Description

Technical Field

[0001] The invention relates to the technical field of container bag production and bag cutting, and in particular to a high-toughness container bag production and bag cutting machine and a use method thereof. Background Art

[0002] Container bags, also known as flexible container bags, ton bags, space bags, etc., are a type of container unit equipment. Equipped with a crane or forklift, container unit transportation can be achieved. It is suitable for transporting bulk powder and granular materials. Container bags are a kind of flexible transportation packaging container, widely used in the transportation and packaging of powder, granular, and blocky items such as food, grains, medicines, chemicals, and minerals. When producing container bags, they need to be cut to facilitate sewing. However, the existing cutting device has a poor smoothing effect on the fabric of the container bag when in use. There are a lot of wrinkles on the surface of the fabric of the container bag, which affects the cutting quality.

[0003] For example, the smoothing and shearing equipment for plastic packaging film production provided by the authorization announcement number CN116462041B has two smoothing rollers that are close to each other in the initial state of shearing. Then, the limit handle is turned to make the control shaft rotate relative to each other. Then, with the cooperation of the threaded part, the two smoothing rollers will continue to spread along the upper surface of the plastic packaging film to achieve full smoothing of the plastic packaging film. In addition, the cooperation of the abutment mechanism further ensures the smoothing contact quality between the smoothing roller and the plastic packaging film. Through the mutual cooperation between the set abutment mechanism and the smoothing mechanism, the plastic packaging film can be fully smoothed between cutting to avoid wrinkling and pulling during the cutting process. With the cooperation of the cutting shaft and the shearing mechanism, the rapid shearing of the plastic packaging film is ensured, which is highly practical and reliable.

[0004] It has major drawbacks: the packaging film to be cut is placed flat on the cutting seat, waiting to be smoothed and cut, but the efficiency of smoothing the wrinkled packaging film on the plane is low; at the same time, since the smoothing roller is rotatably connected in the smoothing frame, when the smoothing roller contacts and moves with the packaging film, the smoothing roller is also in a rotating state, and when it contacts the wrinkles on the packaging film, it will roll over them, and cannot completely smooth out the wrinkles on the surface of the packaging film, resulting in poor effect. Summary of the invention

[0005] The embodiment of the present application provides a high-toughness bulk bag production bag cutting machine and a method for using the same, thereby solving the problem in the prior art that the packaging film to be cut is placed flat on the cutting seat, waiting to be smoothed and cut, but the efficiency of smoothing the wrinkled packaging film on the plane is low; at the same time, since the smoothing roller is rotatably connected in the smoothing frame, when the smoothing roller contacts and moves with the packaging film, the smoothing roller is also in a rotating state, and when it contacts the wrinkles on the packaging film, it will roll over them, and cannot completely smooth out the wrinkles on the surface of the packaging film, resulting in poor effect, thereby achieving the goal of tilting the entire device, and the tilted cutting plate can tilt the bulk bag fabric to be cut, and the bulk bag fabric can slide down by its own weight and be laid flat on the cutting plate, thereby improving the smoothing effect on the bulk bag fabric itself; and the cut bulk bag fabric can slide down by its own weight, thereby improving the collection efficiency; at the same time, the roller in contact with the bulk bag fabric can be rotated, thereby improving the effect of unfolding the wrinkles on the bulk bag fabric.

[0053] A method for using a high-toughness container bag production bag cutting machine comprises the following steps:

[0054] S1: When the device needs to cut the bulk bag fabric, the bulk bag fabric roller is fixed by the winding assembly, the bulk bag fabric roller is placed between two clamping plates, and the bulk bag fabric roller is clamped by the extension and contraction of the cylinder;

[0055] S2: Then the second motor starts to work, and the rolled bulk bag fabric is released. The bulk bag fabric falls by its own weight. At the same time, when the bulk bag fabric is light, it can be assisted manually. One end of the bulk bag fabric passes through the protective frame and is placed on the cutting board. After the cutting length is determined, the second motor stops working;

[0056] S3: Before cutting, the electric telescopic rod 2 drives the roller to descend so that the roller contacts the bulk bag fabric. At the same time, the motor 1 drives the rotating rod to rotate so that the two rollers rotate in opposite directions. The wrinkled part needs to be unfolded to straighten the bulk bag fabric.

