Description

Technical Field

[0001] This invention relates to the field of paperboard processing technology, and more specifically to a material conveying device for conveying paper box processing boards. Background Technology

[0002] In the process of paper box production and processing, stacked paper box processing boards need to be transported one by one to the subsequent processing station. At present, most paper box processing board feeding equipment on the market uses conveyor belts with simple pushing structures to achieve feeding, but it has obvious defects in actual application.

[0003] For example, stacked cardboard processing boards are prone to sticking together due to factors such as pressure and adsorption, which makes it impossible to accurately separate individual cardboard sheets during material feeding. As a result, multiple cardboard sheets are often pushed at the same time, which not only affects the normal progress of subsequent processing steps, but may also cause cardboard waste and equipment failure, seriously restricting the automation level and production efficiency of cardboard box production.

[0004] Therefore, developing a paperboard feeding device that can effectively solve the problem of cardboard adhesion and achieve precise feeding of single sheets has become an urgent technical problem to be solved in the current paperboard production field. Summary of the Invention

[0005] This invention provides a feeding device for conveying cardboard processing boards to solve the problem that the adhesion between stacked cardboard cannot be effectively separated, which leads to multiple cardboard sheets being pushed at the same time or the cardboard being bent during the feeding process, reducing the feeding effect and subsequent processing efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0058] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0059] like Figures 1 to 10 As shown, an embodiment of the present invention provides a conveying device for conveying cardboard processing boards, including a support plate 1, a conveyor belt 9, and a stacking frame 11 disposed on the support plate 1. Multiple cardboard sheets 13 are stacked inside the stacking frame 11. Slide plates 14 are symmetrically arranged on the inner side of the support plate 1 to support the movement and conveying of the cardboard sheets 13. A rotating roller 3 is rotatably disposed inside the support plate 1. A belt 6 is symmetrically arranged on the outer side of the rotating roller 3 and located below the slide plate 14. Two L-plates 7 are disposed on the belt 6, and rubber balls 8 are disposed on the end faces of the L-plates 7 to separate the cardboard sheets 13 from the bottom of the stacking frame 11 as the belt 6 rotates. The device also includes:

[0060] The stacking frame 11 has an inclined angle, and the cardboard 13 is stacked in a stepped manner inside the stacking frame 11 and supported on the slide plate 14;

[0061] The shovel section is symmetrically arranged on both sides of the stack frame 11. It includes a connecting pusher symmetrically arranged above the rotating roller 3 and extends to the moving path of the L plate 7. It passes through the symmetrically arranged and movable connecting shovels on both sides of the stack frame 11 so as to be pushed by the L plate 7 to shovel and separate the cardboard 13 at the bottom of the stack.

[0062] The follower is located on both sides of the stack and connected to the shovel section. It includes a switch 35 located at the end of the connecting pusher and an electric rod 32 electrically connected to the switch 35, so that the connecting shovels on both sides of the stack frame 11 can be moved synchronously by the L plate 7.

[0063] The air-assisted part, which is installed through the connecting shovel, includes a pneumatic component consisting of an airbag 27 and an air pipe 29 symmetrically arranged below the stack frame 11, and an air spray component installed through the connecting shovel to spray gas to assist in separating the adhesive cardboard 13.

[0064] Specifically, there are two rollers 3. Support legs 2 are symmetrically fixed below the support plate 1. A motor 4 is fixed on the outside of the support plate 1, and the driving end of the motor 4 is connected to one of the rollers 3. Pulleys 5 are symmetrically arranged on the outside of the rollers 3. The belt 6 is sleeved on the outside of the pulleys 5. A motor 10 is fixed on the outside of the support plate 1, and the driving end of the motor 10 is connected to the conveyor belt 9 to drive the conveyor belt 9 to rotate.

[0065] The support leg 2 provides stable support for the support plate 1 and provides a through channel for the fixed components. The support plate 1 provides rotational support for the roller 3. The roller 3 provides support for the pulley 5. The support plate 1 also provides stable support for the motor 4. The motor 4 can drive the roller 3 to rotate using the drive end. The pulley 5 provides support for the belt 6. The roller 3 can use rotational power to drive the belt 6 to rotate through the pulley 5. The belt 6 provides stable support for the L plate 7, so that the L plate 7 can push the cardboard 13 at the bottom of the stack to move upwards on the conveyor belt 9 under the drive of the belt 6. The support plate 1 provides rotational support for the conveyor belt 9. The conveyor belt 9 can transport the ejected cardboard 13 for processing.

