Description

Technical Field

[0001] This application relates to the field of calendar processing technology, and in particular to a punching device for calendar processing. Background Technology

[0002] In the production and processing of wall calendars, the punching process is a crucial step, providing the necessary structural foundation for subsequent operations such as binding.

[0003] This has exposed numerous problems, seriously affecting production efficiency and product quality, while also increasing the labor intensity of operators and the operating costs of enterprises.

[0004] Currently, existing calendar punching machines rely mainly on manual operation for calendar clamping. Specifically, operators need to manually place the calendar on the processing table and use adjusting clamps to fix it. In actual application, before each punching operation, operators need to spend a certain amount of time adjusting the position of the clamps and performing clamping operations, which prolongs the punching time of a single calendar and reduces production efficiency.

[0005] In addition, the process of punching holes in calendars generates debris that scatters everywhere, causing great inconvenience to subsequent cleaning.

[0006] To address the aforementioned issues, a punching device for calendar processing has been designed. Utility Model Content

[0007] This application provides a punching device for calendar processing to solve the problem that existing calendar punching machines rely mainly on manual operation for calendar clamping, which is cumbersome and inefficient.

[0008] Firstly, a punching device for calendar processing is provided, comprising:

[0009] A processing chamber is provided inside, with a cylinder, a punching head at the bottom of the piston rod of the cylinder, and an air source device connected to the cylinder.

[0017] One end of the housing is provided with a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to either end of the lead screw.

[0018] In some embodiments, the drive mechanism further includes two slide bars disposed opposite each other inside the processing chamber, the two slide bars being located on both sides of the housing, and sliders being slidably disposed on the outer walls of the slide bars, the sliders being connected to the bottom of the support plate.

[0019] In some embodiments, the recycling unit includes a recycling box located at the bottom of the processing chamber, a fan located on the recycling box, an air inlet pipe of the fan connected to the recycling box, and a filter screen installed on the air inlet pipe of the fan.

[0020] The recycling unit also includes a guide block located at the bottom of the processing chamber. One side of the guide block is inclined downwards, and the bottom of the processing chamber has multiple slag discharge ports located on the downwardly inclined side of the guide block.

[0021] In some embodiments, the adsorption pipeline includes a main pipeline connected to the recovery box, and the main pipeline is connected to multiple branch pipes, the other end of which is connected to a corresponding slag discharge port.

The drive mechanism can automatically drive the clamping unit and the calendar to move along the length of the processing chamber, eliminating the need for frequent manual adjustment of the calendar position and completing continuous punching operations. This greatly improves the efficiency of the punching operation and reduces the labor intensity of the operators.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] This application provides a punching device for calendar processing, which solves the problem that existing calendar punching machines rely mainly on manual operation for calendar clamping, which is cumbersome and inefficient.

[0035] Please see Figures 1-3 A punching device for calendar processing includes: a processing chamber 1, inside which a cylinder 2 is disposed, a punching head 21 is disposed at the bottom end of the piston rod of the cylinder 2, and an air source device 3 connected to the cylinder 2; a processing table 4 is arranged inside the processing chamber 1 below the punching head 21; characterized in that the processing table 4 is provided with a punching hole 41 below the punching head 21; a clamping unit 5 for clamping the calendar is disposed above the processing table 4; and a driving mechanism 6 is disposed inside the processing chamber 1, the driving mechanism 6 being used to drive the clamping unit 5 to move along the length of the processing chamber 1. The processing chamber 1 is equipped with an adsorption unit 7 at its bottom, which is used to collect waste generated after stamping. The clamping unit 5 includes two clamping plates 51 arranged opposite to each other on the processing table 4. The processing table 4 is equipped with two traveling mechanisms 52, which are connected to the clamping plates 51 and are used to drive the two clamping plates 51 to move closer to each other to fix the calendar. The adsorption unit 7 includes a recycling unit 71 at the bottom of the processing chamber 1 and an adsorption pipe 72 connected to the recycling unit 71. The other end of the adsorption pipe 72 is connected to the bottom of the processing chamber 1.

