Description

Technical Field

[0001] The invention relates to laser cutting technology, in particular to laser cutting equipment for producing mountaineering backpacks. Background Art

[0002] Laser cutting machines use laser beams to cut workpieces. Current laser cutting machines can also cut fabrics, achieving fast and precise cutting and achieving the goal of precise cutting. Its main principle is to use the energy of the laser to concentrate it into a high-density beam in the form of light. The beam is transmitted to the work surface, generating enough energy to melt the material to achieve the purpose of cutting and engraving. Laser cutting machines have the characteristics of high precision, fast cutting speed, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. In recent years, they have been widely used.

[0003] The laser cutting head is an important component of the laser cutting machine. Currently, the laser cutting heads on the market are mainly concentrated in medium and low power. The greater the power of the laser cutting head, the thicker the metal sheet that can be cut. Therefore, the market demand for high-power laser cutting heads is increasing. However, the higher the power of the laser cutting head, the higher the frequency of installation and replacement. The current laser cutting head is mainly fixed with bolts, which is not convenient for timely replacement. Moreover, after replacement, it is necessary to debug whether the laser is in the center position, which makes it difficult to quickly replace and debug the laser head, affecting normal operation efficiency.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0040] like Figures 1 to 17 As shown, the laser cutting equipment for producing mountaineering backpacks of the present invention includes a shell 1 and a laser cutting mechanism 2. A hinged cover 3 is provided on the shell 1, and the cover 3 is opened by a hinged manner to facilitate internal inspection. A fixed frame 4 is provided inside the shell 1, and an up and down moving component 5, a left and right moving component 6, and a front and back moving component 7 are provided on the fixed frame 4. A supporting plate 8 is provided in the up and down moving component 5, and fabric can be placed on the supporting plate 8. A strip groove 9 is provided on the shell 1, and the strip groove 9 is provided on the front and rear parts of the shell 1 to facilitate fabric feeding and realize rapid laser cutting of a roll of fabric. The up and down moving component 5 can drive the supporting plate 8 to move up and down, thereby changing the distance between the fabric and the laser cutting mechanism 2.

[0041] A first moving motor 10 is provided in the up-and-down moving assembly 5. A second belt 11 is provided on the first moving motor 10. The first moving motor 10 drives the second belt 11 to rotate. Positioning rods 12 and screw rods 13 are provided around the carrier plate 8. Gears are provided on the screw rod 13. Through the engagement of corresponding gears provided on the second belt 11, the second belt 11 drives the screw rod 13 to rotate, thereby lifting the carrier plate 8 and driving the carrier plate 8 toward or away from the laser cutting mechanism 2. The corresponding transmission structures will not be elaborated on here, as they are already existing transmission methods.

[0042] The forward and backward moving component 7 also relies on the cooperation of the motor and the belt to enable the left and right moving component 6 to move on the forward and backward moving component 7. A first slide rail 14 is provided on the left and right moving component 6, and a slide seat 15 is provided on the first slide rail 14, so that the laser cutting mechanism 2 can be installed on the slide seat 15, and the slide seat 15 is driven to move by the first belt 16 to realize the left and right movement of the laser cutting mechanism 2.

[0043] The laser cutting mechanism 2 is arranged on the left-right moving assembly 6, which is provided with a first slide rail 14 and a first belt 16. The laser cutting mechanism 2 is provided with a slide 15 installed on the first slide rail 14, a holding assembly 17 cooperating with the first belt 16, a laser head 18, and a limit assembly 19 for limiting the position of the laser head 18. The slide 15 is arranged on the first slide rail 14, and the holding assembly 17 is arranged on the slide 15 and connected to the first belt 16, thereby ensuring that the first belt 16 can drive the slide 15 to move on the first slide rail 14. The limit assembly 19 is used for the installation of the laser head 18, and the limit assembly 19 is connected to the slide 15. The holding assembly 17 is arranged on the slide 15, and the limit assembly 19 is cooperating with one side of the slide 15. The laser head 18 is connected to the slide 15 through the limit assembly 19.

[0044] Example 1

[0045] The retaining assembly 17 includes a retaining seat 20 and a retaining member 21. The retaining member 21 is hingedly connected to the retaining seat 20. The retaining seat 20 is provided with an arcuate portion 22, with an arcuate opening 23 formed in the middle of the arcuate portion 22. The retaining member 21 is provided with an arcuate slot 24 that cooperates with the arcuate portion 22, and a hinge portion 25 that cooperates with the arcuate opening 23. The arcuate opening 23 cooperates with the hinge portion 25 to achieve the hinged connection of the retaining member 21 to the retaining seat 20. The retaining member 21 can rotate about the centerline of the hinge portion 25, while the arcuate slot 24 limits the rotation angle of the arcuate portion 22. The retaining member 21 is provided with a prying plate 26, which allows the retaining member 21 to rotate about the hinge portion 25.

