Description

A polyurethane thermal insulation material spraying equipment Technical Field

[0001] The present invention relates to the technical field related to polyurethane injection molding, and in particular to polyurethane thermal insulation material spraying equipment. Background Art

[0002] Polyurethane foam is composed of Group A, which includes polyols, and Group B, which includes isocyanate flame retardants, catalysts, and blowing agents. Group A can be divided into polyols, among other additives. With the combined action of these additives, the high-molecular polymer is mixed using specialized equipment and foamed on-site via high-pressure spraying. After spraying and foaming, polyurethane foam exhibits excellent waterproofing, aging resistance, and thermal insulation properties. The thermal conductivity of the resulting polyurethane foam is approximately 0.025, which is superior to that of polystyrene boards, making it an excellent material for industrial insulation.

[0003] The gap inside the barrel of a solar water heater is usually filled with polyurethane material. The foamed polyurethane is sprayed into the annular space between the outer shell and the water tank. The foamed polyurethane fills the annular space after foaming and expansion. Currently, manual spraying is mostly done by manually holding a nozzle and spraying the foamed polyurethane into the annular space between the outer shell and the water tank. Because the common specifications of the barrel of a solar water heater are more than 1.5 meters in length, it needs to be sprayed multiple times. After the foaming of the sprayed foamed polyurethane is completed, the manual handheld nozzle is sprayed into the annular space again until the foamed polyurethane fills the annular space. However, manual spraying has the following disadvantages: manual spraying The nozzle cannot be kept in a vertical state, and the foamed polyurethane is easily sprayed onto the outer wall of the water tank or the inner wall of the shell. At this time, the foamed polyurethane cannot completely discharge the air at the bottom of the water heater barrel during the foaming and expansion process, which reduces the filling rate of the foamed polyurethane and affects the thermal insulation effect of the water heater barrel. Moreover, the different speeds of manual spraying around the water tank will make the foamed polyurethane spraying uneven, resulting in large differences in the foamed polyurethane filling volume of the annular space along its circumferential direction. During the foaming and expansion process after the next round of spraying, the air in the depression cannot be discharged in time and a closed space has been formed. Therefore, it is necessary to design a polyurethane insulation material spraying equipment.

[0035] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0036] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0037] As shown in Figures 1-11, a polyurethane thermal insulation material spraying device includes: a gantry 1, a horizontal limit rod 2 fixedly mounted on the gantry 1, and a plurality of spraying units spaced apart along the length of the limit rod 2 and mounted on the gantry 1;

[0038] The spraying unit includes a first slider 4 that can slide horizontally in a direction perpendicular to the length direction of the limit rod 2, a spraying mechanism fixedly mounted on the first slider 4, a mounting frame 5 fixedly mounted on the first slider 4 and located below the spraying mechanism, and a pair of bent clamping arms 7 arranged symmetrically with respect to the spraying mechanism along the length direction of the limit rod 2 and located above the limit rod 2 for clamping the water heater barrel 6. The inner sides of the pair of bent clamping arms 7 are arranged in a relative state and the ends near the first slider 4 can be detachably connected to the mounting frame 5. The bending part of the bent clamping arms 7 is mounted on the mounting frame 5 through a vertical rotating shaft 8. The end of the bent clamping arm 7 near the first slider 4 is provided with a first limit member 9 that can contact the limit rod 2. The spraying mechanism includes a horizontal mounting ring 10 fixedly mounted on the first slider 4 and a vertical spray head 11 that can slide on the mounting ring 10 along the circumferential direction of the mounting ring 10 and with the opening facing downward.

