Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to an adsorption structure for a rotary cutting platform. Background Technology

[0002] Laser cutting uses a focusing lens to focus a laser beam onto the surface of the material to be cut, melting the material. Simultaneously, compressed gas, coaxial with the laser beam, blows away the molten material, causing the laser beam and material to move relative to each other along a specific trajectory, thus creating a cut of a certain shape. Laser cutting technology is widely used in the processing of both metallic and non-metallic materials, significantly reducing processing time, lowering costs, and improving workpiece quality.

[0003] The adsorption mechanisms of commercially available laser cutting machines are all fixedly installed below the cutting platform. Their design is only compatible with traditional, fixed cutting platforms (i.e., the cutting platform is permanently set up) and is difficult to adapt to newer cutting platforms with variable shapes. As processing demands upgrade, conventional, fixed cutting platforms can no longer meet the needs of some high-quality processing scenarios, such as single-sided laser processing of semi-finished garments (e.g., opening holes, adding logos). These requirements necessitate platforms with flexible functions such as rotation and angle adjustment to achieve precise positioning and single-sided cutting, avoiding accidental cuts and damage. Therefore, it is necessary to develop new cutting platforms with rotatable or other variable shapes. Traditional fixed adsorption mechanisms cannot adapt to the platform's rotational movements, failing to guarantee adsorption stability during dynamic processes, thus affecting cutting accuracy. Therefore, a new adsorption structure for a matching rotating cutting platform also needs to be developed simultaneously. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] like Figure 1-7 As shown, the present invention provides an adsorption structure for a rotary cutting platform, including a drive mechanism, a main frame 1, a cutting platform 2, and an air suction pipe 4.

[0020] The main frame 1 is provided with a cutting space 11, wherein the drive mechanism is located on one side of the cutting space 11.

[0021] The cutting platform 2 is located within the cutting space 11 and below the laser head 3 of the laser cutting machine. One end of the cutting platform 2 is connected to the drive mechanism, which drives the cutting platform 2 to rotate. It should be understood that the semi-finished garment is placed inside the cutting platform 2, and then the laser head 3 of the laser cutting machine performs laser cutting on the semi-finished garment. Simultaneously, the drive mechanism can drive the cutting platform 2 and the semi-finished garment to rotate, cooperating with the laser head 3 of the laser cutting machine to perform laser cutting on the semi-finished garment.

[0022] Of course, the above example only uses semi-finished clothing as the item to be cut, but other double-layered items that need to be cut into single layers can also be cut in this way.

[0023] One end of the suction pipe 4 is connected to the exhaust fan, and the other end is connected to the cutting platform 2, so that the exhaust fan can remove waste material from the cutting platform 2 through the suction pipe 4. It should be understood that the exhaust fan draws air from the cutting platform 2 through the suction pipe 4, causing the semi-finished garments to adhere to the cutting platform 2. This ensures the semi-finished garments are firmly fixed in the cutting platform 2 during rotation, thereby guaranteeing the precision of laser cutting. The connection between the suction pipe 4 and the exhaust fan is rotatable, allowing the cutting platform 2 to rotate.

[0024] In this embodiment, the cutting platform 2 includes a support frame 21, a mesh plate 22, a lower mesh plate 23, and a partition 24. The support frame 21 has a hollow inner cavity that communicates with the other end of the suction pipe 4. The mesh plate 22 is located at the top of the hollow inner cavity, the lower mesh plate 23 is located at the bottom of the hollow inner cavity, and the partition 24 is located at the center of the hollow inner cavity, dividing the hollow inner cavity into a first hollow inner cavity that communicates with the other end of the suction pipe 4 and a second hollow inner cavity that communicates with the other end of the suction pipe. It should be understood that in this embodiment, the support frame 21, the mesh plate 22, and the partition 24 form the first hollow inner cavity, and the support frame 21, the lower mesh plate 23, and the partition 24 form the second hollow inner cavity. The other end of the suction pipe communicates with both the first and second hollow inner cavities.

[0025] It should be understood that when the semi-finished garment is placed on the cutting platform 2, it comes into contact with the support frame 21, the mesh plate 22, and the lower mesh plate 23. During laser cutting, when the mesh plate 22 is on the top surface, the laser beam cuts the object to be cut on the mesh plate 22, and the waste material leaks into the first hollow inner cavity and is sucked away by the suction pipe 4. When the lower mesh plate 23 is on the top surface, the laser beam cuts the object to be cut on the lower mesh plate 23, and the waste material leaks into the second hollow inner cavity and is sucked away by the suction pipe 4. This solves the problem that the traditional fixed adsorption mechanism cannot adapt to the rotation of the platform and cannot guarantee the adsorption stability during the dynamic process, thus affecting the cutting accuracy.

[0026] Preferably, the support frame 21 is rectangular, the hollow cavity is rectangular, the partition 24 is rectangular, and both the upper mesh plate 22 and the lower mesh plate 23 are rectangular. The length and width of the upper mesh plate 22 are equal to the length and width of the lower mesh plate 23, the length and width of the partition 24 are equal to or greater than the length and width of the hollow cavity, and the length and width of the upper mesh plate 22 are equal to the length and width of the hollow cavity. It should be understood that the rectangular shape of the support frame 21 conforms to the shape of the semi-finished garment, resulting in a smaller distance between the semi-finished garment and the support frame 21, upper mesh plate 22, and lower mesh plate 23 after it is placed on the cutting platform 2, facilitating adsorption and reducing the likelihood of wrinkles after adsorption.

