Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically a multi-blade saw for cutting solid wood flooring that facilitates waste recycling. Background Technology

[0002] In the solid wood flooring production and processing industry, the cutting process is one of the core links that determines the precision, appearance quality, and material utilization rate of the finished flooring. With consumers' increasing demands for consistent wood grain and standardized dimensions, as well as the cost pressures brought about by the growing scarcity of timber resources, the industry has placed higher demands on the precision control, waste recycling efficiency, and automation level of cutting equipment. Currently, solid wood flooring cutting mainly relies on multi-blade saws, which, through the synchronous operation of multiple sets of saw blades, can complete the longitudinal or transverse cutting of solid wood substrates in one go. Compared with traditional single-blade saws, this significantly improves processing efficiency and has become the mainstream equipment in large-scale production. However, existing multi-blade saws still have certain shortcomings in their use.

[0003] For example, the multi-blade saw for producing wooden packaging boxes proposed in application number CN201922275310.5 relates to the field of sawing machines. It includes a support plate fixedly connected to the support plate, a through hole in the support plate, connecting plates symmetrically arranged within the through hole's inner cavity, a main shaft between the connecting plates, external threads on the outer wall of the main shaft, and multiple cutting blades equidistantly arranged on the outer wall of the main shaft. A first sleeve is slidably sleeved around the cutting blades, the inner cavity of the first sleeve is threaded into the main shaft, and a fixing ring is fixedly sleeved around the first sleeve. A second sleeve is located on one side of the cutting blades, and the inner cavity of the second sleeve is threaded into the main shaft. In actual use, excess waste is easily generated during the cutting of the board. This multi-blade saw does not have a structure for collecting waste, which affects the waste collection effect and causes accumulation on the table. Furthermore, the board needs to be manually pushed during movement, which can easily create safety hazards and reduce safety during use.

[0004] Therefore, we propose a multi-blade saw for cutting solid wood flooring that facilitates waste recycling, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-blade saw for cutting solid wood flooring that facilitates waste recycling, in order to solve the problems mentioned in the background art, which are that the lack of a waste collection structure not only affects the waste collection effect but also leaves waste on the table surface, and requires manual pushing of the boards to move, which can easily cause safety hazards and reduce the safety of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-blade saw for cutting solid wood flooring that facilitates waste recycling, comprising a cutting table, wherein support legs are symmetrically installed at the bottom of both ends of the cutting table;

[0007] Multiple cutting mechanisms are installed at the bottom right end of the cutting table;

[0008] The cutting table has symmetrically opened discharge slots on the left end, and a guide slot is fixedly installed at the bottom of the left end of the cutting table.

[0009] An auxiliary moving mechanism is provided on the top of the cutting table.

[0010] Preferably, the multi-blade cutting mechanism includes a positioning seat fixedly mounted to the bottom right end of the cutting table by screws. A connecting shaft seat is rotatably mounted inside the positioning seat. A transmission rod is inserted into the connecting shaft seat. A drive motor is fixedly connected to the front end of the transmission rod. The drive motor is fixedly connected to the positioning seat on the front side. A slide is sleeved on the outer ring of the transmission rod. A saw blade is fixedly mounted on the outer ring of the slide. There are four sets of saw blades and slides.

[0011] Preferably, the multi-blade cutting mechanism further includes a positioning screw that passes through the slide block, positioning holes are provided at both ends of the transmission rod, the slide blocks at both ends are connected to the positioning holes by positioning screws, and adjustment holes are provided at equal intervals in the middle of the transmission rod, the two sets of slide blocks in the middle are connected to the adjustment holes by positioning screws.

[0012] The above-mentioned structure design, through the linkage design of four sets of sliding blocks and saw blades, and in conjunction with the drive motor, enables the saw blades to operate synchronously. It can not only continue the high-efficiency processing advantage of traditional multi-blade saws in cutting multiple solid wood substrates at one time and meet the needs of large-scale production, but also accurately solve the pain point of inconvenient saw blade spacing adjustment in the background technology by means of the combination structure of positioning screws, positioning holes and adjustment holes.

