Description

Technical Field

[0001] The invention relates to the technical field of papermaking related devices, and in particular to a papermaking raw material lifting device. Background Art

[0002] Modern papermaking mainly uses wood as raw material to make paper, which involves stripping the bark from logs, chopping them into small pieces, chopping them up, and mixing them with water to make pulp. Chemicals are then added to the pulp and the mixture is boiled in a pressurized container until the cellulose fibers are separated from the lignin that binds them together. The pulp is further washed, filtered, purified, and various additives are added before it is spread on a filter screen and passed through rollers to squeeze out the water, forming a continuous paper strip. Finally, after drying and flattening, the finished paper is rolled into rolls and shipped to processing plants.

[0003] Before sending the wood into the mixing tank to mix with water, the long trunks are chopped into blocks in advance. Usually, trees of this size are directly put into the mixing tank via a conveyor belt, and it takes a long time to dissolve in water to form pulp. Therefore, a method can be designed to further cut the block trunks into smaller pieces while lifting the wood chips, so as to improve the subsequent pulp manufacturing efficiency. At the same time, when the wood chips are fed into the mixing tank, continuous quantitative feeding is required to ensure the continuity of pulp preparation. Summary of the invention

[0004] The purpose of the present invention is to provide a papermaking raw material lifting device, which has the technical effects of cutting wood into smaller specifications, controlling the cutting feed amount, and ensuring the cutting effect.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: it includes a pressing mechanism, a pushing mechanism, a shredding mechanism and a feeding mechanism connected in sequence, the pressing mechanism includes a conveyor belt rotatably connected to a supporting vertical plate, a pressing roller is rotatably connected in a supporting frame above the conveyor belt near the pushing mechanism, and pressing blocks are evenly arranged on the pressing roller and the conveyor belt, the pushing mechanism includes a pushing plate, the pushing plate is lifted and slidably connected to a screw rod and a sliding rod, the screw rod and the sliding rod are vertically located on the upper end surface of a sliding plate, the sliding plate is connected to the piston rod end of a cylinder located on the bottom surface of a pushing bottom plate, the shredding mechanism includes a cutter, the cutter is perpendicular to the shredding belt, and the cutter is intermittently slidably connected to the shredding side plate.

[0006] By adopting the above technical scheme, first the breaking mechanism crushes the initial trees into long strips of trunks, which are transported to the pushing bottom plate and then transported to the shredding belt of the shredding mechanism under the push of the pushing plate. Then the cutter chops the long strips of trunks into small pieces during movement, and finally the pieces are transported to other places through the unloading mechanism. By setting the breaking mechanism and the shredding mechanism, the wood can be cut into pieces of suitable size, thus shortening the subsequent pulp preparation time. By setting the pushing mechanism, the amount of trunks entering the shredding mechanism at a single time can be controlled to avoid the large amount affecting the shredding result and also avoid affecting the uniformity of subsequent unloading.

[0007] The present invention is further configured as follows: a square plate is vertically fixed to the end of the pushing base plate near the shredding mechanism, and a slide groove 1 is mirror-set on both sides of the square plate, a connecting rod 1 is slidably connected in the slide groove 1, short rods are vertically fixed at both ends of the connecting rod 1, the other ends of the two short rods are connected to the connecting rod 2, and the two short rods on the same side above and below are respectively slidably connected to the slide grooves 2 at both ends of the two connecting rods 3, the two connecting rods 3 are parallel and the middle parts are rotatably connected to the square plate, a guide rod is vertically fixed to the side surface of the connecting rod 2 near the breaking mechanism, the other ends of the two guide rods vertically penetrate the two sides of the pushing plate, and the side surface of the connecting rod 2 near the shredding mechanism is vertically fixed on both sides of the isolation plate, and the isolation plate is located between the pushing base plate and the shredding belt in the shredding mechanism.

