Description

Technical Field

[0001] This invention specifically relates to a square tube fixed-length cutting device for processing luggage handles, and pertains to the field of cutting equipment. Background Technology

[0002] The square tube length-cutting equipment for luggage trolley rod processing is a special processing equipment for the production of luggage trolley rods. It is designed for the automatic length-cutting and precise cutting of thin-walled metal square tube raw materials. It consists of four main structures: base, support mechanism, material transfer mechanism and sawing mechanism. It is suitable for the standardized batch cutting processing of square tubes for luggage trolley rods. A cutting device, disclosed in CN110625177B, includes a base, a cutting assembly, a clamping assembly, and a dust cover. The clamping assembly comprises a first clamping assembly and a second clamping assembly, which are arranged opposite to each other. The first clamping assembly includes a first rotating device, a first clamp disposed on the first rotating device, a first pull rod for controlling the horizontal movement of the first rotating device, and a controller for controlling the rotation of the first rotating device. One end of the first pull rod is connected to the first rotating device, and the other end extends outward through a first side of the dust cover. The controller is disposed on the first side. Using this cutting device facilitates product rotation during the cutting process, allows for changing the cutting surface, meets the needs of different cutting angles and directions, reduces the number of installation and positioning operations, and improves product processing accuracy. In existing equipment, conventional sawing mechanisms have insufficient cutting stability. When the sawing disc rotates at high speed, it is prone to radial oscillation, resulting in poor cut flatness. Furthermore, traditional equipment simply presses the material during cutting, and the material is prone to bouncing and the tool is prone to deviation during high-speed cutting. Summary of the Invention

[0003] To address the aforementioned problems, a technical solution is proposed: a square tube fixed-length cutting device for processing luggage trolley rods, comprising: A base, a support mechanism is installed on the top of the base, a material conveying mechanism is installed on the top of the support mechanism, and a sawing mechanism is installed on the outside of the support mechanism. The sawing mechanism includes a connecting plate, a support plate fixedly mounted on the outer side of the connecting plate, an extension plate fixedly mounted on the top of the support plate, a slide rail on the top of the extension plate, and a sliding table slidably mounted on the slide rail of the extension plate. A cross-cut groove is formed on the top of the extension plate, a second motor is fixedly mounted on the top of the sliding table, and a sawing disc is fixedly mounted on the output end of the second motor. The sawing disc is located at the cross-cut groove of the extension plate, and a pressure plate is fixedly mounted at the cross-cut groove of the extension plate. The bottom of the pressure plate has a central convex shape. The pressure plate has an arc-shaped surface, and a top blade plate is fixedly installed at the center of the side of the pressure plate near the sawing disc. The pressure plate and the top blade plate cooperate with each other, and the arc-shaped surface at the bottom center of the pressure plate is tightly attached to the square tube. During cutting, the material is firmly pressed and prevented from bouncing and shifting during high-speed cutting. The top blade plate is attached to the sawing disc through evenly distributed arc-shaped convex strips, which can limit the high-speed rotating sawing disc, suppress the sawing disc from swinging and shifting, and prevent the cutting edge from being crooked. The top blade plate has evenly distributed arc-shaped convex strips on the side of the top blade plate near the sawing disc, and the top blade plate contacts the outer side of the sawing disc through the arc-shaped convex strips.

[0004] Preferably, the bottom of the support plate is provided with a sliding groove, and a baffle plate is slidably installed at the sliding groove of the support plate. A cylinder is fixedly installed on the top of the raising plate. The cylinder is symmetrically installed at the center position of the axis of the raising plate, and the output end of the cylinder is fixedly connected to both sides of the sliding table.

