Description

Technical Field

[0001] The utility model relates to the technical field of band sawing machines, in particular to a loading device for a band sawing machine. Background Art

[0002] A sawing machine is a machine tool that uses saw belts, saw blades and other tools to cut the materials that need to be cut. Among them, a sawing machine that uses saw belts as tools is called a band saw. Band saws are a widely used cutting device, mainly used for cutting longer materials.

[0003] According to the prior art, CN217166783U discloses a feeding device for a band sawing machine, wherein the feeding device is provided with a lifting mechanism, thereby lowering the height of the upper end of the material transporting mechanism, making it convenient for workers to place the bar material on the material transporting mechanism, and starting the lifting mechanism again to raise the height of the upper end of the material transporting mechanism so that the upper end of the material transporting mechanism is consistent with the height of the material storage rack, thereby completing the feeding and improving the work efficiency; starting the driving mechanism, the driving mechanism drives the material transporting mechanism to approach the sawing machine body, thereby transporting the bar material to the material storage rack, reducing the time of manual handling, thereby improving the work efficiency, but the feeding device is not convenient for controlling the feeding length when the material is long, and when different lengths need to be sawed, it still needs to rely on manual measurement, which has low work efficiency, so we propose a feeding device for a band sawing machine Utility Model Content

[0004] The utility model aims to provide a feeding device for a band saw bed, which has the advantages that the feeding length can be adjusted so as to conveniently saw the bar material into different lengths to improve the working efficiency.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a band saw loading device, comprising a frame, a sawing machine body mounted on the frame, a loading rack fitted with the frame, and a transfer assembly mounted on the loading rack, two guide plates being mounted on the loading rack, a supporting assembly that can move up and down being movably mounted between the two guide plates, an extrusion plate being mounted on the supporting assembly, a moving assembly being mounted on the guide plate, a pressure sensor being mounted on the moving assembly, a controller being mounted on the loading rack, and the controller being electrically connected to the pressure sensor and the supporting assembly.

[0006] By adopting the above technical solution, when loading, the supporting assembly moves down and fits with the surface of the transfer assembly, and the transfer assembly starts to drive the supporting assembly to move on the guide plate close to the sawing machine body to complete the loading. When the extrusion plate on the supporting assembly moves to the pressure sensor and squeezes the pressure sensor, the controller controls the supporting assembly to move up and no longer fits with the surface of the transfer assembly. At this time, the loading is no longer continued, thereby limiting the loading length of the bar material. No manual measurement is required, and the work efficiency is high. At the same time, the pressure sensor is installed on the moving assembly, and the position of the fixed point of the pressure sensor can be changed, and the loading length of the bar material can be changed, which has higher applicability.

[0007] The utility model is further configured as follows: the transfer assembly includes a plurality of transfer rollers rotatably connected to the inner side of the loading rack, a belt transmission-connecting two adjacent transfer rollers, and a transfer motor installed on the loading rack to drive one of the transfer rollers to rotate.

[0008] By adopting the above technical solution, the transfer motor starts to drive one of the transfer rollers to rotate. When one of the transfer rollers rotates, the belt drives other transfer rollers to rotate synchronously, so that the rods placed on the supporting assembly can be loaded.

[0009] The utility model is further configured as follows: the material supporting assembly includes a connecting side plate movably connected to the guide plate, a vertical slot provided on the connecting side plate, a rotating motor installed on the connecting side plate, a screw rotatably connected to the inner wall of the vertical slot and connected to the output shaft of the rotating motor, a slider movably connected to the inner wall of the vertical slot and threadedly connected to the outside of the screw, and a supporting plate connected between the two sliders.

[0010] The utility model is further configured as follows: the extrusion plate is mounted on the connecting side plate, and the contact surface between the support plate and the transfer roller is designed to increase resistance.

[0011] By adopting the above technical solution, the bar to be sawed is placed on the pallet, and the motor is started to drive the screw to rotate, so that the slider moves up and down in the vertical groove, thereby driving the pallet to move up and down and fit or separate from the transfer roller. When the pallet fits the transfer roller, the bar is loaded, and when the pallet separates from the transfer roller, the loading is stopped. The resistance-increasing design facilitates better movement of the pallet on the transfer roller.

[0012] The utility model is further configured as follows: the moving assembly includes a track installed on the loading rack, a connecting seat movably installed outside the track, a plurality of screw holes opened on the track, and bolts threadedly connecting the connecting seat and the track through the screw holes.

[0013] The utility model is further configured as follows: a plurality of screw holes are distributed on the track at equal distances.

[0014] The utility model is further configured as follows: the pressure sensor is mounted on the connecting seat, and the controller is electrically connected to the pressure sensor and the rotating motor.

[0015] By adopting the above technical solution, the pressure sensor can move on the track through the connecting seat, and its changed position is limited by bolts, thereby changing the distance from the pressure sensor to the extrusion plate. When the support plate connected to the side plate moves to the extrusion plate to extrude the pressure sensor, the controller controls the motor to rotate in the opposite direction, so that the support plate is separated from the transfer roller and the feeding is stopped. The feeding length of the bar material can be changed, and the applicability is higher.

[0016] The utility model is further configured as follows: the connection between the connecting seat and the track is smooth.

[0017] By adopting the above technical solution, the wear caused by the connecting seat driving the pressure sensor to move is reduced.

[0018] The utility model is further configured as follows: a scale is also installed on the loading rack.

[0019] By adopting the above technical solution, it is convenient to observe the moving distance of the pressure sensor more intuitively and to limit the feeding length more conveniently.

