Abstract
Description
Technical Field
[0001] This utility model relates to the field of plaster preparation technology, specifically a slitting device for plaster preparation. Background Technology
[0002] A medicated plaster is a topical preparation applied to specific areas of the body. It allows the medication to penetrate the body through the skin, exerting a local or systemic therapeutic effect. It consists of a backing material, a layer of medicated plaster, and an anti-adhesive layer.
[0003] A search revealed a Chinese patent with publication number CN209812435U that discloses a slitting device for the production of medicated plasters. The device adjusts the width of the medicated plasters without removing the blades by adjusting the shaft. At the same time, a cold air blower can blow cold air through the roller axis to the circular cutter, thereby reducing the temperature of the circular cutter and preventing the plasters from sticking to the cutter, thus increasing the slitting success rate.
[0004] However, in the existing technology, different plaster materials have different requirements for the cutting device. The cutting device cannot adapt well to the cutting of various materials, which leads to the need to change the blade or adjust the equipment, resulting in wasted time. In order to solve the problem that the cutting device in the existing technology cannot adapt well to the cutting of various materials, this application proposes to improve the applicability of the device and increase work efficiency by using an auxiliary cutting component. Utility Model Content
[0005] The existing technology has shortcomings and defects in the aforementioned background technology, namely that the slitting device cannot adapt well to the slitting of various materials.
[0006] The present invention discloses a slitting device for preparing plaster patches, comprising a mounting frame, two rotating shafts on the mounting frame, a transmission assembly between the two rotating shafts, a slitting blade one and a slitting blade two on the two rotating shafts respectively, and a connecting assembly between the slitting blade one and the slitting blade two.
[0007] Furthermore, the connecting assembly includes a sleeve, which is disposed on the rotating shaft. A limit strip is provided on the rotating shaft, and a sliding groove is provided on the inner side of the sleeve. The limit strip is slidably disposed with the sliding groove. The first slitting blade and the second slitting blade are mounted on corresponding sleeves, and the sleeves on the two rotating shafts are connected by a connecting plate.
[0008] Furthermore, a bidirectional threaded rod is provided between the connecting plate and the mounting bracket. The bidirectional threaded rod is rotatably mounted on the mounting bracket. The two ends of the bidirectional threaded rod are threadedly connected to the connecting plates at both ends and are slidably disposed with the connecting plate at the middle. An equidistant component is provided between the connecting plates.
[0009] Furthermore, the equidistant component includes a fixed shaft one, which is mounted on the connecting plate. Two scissor blades are rotatably mounted on the fixed shaft one, and the ends of the scissor blades on two adjacent connecting plates are rotatably connected by a fixed shaft two.
[0010] Furthermore, a spring is provided between two adjacent connecting plates, and the two ends of the spring are respectively fixedly connected to the corresponding connecting plate.
[0011] Furthermore, each of the two shafts is equipped with a sprocket, and the two sprockets are connected by a chain.
[0012] Furthermore, the two rotating shafts are arranged in parallel and on the same horizontal plane, and the connecting plate is set in an "H" shape.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model is equipped with a rotating shaft, a first slitting blade, and a second slitting blade. During operation, the two rotating shafts are driven to rotate synchronously, and the corresponding first and second slitting blades rotate accordingly. The first slitting blade initially divides the plaster while keeping it connected. Then, the second slitting blade further divides the plaster at a uniform position, thus achieving complete division and avoiding incomplete division in one step. This allows for the cutting of various materials, increasing the applicability of the device and eliminating the need for blade replacement, thereby improving work efficiency.
[0015] 2. This utility model, by setting up components such as a fixed shaft one, a fixed shaft two, a bidirectional threaded rod, and a scissor plate, connects the two slitting blades one and two rotating shafts through the cooperation between the connecting plate component and the sleeve component during operation. The bidirectional threaded rod component drives the connecting plates at both ends to move relative to each other. At the same time, the cooperation between the scissor plate component, the fixed shaft one component, and the fixed shaft two component drives the adjacent connecting plates to move accordingly, thereby realizing the equidistant adjustment of multiple connecting plates and indirectly adjusting the position of slitting blade one and slitting blade two, increasing the applicability of the device.

