Description

Technical Field

[0001] This utility model relates to the field of paper feeder technology, specifically to a paper feeding structure that reduces maintenance difficulty and facilitates paper feeding. Background Technology

[0002] Shared tissue dispensers are a common device found in some public places. Users scan a QR code on the device to obtain tissues. In 2024, the applicant applied for an invention patent for a tissue dispenser, aiming to provide a new type of tissue dispenser for more convenient tissue access. However, after the product was launched on the market and underwent a period of use and maintenance, certain problems were discovered. When the tissues in the dispenser are used up, maintenance personnel need to open the front door of the dispenser to reload tissues, inserting the ends of the tissues into the dispensing mechanism so that the tissues can be directly conveyed after the device is started.

[0003] However, after a long period of maintenance, it was found that during the process of inserting the paper towel into the paper output mechanism, the paper towel would get stuck in the conveyor channel and could not be smoothly pushed into the conveyor component used to transport the paper towel. It was necessary to pull the paper towel out of the conveyor channel and then push it back in for reloading. This process often required multiple attempts to successfully push the paper towel into the conveyor component and complete the reloading of the paper towel.

[0004] Therefore, there is an urgent need for a new structure that can reduce the difficulty of operation and maintenance and facilitate paper feeding, in order to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a paper feeding structure that reduces maintenance difficulty and facilitates paper feeding. To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0006] A paper feeding structure that reduces maintenance difficulty and facilitates paper feeding includes an installation cavity disposed within a housing, and a paper dispensing mechanism assembled within the installation cavity for conveying and cutting continuously packaged paper towels one by one. The paper dispensing mechanism includes a conveying channel defined by two opposing side plates, and a conveying component and a cutting component are arranged sequentially along the conveying direction of the conveying channel. A paper feeding port for paper towels to pass through is provided at the upper part of the installation cavity.

[0007] The upper end of the conveying channel is provided with a first guide member, which is arranged facing the paper feeding port and has a first guide surface facing the paper feeding port and having an inwardly concave arc surface.

[0008] A second guide is also provided at the upper end of the conveying channel. The second guide is provided in a manner corresponding to the first guide and has a second guide surface that protrudes from the arc surface toward the first guide surface.

[0009] The first guide surface and the second guide surface define the inlet end of the conveying channel, and the inlet end is connected to the paper feeding port.

[0010] Furthermore, the width of the inlet end is gradually reduced from the opening end towards the conveying assembly.

[0011] Furthermore, the first guide includes a main body, and one end of the main body facing the paper feed port is formed with a paper receiving portion extending in the direction of the paper feed port, and the surface of the paper receiving portion facing the paper feed port is located at the upper end of the paper feed port.

[0012] Furthermore, an inclined clearance surface is provided above the end of the paper receiving part facing the paper feed port.

[0013] Furthermore, the main body is provided with a docking part at one end corresponding to the conveying channel, the docking part extending toward the conveying channel and docking with the conveying channel.

[0014] Furthermore, the conveying assembly is located downstream of the paper feed port. The conveying assembly includes a driving roller and a driven roller arranged opposite to each other, and a conveying drive device for driving the driving roller to rotate. The driving roller and the driven roller are defined by a conveying gap corresponding to the conveying channel.

[0015] Furthermore, the length of the portion of the conveying channel located on the lower side of the conveying assembly is approximately the same as the length of the inlet end.

