Technical Field

[0001] The utility model relates to the technical field of packaging paper products, in particular to a turnover device for thin packaging paper products. Background Art

[0002] The most common packaging paper products are soft tissue paper or printing packaging paper. Among them, soft tissue paper is a very common product in daily life. Hereinafter, soft tissue paper will be taken as an example for illustration. The principle of printing packaging paper or other paper products is similar. Generally, soft tissue paper has a large number of sheets and a relatively thick thickness, so the center of gravity of the whole soft tissue paper is relatively low. With the development of society, there is also a need for soft tissue paper with a smaller number of sheets, which has a thinner thickness and a relatively high center of gravity for the whole soft tissue paper. If the traditional method of feeding material in cooperation with an inclined slope is used for turnover, due to the relatively high center of gravity of the thin soft tissue paper, it cannot be quickly turned over during the turnover process, and the placement is also unstable, resulting in a low turnover success rate, and it cannot be arranged and stacked according to a certain continuous packaging specification and pushed into the packaging bag together to complete the continuous packaging and sealing.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. First, the present utility model uses the first feeding conveyor belt and the second feeding conveyor belt to horizontally convey the packaging paper products. Among them, the conveying speed of the second feeding conveyor belt is greater than that of the first feeding conveyor belt, so as to separate the packaging paper products at intervals, leaving enough distance between them, so that the subsequent packaging paper products have enough stopping time and stopping distance; it is convenient to wait for the inclined receiving plate to move vertically downward, so as to facilitate subsequent stacking; secondly, the inclined receiving plate supports the packaging paper products; by the cooperation of the inclined receiving plate and the curved support plate, the packaging paper products are placed on the inclined receiving plate and lean on the curved support plate to achieve stable support and inclined stacking; thirdly, the inclined receiving plate can also move vertically downward, so that the packaging paper products continuously entering the inclined receiving plate can be neatly stacked, preparing for subsequent flipping; finally, a lever is installed under the inclined receiving plate, and the lever rotates to flip the inclined stacked packaging paper products along the curved support plate onto the longitudinal conveying plate; through the above combined movements, the present utility model separates and places the packaging paper products neatly and obliquely, so as to stack them neatly and flip smoothly, improving the product qualification rate.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only one embodiment of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 to 8 , the present invention provides a thin wrapping paper product flipping device.

[0030] As Figure 1As shown, the flipping device includes a frame 1, on which a first feeding conveyor belt 31 is horizontally installed. The first feeding conveyor belt 31 is used to horizontally convey the packaging paper products 2. A first synchronous driving assembly 41 is installed on the first feeding conveyor belt 31. The first feeding conveyor belt 31 is in contact with the lower surface of the packaging paper products 2, and the first synchronous driving assembly 41 is in contact with the upper surface of the packaging paper products 2. The first feeding conveyor belt 31 and the first synchronous driving assembly 41 together horizontally convey the packaging paper products 2, and the speeds of the upper and lower surfaces are the same for synchronous horizontal conveyance. Among them, the limiting plates on both sides of the first feeding conveyor belt 31 can also limit the left and right sides of the packaging paper products 2 to guide the horizontal conveyance of the packaging paper products 2. Further, the limiting plates can be longitudinally adjusted to adapt to different specifications of the packaging paper products 2.

[0031] A second feeding conveyor belt 32 is installed on one side of the first feeding conveyor belt 31 for continuous horizontal conveyance. Among them, the conveying speed of the second feeding conveyor belt 32 is greater than that of the first feeding conveyor belt 31, so as to separate the packaging paper products 2 at intervals, leaving enough distance between them, so that the subsequent packaging paper products 2 have enough stopping time and stopping distance; it is convenient to wait for the operation of the subsequent workstations so as not to cause movement interference.

