Description

Technical Field

[0001] This utility model relates to the field of egg carton feeding technology, specifically to a feeding device for an egg carton punching machine. Background Technology

[0002] In the egg carton processing industry, punching machines need to precisely drill holes in specific locations within the egg carton to meet packaging or ventilation requirements. Traditional feeding devices mostly rely on manual layer-by-layer feeding, which is inefficient and inconsistent, making it difficult to adapt to the needs of large-scale production. While existing automated feeding technologies can achieve stacked conveying of egg cartons, they still have significant drawbacks: First, fixed limiting structures cannot accommodate the size differences of egg cartons of different specifications, limiting the equipment's versatility; second, mechanical impacts during egg carton separation can easily cause deformation or positioning misalignment, affecting subsequent punching accuracy; third, conveying mechanisms mostly use rigid transmissions, lacking buffer protection, making egg cartons susceptible to damage from vibration or collisions. With the increasing trend towards lightweight materials and diversified structures in egg cartons, the market urgently needs a feeding device for egg carton punching machines to solve the problem of low efficiency. Utility Model Content

[0003] To address the aforementioned issues, a feeding device for an egg carton punching machine is provided. A first motor drives a retracting separating rod, causing the bottom egg carton to detach from its support and fall into the conveying mechanism under gravity, where it is transferred to the punching station. After the rod resets, the upper egg carton automatically fills the gap, forming a continuous separation-conveyor cycle. Combined with the adjustability of the limit rod and the precise movement of the separating rod, fully automatic and efficient feeding is achieved, solving the problem of low efficiency caused by manual labor in existing devices.

[0004] To address the problems of existing technologies, this utility model provides a feeding device for an egg carton punching machine, comprising a frame, an automatic feeding mechanism, and a conveying mechanism. The automatic feeding mechanism includes a mounting bracket mounted on the frame, with several L-shaped mounting bases on its four sides. Several threaded holes are formed on the sidewalls of the L-shaped mounting bases perpendicular to the mounting bracket. Several limiting rods are mounted on the sidewalls of the L-shaped mounting bases perpendicular to the mounting bracket, with threaded holes at their mounting points on the vertical sides of the L-shaped mounting bases. The limiting rods are mounted to the L-shaped mounting bases using bolts. A first motor is mounted at the bottom of the mounting bracket, and the output shaft of the first motor is connected to a separating rod for separating egg cartons. The conveying mechanism is mounted on the frame. When the separating rod separates multiple egg cartons located between the limiting rods, the lowest egg carton falls into the conveying mechanism.

[0005] Preferably, the mounting bracket is equipped with a second motor at both ends, and the output shaft of the second motor is connected to a clamping plate. When the separation rod retracts and the egg box loses its support, the second motor drives the clamping plate to move in opposite directions to clamp the egg box.

[0006] Preferably, the bottom of the L-shaped mounting base is provided with a mounting hole, and the L-shaped mounting base is mounted on the mounting bracket by bolts.

[0007] Preferably, the conveying mechanism includes a guide rail disposed on the surface of the frame, a conveying platform slidably connected to the guide rail, and a guide groove adapted to the guide rail being provided at the bottom of the conveying platform.

[0008] Preferably, a buffer pad is installed on the conveying platform.

[0009] Preferably, the conveying platform has threaded holes at its four corners, and the buffer pad has mounting holes at positions corresponding to the threaded holes. The buffer pad is mounted on the conveying platform by bolts.

[0010] Preferably, the buffer pad is an upwardly convex boss structure that is adapted to the concave shape of the egg carton.

[0011] Preferably, the conveying platform is driven by a servo motor.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. In this utility model, the synergistic action of the limiting rod and the separating rod of the automatic feeding mechanism solves the problem that the existing egg carton punching machine requires manual placement of each egg, which is time-consuming and labor-intensive, and greatly improves the feeding efficiency.

[0014] 2. In this utility model, a clamping plate and a buffer pad are provided in the conveying mechanism. The clamping plate clamps the egg carton at the moment of its fall to ensure the stability of the vertical falling path of the egg carton; the buffer pad absorbs the impact force when the egg carton falls, preventing the egg carton from being damaged or displaced due to hard collision, thereby improving the stability of feeding and the integrity of the egg carton.

