Description

Technical Field

[0001] The invention relates to the technical field of internal mixers, in particular to an internal mixer with a front and rear double-sided dump bucket for material discharge. Background Art

[0002] An internal mixer is a device used for mixing polymer materials such as rubber and plastic. It is mainly used to mix various raw materials (such as rubber, plastic, fillers, additives, etc.) under high temperature, high pressure and strong shear force to achieve ideal processing performance and physical properties. The high-speed rotation of the rotor exerts strong shear, extrusion and friction on the material. At the same time, combined with an external heating or cooling system, the material is quickly mixed and evenly mixed in a closed mixing chamber.

[0003] After the raw materials are mixed, they are discharged through a discharging device. The discharge method can be to pour them out by flipping the bucket. If the mixed raw materials are rubber or plastic, some of the fine raw materials will adhere to the inner wall of the bucket during the pouring process, and cannot be poured out, resulting in material loss and waste. Secondly, if the type of raw materials mixed next time is different, the residual raw materials may be mixed into subsequent batches, resulting in impure product ingredients and affecting sales.

[0024] The following combines Figures 1 - 9 to describe a front and rear double-sided tipping and discharging structure of a mixer.

[0025] As Figures 1 - 5 shown, in one embodiment, a front and rear double-sided tipping and discharging structure of a mixer includes a machine body 1 and a worm 2 rotatably installed on the machine body 1, and further includes: a worm gear 3, rotatably installed on the machine body 1 and in transmission connection with the worm 2; a rotating shaft 4, fixedly installed on one side of the worm gear 3; a tipping bucket 5, fixedly installed at one end of the rotating shaft 4 away from the worm gear 3, and the other end is rotatably connected to the machine body 1; rotors 6, rotatably arranged at the bottom of the inner wall of the tipping bucket 5, and the number is set to two; a horizontal plate 7, fixedly installed at the bottom of the tipping bucket 5; lead screws 10, rotatably installed on the horizontal plate 7, the number is set to multiple, and they are arranged in a circular array on the outside of the tipping bucket 5; a moving frame 9, movably installed on the outside of the lead screws 10, and one end is slidably connected to the outer wall of the tipping bucket 5; a knocking assembly 8, arranged on the moving frame 9 and used for knocking the outer wall of the tipping bucket 5.

[0026] Specifically, pour various raw materials to be processed into the tipping bucket 5. The forward and reverse rotation of the two rotors 6 can evenly mix the materials in the tipping bucket 5. Barbs or spiral blades can be arranged on the outer side of the rotor 6 to crush and mix the raw materials. After the material mixing and kneading are completed, start the motor of the worm 2 arranged on the machine body 1 to drive the worm 2 to rotate. The rotation of the worm 2 drives the worm gear 3 and the rotating shaft 4 to rotate. The rotating shaft 4 is installed on one side of the bottom of the tipping bucket 5. The rotation of the rotating shaft 4 will drive the tipping bucket 5 to turn over and pour out the raw materials in the tipping bucket 5. After a period of time when the turning over is completed, most of the materials in the tipping bucket 5 are all poured out, but there is still a part of the raw materials adhering to the inner wall of the tipping bucket 5. Start the motor of the plurality of lead screws 10. The rotation of the lead screws 10 drives the moving frame 9 to move from the bottom to the top along the bottom of the tipping bucket 5. During the movement of the moving frame 9, the outer wall of the tipping bucket 5 is knocked by the knocking component 8 to make the tipping bucket 5 vibrate, so that the raw materials adhering to the inner wall of the tipping bucket 5 are no longer adhered to the tipping bucket 5, which is convenient for the operator to sweep them out. The cross plate 7 provides a supporting function for the lead screws 10. When the worm 2 rotates in the reverse direction, it will drive the tipping bucket 5 to turn back to the vertical state. Continuing to rotate the worm 2 in the reverse direction will drive the tipping bucket 5 to turn over in the reverse direction by a certain angle and then stop. At this time, the tipping bucket 5 can be cleaned. After the cleaning is completed, materials can be poured in for a new round of mixing and kneading.

