Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper box production equipment, in particular to a rejecting device for a corrugated paper box production line. Background Art

[0002] Corrugated cardboard is die-cut, embossed, nailed or glued to make corrugated boxes. Corrugated boxes are the most widely used packaging products and have always been the most used of all packaging products. In addition to protecting goods and facilitating storage and transportation, they also play a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products. They are beneficial to the environment and facilitate loading and unloading and transportation.

[0003] During the production process of existing corrugated cardboard boxes, damage and printing errors may occur during the processes of stapling and printing, resulting in defective corrugated cardboard boxes. Defective corrugated cardboard boxes need to be rejected before they are shipped out to ensure that the quality of the products in this batch is good enough. The traditional method is to use a pusher to reject them. When the corrugated cardboard boxes are transported through a conveyor belt, the automated equipment determines whether the corrugated cardboard boxes in the transportation process are qualified. The unqualified ones are pushed to another conveyor belt by a pusher to achieve the rejection effect. This method is easy to cause secondary damage to the corrugated cardboard boxes during rejection. Therefore, a corrugated cardboard production line rejection device is proposed to solve the above-mentioned problems. Utility Model Content

[0030] See also Figures 1-4 , a rejection device for a corrugated box production line, comprising:

[0031] The conveying frame 1 has a material conveying belt 2 disposed therein and includes a frame body 111, a connecting member 112 and a through hole 113, wherein:

[0032] The frames 111 are arranged in a T-shape, and connecting members 112 are provided between the frames 111. The bottom end of the connecting member 112 is provided with a threaded column 114, and the top end of the connecting member 112 is provided with a connecting hole 115 and a through hole 113.

[0033] The material conveyor belt 2 is arranged inside the frame 111;

[0034] Based on the above, the material conveyor belt 2 is an existing belt conveyor, which is an existing technology, so its specific principles are not described here. The T-shaped distribution frame 111 allows the corrugated cardboard boxes to be discharged from different positions during transportation, that is, the material conveyor belt 2 on the same straight line can transport the corrugated cardboard boxes to the next process, and the material conveyor belt 2 protruding from the side allows defective corrugated cardboard boxes to be rejected. The through hole 113 allows the ball 3 to protrude, and the setting of the connecting hole 115 allows the vertical frame 5 to be connected and fixed to the conveying frame 1 through the gasket 6 and the nut.

[0035] like Figure 1 and Figure 5 As shown, the bottom plate 4 is arranged at the bottom end of the connecting member 112, and the bottom plate 4 includes a plate body 41. The upper surface of the plate body 41 is provided with a positioning hole 42 and a hemispherical groove 43. The threaded column 114 passes through the positioning hole 42. The hemispherical groove 43 is provided with a ball 3 inside. The ball 3 passes through the through hole 113 and extends to the outside of the through hole 113.

[0036] The ball 3 is arranged between the connecting member 112 and the bottom plate 4;

[0037] Based on the above, the base plate 4 and the conveyor frame 1 are connected to each other through the cooperation of the threaded column 114 and the nut. At this time, the ball 3 is arranged in the through hole 113 and the hemispherical groove 43, and after passing through the through hole 113, it plays an auxiliary movement role, so that the corrugated cardboard box can move smoothly in different directions on the surface of the ball 3.

[0038] like Figure 1 、 Figure 2 and Figure 6As shown, the stand 5 is arranged above the connecting member 112 and includes a top plate 51 and a guide column 52. The stand 5 includes the top plate 51, the lower surface of the top plate 51 is provided with the guide column 52, the bottom end of the guide column 52 is provided with a threaded rod 53, the threaded rod 53 passes through the connecting hole 115, the diameter of the guide column 52 is larger than the diameter of the threaded rod 53, and the outside of the threaded rod 53 is provided with a gasket 6, the inner diameter of the gasket 6 is smaller than the diameter of the guide column 52;

[0039] an electric push rod 7, which is disposed at the top of the top plate 51;

[0040] Based on the above, the stand 5 is connected and fixed to the conveyor frame 1 by means of gaskets 6 and nuts. At this time, the guide column 52 guides the vertical movement of the movable frame 8, and the electric push rod 7 provides power.

[0041] like Figure 1 、 Figure 2 as well as Figure 7 As shown, the rejecting mechanism is arranged at the output shaft of the electric push rod 7 and includes a movable frame 8, a belt conveyor mechanism 10 and a motor 11;

[0042] The movable frame 8 includes a movable plate 81, a guide hole 82 and a mounting frame 83 are provided on the lower surface of the movable plate 81, the guide column 52 passes through the guide hole 82, an auxiliary spring 9 is provided between the movable plate 81 and the gasket 6, a belt conveyor mechanism 10 is provided inside the mounting frame 83, and a motor 11 is provided outside the mounting frame 83, and the output shaft of the motor 11 is transmission-connected to the belt conveyor mechanism 10;

[0043] Based on the above, the belt conveyor mechanism 10 is composed of a pulley and a conveyor belt, which is an existing technology. The kinetic energy is provided by the motor 11, and the movable frame 8 moves downward under the action of the electric push rod 7, thereby driving the belt conveyor mechanism 10 to move together, so that the belt conveyor mechanism 10 can contact the surface of the corrugated cardboard box, thereby changing the direction of the corrugated cardboard box conveying.

[0044] In actual use of this embodiment, the corrugated cardboard box is transported by the material conveyor belt 2 toward the material conveyor belt 2 at the other end of the same straight line. During the transportation process, the corrugated cardboard box contacts the ball 3 and continues to move under the action of inertia.

[0045] If the corrugated cardboard box at this time is defective, the electric push rod 7 is controlled to move downward, so that the belt conveyor mechanism 10 contacts the surface of the defective corrugated cardboard box. At this time, the motor 11 is energized to drive the belt conveyor mechanism 10 to work, and the corrugated cardboard box moves toward the material conveyor belt 2 at the other end, that is, the effect of rejecting defective products is achieved. In this process, the auxiliary spring 9 plays a role in assisting the vertical movement of the movable frame 8, making the movable frame 8 move more smoothly.

[0046] Compared with the push rod rejection method, this device adopts the friction diversion method, and uses the ball 3 to transport between the material conveyor belts 2, so that the diversion process is as smooth as possible to avoid secondary damage.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
