Description

Technical Field

[0001] This application relates to the field of paper box adjustment technology, and in particular to a paper box flipping device. Background Technology

[0002] During the decoration process of packaging paper box products, the production date needs to be printed on the back of the paper box product. Next, it needs to enter the packaging channel of the laminating machine so that the front of the paper box product can be sealed. Then, the back of the paper box product needs to be turned over so that the front of the paper box product is facing up. The direction of the sealing is different from the direction of the printed production date, so it needs to be reversed before sealing.

[0003] In existing technologies, paper box products are often manually flipped and rotated. However, due to fatigue caused by prolonged operation, the paper box products are easily forgotten to be flipped after being flipped and rotated. As a result, when the laminating machine is used for lamination and packaging, the front of the paper box product is sealed and ironed on the back instead, which increases the defect rate. In addition, when manually flipping and rotating paper box products, the stable operating time cannot be guaranteed, which reduces production efficiency. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] Hereinafter, embodiments will be described with reference to the accompanying drawings, which are not intended to limit the disclosure described in the claims.

[0021] Please see Figures 1-4 The following is combined with Figures 1-4 A detailed description of a paper box flipping device provided in the embodiments of this application will be given.

[0022] This application provides a paper box flipping device, such as... Figures 1-4 As shown, specifically, the paper box flipping device includes a reversing conveyor mechanism 1, a flipping mechanism 2, and a paper box conveying mechanism 3; wherein, the flipping mechanism 2 is inclinedly disposed between the reversing conveyor mechanism 1 and the paper box conveying mechanism 3, and the connection between the flipping mechanism 2 and the reversing conveyor mechanism 1 is higher than the connection between the flipping mechanism 2 and the paper box conveying mechanism 3; the flipping mechanism 2 includes an inclined surface 21 and a flipping blocking shaft 22, one end of the inclined surface 21 is connected to the reversing conveyor mechanism 1, and the other end of the inclined surface 21 is connected to the paper box conveying mechanism 3, and the flipping blocking shaft 22 is disposed at the connection between the inclined surface 21 and the paper box conveying mechanism 3, and the end of the inclined surface 21 connected to the reversing conveyor mechanism 1 is lower than the conveying surface in the reversing conveyor mechanism 1.

[0023] In this embodiment, the cardboard box 5 is a rigid cardboard box with a certain weight. For example, the cardboard box 5 can be a rigid gift box or a rigid packaging box, etc. The cardboard box flipping device is used to change the direction and flip the cardboard box 5 with the back side facing up. In a specific embodiment, the cardboard box flipping device includes a reversing conveying mechanism 1, a flipping mechanism 2, and a cardboard box conveying mechanism 3. The reversing conveying mechanism 1 is used to rotate the cardboard box 5 90 degrees clockwise to change the direction of the cardboard box 5. The flipping mechanism 2 is used to flip the cardboard box 5 180 degrees to flip the cardboard box 5 with the back side facing up to the front side facing up. The cardboard box conveying mechanism 3 is used to carry the flipped cardboard box 5 and convey the cardboard box 5 with the front side facing up so as to carry out the next operation on the cardboard box 5. In this way, the reversing and flipping operation of the cardboard box 5 can be automated, reducing the human error rate and improving the operating efficiency of reversing and flipping.

[0024] In one specific embodiment, the flipping mechanism 2 is inclined, and the connection between the flipping mechanism 2 and the reversing conveying mechanism 1 is higher than the connection between the flipping mechanism 2 and the paper box conveying mechanism 3, so as to form a height difference. Thus, the flipping process of the paper box 5 can be realized by using the inclined flipping mechanism 2. Specifically, when the paper box 5 is transported to the inclined surface 21, since the end of the inclined surface 21 connected to the reversing conveying mechanism 1 is lower than the conveying surface in the reversing conveying mechanism 1, and the inclined surface 21 is in an inclined state, the paper box 5 tends to tilt forward during the falling process. At the same time, the paper box 5 slides down, and the long side of the paper box 5 abuts against the flipping blocking shaft 22, so that the side of the paper box 5 in contact with the flipping blocking shaft 22 is resisted, but the other side of the paper box 5 continues to move forward due to inertia, thereby realizing the flipping process of the paper box 5.

[0025] In practical applications, both the inclined surface 21 and the flipping blocking shaft 22 are made of stainless steel. In one alternative implementation, such as Figure 2 and Figure 3As shown, a flipping assist spring 23 is provided on the inclined surface 21. The flipping assist spring 23 is located at one end near the connection between the flipping mechanism 2 and the reversing transmission mechanism 1.

