[0003] At present, the small-angle belt joint angle that can be cut by cutting equipment is generally between 15° and 75°.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0033] like Figures 2 to 13As shown, the present invention discloses a winding head device 1 with adjustable cutting angle (hereinafter referred to as winding head device), comprising a fixed frame 10, on which a material delivery mechanism 20 is movably arranged along the conveying direction of the belt layer, and the material delivery mechanism 20 is used to deliver the crown band strip material head; a pressing assembly 30 is fixedly arranged on the fixed frame, and the pressing assembly 30 is used to press the crown band strip material head down to the belt drum G; it also includes a rotating mechanism 40 arranged on the fixed frame 10, and a cutting mechanism 50 connected to the rotating mechanism 40, the cutting mechanism includes a movable upper cutting knife 51 and a lower cutting knife 52, and the cutting mechanism 50 is rotatable by the rotating mechanism 40, so as to adjust the cutting angle of the upper cutting knife 51 and the lower cutting knife 52 to the belt layer. Through the above-mentioned arrangement, when the winding head device winds the crown strip into a first winding layer at a first winding angle on the belt drum G, it is cut at a first cutting angle; then the winding head device winds the crown strip into a second winding layer cross-symmetrical with the first winding layer at a second winding angle on the belt drum, and cuts it at a second cutting angle, thereby forming a belt layer with a cross-winding layer, the gap areas formed on the cross-winding layer and the two side edges of the belt drum are of the same size and the cutting angles of the winding layers are symmetrical.

[0034] When in use, the belt layer head is first pressed down onto the belt drum G by the pressing assembly 30, and the belt layer is wound in the form of a belt drum G rotating and a winding head device 1 moving. Fig.12 The first winding angle α1 shown is wound onto the belt drum G. After being wound to a specified length, the upper cutter 51 is moved together with the lower cutter 52 to cut the belt layer on the lower cutter 52 at a first cutting angle β1, and then the belt layer head is sent out of the cutting position by the material delivery mechanism 20, so as to carry out the winding of the next belt layer, and the first winding layer CR1 wound at the first winding angle α1 is completed repeatedly; Fig.13 As shown, when the winding head device rotates a certain angle to wind the second winding layer CR2 which is arranged crosswise with the first winding layer CR1 on the belt drum G, the cutting angle of the belt layer also needs to change. The cutting mechanism 50 is rotated at a certain angle by the rotating mechanism 40 to change the angles of the upper cutting knife 51 and the lower cutting knife 52 relative to the belt layer, thereby changing the cutting angle of the belt layer, so that the belt layer is cut at the second cutting angle β2; then repeat the above-mentioned belt layer winding, cutting, and material delivery operations to complete the second winding layer CR2 wound at the second winding angle α2, and the first winding layer CR1 and the second winding layer CR2 are arranged crosswise to form a cross winding layer. Different cutting angles of the cross winding layers are achieved by the rotating mechanism 40, so as to meet the different winding angles of the belt layer. The belt layer described in the present invention can be wound around the belt drum G for one circle, or a specified length less than one circle.

[0035] like Figures 2 to 5As shown, the winding head device of the present invention further includes a support seat 61, the support seat 61 is fixedly arranged on the fixed frame 10, and further includes a rotating connecting member 71 rotatably arranged in the support seat through a first bearing member 711, the rotating mechanism 40 includes a first rotating driving source 41 fixedly arranged on the support seat 61, and a first transmission device 42 driven by the first rotating driving source 41, one end of the first transmission device 42 is fixedly arranged with the rotating connecting member 71, and the cutting mechanism 50 is arranged in the rotating connecting member 71, when the first rotating driving source 41 drives the rotating connecting member 71 to rotate through the first transmission device 42, the cutting mechanism 50 arranged in the rotating connecting member 71 is driven to rotate together to adjust the cutting angle. Preferably, the first transmission device 42 is a gear transmission mechanism.

[0036] It should be noted that a slot 611 penetrating the side wall of the support seat 61 is provided, and the first transmission device 42 includes a first gear 421 and a second gear 422, and the first gear 421 and the second gear 422 are meshedly arranged at the slot 611 of the support seat, thereby realizing that the first rotating drive source 41 arranged outside the support seat 61 drives the rotating connection member 71 arranged inside the support seat 61 to rotate.