[0015] 3. The conveying platform in this utility model is driven by a servo motor, which realizes precise control of the position and speed of the egg carton conveying, ensuring that the egg carton is accurately and stably conveyed to the subsequent punching station, thereby improving the automation level and processing accuracy of the entire egg carton punching machine.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-6 As shown: A feeding device for an egg carton punching machine includes a frame 1, an automatic feeding mechanism 2, and a conveying mechanism 3. The automatic feeding mechanism 2 includes a mounting bracket 21 mounted on the frame 1. The mounting bracket 21 has several L-shaped mounting bases 22 on its four sides. Several threaded holes are opened on the side wall of the L-shaped mounting bases 22 perpendicular to the mounting bracket 21. Several limiting rods 23 are installed on the side wall of the L-shaped mounting bases 22 perpendicular to the mounting bracket 21. Threaded holes are opened at the mounting points of the limiting rods 23 and the vertical sides of the L-shaped mounting bases 22. The limiting rods 23 are installed on the L-shaped mounting bases 22 by bolts. A first motor 24 is installed at the bottom of the mounting bracket 21. The output shaft of the first motor 24 is connected to a separating rod 25 for separating egg cartons. The conveying mechanism 3 is located on the frame 1. When the separating rod 25 separates multiple egg cartons located between the limiting rods 23, the egg carton at the bottom falls into the conveying mechanism 3.

[0025] In existing technologies, egg carton punching machines require manual placement of each carton, which is time-consuming and labor-intensive. To solve this problem, in this device, egg cartons are first stacked within the space formed by the limiting rod 23 of the automatic feeding mechanism 2. The limiting rod 23 is positionally adjusted via threaded holes on the L-shaped mounting base 22 to accommodate the positioning requirements of egg cartons of different sizes. After the first motor 24 at the bottom of the mounting bracket 21 starts, it drives the separation rod 25 to reciprocate. When the separation rod 25 retracts, it separates the bottommost egg carton from its upper layer. At this time, the egg carton, having lost the support of the separation rod 25, falls vertically under gravity and lands on the conveying mechanism 3 located on the frame 1. The conveying mechanism 3 then transports the egg carton to the subsequent punching station via a transmission component, while the group of egg cartons above the limiting rod 23 is re-securely supported after the separation rod 25 resets, forming a continuous separation-falling-conveying cycle. Throughout the process, the modular installation design of the limiting rod 23 and the insertion and removal action of the separating rod 25 work together to ensure the layer-by-layer separation and efficient transport of the egg box.

[0026] Reference Figures 1-4 As shown: The mounting bracket 21 is equipped with a second motor 26 at both ends. The output shaft of the second motor 26 is connected to a clamping plate 27. When the separation rod 25 retracts and the egg box loses its support, the second motor 26 drives the clamping plate 27 to move towards each other to clamp the egg box.

[0027] When the separating rod 25 completes a single separation action and retracts, the egg carton, which was originally supported, is briefly in a free-falling state. At this time, the second motors 26 at both ends of the mounting bracket 21 start synchronously, driving the clamping plates 27 connected to the output shaft to move in opposite directions, quickly applying clamping force to both sides of the egg carton that is about to fall. The clamping action of the clamping plates 27 is triggered the instant the egg carton is released from the support of the separating rod 25, and the clamping and positioning prevents the egg carton from falling continuously, ensuring the stability of the vertical falling path of the egg carton. After completing the brief fixation, the clamping plates 27 move in the opposite direction with the second motor 26 to reset, releasing the egg carton so that it falls accurately into the conveying mechanism 3, while reserving space for the next separation action.

[0028] Reference Figures 1-4 As shown: The bottom of the L-shaped mounting base 22 is provided with mounting holes, and the L-shaped mounting base 22 is mounted on the mounting bracket 21 by bolts.

[0029] In this feeding device, the bottom of the L-shaped mounting base 22 forms a modular connection structure with the mounting bracket 21 through the opening of the mounting hole.

[0030] Reference Figure 5 and Figure 6 As shown: The conveying mechanism 3 includes a guide rail 31 disposed on the surface of the frame 1, and a conveying platform 32 is slidably connected to the guide rail 31. The bottom of the conveying platform 32 is provided with a guide groove 33 adapted to the guide rail 31.

