Description

Technical Field

[0001] This utility model relates to the field of panel saw technology, specifically to an anti-clogging material structure. Background Technology

[0002] With the progress of society, the furniture industry has also developed rapidly. Manufacturers need to carry out large-scale production. At present, manufacturers usually use electronic wood saws to cut boards. Compared with the previous electric saws, electronic saws are more efficient and have higher board cutting precision, which greatly improves production output.

[0003] When cutting boards, existing panel saws produce wood strips of varying lengths and widths due to the trimming of the boards. When the width of the wood strips is smaller than the width of the kerf, the wood strips can easily get stuck in the kerf, causing the saw to malfunction. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging structure to solve the problem of wood strip jamming in panel saws.

[0005] This utility model provides an anti-clogging structure applied to a panel saw. The panel saw includes a worktable with a kerf for saw blade movement. The anti-clogging structure includes a controller, a position sensor, and several drive mechanisms disposed at the bottom of the worktable. Each drive mechanism includes a drive component and a stop block located on one side of the kerf. The drive component drives the stop block to press against or move away from the kerf. The position sensor collects the saw blade's travel position information. The controller sequentially controls the on / off state of several drive components based on the travel position information.

[0006] In some embodiments, the bottom of the workbench is provided with several grooves that connect the saw kerfs, and the drive unit and the stop block are both disposed on the grooves.

[0007] In some embodiments, the stop is provided with a buffer pad.

[0008] In some embodiments, the driving element is a cylinder, and the output end of the cylinder is connected to a stop block.

[0009] In some embodiments, the drive unit includes a magnetic switch, wherein when the magnetic switch is de-energized, the stop block presses against the saw kerf; and when the magnetic switch is energized, the stop block moves away from the saw kerf.

[0010] In some embodiments, the magnetic switch includes a top cover, a housing, an armature, a spring, an iron core coil, and a base. The housing has a first aperture, a second aperture, and a third aperture that are interconnected. The first end of the armature has a radially extending head, and the second end of the armature passes through the second aperture and the first aperture in sequence before protruding outside the housing. The top cover has a shaft hole for the armature to pass through, and the second end of the armature passes through the shaft hole and is connected to a stop block. The head of the armature is accommodated in the third aperture. The spring is sleeved on the armature and is located in the first aperture. The iron core coil is disposed on the base, and the base is threadedly connected to the housing.

[0011] The second aperture is smaller than the first aperture, and the first aperture is smaller than the third aperture.

[0012] In some embodiments, the diameter of the second aperture is equal to the diameter of the armature.

[0013] In some embodiments, the drive mechanism is detachably connected to the worktable.

[0014] The technical solution provided by this utility model can include the following beneficial effects:

[0015] The anti-clogging structure provided by this utility model allows the saw blade to move along the saw kerf and cut while the panel saw is working. The position sensor collects the current position information of the saw blade in real time and feeds it back to the controller. The controller controls several driving components to open and close in sequence according to the current position information of the saw blade. While realizing sawing, it can close the saw kerf in time to prevent thinner and longer wood strips from falling in and getting stuck in the saw kerf. Attached Figure Description

[0026] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figures 1 to 3As shown in the figure, an anti-clogging structure provided by this utility model embodiment is applied to a panel saw. The panel saw includes a workbench 1 with a kerf 11 for moving the saw blade 10. The anti-clogging structure includes a controller, a position sensor, and several drive mechanisms 2 disposed at the bottom of the workbench 1. The drive mechanism 2 includes a drive member 20 and a stop block 21 located on one side of the kerf 11. The drive member 20 is used to drive the stop block to press against or move away from the kerf 11. The position sensor is used to collect the travel position information of the saw blade 10. The controller controls the on / off state of several drive members 20 sequentially based on the travel position information.

[0030] In this embodiment, the panel saw, the tooling table, and the saw blade 10 are all existing technologies and are well known to those skilled in the art, so they will not be described in detail here.

[0031] Specifically, several stops 21 are arranged side-by-side on one side of the kerf 11. A position sensor (not shown) is connected to a controller (not shown), and the controller is connected to a drive unit 20. The saw blade 10 travels in the kerf 11 to cut the board. The position sensor monitors the current position of the saw blade 10 in real time and sends this position information to the controller. The controller receives the position information and activates the drive unit 20. The drive unit 20 drives the stops 21 away from the kerf 11, allowing the saw blade 10 to travel in the kerf 11. After the saw blade 10 passes the stop 21 at its current position, the controller controls the drive unit 20 to perform a closing operation, and the stops 21 press against the kerf 11 again. In some embodiments, the initial position of the stops 21 can be against the kerf 11 or away from the kerf 11. The position sensor can be an ultrasonic sensor or a photoelectric position sensor. In specific implementations, different numbers of stops 21 can be set according to actual conditions to adapt to different sawing sizes. In addition, the spacing between the stops 21 can be equal or unequal, and there is no unique limitation here.

