Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and more specifically to a laser penetration cutting device for multi-layer stacked profiles of a pallet frame. Background Technology

[0002] Pallets are devices used in logistics transportation for the containerization, stacking, handling and transport of goods. They are an important basic tool in the modern logistics system. Pallets are mainly composed of frames and support strips and are used to support goods. During the manufacturing process, a conveyor mechanism is used to smoothly transport the rolled sheet material along the track to the laser cutting processing area. During the conveying process, the sheet material is squeezed into a specified shape in the conveyor mechanism, and then the laser cutting equipment cuts the squeezed sheet material into the required length.

[0003] In existing technologies, after the raw material of the board is cut, the cut part falls directly to the ground. Since the cut part of the raw material is at a certain height from the ground, the edge of the raw material will be impacted, resulting in local dents or overall warping, which will affect subsequent assembly or flatness requirements. Furthermore, the cut raw material will be irregularly distributed on the ground, requiring manual collection, which may cause workers to be cut by the sharp edges of the cut raw material, posing a high safety hazard. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a laser penetration cutting device for multi-layer stacked profiles of pallet frames. This device effectively solves the problem in existing technologies where, after the sheet material is cut, the cut portion falls directly to the ground. Because the cut point of the sheet material is at a certain height from the ground, this height causes the edge of the sheet material to be impacted, resulting in local dents or overall warping, which affects subsequent assembly or flatness requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a laser penetration cutting device for multi-layer stacked profiles of pallet frames, comprising:

[0008] The conveying unit includes a feeding component for conveying sheet material, and a laser cutting component is fixedly connected to the discharge end of the feeding component;

[0009] The receiving section includes a collecting platform, which is located at the discharge end of the feeding component. A receiving frame is fixedly connected to the top of the collecting platform. A feeding plate that fits against the bottom of the receiving frame is slidably connected to the collecting platform via a slide rail base located on its top. A linkage component is provided at the bottom of the feeding plate. A rectangular hole is opened on the top of the collecting platform. A collecting rack for centralized storage of profiles is detachably installed on the bottom of the collecting platform. The collecting rack is located directly below the rectangular hole. A correction component for adjusting the position of the profiles is provided at the bottom of the collecting platform.

[0010] The rectangular hole is equipped with a material unloading component that can be used to support the profile.

[0011] Furthermore, the calibration component includes guide holes, which are opened on the top of the collection platform, and there are four guide holes. The collection platform is slidably connected to a movable frame that slides against the inner wall of the guide holes via a guide rail set at its bottom, and a calibration plate for adjusting the position of the profile is fixedly connected to the outside of the movable frame.

[0012] Furthermore, the calibration component also includes a drive mechanism, which includes a gear ring. The gear ring is rotatably connected to the bottom of the collection platform via an annular groove on its surface. A push block is fixedly connected to the inner wall of the gear ring. A bracket is fixedly connected to the bottom of the collection platform, and the adjacent surface of the bracket and the movable frame are connected by a spring. An abutment rod fixedly connected to the movable frame is slidably connected inside the bracket, and a ball block that fits against the outer circumference of the push block is fixedly connected to the end of the abutment rod away from the movable frame.

[0013] Furthermore, the linkage includes an L-shaped plate, which is fixedly connected to the bottom of the feeding plate, and a rack is fixedly connected to the side of the L-shaped plate away from the feeding plate.

[0014] Furthermore, a drive shaft is rotatably connected to the top of the collection platform near the rectangular hole, and a transmission gear that meshes with a rack is fixedly connected to the top of the drive shaft. A rotating shaft is rotatably connected to the bottom of the collection platform, and a drive gear that meshes with a gear ring is fixedly connected to the outer circumference of the rotating shaft. Pulleys are fixedly connected to the bottom of the drive shaft and the rotating shaft, and the two pulleys are connected by a synchronous belt.

[0015] Furthermore, the unloading component includes a fixed plate, which is fixedly connected to the side wall of the rectangular hole. There are four fixed plates. The fixed plate is slidably connected to a movable plate through a groove on its surface. The movable plate is connected to the bottom of the fixed plate through an elastic element at its bottom. The movable plate is slidably connected to a support plate through a slider at its top.

