Technical Field
[0001] This utility model belongs to the field of marking machine technology, specifically a manual opening structure for a marking machine with automatic springback. Background Technology
[0002] The discharge valve handle of a line marking machine is a key component used to control the opening and closing of the discharge valve, thereby regulating the flow of paint. The discharge valve handle is an operating device that allows the operator to control the opening and closing of the discharge valve manually or electrically. When the discharge valve is open, paint flows from the cartridge and is applied to the ground via the marking wheel or other means. When it is necessary to stop marking or adjust the paint flow, the discharge valve can be closed by operating the handle. In manual operation, the handle is connected to the discharge valve via a linkage mechanism; when the handle is turned, it drives the mechanism to open or close the discharge valve. Existing line marking machine discharge valve handles lack automatic spring-back capability, making valve opening inconvenient and affecting operator use. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a manual opening structure for a marking machine with automatic springback, which effectively solves the problem that the opening and closing handle of the feed valve of the existing marking machine does not have automatic springback capability, making it very inconvenient to open the valve and affecting the operation of the operator.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a manual opening structure for a marking machine with automatic rebound, comprising a support platform, with rollers rotatably mounted at the four corners of the bottom of the support platform, a material cylinder fixedly mounted on one side of the top of the support platform, and an equipment box fixedly mounted on the other side of the top of the support platform. A guide pin is hinged to one end of the upper part of the support platform, a discharge valve is movably mounted on the lower part of the surface of the material cylinder, a moving rod is rotatably mounted on the front of the discharge valve, a transmission rod is rotatably mounted on the top of the moving rod, a handle is fixedly mounted on the top of the transmission rod, a positioning strip is rotatably mounted on the middle of the transmission rod, the lower end of the positioning strip is fixedly connected to one side of the equipment box, a fixing block is fixedly mounted on the upper part of one side of the equipment box, an arc-shaped insert rod is fixedly mounted on the top of the fixing block, the arc-shaped insert rod is movably inserted into the upper part of the transmission rod, a telescopic spring is sleeved on the surface of the arc-shaped insert rod, the two ends of the telescopic spring are fixedly connected to the arc-shaped insert rod and the transmission rod respectively, and the upper end of the transmission rod... The device is equipped with an arc-shaped insertion tube. The top of the arc-shaped insertion tube is fixedly connected to one side of the equipment box via a fixing strip. The bottom of the arc-shaped insertion tube is equipped with a pull ring. Limiting rods are movably inserted into both sides of the upper end of the arc-shaped insertion tube. Contact heads are fixedly installed at the ends of the two limiting rods that are far apart from each other, and connecting strips are fixedly installed at the ends of the two limiting rods that are close to each other. Sliding sleeves are fixedly installed at both ends of the two connecting strips. Two sliding rods are inserted between the four sliding sleeves. The two ends of the two sliding rods are fixedly connected to the inner walls of both sides of the arc-shaped insertion tube. Return springs are sleeved on the surface of the two sliding rods. The two ends of the two return springs are fixedly connected to the four sliding sleeves. A transmission component is provided on the circumference of the pull ring. The transmission component is connected to the two sliding sleeves. When the pull ring is pulled, the power is output to two of the sliding sleeves through the transmission component. This causes the two sliding sleeves to drive the two limiting rods and the two contact heads to retract into the arc-shaped insertion tube and release the limiting position through the two connecting strips.
[0005] Preferably, the transmission assembly includes a pull rod, which is fixedly installed on the upper part of the circumferential surface of the pull ring, and one end of the pull ring extends into the interior of the arc-shaped insertion tube and is fixedly installed with a connecting plate.
[0006] Preferably, a lower limiting sleeve is fitted at the lower end of the pull rod surface, and the lower limiting sleeve is fixedly installed at the bottom of the arc-shaped insertion tube. An upper limiting sleeve is fitted at the upper end of the pull rod surface, and the surface of the upper limiting sleeve is fixedly connected to the inner walls of both sides of the arc-shaped insertion tube by two fixing rods.
[0007] Preferably, push-pull rods are rotatably installed at both ends of one side of the connecting plate, and one end of each push-pull rod is rotatably connected to one of the two sliding sleeves.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator pulls the pull rod down by pulling the ring. The pull rod moves along the inside of the upper limit sleeve and the lower limit sleeve, which increases the stability of the pull rod when it moves. When the pull rod moves down, it will drive the two push-pull rods down through the connecting plate. When the two push-pull rods move down, they will pull two of the sliding sleeves to move towards each other. When the two sliding sleeves move towards each other, they will drive the other two sliding sleeves to move towards each other through the two connecting bars. When the four sliding sleeves move, they will slide along the surface of the two sliding rods and simultaneously squeeze the two return springs, thereby ensuring the stability of the four sliding sleeves while giving them an elastic return effect. When the two connecting bars move towards each other, they will drive the two limit rods and the two contact heads to move towards each other and retract into the inside of the arc-shaped insertion tube to release the limit on the transmission rod.
[0009] After the limit on the transmission rod is released, the elastic force of the telescopic spring will drive one end of the transmission rod to rotate downward along the positioning strip. When one end of the transmission rod rotates downward, it will drive the other end to rotate upward, which will lift the discharge valve upward through the moving rod and open it, thus allowing the ink in the barrel to flow out. This gives the discharge valve handle of the marking machine an automatic springback capability, making it very convenient to open the valve and easy for operators to use. Attached Figure Description

