Description

Technical Field

[0001] This application relates to the technical field of rubber product manufacturing equipment, specifically a feeding device for a kneader. Background Technology

[0002] Kneaders are ideal equipment for kneading, mixing, vulcanizing, and polymerizing high-viscosity, elasto-plastic materials. Kneaders can be used to produce silicone rubber, sealants, hot melt adhesives, food adhesives, pharmaceutical preparations, etc. Kneaders are a special type of mixing and stirring equipment. The most common type uses two blades arranged in a parallel tangential differential speed configuration, where one blade moves faster and the other moves slower, in order to generate shearing force. The different blade speeds allow the materials to be mixed quickly and evenly.

[0003] An existing patent (publication number: CN212578958U) discloses a feeding device for a kneader, including a kneader body. The feeding port of the kneader body is connected to a fixed cylinder. A protrusion is integrally formed in the middle of the fixed cylinder. A rotating component is attached to the inner wall of the protrusion. A feeding cylinder is connected to the top of the fixed cylinder. A feeding cylinder is welded to the top of the feeding cylinder. Support components are hinged to both sides of the top inner wall of the feeding cylinder. Movable plates are hinged to the bottom of the two sets of support components. Connecting blocks are hinged to the ends of the two sets of movable plates that are far apart from each other. By the reciprocating movement of the movable blocks in the slide rail, the two sets of movable plates can open and close, so that the material on the movable plates can be fed intermittently, thereby reducing the feeding speed of the material and facilitating the subsequent rapid mixing and uniform mixing of the material by the kneader body.

[0004] However, the above-mentioned scheme found that in the production of rubber products, frequent manual adjustment of the amount of material added is not only labor-intensive, but also prone to errors due to human factors, resulting in inconsistent weight of material added each time. The proportion of rubber mixture is crucial to product quality. Without quantitative material addition, it is difficult to ensure that the weight of each batch of material can be controlled, which can easily lead to unstable product performance and an increase in the defect rate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a feeding device for a kneader, which has the advantages of enabling quantitative feeding. This solves the problems of frequent manual adjustments to the feeding amount, which not only consume manpower but are also prone to errors due to human factors, resulting in inconsistent feeding weights each time. Furthermore, the lack of quantitative feeding makes it difficult to ensure that the weight of each batch of feeding can be controlled, which can easily lead to unstable product performance and an increased defect rate.

[0006] To achieve the above objectives, this application provides the following technical solution: a feeding device for a kneader, comprising a kneader body and a telescopic rod, wherein a feeding box is fixedly installed on the upper surface of the kneader body, a mounting frame is fixedly connected to the output end of the telescopic rod, a weighing sensor is fixedly installed on the upper surface of the mounting frame, a carrying plate is installed on the upper surface of the weighing sensor, a scraper is fixedly connected to the inner side wall of the feeding box, and equidistant pads are fixedly connected to the upper surface of the mounting frame, and two sliding blocks are fixedly connected to the bottom surface of the mounting frame.

[0007] To monitor the feeding weight in real time, facilitate quantitative feeding, and improve the accuracy and stability of feeding, the above scheme involves installing a mounting frame inside the feeding hopper and connecting it to a telescopic rod. A weighing sensor is installed above the mounting frame, and a loading plate is positioned above the weighing sensor. The weighing sensor value is pre-set. As material falls from above, the weight on the loading plate slowly increases until it reaches the set value of the weighing sensor. At this point, feeding stops, and the telescopic rod is activated, causing the mounting frame to retract. This, in turn, moves the loading plate. A scraper installed on the inner wall of the feeding hopper pushes the material off the surface of the loading plate as it moves. This allows the device to be set with different values ​​according to different usage conditions, achieving quantitative feeding and improving the accuracy and stability of feeding.

[0008] Furthermore, two sliding rods are fixedly connected to the inner wall of the feed box, and the outer surface of each sliding rod is slidably connected to the inner wall of the corresponding sliding block.

[0009] The above scheme involves installing the sliding block on the bottom surface of the mounting frame and installing the sliding rod on the inner wall of the feed box, forming a fixed connection. The surfaces of the sliding block and the sliding rod are connected, forming a sliding connection. The two sliding rods can support the sliding block.

[0010] Furthermore, a spring is fixedly connected to the right side of each sliding block, and the right end of each spring is fixedly connected to the inner side wall of the feed box.

[0011] With the above solution, the spring is installed on the right side of the sliding block and fixedly connected. The right end of the spring is also connected to the inner wall of the feed box and fixedly connected. When the mounting bracket moves the sliding block, the spring can be slowly compressed and prevent the sliding block from disengaging from the slide rod.

[0012] Furthermore, a fixing frame is fixedly connected to the bottom surface of the telescopic rod, and two limiting blocks are fixedly connected to the upper surface of the fixing frame.

[0013] The above scheme involves installing a fixing frame one on the bottom surface of the telescopic pole as a fixed connection, thereby supporting and limiting the telescopic pole. A limiting block is installed on the upper surface of the fixing frame one as a fixed connection, thus enabling the installation of the limiting block.

