Abstract
Description
Technical Field
[0001] The utility model relates to the field of carton bottom sealing, in particular to a limiting mechanism for a carton bottom sealing device and a carton bottom sealing device. Background Art
[0002] After the whole bag of tissue paper is packed, it needs to be put into cartons, so it is accompanied by the carton unfolding and bottom sealing process; the unfolding process is to unfold the folded carton into a flat shape (because the purchased cartons are usually folded into a flat shape in order to reduce the transportation space and storage space occupied by a single carton) to form a rectangular tube, and then enter the bottom sealing process; the bottom sealing process uses a bottom sealing device, which is to bend the folded edges at the bottom of the carton and align them, and use glue to align and fix them, so as to achieve bottom sealing.
[0003] In the carton bottom sealing device, a folding mechanism is arranged at the bottom, which is a scissor type or a push type, and can fold the folded edge of the bottom of the carton toward the vertical middle plane of the carton; there are conveying devices on both sides of the carton bottom sealing device, which can move the carton; along the movement direction of the carton, at the downstream position of the folding mechanism, there is a sealing mechanism in the carton bottom sealing device, and the packaging device has a roller, and the roller has a tape, which is tightly attached to the two folded edges at the same time, so that the two bottom folded edges are fixed by the tape to complete the bottom sealing. It should be noted that in order to ensure the stable bonding between the tape and the folded edge, the sealing mechanism usually has an elastic member directly or indirectly acting on the roller, so that the roller is subjected to an upward force; when the carton passes through the roller, the carton is pressed against the roller, and the roller moves downward, so that the elastic deformation of the elastic member is aggravated, and the elastic force on the roller increases, so that it is tightly attached to the folded edge of the carton, and the elastic force is converted into a force for pressing the tape on the folded edge, thereby improving the stability of the bonding between the tape and the folded edge.
[0004] From the above, it can be seen that the carton will be subjected to an upward force when the bottom is sealed (especially after passing through the sealing mechanism), and the carton's own weight is relatively light, that is, the carton's own weight cannot overcome the upward force on the carton, resulting in failure of the carton bottom sealing (bottom folding edge bending and / or sealing); for this reason, the top of the carton bottom sealing device also has a top limit plate, which can limit the upward movement of the carton when the carton is subjected to an upward force, ensure the effective folding edge bending, and ensure the stability of the bonding between the tape and the folding edge.
[0005] In actual use, the carton is subjected to the combined effect of the top limit plate and the upward force (for example, the elastic force from the roller transmission elastic member), and the cover plates on both sides of the top of the carton and the carton as a whole are prone to deviation, that is, the cover plates on both sides of the top of the carton are prone to bend outward, which makes it impossible for the top limit plate to limit it normally, resulting in unstable carton molding, stuck boxes and other problems, and also affecting the bottom sealing effect of the carton. Therefore, in order to improve the stability of the top limit plate limiting the carton, it is necessary to improve the limiting mechanism of the carton bottom sealing device. Utility Model Content

[0013] Furthermore, one end of the sheet metal part is fixedly connected to the top limit plate, and the other end of the sheet metal part is connected to the side limit plates via an adjustment mechanism, and the adjustment mechanism can adjust the spacing between the side limit plates.
[0014] Furthermore, the adjustment mechanism is a screw, one end of the screw is rotatably connected to the side limit plate, the other end of the screw is threadedly connected to the sheet metal, and the screw is arranged with its axis perpendicular to the vertical direction and the length direction of the side limit plate.
[0015] Furthermore, the number of the sheet metal parts connected to the same side limit plate is at least 2, and they are evenly distributed at the front and rear ends of the top limit plate and the side limit plate.

[0027] Example 1
[0028] like Figure 1-Figure 4As shown, a limiting mechanism for a carton bottom sealing device comprises a support frame fixed on both sides of the carton 1 bottom sealing device, and two top limiting plates 3 and two side limiting plates 4 are fixed on the support frame. The two top limiting plates 3 are arranged in parallel along the length direction, and the spatial position of the top limiting plates 3 is located above the side limiting plates 4, and can be abutted against the four cover plates on the top of the carton 1 (including two side cover plates 11 located on the sides and front and rear cover plates 12 located on the front and rear sides), thereby limiting the top position of the carton 1; the two side limiting plates 4 are respectively located on both sides of the top limiting plate 3, and can fit the top and two side cover plates of the carton 1 to limit the side of the carton 1.
[0029] In this embodiment, by adding side limit plates 4 on both sides, the carton 1 will not be offset, that is, the two side cover plates 11 will not fold outward and the position of the carton 1 will not be offset perpendicular to the direction of movement, thereby ensuring the contact amount between the cover plate and the top limit plate 3, and then ensuring that the top limit plate 3 can stably limit the carton 1, thereby ensuring the bottom sealing effect of the carton 1, ensuring the molding quality of the carton 1, and reducing the risk of carton jamming.
[0030] Example 2
[0031] Based on Example 1, a specific implementation method that can be implemented is further proposed.
[0032] A feasible implementation method is as follows: Figure 1 As shown, the upstream end of the top limiting plate 3 has a first bending section 31 , the bending direction of the first bending section 31 is upward, and the bending degree is less than 90°. The first bending section 31 plays a guiding role, facilitating the carton 1 to enter under the top limiting plate 3 .
[0033] A feasible implementation method is as follows: Figure 2 As shown, the upstream end of the side limiting plate 4 has a second bending section 41, and the corresponding bending directions of the second bending section 41 are respectively toward the outside of the side, and the bending degree is less than 90°.

[0037] Specifically, the support frame also includes a vertically arranged guide rod 8 and a screw rod 7. There are two guide rods 8, which are located on both sides of the screw rod 7. The screw rod 7 is rotatably connected to the device base 2 of the carton 1 bottom sealing device through a bearing. The screw 7 is threadedly connected to the support block 6. The guide rod 8 passes through the support block 6 and is slidably connected to the support block 6. The guide rod 8 limits the support block 6 to rotate with the screw rod 7. The rotation of the screw rod 7 is transformed into the up and down movement of the support block 6 through the threaded connection transmission with the support block 6, thereby realizing the adjustment of the spatial position of the support block 6 in the vertical direction, and further realizing the height adjustment of the top limit plate 3 and the side limit plate.
[0038] It should be noted that the support block 6 is supported by the screw rod 7 in the support frame through the screw rod 7 being threadedly connected to the support block 6 .

[0042] Specifically, one end of the sheet metal part 5 is fixedly connected to the top limiting plate 3 , and the other end of the sheet metal part 5 is connected to the side limiting plate 4 .
[0043] In a feasible implementation manner, the other end of the sheet metal part 5 is connected to the side limit plate 4 via an adjustment mechanism, and the adjustment mechanism can adjust the spacing between the side limit plates 4 to be suitable for cartons 1 of different widths.
