Description

Technical Field

[0001] The utility model relates to the field of polyester resin particle crushing, in particular to a polyester resin particle crushing system. Background Art

[0002] Polyester resin particles are a general term for polymer compound particles formed by the condensation of diols or dibasic acids or polyols and polyacids. Polyester resin particles have high chemical stability, physical properties and processability, and are widely used in plastic products, textile fibers, coatings, electronic materials and other industries. When polyester resin particles are used in different industries, a crusher is needed to perform secondary crushing of the polyester resin particles to refine the volume of the polyester resin particles so that the polyester resin particles meet the use requirements. At present, the devices for crushing polyester resin particles on the market are usually equipped with a rotatable cutter to quickly crush the polyester resin particles. However, when the polyester resin particles are crushed, the cutter will knock some of the polyester resin particles away, and the knocked-away polyester resin particles cannot contact the cutter again in the first time, resulting in some polyester resin particles not being fully and quickly crushed, thereby affecting the crushing efficiency of the polyester resin particles.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-5 The utility model provides an embodiment: a polyester resin particle crushing system, comprising a main box 1:

[0026] The upper cover plate 10 is welded to the upper end of the main body box 1. The lower end of the upper cover plate 10 is rotatably mounted with a rotating spindle 8 through a bearing. The lower end of the rotating spindle 8 is fixedly mounted with a crushing bracket 4. The lower end of the crushing bracket 4 has a plurality of annular cutters 6 in an annular array. The installation of the plurality of annular cutters 6 can enable the plurality of annular cutters 6 to fully crush the polyester resin particles when the rotating spindle 8 drives the crushing bracket 4 to rotate. When the polyester resin particles collide with one of the annular cutters 6 and are knocked away, the polyester resin particles will be shredded by the remaining annular cutters 6, so that the polyester resin particles can quickly re-contact with the annular cutters 6 to ensure that the polyester resin particles are not damaged. To ensure that the polyester resin particles can be fully and quickly crushed, the crushing efficiency of the polyester resin particles is improved, the annular cutter 6 is fixedly connected to the crushing bracket 4, and an air intake fan blade 9 is fixedly installed on the upper end of the outer side of the rotating main shaft 8. The air intake fan blade 9 is installed to rotate to drive the air flow, so that the air blows on the polyester resin particles through the air intake hole 5, so that the polyester resin particles are splashed everywhere, and then the polyester resin particles can quickly contact with the annular cutter 6, thereby improving the crushing efficiency of the polyester resin particles and improving the crushing effect of the device. The air intake fan blade 9 is fixedly connected to the rotating main shaft 8, and a plurality of air intake holes 5 are arranged on the outer side of the crushing bracket 4;

[0027] The material-moving rod 7, whose annular array is at the lower end of the crushing bracket 4, the crushing bracket 4 is fixedly connected to the material-moving rod 7. The installation of the material-moving rod 7 can make the crushing bracket 4 rotate, and the material-moving rod 7 can move the polyester resin particles, so that the polyester resin particles gradually enter the lower end of the annular cutter 6, making the device loading more convenient and simple. The crushing bracket 4 is provided with three, and the upper end of the upper cover plate 10 is rotatably connected to the cover plate bracket 13 through a card slot, and the outside of the cover plate bracket 13 is rotatably connected to the flip screen plate 14 through a hinge. The installation of the flip screen plate 14 can prevent the polyester resin particles from splashing out of the device, thereby ensuring the stability of the device's cutting effect on the polyester resin particles.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A support base 2 is installed at the lower end of the main box 1, and the support base 2 is welded to the main box 1. The upper end ring array of the upper cover plate 10 has four air intake filters 15. Installing the air intake filter 15 can prevent external debris from entering the interior of the device, avoid contaminating the product, and enhance the use effect of the device. The air intake filter 15 is fixedly connected to the upper cover plate 10. A drive motor 16 is fixedly installed on the upper end of the upper cover plate 10. The drive motor 16 is connected to the rotating spindle 8 through a coupling. A discharge pipe 3 is installed at the lower end of the main box 1, and the discharge pipe 3 is welded to the main box 1. The upper end ring array of the upper cover plate 10 has five feed troughs 11, and the upper end ring array of the upper cover plate 10 has four air intake grooves 12.

[0029] The specific use process of the utility model is as follows: the staff adds the polyester resin particles into the device through the feed trough 11, and then drives the motor 16 to drive the rotating main shaft 8 to rotate, so that the rotating main shaft 8 drives the crushing bracket 4 to rotate, and then the material-pickup rod 7 at the lower end of the crushing bracket 4 moves the polyester resin particles entering the main box 1, so that the polyester resin particles slide toward the center of the main box 1, and at the same time, the rotation of the crushing bracket 4 drives the annular cutter 6 to rotate, so that the annular cutter 6 impacts and crushes the sliding polyester resin particles, and some of the polyester resin particles will bounce off. Since a plurality of annular cutters 6 are arranged inside the device, the flying polyester resin particles will hit another annular cutter 6. The rotation of the rotating main shaft 8 will drive the air intake blades 9 to rotate, so that the air intake blades 9 disturb the air, so that the air is blown onto the upper end of the polyester resin particles through the air inlet hole 5, thereby increasing the degree of disorder of the polyester resin particles, so that the polyester resin particles can be evenly cut by the annular cutter 6, and finally the polyester resin particles The device is discharged through the discharge pipe 3. The device is installed with several annular cutters 6 so that when the rotating main shaft 8 drives the crushing bracket 4 to rotate, the several annular cutters 6 can fully crush the polyester resin particles. When the polyester resin particles collide with one of the annular cutters 6 and fly away, the polyester resin particles will be chopped by the remaining annular cutters 6, so that the polyester resin particles can quickly re-contact with the annular cutters 6, ensuring that the polyester resin particles can be fully and quickly crushed, thereby improving the crushing efficiency of the polyester resin particles. The air intake fan blades 9 are installed to rotate to drive the air flow, so that the air is blown onto the polyester resin particles through the air intake holes 5, so that the polyester resin particles are splashed everywhere, and then the polyester resin particles can quickly contact with the annular cutters 6, thereby improving the crushing efficiency of the polyester resin particles and improving the crushing effect of the device. The material shifting rod 7 is installed so that when the crushing bracket 4 rotates, the material shifting rod 7 shifts the polyester resin particles, so that the polyester resin particles gradually enter the lower end of the annular cutter 6, making the device loading more convenient and simple.
