Technical Field

[0001] The utility model relates to the technical field of automatic bag sewing machines, and particularly relates to a guiding mechanism for an automatic bag sewing machine. Background Art

[0002] An automatic bag sewing machine is an industrial machine used to automatically complete the sewing work of bags. It is commonly found in the packaging processes of industries such as grains, chemical raw materials, and building materials. This machine can significantly improve packaging efficiency, reduce labor costs, and ensure the consistency of sewing quality. The working principle of the automatic bag sewing machine is that through programming control, it can automatically complete the processes of feeding the bag, sewing, cutting the thread end, and discharging the finished bag without manual intervention. Moreover, the automatic bag sewing machine is applicable to bags of various materials and sizes, such as plastic bags, paper bags, cloth bags, etc.

[0003] When a traditional automatic bag sewing machine transports a packaging bag to the bag sewing machine, a guiding mechanism is often required to keep the sealing opening of the packaging bag basically consistent with the processing position of the bag sewing machine. However, during bag sewing, there may be wrinkles at the bag mouth of the packaging bag, which seriously affects the bag sewing operation of the bag sewing machine.

[0004] In view of this, a guiding mechanism for an automatic bag sewing machine is proposed. Summary of the Utility Model

[0032] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0033] Please refer to Figures 1-8 。

[0034] The guiding mechanism of the automatic bag sewing machine of the present utility model includes a conveyor belt 1, a bag sewing assembly 2 arranged downstream of the conveyor belt 1, and a guiding assembly 3 arranged upstream of the conveyor belt 1. The guiding assembly 3 further includes: a guiding member 31, the guiding member 31 includes two mounting frames 311 fixedly connected to both sides of the conveyor belt 1, a first guiding plate 312 arranged in the middle of the mounting frame 311 for guiding the body 41 of the packaging bag 4, and a second guiding plate 313 arranged at the top of the mounting frame 311 for guiding the sealing opening 42 of the packaging bag 4. The guiding member 31 is used to guide the packaging bag 4 to be in the middle of the conveyor belt 1 for subsequent bag sewing; an adjusting member 32, the adjusting member 32 includes two mounting seats 321 fixedly connected to both sides of the conveyor belt 1, a translation plate 322 slidably arranged on the mounting seats 321, and a clamping plate 326 slidably arranged on the translation plate 322. The adjusting member 32 is used to lift the sealing opening 42 of the packaging bag 4 for subsequent bag sewing operations; a flattening member 33, the flattening member 33 includes two vertical rods 331 fixedly connected to both sides of the conveyor belt 1, a flattening plate 332 fixedly connected to the top of the vertical rods 331, and a plurality of flattening wheels 333 rotatably connected to the flattening plate 332. The flattening member 33 is used to flatten the sealing opening 42 of the packaging bag 4 to prevent wrinkles from appearing in the sealing opening 42 of the packaging bag 4 during bag sewing.

[0035] That is to say, the guiding member 31 is used to adjust the position of the packaging bag 4 on the conveyor belt 1, the adjusting member 32 is used to adjust the position of the sealing opening 42 of the packaging bag 4, and the flattening member 33 is used to flatten the sealing opening 42 of the packaging bag 4 for subsequent bag sewing.

[0036] Specifically, a first sliding groove 325 is formed in the mounting base 321. A first sliding block 324 that matches the size of the first sliding groove 325 is fixedly connected to the bottom of the translation plate 322. An electric push rod 323 is fixedly connected to the mounting base 321. The extending end of the electric push rod 323 is fixedly connected to the translation plate 322. The electric push rod 323 is used to drive the translation plate 322 to move along the first sliding groove 325. A second sliding groove 329 is formed in the translation plate 322. A second sliding block 328 whose size is adapted to the second sliding groove 329 is slidably arranged in the second sliding groove 329. An electric telescopic plate 327 is fixedly connected to the second sliding block 328. One end of the electric telescopic plate 327 is fixedly connected to the second sliding block 328, and the other end of the electric telescopic plate 327 is fixedly connected to the clamping plate 326.

[0037] In addition, a motor 3303 is fixedly connected to the translation plate 322. The output end of the motor 3303 is fixedly connected to a screw rod 3301. The bottom of the screw rod 3301 is rotatably connected to the mounting base 321. A screw sleeve 3302 is threadedly connected to the screw rod 3301. The screw sleeve 3302 is rotatably connected to the second sliding block 328. The motor 3303 is used to drive the screw rod 3301 to rotate when starting, so as to drive the second sliding block 328 to slide along the second sliding groove 329 under the meshing action of the screw rod 3301 and the screw sleeve 3302.

[0038] That is to say, when the motor 3303 rotates, the screw rod 3301 rotates accordingly. Since the screw sleeve 3302 is threadedly connected to the screw rod 3301 and the screw sleeve 3302 is rotatably connected to the second sliding block 328, the screw sleeve 3302 can drive the second sliding block to move up and down along the second sliding groove 329.

[0039] In addition, the height of the second guide plate 313 is the same as the height of the flat plate 332. And the first sliding block 324 is arranged in an inverted T shape to keep the translation plate 322 stable, while the second sliding block 328 is arranged in a cross shape, and the second sliding block 328 penetrates the translation plate 322 in the horizontal direction.

[0040] It should be noted that the initial height of the clamping plate 326 should be the same as the initial height of the sealing opening 42 of the packaging bag 4 to be conveyed. That is to say, when a packaging bag 4 passes through the guiding component 31, the motor 3303 should rotate to make the clamping plate 326 and the sealing opening 42 of the packaging bag 4 at the same height. Subsequently, the electric telescopic plate 327 pushes out the clamping plate 326, so that the clamping plates 326 on both sides clamp and lift the sealing opening 42 of the packaging bag 4. During this process, the electric push rod 323 continuously contracts, and the contraction speed should be consistent with the conveying speed of the conveyor belt until the packaging bag 4 is conveyed to the flattening component 33. The clamping plate 326 should return to the initial position until the next packaging bag 4 is adjusted.

[0041] It should be noted that if the height of the packaging bag 4 after passing through the guiding member 31 is basically the same as the height of the flat plate 332, the adjusting member 32 may not work, that is to say, the adjusting member 32 is only used to adjust the packaging bag 4 whose sealing opening 42 is shrunk to a height lower than that of the flat plate 332.

[0042] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
