Abstract

This invention discloses a rotary adjustable crystal marker, including a storage box. Slide rods are installed at the bottom of both sides inside the storage box. Foam boards are slidably installed on the outer sides of the two sets of slide rods. A scale plate is installed at the center of the top of the storage box. A winding shaft is rotatably installed at the center of the bottom of one end of the front of the scale plate. A coil spring is installed at the back end of the outer side of the winding shaft. This invention features a rotatable disc with four marking mechanisms inside. Rotating the disc causes the first connecting sleeve and the drive slider to rotate as a whole, allowing the drive slider to slide inside the coil spring. When it moves to the vertical slot, it slides inward under gravity, causing the corresponding marking head to move out from the storage slot. This allows for quick selection of the required marking head, reducing the hassle of changing equipment and the need for equipment purchases. Changing different marking heads is not only simple and convenient, but also involves fewer and faster operation steps.

Description

Technical Field

[0001] This invention relates to the field of crystal marker technology, specifically to a rotary adjustable crystal marker. Background Technology

[0002] With social progress and the rapid development of the machinery manufacturing industry, my country's development and utilization of crystals are becoming increasingly advanced. For example, the production of some crystal glass and the exquisite production of some jewelry crystals demonstrate my country's advanced level in crystal processing. Before crystal processing, the dimensions need to be marked by a crystal marker. Only after marking can processing begin.

[0003] Current crystal markers have certain shortcomings in use:

[0004] First, crystal markers typically have only one marking head, so they can only generate one type of mark when marking crystals. However, when marking crystals of different sizes and specifications, different batches, or the same crystals that need to be marked with different shapes at different locations, crystal markers with different marking heads are required. This not only increases the cost of purchasing equipment but also makes it difficult to mark quickly.

[0005] Meanwhile, when crystal markers are used for a long time under high intensity, the marking head is easily damaged. Damaged marking heads will result in unclear markings and irregular shapes. This will cause certain deviations during subsequent processing, increase the defect rate, and cause certain economic losses.

[0006] Furthermore, when using the marker, it is necessary to constantly monitor whether the coating inside has been used up and to add it in a timely manner. Failure to add it in time will delay the crystal production process and affect the subsequent production progress. However, it is usually observed manually through the addition hole, but this method of observation has a large margin of error. Summary of the Invention

[0018] Compared with the prior art, the present invention provides a rotary adjustable crystal marker, which has the following advantages:

[0019] 1. This invention features a rotatable disc with four marking mechanisms inside. When marking different batches and sizes of crystals, the marking heads can be easily replaced. Rotating the disc causes the first connecting sleeve and the drive slider to rotate as a whole, allowing the drive slider to slide inside the coil spring. When it reaches the vertical slot, it slides inward under gravity, causing the corresponding marking head to move out of the storage slot. This allows for quick selection of the required marking head, reducing the hassle of changing equipment and the need for new equipment. Changing different marking heads is not only simple and convenient, but also involves fewer and faster operation steps.

[0020] 2. This invention utilizes a detachable design between the first and second connecting sleeves, allowing the marking head to be quickly and easily removed from the first connecting sleeve. When the marking head becomes damaged after a period of use, the two sets of pressing rods can be pushed into the first connecting sleeve, causing the second fixing rod to move out of the second fixing groove, thus releasing the fixing effect on the second connecting sleeve. At this point, the second connecting sleeve can be pulled out from the inside of the first connecting sleeve, completing the removal of the marking head and allowing a new marking head to be installed. This not only solves the problem of unclear markings caused by damaged marking heads but also avoids the impact on processing accuracy and quality caused by unclear markings, reducing the defect rate and improving the production qualification rate.

[0021] 3. This invention, through the interaction between the pointer and the scale plate, allows for the most intuitive understanding of the amount of residual pigment inside the storage bin. As the pigment gradually decreases, the foam board gradually descends, pulling the pull rope downwards. The pull rope drives the winding shaft to rotate on the scale plate, which in turn drives the pointer to rotate, causing the pointer to point to the scale line number on the scale plate. The amount of pigment inside the storage bin can be read directly without observing through the filling port, and observing the scale plate is more convenient and simple. Attached Figure Description

The first connecting sleeve 301 is located at one end of the telescopic hose 203. Limiting sliders 302 are provided on the top of both sides of the first connecting sleeve 301, and driving sliders 303 are provided on the top of both ends of the first connecting sleeve 301. The inner side of the first connecting sleeve 301... A connecting ring 306 is provided at the bottom, and a movable cavity 307 is provided at the inner edge of the connecting ring 306. A pressing rod 310 is sleeved inside the two sets of movable cavities 307. A return spring 308 is provided on the side of the two sets of pressing rods 310 that are close to each other. A second fixing rod 309 is provided at the bottom of the two sets of pressing rods 310. A second connecting sleeve 305 is sleeved at the bottom inside the first connecting sleeve 301. A second fixing groove 311 is provided at the top of both sides inside the second connecting sleeve 305. A marking head 304 is provided at the bottom of the second connecting sleeve 305, which can be quickly replaced.