A slitting blade 3 and a slitting blade 4 are respectively mounted on the two rotating shafts 2, and a connecting assembly is provided between the slitting blade 3 and the slitting blade 4. The size of the slitting blade 3 is smaller than the size of the slitting blade 4.
[0024] Combination Figure 1 , Figure 3 As shown, the connecting assembly includes a sleeve 5, which is mounted on a rotating shaft 2. A limit strip 7 is provided on the rotating shaft 2, and a sliding groove 8 is provided on the inner side of the sleeve 5. The limit strip 7 and the sliding groove 8 are slidably disposed. The first slitting blade 3 and the second slitting blade 4 are mounted on the corresponding sleeves 5. The sleeves 5 on the two rotating shafts 2 are connected by a connecting plate 6. When the rotating shaft 2 rotates, the sleeves 5 are driven to rotate through the limit strip 7. The sleeves 5 drive the corresponding first slitting blade 3 and second slitting blade 4 to rotate.
[0025] See Figure 2 As shown, a bidirectional threaded rod 9 is provided between the connecting plate 6 and the mounting bracket 1. The bidirectional threaded rod 9 is rotatably mounted on the mounting bracket 1. The two ends of the bidirectional threaded rod 9 are threadedly connected to the connecting plates 6 at both ends and slidably disposed with the connecting plate 6 at the middle. An equidistant component is provided between the connecting plates 6. The bidirectional threaded rod 9 is driven to rotate by a servo motor. The bidirectional threaded rod 9 drives the connecting plates 6 at both ends to move relative to each other. While the connecting plates 6 are moving, the equidistant component drives the connecting plate 6 at the middle to move. The connecting plates 6 drive the sleeve 5 to move. The sleeve 5 drives the first slitting blade 3 and the second slitting blade 4 to move, thereby realizing the adjustment of the position of the second slitting blade 4 and the first slitting blade 3.
[0026] In this embodiment, the equidistant component includes a fixed shaft 12, which is mounted on the connecting plate 6. Two scissor plates 11 are rotatably mounted on the fixed shaft 12. The ends of the scissor plates 11 on two adjacent connecting plates 6 are rotatably connected by a fixed shaft 2 13. When the connecting plates 6 at both ends move, the fixed shaft 12, the fixed shaft 2 13 and the scissor plates 11 cooperate with each other, so that the adjacent connecting plates 6 move together and maintain the equidistant arrangement between the connecting plates 6.
[0027] In this embodiment, a spring 10 is provided between two adjacent connecting plates 6. The two ends of the spring 10 are fixedly connected to the corresponding connecting plates 6. A sprocket 14 is provided on each of the two rotating shafts 2. The two sprockets 14 are connected by a chain 15. The rotating shaft 2 is driven to rotate by a servo motor. The rotating shaft 2 drives the sprocket 14 to rotate. The sprocket 14 drives the chain 15 to rotate. The chain 15 drives the other sprocket 14 to rotate. At the same time, the sprocket 14 drives the corresponding rotating shaft 2 to rotate, thereby realizing the synchronous rotation of the two rotating shafts 2.
[0028] Combination Figure 1 , Figure 2 As shown, the two rotating shafts 2 are arranged in parallel and on the same horizontal plane. The connecting plate 6 is set in an "H" shape to improve the connection stability between the two sleeves 5.
[0029] The implementation principle is as follows: First, the device is installed on the designated equipment through the mounting bracket 1. The rotating shaft 2 is driven to rotate by the servo motor. The rotating shaft 2 drives the sprocket 14 to rotate. The two rotating shafts 2 rotate synchronously through the cooperation between the chain 15 and the sprocket 14. The two rotating shafts 2 drive the corresponding cutting blades 3 and 4 to rotate. First, the sprocket 3 performs preliminary cutting of the plaster, while the plasters remain connected. Then, the cutting blade 4 performs secondary cutting along the position of the cutting blade 3. Through multiple gradual cuttings, incomplete cutting of the plaster is avoided, achieving the cutting of various materials.
