It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Utility Model Content

[0005] The utility model (mainly) aims to provide a chain-driven lifting device to transfer objects from a low place to a high place.

[0006] Therefore, the utility model provides an upward material handling device for a multi-layer rice noodle drying and conveying rack.

The second transmission mechanism is installed behind the feeding start end of the upper powder coating rod conveying assembly to transfer the powder coating rod of the lower powder coating rod conveying assembly to the feeding start end of the upper powder coating rod conveying assembly.

[0010] The upper transition rods are arranged obliquely on both sides of the upper powder coating rod conveying assembly, the upper ends of the upper transition rods are fixed on the frame, and the lower ends extend to the feeding start end of the upper powder coating rod conveying assembly;

[0011] The lower end of the push rod is fixed on the frame, and the upper end is inclined above the upper transition rod, and forms a trumpet-shaped opening with the upper transition rod, the opening of which is toward the upper side of the upper powder coating rod conveying assembly;

[0012] The lower transition rods are inclinedly arranged on both sides of the lower powder coating rod conveying assembly, the lower end of the lower transition rod is fixed on the frame, and the upper end extends to the feeding terminal of the lower powder coating rod conveying assembly; and the lower end of the lower transition rod is provided with the second collision switch.

[0013] Furthermore, it also includes a controller, which is connected to the second drive device and the second collision switch signal.

[0022] The present invention is further described in detail below in conjunction with specific implementations and in conjunction with the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0023] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0024] like Figures 1 to 3 The upper material handling device of a multi-layer rice noodle drying conveyor frame shown in the figure includes a frame and a powder hanging rod conveying device. The frame is a rectangular frame with a plurality of supporting rods arranged inside. The powder hanging rod conveying device is installed on the upper part of the frame. The powder hanging rod conveying device at least includes a lower powder hanging rod conveying assembly 1 and an upper powder hanging rod conveying assembly 8. The lower powder hanging rod conveying assembly 1 is installed below the upper powder hanging rod conveying assembly 8. The feeding directions of the two are opposite, and the powder hanging rods 22 placed on the powder hanging rod conveying assembly are conveyed at a uniform speed. The frame is also provided with an upper material handling device, which transfers the powder hanging rods 22 of the lower powder hanging rod conveying assembly 1 to the feeding start end of the upper powder hanging rod conveying assembly 8.

[0025] The upper material transfer device includes a second driving device, a second collision switch 15, a second transmission mechanism, an upper transition rod 10, a lower transition rod 14, and a push rod 11. The second transmission mechanism is installed behind the feeding start of the upper powder-coating rod conveying assembly 8 to transfer the powder-coating rod 22 of the lower powder-coating rod conveying assembly 1 to the feeding start of the upper powder-coating rod conveying assembly 8. The upper transition rods 10 are arranged obliquely on both sides of the upper powder-coating rod conveying assembly 8. The upper end of the upper transition rod 10 is fixed on the frame, and the lower end extends to the feeding start of the upper powder-coating rod conveying assembly 8; the push rod 11 is arranged obliquely, and its lower end is fixed on the frame, and its upper end is inclined to the upper side of the upper transition rod 10, and forms a trumpet-shaped opening with the upper transition rod 10 opening toward the upper side of the upper powder-coating rod conveying assembly 8. The lower transition rods 14 are arranged obliquely on both sides of the lower layer powder-coating rod conveying assembly 1, the lower end of the lower transition rod 14 is fixed on the frame, and the upper end extends to the feeding terminal of the lower layer powder-coating rod conveying assembly 1. Preferably, the lower end of the lower transition rod 14 is provided with the second collision switch 15. When working, after the lower layer powder-coating rod conveying assembly 1 conveys the powder-coating rod to the specified position, it rolls to the lower end along the upper end of the lower transition rod 14 and abuts against the second collision switch 15, so that the second collision switch 15 obtains the position information of the powder-coating rod. When both ends of the powder-coating rod 22 abut against the two second collision switches 15 on both sides of the lower layer powder-coating rod conveying assembly 1, the second transmission mechanism starts to lift the powder-coating rod 22 and transport it to the feeding starting end of the upper layer powder-coating rod conveying assembly 8.

