Description

Technical Field

[0001] This utility model relates to the field of mask production technology, and in particular to a nose wire conveying device for a mask machine. Background Technology

[0002] A face mask is a protective device used to cover the mouth and nose, widely used in medical, industrial, and daily life. It blocks droplets, dust, and microorganisms, protecting the health of the wearer and others. The nose wire is a key component of the mask, usually made of a plastic-coated iron core strip, which is flexible. Its function is to ensure that the bridge of the mask fits the curve of the face, reducing air leakage, ensuring protective effectiveness, and improving wearing comfort.

[0003] When the nose wire mounting device of patent number 202021065431.3 is working, the nose wire is drawn out from the unwinding reel, passes through the guide wheel, the wire straightening wheel and the limiting through hole in sequence, and is then pressed and pulled out by the nose wire feeding drive wheel and driven wheel. After the nose wire enters the conveying groove, the nose wire cutting drive assembly drives the upper cutter to move downward through the rocker arm, which cooperates with the lower cutter to cut the nose wire. At the same time, the crank mechanism drives the push plate to push out the cut nose wire.

[0004] The aforementioned nose wire installation device suffers from an efficiency bottleneck: because the push plate must wait for the cutter to complete the cutting before it can push out the nose wire, and the unwinding reel must wait for the push plate to reset before it can continue feeding, there is a long waiting time in the work cycle. During this process, the push plate needs to wait for the nose wire to be unwound and cut sequentially before it can work, which restricts the production efficiency of masks. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a nose wire conveying device for a mask machine, which can improve the production efficiency of masks.

[0006] To solve the above-mentioned technical problems, the present invention provides a nose wire conveying device for a mask machine, comprising:

[0007] The feeding seat is equipped with a feeding trough for receiving nose wires and with its opening facing upwards;

[0008] The pusher seat is provided with a pusher slot, a pusher component for pushing the nose wire in the pusher slot backward out of the pusher seat, and a receiving slot connected to the pusher slot. The receiving slot is provided with its opening facing upward and is used to guide the nose wire into the pusher slot.

[0009] Two sets of pick-up and drop-down mechanisms are respectively set above the feeding trough and the receiving trough and are used to pick up or drop the nose wire;

[0010] And a rotating mechanism, used to drive the two sets of pick-and-place mechanisms to rotate back and forth 180 degrees.

[0011] As an improvement to the above solution, the pick-and-place mechanism includes a pick-and-place frame and two suction trays spaced apart on the left and right.

[0012] As an improvement to the above solution, the nose wire conveying device of the mask machine of this utility model also includes a lifting mechanism installed at the output end of the rotating mechanism. The output end of the lifting mechanism is provided with a connecting frame, and the picking and placing frames of the two sets of picking and placing mechanisms are all installed on the connecting frame.

[0013] As an improvement to the above solution, the feeding trough and receiving trough are provided with clearance notches for the suction plate to extend into.

[0014] As an improvement to the above solution, the lower end of the receiving trough is lower than the lower end of the feeding trough, and the height difference between the lower end of the receiving trough and the lower end of the feeding trough is 1-2 times the thickness of the nose wire.

[0015] As an improvement to the above solution, the pusher includes an upper pressing block and a lower pressing block fixed on the lower side of the upper pressing block, the receiving groove is disposed on the upper side of the upper pressing block, and the pusher groove is disposed on the lower side of the upper pressing block.

[0016] As an improvement to the above solution, the pushing component includes a sliding plate that is slidably connected to the pushing groove and the pressing block, and a driving component installed in front of the pressing block for driving the sliding plate to move back and forth.

[0017] As an improvement to the above solution, the driving component includes a drive motor, a crank mounted on the output end of the drive motor, and connecting rods with their two ends respectively hinged to the crank and the front end of the pressure block.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.

[0031] like Figures 1 to 4 As shown in the figure, a nose wire conveying device for a mask machine in this embodiment of the present invention includes a feeding seat 100, a pushing seat 200, two sets of picking and placing mechanisms 300 and a rotating mechanism 400.

[0032] The feeding seat 100 is provided with a feeding groove 110 for accommodating nose wires and having an upward-facing opening. In fact, the nose wire is elongated, and the feeding groove 110 matches the contour of the nose wire. In order to replenish the nose wires into the feeding groove 110 in a timely manner, a nose wire unwinding mechanism and a nose wire cutting mechanism, as described in the nose wire mounting device of patent number 202021065431.3 in the background art, can be used to cooperate with the feeding groove 110 to transport the nose wires into the feeding groove 110 and cut them one by one, thus providing a basis for transferring the nose wires into the pusher seat 200.

