Description

Technical Field

[0001] This invention relates to the field of sponge processing equipment technology, specifically to a high-stability sponge multi-stage compression automatic bundling and packaging device. Background Technology

[0002] Sponges are widely used in many fields. Due to their soft texture and large volume, they are expensive to store and transport in a loose state and are easily damaged. Compression and packaging are necessary preliminary steps.

[0003] Currently, the industry largely adopts a traditional equipment plus manual assistance model, which has many drawbacks: poor compression stability, inaccurate positioning, and easy displacement and deformation of the sponge; manual unloading is required, which is labor-intensive, inefficient, and prone to damage; it can only compress a single component, resulting in limited volume reduction and weak bundling; the degree of automation is low, and process switching requires manual intervention, which cannot meet the needs of large-scale production; moving parts lack proper support, leading to high failure rates and short lifespans. With the development of the sponge industry, the market demands higher levels of automation, precision, efficiency, and stability from equipment, which traditional equipment can no longer meet. Therefore, a high-stability multi-stage compression automatic bundling and packaging device for sponges is proposed. Summary of the Invention

[0024] Example: Refer to Figures 1-8 A high-stability sponge multi-stage compression automatic bundling and packaging device includes a compressor 1. The compressor 1 includes a frame 100, a pressure plate 101, a platform 109 and a base plate 110. The device is characterized in that: a guide positioning device 2 is provided at the bottom of the compressor 1, automatic unloading devices 3 are provided on both sides of the compressor 1, a stacked compression and packaging device 4 is provided on one side of the compressor 1, and a conveyor belt 5 is provided between the compressor 1 and the stacked compression and packaging device 4.

One end of the first rotating shaft 302 and one end of the second rotating shaft 303 are rotatably installed in the limiting boxes 305 on both sides, respectively. The first limiting rod 304 is rotatably installed in the limiting box 305 on both sides. Inside the housing 305, the mounting box 308 is slidably mounted on the first rotating shaft 302, the second rotating shaft 303, and the first limiting rod 304. The second motor 309 is fixedly mounted on one side of the mounting box 308. The first lead screw 310 and the second limiting rod 311 are rotatably mounted inside the mounting box 308. The lever 312 is slidably mounted on the first lead screw 310 and the second limiting rod 311. Its function is as follows: the first motor 300 provides power, which drives the first rotating shaft 302 and the second rotating shaft 303 to rotate after the force is reversed by the T-shaped right-angle box 301. This drives the mounting box 308 to slide along the first rotating shaft 302, the second rotating shaft 303, and the first limiting rod 304. The second motor 309 drives the first lead screw 310 to rotate, which drives the lever 312 to slide along the first lead screw 310 and the second limiting rod 311. This realizes the automatic unloading and pushing of the compressed sponge, ensuring smooth and accurate unloading.

[0025] A first hydraulic cylinder 102 is fixedly installed on the top of the frame 100, and a first mounting plate 103 is fixedly installed on one side of the pressure plate 101. An ironing sealer 104 is provided on the first mounting plate 103, and a metal pad 108 is fixedly installed on the table 109. The piston rod of the first hydraulic cylinder 102 passes through the frame 100 and is fixedly connected to the upper surface of the pressure plate 101. There are four first hydraulic cylinders 102, which are distributed at the four corners of the top surface of the frame 100. The first hydraulic cylinders 102 are connected to the hydraulic system through a hydraulic synchronous motor. Their functions are: the frame 100 provides overall installation support for the compressor 1; the four first hydraulic cylinders 102 are controlled by the hydraulic synchronous motor to achieve synchronous extension and retraction, driving the pressure plate 101 to move up and down, and performing primary compression on the sponge on the table 109; the metal pad 108 provides support for the sponge compression; and the ironing sealer 104 is used to iron and seal the compressed sponge packing tape to ensure that the packing is secure.

