Description

Technical Field

[0001] The utility model relates to the technical field related to the processing of hollow plates, in particular to a device for processing the frosted surface of hollow plates. Background Technique

[0002] Hollow plates are materials widely used in the fields of packaging, construction, advertising, agriculture, etc. When hollow plates are produced and processed, the materials and ingredients are first pretreated, and then an extruder is used to extrude the pretreated raw materials under high temperature and high pressure conditions to form a shape through a mold into the shape of a hollow plate. The hollow plate after extrusion molding needs to be quickly cooled by a cooling device, and generally, the air-cooling method is used for cooling.

[0003] When hollow plates are produced and processed, in order to better meet the market demand, sometimes when the hollow plates are exported by the extruder, their surfaces are processed into frosted surfaces, and then the air-cooling device will act cold air on the frosted surfaces of the hollow plates and cool them as a whole.

[0004] However, when the hollow plate with a frosted surface is just exported from the extruder, it is in a high-temperature state, and the overall shaping of its frosted surface is not stable, that is, it is extremely easy to deform when stressed. When the wind force of the air-cooling method acts on the frosted surface of the hollow plate, under the action of the blowing wind, the uneven patterns will receive a certain force, especially the top parts of the patterns are extremely easy to deform. Finally, the frosted surface of the hollow plate with deformed top parts will affect its overall beauty and practical effect.

[0005] Based on the above situation, it is necessary to design a device for processing the frosted surface of hollow plates to solve the above problems. Content of the Utility Model

[0006] The utility model provides a device for processing the frosted surface of hollow plates to solve the problem of cooling treatment of the frosted surface of hollow plates in the prior art.

[0007] The technical problems solved by the utility model are realized by adopting the following technical solutions:

[0008] A device for processing the frosted surface of hollow plates includes a roller conveyor. Above the roller conveyor, there is a pipeline connection mechanism with several output ends. The output ends of the pipeline connection mechanism are connected with water mist nozzles whose output ends face the roller conveyor. The input end of the pipeline connection mechanism is communicated with a telescopic pipe fitting, and one end of the telescopic pipe fitting far from the pipeline connection mechanism is connected with a water pump.

[0009] Preferably, it further includes a controller. A thermal imaging temperature sensor one for detecting the temperature of the hollow board is provided at the output end of the roller conveyor. The input end of the controller is connected to the output end of the thermal imaging temperature sensor one and is used to receive the temperature signal detected by the thermal imaging temperature sensor one. The output end of the controller is used to output a control signal, and the control signal is used to control the operation of the water pump.

[0010] Preferably, a thermal imaging temperature sensor two for detecting the temperature of the hollow board is provided at the input end of the roller conveyor. The input end of the controller is connected to the output end of the thermal imaging temperature sensor two. The input end of the controller receives the temperature detection signal of the hollow board by the thermal imaging temperature sensor two. The output end of the controller is used to output a control signal, and the control signal is used to control the operation of the water pump.

[0011] Preferably, the pipeline connection mechanism includes a plurality of pipeline connection sleeves and a connecting pipe for communicating the plurality of pipeline connection sleeves. The water mist nozzle is connected to the output end of the pipeline connection sleeve.

[0012] Preferably, the telescopic pipe fitting includes a fixed pipe and a movable pipe that is hermetically and slidably connected to the output end of the fixed pipe. The output end of the movable pipe is communicated with the input end of the pipeline connection mechanism, and the input end of the fixed pipe is connected to the output end of the water pump.

[0013] Preferably, a pipe cap for closing the connecting pipe is connected to one end of the pipeline connection mechanism away from the telescopic pipe fitting.

[0014] Preferably, a protective cover with an opening facing downwards is provided above the roller conveyor. The pipeline connection mechanism is connected inside the protective cover. A telescopic rod is connected to the roller conveyor, and the movable end of the telescopic rod is connected to the protective cover.

[0015] The beneficial effects of the present utility model are as follows: By providing a pipeline connection mechanism with a plurality of output ends above the roller conveyor, and the output end of the pipeline connection mechanism is connected to a water mist nozzle with an output end facing the roller conveyor. Under the action of the water pump, the water mist nozzle turns the cooling water into a mist and acts on the frosted surface of the passing hollow board. Under the action of the thermal imaging temperature sensor one and the thermal imaging temperature sensor two, the controller controls the operation of the water pump, and thus can adjust the cooling effect of the water mist nozzle on the hollow board. Compared with using air cooling, this cooling method is more effective in protecting the top of the frosted surface of the hollow board while cooling down. Description of the Drawings

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following further elaborates the present utility model in conjunction with specific illustrations.

[0024] Refer to Figures 1 - 5As shown in the figure, a hollow board matte surface treatment device includes a roller conveyor 1. The roller conveyor 1 is an existing technology device, and its main function is to convey the hollow board. After the hollow board is exported by an extruder (this structure is an existing technology device and is not shown in the figure), it is then imported by the roller conveyor. The hollow board is imported from the input end of the roller conveyor 1 and then exported from the output end of the roller conveyor 1. The exported hollow board will be sent to the next process. In order to cool the temperature of the hollow board, a pipe connection mechanism 2 with several output ends is provided above the roller conveyor 1. The output end of the pipe connection mechanism 2 is connected to a water mist nozzle 3 whose output end faces the roller conveyor 1. The input end of the pipe connection mechanism 2 is communicated with a telescopic pipe fitting 4. One end of the telescopic pipe fitting 4 away from the pipe connection mechanism 2 is connected to a water pump 5. The water pump 5 plays the role of strengthening the water pressure and introducing cooling water into the pipe connection mechanism 2. When the above structure is in use, the water pump 5 pressurizes and flows the water, and then introduces the water flow into the pipe connection mechanism 2 through the telescopic pipe fitting 4. Then, the cooling water will be sprayed out from the water mist nozzle 3. When the hollow board moves from its input end to the output end on the roller conveyor 1, it will pass under the water mist nozzle 3, and the water mist nozzle 3 turns the cooling water into a mist and acts on the matte surface of the hollow board. The misty cooling water will evaporate and absorb heat when it encounters high temperature, reducing the temperature of the hollow board and achieving the purpose of cooling the hollow board. Moreover, during the process, without the blowing force of wind cooling, no force is exerted on the top of the matte surface of the hollow board, greatly reducing the influence of the cooling mechanism on the top of the matte surface of the hollow board and ensuring the aesthetic degree of the matte surface of the hollow board.