[0005] Preferably, the support mechanism includes a support platform, the inner wall of which is uniformly provided with rectangular grooves, and an inner rotating column is rotatably installed at each of the rectangular grooves of the support platform. The inner rotating column is higher than the bottom of the inner wall of the support platform. An inner protruding strip is fixedly installed at the bottom of the inner wall of the support platform. A full-range limiting structure is formed by the side baffle and the limiting plate in conjunction with the elastic inner pad column and the inner top plate. The elastic inner pad column provides buffering and shock absorption to avoid rigid compression damage to the thin-walled square tube. The arc-shaped fitting structure of the inner top plate can reduce the contact area and solve the problem of easy scratching when cutting the thin-walled tie rod square tube. The top of the inner protruding strip is lower than the top of the inner rotating column, and a fixing plate is fixedly installed at the center of the inner wall of the support platform. Inner top rods are fixedly installed on both sides of the fixing plate. Side baffles are fixedly installed on both sides of the inner wall of the support platform. The side baffles are located on both sides of the fixing plate, and outer frame plates are fixedly installed on the non-opposing sides of the side baffles.

[0006] Preferably, an inner sliding rod is slidably installed on the inner wall of the side baffle, and an inner pad column is fixedly installed on the outer side of the inner sliding rod. The inner pad column is made of elastic material. One end of the inner sliding rod passes through the outer frame plate and extends to the other side. The end of the inner pad column near the outer frame plate is in contact with the inner wall of the outer frame plate. By arranging rotatable inner rotating columns inside the support platform, the frictional resistance during the square tube feeding process is greatly reduced, ensuring smooth feeding without jamming. The square tube is automatically centered and aligned by the inner top rods on both sides of the fixed plate, ensuring the coaxiality of the cutting from the source. The opposite surfaces of the side baffle are provided with slots, and limit plates are fixedly installed at the slots of the side baffle. An inner top plate is fixedly installed at the other end of the inner sliding rod. The inner top plate is located above the limit plate, and the side of the inner top plate away from the side baffle is evenly arranged on the arc strip.

[0007] Preferably, the material conveying mechanism includes a grooved plate, which is fixedly installed on the top of the support platform. The top of the grooved plate has symmetrical grooves. A first motor is fixedly installed on the top of the grooved plate, and a conveyor roller is fixedly installed at the output end of the first motor. End roller frames are fixedly installed on both sides of the top of the grooved plate, and guide rollers are rotatably installed between the end roller frames. Through the cooperation of the guide rollers and the bottom guide rollers, the conveyor belt is tensioned and limited in both directions to prevent the conveyor belt from deviating and loosening. An adaptive pressing structure is formed by the elastic inner pad and the pressure roller, which can automatically adjust the pressing force according to the thickness of the square tube to ensure that the conveyor belt fits tightly with the square tube and prevents the material from slipping. The conveyor belt is driven between the guide rollers, and the bottom of the conveyor belt contacts the top of the cut square tube material.

[0008] Preferably, a pressure roller is slidably installed on the inner wall of the end roller frame, the bottom of the pressure roller is in contact with the top of the conveyor belt, an inner pad strip is snapped into the inner wall of the end roller frame, the inner pad strip is made of elastic material, and the bottom of the inner pad strip is in contact with both ends of the pressure roller, a fixing block is fixedly installed at the bottom of the end roller frame, a bottom guide roller is rotatably installed between the fixing blocks, the bottom guide roller is located obliquely below the guide roller, and the bottom of the bottom guide roller is in contact with the inner wall of the conveyor belt.

[0009] This invention provides a square tube fixed-length cutting device for processing luggage trolley rods, which has the following beneficial effects: (i) By cooperating with the pressure plate and the top blade plate, the raised arc surface at the bottom center of the pressure plate is closely attached to the square tube, firmly pressing the material during cutting to prevent the material from bouncing and shifting during high-speed cutting. The top blade plate is attached to the sawing disc through evenly distributed arc convex strips, which can limit the high-speed rotating sawing disc, suppress the sawing disc from swinging and shifting, and prevent the cutting cut from being crooked.

