Description

Technical Field

[0001] This utility model belongs to the technical field of machining equipment, specifically relating to a chip recycling device for machining centers. Background Technology

[0002] During machining operations such as cutting, milling, and drilling of metal workpieces in a machining center, a large amount of iron filings and coolant mixed in are typically generated. To ensure a clean machining environment and prevent iron filings from accumulating and affecting machine tool operation, an iron filings collection and processing mechanism is usually installed. In existing technologies, common iron filings collection methods mainly involve manual periodic cleaning or using a conveyor belt to guide the iron filings into a collection tank. However, these methods have the following shortcomings:

[0003] First, during the scrap collection process, coolant mixes with the scrap. If not separated effectively and promptly, this not only prevents the coolant from being recycled and increases consumable costs, but also easily leads to liquid accumulation inside the tank, causing corrosion or other safety hazards. Second, when the processing involves switching between workpieces of different materials or when the scrap needs to be cleaned in stages, existing devices usually require shutdown, affecting the continuous operation efficiency of the machining center. Third, some scrap collection devices lack a structure for controlling the diversion of processing waste. When the collection box is removed for cleaning, new waste scrap still falls into the recycling bin, causing different types of scrap to mix and affecting the quality of subsequent recycling.

[0004] In summary, existing scrap recycling devices still have certain technical problems in terms of the separation efficiency of scrap and coolant, the diversion and management of scrap of different materials, and the cleaning operation when the machine tool is not stopped. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a machining center scrap recycling device that is reasonable in structure, efficient in operation and easy to maintain.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A machining center scrap recycling device includes a machine tool body and a recycling device installed at the lower end of the machine tool body. The bottom of the machine tool body is provided with a base, and the lower end of the machine tool body is provided with openings on both the left and right sides of the base. The recycling device is U-shaped and wrapped around the outside of the base, and the recycling device collects the scrap discharged from the openings on the left and right sides.

[0008] The recycling device includes two boxes, left and right, and collection hoppers fixed at the openings on the left and right sides. The two collection hoppers are fixedly connected by a connecting corridor. The collection hoppers collect the waste discharged from the openings and discharge it downwards into the inside of the boxes. The inside of the boxes is equipped with a sealing plate that controls the opening and closing of the discharge port at the bottom of the collection hoppers. The inside of the boxes is also equipped with a collection box that collects the waste discharged from the collection hoppers and filters the waste liquid downwards. The collection box can be pulled out.

[0009] Furthermore, the inner bottom surface of the collection box is provided with evenly distributed sieve holes, and a handle is fixed to the front end of the collection box.

[0010] Furthermore, the surface of the sealing plate is provided with evenly distributed permeable holes, and both the front and rear sides of the sealing plate are provided with fixing plates fixed to the lower side of the hopper. The lower end of the fixing plate is fixed with a guide rail for moving the sealing plate left and right. The side of the sealing plate away from the base is provided with a drive mechanism fixed to the side wall of the box, and a drive plate connected to the drive mechanism is fixed to one side of the sealing plate.

[0011] Furthermore, the drive mechanism includes a motor fixed to the side wall of the housing and a lead screw threaded through the drive plate. One end of the lead screw is connected to the motor, and the other end of the lead screw is fixed with a stop block.

[0012] Furthermore, support plates for supporting the collection box are fixed on both the left and right side walls inside the box, and a cleaning port is opened on the side of the box away from the base, with an openable door panel installed at the cleaning port.

[0013] Furthermore, the lower end of the door panel is connected to the cabinet body by a hinge, and a card seat is fixed near the upper side of the door panel. A rotatable lock plate is installed at the corresponding position of the cabinet body and the card seat. The lock plate rotates downward and locks into the groove opened on the side of the card seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a U-shaped recycling device at the bottom of the machine tool body and collection hoppers installed at the openings on the left and right sides of the machine tool base. This allows the iron filings generated during the machining process to be effectively guided into the collection structure, thus preventing the disorderly accumulation or scattering of iron filings and contamination of the processing area. The recycling device is completely wrapped around the bottom of the machine tool, effectively improving the efficiency of centralized management of waste filings, improving the cleanliness of the processing site, and solving the problem of low efficiency and reliance on manual labor for iron filings cleaning in traditional processing.

