Description

Technical Field

[0001] The invention relates to the technical field of asphalt film bag processing, and in particular to asphalt film bag production equipment. Background Art

[0002] There are three main types of asphalt: coal tar asphalt, petroleum asphalt and natural asphalt. The vast majority of asphalt used in engineering projects is petroleum asphalt, which is the residue after crude oil distillation. Depending on the degree of refining, it is liquid, semi-solid or solid at room temperature.

[0003] The material and structure of asphalt packaging bags are constantly changing with different uses and packaging materials. The earliest asphalt packaging bags were made of multiple layers of kraft paper, which were eliminated due to their low mechanical strength, easy to break, squeeze leakage, and difficult material peeling. Since the 1990s, many improvements have been made to asphalt packaging bags at home and abroad. Some use glue to bond woven mesh between multiple layers of kraft paper and apply organic film on the inner layer to enhance the mechanical strength of the packaging bag and solve the problem of easy material peeling; some use modified polypropylene to make asphalt soft packaging bags; some are made of plastic woven outer layer and plastic film inner layer.

[0004] In the prior art, when the processing equipment for this type of inner and outer double-layer asphalt packaging bags is in use, the pre-processing of the inner film bags and the combination of the finished outer film bags and the inner film bags are processed separately. The inner film bags are first processed in batches, and then the pre-processed inner film bags are transferred to a separate processing table. Then, the finished outer film bags, which are slightly larger in volume than the inner film bags, are put on the inner film bags to complete the combination of the inner and outer film bags. However, this processing method requires a lot of time to transport the pre-processed inner film bags, and therefore affects the processing efficiency of the entire inner and outer double-layer asphalt packaging bags.

[0037] An embodiment of the present invention provides an asphalt film bag production device, including an assembly frame 1 and a PLC control system, a first processing table 2 is provided at the side end of the assembly frame 1, a first conveyor 3 and a second conveyor 4 are provided on the assembly frame 1 above the first processing table 2, a packaging bag slitting machine 5 is provided between the first conveyor 3 and the second conveyor 4, a material shaft 6 is provided on the right side of the first conveyor 3, a second processing table 7 is provided below the first processing table 2, a material baffle plate 8 is provided on the assembly frame 1 at the same end of the first processing table 2 and the second processing table 7, a first bag expanding component 9 is provided on the first processing table 2 near the material baffle plate 8, a second bag expanding component 10 is provided on the second processing table 7 near the material baffle plate 8, a third bag expanding component 11 is provided on the right side of the second bag expanding component 10, and a A third conveyor 12 and a fourth conveyor 13 are respectively provided on both sides of the material baffle plate 8, a through slot 81 is provided on the material baffle plate 8, a pushing assembly 14 is provided on the outer side of the material baffle plate 8, and one end of the pushing assembly 14 can pass through the through slot 81 and extend to the position of the second processing table 7, a photoelectric sensor 15 is provided on the side end of the first bag expansion assembly 9, and the first conveyor 3, the second conveyor 4, the third conveyor 12, the fourth conveyor 13, the packaging bag slitting machine 5, the first bag expansion assembly 9, the second bag expansion assembly 10, the third bag expansion assembly 11 and the photoelectric sensor 15 are all electrically connected to the PLC control system; an automatic sprayer 16 is provided on the assembly frame 1, and the automatic sprayer 16 is located on the left side of the first bag expansion assembly 9, and the interior of the automatic sprayer 16 is filled with glue that promotes the inner sides of the inner film bag opening to adhere to each other;

[0038] Before processing, the inner film bag coil to be processed is installed on the material shaft 6. The inner film bag coil is composed of multiple inner film bags wound together in sequence. The multiple inner film bags are connected in sequence head to tail. Both sides of each inner film bag are sealed, and the front and rear openings of each inner film bag are not sealed.

[0039] The inner film bag at the outermost part of the inner film bag reel is pulled against the surface of the first processing table 2 toward the material blocking plate 8, and the inner film bag passes through the first conveyor 3, the packaging bag slitting machine 5 and the second conveyor 4 in sequence, and the PLC control system is controlled to start the first conveyor 3 and the second conveyor 4 to convey the inner film bag to the first bag expansion component 9. When the photoelectric sensor 15 detects the inner film bag, the first conveyor 3 and the second conveyor 4 are suspended. At this time, the front end opening of the inner film bag is just kept in the corresponding position with the first bag expansion component 9;

[0040] The packaging bag slitting machine 5 is started to cut the inner film bag on the first processing table 2, and then the first bag expanding component 9 is used to open the front end opening of the cut inner film bag, and the automatic spraying machine 16 sprays glue on the inner wall of the front end opening of the inner film bag;

