Description

Technical Field

[0001] This invention relates to the field of paper feeding technology, and more specifically to a paper feeding friction device. Background Technology

[0002] Paper tubes are tubular objects made from paper. Most paper tubes are spiral or seamless. The production process for spiral paper tubes involves first cutting the raw paper into strips, then coating one or both sides of the paper strip with a paste made of glue and other materials. Finally, a winding machine is used to wind the paper strip coated with the paste into a paper tube. A feeding device is also needed during the process to feed the paper.

[0003] Chinese Patent Application No. CN202111128276.4 discloses a paper tube winding forming device and method, including a paper output roller, a paper feeding and gluing device, a paper mounting device, a paper cutting device, a paper feeding device, a winding device, a paper tube receiving device, and a paper tube gluing and discharging device. The paper mounting device is located on one side of the paper feeding and gluing device. The paper feeding device is located along the output direction of the paper feeding and gluing device, and the paper cutting device is located at the connection between the paper feeding and gluing device and the paper feeding device. The paper feeding device includes a paper feeding platform, a paper transfer mechanism, and a winding guide plate. The winding device is located on one side of the middle of the paper feeding platform, and the paper transfer mechanism is located at the lower part of the paper feeding platform. The paper transfer mechanism is used to move the paper on the paper feeding platform in the processing direction and to remove the paper tubes that have completed the winding operation from the winding device. The output end of the winding device is equipped with a paper tube receiving device, and the paper tube gluing and discharging device is located at the lower part of the paper tube receiving device. This patent improves winding efficiency and enables paper mounting on the paper.

[0004] However, some existing feeding devices fail to adjust the paper during the feeding process, which can lead to loose paper, paper displacement, slippage, or wrinkling. Additionally, uneven gluing can occur during the gluing process. Furthermore, inconsistent heights between multiple devices during paper transfer can cause excessive stress on the paper, making it prone to folding or tearing during feeding. In such cases, the paper surface may be damaged during paper tube manufacturing, affecting the quality of the paper tube and even the production process. Summary of the Invention

[0039] The drive assembly 21 includes a first support plate 211, a transmission rod 212, a first motor 213, and a first gear 214. The first support plate 211 is installed at one end of the top of the base plate 1. The transmission rod 212 is rotatably connected to one side of the first support plate 211. One end of the transmission rod 212 is keyed to the first motor 213 that drives the rotation. One end of the surface of the transmission rod 212 is equipped with a meshing first gear 214.

[0040] The first support plate 211, together with the second support plate 224 and the third support plate 225, supports the transmission rod 212. The transmission rod 212 facilitates the rotation of the first gear 214 and the second gear 222. The first motor 213 can drive the transmission rod 212 to rotate, and the first gear 214 and the second gear 222 facilitate meshing transmission.

[0041] The transmission assembly 22 includes a connecting bar 221, a second gear 222, a through-hole 223, a second support plate 224, and a third support plate 225. The top and bottom of the transmission rod 212 are fitted with connecting bars 221 that limit the second gear 222. The transmission rod 212 and the outer side of the connecting bar 221 are slidably connected to the second gear 222. The two ends of the second gear 222 are provided with through-holes 223. The second support plate 224 is installed at one end of the second gear 222 and is rotatably connected to the transmission rod 212. The third support plate 225 is rotatably connected to the end of the transmission rod 212 away from the first motor 213.

[0042] The connecting strip 221 facilitates the movement of the second gear 222 and the second support plate 224, while also ensuring their rotation. The second support plate 224 and the third support plate 225 enhance the support effect of the transmission rod 212.

[0043] The tension adjustment assembly 23 includes a stop bar 231, a first electric push rod 232, a connecting seat 233, a slide bar 234, a connecting plate 235, and a slide groove 236. The stop bar 231 is installed at the other end of the top of the base plate 1. The first electric push rod 232 is installed in the middle of one side of the stop bar 231. The connecting seat 233 is installed at the output end of the first electric push rod 232. The slide bar 234 is installed on both sides of the top of the base plate 1. The connecting seat 233 is slidably connected to the top of the slide bar 234. The connecting plate 235 is installed at one end of the connecting seat 233. The slide groove 236 is opened at both ends of the bottom of the connecting seat 233. The slide bar 234 slides inside the slide groove 236.

