Description

Technical Field

[0001] This utility model relates to the field of paint booth technology, and in particular to a high-efficiency heating device for paint booths. Background Technology

[0002] A spray booth is an enclosed space specifically designed for painting operations. It is widely used in industries such as automobiles, furniture, and home appliances. It has a highly efficient ventilation system that can effectively remove harmful gases and dust generated during the spraying process, ensuring clean air. Existing spray booths have partition doors in the middle. When baking workpieces of different sizes, the partition doors are opened or closed, allowing small workpieces to be baked in a small space, which saves energy.

[0003] The existing spray painting booth partition doors are relatively simple and cannot be adjusted according to the size of the workpiece. In addition, the heating pipes are laid at the bottom. After the middle partition door is closed, only the heating pipes inside the partition door can be opened for heating and painting, which does not make full use of all the heating pipes and has low utilization efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the partition door of the existing spray painting booth is relatively simple and cannot be adjusted according to the size of the workpiece. Moreover, the heating pipe is laid at the bottom. After the middle partition door is closed, only the heating pipe inside the partition door can be opened for heating and baking, which does not make full use of all the heating pipes and has low utilization efficiency. Therefore, this utility model proposes a high-efficiency heating device for spray painting booths.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency heating device for a spray painting booth includes a shell and a load-bearing mesh, the load-bearing mesh being fixedly connected to the inner side wall of the shell; an adjustment mechanism is provided inside the shell, the adjustment mechanism including a sealing cavity, a rotating rod, a connecting block, and a heat insulation plate, the sealing cavity being fixedly connected to the side wall of the shell, the rotating rod being rotatably connected to the inner side wall of the sealing cavity, the outer surface of the rotating rod being textured, the connecting block being threadedly connected to the rotating rod, the heat insulation plate being fixedly connected to the upper end face of the connecting block, the heat insulation plate being slidably connected to the sealing cavity, and the heat insulation plate being slidably connected to the load-bearing mesh.

[0007] Preferably, a slider is fixedly connected to the upper end face of the insulation board, a groove is provided on the side wall of the load-bearing mesh, the slider is slidably connected in the groove, and a first partition is rotatably connected to the slider.

[0008] Preferably, the outer surface of the rotating rod is provided with reciprocating threads, and a pressing plate is threaded onto the rotating rod. An air bladder is fixedly connected between the pressing plate and the sealing cavity.

[0009] Preferably, an air outlet pipe is fixedly connected to the outer surface of the airbag, and an air inlet pipe is fixedly connected between the airbag and the shell. Both the air inlet pipe and the air outlet pipe are equipped with one-way valves.

[0010] Preferably, a second partition is rotatably connected to the housing, the second partition is slidably connected to the load-bearing mesh, a limit rod is fixedly connected to the inner wall of the sealed cavity, and the extrusion plate is slidably connected to the limit rod.

[0011] Preferably, a heating tube is fixedly connected to the bottom wall of the housing, and a turntable is fixedly connected to the end of the rotating rod away from the airbag, with a handle provided on the turntable.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the cooperation of structures such as insulation plate, slider, and first partition, the insulation plate and first partition can be moved by simply rotating the rotating rod. The size of the heating space can be adjusted at will according to the size of the workpiece, thereby minimizing the space to be heated. In conjunction with the insulation plate and the shell to form a partition, all heating tubes can be opened for heating, instead of only using the heating tubes in the partition, which greatly improves the heating speed and is very efficient.

[0014] 2. Through the cooperation of structures such as the extrusion plate, airbag, and limit rod, the gas inside the shell is continuously extracted when the first partition is adjusted, so that the air inside the shell is kept in a rarefied state, which prevents the heat insulation cotton from getting damp and failing, and also reduces the rate of heat dissipation, thereby allowing the temperature inside the partition to rise more quickly.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A high-efficiency heating device for a spray painting booth includes a shell 1 and a load-bearing net 2. (The shell 1 is equipped with a fan and other circulation equipment, which is existing technology and will not be described in detail again.) The shell 1 is made of hollow aluminum alloy or thin steel plate and is filled with heat insulation cotton inside. The internal gas is scarce. The heat insulation cotton serves both as heat insulation and support, preventing the shell 1 from deforming due to negative pressure. The load-bearing net 2 is fixedly connected to the inner wall of the shell 1. The workpiece and the absorbent blanket are placed on the load-bearing net 2. The load-bearing net 2 has multiple through holes to allow hot air to flow upward.