[0057] S4: After that, the motor stops working; the cutting blade is driven down by the electric telescopic rod to cut the container bag fabric;

[0058] S5: The cut bulk bag fabric can slide down through the slope of the cutting board itself, and at the same time, the motor in the smoothing assembly above the cut bulk bag fabric can drive the roller to rotate quickly, driving the bulk bag fabric to slide down;

[0059] S6: After completing the cutting of a section of the bulk bag fabric, the electric telescopic rod 1 and the electric telescopic rod 2 all rise, and the motor 2 starts working again, and then the bulk bag fabric is released for a section and then stops, and the above steps are repeated. After being smoothed and fixed by the smoothing component, it is cut by the cutting blade, and the work is performed reciprocatingly.

[0060] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0061] First, the device is tilted as a whole. The tilted cutting plate can tilt the bulk bag fabric to be cut, and the bulk bag fabric can slide down by its own weight and lay flat on the cutting plate, thereby improving the smoothing effect of the bulk bag fabric itself; and the cut bulk bag fabric can slide down by its own weight, thereby improving the collection efficiency; at the same time, the roller in contact with the bulk bag fabric can be rotated, thereby improving the unfolding effect of the folds of the bulk bag fabric;

[0062] Secondly, even smoothing. The design of multiple rollers can ensure that in the process of smoothing the bulk bag fabric, the wrinkles on its surface can be smoothed in both the horizontal and vertical directions, and the smoothing effect is more even, reducing the local unevenness that may be caused by a single smoothing roller; improving product quality and stability, reducing the scrap rate, and reducing the generation of wrinkles, which can significantly reduce the scrap rate and improve product quality and stability;

[0063] Thirdly, through the direction of the airflow and the increase of the temperature of the ejected gas, the wrinkled part of the container bag fabric can be restored to its original state more quickly, avoiding the residual wrinkles of the part pressed by the roller cannot be smoothed out, and the continuous ejection of hot air can shape the flat container bag fabric, which can improve the production quality; the ejected gas can also clean the debris dropped during the cutting process and the large amount of dust attached to the container bag fabric; at the same time, when the position is offset, the position of the container bag fabric can be freely adjusted and reset by ejecting air in different directions through the jet ring;

[0064] Fourthly, the outer surface of the drum is changed into an airbag, and the expansion of the airbag on each drum can be controlled individually. When the film is smoothed by jetting, the airbag expands, and the film is quickly unfolded by the extension and retraction of the electric telescopic rod three. At the same time, the airbag is elastic, which can avoid excessive smoothing, pulling the container bag fabric, causing damage, and affecting the quality and appearance of the container bag fabric, thereby improving the quality of the finished product.

[0109] A method for using a high-toughness container bag production bag cutting machine, using the above device, includes the following steps:

[0110] S1: When the device needs to cut the bulk bag fabric, the bulk bag fabric roll is fixed by the winding assembly 300, the bulk bag fabric roll is placed between two clamping plates 350, and the bulk bag fabric roll is clamped by the extension and contraction of the cylinder 340;

When the rollers 280 are driven to rotate by the motor 1 250, the rollers 280 can be controlled to move in the lateral direction by the electric telescopic rod 3 290. During the movement, the wrinkled container bag fabric that is in conflict in the lateral direction is unfolded.

[0128] Uniform smoothing: The design of multiple rollers 280 can ensure that in the process of smoothing the container bag fabric, the wrinkles on its surface can be smoothed in both the horizontal and vertical directions, and the smoothing effect is more uniform, reducing the local unevenness that may be caused by a single smoothing roller; improving product quality and stability, reducing the scrap rate, and reducing the generation of wrinkles, which can significantly reduce the scrap rate and improve product quality and stability.

[0129] Embodiment 3: When the embodiment 2 is in use, the wrinkles on the surface of the bag fabric need to be smoothed by rotating the roller 280 and moving in the lateral direction. However, in the process of use, the roller 280 needs to come into contact with the bag fabric to smooth it out. However, wrinkles will also appear at the contact part between the roller 280 and the bag fabric, making it impossible to smooth it out. Based on this, the solution of the embodiment 2 is improved, such as Figure 9-10 As shown:

[0130] The smoothing component 200 further includes a second groove 283;

[0131] The second groove 283 is annular, and the outer ring of the drum 280 has the second groove 283, and the axis of the second groove 283 is on the same straight line as the axis of the drum 280;

[0132] It also includes a stabilizing assembly 400, the number of which is consistent with the number of rollers 280 and corresponds one to one;

[0133] The stabilizing assembly 400 includes an air jet ring 410, an air pump 420 and an air heater 430;

