Description

Technical Field

[0001] This invention relates to the field of roll packaging technology, and more particularly to a roll packaging machine. Background Technology

[0002] When packaging roll materials with packaging film, a sealing and cutting packaging machine is generally used to package individual rolls. The film supply mechanism of the sealing and cutting packaging machine provides the packaging film, the pushing mechanism pushes the individual rolls backward onto the discharge conveyor, and the sealing and cutting mechanism heat-melts and cuts the packaging film. At this point, the packaging film is wrapped around the roll in a ring shape. Then, the sealing and cutting devices on both sides of the discharge conveyor seal the openings on both sides of the packaging film, completing the packaging. Finally, the individual rolls are transported to the palletizing area or loaded onto a truck.

[0003] The existing packaging film sealing and cutting methods can only seal one roll at a time, resulting in low packaging efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a roll packaging machine that can independently package three rolls side by side at a time, thereby improving packaging efficiency.

[0005] The technical solution adopted in this invention is: to provide a roll packaging machine, including a sealing and cutting packaging machine, a second sealing and cutting mechanism, a third sealing and cutting mechanism and a separating and transporting mechanism. The sealing and cutting packaging machine includes a feeding platform, a film feeding mechanism, a pushing mechanism, a first sealing and cutting mechanism and a discharge and transporting mechanism. The film feeding mechanism is used to wrap the packaging film around the outside of the roll, and the pushing mechanism is used to push the three rolls placed on the feeding platform to the discharge and transporting mechanism. A second sealing and cutting mechanism is provided on both the left and right sides of the discharge conveyor. A separating conveyor is provided on the side of the discharge conveyor away from the sealing and cutting packaging machine. The separating conveyor is used to separate the three rolls. A third sealing and cutting mechanism is provided on both the left and right sides of the separating conveyor. It also includes a limit structure for limiting the three rolls on the discharge conveyor mechanism.

[0006] To further optimize this technical solution, the separating transport mechanism includes three transport components, which are spaced apart in the left and right direction, with the middle transport component being higher than the left and right transport components. The height of the middle transport component corresponds to the height of the discharge transport mechanism. It also includes multiple pressure rollers located above the middle transport component. These pressure rollers are spaced apart in the front-to-back direction and are moved up and down together by an external lifting device. The pressure roller closest to the sealing and packaging machine is located above the discharge transport mechanism. During the downward pressing process, the pressure roller can squeeze and straighten the middle roll material, so that the middle roll material is located on the middle transport component. The third sealing and cutting mechanism on the left is used to seal and cut the packaging film between the left roll material and the middle roll material, and the third sealing and cutting mechanism on the right is used to seal and cut the packaging film between the right roll material and the middle roll material.

[0007] To further optimize this technical solution, the limiting structure includes two sets of limiting wheels located on the left and right sides of the discharge conveyor mechanism, and the limiting wheels are connected to the external telescopic rod.

[0008] To further optimize this technical solution, a left baffle is provided on the left side of the transport component located on the left side, and a right baffle is provided on the right side of the transport component located on the right side.

[0009] Further optimization of this technical solution includes two positioning guide rods. One positioning guide rod is provided on each of the left and right sides of the discharge conveyor mechanism. The positioning guide rods are higher than the discharge conveyor mechanism, and the two positioning guide rods are used to support the openings on the left and right sides of the packaging film, respectively.

[0010] Further optimization of this technical solution also includes: The feeding and conveying mechanism, located on one side of the sealing and packaging machine, is used to transport three rolls placed side by side to the feeding platform.

[0011] Further optimization of this technical solution also includes: The material transfer device is located on the side of the separating transport mechanism away from the material transfer mechanism, and is used to transport packaged rolls of material.

[0012] The beneficial effects of this invention are as follows: After the first sealing and cutting mechanism performs the sealing and cutting action, it can wrap three rolls of material in a ring-shaped packaging bag. After the second sealing and cutting mechanism performs the sealing and cutting action, it seals the left and right openings of the ring-shaped packaging bag, wrapping the three rolls of material in a fully sealed packaging bag to prevent the rolls of material from escaping from the side openings. After the third sealing and cutting mechanism performs the sealing and cutting action, it seals and cuts the middle of two adjacent rolls of material, packaging the three rolls of material separately. Each work cycle can complete the packaging of three rolls of material simultaneously, improving packaging efficiency.

[0013] After the third sealing and cutting mechanism performs the sealing and cutting action, the packaging film covering the middle roll of material has no burrs or excess material, and the surface is clean, so there is no need to cut off the excess material again.

