Description

Technical Field

[0001] This utility model relates to the field of nailing machine technology, and in particular to a flipping mechanism for a nailing machine. Background Technology

[0002] As a core piece of equipment in the packaging industry, carton stapling machines are widely used in processes such as carton forming, stapling, and flipping. The flipping mechanism is a key component for achieving double-sided stapling of cartons. With the rapid development of e-commerce logistics, the demand for cartons has surged, placing higher demands on the efficiency and quality of carton stapling machines. Traditional flipping mechanisms require frequent clamping and flipping of cartons during high-speed operation. However, carton materials are fragile and easily deformed, especially during transmission, where mechanical impact can easily cause surface damage or edge cracking, affecting the finished product qualification rate. Therefore, developing a flipping mechanism that combines high efficiency and protection has become an urgent need in the industry, aiming to balance production efficiency and carton integrity, and adapt to diverse carton processing scenarios.

[0003] Most existing carton stapling machines employ rigid clamping structures for their flipping mechanisms. These mechanisms use cylinders or motors to drive metal clamps that directly grip the carton, and a rotating mechanism completes the 180° flipping motion. The underlying technology relies on the synchronous movement and precise positioning of the clamps. Mechanical linkage ensures the carton rotates stably on the transport track. Some machines add photoelectric sensors to detect the carton's position and control the clamping timing. Furthermore, the transmission system often uses chains or belts with gear sets to achieve power transmission and speed adjustment. While this design can meet the basic flipping function, it lacks a dynamic buffering mechanism during the clamping process, and the rigid contact between the carton and the metal clamps can easily become a potential source of damage.

[0004] The core defect of traditional carton stapling machine flipping mechanisms lies in insufficient cushioning performance. Since the clamps are usually made of metal and are fixedly installed, when the carton enters the clamping area, its sidewalls will be subjected to a large impact force instantly. Especially when running at high speed or when the carton thickness is uneven, the impact force can cause indentations on the carton surface, cracks at the edges, or even structural deformation. This problem is more prominent when processing high-strength or high-grammage cartons, which not only reduces the quality of the finished product but also requires frequent machine stops to deal with damaged cartons, seriously affecting production efficiency. Therefore, how to optimize the cushioning performance of the clamping structure has become a key challenge to improve the reliability of the flipping mechanism. To this end, a new flipping mechanism for carton stapling machines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flipping mechanism for a carton nailing machine, which aims to improve the problem that the traditional flipping mechanism of a carton nailing machine lacks effective buffering, causing the carton to be easily damaged by impact during transportation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flipping mechanism for a nailing machine, comprising a base, a support frame fixedly connected to the top of the base, a rotating rod rotatably connected inside the support frame, a motor fixedly connected to the outer wall of the support frame, the output end of the motor fixedly connected to one end of the rotating rod, a clamping block one provided on the outer wall of the rotating rod, a clamping block two provided on the outer wall of the rotating rod, a fixing plate slidably connected inside both clamping block one and clamping block two, and a buffer assembly provided inside both clamping block one and clamping block two;

[0007] The buffer assembly includes a damper and a spring 1 sleeved on the outer wall of the damper. One end of the damper is fixedly connected to the inner wall of the clamping block 1, and the output end of the damper is fixedly connected to the side wall of the fixed plate. One end of the spring 1 is fixedly connected to the inner wall of the clamping block 1, and the other end of the spring 1 is fixedly connected to the side wall of the fixed plate. A rubber pad is fixedly connected to the other side of the fixed plate. Quick-release assemblies are provided on the outer walls of both the clamping block 1 and the clamping block 2.

[0008] As a further description of the above technical solution:

[0009] The quick-release assembly includes a hollow column and a sliding column. The outer wall of the sliding column is slidably connected to the inside of the hollow column, and the outer wall of the hollow column is fixedly connected to the inside of the clamping block.

[0010] As a further description of the above technical solution:

[0011] Both clamping blocks 1 and 2 have fixedly connected to their outer walls, and both clamping blocks 1 and 2 have slots inside.

[0012] As a further description of the above technical solution:

[0013] The card block has a card hole inside, and the card block and the card slot engage.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the sliding column is slidably connected to the inside of the locking block, and the sliding column and the locking hole are engaged;

[0016] As a further description of the above technical solution:

[0017] A pull block is fixedly connected to one end of the sliding column, and a connecting block is fixedly connected to the outer wall of the sliding column. The connecting block is in contact with the hollow column.

[0018] As a further description of the above technical solution:

[0019] The hollow column is fixedly connected to a limiting block one, the outer wall of the sliding column is slidably connected to the inner wall of the limiting block one, and the outer wall of the sliding column is fixedly connected to a limiting block two, the outer wall of the limiting block two is slidably connected to the inner wall of the hollow column.

[0020] As a further description of the above technical solution:

[0021] A second spring is provided on the outer wall of the sliding column. One end of the second spring is fixedly connected to one side wall of the limiting block, and the other end of the second spring is fixedly connected to the side wall of the limiting block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the carton enters between clamping block one and clamping block two, the outer wall of the carton first contacts the rubber pad, effectively preventing damage to the carton after contact between clamping block one and clamping block two. At the same time, the buffer assembly composed of damper and spring one effectively absorbs the impact force generated when the carton enters, thereby reducing the impact force on the carton. This solves the problem that the traditional carton turning mechanism lacks effective buffering, causing the carton to be easily damaged by impact during transmission, and improves the protection of the carton during the turning process.