[0026] Specifically, during the descent of the cardboard box 5, the flip-assist spring 23 is compressed by the cardboard box 5. At this time, the flip-assist spring 23 has a certain elasticity, which provides a certain lifting force to the cardboard box 5, thereby providing a flipping force. At the same time, with the resistance of the side of the cardboard box 5 in contact with the flip-stop shaft 22, the cardboard box 5 can be ensured to complete a 180-degree flipping process. Furthermore, due to the lifting effect of the flip-assist spring 23, the stability of the cardboard box 5 can be increased. For example, see [link to relevant documentation]. Figure 3 It presents a schematic diagram of the flipping of cardboard box 5.

[0027] In practical applications, the flip-assist spring 23 has a certain range of width along the transverse direction of the inclined surface 21. For example, the width of the flip-assist spring 23 is equal to half the width of the inclined surface 21, or the width of the flip-assist spring 23 is equal to one-third the width of the inclined surface 21.

[0028] In one specific embodiment, the flipping mechanism 2 further includes a connecting baffle 24, wherein one end of the connecting baffle 24 is connected to the reversing conveying mechanism 1, the other end of the connecting baffle 24 is connected to the paper box conveying mechanism 3, and the connecting baffle 24 is disposed on the lower side of the inclined surface 21, and the connecting baffle 24 is used to support the inclined surface 21.

[0029] In an optional embodiment, the reversing conveying mechanism 1 includes a reversing component and a reversing conveying frame; wherein the reversing component is disposed on the reversing conveying frame, one end of the reversing conveying frame is connected to one end of the inclined surface 21, and the end of the reversing conveying frame connected to the inclined surface 21 is lower than the conveying surface in the reversing conveying frame.

[0030] In this embodiment, the reversing component is used to perform a reversing operation on the paper box 5, and the reversing conveying frame is used to convey and adjust the height of the paper box 5. Thus, by combining the reversing component and the reversing conveying frame, an automated reversing operation of the paper box 5 can be achieved.

[0031] In one specific implementation, such as Figure 1As shown, the reversing conveyor frame includes a first conveyor belt support 11, a first conveyor belt drive 12, and a first conveyor belt 13; wherein, the first conveyor belt drive 12 and the first conveyor belt 13 are both disposed on the first conveyor belt support 11, and the first conveyor belt drive 12 is disposed on one side of the first conveyor belt 13; the first conveyor belt support 11 includes a first conveyor belt support structure 111 and a plurality of first height adjustment members 112, the first conveyor belt support structure 111 is disposed on the plurality of first height adjustment members 112, and the plurality of first height adjustment members 112 are respectively disposed around the first conveyor belt support structure 111, and the plurality of first height adjustment members 112 can adjust the height of the first conveyor belt 13.

[0032] Specifically, the first conveyor belt support 11 is used to support the first conveyor belt 13 and adjust the height of the first conveyor belt 13. In one embodiment, the first conveyor belt support 11 includes a first conveyor belt support structure 111 and a plurality of first height adjustment members 112. The first conveyor belt support structure 111 is used to support the first conveyor belt 13, and the first height adjustment members 112 are used to adjust the height of the first conveyor belt 13. This allows a height difference to be formed between the first conveyor belt 13 in the reversing conveyor mechanism 1 and the second conveyor belt 33 in the paper box conveying mechanism 3, so that the flipping mechanism 2 can be tilted between the reversing conveyor mechanism 1 and the paper box conveying mechanism 3.

[0033] In practical applications, the first conveyor belt support structure 111 is connected to the support ends of multiple first height adjustment components 112 respectively. The first conveyor belt drive component 12 and the first conveyor belt 13 are both mounted on the first conveyor belt support structure 111. The first conveyor belt drive component 12 is used to drive the first conveyor belt 13. Specifically, the first conveyor belt drive component 12 can adjust the running speed of the first conveyor belt 13 and adjust the tension of the first conveyor belt 13.

[0034] Specifically, the first conveyor belt 13 can be a PU polyurethane textured conveyor belt.

[0035] In one specific implementation, such as Figure 1 As shown, the first conveyor belt drive component 12 includes a first drive motor 121, a first transmission roller 122, a first return roller 123, and a first motor speed regulator 124; wherein, the first drive motor 121, the first transmission roller 122, the first return roller 123, and the first motor speed regulator 124 are all mounted on the first conveyor belt support structure 111, the first transmission roller 122 and the first return roller 123 are electrically connected to the drive end of the first drive motor 121, and the first motor speed regulator 124 can adjust the running speed of the first drive motor 121.

