Detailed Description

Preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the embodiment of the present utility model provides a sliding track of a capsule machine, which comprises a track frame 100, wherein at least one side of the track frame 100 is provided with a slide support 200 extending along the length direction of the track frame 100 (for example, the slide support 200 can be fixed on the track frame 100 through screws), the slide support 200 is provided with at least one mounting groove 210, a shaft 220 is arranged in the mounting groove 210, and a needle bearing 230 is sleeved outside the shaft 220; two slide pressing plates 300 (for example, fixedly connected with the slide support 200 through screws) are arranged on one side of the slide support 200 away from the track frame 100, and a sliding groove 310 extending along the length direction of the track frame 100 is formed between the two slide pressing plates 300; as shown in fig. 4, the needle module 400 includes a long strip plate 410 and a plurality of needle modules 420 fixed on the long strip plate 410, the long strip plate 410 is positioned in the chute 310 when sliding on the sliding rail, and the needle modules 420 extend out of the chute 310; the installation groove 210 is communicated with the sliding groove 310, and the needle bearing 230 partially extends into the sliding groove 310 to be abutted against one side of the long slat 410, and the other side of the long slat 410 is abutted against the side walls of the two sliding-way pressing plates 300, so that the long slat 410 is prevented from tilting. In the sliding process, the long slat 410 is located in the sliding groove 310 and between the needle bearing 230 and the slideway pressing plate 300, so that the long slat 410 contacts with the needle bearing 230 and/or the slideway pressing plate 300 and rubs against each other, because the needle bearing 230 can rotate around the shaft 220, when the long slat 410 slides relative to the needle bearing 230 under the action of external force, the needle bearing 230 can rotate around the shaft 220 under the action of friction force between the two, and therefore, the friction between the needle bearing 230 and the shaft 220 is the friction between the needle bearing 230 and the long slat 410, and the friction between the needle bearing 230 and the long slat 410 is also the friction between the needle bearing and the long slat 410, compared with the friction between the long slat 410 and the other protrusions, the friction force is greatly reduced, so that the resistance of the long slat 410 in the sliding process is reduced.

In the embodiment shown in fig. 1, the rail frame 100 is provided with a slide rail bracket 200 on both sides so that two needle modules 400 can slide on the slide rail.

As shown in fig. 3, in some embodiments, at least one elastic member 500 is provided at a position of the track frame 100 corresponding to the mounting groove 210, for providing an elastic force to the shaft 220 to move the shaft 220 away from the track frame 100, so that the needle bearing 230 presses the long slat 410, so that the long slat 410 does not topple over when sliding in the sliding slot 310, and the elastic member 500 can be extended and contracted in response to the movement of the long slat 410, so that the sliding of the long slat 410 is smoother.

The elastic member 500 may be a compression spring, a spring plate, rubber, or any other suitable elastic element. The number of elastic members 500 may be set as desired.

In one exemplary embodiment, the elastic members 500 are provided in two, and elastic forces are applied to both ends of the shaft 220, respectively, so that the shaft 220 is far away from the track frame 100 and the needle bearings 230 are pressed against the long strip plate 410.

In some embodiments, the rail frame 100 is provided with a receiving groove 110, one end of the elastic member 500 is positioned in the receiving groove 110 and connected to the rail frame 100, and the other end of the elastic member 500 is extended into the mounting groove 210 and connected to the shaft 220, thereby providing an elastic force to the shaft 220. That is, the receiving groove 110 communicates with the mounting groove 210 (e.g., through holes in the slide bracket 200), the elastic member 500 passes through the through holes in the slide bracket 200, and both ends are respectively located in the receiving groove 110 and the mounting groove 210. Specifically, the elastic member 500 may be in a compressed state, and both ends thereof are respectively abutted against the track frame 100 and the shaft 220 (i.e., compressed between the track frame 100 and the shaft 220), and the elastic member 500 is limited by the receiving groove 110.

As shown in fig. 3, in some embodiments, at least one adjusting screw 320 is provided on the slideway platen 300, and one end of the adjusting screw 320 is inserted into the mounting groove 210 and is detachably contacted with the shaft 220, so as to provide a force opposite to the elastic force to the shaft 220. By tightening or loosening the adjustment screw 320, the position of the shaft 220 can be adjusted, thereby adjusting the magnitude of the elastic force, i.e., the tightness of the elastic member 500. For example, when the adjusting screw 320 is tightened, the shaft 220 will move in a direction approaching the track frame 100, thereby increasing the compression amount of the elastic member 500, so that the elastic force becomes large; conversely, when the adjusting screw 320 is unscrewed, the shaft 220 will move in a direction away from the track frame 100, and the compression amount of the elastic member 500 becomes smaller, so that the elastic force becomes smaller.

In the embodiment shown in fig. 3, two adjusting screws 320 are provided and are in contact with the two ends of the shaft 220, respectively. It will be appreciated that the number and position of the set screws 320 may also be adjusted as desired, provided that positional adjustment of the shaft 220 is enabled.

The number of the installation grooves 210 on the chute support 200 may be set as required, for example, one or more, and when the installation grooves 210 are plural, the installation grooves 210 may be uniformly arranged along the extending direction of the chute support 200.

In an exemplary embodiment, three mounting grooves 210 are provided on each of the slide holders 200, one of the mounting grooves 210 is located at the middle of the slide holder 200, one shaft 220 is provided in each of the mounting grooves 210, and elastic members 500 and adjusting screws 320 are provided at the corresponding positions of the rail holder 100 and the slide pressing plate 300 to each of the mounting grooves 210, so that when the needle module 400 slides on the sliding rail, the long strip 410 has three positions closely contacted with the needle bearings 230 on the shaft 220, thereby making the resistance of the long strip 410 smaller and the sliding smoother.

In some embodiments, the long strip plate 410 may be provided with a plurality of receiving holes, and one end (fixed end) of the pin mold 420 is formed in a shape matching the receiving holes, such that the pin mold 420 is fixed to the long strip plate 410 by inserting the fixed end of the pin mold 420 into the receiving holes.

According to the sliding track of the capsule machine, the needle bearing 230 is sleeved on the outer side of the shaft 220, so that the needle bearing 230 is abutted against the long strip plate 410 of the needle module 400, and friction between the long strip plate 410 and the needle bearing 230 and between the needle bearing 230 and the shaft 220 is linear and planar, so that the resistance of the long strip plate 410 in sliding is reduced; while also reducing wear of the slat 410 during sliding.

The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the scope of the present utility model, and various modifications can be made to the above-described embodiment of the present utility model. All simple, equivalent changes and modifications made in accordance with the claims and the specification of this application fall within the scope of the patent claims. The present utility model is not described in detail in the conventional art.
