Description

Technical Field

[0001] This utility model relates to the technical field of plasticizer raw material addition devices, and more specifically, to a raw material addition device for plasticizer production. Background Technology

[0002] Plasticizers are chemical additives used to improve the processing performance and physical properties of polymers. Their core function is to enhance the flexibility, ductility and processing performance of materials by weakening the intermolecular forces of polymers and increasing the mobility of molecular chains.

[0003] Currently, in the plasticizer production process, a raw material adding device is required to add raw materials into the production equipment. However, the commonly used original adding device cannot quickly adjust the amount of material added each time according to actual needs. For example, a raw material adding device for plasticizer production disclosed in publication number CN218166906 U includes a cylinder and a column. The bottom end of the cylinder is fixedly connected to an installation plate through a feeding trough. A sealing frame is glued to the bottom end of the installation plate. A feeding hopper is fixedly provided at the top of the cylinder. A column is provided inside the cylinder. A metering groove is opened at the top of the column. Two sealing strips are engaged and connected to the surface of the column.

[0004] As can be seen from the above-disclosed scheme, the raw material adding device limits the amount of raw material added by means of a metering groove set on the cylindrical surface. However, the volume of the metering groove is fixed. When it is necessary to change the amount of raw material added, the raw material adding device cannot be used, which causes inconvenience to the user and narrows the scope of application.

A handle 12 is fixedly connected to the surface of the cover plate 11, allowing the user to manually open and close the cover plate 11. A feeding assembly is fixedly connected to the surface of the housing 1. A rotating mechanism 3 is installed inside the housing 1. The rotating mechanism 3 includes a stepper motor 31 with a control switch mounted on the top of the housing 1 for easy operation. One end of the stepper motor 31 is bolted to the surface of the housing 1. A rotating shaft 32 is fixedly connected to the output end of the stepper motor 31. A rotating frame 33 is fixedly mounted on the surface of the rotating shaft 32. The outer side of the rotating frame 33 is fixedly connected to... A turntable 34 has a guide groove 35 on its surface and several metering holes 36 at the bottom of the guide groove 35. A stepper motor 31 can drive the turntable 34 to rotate, so that the metering holes 36 are connected to the feeding pipe 14 to complete the feeding. Then, it rotates to the discharge hole 23 to add raw materials in a metered manner. The bottom of the raw material adding device housing 1 is fixedly connected to the discharge hopper 2. One end of the discharge hopper 2 is provided with a discharge trough 21. The bottom of the discharge trough 21 is connected to the plasticizer production equipment to facilitate the addition of raw materials into the plasticizer production equipment for production. The top of the discharge trough 21 is fixedly connected to the baffle 22. The surface of the baffle 22 has a discharge hole 23. The inner diameter of the discharge hole 23 is larger than the maximum inner diameter of the metering hole 36. The bottom of the discharge hopper 2 is provided with a mounting flange 24, which is fixed to the plasticizer production equipment by bolts.

[0027] The feeding assembly includes a feeding hopper 13, with a feeding pipe 14 fixedly connected to the bottom of the feeding hopper 13. The surface of the feeding pipe 14 is fixedly connected to the surface of the raw material adding device housing 1. One end of the feeding pipe 14 is fixedly connected to a limiting ring 15, which can limit the upward movement of the scraper sleeve 16. The bottom of the limiting ring 15 is fixedly connected to the scraper sleeve 16, which is located in the guide groove 35. Its bottom contacts and presses against the bottom of the guide groove 35, which can prevent the internal raw material from leaking to the outside of the metering hole 36. An adsorption plate is fixedly embedded in the bottom of the cover plate 11. The adsorption plate is made of a strong magnet and is arc-shaped. The surface of the adsorption plate is movably connected to the open end face of the raw material adding device housing 1. An iron sheet is provided at the open end, which automatically fixes the closed position of the cover plate 11 by magnetic adsorption.

[0028] A sealing plug 37 is movably connected to one end of the metering orifice 36. The sealing plug 37 is made of elastic wear-resistant rubber. The end face of the sealing plug 37 is on the same plane as the bottom of the guide groove 35. The sealing plug 37 can be pried out with a flathead screwdriver. The sealing plug 37 can seal the unused metering orifice 36. A bearing seat 25 is fixedly installed at the center of the baffle 22. One end of the bearing seat 25 is fixedly connected to one end of the rotating shaft 32 to ensure the stability of the rotation position of one end of the rotating shaft 32. An anti-wear pad 38 is fixedly connected to the bottom of the turntable 34. The surface of the anti-wear pad 38 has a through hole 39. The through hole 39 is coaxial with the metering orifice 36 to facilitate downward material leakage. The anti-wear pad 38 can prevent the bottom of the turntable 34 from wearing against the surface of the baffle 22.

[0029] In use, the raw material adding device for plasticizer production is first fixed to the plasticizer production equipment with bolts, so that the feeding trough 21 is connected to the feed inlet of the plasticizer production equipment. Then, the plasticizer production raw material is added into the feeding hopper 13. Next, the stepper motor 31 is turned on, and the operation of the stepper motor 31 causes the rotating shaft 32 to drive the turntable 34 to rotate. The rotation of the turntable 34 causes the scraper sleeve 16 to slide along the guide groove 35. At the same time, the rotation of the turntable 34 connects the upper end of the opened metering orifice 36 with the lower end of the scraper sleeve 16, thereby allowing the raw material in the feeding tube 14 to be added downwards. The material is added into the metering orifice 36, and then the metering orifice 36, filled with raw material, continues to rotate with the turntable 34. At the same time, the bottom is sealed by the baffle 22. When the metering orifice 36 rotates to the position of the discharge orifice 23, the raw material in the metering orifice 36 is added downward through the discharge orifice 23 into the discharge trough 21, and then metered into the plasticizer production equipment through the discharge trough 21. If the amount of raw material added needs to be changed, the cover plate 11 is manually opened so that the operator can see the top of the turntable 34. Then the opened metering orifice 36 is sealed with the sealing plug 37, and then the metering orifice 36 of the required capacity is opened.
