Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cutting equipment, specifically to an automatic cutting device for ion exchange membranes. Background Technology
[0002] Ion exchange membranes include perfluorinated ion exchange membranes, perfluorosulfonic acid ion exchange membranes, water electrolysis hydrogen production ion exchange membranes, vanadium battery ion exchange membranes, and chlor-alkali ion exchange membranes. Perfluorinated ion exchange membranes are the core technical materials in exchange membrane fuel cells and the chlor-alkali industry.
[0003] Currently, when cutting ion exchange membranes, a cutter is typically used to cut the membrane in its width direction, thus completing the large-scale cutting into ion exchange membrane sheets of a certain specification. Throughout the cutting process, an unwinding mechanism is usually installed on the frame. The unwinding mechanism releases the ion exchange membrane while the cutter cuts it. To improve cutting efficiency, the unwinding mechanism is currently in a continuous state of releasing the ion exchange membrane, and the cutter can also continuously cut the ion exchange membrane. However, some cutters are currently in a straight up-down cutting mode, which makes it easy for the released ion exchange membrane to be obstructed by the cutter when being cut, resulting in problems such as curling or even wrinkles at the edges of some ion exchange membranes. Utility Model Content
[0004] The purpose of this invention is to provide an automatic cutting device for ion exchange membranes to address the shortcomings of the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cutting device for ion exchange membranes, comprising a frame and an unwinding roller rotatably connected to the frame, and a cutting mechanism for cutting the ion exchange membranes, the cutting mechanism comprising: a sliding frame slidably connected to the frame; a preset track formed on the frame, the preset track comprising a first inclined groove, a second inclined groove, and a transverse groove connected together, the first inclined groove, the second inclined groove, and the transverse groove being arranged in a triangular pattern; and a sliding column slidably connected within the preset track, the sliding column being fixedly connected to... The device includes a cutter that is vertically and elastically slidably connected to a sliding frame; a drive mechanism that drives the sliding frame to slide on the frame, causing the sliding column to move from the upper end to the lower end of the first inclined groove, so that the cutter slides vertically relative to the sliding frame to cut the released ion membrane; then, it drives the sliding column to move from the lower end to the upper end of the second inclined groove, so that the cutter slides vertically upward relative to the sliding frame; and then it drives the sliding column to slide along the transverse groove to the junction of the transverse groove and the first inclined groove; and a limiting member that is assembled to prevent the sliding column from moving from the first inclined groove into the transverse groove.
[0006] Preferably, the limiting member includes a limiting strip located at the junction of the horizontal groove and the first inclined groove and vertically slidably connected to the frame. The limiting strip has a first inclined surface and a second inclined surface, the first inclined surface facing the first inclined groove and the second inclined surface facing the horizontal groove. A first elastic element is provided between the limiting strip and the frame. The process of the first elastic element restoring its elastic deformation drives the limiting strip to move vertically upward.
[0007] Preferably, the driving mechanism includes a driving cylinder fixedly connected to the frame, and the telescopic end of the driving cylinder is fixedly connected to the sliding frame via a connecting rod.
[0008] Preferably, the sliding frame has a vertical groove, and the cutter is fixedly connected to a connecting block located in the vertical groove. The connecting block is fixedly connected to the sliding column. The vertical groove is provided with a first elastic telescopic rod, one end of which is fixedly connected to the connecting block, and the other end is fixedly connected to the sliding frame.
[0009] Preferably, the process of the first elastic telescopic rod restoring its elastic deformation can drive the cutter to move vertically upward.
[0010] Preferably, the first elastic element includes a second elastic telescopic rod disposed on the frame, one end of the second elastic telescopic rod being fixedly connected to the frame, and the other end being fixedly connected to the limiting strip via a connecting rod.
[0011] Preferably, the frame has a slot for the connecting rod to slide vertically.
