Description

Technical Field

[0001] This utility model relates to the field of centrifuge basket unloading equipment, specifically a centrifuge basket unloading equipment integrated with a non-powered conveyor belt. Background Technology

[0002] Powder zinc diffusion technology utilizes solid-state diffusion at high temperatures of 380°C-420°C to allow zinc and iron atoms to interpenetrate and form a gradient-transition alloy. The zinc layer exhibits extremely strong adhesion to the substrate and high microhardness, effectively resisting friction and scratches. To further enhance corrosion resistance, a passivation process is required after zinc diffusion to generate a micron- or even nano-scale inorganic passivation film. This passivation film temporarily isolates corrosive media and delays the formation of white rust on the zinc layer, playing a crucial role in protecting the underlying zinc layer. However, the passivation film is extremely thin and brittle, unable to withstand severe impacts or scratches. Localized damage can lead to a decrease in corrosion resistance. Therefore, it is essential to carefully avoid impacts to the product in all stages after the passivation process.

[0003] For small fasteners such as nuts and washers, a centrifugal drying process is often used after zinc passivation, and the products in the centrifuge basket need to be transferred to the next process. Since the loading capacity of a single centrifuge basket in mass production is over 100 kg, it is difficult to manually handle and dump them, and traditional unloading methods are prone to causing products to roll, bump, and damage the passivation film.

[0004] The existing centrifuge basket unloading method has core technical shortcomings, which seriously affect product quality and production efficiency: manual unloading is labor-intensive and has poor adaptability: the weight of a single centrifuge basket and product exceeds 100kg, making manual handling and tilting difficult, and it is impossible to accurately adjust the unloading angle according to the product loading situation. The product is prone to rolling and bumping due to excessive tilting speed, which damages the passivation film and affects the anti-corrosion performance. Utility Model Content

[0005] The purpose of this invention is to provide a non-powered conveyor belt integrated centrifugal basket unloading device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a non-powered conveyor belt integrated centrifugal basket unloading device, including a support frame, a non-powered roller conveyor belt on the support frame, an unloading mechanism at one end of the non-powered roller conveyor belt, and a lever locking mechanism at the end of the non-powered roller conveyor belt away from the unloading mechanism.

[0007] In a preferred embodiment of this utility model, the unloading mechanism includes a carrying conveyor belt, which is connected to the conveying end face of a non-powered roller conveyor belt. A rotating unloading component is provided at the bottom of the carrying conveyor belt near the end of the non-powered roller conveyor belt. A steering connector is provided at the end of the support frame near the carrying conveyor belt. The rotating unloading component is hinged to the steering connector via an unloading rotating shaft. A centrifugal basket guardrail is provided on the carrying conveyor belt, and a lever is provided on one side of the centrifugal basket guardrail.

[0008] In a preferred embodiment of this invention, the lever is connected to the centrifugal basket guardrail via several connecting rods, and a lifting lug is provided at the bottom of the other end of the lever, with a counterweight hanging on the lifting lug.

[0009] As a preferred embodiment of this utility model, the lever locking mechanism includes a fixed connecting rod and a locking rod. The fixed connecting rod is mounted on a support frame away from the rotating unloading component. One end of the locking rod is mounted on the fixed connecting rod via a mounting pin. The other end of the locking rod is provided with a locking pin. A locking groove is provided on the lever corresponding to the position of the locking pin. The locking pin is adapted to the locking groove.

