Description

Technical Field

[0001] The utility model relates to the technical field of sand-filled pipe production, in particular to a yarn guide device for producing glass fiber reinforced plastic sand-filled pipes. Background Art

[0002] FRP products are widely used in chemical industry, environmental protection and other fields due to their long service life and resistance to chemical corrosion. At present, in the production of FRP sand-filled pipes, continuous fiber yarn bundles need to be evenly, stably and continuously pulled onto the rotating core mold. The existing yarn guide device is prone to loose fiber yarn bundles during the pulling process, resulting in displacement of the pulling position and poor stability. Patent documents have now been issued to improve this.

[0003] For example, Chinese patent CN218057945U, a yarn guiding device for producing glass fiber reinforced plastic sand-filled pipes, includes a base plate, a yarn guide plate, a connecting frame, a transition roller, a movable groove, a slot hole, a movable block, a fixed component, a motor and a rotating roller, the yarn guide plate is arranged at one end of the base plate, the connecting frame is arranged at the other end of the base plate, the transition roller is arranged on the inner wall of the connecting frame, the movable groove is symmetrically arranged on the inner wall of the connecting frame, the slot hole passes through the side wall of the connecting frame and is arranged in one group of movable grooves, the movable block is slidably arranged in the movable groove, the fixed component is arranged on the movable block, the motor passes through the slot hole and is arranged on one group of movable blocks, one end of the rotating roller is fixedly arranged on the output shaft end of the motor, and the other end of the rotating roller is arranged on another group of movable blocks through a bearing. The utility model belongs to the technical field of glass fiber reinforced plastic product processing, specifically refers to a yarn guiding device for producing glass fiber reinforced plastic sand-filled pipes with high stability, which can avoid the loose fiber yarn bundle causing the traction position to be offset.

[0004] Although the device in the above document can manually adjust the roller to adjust the tension of the yarn, it still has obvious defects in actual use, such as:

[0005] The existing yarn is continuous during the pulling process, without interruption and at a high speed. However, once the yarn becomes loose, it will take a long time for the staff to adjust the equipment, which will cause the loose yarn to be pulled too long and affect the quality of subsequent processing.

[0006] Therefore, a fiberglass reinforced plastic sand-filled pipe production guide device capable of quickly adjusting tension is designed to solve this type of defect. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a yarn guide device for producing glass fiber reinforced plastic sand-filled pipes, which solves the problems that the prior yarn guide devices are complicated to adjust and cannot be used quickly.

[0013] The utility model provides a yarn guide device for the production of glass fiber reinforced plastic sand-filled pipes. Compared with the existing technology, it has the following advantages:

[0014] (1) The fiberglass sand-filled pipe production yarn guide device is provided with two wire lifting rotating rods on the upper part of the protective box, and is connected by a vertical guide slide and an arc pressure seat, and is used with two first buttons and a second button. The arrangement of these structures can keep the yarn in a taut state during the yarn pulling process, and once loosening occurs, the arc pressure seat will press two different sets of first buttons and second buttons, thereby docking the conical seat with the conical frame to reduce the rotation speed of the loosening rotating rod, so that the loose yarn is quickly pulled to restore the taut state, and after the taut state is restored, the conical seat can be separated from the conical frame again to restore the rotation speed, which is satisfactory for current use.

[0015] (2) The fiberglass sand-filled pipe production yarn guide device is provided with a limit insert at the front of the inner cavity of the protective box, and the loosening rod is slidably connected to the protective box. The arrangement of these structures can limit the conical frame by using the conical seat when in use, thereby ensuring the stability of the loosening rod during rotation. The loosening rod can be pulled out and separated from the limit insert, which also facilitates the loading of the wire drum. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5The utility model provides a technical solution: a fiberglass sand-filled pipe production yarn guide device, comprising a protective box 1, both sides of the surface of the protective box 1 are fixedly connected to the vertical guide slide bar 2 by a bracket, and the two vertical guide slide bars 2 are staggered. The surface of the vertical guide slide bar 2 is slidably installed with an arc pressure seat 3, and the rear of the arc pressure seat 3 is fixedly connected to the curved support plate 4 by a fixed block. The upper side of the rear of the curved support plate 4 is rotatably connected to the wire lifting rotating rod 5 through an opening. The surface of the wire lifting rotating rod 5 is fixedly connected to the wire combing wheel 6. The lower part of the surface of the left vertical guide slide bar 2 and the upper part of the surface of the right vertical guide slide bar 2 are both sleeved with a spring 7, and one end of the spring 7 close to the arc pressure seat 3 is fixedly connected to the arc pressure seat 3. The left side of the protective box 1 is fixedly connected to the lead cross bar 15 through a bracket, and the surface of the lead cross bar 15 is provided with a plurality of threading holes for combing and guiding.

