[0027] The existing rubber wheel glue breaking mechanism of the side rubber coating machine has many technical problems in actual application. When the traditional mechanism performs side rubber coating and glue breaking operation, it is usually difficult to realize accurate and stable conversion between rotary motion and linear motion. Under high-speed coating working condition, the inaccuracy of such conversion is particularly obvious, which is easy to cause deviation of the opening and closing action of the shutter.

[0028] In addition, due to the instability of motion conversion in the running process of the traditional mechanism, the problem of up and down shaking is also easy to appear, and the shaking will further aggravate the inaccuracy of the opening and closing action of the shutter, reducing the reliability and stability of the mechanism.

[0029] In view of the above technical problems, such as Figs. 1 to 3The embodiment provides a rubber wheel rubber breaking mechanism of a side rubbering machine, which comprises a guide block 2 arranged on one side of a side rubbering wheel 1, the guide block 2 is provided with a guide hole, and an axially movable push rod 3 is arranged in the guide hole; the front end of the push rod 3 is provided with a shutter 4, the rear end is connected with a first blocking plate 5 and a second blocking plate 6, an active plate 7 is arranged between the first blocking plate 5 and the second blocking plate 6, the middle part of the active plate 7 is provided with a through slot 701, and the push rod 3 penetrates through the through slot 701; the push rod 3 is provided with a waist slot 8 in the axial direction, two pin shafts 9 are arranged in the waist slot 8, the two sides of the active plate 7 are respectively provided with positioning grooves 702, the two pin shafts 9 are respectively clamped into the two positioning grooves 702, and one of the pin shafts 9 is in abutment with the first blocking plate 5, and the other pin shaft 9 is in abutment with the second blocking plate 6; the active plate 7 is connected with a rotating block 10, the rotating block 10 is connected with a rotating shaft 11, the rotating shaft 11 is rotationally connected with a rack support plate 12, and the rotating shaft 11 is connected with a rotary driving device 18.

[0030] In the book block gluing process, the lower side of the book block is driven by a moving tool to pass between two side rubbering wheels, and the side rubbering wheels are used to glue the two sides of the book block back ridge by the hot melt glue attached thereto, so as to be matched with the next book cover.

[0031] When the book block needs to be glued, the rotary driving device 18 drives the rotating shaft 11 to rotate forward by a predetermined angle, the rotating shaft 11 drives the rotating block 10 to rotate synchronously, and the rotating block 10 further drives the active plate 7 to rotate forward around the axis of the rotating shaft 11. During the rotation of the active plate 7, the positioning groove 702 arranged thereon is matched with the pin shaft 9 in the waist slot 8 of the push rod 3, and the first blocking plate 5 is pushed to move backward. The first blocking plate 5 drives the shutter 4 to move backward through the push rod 3, so that the shutter 4 is completely separated from the side surface of the side rubbering wheel 1. At this time, the hot melt glue brought by the rotation of the side rubbering wheel 1 can move to the side surface of the book block smoothly, and side gluing is realized.

[0032] When the gluing needs to be stopped, the rotary driving device 18 drives the rotating shaft 11 to rotate reversely by a predetermined angle, the rotating shaft 11 drives the rotating block 10 and the active plate 7 to rotate reversely synchronously. During the rotation of the active plate 7, the positioning groove 702 on the other side thereof is matched with the other pin shaft 9, and the second blocking plate 6 is pushed to move forward. The second blocking plate 6 drives the shutter 4 to move forward through the push rod 3, so that the shutter 4 is completely in contact with the side surface of the side rubbering wheel 1. At this time, the shutter 4 blocks the hot melt glue from moving to the side surface of the book block with the side rubbering wheel 1, and the gluing is broken.

[0033] The above embodiment realizes the hinged connection of the movable plate 7 and the push rod 3 by arranging the waist groove 8 on the push rod 3, arranging two pin shafts 9 in the waist groove 8, and arranging the corresponding positioning groove 702 on the movable plate 7. The rotation driving device 18 drives the rotation shaft 11 to rotate forward and backward in a small range, drives the movable plate 7 to swing forward and backward in a small range, and then transmits the swing to the push rod 3 through the movable pin shaft 9, so as to realize the accurate conversion of the rotation and the linear motion, avoid the up and down swing problem that may occur in the traditional mechanism, make the opening and closing action of the shutter 4 more accurate and stable, and be especially suitable for the high-speed gluing working condition.

