Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding machines, in particular to a folding bag welding machine. Background Art
[0002] In the prior art, pocket production requires the use of an ultrasonic plastic welding machine for edge sealing; specifically, the principle of ultrasonic plastic welding is that a generator generates a high-voltage, high-frequency signal, which is converted into a high-frequency mechanical vibration through a transducer system and applied to the pocket workpiece. The temperature transmitted to the interface is increased through the friction between the pocket surface and the molecules. When the temperature reaches the melting point of the workpiece itself, the pocket interface melts rapidly and then fills the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, thus achieving high-quality welding.
[0003] However, the inventor discovered during production that when making some larger pockets, two operators were required to manually fold the two connecting edges of the pockets in half and then feed them into a welding machine for edge sealing. This operation method lacks positioning of the connecting edges, and errors are prone to occur during edge sealing welding, resulting in uneven connecting edges of the welded pockets and incorrect welding positions, which seriously affects the welding yield.
[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0045] 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.
[0046] Please also read Figures 1 to 7 The folding bag welding machine 10 provided in the embodiment of the present application is now described. The folding bag welding machine 10 comprises: a frame 11, a workbench 12, a first positioning plate 13, a first folding mechanism 14, a second folding mechanism 15 and a welding device 16.
[0047] The workbench 12 is installed on the frame 11 for carrying the cloth 20; the first positioning plate 13 is installed on the frame 11 for positioning the cloth 20 fed into the workbench 12; the first folding mechanism 14 is installed on the frame 11 for performing the first folding on the cloth 20 fed into the workbench 12; the second folding mechanism 15 is installed on the frame 11 for performing the second folding on the cloth 20 that has completed the first folding, and using the first folding and the second folding to enclose the pocket; the welding device 16 is installed on the frame 11 for welding the first folding and the second folding plate 152 formed by the first folding and the second folding to complete the welding production of a pocket.
[0048] Specifically, by setting up the first positioning plate 13, the pocket fed into the workbench 12 can be positioned. After positioning, the first folding mechanism 14 and the second folding mechanism 15 are used in turn to enclose the pocket, and then the two folded edges are welded by the welding device 16 to complete the production of a pocket. In this process, there is no need to manually fold the pocket fabric 20 in half, which reduces the labor intensity of the operation function. At the same time, the first positioning plate 13 can be used to complete precise positioning, and the subsequent first and second folding edges do not require manual operation, which can improve the folding accuracy, thereby improving the pocket welding yield.
[0049] During operation, first adjust the position of the first positioning plate 13 relative to the first notch 121 to change the size of the first folded edge and the second folded edge; then feed the cloth 20 into the workbench 12, so that the end of the cloth 20 is against the first positioning plate 13; then, start the first folding mechanism 14 to perform the first folding on the cloth 20; then, start the second folding mechanism 15 to perform the second folding on the cloth 20; at this time, the first folded edge formed by the first folding and the second folded edge formed by the second folding can overlap up and down; finally, use the welding device 16 to weld the first folded edge and the second folded edge that overlap up and down to make a pocket.
[0050] In some embodiments of the present application, the workbench 12 is provided with a first notch 121 , and the first folding mechanism 14 is located above the workbench 12 ; when the first folding mechanism 14 folds down the cloth 20 , the cloth 20 can be pushed into the first notch 121 .
[0051] Specifically, the first folding mechanism 14 includes a first cylinder 141 and a first folding plate 142. The first cylinder 141 is installed on the frame 11 and is located above the workbench 12; the first folding plate 142 is installed on the telescopic rod of the first cylinder 141; when the telescopic rod of the first cylinder 141 is extended, the first folding plate 142 moves toward the first notch 121 to push the cloth 20 into the first notch 121.
[0052] In some embodiments of the present application, the second folding mechanism 15 includes a second cylinder 151 and a second folding plate 152, the second cylinder 151 is installed on the frame 11, and the second folding plate 152 is installed on the telescopic rod of the second cylinder 151; and the second folding plate 152 is parallel to the workbench 12 and is located behind the first notch 121; when the telescopic rod of the second cylinder 151 is extended, the second folding plate 152 can move forward to push the cloth 20 to fold the edges for the second time to form a pocket. The first positioning plate 13 can be movably installed on the top of the workbench 12 and is located behind the first notch 121, so that the workbench 12, the first positioning plate 13 and the second folding plate 152 are stacked from bottom to top.
[0053] It should be noted here that, in some other embodiments of the present application, when bending a large cloth 20, a second folding plate 152 with a very long length is required, and therefore a plurality of second cylinders 151 need to be arranged. The plurality of second cylinders 151 are spaced apart along the extension direction of the second folding plate 152 and installed on the frame 11. The plurality of second cylinders 151 can be extended and retracted at the same time to drive the longer second folding plate 152 to move downward to complete the first folding operation. Such a structure can enhance the reliability of the second folding plate 152 when moving downward, obtain a more balanced downward force, and improve the reliability of the folding operation.
