Description

Technical Field

[0001] The invention relates to the technical field of cardboard production, in particular to a cardboard production conveyor. Background Art

[0002] Cardboard, a thick paper product made by pressing multiple layers of cardboard, exhibits high strength and toughness and is commonly used in the manufacture of packaging containers such as cartons and boxes. Conveying is a crucial component of cardboard production, ensuring the efficient and accurate transfer of materials and semi-finished products between different processes. Conveying cardboard to achieve gluing and lamination of multiple layers is a critical step, directly impacting the quality of the finished product.

[0003] However, the following problems still exist in the process of conveying cardboard for gluing and pressing:

[0004] (1) Usually, the gluing and laminating between cardboards is completed layer by layer by gluing and then covering.

The connecting frame 318 is installed at the end away from the support plate 317 with a moving frame 319 slidably connected to the corresponding longitudinal plate 31 back and forth.

[0037] See also Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 The cam 324 is connected to the cam 326 by the spring 327 and the spring 328 is connected to the cam 329, so that the cam 329 has a fixed position, and the cam 329 is abutted against the stopper 321. The corresponding slides 322 are connected with a connecting spring 328 sleeved on the outside of the fixed rod 327. The side of the slide bar 321 close to the corresponding support plate 317 is equipped with an arc-shaped slider 329 that slides horizontally through the slide 322. The arc-shaped slider 329 is perpendicular to the corresponding slide 322. The lower end of the inclined section of the folding plate 311 is equipped with an arc-shaped push block 330 that cooperates with the corresponding arc-shaped slider 329. The lower end of the inclined section of the folding plate 311 is equipped with an arc-shaped support plate 320. The arc-shaped support plate 320 is tilted downward on the side away from the folding plate 311. The arc-shaped slider 329, the arc-shaped push block 330, and the arc-shaped support plate 320 are all concentric with the rotating circular hole.

[0038] See also Figure 3 、 Figure 6 、 Figure 7 and Figure 8 The cam 332 is fixed on the upper end of the support plate 317, and the cam 333 is fixed on the upper end of the support plate 317 to prevent the cam 333 from sliding onto the support plate 317.

[0039] See also Figure 1 、 Figure 2 and Figure 3 A mounting frame 4 installed on the upper end of the base plate 2 is provided above the stacking unit 3, and a solid component located above the stacking unit 3 is provided at the lower end of the mounting frame 4. The solid component includes a pressing plate 41 located below the mounting frame 4, and rectangular plates 411 higher than the columns 331 are installed on the left and right sides of the upper end of the pressing plate 41. Horizontal plates are installed on the left and right sides of the mounting frame 4, and vertical rods 412 connected to the corresponding horizontal plates for sliding up and down are installed on the upper ends of the rectangular plates 411. An auxiliary spring sleeved on the outside of the vertical rods 412 is connected between the upper ends of the vertical rods 412 and the horizontal plates. An electric push rod 413 is installed on the horizontal plate, and a square plate matching the rectangular plate 411 is installed on the lower end of the pushing end of the electric push rod 413.

[0040] See also Figures 1-9When the folding plate 311 is in the state of pressing the movable plate 332 downward, the auxiliary spring is in the compressed state, and the electric push rod 413 is in the extended state. Under the action of the movable plate 332, the vertical spring 333 is in the compressed state, and the downward moving column 334 and the protruding column pass through the avoidance hole on the lower support plate 317 and are placed in the avoidance groove. At this time, there is enough distance between the pressing plate 41 and the uppermost partition component to facilitate the inclined conveyor belt to transport and place cardboard. In addition, at this time, all the folding plates 311 are rotated to a position close to the corresponding longitudinal plate 31, and the arc-shaped push block 330 at the lower end of the inclined section of the folding plate 311 just presses. The corresponding arc-shaped slider 329 and the slide bar 321 compress the telescopic spring 323 along the open groove, and all L-shaped limit plates 312 are in a position close to the corresponding slide plate 322. In addition, since the folding plate 311 is now located close to the corresponding longitudinal plate 31, and the arc-shaped groove 314 slides with the corresponding movable column 316, the movable column 316 at the lower end of the top and middle L-shaped limit plates 312 is now located at the end of the corresponding arc-shaped groove 314. Correspondingly, the L-shaped limit plates 312 at the top and the middle are both close to the bottom L-shaped limit plate 312, and the slide plate 322 compresses the connecting spring 328 along the corresponding fixed rod 327.

