Description

Technical Field

[0001] The present application relates to the technical field of packaging boxes, and in particular to a steel grating processing and cutting device. Background Art

[0002] The steel grating is an open steel structure that is made of load-bearing flat steel and cross bars that are orthogonally combined at a certain distance and fixed by welding or compression locking. When in use, the steel grating can be cut according to actual needs.

[0003] For related technologies, reference may be made to Chinese patent publication number CN217666830U, which discloses a cutting saw for convenient loading and unloading of steel gratings, including a feed roller seat unit and a grating pressing and cutting unit installed on the feed roller seat unit, wherein the feed shaft roller is installed on the side of the cross bar of the support rod frame through a reinforced bearing plate, so that it is convenient to feed the steel grating during loading and unloading, and at the same time, the wear on the steel grating is reduced; the cutting saw is installed on the screw slider assembly, and the screw slider assembly is arranged on the pressure frame, so that when cutting, the hydraulic cylinder drives the pressure frame to press down the steel grating, and the cutting saw cuts the steel grating at the same time, and the pressure frame can press and fix the two sides of the cutting opening of the steel grating well to ensure smooth cutting.

[0004] When the saw blade cuts the steel grating, both the saw blade and the steel grating are made of metal, and the heat generated by the friction between the two is relatively high. Currently, the heat dissipation method of the saw blade cutting the steel grating is usually natural cooling, which takes a long time to dissipate heat. However, the production and processing of steel gratings generally require long-term continuous work, that is, the saw blade needs to perform intermittent cutting work for a long time. The heat dissipation time of the saw blade is short, and the heat dissipation effect is long, which affects the service life of the saw blade. Summary of the invention

[0005] In order to increase the service life of saw blades, the present application provides a steel grating processing and cutting equipment.

[0006] The present application provides a steel grating processing and cutting device that adopts the following technical solution:

[0007] A steel grating processing and cutting equipment comprises a conveying table and a cutting table, wherein the conveying table comprises a plurality of conveying rollers, the length direction of the cutting table is consistent with the length direction of the conveying rollers, the cutting table is slidably connected with a cutting seat located below the conveying rollers, the cutting seat is rotatably connected with a cutting frame, the cutting frame is provided with two cutting stations arranged one above and one below, both cutting stations are rotatably connected with saw blades, the cutting seat is provided with a cooling air outlet directly opposite to the lower cutting station, a cooling fan is provided in the cooling air outlet, and the upper end of the upper saw blade protrudes beyond the conveying rollers.

[0008] By adopting the above technical solution, the steel grating is transported to the cutting table on the conveying table, and the cutting seat moves from the head end to the end of the cutting table. During the movement, the saw blade above the cutting seat starts to cut the steel grating. After the cutting is completed, the steel grating continues to be transported forward to prepare for the next cutting. At this time, the cutting frame rotates, so that the two cutting stations are exchanged. The saw blade that has just finished cutting is located at the bottom and has a higher temperature. The cooling fan blows air to cool the saw blade to cool it. The saw blade on the other station has a lower temperature and is ready for cutting. The cutting seat moves from the end to the head end along the cutting table, and the saw blade below is always air-cooled. After the temperature drops, the cutting frame flips again to prepare for the next cutting work, and the cycle repeats. Through the setting of the cutting frame and two cutting stations, the two saw blades work alternately, and the cooling time of a single saw blade is longer than that of the existing saw blade. The saw blade is air-cooled in the form of a cooling fan, and the cooling efficiency is improved, resulting in a better overall cooling effect of the saw blade, thereby increasing the service life of the saw blade.

[0009] Preferably, a cooling groove for accommodating a saw blade is provided on the surface of the cutting seat, and a plurality of nozzles for spraying cooling liquid are provided in the cooling groove.

[0010] By adopting the above technical solution, when the saw blade located at the bottom is cooled, the cooling fan performs air cooling on the upper end of the saw blade, and the coolant performs liquid cooling on the lower end of the saw blade. The two cooperate with each other to further improve the cooling effect of the saw blade.

[0011] Preferably, the cutting station is rotatably connected to a rotating shaft connected to a saw blade, the cutting frame is provided with a cutting motor for driving the rotating shaft to rotate, the cutting frame is rotatably connected to a cutting shaft at the center, the output shaft of the cutting motor is connected to the cutting shaft, the axes of the cutting shaft and the two rotating shafts are located on the same straight line, the cutting shaft and the two rotating shafts are connected by two transmission rods respectively, one end of the transmission rod is connected to the cutting shaft by a bevel gear pair, and the other end is connected to the rotating shaft by a bevel gear pair.

