Description

Technical Field

[0001] This utility model relates to a discharge structure, specifically, to a continuous anti-clogging discharge structure for a kneader. Background Technology

[0002] A kneader is an ideal piece of equipment for kneading, mixing, vulcanizing, and polymerizing high-viscosity, elasto-plastic materials. It can be used to produce silicone rubber, sealants, hot melt adhesives, food adhesives, pharmaceutical preparations, etc. It is a special mixing and stirring device. Kneaders typically use two irregularly shaped blades arranged in a parallel, tangential, differential speed configuration, where one blade moves at a high speed and the other at a low speed to generate shearing force. The different blade speeds allow the materials to be rapidly sheared, resulting in uniform mixing. After the materials inside the kneader are mixed, a discharge structure is installed near the bottom of the kneader cylinder. The commonly used discharge structure for kneaders is a screw conveyor. The screw conveyor transports the materials using gravity and the friction between the materials and the tank wall. The length of the screw conveyor is usually greater than the length of the kneader cylinder, with one end extending out from the inside of the cylinder. This screw conveyor removes the materials from the inside of the cylinder, resulting in a longer stroke for the screw conveyor.

[0003] When a kneader mixes materials with high viscosity, due to the long stroke of the screw conveyor and the high viscosity of the material, as the screw conveyor removes material from the kneader cylinder, the amount of material entering the screw conveyor gradually decreases. This reduces the compressive pressure between materials, resulting in a decrease in the thrust generated between subsequent materials. Material adheres to the blades of the screw conveyor, leading to a significant amount of residual material within the screw conveyor. This accumulation of material can easily cause blockages in the screw conveyor. During material discharge, the amount of material inside the kneader gradually decreases, and due to the high viscosity, a considerable amount of material adheres to the inner wall of the cylinder, resulting in a large amount of residual material inside the cylinder. Simultaneously, material adheres to the discharge port, easily causing blockages and making it difficult for material inside the cylinder to be discharged. Therefore, we propose a continuous anti-blockage discharge structure for kneaders. Utility Model Content

[0004] The purpose of this invention is to provide a continuous anti-clogging discharge structure for a kneader, in order to solve the problems mentioned in the background art, such as high viscosity materials adhering to the inside of the kneader, making it difficult to clean the materials, and the pusher plate easily causing blockage when pushing the materials.

[0005] To achieve the above objectives, one of the objectives of this utility model is to provide a continuous anti-clogging discharge structure for a kneader, including a cylinder body. The top of the cylinder body is provided with a top cover. A stirring assembly is provided inside the cylinder body for stirring the material inside the cylinder. A side plate is fixedly provided on one side of the cylinder body. Two discharge ports symmetrically opened through the side plate near the bottom are located on the side plate. A pushing mechanism is provided inside the cylinder body to push the material inside the cylinder towards the discharge ports and scrape off material adhering to the inner wall of the cylinder. The side plate furthest from the cylinder body and near the bottom... Two discharge mechanisms are symmetrically arranged in the cylinder, and the positions of the discharge mechanisms correspond to the discharge ports. The pushing mechanism pushes the material through the discharge ports into the interior of the discharge mechanism. The discharge mechanism is used to discharge the material inside the cylinder. The stirring component on the top cover stirs the material inside the cylinder. When the material is stirred, the top cover on the cylinder is removed and the stirring component is removed. Then, the pushing mechanism pushes the material inside the cylinder closer to the discharge port, so that the material passes through the discharge port and enters the interior of the discharge mechanism, so that the discharge mechanism can discharge the material in time and avoid the material from blocking the discharge port.

[0006] As a further improvement to this technical solution, the pushing mechanism includes a pushing plate slidably disposed inside the cylinder. Two electric telescopic rods are symmetrically arranged at the top position of the pushing plate near the side plate. The electric telescopic rods are fixedly disposed on the side of the side plate away from the cylinder. When the piston rod of the electric telescopic rod extends or retracts, it drives the pushing plate to move. The shape of the pushing plate matches the cross-section of the cylinder. The pushing plate slides in contact with the inner wall of the cylinder. After the material is stirred, the piston rod of the electric telescopic rod retracts, driving the pushing plate to move inside the cylinder closer to the discharge mechanism. The moving pushing plate pushes the material toward the discharge mechanism. During the movement, the pushing plate scrapes off the material adhering to the inner wall of the cylinder.

