Description

TECHNICAL FIELD

[0001] The present application relates to the field of diaphragm production, and particularly relates to a unwinding device and diaphragm production equipment. BACKGROUND

[0002] In the prior art, the unwinding mechanism usually adopts an air inflation shaft as the unwinding shaft and is supported and fixed by double-sided vertical plates. Although this structure has good stability, the air inflation shaft needs to be disassembled as a whole when feeding and discharging, and since the air inflation shaft is heavy, manual operation has the risk of injury, and the disassembly process takes a long time, affecting production efficiency and increasing costs. In addition, when the installation height of the unwinding mechanism is high, the feeding operation of the double-sided vertical plate support structure is extremely inconvenient. To solve this problem, the prior art proposes a single cantilever support structure, that is, the air inflation shaft is fixed by a single-sided support seat, and the other side is suspended, thereby simplifying the feeding and discharging operation. However, since the material roll is heavy, the air inflation shaft bears single-sided pressure for a long time, which easily causes deformation of the support structure, reduces transmission efficiency, and affects the stability of equipment operation. The existing improvement scheme mainly alleviates the deformation problem by enhancing the material or increasing the structural strength, but it cannot fundamentally solve the mechanical defects of the single cantilever structure, and increases the manufacturing cost.

[0044] The unwinding shaft needs to be removed when it is necessary to feed or discharge. In order to facilitate feeding or discharging, the existing unwinding shaft is supported by a single cantilever, one side is fixed and the other side is suspended, thereby simplifying the feeding or discharging operation. However, due to the single-sided support of the unwinding shaft, deformation is easy to occur after a long time, thereby affecting the stability of the equipment. Therefore, during unwinding, the suspended side of the unwinding shaft 200 is supported by the supporting arm 400, thereby preventing deformation and affecting the operation of the equipment during long-term use.

[0045] Referring to Figure 1 The embodiment of the present application provides an unwinding device, which comprises a mounting frame 100, an unwinding shaft 200, a rotary driving member 300, a supporting arm 400 and a swing driving assembly 500.

[0046] In some embodiments, the mounting frame 100 has a containing space, the unwinding shaft 200 is rotatably mounted on the mounting frame 100, and the unwinding shaft 200 is located in the containing space. The rotary driving member 300 is fixedly mounted on the mounting frame 100, and the rotary driving member 300 is in transmission connection with the unwinding shaft 200. The rotary driving member 300 is used for driving the unwinding shaft 200 to rotate. The supporting arm 400 is rotatably mounted on the mounting frame 100, and the supporting arm 400 is provided with a containing groove 410. The end of the unwinding shaft 200 away from the rotary driving member 300 is located in the containing groove 410. The swing driving assembly 500 is arranged on the mounting frame 100, and the swing driving assembly 500 is in transmission connection with the supporting arm 400. The swing driving assembly 500 is used for driving the supporting arm 400 to rotate.

[0047] Referring toFigure 1 As shown, the unwinding shaft 200 is rotatably installed on the inner side wall of the accommodating space, and the outer wall side of the mounting frame 100 is fixedly installed with a rotary driving member 300, the rotary end of the rotary driving member 300 is in transmission connection with the unwinding shaft 200, so as to drive the winding material on the outer circumferential surface of the unwinding shaft 200 to rotate, and realize unwinding. In the process of rotating the unwinding shaft 200, in order to prevent the deformation of the suspended side of the unwinding shaft 200 from affecting the operation of the equipment, a supporting arm 400 is arranged on the suspended side of the unwinding shaft 200, so that the end of the suspended side of the unwinding shaft 200 is located in the accommodating groove 410 of the supporting arm 400, and the supporting arm 400 supports the suspended side of the unwinding shaft 200. Further, when feeding or discharging is needed, the supporting arm 400 is only needed to be rotated by the swing driving assembly 500 to drive the end of the suspended side of the unwinding shaft 200 to be separated from the accommodating groove 410, so as to facilitate subsequent feeding or discharging. That is, the unwinding shaft 200 is supported by the supporting arm 400 during use, and the unwinding shaft 200 is separated from the accommodating groove 410 by rotating the supporting arm 400 by a certain angle when not in use, so as to facilitate feeding or discharging.

