Description

Technical Field

[0001] This utility model relates to the field of gasket processing technology, specifically to an automatic polishing machine for gasket production. Background Technology

[0002] Gaskets are sealing components used in machinery, equipment, pipelines—anywhere fluid is present—and are used both internally and externally to provide a seal. Gaskets require polishing during manufacturing to remove burrs from their surface.

[0003] Existing automatic gasket polishing machines use two polishing discs, which rotate in different directions on the upper and lower sides of the gasket, to polish both sides of the gasket simultaneously.

[0004] However, after polishing multiple gaskets, the polishing pad will have a large amount of debris attached to its surface. If this debris is not cleaned, it will harden into small lumps on the surface of the polishing pad, which will not only increase the polishing difficulty of the subsequent gaskets, but also create new polishing defects. Therefore, the polishing pad needs to be cleaned regularly. When cleaning the upper polishing pad, the polished surface of the polishing pad cannot be directly observed, so the personnel need to tilt their heads back to clean the upper polishing pad, which makes the cleaning speed of the polishing pad slower. The debris that is cleaned off may also be accidentally inhaled into the body. Utility Model Content

[0005] The purpose of this invention is to provide an automatic polishing machine for producing sealing gaskets that facilitates the cleaning of polishing discs, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic polishing machine for producing sealing gaskets, comprising a polishing disc one and a polishing disc two, wherein the polishing disc one and the polishing disc two are symmetrically distributed, and further comprising a cleaning structure for cleaning the polished surfaces of the polishing disc one and the polishing disc two. The cleaning structure is installed on the rear side of the polishing disc one and the polishing disc two. The cleaning structure includes a movable mounting frame, on which two symmetrically distributed roller brushes are mounted. Both ends of the roller brushes are fixedly embedded with shafts, and a roller is fixedly sleeved at the end of the shaft away from the roller brush; a support rail for driving the rollers, the support rail being installed on the outside of the cleaning structure; and an impact structure for causing the roller brushes to vibrate, the impact structure being installed between the shafts and the mounting frame.

[0007] Preferably, the shaft is rotatably connected to the mounting frame via a bearing, which reduces the friction between the shaft and the mounting frame, and the roller is connected to the support rail via a rolling connection.

[0008] Preferably, a suction pipe is installed on the rear side of the roller brush. The suction pipe can prevent the swept debris from scattering in the workshop. The suction pipe is fixedly connected to the mounting frame through two symmetrically distributed positioning seats.

[0009] Preferably, a rectangular tube is fixedly embedded on the outer side of the positioning seat, with the rectangular tube facing the contact point between the roller brush and the polishing disc. One end of the suction tube is fixedly connected to a flexible conduit communicating with it, and the end of the flexible conduit away from the suction tube is fixedly connected to the vacuum cleaner.

[0010] Preferably, an electric push rod is fixedly installed at the rear center of the mounting frame, and the connection between the electric push rod and the support rail is a fixed connection, and the electric push rod can drive the mounting frame to move.

[0011] Preferably, the impact structure includes an annular seat fixedly connected to the mounting bracket, and a plurality of sleeves distributed equidistantly in a circular pattern are fixedly embedded on the annular seat, the sleeves being semi-enclosed sleeves.

[0012] Preferably, a striking rod is movably embedded at one end of the sleeve near the shaft, and the striking rod has a hemispherical portion at one end near the shaft, which can reduce the friction between the striking rod and the shaft.

[0013] Preferably, a limiting piece is fixedly connected to one end of the impact rod inside the sleeve, and a spring is movably abutted against the side of the limiting piece away from the impact rod, and the spring can drive the impact rod to move.

[0014] Preferably, the outer side of the roller brush is provided with a plurality of circumferentially equidistant spherical grooves corresponding to the impact rod. The spherical grooves facilitate the impact rod to be embedded into the shaft, and the hemispherical part of the roller brush is in rotatable contact with the shaft through the spherical grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model has a cleaning structure. The electric push rod in the cleaning structure drives the mounting frame to move. During the movement, the mounting frame drives the rollers to roll on the support track surface, so that the roller brush rotates during the movement. This helps to sweep away the debris attached to the polishing surface of the polishing disc. The dust suction pipe then sucks away the swept debris, which helps to automatically clean the polishing disc regularly. This effectively improves the cleaning efficiency of the polishing disc and also prevents the debris from being absorbed by the human body.

[0017] 2. This utility model, by installing an impact structure and spherical slots, allows the impact rod in the impact structure to rotate and contact the shaft under the drive of the spring through multiple spherical slots during the rotation of the shaft. This causes the roller brush to vibrate during its movement and rotation, resulting in better cleaning of the polishing disc and facilitating the dispersion of the cleaned debris. This makes it easier for the vacuum tube to quickly suck up the debris and also prevents debris from accumulating inside the roller brush, thus extending the service life of the roller brush.

