TECHNICAL FIELD

[0001] The application relates to the field of paperboard processing technology, in particular to a paperboard processing waste collecting device. BACKGROUND

[0002] At present, corrugated paperboard is widely used as the packaging of various commodities due to its light weight, low price, simple manufacturing, wide application and recycling.

[0003] For example, a waste recovery device for white paperboard production in application No. CN202121374171.2 has the following disadvantages:

[0004] The above patent crushes the waste by setting a crushing roller, and discharges the crushed waste into the compression mechanism through the cooperation of the discharge mechanism and the discharge hole. However, the above device ignores the fact that the lengths of paperboard waste are different, which may be stuck in the funnel and cannot go down, thereby causing blockage and affecting the collection efficiency. The above device cannot solve this problem, and manual cleaning is the only way, which may cause injury to the operator due to improper operation if the device does not stop, and may affect the collection efficiency if the device stops. CONTENT OF THE UTILITY MODEL

[0008] The horizontal extrusion mechanism comprises a square bin arranged on the side wall of the inner cavity of the collecting bin, two identical first single pulleys are longitudinally and symmetrically connected to the side of the conveyor belt through the square bin, a first belt is slidably arranged in the middle groove of the outer ring surface of the two first single pulleys, and a double pulley connected with the side wall of the collecting bin is slidably arranged on the side of the first belt away from the first single pulley.

[0010] By adopting the above technical scheme, the paperboard waste is transmitted and collected by the cooperation of the conveying belt and the collecting bin, and the paperboard waste in the conveying belt is pushed into the collecting bin through the reciprocating cooperation of the scraper and the transverse extrusion mechanism, and then the paperboard waste is pushed into the shearing bin through the vertical extrusion mechanism, and then the paperboard waste cut by the shearing bin falls into the compression bin for compression, so as to reduce the volume of the paperboard waste and the compressed paperboard waste can be stacked.

[0011] Preferably, the transverse extrusion mechanism further comprises a fixed block fixedly arranged at the two ends of the first belt, a rotating shaft is rotatably connected to one side of the fixed block, and a moving limiting block fixedly connected with the scraper is arranged on the side of the rotating shaft away from the fixed block.

[0012] By adopting the above technical scheme, the fixed block can drive the rotating shaft and the moving limiting block to move together with the first belt, and the moving limiting block is fixedly connected with the scraper, so that the moving limiting block can always keep a downward state when moving with the scraper under the assistance of the rotating shaft, and the scraper will not be turned over when moving to the upper part of the first belt, thereby avoiding the need to increase the height of the upper part of the collecting bin.

[0013] Preferably, a transverse guide groove in sliding connection with the moving limiting block is arranged at the lower part of the first belt, and two fixed seats fixedly connected with the side wall of the square bin are arranged at the two ends of the transverse guide groove.

[0014] By adopting the above technical scheme, the transverse guide groove can limit the scraper, so that the scraper will not be affected by the paperboard waste and thus cannot push the paperboard waste.

[0015] Preferably, the vertical extrusion mechanism further comprises a roller fixedly arranged on the outer surface of the lower pressing rod away from the telescopic rod, the roller is slidingly arranged in an elliptical sliding rail, an elliptical sliding groove in sliding connection with the lower pressing rod is fixedly arranged on the side of the elliptical sliding rail away from the roller, and the elliptical sliding groove is fixedly arranged on the side wall of the collecting bin cavity.

[0017] Preferably, a second belt is slidably arranged in the second single-pulley outer ring surface middle groove, and the second belt is slidably connected with the outer ring surface groove of the double-pulley away from the first belt on the side away from the second single-pulley.

[0018] By adopting the above technical scheme, the second belt single-pulley can provide power for the second belt, and further provide power for the double-pulley, so that the power transmission is more reasonable.

[0019] Preferably, an auxiliary telescopic spring is fixedly arranged inside the telescopic rod retraction end.

[0020] By adopting the above technical scheme, the spring can assist the telescopic rod retraction end to retract and extend when the telescopic rod retraction end moves according to the elliptical sliding groove, which is a labor-saving auxiliary structure.

