[0001] The utility model relates to the technical field of plastic particle processing, in particular to a feeding and drying device for guide block injection molding. Background Art
[0002] A major component of a motorcycle is the transmission wheel, which generally refers to the transmission gear. Currently, an important component of the transmission wheel is the guide block, and the guide block is generally processed by injection molding, that is, the plastic particles are melted and injected into the molding mold, and then the molded guide block is taken out from the molding mold after cooling. This process is currently most commonly completed by a plastic injection molding machine.
[0003] Plastic injection molding machine is also called injection molding machine. Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. The feeding port of the injection molding machine is located at a high position, especially for large injection molding machines. The feeding method has high operating risks and low working efficiency.
[0004] In addition, most of the existing injection molding machine feeding devices are not equipped with drying functions. The humidity of the raw materials will directly affect the quality of the injection molded products. The surface of the plastic particles stored in the hopper may contain moisture, which forms bubbles during the melting process of the plastic. This causes pore defects inside the produced plastic products, affecting the strength of the plastic products.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:
[0029] like Figure 1 and Figure 2 As shown, a feeding and drying device for guide block injection molding includes an inclined feeding auger 1, the feeding auger 1 includes a feed hopper 11 and the output end of the feeding auger 1 is connected to the plastic injection molding equipment, the feed hopper 11 is provided with a processing box 2 with an open bottom and the processing box 2 is communicated with the feed hopper 11, a feed port 201 is provided on one side wall of the processing box 2, and a deflectable blocking component and a turning component above the blocking component and not affecting the rotation of the blocking component are provided in the processing box 2, a heating plate 211 is provided on the blocking component, and a cylinder 23 is provided on the processing box 2, and the cylinder 23 is connected to a blocking block 24 matched with the feed port 201.
[0030] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 2 As shown, the blocking assembly includes a blocking plate 21 and a servo motor 22. Rollers rotatably connected to the processing box 2 are arranged at both ends of the blocking plate 21. The rollers are shown unnumbered in the figure. One of the rollers passes through the processing box 2 and is connected to the servo motor 22 fixed on the outer wall of the processing box 2. A heating plate 211 is arranged on the blocking plate 21.
[0031] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 2 As shown, the turning assembly includes a driving motor 31, a turning shaft 32 and a turning rod 33. The processing box 2 is provided with a driving motor 31, and the driving motor 31 is connected to the turning shaft 32 rotatably connected inside the processing box 2. The turning shaft 32 is provided with a row of turning rods 33 on the same side.
[0032] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, a vibration motor 12 is provided on the feed hopper 11 ; the probability of accumulation and clogging of plastic particles in the feed hopper 11 can be reduced by means of the vibration motor 12 .
[0033] It should be noted that the feeding auger 1, the servo motor 22, the heating plate 211, the drive motor 31, the vibration motor 12 and the cylinder 23 are all electrically connected to the controller, which is not shown in the figure.
[0034] The workflow of this utility model:
[0035] When preparing to feed, the controller controls the cylinder 23 to contract so that the blocking block 24 is away from the feed port 201. In the present application, nylon modified engineering plastic is used to prepare the guide block, and then the material is fed from the side of the processing box 2. After the feeding is completed, the controller immediately controls the cylinder 23 to extend to re-complete the blocking of the feed port 201. This can effectively reduce the probability of introducing new dust and impurities during the drying process of the modified plastic particles. In the initial state, the controller controls the servo motor 22 to work so that the blocking plate 21 is in a horizontal state. At this time, the modified plastic particles entering the processing box 2 will accumulate on the blocking plate 21, and then the controller controls the drive motor 31 and the heating plate 211 to work synchronously. The drive motor 31 can work to achieve The movement of the material turning rod 33, in combination with the heating plate 211, can realize the turning and drying process of the modified plastic particles on the sealing plate 21. After the modified plastic particles are dried, the material turning rod 33 moves to the upper side of the material turning shaft 32 so as not to hinder the subsequent rotation of the sealing plate 21. At this time, the servo motor 22 drives the sealing plate 21 to deflect, and then the plastic particles after drying can be transported to the feed hopper 11. Then the plastic particles are transported along the feeding auger 1 to the plastic injection molding equipment for injection molding of the guide block. When all the plastic particles are discharged, the sealing plate 21 moves back to the initial horizontal state, and then a new round of modified plastic particle drying and convenient transportation process can be started.
[0036] Compared with the existing technology, this device can realize convenient feeding into large-scale injection molding equipment without the need for climbing, reducing the risks in the feeding process. At the same time, it can realize the drying process of plastic particles to avoid subsequent pore defects caused by moisture in the plastic particles. The quality of the plastic particles after subsequent processing is improved, and the amount of dust and impurities entering during the drying process is effectively reduced.
[0037] In some embodiments, Figure 1 and Figure 2 As shown, the inside of the turning shaft 32 is hollow and one end is open, a plurality of through holes 34 are arranged on the circumference of the turning shaft 32, an air pump 35 is arranged on the processing box 2, a rotary joint 36 is connected to the open end of the turning shaft 32, the rotary joint 36 is connected to the air pump 35, and the air pump 35 is connected to a clean air source;
[0038] Further optimization of the above embodiment scheme, such as Figure 1As shown, a dust box 41, a plurality of circulation holes, a collection box 42 and a suction pump 43 are arranged on the top of the processing box 2. A plurality of suction holes are opened on the dust box 41. The suction holes correspond to the circulation holes one by one and are connected. The suction holes and the circulation holes are not shown in the figure. The dust box 41 is connected to the collection box 42 through a pipeline. The collection box 42 is connected to the suction pump 43 and a filter is arranged inside the collection box 42. The filter is not shown in the figure.
[0039] In this embodiment, after the plastic particles are dried, the air pump 35 starts working (at this time, the sealing plate 21 has not yet deflected and the heating plate 211 has stopped working), and the driving motor 31 starts working slowly at this time, and then the clean air source can be introduced into the turning shaft 32 and sprayed out from the plurality of through holes 34, and the dust and impurities in the plastic particles can be lifted up. It should be noted that the plastic particles lifted up during the blowing and turning process cannot pass through the flow holes, and the flow holes only allow dust and tiny impurities to pass through. The suction force of the suction pump 43 is controllable and will not cause the plastic particles to adhere to the top of the processing box 2 and block the flow holes. Then the suction pump 43 starts working to promptly draw dust and fine impurities out of the processing box 2 to the surface of the filter screen in the collecting box 42 for attachment, so that the plastic particles can be further cleaned to make the quality of the plastic particles better, and the air pump is connected to the clean air source to avoid the re-introduction of dust and other fine impurities.