[0013] The two end slides are fixed by positioning screws and positioning holes at both ends of the transmission rod, ensuring the basic stability of the saw blade installation. The two sets of slides in the middle are connected to equal-spaced adjustment holes by positioning screws. The spacing can be switched by selecting the corresponding adjustment hole according to the floor specifications, which greatly improves the convenience and efficiency of spacing adjustment.

[0014] Preferably, the top of the guide trough corresponds to the discharge trough, and the guide trough is arranged in a right-angled trapezoidal structure.

[0015] The design of the above structure, with the guide trough adopting a right-angled trapezoidal structure and the top corresponding to the cutting table discharge trough, solves the core problems of difficult waste recycling and waste residue on the table surface in the background technology. In the actual cutting process, the generated wood chips and scraps can fall into the corresponding guide trough below through the discharge trough, effectively avoiding waste residue on the cutting table surface. The inclined surface of the right-angled trapezoidal structure can guide the waste to slide down quickly, improving the waste collection effect.

[0016] Preferably, the auxiliary moving mechanism includes limiting seats fixedly installed on the front and rear sides of the cutting table. Support frames are fixedly installed on the top surfaces of both ends of the limiting seats. An electric slide is fixedly installed on the top of the support frame. A slider is slidably installed inside the electric slide. A support base is fixedly connected to the bottom end of the slider. The bottom ends of the support base are slidably connected to the limiting seats.

[0017] Preferably, the auxiliary moving mechanism further includes an electric push rod installed in the middle of the top surface of the support base. The bottom end of the electric push rod is fixedly connected to a lifting plate. An extrusion rod is installed at an equal angle on the bottom surface of the lifting plate. The extrusion rod is located between two adjacent sets of saw blades.

[0018] The above-mentioned structural design uses an electric slide table and slider to move the support base, combined with an electric push rod to drive the lifting plate and the pressing rod to press down. In terms of operational safety, there is no need to manually push the plate. The electric slide table drives the pressing rod to push the substrate forward at a constant speed along the cutting table. Workers do not need to come into close contact with the high-speed saw blade, which completely avoids the safety risk of accidental hand contact. At the same time, automated conveying replaces manual handling, which solves the problem of low operational safety.

[0019] The electric push rod can adjust the pressing distance of the extrusion rod according to the thickness of the substrate, so that the extrusion rod fits tightly against the surface of the substrate, achieving effective pressing in the vertical direction and ensuring the stability of movement.

[0020] Compared with the prior art, the beneficial effects of this utility model are: a multi-blade saw for cutting solid wood flooring that facilitates waste recycling;

[0021] 1. The collaborative recycling structure formed by the discharge chute on the right end of the cutting table and the right-angled trapezoidal guide chute at the bottom of the left end precisely solves the problems of difficult recycling and waste residue on the table caused by the lack of waste collection design in traditional equipment. Wood chips and scraps generated during the cutting process can fall into the corresponding guide chute below through the discharge chute, avoiding waste accumulation from the source. The inclined surface of the right-angled trapezoidal structure can guide the waste to slide down quickly, eliminating the need for manual cleaning of the table. This reduces waste cleaning time, ensures a clean processing environment, improves the waste collection effect, and reduces subsequent waste disposal costs.

[0022] 2. By linking the electric slide, slider, and support base, and combining the lifting plate and pressing rod driven by the electric push rod, a fully automated substrate conveying system is constructed. Compared with the traditional method of manually pushing the board, workers do not need to come into close contact with the high-speed rotating saw blade, completely avoiding the safety hazard of accidental hand contact and greatly improving the safety of use. Moreover, the electric push rod can flexibly adjust the pressing distance of the pressing rod according to the thickness of the substrate, ensuring that the pressing rod is closely attached to the surface of the substrate and achieving stable pressing in the vertical direction. With the electric slide moving the substrate forward at a uniform speed, it can not only avoid the cutting deviation caused by uneven force when pushing manually, but also reduce the intensity of manual labor, and take into account both processing safety and cutting accuracy.

