Description

Technical Field

[0001] The utility model relates to a double-layer hose folding device, belonging to the technical field of hose automation production. Background Art

[0002] At present, in the field of hose production, the pipe sleeve method is generally adopted, that is, the outer tube is directly sleeved on the inner tube. The applicant proposes to manufacture double-layer hoses by stacking double-layer sheets first and then rolling them into pipes and then welding them. Among them: there is currently no device for stacking double-layer sheets first and then rolling them into pipes. The existing technology only has a device for rolling single-layer sheets into pipes. Utility Model Content

[0003] The utility model provides a double-layer hose folding device and a folding process, which solves the problem in the prior art that there is no corresponding device for first stacking the double-layer hose and then rolling it into a pipe.

[0004] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0005] A double-layer hose folding device, the folding device includes several pairs of gradient rollers and a platform, each of the gradient rollers includes a fixed shaft and a roller, the fixed shaft is rotatably mounted on the roller fixing frame of the platform, and the fixed end of the fixed shaft is arranged on the platform, the free end of the fixed shaft is arranged obliquely relative to the platform, the roller is sleeved on the fixed shaft, and is used to drive the two sides of the double-layer sheet to fold toward the middle when the fixed shafts on each pair of gradient rollers rotate relative to the roller fixing frame and come close to each other, so as to finally fold into a double-layer tube.

[0006] Preferably, there are six pairs of the gradient rollers, and according to the forward direction of the hose on the platform, the outer angles between the fixed axes of the six gradient rollers and the roller fixing frames are set at 22.5°, 45°, 67.5°, 90°, 112.5°, and 135°.

[0007] Preferably, the outer angle between the fixed end of each gradient roller and the platform is gradually increased by adjusting the gradient adjusting device.

[0008] Preferably, the gradual adjustment device includes a handwheel, a screw, and the fixed end of the fixed axis of the gradual roller is hinged on the roller fixing frame. The screw is threadedly sleeved on the platform, and a connecting block is threadedly sleeved on the screw. The other end of the connecting block is slidably sleeved on the roller fixing frame, and a bayonet is provided on the connecting block, which corresponds to the fixed end of the gradual roller, and the handwheel is installed at one end of the screw.

[0009] The purpose of adopting the above scheme is to first manually rotate the fixed shaft through the hinge between the fixed shaft and the roller fixing frame, and then drive the screw to rotate by turning the hand wheel. Since the connecting block is slidably arranged on the roller fixing frame, the connecting block is driven to move under the rotation of the screw, so that the bayonet on the connecting block clamps the fixed shaft, and finally the gradient roller is deflected relative to the platform and fixed.

[0010] Preferably, there are six pairs of gradient rollers, and the fixed axes of the six gradient rollers located on the same side of the top of the platform are driven together by the output end of the cylinder with the roller fixing frame, so as to close the six pairs of gradient rollers on both sides of the top of the platform at the same time, thereby driving the two sides of the double-layer sheet to fold toward the middle, and finally fold into a double-layer tube.

[0011] The beneficial effects of the utility model are:

[0012] The utility model uses six pairs of gradient rollers arranged on the production line to make the raw materials change from sheet to roll when the traction equipment moves forward, so as to complete the operation of folding the double-layer hose or directly place it on the six pairs of gradient rollers, and uniformly drive the gradient rollers through cylinders to make the two sides of the double-layer sheet fold toward the middle, and finally fold into a double-layer hose, thereby solving the problem that the two-layer sheet cannot be folded in the prior art. In addition, since each pair of gradient rollers is required according to the tube diameter of the hose, it is only necessary to adjust the gradient adjustment device to change the angle of each pair of gradient rollers relative to the production line, so the production cycle is short and the efficiency is improved.

[0018] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific illustrations and embodiments.

