Technical Field

[0001] The invention relates to a cutting and collecting device for food packaging bags, belonging to the technical field of food packaging. Background Art

[0002] Food packaging bags are a type of packaging design. In order to facilitate the preservation and storage of food in life, product packaging bags are produced. Food packaging bags refer to film containers that are in direct contact with food and are used to hold and protect food. They can be divided into ordinary food packaging bags, vacuum food packaging bags, inflated food packaging bags, boiled food packaging bags, steamed food packaging bags and functional food packaging bags. When processing food packaging bags, cutting devices are required to cut them.

[0003] In the prior art, a food packaging bag production line can only cut to a set size during the production process. If cutting to a different size is required, the machine needs to be stopped and then set. When packaging bags of different sizes are required for the same product, the line needs to be divided into two operations. After the line is divided, two groups of people are required to collect and organize the packaging bags, resulting in a huge waste of resources.

[0004] Therefore, the present application proposes a cutting and collecting device for food packaging bags. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the present invention discloses a cutting and collecting device for food packaging bags.

[0006] The technical solution adopted by the present invention is: to provide a cutting and collecting device for food packaging bags, including a base, a conveying device installed on the base for conveying packaging bags, a cutting device installed on the conveying device that can complete the cutting of packaging bags of different sizes on a production line, a driving device for providing power to the cutting device, and a collecting device connected to the driving device; the collecting device can collect packaging bags of different sizes separately.

[0007] Preferably, the conveying device includes a driving wheel, a driven wheel used in conjunction with the driving wheel, a conveying bracket for mounting the driven wheel and the driving wheel, and an axial hole opened on the conveying bracket; a bag seam is provided between the driving wheel and the driven wheel.

[0008] Preferably, the cutting device comprises a cutter, a cutting shaft for mounting the cutter, and a cutting auxiliary wheel mounted on the cutting shaft.

[0009] Preferably, the cutter comprises a cutting main wheel, a slide groove provided on the inner side of the cutting main wheel, a slider arranged between two slide grooves, a threaded hole provided on the slider, and a cutting blade installed on the threaded hole.

[0010] Preferably, the slider is provided with at least one.

[0011] Preferably, the driving device comprises a motor wheel, a motor for mounting the motor wheel, a screw rod arranged on the motor, and a driving gear mounted on the screw rod; the driving device is connected to the cutting auxiliary wheel belt via the motor wheel.

[0012] Preferably, the collecting device includes a driven gear, a driven shaft for mounting the driven gear, a turntable mounted on the driven shaft, and a plurality of collecting barrels arranged under the turntable; the collecting device is meshingly connected with the driving gear through the driven gear; and the collecting barrel is arranged between the turntable and the driven gear.

[0013] Preferably, the diameter of the driven gear is N times that of the driving gear, where N is a constant.

[0014] Preferably, the collecting cylinder is provided with at least one.

[0015] Preferably, the number and distribution positions of the collecting cylinders are determined by the number and positions of the cutting blades and the ratio of the diameters of the driven gear and the driving gear.

[0016] Beneficial effects of the present invention:

[0017] The present invention adopts a cutting device, which can cut the same product on the same production line into packaging bags of different sizes during continuous operation, thereby solving the problem that one production line cannot cut packaging bags of different sizes without stopping the machine. At the same time, a collecting device is adopted to collect packaging bags of different sizes separately, thereby solving the problem that manual sorting is time-consuming and labor-intensive. Specifically, a cutter is provided on the cutting device, and by adding cutting blades to the cutter, the packaging bag can be cut a corresponding number of times by the number of cutting blades when the cutting main wheel rotates one circle. At the same time, the cutting device is linked to the collecting device through a driving device, and each time the cutting device cuts once, the collecting device can rotate one grid. The collecting device is provided with a plurality of collecting barrels, so that the packaging bags cut each time can fall into different collecting barrels, thereby realizing size-based collection.

[0028] The present invention will be further described below in conjunction with specific drawings.

[0029] like Figures 1 to 10 As shown, a cutting and collecting device for food packaging bags is provided, comprising a base 10, a conveying device 20 installed on the base 10 for conveying packaging bags, a cutting device 30 installed on the conveying device 20 and capable of completing the cutting of packaging bags of different sizes on a production line, a driving device 40 for providing power to the cutting device 30, and a collecting device 50 connected to the driving device 40; the collecting device 50 can collect packaging bags of different sizes separately.

[0030] like Figure 1 and Figure 2 As shown, the packaging bag is sent to the cutting device 30 through the conveying device 20. The cutting device 30 is driven by the driving device 40 to cut the conveyed packaging bag. After the cutting is completed, the cut packaging bag falls into the collecting device 50.

[0031] The cutting device 30 can cut packaging bags of different sizes as required and classify them in the collecting device 50 .

[0032] Furthermore, the conveying device 20 includes a driving wheel 21, a driven wheel 22 used in conjunction with the driving wheel 21, a conveying bracket 23 for mounting the driven wheel 22 and the driving wheel 21, and an axial hole 24 opened on the conveying bracket 23; a bag seam is provided between the driving wheel 21 and the driven wheel 22.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the packaging bag passes through the bag gap between the driving wheel 21 and the driven wheel 22 and enters under the cutting device 30.