[0032] Furthermore, the bottom of the workbench 1 is provided with several grooves 12 that connect to the saw kerf 11, and the drive component 20 and the stop block are both disposed on the grooves 12. The drive component 20 is disposed on the grooves 12, realizing the hidden design of the drive component 20 and improving the aesthetics of the workbench 1. In this embodiment, the drive component 20 is a cylinder, which is connected to an air source, and the air source is connected to a controller. Under the action of the position sensor, the orderly closing of the cylinder is realized.

[0033] Example 2

[0034] The difference from Embodiment 1 is that a magnetic switch is used instead of a cylinder, specifically, as shown in Example 1. Figure 4 As shown, in this embodiment 2, when the magnetic switch is in the de-energized state, the stop block 21 presses against the saw kerf 11; when the magnetic switch is in the energized state, the stop block 21 moves away from the saw kerf 11.

[0035] Furthermore, the aforementioned magnetic switch includes a top cover 201, a housing 202, an armature 203, a spring 204, an iron core coil 205, and a base 206. The housing 202 has a first aperture, a second aperture, and a third aperture that are interconnected. The first end of the armature 203 has a radially extending head. The second end of the armature 203 passes through the second aperture and the first aperture in sequence and then protrudes outside the housing 202. The top cover 201 is provided with a shaft hole for the armature 203 to pass through. The second end of the armature 203 passes through the shaft hole and is connected to a stop block 21. The head of the armature 203 is accommodated in the third aperture. The spring 204 is sleeved on the armature 203 and is located in the first aperture. The iron core coil 205 is disposed on the base 206, and the base 206 is threadedly connected to the housing 202.

[0036] The second aperture is smaller than the first aperture, and the first aperture is smaller than the third aperture.

[0037] Furthermore, the diameter of the second aperture is equal to the diameter of the armature 203.

[0038] Specifically, the housing 202 is made of plastic and is formed sequentially by injection molding, forming a first aperture, a second aperture, and a third aperture. The stop block 21 is opposite to the first aperture of the housing 202, and the base 206 is opposite to the third aperture of the housing 202. The axis of the third aperture is longer than the height of the armature 203 head so that there is redundant space between the armature 203 and the iron core coil 205 for the armature 203 to move axially, or after the housing 202 and the base 206 are threadedly connected, the base 206 has redundant space for the armature 203 to move axially. During assembly, the spring 204 is first placed in the first hole, and the armature 203 is inserted from the third hole into the first hole. The spring 204 is then fixed by screwing the top cover 201 onto the housing 202, with one end of the armature 203 protruding from the top cover 201. The stop block 21 is then installed on the upper end of the armature 203 using threads or bolts. The iron core coil 205 is installed on the base 206, which is threadedly connected to the housing 202, and the housing 202 is then fixed in the groove 12. When the magnetic switch is not energized, the spring 204 is in a relaxed state, and the stop block 21 presses against the saw kerf 11 under the elastic force of the spring 204. When the magnetic switch is powered on, the current flows through the iron core coil 205 and generates a magnetic field. This magnetic force is greater than the spring force of the spring 204. The iron core coil 205 attracts the armature 203, causing the stop block 21 to move away from the saw kerf 11, thereby opening the saw kerf 11 channel. When the saw blade 10 passes the stop block 21 at this position, the controller can close the magnetic switch at that position, thus achieving closure.

[0039] Based on the above specific implementation, lubricating oil can also be added inside the housing 202 to reduce the friction between the housing 202 and the armature 203 and improve the smooth operation of the magnetic switch.

[0040] In addition, a rubber protective sleeve can be provided at the head of the armature 203 to reduce the hard impact between the armature 203 and the iron core coil 205.

[0041] In summary, the anti-clogging structure provided by this utility model, compared with the prior art, has a stop block 21 on the saw kerf 11 to limit the wood strip. Under the action of the position sensor, it achieves orderly closing operation. During the movement of the saw blade 10, it will not hinder the normal sawing operation of the saw blade 10, and avoids the problem of relatively thin and long wood strips getting stuck in the saw kerf 11 and causing the saw blade 10 to jam.
