Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, and in particular to a paperboard edge-wrapping and feeding mechanism. Background Technology

[0002] A cardboard box is a three-dimensional shape, which is composed of a number of facets that are moved, stacked, folded and surrounded. In the three-dimensional composition, the facets play the role of dividing space. In production, a layer of decorative paper needs to be pasted on the outside of the box.

[0003] Traditional techniques lack precise control over the paper bending process, leading to quality problems after edge binding. Specifically, this manifests as: the inability to ensure consistent bending angles along the cardboard edge, resulting in excessively large or small bending angles in some areas, directly causing loose edge binding and poor adhesion between the paper and cardboard surface. Furthermore, the lack of targeted anti-shifting measures during bending allows the paper to easily shift position, forming bulges at the edge binding and compromising the overall smoothness of the binding. Utility Model Content

[0004] The purpose of this utility model is to provide a cardboard edge-wrapping and feeding mechanism to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A paperboard edge-wrapping feeding mechanism includes a side edge-wrapping module and a transfer module. The side edge-wrapping module includes a pressing assembly and an edge-wrapping assembly. The pressing assembly includes longitudinally moving upper and lower pressure plates, which are respectively disposed on both sides of the paperboard in the forward direction. The edge-wrapping assembly includes a paperboard support plate aligned longitudinally with the upper and lower pressure plates and a paperboard edge-wrapping plate located on top of the paperboard support plate. The bottom surface of the paperboard edge-wrapping plate is flush with the top surface of the paperboard support plate. The paperboard edge-wrapping plate can move laterally to bend the paper sheet inward to surround the edge of the paperboard.

[0007] The transfer module includes a transfer plate that moves along the direction of paperboard movement, and the transfer plate is equipped with an adsorption tray for adsorbing the paperboard.

[0008] Furthermore: a support drive plate is provided on the outside of the cardboard support plate, and the support drive plate is provided with a transverse drive component, the drive end of which is connected to the cardboard edge banding plate.

[0009] Furthermore: Supporting guide rails are provided at the bottom of the supporting drive plate and the cardboard edge banding plate. Edge banding limiting seats and edge banding follower seats are slidably installed on the supporting guide rails. The top of the edge banding limiting seat is connected to the cardboard edge banding plate, and the edge banding follower seat is connected to the supporting drive plate.

[0010] Furthermore, the edging assembly also includes a guide adjustment rod arranged along the length of the support rail, the guide adjustment rod being fitted with a bottom adjustment seat, and the bottom adjustment seat being connected to the support drive plate.

[0011] Furthermore, the pressing assembly also includes a pressing lifting drive unit installed on the support drive plate. The driving end of the pressing lifting drive unit is equipped with a lifting guide plate that extends laterally to the upper and lower pressure plates. The lifting guide plate is connected to the upper and lower pressure plates.

[0012] Furthermore, the transfer module also includes side drive plates arranged along the forward direction of the cardboard. The side drive plates are respectively set on both sides of the forward direction of the cardboard, and a transfer gantry is set between the two side drive plates. The transfer plate is set on the transfer gantry.

[0013] Furthermore: the transfer gantry is slidably mounted with a transfer sliding seat, the transfer plate is mounted on the transfer sliding seat, and the transfer gantry is provided with an adjustment structure for adjusting the lateral position of the transfer plate.

[0014] Furthermore: the side drive plate is provided with a conveying mechanism along its length, and the drive end of the conveying mechanism is equipped with a transmission seat, which can move along the length of the side drive plate and is connected to the transfer gantry.

[0016] Furthermore, the transfer module also includes a discharge pusher plate that pushes the cardboard from the side-sealing module into the discharge conveyor belt, and the height of the discharge pusher plate is adjustable.

[0017] The beneficial effects of this utility model are as follows: Two opposing sides of the cardboard with edge banding are transferred and adsorbed into the cardboard support plate through the transfer module, supporting the cardboard. Then, the upper and lower pressure plates of the pressing assembly press down to position the cardboard on the top of the cardboard support plate.