[0134] The jet ring 410 is annular, the axis of the jet ring 410 is on the same straight line as the axis of the drum 280, the jet ring 410 is fixed in the second groove 283, and the maximum outer diameter of the jet ring 410 is smaller than the maximum outer diameter of the second groove 283;

[0135] When the electric telescopic rod 230 drives the roller 280 to contact the bulk bag fabric to be cut, the jet ring 410 does not contact the bulk bag fabric;

[0136] The jet ring 410 has a plurality of jet ports, and the plurality of jet ports are evenly spaced and distributed in a ring shape;

[0137] The air jet opening on the air jet ring 410 is inclined toward a side away from the fixed plate 270;

[0138] The air pump 1 420 is fixed in the groove 1 281, and the output end of the air pump 1 420 is connected to the jet port on the jet ring 410;

[0139] The air heater 430 is fixed in the groove 281;

[0140] The air heater 430 is a prior art and will not be described in detail here.

[0141] When in use, the air heater 430 works to heat the surrounding air. When the drum 280 descends but does not contact the bulk bag fabric, the air pump 1 420 supplies air to make the jet holes on the jet ring 410 eject hot air. The jet rings 410 on both sides of the fixed plate 270 jet in opposite directions and move away from each other to unfold the wrinkled parts. At the same time, the range of jetting can be adjusted by telescoping the electric telescopic rod 3 290 so that the bulk bag fabric can be completely jetted. After the bulk bag fabric is unfolded, the drum 280 is brought into contact with the bulk bag fabric by the electric telescopic rod 230, and the electric telescopic rod 3 290 drives the drum 280 to move to completely unfold the wrinkles in the horizontal direction of the bulk bag fabric. Then, the motor 1 250 drives the rotating rod 260 to rotate to unfold the wrinkles in the vertical direction of the bulk bag fabric. When the bulk bag fabric deviates during the flattening process, the jet ring 410 is controlled to jet in the same direction as the jet direction of the jet ring 410, and the bulk bag fabric is reset by wind.

[0142] By increasing the direction of the airflow and the temperature of the ejected gas, the wrinkled part of the container bag fabric can be restored to its original state more quickly, avoiding the residual wrinkles pressed by the roller 280 from being unable to be smoothed out, and the continuous ejection of hot air can shape the flat container bag fabric, which can improve the production quality; the ejected gas can also clean the debris dropped during the cutting process and the large amount of dust attached to the container bag fabric; at the same time, when the position is offset, the position of the container bag fabric can be freely adjusted to reset it by ejecting air in different directions through the jet ring 410.

[0143] Embodiment 4: In the above embodiment, when the container bag fabric is smoothed by jetting alone, the effect is poor and the efficiency is low. When the wrinkles are serious and the film is thick, it takes a long time to smooth it. At the same time, when the roller 280 contacts the container bag fabric, the container bag fabric will be pulled, over-smoothed, and damaged. Based on this, the solution of embodiment 3 is improved, such as Fig. 9 , Fig.11 As shown:

[0144] The stabilizing assembly 400 further includes an air bag 440 and an air pump 2 450;

[0145] The airbag 440 is annular, the axis of the airbag 440 is on the same straight line as the axis of the drum 280, the airbag 440 is fixed to the outer ring of the drum 280, the air pump 2 450 is fixed in the groove 1 281, and the output end of the air pump 2 450 is connected to the airbag 440;

[0146] The second groove 283 is located at a side of the airbag 440 away from the fixing plate 270 .

[0147] When the heavier wrinkles in the transverse direction of the container bag fabric are smoothed by the roller 280, the airbag 440 located above the wrinkle position can be controlled to expand and contact the container bag fabric while the multiple jet rings 410 are spraying. At the same time, the length of the electric telescopic rod three 290 above the wrinkle position is extended to gradually unfold the wrinkled part. Then the airbag 440 retracts and does not contact the container bag fabric. The length of the electric telescopic rod three 290 is shortened. Then the airbag 440 expands again to contact the container bag fabric. The length of the electric telescopic rod three 290 is extended again. The work is repeated in this way until the wrinkled part is fully unfolded.

[0148] By changing the outer surface of the roller 280 into an airbag 440, the expansion of the airbag 440 on each roller 280 can be controlled individually. When the film is smoothed by jetting, the airbag 440 expands, and at the same time, the film is quickly unfolded in conjunction with the extension and retraction of the electric telescopic rod 3 290. At the same time, the airbag 440 is elastic, which can avoid excessive smoothing, pulling the container bag fabric, causing damage, and affecting the quality and appearance of the container bag fabric, thereby improving the quality of the finished product.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
