Description

Technical Field

[0001] This utility model relates to a cleaning device, and more particularly to a debris cleaning device for a drum polisher. Background Technology

[0002] The main purpose of a drum polishing machine is to remove surface roughness by placing a large number of steel balls, lime and abrasive in an inclined tank-shaped drum. When the drum rotates, the steel balls and abrasive randomly roll and collide inside the drum to remove surface ridges.

[0003] When using a drum polisher, a certain amount of polishing liquid is added into the drum to assist the polishing material in polishing the workpiece. However, when the polishing is completed and the polishing material and workpiece are poured out, some material will adhere to the inside of the drum and be difficult to remove. Utility Model Content

[0004] The purpose of this invention is to provide a debris cleaning device for a drum polisher to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a debris cleaning device for a drum polisher, comprising a polishing drum, a sealing cap covering the outlet of the polishing drum, a threaded screw rotatably mounted on the outer wall of the polishing drum via a bearing seat, an adjusting seat slidably mounted on the outer wall of the polishing drum, a threaded through hole being formed in the adjusting seat, the threaded through hole being threadedly engaged with the threaded screw, a square insertion hole being formed in the adjusting seat, a connecting plate slidably mounted in the square insertion hole, a insertion groove being formed at one end of the connecting plate, a cleaning scraper slidably mounted inside the polishing drum, a limiting groove being formed on the outer wall of the cleaning scraper, a limiting slider slidably mounted in the limiting groove, the limiting slider cooperating with the insertion groove.

[0006] Preferably, the sealing cover has a slot on its underside, and the slot cooperates with the limiting slider.

[0007] Preferably, a power motor is fixedly connected to one side of the polishing cylinder, and the output end of the power motor is fixedly connected to a threaded screw.

[0008] Preferably, the adjusting seat has a limiting recess, a limiting pin is slidably installed in the limiting recess, and the connecting plate has a limiting hole, with the limiting pin and the limiting hole cooperating with each other.

[0010] Preferably, limiting protrusions are fixedly connected to both sides of the connecting plate and near the front and rear end edges, and a compression spring is fixedly connected in the limiting groove, with the other end of the compression spring fixedly connected to the limiting slider.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The adjustment seat is moved by starting the threaded screw. The movement of the adjustment seat can drive the cleaning scraper to move through the connecting plate. The outer wall of the cleaning scraper is in contact with the inner wall of the polishing cylinder. The movement of the cleaning scraper can scrape the material adhering to the inner wall of the polishing cylinder to one side, which helps to clean the debris on the inner wall of the polishing cylinder. This makes it easier for the operator to clean the debris inside the polishing cylinder and keep the inside of the polishing cylinder clean.

[0013] 2. By moving the end of the connecting plate to the other side to disconnect it from the limiting slider, the connecting plate is prevented from affecting the coverage of the sealing cover.

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a debris cleaning device for a drum polisher, including a polishing cylinder 1, a sealing cover 101 covering the outlet of the polishing cylinder 1, a threaded screw 2 rotatably mounted on the outer wall of the polishing cylinder 1 via a bearing seat, an adjusting seat 3 slidably mounted on the outer wall of the polishing cylinder 1, a threaded through hole 301 opened in the adjusting seat 3, the threaded through hole 301 threadedly engaging with the threaded screw 2, a square insertion hole 302 opened in the adjusting seat 3, a connecting plate 5 slidably mounted in the square insertion hole 302, a groove 502 opened at one end of the connecting plate 5, a cleaning scraper 6 slidably mounted in the polishing cylinder 1, a limiting groove 602 opened on the outer wall of the cleaning scraper 6, a limiting slider 603 slidably mounted in the limiting groove 602, and the limiting slider 603 engaging with the groove 502.

