[0021] Reference Figure 1~Figure 4 , which is the first embodiment of the present invention, proposes a corner protector machine capable of producing paper corner protectors of various specifications, including a paper feeding assembly 1 and a forming mechanism 2, wherein the forming mechanism 2 includes a frame 4 having a paper feeding channel 401; a mounting frame 5 is arranged on a side of the frame 4; a forming shaft 7 is penetrated and rotatably arranged on the mounting frame 5, the forming shaft 7 has a forming groove 8, and a plurality of forming grooves 8 are arranged on the forming shaft 7 at intervals along the axial direction of the forming shaft 7; an auxiliary plate 11 is sleeved on the forming roller shaft, and the auxiliary plate 11 is located on the mounting frame 5. On the inner side, after the molding groove 8 moves to the inner side of the mounting frame 5, the auxiliary disk 11 is arranged on both sides of the molding groove 8, and the auxiliary disk 11 is used to assist the molding groove 8 in processing the paper to be molded; the molding disk 12 is lifted, slid and rotatably arranged on the mounting frame 5, and the molding disk 12 has an installation space; there are a plurality of molding wheels 13, and a plurality of molding wheels 13 are rotated at intervals in the installation space, each molding wheel 13 corresponds to a molding groove 8, and the molding wheel 13 and the molding groove 8 form a processing space 14, and the processing space 14 is connected to the paper feeding channel 401.

[0022] In the above scheme, the paper feeding assembly 1 is responsible for conveying the paper to the subsequent forming mechanism 2 in a certain rhythm and direction. The common rollers and conveyor belts can be used to achieve stable paper feeding to ensure that the paper can smoothly enter the forming area. The frame 4 as a whole serves as a supporting structure, and a paper feeding channel 401 is arranged inside it, which provides a predetermined route for the transmission of the paper and ensures that the paper can accurately reach the forming part. The mounting frame 5 is located on one side of the frame 4 and plays the role of installing other forming components. The forming shaft 7 penetrates and is rotatably arranged on the mounting frame 5. A number of forming grooves 8 are arranged at intervals along its axial direction. These forming grooves 8 shape the paper. The forming grooves 8 with different intervals and shapes can meet the forming requirements of different specifications of paper corner guards. The auxiliary disk 11 is sleeved on the forming shaft 7 and located on the inner side of the mounting frame 5. After the forming groove 8 moves to the inner side of the mounting frame 5, the auxiliary disk 11 is on both sides of the forming groove 8. Its shape and position can help better guide the paper to be formed in the forming groove 8, and assist in the precise bending and other processing operations of the paper. The forming disc 12 can be lifted, slid and rotated on the mounting frame 5, and has an installation space inside, which provides a suitable accommodation area for the setting of the forming wheel 13. There are a plurality of forming wheels 13, which are arranged in the installation space of the forming disc 12 at intervals and rotate, and each forming wheel 13 corresponds to a forming groove 8, and the two together form a processing space 14, which is connected to the paper feeding channel 401, so that paper can enter the processing space 14 from the paper feeding channel 401, and the forming and shaping of the paper corner guard is completed through the cooperation of the forming wheel 13 and the forming groove 8.

[0023] Working process: the paper feeding assembly 1 conveys the paper along the paper feeding channel 401 of the frame 4, and the paper enters the processing space 14 of the forming mechanism 2. At this time, the forming shaft 7 rotates under the power drive, driving the forming groove 8 thereon to rotate. When the forming groove 8 rotates to the inside of the mounting frame 5, the auxiliary plate 11 assists the paper to better fit in the forming groove 8 for preliminary shape bending. At the same time, the corresponding forming wheel 13 is also rotating. Through cooperation with the forming groove 8, the paper is further squeezed, bent and other processing operations are performed on the paper, so that the paper gradually forms a paper corner protector shape that meets the requirements. With the continuous rotation of the shaft and the continuous conveying of the paper, the forming process of the paper corner protector is continuously completed. By arranging a plurality of forming parts of different specifications represented by the forming grooves 8 on the forming shaft 7, it is possible to produce paper corner protectors of various specifications without frequently replacing a large number of molds like the traditional corner protector machine, thereby improving production efficiency, reducing equipment downtime for operations such as mold replacement, and reducing maintenance costs; and the processing method in which the forming wheel 13 and the forming groove 8 cooperate helps to improve the forming accuracy of the paper, reduce problems such as irregular forming and large dimensional deviation, and ensure the performance and appearance quality of the paper corner protector.

