Specific implementation mode

[0023] The following combines the attached Figure 1 To the attached Figure 5 The principle and features of the present invention are described. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] A silk screen automatic winding and discharging device includes a frame 1, a conveying mechanism 2, a cutting mechanism 3, and a winding and discharging mechanism 4 that are sequentially arranged on the frame 1, and also includes a pressure roller assembly 23 and a control box 27. The conveying mechanism 2 is used to stably convey the woven silk screen to the winding and discharging mechanism 4. The winding and discharging mechanism 4 winds the silk screen. After winding to a specified length, it is cut by the cutting mechanism 3. After cutting, the winding and discharging mechanism 4 automatically pushes the web roll to complete the discharging. The pressure roller assembly 23 is arranged between the cutting mechanism 3 and the winding and discharging mechanism 4, and presses on the wound web surface with pressure, so that the web roll is wound more evenly and tightly. The control box 27 is provided with a control system, and the control box 27 is provided with a display screen and control buttons for parameter display and automatic control of the device.

[0025] The conveying mechanism 2 includes a conveying roller set 5, a hanging roller 10, and a clamping roller set 13 that are arranged in parallel. The conveying roller set 5 is rotatably connected to the frame 1, and the clamping roller set 13 is arranged at the feeding end of the cutting mechanism 3.

[0026] The conveying roller group 5 includes a first conveying roller 11, a second conveying roller 12 and a third conveying roller 26 which are arranged in parallel. Among them, the first conveying roller 11 and the second conveying roller 12 are arranged on both sides of the hanging roller 10, and the third conveying roller 26 is arranged between the second conveying roller 12 and the clamping roller group 13. In order to limit the wire mesh and prevent it from running off, in one embodiment, a number of spiked wheels can be arranged on the third conveying roller 26. In order to keep the woven wire mesh in good tightness during the conveying process, conveying rollers can be arranged at appropriate positions during the conveying process. In one embodiment, a conveying roller is arranged between the third conveying roller 26 and the clamping roller group 13.

[0027] In order to calculate the length of the wire mesh, a device for measuring the length of the wire mesh can be arranged on the frame 1. In one embodiment, a proximity switch is arranged at one end of the third conveying roller 26 for measuring the number of rotations of the third conveying roller 26 and calculating the length of the wire mesh. Of course, devices for measuring the length of the wire mesh such as proximity switches can be arranged at any position convenient for collecting the length of the wire mesh.

[0028] The hanging roller 10 presses down the wire mesh by its own weight. In one embodiment, in order to increase the weight of the hanging roller 10, counterweight blocks can be connected to both ends of it. As Figure 1 shown, after the woven wire mesh is output from the weaving device, it first passes through the first conveying roller 11, then bypasses the hanging roller 10 downward and then bypasses the second conveying roller 12 upward. As the woven wire mesh is continuously output from the weaving device, the hanging roller 10 presses the wire mesh downward by its own weight, playing a role in adjusting the length and tension of the wire mesh on the conveying network.

[0029] The clamping roller group 13 includes a first clamping roller 14 and a second clamping roller 15 which are closely arranged. When the wire mesh is cut, the cutting mechanism 3 has a certain pulling force on it. By arranging the clamping roller group 13 to clamp the wire mesh, smooth cutting is ensured.

[0030] The winding and blanking mechanism 4 includes a winding roller 6, a baffle 7, a push plate 8 and a slide rail 9. One end of the winding roller 6 is connected to the baffle 7, and the other end is rotatably connected to the frame 1 and the winding roller 6 is driven to rotate by a motor. The push plate 8 is slidably connected to the winding roller 6. The bottom end of the baffle 7 is rotatably connected to the frame 1, and the baffle 7 rotates in the blanking direction under the drive of an external force. The push plate 8 moves along the slide rail 9 under the drive of an external force. The external force drive mentioned here can be a common drive structure in mechanical structures. In one embodiment, a driving cylinder is arranged between the baffle 7 and the frame 1, the telescopic end of the driving cylinder is connected to the baffle 7, and the other end is fixedly connected to the frame 1. In one embodiment, the bottom of the push plate 8 is connected to a screw rod driving device, the output end of the driving motor is connected to the screw rod, the push plate 8 is fixedly connected to the nut sleeve, and the driving motor rotates to drive the screw rod to rotate, further driving the nut sleeve and the push plate 8 fixedly connected thereto to achieve reciprocating movement.

