Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular discloses a compression packaging machine used for packaging round sponge blocks. Background Art

[0002] In the sponge production process, it is often necessary to cut the sponge blocks into cylindrical shapes according to customer needs, and then compress and pack the cut sponge blocks to reduce the space occupied by the sponge blocks during transportation and reduce transportation costs.

[0003] The existing compression and packaging machine for sponges is mainly composed of a compression table, a stand, a pressing plate, a hydraulic cylinder and a sealing device. During the compression and packaging process of the sponge block, the sponge block is first put into a plastic bag, and then placed on the surface of the compression table. The hydraulic cylinder then drives the pressing plate to move downward, thereby compressing the sponge block into a thin plate shape. Finally, the sealing device is used to seal the open end of the packaging bag to complete the packaging.

[0004] For example, the utility model patent with application number 202323139956.3 discloses a sponge packing device, including a processing table and an extrusion device installed on the surface of the processing table. The surface of the processing table is provided with a lower clamping member. The outer side of the processing table is provided with guide rails at both ends of the lower clamping member. An upper clamping member that slides in a vertical direction is installed in the guide rail. A reset spring is installed between the upper clamping member and the guide rail. The upper clamping member is clamped with the lower clamping member by the tension of the reset spring. The sponge packing device disclosed in the patent usually adopts the above steps when compressing and packing the sponge. Although the compression and packing process of the sponge block is realized, there are still some shortcomings when it is used for packing and compressing cylindrical sponge blocks. First, plastic packaging bags are usually rectangular, which makes it difficult to bag cylindrical sponge blocks; second, after the cylindrical sponge block is compressed, the four corners of the plastic packaging bag are not filled with sponge, which not only leads to low space utilization of the plastic bag, but also the plastic bag at the corners is prone to damage. After damage, external gas fills into the bag, causing the sponge block to expand easily, increasing the volume of the sponge block during transportation; third, the compressed sponge block expands and returns to its original cylindrical shape. Therefore, in view of the technical problems existing in the existing sponge packaging device in the process of compressing and packaging circular sponge blocks, this application proposes a newly designed circular sponge block compression and packaging machine to solve the above technical problems. Summary of the invention

[0005] The present invention aims to provide a compression packaging machine for packaging circular sponge blocks, so as to solve the technical problems existing in the existing sponge packaging device during the compression packaging process of circular sponge blocks.

[0006] The present invention is achieved through the following technical solutions: A circular sponge block compression and packaging machine comprises a base and a feeding mechanism, wherein the feeding mechanism is connected to one end of the upper surface of the base, a circular opening is provided at the center of the upper surface of the base, an extrusion bagging cylinder is provided at the lower end of the circular opening, and a compression mechanism is provided just above the circular opening; The compression mechanism includes a second cylinder fixedly arranged above the pedestal, the lower end of the second cylinder is connected to a cross frame, the lower end of the cross frame is fixedly connected to the first ring plate, the upper surface of the first ring plate is concentrically rotatably provided with a second ring plate, and a driving component for driving the second ring plate to rotate is arranged on the cross frame, the second ring plate is provided with a plurality of arc guide strip openings in an annular array, the first ring plate is provided with a radial strip opening corresponding to each arc guide strip opening, the first ring plate located below the radial strip opening is fixed with a slide rail bar arranged radially, the slide rail bar is provided with a moving strip for upper limit sliding, the radial outer end of the moving strip is connected with a guide column that simultaneously acts on the radial strip opening and the arc guide strip opening, the radial inner end of the moving strip is connected with an arc clamping plate, and the outer sides of the plurality of arc clamping plates are commonly penetrated by an elastic steel sheet in the shape of an annular ring and a non-closed loop, a hydraulic cylinder is arranged on the cross frame, and the lower end of the hydraulic cylinder is connected with a pressing plate assembly that passes through the center of the first ring plate and the second ring plate and extends into the extrusion bagging cylinder.

[0007] During the compression and packaging process of the circular sponge block, the compression and packaging machine disclosed in the present invention first places the circular sponge block above the circular opening, then starts the second cylinder to push the entire compression mechanism downward and press it onto the circular sponge block, and then rotates the second ring plate through the driving assembly. During the rotation of the second ring plate, the multiple moving strips are synchronously contracted toward the center of the circle along the slide rails through the squeezing action of the arc-shaped guide strip opening and the guide column, combined with the guiding action of the radial strip opening on the guide column.