[0016] Furthermore, the fixed plate has a storage groove inside, and an electromagnetic block is fixedly connected to the side wall of the storage groove. The support plate is magnetically connected to the electromagnetic block on the side near the fixed plate.

[0017] The technical solution provided by this invention has the following advantages compared with the prior art:

[0018] This invention features a collection section. The cut sheet material first falls onto a feeding plate, and then, through the cooperation of the feeding plate and the abutment frame, the sheet material is pushed onto the collection platform by support bars. This prevents the cut sheet material from directly impacting the ground, which could cause localized dents or overall warping at the edges, affecting later use. This effectively protects the integrity and quality of the sheet material. Furthermore, a correction component aligns the cut sheet material, ensuring it is stacked orderly on the unloading component, preventing random distribution. This orderly collection method facilitates sorting and handling by workers, improving work efficiency. Simultaneously, the orderly stacking also promotes efficient use of space, making the collection area cleaner and more standardized. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to embodiments. Example

[0032] Please see Figures 1-9 This invention provides a technical solution: a laser penetration cutting device for multi-layer stacked profiles of pallet frames, comprising:

[0033] The conveying unit 1 includes a feeding component 11 for conveying sheet material, and a laser cutting component 12 is fixedly connected to the discharge end of the feeding component 11.

[0034] The receiving section 2 includes a collecting platform 21, which is located at the discharge end of the feeding component 11. A contact frame 22 is fixedly connected to the top of the collecting platform 21. A feeding plate 24 that fits against the bottom of the contact frame 22 is slidably connected to the collecting platform 21 via a slide rail base 23 located on its top. A linkage component 25 is provided at the bottom of the feeding plate 24. A rectangular hole 26 is provided on the top of the collecting platform 21. A collecting rack 27 for centralized storage of profiles is detachably installed on the bottom of the collecting platform 21. The collecting rack 27 is located directly below the rectangular hole 26. A correction component 28 for adjusting the position of the profiles is provided at the bottom of the collecting platform 21.

[0035] The rectangular hole 26 contains a discharge part 29 that can be used to support the profile.

[0036] The calibration component 28 includes guide holes 281, which are opened on the top of the collection platform 21. There are four guide holes 281. The collection platform 21 is slidably connected to a movable frame 282 that slides against the inner wall of the guide holes 281 via a guide rail at its bottom. A calibration plate 283 for adjusting the position of the profile is fixedly connected to the outside of the movable frame 282.

[0037] The calibration component 28 also includes a drive mechanism 284, which includes a gear ring 2841. The gear ring 2841 is rotatably connected to the bottom of the collection platform 21 through an annular groove on its surface. A push block 2842 is fixedly connected to the inner wall of the gear ring 2841. A bracket 2843 is fixedly connected to the bottom of the collection platform 21, and the adjacent surface of the bracket 2843 and the movable frame 282 are connected by a spring. An abutment rod 2844, which is fixedly connected to the movable frame 282, is slidably connected inside the bracket 2843. A ball block 2845, which is in contact with the outer circumference of the push block 2842, is fixedly connected to the end of the abutment rod 2844 away from the movable frame 282.

[0038] The linkage component 25 includes an L-shaped plate 251, which is fixedly connected to the bottom of the feeding plate 24. A rack 252 is fixedly connected to the side of the L-shaped plate 251 away from the feeding plate 24.

[0039] A drive shaft 253 is rotatably connected to the top of the collection platform 21 near the rectangular hole 26, and a transmission gear 254 that meshes with a rack 252 is fixedly connected to the top of the drive shaft 253. A rotating shaft 255 is rotatably connected to the bottom of the collection platform 21, and a drive gear 256 that meshes with a gear ring 2841 is fixedly connected to the outer circumference of the rotating shaft 255. Pulleys 257 are fixedly connected to the bottom of the drive shaft 253 and the rotating shaft 255, and the two pulleys 257 are connected to each other by a synchronous belt 258.

[0040] The unloading component 29 includes a fixed plate 291, which is fixedly connected to the side wall of the rectangular hole 26. There are four fixed plates 291. The fixed plates 291 are slidably connected to the movable plates 292 through the sliding grooves provided on their surfaces. The movable plates 292 are connected to the bottom of the fixed plates 291 through the elastic members 293 provided at their bottoms. The movable plates 292 are slidably connected to the support plate 294 through the sliders provided at their tops.

