On the other hand, the separation of debris and cutting fluid is not thorough enough. The mixing of cutting fluid into the debris not only increases the difficulty of subsequent processing, but also may lead to the waste of cutting fluid, and it is impossible to achieve effective recycling.

DETAILED DESCRIPTION

[0028] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0029] Embodiment 1

[0030] like Figure 1-Figure 7 As shown, in this embodiment, a chip collection device for a horizontal machining center is provided, comprising a collection box 1 and a shaft tube 3 .

[0031] The collection box 1 is installed inside the processing machine tool.

[0032] One end of the shaft tube 3 extends to the bottom of the collection box 1 and is connected to the inside of the collection box 1 . The debris generated by the horizontal processing machine falls into the collection box 1 and is then transported through the shaft tube 3 connected to the collection box 1 .

[0033] Among them, a spiral rod 9 is installed in the shaft tube 3 for rotation. The spiral rod 9 in the shaft tube 3 rotates, and its spiral structure is used to transport the debris from the bottom of the collection box 1 upward along the shaft tube 3. The middle part of the spiral rod 9 is a middle structure, and the spiral rod 9 is attached to the inner wall of the shaft tube 3. A separation shell 4 is provided in the middle of the shaft tube 3, and a separation port 6 is provided at the bottom of the separation shell 4. A side blowing head 8 is installed on the separation shell 4. The blowing direction of the side blowing head 8 points to the inner arc surface of the separation shell 4 and toward the separation port 6. An inner blowing pipe 10 is installed at the inner center of the spiral rod 9. The inner blowing pipe 10 There are air holes for blowing air in all directions. When the gas passes through the spiral rod 9, the debris on the spiral rod 9 can be blown away. When the debris is transported to the separation shell 4 in the middle of the shaft tube 3, the side blowing head 8 blows air toward the inner arc surface of the separation shell 4 and toward the separation port 6, and the inner blowing pipe 10 blows air in all directions through the air holes. These two airflows work together to blow the debris on the spiral rod 9 away from the spiral rod 9 and discharge it from the separation port 6. The way in which the spiral rod 9 rotates to transport the debris can effectively transport the debris at the bottom of the collection box 1 into the shaft tube 3, avoiding the accumulation of debris at the bottom of the collection box 1. The setting of the side blowing head 8 and the inner blowing pipe 10 can clean the debris attached to the spiral rod 9 in time, prevent the debris from accumulating on the spiral rod 9 and affecting the transportation efficiency, and at the same time discharge the debris from the separation port 6, realizing the preliminary separation and collection of the debris.

[0034] Embodiment 2

[0035] like Figure 1-Figure 7 As shown, based on the first embodiment, this embodiment provides a structure of a separation shell 4, which is as follows:

[0036] The inner diameter of the separation shell 4 is larger than the inner diameter of the shaft tube 3. The side blowing device 5 is installed above the separation shell 4. The side blowing head 8 is connected to the air pipe 7 installed on the side blowing device 5. When the debris is transported to the separation shell 4 along with the spiral rod 9, the space suddenly increases, and the movement speed of the debris will be slowed down. The side blowing device 5 provides gas to the side blowing head 8 through the air pipe 7. The side blowing head 8 blows the gas into the separation shell 4 and uses the airflow to blow the debris toward the separation port 6. The increase in the inner diameter of the separation shell 4 reduces the movement speed of the debris therein, which is more conducive to the airflow blown by the side blowing head 8 to blow the debris away from the spiral rod 9 and guide it to the separation port 6, thereby improving the effect of debris separation.

[0037] A fixing plate 12 is fixed to the end of the shaft tube 3, and a support tube 14 is rotatably mounted on the fixing plate 12. The interior of the support tube 14 is a hollow structure. The support tube 14 is fixed to the end of the screw rod 9, and the fixing plate 12 plays a supporting and fixing role. The support tube 14 is rotatably mounted on the fixing plate 12 and is fixed to the end of the screw rod 9. When the screw rod 9 needs to rotate, the support tube 14 rotates on the fixing plate 12, providing a stable rotation support for the screw rod 9. The setting of the support tube 14 makes the screw rod 9 more stable during the rotation process, reducing the shaking and deviation of the screw rod 9 when rotating. A gear ring is fixed to the end of the support tube 14, and a gear is rotatably mounted on the fixing plate 12. The gear and the gear ring are connected by a hinge 15. A motor 13 for driving the gear to rotate is installed on the fixing plate 12. When the gear rotates, the gear ring is driven to rotate through the hinge 15, so that the support tube 14 rotates, and then drives the screw rod 9 fixed to the support tube 14 to rotate, realizing the power drive of the screw rod 9. This driving method has a simple structure and stable transmission, and can provide stable rotational power for the screw rod 9, thereby ensuring the normal operation of the screw rod 9.

[0038] The inner blow pipe 10 extends through the interior of the support pipe 14 to the exterior and is fixed to the air pipe 7, which provides gas to the inner blow pipe 10. The gas enters the inner blow pipe 10 through the air pipe 7, and then blows out from the air holes on the inner blow pipe 10 to the surroundings, blowing away the debris on the spiral rod 9. This connection method enables the inner blow pipe 10 to obtain a stable gas source, and by extending inside the support pipe 14, the inner blow pipe 10 is prevented from being disturbed during the rotation of the spiral rod 9, thereby ensuring the normal blowing function of the inner blow pipe 10.