[0008] During the process of the moving bar shrinking toward the center of the circle, the elastic steel sheet arranged on the periphery of the arc-shaped clamp plate will shrink and deform under the action of its own elastic force, so that the elastic steel sheet and the arc-shaped clamp plate will compress the circular sponge block radially inward into a cylindrical shape with a smaller diameter until it is reduced to a size equivalent to the size of the circular mouth. Then the hydraulic cylinder is started to push the pressing plate assembly downward, and the pressing plate assembly will push the reduced circular sponge block through the circular mouth into the extrusion bagging cylinder, which will further shrink it and enter the packaging bag below until it completely falls out of the extrusion bagging cylinder, and then the operator can seal the packaging bag. During the compression and packaging process of the entire circular sponge block, the sponge block is first radially retracted, and then axially compressed during the process of pushing the extrusion bagging cylinder downward. Finally, the compressed sponge block can be placed in the packaging bag in a cylindrical state, so that the packaging bag can be fully filled, and the entire sponge block is evenly squeezed, which will not affect its initial state after subsequent expansion.

[0009] As a further configuration of the above scheme, the extrusion bagging cylinder includes a truncated cone section compression cylinder connected to the lower end of the circular mouth, and the lower end of the truncated cone section compression cylinder is connected to a cylindrical section compression cylinder.

[0010] As a further configuration of the above scheme, the pressure plate assembly includes a large circular pressure plate, a circular storage groove is provided on the lower surface of the large circular pressure plate, a small circular pressure plate is arranged in the circular storage groove, an electromagnet is fixed on the large circular pressure plate for adsorbing the small circular pressure plate, and the lower end of the hydraulic cylinder extends into the circular storage groove and is connected to the small circular pressure plate.

[0011] In the present invention, through the special design of the extrusion bagging cylinder and the pressing plate assembly, after the sponge block compressed by the compression mechanism enters the truncated cone section compression cylinder, it will further radially shrink and become smaller under the extrusion of the large circular pressing plate, and then after the small circular pressing plate is separated from the large circular pressing plate, the small circular pressing plate will completely squeeze the sponge block into the cylindrical section compression cylinder, and finally be discharged from the cylindrical section compression cylinder in a state of progress, so that the sponge block can be further compressed in volume, thereby reducing the space after compression and packaging.

[0012] As a further configuration of the above scheme, rotating rods are connected to both sides of the outer circumferential surface of the truncated cone compression cylinder, bag mouth clamps are provided at the ends of the rotating rods, and a hydraulic telescopic rod for driving the rotating rod is connected to the truncated cone compression cylinder.

[0013] Through the above-mentioned improved design, after the packaging bag is put on the outer surface of the cylindrical compression cylinder, the hydraulic telescopic rod can be used to drive the two bag opening clamps to clamp and fix the packaging bag on its surface, thereby preventing the packaging bag from being blown down due to the action of internal gas during the squeezing of the sponge block, so that the sponge block that has been squeezed and pushed down can smoothly enter the interior of the packaging bag.

[0014] As a further configuration of the above scheme, a carrier plate is fixed in the pedestal below the extrusion bagging cylinder, movable seats that move toward or away from each other are arranged on both sides of the carrier plate, and a heat sealing device is arranged at one end where the two movable seats are close to each other.

[0015] As a further configuration of the above scheme, slide rails are provided on the upper surfaces of both sides of the carrier plate, the movable seats are slidably arranged on the corresponding slide rails, and a transmission mechanism for driving the two movable seats to move closer to or away from each other is provided on the carrier plate.

[0016] As a further configuration of the above scheme, a convex ring is extended upward from the inner ring of the first ring plate, and a gear ring is extended upward from the inner ring of the second ring plate and is rotatably connected to the convex ring. The drive assembly includes a drive motor arranged on a cross frame, and a gear meshing with the gear ring is arranged on the motor shaft of the drive motor.

[0017] The present invention further adopts the above-mentioned improved design. After the sponge block is squeezed into the packaging bag, in the process of pushing the packaging bag downward, when the bag mouth of the packaging bag is removed from the cylindrical compression cylinder, the two movable seats can be brought close to each other in the first time, and the sealing of the packaging bag can be sealed by the heat sealing device on the two movable seats, so that the compression, packaging and sealing operations of the entire sponge block can be completed at one time.

[0018] As a further configuration of the above solution, a first cylinder is provided at the end of the pedestal away from the feeding mechanism, and a positioning push plate is connected to the end of the first cylinder.