[0036] Place the calendar on the processing table 4 and start the traveling mechanism 52. The two traveling mechanisms 52 drive the corresponding clamping plates 51 to move closer to each other, and the calendar is clamped between the two clamping plates 51, thereby fixing the calendar and preventing it from shifting during the punching process, thus ensuring the accuracy of the punching position.

[0037] After the calendar is positioned, the air source device 3 is activated. The piston rod of the cylinder 2 extends downward under the action of the air source, driving the punch head 21 to move downward and punch holes in the calendar. The waste generated during the punching process will be scattered at the bottom of the processing chamber 1.

[0038] When it is necessary to punch holes in different positions of the calendar, the drive mechanism 6 is activated, and the processing table 4, the clamping unit 5 and the calendar move together along the length of the processing chamber 1, moving the position of the calendar to be punched to directly below the punching head 21. As the positions of the processing table 4 and the calendar are continuously adjusted, the punching head 21 repeatedly punches holes in the calendar.

[0039] At the same time, the recycling unit 71 is activated, and the waste material at the bottom of the processing chamber 1 is sucked in and recycled through the adsorption pipe 72.

[0040] The calendar can be accurately fixed on the processing table 4 by the clamping plate 51 and the traveling mechanism 52, preventing the calendar from shifting during the punching process, ensuring the accuracy of the punching position, and improving the quality of the punching. The driving mechanism 6 can automatically drive the clamping unit 5 and the calendar to move along the length of the processing chamber 1, eliminating the need for frequent manual adjustment of the calendar position and completing continuous punching operations, which greatly improves the efficiency of the punching operation and reduces the labor intensity of the operators.

[0041] By using the recycling unit 71 and the adsorption pipe 72 together, the waste generated after stamping can be collected in a timely and effective manner, preventing the waste from scattering everywhere, keeping the processing chamber 1 clean, and providing a good working environment for the operators.

[0042] like Figure 3 and Figure 4 As shown, the processing table 4 in this embodiment includes a support plate 43 and a surrounding plate 42 connected to each other. The surrounding plate 42 is U-shaped, with an opening at one end for feeding and discharging materials; two clamping plates 51 are located on both sides of the opening. The processing chamber 1 has an opening for feeding and discharging calendars. The stamping hole 41 is located at the end of the surrounding plate 42 away from the opening.

[0043] Before punching the calendar, the operator pushes the calendar to be punched onto the processing table 4 through the opening in the processing compartment 1 and the opening in the enclosure 42. Since the two clamps 51 are located on both sides of the opening in the enclosure 42, the calendar will not be obstructed when it enters the processing table 4, making it convenient to place the calendar.

[0044] After the calendar has been punched, the operator removes the punched calendar from the processing table 4 through the opening in the processing chamber 1 and the opening in the enclosure 42.

[0045] The U-shaped enclosure 42 provides space for the movement of the clamping plate 51 and also limits one side of the calendar. When the calendar is placed on the support plate 43, it is pushed to fit against the side of the enclosure 42, and then the clamping plate 41 fixes both sides of the calendar, further ensuring the stability of the calendar clamping.

[0046] like Figure 3 As shown, the clamp 51 described in this embodiment is L-shaped and is used to clamp the sides and top of the calendar.

[0047] The L-shaped clamp 51 clamps the calendar from both the side and top, which is more effective than a single-direction clamping method in preventing the calendar from shifting during the punching process. When the punch head 21 punches holes in the calendar, it generates a significant impact force. The multi-directional clamping action of the L-shaped clamp 51 ensures that the calendar remains in the correct position, guaranteeing the accuracy of the punching location and improving the quality of the punching.

[0048] like Figure 3 and Figure 4 As shown, in one embodiment, the traveling mechanism 52 includes an electric push rod 521 disposed on a surrounding plate 42, and two guide rods 522 inserted opposite each other on the surrounding plate 42. The two guide rods 522 are located on both sides of the electric push rod 521. The piston rod of the electric push rod 521 is connected to a corresponding clamping plate 51, and one end of the guide rod 522 is connected to a corresponding clamping plate 51. The surrounding plate 42 has through holes for mounting the guide rods 522 and the piston rods of the electric push rod 521.

