Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, specifically to an adjustable packing machine. Background Technology

[0002] In modern industrial production and logistics, packing machines, as key equipment for efficient cargo packaging, play a vital role in improving production efficiency and reducing labor costs. They can quickly and reliably complete the packing and sealing process, greatly enhancing the automation level of logistics operations.

[0003] Currently, traditional packing machines mostly use a fixed-specification operating mode during the packing and sealing of goods. In the packing stage, goods are usually manually moved into the carton or a simple mechanical pushing device is used, lacking a precise gripping and placement mechanism, making it difficult to ensure that the goods are neatly arranged inside the carton. In the sealing stage, the sealing components of traditional packing machines often cannot be flexibly adjusted according to the size of the carton.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an adjustable packing machine. Through modular adjustment mechanism, multi-station collaborative transmission, precise positioning of carton packing and adaptive sealing technology, it can realize the rapid adaptation of carton width and height, precise positioning of goods packing and dynamic adjustment of flap pressing and tape sealing, thereby improving equipment compatibility, packaging efficiency and stability.

[0006] Technical Solution: This utility model provides an adjustable packing machine comprising: a frame, on which a transmission mechanism is provided, the transmission mechanism including a first station and a second station, the first station and the second station being arranged sequentially along the X direction, the transmission mechanism being used to transport empty cartons to the first station for packing goods, and then to the second station for sealing; a packing assembly, the packing assembly being disposed on the frame, including a placement platform, a pushing mechanism, and a box-infeeding mechanism, the placement platform, the pushing mechanism, and the box-infeeding mechanism being disposed on the frame and beside the transmission mechanism, the placement platform being used to place goods, the pushing mechanism being used to push goods along the Y direction to the box-infeeding mechanism, the box-infeeding mechanism being used to grab goods in the Z direction and pack them into empty cartons on the first station; and a sealing assembly, the sealing assembly being disposed above the second station, being used to adjust according to the size of the cartons and to seal the cartons with tape. This conveying mechanism enables the orderly transport of empty cartons. First, the empty cartons are transported to the first station for packing. After packing, the cartons are transported to the second station for sealing, thus forming a continuous packaging process. The sealing component is located above the second station and can be flexibly adjusted according to the size of the cartons. The cartons are sealed using tape to ensure that the sealing effect meets the packaging requirements of different carton sizes.

[0007] Furthermore, in an adjustable packing machine of this application, the transmission mechanism includes a pair of side plates, with a plurality of rollers disposed between the pair of side plates. The rollers are arranged in parallel and spaced apart, and are drively connected to the side plates. The carton is placed on the rollers and moves along the X-direction after the rollers rotate. The contact between the rollers and the carton is point contact or line contact, which greatly reduces the friction area with the carton compared to the surface contact of traditional planar conveyor belts. During the carton transmission process, wear on the carton surface can be effectively reduced.

[0008] Furthermore, in an adjustable packing machine of this application, the pushing mechanism includes a first cylinder, the output end of which is connected to a push plate. A pair of limiting partitions are provided on the loading platform. These limiting partitions are V-shaped and located below the transfer box mechanism. The push plate is used to push goods placed on the loading platform from the V-shaped opening into the transfer box mechanism below. The two limiting partitions, away from the V-shaped opening, are connected by a baffle. The cooperation between the V-shaped limiting partitions and the push plate provides clear guidance for pushing the goods. The limiting structure formed by the limiting partitions and the baffle protects the goods during the pushing process. When the push plate pushes the goods, the goods are restricted to move within a stable area.

[0009] Furthermore, in an adjustable packing machine of this application, the box-infeeding mechanism includes a pair of slide rails. These slide rails are mounted on a frame along the Y-direction and above the rollers and the shelf. A top plate is slidably connected to the slide rails. The top plate is driven to move along the Y-direction by a second cylinder mounted on the frame. A set of guide pillars passes through the top plate along the Z-direction. A carrier plate is connected to the guide pillars below the top plate. A set of suction cups is mounted on the carrier plate, facing the shelf. A first motor is also mounted on the top plate, and the first motor is connected to the carrier plate, driving the carrier plate to move along the Z-direction. Through the coordinated operation of the second cylinder and the first motor, the suction cups can move flexibly in both the Y and Z directions, accurately positioning the goods on the shelf and gripping them. The goods are then transferred to an empty carton at the first workstation, completing the gripping and packing operation.

[0010] Furthermore, in an adjustable packing machine of this application, the sealing assembly includes a width adjustment mechanism. This mechanism comprises a pair of second guide posts and a pair of guide grooves. The second guide posts pass through a pair of side plates and are located below the rollers. A pair of connecting members are sleeved on the second guide posts, correspondingly connected to the guide grooves. The pair of guide grooves are arranged along the X-direction and located above the rollers. One end of each second guide post has an adjustment handle. Rotating the adjustment handle adjusts the movement of the pair of connecting members towards or away from each other, thereby adjusting the opening and closing of the pair of guide grooves. The guide grooves, being arranged along the X-direction and adjustable in opening and closing, can position and guide the cartons during transport. When cartons of different widths move to the second station on the rollers, the spacing between the guide grooves on both sides can be adjusted according to the width of the cartons, confining the cartons to a suitable position and preventing them from shifting during the sealing process.

