Abstract
Description
Technical Field
[0001] This invention relates to the field of feeding device technology, and specifically to a powder feeding port structure. Background Technology
[0002] Terephthalic acid (PTA) powder is a core raw material in the chemical fiber industry, especially in the production of polyester fibers (such as polyester). Its application is mainly reflected in the synthesis of polyester as a basic chemical raw material, and further processing into various chemical fibers. In daily work, we need to put it into the feeding port and send it into the conveying pipe, and then the conveying pipe will transport it to the equipment that needs to be processed. However, the existing powder is generally packaged in a bag, which has a certain weight. It is quite laborious to put it into the feeding port by hand. Summary of the Invention
[0003] The present invention provides a powder feeding port structure to solve the above-mentioned technical problems, which allows powder to be fed into the feeding port more effortlessly.
[0004] To solve the above-mentioned technical problems, the technical solution of the present invention for a powder feeding port structure is as follows:
[0005] The device includes a discharge pipe and a hopper connected above the discharge pipe; an outer baffle is connected to the outer side of the hopper, and an inlet is provided on one side of the outer baffle; a tilting baffle is rotatably connected to the lower end of the inlet of the hopper; a telescopic push rod for controlling the tilting baffle to tilt is connected below the hopper; when the tilting baffle is closed, the tilting baffle closes the inlet; a first longitudinal support rod and a second longitudinal support rod are connected inside the outer baffle; the second longitudinal support rod is closer to the inlet than the first longitudinal support rod; a rotating connecting frame is provided in the middle of the second longitudinal support rod; a rotating shaft is connected to the rotating connecting frame; a levering frame is rotatably connected to the rotating shaft; the inner end of the levering frame is rotatably connected to the rotating shaft, and a limit bracket is connected to the outer end; when the tilting baffle is closed, the levering frame rests against the top of the tilting baffle, and the levering frame tilts upward from the inner end to the outer end; when the tilting baffle is open, the levering frame rests against the top of the hopper, and the inner end of the levering frame tilts downward from the outer end.
[0006] The outer baffle is also connected to a limiting frame; the limiting frame includes an upper longitudinal baffle and two side baffles; the upper longitudinal baffle is connected to the outer baffle and is located above the first longitudinal support rod away from the inlet side; both side baffles are connected between the upper longitudinal baffle and the second longitudinal support rod, and the two side baffles are located on both sides of the rotating connecting frame.
[0007] The upper longitudinal stop bar and the first longitudinal support bar are longitudinally slidably connected by a longitudinal slide; a cutting machine is installed on the longitudinal slide.
[0008] Both the upper longitudinal stop and the first longitudinal support are connected to longitudinal guide rods; the longitudinal carriage is longitudinally slidably connected to the two longitudinal guide rods.
[0009] The outer frame is also connected to a control mechanism for controlling the longitudinal movement of the longitudinal carriage; the control mechanism includes a motor and a longitudinal screw rotatably connected to the outer frame; the longitudinal screw is threadedly connected to the longitudinal carriage; the motor is mounted on the outer frame, and a first pulley is connected to the motor shaft; therefore, a second pulley is connected to the longitudinal screw; the first pulley and the second pulley are connected by a transmission belt.
[0010] The lower end of the discharge pipe is connected to a flange.
[0011] The hopper is equipped with four support legs at its four corners; of the four support legs, the two legs located below the inlet are connected to mounting panels; one end of the telescopic push rod is hinged to the mounting panel, and the other end is hinged to the tilting baffle.
[0012] The technical effects that this invention can achieve are:
[0013] 1. When feeding powder, the present invention first opens the flip-over baffle, so that the lever frame is placed above the hopper. At this time, the packaging bag containing powder is placed on the limiting bracket end of the lever frame. Because the height of this position is low, it is relatively easy to put the packaging bag. Then, the telescopic push rod is opened, and the flip-over baffle is closed by pushing the telescopic push rod. At the same time as the flip-over baffle closes, it pushes the lever frame to rotate upward until the lever frame tilts upward from the inner end to the outer end. At this time, the packaging bag slides down the lever frame into the outer baffle frame to complete the feeding. This feeding method is relatively labor-saving.
[0014] 2. The present invention is equipped with a limiting frame. When the packaging bag slides down the lever frame into the outer baffle to complete the feeding, the limiting frame can limit the packaging bag to be positioned directly above the hopper, that is, between the lever frame and the limiting frame.
[0015] 3. When feeding is completed, the present invention can cut the packaging bag with a cutting machine, so that the powder inside the packaging bag falls into the hopper and is discharged through the discharge pipe; and during the discharge process, the operator can shake the lever frame up and down to make the powder inside the packaging bag fall out more thoroughly, thereby reducing the powder residue inside the packaging bag.

[0023] The invention will now be described in further detail with reference to the accompanying drawings.
[0024] See Figures 1 to 6 .