[0032] Similarly, a second synchronous driving assembly 42 is installed on the second feeding conveyor belt 32. Among them, the second feeding conveyor belt 32 is in contact with the lower surface of the packaging paper products 2, and the second synchronous driving assembly 42 is in contact with the upper surface of the packaging paper products 2. The second feeding conveyor belt 32 and the second synchronous driving assembly 42 together horizontally convey the packaging paper products 2, and the speeds of the upper and lower surfaces are the same for synchronous horizontal conveyance.

[0033] As Figure 1 shown, an inclined receiving plate 51 is installed at the end of the second feeding conveyor belt 32. The inclined receiving plate 51 is used to receive the packaging paper products 2 conveyed by the second feeding conveyor belt 32 and stably place the packaging paper products 2; the packaging paper products 2 are also inclined on the inclined receiving plate 51. In order to support the packaging paper products 2, a curved support plate 52 is installed on one side of the inclined receiving plate 51. The packaging paper products 2 lean on the curved support plate 52, and the stable support and inclined placement of the packaging paper products 2 are realized by the cooperation of the inclined receiving plate 51 and the curved support plate 52.

[0034] Since the packaging paper products 2 are separated at intervals on the second feeding conveyor belt 32 and there is enough distance, while the second feeding conveyor belt 32 continuously horizontally inputs the packaging paper products 2, the inclined receiving plate 51 has enough time to move vertically downward, so that the packaging paper products 2 are inclined and stacked on the inclined receiving plate 51 and the curved support plate 52.

[0035] Further, a lever 6 is installed at the lower part of the inclined material receiving plate 51. The lever 6 rotates to turn the inclined stacked packaging paper products 2 over along the curved support plate 52 onto the longitudinal conveying plate 7.

[0036] Furthermore, as Figure 3 shown, the inclined material receiving plate 51 inclines towards the curved support plate 52. The right side of the inclined material receiving plate 51 is higher and the left side is lower. The inclined material receiving plate 51 supports the bottom surface of the packaging paper products 2, and the packaging paper products 2 lean against the curved support plate 52 obliquely. The curved support plate 52 supports the side surface of the packaging paper products 2. The lever 6 is placed below the inclined material receiving plate 51 and is horizontally placed longitudinally, so that an included angle is formed between the inclined material receiving plate 51 and the lever 6, which greatly reduces the contact area between the lever 6 and the inclined material receiving plate 51.

[0037] Each part and component will be introduced in detail below.

[0038] As Figure 7 shown, first rotating shafts 311 and second rotating shafts 312 are respectively installed at two ends of the first feeding conveyor belt 31. Among them, the first rotating shaft 311 is a driving shaft that drives the first feeding conveyor belt 31 to move horizontally, and the second rotating shaft 312 is a driven shaft that assists the first feeding conveyor belt 31; further, a first driving motor 313 is installed below the first feeding conveyor belt 31. The first driving motor 313 is fixed on the frame 1. The first driving motor 313 drives the first rotating shaft 311 to rotate through a first synchronous belt 314, thereby driving the first feeding conveyor belt 31 to move horizontally.

[0039] As Figure 7 shown, third rotating shafts 321 and fourth rotating shafts 322 are respectively installed at two ends of the second feeding conveyor belt 32. Among them, the third rotating shaft 321 is a driving shaft that drives the second feeding conveyor belt 32 to move horizontally, and the fourth rotating shaft 322 is a driven shaft that assists the second feeding conveyor belt 32; further, as Figure 5 shown, the first rotating shaft 311 drives the third rotating shaft 321 to rotate through a second synchronous belt 323, thereby driving the second feeding conveyor belt 32 to move horizontally.

[0040] As Figure 5As shown, the diameter of the first rotating shaft 311 is greater than that of the third rotating shaft 321, so that the conveying speed of the second feeding conveyor belt 32 is greater than that of the first feeding conveyor belt 31; the speed of the previous wrapping paper product 2 is greater than that of the subsequent wrapping paper product 2, so that the wrapping paper products 2 on the second feeding conveyor belt 32 are spaced apart, leaving enough distance between them, so that the subsequent wrapping paper product 2 has enough stopping time and stopping distance; it is convenient to wait for the operation of the subsequent workstations, so as to avoid movement interference.

