Description

Technical Field

[0001] The utility model relates to a paper feeding mechanism of a folder gluing machine, belonging to the technical field of printing machinery. Background Art

[0002] A box-gluing machine is a machine that glues and packages various paper boxes. The paper feeding mechanism used in the box-gluing machine delivers the cardboard to each operating station through a conveying mechanism. A row of rollers is set on each side of the conveying mechanism of the existing paper feeding mechanism. When feeding paper, the two sides of the cardboard are slightly against a row of rollers to prevent the cardboard from deviating from the original mechanism. In the existing device, the roller is fixedly installed on the paper feeding device. The distance between it and the cardboard is fixed and cannot be adjusted. During normal movement, the squeezing force between the paper and the roller is within a certain range; however, when blocking the paper, some of the cardboard will deviate too much from the center position, resulting in excessive contact with the roller, and the excessive contact will cause the edge of the cardboard to be crushed. Even after repair, some cardboard will be damaged. Therefore, it is necessary to improve the existing paper feeding mechanism. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a paper feeding mechanism for a folder gluer, which solves the technical problem that when paper is blocked, part of the paperboard deviates too much from the center position, causing excessive contact with the roller, and the excessive contact may cause the edge of the paperboard to be crushed.

[0004] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0005] Solution 1: A paper feeding mechanism of a folder gluing machine, comprising a conveying mechanism, wherein the conveying mechanism comprises a movable conveyor belt and a fixed support member for supporting the conveyor belt; and further comprising:

[0006] A deviation-correcting member arranged on the supporting member: the deviation-correcting member comprises a guide member and a movable member cooperating with the guide member; the guide member is fixedly arranged; the movable member is slidably supported on the guide member; the roller is fixedly installed on the movable member;

[0007] A pair of mutually attracting magnetic blocks; one of the magnetic blocks is fixedly mounted on the movable member, and the other is fixedly mounted on the side of the guide member facing the conveying mechanism; the movable member provides the roller with a resistance that offsets the resistance of the normally moving cardboard through the attraction between the pair of magnetic blocks.

[0008] When blocking paper, if the resistance of the paperboard to the roller exceeds the attraction between the first magnetic block and the second magnetic block, the movable part is separated from the support frame, and the movable part moves along the guide member in the direction away from the conveyor belt to increase the distance between the movable part and the support frame, and as the distance between the movable part and the support frame increases, the attraction between the pair of magnetic blocks also decreases. Therefore, once the resistance between the paperboard and the roller exceeds the resistance during normal movement, the space between the paperboard and the roller increases and the resistance gradually decreases, thereby avoiding that part of the paperboard is damaged or even scrapped due to excessive contact with the roller when blocking paper.

[0009] Preferably, the guide member is a slide rail, and a T-shaped slide groove is provided on the slide rail; the movable member is a T-shaped slider matching the T-shaped slide groove, and the T-shaped slider is slidably installed in the T-shaped slide groove.

[0010] Preferably, the guide member is a guide rod; the movable member is slidably sleeved on the guide rod in a manner that the movable member can only slide along the axial direction of the guide rod.

[0011] Preferably, the guide rod is set as a round rod, and a limiting groove is provided along the axial direction of the guide rod; the movable part is a movable sleeve, and a limiting slider matching the limiting groove is fixedly connected to the inner side surface of the movable sleeve; or a limiting groove is provided on the inner side surface of the movable sleeve along its axial direction, and a limiting slider matching the limiting groove is fixedly connected to the inner side surface of the movable sleeve.

[0012] Preferably, the outer side surface of the guide rod includes at least one corner, and the inner cross section of the sliding sleeve includes an angle matching the corner of the guide rod.

[0013] Solution 2: Based on Solution 1, in order to reduce the moving resistance of the movable part along the guide part, a ball bearing is also provided, specifically:

[0014] Preferably, a ball for reducing movement resistance is rolled on the contact surface between the movable part and the guide part. When the movable part moves along the guide part, the resistance between the guide part and the movable part is rolling resistance, which is smaller than sliding resistance, so the relative movement resistance is reduced. Since the driving force for the movement of the movable part along the guide part is the resistance between the paperboard and the roller, reducing the movement resistance is conducive to reducing the maximum resistance of the roller on the paperboard, and effectively protecting the paperboard from damage.

