Description

Technical Field

[0001] This utility model relates to the technical field of fishhook processing equipment, specifically to a fishhook flattening machine. Background Technology

[0002] Currently, to increase the strength of fishhooks, the hook bend is typically flattened. Existing fishhook flattening machines include vibration feeding, material sorting, material release, material pushing, and flattening operations. The material pushing action comprises two movements: forward and backward. These two movements are driven by two face cams and a roller located between them. This drive method requires high installation precision, making installation difficult. Furthermore, the pressure transmission between the two face cams and the rollers causes wear on the meshing path, resulting in inaccurate forward and backward positioning, i.e., inaccurate material pushing displacement.

[0017] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Please see Figures 1 to 4 A fishhook flattening machine provided in one embodiment of the present invention includes a frame 11, a cam drive assembly 12 disposed on the frame 11, and a drive motor 13 disposed on the side of the frame 11. The frame 11 is sequentially provided with a vibrating feeding assembly 14, a dispensing assembly 15, a feeding assembly 16, a pushing assembly 17, and a flattening assembly 18. The dispensing assembly 15, the feeding assembly 16, and the pushing assembly 17 are all meshed with the cam drive assembly 12. The drive motor 13 is sequentially connected to the flattening assembly 18 and the cam drive assembly 12 through a transmission assembly 19. The feeding assembly 17 includes a first sliding assembly 171 connected to the feeding drive cam 121 in the cam drive assembly 12, a rotating assembly 172 connected to the first sliding assembly 171, a second sliding assembly 173 connected to the rotating assembly 172, and a feeding plate 174 installed on the movable end of the second sliding assembly 173. The second sliding component 173 is provided with an elastic telescopic component 175. The movable end of the elastic telescopic component 175 is connected to the movable end of the second sliding component 173. When the pusher plate 174 completes the pushing action, the elastic telescopic component 175, under the action of its own restoring force, drives the movable end of the second sliding component 173 and the pusher plate 174 to retract.

[0020] It should be noted that in the flattening process of this utility model, the fish hook to be flattened is first transmitted from the vibrating plate 141 to the vibrating inclined plate 142 by the vibrating feeding component 14. Then, under the drive of the cam drive component 12, the material distribution component 15 performs intermittent up and down movement, distributing one fish hook to be flattened each time (because the gap between the end of the vibrating inclined plate 142 and the material distribution plate 161 of the material distribution component 16 can only accommodate one fish hook to be flattened). Driven by the cam drive assembly 12, the end of the feeding plate 161 of the feeding assembly 16 moves away from the vibrating inclined plate 142, and the flattened fish hook falls onto the material rack horizontal plate 111 (the material rack horizontal plate 111 is located at the bottom of the vibrating inclined plate 142), and returns to the original position to stop the material. Driven by the cam drive assembly 12, the pusher plate 174 moves along the material rack horizontal plate 111 (the pusher plate 174 is located between the two material rack horizontal plates 111) to push the fish hook to be flattened into the flattening station. After the pusher plate 174 completes the pushing action, the elastic telescopic component 175, under the action of its own restoring force, drives the movable end of the second sliding component 173 and the pusher plate 174 to retract. At the same time, the flattening component 18 performs a flattening operation under the drive of the drive motor 13.

[0021] Please see Figure 1 and Figure 2 In a preferred embodiment of this utility model, the vibratory feeding assembly 14 includes a vibratory plate 141 mounted on the frame 11, a vibratory ramp 142 connected to the vibratory plate 141, and an electric vibrator 143 mounted on the frame 11 and used to support the vibratory ramp 141. The electric vibrator 143 causes the vibratory ramp 141 to vibrate for feeding. This electrically adjustable vibration method replaces the existing mechanical impact vibration method, thereby improving accuracy and reducing component damage.

[0022] Please see Figures 1 to 4 In a preferred embodiment of the present invention, the second sliding component 173 includes a second support block 1731 disposed on the frame 11, a second slide rail 1732 disposed on the second support block 1731, and a second slider 1733 disposed on the second slide rail 1732. The pusher plate 174 is installed on the top of one end of the second slider 1733, and two sets of second rollers 1734 are installed on the top of the other end. One end of the rotating component 172 is movably locked between the two sets of second rollers 1734, so that the rotating component 172 can slide between the two sets of second rollers 1734 during rotation, thereby driving the second slider 1733 to slide on the second slide rail 1732, that is, realizing the pusher plate 174 to move forward and backward.

[0023] Please see Figures 1 to 4 In a preferred embodiment of the present invention, the elastic telescopic component 175 includes a first bolt 1751 mounted on the second support block 1731, a second bolt 1752 mounted on the second slider 1733, and a spring 1753 connecting the first bolt 1751 and the second bolt 1752.

