[0049] Embodiment 1

[0050] Reference Figure 1 and Figure 2 On the one hand, the present application provides a long-distance oven, which includes a front-section leading mechanism 1, a rear-section leading mechanism 2, and a plurality of middle-section guiding mechanisms 3 arranged between the front-section leading mechanism 1 and the rear-section leading mechanism 2. The front-section leading mechanism 1 and the rear-section leading mechanism 2 are connected to traction with a steel belt 4, which is passed through the middle-section guiding mechanism 3. When the long-distance oven is in operation, the steel belt 4 is pulled by the front-section leading mechanism 1 and the rear-section leading mechanism 2, and the steel belt 4 directly or indirectly drives the coating material to move along a preset track through the middle-section guiding mechanism 3. It can be understood that the steel belt 4 is used to directly or indirectly drive the coating material to move, and the steel belt 4 can be a steel belt or a steel wire rope.

[0051] Specifically, the front-end belt-leading mechanism 1 and the rear-end belt-leading mechanism 2 are respectively located at the two ends and are symmetrically arranged, and the structures and working principles of the front-end belt-leading mechanism 1 and the rear-end belt-leading mechanism 2 are the same. Taking the front-end belt-leading mechanism 1 as an example, the front-end belt-leading mechanism 1 includes a front-end frame 11, a front-end traction assembly 12 arranged on the front-end frame 11, a front-end smoothing assembly 13 and a front-end driving assembly 14, and the front-end driving assembly 14 is used to synchronously drive the front-end traction assembly 12 and the front-end smoothing assembly 13.

[0052] Reference Figure 3 , Figure 4 and Figure 5 The front frame 11 is used to support and install various components. The front traction component 12 includes a traction roller 121 rotatably connected to the front frame 11 and a material tray 122 arranged on the traction roller 121. The traction roller 121 is arranged horizontally, and the material tray 122 is installed on the traction roller 121 and rotates with the rotation of the traction roller 121.

[0053] The front section leveling assembly 13 includes a reciprocating member 131 disposed above the material tray 122. In this embodiment, the reciprocating member 131 includes a screw rod 1311 rotatably connected to the front section frame 11 and a slider 1312 disposed on the screw rod 1311. The screw rod is located above the material tray 122 and is horizontally disposed. The screw rod 1311 is parallel to the traction roller 121. The slider 1312 is mounted on the screw rod. When the screw rod 1311 rotates, the slider 1312 can be driven to reciprocate along the length direction of the screw rod 1311. The slider 1312 is provided with a tensioning member 132. In this embodiment, the tensioning member 132 includes a mobile support frame 1321 mounted on the slider 1312 by a threaded connection. A uniform tensioning wheel group 1322 is mounted on the mobile support frame 1321. The steel belt 4 is sequentially passed through the uniform tensioning wheel group 1322 and then wound in the material tray 122. At the same time, in order to support and guide the movable support frame 1321, a horizontally arranged support rod is provided on the front frame 11, and the slider 1312 and the movable support frame 1321 are sleeved on the support rod and slidably connected to the support rod.

[0054] The front section drive assembly 14 includes a drive member 141 disposed on the front section frame 11, and the drive member 141 may be a motor, and the output shaft of the drive member 141 is coaxially connected with the traction roller 121. At the same time, a driving wheel 142 is disposed at one end of the traction roller 121, and a driven wheel 143 is disposed at the corresponding end of the screw rod 1311, and a synchronous belt 144 is disposed around the driving wheel 142 and the driven wheel 143.

[0055] During winding, the driving member 141 starts to drive the traction roller 121 to rotate, and the rotating traction roller 121 will synchronously drive the material tray 122 and the driven wheel 143 to rotate, and the rotating driven wheel 143 drives the screw rod 1311 to rotate, and the rotating screw rod 1311 drives the tensioning member 132 to move along the length of the screw rod 1311, so that the steel ribbon 4 is evenly wound from one end of the material tray 122 to the other end. During unwinding, the driving member 141 starts to drive the traction roller 121 to rotate in the opposite direction, and the steel ribbon 4 is evenly unwound from one end of the material tray 122 to the other end. Through such a setting, the error accumulation caused by the stacking and mutual entanglement of the steel ribbon 4 in the material tray 122 can be reduced.