[0048] Further, in order to have sufficient torque to drive the unwinding shaft 200 and the winding material thereon, the rotary end of the rotary driving member 300 can be connected with a speed reducer, and the output shaft of the speed reducer is connected with the unwinding shaft 200. The type of the speed reducer can be selected from a planetary speed reducer, a helical gear speed reducer, a spur gear speed reducer, etc., and the speed reduction ratio of the speed reducer can be designed and selected according to actual needs, which is not limited here.

[0049] Further, in order to facilitate the rotation of the unwinding shaft 200, a bearing (not shown in the figure) should be installed on the outer circumferential surface of the end of the suspended side of the unwinding shaft 200. The inner ring of the bearing is installed with the unwinding shaft 200, and the outer ring of the bearing is in contact with the inner wall of the accommodating groove 410. Therefore, the supporting arm 400 supports the unwinding shaft 200 while not affecting the rotation of the unwinding shaft 200. As for the selection of the type of bearing, since the unwinding shaft 200 is only subjected to radial force, an angular contact ball bearing can be selected. The diameter of the inner ring of the bearing can be selected according to the diameter of the unwinding shaft 200. Similarly, the size of the outer ring can be selected according to the size of the accommodating groove 410.

[0050] In the embodiment, the cross section of the accommodating groove 410 is semicircular, and the diameter of the accommodating groove 410 should be greater than the diameter of the unwinding shaft 200, so as to accommodate the unwinding shaft 200.

[0051] In the embodiment, the mounting rack 100 comprises a first vertical plate 110, a second vertical plate 120 and at least one connecting rod 130, wherein the second vertical plate 120 is located at one side of the first vertical plate 110, the first vertical plate 110 and the second vertical plate 120 are arranged in parallel, the first vertical plate 110 and the second vertical plate 120 define a containing space, the connecting rod 130 is located in the containing space, one end of the connecting rod 130 is fixedly connected with the first vertical plate 110, and the end of the connecting rod 130 away from the first vertical plate 110 is fixedly connected with the second vertical plate 120.

[0052] Please continue to refer to Figure 1 As shown in the figure, the first vertical plate 110 and the second vertical plate 120 are arranged in parallel, and the first vertical plate 110 and the second vertical plate 120 are composed by the at least one connecting rod 130, so that the first vertical plate 110, the second vertical plate 120 and the connecting rod 130 form a stable mounting rack structure, and the whole frame is more stable. It can be understood that the space between the first vertical plate 110 and the second vertical plate 120 is a containing space, the unwinding shaft 200 is rotatably installed on the side of the first vertical plate 110 located in the containing space, and the rotary driving member 300 is installed on the side of the first vertical plate 110 away from the containing space, and the rotary driving member 300 drives the unwinding shaft 200 to rotate.

[0053] Further, the supporting arm 400 is rotatably installed on the outer side of the second vertical plate 120, and the swing driving assembly 500 is also installed on the outer side of the second vertical plate 120 on the same side as the supporting arm 400. The swing driving assembly 500 drives the supporting arm 400 to rotate to place the suspended end of the unwinding shaft 200 in the containing groove 410.

[0054] As Figure 1 shown, in order to facilitate the feeding and discharging of the unwinding shaft 200, the second vertical plate 120 can be arranged in an "L" shape, so as to prevent the second vertical plate 120 from interfering with the unwinding shaft 200 during feeding and discharging.

[0055] The swing driving assembly 500 comprises a guide rail 510, a sliding block 520, a connecting rod 530 and a first linear driving member 540, wherein the sliding block 520 is slidably installed on the guide rail 510, one end of the connecting rod 530 is rotatably installed on the sliding block 520, the end of the connecting rod 530 away from the sliding block 520 is rotatably connected with the supporting arm 400, and the driving end of the first linear driving member 540 is connected with the sliding block 520. The first linear driving member 540 is used to drive the sliding block 520 to move along the guide rail 510.