[0034] The cutting device 30 is mounted on the conveying device 20 through the shaft hole 24 .

[0035] Furthermore, the cutting device 30 includes a cutter 31 , a cutting shaft 32 for mounting the cutter 31 , and a cutting auxiliary wheel 33 mounted on the cutting shaft 32 .

[0036] like Figures 1 to 4 As shown, the cutting device 30 is installed on the conveying device 20 by inserting the cutting shaft 32 into the shaft hole 24, and is connected to the driving device 40 through the cutting auxiliary wheel 33; after the packaging bag passes through the bag seam between the driving wheel 21 and the driven wheel 22, it is cut by the cutter 31 when it is conveyed to a certain length, and the length is determined according to actual needs.

[0037] Furthermore, the cutter 31 includes a cutting main wheel 311 , a slide groove 312 provided inside the cutting main wheel 311 , a slider 313 arranged between the two slide grooves 312 , a threaded hole 314 provided on the slider 313 , and a cutting blade 315 installed on the threaded hole 314 .

[0038] Furthermore, the slider 313 is provided with at least one.

[0039] like Figures 1 to 7 As shown, after the packaging bag passes through the bag-passing seam between the driving wheel 21 and the driven wheel 22 , it is cut by the cutting blade 315 on the cutter 31 when it is transported to a certain length.

[0040] The cutting blade 315 is connected to the slider 313 by rotating one end into the threaded hole 314 . When rotating to the bottom, the bottom end abuts against the cutting main wheel 311 , thereby fixing the cutting blade 315 on the cutting main wheel 311 .

[0041] If it is necessary to cut out packaging bags of different sizes, it is only necessary to add a cutting blade 315 to the cutting main wheel 311; Figure 7 For example, when the number of cutting blades 315 of the cutting main wheel 311 is 2, and Figure 7 The angle is set, and when the cutting main wheel 311 rotates one circle, the length ratio of the two packaging bags cut out is 1:2.

[0042] Furthermore, the driving device 40 includes a motor wheel 41, a motor 42 for mounting the motor wheel 41, a screw rod 43 disposed on the motor 42, and a driving gear 44 mounted on the screw rod 43; the driving device 40 is connected to the cutting auxiliary wheel 33 by a belt through the motor wheel 41.

[0043] like Figure 8 As shown, the driving gear 44 is rotatably connected to the screw rod 43 and can be easily moved.

[0044] Furthermore, the collecting device 50 includes a driven gear 51, a driven shaft 52 for mounting the driven gear 51, a turntable 53 mounted on the driven shaft 52, and a plurality of collecting barrels 54 arranged under the turntable 53; the collecting device 50 is meshingly connected with the driving gear 44 through the driven gear 51; the collecting barrel 54 is arranged between the turntable 53 and the driven gear 51.

[0045] Furthermore, the diameter of the driven gear 51 is N times that of the driving gear 44 , where N is a constant.

[0046] Furthermore, the collecting tube 54 is provided with at least one.

[0047] Furthermore, the number and distribution positions of the collecting barrels 54 are determined by the number and position of the cutting blades 315 and the diameter ratio of the driven gear 51 and the driving gear 44 .

[0048] like Figures 1 to 10 As shown, the diameter of the motor wheel 41 on the driving device 40 is the same as the cutting auxiliary wheel 33, which can ensure that the rotation rate of the motor 42 is consistent with the rotation rate of the cutting main wheel 311. When the diameter of the driven gear 51 on the collecting device 50 is N times that of the driving gear 44 on the driving device 40, the rotation rate of the cutting main wheel 311 is N times the rotation rate of the collecting device 50.

[0049] Taking the above situation as an example, when there is only one cutting blade 315 on the cutting main wheel 311, the diameter of the driven gear 51 can be set to 1 times of the driving gear 44 according to the actual situation, and the collecting cylinder 54 on the collecting device 50 is set to a large cylinder, or a small cylinder at the edge position. If the diameter of the driven gear 51 is adjusted to 6 times of the driving gear 44, the collecting cylinder 54 on the collecting device 50 is set to 6 small cylinders evenly distributed along the center of the circle (such as Figure 1 shown).

[0050] The above is a case where a cutting blade 315 is used to cut out a packaging bag of size. Now the cutting blade 315 is adjusted to the following size: Figure 7 The situation shown.

[0051] At this time, it can be seen that the cutting main wheel 311 rotates in two sections, one of which has an arc length twice that of the other section. The diameter ratio of the driven gear 51 and the driving gear 44 can be set first, and the ratio should be 2N times. In this embodiment, the diameter of the driven gear 51 is twice that of the driving gear 44. According to the arc length 2:1 principle, the collecting tube 54 is designed as follows: Fig.10As shown in the figure, the packaging bags are separated and fall into the collection tube 54 according to the size of long→short→long→short→long (starting point).

[0052] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