[0036] As a preferred embodiment, an annular sealing groove is provided at the bottom edge of the connecting ring 306, and the second connecting sleeve 305 is adapted to the annular sealing groove to reduce pigment leakage.

[0037] As a preferred embodiment, one side of the second fixing rod 309 extends out of the interior of the movable cavity 307, and the second fixing rod 309 and the second fixing groove 311 are mutually adapted.

[0038] As a preferred embodiment, a fixing ring is provided on the top of the foam board 10, and the other end of the pull rope 7 passes through the inside of the through hole 8 and is tied to the fixing ring, so that the pull rope 7 is more securely fixed to the foam board 10.

[0039] As a preferred embodiment, one side of the limiting slider 302 extends to the limiting groove 206 and slides against each other, and one end of the two sets of driving sliders 303 extends into the interior of the annular groove 21 and slides.

[0040] As a preferred embodiment, the top of the sphere 207 is provided with a handle, and one side of the handle extends out of the interior of the rotating disk 201, which facilitates the rotation of the sphere 207.

[0041] As a preferred embodiment, one side of the rotary joint 16 extends into the interior of the flow guide cavity 204, and one side of the connecting pipe 205 extends into the interior of the flow guide cavity 204, so that the pigment can smoothly enter the interior of the marking head 304.

[0042] As a preferred embodiment, one end of the coil spring 18 is fixedly connected to the scale plate 4, and the top and bottom of the compression spring 14 are fixedly connected to the connecting plate 13 and the U-shaped plate 9 respectively, so that the coil spring 18 will not rotate with the winding shaft 6.

[0043] Example 1, such as Figure 3-5 As shown, when replacing the marker head 304, the two sets of first fixing rods 15 are pulled out from the inside of the first fixing groove 210. The rotating disk 201 can then be rotated, causing the four sets of first connecting sleeves 301 to rotate. The bottommost first connecting sleeve 301 will cause the drive slider 303 located inside the vertical groove 20 to move. The drive slider 303 will move into the inclined groove 17. After rotating ninety degrees, the drive slider 303 moves back into the annular groove 21 through the inclined groove 17. When the drive slider 303 moves inside the inclined groove 17, it simultaneously drives the first connecting sleeve 301 to move into the storage groove 202 for storage. The adjacent first connecting sleeve 301 drives the drive slider 303 to move to the vertical groove 20. The first connecting sleeve 301 will move into the vertical groove 20 under the action of gravity. Move the first connecting sleeve 301 and the marking head 304 into the storage groove 202 to complete the adjustment and replacement. Then, insert the first fixing rod 15 into the first fixing groove 210 to fix the rotating disk 201.

[0044] Example 2, as Figure 4-6 As shown, when marking, the flow rate of the connecting pipe 205 can be adjusted according to the actual situation. At this time, rotating the corresponding handle will drive the ball 207 to rotate, and the ball 207 will drive the channel 209 to rotate at a certain angle, so that the channel 209 is rotated into the interior of the mounting sleeve 208. The larger the channel 209 is exposed to the outside, the greater the flow rate, and vice versa.

[0045] Working principle: First, the material to be used is added to the inside of the storage box 1. At this time, the foam board 10 will move upward along the slide bar 11 due to the buoyancy. At this time, the pull rope 7 will slack due to the lack of tension. At this time, the coil spring 18 will drive the winding shaft 6 to rotate, which can wind and wind the pull rope 7. The pointer 5 will also move back to its original position.

[0046] In use, the ball 207 corresponding to the mark head 304 is rotated by the handle, so that a passage is formed inside the connecting pipe 205. At this time, the pigment inside the storage tank 1 enters the interior of the guide cavity 204 through the two sets of guide tubes 12, and then flows into the interior of the connecting pipe 205 through the guide cavity 204. It then enters the interior of the mark head 304 through the telescopic hose 203, the first connecting sleeve 301 and the extrusion rod 310 in sequence. The mark head 304 can mark the crystal by driving the drive mechanism.

[0047] When the marking head 304 needs to be replaced, the two sets of compression rods 310 can be pushed into the first connecting sleeve 301, causing the second fixing rod 309 to move out of the second fixing groove 311, releasing the fixing effect on the second connecting sleeve 305. At this time, the second connecting sleeve 305 can be pulled out from the inside of the first connecting sleeve 301, completing the disassembly of the marking head 304. The new marking head 304 can then be installed. The first connecting sleeve 301 is not inserted into the first connecting sleeve 301, but pushed into the annular sealing groove at the bottom of the connecting ring 306. At this time, the two sets of compression rods are released. 310. Under the action of two sets of return springs 308, the extrusion rod 310 contacts the inner side of the second fixing rod 309. At this time, the second connecting sleeve 305 is rotated. When the second connecting sleeve 305 moves the second fixing groove 311 to the position of the second fixing rod 309, it is springed into the interior of the second fixing groove 311 by the return spring 308, thus fixing the second connecting sleeve 305. This not only solves and reduces the problem of unclear marking caused by damage to the marking head 304, but also avoids the impact on processing accuracy and quality caused by unclear marking, reducing the defect rate and improving the production qualification rate.

[0048] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
