Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a novel band saw. Background Technology

[0002] Band saws are commonly used equipment for sawing and cutting timber, especially suitable for sawing irregular shapes of solid wood. Their working principle involves tensioning the band saw blade between the drive and driven saw wheels. A motor drives the drive saw wheel to rotate, which in turn drives the driven saw wheel to rotate synchronously, causing the band saw blade to rotate and thus completing the sawing process.

[0003] However, existing band saws still rely on operators holding the workpiece and pushing it across the worktable during the sawing process. This method has significant drawbacks: firstly, when pushing the workpiece, the operator's hand is prone to accidentally touching the high-speed rotating saw blade, posing a very high safety risk and easily leading to accidents; secondly, manually pushing the workpiece not only results in low work efficiency but also significantly increases the operator's labor intensity, making it difficult to meet the demands of high-efficiency production. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a new type of band saw, which completes the sawing operation by pushing the workpiece to move towards the saw blade through a pusher, which can not only effectively reduce the risk of manual contact and improve operational safety, but also reduce labor intensity and improve work efficiency.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A new type of band saw includes:

[0007] The machine body, on which a worktable is provided;

[0008] A sawing assembly includes a saw blade, two saw wheels, and a drive mechanism. The two saw wheels are spaced vertically along a first direction to form a processing interval. One end of the saw blade is wound around one of the saw wheels, and the other end of the saw blade is wound around the other saw wheel. A linear drive section of the saw blade located between the saw wheels passes through the processing interval to form a saw blade processing section. The saw wheels are used to drive the saw blade to rotate when rotating, so as to guide the saw blade processing section to move along a processing direction.

[0009] The drive mechanism is connected to one of the saw wheels and is used to drive the saw wheel to rotate;

[0010] A pusher is movably connected to the worktable and is used to move closer to or further away from the processing interval in a second direction when subjected to force. The pusher is provided with a positioning part for positioning the workpiece.

[0011] Furthermore, the bottom of the pusher is provided with a slider, and the worktable is provided with a slide rail. The slider and the slide rail slide together to guide the pusher to move in the second direction.

[0012] Furthermore, the worktable is provided with slide rails on both sides, and the bottom of the pusher is provided with at least two sliders. Each pair of sliders is symmetrically distributed on both sides of the pusher and slides in cooperation with the two slide rails respectively.

[0013] Furthermore, the positioning part includes a positioning seat, which has a positioning groove for supporting the workpiece.

[0014] Furthermore, the positioning part includes at least two positioning seats, which are spaced apart along a third direction. Each positioning seat is provided with at least two positioning grooves, which are spaced apart in the second direction.

[0015] Furthermore, it also includes a pressing assembly, which includes a support frame, a pressing component, and a pressing drive component. The support frame includes two support rods, which are respectively located at both ends of the pushing component. The pressing component is located above the positioning part, and both ends of the pressing component are movably connected to the two support rods and can move closer to or further away from the positioning part.

[0016] The pressing drive is used to drive the pressing component to move closer to or away from the positioning part.

[0017] Furthermore, the worktable is provided with a limiting baffle, which extends along the second direction and is used to abut against the workpiece.

[0018] Furthermore, the limiting baffle includes a first plate segment and a second plate segment. The first plate segment extends along the second direction and is used to abut against the workpiece. One end of the second plate segment is connected to one end of the first plate segment, and the other end of the second plate segment is movably connected to the machine body and can move along a third direction, so that the first plate segment can move closer to or further away from the pusher along the third direction.

[0019] Furthermore, the body is provided with a plurality of first through holes, which are spaced apart along the third direction; the second plate segment is provided with a second through hole and a connector, which passes through the second through hole and is detachably connected to one of the first through holes.

[0020] Furthermore, the workbench is provided with a feeding plate, which is inclined from top to bottom along a third direction.

