Description

Technical Field

[0001] The present invention relates to the field of medical device production, and particularly to a novel single-piece mask packing mechanism. Background Art

[0002] Currently, most mask packaging is done manually. During machine packaging, there may be problems such as entanglement during the supply of packaging bags or masks, resulting in inaccurate numbers of packing belts. More seriously, the machine may be damaged by the rolled-in masks. Therefore, some larger enterprises adopt semi-automatic bagging methods. Even so, a large number of workers are still required for intermittent operations, which cannot fundamentally speed up the packing speed. Based on this problem, we have developed a fully automatic novel single-piece mask packing mechanism. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and meet the actual needs by providing a novel single-piece mask packing mechanism.

[0004] To achieve the purpose of the present invention, the technical solution adopted is: a novel single-piece mask packing mechanism, including a machine tool support 1, a conveyor belt 4 arranged on the machine tool support 1. At one end of the conveyor belt in the transmission direction, there are arranged a packaging bag supply mechanism, a bag opening device, and a bagging mechanism. There is also a mask feeding station 2 arranged on one side of the starting point of the conveyor belt 4 in the transmission direction, and a material grabbing station 3 arranged on the machine tool support 1. The mask feeding station 2 is provided with a slide rail 201 perpendicular to the mask conveying track on the machine tool support 1. One or more groups of feeding grooves 202 are arranged on the slide rail 201. After the material supply of each group of feeding grooves 202 ends, the feeding groove 202 to be supplied can be moved to the mask feeding station 2 by a pneumatic cylinder. A rotary material grabbing device is arranged at the material grabbing station 3. The rotary material grabbing device grabs and rotates the material in the feeding groove 202 by 180 degrees and places the material into the feeding groove 401 on the conveyor belt 4. The conveyor belt 4 moves to transport the material to the bagging station for bagging.

[0005] The rotary material grabbing device is driven to rotate by a servo motor arranged above it.

[0006] The rotary material grabbing device includes a vertically arranged rotating shaft 301. The upper part of the rotating shaft 301 is driven to rotate by a rotating device. A connecting plate 302 is horizontally arranged below the rotating shaft 301. A group of mask suction devices are arranged directly above the feeding grooves 202 and the feeding grooves 401 on both sides of the connecting plate 302. The mask suction devices are driven to move up and down by pneumatic cylinders. The mask suction devices on both sides can grab and release simultaneously, and rotate 180° after completing one process to perform the next process simultaneously.

[0007] The mask suction device includes a mask suction block 5, an I-shaped connection block 6, and a tracheal access tube 7. The upper part of the mask suction block 5 is fixedly connected to the connecting plate 302 through the I-shaped connection block 6. The center of the I-shaped connection block 6 is provided with a through opening, and the tracheal access tube 7 passes through the opening of the I-shaped connection block and communicates with the mask suction block.

[0008] Two trapezoidal weight reduction grooves 501 are provided on both sides of the upper part of the mask suction block.

[0009] Anti-adhesion baffles 203 are provided on both sides of the inner wall of the feeding groove 202. The mask suction block extends into the feeding groove 202 to suck the packaging bag. When passing through the anti-adhesion baffles 203, since the packaging bag is soft, the two sides of the packaging bag are distorted, so that the possibly adhered packaging bag is separated from the grabbed packaging bag.

[0010] Elastic sheets 204 are provided on both sides above the anti-adhesion baffles 203. The lower roots of the two elastic sheets 204 are connected to the side wall of the feeding groove, and the upper parts extend towards the middle in an "eight" shape.

[0011] A timing lifting device 205 is provided at the bottom of the feeding groove. A through hole is provided on one side above the feeding groove 202, and an infrared detector is provided at the corresponding position of the through hole.

[0012] The beneficial effects of the present invention are as follows:

[0013] The device improves the material taking device, adopts the process of rotating and taking and placing materials on both sides at the same time, so that the time of one process is saved each time, and the bagging speed is accelerated.

[0014] The device improves the bag supply device. During the material taking process, the mask is twisted and bent, so that the mask to be extracted is better separated from the mask below, so as to achieve the effect of accurate feeding.