[0056] In addition, the front frame 11 is also slidably connected to a driving tension wheel 145 for adjusting the tension of the synchronous belt 144. There are two driving tension wheels 145, which are located at one end of the front frame 11 and abut against both sides of the synchronous belt 144. The tension of the synchronous belt 144 can be adjusted by adjusting the degree of abutment of the driving tension wheel 145 against the synchronous belt 144. The structure and working principle of the rear lead mechanism 2 are the same as those of the front lead mechanism 1, and will not be described in detail.

[0057] Reference Figure 6 , Figure 7 and Figure 8 , a plurality of middle section guide mechanisms 3 are located between the front section guide mechanism 1 and the rear section guide mechanism 2, and the connection of the plurality of middle section guide mechanisms 3 is arranged in an arch shape to ensure tension. The middle section guide mechanism 3 includes a support block 31, a plurality of lower guide assemblies 32 arranged on the support block 31, and a plurality of upper guide assemblies 33. The support block 31 is used to support and install the lower guide assemblies 32 and the upper guide assemblies 33. It can be understood that the support block 31 can be a part of the oven, or a part independent of the oven.

[0058] The lower guide assembly 32 includes a lower guide wheel 321 rotatably connected to the support block 31 and lower guide protrusions 322 arranged on both sides of the lower guide wheel 321. There are two lower guide protrusions 322 and they are respectively arranged on both sides of the lower guide wheel 321. Under the encirclement and limitation of the two lower guide protrusions 322, the lower guide assembly 32 forms a lower guide groove adapted to the steel belt 4. When the steel belt 4 passes through, due to the limitation of the guide protrusions on both sides, the lower part of the steel belt 4 can only move along the length direction of the lower guide groove.

[0059] Similarly, the upper guide assembly 33 includes an upper support frame 331 slidably connected to the support block 31 and an upper guide wheel 332 rotatably connected to the upper support frame 331. Upper guide protrusions 333 are provided on both sides of the upper guide wheel 332. The upper guide protrusions 333 are formed with upper guide grooves adapted to the steel belt 4. More specifically, in order to install the upper support frame 331, the support block 31 is provided with a mounting column for matching the upper support frame 331. The mounting column is horizontally arranged and has a shoulder. The mounting column is provided with a guide column 3311 for matching the upper support frame 331. The guide column 3311 is vertically arranged. The upper support frame 331 is slidably connected to the guide column 3311, that is, the upper support frame 331 can rise or fall along the length direction of the guide column 3311. The guide column 3311 is sleeved with a compression spring 3312. The compression spring 3312 applies a force to the upper support frame 331 to continuously approach the lower guide assembly 32. That is, under the action of the compression spring 3312, the upper support frame 331 will tend to get closer to the lower guide assembly 32. At the same time, the upper support frame 331 is provided with a plurality of limit plates 3313 for limiting its own freedom. There are two limit plates 3313, one of which is in contact with the shoulder of the mounting column. Under the limitation of the two limit plates 3313, the upper support frame 331 cannot move except in the vertical direction.

[0060] Under the cooperation and limitation of the lower guide assembly 32 and the upper guide assembly 33, when the steel belt 4 enters the middle guide mechanism 3, the upper guide assembly 33 will be lifted up, and the upper guide assembly 33 will apply a downward pressure to the steel belt 4 to cooperate with the lower guide assembly 32 to limit the steel belt 4, so that the steel belt 4 is stably limited between the lower guide assembly 32 and the upper guide assembly 33, thereby achieving support for the steel belt 4 and avoiding errors caused by position offset of the steel belt 4 due to the long walking distance.