[0026] A first electric cylinder push rod 105 and a first bushing 106 are fixedly installed on the first mounting plate 103. The first bushing 106 is installed on both sides of the first electric cylinder push rod 105. A first sliding shaft 107 is fixedly installed on the ironing sealer 104. The first sliding shaft 107 is slidably installed inside the first bushing 106. The movable end of the first electric cylinder push rod 105 passes through the first mounting plate 103 and is fixedly connected to the ironing sealer 104. Its function is: the first mounting plate 103 provides an installation carrier for ironing and sealing related components; the first electric cylinder push rod 105 provides power to drive the ironing sealer 104 to slide smoothly along the first bushing 106 and the first sliding shaft 107, adjust the position of the ironing sealer 104, adapt to the packaging and sealing needs of sponges of different sizes, and ensure that the sealing position is accurate and flat.

[0027] The first rotating shaft 302 and the second rotating shaft 303 have threads on one end inside the mounting box 308. The threads on the first rotating shaft 302 and the second rotating shaft 303 have opposite directions of rotation, but the same pitch and thread angle. The mounting boxes 308 on both sides are threadedly connected to the first rotating shaft 302 and the second rotating shaft 303, respectively. Their function is to use the reverse thread engagement of the first rotating shaft 302 and the second rotating shaft 303 to enable the mounting boxes 308 on both sides to slide synchronously in opposite directions when the rotating shaft rotates, thereby driving the lever 312 to adjust its position synchronously. This ensures that the force is evenly distributed when the sponge is ejected, avoids sponge displacement and damage, and improves ejection stability.

[0028] One end of the first lead screw 310 is rotatably installed inside the inner wall of the mounting box 308, and the other end passes through the side wall of the mounting box 308 and is fixedly connected to the output shaft of the second motor 309. The lever 312 is threadedly connected to the first lead screw 310. Its function is: the second motor 309 drives the first lead screw 310 to rotate, and drives the lever 312 to slide up and down along the first lead screw 310 and the second limit rod 311 through thread transmission, so as to adjust the height of the lever 312 to adapt to sponges with different compression thicknesses, ensure that the lever 312 can accurately contact the sponge and complete the material ejection and pushing, and improve the adaptability of the device.

[0029] A pair of fixed seats 306 are fixedly installed at the bottom of the base plate 110. Bearings 307 are fixedly installed inside the fixed seats 306. The fixed seats 306 are located on both sides of the output end of the T-shaped right angle box 301. The central axis of the bearing 307 is on the same straight line as the axis of the first rotating shaft 302 and the second rotating shaft 303. The fixed seats 306 are located at the midpoint between the T-shaped right angle box 301 and the limit box 305. The first rotating shaft 302 and the second rotating shaft 303 pass through the bearing 307 and are interference-fitted with the bearing 307. The functions are: the fixed seats 306 provide fixed support for the bearing 307, and the bearing 307 provides rotational support and positioning for the first rotating shaft 302 and the second rotating shaft 303, reducing the friction when the shaft rotates and preventing the shaft from deviating. At the same time, the midpoint position makes the shaft bear force evenly, further improving the operational stability and service life of the automatic unloading device 3.

[0030] The guiding and positioning device 2 includes a push plate 200, a positioning baffle 201, a second electric cylinder push rod 202, a second bushing 203, and a second sliding shaft 204. The second electric cylinder push rod 202 and the second bushing 203 are fixedly installed at the four corners of the bottom surface of the base plate 110. The second sliding shaft 204 is fixedly installed at the four corners of the bottom surface of the push plate 200, and one end of the second sliding shaft 204 is slidably installed inside the second bushing 203. The positioning baffle 201 is fixedly installed on the upper surface of the push plate 200. The platform 109 has a through-hole. The plate has a groove that matches the positioning baffle 201. The positioning baffle 201 slides in the groove on the plate 109. Its function is: the second electric cylinder push rod 202 provides power to drive the push plate 200 to move smoothly along the second bushing 203 and the second sliding shaft 204. The positioning baffle 201 moves with the push plate 200 and passes through the groove on the plate 109 to limit and position the sponge to be compressed on the plate 109, prevent the sponge from shifting during the compression process, and ensure compression accuracy and packaging quality.

