[0039] The roller heating embossing machine can realize the production of various types of patterned belts 160 by replacing the embossing roller 120 with different patterns. However, during operation and when replacing the embossing roller 120 with different patterns, the staff may accidentally touch the heated embossing roller 120 and cause burns. To avoid such problems, please refer to Figure 1 The utility model provides a belt 160 surface embossing machine, including an embossing machine body 100, and also includes a protective mechanism, the protective mechanism includes a protective cover, the protective cover includes a shell 200 and a protective door 300 hinged on the shell 200, and the shell 200 is provided with a power-off protection component;
[0040] like Figure 1 and Figure 4 As shown, the power-off protection assembly includes a latch 320 fixedly mounted on the protective door 300, with a first reed 330 provided at the end of the latch 320, an assembly seat 230 provided on the housing 200, a pin hole 240 provided on the assembly seat 230, a second reed 250 and a third reed 260 symmetrically provided in the pin hole 240, and the latch 320 is driven to insert into the pin hole 240 so that the first reed 330 abuts against the second reed 250 and the third reed 260 respectively, thereby enabling the circuit of the embossing machine body 100 to pass.
[0041] like Figures 1 to 5 As shown, an iron sheet 310 is fixedly mounted on the protective door 300, and an electromagnet 220 corresponding to the position of the iron sheet 310 is fixedly mounted on the side of the housing 200 facing the protective door 300. When the circuit of the embossing machine body 100 is connected, the electromagnet 220 is energized to adsorb the patch, so that the protective door 300 is tightly closed. A push rod 280 is movably mounted on the bottom of the assembly seat 230, and one end of the push rod 280 extends to the inside of the pin hole 240 and is fixedly mounted with a movable block 270. The third spring 260 It is fixedly installed on the movable block 270, and a groove 241 adapted to the movable block 270 is opened on the inner wall of the pin hole 240. A return spring 290 is provided between the movable block 270 and the inner wall of the groove 241. Pressing the push rod 280 can drive the movable block 270 to move into the groove 241, so that the third reed 260 and the first reed 330 are misaligned, thereby disconnecting the circuit. The return spring 290 is used to drive the movable block 270 back to the pin hole 240 when the push rod 280 is released.
[0042] like Figure 3 As shown, the embossing machine body 100 is provided with a main shaft 110 and a movable shaft 140, one end of the main shaft 110 extends to the inner side of the shell 200 and is fixed with a printing roller 120 by bolts, and a limiting ring 130 is symmetrically provided on the main shaft 110 with respect to the printing roller 120, and a waist groove for accommodating the vertical movement of the movable shaft 140 is opened on the side wall of the embossing machine body 100, and an extrusion roller 150 adapted to the two limiting rings 130 is installed on the movable shaft 140, and the extrusion roller 150 moves vertically with the movable shaft 140, so that the belts 160 of different thicknesses remain in contact with the printing roller 120, thereby ensuring the engraving quality.
[0043] Specifically, when in use, the protective door 300 remains closed and the latch 320 is inserted into the pin hole 240. At this time, the first reed 330 abuts against the second reed 250 and the third reed 260 respectively, so that the circuit of the embossing machine body 100 is connected, and the embossing machine body 100 operates normally to engrave patterns on the belt 160. At the same time, the electromagnet 220 is energized to absorb the iron sheet 310, so that the protective door 300 is tightly closed. At this time, the protective cover and the protective door 300 wrap the printing roller 120 inside to prevent the staff from accidentally touching the printing roller 120 during the operation of the embossing machine body 100, causing burns or other injuries. When a pattern is engraved and the printing roller 120 needs to be replaced, the push rod 280 at the bottom of the protective cover can be pressed. The push rod 280 drives the movable block 270 to move into the groove 241, thereby separating the third reed 260 from the first reed 330. At this time, the circuit is broken, the embossing machine body 100 stops running, the electromagnet 220 is powered off and loses its magnetic force, and the protective door 300 can be opened to remove the limit ring 130 and replace the printing roller 120 with a different pattern.
[0044] Furthermore, if Figure 1 and Figure 3 As shown, a temperature detection device 400 is provided on the side of the limiting ring 130 facing the embossing roller 120, and a warning light 500 is fixedly mounted on the outer wall of the housing 200. The temperature detection device 400 and the warning light 500 are independently powered. The temperature detection device 400 can monitor the temperature of the embossing roller 120 in real time. When the temperature of the embossing roller 120 drops below the set index temperature, the warning light 500 lights up, indicating that the temperature of the embossing roller 120 will not burn the staff at this time and it can be replaced.
[0045] Leather material is not easy to shape at room temperature, so it needs to be heated to soften it so that the pattern can be engraved with the printing roller 120. When printing, the belt 160 is fed horizontally to the position of the printing roller 120. The current common roller heating embossing machine does not have a guiding facility after the belt 160 is embossed. The part of the belt 160 engraved by the printing roller 120 sags due to gravity, and forms an angle of nearly 90 degrees with the part that has not been engraved. Since the belt 160 is still in a high temperature state at this time, it is easy to cause the belt 160 to deform after being stretched, which in turn causes defects in the finished product.
[0046] To solve the above problems, Figure 1As shown, the belt 160 embossing machine of the present application is symmetrically provided with multiple groups of guide rollers 210 on the shell 200 along the traveling direction of the belt 160, so that the belt 160 can still travel a certain distance in the same horizontal direction after embossing, so that the belt 160 can be cooled and shaped, and the defect rate of the finished product can be reduced. The guide rollers 210 arranged at the inlet end of the belt 160 can guide the traveling direction of the belt 160, and prevent the belt 160 from tilting during the embossing process, resulting in skewed pattern engraving. At the same time, it also prolongs the distance between the staff's hands and the printing roller 120 when feeding the belt 160 to the printing roller 120, and avoids accidental touching of the printing roller 120 when feeding the belt 160, resulting in burns.
[0047] In order to reduce costs, the temperature detection device 400 in this application uses a temperature sensor. After years of development, the technology of temperature sensors has become mature, with a low failure rate, low price and easy installation and use.
[0048] Working principle: When replacing the printing roller 120, turn off the power of the embossing machine body 100, and stop the heating device of the heating printing roller 120. When the temperature sensor detects that the temperature of the printing roller 120 drops below the index temperature, the warning light 500 lights up, press the push rod 280 at the bottom of the protective cover, and the push rod 280 drives the movable block 270 to move into the groove 241, thereby disengaging the third reed 260 from the first reed 330, thereby breaking the circuit of the embossing machine body 100, and the embossing machine body 100 stops running. The electromagnet 220 is powered off and loses its magnetic force. The protective door 300 can be opened to remove the limit ring 130 and replace the printing roller 120 with a different pattern. After the replacement is completed, close the protective door 300, insert the pin 320 into the pin hole 240 of the assembly seat 230, so that the first reed 330 respectively abuts the second reed 250 and the third reed 260. At this time, the circuit of the embossing machine body 100 is connected, and the belt 160 can be embossed normally.
[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications may be made, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