[0039] The water heater barrel 6 is divided into a cylindrical outer shell and a water tank installed inside the outer shell for holding water. The gap between the water tank and the outer cylinder forms an annular space. The open end of the water heater barrel 6 is placed on the ground with the first slider 4 moving close to the water heater barrel 6, driving the spray unit to move to the top of the water heater barrel 6. Because the nozzle 11 is in a vertical state, during the first round of spraying, the foamed polyurethane will be sprayed into the bottom of the water heater barrel 6. The nozzle 11 moves at a uniform speed along the circumferential direction of the mounting ring 10. The foamed polyurethane is sprayed into the bottom of the water heater barrel 6 during the foaming process. During the spraying process, the annular space of the water heater barrel 6 will be filled from bottom to top. After a certain period of time, the foamed polyurethane sprayed in the first round has completed the foaming process, and the spraying unit automatically performs the second round of spraying. The nozzle 11 moves at a uniform speed along the circumferential direction of the mounting ring 10 and sprays the foamed polyurethane into the annular space again. At this time, the foamed polyurethane will be sprayed on the polyurethane material that has been foamed in the previous round. The foamed polyurethane sprayed in the second round will foam and expand from bottom to top again. According to the above method, multiple rounds of spraying are carried out in sequence to fill the annular space.

[0040] The spraying unit can automatically spray foamed polyurethane, which not only improves work efficiency, but also the uniform movement of the nozzle 11 can spray the foamed polyurethane evenly and improve the spraying quality. Because the nozzle 11 is in a vertical state, each time the nozzle 11 foams polyurethane, it can spray to the bottom of the water heater barrel 6 or the top of the foamed polyurethane that has been foamed in the previous round. The foaming process of each round of foamed polyurethane is carried out from bottom to top, and the foamed polyurethane is evenly accumulated layer by layer, which avoids the unfilled space in the water heater barrel 6, improves the filling rate of the foamed polyurethane, and improves the filling quality.

[0041] The bent clamp arm 7 includes a first clamp arm arranged close to the first slider 4 and a second clamp arm fixedly connected to the first clamp arm and arranged away from the first slider 4. The first limiting member 9 is installed at the end of the first clamp arm away from the second clamp arm. When the first limiting member 9 contacts the limiting rod 2, as shown in Figures 4 and 7, the ends of the pair of first clamp arms are close to each other, and the ends of the pair of second clamp arms are away from each other. At this time, the water heater barrel 6 can be placed between the pair of second clamp arms. When the first slider 4 moves close to the water heater barrel 6, the mounting bracket 5 will also move close to the water heater barrel 6, and the first clamp arm will Obstructed by the water heater barrel 6, the bent clamp arm 7 rotates around the rotating shaft 8. At this time, the ends of the pair of first clamp arms move away from each other, and the ends of the pair of second clamp arms approach each other. When the mounting ring 10 moves to the top of the water heater barrel 6, the pair of first clamp arms and the pair of second clamp arms are in contact with the water heater barrel 6, and the pair of bent clamp arms 7 clamp the column water heater barrel 6. At this time, the end of the bent clamp arm 7 close to the first slider 4 is connected to the mounting frame 5, and the pair of bent clamp arms 7 will fixedly clamp the water heater barrel 6 to prevent it from tilting during the spraying process, thereby improving operational safety.

[0042] After the first stop member 9 contacts the limit rod 2, the limiting effect of the limit rod 2 will also push the bent clamp arm 7 to rotate. When the distance between the ends of the pair of second clamp arms is equal to the outer diameter of the water heater barrel 6, the water heater barrel 6 can no longer hinder the second clamp arm, and the first slider 4 continues to move. The limiting effect of the limit rod 2 will continue to push the bent clamp arm 7 to rotate, so that the distance between the ends of the pair of second clamp arms is greater than the outer diameter of the water heater barrel 6, so that the filled water heater barrel 6 can be taken away, and the next unfilled water heater barrel 6 can be directly placed between the pair of second clamp arms.

[0043] Several groups of spraying units can perform spraying work at the same time. After the corresponding water heater barrel 6 is placed and the corresponding spraying unit is started, the operator can replace the water heater barrel 6 that has been filled under other spraying units, thereby improving work efficiency.

[0044] A pair of second position-limiting members 12 symmetrically distributed with respect to the spraying mechanism are fixedly mounted on the mounting frame 5 , and the pair of second position-limiting members 12 are respectively located on the inner sides of the corresponding bent clamp arms 7 .

[0045] The function of the second limit member 12 is to limit the rotation range of the bent clamp arm 7. When the first limit member 9 contacts the limit rod 2, the side wall of the first clamp arm close to the second clamp arm will contact the second limit member 12, which will limit the bent clamp arm 7 from continuing to rotate. This is to prevent the bent clamp arm 7 from being touched and rotating during the process of replacing the water heater barrel 6, and in the process of the first slider 4 moving away from the water heater barrel 6, it can also prevent the bent clamp arm 7 from continuing to rotate due to inertia.

