A quantitative batch dosing system

Abstract

This invention discloses a quantitative batch injection system, including a workbench with an output pipe connected to the top of the output pipe and an input pipe fixedly connected below the workbench; a first gear connected to the output pipe and meshing with a toothed plate; a switching component that drives the input pipe to reciprocate for quantitative batch injection via the first gear; a control component that controls the injection hopper via the movable toothed plate; and a docking component that cooperates with the switching component to allow the output pipe to fit into the input pipe. Under the action of the first gear, the output pipe of this invention performs a reciprocating circular motion. Injection occurs when the output pipe is above the input pipe, and injection stops when the output pipe moves away from the input pipe. The movement of the output pipe causes residue to fall, promptly cleaning the residue remaining on the inner wall of the output pipe and avoiding its influence on the injection volume of the next injection.

Description

Technical Field

[0001] This invention relates to the field of papermaking infusion device technology, specifically a quantitative batch infusion system. Background Technology

[0002] The production process of wet wipes, toilet paper, etc. generally involves waste paper entering a hydrapulper, which beats and deinks the waste paper. After beating and deinking, the pulp is separated by a high-frequency vibrating screen and then injected into the wire groove in batches through a feeding device to initially form rolls of paper.

[0003] Existing batch injection systems are generally controlled by sensors, directly connecting the output and input pipes. The output pipe is transported by controlling the sensor gap, thereby achieving quantitative batch injection. However, in this method, when the injection stops during the gap, the residue remaining in the output pipe cannot be cleaned in time, and the amount of residue affects the quantitative injection of the next time.

[0004] To address this, we propose a quantitative batch injection system. Summary of the Invention

[0007] Preferably, the switching assembly includes a first rotating shaft rotatably connected to the worktable, a first rotating plate movably sleeved on the first rotating shaft, a second rotating shaft fixedly connected to the end of the first rotating plate, a connecting plate rotatably connected to the bottom of the second rotating shaft, and a connecting pipe fixedly connected to the output pipe on the connecting plate, the connecting pipe passing through the first gear.

[0008] Preferably, the switching component further includes an internal gear ring, a second gear is provided in the middle of the internal gear ring, the first gear meshes with the second gear and the internal gear ring simultaneously, a ring plate that cooperates with the first gear is fixedly connected to the top and bottom of the internal gear ring, a limiting ring that cooperates with the rotation of the worktable is fixedly connected to the outer ring of the internal gear ring, and a power component that drives the first rotating plate and the first gear to reciprocate is provided below the second gear.

[0009] Preferably, the power assembly includes a motor embedded in the worktable, the output shaft of the motor is connected and fixed to the central shaft of the second gear, the second gear has a circular groove, the second gear also has a straight groove communicating with the circular groove, and a sliding column that slides in cooperation with the circular groove is fixedly connected to the first rotating plate.

[0010] Preferably, the control component includes a first telescopic plate that is fixedly connected to the worktable and has a first compression member inside. The end of the first telescopic plate is fixedly connected to the toothed plate. A contact plate is fixedly connected to the first telescopic plate, and the end of the toothed plate and the contact plate cooperate with each other through contact.

[0011] Preferably, the docking assembly includes a contact cylinder in the shape of an inverted frustum, a plurality of connecting rods are fixedly connected between the contact cylinder and the connecting pipe, a movable groove is provided on the toothed plate, a second telescopic plate that is slidably fitted in the movable groove and fixedly connected to the worktable, an arc-shaped plate that abuts against the contact cylinder is fixedly connected to the top of the second telescopic plate, a second compression member is provided in the second telescopic plate, an L-shaped groove that communicates with the movable groove is provided in the toothed plate, and a limiting post that is slidably fitted in the L-shaped groove and fixedly connected to the second telescopic plate.

[0012] Preferably, the docking assembly further includes a second rotating plate that is fixedly connected to the first rotating shaft. The second rotating plate is in movable cooperation with both the second rotating shaft and the sliding column. A plurality of first compression springs are connected between the first rotating shaft and the second rotating shaft. A contact column that abuts against the first rotating plate is fixedly connected to the second gear.

[0013] Preferably, the ring plate is movably fitted with a pressing post that presses against the connecting plate, and a plurality of second compression springs are connected between the pressing post and the ring plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Under the action of the first gear, the output tube of the present invention makes a reciprocating circular motion. When the output tube is above the input tube, injection is performed. When the output tube is away from the input tube, injection stops. The movement of the output tube causes the residue to fall down, and the residue remaining on the inner wall of the output tube is cleaned in time to avoid affecting the injection volume of the next injection.

