Description

Technical Field

[0001] The invention relates to the technical field of wire mesh shearing and processing equipment, and in particular to a high-precision counting flat mesh shearing machine suitable for flexible wire mesh. Background Art

[0002] The wire mesh 40 is flattened by the flattening machine 10 and then transported to the wire shearing machine 20. The counting wheel 312 provided on the wire shearing machine 20 is used to count the number of mesh holes 41 of the wire mesh 40 directly below it. Under normal circumstances, the teeth 3122 of the counting wheel 312 will be inserted into the mesh holes 41 of the wire mesh 40. Figure 1 As shown, the screen 40 drives the counting wheel 312 to rotate, and then the next tooth portion 3122 of the counting wheel 312 enters the next mesh 41 of the screen 40, and the cycle is repeated to achieve counting. Since the screen 40 drives the counting wheel 312 to rotate, there will be a situation where the tooth portion 3122 of the counting wheel 312 and the mesh 41 of the screen 40 are not properly engaged, and the sizes of the mesh 41 of the screen 40 are not exactly the same. The tooth portion 3122 of the counting wheel 312 is not inserted into the mesh 41 of the screen 40, but pressed on the twisted pattern 42 of the screen 40, as shown in FIG. Figure 2 As shown, it causes counting errors. Figure 3 For the flexible screen 40, the counting wheel 312 will press against the screen 40 when rotating, causing the screen 40 to deform, resulting in the teeth of the counting wheel 312 and the screen 40 being disengaged, and also causing counting errors.

[0031] See also Figures 1 to 13The embodiment of the present invention provides a high-precision counting flat mesh shearing machine suitable for flexible wire mesh, including a flat mesh machine 10, a shearing machine 20, a counting control component 30, and a net supporting component 50. The flat mesh machine 10 is used to flatten a wire mesh 40 and then convey it to the shearing machine 20. The shearing machine 20 is used to cut the wire mesh 40 conveyed by the flat mesh machine 10.

The length of the toothed portion 3122 is smaller than the diameter of the mesh 41 of the wire mesh 40. The clutch component 313 includes a driving gear 3131, a driven gear 3132, a transmission chain 3133, a retaining ring 3134, a spring 3135, and a friction plate 3136. The driving gear 3131 is sleeved on an output end of the dual-axis motor 33, the driven gear 3132 is installed on the counting shaft 311, and the driven gear 3132 is rotatably connected to the counting shaft 311. The driving gear 3131 and the driven gear 3132 are connected through the transmission chain 3133. The retaining ring 3134 is fixedly installed on the counting shaft 311, and the spring 3135 is sleeved on the counting shaft 311. , one end of the spring 3135 is fixedly connected to the retaining ring 3134, and the other end of the spring 3135 is fixedly connected to the friction plate 3136. The friction plate 3136 is installed on the counting shaft 311 and is located between the spring 3135 and the driven gear 3132. The friction plate 3136 can move axially along the counting shaft 311 and rotate synchronously with the counting shaft 311. The net supporting assembly 50 includes a slide bar 51 and a net supporting member 52. The slide bar 51 is fixedly connected to the fuselage 21. The slide bar 51 is located directly below the counting control assembly 30. The slide bar 51 is parallel to the counting shaft 311. The cross-section of the slide bar 51 is rectangular. The net supporting member 52 is installed on the slide bar 51. The net supporting member 52 is in the shape of a long strip. The net supporting member 52 and the slide bar 51 are arranged vertically relative to each other. The upper surfaces of the two ends of the net supporting member 52 are provided with chamfers.There are multiple net support members 52, and each counting wheel 312 is provided with a net support member 52 on both sides.

[0032] The left, right, front and back mentioned here are based on: Figure 5 The left side of the paper is the front, that is Figure 5 The direction in which the flat screen machine 10 points to the screen cutting machine 20 is the front, and the direction in which the flat screen machine 10 points to the screen cutting machine 20 is the back. Figure 5 The bottom of the paper is on the left. Figure 5 The top middle of the paper is right.

