Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and more specifically, to a bagging device for roll paper packaging. Background Technology

[0002] As an everyday necessity, toilet paper requires strict quality control during production and packaging to ensure product quality. During packaging, plastic film bags or composite material bags are typically used to protect the toilet paper from external environmental influences. However, in practice, it's not always easy to determine whether a packaging bag is properly sealed, especially for bags that may have minor leaks, which are often difficult to detect.

[0003] If toilet paper gets damp, it will not only affect the user experience but also shorten its shelf life. In a humid environment, damp toilet paper is prone to bacterial growth and even mold, posing a potential threat to consumers' health. Summary of the Invention

[0004] This invention proposes a bagging device for roll paper packaging, which solves the problem in related technologies that damaged packaging bags can easily affect the storage of roll paper, easily breed bacteria, and shorten its shelf life.

[0005] The technical solution of the present invention is as follows: A bagging device for roll paper packaging, comprising: The support platform has an air cavity, which has a first air hole and a second air hole; A detection plate, which is movably mounted on the support platform, is used to contact the upper part of the packaging bag; The air injection component is used to inject air into the packaging bag, causing the packaging bag to expand. After the packaging bag expands, it contacts the detection plate and drives the detection plate to move. The first sealing element is disposed on the detection plate and is used to seal the first vent or to unseal the first vent after moving with the detection plate. The second sealing element is movable and disposed within the second vent. After the second sealing element is moved, it seals or unseales the second vent.

[0006] Optionally, it also includes: The machine tool, wherein the support platform is mounted on the machine tool. A first clamping member is disposed on the machine tool and located on one side of the bearing platform. The first clamping member has an air injection hole that communicates with the air chamber. The second clamping member is raised and lowered on the machine tool, located on one side of the bearing platform; The air-injecting component is movably mounted on the second clamp. After the air-injecting component moves, it inserts into or cancels the opening of the packaging bag to inject air into the packaging bag to be filled with roll paper. After the second clamp rises and falls, it abuts against the first clamp to clamp or move away from the opening of the packaging bag on the side of the air-injecting component.

[0007] Optionally, the first clamp has a first clamping portion and a first semi-circular groove, and the second clamp has a second clamping portion and a second semi-circular groove. After the second clamp abuts against the first clamp, the first semi-circular groove and the second semi-circular groove form a mounting groove. After the air injection component moves, its outlet end enters the mounting groove. The diameter of the outlet end is the same as the diameter of the mounting groove. The device further includes: A sealing gasket is disposed on the groove wall of the first semicircular groove, the groove wall of the second semicircular groove, the first clamp, and the second clamp.

[0008] Optionally, both the first clamp and the second clamp have adsorption ports for adsorbing or removing the adsorption of the upper and lower sides of the packaging bag opening.

[0009] Optionally, the second sealing element is a digital check valve, and further includes: A swinging component is oscillatingly disposed on the support platform, located between the first clamp and the support platform, and below the packaging bag; A driving device is disposed on the support platform and electrically connected to the second sealing member. After the second sealing member unblocks the second air hole, the driving device drives the swinging member to swing, and the swinging member moves the packaging bag away from the support platform.

[0010] Optionally, the second clamp has a guide groove having a horizontal section and an inclined section that are interconnected, the air injection element being movably disposed within the guide groove, and the upper part of the inclined section being located above the horizontal section.

[0011] Optionally, the gas injection component has a connecting portion, the connecting portion having a connecting groove, and further includes: A connecting block, which is movably disposed within the connecting groove; A movable component, which is movably mounted on the second clamping component, and a connecting block is mounted on the movable component; A linear drive element is disposed on the second clamping member to drive the moving member to move.

[0012] Optionally, the first clamp and the second clamp have a feeding space, and further include: A feeding table, which is V-shaped, is movably mounted on the first clamp and located within the feeding space. The feeding table is used to transport rolls of paper. A pusher component is movably mounted on the machine tool, located above the feeding table. After the pusher component moves, it pushes the roll of paper through the feeding table into the packaging bag.

