DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 A rubber-thread zipper chain element forming device comprises a forming machine base 1 and a turntable 2. The upper surface of the forming machine base 1 is rotatably connected to the turntable 2 through a rotating shaft. A protective mechanism is installed on the upper surface of the forming machine base 1. The protective mechanism comprises a shell 3. The lower surface of the shell 3 is fixedly connected to the upper surface of the forming machine base 1. The turntable 2 is located on the inner side of the shell 3. A feed trough is provided on the side wall surface of the shell 3. A transmission box 31 is fixedly connected to the upper surface of the shell 3. A driving disk 32 is fixedly connected to the upper end of the turntable 2 through a rotating shaft. The driving disk 32 is located on the inner side of the transmission box 31.

[0024] In order to drive the connecting rod 37 to reciprocate, a mounting groove 33 is opened on the upper surface of the driving disk 32. The mounting groove 33 is annular, and the two inner wall surfaces of the mounting groove 33 are provided with latching teeth. The latching teeth on the two inner wall surfaces of the mounting groove 33 are distributed at different positions, so as to avoid the latching teeth on both sides driving the driving gear 36 at the same time. The inner top wall of the transmission box 31 is fixedly connected with a mounting rod 34, and the lower surface of the mounting rod 34 is rotatably connected with a rotating shaft 35. The lower surface of the rotating shaft 35 is fixedly connected with a driving gear 36. The driving gear 36 is located on the inner side of the mounting groove 33. The driving gear 36 is installed on the inner side of the mounting groove 33, so that the driving gear 36 can be driven to rotate by the latching teeth when the driving disk 32 rotates.

[0025] In order to maintain the surface of the turntable 2, a connecting rod 37 is fixedly sleeved on the upper end surface of the rotating shaft 35, and a movable groove is opened on the outer wall surface of the transmission box 31. One end of the connecting rod 37 extends outward through the movable groove, and a telescopic rod 38 is fixedly connected to the lower surface of the outer end of the connecting rod 37. The scraper rod 39 is installed by using the lower end of the telescopic rod 38, so that the scraper rod 39 is driven to rise and fall by the movable end of the telescopic rod 38. The scraper rod 39 is fixedly connected to the lower end side wall surface of the telescopic rod 38, and the outer wall of the housing 3 A positioning groove 310 is provided on the surface, and the positioning groove 310 is inclined. The surface of the scraper rod 39 is slidably connected to the inner wall of the positioning groove 310, and the end of the scraper rod 39 is slidably connected to the outer surface of the turntable 2. A discharge groove 311 is provided on the lower surface of the shell 3, and the discharge groove 311 is located below the positioning groove 310. The scraper rod 39 is composed of a rubber rod body and an end metal scraper, so that it is convenient to pass through the excessively long length of the rubber rod body, thereby keeping the end metal scraper in contact with the surface of the turntable 2 when the connecting rod 37 is deflected.

[0026] By installing a protective mechanism on the surface of the forming machine base 1 and wrapping the surface of the turntable 2 with the outer shell 3 in the protective mechanism, the probability of external impurities adhering to the surface of the turntable 2 is reduced. At the same time, by arranging a scraper rod 39 in the protective mechanism to rub against the outer surface of the turntable 2, while scraping off the impurities on the surface of the turntable 2, the scraper rod 39 is limited by the positioning groove 310, so that the movable scraper rod 39 can move up and down, thereby ensuring the cleaning efficiency of the surface of the turntable 2 while reducing the specifications and surface friction of the scraper rod 39.

[0027] A driving motor 4 is installed inside the molding machine base 1 , and an output shaft of the driving motor 4 is drivingly connected to a rotating shaft on the surface of the rotating disk 2 .

[0028] Working principle:

[0029] When in use, the raw material is inserted into the interior of the housing 3 through the feed trough, and after being processed by the turntable 2, it extends out from the opening at the other end of the feed trough;

[0030] The driving motor 4 drives the driving disc 32 to rotate through the rotating disc 2. When the driving disc 32 rotates, the driving gear 36 is deflected through the latching teeth on one side. The driving gear 36 drives the connecting rod 37 to deflect through the rotating shaft 35. When the driving disc 32 continues to rotate, the latching teeth on the inner side of the mounting groove 33 that contact the surface of the driving gear 36 are switched, the rotation direction of the driving gear 36 changes, and the connecting rod 37 is deflected in the opposite direction, and this action is repeated.

[0031] The connecting rod 37 drives the scraper rod 39 to slide in the positioning groove 310 through the telescopic rod 38. The inner top wall and the inner bottom wall of the positioning groove 310 drive the telescopic rod 38 to contract and extend through the scraper rod 39. At the same time, the end of the scraper rod 39 slides on the outer wall surface of the turntable 2 and scrapes off the impurities on the surface of the turntable 2. The rotating turntable 2 sweeps out the scraped impurities through the discharge trough 311.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
