Description

Technical Field

[0001] This utility model belongs to the technical field of automobile manufacturing industry, and more specifically, relates to a conveying device for automobile painting drying room. Background Technology

[0002] Automotive painting ovens are key equipment used in automobile manufacturing for drying and curing body paint. Their working principle is that during the production process, painted parts need to be placed in the oven for drying, and a stable temperature needs to be maintained inside the oven. The heat source is the high-temperature flue gas emitted after combustion in the oven's incinerator. After heat conversion of the high-temperature flue gas, the heat converted by the incinerator is carried into the oven by fresh air.

[0003] During the painting process, outside air enters the paint booth after undergoing multi-stage filtration and flows downwards at a certain speed, creating a clean painting environment. This process effectively prevents dust from affecting the paint surface.

[0004] Then the painting process begins: the damper is adjusted to the painting mode, and the hot air circulation quickly raises the indoor temperature to the set value (usually 55℃-60℃); fresh air is filtered and heated before being sent into the top air chamber, and then the heat energy is reused through internal circulation to maintain a constant temperature; when the preset time and temperature are reached, the system automatically stops operating.

The fixed frame 21 is horizontally arranged, and its length is greater than the length of the heating chamber 1. Both ends of the fixed frame 21 protrude from the heating chamber 1. The drive roller 22 and the driven roller 23 are rotatably connected to both ends of the fixed frame 21. The axial direction of the drive roller 22 is perpendicular to the length direction of the fixed frame 21, and the length direction of the driven roller 23 is perpendicular to the length direction of the fixed frame 21. The axial directions of the drive roller 22 and the driven roller 23 are parallel to each other and are on the same horizontal plane.

[0037] Please see Figure 1-6 As shown, the conveyor belt 24 is sleeved outside the drive roller 22 and the driven roller 23, and the inner surface of the conveyor belt 24 abuts against the outer surfaces of the drive roller 22 and the driven roller 23; the transmission belt moves periodically along the length direction of the fixed frame 21; the guide rail 25 is fixedly connected to the fixed frame 21, and the guide rail 25 is set on both sides of the conveyor belt 24.

[0038] In use, the workpiece is placed on the conveyor belt 24, and the conveyor belt 24 is driven by the rotation of the drive roller 22 to achieve the conveying operation. The guide rails 25 set on both sides of the conveyor belt 24 increase the stability of the conveyor belt 24 and reduce the probability of the conveyor belt 24 shifting left and right.

[0039] Please see Figure 1-6 As shown, the power unit 3 includes a drive gear 26 at one end of the drive roller 22. The drive gear 26 is coaxial with the drive roller 22 and is fixedly connected to the drive roller 22. The diameter of the drive gear 26 is larger than the diameter of the drive roller 22, and the outer surface of the drive gear 26 protrudes from the conveyor belt 24. The power unit 3 is located on the side of the drive gear 26 away from the heating chamber body 1.

[0040] Please see Figure 1-6 As shown, the power unit 3 includes a support frame 31, the length direction of which is perpendicular to the length direction of the fixed frame 21; a slide rail 32 is provided on the support frame 31, the length direction of which is the same as the length direction of the support frame 31; a motor frame 33 is slidably connected to the slide rail 32; a stepper motor 34 is fixedly connected to one end of the support frame 31 corresponding to the slide rail 32; a screw 35 is provided on the motor frame 33 corresponding to the position of the stepper motor 34, the axis of the screw 35 is the same as the length direction of the slide rail 32, one end of the screw 35 is fixedly connected to the output shaft of the stepper motor 34, and a threaded block 36 is fixedly connected to the lower part of the synchronously rotating motor frame 33 corresponding to the position of the screw 35, and the threaded block 36 is rotatably connected to the screw 35; a drive motor 37 is provided on the motor frame 33, and a drive gear 38 is fixedly connected to the output shaft of the drive motor 37, the drive gear 38 and the drive gear 26 can mesh with each other.

[0041] Please see Figure 1-6 As shown, a locking device 4 is provided on the support frame 31 corresponding to each drive gear 26; the locking device 4 includes a locking rod 41, which is vertically arranged, and a wedge block 42 is provided on the locking rod 41. The wedge block 42 can be inserted into the drive gear 26. A spring 43 is provided between the locking rod 41 and the support frame 31. The axis of the spring 43 is vertically arranged. One end of the spring 43 is fixedly connected to the locking rod 41, and the other end of the spring 43 is fixedly connected to the support frame 31. The spring 43 has the tendency to push the locking rod 41 to move closer to the drive gear 26. A limiting rod 44 is fixedly connected on the support frame 31 at the position corresponding to the locking rod 41. The limiting rod 44 is coaxial with the locking rod 41. A limiting groove 45 is opened on the locking rod 41 at the position corresponding to the limiting rod 44. The limiting rod 44 can be inserted into the limiting groove 45.

[0042] Please see Figure 1-6 As shown, two locking plates 46 are provided on the side of the locking rod 41 near the drive motor 37.

A pressure rod 47 is provided on the side of the drive motor 37 near the locking plate 46. The pressure rod 47 can abut against the upper surface of the locking plate 46. The pressure rod 47 is horizontally positioned.

[0043] The technical effects of this utility model are as follows: Improved conveying stability and accuracy: The guide rails 25 set on both sides of the conveyor belt 24 effectively constrain the lateral displacement of the conveyor belt 24, ensuring that the workpiece maintains a straight motion trajectory during transportation, reducing positioning errors caused by offset, and is suitable for high-precision processing or assembly scenarios.

[0044] Multi-station collaborative control is achieved: the power unit 3 adopts a movable drive motor 37 design, and the position of the motor frame 33 is adjusted by the stepper motor 34 driving the screw 35 mechanism, so that a single drive gear 38 can selectively mesh with multiple active gears 26; this design supports independent or synchronous control of multiple heating chambers 1, improves equipment flexibility, and adapts to different process requirements.

[0045] Quick locking and unlocking mechanism: The locking device 4 uses the pre-tightening force of the spring 43 to embed the wedge block 42 into the drive gear 26, realizing automatic locking in the non-working state and preventing the conveyor belt 24 from slipping unexpectedly; when driving, the pressure rod 47 triggers the locking plate 46, quickly releasing the locking rod 41, ensuring the immediacy and reliability of power transmission and shortening the equipment start-up and stop response time.

[0046] Enhanced equipment safety and energy efficiency: Locking device 4 physically blocks the transmission chain in non-drive state, avoiding energy consumption or safety hazards caused by misoperation; Modular power unit design reduces the number of redundant motors, and combined with the precise positioning function of stepper motor 34, reduces overall energy consumption.

[0047] Improved maintenance convenience and scalability: The separate design of the power unit 3 and the locking mechanism facilitates independent maintenance, and the standardized components of the guide rail 25 and the conveyor belt 24 support quick replacement; the length of the fixed frame 21 can be extended to adapt to heating chambers 1 of different sizes, reserving space for future production line upgrades.

[0048] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model.
