Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, specifically a multi-directional compression packaging machine. Background Technology

[0002] In the field of multi-directional compression packaging machines, to improve material compression efficiency and packaging tightness, compression cylinders are usually installed on the top, sides, and other positions of the machine frame to achieve rapid material compression through multi-directional extrusion. However, in existing technologies, the top compression cylinders of multi-directional compression packaging machines are mostly installed on the top of the frame by direct welding or single bolt fixing, lacking a unified installation benchmark and flexible adjustment structure. When it is necessary to adjust the number, installation position, or compression stroke of the top compression cylinders according to the size, height, or compression requirements of the material to be compressed, it is necessary to disassemble the fixed connecting parts on the top of the frame, and even modify the frame structure. This is cumbersome and inefficient, and it is difficult to guarantee the positional accuracy and synchronous compression effect after multiple top compression cylinders are installed. This results in poor adaptability of the equipment to different specifications of materials and the problem of inconvenient adjustment of the top compression cylinders.

[0003] Chinese Patent CN222988556U discloses a compression packaging machine. It includes a support frame, a base plate, compression plates, and drive cylinders. The compression plates are mounted on the support frame, and drive cylinders are mounted on the compression plates. The compression plates include front and rear compression plates, left and right compression plates, and an upper compression plate. The front and rear compression plates rotate along a pivot at the bottom of the base plate under the drive cylinders. The left and right compression plates are mounted on both sides of the base plate, and the upper compression plate is mounted above the support frame. In practical application, this invention uses drive cylinders to drive the compression plates to compress workpieces on the base plate, resulting in higher compression efficiency. The stability of the compression plates is ensured by setting drive cylinders on each compression plate. However, in the above-mentioned device, the drive cylinders for the compression plates are directly mounted on a fixed plate above the support frame, making it impossible to flexibly adjust the number, installation position, and compression stroke of the drive cylinders according to material specifications. Therefore, those skilled in the art urgently need to solve the above-mentioned technical problems. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned prior art by adjusting the position and number of compression cylinders on the top of the frame through mounting holes, thereby improving the flexibility of the compression packaging machine.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A multi-directional compression packaging machine includes a frame, a compression plate, a compression cylinder, a displacement cylinder, and a limit plate;

[0007] The compression cylinders are installed at the rear end, top, and left and right sides of the frame. The piston rod end of each compression cylinder is fixedly connected to the compression plate for squeezing the material to be compressed. At least two displacement cylinders are provided at the front end of the frame. The piston rod end of each displacement cylinder is fixedly connected to the limiting plate, and the displacement cylinder drives the limiting plate to move up and down along the vertical direction of the frame to adjust the limiting height.

[0008] By adopting the above technical solution, compression cylinders are installed at the rear, top, and left and right sides of the frame, and the piston rods of each compression cylinder are connected to the compression plate. This allows for simultaneous or stepwise compression of materials from multiple directions, including front and back, left and right, and up and down, significantly improving material compression efficiency and packaging tightness. At the same time, the displacement cylinder at the front of the frame drives the limit plate to move vertically, which can flexibly adjust the limit height according to the height of the material to be compressed, preventing the material from shifting forward during compression, enhancing the equipment's adaptability to materials of different specifications, and improving packaging stability.

[0009] Furthermore, the two displacement cylinders are symmetrically distributed on the left and right sides of the front end of the frame and are fixed to the outer side wall of the frame by bolts; the piston rod ends of the displacement cylinders are fixed to the left and right sides of the limiting plate; the inner side wall of the front end of the frame is also provided with vertically extending slide rails on both sides of the limiting plate, and the left and right sides of the limiting plate are provided with rollers that cooperate with the slide rails, and are slidably mounted on the slide rails by the rollers.

[0010] By adopting the above technical solution, two displacement cylinders are symmetrically distributed on the left and right sides of the front end of the frame and fixed with bolts. With the connection between the piston rod and the two sides of the limiting plate, the limiting plate can be subjected to uniform force when moving vertically, avoiding unilateral tilting. The sliding cooperation between the slide rail on the inner side of the frame and the roller of the limiting plate can provide a stable guiding effect for the limiting plate, reduce the frictional resistance during the movement, ensure the smoothness of the limiting plate adjustment, improve the adjustment accuracy of the limiting height, and extend the service life of the displacement mechanism.