[0046] Pulleys 13 are mounted on both ends of the bent clamp arm 7 , with their axes in a vertical state and capable of contacting the outer wall of the water heater barrel 6 .

[0047] The pulley 13 can reduce the sliding friction between the bent clamp arm 7 and the water heater barrel 6, thereby preventing the bent clamp arm 7 from scratching the outer wall of the water heater barrel 6.

[0048] A positioning block 14 mounted on the ground is provided below each group of the spraying units. An arc-shaped positioning groove matching the water heater barrel 6 is formed on the positioning block 14 .

[0049] The positioning block 14 enables the operator to quickly position the water heater barrel 6, thereby improving work efficiency. By placing the lower part of the water heater barrel 6 into the arc-shaped positioning groove, the first slider 4 can move with the mounting ring 10 to the top of the water heater barrel 6.

[0050] The spraying mechanism also includes a mounting plate 15 coaxially arranged with the mounting ring 10 and located on the inner side of the mounting ring 10, a first annular slide 16 coaxially fixedly mounted on the mounting ring 10, a second annular slide 17 coaxially fixedly mounted on the mounting plate 15, a second slider 18 slidably connected to the first annular slide 16 and the second annular slide 17, an annular rack 19 coaxially fixedly mounted on the mounting plate 15, a motor 20 fixedly mounted on the second slider 18 and a gear 21 coaxially fixedly mounted on the output shaft of the motor 20 and meshing with the annular rack 19, the spray head 11 is assembled on the second slider 18, and the mounting plate 15 is fixedly connected to the mounting ring 10 via a connecting piece 32.

[0051] The motor 20 starts to drive the gear 21 to rotate, and the gear 21 will revolve and rotate around the annular rack 19 at a uniform speed, thereby driving the second slider 18 to slide on the first annular slide 16 and the second annular slide 17, and driving the spray head 11 to slide along the circumference of the mounting ring 10 to spray foamed polyurethane.

[0052] A mounting plate 22 fixedly mounted on the first annular slide 16 and connected to the second annular slide 17 is mounted on the mounting plate 22. A pair of metal sensors 23 arranged in a back-to-back state are mounted on the second slider 18. A pair of metal blocks 24 arranged in a back-to-back state and respectively matched with the corresponding metal sensors 23 are mounted on the second slider 18.

[0053] Because the mounting plate 22 is provided, the maximum sliding angle of the second slider 18 is 350 degrees, which will not affect the spraying effect of the foamed polyurethane. When the second slider 18 slides clockwise, when the corresponding metal block 24 approaches the corresponding metal sensor 23, the corresponding metal sensor 23 is triggered, and the motor 20 drives the gear 21 to rotate in the opposite direction, thereby driving the second slider 18 to slide counterclockwise until the corresponding metal block 24 approaches the corresponding metal sensor 23. After the corresponding metal sensor 23 is triggered, the second slider 18 will slide in the opposite direction again, so the second slider 18 slides back and forth on the first annular slide 16 and the second annular slide 17.

[0054] The connecting piece 32 is in a cylindrical shape and is sleeved outside the second annular slide 17 and the first annular slide 16 . The nozzle 11 is connected to a spiral hose 25 , and the end of the spiral hose 25 away from the nozzle 11 passes through the connecting piece 32 .

[0055] Because the second slider 18 slides back and forth on the first annular slide 16 and the second annular slide 17 , the nozzle 11 can be connected to the foaming polyurethane feeding device through the spiral hose 25 , and the cylindrical connecting piece 32 can also play a dust-proof role.

[0056] The positioning block 14 is provided with straps 26 on both sides of the arc-shaped positioning groove. The ends of the pair of straps 26 away from the positioning block 14 are detachably connected by movable buckles 27 .

[0057] The lower end of the water heater barrel 6 can be fixed in the arc-shaped positioning groove by means of the binding strap 26 and the movable buckle 27 .

