Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic goods packaging and transportation equipment, and particularly relates to a paper box conveyor feeding device. BACKGROUND

[0002] In the modern commodity production and logistics industry, automatic packaging production lines play a crucial role. Among them, the paper box opening machine is the key equipment to realize the automatic forming and bottom sealing of the paper box. The working efficiency and stability of the opening machine depend largely on whether the front-end feeding device can continuously, stably and accurately supply single, unfolded paper box blanks.

[0003] In the prior art, some devices use a suction cup grabbing method from top to bottom. In this scheme, as the paper box blanks in the hopper are continuously consumed, the top surface height of the stack continues to decrease, so that the reference height of each grabbing changes. This not only requires the grabbing mechanism to have a complex lifting stroke control system to adapt to the height change, but also increases the instability and failure risk of the equipment. More importantly, when a whole stack of paper box blanks is completely grabbed, the device must be stopped for manual feeding, which will cause the production process to be interrupted, greatly reducing the efficiency of continuous production.

[0004] For example, on a spinning production line with extremely high continuity requirements, especially during the automatic boxing stage of spindles and cheese, such downtime caused by feeding will directly interrupt the packaging process, not only seriously affecting the output of a single link, but also easily interfering with the upstream production rhythm, forming a bottleneck of the entire production line. Therefore, a paper box conveyor feeding device is proposed to solve the above problems. SUMMARY

[0005] The purpose of the present application is to provide a paper box conveyor feeding device, which solves the problem of existing paper box feeding devices that need to be stopped during feeding, resulting in production process interruption, low efficiency, and instability and failure risk caused by changing the grabbing height.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme, A paper box conveyor feeding device, comprising a base and a paper box blank, the top of the base is provided with a pushing and separating mechanism and a linkage lifting mechanism, the inside of the pushing and separating mechanism is provided with an air floatation separating mechanism, and the top end of the base is fixedly connected with a hopper; The pushing and separating mechanism comprises a linear driver installed at the left end of the top of the base, the driving end of the linear driver is fixedly connected with a connecting block, and the left and right sides of the containing groove are both provided with a rounded transition area.

[0007] Preferably, the top of the base is provided with a guide groove, the outer wall of the push plate is slidingly connected to the inner wall of the guide groove, and the top right end of the base is provided with a carton opening machine, and the output end of the carton opening machine is provided with a conveyor belt.

[0008] Preferably, the linkage jacking mechanism comprises a support cover fixedly installed at the top end of the base, two first toothed plates fixedly connected to the inner wall of the top of the support cover, support shafts fixedly installed on the front and back of the connecting block, gears fixedly connected to the support shafts, two top plates fixedly connected to the gears through a transmission assembly, the top side of the two top plates in contact with the bottom side of the carton blank, and reset assemblies provided on the front and back of the top plate.

[0009] Preferably, the transmission assembly comprises two long strips slidingly arranged in the push plate, second toothed plates fixedly connected to the left end of the two long strips, two inclined grooves provided at the top of the long strips, support seats fixedly connected to the front and back of the bottom end of the top plate, and rollers installed in the support seats.

[0010] Preferably, the outer part of the gear is meshingly connected to the outer part of the first toothed plate, and the outer part of the gear is meshingly connected to the outer part of the second toothed plate.

[0011] Preferably, the outer wall of the two top plates is slidingly connected to the inner wall of the push plate, and the outer wall of the roller is slidingly matched with the inner wall of the inclined groove.

[0012] Preferably, the reset assembly comprises limiting rods fixedly connected to the front and back of the top end of the top plate, reset springs sleeved on the outer part of the limiting rods, limiting grooves provided at the four corners of the inside of the push plate, and the front and back of the top plate slidingly in contact with the inner wall of the two limiting grooves.

[0013] Preferably, the bottom side of the two reset springs is in abutment with the top plate, the top side of the reset spring is in abutment with the inner wall of the top of the limiting groove, the rod part of the limiting rod is arranged above the push plate part of the limiting groove, and the bottom side of the end part of the limiting rod is in contact with the top side of the push plate.

[0014] Preferably, the air floatation separation mechanism comprises an air cavity provided in the inside of the containing groove and below the left circular corner transition area, a plurality of air injection ports provided at the top of the containing groove and in communication with the air cavity, air inlets provided on the front and back of the push plate and in communication with the air cavity, and an air source interface installed on the outside of the air inlet.

[0015] Preferably, the carton blank is placed in the stock bin, the carton blank is in contact with the containing groove, and the plurality of air injection ports are arranged along the length direction of the circular corner transition area.

