Description

[0056] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a chip conveyor, which includes a chip conveyor body 1, a shearing structure 20, a stopper 30, a contact detection member and a control member. The chip conveyor body 1 includes a conveying portion 11 for conveying chips. The shearing structure 20 is arranged on the conveying portion 11, and the shearing structure 20 includes a first shearing portion 21 and a second shearing portion 22. The first shearing portion 21 and the second shearing portion 22 can be movably arranged to move to a shearing position where the blade of the first shearing portion 21 and the blade of the second shearing portion 22 are in contact or a separation position where the first shearing portion 21 and the second shearing portion 22 are separated. The stopper 30 is arranged on the conveying portion 11 and is located on the side of the shearing structure 20 away from the entrance of the conveying portion 11. The stopper 30 and the conveying surface of the conveying portion 11 form a stopper opening 34. The detection end of the contact detection member is arranged at the outer edge of the stopper opening 34, and the contact detection member is used to detect the contact between the outer edge of the stopper opening 34 and the chips. The contact detection member and the shearing structure 20 are both connected to the control member so as to control the shearing structure 20 to move to the shearing position or the separation position according to the detection result of the contact detection member.

[0058] The chip conveyor provided by the first embodiment of the present invention can first optimize the size control of the chip body. The limit opening 34 formed by the limit member 30 and the conveying surface, and the contact detection member arranged on the outer edge of the limit opening 34 can dynamically monitor the size of the chip body and adjust the position of the shearing structure 20 in time. This size control mechanism ensures that the size of the chip body will not be larger than the size of the limit opening 34 during the chip removal process, thereby avoiding the blockage of the limit opening 34. Secondly, by arranging a movable first shearing part 21 and a second shearing part 22 on the chip conveyor body 1, it can automatically identify and process large-sized chips and cut them into smaller chips, thereby avoiding the chips from entangled or blocking the chip removal port during the chip removal process, and significantly improving the chip removal efficiency and continuous operation capacity of the chip conveyor. The connection between the control member, the contact detection member and the shearing structure 20 realizes the automatic control of the chip size detection and the shearing action. There is no need for manual regular replacement and cleaning, which greatly reduces the need for manual intervention, improves the level of production automation, and saves labor costs. In addition, the combined design of the stopper 30 and the shearing structure 20 can adapt to chips of different sizes and types, including metal chips, plastic chips, etc., thereby improving the versatility and adaptability of the chip conveyor and making it suitable for a variety of processing environments and materials. Therefore, the chip conveyor provided in this embodiment can solve the technical problem in the prior art that the chip conveyor outlet is easily blocked when the chip mass is too large.

[0059] Specifically, when the contact detection member detects that the outer edge of the limit opening 34 is in contact with the chip, the shearing structure 20 is controlled to move to the shearing position; when the contact detection member detects that the outer edge of the limit opening 34 is not in contact with the chip, the shearing structure 20 is controlled to move to the separation position. In this way, the contact state between the chip and the outer edge of the limit opening 34 is monitored in real time by the contact detection member, and accurate chip size control is achieved. When it is detected that the chip is in contact with the outer edge of the limit opening 34, it means that the chip size is larger than the limit opening 34, and the shearing structure 20 automatically moves to the shearing position for shearing, avoiding blockage and chip jamming caused by excessively large chips, and ensuring smooth operation and efficient chip removal of the chip conveyor. When the chip does not contact the outer edge of the limit opening 34, it means that the chip size is smaller than the limit opening 34, and the shearing structure 20 moves to the separation position, avoiding unnecessary shearing actions, saving energy and reducing mechanical wear.

[0060] Specifically, the conveying part 11 is a chain plate structure.

[0061] Specifically, the chip conveyor also includes a driving structure 40, the driving end of the driving structure 40 is movably arranged, and the first shearing part 21 and the second shearing part 22 are both drivingly connected to the driving end of the driving structure 40. Among them, the control member is connected to the driving structure 40 to control the activity of the driving end of the driving structure 40 according to the detection result of the contact detection member. With such a structural setting, the integrated design of the driving structure 40 and the shearing structure 20, as well as the connection with the control member, realizes the automation and precise control of the shearing action. The driving structure 40 connected to the control member can respond to the signal of the contact detection member and quickly adjust the position of the shearing structure 20, thereby improving the response speed and shearing efficiency of the equipment.

[0062] Specifically, the driving structure 40 is a cylinder, and the driving end of the driving structure 40 can be raised and lowered. In this way, the cylinder as a driving structure can provide stable and powerful power to ensure the accurate movement of the shearing structure 20 between the shearing position and the separation position. At the same time, the position of the shearing structure 20 is controlled by raising and lowering the driving end, which makes the operation simpler and more efficient, and facilitates the maintenance and adjustment of the shearing structure 20, ensuring the shearing efficiency and shearing quality.

