Description

Technical Field

[0001] The present invention belongs to the field of textile machinery, and particularly relates to a device for manufacturing a wide-width spiral net. Background Art

[0002] A spiral net is a common filtering material, usually made of high molecular plastics such as PP and polyester fibers, and has advantages such as high temperature resistance and acid and alkali resistance, and is widely used in the processing of various filtering materials. Chinese Patent CN02203004.2 discloses a spiral net structure. Usually, in the processing process of a spiral net, it is necessary to first form a spiral-structured ring by a single filament through a ring winding machine, then overlap the spiral-structured rings on a net connecting machine, and then the net connecting machine automatically introduces a single filament into the overlapping rings to form a spiral net sheet. Each spiral net sheet is composed of 30 left-handed spiral-structured rings and 30 right-handed spiral-structured rings connected in parallel, with a length of about 20 cm. For the specific structure, see Figure 1 However, when a spiral net is used as a filtering material, a large area is required. The traditional equipment cannot produce a long enough spiral net at one time, and can only splice a longer spiral net through a splicing process. In the traditional splicing process, workers stand and operate facing the net connecting machine. The net connecting machine is responsible for producing spiral net sheets, and there is a net connecting platform downstream for connecting the sheets into a net. The net connecting platform has a certain width and height. Therefore, there are certain requirements for the height of workers, and it is necessary to bend down and manually lead the wire for operation, which is time-consuming and laborious and has low efficiency. Summary of the Invention

[0006] An automatic wire guiding mechanism, arranged on the side of the spreading platform, configured to automatically feed or retract the wire by means of a control module;

[0007] A winding mechanism, located downstream of the movable work station, configured to provide a tension force to wind up the continuously spliced spiral net.

[0008] In the above technical scheme, preferably, a sheet locator and a positioning line are arranged on the spreading platform for fixing the position of the spiral net sheet in the working area.

[0009] In the above technical solution, preferably, the operation platform further includes a control system that is signal-connected to the movable work station and the winding mechanism, and an input device for inputting command signals to the control system.

[0010] In the above technical solution, preferably, the operation platform further includes a frame, on which an X-direction sliding rail extending in the X-axis direction and a Y-direction sliding rail extending in the Y-axis direction are provided. The movable work station is slidably connected to the X-direction sliding rail and is configured to be movable along the Y-axis on the Y-direction sliding rail.

[0011] In the above technical solution, preferably, the operation platform further includes a driving mechanism for driving the movable work station to slide along the Y-direction sliding rail or the X-direction sliding rail, and the driving mechanism is signal-connected to the control system.

[0012] In the above technical solution, preferably, the automatic wire guiding mechanism includes a set of first wire guiding rollers, a driving device for controlling the forward or backward movement of the single wire, and a cutting device for cutting the single wire.

[0013] In the above technical solution, preferably, the cutting device includes a positioning cutter and an induction detector, and the cutter and the induction detector are respectively located on both sides of the operation platform.

[0014] In the above technical solution, preferably, clamping and conveying mechanisms are provided on both sides of the spreading platform, and the clamping and conveying mechanisms are signal-connected to the control system to realize the intermittent conveying of the spiral net on the operation platform.

[0015] In the above technical solution, preferably, the operation platform further includes detection mechanisms located on the left and right sides of the spiral net. The detection mechanisms are signal-connected to the control system, and the detection mechanisms are configured to emit an alarm signal when there are some mesh loops that are missed or mis-pierced in two spliced spiral nets.

[0016] In the above technical solution, preferably, the input device is an operation handle, and the operation handle is provided on the movable work station.

[0017] In the above technical solution, preferably, at least part of the moving path of the movable work station is located within the projection of the spreading platform on the horizontal plane.

[0018] Furthermore, a weight sensor and a warning light are also provided on the automatic wire guiding mechanism. When the weight of the wire cake on the wire guiding mechanism decreases to a certain value, the warning light lights up to remind the worker to replace the wire cake in time.

[0019] In the above technical solution, preferably, a pair of second wire guiding rollers are further arranged between the spreading platform and the movable working station, and the second wire guiding rollers are located downstream of the automatic wire guiding mechanism.

[0021] The operation platform of the present invention is arranged downstream of the spiral mesh networking machine.