[0049] When the calendar needs to be clamped, the electric push rod 521 is activated. The piston rod of the electric push rod 521 extends outward, and the extension of the piston rod will directly push the clamping plate 51 to move towards the other clamping plate 51.

[0050] When the clamping plate 51 is pushed by the piston rod of the electric push rod 521, the guide rod 522 will slide together with the clamping plate 51 in the through hole opened on the surrounding plate 42. The two guide rods 522 are located on both sides of the electric push rod 521, which can effectively prevent the clamping plate 51 from deflecting or shaking during the movement, and ensure that the clamping plate 51 always moves smoothly along the predetermined straight direction.

[0051] As the piston rod of the electric push rod 521 continues to extend, the two clamping plates 51 move closer together, eventually clamping and fixing the sides and top of the calendar. When the clamping force reaches a suitable level, the electric push rod 521 closes. At this time, the clamping plates 51 maintain a stable clamping state under the support and positioning of the guide rod 522, preparing for subsequent drilling operations.

[0052] like Figure 4 and Figure 5 As shown, in one embodiment, the drive mechanism 6 includes a housing 61 disposed at the bottom of the processing chamber 1. A lead screw 62 is rotatably disposed inside the housing 61. A moving block 63 is threadedly connected to the lead screw 62. Two transmission rods 64 are disposed opposite each other on the moving block 63. A through hole is provided on the housing 61, and the top end of the transmission rod 64 passes through the through hole and is connected to the bottom of the support plate 43. A drive motor and a reducer are disposed at one end of the housing 61. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to either end of the lead screw 62. A threaded hole adapted to the thread on the surface of the lead screw 62 is provided inside the moving block 63.

[0053] When it is necessary to drill holes in different positions of the calendar, the drive motor is started and starts to run. Its output shaft transmits the rotational power to the input shaft of the reducer. The reducer reduces the speed and increases the torque, converting the high-speed rotational power output by the drive motor into a low-speed, high-torque power suitable for driving the lead screw 62. Then, the output shaft of the reducer transmits the power to one end of the lead screw 62, causing the lead screw 62 to start rotating inside the housing 61.

[0054] Since the movable block 63 is threadedly connected to the lead screw 62, according to the principle of lead screw transmission, when the lead screw 62 rotates, the movable block 63 will move linearly along the axis of the lead screw 62. When the lead screw 62 rotates clockwise, the movable block 63 will move along the lead screw 62 to one end; when the lead screw 62 rotates counterclockwise, the movable block 63 will move along the lead screw 62 to the other end.

[0055] When the moving block 63 moves, it will drive the support plate 43 to move together through the transmission rod 64. The movement of the support plate 43 will drive the entire processing table 4, clamping unit 5 and calendar to move together along the length of the processing chamber 1, thereby moving the position of the calendar to be punched to directly below the punching head 21.

[0056] The lead screw drive has high transmission accuracy and can accurately control the moving distance of the moving block 63, thereby precisely controlling the moving position of the support plate 43 and the calendar.

[0057] By controlling the forward and reverse rotation and operating time of the drive motor, the automatic movement of the calendar can be easily achieved. It can be integrated with the equipment's control system to automatically adjust the calendar's position according to a preset program, automating the punching operation, improving production efficiency, and reducing the labor intensity and errors of manual operation.

[0058] like Figure 4 and Figure 5 As shown, the drive mechanism 6 further includes two slide rods 65 disposed opposite to each other inside the processing chamber 1. The two slide rods 65 are located on both sides of the housing 61. A slider 66 is slidably disposed on the outer wall of the slide rods 65. The slider 66 is connected to the bottom of the support plate 43.

[0059] When the transmission rod 64 pushes the support plate 43 to move, the support plate 43 will drive the slider 66 to slide on the slide rod 65.

