Description

Technical Field

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

[0002] A patch is a thin sheet preparation made by making a paste with raw materials and a suitable matrix, which is applied to a backing material for skin application and can produce systemic or local effects. The patch can treat diseases such as joint pain in the human body. During the production process of the patch, the plaster is applied to the backing material by a coating machine. When some coating machines are used in the production of patches, the backing material is conveyed with the plaster through a conveying device, and then the plaster falls onto the backing material through a discharge port through a conveying pipe. Then, as the conveyor continues to move, the plaster on the backing material is flattened by the rotation of the rotating roller. However, the device rotates through the rotating roller and utilizes the contact extrusion force to flatten the plaster. When the rotating roller is in contact with the plaster, there is a lack of limiting elements, resulting in the plaster being squeezed and spread out in an irregular shape, which needs to be improved. At the same time, when the device smoothes the plaster, it is achieved through a single rolling process, which cannot ensure that the plaster can be evenly covered on the backing material. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a uniform coating machine for plaster production. The device can limit the flattening range of the plaster through elastic limiting, thereby improving the subsequent flattening effect of the plaster. At the same time, the device can repeatedly scrape and flatten the plaster through the transmission element, effectively improving the uniformity of the device's application of the plaster, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a uniform coating machine for plaster production, comprising a coating table and a uniform smoothing mechanism;

[0005] Coating station: a conveyor is provided between the front and rear walls, a connecting frame is provided at the upper right end of the coating station, an ointment feeding pipe is provided on the top wall of the connecting frame, and ointment discharge nozzles are evenly distributed through the inner wall of the ointment feeding pipe;

[0006] Evenly smoothing mechanism: It is arranged at the upper left end of the coating table;

[0007] Among them: it also includes a single-chip microcomputer, which is arranged on the front side of the coating table, the input end of the single-chip microcomputer is electrically connected to the external power supply, and the output end of the single-chip microcomputer is electrically connected to the input end of the conveyor. The device can limit the flattening range of the plaster through elastic limiting, thereby improving the subsequent flattening effect of the plaster. At the same time, the device can repeatedly scrape and flatten the plaster through the transmission element, effectively improving the uniformity of the device in applying the plaster.

[0008] Furthermore, the uniform smoothing mechanism includes a fixed frame, an electric push rod, a lifting rod, a cylinder shell, an outer shell, a sleeve, a cross, a rotating shaft, an initial pressure plate and a scraping seat. The fixed frame is arranged at the upper left end of the coating table, and an electric push rod is provided on the upper side of the fixed frame. The input end of the electric push rod is electrically connected to the output end of the single-chip microcomputer, and a lifting rod is provided at the telescopic end of the electric push rod. The lower side of the lifting rod is provided with a uniformly distributed cylinder shell, the outer side of the cylinder shell is slidably connected to the outer shell, the outer side of the outer shell is slidably connected to the sleeve, the inner wall of the outer shell is provided with a cross, the middle part of the cross is rotatably connected to the rotating shaft through a bearing, the lower side of the rotating shaft is provided with an initial pressure plate, and the lower side of the initial pressure plate is provided with a scraping seat, which limits the spreading range of the plaster and can repeatedly scrape the plaster for multiple times.

[0009] Furthermore, the uniform smoothing mechanism also includes a telescopic column and a spring, which are evenly arranged between the outer shell and the adjacent sleeve respectively, and the springs are movably connected to the outer ends of the adjacent telescopic columns. The spring compresses the elastic force so that after the ointment is scraped flat, the sleeve and the outer shell slide relative to each other and reset.

[0010] Furthermore, the uniform smoothing mechanism also includes an annular heating tube, which is arranged inside the initial pressing plate. The input end of the annular heating tube is electrically connected to the output end of the single-chip microcomputer, so as to prevent the ointment from solidifying on the initial pressing plate or the scraping seat by heating.

[0011] Furthermore, the uniform smoothing mechanism also includes a guide groove, an annular slide and a spiral guide groove. The guide grooves are all opened on the outside of the rotating shaft, the inside of the guide grooves are slidably connected with the annular slide, the inner wall of the outer shell is opened with a spiral guide groove, and the outer side of the annular slide is slidably connected with the adjacent spiral guide groove through a guide rod, so that the initial pressure plate is driven to rotate during the downward movement of the cylinder shell.

[0012] Furthermore, the uniform smoothing mechanism also includes a torsion spring, which is arranged on the lower side of the annular slide, and the other end of the torsion spring is fixedly connected to the upper side of the adjacent cross, and the torsion spring is movably sleeved on the outer side of the adjacent rotating shaft. The torsion force of the torsion spring causes the initial pressure plate to rotate upward and reset after the ointment is scraped flat.