[0063] Specifically, when the contact detection member detects that the outer edge of the limit opening 34 is in contact with the chip, the driving end of the driving structure 40 is controlled to move upward; when the contact detection member detects that the outer edge of the limit opening 34 is not in contact with the chip, the driving end of the driving structure 40 is controlled to move downward. In this way, the chip contact detection is combined with the lifting and lowering movement driven by the cylinder to realize the intelligent control of the shearing structure 20. When the chip contacts the outer edge of the limit opening 34, the cylinder driving end moves upward to ensure that the shearing structure 20 is in the shearing position and the shearing process is carried out in time; when the chip does not contact the outer edge of the limit opening 34, the driving end moves downward and the shearing structure 20 is in the separation position, avoiding empty shearing or excessive shearing, and improving the energy efficiency ratio and operational safety of the equipment. This dynamic control method based on contact detection ensures that the chip conveyor can handle the chips more accurately and flexibly.

[0064] Specifically, the chip conveyor further comprises a linkage structure 50, which is arranged on one side of the shearing structure 20. The linkage structure 50 comprises a sliding track 51, a first sliding member 52 and a second sliding member 53. The first sliding member 52 and the second sliding member 53 are both arranged in the sliding track 51, the first sliding member 52 is connected to the first shearing part 21, and the second sliding member 53 is connected to the second shearing part 22. Among them, one of the first sliding member 52 and the second sliding member 53 is movably arranged in a direction close to or away from the other. With such a structural arrangement, by arranging the linkage structure 50 on one side of the shearing structure 20, accurate control and stable movement of the shearing part are achieved. The first sliding member 52 and the second sliding member 53 are respectively connected to the first shearing part 21 and the second shearing part 22, so that the two shearing parts can move smoothly along the sliding track 51, thereby improving the stability and efficiency of the shearing action. The design of this linkage structure 50 ensures the accurate alignment of the two shearing parts, reduces the deviation in the shearing process, and thus improves the precision and reliability of shearing.

[0065] Specifically, the first sliding member 52 and the second sliding member 53 are both roller structures. In this way, the sliding member with the roller structure moves in the sliding track 51, which reduces friction, improves the smoothness and speed of movement of the two shearing parts, reduces power requirements, and also reduces mechanical wear and prolongs the service life of the equipment. The design of the roller structure also facilitates the rapid positioning of the shearing part, reduces the time required for adjusting the shearing part, and improves production efficiency.

[0066] Specifically, the first sliding member 52 and the second sliding member 53 are both rubber pulleys.

[0067] Specifically, the sliding track 51 is a linear track.

[0068] In this embodiment, the chip conveyor further includes a driving structure 40, the driving end of the driving structure 40 is movably arranged, and the chip conveyor further includes a first linkage rod 61 and a second linkage rod 62, one end of the first linkage rod 61 and one end of the second linkage rod 62 are hinged, the other end of the first linkage rod 61 is connected to the first sliding member 52, and the other end of the second linkage rod 62 is connected to the second sliding member 53. With such a structural setting, the integrated application of the driving structure 40 and the linkage rod realizes the automatic control and efficient driving of the shearing structure 20. The driving end of the driving structure 40 is hinged to one end of the first linkage rod 61 and the second linkage rod 62, and power can be transmitted through the linkage rod, so that the first sliding member 52 and the second sliding member 53 move along the sliding track 51, thereby controlling the shearing action of the two shearing parts. This integrated control method reduces the complexity of the equipment, improves the response speed and shearing efficiency of the drive, and also simplifies the maintenance process.

[0069] Specifically, the length of the first linkage rod 61 in the extension direction of the first linkage rod 61 is equal to the length of the second linkage rod 62 in the extension direction of the second linkage rod 62. In this way, it is ensured that the two shearing parts can maintain symmetry when moving, avoiding possible deflection during the shearing process, and further improving the precision and effect of shearing.

[0070] Specifically, one end of the first linkage rod 61 and one end of the second linkage rod 62 are both connected to the driving end of the driving structure 40. In this way, the linkage rod is directly connected to the driving end of the driving structure 40, which reduces the energy loss in the power transmission process, improves the power transmission efficiency, and ensures the stable operation of the shearing structure 20 and the accurate transmission of the shearing force.