[0012] By adopting the above technical solution, the cutting motor drives the cutting shaft to rotate, and the cutting shaft drives two transmission rods to rotate through two sets of bevel gear pairs, and the two transmission rods drive two rotating shafts to rotate through the bevel gear pairs, thereby driving the saw blade to rotate. Thus, one cutting motor can drive two saw blades to rotate, reducing the power source, saving power and reducing the overall weight.

[0013] Preferably, the transmission rod comprises an upper tube, a middle rod and a lower tube connected in sequence, the end of the upper tube facing away from the lower tube is connected to the cutting shaft via a bevel gear pair, the end of the lower tube facing away from the upper tube is connected to the rotating shaft via a bevel gear pair, the middle rod is slidably connected between the upper tube and the lower tube, and upper and lower grooves are respectively provided at both ends of the middle rod, a lower block slidably connected to the lower groove is fixed to the inner wall of the lower tube, an upper block slidably connected to the upper groove is fixed to the inner wall of the upper tube, and when the middle rod contacts the bottom of the lower tube, the upper block detaches from the upper groove.

[0014] By adopting the above technical solution, the two rotating shafts are arranged one above and one below, and the directions of the two transmission rods are also opposite. That is, the transmission rod connected to the rotating shaft below is in the order of upper tube, middle rod and lower tube from top to bottom, while the transmission rod connected to the rotating shaft above is in the order of lower tube, middle rod and upper tube from top to bottom. At this time, under the action of its own gravity, the transmission rod connected to the rotating shaft above, the middle rod descends and contacts the bottom of the upper tube, and its lower block is embedded in the lower groove, and the upper block is embedded in the upper groove. The upper tube rotates under the drive of the cutting shaft, and the middle rod and the lower tube rotate synchronously, thereby driving the rotating shaft above to rotate. While the transmission rod connected to the rotating shaft below, under the action of its own weight, the middle rod descends and contacts the bottom of the lower tube, and its lower block is embedded in the lower groove, but the upper block is separated from the upper groove. At this time, the middle rod is separated from the upper tube, and when the upper tube rotates with the cutting shaft, the middle rod and the lower tube do not move, that is, the rotating shaft below does not rotate. The lower saw blade does not perform cutting work, thereby facilitating the cooling work of the lower saw blade and also reducing the load pressure of the cutting motor.

[0015] Preferably, a counterweight is provided at the end of the middle rod.

[0016] By adopting the above technical solution, the counterweight block increases the weight of the middle pole, which facilitates the falling of the middle pole and prevents the middle pole from getting stuck.

[0017] Preferably, the upper blocks are provided in plurality and are evenly fixed to the inner wall of the upper tube in the circumferential direction.

[0018] By adopting the above technical solution, a plurality of upper blocks are provided, which facilitates the upper block to be inserted into the upper groove.

[0024] By adopting the above technical solution, when the cutting seat moves to one end of the cutting table, it means that the cutting is completed. At this time, the touch block contacts the touch switch, and the touch switch triggers and controls the flip motor to start, so that the two stations are exchanged, thereby improving the degree of automation.

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings. Example

[0034] The present application embodiment discloses a steel grating processing and cutting device, referring to Figures 1 to 4 , including a conveying platform 1 and a cutting platform 2, the steel grating is conveyed on the conveying platform 1, and the cutting platform 2 cuts the steel grating.

[0035] Reference Figures 1 to 4 The conveying table 1 includes a plurality of conveying rollers 11 arranged in parallel, with gaps between the conveying rollers 11. The length direction of the cutting table 2 is consistent with the length direction of the conveying rollers 11. The cutting table 2 is located below the conveying rollers 11. A moving lead screw 27 is rotatably connected in the cutting table 2, and a moving motor 28 connected to the moving lead screw 27 is fixed at the end of the cutting table 2. A cutting seat 21 threadedly connected to the moving lead screw 27 is slidably connected in the cutting table 2. When the moving motor 28 is started, the moving lead screw 27 rotates, and the cutting seat 21 moves linearly along the length direction of the cutting table 2.

