Description

A short material receiving rack Technical Field

[0001] This utility model relates to the field of pipe cutting machine technology, and in particular to a short material receiving rack. Background Technology

[0002] Laser tube cutting machines, as high-precision tube processing equipment, are widely used in the fields of irregular cutting, hole drilling, and segmentation of metal tubes. This equipment is typically equipped with upper and lower synchronous moving support plates, which dynamically support the tube body in real time during the cutting process, effectively preventing sagging and deformation caused by gravity, thereby ensuring the perpendicularity and dimensional accuracy of the cut surface.

[0003] In actual operation, the cut short tubes slide down the surface of the support plate to the collection area. In traditional solutions, an open hopper is installed below the support plate to catch the falling short tubes. Due to the limited width of the support plate, the hopper must be placed close to the high-temperature working area of ​​the laser cutting head. Operators must frequently enter the high-temperature radiation zone and the area where metal debris flies, manually moving the full hopper and replacing the empty hopper, posing a safety hazard of burns and skin damage.

[0004] To address these issues, existing technologies propose adding a receiving rack between the support plate and the hopper. This rack continuously transports short pieces of material to a hopper located away from the cutting station via a circulating receiving plate. However, this solution still has significant drawbacks: metal generated during cutting easily adheres to the surface of the receiving plate, forming a hardened layer. This hardened layer has a rough surface that easily scratches the surface of the short pieces, thus affecting their surface quality. Therefore, operators need to periodically clean debris from the surface of the receiving plate 25, adding extra maintenance workload.

[0005] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a short material receiving rack, which aims to solve the technical problem that the surface debris of the receiving plate cannot be cleaned by itself, resulting in the formation of a slab layer and causing scratches on the surface of the short material.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A short material receiving rack, comprising:

[0009] frame;

[0010] The conveying mechanism, mounted on the frame, includes several receiving plates that circulate and are used to receive and convey short materials forward.

[0015] Two chip collection trays are located on both sides of the first support.

[0016] Furthermore, the conveying mechanism includes two rotating shafts rotatably connected to the frame, two sets of sprockets respectively connected to the two rotating shafts, two chains sleeved between the corresponding sprockets, and a first drive motor mounted on the frame. The first drive motor drives any one of the rotating shafts to rotate, and multiple receiving plates are straddling between the two chains.

[0017] Furthermore, the cross-section of the receiving plate has a V-shaped structure.

[0018] Furthermore, it also includes an inverted V-shaped chip guide plate, which is located between the brush and the bottom of the second support; a brush is provided on the top of the chip guide plate, and the brush contacts the bottom circumference of the brush.

[0019] Furthermore, the rotating mechanism includes a second drive motor, a synchronous belt drive assembly, and a protective cover. The second drive motor is located at the bottom of the second bracket and drives the brush to rotate through the synchronous belt drive assembly. The protective cover is located at the end of the second bracket and covers the synchronous belt drive assembly.

[0020] Furthermore, two adapters are rotatably connected to the second bracket, each adapter having a U-shaped seat. The end of the brush is inserted into the U-shaped seat and locked by a set screw.

[0021] Furthermore, the translation mechanism includes a third drive motor, an eccentric disk, and a vertical rod. The third drive motor is mounted on the first support. The eccentric disk includes a turntable connected to the motor shaft of the third drive motor and a lever located on the edge of the turntable. The vertical rod is located at the bottom of the second support and has a vertically extending sliding groove. The lever is slidably connected to the sliding groove.

[0022] Furthermore, a roller is rotatably connected to the lever, and the roller is embedded in a groove.

[0023] Furthermore, it also includes a plurality of first height adjustment feet. The first bracket is provided with a plurality of U-shaped notches. The first height adjustment feet include foot cups provided in the U-shaped notches and two height adjustment nuts screwed to the foot cups. The U-shaped notches are located between the two height adjustment nuts.

[0024] Furthermore, it also includes several casters located at the bottom of the first bracket, with the installation height of the casters being higher than the installation height of the first adjustable feet.

[0025] Beneficial effects:

[0026] This utility model provides a short material receiving rack, in which a conveying mechanism drives multiple receiving plates to circulate. When the plate reaches the upper straight section, it receives and conveys the short material forward.

