TECHNICAL FIELD
[0001] The application relates to the technical field of egg packaging, and particularly discloses an egg tray conveying structure. BACKGROUND
[0002] Eggs are a kind of household food materials, and the production and packaging of eggs have realized farm production and mechanized packaging. In order to ensure the integrity of eggs during conveying and storage, egg trays are commonly used for packaging and conveying eggs.
[0003] In the prior art, empty egg trays are sequentially placed into an egg tray conveying structure, and then the conveying of the egg trays is completed by the egg tray conveying structure until the egg trays are sent to an egg loading station.
[0004] The existing egg tray conveying structure is improved from a belt conveying structure and mainly comprises rotating shafts installed on the two sides of a rack, belt wheels coaxially and fixedly installed on the rotating shafts, a belt meshed between the two belt wheels, and a plurality of positioning pins fixedly installed on the belt at equal intervals. After the egg trays are placed on the belt, the conveying of the egg trays is realized by the friction between the belt and the bottom of the egg trays and the pushing force of the positioning pins located at the bottom of the egg trays and behind the egg trays during synchronous movement with the belt.
[0005] However, the number of eggs stored in the egg trays is different, and therefore the size, depth and height of each type of egg tray are different. The position of the positioning pin installed on the belt of the traditional egg tray conveying structure is fixed, and the spacing between the egg grooves of different types of egg trays is different. The fixed spacing of the positioning pin has limitations and cannot adapt to the conveying of egg trays of multiple specifications.
[0006] Therefore, the inventor provides an egg tray conveying structure to solve the above problems. CONTENT OF THE UTILITY MODEL
[0007] The utility model aims at solving the problem that the position of the positioning pin installed on the belt of the traditional egg tray conveying structure is fixed, the use has limitations, and multiple specifications of egg trays cannot be conveyed.
[0008] In order to achieve the above purpose, the basic scheme of the utility model provides an egg tray conveying structure, which comprises a rack, rotating shafts rotatably connected to the two sides of the rack, belt wheels coaxially and fixedly connected to the rotating shafts, a belt meshed between the two belt wheels, and a driving mechanism arranged on one side of the rack and used for driving the rotating shafts to rotate. A plurality of sliding grooves parallel to the axis direction of the rotating shafts are formed on the belt at equal intervals. A plurality of chains are surrounded outside the belt. A plurality of abutting blocks used for driving the egg trays to move synchronously are arranged on the chains at equal intervals. A plurality of clamping blocks are slidably connected in the sliding grooves on the two sides of the chains. The clamping blocks are attached to the side walls of the adjacent chains, and a positioning mechanism is arranged on the clamping blocks.
[0009] Furthermore, the chain includes a load-bearing section and a connecting section that are hinged together in sequence. The bottom surface of the load-bearing section is in contact with the surface of the belt, and the abutment blocks are all provided on the load-bearing section.
[0010] Furthermore, the abutment includes an abutment platform fixed to the top surface of the bearing section, a slot formed on the top surface of the abutment platform, and an adjustment block detachably connected to the slot.
[0011] Furthermore, the two ends of the groove pass through the two side walls of the belt.
[0012] Furthermore, the inner walls of the slide groove are inclined on both sides, and T-shaped limiting grooves are also opened on the inner walls of the slide groove along the axis of the rotating shaft. The two side walls of the card block are respectively attached to the inner walls of the slide groove, and the two side outer walls of the card block are respectively provided with T-shaped limiting blocks that are slidably connected in the T-shaped limiting grooves.
[0013] Furthermore, the card block has a threaded groove that passes through the T-shaped limiting block, and the positioning mechanism includes a bolt that is threadedly connected to the threaded groove and can abut against the inner wall of the T-shaped limiting groove.
