Description

Technical Field

[0001] The utility model relates to the technical field of binding machines, in particular to an automatic binding device for a printing machine. Background Art

[0002] A binder is an office device used to fasten materials such as paper, plastic, and leather together by mechanically punching holes in the paper and passing binding material through the holes to bind the paper into volumes.

[0003] The binding machines are divided into small binding machines and large binding machines. Small binding machines are suitable for single-person use, while large binding machines are used for industrial or professional binding. When punching holes in paper, the binding machine will use a hollow drill bit to punch holes at the designated positions of the document so that the binding wire or binding nails can pass through. The waste chips generated by the holes will be automatically discharged through the chip removal system in the binding machine. Then prepare for binding. Through the capping mechanism or other binding mechanism on the binding machine, the prepared binding wire or binding nails will be passed through the holes on the document and fixed on the other side to achieve the binding of the document.

[0004] However, the drilling group and the binding group of the large binding machine are not arranged together. There is a conveyor belt between the two for transmission. A broom tassel is arranged above the conveyor belt between the drilling group and the binding group. The purpose is to clean the debris remaining on the surface of the paper after drilling. However, the broom tassel needs to be removed from the structure for fixing the broom tassel after cleaning the debris for a period of time, and the debris attached to the inside of the broom tassel needs to be cleaned. If the broom tassel is not cleaned, there will be too much debris remaining on the surface of the paper, which affects the subsequent binding. However, when the broom tassel is removed from the structure for fixing the broom tassel, the conveyor belt needs to be stopped and the broom tassel needs to be replaced. However, this method will cause the paper to accumulate in the drilling group and cannot enter the binding group. The only way to prevent accumulation is to close the drilling group and the binding group at the same time. This method may greatly reduce the processing efficiency of paper binding and affect the overall production speed of the finished product. Therefore, an automatic binding device for a printing machine is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an automatic binding device for a printing machine.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic binding device for a printing machine, including a binding machine, a connecting table is arranged on the right end face of the binding machine, a conveyor belt is arranged on the top of the connecting table, a fixing rod is fixedly connected to the top of the front and rear end faces of the right side of the connecting table, a fixing plate is fixedly connected to the end of the fixing rod away from the connecting table, a first motor is fixedly connected to the right end face of the fixing plate, a limiting slide rail is fixedly connected to the left end face of the fixing plate, a convex block is slidably connected to the inner side of the limiting slide rail, a base is fixedly connected to the left end face of the convex block, an insert plate is slidably connected to the upper and lower sides of the base, and a broom tassel is fixedly connected to the outer end face of the insert plate.

[0007] As a further description of the above technical solution: the output end of the first motor is fixedly connected to the middle of the right end face of the base, the right end face of the base contacts the left end face of the fixed plate, and the right end face of the convex block contacts the right side inside the fixed plate. The broom tassels located above the base can be transferred to the bottom and the surface of the paper can be cleaned without stopping the conveyor belt. When the broom tassels need to be cleaned and transferred to the top of the base, the operator can take out the plug plate together with the broom tassels from the base and clean them, thereby improving the efficiency of the paper entering the binding machine for binding to a certain extent.

[0008] As a further description of the above technical solution: the first motor is a stepper motor, and the rotation cycle of the first motor each time it is started is one hundred and eighty degrees. A circular hole is opened in the middle of the fixed plate, and the circular hole in the middle of the fixed plate is inserted by the output shaft of the first motor and directly connected to the left end face of the base. The first motor can be set to drive the base to rotate one hundred and eighty degrees each time it is started, which is fast and prevents the broom tassels under the base from being unable to clean the paper above the conveyor belt due to angle problems.

[0009] As a further description of the above technical solution: the number of the plug plates and the broom tassels are both two, and the plug plates and the broom tassels are distributed on the upper and lower sides of the base. Slide grooves are provided on the upper and lower sides of the base, and the cross-sectional shapes of the slide grooves on the upper and lower sides of the base are the same as the cross-sectional shapes of the plug plates. The broom tassels can be quickly removed from the inner side of the base, which is convenient for replacement while allowing the broom tassels to seamlessly connect and continue to clean paper debris.

