Description

Technical Field

[0001] The utility model belongs to the technical field of infrared coating curing equipment, in particular to an end lifting mechanism for infrared coating curing equipment catalyzed by a gas catalyst. Background Art

[0002] Infrared radiation heat can be directly transferred to the object being heated without the need for an intermediate medium, thus eliminating the heat loss caused by the intermediate medium. This makes it more energy-efficient than the convection heating method of traditional convection curing equipment. Furthermore, it is structurally simpler than convection curing equipment, making it easier to manufacture and install. Due to these characteristics, gas-fired catalytic infrared coating curing equipment is becoming increasingly widely used in industry.

[0003] However, for coating equipment that uses a power-up and free suspended conveyor line, infrared radiation panels can often only be fixedly arranged on the side of the workpiece. Fixed infrared radiation panels cannot be arranged at the front and rear ends of the workpiece along the forward direction of the conveyor line. For large workpieces, this will affect the overall curing effect of the workpiece, thereby affecting the quality of the product coating.

[0004] Therefore, the utility model proposes an end lifting mechanism for gas catalyst catalytic infrared coating curing equipment to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an end lifting mechanism for gas catalyst catalytic infrared coating curing equipment, which is suitable for coating various types of workpieces and can effectively improve the coating quality of the products.

[0008] External synchronous brackets are fixedly installed on both sides of the outside of the insulation furnace, and a synchronous sliding chain unit is arranged inside the external synchronous bracket. The bottom outer side of the external synchronous bracket is connected to the driving system, and a transmission rod is arranged on the inner side of the driving system. The other end of the transmission rod passes through the lifting sliding chain unit and the synchronous sliding chain unit to control the synchronous operation of the lifting sliding chain unit and the synchronous sliding chain unit, thereby driving the infrared radiation device to move up and down.

[0009] Moreover, the accumulation and release type suspension conveyor line includes a conveying frame, a load-bearing track, a hook, a workpiece and a control system. A load-bearing track is provided at the top of the conveying frame, and a number of hooks are fixed under the load-bearing track. Workpieces are hung on the hooks. The control system controls the start, stop, speed regulation, accumulation and release of the conveyor line to realize automatic control.

[0010] Moreover, the lifting bracket includes a first square tube, a second square tube, a slide rail and several connecting plates.

A lifting chain unit is provided in the first square tube, and the slide rails are fixed on the several connecting plates.

[0011] Moreover, a first limiting plate and a second limiting plate are provided between the first square tube and the second square tube. The first limiting plate is provided above the second limiting plate, and the first limiting plate and the second limiting plate are parallel to the plurality of connecting plates.

[0012] Moreover, the lifting chain unit includes a lifting chain and a lifting sprocket. The lifting sprocket is mounted on the transmission rod. The lifting chain passes through the first square tube and engages with the lifting sprocket. The other end of the lifting chain is connected to the infrared radiation device.

[0013] Moreover, the infrared radiation device includes an infrared radiation plate, a supporting crossbar and a lifting block. The lifting block is slidably connected to the slide rail, the supporting crossbar is fixed on the lifting block, and the infrared radiation plate is fixed on the supporting crossbar.

[0014] Moreover, the out-of-furnace synchronization bracket includes a control sensor and a synchronization sliding chain unit. The out-of-furnace synchronization bracket is composed of two square tubes, which are fixedly connected by several connecting plates. A synchronization sliding chain unit is arranged inside the square tube, and a control sensor is arranged on the top side of the square tube.

[0015] Moreover, the synchronous sliding chain unit includes a synchronous sliding chain, a synchronous sprocket and a synchronous sliding tube. The synchronous sprocket is mounted on the transmission rod. The synchronous sliding chain passes through the square tube and engages with the synchronous sprocket. A synchronous sliding tube is also mounted on the synchronous sliding chain. The synchronous sliding tube runs synchronously with the infrared radiation panel, and the operating position of the infrared radiation panel is determined according to the position of the synchronous sliding tube.

[0016] The advantages and positive effects of the utility model are:

[0017] 1. This utility model achieves precise vertical movement of the infrared radiation device through the coordination of the drive system, transmission rod, lifting and synchronizing sliding chain units.

[0019] 3. The lifting bracket of this utility model utilizes a combined structure of a first square tube, a second square tube, and several connecting plates, resulting in high strength and rigidity. Furthermore, the first and second limiting plates positioned between the first and second square tubes further enhance the stability of the lifting bracket, preventing shaking or deviation during lifting, thereby extending the service life of the equipment.

[0020] 4. The mid-infrared radiation device of this utility model maintains smooth movement during the lifting process through the sliding connection between the lifting block and the slide rail. At the same time, the end lifting mechanism can effectively avoid the position of the workpiece, and when the workpiece is not needed for irradiation, it descends to the bottom of the lifting bracket, further improving the versatility and applicability of the device.

[0021] 5. This utility model interlocks the infrared radiation device with the power-and-free overhead conveyor system to achieve infrared radiation heating of the front and rear ends of the workpiece along the conveyor line. This ensures the heat required for curing large workpieces at both ends, thereby ensuring the overall coating quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0030] An end lifting mechanism for gas-fired catalytic infrared coating curing equipment includes: a power-free hanging conveyor line, a heat-insulating furnace body 17, a drive system 20, a transmission rod 15, a synchronous bracket outside the furnace, an infrared radiation device, a slide rail, a lifting bracket, a lifting slide chain 13 unit, and a synchronous slide chain 14 unit. The heat-insulating furnace body 17 is provided at one end along the forward direction of the power-free hanging conveyor line. A plurality of lifting brackets are fixedly installed inside the heat-insulating furnace body 17. Each lifting bracket is provided with a lifting slide chain 13 unit. The lifting slide chain 13 unit is provided with a slide rail, and the infrared radiation device is slidably connected to the slide rail.

