Description

Technical Field

[0002] Degradable TPU masterbatch is a TPU masterbatch obtained by adding a certain amount of starch during the production process. The production process of degradable TPU masterbatch is: pour the raw materials into the extruder, mix and melt, and then extrude TPU strips, and then pull the TPU strips to the cooling device for cooling, and then enter the pelletizer for pelletizing after cooling, so as to obtain the required degradable TPU masterbatch.

[0003] The prior art discloses an air cooling device for producing degradable TPU masterbatch with patent announcement number CN215750682U. The patent includes a conveyor frame formed by splicing a plurality of unit brackets, a conveyor belt installed on the conveyor frame, and a driving mechanism for driving the conveyor belt. The joints between adjacent unit brackets are covered with connecting plates. The connecting plates corresponding to the adjacent unit brackets are connected with bolts. The bolts pass through the connecting plates and are connected with the corresponding unit brackets. A blowing device is installed on the unit bracket. The air outlet of the blowing device faces the conveyor belt. The present application is adapted to the cooling problem of TPU material strips during the production of degradable TPU masterbatch. However, the following deficiencies still exist in actual use: from a practical point of view, when the device air cools the TPU masterbatch, the air cooling position remains unchanged, resulting in poor air cooling uniformity within a certain range, which leads to poor air cooling effect and reduced air cooling efficiency. At the same time, the TPU masterbatch cannot be regularly circulated and flipped during the air cooling process, resulting in poor air cooling efficiency and difficulty in quickly achieving air cooling.

[0004] Therefore, there is a need for an air cooling device for producing antibacterial grade TPU to solve the problems in the prior art that the air cooling position cannot be adjusted and the TPU masterbatch cannot be turned over. Utility Model Content

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the reciprocating assembly 62 includes a first gear 621, which is fixedly connected to the front fixed shaft 613, and the lower part of the first gear 621 is fixedly connected to a fixed seat 622 on the fixed frame 611, and a slide groove 623 is provided on the fixed seat 622 corresponding to the first gear 621, and a rack 624 is slidably arranged in the slide groove 623 and meshes with the first gear 621, and a connecting plate 626 is fixedly connected to the rack 624, and a first electric telescopic rod 625 is fixedly connected to the connecting plate 626 and fixedly installed on the upper part of the fixed seat 622.

[0028] When in use, the fan 615 is operated to achieve air cooling of the TPU material, and at the same time, the first electric telescopic rod 625 is operated to push the connecting plate 626 to drive the rack 624 to slide in the slide groove 623, so that the rack 624 drives the first gear 621 to rotate, and then the first gear 621 drives the fixed shaft 613 to rotate, so that the installation frame 614 rotates on the upper part of the fixed frame 611, thereby achieving the adjustment of the air outlet direction of the fan 615 to improve its air cooling uniformity, and then improve the air cooling efficiency. At the same time, the reciprocating extension and retraction of the first electric telescopic rod 625 can achieve the reciprocating rotation of the installation frame 614, further improving the air cooling uniformity.

[0029] According to the above working process, it can be known that: through the air cooling mechanism 6, when the installation component 61 cooperates with the reciprocating component 62, the air cooling position can be reciprocated, thereby improving the uniformity of the air cooling effect in its air cooling area, and then improving the air cooling efficiency of the TPU material, thereby improving production efficiency.

[0030] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the flip mechanism 7 includes two connecting frames 701, the two connecting frames 701 are respectively connected to the connecting seat 3 and are symmetrically arranged on the conveying device 1 front and back, a fixed plate 703 is fixedly connected in the connecting frame 701, a slide bar 702 is slidably connected to the fixed plate 703, a limited block 704 is fixedly connected to the slide bar 702 at the fixed plate 703, a tooth groove 705 is arranged at the bottom of the limit block 704, a second gear 706 is meshed at the lower part of the tooth groove 705, a connecting shaft 707 is fixedly connected to the second gear 706, and the connecting shaft 707 is fixedly connected to the second gear 706.

At this time, the mounting seat 5 slides on the slide seat 4 to adjust the position of the air cooling mechanism 6. At the same time, the fan 615 is operated to realize air cooling of the TPU material. At the same time, the first electric telescopic rod 625 is operated to push the connecting plate 626 to drive the rack 624 to slide in the slide groove 623, so that the rack 624 drives the first gear 621 to rotate, and then the first gear 621 drives the fixed shaft 613 to rotate so that the mounting frame 614 rotates on the upper part of the fixed frame 611, thereby realizing the adjustment of the air outlet direction of the fan 615 to improve its air cooling uniformity and thus improve the air cooling efficiency. At the same time, the reciprocating extension and retraction of the first electric telescopic rod 625 is used to realize the reciprocating rotation of the installation frame 614, thereby further improving the uniformity of air cooling. In the process of air cooling the TPU material, the second electric telescopic rod 709 is used to push the sliding rod 702 and the Forbidden City fixed plate 703 to slide in the connecting frame 701, thereby driving the limit block 704 to move, and the tooth groove 705 set at the bottom of the limit block 704 is used to mesh and rotate the second gear 706, so that the second gear 706 drives the connecting shaft 707 to rotate, thereby realizing the rotation of the flip plate 708. The TPU material is flipped by the rotation of the flip plate 708, so that the TPU material can be fully air-cooled, and the air cooling efficiency is further improved.