[0024] Furthermore, the mounting frame 5 has a slide groove 501, and the forming disk 12 includes a fixed shaft 1201, which is lifted, slidably and rotatably arranged in the slide groove 501; there are two conical disk bodies 1203, and the two conical disk bodies 1203 are symmetrically arranged on the fixed shaft 1201, and an installation space is formed between the two conical disk bodies 1203, and the wheel axles of the forming wheels 13 are all located in the installation space and close to the edge of the conical disk body 1203; the adjusting member 1202 is arranged on the mounting frame 5, and the adjusting member 1202 is transmission-connected to the fixed shaft 1201, and the adjusting member 1202 is used to adjust the position of the fixed shaft 1201 in the slide groove 501.

[0025] In the above scheme, the slide groove 501 of the mounting frame 5 provides a guide and limit function for the movement of the forming disk 12, so that the forming disk 12 can be lifted, slid and rotated in its limited direction. The fixed shaft 1201 is a key support and connection component of the forming disk 12. It can be lifted, slid and rotated in the slide groove 501 of the mounting frame 5, so as to adjust the overall position and posture of the forming disk 12 to adapt to different processing requirements. There are two conical disk bodies 1203 and they are symmetrically arranged on the fixed shaft 1201, and an installation space is formed between the two. On the one hand, it is conducive to the reasonable arrangement of the forming wheel 13 in the limited space, and on the other hand, it can also guide and gather the paper forming to a certain extent. The axle of the forming wheel 13 is located in the installation space and close to the edge of the conical disk body 1203, which is convenient for processing with the corresponding forming groove 8.

[0026] The adjusting member 1202 is arranged on the mounting frame 5 and is connected to the fixed shaft 1201 in transmission. Common transmission forms such as a screw-nut mechanism, a gear rack mechanism, etc. can be adopted. By operating the adjusting member 1202, the position of the fixed shaft 1201 in the slide groove 501 can be accurately changed, thereby adjusting the overall height and other position states of the forming disk 12.

[0027] Working process: When it is necessary to produce paper corner protectors of different specifications and have different requirements for the position of the forming disk 12, the operator operates the adjusting part 1202, such as rotating the screw rod. Assuming that a screw nut mechanism is used as the adjusting part 1202, the screw rod drives the fixed shaft 1201 to lift and slide in the slide groove 501 of the mounting frame 5, thereby changing the height position of the forming disk 12, and the two conical disk bodies 1203 and the forming wheels 13 therein are also moved to the appropriate positions and realigned with the corresponding forming grooves 8 on the forming shaft 7 to adapt to the forming processing of the new specifications of paper corner protectors. During the processing, the forming disk 12 stably assists in completing the paper forming operation as the paper is conveyed and the forming wheel 13 rotates.

[0028] Beneficial effects: The position of the forming disk 12 can be adjusted conveniently and accurately, making the cooperation between the forming wheel 13 and the forming groove 8 more flexible and diverse, further enhancing the adaptability of the corner protector to the production of paper corner protectors of different specifications, while improving the versatility of the equipment, it can still ensure good paper forming accuracy, thereby improving product quality and production efficiency.

[0029] Furthermore, it also includes extension frames 9, which are provided in plurality. The extension frames 9 are respectively arranged on both sides of the installation frame. Both ends of the forming shaft 7 respectively pass through and are slidably arranged in the extension frames 9. The extension frames 9 are used to assist in supporting the forming shaft 7.

[0030] In the above scheme, there are several extension frames 9, which are respectively arranged on both sides of the installation frame. There is a suitable space inside the extension frames to allow the two ends of the forming shaft 7 to pass through and slide therein. The extension frames 9 have sufficient structural strength and can be made of metal materials, which provides additional support for the forming shaft 7, enhances the stability of the forming shaft 7 during operation, and avoids shaking due to reasons such as the shaft being too long that affects the processing accuracy.