[0016] 2. The circular groove and sliding column ensure that the first gear and the output pipe stay above the input pipe for a certain period of time, thus ensuring quantitative injection. Before injection, the connecting pipe is automatically connected to the input pipe. When injection is not needed, the connection is automatically disengaged. This method ensures the injection volume and sealing, and avoids injection volume loss.

[0017] 3. When the output pipe and the first gear move directly above the input pipe, the second telescopic plate presses against the contact cylinder. With the help of the limiting post and the L-shaped groove, the position of the gear plate is corrected, ensuring smooth and stable meshing between the first gear and the gear plate. This helps the gear plate move accurately to the contact plate, ensuring precise control and guaranteeing the gap time.

[0018] 4. By cooperating with the rotating internal gear ring, the pressure column acts on the connecting plate, causing the output pipe to vibrate, which helps the residue fall off and facilitates rapid material injection when the input and output pipes are connected, avoiding blockage.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figures 1-3 The illustrated quantitative batch injection system includes a workbench 1 with an output pipe 2 connected to the top of the output pipe 2, and an input pipe 3 fixedly connected to the bottom of the workbench 1. It also includes a first gear 4 connected to the output pipe 2, which meshes with a toothed plate 5; a switching component 6, which drives the input pipe 3 to reciprocate for quantitative batch injection via the first gear 4; a control component 21, which controls the injection hopper via the movable toothed plate 5; and a docking component 24, which cooperates with the switching component 6 to insert the output pipe 2 into the input pipe 3.

[0035] Please see Figures 4-6The switching component 6 shown in the figure includes a first rotating shaft 7 rotatably connected to the worktable 1. A first rotating plate 8 is movably sleeved on the first rotating shaft 7. A second rotating shaft 9 is fixedly connected to the end of the first rotating plate 8. A connecting plate 10 is rotatably connected to the bottom of the second rotating shaft 9. A connecting pipe 11, which is fixedly connected to the output pipe 2, is fixedly connected to the connecting plate 10. The connecting pipe 11 passes through the first gear 4.

[0036] Please see Figures 6-7 The switching component 6 shown in the figure also includes an internal gear ring 12. A second gear 13 is provided in the middle of the internal gear ring 12. The first gear 4 meshes with both the second gear 13 and the internal gear ring 12. A ring plate 14 that cooperates with the first gear 4 is fixedly connected to the top and bottom of the internal gear ring 12. A limiting ring 15 that cooperates with the rotation of the worktable 1 is fixedly connected to the outer ring of the internal gear ring 12. A power component 16 that drives the first rotating plate 8 and the first gear 4 to reciprocate is provided below the second gear 13.

[0037] Please see Figures 6-7 The power assembly 16 shown in the figure includes a motor 17 embedded in the worktable 1. The output shaft of the motor 17 is connected and fixed to the central shaft of the second gear 13. A circular groove 18 is provided on the second gear 13. A straight groove 19 communicating with the circular groove 18 is also provided on the second gear 13. A sliding column 20 that slides in cooperation with the circular groove 18 is fixedly connected to the first rotating plate 8.

[0038] Please see Figures 7-9 The control component 21 shown in the figure includes a first telescopic plate 22 that is fixedly connected to the workbench 1 and has a first compression member inside. The end of the first telescopic plate 22 is fixedly connected to the toothed plate 5. A contact plate 23 is fixedly connected to the first telescopic plate 22. The end of the toothed plate 5 and the contact plate 23 cooperate with each other through contact.

[0039] Please see Figures 9-12 The docking assembly 24 shown in the figure includes a contact cylinder 25 in the shape of an inverted frustum. Multiple connecting rods 26 are fixedly connected between the contact cylinder 25 and the connecting pipe 11. A movable groove 27 is provided on the toothed plate 5. A second telescopic plate 28, which is connected and fixed to the worktable 1, is slidably fitted in the movable groove 27. An arc-shaped plate 29, which abuts against the contact cylinder 25, is fixedly connected to the top of the second telescopic plate 28. A second compression member is provided in the second telescopic plate 28. An L-shaped groove 30, which communicates with the movable groove 27, is provided in the toothed plate 5. A limiting post 31, which is connected and fixed to the second telescopic plate 28, is slidably fitted in the L-shaped groove 30.

