Description

Technical Field

[0001] This invention relates to the technical field of tissue packaging, specifically a tissue bulk bag packaging machine. Background Technology

[0002] In the tissue paper production industry, it is a common follow-up processing step to combine multiple small tissue paper packs into a large bag. Traditional tissue paper bag packaging machines usually involve pushing multiple rows of tissue paper packs into an already opened packaging bag.

[0003] The common current method of pushing tissue packs involves treating multiple rows of tissue packs as a single unit and simultaneously pushing them towards the bag opening using a flat pusher. However, this flat pusher method has significant drawbacks: when multiple rows of tissue packs simultaneously come into contact with the bag opening, the overall cross-sectional dimensions of the tissue packs cannot effectively shrink, resulting in large-area friction between the tissue packs and the inner wall of the bag opening. This frictional resistance increases significantly, especially when the packaging bag size is small or has tolerances, which can easily cause the tissue packs to get stuck at the bag opening and not be fully pushed to the bottom of the bag, leading to incomplete packaging. Summary of the Invention

[0004] The purpose of this invention is to provide a paper towel large bag packaging machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large tissue bag packaging machine, comprising a feeding mechanism, a pushing mechanism, a bag-supporting mechanism, a bag-releasing mechanism, and a discharging mechanism arranged sequentially along the packaging direction, and further comprising a packaging bag feeding mechanism for conveying packaging bags to the bag-releasing mechanism; the pushing mechanism includes a stacking platform, a transfer pushing component, and a staggered pushing component, wherein the transfer pushing component is used to push the tissue bags conveyed by the feeding mechanism to the stacking platform to form multiple rows of tissue bags on the stacking platform, and the pushing direction of the staggered pushing component is towards the bag-supporting mechanism, for pushing multiple rows of tissue bags into the packaging bags opened by the bag-supporting mechanism; wherein, the staggered pushing component includes an mounting plate capable of moving laterally toward the bag-supporting mechanism and two first pushing plates fixed on the mounting plate, and a second pushing plate capable of vertically staggering and adjusting with the first pushing plates is provided between the two first pushing plates.

[0006] As described above, in the paper towel large bag packaging machine: the first push plate is fixed to the mounting plate by a connecting rod, and the second push plate is driven to move by a telescopic drive unit mounted on the mounting plate, so that the second push plate is vertically offset from the first push plate in the early stage of pushing the material, and is in the same vertical plane as the first push plate in the later stage of pushing the material.

[0007] As described above, the paper towel large bag packaging machine has a connecting frame fixed on the mounting plate, which is driven to move by a push drive component located above the stacking platform and the bag supporting mechanism.

[0008] As described above, in the paper towel large bag packaging machine: a second baffle and a first baffle are respectively installed at the end of the conveying direction of the feeding mechanism and the end of the pushing direction of the transfer and pushing component on the stacking platform.

[0009] The paper towel large bag packaging machine described above: the pushing mechanism further includes a lower blocking component disposed at the bottom of the stacking platform, the lower blocking component including: a sliding receiving frame slidably installed at the bottom of the stacking platform and capable of moving or resetting along the pushing direction of the transfer pushing component, the sliding receiving frame being mounted with a vertical mounting plate; and a stop bar assembly capable of rotating and lifting along the vertical mounting plate.

[0010] The tissue paper bag packaging machine as described above: the baffle assembly includes: a sliding frame slidably mounted on the vertical mounting plate, a baffle rod fixed on the sliding frame, the baffle rod being able to pass through the strip-shaped through groove formed on the stacking platform to form a baffle position on the stacking platform; the movable end of the cylinder mounted on the vertical mounting plate is fixed to the sliding frame.

[0011] The tissue paper bag packaging machine described above includes: a lifting bag storage for storing stacked packaging bags; a bag feeding mechanism for buffering individual packaging bags, the bag feeding mechanism being used to transfer packaging bags to a bag placement mechanism; and a bag gripping mechanism for gripping individual packaging bags from the lifting bag storage and placing them on the bag feeding mechanism.

