Description

Technical Field

[0001] This utility model relates to the field of transdermal patch technology, and in particular to a composite mechanism for efficient transdermal patch production. Background Technology

[0002] Transdermal patches are a drug delivery system that delivers medication into the body by adhering to the surface of intact skin, thereby producing a systemic therapeutic effect. This method of drug delivery utilizes the permeability of the skin, allowing the drug to be gradually released and enter the bloodstream, avoiding the first-pass effect in the liver and gastrointestinal degradation and inactivation that may occur with oral administration, thus improving the therapeutic effect.

[0003] During the production of transdermal patches, each layer needs to be pressed together using a laminating mechanism to form a complete transdermal patch. However, the pressing effect of a single pressure roller is generally not very good when laminating transdermal patches. In addition, it is difficult to divide the transdermal patch after it has been pressed together by the laminating mechanism. The size of the laminated transdermal patch is relatively large, and it often needs to be further cut, thus increasing the number of processes involved in the production of transdermal patches. Utility Model Content

[0004] The main objective of this invention is to provide a composite mechanism for the production of transdermal patches that is highly efficient, and can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency transdermal patch production composite mechanism includes a worktable, a controller fixedly installed on the front right side of the worktable, an installation plate fixedly installed on the rear right side of the worktable, a set of unwinding rollers fixedly installed on the front end of the installation plate, a support frame fixedly installed on the middle upper part of the worktable, a pressing device fixedly installed on the upper end of the support frame, an installation seat and a fixing seat fixedly installed on the left upper part of the worktable, a cutting device fixedly installed on the front end of the installation seat, and a winding device fixedly installed on the upper end of the fixing seat.

[0007] Preferably, the cutting device includes a primary servo motor and cutting blades. A mounting post is fixedly installed at the output end of the primary servo motor. Several bolt holes are opened at the right end of the mounting post. Three cutting blades are provided, and a fixing bracket is fixedly installed at the center of the front end of each of the three cutting blades. Fixing bolts are installed at the front and rear right ends of each of the three fixing brackets. All three cutting blades are fixedly mounted on the outer surface of the mounting post via the fixing brackets. The primary servo motor is fixedly installed at the front end of the mounting base. The primary servo motor drives the mounting post, and the cutting blades on the outer surface of the mounting post cut the pressed transdermal patch. Since the cutting blades are fixed to the outer surface of the mounting post by the fixing bolts, the installation position of the cutting blades can be adjusted by loosening the fixing bolts, and the number of cutting blades can also be increased or decreased as needed.

[0008] Preferably, the pressing device includes two electrically operated telescopic rods. Each of the two telescopic rods has a connecting plate fixedly mounted at its output end. Three pressure rollers are rotatably mounted between the two connecting plates. The two telescopic rods are respectively inserted and fixedly mounted at the front and rear of the upper end of the support frame. By pushing the two connecting plates downwards with the two telescopic rods, the multiple pressure rollers between the connecting plates press the composite material onto the worktable, thereby pressing the multilayer composite material of the transdermal patch. Furthermore, the design of multiple pressure rollers improves the pressing effect.

[0009] Preferably, the winding device includes a second servo motor, with a mounting bracket fixedly installed at the output end of the second servo motor. A locking block is inserted at the front end of the mounting bracket, and a winding roller is fixedly installed at the front end of the locking block. The second servo motor is fixedly installed on the upper end of the fixed base. The second servo motor drives the mounting bracket, which in turn drives the winding roller to wind up the composite material. Moreover, after the transdermal patch is laminated, the winding roller can be directly pulled out of the mounting bracket via the locking block, facilitating quick installation and removal of the winding roller.

[0010] Preferably, the pressure roller has a hollow design inside.

[0011] Preferably, the front end of the card holder has a card slot, and the card slot and the card block are the same size and corresponding in position.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When it is necessary to laminate transdermal patches, firstly, the composite material of the transdermal patch roll is sequentially sleeved on the outer surface of the unwinding roller. Then, the other end of the composite material is passed through the pressing device and the cutting device and wound around the outer surface of the winding roller on the winding device. Next, two connecting plates are pushed down by two electric telescopic rods. Multiple pressure rollers between the two connecting plates press the composite material down onto the worktable, thereby pressing the multi-layer composite material of the transdermal patch. The design of multiple pressure rollers also improves the pressing effect. Finally, the second servo motor drives the chuck, which in turn drives the winding roller to wind up the composite material. After the transdermal patch is laminated, the winding roller can be directly pulled out of the chuck through the chuck block, which facilitates the quick installation and removal of the winding roller.

