Description

Technical Field

[0001] This utility model belongs to the field of adhesive formulation technology, and in particular relates to an apparatus for preparing flame-retardant adhesives. Background Technology

[0002] In the production and formulation of flame-retardant adhesives, the uniformity of mixing directly affects the flame-retardant performance, and it is necessary to ensure that the flame-retardant components are evenly distributed in the adhesive. However, existing formulation equipment has the following problems: Existing preparation devices have poor adaptability. The support plate height is fixed and cannot be compatible with material buckets of different heights. When changing material buckets, the overall structure of the device needs to be adjusted, which is cumbersome and inefficient. Moreover, the position of the stirring rod is fixed, making it difficult to adapt to the dynamic changes in the liquid level during the preparation of the adhesive. When the liquid level changes, the stirring range cannot be adjusted in time, resulting in a decrease in stirring effect and an inability to maintain the optimal mixing state. Therefore, we propose a flame-retardant adhesive preparation device. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing a flame-retardant adhesive preparation device that allows for adaptive adjustment of the mixing process based on the height of the container.

[0004] In view of this, the present invention provides a flame-retardant adhesive preparation device, including a base, a fixed frame welded to one side of the upper end of the base, a support plate provided at the upper end of the fixed frame, sliding sleeves provided on both the front and rear sides of the support plate, a lifting assembly, the lifting assembly including a self-locking motor provided at the upper end of the fixed frame, a lead screw installed at the drive end of the self-locking motor, a lead screw sleeve fixedly installed on the side of the support plate near the lead screw, the lower end of the lead screw being rotatably connected to the upper end of the base via a bearing, a position sensor detachably installed on the lower end of the support plate away from the lead screw, and an adjustment assembly, the adjustment assembly including a rotary motor provided on the support plate, a transmission rod installed at the drive end of the rotary motor, a stirring rod detachably installed at the lower end of the transmission rod, two rotary motors symmetrically arranged, a support frame provided on one side of the rotary motor, an electric cylinder provided at the upper end of the support frame, and the output end of the electric cylinder being detachably connected to the upper end of the rotary motor.

[0005] Furthermore, the support plate is disposed in the middle of the fixed frame, and the support plate is movably connected to the fixed frame.

[0006] Furthermore, the size of the sliding sleeve is adapted to the size of the fixed frame, and the sliding sleeve is slidably connected to the fixed frame.

[0007] Furthermore, the two stirring rods are symmetrically arranged below the support plate, and four stirring frames are arranged on the outer side of the stirring rods. The upper and lower sides of the stirring frames are parallel, the sides are twisted, and the inside of the frames is hollow.

[0008] Furthermore, the two ends of the sliding sleeve are fixedly connected to the two sides of the support plate, and the top side profile of the sliding sleeve is triangular.

[0009] Furthermore, the size of the lead screw is adapted to the size of the lead screw sleeve, and the lead screw and the lead screw sleeve are threadedly connected.

[0010] Furthermore, the lower end of the support frame is detachably connected to the support plate by bolts, and the upper end of the electric cylinder is detachably connected to the upper end of the support frame.

[0011] Furthermore, the base has a ramp on the side away from the fixed frame, and the ramp is located below the support plate.

[0012] The beneficial effects of this utility model are: It can both raise and lower the support plate, thus enabling the device to be compatible with material buckets of different heights and specifications. At the same time, the position sensor can monitor the descent position of the support plate in real time, effectively avoiding component collisions or material bucket damage caused by excessive movement.

[0013] Furthermore, the symmetrical rotating motor enables the two stirring rods to simultaneously agitate the rubber compound in the bucket from both sides. Compared to a single stirring structure, this significantly enhances the convection and mixing of the rubber compound, effectively avoids dead zones in the mixing, improves the uniformity of the rubber compound mixing, and ensures that the flame retardant components are evenly distributed in the rubber compound.

[0014] The position of the rotary motor can be flexibly adjusted by the cooperation of the electric cylinder and the support frame, thereby changing the staggered state of the stirring rods. The stirring range can be adjusted in real time according to the changes in the liquid level in the barrel, always maintaining the best stirring effect, thus making it suitable for situations where the liquid level changes dynamically during the preparation of rubber compounds.

[0021] Reference Figures 1 to 5 A flame-retardant adhesive preparation device includes a base 1, a fixed frame 11 welded to one side of the upper end of the base 1, a support plate 12 provided at the upper end of the fixed frame 11, sliding sleeves 13 provided on both the front and rear sides of the support plate 12, and a lifting assembly. The lifting assembly includes a self-locking motor 2 located at the upper end of the fixed frame 11, a lead screw 21 mounted on the drive end of the self-locking motor 2, a lead screw sleeve 22 fixedly mounted on the side of the support plate 12 near the lead screw 21, and the lower end of the lead screw 21 rotatably connected to the upper end of the base 1 via a bearing. A position sensor 23 is detachably installed on the side of the lower end away from the lead screw 21. An adjustment assembly is also installed, which includes a rotary motor 3 mounted on the support plate 12. A transmission rod 31 is mounted on the drive end of the rotary motor 3. A stirring rod 32 is detachably mounted on the lower end of the transmission rod 31. Two rotary motors 3 are provided and are symmetrically arranged. A support frame 33 is provided on one side of the rotary motor 3. An electric cylinder 34 is provided on the upper end of the support frame 33. The output end of the electric cylinder 34 is detachably connected to the upper end of the rotary motor 3.