[0014] The principle and effect of this solution are as follows:
[0015] Compared with existing technologies, this utility model adjusts the spacing between chains by adjusting the position of the positioning block in the sliding groove according to the size of the egg tray to be transported and the spacing between the egg slots at the bottom of the egg tray. This allows the abutment block and the adjusting block on the top of the abutment block installed on the chain to be placed into the gap between the egg slots. Then, as the output shaft of the drive motor drives the rotating shaft to rotate, and in turn drives the belt and chain to move synchronously, the egg tray can be transported synchronously. The abutment block at the rear of the egg tray pushes the egg tray to the egg loading station, thus completing the transportation of the egg tray. This solves the problem that the positioning pin installed on the belt in the traditional egg tray transportation structure has a fixed position, which limits its use and cannot be adapted to the transportation of egg trays of various sizes.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0021] The reference numerals in the accompanying drawings of the instruction manual include: frame 1, shaft 2, belt 3, connecting section 4, bearing section 5, locking block 6, platform 7, adjusting block 8, slide groove 9, and limiting groove 10.
[0022] An egg tray transport structure, implementing, for example Figure 1 , Figure 2 and Figure 3 As shown:
[0023] It includes a frame 1, rotating shafts 2 respectively mounted on both sides of the frame 1 and rotatable, pulleys respectively coaxially fixed on the rotating shafts 2, belts 3 meshing between the pulleys on both sides, and a drive mechanism mounted on the left side of the frame 1 to drive the rotating shaft 2 on the left side to rotate.
[0024] Several meshing blocks are formed at equal intervals on the inner side of the belt 3, and each pulley has a meshing groove circumferentially opened to mesh with the meshing blocks. The drive mechanism includes a drive motor fixedly installed on the left side of the frame 1, a main drive pulley coaxially fixed on the output shaft of the drive motor, a secondary drive pulley coaxially fixed on the end of the left rotating shaft 2 extending out of the frame 1, and a drive belt meshing between the main drive pulley and the secondary drive pulley.
[0025] The belt 3 has several grooves 9 evenly spaced and parallel to the axis of the rotating shaft 2. The two ends of the grooves 9 pass through the two side walls of the belt 3. The inner walls of the two sides of the grooves 9 are inclined inward, and T-shaped limiting grooves 10 are also formed on the inner walls of the two sides of the grooves 9 along the axis of the rotating shaft 2.
[0026] In this embodiment, the outer side of the belt 3 is also surrounded by three chains, which are installed at equal intervals. Each chain has several blocks installed at equal intervals to drive the egg tray to move synchronously. Specifically, the chain includes a bearing section 5 and a connecting section 4 hinged sequentially. The bottom surface of the bearing section 5 is in contact with the surface of the belt 3, and the blocks are all installed on the bearing section 5. Each block includes a platform 7 welded to the top surface of the bearing section 5, a groove on the top surface of the platform 7, and an adjusting block 8 that engages with the groove. The height of the adjusting block 8 is higher than the height of the platform 7, and during the transport of the egg tray, the top of the adjusting block 8 is in contact with the bottom surface of the gap between the bottom of the egg tray's egg groove. Because the gap between the bottoms of the egg grooves is traditionally recessed, the egg tray can be driven to move synchronously during the movement of the adjusting block 8.
[0027] Furthermore, locking blocks 6 are installed in the slide grooves 9 on both sides of the chain. The locking blocks 6 can slide within the slide grooves 9, and a positioning mechanism is installed between the locking blocks 6 and the adjacent chain side wall. Specifically, T-shaped limiting grooves 10 are also formed on the inner walls of both sides of the slide grooves 9 along the axis of the rotating shaft 2. The two side walls of the locking blocks 6 are respectively attached to the inner walls of both sides of the slide grooves 9, and T-shaped limiting blocks that slide within the T-shaped limiting grooves 10 are integrally formed on the outer walls of both sides of the locking blocks 6.
[0028] Both sides of the locking block 6 have threaded grooves that pass through the T-shaped limiting blocks on the same side. The positioning mechanism includes bolts that are threadedly connected to the threaded grooves and can abut against the inner wall of the T-shaped limiting groove 10.
[0029] When this utility model is used, the spacing between the egg trays is adjusted by adjusting the position of the positioning mechanism and the position of the locking block 6 in the slide 9 according to the size of the egg tray to be transported. This allows the abutment block and the top adjusting block 8 of the abutment block to be placed into the gap between the egg trays. Then, as the output shaft of the drive motor drives the rotating shaft 2 to rotate, and in turn drives the belt 3 and the chain to move synchronously, the egg tray can be transported synchronously. The abutment block behind the egg tray pushes the egg tray to the egg loading station, thus completing the transportation of the egg tray.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
