Description

Technical Field

[0001] The present invention relates to the field of plaster packaging, in particular to a plaster making device and a making method thereof for plaster patch production. Background Art

[0002] Plaster packaging refers to a packaging technology that uses injection equipment to introduce a paste-like gelatin refined from numerous medicinal materials onto the surface of the adhesive material.

[0003] Plasters are mainly composed of paste-like colloid and adhesive materials. Among them, paste-like colloid, which is concentrated with many drug ingredients, has the following packaging difficulties:

[0004] ① First, the flow capacity is weak, the speed of single filling into the syringe is extremely slow, and the mechanical filling speed has no obvious advantage over manual filling;

[0005] ② Secondly, the adhesion is strong and the adhesion time in the injection tube is long, so the injection tube needs to be cleaned regularly.

[0006] In order to solve the above problems, current manufacturers mostly preheat the gel to improve its flowability and promote the rapid filling of the paste gel into the injection tube. However, based on the actual results, firstly, the gel in the hot-melt state has a certain volatility, and there is a risk of loss of the active ingredients of the drug. Secondly, after injection, the gel in the hot-melt state is very likely to flow on the surface of the attached material, that is, the shape cannot be fixed after packaging, which is not friendly to subsequent processing steps.

[0007] Therefore, based on the above-mentioned limitations of use, there is a need for a packaging device that can quickly fill paste-like colloids at room temperature and, during the rapid filling, can adjust the single injection volume according to specific usage requirements.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0035] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0036] Example 1

[0037] In this embodiment, a device for making ointments for producing plasters is provided, comprising a packaging mechanism and a control mechanism. The control mechanism is a drive structure that is in rolling contact with a conveyor belt. The packaging mechanism and the control mechanism are arranged vertically. The packaging mechanism comprises a negative pressure filling assembly 2 and a stirring assembly 3 connected to the control mechanism. The stirring assembly 3 is slidably adapted to the negative pressure filling assembly 2, so that the stirring assembly 3 rises or falls in the negative pressure filling assembly 2 under the drive of the control mechanism.

[0038] The negative pressure filling component 2 includes an installation box 21 that is slidably adapted to the stirring component 3 and a filling chamber 24 placed in the installation box 21. One side of the filling chamber 24 is provided with a pipe fitting inserted into the colloid container. The pipe fitting includes a hollow tube 27 placed in the colloid container and a glue outlet pipe 26 placed in the filling chamber 24. The glue outlet pipe 26 is connected to the hollow tube 27. A negative pressure part is provided in the pipe fitting, and the negative pressure part is connected to the stirring component 3. The negative pressure part moves up and down into the pipe fitting, and is used to generate negative pressure in the pipe fitting when rising, and generate downward pressure in the pipe fitting when descending.

[0039] Please refer to Figure 1-7The control mechanism is in rolling contact with the conveyor belt, and the kinetic energy generated when the control mechanism is in contact with the conveyor belt is applied to the stirring component 3, so that the stirring component 3 can move up or down relative to the negative pressure filling component 2. Along with the rising or falling movement, the negative pressure component placed in the pipe can generate negative pressure in the pipe when rising, and generate downward pressure in the pipe when descending.

[0040] Specifically, the premise for generating negative pressure is that the negative pressure member moves upward relative to the tube member. During the upward movement, the multiple small holes arranged at the hollow tube 27 serve as an introduction channel to suck the colloid into the hollow tube 27 under the support of negative pressure.

[0041] In addition, when the negative pressure member moves downward compared to the tube, the colloid sucked into the hollow tube 27 is pressed into the sub-filling chamber 24 through the glue outlet pipe 26. Moreover, as the negative pressure member moves downward, the air pressure in the sub-filling chamber 24 increases, prompting the colloid placed in the sub-filling chamber 24 to be discharged outwardly from the injection tube 1 to complete the injection of the colloid.

[0042] How the control mechanism operates and how the negative pressure piece produces pressure changes in the pipe is analyzed in detail through the following specific implementation process:

[0043] In a specific implementation, the negative pressure member includes a plug 28 placed in the pipe fitting, and the plug 28 extends in two directions relative to the pipe fitting. One end of the plug 28 is connected to the stirring assembly 3, and the other end of the plug 28 is connected to the back plate 22. A sealing ring 25 that is slidably adapted to the plug 28 is provided on the adjacent side of the back plate 22. A return spring 23 is provided around the plug 28 between the sealing ring 25 and the back plate 22. The two ends of the return spring 23 are respectively docked with the sealing ring 25 and the back plate 22, so as to make the sealing ring 25 close to the end of the rubber outlet pipe 26, so as to generate negative pressure in the rubber outlet pipe 26 when the plug 28 is raised; wherein, the plug 28 includes a plug body and a plug rod placed in the pipe fitting, the plug body and the pipe fitting are slidably adapted, and the plug rod is inserted into the plug body and extends outward from the pipe fitting in both directions.

