Description

Technical Field

[0001] This utility model relates to the field of cardboard manufacturing equipment technology, and in particular to a continuous paper feeding adjustment device for cardboard. Background Technology

[0002] Cardboard boxes are the most widely used packaging products, and packaging cardboard boxes are an indispensable part of modern logistics. Commonly used packaging cardboard boxes mainly use corrugated cardboard boxes and single-layer cardboard boxes. Both corrugated cardboard boxes and single-layer cardboard boxes are formed by cutting and creasing cardboard, then folding and gluing them together to form the box shape.

[0003] In the existing production process, cardboard boxes need to be cut to a certain size by a cutting mechanism and creasing by a creasing mechanism so that the cardboard can be folded along the creasing to form a carton. Since most of the existing cutting and creasing mechanisms rely on manual feeding to place the cardboard, the manual feeding is inefficient and cannot guarantee the accuracy of the paper feeding position, which affects the creasing and cutting quality of the cardboard. Therefore, most existing cutting and creasing equipment is equipped with a conveyor belt to achieve continuous paper feeding, which can effectively improve work efficiency. However, when using a conveyor belt to transport cardboard of different thicknesses to the creasing and cutting station, it cannot be guaranteed that the cardboard will enter the creasing and cutting station straight. It can also cause cardboard stacking and cardboard end warping and jamming when transporting cardboard of different thicknesses to the creasing and cutting station.

[0004] Referring to patent publication number "CN215047194U", patent title "A feeding device for a corrugated cardboard creasing machine", this technical solution discloses "a feeding device for a corrugated cardboard creasing machine, including a base frame and a support mechanism. The support mechanism is slidably connected to the left side of the top upper surface of the base frame. The support mechanism specifically consists of a limiting shaft, a drive roller, and a support rod. The support rod is slidably connected to the middle position of the left side of the top upper surface of the base frame. A limiting shaft is inserted into the middle position of the top of the support rod. The end of the limiting shaft away from the support rod is movably connected to the drive roller." The device utilizes a main... The moving roller, guide plate, and driven roller convey the corrugated cardboard, and the stable connection ensures stable conveying of the corrugated cardboard. The slide groove is opened on the upper surface of the base frame and connected to the slider and the driving roller. Although this technical solution can adjust the relative position of the driving roller and the base frame to accommodate corrugated cardboard of different lengths, it cannot effectively adjust the paper thickness and is not suitable for continuous feeding of corrugated cardboard with different thicknesses. During the continuous stacking and feeding of corrugated cardboard, it is easy to cause the cardboard to jam, affecting the subsequent creasing and cutting processing of the cardboard.

[0005] Therefore, how to achieve continuous and straight feeding of cardboard with different thicknesses is the main technical problem that technicians need to solve. Utility Model Content

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The technical solutions of the embodiments of this utility model are described in detail.

[0033] In Example 1, to achieve continuous feeding of cardboard and maintain the straight feeding of individual sheets to the subsequent workstation, a drive mechanism 3 is provided at the bottom of the feeding platen 1. The drive mechanism 3 includes a rotating motor 31 and a transmission shaft 32. The power output end of the drive mechanism 3 is connected to one end of the transmission shaft 32. The transmission shaft 32 is rotatably mounted at the bottom of the feeding platen 1, and several feeding rollers 33 are sleeved on the outside of the transmission shaft 32. The tops of the feeding rollers 33 extend to the outside of the feeding platen 1. Therefore, the rotating motor 31 can drive the transmission shaft 32 to rotate. The drive shaft 32 rotates, driving several feeding rollers 33 to rotate. When the cardboard is on the feeding plate 1, the feeding rollers 33 can move the cardboard to feed. A strip-shaped protrusion 11 is provided on the top of the feeding plate 1, and the support plate 2 is located directly above the strip-shaped protrusion 11. The pressing mechanism 21 and the guide plate 22 are slidably arranged outside the support plate 2. The pressing mechanism 21 can flatten the cardboard, so that the cardboard is fed straight during the feeding process. The guide plate 22 limits the end of the cardboard, ensuring that multiple cardboards are fed one sheet at a time, and preventing the cardboard from being stacked during feeding.

[0034] It should be noted that several pressing mechanisms 21 and guide plates 22 can be provided. During the paperboard feeding process, several pressing mechanisms 21 can be used to flatten the paperboard, ensuring that the paperboard enters the paper feed opening straight. The several pressing mechanisms 21 and several guide plates 22 are staggered one by one, which can ensure that the paperboard is subjected to uniform force and prevent the paperboard from bending and deforming.

[0035] It should be noted that the bottom of the supporting horizontal plate 2 and the top of the strip protrusion 11 form a paper feeding opening for the paperboard to enter. The bottom of the lifting guide plate 23 corresponds to the paper feeding opening. When the paperboard moves towards the paper feeding opening through the feeding plate 1, the lifting guide plate 23 can limit the end of the paperboard, thus achieving the effect of keeping the single paperboard feeding sequentially when the paperboard is continuously fed.

