[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example

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

[0028] like Figure 1 and Figure 2 As shown, the conveying drive assembly 100 includes: a conveying drive unit 110 , a conveying drive bracket 120 , an active synchronous wheel 130 , a conveying drive belt 140 and two tension wheels 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 conveying belt 250 and a front end pressing plate 260.

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

[0031] like Figure 1 and Figure 2As shown, in this embodiment, the conveying drive unit 110 is a servo motor, which is fixed on the conveying drive bracket 120; the conveying drive belt 140 is sleeved on the active synchronous wheel 130, the two ends of the front active roller 210 of the front conveying component 200, and the two ends of the rear active roller 310 of the rear conveying component 300, and meshes with the three for transmission. The output shaft of the conveying drive unit 110 is fixedly connected to the active synchronous wheel 130, driving the active synchronous wheel 130 to rotate, driving the front active roller 210 and the rear active roller 310 to rotate synchronously. Of course, the front conveying component 200 and the rear conveying component 300 can use different drive sources, as long as the conveying speed is synchronized. In this embodiment, the front conveying component 200 and the rear conveying component 300 use the same drive source, which can ensure that the conveying speeds of the two are completely synchronized, and there is no need to control their conveying speeds separately.

[0032] like Figure 3 As shown, the front conveying belt 250 in the front conveying assembly 200 is sleeved on the middle part of the front driving roller 210 and the front driven roller 240. The front negative pressure chamber 220 is located below the conveying surface of the front conveying belt 250, and the front suction port 230 is located on one side of the front negative pressure chamber 220 to provide negative pressure. The front conveying belt 250 has a plurality of suction holes, which can adsorb the conveyed materials on the front conveying belt 250. There are front pressure plates 260 on both sides of the front conveying belt 250 of the front conveying assembly 200, which can press both sides of the materials. The feeding position of the front pressure plate 260 has a guide port to facilitate the entry of materials.

[0033] like Figure 4 As shown, the rear-end conveying belt 350 in the rear-end conveying assembly 300 is sleeved on the middle part of the rear-end active 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 conveying belt 350, and the rear-end suction port 330 is located on one side of the rear-end negative pressure chamber 320 to provide negative pressure. The rear-end conveying belt 350 is provided with a plurality of suction holes, which can adsorb the conveyed materials on the rear-end conveying belt 350. There are rear-end pressing plates 360 on both sides of the rear-end conveying belt 350 of the rear-end conveying assembly 300, which can press both sides of the materials. The feeding position of the rear-end pressing plate 370 has a guide port to facilitate the entry of materials. The rear-end pressing plate 370 is arranged at the end of the conveying of the rear-end conveying 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 driving 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 roller driving unit 420 is a roller driving cylinder, the fixed end of which is fixed to the roller support 410, and the roller rotating seat 430 is fixed to the telescopic end of the roller driving unit 420. The upper roller 440 is rotatably connected to the roller rotating seat 430.

[0036] Preferably, two compression springs 460 are symmetrically arranged on both sides of the pressure roller driving unit 420. One end of the compression spring 460 is sleeved on the bolt fixed on the pressure roller bracket 410, and the length of the bolt is shorter than the length of the compression spring 460 after compression; 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 external air source of the pressure roller driving unit 420 from being suddenly interrupted or the equipment is powered off, and re-debugging is required when resuming production. At this time, if there is no compression spring 460 to press the upper pressure roller 440, the weight of the upper pressure roller 440 itself cannot press the roll film, and the roll film will flow back. When resuming production, it is necessary to operate the roll film and perform secondary debugging of the machine.

[0037] Preferably, the circumference of the upper pressing roller 440 is provided with a plurality of pressing roller grooves 441. One end of the guide member 450 is fixed to the pressing roller bracket 410, and the other end is provided with a plurality of "J"-shaped guide strips 451. The arc shape of the "J"-shaped guide strip 451 matches the pressing roller groove 441, is embedded in the pressing roller groove 441, and is located at the input side of the upper pressing roller 440; the straight line of the "J"-shaped guide strip 451 extends forward from the circumference of the upper pressing roller 440. This arrangement is to prevent the roll film from being attached to the upper pressing roller 440 when it is transported through the upper pressing roller 440.

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

[0039] In order to prevent the upper pressure roller 440 from being insufficient in conveying efficiency and to prevent the front conveying belt 250 from being pressed down, the front conveying assembly 200 further includes a lower pressure roller, which is located below the upper pressure roller 440. When the pressure roller driving unit 420 drives the upper pressure roller 440 to press on the front conveying belt 250, the upper pressure roller 440 and the lower pressure roller are respectively located on both sides of the front conveying belt 250, and simultaneously press the front conveying belt 250 to convey materials.