[0013] Optionally, it also includes: The extrusion component, comprising two components, is movably disposed on both sides of the support platform, and the extrusion components move closer to or further away from each other after being moved. A conveyor belt is circulated and moved on the machine tool, located in the middle of the support platform, with the upper surface of the conveyor belt flush with the upper surface of the support platform.

[0014] Optionally, it also includes: A rotation drive component is mounted on the support platform. The screw has a positive thread and a negative thread, and the two extrusion members are respectively threaded onto the positive thread and the negative thread.

[0015] The working principle and beneficial effects of this invention are as follows: In this invention, the packaging bag refers to a type with a single-sided seal and a single-sided opening. Before inserting the roll of paper, a damage inspection is required to ensure there is no damage, thus providing reliable assurance for the subsequent packaging process. Before packaging, an air injection device is first inserted into the opening of the packaging bag to inject air. The outlet of the air injection device can be smaller than the size of the opening of the packaging bag. Simultaneously, the opening on the side of the air injection device needs to be sealed. The purpose is to inflate the packaging bag after inflation. The outlet of the air injection device can also be adapted to the size of the opening of the packaging bag to support the opening, ensuring smooth inflation of the packaging bag. The detection plate is located above the packaging bag. Preferably, the minimum height of the detection plate can be set to be about 10mm lower than the normal inflated height of the packaging bag (considering error). In actual production, this can be adjusted according to different packaging bags and different rolls of paper. The purpose is that when the packaging bag inflates and its volume increases, it can touch the lower part of the detection plate and push the detection plate upward. The first sealing element is set on the detection plate and moves synchronously with the detection plate. When the detection plate rises, the first sealing element also rises and cancels the sealing of the first vent.

[0016] Working principle: The packaging bag is inflated using an inflation device, while an inflation pipeline (not mentioned above, but can be separately routed in actual use) simultaneously inflates the air chamber. When the inflation pipeline reaches a certain level, the second sealing device releases the seal on the second air hole. The second sealing device can be a one-way valve, etc. It is worth noting that the time required for the inflation pipeline to inflate the air chamber and raise the air pressure to the level required for the second sealing device to release the seal on the second air hole is longer than the time required for the inflation device to inflate the packaging bag. This allows the packaging bag to expand. The time it takes for the lower part of the detection plate to touch and lift the detection plate upwards can be set according to the actual production equipment. For reference, it is about 2 seconds. That is, if the packaging bag fails to expand to lift the detection plate within a certain time while ensuring the gas injection speed, the gas injection pipeline will continuously pressurize the gas chamber during this process. Since the detection plate is not lifted, the first sealing component will continue to block the first air hole. After 2 seconds, the pressure in the gas chamber will reach a certain value, which will cause the second sealing component to move under the action of air pressure, canceling the blockage of the second air hole, which means that there is air leakage in the packaging bag.

[0017] When the packaging bag inflates to a certain height within the standard time, causing the detection plate to move, the first sealing element moves accordingly. Since the air chamber only reaches the pressure value required to open the second sealing element after 2 seconds, the second sealing element continues to block the second air hole. After the first sealing element moves, the first air hole opens, releasing the gas in the air chamber, indicating that the packaging bag has no obvious damage. This detection system can quickly and accurately determine whether there are minor leaks in the packaging bag, reducing the impact of the external environment on the packaged paper rolls during transportation and storage, and helping to improve the quality control level of paper roll packaging.

[0021] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0023] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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 communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] 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.

[0025] Reference Figures 1-6A bagging device for roll paper packaging is proposed, comprising: a support platform 1 having an air chamber 101, the air chamber 101 having a first air hole 102 and a second air hole 103; a detection plate 2, which is movably disposed on the support platform 1 and is used to contact the upper part of the packaging bag; an air injection component 3, which is used to inject air into the packaging bag, causing the packaging bag to expand, and after the packaging bag expands, it contacts the detection plate 2 and drives the detection plate 2 to move; a first sealing component 4, which is disposed on the detection plate 2 and is used to seal the first air hole 102 or to unseal the first air hole 102 after moving with the detection plate 2; and a second sealing component 5, which is movably disposed within the second air hole 103 and, after moving, seals or unseals the second air hole 103.

