Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a quantitative feeding device for preparing a curing agent. Background Art

[0002] Curing agents are substances or mixtures that enhance or control the curing reaction. Resin curing is a process that irreversibly changes thermosetting resins through chemical reactions such as condensation, ring closure, addition, or catalysis. Curing is accomplished by adding a curing (crosslinking) agent. Curing agents are essential additives, and are required for all epoxy resins used in adhesives, coatings, and castables. Without them, epoxy resins will not cure.

[0003] The quantitative addition of materials during the preparation of the curing agent can effectively guarantee its performance. For the addition of solid materials, the fixed volume barrel addition method is more common at this stage, but for large quantities, multiple additions are required, which is inefficient. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a quantitative feeding device for preparing a curing agent with a simple structure, convenient operation and high efficiency.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A quantitative feeding device for preparing a curing agent comprises a base, the base being provided with two hoppers, the upper ends of the hoppers being open and fixedly connected to the base via support columns, the lower ends of the hoppers being fixed with discharge pipes, the discharge pipes being fixedly connected to the base via bellows, the base being provided with a discharge port communicating with the bellows, and the base being further provided with a vibration structure for driving the bellows to vibrate;

[0007] The base is a rectangular frame with openings at both ends. Two quantitative cylinders are arranged in the base. A baffle is fixed to the upper end of the quantitative cylinder. The baffle is slidably fitted with the top wall of the frame. A clearance opening is provided through the baffle facing the barrel mouth of the quantitative cylinder; a discharge port is provided at the lower end of the base, and a movable structure for driving the two quantitative cylinders to move synchronously is also installed on the base.

[0008] In this way, the base is fixedly mounted on the equipment, with the discharge port facing the equipment's feed port. During quantitative feeding, the moving structure drives the two metering cylinders to move synchronously. When one metering cylinder is facing the discharge port, the other metering cylinder is facing the drop port. In other words, one metering cylinder is in the discharge state, and the other metering cylinder is in the drop state. As the raw materials in the hopper fall through the bellows into the metering cylinders, the vibrating structure drives the bellows to vibrate, preventing material accumulation and allowing the raw materials to enter the metering cylinders more easily, thereby improving feeding accuracy.

[0009] In which, the vibration structure includes a mounting plate, two vertically arranged columns are fixedly mounted on the base, the mounting plate is fixedly mounted on the columns, two reduction motors are fixedly mounted on the mounting plate, the output shaft of the reduction motor passes through the mounting plate and is fixedly connected to a first connecting rod, the end of the first connecting rod away from the output shaft of the motor is rotatably connected to the second connecting rod, the end of the second connecting rod not connected to the first connecting rod is rotatably connected to the third connecting rod, a pipe sleeve is fixed to the outside of the bellows, the pipe sleeve is fixedly connected to the end of the third connecting rod not connected to the second connecting rod, a sliding sleeve is fixed on the mounting plate through a support rod, and the third connecting rod slides in cooperation with the sliding rod.

[0010] Among them, the movable structure includes two hydraulic cylinders fixedly installed on the outside of the base, and the two metering cylinders are fixedly connected by a fixed block. Sliders are fixed on both sides of the fixed block. Slide grooves that slide with the slides are opened on both sides of the base. The slides are fixedly connected to the cylinder rod of the hydraulic cylinder through the slide grooves.

[0011] Wherein, a convex edge is fixed on the lower end of the metering cylinder and is slidably matched with the bottom wall of the base.

[0012] The diameter of the lower end of the hopper gradually decreases in the direction approaching the discharge pipe.

[0013] In summary, the quantitative feeding device for preparing a curing agent has the advantages of simple structure, convenient operation and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0018] like Figure 1-3 As shown, a quantitative feeding device for preparing a curing agent includes a base 1, on which two hoppers 2 are provided. The upper ends of the hoppers are open and fixedly connected to the base via support columns 3. A discharge pipe 4 is fixed to the lower end of the hopper, and the discharge pipe is fixedly connected to the base via a bellows 5. The base is provided with a discharge port connected to the bellows, and a vibration structure for driving the bellows to vibrate is also installed on the base;

[0019] The base is a rectangular frame with openings at both ends. Two quantitative cylinders 6 are arranged in the base. A baffle 7 is fixed to the upper end of the quantitative cylinder. The baffle is slidably fitted with the top wall of the frame. A clearance opening is provided through the baffle facing the barrel mouth of the quantitative cylinder; a discharge port is provided at the lower end of the base, and a moving structure for driving the two quantitative cylinders to move synchronously is also installed on the base.

[0020] In this way, the base is fixedly mounted on the equipment, with the discharge port facing the equipment's feed port. During quantitative feeding, the moving structure drives the two metering cylinders to move synchronously. When one metering cylinder is facing the discharge port, the baffle connected to it blocks the discharge port, and the other metering cylinder faces the discharge port. That is, one metering cylinder is in the discharge state, and the other metering cylinder is in the discharge state. When the raw materials in the hopper fall through the bellows into the metering cylinder, the vibrating structure drives the bellows to vibrate, preventing the accumulation of raw materials, allowing the raw materials to enter the metering cylinder more easily, and improving the accuracy of feeding.

[0021] During implementation, the vibration structure includes a mounting plate 8, two vertically arranged columns are fixedly mounted on the base, the mounting plate is fixedly mounted on the columns, two reduction motors 9 are fixedly mounted on the mounting plate, the output shaft of the reduction motor passes through the mounting plate and is fixedly connected to a first connecting rod 11, the end of the first connecting rod away from the output shaft of the motor is rotatably connected to the second connecting rod 12, the end of the second connecting rod not connected to the first connecting rod is rotatably connected to the third connecting rod 13, a pipe sleeve 14 is fixed to the outside of the bellows, the pipe sleeve is fixedly connected to the end of the third connecting rod not connected to the second connecting rod, a sliding sleeve 15 is fixed on the mounting plate through a support rod, and the third connecting rod slides in cooperation with the sliding rod.

[0022] In this way, the reduction motor drives the first connecting rod to rotate, and drives the bellows to move back and forth through the transmission of the second connecting rod and the third connecting rod, thereby realizing the vibration of the bellows and improving the smoothness of blanking.

[0023] In practice, the mobile structure includes two hydraulic cylinders 16 fixedly mounted on the outside of the base. The two metering cylinders are fixedly connected by a fixed block 17. Sliders 18 are fixed to either side of the fixed block. Sliders 18 slide through the grooves on both sides of the base, which slide in conjunction with the sliders. The sliders are fixedly connected to the cylinder rods of the hydraulic cylinders through the grooves. The hydraulic cylinders drive the sliders to move, which in turn drives the fixed block to move, achieving synchronous movement of the two metering cylinders.

[0024] During implementation, a convex edge 19 is fixed to the lower end of the metering cylinder and is in sliding engagement with the bottom wall of the base, thereby improving the stability of the movement process.

[0025] During implementation, the diameter of the lower end of the hopper gradually decreases in the direction close to the discharge pipe, so as to facilitate the movement of the raw materials toward the discharge pipe.

[0026] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
