A punch component for nailing cardboard boxes

Abstract

This utility model discloses a punch component for carton stapling, relating to the field of carton stapling production equipment. It includes a head fixing plate, a punch drive plate, and a punch rod. The punch drive plate is slidably mounted on the punch fixing plate. One end of the punch drive plate is connected to the punch rod. A separation groove is formed at the end of the punch rod away from the punch drive plate. The separation groove allows two punch heads to be formed at the end of the punch rod away from the punch drive plate, enabling the synchronous stapling of two staples in a single punching action, breaking the limitations of the traditional single-stapling punching mode. When facing multi-row stapling or high-density stapling requirements, multiple reciprocating movements are eliminated, significantly shortening the processing time per carton, effectively improving the overall cycle time of the production line, reducing energy consumption and equipment wear caused by high-frequency ineffective idle movements, and thus reducing production and operating costs.

Description

Technical Field

[0001] This utility model relates to the field of cardboard box punching production equipment, specifically a punch component for cardboard box nailing. Background Technology

[0002] In the corrugated box packaging industry, the stapling machine is a key piece of equipment for achieving rapid sealing of corrugated boxes. Its working efficiency and stapling quality directly affect the overall capacity and product qualification rate of the packaging production line. The punch component, as the core actuator of the stapling machine to complete the stapling action, undertakes the important function of driving the stapling wires to penetrate the cardboard and complete the bending and forming. Its structural stability, motion precision, and ease of assembly play a decisive role in the performance of the stapling machine.

[0003] Currently, the punch components of common carton stapling machines on the market still have many technical pain points in practical applications. Among them, existing punch components are generally limited to completing the stitching of only one staple in a single punching motion, which is significantly different from the high-speed and high-efficiency requirements of modern packaging production lines. When facing carton packaging needs requiring multi-row or high-density stitching, the punch component in the single-stapling punching mode needs to perform multiple reciprocating motions to complete the sealing operation of a carton. This not only significantly extends the processing time per carton and reduces the overall cycle time of the production line, but also increases energy consumption and wear due to the high-frequency ineffective idle motion of the punch, thus increasing production and operating costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a punch component for nailing cardboard boxes, thereby solving the deficiencies of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a punch component for nailing cartons, comprising a punch fixing plate, a punch driving plate and a punch rod, wherein the punch driving plate is slidably mounted on the punch fixing plate, one end of the punch driving plate is connected to the punch rod, and a separation groove is provided at the end of the punch rod away from the punch driving plate, the separation groove being used to form two punch heads at the end of the punch rod away from the punch driving plate.

[0006] Furthermore, the punch drive plate has a small-sized slot and a large-sized slot connected at one end near the punch rod. The large-sized slot is located near the center of the punch drive plate. Both the small-sized slot and the large-sized slot are arranged through the punch drive plate along its thickness direction. A middle mounting block is fixed at the end of the punch rod away from the punch head. A tail mounting block is fixed at the middle mounting block. The tail mounting block is adapted to fit in the large-sized slot, and the middle mounting block is adapted to fit in the small-sized slot.

[0007] Furthermore, it also includes a guide plate, which is fixedly connected to the punch fixing plate. The top and bottom surfaces of the guide plate are provided with sliding grooves, which are arranged through the punch rod along the moving direction. The two punch heads of the punch rod are respectively slidably adapted into the two sliding grooves.

[0008] Furthermore, a limiting groove is formed on the side wall of the slide, and a slide bar is fixed on the side wall of the punch rod, the slide bar being slidably adapted within the limiting groove.

[0009] Furthermore, the top surface of the punch fixing plate is provided with a positioning groove, the bottom of the guide plate is fixed with a positioning block, the positioning groove is provided with a threaded hole, and the guide plate is provided with a countersunk hole. When the positioning block is fitted into the positioning groove, the countersunk hole is coaxial with the threaded hole, and the bolt passes through the countersunk hole and is threaded into the threaded hole.

[0010] Furthermore, an inverted T-shaped slide rail is fixed to the bottom of the punch drive plate, and an inverted T-shaped slide groove is provided on the top surface of the punch fixing plate. The inverted T-shaped slide groove is provided through the punch rod in the direction of movement, and the inverted T-shaped slide rail is slidably adapted to the inverted T-shaped slide groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. By creating a separation groove at the end of the punch rod away from the punch drive plate, two punch heads are formed, enabling the synchronous engagement of two nails in a single punching action, breaking the limitations of the traditional single-nail punching mode. When facing multi-row or high-density nailing requirements, multiple reciprocating movements are eliminated, significantly shortening the processing time per box, effectively improving the overall cycle time of the production line, reducing energy consumption and equipment wear caused by high-frequency ineffective idle movements, and thus reducing production and operating costs.

[0013] 2. The punch drive plate features small and large slots. The punch rod is fitted into the small slot via a middle mounting block and into the large slot via a stepped mounting structure. Compared to traditional single bolt fastening or welding connections, this increases the contact area and connection strength between the punch rod and the drive plate. This structure effectively resists the impact and torque generated by the punch rod during high-frequency reciprocating motion, preventing problems such as bolt loosening, punch rod misalignment, or detachment. This ensures the accuracy of the nail box, reduces equipment downtime, and facilitates punch rod disassembly and replacement, lowering maintenance costs and simplifying repair procedures.

