Description

TECHNICAL FIELD

[0001] The utility model relates to packing box packing equipment technical field, especially in a kind of easy pull formula candy box packaging equipment. BACKGROUND

[0002] In candy scale production, easy pull formula candy box becomes one of mainstream packaging forms due to the characteristics of convenient opening and exquisite appearance, and its packaging needs to complete the continuous flow of box positioning, candy filling, cover down, sealing packaging, and the automation precision and process synergy of equipment are extremely high. However, the existing candy box cover equipment has many technical shortcomings, and it is difficult to meet the efficient and high-quality production needs:

[0003] Firstly, the box body conveying and candy discharging synergy are poor: most equipment lacks precise control mechanism, and the box body is easy to be misaligned due to position deviation during conveying, which needs manual adjustment.

[0004] Secondly, the control precision of cover discharging is insufficient: the existing equipment mostly relies on simple gravity discharging, and lacks targeted control structure, which is easy to cause multiple covers to fall or miss simultaneously.

[0005] Finally, the process connection is faulted: there is no coherent control mechanism for box entering, packaging and box exiting, and the front and rear stations are easy to be empty or stacked, which causes poor equipment stability during batch production, frequent manual intervention, significantly increased labor cost and restricted production efficiency improvement. UTILITY MODEL CONTENT

[0006] The utility model solves the problem of providing an easy pull formula candy box packaging equipment, which can accurately control the discharging, cover installation and packaging, realize cyclic continuous operation and improve production efficiency.

[0007] In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows:

[0008] The application relates to an easy-pull candy box packaging equipment, which comprises a rack, a box body conveying mechanism, a candy discharging mechanism, a box cover discharging mechanism and a box conveying turntable, the box body conveying mechanism is installed on the rack, the candy discharging mechanism, the box cover discharging mechanism and the box conveying turntable are sequentially arranged on the rack from front to back and are all above the box body conveying mechanism; the equipment is characterized in that the equipment further comprises a discharging box blocking mechanism, a box cover blocking control mechanism, a box conveying control mechanism and a cover sealing mechanism which are arranged on the rack, the discharging box blocking mechanism is arranged on one side of the box body conveying mechanism, the power output end of the discharging box blocking mechanism is perpendicular to the conveying direction of the box body conveying mechanism and can be telescoped above the box body conveying mechanism, the power output end of the discharging box blocking mechanism is located at the rear side of the discharging end of the candy discharging mechanism; the box cover blocking control mechanism is arranged on the front side of the box cover discharging mechanism, the power output end of the box cover blocking control mechanism is directed below the cover discharging end of the box cover discharging mechanism and can be telescoped forward and backward below the cover discharging end of the box cover discharging mechanism; a plurality of arc-shaped gaps capable of accommodating the box bodies are uniformly arranged on the outer edge of the box conveying turntable along the circumferential direction, the outer edge of the box conveying turntable is sequentially provided with a box conveying position, a packaging position and a box discharging position corresponding to the corresponding arc-shaped gaps along the circumferential direction, the arc-shaped gap on the box conveying position corresponds to the feeding end of the box body conveying mechanism, the cover discharging end of the box cover discharging mechanism is located directly above the box conveying position, the cover sealing mechanism is arranged on the packaging position, and the arc-shaped gap on the box discharging position corresponds to the discharging end of the box body conveying mechanism; the box conveying control mechanism is arranged on one side of the box cover discharging mechanism, the power output end of the box conveying control mechanism is perpendicular to the conveying direction of the box body conveying mechanism and can be telescoped above the box body conveying mechanism, and the power output end of the box conveying control mechanism is located at the front side of the box conveying position and below the power output end of the box cover blocking control mechanism.

[0009] The above definitions of front and rear: the conveying direction of the box body on the box body conveying mechanism is used as the reference, the side where the box body arrives first is the front, and the side where the box body arrives last is the rear.

[0010] The above candy box comprises a box body and a box cover. Before packaging, the whole stack of box covers is placed in the box cover discharging mechanism, the power output end of the box cover blocking control mechanism is driven to extend towards the cover discharging end of the box cover discharging mechanism, and just covers the cover discharging end of the box cover discharging mechanism, so as to avoid the whole stack of box covers from falling down from the cover discharging end of the box cover discharging mechanism; meanwhile, the power output end of the discharging box blocking mechanism and the power output end of the box conveying control mechanism are all in the retracted state (not above the box body conveying mechanism).