Detailed Implementation

[0036] This utility model provides a short material receiving rack. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0038] Please refer to Figures 1 to 8. This utility model provides a short material receiving rack, which is located below the follow-up support plate a, and is used to receive and transport short materials forward. The short material receiving rack includes: a frame 1, a conveying mechanism 2, a first support 3, a translation mechanism 4, a second support 5, a brush 6, and two chip collection discs 8; the conveying mechanism 2 is mounted on the frame 1 and includes several receiving plates 25 that circulate, the receiving plates 25 being used to receive and convey short materials forward; the first support 3 is located below the conveying mechanism 2; the translation mechanism 4 is mounted on the first support 3; the second support 5 is slidably connected to the first support 3, and the output end of the translation mechanism 4 is connected to the second support 5 to drive it to reciprocate along the length of the receiving plate 25; the brush 6 is rotatably mounted on the second support 5, and the second support 5 is provided with a rotating mechanism 7, the output end of the rotating mechanism 7 being connected to the brush 6; the two chip collection discs 8 are respectively located on both sides of the first support 3, and the chip collection discs 8 are used to collect the debris scraped off the surface of the receiving plate 25 by the brush 6.

[0039] During operation, after the short material self-following support plate a slides down, it is received by the circulating receiving plate 25 on the conveying mechanism 2. The conveying mechanism 2 drives multiple receiving plates 25 to circulate, and the short material is smoothly conveyed forward by the continuous circulating motion of the receiving plates 25. When the receiving plate 25 is in the upper straight section of the conveying mechanism 2, it conveys the short material forward. When the receiving plate 25 moves to the lower straight section of the conveying mechanism 2, the translation mechanism 4 drives the second bracket 5 to reciprocate along the length of the receiving plate 25. At the same time, the rotation mechanism 7 drives the brush 6 to rotate around its own axis, so that the brush 6 fully covers and scrapes the surface of the receiving plate 25 located in the lower straight section, thoroughly removing the adhering metal debris. The removed debris falls directly into the chip collection trays 8 on both sides under the action of gravity and is collected, realizing the synchronous self-cleaning of debris on the surface of the receiving plate 25.

[0040] The combined rotation and reciprocating translational motion of the brush 6 effectively prevents debris from adhering and caking on the surface of the receiving plate 25, thus eliminating surface scratches caused by friction between the rough surface of the caking layer and short materials. Simultaneously, the debris removal process operates in conjunction with the short material conveying operation, allowing for cleaning and maintenance of the receiving plate 25 without machine downtime. Furthermore, the debris collection disc 8 further reduces debris falling to the ground.

[0041] Preferably, the surface of the brush 6 is provided with multiple bundles of stainless steel wires, which are arranged in a spiral pattern on the outer periphery of the brush 6. This arrangement enhances the brush 6's ability to peel off debris while reducing wear on the surface of the mating plate 25.

[0042] In a preferred embodiment, referring to Figures 1 and 3, the conveying mechanism 2 includes two rotating shafts 21 rotatably connected to the frame 1, two sets of sprockets 22 respectively connected to the two rotating shafts 21, two chains 23 sleeved between the corresponding sprockets 22, and a first drive motor 24 mounted on the frame 1. The first drive motor 24 drives any one of the rotating shafts 21 to rotate, and multiple receiving plates 25 are straddling the two chains 23. Specifically, a reducer and a belt drive assembly are provided between the first drive motor 24 and any one of the rotating shafts 21. The first drive motor 24 drives the rotating shaft 21 to rotate at a constant speed through the reducer and belt drive assembly, driving the two sets of sprockets 22 to rotate synchronously, thereby driving the two chains 23 to perform a closed loop motion. The multiple receiving plates 25 straddling the two chains 23 thus form a continuous circulating conveying path, receiving falling short materials in the upper straight section of the conveying mechanism 2 and moving them forward smoothly, naturally transitioning to the lower straight section when the chains 23 turn.

[0043] Furthermore, referring to Figure 4, the receiving plate 25 has a V-shaped cross-section. When the short material slides down the follower support plate to the receiving frame, the V-shaped receiving plate 25 guides and limits the short material through its inclined surfaces on both sides. The geometric constraint characteristics of the V-shaped structure increase the static friction between the short material and the receiving plate 25, effectively suppressing the continuous rolling of the short material due to inertia or vibration during the conveying process, and buffering the rapid rolling of the short material.

[0044] In a preferred embodiment, referring to FIG4, it further includes an inverted V-shaped chip guide plate 9, which is disposed between the brush 6 and the bottom of the second support 5. When the brush 6 rotates to scrape off the debris on the surface of the receiving plate 25, some tiny debris is easily splashed to the bottom area of ​​the second support 5 by the centrifugal motion of the stainless steel wire bundle. After the splashed debris comes into contact with the chip guide plate 9, it is guided and slid down along the inclined surfaces on both sides into the chip collection tray 8, effectively preventing the deposition of debris on the second support 5.