[0030] 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.

[0031] Please see Figure 1-6This utility model provides a technical solution: a multi-blade saw for cutting solid wood flooring that facilitates waste recycling, including a cutting table 1, with support legs 2 symmetrically installed at the bottom of both ends of the cutting table 1, and a multi-blade cutting mechanism installed at the bottom of the right end of the cutting table 1. The multi-blade cutting mechanism includes a positioning seat 3 fixedly installed at the bottom of the right end of the cutting table 1 by screws, a connecting shaft seat 4 rotatably installed inside the positioning seat 3, a transmission rod 5 inserted into the connecting shaft seat 4, a drive motor 21 fixedly connected to the front end of the transmission rod 5, the drive motor 21 fixedly connected to the front positioning seat 3, a slide seat 6 sleeved on the outer ring of the transmission rod 5, a saw blade 7 fixedly installed on the outer ring of the slide seat 6, and four sets of saw blades 7 and slide seats 6. The multi-blade cutting mechanism also includes a positioning screw 8 penetrating through the slide seat 6, positioning holes 9 opened at both ends of the transmission rod 5, the slide seats 6 at both ends connected to the positioning holes 9 by the positioning screw 8, and adjustment holes 10 opened at equal intervals in the middle of the transmission rod 5, the two sets of slide seats 6 in the middle connected to the adjustment holes 10 by the positioning screw 8.

[0032] The design described above allows for flexible adjustment of the relative distance between the four sets of saw blades 7 during the pre-cutting saw blade spacing adjustment stage, based on the specifications of the solid wood flooring to be processed. The slides 6 located at both ends of the transmission rod 5 are connected to the pre-set positioning holes 9 at both ends of the transmission rod 5 by positioning screws 8 passing through the slides 6, achieving basic positioning of the saw blades 7 at both ends and ensuring the stability of the overall cutting structure. The two sets of slides 6 in the middle are fixed by positioning screws 8 and adjustment holes 10 opened at equal intervals in the middle of the transmission rod 5. The operator only needs to screw the positioning screws 8 into the adjustment holes 10 of the corresponding interval to quickly complete the spacing switching of the middle saw blades 7 without additional measurement or complex calibration, thus meeting the cutting requirements of different widths of flooring.

[0033] When the cutting stage begins, the drive motor 21 starts, and its output shaft drives the transmission rod 5, which is fixedly connected to it, to rotate synchronously. Since the transmission rod 5 is rotatably connected to the positioning seat 3 through the connecting shaft seat 4, and the positioning seat 3 is fixed to the bottom right end of the cutting table 1 by screws, the transmission rod 5 maintains a stable coaxiality during rotation, avoiding deviation or shaking. At the same time, the four sets of sliding seats 6 fitted on the outer ring of the transmission rod 5 rotate together with the transmission rod 5, thereby driving the saw blade 7 fixed on the outer ring of the sliding seats 6 to rotate at high speed. At this time, the solid wood substrate to be cut passes through the area of ​​the saw blade 7 at a uniform speed under the drive of the auxiliary moving mechanism. The four sets of high-speed rotating saw blades 7 will simultaneously cut the substrate, which not only ensures the cutting efficiency, but also ensures the consistency of the floor size after cutting through the precise adjustment of the saw blade 7 spacing in the early stage.

[0034] The left end of the cutting table 1 is symmetrically provided with a discharge groove 11, and the bottom of the left end of the cutting table 1 is fixedly installed with a guide groove 12. The top of the guide groove 12 corresponds to the discharge groove 11, and the guide groove 12 is set in a right trapezoidal structure.

