Description

Technical Field

[0001] The invention relates to a tool kit packaging machine and a working method thereof, belonging to the technical field of tool kit packaging machines. Background Art

[0002] The existing tool kit packaging is simply to put a sealed bag on it and then directly put it into a carton for packaging. The tool kit packaged in this way is large in size, and a carton can only hold a small number of tool kits. It takes up more space during transportation and will greatly increase transportation costs. In addition, it is simply to put a sealed bag on it, but the bag opening of the sealed bag is generally not sealed, which can easily cause the tool kit to get damp and affect the quality of the tool kit. If the bag opening of the sealed bag is directly sealed, there will be air in the sealed bag, which will make the sealed bag larger in size, so that the number of tool kits that can be loaded into the carton is even smaller. In response to the above shortcomings, the present invention proposes a tool kit packaging machine and a working method thereof. Summary of the Invention

[0014] A further improvement is that the hot-press sealing assembly includes a second fixed seat, and a third retractor is vertically provided on the top surface of the second fixed seat, and a sealer is horizontally provided at the lower end of the third retractor, and a plurality of second supporting slide bars penetrating the second fixed seat are vertically provided on the top surface of the sealer;

[0015] The sealer includes a distance adjusting seat, and a distance adjusting slot is provided on the front side of the distance adjusting seat, and a screw adjustment member and a drag plate are longitudinally sleeved in the middle of the distance adjusting slot.

A heating plate is provided on the left side of the sealing hot pressing head, and the sealing hot pressing head is made of copper.

[0016] In addition, the present invention also provides a working method of the tool kit packaging machine, which is as follows:

[0017] First, place the tool kit in the sealing bag flat on the middle of the inner side of the top surface of the packaging platform, with the bag opening extending outward through the space between the high-temperature resistant base pad and the hot-press sealing assembly;

[0018] Then the first and second edge-smoothing assemblies are synchronously extended toward the tool bag, so that the two edge-smoothing buffer plates simultaneously squeeze and flatten the left and right sides of the tool bag, and the rear side of the tool bag is flattened against the rear side of the L-shaped packaging table;

The sealing hot pressure head heated by the heating plate cooperates with the high-temperature resistant base pad to heat-press and fit the bag opening to seal the bag, completing the compression packaging of the entire edge of the tool kit.

[0021] The beneficial effects of the present invention are:

[0022] The present invention provides a tool kit packaging machine and a working method thereof. A tool kit packaging machine is formed by a structural combination design of an edge-straightening packaging table group consisting of an L-shaped packaging table, a first edge-straightening component, a second edge-straightening component, a first buffer sealing table component, and a high-temperature resistant bottom pad, and a frame, a first telescoping device, a pressure plate, a soft pressure pad, a hot pressing sealing component, and an operating table. The cooperation of the L-shaped packaging table, the first edge-straightening component, and the second edge-straightening component of the equipment can first squeeze and shrink the convex parts of the left, right, and rear sides of the tool kit to make them flush, so that the soft pressure pad can offset the deformation and compact the sides of the tool kit when it descends vertically. The volume of the tool kit after being compressed by the soft pressure pad is significantly reduced, and the structure is square, which is convenient for subsequent flush placement and packing, so that the number of packings is significantly increased, and the transportation cost is reduced.

[0023] In addition, the combination of the high-temperature resistant base pad and the hot-pressing sealing component can use hot-pressing to seal the sealing bag on the surface of the tool kit, so that the tool kit can maintain its shape after being compressed on the entire side and will not rebound and increase its volume again.

[0024] In addition, the corresponding buffering descending function design of the first edge-straightening component, the second edge-straightening component and the first buffer sealing component and the second buffer sealing component can keep the first edge-straightening component and the second edge-straightening component in a squeezed and pushed state after the edge is straightened, helping to keep the side of the tool bag flat after the soft pressure pad is pressed down, and there will be no jamming problem.

The sealer 63 includes a distance adjusting seat 631, and a distance adjusting slot 632 is opened through the front side surface of the distance adjusting seat 631, and a screw adjustment member 633 and a drag plate 634 are longitudinally sleeved in the middle part of the distance adjusting slot 632. The lower end of the drag plate 634 extends to the outside of the bottom surface of the distance adjusting seat 631. A sealing hot pressing head 635 is horizontally arranged on the bottom surface of the drag plate 634. A heating plate 636 is arranged on the left side of the sealing hot pressing head 635. The sealing hot pressing head 635 is made of copper.

