Description

Technical Field

[0001] This utility model relates to the field of label printing cutting technology, specifically to a label printing cutting device with adjustable spacing. Background Technology

[0002] An adjustable-spacing label printing cutting device is a practical piece of equipment for post-printing label processing. It mainly consists of a frame, a cutting blade shaft system, and an adjustment mechanism. The frame provides a stable foundation for overall operation. The cutting blade shaft system contains multiple sets of cutting blades for efficient label cutting. The key adjustment mechanism is ingeniously designed, allowing for quick and precise adjustment of the blade shaft spacing according to different label sizes and cutting requirements. It can easily handle both large and small labels through adjustment. Furthermore, the device is equipped with an intelligent control system that allows for setting cutting parameters to ensure cutting accuracy and efficiency. Its simple operation effectively solves the problem of frequent shaft or machine replacements required by traditional cutting devices with fixed blade shaft spacing.

[0003] In existing label cutting technologies, the shape of the common cutting blade shaft is fixed, lacking the ability to flexibly adjust the blade shaft spacing according to label cutting requirements. This limitation means that when faced with cutting tasks of different sized labels, the only option is to replace the entire cutting machine or disassemble and replace the blade shaft. These operations are not only cumbersome and complex, but also consume a lot of time and manpower, seriously affecting production efficiency. This fixed type of blade shaft cannot adapt to diverse production needs, greatly reducing its practicality. In order to solve this technical problem, this utility model proposes a label printing cutting device with adjustable spacing. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In existing label cutting technologies, the shape of the common cutting blade shaft is fixed, lacking the ability to flexibly adjust the blade shaft spacing according to label cutting requirements. This limitation means that when faced with cutting tasks of different sized labels, the only option is to replace the entire cutting machine or disassemble and replace the blade shaft. These operations are not only cumbersome and complex, but also consume a lot of time and manpower, seriously affecting production efficiency. This fixed type of blade shaft cannot adapt to diverse production needs, greatly reducing its practicality. In order to solve this technical problem, this utility model proposes a label printing cutting device with adjustable spacing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable spacing label printing cutting device, comprising a support frame, an electric push rod fixedly connected to the top of the support frame, a fixed frame fixedly connected to the output end of the electric push rod, an inner plate fixedly connected inside the fixed frame, a motor fixedly connected to the top of the inner plate, a rotating shaft fixedly connected to the output end of the motor, a gear fixedly connected to the outer wall of the bottom end of the rotating shaft, a pair of limiting blocks fixedly connected to the lower part of the fixed frame, a rack slidably connected inside each limiting block, and both sides of the rack meshing with the gear, a connecting plate fixedly connected to the bottom of the other end of each rack, and a cutting blade fixedly connected to the bottom of each connecting plate.

[0008] Preferably, a support block is fixedly connected to one end of the outer wall of each rack, and an inner groove is opened inside the fixing frame, which corresponds to the support block, while the support block is slidably connected in the inner groove.

[0009] Preferably, each of the connecting plates has a protrusion fixedly connected to the top of one side, and the bottom of the fixing frame has a groove corresponding to the protrusion, while the protrusion is slidably connected in the groove.

[0010] Preferably, each of the connecting plates has a fixing plate fixedly connected to its outer side wall.

[0011] Preferably, a telescopic rod is fixedly connected inside the fixed plate, and a pressure plate is fixedly connected to the other end of the telescopic rod. A spring is sleeved on the outer wall of the telescopic rod, and the spring is fixedly connected between the fixed plate and the pressure plate.

[0012] Preferably, a base is fixedly connected to the bottom of the support frame, and a pair of positioning rods are fixedly connected to the top of the fixed frame, with the positioning rods slidably connected inside the support frame.

[0013] (III) Beneficial Effects

[0014] This invention provides a label printing cutting device with adjustable spacing. It has the following advantages:

[0015] (1) Start the motor on the inner plate to drive the rotating shaft and gear to rotate. The gear drives the racks on both sides to move in opposite directions in the inner groove. The support block limits the direction to ensure consistency. The limit block supports the rack. The rack moves and drives the connecting plate. The connecting plate moves smoothly in the groove through the protrusion, thereby driving the cutting blade to adjust the spacing. The fixed frame connects the components. The electric push rod drives it to move down so that the cutting blade can cut. This device solves the problem that the existing label cutting device is difficult to adjust the cutting width quickly. The traditional device is complicated to adjust and inefficient. This structure achieves fast and accurate adjustment through the cooperation of components, improves cutting efficiency and flexibility, and ensures cutting quality.