[0056] Please refer to Figure 1 , Figure 4 and Figure 5As shown, when it is needed to drive the supporting arm 400 to rotate by a certain angle, for example, it is needed to drive the supporting arm 400 to rotate to make the end of the unwinding shaft 200 on the side of the suspension to be separated from the containing groove 410, first, the first linear driving element 540 is started to drive the sliding block 520 to move along the guide rail 510 in the guide direction, the position of the sliding block 520 is changed, and then the inclination angle of the connecting rod 530 is changed, and then the supporting arm 400 is driven to rotate by the sliding block 520, so that the unwinding shaft 200 is separated from the containing groove 410, thereby facilitating the feeding and discharging of the unwinding shaft 200. Similarly, when it is needed to make the unwinding shaft 200 extend into the containing groove 410, it is only needed to drive the sliding block 520 to move along the guide rail 510 by the first linear driving element 540, so that the supporting arm 400 is rotated, the supporting arm 400 is rotated towards the direction of the unwinding shaft 200, the containing groove 410 is moved to the position of the end of the unwinding shaft 200, so that the unwinding shaft 200 is located in the containing groove 410, and the inner wall of the containing groove 410 is in contact with the outer ring of the bearing on the outer surface of the unwinding shaft 200 to support.

[0057] In the embodiment, the first linear driving element 540 can be selected from a linear driving element such as a pneumatic cylinder, an oil cylinder and an electric cylinder, and the specific type is not limited here.

[0058] Please continue to refer to Figure 1 , Figure 4 and Figure 5 As shown, a buffer 900 is arranged on the rotating path of the supporting arm 400, in order to prevent the supporting arm 400 from being stuck when it is rotated by a certain angle, a buffer 900 is arranged on the rotating path of the supporting arm 400, the supporting arm 400 is blocked by the buffer 900, so that it cannot be rotated to the maximum angle to cause the stuck phenomenon under the premise of meeting the requirement of removing the support of the unwinding shaft 200. Further, the buffer 900 is fixedly installed on the outer wall of the second vertical plate 120, and the buffer 900 can be selected from a hydraulic buffer or a pneumatic buffer, and the specific type and model can be selected according to actual needs, and the specific type is not limited here.

[0059] The unwinding device further comprises a machine table, the first vertical plate 110 and the second vertical plate 120 are slidably arranged on the machine table, the second linear driving element 600 is installed on the machine table, and the power output end of the second linear driving element 600 is connected with the first vertical plate 110 or the second vertical plate 120.

[0060] Please refer to Figure 2 and Figure 3As shown, when the rotating driving member 300 drives the unwinding shaft 200 to rotate for unwinding, if the position of the roll material deviates at this time, the roll material on the unwinding shaft 200 needs to be moved to correct the deviation, and the entire mounting frame 100 needs to be moved to correct the deviation of the roll material. Specifically, the mounting frame 100 is slidably installed on the machine table (not marked in the figure), and then the mounting frame 100 is moved by the second linear driving member 600 to achieve movement.

[0061] In one embodiment, the first vertical plate 110 and the second vertical plate 120 are slidably connected to the machine table by guide rail sliders, and the second linear driving member 600 is installed on the machine table. The driving direction of the second linear driving member 600 is perpendicular to the vertical direction of the first vertical plate 110 and the second vertical plate 120. The driving end of the second linear driving member 600 can be directly connected to the first vertical plate 110 or connected to the second vertical plate 120. In this embodiment, the driving end of the second linear driving member 600 is connected to the first vertical plate 110. The specific connection is not limited here and can be connected by hinging or bolt fixing.

[0062] It should be noted that the second linear driving member 600 can be a cylinder, an oil cylinder, or an electric cylinder under the condition of satisfying the accuracy adjustment.

[0063] The first vertical plate 110 is fixedly installed with a roll diameter detection assembly 700, which is located in the accommodation space. The roll diameter detection assembly 700 includes a mounting rod 710 fixedly installed on the first vertical plate 110, and a roll diameter detection sensor 720 fixedly installed on the mounting rod 710.

[0064] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the roll diameter detection assembly 700 is arranged on one side of the unwinding shaft 200 in the radial direction. The roll diameter detection assembly 700 is used to monitor the diameter of the roll material on the outer surface of the unwinding shaft 200 in real time, so as to determine whether the roll material is unwound and whether it needs to be replaced.

