Description

Technical Field

[0001] This utility model relates to the technical field of rubber adhesive production equipment, specifically a screening and mixing device for rubber adhesive (RA) production. Background Technology

[0002] Rubber adhesive RA is a solid methylene donor adhesive composed of hexamethoxymethylmelamine as the main component and inorganic or organic carrier. It is widely used in the rubber industry for bonding rubber with reinforcing materials such as steel wire, nylon, polyester, rayon, and glass fiber. It plays a key role, especially in the manufacture of rubber products such as tires, conveyor belts, hoses, and rubber sheets.

[0003] In the production process of rubber adhesive (RA), the screening and mixing of raw materials are key steps. Traditional screening and mixing equipment often has limited functions, poor screening effect, and uneven mixing, resulting in unstable quality of the produced rubber adhesive and low production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a screening and mixing device for the production of rubber adhesives (RA) to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a screening and mixing device for the production of rubber adhesive RA, including a mixing mechanism, screening mechanisms are provided on both the left and right sides of the mixing mechanism, and an anti-slip mechanism is provided at the bottom of the mixing mechanism;

[0006] The mixing mechanism includes a base plate, a support plate fixedly connected to the top of the base plate, a mixing tank fixedly connected to the top of the support plate, a rotating rod rotatably connected inside the mixing tank, a spiral stirring blade fixedly connected to the surface of the rotating rod, a motor fixedly connected to the front end of the rotating rod, a feeding frame fixedly connected to the top of the mixing tank, and a filter screen fixedly connected to the inner wall of the feeding frame.

[0007] The screening mechanism includes a connecting bracket, a connecting plate and a first connecting seat are fixedly connected to the inner side of the connecting bracket, a guide frame is fixedly connected to the top of the connecting plate, a screen is slidably connected to the top of the guide frame, a second connecting seat is fixedly connected to the right side of the screen, and an electric push rod is hinged to the first connecting seat.

[0008] Preferably, the motor is fixedly connected to the front end of the mixing tank, and a discharge pipe is fixedly connected to the rear of the mixing tank, with a switch valve installed inside the discharge pipe.

[0009] Furthermore, the motor is fixedly installed at the front end of the mixing tank. The relatively fixed installation position of the motor provides a stable structural foundation for the subsequent rotation of the rotating rod by the motor. A discharge pipe is fixedly connected to the rear of the mixing tank. The function of the discharge pipe is to discharge the rubber adhesive RA after mixing in the mixing tank. A switch valve is installed in the discharge pipe. The switch valve can control the opening and closing of the discharge pipe, thereby flexibly controlling the timing and amount of discharge of the rubber adhesive RA according to actual production needs.

[0010] Preferably, there are two connecting brackets, which are fixedly connected to the left and right sides of the base plate respectively.

[0011] Furthermore, the two connecting brackets are fixedly connected to the left and right sides of the base plate respectively, so that the screening mechanism can be evenly distributed on both sides of the base plate, which is conducive to the overall balance and stable operation of the device.

[0012] Preferably, the output end of the electric push rod is hinged to the second connecting seat, and the screening mechanism is provided with two sets located on the left and right sides of the base plate respectively.

[0013] Furthermore, the connection between the output end of the electric push rod and the second connecting seat is a hinge. The hinged connection has a certain degree of mobility. When the electric push rod extends or retracts, it can drive the screen that is hinged to it to slide on the top of the guide frame, thereby realizing the vibration screening function of the screen. There are two sets of screening mechanisms, which are located on the left and right sides of the bottom plate, respectively. This allows the device to screen the raw materials entering from both sides at the same time, improving the screening efficiency. It also corresponds to the overall structural layout of the mixing mechanism, which has screening mechanisms on both the left and right sides.

[0014] Preferably, each of the two guide frames has a groove at its top, and the bottom of each of the two screens is slidably connected in the groove at the top of the two guide frames, with the bottom of each screen overlapping the front and rear ends of the top of the feed frame.

[0015] Furthermore, both guide frames are equipped with grooves at their tops. These grooves provide a track for the screen to slide, ensuring that the screen can slide stably in a predetermined direction under the drive of the electric push rod. The bottoms of the two screens are slidably connected to the grooves at the tops of the two guide frames. This connection method allows the screen to vibrate regularly under the constraint of the guide frames, thereby achieving effective screening of the raw materials. The bottoms of the two screens overlap with the front and rear ends of the top of the feed frame, respectively. This overlap allows the screened raw materials to fall smoothly from the screens into the feed frame and then into the mixing tank for mixing, ensuring the smooth material conveying of the entire screening and mixing device.

