Description

Technical Field

[0001] This utility model relates to the field of flexible fabric cutting machine technology, and in particular to a machine tool device and machine tool equipment for a flexible fabric cutting machine. Background Technology

[0002] In the field of flexible fabric cutting technology, cutting machines are commonly used to cut flexible fabrics. A cutting machine is equipped with a conveying device and a cutting device. The conveying device transports the flexible fabric forward, while the cutting device cuts the flexible fabric laid on the machine tool. The conveying device may employ roller-type or track-type conveyors. The cutting device uses a cutter and a drive mechanism to move the cutter.

[0003] To hold the flexible fabric in place, negative pressure adsorption is generally used to hold the flexible fabric above.

[0004] In the prior art, such as Chinese invention patent publication number CN111893739A, a textile fabric cutting device using the negative pressure principle is disclosed. An air duct is provided at the top of the base, and multiple fans are installed on the side of the air duct. A worktable is located above the air duct. When the fans are turned on, suction is generated within the air duct, making the air pressure inside the air duct lower than the outside air pressure. The suction gap of the worktable then generates suction, completely eliminating the cavity between the fabric and the worktable, allowing the fabric to fit snugly against the worktable and preventing wrinkles caused by the presence of cavities.

[0005] In the aforementioned prior art, the fan is installed on the side of the base and exposed on one side of the machine tool, which has the following drawbacks: 1. The noise generated after the fan is turned on is all transmitted into the workshop, which is very loud.

[0006] 2. The fan is exposed on the side of the machine body, making it susceptible to damage from impacts and entanglement hazards. For example, tools held by workers may come into contact with the fan, causing damage. Also, leftover fabric scraps temporarily piled up beside the machine may get caught in the fan and become entangled with the blades.

[0007] 3. The air blown out by the fan blows directly towards the side of the workbench, causing airflow turbulence above the workbench and adversely affecting the adsorption of the flexible fabric. Utility Model Content

Detailed Implementation

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] like Figure 1-5 As shown, an embodiment of the present invention provides a machine tool device for a flexible fabric cutting machine. The machine tool device includes a machine tool body 1 having a negative pressure groove 13 and a mounting groove 14, an exhaust assembly 2 disposed in the mounting groove 14, an exhaust pipe assembly 3 connecting the negative pressure groove 13 and the exhaust assembly 2, and an exhaust pipe assembly 5 connected to the exhaust assembly 2.

[0026] The negative pressure groove 13 and the mounting groove 14 are spaced apart. The mounting groove 14 is located in front of the negative pressure groove 13. A cover plate 15 is detachably installed on the top opening of the mounting groove 14.

[0027] The machine tool device provided by this utility model is part of a flexible fabric cutting machine. Flexible fabrics include not only cloth but also non-woven flexible materials and functional flexible composite materials with soft texture and bendable deformation properties. The flexible fabric cutting machine is used to cut flexible fabrics to the required size.

[0028] The machine tool device provided by this utility model is mainly used to provide negative pressure so that the worktable can adsorb the flexible fabric above.

[0029] The machine tool device provided by this utility model includes a machine tool body 1, an exhaust assembly 2, an exhaust pipe assembly 3, and an exhaust pipe assembly 4.

[0030] The main body 1 of the machine tool can be divided into a front half 11 and a rear half 12. Of course, the distinction between the front half 11 and the rear half 12 is only for the convenience of description and does not necessarily represent the forward and backward direction of the machine during use.

[0031] The machine tool body 1 is provided with mounting grooves 14 and negative pressure grooves 13 spaced apart from each other. The negative pressure groove 13 is located in the rear half 12 of the machine tool body 1, and the mounting groove 14 is located in the front half 11 of the machine tool body 1.

[0032] The top opening of the negative pressure groove 13 serves as a worktable for adsorbing flexible fabrics. The worktable can be formed by arranging rollers, supporting ribs, etc., or other methods can be used.

[0033] The mounting groove 14 can be the entire groove in the front half 11 of the machine tool body 1, or a box structure can be specially set in the entire groove in the front half. The part of the box structure other than the cover plate 15 can also be called the mounting groove 14.

[0034] The exhaust assembly 2 can be a fan or similar device, installed in the mounting groove 14 and then sealed by the cover plate 15. This reduces the outward transmission of noise and prevents damage from external objects, thus improving production safety. The air inlet and exhaust outlet of the exhaust assembly 2 can extend outside the mounting groove 14 or be installed inside the mounting groove 14.

[0035] In this invention, the exhaust component 2 can be a conventional fan or ventilator, and multiple fans or ventilators can be arranged as needed.

[0036] The exhaust pipe assembly 3 is connected between the negative pressure groove 13 and the air inlet of the exhaust assembly 2, and is used to extract air from the negative pressure groove 13 to create a negative pressure in the negative pressure groove 13. It should be noted that the negative pressure groove 13 is a groove located in the rear half 12 of the machine tool body 1. When the exhaust assembly 2 is not working, its internal air pressure is basically the same as the external air pressure. When the exhaust assembly 2 is working, its internal air pressure is lower than the external air pressure, which helps to attract the flexible fabric on the worktable.

