Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a carton forming machine. Background Art

[0002] Compared to traditional carton production processes, carton forming machines can be used to produce small batches of cartons in a variety of sizes. They offer high production efficiency, requiring only one operator to complete the entire process. Carton forming machines typically include modules for cardboard feeding, slotting, threading, longitudinal creasing, longitudinal slitting, cross-cutting, and perforating.

[0003] First of all, when processing the cardboard, it is necessary to perform longitudinal pressing on the designated position of the cardboard; and when the longitudinal pressing knife presses the cardboard, it will contact the conveying shaft used to convey the cardboard, which will scratch and damage the rubber sleeve on the outer layer of the conveying shaft, making the service life of the rubber sleeve very short; after the rubber sleeve is damaged, it will also affect the pressing effect of the cardboard, and after the rubber sleeve is damaged, the conveying shaft needs to be disassembled to replace the new rubber sleeve, which is troublesome to replace.

[0004] Secondly, when the cardboard is being processed, it is necessary to press the designated position of the cardboard horizontally; and when the horizontal pressing knife presses the cardboard, it will contact the support table used to support the cardboard, which will scratch the support table, and because the support of the support table blocks the horizontal pressing knife's pressing work on the cardboard, the pressing effect of the horizontal pressing knife on the cardboard is weakened.

[0005] Finally, when processing cardboard, it is necessary to punch holes at designated locations on the cardboard. This is often done by first using a punching mechanism to create a hole-shaped contour indentation on the cardboard, but this contour indentation does not separate the hole from the cardboard. The worker then removes the cardboard within the contour indentation. After punching the cardboard, the punching mechanism in the prior art causes the cardboard to cling to the punching die. As the punching die rises, it pulls the cardboard up with it, affecting the cardboard's transport to other modules and disrupting the carton forming machine's production. Summary of the Invention

[0035] The beneficial effects of the utility model are:

[0036] The utility model discloses a carton forming machine, wherein a cardboard longitudinal pressing mechanism, a cardboard transverse pressing mechanism and a cardboard punching mechanism are sequentially arranged on a transfer platform according to a cardboard conveying direction; a knife comb is used to replace an existing conveying shaft to serve as a supporting component for longitudinal pressing, and an open groove is provided below a transverse pressing position, so that the transverse pressing blade presses the cardboard toward the open groove during movement, and the corresponding position of the cardboard is bent into a line toward the open groove, thereby realizing transverse pressing of the cardboard; during the punching process, a paper pressing wheel is kept in cooperation with a roller by a spring to press the cardboard, thereby effectively solving the problem that the cardboard adheres to a punching die and rises with the punching die.

[0037] The utility model discloses a longitudinal line pressing mechanism for cardboard, which uses a knife comb to replace the existing conveyor shaft to serve as a supporting component for longitudinal line pressing. The knife comb and the longitudinal pressing blade are in elastic contact, making it difficult for the pressing blade to damage the knife comb. The knife comb has a long service life and is more convenient to replace than the conveyor shaft. Specifically, the knife comb is arranged directly below the longitudinal pressing blade, and the cardboard is conveyed forward by the conveyor component. When the cardboard reaches directly below the longitudinal pressing blade and reaches the longitudinal line pressing position, the longitudinal pressing blade is driven down by the lifting drive component so that the longitudinal pressing blade presses the moving cardboard into a line. When the longitudinal pressing blade presses the cardboard, the longitudinal pressing blade acts on the knife comb, causing the strip rod of the knife comb to deform, for example, the strip rod may deform downward and / or to the sides. After the longitudinal pressing blade rises and resets and no longer acts on the knife comb, the strip rod returns to its original state.

[0038] The utility model discloses a cardboard transverse pressing structure, wherein the cardboard on the support platform is conveyed forward by the conveying component, and when the cardboard reaches the transverse pressing position, the conveying component stops moving the cardboard, and the transverse pressing blade is staggered with the cardboard; then the transverse driving component drives the transverse pressing blade to move transversely, and during the movement, the transverse pressing blade presses the cardboard toward the open slot, so that the corresponding position of the cardboard is bent into a line toward the open slot, thereby realizing the transverse pressing of the cardboard, and the pressing line is smooth, solving the problem that the support platform blocks the transverse pressing knife from pressing the cardboard, and improving the quality and aesthetics of the carton.