[0066] The stack frame 11 gradually tilts away from the conveyor belt 9 from bottom to top;

[0067] Multiple baffles 12 are evenly fixed on the inner side of the stacking frame 11 to reduce the friction between the stacking frame 11 and the cardboard 13 and to position the cardboard 13.

[0068] Specifically, the stacking frame 11 provides space for the cardboard 13 to be stacked and moved through, and provides stable support for the baffle 12. The baffle 12 can cooperate with the stacking frame 11 to provide a limiting function for the cardboard 13, and can reduce the contact area between the stacking frame 11 and the cardboard 13, thereby reducing friction, so that the cardboard 13 can move along the baffle 12 towards the slide plate 14 under the action of gravity. The slide plate 14 can provide moving support for the cardboard 13.

[0069] In practical application, workers can use fixed components to fix the support leg 2 at the work site, so that the support leg 2 can stably support the support plate 1. Then, workers can stack the cardboard 13 for cardboard box processing in the stacking frame 11 according to the actual needs. At the same time, under the support of the sliding plate 14, the baffle 12 and the stacking frame 11 are tilted at an angle to limit the stacked cardboard 13, so that the cardboard 13 forms a stepped shape that is inclined away from the conveyor belt 9. The multiple cardboard 13 forming a stepped shape can make the cardboard 13 intersect each other, reduce edge pressure, and make it easier for the shovel plate 19 to be inserted between two cardboard 13. Then, the workers need to start the motor 4 and the motor 10, so that the motor 4 drives the rotating roller 3 to rotate under the support plate 1. The power drives the pulley 5 to rotate, which in turn transmits the rotational power to the belt 6. This allows the belt 6 to rotate synchronously with the two rollers 3 via the pulley 5, thus enabling the belt 6 to rotate. During this rotation, the belt 6 also drives the L-plate 7 to move along the path of the belt 6. The L-plate 7 can then move the rubber ball 8 along with the L-plate, bringing the rubber ball 8 into contact with the bottom cardboard 13. The rubber ball 8 can then use the external force and friction between itself and the cardboard 13 to push the cardboard 13 along the slide plate 14 towards the conveyor belt 9. This allows the bottom cardboard 13 in the stack frame 11 to move above the conveyor belt 9, so that the conveyor belt 9, driven by the motor 10, can use friction to transport the cardboard 13, facilitating the processing of the cardboard 13.

[0070] As a preferred embodiment of the present invention, the connecting pusher includes:

[0071] Guide components are located on one side of the stack frame 11;

[0072] The grooves 15 are symmetrically opened on both sides of the stack frame 11 and extend through the lower end of the stack frame 11;

[0073] There are four supports 20, and two supports 20 form a group. A group of supports 20 is symmetrically arranged above the rotating roller 3, and one end extends vertically upward.

[0074] Specifically, the stack frame 11 can provide opening space for the groove 15, and the groove 15 can provide moving space for the support 20, the connecting shovel plate and the airbag 27.

[0075] Guide components include:

[0076] Guide rails 16 are symmetrically fixed on both sides of the stack frame 11;

[0077] Track 31 is continuously formed below guide rail 16 and on the inner top wall of groove 15;

[0078] T-bar 17 is located below guide rail 16 and cooperates with track 31.

[0079] Specifically, the stack frame 11 can provide stable support for the guide rail 16, the guide rail 16 can provide opening space for the track 31, the track 31 has a T-shaped structure, which can provide a through channel and movement guide for the T rod 17, and together with the guide rail 16 can provide support for the T rod 17, so that the T rod 17 can provide support for the N plate 18.

[0080] The connecting shovel includes:

[0081] N plate 18, there are two, symmetrically arranged between L plate 7 and groove 15, and connected to the lower end of T rod 17;

[0082] The two sets of brackets 20 are respectively connected to the two N plates 18;

[0083] There are four shovel-separating plates 19, with two shovel-separating plates 19 forming a group. Each group of shovel-separating plates 19 is connected to the N plate 18, and one end is an inclined surface to separate the cardboard 13 stacked at the bottom.

[0084] Specifically, the T-bar 17 can provide stable support for the N-plate 18, so that the N-plate 18 can provide support for the bracket 20, and the N-plate 18 can provide stable support for the splitting plate 19, one end of which is sharp.

