Description

Technical Field

[0001] This utility model belongs to the field of material feeding technology, specifically a three-layer drawer-type feeding mechanism. Background Technology

[0002] In the field of material unloading, traditional drawer-type unloading mechanisms mostly use cylinders as the power source for control. However, there are many limitations to using a drive: on the one hand, cylinders are large in size and occupy a lot of space, which limits the installation layout. Usually, only one cylinder can be installed on one side, and at most two can be installed; on the other hand, cylinders are prone to generating a lot of noise when they are working.

[0003] Meanwhile, traditional drawer-type feeding mechanisms can mostly only achieve two-layer feeding, lacking a structure for pre-storing materials in the middle. This results in an unsmooth connection between the feeding and feeding stages, often leading to material supply interruptions or accumulation, further restricting the feeding speed. In addition, for thin and light materials packaged in multiple trays per box, traditional mechanisms struggle to achieve stable stacking feeding, resulting in a single feeding layer and low feeding efficiency, failing to meet the requirements of high-efficiency production. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a three-layer drawer-type feeding mechanism.

[0005] The technical solution adopted by this utility model is as follows: a three-layer drawer-type unloading mechanism, including a fixed upright plate, a transmission component and a drive component for driving the transmission component are installed on one side of the fixed upright plate, and an unloading component and a limiting component are installed on the other side; the transmission component includes an eccentric wheel, the eccentric wheel is rotatably connected to a connecting rod through a fisheye joint, the end of the connecting rod is rotatably connected to a driving rack through a fisheye joint, the driving rack is meshed with a gear, the gear is meshed with a driven rack, and the driven rack and the driving rack are arranged parallel and symmetrically on both sides of the gear, the gear is rotatably mounted on the fixed upright plate through a bearing, and connecting parts are installed on both the driving rack and the driven rack. The fixed upright plate has an oblong hole, and both connecting parts pass through the oblong hole and are clearance-fitted with the oblong hole;

[0006] The feeding assembly includes two right-angle fixing seats, which are symmetrically installed on two connecting parts. Each right-angle fixing seat is equipped with a feeding fixing plate, and each feeding fixing plate is equipped with a material support plate. The two material support plates are symmetrically arranged with the gear as the center.

[0007] Furthermore, the limiting component includes two sliders, which are respectively mounted on two right-angle fixed seats. Both sliders are connected to a slide rail, which is mounted on a fixed upright plate.

[0008] Furthermore, the drive assembly includes a motor, and a reducer is installed at the output end of the motor. The output end of the reducer passes through the motor mounting plate and is fixedly connected to the eccentric wheel. The motor mounting plate is installed on the fixed upright plate.

[0009] Furthermore, the transmission assembly, the feeding assembly, and the limiting assembly are all provided in three sets, and the three sets of transmission assemblies, feeding assemblies, and limiting assemblies are all arranged at equal intervals along the height direction of the fixed upright plate.

[0010] Furthermore, the drive components for driving the transmission assembly are provided in three sets, and the three sets of drive components are arranged in an alternating manner.

[0011] Furthermore, a material drop guide assembly is provided above the material support plate. The material drop guide assembly includes two support seats mounted on a fixed upright plate. Side baffles are vertically mounted on both support seats. The two side baffles are symmetrically arranged about the gear. A connecting plate is installed between the two support seats. A rear baffle is installed on the connecting plate. The rear baffle is vertically arranged between the two side baffles. A front baffle is also installed on the fixed upright plate.

[0012] Furthermore, the material support plate is provided with a clearance groove, the lower end of the side baffle is strip-shaped, and the lower end of the side baffle is in clearance fit with the clearance groove.

[0013] Furthermore, a protective cover is also installed on the fixed plate to protect the transmission components.

[0014] Furthermore, the protective cover has clearance holes to allow the motor mounting plate to pass.

