Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The following description is made in detail with reference to the specific embodiments, and fig. 1, fig. 2, and fig. 3 respectively show the schematic perspective view of the hopper dragging mechanism for the tool cabinet, and the partial enlarged views of fig. I and II, which are mainly composed of several parts, such as a connecting part 1, a synchronous belt 2, a driving synchronous wheel 3, a driven synchronous wheel 4, a transmission shaft 5, and a driving part 6, wherein the connecting part 1 is used to realize the connection between the hopper and the synchronous belt 2 and the transmission of the dragging force, and the number thereof is set to 2 sets, and the connecting part is symmetrically distributed on the left and right sides of the hopper. The quantity of initiative synchronizing wheel 3 and driven synchronizing wheel 4 also all sets up to 2 sets, and supporting use in groups, and driven synchronizing wheel 4 is fixed in directly over initiative synchronizing wheel 3 for support hold-in range 2. The driving synchronizing wheel 3 is fixed on the left and right sides of the transmission shaft 5 in a key connection manner. The driving part 6 is provided as a set, is disposed at one end of the transmission shaft 5, and drives the driving synchronizing wheel 3 to perform a synchronous rotational motion, and at the same time, the hopper performs a reciprocating motion in an up-and-down direction by means of a drag force of the synchronous belt 2 (as shown in fig. 5). Therefore, the synchronous transmission without slip is realized, the accurate transmission ratio is obtained, and the advantages of stable transmission, buffering and vibration reduction are also realized. In addition, more importantly, the hopper is dragged in a bilateral synchronous driving mode, so that the left side and the right side of the hopper are stressed uniformly, the abrasion rate of the sliding block set of the sliding rail matched with the hopper is reduced, and the later maintenance frequency and cost are further reduced.

It is important to note here that the coupling of the driving synchronizing wheel 3 and the propeller shaft 4 is preferably splined. Because the spline connection mode needs to uniformly manufacture more teeth and grooves at the combination part of the driving synchronous wheel and the transmission shaft, the stress of the spline connection is uniform; the stress concentration at the tooth root is small due to the shallow groove, so that the service life is long; furthermore, the number of simultaneously released teeth is large, and the total contact area is large, so that a large load can be borne.

In view of improving the installation convenience of the driven synchronizing wheel 4, as a further optimization of the hopper dragging mechanism, a supporting frame 7 is additionally arranged and is provided with an installation groove 71 (shown in fig. 3). The driven synchronizing wheel 4 is rotatably fixed in the mounting groove 71 by means of a hinge shaft, and hinge shaft mounting holes (not shown) for the hinge shaft to pass through are correspondingly formed on both side walls of the mounting groove 71.

As a further refinement of the structure of the above-described connection portion 1, the following configuration may be referred to: the connecting portion 1 is mainly composed of an L-shaped fixing plate 11 and an abutting plate 12, wherein the timing belt 2 is sandwiched between the L-shaped fixing plate 11 and the abutting plate 12 (as shown in fig. 4). On the inner side of the abutting plate 12, there is provided a disengagement preventing tooth 121 (shown in fig. 6) in conformity with the tooth form of the timing belt 2. Therefore, the purpose of rapidly dismounting and mounting the synchronous belt 2 can be effectively achieved, the synchronous belt 2 can be effectively prevented from sliding relative to the connecting part 1, the stability of the hopper is improved, and the inclined phenomenon in the lifting process is prevented.

Further, the L-shaped fixing plate 11 and the abutting plate 12 can be detachably connected by means of bolts, and accordingly, elongated waist-shaped holes 111 adapted to the bolts are formed in the L-shaped fixing plate 11 and extend in the left-right direction (as shown in fig. 4). Therefore, in the process of installing the synchronous belt 2, the synchronous belt can be conveniently adjusted along the left and right directions according to specific practical conditions, and the synchronous belt is ensured to be in the same straight line relative to the driving synchronous wheel 3 and the driven synchronous wheel 4.

Finally, in view of optimizing the structural design, reducing the manufacturing cost, and improving the reliability and stability of the driving, the driving unit 6 may be structurally designed as follows: the drive section 6 includes a motor/reduction gear box integrated machine 61 and a coupling 62. Wherein, one end of the coupling 62 is connected to the transmission shaft 5, and the other end is connected to the motor reduction gearbox integrated machine 61 (as shown in fig. 2).