[0011] Furthermore, in an adjustable packing machine of this application, a plurality of rollers are provided in the guide groove. The rollers are tumblingly connected to the side wall of the carton, and the rollers are made of rubber. The rubber rollers have good elasticity, and when the carton comes into contact with the rollers during transport, the rollers can cushion the movement of the carton through their own elastic deformation.

[0012] Furthermore, in an adjustable packing machine according to this application, the sealing assembly further includes a height adjustment mechanism. The height adjustment mechanism includes a pair of uprights, each mounted on the outer side of a side plate and arranged along the Z-direction. A second motor is mounted at the bottom of each upright, and a lead screw is connected to the output end of the second motor. A connecting piece is threaded onto the lead screw, and a crossbar connects the two connecting pieces. The crossbar spans across the pair of side plates. A pressing mechanism is mounted on the side of the crossbar closest to the packing assembly, and a sealing mechanism is mounted on the side furthest from the packing assembly. The pressing mechanism is used to press the carton flap closed, and the sealing mechanism is used to seal the closed carton. The connecting piece is driven by the second motor to move in the Z-direction, thereby driving the pressing mechanism and the sealing mechanism to move in the Z-direction, thus adapting to cartons of different heights. Through the height adjustment mechanism, the packing machine can adapt to various carton heights, effectively sealing both short and tall cartons. Enterprises do not need to purchase multiple dedicated sealing machines for cartons of different heights.

[0013] Furthermore, in an adjustable packing machine of this application, the pressing mechanism includes a support rod, a third cylinder, and a pressure rod. The support rod is vertically mounted on a crossbar and extends along the X direction toward the packing assembly. The third cylinder is mounted on the support rod, and its output end is connected to the support rod via a connecting rod. The pressure rod is mounted on the connecting rod, and the third cylinder drives the connecting rod to rotate, thereby driving the pressure rod to rotate. A pair of levers are also mounted on the support rod. The levers are in a V-shape, and the opening angle of the V-shape is adjustable. A pressure guide plate is also mounted on the lower side of the support rod. When a carton containing goods moves along the X direction to the pressing mechanism, the pressure guide plate first contacts the upper flap of the carton. As the carton moves, the upper flap is flattened by the pressure guide plate. Then, the third cylinder drives the connecting rod to rotate the pressure rod clockwise, flattening the other side of the upper flap corresponding to the one flattened by the pressure guide plate. The carton continues to move along the X direction, and the pair of levers fold and flatten the upper flaps on both sides of the carton. The lever in the pressing mechanism is V-shaped and its opening angle is adjustable, allowing the mechanism to flexibly adjust the angle of the lever to accommodate paper boxes of different sizes and shapes.

[0014] Furthermore, in an adjustable packing machine of this application, the sealing mechanism includes a sealing frame, a tape pulley, an intermediate pulley group, a sealing wheel, and a cutter. The sealing frame is mounted on a crossbar. The intermediate pulley group includes multiple rollers, which guide the tape to the non-stick side of the tape and attach it to the sealing wheel. The sealing wheel is mounted on the sealing frame. Cutting plates are mounted on both sides of the cutter and are mounted on the sealing frame. The tape roll is inserted into the tape pulley. After the tape head passes through the intermediate pulley group, the non-stick side is attached to the sealing wheel. When the carton moves along the X direction, the tape first adheres to the side wall of the carton, and the sealing wheel rotates and slides from the side wall of the carton to the top surface of the carton. Then, the tape seals the carton along the seam between the two upper flaps. The tape continues to be conveyed until it slides off the top surface of the carton. The sealing wheel then falls to drive the cutter to cut the tape, thus completing the sealing.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0016] 1. The adjustable packing machine of this utility model achieves fully mechanized operation from carton conveying and cargo packing to sealing through the automated collaborative operation of the conveying mechanism, the carton packing component, and the sealing component. The roller design of the conveying mechanism, combined with the orderly layout of the first and second workstations, can automatically convey empty cartons to the carton packing station and then transfer them to the sealing station after packing, reducing manual handling. In the carton packing component, the pushing mechanism and the carton transfer mechanism work together precisely to achieve automated grabbing and loading of goods from the platform to the carton. The sealing component, through the linkage of the width adjustment mechanism, the height adjustment mechanism, the carton pressing mechanism, and the sealing mechanism, can automatically adjust the sealing position according to the carton size, complete the flip-top pressing and tape sealing, greatly improve packing efficiency and reduce manual labor intensity.

Detailed Implementation

[0027] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-5 As shown, an adjustable packing machine includes a frame 1, on which a transmission mechanism 2, a packing assembly 3, and a sealing assembly 4 are provided.

[0030] I. Structure and Operation of Transmission Mechanism 2

[0031] The conveying mechanism 2 includes a first station 21 and a second station 22 arranged sequentially along the X direction for conveying empty cartons and switching between stations. A pair of side plates 23 are fixed parallel to both sides of the frame 1, and several rollers 24 are evenly arranged between the side plates 23. The rollers 24 are connected to the side plates 23 by a transmission mechanism. The cartons are placed on the rollers 24 and move along the X direction as the rollers 24 rotate. The first station 21 is used for packing goods, and the second station 22 is used for sealing cartons. The automatic transfer of cartons between the two stations is achieved by the rotation of the rollers 24.

