Description

Technical Field

[0001] This utility model relates to the technical field of tissue paper conveying equipment, and more specifically, to a tissue paper conveying mechanism. Background Technology

[0002] In the production process of portable tissue packs, folded paper and stacked tissues of a specified quantity are typically pushed into a conveyor channel for transport. However, existing tissue conveyor channels all use conveyor belt structures, which are difficult to adapt to the connection of the paper-splitting structure of the receiving roller. For example, a tissue-splitting device, tissue-splitting system and splitting method disclosed in patent document CN109704103B has a fast paper-splitting speed. In the actual equipment structure, the tissues stacked under the receiving roller cannot be directly pushed onto the conveyor belt for transport. A complex transition structure needs to be set between the receiving roller and the conveyor, which increases the equipment cost. Furthermore, during the process of transporting tissues, the tissues are prone to getting stuck in the gap between the conveyor belt and the equipment, requiring high tension accuracy of the conveyor belt. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides a paper conveying mechanism to solve the above and related problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a paper conveying mechanism, comprising: A paper-holding assembly is disposed within the machine body. The paper-holding assembly includes a paper-holding base, which is movably disposed within the machine body. At least one set of paper-holding rods is provided on one side of the paper-holding base, and the paper-holding rods are used to support the stack of paper towels. A conveying assembly is disposed at one end of the machine body near the paper support rod. The conveying assembly includes a conveying body with a conveying channel. Multiple sets of paper pushers that move along the conveying direction of the conveying channel are disposed in the conveying channel. The paper pushers push the paper towel stack on the paper support rod into the conveying channel and push the paper towel stack to move.

[0005] In the aforementioned paper feeding and conveying mechanism, two sets of paper feeding assemblies are provided. Both sets of paper feeding assemblies include a support plate. A support arm that can move up, down, left, and right is provided on the side of the support plate. A transverse paper feeding seat is provided on one side of the upper end of the support arm. Each set of paper feeding rods is provided with two rods. When the two paper feeding rods support the paper towel pile, the end of the paper feeding rod away from the conveying assembly forms a push rod area between it and the paper towel pile.

[0006] In the aforementioned paper conveying mechanism, two first slide rail sliders are longitudinally arranged on the side of the support plate. A lifting beam is connected to the first slide rail slider, and a second slide rail slider is transversely arranged on the lifting beam. Four first transmission gears arranged in a rectangular distribution are arranged between the two first slide rail sliders. The four first transmission gears are connected to each other through a first transmission chain. At least one first transmission gear is connected to a first drive motor. A bearing is installed on the first transmission chain, and the bearing is connected to the second slide rail slider through a support arm.

[0007] In the aforementioned paper conveying mechanism, the bearing section includes a connecting shaft mounted on a first transmission chain, a bearing sleeved on the connecting shaft, and the inner ring of the bearing connected to the support arm.

[0008] In the aforementioned paper conveying mechanism, at least two side baffles are provided at the upper end of the conveying body, and the conveying channel is formed between the two side baffles. A push rod hole is provided between the two side baffles on the conveying body, and the length direction of the push rod hole is arranged along the paper towel conveying direction.

[0009] In the aforementioned paper conveying mechanism, two sets of chain drive units are provided inside the conveying body. The side view projections of the two sets of chain drive units overlap and are staggered. Both sets of chain drive units include a second drive chain, and the paper pusher is hinged between the two second drive chains.

[0010] In the aforementioned paper conveying mechanism, the paper pushing part includes a push rod seat. One end of the push rod seat is provided with a first push rod, and the other end is provided with a second push rod. The first push rod and the second push rod move within the push rod hole. A first hinge shaft is provided on the side of the push rod seat near the first push rod, and a second hinge shaft is provided on the side of the push rod seat near the second push rod. The first hinge shaft and the second hinge shaft are respectively hinged to two second transmission chains.

