Description

Technical Field

[0001] The present invention belongs to the technical field of composite layer pasting and positioning, specifically a calcium silicon board composite layer pasting and positioning device and a positioning method thereof, and achieves structural optimization of the calcium silicon board composite layer pasting and positioning device by optimizing the structure of the positioning component of the pasting and positioning device. Background Art

[0002] In current building decoration projects, there are many wood veneer designs in the fields of public decoration and home decoration. At present, the market mainly uses calcium silicate board as the base to manufacture wood veneer decorative panels. Calcium silicate board is a porous material mainly composed of gypsum, which has good performance and fire retardant properties. The processing process of wood veneer decorative panels is roughly divided into the following steps: first, the calcium silicate board is cleaned, leveled, sanded, dried, and glued. Then, the decorative wood grain paper composited with aluminum foil and kraft paper is adhered to the surface of the calcium silicate board base with adhesive. The wood veneer decorative panels are made by hot pressing to completely cure the glue and ensure that the surface board and the base board are well bonded. The defects on the surface after hot pressing are repaired to ensure that there is no overlap or gap on the board surface, thus obtaining a complete wood veneer finished product.

[0003] The existing calcium silicate board composite layer pasting device can achieve the effect of pasting wood grain paper onto the calcium silicate board, but there are still the following problems:

[0004] 1. Existing calcium silicate board composite layer pasting devices often require manual alignment and pasting of the composite layer and the calcium silicate board. During the process, manual errors will inevitably cause the composite layer to be positioned incorrectly on the calcium silicate board, causing the composite layer to be pasted crookedly on the calcium silicate board, resulting in a decrease in the quality of the finished wood veneer.

[0005] 2. The existing calcium silicate board composite layer pasting device can often only adapt to one size of calcium silicate board. For calcium silicate boards of different sizes, multiple product lines need to be established to paste the composite layers, which requires the purchase of additional machines, greatly increasing production costs. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a calcium silicate board composite layer pasting and positioning device and a positioning method thereof, so as to solve the problem that the existing calcium silicate board composite layer pasting device needs to establish multiple product lines to process calcium silicate boards of different sizes, thereby increasing production costs, and the problem that the calcium silicate boards are inaccurately positioned due to manual operation errors, resulting in poor quality of the finished wood veneer products.

[0007] The present invention provides the following technical solutions:

[0009] A base, a conveying plate frame is fixedly connected to the top of the base, a main motor is fixedly connected to the top of the base, a rotating motor 1 is fixedly connected to the inner and outer walls of the conveying plate frame; a conveying roller is fixedly connected to the main shaft of the rotating motor 1;

[0010] The pasting component includes a bracket one, a composite layer reel, a composite layer guide roller and a heating roller. The bracket one is fixedly connected to the top of the base, the composite layer reel is rotatably connected to the bracket one, the composite layer guide roller is rotatably connected to the bracket one, and the heating roller is fixedly connected to the bracket one.

[0011] Furthermore, a positioning assembly is provided on the top of the base, and the positioning assembly includes a bracket two, a slide groove and a bracket three. The bracket two is fixedly connected to the top of the base, the slide groove is opened on the inner outer wall of the bracket two, and the bracket three is slidably connected to the inner wall of the slide groove. The shape of the bracket three is an eight-shaped opening facing the entry direction of the calcium silicate board.

[0012] Furthermore, a sensor is fixedly connected to the inner wall of the slide groove, a spring is fixedly connected to the outer wall of the sensor, and the spring is fixedly connected to the outer wall of the bracket three. The sensor can preferably be a pressure sensor.

[0013] Furthermore, a long groove is provided on the inner outer wall of the bracket three, and a roller is rotatably connected to the inner wall of the long groove, and the roller is used to further guide the calcium silicate board to move forward.

[0014] Furthermore, a buffer layer is fixedly connected to the outer wall of the roller, and the buffer layer can preferably be an air bag, which can reduce the impact force on the calcium silicate board.

[0015] Furthermore, a centering component is provided on the inner and outer walls of the conveying plate rack, and the centering component includes a rotating motor 2 and an electric telescopic rod 1. The rotating motor 2 is fixedly connected to the inner and outer walls of the conveying plate rack, and the electric telescopic rod 1 is fixedly connected to the main shaft of the rotating motor 2.

[0016] Furthermore, the end of the electric telescopic rod is fixedly connected to a limit block, and the shape of the limit block can preferably be a beveled cylinder. The limit block is used to keep the calcium silicate board in the center position by rotating itself.