[0039] Side blowing ports are provided on both sides of the side blowing head 8. The gas blown out of the side blowing ports overlaps with the gas blown out of the inner blowing pipe 10. The overlapping portion means that in the overlapping area, the two airflows interact with each other to form a stronger airflow field. When the debris passes through this area, it is subjected to a stronger airflow force and is more easily blown away from the spiral rod 9. The overlap of the two airflows enhances the effect of blowing away the debris, improves the efficiency of separating the debris from the spiral rod 9, and further ensures that there will not be too much debris accumulation on the spiral rod 9, thereby improving the working efficiency of the entire debris collection device.

[0040] Embodiment 3

[0041] like Figure 1-Figure 7 As shown, based on the first and second embodiments, this embodiment provides a method for collecting cutting fluid, which is as follows:

[0042] A liquid storage tank 2 is provided below the collection box 1, and a filter screen 11 is provided at the part of the shaft tube 3 located at the liquid storage tank 2. When the mixture containing debris and liquid enters the shaft tube 3, the filter screen 11 will filter the mixture at the part of the shaft tube 3 located at the liquid storage tank 2, and the liquid flows into the liquid storage tank 2 through the filter screen 11, while the debris continues to stay in the shaft tube 3 and is transported by the screw rod 9. The separation of debris and liquid is achieved, which is convenient for the recovery and treatment of liquid, and at the same time, it is avoided that the excessive accumulation of liquid in the shaft tube 3 affects the transportation of debris, and the purity and efficiency of debris collection are improved.

[0043] The shaft tube 3 is installed on the collection box 1 at an angle, and the end away from the collection box 1 is tilted upward. When the screw rod 9 rotates to transport the debris, the inclined angle of the shaft tube 3 is used to make the debris more smoothly transported upward under the combined action of gravity and the thrust of the screw rod 9, and the debris can be prevented from flowing back in the shaft tube 3. The inclined shaft tube 3 structure is conducive to the transportation of debris, reduces the resistance of the screw rod 9, improves the transportation efficiency, and avoids the blockage problem caused by the backflow of debris.

[0044] The bottom of the collecting box 1 is conical, and under the action of gravity, the debris will naturally gather toward the conical bottom, so as to enter the shaft tube 3 connected to the bottom of the collecting box 1, and then be transported by the screw rod 9. The conical bottom design allows the debris to enter the shaft tube 3 more smoothly, avoiding the debris from being dispersed and accumulated in the collecting box 1, and improving the efficiency and effect of debris collection.

[0045] A debris collection box 1 is provided at the bottom of the separation port 6. When the side blowing head 8 and the inner blowing pipe 10 blow the debris on the spiral rod 9 away and discharge it from the separation port 6, the debris directly falls into the debris collection box 1, realizing the centralized collection of the debris. It is convenient to uniformly handle the separated debris, avoid the debris from being scattered randomly, keep the inside of the processing machine clean, and also facilitate the subsequent recycling of the debris.

[0046] Working principle:

[0047] The mixture of chips and cutting fluid produced by the horizontal machining center falls into the collection box 1 installed inside the machine tool. Since the bottom of the collection box 1 is set in a conical shape, under the action of gravity, the chips will naturally gather to the bottom of the cone and enter the shaft tube 3 connected to the bottom of the collection box 1. The screw rod 9 in the shaft tube 3 rotates under the drive of the motor 13, and the motor 13 drives the gear on the fixed plate 12 to rotate. The gear drives the gear ring fixed to the end of the support tube 14 through the hinge 15 to rotate, thereby rotating the support tube 14, and then driving the screw rod 9 fixed to the support tube 14 to rotate. The screw rod 9 uses its spiral structure to transport the chips from the bottom of the collection box 1 upward along the inclined shaft tube 3. The shaft tube 3 is tilted and tilted upward at one end away from the collection box 1, so that the chips are more smoothly transported under the combined action of gravity and the thrust of the screw rod 9, while preventing the chips from flowing back.

[0048] When the mixture containing debris and liquid enters the shaft tube 3, the filter screen 11 will filter the mixture at the part of the shaft tube 3 located in the liquid storage tank 2. The liquid flows into the liquid storage tank 2 below the collection box 1 through the filter screen 11, achieving the preliminary separation of debris and liquid, facilitating the recovery and treatment of the liquid, and preventing excessive accumulation of liquid in the shaft tube 3 from affecting the transportation of debris.

[0049] When the debris is transported to the separation shell 4 in the middle of the shaft tube 3 along the spiral rod 9, the movement speed of the debris will be slowed down because the inner diameter of the separation shell 4 is larger than the inner diameter of the shaft tube 3. At this time, the side blowing device 5 provides gas to the side blowing head 8 installed on the separation shell 4 through the air pipe 7, and the side blowing head 8 blows air to the inner arc surface of the separation shell 4 and toward the separation port 6. At the same time, the air pipe 7 provides gas to the inner blowing pipe 10 that passes through the inside of the support tube 14 and extends to the outside to be fixed thereto, and the inner blowing pipe 10 blows air around through the air holes thereon. The gas blown out of the side blowing ports on both sides of the side blowing head 8 interacts with the gas blown out of the inner blowing pipe 10 in the overlapping area to form a stronger airflow field, blowing the debris on the spiral rod 9 away from the spiral rod 9, and causing it to be discharged from the separation port 6 at the bottom of the separation shell 4, and directly falling into the debris collection box 1 at the bottom of the separation port 6, thereby realizing the centralized collection and further separation of the debris.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
