Description

Technical Field

[0001] This utility model relates to the field of parcel mechanism technology, specifically a paper packaging parcel mechanism. Background Technology

[0002] Currently, wrapping machines are commonly used for packaging books. A wrapping machine mainly consists of a conveyor belt and chains on either side. Paper-pushing rollers are installed between the chains. One end of the kraft paper is placed above the feed end of the conveyor belt. After the book enters the conveyor belt, it presses down on one end of the kraft paper and moves forward with the belt. When the book reaches the discharge end of the conveyor belt, the chains drive the paper-pushing rollers, which cover the book with the kraft paper. When the book leaves the conveyor belt, both ends of the kraft paper are pressed under the book, thus completing the book wrapping process.

[0003] Chinese Patent Publication No. CN221367720U discloses a cargo packaging mechanism capable of tightening paper, belonging to the technical field of cargo packaging equipment. This mechanism includes a conveyor belt and a paper-feeding roller that can move around the conveyor belt. A paper-pressing component that can move back and forth is provided on the front side of the conveyor belt for pressing kraft paper against the front side of the conveyor belt. By providing a paper-pressing brush on the front side of the conveyor belt to tighten the kraft paper, as the book is about to leave the output end of the conveyor belt, the paper-pressing brush presses the lower end of the kraft paper, thus tightening the kraft paper covering the book surface. However, this process is divided into two steps: packaging and tightening. This makes the overall packaging process lengthy, resulting in reduced packaging efficiency and affecting the usability. Utility Model Content

[0004] The purpose of this invention is to provide a paper wrapping mechanism to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a paper wrapping mechanism, including a base frame, with wrapping mechanisms installed at the top of both sides of the base frame, a paper-pulling assembly connected between the two wrapping mechanisms, a driving component drivingly connected to the two wrapping mechanisms, a conveying mechanism installed at the middle of the top of the base frame, a feeding assembly installed on the side of the base frame near the discharge end of the conveying mechanism, a guide roller rotatably mounted on the base frame at the interval between the conveying mechanism and the feeding assembly, and a gap provided between the guide roller and the discharge end of the conveying mechanism for the paper-pulling assembly to pass through.

[0006] The aforementioned components achieve the following effects: the conveying mechanism can transport books and wrapping paper to the base frame. At this time, the books are located at the top front of the paper and are pressed firmly at the feeding end of the conveying mechanism. When the conveying mechanism transports the books to the center, the drive unit drives the paper-pulling assembly between the wrapping mechanism to move around the conveying mechanism, thereby pushing the paper to flip and wrap around the outside of the book. When the paper-pulling assembly moves to below the gap between the guide roller and the conveying mechanism, it can guide the tail end of the paper under the book. Then, the conveying mechanism transports the wrapped book towards the guide roller. At this time, the paper-pulling assembly can cooperate with the side of the conveying mechanism to press the drooping tail end of the paper. The conveying mechanism uses friction damping to pull the pressed drooping tail end of the paper downward. The book's guiding force can be used to perform a synchronous tightening action until the tail end of the paper is filled under the book with the help of the guide roller and the conveying assembly, making it convenient to use.

[0007] Preferably, the wrapping mechanism includes a side frame fixed to the top of the base frame, and a plurality of annularly arranged sprockets are rotatably mounted between the side frame and the inner side of the base frame. Chains are driven between the plurality of sprockets, and the paper-pulling assembly is fixed between two of the chains. A drive shaft is fixed between two sprockets located on both sides of the base frame, and one of the sprockets is drivenly connected to the drive component.

[0008] The effect achieved by the above components is that the drive unit can work with the sprocket to drive the chain, thereby achieving the purpose of driving the paper-shifting assembly.

[0009] Preferably, the paper-pulling assembly includes wrapping rods, with corner blocks connected to the chain fixed to the ends of the two wrapping rods, and brush bristles provided on one side of the wrapping rods.

[0010] The aforementioned components achieve the following effects: the corner blocks facilitate the installation of the wrapping rod between the two chains, and the bristles work together to move the paper, causing the paper to wrap around the book. When the wrapping rod moves to the area below the gap between the guide roller and the conveying mechanism, the bristles can prevent excessive contact between the paper and the conveying mechanism, thus preventing tearing during the tightening process.

[0011] Preferably, the driving component includes a drive motor fixed to one side of the base frame, and a pulley assembly is connected between the output shaft of the drive motor and the sprocket end shaft.

[0012] The effect achieved by the above components is that the drive motor can work with the pulley assembly to drive the winding mechanism.

[0013] Preferably, the conveying mechanism includes a bracket fixed at the center of the top of the base frame, a plurality of winding rollers are rotatably mounted on the bracket, a conveyor belt is driven sleeved on the outside of the winding rollers, and a conveyor motor is drivenly connected to the end shaft of one of the winding rollers.

