Description

Technical Field

[0001] The utility model relates to the technical field of nitrile rubber glove production, in particular to a rubber vulcanization device for nitrile rubber glove production. Background Art

[0002] Nitrile rubber is prepared by emulsion polymerization of butadiene and acrylonitrile. Its products have excellent oil resistance, high abrasion resistance and good heat resistance. Therefore, nitrile rubber is often used as a raw material for the production of rubber gloves.

[0003] When using nitrile rubber for glove production, it is necessary to vulcanize the nitrile rubber. A vulcanizer is a machine for vulcanizing various rubber and plastic products, which has functions such as timing mold clamping, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. The vulcanizer is divided into three forms: electric heating, steam heating and heat-conducting oil heating; after the vulcanizer vulcanizes the nitrile rubber, the nitrile rubber may stick to the pressing plate of the vulcanizer due to operations such as extrusion. And the nitrile rubber has too high a temperature due to heating, making it difficult for the operator to directly remove the nitrile rubber from the pressing plate in time, thus reducing the production efficiency of nitrile rubber vulcanization.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Referring to Figures 1 - 4 , a rubber vulcanization equipment for producing nitrile rubber gloves includes a base 1. A hydraulic cylinder 3 is provided above one end of the base 1. The hydraulic cylinder 3 is vertically installed on the base 1 through a fixed seat 2. A lifting seat 4 is installed at the top of the hydraulic cylinder 3. A first hot pressing plate 5 is installed at the top of the lifting seat 4. A top seat 8 is provided above the lifting seat 4. A second hot pressing plate 9 corresponding to the first hot pressing plate 5 is arranged at the bottom of the top seat 8. Support shafts 7 are arranged at the bottom corners of the top seat 8. The bottom of the support shafts 7 slidably penetrates through the corners of the lifting seat 4 and is fixed on the support seat 6, and the support seat 6 is installed on the fixed seat 2. During use, the nitrile rubber to be vulcanized is placed on the first hot pressing plate 5. Under the lifting action of the hydraulic cylinder 3, the first hot pressing plate 5 is pushed to the second hot pressing plate 9, so as to complete the vulcanization operation under the extrusion and heating of the two hot pressing plates;

[0026] A chassis 10 is provided at the other end of the top of the base 1, and a controller is provided in the chassis 10. The controller is connected to the hydraulic cylinder 3, the first hot pressing plate 5, and the second hot pressing plate 9 through wires. A display is also provided on the side of the chassis 10. The display is a touch display, and the display is connected to the controller through a wire. When vulcanization is carried out, the operator can control the vulcanization operation through the display, thereby completing the nitrile rubber vulcanization operation.

[0027] When the mold is opened after vulcanization is completed, Figure 2 and Figure 3 As shown, a first U-shaped seat 12 with an opening facing the top seat 8 is provided on the top of the chassis 10, and a linear motor 11 is provided below the first U-shaped seat 12 to drive the first U-shaped seat 12 to perform linear motion toward the top seat 8, and the linear motor 11 is fixed on the chassis 10, and the linear motor 11 is connected to the controller through a wire; a second U-shaped seat 13 with an opening facing the top seat 8 is provided in the first U-shaped seat 12, and a first shovel plate 14 is connected to the top of the second U-shaped seat 13. In actual use, the first shovel plate 14 corresponds to the bottom surface of the second hot pressing plate 9, and a second shovel plate 15 is provided parallel to the bottom of the first shovel plate 14. The second shovel plate 15 is fixed in the second U-shaped seat 13 by a lifting frame. The linear motor 11 will drive the first U-shaped seat 12 to approach the nitrile rubber, so that the shovel plates pass through the upper and lower surfaces of the nitrile rubber respectively;

