Description

Technical Field

[0001] This utility model relates to the field of steel profile cutting technology, and in particular to a material conveying device and a steel profile sawing system for steel profiles. Background Technology

[0002] During the production of steel profiles, they are usually cut according to different needs to meet construction requirements.

[0003] Typically, after cutting, steel profiles are transferred using a hoisting system. Specifically, after each cutting operation, an operator needs to control the hoisting system to perform the following: horizontal movement to position the hoisting tool above the steel profile; vertical movement to bring the hoisting tool closer to the steel profile; manual connection between the hoisting tool and the steel profile; vertical movement to move the hoisting tool upwards; horizontal movement to move the hoisting tool to the preset position; vertical movement to move the hoisting tool downwards to the preset position; and manual separation of the hoisting tool from the steel profile.

[0004] However, the above method has the following drawbacks:

[0005] 1) The operation is cumbersome, requiring manual hoisting and transfer of each steel profile, which is inefficient;

[0006] 2) Applying the same transfer steps to steel profiles of any specification makes it impossible to effectively classify the steel profiles.

[0007] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the inability to effectively classify steel profiles of different specifications, the low efficiency caused by hoisting to transfer all specifications of steel profiles, and the high intensity of manual labor.

[0170] Specifically, the sixth support element 191 is disposed on the side of the plurality of fifth support elements 171 away from the fourth support element 161 and is parallel to the fourth support element 161.

[0171] The extension direction of the sixth support element 191 is the same as that of the fourth support element 161.

[0185] In some embodiments, the second longitudinal drive element includes, but is not limited to, a motor. The second longitudinal drive element is a conventional structure in the art and will not be described in detail here.

[0186] Furthermore, the second discharge longitudinal conveying unit 190 also includes a third tensioning element. This third tensioning element is connected to the fourth longitudinal transmission element and is used to adjust the tension of the fourth longitudinal transmission element.

[0187] In some of these embodiments, the third tensioning element includes, but is not limited to, a tensioning wheel.

[0188] The usage method of this embodiment is as follows:

[0189] (a) Steel profiles of the first specification

[0190] According to the width of the steel profile, the clamping drive element works to drive the second clamping element 132 to move, so that the clamping space between the second clamping element 132 and the first clamping element 131 matches the width of the steel profile.

[0191] After the steel profile is clamped by the second clamping element 132 and the first clamping element 131, the first longitudinal driving element works and drives the clamping unit 130 to move to the preset position (i.e. the position of the transverse pushing unit 150) through the second longitudinal sliding element 143. Several auxiliary conveying elements 112 assist in conveying the steel profile.

[0192] When the clamping unit 130 reaches the preset position, the first longitudinal driving element stops working, and the clamping driving element works to drive the second clamping element 132 to move, thereby releasing the steel profile by the first clamping element 131 and the second clamping element 132; the clamping driving element stops working, and the first longitudinal driving element works to drive the clamping unit 130 to move to the initial position through the second longitudinal sliding element 143.

[0193] The first lateral driving element operates, driving the lateral pushing element to move through the second lateral sliding element. The lateral pushing element abuts against the side of the steel profile and pushes the steel profile to the temporary storage unit 120.

[0194] When the steel profile is located in the temporary storage unit 120, the first lateral drive element works, and drives the lateral push element to move to the initial position through the second lateral sliding element.

[0195] Repeat the above steps until all the steel profiles of the first specification have been transferred.

[0196] When the number of steel profiles in temporary storage unit 120 reaches a threshold, the hoisting system will transfer the steel profiles located in temporary storage unit 120 to the subsequent process.

[0197] (ii) Steel profiles of the second specification

[0198] According to the width of the steel profile, the clamping drive element works to drive the second clamping element 132 to move, so that the clamping space between the second clamping element 132 and the first clamping element 131 matches the width of the steel profile.

[0199] After the steel profile is clamped by the second clamping element 132 and the first clamping element 131, the first longitudinal driving element works and drives the clamping unit 130 to move to a preset position (generally the end of the first longitudinal sliding element 142) through the second longitudinal sliding element 143. Several auxiliary conveying elements 112 assist in conveying the steel profile.

[0200] When the clamping unit 130 reaches the preset position, at least a portion of the steel profile is located in the fourth support element 161. The second longitudinal drive element works, driving a number of first longitudinal transmission elements 163 to rotate through the second longitudinal transmission element, thereby driving a number of first discharge longitudinal conveying elements 162 to rotate, thus driving the steel profile to continue moving longitudinally.

