Description

Technical Field

[0001] This utility model relates to the field of PVC glove dust removal, specifically to a PVC glove production dust removal device. Background Technology

[0002] PVC gloves are processed using either powdered or powderless methods. The powdered processing includes steps such as "powdering - demolding - powder removal". The powder removal process corresponds to the powdering step and removes excess powder adhering to the outside of the gloves.

[0003] PVC glove powder removal typically employs exhaust-type equipment. Airflow carries the powder off the gloves to remove excess powder. The degree of powder removal depends on the exhaust volume, usually requiring a very strong airflow. Once the dust solidifies, the required airflow becomes even stronger. Some technicians have considered using a brush to directly scrub the gloves to remove the powder. However, PVC gloves are thin, and direct contact for powder removal carries a significant risk of tearing the gloves. Therefore, this paper proposes a PVC glove production powder removal device. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is that in the process of removing dust from PVC gloves, the traditional ventilation method has the disadvantage of poor dust removal effect due to insufficient airflow, while directly using tools such as brushes to wipe the gloves to remove dust has a high probability of tearing the gloves.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Example 1

[0028] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a dust removal device for PVC glove production, combined with the attached... Figure 1-2 It includes a powder removal box 1, with openings 2 at both ends of the top of the powder removal box 1 to allow a transport mechanism to carry PVC gloves through the box. Multiple observation windows 22 are installed on the top of the powder removal box 1 via a sealing assembly to facilitate external monitoring of its internal operation. (Continuing with the attached...) Figure 3-5 The powder removal box 1 is provided with nozzles 15 arranged on both sides opposite each other, which blow away the excess powder adhering to the PVC gloves by spraying out a strong airflow;

[0029] The PVC glove transport mechanism is an existing technology equipment in the PVC glove de-dust treatment process. It mainly uses a conveyor chain 6 or conveyor belt to load or carry PVC gloves through the de-dust box 1 for de-dust treatment. The technical solution of this application is different from the method of removing excess powder residue on PVC gloves by exhaust. It mainly uses a powerful blowing method for de-dust treatment. With the assistance of the axial flow fan 19 that collects waste powder, which also has an exhaust effect, more efficient PVC glove de-dust treatment is achieved.

[0030] The powder removal box 1 is connected to an air supply system that supplies airflow to the nozzles 15 to blow off excess powder from the PVC gloves. The air supply system includes an air supply network 9, which is installed inside the powder removal box 1. An air pump 10 is installed at the end of the air supply network 9 to enhance the air pressure of the airflow ejected from the nozzles 15. The bottom end of the air supply pipe 11 is inserted into the air supply network 9 and is rotatably connected to it through a sealed bearing.

[0031] The front end of the air supply system is installed on the prepared air compressor, clean air storage tank and other equipment and facilities as the air delivery path to provide a strong airflow to the nozzle 15. An air pump 10 can be added to the air supply network 9, which serves as the main pipeline, to increase the jet force. Since the nozzle 15 in this device has the function of position movement, in order to achieve these effects, a rotatable air delivery pipe 11 and a telescopic flexible hose 16 that can not restrict the position of the pipe are installed at the end of the air supply system through a sealed bearing.

[0032] The bottom of the powder removal box 1 is equipped with multiple axial flow fans 19 to absorb excess powder from PVC gloves. The powder removal box 1 is located below the axial flow fans 19 and has a dust chamber 20 that can temporarily store excess powder that falls off the PVC gloves. The powder removal box 1 and the axial flow fans 19 are connected by a steep slope surface 18 that facilitates the collection of powder into the air duct of the axial flow fans 19. The bottom side of the powder removal box 1 is connected to a discharge port 21 that connects the dust chamber 20 and the powder recovery equipment.

