Description

Technical Field

[0001] This invention belongs to the field of wet adhesive production technology, and particularly relates to a slurry grinding and mixing device for wet adhesive production process. Background Technology

[0002] Silica is a major filler in rubber products, significantly improving the mechanical strength and tear resistance of rubber materials, and is widely used in rubber processing. The process involves first liquidifying silica, then adding it to a rubber latex and mixing thoroughly. The latex is then flocculated, dried, and finally processed to obtain the rubber compound containing silica. However, during the mixing of silica with the rubber latex, its uneven particle size limits its ability to fully integrate with the latex during the fusion and flocculation reaction. It easily precipitates and accumulates at the bottom of the latex, failing to disperse evenly. This results in unsatisfactory addition and dispersion, failing to achieve the goal of significantly improving the physical properties of the rubber material. To address this issue, current methods involve finely grinding silica to ensure the smallest and most uniform particle size before the subsequent fusion reaction between silica and the rubber latex, thus improving the degree of integration and dispersion. However, existing grinding equipment can only perform dry grinding and cannot meet the requirement of simultaneous grinding of silica and rubber latex. Therefore, a new type of grinding equipment is needed to overcome these problems. Summary of the Invention

[0003] The present invention provides a slurry grinding and mixing device for wet adhesive production process.

[0004] This invention is achieved through the following technical solution: It includes a frame assembly and a grinding housing mounted on the frame assembly.

The grinding mechanism includes a grinding disc drive motor, an upper adjustment mechanism, an upper rotating shaft, a stationary grinding disc, a moving grinding disc, a lower adjustment mechanism, and a lower rotating shaft. The grinding disc drive motor is mounted on the top of the grinding housing via the upper adjustment mechanism. The lower end of the grinding disc drive motor has an upper rotating shaft that extends downwards into the interior of the grinding housing. The stationary grinding disc is coaxially fixed inside the grinding housing, and the moving grinding disc is coaxially mounted within the stationary grinding disc, with a clearance fit between them. The top of the moving grinding disc is connected to the upper rotating shaft. The lower adjustment mechanism is located at the bottom of the grinding housing and below the discharge port. A lower rotating shaft is mounted on the lower adjustment mechanism. The lower end of the lower rotating shaft has a lower bearing seat connected to the lower adjustment mechanism, and the upper end extends upwards into the discharge port to connect to the moving grinding disc.

[0005] Furthermore, the stationary grinding disc includes a lower stationary grinding disc and an upper stationary grinding disc, and the moving grinding disc includes a lower moving grinding disc and an upper moving grinding disc. The lower stationary grinding disc and the upper stationary grinding disc are arranged inside the grinding housing from bottom to top. Both the lower stationary grinding disc and the upper stationary grinding disc are coaxially provided with a grinding chamber with a pointed tip and a conical structure. The lower moving grinding disc is coaxially arranged in the lower stationary grinding disc, and the upper moving grinding disc is coaxially arranged in the upper stationary grinding disc. The top of the lower moving grinding disc is connected to the upper moving grinding disc through a lower rotating shaft. The lower moving grinding disc and the upper moving grinding disc are respectively arranged in a conical structure that matches the grinding chamber.

[0006] Furthermore, the upper adjustment mechanism includes an upper mounting plate, an upper mounting support, an upper bearing plate, an upper adjustment drive, guide rods, and a first buffer spring. The upper mounting plate is disposed on the top of the grinding housing. A through hole for the upper rotating shaft to pass through is provided at the center of the upper mounting plate. Guide rods and upper mounting supports are sequentially disposed on the upper mounting plate on both sides of the axis of the through hole. The upper bearing plate is disposed on the two guide rods, which are slidably engaged. The first buffer springs are respectively disposed on the guide rods and push the upper bearing plate upward. An upper adjustment drive is disposed in the middle and upper part of each of the upper mounting supports. The upper adjustment drive is connected downward to the upper bearing plate. A grinding disc drive motor is suspended at the top of the upper mounting support.

