Description

Technical Field

[0001] This utility model relates to the technical field of drying oven supporting equipment, specifically to a traction device. Background Technology

[0002] Drying ovens are commonly used equipment for drying profiles. They contain a drying space, which typically includes racks for supporting the profiles. To improve operational convenience, existing technologies often incorporate a track structure within this drying space, allowing the racks to move along the track. This enables the profiles to be moved into the drying space during loading and removed after drying.

[0003] However, the current process of moving the placement racks is highly dependent on manual operation. Especially after the profiles have finished drying, operators need to enter the high-temperature drying space to manually push out the placement racks. This operation is not only labor-intensive and inefficient, but also creates a harsh working environment due to the residual high temperature (often reaching tens to hundreds of degrees) in the drying space, posing a risk of burns to personnel.

[0004] Therefore, the existing technology still needs further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a traction device to solve the technical problem in the prior art that after the profile has been dried, the operator needs to enter the high-temperature drying space to manually push out the placement rack.

[0006] To achieve the above-mentioned technical objectives, according to one aspect of this utility model: a traction device is provided, comprising: a frame, a traction seat, and a locking rod. The frame is movably arranged along a preset trajectory; the traction seat is installed on the top of the frame and is located on the side of the frame closer to the drying oven; the traction seat has an insertion slot extending along the length direction of the frame; the insertion slot is for placing a traction fitting on the frame for insertion and engagement; the locking rod extends along the width direction of the frame and is movably inserted into the traction seat along the width direction of the frame; locking... The side wall of the insertion end of the rod is provided with a guide slope, and the locking rod has an initial state, a clearance state, and a locked state. When the traction seat is away from the placement frame, the insertion end of the locking rod is located in the insertion groove, and the locking rod is in the initial state. When the insertion part of the traction coupling abuts against the guide slope, the insertion end moves away from the insertion groove, and the locking rod is in the clearance state. When the insertion part of the traction coupling completes the insertion engagement with the insertion groove, the locking rod passes through the insertion part of the traction coupling and engages with the traction seat, and the locking rod is in the locked state.

[0007] Furthermore, the traction device also includes: a guide seat, which is installed on the top of the frame, and the guide seat and the traction seat are spaced apart along the width direction of the frame. The guide seat has a guide channel that extends along the moving direction of the locking rod, and at least a portion of the locking rod passes through the guide channel; and an elastic element, which is sleeved on the locking rod and located between the guide seat and the traction seat. The elastic element is connected to the guide seat and the locking rod respectively.

[0008] Furthermore, the traction device also includes: a first stop plate, which is sleeved on the locking rod, located between the elastic member and the traction seat, and is fixedly connected to the locking rod. The end of the elastic member near the traction seat abuts against the first stop plate.

[0009] Furthermore, the traction device also includes: a second stop plate, which is installed on the side of the guide seat near the traction seat, and the end of the elastic element away from the traction seat abuts against the second stop plate; the second stop plate is provided with a clearance hole for avoiding the locking rod, the clearance hole extends along the moving direction of the locking rod, and the clearance hole communicates with the guide channel.

[0010] Furthermore, the traction device also includes: a pair of traveling wheels, which are spaced apart on the frame along the width direction of the frame, and each traveling wheel is rotatably mounted relative to the frame; two traveling tracks, which are spaced apart on the installation reference along the width direction of the frame, and each traveling track extends along a preset trajectory; each traveling wheel is correspondingly mounted to the corresponding traveling track, and each traveling wheel rolls in cooperation with the corresponding traveling track to drive the frame to move along the extension direction of the traveling track.

[0011] Furthermore, the traveling wheel is a traveling gear, and the traveling track is a rack and pinion track, with the traveling gear meshing with the rack and pinion track.

[0012] Furthermore, the traction device also includes a drive assembly, which is driven to a pair of traveling wheels to drive each traveling wheel to rotate.

[0013] Furthermore, the frame has an operating space inside, and a pair of wheels are located within the operating space.

[0014] Furthermore, the traction device also includes an electrical control cabinet, which is mounted on the frame and is communicatively connected to the drive assembly to control the drive assembly to perform actions.

[0015] Furthermore, the traction device also includes: four load-bearing wheels, which are spaced apart along the edge of the frame, and each load-bearing wheel is rotatably mounted on the outer wall of the frame via a corresponding support frame.

