Description

Technical Field

[0001] This utility model relates to the technical field of plastic film sewing equipment, and more specifically, to a sewing device for producing polypropylene film ton bags. Background Technology

[0002] A ton bag is a medium-sized bulk container, usually made of high-strength materials such as polypropylene and polyethylene. Ton bags are characterized by large capacity, strong load-bearing capacity, and easy loading and unloading. In addition, ton bags can be reused, which can effectively reduce packaging costs. Therefore, they are widely used in logistics and transportation, chemical, building materials, and food industries.

[0003] When operators produce polypropylene film ton bags, they often use sewing devices to sew several pieces of polypropylene film together. However, while existing sewing devices have basic sewing functions, they generally fix the sewing machine in the device and cannot be replaced. When the sewing machine malfunctions, the entire sewing device becomes unusable. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a sewing device for the production of polypropylene film ton bags, which has the advantage of replaceable sewing machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewing device for producing polypropylene film ton bags, comprising a processing table, a connecting column fixedly connected to the rear side of the upper surface of the processing table, an mounting plate movably sleeved on the outer surface of the connecting column, a movable plate movably connected to the inner surface of the mounting plate, a sewing machine movably connected to the front side of the upper surface of the movable plate, mounting blocks fixedly connected to the outer surfaces of both sides of the sewing machine, movable blocks movably connected to the outer surfaces of the mounting blocks, and the outer surfaces of the movable blocks movably connected to the outer surfaces of the sewing machine, a first motor fixedly installed on the rear side of the upper surface of the movable plate, a round shaft fixedly sleeved at the other end of the output shaft of the first motor, a gear fixedly sleeved on the outer surface of the round shaft, a toothed plate meshing with the outer surface of the gear, two toothed plates, a connecting plate fixedly connected to the upper surface of both toothed plates, and the outer surfaces of the connecting plates fixedly connected to the outer surfaces of the movable blocks.

[0006] As a preferred embodiment of this utility model, the outer surface of the movable block is movably connected to a limiting plate, the outer surfaces of the two toothed plates are movably connected to limiting blocks, and the lower surfaces of the limiting plate and the limiting blocks are fixedly connected to the upper surface of the movable plate.

[0007] As a preferred embodiment of this utility model, a fixing plate is fixedly sleeved on the top of the outer surface of the connecting column, and a pneumatic cylinder is fixedly installed on the upper surface of the fixing plate. The bottom end of the pneumatic cylinder penetrates the fixing plate and extends to the upper surface of the mounting plate and is fixedly connected to the mounting plate.

[0008] As a preferred embodiment of this utility model, a support plate is fixedly connected to the lower surface of the processing table, a base plate is fixedly connected to the bottom end of the support plate, a second motor is fixedly installed in the middle of the upper surface of the base plate, and a rotating shaft is fixedly sleeved at the other end of the output shaft of the second motor.

[0009] As a preferred embodiment of this utility model, a cam is fixedly sleeved on the outer surface of the rotating shaft, a connecting frame is movably connected to the top of the outer surface of the cam, and limiting sleeves located on the left and right sides of the processing table are movably connected to the outer surface of the connecting frame. The outer surface of the limiting sleeves is fixedly connected to the outer surface of the processing table, and a pressure plate is fixedly connected to the top of the connecting frame.

[0010] As a preferred embodiment of this utility model, a compression spring is fixedly connected to the lower surface of the processing table, and the bottom end of the compression spring is fixedly connected to the outer surface of the connecting frame.

[0011] As a preferred technical solution of this utility model, a No. 3 motor is fixedly installed on the right surface of the mounting plate, and a lead screw is fixedly sleeved on the other end of the output shaft of the No. 3 motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a sewing machine, mounting block, movable block, toothed plate and connecting plate, when the No. 1 motor starts running, the round shaft and gear will start to rotate. Due to the meshing between the outer surfaces of the gear and the toothed plate, the two toothed plates will start to move in opposite directions under the limit of the limiting block. During this process, the two movable blocks will start to disengage from the outer surface of the mounting block under the drive of the two connecting plates. Finally, when the mounting block leaves the inner surface of the movable block, the fixation between the sewing machine and the mounting block will be released. At this time, the operator can directly remove the entire sewing machine for replacement.