[0044] like Figure 5-7 As shown, the negative pressure member generates negative pressure in the pipe, mainly because the plug 28 moves upward relative to the pipe, so that the sealing ring 25 supported by the return spring 23 seals the pipe port. After sealing, the plug 28 continues to move upward to generate negative pressure in the pipe.

[0045] On the contrary, when the plug 28 moves downward relative to the tube, the sealing ring 25 releases the blockage of the tube port, and in the continued downward movement, the colloid placed in the tube is pushed into the sub-filling chamber 24. Moreover, as the plug 28 moves downward relative to the tube, the air pressure in the sub-filling chamber 24 increases, so that the colloid placed in the sub-filling chamber 24 can be discharged outward from the injection tube 1 to complete the injection of the colloid.

[0046] In a specific implementation, the stirring assembly 3 includes an insertion rod 32 inserted into the mounting box 21, and the insertion rod 32 can be slidably adapted in the mounting box 21. Compared with the mounting box 21, both ends of the insertion rod 32 extend in two directions. Compared with the mounting box 21, the end of the insertion rod 32 extending outward is connected to a linkage frame 31, and the linkage frame 31 is connected to a plug 28, which is used to move up or down into the colloid container under the drive of the control mechanism.

[0047] like Figure 5-7 As shown, how the stirring component 3 performs the stirring action in the colloid container mainly depends on the linkage frame 31 being driven by the insertion rod 32 to move up or down in the colloid container, that is, the upward or downward movement enables the linkage frame 31 to stir the colloid placed in the colloid container.

[0048] In a specific implementation, the injection tube 1 is installed at one end of the installation box 21 away from the pipe fitting, and the injection tube 1 is connected to the filling chamber 24 .

[0049] In a specific implementation, the control mechanism includes a support assembly 4 connected to the mounting box 21 and a rolling assembly 5 rotatably connected to the support assembly 4. The rolling assembly 5 is in rolling contact with the conveyor belt. Specifically:

[0050] The support assembly 4 includes a sleeve 42 installed on the mounting box 21, a poking rod 41 connected to the insertion rod 32 is slidably sleeved in the sleeve 42, a wheel frame 44 is installed on the side of the poking rod 41 away from the insertion rod 32, and the wheel frame 44 is a U-shaped bracket for fixing the rolling assembly 5. A support spring 43 is installed between the wheel frame 44 and the sleeve 42 and is sleeved on the poking rod 41. The two ends of the support spring 43 are respectively in contact with the wheel frame 44 and the sleeve 42.

[0051] The rolling assembly 5 includes a roller 55 rotatably mounted on the wheel frame 44. The roller 55 is a wheel body with an annular cavity inside. A main arm 52 is fixed in the annular cavity. A transfer arm 53 is rotatably mounted on one end of the main arm 52. A rotating wheel 54 is rotatably mounted on the end of the transfer arm 53 facing away from the main arm 52. The rotating wheel 54 is used for the transfer arm 53 to roll in contact with the conveyor belt when it extends outward from the roller 55.

[0052] like Figure 1-3 As shown, the rolling assembly 5 is an adjustment assembly that adjusts the movement amplitude of the support assembly 4 in rolling contact with the conveyor belt by changing its own size. That is, by rotating the transfer arm 53 relative to the main arm 52, the extension amount of the transfer arm 53 relative to the roller 55 is adjusted, so that the rolling contact between the rolling assembly 5 and the conveyor belt is completed when the rotating wheel 54 provided at the transfer arm 53 is in rolling contact with the conveyor belt.

[0053] Among them, the extension amount of the connecting arm 53 relative to the roller 55 is proportional to the amplitude of the movement of the rolling component 5 driving the supporting component 4, that is, the greater the extension amount, the greater the movement amount of the poking rod 41 relative to the sleeve 42, on the contrary, the smaller the extension amount, the smaller the movement amount of the poking rod 41 relative to the sleeve 42, until the connecting arm 53 is completely rotated into the roller 55, and the kinetic energy of the poking rod 41 to move relative to the sleeve 42 cannot be generated.

[0054] As for how the support assembly 4 drives the insertion rod 32 to move, after the insertion rod 32 is connected to the poking rod 41, the insertion rod 32 is driven synchronously.

[0055] In a specific implementation, the clamping bolt 51 is arranged at the joint between the transfer arm 53 and the main arm 52 , and both ends of the clamping bolt 51 are threadedly connected to the roller 55 to adjust the tightness between the transfer arm 53 and the main arm 52 .

[0056] like Figure 1-3 As shown, after the transfer arm 53 is rotated and adjusted relative to the main arm 52, it is tightened by the clamping bolt 51, that is, the clamping bolt 51 is threadedly connected to the side wall of the roller 55, so that in the threaded connection, the side wall of the roller 55 applies a relative clamping force to increase the contact friction between the main arm 52 and the transfer arm 53, so as to fix the relative position of the main arm 52 and the transfer arm 53.

[0057] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