[0041] As Figures 5 to 7 shown, the first synchronous drive assembly 41 includes a plurality of first support rods 411 installed on the frame 1. There are four first support rods 411, which are arranged around respectively; a first frame body 412 is slidably installed inside the first support rod 411, and the first frame body 412 can slide vertically along the first support rod 411, so as to adjust the overall vertical height of the first frame body 412.

[0042] As Figure 7 shown, a first drive belt 413 is installed inside the first frame body 412. Three fifth rotating shafts 414 are installed inside the first drive belt 413. The fifth rotating shafts 414 are arranged in a triangle. The bottom of the first drive belt 413 contacts the upper surface of the wrapping paper product 2 and is synchronized with the first feeding conveyor belt 31 in speed, and the wrapping paper product 2 is horizontally conveyed.

[0043] When the wrapping paper product 2 needs to stop moving, the first drive belt 413 and the first feeding conveyor belt 31 stop moving at the same time, and the wrapping paper product 2 is stopped from the upper and lower surfaces, and it can stop in time or stop synchronously. When the wrapping paper product 2 needs to restart, the first drive belt 413 and the first feeding conveyor belt 31 are driven at the same time, and the wrapping paper product 2 is driven from the upper and lower surfaces, and it can start quickly and be horizontally conveyed.

[0044] Specifically, as Figure 6 shown, the first drive motor 313 drives the fifth rotating shaft 414 to rotate through the third synchronous belt 415, so as to drive the first drive belt 413 to move horizontally; as Figure 6 shown, the third synchronous belt 415 is installed inside the first synchronous belt 314, and the first drive motor 313 outputs power to the third synchronous belt 415 and the first synchronous belt 314; it can be seen that the power source for driving the wrapping paper product 2 comes from the first drive motor 313.

[0045] In order to adjust the vertical height of the first frame body 412, the first frame body 412 and the first support rod 411 are slidably connected through a first linear bearing 416 to achieve the vertical sliding of the first frame body 412; a first support plate 417 is installed at the end of the first support rod 411, and a first rotating screw 418 is installed on the upper part of the first frame body 412. By driving the rotation of the first rotating screw 418, the vertical height of the first frame body 412 is adjusted, and then the vertical height of the first driving belt 413 is adjusted, so as to ensure contact with the upper surface of the packaging paper product 2 and drive the packaging paper product 2 to move horizontally; thus, it can adapt to packaging paper products 2 with different thicknesses.

[0046] Similarly, the structure of the second synchronous drive assembly 42 is similar to that of the first synchronous drive assembly 41. Specifically, the second synchronous drive assembly 42 includes a plurality of second support rods 421 installed on the frame 1. There are four second support rods 421, which are arranged around respectively; a second frame body 422 is slidably installed inside the second support rod 421, and the second frame body 422 can slide vertically along the second support rod 421, so as to adjust the overall vertical height of the second frame body 422.

[0047] As Figure 7 shown, a second driving belt 423 is installed inside the second frame body 422, and a number of sixth rotating shafts 424 are installed inside the second driving belt 423. The sixth rotating shafts 424 can be arranged in a triangular shape or in other shapes. It is necessary to ensure that the bottom is horizontally horizontal, so that the bottom of the second driving belt 423 contacts the upper surface of the packaging paper product 2 and is synchronized with the second feeding conveyor belt 32 in speed to horizontally convey the packaging paper product 2; the third rotating shaft 321 drives the sixth rotating shaft 424 to rotate through a fourth synchronous belt 425, so as to drive the second driving belt 423 to move horizontally.

