Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene product production equipment, and in particular to a conveying device for paper towel production. Background Technology

[0002] In tissue paper processing, tissue paper conveying typically refers to the process of transferring tissue paper from one step on the production line to the next, or transporting stacks of tissue paper from the production line to the packaging area. However, in existing technologies, after cutting and pressing, the stacks of tissue paper are conveyed by a conveyor for packaging. Because the stacks of tissue paper after cutting and pressing are relatively soft, they are prone to shifting and wrinkling when entering the conveyor, making it difficult to ensure the flatness of the tissue paper and affecting the appearance and quality of the final product. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model provides a conveying device for paper towel production, which mainly solves the problems of poor conveying stability and low conveying quality of existing paper towel conveying devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A conveying device for paper towel production includes a frame, a first conveying mechanism, a second conveying mechanism, a first drive motor, a second drive motor, a first transmission mechanism, a second transmission mechanism, a guiding mechanism, a spacing adjustment mechanism, and a pressing mechanism. The first conveying mechanism includes two parallel first conveyor belt assemblies, with a first conveying channel for accommodating paper towels formed between adjacent first conveyor belt assemblies. The first drive motor is connected to the two first conveyor belt assemblies via the first transmission mechanism. The guiding mechanism is located at the input end of the first conveying mechanism and includes two guide plates with adjustable spacing for guiding the paper towels into the first conveying channel. The spacing adjustment mechanism is located at the output end of the first conveying mechanism and includes an adjusting frame on the frame, a bottom conveyor belt below the adjusting frame, and a pressing mechanism. The structure includes a drive cylinder at the top of the frame, a lifting frame at the bottom of the drive cylinder, a top conveyor belt on the lifting frame, and two side conveyor belts on both sides of the bottom conveyor belt. The top conveyor belt is inclined and gradually slopes downward from the first conveying mechanism to the second conveying mechanism. Flexible baffles are provided on the two side conveyor belts. The second conveying mechanism is located at the output end of the spacing adjustment mechanism. The second conveying mechanism includes two parallel second conveyor belt assemblies. A second conveying channel for accommodating paper towels is formed between two adjacent second conveyor belt assemblies. The second drive motor is connected to the two second conveyor belt assemblies through a second transmission mechanism. The pressing mechanism is located at the output end of the second conveying mechanism. The pressing mechanism includes at least one set of pressing rollers for applying pressure to the paper towels during conveying to maintain their flatness.

[0006] Furthermore, the pressing mechanism also includes a mounting frame and an elastic element. The pressing roller is rotatably mounted on the mounting frame, and the elastic element is disposed between the mounting frame and the frame to provide an elastic force that causes the pressing roller to press the paper towel.

[0007] Furthermore, the elastic element is a spring or a cylinder, and the surface of the pressure roller is covered with a flexible material layer.

[0008] Furthermore, the two guide plates are mounted on the frame via slide rails, and the guide plates are connected to adjusting screws. The distance between the two guide plates can be adjusted by rotating the adjusting screws. The input end of the guide plate is provided with an arc-shaped guide section.

[0009] Furthermore, the surfaces of the bottom conveyor belt and the top conveyor belt are provided with anti-slip textures, which are raised dots or grooves.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This paper towel production conveying device, by setting up a frame, a first conveying mechanism, a second conveying mechanism, a first drive motor, a second drive motor, a first transmission mechanism, a second transmission mechanism, a guiding mechanism, a spacing adjustment mechanism, and a pressing mechanism, forms a complete and efficient paper towel conveying system. The various mechanisms work together to stably and orderly convey paper towels from the input end to the output end, thereby improving production efficiency. Specifically, the first conveying mechanism adopts two parallel first conveyor belt assemblies to form a first conveying channel. This structure enables the paper towels to maintain a relatively stable posture during the conveying process, reducing deviation. The first drive motor is connected to two first conveyor belt assemblies via a first transmission mechanism, ensuring the consistency and stability of the conveying power and guaranteeing smooth transport of tissues. Furthermore, a guiding mechanism located at the input end of the first conveying mechanism, with two adjustable guide plates, accurately guides tissues of different sizes into the first conveying channel, improving the device's adaptability to different sizes of tissues and reducing conveying malfunctions caused by inaccurate tissue entry into the conveying channel. Simultaneously, a spacing adjustment mechanism located at the output end of the first conveying mechanism, through the coordination of an adjusting frame, bottom conveyor belt, drive cylinder, lifting frame, top conveyor belt, and side conveyor belts, allows for flexible adjustment of the spacing between tissue stacks according to packaging and conveying requirements. The inclined distribution of the top conveyor belts facilitates a smooth transition of tissues from the first to the second conveying mechanism. Meanwhile, flexible baffles on the side conveyor belts prevent lateral shifting of tissues during transport and allow for spacing adjustments, ensuring conveying accuracy. Finally, a pressing mechanism located at the output end of the second conveying mechanism, with at least one set of pressing rollers, applies pressure to the transported tissues, effectively maintaining their flatness, preventing wrinkles, and improving the quality of the final product.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] The embodiment of this utility model is as follows:

