Abstract
Description
Technical Field
[0001] This utility model relates to a block PVC lubricant feeding device, belonging to the field of PVC lubricant feeding technology. Background Technology
[0002] The function of PVC lubricants is to improve the flowability of resin and the release properties of molded products during plastic processing, preventing defects caused by adhesion within the machine or mold. They are generally added to the molding compound or applied to the surface of the mold cavity. Commonly used lubricants include fatty acids and their salts, and long-chain aliphatic hydrocarbons. Based on their mechanism of action, lubricants can be classified as external lubricants and internal lubricants.
[0003] After processing, PVC lubricant needs to be cooled, shaped, and crushed into finished PVC lubricant products. To facilitate material handling, existing PVC lubricants are generally cooled using cooling devices, resulting in PVC lubricant in block form after cooling. The block PVC lubricant after processing needs to be loaded onto trucks or bags via a conveying device. In the current PVC lubricant conveying process, the feeding point is generally fixed, while the loading and bagging positions are often not fixed, making it impossible to flexibly adjust the feeding point according to the loading or bagging position.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] This invention addresses the shortcomings of the prior art by providing a block PVC lubricant feeding device that can flexibly adjust the height and position of the feeding point according to the loading location, and can feed multiple locations simultaneously.
[0006] To solve the above technical problems, the present invention adopts the following technical solution:
[0007] A block PVC lubricant feeding device includes a first screw conveyor and a second screw conveyor, wherein the discharge port at the output end of the first screw conveyor and the inlet port at the feed end of the second screw conveyor are connected by a distribution pipe.
[0008] The upper end of the distribution pipe is fixed to the discharge port at the output end of the first screw conveyor, and the feed port at the feed end of the second screw conveyor is rotatably connected to the distribution pipe through a slewing bearing.
[0009] The rear end of the second screw conveyor is hinged to the base plate. The second screw conveyor is inclined on the base plate and is equipped with an angle adjustment device to adjust the tilt angle of the second screw conveyor.
[0010] Furthermore, the angle adjustment device includes a slide rail mounted on the base plate, a slider slidably mounted on the slide rail, a lead screw connected to the slider by a thread, the lead screw being driven by a second motor, a support rod provided on the slider, the upper end of the support rod being hinged to the outer wall of the second screw conveyor, and the lower end of the support rod being hinged to the slider;
[0011] The bottom of the base plate is also equipped with wheels.
[0012] Furthermore, it also includes a third screw conveyor. The distribution pipe includes a main pipe, a first branch pipe and a second branch pipe that are interconnected, and the three are in a Y-shaped structure. The main pipe is connected to the discharge port at the output end of the first screw conveyor. The first branch pipe is rotatably connected to the feed port at the feed end of the second screw conveyor through a slewing bearing. The second branch pipe is rotatably connected to the feed port at the feed end of the third screw conveyor through a slewing bearing.
[0013] Furthermore, the third screw conveyor is also equipped with an angle adjustment device.
[0014] Furthermore, the axial length of the third screw conveyor is shorter than that of the second screw conveyor.
[0015] Furthermore, valves are installed on both the first and second branch pipe sections; flexible connections are also installed at the feed inlets of the second and third screw conveyors.
[0016] Furthermore, the material distribution pipe also includes a third branch pipe, which is equipped with a discharge pipe and a valve.
[0017] Furthermore, the first screw conveyor is horizontally mounted on the support frame, and a passive pulley is mounted on the shaft of the first screw conveyor. The passive pulley and the driving pulley are driven by a belt. A first motor is also mounted on the support frame, and the first motor drives the driving pulley to rotate through a gearbox.
[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:
[0019] The first branch pipe is rotatably connected to the feed inlet of the second screw conveyor via a slewing bearing, and the second branch pipe is rotatably connected to the feed inlet of the third screw conveyor via a slewing bearing. The second and third screw conveyors can rotate freely via the slewing bearing, allowing the feed inlet position of the screw conveyors to rotate within a certain radius, making the feed point position adjustable. At the same time, both the second and third screw conveyors are equipped with angle adjustment devices, which allows the vertical height of the feed inlet to be adjusted, and the conveying radius of the feed inlet can also be adjusted.
[0020] The material distribution pipe includes a third branch pipe, which is equipped with a discharge pipe. Material can be fed into the bag through the third branch pipe. Therefore, multi-point conveying and feeding can be achieved through the first branch pipe, the second branch pipe and the third branch pipe.

[0033] This utility model also includes a third screw conveyor 14. The distribution pipe 9 includes a main pipe, a first branch pipe 901 and a second branch pipe 902 that are interconnected. The three are in a Y-shaped structure. The main pipe is connected to the discharge port at the output end of the first screw conveyor 1. The first branch pipe 901 is rotatably connected to the feed port at the feed end of the second screw conveyor 13 through a slewing bearing 11. The second branch pipe 902 is rotatably connected to the feed port at the feed end of the third screw conveyor 14 through a slewing bearing 11.
[0034] The third screw conveyor 14 is also equipped with the same angle adjustment device as the second screw conveyor 13. The axial length of the third screw conveyor 14 is shorter than that of the second screw conveyor 13. The second screw conveyor 13 has a higher feeding height and a longer feeding distance than the third screw conveyor 14.
[0035] Valves 10 are provided on the pipe sections of the first branch pipe 901 and the second branch pipe 902; flexible connections 12 are also provided at the feed inlets of the second screw conveyor 13 and the third screw conveyor 14.