[0037] It also includes a cutting base 62 fixedly connected to the support base 61. The cutting base 62 can be integrally or separately arranged with the support base 61. A feed port 63 and a discharge port 64 are arranged between the support base 61 and the cutting base 62. The belt layer enters the cutting mechanism 50 from the feed port 63 and is then output from the discharge port 64.

[0038] like Figure 3 As shown, the cutting mechanism 50 of the present invention comprises a cutting driving source 53 fixedly arranged on a support seat 61, and an upper knife seat 54 movably arranged in a rotating connecting member 71 through a first moving assembly 541, wherein the upper cutting knife 51 is fixedly arranged on the upper knife seat 54; and further comprises a lower knife seat 55 rotatably arranged on a cutting base 62 through a second bearing member 551, wherein the lower cutting knife 52 is fixedly arranged on the lower knife seat 55, and the rotating connecting member 71 is connected to the lower knife seat 55. When the rotating mechanism 40 drives the rotating connecting member 71 to rotate, the upper knife seat 54 arranged in the rotating connecting member 71 and the lower knife seat 55 connected to the rotating connecting member 71 are driven to rotate, thereby driving the upper cutting knife 51 respectively arranged on the upper knife seat 54 and the lower cutting knife 52 arranged on the lower knife seat 55 to rotate together, thereby adjusting the cutting angle of the belt layer. Preferably, the first moving assembly can be a combination of a slide rail and a slider or a combination of a connecting member and a keyway.

[0039] like Figure 5As shown, the upper cutter 51 and the lower cutter 52 are arranged opposite to each other. When the upper cutter 51 moves downward to cut the belt layer, the upper cutter 51 contacts the lower cutter 52 to cut the belt layer arranged between the upper cutter 51 and the lower cutter 52. Preferably, the lower cutter seat 55 is provided with a cutting opening 512 arranged opposite to the upper cutter 51. The cutting opening 512 may be arranged through the lower cutter seat 55 or may not be arranged through the lower cutter seat 55. When the upper cutter 51 moves downward to contact the lower cutter 52, the upper cutter 51 is placed at the cutting opening 512 in the lower cutter seat 55 to avoid interference between the upper cutter 51 and the lower cutter seat 55 during cutting.

[0040] Due to space limitations, the rotating connector 71 is connected to the lower knife seat 55 via a plurality of columns 81. When the upper cutter 51 moves downward and contacts the lower cutter 52, the force of the lower cutter 52 is transmitted to the lower knife seat 55, which may cause the column 81 to be unable to withstand the force and break. Therefore, in order to avoid the column 81 from being broken by force, the rotating connector 71 and the lower knife seat 55 are floatingly connected via a connecting mechanism 80. The connecting mechanism 80 includes a column 81 that passes through the lower knife seat 55 and is threadedly connected to the rotating connector 71, and an elastic element 82 is provided at the portion of the column 81 between the lower knife seat 55 and the rotating connector 71. Through the above arrangement, when the column 81 is subjected to force, the force is transmitted to the lower knife seat 55 through the elastic element 82, thereby avoiding the column 81 from being broken by force.

[0041] As a winding head device with simpler structure and better cutting effect, such as Figures 6 to 10 The figure shows a second embodiment of the winding head device described in the present invention, wherein the support seat 61 is rotatably arranged on the fixed frame 10 through a third bearing member 612, and the cutting mechanism 50 is arranged in the support seat 61. The rotating mechanism 40 is a first rotating driving source 41 fixedly arranged on the fixed frame 10, and the driving end of the first rotating driving source 41 is fixedly connected to the support seat 61. When the first rotating driving source 41 drives the support seat 61 to rotate, the cutting mechanism 50 arranged on the support seat 61 is driven to rotate together.

[0042] It also includes a cutting base 62 fixedly connected to the support base 61. The cutting base 62 can be integrally or separately arranged with the support base 61. A feed port 63 and a discharge port 64 are arranged between the support base 61 and the cutting base 62. The belt layer enters the cutting mechanism 50 from the feed port 63 and is then output from the discharge port 64.

[0043] In this embodiment, the cutting mechanism 50 further includes a cutting drive source 53 fixedly arranged on the support seat 61, and an upper knife seat 54 movably arranged in the support seat 61 through a second moving component 542, wherein the upper knife 51 is fixedly arranged on the upper knife seat 54; the lower knife 52 is arranged on the cutting base 62; and the driving end of the cutting drive source 53 is connected to the upper knife seat 54. When in use, the cutting drive source 53 drives the upper knife seat 54 to move up and down in the support seat 61, driving the upper knife 51 to move up and down, and when the upper knife 51 approaches the lower knife 52 and contacts the lower knife 52, the belt layer is cut, and when the upper knife 51 moves away from the lower knife 52 and separates from the lower knife 52, the belt layer is allowed to pass through. The second moving component 542 is a combination of a slide rail and a slider or a combination of a connector and a keyway.

