Description

Technical Field

[0001] This utility model belongs to the technical field of feeding mechanism, specifically to a flip-plate feeding mechanism. Background Technology

[0002] In cartoning machines, the feeding mechanism is a key component for achieving automated material packing. However, traditional cartoning machine feeding mechanisms currently face numerous problems when handling irregularly shaped and heavy materials.

[0003] Traditional feeding mechanisms mostly employ pusher or chute structures. Pusher structures use pushers to eject materials from the hopper; however, this can easily cause jamming of irregularly shaped materials, and uneven force during the pushing process can lead to material damage. Chute structures rely on the material's own weight to slide down the chute; however, for heavier materials, the sliding speed is difficult to control, and collisions with the chute walls can easily cause breakage. Furthermore, it's difficult to guarantee the accuracy of the dropping position, affecting the efficiency of subsequent cartoning processes. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a flip-plate feeding mechanism that can stably and efficiently handle irregularly shaped and heavy materials.

[0005] The technical solution adopted by this utility model is as follows: a flip-type unloading mechanism includes a mounting plate, a lifting plate slidably connected to the mounting plate, a flipping component and a motor for driving the flipping component are installed on one side of the lifting plate, and an unloading component connected to the flipping component is installed on the other side of the lifting plate. The unloading component includes two symmetrically arranged hopper plates, which are respectively mounted on two rotating shafts. Both rotating shafts are rotatably mounted on the lifting plate through flange seats. A limit plate is vertically arranged above the side of the two hopper plates near the rotating shafts. Support plates are installed at both ends of the limit plates and are fixedly connected to the lifting plate. Guardrails are installed on both support plates through fixed seats.

[0006] Furthermore, the two guardrails are symmetrically distributed, and the two guardrails and the limiting plate surround each other to form a material turning channel.

[0007] Furthermore, the flipping assembly includes an eccentric wheel installed at the motor output end. The eccentric wheel is rotatably connected to a connecting rod via a spherical bearing. The end of the connecting rod is rotatably connected to a linking rod via a spherical bearing. The linking rod is rotatably connected to a main gear. The main gear meshes with a secondary gear. The main gear and the secondary gear are respectively fixedly connected to two rotating shafts.

[0008] Furthermore, a locking assembly is also installed on the mounting plate. The locking assembly includes an adjusting block fixedly connected to the mounting plate, a bolt threaded onto the adjusting block, the bolt passing through the adjusting block, and the end of the bolt abutting against the lifting plate.

[0009] Furthermore, both guardrails are tilted outwards on the side away from the pivot, making the inlet of the material turning channel flared.

[0010] Furthermore, a motor plate for fixing the motor is installed on the lifting plate, and a proximity switch is also installed on the motor plate.

[0011] Furthermore, the two mounting bases are respectively equipped with reflectors and photoelectric switches.

[0012] Furthermore, a protective cover for protecting the flipping assembly is provided above the motor plate, and the protective cover is mounted on the lifting plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] This flip-type feeding mechanism uses two symmetrically arranged hopper plates as load-bearing and flipping components. With the drive of the flipping assembly, it can provide stable support for irregularly shaped and heavy materials, and achieve smooth material drop during the flipping process, ensuring high efficiency in material feeding and meeting the continuous production needs of cartoning machines.

[0015] Compared with traditional feeding mechanisms, this mechanism achieves material feeding by flipping the hopper plate. The material is subjected to uniform force during the flipping process, and the material feeding channel formed by the limit plate, guardrail and other components can play a good guiding and protection role for the material, avoiding violent collisions between the material and other components during the feeding process, and effectively reducing the damage to the material.

[0025] The following is combined Figures 1-4 This utility model will be described in detail.

[0026] Example

[0027] Depend on Figure 1-4As can be seen, a flip-type unloading mechanism includes a mounting plate 1. The mounting plate serves as the fixed foundation of the mechanism, supporting the lifting plate and other auxiliary components, and is the installation reference for the entire mechanism. The mounting plate 1 is slidably connected to a lifting plate 2, which can slide up and down along the mounting plate 1 to adjust its height. This can accommodate different boxing heights and reduce the height difference of the flipping and unloading, facilitating stable flipping and unloading by subsequent unloading components. For heavier materials, it can significantly reduce the risk of collisions and deformation caused by excessive acceleration due to gravity.

[0028] A tilting assembly 5 and a motor 3 for driving the tilting assembly 5 are installed on one side of the lifting plate 2, and a feeding assembly 4 connected to the tilting assembly 5 is installed on the other side of the lifting plate 2. Therefore, the lifting plate 2 is the carrier of each assembly, and each assembly slides together with the lifting plate 1 when the lifting plate 2 slides up and down.

[0029] The unloading assembly 4 includes two symmetrically arranged hopper plates 401, which are respectively mounted on two rotating shafts 402. Both rotating shafts 402 are rotatably mounted on the lifting plate 2 via flange seats 403. The rotating shafts 402 are driven by the tilting assembly 5, causing them to rotate around the lifting plate 2 via the flange seats 403. This, in turn, drives the hopper plates 401, which are bolted to the rotating shafts 402, to switch from carrying materials to tilting and unloading.

[0030] Meanwhile, two symmetrically arranged hopper plates 401 jointly support the material, ensuring uniform force and stable rotation during the material's flipping process. Compared to traditional "single-plate" or "push-plate" feeding methods (which are prone to tilting and collisions due to unilateral force), this symmetrical flipping allows the material to fall smoothly along a preset trajectory. Especially for heavier materials, it can significantly reduce the risk of collisions and deformations caused by excessive acceleration due to gravity, achieving "flexible material dropping."

