Description

Technical Field

[0001] This utility model belongs to the field of calendar production technology, and in particular relates to a hole-opening device for processing calendar paper. Background Technology

[0002] A calendar is a tool used to record and track time, typically dividing and displaying time in units of days, weeks, months, or years. It is a type of everyday publication used to record dates and other relevant information. The production and processing of a calendar involves punching holes in multiple pages and binding them together to form a complete calendar. A punching device is needed for this process.

[0003] Based on research and practical experience in calendar processing and production, it was found that existing perforation devices on the market still have some shortcomings in practical applications: they are not convenient for simultaneously perforating multiple calendars of different sizes, have poor applicability, and cannot meet different production needs. Furthermore, after perforation, paper residue remains in the syringe, making quick and efficient cleaning difficult and affecting subsequent perforation. Therefore, there is an urgent need to improve existing perforation devices for calendar paper processing and provide a more versatile perforation device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a calendar paper processing opening device that is reasonably designed, simple in structure, suitable for different sizes of calendar openings, and facilitates the cleaning of residual paper inside the syringe, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A punching device for processing calendar paper includes a counterweight base plate. A servo motor is fixedly installed on the left rear outer wall of the counterweight base plate. A bidirectional lead screw is installed in the internal bearing of the rear end of the counterweight base plate. The left end of the bidirectional lead screw is fixedly connected to the output end of the servo motor. Movable frames are threaded onto the outer sides of both ends of the bidirectional lead screw. Vertical rods are fixedly connected to the top front ends of the two movable frames. Limit plates are fixed on the sides of the bottoms of the two vertical rods that are close to each other. A spacing adjustment component is installed between the tops of the two vertical rods. Electric push rods are fixedly installed on the sides of the tops of the two vertical rods that are opposite to each other. A crossbar is fixedly connected to the telescopic end of the electric push rod. Multiple punching components are installed at equal intervals on the outer side of the crossbar.

[0007] In a preferred embodiment, the rear end of the counterweight base plate is provided with guide grooves symmetrically arranged on the left and right sides, the bottom ends of the two movable frames are respectively engaged and slidably located in the two guide grooves, and the upper end of the vertical rod is provided with a through groove.

[0008] In a preferred embodiment, the spacing adjustment assembly includes a limiting rod, a movable block, a scissor-type telescopic rod mechanism, and a limiting sleeve. The two limiting rods are respectively fixedly installed in through slots opened inside the two vertical rods. Movable blocks are slidably sleeved on the outer sides of the two limiting rods. A scissor-type telescopic rod mechanism is installed between the two movable blocks. Multiple sets of limiting sleeves are installed on the scissor-type telescopic rod mechanism at equal intervals along the horizontal direction. Each set of limiting sleeves has two sleeves arranged symmetrically about the scissor-type telescopic rod mechanism.

[0009] In a preferred embodiment, the upper left and right ends of the scissor-type telescopic rod mechanism are respectively hinged to the two vertical rods, and the lower left and right ends of the scissor-type telescopic rod mechanism are respectively hinged to the two movable blocks. The multiple sets of limiting sleeves and the multiple sets of opening components are arranged in a one-to-one correspondence.

[0010] In a preferred embodiment, the hole-opening assembly includes a drill rod, a top block, a groove, an ejector rod, and a connecting rod. The top block is fixedly connected to the top of the drill rod, and the top block is slidably sleeved on the outside of the crossbar. A groove is formed on the outer wall of the bottom front end of the drill rod, and an ejector rod is slidably connected to the inner side of the bottom end of the drill rod. The connecting rod is L-shaped, with one end fixedly connected to a limiting sleeve and the other end passing through the groove and fixedly connected to the top of the ejector rod.

[0011] In a preferred embodiment, the drill rod is slidably connected to the limiting sleeve, and a cutter head is fixedly connected to the bottom end of the drill rod. The cutter head has an annular structure and its thickness decreases from top to bottom.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In the solution of this utility model:

[0014] The calendar papers to be perforated are neatly stacked and placed above the center of the counterweight base plate. The servo motor is started to control the bidirectional lead screw to rotate, controlling the two movable frames, vertical rods and limiting plates to move closer to each other, thus centering the paper. When the two vertical rods move closer, the movable block can rise along the limiting rod, and the left and right ends of the scissor-type telescopic rod mechanism retract towards the center position at the same time, thereby adjusting the spacing between multiple sets of perforation components. This device can adaptively adjust the perforation spacing according to the size of the calendar paper produced. The device has a wider range of applications and is more practical, and can adapt to various processing needs.

[0015] The electric push rod can control the crossbar to drive multiple top blocks and multiple drill rods to move vertically downwards along the limiting sleeve in sync. The multiple drill rods and their bottom ring cutters make it easy to make multiple holes in the calendar paper at the same time. The hole making speed is fast. When the electric push rod controls the crossbar and drill rods to rise and reset, the ejector rod can automatically push out the residual paper inside the drill rod, which is convenient for quick and efficient cleaning of the residual paper.

