Description

Technical Field

[0001] This utility model relates to the field of paper packaging machine technology, and in particular to a paper conveying line structure. Background Technology

[0002] A paper packaging machine is a device used in the process of packaging goods in cartons. The paper stack moves along a paper-slitting conveyor line. When the paper stack passes the paper-slitting mechanism, the friction between the surface of the paper-slitting conveyor line and the bottom cardboard of the paper stack is used to separate the bottom cardboard sheets one by one. Because cardboard materials, surface smoothness, and hardness vary, and existing paper-slitting conveyors are usually not adjustable, when the friction between the surface of the paper-slitting conveyor line and the surface of the cardboard is less than the friction between the cardboard sheets themselves, the cardboard will slip between the conveyor line and the paper-slitting conveyor line, preventing stable separation. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a paper conveying line structure that can change the friction between the paper and the cardboard by adjusting the angle, thereby improving the paper separating stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A paper conveying line structure includes a conveying line body and a conveyor belt disposed on the conveying line body. One end of the conveying line body is provided with a main shaft and a power assembly for driving the main shaft to rotate. Both ends of the main shaft are rotatably connected to a frame. An angle adjustment mechanism for adjusting the tilt angle of the conveyor belt is provided on the conveying line body between the opposite end of the main shaft and the frame.

[0006] By adopting the above technical solution: when the paper stack is conveyed along the conveyor belt to the paper blocking mechanism, the paperboard is separated by the friction between the conveyor belt and the paperboard at the bottom of the paper stack. In this structure, the tilt angle of the conveyor belt can be adjusted by the angle adjustment mechanism to adjust the force between the conveyor belt and the paperboard (the resultant force of friction and thrust), thereby meeting the separation of different paperboards, with stronger versatility and better stability.

[0007] Preferably, the angle adjustment mechanism includes a rotating sleeve and a support fixed on the rotating sleeve. The rotating sleeve is rotatably connected to the conveyor body, and the support is fixedly connected to the frame and its fixed position can be adjusted.

[0008] Preferably, the support is configured as a screw, and the screw is provided with a plurality of nuts. The lower end of the screw passes through the frame and is locked by the nuts.

[0009] As preferred, the conveying line body comprises several parallel conveying assemblies, several connecting rods connecting the conveying assemblies, all the conveying assemblies sharing a main shaft, the conveying belts on each conveying assembly are independently configured, and two adjacent conveying assemblies are arranged at intervals. The multiple sets of parallel and interval arranged conveying assemblies are used for supporting and conveying the paper stack, so that there are more contact points between the lowermost paperboard of the paper stack and the conveying assemblies, the friction between the conveying assemblies and the paperboard is increased, and the lowermost paperboard is more stable in separation.

[0010] As preferred, the upper surface of the conveying belt is configured as an arc surface with a middle high and two ends low. Since the paperboard has a certain flexibility, the flexibility can adapt to the arc surface of the conveying belt, and the acting force (the combined action of friction and thrust) between the conveying belt and the paperboard is further improved.

[0011] As preferred, the bottom of the conveying line body is provided with a cleaning mechanism for cleaning the conveying belt. Due to the friction between the paperboard and the conveying belt, paperboard debris powder will be left on the conveying belt, which will affect the friction between the conveying belt and the paperboard. The cleaning mechanism is used for regularly cleaning the conveying belt to remove the paperboard debris powder on the conveying belt, so as to maintain the acting force between the conveying belt and the paperboard, and ensure the stable separation of the paperboard.

[0012] As preferred, the cleaning mechanism comprises a cleaning assembly rotatably connected with the connecting rod and a cleaning power for driving the cleaning assembly to rotate around the connecting rod. In a first state, the cleaning power drives the cleaning assembly to rotate upward to contact the lower surface of the conveying belt. In a second state, the cleaning power drives the cleaning assembly to rotate downward to separate from the lower surface of the conveying belt.

[0013] As preferred, the cleaning assembly comprises a brush and connecting arms fixed at both ends of the brush, the connecting arms are rotatably connected with both ends of the connecting rod, and the cleaning power is configured as a cylinder, the shaft end of the cylinder is connected with the connecting arm.

[0014] As preferred, the cleaning mechanism is configured as two sets, and the two sets of cleaning mechanisms are arranged at the lower sides of both ends of the conveying line body.

[0015] Therefore, the utility model has the beneficial effects of adjusting the friction between the conveying belt and the paperboard and improving the stability of paper separation. BRIEF DESCRIPTION OF DRAWINGS