[0026] In this embodiment, the packaging bag refers to a type with one-sided sealing and one-sided opening. Before the roll of paper is put in, a damage test is required to ensure that there is no damage, thereby providing a reliable guarantee for the subsequent packaging process.

[0027] Before packaging, the air infuser 3 is inserted into the opening of the packaging bag to inflate it. The outlet of the air infuser 3 can be smaller than the opening of the packaging bag. At the same time, the opening on the side of the air infuser 3 needs to be sealed. The purpose is to inflate the packaging bag after it is inflated. The outlet of the air infuser 3 can also be matched with the size of the opening of the packaging bag to support the opening of the packaging bag. The purpose is to ensure that air can be smoothly injected into the packaging bag.

[0028] The detection plate 2 is located above the packaging bag. Preferably, the minimum height of the detection plate 2 can be set to be about 10mm lower than the normal height of the expanded packaging bag (taking into account the error). In actual production, it can be set according to different packaging bags and different rolls of paper. The purpose is that after the packaging bag expands and its volume increases, it can touch the lower part of the detection plate 2 and push the detection plate 2 upward.

[0029] The first sealing element 4 is set on the detection plate 2 and moves synchronously with the detection plate 2. When the detection plate 2 rises, the first sealing element 4 will also rise and unblock the first vent 102.

[0030] Working principle: The packaging bag is inflated using the air injection component 3, and simultaneously inflated using the air injection pipeline (not mentioned above, but can be led out separately in actual use) into the air chamber 101. When the air volume injected into the air chamber 101 reaches a certain level, the second sealing component 5 will unseal the second air hole 103. The second sealing component 5 can be a one-way valve, etc. It is worth noting that the time required for the air injection pipeline to inflate the air chamber 101 and for the air pressure inside the air chamber 101 to reach the value that would cause the second sealing component 5 to unseal the second air hole 103 is longer than the time required for the air injection component 3 to inflate the packaging bag, causing the packaging bag to expand. The time it takes for the expansion to touch the lower part of the detection plate 2 and push the detection plate 2 upward can be set according to the actual production equipment. For reference, it is about 2 seconds. That is, if the packaging bag fails to expand to push the detection plate 2 within a certain time while ensuring the air injection speed, the air injection pipeline will continuously pressurize the air chamber 101 during this process. Since the detection plate 2 is not pushed up, the first sealing member 4 will continue to block the first air hole 102. After 2 seconds, the air chamber 101 will reach a certain pressure value, which will cause the second sealing member 5 to move under the action of air pressure, canceling the blockage of the second air hole 103, which means that there is air leakage in the packaging bag.

[0031] When the packaging bag expands to a certain height within the standard time and moves the detection plate 2, the first sealing component 4 moves accordingly. Since the air chamber 101 will only reach the pressure value for the second sealing component 5 to open after 2 seconds, the second sealing component 5 continues to block the second air hole 103. After the first sealing component 4 moves, the first air hole 102 opens and releases the gas in the air chamber 101, which means that the packaging bag is not obviously damaged.

[0032] This detection system can quickly and accurately determine whether there are minor defects in the packaging bag, reducing the impact of the external environment on the packaged paper rolls during transportation and storage, and helping to improve the quality control level of paper roll packaging.

[0033] Furthermore, it also includes: a machine tool 6, a support platform 1 mounted on the machine tool 6, a first clamp 7 mounted on the machine tool 6 and located on one side of the support platform 1, the first clamp 7 having an air injection hole 701 communicating with an air chamber 101; a second clamp 8, the second clamp 8 being flexibly mounted on the machine tool 6 and located on one side of the support platform 1; an air injection component 3 being movably mounted on the second clamp 8, the air injection component 3 being inserted into or removed from the opening of the packaging bag after being moved, for injecting air into the packaging bag to be filled with roll paper, the second clamp 8 being raised and lowered and abutting against the first clamp 7, for clamping or moving away from the opening of the packaging bag on the side of the air injection component 3; the first clamp 702 and the second clamp 801 both having an adsorption port 9, for adsorbing or removing the adsorption of the upper and lower sides of the opening of the packaging bag.