[0028] When the shovel plate passes through the upper and lower surfaces of the nitrile rubber, the upper and lower ends of the second U-shaped seat 13 are rotatably connected to the inner wall of the first U-shaped seat 12 through the second rotating shaft 19 and the first rotating shaft 17 respectively. A torsion spring 18 is sleeved on the first rotating shaft 17 and the second rotating shaft 19. One end of the torsion spring 18 is fixed on the first U-shaped seat 12 and the other end is fixed on the corresponding first rotating shaft 17 and the second rotating shaft 19. The second rotating shaft 19 passes through the first U-shaped seat 12 and is connected to a first cam 20. A second cam 21 is correspondingly provided on one side of the first cam 20. A drive shaft 22 is coaxially mounted on the second cam 21. The bottom of the drive shaft 22 is rotatably mounted on the first U-shaped seat The first drive motor 23 is fixed to the first U-shaped seat 12 through a bracket 24. The first drive motor 23 is connected to the controller through a wire. The first drive motor 23 drives the second cam 21 to rotate, thereby moving the first cam 20, so that the scraping plate can be deflected to one side. When deflected, the torsion spring 18 will produce an elastic effect due to its twisting, so that the scraping plate will swing back and forth continuously, so as to increase the contact area between the scraping plate and the nitrile rubber in the process of moving toward the nitrile rubber, and then completely scrape the nitrile rubber off the hot pressing plate to ensure normal discharge of the nitrile rubber.

[0029] It should be noted that the lifting frame includes a screw rod 25, which is perpendicular to the first scraping plate 14, and the end of the screw rod 25 is rotatably connected to the inner wall of the second U-shaped seat 13. The bottom of the screw rod 25 passes through the second U-shaped seat 13 and is connected to a second drive motor 27. The second drive motor 27 is connected to the controller through a wire, and the second drive motor 27 is arranged in a motor box 26, and the motor box 26 is fixed on the second U-shaped seat 13. The second scraping plate 15 is threadedly connected to the screw rod 25 through a nut, and the top of the first rotating shaft 17 is rotatably installed on the bottom of the motor box 26. The spacing between the two scraping plates can be adjusted so that the spacing between the scraping plates corresponds to the thickness of the nitrile rubber, which is conducive to the scraping plates extending from the upper and lower sides of the nitrile rubber into between the nitrile rubber and the hot pressing plate and scraping the nitrile rubber off the hot pressing plate.

[0030] Specifically, after the vulcanization treatment of the nitrile rubber is completed, the second drive motor 27 will drive the screw 25 to rotate to adjust the distance between the two shovel plates to correspond to the distance between the two hot pressing plates, and then the linear motor 11 drives the shovel plates to approach the nitrile rubber. Because the first shovel plate 14 and the second shovel plate 15 are relatively close to each other, an inclined surface 16 is provided. The inclined surface 16 is away from the second U-shaped seat 13, which can facilitate the shovel plate to extend into the hot pressing plate and the nitrile rubber. In this process, the hydraulic cylinder 3 can control the lifting seat 4 to move downward slightly to ensure that the shovel plate is close to the second hot pressing plate. The material plate can be more easily inserted between the nitrile rubber and the hot pressing plate; as the scraping plate is inserted, the scraping plate will swing back and forth under the interaction of the two cams, and as the linear motor 11 drives the scraping plate to continue to move forward, the fan-shaped swing of the scraping plate will continuously allow the nitrile rubber and the hot pressing plate to be progressively separated, thereby avoiding the situation where the nitrile rubber is to be torn due to sudden complete separation. Finally, after the nitrile rubber is completely separated from the hot pressing plate, the linear motor 11 can be reversed to allow the scraping plate to separate from the nitrile rubber. At this time, the hydraulic cylinder 3 can be controlled to drive the lifting seat 4 to descend and then take the nitrile rubber.

[0031] It should be noted that when the scraping plate is pulled away from the nitrile rubber, the scraping plate can still be kept in a swinging operation. This can facilitate the separation between the nitrile rubber and the scraping plate, and prevent the nitrile rubber from being carried out of the hot pressing plate with the scraping plate, and then falling and pressing on other equipment or power wires, causing damage to the equipment.

[0032] Furthermore, a guide shaft 28 is provided parallel to the side of the screw rod 25, the end of the guide shaft 28 is fixed to the inner wall of the second U-shaped seat 13, and the guide shaft 28 slides through the second scraping plate 15, so that the second scraping plate 15 can be stably lifted up and down; wherein, the guide shaft 28 is arranged on the side of the screw rod 25 close to the second scraping plate 15, which can hinder the contact between the nitrile rubber and the screw rod 25.

[0033] It should be further noted that a plurality of ventilation holes arranged at intervals are formed on the side surface of the motor box 26 to ventilate and dissipate heat from the second driving motor 27, ensuring the normal temperature of the second driving motor 27 during use.

[0034] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
