Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically to a sandblasting machine mixing tank anti-clogging device. Background Technology

[0002] Sandblasting machines are widely used in industrial fields such as metal surface treatment and mold cleaning. As a key component of sandblasting machines, the mixing tank is responsible for fully mixing the sand with compressed air before spraying it out. Traditional sandblasting machines use a single stirring structure, which can only stir in a fixed position. This makes it difficult to deal with blockages of different locations and degrees, resulting in limited anti-blocking effects. It is also inconvenient to effectively adjust and treat blockages based on the sand accumulation state. This needs to be optimized. To address the above problems, the inventors have proposed an anti-blocking device for the mixing tank of a sandblasting machine. Utility Model Content

[0003] To solve the above technical problems, the present invention adopts the following technical solution: a sandblasting machine mixing tank anti-clogging device, comprising a support platform, a sandblasting machine body fixedly installed at the top of the support platform, a feed cylinder movably installed at the top of the sandblasting machine body, a fixed frame fixedly installed at the top of the feed cylinder, a telescopic cylinder fixedly installed at the top of the fixed frame, a connecting piece fixedly connected to the output end of the telescopic cylinder, a motor fixedly connected to the bottom end of the connecting piece, a rotating shaft fixedly connected to the drive end of the motor, a cross plate fixedly connected to the bottom end of the rotating shaft, symmetrically distributed first connecting members fixedly installed on the outer side of the cross plate, a first connecting rod rotatably sleeved on the outer side of each of the first connecting members, a second connecting rod slidably connected to one end of each of the first connecting rods, an annular groove opened on the inner side of the feed cylinder, symmetrically distributed ring sliders slidably engaged on the inner side of the annular groove, a second connecting member fixedly connected to one end of each ring slider, and a second connecting member rotatably connected to one end of each of the second connecting rods.

[0004] Preferably, symmetrically distributed support columns are fixedly installed on the upper outer side of the sandblasting machine body, and symmetrically distributed double-layer plates are fixedly installed on the lower outer side of the feed cylinder. One end of the double-layer plate is slidably sleeved on the outside of the support column, and a sliding rod is slidably inserted into one end of each double-layer plate. One end of the sliding rod is slidably inserted into the inside of the support column, and a spring is fixedly connected to one end of each sliding rod. One end of the spring is fixedly connected to the double-layer plate, and a nut is threaded onto the top of each support column. One end of the nut is movably abutting against the double-layer plate.

[0005] Preferably, symmetrically distributed stirring paddles are fixedly installed on the outer side of the first connecting rod.

[0006] Preferably, symmetrically distributed sensors are fixedly installed on the inner side of the feed cylinder.

[0007] Preferably, a pull ring is fixedly connected to one end of each slide rod.

[0008] Preferably, the bottom surface of the support platform is fixedly equipped with an array of casters.

[0009] Preferably, a handle is fixedly installed on one side of the top surface of the support platform.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Through the cooperation of motor, rotating shaft, cross plate, ring slider, annular groove, telescopic cylinder, connecting plate, first connecting piece, first connecting rod, second connecting rod, and second connecting piece, the first and second connecting rods bend to agitate the lower sand material to prevent blockage.

This effectively prevents sand blockage and also has a certain degree of adjustability for handling, making it very efficient and reliable.

[0012] 2. The feed cylinder is positioned by fitting a double-layer plate onto the support column. Then, a spring pulls a sliding rod, which moves and inserts into the support column to position the double-layer plate. Next, a nut is used to install the double-layer plate onto the support column to fix it, thereby securing the feed cylinder. By removing the nut and pulling the sliding rod out of the support column, the feed cylinder can be easily disassembled. This facilitates the inspection and maintenance of multiple components on the feed cylinder and is quite practical. Attached Figure Description

[0020] Symmetrically distributed support columns 25 are fixedly installed on the upper outer side of the sandblasting machine body 11, and symmetrically distributed double-layer plates 26 are fixedly installed on the lower outer side of the feed cylinder 12. One end of the double-layer plate 26 is slidably sleeved on the outer side of the support column 25, and a sliding rod 27 is slidably inserted into one end of each double-layer plate 26. One end of the sliding rod 27 is slidably inserted into the inner side of the support column 25, and a spring 28 is fixedly connected to one end of each sliding rod 27. One end of the spring 28 is fixedly connected to the double-layer plate 26. Nuts 29 are threadedly sleeved on the top of each support column 25, and one end of the nut 29 is movably abutting against the double-layer plate 26.

[0021] By adopting the above technical solution, the feed cylinder 12 is positioned by fitting the double-layer plate 26 onto the support column 25. Then, the slide rod 27 is slid by the spring 28, and the slide rod 27 moves and inserts into the support column 25 to position the double-layer plate 26. Next, the nut 29 is installed on the support column 25 to fix the double-layer plate 26, thereby fixing the feed cylinder 12. By removing the nut 29 and pulling the slide rod 27 out of the support column 25, the feed cylinder 12 can be easily disassembled, which facilitates the inspection and maintenance of multiple components on the feed cylinder 12 and is quite practical.

[0022] Symmetrically distributed agitators 30 are fixedly installed on the outer side of the first connecting rod 20.

[0023] By adopting the above technical solution, the mixing effect of sand is enhanced by setting up the mixing paddle 30.

[0024] Symmetrically distributed sensors 31 are fixedly installed on the inner side of the feed cylinder 12.

[0025] By adopting the above technical solution, two sensors 31 are set to monitor the blockage of the upper and lower parts of the sand material in the feed cylinder 12.

[0026] Each end of the slide bar 27 is fixedly connected to a pull ring 32.

[0027] By adopting the above technical solution, the pull ring 32 facilitates the sliding of the slide bar 27.

[0031] By adopting the above technical solution, the movement direction of the universal wheel 33 can be easily controlled by using the grip 34.

[0032] Working principle: First, during the operation of this device, if sand blockage occurs, the motor 16 is immediately started to control the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 drives the cross plate 18 to rotate. The ring slider 23 slides in the annular groove 22 to cooperate with the rotation of the cross plate 18. At the same time, the telescopic cylinder 14 can be controlled to push the connecting piece 15 down. The connecting piece 15 then pushes the motor 16 and the rotating shaft 17 down, thereby causing the cross plate 18 to drive the first connecting piece 19 down. The first connecting rod 20 rotates on the first connecting piece 19, and the second connecting rod 21 rotates on the second connecting piece 24. One end of the second connecting rod 21 slides on the first connecting rod 20 to perform motion compensation, thereby causing the first connecting rod 20 and the second connecting rod 21 to bend and stir the lower sand to prevent blockage. The telescopic cylinder 14 is controlled to pull the connecting piece 19 down. The connecting piece 15 moves upward, causing the first connecting rod 20 to bend upward in conjunction with the second connecting rod 21 to agitate and prevent blockage of the upper sand material. This effectively prevents sand blockage and also has a certain degree of adjustability for handling specific issues, making it highly efficient and reliable. The feed cylinder 12 is positioned by the double-layer plate 26 fitted onto the support column 25. Then, the slide rod 27 is slid by the spring 28, moving and inserting into the support column 25 to position the double-layer plate 26. Next, the nut 29 is installed on the support column 25 to fix the double-layer plate 26, thereby fixing the feed cylinder 12. By removing the nut 29 and pulling the slide rod 27 out of the support column 25, the feed cylinder 12 can be easily disassembled, facilitating the inspection and maintenance of multiple components on the feed cylinder 12. This is quite practical.