[0011] Furthermore, two of the aforementioned compression cylinders are installed on the left and right sides of the frame, i.e., two on the left and two on the right, for a total of four side compression cylinders; each side compression cylinder is fixed to the outer wall of the frame via an L-shaped support frame, with the horizontal section of the support frame connected to the frame and the vertical section connected to the cylinder body of the compression cylinder; the piston rod of the side compression cylinder is connected to the corresponding compression plate via a connector, the connector being a disc-shaped structure and fixed to the side of the compression plate away from the material to be compressed by bolts.

[0012] By adopting the above technical solution, two compression cylinders are installed on each of the left and right sides of the frame (a total of four side compression cylinders), which can provide greater extrusion force from the left and right directions to meet the compression needs of materials with larger volume or looser texture. The L-shaped support frame is connected to the frame through the horizontal section and to the cylinder body through the vertical section, which enhances the installation stability of the side compression cylinders and prevents the cylinders from shaking due to excessive force during compression. The disc-shaped connector increases the contact area between the piston rod and the compression plate, making the compression plate more evenly stressed during lateral compression, reducing local deformation, and further ensuring the compactness of the material during lateral compression.

[0013] Furthermore, at least one horizontally arranged compression cylinder is installed at the rear end of the frame, and the piston rod end of the compression cylinder is fixedly connected to the compression plate, and the extrusion surface of the compression plate is parallel to the plate surface of the limiting plate.

[0014] By adopting the above technical solution, at least one horizontally arranged compression cylinder is installed at the rear end of the frame. The compression plate extrusion surface connected to its piston rod is parallel to the front limit plate surface, which can form opposing extrusion in the front-rear direction with the front limit plate, so that the material is subjected to uniform force in the front-rear direction, avoiding material deviation or uneven compression due to unilateral extrusion. The horizontally arranged cylinder structure simplifies the transmission path of the rear compression. The compression stroke adjustment is directly realized by the extension and retraction of the piston rod, which is convenient to operate and improves the control accuracy of compression in the front-rear direction.

[0015] Furthermore, a horizontally mounted mounting plate is fixed to the top of the frame by bolts, and a compression cylinder at the top of the frame is mounted on the upper surface of the mounting plate; at least two compression cylinders are provided at the top of the frame, and the piston rod of the compression cylinder at the top of the frame extends vertically downward, with its end fixedly connected to the horizontally mounted compression plate.

[0016] By adopting the above technical solution, the top of the frame is fixed with a horizontal mounting plate by bolts, which provides a unified installation benchmark for the top compression cylinders, facilitates the positioning and installation of multiple cylinders, and ensures the positional accuracy between each cylinder; the setting of at least two top compression cylinders can provide sufficient extrusion force from above to adapt to the compression requirements of materials of different heights; the piston rod is vertically connected to the compression plate, so that the top compression force acts directly on the material, reducing force loss and improving the top compression efficiency and the flatness of the material surface.

[0017] Furthermore, the mounting plate has at least three mounting holes, and the mounting plate also has positioning screw holes corresponding to the mounting positions of each compression cylinder; the cylinder body of the compression cylinder at the top of the frame is fixed to the mounting plate by bolts and positioning screw holes, and the piston rod of the compression cylinder at the top of the frame passes through the corresponding mounting hole and is fixedly connected to the compression plate.

[0018] By adopting the above technical solution, the at least three mounting holes and positioning screw holes on the mounting plate allow for flexible adjustment of the number and installation position of the top compression cylinders according to the size of the material to be compressed and the compression requirements, without the need to disassemble the frame or modify the structure, making operation convenient. The structure in which the cylinder body is fixed to the positioning screw holes with bolts and the piston rod passes through the mounting holes to connect to the compression plate not only ensures the stability of the cylinder installation, but also facilitates quick disassembly, replacement or adjustment of the cylinder position, significantly improving the equipment's adaptability to materials of different specifications and adjustment efficiency, and solving the problem of traditional top cylinders being difficult to adjust.

[0019] Furthermore, casters are bolted to the bottom of the frame.