[0014] At the same time, the three rolls of material are individually packaged. Inside the fully sealed packaging bag, the rolls on the left and right sides can be placed against the left and right sealing positions of the packaging film, which can better utilize the excess material on the left and right sides of the packaging film, making the control of packaging material usage relatively simple and more operable.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] like Figures 1-8 As shown, a roll packaging machine is used to package and seal three rolls placed side by side in a left-right direction. It includes a sealing and packaging machine 1, a second sealing and cutting mechanism 2, a third sealing and cutting mechanism 3, and a separating and transporting mechanism. It should be noted that... Figure 1 In the diagram, a represents the left, b represents the right, c represents the front, and d represents the back. The sealing and packaging machine 1 includes a feeding platform 101, a film feeding mechanism, a pushing mechanism 102, a first sealing and cutting mechanism 103, and a discharge and conveying mechanism 104. The film feeding mechanism is used to wrap the packaging film around the outside of the roll material. The pushing mechanism 102 can use an electric telescopic rod to drive the push plate to move, and is used to push the three roll materials placed on the feeding platform 101 to the discharge and conveying mechanism 104. A second sealing and cutting mechanism 2 is provided on both the left and right sides of the discharge transport mechanism 104. A separating transport mechanism is provided on the side of the discharge transport mechanism 104 away from the sealing and cutting packaging machine 1. The separating transport mechanism is used to separate the three rolls. A third sealing and cutting mechanism 3 is provided on both the left and right sides of the separating transport mechanism. It also includes a limiting structure for limiting the three rolls on the discharge conveyor 104. The limiting structure includes two sets of limiting wheels located on the left and right sides of the discharge conveyor 104 respectively. The limiting wheels are connected to an external telescopic rod. The position of the two sets of limiting wheels can be adjusted to limit the position of the three rolls, so that the middle roll can enter the designated position of the separating conveyor more accurately.

[0021] In use, three rolls of material are placed side by side on the feeding platform 101 in the left-right direction. The feeding platform 101 can be a transport mechanism or a fixed platform. The three rolls are positioned in the left-right direction by the telescopic side plate on the feeding platform 101 (such as by an electric telescopic rod). The pushing mechanism 102 can move back and forth to push the three rolls simultaneously to the discharge transport mechanism 104. The film supply mechanism of the sealing and packaging machine 1 provides packaging film to cover the lower, front and upper sides of the three rolls. The first sealing and cutting mechanism 103 welds and cuts the packaging film around the rolls. The three rolls are wrapped in the annular packaging bag 801. The annular packaging bag 801 has openings on the left and right sides (without welding and cutting). The film supply mechanism, the pushing mechanism 102, the discharge transport mechanism 104, the first sealing and cutting mechanism 103, the second sealing and cutting mechanism 2, and the third sealing and cutting mechanism 3 are all existing known technologies. Their working principles will not be described in detail here. For the sake of clearer illustration of the invention principle, the accompanying drawings and the process of use are omitted.

[0022] After the first sealing and cutting mechanism 103 is activated, the three rolls are located in the middle of the annular packaging bag 801. The discharge transport mechanism 104 continues to transport the annular packaging bag 801 and the three rolls inside forward. The openings on the left and right sides of the annular packaging bag 801 pass through the second sealing and cutting mechanisms 2 on the left and right sides respectively. The discharge transport mechanism 104 stops transporting and the second sealing and cutting mechanism 2 is activated to seal the left and right sides of the annular packaging bag 801, turning the annular packaging bag 801 into a fully sealed packaging bag 802. The discharge transport mechanism 104 continues to transport the fully sealed packaging bag 802 and the three rolls inside. After passing through the separation transport mechanism and the third sealing and cutting mechanism 3, the two third sealing and cutting mechanisms 3 seal and cut the middle position of every two adjacent rolls of the three rolls. The packaging film is welded and cut from top to bottom to form three independent roll packaging bags, completing the independent packaging of the three rolls.

[0023] The feeding platform 101 and the discharge conveyor 104 can be a conveyor belt, which uses friction to achieve left and right positioning of the roll material and packaging bag. A guide rod can also be set above the discharge conveyor 104 to guide the left and right position of the roll material and control the spacing of the three roll materials. When the three roll materials enter the discharge conveyor 104 from the feeding platform 101 and when the second sealing and cutting mechanism 2 seals the openings on the left and right sides of the annular packaging bag 801, the three roll materials can be in a close position to leave excess material for sealing and cutting the openings on both sides of the annular packaging bag 801. After sealing, the three roll materials can move left and right under the guidance of the guide rod in the fully sealed packaging bag 802, so that the two roll materials on the left and right sides are close to the left and right sides of the packaging bag respectively. Then, the third sealing and cutting mechanism 3 seals and cuts the packaging bag in the middle of each pair of roll materials.

[0024] The first sealing and cutting mechanism 103, the second sealing and cutting mechanism 2, and the third sealing and cutting mechanism 3 are all existing sealing and cutting mechanisms. They use upper and lower sealing and cutting blades arranged opposite each other to seal and cut the upper and lower packaging films together. The first sealing and cutting mechanism 103 is a conventional setting on the sealing and cutting packaging machine 1, which can realize the welding of the packaging film and the cutting at the middle of the weld. After welding, the second sealing and cutting mechanism 2 can cut or not, depending on whether to leave any excess material. When the third sealing and cutting mechanism 3 is activated, it can weld the upper and lower packaging films and then cut them at the middle of the weld, realizing the independent packaging of three rolls.