[0010] (ii) The side baffle and the limiting plate, together with the elastic inner pad column and the inner top plate, form an all-round limiting structure. The elastic inner pad column provides buffering and shock absorption to avoid rigid compression damage to the thin-walled square tube. The arc-shaped fitting structure of the inner top plate can reduce the contact area and solve the problem of easy scratching when cutting the thin-walled tie rod square tube.

[0011] (III) By arranging rotatable inner rotating columns inside the support platform, the frictional resistance during the feeding process of square tubes is greatly reduced, ensuring smooth feeding without jamming. The square tubes are automatically centered and aligned by the inner top rods on both sides of the fixed plate, ensuring the coaxiality of the cutting from the source.

[0012] (iv) By cooperating with the guide roller and the bottom guide roller, the conveyor belt is tensioned and limited in both directions to prevent the conveyor belt from running off track and loosening. An adaptive pressing structure is formed by the elastic inner pad and the pressure roller, which can automatically adjust the pressing force according to the thickness of the square tube to ensure that the conveyor belt fits tightly with the square tube and prevents the material from slipping.

Detailed Implementation

[0015] Example 1, Reference Figures 1 to 2 and Figures 7 to 8 The present invention provides this technical solution: A fixed-length cutting device for square tubes used in bag and luggage handle processing includes: The base 1 has a support mechanism 2 installed on its top, a material conveying mechanism 3 installed on its top, and a sawing mechanism 4 installed on the outside of the support mechanism 2. The sawing mechanism 4 includes a connecting plate 41, a support plate 43 fixedly mounted on the outer side of the connecting plate 41, a lifting plate 42 fixedly mounted on the top of the support plate 43, a slide rail on the top of the lifting plate 42, and a sliding table 45 slidably mounted on the slide rail of the lifting plate 42. A cross-cutting groove is formed on the top of the lifting plate 42, and a second motor 46 is fixedly mounted on the top of the sliding table 45. According to the required cutting length of the square tube, the position of the baffle plate 44 in the bottom groove of the support plate 43 is adjusted in advance. The baffle plate 44 serves as a limiting reference. When the front end of the square tube is pushed to… When the baffle plate 44 is in contact with the material feeder, the material feeding mechanism 3 stops feeding, completing the fixed-length positioning of the square tube. The connecting plate 41 serves as the overall fixed base for the sawing mechanism 4. The lifting plate 42 on top of the support plate 43 forms the cutting platform. The cylinder 47 is activated. The cylinders 47 are symmetrically installed on both sides of the axis of the lifting plate 42. The output end of the cylinder 47 pushes the sliding table 45 to slide horizontally along the top slide rail of the lifting plate 42, driving the second motor 46 and the sawing disc 48 to move to the cutting position. At the same time, the second motor 46 is activated. The output end of the second motor 46 drives the sawing disc 48 to rotate at high speed. For cutting, a sawing disc 48 is fixedly installed at the output end of the second motor 46. The sawing disc 48 is located at the cross groove of the extension plate 42. A pressure plate 49 is fixedly installed at the cross groove of the extension plate 42. The bottom of the pressure plate 49 is a centrally raised arc surface. A top blade plate 410 is fixedly installed at the center of the side of the pressure plate 49 near the sawing disc 48. Arc-shaped convex strips are evenly arranged on the side of the top blade plate 410 near the sawing disc 48. The pressure plate 49 at the cross groove of the extension plate 42 presses down to fit against the top of the square tube. The centrally raised arc surface at the bottom of the pressure plate 49 can tightly... The material is tightly fitted to the wall of the square tube, achieving pre-cutting clamping and fixation to prevent the square tube from jumping up and down during the cutting process. At the same time, the top blade plate 410 on the inner side of the pressure plate 49 fits against the outer side of the sawing disc 48 through the uniform arc-shaped convex strips on the side wall, which dampens the high-speed rotating sawing disc 48 and guides it to prevent it from swinging and causing the cut to be skewed. The sliding table 45 continues to advance, allowing the high-speed rotating sawing disc 48 to feed along the horizontal blade groove of the heightening plate 42, pass through the wall of the square tube to complete the fixed-length cutting operation, and the top blade plate 410 contacts the outer side of the sawing disc 48 through the arc-shaped convex strips.

