Description

Technical Field

[0001] The utility model relates to the technical field of film cutting equipment, in particular to a dust removal device for a film cutting machine. Background Art

[0002] During the membrane cloth processing, a film cutter is needed to adjust the width of the membrane cloth. The film cutter can cut the membrane cloth roll. However, when the cutting blade cuts the membrane material, a large amount of debris is easily generated.

[0003] Through searching, we found the prior art with patent number CN214520737U, and its general scheme is as follows: first, install the membrane cloth roll on the support part, then start the control mechanism to drive the cutter to cut the membrane cloth roll, and there will be flying scraps near the cutting position. At this time, turn on the suction pump, and the suction pump will drive the air in the ventilation pipe to flow into the first box and the second box. The ventilation pipe can collect the flying scraps into the dust collection mechanism, thereby achieving the purpose of improving the cleanliness of the working environment of the film cutting machine. However, the dust hood is installed on the back of the cutting blade. However, when the cutting blade is working, the rotating cutting blade will throw a large amount of cutting scraps onto the frame. Although the dust hood can absorb some scraps, the scraps adsorption effect is not obvious, and there will still be a large amount of cutting scraps on the frame. Utility Model Content

DETAILED DESCRIPTION

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a dust removal device for a film cutting machine, comprising a frame 1, an operating table 6 and a cutting blade 5 arranged on the frame 1, and a dust collector 3 is also provided below the operating table 6; the dust collector 3 comprises a box body 30 for containing liquid, the box body 30 is connected with a second air pipe 33 through a first air pipe 32, and dust hoods 34 are provided at both ends of the second air pipe 33; a sewage outlet 2 is provided on the operating table 6; wherein the sewage outlet 2 is located directly below the cutting blade 5, and the dust hood 34 is installed directly below the sewage outlet 2; a connecting pipe 35 is also provided above the box body 30, and the end of the connecting pipe 35 away from the box body 30 is connected to a negative pressure device.

[0021] To summarize, when the dust hood 34 is installed below the drain outlet 2, the dust hood 34 is used to collect debris generated during film cutting, and the first air pipe 32 and the second air pipe 33 are used to drain the collected debris into the box body 30, and the connecting pipe 35 provided at the upper end of the box body 30 is connected to the negative pressure device to promote the debris to flow quickly into the box body 30, so that the cutting debris can be quickly and reliably sucked into the box body 30 to reduce the amount of debris remaining on the frame 1; at the same time, when the box body 30 contains liquid, such as water, the debris enters the box body 30 and contacts the water, increasing the weight of the debris to reduce the debris entering the connecting pipe 35.

[0022] Based on this, the device can not only improve the debris adsorption capacity but also improve the dust removal effect of the device, especially it can reduce the amount of residual cutting debris on the frame and reduce the problem of debris entering the negative pressure equipment and causing damage to the negative pressure equipment.

[0023] In order to improve the interception capacity of the device and reduce the debris entering the negative pressure device, the box body 30 is further provided with a connection port 39, and the connection port 39 is connected to the filter 38, so that the filter 38 is used to further intercept the debris to reduce the debris flowing upward, especially when the filter 38 is soaked in water, the contact time between the debris and the water can be further increased to increase the weight of the debris. The filter 38 is preferably a cloth bag, and a stainless steel wire mesh can also be used.

[0024] At the same time, since a window 36 is provided on the side of the box body 30 and the window 36 is sealed by a transparent plate, it is convenient for the user to understand the working status of the filter element 38 from the outside, so that the user can replace the filter element 38 in time.

[0025] Since the frame 1 is also provided with an ash baffle 4, and the cutting blade 5 is covered on the frame 1 by the ash baffle 4, the debris can be further prevented from being thrown to the outside of the frame 1. At the same time, the bottom surface of the ash baffle 4 is provided with an inclined surface 7, and the debris is guided to flow to the drain port 2 through the inclined surface 7. Therefore, the inclined surface 7 can be used to reduce the residence time of the debris, so that the debris can automatically flow to the drain port 2.

[0026] On the basis of the above solution, since an air intake branch 31 is further provided at the bottom of the first air pipe 32, and the high-pressure gas is introduced into the interior of the first air pipe 32 through the air intake branch 31, when the high-pressure gas enters the first air pipe 32 through the air intake branch 31, the high-speed flowing gas will form a siphon effect inside the first air pipe 32, so as to further enhance the adsorption capacity of the device, and at the same time, it can reduce the workload of the negative pressure device.

[0027] Furthermore, since a box cover 37 is provided above the box body 30, it is convenient for the user to disassemble and assemble the filter element 38, and it is also convenient to clean the inside of the box body 30; at the same time, since the connecting tube 35 is installed on the box cover 37, the end of the connecting tube 35 away from the negative pressure device can be away from the liquid surface inside the box body 30 to prevent the liquid from being sucked away by the negative pressure device, and at the same time, it can also expand the range of debris movement, thereby reducing the debris from entering the negative pressure device through the connecting tube 35.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