[0061] Replay Figure 6 In addition, the belt guide device also includes a front tensioning mechanism 6 and a rear tensioning mechanism 7 for maintaining the tension of the steel belt 4. The front tensioning mechanism 6 is arranged above the front belt guide mechanism 1, and is located between the front belt guide mechanism 1 and the middle guide mechanism 3. The front tensioning mechanism 6 includes a front fixed frame and a plurality of front tensioning wheel groups arranged on the front fixed frame; the rear tensioning mechanism 7 is arranged above the rear belt guide mechanism 2, and is located between the rear belt guide mechanism 2 and the middle guide mechanism 3. The structure of the rear tensioning mechanism 7 is the same as that of the front tensioning mechanism 6, and will not be repeated.

[0062] In order to improve the asynchronism phenomenon caused by the accumulation of errors during the use of the lead belt device, the steel belt 4 is provided with an identification member 41, and the long-distance oven is correspondingly provided with a detection mechanism 5 for detecting the position of the identification member 41. In this embodiment, the identification member 41 is a belt threading rod, and one steel belt 4 is threaded with two identification members 41, which are respectively threaded at both ends of the length direction of the steel belt 4, so as to be identified by the detection mechanism 5.

[0063] The detection mechanism 5 includes an origin detection component 51 for detecting the position of the identification component 41 and a distance detection component 52 for detecting the running distance of the steel belt 4. The origin detection component 51 and the distance detection component 52 face the steel belt 4. In this embodiment, the origin detection component 51 includes a front section origin detection component and a rear section origin detection component, and the front section origin detection component is arranged on the front section fixing frame. The front section origin detection component can be a proximity switch or an origin switch. Similarly, the rear section origin detection component is arranged on the rear section tensioning mechanism 7. The distance detection component 52 includes a front section distance detection component, and the front section distance detection component is arranged on the middle section guide mechanism 3 closest to the front section lead mechanism 1. The front section distance detection component can be an encoder. Similarly, the rear section distance detection component is arranged on the middle section guide mechanism 3 closest to the rear section lead mechanism 2.

[0064] By providing an identification piece 41 on the steel belt 4 and providing a detection component to detect the position of the identification piece 41 and the travel distance of the steel belt 4, it is only necessary to use the position of the identification piece 41 as the starting point to ensure that the starting point of each lead is the same; at the same time, the leading speeds of the front leading mechanism 1 and the rear leading mechanism 2 are adjusted according to the travel distance of the steel belt 4, so as to ensure the synchronous operation of the steel belt 4, thereby effectively avoiding skewing and jamming damage caused by error accumulation.

[0065] In addition, in the middle section guide mechanism 3, in order to adapt to the identification member 41, the lower guide protrusion 322 and the upper guide protrusion 333 are both gear-shaped, and the lower guide protrusion 322 and the upper guide protrusion 333 are set to be gear-shaped for adaptation. When the identification member 41 passes through the middle section guide mechanism 3, the identification member 41 will drive the gear-shaped protrusion to rotate, on the one hand, to avoid interference between the identification member 41 and the middle section guide mechanism 3, on the other hand, by observing the rotation state of the protrusion, the position of the identification member 41 can be known.

[0066] Embodiment 2

[0067] Reference Fig. 9 On the other hand, the present application provides a method for guiding a long-distance oven guiding device, comprising the following steps:

[0068] S1: Mark the same position of the steel belts on both sides of the oven, and evenly roll up the two ends of the steel belts at the two ends of the oven;

[0069] Specifically, the steel wires on both sides of the oven are marked. In this embodiment, there are two steel wires, and the same position at both ends of each steel wire in the length direction is marked by an identification piece. At the same time, the two ends of the steel wire are evenly rolled up on the front lead mechanism and the rear lead mechanism through the front leveling assembly and the rear leveling assembly, respectively.

