Description

Technical Field

[0001] The utility model relates to the technical field of sheet embossing, in particular to an embossing device and an artificial leather production system. The embossing device can be used for embossing artificial leather. Background Art

[0002] In many technical fields, sheets need to be embossed. For example, in the field of artificial leather, PVC artificial leather, TPO artificial leather, PU artificial leather, etc. used for automobile interior decoration all need to be embossed.

[0003] Specifically, the embossing process of the sheet material includes: first heating the surface of the sheet material, and then embossing the surface of the sheet material. Among them, the temperature of the sheet material surface will directly affect the color and pattern effect of the embossed product, so the heating temperature of the sheet material surface needs to be strictly controlled in the sheet material embossing process.

[0004] At present, three temperature sensors are mainly used to measure the temperature of the heated sheet. Specifically, the three temperature sensors are arranged in sequence along the horizontal direction of the sheet, so that the three temperature sensors measure the temperature of the left side, the middle and the right side of the sheet respectively, thereby roughly reflecting the temperature distribution of the sheet surface before embossing. Therefore, according to the temperature distribution of the sheet surface before embossing, the power of different heating templates on the heating device is adjusted to adjust the heating temperature of the sheet corresponding to the heating template to correct the temperature deviation.

[0005] However, the current temperature measurement scheme has low accuracy and cannot accurately measure the temperature distribution on the lateral surface of the entire sheet. This results in the inability to accurately adjust the power of different heating templates on the heating device when the temperature is abnormal. Multiple adjustments are required based on the experience of the staff, which affects the adjustment efficiency. Utility Model Content

[0006] The utility model aims to solve the problem of low accuracy in measuring the temperature distribution in the transverse direction of a sheet material. The utility model provides an embossing device which can accurately measure the temperature distribution in the transverse direction of a sheet material.

[0007] In order to solve the above technical problems, the embodiment of the utility model discloses an embossing device for embossing a sheet material, and the embossing device comprises:

[0012] A non-contact temperature sensor is arranged on one side of the heating device in a manner that is movable along the first direction. The non-contact temperature sensor is located above the auxiliary roller and is arranged toward the auxiliary roller. The non-contact temperature sensor is used to detect the temperature of the sheet passing through the auxiliary roller.

[0057] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0058] refer to Figure 1 and Figure 2The embodiment of the present application provides an embossing device 100 for embossing a sheet material 200. The embodiment of the present application does not limit the specific material of the sheet material 200. For example, in the embodiment of the present application, the sheet material 200 is artificial leather 210, but it is not limited thereto. The sheet material 200 can also be other materials, such as rubber. For ease of description, the embossing device 100 of the present application is described below using artificial leather 210 as an example.

[0059] In one possible implementation, continue to refer to Figure 1 and Figure 2 The embossing device 100 includes a conveying roller group 110, a heating device 120, an auxiliary roller 130, an embossing roller 140 and a non-contact temperature sensor 150. The auxiliary roller 130 and the embossing roller 140 both extend along the first direction X.

[0060] Exemplarily, the heating device 120 is disposed above the conveying roller group 110 along the vertical direction Z, the auxiliary roller 130 is disposed on one side of the conveying roller group 110 along the second direction Y (the second direction Y is perpendicular to the first direction X), and the embossing roller 140 is opposite to the auxiliary roller 130 and is spaced apart so that the artificial leather 210 passes between the embossing roller 140 and the auxiliary roller 130 to emboss the artificial leather 210. Exemplarily, along the second direction Y, the auxiliary roller 130 is located between the conveying roller group 110 and the embossing roller 140.

[0061] Specifically, the conveying roller group 110 is used to convey the artificial leather 210, the heating device 120 is used to heat the artificial leather 210 on the conveying roller group 110, and the auxiliary roller 130 is used to receive the heated artificial leather 210 so that the auxiliary roller 130 and the embossing roller 140 cooperate to emboss the artificial leather 210.

[0062] In other words, the conveying roller group 110 is used to convey the artificial leather 210 to between the auxiliary roller 130 and the embossing roller 140 so that the auxiliary roller 130 and the embossing roller 140 cooperate to emboss the artificial leather 210, and when the conveying roller group 110 conveys the artificial leather 210, the heating device 120 heats the artificial leather 210.