[0012] Preferably, the frame is provided with a first traction unit and a second traction unit for traction of the ion membrane along the direction of the unwinding release roller ion membrane; the first traction unit includes a first traction roller rotatably connected to the frame, and a first slide table located directly above the first traction roller is vertically elastically slidably connected to the frame, and a first flattening roller is rotatably connected to the first slide table; the first traction unit also includes a second traction roller rotatably connected to the frame, and a second slide table located directly above the second traction roller is vertically elastically slidably connected to the frame, and a second flattening roller is rotatably connected to the second slide table.
[0013] Preferably, a first spring is provided between the first slide and the frame, with one end of the first spring fixedly connected to the first slide and the other end fixedly connected to the frame.
[0014] Preferably, a second spring is provided between the second slide and the frame, with one end of the second spring fixedly connected to the second slide and the other end fixedly connected to the frame.
[0015] In the above technical solution, the present invention provides an automatic cutting device for ion exchange membranes. When the driving mechanism drives the sliding frame to slide relative to the machine frame, the sliding frame can push the sliding column to slide on the first inclined groove. That is, the sliding column moves from the upper end of the first inclined groove to the lower end of the first inclined groove. This allows the cutter, which is fixedly connected to the sliding column, to receive the drive of the sliding frame and make a horizontal movement while simultaneously sliding vertically relative to the sliding frame to cut the horizontally moving ion exchange membrane. The horizontal movement direction is along the direction of horizontal movement when the ion exchange membrane is released. This process allows the cutter to maintain the same speed as the ion exchange membrane while cutting it, thus eliminating the need for the unwinding roller to stop rotating during cutting, thereby improving work efficiency. At the same time, during the continuous unwinding process, the cutter will not squeeze the edge of the cut ion exchange membrane during normal cutting, thus avoiding wrinkles and curling at the edge of the ion exchange membrane and ensuring the quality of the ion exchange membrane. Similarly, when the sliding column moves from the lower end to the upper end of the second inclined groove, the cutter fixedly connected to the sliding column can simultaneously move horizontally under the drive of the sliding frame and slide vertically upward relative to the sliding frame, thus detaching from the horizontally moving ion membrane. Consequently, the cutter will not compress the edge of the cut ion membrane when detaching, thus preventing wrinkles and curling at the edge of the ion membrane. The limiting component allows the driving mechanism to move the sliding column from the first inclined groove into the transverse groove, without obstructing its movement along the transverse groove to the upper end of the first inclined groove.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] Please see Figure 1-7 This utility model provides an automatic cutting device for ion exchange membranes, including a frame 1 and an unwinding roller 2 rotatably connected to the frame 1. It also includes a cutting mechanism 3 for cutting the ion exchange membrane. The cutting mechanism 3 includes a sliding frame 31, a preset track 32, a sliding column 33, a driving mechanism 35, and a limiting member. The sliding frame 31 is slidably connected to the frame 1. The preset track 32 is formed on the frame 1 and includes a first inclined groove 321, a second inclined groove 322, and a transverse groove 323 connected together, arranged in a triangular pattern. The sliding column 33 is slidably connected within the preset track 32, and a fixed component is mounted on the sliding column 33. A cutter 34 is fixedly connected, and the cutter 34 is vertically elastically slidably connected to the sliding frame 31. During the sliding process of the sliding frame 31 on the frame 1, the drive mechanism 35 drives the sliding column 33 to move from the upper end of the first inclined groove 321 to the lower end, so that the cutter 34 slides vertically relative to the sliding frame 31 to cut the ion membrane being released. Then, the drive mechanism 35 drives the sliding column 33 to move from the lower end of the second inclined groove 322 to the upper end, so that the cutter 34 slides vertically upward relative to the sliding frame 31. Then, the drive mechanism 35 drives the sliding column 33 to slide along the transverse groove 323 to the junction of the transverse groove 323 and the first inclined groove 321. A limiting member is assembled to prevent the sliding column 33 from moving from the first inclined groove 321 into the transverse groove 323.
