Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a laminating machine with roller spacing measurement function. Background Technology

[0002] TPU leather is a commonly used automotive interior material in the current technology.

[0003] The existing TPU leather includes a base film and a face film. The base film and face film are respectively wound around the sizing roller and the embossing roller of the laminating machine, and then glued and pressed together through the gap between the sizing roller and the embossing roller to form TPU leather.

[0004] If the gap between the sizing roller and the embossing roller is too large, the TPU leather after lamination will delaminate and peel due to insufficient pressure applied during lamination.

[0005] Therefore, the gap between the sizing roller and the embossing roller needs to be checked before each start-up to ensure the bonding quality of the TPU leather.

[0006] Current technology involves manually using feeler gauges to check the gap between the sizing roller and the embossing roller, which is prone to large human errors, time-consuming, and inefficient. Utility Model Content

[0007] To address the aforementioned shortcomings, the purpose of this invention is to propose a laminating machine with a roller gap measurement function, thereby solving the problems of large human error, long time, and low work efficiency caused by manually using feeler gauges to measure roller gaps.

[0008] To achieve this objective, the present invention adopts the following technical solution: A laminating machine with roller spacing measurement function includes a sizing roller, an embossing roller and a displacement sensor; The embossing roller and the sizing roller are arranged vertically opposite each other; the embossing roller has an adjustable mounting structure to adjust the distance between the circumferential surface of the embossing roller and the circumferential surface of the sizing roller. The sizing roller is equipped with a first bearing seat at both its left and right ends; the embossing roller is equipped with a second bearing seat at both its left and right ends. The displacement sensor includes two signal transmitters; the signal transmitters are mounted on the second bearing housing, with the transmitting end of the signal transmitter facing downwards and aligned with the top surface of the corresponding first bearing housing; the displacement sensor outputs a distance signal between the transmitting end of the signal transmitter and the top surface of the first bearing housing.

[0009] Furthermore, it also includes at least two lifting cylinders; The two lifting cylinders are respectively mounted on the machine base of the bonding machine; the output end of the lifting cylinder extends downward and is connected to the top surface of the corresponding second bearing seat.

[0010] Furthermore, it also includes signal converters and displays; The displacement sensor is connected to the signal converter, and the signal converter is also connected to the display.

[0011] Furthermore, it also includes a sizing plate; The sizing disc is installed below the sizing roller, and the sizing disc is equipped with glue nozzles.

[0012] Preferably, the displacement sensor is a laser displacement sensor. The beneficial effects of the technical solution of this utility model are as follows: The laminating machine of this utility model with roller spacing measurement function can detect the roller spacing between the embossing roller and the sizing roller through a displacement sensor. It is simple to operate, fast, and has high working efficiency. Attached Figure Description

[0014] The following is in conjunction with the appendix Figure 1 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0015] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] A laminating machine with roller spacing measurement function includes a sizing roller 1, an embossing roller 3 and a displacement sensor 5; The embossing roller 3 and the sizing roller 1 are arranged vertically opposite each other; the embossing roller 3 has an adjustable mounting structure to adjust the distance between the circumferential surface of the embossing roller 3 and the circumferential surface of the sizing roller 1. The left and right ends of the sizing roller 1 are each equipped with a first bearing seat 11; the left and right ends of the embossing roller 3 are each equipped with a second bearing seat 31. The displacement sensor 5 includes two signal transmitters 51; the signal transmitters 51 are mounted on the second bearing seat 31, with the transmitting end of the signal transmitter 51 facing downward and aligned with the top surface of the corresponding first bearing seat 11, and the displacement sensor 5 outputs a distance signal between the transmitting end of the signal transmitter 51 and the top surface of the first bearing seat 11.

[0018] The existing technology involves manually measuring the gap between the embossing roller 3 and the sizing roller 1 using a feeler gauge.

[0019] like Figure 1 As shown, when the displacement sensor 5 is turned on, the transmitting ends of the two signal transmitters 51 send signals to the top surface of the corresponding first bearing seat 11 respectively. The displacement sensor 5 outputs the reflected signals received by the two signal transmitters 51, thereby obtaining the average distance X0 between the two transmitting ends of the signal transmitters 51 and the top surface of the corresponding first bearing seat 11. At the same time, using a detection tool, the distance between the circumferential surface of the embossing roller 3 and the circumferential surface of the sizing roller 1 at different points is measured to obtain the average distance Y0, and the constant K is set to X0-Y0.