[0021] In summary, the novel band saw provided by this utility model has the following technical effects:

[0022] During sawing operations, the workpiece is placed on the push plate and fixed in place by the positioning part. Then, the operator only needs to apply external force to the push plate to drive it smoothly along a preset track (i.e., the second direction) towards the saw blade processing section, thereby bringing the workpiece closer to the high-speed rotating saw blade and completing the sawing operation. In this way, the workpiece is pushed entirely by the push plate during sawing, eliminating the need for the operator to directly contact the saw blade, effectively reducing the risk of injury to the operator's hands and other limbs, and improving operational safety.

[0023] In addition, compared with the traditional method of manually holding and pushing workpieces, it reduces the load on the operator's arms and the intensity of force exerted, reduces muscle fatigue after long-term work, thereby reducing labor intensity and improving work efficiency.

[0037] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0038] See Figures 1 to 5 This utility model discloses a novel band saw, including a machine body 10, a sawing assembly, and a pusher 50. The machine body 10 is provided with a worktable 11. The sawing assembly includes a saw blade 30, two saw wheels 20, and a drive mechanism 40. The two saw wheels 20 are arranged vertically and vertically along a first direction to form a processing interval 12. One end of the saw blade 30 is wound around one of the saw wheels 20, and the other end of the saw blade 30 is wound around the other saw wheel 20. The linear transmission section of the saw blade 30 located between the saw wheels 20 passes through the processing interval 12 and forms a saw blade processing section 31. When the saw wheel 20 rotates, it drives the saw blade 30 to rotate, so as to guide the saw blade processing section 31 to move along a processing direction. The drive mechanism 40 is connected to one of the saw wheels 20 to drive the saw wheel 20 to rotate. In addition, the pusher 50 is movably connected to the worktable 11. When the pusher 50 is subjected to force, it moves closer to or further away from the processing interval 12 along a second direction. The pusher 50 is provided with a positioning part, which is used to position the workpiece.

[0039] Based on the above structure, taking the height direction of the machine body 10 as the first direction and the length direction of the workbench 11 as an example, during assembly, the two saw wheels 20 are respectively installed on the top and bottom of the machine body 10, and a fixed distance is maintained along the first direction to form a processing interval 12 so that the workpiece can fully contact the saw blade processing section 31 when it passes through.

[0040] Specifically, when the equipment is in its initial state, the pusher 50 rests at the end of the worktable 11 away from the processing interval 12, facilitating safe placement of the workpiece by the worker. During sawing operations, the worker first places the workpiece in the positioning part of the pusher 50, securing the workpiece through the positioning part; then, external force is applied by manual pushing, electric push rods, or cylinders to smoothly move the pusher 50 towards the processing interval 12 in the second direction. When the front end of the workpiece reaches the saw blade processing section 31, the drive mechanism 40 is activated, and the saw wheel 20 rotates under power, driving the saw blade 30 to rotate at high speed, and the saw blade processing section 31 then cuts the workpiece.

[0041] After one round of sawing is completed, the worker drives the pusher 50 to move in the opposite direction in the second direction, moving the workpiece away from the processing interval 12. At this time, the angle or position of the workpiece can be adjusted (such as rotating the workpiece to make oblique cuts or moving the workpiece to make multi-segment cuts), and then the pushing action is repeated to complete the next round of sawing. Continuous processing is achieved through this cyclical operation.

[0042] Throughout the process, the worker operates at the end of the workbench 11, which is far from the processing interval 12, without having to directly contact the high-speed rotating saw blade 30. With the mechanical pushing of the pusher 50, the risk of the hands or other limbs coming into contact with the high-speed rotating saw blade 30 is reduced, improving operational safety and effectively reducing the probability of work-related accidents caused by accidental contact.

[0043] In addition, the pusher 50 moves in a directional manner along the second direction, replacing the traditional manual gripping and pushing, which reduces the load and force exerted by the worker's arm. Combined with the fixing effect of the positioning part, it reduces muscle fatigue after long-term work and significantly reduces labor intensity.

