Description

An underground transmission device for paper product processing scraps

Technical Field

The invention belongs to the technical field of transmission devices, in particular to an underground transmission device for paper product processing scraps.

Background technique

When paper products are processed, a large amount of scraps will be generated. In order to prevent the scraps from affecting the operation of the processing machinery, a transmission device is needed to transport and transfer them. Since paper product particles are light in texture, they are easily affected by external wind and scattered everywhere, and the processing machinery occupies a large space. Therefore, most factories currently use underground transmission devices for transportation, and then special workers collect and transport the scraps. The collected scraps can be reused. Since paper scraps of different particle sizes have different uses, paper scraps with larger particle sizes can be used to make pulp, and paper scraps with smaller particle sizes can be used to fill some items, such as toys, cushions, etc., so the scraps need to be screened after being discharged from the processing machinery.

A patent with publication number CN209009687U discloses a scrap material transmission device for paper product processing, which belongs to the field of transmission devices and includes a support frame, a driven wheel is installed on the rotating shaft, a conveyor belt is connected to the rotating shaft, the driving wheel and the driven wheel and the driven wheels are connected by belts, a first fan is installed on the left inner wall and the right inner wall of the processing box, and a second fan is installed on the right inner wall of the crushing box; the utility model has the advantages of small difference in scrap size and easy transmission.

However, the above technical solution still has the following deficiencies in practical application:

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

The self-cleaning dredging mechanism includes a second sliding rod 39 fixedly connected to the rear end of the frame 7, the second sliding rod 39 is slidably connected to the shell 25, and a plurality of brush rods 26 are slidably connected to the upper end of the shell 25. A mounting frame 37 is fixedly connected to the front side of the upper end of the shell 25, and a shift plate shaft 35 is rotatably provided on the upper end of the mounting frame 37. The shift plate shaft 35 is sleeved and fixedly connected with a plurality of shift plates 34 for shifting the brush ends of the brush rods 26. A dust box 17 is fixedly connected to the middle part of the right end face of the shell 25, and a branch pipe 38 is connected to the middle part of the upper end of the dust box 17. The branch pipe 38 passes through and is fixedly connected to the right end of the shell 25, and the upper end of the branch pipe 38 is connected to the adsorption head 36.

Specifically, when paper products are processed, a large amount of scraps will be generated. In order to prevent the scraps from affecting the operation of the processing machinery, the scraps need to be cleaned out of the processing machinery and transported and transferred by underground transmission devices. Then, special workers collect and carry the scraps. The collected scraps can be reused. Since scraps of paper products with different particle sizes have different uses, scraps of paper products with larger particle sizes can be used to make pulp, and scraps of paper products with smaller particle sizes can be used to fill some items, such as toys, cushions, etc., so after the scraps are discharged from the processing machinery, the scraps need to be screened to separate the scraps of paper products with large particle sizes and small particle sizes, and use them separately. When the existing technology uses a screen to screen the scraps, the scraps may block the screen holes. When the scraps block the screen holes, the passing effect of the scraps will be affected;

When this embodiment is used, a placement groove is first opened on the ground on one side of the paper product processing equipment, and the device is placed in the placement groove. The scraps are discharged through the feed port 4 and fall to the upper end of the screen 5. Then, under the action of the electromagnetic vibrator 16, the screen 5 is vibrated, and the small-particle scraps will fall to the upper end of the conveyor belt 2 through the sieve hole 8. Then, under the clockwise rotation of the rotating roller 55, the conveyor belt 2 is operated to transport the small-particle scraps to the right. When the small-particle scraps move to the rightmost end of the conveyor belt 2, they will fall into the collection container, and the small-particle scraps can be collected.

