Technical Field

[0001] This invention relates to the field of eraser wrapping technology, and more specifically, to a fully automatic paper wrapping machine for triangular erasers. Background Technology

[0002] Eraser wrapping paper protects erasers, making them easier to carry and use, while also enhancing the product's aesthetics and appeal. Specifically, the wrapping paper prevents erasers from external contamination and damage, keeping them clean and intact. During carrying and use, the wrapping paper provides a comfortable grip, making it easier for users to handle and operate. Furthermore, an attractive wrapping paper design can make erasers more appealing, enhancing the overall quality and perceived value of the product, thereby increasing users' willingness to purchase and their user experience. Some eraser wrapping papers also feature special patterns or text, making them suitable as gifts or souvenirs, combining practicality and decoration. In general, eraser wrapping paper plays a vital role in protecting the product, facilitating its carrying and use, and enhancing its aesthetics.

[0003] In existing eraser production, the wrapping paper mostly requires manual application of glue and wrapping, which is extremely inefficient. The few that use a combination of semi-automatic and manual wrapping are also inefficient and prone to errors, resulting in poor wrapping quality, especially in the wrapping of triangular erasers. Therefore, in order to solve the above problems, the existence of a fully automatic wrapping machine for triangular erasers is very necessary. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a fully automatic paper wrapping machine for triangular erasers, which can solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, an automatic paper wrapping machine for triangular erasers includes a base. A vibratory feeder is fixedly connected to one side of the base. A conveyor track is fixedly arranged on the side of the vibratory feeder near the base. A first conveyor belt is fixedly arranged on the side of the base near the vibratory feeder. One side of the conveyor track is fixedly connected to the top of the first conveyor belt. A fixed frame is fixedly arranged on the top of the base on one side of the first conveyor belt. A paper wrapping device is fixedly arranged on the fixed frame on one side of the fixed frame. A fixed seat is fixedly arranged on the top of the base on one side of the fixed frame. A paper feeding mechanism is fixedly arranged on one side of the fixed seat. A second conveyor belt is fixedly arranged on one side of the fixed frame next to the paper wrapping device. The paper wrapping device includes a fixed disk fixedly arranged on one side of the fixed frame. A rotating disk is rotatably arranged inside the fixed disk. Eight locking blocks are evenly arranged on the outer side of the rotating disk. The outer side of the rotating disk is connected to the second conveyor belt. The top side of the conveyor belt is tangent to the bottom. A feeding structure is fixedly installed on one side of the fixed plate at the tangent point between the rotating plate and the second conveyor belt. A feeding mechanism is fixedly installed on the top of the base below the rotating plate. The feeding mechanism includes a baffle fixedly installed on the top of the base. The baffle is located directly below the rotating plate. A product is slidably arranged on the inner side of the baffle. A glue applicator is rotatably installed on one side of the baffle on the top of the base. The paper feeding mechanism includes a paper feeding platform fixedly installed on the top of the base. One side of the paper feeding platform is located outside the baffle. Packaging paper is slidably placed on the top of the paper feeding platform. The packaging paper is slidably placed on the middle side of the baffle and directly above the product.

[0006] Furthermore, the paper wrapping device also includes a pressing plate fixedly disposed on the outside of the fixed plate. The pressing plate is semi-circular and fixedly disposed on the side of the fixed plate away from the second conveyor belt. The inner side of the pressing plate is in contact with the clamping block. A fourth push rod is fixedly disposed on the top of the base on the side of the baffle close to the second conveyor belt. The output end of the fourth push rod moves horizontally on the top of the baffle. The feeding mechanism also includes a first push rod fixedly disposed inside the base. The output end of the first push rod is located directly below the product and is in close contact with the bottom of the product.

[0007] Furthermore, the paper feeding mechanism also includes a rotating rod rotatably mounted on one side of the fixed base, a suction cup rotatably mounted on one side of the rotating rod, a placement box fixedly mounted on the fixed base above the rotating rod, and a second push rod fixedly mounted on the top of the base below the placement box, the output end of the second push rod moving horizontally inside the paper feeding platform.

[0008] Furthermore, the feeding mechanism includes a fifth push rod fixedly disposed inside the fixed plate, and each of the eight clamping blocks has a feeding groove on its inner side. Each of the eight feeding grooves cooperates with the output end of the fifth push rod, and the output end of the fifth push rod moves horizontally to the top of the second conveyor belt near the rotating plate.

[0009] Furthermore, the glue applicator is located on the inner side of the bottom of the packaging paper, and multiple glue outlet holes are provided on the outer side of the glue applicator.

[0010] Furthermore, a limiting plate is fixedly installed on the top of the base on one side of the first push rod, and one side of the limiting plate is fixedly connected to the baffle. A limiting rod is telescopically installed on the top of the base above the limiting plate.

[0011] Furthermore, a square groove is provided on one side of the extrusion plate, and a third push rod is fixedly provided on the fixing seat near the square groove, with the output end of the third push rod slidingly engaged with the inside of the square groove.

[0012] Furthermore, a universal joint is rotatably connected to one side of the fixed base, and a control box is rotatably connected to one side of the universal joint.

