Description

Technical Field

[0001] This invention relates to the field of packaging paperboard processing technology, and in particular to a device for edge cutting of stacked packaging paperboard. Background Technology

[0002] In the processing of packaging cardboard, side cutting of stacked cardboard is a crucial forming process, requiring smooth and uniform cut edges to meet subsequent processing needs. Currently, the industry mostly uses manual assistance or simple equipment for edge cutting of stacked cardboard, which has several obvious drawbacks: manual positioning and pushing of cardboard easily leads to cardboard misalignment and warping, resulting in low cutting accuracy and uneven cut edges; most equipment lacks reliable clamping and pressing mechanisms, causing cardboard to wobble with the saw blade during cutting, significantly reducing the yield rate; the material support structure has poor adjustment flexibility, making it unable to quickly adapt to the processing needs of different cardboard specifications, resulting in cumbersome debugging and low processing efficiency; manually pushing cardboard directly to the cutting area is not only labor-intensive but also poses a safety hazard of accidental hand injury from the saw blade; and the positioning of the support plate and the cutting saw in some equipment is not properly matched, easily leading to incomplete cutting and saw blade scraping of the cardboard or support plate.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a stacked packaging cardboard edge cutting device, which would make it more industrially valuable. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a device for edge-cutting stacked packaging cardboard.

[0005] The present invention provides a stacked packaging cardboard edge cutting device, comprising a base installed on the ground, a movable support seat provided on the upper surface of the base, a material seat that can move back and forth provided on the upper surface of the support seat, a horizontally arranged material support plate provided on the front surface of the material seat, and a cutting table provided on one side of the base in front of the material support plate, wherein a cutting electric saw for cutting is provided on the cutting table.

[0006] This device is equipped with a base that serves as the foundation for overall installation and is placed on the ground. The upper surface of the base is equipped with a support seat that can be adjusted in position, providing support and a basis for the material carrying structure on it. The upper surface of the support seat is equipped with a material seat that can be moved back and forth to place stacked packaging cardboard to be edge-cut. The front surface of the material seat is fixed with a horizontal material support plate, which can provide stable support for the stacked packaging cardboard. A cutting table is set on one side of the base and in front of the material support plate, serving as a dedicated work platform for cardboard edge-cutting operations. The cutting table is equipped with a cutting electric saw, which is specifically used to cut the sides of the stacked packaging cardboard conveyed to this area.

[0007] Furthermore, a support seat is mounted on the upper side of the base via a slide rail slider. A first drive motor is fixed on the base. The output shaft of the first drive motor is fixedly connected to a first screw. The first screw is mounted on the base via a bearing seat. A first sliding sleeve is fitted on the first screw. The first sliding sleeve is fixedly connected to the bottom of the support seat. The first drive motor drives the support seat to move on the base.

[0008] A support seat is mounted on the upper side of the base using a slide rail slider. The slide rail slider provides a suitable connection and fit between the support seat and the base for relative sliding. A first drive motor is fixedly mounted on the base. This motor serves as a power source to provide power support for the position movement of the support seat. The output shaft of the first drive motor is fixedly connected to a first screw. The first screw is mounted on the base with the help of a bearing seat. The bearing seat provides stable installation support and rotation guarantee for the smooth rotation of the first screw. A first sliding sleeve is sleeved on the first screw. The first sliding sleeve is fixedly connected to the bottom of the support seat. The operation of the first drive motor drives the first screw to rotate synchronously. Then, through the transmission action of the first sliding sleeve, the support seat is moved on the base to complete the position movement operation.

[0009] Furthermore, a material seat is mounted on the upper surface of the support base via a slide rail slider, and a second drive motor is mounted on the upper surface of the support base. The output shaft of the second drive motor is fixedly connected to a second screw. The second screw is mounted on the support base via a bearing seat, and a second sliding sleeve is fitted on the second screw. The second sliding sleeve is fixedly connected to the bottom of the material seat, and the second drive motor drives the material seat to move on the support base.

[0010] The upper surface of the support base is fitted with a material seat via a slide rail slider. The slide rail slider provides a stable sliding fit and guiding function for the movement of the material seat. A second drive motor is also installed on the upper surface of the support base. This motor serves as a power source to provide power support for the position adjustment of the material seat. The output shaft of the second drive motor is fixedly connected to the second screw. The second screw is mounted on the support base with the help of a bearing seat. The bearing seat provides a stable installation support and rotation guarantee for the smooth rotation of the second screw. A second sliding sleeve is fitted on the second screw and is fixedly connected to the bottom of the material seat. The operation of the second drive motor drives the second screw to rotate synchronously, and then through the transmission action of the second sliding sleeve, the material seat is moved on the support base to complete the position movement operation.