[0022] When adapting to material buckets of different heights, this application activates the self-locking motor 2 at the upper end of the fixing frame 11. The output of the self-locking motor 2 drives the lead screw 21 to rotate around the bearing at the upper end of the base 1. Since the lead screw sleeve 22 on one side of the support plate 12 forms a threaded engagement with the lead screw 21, the rotational motion of the lead screw 21 is converted into the linear motion of the lead screw sleeve 22, thereby driving the support plate 12 to move up and down along the fixing frame 11. During this process, the position sensor 23 at the lower end of the support plate 12 collects the distance data between itself and the material bucket or the base 1 in real time. When the preset safe position is reached, the sensor sends a signal to control the self-locking motor 2 to stop. To stop the operation and prevent excessive movement of the support plate 12, two symmetrically arranged rotary motors 3 drive their respective transmission rods 31 and lower stirring rods 32 to rotate at high speed, stirring the rubber material in the barrel in both directions. When the liquid level of the rubber material in the barrel changes, the electric cylinder 34 at the upper end of the support frame 33 is activated, and its output end pushes or pulls the rotary motor 3 to move laterally along the support plate 12. By adjusting the relative position of the two rotary motors 3, the staggered position and stirring area of ​​the stirring rods 32 are changed to ensure that the stirring rods 32 are always at the optimal stirring depth, so as to achieve full mixing of rubber materials at different liquid levels.

[0023] In the example of this application, the support plate 12 is disposed in the middle of the fixed frame 11, and the support plate 12 is movably connected to the fixed frame 11.

[0024] As a preferred example of this utility model, when the lifting assembly drives the support plate 12 to move, the support plate 12 drives the rotary motor 3 and the stirring rod 32 mounted above to move accordingly, thereby making preparations suitable for material buckets of different heights.

[0025] In the example of this application, the size of the sliding sleeve 13 is adapted to the size of the fixed frame 11, and the sliding sleeve 13 is slidably connected to the fixed frame 11.

[0026] As a preferred example of this utility model, when the support plate 12 moves under the drive of the lifting assembly, the sliding sleeve 13 slides synchronously along the fixed frame 11, thereby limiting the horizontal displacement of the support plate 12 and ensuring the stability and efficiency of the lifting process.

[0027] In the example of this application, two stirring rods 32 are symmetrically arranged below the support plate 12. Four stirring frames are arranged on the outer side of the stirring rods 32. The upper and lower sides of the stirring frames are parallel, the sides are twisted, and the inside of the frames is hollow.

[0028] As a preferred example of this utility model, when the rotary motor 3 drives the stirring rod 32 to rotate, the two stirring rods 32 on both sides cut into the rubber material from different areas of the material barrel, forming a stirring flow in the same direction. The staggered structure causes the stirring flows on both sides to converge in the middle of the material barrel, breaking the unidirectional flow field formed by a single stirring rod 32, and causing the rubber material to form complex convection and vortex motion, covering all corners of the material barrel. When the four twisted stirring frames on the outside of the stirring rod 32 rotate with the stirring rod 32, they not only drive more rubber material to move by increasing the contact area, but their twisted structure also generates longitudinal shear force and overturning effect on the rubber material, which fully disperses and mixes the raw materials inside the rubber material, ensuring that flame retardants and other components are evenly dispersed.

[0029] It is worth noting that this device is equipped with a motor synchronizer, which establishes an electrical connection with two rotating motors 3. By collecting the speed and direction signals of the two motors in real time and performing closed-loop regulation, the operating parameters (speed and phase) of the two rotating motors 3 are completely synchronized; thereby, the operating trajectory of the two stirring rods 32 can be constrained, thus avoiding motion interference between them.

[0030] In the example of this application, the two ends of the sliding sleeve 13 are fixedly connected to the two sides of the support plate 12, and the top side profile of the sliding sleeve 13 is triangular.

[0031] As a preferred example of this utility model, when the support plate 12 bears the weight of the stirring assembly and the reaction force generated by stirring, the force will be evenly transmitted to the sliding sleeve 13 through the fixed connection point, avoiding deformation caused by the support plate 12 being subjected to force on one side. The triangular structure of the top side profile of the sliding sleeve 13 utilizes the stability characteristics of triangles, enhancing the deformation resistance of the sliding sleeve 13 itself, and enabling it to stably bear the weight of the upper assembly.

[0032] In the example of this application, the size of the lead screw 21 is adapted to the size of the lead screw sleeve 22, and the lead screw 21 and the lead screw sleeve 22 are threaded together.

[0033] As a preferred example of this utility model, when the self-locking motor 2 drives the lead screw 21 to rotate, the meshing force between the threads converts the rotational motion into the linear motion of the lead screw sleeve 22. Since the lead screw sleeve 22 is fixedly connected to the support plate 12, it drives the support plate 12 to rise and fall.

[0034] In the example of this application, the lower end of the support frame 33 is detachably connected to the support plate 12 by bolts, and the upper end of the electric cylinder 34 is detachably connected to the upper end of the support frame 33.

[0035] As a preferred example of this utility model, when the device needs maintenance, the support frame 33 can be separated from the support plate 12 by unscrewing the bolts, which facilitates the inspection and maintenance of each component. During operation, the support frame 33 provides stable mounting support for the electric cylinder 34. The electric cylinder 34 drives the rotary motor 3 to move through the telescopic action. Different specifications of electric cylinders 34 can provide different thrust and telescopic stroke to adapt to different stirring and adjustment needs.

[0036] In the example of this application, the base 1 has a ramp 4 on the side away from the fixing frame 11, and the ramp 4 is located below the support plate 12.

[0037] As a preferred example of this utility model, when placing the material bucket, the operator can push the bucket to the lower end of the ramp 4. With the help of the inclination angle of the ramp 4, the bucket can be pushed upward along the ramp 4 to the designated position with a small pushing force. After the rubber compound is prepared, the bucket can slide down the ramp 4 naturally, reducing the difficulty of handling.

[0038] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
