Description

Technical Field

[0001] The utility model relates to the field of straw production, in particular to a plastic straw extrusion molding device. Background Art

[0002] The plastic straw extrusion molding device is a device used to produce plastic straws. The extruder is the core component of the entire production line. It heats the plastic particles to a molten state and then pushes the molten plastic into a mold to form the shape of the straw. The extruder is usually composed of a heating element, a screw, a drive system and a control system. When some extruders are in use, workers will put a large amount of products into the feed box, while some feed boxes feed continuously, which may cause the product to accumulate at the feed port of the extruder, increase the processing load of the extruder, and the practicality is too low.

[0003] After searching, Chinese patent announcement number: CN218892193U discloses a plastic straw extrusion device, including a driving component and an extrusion barrel and a second screw rod rotatably connected to the extrusion barrel, the extrusion barrel is movably connected to a lower bin, a first screw rod connected to the lower bin is rotatably arranged, and a dispersion rod is arranged in a linear array on the first screw rod. The plastic straw extrusion device provided by the utility model utilizes a driving component. When the plastic raw material is put into the lower bin, the second screw rod and the first screw rod are driven to rotate by the driving component at the same time, so that the raw material slides along the lower bin to the discharge port, and at the same time, the heating plate heats the raw material through the fan to blow hot air onto the raw material, so that the raw material is quickly air-dried. As the raw material accumulates, it slides from the lower pipe into the extrusion barrel, and then the raw material is extruded and heated, thereby quickly removing water stains on the raw material without hindering the production of straws, so as to improve work efficiency.

[0037] Working principle: When unloading, workers can put the products into the unloading box 2. Some of the products entering the unloading box 2 will enter the gap of the unloading column 42. At this time, the motor 41 can be started, and the motor 41 drives the unloading column 42 to rotate. At this time, the unloading column 42 will send the products entering the inner wall of the top gap into the extruder 1, and then the bottom gap will rotate to the inside of the unloading box 2 to collect the products, and continue to rotate to feed. In this way, intermittent unloading can be achieved, reducing the load on the extruder 1. When the amount of unloading needs to be adjusted, it is only necessary to pull the pull rod 46, and the pull rod 46 will pull The spring 48 is stretched, and the pull rod 46 drives the gear 49 to move until the gear 49 is completely out of the inner wall of the engaging groove 410. At this time, the connecting plate 43 can be rotated, and the connecting plate 43 drives the round rod 44 to slide on the inner wall of the arc-shaped through groove 47. The round rod 44 drives the adjusting block 45 to rotate about the center of the lower material column 42, so as to achieve the purpose of adjusting the size of the gap of the lower material column 42. After the adjustment is completed, the pull rod 46 can be loosened. At this time, the spring 48 will pull the pull rod 46 to move in the opposite direction through its own elasticity, and the pull rod 46 will drive the gear 49 to move in the opposite direction and insert into the inner wall of the engaging groove 410, thereby limiting the connecting plate 43.

[0038] When the extrusion die 3 needs to be replaced, it is only necessary to rotate the bidirectional threaded rod 52. At this time, the arc plate 51 threadedly connected to its outer wall will drive the limiting rod 53 to move linearly until the limiting rod 53 is completely separated from the inner wall of the groove provided on the left front surface of the extruder 1. At this time, the extrusion die 3 can be disassembled. When installing, align the positioning block 54 with the positioning groove 6, and then push the positioning block 54 into the inner wall of the positioning groove 6. At this time, the outer wall of the left end of the extruder 1 will enter the inner wall of the extrusion die 3. Then reverse the bidirectional threaded rod 52 so that the limiting rod 53 is inserted into the inner wall of the groove to complete the installation. It is quick and convenient, and improves work efficiency.
