Description

Technical Field

[0001] This application relates to the field of punching technology, and in particular to a punching mechanism for printing tickets. Background Technology

[0002] In the printing industry, certain special-purpose printed tickets, such as individual tickets, labels, and receipts, often need to be punched in the middle or at specific locations after printing to meet functional requirements.

[0003] Reference Figure 1 A type of printed ticket includes ticket bodies 1 connected end-to-end, with punching holes 11 provided at the joints of adjacent ticket bodies 1. When processing the punching holes 11 of the printed ticket, the ticket is typically transported using a conveying device, and a punching mechanism is provided in the middle of the conveying device to process the punching holes 11. The punching mechanism is typically a cam-type punching mechanism or a hydraulic punching mechanism.

[0004] Regarding the aforementioned related technologies, the inventors have provided another punching mechanism for printing tickets, used for processing punching holes on printed tickets. Utility Model Content

[0005] To assist in processing the punching holes for printed tickets, this application provides a punching mechanism for printed tickets.

[0006] This application provides a punching mechanism for printing tickets, which adopts the following technical solution:

[0007] A punching mechanism for printing tickets includes a punching base, a punching die, a fixed bracket mounted on the punching base, a punching beam slidably mounted on the fixed bracket, and a drive assembly for driving the punching beam to move up and down; the fixed bracket is further provided with a reset structure that drives the punching beam to always have an upward reset; the punching die includes a lower punching die mounted on the punching base and an upper punching die mounted on the punching beam and correspondingly arranged to the lower punching die; the drive assembly includes a drive shaft, a drive cam mounted on the drive shaft, a drive wheel sleeve sleeved outside the drive cam, a first drive member hinged to the top of the fixed bracket, a first pressing rod hinged at one end to the first drive member and at the other end to the punching beam, and a drive connecting rod hinged at one end to the first drive member and at the other end to the drive wheel sleeve.

[0008] By adopting the above technical solution, when the printed document is located at the lower punching die, the drive shaft rotates, causing the drive cam to rotate. The drive cam drives the drive wheel sleeve to move downward, thereby driving the drive linkage to move downward. Since both the first pressing rod and the drive linkage are hinged to the first driving component, the first pressing rod moves downward and presses down the punching beam. The upper punching die moves downward, thus completing the punching of the printed document. After the punching of the printed document is completed, the reset structure drives the punching beam to reset upward. This application can assist in processing the punching holes of printed documents.

[0009] Optionally, the fixed bracket includes a first upright arranged vertically and located near the drive shaft, a second upright arranged vertically and located away from the drive shaft, and a fixing rod connecting the first upright and the second upright; the perforated beam has a first through hole for cooperating with the first upright and a first bushing cooperating with the first upright is provided at the first through hole; the perforated beam has a second through hole for cooperating with the second upright and a second bushing cooperating with the second upright is provided at the second through hole.

[0010] By adopting the above technical solution, the specific structure of the fixed bracket is disclosed. The first and second uprights provide guidance for the upward and downward sliding of the perforated beam, allowing both ends of the perforated beam to slide up and down along the first and second uprights. The first and second bushings improve the smoothness of the perforated beam during the sliding process.

[0011] Optionally, the drive assembly further includes a second drive member hinged to the top of the second upright, a second pressing rod hinged at one end to the second drive member and at the other end to the punch beam, and a synchronizing link connecting the second drive member and the first drive member so that the second drive member can rotate synchronously with the first drive member.

[0012] By adopting the above technical solution, the specific structure of the drive assembly is further disclosed. The arrangement of the second drive member, the second pressing rod, and the synchronous connecting rod enables the synchronous connecting rod to drive the second drive member to rotate synchronously when the drive connecting rod drives the first drive member to rotate, thereby driving the second pressing rod to move downward. This achieves the synchronous driving of the first pressing rod and the second pressing rod to move the punching beam downward, which helps to improve the stability of the punching beam when punching printed tickets.

[0013] Optionally, the first driving member is L-shaped and includes a first hinge portion, a first connecting portion connected to the first hinge portion, and a second connecting portion connected to the first hinge portion; the first pressing rod and the driving link are both hinged to the first connecting portion, the first pressing rod is located between the driving link and the first upright; the second connecting portion is located on the upper side of the first connecting portion.

[0014] By adopting the above technical solution, the specific structure of the first driving member is disclosed. The first hinge portion provides a rotation fulcrum for the first driving member. Both the first pressing rod and the driving link are hinged to the first connecting portion, so that when the driving link moves downward, it can drive the first pressing rod downward around the first hinge portion as the axis of rotation. The arrangement of the first pressing rod between the driving link and the first upright makes it easier for the driving link to drive the first pressing rod downward.

