Description

Technical Field

[0001] This utility model relates to a mechanism for processing long and narrow fish products, belonging to the field of aquatic product processing machinery technology. Background Technology

[0002] Long, slender fish, such as eels and loaches, are cumbersome to kill manually, requiring multiple steps including gutting, removing internal organs, and deboning. With the development of aquaculture, loaches and eels have entered factory farming, leading to a surge in the market for processed, ready-to-eat eel and loach products. Manual killing and deboning of eels and loaches clearly cannot meet the demands of factory farming and processing. However, due to their elongated shape, long, slender fish tend to curl up during the gutting process, making subsequent gutting difficult. Therefore, there is an urgent need for an automated mechanism that can straighten and compress long, slender fish products to automate the killing process. Summary of the Invention

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figure 1 , 2The device shown is a long strip fish straightening and pressing device, including a base 13, a long strip fish product processing mechanism 10 mounted on the base 13, a motor cover 14 mounted on the long strip fish product processing mechanism to protect the motor, a baffle 11 covering and protecting the long strip fish product processing mechanism, and a feeding hopper 12 mounted on the baffle 11. The feeding hopper 12 is used to insert fish into the mechanism from the inlet end of the long strip fish product processing mechanism 10 after the fish is put in.

[0031] Figure 3 A rough exploded view of the elongated fish product processing mechanism 10 is shown in the figure. The mechanism 10 comprises a core assembly 101 and a power assembly 102. The power assembly 102 is equipped with a motor 102-1 and a gearbox 102-3. A motor pulley 102-1-1 is mounted on the output shaft of the motor 102-1. A synchronous belt 102-2 connects the motor to the input pulley 102-3-1 in the gearbox 102-3, forming a synchronous power connection. This connection method can also be a chain connection, gear connection, flexible shaft, or other mechanical transmission methods. The purpose is to allow the motor to output power to the internal mechanical transmission mechanism of the gearbox, which is the basic concept of this invention. The gearbox 102-3 contains multiple gear transmission sets for power output to necessary components. These include gear 102-3-2, which meshes with the main pulley shaft 101-1 on the movement assembly 101; the main pulley shaft 101-1 is connected to the main pulley pulley 101-5 via a transmission mechanism, driving the left synchronous belt 101-7 to rotate; gear 102-3-3, which meshes with the small blade shaft 101-2 on the movement assembly 101; gear 102-3-4, which meshes with the first blade component 101-3 on the movement assembly 101 via the blade component output shaft 102-3-5; and gear 102-3-6, which meshes with the back pressure wheel shaft 101-30-4 on the movement assembly 101. The transmission mechanism within the gearbox can be a gear engagement, or it can be a flexible wheel that transmits power through surface friction, or it can be a chain and sprocket engagement, or a synchronous belt and synchronous belt pulley engagement, or it can use a combination of couplings such as flexible shafts to achieve power transmission. All of these methods can achieve the purpose of the mechanism transmitting power.

[0032] Figure 4The structure of the movement assembly 101, viewed from the bottom, is further illustrated. The main pulley shaft 101-1 transmits power to the main pulley shaft 101-1-3 via two cooperating gears 101-1-1 and 101-1-2. The main pulley 101-5 is mounted on the main pulley shaft 101-1-3. Simultaneously, the main pulley shaft 101-1 transmits power to the main pulley shaft 101-1-6 via two cooperating gears 101-1-4 and 101-1-5. The knife shaft 101-2 outputs power to the small blade 101-2-1. The first cutting tool component 101-3 and the second cutting tool component 101-4 are symmetrically mounted. The output gear 101-3-1 on the first cutting tool component 101-3 is mated with the output gear 101-4-1 on the second cutting tool component 101-4. Power is transmitted to the output gear 101-4-1 through the output gear 101-3-1, thereby completing the synchronous rotation of the shaft system on the two cutting tool components. In addition to the gear drive described above, the power transmission between the two cutting tool components can also be achieved through other connection methods such as couplings.

