Flanging machine

Abstract

The utility model discloses a flanging machine which comprises a machine frame, a first bonding mechanism and a second bonding mechanism, and the first bonding mechanism is movably arranged on the machine frame in the vertical direction. The second bonding mechanism is arranged on the rack and opposite to the first bonding mechanism so as to jointly form a material passing gap. Due to the fact that the first bonding mechanism can move along the machine frame in the vertical direction, when a high object to be sewn passes through the material passing gap, the first bonding mechanism moves upwards under the action of the high object to be sewn, and the height of the material passing gap is increased to be matched with the height of the object to be sewn. Therefore, the friction force between the first bonding mechanism and the high to-be-sewn object can be reduced, the first bonding mechanism can work normally, and the working reliability of the flanging machine is improved.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1 As shown, in one embodiment, a folding machine 10 is provided, which includes a frame 1, a first bonding mechanism 2 and a second bonding mechanism 3. The first bonding mechanism 2 is movably arranged on the frame 1 in a vertical direction; the second bonding mechanism 3 is arranged on the frame 1 and relative to the first bonding mechanism 2 to jointly form a material transfer gap.

[0036] Since the first bonding mechanism 2 can move along the frame 1 in the vertical direction, when a higher object to be sewn passes through the feeding gap, the first bonding mechanism 2 moves upward under the action of the higher object to be sewn, so that the height of the feeding gap becomes larger to adapt to the height of the object to be sewn. Therefore, the friction between the first bonding mechanism 2 and the higher object to be sewn can be reduced, so that the first bonding mechanism 2 can work normally, thereby improving the reliability of the folding machine 10.

[0037] like Figure 1-2 As shown, the first bonding mechanism 2 includes a driving member 21, a driving wheel 22, two driven wheels 23, a transmission heat transfer belt 24, a heating member 25 and a sliding assembly 26. The driving member 21 is arranged on the frame 1, the driving member 21 is connected to the driving wheel 22, the two driven wheels 23 are respectively arranged on the heating member 25, the transmission heat transfer belt 24 is sleeved on the driven wheel 23 and the two driven wheels 23, the heating member 25 is connected to the sliding assembly 26, and the sliding assembly 26 is movably arranged on the frame 1 in the vertical direction. In the process of the higher object to be sewn passing through the feeding gap, the higher object to be sewn first passes through the driven wheel 23 on one side. When passing through, the higher object to be sewn first lifts up the driven wheel 23 on one side. After the higher object to be sewn passes through the driven wheel 23 on one side, the higher object to be sewn passes through the heating element 25 again. When passing through, the higher object to be sewn lifts up the heating element 25. At this time, the heating element 25 moves upward along the frame 1 in the vertical direction through the sliding assembly 26, so that the height of the feeding gap becomes larger to adapt to the height of the object to be sewn, thereby reducing the friction between the transmission heat transfer belt 24 and the higher object to be sewn, so that the transmission heat transfer belt 24 can drive the driving wheel 22 and the two driven wheels 23 to move, thereby improving the reliability of the folding machine 10.

[0038] In this embodiment, the driving wheel 22 is disposed close to the left driven wheel 23 and its projection in the vertical direction is located between the two driven wheels 23 .

[0039] The sliding assembly 26 includes a cylinder 261, a first slider 262 and a first slide rail 263. The cylinder 261 and the first slider 262 are respectively arranged on the frame 1. The first slide rail 263 is slidably arranged on the first slider 262 in the vertical direction. One end of the first slide rail 263 is connected to the piston rod of the heating element 25 and the cylinder 261 respectively. Specifically, when a higher object to be sewn passes through the heating element 25, the higher object to be sewn lifts the heating element 25, and the heating element 25 moves upward along the first slider 262 in the vertical direction through the first slide rail 263, so that the first slide rail 263 drives the piston rod of the cylinder 261 to move inward. It can be understood that the heating element 25 has a certain weight, so that the cylinder 261 has the function of a car suspension under the action of the heating element 25, so that the first bonding mechanism 2 can adapt to objects to be sewn of different heights.

[0040] In this embodiment, the sliding assembly 26 further includes a first connecting member 264 and a second connecting member 265 , and the first slide rail 263 and the heating member 25 are connected via the first connecting member 264 and the second connecting member 265 .

[0041] like Figure 2-4 As shown, the folding machine 10 also includes a tensioning mechanism 4, which is arranged on the frame 1 and is used to tension the transmission heat transfer belt 24. The tensioning mechanism 4 can adjust the tension of the transmission heat transfer belt 24, so that the transmission heat transfer belt 24 can always maintain a tensioned state, thereby improving the working stability of the transmission heat transfer belt 24.