[0063] For example, in the embodiment of the present application, the first direction X is the transverse direction of the artificial leather 210, and the second direction Y is the length direction of the artificial leather 210. When the embossing device 100 is in operation, the artificial leather 210 moves along the second direction Y as a whole.

[0064] Further, continue to refer to Figure 1 and Figure 2The non-contact temperature sensor 150 is disposed on one side of the heating device 120 in a manner movable along the first direction X. The non-contact temperature sensor 150 is located above the auxiliary roller 130 and is disposed toward the auxiliary roller 130 to detect the temperature of the artificial leather 210 passing through the auxiliary roller 130.

[0065] refer to Figure 1 Combined with Figure 2 When the embossing device 100 is working, the non-contact temperature sensor 150 moves back and forth along the first direction X to detect the temperature of the artificial leather 210 before embossing in real time, and feeds back the temperature distribution of the artificial leather 210 along the first direction X to the system of the embossing device 100. Through the above scheme, the temperature distribution of the artificial leather 210 along the first direction X can be accurately detected, so that the staff can adjust the heating device 120 in time and accurately to prevent the heating temperature of a certain area of ​​the artificial leather 210 along the first direction X from being too high or too low, thereby reducing the scrap rate of the artificial leather 210. In addition, by adopting the above scheme, only one non-contact temperature sensor 150 needs to be set to detect the temperature of all areas of the artificial leather 210 along the first direction X, which effectively reduces the detection cost.

[0066] In some possible implementations, reference Figure 3 Combined with Figure 1 and Figure 2 The heating device 120 includes a plurality of heating lamp tubes 122. The specific number of the heating lamp tubes 122 is not limited in the embodiment of the present application. In the embodiment of the present application, four heating lamp tubes 122 are provided. In other possible embodiments, the number of the heating lamp tubes 122 may be five, six, seven or more.

[0067] Specifically, the heating device 120 includes heating lamps 122a, 122b, 122c and 122d spaced apart along the first direction X, and the heating lamps 122a, 122b, 122c and 122d all extend along the second direction Y.

[0068] Figure 3 In the figure, two adjacent dotted lines represent the heating range of a heating lamp tube 122. The heating lamp tube 122a heats the first area 211 of the artificial leather 210, the heating lamp tube 122b heats the second area 212 of the artificial leather 210, the heating lamp tube 122c heats the third area 213 of the artificial leather 210, and the heating lamp tube 122d heats the fourth area 214 of the artificial leather 210.

[0069] In the embodiment of the present application, the functions of the heating lamp tube 122a, the heating lamp tube 122b, the heating lamp tube 122c and the heating lamp tube 122d are the same. Here, the heating lamp tube 122a is taken as an example for description. By way of example, when the embossing device 100 is working, the non-contact temperature sensor 150 moves back and forth along the first direction X to detect the temperature of the artificial leather 210 located above the auxiliary roller 130. When the non-contact temperature sensor 150 detects that the temperature of the first area 211 of the artificial leather 210 is too high, the heating lamp tube 122a can be adjusted to reduce the heating power of the heating lamp tube 122a, thereby reducing the temperature of the first area 211 of the subsequent artificial leather 210. When the non-contact temperature sensor 150 detects that the temperature of the first area 211 of the artificial leather 210 is too low, the heating lamp tube 122a can be adjusted to increase the heating power of the heating lamp tube 122a, thereby increasing the temperature of the first area 211 of the subsequent artificial leather 210.

[0070] By adopting the above scheme, the non-contact temperature sensor 150 is moved back and forth along the first direction X to detect the temperature of the artificial leather 210 before embossing in real time, so that the temperature distribution of the artificial leather 210 along the first direction X can be accurately detected. The staff can adjust the heating power of each heating lamp 122 of the heating device 120 in a timely and accurate manner according to the temperature distribution of the artificial leather 210 along the first direction X to prevent the subsequent heating temperature of the artificial leather 210 from being too high or too low.

