[0034] Combine Figures 1 to 5 As shown, the utility model discloses a cardboard longitudinal pressing mechanism, comprising:

[0035] The transfer platform 100 comprises a support platform 110 and a conveying component 120 . The support platform 110 is used to carry cardboard, and the conveying component 120 is used to convey cardboard.

[0036] A plurality of wire pressing units 210, each of which includes a longitudinal pressing blade 211 and a lifting drive component 212, wherein the lifting drive component 212 drives the longitudinal pressing blade 211 to move up and down; the longitudinal pressing blade 211 is located above the support platform 110;

[0037] The knife comb 220 is mounted on the support platform 110 and is located directly below the longitudinal pressing blade 211. The knife comb 220 is composed of a plurality of strip rods arranged at intervals, and each of the strip rods is elastic. The extension direction of the strip rods is the same as the length direction of the press line of the cardboard. There is an empty space below the strip rods, and the empty space is used to provide conditions for the strip rods to deform downward.

[0038] The beneficial effects of the utility model are:

[0039] The cardboard longitudinal pressing mechanism of the present invention is applied to a carton forming machine. A knife comb 220 replaces the existing conveyor shaft to serve as a supporting component. The knife comb 220 and the longitudinal pressing knife are in elastic contact, so the pressing knife is unlikely to damage the knife comb 220. The knife comb 220 has a long service life and is more convenient to replace than the conveyor shaft. Specifically, the knife comb 220 is set directly below the longitudinal pressing blade 211, and the cardboard is conveyed forward by the conveying component 120. When the cardboard reaches directly below the longitudinal pressing blade 211, the lifting drive component 212 drives the longitudinal pressing blade 211 to descend, so that the longitudinal pressing blade 211 presses the moving cardboard into a line. When the longitudinal pressing blade 211 presses the cardboard, the longitudinal pressing blade 211 will act on the knife comb 220, and the strip rod of the knife comb 220 will be deformed, for example, the strip rod will deform downward and / or deform to both sides. After the longitudinal pressing blade 211 rises and resets and no longer acts on the knife comb 220, the strip rod will return to its original state.

[0040] Furthermore, the support platform 110 has multiple hollowed-out locations spaced apart from each other; the conveying member 120 comprises multiple rollers 121, each of which is disposed at each of the hollowed-out locations. The tops of the rollers 121 are higher than or equal to the surface of the support platform 110, and the paperboard is moved by the rotation of the rollers 121. The rollers 121 may be motorized rollers or driven by an external motor.

[0041] Furthermore, when the longitudinal pressing knife is pressing and shaping the cardboard, the cardboard may warp. When the cardboard is greatly warped, the contact area between the cardboard and the conveying component 120 will be reduced, and the conveying component 120 cannot ensure the stable conveying of the cardboard. Therefore, in order to avoid the cardboard from being greatly warped and affecting the conveying of the cardboard, the cardboard longitudinal pressing mechanism further includes a limit plate 230, and the limit plate 230 has a height limiting portion 231. The height limiting portion 231 is located above the knife comb 220 and is spaced apart from the knife comb 220. , the spacing distance is greater than the thickness of the cardboard so that the cardboard can pass through; when the lifting drive component 212 drives the longitudinal pressing blade 211 close to the knife comb 220, the height limiting portion 231 is located on one side of the longitudinal pressing blade 211 and is arranged close to the longitudinal pressing blade 211; the height of the cardboard is limited by the height limiting portion 231, and the height limiting portion 231 is close to the longitudinal pressing blade 211, that is, close to the pressing line position, close to the starting position of the cardboard warping, thereby avoiding large-scale warping of the cardboard and ensuring the stability of cardboard transportation.

[0042] Furthermore, since all cardboards are not necessarily completely straight, their front ends may be tilted. Therefore, in order to ensure that the cardboard can pass through the height limiting portion 231, the limiting plate 230 is provided with a guiding inclined portion 232, one end of which is connected to the height limiting portion 231; the guiding inclined portion 232 is inclined from top to bottom along the conveying direction of the cardboard to increase the entrance of the cardboard before passing through the height limiting portion 231, so that even if the front end of the cardboard is tilted, it can pass through the height limiting portion 231.

