Description

Technical Field

[0001] This utility model relates to the field of polyurethane adhesive preparation, and belongs to an environmentally friendly polyurethane adhesive preparation device. Background Technology

[0002] Environmentally friendly polyurethane adhesives are a new type of adhesive with advantages such as low pollution and high performance. Through optimized formulation and production processes, environmentally friendly polyurethane adhesives significantly reduce VOC emissions, minimizing harm to the environment and human health. Polyurethane adhesives refer to adhesives containing urethane or isocyanate groups in their molecular chains. Polyurethane adhesives are divided into two main categories: polyisocyanates and polyurethanes. Because polyisocyanates contain isocyanate and urethane groups in their molecular chains, polyurethane adhesives exhibit high activity and polarity. They demonstrate excellent chemical adhesion to substrates containing active hydrogen, such as porous materials like foams, plastics, wood, leather, fabrics, paper, and ceramics, as well as smooth-surfaced materials like metals, glass, rubber, and plastics.

[0003] For example, the existing technology disclosure number CN222093007U describes a polyurethane adhesive preparation device. This utility model solves the problem that the stirring blade angle of existing stirring devices is fixed and cannot stir the raw materials in multiple states by adjusting the three angle modes of the stirring blade. It realizes the turning, stirring and discharging of the raw materials, and improves the uniformity and mixing efficiency of the raw material mixture.

[0004] However, the existing technology described above still has the following problems in use: due to the viscous texture of the polyurethane adhesive after stirring, and the small inner diameter of the feeding pipe, the polyurethane adhesive flows slowly within the feeding pipe during feeding, resulting in a slow discharge speed, which affects the processing efficiency of the polyurethane adhesive. Based on this, this utility model provides an environmentally friendly polyurethane adhesive preparation device with a fast feeding speed. Utility Model Content

[0005] Therefore, this utility model provides an environmentally friendly polyurethane adhesive preparation device to solve the problem in the prior art that the polyurethane adhesive is viscous, the inner diameter of the feeding pipe is small, and the polyurethane adhesive flows slowly in the feeding pipe, resulting in slow discharge speed and affecting processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly polyurethane adhesive preparation device includes a preparation tank, a sealing cap fixedly mounted on the top of the preparation tank, a feeding mechanism fixedly mounted on the bottom of the preparation tank, a stirring mechanism inside the preparation tank, and a feeding pipe fixedly mounted on the bottom of the preparation tank and communicating with the inside of the preparation tank. A sealing plug is provided inside the feeding pipe, a vertical rod is fixedly mounted on the bottom of the sealing plug, a guide block is fixedly mounted on the bottom end of the vertical rod, and lifting mechanisms are provided on both sides of the top of the guide block. A support frame is provided on the outside of the preparation tank, and the inner walls on both sides of the support frame are rotatably connected to the preparation tank through ring plates.

[0008] Furthermore, the stirring mechanism includes a stirring paddle, which is positioned above the sealing plug. The top of the stirring paddle passes through the sealing cover and is connected to a variable frequency motor. An installation plate is fixedly fitted onto the outer wall of the variable frequency motor. Two electric push rods are connected between the bottom of the installation plate and the sealing cover. The height of the stirring paddle is automatically adjusted using the electric push rods, making it more time-saving and labor-saving to use.

[0009] Furthermore, the lifting mechanism includes an electric push rod II, the bottom end of the piston rod of the electric push rod II is fixed to the top of the guide block, and an installation block is fixedly sleeved on the outer wall of the electric push rod II. The bottom of the preparation tank has installation grooves on both sides that are adapted to the installation blocks. The installation blocks are inserted into the installation grooves and fixed to the preparation tank. The installation grooves facilitate workers to quickly install the installation blocks, thereby improving the installation efficiency of the electric push rod II.

[0010] Furthermore, a flow guide shroud is fixedly provided on the top of the flow guide block. The flow guide shroud has openings on both the front and rear sides. The flow guide shroud is located between the two electric push rods. The flow guide shroud can prevent polyurethane adhesive from adhering to the electric push rods and affecting their normal extension and retraction.

[0011] Furthermore, the top of the sealing plug is flush with the top of the feed pipe to prevent the polyurethane adhesive in the preparation tank from flowing into the feed pipe.

[0012] Furthermore, a geared motor is fixedly installed on one side of the support frame, and a transmission rod is fixedly installed at one end of the output shaft of the geared motor. One end of the transmission rod passes through the ring plate and is fixed to the outer wall of the preparation tank. The geared motor and the transmission rod work together to facilitate automatic adjustment of the angle of the preparation tank.

[0013] Furthermore, the top of the sealing cap is fixedly perforated with a feed inlet, which is connected to the inside of the preparation tank and is located on the side of the variable frequency motor, for adding raw materials into the preparation tank for preparation.

[0014] Furthermore, the bottom of the support frame is provided with multiple fixing holes, which are evenly distributed on the support frame. In actual use, bolts are passed through the fixing holes to firmly fix the support frame to the ground, thereby improving the stability of the entire device.