[0031] The stacked compression packaging device 4 includes a stacking base plate 400 and a stacking plate 405. A stacking side plate 402 is fixedly installed on the stacking base plate 400. A bracket 408 is fixedly installed on the side of the stacking side plate 402 away from the conveyor belt 5. A second hydraulic cylinder 409 is fixedly installed on the bracket 408. The piston rod of the second hydraulic cylinder 409 passes through the bracket 408 and is fixedly connected to the upper surface of the stacking plate 405. Its function is: the stacking base plate 400 and the stacking side plate 402 form a stacked compression chamber. The conveyor belt 5 transports the sponge after primary compression to the stacking base plate 400. The extension and retraction of the second hydraulic cylinder 409 drives the stacking plate 405 to move up and down, performing secondary stacked compression on the sponge, further reducing the volume of the sponge, facilitating subsequent bundling and packaging, and improving packaging efficiency and space utilization.

[0032] The base plate 400 has a bottom threading groove 401, the inner wall of one side of the side plate 402 has a first side threading groove 403, and the side of the side plate 402 opposite to the first side threading groove 403 has a second side threading groove 404. A protrusion 406 is fixedly installed on the stacking plate 405, and the protrusion 406 is slidably installed in the first side threading groove 403. The bottom surface of the stacking plate 405 and the protrusion 406 has a plate threading groove 407. The function of the bottom threading groove 401, the first side threading groove 403, the second side threading groove 404 and the plate threading groove 407 is to cooperate with each other to facilitate the packing strap to pass through the stacked and compressed sponge, so as to realize the all-round binding of the sponge. The sliding cooperation between the protrusion 406 and the first side threading groove 403 can guide and limit the movement of the stacking plate 405, ensure the smooth stacking and compression, and prevent the stacking plate 405 from deviating.

[0033] Working principle: After the device is started, the sponge to be processed is first placed on the platform 109 of the compressor 1. At this time, the guide positioning device 2 starts to work. The second electric cylinder push rod 202 provides power to push the push plate 200 to move smoothly along the second bushing 203 and the second sliding shaft 204. The positioning baffle 201 fixed on the upper surface of the push plate 200 moves synchronously with the push plate 200, passes through the preset adapter groove on the platform 109, and accurately limits and positions the sponge on the platform 109 to prevent the sponge from shifting during the subsequent compression process and ensure compression accuracy.

[0034] After positioning, compressor 1 begins to execute the first-stage compression action. Frame 100 serves as the overall support carrier for compressor 1. The four first hydraulic cylinders 102 at the four corners of its top surface are connected to the hydraulic system via hydraulic synchronous motors. Under the control of the hydraulic system, the four first hydraulic cylinders 102 achieve synchronous extension and retraction. Their piston rods penetrate frame 100 and drive pressure plate 101 to move smoothly downwards, compressing the positioned sponge on platform 109. The metal pad 108 fixed on platform 109 provides stable support for sponge compression, preventing uneven force during compression and deformation, until the sponge is fully compressed. Once the thickness is reduced to the preset level, the first stage of compression is complete. After the first stage of compression, the ironing sealer 104 begins preparation. The first mounting plate 103 provides mounting support for the ironing seal-related components. The first electric cylinder push rod 105 fixed on its surface is activated, driving the ironing sealer 104 to slide smoothly along the first bushings 106 on both sides and the first sliding shaft 107 on the ironing sealer 104. The ironing sealer 104 is adjusted to the sealing position required for the sponge packaging. Then, the packing tape wrapped around the surface of the compressed sponge is ironed and sealed to ensure that the packing tape is firmly attached to the sponge, completing the initial packaging after the first stage of compression.

