[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent mating surfaces and prevent external impurities such as dust and moisture from invading components inside machinery and equipment. Although rubber and plastic seals are small, their functions make them basic components and accessories in major national economic industries such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing, and they occupy a very important position in the development of the national economy. Due to the wide application of sealing rings, during the injection molding production of pipe seals, the raw material particles need to be lifted to the injection molding equipment for hot melting before injection molding. In actual production, the size of the raw material particles directly affects the working conditions of the injection molding equipment for pipe seals. However, the existing feeding device based on the injection molding production of pipe seals is not convenient for screening the raw material particles, and cannot accurately affect the working conditions of the injection molding equipment for pipe seals, which can easily affect the quality of pipe seals.

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] Example:

[0023] See also Figure 1-4 A feeding device based on the injection molding production of pipe fittings and seals includes a base frame 1 and a conveyor belt 2 arranged above the base frame 1. A plurality of lifting and lowering adjustable baffle structures are evenly distributed on the conveyor belt 2 in the circumferential direction. The baffle structures include arc-shaped baffle bars 3. Both ends of the arc-shaped baffle bars 3 are connected to the conveyor belt 2 through a lifting and lowering adjustment mechanism. A height adjustment structure that can raise one end of the conveyor belt 2 is also provided between the base frame 1 and the conveyor belt 2. Furthermore, the arc-shaped baffle bar 3 is configured as a soft strip structure. When the weight of the raw material particles blocked by the arc-shaped baffle bar 3 increases, the arc-shaped baffle bar 3 is deformed, and the feeding amount of the raw material particles can be understood through the deformation.

[0024] Specifically, the lifting and adjusting mechanism includes a fixed sleeve 4 fixedly installed on the end of the arc-shaped baffle 3, and a lifting and adjusting member with a screw segment 7 at the bottom is rotatably connected to the fixed sleeve 4. Both sides of the conveyor belt 2 are circumferentially evenly provided with a plurality of threaded through holes threadedly connected to the screw segment 7. Through the cooperation of the fixed sleeve 4, the screw segment 7 and the threaded through holes on the conveyor belt 2, by rotating the lifting and adjusting member, the height of the screw segment 7 passing through the threaded through hole can be adjusted, thereby adjusting the height of the arc-shaped baffle 3 from the conveyor belt 2.

[0025] Specifically, the lifting and lowering adjusting member includes an adjusting cap 6 , and the adjusting cap 6 is fixedly connected to the screw segment 7 with a rotating shaft segment 5 rotatably connected to the fixing sleeve 4 . The screw segment 7 can be driven to rotate through the rotating shaft segment 5 through the adjusting cap 6 .

[0026] Specifically, the height adjustment structure includes a driving cylinder 9 and a loading rack 8. Both ends of the loading rack 8 are rotatably connected to transmission rollers 10, and the conveyor belt 2 is mounted on the two transmission rollers 10. One end of the loading rack 8 is rotatably connected to the base frame 1, and the other end of the loading rack 8 is hinged to the base frame 1 through the driving cylinder 9. By extending and retracting the driving cylinder 9, it is convenient to simultaneously lift and lower the loading rack 8 and one end of the conveyor belt 2, thereby adjusting the loading height of the conveyor belt 2.

[0027] Specifically, the loading rack 8 is also provided with a driving mechanism for driving one of the transmission rollers 10 to rotate, and the driving mechanism includes a driving motor 11 fixedly installed at the bottom of the loading rack 8 through a U-shaped frame, and the output shaft of the driving motor 11 is connected to one of the transmission rollers 10 through a sprocket chain 12. When the driving motor 11 is started, one of the transmission rollers 10 can be driven to rotate through the transmission connection of the sprocket chain 12, thereby driving the conveyor belt 2 to rotate, thereby facilitating the loading operation.

[0028] Specifically, a positioning shaft 14 and a lifting shaft 13 are fixedly installed on both sides of the loading rack 8, the positioning shaft 14 is rotatably connected to the base frame 1, the top output end of the driving cylinder 9 is rotatably connected to the lifting shaft 13, and the bottom of the driving cylinder 9 is rotatably connected to the base frame 1. Through the arrangement of the lifting shaft 13 and the positioning shaft 14, the stability of the conveyor belt 2 during height adjustment is conveniently improved.

[0029] Specifically, a plurality of universal wheels 15 with a locking function are fixedly mounted on the bottom of the base frame 1 , and the plurality of universal wheels 15 facilitate the position movement and position locking of the device.

[0030] When in use, according to the height of the material to be loaded, one end of the conveyor belt 2 is raised to the corresponding height through the height adjustment structure. First, the multiple arc-shaped baffles 3 can be adjusted from the bottom in turn to a certain height with the conveyor belt 2, so that the raw material particles can be poured onto the conveyor belt 2, and the raw material particles can be lifted upward by the multiple arc-shaped baffles 3. The raw material particles that are smaller than the distance between the arc-shaped baffles 3 and the conveyor belt 2 will slide down with the conveyor belt 2, so that the smaller particles can be screened out, and then the distance between several adjacent arc-shaped baffles 3 and the conveyor belt 2 can be raised in turn along the loading direction, so that the raw material particles can be screened in turn, and particles of different specifications can be observed intuitively. Then, the working conditions of the pipe fittings and seals injection molding equipment can be conveniently and accurately adjusted, so as to ensure the production quality of the pipe fittings and seals.