[0039] The cardboard punching mechanism of the present invention presses the cardboard through the cooperation of the paper pressing wheel and the roller during the punching process, effectively solving the problem that the cardboard adheres to the punching die and rises with the punching die. Specifically, the driving component drives the two rollers to rotate until the cardboard passes between the paper pressing wheel and the roller and reaches the punching position, and the two rollers stop rotating. When the paper wheel passes between the paper pressing wheel and the roller, the spring is subjected to a compression force, so that the paper pressing wheel keeps pressing the cardboard. After the roller stops rotating, the pressure of the paper pressing wheel on the cardboard can fix the position of the cardboard. Then the punching cylinder drives the punching die to descend to perform a punching operation on the cardboard on the punching table, thereby realizing the punching operation of the cardboard. After the punching is completed, the driving component drives the two rollers to rotate to transport the cardboard forward, so that the cardboard leaves the punching table.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] Combine Figures 1 to 9 As shown, the utility model discloses a carton forming machine, comprising:

[0056] 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. The support platform 110 has a transversely arranged open slot 111.

[0057] The transfer platform 100 is provided with a cardboard longitudinal pressing mechanism 200, a cardboard transverse pressing mechanism 300, and a cardboard punching mechanism 400 in sequence according to the cardboard conveying direction;

[0058] The cardboard longitudinal pressing mechanism 200 includes a plurality of pressing units 210, each of which includes a longitudinal pressing blade 211 and a lifting drive component 212. The lifting drive component drives the longitudinal pressing blade 211 to move up and down. The longitudinal pressing blade 211 is located above the support platform 110. A knife comb 220 is installed 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 extending direction of the strip rods is the same as the length direction of the cardboard pressing line. There is an empty space below the strip rods.

[0059] The cardboard transverse pressing mechanism 300 includes a transverse pressing blade 310 and a second transverse driving component 320, wherein the second transverse driving component 320 is used to drive the transverse pressing blade 310 to perform transverse reciprocating linear motion; the bottom end of the transverse pressing blade 310 is inserted into the opening slot 111;

[0060] The cardboard punching mechanism 400 includes a punching unit, which includes a punching platform 410 and a punching component; the punching component includes a support frame 421, a punching cylinder 422 and a punching die 423, the punching die 423 is located above the punching platform 410, and the punching cylinder 422 is fixed to the support frame 421 to drive the punching die 423 to move up and down;

[0061] A conveying unit, comprising a driving component and two rollers 440 , the two rollers 440 being located on either side of the punching table 410 , with the tops of the rollers 440 being flush with the upper surface of the punching table 410 ;

[0062] Two paper pressing units are respectively located above the two rollers 440. The paper pressing units include a paper pressing wheel 450 and a cantilever arm 460. The cantilever arm 460 is connected to the support frame 421 through a spring 490 so that the cantilever arm 460 can move in a vertical direction relative to the support frame 421. The paper pressing wheel 450 is rotatably set on the cantilever arm 460, and the paper pressing wheel 450 is against the roller 440.

[0063] Further, combined with Figures 1 to 4 As shown, the support platform 110 has multiple hollowed-out locations spaced apart from each other; the conveying member 120 has multiple rollers 121, which are respectively disposed at the multiple 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 can be motorized rollers or driven by an external motor.

[0064] Further, combined with Figures 1 to 8 As shown, the outer contours of the transverse pressing blade 310 and the longitudinal pressing blade 211 are circular and rotatable; in this way, when the transverse pressing blade 310 and the longitudinal pressing blade 211 are pressing the cardboard, the blades can rotate, avoiding that only a local position of the transverse pressing blade 310 and the longitudinal pressing blade 211 is used for pressing, effectively extending the service life of the transverse pressing blade 310 and the longitudinal pressing blade 211.

[0065] Further, combined with Figures 1 to 4 As shown, 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 200 further includes a limiting plate 230, and the limiting plate 230 has a height limiting portion 231. The height limiting portion 231 is located above the knife comb 220 and has a spacing distance between it and the knife comb 220, and the spacing distance is greater than the thickness of the cardboard; when the lifting drive component drives the longitudinal pressing blade 211 to approach the knife comb 220, the height limiting portion 231 is located on a horizontal 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 position, close to the starting position of the cardboard warping, thereby avoiding the cardboard from being greatly warped and ensuring the stability of cardboard transportation;

[0066] Since all cardboards are not necessarily completely straight and their front ends may be tilted, 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 the cardboard can pass through the height limiting portion 231 even if the front end of the cardboard is tilted.

