Detailed implementation manners

[0024] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0025] As Figure 1 - Figure 3 shown, an ultrasonic welding device for environmentally friendly paper cups includes: a workbench 1, a forming die 3 is arranged at the middle position of the top of the workbench 1, a blanking mechanism 5 is arranged at one side of the forming die 3, an ultrasonic welding mechanism 2 is arranged above the forming die 3, a clamping displacement assembly is arranged below the forming die 3, and a feeding mechanism 4 is arranged above one end of the workbench 1; bolts are arranged on both sides of the blanking mechanism 5, and the bolts are used to control the clamping width of the blanking mechanism 5.

[0026] Among them, when it is necessary to curl the paper sheet into a paper tube, first the feeding mechanism 4 places the paper sheets on the guide rail at the top of the workbench 1 in sequence. A push rod is arranged inside the guide rail, and the push rod pushes the paper sheet to the position below the forming die 3. Then, by starting the clamping motor 324 inside the moving assembly 320, the clamping assembly 310 clamps the forming die 3, so that the paper sheet below the forming die 3 is curled into a paper tube. Then the ultrasonic welding mechanism 2 moves downward to the overlapping part of the paper tubes, and local heating is generated between the paper sheets through high-frequency sound waves to realize the welding of the paper sheets. Then, the paper sheets welded into paper tubes are taken off by the blanking mechanism 5 and enter the next process.

[0027] Referring to the attached Figure 2 - Figure 4The clamping displacement assembly includes a clamping assembly 310 and a moving assembly 320. There are multiple clamping assemblies 310, and a clamping driving rod 322 is horizontally penetrated inside the multiple clamping assemblies 310. The clamping assembly 310 includes a clamping rotating block 315. Clamping connecting rods 312 are arranged on both sides of the clamping rotating block 315. One end of the clamping connecting rod 312 is fixedly connected to a clamping reel 311. The volumes of the multiple clamping reels 311 decrease successively. The other end of the clamping connecting rod 312 is fixedly connected to a clamping rotating block 315. The intersection of the clamping rotating block 315 and the clamping connecting rod 312 is rotatably connected to the clamping rotating block 315. The clamping rotating block 315 is fixedly connected to a moving wing 313 at a position below the clamping connecting rod 312, and a moving threaded hole 314 is opened inside the moving wing 313.

[0028] According to the above structure, when the molding mold 3 is replaced into the shape required by the paper cup of different shapes, the clamping assembly 310 of different diameter sizes is moved to the position of the corresponding diameter of the molding mold 3, and then the paper sheet under the molding mold 3 is clamped and curled. By moving the clamping driving rod 322 up and down, the clamping rotating block 315 is pressed down, and the clamping connecting rod 312 is used as a lever to make the clamping curling ring 311 clamp the molding mold 3, so that the paper sheet is curled.

[0029] See attached Figure 3 - Figure 5 As shown, the moving assembly 320 includes a driving threaded rod 321 and a clamping driving rod 322. The moving threaded hole 314 is threadedly connected to the driving threaded rod 321. The clamping driving rod 322 is located above the clamping rotating block 315 inside the U-shaped moving frame 316. A return spring 323 is fixedly connected between the two ends of the clamping driving rod 322 and the workbench 1. The workbench 1 is fixedly connected with U-shaped rings at both ends of the clamping driving rod 322. A clamping motor 324 is arranged below the workbench 1 corresponding to the clamping driving rod 322. The driving threaded rod 321 is fixedly connected to a driving motor on one side close to the discharge mechanism 4. The driving threaded rod 321 The number is multiple, and multiple driving threaded rods 321 are arranged in a horizontal array. The ratio between the movable threaded hole 314, the driving threaded rod 321 and the U-shaped movable frame 316 is 2:2:1. The number of driving motors is set to multiple, and each driving motor is transmission-connected to two mutually symmetrical driving threaded rods 321, and the ratio between the driving threaded rods 321 and the driving motors is 2:1; the output end of the clamping motor 324 is fixedly connected to a driving wheel 325, and the driving wheel 325 is horizontally slidably installed through a connecting rod and the lower end of a T-shaped connecting rod 326, and the upper end of the T-shaped connecting rod 326 is fixedly connected to the clamping driving rod 322.

[0030] According to the above structure, when the forming die 3 is replaced with the shape required for different-shaped paper cups and the position of the corresponding clamping component 310 needs to be changed, by starting a corresponding driving motor, it drives two corresponding driving threaded rods 321 to rotate. The moving wings 313 screwed to these two driving threaded rods 321 will drive the corresponding U-shaped moving frame 316 to move linearly, thereby realizing the work of changing the position of a single clamping component 310. By analogy, under the operation of multiple driving motors, the effect of changing the positions of the clamping components 310 can be finally achieved. By starting the clamping motor 324, the driving wheel disc 325 is rotated. Through the rotation of the driving wheel disc 325, the connecting rod makes a circular motion. When the connecting rod makes a circular motion, it moves horizontally and slides horizontally below the T-shaped connecting rod 326, and moves vertically to make the T-shaped connecting rod 326 move up and down, so that the clamping driving rod 322 also moves up and down reciprocally, so that the clamping driving rod 322 contacts the clamping rotating block 315, enabling the clamping coil 311 to clamp the forming die 3.

[0031] The working principle of the present utility model is as follows: when it is necessary to curl the paper sheet into a paper tube, first, the feeding mechanism 4 places the paper sheets on the guide rail on the top of the workbench 1 in sequence. A push rod is arranged inside the guide rail, and the push rod pushes the paper sheet to the position below the forming die 3. Then, by starting the clamping motor 324 inside the moving component 320, the clamping component 310 clamps the forming die 3, so that the paper sheet below the forming die 3 is curled into a paper tube. Then, the ultrasonic welding mechanism 2 moves downward to the overlapping part of the paper tubes, and local heating is generated between the paper sheets through high-frequency sound waves to realize the welding of the paper sheets. Then, the paper sheets welded into a paper tube are taken off by the blanking mechanism 5 and enter the next process.

[0032] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