[0020] When the laminating machine is started, as the embossing roller 3 rises or falls, the distance between the transmitting end of the signal transmitter 51 and the top surface of the corresponding first bearing seat 11 changes accordingly, and the change is the same as the change in distance between the circumferential surfaces of the embossing roller 3 and the circumferential surfaces of the sizing roller 1. If the average distance between the two transmitting ends of the signal transmitter 51 and the top surface of the corresponding first bearing seat 11 is X1, then the average inter-roller distance Y1 between the corresponding embossing roller 3 and the sizing roller 1 is Y1 = X1 - K. Therefore, by using the average distance X1 between the two transmitting ends and the top surface of the corresponding first bearing seat 11 detected in real time by the displacement sensor 5, and using the formula Y1 = X1 - K, the average inter-roller distance Y1 representing the embossing roller 3 and the sizing roller 1 can be calculated and obtained. Compared with the prior art, obtaining the above average inter-roller distance Y1 by using the displacement sensor 5 is simple to operate and has high working efficiency.

[0021] Furthermore, it also includes at least two lifting cylinders 4; The two lifting cylinders 4 are respectively mounted on the machine base of the bonding machine; the output end of the lifting cylinder 4 extends downward and is connected to the top surface of the corresponding second bearing seat 31.

[0022] like Figure 1 As shown, the forming thickness of the material to be bonded can be adjusted by simultaneously raising and lowering the two second bearing seats 31 using two lifting cylinders 4, thereby adjusting the distance between the circumferential surface of the embossing roller 3 and the circumferential surface of the sizing roller 1.

[0023] Furthermore, it also includes a signal converter 6 and a display 7; The displacement sensor 5 is connected to the signal converter 6, and the signal converter 6 is also connected to the display 7.

[0024] like Figure 1 As shown, the distance between the circumferential surface of the embossing roller 3 and the circumferential surface of the sizing roller 1, as measured by the displacement sensor 5, can be displayed on the display 7, and the corresponding threshold can be set on the display 7.

[0025] When the laminating machine is running, if the distance between the circumferential surface of the embossing roller 3 and the circumferential surface of the sizing roller 1 exceeds the set threshold, the display 7 will issue an alarm signal so that the operator can adjust the distance between the embossing roller 3 and the sizing roller 1 in time by lifting the cylinder 4 after receiving the alarm, thereby reducing the output of defective products.

[0026] Furthermore, it also includes a sizing plate 2; The sizing disc 2 is installed below the sizing roller 1, and the sizing disc 2 is equipped with glue nozzles.

[0027] like Figure 1 As shown, the base film wound on the sizing roller 1 first passes through the sizing disc 2, and the glue sprayed by the glue nozzle is applied to the surface of the base film. The base film rotates with the sizing roller 1 and reaches between the embossing roller 3 and the sizing roller 1, and then is bonded to the surface film wound on the embossing roller 3 to form a composite film 8.

[0028] Preferably, the displacement sensor 5 is a laser displacement sensor.

[0029] Laser displacement sensors are non-contact displacement sensors with advantages such as small size and high detection accuracy.

[0030] Some composite films 8 have a thickness of only 15-60μm. If the gap between the embossing roller 3 and the sizing roller 1 exceeds 5% of the thickness of the composite film 8, i.e. 0.75-3μm, the output composite film 8 will have quality defects due to insufficient bonding pressure. Since the gap value range is small and the detection accuracy requirement is high, the displacement sensor 5 is preferably a laser displacement sensor.

[0031] In summary, such as Figure 1 The embodiment of the present invention shown herein describes a laminating machine with roller spacing measurement function, which can detect the roller spacing between the embossing roller 3 and the sizing roller 1 through the displacement sensor 5. It has the advantages of simple operation and high work efficiency.

[0032] The laminating machine with roller spacing measurement function described in this utility model can also effectively solve the problems of uneven sizing on the surface, weak bonding, and prevent abnormalities such as wrinkles and cracks in the post-processing surface molding. It can also prevent human error and effectively play a role in preventing mistakes.

[0033] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
