Description

Technical Field

[0001] This utility model relates to the field of transverse saw technology, specifically to a lifting saw head assembly for a transverse saw. Background Technology

[0002] Cross-cut saws, as key equipment in panel processing, are widely used in precision cutting in industries such as timber and engineered wood. While mainstream cross-cut saws on the market offer high processing efficiency, their saw head lifting mechanisms have significant limitations. When the saw head is vertically adjusted for processing needs, the top-mounted dust hood cannot automatically follow suit, requiring manual repositioning. This is not only cumbersome and inefficient but also prone to misalignment between the dust hood and the saw head, significantly reducing dust collection effectiveness. Furthermore, existing equipment generally uses a fixed, elongated dust inlet design to accommodate the positional changes caused by the lateral movement of the saw head. While this structure can cover a certain cutting area, it cannot dynamically adjust the suction angle and coverage based on the real-time position of the saw head, leading to significant dust dispersion and poor air quality in the workshop. More seriously, the decreased dust collection efficiency forces the equipment to operate at high power for extended periods just to maintain basic cleaning, increasing energy costs and accelerating wear on key components such as fans, increasing maintenance frequency and production costs, becoming a critical bottleneck restricting production efficiency and environmental compliance. Utility Model Content

[0003] The purpose of this invention is to provide a lifting saw head assembly for a transverse saw, which solves the problems of existing saw head lifting mechanisms that cannot adjust the upper dust cover together, can only be manually adjusted, and can only accommodate long suction ports to adapt to changes in saw head position, resulting in poor dust collection and high energy consumption.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lifting saw head assembly for a transverse saw, comprising a guide rail, a locking airbag mounted on the guide rail, a rack mounted on the guide rail, a saw head assembly mounted on the guide rail, the saw head assembly comprising a fixed plate, a lifting cylinder mounted on the fixed plate, a lifting slider motor mounting plate mounted on the output end of the lifting cylinder, a lifting guide column mounted on the lifting slider motor mounting plate, the lifting slider motor mounting plate being fixedly connected to the fixed plate, a saw head panel mounted on the lifting slider motor mounting plate, a cutting saw mounted on the saw head panel, a marking saw mounted on the saw head panel, a pin cylinder mounted on the fixed plate, a pin fixedly connected to the output end of the pin cylinder, the pin being fixedly connected to the saw head panel, a travel adjustment drive assembly mounted on the fixed plate, a travel gear mounted on the travel adjustment drive assembly, the travel gear meshing with the rack, a dust suction port mounted on the fixed plate, and a slider mounted on the fixed plate, the slider being slidably connected to the guide rail.

[0005] Preferably, the locking airbag is disposed on the top surface of the guide rail and is used to fix the position of the saw head assembly on the guide rail.

[0006] Preferably, the rack extends along the length of the guide rail and meshes with the traveling gear to achieve lateral movement of the saw head assembly.

[0007] Preferably, the lifting cylinder is vertically mounted on the fixed plate and is used to drive the lifting slider motor mounting plate to move the saw head panel up and down.

[0008] Preferably, the lifting guide column vertically penetrates the lifting slider motor mounting plate and is connected to the fixed plate to guide the vertical lifting movement of the saw head panel.

[0009] Preferably, the dust suction port is located on the fixed plate and is used to connect a dust suction device to remove dust generated during cutting.

[0010] Preferably, the cutting saw and the scribing saw are mounted side by side on the saw head panel to simultaneously complete the cutting and scribing operations.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This solution employs a linkage control system between a pin-driven cylinder and a locking airbag to control the protective cover: during position adjustment, the pin-driven cylinder pushes the shaft into the positioning hole of the protective cover for fixation; once in place, the locking airbag releases pressure, allowing the protective cover to move with the saw head, and the pin-driven cylinder retracts the pin and locks it again. This design avoids manual adjustment, solves the problem of inefficient dust collection caused by protective cover misalignment, significantly improves dust collection performance, reduces manual intervention, and enhances production continuity.

