Description

Technical Field

[0001] The present invention relates to the technical field of machine tool auxiliary equipment, in particular to a chip cutting device. Background Art

[0002] In the field of mechanical processing, chain plate chip conveyors are indispensable auxiliary equipment in the cutting process. They achieve efficient chip conveying through the continuous operation of circular chain plates. However, existing traditional chain plate chip conveyors have inherent structural design flaws. The gaps between the chain plates allow small chips to easily pass through these gaps and enter the center of the circular chain plates during chip conveying.

[0003] When chips enter the middle of the chain, they first cause accumulation and contamination. As the chips continue to accumulate, they hinder the chain's normal operation, causing the chip conveyor to frequently jam. This persistent jamming not only severely impacts the conveyor's efficiency but also places abnormal stresses on the chain and transmission components, accelerating component wear and significantly shortening the conveyor's service life.

[0004] Since chip accumulation is unavoidable, regular machine downtime for manual cleaning is required to ensure the normal operation of the chip conveyor. Frequent downtime for cleaning not only interrupts the production process and seriously affects production efficiency, but also increases labor costs and equipment maintenance costs, negatively affecting the company's economic benefits.

[0005] When it comes to chip removal, traditional chain-plate chip conveyors lack an effective active cleaning mechanism. Chips that enter the conveyor primarily rely on gravity to naturally fall out. However, in actual operating conditions, chips can become entangled and adhere to each other, or be affected by the airflow generated by the chain's operation, making it difficult for gravity to completely expel them from the intermediate space. This results in low separation efficiency and further exacerbates the problem of chip accumulation. These technical challenges have long constrained the effectiveness of chain-plate chip conveyors and urgently require technological innovation to address them. Summary of the Invention

[0006] In view of the fact that the above-mentioned broken chips easily accumulate inside the chain plate belt, causing problems such as the chip removal device being stuck and parts being worn, it is necessary to propose a chip removal device that can actively discharge the chips entering the middle of the chain plate, thereby reducing the maintenance workload of the chip removal device.

[0007] A chip removal device comprises a frame, a chain plate arranged on the frame, and a guide mechanism arranged in an annular space of the chain plate; the frame is the supporting skeleton of the chip removal device; the chain plate is used to receive and transport chips, and is provided with a conveying area and a channel area, and the channel area is used for chip removal; the guide mechanism is used to guide the chips to the channel area to realize the non-jamming operation of the chip removal device.

[0008] As a supplement to the present technical solution, the chip removal device further includes a maintenance port, which is arranged on both sides of the guide mechanism for timely maintenance of the guide mechanism to avoid blockage of the guide mechanism.

[0009] As a supplement to the present technical solution, the chip removal device also includes a cleaning mechanism, which is arranged on the inner side of the chain belt to clean the chips hanging or stuck on the chain belt, thereby enhancing the chip conveying efficiency and reducing the risk of poor chip conveying caused by chips being retained on the chain belt.

[0010] The beneficial effects of the technical solution of the present invention are as follows: through the guide mechanism arranged on the chain plate, the guide mechanism realizes the automatic discharge of chips on the chain plate by guiding the chips to the channel area, thereby improving the chip removal efficiency of the chip removal device; and the dual-area setting of the chain plate ensures the normal transportation of chips and also realizes the automatic discharge of chips in the chain plate interlayer.

[0017] In order to more clearly illustrate the technical solution of the present invention, the technical solution of the invention content is described in detail with reference to the accompanying drawings. Obviously, the following descriptions are some typical embodiments of the present invention. For ordinary technicians in this field, other solutions can be obtained based on these embodiments without paying any creative work.

[0018] In one embodiment, the chip removal device of the technical solution of the present invention is implemented in the chip removal of machine tools. The specific examples are as follows.

[0019] In this embodiment, the chip removal device includes a frame, a chain plate belt arranged on the frame, and a guide mechanism arranged in the annular space of the chain plate belt; the frame is the supporting skeleton of the chip removal device; the chain plate belt is used to receive and transport chips, and is provided with a conveying area and a channel area, the channel area is used for chip removal; the guide mechanism is used to guide the chips to the channel area, so as to achieve non-jamming operation of the chip removal device. Figure 1-5 Shown is a chip conveyor with automatic cleaning function.