[0016] Beneficial effects:

[0017] The present invention provides a traction device comprising a frame, a traction seat, and a locking rod. The frame is movably positioned along a preset trajectory, allowing it to approach or move away from the drying oven. The traction seat is mounted on the top of the frame, located on the side closest to the drying oven. An insertion slot is provided on the traction seat, extending along the length of the frame, to accommodate and engage the traction fitting on the placement frame. When the placement frame is connected to the traction device, its traction fitting is inserted into the insertion slot, achieving initial docking. The locking rod extends along the width of the frame and is movably inserted into the traction seat along the width of the frame. The locking rod locks the traction seat and the traction fitting on the placement frame, ensuring stability and reliability during traction. Furthermore, a guide slope is provided on the side wall of the insertion end of the locking rod, facing the traction fitting, to guide the traction fitting smoothly into the locking position during docking. The locking rod has three states: initial state, avoidance state, and locked state. Specifically:

[0018] When the traction seat is away from the placement frame, the insertion end of the locking rod is located in the insertion slot and is in an unloaded state; thus, the locking rod is in its initial state. When the frame moves towards the placement frame, the insertion part of the traction fitting contacts the guide slope and exerts a pressing force. The insertion end of the locking rod is subjected to external force and moves away from the insertion slot, thereby providing clearance space for the insertion of the traction fitting and facilitating its smooth entry into the insertion slot. At this time, the locking rod is in a clearance state. When the insertion part of the traction fitting is fully inserted into the insertion slot and completes docking with the traction seat, the locking rod resets and passes through the insertion part of the traction fitting to engage with the traction seat, realizing the locking connection between the traction seat and the traction fitting, ensuring stability during the traction process. At this time, the locking rod is in a locked state.

[0019] As can be seen, a fully functional and coordinated traction system is constructed through the ingenious cooperation between the frame, traction seat, and locking rod. The traction seat is installed on the top of the frame, located on the side closest to the drying oven. It has an insertion slot extending along the length of the frame, providing a precise insertion position for the traction fittings on the frame, thus ensuring good stability and directionality during the traction process. More importantly, the side wall of the insertion end of the locking rod is provided with a guide slope. During the insertion of the traction fitting into the insertion slot, this guide slope plays a good guiding role, allowing the locking rod to smoothly switch from the initial state to the avoidance state, effectively avoiding collisions or jamming between the locking rod and the traction fitting, and ensuring that the traction fitting can complete the insertion and engagement accurately and smoothly. Furthermore, the guide ramp design also possesses a mechanical conversion function: when the insertion part of the traction fitting contacts the guide ramp, the lateral force generated by the ramp pushes the locking rod to move, achieving automatic avoidance; after insertion, the locking rod automatically resets and passes through the insertion part of the traction fitting to form an insertion fit with the traction seat, thereby achieving a reliable locking connection between the traction seat and the traction fitting. This structural design not only achieves automatic docking between the traction device and the placement rack, but also completely eliminates the need for operators to manually hook the racks inside the high-temperature drying space, fundamentally eliminating the risk of burns and labor intensity caused by manual intervention, significantly improving operational safety and convenience. Simultaneously, the traction device has a simple overall structure and clear actions, facilitating linkage with the drying oven control system to achieve automated control of the placement rack entering and exiting the drying oven, further reducing reliance on manual operation and contributing to the development of intelligent and automated production lines. In summary, this traction device effectively addresses the technical problem in existing technologies where operators need to manually push out the placement racks inside the high-temperature drying space after the profiles have finished drying.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] Please see Figures 1 to 2 According to an embodiment of this utility model, a traction device is provided, including: a frame 1, a traction seat 2, and a locking rod 3. The frame 1 is movably arranged along a preset trajectory; the traction seat 2 is installed on the top of the frame 1, and the traction seat 2 is located on the side of the frame 1 closer to the drying oven. The traction seat 2 has an insertion slot 20, which extends along the length direction of the frame 1; the insertion slot 20 is used for inserting and engaging traction fittings on the frame; the locking rod 3 extends along the width direction of the frame 1, and the locking rod 3 is movably inserted into the traction seat 2 along the width direction of the frame 1; the insertion of the locking rod 3... The side wall of the end is provided with a guide slope 30, and the locking rod 3 has an initial state, a clearance state, and a locked state. When the traction seat 2 is away from the placement frame, the insertion end of the locking rod 3 is located in the insertion groove 20, and the locking rod 3 is in the initial state. When the insertion part of the traction coupling abuts against the guide slope 30, the insertion end moves away from the insertion groove 20, and the locking rod 3 is in the clearance state. When the insertion part of the traction coupling completes the insertion engagement with the insertion groove 20, the locking rod 3 passes through the insertion part of the traction coupling and engages with the traction seat 2, and the locking rod 3 is in the locked state.

