Description

Technical Field

[0001] This utility model relates to the field of bar processing technology, specifically a plastic bar processing device. Background Technology

[0002] Plastic rod processing is the process of shaping high-molecular polymer raw materials into rod-shaped profiles through extrusion, cutting, injection molding, and other processes. It is widely used in machinery manufacturing, electronics, and home furnishings. The raw materials include polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC). The materials are heated and melted in an extruder at a temperature controlled between 180-250℃, extruded through a die, cooled and shaped, and then cut into rods at a water temperature controlled between 20-30℃. However, existing rod processing equipment still has certain problems in use:

[0003] For example, a bar stock processing device with application number 201510432807.7 has the following technical solution: it consists of an electric motor, flywheel, pinion gear, large gear, clutch, crankshaft, slider, electromagnet, belt drive, worm gear, sprocket, roller, and roller. The electric motor is the power source, which drives the flywheel on the main shaft through the belt drive. The main shaft transmits the rotational motion to the pinion gear, which meshes with the large gear. The electromagnet controls the clutch, so that the crankshaft and the large gear move synchronously. The crankshaft drives the slider to move up and down, and the bar stock cutting tool is installed on the slider and moves with the slider to realize bar stock shearing. However, the existing bar stock shearing equipment has significant defects in loading efficiency and functional adaptability, which significantly restricts production efficiency. Traditional loading relies on manual handling and manual positioning, which has certain production errors and cannot adapt to various processing forms, resulting in low production efficiency.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing bar stock processing equipment. Utility Model Content

[0006] The purpose of this utility model is to provide a plastic rod processing device to solve the problems mentioned in the background art, such as the cumbersome feeding process for rod shearing and the inability to adapt to multiple processing functions.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A plastic rod processing device includes a feeding rack, an inlet plate at the rear of the feeding rack, and a discharge conveyor platform at the front of the feeding rack. A processing vertical plate is located on the left side of the feeding rack, and a discharge platform is fixedly installed in the middle of the front side of the processing vertical plate. The feeding rack is sloping with a higher rear and lower front, and a track groove is provided inside the feeding rack. Two conveyor plates are rotatably connected in the middle of the feeding rack. A pneumatic telescopic mechanism is fixedly installed on the right side of the discharge conveyor platform, and a push plate is connected to the output end of the pneumatic telescopic mechanism. Two lifting plates are located in front of the processing vertical plate, and the lifting plates form a reciprocating up-and-down movement structure by eccentric rotation.

[0009] Preferably, a drive motor is fixedly installed on the right side of the feeding rack, and a first rotating rod is connected and installed on the left output end of the drive motor. The transport tray is fixedly installed on the left and right sides of the first rotating rod to form a rotating structure, and limit grooves are opened on the edges of the transport tray.

[0010] Using the above technical solution, the limiting groove on the edge of the transport tray is linked with the first rotating rod, and the plastic rod is automatically fed by rotation, which replaces the traditional manual handling and positioning, reduces operation error, improves feeding efficiency and consistency, and is suitable for continuous production processes.

[0011] Preferably, the track trough is fixedly installed on the left and right sides inside the feeding rack, and the track trough is semi-arc-shaped, and the track trough is connected between the feeding plate and the discharging conveyor.

[0012] Using the above technical solution, the semi-circular track plate is fixed inside the feeding rack, guiding the bar stock to slide smoothly along the preset path, effectively preventing the bar stock from deviating or getting stuck on the inclined surface. Combined with the limiting groove, it achieves precise positioning, ensuring that the bar stock accurately enters the subsequent processing station and improving the reliability of feeding.

[0013] Preferably, the left end of the first rotating rod extends through the left side of the feeding frame, and a transmission belt is connected and installed above the left end of the first rotating rod. A second rotating rod is connected and installed above the transmission belt, and tensioning pulleys are provided on the outer side of the transmission belt connection end.

[0014] By adopting the above technical solution, the combination of transmission belt and tension pulley stably transmits the power of drive motor to the second rotating rod. By adjusting the tension pulley, the tension of the transmission system is maintained to avoid slippage or power loss, ensuring that the transport tray and lifting tray operate synchronously and guaranteeing the coordination of processing rhythm.

[0015] Preferably, a first bevel gear is connected and installed on the left side of the second rotating rod, and a second bevel gear is meshed with the front side of the first bevel gear, and a first gear is connected and installed on the front side of the second bevel gear.

[0016] By adopting the above technical solution, the first bevel gear and the second bevel gear form a vertical transmission structure, which converts the horizontal rotational motion of the second rotating rod into the vertical rotational motion of the first gear, optimizes the spatial layout of the equipment, adapts to the narrow design of the vertical plate, and meets the needs of compact production.

[0017] Preferably, a second gear is meshed below the first gear, and both the first and second gears are eccentrically connected to a lifting plate via a rotating shaft, and a cutting blade is fixedly installed on the side of the lifting plate near the discharge table.

[0018] Using the above technical solution, the first gear meshes with the second gear to drive the lifting plate to rotate eccentrically, causing the cutting blade to reciprocate up and down, thereby realizing the automated cutting of plastic rods, replacing the traditional manual cutting method, improving cutting efficiency and cutting accuracy, and reducing the intensity of manual labor.

[0019] Preferably, the lifting plate is equipped with a drilling head connected to a motor on the side near the discharge platform.

