Description

[0002] Surface gluing is a common processing mode of boards. In order to improve the efficiency, most artificial board factories use double-sided gluing machines for production, and the gluing amount of glue plays a very key role in the gluing of artificial boards, therefore, accurate control of the gluing amount is particularly important and is an important part of quality control.

[0003] At present, the gluing amount is measured by the following method: the board before gluing is placed on an electronic scale for weighing, then the board is placed on a double-sided gluing machine for gluing, and after gluing, the board is placed on the scale again for weighing, and the gluing amount is calculated according to the difference between the front and rear weights of the board.

[0004] The above method assumes that the gluing amount of the upper board and the gluing amount of the lower board are consistent, but the distance between the corresponding adjusting roller and the rubber roller of the upper gluing layer and the distance between the corresponding adjusting roller and the rubber roller of the lower gluing layer are both adjusted by manual visual adjustment, and there is actually a certain difference, and the distance between the upper and lower rubber rollers also affects the actual gluing amount, therefore, the gluing amounts of the upper and lower gluing surfaces cannot be completely consistent, which leads to low accuracy of the measured values of the gluing amounts of the upper and lower boards, and leads to low product quality of the boards.

DETAILED DESCRIPTION

[0041] In order to enable persons skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should fall within the scope of protection of the present application.

[0042] Since the accuracy of the glue application measurement value of the double-sided gluing machine for plates is low in some technologies, the product quality of the plates is low. In order to solve the technical problem, the present application provides a double-sided gluing machine for plates capable of automatically measuring the glue application, and the structures of each part of the double-sided gluing machine for plates capable of automatically measuring the glue application will be described below.

[0043] For example, in order to improve efficiency, most of the current artificial board factories use double-sided gluing machines for production. The glue application plays a very key role in the gluing of artificial boards, therefore, accurate control of the glue application is particularly important, and is an important part of plate quality control. When using a double-sided gluing machine to produce plywood, the current double-sided gluing machine technology has the problem of being unable to accurately measure the glue application of the upper and lower coated plates.

[0044] At present, the amount of glue is measured by the following method: first, the board before gluing is weighed on an electronic scale by hand, then it is put into a double-sided gluing machine for gluing, and then the board is weighed again on the scale after gluing, and the amount of glue on the board is calculated by the difference between the two weights divided by the area and then divided by 2 (two gluing surfaces). The above method essentially assumes that the amount of glue on the upper and lower boards is consistent, but in fact, the amount of glue on the upper and lower gluing surfaces of the board cannot be completely consistent due to factors such as the difference in roller spacing. Therefore, it is particularly important to monitor the difference in the amount of glue on the upper and lower boards, and precise control of the amount of glue on the upper and lower boards is beneficial to improving product quality.

[0045] As shown in Figure 1 , it is a structural schematic diagram of a double-sided gluing machine for boards provided by the present application, which can automatically measure the amount of glue in an embodiment.

[0046] In view of the above problems, the present application provides a double-sided gluing machine for boards which can automatically measure the amount of glue, comprising:

[0047] The first rubber roller 11 and the second rubber roller 12 are arranged in the first support 1; a setting space for the board to be glued 13 is arranged between the first rubber roller 11 and the second rubber roller 12; the board to be glued 13 is transported to the gap between the first rubber roller 11 and the second rubber roller 12, i.e. the setting space, through the guide rails, i.e. the first guide rail 25 and the second guide rail 35, arranged by the second support 2 and the third support 3, and the glue on the first rubber roller 11 is applied to the first surface of the board to be glued 13, and the glue on the second rubber roller 12 is applied to the second surface of the board to be glued 13, thereby completing the gluing work of the board.

[0048] As shown in Figure 4 , it is a structural schematic diagram of the second support 2 in the present application.

[0049] The first guide rail 25 is arranged on the side of the second support 2 close to the board to be glued 13, and the first guide rail 25 is used for transporting the board to be glued 13, wherein the first guide rail 25 can be arranged in a way that an external device provides power for it to transport the board to be glued 13; the board to be glued 13 can also be transported by other power equipment, and the first guide rail 25 serves as a device to assist the transportation of the board to be glued 13.

[0050] As shown in Figure 5 , it is a structural schematic diagram of the third support 3 in the present application.

[0051] The third support 3 is provided with a second guide rail 35 near one side of the plate to be glued 13, and the second guide rail 35 is used for transporting the plate to be glued 13. The second guide rail 35 can be provided with an external power device to provide power for the plate to be glued 13 to be transported. The plate to be glued 13 can also be transported by other power devices, and the second guide rail 35 serves as a device for assisting the plate to be glued 13 to be transported.

