Description

Technical Field

[0001] This utility model relates to the field of nylon particles, specifically a flame-retardant nylon particle sorting device. Background Technology

[0002] Flame-retardant nylon granules are modified engineering plastic granules made from ordinary nylon resin by adding functional additives such as flame retardants and processing them through special processes. These granules not only inherit the excellent properties of nylon materials such as high strength, wear resistance, and chemical corrosion resistance, but also have excellent flame-retardant properties, which can effectively inhibit the spread of combustion. They are widely used in fields with high fire safety requirements, such as electronics, automobile manufacturing, and aerospace. As the market's requirements for the quality and purity of flame-retardant nylon granules continue to increase, the importance of the sorting process is becoming increasingly prominent.

[0003] Currently, most common flame-retardant nylon particle sorting devices use vibrating screening technology. This device drives the screening box to generate high-frequency vibration through a vibrating device. Using the screen inside the screening box, the flame-retardant nylon particles are filtered and screened according to their physical characteristics such as particle size and shape, thereby achieving the separation of qualified particles from impurities and unqualified particles to meet production needs.

[0004] However, during the screening process of nylon particles, the nylon particles are very easy to get stuck in the screening holes. Currently, the main method is to use a small-diameter wooden rod to push the stuck nylon particles out of the filter holes. This cleaning method is time-consuming and laborious, resulting in low cleaning efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a flame-retardant nylon particle sorting device to solve the technical problem of low efficiency in cleaning nylon particles stuck in the sieve holes by personnel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant nylon particle sorting device, comprising a base, four sets of springs installed on the top of the base, a sorting box fixed to the top of the springs, a screening plate fixed to the top of the sorting box, multiple sets of screen holes opened inside the screening plate, a screening chamber provided inside the sorting box, a fixing plate installed inside the screening chamber, multiple sets of cleaning columns fixed to the top of the fixing plate, a sliding block connected to the bottom of the fixing plate, a driving rod provided at one end of the sliding block, a rotating block fixed to one end of the driving rod, rotating columns installed on both sides of the rotating block, a moving block sleeved on the outer wall of the rotating block, a moving groove opened on one side of the screening plate, and multiple sets of rotating grooves provided on the inner wall of the moving groove.

[0007] By adopting the above technical solution, the problem of low efficiency in cleaning nylon particles stuck in the sieve holes by personnel is solved. When it is necessary to clean the sieve holes inside the sieve plate, the moving block is pushed to one side of the moving groove. When the moving block is moved to one side of the rotating groove, the rotating block is rotated and pushed into the rotating groove. The rotating block drives the drive rod to rotate synchronously. The drive rod pushes the fixed plate upward through the sliding block, so that the cleaning column is inserted into the sieve hole inside the sieve plate, thereby making the cleaning column knock out the nylon particles stuck in the sieve hole.

[0009] Preferably, the motor drives the centrifugal block to rotate via a rotating rod, and the centrifugal force generated by the centrifugal block causes the sorting box to vibrate.

[0010] The present invention is further configured such that two sets of limiting rods are fixed at the bottom of the sorting box, and limiting posts are sleeved at the ends of the limiting rods.

[0011] Preferably, the limiting column and the limiting rod limit the sorting box, causing the sorting box to vibrate up and down in the vertical direction, so that the screening plate fixed at the top of the sorting box filters and screens the nylon particles.

[0012] The present invention is further configured such that the top end of the sliding block is T-shaped and the bottom of the fixing plate is provided with a groove.

[0013] Preferably, during the rotation of the drive rod, the sliding block slides in the groove, and the drive rod pushes the fixed plate upward through the sliding block.

[0014] The present invention is further configured such that a first limiting block is fixed on one side of the moving block, and a first limiting groove is provided on the inner wall of the screening chamber.

[0015] Preferably, when the moving block moves inside the moving trough, the inner wall of the sorting box limits the movement of the moving block through the first limiting block, so that the moving block can move parallel to the bottom of the screening plate.

[0016] The present invention is further configured such that a second limiting block and a third limiting block are respectively provided on both sides of the fixed plate, and a second limiting groove is provided on the inner wall of the movable block.

[0017] Preferably, when the fixed plate slides up and down, the moving block and the sorting box respectively limit the up and down movement of the fixed plate through the third limit block and the second limit block, so that the fixed plate can move in a direction perpendicular to the screening plate.

[0018] The present invention is further configured such that the inner wall of the screening chamber is provided with a third limiting groove, and the top of the third limiting groove is connected to multiple sets of fourth limiting grooves.

[0019] Preferably, when the fixed plate moves parallel to the bottom of the screening plate, the third limiting groove limits the fixed plate, and when the fixed plate approaches the bottom of the screening plate, the second limiting block on one side of the fixed plate moves inside the fourth limiting groove.

[0020] The present invention is further configured such that a handle is installed on the top of the movable block, and a handle is fixed to the top of the rotating block.

[0021] Preferably, the operator can move the moving block inside the moving slot by pushing it with the handle. In addition, the operator can rotate the pushing handle to make the rotating block rotate and tilt around the rotating column as the center.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention solves the problem of low efficiency in cleaning nylon particles stuck in the sieve holes by setting up a sieve plate, a fixed plate, a cleaning column, a moving block, a rotating block, a drive rod, and a sliding block. When it is necessary to clean the sieve holes inside the sieve plate, the moving block is pushed to one side of the moving groove. When the moving block is moved to one side of the rotating groove, the rotating block is rotated and pushed into the rotating groove. The rotating block drives the drive rod to rotate synchronously. The drive rod pushes the fixed plate upward through the sliding block, so that the cleaning column is inserted into the sieve hole inside the sieve plate, thereby causing the cleaning column to knock out the nylon particles stuck in the sieve hole.

[0024] This invention incorporates a sorting box, spring, limiting post, limiting rod, and vibration assembly. The motor drives the centrifugal block to rotate via a rotating rod. The centrifugal force generated by the centrifugal block causes the sorting box to vibrate. The limiting post and limiting rod installed at the bottom of the sorting box limit the sorting box, causing it to vibrate vertically. This allows the sieve plate fixed at the top of the sorting box to filter and screen nylon particles. Attached Figure Description
