[0016] Therefore, compared with the prior art, the present invention has the following advantages:

[0017] (1) This utility model uses a combination of heat insulation shell and heating element to heat the plastic raw material in the conveying cylinder. The heat insulation shell can effectively reduce heat loss and concentrate heat around the conveying cylinder. The heating element can apply heat to the raw material evenly from multiple directions, avoiding uneven heating of the raw material due to local overheating or overcooling. This makes the quality of the material after hot melting more stable, thereby effectively improving the product quality of plastic fruit baskets and reducing the defect rate caused by quality problems.

[0036] like Figure 1 , 2 As shown in Figure 3, this utility model provides another technical solution: a hot-melt device for manufacturing plastic fruit baskets. The difference from embodiment 1 is that rollers 11 are bolted to the four corners of the bottom of the frame 1, and an adjustable support 12 is provided at both the left and right ends of the bottom of the front and rear sides of the frame 1. The frame can be raised and lowered by the adjustable support 12, thereby realizing the movement or placement of the entire device. Example

[0037] like Figure 1 , 4As shown, this utility model provides another technical solution: a hot-melt device for manufacturing plastic fruit baskets. The difference from embodiment 1 is that the feeding device consists of a feeding bucket 13 and an adjustment mechanism set at the lower end of the feeding bucket 13. The upper end of the feeding bucket 13 is cylindrical and the lower end is funnel-shaped. The top of the feeding bucket 13 is provided with a cover plate 14 with a handle.

The upper connecting plate 15 and the lower connecting plate 16 are fixed together by bolts. Example

[0039] like Figure 1 , 8 As shown, this utility model provides another technical solution: a hot-melt device for manufacturing plastic fruit baskets. The difference from embodiment 1 is that the outer wall of the spiral auger 4 is welded with spiral blades 21, and the gap between the spiral auger 4 and the inner wall of the conveying cylinder 3 gradually narrows, generating a force that moves towards the discharge port 10, thereby improving the extrusion efficiency and forming a continuous flow of molten material for subsequent weaving processes. Example

[0040] like Figure 1 , 7 As shown, this utility model provides another technical solution: a hot-melt extrusion device for manufacturing plastic fruit baskets. The difference from Embodiment 1 is that the above-mentioned position adjustment device includes a mounting base 23, a rotating rod 24, a fixing rod 25, and an adjusting ring 26. The mounting base 23 is installed on the right side wall of the box body 2 by bolts. Rotating holes 27 are provided at both ends of the rotating rod 24. One end of the rotating rod 24 is rotatably connected to the mounting base 23 through a rotating shaft 28, and the other end of the rotating rod 24 is rotatably connected to the lower end of the fixing rod 25. The upper end of the fixing rod 25 is welded and fixed to the lower end of the adjusting ring 26. By rotating the adjusting ring 26 and / or the rotating rod 24, the discharge angle of the hot-melt extrusion device can be adjusted.

[0041] The plastic fruit basket manufacturing hot-melt device provided by this utility model first pours the plastic raw material into the feeding bucket 13 and covers it with the cover plate 14 to prevent external impurities from mixing into the raw material and affecting the product quality. According to the feeding speed required by the production process, the operator can precisely control the feeding amount by adjusting the position of the adjusting plate 17 in the adjusting mechanism at the lower end of the feeding bucket 13 in the slide groove 19.

[0042] The drive motor 7 is started, and the power of the drive motor 7 is transmitted to the screw conveyor 4 after the speed is adjusted by the reducer 8, so that it starts to rotate in the feeding cylinder 3. At the same time, the heating element 6 on the outer wall of the feeding cylinder 3 starts to work. With the cooperation of the heat preservation shell 5, the plastic raw material in the feeding cylinder 3 is heated evenly. As the screw conveyor 4 rotates, the plastic raw material put into the feed port 9 by the feeding device is gradually heated and melted in the feeding cylinder 3. Under the push of the screw conveyor 4, it is extruded from the discharge port 10 along the feeding cylinder 3 to form strip material for manufacturing plastic fruit baskets, and then enters the subsequent weaving process.

[0043] When the equipment needs to be moved, the rollers 11 at the bottom of the frame 1 are used to push the equipment to the new production location. After arriving at the destination, the adjustable supports 12 on both sides of the bottom of the frame 1 are adjusted to make them in close contact with the ground and bear the weight of the equipment, ensuring that the equipment is stable and does not shake during operation.

[0044] During equipment operation, the heat dissipation mesh 22 at the bottom of the housing 2 continuously plays a role in dissipating excess heat inside the housing 2, maintaining the internal temperature balance of the equipment, and ensuring the normal operation of all components. If it is necessary to make fine adjustments to the discharge position to better connect with other production equipment, the operator can do so through the adjustment ring 26 and rotating rod 24 in the operation position adjustment device, ensuring the efficient and smooth operation of the entire production process.