[0011] In the aforementioned paper conveying mechanism, each of the two sets of chain drive units includes four second drive gears arranged in a rectangular shape. The four second drive gears are connected by a second drive chain. A synchronous shaft is provided below the two sets of chain drive units.

A second drive motor is provided below the synchronous shaft. The second drive motor is meshed with one of the drive gears.

[0012] The beneficial effects of this utility model are that the paper-holding rod on the paper-holding assembly moves to support the tissues and form a tissue pile. Then, by moving the tissue pile above the input end of the conveying body, the paper-pushing part can push the tissue pile on the paper-holding rod into the conveying channel during the cyclical movement of the conveying channel. The paper-pushing part pushes the tissue pile, eliminating the need for the tissue pile to contact the conveyor belt for conveying. This effectively reduces the phenomenon of paper jams during the conveying process. Moreover, the paper-holding assembly can better cooperate with the conveying assembly. The overall structure is relatively simple, making it convenient to receive, push away, and convey tissues falling from above, effectively reducing equipment costs. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Combination Figures 1 to 7 The paper-holding and conveying mechanism shown includes a paper-holding assembly 2 and a conveying assembly 3. The paper-holding assembly 2 is disposed inside the machine body 1 and includes a paper-holding seat 5, which is movably disposed inside the machine body 1. At least one set of paper-holding rods 6 are provided on one side of the paper-holding seat 5, and the paper-holding rods 6 are used to support the tissue stack 21. The conveying assembly 3 is disposed at one end of the machine body 1 near the paper-holding rods 6. The conveying assembly 3 includes a conveying body 16, which is provided with a conveying channel. Multiple sets of paper-pushing parts that move along the conveying direction of the conveying channel are provided in the conveying channel. The paper-pushing parts push the tissue stack 21 on the paper-holding rods 6 into the conveying channel, and the paper-pushing parts push the tissue stack 21 to move. In this embodiment, the paper-supporting rod 6 on the paper-supporting assembly moves to support the tissues and form a tissue pile 21. Then, by moving the tissue pile 21 above the input end of the conveying body 16, the paper-pushing part can push the tissue pile 21 on the paper-supporting rod 6 into the conveying channel during the cyclical movement of the conveying channel. The paper-pushing part pushes the tissue pile 21, eliminating the need for the tissue pile 21 to contact the conveyor belt for conveying. This effectively reduces the phenomenon of paper jams during the conveying process. Moreover, the paper-supporting assembly 2 can better cooperate with the conveying assembly 3. The overall structure is relatively simple, making it convenient to receive and push away the tissues falling from above and convey them, effectively reducing equipment costs.

[0023] In this embodiment, two sets of paper-holding components 2 are arranged side to side to allow the paper-holding rods 6 of the two sets to alternately receive the falling tissues. Each set of paper-holding components 2 includes a support plate 4. A support arm 15 that can move up, down, left, and right is provided on the side of the support plate 4. A horizontal paper-holding seat 5 is provided on one side of the upper end of the support arm 15. Each set of paper-holding rods 6 has two rods. When the two paper-holding rods 6 support the tissue pile 21, the end of the paper-holding rod 6 away from the conveying component 3 forms a push rod area with the tissue pile 21. After the paper-holding rods 6 receive the falling tissues and stack them into a tissue pile 21, the paper-holding rods 6 move the tissue pile 21 to the input end of the conveying body 16. The paper-pushing part runs back and forth in the conveying body 16 until it moves to the input end and can be inserted into the push rod area. During further movement, the tissue pile 21 is pushed into the conveying channel and pushed forward. The structure is relatively simple.