[0021] Preferably, the second single-pulley is fixedly connected with the alternating-current motor output end arranged on the middle part of the outer surface of the collection bin on the side away from the telescopic rod.

[0022] By adopting the above technical scheme, the fixed connection of the alternating-current motor output end and the second belt single-pulley can provide sufficient power for the second belt single-pulley to drive the operation of the horizontal extrusion mechanism and the vertical extrusion mechanism.

[0023] Preferably, triangular limiting plates capable of limiting the abutment of the scraper are fixedly arranged on both sides of the side feeding port.

[0024] By adopting the above technical scheme, the triangular limiting plates abut against the scraper, which can guide and limit the scraper, prevent the scraper from turning upward or to one side when contacting the paperboard waste during the downward movement due to the shaft, and thus cannot push the paperboard waste.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. The horizontal extrusion mechanism cooperates with the scraper to enable the scraper to reciprocate, thereby pushing the paperboard waste conveyed into the collection bin through the side feeding port, thereby avoiding blockage at the side feeding port due to long paperboard waste or excessive waste;

[0027] 2. The lower pressing rod in the vertical extrusion mechanism cooperates with the elliptical sliding groove to extrude the paperboard waste conveyed through the upper feeding port and the side feeding port into the shearing bin, so that the shearing bin can better shear the paperboard waste, and then the sheared waste falls into the compression bin for compression.

[0039] The following will be described in detail in combination with the accompanying drawings. Figure 1 - Figure 7 The present application will be further described in detail.

[0040] The embodiment of the present application discloses a paperboard processing waste collecting device.

[0041] Reference Figure 1 , Figure 2The application discloses a paperboard processing waste collecting device, which comprises a compression bin 1 placed on the ground, a shearing bin 2 fixed on the upper part of the compression bin 1, a collecting bin 4 fixed on the upper part of the shearing bin 2, a conveying belt 3 for conveying waste paperboard arranged on one side of the collecting bin 4, a side feeding port 10 arranged on one side of the collecting bin 4, and an upper feeding port 11 for collecting waste paperboard arranged on the upper part of the collecting bin 4 away from the shearing bin 2, wherein two scrapers 8 are arranged in the inner cavity of the side of the collecting bin 4, the two scrapers 8 are the same in structure and are arranged in an up-down staggered mode to avoid cross influence on the movement track, and two triangular limiting plates 9 are fixed on the two sides of the opening of the side feeding port 10.

[0042] The conveying belt 3 is responsible for conveying the paperboard waste to the inner cavity of the collecting bin 4 through the side feeding port 10, and then the waste caused by paperboard cutting is pushed into the inner part of the collecting bin 4 through the reciprocating movement of the scrapers 8, so that the blockage of the opening of the side feeding port 10 caused by the uneven length or excessive quantity of the waste is avoided, and the upper feeding port 11 of the upper part of the collecting bin 4 can simultaneously collect the waste paperboard with the side feeding port 10, thereby increasing the collection efficiency.

[0043] It should be noted that the compression bin 1, the shearing bin 2 and the conveying belt 3 are prior art, and the structural principles are not described here.

