Description

Technical Field

[0001] This invention relates to a conveyor line, and more particularly to a multi-process position feeding pretreatment conveyor line, belonging to the field of food production and processing technology. Background Technology

[0002] In the food processing industry, meat needs to be transported from the warehouse to different processing stations according to the processing requirements. Traditionally, this has involved using forklifts or manual labor to move the meat to various processing equipment. This method is not only labor-intensive but also increases workload and difficulty. Furthermore, manual handling can easily contaminate the work environment and may result in meat being transported to the wrong processing station, leading to food safety hazards.

[0003] A search reveals that Chinese patent document CN202220177509.3 discloses a frozen meat unpacking production equipment, consisting of an automatic lifting unpacking platform device, a waste packaging carton recycling device, a frozen meat conveying device, and a frozen meat shelving device. It can achieve fully automatic or semi-automatic frozen meat unpacking processes; however, it is only suitable for conveying and transferring unpacked frozen meat to shelves, and cannot meet the conveying requirements of multiple processes. Furthermore, Chinese patent document CN202310446777.X discloses an intelligent contactless sorting and distribution device and method. This sorting and distribution device includes a fixed frame, with a support frame fixedly connected inside. A food conveyor belt is rotatably connected to one side of the support frame, and a stacking rack is rotatably connected to the other side of the support frame. A moving mechanism is installed on the fixed frame, and a fixed plate is connected to the moving mechanism. A distribution and stacking mechanism is connected to the fixed plate. The delivery rollers rise and contact the meat stacked on the stacking rollers, causing the meat to move synchronously. The moving mechanism drives the delivery and stacking mechanism into the delivery box. When the U-shaped frame contacts the delivery box, the fixed plate and the driving rod push the pulley, causing multiple delivery rollers to move towards the vertical parts of the L-shaped grooves on both sides. After the delivery rollers disengage from the meat, the meat can be neatly stacked in the delivery box, improving work efficiency. However, this technical solution only solves the problem of meat delivery and stacking and still cannot meet the conveying requirements of multiple process routes. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by proposing a multi-process position feeding pretreatment conveyor line that can transport materials to various process equipment, thereby facilitating the flexible and efficient completion of complex processes.

[0005] To achieve the above objectives, the basic technical solution of the meat pre-processing conveyor line of the present invention is as follows: it includes at least two sets of telescopic conveyor units arranged between the head horizontal conveyor unit and the tail horizontal conveyor unit along the main conveying direction, and each telescopic conveyor unit is respectively configured with a lifting conveyor unit connected to it on one side. The head horizontal conveying unit and the tail horizontal conveying unit are each composed of a conveyor belt located on a corresponding support frame; The telescopic conveyor unit includes a front upper conveyor unit fixing rod, a front lower conveyor unit fixing rod, a middle drive wheel assembly, and optical shafts supported on both sides of the corresponding support frame, as well as a horizontally telescopic cylinder located between the two optical shafts. The optical shafts and the corresponding support frame form a horizontal moving pair, and the telescopic end of the cylinder is connected to a follower metal plate. The follower metal plate is fixed to the optical shaft and supports a front lower follower fixing rod, a rear upper follower fixing rod, and a rear lower follower fixing rod, respectively. The telescopic conveyor belt passes through the front upper conveyor unit fixing rod, the rear upper follower fixing rod, the rear lower follower fixing rod, and the front lower follower fixing rod, bends at an S-shape around the drive wheel assembly, and then passes through the front lower conveyor unit fixing rod to the front upper conveyor unit fixing rod, forming a closed loop structure. The lifting and conveying unit consists of a conveyor belt with a horizontal section and an inclined section supported on a corresponding support frame. The horizontal section and the inclined section are kept taut and tensioned by the conveyor unit pressure rollers supported on the corresponding support frame. The horizontal section is attached to the retracted and recessed part of the telescopic conveying unit.

[0006] During conveying, the telescopic conveyor unit can be in the extended state to realize straight conveying from the head horizontal conveyor unit to the tail horizontal conveyor unit along the main conveying direction; it can also be in the retracted state as needed, so that the conveyed material falls from the head horizontal conveyor unit to the lifting conveyor unit through the retracted clearance of the telescopic conveyor unit and is transferred to the predetermined process equipment position midway, thus flexibly meeting the conveying requirements of multiple process routes. It has significant advantages such as reasonable structure, space saving, and flexible modular combination.

[0007] A further improvement to the present invention is that the horizontal section and the inclined section are kept taut and tensioned by the pressure rollers of the conveying unit supported on the corresponding support frame.

[0008] A further improvement to the present invention is that the head horizontal conveying unit, the tail horizontal conveying unit, the telescopic conveying unit, and the lifting conveying unit are each equipped with a water washing spray pipe.

[0009] A further improvement to the present invention is that a water washing spray pipe is installed above the conveyor belt of the head horizontal conveyor unit, and a water washing spray pipe is installed below the conveyor belts of the lifting conveyor unit, the telescopic conveyor unit and the tail horizontal conveyor unit.

[0010] A further improvement to the present invention is that a water-blowing air knife is installed after the water washing spray pipe.