[0027] As can be seen, the traction device provided by this utility model includes a frame 1, a traction seat 2, and a locking rod 3. The frame 1 is movably arranged along a preset trajectory, allowing it to move closer to or further away from the drying oven. The traction seat 2 is installed on the top of the frame 1, located on the side of the frame 1 closest to the drying oven. The traction seat 2 has an insertion slot 20 extending along the length of the frame 1, used to accommodate and engage the traction fitting on the placement frame. When the placement frame is connected to the traction device, its traction fitting is inserted into the insertion slot 20, achieving initial connection. The locking rod 3 extends along the width of the frame 1 and is movably inserted into the traction seat 2 along the width of the frame 1. The function of the locking rod 3 is to lock the traction seat 2 and the traction fitting on the placement frame, ensuring the stability and reliability of both during the traction process. Furthermore, the insertion end sidewall of the locking rod 3 is provided with a guide slope 30, which faces the traction mating component to guide the traction mating component smoothly into the locking position during the docking process. The locking rod 3 has three states: initial state, avoidance state, and locked state. Specifically:

[0028] When the traction seat 2 is away from the placement frame, the insertion end of the locking rod 3 is located in the insertion slot 20 and is in an unloaded state. Thus, the locking rod 3 is in its initial state at this time. When the frame 1 moves toward the placement frame, the insertion part of the traction fitting contacts the guide inclined surface 30 and exerts a pressing action. The insertion end of the locking rod 3 is subjected to external force and moves away from the insertion slot 20, thereby providing clearance space for the insertion of the traction fitting and facilitating its smooth entry into the insertion slot 20. At this time, the locking rod 3 is in a clearance state. When the insertion part of the traction fitting is fully inserted into the insertion slot 20 and completes docking with the traction seat 2, the locking rod 3 resets and passes through the insertion part of the traction fitting to engage with the traction seat 2, realizing the locking connection between the traction seat 2 and the traction fitting, ensuring stability during the traction process. At this time, the locking rod 3 is in a locked state.

[0029] As can be seen, a fully functional and coordinated traction system is constructed through the ingenious cooperation between the frame 1, the traction seat 2, and the locking rod 3. The traction seat 2 is installed on the top of the frame 1, located on the side closest to the drying oven. It has an insertion slot 20 extending along the length of the frame 1, providing a precise insertion position for the traction fittings on the frame, thus ensuring good stability and directionality during the traction process. More importantly, the side wall of the insertion end of the locking rod 3 is provided with a guide slope 30. During the insertion of the traction fitting into the insertion slot 20, the guide slope 30 plays a good guiding role, allowing the locking rod 3 to smoothly switch from the initial state to the avoidance state, effectively avoiding collisions or jamming between the locking rod 3 and the traction fitting, ensuring that the traction fitting can accurately and smoothly complete the insertion and engagement. Furthermore, the design of the guide ramp 30 also possesses a mechanical conversion function: when the insertion part of the traction fitting contacts the guide ramp 30, the lateral force generated by the force on the ramp pushes the locking rod 3 to move, achieving automatic avoidance; after insertion, the locking rod 3 can automatically reset and pass through the insertion part of the traction fitting to form an insertion fit with the traction seat 2, thereby achieving a reliable locking connection between the traction seat 2 and the traction fitting. The above structural design not only realizes the automatic docking between the traction device and the placement rack, but also completely avoids the need for operators to manually hook the racks inside the high-temperature drying space, fundamentally eliminating the risk of burns and labor intensity caused by manual intervention, and significantly improving operational safety and convenience. At the same time, the overall structure of the traction device is simple and the actions are clear, facilitating linkage with the drying oven control system to achieve automated control of the placement rack entering and exiting the drying oven, further reducing reliance on manual operation and helping to promote the development of the production line towards intelligence and automation. In summary, this traction device effectively solves the technical problem in the prior art where operators need to enter the high-temperature drying space to manually push out the placement rack after the profile has been dried.

[0030] Among them, the insertion slot 20 is an open slot.

