Description

Technical Field

[0001] This utility model belongs to the field of scissor blade manufacturing technology, specifically relating to a scissor blade straightening mechanism. Background Technology

[0002] In the manufacturing process of shear blades, straightening is a crucial step, aimed at ensuring that the straightness and shape of the shear blades meet product quality requirements. In traditional shear blade straightening processes, the discharge and subsequent processing of the shear blades after the straightening machine completes the straightening operation is relatively simple but presents numerous problems.

[0003] Existing straightening machines typically guide material directly through inclined guide troughs. In this method, the shear blades, lacking an effective sorting and straightening mechanism, exhibit inconsistent blade orientation as they pass through the trough, resulting in chaotic blade and handle orientations and an inability to form a neat and orderly arrangement. After feeding, the disordered state of the shear blades necessitates manual sorting and storage. Manual operation is not only inefficient and increases labor costs, but also prone to irregular sorting and untidy arrangement, causing significant inconvenience for subsequent storage and retrieval. Furthermore, manual operation struggles to guarantee consistency and stability in each sorting process, ultimately impacting overall product quality and production efficiency.

[0004] With the continuous expansion of scissor blade production scale and the increasing demands for product quality, traditional straightening machine discharge and processing methods can no longer meet the needs of modern production. Therefore, it is particularly urgent to develop a straightening mechanism that can automatically sort, neatly arrange, and efficiently store scissor blades. Utility Model Content

[0005] The present invention aims to solve the technical problem that in the existing straightening machine, the material is directly guided by the inclined guide groove, which cannot effectively sort the shear blades. After the material is discharged, it needs to be manually sorted and stored, which not only consumes a lot of time and manpower, but also has a high labor intensity and affects production efficiency.

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

[0007] A shear blade straightening mechanism, comprising:

[0008] The feeding guide chute is used to receive the shear blades from the discharge port of the straightening machine and comb the shear blades into a vertical position with the blades facing forward and the handles facing backward.

[0009] The positioning box is used to receive the shear blades pushed out by the cylinder from the discharge port of the feeding guide chute. The shear blades coming out of the discharge port are neatly arranged in the U-shaped groove of the positioning box.

[0010] The positioning slot is used to guide and position the positioning box or to pull out the positioning box.

[0011] Preferably, there are two feeding guides, which are symmetrically arranged on the rear side of the discharge roller on the straightening machine. The feeding guides include an inclined V-shaped guide and a horizontally arranged discharge trough connected to the end of the V-shaped guide. The discharge port is located on the outer side of the discharge trough.

[0012] Preferably, the piston rod end of the cylinder is fixedly connected to a push plate that extends into the discharge trough and does not affect the vertical arrangement of the shear blades. The cylinder action pushes the push plate to pass the shear blades in the discharge trough through the discharge port and push them into the U-shaped trough.

[0013] Preferably, a limiting plate is provided inside the U-shaped groove. The top of the limiting plate cooperates with the guide groove A on the top of the U-shaped groove for limiting and guiding sliding, and the bottom of the limiting plate cooperates with the guide groove B opened on the bottom wall of the U-shaped groove for limiting and guiding sliding.

[0014] Preferably, a bendable straight steel wire passes through the positioning box and extends into the U-shaped groove through the limiting plate. When the scissor blades are arranged in the U-shaped groove, the straight steel wire is inserted into the positioning hole on the scissor blades.

[0015] Preferably, after the positioning box is inserted into the positioning groove, the inner end face of the positioning box abuts against the outer surface of the discharge groove, and the front and rear ends of the positioning groove are threaded with limit blocks that lock and fix the positioning box in the positioning groove and abut against the discharge groove.

[0016] Preferably, the material guide chute is installed on the support base, and the cylinder is also installed on the support base.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] The shear blade straightening mechanism places the shear blades with the handle facing backward on a conveyor belt, which then transports them to a straightening machine for straightening. The straightened shear blades enter the discharge guide chute from the straightening machine's outlet. The inclined V-shaped guide chute utilizes gravity to allow the shear blades to slide down, with the V-shaped structure guiding and limiting them, transforming the shear blades from a horizontal position to a vertical position with the blade facing forward and the handle facing backward, and allowing them to enter the horizontal discharge chute in an orderly manner. A cylinder mounted on a support base actuates, and a pusher plate at the end of its piston rod pushes the vertically arranged shear blades through the discharge port into the U-shaped groove of the positioning box. A bendable straight steel wire on the positioning box passes through a limiting plate and extends into the U-shaped groove. When the shear blades are arranged, the straight steel wire inserts into its positioning hole to position the shear blades. Simultaneously, the limiting plate in the U-shaped groove, through cooperation with guide grooves A and B, slides and limits the shear blades within the U-shaped groove, ensuring that the shear blades are stacked neatly. The positioning box is accurately inserted into the positioning slot through the guide insertion positioning function, with its inner end face abutting against the outer surface of the discharge chute. The limiting blocks at both ends of the positioning slot lock and fix the positioning box to prevent it from moving or shaking during operation. After the scissor blades are neatly stacked in the U-shaped groove, release the limiting blocks from restricting the positioning box, remove the positioning box along with the scissor blades, pull the straight steel wire to detach it from the limiting plate and the positioning box, and then bend both ends of the straight steel wire upwards to neatly arrange the scissor blades on the straight steel wire.