[0011] A further improvement to the present invention is that the middle part of the optical axis is slidably fitted with a straight unit bearing positioned on the corresponding support frame, thereby forming a horizontal moving pair with the support frame. Attached Figure Description

[0023] The basic structure of the multi-process position feeding meat pre-processing conveyor line in this embodiment is as follows: Figure 1 As shown, it includes four sets of telescopic conveying units 3 arranged between the head horizontal conveying unit 2 and the tail horizontal conveying unit 10 along the main conveying direction, and each telescopic conveying unit 3 is equipped with a lifting conveying unit 4 connected to it on one side.

[0024] The specific structure of the head horizontal conveying unit 2 is as follows: Figure 2 , Figure 3 As shown, it mainly consists of a conveyor belt located between fixed metal plates 9 on both sides of the support frame 1. The conveyor belt is driven by a variable frequency motor 7 through a motor drive shaft 13. A set of water washing spray metal pipes 5 is installed above the front section of the conveyor belt, and a set of water blowing knives 6 is installed above the rear section of the conveyor belt, supported by adjustable height water blowing air knife brackets 14 on both sides, which can be used for water blowing cleaning after water washing.

[0025] The specific structure of the telescopic conveyor unit 3 is as follows: Figure 4 , Figure 5As shown, the system includes upper and lower conveyor unit fixing rods 17 installed at the front of the support frame 1, a drive sprocket assembly 23 in the middle, and optical shafts 20 supported on both sides by optical shaft brackets 21 and a horizontally telescopic cylinder 19 located between the two optical shafts 20. The middle part of the optical shaft 20 is slidably engaged with the straight unit bearing 22 installed on the support frame 1. The telescopic end of the cylinder 19 is connected to the follower metal plates 9-1 on both sides through the cylinder optical shaft connecting rod 27. The follower metal plates 9-1 are fixed to the optical shaft 20. The lower front part and the upper and lower rear parts of the follower fixing rods 17-1 respectively support the follower fixing rods 17-1. The telescopic conveyor belt passes through the upper front conveyor unit fixing rod 17, the upper rear follower fixing rod 17-1, the rear follower fixing rod 17-1, and the front follower fixing rod 17-1, then bends at S around the sprocket assembly 23, and then passes through the lower front conveyor unit fixing rod 17 to the upper front conveyor unit fixing rod 17, forming a closed loop structure. Therefore, under the horizontal extension and retraction of cylinder 19, the conveyor belt can extend or shorten as needed due to the movement of the follower metal plate 9-1, while maintaining tension. A water-washing spray metal pipe 5 and a water-blowing air knife 6 are installed at intervals below the conveyor belt between the sprocket assembly 23 and the front lower conveyor unit fixing rod 17. A water receiving tray 8 is installed at the lower part of the support frame 1.

[0026] The specific structure of the lifting conveyor unit 4 is as follows: Figure 6 As shown, the conveyor belt drive supported on the support frame 1 consists of a horizontal section and an inclined section. The horizontal section and the inclined section are kept taut by the conveyor unit pressure roller 25 supported on the support frame 1, and the horizontal section is positioned at the retraction point of the telescopic conveyor unit 3. The spray metal pipe 5, the water blowing knife 6, and the water receiving tray 8 are respectively installed below the conveyor belt.

[0027] The specific structure of the tail horizontal conveying unit 10 is as follows: Figure 7 As shown, it consists of a horizontal conveyor belt supported on support frame 1, and its output end can be as follows: Figure 1 As shown, a lifting and conveying unit 4 or other subsequent devices can be configured and connected as needed. The spray metal pipe 5, the water-blowing air knife 6, and the water receiving tray 8 are respectively installed below the conveyor belt.

[0028] Other secondary structures are clearly visible in the attached drawings, and therefore will not be described in detail. During operation, the telescopic conveyor unit 3 in this embodiment is in... Figure 8 When the telescopic conveyor unit 3 is in the extended state as shown, the meat is conveyed to the next working section. Figure 9When retracted, the meat falls onto the corresponding lifting conveyor unit 4 and is transported to the appropriate process stage. This constitutes a meat pre-processing conveyor unit that can be freely combined to meet various meat processing needs. In use, according to the processing requirements, multiple telescopic conveyor units or a single telescopic conveyor unit can be used simultaneously or sequentially to transport the required meat according to various set task modes. This allows the conveyor unit to form a meat pre-processing conveyor unit that can transport meat for various processing processes, efficiently and quickly completing the meat transport. During the transport process, the first spray metal water pipe can be opened to clean the meat. After cleaning, the metal air duct can be opened to treat the ice water generated from incomplete thawing and the water remaining from cleaning. After the transport task is completed, the spray metal water pipe installed on the conveyor unit can be opened to clean the conveyor unit.

[0029] Compared with the prior art, this embodiment has the following significant advantages: 1) It can be flexibly combined with various process equipment through unit combination according to the needs of processing tasks; 2) It has a self-cleaning function; 3) The conveying speed of the head horizontal conveyor unit can be intelligently adjusted according to the processing task requirements. The conveyor line control system and the water control system are linked to adjust the spray water temperature to achieve the best process temperature matching for cold processing. 4) Depending on the processing task requirements, the telescopic conveyor unit can be controlled to achieve timed or quantitative sorting and conveying through the linkage between the conveyor line control system and the process equipment.

[0030] In addition to the embodiments described above, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
