Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone back cover production, and specifically provides an integrated device for efficient coiling, gluing, skin pasting and cutting. Background Art

[0002] A vegan leather mobile phone back cover is a mobile phone back cover made of artificial synthetic leather soft material, which has many advantages. It simulates the softness and warmth of genuine leather, has a skin-friendly feel, and does not cause discomfort to the hand even after long-term use. It can also provide a warm touch and is not easy to slip; in terms of aesthetics, the vegan leather back cover can create a low-key luxury feeling, and its natural texture and color add unique personality to the mobile phone; in terms of durability, it is more scratch-resistant than metal and glass, can resist daily wear and tear to a certain extent, is not easy to stain with fingerprints and stains, and is easy to clean and maintain; in addition, the vegan leather back cover has less impact on the environment during the production process, which conforms to the concept of environmental protection and sustainable development.

[0003] There are still many areas for improvement in the current processing flow of mobile phone vegan leather back covers. In the existing processing mode, the leather material needs to be processed by a variety of devices in sequence. These devices have single functions and low integration. After a series of processing procedures are completed, the cut leather material still needs to be pasted onto the mobile phone back cover with glue. Due to the low integration of the devices, each device has its own independent body and operation space. In actual processing, a large amount of space has to be occupied to place these various processing devices. This not only requires a very large area for the production site but also increases the space cost of the factory; moreover, the entire processing step is carried out separately, and the transfer of the leather material between each processing link depends on the conveying structure and is conveyed from one device to another. Each time the leather material is conveyed, actions such as waiting and positioning are involved, and a large amount of time is thus wasted in the back-and-forth conveying of the leather material. The actual processing cycle of the entire mobile phone vegan leather back cover is significantly lengthened, seriously affecting the production efficiency and increasing the production cost of the enterprise. For this reason, we propose an integrated device for efficient coiling, gluing, skin pasting and cutting. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the present invention provides an integrated device for efficient coiling, gluing, skin pasting and cutting, which solves the problem that the entire processing step of the existing mobile phone back cover production is carried out separately, and the transfer of the leather material between each processing link depends on the conveying structure and is conveyed from one device to another. Each time the leather material is conveyed, actions such as waiting and positioning are involved, and a large amount of time is thus wasted in the back-and-forth conveying of the leather material. The actual processing cycle of the entire mobile phone vegan leather back cover is significantly lengthened, seriously affecting the production efficiency and increasing the production cost of the enterprise.

[0072] Among them, the connecting flange 42 is internally connected to the storage tank 41, the connecting flange 42 is internally connected to the hose pump 44, the hose pump 44 is internally connected to the conduit 45, and the conduit 45 is internally connected to the coater 47. By using the cooperation between the hose pump 44 and the connecting flange 42, the glue stored in the storage tank 41 can be pumped into the conduit 45, so that the conduit 45 can send the glue to the coater 47.

[0073] Working principle of the present invention: during processing, the motor 2 313 and the cylinder 214 are powered on and enter the standby state, the cylinder 214 is powered on to push the connecting frame 215 downward, the connecting frame 215 pushes the cutter 1 216, the cutter 1 216 cooperates with the connecting square column 217 to push the cutter 2 218, so that the cutter 2 218 moves synchronously with the cutter 1 216, the cutter 1 216 and the cutter 2 218 move downward synchronously during the movement, and cut the leather material 6 located on the base plate 211, and at the same time, the upper end of the cylinder 214 pulls the driving frame 336 downward, the driving frame 336 moves in the vertical direction under the guidance of the guide sleeve 337, and pushes the compression frame 335 downward, the compression frame 335 moves downward to squeeze the gas in the auxiliary cylinder 334, the gas in the auxiliary cylinder 334 enters the main cylinder 331 through the lower end opening, the gas is compressed after entering the main cylinder 331, and is lifted upward The push rod 332 moves upward to push the push plate 333. The push plate 333 lifts the back cover 5 coated with glue placed on the belt 324 during the movement. The back cover 5 gradually approaches the leather material 6 during the movement. When the leather material 6 is cut, the cut leather material 6 falls on the back cover 5. After the leather material 6 is cut, the cylinder 214 is controlled to reset. At the same time, the upper end of the cylinder 214 cooperates with the driving frame 336 to pull the compression frame 335 upward. The compression frame 335 moves upward and squeezes the gas above the auxiliary cylinder 334. The gas above the cylinder 214 is squeezed into the main cylinder 331. After entering the main cylinder 331, the gas pushes the push rod 332 from top to bottom, so that the push rod 332 pulls the push plate 333 to reset. The push plate 333 drives the back cover 5 with the leather material 6 to reset during the reset. After the reset, the back cover 5 falls back into the groove on the belt 324.

