Technical Field

[0001] The utility model belongs to the technical field of coil processing, and particularly relates to a flexible coil transmission deviation correction device. Background Art

[0002] The waterproof coil is mainly used for building walls, roofs, tunnels, roads, landfills, etc., and is a flexible building material product that can be curled into a roll shape to resist external rainwater and groundwater seepage. As a leak-free connection between the engineering foundation and the building, it is the first barrier for the overall project waterproofing and plays a crucial role in the entire project. The waterproof coil is processed and formed through a series of processes such as covering the carcass with waterproof materials. Due to the long overall process, the carcass is prone to deviation during transmission, resulting in a decline in the quality of the waterproof coil and even damage to the waterproof coil.

[0003] Therefore, a flexible coil transmission deviation correction device is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flexible coil transmission deviation correction device, so as to overcome the defect that the carcass is prone to deviation during the existing coil processing, resulting in a decline in the quality of the waterproof coil and even damage to the waterproof coil. The specific technical solutions are as follows:

[0005] A flexible coil transmission deviation correction device includes a support frame, a support plate, a limit plate, a first lead screw, a first rotation handle, a first slider, an electric push rod, a deviation correction wheel, a detection unit, a brushless motor, and an auxiliary plate. The auxiliary plate is installed on the support frame. One end of two support plates is vertically and symmetrically installed on the support frame. The other ends of the support plates are respectively connected to both ends of the limit plate. Both ends of the first lead screw are rotatably installed on the support plate. The thread directions at both ends of the first lead screw are opposite. The first rotation handle is fixedly installed at one end of the first lead screw. Two first sliders are respectively rotatably installed at both ends of the first lead screw. The top of the first slider is in contact with the limit plate;

[0006] The fixed end of the electric push rod is vertically connected to the side of the first slider away from the limit plate. The deviation correction wheel is rotatably installed at the output end of the electric push rod. The brushless motor is built into the deviation correction wheel. The deviation correction wheel is located directly above the auxiliary plate. The projection line of the deviation correction wheel on the auxiliary plate forms an angle with the advancing direction of the material;

[0007] The detection unit is symmetrically installed on the auxiliary plate and is used to detect whether the material deviates. The detection unit is electrically connected to the electric push rod and the brushless motor.

[0008] Preferably, it further includes a control unit for controlling the brushless motor so that the component velocity of the outer surface line velocity of the deviation rectifying wheel in the forward direction of the material is equal to the feeding velocity of the material.

[0009] Preferably, an observation window is formed in the limiting plate, a transparent plate with scales is installed in the observation window, a positioning mark is arranged on one side of the first slider close to the limiting plate, the connection line between the positioning mark and the lowest point of the deviation rectifying wheel is perpendicular to the auxiliary plate, and the transparent plate does not contact the first slider.

[0010] Preferably, a gap is arranged between the auxiliary plate and the material so that they will not contact when the deviation rectifying wheel does not start.

[0011] Preferably, the detection unit is located between the limiting plate and the material discharging position.

[0012] Preferably, the detection unit includes a second lead screw, a second slider, a second rotating handle and a sensor. The second lead screw is rotatably installed on the support frame, the thread directions at both ends of the second lead screw are opposite, the two second sliders are respectively rotatably installed at both ends of the second lead screw, a guiding through hole is formed in the auxiliary plate, the guiding through hole is located above the second lead screw, one end of the sensor is installed on the second slider and the other end is located in the guiding through hole, and the second rotating handle is fixedly installed at one end of the second lead screw.

[0013] Preferably, the deviation rectifying wheel is cylindrical so that the circumferential surface of the deviation rectifying wheel is in line contact with the material.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model detects the position of the material through the sensor. When the material deviates, the electric push rod drives the deviation rectifying wheel to move towards the material, so that the deviation rectifying wheel squeezes the material with the auxiliary plate. At the same time, the brushless motor drives the deviation rectifying wheel to rotate. Since there is an included angle between the projection line of the deviation rectifying wheel on the auxiliary plate and the advancing direction of the material, the deviation rectifying wheel drives the material assembly to move horizontally through the inclined friction on the material until the material no longer deviates. The application adopts a step-by-step deviation rectifying method, which will not generate a large lateral force on the material, avoiding damage to the material and also avoiding the decline of the quality of the coil material.

[0016] 2. The utility model adjusts the positions of the deviation rectifying wheel and the detection unit by controlling the first lead screw and the second lead screw, so that the application can adapt to materials of different sizes and improve the practicability of the application.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment, refer to Figures 1 to 3 .

[0025] The auxiliary plate 9 is installed on the support frame 1 by bolts and is located between the first and second guiding rollers 16 behind the unwinding roller. One end of the two support plates 2 is vertically and symmetrically installed on the support frame 1 by bolts. The other ends of the support plates 2 are respectively connected to the two ends of the limit plate 3 by bolts. Both ends of the first lead screw 4 are rotatably installed on the support plates 2 through bearings. The thread directions at both ends of the first lead screw 4 are opposite. The first turning handle 5 is fixedly installed at one end of the first lead screw 4. The two first sliders 6 are respectively rotatably installed at both ends of the first lead screw 4. The top of the first slider 6 is in contact with the limit plate 3. Since the limit plate 3 restricts the rotation of the first slider 6, when the first turning handle 5 is rotated, the first sliders 6 will approach or move away from each other on the first lead screw 4, ensuring that the carcass 17 is always in the centered position when adjusting the carcass 17.

