Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device for soft capsule compression molds. Background Technology

[0002] During the production process, the surface of the soft capsule compression mold is prone to residual adhesive liquid, medicine and other sticky materials. If cleaning is not thorough, it will lead to scale buildup on the mold surface, reduced product quality (such as color spots and defects), and even affect the subsequent shot compression accuracy.

[0003] Manual brushing, as a traditional cleaning method, requires operators to repeatedly wipe the mold surface with a brush dipped in cleaning agent. Its cleaning efficiency depends entirely on the speed of manual operation, which is difficult to adapt to the pace requirements of large-scale production. Moreover, long-term repetitive labor will significantly increase the labor intensity of operators and easily lead to fatigue. Due to the differences in wiping force, path and amount of cleaning agent used by different operators, the cleaning effect of the mold is obviously unstable. Some areas may have material residue due to inadequate wiping, while other areas may have surface damage due to excessive wiping. More importantly, the mold surface usually has precision textures for forming soft capsules. When manually brushing, the brush cannot penetrate into the texture, resulting in the long-term accumulation of residual material in the texture. This not only increases the cleaning difficulty, but also gradually affects the forming accuracy of the mold and reduces the product qualification rate.

[0004] In view of this, we propose a cleaning device for soft capsule compression molds. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device for soft capsule compression molds, which solves the problems of low efficiency and unstable cleaning effect of manual brushing of soft capsule compression molds.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cleaning device for soft capsule compression molds includes a support frame with a cleaning mechanism mounted on it. The cleaning mechanism includes: a support member fixedly connected to the support frame; a telescopic motor fixedly connected to the support member; a drive block connected to the output shaft of the telescopic motor; a connecting disc fixedly connected to the bottom of the drive block; a hollow connecting plate rotatably connected to the connecting disc; a telescopic tube connected to the connecting disc and communicating with the inner wall of the hollow connecting plate; a plurality of angled nozzles arrayed at the bottom of the hollow connecting plate; a top cleaning brush fixedly connected to the bottom of the hollow connecting plate; a bottom cleaning brush connected to the support frame; and the bottom cleaning brush and the top cleaning brush being positioned opposite each other. A positioning mechanism is mounted on the drive block for positioning the workpiece.

[0008] Preferably, the positioning mechanism includes a hollow disc component, which is fixedly connected to the housing of the telescopic motor. A drive rod is fixedly connected to the drive block, and a sealing disc is fixedly connected to the end of the drive rod away from the drive block. The outer wall of the sealing disc is piston-connected to the inner wall of the hollow disc component, and the outer wall of the drive rod is piston-connected to the inner wall of the hollow disc component. A connecting pipe is connected to the bottom of the hollow disc component, and a hollow rectangular block is connected to the end of the connecting pipe away from the hollow disc component. The hollow rectangular block is fixedly connected to the top of the support frame, and a movable rectangular block is piston-connected to the inner wall of the hollow rectangular block. A support head is fixedly connected to the outer wall of the movable rectangular block, and rollers are symmetrically arranged on the support head.

[0009] Preferably, the output shaft of the telescopic motor is connected to the drive block via a detachable structure, and a rotating support structure is provided between the connecting disc and the hollow connecting disc.

[0010] Preferably, the telescopic tube is made of a flexible material with elastic recovery capability, and the top cleaning brush and the hollow connecting plate are detachably connected.

[0011] Preferably, the spray direction of the angled nozzle forms a preset angle with the radial direction of the hollow connecting disc, and the inner wall of the hollow disc is provided with a wear-resistant coating.

[0012] Preferably, the outer wall of the sealing disc is provided with a sealing element, and the connecting pipe is a flexible high-pressure pipe.