[0037] The exhaust piping assembly 3 includes some connectors, exhaust pipes, etc., used to transport gas in the negative pressure tank 13 to the exhaust assembly 2.

[0038] The exhaust pipe assembly 5 is connected to the air outlet of the exhaust assembly 2. The exhaust pipe assembly 5 includes some connectors, exhaust pipes 51, etc., and is used to exhaust the air output by the exhaust assembly 2 to a designated area.

[0039] When the exhaust system 2 is turned on, the gas in the negative pressure tank 13 can be drawn into the exhaust pipe assembly 3, then into the exhaust system 2, and then discharged through the exhaust pipe assembly 3, thereby creating a negative pressure in the negative pressure tank 13, which helps the workbench above to adhere to the flexible fabric, which is beneficial for cutting the flexible fabric.

[0040] In this invention, the exhaust assembly 2 is located inside the machine tool body 1 and is sealed in the mounting groove 14 by the cover plate 15, which can greatly reduce noise, avoid danger, and improve production safety.

[0041] In one embodiment, such as Figure 9 As shown, the exhaust assembly 2 includes a pressurized exhaust fan 21. The air inlet of the pressurized exhaust fan 21 is connected to the exhaust assembly 2, and the exhaust outlet of the pressurized exhaust fan 21 is connected to the exhaust pipe assembly 5.

[0042] In this utility model, the exhaust assembly 2 adopts a pressure exhaust fan 21, which can also be called a negative pressure fan. The power of the pressure exhaust fan 21 is generally above 20KW. It has a large suction force and forms a large negative pressure in the negative pressure groove 13, which is more conducive to helping the workbench above to adsorb the flexible fabric.

[0043] The pressurized exhaust fan 21 can be a centrifugal pressurized fan, an axial flow pressurized fan, or a pressurized fan with a turbine, etc.

[0044] In one embodiment, such as Figure 6 and Figure 8-9 As shown, the exhaust assembly 2 includes a fan mounting box 22, a pressurized exhaust fan 21 is installed inside the fan mounting box 22, the fan mounting box 22 is fixedly installed in the mounting groove 14, and a ventilation window 223 is provided on one side wall of the fan mounting box 22.

[0045] In this embodiment, the pressurized exhaust fan 21 is installed in the fan mounting box 22, which serves both a protective function and a noise reduction function.

[0046] In this embodiment, the pressurized exhaust fan 21 is installed in the fan mounting box 22, which is installed in the mounting slot 14, and then the cover plate 15 is closed, which serves as a double noise reduction function. The fan mounting box 22 performs the first noise reduction on the noise generated by the pressurized exhaust fan 21, and the mounting slot 14 and cover plate 15 perform the second noise reduction on the noise generated by the pressurized exhaust fan 21, further improving the noise reduction effect.

[0047] The fan mounting box 22 has a ventilation window 223 on one side wall for heat dissipation of the pressurized exhaust fan 21.

[0048] Specifically, the fan mounting box 22 includes a mounting box base 221 and a mounting box cover 222 detachably connected to the mounting box base 221. A ventilation window 223 is provided on one side wall of the mounting box cover 222.

[0049] During assembly, the mounting box base 221 is fixed to the bottom plate of the mounting slot 14, the pressurized exhaust fan 21 is fixedly installed on the mounting box base 221, and then the mounting box cover 222 is fastened to cover the pressurized exhaust fan 21. The mounting box cover 222 can be connected to the mounting box base 221 by buckles, pins, etc.

[0050] The air inlet and exhaust outlet of the pressurized exhaust fan 21 can extend outside the fan mounting box 22 for connection to pipelines.

[0051] In one embodiment, such as Figure 1-3 and Figure 11 As shown, the exhaust tail end 52 of the exhaust pipe assembly 5 is located on the side or front of the mounting groove 14.

[0052] And / or, the exhaust tail end 52 is provided with a sound-absorbing and noise-reducing layer 53.

[0053] In this embodiment, the tail end of the exhaust pipe 51 is referred to as the exhaust tail end 52, which is used to discharge gas to the surrounding area of ​​the machine tool body 1. The exhaust tail end 52 is located on the side or front of the mounting groove 14. The exhaust tail end 52 can be horizontally or vertically located on the side or front of the mounting groove 14, at a certain distance from the negative pressure groove 13. Therefore, the gas discharged from the exhaust tail end 52 can reduce interference with the airflow above the negative pressure groove 13 and reduce interference with the flexible fabric laid on the worktable.

[0054] In this embodiment, one or more sound-absorbing and noise-reducing layers 53 may be applied to the exhaust tail end 52 to further enhance the noise reduction effect. The sound-absorbing and noise-reducing layer 53 may be made of sound-absorbing cotton or the like.

[0055] In one embodiment, such as Figure 1-3 As shown, the exhaust tail end 52 is located on the oblique front side of the mounting groove 14 and extends vertically upward.

