Description
Technical Field
[0001] This utility model relates to the field of PVC production, and in particular to a new type of automatic mixing and batching machine for PVC auxiliary materials. Background Technology
[0002] In the production of PVC (polyvinyl chloride), ingredient formulation is a crucial step. PVC production requires not only the main material, polyvinyl chloride resin, but also the addition of various auxiliary materials, such as stabilizers, plasticizers, fillers, pigments, and additives. The precise proportions of these auxiliary materials have a significant impact on the quality, performance, and production efficiency of the final product.
[0003] In the past, many PVC production companies relied on manual addition of auxiliary materials. Operators typically used simple measuring tools (such as cups or spoons) and experience to add materials. However, manual labor is highly subjective, and different operators may have different readings of the measuring tools. Furthermore, it is difficult to ensure that the amount of auxiliary material measured each time is completely consistent during repeated batching. This error affects the production quality of PVC products.
[0004] Therefore, a novel automatic mixing and batching machine for PVC auxiliary materials is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a new type of automatic mixing and batching machine for PVC auxiliary materials, which aims to improve the problems of large errors in manual batching and difficulty in accurately controlling the amount of auxiliary materials added, thus affecting the quality of PVC products.

[0030] 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.
[0031] Reference Figure 1This utility model provides an embodiment of an automatic mixing and batching machine for PVC auxiliary materials, including a mixing tank 1. The mixing tank 1 is a type of mixing equipment, with a built-in motor and mixing blades for mixing. A feeding pipe is provided at the top, through which water for mixing can be added. A discharge pipe is provided at the bottom, through which the mixed raw materials can be discharged. The mixing tank 1 is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. A support plate 2 is fixedly connected to the right surface of the mixing tank 1. A feeding component for adding auxiliary materials is provided on the upper surface of the support plate 2. Since the amount of auxiliary materials used is small, the accuracy of the ratio is high, so a feeding component is needed to accurately control the amount of materials added.
[0032] Reference Figure 1 - Figure 2 The feeding assembly includes a feeding tank 31, which is sealed inside. The front surface of the feeding tank 31 is marked with graduations. The feeding tank 31 is transparent. A discharge bin 32 is fixedly connected to the right surface of the feeding tank 31. A sealing gasket 33 is piston-connected to the inner wall of the feeding tank 31. The inner layer of the sealing gasket 33 is made of a hard, non-deformable material, while the surface is made of rubber to maintain a seal. A connecting rod 34 is fixedly connected to the upper surface of the sealing gasket 33, and a pressure plate 35 is fixedly connected to the upper surface of the connecting rod 34. The pressure plate 35, connecting rod 34, and sealing gasket 33 move synchronously. A discharge pipe 36 is penetrating and fixedly connected to the left surface of the feeding tank 31. The auxiliary material inside the feeding tank 31 can only be discharged from the discharge pipe 36 and can only be discharged into the mixing tank 1. Multiple feeding assemblies are provided, evenly distributed on the support. On plate 2, different types of auxiliary materials are added. A one-way valve 37 is installed in the middle section of the discharge pipe 36. A feed pipe 38 is fixedly connected through the right surface of the feeding tank 31. The auxiliary materials can only enter the feeding tank 31 from the feed pipe 38. The auxiliary materials are normally fluids such as plasticizers, stabilizers, fillers, and colorants, which can flow along the pipe. A one-way valve 39 is installed in the middle section of the feed pipe 38. Both one-way valve 37 and one-way valve 39 are existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. One-way valve 37 and one-way valve 39 can make the fluid flow only in one direction. A metering component is installed on the upper surface of the feeding tank 31. The metering component can accurately control the amount of auxiliary materials added at one time.
[0033] Reference Figure 1 - Figure 2The lower surface of the feeding tank 31 is fixedly connected to the upper surface of the support plate 2. The upper surface of the discharge bin 32 is set as an opening to facilitate the addition of auxiliary materials. The connecting rod 34 passes through and is slidably connected to the upper surface of the feeding tank 31, and slides longitudinally. The discharge pipe 36 passes through and is fixedly connected to the right surface of the mixing tank 1. The discharge pipe 36 connects the mixing tank 1 and the feeding tank 31. The feed pipe 38 passes through and is fixedly connected to the left surface of the discharge bin 32. The feed pipe 38 connects the feeding tank 31 and the discharge bin 32. The auxiliary materials entering the feed pipe 38 come from the discharge bin 32.