[0015] The beneficial effects of the utility model are:

[0016] When blocking paper, if the resistance of the paperboard to the roller exceeds the attraction between the first magnetic block and the second magnetic block, the movable part is separated from the support frame, and the movable part moves along the guide member in the direction away from the conveyor belt to increase the distance between the movable part and the support frame, and as the distance between the movable part and the support frame increases, the attraction between the pair of magnetic blocks also decreases. Therefore, once the resistance between the paperboard and the roller exceeds the resistance during normal movement, the space between the paperboard and the roller increases and the resistance gradually decreases, thereby avoiding that part of the paperboard is damaged or even scrapped due to excessive contact with the roller when blocking paper.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0028] In the description of the present invention, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "up", "down", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "end", "head" and "tail" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] like Figure 1-Figure 2 As shown, this embodiment provides a paper feeding mechanism for a folder gluer; it includes a conveying mechanism and two rows of rollers symmetrically fixedly arranged on both sides of the conveying mechanism, the conveying mechanism includes a movable conveyor belt and a fixed support member; it also includes a deviation correction member arranged on the support member:

[0030] The deviation-correcting member comprises a guide member and a movable member cooperating with the guide member; the guide member is fixedly arranged on the support member; the movable member is slidably supported on the guide member; the guiding direction of the guide member is the direction away from the conveyor belt;

[0031] The structures of guide parts and movable parts include but are not limited to the following two situations:

[0032] like Figure 2-Figure 4 As shown, in some other embodiments, the guide member is a slide rail, and a T-shaped slide groove is provided on the slide rail; the movable member is a T-shaped slider matching the T-shaped slide groove, and the T-shaped slider is slidably installed in the T-shaped slide groove. The roller is fixedly connected to the T-shaped slider, and the T-shaped slider can move freely along the T-shaped slide groove. By setting the T-shaped slider to be able to move along the T-shaped slide groove, it can be realized that a T-shaped slider is provided on the T-shaped slide groove, and the T-shaped slider can slide back and forth along the T-shaped slide groove, and under the restriction of the T-shaped slide groove, the T-shaped slider cannot be separated from the T-shaped slide groove.

[0033] In some other embodiments, the guide member is a guide rod, which is fixedly mounted on the support member through a support seat; the movable member is slidably sleeved on the guide rod in a manner that it can only slide along the axial direction of the guide rod. The movable sleeve slides along the guide rod, and the guide rod guides the movable sleeve.

[0034] The structures of the guide rod and the movable sleeve include but are not limited to the following two situations:

[0035] like Figure 5-Figure 7As shown, the guide rod is set as a round rod, that is, the cross section of the guide rod is circular; a limit groove is provided along the axial direction of the guide rod, and a limit slider matching the limit groove is fixedly connected to the inner side surface of the movable sleeve; or a limit groove is provided through the inner side surface of the movable sleeve along its axial direction, and a limit slider matching the limit groove is fixedly connected to the inner side surface of the movable sleeve;

[0036] When the movable sleeve is slidably mounted on the guide rod, the limit slider slides and engages in the limit groove to prevent the movable sleeve from rotating around the guide rod and can only slide back and forth along the axial direction of the guide rod.

[0037] (2) Fig. 9 As shown, the outer side of the guide rod includes at least one corner. For example, the cross section of the guide rod is rectangular or triangular, and the inner side of the sliding sleeve is also rectangular or triangular matching the guide rod. In this case, the sliding sleeve is sleeved on the guide rod and will not rotate, but can only slide back and forth along the axial direction of the guide rod.

[0038] A pair of mutually attractive magnetic blocks are named as the first magnetic block and the second magnetic block, respectively, and the first magnetic block and the second magnetic block are opposite magnetic poles; the first magnetic block is fixedly mounted on the movable part, and the second magnetic block is fixedly mounted on the side of the guide part facing the conveyor belt; the movable part provides the roller with a resistance that offsets the resistance of the normally moving cardboard through the attraction between the first magnetic block and the second magnetic block. In the normal moving stage, the movable part is stably fixed in the initial position through the attraction between the pair of magnetic blocks, and the magnetic attraction is used to balance the resistance of the cardboard to the roller, so as to realize the deviation correction of the roller to the cardboard. And the attraction between the first magnetic block and the second magnetic block is within the resistance range, and will not cause damage to the edge of the cardboard. When blocking paper, if the resistance of the cardboard to the roller exceeds the attraction between the first magnetic block and the second magnetic block, the movable part is separated from the support frame, and the movable part moves along the guide member in the direction away from the conveyor belt to increase the distance between the movable part and the support frame, and as the distance between the movable part and the support frame increases, the attraction between the pair of magnetic blocks is also reduced. Therefore, once the resistance between the cardboard and the roller exceeds the resistance during normal movement, the space between the cardboard and the roller will increase and the resistance will decrease, thereby avoiding that part of the cardboard will be damaged or even scrapped due to excessive contact with the roller when the paper is blocked.

[0039] like Figure 4 and Figure 8 As shown, in some other embodiments, the contact surface between the movable member and the guide member is rolled with a ball for reducing resistance. For example, a ball is rolled on the bottom surface where the sliding block contacts the guide slot, and a ball is rolled on the contact surface between the movable sleeve and the guide rod. When the sliding block moves along the guide slot or the movable sleeve moves along the guide rod, the movement resistance is small.

[0040] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