[0040] In order to simplify the components and take into account the synchronization of the conveying speed, in this embodiment, the front driving roller and the lower pressure roller share a conveying roller, that is, the front driving roller 210 is both the driving roller of the front conveying assembly 200 and the lower pressure roller matched with the upper pressure roller 440. Of course, if the front driving roller 210 and the front driven roller 240 of the front conveying assembly 200 are interchanged, the front driven roller 240 can also be used as the lower pressure roller; or the front conveying assembly 200 can also be provided with a lower pressure roller between the front driving roller 210 and the front driven roller 240.

[0041] In this embodiment, the pressure roller driving part 420 extends out to drive 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 respectively located on both sides of the front conveying belt 250, and simultaneously apply pressure to the front conveying belt 250 to convey materials.

[0042] like Figure 7 As shown, the cutter assembly 500 is disposed between the front conveying assembly 200 and the rear conveying assembly 300 to cut the material. The cutter assembly 500 includes: a cutter support 510, an upper cutter driving 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 driving part 520 is an upper cutter driving cylinder, and the fixed end of the upper cutter driving cylinder is fixed to the cutter bracket 510; the upper cutter fixing plate 540 is fixed to the telescopic end of the upper cutter driving part 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 bar 451 can be attached to the front end support plate 570. The upper cutter driving part 520 extends to drive the upper cutter 550 to move downward and cooperate with the lower cutter 560 to cut the material.

[0044] In order to ensure the stability of the upper cutter moving downward, two guide rails 530 are fixed on the cutter bracket 510, and the two slide rails are symmetrically fixed on both sides of the upper cutter driving part 520. There are two sliders on the upper cutter fixing plate 540. The sliders of the upper cutter fixing plate 540 match the guide rails 530, and the two can slide relative to each other.

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

[0046] The bag pressing adjustment plate 610 has a long circular hole, which is fixed to the cutter bracket 510 of the cutter assembly 500 by fasteners to achieve 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, and the fixed end of the bag pressing drive unit 630 is fixed to the bag pressing drive fixing plate 620; the pressing 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 the material needs to be cut, the bag pressing drive unit 630 drives the pressing plate 640 to press on the rear end material pressing plate 360 ​​of the rear end conveying assembly 300; to prevent the upper edge of the bag from tilting upward at the cut-off point of the bag, which is not conducive to hanging the bag.

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

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

[0049] Roll film feeding mode:

[0050] Before the film roll is produced, manual adjustment is required to pass the film roll through the film roll guide roller 700, which plays the role of guiding the film roll track. The film roll then passes between the upper pressure roller 440 of the pressure roller assembly 400 and the front conveyor belt 250; then passes between the upper cutting knife 550 and the lower cutting knife 560; and finally passes through the pressing plate 640 and the rear pressing plate 360.

[0051] The pressure roller driving unit 420 drives the upper pressure roller 440 to press downward, pressing the roll film bag onto the front conveying belt 250. At this time, the front active roller 210, that is, the lower pressure roller and the upper pressure roller 440, are pressed together on both sides of the front conveying belt 250. Fig. 9 After manual debugging is completed, the conveying drive unit 110 of the conveying drive assembly 100 is started to drive both ends of the front active roller 210 and both ends of the rear active roller 310 to rotate synchronously to ensure that the conveying speed is constant.

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

[0053] After the cutting is completed, the upper cutter 550 of the cutter assembly 500 and the pressing 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 are synchronously conveyed again. The rear conveying assembly 300 conveys the cut roll film bag to the next process; the front conveying assembly 200 and the pressing roller assembly 400 convey the subsequent roll film bag to the next cutting position.

[0054] Pre-made bag feeding mode:

[0055] The pressure roller driving part 420 of the pressure roller assembly 400 retracts, and the upper pressure roller 440 moves upward and leaves the front conveying belt 250 .

[0056] At this time, the negative pressure suction of the front conveying assembly 200 and the rear conveying assembly 300 firmly adsorbs the prefabricated bag on the conveyor belt, and the upper pressing roller 440 does not participate in the conveying. Fig.10 shown.

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

[0058] After the cutting is completed, the upper cutter 550 of the cutter assembly 500 and the pressing 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 are synchronously conveyed again. The rear conveying assembly 300 conveys the cut roll film bag to the next process such as the bag hanging area. The front conveying assembly 200 and the pressing roller assembly 400 convey the subsequent prefabricated bag to the next cutting position.

[0059] Of course, if the pre-made bag does not need to be cut, the pre-made bag is directly transported to the next process through the front conveying assembly 200 and the rear conveying assembly 300, and the cutter assembly 500 does not perform cutting.

[0060] The embodiments described above are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
