Description

Technical Field

[0001] This utility model relates to the technical field of band saw cutting platforms, and in particular to a band saw cutting platform that prevents material jamming. Background Technology

[0002] The woodworking band saw consists of a saw frame, a parallelogram adjustment device or a four-screw adjustment device, a saw grinder, a track, and a lifting support. When the machine is working, the wood is fixed in place, the track is stably fixed on the wood, and the saw is installed on the track. The thickness of the wood to be processed is adjusted by the parallelogram adjustment device, so that the saw can make a planar cut along the wood.

[0003] A horizontal band saw cutting machine with publication number CN217967395U is disclosed. Fixed plates are fixedly mounted at intervals on the combined guide rails of the horizontal band saw body. A lifting mechanism is mounted on the fixed plates. Two fixed frames are fixedly mounted on the fixed plates, and two threaded sleeves are rotatably mounted on the fixed frames. A ring tooth is fixedly installed on the outer wall of the lower end of each threaded sleeve. A screw is threadedly connected inside each threaded sleeve, and the screw passes through the fixed frame. A lifting plate is fixedly mounted on the top of the two screws. A first motor is fixedly mounted on one side of the fixed frame, and a gear is fixedly mounted on the output shaft of the first motor and meshes with the ring tooth for transmission. A pushing mechanism is provided on the lifting plate. This design allows the horizontal band saw to adjust the height of the cut wood board after cutting, and the pushing mechanism pushes the cut wood board down, saving manpower and effectively reducing wood board breakage caused by manual cutting, facilitating the next cutting process.

[0004] The above technical solution facilitates the lifting and removal of materials after cutting. However, when materials are being cut, especially when plates are being cut, it is not conducive to the movement of the cut plates and cannot effectively separate the plates and materials after cutting. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a band saw cutting platform that prevents material jamming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A band saw unloading platform for preventing material jamming includes a band saw assembly, a support platform fixed to the rear end of the band saw assembly, a telescopic adjustment assembly provided on the band saw assembly, an abutment plate installed on the telescopic adjustment assembly, and a turntable rotatably connected to one end of the abutment plate.

[0008] An adjustment mechanism is installed on the support platform, and the adjustment mechanism is connected to the turntable component;

[0009] A drive mechanism is installed at the rear end of the contact plate, and a linkage shaft is provided on the drive mechanism. An opening is opened at the lower end of the turntable, and a pressure mechanism is installed in the opening. A lifting block is provided on the pressure mechanism, and the lifting block is slidably installed in the opening. The linkage shaft is rotatably sleeved on the lifting block, and a pressure roller is fixed at one end of the linkage shaft. A through-hole is opened at the end of the support platform near the band saw assembly, and an auxiliary wheel is rotatably sleeved in the through-hole. The pressure roller is located at the upper end of the auxiliary wheel.

[0010] Compared with the prior art, this application can control the turntable to rotate as needed, thereby driving the pressure roller to move. At the same time, it can also make the pressure roller to rotate so that it comes into contact with the cut plate and gives the plate a force to move away from the band saw assembly. With the cooperation of the lower auxiliary wheel, the cut plate can be moved so as to quickly complete the cutting and unloading operation.

[0011] Preferably, the upper end of the auxiliary wheel is flush with the upper end of the support platform.

[0012] Furthermore, the auxiliary wheels can abut against the lower end of the cut plate, and can also rotate to allow the plate to move. In actual production, the support platform can be set up with a frame structure, and multiple auxiliary wheels can be rotated and sleeved at equal intervals inside, which helps to speed up the unloading operation.

[0013] Preferably, the adjustment mechanism includes a gear fixed to the rear end of the turntable component, the gear component and the turntable component are coaxially arranged, the lower end of the gear component is meshed with a spur rack, the lower end of the spur rack is equipped with an electric telescopic rod, and the electric telescopic rod is fixed to the rear end of the contact plate component.

[0014] Furthermore, the electric telescopic rod can control the movement of its piston rod and ensure the stability of its piston rod after adjustment, so as to drive the gear component to rotate through the rack and pinion. The gear component and the turntable component are coaxially set, which can drive the turntable component to rotate. Moreover, in actual manufacturing, the operator can set the rotation range of the turntable component and control the pressure roller component to move on the side of the turntable component close to the band saw assembly.

[0015] Preferably, the driving mechanism includes a motor assembly installed at the lower end of the support platform, a support groove is provided at the rear end of the contact plate, an elastic telescopic assembly is installed in the support groove, and transmission wheels are installed on the output shaft of the elastic telescopic assembly, the linkage shaft and the motor assembly, and a transmission belt is sleeved on the three transmission wheels.

[0016] Furthermore, the elastic telescopic component consists of a rod fixed in the bearing groove, a block sleeved on the rod, and a spring component. The spring component is fixed to the side wall in the bearing groove and one side of the block. One of the drive wheels is rotated and sleeved on one side of the block, and the other two drive wheels are respectively fixed to the end of the linkage shaft away from the pressure roller and the output shaft of the motor component. The setting of the spring component can fully ensure that the transmission belt is always in a taut state, which helps the transmission.

