Description

Technical Field

[0001] The invention belongs to the technical field of sealing wet wipes packaging bags, and in particular relates to an automatic film sealing machine. Background Art

[0002] With the improvement of people's living standards, wet wipes are increasingly used. Wet wipes are a kind of moist paper towels, and sterilization ingredients are often added to their ingredients. Compared with traditional dry paper towels, wet wipes have better wiping effects and disinfection capabilities, so they are deeply loved by people. In order to ensure the long-term moisturizing of wet wipes, they are sealed and packaged.

[0003] Among them, the "wet wipes bag packaging device" disclosed in the application number "CN202010665127.0" is also an increasingly mature technology, which "comprises a frame, lifting cylinders symmetrically arranged on the upper and lower sides of the frame, a lifting plate arranged on the lifting cylinder away from the end of the frame, and a heat-sealing strip arranged on the lifting plate, and also includes through holes symmetrically arranged on the left and right sides of the frame, a powerful exhaust fan arranged at one end of the through hole close to the heat-sealing strip, an exhaust gas flow buffer mechanism arranged at the end of the through hole away from the heat-sealing strip, and an exhaust gas absorption mechanism arranged below the exhaust gas flow buffer device. Compared with the prior art, the present invention absorbs hydrogen chloride in the fume generated by heat sealing by arranging an exhaust gas flow buffer mechanism and an exhaust gas absorption mechanism, thereby improving the absorption effect of hydrogen chloride, reducing strong irritation to the eyes and respiratory mucosa, and ensuring the health of the staff." However, this type of packaging device still has the following defects in actual use:

[0004] In the existing technology, the wet wipes packaging equipment seals the wet wipes packaging bag mouth manually through professional sealing tools.

[0038] The feeding and leveling mechanism 3 is fixedly connected to the leveling frame 301 at the top of the support part 1, and connecting grooves 302 are provided on both sides of the top of the leveling frame 301, and symmetrical connecting blocks 303 are connected inside the two connecting grooves 302, and a rotating shaft is provided on the wall between the symmetrical connecting blocks 303, and a leveling wheel 304 is movably connected to the outer side of the rotating shaft, and slots 305 are provided on both sides of the middle part of the leveling frame 301, and mounting blocks 306 are engaged inside the slots 305, and a leveling pressing cylinder 307 is movably connected between the mounting blocks 306, one end of the leveling pressing cylinder 307 is transmission-connected to the transmission end of the side transmission motor 308 of the leveling frame 301, and a leveling piece 309 is fixedly connected to the side of the top discharge end of the leveling frame 301.

[0039] During specific use, the sealing plastic film is flattened by the provided material feeding and leveling mechanism 3 to avoid wrinkles during the sealing of the wet wipes packaging bag, which affects the sealing of the wet wipes packaging bag. The rotation of the provided transmission motor 308 drives the leveling and pressing cylinder 307 to rotate, so that the leveling and pressing cylinder 307 can seal the sealing film material during the rotation process. The connection blocks 303 inside the connecting grooves 302 at both ends of the leveling frame 301 are installed and engaged, so that the leveling wheels 304 on the symmetrical rotating shafts rotate, which facilitates the transportation of the sealing plastic film to the bottom of the sealing mechanism 4 for sealing.

[0040] The sealing mechanism 4 includes a sealing frame 401 fixedly connected to the top of the bearing part 101, the top of the sealing frame 401 is fixedly connected to a fixed top seat 402, the top of the fixed top seat 402 is fixedly connected to a control rod 4021, the telescopic end of the control rod 4021 is inserted and fixedly connected to a fixed plate 4022, the top sides of the fixed plate 4022 are inserted and connected to guide rods 403, the bottom end of the guide rod 403 is fixedly connected to a fixed frame 404, the top of the fixed frame 404 is fixedly connected to a high-temperature heater 405, and the bottom of the high-temperature heater 405 can form a The four corners of the fixed frame 404 are fixedly connected with inserted screws 406, the top rod column of the inserted screw 406 is inserted and connected with the fixed top seat 402, and the outer side of the inserted screw 406 is sleeved with a return spring 407, and the two sides of the bottom end of the sealing frame 401 are fixedly connected with fixed connecting plates 408, and the top side of each fixed connecting plate 408 is provided with a sliding groove 409, and the inside of the sliding groove 409 is slidably connected with a placement plate 4091, the top of the placement plate 4091 is provided with a placement groove, and the bottom of the placement plate 4091 is provided with an electric rod 4092.

