Description

Technical Field

[0001] The utility model relates to the technical field of blade processing, in particular to a utility knife blade packaging device. Background Art

[0002] The utility knife blade dispensing device is usually used in the utility knife blade industrial production line. The utility knife blade dispensing device is an automated mechanical device used for dispensing utility knife blades to improve the dispensing efficiency of utility knives, reduce the operation of manual dispensing of utility knives, improve the accuracy of blade dispensing, and reduce human errors in the dispensing process;

[0003] The production process of the utility knife is usually to pull the raw metal coil to form a metal strip, and then make the metal strip go through grinding, forming, heat treatment and other processes in sequence, so that the metal strip has the properties required for the utility knife, and finally drive the metal strip to a punching and shearing machine, and the punching and shearing machine cuts the metal strip to form a number of small blades, and finally the small blades are divided into a storage box for storing blades;

[0004] In the existing utility knife production line, the storage box is clamped by a packing device, and the packing device makes the opening of the storage box face the punching shearing machine. The metal strip is sheared by the punching shearing machine to form a blade. The driving mechanism for delivery on the punching shearing machine throws the blade into the storage box. When the number of blades in the storage box reaches the set number, the electric disc on the packing device drives the storage box to rotate, so that the storage box with the loaded blades is away from the punching shearing machine, and the opening of the empty storage box is driven to approach and face the punching shearing machine, so as to realize the quantitative packing of the blades into the storage box;

[0005] When the electric disc of the blade packaging device drives the storage box containing the blades to rotate, the blades in the storage box will be affected by centrifugal force, so that the blades are at risk of being thrown out through the opening of the storage box. However, since the existing packaging device does not have a mechanism to prevent the blades from being thrown out at the opening of the storage box, when the storage box rotates, it is necessary to pay attention to whether the blades are thrown out. If the thrown blades are not dealt with in time, it will affect the safety of the workshop personnel and secondly will also reduce the packaging quality of the storage box. In order to overcome the above-mentioned defects, it is necessary to improve the existing packaging device. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the attached Figure 1-12 The utility model is further described with examples.

[0033] Embodiment 1: This embodiment discloses a utility knife blade packaging device.

[0034] Reference Figure 1-10After the blades are packed into the storage box 46 on the blade packing device, the electric disc 41 of the packing device drives the storage box 46 to rotate. In order to facilitate the placement of the blades, the opening of the storage box 46 is set to face outward, so that the blades in the storage box 46 are subjected to the centrifugal force caused by the rotation, and the blades are thrown out from the opening of the storage box 46. In order to solve the above problem, a utility knife blade packing device of this example includes a base 1, a clamping assembly 12, an electric disc 41, and a clamping assembly 1 2 comprises a cylinder 13, a magnetic member 14, and a long-mouthed clamp 21 for clamping a storage box 46, an electric disc 41 is assembled on the top wall of the base 1, a fixed end of the cylinder 13 is connected to the electric disc 41, a movable end of the cylinder 13 is connected to the long-mouthed clamp 21, a top wall protrusion of the electric disc 41 is provided with a rotating bar 42, the magnetic member 14 is provided with a rotating hole 18, the magnetic member 14 is hinged to the electric disc 41 through the rotating hole 18, a first magnetic portion 30 is provided on the axial side of the long-mouthed clamp 21 away from the electric disc 41, and the cylinder 13 is connected to the electric disc 41. The cylinder 13 drives the long nozzle clamp 21 to retract inward and the magnetic member 14 is attracted to the first magnetic portion 30, so that the magnetic member 14 abuts against the opening of the storage box 46, connecting the storage box 46 with the long nozzle clamp 21, that is, the clamp arm of the long nozzle clamp 21 stores the box 46, and the opening of the storage box 46 is located within the clamp arm of the long nozzle clamp 21. The cylinder 13 drives the storage box 46 to move outward by driving the long nozzle clamp 21, and then the blade is loaded into the storage box 46. After the blade is loaded, the cylinder 13 drives the long nozzle clamp 21 to move outward. The clamp 21 contracts. When the long-mouth clamp 21 contracts, the magnetic piece 14 is attracted to the first magnetic portion 30 of the long-mouth clamp 21, thereby driving the magnetic piece 14 to rotate, so that the magnetic piece 14 abuts against the opening of the storage box 46. Then, when the electric disc 41 rotates and drives the storage box 46 to rotate, even if the blade in the storage box 46 is affected by the centrifugal force, it will be blocked by the magnetic piece 14 at the opening of the storage box 46 during the outward movement, thereby reducing the possibility of the blade being thrown off due to the centrifugal force.