[0007] As a further improvement to this technical solution, the discharge mechanism includes a discharge cylinder fixedly installed on the side plate away from the cylinder body and near the bottom. The discharge cylinder is connected to the inside of the cylinder body through a discharge port. The material inside the cylinder body enters the inside of the discharge cylinder through the discharge port. A discharge pipe is fixedly installed at the bottom of the discharge cylinder away from the cylinder body. A spiral conveying assembly is provided inside the discharge cylinder. The spiral conveying assembly is used to convey the material. A pushing mechanism pushes the material inside the cylinder body through the discharge port into the inside of the discharge cylinder, so that the material flows inside the discharge cylinder and is discharged through the discharge pipe.

[0008] As a further improvement to this technical solution, the screw conveyor assembly includes a drive motor fixedly installed at the end of the discharge cylinder away from the cylinder body. The output shaft of the drive motor extends into the interior of the discharge cylinder and is coaxially connected to an auger shaft via a coupling. Auger blades are fixedly installed on the auger shaft. The output shaft of the drive motor drives the auger shaft to rotate, causing the auger shaft to drive the auger blades to rotate. The rotating auger blades move the material. When the material inside the cylinder enters the interior of the discharge cylinder, the output shaft of the drive motor drives the auger shaft to rotate during rotation. The rotating auger shaft drives the auger blades to rotate, causing the auger blades to move the material inside the discharge cylinder, thereby conveying the material.

[0009] As a further improvement to this technical solution, a baffle plate is slidably provided inside the side plate. The baffle plate is used to seal the discharge port. During the material mixing process, the top cover is installed on the top of the cylinder. At this time, the top of the baffle plate abuts against the top cover to prevent the baffle plate from moving out of the inside of the side plate. The material inside the cylinder is conveyed through the baffle plate to prevent the material from passing through the discharge port and entering the inside of the discharge cylinder.

[0010] As a further improvement to this technical solution, two lifting plates are symmetrically fixed on the top of the pusher plate near the baffle plate. The side of the lifting plate near the baffle plate is inclined. The top of the lifting plate slides in contact with the baffle plate. As the pusher plate moves the lifting plate closer to the baffle plate, the lifting plate causes the baffle plate to rise. As the pusher plate pushes the material, it causes the lifting plate to move towards the baffle plate. During the movement of the lifting plate, the baffle plate slides along the inclined surface of the lifting plate, causing the lifting plate to rise and move the bottom of the baffle plate out of the discharge port, so that the material passes through the discharge port and enters the discharge cylinder.

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

[0012] 1. This kneader features a continuous anti-clogging discharge structure. After the material is mixed, the pushing mechanism pushes the material inside the cylinder towards the discharge port, accelerating the discharge of the material. At the same time, the pushing mechanism drives the baffle plate to rise, causing the bottom of the baffle plate to move out of the discharge port, thus opening the discharge port. The pushing mechanism reciprocates, pushing the material inside the cylinder through the discharge port into the discharge mechanism. Subsequently, the discharge mechanism discharges the material from the inside of the cylinder in a timely manner, thereby preventing the material from accumulating at the discharge port and ensuring the normal flow of the material.

[0025] 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.

[0026] Example 1

[0027] Please see Figure 1 - Figure 8As shown, one of the objectives of this embodiment is to provide a continuous anti-clogging discharge structure for a kneader, including a cylinder 1, a top cover 13 on the top of the cylinder 1, and a stirring assembly inside the cylinder 1. The stirring assembly is used to stir the material inside the cylinder 1. The stirring assembly includes two stirring blades symmetrically and rotatably connected inside the cylinder 1. One end of the stirring blade is externally connected to a stirring motor. The output shaft of the stirring motor is connected to the end of the stirring blade through a coupling. The rotating output shaft of the stirring motor drives the stirring blade to rotate. During the rotation of the stirring blade, the stirring blade stirs the material inside the cylinder 1. A side plate 11 is fixedly provided on one side of the cylinder 1. Two discharge ports are symmetrically opened near the bottom of the side plate 11, penetrating the side plate 11. A baffle plate 12 is slidably provided inside the side plate 11. The baffle plate 12 is used to seal the discharge ports to prevent the material from passing through the discharge ports from the inside of the cylinder 1 during the stirring process.