[0071] In some possible implementations, the system of the embossing device 100 can control the heating power of each heating lamp 122 of the heating device 120. Taking the heating lamp 122a as an example, when the non-contact temperature sensor 150 detects that the temperature of the first area 211 of the artificial leather 210 is too high, the system controls the heating power of the heating lamp 122a to be reduced, so that the temperature of the first area 211 of the subsequent artificial leather 210 is reduced. When the non-contact temperature sensor 150 detects that the temperature of the first area 211 of the artificial leather 210 is too low, the system controls the heating power of the heating lamp 122a to be increased, so that the temperature of the first area 211 of the subsequent artificial leather 210 is increased. By controlling the heating lamp 122 by the system, the subsequent heating temperature of different areas of the artificial leather 210 can be adjusted quickly and accurately according to the distribution of the artificial leather 210 along the first direction X, which can further reduce the scrap rate.

[0072] In some possible implementations, the system can also generate a temperature / position relationship diagram (eg, Figure 4 shown).

[0073] Specifically, refer to Figure 4 Combined with Figure 1 and Figure 2 , Figure 4 1 shows a temperature / position relationship diagram of the artificial leather 210 along the first direction X, wherein the ordinate represents the temperature of the artificial leather 210 detected by the non-contact temperature sensor 150. The abscissa represents the position of the artificial leather 210 along the first direction X. Specifically, Figure 4 The horizontal coordinate from -100 mm to 90 mm indicates that the length of the artificial leather 210 being measured along the first direction X is 190 mm. Figure 4 Point a indicates that the temperature of the artificial leather 210 5 mm to the right of the middle along the first direction X is 193°C.

[0074] For example, Figure 4 , the middle dotted line c represents the target temperature of the artificial leather 210, that is, the preset heating temperature of the artificial leather 210 by the heating device 120. The upper dotted line b represents the upper temperature limit of the artificial leather 210, and the bottom dotted line d represents the lower temperature limit of the artificial leather 210, wherein the upper temperature limit is higher than the target temperature, and the lower temperature limit is lower than the target temperature. When the actual temperature of the artificial leather 210 is lower than the upper temperature limit, and higher than the lower temperature limit, the temperature condition of the artificial leather 210 is normal. When the actual temperature of the artificial leather 210 is higher than the upper temperature limit, or lower than the lower temperature limit, the temperature condition of the artificial leather 210 is abnormal. Exemplarily, Figure 4 In the embodiment, the temperature conditions of all positions of the artificial leather 210 along the first direction X are normal.

[0075] The specific values ​​of the target temperature, the upper temperature limit and the lower temperature limit are not limited in the embodiments of the present application and can be set according to actual needs. For example, in the embodiments of the present application, the target temperature is 191°C, the upper temperature limit is 194°C, and the lower temperature limit is 188°C. In other possible embodiments, the target temperature can also be 192°C, 193°C, 194°C, etc., the upper temperature limit can also be 195°C, 197°C, 200°C, etc., and the lower temperature limit can also be 187°C, 185°C, 180°C, etc.

[0076] For example, when the non-contact temperature sensor 150 detects that the temperature of the first area 211 (not limited to this, it can also be any one of the second area 212, the third area 213 or the fourth area 214, and the first area 211 is used as an example here) of the artificial leather 210 along the first direction X is abnormal or the temperature fluctuates greatly, the non-contact temperature sensor 150 can be controlled to move to the first area 211, and the temperature of the first area 211 is monitored at a fixed point, and the real-time temperature of the first area 211 is fed back to the system. The system can generate a real-time temperature map of the first area 211 according to the real-time temperature fed back by the non-contact temperature sensor 150 (such as Figure 5 shown).

[0077] Specifically, refer to Figure 5 Combined with Figure 1 and Figure 2 , Figure 5 2 shows a real-time temperature diagram of a first area 211 of an artificial leather 210 along a first direction X, wherein: Figure 5 The ordinate represents the real-time temperature of the artificial leather 210, and the abscissa represents the measurement time (in seconds, but not limited thereto, in other possible implementations, the unit may also be minutes or other time units). For example, Figure 5 Point e indicates that the non-contact temperature sensor 150 detects that the temperature of the first area 211 of the artificial leather 210 is 193° C. at the 12th second.

