After defoaming, the rotating assembly resets, allowing the packaging box to be removed as a whole, preventing bubble generation during unloading from the holding chamber.

Description

Technical Field

[0001] This invention relates to a bubble collection device, and more particularly to a bubble collection device and its control method for a raw material box used in PVC glove production, belonging to the technical field of PVC glove processing equipment. Background Technology

[0002] During the manufacturing process of PVC gloves, various raw materials need to be proportioned and mixed evenly to form a viscous paste. Air bubbles may appear during mixing, which can cause defects on the surface of the gloves and lead to product defects. Therefore, it is necessary to perform a de-bubbling operation.

[0003] Existing degassing equipment typically uses vacuum centrifugation to separate bubbles. However, during the production process, after the raw materials are prepared, they are usually transported to the production line in large packaging boxes or barrels for glove production. Conventional vacuum centrifugation requires pouring the raw materials into the equipment's holding chamber, which requires additional back-and-forth handling. During this handling process, bubbles are easily generated, and during centrifugation, gel-like substances may splash out of the holding chamber. Summary of the Invention

[0004] The main purpose of this invention is to solve the problem of existing raw material handling that requires additional back-and-forth transport, which results in air bubbles and splashing during the debugging process. The invention provides an air bubble collection device for PVC glove production raw material boxes.

[0005] The objective of this invention can be achieved by adopting the following technical solution:

[0006] A bubble collection device for PVC glove production raw material boxes includes a barrel body and a barrel cover disposed on the upper end of the barrel body. A rotating assembly is installed inside the barrel body. A turntable is rotatably connected to the bottom inner side of the barrel body. A positioning ring is disposed at the center of the turntable. A vacuum pump is disposed at the upper end of the barrel cover. A connecting sleeve is disposed at the lower end of the barrel cover. A movable connecting rod is disposed below the connecting sleeve. A movable ring plate is rotatably connected to the lower part of the movable connecting rod. An upper limit plate and a lower limit plate are disposed above and below the movable ring plate, respectively. A stirring shaft is disposed below the lower limit plate. A heating tube is disposed inside the stirring shaft.

[0007] Furthermore, a first spring is provided between the movable connecting rod and the connecting sleeve, and the movable connecting rod is slidably connected to the inner wall of the connecting sleeve.

[0008] Furthermore, a rubber sheet is provided at the bottom of the movable ring plate.

[0009] Furthermore, a connecting block is provided in the middle of the stirring shaft, and a through hole is provided in the middle of the connecting block for the heating tube to pass through.

[0010] Furthermore, the rotating assembly includes a fixed plate fixed to the inner wall of the barrel. Two sets of driving components are symmetrically installed on the upper part of the fixed plate. Each driving component includes two first electric telescopic rods that are mounted at an angle to the fixed plate. A movable frame is provided between the two first electric telescopic rods. Rubber wheels are installed on the ends of the two first electric telescopic rods and the movable frame that are close to each other. A drive motor for driving the rubber wheel is provided above one of the rubber wheels. A belt is sleeved on the rubber wheel. A second electric telescopic rod is provided below each of the two first electric telescopic rods.

[0011] Furthermore, the bottom end of the fixing plate is 10cm-20cm away from the inner bottom of the barrel.

[0012] Furthermore, a second spring is fitted onto the outer wall of the movable frame.

[0013] Furthermore, the output end of the second electric telescopic rod is equipped with a rubber wheel.

[0014] A method for controlling an air bubble collection device used in a raw material box for PVC glove production includes the following steps:

[0015] Step 1: Put the prepared glove raw materials and their packaging barrel into the barrel body and position them accurately by positioning ring. Then, extend the rubber wheel and stick it to the outer wall of the packaging barrel by rotating the first and second electric telescopic rods in the assembly.

[0016] Step 2: Assemble the lid onto the barrel body from top to bottom, so that the heating tube and stirring shaft are inserted into the packaging barrel, while the movable ring plate presses down on the top opening of the packaging barrel;

[0017] Step 3: The drive motor in the rotating assembly drives the rubber wheel to rotate, causing the packaging barrel to rotate on the turntable. At the same time, the temperature is increased by the heating tube. The probe of the vacuum pump is installed on the lower limit plate. The vacuum pump, together with the stirring shaft, is used to remove bubbles.

[0018] Furthermore, the movable ring plate can be tightly fitted to the top of the packaging barrel via the rubber sheet, facilitating vacuum degassing by the vacuum pump.

[0019] The beneficial technical effects of the present invention are as follows: According to the bubble collection device and control method for PVC glove production raw material boxes of the present invention, a cylindrical packaging barrel or cylindrical packaging box containing raw materials is placed in the middle of the rotating component inside the barrel. Then, the packaging barrel is limited by the first electric telescopic rod in conjunction with the belt on the rubber wheel. The barrel lid is closed, and the movable ring plate is pressed against the upper opening of the packaging barrel to prevent splashing when the packaging barrel rotates. The rotating component drives the packaging barrel to rotate on the turntable, and the stirring shaft below the lower limit plate is used for stirring. The use of a heating tube can improve the defoaming efficiency. At the same time, the vacuum pump effectively removes bubbles. After the defoaming is completed, the rotating component is reset, so that the packaging box can be taken out as a whole, avoiding the generation of bubbles when it is transported out of the holding chamber.