[0011] Furthermore, through slots are provided on both sides of the vertical plate of the material seat, and clamping plates that can move along the through slots are inserted into the through slots. Screw holes are provided on the side wall of the material seat, and tightening screws are screwed into the screw holes. The end of the tightening screws cooperates with the bearings installed in the clamping plates. Rotating the tightening screws causes the clamping plates to move along the through slots.

[0012] The material holder has through slots on both sides of its vertical plate. These slots provide a guide space for the movement of the clamping plate, which engages inside the slot and can move along it. The clamping plate is used to clamp and limit the stacked packaging cardboard placed on the material holder. The side wall of the material holder has screw holes, which provide a base for the screw-on installation of the tightening screw. The tightening screw is screwed into the screw hole, and its end engages with a bearing installed inside the clamping plate. The bearing prevents the clamping plate from rotating synchronously when the tightening screw rotates. By rotating the tightening screw, the clamping plate can be moved along the through slot to adjust its position, thereby adapting to the clamping and fixing requirements of stacked packaging cardboard of different specifications.

[0013] Furthermore, the lower edge of the saw blade of the cutting chainsaw is lower than the upper edge of the support plate.

[0014] The saw blade of the cutting chainsaw has its lower edge positioned below the upper edge of the support plate. This design ensures that when the cutting chainsaw performs a side cut on the stacked packaging cardboard placed on the support plate, it can completely sever the entire cardboard, achieving a thorough cutting effect and avoiding incomplete cutting or cardboard not being completely severed.

[0015] Furthermore, a through slot is provided on the vertical end plate of the support base, and the pressure plate can move downward after passing through the slot to press the upper edge of the packaging cardboard.

[0016] The vertical end plate of the support base has a through slot, which provides space for the pressure plate to pass through and move. The pressure plate passes through the slot and can move downward. This pressure plate can press and fix the upper edge of the packaging cardboard placed on the device, preventing the cardboard from shifting or warping during the cutting process and ensuring the stability of the cutting operation.

[0017] Furthermore, the pressure plate is fixed to the front edge of the lifting plate, the lifting plate is fixedly installed on the upper surface of the moving plate by the lifting cylinder, the two ends of the moving plate cooperate with the slide rail slider fixed on the upper surface of the support base, and the moving plate is fixedly connected to the push cylinder installed on the upper surface of the support base.

[0018] The pressure plate is fixedly positioned at the front edge of the lifting plate. The lifting plate is mounted and fixed to the upper surface of the moving plate via a lifting cylinder. The lifting cylinder provides power support for the up-and-down movement of the pressure plate, thereby enabling the pressure plate to press and release the packaging cardboard. Both ends of the moving plate cooperate with slide rails fixed to the upper surface of the support base. The slide rails provide stable guidance and sliding support for the movement of the moving plate. The moving plate is also fixedly connected to a push cylinder mounted on the upper surface of the support base. The push cylinder provides power for the position adjustment of the moving plate, enabling the pressure plate to move as a whole, thus adapting to the pressing requirements of different specifications of packaging cardboard and ensuring the accuracy of the pressing position.

[0019] By means of the above-described solution, the present invention has at least the following advantages:

[0020] 1. Automated adjustment of cutting position effectively improves cutting accuracy and processing efficiency. Through the transmission structure of motor, screw and slide rail slider, the support base and material base are moved precisely, replacing manual positioning and pushing, avoiding cardboard offset and warping, and eliminating manual adjustment steps, reducing labor intensity and improving processing efficiency.

[0021] 2. Equipped with a double fixing and limiting structure, it ensures that stacked cardboard is firmly fixed during cutting, greatly improving the processing yield. The clamping plate can be flexibly adjusted to clamp the cardboard on both sides, and the pressure plate can move precisely and press down on the upper edge of the cardboard. The double fixing prevents the cardboard from shaking and warping during cutting, ensuring flat cut edges and uniform dimensions.

[0022] 3. The cutting and supporting components are well-matched in position, ensuring cutting effect and extending equipment life. The lower edge of the cutting saw blade is lower than the upper edge of the supporting plate, which can completely cut the stacked cardboard, avoiding the problem of incomplete cutting, while preventing the saw blade from scratching the supporting plate and cardboard, reducing equipment wear and product damage.