[0015] This utility model has the following advantages:

[0016] 1. This utility model uses a stirring mechanism to rotate and stir the raw materials. After stirring, the electric push rod 2 drives the sealing plug to move into the preparation tank, so that the polyurethane adhesive flows out from the gap between the vertical rod and the feeding pipe. Then, the electric push rod 2 drives the sealing plug to move up and down back and forth, and the sealing plug pushes the polyurethane adhesive to prevent the polyurethane adhesive from clogging. This can improve the feeding speed, and the sealing plug can be removed from the feeding pipe to facilitate cleaning the polyurethane adhesive adhering to its surface.

[0017] 2. The preparation tank is driven to rotate by a variable frequency motor and transmission rod. This not only allows the preparation tank to rotate back and forth, causing the polyurethane adhesive raw material to shake and improving the stirring efficiency, but also allows the preparation tank to be inverted for easy cleaning of the inside, making the operation more labor-saving.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Refer to the instruction manual appendix Figures 1-5 This utility model provides an environmentally friendly polyurethane adhesive preparation device, including a preparation tank 1, a sealing cap 2 fixedly provided on the top of the preparation tank 1, and a feeding mechanism 3 fixedly provided on the bottom of the preparation tank 1. Specifically, the feeding mechanism 3 includes a feeding pipe 31 fixedly provided on the bottom of the preparation tank 1, and the feeding pipe 31 is connected to the inside of the preparation tank 1. A sealing plug 32 is provided inside the feeding pipe 31, the top of the sealing plug 32 is flush with the top of the feeding pipe 31, a vertical rod 33 is fixedly provided on the bottom of the sealing plug 32, a guide block 34 is fixedly provided at the bottom end of the vertical rod 33, and a lifting mechanism 5 is provided on both sides of the top of the guide block 34.

[0031] In one example, the lifting mechanism 5 includes an electric push rod 51. The bottom end of the piston rod of the electric push rod 51 is fixed to the top of the guide block 34. An installation block 52 is fixedly sleeved on the outer wall of the electric push rod 51. An installation groove 53 adapted to the installation block 52 is opened on both sides of the bottom of the preparation tank 1. The installation block 52 is inserted into the installation groove 53 and fixed to the preparation tank 1.

[0032] like Figure 3As shown, a stirring mechanism 4 is also provided inside the preparation tank 1. Specifically, the stirring mechanism 4 includes a stirring paddle 41, which is located above the sealing plug 32. The top of the stirring paddle 41 passes through the sealing cover 2 and is connected to a variable frequency motor 42. An installation plate 43 is fixedly sleeved on the outer wall of the variable frequency motor 42. Two electric push rods 44 are connected between the bottom of the installation plate 43 and the sealing cover 2.

[0033] The preparation tank 1 is provided with a support frame 6 on the outside. The inner walls on both sides of the support frame 6 are rotatably connected to the preparation tank 1 through ring plates 7.

[0034] In actual use, the polyurethane adhesive raw material is conveyed into the preparation tank 1 through the feed inlet 12. Then, the variable frequency motor 42 drives the stirring paddle 41 to rotate and stir the raw material. During the stirring process, the speed of the variable frequency motor 42 can be adjusted by changing the power supply frequency, thereby adjusting the speed of the stirring paddle 41. After stirring is completed, the electric push rod 44 is extended to drive the variable frequency motor 42 on the mounting plate 43 to move upward. The upward movement of the variable frequency motor 42 simultaneously drives the stirring paddle 41 to move upward a distance. Then, the electric push rod 51 is shortened to drive the guide block 34, the vertical rod 33 on the guide block 34, and the sealing plug 32 to move upward into the preparation tank 1, so that the polyurethane adhesive flows out from the gap between the vertical rod 33 and the feed pipe 31. During the feeding process, the electric push rod 51 drives the sealing plug 32 to move up and down reciprocally. When the sealing plug 32 moves downward, it can push the polyurethane adhesive to prevent the polyurethane adhesive from clogging, thereby improving the feeding speed.

[0035] In this embodiment, a flow guide shroud 8 is also fixedly provided on the top of the flow guide block 34. The flow guide shroud 8 has openings 9 on both the front and rear sides. The flow guide shroud 8 is located between the two electric push rods 51. Through the cooperation of the flow guide shroud 8 and the flow guide block 34, the polyurethane adhesive can flow out from the two openings 9, avoiding the polyurethane adhesive from adhering to the electric push rods 51.

[0036] Refer to the instruction manual appendix Figures 1-5 A reduction motor 10 is fixedly installed on one side of the support frame 6. A transmission rod 11 is fixedly installed at one end of the output shaft of the reduction motor 10. One end of the transmission rod 11 passes through the ring plate 7 and is fixed to the outer wall of the preparation tank 1. A fixing hole 13 is opened at the bottom of the support frame 6. There are multiple fixing holes 13, which are evenly distributed on the support frame 6.

[0037] The preparation tank 1 is driven to reciprocate within the support frame 6 by the servo frequency conversion motor 42 and the transmission rod 11. This causes the polyurethane adhesive raw material inside the preparation tank 1 to shake, thereby improving the stirring efficiency of the raw material to a certain extent. At the same time, it can also drive the preparation tank 1 to be inverted, making it easier for the staff to remove the sealing cover 2. After the sealing cover 2 is separated from the preparation tank 1, the preparation tank 1 is driven to rotate again, so that the round opening of the preparation tank 1 moves upward (for example, the preparation tank 1 is rotated to 90 degrees), which makes it easier for the staff to clean the inside of the preparation tank 1.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
