Description

Technical Field

[0001] The present invention relates to the technical field of wood board detection, and in particular to a wood board strength detection device for home furnishing production and a detection method thereof. Background Art

[0002] Wooden boards are wooden panels made of complete wood. These boards are strong and durable, with natural textures, and are the best choice for decoration. In furniture production, wooden boards are the main load-bearing objects, and their load-bearing strength is an important parameter.

[0003] For example, a high-density fiber wood strength testing machine with publication number CN117451508A relates to the field of wood strength testing. The high-density fiber wood strength testing machine includes a testing machine body and a support rod installed on the top of the testing machine body. The top of the support rod is fixedly connected to a top frame, and a rotating table is arranged below the top frame. The rotating table is surrounded by pressure measuring plates, toughness measuring blocks and wear-resistant rollers. The rotating table is used to arbitrarily switch between the three testing tools of pressure measuring plates, toughness measuring blocks and wear-resistant rollers. The interior of the rotating table is rotatably connected to a first gear, and the top of the first gear is fixedly connected to a positioning table. The high-density fiber wood strength testing machine can replace the testing tools according to the user's requirements. At the same time, a positioning mechanism is arranged inside the device, so that the user can more conveniently position the tool when switching the tool, so that the testing tool can be kept vertical to the wooden board, so that the tool can detect the characteristics of the wooden board more accurately.

[0004] The above technical solution has some problems in practical application. When detecting the strength of the wooden board, the pressure sensor is directly subjected to the force. In order to ensure that the pressure sensor is not overloaded and damaged, high requirements are placed on the pressure sensor.

[0038] Step 1: Place the wood board at the bottom of the pressure testing component according to the specifications and testing standards of the wood board to be tested;

[0039] Step 2: Strength test: move the pressure test component downward to squeeze the plate;

[0041] Technical effects and advantages of the present invention:

[0042] 1. The present invention can perform pressure detection on the wooden board by setting up the mutual cooperation between the pressure detection component and the anti-overload auxiliary detection component, and at the same time, by controlling the anti-overload auxiliary detection component, the "L"-shaped block and the hinged plate can be limited, thereby realizing the anti-overload protection of the pressure sensor.

[0043] 2. The present invention sets up the mutual cooperation between the pressure detection component and the anti-overload auxiliary detection component. Before the detection, by controlling the electric telescopic column to extend to a preset length, the extension of the electric telescopic column will push the sliding extrusion plate to move upward, and the upward movement of the sliding extrusion plate will push the pushing part to move upward. The upward movement of the pushing part will squeeze the pressure sensor, thereby realizing fault detection of the pressure detection component.

[0044] 3. The present invention can detect the bearing strength of a wooden board when it is placed vertically by setting up the cooperation between a pressure detection component and an anti-overload auxiliary detection component. When the bearing strength of a wooden board when it is placed vertically is detected, one of the pressure detection components is moved downward as a whole, and the arc-shaped elastic part is made to fit with the middle side wall of the vertically placed wooden board. At this time, the arc-shaped elastic part is squeezed and elastically deformed, which will push the second vertical part to slide upward to squeeze the top pressure sensor. At this time, the pressure value is detected. When the wooden board is deformed, the squeezing force on the arc-shaped elastic part will increase or decrease, thereby increasing or decreasing the degree of deformation. The change of the arc-shaped elastic part will cause the pressure value detected by the top pressure sensor to change. When the pressure sensor in the pressure detection component that fits with the middle side wall of the vertically placed wooden board detects a change in the pressure value, it indicates that the vertically placed wooden board is deformed. The pressure detection is stopped, and the pressure value detected by the pressure detection component located at the top of the wooden board is queried, thereby accurately determining the bearing value of the wooden board.

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The present invention provides Figures 1 to 9The device for detecting the strength of wooden boards for home furnishing production shown in the figure comprises two symmetrically arranged pressure detection components 6, and the pressure detection component 6 comprises an inverted "L"-shaped push plate 601; the present invention arranges the "L"-shaped push plate 601, on the one hand, to realize the connection between the pressure detection component 6 and the height adjustment component 5, and on the other hand, to limit the "L"-shaped block 603.

[0057] The hinge plate 602 is disposed on the opposite side of the two pressure detection components 6 , and the middle part thereof is rotatably connected to the “L”-shaped push plate 601 .

[0058] Specifically, the pressure detection component 6 also includes a fixed shaft 608, which is placed on the side opposite to the two height adjustment components 5, and the side away from the height adjustment component 5 is rotatably connected to the hinge plate 602; the present invention realizes the rotatable connection between the hinge plate 602 and the "L"-shaped push plate 601 by setting the fixed shaft 608.

