Technical Field

[0001] The utility model relates to the field of packaging film feeding devices, in particular to a packaging film conveying and leveling device. Background Art

[0002] Packaging film is a flexible sheet material that can be used to prepare packaging bags in industrial packaging.

[0003] When the packaging film is unfolded, it is in a long and continuous form. When storing the packaging film, it is usually gradually rolled into a roll for storage. In the automated production process of the equipment, the rolled packaging film needs to be unfolded and transported to a preset position for cutting. The cut packaging film can be prepared into packaging bags by folding in half, sealing the edges, etc. Since wrinkles are easily generated when the packaging film is manufactured or wrinkles are easily generated during the transportation of the packaging film, the wrapping effect and appearance of the prepared packaging bag are affected.

[0063] In this embodiment, the first leveling assembly 2 includes two first rotating shafts 22, which are arranged at intervals along the conveying direction of the packaging film. The first belt 21 is annularly sleeved on the two first rotating shafts 22. One of the two first rotating shafts 22 is driven to rotate by the driving mechanism 4. The driving mechanism 4 drives the first belt 21 through a transmission connection with the first rotating shaft 22, so that the first belt 21 performs a circular motion.

[0064] The working process of the first leveling component 2 of the present application scheme is:

[0065] Loading: The packaging film enters the first channel of the first flattening assembly 2. One surface of the packaging film contacts the first belt 21.

[0066] Conveying: After the driving mechanism 4 is started, it drives the first rotating shaft 22 to rotate. The rotation of the first rotating shaft 22 drives the first belt 21 to move in an annular manner. The packaging film is clamped by the first belt 21 and continuously conveyed along the conveying direction.

[0067] The present application achieves the following effects by setting the first leveling assembly 2:

[0068] The first leveling assembly 2 realizes efficient conveying and leveling of the packaging film through two first rotating shafts 22 and an annular first belt 21. Due to the annular design of the belt, the contact surface is larger and the leveling effect is better.

[0069] The design of the two first rotating shafts 22 makes the movement of the first belt 21 more stable and reduces shaking and deviation.

[0070] In some embodiments, when a longer first belt 21 is provided, a plurality of driven rotating shafts may be provided between the two first rotating shafts 22 to rotate along with the first belt 21 , thereby supporting the first belt 21 .

[0072] The driving mechanism 4 is drivingly connected to one of the two second rotating shafts 32 .

[0073] In this embodiment, the second leveling assembly 3 includes two second rotating shafts 32, which are arranged at intervals along the conveying direction of the packaging film.

The driving mechanism 4 is connected to and drives one of the two second rotating shafts 32, so that the second belt 31 and the other second rotating shaft 32 move.

[0074] The working process of the second leveling component 3 of the present application scheme is as follows:

[0075] Loading: The packaging film enters the first channel formed by the first belt 21 and the second belt 31 through an external loading device. The upper surface of the packaging film contacts the second belt 31, and the lower surface contacts the first belt 21.

[0076] Conveying: After the driving mechanism 4 is started, it can drive the second rotating shaft 32 to rotate, driving the second belt 31 to move in an annular manner, and at the same time, the first rotating shaft 22 drives the first belt 21 to move in an annular manner. It should be noted that the first belt 21 and the second belt 31 have the same movement direction.

[0077] The packaging film is clamped by the first belt 21 and the second belt 31 and is continuously conveyed forward.

[0078] Leveling: During the movement, the packaging film is subjected to uniform pressure from the first belt 21 and the second belt 31 and is gradually leveled.

[0080] Please continue to refer to Figure 2 In some embodiments, the packaging film conveying and leveling device provided in the embodiment of the utility model further includes at least one third leveling component 5 disposed on the support 1, and the third leveling component 5 includes a first roller 51 and a second roller 52, wherein:

[0081] The first roller 51 and the second roller 52 are rotatably connected to the support 1, and a second channel is formed between the first roller 51 and the second roller 52. The second channel corresponds to the first channel and is used for the packaging film to pass through. The first roller 51 and the second roller 52 respectively abut against two opposite surfaces of the packaging film in the second channel.

[0082] In this embodiment, the third flattening assembly 5 includes a first roller 51 and a second roller 52, which are rotatably connected to the support 1. A second channel is formed between the first roller 51 and the second roller 52, and the second channel corresponds to the first channel and is used for the packaging film to pass through. The first roller 51 and the second roller 52 contact two opposite surfaces of the packaging film respectively. The first roller 51 and the second roller 52 can be rotated passively by an external driving device or due to the movement of the packaging film to achieve the extrusion and flattening of the packaging film.