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] like Figure 1-4As shown, a cardboard edge-wrapping feeding mechanism includes a side edge-wrapping module 1 and a transfer module 4. The side edge-wrapping module 1 includes a pressing assembly 11 and an edge-wrapping assembly 2. The pressing assembly 11 includes upper and lower pressure plates 12 that move longitudinally. The upper and lower pressure plates 12 are respectively disposed on both sides of the cardboard in the forward direction. The edge-wrapping assembly 2 includes a cardboard support plate 21 that is longitudinally aligned with the upper and lower pressure plates 12 and a cardboard edge-wrapping plate 22 located on top of the cardboard support plate 21. The bottom surface of the cardboard edge-wrapping plate 22 plus the total thickness of the product forming is flush with the top of the cardboard support plate 21. The cardboard edge-wrapping plate 22 can move laterally to bend the paper sheet inward to surround the edge of the cardboard. The transfer module 4 includes a transfer plate 45 that moves along the forward direction of the cardboard. The transfer plate 45 is equipped with an adsorption tray 47 for adsorbing the cardboard.

[0039] Two opposing edges of the cardboard are transferred to the cardboard support plate 21 via the transfer module 4. The cardboard is then supported, and the upper and lower pressure plates 12 of the pressing assembly 11 press down to position the cardboard on top of the cardboard support plate 21. Under the limiting action of the cardboard edge-wrapping plate 22, a 90-degree bend is formed between the edges of the paper and the cardboard. The cardboard edge-wrapping plate 22 then moves laterally closer to the cardboard, bending the outward-extending paper along the edge of the cardboard inward. The paper can surround the edge of the cardboard and adhere to the surface of the cardboard to prevent poor quality, thus achieving edge wrapping. The pressing of the upper and lower pressure plates 12 prevents the cardboard from moving, ensures that the paper bends along the edge of the cardboard, and ensures the quality of the wrapping. This results in consistent bending angles and tight adhesion of the paper, effectively solving the quality defects such as loose edges and bulging that are common in traditional technologies.

[0040] Specifically, the cardboard support plate 21 rises and falls to the height required for product forming according to the product thickness, at which point a 90-degree bend is formed between the edges of the paper sheet and the cardboard. A support drive plate 23 is provided on the outside of the cardboard support plate 21, and a transverse drive member 24 is provided on the support drive plate 23. The drive end of the transverse drive member 24 is connected to the cardboard edge-wrapping plate 22. Under the drive of the transverse drive member 24, the cardboard edge-wrapping plate 22 can extend, aligning the cardboard and paper sheet of the cardboard support plate 21. The cardboard edge-wrapping plate 22 extends outward, and the paper sheet is pushed inward and bent, achieving initial edge wrapping of the paper sheet against the edge of the cardboard, increasing the fit of the edge wrapping, and ensuring the quality of the edge wrapping.

[0041] Preferably, the lateral drive component 24 can be a telescopic cylinder, a cam mechanism, or any power drive mechanism.

[0042] Furthermore, a support guide rail 36 is provided at the bottom of the support drive plate 23 and the cardboard edge-wrapping plate 22. An edge-wrapping limiting seat 37 and an edge-wrapping follower seat 38 are slidably mounted on the support guide rail 36. The edge-wrapping limiting seat 37 cooperates with the cardboard edge-wrapping plate 22, and the edge-wrapping follower seat 38 is combined and connected with the support drive plate 23. In this embodiment, when the cardboard edge-wrapping plate 22 drives the paper sheet to bend and wrap the edge of the cardboard, the edge-wrapping limiting seat 37 and the edge-wrapping follower seat 38, in cooperation with the support guide rail 36, slide precisely in one or two directions according to changes in product size and various product shapes, achieving precise edge-wrapping and forming of the fed product, thus improving the quality of the edge wrapping. In addition, the edge-wrapping limiting seat 37 and the edge-wrapping follower seat 38 can move inward and outward according to product size requirements as they move on the support guide rail 36, realizing the adjustment of the product's length and position, thus meeting the edge-wrapping forming needs of cardboard of different sizes.

