Abstract
Description
Technical Field
[0001] This utility model relates to the field of building curtain walls, and in particular to a building curtain wall cutting device. Background Technology
[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It is hung up like a curtain, hence the name "curtain wall". It is a lightweight wall structure with decorative effect commonly used in modern large and high-rise buildings. It consists of panels and a supporting structural system. It can have a certain displacement capacity relative to the main structure or a certain deformation capacity itself. It is an exterior building envelope or decorative structure that does not bear the load of the main structure. The required size and shape of the curtain wall vary depending on the application scenario.
[0003] For example, patent number CN217628128U discloses a curtain wall cutting device for building curtain wall construction, including a bracket. Support platforms are fixedly connected to the top of both sides of the bracket, and columns are fixedly connected to the bottom of the bracket. Fixed plates are fixedly connected to both sides of the bracket, and a translation mechanism is provided on the top of the fixed plates. A cutting mechanism is fixedly connected to the translation mechanism, which is used to adjust the position of the cutting mechanism. A lifting device is provided on the surface of the bracket. This utility model relates to the field of building curtain wall technology. This curtain wall cutting device for building curtain wall construction achieves the goal of improving work efficiency by using a lifting device to lift the omnidirectional balls when workers need to adjust the angle of the building curtain wall, which is often large and heavy. Multiple omnidirectional balls are used to lift the building curtain wall, facilitating movement and angle adjustment, thus improving work efficiency.
[0004] For example, patent number CN221622640U discloses a curtain wall cutting device for building curtain wall construction, relating to the field of building curtain wall technology. It includes a workbench with a sliding mechanism installed on its outer wall. This invention utilizes a dustproof mechanism, with a protective cover and dustproof groove movably connected. During use, a centrifugal fan is activated to strongly suction the cutting area between the blade and the curtain wall, collecting the resulting dust and debris. This debris is then isolated by a filter, facilitating centralized cleaning and increasing the device's cleanliness. The dust cover prevents debris from flying during cutting, thus protecting workers' eyes and increasing safety. The sliding mechanism, with a movable connection between the sliding rod and the slider, and a fixed connection between the slider and the sliding plate, allows the curtain wall fixed to it to move during use, completing the cutting and increasing the device's convenience.
[0005] Regarding the above description, the applicant believes the following problems exist: Although the existing curtain wall cutting device can cut curtain walls on-site, it relies on manual pushing for feeding. This not only results in poor positioning accuracy and low efficiency, but more importantly, the clamping force provided by the spring limiting mechanism is weak and cannot stabilize the curtain wall during the cutting process, leading to poor cut quality. Furthermore, the curtain wall is prone to displacement, posing a significant safety risk to the operator. In addition, although the existing curtain wall cutting device integrates a dust removal device, it cannot effectively intercept and remove the flying material debris in the direction of the cutting edge during the cutting process, resulting in poor dust removal effect. Utility Model Content
[0006] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a building curtain wall cutting device with an automatic pushing cutting mechanism to feed and cut a fixed curtain wall. This alleviates the problems of low efficiency and potential danger caused by relying on manual pushing of existing devices, as well as the problem of weak clamping force provided by the spring limiting mechanism alone. It prevents the curtain wall from shifting during the cutting process, ensuring not only the straightness and dimensional accuracy of the cutting line, but also fundamentally eliminating the safety hazards that may be caused by manual pushing, thus improving the safety of workers.
[0007] The objective of this utility model is achieved through the following technical solution:
[0008] A building curtain wall cutting device includes a worktable with a cutting groove. A fixing mechanism is provided at one end of the worktable, and a dustproof mechanism is provided at the other end on the cutting groove. A feeding mechanism that can move along the length of the cutting groove is provided below the worktable. A cutting mechanism is provided on the feeding mechanism, and the cutting part of the cutting mechanism can pass through the cutting groove from bottom to top.
[0009] In one optional embodiment, the fixing mechanism includes a baffle fixedly connected to the surface of the worktable and a movable plate that can slide relative to the worktable. A slider is provided at the bottom of the movable plate, and a fixing bolt is provided on the movable plate. The threaded part of the fixing bolt passes downward through the movable plate and the slider to lock the movable plate to the worktable.
