Description

Technical Field

[0001] This utility model relates to the field of rubber stopper tooling technology, and in particular to a rubber stopper anti-friction dust generation tooling. Background Technology

[0002] During the drug filling process, the rubber stopper is fed to the sealing robot under the action of the vibrating plate. The sealing robot absorbs and presses the rubber stopper onto the medicine bottle, and then presses on the aluminum cap to complete the sealing.

[0003] However, during the feeding process of the rubber stopper, due to repeated friction with the surface and sidewall of the vibratory feeder, the surface of the rubber stopper is easily worn, generating dust. The dust adheres to the rubber stopper, which not only affects the sealing performance of the rubber stopper, but may also cause the dust to enter the agent, causing the agent to denature and affecting the qualification rate of the packaged product. Therefore, a tooling for preventing friction-generated dust from rubber stoppers is needed. Utility Model Content

[0004] The purpose of this application is to provide a tooling for preventing friction-generated dust from rubber stoppers, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a tooling for preventing friction-generated dust from rubber stoppers, including a vibrating material channel, on which a flexible pad is detachably fixed by means of an installation angle plate. The flexible pad is a flexible body made of flexible material with a smooth surface. The flexible pad includes a U-shaped pad, which is embedded in the vibrating material channel and fits against the inner wall of the vibrating material channel.

[0006] The U-shaped pad has a dust collection hole at its inner bottom, and a cavity is formed inside the U-shaped pad. The dust collection hole is connected to the cavity, and the cavity is also connected to the input end of an external vacuum cleaner fan through a pipe.

[0007] Preferably, the upper end of the U-shaped pad is integrally formed with a top extension extending into the vibrating channel, and the top extension also has a cavity that forms a unified cavity with the cavity on the U-shaped pad.

[0008] Preferably, two top extensions are formed and are integrally formed with the upper ends of both sides of the U-shaped pad, and a gap is formed between the two top extensions. The width of the gap between the two top extensions is less than the minimum width of the rubber stopper.

[0009] Preferably, the inner bottom wall of the U-shaped pad is integrally formed with an anti-sticking flange. Multiple anti-sticking flanges are formed and distributed along the circular circumference of the dust collection hole. There are gaps between the multiple anti-sticking flanges. The upper end of the anti-sticking flange protrudes upward and is higher than the inner bottom wall of the U-shaped pad. The upper end of the anti-sticking flange is rounded around all four sides.

[0010] Preferably, the inner bottom wall of the U-shaped pad, the inner walls of the opposite sides of the U-shaped pad, the inner top wall of the top extension body, and the surface of the anti-adhesion flange are all coated with a smooth and flexible coating.

[0011] Preferably, the mounting angle plate is fixed to the outer wall of the vibrating channel by bolts. There are two mounting angle plates, which are respectively fixed to the upper two sides of the U-shaped pad. The bottom of the U-shaped pad is engaged with the bottom of the vibrating channel.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, by installing a flexible pad on the vibrating conveyor, hard friction between the rubber stopper and the vibrating conveyor is avoided. This allows the rubber stopper to make flexible contact with the outer surface of the U-shaped pad during movement, resulting in less friction between the two. This reduces the probability of friction damage to the rubber stopper and the generation of dust. At the same time, because the U-shaped pad has a cavity, it can absorb the impact force by deforming itself when colliding with the rubber stopper, thereby improving the protection of the rubber stopper. In addition, by opening a dust collection hole and connecting the cavity to the input end of an external vacuum fan through a pipe, any dust that may be generated can be sucked away through the dust collection hole under the action of airflow, preventing dust from adhering to the rubber stopper. This further ensures that the rubber stopper is dust-free after feeding, ensuring the sealing of the package and good quality of the medicine, and improving the qualification rate of the packaged medicine.

[0014] 2. In this utility model, the anti-sticking flange design can prevent the rubber stopper from completely sticking to the bottom of the U-shaped pad, thereby preventing the rubber stopper from being adsorbed at the dust hole and unable to move. While preventing possible dust from adhering to the rubber stopper, it also ensures the smooth delivery of the rubber stopper. Attached Figure Description

[0020] 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.

[0021] Example: Reference Figures 1-3 The tooling shown is a rubber plug anti-friction dust generation tooling, including a vibrating channel 1 of a vibrating plate. A flexible pad 2 is detachably fixed on the vibrating channel 1 by means of an mounting angle plate 3. The flexible pad 2 is a flexible body made of a flexible material (such as silicone) with a smooth surface. The flexible pad 2 includes a U-shaped pad 21, which is embedded in the vibrating channel 1 and fits against the inner wall of the vibrating channel 1.

[0022] The mounting angle plate 3 is fixed to the outer wall of the vibrating material channel 1 by bolts. There are two mounting angle plates 3, which are respectively fixed to the upper two sides of the U-shaped pad 21. The bottom of the U-shaped pad 21 is engaged with the bottom of the vibrating material channel 1.

