Description

Technical Field

[0001] The present invention relates to the technical field of automatic packaging, and in particular to a fully automatic paper packaging device. Background Art

[0002] Paper is made from raw materials containing plant fibers through pulping, modulation, papermaking, processing and other processes. Paper is a carrier for writing and printing, and can also be used for other purposes such as packaging and hygiene. Due to the invention and promotion of paper, people no longer need to use mud, stone, wood, pottery, metal and other materials to record text or pictures, so that a large amount of information in ancient times can be disseminated and preserved. After the existing paper is produced and discharged, in order to facilitate transportation and sale, packaging devices are often used to package the stacks of paper.

[0003] For example, a patent with announcement number CN108438974B and announcement date March 22, 2024 discloses a lining paper stacking and baling machine, which includes a paper feeding mechanism, etc. The paper feeding mechanism is located on the left side of the paper cutting mechanism, the paper cutting mechanism is located on the left side of the paper placing mechanism, the paper placing mechanism is located on the left side of the clamping claw moving mechanism, the clamping claw moving mechanism is located above the conveyor, the conveyor is located on the lifting mechanism, the lifting mechanism is located on the right side of the lifting conveyor, the lifting conveyor is located under the equipment guard, 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 placing mechanism; the patent realizes the automation of stacking and lining paper, fast production speed, neat glass stacking, good consistency, reduced breakage problems, fast paper feeding, reduced paper consumption, energy saving and environmental protection, and can set separator paper of different lengths for glass of different sizes to achieve the optimal configuration, improve product yield, reduce labor costs, and reduce labor intensity of workers.

[0004] When stacks of papers are being packed, the packing device first puts bags on the stacks of papers, and then seals the bags put on the outside of the stacks of papers. Existing packing equipment usually uses gluing or plastic sealing to seal the packaging bags wrapped outside the papers. When gluing is used for sealing, the surface of the sealing edge of the packaging bag is coated with glue, and then the sealing edge on the packaging bag is pushed by an electric push plate mechanism so that the sealing edge adheres to the surface of the packaging bag to complete the sealing of the packaging bag. However, when the existing electric push plate mechanism is working, there needs to be a certain distance between the bottom surface of the push plate and the paper located at the top. If the distance is small, the push plate is easy to push the packaging bag outside the paper to break or even cause the paper located at the top to break. If the distance is large, the glue may only be partially adhered. After the packaging bag is closed, the packaging bag wraps the stacks of papers relatively loosely. In the subsequent transportation process, the loose packaging is easy to cause the papers to move relative to each other, which can easily cause the packaging bag to spread out. Summary of the invention

[0005] The purpose of the present invention is to provide a fully automatic paper packaging device to solve the above-mentioned deficiencies in the prior art.

The first reset section is horizontally arranged, and the second reset section is inclined upward.

[0014] As mentioned above, the connection between the reset groove and the guide groove is provided with a one-way deflection mechanism, which is used to restrict the second slider entering the first reset section from re-entering the inclined section, and the second slider returning to the horizontal section from re-entering the second reset section.

[0015] As mentioned above, the plate surface of the push plate close to the closing film is also provided with a material pressing soft plate, and when the push plate is reset along the first reset section, the material pressing soft plate is used to press the closing film.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1-9 , the present invention is further introduced in detail.

[0031] An embodiment of the present 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 papers. The conveying unit 1 conveys the stacked papers through the bagging unit 2 and the sealing unit 3 in sequence. The sealing unit 3 includes a push plate 31 and a telescopic rod 32, and also includes a guide unit 4 and an adjustment seat 34 installed at the end of the telescopic rod 32. The push plate 31 is vertically slidably installed on the adjustment 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 simultaneously slides vertically on the adjustment seat 34 so that the bottom of the push plate 31 fits and squeezes the closing film 52 of the paper outer packaging bag 5 to achieve sealing.