[0035] When it is necessary to open the long-mouth clip 21 and clamp the storage box 46 on the long-mouth clip 21, it is necessary to pry the long-mouth clip 21 apart, and the prying apart process is relatively inconvenient. In order to solve the above-mentioned problem, the long-mouth clip 21 of this embodiment includes an upper clamping arm 22, a lower clamping arm 23, and a spring 29. The spring 29 is a compression spring. The upper clamping arm 22 is rotatably connected with the lower clamping arm 23 through a first rotating shaft 24. The first rotating shaft 24 is parallel to the clamping surface of the upper clamping arm 22. The upper clamping arm 22 is provided with an upper extension arm 27, and the lower clamping arm 23 is provided with a lower extension arm 25. The extension direction of the upper extension arm 27 and the lower extension arm 23 are 5 are all extending in a direction perpendicular to the first rotating shaft 24, the spring 29 is connected to the top surface of the upper extension arm 27 and the bottom surface of the lower extension arm 25, and by setting the upper extension arm 27 and the lower extension arm 25, the technician can open the long mouth clamp 21 by pressing the upper extension arm 27 and the lower extension arm 25, thereby increasing the opening pressing portion of the long mouth clamp 21, and the technician can open the long mouth clamp 21 by pressing the upper extension arm 27 and the lower extension arm 25, thereby clamping the storage box 46 on the long mouth clamp 21, thereby improving the convenience of the technician in clamping the storage box 46 on the long mouth clamp 21.

[0036] In order to further improve the position stability of the spring 29 and reduce the risk of the spring 29 being misplaced, the top surface protrusion of the lower extension arm 25 of this embodiment is provided with an assembly strip 26, and the upper extension arm 27 is provided with a vertical assembly hole. The assembly strip 26 is passed through the assembly hole, and the spring 29 is sleeved on the assembly strip 26 and is located between the upper extension arm 27 and the lower extension arm 25. By sleeved the spring 29 on the assembly strip 26, the assembly strip 26 can limit the position of the spring 29 and reduce the risk of the spring 29 being misplaced, thereby improving the stability of the elastic performance of the long mouth clamp 21, thereby improving the stability of the long mouth clamp 21 clamping the storage box 46.

[0037] When the cylinder 13 drives the long-mouth clamp 21 to be in a retracted state, the magnetic piece 14 is located at the opening of the long-mouth clamp 21. Therefore, when the cylinder 13 drives the long-mouth clamp 21 to extend outward, the long-mouth clamp 21 will generate an impact force with the magnetic piece 14, thereby driving the magnetic piece 14 to rotate. If the magnetic piece 14 rotates at an angle that is too large, the magnetic piece 14 will be flipped, thereby causing the magnetic piece 14 to lose the function of abutting against the opening of the storage box 46. In order to solve the above problem, the long-mouth clamp 21 is parallel to the radial direction of the electric disc 11. A second magnetic part 31 is provided on the side, and the second magnetic part 31 is arranged toward the magnetic part 14. When the long nozzle clamp 21 extends outward, due to the effect of magnetic force, the magnetic part 14 and the second magnetic part 31 are attracted to each other. Because the cylinder 13 drives the long nozzle clamp 21 to extend, the long nozzle clamp 21 and the magnetic part 14 generate an impact force. After the impact force drives the magnetic part 14 to rotate, due to the magnetic attraction of the first magnetic part 30 and the second magnetic part 31 on the magnetic part 14, the magnetic part 14 rotates toward the long nozzle clamp 21, thereby reducing the possibility of the magnetic part 14 flipping over.

[0038] In order to further reduce the possibility of flipping of the magnetic part 14, the top surface protrusion of the electric disc 41 of the present embodiment is provided with an abutment portion 43, and the abutment portion 43 is used to prevent the magnetic part 14 from flipping. The abutment portion 43 is located on one side of the magnetic part 14 and on the rotation path of the magnetic part 14. When the magnetic part 14 rotates in the flipping direction, it will abut against the abutment portion 43 during the rotation process, thereby preventing the magnetic part 14 from flipping, so that the magnetic part 14 can complete the function of abutting with the storage box 46, thereby improving the stability of the clamping assembly 12 and further reducing the possibility of the blade being thrown off.