[0074] After the cylinder 214 is completely reset, the motor 2 313 works to drive the shaft 1 314 and the sprocket 2 327. The shaft 1 314 drives the I-shaped wheel 1 315 to rotate under the action of the motor 2 313. The I-shaped wheel 1 315 winds the waste leather material 6 during the rotation process. The waste leather material 6 pulls the uncut leather material 6 during the winding process, so that the subsequent leather material 6 enters the cutting area. When the subsequent leather material 6 enters the cutting area, the sprocket 2 327 is driven by the motor 2 313. The chain 326 meshes with the chain 326 under the action of the sprocket 1 325, and the chain 326 cooperates with the sprocket 1 325 to drive the limit frame 2 323, and the limit frame 2 323 cooperates with the limit frame 1 322 to drive the belt 324 to rotate. During the rotation of the belt 324, the subsequent rear cover 5 is sent to the top of the push plate 333. When the rear cover 5 moves to the top of the push plate 333, the motor 2 313 stops working, and the cylinder 214 works according to the above steps, and the leather material 6 is cut and covered on the rear cover 5 reciprocatingly;

[0075] When the belt 324 moves the back cover 5 covered with the leather material 6 to the area of the upper pressing roller 342, the upper pressing roller 342 cooperates with the lower pressing roller 343 to press the back cover 5 and the leather material 6 passing through, so that the leather material 6 is pressed on the back cover 5;

[0076] While the belt 324 is conveying the rear cover 5, the rear cover 5 will gradually pass under the coater 47. During the process of the rear cover 5 passing under the coater 47, the hose pump 44 is powered on and operates, and cooperates with the connecting flange 42 to pump the glue in the storage tank 41 into the conduit 45. The conduit 45 sends the glue into the coater 47, and the coater 47 coats the glue on the surface of the rear cover 5. The rear cover 5 with the coated glue gradually passes through the squeegee 48, and the squeegee 48 levels the glue on the rear cover 5 in the moving state, so as to realize the glue coating work on the rear cover 5. Then the equipment will run repeatedly according to the above steps to realize the continuous production and processing of the mobile phone leather rear cover 5;

[0077] When it is necessary to replace the leather material 6, rotate the fastening sleeve 318 at one end of the second rotating shaft 317 counterclockwise to remove it. After removing the fastening sleeve 318, take out the second rotating shaft 317. The second rotating shaft 317 loses the restriction on the second spool 319, take out the second spool 319, place the new second spool 319 wound with the leather material 6 in the designated installation area. Then insert the second rotating shaft 317 into the second fixing frame 316 again, and make the second rotating shaft 317 pass through the second spool 319. After the second rotating shaft 317 passes through the other side of the second fixing frame 316, fix the second rotating shaft 317 with the fastening sleeve 318 again. Then pull out the free end of the new leather material 6, and connect the free end of the new leather material 6 and the end of the previous leather material 6 together with tape. After the connection is completed, the previous leather material 6 will pull the new leather material 6 to gradually enter the cutting area. When the cutting part is in the splicing area, the user can manually remove the leather material 6 of the rear cover 5 in the splicing area. When the new leather material 6 appears at the rear end of the equipment and its waste is wound, remove the waste end of the new leather material 6 from the end of the old leather material 6, then remove the left fixing frame one 311. After removing the fixing frame one 311, take down the old spool one 315 from the first rotating shaft 314, then put in a new spool one 315. After the placement is completed, wind the waste end of the new leather material 6 on the new spool one 315, and then complete the replacement operation of the entire leather material 6;

[0078] By setting the cutting device 2, the feeding device 3 and the glue coating device 4, the equipment can integrate multiple processing steps on the same device, thus reducing the problem that when processing the rear cover 5, more equipment is used, resulting in a large occupied space, and during the processing process, it will be interfered by the transfer steps, resulting in a reduction in production efficiency. The three work together, greatly improving the integration degree of the equipment, significantly enhancing the processing efficiency of the mobile phone rear cover 5, saving production space while effectively promoting the high efficiency and intelligence of the production process.

[0079] The electrical components appearing in this article are all connected to the external main controller and 220V mains, and the main controller can be a conventional known device such as a computer for control.
