Description

Technical Field

[0001] This utility model relates to chip conveyors, specifically, to a spiral chip conveyor. Background Technology

[0002] Spiral chip conveyors are often installed on machining tools to transport the waste chips generated by the machine tool. For example, Chinese patent CN209288857U provides a spiral chip conveyor base, including a base with a worktable in the middle and chip removal grooves on both sides of the worktable, a spiral chip removal mechanism disposed in the chip removal grooves, and a power component fixed to the base. The tail of the base has a chip removal through hole that communicates with the chip removal groove. The spiral chip removal mechanism includes a spiral component disposed in the chip removal groove, with its tail extending out of the chip removal groove. The power component drives the spiral component to rotate. In chip conveyors such as those described above, two chip conveyors are connected by a chip removal ramp. After the waste chips enter the chip removal ramp, they slide down into the chip conveyors on both sides for transport. In actual operation, the waste chips often contain cutting fluid, and the waste chips easily stick together on the chip removal ramp, preventing them from completely sliding down into the chip conveyor. Utility Model Content

[0003] The purpose of this invention is to provide a spiral chip conveyor that solves the problem in the existing chip conveyor technology where two chip conveyors are connected by a chip conveying ramp. In actual operation, the chips often contain cutting fluid, and the chips tend to stick together on the chip conveying ramp, preventing them from completely sliding into the chip conveyor.

[0004] To achieve the above objectives, this utility model provides a spiral chip conveyor, which includes two sets of chip conveyors arranged at intervals.

[0005] The chip conveyor includes a housing, the ends of the two housings are connected by a back plate, and a horizontal guide plate is provided on the back plate, with both ends of the guide plate extending to the top of the housing;

[0006] A scraper is slidably disposed on the back plate, and the bottom of the scraper contacts the guide plate, so that the scraper can move back along the length direction of the guide plate.

[0007] Preferably, a groove is formed on the back plate along its length, a sliding seat is slidably engaged on the groove, and the scraper is locked onto the sliding seat by a screw assembly;

[0008] The bottom of the scraper has a locking groove, and a rubber scraper strip is engaged in the locking groove.

[0009] Preferably, a mounting base is provided on the back of the back plate, a lead lever is rotatably mounted on the mounting base, a lead screw nut is sleeved on the lead lever, a sliding seat is connected to the lead screw nut, a motor is fixed on the mounting base, and the output shaft of the motor is coaxially connected to the lead lever.

[0010] Preferably, the side of the guide plate away from the back plate is bent to form an inclined structure.

[0011] Preferably, the chip conveyor further includes a push screw disposed within the housing, one end of the housing is provided with a drive motor, and the other end forms an outlet, the output shaft of the drive motor being coaxially connected to the push screw.

[0012] Beneficial Effects: This utility model provides a spiral chip conveyor, which includes two sets of chip conveyors spaced apart. Each chip conveyor includes a housing, with the ends of the two housings connected by a back plate. A horizontal guide plate is provided on the back plate, with both ends of the guide plate extending above the housing. A scraper is slidably provided on the back plate, with its bottom contacting the guide plate, allowing the scraper to move backward along the length of the guide plate. Here, the chip conveyors are located on both sides of the machine tool, and the guide plate is connected to the machine tool table. The waste chips generated by the machine tool can enter the guide plate along with the cutting fluid. By the left and right displacement of the scraper, the waste chips can be pushed intermittently into the housing on the left or right side for conveying. Compared with the inclined chip conveying structure in the prior art, this avoids the problem of waste chips and cutting fluid sticking to the inclined chip conveying structure, which would cause poor sliding.

[0013] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0022] like Figure 1-4 As shown: This utility model provides a spiral chip conveyor, which includes two sets of chip conveyors spaced apart. Each chip conveyor includes a housing 1, with the ends of the two housings 1 connected by a back plate 5. A horizontal guide plate 4 is provided on the back plate 5, with both ends of the guide plate 4 extending above the housing 1. A scraper 9 is slidably provided on the back plate 5, with the bottom of the scraper 9 contacting the guide plate 4, allowing the scraper 9 to move backward along the length of the guide plate 4. Here, the chip conveyors are located on both sides of the machine tool, with the guide plate connected to the machine tool table. Waste chips generated by the machine tool, along with cutting fluid, can enter the guide plate. Through the left and right displacement of the scraper, the waste chips can be pushed intermittently into the left or right housing for transport. Compared to the inclined chip conveying structure in the prior art, this avoids the problem of waste chips and cutting fluid adhering to the inclined chip conveying structure, thus preventing poor sliding.

[0023] In a preferred embodiment of the present invention, in order to limit the displacement of the scraper, a groove 7 is formed on the back plate 5 along its length direction, a sliding seat 8 is slidably engaged on the groove 7, and the scraper 9 is locked on the sliding seat 8 by a screw assembly.

[0024] The bottom of the scraper 9 has an engaging groove, in which a rubber scraper strip 10 engages. The rubber scraper strip prevents the scraper from making hard contact with the surface of the guide plate.

[0025] In a preferred embodiment of this utility model, a mounting base 11 is provided on the back of the back plate 5. A lead lever 12 is rotatably mounted on the mounting base 11, and a lead screw nut 13 is sleeved on the lead lever 12. The sliding seat 8 is connected to the lead screw nut 13. A motor 14 is fixed on the mounting base 11, and the output shaft of the motor 14 is coaxially connected to the lead lever 12. By rotating the motor forward and backward, the lead screw nut can reciprocate on the lead lever, thereby scraping the waste from the guide plate into the left and right outer shells at intervals.

[0026] In a preferred embodiment of this invention, the guide plate 4 has a bend forming a sloping structure 6 on the side away from the back plate 5. This sloping structure connects to the machine tool table.

[0027] In a preferred embodiment of the present invention, the chip conveyor further includes a push screw 2 disposed inside the housing 1. One end of the housing 1 is provided with a drive motor 3, and the other end forms an outlet. The output shaft of the drive motor 3 is coaxially connected to the push screw 2.
