Description

Technical Field

[0001] This invention belongs to the field of shelf material cutting technology, specifically a cutting device for processing shelf materials. Background Technology

[0002] In existing technologies, raw materials (such as steel plates) on shelves are typically long and strip-shaped. During processing and cutting, a simple conveyor roller system combined with manual positioning or fixed stops is usually used for conveying and cutting. While this type of traditional cutting device can basically achieve the conveying and cutting of raw materials, it has the following significant technical drawbacks: Because the raw materials on the shelves are long and heavy, they are prone to lateral slippage or positional deviation when traveling on the conveyor rollers due to factors such as conveyor vibration, roller gaps, or uneven flatness of the raw materials themselves. This leads to inaccurate positioning of the cutting blades, resulting in skewed cuts and out-of-tolerance dimensions. This seriously affects the subsequent assembly accuracy of the shelves and the finished product qualification rate, resulting in a high scrap rate. Moreover, existing equipment mostly uses fixed pressure plates or manual adjustment mechanisms, which cannot automatically adapt to raw materials of different specifications and thicknesses. When changing materials, frequent machine stops are required to adjust the positioning components, which is time-consuming and labor-intensive, making it difficult to meet the continuous and efficient production requirements of modern production lines. In addition, the lack of effective pneumatic or linkage protection structures results in insufficient overall stability of the device, frequent maintenance, and high production costs.

[0003] In view of this, a cutting device for processing raw materials on shelves is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: Due to the long length and heavy weight of the raw materials on the rack, they are prone to lateral sliding or positional deviation when traveling on the conveyor roller frame due to factors such as conveyor vibration, roller gaps, or uneven flatness of the raw materials themselves. This leads to inaccurate action position of the cutting blade, resulting in skewed cuts and out-of-tolerance dimensions, which seriously affects the subsequent rack assembly accuracy and finished product qualification rate, resulting in a high scrap rate. Moreover, existing equipment mostly uses fixed pressure plates or manual adjustment mechanisms, which cannot automatically adapt to rack materials of different specifications and thicknesses. When changing materials, frequent machine stops are required to adjust the positioning components, which is time-consuming and labor-intensive, making it difficult to meet the continuous and efficient production requirements of modern production lines. In addition, the lack of effective pneumatic or linkage protection structures results in insufficient overall device stability, frequent maintenance, and high production costs.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cutting device for processing raw materials on a shelf, comprising a processing rack, a conveying channel, a cutting blade, and a raw material body; The transmission channel is preset at the center of the processing frame, and the cutting blade is set at the inner edge of the center of the transmission channel by a hydraulic cylinder for cutting the raw material body. The processing rack is equipped with a transmission roller frame at both openings of the transmission channel. The transmission roller frame is used to extend and support the raw material body and to transmit it. The raw material body is placed on the transmission channel and the transmission roller frame. The inner edge of the transmission channel is milled with a cavity and a guide channel. The number of guide channels is twice that of the cavity. Two guide channels are respectively arranged on both sides of the cavity, and the cavity and the guide channel are connected. The cavity is equipped with a telescopic motion correction module; The guide channel is equipped with an anti-tilting module that allows for telescopic movement.

[0009] As a preferred technical solution for a cutting device for processing raw materials on a shelf, the correction module includes a four-sided sealing plate, a U-frame, and a guide roller. The four-sided sealing plate and the U-frame are telescopically mounted in a cavity. One end of the U-frame extends out of the cavity and extends to the inner edge of the transmission channel. The four-sided sealing plate and the U-frame are connected by a connecting rod.

[0010] As a preferred technical solution for a cutting device for processing raw materials on a shelf, a guide roller is rotatably provided at one end of the U-frame that extends into the inner edge of the transmission channel, wherein the guide roller can ensure the normal transmission of the raw material body.

[0011] As a preferred technical solution for a cutting device used for processing raw materials on shelves, the four-sided sealing plate is provided with a guide channel.

[0012] As a preferred technical solution for a cutting device for processing raw materials on a shelf, the anti-tilting module includes an upper support, a chamfered frame, and a side sealing plate.