[0016] The bottom of the support plate 43 is provided with a sliding groove, and a baffle plate 44 is slidably installed at the sliding groove of the support plate 43. A cylinder 47 is fixedly installed on the top of the lifting plate 42. The cylinder 47 is symmetrically installed at the center position of the axis of the lifting plate 42, and the output end of the cylinder 47 is fixedly connected to both sides of the sliding table 45.

[0017] Example 2, based on Example 1, with reference to Figures 5 to 6 The support mechanism 2 includes a support platform 21. The inner wall of the support platform 21 is evenly provided with rectangular grooves, and inner rotating columns 22 are rotatably installed at each of these grooves. The inner rotating columns 22 are higher than the bottom of the inner wall of the support platform 21. Inner protruding strips 25 are fixedly installed at the bottom of the inner wall of the support platform 21. The square tube of the luggage handle to be cut is manually placed inside the support platform 21. The evenly distributed inner rotating columns 22 protrude from the bottom of the inner wall of the support platform 21, directly supporting the bottom of the square tube. The rotatable inner rotating columns 22 reduce friction during the pushing process of the square tube, ensuring smooth feeding. Simultaneously, the inner protruding strips 25 at the bottom of the inner wall of the support platform 21 assist in supporting the gap at the bottom of the square tube, preventing it from slipping. The tube is suspended and swaying, and the height of the inner protrusion 25 is lower than that of the inner rotating column 22, which does not affect the sliding feeding of the square tube. The inner top rods 24 on both sides of the fixed plate 23 at the center of the support platform 21 extend and retract synchronously to push and calibrate the placed square tube at the center, so that the square tube is kept in the center and the subsequent cutting flatness is guaranteed. The top of the inner protrusion 25 is lower than the top of the inner rotating column 22, and a fixed plate 23 is fixedly installed at the center of the inner wall of the support platform 21. Inner top rods 24 are fixedly installed on both sides of the fixed plate 23. Side baffles 26 are fixedly installed on both sides of the inner wall of the support platform 21. The side baffles 26 are located on both sides of the fixed plate 23, and outer frame plates 27 are fixedly installed on the non-opposing sides of the side baffles 26.

[0018] An inner sliding rod 210 is slidably installed on the inner wall of the side baffle 26, and an inner pad 211 is fixedly installed on the outer side of the inner sliding rod 210. The inner pad 211 is made of elastic material. One end of the inner sliding rod 210 passes through the outer frame plate 27 and extends to the other side. The end of the inner pad 211 near the outer frame plate 27 is in contact with the inner wall of the outer frame plate 27. The opposite surfaces of the side baffles 26 are provided with slots. The side baffles 26 on both sides of the inner wall of the support platform 21 form a lateral limiting barrier. The outer frame plate 27 on the outer side provides fixed support for the overall limiting structure. After the square tube is in place, the inner sliding rod 210 on the inner wall of the side baffle 26 can be adaptively slid and finely adjusted according to the width of the square tube. The elastic inner pad column 211 fixed on the outside fits against the inner wall of the outer frame plate 27, and uses its elasticity to achieve buffering and shock absorption, avoiding collision damage to the square tube during feeding and cutting. The inner top plate 28 at the end of the inner slide rod 210 cooperates with the limiting plate 29 at the slot of the side baffle 26 to form upper and lower limits. The arc structure on the outside of the inner top plate 28 fits against the side wall of the square tube, increasing the contact area and preventing the square tube from shifting left and right. The limiting plate 29 is fixedly installed at the slot of the side baffle 26. The inner top plate 28 is fixedly installed at the other end of the inner slide rod 210. The inner top plate 28 is located above the limiting plate 29, and the side of the inner top plate 28 away from the side baffle 26 is evenly arranged on the arc.