[0031] Working process: When the corner protector machine is working normally, the forming shaft 7 rotates under power drive, and at the same time, the two ends slide and cooperate in the extension frame 9. The extension frame 9 always provides it with stable supporting force. No matter the forming shaft 7 rotates at high speed or carries paper for processing and generates a certain force, the extension frame 9 can ensure the smooth operation of the shaft and ensure that each forming groove 8 can accurately cooperate with the forming disk 12 and other components to complete the forming work of the paper corner protector.

[0032] The stability of the forming shaft 7 is effectively improved, thereby improving the working stability of the entire forming mechanism 2, helping to improve the forming accuracy of the paper corner protector, reducing the processing error caused by the unstable shaft, ensuring product quality, and also extending the service life of the forming shaft 7 and the entire equipment.

[0033] Furthermore, the extension frame 9 has a through slot, and also includes a shift fork 10 that penetrates and is slidably disposed in the through slot. The shift fork 10 is clamped on the forming shaft 7 , and the shift fork 10 is used to adjust the position of the forming shaft 7 in the extension frame 9 .

[0034] In the above scheme, the extension frame 9 has a through-slot structure, and the size and shape of the through-slot are adapted to the fork 10, providing space for the sliding of the fork 10. The fork 10 is inserted through and slidably arranged in the through-slot, and can be clamped with the molded shaft 7. The fork 10 can be made of a metal component with a certain strength and a suitable shape, and the clamping mode of the fork 10 and the molded shaft 7 can be a clamping slot and a clamping block, etc., which is convenient to operate and has a stable connection. By sliding the fork 10 in the through-slot, the relative position relationship between the fork 10 and the molded shaft 7 can be changed, thereby adjusting the position of the molded shaft 7 in the extension frame 9.

[0035] Working process: When it is necessary to fine-tune the position of the forming shaft 7 in the extension frame 9, the operator manually pushes the fork 10 to slide it in the through slot of the extension frame 9. The fork 10 drives the forming shaft 7 to move accordingly in the extension frame 9. After adjusting to the appropriate position, the clamping structure between the fork 10 and the shaft can ensure that the shaft is fixed in this position, so that the subsequent forming shaft 7 cooperates with other components to form the paper corner protector, for example, to ensure that the forming groove 8 can be accurately aligned with the forming wheel 13 and other components to ensure processing accuracy. The position of the forming shaft 7 can be adjusted more finely, further improving the accuracy of the coordination between the various components of the equipment, which helps to improve the forming quality of the paper corner protector. In addition, the operation is convenient and quick, and the position adjustment can be completed without complicated disassembly and other operations.

[0036] Furthermore, the number of the forming discs 12 is the same as the number of the forming grooves 8, and the cross-sectional shapes of the correspondingly arranged forming discs 12 and forming grooves 8 are adapted to each other.

[0037] In the above scheme, the number of forming disks 12 is the same as the number of forming grooves 8, and the corresponding cross-sectional shapes thereof are adapted to each other. For example, if the forming groove 8 is a rectangular cross-section, the corresponding cross-sectional shape of the forming disk 12 is also a rectangular-related shape that can fit closely therewith so that the paper can be smoothly formed between the two. This one-to-one adaptation relationship ensures that the paper can be accurately guided and processed from the forming groove 8 to the processing space 14 that cooperates with the forming disk 12, and each part can be accurately shaped.

[0038] Working process: When the paper corner protector is formed, the paper first enters the forming groove 8 of the forming shaft 7. As the shaft rotates, when it cooperates with the corresponding forming disk 12, the paper can seamlessly transition from the forming groove 8 to the processing space 14 of the forming disk 12 due to the mutual adaptation of the cross-sectional shapes of the two. In this process, the forming wheel 13 further squeezes, bends, and performs other operations on the paper according to the adapted shape, so that the paper gradually completes the forming of the paper corner protector according to the predetermined specification shape. During the whole process, due to the adaptability of the shape, the paper will not have problems such as wrinkles, damage, or irregular forming due to shape mismatch.