[0015] All processes of the device are fully automated, and one or two workers can fully control the entire production line, so that the production efficiency is greatly improved. Description of the Drawings

[0025] Refer to Figure 1-8 。

[0026] The present invention discloses a new single-piece mask packing mechanism, including a machine tool bracket 1, a conveyor belt 4 arranged on the machine tool bracket 1. At one end of the conveyor belt in the transmission direction, there are arranged a packaging bag feeding mechanism, a bag opening device and a bagging mechanism. It also includes a mask feeding station 2 arranged on one side of the starting point of the conveyor belt 4 in the transmission direction, and a material grabbing station 3 arranged on the machine tool bracket 1; the mask feeding station 2 is provided with a slide rail 201 perpendicular to the mask conveying track on the machine tool bracket 1, and a group or more of feeding troughs 202 are arranged on the slide rail 201. After the material supply of each group of feeding troughs 202 is completed, the feeding trough 202 to be fed can be moved to the mask feeding station 2 through an air cylinder; a rotary material grabbing device is arranged on the material grabbing station 3, and the rotary material grabbing device grabs and rotates the material in the feeding trough 202 by 180 degrees, and places the material into the feeding trough 401 on the conveyor belt 4, and the conveyor belt 4 moves to the bagging station for bagging. The packaging bag feeding mechanism, the bag opening device and the bagging mechanism arranged at one end of the conveyor belt in the transmission direction are all common mechanisms driven by an air pump, which are not the innovation points of this patent, so they will not be elaborated in this device.

[0027] The rotary material grabbing device is driven to rotate by a servo motor arranged above it.

[0028] The rotary material grabbing device includes a vertically arranged rotating shaft 301, and the upper part of the rotating shaft 301 is driven to rotate by a rotating device; a connecting plate 302 is horizontally arranged below the rotating shaft 301, and a group of mask suction devices are arranged directly above the feeding troughs 202 and the feeding trough 401 on both sides of the connecting plate 302. The mask suction devices are driven to move up and down by air cylinders; the mask suction devices on both sides can grab and release at the same time, and rotate 180° after completing one process to perform the next process at the same time.

[0029] The mask suction device includes a mask suction block 5, an I-shaped connecting block 6, and an air pipe access tube 7; the upper part of the mask suction block 5 is fixedly connected to the connecting plate 302 through the I-shaped connecting block 6. The center of the I-shaped connecting block 6 is provided with a through opening, and the air pipe access tube 7 passes through the opening of the I-shaped connecting block and communicates with the mask suction block.

[0030] Two trapezoidal weight reduction grooves 501 are provided on both sides of the upper part of the mask suction block.

[0031] Anti-adhesion baffles 203 are provided on both sides of the inner wall of the feeding groove 202. The mask suction block extends into the feeding groove 202 to suck the packaging bag. When passing through the anti-adhesion baffle 203, since the packaging bag is soft, the two sides of the packaging bag are twisted, so that the possibly adhered packaging bag is separated from the grabbed packaging bag.

[0032] Elastic pieces 204 are provided on both sides above the anti-adhesion baffle 203. The lower ends of the two elastic pieces 204 are connected to the side wall of the feeding groove, and the upper parts extend towards the middle in an "eight" shape.

[0033] A timing lifting device 205 is provided at the bottom of the feeding groove. A through hole is provided on one side above the feeding groove 202, and an infrared detector is provided at the corresponding position of the through hole. The infrared detector detects the number of masks in the feeding groove 202. When the masks are almost used up, the waiting feeding groove 202 is replaced through the slide rail 201.

[0034] Specific implementation:

[0035] First step: First, debug and test the machine tool. After the debugging is completed, load the packaging bag; fill several feeding grooves 202 for supplying the bags, and slide the first group of feeding grooves 202 to the corresponding working positions through the slide rail 201.

[0036] Second step: Turn on the switch. The pneumatic rod on one side of the feeding groove 202 of the mask drives the mask suction block 5 to move downward to suck the mask. During the suction process, under the action of the elastic piece 204 and the anti-adhesion baffle 203, the mask will not be adhered. When the mask suction block 5 sucks the mask to the initial position, the rotating shaft 301 drives the mask suction block 5 to rotate 180° under the action of the stepping motor 303.

[0037] Third step: The mask suction block 5 on one side of the conveyor belt 4 places the mask on the conveyor belt 4 under the action of the pneumatic rod. At the same time, the mask suction block 5 on one side of the feeding groove 202 of the mask repeats the previous action. When the stepping motor proceeds to the next process, the conveyor belt 4 moves forward by one process correspondingly. By adopting the process of simultaneously picking and placing materials on both sides by rotation, the time of one process can be saved each time, and the bagging speed is increased.

[0038] The above are only embodiments of the present invention, and do not thus limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or any direct or indirect application in related technical fields, shall similarly be included within the patent protection scope of the present invention.
