Description

Technical Field

[0001] The utility model relates to the technical field of double-track machines in composite board production equipment, and specifically relates to a height detection device and system for a double-track machine of composite boards. Background Technique

[0002] In the field of composite board production, it includes the production of various types of composite boards such as metal composite boards, color steel composite boards, and rock wool composite boards, involving a variety of technologies and equipment. These boards are welcomed by the market due to their excellent physical properties and wide range of uses, and are often used in multiple industries such as construction, packaging, and furniture manufacturing. Composite boards are usually formed by injecting polyurethane foam raw materials between two steel belts (or other substrates) and going through processes such as high-temperature foaming and curing. Its production line includes key equipment such as a decoiler, a preheating device, a foaming machine, a cloth feeder, a double-track machine, and a fixed-length cutting machine. The double-track machine has an upper and lower plate chain structure. Its working principle is to heat and apply a certain pressure to the sandwich board on the production line during the production process to ensure the bonding force of the board and assist and control the expansion of the foaming structure to ensure the best polymerization reaction, so as to ensure the thickness and flatness of the board during the conveying process. Due to the long length of the double-track production line, about 60 meters in length, the middle part may sag due to insufficient tension and its own gravity, and the connected track copper sleeves are worn for a long time. There will be a height difference between the upper track and the lower track along the length and width directions of the double-track machine, which will cause product quality problems.

[0003] In the prior art, the structure of the double-track composite board pressing device is as described in the Chinese utility model patent CN202623473U, which includes an upper track and a lower track with the same structure. According to the thickness of the produced composite board, the distance between the upper track and the lower track is adjusted through a hydraulic system. The height consistency of the double tracks and the flatness of the composite board are important factors affecting product quality. The height detection between the upper and lower tracks in the double-track machine is crucial for maintaining product quality. There is no height detection device for the upper and lower tracks of the double-track device in the prior art. Summary of the Utility Model

[0035] The data acquisition module 5 is also provided with a display screen for displaying the height difference and flatness calculated by the data acquisition module 5.

[0036] As Figure 5 shown, a height detection system for a composite board double crawler machine includes the detection device as described above, and also includes a control module and an automatic adjustment module. The control module and the automatic adjustment module are electrically connected to the power supply module 6. The control module is communicatively connected to the data acquisition module 5 of the detection device. The control module is also communicatively connected to the automatic adjustment module. The automatic adjustment module is used to control the lifting of the hydraulic system of the automatic adjustment module between the upper crawler belt 1 and the lower crawler belt 2.

[0037] Embodiment 2

[0038] Based on Embodiment 1, a further solution for the height detection device of a composite board double crawler machine is as follows.

[0039] As Figures 2 - 4 shown, the detection device further includes a fixed base 8 and an adjustment block 7. The fixed base 8 is detachably installed on the lower crawler belt 2. The displacement sensor 4 is installed on the adjustment block 7 through a sensor fixing block 3 and bolts. The adjustment block 7 is slidably connected to the fixed base 8 up and down for adjusting the height of the adjustment block 7 so as to adjust the height of the displacement sensor 4.

[0040] As Figure 4 shown, in order to achieve the up and down sliding connection between the adjustment block 7 and the fixed base 8, a vertical groove 10 is provided on one side surface of the fixed base 8, and a vertical convex block 9 is provided on the adjustment block 7. The convex block 9 cooperates with the groove 10.

[0041] In order to fix the adjusting block 7 to the fixed base 8, a long slot 11 is provided on the fixed base 8, and a threaded hole is provided on the adjusting block 7. The adjusting block 7 and the fixed base 8 are fixed by passing a bolt through the long slot 11 and the threaded hole.

[0043] In this embodiment, the displacement sensor 4 is a contact type laser displacement sensor. During operation, the stylus of the contact type laser displacement sensor contacts the upper track 1. When the upper track sinks, the stylus will contract synchronously with the upper track. When the upper track floats, the stylus will extend synchronously with the upper track.

The two detection devices are respectively arranged on both sides in the width direction between the upper track 1 and the lower track 2. The two detection devices make the measured data more accurate. By arranging this detection device on both sides in the width direction of the double-track machine, the height difference in the width direction between the upper and lower tracks can be detected to adjust the flatness in the width direction of a single track plate.

[0048] In addition to adjusting the height between the upper track 1 and the lower track 2 through the hydraulic system, the track copper sleeve at this position should also be replaced according to the position of the height difference.

[0049] The described control module is also connected to an alarm, which can be a buzzer or a signal lamp. When the processor detects that the height difference and flatness data exceed the threshold of the height difference preset by the comparator, an alarm signal is given through the alarm.

[0050] The circuit connections between the modules involved in Embodiment 1 and Embodiment 3 are prior art. Those skilled in the art can implement the technical solution according to the models of the modules and the circuit connections. The circuit connections do not fall within the scope of protection of this patent, and this patent will not describe them further.

[0051] According to the above embodiments, assuming that it is necessary to measure the height difference between the upper track 1 and the lower track 2 in the production of composite boards with a thickness of 150 mm, first, calibrate the initial value of the contact laser displacement sensor according to the 150-mm gauge block and set the reference measurement value. Then, fix the fixed base 8 of the detection device at one end in the length direction of the lower track 2 by a magnet and symmetrically arrange it on both sides in the width direction of the lower track 2. Next, start the double-track machine. The upper track 1 descends and contacts the induction head of the contact laser displacement sensor. As the upper and lower tracks move, according to the digital display amplifier of the digital acquisition module, the measured value can be displayed at any time on the display screen of the digital display amplifier or the touch display. According to the detection and use accuracy requirements, adjust the height between the two tracks at any time through the hydraulic system of the automatic adjustment module or manually replace the track copper sleeve, and provide real-time feedback for adjustment.

[0052] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