[0014] Furthermore, two limiting rods are fixedly connected to the right side of the mounting bracket, and the outer surface of each limiting rod is slidably connected to the inner wall of the corresponding limiting block.

[0015] The above solution involves installing the limiting rod on the right side of the mounting frame as a fixed connection, and connecting the surface of the limiting rod to the corresponding limiting block as a sliding connection. The connection between the limiting block and the limiting rod further enhances the stability of the mounting frame during movement.

[0016] Furthermore, a second fixing frame is fixedly connected to the upper surface of the kneader body, a material bucket is fixedly connected to the inner wall of the second fixing frame, and a feeding pipe is fixedly connected to the bottom end of the material bucket.

[0017] The above scheme involves installing the second fixing frame on the upper surface of the kneader body and setting it as a fixed connection. The material bucket is also installed on the upper surface of the second fixing frame and set as a fixed connection. The second fixing frame supports the material bucket. The feeding pipe is connected to the bottom of the material bucket, and the feeding pipe facilitates the falling of materials.

[0018] Furthermore, a support frame is fixedly installed on the inner wall of the material barrel, and a motor is fixedly connected to the inner wall of the support frame.

[0019] The above solution involves installing the support frame on the inner wall of the material hopper as a fixed connection, and installing the motor on the inner wall of the support frame to achieve support and installation of the motor.

[0020] Furthermore, the output shaft of the motor is fixedly connected to a connecting rod, and an auger is fixedly installed on the outer surface of the connecting rod.

[0021] The above scheme involves mounting the connecting rod on the output shaft of the motor, setting it as a fixed connection. The motor enables the connecting rod to rotate, and an auger is installed on the surface of the connecting rod. The motor drives the connecting rod to rotate, which in turn drives the auger to rotate. The rotation of the auger allows the material to be slowly conveyed downwards.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This type of feeding device for a kneader includes components such as a telescopic rod, a mounting frame, a weighing sensor, and a loading plate. First, the rated value of the weighing sensor is preset. During feeding, the material falls onto the loading plate, causing the weight on the loading plate to slowly increase until it reaches the set value of the weighing sensor, at which point feeding stops. Then, the telescopic rod is activated, causing the mounting frame to move. This, in turn, moves the weighing sensor and the loading plate. A scraper removes material from the surface of the loading plate, allowing the material to fall into the kneader body below, achieving a quantitative feeding effect. A motor drives a connecting rod to rotate, which in turn rotates the auger, enabling the material to be transferred. The auger improves the stability of material transfer.

[0040] This embodiment of a kneader feeding device includes components such as a telescopic rod 3, a mounting frame 4, a weighing sensor 5, and a carrying plate 6. First, the rated value of the weighing sensor 5 is preset. During feeding, the material falls onto the carrying plate 6, causing the weight of the carrying plate 6 to increase slowly until the weight reaches the set value of the weighing sensor 5, at which point feeding stops. Then, the telescopic rod 3 is activated to move the mounting frame 4, which in turn moves the weighing sensor 5 and the carrying plate 6. The scraper 7 scrapes off the material on the surface of the carrying plate 6, allowing the material to fall into the kneader body 1 below, achieving a quantitative feeding effect. The motor 19 drives the connecting rod 20 to rotate, which in turn rotates the auger 21, enabling the material to be transferred. The auger 21 improves the stability of material transfer.

[0041] It should be noted that two round rods are installed on the inner wall of the feed box 2, and the round rods are adapted to the grooves on the bottom surface of the mounting frame 4. The connection between the round rods and the grooves on the bottom surface of the mounting frame 4 can further improve the stability of the mounting frame 4 when it moves. The upper surface of the pad 8 contacts the bottom surface of the carrying plate 6 and can support the carrying plate 6.

[0042] The working principle of the above embodiments is as follows:

[0043] During the feeding operation, firstly, the rated value of the weighing sensor 5 is preset, and the motor 19 is started. The motor 19 drives the connecting rod 20 to rotate, which in turn drives the auger 21 to rotate. Through the cooperation of the auger 21 and the discharge pipe 17, the material inside the hopper 16 is slowly transferred downwards. At this time, the material falls onto the carrying plate 6, causing the weight of the carrying plate 6 to slowly increase until the weight reaches the set value of the weighing sensor 5. The motor 19 then stops operating. Subsequently, the telescopic rod 3 is activated to move the mounting frame 4, thereby allowing... The mounting frame 4 moves the weighing sensor 5 and the carrying plate 6. As the carrying plate 6 moves, the material on its surface is scraped off by the scraper 7, allowing the material to fall into the kneader body 1 below, achieving a quantitative feeding effect. During the movement of the mounting frame 4, the stability of the mounting frame 4 is improved by the connection between the sliding block 10 and the sliding rod 9, and by the connection between the limiting rod 12 and the limiting block 14. After feeding is completed, the carrying plate 6 is reset. When feeding is needed again, the motor 19 is started, and the above operation is repeated.