[0044] like Fig.10 As shown, in this embodiment, the cutting opening 512 is arranged on the cutting base 62. When the upper cutting knife 51 moves downward and contacts the lower cutting knife 52, the upper cutting knife 51 is placed at the cutting opening 512 on the cutting base 62 to avoid interference between the upper cutting knife 51 and the cutting base 62 during cutting.

[0045] like Fig.11 As shown, the material pressing assembly 30 of the present invention is arranged near the discharge port 64 of the rotating mechanism 40, and the material pressing assembly 30 includes a mounting frame 31 fixedly arranged on the fixed frame 10, a material pressing driving source 32 is fixedly arranged on the mounting frame 31, and a rotatable pressing roller 33 is movably arranged on the mounting frame 31 through a third moving assembly 331, and the driving end of the material pressing driving source 32 is fixedly arranged with the pressing roller 33. When the material pressing driving source 32 drives the pressing roller 33 to move in a direction close to the belt drum G, the pressing roller 33 contacts the belt drum G and presses the belt layer down onto the belt drum G; when the material pressing driving source 32 drives the pressing roller 33 to move in a direction away from the belt drum G, the pressing roller 33 separates from the belt drum G. Preferably, the third moving assembly is a combination of a slide rail and a slider.

[0046] Since the winding head device of the present invention splices the cap strips one by one on the surface of the belt drum G to form a belt layer, the cap strips need to be arranged according to certain requirements. Since the winding head device of the present invention needs to cut the cap strips at two different cutting angles when producing a belt layer of a certain specification, in order to cover the above two cutting angles, the discharge port 64 of the present invention is larger than the width of the cap strip, so the cap strip will easily deviate within the range of the discharge port 64 during the winding process. In order to prevent the position of the cap strip from deviating from the set position during the winding process of the cap strip, a limiting mechanism 90 is also provided at the discharge port 64 of the present invention. The limiting mechanism 90 includes a rotatable rotating member 91, and a first guide member 92 and a second guide member 93 arranged above the rotating member 91 and with an adjustable spacing. The cap strip is transported within the range limited by the first guide member 92 and the second guide member 93. By adjusting the position and spacing between the first guide member 92 and the second guide member 93, the winding position of the cap strip is limited.

[0047] like Figure 2 and 6 As shown, the material delivery mechanism 20 of the present invention includes a material delivery frame 21 movably arranged on the fixed frame 10 through a fourth moving component 211 and a material delivery driving source 22 fixedly arranged on the fixed frame 10, the driving end of the material delivery driving source 22 is connected to the material delivery frame 21, a material delivery plate 23 is fixedly arranged on the material delivery frame 21, and also includes a stopper 24 rotatably arranged on the material delivery frame 21, the stopper 24 is arranged above the material delivery plate 23, and is used to stop the crown band strip from retreating. When the cutting mechanism 50 completes the cutting of the crown band strip and winds the next crown band strip, the material delivery driving source 22 drives the material delivery frame 21 to move, thereby driving the material delivery plate 23 to move toward the direction close to the feed port 63, and driving the crown band strip material head placed on the material delivery plate 23 to pass through the cutting position between the upper cutting knife 51 and the lower cutting knife 52 and the discharge port 64 to reach the belt drum G.

[0048] Preferably, the first rotation drive source 41 of the present invention may be a motor or a cylinder. The cutting drive source 53 may be a motor, a cylinder or a hydraulic cylinder. In order to better meet the cutting force requirements, the cutting drive source 53 is preferably a hydraulic cylinder.

The relationship between the second cutting angle β2 and the first cutting angle β1 is β2=180°-β1, where β1 and β2 are any angles between 0 and 180 degrees. A symmetrical winding layer is formed by the relationship between the first winding angle α1 and the second winding angle α2, and by the relationship between the first cutting angle β1 and the second cutting angle β2, the cutting angle of the crown strip on the first winding layer CR1 is symmetrical with the cutting angle of the crown strip on the second winding layer CR2 to meet the process requirements.
