Description

Technical Field

[0001] The invention belongs to the technical field of grille cutting and rolling, and in particular relates to a plastic grille transverse cutting device with automatic feeding. Background Art

[0002] Plastic grating has excellent water permeability, filtration and durability, and can be widely used in railways, highways, stadiums, dams, hydraulic structures, tunnels, coastal mudflats, reclamation, environmental protection and other projects. In the manufacturing process of plastic grating, the last step is to cut the plastic grating.

[0003] However, the existing plastic grating cutting equipment has the following two problems during use: 1. The existing cutting equipment has insufficient cutting force, and cannot complete the complete cutting of the plastic grating in one go during the cutting process. It needs to be cut twice or even multiple times to cut the geotextile. Not only is the cutting time long and the production efficiency low, but the cut end of the plastic grating is difficult to cut flat and is prone to skewed cutting. 2. After the plastic grating is cut, it is often necessary to manually or mechanically pull out the cut end and rewind it to ensure the winding quality of the geotextile. This not only increases costs but also reduces production efficiency. Those skilled in the art are in urgent need of solving the above technical problems. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides an automatic feeding plastic grating transverse cutting device, which realizes automatic precision cutting and autonomous feeding and winding.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An automatic feeding plastic grille transverse cutting device comprises a frame and a pressing mechanism mounted on the frame, a winding input mechanism is rotatably mounted on one side of the frame close to the pressing mechanism, and a winding roller is rotatably mounted on the other side of the frame, and a cutting mechanism is mounted on the frame directly below the pressing mechanism;

[0007] A cutting cavity is formed at the lower end of the pressing mechanism near the cutting mechanism, and the cutting mechanism is provided with a cutting tool extending into the cutting cavity. The cutting tool is connected to a driving motor, and an output end of the driving motor is connected to the cutting tool to drive the cutting tool to rotate. The driving motor is mounted on a moving component, and the moving component is mounted on a cutting bracket. The moving component drives the cutting tool to move along its axial direction for cutting. The lower end of the cutting bracket is fixed to the frame by a first lifting component, and the first lifting component drives the cutting tool to move up and down to extend into and out of the cutting cavity.

[0008] The clamping mechanism includes an upper pressing plate, a first lower pressing plate, and a second lower pressing plate. The second lower pressing plate is fixedly mounted on the frame. Both ends of the first lower pressing plate are mounted on the frame through a second lifting component and are arranged in parallel with the second lower pressing plate. The first lower pressing plate moves up and down as the second lifting component is extended and retracted. A cutting cavity of the cutting mechanism is formed between the first lower pressing plate and the second lower pressing plate. The upper pressing plate is arranged above the first lower pressing plate and the second lower pressing plate. A support beam is fixedly mounted above the frame. The support beam is connected to the upper pressing plate through a third lifting component. The upper pressing plate moves up and down as the third lifting component is extended and retracted.

[0009] Furthermore, the winding input mechanism includes a driving roller and a driven roller, the driving roller and the driven roller are rotatably mounted on the frame, and the driven roller is connected to a lifting device.

[0010] Furthermore, the cutting tools and driving motors are provided in number three and are evenly installed on the moving component.

[0011] Furthermore, the moving parts include linear rails, sliders, and moving cylinders. The linear rails are installed on the cutting bracket. The sliders are provided in three groups and are slidably installed on the linear rails for the installation of three drive motors.

[0013] Furthermore, the first lifting component, the second lifting component, and the third lifting component are configured as lifting cylinders.

[0014] Beneficial effects: The present invention provides an automatic feeding plastic grille transverse cutting device. The plastic grille is input through a winding input mechanism and is put on a winding roller through a pressing mechanism. The cutting tool is moved upward along the first lifting component to the cutting chamber. The driving motor drives the cutting tool to rotate while the cutting tool moves back and forth along the moving component to complete the cutting action, achieving automatic and precise cutting. The device is equipped with three sets of cutting tools to further improve the cutting speed.

[0015] After cutting is completed, the cutting tool moves out of the cutting chamber, and the upper pressure plate and the first lower pressure plate drive the plastic grid to move upward, higher than the surface of the second lower pressure plate. At the same time, the winding input mechanism feeds the material. Under the action of forward thrust and gravity, the plastic grid passes through the cutting chamber and moves forward to the winding roller through the second lower pressure plate, realizing automatic feeding and winding operations, with a high degree of automation, while improving product quality and production speed.

DETAILED DESCRIPTION

[0024] The following will provide a clear and complete description of 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] like Figure 1 、 2 As shown, the present invention provides an automatic feeding plastic grid transverse cutting device, comprising a frame 1 and a pressing mechanism 4 mounted on the frame 1, a winding input mechanism 3 is rotatably mounted on one side of the frame 1 close to the pressing mechanism 4, and a winding roller 6 is rotatably mounted on the other side. A cutting mechanism 5 is mounted on the frame 1 directly below the pressing mechanism 4;

[0026] like Figure 3As shown, a cutting chamber is formed at the lower end of the pressing mechanism 4 near the cutting mechanism 5. The cutting mechanism 5 is provided with a cutting tool 51 extending into the cutting chamber. The cutting tool 51 is connected to a driving motor 55. The output end of the driving motor 55 is connected to the cutting tool 51 and drives the cutting tool 51 to rotate. The driving motor 55 is mounted on a moving component 52, and the moving component 52 is mounted on a cutting bracket 53. The moving component 52 drives the cutting tool 51 to move along its axial direction for cutting. The lower end of the cutting bracket 53 is fixed to the frame 1 by a first lifting component 54. The first lifting component 54 drives the cutting tool 51 to move up and down and extend into and out of the cutting chamber.

