Description

Technical Field

[0001] The invention relates to the technical field of polyester chip detection, in particular to a hardness detection device for polyester chips. Background Art

[0002] Polyester chips generally refer to flaky particles made from polyester raw materials obtained through polymerization. Polyester production processes include direct esterification (PTA) and transesterification (DMT). The PTA method has advantages such as low raw material consumption and short reaction time. After polyester production, a hardness tester is required to test the hardness of polyester chips. In the prior art, a hardness testing device for polyester chips is used. When in use, the squeezing rod moves toward the placing rod to squeeze the polyester chips between the two for testing. After squeezing is completed, the polyester chip residue is cleaned by a telescopic cleaning rod. After cleaning, the gear rotates to push new polyester chips into the inclined feeding channel, and then falls into the upper part of the powder trough. The above operation is repeated, thereby avoiding frequent manual placement of tablets and speeding up the tablet hardness testing speed. However, in the actual detection process, first, the polyester chips to be tested need to be added to the placement rod, and then the extrusion rod is moved and squeezed for detection. In this way, the polyester chips are prone to falling during the detection process, and after the detection, the polyester chips on the placement rod need to be cleaned. Only after cleaning can they be reloaded to continue the detection, which greatly reduces the efficiency of the detection work. Therefore, there is room for improvement. Summary of the Invention

[0020] See also Figure 1 、 Figure 4 and Figure 7The feeding structure includes a mounting seat 30 fastened to the top frame 2 at the position of the rear material trough 5, and a mounting plate 31 is installed on the mounting seat 30, and a top plate 35 is provided just above the mounting plate 31.

One end of the extrusion sheet 43 is an arched surface, and the other end of the extrusion sheet 43 is a vertical plane. The four extrusion sheets 43 are spaced apart from the material trough 5. When the rotating disk 4 drives the material trough 5 to rotate to the bottom of the bottom tube 40, the bottom tube 40 is connected to the material trough 5, and the polyester chips stored in the storage bottle 36 can fall into the material trough 5, realizing the automatic feeding function, and the rotating disk When the rotating disk 4 rotates, it drives the squeezing sheet 43 to move to the pressure wheel 42.

[0021] See also Figure 1 、 Figure 4 、 Figure 6 、 Figure 8 and Figure 9 , the driving structure includes an inner groove 44 provided on the rotating disk 4 at the position of each detection strip 45, and a through groove 46 connected to the material trough 5 is provided on the groove wall on one side of the inner groove 44.

A handle 50 is installed on one side surface of the collecting box 47. When the polyester chips in the trough 5 are squeezed and detected, the rotating disk 4 continues to rotate, driving the polyester in the corresponding trough 5 to switch and move toward the collecting box 47. At the same time, it drives one end of the U-shaped rod 51 to slide from the second connecting groove 55 to the second driving groove 54. During this process, the U-shaped rod 51 pulls the detection strip 45 to move in the direction of the rotating column 57, and draws out the detection strip 45 in the trough 5 to open the trough 5, so that the trough 5 is connected with the collecting box 47 through the leakage groove. In this way, the polyester chips can be automatically unloaded into the collecting box 47 for collection after detection, and the automatic unloading function is realized during the detection process.

[0022] The implementation principle of a hardness detection device for polyester chips according to an embodiment of the present invention is as follows: first, the motor 9 is started to drive the rotating rod 10, the chassis 11 and the convex disc 12 to rotate as a whole. When the side surface of the convex disc 12 is pressed against the corresponding concave arc groove 7 on the driving plate 6 and rotates, the driving plate 6 and the rotating disk 4 are limited as a whole. When the chassis 11 drives the driving rod 13 to slide into the radial groove 8 on the driving plate 6, the driving rod 13 squeezes the groove wall of the radial groove 8, pushing the driving plate 6 and the rotating disk 4 to rotate as a whole, thereby realizing the intermittent rotation of the rotating disk 4, and when the rotating disk 4 rotates, it drives the extrusion sheet 43 to move to the pressure wheel 42. The continued rotation of the rotating disk 4 pushes the storage bottle 36 upward through the squeezing of the arc-shaped surface of the squeezing sheet 43 against the pressure wheel 42, and when the squeezing sheet 43 is separated from the pressure wheel 42, the elastic force of the third spring 34 pushes the storage bottle 36 downward to reset, thereby utilizing the up and down movement of the storage bottle 36 to shake the polyester chips stored in the storage bottle 36 up and down, avoiding the problem of clogging of the storage bottle 36 when discharging the material, and ensuring normal loading work. When the feeding trough 5 of the rotating disk 4 rotates to the bottom of the bottom tube 40, the corresponding trough 5 is connected to the bottom tube 40, and the polyester chips to be detected in the storage bottle 36 are discharged into the trough, and then the rotating disk 4 continues 21 , the first spring 18 is compressed, and the movement of the moving bar 16 drives the detection plate 15 to move toward the corresponding material trough 5 on the top frame 2, and squeezes the polyester slices in the material trough 5 to perform hardness detection. When the extrusion wheel 23 is disengaged from the convex block 21, the elastic force of the first spring 18 is used to push the moving bar 16 to drive the detection plate 15 to move in the opposite direction and reset, and one end of the detection plate 15 is removed from the material trough 5. The detection strip 45 is pulled out to prevent the detection plate 15 from interfering with the normal detection work of the rotating disk 4. Then, the rotating disk 4 continues to rotate, driving the polyester chips after detection in the corresponding material trough 5 to move toward the collecting box 47. During the movement, one end of the U-shaped rod 51 is driven to slide from the second connecting groove 55 to the second driving groove 54. During this process, the U-shaped rod 51 pulls the detection strip 45 toward the direction of the rotating column 57, and the detection strip 45 is pulled out from the material trough 5 to open the material trough 5, so that the material trough 5 is connected with the collecting box 47 through the leakage groove. In this way, the polyester chips can be automatically unloaded into the collecting box 47 for collection after detection, and automatic unloading is performed, so that the hardness detection of the polyester chips can be realized.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