[0010] As a further description of the above technical solution: the shape of the limiting slide rail is one-third of a circle, and the inner cross-sectional shape of the limiting slide rail is the same as the cross-sectional shape of the convex block, so that the convex block can bear part of the weight of the base and the broom tassels, preventing the output shaft of the first motor from bearing the weight of the base and the broom tassels for a long time and bending.

[0011] As a further description of the above technical solution: an L-shaped plate is fixedly connected in the middle of the front and rear end surfaces of the connecting platform, and the end of the L-shaped plate away from the connecting platform is fixedly connected to a hollow shell, and the left end surface of the hollow shell is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to a bidirectional threaded rod, and the end of the bidirectional threaded rod away from the second motor is rotatably connected to the middle of the right side of the hollow shell, and a moving block is spirally connected to the outer side of the bidirectional threaded rod, and the end of the moving block close to the conveyor belt is rotatably connected to a connecting rod, and the outer surface of the connecting rod is slidably connected to an end surface of the hollow shell close to the conveyor belt, and the end of the connecting rod away from the moving block is rotatably connected to an extrusion plate, and the end surface of the extrusion plate away from the connecting rod is fixedly connected to a rubber sheet, and the end surface of the rubber sheet away from the extrusion plate contacts with the front and rear end surfaces of the base, which can prevent the weight of the base together with the plug plate and the broom tassel from being always borne by the output shaft and the convex block of the first motor, thereby greatly reducing the force exerted on the output shaft and the convex block of the first motor.

[0012] As a further description of the above technical solution: a through groove is opened in the middle of one end face of the hollow shell close to the conveyor belt, and the width of the through groove of the hollow shell is the same as the cross-sectional diameter of the connecting rod, the width of the rubber sheet is the same as the width of the base, and the thickness of the rubber sheet is three millimeters. The rubber sheet can increase the friction between the clamping plate and the base, and at the same time prevent the corners of the clamping plate from squeezing the edge of the base with too much force, causing indentations and deformation on the edge of the base.

[0013] The utility model has the following beneficial effects:

[0014] 1. The automatic binding device for a printing machine designed by the utility model can, through design coordination, enable the device to replace the broom tassels that enter the binding machine in advance and clean the surface of the paper, and can transfer the broom tassels located above the base to the bottom and clean the surface of the paper without stopping the conveyor belt. The operator can take out the plug plate together with the broom tassels from the base and clean them when the broom tassels need to be cleaned and transferred to the top of the base, thereby improving the efficiency of the paper entering the binding machine for binding to a certain extent and reducing the number of times the binding machine and the conveyor belt are stopped due to cleaning the broom tassels.

[0015] 2. The automatic binding device for a printing press designed by the utility model is designed so that after the base rotates 180 degrees and stops, the second motor on the front side of the hollow shell starts and moves the extrusion plate to the front and rear sides of the base, clamping and fixing the left and right sides of the base, thereby preventing the weight of the base together with the plug plate and the broom tassels from always being borne by the output shaft and the convex block of the first motor, greatly reducing the force on the output shaft and the convex block of the first motor, and increasing the overall service life of the output shaft and the convex block of the first motor.

A circular hole is opened in the middle of the fixed plate 5, and the circular hole in the middle of the fixed plate 5 is inserted by the output shaft of the first motor 6 and directly connected to the left end face of the base 7. The first motor 6 can be set to drive the base 7 to rotate one hundred and eighty degrees each time it is started, which is fast and prevents the broom tassel 8 under the base 7 from being unable to clean the paper above the conveyor belt 3 due to angle problems.

The end face of the rubber sheet 16 away from the extrusion plate 13 is in contact with the front and rear end faces of the base 7, which can prevent the weight of the base 7 together with the plug plate 17 and the broom tassel 8 from being always borne by the output shaft and the convex block 18 of the first motor 6, thereby greatly reducing the force on the output shaft and the convex block 18 of the first motor 6.