[0012] The tissue paper bag packaging machine described above further includes a corner heat sealing mechanism placed between the bag supporting mechanism and the bag releasing mechanism. The corner heat sealing mechanism includes a mounting frame and an upper heat sealing unit and a lower heat sealing unit arranged symmetrically on the upper and lower sides. It also includes two corner plates installed on the mounting frame and symmetrically arranged on both sides along the packaging direction. The corner plates are controlled to move by a lateral adjustment unit.

[0013] The tissue paper bag packaging machine described above also includes a bag-blocking mechanism, which is used to block the tail of the packaging bag when the tissue paper bag enters the packaging bag.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the first push plate and the second push plate vertically offset in the initial state, multiple rows of tissue packs are made to enter the packaging bag in a staggered manner with the sides entering first and the middle being pushed later. This makes the frictional resistance between the tissue packs on both sides and the packaging bag wall relatively small when multiple rows of tissue packs enter the packaging bag, thereby effectively reducing the frictional resistance between the tissue packs and the packaging bag wall, making the pushing smoother, ensuring that multiple rows of tissue packs can be pushed into place, and effectively improving the adaptability to packaging bags of different sizes.

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0018] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0019] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0020] Please see Figures 1-3 As a paper towel large bag packaging machine of the present invention, the paper towel large bag packaging machine includes a feeding mechanism 1, a pushing mechanism 2, a bag supporting mechanism 3, a bag placing mechanism 4 and a discharging mechanism 9 arranged sequentially along the packaging direction, and also includes a packaging bag feeding mechanism for conveying the packaging bag to the bag placing mechanism 4. The end of the bag placing mechanism 4 facing the bag supporting mechanism 3 is provided with a bag opening mechanism 10 for opening the packaging bag. The feeding mechanism 1 is used to convey individual paper towel packages one by one to the pushing mechanism 2. After the paper towel packages on the pushing mechanism 2 form multiple rows and columns, they are pushed into the packaging bag opened by the bag supporting mechanism 3, and then sealed and sent out, realizing the automated packaging process of paper towel packages.

[0021] Please see Figures 4-6 The pushing mechanism 2 includes a stacking platform 201, a transfer pushing component 205, and a staggered pushing component 202. The transfer pushing component 205 is used to push the tissue packs conveyed by the feeding mechanism 1 onto the stacking platform 201 to form multiple rows of tissue packs on the stacking platform 201. The pushing direction of the staggered pushing component 202 is towards the bag supporting mechanism 3, and it is used to push the multiple rows of tissue packs into the packaging bag opened by the bag supporting mechanism 3. The staggered pushing component 202 includes a mounting plate 2021 that can move laterally toward the bag supporting mechanism 3 and two first pushing plates 2025 fixed on the mounting plate 2021. A second pushing plate 2027 that can be vertically staggered and adjusted with the first pushing plate 2025 is provided between the two first pushing plates 2025.

[0022] After the material loading volume on the stacking platform 201 reaches the amount of one large package (hereinafter defined as multiple rows of tissue packs), the staggered push component 202 begins to perform the push action. First, the first push plate 2025 abuts against the multiple rows of tissue packs, and the two first push plates 2025 abut against the two rows of tissue packs on the sides respectively. The second push plate 2027, located in the middle, is vertically staggered from the first push plates 2025 and does not abut against the tissue packs. Then, the mounting plate 2021 begins to move, and the first push plates 2025 on both sides... After the two rows of tissue packs on either side of the multi-row tissue packs have moved a certain distance, the second push plate 2027 comes into contact with the remaining tissue packs. Then, it pushes the multi-row tissue packs to continue moving into the packaging bag. When the two rows of tissue packs on either side of the multi-row tissue packs move to the end of the packaging bag, the mounting plate 2021 stops moving. Then, the second push plate 2027 continues to push the tissue packs in the middle row until the second push plate 2027 and the first push plate 2025 are on the same vertical plane to complete the pushing of the multi-row tissue packs.