[0010] In one optional embodiment, the dustproof mechanism includes an upper dustproof cover and a lower dustproof cover. The upper dustproof cover is fixedly installed above the cutting groove, and the lower dustproof cover is fixedly installed below the cutting groove. Its bottom is connected to the dust collection box. A fan is fixedly connected to the workbench. The air intake of the fan is connected to the interior of the upper dustproof cover, and a dust filter screen is provided at the air intake.
[0011] In one optional embodiment, the feeding mechanism includes a motor fixedly connected to the bottom of the worktable. The output end of the motor is rotatably connected to a drive wheel. A lead screw parallel to the cutting groove is rotatably connected to the bottom of the worktable. One end of the lead screw is fixedly connected to a driven wheel. The driven wheel and the drive wheel mesh with each other. The motor is used to drive the drive wheel and the driven wheel to rotate the lead screw. A nut block is threaded onto the lead screw. A feed plate is fixedly connected to the nut block. The feed plate is slidably connected to the bottom of the worktable.
[0012] In one optional embodiment, the cutting mechanism includes a second motor fixedly connected to the feed plate, and a circular saw fixedly connected to the output end of the second motor. The second motor is used to drive the circular saw to rotate.
[0013] In one optional embodiment, the baffle is arranged along the centerline of the width direction of the workbench, and an avoidance notch is provided at the position corresponding to the cutting groove, and the movable plate is only arranged on one side of the cutting groove.
[0014] In one optional embodiment, the upper dust cover is semi-circular and divided by a baffle. The half of the upper dust cover near the movable plate has a gap for the curtain wall to pass through, and the half of the lower dust cover near the fixed mechanism completely covers the upper part of the cutting groove. The lower dust cover is semi-circular and completely covers the lower part of the cutting groove. A feed groove for the cutting mechanism to move is provided on one side of the lower dust cover.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. The feeding mechanism driven by the lead screw and nut drives the cutting mechanism. The fixing mechanism adopts a structure that combines a reference baffle with a lockable movable plate, realizing the function of automatically pushing the cutting mechanism to feed and cut the fixed curtain wall. This alleviates the problems of low efficiency and easy danger caused by relying on manual pushing of the feed in existing devices, as well as the problem of weak clamping force provided by the spring limit mechanism alone. It prevents the curtain wall from shifting during the cutting process, which not only ensures the straightness and dimensional accuracy of the cutting line, but also fundamentally eliminates the safety hazards that may be caused by manual pushing, and improves the safety of the staff.
[0017] 2. Through a unique semi-enclosed dustproof mechanism consisting of an upper dust cover, a lower dust cover, and an active dust extraction fan system, negative pressure can be formed near the cutting point to capture most of the cutting dust at the source. The dust is then discharged into the dust collection box through the lower dust cover. This alleviates the problem of existing dust removal devices being unable to intercept and effectively remove material debris splashing in the direction of the cutting edge during cutting, resulting in poor dust removal performance. This significantly improves the working environment and protects the health of operators. Attached Figure Description

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment are all commercially available. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0025] Please refer to Figure 1-5 A building curtain wall cutting device includes a workbench 1 with a cutting groove 101. A fixing mechanism 2 is provided at one end of the workbench 1, and a dustproof mechanism 3 is provided at the other end of the workbench 1 on the cutting groove 101. A feeding mechanism 4 is provided below the workbench 1 and can move along the length of the cutting groove 101. A cutting mechanism 5 is provided on the feeding mechanism 4, and the cutting part of the cutting mechanism 5 can pass through the cutting groove 101 from bottom to top.
[0026] In a preferred embodiment of this utility model, the fixing mechanism 2 includes a baffle 201 fixedly connected to the surface of the workbench 1 and a movable plate 202 that can slide relative to the workbench 1. A slider 203 is provided at the bottom of the movable plate 202, and a fixing bolt 204 is provided on the movable plate 202. The screw portion of the fixing bolt 204 passes downward through the movable plate 202 and the slider 203 to lock the movable plate 202 to the workbench 1, which is beneficial to reliably clamp the curtain wall on the workbench 1.