[0007] Furthermore, the lowering mechanism includes a lower mounting ring plate, a lower mounting ring seat, a lower bearing ring seat, a lower adjusting motor, a lower adjusting rod, and a second buffer spring. The lower mounting ring seat is configured in a U-shape and is coaxially mounted on the top of the lower mounting ring plate, with the through hole of the lower mounting ring seat coaxial with the discharge port. Lower adjusting rods are respectively provided on both sides of the through hole of the lower mounting ring plate. The lower part of the lower adjusting rod is connected to the frame assembly through a bearing and is drivenly connected to the lower adjusting motor, which is mounted on the frame assembly. The top of the lower adjusting rod is connected to the lower mounting ring seat through a bearing. The lower bearing ring seat is mounted on the two lower adjusting rods and the two are dynamically engaged. The second buffer spring is respectively mounted on the lower adjusting rod and pushes the lower bearing ring seat upward. The top of the through hole of the lower bearing ring seat is provided with a countersunk hole that matches the lower bearing seat. At least one collecting groove is provided in a concentric circle on the lower bearing ring seat around the countersunk hole. The bottom of each collecting groove is provided with a discharge hole that penetrates the lower bearing ring seat downward.

[0008] The beneficial effects of this invention are as follows: This invention has a compact structure. After mixing silica with rubber latex, it is then subjected to multi-stage grinding and crushing with small particle size, which is easy to control and adjust. While dispersing silica, the large-particle silica produced by previous flocculation is sheared and crushed into small-particle silica, which is uniformly dispersed in the rubber latex without agglomeration, thus ensuring complete reaction. This solves the problem of silica precipitation when dissolved in rubber latex as a filler, greatly increasing the amount of silica added and its dispersibility in rubber latex and subsequent rubber products. It significantly improves silica dispersion and enhances interfacial interaction, shortens the reaction time, and significantly improves the physical properties of rubber materials.

The lower adjusting rod (30) is mounted on the frame assembly (1). The top of the lower adjusting rod (30) is connected to the lower mounting ring seat (27) via the bearing (13). The lower bearing ring seat (28) is mounted on the two lower adjusting rods (30) and the two are dynamically matched. The second buffer spring (31b) is mounted on the lower adjusting rod (30) and pushes the lower bearing ring seat (28) upward. The top of the through hole of the lower bearing ring seat (28) is provided with a countersunk hole that matches the lower bearing seat (12).

[0021] The lower adjustment rod (30) is a lead screw, which is connected to the lower bearing ring seat (28) through the lead screw nut. The lead screw and the lower adjustment motor (29) are driven by a belt, gear or chain, so the movement is smooth and easy to control.

[0022] The inner side of the lower mounting ring seat (27) is provided with an elastic guard ring (34) extending downward into the collection groove (32), and the elastic guard ring (34) is in dynamic cooperation with the collection groove (32). The elastic guard ring (34) effectively prevents the mixed adhesive from flowing into the gap between the lower mounting ring seat (27) and the lower bearing ring seat (28).

[0023] The lower moving grinding disc (10) is provided with a through shaft hole (14) coaxial with its axis. A shaft guard tube (16) is coaxially provided at the bottom of the lower moving grinding disc (10) via a flange (15) and extends downward through the lower bearing seat (12).

The shaft guard tube (16) is fixedly connected to the lower bearing seat (12). The lower rotating shaft... (7) passes through the shaft guard tube (16) and the shaft hole (14) to connect to the upper moving grinding disc (11).

The lower rotating shaft (7) is rotated up or down according to the scale of the adjustment scale (17), thereby adjusting the upper moving grinding disc (11) or the lower moving grinding disc (10). The lower rotating shaft (7) is threadedly connected to the shaft hole and the upper moving grinding disc (11). The lower rotating shaft (7) is threadedly connected to the shaft guard tube (16) to ensure that the lower rotating shaft (7) can rotate. At the same time, the shaft guard tube (16) provides support for the lower moving grinding disc (10).

[0024] The lower mounting ring plate (26) has a collection cover (35) that covers each discharge hole (33) upwards in the through hole. The collection cover (35) has a through hole for the shaft guard tube (16) to pass through. The through hole is sealed to the outer wall of the shaft guard tube (16).

[0025] The upper moving grinding disc (11) is provided with a U-shaped material distribution disc (36) at the top or the lower part of the upper rotating shaft (6). Material distribution holes are provided on the side wall of the material distribution disc (36). The feed inlet (4) penetrates into the grinding housing (2) and extends to the top of the material distribution disc (36) to ensure that the mixed adhesive can be discharged into the material distribution disc (36). The material distribution disc (36) disperses the mixed adhesive so that it can flow into the upper stationary grinding disc (9) from all directions for grinding.