[0042] The tensioning mechanism 4 includes a tensioning assembly 41 and a tensioning wheel 42. The tensioning assembly 41 is movably arranged on the frame 1 in the horizontal direction. The tensioning wheel 42 is located outside the transmission heat transfer belt 24 and is arranged adjacent to the driving wheel 22. The driving wheel 22 is arranged adjacent to one of the driven wheels 23. With such an arrangement, when the transmission heat transfer belt 24 needs to be disassembled, it is only necessary to move the tensioning assembly 41 in the horizontal direction, which is simple and convenient, thereby improving the efficiency of disassembling the transmission heat transfer belt 24.

[0043] The tensioning assembly 41 includes a second slider 411, a second slide rail 412, and an elastic member 413. The second slider 411 is disposed on the frame 1. The second slide rail 412 is slidably disposed on the second slider 411 in the horizontal direction. The tensioning wheel 42 is disposed on the second slide rail 412. One end of the elastic member 413 is connected to one end of the second slide rail 412, and the other end is connected to the frame 1. When the transmission heat transfer belt 24 needs to be disassembled, the second slide rail 412 is pressed so that the second slide rail 412 squeezes the elastic member 413, so that the second slide rail 412 can drive the tensioning wheel 42 to move toward the heating member 25, so that the tensioning force of the transmission heat transfer belt 24 becomes smaller, thereby quickly disassembling the transmission heat transfer belt 24.

[0044] In this embodiment, the tensioning assembly 41 further includes a third connecting member 414 , and one end of the elastic member 413 and one end of the second slide rail 412 are connected via the third connecting member 414 .

[0045] The top of the second slide rail 412 is flush with the top of the heating element 25. With such a configuration, when the heating element 25 moves upward, the tension of the transmission heat transfer belt 24 decreases. At this time, the elastic element 413 drives the second slide rail 412 to move under the action of the restoring force, so that the second slide rail 412 drives the tensioning wheel 42 to move toward the end away from the heating element 25 to tighten the transmission heat transfer belt 24; when the heating element 25 moves downward, the tension of the transmission heat transfer belt 24 increases. At this time, the transmission heat transfer belt 24 drives the second slide rail 412 to move toward the end away from the frame 1 through the tensioning wheel 42. Since the top of the second slide rail 412 is flush with the top of the heating element 25, when the heating element 25 moves up and down, the transmission heat transfer belt 24 can always be in contact with the heating element 25, so the heat of the heating element 25 can be reliably transferred to the transmission heat transfer belt 24, thereby ensuring the reliability of the folding of the folding machine 10.

[0046] An escape groove 251 is provided at one end of the heating element 25 adjacent to the second slide rail 412 to avoid the tension wheel 42. When the heating element 25 moves upward, the tension wheel 42 can be avoided through the escape groove 251, so that the transmission heat transfer belt 24 in contact with the tension wheel 42 can move reliably, thereby ensuring the reliability of the folding machine 10.

[0047] like Figure 3-4 As shown, the folding machine 10 also includes a correction mechanism 5, which is used to correct one or two of the two driven wheels 23 so that the transmission heat transfer belt 24 is located in the middle of the two driven wheels 23, so that the transmission heat transfer belt 24 can drive the driving wheel 22 and the two driven wheels 23 to move reliably, thereby ensuring the reliability of the folding machine 10.

[0048] The deviation correction mechanism 5 includes a deviation correction member 51 and a supporting member 52. The deviation correction member 51 is arranged on the frame 1. The rotating shaft of the driven wheel 23 is arranged on the deviation correction member 51. The supporting member 52 supports the rotating shaft of the driven wheel 23. By tightening or loosening the supporting member 52, the deviation correction member 51 is deformed, thereby adjusting the distance between the driven wheel 23 and the frame 1. When the transmission heat transfer belt 24 deviates outward, the supporting member 52 is tightened to straighten the deviation correction member 51, so that the distance between the driven wheel 23 and the frame 1 increases, so that the transmission heat transfer belt 24 moves inward to the middle position of the two driven wheels 23. When the transmission heat transfer belt 24 deviates inward, the supporting member 52 is loosened to bend the deviation correction member 51, so that the distance between the driven wheel 23 and the frame 1 decreases, so that the transmission heat transfer belt 24 moves outward to the middle position of the two driven wheels 23.

[0049] It can be understood that in this embodiment, the second bonding mechanism 3 is substantially the same except that it does not have the sliding component 26 . Therefore, the second bonding mechanism 3 may refer to the first bonding mechanism 2 , and will not be described in detail herein.

[0050] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