[0033] The pusher seat 200 and the feeder seat 100 are spaced apart and are provided with a pusher groove 210, a pusher component 220 for pushing the nose wire out of the pusher seat 200 backward from the pusher groove 210, and a receiving groove 230 communicating with the pusher groove 210. The receiving groove 230 is arranged with its opening facing upward and is used to guide the nose wire into the pusher groove 210. In fact, the pusher groove 210 runs through the front and rear sides of the pusher seat 200. The receiving groove 230 matches the contour of the nose wire and its lower end communicates with the pusher groove 210. The pusher component 220 can be a translational component whose output end extends into the pusher groove 210 and can move back and forth within the pusher groove 210, thereby driving the nose wire in the pusher groove 210 to move backward away from the pusher seat 200.

[0034] The two sets of pick-and-place mechanisms 300 are respectively arranged above the feeding trough 110 and the receiving trough 230 and are used to pick up or put down the nose wire. In fact, the pick-and-place mechanism 300 can be a vacuum suction cup or an electromagnetic adsorption head (for nose wires made of metal that can be attracted by an electromagnet), which can pick up the nose wire in the feeding trough 110 and put it into the receiving trough 230.

[0035] The rotating mechanism 400 drives two sets of pick-and-place mechanisms 300 to rotate back and forth by 180 degrees. In practice, the rotating mechanism 400 can be a rotary motor or a rotary cylinder, capable of driving the two sets to rotate back and forth by 180 degrees. In actual application, the two sets of pick-and-place mechanisms 300 are evenly distributed around the rotation axis of the output end of the rotating mechanism 400. Initially, one set of pick-and-place mechanisms 300 is located above the feeding trough 110, and the other set is located above the receiving trough 230. After the rotating mechanism 400 drives the two sets of pick-and-place mechanisms 300 to rotate synchronously by 180 degrees, the positions of the two sets of pick-and-place mechanisms 300 are interchanged, providing conditions for the nose wire to move from the feeding trough 110 to the receiving trough 230. It should be noted that the feeding trough 110 and the pushing trough 210 of this invention extend to the left and right, ensuring that the nose wire in the feeding trough 110 can still be placed into the receiving trough 230 after a 180-degree rotation without affecting subsequent mask processing.

[0036] The following explains the specific working principle of the nose wire conveying device of this utility model, using the nose wire unwinding mechanism and nose wire cutting mechanism in conjunction with the external matching mechanism: The external nose wire unwinding mechanism outputs the nose wire into the feeding trough 110 of the feeding seat 100. When the length of the nose wire in the feeding trough 110 reaches the set length, the external nose wire cutting mechanism cuts the nose wire. The pick-and-place mechanism 300 located above the feeding trough 110 actuates to pick up the nose wire. At this time, the external nose wire unwinding mechanism and nose wire cutting mechanism can continue to convey and cut the nose wire into the feeding trough 110. The rotating mechanism 400 drives the two sets of pick-and-place mechanisms 300 to rotate 180 degrees, and the positions of the two pick-and-place mechanisms 300 are interchanged. The pick-and-place mechanism 300 with the nose wire adsorbed is located above the receiving trough 230, and the pick-and-place mechanism 300 without the nose wire adsorbed is located above the feeding trough and can pick up the nose wire. The nose wire is placed in the feeding trough 110; the nose wire pick-and-place mechanism 300, which adsorbs the nose wire, puts the nose wire down, and the put-down nose wire falls into the receiving trough 230 and then into the pushing trough 210. At this time, the rotating mechanism 400 drives the two sets of pick-and-place mechanisms 300 to rotate 180 degrees and exchange positions, so that the nose wire pick-and-place mechanism 300 is moved back to the receiving trough 230 to prepare for the next nose wire to be put into the receiving trough 230; after the pushing component 220 pushes the nose wire out of the pushing trough 210 and pushes it to the subsequent mask processing process and resets, the nose wire pick-and-place mechanism 300 can immediately put the nose wire into the receiving trough 230. The pushing component 220 does not need to wait for the external nose wire unwinding mechanism and nose wire cutting mechanism to complete the nose wire output and cutting before entering the next working cycle, reducing the waiting time of the pushing component 220 and improving the production efficiency of the mask.

[0037] The nose wire conveying device of this utility model for mask making machines, through the cooperation of the feeding seat 100, the pushing seat 200, two sets of picking and placing mechanisms 300 and the rotating mechanism 400, can make the pushing component 220 work independently of the unwinding and cutting of the external nose wire. That is, after the pushing component 220 is reset, the cut nose wire can be added into the pushing groove 210 more quickly, reducing the waiting time of the pushing component 220 and improving the production efficiency of masks.