[0085] In practical application, when belt 6 drives L plate 7 to rotate clockwise, L plate 7 will first contact push plate 23 during the movement, and push plate 23 will push turntable 22. Under the action of external force, turntable 22 will push support 20 through first spring 21. Under the action of external force, support 20 can push N plate 18 away from conveyor belt 9 towards the stacked cardboard 13. At the same time, N plate 18 will drive shovel plate 19 to move together. The sharp end of shovel plate 19 will use external force and the stepped shape formed by stacked cardboard 13 to insert between the bottom cardboard 13 and the second cardboard 13 from the bottom. Under the action of external force, the cardboard 13 at this position can be gradually separated by the inclined surface of shovel plate 19. This makes it easier for L plate 7 and rubber ball 8 to push out the bottom cardboard 13, preventing cardboard 13 from sticking or being absorbed and affecting the push-out conveying.

[0086] In a preferred embodiment of the present invention, the follower includes:

[0087] The first spring 21 is sleeved on the outside of the vertically upward extending bracket 20;

[0088] Turntable 22 is rotatably mounted on the upper end of bracket 20 and connected to the first spring 21;

[0089] Push plate 23 is fixed on turntable 22, and one end is connected to switch 35;

[0090] The actuator is located on the guide rail 16, which is away from the bracket 20, and is connected to the T-bar 17, which is also away from the bracket 20.

[0091] Specifically, the bracket 20 can provide support for the lower end of the first spring 21, the first spring 21 can use its elasticity to position the turntable 22, and the bracket 20 can provide rotational support for the turntable 22. The turntable 22 can provide support for the push plate 23, and the push plate 23 can stably support the switch 35. When the switch 35 is pressed and triggered, it will control the electric rod 32 to retract. When the pressure on the switch 35 disappears, it will rebound and reset, at which time it will control the electric rod 32 to extend.

[0092] The actuating parts include:

[0093] The electric rod 32 is fixed above the guide rail 16, which is away from the bracket 20;

[0094] Fixed plate 33 is fixed to the telescopic end of electric pole 32;

[0095] The connecting plate 34 is fixed at one end to the lower end of the fixed plate 33, and the other end is connected to the T rod 17 away from the bracket 20.

[0096] Specifically, the guide rail 16, which is away from the bracket 20, can provide stable support for the electric rod 32. The electric rod 32 can provide support for the fixed plate 33. The fixed plate 33 can stably support the connecting plate 34, so that the connecting plate 34 can provide support for the T rod 17, which is away from the bracket 20. The T rod 17 can provide support for the N plate 18, which is away from the bracket 20, and can cooperate with the guide rail 16, which is away from the bracket 20, to provide movement guidance for the N plate 18. The electric rod 32 should be in the extended state of the telescopic end in its initial state.

[0097] In practical application, when belt 6 drives L plate 7 to rotate clockwise, L plate 7 will press switch 35 while pushing push plate 23. Switch 35 is triggered by one end of L plate 7 under the support of push plate 23, thereby controlling electric rod 32 to retract. Electric rod 32, supported by guide rail 16 away from support 20, uses telescopic end to drive fixed plate 33 to move closer to stack frame 11. Fixed plate 33 can then push T rod 17 away from support 20 along track 31 closer to cardboard 13 via connecting plate 34. T rod 17 can then use external force to push N plate 18 away from support 20 to move together. N plate 18 can then push shovel plate 19 away from support 20 to move closer to cardboard 13. Thus, both sets of shovel plates 19 can move together closer to cardboard 13 and shovel the bottom cardboard 13, improving the separation effect of cardboard 13.

[0098] In a preferred embodiment of the present invention, the pneumatic component includes:

[0099] The airbag 27 is movably disposed inside the N plate 18, with one end connected to the inner wall of the N plate 18 and the other end in contact with one of the baffles 12.

[0100] A one-way valve 28 is provided through one end of the airbag 27;

[0101] One end of the trachea 29 is connected to the air bag 27, and the other end passes through the shovel plate 19 and communicates with the inner cavity 24;

[0102] The second spring 30 is symmetrically arranged inside the airbag 27, with one end connected to one end of the airbag 27 and the other end connected to the other end of the airbag 27.