[0052] The first adjusting roller 21 and the first feeding module 22 are arranged in the second support 2. The second support 2 is arranged on one side of the first support 1, and the second support 2 is perpendicular to the first support 1. The first adjusting roller 21 is in the same horizontal direction as the first rubber roller 11. The first feeding module 22 is arranged on the top of the second support 2 and located in the first space between the first adjusting roller 21 and the first rubber roller 11. The glue filled in the first feeding module 22 falls into the first space through the feeding port. The second adjusting roller 31 and the second feeding module 32 are arranged in the third support 3. The third support 3 is arranged on the other side of the first support 1, and the third support 3 is perpendicular to the first support 1. The second adjusting roller 31 is in the same horizontal direction as the second rubber roller 12. The second feeding module 32 is arranged on the top of the third support 3 and located in the second space between the second adjusting roller 31 and the second rubber roller 12. The glue filled in the second feeding module 32 falls into the second space through the feeding port.

[0053] For example, in the feeding module of the plate double-sided gluing machine, an automatic feeding system of a set of upper gluing machine (first feeding module 22) and lower gluing machine (second feeding module 32) is added respectively. The glue setting mass value m 1上 and m 1下 (10Kg for example) can be set, and the valve (such as electromagnetic valve) can be opened to automatically discharge glue. When the set discharge value is reached, the valve (electromagnetic valve) is automatically closed. For example, a liquid level switch is arranged in the first space and the second space. When the glue in the first space or the second space is lower than the detection head of the liquid level switch, the valve is opened to fill the glue in the first space or the second space to the preset height. The height of the liquid level switch is greater than the height of the first liquid level sensor and the second liquid level sensor.

[0054] The glue application amount for artificial board is generally in the range of 120-300g / m 2The glue amount is in a range that allows the distance between the rubber roller of the glue spreader and the adjusting roller of the glue spreader to be small enough, so that the glue from the feeding module enters the closed glue groove space formed by the rubber roller of the glue spreader, the adjusting roller of the glue spreader and the two side baffles of the glue spreader (the viscosity of the woodworking glue is relatively large, and the viscosity under the condition of 25°C / 30 rpm is generally ≥3000 cP), causing the glue with large viscosity to not overflow from the gap between the adjusting roller and the rubber roller when the glue from the feeding module is located in the first space and the second space.

[0055] It is worth noting that the first adjusting roller 21 and the second adjusting roller 31 are rotatably arranged in the plate glue spreader, and the glue is filled into the space between the rubber roller and the adjusting roller. It can be understood that, due to the viscosity of the glue, if the first adjusting roller 21 or the second adjusting roller 31 does not rotate or displace for a long time, the glue will be adhered to the first adjusting roller 21 or the second adjusting roller 31, causing the rubber roller to be adhered to the glue, and thus the glue spreading work cannot be performed. Therefore, to prevent the above problem, the first adjusting roller 21 and the second adjusting roller 31 are rotatably arranged in the plate glue spreader, and an external motor is provided to drive the first adjusting roller 21 and the second adjusting roller 31.

[0056] The first liquid level sensor is arranged in the first space, and the second liquid level sensor is arranged in the second space. The liquid level sensor is used to obtain the liquid level height of the glue in the first space and the second space. When the liquid level height of the glue in the first space and the second space is less than the height of the liquid level sensor, a glue amount calculation request is sent to the controller. Before the liquid level sensor is installed, the glue mass m 2上 and m 2下 , i.e., the glue amount below the height of the first liquid level sensor detection probe in the first space and the glue amount below the height of the second liquid level sensor detection probe in the second space (the glue variety is unchanged, and the mass is usually a constant value).

[0057] The double-sided rubber coating machine capable of automatically measuring the rubber coating amount of the plate further comprises a support rod 4 arranged in the horizontal direction on the first support 1, one end of the support rod 4 is connected with the first support 1, and the other end extends away from the first support 1; the support rod 4 is used for mounting the laser emitter 5; the laser emitter 5 is arranged on the side of the support rod 4 away from the first support 1; the laser emitter 5 is configured to obtain the quantity of the plate to be coated with rubber 13. The laser projection direction of the laser emitter 5 is the vertical direction, and the laser is projected in the direction where the third support 3 is located, wherein the setting position of the laser emitter 5 is based on the condition that the laser projected by the laser emitter 5 is not blocked by the rubber roller. The laser emitter 5 obtains the quantity of the plate to be coated with rubber 13 entering the gap between the rubber rollers by projecting the laser, so as to prepare for subsequent calculation of the rubber coating amount of the plate to be coated with rubber 13.