[0031] Furthermore, the traction seat 2 is installed on the frame 1 by welding or by fasteners.

[0032] Furthermore, the traction seat 2 has a through hole that extends along the width of the frame 1 and communicates with the insertion slot. At least a portion of the locking rod 3 is movably inserted into the through hole.

[0033] Furthermore, the traction seat 2 includes a first support plate, a second support plate, and a third support plate connected in sequence. The first and third support plates are arranged opposite to each other, and the second support plate is located at the end of the first lower horizontal plate and the third support plate away from the placement frame. The first, second, and third support plates form an insertion slot 20, and through holes are provided on the first and third support plates. In the initial state and the avoidance state, at least a portion of the locking rod 3 passes through the through hole in the first support plate. When the locking rod 3 is in the locked state, the insertion end of the locking rod 3 passes through the insertion part of the traction fitting and is inserted into the through hole in the third support plate.

[0034] Furthermore, the insertion part of the traction fitting is provided with a through hole, which extends in the width direction of the frame 1. After the insertion part of the traction fitting is inserted into the insertion slot, the through hole is coaxially arranged with the through hole of the first support plate and the through hole of the third support plate.

[0035] Optionally, the cross-section of the locking lever 3 is circular.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, the traction device also includes: a guide seat 4 and an elastic element 5. The guide seat 4 is installed on the top of the frame 1. The guide seat 4 and the traction seat 2 are spaced apart along the width direction of the frame 1. The guide seat 4 is provided with a guide channel, which extends along the moving direction of the locking rod 3. At least a portion of the locking rod 3 passes through the guide channel. The elastic element 5 is sleeved on the locking rod 3 and is located between the guide seat 4 and the traction seat 2. The elastic element 5 is connected to the guide seat 4 and the locking rod 3 respectively.

[0037] With this structural design, the guide seat 4 has a guide channel through which at least a portion of the locking rod 3 passes. This makes the movement trajectory of the locking rod 3 more stable and precise when moving along the width direction of the frame 1, avoiding instability such as skewing or shaking during movement. This improves the accuracy and reliability of the engagement between the locking rod 3 and the traction seat 2 and traction coupling components, enhancing the stability and safety of the entire traction device. The elastic element 5 is sleeved on the locking rod 3 and located between the guide seat 4 and the traction seat 2, connecting to both. When the locking rod 3 is in an avoidance state under the push of the traction coupling component's insertion part, the elastic element 5 undergoes elastic deformation and stores elastic potential energy. Once the traction coupling component's insertion part completes its engagement with the insertion slot 20, the elastic element 5 releases the stored elastic potential energy, driving the locking rod 3 to automatically reset to the locked state. This achieves precise insertion and engagement between the locking rod 3 and the traction coupling component's insertion part, ensuring a secure locking connection between the traction seat 2 and the traction coupling component. This automatic reset function improves the operating efficiency and automation level of the traction device, reduces the need for manual intervention, and lowers the possibility of operational errors. Furthermore, during the process of the traction fitting insert abutting against the guide slope 30 and pushing the locking rod 3 to move, the elastic element 5 can play a buffering role, absorbing part of the impact force, reducing the impact load on the locking rod 3, traction seat 2 and related components, thereby extending the service life of each component of the traction device, reducing the risk of wear and damage to the components, and improving the durability and reliability of the traction device.

[0038] Furthermore, the guide channel 30 is coaxially arranged with the through hole.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the traction device also includes: a first stop plate 6, which is sleeved on the locking rod 3. The first stop plate 6 is located between the elastic member 5 and the traction seat 2. The first stop plate 6 is fixedly connected to the locking rod 3. The end of the elastic member 5 near the traction seat 2 abuts against the first stop plate 6.

[0040] With this structural arrangement, the first stop plate 6 abuts against the end of the elastic element 5 near the traction seat 2, providing a stable support point for the force transmission of the elastic element 5. This allows the elastic force of the elastic element 5 to be evenly transmitted to the locking rod 3 through the first stop plate 6 during the application and application of force, reducing deformation or stress concentration caused by uneven force on the elastic element 5 itself. Furthermore, since the first stop plate 6 is relatively fixedly connected to the locking rod 3 and located between the elastic element 5 and the traction seat 2, it can limit the skew or lateral movement of the elastic element 5 during the application of force. This limitation helps ensure that the compression or tension of the elastic element 5 is along its axial direction, thereby ensuring that its force direction is consistent with the applied force direction and avoiding uneven force due to lateral forces. In addition, the first stop plate 6 can effectively prevent the elastic element 5 from shifting axially on the locking rod 3. If the elastic element 5 shifts during the operation of the traction device, its force application point may change, thus affecting the balance of its force application and application. Through the limiting effect of the first stop plate 6, the elastic element 5 is always kept in its designed position, thereby ensuring the stability and consistency of the force receiving and applying process.