[0041] The first bag expansion component 9 performs hot-melt sealing on the outside of the front end opening of the inner membrane bag, and then the second conveyor 4 continues to convey the inner membrane bag forward. During the movement, the front end sealing part of the inner membrane bag will gradually separate from the first processing table 2 and come into contact with the material blocking plate 8. Since the first processing table 2 loses its supporting effect on the front end part of the inner membrane bag, the front end part of the inner membrane bag will tilt downward under the action of its own gravity and droop along the surface of the material blocking plate 8 to the horizontal position of the through groove 81. At this time, the second conveyor 4 stops running, and the first bag expansion component 9 clamps the part of the inner membrane bag close to the unsealed part, and controls the inner membrane bag instead of the second conveyor 4;

[0042] One end of the pushing component 14 gradually passes through the through slot 81 and pushes the front sealing portion of the inner film bag toward the third conveyor 12. At this time, the inner film bag completes a flip. At the same time, the sealed portion of the inner film bag switches from the original direction toward the baffle plate 8 to the direction toward the third conveyor 12.

[0043] Subsequently, the third conveyor 12 continues to convey the inner membrane bag to the fourth conveyor 13 for a distance. When the unsealed opening of the inner membrane bag is at the position of the second bag expansion component 10, the third conveyor 12 stops running, and the second bag expansion component 10 opens the unsealed opening of the inner membrane bag, and the pushing component 14 continues to run. At this time, one end of the pushing component 14 gradually extends from the unsealed opening of the inner membrane bag to the inner area of ​​the inner membrane bag until one end of the pushing component 14 is inserted into the inner area of ​​the entire inner membrane bag.

[0044] The finished outer film bag, which is slightly larger in volume than the inner film bag, is laid flat on the second processing table 7, which has the same structure as the pre-processed inner film bag. At the same time, the unsealed opening of the outer film bag is oriented toward the baffle plate 8 and is located at the third bag expansion component 11. The third bag expansion component 11 is started to open the unsealed opening of the outer film bag.

[0045] The pushing component 14 continues to operate and extends the inner membrane bag from the unsealed opening of the outer membrane bag into the interior thereof until the bottom end of the inner membrane bag is completely in contact with the inner bottom of the outer membrane bag. Meanwhile, during the operation of the pushing component 14, the second bag expanding component 10 stops controlling the inner membrane bag. After the inner membrane bag and the outer membrane bag are completely combined, the third bag expanding component 11 starts to operate and performs hot-melt processing on the bag opening of the outer membrane bag, so that the outer membrane bag and the unsealed opening of the inner membrane bag are sealed together. Subsequently, the pushing component 14 detaches from the inner membrane bag and returns to its original position.

[0046] At this time, the inner film bag and the outer film bag are combined, and then the fourth conveyor 13 conveys the combined inner film bag and the outer film bag to the rear side of the second processing table 7 and completes the unloading;

[0047] By repeating the above steps repeatedly, the automated inner film bag processing of the inner and outer double-layer asphalt packaging bags and the combination of the inner film bag and the outer film bag can be completed. There is no need to independently process the inner film bag and the combination of the inner film bag and the outer film bag, thus saving the transportation time of the inner film bag and realizing the integrated inner and outer double-layer asphalt packaging bag processing flow.

[0048] Preferably, the first conveyor 3, the second conveyor 4, the third conveyor 12 and the fourth conveyor 13 have the same structure and all include a conveying roller 31 and a driving mechanism 32 that can drive the conveying roller 31 to rotate, the driving mechanism 32 is installed on the assembly frame 1, the conveying roller 31 is horizontally placed on the corresponding first processing table 2 and the second processing table 7, the conveying roller 31 can rotate on the assembly frame 1, and the extending end of the conveying roller 31 passes through the assembly frame 1 and is connected to the output end of the driving mechanism 32. The control of the driving mechanism 32 by the PLC control system can enable the corresponding conveying roller 31 to convey the inner membrane bag and the outer membrane bag on the first processing table 2 and the second processing table 7 respectively, and cooperate with the first bag expansion component 9, the second bag expansion component 10 and the third bag expansion component 11 to pre-process the inner membrane bag and perform combined processing of the inner membrane bag and the outer membrane bag.