[0016] Furthermore, a wide opening is provided at the outlet of the end of the conveying channel. The upper end of the wide opening is connected to the end of the conveying channel, and the wide opening extends downward. The width of the wide opening is greater than the width of the conveying channel.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this embodiment, a first guide and a second guide are provided at the upper end of the conveying channel of the paper dispensing mechanism, and a first lower guide surface with an inwardly concave curved surface and a second guide surface with an outwardly convex curved surface are respectively provided. At the same time, the conveying component is arranged on the lower side adjacent to the first guide. During the reloading of the paper towel, the paper towel can enter the conveying channel along the inlet end defined by the first and second guide surfaces. The arrangement of the conveying component and the first guide allows the paper towel to directly enter the conveying component after passing the inlet end and be conveyed by the conveying component, thereby completing the reloading action of the paper towel. During the reloading and conveying of the paper towel, the paper towel can be guided by the first and second guide surfaces, thereby avoiding jamming in the conveying channel. At the same time, placing the conveying component on the lower side adjacent to the first guide can shorten the distance between the conveying component and the inlet end, reduce the movement of the paper towel in the conveying channel, and reduce the probability of jamming.

Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0025] In this embodiment, a first guide member 210 and a second guide member 220 are provided at the upper end of the conveying channel 202 of the paper output mechanism 200, and a first lower guide surface with an inwardly concave curved surface and a second guide surface 221 with an outwardly convex curved surface are respectively provided. Meanwhile, the conveying assembly 300 is positioned on the lower side adjacent to the first guide member 210. During the reassembly of the paper towel 104, the paper towel 104 can enter the conveying channel 202 along the inlet end 203 defined by the first guide surface 211 and the second guide surface 221. Furthermore, the arrangement of the conveying assembly 300 and the first guide member 210 adjacent to each other allows the paper towel 104 to... After passing through the inlet end 203, the tissue 104 directly enters the conveying component 300 and is conveyed by the conveying component 300, thereby completing the reloading action of the tissue 104. During the reloading and conveying process of the tissue 104, the tissue 104 can be guided by the first guide surface 211 and the second guide surface 221, thereby avoiding the situation of getting stuck in the conveying channel 202. At the same time, by setting the conveying component 300 on the lower side adjacent to the first guide 210, the distance between the conveying component 300 and the inlet end 203 can be shortened, reducing the movement of the tissue 104 in the conveying channel 202 and reducing the probability of getting stuck.

[0026] Specifically, such as Figure 1-4 As shown, this utility model embodiment provides a paper feeding structure that reduces maintenance difficulty and facilitates paper feeding. It includes an installation cavity 101 within a housing 100, and a paper dispensing mechanism 200 assembled within the installation cavity 101, which conveys and cuts continuously packaged paper towels 104 one by one. The paper dispensing mechanism 200 includes a conveying channel 202 defined by two opposing side plates 201, and a conveying assembly 300 and a cutting assembly 400 are sequentially arranged along the conveying direction of the conveying channel 202. A paper feeding port 102 for the paper towels 104 to pass through is provided at the upper part of the installation cavity. Simultaneously, the conveying channel... A first guide member 210 is provided at the upper end of the conveying channel 202. The first guide member 210 is positioned facing the paper feed port and has a first guide surface 211 facing the paper feed port and having an inwardly concave arc surface. A second guide member 220 is also provided at the upper end of the conveying channel 202. The second guide member 220 is positioned corresponding to the first guide member 210 and has a second guide surface 221 protruding from the first guide surface 211. The first guide surface 211 and the second guide surface 221 define the inlet end 203 of the conveying channel 202, and the inlet end 203 is connected to the paper feed port 102.

[0027] In this embodiment, a feeding bin 103 is also provided inside the housing 100, located next to the mounting cavity 101, for storing bagged tissues 104 that are connected end to end into a long strip. When the tissues 104 are used up, the paper feeder needs to be refilled with tissues 104 into the feeding bin 103. In this embodiment, a door panel 106 is also provided on the housing 100 to cover the mounting cavity 101 and the feeding bin 103. When reloading the tissues 104, the upper end of the tissues 104 is inserted into the conveying assembly 300 along the inlet end 203 to complete the feeding operation, so that the conveying assembly 300 can convey the tissues 104 when the equipment is started. During this process, the end of the tissue 104 passes through the paper feed port 102. The first guide surface 211 is set as a concave curved surface, which can guide the tissue 104 downward (that is, in the direction of the conveying channel 202). At the same time, the second guide surface 221 is set as a convex curved surface. When the tissue 104 is blocked and guided by the first guide surface 211, it can restrict the flipping direction of the tissue 104, so that it can be pushed between the first guide surface 211 and the second guide surface 221, and can be smoothly guided downward. In this process, the tissue 104 can be pushed more smoothly, avoiding jamming, reducing the difficulty for maintenance personnel in the process of loading and maintaining paper, and improving the convenience of paper feeding.