[0016] The application provides a carton conveyor feeding device. The following advantages are achieved: 1. In the application, the push plate is driven by a linear drive to perform horizontal reciprocating motion, and the stability and trajectory accuracy of the pushing process are ensured by the guide groove on the base, effectively preventing yawing. The accommodating groove on the top of the push plate cooperates with the discharge port of the hopper to accurately support the bottommost carton blank, and the design of the hopper can replenish carton blanks at any time, realizing continuous feeding without stopping during production and improving the overall operation efficiency of the equipment. The design of the fillet transition area on both sides can significantly reduce the friction and jamming of the carton edge during pushing, ensuring that the carton blanks can be smoothly and accurately separated one by one and pushed to the predetermined station, laying a reliable foundation for subsequent carton opening operations.

[0017] 2. In the application, compressed air is obtained through the air source interface, enters the air cavity inside the accommodating groove and below the left fillet transition area through the air inlet, and then high-pressure air flow is sprayed through multiple air outlets arranged along the length direction of the fillet transition area, forming a uniform supporting air film between the bottommost carton blank and the upper carton blank. The air film can significantly reduce the friction between the two carton blanks, effectively eliminate the adhesion phenomenon caused by static electricity, moisture or material characteristics, and actively prevent the second-to-last carton blank from following, thereby ensuring the accurate single separation of the carton blanks and avoiding the common problem of multiple feeding, while avoiding physical damage to the carton blanks, ensuring product quality and production efficiency.

[0018] 3. In the application, the pushing and separating mechanism does not require an additional independent power source. When the push plate moves to the right, the gear on the connecting block accurately converts the horizontal motion into the relative motion of the long strip plate through the meshing of the first tooth plate and the second tooth plate on the long strip plate in the transmission assembly. The inclined slot on the top of the long strip plate interacts with the roller on the bottom of the top plate to convert the horizontal force into vertical lift, driving the top plate to rise smoothly. This mechanical linkage does not require an additional lifting drive source, reducing the complexity of the control system and lowering the failure rate and maintenance cost.

[0019] 4. In the application, after the carton blank is lifted to the predetermined height, it can be immediately grabbed by the carton opener installed on the base and sent to the conveyor belt for subsequent processing, realizing seamless connection. Then the linear drive moves in reverse, quickly driving the push plate and the connecting block back to the starting position, and the reset spring on the top plate can quickly and smoothly bring the top plate back to the initial position after the lifting driving force is removed, ensuring that the device can operate continuously and efficiently, thereby significantly improving the overall capacity of the automated production line.

[0026] With reference to Figure 2 , Figure 4 and Figure 6 , the air floatation separation mechanism 4 comprises an air cavity 41 arranged in the inside of the accommodating groove 24 and below the left side round corner transition area 25, the top of the accommodating groove 24 is provided with a plurality of air injection ports 42, which are in communication with the air cavity 41, the plurality of air injection ports 42 are arranged along the length direction of the round corner transition area 25, which can accurately inject air flow to the bottom of the carton blank 6, these injected air flows form a layer of uniform air cushion between the carton blanks 6, effectively reducing the friction and eliminating static adsorption; the front and rear sides of the push plate 23 are provided with air inlets 43, which are in communication with the air cavity 41, the outside of the air inlet 43 is provided with an air source interface 44, the air source interface 44 receives external compressed air, and the air is guided into the air cavity 41 through the air inlet 43 arranged in the inside of the push plate 23, the air cavity 41 serves as a buffer space for air storage and distribution, and finally the air is injected out through the air injection port 42, so as to ensure that the bottommost carton blank 6 can be smoothly and damagelessly separated and pushed; Specifically, external compressed air is received through the air source interface 44 and guided into the air cavity 41 through the air inlet channel 43 inside the push plate 23, and the air cavity 41 uniformly distributes the gas to the plurality of air injection ports 42 at the top of the containing groove 24 and precisely sprays the air flow along the fillet transition area 25, forming a uniform supporting air film between the bottommost carton blank 6 and the carton blank 6 above, which can significantly reduce the friction between the two carton blanks 6, completely eliminate the sticking problem caused by static electricity, moisture or rough surface, and fundamentally eliminate the occurrence of multiple feeding. This non-contact separation method avoids physical damage to the carton blank 6 and significantly improves the success rate and reliability of separation; preferably, when the push plate 23 is reset, the external air source connected with the air source interface 44 is switched from blowing to suction, and negative pressure is generated in the containing groove 24 through the same air injection port 42, thereby actively assisting the bottommost carton blank 6 in the hopper 5 to fall and accurately position, ensuring the reliability of the next feeding cycle.