[0023] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0024] like Figure 1-4 As shown, the present invention relates to a hole-opening device for calendar paper processing, comprising a counterweight base plate 1, a servo motor 2 fixedly installed on the left rear outer wall of the counterweight base plate 1, a bidirectional lead screw 3 installed in the bearing inside the rear end of the counterweight base plate 1, the left end of the bidirectional lead screw 3 being fixedly connected to the output end of the servo motor 2, movable frames 5 being threadedly fitted on the outer sides of both the left and right ends of the bidirectional lead screw 3, vertical rods 6 being fixedly connected to the top front ends of the two movable frames 5, limit plates 11 being fixedly fixed on the sides of the bottom of the two vertical rods 6 that are close to each other, a spacing adjustment component 7 being installed between the tops of the two vertical rods 6, and electric push rods 8 being fixedly installed on the sides of the tops of the two vertical rods 6 that are opposite to each other, a crossbar 10 being fixedly connected to the telescopic end of the electric push rod 8, and multiple sets of hole-opening components 9 being installed at equal intervals on the outer side of the crossbar 10.

[0025] Based on the above structure, the rear end of the counterweight base plate 1 is provided with guide grooves 4 symmetrically arranged on the left and right sides. The bottom ends of the two movable frames 5 are respectively engaged and slidably located in the two guide grooves 4, and the upper end of the vertical rod 6 is provided with a through groove.

[0026] In this embodiment, the opening of the guide groove 4 can improve the stability of the sliding adjustment of the movable frame 5 and the vertical rod 6.

[0027] Based on the above structure, the spacing adjustment component 7 includes a limiting rod 71, a movable block 72, a scissor-type telescopic rod mechanism 73, and a limiting sleeve 74. The two limiting rods 71 ​​are respectively fixedly installed in the through slots opened inside the two vertical rods 6. The movable block 72 is slidably sleeved on the outer side of each of the two limiting rods 71. The scissor-type telescopic rod mechanism 73 is installed between the two movable blocks 72. Multiple sets of limiting sleeves 74 are installed on the scissor-type telescopic rod mechanism 73 at equal intervals along the horizontal direction. Each set of limiting sleeves 74 has two symmetrically arranged about the scissor-type telescopic rod mechanism 73.

[0028] Based on the above structure, the upper left and right ends of the scissor telescopic rod mechanism 73 are respectively hinged to two vertical rods 6, and the lower left and right ends of the scissor telescopic rod mechanism 73 are respectively hinged to two movable blocks 72. Multiple sets of limiting sleeves 74 are set in a one-to-one correspondence with multiple sets of opening components 9.

[0029] In this embodiment, when the two vertical rods 6 are controlled to move in opposite directions, the scissor-type telescopic rod mechanism 73 is used to facilitate the adjustment of the spacing between multiple sets of limiting sleeves 74 and multiple sets of opening components 9. The opening spacing can be adaptively adjusted according to the size of the calendar paper produced, and the device has a wider range of applications.

[0030] Based on the above structure, the hole-opening assembly 9 includes a drill rod 91, a top block 92, a sliding groove 93, an ejector rod 94, and a connecting rod 95. The top block 92 is fixedly connected to the top of the drill rod 91, and the top block 92 is slidably sleeved on the outside of the crossbar 10. A sliding groove 93 is opened on the outer wall of the bottom front end of the drill rod 91. An ejector rod 94 is slidably connected to the inner side of the bottom end of the drill rod 91. The connecting rod 95 is "L" shaped, with one end fixedly connected to the limiting sleeve 74, and the other end passing through the sliding groove 93 and fixedly connected to the top of the ejector rod 94.

[0031] Based on the above structure, the drill rod 91 is slidably connected to the limiting sleeve 74, and the bottom end of the drill rod 91 is fixedly connected to the cutter head 96. The cutter head 96 has a ring structure and its thickness decreases from top to bottom.

[0032] In this embodiment, when the crossbar 10 and drill rod 91 are raised and reset by the electric push rod 8, the residual paper inside the drill rod 91 can be automatically pushed out by the ejector rod 94, which facilitates quick and efficient cleaning of the residual paper and avoids affecting subsequent drilling.

[0033] The working principle of this utility model is as follows:

[0034] In use, first, the calendar paper to be perforated is neatly stacked and placed above the center of the counterweight base plate 1. Then, the servo motor 2 is started to control the bidirectional lead screw 3 to rotate, which allows the two movable frames 5 to drive the two vertical rods 6 and the corresponding limiting plates 11 to move along the guide groove 4 and approach each other, thus centering the paper. Moreover, when the two vertical rods 6 are brought closer together, the movable block 72 can rise along the limiting rod 71, and the left and right ends of the scissor telescopic rod mechanism 73 can retract towards the center position at the same time, thereby adjusting the spacing of multiple sets of limiting sleeves 74 and multiple sets of perforation components 9. This device can adaptively adjust the perforation spacing according to the size of the calendar paper produced. The device has a wider range of applications and is more practical, and can adapt to various processing needs.

[0035] After the spacing of multiple sets of hole-opening components 9 is adjusted, the two electric push rods 8 on the left and right can be opened to retract. The control bar 10 can drive multiple top blocks 92 and multiple drill rods 91 to move vertically downward along the limiting sleeve 74 in sync. By using multiple drill rods 91 and their bottom ring cutter heads 96, it is convenient to open multiple holes in the calendar paper at the same time. The hole-opening speed is fast and the efficiency is high.

[0036] When drilling, paper residue may remain inside the drill rod 91. When the electric push rod 8 extends to control the crossbar 10 and the drill rod 91 to rise and reset, the ejector rod 94 can automatically eject the residual paper inside the drill rod 91, facilitating quick and efficient cleaning of the residual paper and avoiding affecting subsequent drilling operations.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
