[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] In this embodiment, as Figure 1 As shown, the novel dual-purpose feeding device includes: a conveyor drive assembly 100, a front conveyor assembly 200, a rear conveyor assembly 300, a pressure roller assembly 400, a cutter assembly 500, a bag pressing assembly 600, and a film roll guide roller 700.

[0028] like Figure 1 and Figure 2 As shown, the conveyor drive assembly 100 includes: a conveyor drive unit 110, a conveyor drive bracket 120, an active synchronizing pulley 130, a conveyor drive belt 140, and two tensioning pulleys 150.

[0029] like Figure 3 As shown, the front-end conveying assembly 200 is a negative pressure suction conveying assembly, including: a front-end active roller 210, a front-end negative pressure chamber 220, a front-end suction port 230, a front-end driven roller 240, a front-end conveyor belt 250, and a front-end pressure plate 260.

[0030] like Figure 4 As shown, the rear conveying assembly 300 is a negative pressure suction conveying assembly, including a rear active roller 310, a rear negative pressure chamber 320, a rear suction port 330, a rear driven roller 340, a rear conveyor belt 350, a rear conveying platform 360, and a rear pressing plate 370.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, the conveying drive unit 110 is a servo motor, fixed on the conveying drive bracket 120; the conveying drive belt 140 is fitted onto the active synchronous pulley 130, both ends of the front active roller 210 of the front conveying assembly 200, and both ends of the rear active roller 310 of the rear conveying assembly 300, engaging with these three components for transmission. The output shaft of the conveying drive unit 110 is fixedly connected to the active synchronous pulley 130, driving the active synchronous pulley 130 to rotate, thereby causing the front active roller 210 and the rear active roller 310 to rotate synchronously. Of course, the front conveying assembly 200 and the rear conveying assembly 300 can use different drive sources, as long as the conveying speeds are synchronized. In this embodiment, the front conveying assembly 200 and the rear conveying assembly 300 use the same drive source, which ensures that their conveying speeds are completely synchronized, eliminating the need to control their conveying speeds separately.

[0032] like Figure 3 As shown, in the front-end conveyor assembly 200, the front-end conveyor belt 250 is fitted onto the middle of the front-end drive roller 210 and the front-end driven roller 240. The front-end negative pressure chamber 220 is located below the conveying surface of the front-end conveyor belt 250, and the front-end suction port 230 is located on one side of the front-end negative pressure chamber 220, providing negative pressure. The front-end conveyor belt 250 has several suction holes, which can adsorb the conveyed material onto the front-end conveyor belt 250. The front-end conveyor belt 250 of the front-end conveyor assembly 200 has front-end pressure plates 260 on both sides, which can press down the sides of the material. The feed position of the front-end pressure plate 260 has a guide port to facilitate material entry.

[0033] like Figure 4 As shown, in the rear-end conveyor assembly 300, the rear-end conveyor belt 350 is fitted onto the middle of the rear-end drive roller 310 and the rear-end driven roller 340. The rear-end negative pressure chamber 320 is located below the conveying surface of the rear-end conveyor belt 350, and the rear-end suction port 330 is located on one side of the rear-end negative pressure chamber 320, providing negative pressure. The rear-end conveyor belt 350 has several suction holes, which can adsorb the conveyed material onto the rear-end conveyor belt 350. The rear-end conveyor belt 350 of the rear-end conveyor assembly 300 has rear-end pressure plates 360 on both sides, which can press down the material on both sides. The feed position of the rear-end pressure plate 370 has a guide port to facilitate material entry. The rear-end pressure plate 370 is located at the end of the rear-end conveyor belt 350.

[0034] like Figure 5 and Figure 6 As shown, the pressure roller assembly 400 includes: a pressure roller bracket 410, a pressure roller drive unit 420, a pressure roller rotating seat 430, an upper pressure roller 440, a guide member 450, and two compression springs 460.

[0035] In this embodiment, the pressure roller drive unit 420 is a pressure roller drive cylinder. The fixed end of the pressure roller drive cylinder is fixed on the pressure roller bracket 410, and the pressure roller rotating seat 430 is fixed on the telescopic end of the pressure roller drive unit 420. The upper pressure roller 440 and the pressure roller rotating seat 430 are rotatably connected.