[0044] Refer to Figure 3 , Figure 4 , Figure 5, two ends of the two scrapers 8 are symmetrically provided with two transverse extrusion mechanisms 5, and the two transverse extrusion mechanisms 5 are the same in structure and installation mode, and the transverse extrusion mechanism 5 comprises a square bin 51 formed in the inner cavity side wall of the collecting bin 4 close to the side inlet 10, and the square bin 51 is provided with two first single pulleys 52 symmetrically from top to bottom on the side wall of the conveying belt 3, and the two first single pulleys 52 are the same in structure and are rotatably connected with the side wall of the square bin 51, and the inner surface of the groove in the middle of the outer ring surface of the two first single pulleys 52 is slidably connected with the outer surface of the first belt 54, and the first belt 54 is rotatably connected with the outer ring surface groove of the double pulley 7 away from the side wall of the collecting bin 4, and the double pulley 7 is rotatably arranged in the middle of the upper side walls of the inner cavity of the collecting bin 4 and symmetrically arranged, and the lower part of the first belt 54 is fixedly connected with the upper surface of the fixed block 56 on the lower surface of the side inlet 10, and the upper part of the first belt 54 is provided with a second fixed block 56 on the upper surface of the double pulley 7, and the two fixed blocks 56 are the same in structure and are rotatably connected with the shaft 57 away from the side wall of the collecting bin 4, and the two shafts 57 are fixedly connected with the side surface of the moving limiting block 58 away from the fixed block 56, and the side surfaces of the two moving limiting blocks 58 away from the shaft 57 are respectively fixedly connected with the upper part of the side surface of the scraper 8, and the lower part of the first belt 54 is provided with a transverse guide groove 55 with a height greater than that of the moving limiting block 58, and the two ends of the transverse guide groove 55 are fixedly provided with fixed seats 53, and the side surfaces of the two fixed seats 53 away from the transverse guide groove 55 are fixedly connected with the side wall of the square bin 51, and the inner cavity surface of the transverse guide groove 55 is smooth and can accommodate the moving limiting block 58 to slide therein.

[0045] The double pulley 7 is connected with the first belt 54, and the first belt 54 is connected with the two symmetrically arranged first single pulleys 52, so that when the double pulley 7 rotates, the first belt 54 can slide in the groove of the double pulley 7, thereby driving the two first single pulleys 52 to rotate together, and when the first belt 54 rotates, the fixed block 56 fixedly connected therewith can move, thereby driving the shaft 57, the moving limiting block 58 and the scraper 8 to move together, and when the fixed block 56 moves to the upper part of the first belt 54, the scraper 8 can always keep the lower end downward under the action of its own weight and the shaft 57, and when the scraper 8 moves to the side inlet 10, the scraper 8 will not be reversed due to the blockage of the paper shell waste, thereby causing the paper shell waste to be unable to be pushed, and when the scraper 8 moves to the lower part of the first belt 54, the transverse guide groove 55 guides and limits the scraper 8, so that the two scrapers 8 can alternately push the paper shell waste.

[0046] It should be noted that the inner surface of the transverse guide groove 55 is set to a smooth surface and can accommodate the movable limit block 58 to slide inside and provide a limit for the movable limit block 58, preventing the movable limit block 58 from rotating due to the reaction force of the paper shell waste, thereby being unable to push the paper shell waste.

[0047] Reference Figure 3 、 Figure 6 、 Figure 7 Two vertical extrusion mechanisms 6 are symmetrically arranged on the side of the inner cavity of the collecting bin 4 away from the horizontal extrusion mechanism 5, and the two vertical extrusion mechanisms 6 have the same structure and installation method, and the vertical extrusion mechanism 6 includes a second single pulley 61 rotatably arranged in the middle of the side wall of the inner cavity of the collecting bin 4 located below the upper feed port 11, and the second single pulley 61 is fixedly connected to the output end of the AC motor 12 in the middle of the side away from the telescopic rod 62, and the output end of the AC motor 12 movably passes through the side wall of the collecting bin 4, and the fixed base of the AC motor 12 is fixedly connected to the middle of the outer surface of the collecting bin 4, and the inner surface of the groove in the middle of the outer annular surface of the second single pulley 61 is slidingly arranged with the outer surface of the second belt 68, and the outer surface of the second belt 68 away from the second single pulley 61 is slidingly connected with the inner surface of the groove on the outer annular surface of the double pulley 7 away from the first belt 54, and the second single pulley 61 is far away The side away from the side wall of the collecting bin 4 is fixedly connected to the middle of the telescopic rod 62, and the retracted ends on both sides of the telescopic rod 62 are fixedly connected to two springs 67 for auxiliary telescopic action, and the protruding ends at both ends of the telescopic rod 62 are rotatably provided with two down-pressing rods 63, and the two down-pressing rods 63 have the same structure and the length of the two down-pressing rods 63 runs through the entire inner cavity of the collecting bin 4, and the outer ring surface of the down-pressing rod 63 away from one end of the telescopic rod 62 is fixedly penetrated, and the outer ring surface of the roller 66 and the inner surface of the elliptical slide 65 are slidingly arranged, and the surface of the elliptical slide 65 away from the roller 66 is fixedly connected to the upper part of the surface of the elliptical slide 64, and the elliptical slide 64 away from the elliptical slide rail 65 is fixedly connected to the side wall of the collecting bin 4, and the inner cavity surface of the elliptical slide 64 is set to a smooth surface and is movably connected to the outer ring surface of the down-pressing rod 63 away from the roller 66.