[0008] By adopting the above technical scheme, when the screw rod rotates, the push plate descends, blocking the long strips of tree trunks crushed in the conveyor belt from entering the push bottom plate; when the stacking plate descends, the push plate drives the guide rod to descend; since the guide rod is fixed to the side of the connecting rod two, the connecting rod one close to the crushing mechanism descends; since the two connecting rods one are connected by the connecting rod three, the connecting rod three rotates at this time, and the connecting rod one close to the shredding mechanism rises; at this time, the two connecting rods one and the connecting rod three form a seesaw connection; and since the end of the connecting rod three is provided with the slide groove two, and the short rod slides in the slide groove one within a limited position, and the connecting rod one slides in the slide groove two, the connecting rod one and the connecting rod two maintain the vertical lifting state during lifting; therefore, when the guide rod descends, the isolation plate rises, which is convenient for the push plate When moving toward the shredding mechanism, the tree trunks at the pushing point are smoothly pushed onto the shredding belt. The isolation plate acts as a barrier after all the long tree trunks can enter the shredding belt, preventing the tree trunks from being shredded when they are exposed to the outside, which is prone to danger. Then, when the cylinder drives the sliding plate to approach the shredding mechanism, the pushing plate will push all the tree trunks already on the pushing bottom plate into the shredding belt. After the pushing is completed, the screw is reversed, the pushing plate rises, the isolation plate drops, and then the pushing plate retreats. At this time, the tree trunks in the breaking mechanism are transported to the pushing bottom plate, and due to the setting of the isolation plate, the vertical rod will not be pushed into the shredding mechanism. By setting the pushing plate, the tree trunks can be quantitatively transported to be shredded, avoiding the generation of more or less wood chips, which affects the preparation of pulp.

[0009] The present invention is further configured as follows: the number of the cutters is plural and they are fixed parallel and vertically on the push plate; a push rod is fixed on the outer side of the push plate; the bottom of the push rod is vertically fixed to one end of a connecting rod; the other end of the connecting rod passes through an open groove in a shredding side plate parallel to the shredding belt; a spring is provided on an outer sleeve of the connecting rod in the open groove; the spring drives the push rod to approach the shredding belt; a driving component is provided in the shredding belt to drive the connecting rod to slide close to the shredding side plate.

[0010] The present invention is further configured as follows: the driving assembly includes a driving rod 1 connected to the connecting rod, the other end of the driving rod is vertically fixed to the long bottom side of the wedge plate 1, the wedge plate 1 is a right-angled trapezoid, the hypotenuse of the wedge plate 1 cooperates with the wedge plate 2, the wedge plate 2 is a right-angled trapezoid, the high side of the wedge plate 2 is vertically fixed with the driving rod 2, the other end of the driving rod 2 is fixed at the connection point of the sliding plate 1, when the sliding plate 1 is close to the shredding mechanism, the wedge plate 2 is close to fit with the wedge plate 1 and drives the wedge plate 1 to approach the shredding side plate.

[0011] By adopting the above technical scheme, the number of cutters is several, and the cutters are perpendicular to the running direction of the tree trunk. Then, when the tree trunk moves on the shredding belt, the tree trunk can be chopped into wood chips. When the sliding plate 1 is close to the shredding mechanism, the pushing plate just pushes the tree trunk onto the shredding belt. At the same time, the bevel of the wedge block 2 is close to the bevel of the wedge block 1, driving the wedge block 1 to be close to the shredding side plate, that is, the cutter retreats from the shredding belt to the shredding side plate. The cutter retreats to facilitate the pushing of the tree trunk onto the shredding belt. Further, when the sliding plate 1 is away from the shredding mechanism, the wedge plate 2 retreats close to the breaking mechanism, and the wedge block 1 drives the cutter to cross the shredding belt to complete the shredding of the tree trunk. During this period, the isolation plate is in a falling state, which blocks the shredding mechanism from the pushing mechanism to ensure the smooth completion of the crushing of the tree trunk. The whole process is jointly designed to ensure the quantitative shredding of the tree trunk.