[0044] It should be noted that in this embodiment, the pusher 50 and the worktable 11 can be connected by a sliding connection. For example, two parallel slide rails 111 are installed on the worktable 11 along the second direction. The bottom of the pusher 50 is provided with a matching slider 52. The slider 52 is embedded in the slide rail 111 and can move smoothly. The two ends of the slide rail 111 are provided with limit blocks to prevent the pusher 50 from slipping. In this way, the directional movement of the pusher 50 along the slide rail 111 replaces the traditional manual holding and pushing, which greatly reduces the load and force intensity of the worker's arm and significantly reduces the labor intensity. Of course, the pusher 50 and the worktable 11 can also be connected by a gear and rack transmission. For example, a rack is fixed on the side of the worktable 11, and a gear with a handle is installed on the pusher 50. The gear meshes with the rack, and turning the handle can drive the pusher 50 to move.

[0045] Alternatively, a lead screw nut can be installed at the bottom of the pusher 50, and a lead screw can be installed on the end face of the worktable 11. The lead screw nut and the lead screw are threaded together. The motor drives the lead screw to rotate in both directions, which drives the pusher 50 to move automatically back and forth in the second direction. This eliminates the need for manual pushing of the pusher 50, saving more time and effort.

[0046] In addition, the pusher 50 in this embodiment can be a structure formed by a base or a plate, and the positioning part can be a positioning groove 511 that matches the shape of the workpiece on the pusher 50 to achieve the positioning of the workpiece; of course, it can also be that the pusher 50 is provided with an adjustable clamp, positioning baffle or other structure to position and lock the workpiece.

[0047] Preferably, in this embodiment, the pusher 50 and the worktable 11 are connected by a sliding connection. During assembly, a slider 52 is provided at the bottom of the pusher 50, and a slide rail 111 is provided on the worktable 11. The slider 52 and the slide rail 111 slide together to guide the pusher 50 to move in the second direction.

[0048] Specifically, after the slider 52 is embedded in the slide rail 111, the contact surface between the slider 52 and the inner wall of the slide rail 111 forms a multi-directional constraint, which can effectively limit the instability of the pusher 50 during movement, such as lateral deviation, vertical jumping, or rotation. Thus, when the worker applies an external force to push the pusher 50, the slider 52 will slide linearly along the predetermined trajectory of the slide rail 111. Even if the pusher 50 is subjected to the sawing reaction force transmitted by the workpiece, the lateral support force of the slide rail 111 on the slider 52 can quickly offset this external force, preventing the pusher 50 from deflecting, thereby improving the stability of the entire movement process and allowing the workpiece to approach the processing interval 12 in a preset posture.

[0049] More specifically, the sliding block 52 and the slide rail 111 mainly generate rolling friction or low-friction sliding, and the resistance to be overcome is much smaller than that of sliding friction, thereby reducing the external force applied by the worker. In addition, this structure can evenly distribute the weight of the pusher 50 and the workpiece onto the slide rail 111, reducing the situation where excessive local pressure leads to a sudden increase in frictional resistance, further improving the labor-saving effect, and making it less tiring for workers during long-term operation.

[0050] Furthermore, in this embodiment, the worktable 11 has slide rails 111 on both sides, and the bottom of the pusher 50 has at least two sliders 52. Each pair of sliders 52 is symmetrically distributed on both sides of the pusher 50 and slides into contact with the two slide rails 111 respectively. When the worktable 11 has slide rails 111 on both sides, and the bottom of the pusher 50 has at least two sliders 52, with each pair of sliders 52 symmetrically distributed on both sides of the pusher 50 and sliding into contact with the two slide rails 111 respectively, the symmetrically distributed sliders 52 on both sides and the slide rails 111 form a "double-support" structure. Thus, when the pusher 50 pushes the workpiece, especially when subjected to the reaction force of the saw blade 30 during sawing, the sliders 52 on both sides can bear the lateral load separately, avoiding tilting or "jamming" of the pusher 50 due to unilateral force. This reduces the risk of unilateral offset or wobbling of the pusher 50 and improves the stability of the pusher 50's movement.

