Description

Technical Field

[0001] This utility model relates to the field of pneumatic engraving machines, and in particular to a slide rail structure suitable for pneumatic engraving machines. Background Technology

[0002] Pneumatic engraving machines use air pressure to drive a slider, which in turn moves the engraving head to carve text and patterns. They are widely used in industries such as machinery manufacturing, hardware processing, and signage. The slide rail structure is the core transmission component of a pneumatic engraving machine, and its performance directly determines the engraving accuracy (clarity of characters, dimensional error), equipment lifespan, and production efficiency. The slide rail structure in the engraving head lifting mechanism is fundamental to ensuring stable engraving.

[0003] A search of Chinese patents revealed publication number CN217731698U, which describes a double-slide rail structure. This structure comprises a base, a first sliding mechanism, a connecting seat, a second sliding mechanism, an equipment mounting base, a drive motor, a driving wheel, a driven wheel, a synchronous belt, a first clamping assembly, and a second clamping assembly. The equipment mounting base is used to mount equipment. When the drive motor drives the driving wheel to rotate, the connecting seat and the equipment mounting base slide synchronously in the same direction. Compared to the traditional single-slide rail structure, for the same travel distance, this double-slide rail structure offers higher movement efficiency, reduces space occupation, and has a shorter synchronous belt length.

[0004] Existing slide rail structures lack protective functions, and are generally exposed. Metal shavings and dust generated during the engraving process can easily enter the gap between the slide rail and the slide base. The accumulation of impurities causes the slider to jam, increases the resistance to movement, accelerates wear, reduces service life, and affects the stability of engraving. In order to solve the above problems, we propose a slide rail structure suitable for pneumatic engraving machines. Utility Model Content

[0005] The purpose of this invention is to provide a slide rail structure suitable for pneumatic engraving machines, which has the advantage of providing a protective function.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a slide rail structure suitable for a pneumatic engraving machine, including a fixed base, a sliding mechanism provided on the surface of the fixed base, two fixed shells bolted to the top of the fixed base, a rotating shaft rotatably sleeved on the inner wall of the fixed shell, a take-up drum rotatably sleeved on the surface of the rotating shaft, a coil spring provided between the inner wall of the take-up drum and the surface of the rotating shaft, a dustproof cloth installed on the surface of the take-up drum, a slide rod bolted to one end of the dustproof cloth, a transmission rod slidably connected to the inner wall of the slide rod, a snap-fit ​​connector bolted to the surface of the transmission rod, a snap-fit ​​hole snapped into one end of the snap-fit ​​connector, a first spring provided between one end of the transmission rod and the inner wall of the slide rod, a toggle block bolted to the surface of the transmission rod, and a protective plate bolted to the surface of the fixed base.

[0007] By adopting the above technical solution, a dustproof cloth is installed. When the slide moves, the dustproof cloth moves with the slide under the action of the second coil spring, thus protecting the slide rail. This achieves the purpose of protection, ensures the stability of the slide rail and the effect of engraving, and improves the service life of the slide rail. By moving the toggle block to disengage the locking joint from the locking hole, the dustproof cloth can be opened, which facilitates the maintenance of the slide rail, improves practicality, and makes it convenient to use.

[0008] The present invention is further configured such that: a fixing block is bolted to the surface of the fixing shell, and the fixing block is rotatably sleeved with the surface of the rotating shaft; a ratchet is fixedly sleeved on the surface of the rotating shaft; a sliding block is slidably connected to the inner wall of the fixing block; a telescopic block is slidably sleeved on the inner wall of the sliding block; a second spring is provided between the telescopic block and the inner wall of the sliding block; a ratchet block is bolted to the surface of the telescopic block, and the ratchet block meshes with the ratchet; an adjusting bolt is rotatably connected to the surface of the sliding block, and the adjusting bolt is threadedly connected to the inner wall of the fixing block.

[0009] By adopting the above technical solution, the rotating head is rotated to make the rotating shaft rotate. The rotation of the rotating shaft tightens the coil spring, thereby adjusting the preload of the coil spring and ensuring the tension and performance of the dustproof cloth. The ratchet block engages with the ratchet wheel under the action of the second spring to prevent the rotating shaft from rotating in the opposite direction, ensuring the stability of use and facilitating adjustment.

