Description

A paper delivery device of a web cutting machine

technical field

    The utility model relates to a paper cutting device, in particular to a roll paper cross-cutting machine, and more particularly to a paper receiving device of the roll paper cross-cutting machine.

Background technique

Web cutting machine is one of the auxiliary machinery in the printing and packaging industry. It is used to cut the web into sheets of fixed length. It is suitable for longitudinal and transverse cutting of various types of paper, such as gold and silver cardboard, Plain rainbow paper, laser anti-counterfeiting paper, white board paper and various thin paper. The cross-cutting machine of the web generally includes an unwinding device, a feeding device, a cutting device and a paper receiving device. The paper receiving device includes a conveyor table and a paper collection platform. The conveyor table is composed of a transmission roller and a belt running around a transmission roller. Composition, the two ends of the transmission roller are erected on the side wall of the frame, as shown in Figure 1. In the cutting process of roll paper, if there are unqualified printed products or sampling inspection is required, the staff usually picks out or takes samples directly on the conveyor table. Such operations by the staff can easily hinder the paper flow. Normal operation will cause the paper to wrinkle. If the quantity is large or the machine speed is fast, it will easily cause a large amount of waste products and greatly reduce the yield of finished products.

Contents of the invention

In order to overcome the above existing problems, the purpose of this utility model is to provide a paper delivery device of a web cross-cutting machine, which can easily realize sampling detection or waste product picking without affecting the paper operation .

In order to achieve the above purpose, the paper receiving device of the web cross-cutting machine of the present invention includes a conveying machine platform and a paper collecting platform. The conveying machine platform is composed of several horizontally arranged driving rollers and belts. On the side wall of the frame, the characteristic is that there is a moving bracket in the middle of the conveying machine that can move up and down along the side wall of the frame under the control of the cylinder. A vertical slide bar connected at both ends; the belt runs around the transmission roller and the upper and lower guide rollers. When the moving bracket moves up to the highest point, the upper guide roller protrudes from the plane where the transmission roller is located. When the moving bracket moves down to the lowest point, the upper guide roller The roller and the driving roller are in the same plane, and the rear side of the moving support is also provided with a sampling table protruding from the plane where the driving roller is located.

In order to minimize the changes to the frame, the above-mentioned moving bracket moves up and down along the side wall of the frame by the following scheme. The left and right side walls of the frame are provided with vertical chute protruding from the surface of the side wall. The top of the chute is open and can be moved The slide bar of the support is located in the chute, the cylinder is located directly below the chute, and the telescopic arm of the cylinder passes through the bottom wall of the chute and is connected with the bottom of the slide bar.

In order to make the paper run more smoothly, when the above-mentioned mobile support moves up to the highest point, the angle between the plane where the belt on the front side of the mobile support is located and the horizontal plane is preferably 30-45°

In order not to affect the normal paper feeding of the conveying machine, there are mounting blocks extending downward on both sides of the bottom of the sampling platform, and the mounting blocks are fixed on the top of the frame.

For ease of operation, the control switch of the above-mentioned cylinder is located on the control panel of the cross-cutting machine.

The paper receiving device of the web cross-cutting machine of the present utility model is provided with a movable bracket that can move up and down along the side wall of the frame in the middle of the conveying machine table. The moving support moves up to the highest point, and the unqualified printed products or samples automatically enter the sampling platform along the inclined channel formed by the conveying roller and the upper guide roller. The rollers are on the same plane, and the paper passes through the conveying machine and reaches the paper collecting platform. The paper receiving device of the cross-cutting machine of the utility model has simple structure and convenient operation. Waste picking and sampling are carried out automatically on the line, which can avoid paper wrinkling caused by manual picking or sampling on the conveying machine and hindering the paper running, and greatly improves the quality of finished products. It is especially suitable for picking up waste or sampling during the delivery process of the fast cross-cutting machine.

Detailed ways

As shown in Figures 2, 3, and 4, the paper receiving device of the web cross-cutting machine of the present invention includes a conveying machine platform 1 and a paper collecting platform 2, and the conveying machine platform is composed of several horizontally arranged drive rollers 21 and belts 22 The two ends of the drive roller are set on the side wall of the frame 3, and a moving bracket 4 is arranged in the middle of the conveying machine table. The vertical slide bar 43 that two ends are connected is provided with the vertical chute 31 that protrudes from the side wall surface on the left and right side walls of the frame, the top of the chute is open, the slide bar of the mobile support is positioned at the chute, in the chute A cylinder 5 is set directly below the cylinder, and the telescopic arm 51 of the cylinder passes through the bottom wall of the chute and is connected with the bottom of the slide bar. The control switch of the cylinder is located on the control panel of the cross-cutting machine, as shown in Figures 5 and 6. The rear side of the bracket is also provided with a sampling table 6 protruding from the plane where the transmission roller is located. There are mounting blocks 61 extending downward on both sides of the bottom of the sampling table. The mounting blocks are fixed on the top of the frame, and the belt runs around the transmission roller and the upper and lower guide rollers. When the mobile bracket moves up to the highest point, the upper guide roller protrudes from the plane where the transmission roller is located, and the angle between the plane where the belt on the front side of the mobile bracket is located and the horizontal plane is 30-45°, and the mobile bracket moves down to the lowest point When pointing, the upper guide roller and the driving roller are in the same plane.

The paper receiving device of the web cross-cutting machine of the present utility model, during normal use, the movable support moves down to the lowest point, and the fixed-length paper 7 coming out of the cutting device is sent to the paper collecting platform along the direction of the belt. When unqualified printed products or samples need to be inspected, the operator turns on the cylinder switch on the control panel of the cross-cutting machine, and the compressed air moves the movable support up to the highest point through the telescopic arm of the cylinder, and the unqualified printed products or samples move along the conveying roller and the upper The channel formed by the guide roller with an included angle of 30-45° automatically enters the sampling platform.