[0025] A powder feeding port structure includes a discharge pipe 1 and a hopper 2 connected above the discharge pipe 1. An outer baffle 3 is connected to the outer side of the hopper 2. An inlet 61 is provided on one side of the outer baffle 3. A flip baffle 4 is rotatably connected to the lower end of the inlet 61 of the hopper 2. A telescopic push rod 5 for controlling the flip baffle 4 to flip is connected below the hopper 2. Specifically, the telescopic push rod 5 can be an electric telescopic push rod. When the flip baffle 4 is closed, the flip baffle 4 closes the inlet 61. A first longitudinal support rod 6 and a second longitudinal support rod 13 are connected inside the outer baffle 3. The second longitudinal support rod 13 is closer to the inlet 61 than the first longitudinal support rod 6. A rotating connecting frame 7 is provided in the middle of the second longitudinal support rod 13. A rotating shaft 8 is connected to the rotating connecting frame 7. A lever 9 is rotatably connected to the rotating shaft 8. The inner end of the lever 9 is rotatably connected to the rotating shaft 8, and the outer end is connected to a limit bracket 10.
[0026] Specifically, the present invention also connects a limiting frame inside the outer baffle 3. The limiting frame includes an upper longitudinal baffle 11 and two side baffles 12. The upper longitudinal baffle 11 is connected to the outer baffle 3 and is located above the first longitudinal support rod 6 on the side away from the inlet 61. The two side baffles 12 are connected between the upper longitudinal baffle 11 and the second longitudinal support rod 13, and the two side baffles 12 are located on both sides of the rotating connecting frame 7.
[0027] In the connection of the telescopic push rod 5, the four corners of the hopper 2 of the present invention are all connected to the support legs 52; among the four support legs 52, the two support legs 52 located below the inlet 61 are connected to the mounting panel 53; one end of the telescopic push rod 5 is hinged to the mounting panel 53, and the other end is hinged to the flip baffle 4.
[0028] When using this invention, first open the flip-up baffle 4 (see reference). Figure 5 At this point, the lever 9 is positioned above the hopper 2, with its inner end tilted downwards towards the outer end. The limiting bracket 10 is positioned relatively low. The packaging bag containing the powder is placed on the limiting bracket 10. Then, the telescopic push rod 5 is opened, pushing the tilting baffle 4 upwards. Figure 1 Position, lever frame 9 also rotates upwards by the push of flip baffle 4 until it rotates to Figure 1 At this point, the support frame 9 tilts upwards from the inner end to the outer end, while the packaging bag located on the limiting bracket 10 slides down into the outer baffle 3 due to gravity and rests against the limiting frame (see reference). Figure 3 The packaging bag containing the powder is located directly above hopper 2.
[0029] Preferably, the present invention has a longitudinal slide 21 longitudinally slidably connected to the upper longitudinal stop bar 11 and the first longitudinal support bar 6, and a cutting machine 22 is mounted on the longitudinal slide 21; specifically, longitudinal guide rods 31 are connected below the upper longitudinal stop bar 11 and below the first longitudinal support bar 6, and the longitudinal slide 21 is longitudinally slidably connected to the two longitudinal guide rods 31; a control mechanism for controlling the longitudinal movement of the longitudinal slide 21 is also connected to the outer baffle frame 3; the control mechanism includes a motor 41 and a longitudinal screw 42 rotatably connected to the outer baffle frame 3, and the longitudinal screw 42 is threadedly connected to the longitudinal slide 21; the motor 41 is mounted on the outer baffle frame 3, and a first pulley 43 is connected to the shaft of the motor 41, and a second pulley 44 is connected to the longitudinal screw 42, and the first pulley 43 and the second pulley 44 are connected by a transmission belt 45; preferably, a flange 51 is connected to the lower end of the discharge pipe 1 to facilitate the connection between the discharge pipe 1 and the conveying pipe.
[0030] In this invention, after the packaging bag containing powder is placed into the outer baffle 3, the cutting machine 22 and the motor 41 are turned on. The motor 41 controls the longitudinal slide 21 and the cutting machine 22 to move longitudinally to cut the packaging bag, thereby causing the powder inside the packaging bag to fall out. During the process of the powder falling out, the staff can shake the lever 9 to shake the packaging bag, thereby accelerating the speed at which the powder falls out of the packaging bag and reducing the amount of powder residue inside the packaging bag.
[0031] In terms of control mechanism, the present invention controls the forward and reverse rotation of the first pulley 43 by the motor 41, thereby controlling the forward and reverse rotation of the second pulley 44 and the longitudinal screw 42. Since the longitudinal screw 42 is threadedly connected to the longitudinal slide 21, and the longitudinal slide 21 is longitudinally slidably connected to the two longitudinal guide rods 31, the longitudinal movement of the longitudinal slide 21 and the cutting machine 22 can be controlled at the same time as the longitudinal screw 42 rotates forward and reverse.