[0026] Combination Figure 3 The second transmission mechanism is a gantry structure, which includes a first chain transmission assembly, a second chain transmission assembly, and a transmission rod 28. The second driving device and the transmission rod 28 are linked. The driving sprockets of the first chain transmission assembly and the second chain transmission assembly are connected by the transmission rod 28 and are located behind the feeding start end of the upper layer powder hanging rod conveying assembly. In addition, the first chain transmission assembly and the second chain transmission assembly have the same structure, both including a driving sprocket 12, a driven sprocket 16, a chain 13, and a lifting rod piece 24. The driven sprocket 16 is installed directly below the driving sprocket 12 and behind the feeding terminal of the lower layer powder hanging rod conveying assembly. The chain 13 connects the driving sprocket 12 and the driven sprocket 16, and is also fixed with a plurality of lifting rod pieces 24 arranged at intervals. The upper surface of the lifting rod piece 24 is inclined, so that after the lifting rod piece 24 lifts the powder hanging rod 22, the powder hanging rod has a tendency to move to the chain 13 side to avoid falling during the transfer of the powder hanging rod. The second driving device is a second motor.

[0027] The push rod 11 and the upper transition rod form a trumpet-shaped opening. When the lifting rod piece 24 transports the powder-coating rod 22 to the upper powder-coating rod conveying assembly 8, the powder-coating rod 22 gradually separates from the lifting rod piece 22 as the lifting rod piece 24 moves upward after contacting the push rod 11, until it is completely separated and falls to the upper transition rod 10 below, and then transitions to the feeding start end of the upper powder-coating rod conveying assembly through the upper transition rod 10.

[0028] There is a certain distance between two adjacent lifting rod pieces 24, and this distance enables all the lifting rod pieces 24 to lift and transport only one tube powder hanging rod 22 at any time. Specifically, before the powder hanging rod lifted and transported by the lifting rod piece 24 is separated from the lifting rod piece 24, the next lifting rod piece 24 to lift the powder hanging rod has a distance from the powder hanging rod it is about to lift. In this way, it can be ensured that the powder hanging rod on the lower layer powder hanging rod conveying assembly 1 is moved into place before the lifting rod piece 24 lifts and transports the moved powder hanging rod, avoiding the risk of the powder hanging rod falling off due to the lifting of the lifting rod piece 24 before the powder hanging rod is moved into place.

[0029] In the above embodiment, the second collision switch 15 is connected to the controller signal. When the two ends of the powder hanging rod 22 abut against the two second collision switches 15 at the same time, the controller controls the second motor to work for a certain time. This time is enough for the lifting rod piece 24 to lift the powder hanging rod abutting against the two second collision switches at the same time until the powder hanging rod is acted upon by the push rod 11 and is completely separated from the lifting rod piece 24.

[0030] It also includes a second stop switch 17, which is connected to the controller signal and fixed on the frame, preferably between the driven sprocket 16 and the lower layer powder hanging rod conveying assembly 1, and below the lower transition rod 17, for sensing the position of the lifting rod piece. During operation, when the second stop switch 17 senses the position of the lifting rod piece 24, and the two ends of the powder hanging rod 22 do not abut against the two second collision switches 15, the controller controls the second motor to stop. At this time, the lifting rod piece 24 sensed by the second stop switch 15 stops below the lower transition rod 14; when both ends of the powder hanging rod 22 abut against the two second collision switches 15, even if the second stop switch 15 senses the position of the lifting rod piece 24, the controller still controls the second motor 26 to continue to rotate, so that the lifting rod piece 24 lifts the powder hanging rod whose two ends abut against the two second collision switches 15. Preferably, the length of the lifting rod piece 24 is greater than the radius of the powder hanging rod and less than the diameter of the powder hanging rod. The front end of the lifting rod piece 24 extends to the front of the lower apex of the powder hanging rod whose two ends are against the two second collision switches 15. Even if the two powder hanging rods are close together, due to the control of the length of the lifting rod piece 24, the lifting rod piece 24 can only lift the powder hanging rod whose two ends are against the two second collision switches 15.

In addition, many modifications may be made to adapt specific situations to the teachings of the present invention without departing from the central concept of the present invention described herein.
