Description

Technical Field

[0001] This invention relates to the field of automatic packaging technology, and more specifically to a fully automatic paper packaging device. Background Technology

[0002] Paper is made from raw materials containing plant fibers through processes such as pulping, conditioning, papermaking, and processing. Paper is a medium for writing and printing, and can also be used for packaging, hygiene, and other purposes. Thanks to the invention and popularization of paper, people no longer need to use materials such as mud, stone, wood, pottery, and metal to record text or pictures, which has enabled the dissemination and preservation of a large amount of information from ancient times. After the paper is produced, it is often packaged in stacks using packaging devices to facilitate transportation and sales.

[0003] For example, patent CN108438974B, published on March 22, 2024, discloses a paper liner stacking and packaging machine, which includes a paper feeding mechanism, etc. The paper feeding mechanism is located to the left of the paper cutting mechanism, the paper cutting mechanism is located to the left of the paper dispensing mechanism, the paper dispensing mechanism is located to the left of the gripper moving mechanism, the gripper moving mechanism is located above the conveyor, the conveyor is located on the lifting mechanism, the lifting mechanism is located to the right of the lifting conveyor, the lifting conveyor is located below the equipment cover, the tensioning roller is located between the paper feeding mechanism and the lifting conveyor, the paper pressing rope is located below the air blowing port, and the air blowing port is installed on the paper dispensing mechanism. This patent realizes the automation of stacking and liner stacking, with fast production speed, neat and consistent glass stacking, reduced breakage, fast paper feeding, reduced paper consumption, energy saving and environmental protection. Different lengths of separator paper can be set for different sizes of glass to achieve optimal configuration, improve product yield, reduce labor costs, and reduce the labor intensity of workers.

[0004] When stacks of paper are packaged, the packaging device first puts bags over the stack of paper, and then seals the bags covering the stack of paper. Existing packaging equipment typically uses adhesive or plastic sealing to seal the bags covering the paper. When using adhesive sealing, the surface of the sealing edge of the bag is coated with adhesive, and then an electric pusher mechanism pushes the sealing edge of the bag to adhere it to the surface of the bag, completing the sealing process. However, existing electric pusher mechanisms require a certain gap between the bottom of the pusher and the topmost piece of paper. If the gap is too small, the pusher may easily tear the outer packaging bag or even cause the topmost piece of paper to break. If the gap is too large, the packaging bag will be loosely wrapped around the stack of paper after sealing. During subsequent transportation, the loose packaging can cause the paper to move around, potentially leading to the packaging bag coming undone. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic paper packaging device to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic paper packaging device includes a bagging unit, a sealing unit, and a conveying unit for conveying stacks of paper. The conveying unit conveys stacks of paper sequentially through the bagging unit and the sealing unit. The sealing unit includes a push plate and a telescopic rod, as well as a guide unit and an adjusting seat installed at the end of the telescopic rod. The push plate is vertically slidably mounted on the adjusting seat. During the horizontal extension stroke of the telescopic rod, under the guidance of the guide unit, the push plate moves horizontally and slides vertically on the adjusting seat simultaneously so that the bottom of the push plate adheres to and squeezes the sealing film of the outer packaging bag of the paper to achieve sealing.

[0008] As described above, the adjusting seat has a vertical first slide groove, and the push plate is slidably installed in the first slide groove through the first slider. The first slider is connected to the top wall of the first slide groove by a traction spring.

[0009] The aforementioned guiding unit includes a guiding plate and a guiding groove formed on the guiding plate, and the push plate moves along the groove direction of the guiding groove based on the extension of the telescopic rod.

[0010] As described above, the guide plate is installed on the side of the conveying unit near the sealing unit. The guide plate is set horizontally and extends horizontally away from the sealing unit.

[0011] The aforementioned guide groove includes a horizontal section and an inclined section that slopes toward the surface of the plastic film.

[0012] As mentioned above, a vertical second slide groove is also provided on the side wall of the push plate near the guide plate. A second slider is slidably installed in the second slide groove. The second slider is connected to the bottom wall of the second slide groove by a connecting spring. One end of the second slider is inserted into the guide groove.