[0031] During the winding process, the diameter of the mesh roll gradually increases as winding progresses. By collecting the diameter of the mesh roll and feeding it to the control box 27, the control system inside the control box 27 continuously adjusts the rotation speed of the winding roller 6 to ensure a constant tension of the wire mesh during the winding process, thereby ensuring the stability of the winding process. The method of collecting the diameter of the mesh roll can be to measure the length of the wire mesh and then calculate the diameter of the mesh roll, or it can be collected by installing an industrial camera or corresponding sensors on the frame 1, etc.

[0032] The cutting mechanism 3 includes a cutter assembly 16 and a driving mechanism 17 for driving the cutter assembly 16 to move horizontally.

[0033] The driving mechanism 17 includes a first driving motor 18, a gear 19, and a rack 20 meshing with the gear 19. The gear 19 is arranged at the output end of the first driving motor 18, the rack 20 is fixedly arranged on the frame 1, and the rack 20 is arranged in parallel with the conveyor roller group 5. When the winding reaches the set length, the first driving motor 18 rotates, driving the gear 19 to move along the rack 20, driving the cutter assembly 16 to move, and completing the cutting.

[0034] The cutter assembly 16 includes an upper cutter 21, a lower cutter 22, and a second driving motor 28. The second driving motor 28 can drive the upper cutter 21 and the lower cutter 22 to approach or separate from each other. In one embodiment, the upper cutter 21 and the lower cutter 22 are arranged at a certain angle to improve the smoothness of cutting. In one embodiment, the second driving motor 28 includes a cam arranged at its output end. When cutting is required after the winding is completed, the second driving motor 28 rotates, driving the cam to rotate. The cam pushes the upper cutter 21 to move downward and approach the lower cutter 22, and then the driving mechanism 17 drives the cutter assembly 16 to move horizontally to complete the cutting.

[0035] By collecting the length of the wire mesh or the diameter of the mesh roll, the control system inside the control box 27 automatically determines that the winding is completed. At this time, the control system controls the cutting mechanism 3 to cut the wire mesh. After the cutting is completed, the control system controls the driving device to drive the push plate 8 to move along the slide rail 9, pushing the mesh roll in the direction of the baffle 7. At the same time, the control system controls the driving device to drive the baffle 7 to rotate and fall down around its bottom end. The push plate 8 continues to push the mesh roll until the mesh roll is pushed off the winding roller 6. Then the push plate 8 and the baffle 7 automatically reset and wait for the next winding operation. Devices such as packing boxes and transport trucks can be placed at the place where the mesh roll falls to facilitate the packaging or transportation of the mesh roll.

[0036] The pressure roller assembly 23 includes a pressure roller 24 arranged in parallel with the conveyor roller group 5, and roller brackets 25 provided at both ends of the pressure roller 24. One end of the roller bracket 25 is rotatably connected to the frame 1, and the other end of the roller bracket 25 is rotatably connected to the pressure roller 24. The roller bracket 25 can be rotated under the drive of an external force, so that the pressure roller 24 presses the wire mesh wound on the winding roller 6 with pressure, making the wound wire mesh roll compact. In one embodiment, a driving cylinder is provided between the roller bracket 25 and the frame 1. The telescopic end of the driving cylinder is connected to the roller bracket 25, and the other end of the driving cylinder is connected to the frame 1. When the diameter of the wire mesh roll gradually increases, the control system automatically adjusts the telescopic length of the driving cylinder, and further adjusts the pressure of the pressure roller 24 on the wire mesh roll, ensuring uniform winding and further ensuring that the wound wire mesh roll is compact and does not come loose.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
