Description

Technical Field

[0001] The utility model belongs to the technical field of plaster production, and in particular relates to an automatic production device for plaster patches. Background Art

[0002] In the field of plaster processing, traditional manual processing is still the main method used by many small-scale processing sites, including manual application of drugs on patches, manual plastic sealing and other steps. This method is inefficient, has high labor costs, and unstable processing quality. Some small and medium-sized factories still use simple mechanical equipment, such as simple cutting machines, dropper machines, packaging machines, etc. These equipment are slightly more efficient than manual processing, but have a low degree of automation, low precision and efficiency, and poor quality control capabilities, which may lead to uneven processing results. Some large plaster processing plants use modern equipment, such as fully automated plaster machines, which can improve processing efficiency and precision, but the investment and maintenance costs are high, the technical requirements are complex, and professional maintenance is required. Therefore, it is not widely used in most plaster processing plants. In the production process of various traditional plasters, there is a step of extruding and encapsulating drugs. When the machine squeezes the drug downward, there is uncertainty in the direction and range of drug extension. If the drug's extension range is too large, when patients use plaster patches to stick to joints or skin, the drug may overflow due to joint movement or skin squeezing; if the drug range is too small, the adhesive will stick to the skin too much, and the drug will be unevenly squeezed together, which is not conducive to the good effect of the drug. Therefore, the plaster processing market urgently needs to introduce a low-cost, high-quality plaster patch automatic production device to reduce the defective rate of plaster patch production, enhance the reliability of plaster patch production by enterprises, and improve the comfort of patients using plaster patches.

DETAILED DESCRIPTION

[0025] The implementation scheme of the utility model will be described in detail below in conjunction with examples. The following examples are only used to illustrate the utility model and should not be regarded as limiting the scope of the utility model.

[0026] Example 1

[0027] An automated production device for plaster patches comprises a conveyor belt 15, above which are arranged a suction cup 1, a drug outlet 6, a roller 8, a conveying rod 9, a shearing knife 10, an extrusion platform 11, and a camera 13 from left to right; the suction cup 1 is mounted on a slide rail 2, the slide rail 2 is fixed below a cantilever 4, and a stepping motor 3 is mounted on the side of the cantilever 4; the drug outlet 6 is connected to a drug reservoir 7 via a control valve 5, and the drug reservoir 7 is connected to a drug liquid pump 20 via a hose 19; the roller 8 and the conveying rod 9 are fixed on a base 18 on one side of the conveyor belt 15; two outer ears 17 are symmetrically mounted on the side of the extrusion platform 11, and the outer ears 17 are engaged with a sleeve 16; the camera 13 is fixed to the top of an L-shaped bracket 21, a cylinder 12 is arranged on the side of the L-shaped bracket 21, and a push plate 14 is mounted in front of the cylinder 12.

[0028] The conveying rod 9 is located at the lower right side of the roller 8 .

[0029] The height of the sleeve 16 is higher than the extrusion platform 11 .

[0030] The bottom of the push plate 14 is higher than the horizontal plane of the conveyor belt 15, and the raised portion is smaller than the thickness of the plaster patch.

[0031] Example 2

[0032] The implementation process of this device is as follows:

[0033] Step 1: The stepper motor 3 drives the suction cup 1 to move along the slide rail 2 to the left side of the cantilever 4, and the suction cup 1 adsorbs a single patch, and the patch moves to the right side of the cantilever 4 with the suction cup, and then the suction cup 1 stops adsorbing and places the patch on the conveyor belt 15;

[0034] Step 2: The patch is transported to the bottom of the drug outlet 6, and the drug liquid pump 20 transports the drug to the drug storage container 7 through the hose 19. The control valve 5 is opened, and the drug flows out from the drug outlet 6 and drips on the center of the patch, completing the spraying of the plaster patch;

[0035] Step 3: The patch is transported to the patch packaging mechanism, and the conveying rod 9 rotates clockwise to unfold the transparent tape wrapped on the roller 8; when the transparent tape is completely attached to the patch surface, the shear knife 10 falls and cuts the transparent tape; then, the extrusion platform 11 drives the sleeve 16 to move downward, and the bottom of the sleeve 16 first contacts the patch to form an encirclement, and the extrusion platform 11 continues to move downward, contacts the transparent tape above the drug, and applies downward pressure to evenly squeeze the transparent tape and the drug onto the patch surface, completing the plaster patch packaging;

[0036] Step 4: The patch is transported to the drug testing agency, and the camera 13 collects the image of the plaster patch, identifies the area covered by the drug, and determines whether it is within the target area. Figure 7 As shown, the shaded part indicates the allowable range of the drug boundary. If the drug boundary coverage range is not within the target area, it is a product of unqualified quality. The cylinder 12 drives the push plate 14 to push it out from the side of the conveyor belt 15. On the contrary, if it is a product of qualified quality, the cylinder does not move, and the plaster patch enters the subsequent process. Then repeat Step 1, Step 2, and Step 3 to complete the automated production and testing of the next plaster patch.
