Description

TECHNICAL FIELD

[0001] The present application belongs to the field of woodworking sawing equipment, and particularly relates to a continuous working through type four-edge saw. BACKGROUND

[0002] The conventional wood door cutting process relies on manual operation or low-automation equipment, and has technical bottlenecks such as low processing efficiency, poor size accuracy (error range ±1.5mm or more), and easy production of edge collapse defects. To solve the above problems, the existing technology has developed a numerical control wood door four-edge saw, which carries a multi-directional cutting device through a gantry beam, cooperates with a vacuum adsorption workbench to realize automatic processing, and completes pre-milling and cutting separation through the cooperation of a main saw and a vice saw, thereby significantly improving the processing efficiency and accuracy (accuracy up to ±0.1mm). However, it is found in use that the existing equipment still has the following technical defects:

[0003] Limited positioning accuracy: the mechanical positioning centering device driven by double-sided cylinders has stable pushing force which is easily affected by air pressure fluctuations, and the piston rod motion is not synchronized, which makes it difficult to meet the demand for high-precision processing; poor adaptability of the adsorption system: the overall vacuum adsorption table surface adopts a fixed adsorption area design, when processing a long door blank, the tail adsorption force is insufficient, resulting in a lifting amount; and when processing short materials, the redundant adsorption area accounts for more than 40%, causing energy waste; the above technical deficiencies restrict the development of wood door processing towards higher precision and lower energy consumption, and technical breakthroughs need to be achieved through structural innovation and intelligent control, so it can be seen that the existing technology needs to be further improved and improved. CONTENT OF THE UTILITY MODEL

[0004] The utility model provides a continuous working through type four-edge saw to at least solve or alleviate one or more technical problems in the prior art, or at least provide a beneficial choice.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A continuous working through type four-edge saw, comprising a gantry beam, the gantry beam spans a machine tool base, supporting a cross-cutting device and a longitudinal cutting device, the gantry beam is connected with a portal support structure and both are arranged in parallel, a pneumatic actuator is arranged on the upper side of the horizontal beam of the portal support structure, and rotatable synchronous pulleys are arranged at both ends of the lower side, the two synchronous pulleys are connected through a synchronous belt, and the two parallel parts of the synchronous belt are connected with a first limiting piece and a second limiting piece respectively, wherein the first limiting piece / second limiting piece is connected with the piston rod of the pneumatic actuator, when the piston rod is extended or retracted, the first limiting piece / second limiting piece is driven to move, the synchronous belt is driven to rotate, the second limiting piece / first limiting piece is synchronously moved, so as to realize the synchronous approach or departure of the double limiting pieces.

[0007] The above structure drives the first limiting member and the second limiting member through the pneumatic actuator, and realizes synchronous movement of the two through the synchronous belt, ensuring the accuracy and synchronization of positioning, avoiding the instability of thrust and the problem of asynchronous movement that may exist in the traditional double-sided cylinder drive, thereby improving the machining precision. A single pneumatic actuator is used to drive the two limiting members, which can significantly reduce energy consumption compared to the traditional system that requires two independent driving mechanisms. At the same time, the synchronous belt transmission efficiency is high, further reducing energy consumption. The synchronous movement of the double limiting members ensures the stable center positioning of the plate during the machining process, avoiding deviation and error during the machining process.

[0008] In the preferred implementation, the horizontal beam is provided with a limiting groove, and the first limiting member / second limiting member is connected to the piston rod through the connecting piece passing through the limiting groove. When the piston rod is extended or retracted, the connecting piece can move along the length direction of the horizontal beam in the limiting groove.

[0009] In the preferred implementation, the lower side of the horizontal beam is further provided with two first guide rails, and the first guide rail is configured with a first sliding block, and the first limiting member and the second limiting member are respectively connected to the first sliding block.

[0010] The cooperation of the guide rail and the sliding block provides a stable movement path for the limiting member. When the first limiting member and the second limiting member on the belt move under the drive of the pneumatic actuator, the sliding block smoothly slides along the guide rail, effectively preventing the limiting member from shaking or being unstable during movement.

[0011] In the preferred implementation, the portal support structure is arranged on the front and rear sides of the gantry beam, and the cross-cutting device and the longitudinal-cutting device are located between the portal support structure and the gantry beam.

[0012] In the preferred implementation, the machine tool base is provided with a cutting workbench, and the cutting workbench is equipped with a vacuum suction mechanism. The vacuum suction mechanism includes a movable suction table and a base suction table. The movable suction table is located at the end of the base suction table and can move close to or away from the end of the base suction table to adjust the length of the suction area and adapt to different lengths of the plate.

[0013] When processing a long door blank, the movable suction table moves away from the base suction table, thereby extending the effective suction area and ensuring that the long door blank can have sufficient suction force throughout its length. When processing a short door blank, the movable suction table can be close to the base suction table, thereby reducing the effective suction area and avoiding the energy waste of the redundant suction area in the fixed suction area design. By optimizing the utilization of the suction area, this design helps to reduce the energy consumption of the machine tool during operation, in line with the development trend of energy saving and environmental protection.