[0031] After the separating rod 25 separates the bottom egg carton and causes it to fall, the egg carton falls vertically onto the surface of the conveying platform 32. The guide groove 33 at the bottom of the conveying platform 32 slides into the guide rail 31 on the surface of the frame 1, forming a linear sliding constraint structure to ensure that the conveying platform 32 can only move horizontally along the preset path of the guide rail 31.

[0032] Reference Figure 5 and Figure 6 As shown: A buffer pad 34 is installed on the conveying platform 32.

[0033] When the separated egg carton falls vertically from the space between several limit rods 23 to the conveyor platform 32, the buffer pad 34 absorbs the impact force of the egg carton when it comes into contact with the platform by its elastic deformation, effectively preventing the egg carton from being damaged or displaced due to hard collision.

[0034] Reference Figure 5 and Figure 6 As shown: The conveying platform 32 has threaded holes at its four corners, and the buffer pad 34 has mounting holes at positions corresponding to the threaded holes. The buffer pad 34 is mounted on the conveying platform 32 by bolts.

[0035] After the pre-drilled threaded holes at the four corners of the conveyor platform 32 are precisely aligned with the corresponding mounting holes of the buffer pad 34, the bolts pass through the mounting holes of the buffer pad 34 and are screwed into the threaded holes to fasten the buffer pad 34 to the platform surface.

[0036] Reference Figure 5 and Figure 6 As shown: The buffer pad 34 is an upwardly protruding boss structure, which is adapted to the concave shape of the egg carton.

[0037] The buffer pad 34 of the feeding device adopts an upwardly protruding boss structure, which enhances the positioning and cushioning effect of the egg carton through contour design. After the egg carton falls from between the limiting rods 23, the concave shape of its bottom fits into the boss structure on the surface of the buffer pad 34, and the top of the boss is embedded in the groove of the egg carton to form a physical limit, restricting the egg carton's freedom in the horizontal direction and preventing it from shifting due to inertia or vibration during the conveying process.

[0038] The conveying platform 32 is driven by a servo motor.

[0039] The conveying platform 32 of the feeding device achieves precise control of the position and speed of egg carton conveying through the precision drive of a servo motor. After the servo motor is connected to the transmission structure of the conveying platform 32, such as a lead screw, belt or gear set, its output shaft outputs a specific speed and direction according to a preset program, driving the conveying platform 32 to perform linear reciprocating motion along the guide rail 31.

[0040] Working Principle: After the device is started, the egg cartons are stacked within the space formed by the limiting rod 23 of the automatic feeding mechanism 2. The position of the limiting rod 23 can be adjusted via the threaded hole on the L-shaped mounting base 22 to accommodate the positioning requirements of egg cartons of different sizes. The first motor 24, located at the bottom of the mounting bracket 21, drives the separating rod 25 to reciprocate. When the separating rod 25 retracts, it separates the bottommost egg carton from its upper layer. At this moment, the egg carton, having lost the support of the separating rod 25, falls vertically under the influence of gravity. Just before the egg cartons fall, the second motors 26 at both ends of the mounting bracket 21 start synchronously, driving the clamping plates 27 to move towards each other and clamp the egg cartons.

[0041] The conveying mechanism 3 includes a guide rail 31 mounted on the surface of the frame 1 and a conveying platform 32 slidably connected to the guide rail 31. The bottom of the conveying platform 32 has a guide groove 33 adapted to the guide rail 31, forming a linear sliding constraint structure to ensure that the conveying platform 32 can only move horizontally along the preset path of the guide rail 31. When the egg carton falls into the conveying platform 32, the conveying platform 32 achieves precise control of the position and speed of the egg carton conveying through the precision drive of a servo motor. After the servo motor is connected to the transmission structure of the conveying platform 32, its output shaft outputs a specific speed and direction according to a preset program, driving the conveying platform 32 to perform linear reciprocating motion along the guide rail 31, conveying the egg carton to the subsequent punching station.

[0042] In addition, a buffer pad 34 is installed on the conveyor platform 32 to absorb the impact force when the egg carton falls, preventing damage or displacement of the egg carton due to hard collisions. The buffer pad 34 is installed on the conveyor platform 32 by bolts, and the pre-drilled threaded holes at its four corners are precisely aligned with the corresponding mounting holes on the buffer pad 34. The buffer pad 34 adopts an upward-protruding boss structure, which is adapted to the concave shape of the egg carton, further enhancing the positioning and cushioning effect of the egg carton.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