[0024] When in use, the electric telescopic rod 13 is started to push the conical seat 14 to separate from the conical frame 12, and then the staff pulls the conical frame 12 to pull the wire loosening rod 11 out from the inner side of the limiting plug 10, and then several winding drums 17 wrapped with yarn are sleeved on the surface of the wire loosening rod 11 using the wire clamping groove 16, and then the wire loosening rod 11 is re-connected with the limiting plug 10. After the connection is completed, the wire loosening rod 11 will use the limiting plug 10 to squeeze and clamp the several winding drums 17 and prevent them from moving left and right.

[0025] Furthermore, the surface of the protective box 1 and the two sides of the arc-shaped pressure seat 3 are fixedly connected with the first button 8 and the second button 9 through the fixing plate, and the first button 8 and the second button 9 are staggered. The front part of the inner cavity of the protective box 1 is rotatably connected to the limit plug 10 through the bearing member, and the rear part of the protective box 1 is slidably installed with a loose wire turning rod 11 used in conjunction with the limit plug 10 through an opening. The top and bottom of the loose wire turning rod 11 are provided with a wire clamping groove 16. The surface of the loose wire turning rod 11 is provided with a winding drum 17 slidably connected to the wire clamping groove 16, and the inner side of the winding drum 17 is provided with a wire clamping groove 16. The card slot 16 is used in conjunction with the card block strip, the rear end of the loosening rod 11 is fixedly connected to the conical frame 12, and the lower rear part of the protective box 1 is fixedly connected to the electric telescopic rod 13 through an opening. The rear end of the electric telescopic rod 13 is fixedly connected to the conical seat 14 used in conjunction with the conical frame 12 through a bracket, and the electric telescopic rod 13 is started to insert the conical seat 14 into the conical frame 12, but it does not contact the conical frame 12. The yarn is then pulled out, passed through the bottom of the right wire lifting rod 5 and the top of the left wire lifting rod 5, and wound in an S shape, and finally pulled out from the hole on the inside of the lead cross bar 15.

[0026] When the yarn is pulled, the left thread-lifting rotating rod 5 is pressed down and the right thread-lifting rotating rod 5 is pulled up. The spring 7 acts on it to rebound to ensure the tension of the yarn. At this time, the arc pressure seat 3 is in the middle position and will not trigger the first button 8 and the second button 9. When the yarn is loose during transmission, the left thread-lifting rotating rod 5 rises and the right thread-lifting rotating rod 5 falls, so that the first button 8 on the left and the second button 9 on the right are pressed by the two arc pressure seats 3 at the same time and the electric telescopic rod 13 is started, which drives the conical seat 14 to contact the conical frame 12, thereby lowering the yarn. The low-loosening thread turning rod 11 drives the rotation speed of the bobbin, so that the relaxed yarn is pulled tight. After the tension is completed, the yarn will use its own tensioning force to press down the left thread lifting turning rod 5 and pull up the right thread lifting turning rod 5, lifting the right arc pressure seat 3 and pressing down the left arc pressure seat 3. In the process of lifting the right arc pressure seat 3 and pressing down the left arc pressure seat 3 to reset, after the arc pressure seat 3 and the first button 8 on the right and the second button 9 on the left are pressed synchronously, the electric telescopic rod 13 pushes the conical seat 14 to separate from the conical frame 12, so that the bobbin resumes its rotation speed.
