Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the technical solutions of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: an adjustable-height cutting device, comprising a shaft 100, a cylinder 200, and blades 300. The overlapping method of the blades 300 is similar to that of ordinary scissors. Its working principle is that when the power pulls the strap through the cutting edge, the two blades roll, thereby separating the strap vertically at the cutting edge.

[0023] The shaft 100 is installed inside the cylinder 200, and its top end is integrally connected to the threaded rod 600. The shaft 100 not only supports the blade 300 and allows it to rotate, but also is located inside the cylinder 200, with its top end integrally connected to the threaded rod 600. An adjusting nut 400 is provided on the outside of the threaded rod 600, and a kit 500 is fixedly connected to the lower end of the adjusting nut 400.

[0024] The adjusting nut 400 is sleeved on the threaded rod 600, and its lower end is fixed to the connecting kit 500;

[0025] The blade 300 is raised or lowered by rotating the adjusting nut 400 to drive the kit 500 to move axially.

[0026] A locking nut 102 is provided at the bottom of the shaft 100 to lock the position after height adjustment. The height of the cylinder 200 and the blade 300 can be adjusted by loosening the lower locking nut 102 and then rotating the adjusting nut 400 at the top. After adjustment, the lower locking nut 102 is tightened again to fix the position.

[0027] In addition, the inner wall of the kit 500 is provided with a female thread that mates with the threaded rod 600.

[0028] In addition, a flat key 101 is provided on the outer side of the shaft 100, and a corresponding sliding groove is provided on the inner wall of the cylinder 200 to restrict the circumferential rotation of the shaft 100.

[0029] The top of the cylinder 200 is provided with a nut A700, and below it is a sleeve 800; when the nut A700 is tightened, the sleeve 800 is pressed down to fix the blade 300.

[0030] A compression spring 103 is provided on one side of the blade 300 to provide additional protection for the blade 300.

[0031] The sleeve 800 is located below the nut A700 and is used to engage with the nut A to lock and press down to fix the blade 300.

[0032] The purpose of the cylinder 200 is to house the blade 300.

[0033] The adjusting nut 400 engages with the threaded rod 600, and the height of the blade 300 is adjusted by rotating the adjusting nut 400.

[0034] The kit 500 is fitted onto the outside of the threaded rod 600 of the shaft 100.

[0035] Working principle:

[0036] Step 1: Initial State Preparation

[0037] The device is in the locked state: the bottom locking nut 102 is tightened, and the height of the blade 300 is fixed; the top nut A700 presses against the sleeve 800 to prevent the blade 300 from moving axially.

[0038] Step 2: Release the height lock

[0039] Loosen the bottom locking nut 102 to release the axial fixation of the shaft 100;

[0040] At the same time, loosen the top nut A700 to release the downward pressure of the sleeve 800 on the blade 300.

[0041] Step 3: Adjust the blade height

[0042] Rotating the adjusting nut 400, through the threaded engagement between the kit 500 and the threaded rod 600, drives the fixedly connected kit 500 to move axially;

[0043] The blade 300 moves up and down along the shaft 100. At this time, the flat key 101 engages with the groove of the cylinder 200 to prevent the shaft 100 from rotating.

[0044] The compression spring 103 is compressed or released to provide cushioning and maintain the contact pressure between the blade 300 and the cylinder 200.

[0045] Step 4: Lock the target height

[0046] After the blade 300 reaches the target position, tighten the bottom locking nut 102 to press against the lower end face of the cylinder 200 and fix the position of the shaft 100.

[0047] Tighten the top nut A700, drive the sleeve 800 to press down, and fix the blade 300 to prevent it from loosening.

[0048] Step 5: Anti-loosening verification

[0049] Tap the blade 300 lightly to confirm there is no axial displacement;

[0050] Observe whether the compression spring 103 is in a pre-compressed state to provide continuous redundant preload.

[0051] In summary, this study aims to develop an innovative design for automated suppository manufacturing equipment, with the primary objective of improving the automation level and cutting precision of the suppository production line. By introducing a cutting device with height adjustment capabilities, this design achieves precise control of the cutting position, ensuring the smoothness of the suppository edges and meeting stringent product quality standards. Furthermore, this automated design reduces the need for manual operation, thereby improving production efficiency and enhancing the safety of the production process.

[0052] Later, as needed, the cylinder can be adjusted to achieve a 200° follow-up adjustment effect, further improving the synchronization and ease of operation of blade height adjustment.
