Description

Technical Field

[0001] The utility model relates to the technical field of foam machines, in particular to an energy-saving foam machine for producing polyurethane sandwich insulation boards. Background Technique

[0002] The foam machine for processing polyurethane sandwich insulation boards, also known as a foam generator, is a device that makes foam from an aqueous solution with a certain concentration of foaming agent. The storage tank of the foam machine is used in cooperation with the foam machine. The installation platform of the existing storage tank is generally supported by brackets, but the fixing effect of this kind of bracket on the storage tank is poor, and it cannot meet the use of storage tanks of different models.

[0003] In order to solve the above problems, Patent CN201922477785.2 discloses a high-pressure foam machine storage tank structure for processing polyurethane insulation boards, including a support platform, a storage tank body, support columns and threaded rods. Universal wheels are fixedly installed at the four corners of the bottom end face of the support platform through bolts, and locking pieces are provided on all four groups of universal wheels. A base is arranged at the middle position of the top end face of the support platform. Ear plates are fixedly welded to the bottoms of both sides of the base, and both groups of ear plates are threadedly penetrated through the support platform by bolts. A storage tank body for a high-pressure foam machine is vertically arranged on the top end face of the base. A top cover is fixedly installed on the top end face of the storage tank body through bolts. A feed pipe and a pressure gauge are respectively arranged on the top end face of the top cover. Support columns are symmetrically and vertically arranged on both sides of the storage tank body on the top end face of the support platform. This high-pressure foam machine storage tank structure for processing polyurethane insulation boards is not only convenient for fixing the storage tank body, but also meets the use of storage tank bodies of different models.

[0004] However, we found that this structure has the following defects and deficiencies: the foaming agent is easy to adhere to the inner wall of the barrel during foaming, resulting in incomplete discharge and waste. At the same time, the fixing of the barrel makes it difficult to clean the inside of the barrel later, which is not convenient for later maintenance. Therefore, we propose an energy-saving foam machine for producing polyurethane sandwich insulation boards. Content of the Utility Model

[0017] Beneficial effects

[0018] The utility model provides an energy-saving foaming machine for producing polyurethane sandwich insulation panels. Compared with the prior art, the following beneficial effects are achieved:

[0019] 1. The energy-saving foaming machine for producing polyurethane sandwich insulation boards has a tank body rotatably installed on a U-shaped frame through a first rotating rod. A driving mechanism is installed on the U-shaped frame to drive the tank body to rotate. First arc-shaped baffles and second arc-shaped baffles are installed on the inner wall of the tank body. A stirring mechanism is arranged inside the tank body, so that the foaming agent in the tank body can be stirred by the stirring mechanism to accelerate the foaming rate of the foaming machine. At the same time, the rotation of the tank body itself can make the foaming agent inside the tank body move relative to the inner wall of the tank body. The first arc-shaped baffle and the second arc-shaped baffle are used to block the foaming agent, so that there is a fluid impact force between the foaming agent and the inner wall of the tank body. Thus, the fluid impact force can be used to reduce the adhesion of the foaming agent to the inner wall of the tank body, reduce the waste of resources during discharging, and be more energy-saving.

The rotating assembly includes a second rotating rod, a bearing seat, etc. By manually turning the handle to drive the second rotating rod to rotate, the tank body can be driven to rotate. Thus, it is convenient to pour the foaming agent inside the tank body outwards through the rotation of the tank body. At the same time, the rotation of the tank body can be utilized to replace the traditional fixed structure, making it more convenient for workers to clean the inner wall of the tank body during rotation and facilitating later cleaning and maintenance.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-3, the utility model provides two technical solutions:

[0027] Embodiment 1:

[0028] An energy-saving foaming machine for producing polyurethane sandwich insulation boards comprises two frames 1, a shaped frame 2 is arranged inside the two frames 1, and a tank body 3 is rotatably mounted on the shaped frame 2;

[0029] Both ends of the shaped frame 2 are rotatably mounted on the frame 1 through a rotating assembly 5;

[0030] The bottom of the tank body 3 is connected with a first rotating rod 4, and the first rotating rod 4 is rotatably mounted on the shaped frame 2 through a bearing;

[0031] A stirring mechanism 6 is installed on the flank 2 for stirring inside the tank 3;

[0032] A first arc-shaped retaining strip 7 is installed on the inner bottom wall of the tank body 3, and a second arc-shaped retaining strip 8 is installed on the inner side wall of the tank body 3;

[0033] A driving mechanism 9 is installed on the shaped frame 2 to drive the tank body 3 to rotate.

