Description

Technical Field

[0001] This utility model belongs to the field of particle conveying technology, and in particular relates to a dredging structure for an anti-tangling plastic particle conveying pipeline. Background Technology

[0002] Plastic granule conveying pipelines are industrial piping systems specifically designed for the efficient and safe transport of various plastic granules (such as PE, PP, PVC, etc.) in the plastics processing industry. They are typically made of wear-resistant, corrosion-resistant materials with smooth inner walls (such as UHMWPE, stainless steel, or engineering plastics), featuring a compact structure, low resistance, and resistance to clogging. This ensures minimal breakage and residue of granules during transport, improving production efficiency and product quality. This piping system is often used in conjunction with pneumatic conveying, screw conveying, or negative pressure conveying equipment, and is widely applied in injection molding, extrusion, blown film, and other plastic product production lines, forming an important component of modern automated plastics processing.

[0003] For example, Chinese patent CN208567483U discloses a conveying pipe for plastic granules, including an inlet, a straight inlet pipe, a conveying pipe, an outlet, and a mounting bracket. The feed inlet is connected to the feed straight pipe, which is vertically positioned and connected to the conveying pipe. The right side of the conveying pipe slopes downwards, and the right end of the conveying pipe is fixedly connected to the discharge port. The conveying pipe has a rectangular cross-section. A U-shaped air blowing channel is fixed to the lower side of the conveying pipe and welded to both sides. The width of the air blowing channel is the same as the width of the conveying pipe. The air blowing channel and the conveying pipe are separated by the lower side wall of the conveying pipe. The lower side of the conveying pipe is a perforated plate with evenly distributed holes. The diameter of these holes is smaller than the size of the plastic granules. A motor is located below the discharge port and fixed to a mounting bracket. The motor shaft is perpendicularly welded to a hammer-shaped striking rod. The vertically positioned hammer-shaped striking rod strikes the discharge port precisely, causing it to rotate. During the striking process, there is squeezing and collision, causing vibration in the discharge port and the conveying pipe, resulting in excellent material conveying efficiency. The left side of the air blowing channel is connected to the air circuit of the air blowing equipment. This application discloses a conveying pipe for plastic granules, which facilitates the conveying of plastic granules during processing and production. It is especially suitable for transferring pre-dehydrated and air-dried plastic granules into a drying device. It has good conveying effect, small equipment size, low cost, and good practicality.

[0004] The above-mentioned patent has the following problems: In actual use, it does not have a clearing structure. During use, the pipe is easily blocked due to friction, static adsorption or moisture clumping of plastic particles. This will not only cause a significant decrease in conveying efficiency, but may even completely interrupt the flow of materials, affecting the normal production progress and making it difficult for workers to use. In view of this, we propose a clearing structure for anti-tangling plastic particle conveying pipes. Summary of the Invention

[0005] The purpose of this invention is to provide a structure for unblocking a conveying pipe for anti-tangling plastic granules, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a structure for unblocking a conveying pipe for anti-tangling plastic granules, including a conveying pipe body and a base. A guide strip is fixedly connected inside the conveying pipe body, and the guide strip is arranged in a spiral. The base is located below the conveying pipe body. Two fixed plates are fixedly connected to the top of the base. The two fixed plates are rotatably mounted on the same rotating shaft. A cam is fixedly sleeved on the outside of the rotating shaft. A lifting plate is provided on the top of the base. A trapezoidal block is fixedly connected to the bottom of the lifting plate. The cam is adapted to the trapezoidal block. A sliding shell is fixedly connected to the top of the lifting plate. Slider blocks are slidably installed on both sides of the sliding shell, and a striking block is fixedly connected to one side of each of the two sliders. Two sets of fixing components are provided, both of which are located on the outside of the sliding housing and are used to fix the slider inside the sliding housing.

[0007] In this technical solution, the guide strips spirally arranged inside the main body of the conveying pipeline can guide the flow of materials and prevent accumulation, and the universal wheels at the four corners of its bottom facilitate the overall movement; the telescopic rods are slidably installed in the telescopic sleeves at the four corners of the top of the base, the top of the telescopic rods are fixedly connected to the bottom of the lifting plate, and the telescopic sleeves and the telescopic rods are sleeved with springs to form an elastic support structure.

[0008] When unblocking is needed, the motor is started, driving the rotating shaft and cam to rotate continuously. The cam and trapezoidal block work together to make the lifting plate rise and fall back and forth, and the sliding shell moves synchronously with the lifting plate. During the descent of the sliding shell, the striking block generates a knocking vibration on the inner wall of the pipe. Combined with the material guidance of the guide strip, it breaks the entanglement structure of the plastic granules, thus unblocking the pipe. The position of the striking block can be adjusted by sliding the slider inside the sliding shell. The bolt is passed through the through hole on one side of the sliding shell and screwed into the threaded hole on the slider. At this time, the slider is stably fixed inside the sliding shell. With the above structure, the plastic granule conveying pipe can be unblocked, effectively preventing the accumulation and blockage of granules, ensuring smooth material flow, and making it convenient for workers to use.