[0036] In practical applications, the first conveyor belt drive 12 also includes a first return roller tensioning mechanism 125, wherein the first return roller tensioning mechanism 125 is disposed on the first conveyor belt support structure 111, the first return roller tensioning mechanism 125 is electrically connected to the drive end of the first drive motor 121, and the first return roller tensioning mechanism 125 is used to adjust the tension of the first conveyor belt 13 by driving the first return roller 123.

[0037] Specifically, the first drive motor 121 provides power to the first transmission roller 122 and the first return roller 123. The first transmission roller 122 and the first return roller 123 drive the first conveyor belt 13 to run. The first motor speed regulator 124 can adjust the running speed of the first drive motor 121, thereby adjusting the speed of the first conveyor belt 13.

[0038] In one specific implementation, such as Figure 2 As shown, the reversing assembly includes a first adjusting rod 14, a second adjusting rod 15, a third adjusting rod 16, an offset correction track 17, a reversing track 18, and a transmission track 19. The connecting ends of the first adjusting rod 14 and the second adjusting rod 15 are both located on one side of the first conveyor belt support structure 111, and the connecting end of the third adjusting rod 16 is located on the other side of the first conveyor belt support structure 111. The adjusting end of the first adjusting rod 14 is connected to the transmission track 19, the adjusting end of the second adjusting rod 15 is connected to the reversing track 18, and the adjusting end of the third adjusting rod 16 is connected to the offset correction track 17. The offset correction track 17, the reversing track 18, and the transmission track 19 all extend axially along the first conveyor belt support structure 111. The reversing track 18 and the offset correction track 17 are arranged opposite each other, forming a first transmission channel. The transmission track 19 is located at the end of the reversing track 18 furthest from the flipping mechanism 2.

[0039] Specifically, the first adjusting rod 14 is used to adjust the position of the transmission track 19, the second adjusting rod 15 is used to adjust the position of the reversing track 18, and the third adjusting rod 16 is used to adjust the position of the offset correction track 17. Thus, by adjusting the transmission track 19 with the first adjusting rod 14, adjusting the reversing track 18 with the second adjusting rod 15, and adjusting the offset correction track 17 with the third adjusting rod 16, a first transmission channel can be formed between the reversing track 18 and the offset correction track 17. The width of the first transmission channel is slightly greater than the length of the cardboard box 5. Simultaneously, one end of the transmission track 19 can be aligned with the reversing track. One end of the reversing track 18 is offset, and the vertical distance between the reversing track 18 and the first correction track 171 in the offset correction track 17 is less than the vertical distance between the transmission track 19 and the first correction track 171 in the offset correction track 17. As a result, the paper box 5 is driven by the first conveyor belt 13 and is transmitted along the transmission track 19. When it comes into contact with one end of the reversing track 18, it generates a certain resistance on one side of the paper box 5. However, the adjacent angle of the contact angle between the paper box 5 and one end of the reversing track 18 still moves forward under the drive of the first conveyor belt 13, which allows the paper box 5 to complete a 90-degree reversal. After the reversal is completed, it moves toward the flipping mechanism 2 in the first transmission channel.

[0040] In practical applications, such as Figure 2 As shown, there are two of each of the first adjusting rod 14, the second adjusting rod 15, and the third adjusting rod 16, which can improve the stability of the offset correction track 17, the reversing track 18, and the transmission track 19.

[0041] It should be noted that the end of the cardboard box 5 that contacts the reversing track 18 has a side protrusion. The thickness of the side protrusion is less than the vertical distance between the reversing track 18 and the transmission track 19, which can improve the accuracy of reversal. The center point of the flipping assist spring 23 is located on the center line of the first transmission channel. That is to say, the flipping assist spring 23 is kept in the center position of the first transmission channel to improve the accuracy of the flipping mechanism 2 in flipping the cardboard box 5.

[0042] In one specific implementation, such as Figure 2 As shown, the offset correction track 17 includes a first correction track 171 and a second correction track 172; wherein, the first correction track 171 is arranged parallel to the reversing track 18, there is a bending angle between the first correction track 171 and the second correction track 172, and the second correction track 172 bends in a direction away from the first correction track 171.