When the screen 5 is working, the screen holes 8 may be blocked by small-particle scraps. In order to avoid this situation, when the screen 5 is working, the shell 25 can be driven to slide left and right on the second slide bar 39, so that the multiple groups of brush rods 26 move and align with the multiple groups of screen holes 8 in sequence, and the brush rods 26 coincide with the axis of the screen holes 8. Since the screen 5 moves vertically up and down when vibrating, there is no need to stop the screen 5 to align the brush rods 26 with the screen holes 8, and then drive the brush rods 26 to rise and rotate to insert them into the screen holes 8, and use the top end of the brush rod 26 to dredge the blocked scraps, and under the action of the rotation of the brush end, clean the scraps attached to the hole wall, so that the screen holes 8 can be dredged, and some small-particle scraps may fall downward with the movement of the brush rod 26. At this time, negative pressure can be used to remove the fallen scraps through the adsorption head 36 The suction head 36 is sucked into the dust collecting box 17 by the branch pipe 38. At the same time, since the brush rod 26 is rotating while being lifted, the suction head 36 can also uniformly absorb the scraps attached to the brush end of the brush rod 26, and drive the paddle shaft 35 to drive the multiple paddles 34 to rotate back and forth. The reciprocating rotation of the paddle plates 34 can pry the brush end of the brush rod 26, so that the scraps attached to the brush end can be shaken off. The shaken-off scraps can be sucked into the dust collecting box 17 through the suction head 36 for collection again, which can avoid the brush rod 26 attaching the attached scraps to the next group of sieve holes 8 again. Therefore, while using the brush rod 26 to dredge the sieve holes 8, it can also ensure the cleanliness of the brush rod 26 itself, and can also prevent small-grained scraps from falling on the self-cleaning dredging mechanism, affecting the normal use of the self-cleaning dredging mechanism, and the recycling effect is good.

When the screening work is completed, there is no small-particle scraps on the upper end of the screen 5. At this time, open the dust box 17, take out the small-particle scraps collected inside, pour them into the collection container, and mix them with the small-particle scraps transported to the collection container by the conveyor belt 2. The collection of small-particle scraps can be completed, and then the personnel transport and transfer them, and then place the empty collection container on the right end of the transmission cavity 1 again, ready to collect large-particle scraps. At this time, the scraps remaining on the upper end of the screen 5 are all large-particle scraps. The screen 5 can be driven to rotate clockwise to tilt the screen 5, so that the large-particle scraps slide to the upper end of the conveyor belt 2 under the action of gravity, and then move to the right with the conveyor belt 2 and fall into the collection container again. After loading is completed, it is transported and transferred again. At this point, the separation and collection of large-particle and small-particle scraps can be completed.

As shown in FIG. 1 , a chamber shell 3 is fixedly connected to the upper end of the transmission chamber 1 , and a feed port 4 is opened at one end of the chamber shell 3 .

Specifically, the scraps are discharged from the paper product processing equipment, discharged from the feed port 4 and then fall onto the upper end of the screen 5 .

As shown in FIG. 2 , a first motor 10 is fixedly connected to the front side of the left end face of the left frame 7 , a threaded rod 11 is fixedly connected to the output end of the first motor 10 , the threaded rod 11 is threadedly connected to the housing 25 , and both ends of the threaded rod 11 are rotatably disposed on the frame 7 .

Specifically, the first motor 10 drives the threaded rod 11 to rotate, so that the housing 25 can slide left and right on the second slide rod 39, so that the brush rod 26 can be displaced left and right, and the brush rod 26 is aligned with the sieve holes 8 to achieve the dredging work of multiple groups of sieve holes 8.

As shown in Figure 4, an L-shaped plate 27 is rotatably provided at the connection between the brush rod 26 and the shell 25 through a rotating shaft, and a second gear 28 and a first bevel gear 29 are rotatably provided at the lower end of the rear side of the L-shaped plate 27. A third gear 30 is fixedly connected to the connection between the brush rod 26 and the L-shaped plate 27 through a rotating shaft, and adjacent third gears 30 are meshed with each other. The rear third gear 30 is fixedly connected to a second bevel gear 31 through a rotating shaft, and the second bevel gear 31 is meshed with the first bevel gear 29. A hydraulic cylinder 32 is fixedly connected to the front side of the inner cavity of the shell 25, and the piston end of the hydraulic cylinder 32 is fixedly connected to the L-shaped plate 27. A second rack 33 is fixedly connected to the rear end of the right side of the inner cavity wall of the shell 25, and the second rack 33 is meshed with the second gear 28.

