Description

Technical Field

[0001] The present application relates to the technical field of carbon fiber product production and manufacturing, and in particular to an outer film stripping device for carbon fiber tube production. Background Art

[0002] Carbon fiber tube, also known as carbon fiber tube, also known as carbon tube, carbon fiber tube, is made of carbon fiber composite material pre-impregnated with styrene-based polyester resin and then heated, cured and pultruded (wound).

[0003] During the production process, various profiles can be produced through different molds, such as: carbon fiber round tubes of different specifications, square tubes of different specifications, sheets of different specifications, and other profiles. During the production of carbon fiber tubes, the prepreg needs to be rolled on the core rod using a pressing plate, and then a layer of heat shrink tape is wrapped on the outer wall of the prepreg, and then the whole is placed in an oven for curing and forming, and then the cured material is taken out, and the carbon fiber tube is formed. Then the heat shrink tape on the carbon fiber tube needs to be peeled off, and then the core rod can be pulled out from the middle of the carbon fiber tube.

[0004] The applicant believes that it is troublesome to manually peel off the heat shrink tape wound around the carbon fiber tube. Summary of the invention

[0005] The purpose of this application is to address the above-mentioned problems existing in the prior art and to propose an outer film stripping device for carbon fiber tube production.

[0006] The present application can be implemented through the following technical scheme: an outer film stripping device for carbon fiber tube production, comprising a frame, a receiving tank installed on the frame and open at both ends and the upper end, a winding roller, and a winding motor for driving the winding roller to rotate, the receiving tank is used to accommodate materials, and the side wall of the receiving tank is provided with a slot for the strip to pass through.

[0007] In the above technical scheme, when the heat shrink tape wound on the carbon fiber tube is peeled off, the material is placed in the receiving groove. The material is the carbon fiber tube wrapped with the heat shrink tape, and the tape is the heat shrink tape. One end of the tape is passed through the slot and then fixed on the winding roller. The winding motor is started to rotate the winding roller to wind the tape. During the winding process of the tape, the side wall of the receiving groove can limit the tape to prevent the tape from escaping from the receiving groove.

[0008] Further, it further includes a fixing frame, on which there is a clip for clamping the strip. The clip includes a mounting plate, a contact plate integrally formed with the mounting plate, and an abutting plate capable of contacting the contact plate. The contact plate and the abutting plate are respectively installed at two longitudinal sides of the mounting plate. The width of the abutting plate is smaller than that of the contact plate. There is a moving component on the machine frame. The winding roller is located below the accommodating groove. The moving component can drive the fixing frame to slide vertically so that the strip clamped by the clip contacts the winding roller. An opening component for separating the contact plate from the abutting plate is installed on the mounting plate.

[0009] In the above technical solution, in some settings, the winding roller is usually arranged below the accommodating groove, and the staff needs to bend down frequently to fix the strip on the winding roller, which is rather inconvenient. Moreover, it will be more tiring for those who already have lumbar diseases. When the clip is at the notch, first clamp one end of the strip with the clip, then apply glue to the strip, use the moving component to drive the clip to move downwards so that the clip moves close to the winding roller until the strip clamped by the clip contacts the winding roller, and then use the opening component to open the clip to release the strip. In this process, the staff does not need to bend down.

[0010] Further, the opening component includes a rotating rod passing through the mounting plate, a fixing plate formed on the rotating rod, and a rod motor for driving the rotating rod to rotate. The rotation of the fixing plate can make the contact plate contact or separate from the abutting plate.

[0011] In the above technical solution, the rod motor rotates the fixing plate through the rotating rod so that the fixing plate can contact the abutting plate and the mounting plate to make the abutting plate separate from the mounting plate, so that the staff does not need to manually open the clip to release the strip.

[0012] Further, there is also a driving component on the machine frame, which is used to drive a glue application device to approach or move away from the clip. The glue application device can apply glue to the strip.