[0014] By employing the above technical solution, this utility model provides a cleaning device for soft capsule compression molds. It possesses at least the following beneficial effects:

[0015] 1. This utility model, by setting up a cleaning mechanism, can achieve efficient cleaning of the upper and lower surfaces of the mold. The cleaning liquid is sprayed out under high pressure through the array of angled nozzles to wash away residual materials on the mold surface. At the same time, the fluid reaction force is used to rotate the hollow connecting plate, which drives the top cleaning brush to rotate and form a clamping structure with the fixed bottom cleaning brush, thereby realizing mechanical brushing of the upper and lower surfaces of the mold and improving the cleaning effect and efficiency.

[0016] 2. This utility model achieves automatic centering and clamping of the mold by setting up a positioning mechanism. The lifting and lowering action of the drive block, driven by a telescopic motor, moves the drive rod and sealing disc within the hollow disc component. Pneumatic transmission pushes the movable rectangular block to extend or return to its original position, causing the support head and rollers to contact or disengage from the mold. Without an additional power source, cleaning and positioning are linked and controlled, improving positioning stability and operational convenience. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 6As shown, this utility model provides a technical solution: a cleaning device for soft capsule compression molds, including a support frame 1, a cleaning mechanism 2 on the support frame 1, and a support member 21 fixedly connected to the support frame 1. A telescopic motor 22 is fixedly connected to the support member 21, the output shaft of the telescopic motor 22 is connected to a drive block 23, a connecting disc 24 is fixedly connected to the bottom of the drive block 23, a hollow connecting disc 25 is rotatably connected to the connecting disc 24, a telescopic tube 26 is connected to the connecting disc 24, the telescopic tube 26 communicates with the inner wall of the hollow connecting disc 25, a plurality of oblique nozzles 29 are arrayed at the bottom of the hollow connecting disc 25, a top cleaning brush 27 is fixedly connected to the bottom of the hollow connecting disc 25, and a bottom cleaning brush 28 is connected to the support frame 1. The cleaning brush 28 and the top cleaning brush 27 are arranged opposite each other. The telescopic motor 22 drives the drive block 23 to move up and down along the support member 21, which drives the connecting disc 24 and the hollow connecting disc 25 below, the top cleaning brush 27 and the angled nozzle 29 to rise and fall synchronously, adjusting the distance from the mold surface. The cleaning liquid enters the hollow connecting disc 25 through the telescopic tube 26 and is sprayed out under high pressure by the array of angled nozzles 29. On the one hand, it washes away the residual material on the mold surface, and on the other hand, it uses the fluid reaction force to make the hollow connecting disc 25 rotate. The hollow connecting disc 25 can rotate relative to the connecting disc 24. The bottom top cleaning brush 27 rotates with it and forms a clamping structure with the fixed bottom cleaning brush 28 to mechanically clean the upper and lower surfaces of the mold. The drive block 23 is equipped with a positioning mechanism 3, which is used to position the workpiece.

[0027] The positioning mechanism 3 includes a hollow disc component 31, which is fixedly connected to the housing of the telescopic motor 22. A drive rod 32 is fixedly connected to the drive block 23. A sealing disc 33 is fixedly connected to the end of the drive rod 32 away from the drive block 23. The outer wall of the sealing disc 33 is piston-connected to the inner wall of the hollow disc component 31. The outer wall of the drive rod 32 is piston-connected to the inner wall of the hollow disc component 31. A connecting pipe 34 is connected to the bottom of the hollow disc component 31. A hollow rectangular block 35 is connected to the end of the connecting pipe 34 away from the hollow disc component 31. The hollow rectangular block 35 is fixedly connected to the top of the support frame 1. A movable rectangular block 36 is piston-connected to the inner wall of the hollow rectangular block 35. A support head 37 is fixedly connected to the outer wall of the movable rectangular block 36. Rollers 38 are symmetrically arranged on the support head 37. When the telescopic motor 22 drives the drive block 23 to move downward, the drive block 23 synchronously pushes the drive rod 32. 2. The sealing disc 33 moves downward within the hollow disc component 31. Since the outer walls of the sealing disc 33 and the drive rod 32 form a piston sealing structure with the inner wall of the hollow disc component 31, the air inside the hollow disc component 31 is compressed during the downward movement. The compressed air is squeezed into the hollow rectangular block 35 through the connecting pipe 34, which in turn pushes the movable rectangular block 36 inside the hollow rectangular block 35 to extend horizontally toward the center of the mold. Finally, the movable rectangular block 36 drives the support head 37 and the symmetrical rollers 38 to abut against both ends of the mold, realizing automatic centering and clamping of the mold. Conversely, when the telescopic motor 22 drives the drive block 23 to rise, the sealing disc 33 moves upward, creating a negative pressure inside the hollow disc component 31. The movable rectangular block 36 resets under the action of the air pressure difference, and the rollers 38 disengage from the mold to complete the release. The entire process does not require an additional power source. The positioning is directly driven by the lifting action of the cleaning mechanism 2, realizing the linkage control of cleaning and positioning.

