Description

Technical Field

[0001] The present application relates to the technical field of unpacking, and in particular to a continuous unpacking device. Background Art

[0002] A package opener is a device that opens the outer packaging of materials. It usually uses a cutting knife to cut the outer packaging and separates the materials from the outer packaging by dumping.

[0003] However, for continuously bagged materials, conveyor lines are usually used for transmission, and it is impossible to separate them from the outer packaging by dumping. Therefore, conventional unpacking machines have poor unpacking effects on continuously bagged materials, and when the cutter is maintained, the machine needs to be shut down, which affects the unpacking efficiency and further affects the previous and subsequent processes, causing the entire process to be interrupted, resulting in low production efficiency and stability. Utility Model Content

[0004] The purpose of this application is to solve the problem of low unpacking efficiency and effectiveness of continuously bagged materials in the prior art. Therefore, this application provides a continuous unpacking device. Through the cooperation of the cutting blade of the unpacking unit, the upper and lower film rolling devices and the conveyor line, the unpacking effect of continuously bagged materials is improved. The multiple unpacking units can be replaced to ensure unpacking efficiency and reliability. At the same time, the flattening unit before unpacking can achieve material flattening, further improving the reliability of unpacking.

[0005] The embodiment of the present application provides a continuous unpacking device for unpacking continuously bagged materials, comprising a flattening unit and a plurality of unpacking units;

[0006] The flattening unit includes a first conveying line and a pressing member, wherein the pressing member is arranged above the first conveying line and is used to flatten the material on the first conveying line;

[0007] The multiple unpacking units are sequentially arranged along the conveying direction, and the unpacking unit located at the front end of the multiple unpacking units is arranged corresponding to the discharge port of the flattening unit; the unpacking unit includes a second conveying line and a cutting assembly and a film rolling assembly sequentially arranged along the conveying direction of the second conveying line;

[0008] The cutting assembly includes two cutting knives respectively arranged on the left and right sides of the second conveying line, and the cutting knives are used to cut the packaging bag of the material from the side of the material, so that the packaging bag of the material forms an upper film and a lower film;

[0009] The film rolling assembly includes an upper film rolling device and a lower film rolling device respectively arranged on the upper and lower sides of the second conveyor line. The upper film rolling device is used to roll up the upper film, and the lower film rolling device is used to roll up the lower film.

[0010] By adopting the above technical solution, the second conveyor line, the cutting knives on both sides and the upper and lower film rolling equipment cooperate to realize the synchronous continuous disassembly and continuous rewinding of the packaging bags during the transmission of the continuous bagged materials, thereby realizing complete unpacking and improving the unpacking effect; and, through the cooperation of the first conveyor line and the pressure piece, the continuous bagged materials can be leveled before unpacking, that is, the upper and lower films can be leveled, so that the subsequent cutting knives can be aligned with the preset position of the packaging bag for disassembly, so that the upper and lower films can be divided in a preset shape, thereby facilitating the subsequent rewinding and improving the unpacking reliability; at the same time, redundant backup is achieved through multiple unpacking units, and replaceable operations are achieved, so that the need to shut down a single unpacking unit for maintenance is avoided, and continuous and reliable unpacking is realized, thereby ensuring unpacking efficiency and reliability.

[0011] In some embodiments, the cutting assembly of the unpacking unit located at the front end of the plurality of unpacking units is disposed near the end of the first conveying line;

[0012] The cutting assembly of the adjacent unpacking unit is arranged close to the end of the second conveying line of the previous unpacking unit.

[0013] By adopting the above technical solution, the upper and lower films formed by cutting can be quickly connected to the corresponding film rolling equipment through the connecting gap between the conveyor lines, thereby improving the unpacking efficiency.

[0014] In some embodiments, there are two of the plurality of unpacking units.

[0015] In some embodiments, the pressing member is a third conveying line inclined toward the end of the first conveying line;

[0016] The third conveying line and the first conveying line jointly clamp the material and convey it toward the unpacking unit.

[0017] By adopting the above technical solution, leveling is achieved while reducing the impact on the efficiency of continuous bag material transportation.

[0018] In some embodiments, the driving wheel of the first conveyor line and the driving wheel of the third conveyor line are both arranged close to the unpacking unit, and the driving wheel of the first conveyor line and the driving wheel of the third conveyor line are arranged opposite to each other in the vertical direction.

[0019] The above technical solution improves the transmission reliability of continuous bagged materials when subjected to cutter resistance.

[0020] In some embodiments, the cutting knife is retractable to move closer to or farther away from the material on the first conveying line or the second conveying line.

[0021] The above technical solution makes it easier for the cutter to adjust the cutting depth according to different cutting requirements and facilitates the maintenance of the cutter.

[0039] See Figure 1 , Figure 1 This is a structural diagram of an embodiment of the present application.

[0040] The present application provides a continuous unpacking device, particularly suitable for unpacking continuously bagged materials. Continuously bagged materials refer to materials of a certain length that, in particular, can be continuously produced along the length through a previous process, resulting in a continuous flow of bagged materials. Unpacking of such materials must be coordinated with the production process rhythm, meaning that continuous uninterrupted unpacking must be performed simultaneously with continuous uninterrupted production.

[0041] The device includes a flattening unit 100 and a plurality of unpacking units 200 connected in sequence.

[0042] In one embodiment, the flattening unit 100 includes a first conveying line 110 and a pressing member 120 .