[0014] In the preferred implementation, the mobile adsorbing platform is connected with the second sliding rail of the cutting workbench through the second sliding block, the cross cutting device and / or the longitudinal cutting device is provided with a first cylinder, the piston rod of the first cylinder is connected with a pushing piece, and the pushing piece drives the mobile adsorbing platform to move along the second sliding rail.

[0015] In the preferred implementation, a conveying belt mechanism is further included, the conveying belt mechanism is arranged on one side of the vacuum adsorbing mechanism, a support frame of the conveying belt mechanism is connected with the bearing frame, the bearing frame is connected with the piston rod of a second cylinder, the cylinder body of the second cylinder is connected with the strip-shaped base frame of the vacuum adsorbing mechanism, and the second cylinder can act to lift the conveying belt mechanism relative to the vacuum adsorbing mechanism.

[0016] In the preferred implementation, a residual material recycling mechanism is further included, the residual material recycling mechanism includes a recycling conveying belt arranged on the other side of the vacuum adsorbing mechanism, and the cutting residual material falls onto the recycling conveying belt to be sent away from the cutting workbench.

[0017] In the preferred implementation, the cutting workbench is provided with a third guide rail, the vacuum adsorbing mechanism, the conveying belt mechanism and the residual material recycling mechanism form a mobile unit, and the mobile unit is arranged on the third guide rail.

[0018] In the preferred implementation, the cutting workbench is provided with two mobile units, and the two mobile units can approach or move away from each other to adapt to different width sizes of the plate. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium.

[0028] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. However, it is noted that direct connection means that the connection between the two main bodies does not form a connection relationship through an excessive structure, but is connected to form a whole only through the connecting structure. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] In the utility model, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features.

[0030] The utility model will be explained below in combination with the drawings of the specification.

[0031] The specific scheme adopted is:

[0032] As Figures 1-4 shown, the utility model provides a continuous working through type four edge saw, including gantry beam 1, gantry beam 1 straddles machine tool base 2, supports cross cutting device 10 and longitudinal cutting device 11, gantry beam 1 is connected gate type support structure 3 and both parallelly arranged, and the horizontal beam 30 of gate type support structure 3 is equipped with pneumatic actuating mechanism 31 on the upside, and the both ends of the downside are equipped with rotatable synchronous pulley 32, two synchronous pulleys 32 are connected through synchronous belt 33, and the parallel part of synchronous belt 33 is connected first limiting piece 34 and second limiting piece 35 respectively, wherein first limiting piece 34 / second limiting piece 35 connects the piston rod of pneumatic actuating mechanism 31, and when the piston rod retracts, drives first limiting piece 34 / second limiting piece 35 to move, and synchronous belt 33 rotates and drives second limiting piece 35 / first limiting piece 34 to move synchronously, to realize the synchronous approach or away of double limiting pieces.

[0033] The continuous working through type four edge saw of the application drives first limiting piece 34 and second limiting piece 35 through pneumatic actuating mechanism 31, and utilizes synchronous belt 33 to realize the synchronous movement of both, ensures the accuracy and synchronism of positioning, avoids the instability of thrust and the problem of motion out of sync that possibly exist in traditional double-side cylinder drive, thereby improves the machining precision, and utilizes single pneumatic actuating mechanism 31 to drive two limiting pieces, compared with the system that needs two independent drive mechanisms in tradition, energy consumption is reduced significantly.At the same time, the transmission efficiency of synchronous belt 33 is higher, further reduces the energy consumption.The synchronous movement of double limiting pieces ensures the stable center positioning of plate material in the machining process, avoids the deviation and error in the machining process.

[0034] Referring to Figure 3The horizontal beam 30 is provided with a limiting groove 300, and the first limiting member 34 / second limiting member 35 is connected with the piston rod through a connecting piece 301 penetrating the limiting groove 300. When the piston rod is extended or retracted, the connecting piece 301 can move along the length direction of the horizontal beam 30 in the limiting groove 300. The limiting groove 300 is arranged on the horizontal beam 30 and mainly plays a role of guiding and limiting the moving track of the connecting piece 301. The length of the limiting groove 300 should be sufficient to accommodate the entire moving distance of the connecting piece 301 during the extension / retraction of the piston rod. The connecting piece 301 is a key component for connecting the first limiting member 34 / second limiting member 35 with the piston rod. It penetrates the limiting groove 300 and is fixedly connected with the limiting member at one end and connected with the piston rod at the other end. When the pneumatic actuator 31 receives a starting signal, the piston rod starts to extend or retract. Since the connecting piece 301 is connected with the piston rod by penetrating the limiting groove 300, the extension / retraction of the piston rod will drive the connecting piece 301 to move in the limiting groove 300, thereby driving the limiting member to move.

[0035] Further, the lower side of the horizontal beam 30 is also provided with two first guide rails 36, and the first guide rail 36 is provided with a first sliding block 37. The first limiting member 34 and the second limiting member 35 are connected with the first sliding block 37 respectively.