[0036] Reference Figures 1 to 4 The cutting seat 21 is rotatably connected to a cutting frame 3, and two cutting stations arranged one above and one below are provided on the cutting frame 3. The two cutting stations are rotatably connected to a rotating shaft 31, and a saw blade 4 is installed on the rotating shaft 31. The upper end of the saw blade 4 located above exceeds the conveying roller 11. When cutting, the upper saw blade 4 rotates, and the lower saw blade 4 dissipates heat and waits. The cutting seat 21 moves along the cutting table 2, and the upper saw blade 4 cuts the steel grating. After the cutting is completed, the cutting frame 3 rotates the two cutting stations to exchange, and the lower saw blade 4 is located at the top to prepare for the cutting operation, and the saw blade 4 that has just completed the cutting operation is turned to the bottom to dissipate heat. The two saw blades 4 work alternately, which prolongs the heat dissipation time of the saw blade 4 and ensures the heat dissipation effect of the saw blade 4, thereby protecting the saw blade 4 and increasing its service life.

[0037] Reference Figures 1 to 4 A turning gear 33 is fixed at the center of the cutting frame 3, a turning motor 8 is installed on the cutting seat 21, and a driving gear 81 meshing with the turning gear 33 is coaxially fixed on the output shaft of the turning motor 8. When the turning motor 8 is started, the cutting frame 3 is turned over to realize the exchange of the two cutting stations.

[0038] Reference Figures 1 to 4 , touch switches 25 are respectively provided on both sides of the cutting seat 21, and touch blocks 26 for triggering the touch switches 25 are provided at both ends of the cutting table 2. The touch switches 25 are electrically connected to the flip motor 8 through the controller. When the cutting seat 21 moves to one end of the cutting table 2, it means that the cutting is completed. At this time, the touch block 26 contacts the touch switch 25, and the touch switch 25 triggers and controls the flip motor 8 to start, so that the two stations are exchanged, thereby improving the degree of automation.

[0039] Reference Figures 1 to 4The surface of the cutting seat 21 is provided with a cooling groove 23 for accommodating the saw blade 4. The cooling groove 23 is provided with a plurality of nozzles 24 for spraying coolant. The lower end of the saw blade 4 below is embedded in the cooling groove 23. The cooling nozzles 24 are located on both sides of the saw blade 4 and directly opposite to the saw blade 4. The cutting seat 21 is provided with a cooling air port 22 directly opposite to the cutting station below. The cooling air port 22 is provided with a cooling fan 5. The cooling air port 22 is directly opposite to the upper end of the saw blade 4 below. The cold air blown by the cooling fan 5 cools the upper end of the saw blade 4 below, and the nozzles 24 cool the lower end of the saw blade 4 with coolant. Moreover, the saw blade 4 rotates under the blowing of the cold air, so that the overall cooling of the saw blade 4 can be achieved. The saw blade 4 is cooled by a combination of air cooling and liquid cooling, and the cooling effect is better.

[0040] Reference Figures 1 to 4 The cutting shaft 32 is rotatably connected at the center of the cutting frame 3, and a cutting motor 6 connected to the cutting shaft 32 is fixed on the side of the cutting frame 3 away from the flip gear 33, and the cutting motor 6 drives the cutting shaft 32 to rotate. The cutting shaft 32 and the axis of the two rotating shafts 31 are located on the same straight line, and the cutting shaft 32 and the two rotating shafts 31 are respectively connected through two transmission rods 7, one end of the transmission rod 7 is connected to the cutting shaft 32 through a bevel gear pair, and the other end is connected to the rotating shaft 31 through a bevel gear pair. When the cutting shaft 32 rotates, the two transmission rods 7 rotate synchronously, thereby driving the two rotating shafts 31 to rotate at the same time, that is, one cutting motor 6 can drive the saw blades 4 on the two cutting stations to rotate, saving a power source and reducing the overall weight of the device.

[0041] Reference Figures 1 to 4 Only the saw blade 4 located at the top performs cutting work, and the saw blade 4 located at the bottom performs cooling. Therefore, the saw blade 4 does not need to rotate when it is at the bottom. If the cutting motor 6 always drives the two saw blades 4 to rotate synchronously, it will cause energy waste and will also affect the heat dissipation effect of the saw blade 4 at the bottom.