[0027] It should be understood that in this embodiment, both the upper mesh plate 22 and the lower mesh plate 23 are rectangular three-dimensional, and the mesh holes of the upper mesh plate 22 and the lower mesh plate 23 are rectangular three-dimensional, that is, the mesh holes of the upper mesh plate 22 and the lower mesh plate 23 have a certain depth, so that the waste material to be cut placed on the upper mesh plate 22 and the lower mesh plate 23 is fed into the hollow inner cavity through its mesh holes.

[0028] Furthermore, a first side plate 111 and a second side plate 112 are spaced apart on one side wall of the hollow inner cavity, and a third side plate 113 and a fourth side plate 114 are spaced apart on the other side wall of the hollow inner cavity. A first clamping groove 11a is formed between the first side plate 111 and the second side plate 112, and a second clamping groove 11b is formed between the third side plate 113 and the fourth side plate 114. One end of the partition 24 is disposed in the first clamping groove 11a, and the other end of the partition 24 is disposed in the second clamping groove 11b. It should be understood that by setting the first side plate 111 and the second side plate 112 to hold one end of the partition 24 in place, and by setting the third side plate 113 and the fourth side plate 114 to hold the other end of the partition 24 in place, the placement of the partition 24 can be further stabilized.

[0029] Preferably, a plurality of first support bars 101 are provided in the first hollow inner cavity, and the upper mesh plate is connected to the plurality of first support bars 101. A plurality of second support bars 102 are provided in the second hollow inner cavity, and the lower mesh plate 23 is connected to the plurality of second support bars 102. It should be understood that the first support bars 101 and the second support bars 102 are fixedly arranged in the hollow inner cavity along the direction of the suction pipe, which can stabilize the upper mesh plate 22 and the lower mesh plate 23.

[0030] In this embodiment, a front side plate 201 is provided at the front end of the hollow inner cavity. The front side plate 201 has a first through hole 201a communicating with the hollow inner cavity. A connecting plate 202 is provided on the side of the front side plate 201 away from the hollow inner cavity. The connecting plate 202 has a second through hole 202a corresponding to the first through hole 201. The other end of the suction pipe 4 is connected to the connecting plate 202 and communicates with the second through hole 202a. It should be understood that when the exhaust fan is drawing air, the hollow inner cavity is drawn through the suction pipe 4, the second through hole 202a of the connecting plate 202, and the first through hole 201a of the front side plate 201 in sequence.

[0031] Preferably, the first through hole 201a is circular, with the partition 24 disposed at the center of the first through hole 201a. It should be understood that the partition 24 divides the first through hole 201a into two half-holes of equal size, one half-hole communicating with the first hollow inner cavity and the other half-hole communicating with the second hollow inner cavity. The partition 24 being disposed at the center of the first through hole 201a also ensures that the suction force of the first central inner cavity and the second central inner cavity is the same.

[0032] Specifically, the front side plate 201 has multiple blind holes spaced apart on the side away from the hollow inner cavity, and the connecting plate 202 has multiple third through holes 202b spaced apart, corresponding to the blind holes. Both the blind holes and the third through holes 202b have internal threads, and a first screw is threaded into both the third through holes 202b and the blind holes. It should be understood that the internal threads in the blind holes and the third through holes 202b, combined with the first screws, tightly fix the front side plate 201 and the connecting plate 202 together, ensuring no gaps between the first through holes 201a and the second through holes 202b, thus guaranteeing suction.

[0033] Of course, a sealing gasket is also provided between the front side panel 201 and the connecting plate 202 to provide a seal.

[0034] Furthermore, the other end of the suction pipe 4 is provided with a connecting flange 41, which has a plurality of first threaded holes 41a spaced apart. The outer side of the second through hole 202a of the connecting plate has second threaded holes 202c corresponding to the plurality of first threaded holes 41a spaced apart. Second screws are threadedly connected to the second threaded holes 202c and the first threaded holes 41a. It should be understood that the first threaded holes 41a and the second threaded holes 202c are fixed by the second screws to avoid gaps and ensure suction force.

[0035] Preferably, the side of the connecting plate 202 away from the front side plate 201 is provided with a first receiving groove 202d with a diameter larger than that of the second through hole 202a, and the connecting flange 41 is located in the first receiving groove 202d. The other side of the connecting plate 202 near the front side plate 201 is provided with a second receiving groove 202e located outside the second through hole 201a. The second threaded hole 202c is located in the second receiving groove 202e, and the second threaded hole 202v is also located in the first receiving groove 202d. It should be understood that the connecting flange 41 is fitted into the first receiving groove 202d (i.e., the outer diameter of the connecting flange 41 is equal to the diameter of the hole in the first receiving groove 202d), so that the first receiving groove 202d holds the connecting flange 41, which can improve the sealing effect. The second threaded hole 202c is also set in the first receiving groove 202d, so that the first threaded hole 41a and the second threaded hole 202c are connected, and the second screw has penetrated the connecting plate 202, so that the connecting flange 41 and the connecting plate 202 are fixed together, making the fixation more stable and tight.

[0036] Preferably, the driving mechanism includes a stepper motor 6 and a support rod 5. The support rod 5 is vertically positioned on one side of the cutting space 11. The top of the support rod 5 has a through hole into which a bearing is installed. The stepper motor 6 is housed within the support rod 5, and the suction pipe 4 passes through the bearing. A rack is arranged around the outer wall of the suction pipe 4, and the rotating shaft of the stepper motor 6 is equipped with a gear that meshes with the rack. It should be understood that when the cutting platform 2 needs to rotate, the stepper motor 6 drives the suction pipe 4 to rotate on the bearing of the support rod 5 via the gear and rack, simultaneously causing the cutting platform 2 to rotate.

[0037] It is worth noting that in this embodiment, a controller is connected to the side wall of the main frame 1, and the controller is electrically connected to the laser head 3, the stepper motor 6 and the exhaust fan of the laser cutting machine, and controls them to work through the controller.