[0051] Furthermore, the positioning part includes a positioning seat 51, on which a positioning groove 511 is provided, the positioning groove 511 being used to support the workpiece.

[0052] Specifically, in this embodiment, the positioning groove 511 matches the shape of the workpiece. When the workpiece is placed in the positioning groove 511, the sidewall of the positioning groove 511 will form a multi-directional fit with the surface of the workpiece to effectively limit the lateral displacement of the workpiece. For example, when the positioning groove 511 is a V-shaped structure, after a cylindrical workpiece is placed in, it will naturally fall into the bottom of the V-shaped groove. The inclined sidewalls on both sides will provide two-point support for the workpiece, and the combined effect of gravity and sidewall friction will limit the radial rotation and axial displacement of the workpiece. If it is a rectangular groove, its two vertical sidewalls can fit against two adjacent sides of the plate, and together with the support surface at the bottom of the groove, form a "three-sided positioning" so that the workpiece maintains a predetermined posture during the pushing process.

[0053] In addition, after the workpiece is placed in the positioning groove 511, the workpiece is confined within a fixed area. In this way, the worker can push the workpiece without using his hands to support it, further reducing the risk of his hands getting close to the saw blade 30.

[0054] Furthermore, the positioning part includes at least two positioning seats 51, which are spaced apart along a third direction. Each positioning seat 51 is provided with at least two positioning grooves 511, which are spaced apart in a second direction.

[0055] Specifically, taking the third direction as the horizontal direction perpendicular to the second direction (i.e., the transverse direction) as an example, during assembly, the positioning seats 51, which are distributed at intervals along the transverse direction, can form a stable "two-point support" for the workpiece. In conjunction with the positioning grooves 511 on each positioning seat 51, the weight of the workpiece and the reaction force generated during the sawing process can be distributed to different positions in the transverse direction. For example, when processing long strips of plates, the two ends of the plate are placed on two positioning seats 51 that are spaced apart in the transverse direction. The positioning grooves 511 of each positioning seat 51 steadily support the plate from below. When the saw blade 30 cuts the middle of the plate, the two ends of the plate are prone to tilting upwards due to the force. At this time, the supporting force of the positioning seats 51 can effectively balance this torque, counteract the upward tilting trend, and keep the workpiece stable during the sawing process, making it less prone to shaking or shifting.

[0056] If the third direction is the length of the workpiece, this "two-point support" can also play a role. For longer workpieces (such as long steel pipes and long profiles), two positioning seats 51 spaced apart along their length can support the front and rear ends of the workpiece respectively. The positioning groove 511 of each positioning seat 51 lifts from below, which can effectively reduce the bending deformation of the workpiece due to its own weight, so that the workpiece remains horizontal during the pushing process, thereby ensuring the accuracy of the sawing position.

[0057] Furthermore, each positioning seat 51 has two positioning grooves 511 spaced apart in the second direction (i.e., the feed direction). During sawing operations, two workpieces can be placed simultaneously in the second direction, and the two workpieces are respectively inserted into the two positioning grooves 511 of the same positioning seat 51. With the synchronous pushing of the pusher 50, the two workpieces are simultaneously moved towards the processing interval 12 along the second direction for sawing, eliminating the need for processing them one by one and reducing the auxiliary time for each sawing operation. This indirectly improves production efficiency.

[0058] Furthermore, the new band saw also includes a pressing assembly 60, which includes a support frame 61, a pressing component 62, and a pressing drive component 63. The support frame 61 includes two support rods 611, which are located at both ends of the pusher 50. The pressing component 62 is located above the positioning part, and both ends of the pressing component 62 are movably connected to the two support rods 611. The pressing component 62 can move closer to or away from the positioning part. The pressing drive component 63 is used to drive the pressing component 62 to move closer to or away from the positioning part.