[0026] The bottom of the collection hood (35) is provided with a three-way valve (37), one of the other two ports is the discharge port, and the other is connected to the circulation pump (39) and the feed port (4) in sequence through the circulation pipe (38).

[0027] Furthermore, the upper adjustment drive (23) is a pneumatic cylinder or a hydraulic cylinder.

[0028] Furthermore, the lower bearing ring seat (28) has a groove on its bottom surface corresponding to each buffer spring (31) to provide buffer protection.

[0029] Furthermore, the lower stationary grinding disc (8) and the upper stationary grinding disc (9) are connected by a concave-convex fit to enhance the connection strength.

[0030] Furthermore, the top of the upper moving grinding disc (11) and the lower moving grinding disc (10) are provided with a conical guide slope (40) to avoid dead corners of mixed adhesive deposits that cannot be cleaned and will cause pollution to the subsequent mixed adhesive.

[0031] Furthermore, the top of the upper stationary grinding disc (9) is provided with a guide slope (40) to avoid dead corners where mixed adhesive can be deposited and cannot be cleaned, thus preventing contamination of the subsequent mixed adhesive.

[0032] Furthermore, it also includes a control device, which is connected to the grinding disc drive motor (5), the upper position drive (23), and the lower position drive motor (29). The control device is a single-chip microcomputer or a PLC variable logic controller.

[0033] The working principle and method of this invention: Silica and rubber latex are initially mixed evenly in a mixing device to obtain a mixed rubber solution. The grinding disc drive motor (5) of this device is started to drive the lower moving grinding disc (10), the upper moving grinding disc (11), and the material distribution disc (36) to rotate. Then, the mixed rubber solution is transported to the feed port (4) of the grinding housing (2) through a pipeline, and then discharged from the feed port (4) onto the material distribution disc (36). The mixed rubber solution is subjected to the centrifugal force generated by the rotation of the material distribution disc (36), and is scattered onto the inner wall of the grinding housing (2), and then falls and flows between the upper stationary grinding disc (9) and the upper moving grinding disc (11) for further processing. After primary grinding, the mixture flows downward between the lower stationary grinding disc (8) and the lower moving grinding disc (10) for secondary grinding. After grinding, it gathers in the collection trough (32) of the lower bearing ring seat (28) and is discharged from the discharge hole (33) to the collection hood (35). At this time, the three-way valve (37) can be opened to sample and test the grinding condition of the mixed adhesive. If it does not meet the requirements, the three-way valve (37) is adjusted to switch the direction, and the circulation pump (39) is started to draw the mixed adhesive through the circulation pipe (38) and transport it to the feed port (4) for grinding again. After the grinding test of the mixed adhesive is qualified, it can be transported to the downstream equipment for flocculation.

[0034] During the grinding process, depending on the grinding requirements, the upper adjustment drive (23) can be activated to move the upper bearing plate (22) up and down to adjust the gap between the lower stationary grinding disc (8) and the lower moving grinding disc (10), and between the upper stationary grinding disc (9) and the upper moving grinding disc (11), thereby adjusting the grinding particle size; or the lower adjustment motor (29) can be activated to move the lower bearing ring seat (28) up and down to adjust the gap between the lower stationary grinding disc (8) and the lower moving grinding disc (10), and between the upper stationary grinding disc (9) and the upper moving grinding disc (11), thereby adjusting the precision, or individually By operating the control part (18) of the lower rotating shaft (7), the lower rotating shaft (7) can be rotated upward or downward to adjust the distance between the lower moving grinding disc (10) and the upper moving grinding disc (11), thereby achieving the purpose of adjusting the gap between the lower stationary grinding disc (8) and the lower moving grinding disc (10) independently. Based on this principle, after adjusting the gap between the upper stationary grinding disc (9) and the upper moving grinding disc (11), the gap between the lower stationary grinding disc (8) and the lower moving grinding disc (10) can be adjusted independently, greatly improving the ease of use, realizing multiple uses of one item, and meeting the grinding needs of different particle sizes.
