Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment and discloses a material retracting and unreeling shaft top-resting execution device. Background Art

[0002] In the printing industry, especially in large-scale printing equipment, the design and execution of the reel are crucial to the printing quality and equipment performance. In traditional printing equipment, air shafts are often used to support and fix the printing paper rolls for easy reeling and unreeling.

[0003] In the printing industry, the pneumatic shaft is used in conjunction with the paper roll rewinding and unwinding method as the loading and unloading mechanism of the printing equipment. The material shaft is driven by a frequency conversion motor through a synchronous belt or a gear at one end. The material roll is replaced manually. In the actual operation process, there are problems such as high labor intensity, poor roll alignment accuracy, easy collision between the pneumatic shaft and the transmission parts, and affected transmission accuracy. At the same time, the short pneumatic shaft structure of the rewinding device, more manpower required when loading the paper roll, time-consuming and labor-intensive unloading, and a small part of the two ends of the paper roll contacting the expansion shaft support with the middle part being empty also affect the working efficiency of the printing machine and the quality of printed products. The above situation has caused waste of labor and materials for enterprises using printing equipment, affected printing production efficiency, and brought unnecessary economic burden to enterprises.

[0004] Our company has proposed a top clamping mechanism for an air shaft, and the Chinese patent (application number: CN202120519100.0) discloses a top clamping mechanism for an air shaft, including a top clamping part and an adjustment part, and the top clamping part and the adjustment part are respectively clamped at the two ends of the expansion shaft. The top clamping part includes a top clamping sleeve seat and a top clamping mechanism installed inside the top clamping sleeve seat, and the top clamping mechanism also includes a telescopic mechanism for pushing the top clamping sleeve shaft to move axially; the adjustment part includes an adjustment sleeve seat and an adjustment sleeve shaft installed in the adjustment sleeve seat; and a matching mechanism for matching with the end of the expansion shaft is provided at the front end of the adjustment sleeve shaft. In the utility model, the adjustment part serves as the end limit end of the expansion shaft. After the expansion shaft is placed in the pre-installation position, the expansion shaft is pushed to move toward the adjustment part through the top clamping part, and finally the two ends of the expansion shaft are clamped between the top clamping sleeve shaft and the adjustment sleeve shaft, and the top clamping sleeve shaft, the expansion shaft and the adjustment sleeve shaft are locked in the axial direction under the action of the locking mechanism and the matching mechanism, thereby completing the installation of the expansion shaft.

[0028] Specifically, the support frames 1 on both sides are coaxially arranged, and the support frame 1 on one side is used to set up a transmission structure, which drives the inflatable shaft 2 to rotate through a motor and a transmission mechanism. The inflatable shaft 2 is used for winding and unwinding. The top clamping mechanism is used to fix the inflatable shaft 2 between the two support frames 1 so that the material can be wound and unwound. The deviation adjustment mechanism is arranged on the other side of the inflatable shaft 2, which is used to adjust the inflatable shaft 2 to the left and right, to ensure that the printed paper roll will not deviate during the winding and unwinding operation, thereby improving the quality of winding and unwinding.

When the first cone top 5 fits with the conical portion 3, the external gear 4 and the internal gear 6 are meshed.

[0030] During use, after the inflatable shaft 2 is placed between the support frames 1, the conical portion 3 on the inflatable shaft 2 is coaxially arranged with the first conical top 5, and the top clamping mechanism is started to make the conical portion 3 fit with the first conical top 5 until it can no longer be pushed in. At this time, the internal gear 6 and the external gear 4 are meshed, and the internal gear 6 clamps the inflatable shaft 2 from the outside of the inflatable shaft 2, and the other side of the inflatable shaft 2 is supported by the deviation adjustment mechanism. At this time, the top clamping of the inflatable shaft 2 is completed.

[0031] In a preferred embodiment, the clamping mechanism also includes a first clamping shaft 7 connected to the first cone top 5, and a clamping cylinder 8. The first clamping shaft 7 is coaxially arranged with the pneumatic shaft 2 through a first supporting sleeve 9, and the side of the first clamping shaft 7 away from the first cone top 5 is connected to the output end of the clamping cylinder 8.

[0032] Specifically, the first tightening shaft 7 is slidably set in the first supporting sleeve 9, one end of which is connected to the output end of the tightening cylinder 8, and the other end is connected to the first cone top 5. Under the action of the tightening cylinder 8, the first tightening shaft 7 drives the first cone top 5 to approach or move away from the inflatable shaft 2, thereby realizing the top clamping of the inflatable shaft 2.

[0033] Furthermore, the outer side of the first tightening shaft 7 is meshed with the spline transmission sleeve 10 through internal and external splines, one side of the first support sleeve 9 is connected to the spline transmission sleeve 10, the first support sleeve 9 is connected to the transmission mechanism to drive the pneumatic shaft 2 to rotate, the outer spline of the first tightening shaft 7 is meshed and connected with the spline transmission sleeve 10, the spline transmission sleeve 10 is coaxially connected to the first support sleeve 9, and the first support sleeve 9 is connected to the transmission mechanism to drive the pneumatic shaft 2 to rotate.

[0035] A mounting seat 11 is disposed outside the first tightening shaft 7 . The mounting seat 11 is connected to the support frame 1 , and the tightening cylinder 8 is disposed on the mounting seat 11 .

[0036] The mounting seat 11 is used to fix the jacking cylinder 8. Meanwhile, in the present embodiment, the mounting seat 11 surrounds the first jacking shaft 7 and the transmission structure to form a protective cover to protect the internal structure and improve the safety of the device.

A slide seat 16 is provided on the outer side of the second tightening shaft 14, and the second support sleeve 15 is rotatably arranged in the slide seat 16.

[0038] Specifically, the second tightening shaft 14 is slidably set in the second supporting sleeve 15, one end of which is connected to the second cone top 13, and the other end is connected to the adjusting screw group.