[0019] As a further configuration of the above solution, the front side of the pedestal is opened, and a control box is arranged on the side wall of the pedestal.

[0020] As a further configuration of the above solution, a plurality of columns are evenly arranged on the upper surface of the pedestal, the upper ends of the plurality of columns are commonly connected to a top plate, and the second cylinder is fixedly arranged on the top plate.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The compression packaging machine disclosed in the present invention is used for packaging circular sponge blocks. The circular sponge blocks are firstly radially compressed and then axially extruded so that they are finally discharged from the lower end opening of the extrusion bagging cylinder and loaded into the packaging bag. During the whole process, there is no need for operators to first bag the sponge blocks and then compress and package them. Not only does it avoid the problem of difficulty in bagging circular sponge blocks, but the compressed sponge blocks can fully fill all corners of the packaging bag, and there is no problem of easy damage to the corners of the packaging bag. In addition, during the whole compression process, it can ensure that the circular sponge blocks are compressed evenly to the greatest extent, and their initial shape after expansion will not be affected.

[0022] The compression packaging machine in the present invention utilizes a specially designed compression mechanism to achieve radial contraction of the circular sponge block, and through the special design of the extrusion bagging cylinder and the pressure plate assembly, the sponge block can be further radially contracted and axially compressed during the process of moving down along the extrusion bagging cylinder, so that the entire sponge block is compressed to a smaller size, reducing the space after compression packaging and ensuring the quality of the sponge block during the compression packaging process.

[0023] The present invention further provides a bag opening heat sealing mechanism below the extrusion bagging cylinder. After the sponge block is discharged from the extrusion bagging cylinder, the bag opening of the packaging bag can be sealed by the hot air device in the first place to ensure the sealing effect after packaging, making the compression and packaging process of the sponge block faster and more convenient.

Then, a through hole for passing the elastic steel sheet 309 is opened on the outer surface of the arc-shaped clamping plates 308. When multiple arc-shaped clamping plates 308 are synchronously radially inwardly moved together, the elastic steel sheet 309 is reduced in diameter under the action of the elastic steel sheet 309, and when multiple arc-shaped clamping plates 308 are synchronously radially expanded outwardly, the elastic steel sheet 309 is expanded in diameter under the action of the elastic steel sheet 309.

[0030] A second ring plate 310 is arranged on the upper surface of the first ring plate 303, and a gear ring 311 is extended upward from the inner ring of the second ring plate 310 and is rotatably connected to the convex ring 304. Then a driving motor 312 is fixedly installed on the cross frame 302, and a gear 313 meshing with the gear ring 311 is arranged at the lower end of the motor shaft of the driving motor 312, so that the second ring plate 310 can rotate on the upper surface of the first ring plate 303 under the power input of the driving motor 312. At the same time, arc-shaped guide strip openings 3101 corresponding to each radial strip opening 3031 are opened in an annular array on the second ring plate 310, and the two ends of the arc-shaped guide strip openings 3101 are respectively arranged near the outer edge and one end of the center of the second ring plate 310, and then the guide column 307 extending out of the radial strip openings 3031 is extended to the corresponding arc-shaped guide strip openings 3101.

[0031] A hydraulic cylinder 314 is fixedly mounted on the horizontal frame 302 just above the center of the first ring plate 303 and the second ring plate 310, and a large circular pressing plate 315 capable of passing through the convex ring 304 is connected to the lower end of the hydraulic cylinder 314, a circular receiving groove 3151 is provided at the center of the lower surface of the large circular pressing plate, and a small circular pressing plate 316 is arranged in the circular receiving groove 3151, and the lower end of the hydraulic cylinder 314 extends into the circular receiving groove 3151 and is fixedly connected to the small circular pressing plate 316. In addition, an electromagnet 317 extending into the circular receiving groove 3151 is arranged on the upper surface of the large circular pressing plate 315, and the small circular pressing plate 316 can be adsorbed and fixed by the magnetic attraction of the electromagnet 317, so that the large circular pressing plate 315 and the small circular pressing plate 316 are fixed as one.

[0032] Reference Figure 1 , Attachment Figure 2 and attached Figure 7 A circular opening 101 with a diameter slightly larger than that of the large circular pressure plate 315 is provided on the upper surface of the pedestal 1 just below the center of the compression mechanism 3. The extrusion bagging cylinder 4 includes a conical section compression cylinder 401 connected to the lower end of the circular opening 101. A cylindrical section compression cylinder 402 is connected to the lower end of the conical section compression cylinder 401. The inner diameter of the cylindrical section compression cylinder 402 is slightly larger than the diameter of the small circular pressure plate 316.