[0031] External synchronous brackets are fixedly installed on both sides of the outside of the insulation furnace, and a synchronous sliding chain 14 unit is arranged inside the external synchronous bracket. The bottom outer side of the external synchronous bracket is connected to the driving system 20, and a transmission rod 15 is arranged on the inner side of the driving system 20. The other end of the transmission rod 15 passes through the lifting sliding chain 13 unit and the synchronous sliding chain 14 unit to control the synchronous operation of the lifting sliding chain 13 unit and the synchronous sliding chain 14 unit, thereby driving the infrared radiation device to move up and down.

[0032] The accumulation and release type suspension conveyor line includes a conveying frame, a carrying rail 1, a hook 2, a workpiece 3 and a control system. The carrying rail 1 is provided at the top of the conveying frame, and a plurality of hooks 2 are fixedly installed under the carrying rail 1. The workpiece 3 is hung on the hook 2. The control system controls the start, stop, speed regulation, accumulation and release and other operations of the conveying line to realize automatic control.

[0033] The accumulation type hanging conveyor line is the main channel for the workpiece 3 to enter the coating and curing area. It extends along a specific direction and transports the workpiece 3 to be cured from one station to the location of the heat preservation furnace body 17.

[0034] The heat-insulating furnace body 17 can effectively maintain the internal high-temperature environment while reducing the impact of external temperature changes on the temperature inside the furnace, further improving the stability of the curing process.

[0035] The lifting bracket includes a first square tube 9, a second square tube 8, a slide rail and a plurality of connecting plates 11. The first square tube 9 is fixed to the second square tube 8 through the plurality of connecting plates 11. A lifting slide chain 13 unit is provided in the first square tube 9, and the slide rail is fixed on the plurality of connecting plates 11.

[0036] A first limiting plate 4 and a second limiting plate 16 are further disposed between the first square tube 9 and the second square tube 8. The first limiting plate 4 is disposed above the second limiting plate 16 and is parallel to the plurality of connecting plates 11. The provision of the first limiting plate 4 and the second limiting plate 16 further limits the position of the infrared radiation device so that it does not interfere with the movement of the workpieces 3 on the power-and-free suspension conveyor line.

[0037] The lifting chain 13 unit includes a lifting chain 13 and a lifting sprocket 18. The lifting sprocket 18 is mounted on the transmission rod 15. The lifting chain 13 passes through the first square tube 9 and engages with the lifting sprocket 18. The other end of the lifting chain 13 is connected to the infrared radiation device.

[0038] The infrared radiation device includes an infrared radiation panel 7, a support crossbar 6, and a lifting block 5. The lifting block 5 is slidably connected to a slide rail. The support crossbar 6 is fixedly mounted on the lifting block 5, and the infrared radiation panel 7 is fixedly mounted on the support crossbar 6. When the drive system 20 drives the transmission rod 15 to rotate, the transmission rod 15 drives the lifting sprocket 18 to rotate, which in turn drives the lifting chain 13 engaged with the lifting sprocket 18 to operate. At this time, the lifting chain 13 drives the support crossbar 6 connected to it to move, and in turn drives the infrared radiation panel 7 to move up and down.

[0039] The external synchronous support includes a control sensor 10 and a synchronous sliding chain 14. The support is composed of two square tubes, fixedly connected by a plurality of connecting plates 11. The synchronous sliding chain 14 is installed inside the square tubes, and the control sensor 10 is installed on one side of the top of the square tubes. The control sensor 10 can monitor the operating status of the power-and-free overhead conveyor in real time and provide accurate feedback to the control system for precise control of the power-and-free overhead conveyor. This allows the power-and-free overhead conveyor to work closely with the infrared radiation device, irradiating the workpiece 3 without hindering its operation.

[0040] The synchronous chain 14 unit includes a synchronous chain 14, a synchronous sprocket 19, and a synchronous slide tube 12. The synchronous sprocket 19 is mounted on the transmission rod 15. The synchronous chain 14 passes through a square tube and engages with the synchronous sprocket 19. The synchronous slide tube 12 is also mounted on the synchronous chain 14. The synchronous slide tube 12 operates synchronously with the infrared radiation panel 7, and the operating position of the infrared radiation panel 7 is determined by the position of the synchronous slide tube 12. Because the synchronous chain 14 and the lifting chain 13 are both connected to the transmission rod 15 through gear meshing, when the drive system 20 controls the rotation of the transmission rod 15, it can simultaneously drive the synchronous chain 14 and the lifting chain 13 units to operate. The operating status of the infrared radiation device can be determined by determining the position of the synchronous slide tube 12.

[0041] Working principle: During the operation of the power-and-free overhead conveyor line, the drive system controls the transmission rod to rotate, thereby driving the lifting and lowering slide chain unit and the synchronous slide chain unit to work synchronously. The infrared radiation plate connected to the lifting and lowering slide chain unit rises to a suitable position to irradiate the workpiece. After the irradiation is completed, the drive device controls the lifting and lowering slide chain unit to drive the infrared radiation plate to the bottom without hindering the workpiece from continuing to move forward. The operator can determine the position of the infrared radiation plate based on the position of the synchronous slide tube in the synchronous slide chain unit.

[0042] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
