AI Technical Summary
The existing feeding device of the double roller mill causes the two ends of the roller ring to not participate in the work, resulting in uneven wear, which affects the material crushing effect and limits the adjustment of the roller ring distance, leading to premature replacement and waste of resources.
The structure includes a positioning plate, a sliding plate, an isosceles trapezoidal block, and a T-shaped threaded rod. The gap between the first and second rollers is adjusted by an automatic sensor, thus achieving automatic adjustment of the gap in the roller mill.
This achieves uniform roller wear, extends roller service life, improves material crushing uniformity, and reduces resource waste.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of crushing equipment, specifically, it relates to a pair of rollers for feeding. Background Technology
[0002] Double roller mills are widely used due to their simple structure and low operating costs. In operation, material enters the mill through a hopper and is clamped between two rollers. As the rollers rotate, the material is crushed and falls between them. The particle size of the output sand is related to the gap between the two rollers. However, the feeding device of existing double roller mills consists of an upper frame and baffles installed on the inner sides of the upper frame. The baffles are fixed to the upper frame, with only a small gap between them and the rollers. The working length of the double roller mill is approximately equal to the length of the rollers. Because the baffles are close to the edge of the rollers, the hopper extends into the feeding device, and the material falling from the hopper does not reach the ends of the rollers. This results in the ends of the rollers not participating in the operation, leading to uneven wear. After a period of operation, the ends of the rollers protrude, causing uneven material crushing. Furthermore, the contact between the protruding parts restricts the adjustment of the distance between the two rollers, forcing the rollers to be replaced before they reach their wear limit, thus failing to fully utilize their capacity.
[0003] To address these shortcomings, a feeding roller system is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a feeding roller.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A feeding roller includes two positioning plates, a first rotating roller rotatably engaged between the two positioning plates, a sliding plate and an isosceles trapezoidal block mounted on the upper side of the sliding plate slidably engaged on one side of each positioning plate, a T-shaped threaded rod rotatably engaged on the upper side of the isosceles trapezoidal block, one end of the T-shaped threaded rod being threaded into the interior of the positioning plate, and a second rotating roller rotatably engaged between the two sliding plates, the second rotating roller engaging with the first rotating roller.
[0007] Optionally, a first through hole is provided on one side of the positioning plate, the first rotating roller is rotatably engaged inside the first through hole, a first gear is mounted on the first rotating roller, a second gear is mounted on the second rotating roller, the second gear meshes with the first gear, a slide rail and two guide grooves connected to the slide rail are provided on one side of the positioning plate, and the sliding plate and the isosceles trapezoidal block are slidably engaged inside the slide rail.
[0008] Optionally, a guide rod is installed inside the guide groove to facilitate its installation. Sliding blocks are installed on both sides of the isosceles trapezoidal block to facilitate their installation. The sliding blocks are slidably fitted inside the guide groove. A guide hole is formed on one side of the sliding block, and the guide rod is located inside the guide hole. A spring is installed between the sidewall of the guide groove and one side of the sliding block to facilitate the sliding block's return to its original position under the spring's elasticity. The spring is sleeved around the guide rod to facilitate its return to its original position. A spring is sleeved around the guide rod. A second through hole is provided on one side of the sliding plate. The second roller is rotatably fitted inside the second through hole. A T-slot is provided on the upper side of the isosceles trapezoidal block. A T-shaped threaded rod is rotatably fitted inside the T-slot, which facilitates the rotation of the T-shaped threaded rod inside the isosceles trapezoidal block through the T-slot and improves the stability of the T-shaped threaded rod during rotation. A threaded hole is provided on one side of the positioning plate. The threaded hole is connected to the slide rail. One end of the T-shaped threaded rod is threaded inside the threaded hole, which facilitates the threaded rod being threaded inside the positioning plate through the threaded hole.
[0009] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0010] The sliding plate is designed so that the sliding block, under the action of the T-shaped threaded rod, drives the sliding plate to slide inside the slideway. This sliding plate drives the second roller to slide on one side of the first roller, thereby adjusting the gap between the first and second rollers. The gap size can then be adjusted by an automatic sensor, resulting in better plastic recognition.