[0034] Embodiment 2:

[0035] The main difference from the first embodiment is:

[0036] An energy-saving foaming machine for the production of polyurethane sandwich insulation panels. The rotating assembly 5 includes a second rotating rod 51 fixed at both ends of the U-shaped frame 2 and a bearing seat 52 installed on the machine frame 1. The second rotating rod 51 is rotatably installed on the bearing seat 52. A handle 53 is installed on one of the second rotating rods 51. Manually turning the handle 53 to drive the rotation of the second rotating rod 51 can drive the tank body 3 to rotate; The stirring mechanism 6 includes a first motor 61 fixed at the bottom of the U-shaped frame 2. The output end of the first motor 61 is installed with a rotating shaft 62 that penetrates through the first rotating rod 4 and the tank body 3 and extends into the interior of the tank body 3. Stirring rods 63 are fixed on the rotating shaft 62. Starting the first motor 61 to drive the rotation of the rotating shaft 62 can drive the rotation of the stirring rods 63. Through the stirring rods 63, the foaming agent in the tank body 3 can be stirred to accelerate the foaming rate of the foaming machine; The number of the first arc-shaped strips 7 and the second arc-shaped strips 8 are respectively set to be multiple. The first arc-shaped strips 7 are circumferentially distributed at equal angles on the inner bottom wall of the tank body 3, and the second arc-shaped strips 8 are circumferentially distributed at equal angles on the inner side wall of the tank body 3. The rotation of the tank body 3 itself can make the relative movement between the foaming agent inside the tank body 3 and the inner wall of the tank body 3. By using the first arc-shaped strips 7 and the second arc-shaped strips 8 to block the foaming agent, a fluid impact force is generated between the foaming agent and the inner wall of the tank body 3, so that the adhesion of the foaming agent to the inner wall of the tank body 3 can be reduced by using the fluid impact force; The driving mechanism 9 includes a driven gear 91 fixed on the outer peripheral wall of the tank body 3 and a second motor 92 fixed on the U-shaped frame 2. A driving gear 93 is installed on the output shaft of the second motor 92. A transmission chain 94 is传动连接 between the driving gear 93 and the outer circumference of the driven gear 91. Starting the second motor 92 to drive the rotation of the driving gear 93 can drive the rotation of the transmission chain 94 and then drive the rotation of the driven gear 91, thereby driving the rotation of the tank body 3; A cover plate is arranged on the top of the tank body 3. The cover plate is hinged and installed on the tank body 3 through a hinge. It is convenient to add and clean the foaming agent into the tank body 3 through the cover plate.

[0037] It should be noted that there is an unclear expression "传动连接" in the original text. I have translated it as "传动连接" for now. You may need to check and correct it according to the actual situation.When the energy-saving foaming machine for producing polyurethane sandwich insulation panels is in use, the tank body 3 is rotatably installed on the U-shaped frame 2 through the first rotating rod 4. A driving mechanism 9 is installed on the U-shaped frame 2 to drive the tank body 3 to rotate. The inner wall of the tank body 3 is provided with a first arc-shaped baffle 7 and a second arc-shaped baffle 8. A stirring mechanism 6 is arranged in the tank body 3. Thus, the stirring mechanism 6 can stir the foaming agent in the tank body 3 to accelerate the foaming rate of the foaming machine. At the same time, the rotation of the tank body 3 itself can make the foaming agent inside the tank body 3 move relative to the inner wall of the tank body 3. The first arc-shaped baffle 7 and the second arc-shaped baffle 8 are used to block the foaming agent, so that there is a fluid impact force between the foaming agent and the inner wall of the tank body 3. Thus, the fluid impact force can be used to reduce the adhesion of the foaming agent to the inner wall of the tank body 3, reduce the waste of resources during discharging, and be more energy-saving. In addition, the tank body 3 of the present utility model is rotatably installed on the frame 1 through the rotating assembly 5. The rotating assembly 5 includes a second rotating rod 51, a bearing seat 52, etc. By manually turning the handle 53 to drive the second rotating rod 51 to rotate, the tank body 3 can be driven to rotate. Thus, the rotation of the tank body 3 facilitates the pouring of the foaming agent inside the tank body 3 outwards. At the same time, the tank body 3 can rotate, replacing the traditional fixed structure, making it more convenient for the staff to clean the inner wall of the tank body 3 during rotation and facilitating the later cleaning and maintenance.