[0020] By adopting the above technical solution, casters are bolted to the bottom of the frame, enabling the equipment to move flexibly according to the layout of the production site, adapt to different work position requirements, and reduce the intensity of manual handling; the bolt connection method facilitates the disassembly and maintenance of the casters, ensures the long-term reliability of the equipment's movement function, and improves the equipment's flexibility and site adaptability.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model achieves synchronous or stepwise compression of materials in multiple directions (front-back, left-right, up-down) by setting compression cylinders at the rear end, top, and left and right sides of the frame and connecting them with compression plates, which significantly improves material compression efficiency and packaging tightness.

[0023] 2. This utility model, by installing a mounting plate with mounting holes and positioning screw holes on the top of the frame, allows for flexible adjustment of the number and installation position of the top compression cylinders, enabling adaptation to materials of different specifications without modifying the frame, thus solving the problem of inconvenient adjustment of traditional top cylinders;

[0024] 3. This utility model uses displacement cylinders symmetrically distributed at the front end of the frame to drive the limiting plate, and with the help of slide rails and rollers for guidance, it can achieve stable and smooth vertical movement of the limiting plate, accurately adjust the limiting height, avoid material compression and deviation, and improve packaging stability;

[0025] 4. This utility model uses casters installed at the bottom of the frame to allow the equipment to move flexibly to adapt to different working positions, reducing the handling intensity. The bolt connection makes it easy to disassemble and maintain the casters, ensuring long-term reliable mobility. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0032] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As can be seen, this utility model discloses a multi-directional compression packaging machine. The device uses a frame 1 as the overall support base, and universal wheels 12 are installed at the bottom of the frame 1 by bolts 6 to realize the compression packaging of materials. The front end of the frame 1 is a material limit adjustment area, and two displacement cylinders 4 are symmetrically distributed on the left and right sides. The displacement cylinders 4 are fixed to the outer wall of the frame 1 by bolts 6. The piston rod ends extend horizontally inward and are fixed to the left and right sides of the limit plate 5, forming a symmetrical drive for the limit plate 5. In order to ensure the stability of the movement of the limit plate 5, the inner side wall of the front end of the frame 1 is provided with vertically extending slide rails 7 corresponding to the two sides of the limit plate 5. Rollers 8 matching the slide rails 7 are installed on the left and right sides of the limit plate 5. The rollers 8 can roll along the slide rails 7, so that the limit plate 5 can move smoothly in the vertical direction under the drive of the displacement cylinders 4, realizing flexible adjustment of the limit height. The left and right sides of the frame 1 are lateral compression execution areas, with two compression cylinders 3 installed on each side, for a total of four lateral compression cylinders. These compression cylinders 3 are fixed to the outer side wall of the frame 1 by L-shaped support frames 9. The horizontal section of the support frame 9 is connected to the side wall of the frame 1 by bolts 6, and the vertical section is fixed to the cylinder body of the compression cylinder 3, forming a stable lateral support. The piston rod of the lateral compression cylinder 3 extends horizontally inward, and its end is connected to the compression plate 2 by a disc-shaped connector 10. The connector 10 is fixed to the side of the compression plate 2 away from the material to be compressed by bolts 6, ensuring that the driving force of the piston rod is evenly transmitted to the compression plate 2, realizing the compression of the material in the left and right directions. The rear end of the frame 1 is a rearward compression execution area, where at least one horizontally arranged compression cylinder 3 is installed. The cylinder body of the compression cylinder 3 is fixed to the rear side wall of the frame 1, and the piston rod extends horizontally forward and is fixedly connected to the end of the compression plate 2. The extrusion surface of the compression plate 2 is parallel to the plate surface of the front limiting plate 5 so as to cooperate with the limiting plate 5 to form opposing extrusion in the front and rear directions, ensuring that the material is subjected to uniform force in the front and rear directions. The top of the frame 1 is the upward compression execution area, where a horizontally mounted mounting plate 11 is fixed with bolts 6. The mounting plate 11 has at least three mounting holes (111) and corresponding positioning screw holes for each compression cylinder 3. At least two of the top compression cylinders 3 are fixed to the upper surface of the mounting plate 11 with bolts 6 and positioning screw holes. Their piston rods pass vertically downwards through the corresponding mounting holes 111 on the mounting plate 11 and are fixedly connected to the horizontally mounted compression plate 2. The piston rods extend and retract to compress the top of the material. The mounting holes 111 and positioning screw holes on the mounting plate 11 are designed to allow flexible adjustment of the number and installation position of the top compression cylinders 3 to accommodate materials of different specifications. Each compression plate 2, as a direct compression component, is installed on the left and right sides, rear end, and top of the frame 1, respectively, at the piston rod ends of the compression cylinders 3, forming a multi-directional compression structure around the material. Together with the adjustable front-end limiting plate 5, this achieves multi-directional synchronous or stepwise compression of the material.