[0067] Furthermore, since cardboards have various sizes and specifications, different sizes of cardboards require different longitudinal pressing positions. In order to make the cardboard longitudinal pressing structure applicable to cardboards of various sizes, the cardboard longitudinal pressing mechanism 200 further includes a first transverse driving component, which includes a first transverse beam 241, a first transverse guide rail 242, and a first transverse rack 243. The first transverse beam 241 is installed above the transfer platform 100, and the first transverse guide rail 242 and the first transverse rack 243 are respectively installed on the first transverse beam 241.

[0068] The lifting drive component includes a mounting bracket 2121, a transverse motor 2122, and a gear. The mounting bracket 2121 is provided with a limit plate 230. The mounting bracket 2121 is slidably mounted on the transverse guide rail via a first slider. The transverse motor 2122 is fixedly mounted on the mounting bracket 2121. The output end of the transverse motor 2122 is fixedly connected to the gear, which is meshed with the transverse rack. A transverse motor 2122 is independently configured at each longitudinal pressing blade 211. The transverse motor 2122, the gear, and the first transverse rack 243 drive the longitudinal pressing blade 211 to move transversely along the length direction of the first crossbeam 241, thereby changing the position of the longitudinal pressing blade 211. The longitudinal pressing blade 211 can be moved to the corresponding position according to different specifications of cardboard, making the cardboard longitudinal pressing line structure suitable for the production of various specifications of cardboard, effectively improving the versatility of the cardboard longitudinal pressing line structure.

[0069] The lifting drive component includes a fixed arm 2125, a cantilever arm 2126, and a lifting cylinder 2124. The fixed arm is mounted on the bottom of the mounting bracket 2121. The cylinder is mounted on the bottom of the mounting bracket 2121 via a cylinder bracket. The longitudinal pressing blade 211 is mounted on the fixed arm 2125 via the cantilever arm 2126. The cylinder is used to drive the cantilever arm 2126 to swing relative to the fixed arm 2125, thereby driving the longitudinal pressing blade 211 to move up and down. It should be noted that the cylinder bracket is a common component used to mount the cylinder.

[0070] Further, combined with Figure 1 、 Figures 5 to 8 As shown, the second transverse drive component 320 includes a second transverse beam 321, a second drive motor 322, two transmission wheels 323, a synchronous belt 324, a second transverse guide rail 325, a second slider 326, an intermediate carrier 327 and a clamping plate 328; the two transmission wheels 323 are rotatably mounted on the second transverse beam 321 through a second bracket 341, and the two transmission wheels 323 are transmission-connected through the synchronous belt 324, the second drive motor 322 is fixedly mounted on one of the second brackets 341 and is drivingly connected to the transmission wheel 323 on the second bracket 341, the second transverse guide rail 325 is mounted on the second transverse beam 321, the second transverse guide rail 325 is parallel to the synchronous belt 324, the intermediate carrier 327 is mounted on the second slider 326, one side of the synchronous belt 324 is against the intermediate carrier 327, and the clamping plate 328 is used to fixedly connect the synchronous belt 324 to the intermediate carrier 327; the intermediate carrier 327 is connected to the transverse pressure blade 310. The second driving motor 322 drives the transmission wheel 323 to rotate, and the rotation of the transmission wheel 323 drives the movement of the synchronous belt 324, thereby driving the horizontal pressure blade 310 on the intermediate carrier 327 to move horizontally.

[0071] Furthermore, in order to enable the transverse pressure blade 310 to rotate while moving transversely, the second transverse driving component 320 also includes a second transverse rack 329, which is mounted on the second transverse beam 321 and is arranged parallel to the second transverse guide rail 325; the intermediate carrier 327 includes a first carrier plate and a second carrier plate, the first carrier plate is fixedly connected to the second slider 326, the second carrier plate is vertically arranged on the outer side of the first carrier plate, and a gear transmission component is provided on the second carrier plate, the gear transmission component is transmission-connected to the second transverse rack 329, and the transverse pressure blade 310 is fixedly connected to the gear transmission component; due to the synchronous belt 3 When moving, the intermediate carrier 327 is driven to move, so that the gear transmission component located on the second carrier plate moves laterally. When the gear transmission component moves laterally, it engages with the second transverse rack 329 for transmission, and the gear transmission component rotates, thereby driving the transverse pressing blade 310 to rotate. That is, the transverse pressing blade 310 rotates while relying on the second transverse driving component 320 to drive the transverse pressing blade 310 to move laterally, rather than simply relying on the contact friction with the cardboard to rotate. In this way, the friction between the transverse pressing blade 310 and the cardboard can be reduced, the service life of the transverse pressing blade 310 can be effectively extended, and the damage to the cardboard caused by the friction with the transverse pressing blade 310 can be avoided, thereby effectively improving the quality of the cardboard.