Detailed Implementation

[0021] Example 1

[0022] like Figures 1 to 6 As shown, a punch component for nailing cartons includes a punch fixing plate 1, a punch driving plate 2, and a punch rod 3. The punch driving plate 2 is slidably mounted on the punch fixing plate 1. One end of the punch driving plate 2 is connected to the punch rod 3. A separation groove 4 is provided at the end of the punch rod 3 away from the punch driving plate 2. The separation groove 4 is used to form two punch heads 7 at the end of the punch rod 3 away from the punch driving plate 2. The punch driving plate 2 is used to connect a power component, such as a cylinder. The telescopic shaft of the cylinder is connected to the punch driving plate 2. The punch fixing plate 1 is fixedly mounted on the nailing device by bolts. By replacing the punch structure in the nailing device with the punch component of this application, since the punch rod 3 forms two punch heads 7, the synchronous nailing of two nails can be completed in one punching action, breaking the limitations of the traditional single-nail punching mode. When faced with multi-row or high-density stapling requirements, the need for multiple reciprocating movements is eliminated, significantly shortening the processing time per box, effectively improving the overall cycle time of the production line, reducing energy consumption and equipment wear caused by high-frequency ineffective idle movements, and thus reducing production and operating costs.

[0023] Furthermore, an inverted T-shaped slide rail 18 is fixed to the bottom of the punch drive plate 2, and an inverted T-shaped slide groove 19 is provided on the top surface of the punch fixing plate 1. The inverted T-shaped slide groove 19 is provided through the punch rod 3 along the moving direction. The inverted T-shaped slide rail 18 is slidably adapted to the inverted T-shaped slide groove 19. The movement of the punch drive plate 2 is guided by the cooperation between the inverted T-shaped slide rail 18 and the inverted T-shaped slide groove 19, and the punch drive plate 2 is prevented from detaching from the punch fixing plate 1.

[0024] Example 2

[0025] Based on Example 1, such as Figures 1 to 3 As shown, the punch drive plate 2 has a small-sized slot 5 and a large-sized slot 6 connected at one end near the punch rod 3. The large-sized slot 6 is located near the center of the punch drive plate 2. Both the small-sized slot 5 and the large-sized slot 6 are arranged through the punch drive plate 2 along its thickness direction. A middle mounting block 8 is fixed at the end of the punch rod 3 away from the punch head 7. A tail mounting block 9 is fixed at the middle mounting block 8. The tail mounting block 9 fits into the large-sized slot 6, and the middle mounting block 8 fits into the small-sized slot 5. The punch rod 3 is installed along the thickness direction of the punch drive plate 2, so that the tail mounting block 9 fits into the large-sized slot 6 and the middle mounting block 8 fits into the small-sized slot 5, forming a stepped installation structure. Compared with the traditional single bolt fastening or welding connection method, this increases the contact area and connection strength between the punch rod 3 and the punch drive plate 2. This structure can effectively resist the impact and torque generated by the punch rod 3 during high-frequency reciprocating motion, avoiding problems such as loose bolts, displacement or detachment of the punch rod 3, ensuring the accuracy of the nail box, reducing equipment downtime due to malfunctions, and facilitating the disassembly and replacement of the punch rod, thereby reducing maintenance costs and the complexity of repair procedures.

[0026] Example 3

[0027] Based on Example 2, such as Figures 1 to 5 As shown, it also includes a guide plate 10, which is fixedly connected to the punch fixing plate 1. The top and bottom surfaces of the guide plate 10 are provided with sliding grooves 11, which are arranged through the punch rod 3 along the moving direction. The two punch heads 7 of the punch rod 3 are respectively slidably adapted to the two sliding grooves 11. The side wall of the sliding groove 11 is provided with a limiting sliding groove 12. The side wall of the punch rod 3 is fixed with a slide bar 13, which is slidably adapted to the limiting sliding groove 12. Through the cooperation of the slide bar 13 and the limiting sliding groove 12, the punch rod 3 and the punch drive plate 2 will not separate in the thickness direction. Through the joint action of the punch drive plate 2 and the guide plate 10, the punch rod 3 can only move in a straight line along the direction of the sliding groove 11. While ensuring a large-area connection between the punch drive plate 2 and the punch rod 3, the guide plate 10 can also prevent the punch rod 3 from separating from the punch drive plate 2.

[0028] Example 4

[0029] Based on Example 3, such as Figures 1 to 6 As shown, a positioning groove 14 is provided on the top surface of the punch fixing plate 1, and a positioning block 15 is fixed on the bottom of the guide plate 10. A threaded hole 16 is provided in the positioning groove 14, and a countersunk hole 17 is provided on the guide plate 10. When the positioning block 15 is fitted into the positioning groove 14, the countersunk hole 17 is coaxial with the threaded hole 16. The bolt passes through the countersunk hole 17 and is threaded into the threaded hole 16. The positioning of the threaded hole 16 and the countersunk hole 17 is completed by the cooperation of the positioning block 15 and the positioning groove 14. Then, the guide plate 10 and the punch fixing plate 1 are connected together by bolts. The installation is simple and easy to disassemble. During installation, the punch drive plate 2 is first installed on the punch fixing plate 1, so that the inverted T-shaped slide rail 18 is fitted into the inverted T-shaped slide groove 19. Then, the punch rod 3 is assembled with the guide plate 10 so that the two punches are connected. Part 7 is fitted into the two slide grooves 11, and slide bar 13 is fitted into the limiting slide groove 12. Then, punch rod 3 is assembled along the thickness direction of punch drive plate 2, so that middle mounting block 8 is fitted into small size groove 5, tail mounting block 9 is fitted into large size groove 6, and positioning block 15 is fitted into positioning groove 14. Finally, guide plate 10 is connected to punch fixing plate 1 by bolts. Assembly is simple. When disassembling, unscrew the bolts and separate guide plate 10 and punch fixing plate 1 along the thickness direction to separate punch rod 3 from punch drive plate 2. Then slide punch drive plate 2 along the length direction of inverted T-shaped slide groove 19 to separate punch drive plate 2 from punch fixing plate 1. Move punch rod 3 along the length direction of slide groove 11 to separate punch rod 3 from guide plate 10 to complete disassembly.
