Description

A PU adhesive mixing tank Technical Field

[0001] This utility model relates to the field of PU adhesive production technology, specifically a PU adhesive mixing tank. Background Technology

[0002] PU adhesive, or polyurethane adhesive, is a widely used adhesive for bonding various materials. It has good bonding strength, heat and weather resistance, and is environmentally friendly and non-toxic. In the production process of PU adhesive, it is necessary to stir in a mixing tank to promote the mixing of adhesive and filler.

[0003] Existing patent application number: 202320823116.X A prepreg tank stirring device includes a prepreg tank and a pneumatic motor. A roller is assembled on the top inside of the prepreg tank, a stirring shaft is rotatably installed on the bottom inside of the prepreg tank, and a speed reducer is assembled with the stirring shaft on the outside of one end of the prepreg tank.

[0004] The aforementioned patent describes a functional structure of a mixing tank. In actual use, the fluidity of the adhesive inside the mixing tank is poor. The stirring shaft can only stir the adhesive but cannot promote the flow of the adhesive within the tank, resulting in uneven distribution of the adhesive components within the tank. A longer stirring time is required to achieve the desired mixing effect. Its structural function needs further improvement. Therefore, we propose a PU adhesive mixing tank to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a PU adhesive mixing tank to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a PU adhesive mixing tank, comprising a mixing tank, a feed inlet, a discharge outlet, a motor, a mixing paddle, and a flow guiding device. The top of the mixing tank has a feed inlet, and the rear of the mixing tank has a discharge outlet. A motor is installed at the front of the mixing tank, and a mixing paddle is rotatably mounted inside the mixing tank. The front shaft of the mixing paddle is connected to the motor via a transmission connection. A flow guiding device is provided at the bottom of the mixing tank, comprising a connecting frame, locking holes, and a support. The connecting frame is equidistantly welded at the four corners of the bottom of the mixing tank, and a locking hole is provided through the surface of the connecting frame. A support is provided below the mixing tank, and a groove is provided on the top surface of the support. The mixing tank is placed inside the groove. The support has equidistant insertion interfaces at the corners, and the connecting frame is longitudinally inserted into the inner side of the insertion interface. A base is provided below the support, and a hinge seat is installed in the middle of the top surface of the base. The hinge seat is hinged to the middle of the bottom surface of the support. An electric push rod is hinged to the rear of the top surface of the base. The top telescopic end of the electric push rod is hinged to the support. Connecting cavities are horizontally arranged inside the left and right sides of the support. The connecting cavities horizontally pass through the inner side of the insertion interface. A two-way lock is installed in the middle of the inner side of the connecting cavity. The two-way lock has telescopic locking tongues at both the front and rear. The locking tongues slide along the inner side of the connecting cavity and horizontally pass through the inner side of the lock hole to lock and fix the connecting frame and the insertion interface. A knob is rotatably installed in the middle of the left and right side walls of the support. The knob is connected to the lock cylinder of the two-way lock.

[0007] Preferably, the height of the connecting frame is ≥30cm.

[0008] Preferably, the groove matches the shape and size of the bottom of the mixing tank, and the groove has the same length as the mixing tank.

[0009] Preferably, the inner wall of the bracket is covered with a cushioning pad.

[0010] Preferably, anti-collision strips are symmetrically arranged at both ends of the top surface of the base, and the thickness of the anti-collision strips is not less than 2cm.

[0011] Preferably, the rotation angle range of the support is ≥30°.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention provides a flow guiding device at the bottom of the mixing tank. By activating an electric push rod to perform a telescopic action, the support is controlled to tilt back and forth, providing a flow guiding angle for the mixing tank. This allows the adhesive material inside the mixing tank to flow towards the tilted end, thereby circulating the adhesive material at both ends inside the mixing tank. This ensures that the adhesive components are evenly distributed, thus improving the mixing effect of the mixing tank.

[0014] This invention features a two-way locking device located in the middle of the inner side of the connecting cavity. By turning the knob to switch the two-way locking device to the retracted state, the connection between the connecting frame and the support can be released, allowing the mixing tank to be disassembled and removed from the tray. The connecting frame not only serves as a connecting accessory between the mixing tank and the support, but also acts as a foot support for the mixing tank after it is removed, enabling the mixing tank to be used independently and providing greater flexibility.

