Description

Technical Field

[0001] This utility model belongs to the field of bedding packaging technology, specifically a paper card conveying and folding mechanism. Background Technology

[0002] In modern bedding packaging processes, the labels or reinforcements used to wrap the waist of the rolled-up bedding are often made of thin materials such as paper, plastic, or rubber. While these materials offer advantages such as low cost, ease of processing, and environmental friendliness, they are generally soft and lack rigidity. In automated packaging processes, these materials need to be automatically conveyed and inserted into the rolled-up bedding. However, due to their soft texture, they are difficult to maintain a stable shape during the pushing and positioning stages, resulting in a complex operation and high precision requirements for the equipment.

[0003] Existing technologies typically employ conventional pushing mechanisms in conjunction with fixed guide channels to transport and insert thin sheet materials. However, this type of structure does not adequately consider the mechanical challenges posed by the flexibility of materials. In actual operation, when the material is too thin, due to a lack of sufficient support and pretreatment, the overall structure is easily obstructed and deformed during insertion, even resulting in wrinkles, tears, and other damage. Especially in high-speed continuous operation environments, flexible materials are difficult to maintain a straight-line propulsion state, often resulting in deviation, jamming, or breakage midway, severely impacting packaging success rate and production efficiency.

[0004] Therefore, there is an urgent need to propose a paper card conveying and folding mechanism to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a paper card conveying and folding mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper card conveying and folding mechanism, comprising a carrying mechanism, a paper card conveying mechanism, and a paper card shaping mechanism; the paper card conveying mechanism includes a third mounting frame, a second rotating shaft rotatably mounted on the carrying mechanism, and the third mounting frame fixedly connected to the second rotating shaft; one end of the inner side of the third mounting frame is provided with a placement plate, and the other end is detachably mounted with two paper card folding limit frames, the distance between the two paper card folding limit frames on opposite sides is adjustable; paper ejection wheels are rotatably mounted on opposite sides of the two paper card folding limit frames, and a paper feeding conveyor belt is provided below the paper ejection wheels. The paper ejector wheel and the paper feeding conveyor belt are both connected to the third drive mechanism; the paper card shaping mechanism includes a second mounting frame, a first rotating shaft is rotatably mounted on the bearing mechanism, and the second mounting frame is fixedly connected to the first rotating shaft; the inner side of the second mounting frame is provided with a first paper card conveying assembly and a second paper card conveying assembly arranged in parallel, and both the first paper card conveying assembly and the second paper card conveying assembly are connected to the second drive assembly; the front and rear ends of the second paper card conveying assembly are provided with folding frames; wherein, the paper card conveying mechanism is located to the right of the paper card shaping mechanism, and the two are arranged adjacent to each other in the horizontal direction.

[0007] Preferably, the supporting mechanism includes a base frame and an adjusting cylinder, wherein the adjusting cylinder is mounted on the base frame.

[0008] Preferably, it also includes a bedding feeding mechanism, which includes a fourth mounting frame and a bedding conveying assembly. The fourth mounting frame is mounted above the base frame, and the bedding conveying assembly is located inside the fourth mounting frame.

[0009] Preferably, the second mounting bracket is provided with a connecting rod, one end of which is fixedly connected to the second mounting bracket, and the other end is rotatably connected to the telescopic end of the adjusting cylinder.

[0010] Preferably, the device further includes an adhesive applicator, which includes a first mounting frame fixed to a second mounting frame. Clamping frames are provided on both sides of the upper end face of the first mounting frame, and a loading frame is fixed on the upper end face. An adhesive applicator assembly is slidably mounted on the loading frame. The adhesive applicator assembly is connected to the first driving assembly. The adhesive applicator is located to the left of the cardboard shaping mechanism.

[0011] Preferably, it further includes a positioning pressure roller, which is rotatably mounted on the side above the second paper conveying assembly near the glue coating mechanism.