[0034] Reference Figure 1 , Figure 3 , Figure 4 The metering component includes a U-shaped frame 41. The U-shaped frame 41 has an opening slot, and a groove 401 and a slot 402 are provided on the inner wall of the front side of the U-shaped frame 41. One end of a connecting spring 42 is fixedly connected to the inner wall of the top of the U-shaped frame 41. The other end of the connecting spring 42 is fixedly connected to the upper surface of the pressure plate 35. When the pressure plate 35 moves downward, it will stretch the connecting spring 42 to generate a reaction force. In the absence of external force, the connecting spring 42 will pull the pressure plate 35 to the top of the inner wall of the groove 401. A stop block 43 is slidably connected to the inner wall of the groove 401. The stop block 43 moves longitudinally. A pull ring 44 is elastically connected to the inner wall of the stop block 43 through a compression spring 46. A rod 45 is fixedly connected to the front surface of the pull ring 44. The pull ring 44 and the rod 45 move synchronously.
[0035] Reference Figure 1 , Figure 3 , Figure 4 The lower surface of the U-shaped frame 41 is fixedly connected to the upper surface of the feeding tank 31. The pressure plate 35 is slidably connected to the inner wall of the slide 401 and moves longitudinally. Multiple sets of slots 402 are provided, and the multiple sets of slots 402 are evenly distributed longitudinally along the trajectory of the slide 401. The slide 401 and the slots 402 are connected. One end of the compression spring 46 is fixedly connected to the front surface of the pull ring 44, and the other end of the compression spring 46 is fixedly connected to the rear surface of the stop block 43. When the pull ring 44 moves backward, it will stretch the compression spring 46 to generate a reaction force. The insertion rod 45 passes through and is slidably connected to the rear surface of the stop block 43. The insertion rod 45 is inserted into the inner wall of the slot 402. When the insertion rod 45 and the slot 402 are inserted, the stop block 43 will be limited. The stop block 43 will limit the maximum height that the pressure plate 35 can rise. When the upper surface of the pressure plate 35 contacts the stop block 43, it will not be able to move.
[0036] Working principle: First, add the required auxiliary materials into the feeding hopper 32. Then, adjust the initial position of the sealing gasket 33 according to the requirements to change the amount added at one time. During adjustment, first move the pull ring 44 backward to drive the insertion rod 45 backward and disengage it from the slot 402 to release the limit. The backward-moving pull ring 44 will stretch the compression spring 46 to generate a reaction force. After the limit is released, move the stop block 43 upward. When it is almost at the appropriate position, release the pull ring 44. At this time, the compression spring 46 is in a stretched state. When it moves to the appropriate position, the insertion rod 45 will be aligned with the slot 402. The compression spring 46 will pull the insertion rod 45 forward to align it with the slot 402.
[0037] At this time, since the upper surface of the pressure plate 35 is not in contact with the stop block 43, the connecting spring 42 will pull the pressure plate 35 upward until it contacts the stop block 43. During this process, the pressure plate 35 will drive the connecting rod 34 and the sealing gasket 33 to move upward. When the sealing gasket 33 moves upward, the feeding tank 31 will be under negative pressure. Therefore, the auxiliary material in the discharge bin 32 will enter the feeding tank 31 through the feed pipe 38 and the one-way valve 39, filling the area below the sealing gasket 33.
[0038] When it is necessary to add auxiliary materials, the pressure plate 35 is pressed down to drive the connecting rod 34 and the sealing gasket 33 to move downward. The downward moving sealing gasket 33 will press the auxiliary materials inside the feeding tank 31 and enter the mixing tank 1 from the discharge pipe 36 through the one-way valve 37 to realize the addition.
[0039] When the pressure plate 35 moves downward, it stretches the connecting spring 42 to generate a reaction force. After the external force is released, the connecting spring 42 will pull the pressure plate 35, the connecting rod 34 and the sealing gasket 33 upward. When the sealing gasket 33 moves upward, it will suck in the same amount of auxiliary material from the discharge bin 32 again.
[0040] When adjusting the initial position of the sealing gasket 33, the amount of auxiliary material added at one time can be determined by observing the scale on the feeding tank 31.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