[0041] When the existing inclined conveyor belt conveys the first cardboard to the upper end of the bottom plate 2, the cardboard can enter between the L-shaped limit plates 312 in the lowest partition assembly. At this time, the arc-shaped abutment plate 320 at the lower end of the inclined section of the folding plate 311 is just located close to the cardboard, completing the rough positioning of the cardboard. However, the cardboard may not be completely centered, so the L-shaped limit plate 312 can be used to center the cardboard. During this process, the electric push rods 413 on the left and right sides are simultaneously retracted. Under the action of the vertical rod 412 and the auxiliary spring, the rectangular plates 411 on the left and right sides and the pressing plate 41 move upward synchronously, and the movable plate 3 When the folding plate 311 is in the state of being moved up and down, the folding plate 311 of the embodiment of the present invention is put into the state of being moved up and down, and the folding plate 311 of the embodiment of the present invention is put into the state of being moved up and down. When the folding plate 311 is rotated, the movable column 316 and the L-shaped limit plate 312 in the middle are pushed upward by the cooperation between the arc groove 314 and the movable column 316. 1 is composed of a downwardly inclined bending section and a horizontal section, and the shape of the bottom wall of the arc-shaped groove 314 is consistent with the shape of the folding plate 311. Therefore, the moving column 316 will move up and down along the bottom wall of the arc-shaped groove 314). The middle L-shaped limiting plate 312 gradually reaches the upper end of the horizontal section of the lowest folding plate 311. The slide plate 322 can drive the slide bar 321 to move upward along the corresponding fixed rod 327 under the action of the connecting spring 328. At this time, the folding plates 311 in the lowest partition assembly are all located above the first cardboard, and the L-shaped limiting plates 312 in the middle partition assembly are all moved upward accordingly.

[0042] Then, the second paperboard can be transported to the upper end of the folding plate 311 in the lowermost separation assembly in the same way as described above, and the folding plate 311 can support the second paperboard, and then the rectangular plates 411 on the left and right sides can continue to move upward, the moving plate 332 moves upward synchronously with the protruding column, until the protruding column moves upward to disengage the rotating block 313 in the middle, in the process, the L-shaped limiting plate 312 in the middle separation assembly can center the second paperboard in the same way as described above, and the folding plate 311 in the middle separation assembly can be rotated synchronously to the upper end of the second paperboard, and the L-shaped limiting plate 312 in the uppermost separation assembly moves upward accordingly, and the third paperboard can be placed and centered in turn, and the centered paperboard is beneficial to improve the stability and accuracy of the subsequent paperboard in the gluing and pressing process, and under the action of the folding plate 311 in the different separation assemblies, the three paperboards are separated from each other and do not contact each other, but maintain the centered and accurately opposite state, which lays a foundation for the accurate and unbiased bonding between the upper and lower multiple paperboards.

[0043] Please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 , the upper end of the bottom plate 2 is provided with an adjusting assembly for synchronously adjusting the positions of different separation assemblies, the adjusting assembly includes a connecting plate 341, the connecting plate 341 is arranged on the side of the longitudinal plate 31 away from the stacking unit 3 between the two moving frames 319 opposite in front of and behind each other and between the two bottom sliding frames 325 opposite in front of and behind each other, the front and rear sides of the connecting plate 341 are both provided with uniformly arranged insertion holes 342, the moving frame 319 and the bottom sliding frame 325 are both inserted and matched with the corresponding insertion holes 342, the connecting plate 341 located at the lowermost position is slidingly connected with the bottom plate 2, the longitudinally arranged plates 31 uniformly arranged above and below are jointly installed between the two positioning rods 343 distributed in front of and behind each other, the upper end of the bottom plate 2 is provided with positioning holes 344 uniformly arranged on the left and right sides at positions corresponding to the positioning rods 343, and the positioning rod 343 is inserted with the corresponding positioning hole 344.