[0059] The two "L"-shaped blocks 603 are distributed in a circular array around the rotation point of the hinge plate 602, and the vertical sections are rotated and slidably connected with the hinge plate 602 through the sliding member 604, wherein the horizontal section of the "L"-shaped block 603 at the top is limitedly slidably connected with the vertical section of the "L"-shaped push plate 601; the present invention restricts the "L"-shaped block 603 to only move up and down by arranging the "L"-shaped block 603 and the "L"-shaped push plate 601 as a limited sliding connection, thereby avoiding the situation where pressure detection cannot be performed due to the synchronous rotation of the two "L"-shaped blocks 603 around the fixed axis 608.

[0060] The free telescopic cylinder 605 is placed between the two "L"-shaped blocks 603. The present invention restricts the movement of the two "L"-shaped blocks 603 by setting the free telescopic cylinder 605, so that they can only move up and down relative to each other.

[0061] The pressure sensor 606 is connected to the side of the horizontal section of the top “L”-shaped block 603 away from the vertical section through a spring expansion cylinder 607 .

[0062] Specifically, the spring telescopic cylinder 607 is placed vertically, and is placed at one end of the horizontal section of the top “L”-shaped block 603 away from the vertical section of the top “L”-shaped block 603 .

[0063] The anti-overload auxiliary detection component 7 includes a receiving groove 701, which is opened on the side of the bottom "L"-shaped block 603 away from the hinge plate 602 and is located at the bottom of the pressure sensor 606; the present invention is used to accommodate the anti-overload auxiliary detection component 7 by setting the receiving groove 701.

[0064] The anti-overload limiter 702 has one end that slides through the sliding member 604 and extends into the hinged plate 602 to be limitedly plugged into the hinged plate 602, and the other end extends into the accommodating groove 701 and is connected to the inner wall of the accommodating groove 701. An elastic portion 7021 is provided at one end of the anti-overload limiter 702 located in the "L"-shaped block 603. The present invention arranges the anti-overload limiter 702, and controls the extrusion assembly 8 to squeeze one end of the elastic portion 7021 of the anti-overload limiter 702, so that the elastic portion 7021 is deformed, and the other end of the anti-overload limiter 702 is pushed to insert into the limit groove 703, thereby realizing anti-overload protection for the equipment.

[0065] Multiple limit grooves 703 cooperate with the anti-overload limit piece 702, and their array is opened on the hinged plate 602; the present invention sets the limit grooves 703, and the limit grooves 703 cooperate with the anti-overload limit piece 702. When the anti-overload limit piece 702 is slidably inserted into the limit grooves 703, the anti-overload protection of the equipment is realized.

[0066] The extrusion assembly 8 is used to extrude the elastic portion 7021 .

[0067] Specifically, the extrusion assembly 8 includes a sliding extrusion plate 802 pushed and moved by the electric telescopic column 801, which is used to squeeze the elastic part 7021. The elastic part 7021 is deformed to limit the anti-overload limiter 702 and the hinged plate 602. The present invention controls the extension and retraction of the electric telescopic column 801. The extension and retraction of the electric telescopic column 801 will drive the sliding extrusion plate 802 to move. The sliding of the sliding extrusion plate 802 will squeeze the elastic part 7021. The elastic part 7021 is squeezed and elastically deformed, so that the end of the anti-overload limiter 702 close to the limiting groove 703 slides into the limiting groove 703, thereby realizing the connection between the limiting groove 703 and the anti-overload limiter 702.

[0068] It also includes a fault detection component 9, which is used to detect the pressure detection component 6 to determine whether the pressure detection component 6 has a fault, and can also assist the pressure detection component 6 to perform pressure resistance testing on a plate placed vertically on the plate surface.

[0069] A slot for placing a wooden board is provided at the bottom of the bottom "L"-shaped block 603 .

[0070] The fault detection component 9 includes a first vertical portion 901, which is placed at the bottom of one end of the sliding extrusion plate 802 away from the anti-overload limiter 702; the present invention realizes connection with the anti-overload limiter 702 on the one hand by setting the first vertical portion 901; on the other hand, it realizes back support for the arc-shaped elastic portion 903.

[0071] The second vertical portion 902 is placed on one side of the first vertical portion 901 close to another group of pressure detection components 6, and is connected to the sliding extrusion plate 802 in a limited sliding manner. The present invention limits the sliding direction of the second vertical portion 902 pushed by the arc-shaped elastic portion 903 after elastic deformation by setting the second vertical portion 902 and the sliding extrusion plate 802 in a limited sliding manner, so that the second vertical portion 902 can only slide up and down.

