Detailed Description

For the purposes of making the utility model more apparent, a length-quantifiable automatic web-laying device of the present utility model will be further described with reference to the accompanying drawings, wherein the specific embodiments described herein are for purposes of illustration only and are not intended to be limiting.

As shown in fig. 1, an automatic net separating device capable of measuring length comprises a frame 1 formed by splicing and welding profile steel, a rotatable unreeling roller 2, a geothermal net length measuring mechanism 100 and a driven rotating reeling roller 3 are sequentially arranged on the frame 1 from right to left, the geothermal net 900 to be separated is reeled on the unreeling roller 2, and the reeling roller 3 is used for reeling the geothermal net with measured length.

Referring to fig. 2 and 3, the geothermal net length metering mechanism 100 includes a first net passing roller 101 and a second net passing roller 102, two ends of the first net passing roller 101 are connected with bearing blocks 103, and the bearing blocks 103 are fixedly connected to the upper side of the frame 1. One end of the first screen drum 101 passes through the bearing seat 103 and is coaxially connected with the meter 105 through the coupler 104, and the meter 105 is connected to the outer side surface of the bearing seat 103 through the bracket 106 in a shape of a Chinese character 'ji'. Here, the meter 105 is a prior art, and an electronic meter encoder may be used, which is an electronic device that uses some electronic components to form an electronic device capable of realizing a length measurement function, and converts the electronic device into a corresponding length size according to the circumference of the first screen drum 101 by detecting the rotation number and the angle of the first screen drum 101. The two ends of the second net passing roller 102 are in clearance fit with the shaft and the holes to realize rotary connection with the frame 1. The first passing roller 101 is positioned above the second passing roller 102 in parallel, and is spaced apart from the second passing roller 102 in the horizontal direction, and the second passing roller 102 is closer to the unreeling roller 2 than the first passing roller 101. The geothermal net 900 is led out from the unreeling roller 2, is turned to the rear lower side from the upper surface of the first passing roller 101 by being closely attached to and wrapped around the lower surface thereof, is turned to the front side (reeling roller side) from the upper surface of the second passing roller 102 by being closely attached to and wrapped around the lower surface thereof, and is finally reeled onto the reeling roller 3. Due to the setting of the relative positions of the first and second passing drums, the geothermal network 900 has a larger contact area with the peripheral surface of the first passing drum 101, and the geothermal network 900 and the first passing drum 101 will not slip in the moving process, i.e. the first passing drum 101 and the geothermal network 900 contacting with each other move synchronously. Of course, other arrangements of the relative positions of the first and second passing drums may be adopted, based on the fact that the geothermal net 900 does not slip with the circumferential surface of the first passing drum 101.

In addition, in order to further increase the friction force between the first passing roller 101 and the geothermal net 900 in contact with the first passing roller 101, the surface of the first passing roller 101 is provided with an encapsulating layer 101a, and the encapsulating layer 101a may be made of a material with a high friction coefficient, such as rubber, polyurethane, and the like.

In some embodiments, a net pressing mechanism 200 is further disposed between the geothermal net length metering mechanism 100 and the winding drum 3, as shown in fig. 4, the net pressing mechanism 200 includes a cylinder 201 that stretches vertically downward, the cylinder 201 is fixedly connected to the gate frame beam 1a of the frame 1, a pressing plate 202 is connected to a stretching end of the cylinder 201, and a lower end face of the pressing plate 202 is a plane; the frame 1 is provided with a backing plate 203, the backing plate 203 is positioned right below the pressing plate 202, the upper surface of the backing plate 203 is parallel to the lower end surface of the pressing plate 202, and the length of the backing plate 203 is larger than the width of the geothermal net 900. When the telescopic end of the air cylinder 201 works to drive the pressing plate 202 to press down, the geothermal network 900 can be clamped between the pressing plate 202 and the backing plate 203, and the geothermal network 900 is cut by manpower. Here, the cylinder 201 is preferably a cylinder with a guide rod to improve stability of the pressing action.