[0031] A limiting plate 404 is vertically installed above the side of the two hopper plates 401 near the rotating shaft 402. The limiting plate 404 is used to limit the position of the material and prevent the material from deviating and leaving the hopper plate 401.

[0032] Both ends of the limiting plate 404 are equipped with support plates 405, which are fixedly connected to the lifting plate 2. Guardrails 406 are installed on both support plates 405 via fixing seats 407. The support plates 405 are used to support and fix the limiting plate 404, the fixing seats 407 and the guardrails 406.

[0033] The two guardrails 406 are symmetrically distributed and are vertically installed at both ends of the limiting plate 404, so that the two guardrails 406 and the limiting plate 404 surround each other to form a material turning channel. This material turning channel can guide and constrain the material to ensure that the material does not deviate from the predetermined trajectory during the turning and unloading process. When installing this mechanism, the turning channel should be aligned with the discharge port of the previous process.

[0034] Furthermore, the two guardrails 406 are both tilted outwards on the side away from the rotating shaft 402, making the inlet of the tipping channel wider. This facilitates the smooth entry of materials into the tipping channel and avoids material jamming.

[0035] The flipping assembly 5 includes an eccentric wheel 501 installed at the output end of the motor 3. The eccentric wheel 501 is rotatably connected to a connecting rod 502 via a spherical bearing. The end of the connecting rod 502 is rotatably connected to a connecting rod 503 via a spherical bearing. The connecting rod 503 is rotatably connected to a main gear 504. The main gear 504 is meshed with a secondary gear 505. The main gear 504 and the secondary gear 505 are respectively fixedly connected to two rotating shafts 402.

[0036] Motor 3 drives eccentric wheel 501 to rotate, which drives connecting rod 502 to reciprocate through spherical bearing. Connecting rod 502 then drives connecting rod 503 through spherical bearing. Connecting rod 503 drives main gear 504 to rotate. Main gear 504 meshes with secondary gear 505, realizing that the two gears rotate synchronously in opposite directions. This drives the rotating shaft 402, which is fixedly connected to main gear 504 and secondary gear 505 respectively, to rotate. Finally, the two hopper plates 401 are symmetrically rotated, completing the material rotation and unloading.

[0037] This method of achieving symmetrical movement of the hopper plate 401 through gear meshing ensures synchronous tilting. The use of spherical bearings reduces jamming during transmission and improves operational flexibility.

[0038] The mounting plate 1 is also equipped with a locking assembly 6, which includes an adjusting block 601 fixedly connected to the mounting plate 1. A threaded bolt 602 is connected to the adjusting block 601, the bolt 602 passes through the adjusting block 601, and the end of the bolt 602 abuts against the lifting plate 2.

[0039] Once the lifting plate 2 has slid to the desired height, tighten the bolt 602 so that its end abuts against the lifting plate 1. The position of the lifting plate 2 is locked by friction to prevent height deviation during operation.

[0040] Meanwhile, the lifting plate 2 can slide along the mounting plate and be fixed by the locking assembly 6, which can be adjusted according to different boxing height requirements, improving the adaptability of the mechanism to boxing equipment and materials of different specifications.

[0041] The lifting plate 2 is equipped with a motor plate 7 for fixing the motor 3. The motor plate 7 is also equipped with a proximity switch 8. The proximity switch 8 is used to detect the position of the motor 3 or the eccentric wheel 501, and to provide feedback action signals to achieve precise control of the flipping action.

[0042] Two fixed bases 407 are respectively equipped with reflectors 9 and photoelectric switches 10. The reflectors 9 and photoelectric switches 10 form a photoelectric detection component, which is used to detect whether there is material in the material turning channel. When the material passes through, it will block the light and trigger the switch signal so as to control the start and stop of the feeding component 4 in time and improve the degree of automation.

[0043] A protective cover 11 for protecting the tilting assembly 5 is provided above the motor plate 7, and the protective cover 11 is installed on the lifting plate 2. The protective cover 11 covers the outside of the tilting assembly to prevent external dust and debris from entering and affecting the normal operation of the transmission components (such as the main gear 504 and connecting rod 502) in the tilting assembly 5, thus extending their service life. At the same time, it avoids contact between operators and transmission components, improving the safety of the entire mechanism.

[0044] Specifically, when using this flip-type feeding mechanism, the material enters the flipping channel through the flared inlet and falls onto the two hopper plates 401. After the photoelectric switch 10 and the reflector 9 detect the material, they send a signal, and the motor 3 prepares to start.

[0045] Motor 3 drives eccentric wheel 501 to rotate, which drives connecting rod 502 to reciprocate through spherical bearing. Connecting rod 502 then drives connecting rod 503 through spherical bearing. Connecting rod 503 drives main gear 504 to rotate. Main gear 504 meshes with secondary gear 505, realizing that the two gears rotate synchronously in opposite directions. This drives the rotating shaft 402, which is fixedly connected to main gear 504 and secondary gear 505 respectively, to flip. Finally, the two hopper plates 401 flip downward, and the material falls onto the conveyor belt of the next process under the action of gravity.

[0046] When motor 3 reverses, hopper plate 401 returns to a horizontal position, ready for the next material; if height adjustment is required, slide lifting plate 2 and then fix it with locking assembly.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