[0036] Preferably, two compression springs 460 are symmetrically arranged on both sides of the pressure roller drive unit 420. One end of the compression spring 460 is fitted onto a bolt fixed to the pressure roller bracket 410, and the bolt length is shorter than the compressed length of the compression spring 460; the other end of the compression spring 460 is embedded in the corresponding hole of the pressure roller rotating seat 430. The two compression springs 460 are to prevent the need for readjustment when production resumes after a sudden interruption of the external air supply to the pressure roller drive unit 420 or a power outage. If the compression spring 460 is not pressing down on the upper pressure roller 440, the weight of the upper pressure roller 440 itself will not be able to hold the film roll down, and the film roll will flow back. When production resumes, the film roll needs to be operated and the machine needs to be readjusted again.

[0037] Preferably, the upper pressure roller 440 has several pressure roller grooves 441 on its circumference. One end of the guide member 450 is fixed to the pressure roller bracket 410, and the other end has several "J"-shaped guide strips 451. The arc shape of the "J"-shaped guide strips 451 matches the pressure roller grooves 441, is embedded in the pressure roller grooves 441, and is located on the input side of the upper pressure roller 440; the straight lines of the "J"-shaped guide strips 451 extend forward from the circumference of the upper pressure roller 440. This arrangement is to prevent the film roll from sticking to the upper pressure roller 440 when it passes through the upper pressure roller 440 for conveying.

[0038] The pressure roller drive unit 420 can drive the upper pressure roller 440 to press onto the front conveyor belt 250, pressing the material on the upper pressure roller 440 onto the front conveyor assembly 200 for conveying.

[0039] To prevent insufficient conveying efficiency from the upper pressure roller 440 alone, and to prevent the front conveyor belt 250 from sinking under pressure, the front conveyor assembly 200 also includes a lower pressure roller, which is located below the upper pressure roller 440. When the pressure roller drive unit 420 drives the upper pressure roller 440 to press against the front conveyor belt 250, the upper pressure roller 440 and the lower pressure roller are located on both sides of the front conveyor belt 250, respectively, and simultaneously apply pressure to the front conveyor belt 250 to convey materials.

[0040] To simplify the components and ensure synchronized conveying speed, in this embodiment, the front drive roller and the lower pressure roller share a single conveying roller. That is, the front drive roller 210 is both the drive roller of the front conveying assembly 200 and the lower pressure roller that matches the upper pressure roller 440. Of course, if the positions of the front drive roller 210 and the front driven roller 240 of the front conveying assembly 200 are interchanged, the front driven roller 240 can also serve as the lower pressure roller; alternatively, the front conveying assembly 200 can also have a separate lower pressure roller between the front drive roller 210 and the front driven roller 240.

[0041] In this embodiment, the pressure roller drive unit 420 extends and drives the upper pressure roller 440 to move downward. The upper pressure roller 440 and the front active roller 210, i.e. the lower pressure roller, are located on both sides of the front conveyor belt 250, and simultaneously apply pressure to the front conveyor belt 250 to convey materials.

[0042] like Figure 7 As shown, the cutter assembly 500 is disposed between the front conveyor assembly 200 and the rear conveyor assembly 300, and can cut materials. The cutter assembly 500 includes: a cutter bracket 510, an upper cutter drive unit 520, an upper cutter fixing plate 540, an upper cutter 550, a lower cutter 560, a front support plate 570, and a rear support plate 580.

[0043] In this embodiment, the upper cutter drive unit 520 is an upper cutter drive cylinder, and the fixed end of the upper cutter drive cylinder is fixed to the cutter bracket 510; the upper cutter fixing plate 540 is fixed to the telescopic end of the upper cutter drive unit 520. The upper cutter 550 is fixed to the upper cutter fixing plate 540. The lower cutter 560 is fixed to the cutter bracket 510 and is located below the upper cutter 550. The front end support plate 570 and the rear end support plate 580 are fixed to the cutter bracket 510 and are located on both sides of the lower cutter 560. The front end of the straight position of the "J"-shaped guide strip 451 can be attached to the front end support plate 570. The upper cutter drive unit 520 extends, driving the upper cutter 550 to move downward, cooperating with the lower cutter 560 to cut the material.

[0044] To ensure smooth downward movement of the upper cutter, two guide rails 530 are fixed to the cutter bracket 510, and the two guide rails are symmetrically fixed on both sides of the upper cutter drive unit 520. The upper cutter fixing plate 540 has two sliders. The sliders of the upper cutter fixing plate 540 are matched with the guide rails 530, and the two can slide relative to each other.

[0045] like Figure 8 As shown, in this embodiment, the bag pressing assembly 600 includes: a bag pressing adjustment plate 610, a bag pressing drive fixing plate 620, a bag pressing drive part 630, and a pressing plate 640.