[0009] Furthermore, in the above technical solution, universal wheels are fixedly installed at the four corners of the bottom of the base.

[0010] In this technical solution, the base can be moved by the omnidirectional wheels.

[0011] In the above technical solution, furthermore, telescopic sleeves are fixedly connected to the top four corners of the base, and telescopic rods are slidably installed inside the four telescopic sleeves. The tops of the four telescopic rods are fixedly connected to the bottom of the lifting plate.

[0012] In this technical solution, the telescopic rod is slidably installed inside the telescopic sleeve, which makes the lifting plate more stable when moving.

[0013] In the above technical solution, the top of the base is provided with four springs, the tops of the four springs are fixedly connected to the bottom of the lifting plate, and the four springs are respectively sleeved on the outside of the four telescopic sleeves and the four telescopic rods.

[0014] In this technical solution, the lifting plate can be made to spring back by using a spring.

[0015] In the above technical solution, further, a support plate is fixedly connected to one side of one of the fixed plates, a motor is fixedly connected to the top of the support plate, and the output shaft of the motor is fixedly connected to one end of the rotating shaft.

[0016] In this technical solution, the support plate ensures that the motor does not idle during operation, and the shaft can be rotated by starting the motor.

[0017] In the above technical solution, a through groove is further provided on the top of the base, and the through groove is located below the cam.

[0018] In this technical solution, the through groove at the top of the base provides space for the cam to rotate, ensuring its adaptive contact with the trapezoidal block.

[0019] In the above technical solution, the fixing component further includes a through hole, one side of which is provided with a sliding shell, and one side of the slider is provided with a plurality of equally spaced threaded holes. A bolt is provided on one side of the sliding shell, and the bolt passes through the through hole and is threaded into the interior of one of the threaded holes.

[0020] In this technical solution, the position of the striking block can be adjusted by sliding the slider inside the sliding shell. The bolt is passed through the through hole on one side of the sliding shell and screwed into the threaded hole on the slider, at which point the slider is stably fixed inside the sliding shell.

[0021] The beneficial effects of this utility model are: 1. The spiral guide strip inside the main body of the conveying pipeline can guide the flow of materials and prevent accumulation. The universal wheels at the four corners of the bottom facilitate the overall movement. The telescopic rod is slidably installed in the telescopic sleeve at the four corners of the top of the base. The top of the telescopic rod is fixedly connected to the bottom of the lifting plate, and the telescopic sleeve and the telescopic rod are sleeved with springs to form an elastic support structure.

[0022] 2. When unblocking is required, the motor is started, driving the rotating shaft and cam to rotate continuously. The cam and trapezoidal block work together to make the lifting plate reciprocate, and the sliding shell moves synchronously with the lifting plate. During the descent of the sliding shell, the striking block generates a knocking vibration on the inner wall of the pipe. Combined with the material guidance of the guide strip, it breaks the entanglement structure of the plastic granules, thus unblocking the pipe. The position of the striking block can be adjusted by sliding the slider inside the sliding shell. The bolt is passed through the through hole on one side of the sliding shell and screwed into the threaded hole on the slider. At this time, the slider is stably fixed inside the sliding shell. With the above structure, the plastic granule conveying pipe can be unblocked, effectively preventing the accumulation and blockage of granules, ensuring smooth material flow, and thus facilitating the use by the staff.

[0042] Working principle: The spiral guide strip 2 inside the main body 1 of the conveying pipe guides the flow of materials and prevents accumulation; the base 3 is located below the main body 1 of the conveying pipe, and the universal wheels 4 at the four corners of its bottom facilitate the overall movement; the telescopic rod 6 is slidably installed in the telescopic sleeve 5 at the four corners of the top of the base 3, and the top of the telescopic rod 6 is fixedly connected to the bottom of the lifting plate 8, and the telescopic sleeve 5 and the telescopic rod 6 are sleeved with springs 7 to form an elastic support structure; the rotating shaft 19 is rotatably installed between the two fixed plates 16 fixed on the top of the base 3, and the cam 20 is fixedly sleeved on the outside of the rotating shaft 19. The cam 20 is adapted to the trapezoidal block 21 at the bottom of the lifting plate 8.

The cam 20 cooperates with the trapezoidal block 21 to make the lifting plate 8 reciprocate up and down, and the sliding shell 9 moves synchronously with the lifting plate 8. During the descent of the sliding shell 9, the striking block 14 generates a striking vibration on the inner wall of the pipe. With the material guidance of the guide strip 2, the plastic granules are broken up and the pipe is unblocked. The position of the striking block 14 can be adjusted by sliding the slider 11 inside the sliding shell 9. The bolt 13 is passed through the through hole 10 on one side of the sliding shell 9 and screwed into the threaded hole 12 on the slider 11. At this time, the slider 11 is stably fixed inside the sliding shell 9.