[0019] The entire operation process automates the straightening, cutting, arranging, and storage of the scissor blades, reducing manual intervention. Through the collaborative work of various components, the straightening and arranging of the scissor blades can be completed quickly and accurately, greatly improving work efficiency compared to traditional manual operation. The cutting guide groove can arrange the scissor blades into an upright position with the blade facing forward and the handle facing backward, laying the foundation for neat arrangement and helping to improve the standardization of subsequent processes.

[0020] The straight steel wire not only positions the scissor blades within the positioning box, but also serves as a carrier during organization and storage, transferring the neatly arranged scissor blades onto the straight steel wire for convenient centralized organization and storage.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following combination Figures 1 to 7 This application will be described in further detail.

[0031] This application discloses a shear blade straightening mechanism, including a feeding guide groove 1, a positioning box 4, and a positioning groove 6;

[0032] The feeding guide 1 is used to receive the shear blades 3 from the discharge port of the straightener 2 and comb the shear blades 3 into a vertical position with the blade facing forward and the handle facing backward. The feeding guide 1 has two sections, which are symmetrically arranged on the rear side of the discharge roller 7 on the straightener 2. The feeding guide 1 includes an inclined V-shaped guide 101 and a horizontally arranged discharge trough 102 connected to the end of the V-shaped guide 101. The discharge port 103 is located on the outer side of the discharge trough 102.

[0033] The feeding guide chute 1 receives the shear blades 3 from the discharge port of the straightening machine 2 and arranges them into a vertical position with the blades facing forward and the handles facing backward. This arrangement function helps subsequent processes to neatly arrange and process the shear blades 3, improving the standardization and efficiency of the work.

[0034] The design employs a combination of an inclined V-shaped guide trough 101 and a horizontal discharge trough 102. The inclined V-shaped guide trough 101 utilizes gravity to allow the shear blade 3 to slide smoothly down, while the V-shaped structure provides guidance and restraint for the shear blade 3, ensuring that it can transition from a horizontal to a vertical position and enter the discharge trough 102 in an orderly manner. The horizontal discharge trough 102 provides a stable platform for the subsequent cylinder 8 to push the shear blade 3.

[0035] The feeding guide trough 1 has two symmetrically arranged on the rear side of the discharge roller 7 on the straightening machine 2. This symmetrical design can evenly distribute the straightened shear blades 3 into the two feeding guide troughs 1, improving the overall working efficiency and avoiding the congestion problem that may occur in a single guide trough.

[0036] The positioning box 4 is used to receive the shear blades 3 pushed out by the cylinder 8 from the discharge port 103 of the feeding guide 1. The shear blades 3 from the discharge port 103 are neatly arranged in the U-shaped groove 5 of the positioning box 4. The feeding guide 1 is installed on the support base 16, and the cylinder 8 is also installed on the support base 16. The piston rod end of the cylinder 8 is fixedly connected to a push plate 9 that extends into the discharge trough 102 and does not affect the vertical arrangement of the shear blades 3. When the cylinder 8 moves, it pushes the push plate 9 to push the shear blades 3 in the discharge trough 102 through the discharge port 103 and into the U-shaped groove 5.

[0037] A limiting plate 10 is provided inside the U-shaped groove 5. The top end of the limiting plate 10 cooperates with the guide groove A11 on the top of the U-shaped groove 5 for limiting and guiding sliding. The bottom end of the limiting plate 10 cooperates with the guide groove B12 opened on the bottom wall of the U-shaped groove 5 for limiting and guiding sliding.

[0038] A bendable straight steel wire 13, through which a through-limiting plate 10 extends into a U-shaped groove 5, passes through the positioning box 4. When the scissor blades 3 are arranged in the U-shaped groove 5, the straight steel wire 13 is inserted into the positioning hole 14 on the scissor blades 3.