[0042] Reference Figures 1 to 4 The transmission rod 7 includes an upper tube 71, a middle rod 72 and a lower tube 73 connected in sequence. The end of the upper tube 71 away from the lower tube 73 is connected to the cutting shaft 32 through a bevel gear pair, and the end of the lower tube 73 away from the upper tube 71 is connected to the rotating shaft 31 through a bevel gear pair. The middle rod 72 is slidably connected between the upper tube 71 and the lower tube 73. A counterweight block 74 is fixed to the end of the middle rod 72, and the middle rod 72 can slide between the upper tube 71 and the lower tube 73 under the action of its own gravity. The transmission rod 7 connected to the rotating shaft 31 below is, from top to bottom, the upper tube 71, the middle rod 72 and the lower tube 73. The transmission rod 7 connected to the rotating shaft 31 above is, from top to bottom, the lower tube 73, the middle rod 72 and the upper tube 71. The transmission rod 7 below is in the opposite direction to the transmission rod 7 above.

[0043] Reference Figures 1 to 4 The upper end and the lower end of the middle rod 72 are respectively provided with an upper groove 721 and a lower groove 722, and the inner wall of the lower tube 73 is fixed with a lower block 731 which is slidably connected to the lower groove 722. The length of the lower groove 722 is greater than the movement stroke of the middle rod 72, that is, during the sliding process of the middle rod 72, the lower block 731 always slides in the lower groove 722. That is, when the middle rod 72 contacts the bottom of the upper tube 71 or the middle rod 72 contacts the bottom of the lower tube 73, the lower block 731 is embedded in the lower groove 722.

[0044] Reference Figures 1 to 4 A plurality of upper blocks 711 are fixed to the inner wall of the upper tube 71 in a circumferential direction and are slidably connected to the upper groove 721. The upper blocks 711 are tapered at one end facing the upper groove 721. The length of the upper groove 721 is smaller than the movement stroke of the middle rod 72, and when the middle rod 72 contacts the bottom of the lower tube 73, the upper blocks 711 are separated from the upper groove 721; when the middle rod 72 contacts the bottom of the upper tube 71, the upper blocks 711 are embedded in the upper groove 721.

[0045] That is, the transmission rod 7 located at the bottom, its lower tube 73 is located at the bottom, and the middle rod 72 descends under its own weight and contacts the bottom of the lower tube 73. At this time, the upper block 711 is separated from the upper groove 721, and the middle rod 72 and the upper tube 71 are separated. When the cutting shaft 32 drives the upper tube 71 to rotate, the middle rod 72, the lower tube 73 and the saw blade 4 below do not rotate, thereby facilitating the cooling of the saw blade 4 below and also reducing the load of the cutting motor 6.

[0046] The transmission rod 7 located at the top has its lower tube 73 located at the top and the upper tube 71 located at the bottom. The middle rod 72 descends under its own gravity and contacts the bottom of the upper tube 71. At this time, the upper block 711 is embedded in the upper groove 721, and the lower block 731 is embedded in the lower groove 722. The upper tube 71 and the lower tube 73 are connected through the middle rod 72. When the cutting shaft 32 rotates, the upper tube 71 drives the lower tube 73 to rotate through the middle rod 72, and the lower tube 73 drives the upper rotating shaft 31 and the saw blade 4 to rotate to achieve cutting.

[0047] When the transmission rod 7 located at the bottom is rotated to the top again, the upper block 711 and the upper groove 721 are easily misaligned. Therefore, multiple upper blocks 711 are set on the inner wall of the upper tube 71. Any upper block 711 can be inserted into the upper groove 721 to achieve the connection between the middle rod 72 and the upper tube 71, which is easy to use. Moreover, the end of the upper block 711 facing the upper groove 721 is set to be conical, which also facilitates the insertion of the upper block 711.

[0048] The implementation principle of a steel grating processing and cutting device in an embodiment of the present application is as follows: the steel grating is transported on a conveying table 1 and transported to a cutting table 2 for cutting. The motion motor 28 is started, and the cutting seat 21 moves along the cutting table 2. The cutting motor 6 is started, and the saw blade 4 located above rotates to cut the steel grating until the cutting seat 21 moves to the other end of the cutting table 2, and the cutting is completed. At this time, the touch switch 25 controls the flip motor 8 to start, the cutting frame 3 rotates, and the two saw blades 4 exchange positions. The saw blade 4 that has just completed the cutting is located at the bottom and embedded in the cooling groove 23 for cooling and is not controlled by the cutting motor 6. The saw blade 4 that was previously located at the bottom now turns to the top and is connected to the cutting motor 6, ready for the next cutting.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