[0058] The controller electrically connected with the first liquid level sensor and the second liquid level sensor is configured to obtain the rubber coating amount of the surface of the plate to be coated with rubber 13 according to the glue height obtained by the first liquid level sensor and the second liquid level sensor. The controller is used for obtaining the quantity of the plate to be coated with rubber 13 which is completed with coating according to the mass of the rubber coating in the first feeding module 22, the mass of the rubber coating below the height of the detection probe of the first liquid level sensor in the first space, the mass of the rubber coating in the second feeding module 32, the mass of the rubber coating below the height of the detection probe of the second liquid level sensor in the second space, the length and the width of the plate to be coated with rubber 13, and responding to the rubber coating amount calculation request of the first liquid level sensor and the second liquid level sensor, the rubber coating amount of the first surface and the second surface of the plate to be coated with rubber 13 can be calculated through the above data. Wherein, the rubber coating amount of the first surface and the second surface of the plate to be coated with rubber 13 is obtained by the following formula:

[0059] The average rubber coating amount of the first surface of the plate to be coated with rubber 13 is:

[0060] P 上 =(m 1上 -m 2上 )÷(n×a×b);

[0061] In the formula, m 1上 is the mass of the rubber coating in the first feeding module 22; m 2上 is the mass of the rubber coating below the height of the detection probe of the first liquid level sensor in the first space; n is the quantity of the plate to be coated with rubber 13 which is completed with coating; a is the length of the plate to be coated with rubber 13; and b is the width of the plate to be coated with rubber 13.

[0062] The average rubber coating amount of the second surface of the plate to be coated with rubber 13 is:

[0063] P 下 =(m1下 -m 2下 ) ÷ (n × a × b) ;

[0064] In the formula, m 1下 is the amount of glue in the second feeding module 32; m 2下 is the amount of glue below the detection probe of the second liquid level sensor in the second space.

[0065] It can be understood that the amount of glue on the completed board is obtained from the filling of the glue to the completion of the spraying of the feeding module, wherein the amount of glue below the detection probe of the liquid level sensor in the closed glue tank space, i.e. m 1下 and m 2下 , further improves the calculation accuracy of the amount of glue on the board to be glued 13, and the average amount of glue on one side of the board to be glued 13 is obtained by the total amount of glue, the amount of glue below the detection probe of the liquid level sensor in the closed glue tank space, the number of completed boards, and the area of the board to be glued.

[0066] It is worth noting that the number n of the completed board to be glued 13 is generally an integer value, and in actual calculation, the value of n may not completely cover one side of the board with glue, but it is recorded in the value of n. However, the value of n is usually large, usually n > 10, that is, the glue in the feeding module can complete the gluing work of a large number of boards, so the influence on the final calculation result of the amount of glue is very small and can be ignored.

[0067] As shown in Figure 2 , it is a structural schematic diagram of a double-sided gluing machine for boards capable of automatically measuring the amount of glue provided by the present application in another embodiment.

[0068] The double-sided gluing machine for boards capable of automatically measuring the amount of glue further comprises:

[0069] The first baffle 6 is arranged at the gap between the first rubber roller 11 and the first adjusting roller 21 and on both sides of the first rubber roller 11 and the first adjusting roller 21; the first baffle 6 and the first rubber roller 11 and the first adjusting roller 21 form the first space; the second baffle 7 is arranged at the gap between the second rubber roller 12 and the second adjusting roller 31 and on both sides of the second rubber roller 12 and the second adjusting roller 31; the second baffle 7 and the second rubber roller 12 and the second adjusting roller 31 form the second space. The first baffle 6 arranged on both sides of the gap between the first rubber roller 11 and the first adjusting roller 21 can form the first space between the first baffle 6 and the first rubber roller 11 and the first adjusting roller 21, so as to prevent the glue in the first space from overflowing from the gap between the first rubber roller 11 and the first adjusting roller 21; the second baffle 7 arranged on both sides of the gap between the second rubber roller 12 and the second adjusting roller 31 can form the second space between the second baffle 7 and the second rubber roller 12 and the second adjusting roller 31, so as to prevent the glue in the second space from overflowing from the gap between the second rubber roller 12 and the second adjusting roller 31.

[0070] As shown in Figure 3 , it is a structure diagram of the first baffle 6 and the second baffle 7 in the application.