[0032] Specifically, the conveying unit 1 adopts an existing belt conveying mechanism, and the conveying unit 1 includes a conveying table and side panels vertically arranged on both sides. The conveying table conveys the stacked papers (hereinafter referred to as paper stacks) so that they pass through the bagging unit 2 and the sealing unit 3 in sequence, wherein the bagging unit 2 uses a common bagging machine, and a large number of packaging bags 5 are prepared in the bagging machine. The packaging bag 5 is composed of two layers of plastic film 51 arranged up and down, and the side of the packaging bag 5 close to the sealing unit 3 is open, and the two layers of plastic film 51 on the other three sides are all closed and connected, and the plastic film 51 on the lower layer of the packaging bag 5 extends a section of a closing film 52 for closing the opening, and an adhesive layer 53 is arranged on the upper surface of the closing film 52. The adhesive layer 53 is used to bend the closing film 52 during sealing so as to adhere to the upper plastic film 51, thereby achieving the sealing of the plastic film 51; wherein, a guiding inclined plate 33 is installed on the conveying unit 1 and is located between the sealing unit 3 and the bagging unit 2, and one end of the guiding inclined plate 33 is inclined so that its height gradually increases along the conveying direction of the conveying unit 1, so that the closing film 52 of the packaging bag 5 that has completed the bagging process is in a horizontal position, and as the conveying unit 1 is conveyed, the closing film 52 of the packaging bag 5 is guided by the inclined end of the guiding inclined plate 33, and the closing film 52 of the packaging bag 5 is gradually transformed from a horizontal position to an upwardly erected vertical position (this is a prior art and will not be described in detail), so that the push plate 31 is convenient for sealing.

[0033] When the paper stack needs to be packaged, the paper stack is placed on the conveying unit 1, the conveying unit 1 conveys the paper stack, the paper stack enters the bagging unit 2, the bagging unit 2 bags the paper stack, and the paper stack coming out of the bagging unit 2 is wrapped with a packaging bag 5. At this time, the side of the packaging bag 5 close to the sealing unit 3 is open, and the sealing film 52 of the packaging bag 5 is placed horizontally. As the conveying unit 1 continues to convey, the packaging bag 5 containing the paper stack passes through the guiding inclined plate 33, the guiding inclined plate 33 guides the sealing film 52 of the packaging bag 5, and the sealing film 52 of the packaging bag 5 is sealed by the sealing unit 3. The horizontal placement state is transformed into the standing state. When the packaging bag 5 moves to the front of the push plate 31, the closing film 52 is vertically arranged in front of the push plate 31. Then the conveying unit 1 is temporarily stopped, the telescopic rod 32 is extended, and the telescopic rod 32 moves synchronously with the push plate 31. The push plate 31 pushes the closing film 52 to press on the upper plastic film 51 so that the adhesive layer 53 adheres 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 to leave the area of ​​the push plate 31, completing the packaging process of the paper stack.

[0034] Obviously, when packaging the paper stack, the bottom surface of the push plate 31 needs to be located above the upper plastic film 51 and have an appropriate distance range with the upper plastic film 51. If the bottom surface of the push plate 31 is located below the upper plastic film 51, when the push plate 31 pushes the closing film 52 for sealing, the push plate 31 will push the closing film 52 to squeeze onto the side wall of the paper stack, causing the paper stack to deform and affecting the packaging quality of the paper stack. If the bottom surface of the push plate 31 is located above the upper plastic film 51, but the distance between the bottom surface of the push plate 31 and the upper plastic film 51 is large, after the push plate 31 pushes the closing film 52 for sealing, it is possible that the closing film 52 cannot be pressed onto the upper plastic film 51. At this time, the packaging bag 5 wraps the paper stack loosely. In the subsequent transportation process, the loose packaging is likely to cause relative movement between the paper stacks, which is likely to cause the packaging bag 5 to spread out.

