Description

Technical Field

[0001] The present invention relates to the field of double saw belts, and specifically to a tensioning structure for a double saw belt machine and its operation method. Background Technique

[0002] In the metal processing industry, a double saw belt machine is a commonly used cutting device, mainly used for quickly and efficiently cutting metal materials. Existing double saw belt machines usually adopt a manually adjusted tensioning mechanism. Operators need to judge the tension of the saw belt based on experience or visual inspection and make manual adjustments.

[0003] Manual adjustment is difficult to accurately control the tension of the saw belt, and it is easy to cause the saw belt to be too tight or too loose. Being too tight will increase the wear of the saw belt and shorten its service life; being too loose will lead to a decrease in cutting accuracy and even the situation of the saw belt falling off. Moreover, manual adjustment requires frequent intervention by operators, increasing the operation difficulty and workload. Especially during long-term continuous operation, operators are prone to fatigue, affecting the accuracy of adjustment. Summary of the Invention

[0017] Further, a pair of fixing frames are symmetrically arranged below the top end and above the bottom end of the side of the double saw band machine body away from the box body, and a guide roller is movably installed at the end of each of the two fixing frames through a rotating shaft, and the two guide rollers are respectively movably connected to the first metal saw band and the second metal saw band.

[0018] An operation method of a tensioning structure for a double saw band machine includes the following steps:

[0019] The first step: When the driving motor controls the rotation of the first saw wheel and the second saw wheel, the first metal saw band and the second metal saw band movably installed inside the two movable grooves can be driven to roll, and when the first metal saw band and the second metal saw band roll, the materials are quickly cut;

[0020] The second step: When the first metal saw band and the second metal saw band are driven by the first saw wheel and the second saw wheel, the tensioning frame arranged inside the double saw band machine body drives the tensioning wheel to always control the tension of the first metal saw band and the second metal saw band through the spiral spring, and presses the first metal saw band and the second metal saw band against the side of the first saw wheel and the second saw wheel, so that the wrap angle of the first metal saw band and the second metal saw band with the first saw wheel and the second saw wheel can be increased;

In this way, the wrap angle of the metal saw band 1 and the metal saw band 2 and the saw wheel 1 and the saw wheel 2 can be increased, so as to facilitate the control of the tension of the double-saw band and improve the wrap angle;

[0025] 2. When the metal saw band 1 and the metal saw band 2 in the present invention are driven by the saw wheel 1 and the saw wheel 2, the centrifugal fan installed outside one side of the back of the double-saw band machine body starts. After the centrifugal fan starts, the debris remaining on the surfaces of the metal saw band 1 and the metal saw band 2 is sucked into the air duct through the adsorption port, then enters the box body, and is separated by the dense mesh, so as to achieve the purpose of easy cleaning.

[0035] Please refer to Figure 1-7 , the present invention provides a technical solution:

[0036] A tensioning structure for a double saw band machine, including a double saw band machine body 1. An inner groove 2 is opened inside the double saw band machine body 1. A first saw wheel 3 is movably installed at the upper end inside the inner groove 2, and a second saw wheel 4 is movably installed at the bottom end inside the inner groove 2. Movable grooves 5 are respectively opened inwardly on both sides of the first saw wheel 3 and the second saw wheel 4. A first metal saw band 6 and a second metal saw band 7 are respectively movably installed inside the movable grooves 5 on both sides of the first saw wheel 3 and the second saw wheel 4; A cleaning mechanism 8 is arranged outside one side of the back of the double saw band machine body 1. The cleaning mechanism 8 includes a box body 801, a centrifugal fan 802 and a filter cover 803. A conveying mechanism 9 is arranged inside one side of the back of the double saw band machine body 1. The conveying mechanism 9 includes an adsorption port 901, a dust removal plate 902 and an air duct 903; Sleeves 10 are arranged on both sides of the back of the double saw band machine body 1 close to the first saw wheel 3 and the second saw wheel 4. A tensioning mechanism 11 is arranged on one side of the sleeve 10 close to the inner groove 2. The tensioning mechanism 11 includes a helical spring 1101, a tensioning frame 1102 and a tensioning wheel 1103.

[0037] As Figure 1 and Figure 4As shown, a box body 801 is fixedly installed on the outer side of the back of the double saw belt machine body 1. A centrifugal fan 802 is fixedly installed on the outer side of one side of the box body 801. A filter cover 803 is fixedly installed on the outer side of the centrifugal fan 802 away from the box body 801. An adsorption port 901 is fixedly installed at one end of the inner part of the box body 801 close to the inner groove 2. A dust removal plate 902 is fixedly connected to the side of the adsorption port 901 away from the box body 801. An air passage 903 is penetrated and opened between the dust removal plate 902 and the adsorption port 901 and the inside of the box body 801. A dense net 12 is fixedly installed in the middle of the inner side of the box body 801, and the bottom end of the dense net 12 is inclined towards the side of the centrifugal fan 802;

[0038] In this embodiment, when the metal saw belt one 6 and the metal saw belt two 7 are driven by the saw wheel one 3 and the saw wheel two 4, the centrifugal fan 802 installed on the outer side of the back of the double saw belt machine body 1 is started. After the centrifugal fan 802 is started, the debris remaining on the surfaces of the metal saw belt one 6 and the metal saw belt two 7 is sucked into the air passage 903 through the adsorption port 901, then enters the box body 801, and is separated by the dense net 12.