[0072] The gear transmission component includes a first gear 330 and a second gear 331. The first gear 330 is meshed with the second transverse rack 329 for transmission. The first gear 330 and the second gear 331 are transmitted in a flat meshing manner. The transverse pressure blade 310 is fixedly connected to the second gear 331. The diameter of the first gear 330 is greater than the diameter of the second gear 331; that is, the first gear 330 is a large gear and the second gear 331 is a small gear. The large gear drives the small gear to rotate, thereby increasing the rotation speed of the small gear, and then increasing the rotation speed of the transverse pressure blade 310 fixedly connected to the small gear, thereby effectively reducing the friction between the transverse pressure blade 310 and the cardboard, and extending the service life of the transverse pressure blade 310.

[0073] Furthermore, the cardboard transverse pressing mechanism 300 also includes a paper discharge unit, which includes a plurality of roller groups 340 distributed in the transverse direction. The roller group 340 includes a bracket 341, a connecting shaft 342 and a plurality of rollers 343. The bracket 341 is installed on the crossbeam, and the connecting shaft 342 is provided on both sides of the bracket 341 and can be lifted and lowered relative to the bracket 341. The roller 343 is rotatably installed on the connecting shaft 342 through a bearing; the plurality of rollers 343 press on the cardboard to reduce the amplitude of the cardboard being tilted upward due to the pressing line, so that the bottom plate of the cardboard maintains contact with the conveying component 120 at the transfer platform 100, thereby ensuring the conveyance of the cardboard.

[0074] The bracket 341 has strip-shaped slots 3411 on both sides, which are arranged obliquely or vertically. The two ends of the connecting shaft 342 are respectively inserted into the two strip-shaped slots 3411. When the connecting shaft 342 abuts the bottom sides of the strip-shaped slots 3411, the distance between the roller 343 and the transfer platform 100 is less than the thickness of the cardboard. Because the arrangement of the strip-shaped slots 3411 provides conditions for the roller 343 to move upward, when the cardboard passes by the roller 343, the cardboard pushes the roller 343 up. Under the action of gravity, the roller 343 maintains pressure on the cardboard, ensuring that the bottom surface of the cardboard maintains contact with the conveying member 120 on the transfer platform 100. Furthermore, the paper discharge unit can be used with a variety of cardboard thicknesses, the difference being that the height to which the roller 343 is lifted varies depending on the thickness of the cardboard. This improves the versatility of the cardboard transverse pressing structure.

[0075] Furthermore, the drive assembly includes a drive shaft 431 and a third drive motor 432. The drive shaft 431 passes through the bottom of the punching table 410 and is connected to the two rollers 440. The third drive motor 432 is connected to the drive shaft 431 to drive the two rollers 440 to rotate synchronously, thereby ensuring the stable transportation of the cardboard and avoiding the two rollers 343 from rotating at different speeds, resulting in uneven force on the cardboard and causing deflection.

[0076] Further, combined with Figure 9 As shown, cardboards of different specifications may have different punching positions. In order to make the cardboard punching structure applicable to cardboards of various specifications, the cardboard punching mechanism 400 includes a first transverse moving component 470 and a second transverse moving component;

[0077] The first transverse moving member 470 is connected to the support frame 421 so that the support frame 421 can move transversely;

[0078] The second transverse moving component is connected to the punching platform 410 and the two rollers 440 so that the punching platform 410 and the two rollers 440 can move transversely, so that the transverse positions of the punching platform 410 and the two rollers 343 can be adjusted according to different specifications of cardboards.

[0079] Furthermore, the first transverse moving component 470 includes a third transverse beam 471 and a third slide rail 472. The third slide rail 472 is transversely arranged on the third transverse beam 471. The support frame 421 is connected to the third slide rail 472 via a third slider, so that the support frame 421 can move transversely.

[0080] A laterally extending scale is provided on the third crossbeam 471; a pointer 473 is fixed on the support frame 421, and the pointer 473 is close to and points to the scale; the staff can make corresponding marks on the scale according to different specifications of cardboard, and the mark must be aligned with the pointer 473, so that when changing production, the staff can quickly move the punching die 423 to the corresponding position. After the punching die 423 is moved into place, the punching table 410 and the roller 343 are moved to the corresponding positions with reference to the position of the punching die 423, which enables fast and convenient production changes.

