Description

Technical Field

[0001] This application relates to the field of pigment paste conveying technology, specifically to a pigment paste conveying device. Background Technology

[0002] Pigment paste conveying devices are mechanical equipment specifically designed for conveying pigment pastes. They are widely used in various industrial fields such as coatings, inks, plastics, textiles, printing, and papermaking. Their core function is to accurately and stably convey high-viscosity pigment pastes containing solid particles or prone to sedimentation from storage containers (such as paste barrels or tanks) to production equipment (such as sprayers, printing presses, and mixing tanks) to meet the continuous and uniform feeding requirements of pigment pastes in automated production processes.

[0003] Currently, pigment paste conveying devices generally use pumps such as piston pumps for extraction and conveying. However, when the pump is extracting and conveying, the pressure changes inside the pigment paste as it enters the conveying pipeline may affect the stability of the pigment paste conveying. Utility Model Content

[0004] The purpose of this application is to provide a pigment paste conveying device that solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a pigment paste conveying device, including a pump housing. A conveying pipe and a feed pipe are fixedly installed on both sides of the pump housing, respectively. A pressure gauge is fixedly installed on the outer wall of the conveying pipe. A pressure regulating shell is installed on the outer wall of the conveying pipe on one side of the pressure gauge. A threaded rod is threaded through the inner top wall of the pressure regulating shell. Guide rods are fixedly installed on the inner top walls of the pressure regulating shell on both sides of the threaded rod. A lifting plate and a piston plate are slidably passed through the outer walls of the two guide rods from top to bottom. A limit block is fixedly installed at the lower end of the guide rod below the piston plate. Springs are sleeved on the outer walls of the two guide rods. The two ends of each spring abut against the lifting plate and the piston plate, respectively. A bearing is fixedly installed at the upper end of the lifting plate.

[0032] Please see Figure 1-5 This application provides a technical solution: a pigment paste conveying device, including a pump housing 1, a conveying pipe 3 and a feed pipe 2 fixedly installed on both sides of the pump housing 1, a pressure gauge 12 fixedly installed on the outer wall of the conveying pipe 3, a pressure regulating shell 4 installed on the outer wall of the conveying pipe 3 located on one side of the pressure gauge 12, a threaded rod 5 threaded through the inner top wall of the pressure regulating shell 4, guide rods 8 fixedly installed on the inner top walls of the pressure regulating shell 4 located on both sides of the threaded rod 5, a lifting plate 7 and a piston plate 10 slidingly passing through the outer walls of the two guide rods 8 from top to bottom, a limit block 11 fixedly installed at the lower end of the guide rod 8 located below the piston plate 10, springs 9 sleeved on the outer walls of the two guide rods 8, the two ends of each spring 9 abutting against the lifting plate 7 and the piston plate 10 respectively, a bearing 6 fixedly installed at the upper end of the lifting plate 7, and the outer wall below the threaded rod 5 embedded in the inner ring wall of the bearing 6;

[0033] In the technical solution of this application, by rotating the threaded rod 5, and with the cooperation of the bearing 6, lifting plate 7, piston plate 10, and spring 9, the pressure inside the pressure regulating shell 4 can be flexibly adjusted according to the changes in the pressure gauge 12, thereby finely adjusting the pressure inside the conveying pipe 3. This effectively addresses the problem of internal pressure changes caused by pump extraction during pigment delivery, maintains stable pressure inside the conveying pipe 3, and avoids unstable pigment flow and delivery interruption caused by pressure fluctuations. This ensures that high-viscosity pigments are accurately, stably, and continuously delivered to the production equipment, meeting the needs of automated production.

