DETAILED DESCRIPTION

[0033] The utility model will be further described in combination with the specific embodiments and the drawings, referring to Figs. 1-3 :

[0034] Embodiment 1:

[0035] The cutting chip collection device of the milling machine provided in the embodiment comprises:

[0036] A chip collecting box 1 with an opening at the top, which is used to receive the chips generated by the milling machine after working;

[0037] A chip flattening mechanism 2, which includes a flattening plate 20 with a smaller size than the opening of the chip collecting box 1, a plurality of chip inlet openings 21 evenly arranged on the flattening plate 20, a plurality of chip inlet opening openers 22 for controlling the opening and closing of each chip inlet opening 21, a driving component 23 for driving the flattening plate 20 to move up and down at the opening of the chip collecting box 1, and a guiding component 24 for preventing the flattening plate 20 from shaking during movement.

[0038] The chip collecting box 1 effectively avoids the scattering of chips, maintains the cleanliness and order of the milling machine working area, and provides convenience for subsequent centralized processing of chips, preventing the chips from causing adverse effects on equipment operation and working environment. The chip collecting box 1 is generally designed as a box structure with an opening at the top, and its shape is usually rectangular or square. The chip collecting box 1 is usually placed directly below the milling machine working area, and the natural force of gravity is used to make the chips fall smoothly from the milling machine processing site into the box, eliminating the need for additional conveying devices and simplifying the chip collection process.

[0039] The chip flattening mechanism 2 compacts and flattens the collected chips, aiming to improve the space utilization of the chip collecting box 1 and allow the chips to be more tightly and uniformly stacked in the box.

[0040] The flattening plate 20 is used to extrude loose chips into a more compact state, promoting the uniform and tight distribution of chips in the collecting box, improving the stacking density of chips, and fully utilizing the internal space of the collecting box. The flattening plate 20 is generally flat in structure, and its length and width are smaller than the corresponding length and width of the top opening of the chip collecting box 1. This design ensures that the flattening plate 20 can freely move up and down at the opening of the chip collecting box 1 without being hindered by the edges of the collecting box opening. The flattening plate 20 moves vertically up and down relative to the top opening of the chip collecting box 1 under the driving action of the driving component 23.

[0041] The chip inlet opening 21 ensures that the chips can be smoothly and efficiently transferred from the milling machine processing site to the chip collecting box 1 according to the predetermined path, realizing the orderly collection of chips and avoiding the blocking or scattering of chips during the transfer process. The chip inlet opening 21 is a uniform hole structure on the flattening plate 20, and its shape can be rectangular, which is used by the chip inlet opening opener 22.

[0042] The chip inlet opening opener 22 opens the chip inlet opening 21 in time during the chip collecting stage to ensure that the chips can smoothly enter the collecting box, and quickly closes the chip inlet opening 21 when the flattening plate 20 is pressed to flatten the chips, preventing the chips from overflowing upward under pressure and affecting the flattening effect and working environment.

[0043] The driving component 23 provides a stable and reliable power source for the up-down movement of the leveling plate 20, and is a key power assembly for realizing the chip leveling function.

[0044] The guiding component 24 is used to ensure that the leveling plate 20 remains stable during the up-down movement, prevents it from shaking, enables the chip leveling mechanism 2 to work normally and accurately, and ensures the smooth progress of the chip collection and leveling process.

[0045] Embodiment 2:

[0046] The embodiment provides a chip collection device of a milling machine, which has the following technical features in addition to the technical solutions of the above embodiments.

[0047] The corner of the leveling plate 20 is provided with a corner scraper 3 for preventing chips from accumulating at the corner of the chip collection box 1.

[0048] The corner scraper 3 is used to prevent chips from accumulating at the corner of the chip collection box 1. During the chip collection process, chips are prone to accumulate at the corner of the collection box. The corner scraper 3, through its special structure and working mode, timely scrapes the chips at the corner, ensures that the chips can be smoothly distributed in the collection box, and avoids excessive accumulation of chips at the corner, which affects the effective volume of the collection box and subsequent cleaning work. The corner scraper 3 can be triangular in shape. This triangular design can well fit the corner of the chip collection box 1. The bottom edge is used to connect with the corner of the leveling plate 20, and the top corner contacts the corner of the chip collection box 1 during the working process, realizing the function of scraping the chips. The corner scraper 3 can be tightly connected with the corner of the leveling plate 20 through bolts or adhesion.

[0049] Embodiment 3:

[0050] The embodiment provides a chip collection device of a milling machine, which has the following technical features in addition to the technical solutions of the above embodiments.

[0051] The corner scraper 3 has an extension 30 at both ends for scraping the residual chips on the inner wall of the chip collection box 1.

[0052] The extension 30 at both ends of the angle scraping plate 3 mainly functions to scrape the residual chips on the inner wall of the chip collection box 1. In the process of chip collection and flattening, in addition to the chips easily accumulated in the corners of the collection box, some chips are also left on the inner wall of the collection box. The extension 30 can clean the residual chips through its scraping effect, so that the chips can fall into the bottom of the collection box more thoroughly, and the efficiency of chip collection and the space utilization of the collection box are further improved. The extension 30 is connected with the main body of the angle scraping plate 3, and the cross-sectional shape of the extension 30 is consistent with the end of the angle scraping plate 3. The extension 30 and the main body of the angle scraping plate 3 are usually manufactured by an integral molding process, so that the connection between the two is firm, and the extension 30 and the main body are not separated during work.

[0058] The opening and closing handle 222 is used to move the telescopic blocking plate 221 to close the chip inlet 21 or retract the telescopic blocking plate 221 into the accommodating groove 220.