[0013] As a preferred technical solution for a cutting device for processing raw materials on a shelf, the top side of the side sealing plate is defined as an extension. The extension is located in the guide channel, and a wedge block is arranged on one side of the extension.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] This invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of this invention. In actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0029] Example 1, referring to Figures 1 to 6 A cutting device for processing raw materials on a shelf includes a processing rack 10, a conveying channel 12, a cutting blade 19, and a raw material body 20. The transmission channel 12 is preset at the center of the processing frame 10, and the cutting blade 19 is set at the inner edge of the center of the transmission channel 12 by a hydraulic cylinder for cutting the raw material body 20. The processing frame 10 is equipped with a transmission roller frame 14 at both opening positions of the transmission channel 12. The transmission roller frame 14 is used to extend and carry the raw material body 20 and to transmit it. The raw material body 20 is placed on the transmission channel 12 and the transmission roller frame 14. The inner edge of the transmission channel 12 is milled with a cavity 15 and a guide channel 16. The number of guide channels 16 is twice that of the cavity 15. The two guide channels 16 are respectively arranged on both sides of the cavity 15, and the cavity 15 and the guide channel 16 are connected. A control box 11 is located above the processing rack 10, and a curtain 13 is located at the upper edge of the transmission channel 12. The curtain 13 can protect the cutting process. A drainage channel 18 is provided on one side of the cavity 15, and an air pump 17 is installed on the side of the processing rack 10 near the drainage channel 18. The air pump 17 uses the drainage channel 18 to pump or transport gaseous media into the cavity 15.

[0030] Example 2, refer to Figure 5 , Figure 7 and Figure 8 The cavity 15 is equipped with a telescopic correction module 30, which includes a four-sided sealing plate 31, a U-frame 34, and a guide roller 35. The four-sided sealing plate 31 and the U-frame 34 are telescopically disposed in the cavity 15. One end of the U-frame 34 extends out of the cavity 15 and extends to the inner edge of the transmission channel 12. The four-sided sealing plate 31 and the U-frame 34 are connected by a connecting rod 33. The guide roller 35 is rotatably disposed at the end of the U-frame 34 that extends into the inner edge of the transmission channel 12. The guide roller 35 can ensure the normal transmission of the raw material body 20. A guide channel 32 is opened on the four-sided sealing plate 31.

[0031] Example 3, referring to Figure 3 , Figure 6 , Figure 7 and Figure 8The guide channel 16 is equipped with a telescopic anti-tilting module 40, which includes an upper support 41, a chamfered frame 42, and a side sealing plate 43. The upper support 41 telescopically moves up and down in the transmission channel 12, the chamfered frame 42 telescopically moves in the guide channel 16, and the chamfered frame 42 is connected to the upper support 41. The side sealing plate 43 telescopically moves in the cavity 15, and has an opening at its center. The side sealing plate 43 is located on the outer periphery of the connecting rod 33 through the opening. The bottom end of the upper support 41 is rotatably equipped with a guide roller 48 to facilitate the movement of the raw material body 20. The conveying; the top side of the side sealing plate 43 is defined as the extension 45, which is located in the guide channel 16. A wedge block 46 is arranged on one side of the extension 45. When the wedge block 46 moves toward the upper support 41, it can engage with the chamfering frame 42 to change the height of the chamfering frame 42. An elastic element 47 is provided between the chamfering frame 42 and the guide channel 16 to facilitate the pre-placement of raw material bodies 20 of different thicknesses. A protrusion 44 is arranged on one side of the side sealing plate 43, and the protrusion 44 is compatible with the specifications of the guide channel 32.

[0032] This implementation will achieve the following: S1. First, the raw material body 20 is placed on the processing frame 10 and conveyed by the transfer roller frame 14. After the end of the raw material body 20 that needs to be cut extends out, the air pump 17 injects gaseous medium into the guide channel 18. Initially, the gas directly pushes the four-sided sealing plate 31, connecting rod 33, and U-frame 34 towards the side of the raw material body 20. When the guide roller 35 contacts the periphery of the raw material body 20, the raw material body 20 is less likely to shift position during subsequent cutting and conveying, ensuring the integrity of the cut position. As the gaseous medium is continuously injected, the four-sided sealing plate 31, which remains stationary, will push the protrusion 44 separately. At this moment, the wedge block 46 will move toward the direction of the raw material body 20 and engage with the chamfering frame 42 in a wedge shape. At this moment, the chamfering frame 42 and the upper support 41 will move toward the upper surface of the raw material body 20. After contact, when the raw material body 20 is subsequently cut, it can ensure the flatness of the raw material body 20 during transportation and prevent the raw material body 20 from tilting, thus further improving the cutting effect. S2. The cutting blade 19 is driven by a hydraulic cylinder to cut the raw material body 20. S3. When changing the raw material body 20, the air pump 17 reacts to the flow channel 18. At this time, the side sealing plate 43 will be pulled. At this time, the wedge block 46 no longer produces a wedge effect on the chamfering frame 42. Under the action of the elastic element 47, the upper support 41 can move upward and then protrude 44 into the chamfering frame 42. As the extraction force continues, the four-sided sealing plate 31, along with the U frame 34 and the guide roller 35, moves away from the side of the raw material body 20, making it convenient for subsequent application and cutting of raw material bodies 20 of different specifications.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
