Description

Technical Field

[0001] The utility model relates to the technical field of composite material processing, and more specifically to a winding device. Background Art

[0002] Continuous fiber reinforced thermoplastic prepreg tape is a composite material that uses continuous fiber as reinforcement and thermoplastic resin PP, PE, etc. as the matrix. PP, PE and glass fiber yarn are effectively combined through the hot runner, and it has high toughness and a tensile strength of about 900mpa.

[0003] In order to ensure good stability of the coiled material, prevent deformation of the material and dimensional accuracy, the coiling of this strip material currently mainly uses a constant tension coiler. At the beginning of the coiling operation, the staff manually fits the starting edge of the strip material to the coil core, and then rotates the coil core through a transmission device such as a motor chain, so that the strip material is wound around the coil core.

[0004] During the strip winding process, if workers do not operate in a standardized manner, there is a risk of limbs being caught in the process. Since the tensile strength of the strip is very high, limb injuries will inevitably occur if the strip is caught in the process, so safety protection devices need to be installed.

[0005] The existing safety protection device is fixed, and there is a problem with the installation distance between the safety protection device and the winding core. If the distance is too far, the initial winding gap is too large and there is still a safety hazard. If the distance is too close, the winding radius will be limited, thereby limiting the winding efficiency of the strip. Utility Model Content

[0047] Unless otherwise specified, the numerical ranges in this article include not only the entire range within its two endpoints, but also several sub-ranges included therein.

[0048] Figures 1 to 4A winding device according to the present utility model is shown. The winding device includes a frame 100, a core 120, a distance detection sensor 130, and a safety protection component 140. The core 120 is arranged on the frame 100 and is used for winding a strip 110. The distance detection sensor 130 is arranged on the frame 100 and is disposed on one side of the core 120 for sensing the outer position of the strip 110 wound on the core 120. The safety protection component 140 is arranged on the frame 100 and is spaced apart from the core 120 to form a safety detection gap 144 with the strip 110 on the core 120. A linear driving member 150 is connected to the safety protection component 140 for driving the safety protection component 140 and adjusting the position of the safety protection component 140 relative to the core 120 according to the sensing signal of the distance detection sensor 130.

[0049] In the winding device according to the present utility model, the distance detection sensor 130 detects the outer position of the strip 110 wound on the core 120, so as to judge the radius of the strip 110 wound on the core 120, enabling the linear driving member 150 to adjust the position of the safety protection component 140, so that the safety protection component 140 maintains a safety detection gap 144 with the outer side of the strip 110 wound on the core 120. This can not only maintain the protection function of the safety protection component 140, but also ensure the winding radius of the strip 110, thereby ensuring the winding efficiency of the winding device.

[0050] Optionally, referring to Figure 1 , a first bearing 101 and a chuck 103 are arranged on the frame 100. The first end of the core 120 is connected to the first bearing 101, and the second end of the core 120 is connected to the chuck 103, thereby realizing the detachable installation between the core 120 and the frame 100, facilitating the staff to remove the wound strip 110 from the core 120.

[0051] Optionally, in combination with Figure 2As shown in the figure, the rewinding device further includes a controller 170, which is electrically connected to the distance detection sensor 130 and the linear drive member 150 respectively. The controller 170 is configured to drive the linear drive member 150 according to the sensing signal of the distance detection sensor 130, so as to adjust the position of the safety protection component 140 relative to the core 120. Specifically, when the radius of the strip 110 wound on the core 120 gradually increases, the distance detection sensor 130 detects that the distance outside the strip 110 on the core 120 becomes smaller and sends the sensing signal to the controller 170. The controller 170 judges the distance (safety detection gap 144) between the safety protection component 140 and the outside of the strip 110 on the core 120 according to the sensing signal of the distance detection sensor 130, and thus sends a driving signal to the linear drive member 150. The linear drive member 150 drives the safety protection component 140, so that a certain safety detection gap 144 is maintained between the safety protection component 140 and the strip 110.

[0052] Optionally, on the basis of not affecting the detection and protection function of the safety protection component 140 and ensuring the rewinding efficiency of the rewinding device, the safety detection gap 144 between the safety protection component 140 and the strip 110 on the core 120 can vary within a certain range or can be kept consistent under the control of the controller 170, subject to the actual production requirements of the strip production line.

[0053] Optionally, referring to Figure 2 and Figure 3 , the safety protection component 140 is arranged below the core 120, and the linear drive member 150 is arranged below the safety protection component 140, which can prevent the safety protection component 140 from being interfered and enhance the stability of the rewinding device.

[0054] Optionally, the linear drive member 150 can be an electric push rod, a linear motor, a hydraulic cylinder or a cylinder, which can realize the linear drive adjustment of the safety protection component 140, and all should be within the protection scope of the present invention.