[0043] Specifically, during the reversing process of the paper box 5, it is necessary to ensure that the diagonal of the paper box 5 completes the reversing operation before the inflection point between the first correction track 171 and the second correction track 172. Specifically, the conveying speed of the first conveyor belt 13 can be adjusted by the first motor speed controller 124, thereby ensuring that the diagonal of the paper box 5 completes the reversing operation before the inflection point between the first correction track 171 and the second correction track 172, thus avoiding the first transmission channel restricting the reversing operation of the paper box 5.

[0044] In practical applications, the angle between the first correction track 171 and the second correction track 172 is an obtuse angle.

[0045] In one specific embodiment, the first conveyor belt support structure 111 is further provided with a movable fixed bracket 4 and a track 41. The extension direction of the track 41 is consistent with the axial direction of the first conveyor belt support structure 111, that is, the extension direction of the track 41 is consistent with the extension direction of the first adjusting rod 14. The movable fixed bracket 4 is disposed on the track 41 and can move along the axial direction of the track 41. Multiple movable fixed brackets 4 are included, and the multiple movable fixed brackets 4 are respectively connected to the first adjusting rod 14, the second adjusting rod 15 and the third adjusting rod 16. Thus, by moving the movable fixed bracket 4, the first adjusting rod 14, the second adjusting rod 15 and the third adjusting rod 16 can be driven to move along the axial direction, thereby flexibly adjusting the position of the first adjusting rod 14, the second adjusting rod 15 and the third adjusting rod 16 to adapt to the reversing requirements of different positions.

[0046] In an optional embodiment, the paper box conveying mechanism 3 includes a paper box conveying assembly and a paper box conveying frame; wherein, the paper box conveying assembly is disposed on the paper box conveying frame, one end of the paper box conveying frame is connected to the other end of the inclined surface 21, and the end of the paper box conveying frame connected to the inclined surface 21 is at the same height as the conveying surface in the paper box conveying frame.

[0047] In this embodiment, the paper box conveying assembly is used to convey the paper box 5, and the paper box conveying frame conveys and adjusts the height of the paper box 5. Thus, the paper box conveying assembly and the paper box conveying frame can be combined to realize the conveying operation of the paper box 5.

[0048] In one specific implementation, such as Figure 2 and Figure 3As shown, the paper box conveying frame includes a second conveyor belt support 31, a second conveyor belt drive 32, and a second conveyor belt 33. Both the second conveyor belt drive 32 and the second conveyor belt 33 are mounted on the second conveyor belt support 31, with the second conveyor belt drive 32 positioned on one side of the second conveyor belt 33. The second conveyor belt support 31 includes a second conveyor belt support structure 311 and multiple second height adjustment members 312. The second conveyor belt support structure 311 is mounted on the multiple second height adjustment members 312, and the multiple second height adjustment members 312 are respectively positioned around the second conveyor belt support structure 311. The multiple second height adjustment members 312 can adjust the height of the second conveyor belt 33.

[0049] Specifically, the second conveyor belt support 31 is used to support the second conveyor belt 33 and adjust the height of the second conveyor belt 33. In one embodiment, the second conveyor belt support 31 includes a second conveyor belt support structure 311 and a plurality of second height adjustment members 312. The second conveyor belt support structure 311 is used to support the second conveyor belt 33, and the second height adjustment members 312 are used to adjust the height of the second conveyor belt 33. This allows a height difference to be formed between the first conveyor belt 13 in the reversing conveyor mechanism 1 and the second conveyor belt 33 in the paper box conveying mechanism 3, so that the flipping mechanism 2 can be tilted between the reversing conveyor mechanism 1 and the paper box conveying mechanism 3.

[0050] In practical applications, the second conveyor belt support structure 311 is connected to the support ends of multiple second height adjustment components 312 respectively. The second conveyor belt drive component 32 and the second conveyor belt 33 are both mounted on the second conveyor belt support structure 311. The second conveyor belt drive component 32 is used to drive the second conveyor belt 33. Specifically, the second conveyor belt drive component 32 can adjust the running speed of the second conveyor belt 33 and adjust the tension of the second conveyor belt 33.

[0051] Specifically, the second conveyor belt 33 can be a PU polyurethane textured conveyor belt.

