[0002] Packaging bags are commonly used packaging materials in the food industry. Packaging bags are usually made of heat-sealed packaging bag films, and the heat-sealed packaging bag films have a point-interrupted strip structure.

[0003] At present, the point-break packaging bag film needs to be rolled up after production. Most of the existing rolling methods utilize a driving mechanism to drive the roll to rotate, and the point-break packaging bag film is rolled up on the outside of the roll when the roll rotates. When the point-break packaging bag film on the outside of the roll is rolled up to a predetermined number of turns, it is necessary to manually remove the current roll from the rolling station, and then place a new roll at the rolling station to continue rolling up the subsequent point-break packaging bag film. This rolling method is relatively traditional, and it takes a lot of time to manually replace the roll, so that the subsequent point-break packaging bag film cannot be rolled up in time, resulting in a relatively low rolling efficiency of the point-break packaging bag film.

DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] See also Figure 1 as well as Figure 2 The present embodiment provides a packaging bag film roll winding device, including a support platform 10, a turntable 20, a winding assembly 30, a driving assembly 40 and a clamping assembly 50. Two groups of bracket plates 102 are fixedly arranged on the upper part of the support platform 10. The two groups of bracket plates 102 are relatively distributed. The turntable 20 is rotatably mounted on one group of the bracket plates 102, and the driving assembly 40 is mounted on the other group of the bracket plates 102. The winding assembly 30 is provided with a plurality of groups, and a plurality of the winding assemblies 30 are rotatably arranged at an eccentric position on one side of the turntable 20. The winding components 30 are distributed in a ring-shaped interval at an eccentric position on one side of the turntable 20. When the driving component 40 runs in the forward direction, it can drive the turntable 20 to rotate, and then several of the winding components 30 perform circular motion. When the driving component 40 runs in the reverse direction, it can drive the winding components 30 to rotate to wind up the point-break type packaging bag film. The clamping component 50 is arranged on one side of the turntable 20. After the point-break type packaging bag film is wound around a predetermined number of turns on the outside of a group of the winding components 30, the clamping component 50 is used to clamp the subsequent point-break type packaging bag film.

[0036] Initially, a certain group of winding components 30 is at the winding station. When the point-break type packaging bag film needs to be wound up, the driving component 40 runs in the reverse direction to drive the plurality of winding components 30 to rotate relative to the turntable 20. The winding components 30 at the winding station wind the point-break type packaging bag film on the outside thereof. After the point-break type packaging bag film on the outside of the group of winding components 30 is wound a predetermined number of times, the clamping component 50 clamps the subsequent point-break type packaging bag film. At this time, relying on the rotational power of the group of winding components 30, the point-break type packaging bag film on the outside of the group of winding components 30 and the subsequent point-break type packaging bag film are connected. Disconnect, then the driving component 40 moves forward, thereby driving the turntable 20 to rotate a predetermined angle. When the turntable 20 rotates a predetermined angle, it can drive several winding components 30 to move in a circle at a predetermined angle, so that the winding component 30 wound with the discontinuous packaging bag film is turned away from the current winding station, and at the same time, the next group of winding components 30 is rotated to the winding station, and then the driving component 40 runs in the opposite direction again to drive the next group of winding components 30 to rotate compared with the turntable 20, and then the subsequent discontinuous packaging bag film is wound, and such a reciprocating cycle can realize the continuous automatic winding of the discontinuous packaging bag film.

[0037] See also Figure 1 , Figure 3 as well as Figure 5 In one embodiment, the winding assembly 30 includes a reel 301, one end of the reel 301 is rotatably connected to the turntable 20, a gear 303 is fixedly provided at one end of the outside of the reel 301, the driving assembly 40 includes a toothed disc 401, a rotating shaft 402 and a motor 403, the motor 403 is fixedly provided on the side wall of the bracket plate 102, one end of the rotating shaft 402 is connected to the output end of the motor 403, and the other end is fixedly connected to the toothed disc 401, the toothed disc 401 is meshed with the gear 303, a pin rod 201 is fixedly provided at an eccentric position on the side wall of the turntable 20, a non-return claw 203 is rotatably provided on the outside of the pin rod 201, the non-return claw 203 is obliquely extended from one end of the pin rod 201 to between two adjacent groups of teeth of the tooth plate 401, and one side of the non-return claw 203 is also connected to the side wall of the turntable 20 through a first elastic member 202.