[0013] The guide plate is also provided with a reset groove. One end of the reset groove is connected to the end of the inclined section away from the horizontal section, and the other end of the reset groove is connected to the end of the horizontal section away from the inclined section. The reset groove and the guide groove form an annular groove. The reset groove is divided into a first reset section and a second reset section. The first reset section is set horizontally, and the second reset section is set inclined upwards.

[0014] As mentioned above, a one-way deflection mechanism is provided at the connection between the reset groove and the guide groove. The one-way deflection mechanism is used to restrict the second slider that has entered the first reset section from re-entering the inclined section, and to prevent the second slider that has returned to the horizontal section from re-entering the second reset section.

[0015] As mentioned above, a pressure plate is also provided on the surface of the push plate near the sealing film. When the push plate resets along the first reset section, the pressure plate is used to press the sealing film.

[0016] As mentioned above, the top of the pressure plate is fixedly connected to the surface of the push plate, and the bottom surface of the pressure plate is lower than the bottom surface of the push plate.

[0017] The beneficial effects of this invention are as follows: by setting a guide unit, during the horizontal extension stroke of the telescopic rod, the push plate slides vertically on the adjusting seat in sync with the horizontal movement of the push plate under the guidance of the guide unit, so that the bottom of the push plate fits and squeezes the sealing film of the outer packaging bag of the paper to achieve sealing, thereby improving the packaging quality of the paper stack and avoiding the situation of loose paper stack packaging or paper damage.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1-9 The present invention will be described in further detail below.

[0031] This invention provides a fully automatic paper packaging device, including a bagging unit 2, a sealing unit 3, and a conveying unit 1 for conveying stacked paper. The conveying unit 1 conveys the stacked paper sequentially through the bagging unit 2 and the sealing unit 3. The sealing unit 3 includes a push plate 31 and a telescopic rod 32, as well as a guide unit 4 and an adjusting seat 34 installed at the end of the telescopic rod 32. The push plate 31 is vertically slidably installed on the adjusting seat 34. During the horizontal extension stroke of the telescopic rod 32, under the guidance of the guide unit 4, the push plate 31 moves horizontally and slides vertically on the adjusting seat 34 simultaneously so that the bottom of the push plate 31 adheres to and squeezes the sealing film 52 of the outer packaging bag 5 of the paper to achieve sealing.

[0032] Specifically, the conveying unit 1 adopts an existing belt conveyor mechanism. The conveying unit 1 includes a conveying table and vertically arranged side plates on both sides. The conveying table conveys stacks of paper (hereinafter referred to as paper stacks) sequentially through the bagging unit 2 and the sealing unit 3. The bagging unit 2 uses a common bagging machine, which contains a large number of packaging bags 5. Each packaging bag 5 consists of two layers of plastic film 51 arranged vertically. The side of the packaging bag 5 closest to the sealing unit 3 is open, while the two layers of plastic film 51 on the other three sides are closed and connected. Furthermore, the lower layer of plastic film 51 of the packaging bag 5 extends into a sealing film 52 for sealing the opening. An adhesive layer 53 is provided on the upper surface of the sealing film 52. The adhesive layer 53 is used to bend the sealing film 52 to adhere to the upper plastic film 51 during sealing, thereby sealing the plastic film 51. A guide plate 33 is installed on the conveying unit 1 and located between the sealing unit 3 and the bagging unit 2. One end of the guide plate 33 is inclined so that its height gradually increases along the conveying direction of the conveying unit 1. Thus, the sealing film 52 of the packaged bag 5 after bagging is in a horizontal position. As the conveying unit 1 conveys, the sealing film 52 of the packaged bag 5 is guided by the inclined section 422 of the guide plate 33, and the sealing film 52 of the packaged bag 5 gradually changes from a horizontal position to an upward vertical position (this is prior art and will not be described in detail), which facilitates the sealing by the push plate 31.