[0083] The working process of the third leveling component 5 of the present application solution is:

[0084] Loading: The packaging film enters the second channel through the front-stage flattening assembly. The two opposite surfaces of the packaging film contact the first roller 51 and the second roller 52 respectively.

[0085] Conveying: As the packaging film moves, the first roller 51 and the second roller 52 rotate relative to the connection point of the support 1, and the first roller 51 and the second roller 52 contact the packaging film and continuously convey the packaging film forward. When the packaging film passes between the rollers, it is evenly squeezed and tensioned.

[0086] Leveling: During the conveying process, the packaging film is further leveled by the squeezing action of the first roller 51 and the second roller 52. By adjusting the spacing and pressure between the rollers, it can be adapted to packaging films of different thicknesses and materials to ensure a leveling effect.

[0087] The present application achieves the following effects by setting the third leveling assembly 5 of the above structure:

[0088] Efficient leveling: The third leveling component 5 provides an additional leveling step, so that the packaging film is subjected to multiple leveling treatments when passing through the device, and the leveling effect is better. The problem of incomplete leveling that may exist in a single leveling component is avoided, and the leveling quality is improved.

[0089] Enhanced stability: The roller design allows the packaging film to be evenly stressed during transportation, reducing vibration and deviation, ensuring smooth transportation of the packaging film. The setting of multiple leveling components allows the packaging film to be effectively leveled at different positions, making it more stable.

[0090] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the packaging film conveying and leveling device proposed in the embodiments of the utility model includes multiple third leveling components 5 and multiple transition pieces 6. The third leveling components 5 are arranged horizontally at intervals. The first roller 51 of each third leveling component 5 is located below the second roller 52. A transition piece 6 is arranged between two adjacent third leveling components 5. The transition piece 6 is arranged on the support 1 and is located between the bottom of the second roller 52 and the top of the first roller 51. The transition piece 6 is used to support the packaging film between two adjacent third leveling components 5.

[0091] In this embodiment of the packaging film conveying and leveling device, a plurality of third leveling assemblies 5 are horizontally spaced apart and arranged on the support 1, and each third leveling assembly 5 comprises a first roller 51 and a second roller 52 located above the first roller 51. A transition piece 6 is arranged on the support 1, below each second roller 52, and there is a transition piece 6 between any two adjacent first rollers 51. The transition piece 6 is used to support the packaging film so that it can be additionally supported and stabilized during the leveling process.

[0092] Each third flattening assembly 5 is rotated passively by an external driving device or due to the movement of the packaging film. The transition piece 6 provides physical support to ensure that the packaging film remains flat during the transition between the rollers.

[0093] After passing through the first flattening assembly 2 and the second flattening assembly 3 of the front section, the packaging film enters the area consisting of a plurality of third flattening assemblies 5 and transition pieces 6. When the packaging film enters each third flattening assembly 5, its upper surface contacts the second roller 52 and its lower surface contacts the first roller 51.

[0094] With the operation of the driving mechanism 4, the packaging film is continuously conveyed and flattened between each third flattening assembly 5. The coordinated movement of the first roller 51 and the second roller 52 applies uniform pressure to the packaging film, and flattens it step by step.

[0095] Between two adjacent first rollers 51, the packaging film is transitioned through a transition piece 6 to prevent the packaging film from sagging or wrinkling between the two rollers. The transition piece 6 provides physical support so that the packaging film remains flat when moving from one third flattening assembly 5 to the next assembly without hanging or sagging.

[0096] The packaging film always maintains uniform force during the entire conveying and leveling process, avoiding poor leveling effect caused by uneven transition.

[0097] The present application achieves the following effects by setting the third leveling assembly of the above structure:

[0098] First, the leveling effect is improved: through the arrangement of multiple third leveling components 5, the packaging film is leveled multiple times during the conveying process, and the leveling effect is significantly improved. Each leveling component further leveled the packaging film to ensure that the surface of the final output packaging film is smooth and flat.

[0099] Secondly, the stability is enhanced: the arrangement of the transition piece 6 between each third flattening assembly 5 provides necessary support to prevent the packaging film from sagging or wrinkling between the rollers.

[0100] The combination of multiple rollers and transition pieces makes the packaging film more evenly stressed during the entire leveling process and the transportation more stable.