[0034] In this embodiment, the air injection hole 701 of the first clamp 7 is the air injection passage mentioned above. The air injection hole 701 is connected to the air cavity 101 inside the support platform 1 and is used to provide gas to the air cavity 101.

[0035] To improve the convenience and accuracy of inserting the gas injection component 3 into the opening of the packaging bag, preferably, the outlet end of the gas injection component 3 should be smaller than the opening size of the packaging bag. The first clamp 7 and the second clamp 8 are used to clamp the opening of the packaging bag on the side of the gas injection component 3, thereby achieving a sealing effect and improving the gas injection effect.

[0036] The second clamping member 8 is jacked up and mounted on the machine tool 6, located on the same side of the machine tool 6 as the first clamping member 7. The second clamping member 8 is positioned above the first clamping member 7. Preferably, the upper surface of the first clamping member 7 is equal to or slightly lower than the upper surface of the support platform 1, so that after the packaging bag is moved, its opening can more easily enter the upper part of the first clamping member 7. The second clamp 8 moves downward and together with the first clamp 7 clamps the opening of the packaging bag. At this time, the first clamp 7 and the second clamp 8 respectively suck up the upper and lower sides of the opening of the packaging bag through the suction port 9. After sucking, the second clamp 8 is controlled to rise and open the opening of the packaging bag. The air injection component 3 is moved so that it is inserted into the opening of the packaging bag. The second clamp 8 is further controlled to descend and clamp the opening of the packaging bag around the air injection component 3 and on the side to form a sealed state.

[0037] This method ensures that the opening of the packaging bag is firmly clamped and sealed during the inflation process, preventing gas leakage and guaranteeing the efficiency and accuracy of inflation. Simultaneously, this design improves the automation and reliability of the entire inspection process, reducing human error and uncertainty. This provides strong assurance for the packaging quality of roll paper.

[0038] Furthermore, the first clamp 7 has a first clamping portion 702 and a first semi-circular groove 703, and the second clamp 8 has a second clamping portion 801 and a second semi-circular groove 802. After the second clamp 8 abuts against the first clamp 7, the first semi-circular groove 703 and the second semi-circular groove 802 form a mounting groove. After the air injection component 3 moves, its air outlet end enters the mounting groove, and the diameter of the air outlet end is the same as the diameter of the mounting groove. It also includes: A sealing gasket is disposed on the groove wall of the first semicircular groove 703, the groove wall of the second semicircular groove 802, the first clamping part 702, and the second clamping part 801.

[0039] In this embodiment, preferably, the end faces of the first clamp 702 and the second clamp 801 are flat to reduce potential damage to the packaging bag during clamping. The first semi-circular groove 703 and the second semi-circular groove 802 combine to form an installation groove, with the diameter of the air outlet end being the same as the diameter of the installation groove. To improve the sealing effect, a sealing gasket is provided. The sealing gasket is flexible. When the second clamp 8 abuts against the first clamp 7, the sealing gasket is squeezed between the groove walls of the first semi-circular groove 703 and the second semi-circular groove 802, and between the first clamp 702 and the second clamp 801. As the pressure between the second clamp 8 and the first clamp 7 increases, the sealing gasket is compressed, thereby filling the tiny gaps between the components and greatly improving the sealing performance. This design effectively prevents gas leakage from the gap between the injection component 3 and the installation groove during the injection process, ensuring that the packaging bag can be quickly and accurately filled with gas, providing a reliable guarantee for subsequent packaging bag damage detection.

[0040] Furthermore, the second sealing component 5 is a digital one-way valve, and also includes: a swing component 10, which is swing-mounted on the support platform 1, located between the first clamp 7 and the support platform 1, and below the packaging bag; and a driving device 11, which is mounted on the support platform 1 and electrically connected to the second sealing component 5. After the second sealing component 5 unblocks the second air hole 103, the driving device 11 drives the swing component 10 to swing, and after the swing component 10 swings, it pushes the packaging bag away from the support platform 1.