[0071] Specifically, the chip conveyor further includes a first buffer 71 and a second buffer 72, wherein the first buffer 71 is arranged at one end of the sliding track 51, and the second buffer 72 is arranged at the other end of the sliding track 51, and the side of the first buffer 71 close to the first sliding member 52 is used to abut against the first sliding member 52, and the side of the second buffer 72 close to the second sliding member 53 is used to abut against the second sliding member 53. With such a structural arrangement, by arranging the first buffer 71 and the second buffer 72, the impact force of the first sliding member 52 and the second sliding member 53 when moving to the two ends of the track is effectively absorbed, thereby avoiding damage to mechanical parts or position displacement of the shearing structure 20 caused by impact, and improving the stability and durability of the equipment. At the same time, the use of the buffer ensures that the shearing part can stop smoothly when reaching the preset position, reduces noise, and improves the working environment.

[0072] Specifically, the first buffer 71 and the second buffer 72 are both urethane anti-collision blocks. As such, the urethane anti-collision blocks, as buffers, can effectively reduce the vibration and noise when the sliding part collides with the end of the track due to their good elasticity and energy absorption characteristics, and protect the sliding part and the track from impact damage.

[0073] In this embodiment, the conveying section 11 includes a first conveying section 111 and a second conveying section 112 connected to each other, wherein the first conveying section 111 is inclined and the second conveying section 112 is horizontally arranged. The stopper 30 and the shearing structure 20 are both arranged at the connection between the first conveying section 111 and the second conveying section 112; at least part of the first shearing section 21 is attached to the stopper 30, and at least part of the second shearing section 22 is attached to the stopper 30; the first shearing section 21 and the second shearing section 22 are both movably arranged along the extension direction of the stopper 30. With such a structural arrangement, the inclined arrangement of the first conveying section 111 and the horizontal arrangement of the second conveying section 112, combined with the arrangement of the stopper 30 and the shearing structure 20, optimize the conveying path and shearing timing of the chips. The inclined section is conducive to the natural sliding of the chips, while the horizontal section provides a stable platform for the shearing operation. This design ensures smooth conveying of chips and effective processing of chips by the shearing structure 20, reduces accumulation and jamming of chips during conveying, and improves the processing capacity and efficiency of the chip conveyor.

[0074] Specifically, an end of the first conveying section 111 away from the second conveying section 112 is located above an end of the first conveying section 111 close to the second conveying section 112 .

[0075] Specifically, the chip conveyor also includes a cleaning brush, which is attached to the side of the limiter 30 close to the shearing structure 20, and the side of the cleaning brush away from the limiter 30 is used for frictional contact with the first shearing part 21 and the second shearing part 22. With such a structural arrangement, the cleaning brush is attached to the side of the limiter 30 close to the shearing structure 20, and can be in frictional contact with the first shearing part 21 and the second shearing part 22, effectively removing residual chips or coolant on the surface of the shearing part, keeping the shearing part clean, and avoiding the problem of reduced shearing quality or further jamming caused by residual chips. The use of the cleaning brush reduces the need for manual cleaning, improves the level of automation, and at the same time extends the service life of the shearing part, reduces maintenance costs, and maintains the long-term stable operation of the chip conveyor.

[0076] In this embodiment, the limiting member 30 includes a first limiting segment 31, a second limiting segment 32 and a third limiting segment 33 connected in sequence, the first limiting segment 31 and the third limiting segment 33 are arranged opposite to each other, and the limiting opening 34 is located between the first limiting segment 31 and the third limiting segment 33. Among them, one of the first limiting segment 31 and the third limiting segment 33 is movably arranged in a direction close to or away from the other, and the first limiting segment 31 and the third limiting segment 33 are both connected to the control member to control the movement of the first limiting segment 31 and the third limiting segment 33 according to the detection result of the contact detection member. With such a structural setting, this multi-stage limiting member 30 design enables the width of the limiting opening 34 to be dynamically adjusted according to the size of the chip body, thereby improving the adaptability of the chip conveyor to chips of different sizes, so that the size of the limiting opening 34 can be adjusted accordingly according to the needs of different chip conveyors, thereby facilitating the control of the size of the chip body.

[0077] Specifically, the chip conveyor also includes a visual detection device, which is arranged on one side of the entrance of the conveying part 11. The visual detection device is used to detect the length of the chips in the extension direction of the conveying part 11. The control part is connected to the visual detection device to control the movement frequency of the shearing structure 20 according to the detection result of the visual detection device. With such a structural setting, the addition of the visual detection device enables the chip conveyor to automatically detect the length of the chips in the conveying direction, and then intelligently adjust the movement frequency of the shearing structure 20 according to the actual size of the chips. This control mechanism based on visual detection improves the accuracy and efficiency of shearing, avoids excessive shearing of short chips or insufficient shearing of long chips, ensures the consistency of chip size, and improves the convenience and efficiency of subsequent processing.

