Description

Technical Field

[0001] This utility model relates to the field of machine tool waste conveying technology, specifically a novel chain plate chip conveyor. Background Technology

[0002] As a core piece of equipment for conveying machine tool processing waste, the chain plate chip conveyor's structural design directly affects the waste collection efficiency and equipment reliability. Existing conventional chain plate chip conveyors suffer from the following technical defects:

[0003] Height adjustment limitations:

[0004] Traditional chip conveyors have a fixed frame height, making it difficult to adapt to the chip outlet positions of different machine tools. Some improved models using hydraulic lifting have the risk of oil leakage and insufficient adjustment accuracy (the error often exceeds ±3mm), resulting in difficulties in installation and docking.

[0005] Chain plate misalignment problem:

[0006] Conveyor chains are prone to lateral shift during long-distance operation, especially when the load is uneven, the shift can reach 5-10mm, causing debris to fall and accelerating the wear of the chain and the frame.

[0007] Transmission system defects:

[0008] The single-point drive design (usually with only two drive shafts at the beginning and end) causes stress concentration in the chain at the junction of the straight and inclined sections, increasing the probability of chain breakage by more than 30% (see the literature "Research on Transmission Optimization of Machine Tool Chip Removal Equipment", 2019).

[0009] Inconvenient for movement and positioning:

[0010] Existing equipment mostly uses a fixed base or a simple roller structure, which is prone to shaking when moved and lacks an effective locking mechanism, making it prone to displacement in machine tool vibration environments.

[0011] Insufficient chip removal guidance:

[0012] Traditional chip conveyors have a vertical drop outlet design, which makes it easy for chips to accumulate on the edge of the collection box, requiring manual intervention to clean them.

[0013] In a currently disclosed technical solution for a liftable chain conveyor, the height is adjusted via a scissor-type lifting mechanism, but the following problems exist:

[0014] The lifting mechanism occupies lateral space, resulting in a 40% increase in the width of the equipment;

[0015] When a single motor drives a dual lead screw, mechanical errors cause the frame to tilt (measured tilt angle > 1°);

[0016] Without a chain plate anti-deviation structure, the failure rate of deviation is as high as 15 times per thousand hours. Utility Model Content

[0086] Chain plate hinge structure type

[0087] Standard Type I Chain Plate

[0088] Axle pin position: Located at the center of the chain plate, with symmetrical upper and lower protrusions, connected by a spherical hinge to ensure that the chain plate can rotate flexibly in the horizontal and vertical directions.

[0089] Applicable scenarios: Suitable for general chip removal scenarios, such as chip conveying and medium load environments.

[0090] Upper Flat Type II Chain Plate

[0091] Axle pin location: Located on the underside of the chain plate, with a flat upper surface and a grooved lower surface to reduce debris accumulation and improve surface flatness.

[0092] Advantages: Suitable for precision machining scenarios, such as chip removal in CNC machine tools, which can prevent chip jamming.

[0093] Connection components and transmission design

[0094] Chain and chain plate fixing method

[0095] The chain plate is fixed to the drive chain 8 by bolts or rivets, and the chain pitch must match the specifications of the chain plate (such as 31.75mm, 50.8mm, etc.).

[0096] Chain type: Mostly sleeve roller chains or plate traction chains are used to ensure high torque transmission and wear resistance.

[0097] Drive and tensioning device integration

[0098] Drive end: The motor speed is adjusted by the reducer, and the power is transmitted to the drive sprocket through the coupling, which drives the chain plate and chain to run synchronously.

[0099] Tensioning end: The chain tension is adjusted by an adjustable screw or spring mechanism to prevent slippage or chain derailment during operation.

[0100] Key structural reinforcement measures

[0101] Multi-spherical hinge design

[0102] The hinge joint of the chain plate adopts a multi-spherical contact structure to disperse stress and reduce wear, thereby improving the overall service life.

[0103] Wear-resistant and corrosion-resistant treatment

[0104] The chain plates are chrome-plated or made of stainless steel (such as 304 stainless steel) to enhance corrosion resistance; the chain undergoes carburizing and quenching treatment to improve fatigue strength.

[0105] Assembly process key points

[0106] Pre-installation inspection: Confirm that the chain plate and chain specifications match, and check the integrity of accessories such as pins and rollers.

[0107] Chain tension adjustment: After installation, the chain tension needs to be manually tested to ensure that there is no obvious sagging or excessive tightness during operation.

[0108] Linkage test: Observe whether the movement trajectory of the chain plate is smooth during no-load trial operation, and focus on checking for abnormal noises or jamming.

[0109] Detailed Workflow

[0110] Preparation

[0111] Check that all components are working properly, especially the condition of the chain plate frame 2, transmission device, drive device and screw lifting device.

[0112] Confirm that the universal pulleys 15 on the lifting frame 1 are locked to ensure that the equipment is stable and does not move.

[0113] Start the device

[0114] Turn on the drive motor 6, which drives the drive shaft 16 at the tail end of the chain plate frame 2 to rotate through the transmission chain 8 and the transmission sprocket 7, thereby driving the entire conveyor chain plate 5 system to start cyclical movement.

[0115] According to actual needs, start the lifting motor 12 and adjust the height of the chain plate frame 2 through the screw lifting device to ensure that it is properly connected with the chip discharge port of the machine tool.

[0116] chip removal operation

[0117] The chips fall from the chip discharge port of the machine tool into the inlet end of the conveyor chain plate 5. As the conveyor chain plate 5 circulates, the chips are gradually transported to the inclined section of the chain plate frame 2.

[0118] At the end of the inclined section, the chips slide down through the guide frame 18 into the designated collection container.

[0119] Cleaning and maintenance

[0120] After the equipment has been running for a period of time, regularly check and clean the residual chips on the surface of the conveyor chain plate 5 to prevent blockage or affect subsequent operations.

[0121] Regularly check the working condition of the screw jack and add lubricating oil as needed to ensure its smooth operation.

[0122] Shutdown Inspection

[0123] After completing the chip removal task, turn off the drive motor 6 and the lifting motor 12, and perform necessary inspections and maintenance.

[0124] Release the locking state of the universal pulley 15. If you need to move the device, you can push it to the appropriate position using the universal pulley 15.