[0023] The U-shaped pad 21 has a dust collection hole 211 at its inner bottom and a cavity 212 formed inside the U-shaped pad 21. The dust collection hole 211 is connected to the cavity 212. The cavity 212 is also connected to the input end of an external vacuum cleaner (not shown in the figure; the vacuum cleaner is existing technology and will not be described in detail here) through a pipe.

[0024] Based on the above structure, by installing a flexible pad 2 on the vibrating feed channel 1, hard friction between the rubber stopper and the vibrating feed channel 1 is avoided. This allows the rubber stopper to make flexible contact with the outer surface of the U-shaped pad 21 during movement, resulting in less friction between the two and reducing the probability of friction damage to the rubber stopper and the generation of dust. At the same time, since the U-shaped pad 21 has a cavity 212, it can absorb the impact force by deforming itself when it collides with the rubber stopper, thereby improving the protection effect on the rubber stopper. In addition, by opening a dust collection hole 211 and connecting the cavity 212 to the input end of an external vacuum fan through a pipe, any dust that may be generated will be sucked away by the airflow through the dust collection hole 211, preventing dust from adhering to the rubber stopper (i.e., the dust will temporarily fall off during movement and be carried away by the airflow). This further ensures that the rubber stopper is free of dust after feeding, ensuring the sealing of the packaging and the quality of the medicine, and improving the pass rate of the packaged medicine.

[0025] Furthermore, the upper end of the U-shaped pad 21 is integrally formed with a top extension body 22 extending into the vibrating channel 1. The top extension body 22 also has a cavity 212 formed thereon, and it forms a unified cavity with the cavity 212 on the U-shaped pad 21.

[0026] Two top extensions 22 are formed and are integrally formed with the upper ends of the two sides of the U-shaped pad 21 respectively. A gap is formed between the two top extensions 22, and the width of the gap between the two top extensions 22 is less than the minimum width of the rubber stopper.

[0027] By setting the top extension 22, the rubber plug is prevented from popping out of the U-shaped pad 21 when affected by the reset elastic force of the U-shaped pad 21. This not only ensures the protection of the rubber plug, but also prevents the rubber plug from falling out of the vibrating feed channel 1, thus achieving a good performance.

[0028] Furthermore, the inner bottom wall of the U-shaped pad 21 is integrally formed with an anti-sticking flange 23. Multiple anti-sticking flanges 23 are formed and distributed along the circular circumference of the dust hole 211. There are gaps between the multiple anti-sticking flanges 23. The upper end of the anti-sticking flange 23 protrudes upward and is higher than the inner bottom wall of the U-shaped pad 21. The upper end of the anti-sticking flange 23 is formed with rounded corners around its perimeter.

[0029] The anti-stick flange 23 design prevents the rubber stopper from completely sticking to the bottom of the U-shaped pad 21, thus preventing the rubber stopper from being stuck at the dust hole 211 and unable to move. This not only prevents any dust from adhering to the rubber stopper, but also ensures the smooth delivery of the rubber stopper.

[0030] Furthermore, the inner bottom wall of the U-shaped pad 21, the inner walls of the opposite sides of the U-shaped pad 21, the inner top wall of the top extension 22, and the surface of the anti-stick flange 23 are all coated with a smooth flexible coating 24. The smooth flexible coating 24 can be formed by applying a medical-grade hydrogel coating, thereby ensuring that the surface of the entire flexible pad 2 is smoother, further reducing the friction between the flexible pad 2 and the rubber stopper, thereby further reducing the probability of dust generation of the rubber stopper during transportation.

[0031] The working principle of this utility model is as follows: In daily use, the operator only needs to fix the anti-friction dust-generating fixture for the rubber stopper onto the vibrating feed channel 1 using the mounting angle plate 3. By installing a flexible pad 2 on the vibrating feed channel 1, hard friction between the rubber stopper and the vibrating feed channel 1 is avoided, allowing the rubber stopper to make flexible contact with the outer surface of the U-shaped pad 21 during movement. The mutual friction between the two is small, thereby reducing the probability of friction damage to the rubber stopper and reducing the probability of dust generation. At the same time, since the U-shaped pad 21 has a cavity 212, the U-shaped pad 21 can use its own deformation to consume the impact force when it collides with the rubber stopper, thereby improving the protection effect on the rubber stopper. In addition, by opening a dust collection hole 211 and connecting the cavity 212 to the input end of an external dust suction fan through a pipe, any dust that may be generated will be sucked away through the dust collection hole 211 under the action of airflow, preventing any dust from adhering to the rubber stopper. This further ensures that the rubber stopper is free of dust after feeding, ensuring the sealing of the package and the good quality of the medicine, and improving the qualification rate of the packaged medicine.

[0032] In addition, the design of the anti-stick flange 23 can prevent the rubber stopper from completely sticking to the bottom of the U-shaped pad 21, thereby preventing the rubber stopper from being stuck at the dust hole 211 and unable to move. This not only prevents any dust from adhering to the rubber stopper, but also ensures the smooth delivery of the rubber stopper.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