Specifically, when the brush rod 26 is aligned with the sieve hole 8 and coincides with the axis of the sieve hole 8, the hydraulic cylinder 32 can be started to drive the L-shaped plate 27 to rise, so that the brush rod 26 extends into the sieve hole 8. At the same time, with the cooperation of the second rack 33 and the second gear 28, the first bevel gear 29 is rotated, which can rotate the second bevel gear 31. Then, with the mutual engagement of multiple third gears 30, multiple brush rods 26 are rotated at the same time. When the brush rod 26 rises, its top end can be used to lift the scraps blocked by the sieve hole 8, so that the sieve hole 8 can be unblocked. When the brush rod 26 rotates, the scraps attached to the wall of the sieve hole 8 can be cleaned to avoid the scraps adhering to the wall of the hole.

As shown in Figures 4, 5 and 8, the front end of the paddle shaft 35 is sleeved and fixedly connected with the first gear 19, the upper right end of the front end surface of the shell 25 is fixedly connected with the fourth motor 22, the output end of the fourth motor 22 is fixedly connected with the crank 24 through a rotating shaft, and a rectangular block 23 is rotatably provided on the upper end of the crank 24. The rectangular block 23 is embedded with the first rack 20 and is slidably connected with the first rack 20. The upper end of the first rack 20 is slidably connected with the first slide bar 21, and both ends of the first slide bar 21 are fixedly connected to the mounting frame 37. The first rack 20 and the first gear 19 are meshed with each other, and an exhaust fan 18 is provided at the front end of the dust box 17.

Specifically, when the brush rod 26 completes a dredging work and descends, under the action of the fourth motor 22, the crank 24 drives the rectangular block 23 to make a circular motion, and the rectangular block 23 slides up and down in the groove of the first rack 20, so that the first rack 20 can slide left and right on the first slide bar 21, so that the first rack 20 drives the first gear 19 to reciprocate, and the first gear 19 drives the paddle shaft 35 to reciprocate, so that the paddle 34 can poke the brush end of the brush rod 26, so that the scraps attached to the brush can be shaken off. The scraps dropped by the brush end of the brush rod 26 are adsorbed under the negative pressure generated by the exhaust fan 18. Moreover, since the brush rod 26 is also rotating while being lifted and lowered, the shifting range of the paddle plate 34 and the adsorption range of the adsorption head 36 are both expanded, so that the scraps attached to the brush end of the brush rod 26 can be evenly cleaned and collected, so that when the brush rod 26 dredges the next group of sieve holes 8, the scraps attached to the previous group will not be brought into the hole wall of the next group of sieve holes 8, and the recycling effect is good.

As shown in FIG. 1 , a collection box 6 for collecting scraps is placed at the right end of the transmission chamber 1 .

Specifically, the collection box 6 is placed at the right end of the transmission chamber 1, and the scraps transported by the conveyor belt 2 can accurately fall into the collection box 6 for collection. After the collection is completed, personnel manually carry and transfer it.

As shown in Figures 2 and 3, a second motor 13 is fixedly connected to the middle of the front end surface of the frame 12, and the output end of the second motor 13 is fixedly connected to the screen 5 through a rotating shaft. A baffle 15 is rotatably provided on the right end of the screen 5. A third motor 14 is fixedly connected to the right side of the front end surface of the screen 5, and the output end of the third motor 14 is fixedly connected to the baffle 15 through a rotating shaft.

Specifically, after all the scraps with small particle sizes have been collected, the second motor 13 can be started to drive the screen 5 to rotate clockwise, so that the screen 5 is tilted, and the remaining scraps with large particle sizes are all moved to the right and fit with the left end of the baffle 15, and then the third motor 14 is turned on to drive the baffle 15 to rotate counterclockwise, so that an opening is formed between the baffle 15 and the right end of the screen 5, so that the scraps with large particle sizes fall to the upper end of the conveyor belt 2 under the action of gravity, and the conveyor belt 2 drives the scraps with large particle sizes to move to the right and fall into the collecting box 6, so that the scraps with large particle sizes can be collected.