[0013] The beneficial effects of the fully automatic paper wrapping machine for triangular erasers of the present invention are as follows: By setting up a paper wrapping device and a paper feeding mechanism, during use, the product moves to the bottom of the paper wrapping device via a vibrating plate and the first conveyor belt. The feeding mechanism moves the packaging paper to the top of the product. Under the push of the feeding mechanism, the product and packaging paper cooperate with the card block and complete the paper wrapping operation inside the paper wrapping device. This effectively realizes the replacement of manual operation with mechanical operation and greatly increases the efficiency of paper wrapping with the triangular eraser. By setting up the first pusher and the extrusion plate, the paper feeding mechanism transports the packaging paper between the card block and the baffle. During this process, one side of the packaging paper contacts the glue applicator to complete the glue application. The first pusher pushes the product and packaging paper into the inside of the card block inside the wrapping device. Then, the fourth pusher pushes and extrudes the packaging paper to wrap the bottom of the product. Immediately afterwards, the rotating disk drives the card block to rotate, so that the other side of the packaging paper is squeezed by the extrusion plate to complete the wrapping operation. The wrapping efficiency is higher, and multiple products can be wrapped at high speed through multiple card blocks, making it more practical. By incorporating a rotating rod and a second push rod, the rotating rod picks up the packaging paper from the suction cup and moves it above the paper feeding platform. The second push rod then conveys the packaging paper above the product, improving conveying stability while maintaining high-speed paper transport. The fifth push rod, in conjunction with the feeding chute, ensures stable feeding. A glue applicator, rotating while discharging glue through multiple small holes, effectively improves glue application efficiency. Limiting rods and plates limit the position of the product at the rear, enhancing operational stability. A square groove and a third push rod, working together, compress the packaging paper, further improving the adhesion stability of the glued area. A control box provides convenient operation.

One side of the conveyor track 20 is fixedly connected to the top of the first conveyor belt 12. A fixed frame 10 is fixedly installed on the top of the base 1 on one side of the first conveyor belt 12. A paper wrapping device 3 is fixedly installed on the fixed frame 10 near the first conveyor belt 12. A fixed seat 11 is fixedly installed on the top of the base 1 on one side of the fixed frame 10. A paper feeding mechanism 4 is fixedly installed on one side of the fixed seat 11. A second conveyor belt 7 is fixedly installed next to the paper wrapping device 3 on one side of the fixed frame 10. The paper wrapping device 3 includes a fixed disk 30 fixedly installed on one side of the fixed frame 10. A rotating disk 31 is rotatably installed inside the fixed disk 30. Eight locking blocks 32 are evenly arranged on the outer side of the rotating disk 31. The outer side of the rotating disk 31 is tangent to one side of the top of the second conveyor belt 7. A feeding structure is fixedly installed on one side of the fixed disk 30 at the tangent point between the rotating disk 31 and the second conveyor belt 7. A feeding mechanism is fixedly installed on the top of the base 1 below the rotating disk 31. The feeding mechanism includes a fixed... A baffle 18 is fixedly installed on the top of the base 1, directly below the rotating disk 31. The product 5 is slidably arranged on the inner side of the baffle 18. A glue applicator 50 is rotatably arranged on one side of the baffle 18 on the top of the base 1. The paper feeding mechanism 4 includes a paper feeding platform 42 fixedly installed on the top of the base 1. One side of the paper feeding platform 42 is located outside the baffle 18. A packaging paper 51 is slidably placed on the top of the paper feeding platform 42. The packaging paper 51 is slidably placed on the middle side of the baffle 18 and directly above the product 5. By setting up the paper wrapping device 3 and the paper feeding mechanism 4, during use, the product 5 is moved to the bottom of the paper wrapping device 3 by the vibrating disk 2 and the first conveyor belt 12. The unloading mechanism moves the packaging paper 51 above the product 5. Under the push of the loading mechanism, the product 5 and the packaging paper 51 cooperate with the card block 32 and complete the paper wrapping operation inside the paper wrapping device 3. This effectively realizes the replacement of manual operation by machinery and greatly increases the efficiency of paper wrapping of the triangular eraser.

[0019] In this embodiment, the paper wrapping device 3 further includes a pressing plate 33 fixedly disposed on the outside of the fixed disk 30. The pressing plate 33 is semi-circular and fixedly disposed on the side of the fixed disk 30 away from the second conveyor belt 7.

The eight feeding slots 35 are all engaged with the output end of the fifth push rod 70. The output end of the fifth push rod 70 moves horizontally to the top of the side of the second conveyor belt 7 near the rotating plate 31. Feeding is carried out by the cooperation of the fifth push rod 70 and the feeding slots 35, which makes the feeding more stable.

[0022] In this embodiment, the glue applicator 50 is located on the inner side of the bottom of the packaging paper 51, and multiple glue outlet holes are provided on the outer side of the glue applicator 50. By setting the glue applicator 50, the glue is discharged through multiple small holes while the glue applicator 50 rotates, which effectively improves the glue application efficiency.

[0023] In this embodiment, a limiting plate 14 is fixedly installed on the top of the base 1 on one side of the first push rod 15. One side of the limiting plate 14 is fixedly connected to the baffle 18. A limiting rod 13 is telescopically installed on the top of the base 1 above the limiting plate 14.
