Description

Technical Field

[0002] Rubber is an elastic polymer. Rubber raw materials are processed into elastic high molecular compounds. Rubber products are widely used in industry and life due to their special properties such as insulation, impermeability to water and air.

[0003] In rubber production, rubber raw materials and additives need to be mixed in a certain proportion before reacting and synthesizing. However, due to the different shapes and sizes of the raw materials, the size problem leads to different reaction rates in different areas in the later synthesis, which affects the uniformity of the synthetic product and reduces the quality of the finished rubber. At the same time, during the raw material transportation process, fine particles of raw materials will adhere to the inner wall of the feeding equipment, which not only requires intermittent shutdown for equipment cleaning, but also has a significant impact on the rubber production formula.

[0019] The present invention also provides a feeding process for rubber production, comprising the following steps:

[0020] S1. Put the rubber raw material into the feed hopper, and the raw material is guided through the connecting pipe, the hose and the guide pipe, and enters the inner cavity of the mesh screen tube through the feed port;

[0021] S2, start the motor, the motor drives the driving gear to rotate, the driving gear meshes with the driving ring to rotate and drives the driving sleeve to rotate continuously, at this time the driving block is located in the driving groove, the driving block and the driving groove are engaged to drive the driving pipe body to rotate synchronously, thereby driving the mesh screen tube to rotate, and the rubber raw materials in the mesh screen tube are screened;

[0022] When the driving tube body rotates, the support rod is located in the limit groove, and the driving block is always located in the driving groove through the supporting effect of the support rod on the limit groove, thereby ensuring the smooth rotation of the mesh screen tube. When the support rod moves into the driving groove, the support rod moves along the driving groove, the mesh screen tube loses the support of the support rod, and the inclined mesh screen tube moves toward the fixed disk under the action of gravity and abuts against the support rod again. At this time, the driving block moves from the driving groove to the avoidance ring groove, and the lock of the driving tube body is released, and the mesh screen tube stops rotating. When the support rod moves out of the driving groove, the support rod pushes the driving tube body to move in the direction away from the fixed disk, and the driving block moves from the avoidance ring groove to the driving groove to drive the driving tube body to rotate again. At this time, the mesh screen tube continues to rotate, thereby driving the mesh screen tube to perform a periodic motion alternating between rotation and reciprocating movement.

[0023] The rotation of the mesh screen tube causes the first wedge-shaped tooth plate to engage with the second wedge-shaped tooth plate, and the friction force causes the paddle plate to pull the spring spring to deform and rotate synchronously with the mesh screen tube. When the paddle plate rotates to position A, which is one-third of the height from the top of the mesh screen tube, the tension generated by the deformed spring causes the second wedge-shaped tooth plate to separate from the first wedge-shaped tooth plate and pull the paddle plate to swing in the same direction. When the paddle plate swings in the opposite direction to position B, which is longitudinally symmetrical to position A, it engages with the first wedge-shaped tooth plate that rotates continuously with the mesh screen tube again, thereby driving the paddle plate to swing back and forth in the circumferential direction in the inner cavity of the mesh screen tube.

[0024] S3. The rubber raw material is screened through the mesh screen tube and enters the inner cavity of the conveying pipe body. The mesh screen tube drives the driving spiral plate to rotate. The rotating driving spiral plate cooperates with the inner wall of the conveying pipe body to transport the screened rubber raw material to the discharge pipe, thereby completing the loading of the rubber raw material.

[0025] Beneficial Effects

[0026] The present invention provides a feeding device and a feeding process for rubber production, which have the following beneficial effects:

[0027] The present invention provides a conveying mechanism, and the rubber raw material is conveyed to the inside of the mesh screen tube. The driving block is engaged with the driving groove, and the driving sleeve rotates. The rotating mesh screen tube accelerates the rubber raw material to pass through the mesh screen tube sieve holes and enter the inner cavity of the conveying tube body. At the same time, the driving spiral plate that rotates with the mesh screen tube cooperates with the inner wall of the conveying tube body to convey the screened raw material to the discharge pipe to complete the loading.