[0035] In order 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. A guide unit 4 is provided on the conveying unit 1. In the horizontal extension stroke of the telescopic rod 32, under the guidance of the guide unit 4, the push plate 31 moves horizontally and simultaneously slides vertically on the adjustment seat 34 so that the bottom of the push plate 31 fits the closing film 52 of the outer packaging bag 5 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 inclined toward the surface of the plastic film 51 (in this embodiment, the inclined section 422 is inclined downward), the guide plate 41 is horizontally arranged, and the guide plate 41 extends toward the direction of the conveying table surface, a vertical first slide groove 341 is provided on the adjustment seat 34, the push plate 31 is slidably installed in the first slide groove 341 through a first slider 343, the first slider 343 and the top wall of the first slide groove 341 are connected by a traction spring 342, a vertical second slide groove 311 is further provided on the side wall of the push plate 31 close to the guide plate 41, a 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 a connecting spring 312, and 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 push plate 31 pushes the closing film 52 to bend in the direction of the plastic film 51. As the telescopic rod 32 extends, the push plate 31 slides along the guide groove 42 on the guide plate 41 through the second slider 313. When the second slider 313 slides along the horizontal section 421, the push plate 31 pushes the closing film 52 to approach the upper plastic film 51. When the second slider 313 leaves the horizontal section 421 and enters the inclined section 422 and slides, the push plate 31 pushes the closing film 52 to gradually press on the surface of the upper plastic film 51. When the push plate 31 pushes the closing film 52 to press on the upper plastic film 51, the bottom of the push plate 31 is blocked by the packaging bag 5 with the paper stack and cannot continue to descend. The second slider 313 must continue to move downwardly along the inclined section 422. At this time, as the telescopic rod 32 continues to extend, the push plate 31 slides on the first slide groove 341 of the adjustment seat 34 to ensure that the push plate 31 does not drop vertically. At the same time, the second slider 313 also slides downwardly along the groove of the second slide groove 311 to ensure that the second slider 313 can continue to move downwardly along the inclined section 422. At this time, the push plate 31 pushes the closing film 52 to move horizontally along the surface of the upper plastic film 51. When the push plate 31 passes through the adhesive layer 53 on the closing film 52, the adhesive layer 53 and the upper plastic film 51 can be more tightly bonded under the extrusion of the push plate 31, thereby improving the sealing effect of the packaging bag 5.

[0038] Obviously, with the different thicknesses of the paper stack to be packaged, when the second slider 313 slides along the inclined section 422 of the guide groove 42, the timing at which the push plate 31 abuts against the upper plastic film 51 is also different. The thicker the paper stack to be packaged, the earlier the push plate 31 will abut against the surface of the upper plastic film 51. Thus, the timing at which the push plate 31 translates 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 push plate 31 may squeeze the closing film 52 and abut against the upper plastic film 51, resulting in the adhesive layer 53 being located behind the movement path of the push plate 31. That is, with the movement of the push plate 31, the push plate 31 cannot pass through the adhesive layer 53. Thus, the push plate 31 cannot squeeze the adhesive layer 53, which may easily cause the packaging bag 5 to be not tightly closed, affecting the packaging quality of the packaging bag 5.

[0039] In order to solve the above problems, preferably, a reset groove 43 is further provided on the guide plate 41, 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 section 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, wherein the reset groove 43 is divided into a first reset section 431 and a second reset section 432, wherein the first reset section 431 is horizontally arranged, and the second reset section 432 is inclined upwardly arranged, and may also be an arc-shaped groove, when projected from top to bottom in the vertical direction, the projection length of the inclined section 422 on the horizontal plane is consistent with the length of the first reset section 431, and the projection length of the second reset section 432 on the horizontal plane is also consistent with the length of the horizontal section 421, wherein the connection between the reset groove 43 and the guide groove 42 is provided with a unidirectional deflection mechanism 44, 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 limit the second slider 313 entering the first reset section 431 to re-enter the inclined section 422, and the second slider 313 returning to the horizontal section 421 to re-enter the second reset section 432. The one-way deflection mechanism 44 can select a common baffle, a rotating shaft and a torsion spring combination to limit the rotation range of the baffle within a limited range of 90 degrees. When the torsion spring is in a 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, and the other side is limited. The one-way deflection mechanism 44 is a prior art, and its principle is not repeated.