[0017] Preferably, the pressure-applying mechanism includes a lifting rod fixed to the upper end of the lifting block. The lifting rod is disposed through one end of the side wall inside the opening. A spring is sleeved on the lifting rod, and the two ends of the spring are respectively fixed to the top of the opening and the upper end of the lifting block.

[0018] Furthermore, the lifting rod can push the lifting block away from the axis of the turntable, and when the turntable drives the linkage shaft and the pressure roller, the pressure roller moves towards the support table. During the use of the band saw, the pressure roller will come into contact with the cut plate. At the same time, the lifting rod can adapt to different plate thicknesses so that the pressure roller can fully contact the upper end of the plate and control the rotation direction of the pressure roller, so that the pressure roller can exert a force on the plate it is in contact with towards the support table.

[0019] Preferably, a sliding frame is fixed to the front end of the contact plate, and the turntable is rotatably sleeved on the end of the contact plate away from the band saw assembly. An annular groove is provided at the front end of the turntable, and one end of the sliding frame is slidably installed in the annular groove.

[0020] Furthermore, an arc-shaped plate is fixed at one end of the sliding frame. The arc-shaped plate is located in the annular groove, which can fully ensure the stable operation of the turntable.

[0021] Preferably, both the transmission belt and the transmission wheel are toothed.

[0022] Furthermore, the tooth profile design ensures the stability of power transmission.

[0023] The beneficial effects of this utility model are:

[0024] 1. Through the cooperation of electric telescopic rod, rack and pinion and gear components, the turntable can be deflected. The deflection of the turntable can control the pressure roller to move towards the support table or towards the band saw assembly. Before cutting the material, the pressure roller is adjusted to move towards the band saw assembly. At the same time, it is ensured that the pressure roller is always located in the lower half of the turntable so that there is a certain distance between the pressure roller and the support table to facilitate the passage of material.

[0025] 2. When the band saw assembly is performing cutting operations, the cut plate and material move towards the support platform. At this time, the pressure roller is controlled to move towards the support platform, and the motor assembly is started at the same time. This causes the transmission wheel and transmission belt to work together and drive the pressure roller to rotate through the linkage shaft. This allows the pressure roller to come into contact with the upper end of the cut plate and material. At the same time, the rotation of the pressure roller can provide a force for the plate and material to move towards the support platform.

[0026] 3. The lower ends of the material and the plate will contact the auxiliary wheels, which also helps to ensure the movement of the material and the plate;

[0027] 4. Through the cooperation of spring components, lifting rod components, and lifting blocks, a force can be applied to the lifting blocks to move away from the axis of the turntable component, which facilitates the pressure roller component to fully contact the plate and the material to be cut. The elastic telescopic component can also apply a tensioning force to the transmission belt, which helps to ensure that the transmission belt can move, so as to effectively ensure that all three transmission wheels can rotate under the action of the motor component.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Reference Figure 1-5A band saw unloading platform for preventing material jamming includes a band saw assembly 1, which can cut materials. A support platform 2 is fixed to the rear end of the band saw assembly 1. A telescopic adjustment assembly 3 is provided on the band saw assembly 1. The telescopic adjustment assembly 3 consists of a horizontal shaft slidably installed on the band saw assembly 1 and a screw threaded on one side of the band saw assembly 1. One end of the screw is rotatably sleeved on the rear end of an abutment plate 14. An abutment plate 14 is installed on the telescopic adjustment assembly 3. A turntable 5 is rotatably sleeved on one end of the abutment plate 14. The position of the abutment plate 14 can be adjusted by the operation of the telescopic adjustment assembly 3, and the distance between the abutment plate 14 and the saw blade in the band saw can be controlled so as to cut materials as needed.

[0036] Reference Figure 1-5 An adjustment mechanism is installed on the support platform 2, and the adjustment mechanism is connected to the turntable 5. The adjustment mechanism includes a gear 16 fixed to the rear end of the turntable 5. The gear 16 and the turntable 5 are coaxially arranged. The lower end of the gear 16 meshes with a rack 17. An electric telescopic rod 18 is installed at the lower end of the rack 17. The electric telescopic rod 18 is fixed to the rear end of the contact plate 14. The electric telescopic rod 18 can control the movement of its piston rod and ensure the stability of its piston rod after adjustment, so that the gear 16 can be driven to rotate through the rack 17. The gear 16 and the turntable 5 are coaxially arranged, which can drive the turntable 5 to rotate. Moreover, in actual preparation, the operator can set the rotation range of the turntable 5 and control the pressure roller 4 to move on the side of the turntable 5 close to the band saw assembly 1.

