Description

Technical Field

[0001] The invention belongs to the technical field of laying mechanisms, and in particular relates to an automatic fiber axial shearing laying mechanism. Background Art

[0002] Fiber-wound FRP pipes are based on thermosetting polyester resin and glass fiber as reinforcing material. During the production process of FRP pipes, there are many ways to combine glass fiber and FRP pipes, including winding method, which mainly winds the glass fiber vertically around the FRP pipe, and laying method. One laying method is to lay the fiber cloth along the axial direction of the FRP pipe, but the fiber cloth is expensive, the production cost is high, and the laying speed is slow and the effectiveness is low. Another laying method is to directly cut a fiber into sections and automatically drop it down and lay it on the rotating FRP pipe. Although the existing equipment has improved the speed, when the existing equipment cuts the glass fiber, the cut fibers fall on the wound FRP in a disorderly manner, resulting in insufficient support for the axial laying of the glass fiber on the FRP pipe, and the glass fiber cannot better fit the surface of the FRP pipe, resulting in unqualified product production. Summary of the Invention

[0003] Purpose of the invention: The purpose of the present invention is to provide an automatic fiber axial shearing and laying mechanism to achieve the maximum degree of parallelism between the sheared fiberglass and the axial direction, so as to solve the technical problem that the existing equipment cannot lay the sheared glass fibers better because of the disordered shearing.

[0004] The automatic fiber axial shearing and laying mechanism includes a frame, characterized in that: a bearing seat 1 and a bearing seat 2 are sequentially provided on the frame from left to right, a bearing seat 1 is provided on the bearing seat 1, a driving shaft is provided in the bearing 1, a bearing seat 2 is provided on the bearing seat 2, a driven shaft is provided in the bearing 2, a front and rear opposite set of sprockets are provided on the driving shaft and the driven shaft, a left and right opposite set of sprockets are both provided with ear chains, an ear chain accessory block is provided on the ear chain, the motor drives the driving shaft to rotate clockwise in the bearing 1, the driving shaft drives the two sprockets on the driving shaft to rotate, and under the drive of the two parallel ear chains, the driven shaft and the two sprockets on the driven shaft rotate, and the driven shaft rotates in the bearing seat 2, and further includes;

[0005] A linear guide rail is axially fixed to the ear chain accessory block. The linear guide rails are parallel to each other. The ear chain accessory rotates with the rotation of the ear chain, and the linear guide rail rotates with the rotation of the ear chain accessory block.

[0006] A slider is provided on the linear guide rail, and a slider accessory is provided on the slider, and the slider slides back and forth on the linear guide rail;

[0007] A fiber push rod blocking block is provided on the frame, which cooperates with the shearing mechanism to cut the fiber and simultaneously compress and fix the fiber;

[0008] Cam track: The frame is provided with a cam track, which is located outside the driving shaft and the driven shaft and inside the linear guide rail. The left part of the cam track is parallel and the right part is U-shaped. Through the shape design of the cam track, the fiber is driven by the offset fiber push rods to be pulled from the initial straight line to S shape, and finally to a regular N shape that is parallel to the axis to the maximum extent, and then is sheared and laid on the fiberglass reinforced plastic pipe;

[0009] The shearing mechanism is provided on the slider accessory, and the shearing mechanism is arranged in a relatively staggered manner front and back on the slider accessory, and cooperates with the irregular movement on the cam track so that the fiber is pulled into an S shape. The shearing mechanism includes a fiber push rod and scissors. The slider accessory is provided with a fiber push rod, and scissors are provided in the fiber push rod. A pressure block is provided at the end of the scissors, and a torsion spring is provided on the scissors. The shaft on the torsion spring and the shaft on the scissors are both fixed inside the fiber push rod, thereby fixing the scissors in the fiber push rod, and the pressure block is connected to one end of the torsion spring. A spring rod is provided on the fiber push rod, and a fiber rod reset spring is provided in the spring rod. One end of a fiber pressure rod is provided in the spring rod, and the fiber pressure rod is connected to the fiber rod reset spring. A fiber pressure rod blocking block is provided on the fiber pressure rod. The fiber pressure rod is also provided with a clamping nut. When the fiber pressure rod blocking block contacts the arc-shaped port of the fiber push rod blocking block, the fiber pressure rod blocking block is subjected to a downward pressure force, which compresses the fiber rod reset spring and gradually presses the fiber pressure rod into the spring rod. At this time, the clamping nut also moves downward, pressing the fiber to the bottom of the opening, so that the fiber is compressed. The slider accessory is also provided with a threaded rod, and the end of the threaded rod is provided with an externally threaded bearing. The inner ring of the externally threaded bearing is threadedly connected to the end of the threaded rod. The cam track is provided with an externally threaded bearing, and the outer ring of the externally threaded bearing rotates in the cam track, so that the slider moves back and forth on the linear guide rail. Fiber is provided between the offset fiber push rods, and the fiber is located on the lower side of the frame. The fiber always moves on the lower side of the frame and is sheared.

[0010] Preferably, the contact port between the fiber push rod blocking block and the fiber pressure rod blocking block is arc-shaped, and the contact surface with the pressure block is sloped, so that when the fiber pressure rod blocking block contacts the arc-shaped port and the pressure block contacts the sloped contact surface, it is gradually pressed down and then moves horizontally.

