Description

Technical Field

[0001] The utility model discloses an extrusion device for cod fish sausage, belonging to the technical field of food processing equipment. Background Art

[0002] Cod fish sausage is a kind of food made mainly of cod fish meat. It is popular among parents and children because of its high nutritional value and good taste. When making cod fish sausage, raw materials such as cod fish, egg white, and starch are stirred to make fish paste, and then the fish paste is filled into a sausage casing by applying pressure in a fish paste extrusion device, and finally the cod fish sausage can be obtained through steaming.

[0003] At present, for the existing extrusion device for cod fish sausage, when the fish paste is extruded under pressure into the sausage casing, the sausage casing is very easy to fall off from the discharge pipe of the fish paste extrusion device, resulting in inconvenient use and affecting the production efficiency of cod fish sausage.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide an extrusion device for cod fish sausage to solve the above problems, which has the effect of preventing the sausage casing from falling off during filling.

[0006] The utility model realizes the above purpose through the following technical solutions. It includes a discharge pipe, and a fixed sleeve that can move axially along the discharge pipe is arranged on the outer side of the discharge pipe. A connecting sleeve is arranged at the front end of the discharge pipe, and the outer diameter of the connecting sleeve is smaller than that of the discharge pipe. When the fixed sleeve moves towards the front end of the discharge pipe until the front end of the fixed sleeve extends to the front end of the connecting sleeve, a fixing cavity for sleeving the sausage casing is formed between the inner side of the fixed sleeve and the outer side of the connecting sleeve. A conical sleeve is arranged at the front end of the connecting sleeve. The larger end of the conical sleeve is connected to the connecting sleeve. Ring-shaped protrusions are arranged on the outer side of the larger end of the conical sleeve and the inner side of the front end of the fixed sleeve. An intestinal outlet channel for the sausage casing to pass through is formed by the ring-shaped protrusions on the conical sleeve and the fixed sleeve, and the width of the intestinal outlet channel is smaller than the width of the fixing cavity.

[0007] By adopting the above technical solution, the rear end of the discharge pipe is connected to the extruder. When using the casing to fill the fish paste, the open end of the casing is sleeved on the connecting sleeve, and the fixing sleeve is moved forward to form a fixing cavity for accommodating the casing between the fixing sleeve and the connecting sleeve, so that the casing can be fixed, and the fish paste extruded from the discharge pipe can stably enter the casing to complete the filling. The conical sleeve is provided to stably guide the fish paste into the casing. The front end of the conical sleeve is the end with a smaller barrel opening, so that the amount of fish paste during filling into the casing increases from small to large, avoiding bursting the casing due to a large amount of fish paste filled at one time, effectively improving the stability of filling. Through the arrangement of two annular protrusions, when the casing gradually moves outward during the filling process, the sausage outlet channel formed by the two annular protrusions can limit the passing rate of the casing, enabling the casing to pass through only in a single layer to avoid the overall shedding of the casing during filling. At the same time, it can smooth the surface of the casing to avoid the phenomenon of casing stacking during filling.

[0008] Preferably, a plurality of anti-slip protrusions are evenly arranged on the outer wall of the connecting sleeve along the circumferential direction of the connecting sleeve.

[0009] By adopting the above technical solution, through the arrangement of a plurality of anti-slip protrusions, the friction between the casing and the connecting sleeve is increased, further preventing the casing from sliding or falling off during the production process.

[0010] Preferably, the inner diameter of the discharge pipe, the inner diameter of the connecting sleeve, and the inner diameter of the larger end of the barrel opening of the conical sleeve are all the same, and the inner diameter of the smaller end of the barrel opening of the conical sleeve is smaller than the inner diameter of the discharge pipe.

[0011] By adopting the above technical solution, the same inner diameter design of the discharge pipe, the connecting sleeve, and the conical sleeve simplifies the equipment structure and makes the material filling and extrusion process smoother. The design that the inner diameter of the smaller end of the barrel opening of the conical sleeve is smaller than the inner diameter of the discharge pipe can avoid bursting the casing due to a sudden extrusion of a large amount of fish paste, making the filling of the fish paste more stable.

[0012] Preferably, an external thread is provided on the outer side of the front end of the discharge pipe, and a first internal thread for connecting with the external thread on the outer side of the front end of the discharge pipe is provided on the inner side of the rear end of the fixing sleeve.

[0013] By adopting the above technical solution, through the arrangement of the external thread and the first internal thread, the movement of the fixing sleeve is more accurate and stable, improving the fixing effect of the fixing sleeve on the casing.

[0014] Preferably, a second internal thread is provided on the inner side of the rear end of the discharge pipe.

[0015] By adopting the above technical solution, the second internal thread is used to connect the discharge pipe to the extruder, making the disassembly and installation of the discharge pipe more convenient and facilitating the cleaning and maintenance of the discharge pipe.

[0016] Preferably, an arc chamfer is provided on the outer side of the smaller end of the conical sleeve opening.

[0017] By adopting the above technical solution, the design of the arc chamfer can reduce the friction between the casing and the conical sleeve, avoid the breakage of the casing during filling, and improve the yield rate of product production.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] First, by providing a movable fixing sleeve on the outer side of the discharge pipe and a connecting sleeve at the front end of the discharge pipe, when the fixing sleeve moves towards the front end of the discharge pipe, a fixing cavity for sleeving the casing is formed between the fixing sleeve and the connecting sleeve. This design enables the casing to be firmly sleeved on the device, not easy to slip or move, thus improving the stability and efficiency of the production process.

