Description

Technical Field

[0001] The present invention relates to the technical field of electric planers, and particularly to an electric planer with a guiding structure. Background Art

[0002] An electric planer is a machine device that uses a planer blade to plane wood, and is one of the commonly used tools for carpenters and other workers.

[0003] With the progress of society, in order to facilitate the operation of the electric planer by workers, an electric planer with a guide scale structure (also called a guiding structure) has emerged. The guide scale structure can fit the side wall of the wood. Therefore, when using the electric planer, according to the fit between the guide scale structure and the wood, the electric planer can perform straight planing work on the wood. However, the existing guide scale structure can only fit the wood, and if a large amount of wood chips generated during the planing process fall on the traveling route of the guide scale structure, it will affect the movement of the guide scale, and further affect the planing effect on the wood. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an electric planer with a guiding structure, aiming to solve the problems appearing in the above background art.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0075] Embodiment 1

[0076] As Figures 1-3 shown, the present invention discloses a planer with a guiding structure, which consists of a machine body 1 and a planing component. A guiding structure 2 capable of fitting with wood is provided on the machine body 1. The guiding structure 2 at least includes:

[0077] A guiding ruler component 3, which can fit with the side wall of the wood and assist the planer to move;

[0078] An adjusting component 4, used to adjust the distance between the guiding ruler component 3 and the machine body 1;

[0079] An air flow generating component 5;

[0080] Among them, the guiding ruler component 3, the adjusting component 4 and the air flow generating component 5 are all arranged on the machine body 1, and the air flow generating component 5 can at least generate a unidirectional flowing air flow and assist the adjusting component 4 and / or the guiding ruler component 3 to operate;

[0081] When the air flow generating component 5 sends the air flow into the adjusting component 4, the adjusting component 4 controls the guiding ruler component 3 to move away from the machine body 1;

[0082] When the air flow generating component 5 sends the air flow into the guiding ruler component 3, the guiding ruler component 3 sprays the part of the air flow to the position of the traveling path of the guiding ruler and cleans it.

[0083] In this embodiment: The adjusting component 4 includes:

[0084] An adjusting body 40, which has an air cavity that can be inflated or deflated;

[0085] An adjusting block 41, which is slidably arranged in the air cavity and divides the air cavity into an air inlet cavity 42 and an air exhaust cavity 43;

[0086] An adjusting shaft 44, which is installed on the adjusting block 41 through an elastic frame and can be fixed to the guiding ruler component 3;

[0087] Among them, a vent hole 45 communicating the intake cavity 42 and the exhaust cavity 43 is formed on the adjusting block 41, and a first closing ball core 47 controlled by a first closing spring 46 to close the vent hole 45 is provided at the vent hole 45;

[0088] An exhaust port 48 communicating with the exhaust cavity 43 and an intake nozzle 48a communicating with the intake cavity 42 are provided on the adjusting body 40.

[0089] In this embodiment: The elastic frame includes:

[0090] A frame body 490 having a plurality of support feet 491 that can be embedded inside the adjusting block 41 and is slidably connected to the adjusting block 41;

[0091] A return spring 492 is provided on the support feet 491 and is used to drive the frame body 490 away from the adjusting block 41;

[0092] Among them, a sliding port 493 for the sliding installation of the adjusting shaft 44 is provided on the frame body 490.

[0093] In this embodiment, a limiting portion 44a is provided on the adjusting shaft 44.

[0094] Reference Figures 1-3 , this embodiment gives a structural schematic diagram of the adjusting component, and its principle is:

[0095] When the air flow generating component sends gas from the air inlet into the intake cavity and causes the air pressure in the intake cavity to rise, then the adjusting block is pushed towards the exhaust port direction, so as to achieve the purpose of controlling the extending movement of the adjusting shaft;

[0096] When it is necessary to control the adjusting shaft to move towards the intake cavity direction, by pressing the guide scale component and making one end of the adjusting shaft push the first closing ball core towards the intake direction to open the vent hole, at this time the gas in the intake cavity enters the exhaust cavity through the vent hole and further discharges from the exhaust port, so as to achieve the purpose of controlling the retracting movement of the adjusting shaft;

[0097] In this embodiment, when the adjusting block moves and the first closing ball core contacts the adjusting shaft, as long as the adjusting shaft is not pushed by an external force, the adjusting shaft will not push open the first closing ball core, so that the vent hole is closed when the intake cavity intakes air, to ensure the smooth intake work of the intake cavity.