[0103] Specifically, the airbag 27 can provide support for the one-way valve 28 and the second spring 30 under the support of the N plate 18. The one-way valve 28 is a valve type, which can only provide a channel for outside air to enter the airbag 27. The elasticity of the second spring 30 is lower than that of the first spring 21 (when the first spring 21 and the second spring 30 are pushed by the same external force, the second spring 30 will deform and contract, while the first spring 21 will not deform). The air tube 29 can provide a channel for the air in the airbag 27 to enter the inner cavity 24. The baffle 12 can provide a blocking effect for one end of the airbag 27.

[0104] The air jet components include:

[0105] The inner cavity 24 is located inside the shovel plate 19;

[0106] The opening 25 is located on the inclined surface of the shovel plate 19;

[0107] Multiple air nozzles 26 are evenly arranged in the opening 25 and communicate with the inner cavity 24.

[0108] Specifically, the shovel plate 19 provides space for the inner ring and the opening 25, the opening 25 provides space for the air nozzle 26 to be installed, preventing the air nozzle 26 from interfering with the insertion of the shovel plate 19 between the two cardboard pieces 13, the inner cavity 24 provides a channel for air to enter the multiple air nozzles 26, and the air nozzles 26 can spray gas under air pressure.

[0109] In practical application, when L-plate 7 pushes N-plate 18 towards cardboard 13 via push plate 23, turntable 22, first spring 21, bracket 20, and electric rod 32 through fixed plate 33 and connecting plate 34, N-plate 18 moves airbag 27 together, allowing airbag 27 to contact baffle 12. As N-plate 18 continues to move, airbag 27, under the pressure of N-plate 18 and the resistance of baffle 12, pushes second spring 30 to deform and contract, simultaneously compressing and contracting airbag 27. During this process, air inside airbag 27 is squeezed into air tube 29, passes through air tube 29 into inner cavity 24, and then passes through... The inner cavity 24 enters the air nozzle 26, and finally, under the action of air pressure, the gas passes through the air nozzle 26 and the opening 25 and is sprayed out to the seam between the bottom cardboard 13 and the cardboard 13 above it. This allows the sprayed gas to blow open the edges of the two cardboards 13, making it easier for the separating plate 19 to be inserted between the two cardboards 13. This prevents the cardboard 13 from bending due to the separating plate 19 being unable to be inserted between the two cardboards 13, and makes the insertion of the separating plate 19 between the two cardboards 13 more effective. After the separating plate 19 is inserted between the two cardboards 13, the gas further blows open the two cardboards 13 that are adsorbed together, improving the separation effect of the cardboard 13.

[0110] When the second spring 30 and the airbag 27 contract to their limit, as the L-plate 7 continues to move, and with the cardboard 13 resisting the airbag 27, more external force (the force of the L-plate 7 moving towards the conveyor belt 9) is applied to the first spring 21 through the push plate 23 and the turntable 22. This causes the first spring 21 to deform, allowing the turntable 22 and the push plate 23 to rotate clockwise under the support of the upper end of the bracket 20. At the same time, the push plate 23 will drive the switch 35 to rotate as well, allowing the switch 35 to rotate 90 degrees and then bypass the L-plate 7, separating the L-plate 7 from the switch 35 and the push plate 23, allowing the L-plate 7 to continue its rotational movement. Afterward, the first spring 21 will use its rebound force to drive the turntable 22 and the push plate 23 to rotate in the opposite direction and reset. At the same time, the push plate 23 will drive the switch 35 to rotate and reset, ready for use in the next cycle. Meanwhile, the second spring 30... The external force disappears as L-plate 7 separates from push plate 23. Then, the airbag 27 rebounds and resets under the resistance of stop bar 12. At the same time, under the rebound force of second spring 30, airbag 27 moves N-plate 18 away from stop bar 12. N-plate 18 can move T-rod 17 and bracket 20 along track 31 to reset. After L-plate 7 separates from switch 35, switch 35 rebounds, thereby controlling electric rod 32 to extend. Electric rod 32 can push fixed plate 33 and connecting plate 34 with telescopic end. Connecting plate 34 can move N-plate 18 away from bracket 20 away from cardboard 13 to reset. At the same time, N-plate 18 moves airbag 27 away from bracket 20 to reset. Thus, the two N-plates 18 can synchronously move shovel plate 19 to reset and prepare for the next cycle of work.

[0111] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