[0035] After initial packaging, the automatic unloading device 3 is activated to automatically unload and convey the compressed sponge. The first motor 300 is fixed to the bottom of the base plate 110, and its output shaft is fixedly connected to the input end of the T-shaped right-angle box 301. After the first motor 300 starts, it outputs power, which, after being diverted by the T-shaped right-angle box 301, drives the first rotating shaft 302 and the second rotating shaft 303 connected to its two output ends to rotate synchronously. A pair of fixed seats 306 fixed to the bottom of the base plate 110 are equipped with bearings 307, and the fixed seats... 306 is located at the midpoint between the T-shaped right-angle box 301 and the limiting box 305. The central axis of the bearing 307 is aligned with the axes of the first rotating shaft 302 and the second rotating shaft 303. The first rotating shaft 302 and the second rotating shaft 303 pass through the bearing 307 and are interference-fitted with it. The bearing 307 provides rotational support and positioning for the rotating shaft, reduces friction during rotation, and prevents shaft misalignment. Simultaneously, the fixed seat 306 at the midpoint ensures even force distribution on the rotating shaft, improving operational stability. The first rotating shaft 307... 02 and the second rotating shaft 303 have reverse threads at one end inside the mounting box 308, with the same pitch and thread angle. The mounting boxes 308 on both sides are threadedly connected to the first rotating shaft 302 and the second rotating shaft 303, respectively. When the shafts rotate, the mounting boxes 308 on both sides slide synchronously towards each other under the action of the reverse threads. At the same time, the first limiting rod 304 is rotatably installed inside the limiting box 305, providing guidance and limiting for the sliding of the mounting box 308, ensuring that the mounting box 308 slides smoothly. The mounting box 308 slides to the preset position. Then, the second motor 309 fixed on one side starts, driving the first lead screw 310 in the mounting box 308 to rotate. The lever 312 is threadedly connected to the first lead screw 310 and slidably mounted on the second limit rod 311. Under the threaded transmission of the first lead screw 310, the lever 312 slides up and down along the first lead screw 310 and the second limit rod 311 to adjust to a height that matches the thickness of the sponge. Then, the lever 312 pushes the first-stage compressed and packaged sponge, pushing it from the platform 109 onto the conveyor belt 5.

[0036] Conveyor belt 5 starts, smoothly conveying the primary compressed and packaged sponge to the stacking base plate 400 of the stacking compression and packaging device 4. The stacking side plate 402 fixed on the stacking base plate 400 forms a stacking compression chamber, limiting the conveyed sponge and preventing it from shifting during the secondary compression process. The stacking compression and packaging device 4 begins to perform the secondary compression action. A second hydraulic cylinder 409 is installed on the bracket 408 fixed on the side of the stacking side plate 402 away from the conveyor belt 5. After the second hydraulic cylinder 409 starts, its piston rod passes through the bracket 408 and drives the stacking plate 405 to move downward. The protrusion 406 fixed on the stacking plate 405 is slidably installed in the first side wire groove 403 on the inner wall of the stacking side plate 402, which guides and limits the movement of the stacking plate 405, ensuring that the stacking plate 405 is flat. The device moves downwards steadily, performing secondary layering and compression on the sponge on the stacking base plate 400 to further reduce the sponge volume and improve packaging density and space utilization. After secondary compression, final bundling is performed. The bottom threading groove 401 on the stacking base plate 400, the first side threading groove 403 and the second side threading groove 404 on both sides of the stacking side plate 402, and the plate threading groove 407 on the bottom surface of the stacking plate 405 and the protrusion 406 cooperate with each other to facilitate the packing straps to pass through the stacked and compressed sponge, achieving all-round bundling of the sponge. After bundling, the device is reset and awaits the processing of the next batch of sponges. The entire process is fully automated, with all components working together to ensure the stability and accuracy of sponge compression and improve packaging efficiency, realizing the integrated operation of multi-stage compression and automatic bundling of sponges.