[0032] II. Precise positioning and gripping of packing component 3

[0033] The packing assembly 3 is located next to the transfer mechanism 2 and includes a platform 31, a pushing mechanism 32, and a box-in mechanism 33.

[0034] The platform 31 is used to place goods to be packed. It is equipped with a pair of figure-eight shaped limiting partitions 311. The open end of the figure-eight shape faces the box-moving mechanism 33, and the end away from the open end is connected by a baffle 312 to form a goods positioning area.

[0035] Pushing mechanism 32: includes a first cylinder 321 and a push plate 322. The first cylinder 321 is fixed to the frame 1, and its output end is connected to the push plate 322. When the goods are placed in the limiting partition 311 of the shelf 31, the first cylinder 321 drives the push plate 322 to move along the Y direction, pushing the goods from the figure-eight opening end to the bottom of the loading box mechanism 33.

[0036] The box-in mechanism 33 consists of a pair of slide rails 331 mounted along the Y-direction above the rollers 24 and the platform 31. A top plate 332 is slidably connected to the slide rails 331. The top plate 332 is driven to move along the Y-direction by a second cylinder 333 mounted on the frame 1. Four guide pillars 334 pass through the top plate 332 along the Z-direction. The lower ends of the guide pillars 334 are connected to a carrier plate 335, and suction cups 336 facing the platform 31 are mounted on the carrier plate 335. A first motor 337 on the top plate 332 is connected to the carrier plate 335 and drives the carrier plate 335 to rise and fall along the Z-direction. When the goods are pushed below the box-in mechanism 33, the first motor 337 drives the carrier plate 335 to descend, the suction cups 336 pick up the goods, and then the second cylinder 333 drives the top plate 332 to move along the Y-direction above the first workstation 21. The first motor 337 then actuates again to accurately place the goods into the empty carton.

[0037] III. Adaptive Adjustment of Sealing Component 4 and Sealing Process

One end of the second guide post 411 is provided with an adjustment handle 4111, and the other end is fitted with a connector 413. The connector 413 is connected to the guide groove 412 above the roller 24. Rotating the adjustment handle 4111 can drive the connector 413 to move towards or away from each other along the second guide post 411, thereby adjusting the opening and closing width of the guide groove 412. Multiple rubber rollers 4121 are provided in the guide groove 412, which roll in contact with the side wall of the carton, which can both position the carton and reduce transmission friction.

[0040] Height adjustment mechanism 42: A pair of uprights 421 are installed on the outside of the side plate 23 along the Z direction. The second motor 422 at the bottom of the uprights 421 drives the lead screw 423 to rotate. The connecting piece 424 on the lead screw 423 rises and falls along the Z direction. The crossbar 425 between the connecting pieces 424 moves accordingly, thereby driving the pressing mechanism 43 and the sealing mechanism 44 installed on the crossbar 425 to adapt to cartons of different heights.

[0041] The box-pressing mechanism 43 consists of a support rod 431 vertically fixed to the crossbar 425 and extending towards the box-packing assembly 3. A third cylinder 432 is mounted on the support rod 431, and the third cylinder 432 is connected to the pressure rod 433 via a connecting rod 434. A pressure guide plate 436 is located below the support rod 431, and V-shaped levers 435 (with adjustable opening angles) are located on both sides. When the carton moves to the bottom of the box-pressing mechanism 43, the pressure guide plate 436 first contacts and flattens the top flap of the carton. Then, the third cylinder 432 drives the connecting rod 434 to rotate, and the pressure rod 433 flattens the top flap on the other side. Finally, the levers 435 fold in half to flatten both top flaps.

[0042] Sealing mechanism 44: Sealing frame 441 is fixed to crossbar 425. The tape on the tape pulley 442 passes through the intermediate pulley group 443, and the non-stick side is attached to the sealing wheel 444. After the carton is closed, the tape is first attached to the side wall of the carton. The sealing wheel 444 moves with the carton and slides along the side wall to the upper surface. The tape is attached along the upper flap seam. When the carton continues to be conveyed until the tape leaves the upper surface, the sealing wheel 444 drives the cutter 445 to cut the tape between the cutter plates 446, completing the sealing of the carton.

[0043] IV. Work Process Summary

[0044] Empty cartons are conveyed to the first station 21 by rollers 24. Goods on the platform 31 are pushed by the pushing mechanism 32 and picked up by the box-in-carton mechanism 33 and put into cartons. The cartons are then transferred to the second station 22. The width adjustment mechanism 41 positions the cartons through the guide groove 412 and rollers 4121. The height adjustment mechanism 42 drives the pressing mechanism 43 and the sealing mechanism 44 to the appropriate height. The pressing mechanism 43 presses down the top flap in sequence, and the sealing mechanism 44 completes the tape pasting and cutting, finally realizing the automated packaging of cartons of various specifications.
