Description

Technical Field

[0001] This invention relates to the field of packaging material equalization control technology, specifically to a material equalization control mechanism and a packaging machine having the mechanism. Background Technology

[0002] Blueberries, as a new small berry species with high economic value and broad development prospects, have delicate flesh, tiny seeds, a sweet and sour taste, a refreshing and pleasant aroma, and are rich in various vitamins and trace elements. Fresh blueberries can be eaten raw or used as raw materials for processing into juice, wine, jam, etc., and have high economic value. After processing, blueberries need to be packaged using packaging machines.

[0003] In the prior art, a fully automatic blueberry packaging machine with publication number "CN116788579A" includes a conveying mechanism. A double-headed cylinder and a clamping plate work together to clamp and fix the blueberry frames. Then, a motor and a drive roller work together to rotate a synchronous pulley, which in turn drives a synchronous belt. This synchronous belt lifts the blueberry frames. The cylinder and a toothed plate work together, and the toothed plate and a gear work together to rotate a shaft, which in turn rotates the blueberry frames, facilitating the pouring of blueberries into the hopper and thus improving the conveying process. This not only saves time but also reduces the workload of workers. Furthermore, the machine utilizes a discharge port and a spring. During the descent, the inertia of the blueberries stretches the spring, causing the discharge port to descend further, reducing the distance the blueberries fall and preventing collisions.

[0004] However, existing technologies still have significant drawbacks. For example, during the blueberry transport process, a single belt is typically used to feed blueberries into multiple conveyor channels simultaneously. However, the quantity distribution of blueberries during transport is difficult to control, and uneven material distribution across the belt can lead to problems such as some conveyor channels being clogged due to excessive material feeding and others being clogged due to insufficient material feeding, thus reducing work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a material equalization control mechanism and a packaging machine having the mechanism, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0011] The diversion assembly includes a herringbone diversion plate located above the first conveyor belt and a lifting rod that drives the herringbone diversion plate to slide up and down. The distance between the two sides of the herringbone diversion plate located behind the swing assembly increases in the direction away from the swing assembly.

[0019] Preferably, the adjacent baffle panels are hinged together, and an electromagnet that repels the electromagnet on the adjacent baffle panel is installed on the baffle panel. An elastic pull block that pulls the adjacent baffle panels closer together is fixedly connected between them. The two baffle panels at both ends are respectively fixedly connected to a first fixed rod and a second fixed rod. The swing housing is fixedly connected to a limiting plate near the first fixed rod.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-10 The present invention provides a technical solution:

[0036] A material equalization control mechanism, comprising:

[0037] Conveyor 1 includes a first conveyor belt 11 that conveys materials under the drive of a motor. The motor drives the first conveyor belt 11 to move in the following manner: drive rollers are slidably installed at both ends of the first conveyor belt 11. The motor drives the drive rollers to rotate, thereby causing the drive rollers to drive the first conveyor belt 11 to move. In this way, the first conveyor belt 11 transports the materials located above it from front to back. Multiple conveying channels are provided at the rear end of the first conveyor belt 11, and the materials at each end of the first conveyor belt 11 are respectively put into different conveying channels.

[0038] Furthermore, the conveyor 1 also includes a conveyor housing 12 wrapped around the left and right sides of the first conveyor belt 11, and two first limiting strips 16 installed parallel to the first conveyor belt 11. The two first limiting strips 16 are located on the left and right sides of the first conveyor belt 11, so that the first limiting strips 16 can block and limit the material on the first conveyor belt 11, and prevent the material from spilling from the first conveyor belt 11.

[0039] Furthermore, the conveyor housing 12 is fixedly connected to a second mounting rod 14 extending above the first conveyor belt 11. The second mounting rod 14 is located above the rear end of the first conveyor belt 11, and a monitoring camera 15 with its camera end pointing downwards is installed on the second mounting rod 14. The monitoring camera 15 monitors the material quantity distribution at various points on the first conveyor belt 11, making it easy to detect any abnormalities in the material distribution on the first conveyor belt 11 in a timely manner. When an abnormality is detected in the material distribution on the first conveyor belt 11, the working states of the swing assembly 2, the curtain assembly 3, and the diversion assembly 4 are adjusted to restore the material distribution on the first conveyor belt 11 to a uniform distribution state, thereby avoiding the problems of material blockage or insufficient material in multiple conveying channels.