[0043] There are two cardboard support plates 21, which support the bottom surfaces of the left and right ends of the cardboard respectively, increasing the stability of the cardboard support. Multiple intermediate support plates 28 are arranged between the two cardboard support plates 21. The intermediate support plates 28 and the cardboard support plates 21 further increase the number of support points, preventing the cardboard from becoming uneven due to gravity or other factors, and ensuring that the dimensions of the edge of the product remain unchanged during edge binding to ensure the stability of production quality.

[0044] Furthermore, a bottom mounting plate 3 is provided at the bottom of the cardboard support plate 21, and a bottom drive frame 31 is provided below the bottom mounting plate 3. The bottom drive frame 31 is provided with a bottom lifting screw 32. The drive end of the bottom lifting screw 32 is connected to the bottom mounting plate 3. Under the drive of the servo motor, the bottom mounting plate 3 moves up and down according to the thickness of the product. At the same time, the cardboard support plate 21 and the middle support plate 28 move up and down synchronously, which can raise or lower the cardboard to the height required for edge wrapping, so as to realize the bending and wrapping of the edge. After the action is completed, it is adsorbed by the transfer module to realize the discharge.

[0045] Preferably, the cardboard support plate 21 is equipped with a transversely arranged transverse extension plate 25, which extends toward the support drive plate 23. A support column 26 is installed on the extended part of the support drive plate 23. The support drive plate 23 is formed with a sliding guide hole 27 coaxially aligned with the support column 26. The support column 26 and the sliding guide hole 27 are slidably engaged, so that the support drive plate 23 and the cardboard support plate 21 are combined to achieve the change of the wrapping and forming position according to the product size. The bottom mounting plate 3 is equipped with a pair of parallel and spaced bottom guide rails 33. The bottom guide rails 33 are parallel to the support guide rails 36 and move vertically or up and down during operation. The bottom guide rails 33 are equipped with bottom sliding seats. The cardboard support plate 21 is installed on the bottom sliding seats. The length distance between the two cardboard support plates 21 can be adjusted by the sliding engagement between the bottom sliding seats and the bottom guide rails 33 to achieve the wrapping of cardboard of different lengths.

[0046] Furthermore, the edge-binding assembly 2 also includes a guide adjustment rod 34 arranged along the length of the support guide rail 36. The guide adjustment rod 34 is fitted with a bottom adjustment seat 35, which is connected to the support drive plate 23. Since the support drive plate 23 is connected to the cardboard support plate 21, when the position of the support drive plate 23 is adjusted, both ends of the cardboard support plate 21 move independently to ensure that the cardboard edge-binding plate 22 reaches the forming position required by the product.

[0047] Furthermore, the pressing assembly 11 also includes a pressing lifting drive 13 mounted on the support drive plate 23. The driving end of the pressing lifting drive 13 is equipped with a lifting guide plate 14 extending laterally to the upper and lower pressure plates 12, and the lifting guide plate 14 is connected to the upper and lower pressure plates 12. Under the drive of the pressing lifting drive 13, the cardboard placed on the cardboard support plate 21 is pressed and positioned. During edge binding, the cardboard will not shift or loosen to the left or right. When the cardboard edge binding plate 22 approaches the cardboard, it can move according to a preset travel distance, driving the paper sheet to bend inward along the edge of the cardboard until the paper sheet can surround the edge of the cardboard, thereby achieving edge binding.

[0048] Preferably, the pressing and lifting drive component 13 can be a lifting cylinder.