[0015] Furthermore, a mounting base is also installed on the fixed upright plate.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] This three-layer drawer-type feeding mechanism replaces the existing cylinder drive with a motor drive. The compact size of the servo motor allows for separate servo motors to be installed on both sides of the fixed upright plate, breaking the layout limitations of the existing cylinder drive and enabling three-layer feeding. The middle layer can be used to pre-store materials, making the connection between the feeding and feeding rings tighter and more stable, avoiding material supply interruptions or accumulation, and indirectly improving feeding speed. It is particularly suitable for thinner, lighter materials, and materials packaged in multiple trays, enabling stacked feeding. The three-layer feeding structure forms a clear feeding hierarchy, allowing for simultaneous or orderly feeding of multiple groups of materials, significantly improving feeding efficiency.

[0018] At the same time, it eliminates the need for air supply equipment for cylinders and removes the air filling process, which not only reduces the purchase and maintenance costs of the equipment, but also reduces energy consumption, making it more energy-efficient and environmentally friendly.

[0027] The following is combined with Figures 1-3 This utility model will be described in detail.

[0028] Example

[0029] Depend on Figure 1-3 It is known that a three-layer drawer-type feeding mechanism has the following structure: the mechanism includes a fixed upright plate 1, a transmission component 2 and a drive component 5 for driving the transmission component 2 are installed on one side of the fixed upright plate 1, and a feeding component 3 and a limiting component 4 are installed on the other side.

[0030] The transmission assembly 2 consists of an eccentric wheel 201, a connecting rod 202, a driving rack 203, a gear 204, a driven rack 205, and a connecting member 206. The eccentric wheel 201 is rotatably connected to the connecting rod 202 via a fisheye joint, and the end of the connecting rod 202 is also rotatably connected to the driving rack 203 via a fisheye joint. The driving rack 203 meshes with the gear 204, and the gear 204 meshes with the driven rack 205. The driven rack 205 and the driving rack 203 are symmetrically distributed on both sides of the gear 204.

[0031] Gear 204 is rotatably mounted on fixed plate 1 via bearings. Connecting members 206 are mounted on both the driving rack 203 and the driven rack 205. A slotted hole 207 is provided on fixed plate 1, through which both connecting members 206 pass, forming a clearance fit. The slotted hole 207 provides a constraint on the motion trajectory of the connecting members 206 and reduces motion interference through the clearance fit, ensuring transmission accuracy.

[0032] The drive assembly 5 includes a motor 501, and a reducer 502 is installed at the output end of the motor 501. The output end of the reducer 502 passes through the motor fixing plate 503 and is fixedly connected to the eccentric wheel 201. The motor fixing plate 503 is installed on the fixed upright plate 1.

[0033] After the motor 501 is reduced in speed and increased in torque by the reducer 502, it directly drives the eccentric wheel 201 to rotate. The eccentric wheel 201 is rotatably connected to the connecting rod 202 and the driving rack 203 through the double fisheye joint structure, which converts the rotational motion of the motor 501 into the linear reciprocating motion of the driving rack 203, and then transmits it to the gear 204 to realize the reverse synchronous linear reciprocating motion of the driven rack 205.

[0034] The transmission assembly 2 is provided in three sets, which are equidistantly arranged along the height direction of the fixed vertical plate 1, corresponding to the upper, middle and lower layer feeding operations respectively, realizing independent control of each layer. Correspondingly, the three sets of transmission assemblies 2 correspond to the upper, middle and lower layer feeding assemblies 3 respectively.

[0035] Similarly, each transmission component 2 is controlled by the drive component 5. The three drive components 5 are arranged in a staggered manner on the fixed vertical plate 1. The staggered distribution reduces the vertical space occupation and significantly improves the space utilization while ensuring independent drive function.

[0036] The feeding assembly 3 includes two right-angle fixing seats 301, which are symmetrically mounted on two connectors 206. Each right-angle fixing seat 301 is equipped with a material dropping fixing plate 302, and the material dropping fixing plate 302 is equipped with a material support plate 303. The two material support plates 303 are symmetrically arranged with the gear 204 as the center, forming a stable support for the material.

[0037] The material support plates 303 of the upper and lower layer feeding components 3 are responsible for performing the material feeding operation, and the material is released by moving in opposite directions or in reverse. The material support plates 303 of the middle layer feeding component 3 undertake the material pre-storage function, temporarily storing the materials to be processed, and realizing the continuous supply of materials.

