Description

Technical Field

[0001] This utility model relates to the field of tableware manufacturing, and in particular to a rapid prototyping device for disposable tableware. Background Technology

[0002] Disposable tableware refers to tableware designed to be discarded after a single use, including but not limited to plastic knives, forks, spoons, hygienic bamboo chopsticks, paper plates, paper cups, etc. These tableware are widely used in catering services and are popular due to their convenience and low cost. The demand for disposable tableware in the catering industry is huge. In order to improve production efficiency and reduce costs, there is an urgent need in the market for an automated device that can quickly produce disposable tableware.

[0003] There are two main methods for producing disposable tableware: injection molding and vacuum forming. While existing vacuum forming machines can increase the output of disposable tableware, they still have some shortcomings. For example, in terms of the feeding structure, existing equipment often uses simple chutes or conveyor belts for feeding. This method is not only slow, but also prone to problems such as blockage or leakage, requiring manual cleaning afterward. In addition, the positioning accuracy of the tableware during the feeding process is difficult to guarantee, which can easily affect subsequent packaging and transportation.

[0004] Therefore, it is necessary to provide a new rapid prototyping device for disposable tableware to solve the above-mentioned technical problems. Utility Model Content

[0027] Please see Figures 1 to 7A rapid prototyping device for disposable tableware includes: a support 1, a cutting table 2, a cutting plate 3, a pressure rod 5, a pressure roller 4, a feeding structure 6, and a transmission structure 7. The support 1 is fixedly connected to one side of a vacuum forming machine 8. The cutting table 2 is fixedly connected to the side of the support 1 closest to the vacuum forming machine 8. The cutting table has multiple sets of cutting grooves at equal intervals. The cutting plate 3 is slidably connected inside the cutting table 2. The pressure rod 5 is rotatably connected to the top of the cutting plate 3. The pressure roller 4 is rotatably connected to the top of the pressure rod 5.

[0028] It should be noted that the arc-shaped baffle 61 is used to prevent materials from falling when the feeding roller 62 rotates, and the L-shaped column 64 can push the materials out of the feeding roller 62 to prevent material jamming. At the same time, the falling of multiple groups of materials together is more stable and the landing point is more accurate than the falling of a single material.

[0029] Please see Figures 1 to 7The transmission structure 7 includes: a first gear 71, an acceleration gear 72, a first sprocket 73, a chain 74, a second sprocket 75, a third sprocket 76, a reduction gear 77, a second gear 78, a sector gear set 79, a first pulley 80, a second pulley 81, a third pulley 82, and a fourth pulley 83.

A second gear 78 is fixedly connected to one end of the input shaft of the feed roller 62, and the second gear 78 meshes with the sector gear of the sector gear assembly 79 with clearance. A third pulley 82 is installed between the feed roller 62 and the second gear 78, and the shaft center of the third pulley 82 is fixedly connected to the input shaft of the feed roller 62. A fourth pulley is fixedly connected to one end of the input shaft of the feed conveyor belt 65. 83. The third pulley 82 and the fourth pulley 83 are connected by a belt.

[0030] It should be noted that when the pressure rod 5 rises from the bottom to the top, the first gear 71 rotates half a turn, and the sector gear group 79 rotates exactly eighteen degrees. The included angle of the sector gears is eighteen degrees. When the sector gears mesh with the second gear 78, the sector gears rotate eighteen degrees, and the second gear 78 rotates exactly ninety degrees. This is to achieve the rotation of the feed roller 62 by ninety degrees during the tenth rise of the pressure rod 5.

[0031] The working principle of the disposable tableware rapid prototyping device provided by this utility model is as follows:

[0032] Cutting process: Start motor 9, motor 9 drives worm 91 to rotate, worm 91 drives worm wheel to rotate counterclockwise, worm wheel 92 drives pressure wheel 4 to rotate through the input shaft of pressure wheel 4, pressure wheel 4 rotates at the same time, pulling the top of pressure rod 5 to make a circular motion along the axis of pressure wheel 4, and the bottom of pressure rod 5 drives cutting plate 3 to make up-down reciprocating motion, periodically cutting the material in cutting plate 3 into feeding roller 62;

[0033] Material feeding process: The output end of the pressure roller 4 drives the first gear 71 to rotate clockwise. The first gear 71, after speed adjustment by the acceleration gear 72, drives the first sprocket 73 to rotate counterclockwise. The first sprocket 73 drives the second sprocket 75 to rotate counterclockwise via the chain 74. The second sprocket 75 drives the first pulley 80 to rotate counterclockwise. The first pulley 80 drives the second pulley 81 to rotate counterclockwise via the belt. The second pulley 81 drives the waste conveyor belt 66 to rotate counterclockwise via the input shaft of the waste conveyor belt 66. At the same time, the first sprocket 73 drives the third sprocket 76 to rotate counterclockwise via the chain 74. The third sprocket 76, after speed adjustment by the reduction gear 77, drives the large gear of the sector gear set 79 to rotate clockwise. Every time the pressure rod 5 rotates for the tenth time... As the material begins to rise, the push pin 85 on the sector gear in the sector gear assembly 79 contacts the lever 84 of the second gear 78. As the pressure rod 5 rises, the push pin 85 pushes the lever 84 to engage the teeth of the sector gear with the teeth of the second gear 78. When the second gear 78 has just rotated a quarter turn, the pressure rod 5 rises to the top, and the teeth of the sector gear disengage from the second gear 78. During this process, the second gear 78 drives the feeding roller 62 and the third pulley 82 to rotate 90 degrees counterclockwise. The third pulley 82 drives the fourth pulley 83 to rotate 90 degrees counterclockwise via the belt. The fourth pulley 83 drives the feeding conveyor belt 65 to rotate counterclockwise a certain distance through the output end of the feeding conveyor belt 65, carrying the material away from the feeding area.