[0027] Refer to Figure 3 and Figure 5 As shown, in this embodiment, the knocking component 8 includes a knocking rod 81. The knocking rod 81 is horizontally movably connected to the moving frame 9. One end of the knocking rod 81 is movably abutted against the outer wall of the tipping bucket 5. A positioning ring 82 is fixedly arranged on the moving frame 9, and the knocking rod 81 movably penetrates through the positioning ring 82.

[0028] Specifically, during the process of the moving frame 9 moving from the bottom to the top of the tipping bucket 5 along the lead screw 10, the knocking rod 81 reciprocates horizontally along the moving frame 9. One end of the knocking rod 81 will repeatedly impact the outer wall of the tipping bucket 5 to make the tipping bucket 5 vibrate, shaking off the raw materials adhering to the inner wall. The end of the knocking rod 81 in contact with the outer wall of the tipping bucket 5 can use a leather hammer, so as not to damage the outer wall of the tipping bucket 5. During the reciprocating movement of the knocking rod 81, it will pass through the positioning ring 82, which can improve the stability of the knocking rod 81 during the movement.

[0029] Refer to Figure 5 As shown, in this embodiment, a plurality of tooth-shaped grooves 83 are horizontally linearly arranged at the top of the knocking rod 81. A round rod 84 is fixedly arranged on one side of the moving frame 9. A swinging rod 85 is movably sleeved on the outer side of the round rod 84. A driving gear 86 is arranged at the bottom of the swinging rod 85, and the driving gear 86 is meshed with the tooth-shaped grooves 83 for transmission.

[0030] Specifically, during the process of the moving frame 9 moving from the bottom to the top of the tipping bucket 5, the swing rod 85 swings reciprocally. The swing rod 85 rotates relative to the round rod 84. During the reciprocal swing of the swing rod 85, the driving gear 86 at the bottom will engage with the tooth wire groove 83, thereby driving the knocking rod 81 to move horizontally back and forth. During the reciprocal movement of the knocking rod 81, it will impact the outer wall of the tipping bucket 5, generating a vibration sensation to shake off the adhering raw materials.

[0031] Refer to Figure 5 As shown, in this embodiment, a cross bar 11 is movably arranged above the round rod 84 and penetrates through the moving frame 9. One end of the cross bar 11 is fixedly connected to a disc 12, and a positioning rod 13 is fixedly arranged on the disc 12. A notch 851 is formed on the swing rod 85, and the end of the positioning rod 13 away from the disc 12 is movably connected to the notch 851.

[0032] Specifically, during the process of the moving frame 9 moving from the bottom to the top of the tipping bucket 5, the cross bar 11 is rotated. The rotation of the cross bar 11 will drive the disc 12 to rotate, thereby driving the positioning rod 13 to rotate. During the rotation of the positioning rod 13, it will reciprocally move relative to the notch 851, and further, the reciprocal swing of the swing rod 85 can be realized. Through the cooperation of the driving gear 86 and the tooth wire groove 83, the reciprocal movement of the knocking rod 81 can be realized, and it can impact the outer wall of the tipping bucket 5.

[0033] Refer to Figures 3 - 5 As shown, in this embodiment, the end of the cross bar 11 away from the disc 12 movably penetrates through the moving frame 9 and a positioning gear 14 is fixedly arranged at the end. A rack 15 is fixedly arranged on the outer wall of the tipping bucket 5, and the positioning gear 14 is in meshing transmission with the rack 15.

[0034] Specifically, during the upward movement of the moving frame 9, the positioning gear 14 will engage with the rack 15, thereby realizing the rotation of the positioning gear 14 and the cross bar 11. The rotation of the cross bar 11 will drive the disc 12 and the positioning rod 13 to rotate. Through the positional relationship between the positioning rod 13 and the notch 851, the swing rod 85 can swing left and right during the upward movement, and further, the horizontal reciprocal movement of the knocking rod 81 can be realized.

[0035] Refer to Figure 3 and Figures 6 - 7 As shown, in this embodiment, a plurality of positioning plates 16 are fixedly arranged at the top of the tipping bucket 5. A rotating rod 17 is rotatably arranged on the positioning plate 16. A lifting plate 18 is threadedly and adaptively connected to the outside of the rotating rod 17. A moving groove 181 is formed on one side of the lifting plate 18. A scraping plate 19 is movably arranged in the moving groove 181. One side of the scraping plate 19 is movably abutted against the inner wall of the tipping bucket 5. A fixing rod 20 is fixedly arranged on one side of the positioning plate 16, and the fixing rod 20 movably penetrates through the lifting plate 18.