[0037] Reference Figure 1-5 A drive mechanism is installed at the rear end of the contact plate 14. The drive mechanism is equipped with a linkage shaft 12. The drive mechanism includes a motor assembly 22 installed at the lower end of the support platform 2. A support groove 19 is opened at the rear end of the contact plate 14. An elastic telescopic assembly 20 is installed in the support groove 19. A transmission wheel 23 is installed on the output shaft of the elastic telescopic assembly 20, the linkage shaft 12, and the motor assembly 22. A transmission belt 21 is sleeved on the three transmission wheels 23. The elastic telescopic assembly 20 consists of a rod fixed in the support groove 19, a block sleeved on the rod, and a spring component. The spring component is fixed to the side wall of the support groove 19 and one side of the block. One of the transmission wheels 23 is rotatably sleeved on one side of the block. The other two transmission wheels 23 are respectively fixed to the end of the linkage shaft 12 away from the pressure roller 4 and the output shaft of the motor assembly 22. The setting of the spring component can fully ensure that the transmission belt 21 is always in a taut state, which helps the transmission.

[0038] Reference Figure 5 Both the transmission belt 21 and the transmission wheel 23 are toothed; the toothed structure ensures the stability of power transmission.

[0039] Reference Figure 1-5The lower end of the turntable 5 has an opening 13, and a pressure mechanism is installed inside the opening 13. The pressure mechanism has a lifting block 11. The pressure mechanism includes a lifting rod 9 fixed to the upper end of the lifting block 11. The lifting rod 9 is installed through one end of the side wall inside the opening 13. A spring 10 is sleeved on the lifting rod 9. The two ends of the spring 10 are respectively fixed to the top of the opening 13 and the upper end of the lifting block 11. The lifting rod 9 can push the lifting block 11 to move away from the axis of the turntable 5. When the turntable 5 drives the linkage shaft 12 and the pressure roller 4 to move, the pressure roller 4 moves towards the support table 2. During the use of the band saw, the pressure roller 4 will come into contact with the cut plate. At the same time, the lifting rod 9 can adapt to different plate thicknesses so that the pressure roller 4 can fully come into contact with the upper end of the plate and control the rotation direction of the pressure roller 4 so that the pressure roller 4 can apply a force to the plate it is in contact with towards the support table 2.

[0040] Reference Figure 1-5 The lifting block 11 is slidably installed in the opening 13, which can ensure that the lifting block 11 can rise and fall smoothly in the opening 13. The linkage shaft 12 is rotatably sleeved on the lifting block 11, which helps to ensure the rotation of the linkage shaft 12. One end of the linkage shaft 12 is fixed with a pressure roller 4. The pressure roller 4 can be made of rubber material, which can facilitate contact with the plate and the material to be cut, so as to quickly carry out the material feeding operation. The bearing platform 2 has a through hole 15 at one end near the band saw assembly 1. An auxiliary wheel 6 is rotatably sleeved in the through hole 15. The pressure roller 4 is located at the upper end of the auxiliary wheel 6. This helps to make the pressure roller 4 and the auxiliary wheel 6 contact the upper and lower ends of the plate respectively. The upper end of the auxiliary wheel 6 is flush with the upper end of the bearing platform 2. The auxiliary wheel 6 can contact the lower end of the plate after cutting. At the same time, the auxiliary wheel 6 can rotate so that the plate can move. Moreover, in actual production, the bearing platform 2 can adopt a frame structure, with multiple auxiliary wheels 6 rotatably sleeved at equal intervals inside, which helps to carry out the material feeding operation more quickly.

[0041] Reference Figure 1-5 A sliding frame 8 is fixed to the front end of the contact plate 14. The turntable 5 is rotatably sleeved on the end of the contact plate 14 away from the band saw assembly 1. An annular groove 7 is opened at the front end of the turntable 5. One end of the sliding frame 8 is slidably installed in the annular groove 7. An arc-shaped plate is fixed to one end of the sliding frame 8. The arc-shaped plate is located in the annular groove 7, which can fully ensure the stable operation of the turntable 5.

[0042] In this utility model, the position of the contact plate 14 can be adjusted and fixed by the telescopic adjustment component 3, so that one side of the material to be cut is in contact with the contact plate 14, which makes it easier to push the material towards the saw body inside the band saw assembly 1. After the saw body has finished cutting, it will continue to move towards the support table 2.

[0043] The extension of the electric telescopic rod 18 enables the rack 17 to drive the gear component 16 to rotate, and the turntable component 5 drives the lifting block 11 to move the pressure roller component 4 towards the support platform 2, so that the pressure roller component 4 can abut against the upper end of the material and the cut plate. At this time, the rear end of the plate and the material are still connected. Through the action of the motor assembly 22, the transmission belt 21 and the transmission wheel 23 can move, so that the pressure roller component 4 can abut against the upper end of the material and the cut plate, which helps it move towards the support platform 2 to complete the cutting operation.
