A sewing device for woven bag production

Abstract

This utility model relates to the field of woven bag sewing technology, specifically a sewing device for woven bag production. The device includes an operating plate with a limit block fixedly connected to its upper end and a fixing block fixedly connected to its upper end. An electric telescopic rod is fixedly connected to the front of the fixing block. A vertical plate is fixedly connected to the upper end of the operating plate. By activating a cylinder located at the upper end of the vertical plate, the cylinder drives a connecting rod to move up and down on the surface of the vertical plate. This causes a push rod to drive a pressing plate to move up and down repeatedly at the lower end of the vertical plate, thereby moving the operating cylinder towards the part of the woven bag that needs to be sewn until the sewing needle at the top of the push rod contacts the woven bag, thus completing the sewing work. At this time, a sliding plate will compress a telescopic spring at the bottom of the inner wall of the operating cylinder, causing the telescopic spring to deform, thereby improving the sewing effect of the sewing needle and improving the quality of the resulting woven bag.

Description

Technical Field

[0001] This utility model relates to the field of woven bag sewing technology, specifically a sewing device for woven bag production. Background Technology

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally polyethylene, polypropylene, and other chemical plastics. Weaving density refers to the number of warp and weft yarns within a 100mm x 100mm woven fabric. Woven plastic materials are used in tourism for temporary tents, parasols, various travel bags, and travel pouches. Various tarpaulins are widely used as covering materials for transportation and storage, replacing the easily moldy and heavy cotton tarpaulins. Construction fencing and netting also widely utilize woven plastic materials. Common types include logistics bags, logistics packaging bags, freight bags, and freight packaging bags.

[0003] The existing authorization announcement number CN216838470U discloses a sewing device for woven bag production, including a base plate, with a housing fixedly connected to both sides of the base plate. A stepper motor is fixedly connected to the inner side of the inner cavity of the housing. The output shaft of the stepper motor is horizontally arranged and coaxially fixedly connected to a rotating shaft. A worm gear is sleeved on the outer side of the rotating shaft. A worm is meshed on the surface of the worm gear. A screw is fixedly connected to the top of the worm. A threaded sleeve is threaded to the bottom of the surface of the screw.

[0004] The aforementioned device adjusts the height of the sewing device by activating the stepper motor, which in turn drives a rotating shaft. This shaft, in turn, drives a worm gear, which in turn drives a worm, which in turn drives a screw. Both the worm and screw rotate simultaneously via bearing seats. However, since the sewing device prioritizes the positioning and fixing of the woven bags, and since there are multiple types of woven bags to be sewn, this priority is crucial for improving the quality of the finished sewn bags. Therefore, we propose a sewing device for woven bag production. Utility Model Content

At this time, the rotating plate is rotated, and the rotating plate will drive the rotating rod inside the rotating groove to rotate, thereby realizing the displacement and rotation of the rotating plate towards the surface of the production plate, so that the locking post on the front of the movable plate is locked with the woven bag, thereby completing the limiting and fixing of the front end of the woven bag. Then, the telescopic post under the rotating rod is extended and retracted, thereby completing the limiting and fixing of the rear end of the woven bag, thus preparing for the subsequent sewing work.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a sewing device for woven bag production includes an operation plate 1, a limiting block 11 fixedly connected to the upper end of the operation plate 1, a fixing block 12 fixedly connected to the upper end of the operation plate 1, an electric telescopic rod 13 fixedly connected to the front of the fixing block 12, and a vertical plate 14 fixedly connected to the upper end of the operation plate 1. It also includes a limiting mechanism 2, which includes a slide 29 opened at the upper end of the operation plate 1. A slider 28 is slidably connected to the bottom of the inner wall of the slide 29. A production plate 21 is fixedly connected to the end of the slider 28 away from the slide 29. A limiting platform 25 is fixedly connected to the upper end of the production plate 21, and a telescopic locking post is fixedly connected to the inner wall of the limiting platform 25.

[0025] The production plate 21 has a position sensor 22 fixedly connected to its inner wall. The inner wall surface of the production plate 21 has a rotating groove. The inner wall of the rotating groove has a fixed column 23 fixedly connected to it. The end of the fixed column 23 away from the rotating groove is rotatably connected to a rotating rod 24. The position sensor 22 is an LT-M displacement sensor, which can effectively select the appropriate position for sewing the woven bag.

