Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a position limiting veneer device for a cardboard veneer machine. Background Art

[0002] The veneer machine is a post-printing device that bonds the face paper to the back paper. It can also bond the face paper to the cardboard. The whole machine consists of three parts: an automatic paper feeding system, a laminating mechanism, and a paper pressing unit. Due to the different sizes of cardboards, they are prone to deviation when being transported on the veneer machine's conveying system, so the cardboard needs to be limited.

[0003] Authorization announcement No. CN216235025U discloses a limited veneering device for a cardboard veneering machine, comprising a support frame, rollers are arranged on the left and right sides of the support frame, conveyor belts are arranged on the surfaces of the transmission cylinder and the two groups of rollers, baffles are arranged on the left and right sides of the conveyor belt surface, and a plurality of screw rods penetrating the baffles are screwed on the right side surface of the right baffle, the left end of the screw rod is inserted into the inside of the baffle and movably connected with the baffle, a connecting arm is rotatably connected to the upper part of the front surface of the bracket through a pin shaft, a rotating shaft is arranged on the left end of the connecting arm, a first cylinder is sleeved on the surface of the rotating shaft, and a second cylinder is connected to the surface of the first cylinder through a plurality of groups of springs. The utility model can adjust the distance between the baffle and the baffle according to the width of the cardboard, solves the problem of cardboard offset during the rotation of the conveyor belt, and the second cylinder flattens the cardboard as the conveyor belt rotates to prevent the uneven surface of the cardboard from affecting the aesthetics after veneering.

[0004] The existing cardboard veneer machine has the following disadvantages: when in use, the connecting arm needs to be rotated to adjust the height of the second cylinder according to the thickness of the cardboard, which is troublesome to operate and cannot limit the positions of both sides of the cardboard. Therefore, we propose a cardboard veneer machine with a limited position. Summary of the invention

[0005] The main purpose of the utility model is to provide a position-limiting veneer device for a cardboard veneer machine, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A limited veneering device for a cardboard veneering machine comprises a structural cover, a column and an adjusting screw, wherein internal threaded sleeves are welded through both sides of the structural cover, an adjusting screw is sleeved inside the internal threaded sleeve, a side plate is mounted on one end of the adjusting screw via a bearing, a structural seat is equidistantly fixed on one side of the side plate via bolts, an auxiliary wheel is connected to the inside of the structural seat via a shaft, columns are equidistantly sleeved on both ends of the top of the structural cover, the bottom ends of the columns are connected to a structural frame via a threaded groove, and a rubber roller is mounted on the bottom of the structural frame via a bearing.

[0008] Furthermore, auxiliary rods are connected to both sides of the side plates through threaded grooves, and the auxiliary rods penetrate the structural cover.

[0009] Furthermore, a compression spring is sleeved on the outer side of the column, and the compression spring is located inside the structural cover.

[0010] Furthermore, a tempered glass is embedded on the top of the structural cover, and mounting blocks are welded equidistantly on both sides of the structural cover; the arrangement of the mounting blocks facilitates personnel to fix the structural cover to the transmission system of the veneer machine using bolts.

[0011] Furthermore, the side panels and the structural frame are both located inside the structural cover.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The compression spring on the outside of the column pushes the structural frame downward and presses the rubber roller on the cardboard, which can press it without affecting the movement of the cardboard to prevent the uneven surface of the cardboard from affecting the veneer. The adjusting screw is turned to push the side plate to move through the internal threaded sleeve, so that the multiple auxiliary wheels on one side of the side plate are close to the two sides of the cardboard, which can limit the movement of the two sides of the cardboard without affecting it, preventing the cardboard from shifting during transmission.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3As shown, a limited veneer device for a cardboard veneer machine includes a structural cover 1, a column 2 and an adjusting screw 4. Internal threaded sleeves 3 are welded through both sides of the structural cover 1. The internal threaded sleeves 3 are sleeved with an adjusting screw 4. One end of the adjusting screw 4 is mounted with a side plate 5 through a bearing. A structural seat 6 is equidistantly fixed to one side of the side plate 5 by bolts. An auxiliary wheel 7 is connected to the structure seat 6 through a shaft rod. Columns 2 are equidistantly sleeved at both ends of the top of the structural cover 1. The bottom end of the column 2 is connected to a structural frame 9 through a threaded groove. A rubber roller 10 is mounted on the bottom of the structural frame 9 through a bearing.

[0020] Among them, Figure 3 As shown, auxiliary rods 8 are connected to both sides of the side panels 5 through threaded grooves. The auxiliary rods 8 penetrate the structural cover 1. The setting of the auxiliary rods 8 can improve the structural stability of the side panels 5 without affecting their movement, so that they will not be skewed.

[0021] Among them, Figure 2 As shown, a compression spring 11 is sleeved on the outer side of the column 2, and the compression spring 11 is located inside the structural cover 1. The arrangement of the compression spring 11 can push the structural frame 9 and the rubber roller 10 to move downward.

[0022] Among them, Figure 1 As shown, a tempered glass 13 is embedded on the top of the structure cover 1 , and mounting blocks 12 are welded equidistantly on both sides of the structure cover 1 . The provision of the tempered glass 13 facilitates personnel to observe the movement of the cardboard in the structure cover 1 .

[0023] Among them, Figure 1 As shown, the side panels 5 and the structural frame 9 are both located inside the structural cover 1, which is convenient for limiting the position of the cardboard and pressing the cardboard.

[0024] It should be noted that the utility model is a limited veneer device for a cardboard veneer machine. When working, personnel use bolts to install the structural cover 1 on the transmission system of the veneer machine through the mounting block 12. The compression spring 11 on the outside of the column 2 pushes the structural frame 9 to move down, and presses the rubber roller 10 on the cardboard. It can press the cardboard without affecting its movement to prevent the uneven surface of the cardboard from affecting the veneer. Personnel rotate the adjusting screw 4 to push the side panel 5 to move through the internal threaded sleeve 3, so that the multiple auxiliary wheels 7 on one side of the side panel 5 are tightly attached to the two sides of the cardboard. It can limit the movement of the two sides of the cardboard without affecting it, and prevent the cardboard from shifting during transmission. The setting of the auxiliary rod 8 can improve the structural stability of the side panel 5 without affecting its movement, so that it will not be skewed.