[0041] In this embodiment, the purpose of setting up a digital check valve is to display and transmit the check valve status signal. The digital check valve can be a check valve with data display function or a check valve equipped with any of the following devices: pressure tester, flow tester, leakage tester, etc. The purpose is to monitor the working status of the check valve in real time and accurately transmit the status of the check valve to the drive device 11. When the second sealing member 5 unblocks the second vent 103, the drive device 11 will drive the swing member 10 to swing. The drive device 11 can be a drive motor. The specific wiring settings can be set according to the actual production line space and the selected check valve model. This is information that can be obtained by those skilled in the art and will not be described in detail here.

[0042] The swing member 10 is located between the first clamp 7 and the support platform 1. The packaging platform passes sequentially over the support platform 1, the upper part of the swing member 10, and enters between the first clamp 7 and the second clamp 8. Therefore, preferably, the upper surface of the swing member 10 is flush with the upper surface of the support platform 1 to ensure smooth movement of the packaging bag. When the packaging bag is damaged and leaking air, the second clamp 8 rises away from the first clamp 7, releasing the clamp on the opening of the packaging bag. The air injection member 3 moves away from the packaging bag, and the driving device 11 drives the swing member 10 to swing. After the swing member 10 swings, it moves the packaging bag below the swing member 10 for further processing. (Refer to...) Figure 3It can be seen that the swinging component 10 will not interfere with the first clamping component 7 during the swinging process.

[0043] Furthermore, the second clamp 8 has a guide groove 803, which has a horizontal section 804 and an inclined section 805 that are interconnected. The air injection component 3 is movably disposed within the guide groove 803, and the upper part of the inclined section 805 is located above the horizontal section 804. The air injection component 3 has a connecting part 301, which has a connecting groove, and also includes: a connecting block 12, which is movably disposed within the connecting groove; a moving component 13, which is movably disposed on the second clamp 8, and the connecting block 12 is disposed on the moving component 13; and a linear drive component 14, which is disposed on the second clamp 8 and drives the moving component 13 to move.

[0044] In this embodiment, the second clamp 8 is equipped with a guide groove 803, which consists of a horizontal section 804 and an inclined section 805, which are interconnected. The air injection component 3 can move within the guide groove 803, wherein the upper part of the inclined section 805 is higher than the horizontal section 804. The guide groove 803 allows the air injection component 3 to move smoothly along a predetermined path. The air injection component 3 itself has a connecting part 301, and a connecting groove is provided inside the connecting part 301. The connecting groove is used to accommodate the connecting block 12 that can move along it. This structure allows the air injection component 3 to achieve a certain degree of expansion and contraction during movement, thereby better adapting to different working conditions. The connecting block 12 is disposed in the connecting groove and connected to the moving component 13. When the moving component 13 moves under the action of the linear drive component 14, it will drive the connecting block 12 to move together. In order to ensure a stable connection between the connecting block 12 and the connecting groove, an elastic buckle can be provided on the connecting block 12, and an elastic slot can be provided at a corresponding position inside the connecting groove, thereby ensuring a good contact state even during movement. The movable component 13 is mounted on the second clamp 8 and can be driven by the linear drive component 14. When the linear drive component 14 is activated, it causes the movable component 13 to move in a set direction, thereby indirectly displacing the air injection component 3 through the connecting block 12.

[0045] When the linear drive 14 is activated and drives the moving part 13 to move, the moving part 13 causes the connecting block 12 to move horizontally along the connecting groove. Due to the connection between the connecting block 12 and the air injection part 3, the air injection part 3 also moves. The air injection part 3 first moves along the inclined section 805 of the guide groove 803, then enters the horizontal section 804, and finally reaches the position of the second semicircular groove 802. Furthermore, the second clamp 8 descends, causing the second semicircular groove 802 to mate with the first semicircular groove 703, together forming a complete mounting groove to cover the air injection end of the air injection part 3, thereby ensuring a good sealing effect.