[0033] When paper stacks need to be packaged, they are placed on conveyor unit 1, which transports them into bagging unit 2. Bagging unit 2 then bags the paper stack, leaving it wrapped in a packaging bag 5. At this point, the packaging bag 5 is open on the side closest to sealing unit 3, and its sealing film 52 is horizontal. As conveyor unit 1 continues to transport the paper stack, the packaging bag 5 passes through guide ramp 33, which guides the sealing film 52 of the packaging bag 5. When the packaging bag 5 moves to the front of the push plate 31, the sealing film 52 is vertically arranged in front of the push plate 31. Then the conveying unit 1 pauses, the telescopic rod 32 extends, and the telescopic rod 32 moves synchronously with the push plate 31. The push plate 31 pushes the sealing film 52 to press it onto the upper plastic film 51 so that the adhesive layer 53 is bonded to the surface of the upper plastic film 51, completing the sealing process of the packaging bag 5. Then, the conveying unit 1 continues to work, conveying the packaged packaging bag 5 away from the area of ​​the push plate 31, completing the packaging process of the paper stack.

[0034] Obviously, when packaging paper stacks, the bottom surface of the pusher plate 31 needs to be above the upper plastic film 51 and at a suitable distance from it. If the bottom surface of the pusher plate 31 is below the upper plastic film 51, when the pusher plate 31 pushes the sealing film 52 to seal, the pusher plate 31 will push the sealing film 52 to press against the side wall of the paper stack, causing the paper stack to deform and affecting the packaging quality. If the bottom surface of the pusher plate 31 is above the upper plastic film 51, but the distance between the bottom surface of the pusher plate 31 and the upper plastic film 51 is large, after the pusher plate 31 pushes the sealing film 52 to seal, the sealing film 52 may not be able to adhere to and press against the upper plastic film 51. In this case, the packaging bag 5 wraps the paper stack loosely. During subsequent transportation, the loose packaging is prone to relative movement between the paper stacks, which may cause the packaging bag 5 to fall apart.

[0035] To solve the above problems, an adjustment seat 34 is installed on the telescopic end of the telescopic rod 32, and the push plate 31 is vertically slidably installed on the adjustment seat 34. The conveying unit 1 is provided with a guide unit 4. During the horizontal extension stroke of the telescopic rod 32, under the guidance of the guide unit 4, the push plate 31 moves horizontally and slides vertically on the adjustment seat 34 at the same time so that the bottom of the push plate 31 fits against the sealing film 52 of the outer packaging bag of the paper stack to achieve sealing. The guide unit 4 includes a guide plate 41 and a guide groove 42 opened on the guide plate 41. The push plate 31 moves along the groove direction of the guide groove 42 based on the extension of the telescopic rod 32.

[0036] Specifically, the guide groove 42 includes a horizontal section 421 and an inclined section 422 that slopes towards the surface of the plastic film 51 (in this embodiment, the inclined section 422 slopes downwards). The guide plate 41 is horizontally arranged and extends towards the conveying table. The adjusting seat 34 has a vertical first slide groove 341. The push plate 31 is slidably installed in the first slide groove 341 through the first slider 343. The first slider 343 is connected to the top wall of the first slide groove 341 through the traction spring 342. The push plate 31 also has a vertical second slide groove 311 on the side wall near the guide plate 41. The second slider 313 is slidably installed in the second slide groove 311. The second slider 313 is connected to the bottom wall of the second slide groove 311 through the connecting spring 312. One end of the second slider 313 is inserted into the guide groove 42.

[0037] When the packaging bag 5 needs to be sealed, the pusher plate 31 pushes the sealing film 52 to move and bend towards the plastic film 51. As the telescopic rod 32 extends, the pusher plate 31 slides along the guide groove 42 on the guide plate 41 via the second slider 313. When the second slider 313 slides along the horizontal section 421, the pusher plate 31 pushes the sealing film 52 closer to the upper plastic film 51. When the second slider 313 leaves the horizontal section 421 and enters the inclined section 422 and slides, the pusher plate 31 pushes the sealing film 52 to gradually press against the surface of the upper plastic film 51. When the plastic film 51 is in place, the push plate 31 is blocked by the packaging bag 5 containing the paper stack below. At this time, as the telescopic rod 32 continues to extend, the push plate 31 slides on the first slide groove 341 of the adjusting seat 34. At the same time, the second slider 313 also slides downward along the groove of the second slide groove 311. At this time, the push plate 31 pushes the sealing film 52 to move horizontally along the surface of the upper plastic film 51. When the push plate 31 passes the adhesive layer 53 on the sealing film 52, under the pressure of the push plate 31, the adhesive layer 53 can be more tightly bonded to the upper plastic film 51, improving the sealing effect of the packaging bag 5.

