Description

Technical Field

[0001] The utility model belongs to the technical field of feeding stations, in particular to an auxiliary unloading tool for a feeding station. Background Art

[0002] The auxiliary unloading tooling of the feeding station is mainly designed to solve the problems of material bridging, poor material fluidity, and poor unloading that may occur during the unloading process of large-capacity packaging bags (such as ton bags). It can realize an efficient and automated unloading process and is suitable for all automated production processes that assist in powder feeding.

[0003] Existing auxiliary unloading tooling for feeding stations typically includes a pneumatic cylinder beating mechanism. This mechanism uses the reciprocating motion of the cylinder to beat the bags, breaking up any bridging between materials and promoting smooth material delivery. The pusher on the cylinder uses a horizontal push to beat the bags, resulting in a weak downward force on the materials within the bags, slowing the unloading process.

[0004] Furthermore, the pusher heads used in existing tooling utilize circular flat surfaces, resulting in uneven force at the contact point between the pusher head and the bag, which can affect the life of the cylinder and place greater force on the lower edge of the pusher head, potentially damaging the bag. When multiple cylinders are positioned symmetrically around the bag for beating, the force applied to the material within the bag is concentrated at a single point, which can easily lead to problems such as powder clumping.

[0005] Therefore, how to overcome the above technical defects is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0035] The following will describe in detail the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0036] The core of the present invention is to provide an auxiliary blanking tooling for a feeding station, which can effectively improve the blanking speed.

[0037] To enable those skilled in the art to better understand the technical solution provided by the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Specifically, please refer to Figures 1-7 , an auxiliary blanking tooling for a feeding station provided by the present utility model includes: a support frame 100, a fixed platform, a driving mechanism, and a push head 400.

[0039] The support frame 100 is installed above the feeding station and can provide an installation position for the push head 400 and the driving mechanism. The support frame 100 can be connected to the support components on the feeding station.

[0040] The fixed platform is arranged on the support frame 100 and has an angle with the horizontal plane. One end of the fixed platform close to the ton bag is higher than the other end far from the ton bag. By arranging the fixed platform obliquely, the driving mechanism can drive the push head 400 to apply a slapping force obliquely upward to the ton bag, thereby improving the slapping effect and helping to improve the blanking efficiency. Specifically, the fixed platform can be connected to the support frame 100 by using advanced argon arc welding technology to make the connection firm.

[0041] The settings of the support frame 100 and the fixed platform ensure the stability and load-bearing capacity of the entire auxiliary blanking tooling for the feeding station. The support frame 100 is made of high-strength materials and can resist external forces under various complex environments and usage scenarios, while the steel platform of the feeding station provides a stable operation plane, making the entire blanking process smoother.

[0042] The fixed end of the driving mechanism is arranged on the fixed platform, and the movable end of the driving mechanism is provided with a push head 400. The driving mechanism can drive the push head 400 to perform a linear reciprocating motion, thereby realizing the slapping action of the push head 400 on the ton bag.

[0043] For the auxiliary blanking tooling for the feeding station provided by the present utility model, a support frame 100 is arranged at the ton bag blanking position above the feeding station. The fixed platform is obliquely arranged on the support frame 100. The driving mechanism is installed on the fixed platform, and the movable end of the driving mechanism is provided with a push head 400. The driving mechanism can drive the push head 400 to perform a linear reciprocating motion, thereby realizing the slapping action of the push head 400 on the ton bag. Among them, the support frame 100 ensures the stability and load-bearing capacity of the entire tooling. The fixed platform is arranged obliquely, so that the push head 400 has a certain pushing angle to slap the ton bag, which can improve the falling state and flow condition of the materials in the ton bag, effectively improve the blanking speed, and ensure the accuracy and stability of blanking.

[0044] In a specific embodiment, the support frame 100 comprises a frame structure formed by a plurality of crossbeams arranged end to end. The frame structure has a hollow structure in the middle, through which the falling ton bags of material can fall into the feeding station. The frame structure can be an open frame structure, or a closed frame structure.

[0045] like Figure 1 As shown, the support frame 100 is a rectangular frame structure consisting of four beams. Figure 2 As shown, the support frame 100 includes three crossbeams, forming a U-shaped frame structure with one side open. The open part can be used for operators to operate and observe the unloading status of the ton bag. The support frame 100 can be made of SUS304 material.

[0046] In a specific embodiment, there are multiple fixed platforms, driving mechanisms and push heads 400 in a one-to-one correspondence, and a beating position for ton bags is formed between the multiple push heads 400.

[0047] In a preferred embodiment, the extension lines of the plurality of fixed platforms do not intersect, that is, the plurality of driving mechanisms and push heads 400 disposed on the fixed platforms are staggered. Figure 6 and Figure 7 The pusher heads are offset by about 5 degrees to prevent the pusher heads 400 from beating the materials in the ton bag together to form lumps. The beating of multiple pusher heads 400 can evenly distribute the force on the materials in the ton bag, reducing the probability of problems such as powder agglomeration.

