Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to heating equipment for producing polyurethane sealing glue. Background Art

[0002] Polyurethane sealants are mainly composed of polyurethane rubber and polyurethane prepolymers. This type of sealant has been widely used in many fields due to its excellent tensile strength, elasticity, wear resistance, oil resistance and cold resistance. However, its water resistance and alkaline water resistance are relatively weak, so special attention should be paid in practical applications. Polyurethane sealants can be divided into heat vulcanization type, room temperature vulcanization type and hot melt type according to their vulcanization method. Among them, the room temperature vulcanization type is further divided into single component and two components. This kind of sealant plays an important role in the sealing of joints in buildings, squares and roads, as well as in automobile manufacturing, glass installation, electronic filling, submarines and rockets.

[0003] In the production and processing of polyurethane sealants, the heating device plays a vital role in heating and stirring the glue raw materials. However, when heating the glue, the traditional heating device usually only relies on the motor to drive the stirring mechanism to rotate in a single circumferential direction. This method is not effective when dealing with glue with a dense texture. Since the mixing speed of the outer and inner layers of glue is slow, the heat conduction efficiency is also reduced, resulting in the heating process of the polyurethane sealant becoming slow and difficult to meet production needs. Therefore, a heating device for the production of polyurethane sealant is proposed. Summary of the invention

[0006] Preferably, a support frame is sleeved on the outside of the rack, and the outer side of the support frame is sleeved on the outside of the shaft seat.

[0007] Preferably, the bottom end of the connecting shaft column is movably connected to a third bevel gear via a bearing, the third bevel gears are meshed with the second bevel gears, and a lower shaft body is installed at the bottom of the second bevel gears.

[0008] Preferably, connecting rods are fixedly installed on the outer circumference of the upper shaft body and the lower shaft body, the number of the connecting rods is 3-5 groups, and the outer sides of the bottoms of the connecting rods are fixedly connected with mixing blades.

[0009] Preferably, sliding grooves are provided on both the front and rear sides of the top of the base plate, sliding blocks are inserted into the sliding grooves, and the top ends of the sliding blocks are fixedly connected to the bottom of the heating chamber, and hinged plates are connected to both the front and rear sides of the heating chamber.

[0012] Compared with the prior art, the utility model provides a heating device for producing polyurethane sealing glue, which has the following beneficial effects:

[0013] 1. The heating equipment for the production of polyurethane sealing glue cleverly uses the power of the rotating motor, and further drives the gear to rotate through the transmission of the linkage rod and the rack, so that the upper shaft and the first bevel gear begin to rotate. This transmission method further triggers the linkage of the second bevel gear and the third bevel gear, thereby realizing the simultaneous rotation of the connecting rod and the mixing blade, and their rotation directions are opposite. This design greatly improves the mixing rate of glue, speeds up the heat conduction efficiency between the inner and outer layers of glue, and significantly improves the speed of glue heating.

[0014] 2. The heating equipment for the production of polyurethane sealing glue is also equipped with a transmission motor, which drives the rotation of the hinged connecting rod, and then uses the function of the connecting block to drive the motion frame and the hinged plate to move back and forth. This movement mode then causes the left and right shaking of the heating chamber, which not only enhances the uniformity of glue mixing, but also effectively avoids the agglomeration problem that may occur due to overheating of the outer layer of glue, further improving the overall quality and effect of glue heating.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a technical solution, a heating device for producing polyurethane sealing glue, including a base plate 1, a heating chamber 2, a connecting plate 3, a rotating motor 4, a linkage rod body 5, a rack 6, a support frame 7, a shaft seat 8, a gear 9, an upper shaft body 10, a first bevel gear 11, a connecting shaft column 12, a second bevel gear 13, a third bevel gear 14, a lower shaft body 15, a connecting rod 16, a mixing blade 17, a sliding groove 18, a sliding block 19, a mounting frame 20, a hinged plate 21, a transmission motor 22, a moving frame 23, a connecting block 24 and a hinged connecting rod 25, please refer to Figure 1 A heating chamber 2 is installed on the top of the base plate 1, and the upper left side of the heating chamber 2 is connected to the connecting plate 3. A rotating motor 4 (such as Figure 2 The rotor of the rotary motor 4 is directly connected to the linkage rod 5, and the end of the linkage rod 5 is movably connected to the rack 6 through a bearing.

