Description

Technical Field

[0001] This utility model relates to the technical field of dovetail clip dipping equipment, and in particular to a dipping device for dovetail clips. Background Technology

[0002] A binder clip, also known as a long-tail clip, is a type of metal clip-on stationery. It is characterized by its good elasticity, rust resistance, and corrosion resistance. It is commonly used for organizing office documents. Its structure consists of a "V"-shaped clip body made of metal spring wire and spring handles at both ends. It generates elasticity through the principle of metal shape recovery and can be reused.

[0003] Traditionally, the production process of dovetail clips requires dipping them in paint. The surface treatment of the dovetail clips involves dipping them in materials such as paint, anti-rust coatings, or oxide layers to improve their corrosion resistance. Generally, a rack containing un-dipped dovetail clips is hung on a conveyor and moved. The conveyor then sends the rack into the paint dipping tank, where it is completely submerged, and then it is sent out. This reduces the amount of manual painting work.

[0004] However, during the varnishing process, some of the dovetail clips on the placement rack may accidentally fall into the varnishing tank. After prolonged use, they tend to accumulate in the varnishing tank, affecting the normal varnishing operation of the dovetail clips. For example, if they get stuck on the placement rack, the entire varnishing operation needs to be stopped when removing the fallen dovetail clips from the varnishing tank. Personnel then need to retrieve them using a net, which is labor-intensive and inconvenient. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a varnishing device for dovetail clips.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a varnishing device for dovetail clips, comprising a varnishing tank and a conveyor mounted thereon for moving a placement rack, wherein a guide plate is provided inside the varnishing tank directly below the conveyor, a guide platform is provided below the guide plate, a through hole is provided on the upper side of the guide platform directly below the guide plate, a base is provided at the through hole, a storage plate is provided on the base, a cylinder is provided directly below the guide platform, the top end of the piston rod of the cylinder is connected to the lower side of the base, a pusher plate is slidably provided below the guide plate along its length, an opening is provided on one side of the varnishing tank opposite to the pusher plate, and a sealing plate is provided at the opening.

[0024] like Figures 1 to 6 As shown, a varnishing apparatus for dovetail clips includes a varnishing tank 1 and a conveyor 3 disposed above it for moving a placement rack 2. Inside the varnishing tank 1, directly below the conveyor 3, is a V-shaped guide plate 4 with its opening 11 facing downwards. Below the guide plate 4 is a guide platform 5. In this embodiment, as... Figure 3 As shown, the left and right ends of the upper side of the guide platform 5 are inclined towards the middle. The purpose of this is to prevent the dovetail clip from staying on the guide plate 4 and the left and right ends of the guide platform 5 for too long.

[0025] A through hole 6 is provided on the upper side of the guide platform 5, directly below the guide plate 4. The length of the through hole 6 is smaller than the length of the guide platform 5. A base 7 is provided at the through hole 6, and a storage plate 8 is provided on the base 7. The length of the storage plate 8 is the same as the length of the guide platform 5. A cylinder 9 is vertically provided at the bottom of the paint impregnation tank 1, directly below the guide platform 5. The top of the piston rod of the cylinder 9 is connected to the lower middle part of the base 7. An isolation cover 18 is fixed at the bottom of the paint dipping tank 1, directly below the through hole 6. The isolation cover 18 encloses the cylinder 9 inside. Rectangular protective plates 19 are arranged opposite each other on the lower side of the base 7. The two sets of protective plates 19 are located at the left and right ends of the outer side of the isolation cover 18, and their length is the same as that of the isolation cover 18. A baffle plate 20 is fixed at the lower side of the left and right ends of the storage plate 8. The lower end of the baffle plate 20 passes through the guide platform 5. The length of the baffle plate 20 is the same as that of the guide platform 5. The purpose is that when the guide plate 4 is moved upward, the baffle plate 20 can block the dovetail clip located on the guide platform 5 but outside the guide plate 4 from flowing to the bottom of the guide plate 4.