[0027] like Figure 4 、 5 As shown, the clamping mechanism 4 includes an upper pressing plate 41, a first lower pressing plate 42, and a second lower pressing plate 43. The second lower pressing plate 43 is fixedly mounted on the frame 1. Both ends of the first lower pressing plate 42 are mounted on the frame 1 through a second lifting component 44 and are arranged in parallel with the second lower pressing plate 43. The first lower pressing plate 42 moves up and down as the second lifting component 44 is extended and retracted. A cutting chamber of the cutting mechanism 5 is formed between the first lower pressing plate 42 and the second lower pressing plate 43. The upper pressing plate 41 is arranged above the first lower pressing plate 42 and the second lower pressing plate 43. A support beam 11 is fixedly mounted above the frame 1. The support beam 11 is connected to the upper pressing plate 41 through a third lifting component 45. The upper pressing plate 41 moves up and down as the third lifting component 45 is extended and retracted.

[0028] During operation, the plastic grille is fed through the winding input mechanism 3 and is then fed to the winding roller 6 through the pressing mechanism 4. When the winding roller 6 completes winding, the winding input mechanism 3 stops feeding the plastic grille. At the same time, the upper pressing plate 41 of the pressing mechanism 4 moves downward along with the third lifting component 45, completely clamping the plastic grille on the first lower pressing plate 42 and the second lower pressing plate 43. The cutting mechanism 5 is then started, and the cutting tool 51 rises and moves into the cutting chamber along with the first lifting component 54. The driving motor 55 drives the cutting tool 51 to rotate while the cutting tool 51 moves back and forth along the moving component 52, completing the cutting operation of the plastic grille.

[0029] After the cutting is completed, the cutting tool 51 stops rotating and moves out of the cutting chamber with the first lifting component 54. At this time, the upper pressure plate 41 and the first lower pressure plate 42 drive the plastic grid to move up synchronously with the second lifting component 44 and the third lifting component 45 respectively. When the upper surface of the first lower pressure plate 42 slowly becomes higher than the upper surface of the second lower pressure plate 43, and the winding input mechanism 3 continues to feed, the plastic grid passes through the cutting chamber under the action of forward thrust and gravity, and moves forward to the winding roller 6 through the second lower pressure plate 43. After that, the upper pressure plate 41 and the first lower pressure plate 42 move downward synchronously until the upper surface of the first lower pressure plate 42 is flush with the upper surface of the second lower pressure plate 43, and the winding operation continues.

[0030] On the basis of the above embodiment, in order to adapt to the winding of plastic grids with different thickness specifications, such as Figure 6 As shown, the winding input mechanism 3 includes an active roller 31 and a driven roller 32. The active roller 31 and the driven roller 32 are rotatably mounted on the frame 1. The driven roller 32 is connected to a lifting device 33. The lifting device 33 is telescopic to adjust the distance between the active roller 31 and the driven roller 32.

[0031] On the basis of the above embodiment, in order to further speed up the cutting speed of the plastic grid, three cutting knives 51 and three driving motors 55 are respectively provided and evenly installed on the moving component 52 .

[0032] Based on the above embodiments, Figure 7 As shown, the moving component 52 includes a linear rail 521, a slider 522, and a moving cylinder 523. The linear rail 521 is installed on the cutting bracket 53. The slider 522 is provided in three groups and is slidably installed on the linear rail 521 for the installation of three drive motors 55. The three groups of sliders 522 are fixedly connected by a connecting plate, and the lower end of one group of sliders 522 is connected to the moving cylinder 523. The moving cylinder 523 is telescopic to drive the three groups of sliders 522 to move left and right along the linear rail 521, so that the three cutting tools 51 can perform cutting operations synchronously, thereby speeding up the cutting speed.

[0033] On the basis of the above embodiment, in order to further improve the tension of the plastic grille, a tensioning roller 2 is provided on the frame 1 below the winding input mechanism 3, and two tensioning rollers 2 are arranged longitudinally in parallel. The two tensioning rollers 2 are rotatably mounted on the frame 1, and the plastic grille enters upward from the tensioning roller 2 below. After being tensioned by the two tensioning rollers 2, it is reversed and output by the winding input mechanism 3.

[0034] On the basis of the above embodiment, the first lifting component 54 , the second lifting component 44 , and the third lifting component 45 are configured as lifting cylinders.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. The front, back, left and right used in the text are not specific, and are mainly for a more intuitive description of the technical solution, and do not have a limiting effect. Those skilled in the art should understand that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the scope of protection of the present invention.