[0041] When the wet wipes packaging bag is sealed, when the plastic packaging film passes through the sealing frame 401, the control rod 4021 at the bottom of the fixed top seat 402 is extended and retracted to facilitate the fixed frame 404 set at the bottom of the fixed plate 4022 to move downward on the Z axis, so that the high-temperature heater 405 installed on the fixed frame 404 is attached to the sealing part of the packaging bag. The heat generated by the high-temperature heater 405 makes the sealing plastic film passing through the sealing part of the packaging bag to be attached at high temperature, and the "mouth"-shaped high-temperature heater 405 is used to heat the wet wipes packaging bag. High-temperature lamination is performed to facilitate the high-temperature sealing of the sealing plastic film on the wet wipes packaging bag. When sealing, in order to facilitate the placement of the wet wipes packaging bag before and after sealing, the electric rod 4092 is extended and retracted to facilitate pushing the placement plate 4091 in the slide groove 409 on the fixed connecting plate 408 to move back and forth at the bottom of the high-temperature heater 405, which is convenient for loading or unloading. The two elastic mold assemblies are arranged to facilitate the ejection and unloading of the wet wipes packaging bag placed in the placement groove.

[0042] The laminating mechanism 5 includes a laminating frame 501 fixedly connected to the top discharge end of the bearing part 101, a mounting frame 502 fixedly connected to one side of the feeding end of the laminating frame 501, a working motor 503 fixedly connected to one side of the mounting frame 502, a driving end of the working motor 503 fixedly connected to a feed shaft 504, a feeding rack 505 is arranged on the outer side of the feed shaft 504, a movable rod 506 is fixedly connected to the top of one side of the laminating frame 501, a pressing cylinder 5061 is movably connected to the telescopic end of the movable rod 506, two telescopic rods 507 are fixedly connected to the top of the laminating frame 501, and a laminating pressing plate 508 is fixedly connected to the telescopic end of the two telescopic rods 507, and a unwinding cylinder 509 is arranged on the top of the sealing frame 401.

The rotation of the feed rack 505 facilitates the pushing of the sealed wet wipes packaging bag on the sealing mechanism 4 to the bottom end of the coating pressing plate 508. The expansion and contraction of the movable rod 506 drives the pressing cylinder 5061 to press the sealed wet wipes packaging bag to be covered with a layer of transparent dust-proof film.

[0046] Example 2

[0047] Based on the above-mentioned embodiment 1, although the wrinkle problem of the wet wipes packaging bag during sealing and packaging is solved, at the same time, since the wet wipes are not in a unique position during the sealing and packaging process, the sealing failure problem is easy to occur during the sealing welding. At the same time, in the process of sealing the wet wipes packaging bag by heating, the waste smoke generated is easy to cause harm to the environment and users, and when the smoke is absorbed, there may be a situation where the smoke cannot be completely absorbed due to the deviation of the welding position. In view of the above problems, the following solutions are proposed.

[0048] like Figure 8-Figure 9As shown, a plurality of smoking grooves 4011 are provided on the sealing frames 401 on both sides. In the present embodiment, there are four smoking grooves 4011, and the openings of the four smoking grooves 4011 are evenly distributed in the welding area of ​​the sealed packaging bag, and a filter 4012 is fixedly provided in the smoking groove 4011, through which the fume generated during welding is preliminarily filtered to reduce the degree of fume pollution.

[0049] At the same time, a partition is connected to the opening of each smoking groove 4011, and the switch of the partition can be controlled by the extension and shortening of the control rod 4021, that is, when the control rod 4021 is extended, the smoking groove 4011 is in an open state, and when the control rod 4021 is shortened, the smoking groove 4011 is closed by the partition. It should be noted that in this solution, the smoking mode of the smoking groove 4011 is preferably a negative pressure mode to ensure that the smoke within the range can be effectively adsorbed.

[0050] However, when the wet wipes are sealed and packaged, the position of the wet wipes will deviate due to the long time. At this time, the smoke content absorbed in the four smoking grooves 4011 will be obviously different. That is, the deviation position of the wet wipes can be determined according to the smoke distribution in the smoking groove 4011, which is convenient for fine-tuning the welding position of the high-temperature heater 405.