[0010] The present invention is further configured such that: the sliding mechanism includes two slide rails, the slide rails are bolted to the surface of the fixed seat, a slide block is slidably connected to the surface of the slide rails, and a snap-fit ​​hole is opened on the surface of the slide block; a screw is threadedly connected to the inner wall of the slide block, and the screw is rotatably sleeved with the inner wall of the fixed seat; a motor is bolted to one end of the screw, and the motor is bolted to the surface of the fixed seat.

[0011] By adopting the above technical solution, a slider mechanism is set up. The rotation of the motor drives the screw to rotate, and the rotation of the screw drives the slide block to move along the slide rail, which is convenient to use.

[0012] The present invention is further configured such that: a support rod is bolted to the bottom of the dustproof cloth, and rollers are rotatably connected to both ends of the support rod; a guide groove is provided on the surface of the protective plate, and the inner wall of the guide groove is adapted to the rollers.

[0013] By adopting the above technical solution, support rods, rollers and guide grooves are set to support the dustproof cloth, prevent the dustproof cloth from collapsing and affecting its use, and improve its stability.

[0014] The present invention is further configured such that a nut is threaded onto the surface of the adjusting bolt.

[0015] By using the above technical solution, the adjusting bolt is fixed by setting a nut to prevent loosening.

[0016] The present invention is further configured such that an adjusting head is bolted to one end of the rotating shaft.

[0018] The present invention is further configured such that one end of the card connector is wedge-shaped.

[0019] By adopting the above technical solution, one end of the snap-fit ​​connector is wedge-shaped, which facilitates the fixing of the slide rod and makes installation convenient.

[0020] The present invention is further configured such that: the inner wall of the winding drum is bolted with a partition, and the partition is rotatably sleeved with the surface of the rotating shaft.

[0021] By adopting the above technical solution, a partition is set to prevent the coil spring from deforming and ensure the stability of the coil spring.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model, by setting a dustproof cloth, protects the slide rail by moving the dustproof cloth with the slide rail under the action of the second coil spring when the slide rail moves. This achieves the purpose of protection, ensures the stability of the slide rail and the effect of engraving, and improves the service life of the slide rail. By moving the toggle block to disengage the locking joint from the locking hole, the dustproof cloth can be opened, which facilitates the maintenance of the slide rail, improves practicality, and makes it convenient to use. 2. This utility model rotates the adjusting head to make the rotating shaft rotate. The rotation of the rotating shaft tightens the coil spring, thereby adjusting the preload of the coil spring and ensuring the tension and performance of the dustproof cloth.

[0034] Brief description of operation: Motor 25 drives screw 24 to move slide 23. The movement of slide 23 moves dustproof cloth 7. When slide 23 moves to one end, the winding drum 5 at that end will wind up dustproof cloth 7 under the action of coil spring 6, causing dustproof cloth 7 to enter the fixed housing 3 and tighten. Dustproof cloth 7 at the other end will move with slide 23, causing winding drum 5 to drive coil spring 6 to tighten, so that dustproof cloth 7 can retract when slide 23 moves. This works in conjunction with protective plate 14 to protect slide rail 22, thus achieving the purpose of protection. When maintaining slide rail 22, move toggle block 13. The movement of toggle block 13 drives transmission rod 9 to move, and the movement of transmission rod 9 drives snap-fit ​​connector 10 to... When the snap-fit ​​hole 11 is disengaged, the dust cover 7 is opened for maintenance. After maintenance, the snap-fit ​​connector 10 is snapped into the snap-fit ​​hole 11. Under the action of the first spring 12, the snap-fit ​​connector 10 ensures the stability of the snap-fit, thus facilitating maintenance. When it is necessary to tighten the coil spring 6, rotate the adjusting head 30. The rotation of the adjusting head 30 drives the rotating shaft 4 to rotate, which in turn causes the coil spring 6 to tighten. When loosening, loosen the nut 29 and rotate the adjusting bolt 21 to disengage the ratchet block 20 from the ratchet wheel 16. Then, adjust the adjusting head 30 to adjust the coil spring 6 to the required preload. Then, rotate the adjusting bolt 21 in the opposite direction to engage the ratchet block 20 with the ratchet wheel 16 and fix it, thereby achieving the purpose of adjusting the preload of the coil spring 6.
