Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, specifically to an automatic weighing and batching equipment in synthetic rubber production. Background Technology

[0002] Synthetic rubber, also known as synthetic elastomer, is a highly elastic polymer synthesized artificially. It is one of the three major synthetic materials, and its output is only lower than that of synthetic resin (or plastic) and synthetic fiber. It has various classification methods, a long history of development, and broad research prospects. The closed rubber mixing mill, also known as the internal mixer or kneader, is mainly used for the plasticizing and mixing of rubber. The raw materials need to be proportioned, so an automatic weighing and batching equipment is required.

[0003] Patent CN222807407U discloses an automatic weighing and batching device for rubber production. By setting up a raw material box, a raw material groove, and a feeding port, it avoids the mixing of different raw materials before batching, thus ensuring the purity of the raw materials. By setting up a cleaning groove, a blocking groove, a plug, a blocking rod, a water injection pipe, and a drain pipe, it prevents different raw materials from mixing through the cleaning groove, thus ensuring the purity of the raw materials. However, when the aforementioned device is placed on the weighing body, due to the limitations of manual operation, the placement rack may not be placed in the center of the weighing body surface, which may result in errors in the weighing value. It may also cause the feeding pipe to fail to successfully feed the raw materials into the mixing tank. Utility Model Content

[0004] The purpose of this invention is to provide an automatic weighing and batching equipment for synthetic rubber production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic weighing and batching equipment for synthetic rubber production, comprising a frame, a raw material box inside the frame, feeding ports evenly arranged on the top of the raw material box, feeding pipes evenly arranged on the bottom of the raw material box, and a solenoid valve installed inside the feeding pipes; a weighing body is installed on the inner bottom surface of the frame, a placement rack is placed on the top of the weighing body, and batching barrels are evenly placed on the placement rack, with the batching barrels located directly below the feeding pipes; and a feeding mechanism is provided on the outside of the raw material box.

[0006] Furthermore, the feeding mechanism includes a drive motor, which is fixedly connected to the frame. A first threaded rod is installed at the output end of the drive motor, and the first threaded rod is rotatably connected to the frame. The raw material box is threadedly connected to the first threaded rod. Support arms are symmetrically distributed on both sides of the raw material box. Guide rods are slidably connected to the support arms, and both ends of the guide rods are fixedly connected to the inner wall of the frame.

[0007] Furthermore, a positioning mechanism is provided on the outer side of the placement frame. The positioning mechanism includes a second threaded rod, which adopts a bidirectional thread design and is rotatably connected to the frame. A rocker arm is fixed at the end of the second threaded rod.

[0008] Furthermore, the outer side of the second threaded rod is symmetrically threaded with two moving blocks, and each of the two moving blocks is rotatably connected with a first connecting rod and a second connecting rod. The inner wall of the frame is provided with a guide hole, and the guide hole matches the moving block.

[0009] Furthermore, a connecting rod is rotatably connected to the end of the first connecting rod, a guide groove is provided on the side of the connecting rod, a guide plate is fixed to the inner wall of the frame, and the guide plate matches the guide groove, and two first supports are symmetrically fixed to one side of the inner wall of the frame.

[0010] Furthermore, the first bracket has a first connecting frame slidably connected inside, the surface of the first bracket has a first sliding groove that matches the first connecting frame, the first connecting frame has a first top rod fixed on it, the end of the first top rod is rotatably connected to a first positioning wheel, the connecting rod is rotatably connected to a push-pull rod, and the other end of the push-pull rod is rotatably connected to the first connecting frame.

[0011] Furthermore, a second bracket is fixed to the other side of the inner wall of the frame, and a second connecting frame is slidably connected inside the second bracket.

A second top rod is fixed on the second connecting frame, and a second positioning wheel is rotatably connected to the end of the second top rod. The other end of the second connecting rod is rotatably connected to the second connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The automatic weighing and batching equipment in the production of synthetic rubber drives the first threaded rod to rotate. Since the raw material box is threadedly connected to the first threaded rod, the raw material box is prevented from rotating by the support arm and guide rod and other parts, so that the raw material box slides in the frame. The feeding pipe moves to the top of the batching bucket that needs to be fed, and the raw material is fed into the batching bucket. The weighing body weighs the raw material in the batching bucket, thereby completing the batching work. Furthermore, after the placement rack is placed on the weighing body, by rotating the rocker arm, the first positioning wheel and the second positioning wheel begin to move horizontally and vertically respectively, pushing the placement rack until it moves to the center position above the weighing body, which facilitates accurate weighing of raw materials and ensures that the feeding pipe can smoothly feed the raw materials into the mixing bucket.

[0015] 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.

