Description

Technical Field

[0001] The present invention relates to the technical field of mask processing, and in particular to a packaging device for mask processing. Background Art

[0002] A mask is a sanitary product, usually made of multiple layers of material, used to cover the mouth and nose, and plays a protective and filtering role. The mask has a certain filtering effect on the air entering the lungs, and can block harmful gases, odors, droplets, viruses and other substances. Masks play a very important role when respiratory infectious diseases are prevalent and when working in dusty and other polluted environments. Masks often need to be packaged when leaving the factory to prevent the masks that have just left the factory from coming into contact with the outside air and causing pollution.

[0003] In the existing mask production lines, most of the packaged masks are transported to the packaging machine through a conveyor belt for packaging. Conventionally, workers put the mask bags into the packaging machine mouth for heat sealing. This packaging method has a better sealing effect, but the efficiency of manual packaging is low. When using a conveyor belt for transportation without human intervention, the masks on the conveyor belt are prone to deviation, resulting in deviations when the packaging machine performs heat sealing, which greatly reduces the production qualification rate of masks. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the efficiency of existing manual packaging is low. When a conveyor belt is used for transportation, without manual intervention, the masks on the conveyor belt are easily offset, resulting in deviations when the packaging machine performs heat sealing, which greatly reduces the production qualification rate of the masks. A packaging device for mask processing is proposed to solve the problem that the efficiency of existing manual packaging is low. When a conveyor belt is used for transportation, without manual intervention, the masks on the conveyor belt are easily offset, resulting in deviations when the packaging machine performs heat sealing

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1-Figure 8A packaging device for mask processing includes a conveyor belt 1 placed on the ground, the outer wall of the conveyor belt 1 is fixedly connected to a first support frame 2, the top of the first support frame 2 is fixedly connected to a first hydraulic cylinder 3, the first hydraulic cylinder 3 is connected to a pressing roller 4 through a degassing structure, the outer wall of the conveyor belt 1 is fixedly connected to a second support frame 5, the top of the second support frame 5 is fixedly connected to a second hydraulic cylinder 6, the second hydraulic cylinder 6 is connected to a packaging machine 7 through a positioning packaging structure, and auxiliary straightening devices 8 are arranged on both sides of the outer wall of the second support frame 5.

[0019] It should be noted that the conveyor belt 1, the first hydraulic cylinder 3, the second hydraulic cylinder 6, the pressure sensor 23 and the third hydraulic cylinder 24 are existing technologies. The specific model specifications need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated.

[0020] Furthermore, the degassing structure includes a symmetrically distributed slide groove 9, a slider 10, a U-shaped frame 11, a T-shaped block 12, a first spring 13, and a movable sleeve 14. The slide groove 9 is arranged on both sides of the inner wall of the first support frame 2, and the slider 10 is slidably connected to the inner wall of the slide groove 9.

[0021] Among them, the pressure roller 4 can be pushed up and down by the first hydraulic cylinder 3, and the pressure roller 4 will not rotate when moving due to the restriction of the slide groove 9 and the slider 10, thereby reducing the problem of insufficient degassing caused by the bending of the pressure roller 4.

[0022] Furthermore, the outer wall of the U-shaped frame 11 is fixedly connected to the slider 10 , the pressure roller 4 is rotatably connected to the inner wall of the U-shaped frame 11 , and the top end of the movable sleeve 14 is fixedly connected to the telescopic end of the first hydraulic cylinder 3 .

[0023] The U-shaped frame 11 is arranged with its opening facing downward, and the length of the pressing roller 4 is greater than the width of the conveyor belt 1 , so that masks at any position of the conveyor belt 1 can be squeezed by the pressing roller 4 .

[0024] Furthermore, the bottom end of the T-block 12 is fixedly connected to the top of the U-frame 11, one end of the first spring 13 is fixedly connected to the top of the T-block 12, the other end of the first spring 13 is fixedly connected to the top of the inner wall of the moving sleeve 14, and the T-block 12 is slidably connected to the inner wall of the moving sleeve 14.

[0025] Among them, a groove in the shape of an inverted convex letter is opened at the bottom end of the movable sleeve 14, and the first spring 13 is arranged in the groove. The T-block 12 is slidably connected with the inside of the groove, so that the T-block 12 will not easily fall out of the groove. It can also cooperate with the first spring 13 to provide a buffer space for the pressure roller 4 to avoid excessive squeezing of the mask, which may cause damage to the mask.