[0048] Similarly, the second driving belt 423 and the second feeding conveyor belt 32 move simultaneously and stop simultaneously; the packaging paper product 2 can be quickly stopped and quickly started; when the packaging paper product 2 needs to stop moving, the second driving belt 423 and the second feeding conveyor belt 32 stop moving simultaneously and stop the packaging paper product 2 from the upper and lower surfaces, which can be stopped in time or synchronously. When the packaging paper product 2 needs to be restarted, the second driving belt 423 and the second feeding conveyor belt 32 are driven simultaneously and drive the packaging paper product 2 from the upper and lower surfaces, which can be quickly started for horizontal transportation.

[0049] Furthermore, the power sources of the second drive belt 423, the second feed conveyor belt 32, the first drive belt 413 and the first feed conveyor belt 31 all come from the first drive motor 313, and the start and stop of the first drive motor 313 are controlled, so as to control the conveying process of the packaging paper product 2; when it is necessary to wait for the movement of the subsequent process, the start and stop of the first drive motor 313 can be controlled by the controller.

[0050] In order to adjust the vertical height of the second frame 422, the second frame 422 is slidably connected to the second support rod 421 via a second linear bearing 426 to achieve vertical sliding of the second frame 422; a second support plate 427 is installed at the end of the second support rod 421, and a second rotating screw 428 is installed on the upper part of the second frame 422 to drive the second rotating screw 428 to rotate, thereby adjusting the vertical height of the second frame 422, and then adjusting the vertical height of the second driving belt 423, thereby ensuring contact with the upper surface of the packaging paper product 2, driving the packaging paper product 2 to move horizontally; thereby, it can adapt to packaging paper products 2 of different thicknesses.

[0051] like Figure 2 As shown, the inclined material receiving plate 51 is transmission-connected with the vertical driving assembly 53, and the vertical driving assembly 53 drives the inclined material receiving plate 51 to vertically reciprocate. The vertical driving assembly 53 can be a vertical module or a multi-stage output cylinder.

[0052] However, in this embodiment, the vertical drive assembly 53 includes a second drive motor 531 mounted on the frame 1, a fifth synchronous belt 532 mounted at one end of the second drive motor 531 and driven by the second drive motor 531, and a vertical slider 533 mounted on the fifth synchronous belt 532; Figure 2 In the embodiment, the vertical slider 533 is fixedly mounted on the fifth synchronous belt 532 and vertically reciprocates together with the fifth synchronous belt 532; the vertical slider 533 is mounted on one end of the inclined receiving plate 51. Figure 2 In the figure, the vertical slider 533 is L-shaped and is installed at the upper end of the inclined material receiving plate 51; the second driving motor 531 drives the inclined material receiving plate 51 to move vertically downward through the fifth synchronous belt 532 and the vertical slider 533, so that the packaging paper products 2 are stacked at an angle; the inclined stacked packaging paper products 2 can also be driven vertically upward to increase the vertical height of the packaging paper products 2, so as to better cooperate with the lever 6, and flip the packaging paper products 2 along the curved support plate 52 to the longitudinal conveying plate 7.

[0053] like Figure 3As shown, the lever 6 is drivingly connected to the third driving motor 61; the lever 6 is installed at the end of the third driving motor 61. The inclined material receiving plate 51, the bent support plate 52, and the longitudinal conveying plate 7 are all provided with receiving grooves 521 for accommodating the lever 6. The lever 6 is inserted into the inside of the receiving groove 521 and is located below the inclined material receiving plate 51. It is driven by the third driving motor 61 to rotate. In this way, the lever 6 can successively pass through the inclined material receiving plate 51, the bent support plate 52, and the longitudinal conveying plate 7, and flip the inclined stacked packaging paper products 2 onto the longitudinal conveying plate 7 along the bent support plate 52.

