Description

Technical Field

[0001] The invention relates to a packaging machine, in particular to a semi-automatic compression sealing packaging machine, which is mainly suitable for packaging products made of soft materials with much internal air. Background Art

[0002] After each piece of soft material products (such as gloves, towels, quilt covers, pillow cases, etc.) is individually packaged, it is usually necessary to put multiple individual packages into a large packaging bag for combined packaging. Since the products are made of soft materials and have not been vacuumed during individual packaging, when combining them, if multiple individual packaging bags are directly stacked together and put into a large packaging bag, there will be a lot of air between the individual packaging bags, causing the individual packaging bags to bulge against each other and making it difficult to put them into the large packaging bag. They need to be put into the large packaging bag one by one manually, which has low packaging efficiency and high labor intensity for workers. In addition, a large amount of air remains in the combined packaging bag. After sealing, the combined packaging bag is large in size and occupies a large space, increasing storage and transportation costs. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a semi-automatic compression sealing packaging machine which can reduce the labor intensity of workers, improve packaging efficiency, reduce the volume of combined packaging bags, and reduce storage and transportation costs.

[0004] The technical scheme of the semi-automatic compression sealing packaging machine of the present invention is as follows: it comprises a frame, a compression exhaust mechanism and an exhaust sealing mechanism are arranged on the frame, the compression exhaust mechanism comprises an upper die and a lower die, the lower die is fixed to the frame, rotating shafts are formed on both sides of the upper die, an air motor and a bearing seat are arranged on the frame, the output shaft of the air motor is connected to one end of the rotating shaft, the other end of the rotating shaft is rotatably matched with the bearing seat, a push cylinder is arranged under the frame, the piston rod of the push cylinder is connected to the mounting plate, a push rod is arranged on the mounting plate, the other end of the push rod is connected to the push plate, the push plate is arranged between the upper and lower dies, the The exhaust and sealing mechanism includes a compression exhaust device, a lifting hot pressing and sealing device and a rotary feeding device. The compression exhaust device includes a guide rod, the upper end of the guide rod is connected to the exhaust pressure plate, the lower end of the guide rod passes through the frame and is connected to the mounting plate, an exhaust cylinder is arranged on the mounting plate, and the piston rod of the exhaust cylinder is connected to the lower end of the frame. The lifting hot pressing and sealing device includes a hot pressing cylinder, and the piston rod of the hot pressing cylinder is connected to the hot pressing mold. The rotary feeding device includes a rotary cylinder, which is fixed to the frame, and a rotary base is arranged on the frame, and the output shaft of the rotary cylinder is connected to the rotary base.

[0005] The present invention discloses a semi-automatic compression sealing packaging machine. When a plurality of independent packaging bags are combined and packaged, an upper die is in an upwardly opened state, and a worker stacks the plurality of independent packaging bags and places them on a lower die. After the bags are neatly stacked, a control mechanism (the specific structure of the control mechanism is an existing technology) is used to control the machine to start working, and an output shaft of an air motor drives a rotating shaft to rotate, and the rotating shaft drives the upper die to rotate downward, and the rotating shaft on the other side of the upper die cooperates with a bearing seat, and the upper die rotates downward and cooperates with the lower die to squeeze the stacked independent packaging bags, so that the air between the independent packaging bags is discharged and the volume is reduced. At this time, a worker puts the combined packaging bag on the outer walls of the upper and lower dies, and then the control mechanism controls the push cylinder to work, and the piston rod of the push cylinder drives the mounting plate to move, and the mounting plate drives the push rod, and the push rod drives the push plate to move along the upper and lower dies, and the push plate pushes the compressed plurality of stacked independent packaging bags into the combined bag. The exhaust cylinder is controlled by the control mechanism at this time, and the piston rod of the exhaust cylinder is against the lower end of the frame, and the exhaust cylinder is pushed downward in the opposite direction, and the exhaust cylinder drives the mounting plate to move downward, and the mounting plate drives the exhaust pressure plate to move downward through the guide rod, and the exhaust pressure plate squeezes the combined packaging bag placed on the rotating base downward to discharge most of the air in the combined packaging bag. Then the piston rod of the hot pressing cylinder drives the hot pressing mold to move upward, and the hot pressing mold corresponds to the bag opening of the combined packaging bag. The hot pressing mold moves upward and cooperates with the lower end of the exhaust pressure plate to perform hot pressure sealing on the bag opening of the combined packaging bag. Finally, the exhaust pressure plate is reset upward, and the hot pressing mold is reset downward. The rotating base is driven by the rotating cylinder to rotate outward, and the rotating base pushes out the sealed combined packaging bag. A packaging box can be placed on one side of the machine, and the combined packaging bag automatically falls into the packaging box. The semi-automatic compression sealing packaging machine of this scheme first compresses multiple superimposed independent packaging bags through the compression exhaust mechanism to facilitate the insertion of combined packaging bags, and then squeezes out the air in the combined packaging bags through the exhaust sealing mechanism, and heat-presses and seals them, thereby improving packaging efficiency and reducing the labor intensity of workers. A large amount of air in the combined packaging bags is exhausted before heat-pressing and sealing, which can effectively reduce the volume of the combined packaging bags and is beneficial for warehousing and transportation. In addition, when the combined packaging bags are placed in the exhaust sealing mechanism for exhaust and heat-pressing, the compression exhaust mechanism can work at the same time, and the two mechanisms can work synchronously, further improving production efficiency.

