Technical Field

[0001] This utility model relates to the field of packaging bag production technology, and in particular to a packaging bag production film roll feeding device. Background Technology

[0002] Rolls of plastic film are required as raw material in the production of packaging bags. These rolls are quite heavy, and existing feeding devices for packaging bag production require manual labor to lift and load a new roll after each use, which is very labor-intensive. Therefore, there is an urgent need to develop a packaging bag production film roll feeding device that is easy to replace and saves manpower, overcoming the shortcomings of current applications and meeting current needs. Utility Model Content

[0003] The purpose of this utility model is to provide a film roll feeding device for packaging bag production, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A film roll feeding device for packaging bag production includes a frame, bases, sleeves, a first motor, a bidirectional moving mechanism, and an auxiliary feeding mechanism. Two bases are mounted on the frame, and a bidirectional moving mechanism is installed on the frame to drive the two bases to move towards each other. Two sleeves are included: one sleeve is rotatably connected to the base located on the right half of the frame, and the first motor is fixed to the base located on the left half of the frame. The output shaft of the first motor is fixed to one sleeve via a coupling. Each sleeve is fitted with a fastening bolt extending into its interior. The rear side of the base is adjacent to the frame. An auxiliary feeding mechanism is installed on the machine frame. The auxiliary feeding mechanism includes a lead screw, a synchronous pulley, a synchronous belt, a third motor, a threaded block, and a lifting plate. Two lead screws are rotatably connected to the frame. A synchronous pulley is fixed at the upper end of each lead screw. The two synchronous pulleys are connected by a synchronous belt. The third motor is fixed to the frame. The output shaft of the third motor is fixed to one of the lead screws. A threaded block is installed on each lead screw. A lifting plate is fixedly connected between two threaded blocks. The right half of the lifting plate is provided with a feeding ramp, and the left half of the lifting plate is provided with a positioning groove.

[0006] Preferably, each of the bases has two sliders fixed to its bottom, and the frame has two linear slide rails fixed to it, with the sliders slidably mounted on the linear slide rails.

[0007] Preferably, the bidirectional moving mechanism includes: a second motor, a bidirectional screw, a first external thread, a second external thread, a first threaded sleeve, and a second threaded sleeve. The second motor is fixed to the frame, the bidirectional screw is rotatably connected to the frame, the output shaft of the second motor is fixed to the bidirectional screw, the left half of the bidirectional screw is provided with a first external thread, a first threaded sleeve that mates with the first external thread is installed on the outside of the first external thread, the right half of the bidirectional screw is provided with a second external thread, a second threaded sleeve that mates with the second external thread is installed on the outside of the second external thread, and the first threaded sleeve and the second threaded sleeve are respectively fixed to the base.

[0008] Preferably, the first external thread and the second external thread have opposite directions of rotation.

[0009] The beneficial effects of this utility model are as follows: In use, the packaging bag production film roll feeding device uses a first motor to drive a sleeve to rotate, which in turn drives a storage roller to rotate, causing the storage roller to convey the plastic film wound on it outwards. When the plastic film on the storage roller is used up, it needs to be replaced. To replace it, first loosen the fastening bolts to release the two ends of the storage roller. Then, a second motor drives a bidirectional screw to rotate, which in turn drives the first and second threaded sleeves to move towards each other. The first and second threaded sleeves then drive the two bases to move towards each other, and the bases then drive the two sleeves to move towards each other. The two bases are moved apart to remove the storage roller. Then, the lifting plate is lowered to its lowest point, so that the bottom end of the feeding ramp touches the ground. The new storage roller rolls from the ground along the feeding ramp into the positioning groove. Then, the third motor drives the lead screw to rotate, which in turn moves the lifting plate upward, moving the new storage roller to the sleeve. Then, the two bases are moved closer together by the bidirectional moving mechanism, so that the two sleeves are moved closer together, allowing both ends of the storage roller to be inserted into the two sleeves. Finally, the fastening bolts are tightened to clamp the ends of the storage roller. The lifting plate is then lowered to the ground to complete one replacement. In summary, this utility model is convenient for replacement and saves manpower. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] See Figures 1-5 In this embodiment of the present invention, a film roll feeding device for packaging bag production includes a frame 1, a base 2, a sleeve 3, a first motor 4, a storage roller 5, a bidirectional moving mechanism 6, and an auxiliary feeding mechanism 7. Two bases 2 are mounted on the frame 1, and two sliders 201 are fixed to the bottom of each base 2. Two linear slide rails 202 are fixed on the frame 1, and the sliders 201 are slidably mounted on the linear slide rails 202. A bidirectional moving mechanism 6 is mounted on the frame 1 to drive the two bases 2 to move towards each other. There are two cylinders 3. A sleeve 3 is rotatably connected to the base 2 located on the right half of the frame 1. A first motor 4 is fixed on the base 2 located on the left half of the frame 1. The output shaft of the first motor 4 is fixed to a sleeve 3 through a coupling. Each sleeve 3 is equipped with a fastening bolt 301 extending into it. A storage roller 5 is detachably installed between the two sleeves 3. The storage roller 5 is wrapped with plastic film for producing plastic bags. An auxiliary feeding mechanism 7 is installed on the rear side of the base 2 on the frame 1.