[0060] Two slide rods 65 are located on both sides of the housing 61, providing support and guidance for the movement of the support plate 43. The slider 66 slides smoothly along the axial direction of the slide rods 65, working in conjunction with the lead screw transmission part to ensure that the support plate 43 always moves along the predetermined straight direction.

[0061] Meanwhile, the sliding rod 65 and the slider 66 can share some of the supporting force, making the force on the support plate 43 more even. During the movement, the sliding rod 65 and the slider 66 can also bear some of the force generated by inertia, preventing the support plate 43 from tilting or swaying due to uneven force, and further ensuring the stability of the calendar movement.

[0062] like Figure 6 and Figure 7 As shown, in one embodiment, the recycling unit 71 includes a recycling box 711 disposed at the bottom of the processing chamber 1, a fan 712 disposed on the recycling box 711, the air inlet pipe of the fan 712 being connected to the recycling box 711, and a filter screen disposed on the air inlet pipe of the fan 712; the recycling unit 71 also includes a guide block 713 disposed at the bottom of the processing chamber 1, one side of the guide block 713 being inclined downward, and a plurality of slag discharge ports 714 located on the downwardly inclined side of the guide block 713 being provided at the bottom of the processing chamber 1.

[0063] During the calendar punching process, waste residue is generated. Under the influence of gravity, this waste residue falls to the bottom of the processing chamber 1. Since the bottom of the processing chamber 1 is equipped with a guide block 713, and one side of the guide block 713 is inclined downwards, the waste residue will slide down along the inclined surface of the guide block 713 and enter the slag discharge port 714.

[0064] By starting the blower 712, it begins to operate. Its inlet pipe generates suction, drawing the waste residue discharged from the discharge port 714 into the recovery box 711 under the suction of the blower 712. Simultaneously, a filter screen is installed on the inlet pipe to prevent waste residue from entering the blower 712, thus preventing damage and ensuring its normal operation. After being drawn into the recovery box 711, the waste residue is temporarily stored there for subsequent centralized processing.

[0065] like Figure 2 and Figure 7 As shown, the adsorption pipe 72 includes a main pipe 721 connected to the recovery box 711, and a plurality of branch pipes 722 are connected to the main pipe 721. The other end of the branch pipe 722 is connected to the corresponding slag discharge port 714.

[0066] When the blower 712 is running, the suction it generates is transmitted to the main pipe 721 through the recovery box 711. Since the main pipe 721 is connected to multiple branch pipes 722, the suction will be further transmitted to each slag discharge port 714.

[0067] When the waste slag slides from the bottom of the processing chamber 1 through the guide block 713 to the slag discharge port 714, under the action of suction, the waste slag will smoothly pass through the slag discharge port 714 into the branch pipe 722, and then enter the main pipe 721 along the branch pipe 722, and finally be sucked into the recycling box 711.

[0068] like Figure 1 and Figure 2 As shown, it should be noted that a support frame is also installed at the bottom of the processing chamber 1, and a power distribution cabinet is also installed on the support frame. A controller is also installed on the processing chamber 1.

[0069] The support frame at the bottom of processing chamber 1 serves to support the entire processing chamber 1.

[0070] The distribution cabinet is mounted on a support frame and connected to an external power source. When the equipment starts up, electrical energy from the external power source first enters the distribution cabinet. Circuit breakers, contactors, relays, and other components inside the cabinet distribute and control the electrical energy. Based on the power requirements of various equipment components such as drive motors, fans, and control devices, the distribution cabinet accurately distributes electrical energy to the corresponding components to ensure their normal operation; this is existing technology and will not be elaborated upon further.

[0071] The control device is the core of the entire equipment's operation. Operators can send various commands to the equipment via buttons, touchscreens, or other input devices on the control device. When it is necessary to start the drive motor to move the calendar to a designated position, the operator presses the corresponding button on the control device. The control device receives this signal, converts it into an electrical signal, and sends it to the drive motor's control circuit, thereby controlling the drive motor's start, stop, forward rotation, and reverse rotation. Similarly, operators can also precisely control other components such as the fan and electric actuator through the control device to automate the calendar punching process. This is existing technology and will not be elaborated upon here.