[0072] The arc-shaped elastic portion 903 is used to connect the first vertical portion 901 and the second vertical portion 902. The present invention sets the arc-shaped elastic portion 903, which cooperates with the first vertical portion 901 and the second vertical portion 902. When the arc-shaped elastic portion 903 is squeezed and deformed, the second vertical portion 902 will slide upward and squeeze the pressure sensor 606. When the pressure sensor 606 detects the pressure value, it indicates that the vertically placed wooden board has been squeezed and deformed.

[0073] The pushing portion 904 is placed on the top of the second vertical portion 902, with its bottom flush with the top surface of the sliding extrusion plate 802, and its top flush with the top surface of the "L"-shaped block 603; the present invention sets the pushing portion 904 and controls the electric telescopic column 801 to extend to a preset length. The extension of the electric telescopic column 801 will push the sliding extrusion plate 802 to slide upward, and the upward sliding of the sliding extrusion plate 802 will push the pushing portion 904 to be squeezed upward. Finally, the pressure sensor 606 detects the pressure value. The detected pressure value is compared with the set value. If it is less than or greater than the set value, it means that the pressure detection component 6 has a fault and needs to be repaired. The set value is changed to a normal state. The electric telescopic column 801 extends to a preset length, and the pressure sensor 606 detects the pressure value.

[0074] The present invention, by providing a fault detection component 9, can not only detect the downward pressure of the middle part of a horizontally placed wooden board, but also detect the downward pressure of a vertically placed wooden board, thereby improving applicability.

[0075] It also includes a base 1, which is used to support the entire detection equipment.

[0076] The gantry 2 is placed above the machine base 1 . The present invention provides the gantry 2 to support the up and down reciprocating motion components and the crossbeam 4 .

[0077] Two up and down reciprocating motion components are respectively placed in the two inner side walls of the door frame 2; specifically, the up and down reciprocating motion components are screw slider mechanisms.

[0078] The crossbeam 4 is placed between the two upper and lower reciprocating components.

[0079] Two groups of height adjustment components 5 are placed on top of the pressure detection components 6 and connected to the crossbeam 4. The present invention can individually control the height of one group of pressure detection components 6 by setting the height adjustment components 5.

[0080] The board detection support assembly 10 is connected to the top of the machine base 1 through a fixing assembly 11. The board detection support assembly 10 is provided in the present invention to support the wood board to be detected during the detection process.

[0081] Specifically, the height adjustment assembly 5 includes an electric telescopic rod 501 , which is placed on the top of the beam 4 , and the telescopic end of the electric telescopic rod 501 passes through the beam 4 and is connected to the “L”-shaped push plate 601 .

[0082] Specifically, the sliding member 604 includes a first cylinder 6041, which is fixedly connected to the "L"-shaped block 603; a second cylinder 6042, whose diameter is larger than that of the first cylinder 6041, is fixedly connected to the first cylinder 6041, is located inside the hinge plate 602, and is slidingly and rotatably connected to the hinge plate 602; the present invention realizes the sliding and rotatable connection between the "L"-shaped block 603 and the hinge plate 602 by setting the sliding member 604.

[0083] The hinge plate 602 is provided with sliding grooves 609 , which are provided at both ends of the hinge plate 602 and are slidably and rotatably matched with the sliding member 604 .

[0084] The plate detection support assembly 10 includes a slide seat 1001 on which a limited slide groove 10011 is provided.

[0085] The two support seats 1002 are slidably connected to the limiting sliding grooves 10011 of the sliding seat 1001.

[0086] The roller 1003 is rotatably connected to the top of the support seat 1002 .

[0087] The fastening bolt 1004 penetrates the support seat 1002 and is threadedly connected to the support seat 1002. The present invention is used to achieve a fixed connection between the support seat 1002 and the slide seat 1001 by providing the fastening bolt 1004.

[0088] The fixing assembly 11 includes a fixing stud 1101 and a nut. A through hole opposite to the fixing stud 1101 is formed in the middle of the sliding seat 1001 .

[0089] It also includes at least four moving wheels, which are placed at the bottom of the base 1 and are not shown in the figure.

[0090] In summary, this device can place the wooden board surface horizontally and perform compressive strength test on the middle part of the horizontally placed wooden board, hereinafter referred to as the compressive strength test of the horizontally placed wooden board surface. It can also place the wooden board surface vertically, press down on the vertically placed wooden board, and test its compressive strength, hereinafter referred to as the compressive strength test of the vertically placed wooden board surface.

[0091] Before the test, since the arc-shaped elastic part 903 is initially exposed in the accommodating groove 701, when the board surface is placed horizontally to test the bearing strength, since the two pressure detection components 6 are at the same height, the arc-shaped elastic parts 903 squeeze each other. When the board surface is placed horizontally to test the bearing strength, the height adjustment component 5 corresponding to one of the pressure detection components 6 can be controlled to drive one of the pressure detection components 6 to slide upward, causing the two arc-shaped elastic parts 903 to be misaligned.