[0105] In this embodiment, the driving mechanism 4 includes a driving member 41, a first transmission assembly 42 and a second transmission assembly 43. The first transmission assembly 42 is connected to the first belt 21 and the second belt 31, and is responsible for driving the first belt 21 and the second belt 31 to perform circular motion under the drive of the driving member 41. The second transmission assembly 43 is connected to the first roller 51 and the second roller 52, and is responsible for driving each roller to rotate under the drive of the driving member 41.

[0106] One of the first transmission assembly 42 and the second transmission assembly 43 is connected to the output end of the driving member 41 to receive the power output of the driving member 41. The driving member 41 (such as a motor) transmits the power to the first transmission assembly 42 or the second transmission assembly 43 through the output end. The power is further transmitted to the belts or rollers connected to each other through the transmission assembly to make them move, thereby realizing the transportation and flattening of the packaging film.

[0107] The working process of the driving mechanism 4 of the present application scheme is as follows:

[0108] Power start: The driving member 41 starts and outputs power to the connected transmission assembly (assuming it is the first transmission assembly 42). The first transmission assembly 42 transmits power to the first belt 21 and the second belt 31, causing them to start circular motion.

[0109] Belt drive: The first belt 21 and the second belt 31 are driven by the first transmission component 42 to perform a circular motion to clamp and transport the packaging film. Driven by the belts, the packaging film passes through the first flattening component 2 and the second flattening component 3 to be preliminarily flattened.

[0110] Roller transmission: The first transmission assembly 42 transmits part of the power to the second transmission assembly 43 through a transmission connection. The second transmission assembly 43 drives the first roller 51 and the second roller 52 to rotate, further flattening the packaging film.

[0111] The plurality of third leveling components 5 are driven by the second transmission component 43 to level the packaging film multiple times in sequence.

[0112] The present application achieves the following effects by setting the driving mechanism 4 of the above structure:

[0113] The driving mechanism 4 realizes continuous automatic flattening of the packaging film by coordinating the movements of the transmission components. The power transmission is accurate and efficient, ensuring the flattening effect of the packaging film during the entire transmission process.

[0114] The driving mechanism 4 ensures the synchronous movement of the first belt 21, the second belt 31 and the roller, and the packaging film is evenly stressed during the conveying process, reducing shaking and deviation. Under the action of multiple leveling components, the surface of the packaging film is more flat and smooth.

[0118] In this embodiment, the first transmission assembly 42 includes a driving gear 421 and a first driven gear 422, which are meshed with each other, and the two transmission assemblies are arranged on the same side of the support 1. One end of the first rotating shaft 22 adjacent to the third leveling assembly 5 passes through the side wall of the support 1 and is connected to the driving gear 421, and the other end is connected to the output end of the driving member 41. One end of the second rotating shaft 32 adjacent to the third leveling assembly 5 passes through the side wall of the support 1 and is connected to the first driven gear 422, and the other end is rotatably connected to the support 1.

The driving gear 421 drives the first driven gear 422 to rotate through meshing transmission. The rotation of the first driven gear 422 further drives the second rotating shaft 32 to move, thereby driving the second belt 31 to move.

[0119] The driving member 41 is started, and transmits power to the driving gear 421 through the output end. The driving gear 421 rotates, and drives the first driven gear 422 to rotate synchronously through meshing.

[0123] The packaging film is clamped by the first belt 21 and the second belt 31 and is gradually flattened by the flattening assembly. Each time the packaging film passes through a third flattening assembly 5, the upper and lower surfaces of the packaging film are squeezed by the first roller 51 and the second roller 52, respectively, to make the surface more flat and smooth.

[0124] The present application achieves the following effects by setting the first transmission assembly 42 of the above structure:

[0125] Firstly, the design of the first transmission assembly 42 ensures the synchronous movement of the first belt 21 and the second belt 31, so that the packaging film is evenly stressed during the conveying process, and the leveling effect is more ideal.

[0126] After multiple extrusions and transmissions by the leveling components, the surface of the packaging film is made smooth and wrinkle-free, thus improving product quality.

[0127] Secondly, the meshing transmission between the driving gear 421 and the first driven gear 422 provides reliable power transmission, ensuring a stable and jitter-free transmission process.

[0128] The packaging film is always evenly clamped and squeezed during the transmission process, the conveying process is smooth, and deviation and irregular movement are reduced.

[0129] Thirdly, by adjusting the meshing distance between the driving gear 421 and the first driven gear 422 , packaging films of different thicknesses and materials can be adapted.

[0131] Fourthly, the first transmission assembly 42 has a simple structure, and the gear meshing design is easy to disassemble and maintain, thereby reducing the downtime and maintenance cost of the production line.