[0065] In one embodiment, the roll diameter detection assembly 700 includes a mounting rod 710 and a roll diameter detection sensor 720. The mounting rod 710 can be connected to the first vertical plate 110 or the second vertical plate 120, and then the mounting rod 710 extends into the accommodation space on one side of the unwinding shaft 200 in the radial direction. Then the roll diameter detection sensor 720 is installed on the mounting rod 710. The roll diameter detection sensor 720 is used to monitor the diameter of the roll material. It can be understood that the distance between the roll diameter detection sensor 720 and the outer surface of the unwinding shaft 200 should be greater than the thickness of the roll material, so that the roll diameter detection sensor 720 does not affect the unwinding of the roll material.

[0066] It should be noted that the roll diameter detection sensor 720 is a prior art element, and the detection of the roll thickness will not be described in detail here.

[0067] The locking assembly 800 is fixedly installed on the support arm 400, and the locking assembly 800 comprises a third linear drive 810 fixedly installed on the support arm 400. The driving end of the third linear drive 810 is provided with a locking block 820. The third linear drive 810 is used to drive the locking block 820 to extend into or away from the accommodating groove 410.

[0068] As shown in Figure 1 , Figure 4 and Figure 5 , when the end of the unwinding shaft 200 rotates in the accommodating groove 410, if the rotation speed is too fast, it is easy to appear jitter, thereby affecting the unwinding. Therefore, when the end of the unwinding shaft 200 is located in the accommodating groove 410, the outer surface of the bearing is fixed and locked by the locking assembly 800 to prevent jitter during rotation and affect the unwinding.

[0069] Specifically, the third linear drive 810 is arranged on the support arm 400 on the radial direction side of the accommodating groove 410. The driving end of the third linear drive 810 is fixedly installed with the locking block 820 matched with the bearing outer ring of the end surface of the unwinding shaft 200. When the third linear drive 810 drives the locking block 820 to move towards the inside of the accommodating groove 410, the locking block 820 abuts against the bearing outer ring, thereby fixing the bearing and the end of the unwinding shaft 200. Similarly, when it is not necessary to limit the position of the unwinding shaft 200, the locking block 820 only needs to be moved away from the accommodating groove 410 by the third linear drive 810.

[0070] The accommodating space is also provided with a tape connecting assembly 1000. The tape connecting assembly 1000 comprises a carrier plate 1010 fixedly connected with the first vertical plate 110 and the second vertical plate 120. The carrier plate 1010 is fixedly provided with a fourth linear drive 1020. The driving end of the fourth linear drive 1020 penetrates through the carrier plate 1010 to the other side of the carrier plate 1010. The driving end of the fourth linear drive 1020 is fixedly provided with a pressing plate 1030. The pressing plate 1030 and the carrier plate 1010 define a predetermined distance therebetween.

[0071] As shown in Figure 2 and Figure 6 , when the last roll of material is used up and a new roll of material is updated, it is necessary to connect the two roll heads and tails to enable normal unwinding. Specifically, after the last roll of material is used up, the two rolls are connected at the position of the pressing plate 1030. Specifically, the fourth linear drive 1020 drives the pressing plate 1030 to press downward to connect the two roll heads and tails located below the pressing plate 1030. Specifically, the pressing plate 1030 can be connected to the roll tape by hot pressing.

[0072] It should be noted that, since the coil material is unwound, the coil belt needs to pass between the pressing plate 1030 and the carrier plate 1010, so in the initial state, the preset distance between the pressing plate 1030 and the carrier plate 1010 should be much greater than the thickness of the coil belt, to prevent the upper surface of the coil belt from contacting the pressing plate 1030 and to prevent the lower surface of the coil belt from contacting the carrier plate 1010.

[0073] At least one first passing roller 1100 is arranged in the accommodation space, and the first passing roller 1100 is rotationally connected with the first vertical plate 110 and the second vertical plate 120.

[0074] Please refer to Figure 2 As shown in the figure, in order to enable the coil belt to pass between the pressing plate 1030 and the carrier plate 1010, it is necessary to arrange the first passing roller 1100 on both sides of the carrier plate 1010 for guiding, and the first passing roller 1100 is rotationally connected with the first vertical plate 110 and the second vertical plate 120.

[0075] Further, in order to change the discharge direction of the coil belt, a second passing roller 1200 can be installed on the machine table for guiding, and the installation position of the second passing roller 1200 can be set as needed, which is not limited here.

[0076] The embodiment of the present application also provides a membrane production device, and the membrane production device comprises the unwinding device.