[0023] In this embodiment, by vertically offsetting the first push plate 2025 and the second push plate 2027 in the initial state, multiple rows of tissue packs enter the packaging bag in a staggered manner, with the sides entering first and the middle pushing later. This results in relatively low frictional resistance between the tissue packs on both sides and the bag wall when the multiple rows of tissue packs enter the packaging bag, thereby effectively reducing the frictional resistance between the tissue packs and the bag wall and making the pushing smoother. This ensures that the multiple rows of tissue packs can be pushed into place, effectively improving the adaptability to packaging bags of different sizes.

[0024] It should be noted that the misalignment distance between the first push plate 2025 and the second push plate 2027 is less than the length of a tissue pack, ensuring that the tissue packs that enter the packaging bag first will not leave the current column.

[0025] Further, please refer to Figure 6 The first push plate 2025 is fixed to the mounting plate 2021 by a connecting rod 2026. The second push plate 2027 is driven to move by a telescopic drive unit 2022 mounted on the mounting plate 2021, so that the second push plate 2027 is vertically offset from the first push plate 2025 in the early stage of pushing material, and is in the same vertical plane as the first push plate 2025 in the later stage of pushing material.

[0026] It should be noted that the "push-in front" process mentioned here refers to the two rows of tissue packs located on both sides of the multi-row tissue packs not being pushed into place, that is, not entering the tail of the packaging bag. The "push-in back" process mentioned here refers to the multi-row tissue packs having completed filling.

[0027] The second push plate 2027 is also fixed with at least one guide rod 2024, which passes through the mounting plate 2021 and is slidably connected to the mounting plate 2021. The telescopic drive unit 2022 includes, but is not limited to, an electric telescopic rod.

[0028] Before the material is pushed, the telescopic drive unit 2022 is in a retracted state, thereby pulling back the second push plate 2027 to ensure that when the first push plate 2025 abuts against the multi-column tissue packs, there is a certain gap between the second push plate 2027 and the multi-column tissue packs. When the two rows of tissue packs located on both sides of the multi-column tissue packs move to the tail of the packaging bag, the telescopic drive unit 2022 extends to drive the second push plate 2027 to move, so that the second push plate 2027 and the first push plate 2025 are on the same vertical plane.

[0029] Further, please refer to Figure 4 and Figure 6 A connecting frame 2023 is fixed on the mounting plate 2021. The connecting frame 2023 is driven to move by a push drive component 203 located above the stacking platform 201 and the bag support mechanism 3.

[0030] The push drive component 203 drives the mounting plate 2021 and the entire assembly mounted on the mounting plate 2021 to move through the connecting frame 2023, thereby realizing the push drive action.

[0031] Please see Figure 5 A second baffle 206 and a first baffle 204 are respectively installed on the stacking platform 201 along the conveying direction end of the feeding mechanism 1 and the pushing direction end of the transfer and pushing component 205. The second baffle 206 is used to block and limit the individual tissue packs conveyed by the feeding mechanism 1 to the edge of the stacking platform 201, so as to prevent the tissue packs from falling from the conveying direction end of the stacking platform 201. The first baffle 204 is used to block the tissue packs pushed by the transfer and pushing component 205 to the pushing direction end of the stacking platform 201, so as to ensure that the tissue packs can be neatly stacked on the stacking platform 201 according to the preset number of columns, and to avoid the tissue packs from shifting or falling during the transfer and pushing process.

[0032] Further, please refer to Figure 5 and Figure 7 The pushing mechanism 2 further includes a lower blocking component 207 disposed at the bottom of the stacking platform 201. The lower blocking component 207 includes a sliding receiving frame 2072 that is slidably installed at the bottom of the stacking platform 201 and can move or reset along the pushing direction of the transfer pushing component 205. A vertical mounting plate 2073 is installed on the sliding receiving frame 2072, and a stop bar component that can rotate and rise along the vertical mounting plate 2073.

[0033] The sliding support frame 2072 is driven to move by the lateral drive unit 2071 installed at the bottom of the stacking platform 201.