[0078] Specifically, a control valve is provided on the driving structure 40, and the control valve is connected to the driving end of the driving structure 40, and the control valve is used to control the operating frequency of the driving end of the driving structure 40. Specifically, the control valve is a solenoid valve, and the opening of the solenoid valve is adjustable to adjust the inlet and outlet of the gas in the cylinder.

[0079] Specifically, the chip conveyor also includes a chip pusher, which is arranged on the side of the shearing structure 20 away from the limiting member 30, and the chip pusher end of the chip pusher is movably arranged in a direction close to or away from the limiting opening 34. The chip pusher end of the chip pusher is used to push the chips. Specifically, when the contact detection member detects that the outer edge of the limiting opening 34 is in contact with the chips, the shearing structure 20 is controlled to move to the shearing position and the chip pusher moves in a direction close to the limiting opening 34; when the contact detection member detects that the outer edge of the limiting opening 34 is not in contact with the chips, the shearing structure 20 is controlled to move to the separation position and the chip pusher avoids the chips. Specifically, the chip pusher end of the chip pusher is a chip pusher plate, and the extension direction of the chip pusher plate is perpendicular to the extension direction of the first conveying section 111. In this way, the conveying of chips can be assisted, especially when processing large-volume chips or chip clusters. When the contact detection member detects that the chip body contacts the limit opening 34, the shearing structure 20 moves to the shearing position, and at the same time, the chip pusher moves toward the limit opening 34 to push the chip body through the limit opening 34, ensuring stable transportation and accurate shearing of the chip body. When the chip body does not contact the limit opening 34, the chip pusher avoids the chip body, avoiding interference with the normal transportation of the chip body and maintaining the smoothness of the transportation process. The coordinated action of the chip pusher and the shearing structure 20 improves the chip handling capacity and flexibility of the chip conveyor, reduces the risk of chip accumulation and jamming during transportation, and ensures a continuous chip removal process.

[0080] In this embodiment, the chip conveyor further comprises a mounting member 80, which is detachably arranged on the chip conveyor body 1, and the driving structure 40 is mounted on the mounting member 80 and is located above the limiting member 30. Specifically, the mounting member 80 is a triangular structure. In this way, the stability and correct alignment of the driving structure 40 during operation are ensured.

[0081] Specifically, in order to improve safety, the chip conveyor also includes a chip guard sheet metal, which is arranged on the side of the shearing structure 20. There are two chip guard sheets, which are respectively located on both sides of the shearing structure 20, and the chip guard sheets are used to shield the splashed chips. Safety gratings are installed on both sides of the shearing structure 20 to identify the approach of people. When the safety grating detects that someone is approaching, the shearing structure 20 stops running, thereby effectively preventing people from being injured accidentally after approaching.

[0082] Specifically, the shearing structure 20 is detachably arranged, and the first shearing portion 21 and the second shearing portion 22 need to be cleaned with anti-rust oil.

[0083] A second embodiment of the present invention provides a machine tool, which includes the chip conveyor provided in the first embodiment.

[0084] The machine tool provided by the second embodiment of the present invention can first optimize the size control of the chip body. The limit opening 34 formed by the limit member 30 and the conveying surface, and the contact detection member arranged on the outer edge of the limit opening 34 can dynamically monitor the size of the chip body and adjust the position of the shearing structure 20 in time. This size control mechanism ensures that the size of the chip body will not be larger than the size of the limit opening 34 during the chip removal process, thereby avoiding the blockage of the limit opening 34. Secondly, by arranging a movable first shearing part 21 and a second shearing part 22 on the chip conveyor body 1, it can automatically identify and process large-sized chips and cut them into smaller chips, thereby avoiding the chips from entangled or blocking the chip removal port during the chip removal process, and significantly improving the chip removal efficiency and continuous operation capacity of the chip conveyor. The connection between the control member, the contact detection member and the shearing structure 20 realizes the automatic control of the chip size detection and the shearing action. There is no need for manual regular replacement and cleaning, which greatly reduces the need for manual intervention, improves the level of production automation, and saves labor costs. In addition, the combined design of the stopper 30 and the shearing structure 20 can adapt to chips of different sizes and types, including metal chips, plastic chips, etc., thereby improving the versatility and adaptability of the chip conveyor and making it suitable for a variety of processing environments and materials. Therefore, the machine tool provided in this embodiment can solve the technical problem in the prior art that the chip conveyor outlet is easily blocked when the chip mass is too large.

[0085] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: by installing a chip agglomeration device to cut off the chips, smooth chain plate transportation is ensured; by operating the chip cutting device through the cylinder, the chip conveyor is ensured to remove chips without manual regular replacement and cleaning.

[0086] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.