[0027] In a preferred embodiment of this utility model, the dustproof mechanism 3 includes an upper dustproof cover 301 and a lower dustproof cover 302. The upper dustproof cover 301 is fixedly installed above the cutting groove 101, and the lower dustproof cover 302 is fixedly installed below the cutting groove 101. Its bottom is connected to the dust collection box 304. A fan 305 is fixedly connected to the workbench 1. The air intake of the fan 305 is connected to the interior of the upper dustproof cover 301, and a dust filter 306 is provided at the air intake. This helps to form a semi-enclosed dust removal space, realize the "encirclement" of dust, physically limit the diffusion range of dust, and generate negative pressure inside the cover through the fan 305 to actively suck away the dust.
[0028] In a preferred embodiment of this utility model, the feeding mechanism 4 includes a motor 401 fixedly connected to the bottom of the worktable 1. The output end of the motor 401 is rotatably connected to a drive wheel 402. A lead screw 404 parallel to the cutting groove 101 is rotatably connected to the bottom of the worktable 1. One end of the lead screw 404 is fixedly connected to a driven wheel 403. The driven wheel 403 and the drive wheel 402 mesh with each other. The motor 401 drives the drive wheel 402 and the driven wheel 403 to rotate the lead screw 404. A nut block 406 is threadedly connected to the lead screw 404. A feed plate 405 is fixedly connected to the nut block 406. The feed plate 405 is slidably connected to the bottom of the worktable 1, which is conducive to the smooth movement of the cutting mechanism 5, ensuring the straightness of the cutting line. Driven by the motor 401, it replaces manual pushing and realizes the automation of the cutting process. It not only reduces labor intensity, but more importantly, eliminates the instability of manual pushing.
[0029] In a preferred embodiment of this utility model, the cutting mechanism 5 includes a second motor 501 fixedly connected to the feed plate 405, and a circular saw 502 fixedly connected to the output end of the second motor 501. The second motor 501 is used to drive the circular saw 502 to rotate.
[0030] In a preferred embodiment of this utility model, the baffle 201 is arranged along the centerline of the width direction of the workbench 1, and an avoidance notch is provided at the position corresponding to the cutting groove 101. The movable plate 202 is only arranged on one side of the cutting groove 101, which is beneficial to the movement and cutting of the circular saw 502.
[0031] In a preferred embodiment of this utility model, the upper dust cover 301 is semi-circular, with the baffle 201 as the dividing line. The half of it near the movable plate 202 has a gap for the curtain wall to pass through, and the half of it near the fixing mechanism 2 completely covers the upper part of the cutting groove 101. The lower dust cover 302 is semi-circular, which completely covers the lower part of the cutting groove 101, and a feed groove 303 for the cutting mechanism 5 to move is opened on one side, which helps to form a semi-enclosed dust removal space.
[0032] During operation, the curtain wall panel to be cut is first placed horizontally on the workbench 1. One long side of the panel is pressed against the reference baffle 201 of the fixing mechanism 2. The cutting line is aligned with the blade of the circular saw 502. Then, the movable plate 202 of the fixing mechanism 2 is pushed to slide until the other side of the panel is pressed. The fixing bolts 204 on the movable plate 202 are tightened so that its lower end firmly abuts against the workbench 1, thus firmly fixing the panel between the baffle 201 and the movable plate 202. The fan 305 is started, and the fan 305 begins to generate negative pressure inside the upper dust cover 301 to prepare a dust-free environment for the cutting operation. The motor 501 of the cutting mechanism 5 is started to drive the circular saw 502 to rotate at high speed. The motor 401 of the feeding mechanism 4 is started, and the motor drives the driven wheel 402 and the driven wheel 402 to rotate at high speed. The engagement of 03 drives the lead screw 404 to rotate precisely. The rotating lead screw 404 drives the nut block 406 and the feed plate 405 fixed thereto to move smoothly along the cutting groove 101. The cutting mechanism 5 on the feed plate 405 moves accordingly. The high-speed rotating circular saw blade 502 passes through the cutting groove 101 from bottom to top and makes continuous, straight cuts on the fixed plate above. During the entire cutting process, the dust and debris generated are surrounded by the semi-enclosed space formed by the semi-circular upper dust cover 301 and lower dust cover 302. The suction generated by the fan 305 draws away most of the dust from the upper dust cover 301. After the dust-laden air is filtered by the dust filter 306, clean air is discharged. The dust is trapped and falls into the dust collection box 304 at the bottom of the lower dust cover 302 along with larger debris.
[0033] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.
[0034] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