[0038] When the gear 401 rotates in the opposite direction, the motor 403 drives the rotating shaft 402 to rotate in the opposite direction, thereby driving the toothed disc 401 to rotate in the opposite direction. When the toothed disc 401 rotates in the opposite direction, it drives the group of rolls 301 to rotate relative to the turntable 20 through the meshing action with the gear 303. When the group of rolls 301 rotates, the point-break type packaging bag film is rolled up; when the toothed disc 401 rotates in the opposite direction, it can push the check claw 203 so that the check claw 203 rotates adaptively compared to the pin 201, and the check claw 203 cannot limit the reverse rotation of the turntable 403; when the point-break type packaging bag film outside the group of rolls 301 is wound for a predetermined number of turns, the clamping assembly 50 clamps the subsequent point-break type packaging bag film. At this time, relying on the rotational power of the group of rolls 301, the point-break type packaging bag film outside the group of rolls 301 is The packaging bag film is disconnected from the subsequent point-break packaging bag film, and then the motor 403 drives the rotating shaft 402 to rotate forward, and then drives the toothed disc 401 to rotate forward. Since the end of the non-return claw 203 away from the pin rod 201 is inclined and extends to between two adjacent groups of teeth of the toothed disc 401, the non-return claw 203 can drive the turntable 20 to rotate relative to the corresponding bracket plate 102 when the toothed disc 401 rotates forward, thereby driving a number of rolls 301 to move in a circle, so as to turn the roll 301 wound with the point-break packaging bag film away from the winding station, and at the same time turn the latter group of rolls 301 to the winding station, and then the motor 403 drives the rotating shaft 402 to rotate in the opposite direction again, and then drives the toothed disc 401 to rotate in the opposite direction, and utilizes the meshing action of the toothed disc 401 and the gear 303 to drive the roll 301 turned to the winding station to rotate, and then continue to wind the subsequent point-break packaging bag film.

[0039] See also Figure 1 as well as Figure 4 In one embodiment, the clamping assembly 50 includes a U-shaped plate 501, a top cylinder 505, a rack 507 and a guide rod 509, wherein the guide rod 509 is fixedly mounted on the upper part of the support platform 10, the top cylinder 505 is sleeved on the upper end of the guide rod 509 and telescopically cooperates with the guide rod 509, the lower end of the top cylinder 505 is connected to the support platform 10 through a second elastic member 508, and the second elastic member 508 is used to provide elastic tension to the top cylinder 505, the U-shaped plate 501 is arranged on one side of the turntable 20, the bottom of the U-shaped plate 501 is fixedly connected to the support platform 10 through a support rod 502, a through hole 5011 is opened on the bottom wall of the U-shaped plate 501 for the top cylinder 505 to pass through, the rack 507 is arranged on the side of the U-shaped plate 501 and can mesh with the gear 303, and the rack 507 and the top cylinder 505 are connected by an L-shaped connecting rod 506.

[0040] When a group of rolls 301 moves in a circular motion to the winding station, the gear 303 and the rack 507 outside the group of rolls 301 are in a meshing state. When the motor 403 drives the toothed disc 401 to rotate in the opposite direction through the rotating shaft 402, the meshing action of the toothed disc 401 and the gear 303 drives the group of rolls 301 to rotate, so as to wind the point-break type packaging bag film. During the winding process of the point-break type packaging bag film, it passes through the inner side of the U-shaped plate 501, and the toothed disc 401 and the gear 303 are meshed to drive the roll 301 to rotate compared with the rotating disk 20. The gear 303 and the rack 507 are meshed to drive the rack 507 to move up. When the rack 507 moves up, the top cylinder 505 is driven to move up through the L-shaped connecting rod 506. When the roll 301 at the winding station winds the point-break type packaging bag film for a predetermined number of turns, the top cylinder 505 extends from the through hole 5011 The roll 301 is inserted into the inner side of the U-shaped plate 501, and then the subsequent point-break type packaging bag film is supported to achieve the clamping and limiting of the subsequent point-break type packaging bag film. At this time, as the roll 301 continues to rotate, the point-break type packaging bag film located outside the roll 301 is pulled and then disconnected from the subsequent point-break type packaging bag film. Then the motor 403 drives the toothed disc 401 to rotate forwardly through the rotating shaft 402, and then drives the turntable 20 to rotate through the cooperation with the check claw 203. The turntable 20 turns the roll 301 wound with the point-break type packaging bag film away from the winding station, and at the same time turns the latter group of rolls 301 to the winding station. When the above-mentioned roll 301 wound with the point-break type packaging bag film is turned away from the winding station, the gear 303 outside the roll 301 is separated from the rack 507, and the second elastic member 508 pulls the top cylinder 505 to move the top cylinder 505 downward, thereby achieving the resetting of the top cylinder 505.

