Description

Technical Field

[0001] The present invention relates to the field of chip conveyors, in particular to a scraper assembly for a chip conveyor. Background Art

[0002] A scraper is a common structure used to transport and transfer metal chips in a chip conveyor. It is commonly used in general machine tool chip removal products and negative pressure filtration centralized processing systems. In a chip conveyor, the chain is mainly driven by a motor to move, and the scraper is fixed on the chain. When the chain is running, it will drag the metal chips that have fallen on the bottom of the chip conveyor and accumulated on the chain, and transport the chips to the head of the chip conveyor and drop them into the chip collection bucket. The scraper currently used in chip conveyors, when the scraper moves forward to remove chips, usually leaves some chips at the bottom of the scraper. When the scraper moves forward, this part of the chips will lift the scraper, causing the scraper to be stuck in the chain and unable to swing freely, so that the scraper always maintains a posture, which may wear the chip conveyor or even damage the scraper. Summary of the Invention

[0003] Based on this, it is necessary to provide a scraper assembly for a chip conveyor to address the problem in the prior art that the scraper is lifted up by the debris underneath, causing the scraper to get stuck in the chain and the scraper posture cannot be adjusted. The relative posture of the scraper and the chain of the scraper assembly can be adjusted to prevent the scraper from getting stuck in the chain and wearing out the chip conveyor when it cannot swing.

[0004] A scraper assembly for a chip conveyor, the scraper assembly comprising a scraper and a connecting plate connecting the scraper to the chain of the chip conveyor; the connecting plates are provided at both ends of the scraper, the first end of the connecting plate is inserted into the mounting hole on the chain, and the first end is loosely fitted with the mounting hole; an adjustment block is provided on the upper end surface of the connecting plate; the adjustment block comprises a magnetic column and an electromagnet, and when the electromagnet is energized, the magnetic column moves in a direction away from the electromagnet to adjust the posture of the scraper.

[0005] Furthermore, the adjustment block is provided with two holes, an electromagnet is provided at one end of the hole, a magnetic column is provided in the hole, and the S pole of the magnetic column is close to the S pole of the electromagnet.

[0006] Furthermore, a battery is provided in the regulating block, and the battery is located between the two holes, and the electromagnet is powered by the battery.

[0007] Furthermore, at least two distance sensors are provided on one side surface of the adjustment block, and the distance sensors are used to detect the distance between one side surface of the adjustment block and the inner side surface of the mounting hole.

[0008] Furthermore, level sensors are respectively provided on two opposite side surfaces of the adjustment block, and the level sensors are used to detect the angle of the connecting plate in the mounting hole.

[0011] The present invention provides a scraper assembly for a chip conveyor, wherein an adjustment block is provided on a connecting plate of the scraper assembly, and an electromagnet and a magnetic column are provided on the adjustment block. The electromagnet and the magnetic column repel each other when energized. When the scraper and the chain are stuck together, that is, when the scraper cannot swing freely during forward movement, the electromagnet is energized, and the electromagnet and the magnetic column repel each other, and the magnetic column moves away from the electromagnet. The impact force during movement releases the scraper and the chain from the state of being stuck together, thereby allowing the scraper to swing freely within the mounting hole of the chain. That is, the scraper assembly provided by the present invention adjusts the movement posture of the scraper through the adjustment block, thereby preventing the scraper and the chain from getting stuck together and damaging the chip conveyor.

[0015] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0016] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an element centered thereon. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an element centered thereon. The terms "vertical," "horizontal," "left," "right," "top," "bottom," "bottom end," "top end," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] In one embodiment, a scraper assembly for a chip conveyor of the present invention includes a scraper and a connecting plate connecting the scraper to the chip conveyor chain; connecting plates are provided at both ends of the scraper, the first end of the connecting plate is inserted into the mounting hole on the chain, and the first end is gap-fitted with the mounting hole; an adjustment block is provided on the upper end surface of the connecting plate; the adjustment block includes a magnetic column and an electromagnet, and when the electromagnet is energized, the magnetic column moves in a direction away from the electromagnet to adjust the posture of the scraper.

[0019] In the present invention, an adjustment block is provided on the connecting plate of the scraper assembly. The adjustment block is provided with a magnetic column and an electromagnet, and the south pole of the magnetic column and the south pole of the electromagnet are close to each other. When the scraper assembly is in normal motion, the electromagnet is not energized, the magnetic column and the electromagnet are attracted to each other, and the first end of the connecting plate can swing freely within the mounting hole, thereby making the scraper scrape and move more smoothly at the rotation point. However, when there is debris on the bottom of the scraper, the debris may lift the scraper, causing the first end of the connecting plate to be stuck in the mounting hole. At this time, the first end is in a fixed state in the mounting hole, that is, the scraper cannot swing freely and cannot adjust its posture according to the motion state. At this time, when the electromagnet is energized, the south pole of the electromagnet repels the south pole of the magnetic column, causing the magnetic column to move in a direction away from the electromagnet. The impact force generated during the movement of the magnetic column releases the first end from being stuck in the mounting hole, allowing the scraper to swing freely, that is, the scraper can adjust its posture at any time according to the motion state.