[0013] In the above technical solution, the driving device can drive the glue application device to approach the clip so that the strip clamped by the clip is coated with glue, so that when the strip contacts the winding roller, the strip can be fixed on the winding roller through the glue, and the staff does not need to manually fix the strip on the winding roller.

[0014] Further, the driving component includes a rotating gear rotatably installed on the machine frame, an upper rack and a lower rack meshing with the rotating gear. There is a lower inclined surface formed on the fixing frame. The glue application device is installed on the lower rack. The lower inclined surface can contact the upper rack so that the glue application device can contact the strip clamped by the clip. There is also a torsion spring on the machine frame to force the rotating gear to rotate so that the lower rack moves away from the clip.

[0015] In the above technical solution, when the lower inclined surface contacts the upper rack, the upper rack can drive the lower rack to approach the fixed frame and horizontally slide by rotating the gear, so that the upper glue roller contacts the surface of the strip. At this time, glue can adhere to the surface of the strip. Then, the fixed frame leaves the upper rack, and the moving component drives the fixed frame to continue to move downward until the strip contacts the winding roller, so that the strip can be adhered to the winding roller through the glue. When the lower inclined surface disengages from the upper rack, the rotating gear can reverse under the action of the torsion spring, so that the upper glue roller moves away from the strip.

[0016] Further, an upper inclined surface is also formed on the fixed frame. The upper inclined surface is located above the lower inclined surface. One end of the upper inclined surface and the lower inclined surface close to each other is close to the rotating gear. The upper inclined surface can contact the upper rack to make the upper rack horizontally slide away from the clip.

[0017] In the above technical solution, after the strip is fixed on the winding roller through the glue, the moving component is used to drive the fixed frame to move vertically upward. When the upper inclined surface contacts the upper rack, the upper rack can horizontally slide away from the fixed frame to make way for the vertical movement of the fixed frame, so that the fixed frame can smoothly move upward above the upper rack and close to the position of the notch.

[0018] Further, the glue coating device includes a glue container disk installed on the lower rack, an upper glue roller, and a rotating motor for driving the upper glue roller to rotate. The glue container disk is used to hold glue. The upper glue roller can contact the glue in the glue container groove, and the upper glue roller can contact the strip clamped by the clip.

[0019] In the above technical solution, the rotating motor drives the upper glue roller to rotate, so that the surface of the upper glue roller can continuously adhere to glue.

[0020] Further, a heater capable of heating the glue is provided at the bottom of the glue container disk.

[0021] In the above technical solution, the heater can heat the glue in the glue container disk so that the glue is not easy to solidify.

[0022] Further, the accommodating groove is inclined.

[0023] In the above technical solution, the accommodating groove is inclined so that the heat shrinkable tape on the carbon fiber tube can directly slide down and leave the accommodating groove after being peeled off.

[0024] Further, a sliding groove is formed along the length direction of the bottom of the accommodating groove. The sliding groove is slidably connected with a sliding block. The sliding block can contact the material in the accommodating groove. A return spring for forcing the sliding block to approach the end of the accommodating groove away from the ground is provided below the accommodating groove.

[0025] In the above technical solution, after the heat shrink tape on the carbon fiber tube is peeled off, it can drive the sliding block to slide down during the sliding process, so that the surface of the carbon fiber tube is not easily worn during the sliding process. By setting a return spring, the return spring can drive the sliding block to return to the end of the accommodating groove away from the ground after the carbon fiber tube is separated from the sliding block.

[0026] To summarize, the present application has the following technical effects: the material is placed in the receiving groove, the material is a carbon fiber tube wrapped with a heat shrink tape, the tape is the heat shrink tape, one end of the tape is passed through the slot and then fixed on the winding roller, the winding motor is started to rotate the winding roller to wind the tape, and during the winding process of the tape, the side wall of the receiving groove can limit the tape to prevent the tape from leaving the receiving groove.