[0024] In this embodiment, the threaded screw 2 is threaded into the threaded through hole 301. Rotation of the threaded screw 2 moves the adjusting seat 3, which in turn moves the connecting plate 5. The insertion slot 502 and the limiting slider 603 cooperate with each other. The connecting plate 5 connects the adjusting seat 3 and the limiting slider 603 together. Movement of the adjusting seat 3, via the connecting plate 5, moves the limiting slider 603, which in turn moves the cleaning scraper 6. The outer wall of the cleaning scraper 6 adheres to the inner wall of the polishing cylinder 1, thus scraping away material adhering to the inner wall of the polishing cylinder 1 to one side, collecting debris and other contaminants for polishing. One end of the polishing cylinder 1 is located inside the polishing cylinder. The user only needs to clean the material collected at one end to assist in cleaning the debris inside the polishing cylinder. The connecting plate 5 is slidably installed inside the insertion square hole 302. The end of the connecting plate 5 can be moved to the other side to disconnect it from the limiting slider 603, so as to avoid the connecting plate 5 affecting the coverage of the sealing cover 101. At the same time, the limiting slider 603 is slidably installed inside the limiting groove 602. The sealing cover 101 covers the outlet of the polishing cylinder 1, which can squeeze the limiting slider 603 into the limiting groove 602, so that the device can perform polishing operations normally and effectively avoid the cleaning structure from affecting the normal use of the polishing cylinder 1.

[0025] To achieve the purpose of restricting the movement of the cleaning scraper 6, the device adopts the following technical solution: a slot is provided under the sealing cover 101, which cooperates with the limiting slider 603; a power motor 201 is fixedly connected to one side of the polishing cylinder 1, and the output end of the power motor 201 is fixedly connected to the threaded screw 2; a limiting recess 4 is provided in the adjusting seat 3, and a limiting pin 401 is slidably installed in the limiting recess 4; a limiting hole 501 is provided in the connecting plate 5, and the limiting pin 401 cooperates with the limiting hole 501.

[0026] With the cooperation of the slot and the limiting slider 603, when the sealing cover 101 covers the outlet of the polishing cylinder 1, the end of the limiting slider 603 will be inserted into the slot. At this time, the sealing cover 101 will restrict the left and right swaying of the cleaning scraper 6. The starting motor 201 can drive the threaded screw 2 to rotate. The threaded screw 2 is threadedly engaged with the threaded through hole 301. The rotation of the threaded screw 2 can drive the adjusting seat 3 to move. The limiting pin 401 and the limiting hole 501 cooperate to fix the connecting plate 5 inside the insertion square hole 302, restricting the connecting plate 5 from moving freely. Since the threaded screw 2 is fixedly installed on the polishing cylinder 1, the polishing cylinder 1 needs to rotate to polish the workpiece. Conventional cable connection cannot provide power to the threaded screw 2. It is necessary to use a more mature brush and commutator to provide power to the threaded screw 2.

[0027] In order to restrict the movement of the connecting plate 5, the device adopts the following technical solution: a spring pad 402 is fixedly connected to the limiting pin 401, a return spring 403 is sleeved on the limiting pin 401, a pull ring 404 is fixedly connected to the upper end of the limiting pin 401, limiting protrusions 503 are fixedly connected to both sides of the connecting plate 5 near the front and rear end edges, a compression spring 604 is fixedly connected in the limiting groove 602, and the other end of the compression spring 604 is fixedly connected to the limiting slider 603.

[0028] The return spring 403 can provide a certain pushing force to the spring pad 402. When the spring pad 402 is pushed, it will drive the limiting pin 401 to insert into the limiting hole 501. The pull ring 404 can drive the limiting recess 4 to move. The limiting protrusion 503 can restrict the connecting plate 5 from moving out of the insertion square hole 302. The compression spring 604 can provide a certain pushing force to the limiting slider 603.

[0029] The working principle and usage process of this utility model are as follows: When using it, the sealing cover 101 needs to be opened and the connecting plate 5 needs to be manually pushed so that the insertion slot 502 is locked on the limiting slider 603. Then, the polishing cylinder 1 is rotated so that its discharge port faces downward. The threaded screw 2 is started to drive the power motor 201 to rotate. The rotation of the power motor 201 can drive the adjusting seat 3 to move. The movement of the adjusting seat 3 can drive the cleaning scraper 6 to move through the connecting plate 5. The outer wall of the cleaning scraper 6 is attached to the inner wall of the polishing cylinder 1. The movement of the cleaning scraper 6 can scrape the material adhering to the inner wall of the polishing cylinder 1 to one side, so that the debris is collected at one end of the polishing cylinder 1. Then, the user only needs to rinse and clean the debris collected at one end.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