[0098] It should be noted that: The purpose of setting the elastic frame in this embodiment is that when the adjusting block moves to the rightmost side and the intake cavity continues to be inflated, the return spring is compressed, and one end of the adjusting shaft pushes the first closing ball core open, so as to protect the adjusting component and avoid the situation that the air pressure gradually increases due to continuous intake of the intake cavity and the adjusting component bursts.

[0099] Please refer to the following embodiments for the air output component and the guide ruler component involved in this embodiment.

[0100] Embodiment 2. The difference from Embodiment 1 is that this embodiment discloses the guide ruler component of the present invention as follows:

[0101] As shown in Figure 1 and 4 -6, in this embodiment: the guide ruler component 3 includes:

[0102] A guide ruler body 30, connected to the adjusting shaft 44;

[0103] An air jet cavity, formed on the guide ruler body 30 and capable of being supplied with air by the air flow generating component 5;

[0104] Among them, a plugging rod capable of moving out from any end of the air jet cavity is provided in the air jet cavity.

[0105] In this embodiment: the plugging rod includes:

[0106] A rod body 310, slidably arranged in the air jet cavity and hollow inside;

[0107] An air inlet, composed of a first air inlet 311 and a second air inlet 312 formed on the rod body 310. In different modes, the plugging rod can send gas into the rod body 310 through different air inlets;

[0108] An air jet nozzle structure, composed of a first air jet nozzle 313 and a second air jet nozzle 314 formed on the rod body;

[0109] Among them, a threaded cavity communicating with the air jet cavity is provided on the guide ruler body 30, and a limiting bolt 316 capable of restricting the movement of the rod body 310 is provided in the threaded cavity, that is: when one end of the limiting bolt 316 is separated from the rod body 310, the rod body can move freely, and when one end of the limiting bolt 316 contacts and abuts against the outer wall of the rod body 314, it is used to fix the rod body 314;

[0110] The first air jet nozzle 313 and the second air jet nozzle 314 are arranged at intervals, and when the rod body 314 moves, they retract into the air jet cavity or at least one moves out of the air jet cavity.

[0111] In this embodiment: both the first air jet nozzle 313 and the second air jet nozzle 314 include:

[0112] A nozzle body 60, having an air jet channel 61 communicating with the inside of the rod body 310;

[0113] A dispersion body 62, formed in each air jet channel 61 and capable of flowing from the input end to the output end of the air jet channel 61 following the air flow;

[0114] The shunt groove 63 is provided on the inner wall of the jet channel 61;

[0115] When the jet channel 61 jets air, the dispersion body 62 moves from the input end to the output end of the jet channel 61, and the air flow is ejected from each shunt groove 63.

[0116] In this embodiment, the shunt groove 63 is recessed on the inner wall of the jet channel 61. And the shapes of the first jet nozzle and the second jet nozzle in this embodiment are one conical and the other cylindrical. Therefore, the air flow directions of the air flows ejected through different jet nozzles are different, and thus, different cleaning methods can be achieved.

[0117] Reference Figure 1 As well as FIGS. 4-6, this embodiment discloses a schematic diagram of the guide ruler assembly of the present invention, and its principle lies in:

[0118] During use, the guide ruler body is adjusted to control the distance between it and the fuselage through the adjustment component (refer to Embodiment 1) to suit the planing work at different positions of the wood;

[0119] When the guide ruler is in use, the user selects whether to move out the plugging rod inside the guide ruler body according to the planing situation. For example: during slight planing, the plugging rod of this embodiment is not needed, while during heavy planing, since there are more waste chips or scraps generated, the plugging rod can be selected. And the plugging rod of this embodiment has at least the following two modes:

[0120] Firstly, through the adjustment control of the limit bolt, the first jet nozzle of the plugging rod body is exposed outside the jet cavity. When the air flow generating component sends gas into the plugging rod, the air flow passes through the first jet nozzle and jets onto the end face of the wood in contact with the guide ruler, and the wood is cleaned, thereby ensuring the sequence of the movement of the guide ruler body;

[0121] Secondly, through the adjustment control of the limit bolt, both the first jet nozzle and the second jet nozzle of the plugging rod body are exposed outside the jet cavity. When the air flow generating component sends gas into the plugging rod, the air flow passes through the first jet nozzle and the second jet nozzle respectively to clean the end face of the wood in contact with the guide ruler body;

[0122] In the above two modes, the jet nozzle of the first mode is conical. Therefore, when the air flow is ejected, it can jet and clean more concentratedly. And in the second mode, there is another nozzle with a cylindrical structure. Therefore, the ejection direction of the air flow is perpendicular to the wood relative to the conical structure. Therefore, the wood can be better cleaned through two different jetting methods;

[0123] It should be noted that:

[0124] In this embodiment, the dispersant provided in each jet nozzle can not only disperse the gas, but also prevent foreign objects from entering through the jet nozzle. Therefore, it can also achieve the purpose of preventing blockage.

[0125] Embodiment 3 is different from Embodiment 1 and / or Embodiment 2 in that this embodiment discloses an air flow generating component, and the air flow generating component of this embodiment can supply air to the guide ruler component or the adjusting component of Embodiment 1 and / or Embodiment 2 respectively, specifically as follows:

[0126] Such as Figures 1-9 , in this embodiment, the air flow generating component 5 includes:

[0127] An air flow generating container, which is composed of a first container 511 and a second container 512 provided on the fuselage 1;

[0128] A piston, which is composed of a first piston 521 and a second piston 522 that are respectively arranged in the first container 511 or the second container 512 and can move up and down;

[0129] A lifting spring, which is composed of a first lifting spring 531 and a second lifting spring 532 that are respectively arranged in the first container 511 or the second container 512 and are used to drive the first piston 521 or the second piston 522 to rise;

[0130] A piston rod, which is composed of a first piston rod 541 and a second piston rod 542 that are respectively connected to the first piston 521 or the second piston 522;

[0131] Among them, one end of the first piston rod 541 and the second piston rod 542 penetrates out of the air flow generating container, and pressing teeth 55 are provided on the first piston rod 541 and the second piston rod 542;

[0132] A driving wheel 56 that can rotate under the control of a driver (not shown in the figure, a motor structure installed in the fuselage) is further provided on the fuselage between the first piston rod 541 and the second piston rod 542, and driving teeth 560 that can be intermittently engaged with the pressing teeth 55 on the first piston rod 541 or the pressing teeth 55 on the second piston rod 542 are provided on the driving wheel 56.

[0133] In this embodiment, one-way air inlets 80 and one-way air outlets 81 are respectively provided on the first container 511 and the second container 512, and a filter structure is provided at the one-way air inlet 80;

[0134] The one-way air outlet 81 can supply air to the intake cavity 42 (Y branch, through the intake nozzle 48a) or the jet cavity (X branch, through the first air inlet 311 or the second air inlet 312 into the plugging rod) through the air flow cavity formed on the fuselage 1, and a control structure for controlling the air flow cavity to supply air to the jet cavity or the intake cavity 42 is provided on the fuselage 1.

[0135] In this embodiment, the air flow chamber is composed of a main flow chamber communicating with the unidirectional air outlet 81 and shunt chambers 82 respectively communicating with the main flow chamber and respectively communicating with the air inlet chamber or the jet chamber. Among them, the control structure includes:

[0136] An adjustment chamber 83 is formed on the fuselage 1 and communicates with each shunt chamber 82;

[0137] A pressing body 84 is arranged in the adjustment chamber 83 in a liftable manner;

[0138] A pressing spring 85 is arranged between the pressing body 84 and the adjustment chamber 83;

[0139] Among them, an over-flow channel 86 capable of communicating with any shunt chamber 82 is arranged on the pressing body 84.