[0041] The fixed plate 291 has a storage slot 295 inside, and an electromagnetic block 296 is fixedly connected to the side wall of the storage slot 295. The support plate 294 is magnetically connected to the electromagnetic block 296 on the side near the fixed plate 291.

[0042] The cutting process of sheet material:

[0043] Initially, the sheet material is wound on the external feeding frame. One end of the sheet material is placed into the feeding component 11, and the feeding component 11 is started. In conjunction with its internal multiple sets of feeding rollers (each set has two rollers, which rotate synchronously in opposite directions to move the sheet material), the sheet material is gradually fed to the laser cutting component 12. While conveying the sheet material, the feeding rollers can press the sheet material into a certain shape. When the sheet material passes through the laser cutting component 12, the laser cutting component 12 cuts the sheet material to the required length.

[0044] When the laser cutting component 12 is not cutting the sheet material, the slide rail base 23 will move the feeding plate 24 at a constant speed until the feeding plate 24 exceeds the abutment frame 22. When the sheet material is being cut, it will gradually tilt downwards (away from the laser cutting component 12) under its own gravity until the sheet material (away from the laser cutting component 12) contacts the feeding plate 24. As the feeding plate 24 continues to move, it will drive the cut sheet material to move synchronously until the cut sheet material is completely on top of the feeding plate 24. Control the slide rail base 23 to drive the feeding plate 24 to move in the opposite direction. When the sheet material on top of the feeding plate 24 contacts the abutment frame 22, the abutment frame 22 will prevent the sheet material from moving with the feeding plate 24. As a result, the support bar will be pushed down onto the collection table 21 by the abutment frame 22. This can prevent the cut sheet material from falling directly to the ground, causing the edge of the sheet material to be impacted, resulting in local dents or overall warping, which would affect its later use.

[0045] The process of adjusting the position of the raw material of the board:

[0046] When the feeding plate 24 moves away from the feeding component 11, the L-shaped plate 251 at the bottom of the feeding plate 24 will drive the rack 252 to move synchronously. Since the rack 252 meshes with the transmission gear 254, the transmission gear 254 will drive the drive shaft 253 to rotate synchronously. With the help of the pulley 257, the timing belt 258 and the rotating shaft 255, the drive gear 256 can drive the gear ring 2841 to rotate. As the gear ring 2841 rotates at a constant speed, the push block 2842 (the push block 2842 has an outward convex arc design) will gradually reduce the pressure on the abutment rod 2844. The bracket 2843 and the moving frame 282 are connected by a spring, so the moving frame 282 will gradually return to its original position along the guide hole 281 until the moving frame 282 is in its initial position. At this time, the distance between the correction plate 283 and the side wall of the rectangular hole 26 is the largest. With the assistance of the feeding plate 24, the sheet material enters the space enclosed by the four correction plates 283. As the feeding plate 24 resets, the L-shaped plate 251, rack 252, transmission gear 254, drive shaft 253, pulley 257, synchronous belt 258, and rotating shaft 255 enable the drive gear 256 to rotate the gear ring 2841. Consequently, the push block 2842 gradually increases its pressure on the abutment rod 2844, allowing the abutment rod 2844 to drive the moving frame 282 to move along the guide hole 281 toward the sheet material. The four moving frames 282 move synchronously, adjusting the position of the sheet material so that it is centered in the rectangular hole 26, thus achieving the correction of the sheet material. This process is repeated, ensuring that each cut sheet material is stacked in an orderly manner, avoiding random distribution and the need for manual collection. It also prevents workers from touching the sharp edges of the cut sheet material, reducing safety hazards.