[0028] Moreover, by setting a driving ring, the support rod moves along the bottom of the limiting groove to support the driving ring, so that the driving block is located in the driving groove, and the two are kept engaged with each other, so that the mesh screen tube rotates with the driving sleeve; when the support rod moves to the driving groove, the sleeve that has lost the support of the support rod moves in the direction close to the fixed disk, and the driving block moves from the driving groove to the avoiding ring groove, and the sleeve stops rotating; when the support rod moves from the driving groove to the limiting groove, the sleeve is pushed to move in the direction away from the fixed disk, and at the same time, the driving block moves from the avoiding ring groove to the inside of the driving groove, and drives the sleeve to rotate again, so that the mesh screen tube realizes a cyclical motion of alternating rotation and movement, thereby improving the screening efficiency; and when moving, the driving spiral plate on the outer wall of the mesh screen tube cleans the inner wall of the conveying tube body, reducing the deposition of fine particles on the inner wall of the conveying tube body.

[0047] An embodiment of the present invention provides a feeding device for rubber production, including a device body 1 and a conveying mechanism 2, wherein the device body 1 also includes a driving mechanism 3 and a feeding assembly 4, and the conveying mechanism 2 includes a coaxially arranged screening assembly 5, a material shifting assembly 6 and a conveying pipe 7.

[0048] See also Figure 1 - Figure 3The feeding assembly 4 is arranged on the top of the equipment body 1, and the driving mechanism 3 is arranged in the inner cavity of the equipment body 1 to drive the screening assembly 5 to perform a periodic motion of alternating rotation and movement. The conveying pipe 7 is fixedly connected to the side wall of the equipment body 1 at a certain inclination angle. The screening assembly 5 is rotatably connected to the side wall of the conveying pipe 7, and the screening assembly 5 can move along the axial direction. The material-pickup assembly 6 is installed in the inner cavity of the screening assembly 5 and reciprocates in the inner cavity of the screening assembly 5. The rubber raw material is thrown into the inner cavity of the screening assembly 5 through the feeding assembly 4. The screening assembly 5 that performs periodic rotation and movement alternating motion screens the raw material of the indicated particle size into the inner cavity of the conveying pipe 7. At the same time, the rotating screening assembly 5 is transported to the discharging end for loading. The material-pickup assembly 6 reciprocates in the screening assembly 5 to pry the raw material, promotes the raw material to pass through the screen, and cleans the screen to avoid clogging of the screen holes.

[0049] Refer to Figure 4 and the feed assembly Figure 5 The driving mechanism 3 includes a motor 31 installed on the side wall of the equipment body 1 and a driving sleeve 35 rotatably connected to the front end surface of the equipment body 1. The output end of the motor 31 is fixedly connected to a driving gear 32. The driving sleeve 35 is located on the outer wall of the inner cavity of the equipment body 1 and is fixedly connected to a driving ring 33. A plurality of groups of driving blocks 34 are fixedly connected to the inner wall of the driving sleeve 35 at intervals in the circumferential direction. The driving gear 32 partially extends into the inner cavity of the equipment body 1 and meshes with the driving ring 33. The motor 31 works by meshing the driving gear 32 with the driving ring 33 to drive the driving sleeve 35 to rotate; the feeding assembly 4 includes a feeding hopper 41 fixedly connected to the top of the equipment body 1. The feeding hopper 4 The lower end of the connecting pipe 42 extends to the inner cavity of the equipment body 1 and is fixedly connected to the connecting pipe 42. The outlet end of the connecting pipe 42 is fixedly connected to the hose 43. The end of the hose 43 away from the connecting pipe 42 extends to the driving sleeve 35 and is fixedly connected to the guide pipe 47. The end of the guide pipe 47 away from the hose 43 extends to the inner cavity of the screening component 5 and is provided with a feed port 46. The outer wall of the guide pipe 47 is fixedly connected to a fixed plate 44. The side of the fixed plate 44 close to the feed port 46 is fixedly connected to a support rod 45 along the axis. The rubber raw material is fed into the feed hopper 41, guided by the connecting pipe 42, the hose 43 and the guide pipe 47, and passes through the feed port 46 to enter the inner cavity of the screening component 5 for feeding.

