Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to an aluminum profile grinding device. Background Art

[0002] During the processing of aluminum profiles, due to improper design, manufacturing, use and maintenance of the extrusion die, the die surface becomes rough, worn, cracked or deformed, causing friction and adhesion between the extruded aluminum profile and the die, resulting in burrs on the surface of the aluminum profile. Therefore, grinding equipment is needed to remove the burrs, but the current grinding equipment does not clean the aluminum powder after grinding well, causing the aluminum powder to float to the outside, affecting the environment and the health of the workers. Secondly, there is no limit mechanism for aluminum profiles with longer lengths. During the grinding and moving process, the aluminum profile is prone to offset, resulting in deformation of the aluminum profile.

[0003] CN202222041726 discloses a burr grinding device for aluminum profile processing, comprising a workbench, a feed trough, a front conveying roller, a leakage trough, an upper and lower grinding mechanism, a side grinding mechanism and a rear conveying roller, wherein the feed trough is arranged in the middle position of the workbench, and the width of the feed trough is greater than the width of the aluminum profile, the leakage trough is arranged in the middle position of the feed trough, the front conveying roller is installed on both sides of the feed trough at the front end of the leakage trough, the rear conveying roller is installed on both sides of the feed trough at the rear end of the leakage trough, the upper and lower grinding mechanisms are installed at the upper and lower sides of the leakage trough, the side grinding mechanism is installed at the front and rear sides of the leakage trough, and the upper and lower grinding mechanisms are staggered with the side grinding mechanism; the utility model can simultaneously perform deburring and grinding on the upper and lower, front and rear sides of the rectangular aluminum profile surface, and has the advantages of high grinding efficiency, high grinding positioning accuracy, good grinding effect, etc. However, when the grinding device is grinding a long aluminum profile, since there is no limiting mechanism, it can only rely on the upper and lower grinding mechanisms and the side grinding mechanisms to limit the grinding, and the aluminum profile is easy to shake, thereby causing the aluminum profile to deform. Secondly, there is no mechanism for collecting waste.

[0004] The technical problem to be solved by the utility model is: how to radially limit the aluminum profile during the grinding process to prevent the aluminum profile from shifting or shaking to cause poor deformation, and how to collect waste materials. Utility Model Content

[0005] The main purpose of the utility model is to provide an aluminum profile grinding device, which completely fixes the aluminum profile radially through the longitudinal limit unit and the transverse limit unit to prevent the aluminum profile from shaking and avoid defects. Secondly, through the cooperation of the cleaning unit and the collection tank, it is convenient to clean and collect waste.

[0006] To achieve the above objectives, the technical solutions adopted in this application are:

[0007] A grinding device for aluminum profiles comprises a conveying roller unit, a grinding unit, a cleaning unit for cleaning the grinding surface of the profile, a longitudinal limit unit and a transverse limit unit; the grinding unit and the cleaning unit are respectively arranged on the conveying roller unit; a plurality of the longitudinal limit units and the transverse limit units are respectively arranged on both sides of the grinding unit; the longitudinal limit units and the transverse limit units cooperate to form a conveying channel for limiting the radial movement of the profile; a collecting trough for collecting waste is provided at the bottom of the conveying roller unit.

[0008] Compared with the prior art, this solution has the following beneficial effects:

[0009] The aluminum profile grinding device in this case can keep the aluminum profile moving along a straight line when grinding the aluminum profile through the cooperation of multiple longitudinal limit units and transverse limit units to avoid the aluminum profile from bending badly. Then, through the cleaning function of the cleaning unit, the grinding waste (aluminum chips) enters the collection tank. The staff only needs to clean the waste in the collection tank regularly, which reduces the workload of the staff.

[0010] Secondly, the first driving module can simultaneously drive the limit blocks in all the longitudinal limit units to move closer to or away from each other, thereby adjusting the width of the conveying channel so that the width of the entire conveying channel remains uniform, preventing defects caused by collision between the aluminum profile and the limit blocks due to inconsistent width of the conveying channel, and improving the yield rate.

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The components of the present application implemented as described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] Example 1

[0017] refer to Figure 1-4 A grinding device for aluminum profiles comprises a conveying roller unit 1, a grinding unit 2, a cleaning unit 3 for cleaning the grinding surface of the profile, a longitudinal limit unit 4 and a transverse limit unit 5; the grinding unit 2 and the cleaning unit 3 are respectively arranged on the conveying roller unit 1; a plurality of the longitudinal limit units 4 and the transverse limit units 5 are respectively arranged on both sides of the grinding unit 2; the longitudinal limit units 4 and the transverse limit units 5 cooperate to form a conveying channel for limiting the radial movement of the profile; a collecting trough 6 for collecting waste is provided at the bottom of the conveying roller unit 1.