[0046] By positioning the air-injecting component 3 closer to the upper part of the second clamp 8 and further away from the first clamp 702, sufficient space is reserved between the first semicircular groove 703 and the second semicircular groove 802, facilitating the conveying of materials such as rolled paper. This not only ensures sealing during the air injection process but also effectively utilizes space, improving the efficiency and practicality of the entire system.

[0047] Furthermore, the first clamp 7 and the second clamp 8 have a feeding space 15, and also include: a feeding table 16, which is V-shaped and is movably disposed on the first clamp 7, located within the feeding space 15, and the feeding table 16 is used to transport the roll paper; and a pusher 17, which is movably disposed on the machine tool 6, located above the feeding table 16, and after the pusher 17 moves, it pushes the roll paper through the feeding table 16 into the packaging bag.

[0048] In this embodiment, a feeding space 15 is formed between the first clamp 7 and the second clamp 8 for conveying the paper roll. The feeding table 16 is designed in a V-shape, which helps the paper roll stay centered during the conveying process, ensuring that the paper roll can enter the packaging bag more accurately. The V-shaped design not only facilitates the positioning of the paper roll, but also reduces the possibility of the paper roll deviating from the center during the conveying process, thus improving the overall working accuracy.

[0049] The feeding table 16 is movably mounted on the first clamp 7. When the air injection unit 3 injects air, the feeding table 16 lowers to make room. When it needs to carry the transport roll of paper, the feeding table 16 rises. The pusher 17 is located above the feeding table 16 and is movably mounted on the machine tool 6. When the roll of paper needs to be fed into the packaging bag, the pusher 17 is driven to move, thereby pushing the roll of paper along the feeding table 16 until it falls into the packaging bag. By using the V-shaped feeding table 16 and the pusher 17, the system can efficiently and accurately complete the roll paper conveying and packaging process. The V-shaped design ensures that the roll of paper is always centered, reducing the risk of deviation, while the pusher 17 ensures that the roll of paper can smoothly enter the packaging bag, improving the efficiency and reliability of the entire packaging process.

[0050] Furthermore, it also includes: extrusion parts 18, two of which are movable and disposed on both sides of the support platform 1, and the extrusion parts 18 move closer to or further away from each other after moving; a conveyor belt 19, which is circulated and disposed on the machine tool 6, located in the middle of the support platform 1, and the upper surface of the conveyor belt 19 is flush with the upper surface of the support platform 1; a rotation drive 20, which is disposed on the support platform 1, and a positive and negative screw 21, which has a positive thread and a negative thread, and the two extrusion parts 18 are respectively threaded to the positive thread and the negative thread.

[0051] In this embodiment, there are two extruders 18, which are respectively movably disposed on both sides of the support platform 1. When the roll of paper needs to be processed, the drive unit 20 drives the forward and reverse screws 21 to rotate, causing the two extruders 18 to move in opposite directions, i.e., closer to or further apart. When they move closer, they extrude pressure on the circumferential sides of the roll of paper, flattening it to facilitate the subsequent packaging process. Once the roll of paper is loaded into a packaging bag, the extruders 18 separate again and return to their original positions. The conveyor belt 19 rotates in the opposite direction, moving the packaging bag containing the roll of paper to the next process. By using the extruder 18 to circumferentially compress the paper roll, it can be flattened, making it easier to pack into a packaging bag. The design of the conveyor belt 19 ensures smooth movement of the packaging bag and the packaging bag containing the paper roll, improving the efficiency of the entire packaging process. In addition, the combined use of the positive and negative screws 21 and the rotary drive 20 makes the movement of the extruder 18 more precise and controllable, ensuring the accuracy and reliability of the paper roll processing.

[0052] It should be noted that the height of the positive and negative lead screws and the height of the detection plate 2 should be higher than the overall height of the packaging bag after the roll of paper is packed. As a preferred option, in order to improve the stability of the roll of paper during transportation, this solution adopts the method of transporting the roll of paper lying flat (i.e., the axis is parallel to the ground).