[0041] Preferably, the elastic element 3 is a spring.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the traction device also includes: a second stop plate 7, which is installed on the side of the guide seat 4 near the traction seat 2, and the end of the elastic member 5 away from the traction seat 2 abuts against the second stop plate 7; the second stop plate 7 is provided with a clearance hole for avoiding the locking rod 3, the clearance hole extends along the moving direction of the locking rod 3, and the clearance hole is connected to the guide channel.

[0043] With this structural arrangement, the second stop plate 7 is fixedly connected to the guide seat 4, and the end of the elastic element 5 away from the traction seat 2 abuts against the second stop plate 7, further restricting the axial displacement of the elastic element 5 when the locking rod 3 moves. This double-limiting design (the first stop plate 6 and the second stop plate 7 limit the movement at both ends) ensures that the elastic element 5 always remains in the correct position, avoiding uneven force or failure caused by the displacement of the elastic element 5. Due to the limiting and supporting role of the second stop plate 7, the elastic element 5 is more stable during force application and reset, reducing excessive deformation or fatigue damage to the elastic element 5. At the same time, guided by the clearance hole, the locking rod 3 can smoothly complete the clearance and locking actions, reducing friction and collision between the locking rod 3 and other components, thereby extending the service life of the locking rod 3 and the elastic element 5.

[0044] Specifically, such as Figure 1As shown, the traction device also includes: a pair of traveling wheels 8 and two traveling tracks 100. The pair of traveling wheels 8 are spaced apart on the frame 1 along the width direction of the frame 1, and each traveling wheel 8 is rotatably arranged relative to the frame 1. The two traveling tracks 100 are spaced apart on the installation reference along the width direction of the frame 1, and each traveling track 100 extends along a preset trajectory. Each traveling wheel 8 is arranged in a one-to-one correspondence with the traveling track 100, and each traveling wheel 8 rolls in cooperation with the corresponding traveling track 100 to drive the frame 1 to move along the extension direction of the traveling track 100.

[0045] With this structural arrangement, a pair of traveling wheels 8 are spaced apart along the width of the frame 1. This layout evenly distributes the weight of the frame 1 across the two traveling tracks 100. Compared to a single traveling wheel design, the dual-wheel design more effectively distributes the load, reducing the stress on each wheel and thus improving the overall load-bearing capacity of the traction device, enabling it to meet greater load demands. Furthermore, because the traveling wheels 8 and the traveling tracks 100 are in rolling contact, and the tracks 100 provide guidance, the traction device remains on the tracks during operation, effectively avoiding the risk of derailment. This is particularly important for traction devices operating in high-temperature, humid, or other harsh environments, ensuring their safe and reliable completion of traction tasks.

[0046] Furthermore, such as Figure 1 As shown, the traveling wheel 8 is a traveling gear, and the traveling track 100 is a rack and pinion track, with the traveling gear meshing with the rack and pinion track. This structural arrangement allows for precise power transmission to the frame 1, ensuring stable movement of the frame 1 along a preset trajectory. Furthermore, the meshing of the gear and rack effectively prevents the traveling wheel 8 from slipping on the traveling track 100, ensuring stable power transmission throughout the traction device's movement. Even under heavy loads or with slight dirt on the track surface, the frame 1 can still operate normally. Simultaneously, under heavy loads, the meshing of the traveling gear and rack and pinion track maintains stable power transmission and precise guidance, preventing instability or derailment due to excessive load, thus improving the reliability and safety of the traction device under heavy load conditions.

[0047] Specifically, the traction device also includes a drive assembly 9, which is drivenly connected to a pair of traveling wheels 8 to drive each traveling wheel 8 to rotate.

[0048] Furthermore, the drive assembly 9 is connected to the frame 1, and at least a portion of the drive assembly 9 is located above the frame 1.

[0049] Furthermore, the drive assembly 9 includes a drive motor and a reducer, the drive motor being connected to the reducer, and the reducer being driven by a pair of wheels 8.