[0050] See also Figures 6 to 9 The screening assembly 5 includes a mesh screen tube 53, the inner wall of which is fixedly connected to a first wedge-shaped tooth plate 54, the first wedge-shaped tooth plate 54 is arranged parallel to the axis of the mesh screen tube 53, one end of the mesh screen tube 53 extends into the driving sleeve 35 and is fixedly connected to a driving ring 52, the outer wall of the mesh screen tube 53 is fixedly connected to a driving spiral plate 51, the outer wall of the driving spiral plate 51 is in contact with the inner wall of the conveying pipe 7, and after the rubber raw material passes through the mesh screen tube 53 and is screened, it is conveyed to the feeding place by the rotating driving spiral plate 51.

[0051] Specifically, the driving ring 52 includes a sleeve 521, and a limiting groove 522 is provided on the side of the sleeve 521 close to the driving sleeve 35 with the axis of the sleeve 521 as the center of the circle, and a driving groove 523 is provided at the bottom of the limiting groove 522. The sleeve 521 includes a driving tube body 5211, and a plurality of groups of driving grooves 5212 are spaced apart on the side wall of the driving tube body 5211. Avoidance ring grooves 5213 are provided on the side of the plurality of driving grooves 5212 away from the limiting grooves 522. The inner diameter of the avoidance ring groove 5213 is equal to the inner diameter of the driving groove 5212, and the plurality of driving grooves 5212 are connected to the plurality of driving grooves 5212 at the same time.

[0052] It should be added that the number and shape of the driving grooves 5212 are the same as the number and shape of the driving blocks 34, and the length of the driving blocks 34 along the axial direction is equal to the depth difference between the driving groove 523 and the limiting groove 522, and the avoidance ring groove 5213 and the driving groove 5212 are equal in length along the axial direction.

[0053] It can be understood that when the support rod 45 is located in the limiting groove 522, the driving block 34 is located in the driving groove 5212, and the sleeve 521 is fixedly connected to the driving sleeve 35 through the engagement of the driving block 34 with the driving groove 5212. At this time, the mesh screen tube 53 rotates synchronously with the driving sleeve 35 to screen and transport the raw materials. When the support rod 45 moves to the range of the driving groove 523, the driving ring 52 that loses the contact with the support rod 45 moves along the axis toward the fixed disk 44 due to the action of gravity until the driving groove The bottom of 523 abuts against the support rod 45 again, and the driving block 34 moves into the avoidance ring groove 5213, the driving tube body 5211 is separated from the driving sleeve 35, and the mesh screen tube 53 stops rotating. When the support rod 45 moves along the bottom of the driving groove 523 to the bottom of the limiting groove 522, the driving ring 52 is pushed to move away from the fixed plate 44 again. At the same time, the driving block 34 moves from the avoidance ring groove 5213 to the driving groove 5212, the sleeve 521 is engaged with the driving sleeve 35, and the mesh screen tube 53 rotates with the driving sleeve 35. Thus, the mesh screen tube 53 realizes the alternating periodic motion of rotating and reciprocating.

[0054] It should be noted that the junction between the driving groove 523 and the limiting groove 522 is excessively inclined to avoid jamming of the support rod 45 during movement. At the same time, the covering angle of the driving groove 523 is an integer multiple of the angle between two adjacent groups of driving grooves 5212, that is, when the support rod 45 moves from the bottom of the driving groove 523 to the bottom of the limiting groove 522, the driving block 34 and the driving groove 5212 are located in the same straight line.

