Description

Technical Field

[0001] The present invention relates to the field of solar water tank processing, in particular to the field of solar water tank foaming, and specifically refers to a solar water tank horizontal foaming device and a use method thereof. Background Art

[0002] During the entire solar water heater production process, 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 foam plugs during the polyurethane foaming process to prevent the polyurethane foam from flowing out of the pipe openings and at the same time form a smoother and more beautiful surface at the pipe openings. Since polyurethane has a high adhesiveness, before inserting the foam plug into the water tank pipe opening, the surface of the foam plug must be sprayed with a release agent to form a layer of release agent on the surface of the foam plug. In this way, the foam plug of the solar water tank can be conveniently and easily pulled out after foaming.

[0003] Invention patent CN202110400311.7 discloses a solar insulation water tank polyurethane foaming production line equipment and its use method. This invention patent can realize the spraying of release agent and vertical foaming of solar water tanks. However, when the solar water tank is vertically foamed, the positioning of the solar water tank is difficult, which is not conducive to the flow of the overall foaming production line. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a solar water tank horizontal foaming device and a method for using the same.

[0005] The present invention is achieved through the following technical solution, providing a horizontal foaming device for a solar water tank, comprising a frame, a rotating frame connected to the frame with a transverse axis, a spray box that moves along the radial direction of the rotating frame, and a lifting frame that rises and falls above the rotating frame. The water tank is placed on the lifting frame, and the rotating frame is equipped with a plurality of foaming plugs arranged along the length direction of the rotating axis. The spray box is provided with insertion holes adapted for the foaming plugs. The device also includes a rotary drive for driving the rotating frame to rotate, a spray box drive for driving the spray box to move radially, and a lifting drive for driving the lifting frame to rise and fall.

[0006] In this solution, the rotary drive drives the rotating frame to rotate, so that the foaming plug faces the insertion hole of the spray box or faces upward, the spray box drive drives the spray box to move along the radial direction of the rotating frame, so that the foaming plug is inserted into the spray box or pulled out from the spray box, and the spray head in the spray box sprays the release agent onto the foaming plug. The water tank is placed on the lifting frame, and the lifting drive drives the lifting frame to rise and fall, so that the foaming plug is inserted into the pipe opening of the water tank or pulled out from the pipe opening of the water tank.

[0007] As an optimization, a clamping device mounted on the frame includes clamping plates at both ends of the water tank and an electric push rod that drives the clamping plates to clamp the ends of the water tank. The electric push rod in this solution pushes the clamping plates to clamp the ends of the water tank, not only securing the water tank, but also preventing the ends of the water tank from falling out due to the squeezing force of the foaming process.

[0008] As an optimization, the two ends of the frame are equipped with sliding frames with adjustable distance, and the clamping plate and the electric push rod are both installed on the sliding frames. In this solution, the distance between the two sliding frames is adjustable to adapt to water tanks of different lengths and facilitate clamping of the clamping device.

[0009] As an optimization, the sliding frame is equipped with an auxiliary lifting device, comprising a bracket supported below the lifting frame and a bracket cylinder that drives the bracket up and down. The auxiliary lifting device in this solution uses the bracket cylinder to drive the bracket upward, thereby supporting the lifting frame below and assisting in its lifting. Because the auxiliary lifting device moves with the sliding frame, the lifting position can be adjusted according to the length of the water tank, reducing deformation of the lifting frame caused by the water tank's gravity.

[0010] As an optimization, the rotation drive includes a rack slidably connected to the frame and a rack cylinder driving the rack to move. One end of the rotating frame is fixedly connected to a rotating gear that meshes with the rack. In this solution, the rack cylinder drives the rack to move, thereby driving the rotating frame to rotate through the rotating gear.

[0011] As an optimization, the lifting drive includes a lifting cylinder installed at both ends of the frame, and the telescopic end of the lifting cylinder is connected to the end of the lifting frame. The lifting cylinder in this solution drives the end of the lifting frame to rise and fall, thereby realizing the lifting of the lifting frame.

[0012] As an optimization, the spray box is laterally slidably connected to the frame, and the spray box drive includes a transverse cylinder installed at both ends of the frame, and the telescopic end of the transverse cylinder is connected to the end of the spray box. In this solution, the spray box is laterally slidably connected to the frame, and the transverse cylinder drives the spray box to move laterally.