[0048] To improve the load on the ton bag, the pusher head 400 features a circular arc surface facing the bag. This hemispherical design disperses the load between the bag and the arc, preventing uneven force at a single point of contact. This ensures uniform force distribution during the propulsion process, extending the life of the drive mechanism. The pusher head 400 utilizes an upward, oblique thrust mechanism to shift the center of gravity, pushing downwards on the material within the bag.

[0049] Specifically, such as Figure 7 As shown, there are three fixed platforms, three driving mechanisms and three pusher heads 400 , the tilt angle of the pusher heads 400 is 37.5°, and the three pusher heads 400 are offset by 5° from the center of the support frame 100 .

[0050] The pusher head 400 features a hollow design that effectively reduces weight, while internal reinforcement ribs significantly enhance its structural strength. This design makes the pusher head 400 both lightweight and durable, meeting the needs of efficient work.

[0051] In addition, the push head can be made of stainless steel, carbon steel or polytetrafluoroethylene. The selection of the push head material also fully considers the wear resistance, corrosion resistance and other properties to ensure long-term stability and reliability.

[0052] In a specific embodiment, the drive mechanism is a pneumatic cylinder, whose rod's extension and retraction are controlled by a time relay. The cylinder's air inlet is connected to the silo's air outlet at the feeding station via an air pipe. The cylinder's operating principle is primarily based on pneumatic transmission technology. When compressed air enters the cylinder through the inlet, it pushes the cylinder piston into linear motion. By controlling the opening and closing of the inlet and exhaust valves, the piston's direction and stroke can be precisely controlled. Furthermore, the cylinder is equipped with a buffering device to reduce the impact force when the piston reaches its extreme position, ensuring stable operation of the equipment.

[0053] Specifically, this solution uses two independent time relays to precisely control the push-out and retraction times of each cylinder. For example, the push-out time is 5 seconds and the retraction time is 35 seconds, ensuring precise and efficient operation.

[0054] In a specific embodiment, the fixed platform includes an inclined plate 310 and a baffle 320. The inclined plate 310 is fixedly connected to the support frame 100. The baffle 320 is disposed at the lower end of the inclined plate 310 and is used to support the fixed end of the drive mechanism. In particular, the fixed end of the drive mechanism and the baffle 320 can be detachably connected using bolts or snaps.

[0055] This solution also includes a pad 200 positioned beneath the support frame 100 to ensure structural stability. Pad 200 can be a short rectangular tube. There can be one or more pads 200, with multiple pads 200 positioned in the middle of each beam and at the corners of the support frame 100.

[0056] The working principle of the auxiliary unloading tooling of the feeding station is:

[0057] The ton bag is suspended in the air above the feed port of the feeding station by a crane and transported to the beating position of the support frame 100.

[0058] The support frame 100 is securely mounted on the steel platform surrounding the feeding station, ensuring the precise positioning of the drive mechanism. The drive mechanism mounted on the support frame 100 drives the pusher head 400 in linear reciprocating motion toward the ton bag. When the drive mechanism utilizes a pneumatic cylinder, precisely controlled by a time relay, it pushes the pusher head 400, which has a hemispherical contact surface, applying steady downward pressure to the ton bag, ensuring smooth and efficient material flow out of the bag.

[0059] The auxiliary unloading tooling of the feeding station provided by the utility model fully considers the physical properties of various ton bags of powder and makes adaptive improvements to the tooling structure. The beneficial effects brought by the technical solution include:

[0060] 1. Efficient automation: This tool adopts a mechanical control system, which can automatically complete the push head 400's automatic advancement and retraction, realize the auxiliary blanking process, and replace manual knocking.

[0061] 2. Precise control: This tooling adopts a precision control system, that is, a cylinder is used as the power source and precisely controlled by a time relay. The design of the push head 400 and the propulsion angle with the center of gravity of the bulk bag can make the push head with an arc surface exert a downward pressure on the bulk bag, improving the falling state and flow condition of the materials in the bulk bag, ensuring the accuracy and stability of the feeding, and through the adjustment of the time relay, the feeding speed and force can also be flexibly controlled to meet the requirements of different materials and bulk bags.

[0062] 3. Wide application range: This tooling is applicable to powders with different viscosities and particle sizes, and has strong versatility and practicability.

[0063] 4. Durability: The circular contact surface of the push head can evenly distribute the pressure, avoiding local damage to the bulk bag, and also helping to improve the feeding efficiency.

[0064] Through the above settings, the disadvantages of uneven force and insufficient design in the auxiliary feeding tooling of the existing feeding station can be solved. The tooling of this application pays more attention to versatility, durability and intelligence level, can meet the requirements of different production scenarios, and improve production efficiency and product quality.