A material cylinder 3 is fixedly mounted on one side of the top of the support platform 1, and an equipment box 10 is fixedly mounted on the other side of the top of the support platform 1. A guide pin 4 is hinged to one end of the upper part of the support platform 1. A discharge valve 5 is movably mounted on the lower part of the surface of the material cylinder 3. A moving rod 7 is rotatably mounted on the front of the discharge valve 5. A transmission rod 8 is rotatably mounted on the top of the moving rod 7. A handle 11 is fixedly mounted on the top of the transmission rod 8. The middle part of the transmission rod 8 rotates... A positioning strip 9 is movably installed, with its lower end fixedly connected to one side of the equipment box 10. A fixing block 12 is fixedly installed on the upper part of one side of the equipment box 10, and an arc-shaped insert rod 13 is fixedly installed on the top of the fixing block 12. The arc-shaped insert rod 13 is movably inserted into the upper part of the transmission rod 8. A telescopic spring 14 is sleeved on the surface of the arc-shaped insert rod 13, and both ends of the telescopic spring 14 are fixedly connected to the arc-shaped insert rod 13 and the transmission rod 8, respectively. An arc-shaped insert tube 15 is movably inserted into the upper end of the transmission rod 8, and the top of the arc-shaped insert tube 15 is open to... The curved insertion tube 15 is fixedly connected to one side of the equipment box 10 via a fixing strip. A pull ring 16 is provided at the bottom of the curved insertion tube 15. Limiting rods 17 are movably inserted into both sides of the upper end of the curved insertion tube 15. Contact heads 18 are fixedly installed at the ends of the two limiting rods 17 that are far apart from each other, and connecting strips 6 are fixedly installed at the ends of the two limiting rods 17 that are close to each other.

Both ends of the two sliding rods 27 are respectively connected to the curved insertion tube 15. The inner walls on both sides are fixedly connected. The surfaces of the two slide rods 27 are each fitted with a return spring 26. The two ends of the two return springs 26 are respectively fixedly connected to the four slide sleeves 25. The circumferential surface of the pull ring 16 is provided with a transmission component. The transmission component is connected to the two slide sleeves 25. When the pull ring 16 is pulled, the power is output to two of the slide sleeves 25 through the transmission component, so that the two slide sleeves 25 drive the two limit rods 17 and the two contact heads 18 to retract into the interior of the arc-shaped insertion tube 15 to release the limit through the two connecting bars 6.
[0019] In use, the operator pulls the transmission assembly through the pull ring 16. When the transmission assembly is running, it pulls two of the sliding sleeves 25 to move towards each other.

An upper limit sleeve 21 is fitted on the upper end of the surface of the pull rod 19, and the surface of the upper limit sleeve 21 is fixedly connected to the inner walls of both sides of the arc-shaped insertion tube 15 through two fixing rods 22. Push-pull rods 24 are rotatably installed on both ends of one side of the connecting plate 23, and one end of the two push-pull rods 24 is rotatably connected to two of the sliding sleeves 25.
[0022] In use, the operator pulls the lever 19 downwards via the pull ring 16. The lever 19 slides along the inside of the upper limit sleeve 21 and the lower limit sleeve 20, increasing the stability of the lever 19 during movement. When the lever 19 moves downwards, it drives the two push-pull rods 24 downwards via the connecting plate 23. When the two push-pull rods 24 move downwards, they pull two of the sliding sleeves 25 to move towards each other. When the two sliding sleeves 25 move towards each other, they drive the other two sliding sleeves 25 to move towards each other via the two connecting bars 6.