[0023] 4. Significantly improves operational safety in edge cutting operations and eliminates safety hazards associated with manual operation. An automated structure transports the cardboard to the cutting area, replacing manual pushing and reducing contact between operators and cutting components, thus completely avoiding the safety risk of injury from the saw blade.

[0024] 5. The adjustable structures are highly flexible, and the equipment has excellent adaptability and versatility, meeting diverse processing needs. The clamps, pressure plates, support seats, and material seats are all flexibly adjustable, eliminating the need for frequent disassembly and assembly. This allows for quick adaptation to the processing of stacked cardboard of different lengths and widths, meeting the diverse production needs of the industry.

Detailed Implementation

[0028] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0029] See Figure 1 and Figure 2This stacked packaging cardboard edge-cutting device first places the stacked packaging cardboard to be edge-cut on the material seat 3 on the support base 2. The material support plate 4 on the front surface of the material seat 3 provides horizontal and stable support for the stacked cardboard. Then, the movable support base 2 installed on the base 1 on the ground is adjusted to a suitable lateral position according to the cutting size requirements. Next, the material seat 3, which can move back and forth on the support base 2, is moved so that the material seat 3 carries the stacked cardboard forward toward the cutting table 5 in front of the material support plate 4 on one side of the base 1, until the side of the cardboard to be cut is precisely in the cutting area of ​​the cutting electric saw 6 on the cutting table 5. Then, the cutting electric saw 6 is started to cut the side of the stacked cardboard. After the cutting is completed, the material seat 3 and the support base 2 are moved in the opposite direction so that the cut cardboard is away from the cutting table. Cutting saw 6, and finally remove the stacked cardboard with the edge cut. The base 1 provides a stable installation and operating foundation for the whole device. With the movable characteristics of the support base 2 and material seat 3, the relative cutting position of the stacked cardboard and cutting saw 6 can be flexibly and accurately adjusted. With the stable support of the material support plate 4, the cardboard remains flat and does not shift during movement and cutting. At the same time, the cutting table 5 provides a dedicated and stable working platform for cutting saw 6 and cutting operation. Cutting saw 6 can efficiently complete the side cutting of stacked cardboard. The whole process is convenient to operate, without complicated manual positioning and pushing. It can accurately control the cutting size, ensure the flatness and dimensional uniformity of the cut edge of stacked cardboard, and greatly improve the overall efficiency and processing quality of the edge cutting operation of stacked packaging cardboard.

[0030] See Figure 4According to the lateral position requirements of the edge cutting of stacked packaging cardboard, the first drive motor 7 fixed on the base 1 is started. The operation of the first drive motor 7 drives the first screw 8 fixedly connected to its output shaft to rotate synchronously. The first screw 8 achieves stable rotation on the base 1 with the support of the bearing seat. During its rotation, it drives the first sliding sleeve 9 sleeved on it to make linear displacement along the screw. Since the first sliding sleeve 9 is fixedly connected to the bottom of the support seat 2, and the upper side of the base 1 is assembled with the support seat 2 through the slide rail slider, the support seat 2 moves smoothly on the base 1 with the movement of the first sliding sleeve 9 to complete the lateral position adjustment. After the support seat 2 moves to the preset cutting adaptation position, the first drive motor 7 is turned off to keep the support seat 2 in a fixed position, providing precise position support for subsequent cardboard edge cutting operations. This workflow With the first drive motor 7 providing a continuous and stable power source, the rotational motion of the motor is converted into the linear movement of the support seat 2 through the transmission cooperation between the first screw 8 and the first sliding sleeve 9. In conjunction with the slide rail slider between the base 1 and the support seat 2, the smoothness and stability of the support seat 2's movement on the base 1 can be effectively guaranteed, avoiding jamming or deviation. The bearing seat's support for the first screw 8 ensures the smooth operation of the transmission structure and reduces mechanical failures of the equipment. The overall system realizes the automated adjustment of the support seat 2's position, replacing the traditional manual adjustment method, significantly improving the accuracy of the support seat 2's position adjustment, effectively avoiding positional deviations caused by manual adjustment, laying the foundation for the subsequent precise cutting of cardboard, and also improving the efficiency of position adjustment and reducing the labor intensity of operators.