[0019] Example 3, based on Examples 1 and 2, with reference to Figures 3 to 4 The material transfer mechanism 3 includes a grooved plate 31, which is fixedly installed on the top of the support platform 21. The top of the grooved plate 31 has symmetrically arranged grooves. A first motor 32 is fixedly installed on the top of the grooved plate 31. A conveyor roller 35 is fixedly installed at the output end of the first motor 32. The grooved plate 31 is fixed to the top of the support platform 21. Bottom guide rollers 39 between the bottom fixing blocks 310 of the end roller frames 33 support the material transfer belt 34 from the inside. These guide rollers 38, working in conjunction with the guide rollers 38 between the end roller frames 33, complete the overall tensioning and guiding of the material transfer belt 34, ensuring the material transfer belt 34... 4. Once the operation is stable, the first motor 32 is started. The output end of the first motor 32 drives the conveyor roller 35 to rotate. The conveyor roller 35 drives the conveyor belt 34 to circulate. The bottom of the conveyor belt 34 is in close contact with the top of the square tube. Relying on friction, the square tube is pushed forward at a uniform speed along the inner rotating column 22 of the support mechanism 2. End roller frames 33 are fixedly installed on both sides of the top of the grooved plate 31. Guide rollers 38 are rotatably installed between the end roller frames 33. The conveyor belt 34 is installed between the guide rollers 38. The bottom of the conveyor belt 34 is in contact with the top of the cut square tube material.

[0020] A pressure roller 37 is slidably mounted on the inner wall of the end roller frame 33. The bottom of the pressure roller 37 contacts the top of the conveyor belt 34. An inner pad 36 is clamped onto the inner wall of the end roller frame 33. The inner pad 36 is made of elastic material, and its bottom contacts both ends of the pressure roller 37. During feeding, the pressure roller 37 slidably mounted on the inner wall of the end roller frame 33 presses against the top of the conveyor belt 34. Combined with the elastic inner pad 36 clamped onto the inner wall of the end roller frame 33, the elastic pressure of the inner pad 36 presses against the top of the conveyor belt 34. The roller 37 adaptively fits the conveyor belt 34 to ensure that the conveyor belt 34 and the square tube are always tightly fitted to avoid slippage and free rotation. The bottom guide roller 39 is located diagonally below the guide roller 38 and fits the inner wall of the conveyor belt 34 from the inside to achieve fixed-length feeding of the square tube. The bottom of the end roller frame 33 is fixedly installed with fixing blocks 310. The bottom guide roller 39 is rotatably installed between the fixing blocks 310. The bottom guide roller 39 is located diagonally below the guide roller 38, and the bottom of the bottom guide roller 39 fits the inner wall of the conveyor belt 34.

[0021] In support mechanism 2, the square tube of the luggage handle to be cut is manually placed inside support platform 21. Inner rotating columns 22, evenly distributed on the inner wall of support platform 21, protrude from the bottom of the inner wall, directly supporting the bottom of the square tube. The rotatable inner rotating columns 22 reduce friction during the pushing process of the square tube, ensuring smooth feeding. Simultaneously, inner protruding strips 25 at the bottom of the inner wall of support platform 21 assist in supporting the bottom gap of the square tube, preventing it from swaying. Furthermore, the height of the inner protruding strips 25 is lower than the inner rotating columns 22, so it does not affect the sliding feeding of the square tube. The inner push rods 24 on both sides of the fixed plate 23 at the center inside support platform 21 extend and retract synchronously, performing center-pushing calibration on the placed square tube to keep it centered and ensure smooth feeding. To ensure the flatness of the cut, the side baffles 26 on both sides of the inner wall of the support platform 21 form a lateral limiting barrier. The outer frame plate 27 on the outer side provides fixed support for the overall limiting structure. After the square tube is in place, the inner slide rod 210 on the inner wall of the side baffle 26 can be adaptively slid and finely adjusted according to the width of the square tube. The elastic inner pad 211 fixed on the outer side of the inner slide rod 210 fits against the inner wall of the outer frame plate 27, using elasticity to achieve buffering and shock absorption, avoiding collision damage to the square tube during feeding and cutting. The inner top plate 28 at the end of the inner slide rod 210, together with the limiting plate 29 at the slot of the side baffle 26, forms an upper and lower limit. The arc structure on the outer side of the inner top plate 28 fits against the side wall of the square tube, increasing the contact area and preventing the square tube from shifting left and right.