[0036] Specifically, during the movement of the moving frame 9 from the bottom to the top of the tipping bucket 5, the rotating rod 17 is rotated. Since the rotating rod 17 is threadedly and adaptively connected to the lifting plate 18, the rotation of the rotating rod 17 will drive the lifting plate 18 to move upward along the fixed rod 20. The fixed rod 20 can prevent the lifting plate 18 from deflecting during the upward movement. During the upward movement of the lifting plate 18, a part of the scraping plate 19 is located in the moving groove 181, and the other end is in contact with the inner wall of the tipping bucket 5. In this way, a part of the raw materials adhering to the inner wall of the tipping bucket 5 can be scraped to the outlet of the tipping bucket 5, which is convenient for the operator to collect the adhering raw materials.

[0037] Refer to Figures 6 - 9 As shown, in this embodiment, a groove 182 is formed on one side of the lifting plate 18 where the moving groove 181 is located. A movable rod 21 is movably arranged in the groove 182. One end of the movable rod 21 movably penetrates the inner wall of the groove 182 and is located in the moving groove 181, and the end is fixedly connected to one side of the scraping plate 19. The other end movably penetrates the lifting plate 18. A movable block 22 is fixedly sleeved on the outer side of the movable rod 21. One end of the movable block 22 is connected to the inner wall of the groove 182 through a positioning spring 23.

[0038] Specifically, during the upward movement of the lifting plate 18 along the inner wall of the tipping bucket 5, the movable rod 21 is pushed towards the inner wall of the tipping bucket 5. The movable rod 21 passes through the groove 182 and the moving groove 181 to push the scraping plate 19 to move outwards from the moving groove 181, so that one end of the scraping plate 19 is in contact with the inner wall of the tipping bucket 5. In this way, the adhering raw materials can be scraped to the outlet position of the tipping bucket 5 during the movement. During this process, the movable block 22 will also move along with it. During the movement, the positioning spring 23 will be compressed, and this state is maintained to move the scraping plate 19 to the top of the tipping bucket 5.

[0039] Refer to Figures 6 - 9 As shown, in this embodiment, an elastic clamping member 24 is arranged in the groove 182. A clamping groove 221 is formed at the bottom of the movable block 22. The clamping groove 221 is movably clamped with the elastic clamping. A reset rod 25 is movably arranged in the groove 182. One end of the reset rod 25 movably penetrates the inner wall of the groove 182 and the end is located in the moving groove 181. The other end movably penetrates one side of the lifting plate 18. A reset block 26 is fixedly sleeved on the outer side of the reset rod 25. A top plate 27 is arranged at the bottom of the reset block 26. The positioning plate 16 is movably abutted against the elastic component. The reset block 26 is connected to the inner wall of the groove 182 through a reset spring 28.

[0040] Specifically, when the lifting plate 18 moves upward along the inner wall of the tipping bucket 5, at this time, the elastic clamping member 24 in the groove 182 is in a normal extended state, and the clamping groove 221 formed at the bottom of the movable block 22 is clamped with the elastic clamping member 24. At this time, the positioning spring 23 is in a compressed state, and the return spring 28 is in a normal telescopic state. One end of the scraping plate 19 abuts against the inner wall of the tipping bucket 5. When the lifting plate 18 and the scraping plate 19 are about to move to the top of the tipping bucket 5, the return rod 25 is moved horizontally. The movement of the return rod 25 will drive the return block 26 and the top plate 27 to move together. After the top plate 27 moves a certain distance, it will abut against the tilted elastic clamping member 24 and drive the elastic clamping member 24 to be compressed downward. During this process, the return spring 28 will be compressed, and the clamping groove 221 will be disengaged from the elastic clamping member 24. Under the action of the positioning spring 23, the movable block 22 and the movable rod 21 will be driven to move away from the inner wall of the tipping bucket 5. The movement of the movable rod 21 will drive the scraping plate 19 to move into the movement groove 181. Moreover, this movement is instantaneous and relatively fast, so that the raw materials attached to the surface of the scraping plate 19 can fall off. Secondly, during the process of the lifting plate 18 and the scraping plate 19 moving back to the bottom of the tipping bucket 5, the scraping plate 19 will not abut against the inner wall of the tipping bucket 5, so as to avoid scraping the raw materials near the opening of the tipping bucket 5 back to the bottom of the tipping bucket 5, which is not convenient for the operator to collect.