[0026] The fixed end of the electric push rod 7 is vertically connected to the side of the first slider 6 away from the limit plate 3 by bolts. The deviation correction wheel 8 is rotatably installed on the output end of the electric push rod 7. The brushless motor is built into the deviation correction wheel 8 and is used to drive the deviation correction wheel 8 to rotate. The deviation correction wheel 8 is located directly above the auxiliary plate 9. There is an angle between the projection line of the deviation correction wheel 8 on the auxiliary plate 9 and the advancing direction of the coil material. The deviation correction wheel 8 generates a frictional force on the carcass 17 through the auxiliary plate 9, and drives the carcass 17 to tilt and move in the reset direction through the frictional force. The tilted deviation correction wheel 8 can be decomposed into movements in the vertical and horizontal directions. The vertical direction is parallel to the advancing direction of the carcass 17, and the horizontal direction can drive the carcass 17 to move towards the centered position, gradually driving the carcass 17 to perform a reset movement. This avoids the quality decline of the coil material or damage to the carcass 17 caused by the deviation of the carcass 17.

[0027] The detection units are symmetrically installed on the auxiliary plate 9 and are used to detect whether the coil material is offset. The detection units are electrically connected to the electric push rod 7 and the brushless motor. When the detection units are triggered, the corresponding electric push rod 7 and brushless motor will be started. The electric push rod 7 drives the deviation correction wheel 8 to move towards the carcass 17, and the brushless motor drives the deviation correction wheel 8 to rotate. When the carcass 17 is corrected, the detection units will not be triggered. The detection units control the electric push rod 7 and the brushless motor to stop starting, and control the electric push rod 7 to return to the state of not contacting the carcass 17.

[0028] The control unit is used to control the brushless motor. Here, the control unit can be components such as a single-chip microcomputer or a computer. Before production, the staff can input the feeding speed of the carcass 17 into the control unit. The control unit calculates the rotation speed of the deviation correction wheel 8 so that the linear velocity of the outer surface of the deviation correction wheel 8 in the direction of the advancing direction of the coil material is equal to the feeding speed of the coil material, avoiding relative friction between the deviation correction wheel 8 and the carcass 17, which may cause damage to the carcass 17.

[0029] An observation window is opened on the limit plate 3. A transparent plate 10 with scales is installed in the observation window. A positioning mark is provided on the side of the first slider 6 close to the limit plate 3. The line connecting the positioning mark and the lowest point of the deviation correction wheel 8 is perpendicular to the auxiliary plate 9. The transparent plate 10 does not contact the first slider 6. This facilitates the staff to adjust the position of the first slider 6 through the first rotating handle 5 and improves work efficiency. At the same time, due to the characteristic of the double-threaded screw of the first lead screw 4, the carcass 17 can be centered and corrected, so that the carcass 17 is in a centered position, improving the processing quality of the coil material.

[0030] There is a gap between the auxiliary plate 9 and the coil material, so that they will not contact each other when the deviation correction wheel 8 is not activated, avoiding friction between the auxiliary plate 9 and the carcass 17 when deviation correction is not carried out, which affects the quality of the carcass 17. When the carcass 17 is offset, the degree of its offset will gradually increase. If it is not corrected in time, it will affect the subsequent processing of the carcass 17. The detection unit is located between the limit plate 3 and the coil material feeding place. The carcass 17 will encounter the detection unit first before passing through the deviation correction wheel 8. Therefore, when the carcass 17 starts to be offset, the electric push rod 7 and the brushless motor will start. It takes a certain amount of time for the offset carcass 17 to move to the deviation correction wheel 8. Therefore, the processed length of the offset carcass 17 can be reduced, improving the overall production quality of the coil material.

[0031] The second lead screw 11 is rotatably installed on the support frame 1. The thread directions at both ends of the second lead screw 11 are opposite, so that the second sliders 12 can approach or move away from each other simultaneously. The two second sliders 12 are respectively rotatably installed at both ends of the second lead screw 11. A guiding through hole 15 is formed on the auxiliary plate 9. The guiding through hole 15 is located above the second lead screw 11. One end of the sensor 14 is installed on the second slider 12, and the other end is located in the guiding through hole 15. The guiding through hole 15 restricts the rotation of the sensor 14 and the second slider 12, so that the two can only move along the axis direction of the second lead screw 11. The second rotating handle 13 is fixedly installed at one end of the second lead screw 11. The sensor 14 here can be an infrared sensor 14 or an acoustic wave sensor 14. When the carcass 17 covers above the sensor 14, the sensor 14 is triggered. The staff can adjust the position of the sensor 14 by rotating the second rotating handle 13, thereby restricting the offset range of the carcass 17, so that the present application can adapt to the processing of coil materials of different sizes.

[0032] When one side sensor 14 is triggered, the sensor 14 will activate the electric push rod 7 and the brushless motor close to the other side sensor 14, and pull the carcass 17 through the deviation correction wheel 8 on the other side for deviation correction. Compared with the method of adjusting by pushing the carcass 17, it can avoid wrinkles that may occur when the carcass 17 is corrected.

[0033] The deviation correction wheel 8 is cylindrical, so that the circumferential surface of the deviation correction wheel 8 is in line contact with the coil material, increasing the contact area between the deviation correction wheel 8 and the carcass 17, preventing slippage between the two, and ensuring the efficiency of deviation correction.

These descriptions are not intended to limit the present utility model to the precise forms disclosed, and obviously, many changes and variations can be made in accordance with the above teachings.