[0045] In the above embodiments, referring to Figures 5 and 6, the bottom of the second support 5 is provided with two parallel guide rails 54, and the top of the first support 3 is provided with several sliders 55. At least two sliders 55 are slidably connected to one guide rail 54 to achieve stable support and sliding connection between the first support 3 and the second support 5. The chip guide plates 9 extend to the outside of the second support 5 on both sides, which acts as a shield for the guide rails 54 to prevent debris from splashing onto the guide rails 54 and thus disrupting the sliding between the guide rails 54 and the sliders.

[0046] As shown in Figures 6 and 7, a brush 10 is provided at the top of the chip guide plate 9. The brush 10 contacts the bottom circumferential surface of the brush 6. Specifically, a mounting groove 91 is provided at the top edge of the chip guide plate 9, and the brush 10 is detachably installed in the mounting groove 91. The brush 10 is in continuous contact with the stainless steel wire bundle on the brush 6. During the rotation of the brush 6, stubborn debris adhering to the stainless steel wire bundle is peeled off, avoiding secondary contamination of the surface of the receiving plate 25. The cleaning of the receiving plate 25 by the brush 6 and the cleaning of the brush 6 by the brush 10 not only ensures that there is no residue on the surface of the receiving plate 25, but also maintains the long-term stability of the cleaning efficiency of the brush 6 by inhibiting the adhesion of debris on the brush 6 itself, significantly extending the maintenance cycle.

[0047] Preferably, the brush 10 is provided with a plurality of nylon filament bundles arranged at equal intervals. When the nylon filament bundles come into contact with the stainless steel filament bundles of the brush 6, flexible interference is generated, which can effectively remove debris and avoid rigid scraping that could cause the filament bundles of the brush 6 to break.

[0048] In a preferred embodiment, referring to Figures 6 and 7, the rotating mechanism 7 includes a second drive motor 71, a synchronous belt drive assembly 72, and a protective cover 73. The second drive motor 71 is located at the bottom of the second support 5 and drives the brush 6 to rotate via the synchronous belt drive assembly 72. The protective cover 73 is located at the end of the second support 5 and covers the synchronous belt drive assembly 72. Preferably, the second drive motor 71 is a servo motor. The synchronous belt drive assembly 72 includes a drive wheel 721 mounted on the motor shaft of the second drive motor 71, a driven wheel 722 located at the end of the brush 6, and a synchronous belt 723 sleeved between the drive wheel 721 and the driven wheel 722. The second drive motor 71 drives the drive wheel 721 to rotate, and the drive wheel 721 drives the driven wheel 722 to rotate synchronously via the synchronous belt 723, thereby driving the brush 6 to rotate.

[0049] In addition, a protective cover 73 is installed to completely enclose the synchronous belt drive assembly 72 at the end of the second bracket 5, effectively preventing splashed debris from entering the pulley meshing area and avoiding transmission slippage or tooth skipping caused by debris jamming, thus ensuring the long-term reliability of the transmission structure.

[0050] In a preferred embodiment, referring to Figures 6 and 8, two adapters 51 are rotatably connected to the second bracket 5. Each adapter 51 is provided with a U-shaped seat 52, and the end of the brush 6 is inserted into the U-shaped seat 52 and locked by a set screw 53. When the stainless steel wire bundle of the brush 6 wears due to long-term use, the operator only needs to unscrew the set screw 53 on the adapter 51 to remove the end of the brush 6 from the U-shaped seat 52, quickly completing the disassembly of the old brush and the installation of the new brush.

[0051] Specifically, the side wall of the U-shaped seat 52 has a positioning hole 521, and the end of the brush 6 has a screw hole 522 corresponding to the position of the positioning hole 521. The set screw 53 passes through the positioning hole 521 and is screwed into the screw hole 522 to lock the position of the brush 6. The precise alignment design of the positioning hole 521 on the side wall of the U-shaped seat 52 and the screw hole 522 at the end of the brush 6 ensures that the axial coaxiality can be restored without complicated adjustments after the new brush 6 is inserted.

[0052] Specifically, as shown in Figure 8, the two side walls of the U-shaped seat 52 are respectively provided with coaxially arranged positioning holes 521 and screw holes 522. The end of the brush 6 is provided with a through hole 61 corresponding to the position of the positioning hole 521. The set screw 53 passes through the positioning hole 521 and the through hole 61 in sequence and is screwed into the screw hole 522 to lock the position of the brush 6. Since the set screw 53 passes through the end of the brush 6, it can effectively suppress the radial movement of the brush 6 during operation.