[0034] In one embodiment, refer to Figure 2As can be seen, the compression cylinder 3 at the top of the frame can be flexibly adjusted and compress the material through the mounting plate 11. The top of the frame 1 is fixed with a horizontally set mounting plate 11 by bolts 6. The mounting plate 11 serves as the mounting base for the top compression cylinder 3. It has at least three mounting holes 111 and positioning screw holes corresponding to the mounting positions of each compression cylinder 3. During adjustment, different positioning screw holes on the mounting plate 11 can be selected according to the size of the material to be compressed and the compression requirements. The cylinder body of the compression cylinder 3 is fixed to the upper surface of the mounting plate 11 by bolts 6. At the same time, the piston rod of the compression cylinder 3 passes through the corresponding mounting hole 111 on the mounting plate 11. This allows the number of top compression cylinders 3 to be adjusted to at least two and their mounting positions to be adjusted without disassembling the frame 1 or modifying the overall structure. The operation is convenient and highly adaptable. When compressing materials, the compression cylinder 3 at the top of the frame is activated, and its piston rod extends vertically downward, passing through the mounting hole 111 of the mounting plate 11. The horizontally fixed compression plate 2 at the end moves downward synchronously under the drive of the piston rod. Since at least two compression cylinders 3 are evenly distributed on the mounting plate 11, downward extrusion force can be applied from multiple points above the material, ensuring that the compression plate 2 is subjected to uniform force and presses down smoothly, directly acting on the top of the material to achieve vertical compression of the material, making the upper surface of the material flat and compact. Together with the compression components in other directions of the frame 1, it completes multi-directional compression packaging.

[0035] In one embodiment, refer to Figure 3As can be seen, the compression cylinder 3 at the rear end of the frame works in conjunction with the compression plate 2 and the front limiting plate 5 through a horizontally set installation method to achieve precise compression of the material in the front-back direction. The specific process is as follows: The rear side wall of the frame 1 serves as the installation base, and at least one horizontally set compression cylinder 3 is fixed thereon. Its cylinder body is rigidly connected to the rear side wall of the frame 1 by bolts 6 or welding to ensure that the cylinder body does not shake during the compression process. The piston rod extends forward in the horizontal direction, and its end is directly fixed to the side of the compression plate 2 away from the material to be compressed, usually by bolts 6 or flange structure. The extrusion surface of the compression plate 2, that is, the side of the plate facing the material, is processed into a flat surface and is strictly parallel to the plate surface of the front limiting plate 5 of the frame 1, providing a structural basis for the front-back opposing extrusion. When the material to be compressed is placed in the compression area inside the frame 1, the front limiting plate 5 is adjusted to a limiting position matching the height of the material by the displacement cylinder 4. The surface of the limiting plate 5 is perpendicular to the ground, forming a blocking surface at the front end of the material. At this time, the rear compression cylinder 3 receives the compression signal, and the air pressure inside the cylinder drives the piston rod to extend forward, causing the compression plate 2 to move forward synchronously in the horizontal direction. As the piston rod continues to extend, the extrusion surface of the compression plate 2 gradually approaches the rear end surface of the material, applying a compressive force to the rear end of the material. Since the surfaces of the compression plate 2 and the limiting plate 5 are parallel and are located on the front and rear sides of the material respectively, the material is tightly clamped between the compression plate 2 and the limiting plate 5 under the action of the compressive force. The front end is blocked by the limiting plate 5 and cannot move forward, while the rear end is continuously pushed by the compression plate 2, thereby achieving opposing compression in the front and rear directions. During this process, the piston rod of the compression cylinder 3 controls the compression rate by extending and retracting at a uniform speed, avoiding material breakage or displacement due to excessive impact force; the large-area extrusion surface of the compression plate 2 ensures that the rear end of the material is subjected to uniform force, and with the stable support of the limiting plate 5, it effectively prevents the material from shifting forward or backward or sinking locally during the compression process, ultimately making the material form a compact and flat compressed shape in the forward and backward direction, laying the foundation for the subsequent compression processes in the left, right and up and down directions.