[0043] Furthermore, since cardboard has various sizes and specifications, cardboards of different sizes require different positions for longitudinal pressing. In order to make the cardboard longitudinal pressing mechanism suitable for cardboards of various sizes, the cardboard longitudinal pressing mechanism also includes a transverse driving component, and the transverse driving component includes a crossbeam 241, a transverse guide rail 242 and a transverse rack 243. The crossbeam 241 is installed above the transfer platform 100, and the transverse guide rail 242 and the transverse rack 243 are respectively installed on the crossbeam 241; the lifting driving component 212 includes a mounting bracket 2121, a motor 2122 and a gear. The mounting bracket 2121 is slidably set on the transverse guide rail 242 through a slider, and the motor 2122 is fixedly installed on the mounting bracket 2121. The output end of the motor 2122 is fixedly connected to the gear, and the gear is meshed with the transverse rack 243. A motor 2122 is independently configured at each longitudinal pressing blade 211, and the longitudinal pressing blade 211 is driven to move laterally along the length direction of the beam 241 through the transmission cooperation of the motor 2122, the gear and the transverse rack 243, thereby changing the position of the longitudinal pressing blade 211. According to different specifications of cardboard, the longitudinal pressing blade 211 can be moved to the corresponding position, so that the cardboard longitudinal pressing mechanism is suitable for the production of cardboards of various specifications, effectively improving the versatility of the cardboard longitudinal pressing mechanism and saving manufacturing costs.

[0044] Furthermore, the limiting plate 230 is installed on the mounting bracket 2121 so that the limiting plate 230 and the longitudinal pressing blade 211 move laterally synchronously, so that the lateral relative position of the limiting plate 230 and the longitudinal pressing blade 211 remains unchanged. In this way, when the position of the limiting plate 230 is adjusted differently, the height limiting portion 231 remains close to the longitudinal pressing blade 211, that is, close to the pressing line position, close to the starting position of the cardboard warping, thereby avoiding large-scale warping of the cardboard and ensuring the stability of cardboard transportation.

[0045] Furthermore, the lifting drive component 212 is provided with a fixed arm 2125, a cantilever 2126 and a cylinder 2124. The fixed arm 2125 is installed at the bottom of the mounting carrier 2121. The cylinder 2124 is installed at the bottom of the mounting carrier 2121 through a cylinder leg 2127. The longitudinal pressing blade 211 is installed on the fixed arm 2125 through the cantilever 2126. The cylinder 2124 is used to drive the cantilever 2126 to swing relative to the fixed arm 2125 to drive the longitudinal pressing blade 211 to move up and down.

[0046] Furthermore, the outer contour of the longitudinal pressing blade 211 is circular and rotatable, so that when the longitudinal pressing blade 211 presses the cardboard, the blade can rotate to avoid the longitudinal pressing blade 211 being used for pressing only a part of the position, effectively extending the service life of the longitudinal pressing blade 211.

[0047] Furthermore, in order to realize the rotation of the longitudinal pressing blade 211, the paperboard longitudinal pressing mechanism also includes a longitudinal pressing blade 211 rotating component to drive the longitudinal pressing blade 211 to rotate; the longitudinal pressing blade 211 rotating component is provided with a driving motor 2122, a polygonal driving shaft 251, a sleeve 252, a bearing 253, a driving wheel 254, a driven wheel 255 and a synchronous belt 256, wherein the driving motor 2122 is driven and connected to the polygonal driving shaft 251, and the polygonal driving shaft 251 is sequentially provided in a plurality of the fixed arms 2125, and each of the fixed arms 2125 and the driving shaft is sequentially provided with the The shaft sleeve 252 and the bearing 253; the driving wheel 254 is sleeved on the shaft sleeve 252 and fixedly connected to the shaft sleeve 252, the driving wheel 254 is staggered with the fixed arm 2125, and the driving wheel 254 is transmission-connected to the driven wheel 255 through the synchronous belt 256; the driven wheel 255 is fixedly connected to the longitudinal pressing blade 211. The utility model drives the rotation of multiple longitudinal pressing blades 211 at the same time through the polygonal driving shaft 251, so that the rotation speeds of multiple longitudinal pressing blades 211 are consistent, and the tangential forces formed on the cardboard due to the inconsistent rotation speeds of the longitudinal pressing blades 211 will not be different, which will cause the cardboard to deflect during the longitudinal pressing process. It should be noted that the shaft sleeve 252 is provided to allow the fixed arm 2125 to move laterally, so that the longitudinal pressure blade 211 can adjust its position laterally, and the shaft sleeve 252 can drive the driving wheel 254 to rotate; the bearing 253 is provided to ensure that the rotation of the polygonal drive shaft 251 does not affect the movement of the fixed arm 2125, so that the rotation of the polygonal drive shaft 251 and the lateral movement of the fixed arm 2125 can be independent of each other.

[0048] The utility model also discloses a carton forming machine, which comprises the cardboard longitudinal pressing mechanism described above.

[0049] It should be noted that the arrow direction not explained in the drawings is the conveying direction of the cardboard, and the longitudinal direction mentioned in the present invention is consistent with the conveying direction of the cardboard.

[0050] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
