[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] See Figure 1 and Figure 2 A preferred embodiment of the present invention describes a thermoplastic polyurethane foam particle conveying device, which includes a screw conveyor mechanism 2 and a belt conveyor mechanism 1 disposed below the screw conveyor mechanism 2 for conveying the output particle material. The screw conveyor mechanism 2 is used to stably convey polyurethane foam particle material to the belt conveyor mechanism 1, and the belt conveyor mechanism 1 can prevent the particle material from falling while conveying the particle material.

[0031] The belt conveyor mechanism 1 includes two first support plates 101 arranged opposite each other on the workbench 100. One of the first support plates 101 is provided with a first mounting seat 102, and the other first support plate 101 is provided with a second mounting seat 103. A first power shaft 1021 is rotatably connected to the first mounting seat 102, and a second power shaft 104 is rotatably connected to the second mounting seat 103. A belt 105 is connected between the first power shaft 1021 and the second power shaft 104. The belt 105 can be driven to rotate by the two power shafts.

[0032] Both sides of the first mounting base 102 and the second mounting base 103 are connected by connecting plates 106. Multiple spaced triangular plates 109 are connected between the upper parts of the two opposing connecting plates 106. Two second support plates 111 are positioned in the middle of each triangular plate 109, and fourth support plates 110 and third support plates 112 are positioned on either side of each triangular plate 109. Rollers 113 are connected between the fourth support plate 110 and the second support plate 111, between the two second support plates 111, and between the second support plate 111 and the third support plate 112. Since three rollers 113 are provided on each triangular plate 109, to ensure that the sides of the belt are higher than the middle, the rollers 113 on both sides need to be tilted so that the height of their edges is higher than the height of the other end.

[0033] Specifically, the heights of the fourth support plate 110 and the third support plate 112 are higher than the height of the second support plate 111, thereby enabling the edge of the roller 113 to be higher than the other end.

[0034] The fourth support plate 110 and the third support plate 112 are at the same height to maintain symmetry on both sides, thus making the two support plates at the same height.

[0035] The highest point of the fourth support plate 110 / third support plate 112 is higher than the highest point of the first drive shaft 1021 / second drive shaft 104; the highest point of the second support plate 111 is lower than the highest point of the first drive shaft 1021 / second drive shaft 104. This design ensures that the belt is higher on both sides of the conveyor section than in the middle, allowing the belts on both sides to act as a barrier during conveying, preventing particle materials from falling.

[0036] The end of the second mounting base 103 is also connected to a first discharge port 114 with its opening facing downwards. The bottom of the first discharge port 114 is connected to a second discharge port 115 with its opening facing the side. The first discharge port 114 is used to receive the material conveyed by the belt conveyor mechanism 1, and the second discharge port 115 is connected to other external equipment.

[0037] Two opposing connecting plates 106 are each provided with an adjusting bracket 107 at their lower parts. An adjusting shaft 108 is rotatably mounted on the adjusting bracket 107. The adjusting shaft 108 presses against the belt 105. By adjusting the height of the bracket 107, the tension of the adjusting shaft 108 can be changed.

[0038] The screw conveyor mechanism 2 includes three fifth support plates 201 arranged opposite each other on the workbench 100. An arc-shaped mounting plate 202 is connected to the top of each fifth support plate 201. A circular conveyor cylinder 203 is mounted on the arc-shaped mounting plate 202. End flanges 204 and motor flanges 205 are provided at both ends of the circular conveyor cylinder 203. One end of the circular conveyor cylinder 203 with the end flange 204 is located above the belt conveyor mechanism 1. A motor 206 is mounted on the motor flange 205, and the drive end of the motor 206 is connected to the circular conveyor cylinder 203. The internal conveyor shaft 207 can rotate between two flanges. The conveyor shaft 207 is equipped with helical blades 208, which provide quantitative conveying. A feed inlet 209 is located on the upper part of the circular conveyor cylinder 203 near the motor flange 205. A discharge outlet 212 is installed on the portion of the circular conveyor cylinder 203 above the belt conveyor mechanism 1. The feed inlet 209 is mounted to the circular conveyor cylinder 203 via a feed mounting plate 210, which is also equipped with spaced partitions 211. Foamed particles are fed through the feed inlet 209 and then conveyed to the belt conveyor mechanism 1 via the helical conveyor mechanism 2.

[0039] The working principle of this utility model is as follows:

[0040] The device consists of two parts: a screw conveyor mechanism and a belt conveyor mechanism. The screw conveyor mechanism uses a conveying shaft and its spiral blades inside a circular conveyor cylinder to quantitatively transport foamed particles from the inlet to the outlet, ensuring a stable output of particles. The outlet of the screw conveyor mechanism is located above the belt conveyor mechanism, through which particles are transferred to the belt conveyor mechanism.

[0041] The belt conveyor mechanism is driven by two power shafts to rotate the belt, completing the horizontal transport of particles. The device is designed with a belt conveyor structure where the two sides are higher than the middle. By setting rollers at an incline, the belt forms a groove shape, effectively preventing material particles from falling during transport. The first discharge port at the conveyor terminal receives the particles, while the second discharge port guides the particles to external equipment, completing the entire transport process.

[0042] Furthermore, the belt tension can be adjusted by adjusting the support frame, while the baffles in the screw conveyor mechanism further improve the stability of particle conveying. The entire device has a compact structure, ensuring efficient and safe particle conveying.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