[0013] Furthermore, the uniform smoothing mechanism also includes grooves and limit rods, and the limit rods are evenly arranged on the outside of the cylinder shell. The outside of the outer shell is provided with grooves, and the lower ends of the limit rods are slidably connected to adjacent grooves, so that there is partial torque inside after the torsion spring is reset.

[0014] Furthermore, a solenoid valve is serially connected in the middle of the ointment discharge nozzle, and the input end of the solenoid valve is electrically connected to the output end of the single-chip microcomputer, so as to control the opening and closing time of the ointment discharge nozzle.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] When the ointment discharge nozzle is discharging the ointment, the sleeve corresponds to the vertical position of the ointment and the backing material on the conveyor on the lower side. Then the single-chip microcomputer starts the electric push rod to make the cylinder shell indirectly drive the sleeve to move downward, thereby wrapping the ointment on the backing material in a ring shape to prevent the ointment from exceeding the specified coverage range during the subsequent scraping and leveling process, thereby improving the subsequent flattening effect of the ointment. As the cylinder shell moves downward, the sleeve and the shell slide relative to each other, and the telescopic end of the telescopic column and the spring elastically contract, thereby causing the initial pressure plate to move downward to perform a preliminary flattening process on the ointment on the backing material. In this process, since the initial torsion force of the torsion spring is greater than the compression force of the spring, the solid cylinder shell does not slide vertically along the shell, and when the bottom of the shell is flush with the bottom of the sleeve. Afterwards, as the cylinder shell continues to move downward, the annular slide is pressed and moved downward, and the annular slide rotates and slides along the spiral guide groove through the guide rod, so that the annular slide drives the rotating shaft to rotate during the downward movement of the guide groove, and the rotating shaft drives the scraping seat to rotate through the initial pressure plate, and the torsion force of the torsion spring continues to increase. The scraping seat is continuously rotated to repeatedly scrape and level the ointment on the backing material, thereby improving the uniformity of the ointment applied by the device, and is easy to use. The uniform coating machine for the production of the plaster can limit the flattening range of the plaster through elastic limiting, thereby improving the subsequent flattening effect of the plaster, and at the same time, the device can repeatedly scrape and level the plaster through the transmission element, effectively improving the uniformity of the plaster applied by the device.

Annular slide 815 and spiral guide slot 816. The guide slot 814 is provided on the outside of the rotating shaft 810. The inside of the guide slot 814 is slidably connected with the annular slide 815. The inner wall of the shell 805 is provided with a spiral guide slot 816. The outer side of the annular slide 815 is slidably connected with the adjacent spiral guide slot 816 through a guide rod. The uniform smoothing mechanism 8 also includes a torsion spring 817.

When the ointment discharge nozzle 6 discharges the ointment, the sleeve 806 corresponds to the vertical position of the ointment and the backing material on the conveyor 3 on the lower side, and then the single-chip microcomputer 2 starts the electric push rod 802 so that its telescopic end drives the lifting rod 803 to move vertically downward, and the lifting rod 803 drives the cylinder shell 804 to continue to move downward, and the cylinder shell 804 indirectly drives the sleeve 806 to move downward, so as to perform a ring wrapping on the ointment on the backing material to prevent the ointment from exceeding the specified coverage range during the subsequent scraping and leveling process, thereby improving the subsequent flattening effect of the ointment, and as the cylinder shell 804 continues to move downward, the sleeve 804 and the shell 805 slide relative to each other,The telescopic end of the telescopic column 807 and the spring 808 elastically contract, so that the initial pressure plate 811 moves down to perform a preliminary flattening treatment on the ointment on the backing material. In this process, since the initial torsion force of the torsion spring 817 is greater than the compression force of the spring 808, the solid cylinder shell 804 does not slide vertically along the shell 805. When the bottom of the shell 805 is flush with the bottom of the sleeve 806, as the cylinder shell 804 continues to move downward, the annular slide 815 is pressed and moves downward. The annular slide 815 rotates and slides along the spiral guide groove 816 through the guide rod, so that the annular slide 815 drives the rotating shaft 810 to rotate during the downward movement of the guide groove 814. The rotating shaft 810 drives the scraping seat 812 to rotate through the initial pressure plate 811, and the torsion force of the torsion spring 817 increases continuously. The ointment on the backing material is repeatedly scraped and flattened through the continuous rotation of the scraping seat 812, thereby improving the uniformity of the ointment applied by the device, being easy to use, and having a single The tablet machine 2 starts the annular heating tube 813 to heat the initial pressing plate 811 to prevent the ointment from solidifying to the initial pressing plate 811 or the scraping seat 812 during the smoothing process. After the ointment on the backing material is scraped flat, the single chip computer 2 controls the electric push rod 802 to move its telescopic end upward and reset, and the torsion of the torsion spring 817 is used to rotate and move upward to reset. In this process, the sliding engagement of the limit rod 819 and the groove 818 is used to limit the maximum sliding distance of the cylinder shell 814 relative to the outer shell 805, thereby ensuring that there is some torsion inside the torsion spring 817 when the initial pressing plate 811 is reset, and the sleeve 806 is reset by the compression elastic force of the spring 808. The uniform coating machine for the production of the plaster can limit the flattening range of the plaster through elastic limiting, thereby improving the subsequent flattening effect of the plaster. At the same time, the device can repeatedly scrape the plaster through the transmission element, effectively improving the uniformity of the plaster application by the device;