[0006] The semi-automatic compression sealing packaging machine of the present invention has a limit cylinder arranged below the frame, a piston rod of the limit cylinder is connected to a lifting plate, a limit rod is arranged on the lifting plate, and the limit rod passes through the frame and corresponds to the front and rear sides of the lower die. When people stack and place multiple independent packaging bags on the lower die, the limit cylinder drives the lifting plate to move upward, and the lifting plate drives the limit rod to move upward. The limit rod is located at the front and rear sides of the lower die, and the front and rear sides of the independent packaging bag on the lower die are limited to prevent the independent packaging bag from shifting and being unable to be inserted into the combined packaging bag.

[0007] The number of the limiting rods is four or more.

[0008] The frame is provided with a guide seat, and the push rod is matched with the guide seat. The push rod passes through the guide seat, and the guide seat guides the movement of the push rod to ensure that the movement and guidance are accurate.

[0009] The frame is provided with a connecting seat, and a connecting shaft is provided between the connecting seat and the rotating base. With the connecting seat and the connecting shaft, the rotating base can move reliably when rotating.

[0010] A bag mouth tensioning device is arranged on the frame, and the bag mouth tensioning device comprises a fixing seat, which is fixed to the frame. A left tensioning cylinder and a right tensioning cylinder are arranged on the fixing seat, and the left and right tensioning cylinders are fixed to the fixing seat. The piston rod of the left tensioning cylinder is connected to the left tensioning rod, and the piston rod of the right tensioning cylinder is connected to the right tensioning rod. The heads of the left and right tensioning rods are respectively provided with elbows. The left and right tensioning rods can be made of steel wire with a certain elasticity. When the combined packaging bag is placed on the rotating base, the bag opening faces the left and right tensioning rods, and the bag opening is put on the elbows of the left and right tensioning rods. Then the left tensioning cylinder drives the left tensioning rod and the left elbow to move to the left, and the right tensioning cylinder drives the right tensioning rod and the right elbow to move to the right, so that the bag opening is stretched and tensioned, and then the exhaust pressure plate is pressed down to discharge the air of the combined packaging bag. Finally, the piston rod of the hot pressing cylinder drives the hot pressing mold to move upward, and the hot pressing mold cooperates with the exhaust pressure plate to perform hot pressing and sealing on the tensioned bag opening. Since the bag opening is stretched and tensioned, it is beneficial to hot pressing and sealing the bag opening, ensuring the sealing of the seal and avoiding the seal being not sealed due to wrinkles on the bag opening during sealing.

[0011] An air bag is arranged at the lower end of the exhaust pressure plate. Since the air bag is elastic, after the combined packaging bag is compressed by the air bag, the air bag deforms elastically along with the surface of the combined packaging bag, which is more conducive to exhausting the air in the combined packaging bag, especially the air in the corners of the combined packaging bag, so that the package volume after sealing can be further reduced.

After stacking them neatly, the control mechanism (the specific structure of the control mechanism is the existing technology) controls the machine to start working, and the output shaft of the air motor 24 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the upper die 21 to rotate downward, and the rotating shaft on the other side of the upper die cooperates with the bearing seat 25. The upper die rotates downward and cooperates with the lower die to squeeze the stacked independent packaging bags, so that the air between each independent packaging bag is discharged and the volume is reduced. At this time, the worker puts the combined packaging bag on the outer walls of the upper and lower dies 21 and 22, and then the control mechanism controls the push cylinder 26 to work, and the piston rod of the push cylinder drives the mounting plate 27 to move, and the mounting plate drives the push rod 28, and the push rod drives the push plate 29 to move along the upper and lower dies 21 and 22, and the push plate pushes the compressed multiple stacked independent packaging bags into the combined packaging bag, and then the combined packaging bag is packed.

The hot pressing mold moves upward and cooperates with the lower end of the exhaust pressure plate 42 to perform hot pressing and sealing on the bag opening of the combined packaging bag.

There are more than four limit rods 32. A guide seat 33 is set on the frame 1, and the push rod 28 cooperates with the guide seat. The push rod 28 passes through the guide seat 33, and the guide seat guides the movement of the push rod to ensure that its movement is accurate. A connecting seat 49 is set on the frame 1, and a connecting shaft 50 is set between the connecting seat and the rotating base 48.
