[0048] At present, in the transmission type heating equipment, a heating roller is usually used to heat the product passing through the roller surface of the heating roller so that the product can meet the corresponding process requirements. The heating roller in the traditional technology usually has an inner cavity inside the heating roller, and then the heat is transferred to the roller surface of the heating roller through the action of heat transfer oil, thereby heating the product; however, the heating method of heating oil has a relatively complex internal structure of the heating roller, and it takes a long time to reach the preset requirements. For example, it generally takes about 1 hour to heat up to 100℃, which is inconvenient in application.
[0049] In view of the above technical problems, the present embodiment mainly provides a heating roller and a heating device thereof, which can have a higher heating response efficiency and a better application effect.
[0050] like Figure 1-3As shown in , a heating roller provided in some embodiments of the present application includes a heat-conducting cylinder 1 and a laser heater 2. The outer surface of the heat-conducting cylinder 1 is the roller surface of the heating roller. During the heating operation, the material can be heated by heat transfer when passing through the outer surface of the heat-conducting cylinder 1. The specific structural form of the laser heater 2 can be referred to the prior art and will not be described in detail here.
[0051] As one application example, the laser heater 2 is arranged inside the heat-conducting cylinder 1, and the heating end of the laser heater 2 is arranged toward the inner wall surface of the heat-conducting cylinder 1, so that the preset heating area on the heat-conducting cylinder 1 can be directly heated by the laser heater 2.
[0052] In some embodiments, a heat-absorbing coating may be provided on the inner wall surface of the heat-conducting cylinder 1 , so as to better absorb the irradiation heat of the laser heater 2 and transfer the heat to the heat-conducting cylinder 1 .
[0053] In some embodiments, the laser heater 2 can be provided as one or more than one; for example, the plurality of laser heaters 2 are arranged around the axis of the heat-conducting cylinder 1 and are provided inside the heat-conducting cylinder 1. In this case, the laser heater 2 can perform heating operations on a plurality of preset heating areas.
[0054] In some embodiments, based on the staggered arrangement of the plurality of laser heaters 2 along the axial direction of the heat-conducting cylinder 1, the heating operation of the entire effective inner wall surface of the heat-conducting cylinder 1 can be realized. For example, the heat-conducting cylinder 1 and / or the laser heater 2 are arranged in a rotatable form, and a single laser heater 2 can form an annular heating area for the heat-conducting cylinder 1, and the plurality of formed annular heating areas are spliced along the axial direction of the heat-conducting cylinder 1, so that the heating operation of the entire effective inner wall surface of the heat-conducting cylinder 1 can be formed.
[0055] In some embodiments, the heat-conducting cylinder 1 can be made transparent; for example, it can be made of glass, transparent plastic, etc. By setting the heat-conducting cylinder 1 to be transparent, the control of the laser heater 2 can be more intuitive.
[0056] By setting the laser heater 2 and setting the laser heater 2 inside the heat-conducting cylinder 1 to form a form of directly heating the heat-conducting cylinder 1, the advantages of rapid and stable heating of the laser heater 2 can be better utilized to heat the heat-conducting cylinder 1. Compared with the traditional technology of heating by heat-conducting oil, the present embodiment can complete the heating within a few seconds, so that the heat-conducting cylinder 1 can have higher heating response efficiency and better temperature difference control accuracy. In some application examples, the temperature error can be ≤1°C; moreover, the temperature rise effect can be disconnected by cutting off the laser heater 2, and no additional cooling measures are required, which can reduce the complexity of the internal structure of the heating roller, reduce the application cost, and thus improve the use effect of the heating roller.
[0057] As one application example, the relative position of the laser heater 2 in the heat-conducting cylinder 1 is adjustable.
[0058] In some embodiments, the relative position described herein is adjustable, which may include adjusting the heating angle formed between the laser heater 2 and the heat-conducting cylinder 1 when the laser heater 2 and the heat-conducting cylinder 1 rotate relative to each other; or may include adjusting the relative position formed between the laser heater 2 and the heat-conducting cylinder 1 by moving the laser heater 2 along the axial direction of the heat-conducting cylinder 1.
[0059] By setting the relative position of the laser heater 2 in the heat-conducting cylinder 1 to be adjustable, the flexibility of the laser heater 2 in application can be improved, so that the heating operation under different process requirements can be better met.
[0060] As one application example, a first adjustment mechanism 3 is provided on the heating roller corresponding to the laser heater 2 , and the first adjustment mechanism 3 can be used to adjust a heating angle formed between the laser heater 2 and the heat-conducting cylinder 1 .
[0061] By setting the first adjustment mechanism 3, the heating angle between the laser heater 2 and the heat-conducting cylinder 1 can be adjusted as needed, so as to better meet the process requirements.
[0062] As one application example, the first adjustment mechanism 3 includes a first motor 31 , which is transmission-connected to the main shaft 11 of the heating roller. The laser heater 2 is arranged on the main shaft 11 and is located inside the heat-conducting cylinder 1 .
[0063] In some embodiments, the first motor 31 and the main shaft 11 may be connected by a pulley transmission connection, a sprocket transmission connection, or a gear meshing connection.