[0022] In the material transfer mechanism 3, the grooved plate 31 is fixed to the top of the support platform 21. The bottom guide rollers 39 between the bottom fixing blocks 310 of the end roller frame 33 support the material transfer belt 34 from the inside. Together with the guide rollers 38 between the end roller frames 33, they complete the overall tensioning and guiding of the material transfer belt 34, ensuring the smooth operation of the material transfer belt 34. Then, the first motor 32 is started. The output end of the first motor 32 drives the conveyor roller 35 to rotate. The conveyor roller 35 drives the material transfer belt 34 to circulate. The bottom of the material transfer belt 34 is in close contact with the top of the square tube, relying on friction. The force drives the square tube to be pushed forward at a constant speed along the inner rotating column 22 of the support mechanism 2. During the feeding process, the pressure roller 37, which is slidably installed on the inner wall of the end roller frame 33, presses on the top of the conveyor belt 34. In conjunction with the elastic inner pad 36 that is snapped into the inner wall of the end roller frame 33, the elastic pressure of the inner pad 36 makes the pressure roller 37 adaptively fit the conveyor belt 34, ensuring that the conveyor belt 34 and the square tube are always tightly fitted, avoiding slippage and free rotation. The bottom guide roller 39 is located obliquely below the guide roller 38 and fits against the inner wall of the conveyor belt 34 from the inside, realizing fixed-length feeding of the square tube.

[0023] In the sawing mechanism 4, the position of the baffle plate 44 in the bottom groove of the support plate 43 is adjusted in advance according to the required cutting length of the square tube. The baffle plate 44 serves as a limiting reference. When the front end of the square tube is pushed to fit the baffle plate 44, the feeding mechanism 3 stops feeding, completing the fixed-length positioning of the square tube. The connecting plate 41 is the overall fixed base of the sawing mechanism 4. The lifting plate 42 on the top of the support plate 43 forms the cutting platform. The cylinder 47 is started. The cylinder 47 is symmetrically installed on both sides of the axis of the lifting plate 42. The output end of the cylinder 47 pushes the sliding table 45 to slide horizontally along the top slide rail of the lifting plate 42, driving the second motor 46 and the sawing disc 48 to move to the cutting position. At the same time, the second motor 46 is started. The output of the second motor 46 drives the sawing disc 48 to rotate at high speed for cutting. The pressure plate 49 at the horizontal groove of the heightening plate 42 presses down and adheres to the top of the square tube. The raised arc surface at the bottom center of the pressure plate 49 can tightly adhere to the wall of the square tube, achieving pre-cutting clamping and fixing, and preventing the square tube from jumping up and down during the cutting process. At the same time, the top blade plate 410 on the inner side of the pressure plate 49 adheres to the outer side of the sawing disc 48 through the uniform arc protrusions on the side wall, which dampens the high-speed rotating sawing disc 48 and guides it to prevent it from swinging and causing the cut to be skewed. The sliding table 45 continues to advance, so that the high-speed rotating sawing disc 48 feeds along the horizontal groove of the heightening plate 42 and passes through the wall of the square tube to complete the fixed-length cutting operation.