[0016] Example 1: Please refer to Figure 1 and Figure 2The present invention provides the following technical solution: an automatic weighing and batching equipment for synthetic rubber production, comprising a frame 1, a raw material box 2 inside the frame 1, feeding ports 3 evenly arranged on the top of the raw material box 2, feeding pipes 4 evenly arranged on the bottom of the raw material box 2, and a solenoid valve installed inside the feeding pipes 4; a weighing body 9 is installed on the inner bottom surface of the frame 1, a placement rack 10 is placed on the top of the weighing body 9, and batching barrels 11 are evenly placed on the placement rack 10, with the batching barrels 11 located directly below the feeding pipes 4; a feeding mechanism is provided on the outer side of the raw material box 2; the feeding mechanism includes a drive motor 5, which is fixedly connected to the frame 1, and a first threaded rod 6 is installed at the output end of the drive motor 5, and the first threaded rod 6 is rotatably connected to the frame 1; the raw material box 2 is threadedly connected to the first threaded rod 6; support arms 7 are symmetrically distributed on both sides of the raw material box 2, and guide rods 8 are slidably connected to the support arms 7, with both ends of the guide rods 8 fixedly connected to the inner wall of the frame 1.

[0017] During weighing and batching, the raw materials are placed into the raw material box 2 through the feeding port 3. After the raw material box 2 processes the raw materials, the drive motor 5 is turned on, and the drive motor 5 drives the first threaded rod 6 to rotate. Since the raw material box 2 and the first threaded rod 6 are threadedly connected, and because the support arms 7 are symmetrically distributed on both sides of the raw material box 2, and the guide rods 8 are slidably connected on the support arms 7, and the two ends of the guide rods 8 are fixedly connected to the inner wall of the frame 1, by setting the support arms 7 and the guide rods 8, the rotation of the raw material box 2 can be prevented, so that the raw material box 2 moves horizontally within the frame 1. When the feeding pipe 4 moves to the top of the batching barrel 11, the solenoid valve is opened, and the raw materials fall into the batching barrel 11 under the action of gravity to complete the batching.

[0018] Example 2: Please refer to Figures 2-6Based on Embodiment 1, a positioning mechanism is also disclosed, the specific structure of which is as follows: A positioning mechanism is provided on the outer side of the placement frame 10. The positioning mechanism includes a second threaded rod 12, which adopts a bidirectional thread design and is rotatably connected to the frame 1. A rocker arm 13 is fixed at the end of the second threaded rod 12. Two moving blocks 14 are symmetrically threaded on the outer side of the second threaded rod 12. A first connecting rod 16 and a second connecting rod 26 are rotatably connected to each of the two moving blocks 14. A guide hole 15 is provided on the inner wall of the frame 1, and the guide hole 15 matches the moving block 14. A connecting rod 17 is rotatably connected to the end of the first connecting rod 16. A guide groove 18 is provided on the side of the connecting rod 17. A guide plate 19 is fixed on the inner wall of the frame 1, and the guide plate 19 matches the guide groove 18. Two first supports are symmetrically fixed on one side of the inner wall of the frame 1. A first support 20 is slidably connected to a first connecting frame 21. A first sliding groove 22 is formed on the surface of the first support 20, and the first sliding groove 22 matches the first connecting frame 21. A first push rod 23 is fixed on the first connecting frame 21. A first positioning wheel 24 is rotatably connected to the end of the first push rod 23. A push-pull rod 25 is rotatably connected to the connecting rod 17. The other end of the push-pull rod 25 is rotatably connected to the first connecting frame 21. A second support 27 is fixed on the other side of the inner wall of the frame 1. A second connecting frame 28 is slidably connected to the interior of the second support 27. A second sliding groove 29 is formed on the surface of the second support 27, and the second sliding groove 29 matches the second connecting frame 28. A second push rod 30 is fixed on the second connecting frame 28. A second positioning wheel 31 is rotatably connected to the end of the second push rod 30. The other end of the second connecting rod 26 is rotatably connected to the second connecting frame 28.

[0019] Before adding ingredients, the placement rack 10 needs to be placed on the weighing body 9. Due to the limitations of manual operation, the placement rack 10 may not be positioned at the exact center of the weighing body 9. In this case, the rocker arm 13 needs to be rotated. The rocker arm 13 rotates the second threaded rod 12. The second threaded rod 12 has two symmetrically threaded moving blocks 14, and the second threaded rod 12 adopts a bidirectional thread design. Therefore, the two moving blocks 14 move in opposite directions. When the moving blocks 14 move, the second connecting rod 26 pushes the second top rod 30 through the second connecting frame 28, causing the second positioning wheel 31 at the end of the second top rod 30 to move horizontally and longitudinally, providing water to the placement rack 10. Simultaneously, the second connecting rod 26 pulls the connecting rod 17. With the cooperation of the guide groove 18 and the guide plate 19, the connecting rod 17 moves horizontally and longitudinally. Since the connecting rod 17 is rotatably connected to the push-pull rod 25, and the other end of the push-pull rod 25 is rotatably connected to the first connecting frame 21, the push-pull rod 25 pushes the first top rod 23, so that the first positioning wheel 24 rotatably connected at the end of the first top rod 23 acts on the placement frame 10, providing a horizontal thrust to the placement frame 10, thereby moving the placement frame 10 to the center position of the upper surface of the weighing body 9, avoiding errors during weighing, and preventing the feeding pipe 4 from feeding raw materials outside the mixing bucket 11.

[0020] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
