Description

Technical Field

[0001] This utility model relates to the field of paint oven conveyor belts, and in particular to a cleanable paint oven conveyor belt. Background Technology

[0002] A paint oven conveyor belt is a material conveying device specifically designed for through-type coating production lines. Essentially, it's a mesh conveyor belt composed of metal chains and support rods, primarily used to carry workpieces (such as furniture panels, metal shells, and automotive parts) continuously through a series of processes including the spray booth, leveling zone, and baking oven (paint oven), achieving automated production. In automated coating production lines for panel furniture and metal components, the conveyor belt must carry workpieces continuously through the spray booth and high-temperature baking oven. During this process, a large amount of overspray paint mist and dripping paint adheres to the surface of the conveyor belt. When these paint impurities enter the high-temperature baking oven with the workpieces, they undergo a thermosetting reaction, forming dense, firmly adhered hard paint sludge. This type of solidified paint sludge, especially the residue accumulated in the hinge gaps and inside the mesh, poses a significant challenge for cleaning operations.

[0003] In existing technologies, methods such as online high-pressure spray rinsing or offline ultrasonic cleaning are commonly used. However, high-pressure rinsing uses a large flow of high-pressure water to impact the chain mesh. Although it can remove some dirt, the violent impact can cause wastewater mixed with paint residue to splash everywhere. This not only contaminates the cleaned chain mesh section and surrounding equipment, but also makes the workshop floor slippery, posing a safety hazard. At the same time, the splashed impurities may also adversely affect the coating quality of subsequent workpieces. While ultrasonic cleaning after disassembling the chain mesh is thorough, it requires the production line to be shut down, which is cumbersome and time-consuming, seriously affecting production efficiency and continuous operation capability.

[0004] Therefore, a cleanable paint oven conveyor chain was designed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a cleanable paint oven conveyor chain, which solves the problem that existing methods of washing paint oven conveyor chains under high pressure can easily lead to wastewater splashing, causing secondary pollution and safety hazards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cleanable paint oven conveyor belt includes a mounting frame, a conveyor belt mounted on the mounting frame, a cleaning box located on top of the mounting frame, a painting area and a drying area, and spring roller shutters located on both sides of the opening of the cleaning box to prevent wastewater from splashing out.

[0007] Preferably, an installation box is fixedly installed at the top of the openings on both sides of the cleaning box, and a through groove is provided at the bottom of the installation box.

[0008] Preferably, the spring shutter is rolled up inside the mounting box, and its bottom end can extend downward and pass through the through slot.

[0009] Preferably, the curtain of the spring roller blind is made of fiberglass covered with PVC fabric, which makes it have a certain rigidity and can resist the impact of high-pressure water flow while still being easy to roll up; the spring roller blind can be lowered by manual pulling to close and isolate the openings on both sides of the cleaning box.

[0010] Preferably, a sealing strip is fixedly provided at the bottom end of the spring roller shutter, and when the spring roller shutter falls to the lowest position, the bottom end of the sealing strip is close to the surface of the conveyor chain mesh.

[0011] Preferably, a crossbar is hinged to the sealing strip via a damping hinge.

[0012] Preferably, the crossbar is T-shaped, and two fixed rods are fixedly installed on each of the symmetrical sides.

[0013] Preferably, the cleaning box has two sets of slots on both sides, and a sealing box is fixedly installed inside each slot. A fixing rod can be snapped into the slot. The cross-section of the slot and the sealing box are both teardrop-shaped, with a smaller top and a larger bottom, so that the fixing rod is not easy to slip upward after being snapped in.

[0014] Preferably, the cleaning box is equipped with multiple sets of high-pressure nozzles inside, and a water tank for supplying water to the high-pressure nozzles is fixedly installed on the top of the cleaning box.

[0015] Preferably, a collection box for collecting impurities is slidably provided at the opening of the mounting frame, and the painting area and drying area are used for painting and drying the workpiece, respectively.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a combination of spring roller blinds, sealing strips, and crossbars to form a sealed barrier. The spring roller blinds are made of specially formulated fiberglass-coated PVC fabric, which combines excellent rigidity, impact resistance, and flexibility. It effectively resists the impact of high-pressure water flow without tearing or deforming, effectively solving the problem of wastewater splashing caused by traditional open-type high-pressure washing. This reduces the probability of paint-containing wastewater contaminating the cleaned chain mesh, surrounding equipment, and workshop floor, lowering safety hazards and ensuring the coating quality of subsequent workpieces. The combination of teardrop-shaped slots and fixing rods improves the anti-fall-off effect. It ensures convenient connection while effectively solving the problem of accidental opening of the spring roller shutter due to water flow impact and vibration during high-pressure washing. The damping hinge makes the operation of the crossbar more stable and controllable, ensuring the stability of the spring roller shutter, effectively preventing sewage splashing, and improving cleaning effect and sealing.