[0020] Using the above technical solution, the lifting plate integrates a drilling head, which immediately performs drilling operations on the end face of the bar stock after the cutting process is completed. It achieves two functions in one processing cycle, reducing equipment changeover time and floor space, improving production line integration and production efficiency, and adapting to diverse processing needs.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the plastic rod processing device,

[0022] 1. Automated feeding and precise positioning: The inclined design of the feeding rack, combined with the limiting groove of the transport tray, enables gravity self-sliding and intermittent conveying of plastic rods without manual intervention, improving feeding efficiency. The semi-circular guide structure of the track plate reduces the positioning error of the rods, ensuring the accuracy of subsequent processing. The push plate of the pneumatic telescopic machine pushes the rods to the discharge table with an appropriate response speed, precisely matching the processing rhythm of the lifting plate, avoiding empty material or accumulation.

[0023] 2. Multifunctional integrated processing to improve production efficiency: The drive motor drives the transport plate and the lifting plate simultaneously through the transmission belt, bevel gear set and gear set to realize the integrated operation of "feeding-cutting-drilling". A single machine can complete the traditional multi-machine process, improving production efficiency. The eccentric rotation mechanism of the lifting plate is compatible with cutting blades and drilling heads. By changing the blades, the processing mode can be quickly switched to adapt to various needs such as cutting, chamfering and drilling of plastic rods, improving functional adaptability.

[0031] Example 1

[0032] Please see Figure 1-4 This utility model provides a technical solution:

[0033] A plastic rod processing device includes a feeding rack 1, an infeed plate 3 at the rear of the feeding rack 1, and a discharge conveyor 4 at the front of the feeding rack 1. A processing vertical plate 10 is provided on the left side of the feeding rack 1, and a discharge platform 11 is fixedly installed in the middle of the front side of the processing vertical plate 10. The feeding rack 1 is sloping with a higher rear and lower front, and a track groove plate 2 is provided inside the feeding rack 1.

Two lifting plates 18 are provided in the front side of the processing vertical plate 10, and the lifting plates 18 form a reciprocating up-and-down movement structure by eccentric rotation.

[0034] The track trough 2 is fixedly installed on the left and right sides inside the loading rack 1. The track trough 2 is semi-arc-shaped and is connected between the feed plate 3 and the discharge conveyor 4. The semi-arc track trough 2 is fixed inside the loading rack 1 to guide the bar stock to slide smoothly along the preset path, effectively preventing the bar stock from deviating or getting stuck on the inclined surface. It works with the limiting groove 8 to achieve precise positioning, ensuring that the bar stock accurately enters the subsequent processing station and improving the reliability of loading.

[0035] A drive motor 5 is fixedly installed on the right side of the loading rack 1, and a first rotating rod 6 is connected to the output end of the drive motor 5 on the left side. A transport tray 7 is fixedly installed on both sides of the first rotating rod 6 to form a rotating structure, and limit grooves 8 are opened on the edges of the transport tray 7. The left end of the first rotating rod 6 passes through the left side of the loading rack 1, and a transmission belt 12 is connected to the upper left end of the first rotating rod 6. A second rotating rod 13 is connected to the upper part of the transmission belt 12, and tensioning pulleys are provided on the outer side of the connecting end of the transmission belt 12. The limit grooves 8 on the edge of the transport tray 7 are linked with the first rotating rod 6. The automatic feeding of plastic rods is achieved by rotation, replacing the traditional manual handling and positioning, reducing operation errors, improving feeding efficiency and consistency, and is suitable for continuous production processes. The combination of the transmission belt 12 and the tensioning pulley stably transmits the power of the drive motor 5 to the second rotating rod 13. By adjusting the tensioning pulley, the tension of the transmission system is maintained to avoid slippage or power loss, ensuring that the transport tray 7 and the lifting tray 18 operate synchronously and ensuring the coordination of the processing rhythm.

[0036] The left end of the second rotating rod 13 is connected to and installed with a first bevel gear 14, and the front side of the first bevel gear 14 is meshed with a second bevel gear 15.

This optimizes the spatial layout of the equipment, adapts to the narrow design of the processing vertical plate 10, and meets the needs of compact production. The meshing of the first gear 16 and the second gear 17 drives the lifting plate 18 to rotate eccentrically, causing the cutting blade 19 to reciprocate up and down, realizing the automated cutting of plastic rods, replacing the traditional manual cutting method, improving cutting efficiency and cutting accuracy, and reducing the intensity of manual labor.

Two functions are achieved in one processing cycle, reducing equipment changeover time and floor space, improving the integration of the production line and production efficiency, and adapting to diverse processing needs.

[0040] Working principle:

[0041] In use, the plastic rod is placed from the feed plate 3 into the feeding rack 1 and slides down the semi-arc track of the track trough 2 into the limiting groove 8 of the transport tray 7. The drive motor 5 drives the first rotating rod 6 to rotate, and the transport tray 7 intermittently transports the rod to the discharge transport table 4. The push plate of the pneumatic telescopic machine 9 pushes the rod to the discharge table 11. The first rotating rod 6 drives the second rotating rod 13 to rotate through the transmission belt 12. The first bevel gear 14 meshes with the second bevel gear 15, driving the first gear 16 and the second gear 17 to rotate in opposite directions.