[0140] In this embodiment, second closing ball cores 88 for controlling the closing of the unidirectional air outlet 81 and the unidirectional air inlet 80 are arranged at both the unidirectional air inlet 80 and the unidirectional air outlet 81 through second closing springs 87 (in this embodiment, taking the unidirectional air inlet 80 as an example, the installation method of the second closing ball core 88 of the unidirectional air outlet 81 is opposite to that of the unidirectional air inlet 80);

[0141] Among them, the filter structure is a flexible film 91 arranged at the unidirectional air inlet 80 and having a plurality of filter holes 90, and the flexible film 91 is pushed outwards by the second closing ball core when the unidirectional air inlet 80 is closed.

[0142] Reference Figures 1-9 , the principle of this embodiment at least includes the following:

[0143] First, the air flow generation method of the air flow generation component is:

[0144] Reference Figure 1 and Figure 7 , the driver is used to control the rotation of the driving wheel, and the driving teeth on the driving wheel cooperate with the pressing teeth arranged on the piston rods on both sides, and the piston rods on both sides perform intermittent descending work under the action of the pressing teeth. The driving teeth on the driving wheel can only cooperate with the pressing teeth on one side of the piston rod, and it cannot contact the piston rods on both sides at the same time. Therefore, when the driving wheel rotates, it can intermittently control the piston rods on both sides to perform intermittent descending;

[0145] When the pressing ruler on the piston rod separates from the driving teeth on the driving wheel, the piston rod will rise due to the lifting spring arranged in the air flow generating container, that is: the driving wheel is used to control the piston to descend, and the lifting spring is used to control the piston to rise. Therefore, the piston makes frequent lifting actions in the air flow generating container to complete the air intake and exhaust work of the air flow container. Specifically: when the piston descends, gas enters the air flow generating container from the one-way air inlet, and when the piston rises, the gas is discharged into the shunt cavity from the one-way air outlet;

[0146] Second, the supply objects of different branches in the shunt cavity of the air flow generating component:

[0147] Reference Figure 2 And Figures 7-8 , in this embodiment, after the air flow generating component generates gas, when it is necessary to send the gas into the air intake cavity of the adjusting component, by pressing the pressing body, the flow-through channel on the pressing body is connected to the shunt cavity of the Y branch, and the shunt cavity of the X branch is closed. At this time, the gas generated by the air flow generating component can be sent into the air intake cavity through the Y branch, and the adjusting component is used to adjust the guiding ruler component;

[0148] When the pressing body is released, the pressing body rises due to the pressing spring, and the filtering channel on the pressing body is connected to the shunt cavity of the X branch, and the shunt cavity of the Y branch is closed. At this time, the gas generated by the air flow generating component enters the plugging rod body through the X branch and is ejected through the first jet nozzle and the second jet nozzle arranged on the plugging rod body.

[0149] The above is the basic principle of the air flow generating component in this embodiment. Based on these basic principles and their cooperation with the guiding ruler component or the adjusting component, this embodiment can complete the adjustment work of the guiding ruler component (refer to Embodiment 1) and the jetting of the guiding ruler component (refer to Embodiment 2);

[0150] The purpose of setting two air flow generating containers in the air flow generating component of this embodiment can realize the intermittent jetting work of the first container and the second container. When the first container or the second container intakes air, the second closing ball core at the one-way air inlet opens, and the one-way air inlet intakes air. The gas passes through the filter holes arranged on the flexible membrane. When the air flow flows, the air flow will make the flexible membrane bend towards the one-way air inlet direction. When the one-way air inlet pauses intake, the second closing ball core resets due to the second closing spring, and the elastic membrane is pushed outwards by the second closing ball core (that is: the elastic membrane bends outwards, and when the elastic membrane bends outwards, the impurities on the elastic membrane are shaken off). In this way, the elastic membrane can be cleaned to avoid the blockage of the filter holes.

[0151] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