[0043] Working principle:

[0044] Before the tool kit is packaged, it is necessary to replace the soft pressure pad 5 of the corresponding area according to the area of the top surface of the tool kit. It is also necessary to adjust the extension stroke of the second telescoping device 222 on the first edge-straightening component 22 and the second edge-straightening component 23. In addition, it is also necessary to adjust the longitudinal position of the sealing hot pressure head 635 on the hot pressing sealing component 6. The above adjustments can make the packaging machine adapt to the compression and edge-straightening packaging of tool kits of various specifications.

[0045] When packaging the equipment, the tool kit in the sealing bag is first placed flat on the inner middle of the top surface of the packaging table body 211, and the bag opening of the sealing bag extends outward through the space between the high-temperature resistant base pad 26 and the hot-press sealing assembly 6. This step can be performed manually, or a horizontal conveyor line can be installed at the front end of the equipment to use an auxiliary robot to push in and out.

[0046] Then, the first edge-smoothing assembly 22 and the second edge-smoothing assembly 23 are simultaneously extended toward the tool bag, so that the two edge-smoothing buffer plates 225 simultaneously squeeze and flatten the left and right sides of the tool bag, and the rear side of the tool bag is flattened against the rear side of the L-shaped packaging platform 21.

[0047] It should be noted that when the first edge straightening assembly 22 is used for edge straightening, the second telescopic device 222 is extended, and the edge straightening seat group 223 and the edge straightening buffer plate group 225 are pushed to the right horizontally, so that the right side of the L-shaped edge straightening plate 2251 squeezes the protruding part of the left side of the tool kit, so that the protruding part of the left side of the tool kit is squeezed inward and flattened. This is because the extension stroke of the second telescopic device 222 has been adjusted in advance. In addition, the protruding part of the rear side of the tool kit will be pushed backward and squeezed flat when the material is discharged.

[0048] Then the first retractor 3 descends, passes through the pressure plate 4, and causes the soft pressure pad 5 to descend vertically and deform and squeeze the top surface of the tool bag. During this process, the tool bag will be softly compressed and the air will be expelled, and the tool bag will be thinner. At the same time, the left and right sides of the soft pressure pad 5 will also be deformed and squeezed into the inside of the whole-edge buffer plate group 225 for buffering descent. When the whole-edge buffer plate group 225 is pressed and buffered, it will correspondingly press one of the buffer sealing members to buffer and descend to prevent it from getting stuck, so that the tool bag with multiple sides flush and compressed in the sealed bag is obtained;

[0049] It should be noted that when the soft pressure pad 5 descends vertically and softly presses against each other, because the pressure pad body 52 is made of silicone material and is combined with the design of the deformation retraction cavity 53, the deformation performance of the pressure pad body 52 is stronger, and the metal parts on the tool bag will not be damaged by hard extrusion. When the edge buffer plate group 225 is pressed and buffered, the first spring 2253 is compressed, and the second slide bar 242 slides down into the lower end of the first slide bar through-hole 2121, allowing the lower end of the L-shaped edge plate 2251 to descend below the top surface of the packaging platform body 211. At this time, the buffering descending function design of the buffer sealing member with the top surface of the packaging platform body 211 horizontally aligned can play an anti-stuck role, so that the left and right sides of the pressure pad body 52 can compact the left and right sides of the tool bag after leveling, and there will be no problem of the left and right sides of the tool bag being stuck and not compressed in place by the L-shaped edge plate 2251 after leveling.

[0050] In addition, there is a 1-2 cm gap between the rear side of the pressure pad body 52 and the rear end of the packaging table body 211. Therefore, when the pressure pad body 52 descends, it will not be stuck by the rear end of the L-shaped edge plate 2251. However, after the pressure pad body 52 is deformed, the 1-2 cm gap between the rear side of the pressure pad body 52 and the rear end of the packaging table body 211 will be filled, so that the rear end of the pressure pad body 52 can softly press against the rear side of the tool bag.

[0051] Finally, the third telescopic device 62 descends, driving the sealer 63 to descend vertically. The sealing hot pressure head 635 heated by the heating plate 636 cooperates with the high temperature resistant base pad 26 to heat and press the bag opening to seal the bag, completing the compression packaging of the entire edge of the tool kit.

[0052] It should be noted that, since the tool kit has been compressed, the sealing bag will now be tightly attached to the surface of the tool kit, and all the air has been expelled. After the sealing bag is sealed by the cooperation of the sealing hot pressure head 635 and the high temperature resistant base pad 26, the tool kit will remain in a compressed state inside the sealing bag. At this time, the tool kit has a flat square structure and its volume is significantly reduced. There will be no uneven bulges on the sides of the tool kit, which is convenient for subsequent stacking and packing.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

The sealing hot pressure head heated by the heating plate cooperates with the high-temperature resistant base pad to heat-press and fit the bag opening to seal the bag, completing the compression packaging of the entire edge of the tool kit.