[0026] Furthermore, the positioning packaging structure includes a symmetrically distributed stabilizing rod 15, an L-shaped movable plate 16, a rectangular groove 17, a sliding hole 18, a second spring 19, a limiting protrusion 20, a movable block 21, an arc groove 22, and a pressure sensor 23. The stabilizing rod 15 is slidably connected to the second support frame 5, and the bottom end of the stabilizing rod 15 is fixedly connected to the top end of the L-shaped movable plate 16.

[0027] The top end of the stabilizing rod 15 penetrates the outer wall of the second supporting frame 5 , so that the L-shaped movable plate 16 will not shake or deviate when moving downward.

[0028] Furthermore, the rectangular groove 17 is arranged at the top end of the outer wall of the L-shaped movable plate 16, the sliding hole 18 is arranged on both sides of the inner wall of the rectangular groove 17, the second spring 19 is arranged in the sliding hole 18 and fixedly connected to the inner wall of the sliding hole 18, the limiting protrusion 20 is slidably connected to the inner wall of the sliding hole 18, and the other end of the second spring 19 is fixedly connected to one end of the outer wall of the limiting protrusion 20.

[0029] The other end of the outer wall of the limiting protrusion 20 is set as a round head, and the position of the limiting protrusion 20 is adapted to the position of the arc groove 22, so that when the moving block 21 moves to the highest point, the limiting protrusion 20 and the arc groove 22 limit each other.

[0030] Furthermore, the moving block 21 is slidably connected to the inner wall of the rectangular groove 17, the arc grooves 22 are arranged on both sides of the outer wall of the moving block 21, the pressure sensor 23 is fixedly connected to the top of the moving block 21, and the packaging machine 7 is fixedly connected to one side of the bottom end of the outer wall of the moving block 21.

[0031] The cross section of the rectangular groove 17 is in a convex shape, so that the moving block 21 can be blocked when it moves to the top of the rectangular groove 17 and drives the L-shaped moving plate 16 to move upward at the same time.

[0032] Furthermore, the auxiliary righting device 8 includes a third hydraulic cylinder 24 and a righting plate 25 which are symmetrically distributed. The third hydraulic cylinder 24 is fixedly connected to the outer wall of the second support frame 5 , and the righting plate 25 is fixedly connected to the telescopic end of the third hydraulic cylinder 24 .

[0033] The bottom end of the straightening plate 25 abuts against the top end of the conveyor belt 1, and the two third hydraulic cylinders 24 are controlled by a program. The two third hydraulic cylinders 24 can be pushed inward at the same time, so that the straightening plate 25 can contact the mask in the second support frame 5 without being pushed crooked. Working principle: When using the above device, first put the masks packed in the packaging bag on the conveyor belt 1, and the conveyor belt 1 moves from left to right. The packaging bag will first pass through the degassing structure. The degassing structure is achieved by starting the first hydraulic cylinder 3. The first hydraulic cylinder 3 pushes the movable sleeve 14 to move downward, and the movable sleeve 14 drives the T-block 12 to move downward. The T-block 12 drives the U-frame 11 to move downward, and the U-frame 11 drives the pressure roller 4 to squeeze the packaging bag on the conveyor belt 1 to discharge the air in the packaging bag, and then transport it to the next area through the conveyor belt 1.

[0034] Then, when the packaging bag reaches the position of the second support frame 5, the second hydraulic cylinder 6 is first started to push the L-shaped movable plate 16 downward until it is against the top of the conveyor 1, thereby simultaneously starting the third hydraulic cylinders 24 on both sides to push the straightening plate 25 inward at the same time, straightening the packaging bag on the conveyor belt 1, and then the second hydraulic cylinder 6 continues to push down, and is subjected to the resistance of the L-shaped movable plate 16. The moving block 21 squeezes the limiting protrusion 20 to make it enter the sliding hole 18, and the moving block 21 without restriction continues to move downward and pushes the packaging machine 7 to move downward to contact the packaging bag. After the packaging machine 7 seals the packaging bag, the second hydraulic cylinder 6 is moved up to bring the moving block 21 and the L-shaped movable plate 16 back to their original positions, thereby completing the packaging of the mask.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