[0016] This invention connects the left and right collection hoppers via a connecting corridor structure positioned in front of the workbench, effectively guiding and collecting chips falling from the front of the machine tool. The chips are guided by the corridor and discharged into the two side collection hoppers, then fed into a collection box at the bottom of the hoppers, achieving unified recycling of iron filings across the entire area and at multiple points. Simultaneously, the sieve structure at the bottom of the collection box allows for rapid filtration of coolant mixed with the iron filings, enabling it to seep down to the lower layer of the box for collection. This separates and recycles the iron filings and coolant, solving the problems of coolant waste and pollution in existing technologies.

[0017] This invention features a sealing plate structure inside the housing, which can be opened and closed by a drive mechanism. When the machine tool changes material or the collection box needs to be replaced, the sealing plate can be controlled by the drive mechanism to block the discharge port of the hopper, preventing subsequent waste chips from falling into the collection box and causing mixing of waste chips of different materials, thus ensuring the purity of the iron chip classification. The surface of the sealing plate is provided with a water-permeable hole structure, which allows the coolant to continue to be discharged even when the machine is closed, effectively ensuring the continuity of liquid recovery and avoiding liquid accumulation due to closing the discharge port.

[0018] This utility model adopts a drive mechanism composed of a motor, a lead screw, and a stop block, which can realize the precise movement of the sealing plate under the drive plate. The lead screw transmission has good stability and controllability, and the stop block setting ensures the limit range of the sealing plate operation, thereby ensuring the safety of equipment operation and sealing accuracy. This structure solves the problems of slow response and inconvenient manual operation of traditional sealing methods.

[0019] This invention ensures the stability of the collection box during the pulling process by setting support plates on both sides of the box, preventing waste spillage or structural jamming due to box tilting. In addition, a cleaning port with a locking mechanism is set on the side of the box away from the base, which facilitates regular cleaning of the internal collection area and ensures long-term stable operation of the equipment. The locking structure prevents the door from being accidentally opened when not in operation, avoiding liquid leakage that could affect the machine tool or operating environment.

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0029] like Figure 1 As shown, a machining center scrap recycling device includes a machine tool body and a recycling device installed at the lower end of the machine tool body. A base is provided at the bottom of the machine tool body, and openings are provided on both the left and right sides of the lower end of the machine tool body at the base. The recycling device is U-shaped and wraps around the outside of the base, collecting the scrap discharged from the openings on both sides. This structure enables the directional collection of scrap falling during machine tool processing, preventing scrap from scattering and polluting the processing environment. Compared to traditional manual cleaning or unorganized flow structures, this structure can achieve orderly scrap recycling even when the machine tool is running continuously, improving the continuity and efficiency of machine tool operation.

[0030] like Figure 2As shown, the recycling device includes two boxes 3 on the left and right sides and collection hoppers 1 fixed at the openings on the left and right sides. The two collection hoppers 1 are fixedly connected by a connecting corridor 6, which is used to collect the waste chips on the front side of the machine tool body's worktable and discharge them into the collection hoppers 1 on the left and right sides. The collection hoppers 1 collect the waste chips discharged from the openings and discharge them downwards into the inner side of the box 3. A sealing plate 2 is installed on the inner side of the box 3 to block and control the opening of the discharge port at the lower end of the collection hopper 1. A collection box 5 is installed on the inner side of the box 3 to collect the waste chips discharged from the collection hopper 1 and filter the waste liquid downwards. The collection box 5 can be pulled out. This structure, combined with the directional guiding effect of the collection hopper 1 and the separation and filtration function of the collection box 5, can realize the synchronous separation of iron filings and coolant. When it is necessary to clean or replace the collection box 5, it can be quickly removed through the pull-out structure to avoid coolant from mixing into the iron filings accumulation area, while ensuring that the inner wall of the box 3 is not corroded by long-term immersion in liquid.

[0031] like Figure 3 As shown, the inner bottom surface of the collection box 5 is provided with evenly arranged sieve holes 51, and the front end of the collection box 5 is fixed with a handle 52. The sieve holes 51 are used to perform preliminary coolant separation treatment on the collected iron filings, so that the coolant can smoothly seep into the bottom space of the box 3. The coolant drained through the sieve holes 51 can be further returned to the machine tool body for recycling through the drain pipe, thereby reducing coolant waste. The handle 52 structure makes it easy for the operator to take out the collection box 5 for cleaning without stopping the machine, improving the efficiency of iron filings removal and the convenience of operation.

