Description

Technical Field

[0001] The invention relates to the technical field of die-cutting machines, and in particular to an anti-top-collision mechanism for aligning paper at a delivery side of a die-cutting machine. Background Art

[0002] The die-cutting machine needs to be equipped with left and right side paper aligning devices in the paper collection section to collect the paper neatly. Generally, after the paper pile is collected, the paper collection pile will drop and move out of the machine. However, during the operation of the machine, the paper collection pile will rise again and enter the left and right side paper aligning area of ​​the paper collection pile. If one side of the left or right side paper collection pile exceeds the side paper aligning area of ​​the left and right side paper collection pile at this time, the paper pile will hit the side paper aligning device of the machine, causing damage to the mechanism. At present, the main method to prevent the side paper aligning device of the die-cutting machine from hitting the top is that the operator needs to pay attention and observe when the paper collection pile rises, which is a waste of manpower and time costs. Figure 1 As shown, when the paper pile 10 of the collected paper exceeds the paper aligning area of ​​the paper aligning device on the collecting side, if the paper pile continues to rise, it will hit the paper collecting side clapper 1 of the left and right paper aligning devices on the collecting side, causing damage to the paper aligning devices on the collecting side. In this case, it is necessary to stop the paper pile 10 from rising, readjust the position of the paper pile 10, and then rise again.

[0003] The side clappers of the delivery side paper aligning device on some die-cutting machines are fixed on left and right after their left and right positions are adjusted according to the size of the delivery paper. In addition, some side clappers on the delivery side have a 20-25mm paper-beating movement on left and right after their left and right positions are adjusted according to the size of the delivery paper. The side clappers of these two types of delivery side paper aligning devices may be hit by the paper pile, causing damage to the delivery side paper aligning device, and then causing the teeth row of the die-cutting machine to be hit, causing greater damage. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide an anti-top-impact mechanism for aligning the paper on the delivery side of a die-cutting machine, which prevents the delivery paper pile from rising and protects the delivery side aligning device.

[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 2 to Figure 4 As shown, the present invention relates to an anti-top-collision mechanism for aligning paper on the delivery side of a die-cutting machine, comprising an L-shaped delivery side clapper 1, a side clapper sliding assembly 2, an adjustment seat 3, a swinging side clapper 8, a rotating shaft 4, a trigger switch 7 and an alarm module.

[0028] The L-shaped paper collecting side clapper 1 is installed on the side clapper sliding assembly 2. The side clapper sliding assembly 2 is responsible for the clapping action of 20-25mm left and right of the paper collecting, or the paper collecting side clapper does not clasp the paper. The side clapper sliding assembly 2 is installed on the adjustment seat 3, and the adjustment seat 3 is responsible for adjusting the left and right position of the L-shaped paper collecting side clapper 1 according to the size of the paper collected. The swing side clapper 8 can swing up and down around the rotating shaft 4, and the rotating shaft 4 is fixed below the paper collecting side clapper 1. The paper clapping plane of the swing side clapper 8 is in the same plane as the paper clapping plane of the L-shaped paper collecting side clapper 1. The swing range of the swing side clapper 8 is limited by the pin 9 fixed on the swing side clapper 8 and the waist groove hole 5 on the L-shaped paper collecting side clapper 1. The lowest position of the swing side clapper 8 is lower than the lowest position of the L-shaped paper collecting side clapper 1. The trigger switch 7 is installed on the trigger switch bracket 6. The installation position of the trigger switch 7 can be adjusted. The trigger switch bracket 6 is fixed to the edge of the adjustment seat 3. The trigger switch 7 is connected to an alarm module (not shown in the figure) and is used to trigger the alarm module to sound an alarm. The alarm module is preferably an audible and visual alarm.

[0029] When the paper pile exceeds the paper aligning area of ​​the paper aligning device on the paper collecting side and rises, the paper pile first touches the swinging side clapper 8, and the swinging side clapper 8 swings upward around the rotating shaft 4. When the paper pile is about to approach the bottom position of the L-shaped paper collecting side clapper 1, the pin 9 fixed on the swinging side clapper 8 swings upward with the swinging side clapper 8. The pin 9 triggers the trigger switch 7 to generate an alarm signal, and the paper pile stops rising to prevent it from hitting the paper collecting side aligning device.

[0030] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