[0012] The present invention is further configured as follows: the unloading mechanism includes a unloading hopper, the discharge port of the unloading hopper is located above the discharge belt, stirring rods are fixed at intervals at the lower part of the stirring shaft located in the unloading hopper, the stirring shaft passes through the supporting cross plate, a driven gear is fixed to the upper end of the stirring shaft, and the driven gear is externally meshed with a driving gear rotatably connected to the supporting cross plate.

[0013] By adopting the above technical solution, the driving gear rotates to drive the driven gear to rotate, and then the stirring shaft rotates to drive the stirring rod to stir the wood chips, homogenize the wood chips, and ensure the stable and uniform output amount.

[0014] The present invention is further configured as follows: the rotating shaft at the center of the crushing roller is rotatably connected to the circular slide, the circular slide passes through the slide groove three which is slidably connected to both sides of the support frame, the two ends of the circumferential surface of the crushing roller are symmetrically concavely provided with annular grooves, and an arc-shaped slide is limitedly slidably connected in the annular groove, the top surface of the arc-shaped slide is hinged to the bottom of the connecting vertical rod, the top of the connecting vertical rod passes through the pressure plate, and the outer sleeve of the connecting vertical rod located between the pressure plate and the arc-shaped slide is provided with spring two, and the spring two drives the crushing roller to approach the conveyor belt.

[0015] By adopting the above technical scheme, due to the different thicknesses of trees, when they are transported between the breaking rollers of the conveyor belt, the breaking rollers need to be lifted to a certain height, driving the arc-shaped slide plate to slide in the annular groove, the connecting vertical rod is lifted up, and the second spring is compressed. The second spring and the breaking roller both act on the tree to crush the tree into long strips. At the same time, pressure blocks are evenly arranged on the breaking roller and the conveyor belt to promote the effect of crushing the tree.

[0016] The present invention is further configured as follows: the tooth width of the driven gear is relatively large, and a connecting plate frame is sleeved on the stirring shaft between the stirring rod and the driven gear, the stirring shaft passes through the connecting plate frame for limiting rotation, and the connecting plate frame is provided with open grooves on opposite sides, and rollers are slidably connected in the open grooves, and the center rod at the center of the roller passes through the sliding grooves four of the rods on the opposite sides of the U-shaped pull rod, the pull rod is sleeved and fixed on the outside of the driving rod three, and the driving rod three is coaxially fixedly connected to the output shaft of the driving motor, and the bottom of the stirring shaft is vertically fixed to the discharging circular plate at the bottom of the lower hopper, and the discharging circular plate is rotatably connected to the discharging port of the discharging hopper.

[0017] By adopting the above technical solution, after the stirring shaft has stirred for a certain period of time, the driving motor is started, the driving rod rotates, and the U-shaped pull rod rotates clockwise, then the center rod drives the roller to slide in the connecting plate frame, the connecting plate frame descends, the discharging circular plate descends, and separates from the lower hopper, and the wood chips fall from the lower hopper to the discharging belt. When discharging, the tree trunks are being chopped in the shredding mechanism. After the wood chips are discharged, the wood chips in the shredding mechanism fall into the lower hopper, forming a stable and continuous discharging.

[0018] The present invention is further configured as follows: vertical baffles are vertically fixed on opposite sides of the pusher bottom plate, and square holes are provided in the vertical baffles.

[0019] By adopting the above technical solution and the design of the square hole, the movement space of the push plate and the guide rod is convenient.

[0020] The present invention is further configured as follows: a side of the cutter away from the push plate is configured with a triangular cross section.

[0021] By adopting the technical solution, the flatness of the chopped tree trunks is ensured.

[0022] The present invention is further configured as follows: the driving gear is coaxially and fixedly connected to the output shaft of the stirring motor.