[0055] See also Figure 10 to Figure 11The material-selecting assembly 6 includes a mounting shaft 63 whose two ends are respectively fixedly connected to the inner wall of the conveying pipe 7 and the front end surface of the material-guiding pipe 47; the outer wall of the mounting shaft 63 is rotatably connected to a mounting sleeve 62; a selector plate 61 is radially fixedly connected to the outer wall of the mounting sleeve 62; a spring 64 is installed on the outer wall of the mounting shaft 63; the output end of the spring 64 is fixedly connected to the inner wall of the mounting sleeve 62; when the selector plate 61 is selected, the selector plate 61 drives the mounting sleeve 62 to rotate by stretching the spring 64; when the selector plate 61 is released, the tightened spring 64 drives the mounting sleeve 62 to rotate in the opposite direction to the origin.

[0056] Specifically, a second wedge-shaped tooth plate 65 is fixedly connected to the side of the paddle plate 61 facing away from the mounting sleeve 62 . The second wedge-shaped tooth plate 65 and the first wedge-shaped tooth plate 54 match each other in external shape. Meanwhile, the outer wall of the paddle plate 61 fits the inner wall of the mesh tube 53 .

[0057] It can be understood that the first wedge-shaped tooth plate 54 rotating with the mesh tube 53 moves to the outer end of the paddle plate 61 located at the origin position and fits with the second wedge-shaped tooth plate 65. The friction force F between the two causes the paddle plate 61 to rotate with the mesh tube 53 to a certain height A. At this time, the tension generated by the tightened spring 64 is greater than the friction force F. The second wedge-shaped tooth plate 65 separates from the first wedge-shaped tooth plate 54 and pulls the paddle plate 61 to move in the opposite direction. When the second wedge-shaped tooth plate 65 moves to position B, it fits with the first wedge-shaped tooth plate 54 rotating with the mesh tube 53 again, so that the paddle plate 61 swings back and forth in the inner cavity of the mesh tube 53, cleaning the inner wall of the mesh tube 53 while moving the raw materials, thereby improving the screening efficiency.

[0058] It should be noted that by changing the friction force F and the elastic coefficient of the clockwork spring 64, positions A and B can be symmetrically set at the inner wall one-third of the height from the top of the mesh tube 53 to avoid the rubber material in the mesh tube 53 affecting the engagement of the second wedge-shaped tooth plate 65 and the first wedge-shaped tooth plate 54.

[0059] It should also be noted that the length of the shift plate 61 along the axial direction is less than the length of the first wedge-shaped tooth plate 54. When the first wedge-shaped tooth plate 54 moves back and forth following the mesh screen tube 53, the second wedge-shaped tooth plate 65 moves along the axial direction on the outer wall of the first wedge-shaped tooth plate 54 to clean the outer wall of the first wedge-shaped tooth plate 54.

[0060] See also Fig.12 The conveying pipe 7 includes a conveying pipe body 71 fixedly connected to the side wall of the equipment main body 1, and a discharge pipe 73 is fixedly connected to the outer wall of the conveying pipe body 71 at one end away from the equipment main body 1. The discharge pipe 73 is connected to the feed port of the equipment that needs to be loaded. The outer wall of the conveying pipe body 71 is fixedly connected to a support leg 72, which supports the conveying pipe body 71 to improve the stability of loading.

[0061] It should be added that the inner wall of the conveying tube body 71 is in contact with the outer edge of the driving spiral plate 51. When the mesh tube 53 rotates, the driving spiral plate 51 rotates to cause the material to be spirally transported along the inner wall of the conveying tube body 71 to the discharge pipe 73. When the mesh tube 53 moves back and forth, the outer edge of the driving spiral plate 51 moves along the inner wall of the conveying tube body 71 to clean the inner wall of the conveying tube body 71, thereby reducing the adhesion and accumulation of fine particles.