[0014] 2. After the pressure rollers press the transdermal patch together, the No. 1 servo motor on the cutting device drives the mounting column. The cutting blade on the outer surface of the mounting column then cuts the pressed transdermal patch. The cutting blade is fixed to the outer surface of the mounting column by the fixing bolts. Therefore, by loosening the fixing bolts, not only can the installation position of the cutting blade be adjusted, but the number of cutting blades can also be increased or decreased as needed, thereby improving the practicality of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1-4 As shown, a composite mechanism for producing high-efficiency transdermal patches includes a workbench 1, a controller 5 fixedly installed on the right front end of the workbench 1, an mounting plate 9 fixedly installed on the rear right end of the workbench 1, a set of unwinding rollers 10 fixedly installed on the front end of the mounting plate 9, a support frame 6 fixedly installed on the middle upper end of the workbench 1, a pressing device 3 fixedly installed on the upper end of the support frame 6, an mounting seat 7 and a fixing seat 8 fixedly installed on the left upper end of the workbench 1, a cutting device 2 fixedly installed on the front end of the mounting seat 7, and a winding device 4 fixedly installed on the upper end of the fixing seat 8.

[0024] The cutting device 2 includes a servo motor 20 and cutting blades 21. A mounting post 22 is fixedly installed at the output end of the servo motor 20. Several bolt holes 23 are opened at the right end of the mounting post 22. Three cutting blades 21 are provided, and each of the three cutting blades 21 has a fixing bracket 24 inserted and fixedly installed at the center of its front end. Fixing bolts 25 are installed at the front and rear right ends of the three fixing brackets 24. All three cutting blades 21 are fixedly installed on the outer surface of the mounting post 22 via the fixing brackets 24. The servo motor 20 is fixedly installed at the front end of the mounting base 7. The servo motor 20 drives the mounting post 22, and the cutting blades 21 on the outer surface of the mounting post 22 cut the pressed transdermal patch. Since the cutting blades 21 are fixed to the outer surface of the mounting post 22 by the fixing bolts 25, the installation position of the cutting blades 21 can be adjusted by loosening the fixing bolts 25, and the number of cutting blades 21 can also be increased or decreased as needed.

[0025] The pressing device 3 includes two electrically operated telescopic rods 30. Each of the two telescopic rods 30 has a connecting plate 31 fixedly mounted at its output end. Three pressure rollers 32 are rotatably mounted between the two connecting plates 31. The two telescopic rods 30 are respectively inserted and fixedly mounted at the front and rear of the upper end of the support frame 6. The pressure rollers 32 have a hollow internal design. By pushing the two connecting plates 31 downwards with the two telescopic rods 30, the multiple pressure rollers 32 between the two connecting plates 31 press the composite material onto the worktable 1, thereby pressing the multi-layer composite material of the transdermal patch. The design of multiple pressure rollers 32 also improves the pressing effect.

[0026] The winding device 4 includes a second servo motor 40, with a card holder 41 fixedly installed at the output end of the second servo motor 40. A card block 42 is inserted at the front end of the card holder 41, and a winding roller 43 is fixedly installed at the front end of the card block 42. The second servo motor 40 is fixedly installed on the upper end of the fixed base 8. The front end of the card holder 41 has a card slot, and the card slot and the card block 42 are the same size and corresponding in position. The electrical equipment of this utility model is all existing technology. The electrical equipment can operate normally during trial operation. Before use, the controller 5 needs to be connected to an external power supply. The controller 5 is electrically connected to the first servo motor 20, the electric telescopic rod 30, and the second servo motor 40. The second servo motor 40 drives the card holder 41, and the card holder 41 drives the winding roller 43 to wind up the composite material. After the transdermal patch is laminated, the winding roller 43 can be directly pulled out of the card holder 41 through the card block 42, which facilitates the quick installation and removal of the winding roller 43.

[0027] It should be noted that this utility model is a composite mechanism for the production of transdermal patches. First, the rolled transdermal patch composite material is sequentially sleeved onto the outer surface of the unwinding roller 10. Then, the other end of the composite material is passed through the pressing device 3 and the cutting device 2 and wound around the outer surface of the winding roller 43 on the winding device 4. Next, two electric telescopic rods 30 push two connecting plates 31 downwards, and multiple pressure rollers 32 between the two connecting plates 31 press the composite material onto the worktable 1, thereby pressing the multi-layer composite material of the transdermal patch. The design of multiple pressure rollers 32 also improves the pressing effect. Finally, the second servo motor 40 drives the card holder 41, which in turn... The take-up roller 43 can be used to take up the composite material. After the transdermal patch is laminated, the take-up roller 43 can be pulled out of the holder 41 directly through the locking block 42, which facilitates the quick installation and removal of the take-up roller 43. At the same time as the take-up, the first servo motor 20 on the cutting device 2 drives the mounting column 22. The cutting blade 21 on the outer surface of the mounting column 22 then cuts the laminated transdermal patch. The cutting blade 21 is fixed to the outer surface of the mounting column 22 by the fixing bolt 25. Therefore, by loosening the fixing bolt 25, not only can the installation position of the cutting blade 21 be adjusted, but the number of cutting blades 21 can also be increased or decreased as needed, thereby improving the practicality of the device.
