Description

Technical Field

[0001] The invention relates to the field of solar water tank foaming, and in particular to polyurethane foaming production line equipment for solar thermal insulation water tanks and a use method thereof. Background Art

[0002] Solar water heaters are already very mature and practical products, but in the entire production process of solar water heaters, there are major problems with the polyurethane foaming process of the insulated water tank. Since there are many vacuum pipe openings on the solar water tank, these holes must be blocked with foaming plugs during the polyurethane foaming process to prevent the polyurethane foam from flowing out of the pipe openings and to form a relatively smooth and beautiful surface at the pipe openings. Since polyurethane has a high degree of adhesion, before inserting the foaming plug into the water tank pipe opening, the surface of the foaming plug must be sprayed with a release agent to form a layer of release agent on the surface of the foaming plug, so that the solar water tank can be conveniently and easily pulled out after the foaming is completed. Since the foaming plug is sprayed with a release agent, it will not be stuck to the polyurethane, but the release agent is often sprayed directly in the atmospheric environment. The workshop for foaming the solar water tank needs to be closed and insulated, and the release agent is a chemical product with a strong irritating odor. Therefore, directly spraying the release agent in a closed atmospheric environment will not only pollute the environment, but also damage the health of the workers and deteriorate the production environment. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a solar thermal insulation water tank polyurethane foaming production line device and a use method thereof.

[0004] The present invention is achieved through the following technical scheme, providing a solar thermal insulation water tank polyurethane foaming production line equipment and a use method thereof, including a frame, a spray box, a sliding frame slidably connected to the frame, and a rotating frame rotatably connected to the sliding frame, the rotating frame is equipped with a foaming plug, the spray box is provided with an insertion hole adapted to the foaming plug, and also includes a rotary drive for driving the rotating frame to rotate and a sliding frame drive for driving the sliding frame to reciprocate between the spray box and the water tank.

[0005] In this scheme, the sliding frame is driven to reciprocate between the spray box and the water tank. Before the sliding frame moves to the spray box, the rotary drive drives the rotating frame to rotate, and the foaming plug is directed toward the spray box. Then, the sliding frame moves to insert the foaming plug from the insertion hole into the spray box, and the release agent is sprayed onto the foaming plug through the spray head inside the spray box. Then, the sliding frame moves to pull the foaming plug out of the spray box, and the rotating frame is driven to rotate by the rotary drive to direct the foaming plug toward the solar thermal insulation water tank, and the sliding frame moves to insert the foaming plug into the solar thermal insulation water tank, thereby blocking the pipe mouth with the foaming plug.

[0006] As an optimization, the sliding frame includes an upper sliding frame slidably connected to the upper end of the frame and a lower sliding frame slidably connected to the lower end of the frame, and the two ends of the rotating frame are respectively rotatably connected to the upper sliding frame and the lower sliding frame. In this solution, the two ends of the rotating frame are respectively rotatably connected to the upper sliding frame and the lower sliding frame, so that the rotating frame is driven to move horizontally by the horizontal movement of the upper sliding frame and the lower sliding frame, which is convenient for setting the rotating frame into a long strip shape and arranging multiple foaming plugs on the long strip rotating frame.

[0007] As an optimization, a synchronization mechanism is installed between the upper sliding frame and the lower sliding frame, and the synchronization mechanism includes a synchronization shaft, an upper synchronization gear fixed to the upper end of the synchronization shaft, and a lower synchronization gear fixed to the lower end of the synchronization shaft. The two ends of the synchronization shaft are rotatably connected to the upper sliding frame and the lower sliding frame respectively. The frame is fixed with an upper synchronization rack meshing with the upper synchronization gear and a lower synchronization rack meshing with the lower synchronization gear. In this solution, the upper synchronization gear meshes with the upper synchronization rack, and the lower synchronization gear meshes with the lower synchronization rack. Since the upper synchronization gear and the lower synchronization gear are fixed on the same synchronization shaft, the synchronization between the upper sliding frame and the lower sliding frame is achieved.

[0008] As an optimization, the slide frame drive includes two transverse cylinders fixed to the frame, and the two transverse cylinders drive the upper slide frame and the lower slide frame respectively. In this solution, the upper slide frame and the lower slide frame are driven to move by the two transverse cylinders, so that the upper slide frame and the lower slide frame can move synchronously and smoothly.

[0009] As an optimization, the rotary drive includes a rotary gear fixed to the rotary frame, a rotary rack slidably connected to the sliding frame, and a rotary cylinder driving the rotary rack to slide, and the rotary gear is meshed with the rotary rack. The rotary cylinder in this solution drives the rotary rack to slide, thereby driving the rotary gear to rotate through the rotary rack, thereby realizing the rotation of the rotary frame.

[0010] As an optimization, the spray box is connected to the frame by sliding horizontally, and at least two rows of insertion holes are opened on the spray box, and each row of insertion holes is arranged vertically. In this scheme, at least two rows of insertion holes are opened, so as to correspond to at least two types of solar thermal insulation water tanks with different hole spacings and hole numbers. By sliding the spray box horizontally and adjusting the distance and number of the foaming plugs on the rotating frame, it is suitable for different solar thermal insulation water tanks.

[0011] As an optimization, a spray box transverse movement cylinder for driving the spray box to slide transversely is fixedly connected to the frame. The spray box transverse movement cylinder in this solution drives the spray box to slide transversely, thereby realizing automatic switching.

[0012] As an optimization, the spray box is provided with a plurality of spray heads located on both sides of the insertion hole, and the spray heads are connected to the liquid inlet pipe. The liquid inlet pipe in this scheme provides a release agent to the spray head, and the release agent is sprayed onto the foaming plug in the spray box through the spray head.

[0013] As an optimization, the bottom of the spray box is connected with a collecting pipe. The collecting pipe in this solution discharges the release agent collected at the bottom of the spray box, so that the release agent can be recycled and reused.

[0014] A method for using a solar thermal insulation water tank polyurethane foaming production line device comprises the following steps:

[0015] a. The rotating frame is driven to rotate by a rotary drive, the foaming plug is directed toward the spray box, and the foaming plug is moved from the insertion hole of the spray box into the spray box by moving the sliding frame;

[0016] b. Spray the release agent onto the foam plug through the spray head inside the spray box;

[0017] c. The foaming plug is pulled out from the spray box by moving the sliding frame, and the rotating frame is rotated by the rotary drive to move the foaming plug toward the solar insulation water tank;

[0018] d. Insert the foam plug into the solar thermal insulation water tank by moving the sliding frame, so as to block the pipe opening by the foam plug.

[0019] The beneficial effects of the present invention are as follows: a solar thermal insulation water tank polyurethane foaming assembly line device and a method of using the same drive a sliding frame to reciprocate between a spray box and a water tank, and a rotating frame to rotate by a rotary drive, a foaming plug is inserted into the spray box from an insertion hole, a release agent is sprayed onto the foaming plug through a spray head inside the spray box, and then the foaming plug is inserted into the solar thermal insulation water tank, so that the pipe mouth is blocked by the foaming plug.

The entire process of spraying the release agent is carried out in a completely closed environment, the release agent will not diffuse into the air, and the excess release agent can be recycled and reused, which not only improves the environmental quality but also improves the work efficiency. At the same time, combined with other mechanical structures, the solar foaming process can also be automated. BRIEF DESCRIPTION OF THE DRAWINGS
