Description

Technical Field

[0001] The utility model belongs to the technical field of hose winding production equipment, and particularly relates to an adjustable cross idler. Background Technique

[0002] The technology of winding reinforcing materials on the outer part of a hose is a production process for manufacturing rubber hoses. It combines rubber materials with auxiliary materials (such as fabrics, steel wires, polyester threads, etc.), puts a specific material on the outside of the material composite, and through technological steps such as heating, extrusion, and rotation, makes the composite and the outer layer material firmly bond to form the final hose product.

[0003] When winding reinforcing materials on the outer part of a hose, a support bracket and other structures are used to support the hose so that it can maintain a certain height. However, when facing hoses with different diameters, these brackets often cannot be aligned for effective support. As the adjustment progresses, the contact points between the outer wall of the hose and the support frame may change, thereby changing the stress points of the hose. The continuously moving and rotating hose may fall off the support frame due to the change in the position of the support points, which will affect the subsequent winding production of the hose. Therefore, we hope to design a cross idler with a new structure to solve this problem. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] Please refer to Figures 1 to 4 , the present invention provides a technical solution: an adjustable cross idler, comprising: a mounting base 100, an idler assembly one 200, and an idler assembly two 300. The left side of the upper end of the mounting base 100 is movably installed with an idler assembly one 200, and the right side of the upper end of the mounting base 100 is slidably installed with an idler assembly two 300;

[0030] The mounting base 100 includes a bottom plate 110 and a sliding seat 120. The sliding seat 120 is installed on the upper side of the bottom plate 110 by bolts, and an adjusting screw rod 130 is rotatably installed in the middle of the upper end of the sliding seat 120;

[0031] The idler assembly one 200 includes a mounting bracket 210, a roller one 230, a roller two 240, and a belt 220. The front side of the lower end of the mounting bracket 210 is rotatably installed with a roller one 230, the upper end of the mounting bracket 210 is rotatably installed with a roller two 240, and a belt 220 is rotatably installed between the roller one 230 and the roller two 240. The belt 220 is rotatably installed on the upper side of the mounting bracket 210 through the roller one 230 and the roller two 240.

[0032] Please refer to Figures 1 to 3 , on the left and right sides of the upper surface of the sliding seat 120, a guide rail one 121 is integrally provided respectively. In the middle of the upper surface of the sliding seat 120, a guide rail two 123 is integrally provided. The guide rail two 123 is placed between the two guide rails one 121. In actual use, a plurality of hexagon socket head cap screws are threadedly connected to the upper sides of the two guide rails one, which is convenient for fixing the adjusted idler assembly one 200 and idler assembly two 300, and improving their working stability.

[0033] The cross-section of the guide rail one 121 is an inverted L-shaped structure, the cross-section of the guide rail two 123 is a T-shaped structure, a chute one 122 is provided on the left side of the guide rail two 123, and a chute two 124 is provided on the right side of the guide rail two 123;

[0034] A fixing seat 140 is respectively installed at the front end and the rear end of the upper surface of the second guide rail. The upper ends of the two fixing seats 140 are respectively rotatably connected to the front end and the rear end of the adjusting screw rod 130. Regular hexagonal prism rods are respectively arranged at the front end and the rear end of the adjusting screw rod 130.

[0035] The specifications of the first chute 122 are the same as those of the second chute 124. The upper side, the front end and the rear end of the first chute 122 and the second chute 124 are all designed with openings. The cross-sections of the first chute 122 and the second chute 124 are both in a convex-shaped structure.

[0036] As the first embodiment of the present utility model, during actual use, if it is necessary to adjust the upper supporting spacing of the first idler assembly 200 and the second idler assembly 300, the user first loosens the hexagon socket head cap screw on the first guide rail 121, so that the first idler assembly 200 and the second idler assembly 300 are released from fixation. At this time, the user uses an external wrench to turn the regular hexagonal prism rod at the front end of the adjusting screw rod 130, so that the adjusting screw rod 130 rotates on the two fixing seats 140. Since a nut seat 250 is respectively fixed to the lower front side of the right end of the first idler assembly 200 and the lower rear side of the left end of the second idler assembly 300, and through holes are respectively formed in the two nut seats 250 from front to back to form a threaded hole 251, the thread spiral directions in the threaded holes 251 on the two nut seats 250 are opposite, and the two nut seats 250 are respectively threadedly connected to the adjusting screw rod 130 through their respective corresponding threaded holes 251. The in-situ rotating adjusting screw rod 130 makes the two nut seats 250 move towards each other or in opposite directions, and further makes the first idler assembly 200 and the second idler assembly 300 move towards each other or in opposite directions, so as to achieve the purpose of adjusting the upper supporting spacing of the first idler assembly 200 and the second idler assembly 300;