[0011] Preferably, an opening is provided at the end of the fiber push rod, and fibers are arranged in the opening so that the fibers are restricted in the opening to prevent dislocation of the fibers.

[0012] Preferably, four groups of staggered and opposite fiber pushers are provided in the fiber pusher blocking block.

[0013] Preferably, a fixed tensioning plate is provided on the frame to fine-tune the center distance of the mechanism.

[0014] Compared with the prior art, the present invention has the following advantages: the two parallel ear chains are driven by the driving shaft, the driven shaft and the sprocket to rotate clockwise, so that the parallel linear guide rails also rotate synchronously. The left part of the cam track is parallel and the right part is U-shaped. The slider is on the linear guide rail, and the external threaded bearing rotates and moves in the cam track, so that the fiber push rod can move back and forth while moving to the left. The fiber push rods that are relatively staggered and arranged pull the fiber to the left, and at the same time, the fiber is pulled from the initial straight line into an S shape, and then pulled into an N shape that is as parallel to the axial direction as possible and cut by scissors. Then, it automatically falls and is laid on the rotating glass fiber reinforced plastic pipe along the axial direction, solving the technical problem that the existing equipment cannot lay the sheared glass fiber better because of the disorder.

[0015] The contact port between the fiber push rod blocking block and the fiber pressure rod blocking block is arc-shaped, the contact surface with the pressure block is sloped, and the end of the fiber push rod is provided with an opening. When the fiber push rod moves to pull and stretch the fiber into the maximum possible parallel state, the fiber pressure rod blocking block can also drive the fiber pressure rod to press down, so that the clamping nut moves downward, and the fiber is pressed and fixed at the bottom of the opening. At the same time, the downward pressure of the pressure block drives the torsion spring downward, so that the front and rear ends of the fiber are cut off by the corresponding scissors. At the same time, the fiber is in the opening and is limited by the opening to prevent the fiber from dislocation.

[0016] The fiber push rod blocking block is equipped with 4 sets of offset fiber push rods, so that after the front section of the fiber is cut, the rear section is immediately pressed and fixed, realizing continuous and uninterrupted shearing of the fiber. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Preferably, a fixed tensioning plate 29 is provided on the frame 1 .

[0042] Preferably, four groups of staggered and opposite fiber pushers 16 are provided in the fiber pusher blocking block 14 .

[0043] The method of use of the present invention is as follows:

[0044] Initial stage: The worker pulls one end of the fiber 27 on the fiber winding roller, passes through the center of the opening 28 of the fiber push rods 16 at the bottom of the frame 1, and presses against the fiber pressure rod 22 to pull. The motor drives the driving shaft 5 to rotate clockwise in the bearing 1 4, and the front and rear sprockets 8 on the driving shaft 5 rotate synchronously. The two parallel ear chains 9 provided on the sprockets 8 opposite to the left and right on the driving shaft 5 and the driven shaft 7 also rotate, causing the driven shaft 7 to rotate in the bearing 2 6. The linear guide 11 rotates synchronously, driving the slider 12 to rotate synchronously. Synchronously, the outer ring of the external threaded bearing 26 rotates and moves simultaneously in the cam track 15, causing the slider 12 to slide back and forth on the linear guide 11, causing the fiber push rods 16 at the bottom of the frame 1 that are offset from each other to move horizontally from right to left in a curved shape. When the first group of front and rear offset fiber push rods 16 enters the fiber push rod blocking block 14, the upper part of the fiber pressure rod blocking block 23 contacts the circular fiber push rod blocking block 14 The bottom of the arc-shaped port causes the fiber pressure rod blocking block 23 to drive the fiber pressure rod 22 to press down deep into the spring rod 20, the fiber rod return spring 21 is compressed, and the clamping nut 24 moves downward, so that the fiber 27 is clamped and fixed between the clamping nut 24 and the opening 28. After the fiber pressure rod blocking block 23 rests on the upper part of the fiber push rod blocking block 14 and runs a short distance, the pressing block 18 contacts the sloped contact surface of the fiber push rod blocking block 14, the pressing block 18 is pressed downward, the torsion spring 19 is compressed, and the fiber 27 is fixed between the clamping nut 24 and the opening 28. 7 The front and rear ends are cut by the corresponding scissors 17, and before the front fiber 27 is cut, the rear fiber 27 has been compressed and fixed by the clamping nut 24 of the rear group. When the scissors 17 on the first group of fiber push rods 16 cut the fiber 27, the rear fiber 27 is compressed and fixed by the clamping nut 24 and is also pulled by the fiber push rod 16. The worker can let go and stop pulling the fiber 27. This stage is very short, and the subsequent operation relies on the power of the mechanism to automatically cut, compress and pull.

[0045] Mechanism power operation: After the worker loosens the fiber 27, the fiber push rods 16 at the bottom of the frame 1, which are offset from each other, move horizontally from right to left in a curved shape. The fiber 27 is limited and pulled in the opening 28, first in an S shape, then in an N shape when it reaches the left, and gradually enters the fiber push rod blocking block 14. At this time, the working steps of cutting, pressing and fixing the fiber 27 are the same as the initial stage, except that human assistance in pulling is no longer required. The cut fiber 27 falls axially and is laid on the rotating fiberglass pipe, and the fiber rod reset spring 21 and torsion spring 19 automatically reset after the fiber push rod 16 leaves the fiber push rod blocking block 14.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