[0048] The rotating of the second single pulley 61 is driven by the output end of the alternating current motor 12, and then drives the second belt 68 to rotate and drive the double pulley 7 to rotate, so that the whole transverse extrusion mechanism 5 operates, and at the same time, the second single pulley 61 rotates to drive the telescopic rod 62 to rotate together, and then drives the lower pressing rod 63 at both ends of the telescopic rod 62 to rotate up and down in the inner cavity of the collecting bin 4, so as to press the paperboard waste down until it falls into the shearing bin 2. When the lower pressing rod 63 rotates, it is limited by the oval sliding groove 64, so that it slides according to the predetermined track, and when the lower pressing rod 63 slides in the oval sliding groove 64, the roller 66 fixed to the lower pressing rod 63 slides on the inner surface of the oval sliding rail 65 and rotates, thereby driving the lower pressing rod 63 to slide while rotating, thereby preventing the paperboard waste from winding on the lower pressing rod 63 due to being too long, and then moving with the lower pressing rod 63.

[0049] It should be noted that the alternating current motor 12 is a prior art, which needs to be connected with a controller or an external switch, but since it is a prior art, it will not be described in detail here.

[0050] The implementation principle of the paperboard processing waste collecting device is as follows: first, open the control switch, so that the output end of the alternating current motor 12 rotates, and then drives the second single pulley 61 to rotate, and at the same time, the second single pulley 61 drives the telescopic rod 62 to rotate together with the second belt 68.

[0051] The rotation of the second belt 68 drives the double pulley 7 to rotate, and then drives the first belt 54 to rotate, and the rotation of the first belt 54 drives the two first single pulleys 52 to rotate together, and then drives the two fixed blocks 56 fixed to the first belt 54 to move together, so that the rotating shaft 57, the moving limiting block 58 and the scraper 8 move together. When the scraper 8 moves to the side inlet 10, the scraper 8 is blocked by the triangular limiting plate 9, so that the scraper 8 does not rotate in the opposite direction due to the blockage of the paper shell waste, thereby preventing the paper shell waste from being pushed. When the scraper 8 moves to the lower part of the first belt 54, the transverse guide groove 55 guides and limits the movement of the scraper 8, so that the two scrapers 8 can alternately push the paper shell waste into the inner cavity of the collecting bin 4.

[0052] When the telescopic rod 62 rotates, the lower pressing rods 63 at both ends can rotate up and down in the inner cavity of the collecting bin 4, thereby pressing the paperboard waste in the inner cavity of the collecting bin 4 downward until the paperboard waste falls into the shearing bin 2. The rotation of the lower pressing rod 63 can slide in the predetermined track of the oval sliding groove 64. When the lower pressing rod 63 slides in the oval sliding groove 64, the roller 66 fixedly connected with the lower pressing rod 63 slides and rotates on the inner surface of the oval sliding rail 65, thereby driving the lower pressing rod 63 to slide in the predetermined track while also being able to rotate by itself, thereby preventing the paperboard waste from winding on the lower pressing rod 63 due to being too long. The entire vertical extrusion mechanism 6 can also extrude the paperboard waste falling into the inner part of the collecting bin 4 from the upper feeding port 11, thereby preventing the paperboard waste from being blocked due to being too much.

[0053] The above is only an optional embodiment of the present disclosure and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