[0041] See also Figure 3 In one embodiment, a plurality of evenly distributed air holes 302 are opened on the wall of the reel 301 , and a negative pressure fan 304 is provided at one end of the reel 301 away from the turntable 20 .

[0042] The inner cavity of the reel 301 is evacuated by the negative pressure fan 304, so that the outside air can enter the reel 301 through the plurality of air holes 302, and then the point-break type packaging bag film is adsorbed on the outside of the reel 301, so that the point-break type packaging bag film can be smoothly rolled up when the reel 301 rotates.

[0043] In one embodiment, the first elastic member 202 and the second elastic member 508 may be springs or metal springs, which are not limited herein.

[0044] See also Figure 1In one embodiment, a limiting plate 503 is fixedly provided on one side of the U-shaped plate 501, and the limiting plate 503 extends obliquely from one end of the U-shaped plate 501 to a position below the reel 301 at the winding station, and a slot 504 is opened on the limiting plate 503 for the reel 301 to pass through.

[0045] After the point-break packaging bag film on the outside of a group of rolls 301 is disconnected from the subsequent point-break packaging bag film, the disconnected point-break packaging bag film droops and adheres to the upper part of the limiting plate 503 in an inclined state. When the subsequent roll 301 performs a circular motion with the turntable 20, the subsequent roll 301 can pass through the slot 504 from bottom to top and act on the point-break packaging bag film on the upper part of the limiting plate 503, thereby lifting the point-break packaging bag film. At the same time, with the help of the suction effect of the negative pressure fan 304, the point-break packaging bag film is adsorbed on the outside of the roll 301, thereby realizing the continuation of the disconnected point-break packaging bag film and realizing the continuous and automatic winding of the point-break packaging bag film.

[0046] See also Figure 1 In one embodiment, a support leg 101 is fixedly provided on the bottom edge of the support platform 10 .

[0047] In the embodiment of the present invention, initially, a certain group of winding components 30 is at the winding station. When the point-break type packaging bag film needs to be wound up, the driving component 40 runs in the reverse direction to drive the plurality of winding components 30 to rotate compared to the turntable 20. The winding components 30 at the winding station wind the point-break type packaging bag film around the outside thereof. After the point-break type packaging bag film outside the group of winding components 30 is wound a predetermined number of times, the clamping component 50 clamps the subsequent point-break type packaging bag film. At this time, relying on the rotational power of the group of winding components 30, the point-break type packaging bag film outside the group of winding components 30 is disconnected from the subsequent point-break type packaging bag film. Then the driving component 40 moves forward, thereby driving the The rotating turntable 20 rotates a preset angle. When the rotating turntable 20 rotates a preset angle, it can drive several winding assemblies 30 to move in a circle at a preset angle, so that the winding assembly 30 wound with the discontinuous packaging bag film turns away from the current winding station, and at the same time makes the next group of winding assemblies 30 rotate to the winding station, and then the driving assembly 40 runs in the opposite direction again to drive the next group of winding assemblies 30 to rotate compared with the rotating turntable 20, and then the subsequent discontinuous packaging bag film is wound. Such a reciprocating cycle can realize the continuous automatic winding of the discontinuous packaging bag film. Compared with the prior art, it can realize the continuous automatic winding of the discontinuous packaging bag film, and has the advantages of good winding effect and high winding efficiency.

Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