[0036] It should also be noted that by providing several strip openings 12 on the surface of the feeding plate 1, and distributing these strip openings 12 evenly along the length of the feeding plate 1, so that each strip opening 12 corresponds to a feeding roller 33, the feeding roller 33 can extend out of the feeding plate 1 through the strip openings 12. This allows the feeding roller 33 to contact the top of the cardboard when it is on the feeding plate 1, thereby moving the cardboard toward the paper inlet opening.

[0037] It should be further explained that the pressing mechanism 21 includes a pushing cylinder 211 and a paper pressing plate 212. The paper pressing plate 212 is set on the power output end of the pushing cylinder 211, so that one side of the paper pressing plate 212 faces the feeding plate 1. The pushing cylinder 211 can drive the paper pressing plate 212 to press down towards the feeding plate 1. When the paperboard is driven by the feeding plate 1 to approach the pressing mechanism 21, the paper pressing plate 212 can flatten the end of the paperboard, ensuring that the end of the paperboard can enter the paper feed opening.

[0038] It should also be noted that by providing a guide rail 24 on the outside of the support plate 2, and extending the guide rail 24 along the length of the support plate 2, the pressing mechanism 21 and the guide pressure plate 22 are slidably engaged with the outside of the guide rail 24. Thus, the positions of the pressing mechanism 21 and the guide pressure plate 22 can be adjusted by sliding. In actual production, the positions of the pressing structure and the guide pressure plate 22 can be adjusted according to the width of the cardboard.

[0039] In Example 2, to achieve continuous feeding of cardboard with different thicknesses, the position of the lifting guide plate 23 needs to be adjusted during continuous feeding to accommodate cardboard with different thicknesses and improve its applicability. In this example, a lifting guide plate 23 is movably installed outside the guide pressure plate 22, and an adjusting member 231 is installed on the top of the lifting guide plate 23. The top of the lifting guide plate 23 is connected to the top of the guide pressure plate 22 through the adjusting member 231. The lifting height of the lifting guide plate 23 can be adjusted through the adjusting member 231 to control the distance between the bottom of the lifting guide plate 23 and the top of the feeding plate 1, thereby limiting the feeding of cardboard with different thicknesses and ensuring that cardboard with different thicknesses enters the subsequent workstations one sheet at a time.

[0040] In this embodiment, when the lifting guide plate 23 limits the paperboard, the end of the paperboard will directly collide with the bottom of the lifting guide plate 23, causing the end of the paperboard to curl outwards. Therefore, it is necessary to supplement that: the bottom of the supporting horizontal plate 2 and the top of the strip-shaped protrusion 11 can form a paper feeding opening for the paperboard to enter, so that the bottom of the lifting guide plate 23 corresponds to the paper feeding opening. Then, when the end of the paperboard enters the paper feeding opening, the lifting guide plate 23 can limit the end of the paperboard. The side of the lifting guide plate 23 near the feeding plate 1 can be tilted, and both sides of the outer side of the strip-shaped protrusion 11 can be tilted. With an inclined structure, during the paperboard feeding process, the pressing mechanism 21 presses down to place the end of the paperboard at the bottom of the lifting guide plate 23, so that the end of the paperboard is fed through the gap between the lifting guide plate 23 and the strip protrusion 11. The lifting guide plate 23 can limit the paperboard and ensure that only one sheet of paperboard is fed. During this process, the end of the paperboard will directly collide with the bottom of the lifting guide plate 23. Since the side of the lifting guide plate 23 near the feeding plate 1 is inclined, it can prevent the end of the paperboard from directly colliding with the bottom of the lifting guide plate 23 and causing it to warp outward, thus solving the problem of feeding jam caused by the warping of the end of the paperboard.

[0041] Example 3, in conjunction with Examples 1 and 2, aims to limit the position of the cardboard during continuous feeding to prevent positional deviation. In this example, several sets of baffle plates 4 are slidably arranged on the outside of the supporting horizontal plate 2. Each set of baffle plates 4 includes two opposing baffle side plates, with the opposing side of the two baffle side plates forming a clamping surface for holding the cardboard. The stacked cardboard can be clamped by the baffle plates 4, ensuring that cardboard of different thicknesses remains flush on both sides when stacked, thus preventing positional deviation during cardboard feeding.

[0042] In addition to this embodiment, it should be added that both ends of the baffle side plate can be chamfered. When the baffle side plate limits the outer sides of the cardboard to ensure that the cardboard does not deviate during feeding, the end of the cardboard will collide with the end of the baffle side plate because the cardboard is in a moving state during feeding. By chamfering both ends of the baffle side plate, the bending deformation and jamming caused by the direct collision between the end of the cardboard and the end of the baffle side plate can be effectively prevented.

[0043] The present invention has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of each embodiment have different focuses; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments. Those skilled in the art should also understand that the actions and modules involved in the specification are not necessarily essential to the present invention. Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the structure in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.

[0044] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
