Description

Technical Field

[0001] The utility model belongs to the technical field of plastic product processing, and in particular relates to a plastic product processing feeding mechanism. Background Art

[0002] Plastic is a high molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. In the processing of plastic products, the plastic particles need to be transferred to the designated equipment through a feeding mechanism for processing.

[0003] In order to ensure that the plastic particles are not mixed with large-volume impurities, the existing feeding mechanism will add a filter screen to the feed hopper part to achieve filtering. For example, CN214454777U discloses a feeding mechanism for a foam stabilizer. This patent achieves filtering of the feeding material by adding a filtering structure, but does not disclose how to discharge the impurities after filtration. During long-term feeding, excessive impurities are likely to cause blockage of the filtering part, thereby affecting subsequent feeding. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The utility model aims to provide a feeding mechanism for processing plastic products, so as to solve the problem in the above background technology that the current feeding mechanism cannot quickly discharge the filtered impurities.

[0005] To achieve the above object, the utility model provides the following technical solution: a plastic product processing feeding mechanism, comprising a mounting seat, a feed hopper is installed on the top of the mounting seat, a filter mechanism is arranged in the feed hopper, and the filter mechanism comprises:

[0006] The filter screen is arranged in the feed hopper, and the two sides are sealed and fitted with the inner walls of the feed hopper to prevent the plastic raw materials from slipping out of the gap;

[0007] The adjusting component is arranged outside the two ends of the filter screen and fits with the two sides of the inner wall of the feed hopper to achieve sealing of the area; the adjusting component is composed of a sealing member and a rebound member, wherein the sealing member and the end faces of the two ends of the filter screen are in the same plane, and the rebound member is arranged at the bottom of the sealing member, and the two ends of the rebound member are respectively against the filter screen and the feed hopper.

[0008] Preferably, the middle part of the filter is raised and formed with a guide portion. When the plastic raw material is poured into the feed hopper, the guide portion can be used to roll the plastic raw material to achieve rapid filtration. The two ends of the filter extend obliquely toward the top of the feed hopper. This area can store filtered impurities. When the filter is taken out later, the impurities can be easily filtered.

[0009] Preferably, the sealing member is a sealing strip which is bonded to the outer walls at both ends of the filter screen and fits the inner wall of the feed hopper to achieve sealing. The sealing strip is made of elastic material and can be deformed to prevent the rebound member from swinging.

[0010] Preferably, placement holes are opened on the outer walls at both ends of the sealing strip, and the resilient member is a spring 1 placed in the placement hole, one end of the spring 1 abuts against the inner wall of the placement hole, and the other end abuts against the inner wall of the feed hopper.

[0011] Preferably, through holes are symmetrically opened on the outer sides of both ends of the feed hopper, and knocking columns are arranged inside the through holes. The end faces of the knocking columns extending to the outside of the feed hopper are formed with connecting plates, and a second spring is fixed between the connecting plate and the feed hopper.

[0012] Preferably, a transmission cylinder is also provided on the outside of one end of the feed hopper, and the transmission cylinder is connected to the feed hopper by a pipe. The plastic raw material in the feed hopper is injected into the transmission cylinder through the pipe, and a screw conveying shaft is provided in the transmission cylinder.

[0015] Through the designed filtering mechanism, large-volume impurities can be quickly filtered out and can also be quickly discharged, ensuring that the filtering area is not blocked and is always in a normal filtering state. At the same time, the filtering mechanism is simple to disassemble and assemble, convenient to process, and has high practicality as a whole. The setting of this filtering mechanism improves the shortcomings of the existing feeding mechanism in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a plastic product processing feeding mechanism, including a mounting seat 100, a feed hopper 101 is installed on the top of the mounting seat 100, and a filtering mechanism is arranged in the feed hopper 101, and the filtering mechanism includes:

[0025] The filter screen 200 is arranged in the feed hopper 101, and its two sides are sealed and fitted with the inner walls of the feed hopper 101 to prevent the plastic raw materials from slipping out of the gap;

[0026] The adjusting component is arranged outside the two ends of the filter 200 and fits with the two sides of the inner wall of the feed hopper 101, so as to achieve sealing of the area; the adjusting component is composed of a sealing member and a rebound member, wherein the sealing member and the end faces of the two ends of the filter 200 are in the same plane, and the rebound member is arranged at the bottom of the sealing member, and the two ends of the rebound member are respectively against the filter 200 and the feed hopper 101, and the filter 200 is driven to move left and right in the feed hopper 101 through the rebound member. Compared with the existing fixed filtering structure, this movable filtering structure can drive the plastic raw material to move, thereby improving the filtering efficiency.

[0027] In this embodiment, preferably, the middle portion of the filter screen 200 is raised and is formed with a guide portion 200a. When the plastic raw material is poured into the feed hopper 101, the guide portion 200a can be used to roll the plastic raw material to achieve rapid filtration. Both ends of the filter screen 200 extend obliquely toward the top of the feed hopper 101. This area can store filtered impurities. When the filter screen 200 is taken out later, the impurities can be easily filtered.

[0028] In this embodiment, preferably, the sealing member is a sealing strip 201, which is bonded to the outer walls at both ends of the filter screen 200, and the sealing strip 201 fits the inner wall of the feed hopper 101 to achieve sealing. At the same time, the sealing strip 201 is made of elastic material and can be deformed to prevent the rebound member from swinging.

[0029] In this embodiment, preferably, placement holes 200b are opened on the outer walls at both ends of the sealing strip 201, and the rebound member is a spring 202 placed in the placement hole 200b. One end of the spring 202 is against the inner wall of the placement hole 200b, and the other end is against the inner wall of the feed hopper 101. When the plastic raw material is poured in, the filter screen 200 will be vibrated, thereby squeezing the spring 202, and the rebound of the spring 202 is used to achieve a slight movement of the filter screen 200, thereby improving the filtration speed.

[0030] In the present embodiment, preferably, through holes 101a are symmetrically opened on the outer sides of both ends of the feed hopper 101, and a knocking column 300 is arranged inside the through hole 101a. The knocking column 300 extends to the end face of the feed hopper 101 in the outer direction to form a connecting plate 300a, and a spring 2 301 is fixed between the connecting plate 300a and the feed hopper 101. When the plastic raw material is partially accumulated on the side of the feed hopper 101, it will cause a slow feeding speed. At this time, by pulling the knocking column 300, the connecting plate 300a pulls the spring 2 301, so that the spring 2 301 rebounds, and then the end face of the knocking column 300 is quickly close to the inner end face of the through hole 101a, so as to knock on the feed hopper 101, thereby guiding the plastic raw material on the side to the middle position of the feed hopper 101.

[0031] In the present embodiment, preferably, a transmission cylinder 102 is further provided on the outside of one end of the feed hopper 101, and the transmission cylinder 102 is connected to the feed hopper 101 by a pipeline, and the plastic raw material in the feed hopper 101 is injected into the transmission cylinder 102 through the pipeline, and a screw conveying shaft is provided in the transmission cylinder 102, and the plastic raw material is transmitted to the discharge port at the top through the screw conveying shaft, so as to realize loading. Since the transmission cylinder 102 is an existing product, the specific loading and conveying principle will not be further described here.

[0032] In this embodiment, preferably, a roller is provided inside the bottom end of the mounting seat 100, which is not shown in the figure. The position of the mounting seat 100 is adjusted by the roller, and the longitudinal section of the mounting seat 100 is a right-angled trapezoid.

[0033] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