[0040] The swaying assembly 2 includes a second conveyor belt 21 located above the front end of the first conveyor belt 11 and conveying materials under the drive of a variable speed motor, and a push-pull electric cylinder 23 that drives the second conveyor belt 21 to slide left and right on the first conveyor belt 11. The variable speed motor drives the second conveyor belt 21 to move in the following manner: drive rollers are slidably installed at both ends of the second conveyor belt 21, and the variable speed motor drives the drive rollers to rotate, thereby causing the drive rollers to drive the second conveyor belt 21 to move. This allows the second conveyor belt 21 to transport the materials above it from front to back. After the second conveyor belt 21 passes the rear end of the second conveyor belt 21, the materials fall onto the first conveyor belt. At the front end of 11, the first conveyor belt 11 continues to convey materials. When there is less material at a certain point on the first conveyor belt 11, the second conveyor belt 21 is pulled left and right by the push-pull electric cylinder 23, so that the second conveyor belt 21 is aligned with the point on the first conveyor belt 11 where there is less material. This enhances the material input at the point on the first conveyor belt 11 where there is less material, and achieves the effect of uniform material distribution. At the same time, the conveying speed of the second conveyor belt 11 can be adjusted by the variable speed motor, and the dwell time of the second conveyor belt 11 at a certain position can be adjusted by the push-pull electric cylinder 23, so as to adjust the material distribution entering the first conveyor belt 11, thereby making the material evenly distributed at all points on the first conveyor belt 11.

[0041] Furthermore, the swaying assembly also includes a swaying housing 22 wrapped around the outside of the second conveyor belt 21, two second limiting strips 24 parallelly mounted on the second conveyor belt 21, and a support block 25 fixedly disposed below the end of the second conveyor belt 21 away from the conveyor 1. The output end of the push-pull electric cylinder 23 is fixedly mounted on the swaying housing 22, so that the output end of the push-pull electric cylinder 23 drives the second conveyor belt 21 to slide left and right through the swaying housing 22. The two second limiting strips 24 are respectively located on the left and right sides of the second conveyor belt 21, so that the second limiting strips 24 block and limit the material on the second conveyor belt 21, preventing the material from spilling off the second conveyor belt 21. The support block 25 provides support and stability to the front end of the second conveyor belt 21, preventing the end of the second conveyor belt 21 extending out of the first conveyor belt 11 from tilting downward and falling.

[0042] The baffle assembly 3 includes several baffle panels 31 positioned above the second conveyor belt 21 and movably arranged relative to each other. These baffle panels 31 are spaced apart horizontally above the second conveyor belt 21 and can slide left and right. When there is less material in the area of ​​the first conveyor belt 11 aligned with the second conveyor belt 21, the baffle panels 31 are pulled closer together to reduce their area on the second conveyor belt 21. This reduces the obstruction effect of the baffle panels 31 on the material on the second conveyor belt 21, allowing more material to flow smoothly from the second conveyor belt 21 to the first conveyor belt 11. At point 11, the material input is increased in areas where there is less material on the first conveyor belt 11. Similarly, when there is more material in areas of the first conveyor belt 11 aligned with the second conveyor belt 21, multiple baffles 31 are pulled apart to move away from each other. While ensuring that the distance between adjacent baffles 31 is insufficient for material to pass through, the area occupied by the baffles 31 on the second conveyor belt 21 is increased. This allows the baffles 31 to block more material on the second conveyor belt 21, thereby avoiding the problem of blockage caused by continuing to send a large amount of material to areas where there is more material on the first conveyor belt 21.