[0039] Since the magnetic part 14 only needs to have a magnetic attraction effect on the side facing the long mouth clamp 21 to achieve the effect of the magnetic part 14 abutting against the storage box 46, in order to save the cost of the equipment, the magnetic part 14 of this embodiment includes a rotating block 15 and a magnet 17. A rotating hole 18 is provided on the rotating block 15. The rotating block 15 is hinged to the electric disc 41 through the rotating hole 18. A groove is provided on the side of the rotating block 15 facing the long mouth clamp 21, and the magnet 17 is embedded in the groove. While retaining the magnetic function of the magnetic part 14, the cost required for the magnetic part 14 is saved, thereby saving the cost of the equipment.

[0040] When there is no storage box 46 located on the long-mouth clamp 21, since the upper clamp arm 22 and the lower clamp arm 23 of the long-mouth clamp 21 are in a closed state, the outward ends of the upper clamp arm 22 and the lower clamp arm 23 are in a fitted state, thereby increasing the difficulty of prying open the opening of the long-mouth clamp 21. In order to solve the above problem, the top surface of the lower clamp arm 23 of this embodiment is provided with a first through groove 32, and the storage box 46 is clamped in the first through groove 32. The axial direction of the first through groove 32 is parallel to the radial direction of the electric disc 41. When the upper clamp arm 22 and the lower clamp arm 23 are in a fitted state, the storage box 46 is clamped in the first through groove 32. The axial direction of the first through groove 32 is parallel to the radial direction of the electric disc 41. In the closed state, due to the provision of the first through slot 32, the upper clamp arm 22 and the lower clamp arm 23 are fitted together on the two side walls of the first through slot 32, so that the upper clamp arm 22 and the lower clamp arm 23 form a gap in the first through slot 32. The technician pries open the long-mouth clamp 21 through the upper extension arm 27 and the lower extension arm 25, and then assists in prying open the long-mouth clamp 21 through the gap of the first through slot 32, thereby improving the convenience of the technician in prying open the long-mouth clamp 21. At the same time, the first through slot 32 limits the storage box 46, thereby improving the stability of the storage box 46.

[0041] In order to reduce the volume occupied by the clamping assembly 12, a long groove 44 is opened on the top surface of the electric disc 41, the fixed end of the cylinder 13 is connected to the inner side of the long groove 44, and the bottom surface of the lower clamping arm 23 is protruded with a connecting portion 45, and the connecting portion 45 is slidably set in the long groove 44. The movable end of the cylinder 13 drives the long mouth clamp 21 to slide through the connecting portion 45, and the connecting portion 45 is slidably set in the long groove 44 along the radial direction of the electric disc 41. By embedding the cylinder 13 in the long groove 44, the volume occupied by the clamping assembly 12 is reduced, and the overall volume occupied by the packaging device is reduced.

[0042] The clamping components 12 are arranged in one group or multiple groups. When multiple groups are arranged, the clamping components 12 are arranged in a circular array on the top surface of the electric disc 41. By arranging multiple groups of clamping components 12, the packaging efficiency of the packaging device is improved.

[0043] The electric disc 41 includes a driving motor 48 and a disc 49. An assembly groove 47 is provided on the bottom surface of the base 1. The disc 49 is rotatably connected to the top surface of the base 1. The fixed end of the driving motor 48 is connected to the inner side surface or the inner bottom surface of the assembly groove 47. The rotating end of the driving motor 48 is connected to the disc 49. Through the above-mentioned arrangement, the driving motor 48 is assembled on the inner wall of the assembly groove 47, reducing the volume occupied by the electric disc 41, thereby further reducing the space occupied by the packaging device.

[0044] Example 2: Figure 11-12 As shown, a method for packaging utility knife blades includes a utility knife blade packaging device of Example 1 and a punching and shearing machine 50. A metal strip 51 that has been ground, formed, and heat-treated is cut on the punching and shearing machine 50 to form a plurality of groups of utility knife blades. The punching and shearing machine 50 then drives the utility knife blades toward the utility knife blade packaging device to allow the utility knife blades to enter a storage box 46. When the number of utility knife blades in the storage box 46 reaches a set number, the electric disc 41 drives the storage box 46 to rotate, allowing the utility knife blades to be stored in the next group of empty storage boxes 46.

[0045] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
