Description

Technical Field

[0001] This utility model relates to the field of thermal paper processing technology, specifically a punching device for thermal paper processing. Background Technology

[0002] Thermal paper is a special coated paper that develops color when heated, enabling the printing of text or images without the need for traditional inks. Thermal paper is widely used in receipts, invoices, labels, and other applications. After punching holes, it can be directly inserted into binders or booklets for archiving, preventing documents from being scattered or lost.

[0003] Utility model CN222450628U discloses a punching device for processing thermal paper, including a worktable, a column fixed on the worktable, a first crossbar and a second crossbar fixed on the column, a first roller rotatably mounted on the first crossbar, a second roller rotatably mounted on the second crossbar, a plurality of circular cutters on the side wall of the first roller, a plurality of circular holes opened on the second roller, a rotating rod rotatably mounted on the column, a drive sprocket fixed at the other end of the rotating rod, and a transmission chain installed between the drive sprocket, the first roller and the second roller;

[0004] The above technical solution adjusts the rotation speed of the first and second rollers to match the conveying speed of the thermal paper during the conveying process, which allows punching to be performed during high-speed conveying, preventing tearing at the punching position and improving the punching effect. However, the operation of the rollers causes the original cutter on the rollers to flip, resulting in tearing of the thermal paper. Furthermore, it is not convenient for the thermal paper to be continuously conveyed for punching. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for processing thermal paper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A punching device for processing thermal paper includes a processing table. A slot is provided in the middle of the front face of the processing table near the bottom. A storage box for collecting debris is provided in the slot. A tray is provided in the middle of the processing table above the storage box. Rotary rollers are symmetrically arranged on both sides of the processing table above the tray. Conveyor belts are symmetrically arranged on both sides of the processing table. Positioning plates are symmetrically arranged on the upper surface of the processing table near the left side. A top plate is provided between the positioning plates. A pressing roller for pressing thermal paper is provided below the top plate. A support plate is also provided in the middle of the processing table. A punching assembly is provided on the support plate.

[0008] The drilling assembly includes an electric push rod and a movable plate at the end of the telescopic arm of the electric push rod. A T-slot is provided on the front end face of the movable plate, and a drilling plate for disassembly and replacement is provided in the T-slot. Several circular cutters are provided on the lower surface of the drilling plate.

[0009] Furthermore, the rotating roller is rotatably connected to the processing table via a rotating shaft, wherein the rotating shaft of the rotating roller near the middle position extends out of the processing table, and one end of the extension is provided with a toothed disc, and a toothed belt is provided between the two toothed discs. A motor is provided on the outer wall of the processing table, and the motor is fixedly connected to the processing table by screws. The output shaft of the motor is coaxially connected to the rotating shaft of one of the rotating rollers.

[0010] In this invention, the motor is electrically connected to an external power source via wires, and a control switch is fitted on the outer wall of the motor. When the control switch is activated, the output shaft of the motor rotates, driving the rollers to rotate. The toothed belt meshes with the corresponding toothed disc, enabling the two sets of rollers to rotate synchronously. The conveyor belts are respectively fitted onto the two sets of rollers. Under the action of friction, the rotation of the rollers drives the two conveyor belts to move synchronously towards each other. The upper surface of the conveyor belt is placed with corresponding thermal paper that needs to be perforated, facilitating continuous conveying.

[0011] Specifically, the width of the inner wall of the slot is adapted to the width of the outer wall of the storage box, and a handle is provided on the outer wall of the storage box.

[0012] In this invention, the handle provides a point of leverage, making it easy to manually pull out the storage box for centralized cleaning of the collected drilling debris. The storage box receives the drilling debris discharged from the bottom of the tray, reducing debris falling and impacting the surrounding environment.

[0013] It should be noted that the side wall of the pallet is fixedly connected to the processing table by screws, and arc-shaped grooves are opened at both ends of the pallet. The ends of the conveyor belt are tightly connected to the arc-shaped grooves. Several through holes are opened on the upper surface of the pallet, and the through holes are interconnected with the interior of the storage box.

[0014] In this invention, the two arc-shaped grooves work together to facilitate the tight fit between the two sides of the pallet and the corresponding outer wall of the conveyor belt. The perforations facilitate the drilling of thermal paper, and the perforations correspond to the storage box, which helps the debris from the drilling to fall into the storage box.

[0015] Furthermore, the bottom of the positioning plate is fixedly connected to the processing table by screws, and the top plate is fixedly connected to the top of the positioning plate by screws. Each of the two positioning plates has a sliding groove on its opposite side, and a U-shaped plate is provided between the two sliding grooves.

One end of the spring is combined and fixed to the top of the U-shaped plate, and the other end is combined and fixed to the bottom of the top plate.

[0016] In this invention, the U-shaped plate slides between two grooves, and the U-shaped plate with the pressing roller moves vertically. With the help of the spring on the U-shaped plate, the U-shaped plate can move up and down flexibly, and can stably press and convey thermal paper of different thicknesses.

[0017] Furthermore, the support plate is L-shaped, and the bottom of the support plate is fixedly connected to the top of the processing table by screws. Support columns are symmetrically provided on the lower surface of the support plate near the front end. The top of the support columns is fixed to the support plate by screws, and the bottom of the support columns is fixed to the processing table by screws.

[0018] In this invention, a support column is used on the support plate to increase the stability of the support plate installation and to provide a stable point of force.

[0019] It is worth noting that the electric push rod is fixed to the top of the support plate by screws, the telescopic arm slides with the support plate, the end of the telescopic arm is fixedly connected to the movable plate by screws, and the width of the inner wall of the T-slot is adapted to the width of the outer wall of the perforated plate.

[0020] In this invention, the electric push rod is electrically connected to an external power source via a wire. When the control switch on the outer wall of the electric push rod is activated, the telescopic arm extends, causing the movable plate to move downward. The perforated plate is inserted into the T-slot, facilitating the removal and replacement of the perforated plate. The number of perforations on the thermal paper can be adjusted by replacing the circular cutters with different numbers of them.

[0021] In addition, the circular cutters are evenly spaced and correspond to the perforations. A handle groove is provided on the front end face of the perforation plate, and screw holes are provided on both sides of the perforation plate, with fastening bolts provided in each screw hole.

[0022] In this invention, the handle groove provides a leverage point for the installation or removal of the movable plate, and the fastening bolt passes through the side wall of the perforated plate and is threadedly connected to the screw hole, thereby achieving a stable installation and fit between the perforated plate and the movable plate.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This utility model features a processing table with a storage box, two sets of rotating rollers that work with conveyor belts, and a motor that provides output power. With the cooperation of the toothed disc and the toothed belt, the two conveyor belts move synchronously towards each other. A U-shaped plate with a pressing roller moves vertically below the top plate with the help of a spring, which stably presses and conveys thermal paper of different thicknesses conveyed on the left conveyor belt. The telescopic arm of the electric push rod drives the movable plate with a perforated plate to move up and down. The circular cutter is inserted and connected to the tray to perforate the thermal paper conveyed to the tray.

[0025] 2. This utility model collects debris falling from the perforations on the pallet by setting up a storage box, reducing the impact on the surrounding environment. The fastening bolt passes through the side wall of the movable plate and is threaded into the screw hole on the perforated plate to achieve the combination and fixation of the movable plate and the perforated plate. With the help of the pull handle, it is convenient to pull out and install the storage box. The two arc grooves on the pallet are respectively tightly attached to one end of the corresponding conveyor belt, which facilitates the horizontal, stable and continuous conveying and guiding of the thermal paper.