[0034] In some embodiments, the cross section of the rotation shaft 11 is polygonal, and the rotation block 10 is provided with a corresponding polygonal insertion hole, and the rotation shaft 11 is inserted into the insertion hole.

[0035] When the rotation driving device 18 drives the rotation shaft 11 to rotate, the torque can be directly and effectively transmitted from the rotation shaft 11 to the rotation block 10 due to the polygonal cooperation between the rotation shaft 11 and the insertion hole of the rotation block 10. The rotation block 10 rotates and further drives the swing of the movable plate 7, and finally realizes the opening and closing action of the shutter 4. The polygonal cooperation avoids the slippage that may occur in the cooperation between the traditional circular shaft and hole, and ensures the stability and reliability of the torque transmission.

[0036] In some embodiments, the push rod 3 is a lead screw, the push rod 3 is connected with a first nut 13 and a second nut 14, the first nut 13 is arranged at the rear end of the first blocking plate 5 and abuts against the first blocking plate 5, the second nut 14 is arranged at the front end of the second blocking plate 6, a buffer spring 15 is arranged between the second blocking plate 6 and the second nut 14, and the buffer spring 15 is sleeved on the push rod 3.

[0037] When the movable plate 7 swings forward, the push rod 3 is pushed to axially displace forward, and then drives the shutter 4 to approach the side rubber wheel. After the shutter 4 contacts the side rubber wheel, if the movable plate 7 continues to swing forward, the buffer spring 15 will be compressed, thereby playing a buffering role, avoiding the continuous forward movement of the push rod 3 from causing excessive extrusion on the side rubber wheel, and avoiding damage to the side rubber wheel or each rotating part.

[0038] In some embodiments, one side of the movable plate 7 is provided with an opening connected with the through groove.

[0039] When the mechanism operates, the movable plate 7 will swing, at this time, the opening can provide the push rod 3 with a necessary movement channel and a avoiding space, so that the push rod 3 does not interfere with the movable plate 7 in structure when axially moving along with the action of the mechanism. At the same time, during the installation process, the movable plate 7 can be directly sleeved on the push rod 3 through the opening, and then the positions of the first blocking plate 5 and the second blocking plate 6 are adjusted to make the two pin shafts 9 extruded into the corresponding positioning grooves 702 on the movable plate 7, so as to complete the installation and positioning.

[0040] In some embodiments, the upper end of the rack support plate 12 is a horizontal end face, the rotating shaft 11 is connected to the limiting plate 16, the limiting plate 16 is provided with a limiting bolt, and the lower end of the limiting bolt is located above the horizontal end face of the rack support plate 12; when the rotating shaft 11 rotates to a set limit position, the lower end of the limiting bolt abuts against the rack support plate 12.

[0041] When the rotating shaft 11 rotates, the limiting plate 16 also rotates, thereby driving the limiting bolt to move. When the rotating shaft 11 rotates to a pre-set limit position, the lower end of the limiting bolt is just moved above the horizontal end face of the rack support plate 12 and abuts against it, at this time, the limiting bolt prevents the rotating shaft 11 from continuing to rotate in this direction, thereby limiting the rotating range of the rotating shaft 11, and preventing the rotating shaft 11 from exceeding the safe range due to excessive rotation.

[0042] In some embodiments, the end of the rotating shaft 11 is connected to the driven sprocket 17, the rotary drive device 18 is connected to the driving sprocket, and the driven sprocket 17 and the driving sprocket are connected through the chain 19.

[0043] The chain transmission has good buffering and damping capacity, when the rotary drive device 18 starts, stops or the load changes, the chain 19 can absorb and buffer the impact force to a certain extent, reduce the vibration and impact on the rotating shaft 11 and other components, reduce the wear of the equipment, and prolong the service life of the equipment.

[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