[0033] During use of the circular sponge block compression packaging machine disclosed in this embodiment 1, the operator first puts the packaging bag on the outside of the cylindrical compression cylinder 402, and then uses the feeding mechanism 2 to transport the circular sponge block to the upper surface of the base 1, and then starts the first cylinder 6 and pushes the circular sponge block to be positioned directly above the circular opening 101 through the positioning push plate 7.

[0034] Next, the second cylinder 301 is started to push the entire compression mechanism 3 downward until the lower ends of the arc-shaped clamping plate 308 and the elastic steel sheet 309 almost touch the upper surface of the pedestal 1. Then the driving motor 312 is started to rotate the second ring plate 310 under the action of the ring gear 311 and the gear 313. During the rotation of the second ring plate 310, the guide column 307 is simultaneously acted upon by the arc-shaped guide strip opening 3101 and the radial strip opening 3031, so that all the moving strips 306 move radially inward along the slide rail 305, so that the multiple arc-shaped clamping plates 308 are synchronously radially inwardly moved, and the elastic steel sheets 309 interspersed in all the arc-shaped clamping plates are reduced in diameter under the action of the elastic steel sheets 309, and the circular sponge block on the upper surface of the pedestal 1 begins to be radially compressed and reduced until the diameter of the circular sponge block is compressed to a diameter slightly smaller than the diameter of the circular opening 101.

[0035] After the compression stage is over, the hydraulic cylinder 314 is started to push the large circular pressure plate 315 and the small circular pressure plate 316 downward, and the shrunken circular sponge block is pressed into the truncated cone section compression cylinder 401 under the action of the large circular pressure plate 315. Then, in the process of continuing to extend the hydraulic cylinder 314, the magnetic attraction force of the electromagnet 317 is not enough to offset the downward pressure of the hydraulic cylinder 314, so that the small circular pressure plate 316 continues to move downward in the circular receiving groove 3151. Then, under the action of the small circular pressure plate 316, the compressed sponge block is squeezed and pushed into the cylindrical section compression cylinder 402, and finally pushed from the cylindrical section compression cylinder 402 and into the packaging bag. Example 2

[0036] Example 2 discloses a circular sponge block compression packaging machine that is further optimized and improved based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0037] Reference Figure 2 and attached Figure 7 In this embodiment 2, a bag opening clamping assembly is provided on the extrusion bagging cylinder 4. Specifically, the bag opening clamping assembly includes a rotating rod 10 rotatably connected to both sides of the outer circumference of the truncated cone compression cylinder 401. The lower ends of the two rotating rods 10 are connected to bag opening clamping plates 11. In addition, two hydraulic telescopic rods 12 are rotatably connected to the truncated cone compression cylinder 401, and the movable ends of the two hydraulic telescopic rods 12 are respectively connected to the corresponding rotating rods 10. After the packaging bag is inserted into the cylindrical compression cylinder 402, the hydraulic telescopic rod 12 is started so that the two bag opening clamping plates 11 clamp the packaging bag to the outer surface of the cylindrical compression cylinder 402, so as to prevent the packaging bag from being blown from the cylindrical compression cylinder 402 to the outer surface of the cylindrical compression cylinder 402 due to the action of gas during the downward extrusion of the compressed sponge.

[0038] In addition, a carrier plate 13 is fixedly arranged in the pedestal 1 below the extrusion bagging cylinder 4, and slide rails 14 are arranged at both the left and right ends of the carrier plate 13, and then a moving seat 15 is arranged on the slide rails 14, and a heat sealing device is arranged at one end where the two moving seats 15 are close to each other, and a transmission mechanism for realizing the two moving seats 15 to move closer to or farther from each other is also arranged on the carrier plate 13. The specific transmission mechanism includes a transmission motor 16, and a transmission gear 17 is arranged on the motor shaft of the transmission motor 16, and then racks 18 are connected to the two moving seats 15, and the two racks 18 are parallel and meshed with the transmission gear 17. When the compressed sponge is squeezed into the packaging bag, the clamping effect of the bag mouth clamping assembly on the packaging bag is first released, and then the packaging bag is pulled downward from the cylindrical compression cylinder 402, and after being pulled out, the transmission mechanism makes the two moving seats 15 move closer to each other, and finally the bag mouth of the packaging bag is heat-sealed by the heat sealing device.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