[0025] Furthermore, the separating transport mechanism includes three transport components 401, which are spaced apart in the left and right direction, and the middle transport component 401 is higher than the left and right transport components 401. The height of the middle transport component 401 corresponds to the height of the discharge transport mechanism 104. It also includes multiple pressure rollers 5 located above the middle transport component 401. The multiple pressure rollers 5 are arranged at intervals in the front-to-back direction. The multiple pressure rollers 5 are driven by an external lifting device to move up and down together. Among them, the pressure roller 5 closest to the sealing and packaging machine 1 is located above the discharge transport mechanism 104. During the downward pressing process, the pressure roller 5 can squeeze and correct the middle roll material, so that the middle roll material is located on the middle transport component 401. The transport component 401 is existing known technology and will not be described in detail here.

[0026] During operation, the middle roll of material on the material conveying mechanism 104 corresponds to the middle conveying component 401, and the rolls on the left and right sides fall onto the left and right conveying components 401 respectively. The third sealing and cutting mechanism 3 on the left is used to seal and cut the packaging film between the left roll and the middle roll, and the third sealing and cutting mechanism 3 on the right is used to seal and cut the packaging film between the right roll and the middle roll.

[0027] When in use, the separating transport mechanism can separate the three rolls of material inside the fully sealed packaging bag 802 in the left and right directions, which facilitates the operation of the third sealing and cutting mechanism 3. The packaging film between adjacent rolls is not completely taut, and the packaging bag is relatively loose in the left and right directions as a whole.

[0028] Of the three transport components 401, the middle position is high and the two sides are low. The rolls on the left and right sides fall onto the transport components 401 on the left and right sides respectively by gravity. Compared with the method of separating by pushing the rolls to move left and right with levers, this can reduce the scratching of the outer surface of the packaging film. The discharge transport mechanism 104 transports three rolls of material to the separating transport mechanism. The middle transport component 401 is flush with the discharge transport mechanism 104. The position of the middle roll of material is opposite to that of the middle transport component 401. Multiple pressure rollers 5 can be moved downward by an external lifting device. The pressure rollers 5 located above the discharge transport mechanism 104 can adjust the middle roll of material before it moves onto the transport component 401. The middle of the pressure roller 5 is set to be concave inward. The middle roll of material can be moved to correspond with the middle transport component 401 by the squeezing of the inclined surface. When the middle roll of material enters the middle transport component 401, the rolls on the left and right sides fall onto the left and right transport components 401 respectively as they continue to move forward, thus separating the three transport components 401. The pressure rollers 5 can stably limit the position of the middle roll of material and prevent the middle roll of material from shifting when the rolls on the left and right sides fall to the sides.

[0029] The left and right spacing between the transport components 401 is adapted to the diameter of the roll material, and the narrowest point must be able to accommodate the lifting and lowering action of the third sealing and cutting mechanism 3. This can be achieved by setting and adjusting the height and left and right spacing between the transport components 401 through external mounting brackets. At the same time, the initial position of the lower sealing and cutting component of the third sealing and cutting mechanism 3 (which is moved relative to the upper sealing and cutting blade to perform the sealing and cutting action) can be located between the two transport components 401 and higher than the left or right transport component 401, but lower than the middle transport component 401. When the roll material rolls to both sides, the lower sealing and cutting component can act as a limiting support to prevent the roll material from getting stuck between the two transport components 401. A left baffle 402 is provided on the left side of the transport component 401 located on the left, and a right baffle 403 is provided on the right side of the transport component 401 located on the right. The left baffle 402 and the right baffle 403 limit the movement on the left and right sides of the separating transport mechanism, which can prevent the roll material from rolling off the side. The transport component 401 can be a belt conveyor or a concave roller conveyor, etc.

[0030] Furthermore, it also includes two positioning guide rods 1041. One positioning guide rod 1041 is provided on each of the left and right sides of the discharge conveying mechanism 104. The positioning guide rods 1041 are higher than the discharge conveying mechanism 104. The two positioning guide rods 1041 are used to support the left and right openings of the packaging film respectively. The left and right openings of the annular packaging film are located on the upper side of the positioning guide rods 1041 on the left and right sides respectively.

[0031] When in use, the positioning guide rods 1041 on the left and right sides of the material conveying mechanism 104 can support and limit the openings on the left and right sides of the annular packaging film 801, so that the second sealing and cutting mechanism 2 can seal the openings on both sides.

[0032] Furthermore, it also includes: The feeding and transporting mechanism 6 is located next to the sealing and packaging machine 1 and is used to transport three rolls placed side by side to the feeding table 101.

[0033] The material transfer device 7 is located in front of the separating transport mechanism and is used to transport individually packaged rolls.

[0034] In use, the loading and transporting mechanism 6 and the unloading and transfer device 7 enable automated assembly line operation. The loading and transporting mechanism 6 transports three rolls of material side by side to the feeding table 101 at the same time, and the unloading and transfer device 7 transports the three rolls of material after packaging to the next work station.