[0043] The pressing member 120 is disposed above the first conveyor line 110 and is used to flatten the material on the first conveyor line 110, thereby flattening the continuously bagged material before unpacking. This flattens the material from top to bottom, facilitating the subsequent cutting blade 220 to align with the preset position of the packaging bag for unpacking. This allows the upper and lower films 3 to be separated in a preset configuration, facilitating subsequent rewinding and improving unpacking reliability. Typically, the cutting blade 220 of the unpacking unit 200 cuts the bag at the center seam.

[0044] In one embodiment, the pressure member 120 is a third conveyor line inclined toward the end of the first conveyor line 110. The third conveyor line and the first conveyor line 110 jointly clamp and convey the material toward the unpacking unit 200, thereby achieving leveling while reducing the impact on the continuous bagging material conveying efficiency.

[0045] In one embodiment, the driving wheel of the first conveyor line 110 and the driving wheel of the third conveyor line are both arranged close to the unpacking unit 200, and the driving wheel of the first conveyor line 110 and the driving wheel of the third conveyor line are arranged relative to each other in the vertical direction, thereby improving the reliability of maintaining the transmission of continuous bagged materials when encountering resistance from the cutting knife 220.

[0046] In one embodiment, multiple unpacking units 200 are sequentially arranged along the conveying direction to achieve redundancy and interchangeable operation, thereby avoiding the need to shut down a single unpacking unit 200 for maintenance. Continuous and reliable unpacking can be achieved through another unpacking unit 200, thereby ensuring unpacking efficiency and reliability. In one specific embodiment, two of the multiple unpacking units 200 are provided.

[0047] In one embodiment, the unpacking unit 200 located at the front end of the multiple unpacking units 200 is arranged to correspond to the discharge port of the flattening unit 100.

[0048] In one embodiment, the unpacking unit 200 includes a second conveyor line 210 and a cutting assembly and a film roll assembly sequentially arranged along the conveying direction of the second conveyor line 210. The cutting assembly is used to cut the packaging bags, and the film roll assembly collects the cut packaging bags to form a film roll 1.

[0049] The cutting assembly includes two cutters 220 respectively arranged on the left and right sides of the second conveyor line 210. The cutters 220 are used to cut the packaging bag of the material from the side of the material and form the upper film 2 and the lower film 3 of the packaging bag of the material.

[0050] The film rolling assembly includes an upper film rolling device 230 and a lower film rolling device 240 respectively arranged on the upper and lower sides of the second conveyor line 210. The upper film rolling device 230 is used to roll up the upper film 2, and the lower film rolling device 240 is used to roll up the lower film 3.

[0051] This method, through the cooperation of the second conveyor line 210, the cutting blades 220 on both sides, and the upper and lower film rolling devices 240, realizes the continuous unpacking and continuous rewinding of the packaging bags during the transportation of the continuously bagged materials, achieving complete unpacking and improving the unpacking effect. In addition, the method of cutting into upper and lower films 3 facilitates the upper and lower installation of the film rolling devices, improving space utilization.

[0052] In one embodiment, the cutter 220 is retractable to move closer to or further away from the material on the first conveyor line 110 or the second conveyor line 210 , so that the cutter 220 can adjust the cutting depth according to different cutting requirements and can be maintained.

[0053] In one embodiment, the cutting assembly of the forward-most unpacking unit 200 among the multiple unpacking units 200 is positioned near the end of the first conveyor line 110. The cutting assembly of the adjacent unpacking unit 200 is positioned near the end of the second conveyor line 210 of the preceding unpacking unit 200. This arrangement facilitates the rapid connection of the cut upper and lower films 3 to their respective film winding equipment through the connecting gaps between the conveyor lines, thereby improving unpacking efficiency.

[0054] In one embodiment, the film rolling device 230 includes a film roll fixing member 232 , a driving member 233 and an abutting member 234 .

[0055] The film roll fixing member 232 is used to connect the film reel, which is usually used to provide a central shaft for winding the film into a roll, and different film reels can be selected according to the winding amount and film type.

[0056] The driving member 233 is connected to the abutment member 234, and the abutment member 234 is used to keep the surface of the film roll on the film roll fixing member 232 in contact with the film roll. The film roll on the film roll fixing member 232 rotates and reels the upper film 2 under the drive of the driving member 233, that is, the driving member 233 directly drives the film roll to rotate and rewind. Compared with the conventional method of driving the film roll to rotate through the film roll fixing member 232, it can be directly adapted to different types of film rolls, has high versatility, and effectively controls costs.

[0057] It should be noted that conventional film roll holders 232 with unwinding functions, such as unwinding shafts, need to have a diameter that closely matches the inner diameter of the film roll, and are typically provided with a limit mechanism at the ends to restrict the ends of the film roll. One end of the unwinding shaft is connected to the drive motor via transmission gears, resulting in a complex structure. Furthermore, the limit mechanism needs to be unlocked when installing the film roll, making operation inconvenient. However, the present application directly drives the film roll via the drive member 233. Therefore, the structure of the film roll holder 232 can be relatively simple, for example, only the shaft is installed, and its diameter can be smaller to accommodate film rolls of various inner diameters, with a certain gap between the two.

[0058] Preferably, the driving member 233 is a motorized roller, and the abutting member 234 is a pneumatic rod.

[0059] In one embodiment, the film rolling device 230 further includes a mounting seat 231 .

[0060] The film roll fixing member 232 is disposed on the mounting seat 231 .

[0061] The abutting member 234 is rotatably mounted on the mounting base 231 .

[0062] The driving member 233 is arranged at the end of the abutment member 234 away from the mounting seat 231, and the abutment member 234 is connected to a torsion spring, which applies a torsional force toward the film roll fixing member 232 to the driving member 233, so that the driving member 233 has a tendency to fit the surface of the film roll shaft on the film roll fixing member 232, thereby further improving the convenience of operation.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
