[0007] As a preferred technical solution of this utility model, a connecting block is fixedly connected to the top right side of the cold heading machine body, and the right end of the connecting block extends into the interior of the top left side of the cleaning box and its outer surface is fixedly connected to the interior of the cleaning box.

[0008] As a preferred embodiment of this utility model, a drain outlet is fixedly connected to the inside of the bottom of the cleaning box, and the bottom end of the drain outlet passes through the cleaning box and extends to the outside of the bottom of the cleaning box.

[0009] As a preferred embodiment of this utility model, a sieve plate is movably connected inside the cleaning box, and a stop block is fixedly connected to the left side of both the top and bottom ends of the sieve plate.

[0010] As a preferred technical solution of this utility model, a movable block is movably connected to the bottom right side of the cleaning box. The two ends of the movable block extend to the front and back of the cleaning box and are movably connected to the front and back of the cleaning box, respectively. A first pneumatic cylinder located in front of the cleaning box is fixedly installed on the right side of the top of the base. The top of the first pneumatic cylinder is fixedly connected to the bottom of the movable block.

[0011] As a preferred embodiment of this utility model, a second pneumatic cylinder is fixedly installed on the left side of the back of the cleaning box, a movable block is fixedly connected to the front of the second pneumatic cylinder, and a first trapezoidal block is fixedly installed at the bottom of the movable block.

[0012] As a preferred embodiment of this utility model, the left end of the sieve plate is fixedly connected to an installation block, the left end of the installation block passes through the cleaning box and extends to the outside of the left end of the cleaning box, and the outer surface is movably connected to the inside of the cleaning box.

[0013] As a preferred embodiment of this utility model, a second trapezoidal block is fixedly connected to the top of the mounting block, the right side of the second trapezoidal block is movably connected to the left side of the cleaning box, and the front side of the second trapezoidal block is movably connected to the back side of the first trapezoidal block.

[0014] As a preferred embodiment of this utility model, a spring is fixedly connected to the right side of the bottom end of the mounting block, and the bottom end of the spring is fixedly connected to the inside of the cleaning box.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. In this disclosure, by setting up a motor, rotating shaft, rotating rod, long rod, and hollow tube, the operator first connects and fixes the cleaning fluid delivery hose to the hollow tube. Then, the cleaning fluid will pass through the hollow tube and hollow block and be sprayed from the nozzle into the cleaning tank. At this time, the operator starts the motor, which will cause the rotating shaft and rotating rod to rotate. This will cause the long rod to drive the moving block, hollow tube, hollow block, and nozzle to move back and forth. This allows the nozzle to spray the cleaning fluid evenly onto the outer surface of the fasteners at the top of the screen plate, eliminating the need for manual wiping and bringing convenience to the operator's work.

[0017] 2. In this disclosure, through the arrangement of the sieve plate, the second pneumatic cylinder, the first trapezoidal block, the second trapezoidal block, and the spring, the operator operates the second pneumatic cylinder, which causes the moving block to drive the first trapezoidal block to move backward. This causes the outer surface of the first trapezoidal block to press and push the outer surface of the second trapezoidal block, which in turn causes the second trapezoidal block to drive the mounting block and the entire sieve plate to move downward. At this time, the spring will be compressed. When the first trapezoidal block moves to the rear of the second trapezoidal block, due to the restoring effect of the spring force, the mounting block will drive the second trapezoidal block and the entire sieve plate to move upward. Then, the operator operates the second pneumatic cylinder again, which will cause the moving block to drive the first trapezoidal block back to its initial state. This repetition will produce a vibration effect on the entire sieve plate, thereby enabling the sieve plate to work with the nozzle to further improve the cleaning operation of the fasteners.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5As shown, a cold heading machine for continuous fastener production according to an embodiment of the present disclosure is illustrated. It includes a base 1, with support blocks 2 fixedly connected to the left and right sides of the top of the base 1. A cleaning box 3 is fixedly installed on the top of the support blocks 2. A motor 4 is fixedly installed on the top right side of the cleaning box 3. A rotating shaft 5 is fixedly sleeved on the other end of the output shaft of the motor 4. A rotating rod 6 is fixedly sleeved on the outer surface of the rotating shaft 5. A long rod 7 is hinged to the other end of the rotating rod 6. A moving block 8 is hinged to the other end of the long rod 7. The bottom end of the moving block 8 is movably connected to the top of the cleaning box 3. A hollow tube 9 is fixedly sleeved inside the moving block 8. The top end of the hollow tube 9 passes through the moving block 8 and extends to the outside of the top of the moving block 8. The bottom end of the hollow tube 9 passes through the moving block 8 and the cleaning box 3 in sequence and extends into the interior of the cleaning box 3 and is fixedly connected to a hollow block 10. A nozzle 11 is fixedly connected to the bottom end of the hollow block 10.

[0032] The operator connects and secures the cleaning fluid delivery hose to the hollow tube 9. Then, the operator starts the motor 4, which causes the rotating shaft 5 and the rotating rod 6 to rotate. This causes the long rod 7 to drive the moving block 8, the hollow tube 9, the hollow block 10, and the nozzle 11 to reciprocate left and right, thereby enabling the nozzle 11 to perform a uniform spray cleaning operation on the outer surface of the fasteners inside the cleaning box 3.

