Description

Technical Field

[0001] This utility model relates to the technical field of plastic processing and cutting equipment, and in particular to a fixed-point cutting equipment for plastic product processing. Background Technology

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastics. They include all products manufactured using plastics through processes such as injection molding and thermoforming. Among these are plastic sheets. In the field of plastic product processing, sheet cutting is a crucial step, as it not only affects the dimensional accuracy and appearance quality of the product but also directly impacts production efficiency and material utilization.

[0003] In the process of cutting scrap plastic sheets, the traditional cutting method usually involves fixing and clamping one side of the sheet, and then moving the cutting equipment to cut the remaining material longitudinally, with the resulting scrap material piling up on the work platform.

[0004] Therefore, to address the aforementioned inconvenience in achieving precise cutting and automatic recycling of leftover plastic sheet material, a plastic product processing precision cutting device can be designed. During operation, activating the longitudinal movement component allows the sliding component to drive the cutting component, enabling precise cutting of leftover plastic sheet material. Furthermore, the adjusting gear drives the adjusting shaft and the discharge rack to rotate, allowing the leftover material to fall smoothly into the collection box below. This achieves precise cutting and automatic recycling of leftover plastic sheet material, significantly improving processing efficiency and material utilization. Utility Model Content

[0005] In order to overcome the problems that traditional cutting methods are usually semi-automatic mechanical processing, which makes it difficult to ensure accurate cutting of large quantities of sheet material and the inability to remove excess material in a timely manner, a fixed-point cutting equipment for plastic product processing needs to be improved. This makes it inconvenient to achieve fixed-point cutting and automatic recycling of excess material from plastic sheets.

[0006] The technical solution of this utility model is as follows: a plastic product processing fixed-point cutting equipment, including a platform, a sheet rack, a connecting frame, an adjusting toothed plate, an adjusting shaft, a spiral spring, an adjusting gear, a discharge rack, a contact plate, a collection box, a guide assembly, a transverse moving assembly, a sliding assembly, a cutting assembly, and a longitudinal moving assembly. A guide assembly is provided on one side of the bottom wall of the platform, and a sheet rack is provided above the guide assembly. A transverse moving assembly is provided on one side of the bottom wall of the platform. An adjusting shaft is provided on the inner wall of the other side of the platform. A discharge rack is provided on the side wall of the adjusting shaft. A contact plate is provided inside the discharge rack. Two sets of spiral springs are provided at both ends of the adjusting shaft. An adjusting gear is provided on the side wall of one end of the adjusting shaft.

A longitudinal moving assembly is provided on the bottom wall of the cutting assembly.

[0007] Preferably, during the use of the plastic processing and cutting equipment, firstly, the plastic sheet to be cut is properly placed inside the sheet rack. Then, activating the transverse movement component allows the sheet rack and the plastic sheet it carries to move laterally via the guide component. When the tail end of the plastic sheet contacts the abutment plate inside the discharge rack, the sheet's movement is effectively blocked, achieving precise positioning of the plastic sheet. Simultaneously, activating the cutting component enables high-speed rotation, while activating the longitudinal movement component allows the cutting component to move longitudinally via the sliding component, thereby precisely cutting off any excess material from the plastic sheet. After cutting, the cut-off material naturally falls into the discharge rack. Next... Next, the translation component is activated again, driving the connecting frame and adjusting toothed plate to move laterally. The adjusting toothed plate meshes with the adjusting gear on the adjusting shaft, driving the adjusting shaft and the discharge rack to rotate, allowing the leftover material to fall smoothly into the collection box below, realizing the automatic recycling and storage of the leftover material. When the adjusting toothed plate moves in the reverse direction, the adjusting gear drives the adjusting shaft and the discharge rack to reset and reverse again. In addition, the elastic characteristics of the spiral spring ensure that the adjusting shaft and the discharge rack remain stable during rotation, avoiding shaking or deviation. In summary, through a series of precise mechanical transmission designs, this equipment realizes the fixed-point cutting and automatic recycling of leftover plastic sheet material, greatly improving processing efficiency and material utilization.