[0023] The beneficial effects of the present invention are as follows: first, the crushing mechanism crushes the initial trees into long strips of trunks, which are then conveyed to the pushing bottom plate and then conveyed to the shredding belt of the shredding mechanism under the push of the pushing plate. Subsequently, the cutter shreds the long strips of trunks into small pieces during movement, which are finally conveyed to other places through the unloading mechanism. By arranging the crushing mechanism and the shredding mechanism, the wood can be cut into wood chips of suitable sizes, thus shortening the subsequent pulp preparation time. By arranging the pushing mechanism, the amount of trunks entering the shredding mechanism at a single time can be controlled, thus avoiding the large amount affecting the shredding result and also avoiding affecting the uniformity of subsequent unloading.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment, a papermaking raw material lifting device, such as Figure 1-6 As shown, it includes a pressing mechanism 1, a pushing mechanism 2, a shredding mechanism 3 and a feeding mechanism 4 connected in sequence. The pressing mechanism 1 includes a conveyor belt 101 rotatably connected to a supporting vertical plate. A pressing roller 102 is rotatably connected in a supporting frame above the conveyor belt 101 near the pushing mechanism 2. Pressing blocks 103 are evenly arranged on the pressing roller 102 and the conveyor belt 101. The pushing mechanism 2 includes a pushing plate 201. The pushing plate 201 is lifted and slidably connected to a screw rod 202 and a slide rod 203. The screw rod 202 and the slide rod 203 are vertically located on the upper end surface of a sliding plate 204. The sliding plate 204 is connected to the piston rod end of a cylinder 206 located on the bottom surface of a pushing bottom plate 205. The shredding mechanism 3 includes a cutter 301. The cutter 301 is perpendicular to the shredding belt 302. The cutter 301 is intermittently slidably connected to the shredding side plate 303.

[0034] By adopting the above technical scheme, the breaking mechanism 1 first crushes the initial tree into long strips of trunks, which are then transported to the pushing bottom plate 205 and then transported to the shredding belt 302 of the shredding mechanism 3 under the push of the pushing plate 201. Then, the cutter 301 chops the long strips of trunks into small pieces during movement, and finally the pieces are transported to other places through the unloading mechanism 4. By setting the breaking mechanism 1 and the shredding mechanism 3, the wood can be cut into pieces of suitable size, thus shortening the subsequent pulp preparation time. By setting the pushing mechanism 2, the amount of trunks entering the shredding mechanism 3 at a single time can be controlled to avoid the large amount affecting the shredding result and also avoid affecting the uniformity of subsequent unloading.

[0035] like Figure 1-6 As shown, a square plate 207 is vertically fixed to the end of the pushing base plate 205 near the shredding mechanism 3, and a slide groove 208 is mirror-set on both sides of the square plate 207. A connecting rod 209 is slidably connected in the slide groove 208. Short rods are vertically fixed at both ends of the connecting rod 209. The other ends of the two short rods are connected to the connecting rod 2 210. The two short rods on the upper and lower sides are respectively slidably connected to the slide grooves 212 at both ends of the two connecting rods 3 211. The two connecting rods 3 211 are parallel and the middle parts are rotatably connected to the square plate 207. A guide rod 213 is vertically fixed to the side of the connecting rod 2 210 near the breaking mechanism 1, and the other ends of the two guide rods 213 vertically penetrate the two sides of the pushing plate 201. The side of the connecting rod 2 210 near the shredding mechanism 3 is vertically fixed to the two sides of the isolation plate 214, and the isolation plate 214 is located between the pushing base plate 205 and the shredding belt 302 in the shredding mechanism 3.