[0064] In some embodiments, Figure 1 As shown, the first motor 31 and the main shaft 11 can be set to a gear meshing connection transmission mode, in which case the control accuracy of the rotation of the main shaft 11 is better.
[0065] By setting up the first motor 31 and drivingly connecting the first motor 31 to the spindle 11, the rotational movement of the spindle 11 can be controlled by controlling the operation of the first motor 31, thereby adjusting the heating angle of the laser heater 2 set on the spindle 11.
[0066] In some embodiments, mounting seats 111 are respectively disposed at both ends of the main shaft 11 , and the main shaft 11 is rotatably disposed on the mounting seats 111 .
[0067] In some embodiments, a first bearing 112 is disposed between the main shaft 11 and the mounting seat 111 .
[0068] By setting the mounting seat 111, the installation of the main shaft 11 can be facilitated; and by setting the first bearing 112, the coordination of the main shaft 11 during rotation can be improved, and the first motor 31 can drive and control the rotation of the main shaft 11.
[0069] As one application example, a second adjustment mechanism 4 is further provided on the heating roller corresponding to the laser heater 2 , and the second adjustment mechanism 4 can be used to adjust the relative position of the laser heater 2 in the axial direction of the heat-conducting cylinder 1 .
[0070] By setting the second adjustment mechanism 4, the relative position of the laser heater 2 in the axial direction of the heat-conducting cylinder 1 can be adjusted, so that the application of the laser heater 2 can be more flexible and can meet more process requirements.
[0071] As one application example, the second adjustment mechanism 4 includes a sliding seat 41 and a second motor 42. The laser heater 2 is arranged on the sliding seat 41 and changes its position as the sliding seat 41 slides. The second motor 42 is transmission-connected to the sliding seat 41 to control the sliding of the sliding seat 41.
[0072] In some embodiments, a slide rail 113 extending along the axial direction of the heating roller is disposed on the main shaft 11 , and the sliding seat 41 can be relatively slidably sleeved on the slide rail 113 .
[0073] In some embodiments, the transmission connection between the second motor 42 and the sliding seat 41 can also adopt any one of the transmission modes of a belt wheel transmission connection, a sprocket transmission connection and a gear meshing connection.
[0074] In some embodiments, when a pulley drive or a sprocket drive is adopted, the second motor 42 is used to drive the belt or chain to move, and the sliding seat 41 is connected to the belt or chain, so that the position of the sliding seat 41 can be regulated by the operation of the second motor 42.
[0075] In some embodiments, Figure 1 , 2 As shown in FIG. 3 , when a gear meshing transmission method is adopted, a screw rod 411 can be set on the slide rail 113, and the sliding seat 41 is threadedly connected to the screw rod 411; the second motor 42 and the screw rod 411 are connected by gear meshing, so that the position of the sliding seat 41 can be regulated by the operation of the second motor 42, and the gear meshing and screw rod transmission method can have a higher regulation accuracy.
[0076] By setting the sliding seat 41, it is convenient to install the laser heater 2 and also to realize the sliding movement of the laser heater 2 along the axial direction of the main shaft 11; and by setting the second motor 42, the sliding movement of the sliding seat 41 can be controlled to realize the position adjustment of the laser heater 2.
[0077] As one application example, a lead hole 114 is provided on the main shaft 11 for the wire 5 to pass through; Figure 1 As shown, the first motor 31 can be disposed at one end of the main shaft 11 , and the lead hole 114 can be disposed at the other end of the main shaft 11 .
[0078] In some embodiments, the lead hole 114 is coaxially arranged with the main shaft 11 ; and one end of the lead hole 114 passes through the end of the main shaft 11 , and the other end of the lead hole 114 passes through the side of the main shaft 11 and is arranged in the heat conductive cylinder 1 .
[0079] The wire hole 114 can be easily inserted into the wire 5 to supply power to the laser heater 2 and the second motor 42. The introduction of the wire 5 can make fuller use of the spindle 11. The overall structure is simple and the design is ingenious.
[0080] As an example of one application, Figure 1As shown, a first end cover 12 and a second end cover 13 are respectively provided at both ends of the heat-conducting cylinder 1, and the first end cover 12 and the second end cover 13 are respectively sleeved on the main shaft 11 of the heating roller.
[0081] In some embodiments, a second bearing 14 is disposed between the first end cover 12 , the second end cover 13 and the main shaft 11 .
[0082] The first end cover 12 and the second end cover 13 can facilitate the installation of the heat-conducting cylinder 1 on the main shaft 11; and the second bearing 14 can facilitate the improvement of the coordination of the heat-conducting cylinder 1 during rotation.
[0083] In addition, this embodiment also provides a heating device, on which at least one heating roller as described above is arranged.
[0084] By applying the heating roller provided in this embodiment to the heating device, the heating device can have a higher heating response efficiency, which is convenient for improving operating efficiency; at the same time, it is also convenient to improve the applicability of the heating device and realize a regional heating scheme to meet the heating operations under more process requirements.