[0016] (2) The fixing plate is used to fix the telescopic rod. One end of the telescopic rod is connected to the pressure plate. The spring is sleeved on the telescopic rod. During cutting, the pressure plate contacts the label first. As the cutting action proceeds, the pressure plate is squeezed and moves upward, compressing the telescopic rod and the spring. The spring is compressed and the rebound force generated is transmitted to the pressure plate through the telescopic rod, so that the pressure plate applies greater pressure to the label. This structure solves the problem of easy curling of the label during the cutting of existing labels. In traditional cutting, the label is not fixed firmly and is easy to curl, which affects the quality. This structure enhances the fixing effect of the label through the cooperation of the fixing plate, telescopic rod, spring and pressure plate, effectively avoids the curling phenomenon, and improves the quality and yield of the cut label.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A cutting device for adjustable spacing label printing includes a support frame 1. An electric push rod 2 is fixedly connected to the top of the support frame 1. A fixed frame 3 is fixedly connected to the output end of the electric push rod 2. An inner plate 4 is fixedly connected inside the fixed frame 3. A motor 5 is fixedly connected to the top of the inner plate 4. A rotating shaft 6 is fixedly connected to the output end of the motor 5. A gear 7 is fixedly connected to the outer wall of the bottom end of the rotating shaft 6. A pair of limiting blocks 9 are fixedly connected to the lower part of the fixed frame 3. A rack 8 is slidably connected inside each limiting block 9, and both sides of the rack 8 mesh with the gear 7. A connecting plate 12 is fixedly connected to the bottom of the other end of each rack 8. Each connecting plate 12 has a cutting blade 13 fixedly connected to its bottom. Each rack 8 has a support block 10 fixedly connected to one end of its outer wall. The fixing frame 3 has an inner groove 11, which corresponds to the support block 10. The support block 10 is slidably connected to the inner groove 11. Each connecting plate 12 has a protrusion 15 fixedly connected to one side of its top. The fixing frame 3 has a groove 14 at its bottom, which corresponds to the protrusion 15. The protrusion 15 is slidably connected to the groove 14. The fixing frame 3 has a pair of positioning rods 23 fixedly connected to its top. The support frame 1 has a base 22 fixedly connected to its bottom. The positioning rods 23 are slidably connected to the support frame 1.

[0025] When it is necessary to adjust the cutting blades 13 on both sides according to the label length, the motor 5 at the top of the inner plate 4 is activated. The motor 5 operates, driving the gear 7 on the rotating shaft 6 to rotate. When the gear 7 rotates, it drives the racks 8 on both sides to move in opposite directions. During the movement, the racks 8 are limited by the support block 10 and move within the inner groove 11 to ensure consistent movement direction. At the same time, the limiting block 9 supports the racks 8. The movement of the racks 8 will drive the connecting plates 12 at their bottom to move in opposite directions, thereby realizing the adjustment of the cutting blades 13 on both sides. When the connecting plates 12 move, the protrusion 15 is limited within the groove 14. After the adjustment is completed, the electric push rod 2 at the top of the support frame 1 is activated. The electric push rod 2 drives the fixed frame 3 to move down, causing the cutting blades 13 to move down to cut the label. These components work together to realize the rapid adjustment of the cutting blades 13 on both sides, effectively improving work efficiency.

[0026] Example 2: The difference between this example and Example 1 is that each connecting plate 12 is fixedly connected to a fixing plate 16 on its outer side wall, a telescopic rod 19 is fixedly connected inside the fixing plate 16, a pressure plate 21 is fixedly connected to the other end of the telescopic rod 19, and a spring 20 is sleeved on the outer wall of the telescopic rod 19. At the same time, the spring 20 is fixedly connected between the fixing plate 16 and the pressure plate 21.

[0027] When the cutting blade 13 moves downwards to perform the cutting operation, the pressure plates 21 on both sides of the connecting plate 12 first come into contact with the label. Subsequently, as the cutting blade 13 continues to move downwards, the pressure plates 21 are compressed and move upwards. As the pressure plates 21 move upwards, they compress the connected telescopic rod 19 and simultaneously compress the spring 20. The spring 20 has resilience and generates a reaction force after compression, causing the pressure plates 21 to apply stronger pressure to the label. In this way, it is ensured that no curling occurs during label cutting, effectively improving product quality.

[0028] Working principle: When the staff needs to cut the printed labels, the cutting blades 13 on both sides are adjusted according to the length of the label. At this time, the motor 5 on the top of the inner plate 4 is started. Under the action of the motor 5, the gear 7 on the rotating shaft 6 is rotated. When the gear 7 rotates, it will drive the racks 8 on both sides to move in opposite directions. When the racks 8 move, they are limited in the inner groove 11 by the support block 10 to ensure that the direction of movement is consistent. The limiting block 9 will support the racks 8. When the racks 8 move, they will drive the connecting plates 12 at their bottom to move in opposite directions, thereby adjusting the cutting blades 13 on both sides. When the connecting plates 12 move, they are connected by the protrusion 1. 5 is limited within the groove 14, and works with the electric push rod 2 at the top of the starting support frame 1 to drive the fixed frame 3 to move down, thereby driving the cutting blade 13 to move down and cut the label. Through their cooperation, the cutting blades 13 on both sides can be quickly adjusted, improving work efficiency. When the cutting blade 13 moves down to cut, the pressure plates 21 on both sides of the connecting plate 12 first contact the label. As the cutting blade 13 continues to move down, the pressure plates 21 are squeezed and moved up, which will compress the telescopic rod 19 and the spring 20. The elasticity of the spring 20 will make the pressure plate 21 stronger, thereby ensuring that the label will not curl up during cutting and improving product quality.