[0012] Preferably, the paper cards stacked on the placement plate have one bottom end located on the paper pick-up conveyor belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention applies pressure to both sides of the paper card to form pre-creases by setting two paper card folding limit frames in the paper card conveying mechanism. Combined with the reverse transmission of the paper ejection wheel and the paper picking conveyor belt, it achieves stable single-sheet paper picking, thus achieving the effect of preliminary shaping of soft paper cards during conveying and preventing deviation and jamming. The paper card shaping mechanism uses a first paper card conveying component and a second paper card conveying component to clamp and convey the paper card synchronously. The folding frame then performs a secondary bending of the formed creases, enhancing the edge strength of the paper card, eliminating burrs, and maintaining the overall flatness of the paper card. By arranging the paper card conveying mechanism and the paper card shaping mechanism adjacent to each other in the horizontal direction, and both being rotatably mounted on the carrying mechanism via a first and second rotating shaft, the paper card maintains a continuous and stable posture during pushing, avoiding wrinkles, tears, or insertion failures caused by the softness of the material. The synergistic effect of the overall structure effectively solves the technical problem in existing technologies where thin paper cards are difficult to convey stably and insert accurately in automated packaging due to insufficient rigidity.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 7 As shown, this utility model provides a paper card conveying and folding mechanism, including a carrying mechanism 1, a gluing mechanism 2, a paper card shaping mechanism 3, a paper card conveying mechanism 4, and a bedding feeding mechanism 5.

[0018] The supporting mechanism 1 includes a base frame 11 and an adjusting cylinder 12, which is mounted on the base frame 11. The base frame 11 is a rectangular frame structure used to support the main components of the entire device; the piston rod end of the adjusting cylinder 12 is rotatably connected to the connecting rod 311 through a connector, so that the paper card shaping mechanism 3 can swing around the first rotating shaft 32.

[0019] The bedding feeding mechanism 5 is installed above the base frame 11 and is used to transport bedding. The bedding feeding mechanism 5 includes a fourth mounting frame 51 and a bedding conveying assembly 52. ​​The fourth mounting frame 51 has a long, narrow frame structure with support feet at both ends, and is stably mounted on the base frame 11. The bedding conveying assembly 52 is located inside the fourth mounting frame 51 and consists of a conveyor belt, used to smoothly feed the laid-out bedding into the winding device. The bedding conveying assembly 52 adopts a retractable conveyor belt structure, where the conveyor belt's reel is fixedly connected to the piston rod of a cylinder and slides reciprocally along a parallel guide rail, thereby realizing the telescopic movement of the conveyor belt's front end. When feeding is required, the bedding conveying assembly 52 extends forward, feeding the bedding into the winding device to ensure precise alignment. This retractable conveyor belt structure and its driving method are conventional technologies in the field.

[0020] The paper card conveying mechanism 4 is rotatably mounted on the carrying mechanism 1 via a second rotating shaft 42, specifically, the second rotating shaft 42 is rotatably mounted on the base frame 11, and the third mounting frame 41 is fixedly connected to the second rotating shaft 42. A placement plate 43 is provided on one end of the inner side of the third mounting frame 41 for stacking paper cards to be used, and the bottom end of the paper cards stacked on the placement plate 43 is located on the paper feeding conveyor belt 46. An infrared sensing component is provided on the third mounting frame 41. The upper infrared sensor monitors the stacking height of the paper cards at the placement plate 43. When the remaining paper card amount is lower than a set threshold, the system automatically issues a feeding reminder. The lower infrared sensor is located at the entrance of the paper feeding conveyor belt 46 or the starting end of the first paper card conveying component 33 to detect whether a paper card has entered the conveying channel. If no paper card is detected, it is determined to be a paper feeding abnormality and triggers a shutdown protection. The above infrared sensing detection scheme is a standard configuration in automated feeding systems. The distance between the two paper card folding limit frames 47 on opposite sides is adjustable to accommodate different specifications of paper cards. Two paper folding edge limiting frames 47 are rotatably mounted on opposite sides with paper ejector rollers 45, and a paper feeding conveyor belt 46 is provided below the paper ejector rollers 45. Both the paper ejector rollers 45 and the paper feeding conveyor belt 46 are connected to the third drive mechanism 44 and rotate in opposite directions, realizing the function of picking up paper layer by layer from the bottom and pushing it forward. During the movement of the paper card, the paper folding edge limiting frames 47 apply pressure to both sides of it, causing it to form a preset crease and bend slightly upward.

