In the field of packaging, the film material feeding device pulls the rolled packaging film to the laminating station. For example, the Chinese patent with the announcement number CN220844783U discloses a packaging film feeding device with a guide mechanism, whose working principle is to place the packaging film between two winding rollers, start motor one, and drive the winding roller to rotate, so that the two winding rollers convey the packaging film, and convey the packaging film to the outside of the arc plate, start motor two, and drive the turntable to rotate through the output end of motor two, and drive the packaging film on the outer wall of the arc plate to be conveyed through the rotation of the slide. The above-mentioned packaging film feeding device has the following problems: when the packaging film is about to be loaded, the front end of the new packaging film needs to be placed between the winding rollers, causing the feeding device to pause, thereby affecting the packaging film loading speed, and then reducing the subsequent packaging efficiency. In view of this, the utility model proposes a non-stop film material feeding device to solve the above-mentioned problems. Utility Model Content

[0021] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0022] Reference Figure 1-2 , an embodiment of a non-stop film material feeding device of the utility model is proposed:

[0023] A non-stop film material feeding device includes a traction mechanism 1 for conveying film material forward, a welding mechanism 2, a moving mechanism 3, and a storage mechanism in sequence along the front-to-back direction. The storage mechanism includes at least two parallel material shafts 41, each of which stores film material rolls. The film material of one of the film material rolls stored in the storage mechanism passes through the welding mechanism 2 and the traction mechanism 1 in sequence. A detection mechanism 5 is provided between the welding mechanism 2 and the storage mechanism. When the detection mechanism 5 detects that the film material roll conveyed by the traction mechanism 1 is about to be loaded, the moving mechanism 3 grabs the front end of the other film material roll of the storage mechanism to the welding mechanism 2, and the welding mechanism 2 welds the ends of the two film material rolls to avoid the problem of suspension of loading due to exhaustion of the film material roll, thereby realizing non-stop loading.

[0024] The material storage mechanism also includes a support plate with the same number as the material shaft 41, and two first guide shafts 42 are symmetrically arranged in the up-down direction at the rear of the support plate. The front end of the film roll on the material shaft 41 passes through the gap between the two first guide shafts 42 and is then placed on the support plate. The first guide shaft 42 is used to position the film material so that the front end of the film roll is stably placed on the support plate. The first guide shaft 42 can also be used to pull the film material so that the film material is more stably loaded.

[0025] The moving mechanism 3 includes a negative pressure suction plate for sucking the front end of the film roll, and a moving component for driving the negative pressure suction plate to move between the welding mechanism 2 and the support plate. The utility model sucks the film material through the negative pressure suction plate, keeps the film material flat during the sucking process, and the moving component translates the film material in the front-to-back direction or vertical direction, so as to avoid the film roll from deviating in its width direction as much as possible, so as to facilitate the subsequent welding mechanism 2 to weld the film roll.

[0026] The welding mechanism 2 includes a welding support plate 21 , a heating component 22 located below the welding support plate 21 , and a moving component 23 .

[0027] In this embodiment, the film material feeding device is provided with two material shafts 41 and two support plates, which further reduces the number of components of the feeding device, thereby reducing the cost.

[0028] The two support plates are respectively a first support plate 43 and a second support plate 44 . The first support plate 43 and the welding support plate 21 are located at the same height, and the second support plate 44 is located at a higher height than the welding support plate 21 .

[0029] The moving mechanism 3 includes a first negative pressure suction plate 31 located between the first support plate 43 and the second support plate 44, and a second negative pressure suction plate 32 located above the second support plate 44. The moving assembly includes a first translation device 33 for moving the first negative pressure suction plate 31 in the front-to-back direction, a lifting device 34 for the second negative pressure suction plate 32, and a second translation device 35 for moving the lifting device 34 in the front-to-back direction. Since the first support plate 43 and the welding support plate 21 are located at the same height, the first translation device 33 does not need the lifting device 34, thereby reducing the number of components of the moving assembly. Moreover, the position of the second support plate 44 is higher than the position of the welding support plate 21, and the position of the lifting device 34 and the first translation device 33 are staggered.

[0030] Specifically, in the horizontal direction, the first support plate 43 is closer to the welding support plate 21 than the second support plate 44 . The detection mechanism 5 is arranged above the first support plate 43 , and the detection mechanism 5 can detect whether there is film material on the first support plate 43 and above the detection mechanism 5 .

[0031] Specifically, the material shaft 41 is an inflatable shaft, and the inflatable shaft fixes the film material roll by inflation.

[0032] The traction mechanism 1 includes two second guide shafts 11 symmetrically arranged in the vertical direction, a traction shaft 12 located in front of the second guide shaft 11, and limiting plates are arranged at both ends of the traction shaft 12, and the distance between the two limiting plates is consistent with the width of the film material. The two second guide shafts 11 are used to convey the film material to the traction shafts 12, and the film material contacts the surface of the traction shafts 12. The limiting plates are used to limit the position of the film material to further prevent the film material from deviating along its width direction.

[0033] The film material feeding device also includes a vertical flat plate 6 , and the first guide shaft 42 , the support plate, the moving mechanism 3 , the second guide shaft 11 , and the traction shaft 12 are all mounted on the vertical flat plate 6 .

[0034] The first translation device 33 includes a first guide rail installed on the vertical plate 6, a first slider matched with the first guide rail, and a first power component for driving the first slider to slide on the first guide rail, and the first slider is fixedly connected to the first negative pressure suction plate 31. The lifting device 34 includes an upright lifting plate, an upright second guide rail provided on the lifting plate, a second slider matched with the second guide rail, and a second power component for driving the second slider to slide on the second guide rail, and the second slider is fixedly connected to the second negative pressure suction plate 32. The second translation device 35 includes a third guide rail installed on the vertical plate 6, a third slider matched with the third guide rail, and a third power component for driving the third slider to slide on the third guide rail, and the third slider is fixedly connected to the lifting plate.

[0035] The feeding process of the utility model is as follows: Figure 2 As shown, two material shafts 41 store film rolls, and the front end of one of the film rolls passes through the gap between the two first guide shafts 42, the top of the first support plate 43, the welding support plate 21, the gap between the two second guide shafts 11, and the traction shaft 12 in sequence, and the second guide shaft 11 pulls the film material forward. The front end of the other film roll passes through the gap between the two first guide shafts 42 and is placed on the second support plate 44. When the detection mechanism 5 detects that there is no film material above the first support plate 43, the second negative pressure suction plate 32 sucks the front end of the roll on the second support plate 44, and then the moving mechanism 3 moves the second negative pressure suction plate 32 and the film material to the welding support plate 21, and the heating component 22 approaches the welding support plate 21 in advance to preheat the welding support plate 21, and the head and tail of the two film rolls are welded on the welding support plate 21. When the film material is welded, the moving component 23 drives the moving heating component 22 away from the welding support plate 21. Finally, the air shaft is deflated, and the operator removes the used film roll and replaces it with a new film roll.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
