Description

Technical Field

[0001] The utility model relates to the field of corner pasting machine equipment, in particular to a cardboard double-sheeting prevention mechanism of the corner pasting machine. Background Art

[0002] The corner gluing machine is a device suitable for the top-bottom box model. It is an indispensable main equipment for box making and is used for the production of corrugated cardboard. It is mainly used to fit the four corners of the cardboard. Its principle is to absorb or clamp the corners of the cardboard through the suction cup or clamp of the corner gluing machine, and then press them together through the pressure roller to achieve the fitting of the cardboard corners. In the process of producing paper boxes, the corner gluing machine needs to transport the cardboard. In the process of transporting the cardboard, the material picking mechanism is in the process of downward material picking and sucking the cardboard. Due to the air permeability of some cardboards, when vacuum sucking the cardboard, negative pressure is formed on the second cardboard through the first cardboard, and multiple cardboards are sucked up together, causing material jamming and stopping to affect production. Therefore, in order to avoid the situation where two or more cardboards are sucked at the same time, the present invention proposes a cardboard double-sheet prevention mechanism for the corner gluing machine, so as to ensure that the above situation will not occur each time the cardboard is sucked. Utility Model Content

[0003] The purpose of the present utility model is to solve the shortcomings of the prior art. The cardboard double-sheeting prevention mechanism of the proposed corner laminating machine is characterized in that the anti-double-sheeting serrated pressing devices on both sides form a certain pressure on the side walls of the cardboard under the action of the pressing spring so that the cardboards stacked below are not sucked up at the same time. While the serrated pressing device is pressing, the blowing device blows out compressed gas to destroy the negative pressure between the two cardboards, further separating the cardboard stacked below and the cardboard sucked up by the top material taking mechanism, so that the cardboards at the bottom are not sucked up together, thereby ensuring that the material taking mechanism only takes one cardboard at a time.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The cardboard double-sheeting prevention mechanism of the corner pasting machine includes two anti-deflection limit baffles, the two anti-deflection limit baffles are arranged in parallel, and a limit plate is provided at one end of the top of the two anti-deflection limit baffles, and a through hole is opened in the middle of the two limit plates, and a pressing screw is passed through the through hole of the two limit plates, and the two pressing screws pass through the top of the anti-deflection limit baffles, and the two pressing screws are located at one end of the limit plate. A nut with a size larger than the through hole diameter is provided, and a serrated pressing device is fixedly provided at one end of the two pressing screws near the top of the anti-deflection limit baffle, and an extrusion spring is fixedly provided at the middle of the two pressing screws, and the two ends of the extrusion springs press against the serrated pressing device and the through hole of the limit plate, so that the serrated pressing device has the function of pressing, retracting and resetting;

[0006] With the above technical solution, by arranging a clamping device on the inner side of the anti-deflection limit baffle, when the cardboard is transported to the serrated clamping and pressing device, the serrated clamping device can fix and clamp both sides of the cardboard under the action of the pressing spring.

[0007] Furthermore, the anti-deflection limit baffle is fixedly provided with a blowing device near the sawtooth pressing device, and a plurality of blowing holes are provided on the two blowing devices. The two blowing devices are connected to the air pump to achieve the blowing effect through the air pump;

[0008] Through the above technical solution, air is supplied by an air pump, so that the gas is blown out from the blowing hole of the blowing device. The compressed gas blown out by the blowing device destroys the negative pressure between the two cardboards, further separating the cardboards stacked below and the cardboards sucked up by the material taking mechanism on the top.

[0009] Furthermore, first support blocks are fixedly provided at both ends of the bottom of the two anti-deflection limiting baffles;

[0010] Through the above technical solution, the first support block is used to install the guide rod structure.

[0011] Furthermore, a first mounting cylinder is fixedly provided on each of the four first support blocks, and a guide rod is rotatably provided in each of the two first mounting cylinders at the same end of the two anti-deflection limiting baffles;

[0012] Through the above technical solution, the two guide rods can rotate in the installation cylinder, thereby being used for transporting cardboards.