[0024] In this embodiment, two first slide rail sliders 7 are longitudinally arranged on the side of the support plate 4. A lifting beam 8 is connected to the first slide rail slider 7, and a second slide rail slider 9 is arranged laterally on the lifting beam 8. Four first transmission gears 10 arranged in a rectangular pattern are arranged between the two first slide rail sliders 7. The four first transmission gears 10 are connected to each other through a first transmission chain 11. One of the first transmission gears 10 is connected to a first drive motor 12. A bearing is installed on the first transmission chain 11, and the bearing is connected to the second slide rail slider 9 through a support arm 15. The first drive motor 12 drives one of the first transmission gears 10 to rotate, thereby driving the first transmission chain 11 to run, so that the support arm 15 drives the paper-holding rod 6 to move up, down, left, and right, so that the two sets of paper-holding rods 6 can alternately receive the falling paper towels and alternately send the paper towel pile 21 into the conveying channel.

[0025] The bearing section includes a connecting shaft 13 mounted on the first transmission chain 11, and a bearing 14 sleeved on the connecting shaft 13. The inner ring of the bearing 14 is connected to the support arm 15. When the support arm 15 moves upward, the outer ring of the bearing 14 can contact the lower end face of the lifting beam 8. During subsequent left and right movements, the outer ring rolls under the friction of the lifting beam 8, reducing friction and making the operation smoother.

[0026] In this embodiment, the upper end of the conveying body 16 is provided with at least two side baffles 17, and a conveying channel is formed between the two side baffles 17. A push rod hole 18 is provided between the two side baffles 17 on the conveying body 16. The length direction of the push rod hole 18 is arranged along the conveying direction of the paper towel pusher 21. The side baffles 17 can prevent the paper towel stack 21 from swaying left and right and becoming loose during the conveying process, and the push rod hole 18 can facilitate the movement of the paper pusher.

[0027] Specifically, in this embodiment, the conveying body 16 is provided with two sets of chain drive units. The side view projections of the two sets of chain drive units are overlapping and staggered. Both sets of chain drive units include a second drive chain 23. The paper pusher is hinged between the two second drive chains 23. The paper pusher is a strip-shaped structure. The two sides of the paper pusher are hinged to the corresponding second drive chains 23, which can facilitate the smooth switching of the up and down positions at the corner.

[0028] The paper pushing unit includes a push rod seat 24. One end of the push rod seat 24 is provided with a first push rod 19, and the other end is provided with a second push rod 20. The first push rod 19 and the second push rod 20 move within a push rod hole 18. A first hinge shaft 25 is provided on the side of the push rod seat 24 near the first push rod 19, and a second hinge shaft 26 is provided on the side of the push rod seat 24 near the second push rod 20. The first hinge shaft 25 and the second hinge shaft 26 are respectively hinged to two second transmission chains 23. The push rod seat 24 is strip-shaped, and the push station for each tissue stack 21 is formed between the first push rod 19 and the second push rod 20. The side view projection of the drive chain 23 is an overlapping and staggered arrangement, that is, the two sides of the two second drive chains 23 do not overlap, forming one in front and one behind. When the push rod seat 24 moves to the edge, the hinge shaft in front moves down / up first. At this time, the push rod seat 24 swings down / up until the hinge shaft on the other side reaches the edge and moves down, and finally the push rod seat 24 smoothly switches between the up and down positions. Because this structure allows the push rod seat 24 to swing when moving to the side, it is convenient for the first push rod 19 or the second push rod 20 to extend into the push rod area and push the tissue stack 21 into the conveying channel. The structure is simple and more practical.

[0029] Specifically, in this embodiment, each of the two sets of chain drive units includes four second drive gears 22 arranged in a rectangular shape. The four second drive gears 22 are connected by a second drive chain 23. A synchronous shaft 27 is provided below the two sets of chain drive units. A drive gear 28 is provided at both ends of the synchronous shaft 27. The two drive gears 28 are respectively meshed with one of the second drive gears 22 in the two sets of chain drive units. A second drive motor 29 is provided below the synchronous shaft 27. The second drive motor 29 is meshed with one of the drive gears 28. The second drive motor 29 can drive the two sets of second drive chains 23 to move synchronously, so as to facilitate the movement of the push rod seat 24 and improve smoothness.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