[0033] In addition to removing PVC gloves by exhausting air, as is the case with other current powder removal equipment, the axial flow fan 19 in this device mainly captures, absorbs, and gathers the powder that floats in the powder removal box 1 after being blown away by the nozzle 15. It then quickly recovers the powder into the well-sealed dust hopper 20 below. This serves two purposes: first, it protects the environment in the powder removal box 1; second, it prevents the powder, mainly cornstarch, from spreading in the air and causing a dust explosion. For safety reasons, the dust hopper 20 is connected to relevant powder recovery and processing equipment through the discharge port 21, ensuring safety. The powder recovery and processing equipment is part of the existing technology and will not be described in detail here.

[0034] Example 2

[0035] The powder removal box 1 is equipped with a horizontal oscillating assembly that drives the nozzle 15 to rotate left and right. The horizontal oscillating assembly includes an air supply pipe 11. Support plates 12 are connected to the inner walls of both sides of the powder removal box 1. The air supply pipe 11 is rotatably connected to the support plates 12. The nozzle 15 is connected to the top of the air supply pipe 11. A gear 13 is installed on the outside of the air supply pipe 11. Multiple supports with multiple screw sleeves at the bottom are connected inside the powder removal box 1. A rack 8 is connected to one side of each support. The support is connected to the rack 8. The gears 13 mesh with each other and drive the air supply pipe 11 to rotate in the moving state. The powder removal box 1 is connected to a power mechanism for driving the support to move. The power mechanism includes a screw 3 that cooperates with the support through a threaded structure. The screw 3 is rotatably connected to the support inside the powder removal box 1. A sprocket 5 is connected to the end of the screw 3. A chain 6 is connected between the sprockets 5 and can make the two screws 3 rotate synchronously by cooperating with the sprockets 5. A motor 4 that cooperates with the screw 3 is installed on one side of the powder removal box 1.

[0036] The power output shaft of motor 4 is installed at the end of one of the screws 3 through components and methods such as couplings. After motor 4 is running, this screw 3 rotates and, through the transmission action of the sprocket 5 and chain 6 at its end, the two screws 3 rotate synchronously in the demolding box. The support above it is connected to it through a threaded structure. Under its rotation, the support will move along the axial direction of the screw 3. On one side of the support, many guide teeth are evenly arranged to form a rack 8. The rack 8 meshes with the gear 13 on the air supply pipe 11 of the nozzle 15, thereby driving the air supply pipe 11 and the nozzle 15 to rotate left and right in the horizontal position, thus expanding the range of air jet from the nozzle 15.

[0037] The powder removal box 1 is also equipped with a vertical swing assembly that drives the nozzle 15 to rotate up and down. The vertical swing assembly includes an electric telescopic rod 17. The nozzle 15 and the air supply pipe 11 are connected together by an elbow 14. The nozzle 15 and the elbow 14 are connected together by a telescopic hose 16. The electric telescopic rod 17 is rotatably connected between the nozzle 15 and the air supply pipe 11.

[0038] After the nozzle 15 is installed on the air supply pipe 11 via the elbow 14, it is arranged horizontally. A telescopic hose 16 is installed between the nozzle 15 and the elbow 14, which allows the arrangement of the nozzle 15 to be less restricted. When the electric telescopic rod 17 between the nozzle 15 and the air supply pipe 11 is extended or shortened, the nozzle 15 will also tilt upward or downward accordingly, thereby achieving vertical rotation based on the vertical position, which further expands the range of the nozzle 15's air jet.

[0039] In a specific implementation of this invention, during the de-powdering process in the production of PVC gloves, the PVC gloves are transported one by one into the de-powdering box 1 by the relevant transport equipment. The nozzles 15 in the de-powdering box 1 blow away excess powder from the gloves by spraying a strong airflow onto the PVC gloves suspended on the transport mechanism. During the air-blowing process, the nozzles 15 rotate in a planned manner in the up-down and left-right directions to expand the air-blowing coverage area, so that the powder in each area of ​​the gloves can be removed from the gloves as quickly and effectively as possible. The powder that leaves the gloves is collected and temporarily stored in the sealed dust chamber 20 below under the strong suction of the axial flow fan 19.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