[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 enter the guide groove 42 again and can only move along the reset groove 43. At this time, the second slider 313 moves along the first movement of the reset groove 43. The reset section 431 slides. Since the first reset section 431 is horizontally arranged, 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 consistent with the projection 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 then contacts the upper plastic film 51. Therefore, when the second slider 313 moves to the position where the first reset section 431 is away from the inclined section 422, the bottom of the push plate 31 gradually approaches and then contacts the upper plastic film 51. When the second slider 313 is at the end of the segment 422, the moving distance of the push plate 31 on the plastic film 51 when the second slider 313 is reset is greater than the distance of the push plate 31 on the plastic film 51 when sealing. Even if, when the packaging bag 5 is sealed, the adhesive layer 53 is located behind the moving path of the push plate 31, it is possible to ensure that the push plate 31 passes through the adhesive layer 53 on the sealing film 52 and squeezes the adhesive layer 53, thereby ensuring the tightness of the packaging bag 5 when it is closed and improving 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 its initial state, waiting for the next packaging bag 5 to be sealed.

[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 closing film 52 and the upper plastic film 51 are not yet adhered 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 closing film 52, when the push plate 31 moves, under the action of friction, the push plate 31 is easy to move synchronously with the closing film 52, causing the closing film 52 to move on the upper plastic film 51, affecting the sealing quality of the packaging bag 5.

[0042] In order to solve the above problem, a soft pressing plate 35 is further provided on the plate surface of the push plate 31 close to the closing membrane 52. The top of the soft pressing plate 35 is fixedly connected to the plate surface of the push plate 31, the bottom surface of the soft pressing plate 35 is lower than the bottom surface of the push plate 31, and the bottom end of the soft pressing plate 35 is arc-shaped and tilted away from 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 through the second slider 313. When the second slider 313 slides along the inclined section 422, the push plate 31 brings the material pressing soft plate 35 to push the closing film 52 to gradually press on the surface of the upper plastic film 51. The bottom of the material pressing soft plate 35 on the push plate 31 first pushes the closing film 52 to contact with the upper plastic film 51. As the telescopic rod 32 continues to extend, the material pressing soft plate 35 pulls the closing film 52 on the upper plastic film 51 toward away from the package The packing bag 5 moves in the opening direction until the sealing film 52 is in a taut state, so that the sealing film 52 can tightly wrap the side wall of the paper stack at the opening of the packaging bag 5. At this time, the bottom surface of the push plate 31 is also pressed on 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 reset groove 43 on the guide plate 41 through the second slider 313. 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, due to the pressure The material pressing soft plate 35 is pressed on the surface of the sealing film 52. Under the action of friction, the material pressing soft plate 35 does not move at first. After the push plate 31 moves a certain distance, it pulls the material pressing soft plate 35 to move. When the push plate 31 moves relative to the material pressing soft plate 35, the bottom surface of the push plate 31 translates on the surface of the sealing film 52. During the translation process, the sealing film 52 is bonded to the upper plastic film 51 through the adhesive layer 53 on the sealing film 52. At this time, under the action of the material pressing soft plate 35, the sealing film 52 will not be pushed by the push plate 31. The plate 31 moves with the movement of the pressing plate 31, so that the sealing film 52 can tightly wrap the paper stack, thereby improving the packaging effect of the paper stack; and, the bottom end of the pressing soft plate 35 is arc-shaped and tilted away from the push plate 31. When the pressing soft plate 35 pushes the sealing film 52 to press onto the surface of the plastic film 51, the pressing soft plate 35 is squeezed by the upper plastic film 51, and the bottom of the pressing soft plate 35 will be deformed in the direction away from the push plate 31 and the telescopic rod 32, preventing the pressing soft plate 35 from being squeezed between the push plate 31 and the telescopic rod 32, thereby affecting the sealing quality of the subsequent packaging bag 5.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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 above 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.
