DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0025] like Figures 1 to 8 As shown, a tension-controlled automatic lining device comprises a base 1 and a support frame, wherein a rotating shaft 2 is provided at the bottom of the support frame, and the rotating shaft 2 is vertically inserted into the base 1 .

[0026] A tension-controlled automatic lining making device of this embodiment has a structural setting in which its support frame is connected to the base 1 through a rotating shaft 2, so that the support frame can rotate. When in use, the lining cloth is set on the support frame. The rotation of the support frame can realize the control of the tension of the lining cloth. The control of the tension force includes the control of the strength and direction, so as to effectively improve the uniformity of the lining cloth winding.

[0027] Specifically, the support frame includes a bracket and a cloth drum 3, the bracket includes a base plate 4, a first support rod 5, a second support rod 6 and a fixing assembly, the first support rod 5 and the second support rod 6 are vertically arranged on the base plate 4, the fixing assembly includes a first fixing block 11, a second fixing block 12 and a fixing screw 13, the fixing screw 13 passes through the first fixing block 11 and the second fixing block 12, the fixing screw 13 is fixedly connected to the first fixing block 11, the second fixing block 12 is provided with a fixing screw hole, the fixing screw hole cooperates with the fixing screw 13, the two ends of the fixing screw 13 are respectively laid on the first support rod 5 and the second support rod 6, and the cloth drum 3 is clamped by the first fixing block 11 and the second fixing block 12. The fixing assembly is configured to be detachable. When the cloth tube 3 needs to be replaced, the second fixing block 12 is rotated to release the cooperation between the fixing screw hole and the fixing screw 13, that is, the second fixing block 12 is removed from the fixing screw 13. At this time, the clamped state of the cloth tube 3 is released, and the cloth tube 3 can be removed and replaced with a new cloth tube 3. After the new cloth tube 3 is replaced in place, the second fixing block 12 is matched with the fixing screw 13 again, so that the first fixing block 11 and the second fixing block 12 clamp the new cloth tube 3, thereby realizing convenient replacement of the cloth tube 3. At the same time, since the cloth tube 3 is fixed in a clamped state, the cloth tube 3 cannot slide along the rotating shaft 2 as in the prior art, thereby realizing its stable fixation, which is conducive to improving the quality of the lining.

[0028] In order to adapt to the fixing of cloth tubes 3 of different diameters, the first fixing block 11 and the second fixing block 12 are both set to be conical or truncated cone. By setting the first fixing block 11 and the second fixing block 12 to be conical or truncated cone, it can be suitable for fixing cloth tubes 3 of different diameters. Under the above structural setting, cloth tubes 3 of a certain range of diameters can be stably fixed by the first fixing block 11 and the second fixing block 12.

[0029] In order to facilitate the rotation of the second fixed block 12 , a plurality of levers 14 are provided on the second fixed block 12 . The plurality of levers 14 are radially distributed with the second fixed block 12 as the center. When the second fixed block 12 needs to be rotated, it is achieved by moving the levers 14 .

[0030] Further, the support frame also includes a fixing nut 15 and a fixing sleeve 16, the fixing nut 15 cooperates with the fixing screw 13 and presses against the side wall of the first support rod 5, the inner wall of the fixing sleeve 16 is provided with a thread that cooperates with the fixing screw 13, one end of the fixing sleeve 16 presses against the side wall of the second support rod 6, the fixing sleeve 16 is provided with an indication mark 17, the side wall of the second support rod 6 is provided with a plurality of marks 7 that cooperate with the indication mark 17, the plurality of marks 7 are evenly distributed around the fixing screw 13, the side wall of the second support rod 6 is provided with a receiving hole 8, the receiving hole 8 is provided with a connecting spring 9 and an indicating block 10, the indicating block 10 extends out of the receiving hole 8, the side wall of the indicating block 10 has a plurality of color segments, and the end of the indicating block 10 presses against the end of the sleeve. Through the above structural arrangement, through the cooperation of the fixing nut 15 and the fixing sleeve 16, the adjustment of the resistance during the rotation of the fixing screw 13 can be effectively achieved. Specifically, when the resistance between the fixing sleeve 16 and the side wall of the second support rod 6 is large, the fixing screw 13 is difficult to rotate and the lining cloth tension is large. When the resistance between the fixing sleeve 16 and the side wall of the second support rod 6 is small, the fixing screw 13 is easy to rotate and the lining cloth is subjected to small tension. At the same time, in order to accurately control the magnitude of the lining cloth tension, a plurality of marks 7 are provided on the side wall of the second support rod 6, and an indication mark 17 is provided on the side wall of the fixing sleeve 16. The magnitude of the resistance between the fixing sleeve 16 and the side wall of the second support rod 6 is judged by indicating different marks 7 by the indication mark 17. Furthermore, when the fixed sleeve 16 is in contact with the side wall of the second support rod 6, its indicator mark 17 also points to a certain mark 7, but the indication at this time is wrong. Only when the fixed sleeve 16 moves to contact the side wall of the second support rod 6 can the mark 7 be used to indicate the magnitude of the pressing force between the fixed sleeve 16 and the side wall of the second support rod 6. As for how to judge whether the fixed sleeve 16 has contacted the side wall of the second support rod 6, it is done through the indication of the indicator block. When the indicator block 10 is pushed by the fixed sleeve 16 into the receiving space, and when all the color blocks on its side wall completely enter the receiving hole 8, it means that the fixed sleeve 16 is in contact with the side wall of the second support rod 6. At this time, the indication of the indicator mark 7 can be used as a basis for judgment.

