[0027] The inner surface of the inspection table 27 is provided with a limiting groove 28, a cylinder is fixedly installed inside the inspection table 27, an abutting rod 29 is fixedly installed on the output end of the cylinder, an air nozzle 30 is fixedly installed on the surface of the limiting groove 28, a clamping disk 31 is fixedly installed on the surface of the abutting rod 29, a motor is fixedly installed inside the clamping disk 31, a roller 32 is fixedly installed on the output end of the motor, a pressure sensor 33 is fixedly installed on one end surface of the clamping disk 31, and a convex rod 38 is fixedly installed in the middle of one end surface of the clamping disk 31. When the PVC gloves are clamped and fixed, After the opening extends into the gap between the clamping plate 31 and the inspection table 27, the cylinder inside the inspection table 27 is activated, causing the clamping plate 31 to continuously move closer to the inspection table 27 until the clamping plate 31 is close to the inspection table 27 and the PVC glove is clamped. Then, air is injected into the glove using the air nozzle 30, and the pressure value change is recorded by the pressure sensor 33. The pressure value is compared with the preset value to determine whether the glove is qualified. The grip of the glove is then released, and the glove is moved to the appropriate placement position based on the qualified result.

[0028] A holding rack 2 is fixedly mounted on the bottom surface of the main frame 1, and a pad 3 is fixedly mounted inside the main frame 1. The two holding racks 2 can store qualified and unqualified PVC gloves respectively;

[0029] A frame 5 is fixedly installed on the bottom surface of the placement rack 4, and a first motor is installed on the surface of the frame 5. The inner surface of the frame 5 is rotatably connected to the first screw rod 6. The output end of the first motor is fixedly connected to the first screw rod 6. The surface of the first screw rod 6 is sleeved and connected with a connecting rod 7. The inner side of the frame 5 is rotatably connected to a scissor lift 8. The scissor lift 8 and the connecting rod 7 are movably connected. A connecting plate 9 is fixedly installed on the top surface of the scissor lift 8. The top surface of the connecting plate 9 is fixedly connected to a spring 10. A placement plate 11 is fixedly installed on the top surface of the spring 10. During the inspection of the PVC gloves, after they are placed head to tail on the surface of the placement plate 11, the suction cup 21 is used to absorb and transport the top layer of PVC gloves. In order to avoid leakage and falling, the first motor will operate periodically to make the scissor lift 8 continuously lifted to ensure that when the number of gloves is small, the suction cup 21 can still be convenient for absorption and transportation. The provided spring can play a buffering role when the suction cup 21 is pressed down for absorption, and to a certain extent, prevent the gloves from being damaged during the downward pressure of the suction cup 21.

[0030] The surface of the crossbeam 12 is fixedly mounted with a first slide rail 13, and the surface of the crossbeam 12 is fixedly mounted with a limiting seat 14 near the two short sides. The surface of the limiting seat 14 is rotatably connected to the second screw rod 15, and the surface of one of the limiting seats 14 is fixedly mounted with a second motor, and the output end of the second motor is fixedly connected to the second screw rod 15. The surfaces of the first slide rail 13 and the second screw rod 15 are sleeved and connected with a connecting seat 16, and the surface of the connecting seat 16 is fixedly mounted with a second slide rail 17. The surface of the second slide rail 17 is sleeved and connected with a moving plate 18. A telescopic cylinder 19 is fixedly mounted on the surface of one short side of the connecting seat 16. The surface of the moving plate 18 is fixed A jacket 20 is installed, and a suction cup 21 is clamped on the surface of the jacket 20. When the placed gloves are transported to the inspection table 21 for inspection, the second motor can drive the second screw rod 15 to rotate, thereby moving the connecting seat 16 on the surface of the first slide rail 13 until the connecting seat 16 is close to the placement plate 11. Then, the telescopic cylinder 19 is activated to slowly move the moving plate 18 downward until the suction cup 21 is attached to the surface of the gloves. The gloves are then sucked by the negative pressure machine and brought to the inspection table 27. At the same time, another set of beams 12 components can transport the inspected gloves according to the inspection results.

[0031] A vertical plate is fixedly mounted on the side surface of the mounting frame 22, and a socket is fixedly mounted on the surface of the vertical plate. A driving motor 23 is fixedly mounted on the surface of one of the sockets, and a third screw rod 24 is fixedly mounted on the output end of the driving motor 23. A sliding rod 25 is rotatably connected to the surface of the other socket, and a movable seat 26 is sleeved and connected to the surface of the sliding rod 25. During the glove testing process, the two driving motors 23 will be started simultaneously, and the third screw rod 24 will drive the movable seat 26 to move toward each other. This allows the next glove to be tested while waiting for the air pressure value to change, thereby accelerating the glove testing rate.

