Description

Technical Field

[0001] The utility model relates to a paper box forming machine, in particular to a separable paperboard suction and delivery device. Background Art

[0002] A carton machine is a specialized device used for the automated forming of cartons. The cardboard conveyor is used to feed individual sheets of cardboard into the forming assembly for the forming process. Traditional cardboard conveying systems utilize a conveyor belt at the bottom of a stacking rack and a paper stop assembly on one side of the stacking rack. The distance between the paper stop assembly and the conveyor belt is greater than the thickness of one cardboard sheet but less than the thickness of two. The friction between the conveyor belt and the bottom cardboard sheet is used to transport the individual cardboard sheets backward. However, this structure suffers from significant friction between the cardboard sheet and the conveyor belt and the penultimate cardboard sheet during transport, potentially scratching the cardboard surface. Furthermore, the penultimate cardboard sheet is also squeezed against the paper stop assembly by friction, potentially causing partial deformation and affecting the subsequent carton forming quality. Alternatively, some systems have been developed that utilize a negative pressure conveyor belt at the top of the paper stack to absorb the cardboard. However, as the top cardboard sheet is sucked and moved backward, it still experiences a certain degree of friction with the second-to-last cardboard sheet, resulting in scratches. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a separable cardboard suction and delivery device for solving the above-mentioned problems.

[0004] To this end, the present invention is implemented by adopting the following scheme:

[0005] A separate cardboard suction and delivery device is characterized in that it includes an upper suction and delivery conveyor belt, the upper suction and delivery conveyor belt is provided with adsorption holes, a negative pressure component is provided corresponding to the upper suction and delivery conveyor belt, a blowing seat is provided below the upper suction and delivery conveyor belt, a cavity is provided in the blowing seat, the cavity is connected to the fan, and blowing holes connected to the cavity are arranged on the blowing seat. Air from the blowing holes can blow the cardboard at the top of the paper pile into an upper and lower separated state, and a paper blocking component is provided on one side corresponding to the blowing seat.

[0006] The blowing holes are arranged to be inclined upward.

[0007] The upper suction conveyor belt extends outwards from the machine base body.

[0008] The paper blocking assembly comprises a paper blocking paper sheet arranged on the paper lifting rack, and the paper blocking paper sheet can position and block the rear side of the paper sheet blown by the blowing seat.

[0009] The above technical solution is a separate cardboard suction and conveying device, which can blow the cardboard at the top of the paper pile into an upper and lower separated state by additionally setting an air blowing seat, and a paper stop assembly is provided on one side of the corresponding air blowing seat to ensure that the front and rear positions of the cardboard will not shift when the air is blown. Since the top cardboard is separated into upper and lower parts, the upper suction and conveying conveyor belt can absorb the top cardboard during the conveying process, and the top cardboard will not come into contact and friction with the lower one, thereby realizing separate suction and conveying of the cardboard, thereby effectively avoiding friction scratches and extrusion deformation between the cardboards, and effectively improving the forming quality of subsequent paper boxes.

[0015] As shown in the figure, the utility model discloses a separate cardboard suction and conveying device, including an upper suction conveyor belt 4, which is provided with adsorption holes, and a negative pressure component 3 is provided corresponding to the upper suction conveyor belt 4. The negative pressure component 3 includes a negative pressure seat, a negative pressure cavity is provided in the negative pressure seat, the negative pressure cavity is connected to the negative pressure machine, and the negative pressure seat has a negative pressure groove connected to the negative pressure cavity. The negative pressure seat can be arranged in multiple arrangements along the moving direction of the upper suction conveyor belt 4. When the adsorption holes of the upper suction conveyor belt 4 move to the negative pressure groove, an adsorption force will be generated to adsorb the cardboard on the upper suction conveyor belt 4, and the cardboard will be sent backward into the forming device as the upper suction conveyor belt 4 moves. A blowing seat 1 is provided below the upper suction conveyor belt 4, and a cavity 5 is provided in the blowing seat 1. The cavity 5 is connected to the fan. Blowing holes 2 connected to the cavity 5 are arranged on the blowing seat 1. The blowing holes 2 can blow the cardboard at the top of the paper pile into an upper and lower separated state. A paper stop assembly is provided on one side of the corresponding blowing seat 1.

[0016] Further, the blowing hole 2 is arranged to be tilted upwards. Adopting this structure, the top cardboard can be blown away to the upper and lower separated states better, and the cardboard on the top can also be blown upwards to fit with the upper suction conveyor belt 4, so that the upper suction conveyor belt 4 can better realize the suction operation.

[0017] Further, the upper suction conveyor belt 4 extends outwards from the base body 7. Adopt this structure, make the layout of the forming device at the rear have larger front and rear adjustment space, also guarantee that the upper suction conveyor belt 4 can send the cardboard into the forming device.

[0018] Furthermore, the paper stop assembly includes a paper stopper 8 disposed on the paper lift 6, which can position and block the rear side of the paper sheet being blown by the air blower 1. With the above structure, when the paper pile is stacked on the paper lift 6 and transported upward to the air blower 1, the paper stopper 8 can support the rear side of the paper sheet when the air blower 1 blows air, ensuring that the front and rear positions of the paper sheet do not shift. Of course, in addition to setting the paper stopper 8 on the paper lift 6, the paper stopper 8 can also be independently set in the frame as needed, as long as it can perform the paper stop function.

[0019] The working principle of the utility model is as follows: when the cardboards are stacked on the paper lifting rack 6 and transported upward to a position close to the upper suction conveyor belt 4, the blowing holes 2 on the blowing seat 1 blow out high-pressure gas to blow the cardboards at the top of the paper pile into an upper and lower separated state. At the same time, the paper board 8 presses the rear side of the cardboard to achieve front and rear positioning. The topmost cardboard is adsorbed by the upper suction conveyor belt 4 and transported backward to the forming device to achieve separate suction and delivery of the cardboards.

[0020] The structure of the utility model realizes the separate suction and delivery of the cardboards, thereby effectively avoiding the friction scratches and extrusion deformation between the cardboards, and effectively improving the molding quality of the subsequent paper boxes.