[0020] In this embodiment, several independent chain plates 7 are connected end to end to form a ring-shaped chain plate belt 8, and each independent chain plate 7 is divided into a transport area 702 and a channel area 701 in parallel in a direction parallel to the running direction. The transport area 702 is used to transport the chips to the chip dropping area, and the channel area 701 is used to drop the chips, that is, to make the chips fall off the chain plate belt 8.

[0021] As a supplement to this embodiment, to facilitate the collection of chips, a chip drop opening 1 is provided in the conveying area 702. This opening 1 is generally funnel-shaped, with a small opening facing the conveying area 702 and a large opening pointing vertically upward to receive chips. Furthermore, to prevent chips from falling into the channel area 701, one sidewall of the chip drop opening 1 extends above the channel area 701, providing protection for the channel area 701. Specifically, the large opening of the chip drop opening 1, which serves as the material drop entrance, projects vertically from the chain plate over the channel area 701, effectively preventing chips from falling into the channel area 701.

[0022] As a further supplement to this embodiment, the channel area 701 includes a channel opening 703, a baffle 705 and a baffle 706 for chip dropping; the channel opening 703 is composed of a number of connecting rods with equal or unequal spacing, one end of the connecting rod is arranged on the side end face of the chain plate 7, and the other end is connected to the baffle 706; the baffle 706 is arranged at the intersection of the channel area 701 and the conveying area 702, and the two surfaces of the baffle 706 are respectively connected to one end of the channel area 701 and the conveying area 702; the baffle 705 is arranged parallel to the connecting rod, and the length of the baffle 705 is not less than the width of the channel area 701, and one end of the baffle 705 is connected to the side end face of the chain plate 7, and the other end is suspended.

[0023] Specifically, in order to prevent the broken chips between the chain plates 7 connected end to end in the running direction from entering the channel area 701 of the next chain plate 7, a baffle 705 is further provided at the chain plates 7 connected to each other at the same width as the channel area 701. The baffle 705 can prevent the broken chips on the current chain plate 7 from entering the channel area 701 of the next chain plate 7, and can fall out of the interlayer of the chain plate belt 8 through the channel area 701 on the current chain plate 7 in time, thereby reducing the jamming of the chain plate belt 8 caused by the broken chips hanging on the interlayer of the chain plate belt 8.

[0024] Specifically, a baffle 706 is provided at the junction of the channel area 701 and the conveying area 702 , and the baffle 706 is used to prevent chips from falling into the channel area 701 during the conveying process and blocking the channel area 701 .

[0025] As a supplement to this embodiment, the frame is generally Z-shaped, comprising a short transverse section, an inclined section, and a long transverse section. The frame is also equipped with a transmission assembly 4, a steering shaft 5, and a filter assembly. The transmission assembly 4 and steering shaft 5 are located at either end of the frame, while the filter assembly is located in the middle. Specifically, the transmission assembly 4 is located in the short transverse section to provide operating power for the chain plate belt 8. The steering shaft 5 is located at the end of the long transverse section away from the inclined section to change the direction of the chain plate belt 8, achieving an endless loop of the chain plate belt 8. Several filter assemblies are provided, each located below the chain plate 7 arranged on the long transverse section near the inclined section.

[0026] As a further supplement to this embodiment, two filter assemblies are provided in the front and rear positions in the direction of travel of the chain plate belt 8. The filter assembly includes a filter frame 3 and a filter frame mounting hole 9. The filter frame mounting hole 9 is symmetrically arranged on the side end surface of the long transverse section. The filter frame 3 is mounted on the filter frame mounting hole 9. The filter frame 3 is used to receive the cutting fluid containing broken chips from the chain plate belt 8 and filter the broken chips therein, thereby realizing the recycling and reuse of the cutting fluid. More preferably, to facilitate the recovery of the filtered and reusable cutting fluid, the bottom surface of the frame corresponding to the long transverse section is configured to be inclined toward the middle of one side to facilitate the collection of the cutting fluid.