[0044] The stop bar 231 is used to fix the first electric push rod 232, while the first electric push rod 232 is used to push and pull the connecting seat 233 and the components connected thereto for horizontal movement. The connecting seat 233 can support and connect the components. The sliding fit between the slide bar 234 and the slide groove 236 is used to ensure the stable sliding of the connecting seat 233, and can also assist in the limiting work during its sliding. The connecting plate 235 is used to support and fix the second support plate 224, and can drive it to move.

[0045] The friction assembly 24 includes a bracket 241, a first friction roller 242, a vertical plate 243, and a third gear 244. The bracket 241 is installed at the other end of the top of the base plate 1, the vertical plate 243 is installed at one end of the top of the base plate 1, the first friction roller 242 is rotatably connected to the upper part of the inner side of the bracket 241 and the vertical plate 243, and the third gear 244 is installed at the front end of the first friction roller 242.

[0046] The bracket 241 and the vertical plate 243 facilitate the rotational support connection of the two sets of first friction rollers 242. The first friction rollers 242 are conducive to the frictional rotation feeding operation with the second friction rollers 264 below. When the two sets of third gears 244 are rotated by the meshing of the teeth, they will drive the two sets of second friction rollers 264 to rotate together.

[0047] The lifting assembly 25 includes a second electric push rod 251, a horizontal plate 252, and a connecting cylinder 253. The second electric push rod 251 is installed in the middle of the top two sides of the base plate 1, the horizontal plate 252 is installed at the output end of the second electric push rod 251, and the connecting cylinder 253 is rotatably connected to one side of the horizontal plate 252.

[0048] The second electric push rod 251 can push the horizontal plate 252 upward, and the horizontal plate 252 is conducive to supporting the upper components and the connecting cylinder 253, and the connecting cylinder 253 can provide rolling support for the side plate 262.

[0049] The paper pressing assembly 26 includes a sleeve plate 261, a side plate 262, a baffle 263, and a second friction roller 264. The sleeve plate 261 is installed on the top of the horizontal plate 252, the side plate 262 is slidably connected to the inside of the sleeve plate 261, the baffle 263 is installed at one end of the side plate 262 located inside the sleeve plate 261, and the second friction roller 264 is rotatably connected to the inside of the sleeve plate 261 and the side plate 262.

[0050] The sleeve plate 261 facilitates the storage of the side plate 262 and the extension of the side plate 262. The baffle plate 263 facilitates the limiting of the side plate 262 during its extension. The side plate 262 facilitates the auxiliary tension adjustment and the up-and-down transmission of the clamping force on the outside of the sleeve plate 261. The second friction roller 264 assists in friction feeding and provides stable feeding by forming a clamping force on the paper. At the same time, it can also move the right end position to form a tight tension during clamping.

[0051] Among them, the two third gears 244 are respectively connected to the first gear 214 and the second gear 222 through tooth meshing. The bottom end of the second support plate 224 is installed with the top of the connecting plate 235, and the bottom end of the third support plate 225 is installed with the top of the base plate 1. The top of the connecting cylinder 253 is in rolling contact with the bottom of the side plate 262. Openings are provided on both sides of the vertical plate 243 and both sides of the bracket 241. The connection points at both ends of the second friction roller 264 are slidably connected to the inside of the openings, which facilitates the stable connection and support between the components, thereby ensuring the stability during operation.

[0052] First, the paper is passed between the two sets of first friction rollers 242 and second friction rollers 264, and then it can be clamped, tension adjusted and friction fed.

[0053] When holding paper:

[0054] The second electric push rod 251 pushes the horizontal plate 252 to move upward. At this time, the horizontal plate 252 will drive the second friction roller 264 to move upward together through the sleeve plate 261 and the side plate 262 until the paper between the top of the second friction roller 264 and the first friction roller 242 is clamped.

[0055] Then, when adjusting the tension:

[0056] The first electric push rod 232 is used to pull the connecting seat 233 to slide on the top of the slide bar 234 and the base plate 1 in conjunction with the slide groove 236. At this time, it should be pulled to the right, that is, the first electric push rod 232 retracts until the paper is straightened. The original state of the paper is slightly loose. It is necessary to tighten it until it is taut. During the pulling process, the connecting seat 233 will move together through the connecting plate 235 to drive the second support plate 224 and the rotating connected second gear 222 to achieve tension tightening. The actual length of the connecting bar 221 can be set according to the situation.