[0021] The paper card shaping mechanism 3 is rotatably mounted on the bearing mechanism 1 via a first rotating shaft 32. Specifically, the first rotating shaft 32 is rotatably mounted on the base frame 11, and the second mounting frame 31 is fixedly connected to the first rotating shaft 32. The paper card shaping mechanism 3 includes a second mounting frame 31, a first paper card conveying assembly 33, a second paper card conveying assembly 34, a positioning pressure roller 35, a folding frame 36, and a second drive assembly 37. The second mounting frame 31 is provided with a connecting rod 311. One end of the connecting rod 311 is fixedly connected to the second mounting frame 31, and the other end is rotatably connected to the telescopic end of the adjusting cylinder 12. The first paperboard conveying assembly 33 and the second paperboard conveying assembly 34 are arranged parallel to each other inside the second mounting frame 31 and are both connected to the second drive assembly 37 for transmission. Together, they clamp the paperboard and convey it to the gluing mechanism 2. The folding frame 36 is located at the front and rear ends of the second paperboard conveying assembly 34 and is used to perform secondary bending on the creases formed on both sides of the paperboard. The positioning pressure roller 35 is rotatably installed on the side of the second paperboard conveying assembly 34 near the gluing mechanism 2 to ensure the flatness of the paperboard during the conveying process.

[0022] The gluing mechanism 2 is fixedly mounted on the second mounting frame 31 and is used to apply glue to the conveyed paper cards. The gluing mechanism 2 includes a first mounting frame 21, a clamping frame 22, a loading frame 23, a gluing assembly 24, and a first drive assembly 25. The first mounting frame 21 is fixed on the second mounting frame 31; two clamping frames 22 are respectively located on both sides of the upper end face of the first mounting frame 21 to limit the left and right sides of the paper cards; the loading frame 23 is fixed on the upper end face of the first mounting frame 21, and the gluing assembly 24 is slidably mounted on the loading frame 23 and is connected to the first drive assembly 25 for transmission; the gluing mechanism 2 is located to the left of the paper card shaping mechanism 3.

[0023] Working principle and usage process of this utility model: The worker first lays out the bedding and folds it, then starts the bedding conveyor assembly 52. ​​The bedding conveyor assembly 52 extends forward, feeding the bedding into the winding device to ensure precise alignment. Simultaneously, paper cards pre-stacked on the placement plate 43 are taken out layer by layer from the bottom by the paper-taking conveyor belt 46, and pushed into the paper card shaping mechanism 3 with the assistance of the paper-retracting roller 45. During this process, the paper cards are subjected to pressure from the paper card folding limit frame 47, forming initial creases on both sides and curling upwards. Subsequently, the paper cards are clamped and conveyed to the folding frame 36 by the first paper card conveyor assembly 33 and the second paper card conveyor assembly 34. The folding frame 36 performs a secondary bending of the creases on both sides of the paper cards, enhancing structural strength and eliminating burrs. The positioning pressure roller 35, in conjunction with the second paper card conveyor assembly 34, ensures the stability of the paper card's posture. When the paper card is conveyed to the predetermined position, the adjusting cylinder 12 is activated, driving the second mounting frame 31 to swing downwards around the first rotating shaft 32 via the connecting rod 311, causing the front end of the paper card to insert into the winding bedding. At this point, the gluing assembly 24 moves horizontally along the loading frame 23 under the drive of the first drive assembly 25, applying glue evenly to the exposed surface of the paper card. After gluing is completed, the paper card continues to roll up with the bedding, finally wrapping around the waist of the bedding to complete the packaging.