[0017] Furthermore, a cutting assembly is provided on the inner outer wall of the bracket one, and the cutting assembly includes a rotating motor three, an electric telescopic rod two and a blade. The rotating motor three is fixedly connected to the inner outer wall of the bracket one, the electric telescopic rod two is fixedly connected to the main shaft of the motor three, and the blade is fixedly connected to the end of the electric telescopic rod two.

[0018] Furthermore, the cross-sectional shape of the blade is circular to meet the requirements of rotary cutting of composite layers.

[0019] The steps of the positioning device and positioning method for the calcium silicate board composite layer are as follows:

[0020] S1: The main motor on the base starts to work, driving the main shaft of the rotating motor 1 on the conveyor plate rack to rotate, driving the conveyor roller to start rotating, and the calcium silicon plate is continuously pushed forward by the rotating conveyor roller. Bracket 3 slides in the slide groove of bracket 2 under the oblique thrust of the calcium silicon plate. Bracket 3 squeezes the sensor through the spring. At the same time, the inner wall of the slide groove also supports the sensor to cause a reaction force on the spring, clamping the calcium silicon plate between the two brackets 2, so that it can adapt to calcium silicon plates of different sizes.

[0021] S2: The sensor records the pressure changes given to it by the spring in real time. According to Hooke's law F (pressure magnitude) = k (spring constant) x (spring length change), x (spring length change) is calculated, thereby obtaining the distance that the two brackets three slide along the slide groove respectively. The sum of the distances is used to obtain the width of the calcium silicon board. Based on this data, the electric telescopic rod 1 in the centering component is extended to a position that can just clamp the calcium silicon board. Then, the motor 2 is turned to start and drive the electric telescopic rod 1 to drive the limit block to start rotating, so that the calcium silicon board always remains in the center position, achieving a stable centering positioning effect for the calcium silicon board.

[0022] S3: The electric telescopic rod 2 in the cutting assembly is extended according to the width data of the calcium silicate board in S2, so that the distance between the two blades fixedly connected to the two electric telescopic rods 2 is exactly the width of the calcium silicate board. At this time, the motor 3 is rotated to drive the electric telescopic rod 2 to drive the blade to rotate, and the composite layer coming out of the composite layer roll is cut into the same width as the calcium silicate board.

[0023] S4: When the pressure increases to a certain value and no longer changes, the sensor sends a signal to start the composite layer guide roller to rotate and transport the composite layer on the composite layer roll that is consistent with the width of the calcium silicate board to between the heating roller and the calcium silicate board. The heating roller presses the composite layer on the surface of the calcium silicate board base layer and solidifies the glue between the composite layer and the calcium silicate board by hot pressing, thereby making a wood veneer decorative board. Then the finished wood veneer board is transported away from the pasting assembly by the conveyor roller, and the pasting work is completed.

[0042] A positioning assembly 7 is provided on the top of the base 1, and the positioning assembly 7 includes a second bracket 71, a slide 72 and a third bracket 73. The second bracket 71 is fixedly connected to the top of the base 1, and the slide 72 is opened on the inner outer wall of the second bracket 71. The third bracket 73 is slidably connected to the inner wall of the slide 72. The shape of the third bracket 73 is an eight-shaped opening facing the entry direction of the calcium silicon board to guide the calcium silicon board to enter smoothly.

[0043] A sensor 74 is fixedly connected to the inner wall of the slide groove 72, a spring 75 is fixedly connected to the outer wall of the sensor 74, and the spring 75 is fixedly connected to the outer wall of the bracket three 73. The sensor 74 can preferably be a pressure sensor for collecting the pressure of the bracket three 73 on the inner wall of the slide groove 72.

[0044] A long groove 76 is provided on the inner outer wall of the bracket 3 73 , and a roller 77 is rotatably connected to the inner wall of the long groove 76 , and the roller 77 is used to further guide the calcium silicate board to move forward.

[0045] A buffer layer 78 is fixedly connected to the outer wall of the roller 77. The buffer layer 78 can preferably be an air bag to reduce the impact force on the calcium silicate board and protect the calcium silicate board.

[0046] A centering component 8 is provided on the inner and outer walls of the conveying plate rack 2. The centering component 8 includes a second rotating motor 81 and an electric telescopic rod 1 82. The second rotating motor 81 is fixedly connected to the inner and outer walls of the conveying plate rack 2, and the electric telescopic rod 1 82 is fixedly connected to the main shaft of the second rotating motor 81.