[0027] As a supplement to this embodiment, the guide mechanism 6 is arranged side by side and parallel to the steering shaft 5 in the annular space of the chain belt 8. With respect to the running direction of the chain belt 8, the guide mechanism 6 is arranged side by side in front of the steering shaft 5 to clean the broken chips hanging in the annular space of the chain belt 8, and guide the cleaned broken chips to the channel area 701, so that the broken chips stuck and hanging inside the annular space of the chain belt 8 are cleaned and fall away from the chain belt 8, avoiding the problem of the chain belt 8 being stuck due to too many broken chips being stuck.

[0028] As a further supplement to this embodiment, in order to conveniently guide the broken chips from the conveying area 702 to the channel area 701, the cross-section of the guide mechanism 6 is a right-angled trapezoid, with two right-angled sides respectively provided on the side walls of the frame, and the upper base of the guide mechanism 6 is close to the side wall of the frame with the conveying area 702, so that the guide mechanism 6 is inclined from the conveying area 702 to the channel area 701, thereby achieving smooth guidance of the broken chips. Alternatively, the two right-angled side walls of the guide mechanism 6 are connected to the bracket that fixes the chain plate 7, and the surface distance of the guide mechanism 6 from the annular space formed by the chain plate 7 facing the chain plate belt 8 can be fixed, so that the broken chips hanging in the annular space of the chain plate belt can be effectively cleaned. On the other hand, the surface distance of the guide mechanism 6 from the annular space formed by the chain plate 7 facing the chain plate belt 8 can also float within a certain range, thereby avoiding the problem of the chip removal device being stuck due to the obstruction between the chips and the guide mechanism 6.

[0029] As a further supplement to this embodiment, in order to facilitate the maintenance or inspection of the guide mechanism 6, maintenance ports 2 are also provided on the side walls of the frame corresponding to the guide mechanism 6. By cleaning the guide mechanism 6 in time, blockage of the guide mechanism is avoided, and the long-term normal operation of the chip removal device is ensured.

[0030] As a supplement to this embodiment, the chip removal device also includes a cleaning mechanism, which is arranged on the inner side of the chain plate belt to clean chips that are stuck or stuck on the chain plate belt, thereby enhancing the chip conveying efficiency and reducing the risk of poor chip conveying caused by chips being trapped on the chain plate belt. Specifically, the sand cleaning mechanism is a scraper 704 arranged in the conveying area 702, the length of the scraper 704 being no greater than the width of the conveying area 702, and being used to clean chips that are stuck in the conveying area 702; and one scraper 704 is provided on each chain plate 7, and the scraper 704 is provided at the front end of each chain plate 7 in the direction of operation.

[0031] In another embodiment, the chip removal device of the present invention operates as follows:

[0032] The chips enter the conveying area 702 of the chain plate 7 of the chip removal device from the chip drop opening 1; the chip drop opening 1 provided on the conveying area 702 effectively prevents the chips from entering the channel area 701;

[0033] The transmission assembly 4 drives the chain plate belt 8 to rotate, transporting the chips from the long horizontal section to the short horizontal section, thereby transporting the chips out of the machine tool;

[0034] When the chain plate 7 carrying the chips runs to the steering shaft 5, the guide mechanism 6 arranged in front of the steering shaft 5 scrapes the broken chips hanging or clamped on the back of the chain plate 7 or in the annular space of the chain plate belt 8 off the chain plate 7 and guides them to the channel area 701;

[0035] The broken chips guided to the channel area 701 fall out of the chip removal device through the channel opening 703, thereby automatically cleaning the internal space of the chip removal device and improving the normal operation efficiency of the chip removal device.

[0036] As a supplement to this embodiment, the filter frame 3 arranged below the transport area 702 effectively recycles the cutting liquid mixed with broken chips received from the transport area 702 by filtering the cutting liquid; in order to enable the cutting liquid to pass through the transport area 702 and fall into the filter frame 3, the transport area 702 is provided with a through structure, and the through structure can be arranged in a through hole. In this embodiment, in order to reduce the risk of chips hanging on the through structure, the through structure can be a circular through hole.

[0037] The above embodiment is only a description of a typical application of the technical solution of the present invention, and reasonable expansion can be made on a reasonable basis without requiring creative work.