[0059] The accommodating groove 220 provides a space for the telescopic blocking plate 221 to move and ensures that the blocking plate can be properly stored in the flattening plate 20 when not in use, without affecting the normal entry of the chips. When it is necessary to block the chip inlet 21, the accommodating groove 220 provides a smooth movement track for the extension and retraction of the blocking plate. The accommodating groove 220 is a groove-shaped structure processed on the flattening plate 20. The groove is communicated with the chip inlet 21, and the size and shape of the groove are accurately matched with the telescopic blocking plate 221, so that the blocking plate can freely and smoothly slide in the groove.

[0060] The telescopic blocking plate 221 realizes effective blocking and opening of the chip inlet 21 through its transverse telescopic movement, and is a core execution component for the chip inlet opening and closing device 22 to realize the control function of the chip inlet 21. The telescopic blocking plate 221 is in a plate shape, one end of which is fixedly connected in the containing groove 220, and the other end of which can freely telescope in the transverse direction in the chip inlet 21. The telescopic blocking plate 221 is usually in a rectangular plate shape, which can best adapt to the shape of the chip inlet 21 and the containing groove 220, and ensure stability and sealing during telescoping. When not working, the telescopic blocking plate 221 is located in the containing groove 220 near one side of the chip inlet 21, and is in a standby state; when it is necessary to block the chip inlet 21, the telescopic blocking plate 221 can be telescopically extended in the transverse direction to the chip inlet 21 along the containing groove 220 until it completely covers the chip inlet 21; after work is completed, the telescopic blocking plate 221 is retracted into the containing groove 220. One end of the telescopic blocking plate 221 can be connected to the containing groove 220 by welding, bolt connection or other reliable fixing methods; the other end can freely slide in the chip inlet 21 through its nested structure.

[0061] The opening and closing handle 222 is an operating component for the operator to control the movement of the telescopic blocking plate 221, and provides a convenient force point for manual operation. The opening and closing handle 222 facilitates the operator to easily move the telescopic blocking plate 221 through manual operation, and realizes the opening and closing of the chip inlet 21, so that the operation of the chip inlet opening and closing device 22 is more intuitive and simple. The opening and closing handle 222 is usually designed in a shape convenient for the operator to grasp, such as a strip-shaped handle, a circular handle, a T-shaped handle, etc. The opening and closing handle 222 is installed at the movable end of the telescopic blocking plate 221, and is located in a prominent position, so that the operator can quickly find and hold it when necessary. The opening and closing handle 222 and the movable end of the telescopic blocking plate 221 can be tightly connected through welding, bolt connection or other reliable fixing methods.

[0063] The chip collecting device of the milling machine provided in the embodiment further has the following technical features in addition to the technical solutions of the above embodiments.

[0064] A magnetic attraction component 4 is arranged between the leveling plate 20 and the telescopic blocking plate 221, and the magnetic attraction component 4 comprises:

[0065] A fixed groove 40 is arranged on the leveling plate 20 corresponding to the containing groove 220;

[0066] A first magnetic attraction plate 41 is arranged in the fixed groove 40, and the movable side of the telescopic blocking plate 221 is provided with a second magnetic attraction plate 42 which is attracted to the first magnetic attraction plate 41.

[0067] The magnetic attraction part 4 stabilizes the telescopic closing plate 221 in the position of closing the chip inlet 21 by magnetic force, prevents the closing plate from moving due to accidents, avoids the leakage of chips from the chip inlet 21, and greatly improves the stability and reliability of the chip inlet opener 22.

[0068] The fixed groove 40 serves as a dedicated installation and fixing carrier of the first magnetic plate 41, provides a stable and accurate installation site for the first magnetic plate 41, and ensures that the first magnetic plate 41 can function on the leveling plate 20 and accurately dock with the second magnetic plate 42. The fixed groove 40 is a groove-shaped structure processed on the leveling plate 20, and the shape and size of the groove are strictly matched with the first magnetic plate 41. The shape is usually a rectangular groove, which is easy to process and can tightly fit the rectangular first magnetic plate 41, ensuring that the first magnetic plate 41 is stable after installation.

[0069] The first magnetic plate 41 and the second magnetic plate 42 attract each other and produce a strong magnetic attraction effect, firmly fixing the telescopic closing plate 221 that extends to close the chip inlet 21. The first magnetic plate 41 is usually in the shape of a rectangular plate, which is convenient for installation in the fixed groove 40 and can achieve large-area adsorption with the second magnetic plate 42, significantly enhancing the adsorption effect. The first magnetic plate 41 can be tightly connected with the fixed groove 40 by means of glue or screws.

[0070] The second magnetic plate 42 cooperates with the first magnetic plate 41 to attract each other and jointly achieve stable fixation of the telescopic closing plate 221. The second magnetic plate 42 and the first magnetic plate 41 are the same shape, both in the shape of a rectangular plate, which facilitates full contact during adsorption and improves adsorption stability. The second magnetic plate 42 can also be fixed on the outside of the telescopic closing plate 221 by means of glue or screws.

[0071] When the telescopic closing plate 221 extends to close the chip inlet 21, the first magnetic plate 41 installed in the fixed groove 40 of the leveling plate 20 and the second magnetic plate 42 installed on the movable side of the closing plate approach each other. Since both are made of strong magnetic materials, according to the principle of magnetic attraction between opposite poles, they produce a strong adsorption force that firmly fixes the closing plate in the position of closing the chip inlet 21, preventing it from moving due to external forces such as chip pressure and device vibration.
