Description

Technical Field

[0002] Gel patch is an external preparation, which is a gel patch with a paste evenly coated on a backing and covered with a thin film on the surface of the paste. The gel patch has the advantages of large drug loading, promoting transdermal drug penetration, no allergic reaction and irritation to the skin, no pulling pain when peeling off and no residue. The production of gel patch is usually carried out by a compression molding machine, and the compression molding machine for preparing gel patch is basically composed of a base, a plaster cloth placement and sensing system, a drip system, a molding system, a pneumatic system, a control system and a display interface, a transmission and execution system, a punching system and auxiliary equipment. Among them, the plaster cloth is divided into two parts, one is the plaster base cloth used to carry the plaster, and the other is a protective film used to cover and protect the plaster. The protective film is generally made of polyethylene film.

[0003] At present, the punching technology used in the existing molding machines is mainly roller cutting. When cutting the patch, the cutting specifications are fixed and cannot be applied to the production of patches of different specifications. The applicability is poor. Since the patch contains adhesive, the colloid will inevitably adhere to the punching tool when cutting it. As the equipment continues to run, the colloid adhered to the tool continues to accumulate, which is easy to affect the cutting effect of subsequent patches and reduce the qualified rate of product production. In addition, when the equipment is producing gel patches, the operation of each part is basically controlled by a separate drive. The configuration of a large number of drive structures makes the production cost of the equipment high. Summary of the invention

The half gear 52 and the gear 62 are meshed and transmitted, and the sleeve cap 53 and the movable rod 3441 are linked through a toothed chain member 54. The toothed chain member 54 is composed of two sprockets and a chain. The two sprockets are respectively assembled on the rotating shaft and the movable rod 3441. The two sprockets are connected by a chain, and then the movable rod 3441 is synchronously driven to rotate during the movement of the rotating shaft.

[0062] See also Fig.13 In the embodiment of the present invention, the material distributing mechanism 4 is composed of a conveying assembly 41, a side plate 42, an inverted L-shaped plate 43 and a fan body 44. The conveying assembly 41 is composed of a material transfer roller, a conveyor belt and a frame. There are two frames, which are symmetrically arranged on the top of the base 1, and there are two material transfer rollers, which are respectively arranged between the two frames. The material transfer rollers are located at both ends of the frame, and the two material transfer rollers are connected by a conveyor belt. The conveying assembly 41 is located below the guide hopper 32, and the finished patch falls onto the conveying assembly 41 by itself through the guide hopper 32.

[0063] The side plate 42 is fixedly connected to the front frame of the conveying assembly 41 by bolts, and the side plate 42 is set to prevent the finished patch from falling out of the conveying assembly 41 when it is dropped. The inverted L-shaped plate 43 is fixedly connected to the rear frame of the conveying assembly 41 by bolts. A rectangular through groove is provided on the top shell wall of the inverted L-shaped plate 43, and the fan body 44 is loaded in the rectangular through groove to accelerate the cooling speed of the finished patch on the conveying assembly 41. The setting of the fan body 44 realizes the blowing of the conveying assembly 41, and then the finished patch on the conveying assembly 41 can be quickly cooled.

[0064] The transmission mechanism 7 includes a coupling 71 installed on the front end of the driving roller 61. A transmission shaft 72 is provided at the output end of the coupling 71, and the transmission shaft 72 is connected to the corresponding material transfer roller through a pulley set 73. The pulley set 73 is composed of two pulleys and a belt. The two pulleys are respectively mounted on the transmission shaft 72 and the corresponding material transfer roller. The two pulleys are connected by a belt. When the driving roller 61 moves, the transmission mechanism 7 synchronously drives the conveying assembly 41 to operate, so as to complete the conveying and displacement of the finished plaster falling thereon.

[0065] The fixing plate 21 and the paving plate 31 are connected to the inverted L-shaped plate 43 via columns, so as to ensure the stability of the arrangement of the die component 2 and the cutting component 3.

[0066] The working principle of the present invention is: when the equipment is used, it is necessary to first adjust the trimming mechanism 33 in the cutting component 3 according to the width specification of the plaster cloth, so that it can reasonably grind and trim the plaster cloth currently in circulation. Hold the cylinder 333 with one hand, and adjust the adjusting screw 332 in the trimming mechanism 33 with the other hand, thereby driving the inner ring to move, so that the rolling wheel 335 loaded thereon is displaced and adjusted, so that the rolling wheel 335 is adjusted to a suitable position. Then the plaster cloth is passed through, and the plaster base cloth that has completed the ointment blanking contacts the protective film, and after the plaster cloth is formed, it enters the die component 2 and the cutting component 3 in turn, and then the edge material is blanked under the action of the traction member 6.

[0067] When the plaster cloth is feeding, the rolling wheel 335 ensures that the protective film used to cover the plaster in the plaster cloth is attached to the plaster base cloth. The cutting ring 336 located on the rolling wheel 335 simultaneously cuts off the excess part of the plaster cloth during the feeding process of the plaster cloth, and the cut plaster cloth enters the waste box 9 for collection and processing under the action of the driving roller 61 in the traction member 6.

[0068] The motor 51 in the driving mechanism 5 is turned on by an external controller, and the rotating shaft drives the half gear 52 to move. The half gear 52 meshes with the gear 62 in the traction member 6 for transmission, thereby realizing the rotation of the driving roller 61 in the traction member 6, thereby driving the plaster cloth to feed.