[0028] In this embodiment, in order to more accurately convey the tissue 104 toward the conveying channel 202 and the conveying component 300, the width of the inlet end 203 is gradually reduced from the opening end toward the conveying component 300.

[0029] To ensure that the tissue 104 can smoothly enter the inlet 203 after passing through the paper feed port 102, the first guide member 210 includes a main body 212. At the end of the main body 212 facing the paper feed port 102, a receiving portion 213 is formed, extending towards the paper feed port 102. The surface of the receiving portion 213 facing the paper feed port 102 is located at the upper end of the paper feed port 102. When the tissue 104 passes through the paper feed port 102, it is restricted by the inner surface of the receiving portion 213, thus entering the inlet 203 under the guidance of the inner surface. It is understood that the inner surface of the receiving portion 213 is also part of the first guide surface 211; specifically, the portion near the paper feed port 102 is used to mate with the paper feed port 102, thereby receiving the tissue 104 passing through the paper feed port 102 and guiding it smoothly into the inlet 203.

[0030] To prevent the tissue paper 104 from getting stuck at the end of the paper receiving part 213, an inclined clearance surface 214 is provided on the end of the paper receiving part 213 facing the paper feed port 102. After the tissue paper 104 passes through the paper feed port 102, if it is blocked by the end of the paper receiving part 213, it slides downward along the inclined clearance surface 214 and enters the inlet end 203.

[0031] To ensure a smooth connection between the inlet end 203 and the conveying channel 202, a docking part 215 is provided at the end of the main body 212 corresponding to the conveying channel 202. The docking part 215 extends towards the conveying channel 202 and docks with it. By docking the docking part 215 with a side plate 201 of the conveying channel, the gap in the conveying channel 202 is reduced, allowing the paper towel 104 to move more smoothly along the inlet end 203 and the conveying channel 202, reducing the possibility of jamming.

[0032] To further improve the smoothness of tissue paper conveying 104, a conveying assembly 300 is located downstream of the paper feed inlet. The conveying assembly 300 includes a driving roller 301 and a driven roller 302 arranged opposite each other, and a conveying drive device 303 that drives the driving roller 301 to rotate. The driving roller 301 and the driven roller 302 define a conveying gap corresponding to the conveying channel 202. With this structure, after passing through the inlet end 203, the tissue paper 104 directly enters the conveying gap formed by the driving roller 301 and the driven roller 302, and under the drive of the conveying drive device 303, the two rollers roll against each other to convey the tissue paper 104.

[0033] In order to improve the reliability of the paper towel 104 during the conveying process, the length of the conveying channel 202 is reduced as much as possible to minimize the possibility of the paper towel 104 getting stuck. In this embodiment, the length of the portion of the conveying channel 202 located below the conveying assembly 300 is approximately the same as the length of the inlet end 203.

[0034] After the tissue paper 104 is conveyed out, it can quickly flow out of the conveying channel 202, and avoid excessive shaking of the tissue paper 104, which would interfere with other parts of the paper feeder. A wide opening 204 is provided at the outlet of the conveying channel. The upper end of the wide opening 204 is connected to the end of the conveying channel 202, and the wide opening 204 extends downwards. The width of the wide opening 204 is greater than the width of the conveying channel 202. After the tissue paper 104 flows out of the end of the conveying channel 202, it is restricted by the wide opening 204, thereby reducing the shaking of the tissue paper 104. Then, the cutting component 400 cuts it into sections and it falls towards the discharge port. The user then removes the tissue paper 104 along the discharge port.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