[0028] Workers place materials into the cylinder 1, then use mechanical equipment to move the top cover 13 and place it over the top of the cylinder 1. At this time, the output shaft of the stirring motor rotates, driving the stirring blades to rotate, causing the stirring blades to stir the materials inside the cylinder 1. Simultaneously, the top of the baffle plate 12 abuts against the top cover 13 on the top of the cylinder 1, fixing the baffle plate 12 inside the side plate 11 through the top cover 13, so that the bottom of the baffle plate 12 is located inside the discharge port. The baffle plate 12 seals the discharge port to prevent materials from being discharged from the inside of the cylinder 1 through the discharge port. After the materials inside the cylinder 1 are stirred, workers use mechanical equipment to remove the top cover 13 from the cylinder 1. Then, workers lift the baffle plate 12, so that the bottom of the baffle plate 12 moves out from inside the discharge port. At this time, the discharge port is no longer blocked by the baffle plate 12, and the materials inside the cylinder 1 are discharged through the discharge port.

[0029] During the discharge of material from inside cylinder 1, materials with higher fluidity are preferentially discharged from inside cylinder 1, reducing the fluidity of the remaining material inside cylinder 1. This causes a decrease in the speed at which the material passes through the discharge port, making it prone to blockage at the discharge port and affecting the discharge of subsequent materials. To avoid blockage of material inside cylinder 1 during the discharge process, refer to... Figure 1 - Figure 3The cylinder body 1 is equipped with a pushing mechanism 2 inside. The pushing mechanism 2 pushes the material inside the cylinder body 1 towards the discharge port and scrapes off the material adhering to the inner wall of the cylinder body 1. The pushing mechanism 2 includes a pushing plate 22 slidably disposed inside the cylinder body 1. Two electric telescopic rods 21 are symmetrically arranged at the top position of the pushing plate 22 near the side plate 11. The electric telescopic rods 21 are fixedly disposed on the side of the side plate 11 away from the cylinder body 1. When the piston rod of the electric telescopic rod 21 extends or retracts, it drives the pushing plate 22 to move. The shape of the pushing plate 22 matches the cross-section of the cylinder body 1. The pushing plate 22 slides in contact with the inner wall of the cylinder body 1. At the same time, the pushing plate 22 has an opening that penetrates through the pushing plate 22. The size of the opening is larger than the space required for the rotation of the two stirring blades, so that the pushing plate 22 can move outside the stirring blades and avoid the stirring blades affecting the movement of the pushing plate 22. Two lifting plates 23 are symmetrically fixedly installed on the top of the material plate 22 near the baffle plate 12. The side of the lifting plate 23 near the baffle plate 12 is inclined downwards. The top of the lifting plate 23 slides in contact with the baffle plate 12. The side plate 11 has a movable groove inside. The baffle plate 12 is slidably installed inside the movable groove and can slide up and down in the movable groove. Two moving grooves are symmetrically opened on both sides of the side plate 11 near the top. The moving grooves are connected to the movable grooves and correspond to the position of the lifting plate 23. The end of the lifting plate 23 away from the push plate 22 slides through the moving groove. The shape of the moving groove matches that of the lifting plate 23. Several guide rails are fixedly installed on the inner wall of the cylinder 1. The push plate 22 is slidably installed on the guide rails and moves along the axis of the guide rails.

[0030] When it is necessary to discharge the material inside cylinder 1, the piston rod of the electric telescopic rod 21 retracts, causing the pusher plate 22 to move towards the discharge port. The moving pusher plate 22 pushes the material inside cylinder 1 closer to the discharge port. Simultaneously, as the pusher plate 22 moves, it also moves the lifting plate 23 closer to the baffle plate 12. One end of the lifting plate 23 inserts into the movable groove, and the inclined end of the lifting plate 23 contacts the lower side wall of the baffle plate 12. Through the restriction of the baffle plate 12 by the side plate 11, the baffle plate 12 slides and rises along the inclined surface of the lifting plate 23. At this time, the bottom of the baffle plate 12 moves out from inside the discharge port, the discharge port is opened, and the material in cylinder 1 flows towards the discharge port.