[0008] Preferably, one end of the spiral spring is fixedly connected to one end of the adjusting shaft, and the other end of the spiral spring is fixedly connected to the inner wall of the platform, with the adjusting tooth plate meshing with the adjusting gear.

[0009] Preferably, the guiding assembly includes a guide rod, a guide block, and a guide frame. A guide rod is provided on one bottom wall of the platform, and two sets of guide blocks are provided on the side wall of the guide rod. The guide blocks are slidably connected to the guide rod, and a guide frame is provided above the guide blocks. A sheet metal rack is provided above the guide frame.

[0010] Preferably, the transverse component includes a fixed frame, a rotating motor, a rotating shaft, a rotating gear, and a movable toothed plate. The movable toothed plate is located below the guide block. The fixed frame is located on one side of the bottom wall of the platform. The rotating motor is located inside the fixed frame. The rotating shaft is located at the output end of the rotating motor. The rotating gear is located at one end of the rotating shaft. The rotating gear meshes with the movable toothed plate. The connecting frame is located at one end of the movable toothed plate.

[0011] Preferably, the sliding assembly includes a support frame, a sliding rod, and a sliding block. The support frame is provided on the bottom wall of the platform, the sliding rod is provided inside the support frame, and the sliding block is provided on the side wall of the sliding rod. The sliding block is slidably connected to the sliding rod.

[0012] Preferably, the cutting assembly includes a mounting bracket, a drive motor, a drive shaft, and a cutting blade. The mounting bracket is provided on the side wall of the sliding block, the drive motor is provided inside the mounting bracket, the drive shaft is provided at the output end of the drive motor, and the cutting blade is provided at one end of the drive shaft.

[0013] Preferably, the longitudinal movement assembly includes a fixed toothed plate, a stabilizing frame, a drive motor, a drive shaft, and a drive gear. The stabilizing frame is provided on the bottom wall of the mounting frame, the drive motor is provided inside the stabilizing frame, the drive shaft is provided at the output end of the drive motor, and the drive gear is provided at one end of the drive shaft. The fixed toothed plate is provided on the bottom wall of the support frame, and the drive gear meshes with the fixed toothed plate.

[0014] The beneficial effects of this utility model are:

[0015] When using the plastic processing and cutting equipment, firstly, the plastic sheet to be cut is properly placed inside the sheet rack. Then, activating the transverse movement component moves the sheet rack and the plastic sheet it carries laterally via the guide component. When the tail end of the plastic sheet contacts the abutment plate inside the discharge rack, the sheet's movement is effectively stopped, achieving precise positioning. Simultaneously, activating the cutting component enables high-speed rotation, while activating the longitudinal movement component moves the cutting component longitudinally via the sliding component, thus precisely cutting off any excess material from the plastic sheet. After cutting, the cut-off material naturally falls into the discharge rack. Next... The translation component is restarted, driving the connecting frame and adjusting toothed plate to move laterally. The adjusting toothed plate meshes with the adjusting gear on the adjusting shaft, driving the adjusting shaft and the discharge rack to rotate, allowing the leftover material to fall smoothly into the collection box below, achieving automatic recycling and storage of the leftover material. When the adjusting toothed plate moves in the reverse direction, the adjusting gear drives the adjusting shaft and the discharge rack to reset and reverse again. In addition, the elastic characteristics of the spiral spring ensure that the adjusting shaft and the discharge rack remain stable during rotation, avoiding shaking or deviation. In summary, this equipment, through a series of precise mechanical transmission designs, achieves point-to-point cutting and automatic recycling of leftover plastic sheet material, greatly improving processing efficiency and material utilization.