[0026] A rotating plate 26 is fixedly connected to the surface of the rotating rod 24. A movable plate 27 is rotatably connected to the rotating plate 26. A locking post is fixedly connected to the front of the movable plate 27. There are two rotating plates 26, which are symmetrically arranged about the center of the production plate 21. The woven bag to be sewn is placed inside the production plate 21 and passes through the limiting platform 25 first. Then, its top end contacts the top end of the production plate 21. At this time, rotating the rotating plate 26 will drive the rotating rod 24 inside the rotating groove to rotate, thereby realizing the displacement and rotation of the rotating plate 26 towards the surface of the production plate 21. This causes the locking post on the front of the movable plate 27 to engage with the woven bag, thus completing the limiting and fixing of the front end of the woven bag. Then, the telescopic post below the rotating rod 24 extends and retracts, thereby completing the limiting and fixing of the rear end of the woven bag, thus preparing for the subsequent sewing work.

[0027] The upper end of the upright plate 14 is provided with a pushing mechanism 3, which includes a docking plate 31 fixedly connected to the upper end of the upright plate 14, a cylinder 32 fixedly connected to the upper end of the docking plate 31, and a docking rod 33 fixedly connected to the upper end of the docking plate 31.

[0028] The cylinder 32 has two docking plates 31, which are symmetrically arranged about the center of the cylinder 32. There are several docking rods 33, which are fixedly connected to the cylinder 32. A push rod 34 is fixedly connected to the lower end of the cylinder 32. The push rod 34 passes through the vertical plate 14. A push plate 35 is fixedly connected to the end of the push rod 34 away from the cylinder 32. By activating the cylinder 32 located at the upper end of the vertical plate 14, the cylinder 32 will drive the docking rods 33 to move up and down on the surface of the vertical plate 14, thereby causing the push rod 34 to drive the push plate 35 to move up and down repeatedly at the lower end of the vertical plate 14.

[0029] The lower end of the push plate 35 is provided with a sewing mechanism 4. The sewing mechanism 4 includes an operating cylinder 41 fixedly connected to the lower end of the push plate 35. A telescopic spring 42 is fixedly connected to the bottom of the inner wall of the operating cylinder 41. A sliding plate 43 is provided at the end of the telescopic spring 42 away from the bottom of the inner wall of the operating cylinder 41.

[0030] The sliding plate 43 is slidably connected to the inner wall of the operating cylinder 41. A top rod 44 is fixedly connected to the end of the sliding plate 43 away from the telescopic spring 42. A sewing needle 45 is fixedly connected to the end of the top rod 44 away from the sliding plate 43. The number of operating cylinders 41 is set to several, and all of the operating cylinders 41 are fixedly connected to the lower end of the push plate 35. By pushing the cylinder 32, the operating cylinder 41 will move towards the part of the woven bag that needs to be sewn until the sewing needle 45 at the top of the top rod 44 contacts the woven bag, thereby completing the sewing work. At this time, the sliding plate 43 will squeeze the telescopic spring 42 at the bottom of the inner wall of the operating cylinder 41, thereby deforming the telescopic spring 42, which can make the sewing effect of the sewing needle 45 better, thereby improving the quality of the obtained woven bag.

[0031] This utility model provides a sewing device for woven bag production, the specific working principle of which is as follows:

[0032] In use, the user places the woven bag to be sewn inside the production plate 21, allowing it to pass first through the limiting platform 25, and then its top contact with the top of the production plate 21. At this point, rotating the rotating plate 26 causes the rotating rod 24 inside the rotating groove to rotate, thus displacing the rotating plate 26 towards the surface of the production plate 21. This causes the locking post on the front of the movable plate 27 to engage with the woven bag, thus fixing the front end of the woven bag. Subsequently, the telescopic post below the rotating rod 24 extends or retracts, thus fixing the rear end of the woven bag, preparing for subsequent sewing. After preparation, the cylinder 32 located at the upper end of the upright plate 14 is activated. The cylinder 32 will drive the docking rod 33 to move up and down on the surface of the upright plate 14, thereby causing the push rod 34 to drive the push plate 35 to move up and down repeatedly at the lower end of the upright plate 14. This will cause the operating cylinder 41 to move towards the part of the woven bag that needs to be sewn, until the sewing needle 45 at the top of the push rod 44 contacts the woven bag, thus completing the sewing work. At this time, the sliding plate 43 will squeeze the telescopic spring 42 at the bottom of the inner wall of the operating cylinder 41, thereby deforming the telescopic spring 42, which can make the sewing effect of the sewing needle 45 better, thereby improving the quality of the obtained woven bag.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
