Description

Technical Field

[0001] The utility model relates to the technical field of plastic film recycling equipment, and particularly relates to a cover shell with a bolt structure. Background Technique

[0002] Plastics of various categories are common materials in modern production and life, and used plastics can all be recycled and reused. The commonly used equipment is extrusion granulation equipment. Nowadays, more and more plastic products are used, and the demand for the recycling of waste plastics is increasing. Traditional extrusion machine cover shells are often integral cover shells, which are rigid in style and non-detachable, and are not convenient for later maintenance and transportation. Therefore, those skilled in the art provide a cover shell with a bolt structure to solve the problems raised in the above background technique. Summary of the Invention

[0003] The purpose of the utility model is to provide a cover shell with a bolt structure to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: It includes a bracket, an upper cover shell, a multi-gear adjustment hinge, a lower cover shell, a bracket fixing plate, a retaining ring and a strong magnet; the bracket includes several bracket modules, and adjacent bracket modules are connected by connecting pieces and fixed by bolts. At the upper part of the bracket, each bracket module is respectively installed with an upper cover shell through a multi-gear adjustment hinge. At the lower part of the bracket, at the corner positions of each bracket module, a bracket fixing plate is respectively fixed, a retaining ring is fixed on the bracket fixing plate, a strong magnet is fixed on the retaining ring, and the lower cover shell is adsorbed on the strong magnet.

[0005] Further, a movable support is installed inside the upper cover shell.

[0006] Further, the strong magnet is a circular perforated strong magnet.

[0007] After adopting the above structure, the beneficial effects produced by the utility model are: The cover shell with a bolt structure of the utility model is detachable, reducing the transportation volume. The upper cover shell can be opened by using the multi-gear adjustment hinge to observe the internal situation or perform maintenance. The lower cover shell is fixed by a strong magnet, which is convenient to remove for maintenance, saving operation time, improving efficiency, and having a beautiful appearance.

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0017] Refer to as Figure 1 —— Figure 6 As shown, the following technical solutions are adopted in this specific implementation mode: It includes a bracket 1, an upper cover shell 2, a multi-gear adjustment hinge 21, a lower cover shell 3, a bracket fixing plate 31, a retaining ring 32, and a strong magnet 33; the bracket 1 includes several bracket modules 11, and adjacent bracket modules 11 are connected by a connecting piece 12 and fixed by a bolt 13. The bolt 13 on the connecting piece 12 between adjacent bracket modules 11 can be removed, and the bracket 1 can be split into several bracket modules 11 for convenient transportation.

[0018] At the upper part of the bracket 1, each bracket module 11 is respectively installed with an upper cover shell 2 through a multi-gear adjustment hinge 21, and each upper cover shell 2 can be freely opened for easy observation of the internal situation or for maintenance.

[0019] At the lower part of the bracket 1, a bracket fixing plate 31 is respectively fixed at the corner positions of each bracket module 11. A retaining ring 32 is fixed on the bracket fixing plate 31, and a strong magnet 33 is fixed on the retaining ring 32. The lower cover shell 3 is adsorbed on the strong magnet 33. The strong magnet 33 is a circular strong magnet with holes. When maintenance is required, the lower cover shell 3 at the corresponding position can be directly removed. When the equipment is operating normally, the lower cover shell 3 is adsorbed on the bracket 1 by the strong magnet 33, which is very convenient to operate and improves the efficiency.

[0020] An active support is installed inside the upper cover housing 2. When the upper cover housing 2 is opened through the multi-gear adjustment hinge 21, the position of the upper cover housing 2 is fixed by fixing the active support to the positioning groove on the bracket 1, so that the upper cover housing 2 will not fall freely during maintenance, which is convenient for maintenance.

[0021] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