The first conveying mechanism 2 includes two parallel first conveyor belt assemblies 21, forming a first conveying channel 22 for accommodating paper towels between adjacent first conveyor belt assemblies 21. The first drive motor 4 is connected to the two first conveyor belt assemblies 21 via the first transmission mechanism 5. The guiding mechanism 6 is located at the input end of the first conveying mechanism 2 and includes two guide plates 61 with adjustable spacing for guiding the paper towels into the first conveying channel 22. The spacing adjustment mechanism 7 is located at the output end of the first conveying mechanism 2 and includes an adjusting frame 71 on the frame 1, a bottom conveyor belt 72 located below the adjusting frame 71, and a pressing mechanism 8. The structure includes a drive cylinder 73 on the upper part of the frame 71, a lifting frame 74 at the lower end of the drive cylinder 73, a top conveyor belt 75 on the lifting frame 74, and two side conveyor belts 76 on the lateral sides of the bottom conveyor belt 72. The top conveyor belt 75 is inclined and gradually slopes downward from the first conveying mechanism 2 to the second conveying mechanism 3. Flexible baffles 77 are correspondingly provided on the two side conveyor belts 76. The second conveying mechanism 3 is located at the output end of the spacing adjustment mechanism 7. The second conveying mechanism 3 includes two parallel second conveyor belt assemblies 31. A second conveying channel 32 for accommodating paper towels is formed between two adjacent second conveyor belt assemblies 31. The second drive motor is connected to the two second conveyor belt assemblies 31 through a second transmission mechanism. The pressing mechanism 8 is located at the output end of the second conveying mechanism. The pressing mechanism 8 includes at least one set of pressing rollers 81 for applying pressure to the paper towels during conveying to maintain their flatness.

[0018] This tissue paper production conveying device, through the arrangement of a frame 1, a first conveying mechanism 2, a second conveying mechanism 3, a first drive motor 4, a second drive motor 5, a first transmission mechanism 5, a second transmission mechanism 6, a guiding mechanism 6, a spacing adjustment mechanism 7, and a pressing mechanism 8, forms a complete and efficient tissue paper conveying system. The various mechanisms work together to stably and orderly convey tissue paper from the input end to the output end, improving production efficiency. Specifically, the first conveying mechanism 2 uses two parallel first conveyor belt assemblies 21 to form a first conveying channel 22. This structure allows the tissue paper to maintain a relatively stable posture during conveying, reducing deviation. The first drive motor 4 is connected to the two first conveyor belt assemblies 21 through the first transmission mechanism 5, ensuring the consistency and stability of the conveying power and ensuring smooth tissue paper delivery. Furthermore, the guiding mechanism 6 is located at the input end of the first conveying mechanism 2, and its two adjustable guide plates 61 can accurately guide tissue paper of different sizes. The first conveying channel 22 improves the device's adaptability to different sizes of tissues, reducing conveying failures caused by inaccurate tissue entry into the conveying channel. Simultaneously, the spacing adjustment mechanism 7, located at the output end of the first conveying mechanism 2, allows for flexible adjustment of the spacing between tissue stacks based on packaging and conveying requirements through the coordination of the adjusting frame 71, bottom conveyor belt 72, drive cylinder 73, lifting frame 74, top conveyor belt 75, and side conveyor belt 76. The top conveyor belt 75 is inclined, facilitating a smooth transition of tissues from the first conveying mechanism 2 to the second conveying mechanism 3. Meanwhile, the flexible baffles 77 on the side conveyor belt 76 prevent lateral shifting of tissues during conveying and adjust the spacing, ensuring conveying accuracy. Furthermore, the pressing mechanism 8, located at the output end of the second conveying mechanism 3, applies pressure to the tissues during conveying, effectively maintaining their flatness, preventing wrinkles, and improving the quality of the final product.

[0019] In this embodiment, the pressing mechanism 8 further includes a mounting frame 82 and an elastic element 83. The pressing roller 81 is rotatably mounted on the mounting frame 82, and the elastic element 83 is disposed between the mounting frame 82 and the frame 1 to provide elastic force for the pressing roller 81 to press the paper towel. This design allows the pressing roller to automatically adjust the pressing degree according to the thickness of the paper towel stack. The elastic force provided by the elastic element 83 ensures that the pressing roller always applies appropriate pressure to the paper towel, ensuring the flatness of the paper towel without damaging it due to excessive pressure. This further improves the reliability and applicability of the conveying device. Furthermore, the elastic element 83 is a spring or a cylinder, preferably a spring. The surface of the pressing roller 81 is covered with a flexible material layer 84, which can reduce the friction between the pressing roller 81 and the paper towel, avoiding scratching the paper towel surface due to excessive friction. At the same time, the flexible material layer 84 can better fit the paper towel surface, improve the pressing effect, and further improve the flatness and quality of the paper towel.

[0020] Furthermore, the two guide plates 61 are mounted on the frame 1 via slide rails 62, and each guide plate 61 is connected to an adjusting screw 63. The distance between the two guide plates 61 can be adjusted by rotating the adjusting screw 63. The input end of each guide plate 61 has an arc-shaped guide portion 64. Rotating the adjusting screw 63 allows for convenient and quick adjustment of the distance between the two guide plates 61. This design allows operators to quickly adjust the guiding mechanism 6 according to different sizes of tissue paper, improving production efficiency and device flexibility. The arc-shaped structure of the guide portion 64 also guides the tissue paper more smoothly between the two guide plates 61, reducing jamming and collisions when the tissue paper enters the guiding mechanism 6, further improving the stability and accuracy of the conveying process.

[0021] Furthermore, the surfaces of the bottom conveyor belt 72 and the top conveyor belt 75 are provided with anti-slip textures 78, which are raised dots or grooves, preferably raised dots, which can increase the friction between the conveyor belt and the paper towel, prevent the paper towel from slipping during the conveying process, ensure that the paper towel can be conveyed stably and continuously, and further improve the reliability and conveying quality of the conveying device.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