[0038] Specifically, the pick-and-place mechanism 300 preferably includes a pick-and-place frame 310 and two suction cups 320 spaced apart on the left and right. In practice, the suction cups 320 are in contact with an external vacuum generator or compressed air via air tubes. When the nose wire needs to be lifted, a negative pressure is generated at the lower output end of the suction cup 320 to lift the nose wire; when the nose wire needs to be lowered, a positive pressure is generated at the lower output end of the suction cup 320 to lower the nose wire, thus achieving the lifting or lowering of the nose wire. It should be noted that the distance between the lower output end of the suction cup 320 and the upper side of the nose wire inside the feeding trough 110 should be within the suction range of the suction cup 320 to ensure that the nose wire can be lifted.

[0039] More specifically, the nose wire conveying device of this utility model preferably includes a lifting mechanism 500 installed at the output end of the rotating mechanism 400. The output end of the lifting mechanism 500 is provided with a connecting frame 510, and the picking and placing frames 310 of the two sets of picking and placing mechanisms 300 are both installed on the connecting frame 510. In fact, the lifting mechanism 500 can be a cylinder, hydraulic cylinder, electric telescopic rod, etc., which can drive the two sets of picking and placing mechanisms 300 installed on the picking and placing frame 310 to move up and down to change their positions. When it is necessary to absorb or put down the nose wire, the lifting mechanism 500 drives the two sets of picking and placing mechanisms 300 to move down to the lower position to ensure smooth absorption or placement of the nose wire; when it is necessary to rotate the two sets of picking and placing mechanisms 300, the lifting mechanism 500 drives the two sets of picking and placing mechanisms 300 to move up to the upper position to prevent interference with the feeding seat 100 or the pushing seat 200 during rotation.

[0040] Furthermore, the feeding trough 110 and the receiving trough 230 are preferably provided with clearance notches 120 for the suction plate 320 to extend into, so that the lower part of the suction plate 320 can enter the feeding trough 110 or the receiving trough 230, making it easier for the suction plate 320 to pick up the nose wire or for the lowered nose wire to smoothly enter the pushing trough 210 under the restriction of the receiving trough 230.

[0041] Furthermore, the lower end of the receiving groove 230 is preferably lower than the lower end of the feeding groove 110, and the height difference between the lower end of the receiving groove 230 and the lower end of the feeding groove 110 is 1-2 times the thickness of the nose wire. This avoids collision between the nose wire and the bottom of the receiving groove 230 when the nose wire is lowered, and provides sufficient distance for the nose wire to fall into the pushing groove 210, reducing the probability of nose wire deformation and improving the smoothness of subsequent mask processing.

[0042] It should be noted that the pusher seat 200 preferably includes an upper pressing block 240 and a lower pressing block 250 fixed to the lower side of the upper pressing block 240. The receiving groove 230 is disposed on the upper side of the upper pressing block 240, and the push groove 210 is disposed on the lower side of the upper pressing block 240. In practice, the receiving groove 230 and the push groove 210 can be machined on the upper pressing block 240 first, and then the upper pressing block 240 can be fixed on the lower pressing block 250. This avoids the influence between the receiving groove 230 and the push groove 210 during subsequent assembly, and ensures that the nose wire can be smoothly transferred from the receiving groove 230 to the push groove 210.

[0043] Specifically, the pushing component 220 preferably includes a sliding plate 221 slidably connected to the pushing groove 210 and the pressing block 250, and a driving component 222 installed in front of the pressing block 250 for driving the sliding plate 221 to move back and forth. In practice, the driving component 222 can be a cylinder or a single-axis translation lamp, capable of driving the sliding plate 221 to move back and forth along the pushing groove 210. When the driving component 222 is working, the sliding plate 221 moves forward and pushes the nose wire in the pushing groove 210 backward out of the pushing seat 200, allowing the nose wire to enter the subsequent mask processing steps.

[0044] More specifically, the driving component 222 preferably includes a drive motor 223, a crank 224 mounted on the output end of the drive motor 223, and a connecting rod 225 hinged at both ends to the crank 224 and the front end of the pressure block, respectively. In practice, when the drive motor 223 is started, the crank 224 rotates and drives the pressure block to move back and forth through the connecting rod 225, thereby pushing the slide plate 221 to slide along the direction of the push groove 210 to push the nose wire.

[0045] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