[0038] Obviously, depending on the thickness of the paper stack to be packaged, the timing of the push plate 31 contacting the upper plastic film 51 when the second slider 313 slides along the inclined section 422 of the guide groove 42 is also different. The thicker the paper stack to be packaged, the earlier the push plate 31 will contact the surface of the upper plastic film 51. As a result, the timing of the push plate 31's translation along the surface of the upper plastic film 51 is also different. When the push plate 31 translates on the upper plastic film 51, the adhesive layer 53 is likely to be located behind the movement path of the push plate 31. That is, as the push plate 31 moves, it cannot pass through the adhesive layer 53. Therefore, the push plate 31 cannot squeeze the adhesive layer 53, which can easily lead to the packaging bag 5 not being sealed tightly enough, affecting the packaging quality of the packaging bag 5.

[0039] To address the aforementioned issues, preferably, the guide plate 41 also includes a reset groove 43. One end of the reset groove 43 is connected to the end of the inclined section 422 away from the horizontal section 421, and the other end of the reset groove 43 is connected to the horizontal section 421. The reset groove 43 and the guide groove 42 form an annular groove. The reset groove 43 is divided into a first reset section 431 and a second reset section 432. The first reset section 431 is horizontally positioned, and the second reset section 432 is inclined upwards. When projected vertically from top to bottom, the projection length of the inclined section 422 on the horizontal plane is the same as the length of the first reset section 431, and the projection length of the second reset section 432 on the horizontal plane is also the same as the length of the horizontal section 421. A unidirectional deflector is provided at the connection between the reset groove 43 and the guide groove 42. In this embodiment, the connection between the reset groove 43 and the guide groove 42 specifically refers to the connection position between the inclined section 422 of the guide groove 42 and the first reset section 431, and the connection position between the horizontal section 421 of the guide groove 42 and the second reset section 432. The one-way deflection mechanism 44 is used to restrict the second slider 313 that has entered the first reset section 431 from re-entering the inclined section 422, and the second slider 313 that has returned to the horizontal section 421 from re-entering the second reset section 432. The one-way deflection mechanism 44 can be a combination of a common baffle, a rotating shaft, and a torsion spring. When the torsion spring is in its natural state, one side of the baffle is restricted, and the rotating shaft can only rotate to one side to drive the baffle to flip. The one-way deflection mechanism 44 is prior art, and its principle will not be described in detail.