[0031] See Figure 5The second drive motor 10, installed on the upper surface of the support base 2, is started. The second drive motor 10 drives the second screw 11, which is fixedly connected to its output shaft, to rotate synchronously. The second screw 11 is stably rotated on the support base 2 with the support of the bearing housing. During its rotation, it drives the second sliding sleeve 12, which is sleeved on it, to make linear displacement along the screw. Since the second sliding sleeve 12 is fixedly connected to the bottom of the material seat 3, and the upper surface of the support base 2 is assembled with the material seat 3 via a slide rail slider, the material seat 3 moves smoothly on the support base 2 with the movement of the second sliding sleeve 12, completing the front-to-back position adjustment. After the material seat 3 moves to the preset position that allows the cardboard to accurately align with the cutting area, the second drive motor 10 is turned off, allowing the material seat 3 to remain in a fixed position, providing precise positioning for subsequent cardboard cutting and feeding. This workflow uses the second drive motor 10 to provide a stable and continuous power source for the position adjustment of the material seat 3. The transmission cooperation between the second screw 11 and the second sliding sleeve 12 converts the rotational motion of the motor into the linear movement of the material seat 3. Combined with the slide rail slider between the support seat 2 and the material seat 3, this effectively ensures the smoothness and stability of the material seat 3's back-and-forth movement on the support seat 2, preventing jamming and offset. The bearing housing's support for the second screw 11 ensures the smooth operation of the overall transmission structure, reducing mechanical wear and equipment failure. This achieves automated and precise adjustment of the material seat 3's position, replacing the traditional manual pushing adjustment method. This significantly improves the accuracy of the material seat 3's back-and-forth position adjustment, effectively avoiding positional deviations caused by manual adjustment. It allows the stacked cardboard on the material seat 3 to precisely align with the cutting area, laying a crucial foundation for precise edge cutting of the cardboard. It also improves the efficiency of the material seat 3's position adjustment, eliminating the need for manual pushing of cardboard and adjustment of the material seat, greatly reducing the labor intensity of operators.

[0032] See Figure 1 and Figure 6After placing the stacked packaging cardboard on the material holder 3, according to the width specifications of the cardboard, rotate the tightening screw 14 screwed into the screw hole on the side wall of the material holder 3. Because the end of the tightening screw 14 is engaged with the bearing installed in the clamping plate 13, the rotation will not drive the clamping plate 13 to rotate synchronously, but will only push the clamping plate 13 to move smoothly along the through grooves on both sides of the vertical plate of the material holder 3 until the clamping plates 13 on both sides abut against the side wall of the stacked cardboard and achieve a firm clamping. After the cardboard cutting operation is completed, rotate the tightening screw 14 in the opposite direction, which will drive the clamping plate 13 to move back along the through groove, releasing the cut stacked cardboard, completing the entire cardboard clamping and releasing operation. This workflow uses the through groove to provide precise guidance for the movement of the clamping plate 13, ensuring the smoothness and positional accuracy of the clamping plate 13 during the movement process. The design of the clamping screw 14 effectively prevents the clamping plate 13 from rotating when the clamping screw 14 rotates, ensuring that the clamping plate 13 always maintains a stable clamping state. The screw engagement between the clamping screw 14 and the screw hole allows for flexible adjustment of the position of the clamping plate 13, which can adapt to stacked packaging cardboard of different widths. Different cardboard can be clamped and fixed without changing parts, demonstrating strong adaptability. Furthermore, the firm clamping of both sides of the cardboard by the clamping plate 13 effectively prevents the cardboard from shifting or shaking during cutting and movement, laying the foundation for subsequent precise cutting. The overall operation is simple and convenient, requiring no additional power equipment. Clamping and loosening operations can be completed manually by rotating the screw, making the operation threshold low. At the same time, the tight fit of each structure ensures a stable clamping effect, effectively improving the accuracy and yield of cardboard cutting.

[0033] See Figure 2First, the stacked cardboard to be cut is placed on the support plate 4 to form a stable support. Then, the stacked cardboard on the support plate 4 is conveyed to the cutting area of ​​the cutting electric saw 6. After the cutting electric saw 6 is started, its saw blade cuts the side of the stacked cardboard as the equipment moves. Because the lower edge of the saw blade of the cutting electric saw 6 is lower than the upper edge of the support plate 4, the saw blade can fully act on the stacked cardboard on the support plate 4, completing the full-thickness cutting operation from the side of the cardboard until the stacked cardboard is completely cut off, completing the entire edge cutting process. The advantage of this structural design is that this position ensures that the cutting electric saw 6 can completely cut the stacked cardboard on the support plate 4, effectively avoiding incomplete cutting and incomplete cardboard cutting. In the cutting process, the edge cutting operation is completed in one go. At the same time, the design of the lower edge of the saw blade of the cutting electric saw 6 being lower than the upper edge of the support plate 4 ensures that the saw blade only acts on the cardboard during the cutting process and will not scratch the upper edge of the support plate 4. This reduces the wear of the saw blade of the cutting electric saw 6, extends its service life, and prevents the support plate 4 from being scratched and affecting the flatness of the cardboard. It also prevents the cardboard surface from being damaged by the saw blade scratching, ensuring the edge flatness and product integrity of the stacked cardboard after cutting, and improving the overall edge cutting quality. In addition, this fixed position design eliminates the need for manual adjustment of the relative position of the saw blade and the support plate, simplifying the cutting operation steps and improving the efficiency of the edge cutting operation.