[0046] The bag-pressing adjustment plate 610 has an elongated hole and is fixed to the cutter bracket 510 of the cutter assembly 500 by fasteners, achieving an adjustable connection between the two. The bag-pressing drive fixing plate 620 is fixed to the bag-pressing adjustment plate 610. The bag-pressing drive unit 630 is a bag-pressing drive cylinder, with its fixed end fixed to the bag-pressing drive fixing plate 620; the pressure plate 640 is fixed to the telescopic end of the bag-pressing drive unit 630. The bag-pressing drive unit 630 cooperates with the upper cutter drive unit 520. When cutting materials, the bag-pressing drive unit 630 drives the pressure plate 640 to press against the rear pressure plate 360 ​​of the rear conveying assembly 300; this prevents the upper edge of the bag from tilting upwards at the cut point, which would be detrimental to bag hanging.

[0047] In this embodiment, the conveying surfaces of the front conveyor belt 250, the front support plate 570, the rear support plate 580, the rear conveyor belt 350, and the rear pressure plate 370 are on the same plane. The film guide roller 700 is located in front of the upper pressure roller 440 in the conveying direction and guides the material and the film roll.

[0048] Working process of the new dual-purpose feeding device:

[0049] Roll film feeding mode:

[0050] Before the film roll is fed into production, manual adjustment is required to guide the film roll through the film roll guide roller 700, which serves to correct the film roll trajectory. The film roll then passes between the upper pressure roller 440 of the pressure roller assembly 400 and the front conveyor belt 250; then between the upper cutter 550 and the lower cutter 560; and finally passes through the pressure plate 640 and the rear pressure plate 360.

[0051] The pressure roller drive unit 420 drives the upper pressure roller 440 downward to press the roll film bag onto the front conveyor belt 250. At this time, the front drive roller 210, which is the lower pressure roller, and the upper pressure roller 440 together press on both sides of the front conveyor belt 250. Figure 9 As shown. After manual debugging, start the conveying drive unit 110 of the conveying drive assembly 100 to drive the two ends of the front active roller 210 and the two ends of the rear active roller 310 to rotate synchronously, ensuring that the conveying speed is constant.

[0052] The front-end conveying assembly 200 drives the roll of film, conveying the roll of film pressed in the middle to the cutting assembly 500. When the roll of film reaches the cutting position, the conveying drive unit 110 stops rotating, the front-end conveying assembly 200 and the rear-end conveying assembly 300 stop conveying, and the pressure plate 640 of the bag pressing assembly 600 moves downward to press the roll of film. The upper cutting drive unit 520 of the cutting assembly 500 drives the upper cutting blade 550 to move downward, cooperating with the lower cutting blade 560 to cut the roll of film.

[0053] After cutting is completed, the upper cutter 550 of the cutter assembly 500 and the pressure plate 640 of the bag pressing assembly 600 are reset. Then the conveying drive unit 110 is restarted, and the front conveying assembly 200 and the rear conveying assembly 300 convey synchronously. The rear conveying assembly 300 conveys the cut roll film bag to the next process; the front conveying assembly 200 and the pressure roller assembly 400 convey the subsequent roll film bags to the next cutting position.

[0054] Pre-made bag feeding mode:

[0055] The pressure roller drive section 420 of the pressure roller assembly 400 retracts, and the upper pressure roller 440 moves upward and away from the front conveyor belt 250.

[0056] At this time, the negative pressure suction of the front conveyor component 200 and the rear conveyor component 300 firmly adsorbs the pre-made bag onto the conveyor belt, and the upper pressure roller 440 does not participate in the conveying. Figure 10 As shown.

[0057] When the pre-made bag reaches the cutting position, the conveyor drive unit 110 stops rotating, the front conveyor assembly 200 and the rear conveyor assembly 300 stop conveying, and the pressure plate 640 of the bag pressing assembly 600 moves downward to press the pre-made bag down. The upper cutter drive unit 520 of the cutter assembly 500 drives the upper cutter 550 to move downward, cooperating with the lower cutter 560 to cut the pre-made bag.

[0058] After cutting is completed, the upper cutter 550 of the cutter assembly 500 and the pressure plate 640 of the bag pressing assembly 600 are reset. Then, the conveyor drive unit 110 restarts, and the front conveyor assembly 200 and the rear conveyor assembly 300 simultaneously convey the bags. The rear conveyor assembly 300 transports the cut roll film bags to the next process, such as the bag hanging area. The front conveyor assembly 200 and the pressure roller assembly 400 transport the subsequent pre-made bags to the next cutting position.

[0059] Of course, if the prefabricated bag does not need to be cut, the prefabricated bag is directly conveyed to the next process through the front conveyor component 200 and the rear conveyor component 300, and the cutting component 500 does not cut it.

[0060] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