[0020] Second, the conical sleeve provided at the front end of the connecting sleeve and the sausage outlet channel formed by the annular protrusions on the conical sleeve and the fixing sleeve make the casing more smooth during the filling process. At the same time, the width of the sausage outlet channel is smaller than the width of the fixing cavity, which can limit the passing rate of the casing and further prevent the casing from falling off during filling.

[0021] Third, the anti-slip protrusion design on the outer wall of the connecting sleeve increases the friction between the connecting sleeve and the casing, further fixes and restricts the casing, and improves the yield rate and stability of filling.

[0022] Fourth, the external thread provided on the outer side of the front end of the discharge pipe, the first internal thread on the inner side of the rear end of the fixing sleeve, and the second internal thread on the inner side of the rear end of the discharge pipe make the connection and disassembly of the device more convenient and fast, which helps to improve the production efficiency and maintenance convenience.

In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] An extrusion device for cod fish sausage, as Figures 1 - 3 shown, includes a discharge pipe 1. A fixed sleeve 2 that can move axially along the discharge pipe 1 is arranged outside the discharge pipe 1. A connecting sleeve 3 is arranged at the front end of the discharge pipe 1. The outer diameter of the connecting sleeve 3 is smaller than the outer diameter of the discharge pipe 1. When the fixed sleeve 2 moves forward to the front end of the discharge pipe 1 and the front end of the fixed sleeve 2 extends to the front end of the connecting sleeve 3, a fixing cavity 4 for sleeving the casing is formed between the inner side of the fixed sleeve 2 and the outer side of the connecting sleeve 3. The rear end of the discharge pipe 1 is connected to an extruder. When the casing is to be used to fill fish paste, the open end of the casing is sleeved on the connecting sleeve 3, and the fixed sleeve 2 is moved forward so that the fixed sleeve 2 and the connecting sleeve 3 form a fixing cavity 4 for accommodating the casing, thereby the casing can be fixed, and the fish paste extruded from the discharge pipe 1 can stably enter the casing to complete the filling. A conical sleeve 5 is arranged at the front end of the connecting sleeve 3. The larger end of the conical sleeve 5 is connected to the connecting sleeve 3. Annular protrusions 6 are arranged on the outer side of the larger end of the conical sleeve 5 and the inner side of the front end of the fixed sleeve 2. The annular protrusions 6 on the conical sleeve 5 and the fixed sleeve 2 form an intestinal passage 7 for the casing to pass through. The width of the intestinal passage 7 is smaller than the width of the fixing cavity 4. The setting of the conical sleeve 5 can stably guide the fish paste into the casing, and the front end of the conical sleeve 5 is the smaller end, so that the amount of fish paste when filling the casing increases from small to large, avoiding the casing being burst by a large amount of fish paste filled at one time, effectively improving the stability of filling. Through the setting of the two annular protrusions 6, when the casing gradually moves outwards during the filling process, the intestinal passage 7 formed by the two annular protrusions 6 can limit the passing rate of the casing, so that the casing can only pass through in a single layer to avoid the whole casing falling off during filling, and at the same time, the surface of the casing can be smoothed to avoid the phenomenon of the casing being stacked during filling.

[0029] A number of anti-slip protrusions 8 are evenly arranged on the outer wall of the connecting sleeve 3 along the circumferential direction of the connecting sleeve 3. Through the arrangement of the number of anti-slip protrusions 8, the friction between the casing and the connecting sleeve 3 is increased, further preventing the casing from sliding or falling off during the production process, ensuring the stability of product production. The inner diameters of the discharge pipe 1, the connecting sleeve 3, and the larger end of the opening of the conical sleeve 5 are all the same. The inner diameter of the smaller end of the conical sleeve 5 is smaller than the inner diameter of the discharge pipe 1. The same inner diameter design of the discharge pipe 1, the connecting sleeve 3, and the conical sleeve 5 simplifies the equipment structure and makes the material filling and extrusion process smoother. The design that the inner diameter of the smaller end of the conical sleeve 5 is smaller than the inner diameter of the discharge pipe 1 can prevent a large amount of fish paste from suddenly squeezing out and bursting the casing, making the filling of the fish paste more stable.

[0030] External threads are provided on the outer side of the front end of the discharge pipe 1, and a first internal thread for connecting with the external threads on the outer side of the front end of the discharge pipe 1 is provided on the inner side of the rear end of the fixing sleeve 2. Through the arrangement of the external threads and the first internal thread, the movement of the fixing sleeve 2 is more accurate and stable, improving the fixing effect of the fixing sleeve 2 on the casing. A second internal thread is provided on the inner side of the rear end of the discharge pipe 1, and the second internal thread is used to connect the discharge pipe 1 to the extruder, making the disassembly and installation of the discharge pipe 1 more convenient and facilitating the cleaning and maintenance of the discharge pipe 1. An arc-shaped chamfer is provided on the outer side of the smaller end of the conical sleeve 5. The design of the arc-shaped chamfer can reduce the friction between the casing and the conical sleeve 5, avoid the casing from being damaged during filling, and improve the yield rate of product production.

[0031] When filling the cod sausage, the discharge pipe 1 is connected to the extruder filled with fish paste through the second internal thread, and then the fixing sleeve 2 is rotated backward to expose the connecting sleeve 3. The casing is passed through the conical sleeve 5 from the opening and sleeved on the connecting sleeve 3, and then the fixing sleeve 2 is rotated forward to form a fixing cavity 4 for fixing the casing between the fixing sleeve 2 and the connecting sleeve 3. Furthermore, the extending effect of the casing during filling is restricted through the fixing cavity 4 and the sausage outlet channel 7, so as to avoid the casing from falling off and improve the filling effect and filling stability of the cod sausage filling.