[0059] Specifically, during the sawing process, the worker places the workpiece into the positioning groove 511. At this time, the pressure member 62 is in its initial position away from the positioning part (maintained in a raised state by the pressure drive member 63), which facilitates the smooth placement of the workpiece. Then, the pressure drive member 63 is activated, driving the pressure member 62 to move towards the positioning part along the height direction of the support rod 611 until the lower surface of the pressure member 62 is tightly attached to the upper surface of the workpiece, and a preset pressure is applied (the pressure can be adjusted according to the material of the workpiece; for example, reduce the pressure for brittle materials to avoid damage, and increase the pressure for rigid materials to fix them). After confirming that the workpiece is firmly pressed, the pusher 50 is pushed to move the workpiece towards the processing interval 12. During the sawing process, the pressure member 62 remains in a pressed state. After the sawing is completed, the pressure drive member 63 drives the pressure member 62 away from the positioning part, and the worker can then remove the processed workpiece, completing one work cycle.

[0060] Thus, by applying pressure from above, the pressure member 62 forms a "coordinated constraint" with the positioning groove 511, compensating for the inadequacy of the positioning groove 511's limitation of only being positioned from below and the side. When the workpiece is placed in the positioning groove 511, the pressure member 62 can press the workpiece from above, firmly fixing it between the positioning part and the pressure member 62. This reduces the risk of the workpiece loosening and detaching from the positioning groove 511 during the pushing process. This is especially beneficial for thin sheet metal, easily deformable workpieces, or workpieces with smooth surfaces (such as aluminum alloy profiles), reducing the risk of workpiece displacement due to vibration.

[0061] It should be noted that the pressing drive 63 in this embodiment can be selected from existing pneumatic cylinders, hydraulic cylinders, electric push rods or manual cranks, etc., to drive the pressing component 62 to move closer to the positioning part along the support rod 611.

[0062] Furthermore, the worktable 11 is provided with a limiting baffle 13, which extends along the second direction and is used to abut against the workpiece.

[0063] Specifically, after the workpiece is placed in the positioning groove 511 of the pusher 50, one end of the workpiece is abutted against the limiting baffle 13. This quickly determines the initial position of the workpiece in the second direction, ensuring that the extension length of different workpieces is consistent during clamping. When processing a batch of workpieces requiring uniform length, simply align the same side of each workpiece with the limiting baffle 13. The dual constraint of the positioning groove 511 and the limiting baffle 13 improves the positioning accuracy before sawing, reduces the time spent on manual measurement and alignment, and increases clamping efficiency.

[0064] Furthermore, the limiting baffle 13 includes a first plate segment 131 and a second plate segment 132. The first plate segment 131 extends along a second direction and abuts against the workpiece. One end of the second plate segment 132 is connected to one end of the first plate segment 131, and the other end of the second plate segment 132 is movably connected to the machine body 10. The second plate segment 132 can move along a third direction so that the first plate segment 131 can move closer to or further away from the pusher 50 along the third direction.

[0065] Specifically, since the second plate segment 132 can move along a third direction (a horizontal direction perpendicular to the second direction), when processing workpieces of different widths or diameters, simply adjusting the position of the second plate segment 132 will change the distance between the first plate segment 131 (the part that abuts against the workpiece) and the positioning part of the pusher 50. For example, when processing narrow plates, the first plate segment 131 is moved closer to the pusher 50, so that both sides of the workpiece are constrained by the first plate segment 131 and the sidewall of the positioning groove 511, respectively; when processing wide plates, the first plate segment 131 is moved away from the pusher 50, leaving sufficient space for the workpiece and reducing the possibility that wide workpieces cannot fit the positioning reference due to the fixed position of the limiting baffle 13, or that the gap between the narrow workpiece and the baffle is too large and loses its constraining effect. This adjustable feature allows the limiting baffle 13 to be adapted to various specifications of workpieces without replacement, greatly improving the versatility of the equipment.