[0033] The teeth 3122 of the counting wheel 312 can be inserted into the meshes 41 of the screen 40. Each time the screen 40 moves forward one mesh 41, the counting wheel 312 is driven to rotate, and then the next teeth 3122 of the counting wheel 312 enters the next mesh 41 of the screen 40, and the counting is repeated in this way.

[0034] In this embodiment, a dual-axis motor 33 is used to actively drive the counting shaft 311 to rotate, so that the counting wheel 312 actively rotates. Since the speed of the dual-axis motor 33 is faster than that of the screen 40, see Figure 4 When the teeth 3122 of the counting wheel 312 are inserted into the mesh holes 41 of the wire mesh 40, it can be ensured that the rear end of the teeth 3122 of the counting wheel 312 always presses against the rear end of the mesh holes 41 of the wire mesh 40, and the front end of the teeth 3122 of the counting wheel 312 and the front end of the mesh holes 41 of the wire mesh 40 can always ensure a sufficient distance, thereby avoiding the teeth 3122 of the counting wheel 312 from pressing on the wire mesh 40 outside the mesh holes 41 of the wire mesh 40. The present invention adopts a dual-axis motor 33 to actively drive the counting wheel 312 to rotate, thereby avoiding the problem of the teeth 3122 of the counting wheel 312 pressing on the wire mesh 40.

[0035] In the above embodiment, since the speed of the dual-axis motor 33 is faster than that of the wire mesh 40, the tooth portion 3122 of the counting wheel 312 will disengage from the mesh 41 of the wire mesh 40, and the dual-axis motor 33 is connected to the counting wheel 312 through the clutch component 313. When the force between the counting wheel 312 and the wire mesh 40 is greater than the friction force between the friction plate 3136 and the driven gear 3132, the friction plate 3136 and the driven gear 3132 slip, so that the force between the counting wheel 312 and the wire mesh 40 no longer increases, thereby avoiding the problem that the tooth portion 3122 of the counting wheel 312 will disengage from the mesh 41 of the wire mesh 40. The dual-axis motor 33 indirectly drives the counting wheel 312 through the clutch component 313, thereby avoiding the problem that the tooth portion 3122 of the counting wheel 312 will disengage from the mesh 41 of the wire mesh 40, thereby avoiding the counting error of the counting control component 30 and improving the counting accuracy of the counting control component 30.

[0036] The present invention provides mesh supporting members 52 on both sides of the counting wheel 312 to support the screen 40 and prevent the screen 40 from deforming, thereby avoiding the counting wheel 312 and the screen 40 from being disengaged, thereby avoiding counting errors of the counting control component 30 and improving the counting accuracy of the counting control component 30.

[0037] See also Figures 1 to 13 Furthermore, a slide groove is provided in the middle of the net supporting member 52, and the cross-sectional shape of the slide groove matches the cross-sectional shape of the slide rod 51, so that the net supporting member 52 is slidably connected to the slide rod 51 through the slide groove.

[0038] The mesh holes 41 of the wire meshes 40 of different specifications have different sizes. The mesh supporting member 52 is slidably connected to the sliding rod 51 to adapt to the change of the counting position of the mesh holes 41 of the wire meshes 40 of different specifications.

[0039] See also Figures 1 to 13 The counting assembly 31 further includes a linear bearing 314 , which is coaxially mounted on the counting shaft 311 , and the counting wheel 312 is fixedly connected to one end of the linear bearing 314 .

[0040] In this embodiment, the linear bearing 314 can slide along the axial direction of the counting shaft 311 and drive the counting wheel 312 to slide along the axial direction of the counting shaft 311. Because the mesh holes 41 of different screens 40 are of different sizes, or the mesh holes 41 of the same screen 40 are not exactly the same size, it is necessary for the counting wheel 312 to slide left and right along the counting shaft 311 when counting the mesh holes 41 of the screen 40 to adapt to the position changes of the mesh holes 41 of the screen 40.