[0028] The output shaft of the telescopic motor 22 is detachably connected to the drive block 23 for easy maintenance and replacement. A rotating support structure is provided between the connecting disc 24 and the hollow connecting disc 25 to achieve relative rotation between the two. The telescopic tube 26 is made of a flexible material with elastic recovery capability to adapt to the lifting and lowering movement of the connecting disc 24. The top cleaning brush 27 is detachably connected to the hollow connecting disc 25 for easy replacement of the cleaning brush. The spray direction of the angled nozzle 29 forms a preset angle with the radial direction of the hollow connecting disc 25 to generate a vortex. The hollow disc 31 has a wear-resistant coating on its inner wall to improve the service life of the sealing structure. The outer wall of the sealing disc 33 has a sealing element to enhance the airtightness of the hollow disc 31. The connecting pipe 34 is a flexible high-pressure pipe that can adapt to the relative positional relationship between the hollow disc 31 and the hollow rectangular block 35. The hollow rectangular block 35 is symmetrically distributed along the top of the support frame 1 to achieve uniform clamping of the mold. The contact end face shape of the support head 37 is adapted to the outer periphery of the mold to improve positioning stability.

[0029] In use, the soft capsule compression mold cleaning device of this utility model uses a telescopic motor 22 to drive the drive block 23 to move up and down along the support member 21, which drives the connecting disc 24 and the hollow connecting disc 25 below, the top cleaning brush 27, and the angled nozzles 29 to rise and fall synchronously, adjusting the distance from the mold surface. The cleaning liquid enters the hollow connecting disc 25 through the telescopic tube 26 and is sprayed out under high pressure by the array of angled nozzles 29. On the one hand, it washes away residual materials on the mold surface, and on the other hand, it uses the fluid reaction force to make the hollow connecting disc 25 rotate. The hollow connecting disc 25 can rotate relative to the connecting disc 24. The top cleaning brush 27 at the bottom rotates with it and forms a clamping structure with the fixed bottom cleaning brush 28 to mechanically brush the upper and lower surfaces of the mold.

[0030] When the telescopic motor 22 drives the drive block 23 to move downward, the drive block 23 synchronously pushes the drive rod 32 and the sealing disc 33 to move downward within the hollow disc part 31. Since the outer walls of the sealing disc 33 and the drive rod 32 both form a piston sealing structure with the inner wall of the hollow disc part 31, the air inside the hollow disc part 31 will be compressed during the downward movement. The compressed air is squeezed into the hollow rectangular block 35 through the connecting pipe 34, thereby pushing the movable rectangular block 36 inside the hollow rectangular block 35 to extend horizontally toward the center of the mold. Finally, the movable rectangular block 36 drives the support head 37 and symmetrical rollers 38 to contact both ends of the mold, realizing automatic centering and clamping of the mold; conversely, when the telescopic motor 22 drives the drive block 23 to rise, the sealing disc 33 moves upward, creating a negative pressure inside the hollow disc part 31. The movable rectangular block 36 resets under the action of air pressure difference, and the rollers 38 disengage from the mold to complete the release. The whole process does not require an additional power source. The positioning is directly driven by the lifting action of the cleaning mechanism 2, realizing the linkage control of cleaning and positioning.