[0054] In more detail, the welding device 16 includes a first welding rod 161, a third cylinder 162 and a second welding rod 163; the first welding rod 161 is fixedly mounted on the frame 11 and is located in front of the first notch 121; the third cylinder 162 is mounted on the frame 11 and is located above the workbench 12; the second welding rod 163 is mounted on the telescopic rod of the third cylinder 162, and when the telescopic rod of the third cylinder 162 is extended, the second welding rod 163 can be displaced toward the first welding rod 161 to weld the folded edges together.
[0055] It can be understood that, when making large pockets, longer first welding rods 161 and second welding rods 163 are required for welding; therefore, the welding device 16 also includes a first welding support frame 165 and a second welding support frame 166. The first welding support frame 165 is fixedly installed on the frame 11 and is located in front of the first notch 121. The first welding rod 161 is carried on the top of the first welding support frame 165; the second welding support frame 166 is installed on the telescopic rod of the third cylinder 162, and the second welding rod 163 is carried on the bottom of the second welding support frame 166; since the second welding support frame 166 is very long, a plurality of third cylinders 162 are provided to simultaneously drive the second welding support frame 166 to move up and down; such a structure can ensure that the pressure is in a balanced state during welding, thereby improving the welding yield.
[0056] Preferably, tensioning wheels 164 are provided at both ends of the first welding rod 161 and the second welding rod 163 , and the tensioning wheels 164 are used to tighten the first welding rod 161 and the second welding rod 163 respectively.
[0057] In more detail, the top of the first welding rod 161 is arranged flush with the top of the workbench 12, so as to smoothly feed the cloth 20 into the workbench 12 and allow the end of the cloth 20 to rest against the first positioning plate 13, thereby reducing the problem of jamming during the feeding process and improving the positioning accuracy of the cloth 20 and the feeding reliability.
[0058] In other embodiments of the present application, the frame 11 is also provided with a edge clamping mechanism 17, which includes a fourth cylinder 171 and a fourth pressure plate 172. The fourth cylinder 171 is installed on the frame 11 and is located above the workbench 12 and in front of the welding device 16; the fourth pressure plate 172 is installed on the telescopic rod of the fourth cylinder 171; when the telescopic rod of the fourth cylinder 171 is extended, the fourth pressure plate 172 can be moved toward the workbench 12 to tighten the folded edge.
[0059] Specifically, after the cloth 20 completes the first folding and the second folding, a first folding and a second folding 22 will be formed, and the first folding and the second folding 22 will be welded together by the welding device 16; in order to ensure the reliable welding of the first folding and the second folding 22, before welding, the fourth pressure plate 172 is driven downward by the fourth cylinder 171 to press the first folding and the second folding 22, and then the first welding rod 161 and the second welding rod 163 are used to press the first folding and the second folding 22, and the first welding rod 161 and the second welding rod 163 are heated to weld the first folding and the second folding 22 together.
[0060] In some embodiments of the present application, in order to improve the reliability and safety of the folding bag welding machine 10 provided in the present application, the workbench 12 is provided with a sensing device 18 in front of the edge pressing mechanism 17, which can sense whether the material 20 is in the feeding state when feeding the material 20; when an external object triggers the sensing device 18, the folding bag welding machine 10 is in the shutdown state. Of course, the height of the installation of the sensing device 18 must be higher than the thickness of the material 20.
[0061] Please also read Figures 5 to 7 The working process of the folding bag welding machine 10 provided by the present application is described in detail as follows:
[0062] First, provide the cloth 20, and adjust the displacement distance of the first positioning plate 13 relative to the first notch 121 according to the required pocket size;
[0063] Then, the cloth 20 is fed into the workbench 12, and one end of the cloth 20 is made to abut against the first positioning plate 13;
[0064] Furthermore, the first folding mechanism 14 is started, the telescopic rod of the first cylinder 141 is extended to drive the first folding plate 142 to move downward, and the cloth 20 is pressed into the first notch 121 to complete the first folding, and then the telescopic rod of the first cylinder 141 is retracted to drive the first folding plate 142 to move upward and reset;
[0065] Then, the second folding mechanism 15 is started, the telescopic rod of the second cylinder 151 is extended to drive the second folding plate 152 to move forward, and the cloth 20 is pushed forward to complete the second folding, and then the telescopic rod of the second cylinder 151 is retracted to drive the second folding plate 152 to move backward and reset; at this time, the first folding 21 and the second folding 22 formed by the first folding and the second folding are stacked up and down;
[0066] Furthermore, the edge pressing mechanism 17 is started, and the telescopic rod of the fourth cylinder 171 is extended to drive the fourth pressing plate 172 to move downward, pressing the first folding edge 21 and the second folding edge 22;
[0067] Then, the welding device 16 is started, and the telescopic rod of the third cylinder 162 is used to drive the second welding rod 163 to move downward, so that the first welding rod 161 and the second welding rod 163 can weld the first folded edge 21 and the second folded edge 22 together;
[0068] Finally, the telescopic rod of the fourth cylinder 171 retracts to drive the fourth pressing plate 172 to move upward, and the telescopic rod of the third cylinder 162 drives the second welding rod 163 to move upward, completing the reset to complete a pocket welding operation. The above steps are continuously repeated to continuously perform pocket welding operations.