[0013] As an optimization, the lifting frame includes two side-by-side circular tubes, with the water tank nozzle located between the two tubes. In this solution, the lifting frame includes two side-by-side circular tubes, and the water tank is placed on the two circular tubes, so that the two circular tubes evenly support the water tank. The nozzle of the water tank is located between the two circular tubes, so that the foaming plug can be inserted into the nozzle from between the two circular tubes.

[0014] As an optimization, the frame includes several sealed tubes filled with high-pressure gas, and the frame is equipped with a battery. In this solution, the frame includes several sealed tubes. By filling the tubes with high-pressure gas, the gas source is provided to the cylinders in the foaming equipment, and the battery provides power. This allows the foaming equipment to circulate between the water tank placement station and the water tank removal station, realizing the automatic circulation of multiple foaming equipment.

[0015] A method for using a horizontal foaming device comprises the following steps:

[0016] a. The rotating frame is rotated by a rotary drive so that the foaming plug is directed toward the insertion hole of the spray box. The spray box is driven by the spray box to move toward the foaming plug so that the foaming plug is inserted into the spray box.

[0017] b. Spray the release agent onto the foam plug through the spray head in the spray box;

[0018] c. The spray box is driven to move in the reverse direction by the spray box drive, so that the foaming plug is pulled out of the spray box, and the rotary drive drives the rotating frame to rotate in the reverse direction so that the foaming plug faces upward;

[0019] d. The lifting drive drives the lifting frame down, places the water tank on the lifting frame, and inserts the foaming plug into the nozzle of the water tank;

[0020] e. Inflate the foaming plug to block the water tank opening, and then foam the water tank;

[0021] f. After the foaming is completed, the foaming plug is deflated, and the lifting frame and water tank are raised by the lifting drive, and then the water tank is removed to complete the foaming;

[0022] g. By moving the foaming equipment, multiple foaming equipment can be circulated between the water tank placement station and the water tank removal station, thereby realizing the automatic flow of multiple foaming equipment.

[0036] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0037] like Figures 1 to 10 As shown, a solar water tank horizontal foaming device of the present invention includes a frame 1, a rotating frame 4 connected to the frame 1 with a transverse axis, a spray box 6 moving along the radial direction of the rotating frame 4, and a lifting frame 3 rising and falling above the rotating frame 4.

[0038] The frame 1 is in the shape of a horizontal strip, and the rotating frame 4 is arranged horizontally, with both ends axially connected to the end portions of the frame 1 through circular shafts.

[0039] It also includes a rotary drive for driving the rotating frame 4 to rotate. The rotary drive includes a rack 11 slidingly connected to the frame 1 and a rack cylinder 12 driving the rack to move. The rack 11 is laterally slidably connected to one end of the frame 1. One end of the rotating frame 4 is fixed with a rotating gear 13 meshing with the rack 11. The rotating machine 4 is driven to rotate by the extension and retraction of the rack cylinder 12.

[0040] The rotating frame 4 is provided with a plurality of foaming plugs 5 arranged along the length direction of the rotating axis. The foaming plugs 5 are inflatable structures. When inflated, the outer diameter becomes larger, thereby blocking the pipe opening of the water tank. The spray box 6 is provided with an insertion hole adapted to the foaming plugs 5.

[0041] The spray box 6 is driven to move radially. The spray box 6 is located on one side of the rotating frame 4. The spray box 6 is laterally slidably connected to the frame 1. The spray box drive includes a transverse cylinder 15 installed at both ends of the frame 1. The telescopic end of the transverse cylinder 15 is connected to the end of the spray box 6. The two transverse cylinders 15 drive the two ends of the spray box 6 to move laterally respectively. When the foaming plug 5 on the rotating frame 4 rotates to the transverse position, the spray box 6 moves laterally toward the foaming plug 5, so that the foaming plug 5 is inserted into the spray box 6. The spray box 6 is equipped with a spray head, and the release agent is sprayed onto the foaming plug through the spray head.

[0042] The lifting frame 3 is located above the rotating frame 4, and the water tank is placed on the lifting frame 3. The lifting frame 3 includes two side-by-side circular tubes. The ends of the two circular tubes are connected as a whole through a connecting plate. The pipe mouth of the water tank is located between the two circular tubes. The circular tubes are parallel to the water tank. The water tank is placed on the two circular tubes, and the foaming plug 5 is inserted into the pipe mouth from between the two circular tubes.