[0055] Optionally, the rewinding device includes a rotary drive member (not shown in the figure), which can be a servo motor. The rotary drive member is disposed on the frame 100 and connected to the end of the core 120. The controller 170 is electrically connected to the safety protection component 140 and the rotary drive member respectively. The controller 170 is configured to: control the rotary drive member to stop according to the safety trigger signal of the safety protection component 140. When a worker or foreign object is caught in the strip 110 on the core 120, the safety protection component 140 is triggered, and the safety trigger signal of the safety protection component 140 is sent to the controller 170, and the controller 170 controls the rotary drive member to stop, thereby preventing safety accidents and improving the safety of the rewinding device. Further, the controller 170 can also be electrically connected to the drive device of the strip 110 production line where the rewinding device is located. When the controller 170 receives the safety trigger signal, it can also control the strip 110 production line to stop, further ensuring safety.

[0056] Optionally, the frame 100 is further provided with a protective cover 104. The protective cover 104 is disposed at one end of the core 120 close to the rotary drive member, and the rotary drive member is disposed inside the protective cover 104, thereby protecting the rotary drive member and preventing safety accidents caused by accidental contact by workers.

[0057] Optionally, the rewinding device further includes a tension detection roller 180 and a pressure sensor. The frame 100 is further provided with a second bearing 102. The tension detection roller 180 is rotatably mounted on the frame 100 through the second bearing 102. The tension detection roller 180 is spaced apart from the core 120 along the horizontal direction D1. As Figure 1 shown, the strip 110 passes through the tension detection roller 180 and extends to the core 120. The pressure sensor is disposed between the tension detection roller 180 and the frame 100 and is used to sense the pressure received by the tension detection roller 180. The controller 170 is electrically connected to the pressure sensor. The controller 170 is configured to: judge the tension of the strip 110 according to the pressure signal of the pressure sensor and control the torque of the rotary drive member to remain constant, so that the force on the strip 110 during the rewinding process is stable, the strip 110 can be prevented from being damaged, and the quality of the strip 110 is guaranteed.

[0058] Further, the safety protection component 140 includes a base 141, a detection plate 142, and a deflection rate detection sensor 143. The base 141 is connected to the linear drive member 150, so that the linear drive member 150 can adjust the position of the safety protection component 140 relative to the core 120. The detection plate 142 is movably connected to the base 141 and spaced apart from the core 120 to form a safety detection gap 144 with the strip 110 on the core 120. The deflection rate detection sensor 143 is disposed on the base 141 for sensing the deflection rate of the detection plate 142, thereby determining whether a foreign object is caught on the core 120. When a human body or a foreign object is caught in the safety detection gap 144, the detection plate 142 is deflected by the touch of the human body or the foreign object, and the deflection rate detection sensor 143 senses the deflection rate of the detection plate 142 and issues a safety trigger signal. Furthermore, the controller 170 can control the rotation drive member to stop, preventing a safety accident from occurring.

[0059] Optionally, the detection plate 142 can be connected to the base 141 through a connecting member 145 (such as a mechanical contact or a hinge, etc.), so that the detection plate 142 is movably connected to the base 141 and the transmission is stable.

[0060] Further, the detection plate 142 is pivotally connected to the base 141 between the initial position and the trigger position. The initial position of the detection plate 142 can be selected to be parallel to the vertical direction D2, and the trigger position of the detection plate 142 can be an angle formed by deviating from the vertical direction D2. The deflection rate detection sensor 143 is configured to sense the detection plate 142 deviating from the initial position and generate a safety trigger signal. If the detection plate 142 is touched by a human body or a foreign object, the detection plate 142 can deviate from the initial position, so that the deflection rate detection sensor 143 senses and generates a safety trigger signal.

[0061] Optionally, the safety protection component 140 further includes an elastic reset element (not shown in the figure). The elastic reset element can be selected as a torsion spring. The elastic reset element is respectively connected to the detection plate 142 and the base 141, and the elastic reset element is configured to have a force towards the initial position on the detection plate 142 deviating from the initial position, so that the detection plate 142 can be kept in the initial position when the detection plate 142 is not subject to external force, preventing the safety protection component 140 from false alarming.

[0062] Optionally, referring to Figure 3 , the winding device further includes a sliding mechanism 160. The sliding mechanism 160 includes a first sliding part 161 and a second sliding part 162. The first sliding part 161 is disposed on the frame 100, the second sliding part 162 is disposed on the base 141, and the second sliding part 162 is slidably connected to the first sliding part 161, so that the safety protection component 140 can stably slide relative to the frame 100, preventing the safety protection component 140 from skewing and improving the detection accuracy of the safety protection component 140.

[0063] Further, one of the first sliding portion 161 and the second sliding portion 162 is configured as a slider, and the other of the first sliding portion 161 and the second sliding portion 162 is configured as a slideway. Specifically, the first sliding portion 161 is configured as a slider, and the second sliding portion 162 is configured as a slideway. The second sliding portion 162 is disposed through the first sliding portion 161, so that the base 141 can move relative to the frame 100 along the extending direction of the second sliding portion 162, and the transmission is stable.
