Description

Technical Field

[0001] This invention relates to an extrusion process for producing collagen sausage casings. Background Technology

[0002] Collagen casings are generally produced through an extrusion process, where an extruder is used to extrude the collagen casing raw material to form a tubular film. However, during the extrusion process, the thickness of the tubular film may not meet the requirements, which necessitates real-time adjustment and control of the tubular film thickness to ensure the product quality of collagen casings. Summary of the Invention

[0003] The purpose of this invention is to provide an extrusion process for producing collagen casings, which uses an extruder to extrude collagen casing raw materials to form a tubular film; a conical tapered section and a conical extrusion head are provided at the output end of the extruder, and the raw material is extruded into a tubular film through the gap between the conical tapered section and the conical extrusion head; the thickness of the tubular film is controlled in real time by adjusting the size of the gap between the conical tapered section and the conical extrusion head; and the conical extrusion head is kept rotating while adjusting the size of the gap between the conical tapered section and the conical extrusion head.

[0004] For details of the present invention, please refer to the embodiments.

[0005] The advantages and beneficial effects of this invention are as follows: It provides an extrusion process for producing collagen casings, which can extrude collagen casing raw materials to form tubular films, and can also adjust and control the thickness of the tubular films in real time, thereby improving the efficiency and effect of raw material extrusion.

[0006] In the raw material extrusion process of this invention, the rotating shaft drives the conical extrusion head to rotate through the connecting block, which can improve the efficiency and effect of raw material extrusion.

[0007] This invention reduces the thickness of the tubular membrane, allowing the connecting block to rotate with the shaft when it moves to the left in the slot, without affecting the rotation of the conical extrusion head with the shaft, thus ensuring the efficiency and effectiveness of raw material extrusion.

[0008] This invention increases the thickness of the tubular membrane, so that when the connecting block moves to the right in the slot, the connecting block can rotate with the rotating shaft without affecting the rotation of the conical extrusion head with the rotating shaft, thus ensuring the efficiency and effect of raw material extrusion.

The structure includes a rotatably connected right bearing 26, a spiral blade 31 located in the cylinder 2 and extending spirally in the left-right direction on the outer circumference of the rotating shaft 3 without extending into the conical tapered section 25, a conical extrusion head 32 located in the conical tapered section 25 and fitted onto the left end of the rotating shaft 3 and slidingly engaged with the rotating shaft 3, and whose outer diameter gradually decreases from right to left, a vertically placed circular turntable 41 fitted onto the right end of the rotating shaft 3, a vertically placed toothed ring 42 fitted onto the outer ring of the turntable 41, a vertically placed gear 43 located below and meshing with the toothed ring 42, and a drive gear 43 that rotates. Motor 44, first column 45 connecting motor 44 to base plate 1, blind hole 33 opened on the right end face of rotating shaft 3 and extending to the left end of rotating shaft 3 in the left-right direction, push-pull rod 5 placed horizontally in the left-right direction and extending into blind hole 33 from the right end of rotating shaft 3 and extending directly below conical extrusion head 32, connecting block 51 connected to the inner ring of conical extrusion head 32 and passing through the side peripheral wall of rotating shaft 3 and extending into blind hole 33, and slot 34 opened on the side peripheral wall of rotating shaft 3 for connecting block 51 to pass through and extending in the left-right direction and slidingly engaging with connecting block 51 (connecting The connecting block 51 can slide left and right in the slot 34; the left bearing 52 is fitted on the left end of the push-pull rod 5 and rotatably connects the connecting block 51 to the rotating shaft 3; the push-pull cylinder 61 is connected to the right end of the push-pull rod 5 and drives the push-pull rod 5 to move left and right; the second column 62 connects the push-pull cylinder 61 to the base plate 1; the rotating shaft 3 is coaxial with the cylinder 2; the conical extrusion head 32 is coaxial with the rotating shaft 3; the blind hole 33 is coaxial with the rotating shaft 3; the push-pull rod 5 is coaxial with the rotating shaft 3; the turntable 41 and the toothed ring 42 are both coaxial with the rotating shaft 3;

[0014] The process of extruding collagen casing raw materials using an extruder to form a tubular film includes the following steps:

[0015] Collagen casing raw material is fed into cylinder 2 through inlet 22; motor 44 drives gear ring 42 to rotate through gear 43, gear ring 42 drives rotating shaft 3 to rotate through turntable 41, rotating shaft 3 drives spiral blade 31 to rotate, spiral blade 31 pushes raw material in cylinder 2 from right to left; raw material is extruded into tubular film through the gap between conical converging section 25 and conical extrusion head 32, and output from outlet 21;

[0016] Furthermore, during the raw material extrusion process, the rotating shaft 3 drives the conical extrusion head 32 to rotate through the connecting block 51, which can improve the efficiency and effect of raw material extrusion.

[0017] The thickness of the tubular membrane is controlled in real time by adjusting the gap between the tapered converging section 25 and the tapered extrusion head 32.

[0018] When it is necessary to reduce the thickness of the tubular membrane, the push-pull cylinder 61 drives the push-pull rod 5 to move to the left. The push-pull rod 5 drives the connecting block 51 to move to the left in the slot 34 through the left bearing 52. The connecting block 51 drives the conical extrusion head 32 to move to the left, thereby reducing the gap between the conical tapered section 25 and the conical extrusion head 32, thus reducing the thickness of the extruded tubular membrane. When the connecting block 51 moves to the left in the slot 34, the connecting block 51 can rotate with the rotating shaft 3 without affecting the rotation of the conical extrusion head 32 with the rotating shaft 3.

[0019] When it is necessary to increase the thickness of the tubular film, the push-pull cylinder 61 drives the push-pull rod 5 to move to the right. The push-pull rod 5 drives the connecting block 51 to move to the right in the slot 34 through the left bearing 52. The connecting block 51 drives the conical extrusion head 32 to move to the right, thereby increasing the gap between the conical tapered section 25 and the conical extrusion head 32, thus increasing the thickness of the extruded tubular film. When the connecting block 51 moves to the right in the slot 34, the connecting block 51 can rotate with the rotating shaft 3, without affecting the rotation of the conical extrusion head 32 with the rotating shaft 3.

[0020] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