[0022] The housing 1 is equipped with an adjustment mechanism, which includes a sealing cavity 3, a rotating rod 4, a connecting block 5, and an insulation plate 6. The sealing cavity 3 is fixedly connected to the side wall of the housing 1, and the end of the sealing cavity 3 near the housing 1 also has good heat insulation effect to prevent heat loss. The sealing cavity 3 is the same length as the housing 1. The rotating rod 4 is rotatably connected to the inner side wall of the sealing cavity 3, and the outer surface of the rotating rod 4 is textured. The connecting block 5 is threadedly connected to the rotating rod 4, and the insulation plate 6 is fixedly connected to the upper end face of the connecting block 5. The insulation plate 6 is also... It is made of hollow thin steel plate or aluminum alloy, filled with thick heat insulation cotton, which has good heat insulation effect and the outer shell has a certain strength. The heat insulation board 6 is slidably connected to the sealing cavity 3 and the load-bearing net 2. The upper end face of the heat insulation board 6 is fixedly connected to the slider 7. The side wall of the load-bearing net 2 is provided with a sliding groove. The slider 7 is slidably connected in the sliding groove. The first partition 8 is rotatably connected to the slider 7. The slider 7, the sealing cavity 3 and the connecting block 5 provide limiting support for the heat insulation board 6 to prevent it from deforming.

[0023] The outer surface of the rotating rod 4 is provided with reciprocating threads. The threads on the rotating rod 4 are divided into two sections. A pressing plate 9 is threadedly connected to the rotating rod 4. The end of the rotating rod 4 connected to the pressing plate is shorter, and the end connected to the connecting block 5 is longer. An air bladder 10 is fixedly connected between the pressing plate 9 and the sealing cavity 3. An air outlet pipe 11 is fixedly connected to the outer surface of the air bladder 10. An air inlet pipe 12 is fixedly connected between the air bladder 10 and the shell 1. Both the air inlet pipe 12 and the air outlet pipe 11 are provided with one-way valves. The flow direction of the one-way valve in the inlet pipe 12 is from the housing 1 to the airbag 10, and the flow direction of the one-way valve in the outlet pipe 11 is from the airbag 10 to the outside. A second partition 13 is rotatably connected to the housing 1. The second partition 13 is slidably connected to the load-bearing net 2. A limit rod 14 is fixedly connected to the inner wall of the near-sealed cavity 3. The extrusion plate 9 is slidably connected to the limit rod 14. The limit rod 14 limits the extrusion plate 9 to prevent the extrusion plate 9 from rotating under the action of the rotating rod 4.

[0024] A heating tube 15 is fixedly connected to the bottom wall of the housing 1. A turntable 16 is fixedly connected to the end of the rotating rod 4 away from the airbag 10. A handle is provided on the turntable 16. The turntable 16 has a large diameter. Under the action of leverage, rotating the turntable 16 drives the rotating rod 4 to rotate without any effort.

[0025] When using this invention, if different workpieces need to be heated for painting, simply hold the worm gear and rotate the turntable 16 to drive the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the connecting block 5 to move. The connecting block 5 drives the insulation plate 6 and the slider 7 to move. The slider 7 drives the first partition 8 to move. The first partition 8 moves and forms a smaller compartment with the shell 1. The position of the first partition 8 can be changed according to the size of the workpiece, so that the baking can be carried out in the smallest space, which saves energy. It is very simple, quick and flexible to adjust.

[0026] After the first partition 8 creates a small compartment based on the size of the workpiece, all the heating tubes 15 can still be activated for heating. The insulation plate 6 blocks the hot airflow, so the gas heated by the heating tubes 15 can only flow out through the part not covered by the insulation plate 6. Therefore, no matter how small the space between the first partition 8 and the shell 1 is, all the heating tubes 15 can be opened for heating, instead of only opening the heating tubes 15 inside the partition. When heating small workpieces, all the heating tubes 15 heat the space inside the partition, which greatly improves the heating speed compared to a normal partition and is very efficient.

[0027] When the rotating turntable 16 and rotating rod 4 adjust the position of the first partition door 8 and the insulation plate 6, the reciprocating threads on the rotating rod 4, and the limiting action of the limiting rod 14, drive the extrusion plate 9 to reciprocate continuously. When the extrusion plate 9 moves away from the airbag 10 and stretches the airbag 10, the one-way valve in the air inlet pipe 12 opens and the one-way valve in the air outlet pipe 11 closes, and the gas in the shell 1 enters the airbag 10 through the air inlet pipe 12. When the extrusion plate 9 approaches the airbag 10, it squeezes the airbag 10, the one-way valve in the air inlet pipe 12 closes, and the one-way valve in the air outlet pipe 11 closes. When the one-way valve inside 11 opens, the gas inside the airbag 10 is discharged through the air outlet pipe 11. Each time the position of the first partition 8 is adjusted, the gas inside the shell 1 is extracted, keeping the air inside the shell 1 in a rarefied state. This prevents the internal insulation cotton from getting damp and losing its insulation effect. At the same time, the rarefied gas inside the shell 1 also reduces thermal conductivity, reduces energy loss, and accelerates the heating inside the shell 1. When the gas inside the shell 1 is rarefied, the airbag 10 will become deflated due to negative pressure, and will no longer extract gas when the extrusion plate 9 moves, until gas seeps into the shell 1 again.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