[0033] Figure 5A partial schematic diagram of the movement assembly 101 is shown, which includes a left synchronizer frame assembly 101-11 and a right synchronizer frame assembly 101-18. The left synchronizer frame assembly 101-11 includes a left synchronizer frame 101-11-1 and a left driven pulley 101-6 mounted on the left synchronizer frame 101-11-1. The proximal end of the left synchronizer frame 101-11-1 includes a left synchronizer frame shaft 101-10, and the left synchronizer frame assembly 101-11 can rotate along the left synchronizer frame shaft 101-10, thereby driving the left synchronizer belt 101-7 mounted on the left driven pulley 101-6 to rotate together. The distal end of the left synchronizer frame 101-11-1 includes a left sliding shaft 101-11-2. Similarly, the right synchronous pulley frame assembly 101-18 includes a right synchronous pulley frame 101-18-1 and a right driven pulley 101-13 mounted on the right synchronous pulley frame 101-18-1. The proximal end of the right synchronous pulley frame 101-18-1 includes a right synchronous pulley frame shaft 101-17. The right synchronous pulley frame assembly 101-18 can rotate along the right synchronous pulley frame shaft 101-17, thereby driving the right synchronous belt 101-14 mounted on the right driven pulley 101-13 to rotate together. The distal end of the right synchronous pulley frame 101-18-1 includes a right sliding shaft 101-18-2. A left clamping wheel cantilever 101-8, capable of rotating along the axis of the left synchronous pulley frame shaft 101-10, is mounted on the left synchronous pulley frame shaft 101-10. A left clamping wheel shaft 101-8-1 is mounted on the other end of the left clamping wheel cantilever 101-8-1, and the left clamping wheel 101-9 is mounted on the left clamping wheel shaft 101-8-1. Similarly, a right clamping wheel cantilever 101-15, capable of rotating along the axis of the right synchronous pulley frame shaft 101-17, is mounted on the right synchronous pulley frame shaft 101-17. A right clamping wheel shaft 101-15-1 is mounted on the other end of the right clamping wheel cantilever 101-15-1, and the right clamping wheel 101-16 is mounted on the right clamping wheel shaft 101-15-1. A spring 101-20 is installed and connected between the left synchronous pulley frame assembly 10-11 and the right synchronous pulley frame assembly 10-18, elastically connecting the two synchronous pulley frame assemblies 10-11 and 10-18. The inner sides of the left synchronous belt 101-7 and the right synchronous belt 101-14 form a clamping channel. Fish products are clamped within this channel by the belts on both sides, and under power, the fish products are clamped and transferred from the inlet end to the outlet end. The left pressure roller 101-9 includes an inner cylindrical surface and an outer cylindrical surface. The outer cylindrical surface can rotate circumferentially along the left pressure roller shaft 101-8-1. The right pressure roller 101-16 also includes an inner cylindrical surface and an outer cylindrical surface. The outer cylindrical surface can rotate circumferentially along the right pressure roller shaft 101-15-1.The left or right clamping wheel includes a bearing or a nylon wheel, which ensures that during the elastic compression process, the outer cylindrical surface of the clamping wheel undergoes relative rolling friction with the corresponding left or right timing belt, rather than sliding friction, reducing wear between the timing belt and the clamping wheel and extending its service life.

[0034] Furthermore, Figure 5 and Figure 6 The enlarged view shows that the clamping channel entrance includes a left clamping roller 101-9 and a right clamping roller 101-16. The clamping rollers on both sides have symmetrical and identical structures. Taking the left clamping roller 101-9 as an example, it is mounted on one end of a left clamping roller cantilever 101-8. The other end of the left clamping roller cantilever 101-8 has a rotating mounting hole, which is used to install it with the left clamping roller cantilever shaft 101-10, allowing it to rotate around the left clamping roller cantilever shaft 101-10. Similarly, the right clamping roller 101-16 on the right side also has similar components such as a right clamping roller cantilever 101-15 and a right clamping roller cantilever shaft 101-17. The two clamping rollers are elastically connected by a spring 101-19. The left and right clamping rollers, under the force of springs 101-19, elastically compress the left synchronous belt 101-7 and the right synchronous belt 101-14 respectively in the direction of the clamping channel between them, giving the synchronous belts an elastic compressive force in the direction of the clamping channel. The springs 101-19 can also be replaced by elastic rubber cables.

[0035] like Figure 7 As shown, one optional technical solution includes a left clamping plate 101-24 and a spring 101-23 at the inlet end. The spring 101-23 presses against the left clamping plate 101-24, further adhering to the left synchronous belt 101-7 and continuously applying elastic compressive force to the left synchronous belt 101-7 towards the central clamping channel. Similarly, the inlet end also includes a right clamping plate 101-22 and a spring 101-21. The spring 101-21 presses against the right clamping plate 101-22, further adhering to the right synchronous belt 101-14 and continuously applying elastic compressive force to the right synchronous belt 101-14 towards the central clamping channel. This figure illustrates the effect of elastic compression achieved through the combined action of the springs 101-21. The left clamping plate 101-24 or the right clamping plate 101-22 can also be made of elastically recoverable materials, such as spring steel sheets or elastic non-metallic materials, thus reducing the use of springs.

[0036] Furthermore, the outer surfaces of the left synchronous belt 101-7 and the right synchronous belt 101-14 have anti-slip textures, including toothed or mesh patterns. Synchronous belts with anti-slip textures can more stably grip the fish's body and transfer it forward through the gripping channel.

[0037] like Figure 8 As shown, when the long strip fish 16 enters the clamping channel under the combined force of the left and right synchronous belts, it is transmitted forward. Under the front and rear force of the pressure wheel and pressure plate, the body of the fish 16 is straightened and pressed against the belt.

[0038] Based on the above structure, when fish of different sizes enter the clamping channel, they pass through the left and right clamping rollers and left and right clamping plates at the entrance, and the left and right synchronous belts and the fish's body automatically and elastically fit together, thus straightening the fish's body.

[0039] This application is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