[0039] By ensuring the adaptability of the cross-sectional shapes of the forming disc 12 and the forming groove 8, the smoothness and accuracy of the paper forming process are improved, the paper loss and forming errors during the processing are minimized, and the produced paper corner protectors are guaranteed to have standardized shapes and reliable quality, meet the requirements of corresponding specifications, and improve the product qualification rate.

[0040] Furthermore, the auxiliary disk 11 is conical, and the conical surfaces of the two auxiliary disks 11 are arranged opposite to each other.

[0041] In the above scheme, the auxiliary disk 11 is conical, and the conical surfaces of the two auxiliary disks 11 are arranged opposite to each other. The shape of the cone enables it to guide and gather the paper from different angles when assisting in the forming of the paper. The inclination angle of the conical surface and the smoothness of the surface are reasonably designed to facilitate the paper to fit into the forming groove 8 and gradually bend into a suitable shape along the guidance of the conical surface. At the same time, the two conical surfaces arranged opposite to each other can exert a uniform force on the paper from both sides to ensure the stability of the paper during the forming process.

[0042] Working process: When the paper enters the molding groove 8 of the molding shaft 7 and moves to the inside of the mounting frame 5, the conical auxiliary disks 11 arranged opposite to each other on both sides begin to play a role, and the paper is attached to the conical surface. With the rotation of the molding shaft 7 and the cooperation of the molding wheel 13, the conical surface guides the paper to bend along its shape, and at the same time, supports and limits the paper from both sides to avoid problems such as deviation and warping of the paper during the molding process, and assists the paper to successfully complete the molding operation in the molding groove 8. The design and relative arrangement of the conical auxiliary plate 11 can better assist the forming of paper in the forming groove 8, improve the regularity and stability of paper forming, reduce the forming quality problems caused by factors such as the unstable position of paper in the initial forming stage, and improve the overall appearance quality and structural strength of the paper corner protector.

[0043] Furthermore, it also includes a ring 16, which is slidably mounted on the fixed shaft 1201; one end of the telescopic rod 17 is hinged to the outer wall of the ring 16, and the other end is hinged to the outer wall of the forming disk 12; the roller ring 18 is mounted on the outer side of the fixed tube of the telescopic rod 17, and the roller ring 18 is located in the processing space 14.

[0044] In the above scheme, the sleeve 16 is slidably mounted on the fixed shaft 1201, and its inner diameter is adapted to the outer diameter of the fixed shaft 1201, and can slide smoothly on the fixed shaft 1201, and its sliding range can be limited by some limiting structures such as clamping rings, etc., to ensure that it plays a role in the appropriate position. One end of the telescopic rod 17 is hinged on the outer wall of the sleeve 16, and the other end is hinged on the outer wall of the forming disk 12. The telescopic rod 17 has a telescopic characteristic and can adaptively change its length according to the position changes such as the lifting and lowering of the forming disk 12, ensuring the stability of the connection between the sleeve 16 and the forming disk 12; the outer side of its fixed cylinder is sleeved with a roller ring 18, which can be made of a smooth and wear-resistant material, and is located in the processing space 14. It has a certain contact with the paper during the processing and plays an auxiliary role.

[0045] Working process: When the forming disc 12 is lifted, lowered, slid, or other position changes under the action of the adjusting member 1202, the telescopic rod 17 will be extended and retracted accordingly to adapt to the position change through the hinged relationship between the telescopic rod 17, the sleeve ring 16, and the forming disc 12, and the connection state will always be maintained. When the paper passes through the processing space 14 for forming, the roller ring 18 located in the processing space 14 will have a slight contact and rolling with the paper. On the one hand, it assists the paper to move and form better in the processing space 14, avoiding jams between the paper and other components, and on the other hand, it can also smooth and regularize the paper to improve the quality of paper forming.

[0046] The stability of the forming disc 12 during position change is enhanced, and the auxiliary effect of the roller ring 18 on the paper in the processing space 14 further improves the forming effect of the paper, making the paper smoother during the forming process, reducing forming defects caused by poor paper movement, etc., and helping to improve the appearance quality and dimensional accuracy of the paper corner protector.