[0039] The U-shaped groove 5 of the positioning box 4 can receive the scissor blades 3 pushed out from the discharge port 103 of the feeding guide 1, and keep the scissor blades 3 neatly arranged there. This helps to centrally manage the scissor blades 3 and carry out subsequent sorting and storage work, avoiding the scissor blades 3 from becoming messy and colliding with each other during storage.

[0040] A limiting plate 10 is provided inside the U-shaped groove 5. The top end of the limiting plate 10 cooperates with the guide groove A11 on the top of the U-shaped groove 5, and the bottom end cooperates with the guide groove B12 opened on the bottom wall of the U-shaped groove 5. This design allows the limiting plate 10 to slide within the U-shaped groove 5, ensuring that the scissor blades 3 always maintain a neat arrangement during the stacking process, further improving the accuracy and stability of the arrangement.

[0041] A flexible straight steel wire 13 passes through the positioning box 4. When the scissor blades 3 are arranged in the U-shaped groove 5, the straight steel wire 13 is inserted into the positioning hole 14 on the scissor blades 3. The straight steel wire 13 not only positions the scissor blades 3, ensuring their accurate relative position in the U-shaped groove 5, but also serves as a carrier for transferring the neatly arranged scissor blades 3 to the straight steel wire 13 during subsequent organization and storage, facilitating centralized organization and storage.

[0042] The positioning slot 6 is used to guide and position the positioning box 4 or to pull out the positioning box 4.

[0043] After the positioning box 4 is inserted into the positioning groove 6, the inner end face of the positioning box 4 abuts against the outer surface of the discharge groove 102. The front and rear ends of the positioning groove 6 are threaded with limit blocks 15 that lock and fix the positioning box 4 in the positioning groove 6 and abut against the discharge groove 102.

[0044] The positioning slot 6 is used to guide and position the positioning box 4 or to pull it out. The guide and insertion positioning function allows the positioning box 4 to be accurately inserted into the positioning slot 6, ensuring that the positioning box 4 is aligned with the discharge port 103 of the feeding guide channel 1, and ensuring that the scissor blades 3 can be smoothly pushed from the discharge channel 102 into the U-shaped groove 5 of the positioning box 4; while the pull-out function makes it convenient to remove the positioning box 4 together with the scissor blades 3 after the scissor blades 3 are neatly stacked.

[0045] The front and rear ends of the positioning groove 6 are threadedly connected to limit blocks 15, which can lock and fix the positioning box 4 in the positioning groove 6 and abut against the discharge chute 102. This design can prevent the positioning box 4 from moving or shaking during operation, ensuring the stability and accuracy of the shear blade 3 pushing process.

[0046] During operation, the shear blade 3 is placed on the conveyor belt with the handle facing backward. It is then conveyed to the straightening machine 2. After straightening by the straightening machine 2, it is discharged into the discharge guide trough 1. Guided by the V-shaped guide trough 101 and the discharge trough 102, the shear blade 3 is positioned vertically in the discharge trough 102 with the blade facing forward and the handle facing backward. The cylinder 8 actuates to push the push plate 9, which pushes the shear blade 3 through the discharge port 103 into the U-shaped trough 5. The positioning hole 14 on the shear blade 3 mates with the straight steel... The wire 13 is inserted for positioning, allowing the scissor blades 3 to be neatly stacked and placed in the U-shaped groove 5, abutting against the limiting plate 10. When organizing and storing the neatly stacked scissor blades 3, first release the limiting block 15 from the positioning box 4, then remove the positioning box 4 along with the scissor blades 3. Pull out the straight wire 13 to detach it from the limiting plate 10 and the positioning box 4, and bend both ends of the straight wire 13 upwards, arranging the scissor blades 3 neatly on the straight wire 13 (as shown in the attached diagram). Figure 7 (As shown).

[0047] The entire operation process automates the straightening, feeding, arranging, and storage of the shear blades 3, reducing manual intervention and improving work efficiency. Through the coordinated operation of components such as the conveyor belt, straightening machine 2, feeding guide chute 1, cylinder 8, and positioning box 4, the straightening and sorting of the shear blades 3 can be completed quickly and accurately. This ensures that the shear blades 3 are neatly stacked in the U-shaped trough 5 and ultimately neatly arranged on the straight steel wire 13. This neat storage method not only facilitates the storage and management of the shear blades 3 but also allows for quick and convenient retrieval when needed, improving work efficiency. It exhibits good repeatability and stability, ensuring that the shear blades 3 are straightened and sorted in the same way each time, guaranteeing product quality and consistency. Furthermore, the positioning of the straight steel wire 13 and the guiding effect of the limiting plate 10 further enhance the stability and accuracy of the operation.