[0020] The utility model is further configured as follows: a universal wheel is installed at the bottom of the loading rack.

[0021] By adopting the above technical solution, the universal wheel facilitates the movement of the loading rack, so that the loading rack can load materials to different sawing machines.

[0022] The beneficial effects of the utility model are as follows: when loading, the supporting assembly moves down and fits with the surface of the transfer assembly, and the transfer assembly starts to drive the supporting assembly to move on the guide plate close to the sawing machine body to complete the loading; when the extrusion plate on the supporting assembly moves to the pressure sensor and squeezes the pressure sensor, the controller controls the supporting assembly to move up and no longer fits with the surface of the transfer assembly, and the loading is no longer continued at this time, thereby limiting the loading length of the bar material, without the need for manual measurement, and with high work efficiency; at the same time, the pressure sensor is installed on the moving assembly, and the position of the fixed point of the pressure sensor can be changed, and the loading length of the bar material can be changed, which has higher applicability.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-3 The utility model provides a loading device for a band saw, comprising a frame 1, a sawing machine body 2 mounted on the frame 1, a loading rack 3 fitted with the frame 1, and a transfer assembly mounted on the loading rack 3, two guide plates 7 are mounted on the loading rack 3, a supporting assembly that can move up and down is movably mounted between the two guide plates 7, an extrusion plate 14 is mounted on the supporting assembly, a moving assembly is mounted on the guide plate 7, a pressure sensor 15 is mounted on the moving assembly, a controller 16 is mounted on the loading rack 3, and the controller 16 is electrically connected to the pressure sensor 15 and the supporting assembly.

[0030] When loading, the supporting assembly moves down and fits with the surface of the transfer assembly. The transfer assembly starts and drives the supporting assembly to move on the guide plate 7 close to the sawing machine body 2 to complete the loading. When the extrusion plate 14 on the supporting assembly moves to the pressure sensor 15 and squeezes the pressure sensor 15, the controller controls the supporting assembly to move up and no longer fits with the surface of the transfer assembly. At this time, the loading is no longer continued, thereby limiting the loading length of the bar material. No manual measurement is required, and the work efficiency is high. At the same time, the pressure sensor 15 is installed on the moving assembly, and the position of the fixed point of the pressure sensor 15 can be changed, and the loading length of the bar material can be changed, which has higher applicability.

[0031] The transfer assembly includes a plurality of transfer rollers 4 rotatably connected to the inner side of the loading rack 3, a belt 5 drivingly connecting two adjacent transfer rollers 4, and a transfer motor 6 installed on the loading rack 3 and driving one of the transfer rollers 4 to rotate. When the transfer motor 6 is started, it drives one of the transfer rollers 4 to rotate. When one of the transfer rollers 4 rotates, the belt 5 drives the other transfer rollers 4 to rotate synchronously, so that the rods placed on the supporting assembly can be loaded.

[0032] The material supporting assembly includes a connecting side plate 8 movably connected to the guide plate 7, a vertical slot 9 provided on the connecting side plate 8, a rotating motor 10 installed on the connecting side plate 8, a screw 11 rotatably connected to the inner wall of the vertical slot 9 and connected to the output shaft of the rotating motor 10, a slider 12 movably connected to the inner wall of the vertical slot 9 and threadedly connected to the outside of the screw 11, and a supporting plate 13 connected between the two sliders 12, an extrusion plate 14 is installed on the connecting side plate 8, and the contact surface between the supporting plate 13 and the transfer roller 4 is designed to increase resistance.

[0033] The bar to be sawed is placed on the support plate 13, and the motor 10 is started to drive the screw 11 to rotate, so that the slider 12 moves up and down in the vertical groove 9, thereby driving the support plate 13 to move up and down and fit or separate from the transfer roller 4. When the support plate 13 fits with the transfer roller 4, the bar is loaded. When the support plate 13 separates from the transfer roller 4, the loading is stopped. The resistance-increasing design facilitates better movement of the support plate 13 on the transfer roller 4.

[0034] The moving component includes a track 17 installed on the loading rack 3, a connecting seat 18 movably installed on the outside of the track 17, a plurality of screw holes 19 opened on the track 17, and bolts 20 threadedly connecting the connecting seat 18 and the track 17 through the screw holes 19, the plurality of screw holes 19 are distributed at equal distances on the track 17, the pressure sensor 15 is installed on the connecting seat 18, and the controller 16 is electrically connected to the pressure sensor 15 and the rotating motor 10.

[0035] The pressure sensor 15 can move on the track 17 through the connecting seat 18, and its changed position is limited by the bolt 20, thereby changing the distance from the pressure sensor 15 to the extrusion plate 14. When the support plate 13 connected to the side plate 8 moves to the extrusion plate 14 to extrude the pressure sensor 15, the controller 16 controls the motor 10 to rotate in the opposite direction, so that the support plate 13 is separated from the transfer roller 4 and the feeding is stopped. The feeding length of the bar material can be changed, and the applicability is higher.

[0036] The connection between the connection seat 18 and the track 17 is smooth, which reduces the wear caused when the connection seat 18 drives the pressure sensor 15 to move.

[0037] A scale 21 is also installed on the feeding rack 3, which is convenient for more intuitive observation of the moving distance of the pressure sensor 15 and more convenient for limiting the feeding length.

[0038] A universal wheel 22 is installed at the bottom of the loading rack 3, and the universal wheel 22 facilitates the movement of the loading rack 3, so that the loading rack 3 can feed materials to different sawing machines.