[0011] When the candy boxes are placed in the candy box conveying mechanism in sequence, the candy boxes are conveyed to the candy dispensing mechanism. When the candy boxes are conveyed to the lower side of the candy dispensing mechanism, the power output end of the candy box blocking mechanism extends to the upper side of the candy box conveying mechanism to block the backward conveying of the candy boxes, so that the candy boxes stop right below the candy dispensing mechanism, and the candy dispensing mechanism fills the candy boxes with candies. Then, when the candy boxes are filled with candies, the power output end of the candy box blocking mechanism retracts to the outside of the candy box conveying mechanism, and the candy box conveying mechanism continues to convey the candy boxes to the candy box feeding station. When the candy boxes are conveyed to the arc-shaped gap on the candy box feeding station and are below the box cover dispensing mechanism, the candy box feeding turntable temporarily stops rotating, the box cover blocking mechanism retracts to the outside of the candy box conveying mechanism, the cover dispensing mechanism opens the cover end, and the lowest box cover of the cover dispensing mechanism falls onto the opening of the candy box filled with candies. At the same time, the power output end of the candy box feeding control mechanism extends to the upper side of the candy box conveying mechanism to prevent the backward conveying of the next candy box filled with candies. After the last candy box is covered, the candy box feeding turntable rotates to transfer the candy box with the covered box cover to the sealing station, the sealing mechanism seals the box cover on the opening of the candy box, and the sealing between the box cover and the candy box is ensured. At the same time, the arc-shaped gap is rotated to the candy box feeding station, the power output end of the candy box feeding control mechanism retracts to the outside of the candy box conveying mechanism, and the next candy box filled with candies is conveyed to the arc-shaped gap. Finally, the candy box feeding turntable rotates to transfer the sealed candy box to the candy box output station, and the sealed candy box is separated from the arc-shaped gap and is output from the discharge end of the candy box conveying mechanism, so as to output the candy box product in a cycle.

[0012] Generally, the intermittent rotation of the candy box feeding turntable is driven by a turntable driving mechanism. The turntable driving mechanism includes a driving motor and a rotating shaft. The rotating shaft is rotatably installed on the rack and is arranged in the up-down direction.

The front vertical guide plate plays a role of auxiliary guiding, and can guide the box on the box conveying mechanism into the arc-shaped gap of the box feeding turntable; then, the arc-shaped gap of the box feeding turntable and the fixed arc-shaped guardrail form a dynamic guiding path, which limits the box transferred from the box feeding station to the packaging station, preventing the box to be packaged from flying out during the transfer process; finally, the rear vertical guide plate also plays a role of auxiliary guiding, and can guide the box on the box discharging station to the discharge end of the box conveying mechanism for output.

The blocking cylinder drives the blocking seat and the blocking plate to move forward and backward below the cover discharging end of the box cover feeding mechanism, so as to block the lowermost box cover in the feeding channel in the form of drawer pulling.

[0016] In the further preferred solution, the blocking plate comprises two front and rear support strips and two blocking pieces; the front ends of the two support strips are mounted on the blocking seat; the two blocking pieces are mounted on the rear ends of the corresponding support strips; the feeding opening is located above the two support strips; and when the blocking plate is in the extended state, the two blocking pieces are located below the area of the feeding opening, respectively. The two support strips are symmetrically distributed, and the blocking pieces at the rear ends correspond to the area below the feeding opening, forming a two-point symmetric support structure: when the stacked box cover is placed in the feeding channel, the two side edges of the lowermost box cover can be lifted by the two blocking pieces at the same time, avoiding the problem of uneven force on the box cover and tilting and mispositioning of the stacked box cover caused by single-sided support of the traditional single blocking plate.

[0018] Generally, the distance between the lower end surface of the cover pressing column and the tray is constant during packaging, and the second lifting driving mechanism does not need to be driven to adjust the lifting of the pressing column each time.

When the cam is rotated to the short diameter side of the wheel surface corresponding to the transmission bearing at the upper end of the rolling wheel, the short diameter side of the cam is not in contact with the transmission bearing, the rolling wheel is separated from the lid, and the arc-shaped concave surface is separated from the lid after being sealed, so as to be sequentially sealed by the arc-shaped concave surfaces of the rolling wheels.