Preferably, a third net passing roller 4 and a fourth net passing roller 5 are respectively arranged at two sides of the net pressing mechanism 200, and the third net passing roller and the fourth net passing roller are connected to the frame 1 through a clearance fit shaft and hole structure, so that free rotation of the rollers is realized. The geothermal net 900 sequentially passes through and is tightly attached to the upper peripheral surfaces of the third and fourth net passing rollers, the geothermal net is tightly stretched and positioned above the base plate 203, and the tightened geothermal net is tightly pressed by the net pressing mechanism 200, so that the geothermal net is more convenient to cut manually.

The rotatable connection between the unreeling roller 2 and the frame 1 has various structures, preferably the structures shown in fig. 5 and 6: a pair of unwinding roller bases 300 arranged coaxially are fixedly connected to the frame 1, each unwinding roller base 300 comprises a base 301, a V-shaped groove 302 is formed in the base 301, the V-shaped groove 302 is used as a groove type of a symmetrical center, two rollers 303 are respectively arranged on two sides of the base 301, the rollers 303 can freely rotate, the rotation axes of the rollers 303 are parallel to the axis of the unwinding roller 2, and part of the peripheral surface of each roller 303 is exposed out of a notch formed by the V-shaped groove 302. The two ends of the unreeling roller 2 are provided with overhanging shaft heads, when each end shaft head of the unreeling roller 2 is placed on the unreeling roller seat 300, the unreeling roller seat is just erected on the two rollers 303 to form stable two-point support, and when the geothermal net 900 is pulled by external force to move, the shaft heads of the unreeling roller 2 also rotate on the two rollers 303.

Since the shaft head of the unreeling roller 2 is only supported by the roller 303, the shaft head may jump during the rotation of the unreeling roller 2. For this purpose, one side of the base 301 is hinged to one end of the pressing cover 304 through a hinge structure with a shaft and a hole, and a lock catch 305 fastened to the other end of the pressing cover 304 is arranged on the other side of the base 301, wherein the lock catch 305 is a product purchased in the market. When the pressing cover 304 is buckled with the base 301, the pressing cover 304 presses on the shaft head of the unreeling roller 2 to prevent the shaft head from jumping. Of course, the bottom side of the gland 304 may also be provided with an arc surface 304a adapted to the shaft head of the unreeling roller 2, so as to increase the contact area and improve the rotation stability of the unreeling roller 2.

Further, a friction block 307 is connected to the base 301 through a locking groove 306, and the friction block 307 has an outer shape matching with the lower peripheral surface of the pair of rollers 303, and the friction block 307 contacts with the lower peripheral surface of the pair of rollers 303 to generate friction resistance, thereby preventing the rollers 303 from rotating and further preventing the unreeling roller 2 from rotating. Since the unreeling roller 2 with the geothermal net has a large mass, the inertial effect of the unreeling roller 2 during rotation is large, the frictional resistance can reduce the inertial effect of the rotation, and the unreeling roller 2 stops rotating instantly when the external tension applied to the geothermal net is cancelled. Here, the clamping groove 306 is a bent sheet metal part, and has an upward opening, the bottom of the clamping groove is screwed with a group of upward adjusting screws 308, and the adjusting screws 308 are pressed against the friction block 307 to adjust the extrusion acting force of the friction block 307 and the roller 303.

The driving shaft 7 also has a recess at one end thereof, which is adapted to and clearance-fitted with the shaft head of the winding drum 3, and a torque-transmitting connection, and of course, in order to prevent the power rotation from being affected by the clearance between the shaft head of the winding drum 3 and the recess, a locking screw 404 may be provided on the driving shaft 7 and the socket 402. The shaft body of the driving shaft 7 is connected with a pair of bearing 8 with a seat, the bearing with a seat is fixedly connected with the frame 1, and the other end of the driving shaft 7 is connected with the driving device 500.

Here, the driving device 500 may adopt a conventional structure such as a motor direct connection driving, and considering the device volume, performance requirements and cost, the driving device 500 adopts a motor+sprocket and chain transmission structure, that is, the driving device comprises a servo motor 501 located in the frame 1, an output end of the servo motor 501 is connected with a driving sprocket 502, one end of a driving shaft 7 is connected with a driven sprocket 504, and the driving sprocket and the driven sprocket are transmitted through a chain 503.