[0031] Specifically, the support frame further includes a receiving groove 18, a tension frame 19, a first rotating shaft 20 and a second rotating shaft 21, the support frame is fixedly connected to the receiving groove 18, the rotating shaft 2 is arranged at the bottom of the receiving groove 18, the tension frame 19 is arranged in the receiving groove 18, the first rotating shaft 20 and the second rotating shaft 21 are arranged parallel to the length direction of the cloth cylinder 3, the first rotating shaft 20 is arranged above the second rotating shaft 21, and the cloth cylinder 3 and the second rotating shaft 21 are respectively located above both sides of the receiving groove 18. During operation, the lining cloth drawn from the cloth cylinder 3 is wound around the bottom of the tension frame 19, then passes between the first rotating shaft 20 and the second rotating shaft 21, and then is wound onto the core mold.

[0032] A tension-controlled automatic lining making device of the present embodiment also includes a speed indicating device, the speed indicating device includes an indicating tube and a pointer 34, the indicating tube includes a connecting block 22, a knob 24, an airbag 25, a connecting tube, a tube body 26, a slide rail 30, a slide seat 31, a squeezing bag 32 and a floating member 33, the connecting block 22 connects the bracket and the tube body 26, the connecting block 22 is provided with a placement hole 23, the side wall of the placement hole 23 is provided with a first thread, the knob 24 is provided with a second thread matching the first thread, the airbag 25 is arranged in the placement hole 23, is located at the bottom of the knob 24, and is connected to one end of the connecting tube, the other end of the connecting tube is connected to the squeezing bag 32, and the tube body 26 is set to be transparent The tube body 26 has a first bending portion 27 and a second bending portion 28 at both ends, respectively, the first bending portion and the second bending portion 28 are connected to the tube body 26 through a connecting sleeve 29, the slide rail 30 is arranged in the connecting sleeve 29, the squeezing bag 32 is arranged along the side wall of the slide rail 30, the slide seat 31 cooperates with the slide rail 30, the squeezing bag 32 is pressed against the wall surface of the slide seat 31, the floating member 33 is arranged on the slide seat 31, the first bending portion 27 and the second bending portion 28 have the same volume, the first bending portion 27 and the tube body 26, or the second bending portion and the tube body 26, are filled with water, one end of the pointer 34 is connected to the bracket, and the other end points to the tube body 26.

[0033] Under the above structural setting, the position of the floating member 33 can be used to indicate the rotation speed of the support frame, so that the staff can rotate the support frame at a uniform speed to achieve uniform winding of the lining cloth. Specifically, the first bending portion 27 and the second bending portion 28 can rotate around the end of the tube body 26. When the first bending degree bends upward and the second bending portion 28 bends downward, the water in the first bending portion 27 flows toward the second bending portion 28, thereby driving the floating member 33 to move. Similarly, when the first turning portion bends downward and the second turning portion bends upward, the water in the second bending portion 28 flows in the direction of the first bending degree. Since the water flow speed is relatively uniform, the movement speed of the floating member 33 is also relatively uniform. Therefore, by tracking the floating member 33 through the pointer 34, a relatively stable rotation process of the support frame can be achieved to prevent it from rotating too fast or too slow. , different speed control requirements can be achieved by controlling the interaction force between the squeezing bag 32 and the slide 31. When the knob 24 is turned, the airbag 25 can be compressed or released. When the airbag 25 is compressed, the gas in the airbag 25 enters the squeezing bag 32, causing the squeezing bag 32 to expand, and the interaction force between the squeezing bag 32 and the slide 31 becomes larger, thereby increasing the resistance encountered by the slide 31 during the movement, that is, the movement speed of the floating member 33 becomes smaller. When the airbag 25 is released, the gas in the squeezing bag 32 enters the airbag 25, the squeezing bag 32 contracts, and the interaction force between the squeezing bag 32 and the slide 31 becomes smaller, thereby reducing the resistance encountered by the slide 31 during the movement, that is, the movement speed of the floating member 33 becomes larger. Therefore, the movement speed of the floating member 33 can be controlled through the above structure.

[0034] In order to ensure sufficient flow time, a flow control valve is provided in the connecting sleeve 29, and the flow rate is controlled by the flow control valve, so that there is sufficient water flow time to ensure the completion of one-time lining.