[0041] See also Figures 1 to 13 Furthermore, a snap-fit ​​groove 3111 is provided on the outer ring wall of the counting shaft 311 and passes through along its axis, and a mounting groove 3123 is provided on one side of the counting wheel 312, the bottom of the mounting groove 3123 is located at the center of the counting wheel 312, the width of the mounting groove 3123 is equivalent to the diameter of the counting shaft 311, and the bottom of the mounting groove 3123 is also provided with a snap-in portion 3124 matching the snap-fit ​​groove 3111.

[0042] The counting wheel 312 is inserted into the counting shaft 311 through the installation groove 3123 , and the snap-in portion 3124 is snap-fitted into the snap-in groove 3111 , so that the counting shaft 311 and the counting wheel 312 rotate synchronously, and the installation is convenient.

[0043] See also Figures 1 to 13 Furthermore, the counting component 31 also includes a support rod 315 and a first hydraulic cylinder 316. The front end of the support rod 315 is hinged to the fuselage 21, the rear end of the support rod 315 is fixedly connected to one end of the counting wheel frame 32, the fixed end of the first hydraulic cylinder 316 is connected to the base 25, and the telescopic end of the first hydraulic cylinder 316 is hinged to the rear end of the support rod 315.

[0044] In this embodiment, the first hydraulic cylinder 316 contracts, the counting wheel frame 32 descends to the working position, and the counting wheel 312 starts counting. The first hydraulic cylinder 316 extends, the counting wheel frame 32 rises, and the counting wheel 312 stops counting.

[0045] See also Figures 1 to 13 Furthermore, the mesh shearing machine 20 also includes a mesh pressing roller tube 22 and a second hydraulic cylinder 23. The mesh pressing roller tube 22 is arranged on the upper part of the machine body 21 parallel to the counting axis 311. The fixed end of the second hydraulic cylinder 23 is connected to the machine body 21, and the telescopic end of the second hydraulic cylinder 23 is connected to the mesh pressing roller tube 22. The mesh pressing roller tube 22 can rotate around its axis.

[0046] In this embodiment, the screen pressing roller tube 22 can ensure that the screen 40 remains flat when being cut, ensuring that it is cut evenly.

[0047] See also Figures 1 to 13 Furthermore, the high-precision counting flat mesh shearing machine suitable for flexible wire mesh also includes an adjustment component 60, which is used to adjust the angle between the flat mesh machine 10 and the shearing machine 20, and then adjust the angle between the shearing knife 24 of the shearing machine 20 and the wire mesh 40.

[0048] See also Figures 1 to 13 Further, the net shearing machine 20 also includes a base 25, the base 25 is two, the two bases 25 are symmetrically fixed at the two ends of the fuselage 21, the two bases 25 are arranged along the length direction of the fuselage 21, the bottom end surface of the left base 25 is installed with a roller 26, and a track 27 is fixedly installed on the ground below the left base 25, the track 27 is arranged along the front and rear direction of the base 25, the roller 26 is rollingly connected to the track 27, and the bottom end surface of the right base 25 is rotatably connected to the ground. The flat net machine 10 includes a body 11, a body 1 The left and right ends of 1 are relatively fixed to the ground, the length direction of the body 11 of the flat mesh machine 10 is arranged in the same direction as the length direction of the body 21 of the net shearing machine 20, the deviation adjustment component 60 includes a screw motor 61, the fixed end of the screw motor 61 is fixedly installed on the left end of the body 11 of the flat mesh machine 10, the telescopic end of the screw motor 61 is hinged to the left base 25 of the net shearing machine 20, the telescopic end of the screw motor 61 is extended or contracted in the horizontal direction, so as to drive the left base 25 to move forward or backward relative to the ground through the telescopic end of the screw motor 61.