[0044] Before placing the cardboard, the different partition components can be adjusted to the appropriate position according to the length and width of the cardboard. When the length of the cardboard changes, the corresponding moving frame 319 and the bottom sliding frame 325 can be moved back and forth along the longitudinal plate 31. After the moving frame 319 and the bottom sliding frame 325 are moved to the appropriate position, the insertion rod can be inserted into the corresponding insertion hole 342 to fix the moving frame 319 and the bottom sliding frame 325 on the corresponding longitudinal plate 31. When the moving frame 319 moves, the corresponding L-shaped limit plate 312, the slide plate 322 and the folding plate 311 can be driven to move synchronously through the connecting frame 318, the support plate 317 and the side plate 326. The bottom sliding frame 325 can drive the lowest slide plate 322 and the L-shaped limit plate 312 to move synchronously through the connecting rod 324 to change the The positions of the L-shaped limiting plates 312 and the folding plates 311 in the front-to-back directions in different partitioning components; when the width of the cardboard changes, the longitudinal plates 31 located on the left and right sides of the stacking unit 3 and evenly arranged up and down can be moved left and right along the bottom plate 2, and the corresponding positioning rods 343 move synchronously with the longitudinal plates 31.

In the process of positioning the paperboard by the L-shaped limiting plate 312, the L-shaped limiting plate 312 can rotate relative to the extension end of the bidirectional telescopic rod 345, and when adjusting the positions of the L-shaped limiting plate 312 and the folded plate 311, the bidirectional telescopic rod 345 is correspondingly telescoped, and in the process of moving the L-shaped limiting plate 312 up and down, the elastic telescopic column 352 is synchronously telescoped through the bidirectional telescopic rod 345, and after the three paperboards are all placed, the front support plate 349 can be moved forward by the cylinder 351, the moving rack 348 on the left side is synchronously moved forward along the mounting frame 4, and under the action of the rotating gear 347, the moving rack 348 on the right side can drive the rear support plate 349 to move backward along the mounting frame 4, and the front support plate 349 can drive the corresponding bidirectional telescopic rod 345 to move forward through the elastic telescopic column 352, and under the action of the bidirectional telescopic rod 345, the L-shaped limiting plate 312 in the uppermost separation assembly is synchronously moved, and under the cooperation of the side plate 326, the support plate 317 and the connecting frame 318, the folded plate 311 in the uppermost separation assembly and the middle separation assembly can drive the uppermost paperboard to move forward synchronously, and the post 331, the vertical spring 333, the moving plate 332, the lower moving column 334 and the convex column are synchronously moved with the corresponding support plate 317, the rear support plate 349 can drive the corresponding bidirectional telescopic column to move backward through the elastic telescopic column 352, correspondingly, the L-shaped limiting plate 312 in the middle separation assembly and the folded plate 311 in the lowermost separation assembly can drive the paperboard in the middle to move backward, until the paperboards in the uppermost layer and the middle layer move reversely to the paperboard in the lowermost layer, and the L-shaped limiting plate 312 in the lowermost separation assembly and the paperboard remain in a stationary state, in addition, the moving frame 319 can slide along the longitudinal plate 31 synchronously with the corresponding separation assembly, the connecting plate 341 between the front and rear moving frames 319 is synchronously moved, and the longitudinal plate 31 can provide guiding support for the movement of the separation assembly and the paperboard, ensuring the stability of the separation assembly and the paperboard during the movement.

[0048] S2. After the three cardboard sheets are unfolded, the gluing station uses existing gluing equipment to apply glue to the upper ends of the cardboard sheets located at the rear and middle positions. After gluing is complete, the top and middle dividers are moved back and forth in the reverse order described above, returning them to their initial stacking position. The cardboard sheets move synchronously with the corresponding dividers, and the glued cardboard sheets remain free of contact with adjacent cardboard sheets, ensuring smooth movement and an intact glue layer.