[0039] As Figure 1 and Figure 4 shown, a tripod 13 is fixedly installed at the bottom end of the side of the double saw belt machine body 1 close to the box body 801. A collection box 14 is fixedly installed at the top end of the tripod 13. A bottom groove 15 is penetrated and opened at the bottom end of the box body 801;

[0040] In this embodiment, the debris separated by the dense net 12 will fall to the position of the bottom groove 15, then pass through the bottom groove 15 and enter the collection box 14 at the top end of the tripod 13, while the air is discharged after passing through the centrifugal fan 802 and the filter cover 803.

[0041] As Figure 1 and Figure 5 shown, a spiral spring 1101 is fixedly installed inside the sleeve 10. One end of the spiral spring 1101 close to the inner groove 2 is fixedly connected to a tensioning frame 1102. One end of the tensioning frame 1102 away from the spiral spring 1101 is movably installed with a tensioning wheel 1103 through a rotating shaft;

[0042] In this embodiment, when the metal saw belt one 6 and the metal saw belt two 7 are driven by the saw wheel one 3 and the saw wheel two 4, the tensioning frame 1102 arranged inside the double saw belt machine body 1 drives the tensioning wheel 1103 through the spiral spring 1101 to always control the tension of the metal saw belt one 6 and the metal saw belt two 7, and presses the metal saw belt one 6 and the metal saw belt two 7 towards the side of the saw wheel one 3 and the saw wheel two 4. At the same time, since the tensioning wheel 1103 is arranged on the side close to the saw wheel one 3 and the saw wheel two 4, the wrap angle of the metal saw belt one 6 and the metal saw belt two 7 and the saw wheel one 3 and the saw wheel two 4 can be increased.

[0043] As Figure 5As shown, guide grooves 16 are provided at both the inner top and bottom inner walls of the sleeve 10. Guide blocks 17 are fixedly connected to both the outer top and bottom sides of the tensioning frame 1102 close to the spiral spring 1101. The guide blocks 17 are slidably connected to the guide grooves 16;

[0044] In this embodiment, when the tensioning frame 1102 automatically adjusts the tension of the first metal saw band 6 and the second metal saw band 7, it drives the guide blocks 17 to slide along the inside of the guide grooves 16 for guiding.

[0045] As Figure 6 shown, a pair of shaft brackets 18 are fixedly connected to the inner wall of the side of the double-saw-band machine body 1 away from the suction port 901. Pressing rollers 19 are movably installed at the ends of the two shaft brackets 18 through rotating shafts. The two pressing rollers 19 are respectively movably connected to the first metal saw band 6 and the second metal saw band 7;

[0046] In this embodiment, the pressing rollers 19 are movably installed through the shaft brackets 18 on the inner side of the double-saw-band machine body 1, so as to cooperate with the tensioning wheels 1103 to increase the tension of the first metal saw band 6 and the second metal saw band 7.

[0047] As Figure 7 shown, a pair of fixing brackets 20 are symmetrically arranged respectively below the top and above the bottom on the side of the double-saw-band machine body 1 away from the box body 801. Guide rollers 21 are movably installed at the ends of the two fixing brackets 20 through rotating shafts. The two guide rollers 21 are respectively movably connected to the first metal saw band 6 and the second metal saw band 7;

[0048] In this embodiment, the purpose of setting the fixing brackets 20 and the guide rollers 21 is to avoid bending when the first metal saw band 6 and the second metal saw band 7 cut the material, so that the cross-section of the cut material is flat.

[0049] An operation method of a tensioning structure for a double-saw-band machine includes the following steps:

[0050] The first step: When the driving motor controls the rotation of the first saw wheel 3 and the second saw wheel 4, it can drive the first metal saw band 6 and the second metal saw band 7 movably installed in the two movable grooves 5 to roll, and the first metal saw band 6 and the second metal saw band 7 quickly cut the material when rolling;

[0051] The second step: When the first metal saw band 6 and the second metal saw band 7 are driven by the first saw wheel 3 and the second saw wheel 4, the tensioning frame 1102 arranged on the inner side of the double-saw-band machine body 1 drives the tensioning wheel 1103 through the spiral spring 1101 to always control the tension of the first metal saw band 6 and the second metal saw band 7, and presses the first metal saw band 6 and the second metal saw band 7 against one side of the first saw wheel 3 and the second saw wheel 4, so as to increase the wrap angle of the first metal saw band 6 and the second metal saw band 7 with the first saw wheel 3 and the second saw wheel 4;

[0052] Step 3: When the metal saw band 1 and the metal saw band 2 are driven by the saw wheel 1 and the saw wheel 2, the centrifugal fan 802 installed outside one side of the back of the double-saw band machine body 1 is started. After the centrifugal fan 802 is started, the debris remaining on the surfaces of the metal saw band 1 and the metal saw band 2 is sucked into the air duct 903 through the adsorption port 901, then enters the box body 801, and is separated by the dense net 12;

[0053] Step 4: The debris separated by the dense net 12 will fall to the position of the bottom groove 15, then pass through the bottom groove 15 and enter the collection box 14 at the top of the tripod 13, while the air is discharged after passing through the centrifugal fan 802 and the filter cover 803.