[0013] 2. This utility model utilizes a lifting cylinder and guide column to control the saw head's lifting and lowering: when not in operation, the saw blade descends and detaches from the board, avoiding idle wear; when cutting is required, it quickly rises and resets. This design reduces non-working energy consumption and tool wear, extends tool life, and can dynamically adjust the height to adapt to different board thicknesses, improving processing accuracy and equipment versatility, effectively reducing overall production costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A lifting saw head assembly for a transverse saw includes a guide rail 1, a locking airbag 11 disposed on the top surface of the guide rail 1 for fixing the position of the saw head assembly 2 on the guide rail 1, a rack 12 disposed on the guide rail 1, and a saw head assembly 2 disposed on the guide rail 1. The saw head assembly 2 includes a fixing plate 21, a lifting cylinder 22 disposed on the fixing plate 21, a lifting slider motor mounting plate 24 disposed on the output end of the lifting cylinder 22, a lifting guide column 23 disposed on the lifting slider motor mounting plate 24, the lifting slider motor mounting plate 24 being fixedly connected to the fixing plate 21, a saw head panel 25 disposed on the lifting slider motor mounting plate 24, a cutting saw 26 disposed on the saw head panel 25, and a marking saw 27 disposed on the saw head panel 25, with the cutting saw 26 and the marking saw 27 mounted side by side on the saw head panel 25.

[0020] Please see Figure 2-3 The saw head panel 25 is fixedly connected to the saw head panel 25 and is used to simultaneously complete the cutting and marking operations. A pin cylinder 28 is provided on the fixed plate 21. A pin 29 is fixedly connected to the output end of the pin cylinder 28. The pin 29 is fixedly connected to the saw head panel 25. A lifting cylinder 22 is vertically installed on the fixed plate 21 and is used to drive the lifting slider motor mounting plate 24 to move the saw head panel 25 up and down. A lifting guide column 23 vertically penetrates the lifting slider motor mounting plate 24 and is connected to the fixed plate 21 to guide the vertical lifting movement of the saw head panel 25. A walking adjustment drive assembly 210 is provided on the fixed plate 21.

[0021] Please see Figure 2-3The walking adjustment drive assembly 210 is provided with a walking gear 211, which meshes with a rack 12. The rack 12 extends along the length of the guide rail 1 and meshes with the walking gear 211 to realize the lateral movement of the saw head assembly 2. The fixed plate 21 is provided with a dust suction port 212, which is opened on the fixed plate 21 and is used to connect a dust suction device to remove the dust generated during cutting. The fixed plate 21 is provided with a slider 213, which is slidably connected to the guide rail 1.

[0022] The specific implementation process of this utility model is as follows: During use, according to processing requirements, the walking adjustment drive component 210 is activated, driving the walking gear 211 to mesh and rotate along the rack 12 on the guide rail 1, causing the fixed plate 21 and saw head assembly 2 to move laterally to the target position. During the movement, the slider 213 slides along the guide rail 1 to ensure smooth movement. After reaching the designated position, the locking airbag 11 inflates, fixing the position of the saw head assembly 2 on the guide rail 1 to prevent displacement during processing; the lifting cylinder 22 drives the lifting slider motor mounting plate 24 to rise along the lifting guide column 23, causing the saw head panel 25, cutting saw 26, and marking saw 27 to rise to the working height, so that the saw blade contacts the surface of the board, ready for cutting;

[0023] The suction port 212 connects to an external dust collection device, continuously adsorbing dust during the cutting process. When the saw head needs to move laterally, the pin cylinder 28 retracts the pin 29, the locking airbag 11 releases pressure, and the protective cover is unlocked, allowing it to move synchronously with the saw head panel 25. After the movement is complete, the pin cylinder 28 extends the pin 29 again to position itself, the locking airbag 11 inflates and secures the protective cover, ensuring that the suction port 212 always covers the cutting area, improving dust collection efficiency.

[0024] After the saw head is positioned, the cutting saw 26 and the scribing saw 27 start synchronously and complete the cutting and scribing of the board according to the preset path. After processing, the lifting cylinder 22 lowers the saw head, the pin cylinder 28 retracts the pin 29, the locking airbag 11 is depressurized, and the saw head assembly 2 can return to the initial position or move to the next processing point.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
