Description

Technical Field

[0001] This utility model relates to the field of medicated patch processing technology, and more specifically, to a compaction device for medicated patch production. Background Technology

[0002] Medicated patches are typically composed of multiple materials, such as a backing layer, a drug layer, and a protective film. These materials need to be compacted to ensure a tight bond, guaranteeing the stability and effectiveness of the patch during storage and use. However, existing medicated patch compaction technologies and equipment have many shortcomings.

[0003] Traditional methods of compacting medicated patches often involve manual operation, with workers pressing the patches by hand. This method is not only inefficient and unsuitable for large-scale production, but also results in inconsistent compaction due to variations in the force and technique applied manually, affecting the quality stability of the patches. For example, some patches may not be compacted sufficiently, leading to poor bonding between the layers and potential delamination during subsequent use, reducing the effectiveness of the medication. Conversely, some patches may be over-compressed, damaging the drug layer and affecting the active ingredients.

[0004] With the development of automated production, some medicated patch compaction equipment has gradually emerged. However, existing automated compaction equipment has some problems. The conveying system of some equipment is not precise enough, and the medicated patches are prone to positional deviation during the conveying process, resulting in inaccurate compaction and affecting the overall quality of the medicated patches. Moreover, the compaction mechanism of these devices is not reasonably designed, and the contact method between the compactor and the medicated patch may not be suitable for the special structure of the medicated patch. For example, there may be a protruding structure in the middle of the medicated patch, and ordinary compactor heads cannot accurately match it, thus failing to achieve the ideal compaction effect.

Detailed Implementation

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] like Figures 1-4 The compaction device shown is used for the production of medicated patches 3, including a frame 1, a conveying channel, a compaction mechanism, a control system, and a positioning system.

[0017] The frame 1 is the supporting structure of the entire compaction device. It is equipped with support legs 2 at the bottom to provide stable support for the device, ensuring that the equipment will not shake or tip over during operation, and guaranteeing the stability and reliability of the compaction operation.

[0018] At least one set of conveying channels is set on the frame 1 for continuously conveying single patches 3. The conveying channels include parallel guide rails 4 and a conveyor belt 5 running on the inner lower part. The guide rails 4 guide the conveyor belt 5 to ensure the smooth operation of the conveyor belt 5. The conveyor belt 5 is provided with spaced baffles 6. The baffles 6 on adjacent conveyor belts 5 form a patch station 7 for accommodating single patches 3. The patch 3 is supported by the conveyor belt 5 at the patch station 7 and does not fall. It is limited in four directions by the baffles and guide rails 4. This design allows the patch 3 to be accurately positioned on the conveyor belt 5, avoiding displacement of the patch 3 during the conveying process and providing a precise positional basis for subsequent compaction operations.

[0019] The compaction mechanism is located on the conveying path of the conveying channel and is the key part for compacting the patch 3. The compaction mechanism includes a lower seat 8 fixed on the frame 1 and a pressing head 9 set above the lower seat 8. The lower seats 8 are arranged in an array on the frame 1, and their positions correspond one-to-one with the patch station 7 on the conveyor belt 5. The lower seat 8 is close to the patch 3 above it, but does not contact the lower side of the patch 3. The pressing head 9 is driven by a drive component and can make vertical reciprocating motion relative to the lower seat 8 to realize the compaction operation of the patch 3. The drive component is an array of cylinders 10. The lower end of the piston rod 11 of the cylinder 10 is connected to the pressing head 9. The cylinder 10 can provide stable and controllable pressure to ensure that the pressing head 9 applies uniform pressure to the patch 3, so that all parts of the patch 3 are tightly adhered.

[0020] The control system is electrically connected to the conveying mechanism, the compaction mechanism, and the positioning system, and is the core of the entire device. The control system can receive signals from the positioning system, control the start and stop of the conveyor belt 5, and trigger the compaction mechanism to perform the compaction action. Through precise control, it ensures that the medicated patch 3 is compacted in the accurate position, thereby improving the accuracy of compaction and production efficiency.

[0021] The positioning system includes a first detection unit set on the conveyor belt 5 and a second detection unit set near the compaction station. The first detection unit and the second detection unit cooperate with each other to detect whether the patch station 7 has been conveyed to the designated position. The first detection unit and the second detection unit are photoelectric sensors or proximity switches, which can quickly and accurately detect the position and status of the patch 3, provide reliable signals for the control system, and ensure precise synchronization between the compaction operation and the conveying of the patch 3.

[0022] The lower end face of the pressure head 9 is provided with a positioning groove 12 that matches the ring 13 in the middle of the patch 3. The positioning groove 12 is a shallow circular groove with a diameter greater than the outer diameter of the ring 13 in the middle of the patch 3 and a depth less than the thickness of the ring 13. When pressing, the positioning groove 12 matches the ring 13 in the middle of the patch 3. This design ensures that when the pressure head 9 presses the patch 3, the ointment 16 is located inside the ring 13. The positioning groove 12 can accurately match the protruding structure in the middle of the patch 3, which can ensure the compaction effect in the middle of the patch 3 and improve the compaction quality of the patch 3.

[0023] A top plate 14 is provided above the frame 1. The top plate 14 is supported on the frame 1 by side plates 15. The drive component is fixedly installed on the top plate 14, and the pressure head 9 is located below the top plate 14. This structural design provides a stable installation foundation for the drive component and the pressure head 9, ensuring the stability of the compaction mechanism during operation. At the same time, the frame 1 is provided with multiple sets of compaction mechanisms along the conveying direction of the conveyor belt 5, which can compact the medicated patch 3 multiple times according to the compaction requirements of the patch 3.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