[0028] Specifically, when the drive mechanism 35 drives the sliding frame 31 to slide relative to the frame 1, the sliding frame 31 can push the sliding column 33 to slide on the first inclined groove 321. That is, the sliding column 33 moves from the upper end of the first inclined groove 321 to the lower end of the first inclined groove 321. This allows the cutter 34, which is fixedly connected to the sliding column 33, to receive the drive of the sliding frame 31 and move horizontally while sliding vertically relative to the sliding frame 31 to cut the horizontally moving ion membrane. The horizontal movement direction is along the direction of horizontal movement when the ion membrane is released. This process allows the cutter 34 to maintain the same speed as the ion membrane while cutting it, so that the unwinding roller 2 does not need to stop rotating during the cutting process, thereby improving work efficiency. At the same time, during the continuous unwinding process of the unwinding roller 2, the cutter 34 will not squeeze the edge of the cut ion membrane during normal cutting, thereby avoiding wrinkles and curling at the edge of the ion membrane and ensuring the quality of the ion membrane. Similarly, when the sliding column 33 moves from the lower end of the second inclined groove 322 to the upper end of the second inclined groove 322, the cutter 34, fixedly connected to the sliding column 33, can receive the drive of the sliding frame 31 to make a horizontal movement while simultaneously sliding vertically upward relative to the sliding frame 31 and detaching from the horizontally moving ion membrane. Thus, the cutter 34 will not squeeze the edge of the cut ion membrane when detaching, thereby preventing wrinkles and curling at the edge of the ion membrane. The limiting member allows the driving mechanism 35 to drive the sliding column 33 to move into the transverse groove 323 when sliding within the first inclined groove 321, without obstructing the sliding column 33 from sliding along the transverse groove 323 and moving to the upper end of the first inclined groove 321.
[0029] The limiting component includes a limiting strip 41 located at the junction of the transverse groove 323 and the first inclined groove 321 and vertically slidably connected to the frame 1. The limiting strip 41 has a first inclined surface 411 and a second inclined surface 412. The first inclined surface 411 faces the first inclined groove 321, and the second inclined surface 412 faces the transverse groove 323. A first elastic element 42 is provided between the limiting strip 41 and the frame 1. The process of the first elastic element 42 restoring its elastic deformation drives the limiting strip 41 to move vertically upward. The first elastic element 42 includes a second elastic telescopic rod provided on the frame 1. One end of the second elastic telescopic rod is fixedly connected to the frame 1, and the other end is fixedly connected to the limiting strip 41 via a connecting rod.
[0030] It should be noted that the frame 1 has a slot for the connecting rod to slide vertically. This facilitates the vertical sliding between the limiting strip 41 and the frame 1.
[0031] It should be noted that the slope of the first inclined surface 411 is preferably the same as the slope of the first inclined groove 321, so that the sliding can move better along the upper end of the first inclined groove 321 to the lower end of the first inclined groove 321.
[0032] Specifically, when the drive mechanism 35 drives the sliding frame 31 to move, the sliding frame 31 pushes the sliding column 33 to slide in the first inclined groove 321. Due to the setting of the first inclined surface 411 of the limiting strip 41, the limiting strip 41 prevents the sliding column 33 from moving from the first inclined groove 321 to the transverse groove 323, while also not affecting the sliding column 33 sliding along the first inclined groove 321. When the drive mechanism 35 drives the sliding column 33 to slide in the transverse groove 323, the sliding column 33 will squeeze the second inclined surface 412 of the limiting strip 41 to make the limiting strip 41 slide down relative to the frame 1. When the sliding column 33 moves past the limiting strip 41 to the upper end of the first inclined groove 321, the first elastic member 42, i.e. the second elastic telescopic rod, returns to its elastic deformation to make the limiting strip 41 return to its original position and slide upward, so that the limiting strip 41 can prevent the sliding column 33 from moving from the first inclined groove 321 to the transverse groove 323 next time.