[0013] Furthermore, a second support block is fixedly provided at the middle of the bottom end of each of the two anti-deflection limit baffles;

[0014] Through the above technical solution, the second support block is used to install the advance and retreat screw.

[0015] Furthermore, a second mounting cylinder is fixedly provided on each of the two second support blocks, and an advance and retreat screw is rotatably provided in each of the two second mounting cylinders. The two advance and retreat screws are driven to rotate by an external motor, and the two driving motors of the two advance and retreat screws are synchronous motors so that the two advance and retreat screws rotate synchronously.

[0016] Through the above technical solution, the two advance and retreat screws are driven by two synchronous motors to push the cardboard to move within the two anti-deflection limit baffles.

[0017] The utility model has the following beneficial effects:

[0018] The cardboard double-sheeting prevention mechanism of the corner pasting machine proposed by the present invention adds an anti-deflection limit baffle in the cardboard feeding mechanism of the corner pasting machine, so that the cardboard will not deviate during transportation. When transported to the blowing device, when the picking mechanism descends and sucks up the cardboard through the vacuum negative pressure suction device, the anti-double-sheeting serrated pressing devices on both sides form a certain pressure on the side walls of the cardboard under the action of the pressing spring, so that the cardboards stacked below will not be sucked up at the same time. While the serrated pressing device is pressing, the blowing device blows out compressed gas to destroy the negative pressure between the two cardboards, thereby further separating the cardboard stacked below and the cardboard sucked up by the picking mechanism on the top, so that the cardboard at the bottom will not be sucked up together, thereby ensuring that the picking mechanism only takes one cardboard at a time.

A nut with a size larger than the through hole diameter is provided at one end of the two pressing screws 9 located on the limit plate 8. A serrated pressing device 11 is fixedly provided at one end of the two pressing screws 9 near the top of the anti-deflection limit baffle 1, and a pressing spring 10 is fixedly provided at the middle part of the two pressing screws 9. The two ends of the two pressing springs 10 are against the serrated pressing device 11 and the through holes of the limit plate 8, so that the serrated pressing device 11 has the function of pressing, retracting and resetting. By providing a clamping device on the inner side of the anti-deflection limit baffle, when the cardboard is transported to the serrated clamping and pressing device, the serrated clamping device can fix the two sides of the cardboard under the action of the pressing spring.

[0028] Reference Figure 2 、 Figure 4 and Figure 5 As shown, the two anti-deflection limit baffles 1 are fixedly provided with a blowing device 12 near the serrated pressing device 11, and a plurality of blowing holes 13 are provided on the two blowing devices 12. The two blowing devices 12 are connected to the air pump to achieve the blowing effect through the air pump, and the air is supplied by the air pump so that the gas is blown out from the blowing holes of the blowing device. The compressed gas blown out by the blowing device destroys the negative pressure between the two cardboards, and further separates the cardboard stacked below and the cardboard sucked up by the material taking mechanism at the top. The bottom ends of the two anti-deflection limit baffles 1 are fixedly provided with a first support block 2, and the first support block is used to install the guide rod structure. The four first support blocks 2 are fixedly provided with a first mounting tube 3, and the two anti-deflection limit baffles 1 are fixed with a first support block 2.

The two advance and retreat screws are driven by two synchronous motors to push the cardboard to move in the two anti-deflection limit baffles.

[0029] Working principle: When the cardboard is transported to the feeding device through the transport device, it enters between the two anti-deflection limit baffles 1, and is transported to the serrated pressing device 11 by the rotation of the two advance and retreat screws 7. The two serrated pressing devices 11 fix the side walls of the cardboard through the squeezing of the extrusion spring 10, thereby fixing the cardboard. At this time, the vacuum feeding device absorbs the top cardboard from the top, and at the same time, the air pump works to blow out gas through the blowing device 12 to destroy the negative pressure between the top cardboard and the bottom cardboard, thereby ensuring that the vacuum feeding device can only absorb one cardboard at a time, thereby achieving the function of preventing double-sheet feeding.