[0201] When the steel profile moves to the preset position, the second longitudinal drive element stops working, and several discharge lifting elements 182 are activated to drive several discharge receiving elements 181 to move upward and abut against the steel profile, thereby driving the steel profile upward away from the fourth support element 161.

[0202] When the steel profile is far away from the fourth support element 161, the second lateral drive element works, and through the cooperation of the first lateral transmission element 172, the second lateral transmission element 173, the third lateral transmission element, and the fourth lateral transmission element 183, it drives the discharge lifting unit 180 to move from the first end of the fifth support element 171 to the second end of the fifth support element 171.

[0203] When the discharge lifting unit 180 reaches the preset position, the second horizontal drive element stops working, and a number of discharge lifting elements 182 move to drive a number of discharge receiving elements 181 to move downward, thereby driving the steel profile downward to approach the fifth support element 171 and place it on the sixth support element 191.

[0204] When the steel profile is located at the sixth support element 191, several discharge lifting elements 182 stop working, and the second transverse drive element works to drive the discharge lifting unit 180 to move to the initial position.

[0205] The third longitudinal drive element works, and through the fourth longitudinal transmission element, it drives several third longitudinal transmission elements 193 to rotate, which in turn drives several second discharge longitudinal conveying elements 192 to rotate, thereby driving the steel profile to continue moving longitudinally to the subsequent process.

[0206] Repeat the above steps until all the steel profiles of the second specification have been transferred.

[0207] The technical effects of this embodiment are as follows: It classifies and transfers steel profiles of different specifications. The transfer of shorter steel profiles is achieved through the cooperation of the lateral pushing unit and the temporary storage unit. The transfer of longer steel profiles is achieved through the cooperation of the first discharge longitudinal conveying unit, the discharge lateral conveying unit, and the second discharge longitudinal conveying unit. This solves the problems of low efficiency and high workload caused by the traditional use of hoisting systems to transfer all types of steel profiles in production. Furthermore, the transfer of steel profiles between the first and second discharge longitudinal conveying units is achieved through the cooperation of the discharge lateral conveying unit and the discharge lifting unit. The first discharge longitudinal conveying unit can continue to transport steel profiles while the discharge lifting unit is transferring them, thereby improving the transfer efficiency.

[0286] The usage method of this embodiment is as follows:

[0287] (a) Conveying steel profiles to be sawed

[0288] When the steel profile is located at the eighth support element 321, several feeding lifting elements 332 are activated to drive several feeding receiving elements 331 to move upward and abut against the steel profile, thereby driving the steel profile upward away from the eighth support element 321.

[0289] When the steel profile is far away from the eighth support element 321, several third transverse drive elements work, and through the cooperation of the fifth transverse transmission element 322, the sixth transverse transmission element 323, the seventh transverse transmission element, and the eighth transverse transmission element 333, drive the feeding lifting unit 330 to move from the first end of the eighth support element 321 to the second end of the eighth support element 321.

[0290] When the feeding lifting unit 330 reaches the preset position, several third transverse driving elements stop working, and several feeding lifting elements 332 move to drive several feeding receiving elements 331 to move downward, thereby driving the steel profile downward to approach the eighth support element 321 and place it on the seventh support element 311.

[0291] The fourth longitudinal drive element works, driving several fifth longitudinal drive elements 313 to rotate through the sixth longitudinal transmission element, thereby driving the steel profile to move longitudinally toward the cutting device 200;

[0292] At this time, the fifth longitudinal drive element can be activated as needed, and the fourth longitudinal sliding element 353 drives the longitudinal pushing unit 340 to push the steel profile.

[0293] (ii) Sawing steel profiles

[0294] According to the preset parameters, the cutting device 200 cuts the steel profile.

[0295] (III) Transfer of steel profiles

[0296] This step is basically the same as steps (i) and (ii) in Example 1, and will not be repeated here.

[0297] The technical effects of this embodiment are as follows: the lateral transfer of steel profiles is achieved by cooperating with the lateral feeding conveying unit and the feeding lifting unit. During the transfer of steel profiles by the feeding lifting unit, the longitudinal feeding conveying unit can continue to transport steel profiles, thereby improving the transfer and conveying efficiency. The lateral feeding is achieved by cooperating with the lateral feeding conveying unit and the longitudinal feeding conveying unit, which greatly reduces the length of the longitudinal feeding conveying unit and thus reduces the floor space occupied.

Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