[0062] This embodiment also provides a rubber production feeding process, comprising the following steps:

[0063] S1. Put the rubber raw material into the feed hopper 41. The raw material is guided through the connecting pipe 42, the hose 43 and the guide pipe 47, and passes through the feed port 46 into the inner cavity of the mesh tube 53;

[0064] S2, start the motor 31, the motor 31 drives the driving gear 32 to rotate, the driving gear 32 engages the driving ring 33 to rotate and drives the driving sleeve 35 to rotate continuously, at this time the driving block 34 is located in the driving groove 5212, the driving block 34 is engaged with the driving groove 5212 to drive the driving tube body 5211 to rotate synchronously, thereby driving the mesh screen tube 53 to rotate, and the rubber raw material in the mesh screen tube 53 is screened;

[0065] When the driving tube body 5211 rotates, the support rod 45 is located in the limiting groove 522. The supporting effect of the support rod 45 on the limiting groove 522 makes the driving block 34 always located in the driving groove 5212, thereby ensuring the smooth rotation of the mesh screen tube 53. When the support rod 45 moves into the driving groove 523, the support rod 45 moves along the driving groove 523, and the mesh screen tube 53 loses the support of the support rod 45. The inclined mesh screen tube 53 moves toward the direction close to the fixed plate 44 under the action of gravity and abuts against the support rod 45 again. The moving block 34 moves from the driving groove 5212 to the avoidance ring groove 5213, unlocking the driving tube body 5211, and the mesh tube 53 stops rotating. When the support rod 45 moves out of the driving groove 523, the support rod 45 pushes the driving tube body 5211 to move away from the fixed plate 44, and the driving block 34 moves from the avoidance ring groove 5213 to the driving groove 5212 to drive the driving tube body 5211 to rotate again. At this time, the mesh tube 53 continues to rotate, thereby driving the mesh tube 53 to perform a periodic motion of alternating rotation and reciprocating movement.

[0066] The mesh tube 53 rotates so that the first wedge-shaped tooth plate 54 engages with the second wedge-shaped tooth plate 65, and the friction force causes the paddle plate 61 to pull the spring spring 64 to deform and rotate synchronously with the mesh tube 53. When the paddle plate 61 rotates to a position A that is one-third of the height from the top of the mesh tube 53, the tension generated by the deformed spring spring 64 causes the second wedge-shaped tooth plate 65 to separate from the first wedge-shaped tooth plate 54 and pull the paddle plate 61 to swing in the opposite direction. When the paddle plate 61 swings in the opposite direction to a position B that is longitudinally symmetrical to position A, it engages with the first wedge-shaped tooth plate 54 that rotates continuously with the mesh tube 53 again, thereby driving the paddle plate 61 to swing back and forth in the circumferential direction in the inner cavity of the mesh tube 53.

[0067] S3, the rubber raw material is screened by the mesh tube 53 and enters the inner cavity of the conveying pipe body 71. The mesh tube 53 drives the driving spiral plate 51 to rotate. The rotating driving spiral plate 51 cooperates with the inner wall of the conveying pipe body 71 to convey the screened rubber raw material to the discharge pipe 73, thereby completing the loading of the rubber raw material.