[0010] As a preferred embodiment of this utility model, an unloading positioning block is provided below the rotating unloading component corresponding to the carrying conveyor belt. The unloading positioning block is assembled on the support frame by mounting pin 2. When the carrying conveyor belt rotates along the unloading rotation axis, the unloading positioning block abuts against the bottom of the carrying conveyor belt.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1. With the design of the carrying conveyor belt rotating and tilting around the unloading axis, and the detachable and adjustable unloading positioning block, the unloading angle can be precisely adjusted according to the product loading situation; the centrifugal basket tilts smoothly with the carrying conveyor belt, and the internal products slide out slowly, avoiding the rapid rolling and collision caused by traditional manual dumping; 2. Through the coordinated design of levers and counterweights, and with the assistance of the counterweight torque, operators only need to lightly lift and press the levers to drive the conveyor belt to rotate, without the need to move the centrifuge baskets and products; this greatly reduces the difficulty and labor intensity of manual operation and solves the problem of laborious unloading in traditional manual methods. 3. By matching the locking pin of the lever locking mechanism with the lever locking groove, the lever and the carrying conveyor belt can be fixed in the non-unloaded state, so as to keep them in a horizontal conveying state; to prevent the centrifuge basket from slipping due to accidental tilting of the equipment, to ensure the stability of the conveying and standby processes, and to avoid safety risks.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 5 This utility model provides a technical solution: A centrifugal basket unloading device with a non-powered conveyor belt includes a support frame 1, a non-powered roller conveyor belt 2 on the support frame 1, an unloading mechanism 3 at one end of the non-powered roller conveyor belt 2, and a lever locking mechanism 4 at the end of the non-powered roller conveyor belt 2 away from the unloading mechanism 3. The lever locking mechanism 4 can lock the state of the unloading mechanism 3. The unloading mechanism 3 includes a carrying conveyor belt 301, which is connected to the conveying end face of the non-powered roller conveyor belt 2. A rotating unloading component 302 is provided at the bottom of the carrying conveyor belt 301 near the non-powered roller conveyor belt 2. A steering connector 303 is provided at the end of the support frame 1 near the carrying conveyor belt 301. The rotating unloading component 302 is hinged to the steering connector 303 through an unloading rotating shaft 304, so that the carrying conveyor belt 301 can rotate and tilt around the unloading rotating shaft 304. A centrifugal basket guardrail 305 is provided on the carrying conveyor belt 301. The centrifugal basket guardrail 305 is used to limit the centrifugal basket and prevent it from slipping during the conveying process. A lever 306 is provided on one side of the centrifugal basket guardrail 305. The lever 306 is connected to the centrifugal basket guardrail 305 via several connecting rods 306-1. The bottom of the other end of the lever 306 is provided with a lifting lug 306-2, and a counterweight 306-3 is hung on the lifting lug 306-2. The counterweight 306-3 can adjust the torque of the lever 306 to assist in the completion of the unloading action. The lever locking mechanism 4 includes a fixed connecting rod 401 and a locking rod 402. The fixed connecting rod 401 is mounted on the support frame 1 away from the rotating unloading component 302. One end of the locking rod 402 is mounted on the fixed connecting rod 401 by a mounting pin 403. The other end of the locking rod 402 is provided with a locking pin 404. A locking groove 404-1 is provided on the lever 306 at the position corresponding to the locking pin 404. The locking pin 404 is adapted to the locking groove 404-1. When the locking pin 404 is inserted into the locking groove 404-1, the lever 306 can be fixed, thus restricting the rotation of the unloading mechanism 3. An unloading positioning block 5 is provided below the rotating unloading component 302 and corresponding to the carrying conveyor belt 301. The unloading positioning block 5 is assembled on the support frame 1 by mounting pin 2 501. Mounting pin 2 501 facilitates the disassembly, assembly and position adjustment of the unloading positioning block 5. When the carrying conveyor belt 301 rotates along the unloading rotation axis 304, the unloading positioning block 5 abuts against the bottom of the carrying conveyor belt 301. The unloading positioning block 5 is used to support the tilted carrying conveyor belt 301, limit its tilt angle and ensure the stable operation of the unloading.

[0016] The principle and usage process of this utility model: Based on the weight of the centrifuge basket 6 to be unloaded and the characteristics of the internal zinc-infiltrated powder products such as nuts and washers, select a counterweight block 306-3 of appropriate weight and hang it on the lifting lug 306-2 of the lever 306. Adjust the torque of the lever 306 to ensure that unloading is effortless and the operation is smooth.

[0017] The production and transportation process is initiated by placing the centrifuge basket 6, which has undergone passivation treatment and is loaded with zinc powder, smoothly onto the non-powered roller conveyor belt 2. Relying on manual pushing and conveying inertia, the centrifuge basket 6 moves along the non-powered roller conveyor belt 2 towards the unloading mechanism 3. After the centrifuge basket 6 enters the carrying conveyor belt 301, the centrifuge basket guardrail 305 limits the centrifuge basket 6 on both sides to prevent it from slipping or deviating during transportation, ensuring that the centrifuge basket 6 accurately stops at the preset unloading position of the carrying conveyor belt 301.

[0018] Based on the loading volume and particle size of the products in the centrifuge basket 6, determine the appropriate unloading tilt angle. If the angle needs to be adjusted, first pull out the second mounting pin 501, move the unloading positioning block 5 on the support frame 1 to the mounting position, adjust it to the support point corresponding to the target angle, and then reinsert the second mounting pin 501 to fix the unloading positioning block 5. Then, pull out the locking pin 404 of the lever locking mechanism 4, rotate the locking rod 402 along the first mounting pin 403 to avoid the unlocking lever 306, release the fixing restriction on the lever 306, and prepare to start the unloading action.

[0019] The operator holds the end of lever 306 and, with the assistance of the counterweight 306-3, slowly lifts lever 306. This causes the centrifuge basket guardrail 305 and the carrying conveyor belt 301 to rotate and tilt around the unloading rotation axis 304 via connecting rod 306-1. When the bottom of the carrying conveyor belt 301 is in close contact with the unloading positioning block 5, the carrying conveyor belt 301 maintains a stable tilt, and the lifting of lever 306 stops. At this time, the centrifuge basket 6 tilts with the carrying conveyor belt 301, and the powder zinc-impregnated product inside slowly slides out along the inner wall of the centrifuge basket 6. The operator aligns the carrying container, such as a turnover box, with the discharge port of the centrifuge basket 6 to receive the product, avoiding direct impact or rolling of the product that could damage the passivation film.

[0020] After the product in the centrifuge basket 6 has been completely transferred to the carrying container, the operator slowly presses down on the lever 306, causing the carrying conveyor belt 301 to rotate in the opposite direction and reset until the carrying conveyor belt 301 and the unpowered roller conveyor belt 2 are level. The lever 306 is then reset to its initial position, and the locking rod 402 is rotated along the mounting pin 403 to lock the lever 306. The locking pin 404 is inserted to match the locking groove 404-1, and the lever 306 is fixed by the lever locking mechanism 4, restricting the rotation of the unloading mechanism 3. The empty centrifuge basket 6 is then removed, placed on the unpowered roller conveyor belt 2, and pushed to the next process. If it is necessary to continue unloading the next batch of products, the previous steps can be repeated. After the operation is completed, the remaining product debris on the surface of the equipment is cleaned, and the connection status of each component is checked to ensure that the equipment is stable in standby mode.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
