Description

Technical Field

[0001] The utility model relates to the technical field of coated abrasive manufacturing, and specifically, to a stirring device for improving the uniformity of sizing material. Background Art

[0002] In the production and manufacturing process of coated abrasives, sizing is a key process for bonding the base material and abrasive. Since a large amount of filler is added to the sizing material, during the sizing process, as time goes by, the filler will gradually sink, and in severe cases, stratification will occur, which has an adverse effect on the uniformity of sizing, and ultimately affects the grinding performance of the product, resulting in large fluctuations in product quality.

[0003] In the prior art, for example, the utility model patent with the application number CN202121419543.9 discloses a high-permeability sizing device for abrasive cloth base glue, which consists of a glue tank, a glue-carrying roller, a cloth guiding roller, a sizing roller, a glue-sticking roller, a breast roller, and a sizing roller. The glue-carrying roller and the glue-sticking roller are in the glue tank, and 50% of their areas are immersed in the glue liquid. The breast roller and the sizing roller are located above the glue tank and the two rollers are tangent. The bottom of the cloth guiding roller is at the same height as the bottom of the breast roller, and the top of the sizing roller is at the same height as the top of the breast roller. When this device is used, the glue-carrying roller rotates to adhere the sizing material and then applies it to the base cloth. There is filler added in the glue tank. After long-term use, the filler sinks, making the glue-carrying roller unable to fully contact the filler, affecting the uniformity of sizing.

[0035] Embodiment

[0036] The present utility model will be further described below in conjunction with the accompanying drawings.

[0037] As Figure 1 shown, a stirring device for improving the uniformity of rubber compound provided in this embodiment includes:

[0038] A belt drive assembly, which is arranged above the rubber tank 7;

[0039] A rubber scraping plate 4, the top end of the rubber scraping plate 4 is connected to the belt drive assembly, and the bottom end of the rubber scraping plate 4 extends to the lower part of the rubber compound 6 in the rubber tank 7.

[0040] A plurality of rubber scraping teeth are arranged at intervals at the bottom end of the rubber scraping plate 4.

[0041] The belt drive assembly includes: a driven wheel 1, a belt 2 and a driving wheel 3. The belt 2 is sleeved on the driving wheel 3 and the driven wheel 1. The wheel shaft of the driving wheel 3 is connected to the output end of the servo motor. The belt 2 travels in the horizontal direction, and the belt 2 is connected to the top end of the rubber scraping plate 4.

[0042] The belt drive assembly further includes: a limiting plate 5. Two limiting plates 5 are respectively arranged on both sides of the belt 2, and the rubber scraping plate 4 moves between the two limiting plates 5.

[0043] The distance between the two limiting plates 5 is less than the distance between the side walls of the rubber tank 7.

[0044] The working principle and beneficial effects of the present utility model are as follows:

[0045] For a stirring device for improving the uniformity of rubber compound provided in this embodiment, the driving wheel 3 can rotate clockwise and counterclockwise under the drive of the servo motor. The belt 2 is sleeved on the driving wheel 3 and the driven wheel 1 and is tensioned. The belt can move left and right under the action of the driving wheel 3. The rubber scraping plate 4 is installed on the belt 2 and can move left and right. Limiting plates 5 are installed on the left and right sides above the rubber tank 7. The rubber scraping plate 4 can only move left and right between the two limiting plates 5. The rubber tank 7 contains the rubber compound 6. The rubber scraping plate 4 extends into the bottom of the rubber compound 6. By moving the rubber scraping plate 4 left and right, the rubber compound 6 is stirred, so that the rubber compound 6 always maintains uniform consistency, effectively preventing the filler in the rubber compound 6 from sinking.

[0046] In one embodiment, a pressure sensor is connected to the limiting plate 5, and the controller is connected to the pressure sensor and the servo motor.

[0047] The working principle and beneficial effects of the above technical solution are as follows:

[0048] A pressure sensor is arranged on the limiting plate 5. When the rubber scraping plate 4 moves to contact the limiting plate 5, the pressure sensor transmits the detected pressure data to the controller. After determining that the rubber scraping plate 4 reaches the limit position based on the pressure detection data, the controller controls the servo motor to rotate in the reverse direction, so that the belt 2 drives the rubber scraping plate 4 to move in the reverse direction.

[0049] like Figure 2 , Figure 3 As shown, in one embodiment, a swing assembly is connected between the belt 2 and the scraper 4, the swing assembly is symmetrically arranged in two groups and connected to both ends of the scraper 4, and the swing assembly includes:

[0050] A frame 11, which is connected to the bottom end of the belt 2;

[0051] A rotating rod 12, the rotating rod 12 is rotatably connected to the upper part of the frame 11;

[0052] A worm gear 13, which is rotatably connected to one side of the frame 11 and connected to the rotating rod 12;

[0053] A worm 14, which is tilted and disposed on one side of the frame 11 and meshed with the worm wheel 13;

[0054] The connecting rod assembly is connected between the rotating rod 12 and the scraper plate 4.

[0055] One side of the frame 11 is connected to a slanted worm rack 15 , one side of the worm rack 15 is connected to a motor 16 , and an output end of the motor 16 is connected to the worm 14 .

[0056] The connecting rod assembly includes:

[0057] A first connecting rod 17, one end of which is connected to the rotating rod 12, and the other end of which is connected to the rotating shaft 18;

[0058] A second connecting rod 19, both ends of which are rotatably connected to the scraper plate 4 and the rotating shaft 18;

[0059] The third connecting rod 20 has two ends which are rotatably connected to the scraper plate 4 and the bottom of the frame 11 respectively.

[0060] The first connecting rod 17 , the second connecting rod 19 and the third connecting rod 20 are all symmetrically arranged in pairs with respect to the frame 11 .

[0061] The working principle and beneficial effects of the above technical solution are:

[0062] When the swing assembly is in use, the motor 16 is started to alternately move forward and reverse, the motor 16 drives the worm 14 to rotate, the worm 14 meshes with the worm wheel 13 for transmission, drives the worm wheel 13 to rotate, the worm wheel 13 is connected to the rotating rod 12 and is coaxially arranged, drives the rotating rod 12 to rotate synchronously, the first connecting rod 17 on the rotating rod 12 rotates accordingly, drives the rotating shaft 18 and the second connecting rod 19 to work together, pushes the scraper plate 4 to rotate, the scraper plate 4 is connected to the third connecting rod 20, under the limiting action of the third connecting rod 20, the scraper plate 4 is swung cyclically relative to the frame 11, and the angle of the scraper plate 4 is adjusted.

[0063] Through the above structural design, when the rubber scraping plate 4 moves, the swinging assembly is started at the same time, so that the rubber scraping plate 4 can swing left and right while moving horizontally, turning over and stirring the rubber material 6 in the rubber tank 7 up and down, preventing the phenomenon that the rubber scraping plate 4 only moves horizontally and concentrating the filler on one side during the moving process, further improving the stirring effect of the rubber material, and keeping the rubber material 6 always uniform. The setting of the connecting rod assembly improves the stability of the rubber scraping plate 4 when it moves.

[0064] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0065] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
