Description

Technical Field

[0001] The utility model relates to the technical field of cloth cutting machines, in particular to a rotatable ultrasonic cutting head. Background Art

[0002] The ultrasonic shearing machine combines ultrasonic welding technology with traditional shearing. When the ultrasonic generator is working, the ultrasonic energy is transmitted to the welding head through the ultrasonic transducer and produces violent vibration and friction with the knife die, thereby achieving the shearing effect, making the sheared products more beautiful, stronger, and more efficient and faster in production.

[0003] In the prior art, the blade of the ultrasonic shearing machine can only be driven by a driving device to move horizontally or vertically to cut the cloth. If a cloth needs to be cut horizontally, vertically, and obliquely, after completing the horizontal cutting and vertical cutting, it is necessary to readjust the direction of the cloth to complete the oblique cutting of the cloth. This process requires two feeding operations to complete the oblique cutting of the cloth. Since the feeding operation needs to be repeated, the efficiency of the cloth cutting operation is low.

[0004] The ultrasonic cloth cutting machine uses high-frequency oscillation to transmit sound waves from the welding head to the welding surface of the workpiece, instantly causing the molecules of the workpiece to produce friction and reach the melting point of the product, thereby quickly dissolving the solid material and completing the cutting edge, so that the cloth can be cut.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0006] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a rotatable ultrasonic cutting head to effectively solve the technical defect of low cutting efficiency of ultrasonic shearing machines in the prior art.

[0008] The beneficial effect of the rotatable ultrasonic cutting head provided by the present application is that, compared with the prior art, by providing a rotatably mounted cutter, the cutter can be driven to rotate by the fourth driving mechanism; during operation, the cutter can be driven to move and rotate its angle by the first driving mechanism, the second driving mechanism, the third driving mechanism and the fourth driving mechanism, so that the cloth can be loaded once to complete multi-angle and multi-directional cloth cutting operations, thereby reducing the number of repeated cloth loading times and thereby improving the efficiency of cloth cutting.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Please also read Figures 1 to 3 Now, the rotatable ultrasonic cutting head provided in the embodiment of the present application is described. The rotatable ultrasonic cutting head comprises: a frame 10.

[0030] The frame 10 is movably mounted with a first crossbeam 11, which is driven by a first driving mechanism 12 to move in the front-rear direction of the frame 10; the first crossbeam 11 is movably mounted with a first movable plate 13, which is driven by a second driving mechanism 14 to move in the left-right direction of the first crossbeam 11; the first movable plate 13 is movably mounted with a second movable plate 15, which is driven by a third driving mechanism 16 to move up and down; the second movable plate 15 is rotatably mounted with a cutter 17, which is driven to rotate by a fourth driving mechanism 18, thereby adjusting the cutting direction of the cutter 17.

[0031] Specifically, a rotatable cutter 17 is provided, and the cutter 17 is driven to rotate by the fourth drive mechanism 18; the movement trajectory of the cutter 17 is adjusted in cooperation with the first drive mechanism 12, the second drive mechanism 14 and the third drive mechanism 16, so that the cutter 17 can cut the cloth in multiple directions and at multiple angles; that is, when cutting the cloth, the cutter 17 can move horizontally and vertically at the same time to achieve oblique cutting of the cloth; the angle of the cutter 17 can also be rotated while the cutter 17 moves horizontally and vertically, so as to cut cloth in arc-shaped, wavy and other shapes; such a structure can enable the cloth to be loaded once to complete the cloth cutting operation at multiple angles and directions, thereby reducing the number of repeated loading of the cloth, thereby improving the efficiency of cloth cutting.

[0032] In some embodiments of the present application, the first driving mechanism 12 includes a first transmission rack 121 installed on the frame 10 and a first motor 122 installed on the first crossbeam 11, and the rotating shaft of the first motor 122 is provided with a first transmission gear 123 meshingly connected with the first transmission rack 121. The second driving mechanism 14 includes a second transmission rack 141 installed on the first crossbeam 11 and a second motor 142 installed on the second movable plate 15, and the rotating shaft of the second motor 142 is provided with a second transmission gear meshingly connected with the second transmission rack 141.

[0033] Specifically, the first drive mechanism 12 and the second drive mechanism 14 are both driven by the cooperation of a motor and a rack, which has a simple structure and is reliable to use. At the same time, since the first drive mechanism 12 and the second drive mechanism 14 have the same components, the versatility of the equipment is improved.

[0034] In some embodiments of the present application, the third driving mechanism 16 is a third cylinder installed on the first movable plate 13, and the telescopic rod of the third cylinder is connected to the second movable plate 15; when the telescopic rod of the third cylinder is extended and retracted, it can drive the second movable plate 15 to move up and down. The second movable plate 15 is provided with a first rotating seat 151, and the cutter 17 can be rotatably installed on the first rotating seat 151; the fourth driving mechanism 18 includes a fourth motor 181, a fourth driving gear 182 installed on the rotating shaft of the fourth motor 181, and a fourth driven gear 183 installed on the cutter 17, and the fourth driving gear 182 is meshed and connected with the fourth driven gear 183.

[0035] It should be noted that the displacement paths of the first crossbeam 11 , the first movable plate 13 and the second movable plate 15 are all limited by the cooperation between the guide rail and the slider, which is a conventional design method for those skilled in the art and will not be elaborated here.

[0036] Next, the cutter 17 includes a fixing portion 171 and a cutting portion 172, and the cutting portion 172 is arranged in a flat shape. The cutting portion 172 arranged in a flat shape can reduce the loss of the cloth during cutting and prevent excessive waste during cutting.

[0037] In some other embodiments of the present application, a first cloth pressing device 19 and a second cloth pressing device 100 are also included. The first cloth pressing device 19 is installed on the first beam 11, and the second cloth pressing device 100 is installed on the first movable plate 13; when the cutter 17 cuts the cloth horizontally, the first cloth pressing device 19 presses the cloth; when the cutter 17 cuts the cloth longitudinally, the second cloth pressing device 100 presses the cloth.

[0038] Specifically, by setting up the first cloth pressing device 19, when it is necessary to cut the cloth transversely, the cloth can be pre-pressed by the first cloth pressing device 19, and then the cloth is cut transversely, which can ensure that the cloth is not prone to bend during the cutting process, thereby improving the accuracy of cloth cutting and the flatness of the cut; correspondingly, when it is necessary to cut the cloth longitudinally, the cloth can be pressed by the second cloth pressing device 100.

[0039] In more detail, there are two first cloth pressing devices 19, which are respectively installed on the front and rear sides of the first beam 11; each first cloth pressing device 19 includes a plurality of first cylinders 191 installed on the first beam 11 and a first pressing plate 192 installed on the telescopic rod of the first cylinder 191.

[0040] Next, the second cloth pressing device 100 includes a second lower pressing plate 1001 movably mounted on the first movable plate 13, a second cylinder 1002 mounted on the first movable plate 13 and used for driving the second lower pressing plate 1001 to move up and down, and a first lower pressing wheel 1003 mounted on the second lower pressing plate 1001 and used for abutting against the cloth; with such a structure, the cloth can be pressed by the first pressing wheel, so that the cloth can be pressed simultaneously when the cloth is cut longitudinally, thereby further improving the reliability of pressing the cloth for cutting.

[0041] It should be noted that the first cloth pressing device 19 can also be replaced by the second cloth pressing device 100 .

[0042] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
