Description

Technical Field

[0001] This application relates to the technical field of quick-freezing machinery, in particular to an automatic fish separation device for a quick-freezing machine, which can automatically detect and smoothly separate whole fish from the conveyor belt. Background Art

[0002] In the existing quick-freezing machine technology, the freezing of whole fish is usually carried out by directly placing it on the conveyor belt. The remarkable feature of this method is that the side of the fish body will directly contact the stainless steel wire mesh of the conveyor belt. However, this contact has caused several significant problems in practical applications.

[0003] Firstly, due to the long-term contact between the side of the fish body and the wire mesh of the conveyor belt, obvious wire mesh indentations will be left on the fish body. These indentations not only affect the appearance quality of the product, reducing consumers' desire to purchase, but may also lead to a decrease in the market acceptance of the product.

[0004] Secondly, the large-area contact between the fish body and the conveyor belt increases the risk of adhesion between the two. When the fish product passes through the scraping plate, due to the large resistance caused by adhesion, the fish and the conveyor belt cannot be smoothly separated. This situation will not only cause the product to be stuck and piled up at the outlet, affecting production efficiency, but in severe cases, it may also damage the conveyor belt and the frame structure of the quick-freezing machine, bringing significant economic losses to the enterprise.

[0005] In summary, the existing quick-freezing machine discharging method has obvious deficiencies in the separation of whole fish, and there is an urgent need for a new type of fish separation device to solve the above problems. Utility Model Content

[0006] This application is precisely proposed based on the above needs, aiming to improve the separation efficiency of whole fish from the conveyor belt through automatic detection and separation technology, while reducing the risk of product damage and equipment damage.

[0007] To achieve the above object, this application is implemented through the following technical solutions:

[0008] This application provides an automatic fish separation device for a quick-freezing machine, including an installation unit, a detection unit, a cylinder, a separation push rod, and a control unit.

[0009] As a further improvement of the present application, it further includes an adjustment unit, which is connected between the cylinder and the installation unit and is used to adjust the working angle and position of the separation push rod to adapt to the needs of separating whole fish of different sizes.

[0010] As a further improvement of the present application, it further includes an alarm unit, which is arranged on the discharging mechanism of the quick-freezing machine and is adjacent to the scraping plate of the quick-freezing machine. When the force received by the scraping plate exceeds a preset value, the alarm unit is triggered, and the alarm unit sends an alarm signal to the operator.

[0011] As a further improvement of the present application, it further includes a protection unit, which is arranged on the installation unit and is located outside the separation push rod and is used to protect the separation push rod and prevent the protection personnel from accidentally touching the separation push rod and getting injured.

[0012] As a further improvement of the present application, the surface of the separation push rod is covered with an anti-slip layer to increase the friction when contacting the whole fish and improve the separation efficiency.

[0021] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0022] The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0023] The present application provides an automatic whole fish 8 separation device for a quick-freezing machine, as Figure 1 shown, which includes an installation unit 1, a detection unit 2, a cylinder 3, a separation push rod 4, and a control unit. The installation unit 1 is arranged on the quick-freezing machine discharge mechanism 5 and is located at the end of the conveyor belt 6 for the whole fish 8. The detection unit 2 and the cylinder 3 are both arranged on the installation unit 1 and are respectively electrically connected to the control unit. The detection unit 2 is used to detect the position of the whole fish 8 and send the detection signal to the control unit. The separation push rod 4 is arranged on the cylinder 3 and makes a telescopic movement under the action of the cylinder 3. The control unit controls the movement of the cylinder 3.

[0024] The working principle of the above-mentioned automatic whole fish 8 separation device for the quick-freezing machine is as follows: There is a stainless steel wire mesh tray 7 for fixing the whole fish 8 on the conveyor belt 6. Place the whole fish 8 on the stainless steel wire mesh tray 7. After starting the conveyor belt 6 and the whole fish 8 is frozen, it continues to be transported along with the conveyor belt 6. After the detection unit 2 detects that the whole fish 8 has been transported to the designated position, it converts the signal into an electrical signal and transmits it to the control unit. The control unit controls the cylinder 3 to push the separation push rod 4 to start operating, knocking on the frozen whole fish 8 to separate the whole fish 8 from the fish 8 tray and drop it onto the scraping plate 9, and then slide onto the rear conveyor through the scraping plate 9. After the separation push rod 4 knocks once, it quickly retracts to the original position and repeats the above actions when the next whole fish 8 arrives. Preferably, the detection unit 2 can also detect whether the fish 8 falls off the stainless steel wire mesh tray 7 after being knocked once. If it does not fall off, the whole fish 8 will be knocked a second time, a third time... the Nth time according to the transportation time difference between two adjacent fish 8, where N is a positive integer.

[0025] In an alternative embodiment, it further includes an adjustment unit. The adjustment unit is connected between the cylinder 3 and the installation unit 1 and is used to adjust the working angle and position of the separation push rod 4 to adapt to the separation requirements of whole fish 8 of different sizes.

[0026] In an alternative embodiment, it further includes a speed regulator. The speed regulator is connected between the cylinder 3 and the control unit and is used to adjust the telescopic speed of the cylinder 3 according to the size and quantity of the whole fish 8.

[0027] In an alternative embodiment, the detection unit 2 includes at least one sensor. The sensor is used to detect the position of the whole fish 8 on the conveyor belt 6 in real time and convert the position signal into an electrical signal and send it to the control unit.

[0028] In an alternative embodiment, the control unit includes a programmable logic controller. The programmable logic controller controls the telescopic action of the cylinder 3 according to the received detection signal to achieve automatic control.

[0029] In an alternative embodiment, it further includes an alarm unit 10. The alarm unit 10 is arranged on the discharging mechanism 5 of the quick-freezing machine and is adjacent to the scraping plate 9 of the quick-freezing machine. When the force received by the scraping plate 9 exceeds the preset value, the alarm unit 10 is triggered, and the alarm unit 10 sends an alarm signal to the operator. Because sometimes the frozen fish 8 adheres to the stainless steel wire mesh tray 7 very tightly, and even if the separation push rod 4 knocks many times, the fish 8 cannot fall off the stainless steel wire mesh tray 7. The fish 8 will continue to move forward and contact the scraping plate 9. When the scraping plate 9 receives a large force, the alarm unit 10 will be triggered to send an alarm and stop the machine in time to avoid damaging the conveyor belt 6 and the frame structure of the quick-freezing machine, causing major losses.

[0030] In an alternative embodiment, a protection unit 11 is further included. The protection unit 11 is provided on the mounting unit 1 and is located outside the separation push rod 4, for protecting the separation push rod 4 and preventing the protection personnel from accidentally touching the separation push rod 4 and getting injured.

[0031] In an alternative embodiment, the surface of the separation push rod 4 is covered with an anti-slip layer to increase the friction when contacting the whole fish 8 and improve the separation efficiency. Preferably, the anti-slip layer is a flexible anti-slip layer, for reducing the impact force when separating the whole fish 8 and protecting the whole fish 8 from being damaged.

[0032] In an alternative embodiment, an illumination device is further provided on the mounting rack, for illuminating the end of the whole fish 8 conveyor belt 6 and improving the detection accuracy of the detection device.

[0033] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