[0043] In one embodiment, the curtain assembly 3 further includes a curtain mounting rod 32 arranged horizontally above the second conveyor belt 21, a fixing plate 33 fixedly connected to the swing housing 22 and fixing the curtain mounting rod 32, and a mounting rod connecting plate 34 fixedly installed at one end of the curtain mounting rod 32. The curtain mounting rod 32 is fixed to the fixing plate 33 by the fixing plate 33, which facilitates the subsequent installation of the curtain 31. The mounting rod connecting plate 34 is designed to facilitate gripping for installing the curtain mounting rod 32. On the mounting rod connecting plate 34, multiple curtain slats 31 are slidably mounted on the curtain slat mounting rod 32, that is, multiple curtain slats 31 slide left and right on the curtain slat mounting rod 32. Specifically, the curtain slat mounting rod 32 has through holes for the curtain slats 31 to slide through, and the inner wall of the through hole and the outer wall of the curtain slat 31 are in frictional contact, so that the curtain slats 31 can remain stable under the action of friction after sliding to the predetermined position. By pushing and pulling multiple curtain slats 31 to slide on the curtain slat mounting rod 32, the multiple curtain slats 31 can move closer to each other or further away from each other.

[0044] In another embodiment, the curtain panels 31 are hinged together. Specifically, one end of an adjacent curtain panel 31 is fixedly connected to a hinge shaft 313, and the other end of an adjacent curtain panel 31 is fixedly connected to several rotating outer sleeves 314 that are rotatably sleeved on the outside of the hinge shaft 313. This allows the two adjacent curtain panels 31 to be hinged together. The hinge shaft 313 is fixedly connected to two shaft connecting blocks 315 that clamp the outer sleeves 314. The shaft connecting blocks 315 block the outer sleeves 314, preventing them from detaching from the hinge shaft 313. Each curtain panel 31 is equipped with an electromagnet 35 that repels an electromagnet 35 on an adjacent curtain panel 31. Adjacent curtain panels 31 are fixedly connected to each other with elastic pull blocks 36 that pull them closer together. (This is necessary when the second conveyor belt needs to be enlarged.) When the amount of material conveyed by the second conveyor belt 21 to the first conveyor belt 11 is reached, the electromagnet 35 is turned off, causing adjacent baffles 31 to move closer to each other under the pull of the elastic block 36, thereby reducing the area occupied by the baffles 31 on the second conveyor belt 21, so that more material can reach the first conveyor belt 11 from the second conveyor belt 21. When it is necessary to reduce the amount of material conveyed by the second conveyor belt 21 to the first conveyor belt 11, the electromagnet 35 is turned on, causing adjacent baffles 31 to move away from each other under the magnetic repulsion of the electromagnet 35, thereby increasing the area occupied by the baffles 31 on the second conveyor belt 21, so that less material can reach the first conveyor belt 11 from the second conveyor belt 21. The magnetic strength of the electromagnet 35 is adjustable, so that multiple baffles 31 can block part of the second conveyor belt 21 or completely block the second conveyor belt 21.

[0045] Furthermore, the two curtain panels 31 located at both ends are respectively fixedly connected to a first fixing rod 38 and a second fixing rod 39. The swing housing 22 is fixedly connected to a limiting plate 37 near the first fixing rod 38. The first fixing rod 38 is fixedly connected to the limiting plate 37, and the second fixing rod 39 is fixedly connected to a limiting slide rod 310 that slides through the limiting plate 37. By fixing the first fixing rod 38 to the limiting plate 37, one curtain panel 31 located at the end is fixed. By allowing the limiting slide rod 310 to slide left and right through the limiting plate 37, the movement of multiple curtain panels 31 is guided and limited, improving the stability of the curtain panels 31 as they approach or move away from each other.

[0046] Diverting assembly 4 includes a herringbone diverting plate 41 located above the first conveyor belt 11 and a lifting rod 42 that drives the herringbone diverting plate 41 to slide up and down. The distance between the two sides of the herringbone diverting plate 41 located behind the swing assembly 2 increases in the direction away from the swing assembly 2. When the herringbone diverting plate 41 and the second conveyor belt 21 are aligned front to back, and there is little material in the area of ​​the first conveyor belt 11 behind the diverting assembly 4, the lifting rod 42 pulls the herringbone diverting plate 41 upward away from the first conveyor belt 11, so that the second conveyor belt 21 can transport the material to the area of ​​the first conveyor belt 11 where there is less material. Similarly, when the herringbone diverting plate 41 and the second conveyor belt 21 are aligned front to back, and there is a lot of material in the area of ​​the first conveyor belt 11 behind the diverting assembly 4, the lifting rod 42 pulls the herringbone diverting plate 41 upward away from the first conveyor belt 11. The herringbone diverter plate 41 moves downwards towards the first conveyor belt 11, causing the herringbone diverter plate 41 to divert the material conveyed by the second conveyor belt 21 to the left and right sides, thereby reducing the material input in areas with more material on the first conveyor belt 11 and avoiding blockage. The conveyor housing 12 is fixedly connected to a first mounting support rod 13 extending above the herringbone diverter plate 41, and the first mounting support rod 13 is fixedly connected to three support rod connecting plates 43 located above the triangular part of the herringbone diverter plate 41. The three lifting rods 42 located at the triangular part of the herringbone diverter plate 41 slide upwards through the three support rod connecting plates 43. By setting three lifting rods 42 and three support rod connecting plates 43 through which the lifting rods 42 slide up and down, the stability of the lifting support rods 42 driving the herringbone diverter plate 41 to slide up and down is improved.

