As shown in fig. 1 to 5, a mask bridge line cutting device 100 according to an embodiment of the present invention includes a base, a first mounting seat 201, a line pressing unit 2, and a cutting unit 3, the first mounting seat 201 being provided on the base. The wire pressing unit 2 includes a first wire pressing roller 202, a second wire pressing roller 203, and a first motor 204, and the first wire pressing roller 202 and the second wire pressing roller 203 are abutted against each other and are both provided in the first mounting base 201. The first motor 204 is connected to any one of the first line roller 202 and the second line roller 203. The cutter unit 3 is disposed downstream of the line pressing unit 2. The cutting unit 3 includes a first cutting roller 301, a second cutting roller 302, and a second motor 304, and the first cutting roller 301 and the second cutting roller 302 are each mounted to the first mount 201. The first cutting roller 301 is provided with a cutter 303, and a second motor 304 is connected to the first cutting roller 301.
According to the mask nose bridge line cutting device 100 of the embodiment of the present invention, by providing the first line pressing roller 202 and the second line pressing roller 203 to abut against each other, the first line pressing roller 202 and the second line pressing roller 203 are relatively rotated by the driving of the first motor 204, and the nose bridge line between the first line pressing roller 202 and the second line pressing roller 203 can be conveyed to between the first cutting roller 301 and the second cutting roller 302 in the downstream cutting unit 3. Under the driving of the second motor 304, the first cutting roller 301 rotates to drive the cutter 303 to rotate, so that the cutting of the nose bridge line between the first cutting roller 301 and the second cutting roller 302 is realized.
The first wire pressing roller 202 or the second wire pressing roller 203 is driven by the first motor 204, the first cutting roller 301 is driven by the second motor 304, and the rotating speed ratio of the first wire pressing roller 202 to the first cutting roller 301 can be adjusted optionally, so that nose bridge lines with various lengths can be cut, and the universality of the mask nose bridge line cutting device 100 is further improved. In addition, through setting up two motor drive, the rotation of first wire pressing roller 202 and the rotation of first cutting roller 301 do not influence each other, two motors are direct to be connected with first wire pressing roller 202 and the transmission of first cutting roller 301, the transmission structure between power supply and line ball unit 2 and the cutting unit 3 has been reduced, reduce transmission loss, and then first wire pressing roller 202 and first cutting roller 301 can reach higher rotational speed, make the production speed of nose bridge line faster from this, especially, satisfy the demand that high speed mask machine's high speed cut nose bridge line.

For the sake of easy understanding, arrow a in fig. 3 indicates the left-right direction of the mask nose bridge line cutting device 100, arrow B in fig. 3 indicates the up-down direction of the mask nose bridge line cutting device 100, and arrow C in fig. 4 indicates the front-back direction of the mask nose bridge line cutting device 100.
As shown in fig. 1 to 5, the mask bridge line cutting apparatus may include a base, a first mount 201, a second mount 101, a wire unit 1, a wire pressing unit 2, a cutting unit 3, and a guide frame 4. The second mounting seat 101 and the first mounting seat 201 are both arranged on the base and are arranged at intervals from left to right. For example, the second mount 101 may be located on the left side of the first mount 201. The wire unit 1 is mounted on the second mounting seat 101, the wire pressing unit 2 and the cutting unit 3 are both partially mounted on the first mounting seat 201, that is, a part of the wire pressing unit 2 is mounted on the first mounting seat 201, and a part of the cutting unit 3 is mounted on the first mounting seat 201. The guide frame 4 is mounted in front of the first mounting seat 201.
In some embodiments, the first mounting seat is disposed on the base, the wire unit includes a first wire guide wheel and a second wire guide wheel, the first wire guide wheel and the second wire guide wheel are both disposed on the first mounting seat, and the second wire guide wheel is movably disposed relatively close to and away from the first wire guide wheel so as to be close to and away from the first wire guide wheel.