[0043] It also includes a lifting drive for driving the lifting frame 3 to move up and down. The lifting drive includes lifting cylinders 14 installed at both ends of the frame 1. The lifting cylinders 14 are vertically fixed at the ends of the frame. The telescopic ends of the lifting cylinders 14 are connected to the ends of the lifting frame 3, so that the lifting frame 3 is driven to move up and down through the telescopic movement of the two lifting cylinders 14.

[0044] The two ends of the frame 1 are equipped with sliding frames 2 with adjustable distances. The two sliding frames are respectively connected to the frame 1 in a sliding manner along the length direction. The sliding frames 2 in this embodiment are connected to the frame 1 through sliders and slide rails. The sliding frames 2 are equipped with a vertically downward positioning cylinder 17, and the end of the positioning cylinder 17 is equipped with a positioning pin 18. The frame 1 is equipped with a plurality of positioning holes arranged along the length. The positioning pin 18 is driven by the positioning cylinder 17 to be inserted into the positioning hole to realize the positioning of the sliding frame 2 at different positions.

[0045] It also includes a clamping device installed on the frame 1, which includes a clamping plate 7 located at both ends of the water tank and an electric push rod 8 that drives the clamping plate to clamp toward the end of the water tank. The clamping plate 7 and the electric push rod 8 in this embodiment are both installed on the sliding frame 2. Two guide shafts are fixed to the rear end of the clamping plate 7. The sliding frame 2 is equipped with a guide sleeve, which moves in the guide sleeve through the guide shaft to guide the clamping plate 7. The electric push rod 8 is installed on the sliding frame 2 to drive the clamping plate 7 to move.

[0046] The sliding frame 2 is provided with baffles 16 on both sides of the splint 7. The function of the baffles 16 is to prevent the water tank from falling down by itself after the water tank has finished foaming and popped up upward, thereby stopping the water tank and ensuring that the water tank is not skewed.

[0047] The slide frame 2 is provided with an auxiliary lifting device, which includes a bracket 9 supported under the lifting frame 3 and a bracket cylinder 10 for driving the bracket 9 to move up and down. Figure 10 As shown, the lower end of the bracket 9 is provided with an arc surface corresponding to the circular tube of the lifting frame 3, and the arc surface is supported under the circular tube. When the sliding frame 2 moves, the bracket 9 moves along with it.

[0048] The foaming equipment can be moved, and can be moved by installing walking wheels, or can be guided by slide rails and sliders.

[0049] The frame 1 is equipped with a battery to supply power to the electrical components on the foaming device.

[0050] The frame 1 includes a plurality of sealed tubes filled with high-pressure gas. The frame 1 in this embodiment is formed by welding rectangular tubes, and the interior of the rectangular tubes is filled with high-pressure gas.

[0051] A method for using a horizontal foaming device comprises the following steps:

[0052] The rotating frame 4 is driven to rotate by the rotary drive, so that the foaming plug 5 faces the insertion hole of the spray box 6. The spray box drive drives the spray box 6 to move toward the foaming plug 5, so that the foaming plug 5 is inserted into the spray box 6.

[0053] The release agent is sprayed onto the foamed plug 5 through the spray head in the spray box 6 .

[0054] The spray box 6 is driven by the spray box to move in the reverse direction, so that the foaming plug 5 is pulled out of the spray box 6 , and the rotary drive drives the rotating frame 4 to rotate in the reverse direction, so that the foaming plug 5 faces upward.

[0055] The lifting drive drives the lifting frame 3 to descend, and the water tank is placed on the lifting frame 3, so that the foaming plug 5 is inserted into the pipe opening of the water tank.

[0056] Clamp both ends of the water tank with the clamping device.

[0057] The nozzle of the water tank is blocked by inflating the foaming plug 5, and then the water tank is foamed.

[0058] After the foaming is completed, the foaming plug 5 is deflated, and the lifting frame 3 and the water tank are driven to rise by the lifting drive, and then the water tank is removed to complete the foaming.

[0059] By moving the foaming equipment, multiple foaming equipment can be circulated between the water tank placement station and the water tank removal station, thereby realizing the automatic flow of multiple foaming equipment.