[0024] Please see Figure 2 and Figure 3One end of the spiral spring 6 is fixedly connected to one end of the adjusting shaft 5, and the other end of the spiral spring 6 is fixedly connected to the inner wall of the platform 1. The adjusting gear plate 4 meshes with the adjusting gear 7. The elastic characteristics of the spiral spring 6 ensure that the adjusting shaft 5 and the material rack 8 remain stable during rotation, avoiding shaking or deviation. The guide assembly includes a guide rod 101, a guide block 102, and a guide frame 103. A guide rod 101 is provided on one side of the bottom wall of the platform 1, and two sets of guide blocks 102 are provided on the side wall of the guide rod 101. The guide blocks 102 are slidably connected to the guide rod 101, and a guide frame 103 is provided above the guide blocks 102. The plate rack 2 is located above the guide frame 103 and is stably supported by the sliding connection between the guide blocks 102 and the guide rod 101. At the same time, the guide blocks 102 also push the plate rack 2 through the guide frame 103 connected above. The lateral movement component includes a fixed frame 201, a rotating motor 202, a rotating shaft 203, a rotating gear 204, and a moving toothed plate 205. The moving toothed plate 205 is located below the guide block 102. The fixed frame 201 is located on one side of the bottom wall of the platform 1. The rotating motor 202 is located inside the fixed frame 201. The rotating shaft 203 is located at the output end of the rotating motor 202. The rotating gear 204 is located at one end of the rotating shaft 203. The rotating gear 204 meshes with the moving toothed plate 205. The connecting frame 3 is located at one end of the moving toothed plate 205. When the rotating motor 202 is started, the rotating motor 202 drives the rotating gear 204 to rotate through the rotating shaft 203 at its output end. The rotating gear 204 meshes tightly with the moving toothed plate 205, thus enabling the moving toothed plate 205 to move laterally.

[0025] Please see Figure 4 and Figure 5The sliding assembly includes a support frame 301, a sliding rod 302, and a sliding block 303. The support frame 301 is mounted on the bottom wall of the platform 1. The sliding rod 302 is located inside the support frame 301, and the sliding block 303 is mounted on the side wall of the sliding rod 302. The sliding block 303 is slidably connected to the sliding rod 302, and moves longitudinally via the sliding rod 302, ensuring smooth cutting. The cutting assembly includes a mounting frame 401, a drive motor 402, a drive shaft 403, and a cutting blade 404. The mounting frame 401 is mounted on the side wall of the sliding block 303. The drive motor 402 is located inside the mounting frame 401. The drive shaft 403 is located at the output end of the drive motor 402, and the cutting blade 404 is located at one end of the drive shaft 403. When the drive motor 402 is started, the drive motor 402... The drive shaft 403 drives the cutting blade 404 to rotate at high speed, thereby accurately cutting the excess material from the plastic sheet. The longitudinal movement assembly includes a fixed toothed plate 501, a stabilizing frame 502, a drive motor 503, a drive shaft 504, and a drive gear 505. The stabilizing frame 502 is provided on the bottom wall of the mounting frame 401. The drive motor 503 is located inside the stabilizing frame 502. The drive shaft 504 is provided at the output end of the drive motor 503. The drive gear 505 is provided at one end of the drive shaft 504. The fixed toothed plate 501 is provided on the bottom wall of the support frame 301. The drive gear 505 meshes with the fixed toothed plate 501. When the drive motor 503 is started, it drives the drive gear 505 to rotate through the drive shaft 504. The interaction between the drive gear 505 and the fixed toothed plate 501 can push the entire cutting assembly to move longitudinally.