[0052] In one specific implementation, such as Figure 1As shown, the second conveyor belt drive component 32 includes a second drive motor 321, a second transmission roller 322, a second return roller 323, a second motor speed regulator 324, and a second return roller tensioning mechanism 325. The second drive motor 321, the second transmission roller 322, the second return roller 323, the second motor speed regulator 324, and the second return roller tensioning mechanism 325 are all mounted on the second conveyor belt support structure 311. The second transmission roller 322, the second return roller 323, and the second return roller tensioning mechanism 325 are all connected to the drive end of the second drive motor 321. The second motor speed regulator 324 can adjust the running speed of the second drive motor 321. The second return roller tensioning mechanism 325 is used to adjust the tension of the second conveyor belt 33 through the second return roller 323.

[0053] Specifically, the second drive motor 321 provides power to the second transmission roller 322 and the second return roller 323. The second transmission roller 322 and the second return roller 323 drive the second conveyor belt 33. The second motor speed controller 324 can adjust the running speed of the second drive motor 321, thereby adjusting the speed of the second conveyor belt 33.

[0054] In one specific implementation, such as Figure 2 As shown, the paper box conveying assembly includes a fourth adjusting rod 34, a fifth adjusting rod 35, and a conveying track assembly. The conveying track assembly includes a first conveying track 36 and a second conveying track 37 arranged opposite to each other. The connecting end of the fourth adjusting rod 34 is located on one side of the second conveyor belt support structure 311, and the connecting end of the fifth adjusting rod 35 is located on the other side of the second conveyor belt support structure 311. Both the first conveying track 36 and the second conveying track 37 extend along the axial direction of the second conveyor belt support structure 311. The adjusting end of the fourth adjusting rod 34 is connected to the first conveying track 36, and the adjusting end of the fifth adjusting rod 35 is connected to the second conveying track 37. The first conveying track 36 and the second conveying track 37 form a second transmission channel.

[0055] Specifically, the fourth adjusting rod 34 is used to adjust the position of the first conveying track 36, and the fifth adjusting rod 35 is used to adjust the position of the second conveying track 37. By adjusting the first conveying track 36 with the fourth adjusting rod 34 and the second conveying track 37 with the fifth adjusting rod 35, a second conveying channel can be formed between the first conveying track 36 and the second conveying track 37. The width of the second conveying channel is slightly larger than the length of the cardboard box 5. In actual applications, the width of the first conveying channel is equal to the width of the second conveying channel, so that the center point of the flipping assist spring 23 is located on the center line of the second conveying channel, thereby improving the accuracy of the cardboard box conveying mechanism 3 in conveying the cardboard box 5.

[0056] In practical applications, such as Figure 2 As shown, there are two fourth adjusting rods 34 and two fifth adjusting rods 35, which can improve the stability of the first conveying track 36 and the second conveying track 37.

[0057] In one specific embodiment, the second conveyor belt support structure 311 is further provided with a movable fixed bracket 4 and a track 41. The extension direction of the track 41 is consistent with the axial direction of the second conveyor belt support structure 311, that is, the extension direction of the track 41 is consistent with the extension direction of the fourth adjusting rod 34. The movable fixed bracket 4 is disposed on the track 41 and can move along the axial direction of the track 41. Multiple movable fixed brackets 4 are included, and the multiple movable fixed brackets 4 are respectively connected to the fourth adjusting rod 34 and the fifth adjusting rod 35. Thus, by moving the movable fixed bracket 4, the fourth adjusting rod 34 and the fifth adjusting rod 35 can be driven to move along the axial direction, thereby flexibly adjusting the position of the fourth adjusting rod 34 and the fifth adjusting rod 35 to adapt to the conveying stability requirements of different positions.

[0058] The above embodiments of this application have the following beneficial effects: This application provides a reversing conveyor mechanism, a flipping mechanism, and a paper box conveying mechanism. The flipping mechanism is inclined between the reversing conveyor mechanism and the paper box conveying mechanism, and the connection between the flipping mechanism and the reversing conveyor mechanism is higher than the connection between the flipping mechanism and the paper box conveying mechanism. The flipping mechanism includes an inclined surface and a flipping blocking shaft. One end of the inclined surface is connected to the reversing conveyor mechanism, and the other end of the inclined surface is connected to the paper box conveying mechanism. The flipping blocking shaft is located at the connection between the inclined surface and the paper box conveying mechanism, and the end of the inclined surface connected to the reversing conveyor mechanism is lower than the conveying surface in the reversing conveyor mechanism. Thus, the technical solution provided by this application can realize the automated operation of paper box reversing and flipping, reduce the human error rate, and improve the operating efficiency of reversing and flipping.