As shown in Figure 10, the connection between the right rotating roller 55 and the transmission chamber 1 is fixedly connected with the third bevel gear 40 through a rotating shaft. The fourth bevel gear 41 and the second eccentric block 49 are arranged on the right side of the front end of the transmission chamber 1 through the rotation of the rotating shaft. The fourth bevel gear 41 and the third bevel gear 40 are meshed with each other. The third slide bar 51 is slidably connected to the right end of the front side of the transmission chamber 1. The front end of the third slide bar 51 is fixedly connected to the first extrusion plate 53. The first extrusion plate 53 can be displaced under the rotation of the second eccentric block 49. The front end of the upper third slide bar 51 is sleeved with a second spring 52. The front end of the second spring 52 is fixedly connected to the first extrusion plate 53. The rear end of the second spring 52 is fixedly connected to the transmission chamber 1. The rear end of the third slide bar 51 is fixedly connected to the displacement plate 50. The displacement plate 50 is slidably connected with sliding columns 43 on both sides. The left end of the sliding column 43 is fixedly connected to the brush plate 42. The brush end of the brush plate 42 is fitted with the right end of the conveyor belt 2.

Specifically, when the rotating roller 55 drives the conveyor belt 2 to operate, the third bevel gear 40 drives the fourth bevel gear 41 to rotate, which can make the second eccentric block 49 rotate. The second eccentric block 49 is constantly in contact with the first extrusion plate 53, so that the first extrusion plate 53 drives the third slide bar 51 to slide, and resets under the action of the second spring 52, so that the displacement plate 50 slides back and forth. When the displacement plate 50 slides back and forth, the brush end of the brush plate 42 can be used to clean the surface of the conveyor belt 2 where the scraps fall, so as to avoid the scraps adhering to the surface of the conveyor belt 2, improve the efficiency of the scraps falling, and also ensure the cleanliness of the surface of the conveyor belt 2 for easy recycling.

As shown in Figure 10, the connection between the second eccentric block 49 and the transmission chamber 1 is fixedly connected with the sixth bevel gear 48 through a rotating shaft, and a bump rod 46 is rotatably set at the right end of the front side of the transmission chamber 1. The front end of the bump rod 46 is sleeved and fixedly connected with the fifth bevel gear 47. The fifth bevel gear 47 and the sixth bevel gear 48 are meshed with each other. The bump rod 46 is inserted and slidably connected with a groove cylinder 56. The groove cylinder 56 is rotatably connected to the displacement plate 50, and the rear end of the groove cylinder 56 is sleeved and fixedly connected with the first eccentric block 44. The right end of the sliding column 43 is fixedly connected to the second extrusion plate 54, and the right end of the front sliding column 43 is sleeved with a first spring 45. The left end of the first spring 45 is fixedly connected to the displacement plate 50, and the right end of the first spring 45 is fixedly connected to the second extrusion plate 54.

Specifically, when the brush plate 42 cleans the surface of the conveyor belt 2, the sixth bevel gear 48 drives the fifth bevel gear 47 to rotate, which can rotate the lug rod 46. When the brush plate 42 moves forward and backward, the lug rod 46 and the groove cylinder 56 slide relative to each other, and the first eccentric block 44 continues to rotate. The first eccentric block 44 continuously squeezes the second squeezing plate 54, and the second squeezing plate 54 drives the sliding column 43 to move, and then resets under the action of the first spring 45, so that the brush plate 42 can move left and right. The brush plate 42 vibrates in the direction so that it intermittently contacts the surface of the conveyor belt 2. When the brush plate 42 contacts the surface of the conveyor belt 2, the scraps are cleaned. When the brush plate 42 is away from the conveyor belt 2, a gap is formed between the brush plate 42 and the conveyor belt 2, and the scraps can pass through the gap. Moreover, since the brush plate 42 vibrates continuously, the scraps will not be blocked by the brush part of the brush plate 42 or adhere to the upper end of the brush plate 42, so the scraps can fall smoothly into the collection box 6.

As shown in Figures 1 and 1, a first cover body 57 and a second cover body 58 are fixedly connected to one end of the transmission cavity 1. The first cover body 57 is rotationally connected to the fourth bevel gear 41 via a rotating shaft, one side of the second cover body 58 is rotationally connected to the second eccentric block 49 via a rotating shaft, one end of the second cover body 58 is slidingly connected to the third sliding rod 51, and one end of the second cover body 58 is rotationally connected to the bump rod 46.

Specifically, the first cover body 57 and the second cover body 58 are used to wrap the local transmission components to prevent dust and impurities from adhering to the transmission components and affecting the transmission work thereof.