[0018] In this embodiment, among the longitudinal limiting units 4 and the transverse limiting units 5 located on the same side of the grinding unit 2, the transverse limiting unit 5 is arranged between two adjacent longitudinal limiting units 4, thereby forming a conveying channel in which the aluminum profile can only move in a straight line. The cleaning unit 3 is arranged between the grinding unit 2 and the longitudinal limiting unit 4. The conveying roller unit 1 is a conveyor made of conveying rollers in the prior art.

[0019] The grinding unit 2 is the prior art, and the grinding unit 2 includes a lift, a motor and a grinding roller; the grinding roller is installed at the power output end of the motor, the motor is installed on the lift, and the lift is used to adjust the distance between the grinding roller and the conveying roller unit 1.

[0020] In this embodiment, the number of longitudinal limit units 4 on the same side of the grinding unit 2 is 2, and the number of transverse limit units 5 is 1. Different numbers of longitudinal limit units 4 and transverse limit units 5 can also be set according to actual needs. The specific working process of the aluminum profile grinding device is as follows: the staff places the aluminum profile on the conveying roller unit 1, and the conveying roller unit 1 sequentially passes the aluminum profile through the conveying channel formed by the longitudinal limit unit 4, the transverse limit unit 5, and the longitudinal limit unit 4, and then enters the grinding unit 2 for grinding. After the grinding is completed, the cleaning unit 3 cleans the grinding surface of the aluminum profile, and the cleaned waste falls into the collection tank 6. The conveying roller unit 1 then sequentially passes the aluminum profile through the conveying channel formed by the longitudinal limit unit 4, the transverse limit unit 5, and the longitudinal limit unit 4, so that the aluminum profile keeps moving in a straight line during the entire conveying process.

[0021] It should be noted that by providing a longitudinal limit unit 4 and a transverse limit unit 5 on both sides of the grinding unit 2, the two ends of a longer aluminum profile can be fixed, so that the aluminum profile can maintain a straight line movement during the entire conveying process, avoiding deformation of the aluminum profile.

[0022] Secondly, the collecting tank 6 is arranged below the cleaning unit 3 and the grinding unit 2, which can collect the waste materials during grinding and cleaning, prevent the waste materials from polluting the environment, and also reduce part of the cleaning work of the staff.

[0023] Preferably, the lateral limiting unit 5 includes a first fixed frame 51, two limiting blocks 52, and a first driving module 53 for driving the two limiting blocks 52 to move closer to or away from each other; the first fixed frame 51 is arranged on the conveying roller unit 1; the limiting blocks 52 are slidably connected to the first fixed frame 51; and the first driving module 53 is arranged on the first fixed frame 51.

[0024] In this embodiment, the first driving module 53 that moves the two limit blocks 52 closer to or farther away from each other can be implemented by: a motor drives the connecting rod to move, a pneumatic clamp, a screw with left and right threads at both ends respectively, and a threaded connection with the limit block 52, or a double-headed screw 531 and a threaded connection with the limit block 52.

[0025] The first fixing frame 51 is provided with a strip groove; the two limit blocks 52 are slidably connected to the first fixing frame 51 through the strip groove, and the staff adjusts the distance between the two limit blocks 52 through the first driving module 53.

[0026] Preferably, the first driving module 53 includes a double-headed screw 531 and a handwheel 532; the two limit blocks 52 are respectively connected to the two sides of the double-headed screw 531; the handwheel 532 is connected to the end of the double-headed screw 531; the double-headed screw 531 is rotatably connected to the first fixing frame 51.

[0027] In this embodiment, the double-headed screw 531 is arranged on the first fixing frame 51, and the two limit blocks 52 are respectively matched with the threads on both sides of the double-headed screw 531. The staff rotates the hand wheel 532, thereby driving the double-headed screw 531 to rotate, and then driving the two limit blocks 52 to move closer to or away from each other, thereby achieving the distance adjustment of the lateral limit unit 5. In this way, the grinding device can grind multiple aluminum profiles at one time, thereby improving efficiency. The double-headed screw 531 is used, and the manufacturing cost is low and maintenance is convenient.