[0025] A protective cover 10 with an opening downward is provided above the roller conveyor 1. The pipe connection mechanism is connected inside the protective cover 10 to ensure that the water mist nozzle 3 is more concentrated when atomizing the cooling water onto the hollow board, reducing the influence of the atomized water by the surrounding wind or environment. An expansion rod 11 is connected to the roller conveyor. The movable end of the expansion rod 11 is connected to the protective cover 10, and the expansion rod 11 can drive the protective cover 10 and the pipe connection mechanism 2 to move up and down, thereby adjusting the distance between the water mist nozzle 3 and the hollow board to adapt to hollow boards of different thicknesses and enhancing its practicability.

[0026] When the above structure is in use, according to the actual usage situation, water mist nozzles 3, pipe connection mechanisms 2, water pumps 5 and other structures can be provided both above and below the roller conveyor 1 to enhance the cooling effect on the hollow board.

[0027] Among them, the pipeline connection mechanism 2 includes a plurality of pipeline connection sleeves 201 and a connecting pipe 202 for connecting the plurality of pipeline connection sleeves 201. The water mist nozzle 3 is connected to the output end of the pipeline connection sleeve 201. The pipeline connection sleeve 201 ensures the stability of the water flow at the pipeline corner and the stability of the pipeline. The water mist nozzle 3 is threadedly connected to the output end of the pipeline connection sleeve 201. The pipeline connection sleeve 201 and the connecting pipe 202 are threadedly connected and can be replaced according to actual use requirements.

[0028] Furthermore, the telescopic pipe fitting 4 includes a fixed pipe 401 and a movable pipe 402 that is hermetically and slidably connected to the output end of the fixed pipe 401. The output end of the movable pipe 402 is connected to the input end of the pipeline connection mechanism 2. The input end of the fixed pipe 401 is connected to the output end of the water pump 5. When the telescopic rod 11 drives the protective cover 10 and the pipeline connection mechanism 2 to move up and down, the telescopic pipe fitting 4 ensures that the protective cover 10 and the pipeline connection mechanism 2 also receive the cooling water flow from the water pump 5 during movement.

[0029] Refer to Figure 4 As shown, furthermore, a pipe cap 9 for closing the connecting pipe 202 is connected to one end of the pipeline connection mechanism 2 away from the telescopic pipe fitting 4. The pipe cap 9 is threadedly connected to the connecting pipe 202 on the pipeline connection mechanism 2 away from the telescopic pipe fitting 4. The number of the connecting pipes 202 and the pipeline connection sleeves 201 on the pipeline connection mechanism 2 is increased or decreased according to the width of the hollow board. The installation and connection of the pipeline connection sleeves 201 are realized through the connection of the connecting pipes 202. The pipe cap 9 is threadedly connected to one end of the connecting pipe 202 where no pipeline connection sleeve 201 is installed, playing a role in blocking for use when adding pipeline connection sleeves 201 later. When adding pipeline connection sleeves 201, the pipe cap 9 is removed, and the connecting pipe 202 and the pipeline connection sleeve 201 can be connected.

[0030] Refer to Figure 1 As shown, the utility model further includes a controller 7. A thermal imaging temperature sensor 6 for detecting the temperature of the hollow board is provided at the output end of the roller conveyor 1. The thermal imaging temperature sensor 6 is a prior art structure and will not be described in detail here. When the hollow board passes by, the thermal imaging temperature sensor 6 will detect the temperature of the hollow board that has been atomized and cooled. The input end of the controller 7 is connected to the output end of the thermal imaging temperature sensor 6 for receiving the temperature signal detected by the thermal imaging temperature sensor 6. The output end of the controller 7 is used to output a control signal, and the control signal is used to control the operation of the water pump 5. If the hollow board fails to reach the preset cooling temperature after atomization cooling, at this time, under the adjustment of the controller 7, the water pump 5 changes its own power, which will in turn affect the atomization amount of the cooling water of the water mist nozzle 3, and timely make up for the problem of insufficient cooling of the hollow board.

[0031] Refer toFigure 1 As shown, further, a second thermal imaging temperature sensor 8 for detecting the temperature of the hollow board is provided at the input end of the roller conveyor 1. The second thermal imaging temperature sensor 8 is a structure of the prior art and will not be described in detail here. When the hollow board passes from the extruder to the roller conveyor 1, the second thermal imaging temperature sensor 8 will detect the temperature of the passing hollow board. The input end of the controller 7 is connected to the output end of the second thermal imaging temperature sensor 8. The input end of the controller 7 receives the temperature detection signal of the second thermal imaging temperature sensor 8 for the hollow board. The output end of the controller 7 is used to output a control signal, and the control signal is used to control the operation of the water pump 5, thereby changing the operating power of the water pump 5 and the atomization amount of the water mist nozzle 3. Different atomization amounts can be suitable for hollow boards at different temperatures, reducing waste of resources and avoiding the phenomenon of water droplets generated due to excessive water mist.