[0020] The scraper assembly for a chip conveyor will be described below in conjunction with specific embodiments to further understand the inventive concept of the scraper assembly for a chip conveyor.

[0021] In one embodiment, if Figure 1-2As shown, a scraper assembly for a chip conveyor includes a scraper 1 and a connecting plate 2 for connecting the scraper 1 to the chip conveyor chain 3; specifically, connecting plates 2 are provided at both ends of the scraper 1, the first end 21 of the connecting plate 2 is inserted into the mounting hole 31 on the chain 3, and the width of the first end 21 is smaller than the width of the connecting plate 2, and the first end 21 is clearance-matched with the mounting hole 31. Preferably, the mounting hole 31 is a waist-shaped hole to ensure that the first end 21 can swing freely in the mounting hole 31 during normal operation of the scraper assembly; wherein, an adjusting block 4 is provided at the upper end of the connecting plate 2 to adjust Block 4 includes a magnetic column 42 and an electromagnet 43. When the electromagnet 43 is energized, the magnetic column 42 can move in a direction away from the electromagnet 43 to adjust the posture of the scraper. Specifically, when the debris under the scraper 1 pushes up the scraper, the first end 21 is stuck in the mounting hole 31, that is, the first end 21 can no longer swing freely in the mounting hole 31. At this time, the electromagnet 43 is energized, and the magnetic column 42 will move in a direction away from the electromagnet 43. An impact force will be generated during the operation and the impact force will act on the side wall of the mounting hole 31, thereby releasing the stuck state of the first end in the mounting hole 31.

[0022] In another embodiment, if Figure 2-3 As shown, two holes 41 are provided on the adjustment block 4, and an electromagnet 43 is provided at one end of the hole 41, and the electromagnet 43 is located on the side close to the connecting plate 2, and the side of the electromagnet 43 close to the connecting plate 2 is flush with the adjustment block 4, and the end of the electromagnet 43 facing away from the connecting plate 2 is the S pole. A magnetic column 42 is provided in the hole 41, and the magnetic column 42 is a permanent magnet. The end of the magnetic column 42 close to the electromagnet 43 is the S pole, and the end of the magnetic column 42 away from the electromagnet 43 faces the inner side of the mounting hole 31. When electromagnet 41 is de-energized, magnetic column 42 and electromagnet 43 attract each other, with the south pole of magnetic column 42 abutting against electromagnet 43 and the north pole of magnetic column 42 flush with the end face of adjustment block 4. When electromagnet 43 is energized, the south pole of electromagnet 43 and the south pole of magnetic column 42 repel each other, causing magnetic column 42 to move away from electromagnet 43. When magnetic column 42 contacts the inner side of mounting hole 31, it exerts a force on mounting hole 31, thereby releasing the stuck state between first end 21 and mounting hole 31. Adjustment block 4 also includes a battery 44, located between the two holes 41. Battery 44 is electrically connected to the two electromagnets 43, and power is supplied to the electromagnets 43 via battery 44.

[0023] In another embodiment, if Figure 2As shown, at least two distance sensors 45 are provided on one side of the adjustment block 4, and the distance sensor 45 is used to detect the distance between one side of the adjustment block 4 and the inner side of the mounting hole 31. When the scraper assembly is moving normally, that is, the first end 21 can swing freely in the mounting hole 31, and the distance detected by the distance sensor 45 changes all the time. When the scraper 1 is lifted up by debris, the first end 21 may be stuck in the mounting hole 31, resulting in the first end 21 being unable to swing freely in the mounting hole 31. The distance detected by the distance sensor is a fixed value. At this time, it is necessary to energize the electromagnet 43 so that the electromagnet 43 and the magnetic column 42 repel each other, generating an impact force to contact the stuck state of the first end 21 in the mounting hole 31, so that the scraper 1 can swing freely during the forward movement and adjust its posture at any time.

[0024] In another embodiment, if Figure 2 As shown, a horizontal sensor 46 is respectively provided on two opposite sides of the adjustment block 4, and the horizontal sensor 46 is used to detect the angle of the connecting plate 2 in the mounting hole 31. Specifically, when the scraper assembly is moving normally, that is, the first end 21 can swing freely in the mounting hole 31, and the angle detected by the horizontal sensor 46 changes all the time. When the scraper 1 is lifted up by debris, the first end 21 may be stuck in the mounting hole 31, resulting in the first end 21 being unable to swing freely in the mounting hole 31. The angle detected by the horizontal sensor 46 is a fixed value. At this time, it is necessary to energize the electromagnet 43 so that the electromagnet 43 and the magnetic column 42 repel each other, generate an impact force to contact the stuck state of the first end 21 in the mounting hole 31, so that the scraper 1 can swing freely during the forward movement and adjust its posture at any time.
