Description

Technical Field

[0001] The utility model relates to the technical field of nut production, in particular to a production and cleaning device for press nuts. Background Art

[0002] Push nuts, also known as squeeze nuts, are a type of fastener that is primarily used to secure two or more parts together. They work by inserting the nut into a pre-designed hole and then squeezing it into place using pressure. Once the nut is squeezed into place, it forms a strong connection that keeps the parts fixed. During the production process of push nuts, some iron filings or oil stains generated during processing are likely to remain on the push nuts, so cleaning equipment is required to clean the push nuts.

[0003] As disclosed in a Chinese patent: a cleaning device for nut production, application number: CN202020663950.3, the outer steel ring and the inner steel ring form a ball bearing, the inner steel ring is driven to rotate by a motor, a circle of annular grooves is opened on the upper side of the inner steel ring, a cross-shaped boss is arranged in the center of the inner steel ring, the cylinder is fixed on the outer steel ring, and a number of centrally symmetrical support joints are arranged at the upper end of the cylinder; a roller is also arranged on the inner steel ring, the lower end of the roller is clamped on the inner steel ring, and the upper part thereof is in contact with the support joint, and the beneficial effect is: a groove is arranged on the base for cooperating with the boss and the groove, so that the roller can be firmly mounted on the inner steel ring, and the ball head at the front end of the support joint is clamped in the arc-shaped groove, which can prevent the roller from shaking when the inner steel ring rotates, and the residue in the nut will be thrown out through the mesh and deposited at the bottom of the cylinder, and the residue can be brought out when the cleaning liquid is discharged from the liquid outlet.

[0004] However, in the above technical scheme, the current nut cleaning equipment is roughly divided into two types: microwave cleaning and drum cleaning. In drum cleaning, the stains on the nuts will be thrown out through the mesh, some of these stains will settle at the bottom of the equipment, and some will enter the cleaning liquid, which will cause a large number of stains mixed in the cleaning liquid. These stains can easily adhere to the nuts again with the flow of the cleaning liquid, thereby causing secondary pollution to the cleaned nuts. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The main purpose of the utility model is to provide a press nut production cleaning equipment, which can effectively solve the problem that the current nut cleaning equipment in the background technology is roughly divided into two types: microwave cleaning and drum cleaning. During drum cleaning, the stains on the nuts will be thrown out through the mesh, and some of these stains will settle at the bottom of the equipment, and some will enter the cleaning liquid, which will cause a large number of stains mixed in the cleaning liquid. These stains can easily adhere to the nuts again with the flow of the cleaning liquid, thereby causing secondary contamination of the cleaned nuts.

[0025] The second rotating column 802 is provided with a second sprocket 806 and a cam 807. The driving mechanism 8 is slidably provided with a rack 808 in the equipment body 1. A hydraulic rod 809 is fixedly provided on the outer wall of one side of the rack 808. When it is necessary to collect and filter the cleaning liquid in the cleaning tank 2, the hydraulic rod 809 is first started, and the rack 808 is moved by the hydraulic rod 809. The rack 808 drives the gear 805 to rotate, and the gear 805 drives the first rotating column 801 to rotate. The first rotating column 801 drives the first sprocket 803 to rotate.