[0047] As one implementation, the support rod connecting plate 43 has a through hole for the lifting rod 42 to pass through, and the inner wall of the through hole is in frictional contact with the outer wall of the lifting rod 42. By making frictional contact between the inner wall of the through hole and the outer wall of the lifting rod 42, the lifting rod 42 is kept stable after being pulled to a predetermined position, thereby keeping the herringbone diverter plate 41 stable. The upper end of the lifting rod 42 is fixedly connected to a lifting plate 44. The lifting plate 44 is designed to facilitate the operator to hold and pull the lifting rod 42.

[0048] As another implementation, a lifting electric cylinder 45 is fixedly installed on the support rod connecting plate 43, and the upper end of the lifting rod 42 is installed on the output end of the lifting electric cylinder 45. The lifting electric cylinder 45 drives the lifting rod 42 to slide up and down, thereby driving the herringbone diverter plate 41 to slide up and down.

[0049] Furthermore, a pressing plate 311 is fixedly connected to the end of the limiting slide bar 310 away from the second fixed rod 39, and a touch switch 312 electrically connected to the lifting cylinder 45 is fixedly connected to the end face of the pressing plate 311 near the limiting plate 37. When the baffle slab 31 is not fully unfolded, the touch switch 312 is away from the limiting plate 37, and the touch switch 312 is not subjected to external pressure and is in the open state. At this time, the touch switch 312 cannot control the lifting cylinder 45 to work. When there is too much material behind the herringbone diverter plate 41, the baffle slab 31 fully unfolds to completely block the second conveyor belt 21, making... The second conveyor belt 21 no longer conveys material to the area with excessive material on the first conveyor belt 11. The touch switch 312 moves to the limit plate 37 under the action of the pressing plate 311. The touch switch 312 switches to the closed state under the pressure of the limit plate 37. The touch switch 312 controls the lifting cylinder 45 to push the lifting rod 42 downward, so that the lifting rod 42 pushes the herringbone diverter plate 41 to stick to the first conveyor belt 11, thereby diverting the material at the first conveyor belt 11, thereby reducing the amount of material input in the area with excessive material on the first conveyor belt 11 and avoiding the problem of blockage.

[0050] A packaging machine includes the aforementioned material equalization control mechanism, and further includes a weighing mechanism located at the rear end of a conveyor 1. The weighing mechanism includes a coarse adjustment chain plate 52 and a fine adjustment synchronous belt 53 arranged in parallel, an inclined nylon pad 51 located at the front end of the coarse adjustment chain plate 52 and the fine adjustment synchronous belt 53 to ensure that the material reaches the fine adjustment synchronous belt 53 first, and a weighing shell 54 wrapped around the outside of the coarse adjustment chain plate 52 and the fine adjustment synchronous belt 53. The inclined nylon pad 51 ensures that the material reaches the fine adjustment synchronous belt 53 first, and under the same conditions, ensures that the fine adjustment synchronous belt 53 runs with full material. At the start of weighing, the coarse adjustment chain plate 52 and the fine adjustment synchronous belt 53 run at high speed. After reaching the set target, the coarse adjustment chain plate 52 changes to medium speed and finally stops running. When approaching the target weight, the fine adjustment synchronous belt 53 runs at low speed to ensure weighing accuracy and shorten the weighing time.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