[0020] The bidirectional moving mechanism 6 includes: a second motor 601, a bidirectional screw 602, a first external thread 603, a second external thread 604, a first threaded sleeve 605, and a second threaded sleeve 606. The second motor 601 is fixed to the frame 1. The bidirectional screw 602 is rotatably connected to the frame 1. The output shaft of the second motor 601 is fixed to the bidirectional screw 602. The left half of the bidirectional screw 602 is provided with the first external thread 603, and a first threaded sleeve 605 is installed on the outer side of the first external thread 603 to mate with it. The right half of the bidirectional screw 602 is provided with the second external thread 604. A second threaded sleeve 606 is installed on the outer side of the external thread 604 to mate with it. The first threaded sleeve 605 and the second threaded sleeve 606 are fixed to the base 2 respectively. The first external thread 603 and the second external thread 604 have opposite directions of rotation, so that the first threaded sleeve 605 and the second threaded sleeve 606 move in opposite directions when the bidirectional screw 602 rotates. In use, the second motor 601 drives the bidirectional screw 602 to rotate, and the rotation of the bidirectional screw 602 drives the first threaded sleeve 605 and the second threaded sleeve 606 to move towards each other. The first threaded sleeve 605 and the second threaded sleeve 606 drive the two bases 2 to move towards each other.

[0021] The auxiliary feeding mechanism 7 includes: a lead screw 701, a synchronous pulley 702, a synchronous belt 703, a third motor 704, a threaded block 705, and a lifting plate 706. Two lead screws 701 are rotatably connected to the frame 1. Each lead screw 701 has a synchronous pulley 702 fixed at its upper end. The two synchronous pulleys 702 are connected by a synchronous belt 703. The third motor 704 is fixed to the frame 1. The output shaft of the third motor 704 is fixed to one lead screw 701. Each lead screw 701 is equipped with a threaded block 705. A lifting plate 706 is fixedly connected between two threaded blocks 705. The right half of the lifting plate 706 is provided with a feeding inclined surface 7061, and the left half of the lifting plate 706 is provided with a positioning groove 7062. In use, the third motor 704 drives the lead screw 701 to rotate, and the rotation of the lead screw 701 drives the lifting plate 706 to move up and down.

[0022] Working Principle: This packaging bag production film roll feeding device operates by using a first motor 4 to rotate a sleeve 3, which in turn rotates a storage roller 5, causing the storage roller 5 to feed the plastic film wound on it outwards. When the plastic film on the storage roller 5 is used up, it needs to be replaced. To replace it, first loosen the fastening bolt 301 to release the two ends of the storage roller 5. Then, a second motor 601 drives a bidirectional screw 602 to rotate, which in turn moves the first threaded sleeve 605 and the second threaded sleeve 606 towards each other. This movement in turn moves the two bases 2 towards each other, and the bases 2 move the two sleeves 3 away from each other, thus feeding the storage roller 5. Remove the material roller 5, then lower the lifting plate 706 to the lowest point so that the bottom end of the feeding ramp 7061 touches the ground. Then, roll the new storage roller 5 from the ground along the feeding ramp 7061 into the positioning groove 7062. Then, drive the lead screw 701 to rotate through the third motor 704. The rotation of the lead screw 701 drives the lifting plate 706 to move upward, so that the new storage roller 5 moves to the sleeve 3. Then, drive the two bases 2 to move closer to each other through the bidirectional moving mechanism 6, so that the two sleeves 3 move closer to each other, so that the two ends of the storage roller 5 are inserted into the two sleeves 3. Then tighten the fastening bolts 301 to clamp the ends of the storage roller 5. Finally, lower the lifting plate 706 to the ground to complete one replacement.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