[0031] At the same time, when the pusher plate 22 moves, it pushes the material in the cylinder 1 toward the discharge port, speeding up the material flow and preventing the material from getting stuck at the discharge port. Meanwhile, the electric telescopic rod 21 drives the pusher plate 22 to move back and forth inside the cylinder 1. When the pusher plate 22 moves, the horizontal section of the lifting plate 23 slides in the moving groove, so that the bottom of the baffle plate 12 will not block the discharge port, ensuring the normal discharge of the material. During the reciprocating movement of the pusher plate 22, the material inside the cylinder 1 is quickly discharged, thereby reducing the material inside the cylinder 1.

[0032] After the material inside the cylinder 1 is discharged, the piston rod of the electric telescopic rod 21 extends and drives the pusher plate 22 to move away from the side plate 11, so that the pusher plate 22 contacts the side of the cylinder 1 away from the side plate 11. During the movement, the pusher plate 22 works with the cylinder 1 to squeeze the material. The material flows through the opening to the side of the pusher plate 22 near the side plate 11. Then the piston rod of the electric telescopic rod 21 retracts and drives the pusher plate 22 to move closer to the side plate 11. During the movement, the pusher plate 22 scrapes off the material adhering to the inner wall of the cylinder 1 and pushes the scraped material into the discharge port, thereby reducing the material residue inside the cylinder 1 and facilitating subsequent cleaning of the inside of the cylinder 1 by the staff.

[0033] Example 2

[0034] refer to Figure 4 and Figure 5 Two discharge mechanisms 3 are symmetrically arranged on the side plate 11 away from the cylinder 1 and near the bottom. The discharge mechanism 3 is positioned opposite the discharge port. The material pushed by the pushing mechanism 2 enters the discharge mechanism 3 through the discharge port. The discharge mechanism 3 is used to discharge the material inside the cylinder 1. The discharge mechanism 3 includes a discharge cylinder 31 fixedly arranged on the side plate 11 away from the cylinder 1 and near the bottom. The discharge cylinder 31 is connected to the inside of the cylinder 1 through the discharge port. The material inside the cylinder 1 enters the discharge cylinder 31 through the discharge port. A discharge pipe is fixedly arranged at the bottom of the discharge cylinder 31 away from the cylinder 1. The discharge cylinder 31 is equipped with a screw conveyor assembly. The screw conveyor assembly is used to convey the material. The material is pushed into the discharge cylinder 31 by the pushing mechanism 2, so that the material passes through the discharge port and enters the discharge cylinder 31. At this time, the screw conveyor assembly inside the discharge cylinder 31 drives the material to move, so that the material moves away from the discharge port quickly, thereby avoiding the material accumulation at the discharge port and causing material blockage. At the same time, it shortens the stroke distance of the screw conveyor assembly, so that less material remains on the screw conveyor assembly.

[0035] refer to Figure 4 and Figure 5The screw conveyor assembly includes a drive motor 32 fixedly installed at the end of the discharge cylinder 31 away from the cylinder 1. The output shaft of the drive motor 32 extends into the interior of the discharge cylinder 31 and is coaxially connected to an auger shaft 33 via a coupling. An auger blade 34 is fixedly installed on the auger shaft 33. The output shaft of the drive motor 32 drives the auger shaft 33 to rotate, causing the auger shaft 33 to drive the auger blade 34 to rotate. The rotating auger blade 34 conveys the material to a position close to the discharge pipe, allowing the material to pass through the discharge pipe and be discharged from the interior of the discharge cylinder 31. A cover plate is rotatably installed on the top of the discharge cylinder 31. The operator opens the cover plate to clean the material remaining inside the discharge cylinder 31.

[0036] When using this device:

[0037] The moving pusher plate 22 pushes the material through the discharge port into the discharge cylinder 31. After the material enters the discharge cylinder 31, the output shaft of the drive motor 32 drives the auger shaft 33 to rotate. During the rotation of the auger shaft 33, the auger blades 34 rotate, causing the auger blades 34 to transport the material from the end of the discharge cylinder 31 near the cylinder 1 to the end away from the cylinder 1. Then the material passes through the discharge pipe and is discharged from the discharge cylinder 31, thereby accelerating the uniform flow of the material and avoiding material splashing at the discharge port when the pusher plate 22 pushes the material, ensuring the stable flow of the material. At the same time, the discharge mechanism 3 discharges the material from the inside of the cylinder 1 in a timely manner, thereby preventing the material from accumulating at the discharge port and ensuring the normal flow of the material.
