[0013] Beneficial effects

[0014] This invention provides a device for collecting tailings from the inclined surface of a laser cutting machine. Compared with the prior art, it has the following advantages:

[0015] (1) The inclined tail material collection device of the laser cutting machine, when the cut cloth passes through the inclined surface of the metal mesh conveyor belt, the cloth strip is conveyed to the left by the conveyor belt. Since the inclined surface of the metal mesh conveyor belt still has an adsorption force at this time, the tail material is forced to be adsorbed on the inclined surface of the metal mesh conveyor belt and move obliquely downward, so that the tail material is separated from the cloth strip and the tail material is effectively collected, avoiding the problem that the tail material is difficult to collect due to melting and sticking to the adjacent cloth strip.

[0016] (2) When the tail material of the laser cutting machine is conveyed obliquely downward by the oblique surface of the metal mesh conveyor belt to the perforated conveyor belt area, the tail material has left the suction range of the first exhaust hood and entered the suction range generated by the second exhaust hood. The suction generated by the second exhaust hood will adsorb the tail material on the perforated conveyor belt, thus avoiding the tail material from adhering to the metal mesh conveyor belt. When the tail material is conveyed to the tail material collection box position on the perforated conveyor belt, the tail material has left the suction range of the second exhaust hood. Under the action of gravity, the tail material falls into the tail material collection box, ensuring the continuity and integrity of the tail material collection process. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution:

[0025] Figures 1-5 An embodiment is shown: A beveled tail material collection device for a laser cutting machine includes a frame 1. A feeding assembly 2 is located inside the frame 1. A beveled tail material collection assembly 3 and an anti-sagging assembly 5 are located to the left of the feeding assembly 2 inside the frame 1. The anti-sagging assembly 5 is positioned above the beveled tail material collection assembly 3. An air extraction assembly 4 is located between the feeding assembly 2 and the beveled tail material collection assembly 3. The feeding assembly 2 includes a first drive roller 21 and a first inclined pull roller 22 rotatably mounted on the inner wall of the frame 1. Two first drive rollers 21 are mounted on the same horizontal plane. The first inclined pull roller 22 is positioned to the left and below the first drive rollers 21. The position of the first drive roller 21 and the first inclined pull roller 22 is provided with a metal mesh drive belt 23; the inclined tail material collection assembly 3 includes a second drive roller 31 and a second inclined pull roller 32 rotatably set on the inner wall of the frame 1. The number of second drive rollers 31 is set to two and they are on the same horizontal plane. The second drive roller 31 on the right is located directly above the first inclined pull roller 22 and is slightly higher than the first inclined pull roller 22. The second inclined pull roller 32 is located to the right of the first drive roller 21 and above it. The second inclined pull roller 32 is lower than the first drive roller 21. A perforated conveyor belt 33 is provided between the two second drive rollers 31 and the second inclined pull roller 32.

[0026] The metal mesh transmission belt 23 forms an inclined structure through the first inclined pull roller 22 and the first transmission roller 21 on the left. The perforated transmission belt 33 forms an inclined structure through the second inclined pull roller 32 and the second transmission roller 31 on the right. The inclined structure on the perforated transmission belt 33 is slightly higher than the inclined structure on the metal mesh transmission belt 23 and they are parallel to each other.

[0027] The exhaust assembly 4 includes a first exhaust hood 41 and a second exhaust hood 42 installed on the inner wall of the frame 1. The first exhaust hood 41 has an upward opening, and the second exhaust hood 42 has a downward opening. The first exhaust hood 41 is placed inside the metal mesh conveyor belt 23, and the opening of the first exhaust hood 41 is adapted to the horizontal inner top surface and the inclined inner top surface of the metal mesh conveyor belt 23. The second exhaust hood 42 is placed inside the perforated conveyor belt 33, and the opening of the second exhaust hood 42 is adapted to the horizontal inner bottom surface and the inclined inner bottom surface of the perforated conveyor belt 33. The openings of the first exhaust hood 41 and the second exhaust hood 42 are connected but do not intersect. Both the surfaces of the first exhaust hood 41 and the second exhaust hood 42 are connected by connecting pipes 43. The connecting pipes 43 penetrate the inner wall of the frame 1 and extend outward. The two connecting pipes 43 are connected by an exhaust pipe 44.

