Description

Technical Field

[0001] The utility model relates to the field of transdermal patch production, in particular to a coating machine for transdermal patch production. Background Art

[0002] A patch is a thin sheet-like preparation that can be applied to the skin and can produce systemic or local drug effects. It consists of a backing layer, a drug reservoir with or without a controlled-release membrane, an adhesive layer, and a protective layer that must be removed before use. Patches can be applied to the entire skin surface, as well as to diseased or incomplete skin surfaces. Patches that are applied to intact skin surfaces and can deliver drugs through the skin into the bloodstream are called transdermal patches. Modern transdermal patches are patches or patch medications that are absorbed through the skin and, through a controlled-release mechanism, deliver the drug rapidly and persistently throughout the body at the dose required for the condition.

[0003] A Chinese patent discloses a coating machine for transdermal patch production (authorization announcement number CN 218691121U). This patented technology can solve the problems of current transdermal patch coating machines, such as complex tool installation steps and difficulty in adjusting the scraper angle and scraper height during use.

[0004] At present, a single scraper method is still used. When the scraper needs to be replaced, it still needs to be disassembled, which is cumbersome to operate and has poor device stability. Utility Model Content

[0006] Preferably: an annular disk is arranged on the left and right side walls of the fixed roller, a plurality of first plug rods are installed along the circumferential direction of the inner end of the annular disk, a threaded groove is opened on the outer wall of the connecting shaft, an annular sleeve is screwed on the outer wall of the threaded groove, and a second plug rod is installed on the outer wall of the annular sleeve by plugging.

[0007] Preferably: an inner groove is opened at the inner end of the fixing frame, an adjusting screw is rotatably installed on the bottom of the inner groove through a bearing, an adjusting slider is installed on the outer wall of the adjusting screw, a connecting shaft is installed on the inner end of the adjusting slider, a handle is installed on the upper end surface of the adjusting screw, the outer wall of the handle is made of magnetic material, an annular magnetic plate is installed on the outer wall of the handle, and a spring rod is installed on the outer end of the annular magnetic plate.

[0008] Preferably: a sleeve is installed on the inner end of the adjusting slider, a slide rod is installed on the inner end of the sleeve by sliding fit, a limit rod is installed on the inner end of the slide rod through a bearing rotation, a plurality of positioning grooves are opened on the outer end of the annular disk along its circumferential direction, and the limit rod is screwed into the positioning groove.

[0009] The technical effects and advantages of this utility model are:

[0010] 1. The utility model adopts a fixed roller structure. By rotating the fixed roller, the scraper can be easily replaced without manual disassembly, which increases the versatility of the device and improves production efficiency.

[0011] 2. The utility model adopts an adjustable screw structure to facilitate the adjustment of the scraper height, and adopts an annular magnetic plate structure to attract and fix the outer wall of the handle, thereby avoiding accidental deflection of the handle and improving the stability of the device during operation.

DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0019] See also Figures 1 to 5 In this embodiment, a coating machine for transdermal patch production is provided, which includes a support 1 and a fixed roller 2. A fixing frame is symmetrically installed on the upper end surface of the support 1, and a connecting shaft 11 is arranged on the inner end of the fixing frame. The inner end of the connecting shaft 11 is rotatably mounted with a fixed roller 2 through a bearing. The outer wall of the fixed roller 2 is provided with a plurality of placement grooves along its circumferential direction, and a scraper 12 is installed in the placement groove by a snap-fit ​​manner. When working, the transdermal patch is placed on the support 1 to facilitate the scraper 12 to coat it. By rotating the fixed roller 2, the scraper 12 is conveniently replaced without manual disassembly, which improves the wide use of the device and improves production efficiency.

[0020] An annular disk 13 is arranged on the left and right side walls of the fixed roller 2, and a plurality of first plug rods 14 are installed on the inner end of the annular disk 13 along its circumferential direction. A threaded groove is provided on the outer side wall of the connecting shaft 11, and an annular sleeve 15 is screwed on the outer side wall of the threaded groove. A second plug rod is installed on the outer side wall of the annular sleeve 15 by plugging. When working, the annular disk 13 limits and fixes the scraper 12 to prevent it from falling off. The annular sleeve 15 limits the annular disk 13. By rotating the annular sleeve 15 outward, the annular disk 13 can be driven to slide, and the second plug rod limits the annular sleeve 15.

[0021] An inner groove is provided at the inner end of the fixing frame, and an adjusting screw 16 is rotatably installed at the bottom of the inner groove through a bearing, an adjusting slider is installed on the outer wall of the adjusting screw 16, a connecting shaft 11 is installed on the inner end of the adjusting slider, and a handle 23 is installed on the upper end face of the adjusting screw 16. The outer wall of the handle 23 is made of magnetic material, and an annular magnetic plate 22 is installed on the outer wall of the handle 23. A spring rod 24 is installed on the outer end of the annular magnetic plate 22. When working, the handle 23 is rotated and the adjusting screw 16 is rotated, thereby adjusting the upper and lower heights of the scraper 12, which improves the versatility of use of the device. The annular magnetic plate 22 attracts and fixes the outer wall of the handle 23 to avoid accidental deflection of the handle 23, thereby improving the stability of the device when working.

[0022] The inner end of the adjusting slider is installed with a sleeve 17, and the inner end of the sleeve 17 is installed with a slide rod 18 by sliding fit. The inner end of the slide rod 18 is rotatably installed with a limit rod 19 through a bearing. The outer end of the annular disk 13 is provided with a plurality of positioning grooves 21 along its circumferential direction. The limit rod 19 is screwed into the positioning groove 21. When working, the limit rod 19 limits the fixed roller 2 to prevent it from rotating accidentally. When the scraper 12 is adjusted, the limit rod 19 is rotated to disengage it from the positioning groove 21, thereby releasing the limiting state of the fixed roller 2 and allowing it to be rotated and adjusted.

[0023] During specific operation, the transdermal patch is placed on the support 1 to facilitate the scraper 12 to coat it. By rotating the fixed roller 2, the scraper 12 can be easily replaced without manual disassembly, which improves the versatility of the device and improves production efficiency.