[0032] A third motor is fixedly installed inside the clamping disk 31, and a screw 34 is fixedly installed at the output end of the third motor. A connecting ring is welded and fixed to the surface of the screw 34 near one end edge. A positioning sleeve 36 is sleeved and connected to the surface of the connecting ring. A movable sleeve 35 is sleeved and connected to the surface of the screw 34. The side surfaces of the movable sleeve 35 and the positioning sleeve 36 are symmetrically and movably connected with a folding rod 37. During the process of the glove being adsorbed and transported to the inspection table 27, its opening is in an open state. During the process of approaching the inspection table 27, the protruding rod 38 will first extend into the opening. At this time, the third motor is started, causing the screw 34 to start rotating. During the process, the movable sleeve 35 will also continue to approach the positioning sleeve 36, thereby causing the folding rod 37 to start to bend continuously, so that the glove opening is opened wider, and the roller is more easily attached to the surface of the clamping disk 31.

[0033] The top surface of the inner side of the assembly rack 39 is fixedly installed with an inclined plate 40, and the interior of the assembly rack 39 is located below the inclined plate 40 and is rotatably connected to a pressure roller 41, and the side surface of the pressure roller 41 is fixedly installed with a pulley 42. The interior of the assembly rack 39 is fixedly installed with a conveyor rack 44 near the bottom end, and the surface of the conveyor rack 44 is sleeved with a conveyor belt 45. The interior of the conveyor rack 44 is rotatably connected to a conveyor roller, one of which is fixedly installed with a linkage wheel. The linkage wheel and the pulley 42 are connected by a belt, and a transmission gear 43 is fixedly installed on the surface of the linkage wheel. When the inspected gloves are brought to the top of the assembly rack 39, the gloves will fall on the surface of the inclined plate 20 after the suction cup 21 stops sucking. When the gloves move down along the inclined plate 20, the pulley 42 will flatten the gloves and drag them downward. After they fall on the surface of the conveyor rack 44, they will be moved to the surface of the holding rack 2 under the action of the conveyor belt 45, and then they can be collected and transported in a unified manner.

[0034] The working principle of the present invention is as follows: during the inspection of PVC gloves, after the gloves are placed head to tail on the surface of the placement plate 11, the suction cup 21 is used to absorb and transport the top layer of PVC gloves. In order to prevent leakage and falling, the first motor will operate regularly to continuously lift the scissor lift 8 to ensure that even when the number of gloves is small, the suction cup 21 can still be conveniently sucked and transported. The spring provided can play a buffering role when the suction cup 21 is pressed down to absorb, to a certain extent, to prevent the gloves from being damaged during the process of the suction cup 21 being pressed down. When the position of the inspection table 21 is to be inspected, the second motor can drive the second screw rod 15 to rotate, so that the connecting seat 16 moves on the surface of the first slide rail 13 until the connecting seat 16 is close to the placement plate 11, and then the telescopic cylinder 19 is started to slowly move the moving plate 18 down until the suction cup 21 is attached to the surface of the glove, and then the negative pressure machine is used to adsorb the glove and then bring it to the position of the inspection table 27. At the same time, another set of crossbeam 12 components can transport the inspected gloves according to the inspection results. When clamping and fixing the PVC gloves, wait for its opening position to be extended. After the gloves are moved into the gap between the clamping plate 31 and the inspection table 27, the cylinder inside the inspection table 27 can be started to make the clamping plate 31 move closer to the inspection table 27 until the clamping plate 31 is close to the inspection table 27 and the PVC gloves are clamped. Then, the air nozzle 30 can be used to blow air into the gloves, and the pressure value change is recorded by the pressure sensor 33. The pressure value is compared with the preset value to determine whether the gloves are qualified. Then, the clamping of the gloves is released and the gloves are moved to the appropriate placement position according to the qualified result. During the glove testing process, the two driving motors 23 will simultaneously When the glove is started, the third screw rod 24 drives the movable seat 26 to move toward each other. Thus, while waiting for the air pressure value to change, the next glove can still be tested, thereby accelerating the glove testing rate. When the tested glove is brought to the top of the assembly rack 39, the suction cup 21 stops sucking and the glove falls on the surface of the inclined plate 20. When the glove moves down along the inclined plate 20, the pulley 42 will flatten the glove and drag it downward. After it falls on the surface of the conveying rack 44, it will be moved to the surface of the holding rack 2 by the action of the conveyor belt 45, and then it can be collected and transported.

[0035] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