[0038] The limit component 4 is also set for the three sets of feeding components 3. The limit component 4 provides guidance and constraint for the movement of the feeding components 3, ensuring that it runs smoothly and reliably.

[0039] Each set of limiting components 4 includes two sliders 401 and a slide rail 402. The sliders 401 are mounted on the right-angle fixed base 301 and are connected to the slide rail 402 mounted on the fixed upright plate 1. The linear guide restricts the movement freedom of the feeding component 3, avoids deviation or jamming during transmission, and improves the running accuracy of the mechanism.

[0040] To ensure that the material from the previous process falls accurately onto the material support plate 303 of this mechanism, a material drop guide component 6 is provided above the material support plate 303.

[0041] The component includes two support bases 601 mounted on a fixed upright plate 1. Each support base 601 has a side baffle 603 vertically mounted on it. The two side baffles 603 are symmetrically arranged about the gear 204 and are respectively clearance-fitted with two material support plates 303. A connecting plate 602 is installed between the two support bases 601, and a rear baffle 604 is mounted on the connecting plate 602, vertically positioned between the two side baffles 603. A front baffle 605 is also mounted on the fixed upright plate 1, parallel to the rear baffle 604.

[0042] The support base 601 and the connecting plate 602 serve to support and fix the two side baffles 603 and the rear baffle 604. The front baffle 605, the rear baffle 604 and the two side baffles 603 form constraints in the front-back and left-right directions, together forming a rectangular limiting space for the material, ensuring that the material is discharged within the predetermined path.

[0043] Meanwhile, the material support plate 303 is provided with a clearance groove, and the lower end of the side baffle 603 is strip-shaped, and the lower end of the side baffle 603 is fitted with the clearance groove with a gap, so that the side baffle 603 will not interfere with the normal opening and unloading operation of the material support plate 303.

[0044] A protective cover 7 is also installed on the fixed upright plate 1 to protect the transmission assembly 2. The protective cover 7 has clearance holes to avoid the motor mounting plate 503. The protective cover 7 protects the transmission assembly 2, preventing external dust and debris from entering and affecting the normal operation of the transmission components in the transmission assembly 2, thus extending its service life. At the same time, it avoids contact between operators and transmission components, improving the safety of the entire mechanism.

[0045] In addition, a mounting base 8 is installed on the fixed plate 1. The mounting base 8 is used to fix the entire mechanism to the target equipment to ensure structural stability during operation.

[0046] Specifically, when using this three-layer drawer-type feeding mechanism,

[0047] Initial state: All three sets of material feeding components' support plates 303 are in a closed state (i.e., two support plates 303 are close to each other, forming a support surface). The upper and lower support plates 303 are waiting to receive the material to be fed, while the middle support plate 303 is in a pre-stored material state.

[0048] Power input: When a material unloading operation is required on a certain layer, the corresponding drive component 5 is activated. The motor 501 drives the eccentric wheel 201 to rotate through the reducer 502. The circular motion of the eccentric wheel 301 is converted into the linear reciprocating motion of the drive rack 203 through the connecting rod 202.

[0049] Transmission linkage: The driving rack 203 drives the gear 204 to rotate, and the gear synchronously drives the driven rack 205 to perform a reverse linear motion (opposite to the direction of motion of the driving rack 203). Through the transmission of the connecting piece 206, the motion of the driving rack 203 and the driven rack 205 is synchronously transmitted to the right-angle fixed seat 301 of the unloading assembly 3.

[0050] Material feeding execution: Under the guidance of the slider 401 and slide rail 402 of the limiting component 4, the two right-angle fixed seats 301 drive the material support plate 303 to perform reverse separation movement. The material originally supported on the material support plate 303 loses its support and is fed through the limiting space of the material feeding guide component 6 under the action of gravity.

[0051] Reset and Cycle: After the material is unloaded, the drive assembly drives the eccentric wheel 301 to rotate in the opposite direction, and the transmission system resets and closes the material support plate 303. If continuous operation is required, the equipment will cycle through the above steps according to the preset program. The intermediate layer can transport the pre-stored material to the upper and lower layers as needed to achieve continuous material supply and unloading.

[0052] 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.
