Description

Technical Field

[0001] The utility model belongs to the field of wire and cable manufacturing equipment, and relates to an automatic shrinking reel device for a medium-sized high-speed braiding machine. Background Art

[0002] The core of some cables is a highly elastic hollow hose, which requires a mesh metal layer to be braided onto the surface. After braiding, the hose is removed from the side of the reel and stored in a coil. Due to the characteristics of the material, the hose stretches slightly under the reeling force during braiding. After braiding, the hose retracts and clings to the reel core, preventing it from being smoothly removed from the side of the reel. Plumbing pipe manufacturers use reeling machines to unwind the braided hose from the reel and manually coil it for storage, which severely impacts production efficiency and product quality.

[0003] Therefore, an automatic retractable wire drum device for a medium-sized high-speed braiding machine is designed to overcome the above problems. Utility Model Content

[0017] In order to enable those skilled in the art to more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0018] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inside", "outside", "horizontal", and "vertical" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or original referred to must have a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0019] The present invention will be described in detail below with reference to the accompanying drawings: Figure 1-2 As shown, an automatic retracting wire drum device of a medium-sized high-speed braiding machine includes a frame 3 and a main shaft 6 installed on the frame 3. The main shaft 6 is fixed to the frame 3 through a bearing 5 and a bearing sleeve 4. The main shaft 6 is connected to the driving mechanism, and the main shaft 6 is driven to rotate by the driving mechanism. A fixed baffle 7, a sleeve 11 and a movable baffle 13 are respectively provided on the main shaft 6, wherein the fixed baffle 7 is fixedly installed on the side of the main shaft close to the driving mechanism, and the movable baffle 13 is detachably installed on the side of the main shaft away from the driving mechanism, and a locking head mechanism is provided at the end position of the main shaft 6 on the outside of the movable baffle 13 for fixing the movable baffle 13. A sleeve 11 is provided between the fixed baffle 7 and the movable baffle 13, and a parallel linkage mechanism is installed on the sleeve 11. The sleeve 11 and the parallel linkage mechanism constitute a retractable wire drum. After the cable braiding work is completed, the locking head mechanism and the movable baffle 13 are removed in turn, and the parallel linkage mechanism is retracted to take out the braided cable. The driving mechanism is a motor 1 with a reduction gearbox 2.

[0020] The locking head mechanism consists of a threaded taper sleeve 14, a fixed screw sleeve 15 and a handle screw 16. The threaded taper sleeve 14 is sleeved and installed on the outer circular thread of the main shaft 6, so that the threaded taper sleeve 14 supports the movable baffle 13, which is used to ensure the normal operation of the sleeve 11 and the parallel connecting rod mechanism arranged between the movable baffle 13 and the fixed baffle 7. A fixed screw sleeve 15 is sleeved on the main shaft 6 on the side of the threaded taper sleeve 14 away from the movable baffle 13, which is used to lock the handle screw 16. By removing the handle screw 16, the fixed screw sleeve 15 and the threaded taper sleeve 14 in sequence, the movable baffle 13 can be detachably installed.

[0021] The parallel linkage mechanism is at least one group, and each group of parallel linkage mechanisms is composed of an arc plate fixing strip 9, a sleeve fixing strip 10, two connecting plates 12 and an arc plate 8. The arc plate 8 is arranged around the outer side of the sleeve 11, and the arc plate fixing strip 9 is installed on the inner side of the arc plate 8, and the sleeve fixing strip 10 is installed on the outer side of the sleeve 11. Between the arc plate fixing strip 9 and the sleeve fixing strip 10, a connecting plate 12 is installed on both sides of the arc plate fixing strip 9 and the sleeve fixing strip 10. The two ends of each connecting plate 12 are respectively connected to the arc plate fixing strip 9 and the sleeve fixing strip 10 by bolts. The position of the arc plate 8 is adjusted by rotating the angle of the connecting plate 12 to adjust the contraction of the entire parallel linkage mechanism.

[0022] Among them, the adjustment and fixation of the connecting plate can be achieved by loosening the bolts to adjust the angle, and then tightening the bolts to fix it after the angle is adjusted. It can also be achieved through a conventional locking mechanism, which can be locked after the angle is adjusted, thereby achieving the angle adjustment of the connecting plate and fixation after the angle adjustment.

[0023] There are six groups of parallel linkage mechanisms, which are evenly arranged around the outer side of the sleeve 11 and the same spacing is set between two adjacent groups of parallel linkage mechanisms, so that the six groups of parallel linkage mechanisms after installation form a discontinuous circular structure. The driving mechanism drives the main shaft 6 to rotate and drive the sleeve 11 to operate. After the cable braiding work is completed, the braided cable can be easily taken out by contracting the parallel linkage mechanism.

[0024] Of course, the number of six groups is a preferred value, and the specific number can be adjusted according to actual needs without any limitation.

[0025] The cable drum of the present invention is composed of a discontinuous circle consisting of multiple arc-shaped plates, and each arc-shaped plate is equipped with a set of parallel connecting rod mechanisms, so as to realize the contraction and adjustment of the cable drum, which is convenient for taking out the braided cable. The present invention is provided with a quick locking head mechanism with thread adjustment composed of a threaded cone sleeve, a fixed screw sleeve and a handle screw, so as to ensure convenient and quick loading and unloading, making the whole more practical and convenient, and well overcoming the problem that the core wire of some existing cables is a highly elastic hollow rubber hose, and there is a problem that the rubber hose shrinks after braiding and hugs the cable drum core, making it impossible to smoothly detach from the cable drum from the side of the cable drum.

[0026] For ease of understanding, we provide Figure 3-4 It is an axial and radial cross-sectional view of the utility model in the contracted state.

[0027] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, any equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this utility model shall be covered by the claims of this utility model.