[0049] When using the mesh shearing machine 20 to cut the wire mesh 40, combined with Fig. 9 In the case of straight cutting, the shearing knife 24 cuts at the middle of the same row of twisted patterns 42 of the wire mesh 40. However, during the shearing process of the wire mesh 40, the wire mesh 40 passes through the flat mesh machine 10 and enters the shearing machine 20. Since the wire mesh 40 itself may not be rectangular, or the wire mesh 40 is in an inclined state when entering the shearing machine 20, and the shearing knife 24 of the shearing machine 20 is straight, combined with Fig.10 One end of the shearing knife 24 may cut the wire mesh 40 at the upper end of the same row of twisted patterns 42 of the wire mesh 40, while the other end of the shearing knife 24 may cut the wire mesh 40 at the lower end of the same row of twisted patterns 42 of the wire mesh 40, resulting in the wire mesh 40 being cut off-center.

[0050] The wire mesh 40 is flattened by the flattening machine 10 and then transported to the wire shearing machine 20. When the wire mesh 40 deviates, since the shearing knife 24 is straight, Fig.11 As shown, at this time, the wire mesh 40 will be cut off, and the angle between the wire cutting machine 20 and the flat wire machine 10 is adjusted by the screw motor 61, as shown in FIG. Fig.12 As shown, the shearing knife 24 is adapted to match the angle of the same row of twisted patterns 42 of the wire mesh 40 being cut, thereby ensuring that the wire mesh 40 is cut straight.

[0051] In this embodiment, a screw motor 61 is arranged between the flat mesh machine 10 and the mesh shearing machine 20. When the mesh shearing machine 20 shears the wire mesh 40 at an angle, the screw motor 61 is used to adjust the angle between the flat mesh machine 10 and the mesh shearing machine 20, thereby adjusting the angle between the wire mesh 40 and the shearing knife 24 of the mesh shearing machine 20 and the wire mesh 40 to ensure that the wire mesh 40 is cut straight.

[0052] See also Figures 1 to 13 Furthermore, the counting control component 30 also includes a microprocessor 34, and the counting component 31 also includes an encoder 317. The encoder 317 is installed on the counting shaft 311 and rotates synchronously with the counting shaft 311. The encoder 317 is used to detect the number of rotations of the counting wheel 312 and output a detection signal. The microprocessor 34 is connected to the two encoders 317 respectively, and the microprocessor 34 is connected to the screw motor 61.

[0053] The wire mesh 40 is flattened by the flattening machine 10 and then conveyed to the wire shearing machine 20. When the wire mesh 40 deviates, the number of holes of the wire mesh 40 passing through the two counting components 31 is different. The two counting wheels 312 respectively measure the number of holes of the wire mesh 40 directly below them. Since the number of holes counted by the counting wheels 312 on both sides is different, the number of revolutions of the corresponding counting shaft 311 is also different. The corresponding encoder 317 detects the number of revolutions of the counting shaft 311 and converts it into an electrical signal representing the physical length and conveys it to the microprocessor 34. The microprocessor 34 here has a built-in comparison circuit, which can receive the electrical signals output by the two encoders 317 and calculate the difference between the two electrical signals, and then control the extension or shortening of the lead screw motor 61 according to the calculated difference until the number of holes counted by the two counting wheels 312 is equal.

[0054] In this embodiment, the microprocessor 34 automatically detects whether the wire mesh 40 is deviated based on the information provided by the two counting components 31, and automatically adjusts the angle between the flat screen machine 10 and the wire shearing machine 20 based on the deviation amount provided by the two counting components 31, and then adjusts the angle between the shearing knife 24 of the wire shearing machine 20 and the wire mesh 40 to ensure that the wire mesh 40 is cut straight.

[0055] See also Figures 1 to 13 , further, the screw motor 61 is a linear screw motor 61.