[0053] In a preferred embodiment, referring to Figures 4, 6, and 7, the translation mechanism 4 includes a third drive motor 41, an eccentric disk 42, and a vertical rod 43. The third drive motor 41 is mounted on the first support 3. The eccentric disk 42 includes a turntable 421 connected to the motor shaft of the third drive motor 41 and a lever 422 located on the edge of the turntable 421. The vertical rod 43 is located at the bottom of the second support 5 and has a vertically extending groove 431. The lever 422 is slidably connected to the groove 431. The third drive motor 41 is a servo motor, which drives the turntable 421 to rotate at a constant speed, causing the lever 422, fixed to the edge of the turntable 421, to perform circular motion around the rotation axis. The lever 422 is embedded in the groove 431 of the vertical rod 43, forming a dynamic sliding fit with the groove 431 during rotation, converting the rotational motion of the eccentric disk 42 into the periodic vertical displacement of the vertical rod 43. Because the vertical rod 43 is rigidly connected to the second support 5, the vertical displacement is further converted into a precise reciprocating translation of the second support 5 along the length of the receiving plate 25 through the sliding pair, enabling the brush 6 to achieve full lateral coverage sweeping while rotating and cleaning. The eccentric disc 42-slide groove 431 linkage mechanism simplifies the complex motion trajectory into a single power input through mechanical characteristics, achieving precise synchronous control of the bidirectional movement of the brush 6 within a limited space.

[0054] Further, referring to Figure 4, a roller 44 is rotatably connected to the lever 422. The roller 44 is embedded in the groove 431, and the roller 44 forms rolling friction with the inner wall of the groove 431, significantly reducing the motion resistance between the lever 422 and the groove 431. As the eccentric disk 42 continues to rotate, the roller 44 rolls smoothly in the vertical direction within the groove 431, driving the second bracket 5 to complete a high-frequency reciprocating translational motion.

[0055] In a preferred embodiment, referring to Figures 6 and 7, the system further includes several first height-adjusting feet 20. The first support 3 has several U-shaped notches 31, preferably four, with two U-shaped notches 31 located at one end of the first support 3. By providing four first height-adjusting feet 20, the first support 3 provides stable support. Each first height-adjusting foot 20 includes a foot cup 201 located within the U-shaped notch 31 and two height-adjusting nuts 202 screwed to the foot cup 201. The U-shaped notch 31 is located between the two height-adjusting nuts 202. When it is necessary to adjust the contact pressure between the brush 6 and the receiving plate 25, the operator rotates the two height-adjusting nuts 202 to change the vertical position of the foot cup 201 within the U-shaped notch 31, thereby precisely adjusting the overall installation height of the first support 3 and ensuring that the stainless steel wire bundle of the brush 6 contacts the surface of the receiving plate 25 located in the straight section below the conveying mechanism 2.

[0056] Furthermore, referring to Figures 6 and 7, the system also includes several casters 30 located at the bottom of the first bracket 3. The installation height of the casters 30 is higher than the installation height of the first height adjustment foot 20. Specifically, the bottom of the first bracket 3 is provided with several upwardly extending mounting seats 32, and each caster 30 is installed in a corresponding mounting seat 32 to raise the installation height of the caster 30. When it is necessary to move the cleaning structure, the height adjustment nut 202 is loosened and the first height adjustment foot 20 is removed. At this time, the casters 30 on the first bracket 3 come into contact with the ground, and the omnidirectional rolling characteristic of the casters 30 enables the cleaning structure to be quickly moved or removed as a whole.

[0057] In practical use, 2-3 cleaning structures can be placed below the conveying mechanism 2 along the conveying direction of the short material to ensure the cleaning effect of the receiving plate 25.

[0058] In the above embodiments, as shown in Figures 1 and 2, the frame 1 is provided with a plurality of second height-adjusting feet 11, wherein the structure of the second height-adjusting feet 11 is similar to that of the first height-adjusting feet 20, and the specific structure and working principle can be referred to the first height-adjusting feet 20. The installation height of the conveying mechanism 2 can be adjusted by means of the second height-adjusting feet 11.

[0059] In addition, the gap between two adjacent second height adjustment feet 11 provides an unobstructed passage for the horizontal pulling and placing of the chip collection disc 8, so that no other parts need to be disassembled during cleaning operations.

[0060] In summary, this utility model uses a conveying mechanism 2 to drive multiple receiving plates 25 in a cyclical motion. When the plate reaches the upper straight section, it receives and conveys short materials forward. When it reaches the lower straight section, the brush 6 contacts the surface of the receiving plate 25. Simultaneously, the rotating mechanism 7 drives the brush 6 to rotate, and the translation mechanism 4 drives the brush 6 to reciprocate, thus fully covering and scraping the surface of the receiving plate 25 to remove debris adhering to the surface. This achieves the self-cleaning function of the receiving plate 25, avoiding downtime for maintenance. The design of the first height-adjusting foot 20 and casters 30 enables the adjustment of the installation height of the brush 6 and the rapid position adjustment of the cleaning structure, enhancing the flexibility of the equipment.