By making the second wire guide wheel 103 movable relative to the first wire guide wheel 102, the distance between the first wire guide wheel 102 and the second wire guide wheel 103 can be made adjustable. Therefore, the first wire guide wheel 102 and the second wire guide wheel 103 can adapt to nose bridge lines with different materials or thicknesses (thicknesses), namely when the materials or the thicknesses (thicknesses) of the nose bridge lines are changed, the second wire guide wheel 103 can move relative to the first wire guide wheel 102, so that the first wire guide wheel 102 and the second wire guide wheel 103 can apply different pressing forces to the nose bridge lines with different materials or thicknesses (thicknesses), the first wire guide wheel 102 and the second wire guide wheel 103 can always provide set pressing forces to various nose bridge lines, the guiding effect to the nose bridge lines is guaranteed, and the universality is high.
It should be noted that, the nose bridge lines are made of different materials and have different deformation resistances, and the nose bridge line with the larger deformation resistance needs to be subjected to a larger external force to complete the plastic deformation. If the nose bridge line is cut to have a greater resistance to deformation, the first wire guide 102 is required to press the nose bridge line further toward the second wire guide 103 so that the pressing force of the first wire guide 102 and the second wire guide 103 against the nose bridge line is increased until plastic deformation of the nose bridge line can be achieved. Furthermore, the thickness (thickness) of the bridge line is different, and the distance between the first wire guide wheel 102 and the second wire guide wheel 103 also needs to be adjusted. When a nose bridge line with a larger thickness (thickness) is to be cut, the first wire guide wheel 102 needs to be far away from the second wire guide wheel 103, so that the distance between the first wire guide wheel 102 and the second wire guide wheel 103 can be ensured to be passed by the nose bridge line, and meanwhile, the first wire guide wheel 102 and the second wire guide wheel 103 also provide a set pressing force for the nose bridge line.
In some embodiments, the wire guiding unit 1 includes a plurality of first wire guiding wheels 102 and a plurality of second wire guiding wheels 103, the plurality of first wire guiding wheels 102 and the plurality of second wire guiding wheels 103 are alternately arranged in a first direction, and the plurality of second wire guiding wheels 103 are slidably arranged in the second mounting seat 101 along a second direction, the second direction being perpendicular to the first direction.
As shown in fig. 3, the first direction is a left-right direction, and the second direction is an up-down direction. Three first wire guide wheels 102 are provided, and the three first wire guide wheels 102 are mounted on the second mounting base 101 at intervals in the left-right direction. Two second wire guide wheels 103 are movably installed on the second installation base 101 at intervals in the left-right direction, and the two second wire guide wheels 103 are alternately arranged with the three first wire guide wheels 102. The moving direction of the two second guide rollers 103 is the up-down direction. The nose line sequentially passes through a first wire guide wheel 102 on the left side, a second wire guide wheel 103 on the left side, a first wire guide wheel 102 in the middle, a second wire guide wheel 103 on the right side and a first wire guide wheel 102 on the right side from left to right. The two second guide wheels 103 move downwards to be close to the corresponding first guide wheels 102, so that the nose bridge line between the first guide wheels 102 and the second guide wheels 103 is pressed. From this, two second wire wheels 103 all can compress tightly the nose bridge line on second wire wheel 103, and wire unit 1 is better to the guide effect of nose bridge line. The wire unit 1 further includes a second slider 104, and a plurality of second wire wheels 103 are mounted to the second slider 104. The second mounting base 101 is provided with a first sliding slot 1011, the first sliding slot 1011 extends along the second direction, and the second sliding block 104 is in sliding fit with the first sliding slot 1011.
As shown in fig. 3, the number of the second sliders 104 is the same as that of the second wire guide wheels 103, and the number of the first sliding grooves 1011 is the same as that of the second sliders 104. The two first sliding grooves 1011 extend along the up-down direction and are arranged at intervals in the left-right direction, the second sliding blocks 104 are in sliding fit with the corresponding first sliding grooves 1011, and the second guide wire wheels 103 are mounted on the corresponding second sliding blocks 104. Therefore, the two second guide wheels 103 slide on the second mounting seat 101 relatively independently, so that different second guide wheels 103 can be flexibly controlled to compress the nose bridge line to different degrees or the same degree, and the universality is higher.