[0037] Since the roller belt 220 is always in a forty-five-degree state, and the first idler assembly 200 and the second idler assembly 300 are installed in a cross-opposite direction, even if the first idler assembly 200 moves forward and the second idler assembly 300 moves backward, the inclination angle of the roller belt 220 will not be changed. That is, for hoses with different diameters, their outer walls are always connected to the roller belt 220 on the first idler assembly 200 and the second idler assembly 300 at an angle of forty-five degrees. For hoses with different diameters, the first idler assembly 200 and the second idler assembly 300 can uniformly support their outer walls at an angle of forty-five degrees, and the position of the supporting force point will not be changed. Furthermore, the normal winding work of hoses with different diameters can be ensured, and the situation of falling due to the change of the supporting point will not occur.

[0038] Waist-shaped holes 211 are respectively arranged at an inclination of forty-five degrees on the left side and the right side of the upper end of the mounting frame 210. The inclination direction and angle of the waist-shaped holes 211 are the same as the inclination direction and angle of the roller belt 220;

[0039] On the left end and the right end of the second rotating roller 240, a fixing rod 241 is rotatably installed respectively. The two fixing rods 241 are slidably installed in the waist-shaped holes 211 on the left side and the right side of the upper end of the mounting frame 210 respectively. The outer ends of the fixing rods 241 extend out of the waist-shaped holes 211. In actual use, a slide bar is provided on each of the left side and the right side of the lower end of each mounting frame 210. The lower end of the mounting frame 210 is slidably connected with the first guide rail 121 and the second guide rail 123 through the slide bars, and the adjusting screw rod 130 and the nut seat 250 are cooperated to achieve the purpose of adjusting the first roller assembly 200 and the second roller assembly 300.

[0040] Please refer to Figures 2 to 4 , on the left side and the right side of the upper end of the mounting frame 210, a sloping plate 212 is welded at an angle of 45 degrees respectively. The sloping angle of the sloping plate 212 is perpendicular to the sloping angle of the rolling belt 220. On each sloping plate 212, a screw knob 213 is threadedly connected at an angle of 45 degrees;

[0041] The sloping direction and angle of the screw knob 213 are the same as the sloping direction and angle of the rolling belt 220. The upper end of the screw knob 213 is rotatably connected with the outer end of the fixing rod 241 at an angle of 45 degrees.

[0042] The specifications of the first roller assembly 200 are the same as those of the second roller assembly 300. A nut seat 250 is fixed on the lower front side of the right end of the first roller assembly 200 and the lower rear side of the left end of the second roller assembly 300 respectively;

[0043] Both of the two nut seats 250 are formed with a threaded hole 251 penetrating from front to back. The thread helix directions in the threaded holes 251 on the two nut seats 250 are opposite. The two nut seats 250 are threadedly connected with the adjusting screw rod 130 through their respective corresponding threaded holes 251.

[0044] As the second embodiment of the present invention, based on the above first embodiment, in actual use, if the rolling belt 220 becomes loose and changes the state of the tension degree at an angle of 45 degrees, the user can tighten the screw knob 213 to push the position of the fixing rod 241 in the waist-shaped hole 211, and then drive the distance between the second rotating roller 240 and the first rotating roller 230, so that the rolling belt 220 is tightened. Since the waist-shaped hole 211 is set at an angle of 45 degrees, the movement of the fixing rod 241 always moves along the angle of 45 degrees, and it will not cause the change of the inclination degree of the rolling belt 220 after being tightened, ensuring that it always supports the hose at an angle of 45 degrees.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