[0025] Among them: it also includes a single chip microcomputer 2, which is arranged at the front side of the coating station 1, the input end of the single chip microcomputer 2 is electrically connected to the external power supply, and the output end of the single chip microcomputer 2 is electrically connected to the input end of the conveyor 3, which is convenient for controlling electrical components.

[0026] The working principle of a uniform coating machine for plaster production provided by the utility model is as follows: when the device is used to produce medical plasters, the ointment delivery tube 5 is first connected to the external ointment delivery device, and then the single-chip microcomputer 2 starts the conveyor 3 to transport the backing material from left to right. When the backing material moves to the bottom of the ointment discharge nozzle 6, the single-chip microcomputer 2 closes the conveyor 3, and the single-chip microcomputer 2 opens all the solenoid valves 7, so that the ointment flows to the backing material through the ointment discharge nozzle 6. The single-chip microcomputer 2 controls the opening and closing time of the solenoid valve 7 to be the same each time, so that the ointment discharge amount of the ointment discharge nozzle 6 is the same each time. When the ointment discharge nozzle 6 is discharging the ointment, the sleeve 806 and the lower side of the delivery nozzle 6 are in contact with each other. The ointment on the conveyor 3 corresponds to the vertical position of the backing material, and then the single-chip computer 2 starts the electric push rod 802 so that its telescopic end drives the lifting rod 803 to move vertically downward, and the lifting rod 803 drives the cylinder shell 804 to continue to move downward, and the cylinder shell 804 indirectly drives the sleeve 806 to move downward, so as to wrap the ointment on the backing material in a ring, so as to prevent the ointment from exceeding the specified coverage range during the subsequent scraping and leveling treatment of the ointment, thereby improving the subsequent flattening effect of the ointment, as the cylinder shell 804 continues to move downward, the sleeve 804 and the shell 805 slide relative to each other, and the telescopic end of the telescopic column 807 and the spring 808 elastically contract, so that the initial pressing plate 811 moves downward to perform a preliminary flattening treatment on the ointment on the backing material. In this process, Since the initial torsion force of the torsion spring 817 is greater than the compression force of the spring 808, the solid cylinder shell 804 does not slide vertically along the shell 805. When the bottom of the shell 805 is flush with the bottom of the sleeve 806, as the cylinder shell 804 continues to move downward, the annular slide 815 is pressed downward, and the annular slide 815 rotates and slides along the spiral guide groove 816 through the guide rod, so that the annular slide 815 drives the rotating shaft 810 to rotate during the downward movement of the guide groove 814. The rotating shaft 810 drives the scraping seat 812 to rotate through the initial pressure plate 811. The torsion force of the torsion spring 817 continues to increase, and the ointment on the backing material is repeatedly scraped and leveled through the continuous rotation of the scraping seat 812, thereby improving the device's The ointment is evenly applied and easy to use. At the same time, the single-chip computer 2 starts the annular heating tube 813 to heat the initial pressure plate 811 to prevent the ointment from solidifying on the initial pressure plate 811 or the scraping seat 812 during the smoothing process. After the ointment on the backing material is scraped flat, the single-chip computer 2 controls the electric push rod 802 to move its telescopic end upward and reset, and the initial pressure plate 811 is rotated and moved upward and reset through the torque of the torsion spring 817. In this process, the maximum sliding distance of the cylinder shell 814 relative to the outer shell 805 is limited by the sliding engagement of the limit rod 819 and the groove 818, thereby ensuring that there is partial torque inside the torsion spring 817 when the initial pressure plate 811 is reset, and the sleeve 806 is reset by the compression elastic force of the spring 808.

The single chip microcomputer 2 controls the conveyor 3, the solenoid valve 7, the electric push rod 802 and the annular heating tube 813, all of which adopt the methods commonly used in the prior art.