[0024] Please see Figure 1-6 A cleanable paint oven conveyor belt includes a mounting frame 1, a conveyor belt 2 mounted on the mounting frame 1, a cleaning box 3 located on top of the mounting frame 1, a painting area 5 and a drying area 6, and spring roller shutters 4 mounted on both sides of the opening of the cleaning box 3 to prevent wastewater from splashing out. Mounting boxes 41 are fixedly installed at the top of the openings on both sides of the cleaning box 3. The bottom of the mounting box 41 is provided with a through groove 411. The spring roller blind 4 is rolled up inside the mounting box 41, and its bottom end can extend downward and pass through the through groove 411. The curtain of the spring roller blind 4 is made of fiberglass covered with PVC fabric, which makes it have a certain rigidity and can resist the impact of high pressure water flow while still being easy to roll up. The spring roller blind 4 can be lowered by manually pulling down to close and isolate the openings on both sides of the cleaning box 3. A sealing strip 42 is fixedly installed at the bottom of the spring roller blind 4. When the spring roller blind 4 falls to the lowest position, the bottom end of the sealing strip 42 is close to the surface of the conveyor chain mesh 2. The cleaning box 3 is equipped with multiple sets of high-pressure nozzles 31. A water tank 32 for supplying water to the high-pressure nozzles 31 is fixedly installed on the top of the cleaning box 3. A collection box 7 for collecting impurities is slidably installed at the opening of the mounting bracket 1. The painting area 5 and the drying area 6 are used for painting and drying the workpiece, respectively. When using this device, the conveyor chain 2 carries the workpiece through the painting area 5 for spraying, the drying area 6 for curing, and finally removes it. After the workpiece is removed, the paint-stained conveyor chain 2 eventually runs to the cleaning box 3 for online cleaning. When the conveyor chain 2 enters the cleaning box 3, the operator manually pulls down the spring roller shutters 4 on both sides to make the sealing strips 42 at the bottom of the conveyor chain 2 tightly abut against the surface of the conveyor chain 2, forming a closed space. Then the water tank 32 supplies water to multiple sets of high-pressure nozzles 31 to powerfully rinse the conveyor chain 2 and remove the cured paint residue. The wastewater and impurities after rinsing are collected by the collection box 7 below. After the treatment is completed, the roller shutter can automatically roll back and reset.

[0025] A horizontal bar 43 is hinged to the sealing strip 42 via a damping hinge 431. The horizontal bar 43 is T-shaped, and two fixed rods 432 are fixedly installed on both sides symmetrically. Two sets of slots 33 are opened on both sides of the cleaning box 3. A sealing box 34 is also fixedly installed inside each slot 33 of the cleaning box 3. The fixed rods 432 can be engaged inside the slots 33. The cross sections of the slots 33 and the sealing boxes 34 are teardrop-shaped, with the top being smaller and the bottom being larger. When the horizontal bar 43 is rotated to the vertical position, the fixed rods 432 are engaged inside the bottom end of the slots 33. The surface of the fixed rods 432 is covered with a rubber layer. After engagement, the spring roller shutter 4 will automatically roll up due to the spring effect, causing the bottom sealing strip 42 and the fixed rods 432 to move upward, so that the fixed rods 432 and the top area of ​​the slots 33 are interference-fitted, enhancing stability and making it difficult for the fixed rods 432 to slip upward after being engaged.

[0026] After manually pulling down the spring roller shutter 4 to its lowest position, the operator raises the crossbar 43 upwards, aligning the fixing rod 432 with and engaging it into the teardrop-shaped slot 33 on the side wall of the cleaning box 3. The resistance of the damping hinge 431 is used to position and initially stabilize the crossbar 43. After the fixing rod 432 is engaged, it forms a self-locking mechanism with the teardrop-shaped structure of the sealing box 34, which is smaller at the top and larger at the bottom. During this process, under the rebound force of the roller shutter, the fixing rod 432 tends to move upwards, thus forming an interference fit with the narrow part of the upper part of the slot 33, enhancing stability. At the same time, the angle of the crossbar 43 can be finely adjusted to make the sealing strip 42 better fit the surface of the conveyor chain mesh 2. Combined with the resistance of the damping hinge 431, the sealing effect is further improved.

[0027] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