[0026] Inside the impregnation tank 1, two partition plates 21 are fixedly mounted on the bottom side. These two partition plates 21 are located on opposite sides of the two sets of shielding plates 20, arranged along the length of the impregnation tank 1. The upper side of the partition plates 21 is connected to the lower side of the guide platform 5. Inside the isolation cover 18, a conveying pump 22 is installed. The input end of the conveying pump 22 is connected to a main pipe 23. The front end of the main pipe 23 extends through the isolation cover 18 and is located between the isolation cover 18 and the partition plates 21. A branch pipe 24 is also installed at the connection point between the main pipe 23 and the input end of the conveying pump 22. The front end of the branch pipe 24 passes through the base 7 and the receiving plate 8. The upper side is flush with the upper middle part of the storage plate 8. It should be noted that several groups of branch pipes 24 can be set and distributed sequentially along the length of the guide platform 5. The output end of the delivery pump 22 is connected to the output pipe 25. The front end of the output pipe 25 passes through the isolation cover 18, the partition plate 21 and the guide platform 5 in sequence. It is located above the guide platform 5 and outside the range of the storage plate 8. At the left end of the guide platform 5, a solenoid valve 26 is set on the branch pipe 24 and a check valve 27 is set on the output pipe 25. The purpose is to facilitate personnel to control the opening and closing of the branch pipe 24 and to prevent the backflow of liquid flowing in the output pipe 25.

[0027] like Figures 4 to 5 As shown, a push plate 10 is slidably disposed below the guide plate 4 along its length. The lower side of the push plate 10 can fit against the upper side of the storage plate 8. An opening 11 opposite to the push plate 10 is provided on the right side of the paint impregnation tank 1. The opening 11 is rectangular. A sealing plate 12 is provided at the opening 11. In this embodiment, a threaded hole (not shown in the figure) is provided on the outer wall of the paint impregnation tank 1. A bolt (not shown in the figure) is threaded through the sealing plate 12 and connected to the threaded hole. A sealing ring (not shown in the figure) is also embedded around the outside of the opening 11.

[0028] Motors 13 are arranged opposite each other on the lower side of guide plate 4. Protective covers 14 are provided on the outside of motors 13. The output shafts of the two sets of motors 13 each pass through one end of the protective cover 14 and are fitted with winding reels 15. Connecting ropes 16 are wound on the winding reels 15. The connecting ropes 16 on the two sets of winding reels 15 are respectively connected to the front and rear sides of the upper end of push plate 10. Guide rods 17 are arranged horizontally along the width direction on the left and right sides of the inner wall of the paint impregnation tank 1. The two sets of connecting ropes 16 pass through a set of guide rods 17 and are connected to push plate 10. In this embodiment, a sealed bearing is provided where the output shaft of motor 13 passes through the protective cover 14. The purpose is to prevent liquid in paint impregnation tank 1 from flowing into the interior of protective cover 14 through the gap where the output shaft of motor 13 passes through the protective cover 14. It should be noted that the main pipe 23 and branch pipe 24 and output pipe 25 of the delivery pump 22 are all provided with sealing rings and sealing caps at their respective passages to prevent leakage.

[0029] The placement rack 2 with dovetail clips is moved by the conveyor 3 and immersed one by one into the varnish dipping tank 1 for varnish dipping. Some dovetail clips fall out of the placement rack 2 due to the flow of liquid in the varnish dipping tank 1 or their own loose fixation and fall into the varnish dipping tank 1. Under the guidance of the guide plate 4 and the two ends of the guide table 5, they enter the storage plate 8.

[0030] When cleaning the dovetail clips that have fallen into the impregnation tank 1, first activate cylinder 9. Cylinder 9 pushes base 7, which in turn moves the collection plate 8 upward toward guide plate 4, so that the upper left and right ends of the collection plate 8 fit against the lower left and right ends of the guide plate 4. This prevents external liquid from flowing into the space between the collection plate 8 and the guide plate 4. Simultaneously, the delivery pump 22 will start. The solenoid valve 26 on the branch pipe 24 is in the closed state, so the liquid from the delivery pump 22 will not flow through the branch pipe 24. During the upward movement of the collection plate 8, some liquid will enter through the gap between the base 7 and the through hole 6. Outside the isolation cover 18, the main pipe 23 sucks up the internal liquid and discharges it into the space on the guide platform 5. When the upper side of the receiving plate 8 is attached to the lower side of the guide plate 4, the switch solenoid valve 26 is opened, and the branch pipe 24 begins to flow, which also begins to transport the liquid located between the guide plate 4 and the receiving plate 8 until it is emptied. Then, the two sets of motors 13 start to rotate forward, and the push plate 10 is pulled to move towards the opening 11. At this time, the sealing plate 12 is opened, and the dovetail clips on the receiving plate 8 are pushed out by the push plate 10 through the opening 11, without the need for personnel to manually reach into the paint dipping tank 1 to retrieve it.

[0031] It should be noted that personnel can start the process at regular intervals.

[0032] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