[0036] By adopting the above technical solution, when the screw rod 202 rotates, the push plate 201 descends, blocking the long strip of tree trunks being crushed in the conveyor belt 101 from entering the push bottom plate 205. When the stacking plate descends, the push plate 201 drives the guide rod 213 to descend. Since the guide rod 213 is fixed to the side of the connecting rod 210, the connecting rod 1 209 close to the crushing mechanism 1 descends. Since the two connecting rods 1 209 are connected by the connecting rod 3 211, at this time, the connecting rod 213 is connected to the connecting rod 210. The third link 211 rotates, and the link 1 209 close to the shredding mechanism 3 rises. At this time, the two links 1 209 and the link 3 211 form a seesaw connection. Since the end of the link 3 211 is provided with a second slide groove 212, and the short rod slides in the slide groove 1 208, and the link 1 209 slides in the second slide groove 212, the link 1 209 and the link 2 210 maintain a vertical state when they are lifted. Therefore, when the guide rod 213 descends, the isolation plate 214 is raised, so that when the push plate 201 moves toward the shredding mechanism 3, the tree trunks at the pushing point can be smoothly pushed onto the shredding belt 302. The isolation plate 214 plays a blocking role after the long tree trunks can all enter the shredding belt 302, avoiding the tree trunks being shredded when they are generally exposed to the outside, which is easy to cause danger; then, when the cylinder 206 drives the sliding plate 204 to approach the shredding mechanism 3, the push plate 201 will now push all the tree trunks that have been on the pushing bottom plate 205 into the shredding belt 302. After the pushing is completed, the screw rod 202 reverses, the push plate 201 rises, the isolation plate 214 drops, and then the push plate 201 retreats. At this time, the tree trunks in the crushing mechanism 1 are transported to the pushing bottom plate 205, and due to the setting of the isolation plate 214, the vertical rod will not be pushed into the shredding mechanism 3. By setting the push plate 201, the tree trunks can be quantitatively transported for shredding, avoiding the generation of more or less wood chips, which affects the preparation of pulp.

[0037] like Figure 1-6 As shown, there are a plurality of cutters 301 which are fixed parallelly and vertically on a push plate 304. A push rod 305 is fixed on the outer side of the push plate 304. The bottom of the push rod 305 is vertically fixed to one end of a connecting rod. The other end of the connecting rod passes through an open groove in a shredding side plate 303 which is parallel to the shredding belt 302. A spring 306 is provided on the outer sleeve of the connecting rod in the open groove. The spring 306 drives the push rod 305 to approach the shredding belt 302. A driving component for driving the connecting rod to slide close to the shredding side plate 303 is provided in the shredding belt 302.

[0038] like Figure 1-6As shown, the driving assembly includes a driving rod 1 307 connected to the connecting rod, and the other end of the driving rod is vertically fixed to the long bottom side of the wedge plate 1 308, the wedge plate 1 308 is a right-angled trapezoid, the hypotenuse of the wedge plate 1 308 cooperates with the wedge plate 2 309, the wedge plate 2 309 is a right-angled trapezoid, and the high side of the wedge plate 2 309 is vertically fixed with a driving rod 2 310, and the other end of the driving rod 2 310 is fixed to the connecting point of the sliding plate 1 204 and, when the sliding plate 1 204 is close to the shredding mechanism 3, the wedge plate 2 309 is close to fit the wedge plate 1 308 and drive the wedge plate 1 308 to approach the shredding side plate 303, the number of the cutters 301 is several, and the cross-section of the cutter 301 away from the push plate 304 is set to be triangular, and the cutter 301 is perpendicular to the running direction of the trunk, so when the trunk moves on the shredding belt 302, the tree can be shredded. The trunk is chopped into wood chips. When the sliding plate 204 is close to the shredding mechanism 3, the pushing plate 201 just pushes the trunk onto the shredding belt 302. At the same time, the hypotenuse of the wedge block 2 is close to the hypotenuse of the wedge block 1, driving the wedge block 1 to approach the shredding side plate 303, that is, the cutter 301 retreats from the shredding belt 302 to the shredding side plate 303. The cutter 301 retreats to facilitate the pushing of the trunk onto the shredding belt 302. Further, when the sliding plate 204 is away from the shredding mechanism 3, the wedge plate 2 309 retreats close to the breaking mechanism 1, and the wedge block 1 drives the cutter 301 to cross the shredding belt 302 to complete the shredding of the trunk. During this period, the isolation plate 214 is in a falling state, which blocks the shredding mechanism 3 from the pushing mechanism 2 to ensure the smooth completion of the crushing of the trunk. The whole process is jointly designed to ensure the quantitative shredding of the trunk.

