Description

Technical Field

[0001] This utility model belongs to the technical field of pressure kneading machines, and particularly relates to a pressure kneading machine with a feeding mechanism to prevent spillage. Background Technology

[0002] A kneading mill, also known as an internal mixer, is an industrial equipment used for the plasticizing and mixing of rubber and plastics. It is mainly used in the tire, seal, cable, and hose industries. Based on its structure, it is divided into two types: pressurized and open. The pressurized type uses an elliptical shearing rotor, the mixing chamber surface is coated to enhance wear resistance, supports steam or cooling water circulation for temperature control, uses cylinder pressurization to improve efficiency, and is equipped with a planetary reducer to reduce noise.

[0003] Existing pressure kneaders are prone to spillage of rubber raw materials during operation due to their small feed inlet. Therefore, we propose a pressure kneader with spillage prevention during feeding. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a pressure kneading machine with spillage prevention during material feeding, thus avoiding the problem of spillage during rubber raw material feeding.

[0005] In view of this, the present invention provides a pressure kneading machine with spill-proof feeding, comprising a base, a feeding motor fixedly connected to the outer wall of the base, a kneading machine body fixedly connected to the output end of the feeding motor, a feeding plate welded to the top of the kneading machine body, a kneading motor fixedly connected to the outer wall of the kneading machine body, a kneading roller fixedly connected to the output end of the kneading motor, a pressure port fixedly connected to the side wall of the kneading machine body, an air pump connected to one end of the pressure port, a sealing frame fixedly connected to the outer wall of the base, and a pneumatic pusher cylinder fixedly connected to the top of the sealing frame. A pressure plate is fixedly connected to the output end of the pneumatic pusher cylinder. A feeding frame is welded to the outer wall of the sealing frame. A servo motor is fixedly connected to the outer wall of the feeding frame. A screw is fixedly connected to the output end of the servo motor. A threaded seat is threadedly connected to the outer wall of the screw. A lifting hole plate is fixedly connected to the outer wall of the threaded seat. A rotating plate is movably connected to the hole of the lifting hole plate. A rotating shaft connected to a bearing on the inner wall of the feeding frame is fixedly connected to one end of the rotating plate. A feeding box is fixedly connected to the outer wall of the rotating shaft. A support block is fixedly connected to the connection between the feeding frame and the feeding box.

[0006] Based on the above structure, the worker pours the rubber raw material into the feeding box. Then, the servo motor drives the lifting plate on the outer wall of the threaded seat to slide along the outer wall of the feeding frame through the screw. The sliding of the lifting plate drives the rotating shaft to rotate through the rotating plate. The rotation of the rotating shaft causes the feeding box to flip, so that the feeding box rotates and drives the rubber raw material into the kneading machine body, realizing the automatic feeding operation of the rubber raw material. Moreover, the shape of the feeding box is an inverted trapezoid to avoid the rubber raw material from spilling during feeding.

[0007] Preferably, the kneading machine body forms a sealed structure between the feeding plate and the feeding frame. The cross-section of the feeding plate is arc-shaped. In this embodiment, the feeding motor drives the kneading machine body to rotate, and the rotation of the kneading machine body drives the feeding plate to rotate synchronously. The kneaded rubber raw material is fed through the feeding plate. By setting the feeding plate with an arc-shaped cross-section, collisions between the feeding plates are avoided.

[0008] Preferably, the sealing frame is perpendicular to the kneading machine body, and the bottom end of the pressure plate is arc-shaped. In this embodiment, the pneumatic pusher cylinder drives the pressure plate to slide vertically along the inner wall of the sealing frame, so that the pressure plate fits against the top of the kneading machine body, thereby achieving the sealing operation of the kneading machine body.

[0009] Preferably, two sets of kneading rollers are provided, and the two sets of kneading rollers are connected by a gearbox. In this embodiment, this facilitates the operation of the kneading motor to drive the kneading rollers to rotate. At the same time, the air pump operates to inject high-pressure gas into the kneading machine body through the pressurization port. The rotation of the kneading rollers drives the rubber raw material to perform a kneading operation.

[0010] Preferably, the rotating shaft forms a rotating structure with the feeding frame through the lifting hole plate and the rotating plate. In this embodiment, the servo motor drives the lifting hole plate on the outer wall of the threaded seat to slide along the outer wall of the feeding frame through the screw. The sliding of the lifting hole plate drives the rotating shaft to rotate through the rotating plate.

[0011] Preferably, the feeding box is in the shape of an inverted trapezoid, and the rotation center of the feeding box coincides with the central axis of the rotating shaft. In this embodiment, the rotation of the rotating shaft drives the feeding box to rotate, so that the feeding box rotates and drives the rubber raw material into the kneading machine body, realizing the automatic feeding operation of the rubber raw material. Moreover, the feeding box is in the shape of an inverted trapezoid to avoid the rubber raw material from spilling during feeding.

[0012] Preferably, the support block is inclined and fits against the outer wall of the feeding box. In this embodiment, by setting the inclined support block, the feeding box is supported, and the rotating shaft is prevented from deforming.