[0066] It should be noted that the first plate segment 131 and the second plate segment 132 can be connected by welding or integral molding. During assembly, a strip-shaped hole extending along the third direction can be opened on the body 10, and the second plate segment 132 is fixed to the body 10 by bolts passing through the strip-shaped hole. When the bolts are loosened, the second plate segment 132 can move freely along the length direction of the strip-shaped hole (third direction). After it is in place, tightening the bolts will lock the position.

[0067] Alternatively, a strip-shaped hole extending along a third direction can be provided on the second plate segment 132, while multiple mounting holes (such as threaded holes or through holes) are arranged in the same direction on the machine body 10. The connection between the two is achieved through the cooperation of bolts and nuts. The length of the strip-shaped hole needs to be designed according to the maximum adjustment range required by the first plate segment 131, so that the length of the strip-shaped hole is sufficient to cover the positional variation range corresponding to different specifications of workpieces. The mounting holes on the machine body 10 are distributed according to the preset adjustment levels, and the spacing between adjacent holes can be set according to the common workpiece specification differences. When it is necessary to adjust the position of the first plate segment 131, first loosen the connecting bolts and nuts, so that the second plate segment 132 can slide freely along the length direction (third direction) of its own strip-shaped hole. During the sliding process, the relative position of the strip-shaped hole and the mounting hole of the machine body 10 changes. After the first plate segment 131 moves to the target position, pass the bolt through the strip-shaped hole and align it with the corresponding mounting hole on the machine body 10, and tighten the nut to complete the fixation.

[0068] Alternatively, a nut seat can be fixed on the body 10, and a lead screw can be connected to the end of the second plate segment 132, with the lead screw threadedly engaging with the nut seat. When the lead screw is rotated, the threaded transmission converts the rotational motion into linear motion (along a third direction) of the second plate segment 132.

[0069] Preferably, the body 10 is provided with a plurality of first through holes 14, which are spaced apart along a third direction; the second plate segment 132 is provided with a second through hole 1321 and a connector, which passes through the second through hole 1321 and is detachably connected to one of the first through holes 14.

[0070] Specifically, during use, the connectors (such as nuts or bolts) must first be removed from the currently connected first through hole 14 and second through hole 1321, thus giving the second plate segment 132 the freedom to move along a third direction. Next, the second plate segment 132 is pushed to move along a third direction, and the second through hole 1321 is aligned with the first through hole 14 at other target positions according to the required adjustment of the distance between the first plate segment 131 and the pusher 50. For example, when processing wider pieces of wood, the second plate segment 132 needs to be moved away from the pusher 50 so that the second through hole 1321 is aligned with the outermost first through hole 14; when processing narrower pieces of wood, it is moved closer to the pusher 50 to align with the innermost first through hole 14.

[0071] Finally, the connector is re-passed through the aligned second through hole 1321 and the first through hole 14, and tightened (such as by tightening bolts and nuts). At this time, the second plate segment 132 is re-fixed on the machine body 10, and its position adjustment is completed, thereby driving the first plate segment 131 to stabilize in the new limit position.

[0072] Furthermore, the workbench 11 is provided with a feeding plate 15, which is inclined from top to bottom along a third direction.

[0073] During assembly, the unloading plate 15 is positioned on the side closest to the processing interval 12. In this way, after the sawn workpiece leaves the processing area, it will naturally slide onto the unloading plate 15 under its own weight and slide down the inclined surface towards a pre-designated collection area (such as a material bin or conveyor belt). This process eliminates the need for manual picking up of workpieces one by one, shortening the process interval time and effectively improving overall processing efficiency.

[0074] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