[0034] See Figure 7 After placing the packaging cardboard to be cut in place, operate the pressure plate 16, which passes through the through slot 15 on the vertical end plate of the support base 2, to move the pressure plate 16 downwards along the slot 15 until the pressure plate 16 is tightly pressed against the upper edge of the packaging cardboard. Then, carry out the edge cutting operation of the cardboard. After the cutting operation is completed, operate the pressure plate 16 upwards to release the pressing limit on the upper edge of the packaging cardboard, and the cut cardboard can be easily removed. This completes the entire process of fixing and releasing the pressure plate. The through slot 15 on the support base 2 provides a dedicated space for the pressure plate 16 to pass through and guide its vertical movement, ensuring the smoothness of the pressure plate 16 during movement. The accurate positioning prevents the pressure plate 16 from shifting or jamming during movement. The design of the pressure plate 16 moving downwards to press the upper edge of the packaging cardboard effectively prevents the cardboard from warping or shifting during the cutting process, keeping the cardboard flat and stable. This provides a reliable positional guarantee for precise edge cutting. At the same time, the up-and-down movement of the pressure plate 16 can quickly press and release the cardboard, closely matching the overall rhythm of the cutting operation and improving the overall efficiency of the edge cutting operation. Furthermore, the pressing structure is integrated with the support base 2, with a compact and reasonable structural design that eliminates the need for additional installation structures, making full use of the existing space of the device and making the overall layout more regular.

[0035] According to the specifications of the packaging cardboard and the required pressing position, the push cylinder 20 installed on the upper surface of the support base 2 is activated. The push cylinder 20 drives the movable plate 19 fixedly connected to it to move. The two ends of the movable plate 19 cooperate with the slide rail sliders fixed on the upper surface of the support base 2 to ensure that the movable plate 19 moves smoothly and accurately along the upper surface of the support base 2. This, in turn, drives the lifting plate 17 installed on the upper surface of the movable plate 19 via the lifting cylinder 18, and the pressure plate 16 fixed to the front edge of the lifting plate 17 to move horizontally as a whole until the pressure plate 16 is adjusted. Once the cardboard reaches the preset pressing position at the top edge, the lifting cylinder 18 is activated. The lifting cylinder 18 drives the lifting plate 17 downwards, simultaneously moving the pressure plate 16 downwards until it is tightly pressed against the top edge of the cardboard. After the cardboard cutting operation is completed, the lifting cylinder 18 is activated again to move the lifting plate 17 and pressure plate 16 upwards, releasing the pressing limit on the top edge of the cardboard. Then, the pushing cylinder 20 is activated to move the moving plate 19 and the lifting cylinder 18, lifting plate 17, and pressure plate 16 back to their initial positions, completing the entire process. The pressure plate position adjustment and pressing / releasing operation process utilizes the push cylinder 20 and the slide rail slider to automate the horizontal movement of the moving plate 19, allowing the pressure plate 16 to flexibly adjust its horizontal pressing position. This precisely adapts to the pressing needs of packaging cardboard of different lengths and widths. The lifting cylinder 18 provides stable power support for the up-and-down movement of the pressure plate 16, automating the pressing and releasing of the cardboard and replacing manual pressing methods. This significantly improves operational efficiency and reduces the labor intensity of operators. The pressure plate 16 is fixed to the front edge of the lifting plate 17, and the connections between all components are firm, ensuring stable transmission of pressing force and uniformly pressing the upper edge of the cardboard. This effectively prevents warping and offset of the cardboard during the cutting process, providing a reliable guarantee for accurate cutting of the cardboard. At the same time, the cooperation between the moving plate 19 and the slide rail slider ensures a smooth and uninterrupted overall movement. The assembly layout of each component and the support base 2 is compact and reasonable. The automated position adjustment and pressing action can precisely match the overall rhythm of the cutting operation, further improving the automation level and overall processing accuracy of the stacked packaging cardboard edge cutting operation.