[0069] Due to the meshing teeth number between the half gear 52 and the gear 62, the half gear 52 is meshed with the gear 62 in the first half circle under the drive of the motor 51, thereby driving the driving roller 61 to move, so as to realize the feeding movement of the plaster cloth for one unit. When driven by the motor 51, it not only drives the half gear 52 to move, but also drives the sleeve cap 53 to move synchronously. Then, in the motion state of the first half circle, the sleeve cap 53 drives the movable rod 3441 in the driving assembly 344 of the punching mechanism 34 in the cutting component 3 to rotate synchronously through the effect of the transmission of the toothed chain member 54. During the rotation of the movable rod 3441, the displacement seat 3444 sleeved thereon drives the push plate 3442 to move, thereby adjusting the elastic telescopic rod 3443 movably connected to the mileage operation to the inflection point of the mileage groove. At this time, the elastic telescopic rod 3443 is in active contact with the embedded groove in the mileage groove.

[0070] When the rotating shaft drives the half gear 52 to complete a half-circle rotation, the half gear 52 is disengaged from the gear 62 when the rotating shaft drives the half gear 52 to move continuously. At this time, the traction member 6 stops moving, and the plaster stops feeding. At this time, the movement state of the rotating shaft, through the cooperation of the sleeve cap 53 and the toothed chain member 54, synchronously drives the movable rod 3441 to move continuously. During the rotation process of the movable rod 3441, the displacement seat 3444 sleeved thereon drives the push plate 3442 to reset and move. At this time, since the elastic telescopic rod 3443 is in active contact in the embedded groove of the mileage groove, the elastic telescopic rod 3443 moves downward under the condition of the push plate 3442.

[0071] When the elastic telescopic rod 3443 moves downward for adjustment, it synchronously drives the lifting assembly 342 of the punching mechanism 34 in the cutting component 3 to move. The bending plate 3421 in the lifting assembly 342 moves downward synchronously on the carrier 341 along with the elastic telescopic rod 3443. During the downward movement of the bending plate 3421, the return spring 2 on the guide rod 3423 is squeezed. When the bending plate 3421 moves downward, not only the cutting assembly 343 in the punching mechanism 34 moves synchronously, but also the joint plate 25 in the die component 2 moves downward synchronously through the connecting arm 8.

[0072] During the downward movement of the cutting assembly 343, the cutting assembly 343 moves downward as a whole along with the bending plate 3421, and the cleaning member 3436 arranged thereon drives the main rod 34361 to move under the pulling action of the traction rope, thereby stretching the spring telescopic rod 2 34365. When the main rod 34361 moves, the multiple assembly seats 34362 arranged thereon move synchronously, and then the spring telescopic rod 1 34363 drives each scraper 34364 to adjust, thereby scraping and cleaning the tool body 3435.

[0073] When the cutting assembly 343 moves downward, the bottom of the frame 3432 first contacts the plaster cloth on the paving board 31. After the frame 3432 contacts the plaster cloth, the tool body 3435 in the cutting assembly 343 continues to move downward, compressing the telescopic rod 3433. When the tool body 3435 cuts the plaster cloth, the frame 3432 ensures the stability of the plaster cloth in its position, thereby ensuring the pass rate of the plaster cloth cut into plasters. After cutting, the finished plaster slides onto the transmission mechanism 7 through the guide hopper 32.

[0074] When the joint plate 25 in the die component 2 is forced to move downward, it drives the adjusting rod 24 to move, compresses the reset spring 1, and then drives the die body 27 to move downward through the carrier plate 26, thereby realizing the compression molding of the ointment at the current position on the plaster cloth.

[0075] When the push plate 3442 is reset to the maximum mileage, the tool body 3435 completes the punching of the plaster cloth. At this time, the elastic telescopic rod 3443 located in the mileage groove on the push plate 3442 moves upward along the vertical part of the mileage groove under the action of the reset spring 1 and the reset spring 2, driving the bending plate 3421 to move upward synchronously. Then, the die component and the cutting assembly 343 are driven to reset. In the process of the cleaning member 3436 in the cutting assembly 343, the traction rope lacks pulling force during its reset activity, and then the cleaning member 3436 is synchronously reset with the cooperation of the spring telescopic rod 2 34365, so as to scrape and clean the tool body 3435 again.

[0076] After the motor 51 drives the rotating shaft to complete one cycle, it continues to move, and at this time, the half gear 52 is meshed with the gear 62 on the traction member 6 again for transmission, and the above steps are repeated again and again to achieve the production of the finished product.

[0077] The driving roller 61 not only realizes the feeding of the plaster cloth during the rotation process, but also drives the intermittent operation of the conveying assembly 41 in the cloth mechanism 4 synchronously through the transmission mechanism 7. The conveying assembly 41 realizes the displacement adjustment of the finished plaster falling on it during the movement process, which not only leaves space for the subsequent finished plaster to flow out, but also the finished plaster will pass through the cooling area of ​​the fan body 44 during the restraint process on the conveying assembly 41. In this way, the cooling efficiency of the finished plaster is accelerated, which is convenient for the subsequent storage and processing.

[0078] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