[0047] Furthermore, it also includes fastening bolts 15 which are detachably arranged on the circumferential side wall of the auxiliary disk 11 , and the fastening bolts 15 are used to fix the auxiliary disk 11 on the forming shaft 7 .

[0048] In the above scheme, the fastening bolt 15 is detachably arranged on the circumferential side wall of the auxiliary disk 11, and a threaded hole compatible with the fastening bolt 15 is opened on the auxiliary disk 11. The head of the fastening bolt 15 is convenient for the operator to use tools to tighten or loosen the bolt, and the screw part can be firmly screwed into the threaded hole to tightly fix the auxiliary disk 11 on the forming shaft 7, ensuring that the auxiliary disk 11 will not loosen or shift during the operation of the equipment, thereby ensuring that it can stably assist in paper forming.

[0049] When installing the auxiliary disk 11, the operator sets the auxiliary disk 11 on the appropriate position of the forming shaft 7, and then uses a tool such as a wrench to screw the fastening bolts 15 into the threaded holes of the auxiliary disk 11 in turn, and tightens the bolts to firmly fix the auxiliary disk 11 on the shaft; when the auxiliary disk 11 needs to be disassembled, repaired or replaced, the operation is reversed, and the fastening bolts 15 are loosened to remove the auxiliary disk 11 from the shaft. The operation is simple and convenient, and in the normal production process, the fastened auxiliary disk 11 can stably assist the forming of paper in the forming groove 8. The stability of the auxiliary disk 11 during the working process is guaranteed, and then its auxiliary effect on paper forming is guaranteed. At the same time, the installation, disassembly and maintenance of the auxiliary disk 11 are convenient, and the maintainability of the equipment and the reliability of the overall operation are improved.

[0050] Furthermore, it also includes a lifting adjustment plate 6 which is arranged on the frame 4 . The mounting frame 5 is arranged on the frame 4 through the lifting adjustment plate 6 . The lifting adjustment plate 6 is used to adjust the position of the mounting frame 5 .

[0051] In the above scheme, the lifting adjustment plate 6 is arranged on the frame 4, which has suitable structural strength and connection parts. The mounting frame 5 is connected to the frame 4 through the lifting adjustment plate 6. The lifting adjustment plate 6 can adopt a common height-adjustable structural form such as a screw lifting mechanism, a hydraulic lifting mechanism, etc. By operating related adjustment components such as the rotating handle of the screw, the control valve of the hydraulic system, etc., the vertical position of the mounting frame 5 relative to the frame 4 can be changed.

[0052] Working process: When the height position of the forming mechanism 2 needs to be adjusted as a whole, for example, to adapt to different paper feeding heights or to better connect with other supporting equipment, the operator operates the adjustment component of the lifting and adjusting plate 6. If it is a screw lifting mechanism, turn the rotating handle, and the screw drives the lifting and adjusting plate 6 and the mounting frame 5 installed thereon to perform lifting and lowering movements. After adjusting the mounting frame 5 to a suitable height position, fix the corresponding locking device such as the screw nut locking, so that the mounting frame 5 is stable in this position, ensuring that the subsequent parts of the forming mechanism 2 can work together normally to produce paper corner protectors. It facilitates the adjustment of the height position of the entire forming mechanism 2, improves the flexibility of the corner protector to cooperate with different production environments and upstream and downstream equipment, further enhances the versatility and adaptability of the equipment, and helps to optimize the entire production process and improve production efficiency.

[0053] Furthermore, it also includes a cutting piece 3 having a cutting hole, the shape of the cutting hole is the same as the shape of the formed paper corner protector, and the cutting piece 3 is used to cut the formed paper corner protector into segments.

[0054] In the above scheme, the cutting piece 3 has a cutting hole, whose shape is exactly the same as the shape of the formed paper corner protector. The cutting piece 3 can be made of sharp metal material. It is installed at a suitable position on the conveying path after the paper corner protector is formed, and can be equipped with a corresponding driving device such as an electric push rod to drive it to perform cutting action, etc., to ensure that the continuously formed paper corner protector can be accurately cut and segmented.