[0032] like Figure 4 As shown, the surface of the sealing plate 2 is provided with evenly distributed water-permeable holes 21, and both the front and rear sides of the sealing plate 2 are provided with fixing plates 22 fixed to the lower side of the collecting hopper 1; the lower end of the fixing plate 22 is fixed with a guide rail 23 for guiding the sealing plate 2 to move left and right; a drive mechanism 24 is provided on the side of the sealing plate 2 away from the base and fixed to the side wall of the box 3, and a drive plate 25 connected to the drive mechanism 24 is fixed on one side of the sealing plate 2; when the machine tool processes workpieces of different materials or when the iron filings in the collecting box 5 need to be replaced, the sealing plate 2 can be moved by the drive mechanism 24 to block the outlet of the collecting hopper 1, preventing a new round of waste filings from entering the collecting box 5 and causing mixing; the water-permeable holes 21 can still allow coolant to permeate into the box 3 in the blocked state, ensuring that the liquid recovery process is not interrupted.

[0033] like Figure 5As shown, the drive mechanism 24 includes a motor 241 fixed to the side wall of the housing 3 and a lead screw 242 threaded through the drive plate 25; one end of the lead screw 242 is connected to the motor 241, and the other end of the lead screw 242 is fixed with a stop block 243; after the motor 241 is powered on, it drives the lead screw 242 to rotate, and the lead screw 242 drives the drive plate 25 to move linearly along the guide rail, so that the sealing plate 2 can achieve precise opening and closing; the stop block 243 plays a limiting role to prevent the sealing plate 2 from excessively displacing and causing structural interference with the housing 3 or the collection box 5; this transmission structure is responsive and precise in control, and is suitable for the dynamic management needs of waste chips under different processing cycles.

[0034] like Figure 6 As shown, support plates 34 are fixed on the left and right side walls of the box 3 to support the collection box 5. A cleaning port is provided on the side of the box 3 away from the base, and an openable door panel 31 is installed at the cleaning port. The support plates 34 are used to stabilize the position of the collection box 5 so that the collection box 5 remains horizontal during insertion and extraction, ensuring the normal operation of the iron filings and liquid separation function.

[0035] like Figure 6 As shown, the lower end of the door panel 31 is connected to the housing 3 by a hinge, and a card seat 32 is fixed near the upper side of the door panel 31. A rotatable locking plate 33 is installed in the housing 3 at the corresponding position of the card seat 32. The locking plate 33 rotates downward and locks into the groove opened on the side of the card seat 32. The opening and closing structure of the door panel 31 facilitates the periodic cleaning of the collection box 5 or the internal residual liquid. The hinge gives the door panel 31 good rotational freedom. The card seat 32 and the locking plate 33 together form a simple and efficient locking mechanism, which can reliably close the door panel 31 in the non-operational state, prevent coolant or waste from leaking out, and further improve the cleanliness and safety of the equipment.

[0036] The working principle of this utility model is as follows: When the machine tool body is processing the workpiece, the iron chips generated during processing will fall from the worktable and be collected by the collecting hopper 1. The iron chips collected by the collecting hopper 1 are discharged downward into the collecting box 5. At this time, the collecting box 5 collects the iron chips while filtering the coolant in it through the screen hole 51 and discharging it downward into the inner side of the box 3 for collection. The box 3 then uses the drain pipe 4 and the liquid pump to send the coolant back into the machine tool body, thereby completing the recycling of iron chips.

[0037] When the machine tool body is processing workpieces of other materials or when it is necessary to clean the iron filings in the collection box 5, the motor 241 is controlled to drive the lead screw 242 to rotate. The rotating lead screw 242 drives the drive plate 25 and the sealing plate 2 to move and block the discharge port at the lower end of the collection hopper 1, thereby intercepting the waste chips generated during processing to prevent them from mixing with iron filings. It also prevents the waste chips from falling into the box 3 without being collected by the collection box 5. The collection box 5 is removed and the collected waste is cleaned without stopping the machine tool body. This ensures that the cleaning of waste chips does not occupy the processing time of the machine tool body, thereby completing the continuous and efficient processing of the machine tool.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