[0070] S2: Forward leading is performed, the marks of the steel belts on both sides are detected at one end of the oven, and the marks are used as the starting points of leading, and the leading is performed from the marks;

[0071] Specifically, the front-end leading mechanism performs pre-unwinding, and the front-end leading mechanism operates to drive the steel wire to unwind, and the rear-end leading mechanism synchronously operates to rewind and provide tension. The front-end leading mechanism continues to drive the steel wire to unwind slowly until the origin detection component detects the identification piece. Then the front-end leading mechanism stops, and the position of the identification piece at the steel wire on both sides is the starting point, completing the zero point calibration. Finally, the front-end leading mechanism synchronously operates to drive the steel wire to unwind, and the rear-end leading mechanism synchronously operates to drive the steel wire to rewind, and performs forward leading.

[0072] S3: Detect and obtain the forward leading parameters in the forward leading process;

[0073] Specifically, S3 includes:

[0074] S3.1: Obtain the running distance of the steel wires on both sides during the guiding process;

[0075] Use the distance detection component to continuously detect the running distance of the steel belt with the identification part position as the starting point.

[0076] S3.2: Calculate and obtain the belt running speed of the steel belts on both sides according to the belt running distance obtained in S3.1;

[0077] The running distance and running time of the steel belt are obtained at preset time intervals, so as to calculate the running speed of the steel belts on both sides.

[0078] S3.3: Compare the speeds of the steel belts on both sides and calculate the speed difference between the steel belts on both sides.

[0079] The tape speed difference is calculated and obtained according to the tape speeds on both sides.

[0080] S4: adjusting the forward lead process in real time according to the forward lead parameters;

[0081] S4 specifically includes: taking one of the tape speeds as a reference, adjusting the other tape speed according to the tape speed difference, until the tape speed difference is adjusted to a preset range. In this embodiment, taking the smaller tape speed as a reference, adjusting the front lead mechanism and the rear lead mechanism on the side of the larger tape speed according to the tape speed difference, thereby adjusting the tape speed on this side, until the tape speed difference is adjusted to a preset range. This state is maintained until the forward lead ends.

[0082] S5: Recover the empty rods, detect the marks of the steel wire ropes on both sides at the other end of the oven, and use the marks as the starting point of the lead-in, and lead-in from the marks;

[0083] Similar to the forward guide, the rear guide mechanism performs pre-unwinding, and the operation of the rear guide mechanism drives the steel wire to unwind, while the front guide mechanism synchronously operates to rewind and provide tension. The rear guide mechanism continues to drive the steel wire to unwind slowly until the origin detection component detects the identification piece. The rear guide mechanism stops, and the position of the identification piece on both sides of the steel wire is the starting point, completing the zero point calibration. Finally, the rear guide mechanism synchronously operates to drive the steel wire to unwind, and the front guide mechanism synchronously operates to drive the steel wire to rewind, and the empty rod is recovered.

[0088] S6.2: Calculate and obtain the belt running speed of the steel belts on both sides according to the belt running distance obtained in S6.1;

[0089] The running distance and running time of the steel belt are obtained at preset time intervals, so as to calculate the running speed of the steel belts on both sides.

[0090] S6.3: Compare the speeds of the steel belts on both sides and calculate the difference in speed between the steel belts on both sides.

[0091] The tape speed difference is calculated and obtained according to the tape speeds on both sides.

[0092] S7: Real-time adjustment of the empty rod recovery process according to the empty rod recovery parameters.

[0093] S7 specifically includes: taking one of the tape speeds as a reference, adjusting the other tape speed according to the tape speed difference, until the tape speed difference is adjusted to a preset range. In this embodiment, taking the smaller tape speed as a reference, adjusting the front lead mechanism and the rear lead mechanism on the side of the larger tape speed according to the tape speed difference, thereby adjusting the tape speed on this side, until the tape speed difference is adjusted to a preset range. This state is maintained until the empty rod recovery is completed, and a complete lead process is completed.