[0040] Specifically, when the second slider 313 disengages from the inclined section 422 of the guide groove 42 and enters the reset groove 43, the telescopic rod 32 begins to shorten. Under the traction of the telescopic rod 32, the push plate 31 moves synchronously with the telescopic rod 32. Because a one-way deflection mechanism 44 is provided at the connection between the inclined section 422 of the guide groove 42 and the reset groove 43, under the action of the one-way deflection mechanism 44, the second slider 313 cannot re-enter the guide groove 42 and can only move along the reset groove 43. At this time, the second slider 313 moves along the first section of the reset groove 43. The reset section 431 slides. Because the first reset section 431 is horizontally set, under the traction of the second slider 313, the push plate 31 also moves horizontally on the surface of the upper plastic film 51. Since the length of the first reset section 431 in the horizontal direction is the same as the projected length of the inclined section 422 in the horizontal direction, and when the second slider 313 slides on the inclined section 422, the bottom of the push plate 31 gradually approaches and contacts the upper plastic film 51. Therefore, when the second slider 313 moves to a point where the first reset section 431 is away from the inclined section 422, the push plate 31 gradually approaches and contacts the upper plastic film 51. When the second slider 313 returns to its original position at the end of segment 422, the distance the push plate 31 moves on the plastic film 51 is greater than the distance the push plate 31 moves on the plastic film 51 when sealing. Even if the adhesive layer 53 is located behind the movement path of the push plate 31 when sealing the packaging bag 5, it can still ensure that the push plate 31 passes the position of the adhesive layer 53 on the sealing film 52 and squeezes the adhesive layer 53 to ensure the tightness of the packaging bag 5 when sealed and improve the packaging quality of the packaging bag 5. Subsequently, as the telescopic rod 32 continues to pull, the push plate 31 follows the first... The second slider 313 leaves the first reset section 431 and enters the second reset section 432. When the second slider 313 slides along the second reset section 432, the second slider 313 moves upward in the vertical direction. When the second slider 313 moves to the top of the second slide groove 311, the second slider 313 moves upward with the push plate 31. When the second slider 313 enters the horizontal section 421 of the guide groove 42, the position of the push plate 31 in the first slide groove 341 also returns to the initial state, waiting to seal the next packaging bag 5.

[0041] If the second slider 313 needs to move along the reset groove 43, the push plate 31 can pass through the adhesive layer 53 and make the adhesive layer 53 adhere to the surface of the upper plastic film 51 to complete the sealing process of the packaging bag 5. That is, when the second slider 313 enters the first reset section 431, the sealing film 52 and the upper plastic film 51 are not yet bonded together. Therefore, when the second slider 313 slides along the first reset section 431, the push plate 31 will also move synchronously with the second slider 313. At this time, because the bottom surface of the push plate 31 is against the surface of the sealing film 52, when the push plate 31 moves, under the action of friction, the push plate 31 is easy to carry the sealing film 52 synchronously, causing the sealing film 52 to move on the upper plastic film 51, affecting the sealing quality of the packaging bag 5.

[0042] To solve the above problems, a pressure plate 35 is also provided on the surface of the push plate 31 near the sealing membrane 52. The top of the pressure plate 35 is fixedly connected to the surface of the push plate 31, and the bottom surface of the pressure plate 35 is lower than the bottom surface of the push plate 31.

[0043] Specifically, when the telescopic rod 32 begins to extend, the push plate 31 slides along the guide groove 42 on the guide plate 41 via the second slider 313. When the second slider 313 slides along the inclined section 422, the push plate 31, along with the pressing plate 35, pushes the sealing film 52 to gradually press it against the surface of the upper plastic film 51. The bottom of the pressing plate 35 on the push plate 31 first pushes the sealing film 52 into contact with the upper plastic film 51. As the telescopic rod 32 continues to extend, the pressing plate 35 pulls the sealing film 52 on the upper plastic film 51 in a direction away from the opening of the packaging bag 5, until the sealing film 52 is taut, so that the sealing film 52 can tightly wrap the side wall of the paper stack located at the opening of the packaging bag 5. At this time, the bottom surface of the push plate 31 also presses against the surface of the sealing film 52. Subsequently, the telescopic rod 32 begins to shorten. Under the traction of the telescopic rod 32, the push plate 31 slides along the second slider... 313 slides along the reset groove 43 on the guide plate 41. When the second slider 313 slides along the first reset section 431, the push plate 31 moves horizontally on the surface of the sealing film 52. However, because the pressure plate 35 is pressed on the surface of the sealing film 52, the pressure plate 35 does not move at first due to friction. After the push plate 31 moves a certain distance, it pulls the pressure plate 35 to move. When the push plate 31 moves relative to the pressure plate 35, the bottom surface of the push plate 31 translates on the surface of the sealing film 52. During the translation, the adhesive layer 53 on the sealing film 52 is passed, which makes the sealing film 52 bonded to the upper plastic film 51. At this time, under the action of the pressure plate 35, the sealing film 52 will not move due to the movement of the push plate 31. Thus, the sealing film 52 can tightly wrap the paper stack and improve the packaging effect of the paper stack.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