[0015] Optionally, the second drive member is L-shaped and includes a second hinge portion, a third connecting portion connected to the second hinge portion, and a fourth connecting portion connected to the second hinge portion; the second pressing rod is hinged to the third connecting portion and is located on the side facing the first upright; the second connecting portion is located on the upper side of the first connecting portion.

[0016] By adopting the above technical solution, the specific structure of the second driving member is disclosed. The second hinge portion provides a rotation fulcrum for the second moving member, enabling the synchronous connecting rod to drive the second driving member to rotate during lateral movement. Since the second pressing rod is hinged to the third connecting portion and located on the side facing the first upright, it can be driven to move downward.

[0017] Optionally, the reset structure includes a first reset spring and a second reset spring, wherein the first reset spring is sleeved on the first upright and located between the punched beam and the punched base; and the second reset spring is sleeved on the second upright and located between the punched beam and the punched base.

[0018] By adopting the above technical solution, the specific structure of the reset structure is disclosed. The arrangement of the first spring and the second spring enables the punching beam to be lifted upwards after punching, thereby resetting the punching beam.

[0019] Optionally, a limiting plate for pressing the printed document against the punching die is installed at the bottom of the stamping die.

[0020] By adopting the above technical solution, the setting of the limiting plate enables the upper punching die to press the printed document against the lower punching die first when the upper punching die moves downward, and then the upper punching die continues to move downward to complete the punching of the printed document, which helps to reduce the probability of the printed document shifting during punching.

[0021] Optionally, the limiting plate has upwardly bent portions at both ends.

[0022] By adopting the above technical solution, the setting of the bending part can reduce the probability of the printed ticket interfering with the limiting plate when passing through the punching die.

[0023] Optionally, the punching base has a limiting groove along its length and a limiting slider is slidably installed in the limiting groove. The top of the punching lower die is provided with a limiting through hole and a limiting bolt for threaded engagement with the limiting slider is installed at the limiting through hole.

[0024] By adopting the above technical solution, the cooperation of the limiting slide, the limiting slider and the punching lower die allows the punching lower die to be detachably installed on the punching base, which helps to improve the applicability of the punching mechanism for printing tickets.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A punching mechanism for printed tickets, wherein the driving cam and the driving wheel sleeve cooperate to enable the driving linkage to move downward, thereby driving the first driving member to rotate, thereby driving the first pressing rod to move downward and driving the punching beam to move downward, thereby completing the punching of printed tickets, which helps to assist in the punching process of printed tickets.

[0027] 2. By setting a first through hole and a second through hole at both ends of the punching beam, and setting a first bushing at the first through hole and a second bushing at the second through hole, the stability of the punching beam when sliding on the fixed bracket is ideal, which helps to improve the punching effect.

[0028] 3. By opening a limiting groove in the punching base, the limiting groove, the limiting slider, and the punching lower die can be detachably installed on the punching base, which helps to improve the applicability of the punching mechanism for printing tickets. Attached Figure Description

[0041] Reference Figure 2 and Figure 3The punching die 3 includes a lower punching die 31 mounted on the punching base 2 and an upper punching die 32 mounted on the bottom of the punching beam 5. In this embodiment, there are two lower punching dies 31, which are spaced apart along the length of the punching base 2. The top of the lower punching die 31 has a punching groove 311 for forming the punched hole 11.

[0042] Reference Figure 3 and Figure 4 To enable the punching die 31 to be detachably mounted on the punching base 2, the punching base 2 has a limiting groove 21 along its length and a limiting slider 22 is installed within the limiting groove 21. The punching die 31 has a limiting through hole 312 penetrating through its upper and lower surfaces. A limiting screw hole 313 is provided at the top of the limiting slider 22, and a limiting bolt 314 is installed at the limiting through hole 312, which is threaded into the limiting screw hole 313 of the limiting slider 22. In this embodiment, the cross-sections of the limiting groove 21 and the limiting slider 22 are both trapezoidal, and the widths of the limiting groove 21 and the limiting slider 22 gradually increase from top to bottom.

[0051] Combination Figures 1 to 8 The implementation principle of a punching mechanism for printed tickets according to an embodiment of this application is as follows: When the printed ticket is located in the lower punching die 31, the drive motor drives the drive shaft 61 to rotate, thereby driving the drive cam 62 to rotate. The drive cam 62 abuts against the drive surface 6311, thereby driving the drive wheel sleeve 63 to move downward. The drive linkage 67 drives the first drive member 65 to rotate, so that the first pressing rod 66 moves downward. At the same time, the second connecting part 653 drives the synchronous connecting rod 610 to move, thereby driving the second pressing rod 69 to move downward. So that the first pressing rod 66 and the second pressing rod 69 synchronously move the punching beam 5 downward, thereby driving the upper punching die 32 to move downward to complete the punching of the printed ticket. After the punching is completed, the first return spring 71 and the second return spring 72 drive the punching beam 5 to return upward.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