[0056] In this embodiment, the exhaust tail end 52 is located on the oblique front side of the mounting groove 14, for example, at one corner of the front end of the machine tool body 1, and extends vertically. This arrangement allows the exhaust tail end 52 to be farther away from the negative pressure groove 13, and the gas discharged upward completely leaves the top of the negative pressure groove 13, minimizing interference with the airflow above the negative pressure groove 13 and minimizing interference with the flexible fabric laid on the worktable.

[0057] In one embodiment, such as Figure 1-3 and Figure 6 As shown, the exhaust end of the ventilation assembly 2 is connected to the muffler assembly 4, and the intake end of the exhaust pipe assembly 5 is connected to the exhaust end of the muffler assembly 4.

[0058] In this embodiment, a noise reduction component 4 is connected between the ventilation component 2 and the exhaust pipe component 5, which further improves the noise reduction effect.

[0059] The noise reduction component 4 can be installed on the outside of the mounting groove 14 or inside the mounting groove 14.

[0060] The silencing component 4 is a device that can silence the passing gas, such as a silencer or a silencer pipe.

[0061] In one embodiment, such as Figure 10 As shown, the muffler assembly 4 includes a muffler 41, the air inlet of which is connected to the air outlet of the exhaust assembly 2, and the exhaust outlet of the muffler 41 is connected to the exhaust pipe assembly 5.

[0062] In this embodiment, the noise reduction component 4 includes a silencer 41, which has multiple silencer pipes, multiple silencer baffles or multiple silencer flow lines inside, and has a good noise reduction effect.

[0063] In one embodiment, such as Figure 6 As shown, the muffler assembly 4 includes a muffler mounting box 42, the muffler 41 is installed inside the muffler mounting box 42, and the muffler mounting box 42 is fixedly installed inside the mounting slot 14.

[0064] In this embodiment, a muffler mounting box 42 is also provided specifically for the muffler 41. The muffler 41 is installed in the muffler mounting box 42, which serves both a protective function and a noise reduction function.

[0065] The muffler mounting box 42 performs primary noise reduction on the noise generated by the muffler 41. The muffler mounting box 42 is fixedly installed in the mounting slot 14 and covered with the cover plate 15 to achieve secondary noise reduction.

[0066] In one embodiment, such as Figure 1-7 As shown, the negative pressure groove 13 and the mounting groove 14 are separated by a partition 16, and an air extraction port 17 is provided on the partition 16.

[0067] The air extraction pipeline assembly 3 includes a docking box 31 and a filter module 32.

[0073] The air extraction pipeline assembly 3 includes a docking box 31, a filter module 32, and a connecting pipe 33, etc.

[0074] The docking box 31 is located in the mounting groove 14 and is connected to the air extraction port 17 to achieve air passage communication with the negative pressure groove 13.

[0075] The filter module 32 is located on the front side of the docking box 31, and has a filter element (not shown in the figure) inside it for filtering the air flowing through it.

[0076] The exhaust component 2 is installed on one side of the docking box 31, and the two are roughly next to each other, reducing the space occupied by the layout.

[0077] The air inlet of the filter module 32 is connected to the front side plate of the docking box 31 and communicates with the cavity of the docking box 31, thereby connecting the air inlet and exhaust port 17 of the filter module 32. The air outlet of the filter module 32 is connected to the air inlet of the exhaust assembly 2 through the connecting pipe 33.

[0078] After the exhaust assembly 2 is turned on, the air in the negative pressure tank 13 is drawn into the docking box 31 through the air extraction port 17, and enters the exhaust assembly 2 after being filtered by the filter module 32, which can reduce the impact of impurities in the air on the exhaust assembly 2.

[0079] In one embodiment, such as Figure 6 and Figure 13 As shown, the filter module 32 includes an outer tube 321 and an inner tube 322. The outer tube 321 is fitted onto the inner tube 322, and an annular gap is formed between the two.

[0081] The gas in the docking box 31 can flow through the annular gap to the front end of the outer pipe 321, then flow into the inner pipe 322, and then flow through the connecting pipe 33 to the exhaust assembly 2.

[0082] The filter element can be installed in the inner tube 322, which increases the length of the filter element that can be installed and helps to improve the filtration effect.

[0089] Specifically, the tracked conveyor 6 includes an annular conveyor track 61, with its front and rear ends tensioned by a drive shaft and a driven shaft, respectively, and a drive motor connected to the drive shaft. The drive motor can be located inside the negative pressure groove 13 or outside the negative pressure groove 13.

[0090] The conveyor belt 61 is equipped with multiple track plates 62, which are rectangular but can also be other shapes. Therefore, a gap is formed between any two adjacent track plates 62, which is used for air suction and is called the suction gap 63.

[0091] The multiple track plates 62 on the top surface of the tracked conveyor 6 are located in the top opening of the negative pressure groove 13 and are in a plane, roughly flush with the top surface of the top opening, thus it can be used as an adsorption worktable.