[0034] In one exemplary embodiment, the stop assembly includes a sliding frame 2075 slidably mounted on the vertical mounting plate 2073, a stop bar 2074 fixed on the sliding frame 2075, the stop bar 2074 being able to pass through a strip-shaped through slot 2011 formed on the stacking platform 201 to form a stop position on the stacking platform 201; the movable end of a cylinder 2076 mounted on the vertical mounting plate 2073 is fixed to the sliding frame 2075.

[0035] In this embodiment, after the transfer and push component 205 pushes a row of tissue packs, the transfer and push component 205 resets, and the cylinder 2076 drives the baffle rod 2074 to move upward above the stacking platform 201. Subsequently, the lateral drive unit 2071 drives the sliding frame 2075 and the entire assembly mounted on the sliding frame 2075 to move, thereby moving the baffle rod 2074 to abut against the tissue packs, so as to cooperate with the first baffle 204 to limit the tissue packs in the current row. During the process of the next row of tissue packs being pushed by the transfer and push component 205, the cylinder 2076 drives the baffle rod. 2074 moves downward, and then the lateral drive unit 2071 drives the sliding receiving frame 2072 to move one row of tissue packs toward the transfer and push assembly 205. After the next row of tissue packs is in place, the cylinder 2076 drives the stop bar 2074 to move upward again to abut against the next row of tissue packs, thereby preventing the tissue packs that have been pushed into place from shifting due to machine vibration. This ensures that the tissue packs in the subsequent rows form a neat multi-row arrangement with the tissue packs in the previous rows, which can effectively improve the neatness and stability of the placement of multiple rows of tissue packs and provide a flat foundation for the subsequent push into the packaging bag.

[0036] Please see Figure 8 The packaging bag feeding mechanism includes: a lifting bag storage 5 for storing stacked packaging bags; a bag feeding mechanism 6 for buffering individual packaging bags, the bag feeding mechanism 6 being used to transfer packaging bags to a bag placement mechanism 4; and a bag gripping mechanism 8 for gripping individual packaging bags from the lifting bag storage 5 and placing them on the bag feeding mechanism 6.

[0037] The bag gripping mechanism 8 can adopt a vacuum suction cup structure and be driven by a drive source with a combined horizontal and vertical drive function, so that the bag gripping mechanism 8 can move between the lifting bag magazine 5 and the bag feeding mechanism 6 to realize the gripping and transfer of packaging bags.

[0038] Among them, the lifting bag storage 5 can automatically rise and fall according to the bag grabbing mechanism 8, ensuring that the top layer of packaging bags is always at a height that is easy to grab, thus improving the feeding efficiency.

[0039] Please see Figure 9The paper towel large bag packaging machine also includes a corner heat sealing mechanism 7 placed between the bag supporting mechanism 3 and the bag placing mechanism 4. The corner heat sealing mechanism 7 includes: a mounting frame 701 and an upper heat sealing unit 702 and a lower heat sealing unit 703 arranged symmetrically on the upper and lower sides; it also includes two corner plates 704 installed on the mounting frame 701 and symmetrically arranged on both sides along the packaging direction. The corner plates 704 are controlled to move by a horizontal adjustment unit 705.

[0040] When the bag-supporting mechanism 3 moves toward the bag-releasing mechanism 4 to open the packaging bag, the two folding plates 704 move in opposite directions under the action of the lateral adjustment unit 705, thereby eliminating the interference of the folding plates 704 on the movement of the bag-supporting mechanism 3. After multiple rows of tissue packs enter the packaging bag, the two folding plates 704 are reset to fold the opening of the packaging bag. Then, the upper heat-sealing unit 702 and the lower heat-sealing unit 703 are used to seal the packaging bag. After the packaging is completed, the large package of tissues is moved out under the action of the bag-releasing mechanism 4 and the discharge mechanism 9.

[0041] Furthermore, the tissue paper bag packaging machine also includes a bag-blocking mechanism 11, which is used to block the tail of the packaging bag when the tissue paper bag enters the packaging bag, to prevent the packaging bag from moving with the tissue paper bag during the pushing process, and to ensure that the tissue paper bag can enter the packaging bag stably.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