[0028] More preferably, the multiple double-headed screws 531 can be connected by a synchronous toothed belt transmission, and when the staff rotates the hand wheel 532, all the double-headed screws 531 can be driven to rotate at the same time, so as to adjust all the transverse limit units 5 at one time. In this way, the distance between the two limit blocks 52 of all the transverse limit units 5 can be guaranteed to be equal, and the aluminum profiles can be prevented from colliding with the limit blocks 52 due to adjustment errors, thereby preventing the aluminum profiles from being defective.

[0029] The stop block 52 is a roller made of resin. When the aluminum profile passes through the stop block 52, the stop block 52 and the aluminum profile are connected in a rolling manner to avoid contact between the stop block 52 and the aluminum profile and wear of the aluminum profile. When the stop block is a roller, a slider needs to be installed on the roller to achieve threaded connection with the double-headed screw.

[0030] Preferably, the longitudinal limiting unit 4 includes a second fixed frame 41, a lifting rod 42, a rotating shaft 43, and a second driving module 44 for driving the rotating shaft 43 to move up and down; the second fixed frame 41 is arranged on the conveying roller unit 1; the lifting rod 42 is slidably connected to the second fixed frame 41; the rotating shaft 43 is arranged at the bottom of the lifting rod 42; an elastic member 45 is provided between the rotating shaft 43 and the lifting rod 42; the power output end of the second driving module 44 is connected to the lifting rod 42; the second driving module 44 is arranged on the second fixed frame 41.

[0031] In this embodiment, the second driving module 44 is preferably a screw and a hand wheel 532, but it does not exclude the use of a screw motor, a cylinder or a hydraulic cylinder. Bearing seats are provided at both ends of the rotating shaft 43, and the bearing seats are connected to the lifting rod 42 through studs. The elastic member 45 is provided on the studs, and the elastic member 45 is a spring.

[0032] The specific working process of the longitudinal limit unit 4 is as follows: the staff drives the second drive module 44, and the second drive module 44 drives the lifting rod 42 to move up and down, thereby driving the rotating shaft 43 to move up and down to adjust the height of the conveying channel. When the aluminum profile passes through the longitudinal limit unit 4, the aluminum profile contacts the rotating shaft 43, and the rotating shaft 43 rotates with the movement of the aluminum profile to avoid abrasion of the surface of the aluminum profile. The elastic member 45 keeps the rotating shaft 43 in contact with the aluminum profile through the elastic force, preventing the aluminum profile from shaking in the vertical direction during the grinding process.

[0033] Preferably, a guide shaft 46 is provided between the second fixing frame 41 and the lifting rod 42 ; the guide shaft 46 is slidably connected to the second fixing frame 41 ; and an end of the guide shaft 46 is connected to the lifting rod 42 .

[0034] The guide shaft 46 is provided to prevent the lifting rod 42 from rotating during the up and down movement.

[0035] Preferably, the cleaning unit 3 includes a third fixing frame 31 and a brush 32 ; the third fixing frame 31 is disposed on the conveying roller unit 1 ; the brush 32 is provided with a connecting shaft 33 ; and the connecting shaft 33 is connected to the third fixing frame 31 .

[0036] In this embodiment, the brush 32 is fixed to the third fixing frame 31 by a connecting rod. When the aluminum profile is polished, the surface of the aluminum profile passes through the bristles of the brush 32, thereby removing the waste on the surface of the aluminum profile and allowing the waste to enter the collection tank 6.

[0037] Preferably, the brush 32 is a disc brush or a strip brush.

[0038] In this embodiment, the brush 32 is preferably a disc brush, which is rotatably connected to the connecting shaft 33. When the aluminum profile contacts the disc brush, it will drive the disc brush to rotate, so that the disc brush can sweep out the waste on the surface of the aluminum profile, and the cleaning effect is better.

[0039] Preferably, the bottom of the collecting tank 6 is a gradually narrowing end 61 ; a discharge port 62 is provided at the end of the gradually narrowing end 61 .

[0040] In this embodiment, the bottom of the collecting trough 6 is a tapered end 61, so that the waste can slide along the edge of the bottom to the discharge port 62. A waste frame or a feeder (such as an auger) can be placed below the discharge port 62 to collect the waste in a centralized manner. A negative pressure device can also be provided on the discharge port 62 to make it easier for the waste to enter the discharge port 62.