[0057] Finally, when the paper is rubbed and fed:

[0058] The first motor 213 drives the transmission rod 212 to rotate. The rotation of the transmission rod 212 simultaneously drives the first gear 214 and the second gear 222 to rotate together. The meshing of the teeth of the first gear 214 and the second gear 222 drives the third gear 244 to rotate. The third gear 244 then causes the first friction roller 242 to rotate. When the first friction roller 242 rotates, it cooperates with the second friction roller 264 below to feed the paper between them. The cooperation between the two sets of first friction rollers 242 and second friction rollers 264 achieves the function of frictional feeding, which increases the tension, prevents the paper from becoming loose, shifting, slipping, or wrinkling, and ensures uniform coating during the glue application process.

[0059] The moving assembly 31 includes a first electric slide 311, a second electric slide 312, a fixed plate 313, and an upper roller 314. The first electric slide 311 is installed on both sides inside the top end of the base plate 1. The second electric slide 312 is installed on the top of the moving end of the first electric slide 311. The fixed plate 313 is installed on the inner side of the moving end of the second electric slide 312. The upper roller 314 is rotatably connected to the upper part of the inner side of the fixed plate 313.

[0060] The first electric slide 311 can adjust the connected components to move horizontally left and right, while the second electric slide 312 is conducive to adjusting the connected components to move vertically up and down. The fixing plate 313 is conducive to connecting the second electric slide 312 and supporting the inner components. The upper roller 314 can assist the lower roller 326 in clamping and feeding the paper.

[0061] Additionally, the clamping assembly 32 includes a second motor 321, a rotating plate 322, a telescopic rod 323, a spring 324, a connecting frame 325, and a lower roller 326. The rotating plate 322 is rotatably connected to the lower part of the inner side of the fixed plate 313. The telescopic rod 323 and the spring 324 are installed on the top of the rotating plate 322. The spring 324 is located on the outer side of the telescopic rod 323. The second motor 321 is installed on the outer side of the fixed plate 313. The output shaft of the second motor 321 is keyed to the outer end of the rotating plate 322. The lower roller 326 is rotatably connected to the inner side of the connecting frame 325. The connecting frame 325 is installed on the top of the telescopic rod 323 and the spring 324.

[0062] The second motor 321 can cause the rotating plate 322 to drive the lower roller 326 to rotate for position adjustment. The telescopic rod 323 and spring 324 can be used to elastically connect the lower roller 326, and the connecting frame 325 is conducive to playing the role of connecting the upper and lower parts.

[0063] During work, as attached Figure 9 and 10As shown;

[0064] The paper can be tightly adhered to the bottom of the upper roller 314 first, and then the output shaft of the second motor 321 drives the rotating plate 322 to rotate. Since the output shaft of the second motor 321 passes through one side of the fixed plate 313, and the rotating plate 322 and the output shaft of the second motor 321 are connected by a key, the rotating plate 322 can be driven to rotate at a constant speed by the rotation of the output shaft when the second motor 321 is started to complete the rotation operation.

[0065] As the rotating plate 322 rotates, the lower roller 326 rotates along with it via the telescopic rod 323, spring 324, and connecting frame 325 until it rotates to a position below the upper roller 314. Simultaneously, it elastically adheres to the bottom of the paper and, in conjunction with the upper roller 314, clamps the paper. Since the upper roller 314 is a rotating connection and its vertical position cannot be adjusted, when the connecting frame 325 and the lower roller 326 rotate, the telescopic rod 323 and spring 324's elasticity causes the lower roller 326 to be higher than the upper roller 314. During rotation, the lower roller 326 contacts the paper while the upper roller 314 receives force. After receiving force, the lower roller 326 pushes against the telescopic rod 323 and spring 324 through the connecting frame 325, causing them to contract. At this point, the spring 324 is compressed, and the lower roller 326 is positioned as follows: Figure 9 The state shown;

[0066] Then, after the spring 324 is elastically compressed, it will work with the upper roller 314 above to clamp the paper through the lower roller 326 under the elastic pressure. That is, the elasticity and reaction force of the spring 324 are used to form a clamping force on the paper. Then, during feeding, the first electric slide 311 moves to the left or to the processing area, and at the same time, the second electric slide 312 can be driven to move up or down. Adjusting the required height can complete the feeding operation, so that the paper is not subjected to excessive force and the paper is not easy to fold or tear during the feeding process.

[0067] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