[0050] Specifically, such as Figure 1 As shown, a movable space 10 is provided inside the frame 1, and a pair of traveling wheels 8 are located within the movable space 10. This structural arrangement, placing the traveling wheels 8 within the movable space 10 inside the frame 1 rather than exposing them to the outside, significantly reduces the overall footprint of the traction device. This compact design makes the traction device more suitable for use in space-constrained environments, such as narrow production lines or densely packed workshops. Furthermore, because the traveling wheels 8 are located inside the frame 1, the vibrations generated during their operation can be absorbed and isolated by the structural components of the frame 1, thereby reducing the impact on other components of the traction device. This results in smoother operation of the traction device and improves the overall operational quality.

[0051] Specifically, such as Figure 1 As shown, the traction device also includes an electrical control cabinet 11, which is mounted on the frame 1. The electrical control cabinet 11 is communicatively connected to the drive assembly 9, so as to control the drive assembly 9 to perform its actions. With this structural arrangement, by setting up the electrical control cabinet 11, the steering, speed and torque of the drive assembly 9 can be precisely controlled, thereby achieving precise adjustment of the moving direction and moving speed of the frame 1.

[0052] Specifically, such as Figure 1 As shown, the traction device also includes four load-bearing wheels 12, which are spaced apart along the edge of the frame 1, and each load-bearing wheel 12 is rotatably mounted on the outer wall of the frame 1 via a corresponding support frame 13. This structural arrangement, with the four load-bearing wheels spaced apart along the edge of the frame 1, allows the weight and load of the frame 1 to be evenly distributed across the four wheels. This even distribution reduces the force on each wheel, thereby improving the load-bearing capacity of the entire traction device.

[0053] Furthermore, the traction device also includes two guide rails 200, which are spaced apart along the width of the frame 1 and located on both sides of the frame 1, with the travel track located between the two guide rails 200. The two guide rails 200 extend along a preset trajectory to further guide and limit the movement path of the frame 1, ensuring its smooth operation in the set direction. Each guide rail 200 engages with two load-bearing wheels 12 located on the same side. That is, the frame 1 obtains stable guiding support during movement by having its load-bearing wheels 12 on both sides roll into contact with the corresponding guide rails 200, preventing deviation or swaying and improving the smoothness and guiding accuracy of the entire traction device.

[0054] Furthermore, the locking lever 3 includes a locking lever body and a handle, with the handle disposed on the end of the locking lever body away from the traction seat 2.

[0055] Optionally, the working process of the traction device is as follows:

[0056] Step 1, Frame positioning and preparation: The operator controls the drive component 9 to move through the electrical control cabinet 11, and then the drive component 9 controls the walking wheel 8 to move along the rack and pinion track, so that the traction device moves into the drying space of the drying oven; at this time, the locking rod 3 is in the initial state.

[0057] Step 2, placement frame docking trigger: As the traction device moves toward the position of the placement frame, the insertion part of the traction engagement component on the placement frame contacts the guide slope 30 of the locking rod 3. As the traction device 1 moves, the insertion part of the traction engagement component abuts against the guide slope 30 of the locking rod 3, thereby pushing the locking rod 3 to move away from the insertion slot 20 along the width direction of the frame 1, so as to avoid the insertion part of the traction engagement component. At this time, the elastic member 5 is in a compressed state.

[0058] Step 3, full insertion of the connector: As the traction device moves, the connector of the traction fitting slides into the insertion groove 20 until it reaches the bottom limit point of the groove. At this time, the through hole and the through hole of the connector of the traction fitting are coaxially arranged, and the connector of the traction fitting no longer applies pressure to the inclined surface.

[0059] Step 4, elastic reset and mechanical interlock: When the insertion part of the traction coupling no longer applies pressure to the inclined plane, the elastic element 5 releases its stored energy, pushing the locking rod 3 toward the insertion part of the traction coupling. Then, the insertion end of the locking rod 3 passes through the insertion part of the traction coupling and engages with the third support plate of the traction seat 3, thereby locking the rod 3 into the locked state.

[0060] Step 5, traction start and transfer: After docking is completed, the electrical control cabinet 11 controls the drive component 9 to change direction, and then the drive component 9 drives the walking wheel 8 to rotate in the opposite direction, thereby driving the frame 1 and the placement frame to move away from the drying oven along the preset trajectory.