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please refer to Figures 1 and 3. This utility model provides a PU adhesive mixing tank, including a mixing tank 1, a feed inlet 2, a discharge outlet 3, a motor 4, a stirring paddle 5, and a flow guiding device 6. The mixing tank 1 has a feed inlet 2 at the top and a discharge outlet 3 at the rear. The motor 4 is installed at the front of the mixing tank 1, and the stirring paddle 5 is rotatably installed inside the mixing tank 1. The front shaft of the stirring paddle 5 is connected to the motor 4 for transmission. The flow guiding device 6 is provided at the bottom of the mixing tank 1.

[0024] Specifically, during use, the rubber material is put into the mixing tank 1 through the feed port 2, then the motor 4 is started to drive the mixing paddle 5 to stir and mix the rubber material, and finally the discharge port 3 is opened to discharge the mixed rubber material, thus completing the mixing process.

[0025] Please refer to Figures 2, 4, and 5. This utility model provides a PU adhesive mixing tank. The flow guiding device 6 includes a connecting frame 61, a locking hole 62, and a support 63. The connecting frame 61 is welded at equal intervals at the four corners of the bottom of the mixing tank 1. The height of the connecting frame 61 is ≥30cm, so that the connecting frame 61 can not only serve as a connecting accessory between the mixing tank 1 and the support 63, but also serve as a foot support on the ground after the mixing tank 1 is removed, supporting the mixing tank 1 for independent use and providing greater flexibility. The locking hole 62 is provided through the surface of the connecting frame 61. The support 63 is provided below the mixing tank 1. The top surface of the support 63 has a groove 64. The mixing tank 1 is placed inside the groove 64. The shape and size of the groove 64 match the bottom of the mixing tank 1, and the length of the groove 64 is the same as that of the mixing tank 1, ensuring that the groove 64 can provide stable support for the mixing tank 1. The inner wall of the groove 64 is lined with a cushioning rubber pad. The groove 64 passes through... The buffer pad makes flexible contact with the mixing tank 1 to avoid friction and noise. The four corners of the inner side of the support 64 are provided with insertion interfaces 65 at equal intervals. The connecting frame 61 is longitudinally inserted into the inner side of the insertion interface 65 to restrict the movement of the mixing tank 1 and prevent the mixing tank 1 from sliding off the support 64. The support 63 is provided with a base 66. The top surface of the base 66 is symmetrically provided with anti-collision rubber strips at both ends. The thickness of the anti-collision rubber strips is not less than 2cm. The anti-collision rubber strips play an anti-collision protection role to prevent the support 63 from directly contacting and colliding with the base 66 to avoid noise. The top surface of the base 66 is provided with a hinge seat 67. The hinge seat 67 is hinged to the bottom surface of the support 63. The rotation angle range of the support 63 is ≥30°, so that the support 63 can provide a sufficient guiding angle for the mixing tank 1. The rear top surface of the base 66 is hinged with an electric push rod 68. The top telescopic end of the electric push rod 68 is hinged to the support 63.

[0026] Specifically, during the operation of the mixing tank 1, the electric push rod 68 is activated to perform a telescopic action to control the support 63 to tilt back and forth, thereby providing a guiding angle for the mixing tank 1, so that the rubber material inside the mixing tank 1 flows to the tilted end, thereby circulating the rubber material at both ends inside the mixing tank 1, ensuring that the rubber material components can be evenly distributed, and improving the mixing effect of the mixing tank 1.

[0027] Please refer to Figure 6. This utility model provides a PU adhesive mixing tank. The support 63 has horizontally arranged connecting cavities 69 on both sides. The connecting cavities 69 horizontally pass through the inside of the insertion interface 65. A two-way lock 610 is installed in the middle of the inner side of the connecting cavity 69. The two-way lock 610 has a locking tongue 611 that is telescopically arranged at both the front and rear. The locking tongue 611 slides along the inner side of the connecting cavity 69 and horizontally inserts through the inner side of the lock hole 62, thereby locking and fixing the connecting frame 61 and the insertion interface 65. A knob 612 is rotatably installed in the middle of the left and right side walls of the support 63. The knob 612 establishes a transmission connection with the lock cylinder of the two-way lock 610, and the knob 612 controls the two-way lock 610 to perform telescopic movement.

[0028] Specifically, when it is necessary to disassemble the mixing tank 1, turn the knob 612 to switch the two-way lock 610 to the retracted state. At this time, the locking tongue 611 disengages from the locking hole 62 and retracts along the inside of the connecting cavity 69 to release the installation connection between the connecting frame 61 and the support 63. The mixing tank 1 can then be disassembled and removed from the tray 64. The connecting frame 61 not only serves as a connecting accessory between the mixing tank 1 and the support 63, but also acts as a foot support on the ground after the mixing tank 1 is removed, supporting the mixing tank 1 for independent use and providing greater flexibility.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
