Description

Technical Field

[0001] This utility model relates to the field of meat product sorting, and in particular to an automated sorting machine for frozen meat products. Background Technology

[0002] Frozen meat products are foods made from livestock, poultry, or aquatic products through rapid low-temperature freezing. They are mainly divided into two categories: frozen fresh meat and frozen prepared meat products. Frozen fresh meat requires pre-cooling and acid removal processes to inhibit microbial growth and extend its shelf life to several months, but it requires a complete cold chain to maintain its quality. Frozen prepared meat products (such as meatballs and ready-to-cook dishes) achieve ready-to-eat characteristics through standardized processing, offering significant advantages in food convenience and safety. With the expansion of industrial production scale, these products require standardized packaging after freezing, and the weight sorting process before packaging is particularly important for ensuring product compliance.

[0003] Existing sorting technologies mainly use weighing devices to detect the weight of frozen meat products and mechanical sorting mechanisms to remove products that do not meet the weight requirements to the manual processing area. However, sorting machines can only perform simple weight grading and can only physically isolate products that are underweight without making up for their weight. This results in defective products needing to be reprocessed manually a second time, which reduces the efficiency of the production line. Furthermore, frequent manual intervention can easily lead to hygiene risks and makes it difficult to meet the standards of modern food industry for automated and precise production.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automated sorting machine for frozen meat products to solve the aforementioned technical defects.

The conveyor frame two is symmetrically provided with rotatably connected rollers two inside, and a conveyor belt two is sleeved on the outside of the rollers two.

[0009] Preferably, the conveyor frame three has symmetrically arranged roller three and roller four rotatably connected inside. A conveyor belt three is sleeved on the outside of roller three and a conveyor belt four is sleeved on the outside of roller four. Roller three and roller four are fixedly connected by a coupling. Roller three and roller two are driven by a synchronous pulley assembly. The synchronous pulley assembly consists of two synchronous pulleys and a synchronous belt, and the synchronous belt is sleeved on the outside of the synchronous pulleys for transmission.

[0010] Preferably, an arc-shaped support plate is placed above the electronic scale, and a servo motor is fixedly installed on one side of the L-plate by bolts. An extension shaft is fixedly installed on the drive shaft of the servo motor, and a pusher plate is fixedly installed on the outer side of the extension shaft.

[0011] Preferably, the drive shaft of the second stepper motor is fixedly provided with a partition plate, a placement groove is placed on one side of the third conveyor frame, an electric push rod is fixedly provided at one end of the placement groove by bolts, and a push plate is fixedly provided at the end of the drive shaft of the electric push rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses multi-stage conveyor belts to sequentially transport frozen meat products to the weighing station, where electronic scales perform real-time weighing and detection. When the product weight is within acceptable limits, it is guided to the qualified product conveyor belt by a separator and a pushing mechanism. If the weight is insufficient, a reverse sorting mechanism is activated to guide the product into the replenishment channel, while a precise cutting device automatically adds a fixed amount of meat strips. This enables the replenishment of unqualified products, effectively solving the problems of low rework efficiency and frequent manual intervention in traditional sorting technology, thereby improving the continuous operation capability of the production line.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1 - Figure 5 As shown, this utility model is an automated sorting machine for frozen meat products, including a conveyor frame 1. A stepper motor 11 is fixedly installed on one side of the conveyor frame 1 by bolts. The conveyor frame 1 also has symmetrically rotatably connected rollers 1 inside. The drive shaft of the stepper motor 11 is fixedly connected to the shaft of one of the rollers 1. A conveyor belt 12 is sleeved on the outside of the roller 1. A conveyor frame 2 13 is placed at one end of the conveyor frame 1. A conveyor frame 3 15 is placed at one end of the conveyor frame 2. A roller 2 is symmetrically rotatably connected inside the conveyor frame 2. A conveyor belt 2 14 is sleeved on the outside of the roller 2. The roller 1 and roller 2 are driven by a synchronous pulley assembly 18.

[0025] The synchronous pulley assembly 18 consists of two synchronous pulleys and a synchronous belt. The synchronous belt is sleeved on the outside of the synchronous pulleys for transmission. Inside the conveyor frame 3 15, there are symmetrically arranged rollers 3 and 4 that are rotatably connected. The outside of roller 3 is sleeved with conveyor belt 3 16, and the outside of roller 4 is sleeved with conveyor belt 4 17. Roller 3 and roller 4 are fixedly connected by a coupling. Roller 3 and roller 2 are driven by the synchronous pulley assembly 18. A mounting frame 19 is also fixedly installed on the top of the conveyor frame 2 13 by bolts.

[0026] An L-plate 20 is placed between conveyor frame 1 and conveyor frame 2 13. An electronic scale 21 is fixedly installed on the top of the L-plate 20 by bolts. An arc-shaped support plate 22 is placed on the top of the electronic scale 21. A servo motor 23 is also fixedly installed on one side of the L-plate 20 by bolts. An extension shaft 24 is fixedly installed on the drive shaft of the servo motor 23. A pusher plate 25 is fixedly installed on the outside of the extension shaft 24. When the servo motor 23 starts, it drives the extension shaft 24 to rotate. The extension shaft 24 drives the pusher plate 25 to make a circular motion, thereby pushing the weighed frozen meat products on the arc-shaped support plate 22 to the top of the conveyor belt 2 14.

[0027] A stepper motor 26 is bolted to the top of the mounting frame 19. A partition plate 27 is fixed to the drive shaft of the stepper motor 26. A placement slot 28 is placed on one side of the conveyor frame 3 15. An electric push rod 29 is bolted to one end of the placement slot 28. A push plate 30 is fixed to the end of the drive shaft of the electric push rod 29. A fixedly connected gate frame 31 is provided above the other end of the placement slot 28. An electric push rod 32 is bolted to the top of the gate frame 31. A cutter 33 is fixed after the drive shaft of the electric push rod 32 passes through the gate frame 31. Frozen meat strips are placed in the placement slot 28.

[0028] The working process and principle of this utility model are as follows:

[0029] In use, the frozen meat products are first conveyed to the top of conveyor belt 12 via the conveyor. Then, stepper motor 11 is started. Stepper motor 11 drives conveyor belt 12, conveyor belt 24, conveyor belt 316 and conveyor belt 417 to run synchronously through synchronous pulley assembly 18 for conveying operation. Conveyor belt 12 conveys the frozen meat products to the top of the arc-shaped support plate 22. At this time, electronic scale 21 weighs the frozen meat products. If the weight of the frozen meat products is qualified, stepper motor 26 is started to drive the partition plate 27 to rotate clockwise until one end of the partition plate 27 contacts the inner wall of conveyor frame 23.

[0030] At this point, the servo motor 23 is started to drive the extension shaft 24 and the pusher plate 25 to rotate, thereby pushing the weighed frozen meat products on the arc support plate 22 to the top of the second conveyor belt 14. Then, the qualified frozen meat products are guided by the second conveyor belt 14 and the separator plate 27 to the top of the third conveyor belt 16. If the weight of the frozen meat products is lower than the preset value, the stepper motor 26 is started to drive the separator plate 27 to rotate counterclockwise, thereby conveying the frozen meat products into the fourth conveyor belt 17. At the same time, the electric push rod 29 is started, and the electric push rod 29 drives the push plate 30 to convey the frozen meat strips in the placement groove 28 to the cutter 33. Then, the electric push rod 32 is started to drive the cutter 33 to press down, thereby cutting out meat strips of appropriate weight. The cut meat strips fall into the top of the fourth conveyor belt 17, thereby making up for the weight of the frozen meat products that are underweight on the fourth conveyor belt 17.