[0047] The end of the electric telescopic rod 82 is fixedly connected to a limit block 83. The shape of the limit block 83 can preferably be a beveled cylinder. The limit block 83 is used to keep the calcium silicate board in the center position by rotating itself, thereby achieving a positioning effect.

[0048] A cutting assembly 9 is provided on the inner outer wall of the bracket 1 61, and the cutting assembly 9 includes a rotating motor 3 91, an electric telescopic rod 2 92 and a blade 93. The rotating motor 3 91 is fixedly connected to the inner outer wall of the bracket 1 61, the electric telescopic rod 2 92 is fixedly connected to the main shaft of the motor 3, and the blade 93 is fixedly connected to the end of the electric telescopic rod 2 92.

[0049] The cross-section of the blade 93 is circular to meet the requirements of rotary cutting of composite layers.

[0050] Example 1: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment, before the calcium silicon plate enters the composite layer pasting positioning device, the main motor 3 located on the base 1 starts to work, driving the main shaft of the rotating motor 4 on the conveying plate frame 2 to rotate, and driving the conveying roller 5 to start rotating. The number of the rotating motor 4 and the conveying roller 5 is multiple, so as to achieve a stable transportation effect of the calcium silicon plate on the conveying plate frame 2. The calcium silicon plate is continuously pushed forward by the rotating conveying roller 5, and its side first contacts with the scraper 79 fixedly connected to the end of the bracket 3 73. The scraper 79 is wedge-shaped on the side away from the bracket 3 73 and is made of silicone. It can scrape off excess glue on the edge of the calcium silicon plate so that it does not affect subsequent processing. At the same time, it also minimizes the friction on the edge of the calcium silicon plate. Then the calcium silicon plate contacts the roller 77 in the positioning assembly 7. Since the outer wall of the roller 77 is wrapped by a buffer layer 78, the buffer layer 78 is composed of an air bag, which can reduce the friction of the roller 7 7, thereby protecting the integrity of the calcium silicon board. At the same time, the bracket three 73 is subjected to the extrusion force from the calcium silicon board. Its shape is an eight-shaped shape with an opening facing the direction of entry of the calcium silicon board. Therefore, the bracket three 73 is subjected to the oblique thrust of the calcium silicon board and slides in the slide groove 72 of the bracket two 71. The bracket three 73 squeezes the sensor 74 through the spring 75. At the same time, the inner wall of the slide groove 72 also supports the sensor 74 to cause a reaction force on the spring 75. The sliding distance of the bracket three 73 depends on the width of the calcium silicon board, and due to the reaction force of the spring 75, the calcium silicon board is clamped between the two brackets 71, so that it can adapt to calcium silicon boards of different sizes. At the same time, most of the parts of the positioning component 7 that contact the calcium silicon board are the air bags in the buffer layer 78. Because the buffer layer 78 can be squeezed as the width of the calcium silicon board increases, it changes its shape to adapt to it, thereby minimizing the wear of the positioning component 7 on the calcium silicon board.

[0051] The sensor 74 is preferably a pressure sensor, which records the pressure changes applied by the spring 75 in real time. When the pressure increases to a certain value and no longer changes, it indicates that the head end of the calcium silicate board has completely passed through the positioning component 7 and arrived under the pasting component 6. At this time, the sensor 74 sends a signal to start the composite layer reel 62, composite layer guide roller 63 and heating roller 64 in the pasting component 6 to start working. The composite layer guide roller 63 rotates to transport the curled composite layer on the composite layer reel 62 to between the heating roller 64 and the calcium silicate board. The heating roller 64 presses the composite layer on the surface of the calcium silicate board base layer and solidifies the glue between the composite layer and the calcium silicate board by hot pressing, thereby making a wood veneer decorative board. The finished wood veneer board is then transported away from the pasting component 6 by the conveyor roller 5 for use in subsequent processing procedures; it solves the problem that the existing calcium silicate board composite layer pasting device can often only adapt to one size of calcium silicate board. For calcium silicate boards of different sizes, multiple product lines need to be established to paste the composite layers, which requires the purchase of additional machines, greatly increasing the production cost. The present invention reduces the production cost of the device and makes the device more widely applicable.