[0034] In the technical solution of this application, such as Figure 1 and Figure 2As shown, a mounting plate 13 is welded to the upper end of the pump casing 1. Vertical rods 14 arranged in a rectangular pattern are fixedly mounted on the upper end of the mounting plate 13. A top plate 15 is fixedly mounted on the upper end of the vertical rods 14. A cylinder 16 is fixedly mounted on the upper end of the top plate 15. The telescopic end of the cylinder 16 slides through the top plate 15. A lifting platform 17 is fixedly mounted on the telescopic end of the cylinder 16. The vertical rods 14 slide through the lifting platform 17. The pump casing 1 can fix the mounting plate 13, which in turn fixes the vertical rods 14, which in turn fixes the top plate 15. The top plate 15, in turn, fixes the cylinder 16. The cylinder 16 can drive the lifting platform 17 to move vertically, and the vertical rod 14 can further guide the vertical movement of the lifting platform 17. The upper end of the mounting plate 13 is fixedly installed with a storage cylinder 18, and the lower end of the lifting platform 17 is fixedly installed with a piston rod 19. The piston rod 19 is slidably connected to the inner wall of the storage cylinder 18. The mounting plate 13 can fix the storage cylinder 18, and the lifting platform 17 can drive the piston rod 19 to move vertically. Thus, the piston rod 19 can play the role of piston movement with the cooperation of the storage cylinder 18, thereby facilitating the extraction of pigment paste inside the feed pipe 2 or the discharge of pigment paste to the conveying pipe 3.

[0035] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, end caps 22 are fixedly installed at both ends of the pump casing 1. Positioning plates 27 are welded to the outer walls of the pump casing 1 on both sides away from the end caps 22. The pump casing 1 can fix the end caps 22, and the end caps 22 can seal the pump casing 1.

[0036] In the technical solution of this application, such as Figure 1 , Figure 2 and Figure 5 As shown, a positioning cylinder 23 is fixedly installed on the outer wall of one of the end caps 22. A connecting rod 26 is rotatably connected to the inner wall of the positioning cylinder 23. A valve core 24 is fixedly installed on the inner wall of the connecting rod 26. The valve core 24 is slidably connected to the inner wall of the pump housing 1. The end cap 22 can fix the positioning cylinder 23, while the connecting rod 26 can rotate inside the positioning cylinder 23. Thus, the connecting rod 26 can drive the valve core 24 to rotate, thereby adjusting the flow direction of the pigment paste inside the pump housing 1. The side of the connecting rod 26 away from the valve core 24 is fixed. A swing block 25 is installed, and a U-shaped frame 20 is fixedly installed on the outer wall of the top plate 15. The swing block 25 can be fixed by the connecting rod 26, and the top plate 15 can fix the U-shaped frame 20. An electric push rod 21 is rotatably installed on the inner wall of the U-shaped frame 20. The telescopic end of the electric push rod 21 is rotatably installed on the inner wall of the swing block 25. The U-shaped frame 20 and the swing block 25 can respectively rotate and position the two ends of the electric push rod 21, so that the electric push rod 21 can drive the swing block 25 to rotate.

[0037] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, a U-shaped limit frame 28 is fixedly installed on the outer wall of one of the vertical rods 14 at both ends of the lifting platform 17. The vertical rod 14 can fix the U-shaped limit frame 28, and the U-shaped limit frame 28 can limit the lifting platform 17.

[0038] In use, the extension end of cylinder 16 drives the lifting platform 17 to move vertically along the vertical rod 14. The lifting platform 17 drives the piston rod 19 to slide inside the receiving cylinder 18, thus drawing pigment from the feed pipe 2 into the receiving cylinder 18. Then, the extension end of the electric push rod 21 drives the swing block 25 to rotate. The rotation of the swing block 25 drives the connecting rod 26 and the valve core 24 to rotate. After the valve core 24 rotates, it adjusts the flow direction of the pigment, thereby pressing down cylinder 16 to discharge the pigment from the conveying pipe 3. The pressure gauge 12 on the outer wall of the conveying pipe 3 is observed. It features an integrated dial and pressure sensor. Rotating the threaded rod 5 inside the pressure regulating housing 4 causes the lifting plate 7 to move along the guide rod 8 within the bearing 6. This movement, via the spring 9, drives the piston plate 10 to adjust the pressure inside the pressure regulating housing 4, thereby finely adjusting the pressure inside the delivery pipe 3 to prevent pressure fluctuations from affecting the pigment delivery. The electric push rod 21 extends and retracts. Furthermore, each pigment flow point in this device is equipped with a sealing ring mechanism to ensure the sealing effect of the device. The sealing ring is existing technology and is generally pre-fitted into the outer wall of each component, hence it is not described in detail in this device.