[0036] The cooperation of the guide rail and the sliding block 37 provides a stable moving path for the limiting member. When the first limiting member 34 and the second limiting member 35 on the belt move under the drive of the pneumatic actuator 31, the sliding block 37 smoothly slides along the guide rail, effectively preventing the limiting member from shaking or being unstable during the movement, ensuring that they can accurately move along the predetermined path, thereby realizing the accurate center positioning operation of the plate.

[0037] As a preferred embodiment of the present application, the door type support structure 3 is arranged on the front and rear sides of the gantry beam 1, and the cross cutting device 10 and the longitudinal cutting device 11 are located between the door type support structure 3 and the gantry beam 1. The present application only uses two pneumatic actuator elements, greatly simplifying the structure and reducing the manufacturing cost. The reduction in the number of driving elements also means the reduction in the maintenance work. Through the accurate control of the pneumatic actuator elements, the front and rear door type support structures 3 can realize the accurate positioning of the plate, avoiding the positioning error caused by the large number of cylinders and poor synchronization in the traditional design.

[0038] As a preferred embodiment of the present application, the machine tool base 2 is provided with a cutting workbench, and the cutting workbench is provided with a vacuum suction mechanism 21. The vacuum suction mechanism 21 includes a movable suction table top 210 and a base suction table top 211. The movable suction table top 210 is located at the end of the base suction table top 211 and can move close to or away from the end of the base suction table top 211. Through the movement of the movable suction table top 210, the effective length of the entire suction area can be flexibly adjusted to adapt to the processing requirements of plates of different lengths and sizes.

[0039] When processing long door blanks, the movable adsorption table 210 is moved away from the base adsorption table 211, thereby extending the effective adsorption area, ensuring that the long door blank is subjected to sufficient adsorption force throughout the length. When processing short door blanks, the movable adsorption table 210 can be moved close to the base adsorption table 211, thereby reducing the effective adsorption area, avoiding the energy waste of the redundant adsorption area in the fixed adsorption area design. By optimizing the utilization of the adsorption area, this design helps to reduce the energy consumption of the machine tool during operation, in line with the development trend of energy saving and environmental protection.

[0040] Referring to Figure 2 , the movable adsorption table 210 is connected to the second slide rail 2101 provided on the cutting workbench through the second slide block 2100.

The piston rod of the first cylinder 12 is connected to a pushing piece, and the pushing piece abuts against the movable adsorption table 210 to drive it to move along the second slide rail 2101. The cross-cutting device 10 and / or the longitudinal cutting device 11 are provided with a first cylinder 12, which can move along the length direction of the gantry beam 1 following the cross-cutting or longitudinal cutting. At the same time, these devices can also move along the length direction of the machine tool with the gantry beam 1. The piston rod of the first cylinder 12 is connected to a pushing piece, which provides power for the movement of the movable adsorption table 210. The pushing piece can realize XYZ three-axis direction movement, with high flexibility and accuracy. The pushing piece abuts against the movable adsorption table 210, and drives it to move along the second slide rail 2101 by applying a pushing force or a pulling force.

[0041] As a preferred embodiment of the present application, referring to Figure 1 and Figure 2 , the conveying belt mechanism 23 is provided on one side of the vacuum adsorption mechanism 21.

The cylinder body of the second cylinder 232 is connected to the strip-shaped chassis 22 of the vacuum adsorption mechanism 21. The second cylinder 232 can act to lift the conveying belt mechanism 23 relative to the vacuum adsorption mechanism 21.

[0042] The moving adsorption table 210 of the vacuum adsorption mechanism 21 is moved according to the length of the plate in the initial state, the conveying belt mechanism 23 is located above the vacuum adsorption mechanism 21 and is in a high position, so as to facilitate the feeding of the plate. The moving adsorption table 210 and the base adsorption table 211 of the vacuum adsorption mechanism 21 are in a standby state, and the vacuum adsorption function is not activated. The worker or the automatic feeding system places the plate on the conveying belt mechanism 23. The conveying belt mechanism 23 starts to stably convey the plate to the position directly above the machining position, and then the conveying belt mechanism 23 is lowered: the plate gradually approaches the surface of the vacuum adsorption mechanism 21 until it is in contact with the moving adsorption table 210 or the base adsorption table 211, the first limiting piece 34 and the second limiting piece 35 are driven by the pneumatic actuator 31 of the portal support structure 3 to center the plate, and the vacuum pump is started to activate the vacuum adsorption function. The plate is firmly adsorbed on the moving adsorption table 210 or the base adsorption table 211, which ensures the stability during the subsequent machining process. The cross-cutting device 10 and / or the longitudinal cutting device 11 are moved to the predetermined position and are ready for cutting operation.

[0043] As a preferred embodiment of the present application, the excess material recycling mechanism 24 is further included, and the excess material recycling mechanism 24 comprises a recycling conveying belt arranged on the other side of the vacuum adsorption mechanism 21, and the cutting excess material falls on the recycling conveying belt to be sent away from the cutting workbench.