[0016] Preferably, the anti-slip mechanism includes an anti-slip block, and the bottom of the anti-slip block has a plurality of anti-slip grooves evenly distributed.

[0017] Preferably, the anti-slip block is fixedly connected to the bottom of the base plate.

[0018] Furthermore, the anti-slip block is installed at the bottom of the base plate. This layout allows the anti-slip block to directly contact the ground, fully exerting its anti-slip function and ensuring the stability of the device during operation.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0020] First, this utility model places the rubber adhesive RA raw material to be screened into the screens on the left and right sides respectively. The electric push rod is activated, and its output end is hinged to the second connecting seat. As the electric push rod extends and retracts, it drives the screen to slide left and right in the groove at the top of the guide frame, achieving reciprocating motion of the screen to screen the raw material. The qualified raw material after screening falls through the screen into the feed frame. After being filtered again by the filter screen, it enters the mixing tank. After all the raw material enters the mixing tank, the motor is activated, driving the rotating rod to rotate. The spiral stirring blades fixedly connected to the rotating rod rotate accordingly, thoroughly mixing the raw material in the mixing tank. After mixing, the valve in the discharge pipe is opened, discharging the mixed rubber adhesive RA from the discharge pipe for subsequent processing. The screening mechanism first screens the raw material to remove impurities and unqualified particles, and the mixing mechanism then evenly mixes the qualified raw material. This entire process from raw material processing to mixing ensures the quality of the rubber adhesive RA. The high-efficiency screening mechanism and the stable mixing mechanism work together to improve production quality, reduce production delays caused by raw material issues, accelerate the production pace, and improve overall production efficiency.

[0021] Secondly, this utility model places the screening and mixing device for producing rubber adhesive RA in a suitable working position to ensure the stability of the device and the contact between the anti-slip block and the ground. Multiple anti-slip grooves on the bottom of the anti-slip block increase the friction with the ground and prevent the device from sliding during operation. Attached Figure Description

[0028] Example 1

[0030] The mixing mechanism 1 includes a base plate 101, a support plate 102 fixedly connected to the top of the base plate 101, a mixing tank 103 fixedly connected to the top of the support plate 102, a rotating rod 104 rotatably connected inside the mixing tank 103, a spiral stirring blade 105 fixedly connected to the surface of the rotating rod 104, a motor 106 fixedly connected to the front end of the rotating rod 104, a feeding frame 107 fixedly connected to the top of the mixing tank 103, and a filter screen 108 fixedly connected to the inner wall of the feeding frame 107.

[0031] The screening mechanism 2 includes a connecting bracket 201. A connecting plate 202 and a first connecting seat 203 are fixedly connected to the inner side of the connecting bracket 201.

[0033] Specifically, there are two connecting brackets 201, which are fixedly connected to the left and right sides of the base plate 101 respectively.

[0034] Specifically, the output end of the electric push rod 207 is hinged to the second connecting seat 206, and the screening mechanism 2 is provided with two sets located on the left and right sides of the bottom plate 101 respectively.

[0036] Using the above technical solution, the rubber adhesive RA raw material to be screened is placed in the screens 205 on the left and right sides respectively. The internal wiring connections of the electric push rod 207 and the motor 106 are existing technologies and will not be described in detail here. The electric push rod 207 is activated, and its output end is hinged to the second connecting seat 206. As the electric push rod 207 extends and retracts, it drives the screen 205 to slide left and right in the groove opened at the top of the guide frame 204, realizing the reciprocating motion of the screen 205 to screen the raw material. The qualified raw material after screening falls into the feed frame 107 through the screen 205 and is then filtered again by the filter screen 108. The raw materials enter the mixing tank 103. After all the raw materials have entered the mixing tank 103, the motor 106 is started. The motor 106 drives the rotating rod 104 to rotate, and the spiral stirring blades 105 fixedly connected to the surface of the rotating rod 104 rotate accordingly, thoroughly mixing the raw materials in the mixing tank 103. After mixing is completed, the switch valve 110 in the discharge pipe 109 is opened, and the mixed rubber adhesive RA is discharged from the discharge pipe 109 for subsequent production processing. The screening mechanism 2 first screens the raw materials to remove impurities and unqualified particles, and the mixing mechanism 1 then uniformly mixes the qualified raw materials. The entire process from raw material processing to mixing ensures the production quality of rubber adhesive RA. The efficient screening of the screening mechanism 2 and the stable mixing of the mixing mechanism 1 work together to reduce production delays caused by raw material problems, speed up the production pace, and improve overall production efficiency.

The anti-slip block 301 is in contact with the ground, and the multiple anti-slip grooves at the bottom of the anti-slip block 301 increase the friction with the ground to prevent the device from sliding during operation.