[0014] The effect achieved by the above components is that the conveyor motor can work with the winding roller to transport the books by the conveyor belt, and the conveyor belt can pull and tighten the tail end of the paper with the brush bristles pressed against it, which is convenient and fast.

[0015] This utility model provides an improved paper wrapping mechanism, which has the following improvements and advantages compared with the prior art:

[0016] This invention uses a paper-pulling assembly to work with the conveying mechanism to press the drooping end of the paper against the side. The conveying mechanism uses frictional damping to pull the pressed end of the drooping paper downwards. The book's guiding force can be used to tighten the paper simultaneously until the paper end is filled into the bottom of the book with the help of the guide roller and the conveying assembly, making it convenient to use.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved paper wrapping mechanism. The technical solution of this utility model is as follows:

[0025] In embodiments of this utility model, such as Figures 1-3 As shown, a paper wrapping mechanism includes a base frame 1. Wrapping mechanisms 3 are installed at the top of both sides of the base frame 1. Each wrapping mechanism 3 includes a side frame 31 fixed to the top of the base frame 1. Multiple annularly arranged sprockets 33 are rotatably mounted between the side frame 31 and the inner side of the base frame 1. Chains 32 are driven between the multiple sprockets 33. A paper-feeding assembly 4 is fixed between two chains 32. A drive shaft is fixed between two sprockets 33 located on both sides of the base frame 1. One of the sprockets 33 is connected to a drive component 7. The drive component 7, in conjunction with the sprocket 33, drives the chain 32 to move, thereby driving the paper-feeding assembly 4. The moving part 7 includes a drive motor fixed to one side of the base frame 1. A pulley assembly is connected between the output shaft of the drive motor and the shaft of the sprocket 33. A paper-feeding assembly 4 is connected between the two winding mechanisms 3. The two winding mechanisms 3 are connected to the drive part 7. A conveying mechanism 5 is installed at the middle of the top of the base frame 1. The conveying mechanism 5 can convey the books and wrapping paper that are introduced into the base frame 1. At this time, the books are located at the top front of the paper and are pressed when they are at the feeding end of the conveying mechanism 5. The conveying mechanism 5 includes a bracket fixed at the center of the top of the base frame 1. Multiple winding rollers are rotatably mounted on the bracket. A conveying sleeve is provided on the outside of the winding rollers. The conveyor belt, with one of the winding rollers connected to a conveyor motor via its end shaft, enables the conveyor motor to work in conjunction with the winding roller to transport the books. The conveyor belt also pulls and tightens the paper tail end where the brush bristles 43 are pressed. A feeding assembly 2 is installed on the base frame 1 near the discharge end of the conveying mechanism 5. A guide roller 6, rotatably mounted on the base frame 1, is positioned between the conveying mechanism 5 and the feeding assembly 2. A gap is provided between the guide roller 6 and the discharge end of the conveying mechanism 5 for the paper-pushing assembly 4 to pass through. When the conveying mechanism 5 transports the books to the center, the drive unit 7 drives the paper-pushing assembly 4 between the winding mechanisms 3 along the conveyor belt. Mechanism 5 performs a circular motion, thereby pushing the paper to flip and wrap around the outside of the book. When the paper-pushing assembly 4 moves to below the gap between the guide roller 6 and the conveying mechanism 5, it can guide the tail end of the paper into the bottom of the book. Then, the conveying mechanism 5 conveys the wrapped book to the guide roller 6. At this time, the paper-pushing assembly 4 can cooperate with the side of the conveying mechanism 5 to press the drooping tail end of the paper. The conveying mechanism 5 uses friction damping to pull the pressed drooping tail end of the paper downward. The book's guiding force can be used to perform a synchronous tightening action until the tail end of the paper is filled into the bottom of the book with the help of the guide roller 6 and the feeding assembly 2.

[0026] The working principle of the paper wrapping mechanism provided by this utility model is as follows: The conveying mechanism 5 can convey the book and wrapping paper to the base frame 1. At this time, the book is located at the top front of the paper and is pressed when it is at the feeding end of the conveying mechanism 5. When the conveying mechanism 5 conveys the book to the center, the driving component 7 drives the paper-pulling assembly 4 between the wrapping mechanism 3 to move around the conveying mechanism 5, thereby pushing the paper to flip and wrap around the outside of the book. When the paper-pulling assembly 4 moves to below the gap between the guide roller 6 and the conveying mechanism 5, it can guide the tail end of the paper under the book. The rear conveyor 5 conveys the wrapped book to the guide roller 6. At this time, the paper-pulling assembly 4 can cooperate with the side of the conveyor 5 to press the drooping paper tail end. The conveyor belt can pull and tighten the drooping paper tail end pressed by the brush 43. The book's guiding force can be used to perform synchronous tightening until the paper tail end is filled under the book with the help of the guide roller 6 and the feeding assembly 2. When the wrapping rod 42 moves to the gap between the guide roller 6 and the conveyor 5, the brush 43 can prevent the paper from contacting the conveyor 5 too much and prevent tearing during the tightening process.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