[0058] The spraying unit also includes several horizontal guide rods 28 whose length directions are perpendicular to the length of the limit rod 2 and are all installed on the gantry 1, and a cylinder 29 parallel to the guide rods 28, which is fixedly installed on the top of the gantry 1 through a mounting seat and whose piston rod is fixedly connected to the first slider 4. The first slider 4 is slidably sleeved on several guide rods 28.

[0059] When the piston rod of the cylinder 29 moves close to the water heater barrel 6, it pushes the first slider 4 to slide close to the water heater barrel 6 on several guide rods 28; when the piston rod of the cylinder 29 moves away from the water heater barrel 6, it pulls the first slider 4 to move away from the water heater barrel 6 on several guide rods 28.

[0060] A metal plate 30 is fixedly mounted on the outer wall of the end portion of the bending clamp arm 7 close to the first slider 4 , and an electromagnet 31 matching the metal plate 30 is fixedly mounted on the mounting frame 5 .

[0061] The electromagnet 31 is a device that generates electromagnetic energy when powered. A conductive winding matching its power is wound around the outside of the iron core. This coil with current flowing through it has magnetism like a magnet. Such an electromagnet 31 is magnetic when powered, and the magnetism disappears when the power is turned off.

[0062] When a pair of bent clamp arms 7 are clamped on the water heater barrel 6, the electromagnet 31 is energized to tightly adsorb the metal plate 30, thereby fixing the bent clamp arms 7 on the mounting frame 5; when the water heater barrel 6 is filled, the electromagnet 31 is de-energized, and the bent clamp arms 7 can rotate around the rotating shaft 8.

[0063] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0064] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

The method for negotiating a scheduled wake-up period according to claim 5, wherein: The first access point sets a scheduled wake-up period according to a scheduled wake-up period of a neighboring access point so that the scheduled wake-up period of the first access point does not overlap with the scheduled wake-up period of the neighboring access point, including any one of the following: The first access point reads a broadcast message from a neighboring access point or receives an access point cooperation notification message sent by the neighboring access point to obtain a scheduled wake-up period during which the neighboring access point is in an activated state; the first access point sets a scheduled wake-up period based on the scheduled wake-up period during which the neighboring access point is in an activated state, so that the scheduled wake-up period of the first access point does not overlap with the scheduled wake-up period during which the neighboring access point is in an activated state; The first access point sends a second request message to the neighboring access point, where the second request message is used to request timed wake-up period information; The first access point receives a second response message sent by the neighboring access point, where the second response message indicates a scheduled wake-up period in an activated state; The first access point sets a scheduled wake-up period according to a scheduled wake-up period of an adjacent access point in an activated state, so that the scheduled wake-up period of the first access point does not overlap with the scheduled wake-up period of the adjacent access point in an activated state; The first access point obtains the scheduled wake-up period of the adjacent access point in the activated state, and sets the scheduled wake-up period according to the scheduled wake-up period of the adjacent access point in the activated state. If the scheduled wake-up period set by the first access point can only overlap with a certain adjacent access point, the first access point sends a third The third request message is sent to the neighboring access point, where the third request message includes third scheduled wake-up period information, requesting the neighboring access point to adjust the scheduled wake-up period, wherein the third scheduled wake-up period information is used to indicate the scheduled wake-up period of the first access point.

10. A timed wake-up period negotiation device, characterized in that: The method comprises a negotiation module configured to perform the following steps: Detect whether there is interference on the channel through the terminal; If the interference detected by the terminal meets the first condition and the terminal is a member of the scheduled wake-up period of the first access point, the terminal sends a cooperation request message to the first access point, where the cooperation request message includes an identifier of an interfering basic service set, used to instruct the first access point to negotiate a scheduled wake-up period with a second access point in the interfering basic service set; the cooperation request message also includes first scheduled wake-up period information, used to indicate the scheduled wake-up period that needs to be negotiated.

11. A timed wake-up period negotiation device, characterized in that: The method comprises a negotiation module configured to perform the following steps: The first access point sets a scheduled wake-up period and instructs a neighboring access point to set a scheduled wake-up period based on the scheduled wake-up period of the first access point; or the first access point sets a scheduled wake-up period based on the scheduled wake-up period of the neighboring access point, so that the scheduled wake-up period of the first access point does not overlap with the scheduled wake-up period of the neighboring access point.