[0026] When the plastic processing and cutting equipment is in use, firstly, the plastic sheet to be cut is properly placed inside the sheet rack 2. Then, the rotating motor 202 is started. The rotating motor 202 drives the rotating gear 204 to rotate through the rotating shaft 203 at its output end. The rotating gear 204 meshes tightly with the moving toothed plate 205, thus driving the moving toothed plate 205 to move laterally along the guide rod 101. This movement is stably supported by the sliding connection between the guide block 102 and the guide rod 101. At the same time, the guide block 102 also pushes the sheet rack 2 and the plastic sheet it carries to move laterally together through the guide frame 103 connected above. When the tail end of the plastic sheet comes into contact with the abutment plate 9 set inside the discharge rack 8, the movement of the sheet is effectively blocked, achieving precise positioning of the plastic sheet.

[0027] At this time, the rotary motor 202 is turned off, and the drive motor 402 is started. The drive motor 402 drives the cutting blade 404 to rotate at high speed through the drive shaft 403. At the same time, the active motor 503 is started, which drives the active gear 505 to rotate through the active shaft 504. The active gear 505 interacts with the fixed toothed plate 501, pushing the entire mounting frame 401, drive motor 402, drive shaft 403, and rotating cutting blade 404 to move longitudinally, thereby accurately cutting the excess material from the plastic sheet. During the cutting process, the mounting frame 401 also drives the sliding block 303 to move longitudinally along the sliding rod 302, ensuring the smooth operation of the cutting action.

[0028] After cutting is completed, the active motor 503 and drive motor 402 are turned off, and the cut-off scrap naturally falls into the discharge rack 8. Next, the rotary motor 202 is restarted. Through a series of gear and shaft transmissions, the moving gear plate 205 drives the connecting frame 3 and the adjusting gear plate 4 to move laterally. The adjusting gear plate 4 meshes with the adjusting gear 7 on the adjusting shaft 5, driving the adjusting shaft 5 and the discharge rack 8 to rotate, allowing the scrap to fall smoothly into the collection box 10 below, realizing the automatic recycling and storage of scrap.

[0029] When the adjusting gear plate 4 moves in the reverse direction, the adjusting gear 7 drives the adjusting shaft 5 and the discharge rack 8 to reset and reverse again. In addition, the elastic characteristics of the spiral spring 6 ensure that the adjusting shaft 5 and the discharge rack 8 remain stable during rotation, avoiding shaking or deviation.

[0030] In summary, through a series of precise mechanical transmission designs, this equipment achieves point-to-point cutting and automatic recycling of leftover plastic sheet material, greatly improving processing efficiency and material utilization.

[0031] Through the above steps, when the plastic processing and cutting equipment is in use, firstly, the plastic sheet to be cut is properly placed inside the sheet rack 2. Then, the transverse movement component is activated, which, through the guide component, drives the sheet rack 2 and the plastic sheet it carries to move laterally. When the tail end of the plastic sheet contacts the abutment plate 9 set inside the discharge rack 8, the movement of the sheet is effectively blocked, achieving precise positioning of the plastic sheet. Then, the cutting component is activated to achieve high-speed rotation. Simultaneously, the longitudinal movement component is activated, which, through the sliding component, drives the cutting component to achieve longitudinal movement, thereby precisely cutting the excess material from the plastic sheet. After cutting, the cut-off excess material naturally falls into the discharge rack 8. Next, the process continues... The activation of the translation component drives the connecting frame 3 and the adjusting toothed plate 4 to move laterally. The adjusting toothed plate 4 meshes with the adjusting gear 7 on the adjusting shaft 5, driving the adjusting shaft 5 and the discharge rack 8 to rotate, allowing the residual material to fall smoothly into the collection box 10 below, realizing the automatic recycling and storage of the residual material. When the adjusting toothed plate 4 moves in the reverse direction, the adjusting gear 7 drives the adjusting shaft 5 and the discharge rack 8 to reset and reverse again. In addition, the elastic characteristics of the spiral spring 6 ensure that the adjusting shaft 5 and the discharge rack 8 remain stable during rotation, avoiding shaking or deviation. In summary, through a series of precise mechanical transmission designs, this equipment realizes the fixed-point cutting and automatic recycling of residual material from plastic sheets, greatly improving processing efficiency and material utilization.