[0040] In this embodiment, when the toothed plate 5 contacts the contact plate 23, the first gear 4 moves above the input pipe 3 and inserts the connecting cylinder into the input pipe 3. At the same time, the slurry in the injection chamber passes through the output pipe 2, the connecting cylinder, and enters the input pipe 3, thereby completing the quantitative batch injection. When the toothed plate 5 contacts the contact plate 23, the signal is connected, which starts the extrusion device (conventional technology) in the injection chamber and begins the injection.

[0041] When the motor 17 rotates, it drives the second gear 13 to rotate counterclockwise. The sliding column 20 enters the circular groove 18 from the straight groove 19, so that the first gear 4 contacts the tooth plate 5 (and at this time the first gear 4, the output pipe 2, and the connecting pipe 11 are located directly above the input pipe 3). Then the first gear 4 rotates in its original position, and the internal gear ring 12 rotates.

[0042] When the sliding column 20 enters the circular groove 18 from the straight groove 19, the connecting cylinder moves downwards while moving towards the toothed plate 5. The connecting cylinder contacts the arc plate 29. The cooperation between the arc plate 29 and the connecting cylinder corrects the position of the toothed plate 5, causing the second telescopic plate 28 to retract. The limiting column 31 moves on the L-shaped groove 30. When the sliding column 20 moves in the circular groove 18, the first gear 4 makes smooth contact with the toothed plate 5. The rotating first gear 4 drives the toothed plate 5 to move and contact the contact plate 23, so that the slurry in the injection chamber is injected.

[0043] The second gear 13 continues to rotate. When the sliding column 20 enters the straight groove 19 from the circular groove 18, the first rotating plate 8 moves upward and rotates around the first rotating shaft 7, thereby driving the first gear 4 to make a circular motion away from the tooth plate 5 (and rotate on its own), so that the connecting cylinder and the output pipe 2 move away from the input pipe 3. When the sliding column 20 passes through the middle of the straight groove 19, the first gear 4 drives the connecting cylinder and the output pipe 2 to make a circular motion close to the tooth plate 5, wherein the position of the straight groove 19 passes through the central axis of the second gear 13.

[0044] Example 2

[0045] Please see Figures 5-6 The docking assembly 24 shown in the figure also includes a second rotating plate 32 that is fixedly connected to the first rotating shaft 7. The second rotating plate 32 is in movable cooperation with the second rotating shaft 9 and the sliding column 20. Multiple first compression springs 33 are connected between the first rotating shaft 7 and the second rotating shaft 9. A contact column 34 that abuts against the first rotating plate 8 is fixedly connected to the second gear 13.

[0046] In this embodiment, when the sliding column 20 enters the circular groove 18 from the straight groove 19, the first rotating plate 8 disengages from the contact column 34. Under the action of the second rotating plate 32 and the compression spring, and with the limiting action of the first rotating shaft 7, the second rotating shaft 9, and the sliding column 20, the second pressure plate drives the connecting plate 10 to move downward, thereby causing the input pipe 3 and the connecting cylinder to move downward along the middle of the first gear 4, and driving the connecting cylinder to be inserted into the input pipe 3.

[0047] The second gear 13 continues to rotate. When the sliding column 20 enters the straight groove 19 from the circular groove 18, the first rotating plate 8 contacts the contact column 34, causing the first rotating plate 8 to move upward, thereby causing the connecting cylinder to move upward and disengage from the input pipe 3, and then driving the first gear 4 to make a circular motion.

[0048] When the first rotating plate 8 disengages from the contact post 34, the second rotating plate 32 will not move downward under the action of the first rotating shaft 7. The first compression spring 33 causes the first rotating plate 8 to move downward along the first rotating shaft 7, and the sliding post 20 and the second rotating shaft 9 cause the first rotating plate 8 to move downward.

[0049] Example 3

[0050] Please see Figures 3-4 The ring plate 14 shown in the figure has a pressing post 35 that is movably fitted to the connecting plate 10. Multiple second compression springs 36 are connected between the pressing post 35 and the ring plate 14.

[0051] In this embodiment, while the internal toothed ring 12 rotates, it acts on the connecting plate 10, thereby causing the connecting pipe 11 and the output pipe 2 to vibrate slightly, which facilitates rapid material injection and timely removal of residues in the output pipe 2. The removed residues enter the collection device for further processing (the collection device is a conventional technical means in the field, and will not be described in detail in this solution).