[0039] like Figure 1-6 As shown, the unloading mechanism 4 includes a unloading hopper 41, the discharging port of the unloading hopper 41 is located above the discharging belt 7, and stirring rods 43 are fixed at intervals at the lower part of the stirring shaft 42 located in the unloading hopper 41. The stirring shaft 42 passes through the supporting horizontal plate 44, and a driven gear 45 is fixed to the upper end of the stirring shaft 42. The driven gear 45 is externally meshed with a driving gear 46 rotatably connected to the supporting horizontal plate 44. The driving gear 46 is coaxially fixedly connected to the output shaft of the stirring motor. The driving gear 46 rotates to drive the driven gear 45 to rotate, and then the stirring shaft 42 rotates to drive the stirring rod 43 to stir the wood chips, homogenize the wood chips, and ensure the stability and uniformity of the discharge amount.

[0040] like Figure 1-6As shown, the rotating shaft at the center of the crushing roller 102 is rotatably connected to the circular slide 104, and the circular slide 104 penetrates and slides in the slide grooves 105 on both sides of the support frame. The two ends of the circumferential surface of the crushing roller 102 are symmetrically concavely provided with annular grooves 106, and the annular grooves 106 are limitedly slidably connected with an arc-shaped slide 107. The top surface of the arc-shaped slide 107 is hinged to the bottom of the connecting vertical rod 108. The top of the connecting vertical rod 108 penetrates the pressure plate. The outer sleeve of the connecting vertical rod 108 between the pressure plate and the arc-shaped slide 107 is provided with a spring 109. The spring 109 is provided on the outer sleeve of the connecting vertical rod 108. 09 drives the breaking roller 102 to approach the conveyor belt 101. Due to the different thicknesses of trees, the breaking roller 102 needs to be lifted to a certain height when being conveyed between the conveyor belt 101 and the breaking roller 102. The arc-shaped slide plate 107 is driven to slide in the annular groove 106, the connecting vertical rod 108 is lifted up, and the spring 109 is compressed. The spring 109 and the breaking roller 102 both act on the tree to crush the tree into a long strip. At the same time, pressure blocks 103 are evenly arranged on the breaking roller 102 and the conveyor belt 101 to promote the effect of crushing the tree.

[0041] like Figure 1-6 As shown, the driven gear 45 has a larger tooth width, and a connecting plate frame 47 is sleeved on the stirring shaft 42 between the stirring rod 43 and the driven gear 45. The stirring shaft 42 passes through the connecting plate frame 47 and is connected to the connecting plate frame 47 for limited rotation. The connecting plate frame 47 is provided with open grooves on opposite sides, and rollers are slidably connected in the open grooves. The center rod at the center of the roller passes through the four slide grooves of the rods on the opposite sides of the U-shaped pull rod 48. The pull rod 48 is sleeved and fixed on the outside of the driving rod 3 49. The driving rod 3 49 is coaxially fixedly connected with the output shaft of the driving motor. The bottom of the stirring shaft 42 is vertically fixed to the discharge circle at the bottom of the lower hopper 41. On the board, the discharging circular plate is rotatably connected to the discharging port of the discharging hopper. When the stirring shaft 42 stirs for a certain period of time, the driving motor is started, the driving rod three 49 rotates, and the U-shaped pull rod 48 rotates clockwise, and the center rod drives the roller to slide in the connecting plate frame 47, the connecting plate frame 47 descends, the discharging circular plate descends, and is separated from the lower hopper 41, and the wood chips fall from the lower hopper 41 to the discharging belt 7. When discharging, the shredder mechanism 3 is shredding the tree trunks. After the wood chips are discharged, the wood chips in the shredder mechanism 3 just fall into the lower hopper 41, forming a stable and continuous discharging.

[0042] like Figure 1-6 As shown, vertical baffles 5 are vertically fixed on opposite sides of the pusher bottom plate 205 , and square holes 6 are provided in the vertical baffles 5 . The design of the square holes 6 facilitates the movement space of the pusher plate 201 and the guide rod 213 .