[0092] Before the detection, by controlling the electric telescopic column 801 to extend to a preset length, the extension of the electric telescopic column 801 will push the sliding extrusion plate 802 to move upward, and the upward movement of the sliding extrusion plate 802 will push the pushing part 904 to move upward. The upward movement of the pushing part 904 will squeeze the pressure sensor, and finally the pressure sensor 606 detects the pressure value. The detected pressure value is compared with the set value. If it is less than the set value, it means that the elastic coefficient of the spring telescopic cylinder 607 of the pressure detection assembly 6 has changed or the pressure sensor 606 is faulty, resulting in a small pressure value. If it is greater than the set value, it means that the pressure sensor 606 is faulty.

[0093] When testing the pressure strength of a board placed horizontally, first adjust the slide 1001 so that the middle of the board to be tested is located at the bottom of the pressure detection component 6; then place the board to be tested horizontally on the top of the board detection support component 10, and then control the up and down reciprocating motion component to drive the pressure detection component 6 to move downward until the "L"-shaped block 603 at the bottom of the pressure detection component 6 contacts the board.

[0094] Then continue to move the pressure detection assembly 6 downward, which will cause the bottom "L"-shaped block 603 to move upward. The upward movement of the bottom "L"-shaped block 603 will drive the hinged plate 602 to rotate. The rotation of the hinged plate 602 will drive the top "L"-shaped block 603 to slide downward, and finally squeeze the free telescopic cylinder 605 and the pressure sensor 606, so that the pressure sensor 606 detects the pressure value; thereby realizing the pressure strength detection of the horizontally placed board surface.

[0095] During the detection process, when the pressure value detected by the pressure sensor is greater than the first preset value, the electric telescopic column 801 is controlled to contract, and the contraction of the electric telescopic column 801 will drive the sliding extrusion plate 802 to move, and the sliding of the sliding extrusion plate 802 will squeeze the elastic part 7021. The elastic part 7021 is squeezed and elastically deformed, so that the end of the anti-overload limiter 702 close to the limit groove 703 slides into the limit groove 703, and then the limit groove 703 is plugged with the anti-overload limiter 702. Since the limit groove 703 is plugged with the anti-overload limiter 702, the rotation and sliding between the "L"-shaped block 603 and the hinge plate 602 are limited, and the movement of the "L"-shaped block 603 is limited, and the spring telescopic cylinder 607 can no longer be squeezed, so that the anti-overload protection of the pressure sensor 606 is realized.

[0096] When testing the pressure bearing strength of a board placed vertically, place the board vertically and in the placement slot. Then, adjust the slide 1001 so that the slide 1001 clamps the bottom of the vertically placed board. Then, control the up and down reciprocating motion assembly to drive the pressure detection assembly 6 to move downward until the "L"-shaped block 603 at the bottom of the pressure detection assembly 6 contacts the board. Then, control the height adjustment assembly 5 corresponding to the pressure detection assembly 6 where no board is placed to extend. The extension of the height adjustment assembly 5 will push the corresponding pressure detection assembly 6 to move downward as a whole. The downward movement of the pressure detection assembly 6 will make the arc-shaped elastic portion 903 fit the middle side wall of the vertically placed board. At this time, the arc-shaped elastic portion 903 is squeezed and elastically deformed, which will push the first The second vertical portion 902 slides upward to squeeze the top pressure sensor 606, and a pressure value is detected at this time. During the pressure detection process of the vertically placed wooden board, when the wooden board is deformed, the squeezing force on the arc-shaped elastic portion 903 will increase or decrease, thereby increasing or decreasing the degree of deformation. The change of the arc-shaped elastic portion 903 will cause the pressure value detected by the top pressure sensor 606 to change. When the pressure sensor 606 in the pressure detection component 6 that is in contact with the middle side wall of the vertically placed wooden board detects a change in pressure value, it indicates that the vertically placed wooden board is deformed at this time, and the pressure detection can be stopped. The pressure value detected by the pressure detection component 6 located at the top of the wooden board can be queried, thereby accurately determining the pressure-bearing value of the wooden board.

[0097] The present invention also provides a method for detecting the strength of a wooden board for home production, comprising the following steps:

[0098] Step 1: Place the wood board. According to the specifications and testing standards of the wood board to be tested, place the wood at the bottom of the pressure testing component 6;

[0099] Step 2: strength test, moving the pressure test assembly 6 downward to squeeze the plate;

[0100] Step three, anti-overload protection. During the strength detection process, when the pressure value detected by the pressure detection component 6 is greater than the preset value, the extrusion component 8 is controlled so that the anti-overload auxiliary detection component 7 performs anti-overload protection on the pressure detection component 6.

[0101] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