In some embodiments, the mask nose bridge line cutting device 100 further comprises an elastic member and a threaded connection rod, wherein the elastic member is disposed in the first sliding groove 1011. A first end of the elastic member is connected to the second mounting base 101 and a second end of the elastic member is connected to the second slider 104, the elastic member being in a deformed state so as to constantly bring the second slider 104 to a position away from the first wire guide wheel 102. The second mounting seat 101 is provided with a first threaded hole communicated with the first sliding groove 1011, and the threaded connecting rod is in threaded fit with the first threaded hole and stops the second slider 104.
As shown in fig. 1 to 3, one end of the elastic member is connected to the lower side of the second slider 104, and the other end of the elastic member is connected to the lower end wall (not shown) of the first sliding groove 1011. The first threaded hole is located above the second slider 104, and the axial direction of the first threaded hole is the up-down direction. The threaded connection rod is matched with the first threaded hole, and the lower end of the threaded connection rod is located in the first sliding groove 1011. The elastic member usually drives the second slider 104 to move upward so that the second slider 104 is usually abutted to the lower end of the threaded connection rod. That is, the threaded connection rod limits the second slider 104 to move upwards, the elastic member limits the second slider 104 to move downwards, and the threaded connection rod and the elastic member ensure that the position of the second wire guide wheel 103 on the second slider 104 is stable in the vertical direction.
Thereby, the threaded connection rod moves down, which in turn pushes the second slider 104 to move down so that the second wire guide wheel 103 approaches the first wire guide wheel 102. The threaded connecting rod moves upwards, and the elastic member pushes the second slider 104 to move upwards, so that the second wire guide wheel 103 is far away from the first wire guide wheel 102. The sliding adjustment of the second wire guide wheel 103 is convenient and fast.
In some embodiments, one of the first sliding groove 1011 and the second sliding block 104 is provided with a limiting portion, and the limiting portion cooperates with the other of the first sliding groove 1011 and the second sliding block 104 to prevent the second sliding block 104 from separating from the notch of the first sliding groove 1011 and the first sliding groove 1011. One end of the first sliding chute 1011 is open, the second mounting seat 101 is provided with a second baffle 105 for closing the opening of the first sliding chute 1011, and the first threaded hole is formed in the second baffle 105. As shown in fig. 1 to 3, the two first sliding chutes 1011 are both provided with openings at the upper ends, that is, the upper end wall of each first sliding chute 1011 is provided with the through opening. Thereby, the second slider 104 is conveniently in sliding fit in the corresponding first sliding groove 1011 from the upper end opening. The second stopper 105 is detachably mounted on the second mounting seat 101 and blocks the upper end openings of the two first sliding grooves 1011, thereby preventing the second slider 104 from coming off the corresponding first sliding grooves 1011.
As shown in fig. 2, the threaded connection rod is a seventh bolt, the seventh bolt is in threaded fit with the first threaded hole, and the lower end of the seventh bolt is located in the first sliding groove 1011 and abuts against the upper side of the second slider 104 (not shown in the figure). The elastic member is a spring, the spring is disposed in the first sliding slot 1011, a lower end of the spring abuts against a lower end wall of the first sliding slot 1011, an upper end of the spring abuts against a lower side of the second slider 104, and the spring is in a deformed state so as to push the second slider 104 to a position away from the first wire guide wheel 102. Therefore, the second wire guide wheel 103 is close to and far from the first wire guide wheel 102 through the rotation of the seventh bolt in the first threaded hole, and the adjustment mode of the second wire guide wheel 103 is simple and quick.
It should be noted that, the elastic member may also be an extension spring, and the extension spring is located in the first sliding groove 1011 and is sleeved on the seventh bolt. The lower end of the extension spring is connected to the upper side of the second slider 104, and the upper end of the extension spring is connected to the lower side of the second stopper 105.

As shown in fig. 1 and 2, the first line pressing roller 202 and the second line pressing roller 203 are sequentially arranged from top to bottom, the first motor 204 is installed on the base, and the first motor 204 is connected to the second line pressing roller 203 to drive the second line pressing roller 203 to rotate, so as to convey the nose bridge line between the first line pressing roller 202 and the second line pressing roller 203 to the cutting unit 3. The second slide groove 2011 extends in the up-down direction, the upper end opening of the second slide groove 2011 is provided, and the first slider 205 is slidably fitted in the second slide groove 2011 through the upper end opening.