[0024] It should be noted that during the pushing process, i.e. the pushing stroke of the pushing drive cam 121, the movable end of the spring 1753 moves forward with the second slider 1733, and the spring 1753 is stretched. During the retraction process, i.e. the return stroke of the pushing cam 121, the spring 1753 automatically contracts under the action of its own restoring force, driving the movable end of the second sliding component 173 and the pushing plate 174 to retract.

[0025] Please see Figures 1 to 4 In a preferred embodiment of the present invention, the rotating assembly 172 includes a base 1721 mounted on the frame 11 and a rotating cylinder 1722 rotatably mounted on the base 1721. The outer wall of the rotating drum 1722 is provided with a first rotating arm 1723 and a second rotating arm 1724. The first rotating arm 1723 is rotatably connected to the first sliding assembly 171, and the end of the second rotating arm 1724 is movably locked between two sets of second rollers 1734 to avoid interference during the rotation of the rotating drum 1722.

[0026] Please see Figures 1 to 4 In a preferred embodiment of the present invention, the first sliding component 171 includes a first support block 1711 disposed on the frame 11, a first slide rail 1712 disposed on the first support block 1711, and a first slider 1713 disposed on the first slide rail 1712. The first slider 1713 is rotatably connected to a first connecting block 1714 at one end near the rotating assembly 172, and the other end of the first connecting block 1714 is rotatably connected to the first rotating arm 1723. The first slider 1713 has a second connecting block 1715 at one end near the cam drive assembly 12. The second connecting block 1715 has a drive roller 1716 at one end near the rotating assembly 172. The drive roller 1716 is in close contact with the pusher drive cam 121 in the cam drive assembly 12.

[0027] It should be noted that during the feeding process, that is, during the pushing stroke of the feeding drive cam 121, the first slider 1713 slides forward, driving the first connecting block 1714 to rotate. At the same time, the first connecting block 1714 drives the rotating drum 1722 to rotate through the first rotating arm 1723. The rotating drum 1722 drives the second rotating arm 1724 to rotate. The second rotating arm 1724 drives the second slider 1733 and the feeding plate 174 to move forward. During the retraction process, i.e. the return stroke of the pusher drive cam 121, the spring 1753 automatically contracts under its own restoring force, driving the second slider 1733 and the pusher plate 174 to retract. The second slider 1733 drives the rotating drum 172 to rotate through the second rotating arm 1724. The rotating drum 1722 drives the first slider 1713 to slide backward through the rotation of the first rotating arm 1723 and the first connecting block 1714.

[0028] Please see Figures 1 to 4 In a preferred embodiment of the present invention, a return roller 1717 is mounted on the end of the second connecting block 1715 away from the rotating assembly 172. When the spring 1753 breaks, the return roller 1717 is in close contact with the return drive cam 122 in the cam drive assembly 12. The return drive cam 122 and the push drive cam 121 are located on both sides of the second connecting block 1715, respectively.

[0029] It should be noted that when the spring 1753 breaks, since the pusher drive cam 121 is in the return stroke, there is no additional power to drive the pusher plate 174 to retract. Therefore, by adding the retraction roller 1717, and since the retraction drive cam 122 is in the push stroke, the pusher plate 174 can be driven to retract through the first sliding component 171, the rotating component 172, and the second sliding component 173, thus achieving the purpose of "safety".

[0030] Please see Figures 1 to 4 In a preferred embodiment of the present invention, the second connecting block 1715 has a U-shaped structure, and the driving roller 1716 and the retracting roller 1717 are respectively mounted on one U-shaped arm of the second connecting block 1715, so that the two can engage with the cam drive assembly 12 without interfering with each other.

[0031] Please see Figures 1 to 4 In a preferred embodiment of this utility model, the bottom of the pusher plate 174 is provided with two U-shaped grooves, which are bolted to the second slider 1733 to facilitate adjustment of the installation position.

[0032] Please see Figure 1 and Figure 2 In a preferred embodiment of the present invention, the transmission assembly 19 includes a first transition wheel assembly 191 installed at the bottom of the frame 11 and a second transition wheel assembly 192 installed on the flattening assembly 18; The first transition wheel assembly 191 is connected to the output end of the drive motor 13 and the second transition wheel assembly 192 via different belts. The second transition wheel assembly 192 is connected to the input end of the cam drive assembly 12 via different belts.

[0033] It should be noted that, in order to avoid transmission interference, both the first transition wheel assembly 191 and the second transition wheel assembly 192 contain two transition wheels, and each transition wheel is connected to the belt at the corresponding position.

[0034] In summary, this utility model automatically completes the pushing and retracting actions through the cooperation between the first sliding component 171, the rotating component 172, the second sliding component 173, the pusher plate 174, and the elastic telescopic component 175. Moreover, there is no pressure engagement during the driving process of the pusher drive cam 121, thereby reducing the wear of the drive engagement path during the pushing action and improving the accuracy of the pushing displacement.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