[0033] In some examples, a rectangular plate 12 located on the left side of the cleaning box 3 is fixedly connected to the top of the base 1 in both the front and rear directions, and the cold heading machine body 13 is fixedly installed on the top of the rectangular plate 12.

[0034] The design of the two rectangular plates 12 provides excellent support for the cold heading machine body 13.

[0035] In some examples, a connecting block 14 is fixedly connected to the top right side of the cold heading machine body 13. The right end of the connecting block 14 extends into the interior of the top left side of the cleaning box 3, and its outer surface is fixedly connected to the interior of the cleaning box 3.

[0036] Due to the design of the connecting block 14, the cold heading machine body 13 can drop the finished fasteners onto the top of the screen plate 16 via the connecting block 14.

[0037] In some examples, a drain outlet 15 is fixedly connected to the inside of the bottom of the cleaning box 3, and the bottom end of the drain outlet 15 passes through the cleaning box 3 and extends to the outside of the bottom of the cleaning box 3.

[0038] Due to the design of the drain outlet 15, wastewater inside the cleaning tank 3 can be discharged to the outside.

[0039] As a preferred technical solution of this utility model, a sieve plate 16 is movably connected inside the cleaning box 3, and a stop block 17 is fixedly connected to the left side of the top and bottom ends of the sieve plate 16.

[0040] When the sieve plate 16 moves, it will cause the two stops 17 to move together.

[0041] In some examples, a movable block 18 is movably connected to the bottom right side of the cleaning box 3. The two ends of the movable block 18 extend to the front and back of the cleaning box 3 respectively and are movably connected to the front and back of the cleaning box 3. A first pneumatic cylinder 19 located in front of the cleaning box 3 is fixedly installed on the right side of the top of the base 1. The top of the first pneumatic cylinder 19 is fixedly connected to the bottom of the movable block 18.

[0042] When the operator operates the first pneumatic cylinder 19, the movable block 18 will move upward.

[0043] In some examples, a second pneumatic cylinder 20 is fixedly installed on the left side of the back of the cleaning box 3, a movable block 21 is fixedly connected to the front of the second pneumatic cylinder 20, and a first trapezoidal block 22 is fixedly installed at the bottom of the movable block 21.

[0044] When the operator operates the second pneumatic cylinder 20, the moving block 21 will cause the first trapezoidal block 22 to move backward.

[0045] In some examples, a mounting block 23 is fixedly connected to the left end of the sieve plate 16. The left end of the mounting block 23 passes through the cleaning box 3 and extends to the outside of the left end of the cleaning box 3, and its outer surface is movably connected to the inside of the cleaning box 3.

[0046] The design includes mounting block 23, which effectively limits the movement of the sieve plate 16.

[0047] In some examples, the top of the mounting block 23 is fixedly connected to a second trapezoidal block 24, the right side of the second trapezoidal block 24 is movably connected to the left side of the cleaning box 3, and the front of the second trapezoidal block 24 is movably connected to the back of the first trapezoidal block 22.

[0048] When the second trapezoidal block 24 moves downward, it will cause the mounting block 23 and the sieve plate 16 to move downward together.

[0049] In some examples, a spring 25 is fixedly connected to the right side of the bottom end of the mounting block 23, and the bottom end of the spring 25 is fixedly connected to the inside of the cleaning box 3.

[0050] Due to the design of the spring 25, it can effectively reset the movement of the mounting block 23 and the screen plate 16 as a whole.

[0051] Working principle and usage process of this utility model:

[0052] First, after the fasteners are produced inside the cold heading machine body 13, they fall onto the top of the screen plate 16 via the connecting block 14. At this time, the cold heading oil on the outer surface of the fasteners will fall downwards through the screen plate 16. Then, the operator operates the second pneumatic cylinder 20, which causes the moving block 21 to drive the first trapezoidal block 22 to move backwards. This causes the outer surface of the first trapezoidal block 22 to press and push the outer surface of the second trapezoidal block 24, thereby causing the second trapezoidal block 24 to drive the mounting block 23 and the screen plate 16 to move downwards as a whole. When the first trapezoidal block 22 moves behind the second trapezoidal block 24, the restoring effect of the spring 25 will cause the mounting block 23 to drive the second trapezoidal block 24 and the screen plate 16 to move upward as a whole. When the operator controls the second pneumatic cylinder 20 to restore the moving block 21 and the first trapezoidal block 22 to their initial state, the second trapezoidal block 24 will move up and down again. This reciprocating motion will produce a vibration effect on the screen plate 16 as a whole, thereby accelerating the fall of cold heading oil from the outer surface of the fasteners on the top of the screen plate 16.

[0053] Finally, the operator connects and secures the cleaning fluid delivery hose to the hollow tube 9. The cleaning fluid will then be sprayed from the nozzle 11 into the cleaning tank 3 through the hollow tube 9 and the hollow block 10. At this time, the motor 4 is started, which will cause the rotating shaft 5 and the rotating rod 6 to rotate. This will cause the long rod 7 to drive the moving block 8, the hollow tube 9, the hollow block 10, and the nozzle 11 to reciprocate left and right. This will allow the nozzle 11 to evenly spray the cleaning fluid onto the outer surface of the fastener at the top of the sieve plate 16, thus performing a vibration-based cleaning operation. After cleaning is completed, the operator can operate the first pneumatic cylinder 19, causing the movable block 18 to move upward, thereby discharging the fastener at the top of the sieve plate 16 outward.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