[0028] Specifically, the exhaust pipe 44 is connected to an external negative pressure fan, causing the first exhaust hood 41 and the second exhaust hood 42 to generate suction. The fabric is then placed on the metal mesh conveyor belt 23, and the suction generated by the first exhaust hood 41 causes the fabric to be adsorbed onto the metal mesh conveyor belt 23. After that, the motor 24 starts, and works in conjunction with the first transmission roller 21 and the first inclined pull roller 22 to make the metal mesh conveyor belt 23 start to run. The fabric is then transported to the cutting position of the laser cutting machine 9 for cutting. When the cut fabric passes over the inclined surface of the metal mesh conveyor belt 23, the fabric strips are transported to the left by the conveyor belt 52. Since the inclined surface of the metal mesh conveyor belt 23 still has an adsorption force, the tail material is forced to be adsorbed on the inclined surface of the metal mesh conveyor belt 23 and move diagonally downwards, separating the tail material from the fabric strips. This ensures the effective collection of the tail material and avoids the problem of the tail material being difficult to collect due to melting and sticking to adjacent fabric strips.

[0029] In this embodiment, the anti-sagging component 5 includes two third transmission rollers 51 rotatably mounted on the inner wall of the frame 1, a conveyor belt 52 is provided between the two third transmission rollers 51, and the top surface of the conveyor belt 52 is at the same height as the horizontal plane of the metal mesh transmission belt 23.

[0030] Specifically, the conveyor belt 52 can provide support for the fabric on the metal mesh transmission belt 23, preventing the fabric from sagging due to its own weight or other factors, and ensuring the flatness and conveying stability of the fabric.

[0031] In this embodiment, the fabric feeding assembly 2 also includes a motor 24 installed on the outer wall of the frame 1, and the output shaft end of the motor 24 is fixedly connected to the end of the first transmission roller 21 on the right side.

[0032] Specifically, the metal mesh transmission belt 23 can start running when the motor 24 is started, in conjunction with the operation of the first transmission roller 21 and the first inclined pull roller 22.

[0033] In this embodiment, a synchronous pulley set 6 is provided between the ends of the left first transmission roller 21 and the right third transmission roller 51, and a gear set 7 is provided between the ends of the right second transmission roller 31 and the first inclined pull roller 22.

[0034] Specifically, the synchronous pulley set 6 consists of two synchronous pulleys and a synchronous belt, which is used to transmit the power of the first transmission roller 21 on the left to the third transmission roller 51 on the right, thereby driving the conveyor belt 52 to rotate. The gear set 7 consists of two meshing gears, which is used to transmit the power of the first inclined pull roller 22 to the second transmission roller 31 on the right, thereby driving the perforated conveyor belt 33 to rotate.

[0035] A tail material collection box 8 is provided on the bottom surface of the frame 1 near the left side, and the tail material collection box 8 is placed below the perforated conveyor belt 33. A laser cutting machine 9 is installed on the upper part of the frame 1 near the right side, and the laser cutting machine 9 is fixedly connected to the outer surface of the frame 1 through a bracket.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, the exhaust pipe 44 is connected to an external negative pressure fan, which generates suction in the first exhaust hood 41 and the second exhaust hood 42. The fabric is then placed on the metal mesh transmission belt 23, and the suction generated by the first exhaust hood 41 causes the fabric to be adsorbed onto the metal mesh transmission belt 23. After that, the motor 24 starts and works in conjunction with the first transmission roller 21 and the first inclined pull roller 22 to make the metal mesh transmission belt 23 start to run. During the operation of the first transmission roller 21, the conveyor belt 52 runs through the coordinated action of the synchronous pulley group 6. During the operation of the first inclined pull roller 22, the perforated conveyor belt 33 runs through the coordinated action of the gear group 7.

[0038] The fabric is fed to the cutting position of the laser cutting machine 9 for cutting. The strips of fabric that need to be retained are placed on the conveyor belt 52, and the fabric is pulled by an external traction device for winding. The conveyor belt 52 can prevent the fabric conveyed on the metal mesh transmission belt 23 from sagging, ensuring that the fabric remains flat during the conveying process.

[0039] When the cut fabric passes over the inclined surface of the metal mesh conveyor belt 23, the fabric strips are conveyed to the left by the conveyor belt 52. Since the inclined surface of the metal mesh conveyor belt 23 still has an adsorption force, the tail material is forced to be adsorbed on the inclined surface of the metal mesh conveyor belt 23 and move downwards at an angle, so that the tail material is separated from the fabric strips, ensuring the effective collection of the tail material and avoiding the problem that the tail material is difficult to collect due to melting and sticking to adjacent fabric strips.

[0040] When the tail material is conveyed obliquely downwards by the inclined surface of the metal mesh conveyor belt 23 to the area of ​​the perforated conveyor belt 33, it has already left the suction range of the first exhaust hood 41 and entered the suction range of the second exhaust hood 42. The suction generated by the second exhaust hood 42 adsorbs the tail material onto the perforated conveyor belt 33, thus preventing the tail material from adhering to the metal mesh conveyor belt 23. When the tail material is conveyed to the tail material collection box 8 by the perforated conveyor belt 33, it has already left the suction range of the second exhaust hood 42 and falls into the tail material collection box 8 under the action of gravity.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