[0046] An adjusting member 27 is provided at the lower end of the retaining seat 20 , and the adjusting member 27 is arranged on the slide 15 . A retaining groove 28 cooperating with the first belt 16 is provided on the retaining seat 20 and the retaining member 21 . A symmetrically arranged positioning column 29 is provided in the retaining groove 28 on the retaining seat 20 .

[0047] Retaining blocks 30 are provided on both sides of the retaining seat 20, and fixed blocks 31 are provided on the slide 15 to cooperate with the retaining blocks 30. The fixed blocks 31 are provided with transverse grooves 32 and vertical grooves 33 that cooperate with the retaining blocks 30. The transverse grooves 32 are located in the middle of the vertical grooves 33. Here, the transverse grooves 32 are not located in the middle of the vertical grooves 33, but are located in the middle of the two ends. When the retaining block 30 is installed from the transverse groove 32, it then enters the vertical groove 33 and is at the lower end of the transverse groove 32. The second belt 11 is then placed in the retaining groove 28, so that the positioning column 29 in the retaining groove 28 cooperates with the positioning hole (not shown in the figure) on the second belt 11 for positioning. The adjusting member 27 can then be rotated so that the adjusting member 27 pushes the retaining seat 20 to move upward, so that the fixing block 31 reaches the upper end of the transverse groove 32. At this time, as the retaining seat 20 rises, the second belt 11 is pulled by force, keeping the middle of the second belt 11 moving upward, tightening the second belt 11 to facilitate the drive of the motor, and also to achieve a close connection between the second belt 11 and the retaining assembly 17.

[0048] The retaining member 21 is provided with a retaining end 34, and the retaining seat 20 is provided with an extension 35. The extension 35 is provided with a stopper 36. The stopper 36 is rotated to adjust the distance between the retaining end 34 and the extension 35. Rotating the stopper 36 allows the upper end of the stopper 36 to contact the retaining end 34. When the retaining member 21 is rotated, the stopper 36 restricts the rotation of the retaining member 21, preventing the retaining member 21 from becoming loose with the retaining seat 20 and affecting the position of the second belt 11.

[0049] Since the retaining assembly 17 and the second belt 11 do not need to be frequently replaced, the limiting bolt 36 and the adjusting member 27 can be rotated to prevent the retaining member 21 from rotating, and the second belt 11 is tightened.

[0050] Example 2

[0051] The laser head 18 needs to be replaced and maintained, so it needs to be easy to quickly disassemble and assemble as well as to debug the laser after installation.

[0052] The limiting assembly 19 includes a limiting seat 37, a limiting member 38, and a pushing member 39. A movable area 40 is formed in the middle of the limiting seat 37. The limiting member 38 and pushing member 39 are disposed within the movable area 40. A closed opening 41 is provided at one end of the movable area 40, and a connecting hole 42 is provided at the other end. A T-shaped slot 43 is provided on the limiting seat 37 at one end near the connecting hole 42, and a T-shaped block 44 is provided on the laser head 18 to cooperate with the T-shaped slot 43. A push rod 45 is provided at the upper end of the pushing member 39. The limiting seat 37 is provided with a push hole 85 that cooperates with the push rod 45. The push rod 45 and the pushing member 39 can be threadedly connected. The push rod 45 extends to the outside of the limiting seat 37. A baffle 46 is provided at the closed opening 41 and can be connected to the limiting seat 37 via bolts.

[0053] A sliding chamber 47 is further provided in the movable area 40, and a sliding protrusion 48 is provided on the pusher 39 to cooperate with the sliding chamber 47. By limiting the position of the pusher 39 by the baffle 46, the sliding chamber 47 can be formed between the baffle 46 and the movable area 40, so that the sliding chamber 47 can limit the movement position of the pusher 39.

[0054] The position-limiting member 38 comprises a guide body 49 and a blocking body 50. A fixing hole 51 is provided in the center of the guide body 49. A spring 52 is disposed between the baffle 46 and the position-limiting member 38 and is disposed in the fixing hole 51. The position-limiting member 38 is provided with a guide slope 53 and a blocking surface 54, both of which are disposed on the blocking body 50. The blocking surface 54 is located below the guide slope 53. A limiting slope 55 is disposed in the connecting hole 42, cooperating with the guide slope 53 and limiting the movement of the position-limiting member 38.

[0055] The pusher 39 is provided with a symmetrically arranged guide oblique rod 56 , and the limiting member 38 is provided with a guide oblique groove 57 that cooperates with the guide oblique rod 56 . The limiting member 38 extends into the T-shaped groove 43 through the connecting hole 42 .