[0049] The transfer module 4 also includes side drive plates 41 arranged along the paperboard's forward direction. The side drive plates 41 are respectively positioned at the paperboard's inlet and outlet. A transfer gantry 40 is positioned between the two side drive plates 41. A transfer plate 45 is mounted on the transfer gantry 40. A transfer sliding seat 42 is slidably installed on the transfer gantry 40, and the transfer plate 45 is mounted on the transfer sliding seat 42. The transfer gantry 40 is equipped with a buffer structure for adjusting the vertical position of the transfer plate 45. The transfer gantry 40 moves along the length of the side drive plates 41 according to product requirements via the transfer sliding seat 42, allowing the paperboard to be absorbed from the previous process station and transferred to the paperboard support plate 21 of the side edge-wrapping module 1, thus achieving feeding and wrapping.

[0050] Furthermore, the discharge port of the side edge-wrapping module 1 is connected to a feeding module 5. The feeding module 5 includes a discharge conveyor belt 51 for forward conveying of the edged cardboard. Along the discharge conveyor belt 51, there are rolling components for rolling the cardboard. The rolling components include a pair of parallel and spaced guide rollers 52, through which the edged cardboard can pass. The edged cardboard is moved into the discharge conveyor belt 51 of the feeding module 5 for conveying. After passing through the rolling components, the rolling components roll the cardboard forward, which can further press and flatten the edged area, increasing the flatness of the cardboard, before it is discharged.

[0051] Specifically, the transfer module 4 also includes a feeding pusher plate 53 that moves the cardboard from the side-sealing module 1 into the discharge conveyor belt 51. The feeding pusher plate 53 is installed on the transfer sliding seat 42, and the height of the feeding pusher plate 53 is elastically adjustable. The transfer gantry 40 is equipped with a sliding flexible seat 54 and a discharge lifting cylinder 55. The sliding flexible seat 54 is elastically connected to the transfer plate 45. The sliding flexible seat 54 is equipped with an adsorption guide rod 46, and the adsorption guide rod 46 is fitted with a transfer buffer spring. When the adsorption plate 47 of the transfer plate 45 needs to adsorb and transfer the cardboard, the transfer plate 45 moves above the cardboard support plate 21 under the movement of the transfer gantry 40. Then the cardboard support plate 21 rises, pushing the cardboard up so that the cardboard is in contact with the adsorption plate 47 of the transfer plate 45. At this time, the transfer plate 45 has a buffering effect under the elastic action of the adsorption guide rod 46 and the transfer buffer spring.

[0052] The drive end of the discharge lifting cylinder 55 is combined with the discharge push plate 53. The discharge push plate 53 is located in front of the transfer gantry 40, and the transfer plate 45 is located behind the discharge push plate 53.

[0053] While the transfer gantry 40 feeds cardboard from the previous process onto the cardboard support plate 21, the unloading pusher 53 descends one step in advance. The unloading pusher 53 blocks the rear end of the cardboard, moving the cardboard from the cardboard support plate 21 into the discharge conveyor belt 51 of the unloading module 5, thus reserving space for new cardboard to enter the cardboard support plate 21. This eliminates the need to combine feeding and unloading in the same module, increasing production efficiency, achieving one-stop forming, and saving space.

[0054] Furthermore, a conveying mechanism 43 is provided along the length of the side drive plate 41. A transmission seat 44 is mounted on the drive end of the conveying mechanism 43. The transmission seat 44 can move along the length of the side drive plate 41 and is connected to the transfer gantry 40. When the conveying mechanism 43 moves, its drive end can move along the length of the side drive plate 41 to drive the transmission seat 44 to move synchronously, so that the transfer gantry 40 can move along the length of the side drive plate 41 via the transfer sliding seat 42.

[0055] Preferably, the conveying mechanism 43 is a belt drive component, which moves under the drive of a motor. One of its long sides is connected to the transmission seat 44 along the path. When the belt drive component moves, it drives the transfer gantry 40 to move along the length direction of the side drive plate 41 through the transmission seat 44, thereby realizing the loading and unloading of cardboard.

[0056] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
