Description

Technical Field

[0001] This utility model relates to the field of PVC tarpaulin production technology, specifically to a slurry feeding device for PVC tarpaulin production. Background Technology

[0002] The slurry used in the production of PVC tarpaulins is mainly PVC paste resin. This slurry is produced by coating PVC paste resin on both sides of a polyester base fabric and then molding it in one step using a dip-coating process. This ensures that the gaps in the fabric are filled with PVC slurry, thus providing excellent waterproof performance. During the production of PVC tarpaulins, the PVC paste resin slurry needs to be fed in. A search revealed that patent CN213966430U discloses a slurry feeding device for lithium battery production. Its feeding structure includes a first feeding pipe and a second feeding pipe connected together. A first spiral stirring rod is installed inside the first feeding pipe, and a second spiral stirring rod is installed inside the second feeding pipe. The first and second spiral stirring rods are connected by a gear set, thereby enabling effective and stable mixing of the slurry. The first feeding pipe has a second discharge pipe connected to its lower end, which is connected to a recycling tank. When feeding is completed or when feeding needs to be stopped for a long time, the drive motor reverses, causing the first and second spiral stirring rods to rotate in the opposite direction, sending the slurry remaining on the first and second feeding pipes into the recycling tank. However, the discharge port at the top is fixed in height. If the inlet of the equipment to be fed is low, it still needs to be raised to the fixed discharge port for feeding, resulting in high energy consumption. Therefore, a slurry feeding device for PVC tarpaulin production is designed to facilitate discharge at different heights, meet the feeding requirements of different heights, and reduce energy waste during feeding.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slurry feeding device for PVC tarpaulin production, comprising a base frame, a feeding pipe, and a hopper. The feeding pipe and the hopper are fixedly installed on the base frame, and the bottom of the feeding pipe is connected to the bottom of the hopper. Multiple side discharge ports distributed vertically are provided on the side wall of the feeding pipe. Each side discharge port is provided with a sealing sleeve that is slidably fitted with the feeding pipe. One side of the sealing sleeve is fixedly connected to a feeding pipe port that is adapted to the side discharge port. The length of the other side of the sealing sleeve away from the feeding pipe port is longer than the length of the side discharge port. Each side discharge port is provided with an adjustment mechanism for driving the sealing sleeve to slide and lift. The bottom of the base frame also includes a lifting mechanism. A conveying screw is rotatably connected inside the feeding pipe, and a feeding motor for driving the conveying screw to rotate is fixedly installed at the bottom of the feeding pipe.

[0007] Preferably, the adjusting mechanism includes a fixed block fixedly mounted on the feeding pipe, an adjusting screw rotatably connected to the fixed block via an adjusting motor, a slider threadedly connected to the adjusting screw and fixedly connected to the sealing sleeve, and a limit block fixedly mounted on the end of the adjusting screw away from the adjusting motor.

[0008] Preferably, the lifting mechanism includes two vertical screws rotatably connected to the bottom of the base frame. A lifting bar is threaded onto the vertical screw. Support legs are fixedly installed at both ends of the lifting bar. Each support leg is guided and slidably fitted with a vertical guide rod fixedly connected to the base frame.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a slurry feeding device for PVC tarpaulin production, which has the following beneficial effects:

[0014] This PVC tarpaulin production slurry feeding device, through the cooperation of a feeding pipe, hopper, conveying screw, and feeding motor, facilitates the lifting of materials and feeding them through the top of the feeding pipe. Multiple side discharge ports, arranged vertically, are opened on the side wall of the feeding pipe. These side discharge ports are sealed by a sealing sleeve on the side furthest from the feeding pipe opening. When different feeding heights are required, the sealing sleeve at any height can be adjusted via an adjustment mechanism to move the sealing sleeve and the feeding pipe opening as a whole, thereby connecting the feeding pipe opening with the side discharge port at that location, allowing for feeding at that point. A lifting mechanism can also raise the hopper and feeding pipe as a whole, further reducing feeding energy consumption. This PVC tarpaulin production slurry feeding device facilitates feeding at different heights, meeting various feeding requirements and reducing energy waste during feeding.