[0027] Working principle: First, a large number of carton blanks 6 are stacked in the hopper 5, and in the initial state of the device, the push plate 23 in the push and separation mechanism 2 is located directly below the hopper 5, and the containing groove 24 at the top of the push plate 23 is aligned with the discharge port of the hopper 5, so that the bottommost carton blank 6 can fall into or contact the containing groove 24, when the device receives a feeding instruction, the linear driver 21 starts to work to drive the connecting block 22 to drive the right push plate 23 to move horizontally to the right, in the initial stage of the right movement of the push plate 23, the air floatation separation mechanism 4 inside the push and separation mechanism 2 is started synchronously, compressed gas is obtained from the external air source interface 44 through the air inlet channel 43 installed on the front and rear sides of the push plate 23, the gas enters the air cavity 41 below the left fillet transition area 25 through the air inlet channel 43, and then the high-pressure gas is sprayed from the air injection port 42, forming a supporting air film between the carton blank 6 in the containing groove 24 and the second-to-last carton blank 6 in the hopper 5, effectively reducing the friction between the two layers of carton blanks 6, eliminating static cling, and preventing the second-to-last carton blank 6 from moving with the bottommost carton blank 6, thereby ensuring the accurate separation of a single carton blank 6, and the push plate 23 slides in the guide groove 26, ensuring the stability and accuracy of the pushing movement; With the continuous movement of the connecting block 22 and the push plate 23 to the right, the linkage lifting mechanism 3 is triggered. When the push plate 23 moves to the right, the gear 34 meshes with the outside of the first toothed plate 32 to drive, and the second toothed plate 35 also meshes with the outside of the gear 34 to connect, so that the gear 34 drives the second toothed plate 35 and the long strip plate 36 to move while meshing with the first toothed plate 32. When the long strip plate 36 moves to the right under the drive of the gear 34, the inclined surface structure of the inclined slot 37 will push the roller 310 upward, thereby driving the top plate 38 to move upward. The top plate 38 contacts the bottom side of the carton blank 6 in the containing groove 24, and lifts the carton blank 6 upward to a predetermined height, so that the subsequent box opening machine 7 can grasp and further process it. When the top plate 38 is lifted to the maximum height or completes the lifting, the reset components arranged on the front and back sides of the top plate 38 begin to play a role. When the top plate 38 is pushed by the force from the mechanism below, the reset spring 312 is compressed. When the pushing force is removed or lowered, the reset spring 312 can help the top plate 38 to reset stably. The lifted carton blank 6 waits for the box opening machine 7 to grasp and further process it. The conveying belt 8 arranged at the output end of the box opening machine 7 conveys the opened carton to the next process. Then the linear driver 21 moves reversely, driving the push plate 23 and the connecting block 22 to return to the initial position. The linkage lifting mechanism 3 is lowered under the action of the reset component, and the top plate 38 returns to the initial position. The whole device is ready for the next feeding cycle of the carton blank 6. During the left reset of the push plate 23, the air floatation separation mechanism 4 is started again. However, the air source supply device connected outside the air source interface 44 is switched from blowing to suction at this time. With the gradual displacement of the containing groove 24 directly below the hopper 5, suction generates negative pressure in the containing groove 24, which can actively and reliably assist the carton blank 6 at the bottom of the hopper 5 to fall and be accurately positioned in the containing groove 24, preparing for the next working cycle.

[0028] Example two, based on example one, the embodiment further discloses the following contents: As Figures 7-8As shown, a pre-separation mechanism is arranged at the right side of the discharge end of the hopper 5, which includes a support shaft 51 arranged at the right side of the discharge end of the hopper 5, a connecting rod 52 fixedly connected to the right side of the support shaft 51, and a separation paddle 54 fixedly connected to the left side of the support shaft 51. The connecting rod 52 and the separation paddle 54 are in V shape. A push plate 53 is arranged at the top end of the push plate 23 and close to the right side of the accommodating groove 24. When the push plate 53 returns, it is in contact with the bottom side outer wall of the connecting rod 52 and extrudes it to rotate counterclockwise around the support shaft 51, thereby driving the separation paddle 54 to swing downward. The tip of the separation paddle 54 touches and presses the edge of the bottom layer (i.e., the last but one) carton blank 6 that is about to fall into the accommodating groove 24, which makes the bottom layer carton blank 6 produce a slight elastic deformation or vibration, thereby actively destroying the electrostatic adsorption or surface tension between the bottom layer carton blank 6 and the last but one carton blank 6 above. This non-invasive pre-separation method creates conditions for the airflow penetration of the subsequent air floatation separation mechanism 4, significantly improves the reliability of separation, and allows the air pressure required for air floatation separation to be appropriately reduced, achieving the effect of energy saving. A torsional spring 55 is arranged outside the support shaft 51. When the push plate 23 starts the next round of pushing, the push plate 53 is out of contact with the connecting rod 52. Under the restoring force of the torsional spring 55, the separation paddle 54 and the connecting rod 52 automatically rotate clockwise and reset, waiting for the next trigger.
