Description

Technical Field

[0002] Membrane material is a material used in membrane structure engineering. It is a composite material composed of a high-strength fabric substrate and a polymer coating. The coating protects the substrate and forms the sealing performance of the membrane material. The production process of membrane materials generally includes the following steps: raw material melting, forming, cooling, film cutting and winding. Existing membrane materials are automatically wound on the winding rack. However, when the membrane material is wound to a single roll and is about to be wound, the operator needs to visually judge whether the diameter and thickness of the membrane material on the winding roller have reached the maximum winding diameter, whether the entire roll of membrane material has been wound and can be replaced with the next roll before winding. Then, the operator manually controls the shear knife to cut the membrane material. This will result in average cutting efficiency and requires the operator to concentrate on observing the winding situation of the membrane material on the winding roller, which is laborious and requires a lot of manual labor.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, an automatic cutting device for winding a film material 101 includes a workbench 2 and a work frame 3. The workbench 2 and the work frame 3 include, from left to right, a first conveying mechanism, an automatic cutting mechanism, a winding detection mechanism, and a winding mechanism. The work frame 3 includes two side panels 31 and a top panel 32.

[0024] The first conveying mechanism includes a first conveying roller 41 and a second conveying roller 42. The first conveying roller 41 is installed on the work frame 3, and the second conveying roller 42 is installed on the workbench 2. The film material 101 is located between the first conveying roller 41 and the second conveying roller 42. By setting the first conveying roller 41 and the second conveying roller 42, it is beneficial to automatically convey the film material 101 and facilitate transportation.

[0025] The winding mechanism includes a winding frame 51 and a winding roller 52. A second drive motor 53 is provided on one side of the winding frame 51. The winding roller 52 is connected to the output shaft of the second drive motor 53.

[0026] The winding detection mechanism includes a controller 61, a first mounting plate 62 symmetrically arranged on two side walls of the mounting frame, a first guide rail 63 symmetrically arranged on the side wall, a first driving assembly and a detection seat 64, a first lifting plate 66 is slidably arranged on the two first guide rails 63, a detection seat 64 is installed at the bottom of the first lifting plate 66, a protrusion 661 is installed on the first lifting plate 66, a first connecting seat 67 is provided at the bottom of the top plate 32, a first limiting groove 671 is provided on the first connecting seat 67, a pressure-sensitive sensor 672 is provided in the first limiting groove 671, the protrusion 661 enters the first limiting groove 671 of the first connecting seat 67 and abuts against the pressure-sensitive sensor 672, and the pressure-sensitive sensor 672 is connected to the controller 61 through an electric wire;

[0027] The automatic shearing mechanism includes a second lifting frame 71, a hydraulic cylinder 72, a second lifting plate 73 and a scissor seat 74. The second lifting frame 71 is installed below the top plate 32. Several hydraulic cylinders 72 are installed on the second lifting frame 71. The second lifting plate 73 is fixed to the bottom of the piston rod of the hydraulic cylinder 72. A scissor seat 74 is installed below the second lifting plate 73. The scissor seat 74 has a shearing knife group 75. The workbench 2 also has a base 76, and the base 76 also has a shearing groove 761 that cooperates with the shearing knife group 75.

[0028] In the present invention, the controller 61 and the pressure-sensitive sensor 672 are prior art.

[0029] With the above structure, a winding detection mechanism is added to the winding roller 52 of the winding frame 51, and the winding roller 52 is located below the detection seat 64 at the bottom of the first lifting plate 66. A sensor is provided at the bottom of the detection seat 64. When the winding roller 52 is wound to a certain diameter and abuts against the sensor at the bottom of the detection seat 64, the first driving component drives the first lifting plate 66 to move upward slowly according to the winding frequency of the winding roller 52. The first lifting plate 66 moves upward until the protrusion 661 on the first lifting plate 66 is lifted to abut against the pressure-sensitive sensor 672 in the first limiting groove 671 of the first connecting seat 67, and the protrusion 661 gives the pressure-sensitive sensor 672 upward. After the pressure 72 reaches a certain strength, the lifting height is the state where the rolled film 101 needs to be cut, and the pressure-sensitive sensor 672 transmits an electrical signal to the controller 61. The controller 61 receives this signal and automatically drives the hydraulic cylinder 72 on the second lifting frame 71 to move downward. At the same time, the shearing knife on the second lifting plate 73 moves downward to automatically cut the film 101 directly below. The setting of this device is conducive to automatically detecting and automatically cutting the film 101 when the rolled film 101 on the winding roller 52 is wound to the extent that it needs to be cut, which is conducive to being more convenient and quick, and the winding efficiency is higher. The film 101 is automatically cut after the winding is completed, which is more practical.

[0030] Specifically, if Figures 1 to 5 As shown, the first drive assembly includes a second drive motor 53 and a screw rod 652 . The second drive motor 53 is mounted on the top plate 32 of the workbench 3 . The second drive motor 53 is transmission-connected to the screw rod 652 , and the screw rod 652 is connected to the first lifting plate 66 .

[0031] With the above structure,

[0032] like Figures 1 to 5 As shown, a first detector 81 and a second detector 82 are respectively installed on the front and rear sides of the scissor seat 74 for detecting whether the film material 101 passes through.

[0033] In the present invention, the first detector 81 and the second detector 82 are prior art.

[0034] By setting the first detector 81 and the second detector, it is beneficial to detect in real time whether the film material 101 passes thereunder. If the film material 101 does not pass thereunder, the electrical signal is transmitted to the controller 61, which is beneficial to the subsequent automatic resetting of the winding state, plays the role of real-time detection, and facilitates observation.

[0035] like Figures 1 to 5As shown, the base 76 is further provided with third conveying rollers 83 at the same height as the shearing groove 761, located on the left and right sides of the shearing groove 761. By providing the third conveying rollers 83, the highest position of the third conveying rollers 83 is flush with the highest position of the shearing groove 761, so that the film material 101 does not wrinkle when passing through the shearing groove 761, and the film material 101 is conveniently and quickly conveyed automatically.

[0036] like Figures 1 to 5 As shown, guide blocks 751 are further installed on both sides of the shearing blade group 75. By setting the guide blocks 751, when shearing the membrane material 101, the two ends of the membrane material 101 can be guided and limited, and the shearing effect is good.

[0037] like Figures 1 to 5 As shown, the controller 61 is connected to the plurality of hydraulic cylinders 72 via electrical wires.

[0038] like Figures 1 to 5 As shown, a guide frame 91 is further installed on the left side of the winding frame 51, and a guide roller 92 is installed on the guide frame 91 to guide the film material 101. The provision of the guide roller 92 is conducive to having a good guiding effect, facilitating the winding of the film material 101 on the winding roller 52, and improving the winding quality.