[0051] At the same time, in order to ensure that during the welding process, the sealing welding of the wet wipes can be completed between the heating blocks 4051, and there will be no welding deviation when the position of the wet wipes is offset, a pressure spring is fixedly provided between the fixed frame 404 and the high-temperature heater 405. At the same time, in the present embodiment, the fixed frame 404 and the high-temperature heater 405 are connected by a ball joint, that is, when the high-temperature heater 405 on one side first contacts the wet wipes, the pressure spring at this position will be subjected to force before the high-temperature heater 405 on the other side. This means that the position of the wet wipes has deviated and corresponding adjustments need to be made. When the control rod 4021 is not extended to the welding length, the pressure springs on both sides are subjected to force at the same time, and the positions of the wet wipes on both sides need to be adjusted synchronously.

[0052] It should be noted that when the pressure spring is first subjected to force, the control rod 4021 stops extending, driving the high-temperature heater 405 to separate from the wet wipes to avoid damage to the wet wipes, and the high-temperature heater 405 is always in a horizontal state when not subjected to force.

[0053] One end of the high-temperature heater 405 is movably provided with four heating blocks 4051, and the ends of the four heating blocks 4051 that are separated from each other are respectively connected with moving rods 4052, and the distance between the four heating blocks 4051 is controlled by the moving rods 4052, and the four heating blocks 4051 can form a "mouth" shape. Initially, the area of ​​the "mouth" shape formed by the four heating blocks 4051 is larger than the area of ​​the wet wipes, ensuring that the wet wipes can always be located between the four heating blocks 4051, and the position of the wet wipes and the position of the sealing welding can be adjusted by adjusting the four heating blocks 4051, and the four corners of the fixed frame 404 are fixedly connected with interlaced screws 406, and the top rod column of the interlaced screw 406 is interlaced with the fixed top seat 402, and cooperates with the reset spring 407 connected by the interlaced screw 406. At the same time, the elongation length of the control rod 4021 can be monitored according to the elastic change of the reset spring 407, and The mutual cooperation between 7 and the pressure spring, that is, the normal working process between the reset spring 407 and the pressure spring is that under the extension of the control rod 4021, the high-temperature heater 405 is driven to move to a position close to the wet wipes. At this time, the deformation of the pressure spring remains unchanged, and the compression of the reset spring 407 increases. When the high-temperature heater 405 contacts the film at the edge of the wet wipes, the pressure spring begins to deform, and the compression of the reset spring 407 slowly increases. After welding is completed, the reset spring 407 and the pressure spring stop compressing at the same time to reset the compression length. However, when the high-temperature heater 405 first contacts the wet wipes, the compression of the reset spring 407 is still in a relatively fast compression stage, and the pressure spring is stressed, which means that there is a maintenance deviation between the high-temperature heater 405 and the wet wipes, and the direction of the instantaneous force on the pressure spring is compared with the change in the compression of the reset spring 407, thereby determining the adjustment angle of the heating block 4051 to the wet wipes position.

[0054] It should be noted that in order to prevent the high-temperature heater 405 from damaging the wet wipes with position deviation during movement, when the return spring 407 is at a faster compression speed, the high-temperature heater 405 is in a preheating state, and the temperature of the high-temperature heater 405 at this time will not cause damage to the wet wipes.

[0055] Each smoking slot 4011 is connected to a smoke sensor. By analyzing the smoke concentration in each smoking slot 4011, on the one hand, the position of the high-temperature heater 405 during welding of the wet wipes sealing package can be determined. On the other hand, the degree of heat generated by the high-temperature heater 405 during welding can be detected, and the welding temperature of the high-temperature heater 405 can meet the sealing welding requirements.

[0056] Initially, the moving rod 4052 is in a shortened state, the control rod 4021 is in a shortened state, the heating block 4051 is not heated, and the return spring 407 and the pressure spring are both in a normal state.

[0057] During operation, after the wet wipes are moved onto the placement plate 4091, the control rod 4021 is extended, driving the high-temperature heater 405 to move toward a position close to the wet wipes. At the same time, the length of the reset spring 407 is compressed, and during the extension of the control rod 4021, the heating block 4051 on the high-temperature heater 405 is preheated, and during the preheating of the heating block 4051, the length of the moving rod 4052 is extended, controlling the four heating blocks 4051 to move toward one side closer to each other, and the four heating blocks 4051 conflict with each other, ensuring that the heating blocks 4051 can perform sealing welding on the edges of the wet wipes.