[0078] The upper dotted line f represents the upper temperature limit of the artificial leather 210, the middle dotted line g represents the target temperature of the artificial leather 210, and the bottom dotted line h represents the lower temperature limit of the artificial leather 210. Figure 5 The target temperature, upper temperature limit and lower temperature limit in Figure 4 The target temperature, upper temperature limit and lower temperature limit in are the same and will not be described again here.

[0079] When the non-contact temperature sensor 150 detects that the temperature of the first area 211 of the artificial leather 210 is lower than the upper temperature limit and higher than the lower temperature limit, the temperature of the first area 211 of the artificial leather 210 is normal. When the non-contact temperature sensor 150 detects that the temperature of the artificial leather 210 is higher than the upper temperature limit or lower than the lower temperature limit, the temperature of the first area 211 of the artificial leather 210 is abnormal. Figure 5 In the example, the temperature of the first area 211 of the artificial leather 210 is measured to be normal.

[0080] In addition, the staff can also verify the difference between the heating temperature set by the heating lamp 122 and the actual heating temperature according to the real-time temperature graph. Figure 5 and Figure 3 Taking the heating lamp 122a and the first area 211 of the artificial leather 210 as an example, after the staff sets the heating temperature of the heating lamp 122a to 191°C, the staff can control the non-contact temperature sensor 150 to move to the first area 211, and detect the real-time temperature of the first area 211 of the artificial leather 210 through the real-time temperature map of the first area 211, so as to verify the difference between the heating temperature set by the heating lamp 122a and the actual heating temperature, so as to facilitate the subsequent optimization of the set temperature of the heating lamp 122a.

[0081] In some possible implementations, continue to refer to Figure 1 and Figure 2, the embossing roller 140 is movable relative to the auxiliary roller 130. Specifically, the embossing roller 140 and the auxiliary roller 130 have a first spacing and a second spacing, and the first spacing is greater than the second spacing. When loading, the embossing roller 140 is first moved to the first spacing in a direction away from the auxiliary roller 130, the artificial leather 210 is installed on the embossing device 100, and a part of the artificial leather 210 passes between the embossing roller 140 and the auxiliary roller 130, and then the embossing roller 140 is moved to the auxiliary roller 130 to the second spacing, so that the embossing roller 140 and the auxiliary roller 130 jointly squeeze the artificial leather 210 and emboss the artificial leather 210.

[0082] In some possible implementations, continue to refer to Figure 1 and Figure 2 The embossing device 100 further includes a fixing part 151 and a moving part 152 .

[0083] Exemplarily, the fixing portion 151 is disposed at one side of the heating device 120, the fixing portion 151 extends along the first direction X, and the moving portion 152 is connected to the fixing portion 151 in a movable manner along the first direction X. The non-contact temperature sensor 150 is fixed to the moving portion 152. Thus, the non-contact temperature sensor 150 can move relative to the artificial leather 210 along the first direction X.

[0084] The specific position of the fixing portion 151 is not limited in the embodiment of the present application, as long as the non-contact temperature sensor 150 can detect the temperature of the artificial leather 210 after the artificial leather 210 is heated by the heating device 120 and before the artificial leather 210 is embossed. For example, in the embodiment of the present application, the heating device 120 further includes a housing 121, and the fixing portion 151 is fixed to the housing 121.

[0085] The embodiment of the present application does not limit the specific types of the fixing portion 151 and the moving portion 152, as long as the non-contact temperature sensor 150 can be moved relative to the artificial leather 210 along the first direction X. For example, in the embodiment of the present application, the fixing portion 151 is a slide rail 1511, and the moving portion 152 is a slider 1521, and the slider 1521 is connected to the slide rail 1511 in a slidable manner along the first direction X, and the non-contact temperature sensor 150 is fixed on the slider 1521, so that the non-contact temperature sensor 150 can move relative to the artificial leather 210 along the first direction X.

[0086] In some other possible implementations, the fixed portion 151 may also be a screw, the movable portion 152 may be a screw nut, the screw nut is connected to the screw in a manner movable along the first direction X, and the non-contact temperature sensor 150 is fixed to the screw nut.