[0056] When installing the laser head 18, the T-shaped block 44 on the laser head 18 is directly matched with the T-shaped slot 43 and pressed downward. The guide inclined surface 53 is pushed by the T-shaped block 44, so that the limit member 38 pushes the spring 52 to compress, thereby causing the guide inclined slot 57 to drive the guide inclined rod 56 to move, and the push member 39 moves downward to achieve the locking positioning of the laser head 18.

[0057] When removing, just press the push rod 45, the guide inclined rod 56 moves in the guide inclined groove 57, and the sliding protrusion 48 moves downward in the sliding chamber 47, driving the limiter 38 to compress the spring 52, thereby taking out the laser head 18 for replacement and maintenance.

[0058] Example 3

[0059] If the fabric at the lower end is not completely cut, the laser head 18 needs to be replaced and the laser needs to be debugged. This can easily damage the fabric during debugging. After removing the laser head 18, its laser needs to be debugged. Since it's impossible for every laser head 18 to have exactly the same laser reflection angle, slight variations exist. Therefore, debugging is necessary after installation. During debugging, a debugging plate is typically placed on the third reflector (not shown) of the laser head 18, where the dimming assembly 58 is installed in this application. The dimming assembly 58 can rotate the dimming element 59 during laser debugging. The tilted dimming element 59 blocks the laser light, preventing it from striking the third reflector inside the laser head 18. This prevents the third reflector from transmitting the laser light to the focusing lens (not shown) inside the laser head 18, thus preventing the fabric at the lower end from being cut. Once debugging is complete, the dimming element 59 can be rotated in the opposite direction to ensure that the through hole 60 is horizontal, facilitating laser light exposure to the third reflector.

[0060] A laser tube 61, a first reflector 62 and a second reflector 63 are provided on the fixed frame 4. The laser is emitted from the laser tube 61, then reflected by the first reflector 62 to the second reflector 63, then reflected by the second reflector 63 to the third reflector in the laser head 18, then reflected to the focusing mirror, and finally irradiated onto the cloth to be cut.

[0061] The laser head 18 is provided with a mounting seat 64 and a connecting pipe 65. The connecting pipe 65 can be connected to the air pipe to blow up the lower end of the laser head 18, which can cool the cutting fabric below, cool the focusing lens inside the laser head 18, and prevent smoke and dust during laser cutting from entering the laser head 18 and affecting the accuracy of the laser head 18.

[0062] A light inlet 66 is provided on the mounting base 64, and a dimming component 58 is provided in the light inlet 66. The dimming component 58 consists of a dimming base 67 and a dimming element 59. A through area 68 is formed in the middle of the dimming base 67, and the dimming element 59 is hinged in the through area 68 through a hinge 69.

[0063] A blocking ring 70 is provided at one end of the through-region 68, located at the end with the dimming element 59, and is used to block the limiting body 71. A blocking block 72 is provided at the lower end of the blocking ring 70, and a first notch 73 and a second notch 74 are provided on the dimming seat 67. A first elastic arm 75 is provided in the first notch 73, and a first limiting head 76 is provided on the first elastic arm 75. A first limiting region 77 is formed between the first limiting head 76 and the blocking block 72. A second elastic arm 78 is provided in the second notch 74, and a second limiting head 79 is provided on the second elastic arm 78. A second limiting region 80 is formed between the second limiting head 79 and the blocking ring 70.

[0064] The dimming element 59 is composed of a rotating body 81, a rod 82, and a circular body 83. The circular body 83 is connected to the rotating body 81 through the rod 82. A through hole 60 is formed in the middle of the rotating body 81, the rod 82, and the circular body 83. The circular body 83 is provided with an arc surface 84. The arc surface 84 is a rough surface that does not reflect the laser. There is a gap between the rotating body 81 and the blocking ring 70, which facilitates the rotation of the rotating body 81, but does not allow the limiter 71 to be moved out. When installing the dimming element 59, first place the limiter 71 in the through area 68, then rotate it 90° so that it cooperates with the first limit area 77 or the second limit area 80, and then hinge the hinge 69 to the dimming element 59.

[0065] A limiting body 71 is provided on the side of the rotating body 81, which cooperates with the first limiting area 77 and the second limiting area 80. When the limiting body 71 is in the first limiting area 77, the through hole 60 is kept in an inclined state. When the limiting body 71 is in the second limiting area 80, the through hole 60 is kept in a horizontal state.

[0066] like Figure 16 As shown, the through hole 60 is in a horizontal state at this time, and the laser can pass through the through hole 60 and be reflected by the third reflector. Figure 17 As shown, the dimming element 59 is in a tilted state at this time, blocked by the blocking block 72, and the through hole 60 is in a tilted state, so that the laser reflected from the second reflector 63 can pass through the through hole 60 and illuminate the third reflector.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
