[0002] The closed rubber mixer is also called a kneading machine, which is mainly used for rubber plasticization and mixing. Among them, the production raw materials need to be proportioned, and cleaning is required to prevent the ingredients from remaining in the batching box. The existing patent (Announcement No.: CN217573617U) discloses an automatic weighing batching device for rubber mixing. The utility model is convenient for cleaning the inside of the placement box by setting a top cover, a water injection pipe and a water outlet pipe to avoid different raw materials from remaining inside the device. However, in actual applications, since there are many kinds of production raw materials, and only one feeding box is set in the above utility model, it is not convenient to add materials to different raw material batching troughs, which is inconvenient to use. For this reason, we propose an automatic weighing batching device for rubber production. Utility Model Content

[0019] Specifically, Figure 1 As shown, when the feeding pipe 17 is docked with one of the batching barrels 4, the other feeding pipes 17 automatically correspond to the remaining batching barrels 4 so as to add the corresponding raw materials therein;

[0020] Further, a screw rod 5 is installed in the frame 2 for transverse movement, and both ends of the screw rod 5 are connected to the frame 2 through bearings. A sliding seat 7 fixed to the bottom of the raw material box 8 is threadedly connected to the screw rod 5. The sliding seat 7 is connected to the bottom of the raw material box 8 through fasteners, and the connection position avoids the feeding pipe 17. A motor 6 connected to the screw rod 5 is installed on the side of the frame 2; starting the motor 6 rotates the screw rod 5, and then the sliding seat 7 moves left and right along the screw rod 5, thereby driving the raw material box 8 to move, so that the feeding pipes 17 connected to different raw material grooves 9 are aligned with different batching barrels 4, so as to add raw materials thereto;

[0021] Furthermore, both sides of the raw material box 8 are connected to the frame 2 by sliding left and right; by means of sliding connection, the raw material box 8 is sufficiently supported and maintains stability;

[0022] Furthermore, a pair of guide rods 18 fixed to both ends of the frame 2 are horizontally arranged above the raw material box 8, support arms 19 are fixed to both sides of the raw material box 8, and a ring sleeve 20 movably sleeved on the guide rod 18 is fixed to the top of the support arm 19; when the raw material box 8 moves along the lead screw 5, the ring sleeve 20 is used to make the support arm 19 drive the upper end of the raw material box 8 to move along the guide rod 18, thereby providing effective upward support to the raw material box 8, thereby improving the moving stability of the raw material box 8;

[0023] Specifically, by setting up a raw material box 8, a raw material groove 9 and a feeding port 10, the raw material groove 9 is used to store different kinds of raw materials, and the feeding port 10 is used to add different kinds of raw materials into the corresponding raw material grooves 9, respectively, so that the staff can add each raw material independently. Compared with the existing technology, the raw materials are added separately to avoid the mixing of different kinds of raw materials before batching, thereby ensuring the purity of the raw materials.

[0024] A water injection pipe 15 and a drainage pipe 23 are connected to one side of the raw material box 8, and a cleaning passage communicating with the water injection pipe 15 and the drainage pipe 23 is provided inside the raw material box 8;

[0025] Further, the cleaning channel includes a cleaning groove 11 connected between adjacent raw material grooves 9, and a pair of raw material grooves 9 near the water injection pipe 15 are respectively connected with connecting grooves 14, and the other ends of the connecting grooves 14 are respectively connected with the water injection pipe 15 and the drainage pipe 23; a joint pipe is embedded in the end of the connecting groove 14, and the water injection pipe 15 and the drainage pipe 23 are sealed on the joint pipe, so that the connecting groove 14 is stably connected with the water injection pipe 15 and the drainage pipe 23;

[0026] Further, a blocking groove 12 connected to the cleaning groove 11 is provided in the raw material box 8, and a blocking rod 13 is inserted in the blocking groove 12; before adding raw materials to the feeding port 10, the blocking rod 13 is first inserted into the blocking groove 12 until the blocking rod 13 is inserted into the cleaning groove 11, and the longitudinal sections of the cleaning groove 11 and the blocking rod 13 are both rectangular, so that the blocking rod 13 blocks the cleaning groove 11 to prevent different raw materials from flowing from the cleaning groove 11 to other raw material grooves 9;

[0027] Further, the upper cover of the feeding port 10 is provided with a sealing plug 21. When it is not necessary to replenish raw materials, the sealing plug 21 is placed on the feeding port 10 to achieve a dustproof effect. An operation port 22 is provided at the top of the frame 2 so that raw materials can be replenished into the raw material box 8 from the top of the frame 2. A plug 16 is inserted at one end of the blocking groove 12 close to the surface of the raw material box 8. When it is necessary to clean the raw material groove 9, the plug 16 is first placed on the end of the blocking groove 12 to seal the blocking groove 12 so that the cleaning liquid can flow in the raw material groove 9, the cleaning groove 11 and the blocking groove 12 for cleaning;

[0028] Specifically, by setting a cleaning groove 11, a blocking groove 12, a plug 16, a blocking rod 13, a water injection pipe 15 and a drain pipe 23, a cleaning liquid is injected into the raw material groove 9 through the water injection pipe 15, so that the cleaning liquid passes through the cleaning groove 11 and flows into other raw material grooves 9, so as to clean all the raw material grooves 9, and the plug is used to close the outer end opening of the blocking groove 12 to prevent the cleaning liquid from flowing out. Compared with the prior art, when adding raw materials into the raw material groove 9, the cleaning groove 11 can be blocked by completely inserting the blocking rod 13 into the blocking groove 12, so as to prevent different kinds of raw materials from mixing with each other through the cleaning groove 11, thereby ensuring the purity of the raw materials and improving practicality.

[0029] Working principle:

[0030] Since rubber production raw materials mainly include three kinds, at least three raw material grooves 9 and feeding pipes 17 are provided, and they are arranged side by side, or two rows are provided. If two rows of raw material grooves 9 and feeding pipes 17 are provided, the raw materials in each row of raw material grooves 9 are the same. Figure 1 As shown, each feeding tube 17 corresponds to a batching barrel 4, and each batching barrel 4 of each batch requires raw materials in the same ratio, and the raw materials in each row of the raw material groove 9 are named raw material 1, raw material 2 and raw material 3. By moving the raw material box 8 left and right, different feeding tubes 17 correspond to different batching barrels 4, so as to add corresponding raw materials to different batching barrels 4. For example, if a batch of batching barrels 4 requires raw materials 1 and raw material 3 in a certain ratio, then move the raw material box 8 left and right, first add raw material 1 to the batching barrel 4 one by one, and after adding each batching barrel 4, weigh the current total weight and compare it with the last weighing value to ensure that the weight of the raw materials added to a single batching barrel 4 meets the requirements, and then add raw material 3, and the remaining steps are the same as the steps of adding raw material 1.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
