficiency;

[0017] 2. By setting up a splitting mechanism, when the second rotating shaft drives the conveyor belt to rotate, it will also drive the third rotating shaft on the support plate to rotate through the pulley and the belt. The third rotating shaft drives the threaded cylinder to lift through the trapezoidal gear. When the threaded cylinder lifts, it will drive the lifting plate in the trapezoidal groove to lift, thereby driving the splitting blade to lift and cut the materials on the conveyor belt. Whenever the semi-gear rotates one week, the reciprocating lead screw on the U-shaped support frame completes one lift, so as to ensure that the size of the plastic products meets the requirements of the product design, guarantee the accuracy and consistency of the products, and can cooperate with the conveying mechanism. The conveying mechanism automatically conveys the processed plastic products to the splitting mechanism, and then automatically conveys them to the next workstation after cutting, realizing the continuity of the production process and reducing the production interruption time.

[0018] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figure 1-5 As shown, the present invention is a thermoforming splitting machine, including support legs 1, on which a conveyor mechanism 11 and a splitting mechanism 2 are provided;

[0029] The conveyor mechanism 11 includes a first rotating shaft 111 rotatably connected between two support legs 1. The two first rotating shafts 111 are arranged on the left and right sides of the two support legs 1. The front end of the first rotating shaft 111 on the left rotates through the outer wall of the front support leg 1 and extends to the outside. Circular rollers 112 are fixedly connected to both first rotating shafts 111, and a conveyor belt 113 is sleeved on the two circular rollers 112.

[0030] Among them, as Figure 4 shown, the splitting mechanism 2 includes a cutting assembly 21, a first transmission assembly 22, and a second transmission assembly 23. The cutting assembly 21 includes a C-shaped support frame 211 fixedly connected to two support legs 1, and a threaded cylinder 212 rotatably penetrates through the central axis of the C-shaped support frame 211.

[0031] By setting the splitting mechanism 2, it can ensure that the size of the plastic product meets the requirements of the product design, guarantee the accuracy and consistency of the product, and can cooperate with the conveyor mechanism. The conveyor mechanism automatically conveys the processed plastic products to the splitting mechanism, and then automatically conveys them to the next workstation after cutting, realizing the continuity of the production process and reducing the production interruption time.

[0032] Among them, as Figure 3 and Figure 4As shown, a reciprocating lead screw 213 is threadedly connected to the inner wall of the threaded cylinder 212, and trapezoidal grooves 214 are formed in the front and rear inner walls of the U-shaped support frame 211.

[0033] By providing the threaded cylinder 212, when the threaded cylinder 212 rotates, it drives the reciprocating lead screw 213 to move up and down, thereby driving the dividing blade 216 to cut the material on the conveyor belt 113.

[0034] As Figure 3 shown, a lifting plate 215 is slidably connected to the inner walls of the two trapezoidal grooves 214. The top of the lifting plate 215 is rotatably connected to the reciprocating lead screw 213, and the bottom of the lifting plate 215 is fixedly connected to a dividing blade 216.

[0035] By providing the trapezoidal grooves 214, a sliding space can be provided for the movement of the lifting plate 215, making the sliding of the lifting plate 215 smoother.

[0036] As Figure 4 shown, a rotating groove 217 is formed at the central axis of the U-shaped support frame 211. A snap ring 218 is fixedly connected to the outer wall of the threaded cylinder 212, and the outer wall of the snap ring 218 extends into the rotating groove 217 and is rotatably connected to the rotating groove 217.

[0037] By providing the rotating groove 217 and the snap ring 218, a rotational limit can be provided for the rotation of the threaded cylinder 212, making the rotation of the threaded cylinder 212 more stable.

[0038] As Figure 5 shown, the first transmission assembly 22 includes a second rotating shaft 221 rotatably connected to the front support leg 1. A gear 222 is fixedly connected to the outer wall of the conveying mechanism 11. A half gear 223 is fixedly connected to the outer wall of the second rotating shaft 221. The gear 222 meshes with the half gear 223. A motor 224 is fixedly connected to the front side of the second rotating shaft 221. A motor sleeve 225 is fixedly connected to the outer wall of the motor 224, and the rear side of the motor sleeve 225 is fixedly connected to the front support leg 1.

[0039] By providing the first transmission assembly 22, when the motor 224 is started, the motor 224 drives the half gear 223 to rotate through the second rotating shaft 221, and the half gear 223 drives the first rotating shaft 111 to rotate intermittently through the gear 222.

[0040] As Figure 4 and Figure 5As shown in the figure, two support plates 226 are fixedly connected to the top of the U-shaped support frame 211. A third rotating shaft 228 is rotatably connected between the two support plates 226. The front side and the rear side of the third rotating shaft 228 respectively rotatably penetrate the outer walls of the two support plates 226 and extend to the outside. Trapezoidal gears 229 are fixedly connected to both the threaded cylinder 212 and the third rotating shaft 228, and the two trapezoidal gears 229 are meshed with each other.

[0041] By setting the trapezoidal gears 229, the transmission becomes more stable, reducing the meshing impact and vibration between the gears, which helps to extend the service life of the equipment and improve the production quality.

[0042] Among them, as Figure 2 and Figure 5 shown in the figure, the second transmission assembly 23 includes pulley wheels 231 respectively fixedly connected to the second rotating shaft 221 and the third rotating shaft 228, and a belt 232 is sleeved on the two pulley wheels 231.

[0043] By setting the second transmission assembly 23, when the second rotating shaft 221 drives the conveyor belt 113 to rotate, the second rotating shaft 221 will drive the third rotating shaft 228 on the support plate 226 to rotate through the pulley wheels 231 and the belt 232.

[0044] A specific application of this embodiment is as follows: During use, first place the plastic thermoformed material on the conveyor belt 113. At this time, start the motor 224 on the motor sleeve 225. The motor 224 drives the half gear 223 to rotate through the second rotating shaft 221. The half gear 223 drives the first rotating shaft 111 to rotate intermittently through the gear 222, thereby driving the conveyor belt 113 to rotate through the round roller 112, transporting the material on the conveyor belt 113 forward, so that the material can be automatically transported to directly below the cutting knife. After the dividing mechanism 2 cuts it, the cut material can be transported to other areas, which can maintain the stable transportation of the material, ensure the accuracy and consistency of the cutting or other processing processes, reduce the influence of human factors on the product quality, and can also speed up the production speed, reduce the pauses and waiting times during the production process, thereby improving the overall production efficiency. When the second rotating shaft 221 drives the conveyor belt 113 to rotate, it will also drive the third rotating shaft 228 on the support plate 226 to rotate through the pulley 231 and the belt 232. The third rotating shaft 228 drives the threaded cylinder 212 to move up and down through the trapezoidal gear 229. When the threaded cylinder 212 moves up and down, it will drive the lifting plate 215 in the trapezoidal groove 214 to move up and down, thereby driving the dividing blade 216 to move up and down to cut the material on the conveyor belt 113. Whenever the half gear 223 rotates one week, the reciprocating lead screw 213 on the U-shaped support frame 211 completes one up and down movement, so as to ensure that the size of the plastic product meets the requirements of the product design, and ensure the accuracy and consistency of the product. It can cooperate with the conveying mechanism 11. The conveying mechanism 11 automatically conveys the processed plastic products to the dividing mechanism 2, and then automatically conveys them to the next workstation after cutting, realizing the continuity of the production process and reducing the production interruption time.