[0023] The front lower part of the connecting plate 3 is provided with a shaft seat 8 (such as Figure 3As shown). The lower part of the shaft seat 8 is coaxially fixed with the gear 9, and the bottom of the gear 9 is connected to the upper shaft body 10. The end of the upper shaft body 10 is provided with a first bevel gear 11, which is installed on the connecting shaft column 12 through a bearing. The left and right sides of the connecting shaft column 12 are movably connected to the second bevel gear 13 through a rotating shaft, and the two second bevel gears 13 are meshed with the first bevel gear 11.

[0024] A support frame 7 is installed on the outside of the rack 6. The four sides of the support frame 7 are tightly attached to the outside of the shaft seat 8, which plays a good supporting and positioning role.

[0025] The bottom of the connecting shaft column 12 is connected to a third bevel gear 14 through a bearing, and the third bevel gear 14 forms a meshing relationship with the second bevel gear 13. The bottom of the second bevel gear 13 is equipped with a lower shaft body 15 to ensure effective transmission of power.

[0026] 3 to 5 groups of connecting rods 16 are fixedly installed on the outer sides of the upper shaft 10 and the lower shaft 15, and the bottoms of these connecting rods 16 are connected to mixing blades 17. When the rotary motor 4 is started, it will drive the movement of the linkage rod 5 and the rack 6, and then drive the rotation of the upper shaft 10 and the first bevel gear 11 through the gear 9. This rotation will be further transmitted to the third bevel gear 14 through the second bevel gear 13, causing the connecting rod 16 and the mixing blade 17 to start rotating. It is worth noting that the rotation directions of these blades are opposite. This design greatly improves the speed of glue mixing, and also speeds up the heat conduction rate between the outer and inner layers of glue, thereby significantly improving the efficiency of glue heating.

[0027] See also Figure 4 The top and rear sides of the base plate 1 are designed with sliding grooves 18, and sliding blocks 19 are inserted into the sliding grooves 18. The top of the sliding block 19 is firmly connected to the bottom of the heating chamber 2. In order to enhance the stability and flexibility of the heating chamber 2, hinge plates 21 are provided on the front and rear sides.

[0028] The right sides of these hinged plates 21 are cleverly covered with mounting frames 20, and the bottoms of the mounting frames 20 are firmly fixed to the corresponding positions of the base plate 1. Figure 5 As shown, a motion frame 23 is mounted on the right end of the hinge plate 21, which will play a key role in the subsequent motion.

[0029] Transmission motors 22 are installed at the front and rear of the right side of the base plate 1. The rotors of these transmission motors 22 are coaxially connected with the hinged connecting rods 25, and the outer ends of the hinged connecting rods 25 are movably connected with the connecting blocks 24 through bearings. These connecting blocks 24 are movably inserted into the interior of the motion frame 23 to form a flexible motion system.

[0030] When the transmission motor 22 is started, it drives the hinged connecting rod 25 to rotate, and then pushes the motion frame 23 and the hinge plate 21 to reciprocate left and right through the connecting block 24. This motion mechanism enables the heating chamber 2 to swing left and right, effectively promoting the mixing uniformity of the glue during the heating process and improving the quality of the glue heating. At the same time, this shaking also avoids the agglomeration of the outer layer of glue due to overheating, ensuring the smooth progress of the glue heating process.

[0031] Working principle of this device:

[0032] First, the rotary motor 4 is started, which drives the linkage rod 5 and the rack 6 to move. This action is further transmitted through the gear 9, causing the upper shaft 10 and the first bevel gear 11 to start rotating. Then, the rotation of the first bevel gear 11 drives the second bevel gear 13 meshing with it, and then the third bevel gear 14 also starts to rotate. In this process, the connecting rod 16 and the mixing blade 17 rotate at the same time, and their rotation directions are opposite. This counter-rotation design significantly improves the efficiency of glue mixing, and at the same time accelerates the heat conduction between the outer and inner layers of glue, thereby accelerating the heating process of the glue.

[0033] Next, the transmission motor 22 is started, which drives the hinge connecting rod 25 to rotate. Through the transmission of the connecting block 24, the motion frame 23 and the hinge plate 21 will reciprocate left and right. This motion mechanism enables the heating chamber 2 to shake left and right, thereby enhancing the mixing uniformity of the glue during the heating process. This shaking not only avoids the problem of the outer layer of glue agglomerating due to overheating, but also further improves the overall quality of glue heating.
