Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection, in particular to a transparency detection device for PET polyester chips. Background Art
[0002] A transparency detection device for PET polyester chips is a detection tool used to measure the light transmission ability of polyethylene terephthalate (PET) chips. Such devices are crucial for monitoring and controlling the quality of PET materials during the production process, especially in fields such as manufacturing packaging materials, imaging films, and transparent plastic products. Polyester chips usually refer to polyester raw materials obtained by polymerization production, generally processed into sheet-like particles about 4*5*2 mm in size. During large-scale detection, since these sheet-like particles are randomly stacked together and the height of the random stack is too high, light will undergo multiple reflections and refractions when passing through them. This complex optical interaction results in an inability to accurately measure the overall transparency detection result. Therefore, we propose a transparency detection device for PET polyester chips. Summary of the Utility Model

Detailed implementation mode
[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] Please refer to Figures 1-4 , a PET polyester chip transparency inspection device, including an inspection table 1, a plurality of groups of inspection holes 2 arranged in a matrix are opened at the top of the inspection table 1, a gantry carriage 4 is slidably connected to the top of the inspection table 1, a handle 5 is fixedly connected to one side of the gantry carriage 4, a transparency inspection device 6 is fixedly installed on the side of the gantry carriage 4 away from the handle 5, a drive motor 7 is fixedly installed on the top of the gantry carriage 4, a driving gear 8 is sleeved on the output shaft of the drive motor 7, and further includes:
[0025] A blanking assembly, which is arranged on the gantry carriage 4 and is used to pour polyester chips into the inspection holes 2 for transparency inspection.
[0026] Side grooves 3 are opened on both sides of the inspection table 1, sliding blocks 9 are fixedly connected to the inner walls of both sides of the gantry carriage 4, and the two sliding blocks 9 are respectively slidably clamped in the two side grooves 3. Then, by pulling the handle 5, the gantry carriage 4 can slide in the side grooves 3 through the two sliding blocks 9, so as to move the position of the gantry carriage 4 on the inspection table 1.
[0027] A blanking chute 12 is opened at the top of the gantry carriage 4, and inclined blanking plates 13 are fixedly arranged at the positions close to the top of the inner walls on both sides of the blanking chute 12. The two blanking plates 13 are symmetrically arranged. When in use, first, a plurality of groups of polyester chips are poured into the blanking chute 12 on the gantry carriage 4 through the two blanking plates 13.
[0028] On both inner walls of the gantry carriage 4, rotating rods 10 are respectively installed corresponding to the upper sides of the sliders 9. The end of one set of rotating rods 10 rotates and extends outside the gantry carriage 4 and is sleeved with a driven gear 11. The driven gear 11 meshes with the driving gear 8. Subsequently, the driving motor 7 is started, and the output shaft on the driving motor 7 drives the driving gear 8 to rotate self - clockwise. The driven gear 11 rotates in reverse with the driving gear 8 as the driving gear 8 rotates self - clockwise and drives the rotating rods 10 to rotate on the gantry carriage 4. The transparency detection device 6 detects the transparency of the polyester chips in the detection holes 2 during the movement of the gantry carriage 4.
[0029] On the inner walls of several groups of detection holes 2, cross - shaped anti - dropping frames 17 are fixedly installed. The anti - dropping frames 17 in the detection holes 2 prevent the polyester chips from falling out of the detection holes 2.
[0030] The blanking assembly includes side covers 14, semi - cylinders 15 and spacer blocks 16. At the corresponding ends of the two sets of rotating rods 10, side covers 14 are fixedly connected. Below the blanking chute 12 corresponding to the two side covers 14, two semi - cylinders 15 are fixedly connected. The two semi - cylinders 15 are symmetrically arranged. The distance between the two semi - cylinders 15 is the same as the width of the blanking chute 12. The side covers 14 drive the two semi - cylinders 15 to rotate synchronously with the rotating rods 10 through the rotation of the rotating rods 10. The polyester chips fall into the detection holes 2 through the gap between the two semi - cylinders 15. By rotating the two semi - cylinders 15 during the movement of the gantry carriage 4, the polyester chips in the blanking chute 12 can accurately fall into several groups of detection holes 2 through the spacer blocks 16. Thus, the transparency detection device 6 detects the transparency of the polyester chips in several groups of detection holes 2. Large - batch detection can find and eliminate unqualified polyester chips in the early stage of production, avoid these low - quality products from entering the subsequent production process, thereby reducing the defective rate and improving the overall production efficiency. In addition, by uniformly detecting the light transmittance of the polyester chips, the consistency of the quality of the polyester chips can be effectively monitored.
[0031] The blanking assembly further includes spacer blocks 16. Between the two semi - cylinders 15, multiple groups of spacer blocks 16 are fixedly installed at equal intervals. The spacer blocks 16 separate the polyester chips into groups.
[0032] Working principle: When in use, first pour multiple groups of polyester chips into the material dropping groove 12 on the gantry carriage 4 through two groups of material dropping plates 13. Then start the driving motor 7. The output shaft of the driving motor 7 drives the driving gear 8 to rotate self - clockwise. The driven gear 11 rotates in the opposite direction to the driving gear 8 as the driving gear 8 rotates self - clockwise and drives the rotating rod 10 to rotate on the gantry carriage 4. The side cover 14 drives the two semi - cylinders 15 to rotate synchronously with the rotating rod 10 through the rotation of the rotating rod 10. At this time, pull the handle 5 to make the gantry carriage 4 slide in the side groove 3 through two groups of sliders 9, so as to move the position of the gantry carriage 4 on the inspection table 1. The polyester chips fall into the inspection hole 2 through the gap between the two semi - cylinders 15. The spacer block 16 distributes the polyester chips for each group. The anti - dropping frame 17 in the inspection hole 2 prevents the polyester chips from falling out of the inspection hole 2. The transparency detection device 6 detects the transparency of the polyester chips in the inspection hole 2 during the movement of the gantry carriage 4.

The scope of the present invention is defined by the appended claims and their equivalents.
