Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag production technology, and in particular to a plastic woven bag cutting and conveying device. Background Technology

[0002] Plastic woven bags, also known as cut fiber bags, are packaging products made by processing plastic raw materials into flat filaments through a specific production process, and then weaving them together. The main materials of plastic woven bags are polypropylene (PP) and polyethylene (PE). These two materials have good physical and chemical properties, which gives woven bags sufficient strength and durability.

[0003] For example, a plastic woven bag cutting machine disclosed in Chinese Patent No. CN220499359U has a collection device that uses a pressure plate to squeeze the processed plastic woven bags into a collection box for collection, thereby improving the efficiency of plastic woven bag production. When the plastic woven bags are pressed into the collection box, the pressure plate will continue to squeeze the plastic woven bags downward under the action of a hydraulic cylinder, making them squeezed together and increasing the space utilization of the collection box. However, this application has the following shortcomings: the plastic woven bags need to pass through blades during the conveying process, and these blades have no protective structure, which poses certain safety hazards when placing or picking up the plastic woven bags. Therefore, a plastic woven bag cutting and conveying device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a plastic woven bag cutting and conveying device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a plastic woven bag cutting and conveying device, including a device platform and support legs. Support legs are installed at the four corners of the bottom of the device platform. Support rods are symmetrically installed on the device platform. Fixing plates are symmetrically installed on each of the two support rods. A connecting rod is slidably connected to each fixing plate. A shielding strip is installed at one end of each connecting rod. A baffle is installed at the other end of each connecting rod, and a spring is sleeved on the connecting rod.

[0006] As a further technical solution of this utility model, one end of each spring abuts against the blocking strip, the other end of each spring abuts against the fixing plate, and each connecting rod is provided through the fixing plate.

[0007] As a further technical solution of this utility model, a horizontal plate is installed at the top of the two support rods, and telescopic cylinders are symmetrically installed on the horizontal plate. A strip plate is installed through the telescopic ends of the two telescopic cylinders, and a cutting blade is installed at the bottom of the strip plate.

[0008] As a further technical solution of this utility model, two shielding strips are provided in total, and the two shielding strips are symmetrically arranged on the bottom outer side of the cutting blade. A placement plate is installed between the two support rods at the bottom near the bottom position.

[0009] As a further technical solution of this utility model, the placement plate is provided with a cutting groove adapted to the cutting blade, the top of each of the two shielding strips on opposite sides is provided with a cutting bevel, and a fixing plate is installed on one side of the top of the device platform.

[0012] 1. This design discloses a plastic woven bag cutting and conveying device. It comprises a fixed plate, connecting rod, shielding strip, baffle, and spring. The shielding strip provides protection on both sides of the bottom of the cutting blade, preventing accidental contact with the cutting blade when the plastic woven bag is placed. When the cutting blade moves downward with the telescopic cylinder, it abuts against the shielding strip, compressing it. The connecting rod slides on the fixed plate, and the shielding strip compresses the spring, causing the cutting blade to move downward and cut the plastic woven bag. After the cutting blade returns to its original position, the spring force causes the shielding strip to return to its original position on both sides of the bottom of the cutting blade.

[0013] 2. This design provides a plastic woven bag cutting and conveying device. Through the setting of a placement plate, connecting rollers and conveying wheels, a drive motor drives multiple connecting rollers to rotate. When the connecting rollers rotate, the conveying wheels rotate, conveying the plastic woven bags on the device table. The plastic woven bags are conveyed through the placement plate. After the cutting blade cuts the plastic woven bags, the plastic woven bags are placed between the device table and the conveying wheels, and their position will not shift.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a cutting and conveying device for plastic woven bags, including a device platform 1 and support legs 2. Support legs 2 are installed at the four corners of the bottom of the device platform 1. Support rods 3 are symmetrically installed on the device platform 1. Fixing plates 14 are symmetrically installed on each of the two support rods 3. A connecting rod 15 is slidably connected to each fixing plate 14. A baffle strip 13 is installed at one end of each connecting rod 15, and a baffle plate 16 is installed at the other end of each connecting rod 15. A spring 17 is sleeved on each connecting rod 15, with one end of each spring 17 abutting against the baffle strip 13 and the other end abutting against the fixing plate 14. Each connecting rod 15 passes through the fixing plate 14. A cutting blade 7 is installed at the bottom of a strip plate 6. Two baffle strips 13 are provided. The two baffle strips 13 support each other. The cutting blade 7 is positioned on the bottom outer side of the cutting blade 7. A placement plate 8 is installed between the two support rods 3 near the bottom. The placement plate 8 has a cutting groove that matches the cutting blade 7. The top of each of the two shielding strips 13 on opposite sides has a cutting bevel. The telescopic cylinder 5 drives the cutting blade 7 to move up and down to cut the plastic woven bag. When the cutting blade 7 moves downward, it abuts against the inclined surface of the shielding strip 13. After passing the inclined surface, it squeezes the shielding strip 13. The connecting rod 15 slides on the fixing plate 14. The shielding strip 13 squeezes the spring 17, and the cutting blade 7 moves downward to cut the plastic woven bag. When the cutting blade 7 moves upward, it no longer squeezes the shielding strip 13. The elastic force of the spring 17 causes the shielding strip 13 to return to its original position on both sides of the bottom of the cutting blade 7, thus shielding and protecting the cutting blade 7.

[0021] like Figure 1 and Figure 2As shown, a horizontal plate 4 is installed at the top of the two support rods 3. Telescopic cylinders 5 are symmetrically installed on the horizontal plate 4. The telescopic ends of the two telescopic cylinders 5 pass through the horizontal plate 4 and are installed with strip plates 6. A fixed plate 9 is installed on one side of the top of the device platform 1. Multiple connecting rollers 11 are rotatably installed on both fixed plates 9. Each connecting roller 11 is equipped with a conveyor wheel 12. The conveyor wheel 12 is made of rubber to facilitate the conveying of plastic woven bags on the device platform 1. A drive motor 10 is installed on both fixed plates 9. The power output end of the drive motor 10 is fixedly connected to a connecting roller 11. The fixed plate 9 has a connecting structure inside to drive the connection between each connecting roller 11, so that each conveyor wheel 12 rotates to convey the plastic woven bags.

[0022] The working principle of this utility model is as follows: The plastic woven bag is passed between the conveyor wheel 12 on the device platform 1 and a fixed plate 9, and then passes through the placement plate 8, and abuts against the conveyor wheel 12 on another fixed plate 9. The conveyor wheel 12 conveys the plastic woven bag on the device platform 1. When it needs to be cut, the telescopic cylinder 5 drives the cutting blade 7 to move downward. When the cutting blade 7 moves downward, it abuts against the inclined surface of the shielding strip 13. After passing the inclined surface, it squeezes the shielding strip 13. The connecting rod 15 slides on the fixed plate 14. The shielding strip 13 squeezes the spring 17, cutting the plastic woven bag. The telescopic cylinder 5 drives the cutting blade 7 to move upward, no longer squeezing the shielding strip 13. The elastic force of the spring 17 causes the shielding strip 13 to return to its original position and move to both sides of the bottom of the cutting blade 7, shielding and protecting the cutting blade 7.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