Working principle: first, a placement slot is opened on the ground on one side of the paper product processing equipment, and the device is placed in the placement slot. The scraps are discharged and fall to the upper end of the screen 5. Then, under the action of the electromagnetic vibrator 16, the screen 5 is vibrated, and the small-particle scraps will fall to the upper end of the conveyor belt 2 through the screen hole 8. Then, under the clockwise rotation of the rotating roller 55, the conveyor belt 2 is operated to transport the small-particle scraps to the right. When the small-particle scraps move to the rightmost end of the conveyor belt 2, they will fall into the collection container, and the small-particle scraps can be collected. When the screen 5 is working, the screen hole 8 may be blocked by small-particle scraps. In order to avoid this situation, when the screen 5 is working, the housing 25 can be driven to slide left and right on the second slide bar 39, so that the multiple groups of brush rods 26 move and align with the multiple groups of screen holes 8 in sequence, and the brush rods 26 coincide with the axis of the screen hole 8, and then the brush rods 26 are driven to rise and rotate to be inserted into the screen hole 8, and the top end of the brush rod 26 is used to dredge the blocked scraps, and under the action of the rotation of the brush end, the scraps attached to the hole wall are cleaned, so that the screen hole 8 can be dredged. The brush rod 26 is provided with a plurality of paddle plates 34 for reciprocating rotation, and the paddle plates 34 are provided with a plurality of paddle plates 34 for reciprocating rotation. The paddle plates 34 are ... The scraps can be sucked into the dust box 17 again through the suction head 36 for collection, which can avoid the brush rod 26 from attaching the attached scraps to the next group of sieve holes 8 again. Therefore, while using the brush rod 26 to dredge the sieve holes 8, the brush rod 26 itself can also be kept clean, and the recycling effect is good. When the screening work is completed, there is no small-particle scraps on the upper end of the sieve 5. At this time, the dust box 17 is opened, the small-particle scraps collected inside are taken out, poured into the collection container, and transported to the collection container by the conveyor belt 2. The small-particle scraps in the conveyor belt 2 are mixed to complete the collection of the small-particle scraps, and then the personnel carry and transfer them, and then place the collection container of the cavity at the right end of the conveyor cavity 1 again, ready to collect the large-particle scraps. At this time, the scraps remaining on the upper end of the screen 5 are all large-particle scraps. The screen 5 can be driven to rotate clockwise to tilt the screen 5, so that the large-particle scraps slide to the upper end of the conveyor belt 2 under the action of gravity, and then move to the right with the conveyor belt 2 and fall into the collection container again. After loading is completed, it is moved again. The conveyor belt 2 is moved by the rotating roller 55, and the third bevel gear 40 drives the fourth bevel gear 41 to rotate, so that the second eccentric block 49 rotates. The second eccentric block 49 is constantly in contact with the first extrusion plate 53, so that the first extrusion plate 53 drives the third slide bar 51 to slide, and resets under the action of the second spring 52, so that the displacement plate 50 slides back and forth. When the displacement plate 50 slides back and forth, the brush end of the brush plate 42 can be used to clean the conveyor belt 2 where the scraps fall. The surface of the conveyor belt 2 can be cleaned to avoid the situation that the scraps are attached to the surface of the conveyor belt 2, improve the efficiency of the scraps falling, and ensure the cleanliness of the surface of the conveyor belt 2 for easy recycling. The sixth bevel gear 48 drives the fifth bevel gear 47 to rotate, which can make the protrusion rod 46 rotate. When the brush plate 42 moves forward and backward, the protrusion rod 46 and the groove cylinder 56 slide relative to each other, and the first eccentric block 44 continues to rotate, and the first eccentric block 44 continuously squeezes the second squeezing plate 54, and the second squeezing plate 54 drives the sliding column 43 to move, and then the first spring 45 , the brush plate 42 is reset under the action of , so that the brush plate 42 can vibrate in the left and right directions, so that the brush plate 42 is in intermittent contact with the surface of the conveyor belt 2. When the brush plate 42 is in contact with the surface of the conveyor belt 2, the scraps are cleaned. When the brush plate 42 is away from the conveyor belt 2, a gap will be formed between the brush plate 42 and the conveyor belt 2, and the scraps can pass through the gap. Moreover, since the brush plate 42 vibrates continuously, the scraps will not be blocked by the brush part of the brush plate 42 or adhere to the upper end of the brush plate 42, so that the scraps can fall smoothly into the collection box 6.