[0049] In the process of moving the top and middle layers of cardboard in opposite directions back and forth, the fixed plate 346 located on the front side will come into conflict with the positive limit plate 353, thereby limiting the movement of the top partition assembly, and the movement of the middle partition assembly is simultaneously restricted. In the process of moving the above two cardboards back and forth, the auxiliary plate 355 can move with the top connecting plate 341 to come into conflict with the side limit plate 356, thereby limiting the relative movement of the two partition assemblies, thereby ensuring the accuracy of the position of the partition assembly and the cardboard during the movement, and ensuring that the three cardboards are always in a stacked and aligned position before and after the movement, thereby improving the subsequent pressing quality. In addition, when the length of the cardboard changes, the positive limit plate 353 can be moved back and forth along the bottom plate 2. After moving to the appropriate position, the rectangular block can be inserted into the corresponding rectangular hole 354 to fix the positive limit plate 353 on the bottom plate 2, ensuring that the positive limit plate 353 can limit the movement of cardboards of different lengths. Since the auxiliary plate 355 is located in the middle of the connecting plate 341, the position of the side limit plate 356 does not need to be changed. When the width of the cardboard changes, the position of the positive limit plate 353 does not need to be adjusted, and because the lateral length of the auxiliary plate 355 is greater than the lateral length of the side limit plate 356, the side limit plate 356 can meet the limiting requirements of the partition components under different width conditions.

[0050] After the bottom and middle layers of the cardboard coated with the adhesive layer are reset, the electric push rod 413 can push the rectangular plate 411 downward through the square plate and press the moving plate 332 downward. The moving plate 332 drives the lower moving column 334 and the boss to move downward along the column 331 by compressing the vertical spring 333. When the lower moving column 334 drives the boss to pass through the uppermost rotating block 313 and the support plate 317, the cooperation between the boss and the spiral groove 335 drives the uppermost rotating block 313 to drive the corresponding folding plate 311 to rotate in the direction close to the longitudinal plate 31, and the uppermost folding plate 3 When the upper portion 311 is rotated away from the cardboard, the arc-shaped push block 330 will contact the corresponding arc-shaped slider 329, so that the uppermost L-shaped limit plate 312 moves along the corresponding opening groove and separates from the cardboard. At this time, the arc-shaped support plate 320 contacts the uppermost cardboard again, and the arc-shaped support plates 320 at different positions can simultaneously implement circumferential limit on the cardboard, while the folding plate 311 in the middle can support the uppermost cardboard. When the downward column 334 drives the protruding column to pass through the rotating block 313 and the support plate 317 in the middle, the folding plate 311 in the middle is synchronously moved towards the direction close to the longitudinal plate 31. When the folding plate 311 rotates to separate from the top cardboard, the corresponding arc-shaped push block 330 does not interfere with the arc-shaped slider 329. At the same time, the uppermost L-shaped limiting plate 312 can move downward with the rotation of the middle folding plate 311. In the limited state, the top cardboard moves downward synchronously to fit the glued cardboard of the middle layer. When the middle folding plate 311 rotates to completely separate from the cardboard, the arc-shaped push block 330 can squeeze the corresponding arc-shaped slide plate 322 to separate the slide bar 321 and the middle L-shaped limiting plate 312 from the cardboard, and the corresponding arc-shaped supporting plate 320 interferes with the cardboard of the middle layer. Afterwards, the downward moving column 334 and the protruding column can continue to be moved downward to pass through the rotating block 313 and the supporting plate 317 below. The top and middle layers of cardboard can be moved downward in the same way until the middle layer of cardboard fits the glued surface of the bottom layer of cardboard. However, it is necessary to keep the L-shaped limiting plate 312 in the bottom partition assembly limiting the cardboard. The three cardboards always maintain a circumferential limiting state under the action of the arc-shaped abutment plate 320 and the L-shaped limiting plate 312, which can prevent the subsequent cardboards from being deflected due to the pressing force, thereby increasing the stability and accuracy of the pressing between the cardboards, and thus improving the composite quality of the cardboards.

[0051] S4. After the three layers of cardboard are initially and accurately bonded together, the rectangular plate 411 and the pressing plate 41 can be further moved downward. At this time, the lowering column 334 and the protruding column can be moved downward into the avoidance groove, and the pressing plate 41 can press down the top layer of cardboard to press and solidify the bonding of the three cardboards. Subsequently, the bottom plate 2, the stacking unit 3 and the bonded cardboards can be transported to the pressing station by driving the conveyor. The existing pressing equipment can apply downward pressure to the pressing plate 41. The pressing plate 41 and the rectangular plate 411 will be separated from the square plate connected to the lower end of the electric push rod 413 under pressure and tightly pressed against the upper end of the cardboard, thereby completing the pressing of the cardboard. Then, the limit of the cardboard on the cardboard by the lowest partition component can be released. Finally, the composite cardboard can be taken out for subsequent processing.