[0024] 2. In this utility model, by pulling the pull block, the pull block causes the sliding column to move inside the hollow column. At this time, the first limiting block and the second limiting block compress the second spring, causing the second spring to store elastic potential energy. Subsequently, the sliding column is released from the restriction of the internal locking hole of the locking block. At this time, pulling the second clamping block upward can separate the first clamping block and the second clamping block, thereby achieving the effect of quickly disassembling the first clamping block and the second clamping block. This solves the problem that the traditional nailing machine clamping blocks are complicated in fixing method and cumbersome in disassembly process, resulting in time-consuming and labor-intensive equipment maintenance and low efficiency in replacing worn parts. It improves the convenience of equipment maintenance and production flexibility, greatly reduces downtime maintenance time, and improves overall production efficiency. Attached Figure Description

A rotating rod 4 is rotatably connected inside the support frame 2, and a motor 3 is fixedly connected to the outer wall of the support frame 2. The output end of the motor 3 is fixedly connected to one end of the rotating rod 4 to drive the rotating rod 4 to rotate and achieve carton flipping.

A fixing plate 9 is slidably connected inside both the first clamping block 5 and the second clamping block 6, and the fixing plate 9 is used to contact the carton and transmit clamping force. A buffer assembly is provided inside both the first clamping block 5 and the second clamping block 6 to absorb the impact force when the carton enters.

[0034] The cushioning assembly includes a damper 7 and a spring 8 sleeved on the outer wall of the damper 7. One end of the damper 7 is fixedly connected to the inner wall of the clamping block 5, and the output end of the damper 7 is fixedly connected to the side wall of the fixing plate 9, used to reduce the impact vibration when the carton enters. One end of the spring 8 is fixedly connected to the inner wall of the clamping block 5, and the other end of the spring 8 is fixedly connected to the side wall of the fixing plate 9, used to provide elastic support and assist in cushioning. A rubber pad 10 is fixedly connected to the other side of the fixing plate 9, used to directly contact the surface of the carton to prevent damage during clamping. The outer walls of both the clamping block 5 and the clamping block 6 are equipped with quick-release components for easy disassembly and maintenance.

[0035] Reference Figures 4-5The quick-release assembly includes a hollow column 14 and a sliding column 15. The outer wall of the sliding column 15 is slidably connected to the interior of the hollow column 14, and the outer wall of the hollow column 14 is fixedly connected to the interior of clamping block 1 5, providing sliding guidance. Clamping blocks 11 are fixedly connected to the outer walls of clamping blocks 1 5 and 2 6, respectively. Clamping blocks 1 5 and 2 6 each have a slot 13 inside, and clamping blocks 11 have a hole 12 inside. The clamping blocks 11 and slots 13 engage to fix the relative positions of clamping blocks 1 5 and 2 6. The outer wall of the sliding column 15 is slidably connected to the interior of the clamping block 11, and the sliding column 15 engages with the hole 12 to lock the connection state of clamping blocks 1 5 and 2 6. A pull block 16 is fixedly connected to one end of the sliding column 15 for manual operation of its movement. A connecting block 17 is fixedly connected to the outer wall of the sliding column 15, and the connecting block 17 contacts the hollow column 14 to limit the stroke of the sliding column 15. A limiting block 18 is fixedly connected inside the hollow column 14, and the outer wall of the sliding column 15 is slidably connected to the inner wall of the limiting block 18 to ensure the stable movement of the sliding column 15.

One end of the spring 20 is fixedly connected to the side wall of the limiting block 18, and the other end of the spring 20 is fixedly connected to the side wall of the limiting block 29 to provide a reset force, ensuring that the sliding column 15 automatically returns to its position and remains in the engaged state.

[0036] Working principle: When the carton is conveyed by the conveyor belt to the space between clamping blocks 5 and 6, the outer wall of the carton first contacts the rubber pad 10. The flexible material of the rubber pad 10 prevents damage to the carton surface due to rigid contact. At the same time, the impact force generated when the carton enters pushes the fixing plate 9 inward, causing the spring 8 to compress and drive the damper 7 to contract. The buffer assembly absorbs the impact energy through elastic deformation and damping, ensuring that the carton enters the clamping area smoothly. Clamping blocks 5 and 6 remain relatively fixed when the motor 3 is not running, ensuring that the carton is stably clamped and will not fall off. This effectively reduces the risk of carton breakage caused by instantaneous impact in traditional flipping mechanisms and improves the stability of the carton. For protection during high-speed transmission, once the carton is stably clamped, motor 3 starts and drives rotating rod 4 to rotate, causing clamping block 5 and clamping block 6 to rotate synchronously, achieving a 180° flip of the carton. When maintenance or replacement of clamping block 5 and clamping block 6 is required, the pull block 16 can be pulled to move sliding column 15 inside hollow column 14. At this time, limiting block 18 and limiting block 29 compress spring 20, causing spring 20 to store elastic potential energy. Subsequently, sliding column 15 is released from the restriction of the locking hole 12 inside the locking block 11. At this time, pulling clamping block 6 upward can separate clamping block 5 and clamping block 26, thereby achieving the purpose of quickly disassembling clamping block 5 and clamping block 26.