[0013] The beneficial effects of this utility model are:

[0014] 1. This pressure kneading machine with anti-spillage feeding system features a feeding box. Workers pour rubber raw materials into the feeding box, and then a servo motor drives a screw to slide a lifting plate on the outer wall of the threaded seat along the outer wall of the feeding frame. The sliding of the lifting plate drives a rotating shaft to rotate, which in turn rotates the feeding box, causing it to flip and pour the rubber raw materials into the kneading machine body. This achieves automatic feeding of rubber raw materials. Furthermore, the feeding box is trapezoidal in shape to prevent spillage during feeding.

[0015] 2. This pressure kneading machine with spill prevention and feeding system uses a pressure plate. A pneumatic pusher cylinder drives the pressure plate to slide vertically along the inner wall of the sealing frame, so that the pressure plate fits against the top of the kneading machine body, thereby achieving a sealing operation of the kneading machine body. Then, the kneading motor drives the kneading roller to rotate. At the same time, the air pump drives the high-pressure gas to be injected into the kneading machine body through the pressurization port. The rotation of the kneading roller drives the rubber raw material to perform a kneading operation. Attached Figure Description

[0024] This application discloses a pressure kneading machine with spill-proof feeding mechanism, comprising a base 1, a feeding motor 2 fixedly connected to the outer wall of the base 1, a kneading machine body 3 fixedly connected to the output end of the feeding motor 2, a feeding plate 301 welded to the top of the kneading machine body 3, a kneading motor 4 fixedly connected to the outer wall of the kneading machine body 3, a kneading roller 5 fixedly connected to the output end of the kneading motor 4, a pressure port 6 fixedly connected to the side wall of the kneading machine body 3, an air pump 7 connected to one end of the pressure port 6, a sealing frame 8 fixedly connected to the outer wall of the base 1, a pneumatic pusher cylinder 9 fixedly connected to the top of the sealing frame 8, and a pneumatic pusher cylinder 9 fixedly connected to the output end of the pneumatic pusher cylinder 9.

[0025] Based on the above structure, the worker pours the rubber raw material into the feeding box 18. Then, the servo motor 12 drives the lifting plate 15 on the outer wall of the threaded seat 14 to slide along the outer wall of the feeding frame 11 through the screw 13. The sliding of the lifting plate 15 drives the rotating shaft 17 to rotate through the rotating plate 16. The rotation of the rotating shaft 17 causes the feeding box 18 to flip, so that the feeding box 18 rotates and drives the rubber raw material into the kneading machine body 3, realizing the automatic feeding operation of the rubber raw material. Moreover, the shape of the feeding box 18 is an inverted trapezoid to avoid the rubber raw material from spilling during feeding.

[0026] In one embodiment, the kneading machine body 3 forms a sealed structure between the feeding plate 301 and the feeding frame 11, and the cross-section of the feeding plate 301 is arc-shaped.

[0027] In this embodiment, the feeding motor 2 drives the kneading machine body 3 to rotate, and the rotation of the kneading machine body 3 drives the feeding plate 301 to rotate synchronously. The kneaded rubber raw material is fed through the feeding plate 301. By setting the feeding plate 301 with an arc-shaped cross-section, collisions of the feeding plate 301 are avoided.

[0028] In one embodiment, the sealing frame 8 is perpendicular to the kneading machine body 3, and the bottom end of the pressure plate 10 is arc-shaped.

[0030] In one embodiment, two sets of kneading rollers 5 are provided, and the two sets of kneading rollers 5 are connected by a gearbox.

[0031] In this embodiment, the kneading motor 4 drives the kneading roller 5 to rotate, while the air pump 7 injects high-pressure gas into the kneading machine body 3 through the pressurization port 6.

Moreover, the feeding box 18 is in the shape of an inverted trapezoid to avoid the rubber raw material from spilling during feeding.

[0036] In one embodiment, the support block 19 is inclined and fits against the outer wall of the feeding box 18.

[0037] In this embodiment, by setting an inclined support block 19, the feeding box 18 is supported, thus preventing the rotating shaft 17 from deforming.

[0038] In this embodiment of the pressure kneading machine with anti-spillage feeding, the operator first pours the rubber raw material into the feeding box 18. Then, the servo motor 12 drives the lifting plate 15 on the outer wall of the threaded seat 14 to slide along the outer wall of the feeding frame 11 via the screw 13. The sliding of the lifting plate 15 drives the rotating shaft 17 to rotate via the rotating plate 16. The rotation of the rotating shaft 17 causes the feeding box 18 to flip, so that the feeding box 18 rotates and drives the rubber raw material into the kneading machine body 3, realizing the automatic feeding operation of the rubber raw material. Moreover, the shape of the feeding box 18 is an inverted trapezoid to prevent the rubber raw material from spilling during feeding.

[0039] Next, the pneumatic pusher cylinder 9 operates to drive the pressure plate 10 to slide vertically along the inner wall of the sealing frame 8, so that the pressure plate 10 is in contact with the top of the kneading machine body 3, thereby achieving the sealing operation of the kneading machine body 3.

At the same time, the air pump 7 operates to drive high-pressure gas into the kneading machine body 3 through the pressurization port 6.