[0035] The above design means that in the solid wood flooring cutting operation, the cutting action of the multi-blade cutting mechanism on the substrate will generate waste such as wood chips and scraps. Since the substrate needs to be continuously conveyed along the surface of the cutting table 1 after cutting, when the waste and substrate move to the left end of the cutting table 1, the discharge groove 11 symmetrically opened at the left end of the cutting table 1 will become the outlet channel for the waste, so that the waste falls naturally into the discharge groove 11, or enters the discharge groove 11 under the push of subsequent processing operations, effectively avoiding the waste from remaining on the surface of the cutting table 1 and ensuring the cleanliness of the table surface;

[0036] Meanwhile, the guide trough 12, which is fixedly installed at the bottom left end of the cutting table 1, is precisely aligned with the top of the discharge trough 11, ensuring that all waste falling from the discharge trough 11 can completely enter the guide trough 12. The guide trough 12 adopts a right-angled trapezoidal structure design. The waste entering the guide trough 12 will slide down the inclined inner wall at a uniform speed under its own gravity, and can be directionally conveyed without additional power drive. Finally, it will gather at the bottom of the guide trough 12 or the preset collection device, realizing the centralized recycling of waste, greatly improving recycling efficiency and reducing manual cleaning costs.

[0037] The top of the cutting table 1 is provided with an auxiliary moving mechanism. The auxiliary moving mechanism includes a limiting seat 17 fixedly installed on the front and rear sides of the cutting table 1. A support frame 13 is fixedly installed on the top surface of both ends of the limiting seat 17. An electric slide table 14 is fixedly installed on the top of the support frame 13. A slider 15 is slidably installed inside the electric slide table 14. A support base 16 is fixedly connected to the bottom end of the slider 15. The bottom ends of the support base 16 are slidably connected to the limiting seat 17. The auxiliary moving mechanism also includes an electric push rod 18 installed in the middle of the top surface of the support base 16. A lifting plate 19 is fixedly connected to the bottom end of the electric push rod 18. A pressing rod 20 is installed at an equal angle on the bottom surface of the lifting plate 19. The pressing rod 20 is located between two adjacent sets of saw blades 7.

[0038] In the above-described structure, during the substrate fixing and limiting stage, the solid wood substrate to be cut is first placed on the cutting table 1. Then, the electric push rod 18 installed in the middle of the top surface of the support base 16 is activated. The electric push rod 18 extends according to the thickness of the substrate, driving the lifting plate 19 fixedly connected to its bottom end to move up and down synchronously. This causes the pressing rod 20, which is installed at an equal angle on the bottom surface of the lifting plate 19, to move closer to or away from the substrate. When the pressing rod 20 is in close contact with the surface of the substrate, the electric push rod 18 stops running. At this time, the pressing rod 20 firmly fixes the substrate to the cutting table 1 surface through downward pressure, preventing the substrate from shifting or warping during movement.

[0039] During the automatic conveying and cutting stage, after the substrate is fixed, the electric slide table 14 fixedly installed on the top of the support frame 13 is activated. The slider 15 inside the electric slide table 14 slides at a constant speed along the track of the electric slide table 14. Since the bottom end of the slider 15 is fixedly connected to the support seat 16, and the bottom ends of the support seat 16 are limited and slidably connected to the limiting seat 17, the slider 15 will drive the support seat 16 to move synchronously. Then, through the electric push rod 18 and the lifting plate 19, the pressing rod 20 and the fixed substrate will move forward at a constant speed along the cutting table 1. As the substrate gets closer and passes through the high-speed rotating saw blade 7, the saw blade 7 can cut the substrate. The whole process does not require manual pushing of the substrate, which avoids the safety hazards of manual close contact with the saw blade 7, and ensures the accuracy of the cutting size through constant speed conveying, while reducing the labor intensity of the workers.

[0040] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
