Technical Field

[0001] The invention discloses a negative pressure glove box-entering device, belonging to the technical field of automatic packaging. Background Art

[0002] In the production of gloves, gloves need to be packed into boxes and then transported to the site of use. During the transportation process, especially in export container transportation, the volume of the goods directly affects the transportation cost, and the volume of the packaging box is certain. Therefore, in order to reduce the transportation cost, more and more gloves are required to be packed into the packaging box, but the existing equipment cannot meet this demand. If the gloves are blindly compressed and packed into the box, the gloves will be damaged during the compression process. When customers put forward strict packaging requirements, the packaging effect after being packed into the box is often not up to standard due to the large volume and scratches on the box.

The glove boxing mechanism 3 is arranged at the output end of the glove conveying mechanism 1. A glove pressing mechanism is also arranged on the upper side of the glove conveying mechanism 1. The vacuuming mechanism 2 is arranged on the glove conveying mechanism 1. The vacuuming mechanism 2 simultaneously vacuums a group of gloves on the glove conveying mechanism 1 and the surroundings of the corresponding glove pressing mechanism. Before the gloves are put into the box, the gloves and the surroundings of the glove pressing mechanism are vacuumed. The process of compressing the gloves by the glove pressing mechanism can timely discharge the air in the gloves, which can greatly compress the volume of the gloves, so that more gloves can be put into the packaging box. Compared with the previous packaging method, the same number of gloves can use fewer packaging boxes, thereby reducing the volume of the container occupied by the glove transportation and reducing the transportation cost of the packaging boxes. The negative pressure glove boxing device is suitable for the front section of glove boxing. It can be used alone or added to the boxing machine to complete the compression boxing work.

[0024] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments.

In order to improve the degree of automation, gloves are often placed on the upper side of the input end of the conveyor belt 5 by a robot. After the gloves are compressed, they are transferred to the glove boxing mechanism 3 by the robot. In order to facilitate the robot to take and place gloves, a robot clearance hole 6 is opened on the conveyor belt 5. A plurality of vertically arranged partitions 7 are arranged on the conveyor belt 5. A group of gloves is placed between two adjacent partitions 7. A robot clearance groove 8 is opened on the partition 7.

[0026] Reference Figures 5 and 6 The vacuum pumping mechanism 2 includes a vacuum box 9 and a vacuum pump. The vacuum box 9 is lifted and lowered by a first lifting mechanism and is arranged on the upper side of the conveyor belt 5. The vacuum box 9 is connected to the vacuum pump through a pipeline.

[0029] In the specific working process, the conveyor belt 5 drives the gloves to move toward the glove boxing mechanism 3. Before reaching the glove boxing mechanism 3, every two groups of gloves arrive directly below the two vacuum boxes 9. The conveyor belt 5 stops, and the first cylinder 10 drives the vacuum box 9 to press down on the conveyor belt 5. The two groups of gloves are respectively covered by the two vacuum boxes 9. The vacuum pump evacuates the vacuum boxes 9. At the same time, the second cylinder 13 presses down and drives the glove pressing plate 15 to press the gloves downward to discharge the air in the gloves. After the vacuum is formed in the vacuum box 9, it is maintained for 5 to 15 seconds. After reaching the set time, the vacuum breaking valve connected to the vacuum box 9 opens to put air into the vacuum box 9, and the vacuum pump is turned off at the same time. Finally, the second cylinder 13 is retracted, and the vacuum box 9 rises, completing the vacuuming process of the gloves. The conveyor belt 5 continues to transport the gloves, and finally transports them to the glove boxing station, and then the robot grabs the gloves and transfers them to the glove boxing mechanism 3 for boxing.