[0033] The drive mechanism 35 includes a drive cylinder fixedly connected to the frame 1. The telescopic end of the drive cylinder is fixedly connected to the sliding frame 31 via a connecting rod. When the telescopic end of the drive cylinder extends, it drives the sliding column 33 to move sequentially along the first inclined groove 321 and the second inclined groove 322 to the junction of the upper inclined end of the second inclined groove 322 and the transverse groove 323. Then, when the telescopic end of the drive cylinder retracts, it causes the sliding column 33 to move within the transverse groove 323 and abut against the limiting strip 41, moving to the upper inclined end of the first inclined groove 321.
[0034] The sliding frame 31 has a vertical groove 5, and a connecting block 6 is fixedly connected to the cutter 34 within the vertical groove 5. The connecting block 6 is fixedly connected to the sliding column 33. A first elastic telescopic rod 7 is provided within the vertical groove 5, one end of which is fixedly connected to the connecting block 6, and the other end is fixedly connected to the sliding frame 31. It should be noted that the process of the first elastic telescopic rod 7 restoring its elastic deformation can drive the cutter 34 to move vertically upwards.
[0035] Specifically, when the sliding column 33 slides in the first inclined groove 321, the connecting block 6 slides vertically in the vertical groove 5 to make the cutter 34 slide vertically relative to the sliding frame 31 to cut the ion membrane; when the sliding column 33 slides in the second inclined groove 322, the connecting block 6 slides vertically upward in the vertical groove 5 to make the cutter 34 detach from the ion membrane; when the sliding column 33 is located at the junction of the upper end of the second inclined groove 322 and the transverse groove 323, the first elastic telescopic rod 7 can prevent the cutter 34 from falling, so that the sliding column 33 can move better along the transverse groove 323.
[0036] The frame 1 is provided with a first traction unit 8 and a second traction unit 9 sequentially arranged along the direction of the unwinding release roller ion membrane. The first traction unit 8 includes a first traction roller 81 rotatably connected to the frame 1, and a first slide 82 located directly above the first traction roller 81, vertically and elastically slidably connected to the frame 1. A first flattening roller 83 is rotatably connected to the first slide 82. The first traction unit 8 also includes a second traction roller 91 rotatably connected to the frame 1, and a second slide 92 located directly above the second traction roller 91, vertically and elastically slidably connected to the frame 1. A second flattening roller 93 is rotatably connected to the second slide 92. A first spring 84 is provided between the first slide 82 and the frame 1, with one end fixedly connected to the first slide 82 and the other end fixedly connected to the frame 1. Similarly, a second spring 94 is provided between the second slide 92 and the frame 1, with one end fixedly connected to the second slide 92 and the other end fixedly connected to the frame 1.
[0037] The frame 1 is fixedly connected to a first motor that drives the first traction roller 81, and the output shaft of the first motor is fixedly connected to the first traction roller 81 coaxially. Similarly, the frame 1 is fixedly connected to a second motor that drives the second traction roller 91, and the output shaft of the second motor is fixedly connected to the second traction roller 91 coaxially.
[0038] Specifically, the first spring 84 allows the first flattening roller 83 to move up and down, enabling the operator to pull the ion exchange membrane in the initial stage. Simultaneously, the elastic force of the first spring 84 forces the first flattening roller 83 downwards, flattening the ion exchange membrane between the first traction roller 81 and the first flattening roller 83, facilitating the subsequent cutting process by the cutting mechanism 3 and effectively reducing the probability of ion exchange membrane damage. Furthermore, the first traction roller 81, in conjunction with the first motor and the first flattening roller 83, can pull the ion exchange membrane for the subsequent cutting process by the cutting mechanism 3. Similarly, the second spring 94 allows the second flattening roller 93 to move up and down, enabling the operator to pull the ion exchange membrane in the initial stage. Simultaneously, the elastic force of the second spring 94 forces the second flattening roller 93 downwards, flattening the ion exchange membrane between the second traction roller 91 and the second flattening roller, further effectively reducing the probability of ion exchange membrane damage. Simultaneously, the second traction roller 91, in conjunction with the second motor and the second flattening roller 93, can pull the cut ion exchange membrane for subsequent collection by the operator.
[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