[0041] Refer to Figures 6 - 9 As shown, in this embodiment, a connecting rod 29 is fixedly arranged on the inner wall of the tipping bucket 5. One end of the connecting rod 29 is fixedly provided with a vertical plate 30. An inclined groove 301 is formed at the bottom of the vertical plate 30. One end of the movable rod 21 is movably abutted against the inclined groove 301. A return plate 31 is fixedly arranged on one side of the vertical plate 30. A notch 311 is formed at the top of the return plate 31. One end of the return rod 25 is movably abutted against the notch 311.

[0042] Specifically, when the lifting plate 18 is at the bottom of the tipping bucket 5, one end of the movable rod 21 abuts against the higher position of the inclined groove 301. The movable rod 21 drives the scraping plate 19 to abut against the inner wall of the tipping bucket 5. The clamping groove 221 is clamped with the elastic clamping member 24, and the movable rod 21 remains in a fixed state. At this time, when the lifting plate 18 is moved upward, the scraping plate 19 will move upward while keeping in contact with the inner wall of the tipping bucket 5. At the same time, one end of the reset rod 25 moves along the lower position of the notch 311 opened on the reset plate 31, and the reset spring 28 is in a normal telescopic state. When the lifting plate 18 is about to move to the opening of the tipping bucket 5, the reset rod 25 will move from the lower position to the higher position along the notch 311, and the reset rod 25 will move horizontally towards the inner wall of the tipping bucket 5. The movement of the reset rod 25 drives the reset block 26 and the top plate 27 to move. During this process, the reset spring 28 will be compressed. During the movement of the top plate 27, it abuts against the elastic clamping member 24 and thus moves the elastic clamping member 24 downward, so that the elastic clamping member 24 is no longer clamped with the clamping groove 221. Under the action of the positioning spring 23, it drives the movable rod 21 and the scraping plate 19 to move quickly in the reverse direction. One end of the movable rod 21 abuts against the lower position of the inclined groove 301. Subsequently, the lifting plate 18 and the scraping plate 19 will move downward, the scraping plate 19 will not abut against the inner wall of the tipping bucket 5, and the reset rod 25 will also move from the higher position to the lower position along the notch 311 until it reaches the lower position. During this process, under the action of the reset spring 28, it drives the reset rod 25, the reset block 26 and the top plate 27 to move in the reverse direction to the initial position. Due to the loss of the abutting force of the top plate 27, the elastic clamping member 24 will tilt upward to return to the initial state. When the lifting plate 18 is about to descend to the bottom of the tipping bucket 5, the movable rod 21 moves from the lower position to the higher position along the inclined groove 301. The movable rod 21 will move horizontally, driving the movable block 22 to move horizontally. During the movement of the movable block 22, it abuts against the elastic clamping member 24 and presses the elastic clamping member 24 downward. When the movable block 22 moves horizontally until the clamping groove 221 moves to the other side of the elastic clamping member 24, the elastic clamping member 24 loses the downward pressing force of the movable block 22 and will tilt upward to be clamped with the clamping groove 221. At this time, the movable rod 21 can remain stationary, and the scraping plate 19 abuts against the inner wall of the tipping bucket 5. Just keep moving upward in this state. The connecting rod 29 provides a supporting role for the vertical plate 30 and the reset plate 31.

[0043] Refer to Figure 4 As shown, in this embodiment, the top of the lead screw 10 and the top of the rotating rod 17 are connected by a belt 32 for transmission.

[0044] Specifically, the rotation of the lead screw 10 drives the rotating rod 17 to rotate synchronously through the belt 32. While the knocking rod 81 knocks on the outer wall of the tipping bucket 5, the scraping plate 19 can also abut against the inner wall of the tipping bucket 5, which can further prevent the raw materials from adhering to the inner wall of the tipping bucket 5.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0046] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