[0019] The double-layer hose adopted by the utility model is a double-layer sheet rolled into a tube, and two sheets of different materials and the same width are stacked in sequence, that is, a sheet is placed first, and then a sheet of another material is placed on top of the sheet, but the two sheets are the same or different in width, and then under the manual traction at the end of the platform, the double-layer sheet is folded into a double-layer tube by the folding device of the present invention, and then the gap is connected and sealed by the existing technology (the specific connection method is not limited to the welding connection method), and finally a double-layer hose is made; that is,

[0020] like Figure 1-3 As shown, the double-layer hose folding device includes a platform, on which are arranged a plurality of pairs of gradient rollers 2 (each gradient roller 2 includes a fixed shaft and a roller, and the fixed shaft is mounted on a roller fixing frame 34 of the platform), each gradient roller 2 includes a fixed end and a free end, the fixed end is arranged on the platform, and the free end is arranged obliquely relative to the platform (specifically: there are six pairs of gradient rollers 2, and according to the forward direction of the hose on the platform, the outer angles between the fixed shafts of the six gradient rollers 2 and the roller fixing frames are set at 22.5°, 45°, 67.5°, 90°, 112.5°, and 135°), and the outer angles between the fixed ends of each front and rear adjacent gradient rollers 2 and the platform are gradually increased by adjusting a gradient adjusting device 3 (specifically: the gradient adjusting device 3 includes a hand wheel 31, a screw rod 32, and a fixed end hinge of the fixed shaft of the gradient roller 2 On the roller fixing frame 34, the screw rod 32 is threadedly sleeved on the platform, and a connecting block 33 is threadedly sleeved on the screw 32. The other end of the connecting block 33 is slidably sleeved on the roller fixing frame 34, and a bayonet is provided on the connecting block 33, which corresponds to the fixed end of the gradient roller 2. The hand wheel 31 is installed at one end of the screw rod 32. The above scheme is adopted for the purpose of first manually rotating the fixed shaft through the hinge between the fixed shaft and the roller fixing frame 34, and driving the screw rod 32 to rotate by rotating the hand wheel 31. Since the connecting block 33 is slidably arranged on the roller fixing frame 34, the connecting block 33 is driven to move under the rotation of the screw rod 32, so that the bayonet on the connecting block 33 clamps the fixed shaft, and finally the gradient roller 2 is deflected and fixed relative to the platform). The double-layer sheet walks on the platform and is gradually restricted by the six pairs of gradient rollers 2, and is finally folded into a double-layer tube.

[0021] It should be noted that a cylindrical roller 4 is provided on the platform, and the height of the cylindrical roller 4 is higher than the roller fixing column. The double-layer sheet is folded under the six pairs of gradient rollers of the platform through manual or mechanical traction at the end of the platform, and finally folded into a double-layer tube.

[0022] After the double-layer pipe is folded into place by the folding device, the gap on the double-layer pipe can be sealed by a connection method other than welding.

[0023] It should be noted that when the pipe winding operation begins, one end of the double-layer pipe needs to be manually or mechanically pulled so that it passes through six pairs of gradient rollers whose angles have been adjusted on the production line in turn. The subsequent hoses pass through the six pairs of gradient rollers in turn and move forward while completing the winding operation.

[0024] It should be noted that the production of double-layer pipes with different diameters can be achieved by adjusting the angles of the six pairs of gradient rollers 2 relative to the platform.

[0025] The present application may also have other implementation modes, that is, Figure 4 As shown, there are six pairs of gradient rollers 2, and a cylinder is installed between the fixed shafts of the six gradient rollers on the same side of the top of the platform and the roller fixing frame. The cylinder on the same side of the top of the platform is used to simultaneously drive the six gradient rollers at the same position as the cylinder, so that the six pairs of gradient rollers on both sides of the top of the platform are closed at the same time, thereby driving the two sides of the double-layer sheet to fold toward the middle, and finally folded into a double-layer tube.

[0026] The present application may also have other implementations, that is, the dry hose of the present invention may also adopt another structure, in which the outer layer of the dry hose is made of TPU and the inner layer is made of polyester mesh non-woven fabric.

[0027] The utility model proposes a new double-layer hose folding device, which solves the folding problem of the double-layer hose and finally solves the production problem of the double-layer hose;

[0028] The utility model uses six pairs of gradient rollers arranged on the production line to make the raw materials change from sheet to roll when the traction equipment moves forward, so as to complete the operation of folding the double-layer hose or directly place it on the six pairs of gradient rollers, and uniformly drive the gradient rollers through cylinders to make the two sides of the double-layer sheet fold toward the middle, and finally fold into a double-layer hose, thereby solving the problem that the two-layer sheet cannot be folded in the prior art. In addition, since each pair of gradient rollers is required according to the tube diameter of the hose, it is only necessary to adjust the gradient adjustment device to change the angle of each pair of gradient rollers relative to the production line, so the production cycle is short and the efficiency is improved.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