[0054] The lever 6 is located below the inclined material receiving plate 51. When a plurality of packaging paper products 2 are inclinedly stacked on the inclined material receiving plate 51, the lever 6 rotates under the drive of the third driving motor 61, and flips the inclined stacked packaging paper products 2 onto the longitudinal conveying plate 7 along the bent support plate 52. When the inclined material receiving plate 51 stacks the packaging paper products 2 again, the lever 6 needs to return below the inclined material receiving plate 51 first before the packaging paper products 2 can be stacked continuously. In this way, the stacking and conveying efficiency is relatively low.

[0055] In order to improve the stacking and conveying efficiency, in this embodiment, a longitudinal driving assembly 62 is added. The longitudinal driving assembly 62 is drivingly connected to the lever 6. The longitudinal driving assembly 62 drives the lever 6 to move longitudinally, so that the packaging paper products 2 move longitudinally along the longitudinal conveying plate 7. The longitudinal driving assembly 62 also drives the lever 6 to longitudinally insert below the inclined material receiving plate 51, so that the stacking of the subsequent packaging paper products 2 and the flipping and longitudinal transfer of the previous packaging paper products 2 can be carried out synchronously. Specifically, while stacking the subsequent packaging paper products 2, the previous packaging paper products 2 can be flipped and longitudinally transferred at the same time. After the longitudinal transfer is completed, the longitudinal driving assembly 62 drives the lever 6 to move longitudinally, and longitudinally inserts the lever 6 below the inclined material receiving plate 51 to achieve another flipping and longitudinal transfer, thereby improving the stacking and conveying efficiency.

[0056] Further, as Figure 3 and Figure 4 shown, the longitudinal driving assembly 62 includes a fourth driving motor 621 installed on the frame 1, a sixth synchronous belt 622 installed at one end of the fourth driving motor 621 and driven by the fourth driving motor 621, and a longitudinal slider 623 installed on the sixth synchronous belt 622. The upper part of the longitudinal slider 623 is provided with the third driving motor 61, and the lower part is sleeved with a longitudinal slide rail 624. The third driving motor 61 and the lever 6 longitudinally slide along the longitudinal slide rail 624 through the longitudinal slider 623, thereby longitudinally conveying the packaging paper products 2.

[0057] Even further, as Figure 3As shown, the inclined material receiving plate 51 is arranged to be inclined, and the lever 6 is also arranged at the lower part of the inclined material receiving plate 51, so that when the lever 6 is longitudinally inserted into the bottom of the packaging paper product 2, it will not contact the packaging paper product 2, or only contact the side of the packaging paper product 2, which greatly reduces the contact area, allows the lever 6 to be smoothly inserted, and the packaging paper product 2 can be smoothly turned over, reduces the breakage rate of the packaging paper product 2 when inserted, and improves the product qualification rate.

[0058] like Figure 4 As shown, the end of the lever 6 is provided with an inclined chamfer, so that the lever 6 is more convenient to insert longitudinally and is not easy to damage the bottom of the packaging paper product 2.

[0059] like Figure 2 As shown, the side of the inclined material receiving plate 51 that contacts the second feeding conveyor belt 32 is provided with an inclined chamfer, so that the packaging paper product 2 can enter the inclined material receiving plate 51 more easily.

[0060] like Figure 8 As shown, the longitudinal conveying plate 7 is provided with a first limiting plate 71 on one side and a second limiting plate 72 on the other side. A width position adjusting assembly 73 for adjusting the width distance between the first limiting plate 71 and the second limiting plate 72 is provided on the upper portion of the longitudinal conveying plate 7, so that it can adapt to packaging paper products 2 of various specifications. At the same time, the first limiting plate 71 and the second limiting plate 72 also limit the packaging paper products 2 on the longitudinal conveying plate 7 to prepare for subsequent packaging.