[0014] 2. This utility model, by setting up a cam, connecting frame, compression spring, limiting sleeve and pressure plate, when the No. 2 motor is running, the rotating shaft and cam will start to rotate. As the cam rotates, the connecting frame as a whole will move downward under the elastic force of the compression spring and the limiting force of the inner surface of the limiting sleeve. Finally, the four pressure plates will clamp the two polypropylene films, thereby ensuring that the two polypropylene films cannot move during the sewing process and ensuring the stability of the sewing quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a sewing device for producing polypropylene film ton bags, including a processing table 1. A connecting column 2 is fixedly connected to the rear side of the upper surface of the processing table 1. An installation plate 3 is movably sleeved on the outer surface of the connecting column 2. A movable plate 4 is movably connected to the inner surface of the installation plate 3. A sewing machine 5 is movably connected to the front side of the upper surface of the movable plate 4. Installation blocks 6 are fixedly connected to the outer surfaces of both sides of the sewing machine 5. Movable blocks 7 are movably connected to the outer surface of the installation blocks 6. The outer surface of the movable blocks 7 is movably connected to the outer surface of the sewing machine 5. A first motor 9 is fixedly installed on the rear side of the upper surface of the movable plate 4. A round shaft 10 is fixedly sleeved at the other end of the output shaft of the first motor 9. A gear 11 is fixedly sleeved on the outer surface of the round shaft 10. A toothed plate 12 is meshed with the outer surface of the gear 11. There are two toothed plates 12. A connecting plate 13 is fixedly connected to the upper surface of both toothed plates 12. The outer surface of the connecting plate 13 is fixedly connected to the outer surface of the movable block 7.

[0024] The operation of motor 9 will cause the circular shaft 10 and gear 11 to start rotating. Since gear 11 meshes with gear plate 12, the rotation of gear 11 will drive gear plate 12, causing the two gear plates 12, the two connecting plates 13 and the two movable blocks 7 to start moving in opposite directions.

[0025] Among them, the outer surface of the movable block 7 is movably connected to the limiting plate 8, the outer surfaces of the two toothed plates 12 are movably connected to the limiting block 14, and the lower surfaces of the limiting plate 8 and the limiting block 14 are fixedly connected to the upper surface of the movable plate 4.

[0026] The design of the limiting plate 8 and the limiting block 14 respectively limits the movement of the movable block 7 and the toothed plate 12.

[0027] Among them, a fixing plate 15 is fixedly sleeved on the top of the outer surface of the connecting column 2, and a pneumatic cylinder 16 is fixedly installed on the upper surface of the fixing plate 15. The bottom end of the pneumatic cylinder 16 passes through the fixing plate 15 and extends to the upper surface of the mounting plate 3 and is fixedly connected to the mounting plate 3.

[0028] The operation of the pneumatic cylinder 16 will cause the mounting plate 3 to move downwards as a whole.

[0029] Among them, a support plate 17 is fixedly connected to the lower surface of the processing table 1, a base plate 18 is fixedly connected to the bottom end of the support plate 17, a second motor 19 is fixedly installed in the middle of the upper surface of the base plate 18, and a rotating shaft 20 is fixedly sleeved at the other end of the output shaft of the second motor 19.

[0030] When motor 19 is running, the rotating shaft 20 will start to rotate.

[0031] Among them, a cam 21 is fixedly sleeved on the outer surface of the rotating shaft 20, a connecting frame 22 is movably connected to the top of the outer surface of the cam 21, a limiting sleeve 24 located on the left and right sides of the processing table 1 is movably connected to the outer surface of the connecting frame 22, the outer surface of the limiting sleeve 24 is fixedly connected to the outer surface of the processing table 1, and a pressure plate 25 is fixedly connected to the top of the connecting frame 22.

[0032] When the cam 21 rotates, the connecting frame 22 as a whole will start to move up and down under the limit of the limiting sleeve 24.

[0033] Among them, a compression spring 23 is fixedly connected to the lower surface of the processing table 1, and the bottom end of the compression spring 23 is fixedly connected to the outer surface of the connecting frame 22.

[0034] Under the elastic force of the compression spring 23, the connecting frame 22 and the pressure plate 25 will automatically move downward, so that the four pressure plates 25 will clamp the two polypropylene films respectively.

[0035] Among them, the right surface of the mounting plate 3 is fixedly mounted with a No. 3 motor 26, and the other end of the output shaft of the No. 3 motor 26 is fixedly sleeved with a lead screw 27. The left end of the lead screw 27 passes through the mounting plate 3 and the moving plate 4 in sequence and extends to the left side of the mounting plate 3. The outer surface of the lead screw 27 and the inner surface of the moving plate 4 are threaded together.

[0036] When motor 26 is running, lead screw 27 will begin to rotate.

[0037] Working principle and usage process of this utility model:

[0038] When the operator begins to sew the two polypropylene films together, the operator first starts motor 19. As motor 19 runs, the rotating shaft 20 and cam 21 will start to rotate. At this time, the rotation of cam 21 will cause the connecting frame 22 and pressure plate 25 to move downward under the elastic force of the compression spring 23, and finally clamp the two polypropylene films.

[0039] When the sewing machine 5 is damaged, the operator starts the first motor 9. As the first motor 9 runs, the round shaft 10 and the gear 11 will start to rotate. At this time, the two toothed plates 12 will move in opposite directions under the drive of the gear 11 and the limit block 14. The movement of the two connecting plates 13 will drive the two movable blocks 7 respectively, so that the two movable blocks 7 will start to move in opposite directions along the inner surface of the limit plate 8. Finally, when the mounting block 6 is disengaged from the inner surface of the movable block 7, the sewing machine 5 and the mounting block 6 will be released. At this time, the operator can directly replace the entire sewing machine 5.