[0049] Preferably, the first bag expansion assembly 9, the second bag expansion assembly 10 and the third bag expansion assembly 11 have the same structure and all include a lifting module 91, a fixed plate 92 and two support plates 93. The fixed plate 92 is vertically arranged on the first processing table 2 and the second processing table 7. The lifting module 91 is provided with two, and the two lifting modules 91 are respectively installed on the fixed plate 92 and the assembly frame 1, and the two lifting modules 91 are symmetrically arranged, one of the support plates 93 is horizontally placed between the two lifting modules 91, and the two ends of the support plate 93 are respectively connected to the output ends of the two lifting modules 91, and the other support plate 93 is arranged on the corresponding first processing table 2 and the second processing table 7, and the two support plates 93 are symmetrically arranged, each support plate 93 is provided with an adsorption module 94 and a hot pressing strip 95, and the assembly frame 1 is provided with a negative pressure device matching each adsorption module 94, and each of the adsorption modules 94 is connected to the matching negative pressure device , the assembly frame 1 is also provided with a heating device matched with each hot pressure strip 95, and each hot pressure strip 95 is connected to the matching heating device. After the adsorption modules 94 on the two support plates 93 are adsorbed from the upper and lower sides of the inner membrane bag and the outer membrane bag respectively, the two lifting modules 91 drive one of the corresponding support plates 93 to rise. At this time, the upper and lower sides of the unsealed opening parts of the inner membrane bag and the outer membrane bag will gradually separate and be converted into an open state. At the same time, the adsorption module 94 can keep the opening parts of the inner membrane bag and the outer membrane bag always in an open state during operation, so as to facilitate the extension of the pushing component 14 into the interior of the inner membrane bag and the inner membrane bag into the interior of the outer membrane bag, and the opening part is opened by adsorbing the outside of the inner membrane bag and the outer membrane bag, which can effectively avoid the wear on the surface of the bag body when the inner membrane bag or the outer membrane bag is controlled by the clamping claws or other clamping methods in the prior art;

[0050] When the two lifting modules 91 drive the corresponding support plates 93 to descend, the heating device can be started to conduct heat to each hot pressure strip 95, so that the hot pressure strips 95 on the two support plates 93 can be hot-melt sealed from the opening parts of the inner film bag and the outer film bag, so that the inner film bag can form a sealed combination that can accommodate asphalt and the opening parts of the inner film bag and the outer film bag.

[0051] Preferably, the pushing assembly 14 includes a pushing frame 141, an electric telescopic rod 142 and a pushing plate 143, wherein the pushing frame 141 is located on the outside of the baffle plate 8, the pushing plate 143 is located above the pushing frame 141, and the pushing plate 143 can pass through the through slot 81 on the baffle plate 8, the electric telescopic rod 142 is installed on the pushing frame 141, and the output end of the electric telescopic rod 142 is connected to the rear side of the pushing plate 143, and the electric telescopic rod 142 can drive the pushing plate 143 from the pushing frame 141 to the rear side of the pushing frame 141. The baffle plate 8 moves, and when the front end of the pre-processed inner membrane bag hangs down to the through groove 81 of the baffle plate 8, the front end of the inner membrane bag can be pushed toward the third conveyor 12 by the pushing action of the push plate 143, and the inner membrane bag can be turned over in cooperation with the operation of the third conveyor 12, thereby assisting the inner membrane bag to move from the first processing table 2 to the second processing table 7. In combination with the double-layer design of the first processing table 2 and the second processing table 7, compared with the linear integrated processing table in the prior art, the overall space occupied by this device is smaller;

[0052] When the front end opening of the inner membrane bag is pushed to the third conveyor 12 by the push plate 143, as the third conveyor 12 controls the inner membrane bag to move a certain distance in the direction of the fourth conveyor 13, the rear end opening of the inner membrane bag will fall from the first processing table 2. At this time, the push plate 143 can stay in the pushing state position of the inner membrane bag, and the extended push plate 143 can form a supporting effect on the rear end opening of the inner membrane bag and the lower part of the inner membrane bag to prevent the unsealed opening of the inner membrane bag from contacting the ground and causing wear after the inner membrane bag is turned over.

[0053] Preferably, a cavity is provided inside the push plate 143, and multiple air vents 144 are provided on the upper and lower sides of the push plate 143. An air inlet 145 is also provided on the rear side of the push plate 143. The air inlet 145 is communicated with the multiple air vents 144 and the internal cavity of the push plate 143. An air supply device is also provided on the push frame 141, and the output end of the air supply device is connected with the air inlet 145 of the push plate 143 through an air pipe. When the push plate 143 extends the inner film bag into the outer film bag, the air supply device can be started to supply air to the internal cavity area of ​​the push plate 143 through the air pipe. As the air flow is gradually discharged from the multiple air vents 144 on the push plate 143, the air flow will form a certain thrust on the upper and lower layers inside the inner film bag. By filling the inner film bag with gas, the outer surface of the inner film bag can be kept in contact with the internal area of ​​the outer film bag as much as possible, thereby improving the fit between the inner film bag and the outer film bag after combination and the quality of the inner and outer double-layer asphalt packaging bags.

[0054] Preferably, the baffle plate 8 is arc-shaped. As the pre-processed inner membrane bag moves from the first processing table 2 to the baffle plate 8, the front end of the inner membrane bag will first bend downward at a certain angle along the arc-shaped portion of the baffle plate 8 to prevent the front end of the inner membrane bag from warping up. At the same time, combined with the gravity of the inner membrane bag itself, the front end of the inner membrane bag can smoothly droop to the through groove 81, thereby cooperating with the pushing action of the push plate 143 to flip the inner membrane bag.