[0071] In this embodiment, the cross section of the first baffle 6 and the second baffle 7 has a first edge and a second edge parallel to each other, the length of the first edge is greater than that of the second edge; further comprising a third edge and a fourth edge with the same shape; the first edge, the third edge, the second edge and the fourth edge are connected in sequence to form the cross section; the third edge and the fourth edge are curves. By arranging the two opposite surfaces of the first baffle 6 and the second baffle 7 as curved surfaces corresponding to the third edge and the fourth edge of the cross section of the first baffle 6 and the second baffle 7, the third edge and the fourth edge are quarter circles, through the above structure, the curved surface part of the first baffle 6 and the second baffle 7 corresponding to the third edge and the fourth edge can be clamped between the rubber roller and the adjusting roller, wherein the first baffle 6 and the second baffle 7 are clamped on the outer side of the rubber roller and the adjusting roller, without affecting the rotation of the rubber roller and the adjusting roller. Through the structure of the first baffle 6 and the second baffle 7, the installation efficiency of the baffle can be improved.

[0072] In the embodiment, the first baffle 6 and the second baffle 7 are provided with connecting holes 61; the first liquid level sensor and the second liquid level sensor are arranged in the connecting holes 61. By arranging the connecting holes 61, the first liquid level sensor and the second liquid level sensor can be clamped in the connecting holes 61, so that the installation efficiency of the liquid level sensor can be improved.

The motor 81 is controlled to rotate the power shaft arranged on the motor 81, so as to drive the adjusting shaft 82, the first rubber roller 11 and the second rubber roller 12 to rotate through the transmission belt 9, thereby completing the rubber coating work of the plate to be coated 13.

[0074] In the embodiment, the first rubber roller 11 is slidingly connected in a first sliding groove 14 arranged on the first support 1; the adjusting shaft 82 is slidingly connected in a second sliding groove 83 arranged on the fourth support 8. The rubber coating amount of the plate to be coated 13 is affected by the distance between the adjusting roller and the rubber roller, and the distance between the two rubber rollers. The distance between the first rubber roller 11 and the second rubber roller 12 can be changed by adjusting the position of the first rubber roller 11 in the first sliding groove 14. When the position of the first rubber roller 11 in the first sliding groove 14 changes, the position of the adjusting shaft 82 in the second sliding groove 83 will also change, thereby completing the adjustment of the distance between the first rubber roller 11 and the second rubber roller 12. Compared with the fixed arrangement of the distance between the first rubber roller 11 and the second rubber roller 12, the above structure can flexibly adjust the rubber coating amount of the plate to be coated 13.

[0075] In the embodiment, the first adjusting roller 21 is rotationally connected in the first sliding block 23 arranged in the second support 2; the first adjusting screw 24 is arranged in the second support 2, one end of the first adjusting screw 24 is connected with the first sliding block 23, and the other end extends to the side away from the first support 1 through the second support 2; wherein the distance between the first rubber roller 11 and the first adjusting roller 21 is adjusted by the first adjusting screw 24. The glue coating amount of the plate material 13 to be coated is affected by the distance between the adjusting roller and the rubber roller, and the distance between the two rubber rollers. Among them, the distance between the first adjusting roller 21 and the first rubber roller 11 can be adjusted by the first adjusting screw 24; compared with the fixed arrangement of the distance between the first rubber roller 11 and the first adjusting roller 21, the above structure can make the plate double-sided coating machine flexibly adjust the glue coating amount of the plate material 13 to be coated.

[0076] In the embodiment, the second adjusting roller 31 is rotationally connected in the second sliding block 33 arranged in the third support 3; the second adjusting screw 34 is arranged in the third support 3, one end of the second adjusting screw 34 is connected with the second sliding block 33, and the other end extends to the side away from the first support 1 through the third support 3; wherein the distance between the second rubber roller 12 and the second adjusting roller 31 is adjusted by the second adjusting screw 34. The glue coating amount of the plate material 13 to be coated is affected by the distance between the adjusting roller and the rubber roller, and the distance between the two rubber rollers. Among them, the distance between the second adjusting roller 31 and the second rubber roller 12 can be adjusted by the second adjusting screw 34; compared with the fixed arrangement of the distance between the second rubber roller 12 and the second adjusting roller 31, the above structure can make the plate double-sided coating machine flexibly adjust the glue coating amount of the plate material 13 to be coated.

The rubber coating amount of one side of the to-be-coated plate 13 can be obtained by the total rubber coating amount, the rubber coating amount below the height of the detection probe of the liquid level sensor in the closed glue tank space, the number of completed coated plates, and the plate area of the coated plate. Through long-term coating work of the double-sided plate coating machine, the corresponding relationship between the distance between the two rubber rollers and the distance between the rubber roller and the adjusting roller corresponding to different rubber coating amounts can be obtained.