[0081] The second transverse moving member further includes a fourth slide rail 481, which is arranged transversely on the support platform 110. The punching platform 410 is connected to the fourth slide rail 481 via a fourth slider 482. Supports 484 are connected to opposite sides of the two rollers 440, and the supports 484 are connected to the fourth slide rail 481 via a fifth slider 483. The cross-section of the drive shaft 431 is polygonal. In this way, the drive shaft 431 can transmit power to rotate the rollers 440 while also enabling the rollers 440 to move transversely along the drive shaft 431. The drive shaft 431 is preferably a hexagonal shaft.

[0082] It should be noted that corresponding positioning holes can be set on the third crossbeam 471 and the support platform 110 according to different specifications of cardboards, and pins can be set on the support frame 421, the support 484 and the punching platform 410 to realize the positioning and fixation of the punching die 423, the roller 440 and the punching platform 410 by plugging the pins into the positioning holes.

[0083] Furthermore, a rubber plate 411 is provided on the upper surface of the punching table 410. When the punching die 423 punches the cardboard, the punching die 423 presses the rubber plate, effectively avoiding direct contact between the punching die 423 and the punching table 410, and effectively extending the service life of the punching die 423 and the punching table 410.

[0084] Furthermore, the axial length of the roller 440 is greater than the axial length of the paper pressing wheel 450 to avoid slipping.

[0085] The beneficial effects of the utility model are:

[0086] The utility model discloses a carton forming machine, on which a cardboard longitudinal pressing mechanism 200, a cardboard transverse pressing mechanism 300, and a cardboard punching mechanism 400 are sequentially arranged on a transfer platform 100 according to the cardboard conveying direction; a knife comb 220 is used to replace the existing conveying shaft to serve as a supporting component for longitudinal pressing, and an open groove 111 is provided below the transverse pressing position, so that the transverse pressing blade 310 presses the cardboard toward the open groove 111 during movement, and the corresponding position of the cardboard is bent into a line toward the open groove 111, thereby realizing the transverse pressing of the cardboard; during the punching process, the spring 490 is used to keep the paper pressing wheel 450 in cooperation with the roller 343 to press the cardboard, thereby effectively solving the problem that the cardboard adheres to the punching die 423 and rises with the punching die 423.

[0087] The cardboard longitudinal pressing mechanism 200 of the present invention uses a knife comb 220 to replace the existing conveyor shaft to serve as a supporting component during longitudinal pressing. The knife comb 220 and the longitudinal pressing knife are in elastic contact, and 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 and reaches the longitudinal pressing line position, 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.

[0088] The cardboard transverse pressing structure of the present invention is as follows: the conveying component 120 conveys the cardboard on the support platform 110 forward; when the cardboard reaches the transverse pressing position, the conveying component 120 stops moving the cardboard, and the transverse pressing blade 310 is staggered with the cardboard; then the transverse driving component drives the transverse pressing blade 310 to move transversely, and the transverse pressing blade 310 presses the cardboard toward the open groove 111 during the movement, so that the corresponding position of the cardboard is bent into a line toward the open groove 111, thereby achieving transverse pressing of the cardboard and smooth pressing, solving the problem that the support platform 110 blocks the transverse pressing blade from pressing the cardboard, and improving the quality and aesthetics of the carton.

[0089] The cardboard punching mechanism 400 of the present invention presses the cardboard during the punching process by cooperating with the pressing wheel 450 and the roller 343, thereby effectively solving the problem that the cardboard adheres to the punching die 423 and rises along with the punching die 423. Specifically, the driving component drives the two rollers 343 to rotate until the cardboard passes between the pressing wheel 450 and the roller 343 and reaches the punching position. The two rollers 343 stop rotating, and when the cardboard passes through the pressing wheel 450 and the roller 343, the two rollers 343 stop rotating. When the rollers 343 are between the two sides, the spring 490 is compressed, so the paper pressing wheel 450 will continue to press the cardboard. After the rollers 343 stop rotating, the pressure of the paper pressing wheel 450 on the cardboard can fix the position of the cardboard. Then the punching cylinder 422 drives the punching die 423 to descend and punch the cardboard on the punching table 410, thereby completing the punching operation of the cardboard. After the punching is completed, the driving component drives the two rollers 343 to rotate, transporting the cardboard forward, so that the cardboard leaves the punching table 410. Preferably, the driving component is a motor.

[0090] 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.

[0091] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