[0058] As the device is used, when the position of the wet wipes on the placement plate 4091 deviates, as the control rod 4021 extends, the heating block 4051 first collides with one side of the wet wipes, causing the high-temperature heater 405 to deflect on the wet wipes, driving the pressure spring on one side to compress. At the same time, when the compression value between the reset spring 407 does not reach the set value, the pressure spring is forced to adjust the control rod 4021 to stop extending, and at the same time, the angle between the reset spring 407 and the compressed pressure spring is recorded. After recording, the control rod 4021 is shortened, so that the heating block 4051 is separated from the wet wipes, ensuring that the high-temperature heater 405 returns to a horizontal state. At the same time, the angle difference between the reset spring 407 and the pressure spring is used to facilitate the determination of the position of the wet wipes on the placement plate 4091.

[0059] According to the positioning between the reset spring 407 and the pressure spring, the position of the wet wipes is ensured, and at the same time, the moving rod 4052 is controlled to redistribute the position of the heating block 4051, so that the four heating blocks 4051 cover the position of the wet wipes. After the control rod 4021 is extended, the heating block 4051 directly seals and welds the wet wipes that are displaced in position, and when the reset spring 407 is compressed to one third, the partition opens, so that the smoke extraction slot 4011 can absorb the smoke generated by welding, and the smoke content in the smoke extraction slot 4011 is identified by each smoke sensor. At the same time, when the control rod 4021 is shortened after welding, the smoke sensor in the smoke extraction slot 4011 does not identify that there is smoke passing. At this time, the negative pressure of the smoke extraction slot 4011 is controlled to increase through the smoke sensor, so as to improve the ability to absorb smoke and avoid smoke overflow.

[0060] When the wet wipes are in a normal welding position, the smoke sensor recognizes that the amount of smoke from the two middle positions of the smoke extraction slots 4011 is larger than that from the two sides, and the amount of smoke from the two middle positions of the smoke extraction slots 4011 is basically the same. At this time, the smoke extraction slots 4011 are in a normal negative pressure state; when the positions of the four heating blocks 4051 move compared to the normal welding state, it means that the position of the wet wipes is offset. At this time, the distance problem between the smoke extraction slots 4011 used for welding with wet wipes causes the smoke extraction slots 4011 to be unable to absorb the smoke generated during welding or the absorption amount is small when the control rod 4021 is shortened. That is, the smoke sensor cannot recognize that smoke is passing by, and then the negative pressure of the smoke extraction slot 4011 is controlled by the smoke sensor to increase, thereby improving the ability to capture smoke from a farther distance.

[0061] At the same time, since a film is easily attached to the high-temperature heater 405 during the welding process, affecting the sealing tightness of the heating block 4051 when sealing the wet wipes, in order to determine whether a film is attached to the high-temperature heater 405 during welding, the heating block 4051 is preheated during the extension of the control rod 4021, and when the return spring 407 is compressed to one-third during the continuous feeding of the control rod 4021, the smoking slot 4011 is opened to absorb the external gas. When there is no film attached to the heating block 4051, At this time, as the heating block 4051 is heated, the smoke sensor in the smoking groove 4011 will not recognize the amount of smoke; when a film is attached to the heating block 4051, the heating of the heating block 4051 will cause smoke to be generated from the film on the heating block 4051, and at the same time, it will be adsorbed by the smoking groove 4011 and recognized by the smoke sensor. At the same time, the reset spring 407 and the pressure spring have not reached the target depth, so that the control rod 4021 stops extending, prompting the staff to remove the debris on the heating block 4051 and then perform the sealing work.

[0062] By setting up the smoke extraction slot 4011, the smoke sensor and the heating block 4051, when the welding position of the wet wipes deviates, the welding of the wet wipes can still be achieved by changing the distribution position of the heating block 4051, and in the process of welding, the smoke at different positions in each welding state is absorbed by the negative pressure change of the smoke extraction slot 4011. At the same time, before the heating block 4051 is ready for welding, the mutual cooperation between the smoke extraction slot 4011 and the smoke sensor can realize the judgment whether there is film residue attached to the heating block 4051.
