AI Technical Summary
The lack of effective alignment tools during the installation or maintenance of the pill-making rollers in traditional Chinese medicine pill-making machines necessitates repeated machine start-ups and shutdowns for verification, which disrupts the production rhythm.
An adjustment and alignment tool was designed, comprising a horizontal crossbar, an arc-shaped hollow cylinder, and a telescopic rod. The tool achieves rapid alignment by meshing the arc-shaped plate with the teeth of the shot-rolling roller, simplifying the operation process.
It enables rapid alignment of the shot rolling rollers, simplifies the operation steps, improves production efficiency, and avoids the tedious process of repeatedly turning the machine on and off for verification.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine pill-making equipment technology, and in particular to a pill-making machine roller adjustment and alignment tool. Background Technology
[0002] Various problems can occur during the use of traditional Chinese medicine pill-making machines, among which incomplete pill formation and twisted material are common issues. The final pill-making mechanism of a traditional Chinese medicine pill-making machine relies on the axial vibration of two gear-like pill-rolling rollers to achieve the pill-making operation. The structure of the pill-rolling rollers is as follows... Figure 1 As shown, the pellet rolling rollers are securely pressed onto the output shaft of the pellet rolling machine by a central clamping screw. If the teeth of the two rollers are not aligned, the pellet strips will appear twisted. Currently, the process lacks effective alignment methods during roller installation and maintenance. Operators can only visually align them, then test the machine, repeating this process several times until the two rollers are aligned. However, this process requires repeated start-ups and verifications, which is cumbersome and disrupts production.
[0003] To address the aforementioned issues, a roller adjustment and alignment tool for pelletizing machines is proposed. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a roller adjustment and alignment tool for a pelletizing machine, which effectively solves the problem that there is no alignment tool for the two pelletizing rollers during installation or maintenance in the prior art.
[0005] The technical solution includes a horizontal crossbar with an arc-shaped hollow cylinder opening downwards on the lower side of the crossbar. The hollow cylinder and the crossbar are connected by multiple telescopic rods. A partition is fixed in the middle of the hollow cylinder cavity. There are arc-shaped plates at both ends of the hollow cylinder. The arc-shaped plates can slide along the hollow cylinder. A compression spring is connected between one end of the arc-shaped plate and the partition. The other end of the arc-shaped plate extends out of the hollow cylinder. Teeth are provided on the outer circular surface of the arc-shaped plate.
[0006] Preferably, the telescopic rod includes a vertical cylinder, the upper end of which is fixed to a horizontal bar, and a rod that can move up and down is inserted inside the cylinder. A tension spring is installed between the upper end of the rod and the cylinder, and the lower end of the rod is fixed to an arc-shaped plate.
[0007] Preferably, the lower end of the insertion rod is fixed to the front end face of the hollow cylinder, and the insertion rod is L-shaped.
[0008] This utility model has an ingenious structure. This tool can be used to align shot rolling rollers of different specifications without the need for repeated verification and start-up. It is simple and quick to operate, which helps to improve production efficiency. Attached Figure Description

[0012] Figure 4 This is a structural schematic diagram of the hollow cylinder, partition, arc plate, and compression spring in this utility model. Detailed Implementation
[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0014] Depend on Figures 1 to 4 The present invention includes a horizontal crossbar 1, with an arc-shaped hollow cylinder 2 opening downwards on the lower side of the crossbar 1. The hollow cylinder 2 and the crossbar 1 are connected together by multiple telescopic rods 3. A partition 4 is fixed in the middle of the cavity of the hollow cylinder 2. There are arc-shaped plates 5 at both ends inside the hollow cylinder 2. The arc-shaped plates 5 can slide along the hollow cylinder 2. A compression spring is connected between one end of the arc-shaped plate 5 and the partition 4. The other end of the arc-shaped plate 5 extends out of the outer side of the hollow cylinder 2. Teeth are provided on the outer circular surface of the arc-shaped plate 5.
[0015] The telescopic rod 3 includes a vertical cylinder, the upper end of which is fixed to the horizontal bar 1. A rod that can move up and down is inserted into the cylinder. A tension spring is installed between the upper end of the rod and the cylinder. The lower end of the rod is fixed to the arc plate 5.
[0016] To avoid interference between the crossbar 1 and the hollow cylinder 2 during use, the lower end of the insertion rod is fixed to the front end face of the hollow cylinder 2, and the insertion rod is L-shaped.
[0017] It is worth noting that in this solution, the crossbar 1 is placed on the clamping bolt at the center of the two shot rolling rollers during use, and the telescopic rod 3 pulls the hollow cylinder 2 upward and makes the teeth on the upper surface of the two arc plates 5 mesh with the shot rolling rollers, thereby aligning the teeth on the two shot rolling rollers and ensuring the quality of the shot.
[0018] When using, such as Figure 1 , 2 As shown, the crossbar 1 is horizontally placed at the end of the clamping bolt in the center of the shot rubbing roller, and the hollow cylinder 2 is placed below the two shot rubbing rollers. At this time, the tension spring inside the cylinder provides a vertical upward tension to the hollow cylinder 2, and the tooth structure at the upper end of the arc plate 5 also meshes with the shot rubbing roller. At this time, the two compression springs inside the hollow cylinder 2 cause the extension and contraction of the two arc plates 5 to be consistent, which in turn ensures that the hollow cylinder 2 can be kept directly below the middle of the two shot rubbing rollers, thus ensuring that the teeth of the two shot rubbing rollers can be aligned.
[0019] In practical application, this invention requires only two steps: First, place the horizontal bar 1 horizontally on the two clamping bolts; second, pull the hollow cylinder 2 downwards until it is directly below the line connecting the central axes of the two shot-rolling rollers, and then release. The remaining balance is achieved by the tension spring inside the cylinder and the compression spring inside the hollow cylinder 2. At this point, simply tighten the clamping screws. Note that when tightening the clamping screws, hold the horizontal bar 1 still with one hand, and use an Allen wrench with the other hand to tighten the clamping screws.
[0020] This utility model has an ingenious structure. This tool can be used to align shot rolling rollers of different specifications without the need for repeated verification and start-up. It is simple and quick to operate, which helps to improve production efficiency.