[0047] It is worth noting that there are four guide holes 281, which are located on the top of the collection platform 21. The center line of each guide hole 281 coincides with the center line of the side wall of the corresponding rectangular hole 26. This allows the four moving frames 282 to drive the correction plates 283 to correct the material from all sides, ensuring that the material is centered in the rectangular hole 26. Rubber pads are provided on the side of the correction plates 283 closest to the material to buffer the material when it comes into contact with the correction plates 283, preventing excessive clamping force and deformation of the material. The four abutment rods 2844 are divided into two groups. One group of abutment rods 2844 is longer, and the other group is shorter. The longer group is located near the longer side wall of the rectangular hole 26, and the shorter group is located near the longer side wall of the rectangular hole 26. This ensures that when the gear ring 2841 rotates, the abutment rods 2844 can drive the corresponding moving frame 282 to move the same distance along the guide hole 281. This ensures that the four correction plates 283 move towards the material at the same time, which is beneficial for correcting the position of the material after cutting and avoiding its random distribution.

[0048] The process of centralized collection of raw materials for wood panels:

[0049] As the feeding plate 24 moves back and forth, multiple cut sheet materials can be moved to the vicinity of the rectangular hole 26. Furthermore, the correction component 28 will correct each cut sheet material, so that each cut sheet material will be stacked in an orderly manner on the unloading component 29.

[0050] In the initial state, the elastic element 293 will maintain a balanced state with the movable plate 292 and the support plate 294. At this time, the support plate 294 is flush with the collection platform 21. When the material of the board starts to accumulate on the surface of the support plate 294, the weight of the material of the board itself will disrupt the balance between the movable plate 292, the support plate 294 and the elastic element 293. The material of the board, the movable plate 292 and the support plate 294 will slightly compress the elastic element 293, so that it returns to a balanced state. This process repeats until a certain amount of board material accumulates on the surface of the support plate 294. At this time, the movable plate 292 will move the support plate 294 to the position of the storage slot 295. Since the support plate 294 and the electromagnetic block 296 in the storage slot 295 are connected by magnetic force, the magnetic force generated by the electromagnetic block 296 will attract the support plate 294 into the storage slot 295, causing the accumulated board material to lose support and fall into the collection rack 27. This process repeats until the collection rack 27 is full of board material.

[0051] It is worth noting that the size of the storage slot 295 is slightly larger than that of the support plate 294, which facilitates the smooth entry of the support plate 294 into the storage slot 295. The number of support plates 294 can be set as needed; four are selected here, and the four support plates 294 are divided into two groups, each group consisting of two support plates 294. The two support plates 294 are symmetrically distributed along the center of the longer sidewall of the rectangular hole 26, which increases the stability of the stacked board material. The size of the collection rack 27 is adapted to the required cutting length of the board material, preventing the cut board material from being misplaced after entering the collection rack 27.

[0052] In summary, the present invention, by employing a collection unit and a conveying unit 1, has the following advantages:

[0053] Firstly, after the laser cutting part 12 finishes cutting the sheet material, the cut sheet material first falls onto the feeding plate 24. Then, through the cooperation between the feeding plate 24 and the abutment frame 22, the sheet material is pushed down onto the collection table 21 by the support strip. This avoids the sheet material from directly impacting the ground after cutting, which could cause the edges of the sheet material to be impacted, resulting in local dents or overall warping, affecting later use and effectively protecting the integrity and quality of the sheet material.

[0054] Secondly, the alignment component 28 aligns the cut sheet material, allowing it to be stacked orderly on the unloading component 29, thus avoiding random distribution of the sheet material. This orderly collection method facilitates the sorting and handling by staff, improving work efficiency. At the same time, orderly stacking also helps to make reasonable use of space, making the collection area cleaner and more standardized.

[0055] Thirdly, the cooperation of the movable plate 292, the support plate 294 and the elastic element 293, as well as the adsorption effect of the electromagnetic block 296, allows the support plate 294 to automatically move to the storage trough 295 after a certain amount of board material has accumulated on its surface, unloading the board material into the collection rack 27. This enables centralized collection of board material, reduces manual intervention, and lowers labor intensity.

[0056] Fourthly, when the raw materials on the support plate 294 accumulate to a certain weight, gravity will cause the movable plate 292 to move the support plate 294, so that the accumulated raw materials will fall into the collection rack 27. Since the raw materials cut in the same batch are of the same length, the number of raw materials carried by the support plate 294 each time is relatively fixed, and they are released in batches, which improves the counting efficiency and achieves accurate statistics on the number of raw materials after cutting.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