[0027] As a further implementation scheme of the above technical scheme: a through groove is opened in the middle of one end face of the hollow shell 10 close to the conveyor belt 3, and the width of the through groove of the hollow shell 10 is the same as the cross-sectional diameter of the connecting rod 12, the width of the rubber sheet 16 is the same as the width of the base 7, and the thickness of the rubber sheet 16 is three millimeters. The rubber sheet 16 can increase the friction between the clamping plate and the base 7, and at the same time prevent the corners of the clamping plate from squeezing the edge of the base 7 with too much force, thereby causing indentations and deformation on the edge of the base 7.

[0028] Working principle:

[0029] When using the utility model, insert the plug plate 17 together with the broom tassel 8 into the grooves on the upper and lower sides of the base 7, the top of the broom tassel 8 located above the base 7 is located at the top, and the plug plate 17 at the bottom of the broom tassel 8 is inserted into the groove above the base 7, and the bottom of the broom tassel 8 located below the base 7 is located at the bottom, and the plug plate 17 at the top of the broom tassel 8 is inserted into the groove above the base 7. At this time, the binding machine 1 and the conveyor belt 3 can be opened, and after the punching of the paper to be bound is completed, it is transported to the binding machine 1 through the conveyor belt 3 on the top of the connecting table 2 for binding operation. When the paper moves through the conveyor belt 3, the broom tassel 8 below the base 7 cleans the punching place of the paper to prevent the binding machine 1 from binding the punching place of the paper When the broom tassel 8 is used, the paper scraps are caught in the gap between the papers along with the binding, and after the broom tassel 8 has cleaned the paper surface for a certain period of time, the operator needs to manually replace the broom tassel 8. At this time, the second motor 11 on the left end face of the hollow shell 10 is first opened, and the second motor 11 drives the bidirectional threaded rod 14 at the output end to rotate counterclockwise, and the moving block 15 on the outer side of the bidirectional threaded rod 14 is affected by the counterclockwise rotation of the bidirectional threaded rod 14 and moves toward the top of the left and right sides of the inside of the hollow shell 10, and the connecting rod 12 on the inner end face of the moving block 15 drives the squeezing plate 13 and the rubber sheet 16 at the top thereof to loosen the front and rear surfaces of the base 7, and then the first motor 6 located on the upper right side of the connecting platform 2 is opened. Due to the setting, the first motor 6 can only rotate one hundred times at a time. The first motor 6 rotates 180 degrees, and the first motor 6 drives the base 7 to rotate 180 degrees as a whole through the output shaft at the output end. The convex block 18 on the front side of the base 7 rotates and limits inside the limiting slide rail 19 on the left end face of the fixed plate 5. The plug plate 17 and the broom tassel 8 on the inner side of the base 7 rotate together with the base 7. At this time, the broom tassel 8 originally located above the base 7 does not clean the paper debris. After the base 7 rotates 180 degrees, the broom tassel 8 originally located above the base 7 is transferred to the bottom of the base 7 and contacts the paper and cleans the debris. The broom tassel 8 that originally cleaned the debris below the base 7 is moved to the top of the base 7 through rotation. At this time, the operator only needs to pull the plug plate 17 above the base 7 out of the slide groove to the left and replace it with a new one. The plug plate 17 and the broom tassel 8 are sufficient. When the operator replaces the broom tassel 8, the second motor 11 is started, and the second motor 11 is reversed to drive the bidirectional threaded rod 14 to rotate clockwise. The moving block 15 on the outside of the bidirectional threaded rod 14 moves toward the middle of the hollow shell 10, and the connecting rod 12 on the front side of the moving block 15 drives the extrusion plate 13 and the rubber sheet 16 to move toward the front and rear surfaces of the base 7 until the rubber sheet 16 contacts the front and rear surfaces of the base 7 and then stops the second motor 11. At this time, the broom tassel 8 under the base 7 seamlessly cleans the debris of the paper above the conveyor belt 3, thereby improving the efficiency of the paper entering the binding machine 1 for binding to a certain extent and reducing the number of times the binding machine 1 and the conveyor belt 3 are stopped due to cleaning the broom tassel 8.