Once the operator makes an operational error, the wires can be retracted by the automatic wire guiding mechanism and then fed again, reducing the running of personnel and improving the production efficiency; The automatic detection device can perform misaligned loop detection on the spliced spiral mesh. Once quality problems such as missed threading or wrong threading are found, it can help workers make timely corrections and improve the product quality. Description of the Drawings

[0028] To describe in detail the technical content, structural features, achieved objectives and effects of the invention, the following will be described in detail in combination with embodiments and with reference to the drawings. Among them, the "front", "rear", "left", and "right" described in the specification are based on the orientations observed by the operator sitting on the movable working station, that is, Figure 2 in the upper part of the drawing is "front", the lower part is "rear", the left side is "left", and the right side is "right".

[0029] As Figure 2 , 3 , shown in Figure 4, a spiral mesh networking operation platform includes the following components:

[0030] Frame 10, used to support the operation platform and connect the following components;

[0031] Spreading platform 1, having a tabletop extending in the X-Y plane, the first spiral mesh sheet 21 and the second spiral mesh sheet 22 to be spliced are laid flat on the spreading platform 1, positioning lines are drawn on the spreading platform 1, and the operator overlaps the edge parts of the first spiral mesh sheet 21 and the second spiral mesh sheet 22 according to the requirements of the sheet positioner and the positioning lines for subsequent wire threading;

[0032] The movable working station 2 is for the operator to sit on. The movable working station 2 is connected to the frame 10 through an X-direction slide rail 12 and a Y-direction slide rail 11, and can be manually operated to move along the X-Y plane. The Y-direction slide rail 11 is arranged on the frame 10 or on the ground. The X-direction slide rail 12 is slidably connected to the Y-direction slide rail through a lifting device 17. The movable working station 2 is slidably connected to the X-direction slide rail 12 along the X direction. The height of the working station can be adjusted through the lifting device 17 to meet the needs of workers of different heights. The operation platform further includes a driving mechanism for driving the movable working station 2 to slide along the X-direction slide rail 12 and the Y-direction slide rail 11. The driving mechanism can be a power component such as a cylinder or a motor. The specific connection structure of the movable working station and the driving mechanism can be realized in a variety of implementation manners, as long as it can realize free movement in the front, back, left, and right directions;

[0033] The automatic wire guiding mechanism 6 is arranged on the left side of the spreading platform 1. The automatic wire guiding mechanism 6 includes a set of first wire guiding rollers 3 and a driving device for controlling the feeding or retraction of the single wire 23, and further includes a positioning cutter 14 for cutting off the single wire after wire threading is completed. An induction detector 15 is arranged on the right side of the spreading platform 1. Since the wire 23 used for splicing the spiral net is a high-molecular material with a certain hardness, the operator only needs to thread the single wire 23 into the wire loops at the overlapping part of the first spiral net sheet 21 and the second spiral net 22 sheet, and the wire 23 can be threaded into the wire loops through the automatic wire feeding of the automatic wire guiding mechanism 6. Once the operator makes an operational error, the wire can be retracted by controlling the automatic wire guiding mechanism and then fed again, and finally the wire 23 can pass through all the overlapping wire loops. When the wire threading of a row of wire loops is completed, after the induction detector 15 on the right side of the operation platform senses that the single wire 23 has reached the position, the positioning cutter 14 can automatically cut off the wire on the left side of the operation platform; in addition, a weight sensor and a warning light are configured on the rack for mounting the wire cake 26, and are set to turn on the warning light when the weight of the wire cake is lower than a certain value, reminding the worker to replace the wire cake in time;

[0034] The clamping and conveying mechanism 16 is arranged on both sides of the operation platform, and is used to fix the second spiral net sheet 22 during the splicing process, and to cooperate with the winding mechanism 8 to complete the winding or retraction of the spiral net after the splicing process is completed;

[0035] The winding mechanism 8 is located downstream of the movable working station 2 and is configured to provide a tension force to wind the spliced spiral net. The winding mechanism winds the spiral net intermittently, winds a fixed length each time, and stops winding during wire threading;

[0036] A control system and an input device for inputting command signals to the control system. The control system is signal-connected to the drive mechanism of the movable work station, the drive device of the automatic wire guiding mechanism 6, the clamping and conveying mechanism 16, and the winding mechanism. The input device may include an operating handle 9 for controlling the operation of the drive mechanism and a control module for controlling the operation of the automatic wire guiding mechanism. The control module is a switch. For ease of operation, the operating handle 9 is preferably integrally provided on the movable work station 2. An operator can sit on the movable work station 2 and move forward, backward, left, and right through the operating handle 9. The control modules of the clamping and conveying mechanism 16 and the automatic wire guiding mechanism can be integrated on the operating handle 9 or provided on the spreading platform 1, and it is advisable to design it for the convenience of workers' operation.