[0068] In summary, the present invention provides a feeding device and a feeding process for rubber production, wherein the rubber raw material is put into the feed hopper 41, the raw material is guided through the connecting pipe 42, the hose 43 and the guide pipe 47, and enters the inner cavity of the mesh screen tube 53 through the feed port 46, and the motor 31 is started. The motor 31 drives the driving gear 32 to rotate, and the driving gear 32 engages with the driving ring 33 to rotate and drives the driving sleeve 35 to rotate continuously. At this time, the driving block 34 is located in the driving groove 5212, and the driving tube body 5211 is driven to rotate synchronously through the engagement of the driving block 34 with the driving groove 5212, thereby driving the mesh screen tube 53 to rotate and screen the rubber raw material in the mesh screen tube 53. When the driving tube body 5211 rotates, the support rod 45 is located at the limit position. The support rod 45 is in the groove 522, and the driving block 34 is always located in the driving groove 5212 through the supporting effect of the support rod 45 on the limiting groove 522, so that the driving block 34 is always located in the driving groove 5212, ensuring the smooth rotation of the mesh screen tube 53. When the support rod 45 moves into the driving groove 523, the support rod 45 moves along the driving groove 523, and the mesh screen tube 53 loses the support of the support rod 45. The inclined mesh screen tube 53 moves toward the fixed plate 44 under the action of gravity and abuts against the support rod 45 again. At this time, the driving block 34 moves from the driving groove 5212 to the avoiding ring groove 5213, releasing the lock on the driving tube body 5211, and the mesh screen tube 53 stops rotating. When the support rod 45 moves out of the driving groove 523, the support rod 45 pushes the driving block 34 to rotate. The tube body 5211 moves in the direction away from the fixed disk 44, and the driving block 34 moves from the avoidance ring groove 5213 to the driving groove 5212 to drive the driving tube body 5211 to rotate again. At this time, the mesh screen tube 53 continues to rotate, thereby driving the mesh screen tube 53 to perform a periodic motion of alternating rotation and reciprocating movement, thereby promoting the rubber raw material to pass through the mesh screen tube 53 to complete screening. The rotation of the mesh screen tube 53 causes the first wedge-shaped tooth plate 54 to engage with the second wedge-shaped tooth plate 65, and the friction force F causes the paddle plate 61 to pull the spring spring 64 to deform and rotate synchronously with the mesh screen tube 53. When the paddle plate 61 rotates to a position A at a height of one-third of the top of the mesh screen tube 53, the tension generated by the deformed spring spring 64 causes the second wedge-shaped tooth plate 65 to engage with the first wedge-shaped tooth plate 65. A wedge-shaped tooth plate 54 separates and pulls the paddle plate 61 to swing in the direction. When the paddle plate 61 swings in the opposite direction to position B which is longitudinally symmetrical to position A, it engages again with the first wedge-shaped tooth plate 54 which rotates continuously with the mesh screen tube 53, thereby driving the paddle plate 61 to swing back and forth in the circumferential direction in the inner cavity of the mesh screen tube 53, cleaning the inner wall of the mesh screen tube 53 to prevent the sieve holes from being blocked and affecting the screening. At the same time, the raw materials are paddled to improve the screening efficiency. The rubber raw materials are screened through the mesh screen tube 53 and enter the inner cavity of the conveying pipe body 71. The mesh screen tube 53 drives the driving spiral plate 51 to rotate. The rotating driving spiral plate 51 cooperates with the inner wall of the conveying pipe body 71 to convey the screened rubber raw materials to the discharge pipe 73, thereby completing the loading of the rubber raw materials.

The supporting effect of the support rod (45) on the limiting groove (522) makes the driving block (34) always located in the driving groove (5212), thereby ensuring the smooth rotation of the mesh screen tube (53). When the support rod (45) moves into the driving groove (523), the support rod (45) moves along the driving groove (523), and the mesh screen tube (53) loses the support of the support rod (45). The inclined mesh screen tube (53) moves towards the fixed plate (44) under the action of gravity and contacts the support rod (45) again. The driving block (34) moves from the driving groove (5212) to the avoidance ring groove (5213), unlocking the driving tube body (5211), and the mesh screen tube (53) stops rotating.

When the paddle plate (61) rotates to a position A that is one-third of the height of the top of the mesh screen tube (53), the tension generated by the deformed spring spring (64) causes the second wedge-shaped tooth plate (65) to separate from the first wedge-shaped tooth plate (54) and pull the paddle plate (61) to swing in the opposite direction. When the paddle plate (61) swings in the opposite direction to a position B that is longitudinally symmetrical to position A, it engages again with the first wedge-shaped tooth plate (54) that rotates continuously with the mesh screen tube (53), thereby driving the paddle plate (61) to swing back and forth in the circumferential direction in the inner cavity of the mesh screen tube (53).
