Description

Technical Field

[0001] This utility model relates to the field of glove production technology, specifically to a nitrile glove packaging device. Background Technology

[0002] Nitrile gloves are made from butadiene and acrylonitrile via emulsion polymerization. They exhibit excellent oil resistance, high abrasion resistance, and good heat resistance. Nitrile gloves are widely used in household chores, electronics, chemical, aquaculture, glass, food processing, and other industries for protective purposes, as well as in hospitals and scientific research. After production, the finished nitrile gloves are packaged in bags.

[0003] The basic process of existing packaging equipment involves opening the bag opening and then conveying nitrile gloves into the bag. During this process, a pneumatic adsorption component is used to adsorb the top of the bag to open it. However, since the bags are mostly made of PE (polyethylene) composite film with a thickness of 0.08-0.15mm, they have a certain degree of elasticity and flexibility and are prone to adhesion due to static electricity. Adsorption on one side cannot overcome the adhesion force on the other side, resulting in the bag opening not being able to open completely. Furthermore, the friction between the nitrile gloves and the bag wall is high, and adsorption on one side can easily cause the bag opening to tilt, preventing the gloves from accurately entering the bag and even tearing the packaging.

[0024] 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.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a nitrile glove packaging device, including a belt conveyor 1 and side support bars 2 fixed on the front and rear sides of the belt conveyor 1. Each side support bar 2 has two symmetrically arranged negative pressure holes 201 for adsorbing the bottom of the packaging bag 22. The bottom of the side support bar 2 is fixedly connected to a U-shaped conduit 3 that is connected to the negative pressure hole 201. A connecting pipe 4 is provided between the two U-shaped conduits 3. A negative pressure pneumatic component is provided below the belt conveyor 1. The negative pressure pneumatic component is connected to the connecting pipe 4. The negative pressure pneumatic component is also provided with a top adsorption component for adsorbing the top of the packaging bag 22.

[0026] The packaging bag 22 is conveyed to the packaging area by the belt conveyor 1 (that is, both ends of the packaging bag 22 are above the negative pressure holes 201 of the side support strip 2). At this time, the belt conveyor 1 stops and the negative pressure pneumatic component generates suction to draw the gas from the negative pressure hole 201 through the connecting pipe 4 and the U-shaped conduit 3. At this time, the negative pressure hole 201 generates negative pressure, which adsorbs both ends of the bottom of the packaging bag 22 to ensure the stability during packaging. The negative pressure pneumatic component also generates suction on the top adsorption component, that is, the top adsorption component adsorbs the top of the bag opening of the packaging bag 22 to open the bag opening.

[0027] See Figures 3 to 4 The negative pressure pneumatic assembly includes an air pump 5 and an air inlet end 6 fixed to the air inlet of the air pump 5. The upper end of the air inlet end 6 is connected to the connecting pipe 4.

[0028] See Figure 1 The top adsorption assembly includes a hose 7, one end of which is connected to the air inlet 6, and the other end of which is connected to a U-shaped suction pipe 8. The bottom of the U-shaped suction pipe 8 has two suction nozzles 9 for adsorbing the top of the packaging bag 22.

[0029] By starting the air pump 5, the gas is drawn into the negative pressure hole 201 through the connecting pipe 4 and the U-shaped conduit 3. The suction at the negative pressure hole 201 adsorbs the bottom of the packaging bag 22.

[0030] At the same time, the air pump 5 generates suction at the nozzle 9 through the hose 7 and the U-shaped suction pipe 8, that is, it adsorbs the top of the packaging bag 22 from above, and finally adsorbs the packaging bag 22 from both the top and bottom, so that the opening of the packaging bag 22 is fully opened, thereby ensuring that the nitrile gloves can be smoothly pushed into the packaging bag 22 through the opening, while preventing the packaging bag 22 from tilting or shifting during the packaging process; after the packaging is completed, the belt conveyor 1 is restarted.

[0031] See Figure 1 and Figure 2 A workbench 12 is provided on one side of the belt conveyor 1. The workbench 12 is aligned with one of the side support bars 2. A cylinder 10 is fixedly installed on the top of the workbench 12 by a bracket 11. The output end of the cylinder 10 is fixedly connected to the U-shaped suction pipe 8.

[0032] In addition, when adsorbing the top of the packaging bag 22, the cylinder 10 is used to drive the U-shaped suction pipe 8 and the suction nozzle 9 to move vertically downwards, so that the suction nozzle 9 contacts the top of the packaging bag 22. At this time, the suction nozzle 9 adsorbs, and then the cylinder 10 drives the suction nozzle 9 to move upwards, so that the bag opening is opened. After the glove is delivered into the packaging bag 22, the air pump 5 is turned off, the cylinder 10 drives the suction nozzle 9 to reset, and the belt conveyor 1 is restarted to drive the packaging bag 22 to move.

[0033] See Figure 1 and Figure 2 The workbench 12 is equipped with a power pushing component, which includes a cylinder 13 fixedly installed on the top of the workbench 12. A push block 15 is fixedly connected to the output end of the cylinder 13, and a push strip 14 for pushing nitrile gloves is fixedly connected to the other end of the push block 15.

[0034] Once the packaging bag 22 is in the packaging position, the nitrile glove is placed on one side of the push bar 14. Then, cylinder 2 13 is activated to push the push block 15 and the push bar 14 to move linearly. The push bar 14 pushes the nitrile glove into the packaging bag 22 to complete the packaging work. After completion, cylinder 2 13 drives the push block 15 and the push bar 14 to reset, and the belt conveyor 1 is restarted to transport the packaging bag 22 containing the nitrile glove and other packaging bags 22 without nitrile gloves to other locations.

[0035] As another implementation method, see Figure 5 and Figure 6 Two gear racks 16 are fixedly connected to the push bar 14. The gear racks 16 are provided with linearly and equally spaced drive teeth 161. Two sets of spreading assemblies are provided on the worktable 12. The spreading assembly includes a rotating shaft 17 rotatably mounted on the top of the worktable 12 via a bearing 18, and a gear 21 fixed to the upper end of the rotating shaft 17. The gear 21 intermittently meshes with the drive teeth 161. A connecting rod 20 is fixedly connected to the circumferential side wall of the rotating shaft 17, and a tensioning column 19 is fixedly connected to the other end of the connecting rod 20.

[0036] During the movement of cylinder 13 driving push bar 14, push bar 14 simultaneously drives gear frame 16 to move synchronously. Gear frame 16 drives gear 21 to rotate through drive gear 161. Gear 21 drives connecting rod 20 and tensioning column 19 to rotate through rotating shaft 17. The two tensioning columns 19 open the horizontal sides of the bag opening, which helps to ensure that the gloves can enter the packaging bag 22 more smoothly. It should be noted that when drive gear 161 is on gear frame 16, it will not continue to drive gear 21 and tensioning column 19 to rotate after it separates from gear frame 16. However, push bar 14 will continue to push nitrile gloves to continue to move into the packaging bag 22, that is, tensioning column 19 will not break the bag opening.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