[0037] For the convenience of the operator's operation, a seat is provided on the movable work station 2 and is set at a relatively comfortable height downstream of the spreading platform. An acrylic cover plate 13 is provided on one side of the spreading platform close to the movable work station 2. The acrylic cover plate 13 separates the movable work station 2 from the transmission path of the spiral net. The completed continuous spiral net passes under the movable work station 2. A plurality of guide rollers 7 for limiting are provided on the frame 10. The completed continuous spiral net is conveyed by the guide rollers 7 and wound by the winding mechanism 8.

[0038] A pair of second wire guiding rollers 19 are also provided between the spreading platform 1 and the movable work station 2. The second wire guiding rollers 19 are located downstream of the wire threading position 25 and the automatic wire guiding mechanism 6. The second wire guiding rollers 19 and the winding mechanism 8 jointly tension and wind the completed continuous spiral net.

[0039] The operating platform further includes a detection mechanism configured to emit an alarm signal when there are some missing wire loops in the two spliced spiral nets. The detection mechanism includes a light emitter 4 respectively provided on the left side of the spiral net and a receiver 5 located on the right side of the spiral net. In a preferred embodiment of the present invention, the light emitter 4 is a laser generator and the receiver 5 is a laser receiver.

[0040] In this embodiment, the detection mechanism is located below the second wire guide roller 19. After the first spiral mesh sheet 21 and the second spiral mesh sheet 22 are joined at the wire threading position 25, the winding mechanism 8 winds up a section of the spliced spiral mesh, causing the wire threading position 25 to reach the detection mechanism. Due to the second wire guide roller 19 and the winding mechanism 8, the spiral mesh is tensioned, and the wire loop where the wire threading position 25 is located is stretched. If there is no missed wire threading, there will be a large space in the middle of the wire loop for the detection light emitted by the light emitter 4 to pass through smoothly. However, if some wire loops are missed, there will be individual wire loops without tension, causing the outer contour of the wire loops to be unevenly arranged in the Y direction, thereby blocking the detection light emitted by the light emitter 4 and causing the intensity of the detection light received by the receiver 5 to be lower than the set threshold, resulting in an abnormal detection result alarm. The center of the wire loops located upstream or downstream of the wire threading position 25 can be used as the detection position 24. The winding mechanism 8 is driven by a stepping motor, and the stepping length is based on the length of a spiral mesh sheet of any length set according to parameters in the X direction. After each splicing is completed, the operator manually controls a detection, checking both ends of the wire threading holes. At this time, when the detection position of the spiral mesh is just aligned with the detection mechanism and the detection mechanism does not alarm, a winding signal is sent to the winding mechanism 8, and the winding wire distance is exactly the length of a spiral mesh sheet in the X direction.

[0041] The plexiglass cover plate 13 is located in front of the second wire guide roller 19 and the detection mechanism and behind the movable station 2. The plexiglass cover plate 13 is set to be transparent and detachable, which can protect the spliced spiral mesh from being touched by the legs and feet of workers, and at the same time protect the safety of workers. Through the cover plate, the spliced spiral mesh can also be observed. In addition, by removing the cover plate, the operation platform can be maintained, repaired, and other special situations can be handled.

[0042] When the above operation platform is working, it is arranged downstream of the spiral mesh networking machine. Multiple spiral mesh sheets produced by the spiral mesh networking machine are spread on the spreading platform 1. The operator sits on the movable station 2, overlaps the edge parts of two spiral mesh sheets, and introduces the wire 23 into the overlapping wire loops 25. The automatic wire guiding mechanism 6 transports the wire forward. Once the operator makes an operational error, it can be discovered manually and the automatic wire guiding mechanism 6 can be operated through the control module to retract the wire slightly and then feed the wire again to correct it in time; after wire threading, the spiral mesh is wound downstream, and the wire threading situation can be further detected by the detection mechanism and an alarm can be given. At this time, the spiral mesh can be unwound through the clamping and conveying mechanism and the winding mechanism, causing the wire threading position 25 to return to the automatic wire guiding mechanism for re-wire threading. The operator can manipulate the movable station 2 to slide along the wire threading direction (Y direction) through the operation handle 9, reducing the walking distance and labor intensity.

[0043] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