[0052] Example 2: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, in this embodiment, when the head end of the calcium silicate board passes through the positioning component 7, the bracket three 73 is pushed obliquely by the calcium silicate board and slides in the slide groove 72 of the bracket two 71. The bracket three 73 squeezes the sensor 74 through the spring 75. The sensor 74 records the pressure change given to it by the spring 75 in real time, and according to Hooke's law F (pressure magnitude) = k (spring constant) x (spring length change), since F (pressure magnitude) and k (spring constant) are known, x (spring length change) can be calculated, and the distances that the two brackets three 73 slide along the slide groove 72 can be obtained. The sum of the distances can be used to obtain the width of the calcium silicate board. According to this data, the electric telescopic rod one 82 in the centering component 8 is extended to a position that can just clamp the calcium silicate board, and then the rotating motor two 81 is started and drives the electric telescopic rod one 82 to drive the limit block 83 to start rotating, as shown in FIG. Figure 6 As shown, since the limit block 83 fixedly connected to the electric telescopic rod 82 is in the shape of a beveled cylinder, and there are two limit blocks 83 located on both sides of the calcium silicon plate, the inclined surface of the limit block 83 is continuously rotating, and the thicker part and the thinner part of the limit block 83 will alternately rotate to the side of the calcium silicon plate. When the calcium silicon plate is offset during translation, due to the continuous rotation of the limit block 83, its thinner part will give the calcium silicon plate a certain space for offset, thereby allowing the calcium silicon plate to have a slight offset at the beginning. As the limit block 83 rotates, its thicker part will slowly contact the calcium silicon plate, and the two limit blocks 83 will push the calcium silicon plate to the middle position, thereby offsetting the position offset of the calcium silicon plate. The traditional circular plate with straight sides clamps the calcium silicon plate, and the circular plate in this method always rubs the calcium silicon plate. The side of the calcium silicate board will be damaged, and the design of the oblique cut cylinder of the limit block 83 in the present invention can reduce the wear between itself and the side of the calcium silicate board, ensure the integrity of the calcium silicate board, and keep the calcium silicate board in the center position at all times, thereby achieving a stable centering effect on the calcium silicate board, so that the subsequent pasting component 6 can always paste the composite layer on the correct position of the calcium silicate board. At the same time, the cooperation of the centering component 8 and the positioning component 7 makes it applicable to calcium silicate board substrates of different sizes, greatly improving its applicability; it solves the problem that the existing calcium silicate board composite layer pasting device often requires manual alignment and pasting of the composite layer with the calcium silicate board, and the process inevitably causes the calcium silicate board to be positioned inaccurately due to manual operation errors, causing the composite layer to be crookedly pasted on the calcium silicate board, resulting in a decrease in the quality of the finished wood veneer, thereby significantly improving the quality of the wood veneer.

[0053] Example 3: Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, in the embodiment, when the pasting assembly 6 performs the pasting operation on the calcium silicate plate, the sensor 74 obtains the width of the calcium silicate plate through the steps in Embodiment 2, and the electric telescopic rod two 92 in the cutting assembly 9 is elongated according to the data, so that the distance between the two blades 93 fixedly connected to the two electric telescopic rod two 92 is exactly the width of the calcium silicate plate, at this time, the rotating motor three 91 drives the electric telescopic rod two 92 to rotate the blade 93, and cuts the composite layer coming out of the composite layer roller 62 into the same width as the calcium silicate plate, thereby further ensuring that the pasting assembly 6 can always paste the composite layer on the correct position of the calcium silicate plate, and the width of the composite layer is exactly matched with the width of the calcium silicate plate, thereby saving the step of cutting the edge of the wood veneer by the subsequent staff; as Figure 2 and 8 As shown, at the same time, since the support one 61 is fixedly connected with the electric telescopic rod three 10 on the outer wall, and the end of the electric telescopic rod three 10 is fixedly connected with the scraper two 11, the electric telescopic rod three 10 pushes the scraper two 11 to the two sides of the calcium silicate plate after the pasting operation is completed according to the width data of the calcium silicate plate provided by the sensor 74, and scrapes off the excess glue on the two sides of the calcium silicate plate due to the extrusion of the heating roller 64, so as to achieve the cleaning effect of the wood veneer product, save the step of manually cleaning the excess glue, improve the working efficiency of the device, solve the problem that the existing calcium silicate plate composite layer pasting device needs to manually cut off the excess part of the composite layer around the calcium silicate plate after the pasting of the composite layer is completed, the manual cutting consumes time and reduces the production efficiency, save the production time, and greatly improve the production efficiency.