[0061] Further, such as Figure 8 As shown, the width position adjustment assembly 73 includes a forward screw rod 731 that is transmission-connected to one end of the first limiting plate 71, a reverse screw rod 732 that is transmission-connected to one end of the second limiting plate 72, a forward and reverse screw rod 733 that is transmission-connected to the other end of the first limiting plate 71 and the other end of the second limiting plate 72, a first chain 734 installed between the forward and reverse screw rods 733 and the forward screw rod 731, a second chain 735 installed between the forward and reverse screw rods 733 and the reverse screw rod 732, and a rotating handle 736 installed at one end of the forward screw rod 731, wherein the forward screw rod 731 is provided with a forward thread that is threadedly connected to one end of the first limiting plate 71, the reverse screw rod 732 is provided with a reverse thread that is threadedly connected to one end of the second limiting plate 72, the forward thread of the forward and reverse screw rod 733 is transmission-connected to the other end of the first limiting plate 71, and the reverse thread of the forward and reverse screw rod 733 is transmission-connected to the other end of the second limiting plate 72.

[0062] The movement principle of the width position adjustment assembly 73 mainly utilizes the different rotation directions of the forward screw 731 and the reverse screw 732, as follows:

[0063] Step S1: Manually drive the rotating handle 736 to rotate, driving the forward rotating lead screw 731;

[0064] Step S2: Through the first chain 734, the forward rotating lead screw 731 rotates synchronously with the forward and reverse lead screw 733. The forward threads of the forward rotating lead screw 731 and the forward and reverse lead screw 733 act together to drive the first limit plate 71 to move horizontally;

[0065] Step S3: Through the second chain 735, the forward and reverse lead screw 733 rotates synchronously with the reverse rotating lead screw 732. The reverse threads of the reverse rotating lead screw 732 and the forward and reverse lead screw 733 act together to drive the second limit plate 72 to move horizontally;

[0066] Step S4: Since the forward rotating lead screw 731 and the reverse rotating lead screw 732 have opposite helix directions, the first limit plate 71 and the second limit plate 72 are driven to approach or move away from each other simultaneously, thereby adjusting the width distance between the first limit plate 71 and the second limit plate 72.

[0067] The operating steps of the flipping device:

[0068] Step S1: Manually or automatically place the packaging paper product 2 on the first feeding conveyor belt 31. The first feeding conveyor belt 31 and the first synchronous driving assembly 41 together perform horizontal conveyance on the packaging paper product 2, and the speeds of the upper and lower surfaces are the same for synchronous horizontal conveyance;

[0069] Step S2: The packaging paper product 2 enters between the second feeding conveyor belt 32 and the second synchronous driving assembly 42 and continues to be horizontally conveyed. The second feeding conveyor belt 32 and the second driving belt 423 have synchronous speeds; among them, the conveying speed of the second feeding conveyor belt 32 is greater than the conveying speed of the first feeding conveyor belt 31, so as to separate the packaging paper products 2 at intervals, leaving enough distance between them to facilitate the operation of the subsequent workstations and prevent movement interference;

[0070] Step S3: The packaging paper product 2 enters onto the inclined receiving plate 51 and leans against the curved supporting plate 52;

[0071] Step S4: The second driving motor 531 drives the inclined receiving plate 51 to move vertically downward through the fifth synchronous belt 532 and the vertical slider 533, thereby stacking the packaging paper products 2 in an inclined manner;

[0072] Step S5: After stacking to the predetermined quantity, the second driving motor 531 drives the inclined stacked packaging paper products 2 to move vertically upward;

[0073] Step S6: The fourth driving motor 621 drives the lever 6 to longitudinally insert into the bottom of the inclined receiving plate 51;

[0074] Step S7: The lever 6 rotates driven by the third driving motor 61, and flips the obliquely stacked paper packaging products 2 onto the longitudinal conveying plate 7 along the curved support plate 52;

[0075] Step S8: The fourth driving motor 621 drives the lever 6 to move longitudinally, so as to longitudinally convey the paper packaging products 2 on the longitudinal conveying plate 7.

Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