[0036] In one embodiment, refer to Figure 4As can be seen, the compression cylinders 3 on both sides of the frame work together with the transmission components through a symmetrically distributed installation structure to achieve uniform compression of the material in the left and right directions. The specific process is as follows: The left and right sides of the frame 1 are the lateral compression execution areas, with two compression cylinders 3 installed on each side, for a total of four side compression cylinders, forming a symmetrical lateral extrusion layout. These compression cylinders 3 are fixed to the outer wall of the frame 1 by L-shaped support frames 9. The horizontal section of the support frame 9 is rigidly connected to the side wall of the frame 1 by bolts 6, while the vertical section is fixed to the cylinder body of the compression cylinder 3. The stability of the L-shaped structure firmly supports the cylinder 3 on the outside of the frame 1, preventing the cylinder body from shaking during compression. The piston rod of the side compression cylinder 3 extends horizontally inward, and its end is connected to the compression plate 2 on the corresponding side by a disc-shaped connector 10. The connector 10 is fixed to the side of the compression plate 2 away from the material to be compressed by bolts 6. This disc-shaped structure can increase the contact area between the piston rod and the compression plate 2, ensuring that the driving force is evenly transmitted to the entire compression plate 2, and preventing local stress concentration from causing deformation of the compression plate 2. When the material to be compressed is placed inside the frame 1, after the front limiting plate 5 and the rear compression plate 2 complete the front-to-back positioning, the compression cylinders 3 on both sides start synchronously. The air pressure inside the cylinder drives the piston rod to extend horizontally inward, and drives the compression plate 2 to move towards the material through the connecting piece 10. Since the two compression cylinders 3 on each side are symmetrically distributed, and each compression plate 2 is connected to the piston rod through two connecting pieces 10, the compression plate 2 remains parallel to the side of the material during the movement, avoiding tilting. As the piston rod continues to extend, the compression plates 2 on both sides gradually approach the left and right surfaces of the material and apply squeezing force, so that the material is tightly compressed in the left and right directions. With the cooperation of the compression components in other directions of the frame 1, the material is finally tightly packaged in multiple directions.

[0037] Working principle: With the frame 1 as the overall support base, the adjustable front limit plate 5 works in conjunction with the compression cylinders 3 at the rear, left and right sides and top to achieve multi-directional compression. First, the displacement cylinder 4 drives the limit plate 5 to move up and down along the slide rail 7, adjusting the limit height according to the height of the material to be compressed, forming a front-end block. Then, the horizontally set compression cylinder 3 at the rear drives the corresponding compression plate 2 to extend forward, cooperating with the limit plate 5 to achieve front-to-back compression. At the same time, two symmetrically distributed compression cylinders 3 on each of the left and right sides are fixed by the L-shaped support frame 9, and the piston rod drives the compression plate 2 to move horizontally inward through the disc-shaped connector 10 to complete the left and right compression. The top compression cylinder 3 is adjusted in position through the positioning screw holes on the mounting plate 11, and the piston rod pushes the compression plate 2 vertically downward to achieve top compression. Each compression plate 2 forms a multi-directional compression structure around the material, which can complete the material compression simultaneously or in steps.

[0038] To address the issue of the single compression direction in traditional packaging machines, a layout of multiple sets of compression cylinders 3 at the rear, left and right sides, and top is adopted. These, along with the front limiting plate 5, form a six-directional front-end limiting and active compression system, achieving multi-directional force application. To address the issue of uneven compression, the cylinders 3 on the left and right sides are symmetrically distributed, and each compression plate 2 is connected to the piston rod via multiple connectors 10. For example, the side compression plate 2 is connected to two cylinders 3 via two connectors 10, ensuring uniform force on the compression surface and avoiding local depressions. To address the issue of poor adaptability, the positioning screw holes and mounting holes (111) of the top mounting plate 11 are designed to allow adjustment of the number and position of the top cylinders 3, and the displacement cylinder 4 adjusts the height of the limiting plate 5 to adapt to different material specifications. To address the issue of unstable limiting, the limiting plate 5 is coordinated with the rollers 8 and the slide rails 7 to ensure smooth lifting and improve compression accuracy, thereby effectively solving the technical pain points of poor compression effect, low adaptability, and complex operation of traditional packaging machines.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solution of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
