[0029] In a typical implementation of the present invention, Figure 1 As shown, a kneading machine discharging spiral end structure is proposed, which is installed at the discharging end of the kneading machine to support the kneading machine spiral end and scrape the material at the discharging port.
[0030] The discharge spiral terminal structure comprises an end plate 2 fixedly connected to the end of a discharge barrel 1 . A screw rod 3 is arranged in the discharge barrel 1 , and the end of the screw rod 3 is connected to the end plate 2 .
[0031] Among them, the end plate 2 is arranged radially along the discharge barrel 1, a through hole is opened in the middle of the end plate 2 for the screw 3 to pass through, and a fully enclosed bearing 4 is arranged between the screw 3 and the end plate 2. The end plate 2 is also fixedly connected to the cover plate 5, and the cover plate seals the fully enclosed bearing 4 therein.
[0032] Specifically, bolt holes are provided on the outer circumference of the end plate 2, and the end plate 2 and the end of the discharge barrel 1 are fixedly connected by inserting bolts or other connecting parts into the bolt holes; threaded holes are provided on the inner circumference of the end plate 2, and the end plate 2 and the cover plate 5 are fixedly connected by inserting screws or other connecting parts into the threaded holes.
[0033] The cover plate 5 and the end plate 2 are arranged in parallel. A top block can be arranged inside the cover plate 5 to press against the end of the fully enclosed bearing 4 to limit the axial position of the fully enclosed bearing 4 .
[0034] In order to prevent the material from being squeezed into the bearing when conveying in the discharging barrel 1 of the kneading machine, a skeleton oil seal 6 is provided at the contact point between the outer periphery of the screw 3 and the end plate 2, and the skeleton oil seal 6 is provided inside the fully enclosed bearing 4, that is, the fully enclosed bearing 4 is closer to the end of the screw 3 than the skeleton oil seal 6. During operation, the skeleton oil seal can prevent collagen from being squeezed into the bearing.
[0035] Among them, spiral blades 7 are arranged on the periphery of the screw 3, and the rotation of the spiral blades can drive materials such as collagen to move and transport them; a first baffle 8 is fixedly arranged on the periphery of the screw 3 near the end, and the first baffle 8 is located at the junction of the screw 3 and the end plate 2. The first baffle can block the collagen. Through the cooperation of the first baffle and the skeleton oil seal, it can play a dual protection role for the fully enclosed bearing, extend its service life, and correspondingly reduce the maintenance frequency and maintenance cost.
[0036] A discharge port 9 is provided at the bottom of the end of the discharge barrel 1, and materials such as collagen are driven by the spiral blades of the screw to move to the discharge port for discharge.
[0037] In a preferred embodiment, a second baffle 10 is fixedly arranged on the periphery of the screw 3, and there is a certain interval between the second baffle 10 and the first baffle 8, and spiral blades are no longer arranged on the periphery of the screw between the first baffle and the second baffle; the first baffle and the second baffle are both arranged along the radial direction of the screw, and their peripheries are arranged adjacent to the inner wall of the discharge barrel.
[0038] The first baffle 8 is closer to the end of the screw 3 than the second baffle 10 , and the discharge port 9 is located below the second baffle 10 .
[0039] In a further solution, a scraper plate 11 is fixedly provided at the discharge port 9 , and the scraper plate 11 is extended from the discharge port 9 to the inside of the discharge barrel 1 .
[0040] The scraper plate 11 is radially arranged along the discharge barrel 1 and extends to the periphery of the screw 3. The scraper plate 11 scrapes the collagen before the first baffle during the collagen conveying process, and can also prevent the collagen from being squeezed into the bearing.
[0041] Specifically, the first end of the scraper plate 11 is fixed to the side wall of the discharge port 9 of the discharge barrel 1, and the second end of the scraper plate 11 extends radially along the discharge barrel 1 toward the inside of the discharge barrel 1 to the outer periphery of the screw 3; the second end of the scraper plate 11 is set as a right-angled triangle structure, one right-angled side of the right-angled triangle structure is parallel to the axial direction of the screw, and the other right-angled side of the right-angled triangle structure is parallel to the radial direction of the screw, and the hypotenuse of the right-angled triangle structure forms an angled area with the first end of the scraper plate, and one side of the right-angled triangle structure is set away from the end of the screw; during the rotation of the screw, the collagen reaching the scraper plate is scraped off by the corner of the second end of the scraper plate 11, and then moves downward through the hypotenuse of the right-angled triangle structure, and is collected and stored after being discharged from the discharge port.
[0042] Furthermore, the scraper plate 11 is placed between the first baffle plate 8 and the second baffle plate 10, and the corner of the second end of the scraper plate 11 is set toward the second baffle plate, and there is a gap between the second baffle plate; thus, the second baffle plate can form a first line of defense to prevent collagen from squeezing into the end of the discharge barrel, the scraper plate can form a second line of defense to prevent collagen from squeezing into the end of the discharge barrel, the first baffle plate can form a third line of defense to prevent collagen from squeezing into the end of the discharge barrel, and the skeleton oil seal can further prevent collagen from squeezing into the bearing.
[0043] Since the discharge port 9 is arranged below the second baffle 10, the discharge port 9 has space on both sides corresponding to the second baffle 10, and two discharge areas are formed on both sides of the second baffle 10: an abnormal discharge area is formed between the second baffle 10 and the scraper plate 11, and a normal discharge area is formed on the other side of the second baffle 10, and the normal discharge area is located on the side of the second baffle 10 away from the end of the screw. Since the quality of collagen has decreased after being squeezed into the area between the second baffle and the scraper plate through the gap, it is discharged from the abnormal discharge area and stored as an abnormal material, while the quality of the collagen that has not been squeezed in is higher, and it is discharged from the normal discharge area and stored, so that the abnormal material and the normal collagen material will not be mixed, thereby reducing the contamination of the normal collagen material.
[0044] In another typical embodiment of the present invention, a kneading machine is provided, comprising the above-mentioned discharge spiral terminal structure.
[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