[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] Example 1

[0027] Please see Figure 1 , Figure 2 , Figure 3The diagram shows an automatic polishing machine for producing sealing gaskets, including a polishing disc 1 and a polishing disc 2, and a cleaning structure 3 for cleaning the polished surfaces of the polishing discs 1 and 2. The cleaning structure 3 is installed on the rear side of the polishing discs 1 and 2. The cleaning structure 3 includes a movable mounting frame 301, on which two symmetrically distributed roller brushes 302 are mounted. Both ends of the roller brushes 302 are fixedly embedded with shafts 303, and a roller 304 is fixedly sleeved at the end of the shafts 303 away from the roller brushes 302; a support rail 4 for driving the rollers 304, and the support rail 4 is installed on the outside of the cleaning structure 3; and an impact structure 5 for causing the roller brushes 302 to vibrate, which is installed between the shafts 303 and the mounting frame 301.

[0028] Please see Figure 1 , Figure 4 The shaft 303 is rotatably connected to the mounting bracket 301 via a bearing. The bearing can reduce the friction between the shaft 303 and the mounting bracket 301. The roller 304 is connected to the support rail 4 via a rolling connection. A dust suction pipe 305 is installed on the rear side of the roller brush 302. The dust suction pipe 305 can prevent the swept debris from scattering in the workshop. The dust suction pipe 305 is fixedly connected to the mounting bracket 301 via two symmetrically distributed positioning seats 306.

[0029] Please see Figure 2 , Figure 4 A rectangular tube 307 is fixedly embedded on the outer side of the positioning seat 306. The rectangular tube 307 faces the contact point between the roller brush 302 and the polishing disc. One end of the suction pipe 305 is fixedly connected to a soft tube 308 that communicates with it. The end of the soft tube 308 away from the suction pipe 305 is fixedly connected to the vacuum cleaner. An electric push rod 309 is fixedly installed at the center of the rear side of the mounting bracket 301. The connection between the electric push rod 309 and the support rail 4 is a fixed connection. The electric push rod 309 can drive the mounting bracket 301 to move.

[0030] The working principle for easy cleaning of polishing pads: When cleaning polishing pad 1 and polishing pad 2, the electric push rod 309 drives the mounting bracket 301 to move forward. During the forward movement of the mounting bracket 301, the roller 304 rolls on the surface of the support track 4, causing the roller brush 302 to rotate as the polishing surface of the polishing pad moves. This helps to sweep off the debris attached to the polishing surface of the polishing pad. The swept debris is sucked into the dust suction pipe 305 through the rectangular tube 307, preventing the swept debris from spreading in the workshop. This facilitates automatic and regular cleaning of the polishing pads, effectively improving the cleaning efficiency of the polishing pads, and also prevents the debris from being absorbed by the human body.

[0031] Example 2

[0032] Please see Figure 5This embodiment further explains the first embodiment. The impact structure 5 includes an annular seat 501 fixedly connected to the mounting bracket 301. Multiple sleeves 502 are fixedly embedded on the annular seat 501 and are distributed equidistantly in a circle. The sleeves 502 are semi-closed sleeves. A striking rod 503 is movably embedded at one end of the sleeve 502 near the shaft 303. The striking rod 503 has a hemispherical part at one end near the shaft 303. The hemispherical part of the striking rod 503 can reduce the friction between it and the shaft 303.

[0033] Please see Figure 6 The impact rod 503 is located inside the sleeve 502, and one end is fixedly connected to a limiting piece 504. The side of the limiting piece 504 away from the impact rod 503 is movably abutting against a spring 505. The spring 505 can drive the impact rod 503 to move. The outer side of the roller brush 302 is provided with multiple spherical grooves 6 that are equidistantly distributed in a circle at the impact rod 503. The spherical grooves 6 facilitate the impact rod 503 to be embedded into the shaft 303, and the hemispherical part of the roller brush 302 is in rotational contact with the shaft 303 through the spherical grooves 6.

[0034] In this embodiment: during the process of the roller brush 302 rotating and moving to clean the polishing disc, multiple impact rods 503 rotate and contact the shaft 303 through multiple spherical slots 6. Under the action of the compression force of the spring 505, the impact rods 503 rotate and contact the shaft 303 through multiple spherical slots 6, which can cause the shaft 303 and the roller brush 302 to vibrate. This can further improve the cleaning effect of the roller brush 302 on the polishing disc, and also facilitate the vibration and diffusion of the cleaned debris, so that the dust suction pipe 305 can quickly suck up the debris. It can also prevent the debris from accumulating in the roller brush 302 and extend the service life of the roller brush 302.

[0035] Example 3

[0036] Please see Figure 1 This embodiment further illustrates other embodiments, where polishing disc 1 and polishing disc 2 are symmetrically distributed.

[0037] In this embodiment: after the personnel place the sealing gasket on the polishing disc 2, the polishing disc 1 moves down and presses on the upper end of the sealing gasket. Then the polishing disc 1 and the polishing disc 2 rotate in two directions respectively, which can polish both sides of the sealing gasket at the same time.
