DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] An embodiment of a drying device for producing a watch protective film of the present invention is used to dry a circular watch protective film 600, such as Figures 1 to 6 As shown, it includes a drying box 100, a driving crawler 200 and a drying rack 300.

[0027] The drying rack 300 is placed on the transmission crawler 200, and the transmission crawler 200 rotates to send the drying rack 300 into or out of the drying box 100; wherein, the drying box 100 and the transmission crawler 200 are both common structures in the prior art, and their specific structures are not described in detail.

[0028] The drying rack 300 includes two frames with the same structure, each frame includes a base frame 310, a partition column 320 and a telescopic rod 330; there are at least two partition columns 320, and they are all arranged in parallel. Each partition column 320 is horizontally arranged and fixed to the base frame 310. At least two partition columns 320 define a support space for placing a watch protective film 600, and multiple watch protective films 600 are distributed in sequence along the axial direction of the partition columns 320; preferably, each frame has two partition columns 320, and the distance between the two partition columns 320 is not greater than the diameter of the watch protective film 600, so that the two sides of the watch protective film 600 can be supported on the two partition columns 320 respectively. One end of the telescopic rod 330 is installed on the base frame 310 and is perpendicular to the axial direction of the partition column 320; a first elastic member (not shown in the figure) is arranged inside the telescopic rod 330, and the length of the telescopic rod 330 is adjustable and can be locked after adjustment; specifically, the telescopic rod 330 includes an outer rod 331, an inner rod 332 and a screw (not shown in the figure), and one end of the inner rod 332 is slidably connected to the outer rod 331; the first elastic member is a first spring, and is arranged in the outer rod 331 and connects the outer rod 331 and the inner rod 332; the screw is installed on the outer rod 331, and can be rotated to abut against the inner rod 332, thereby locking the inner rod 332 and the outer rod 331. The two frames are an upper frame 400 and a lower frame 500. The base frame 310 of the lower frame 500 is placed on the transmission track 200. After the watch protective film 600 is placed on at least two partition columns 320 of the lower frame 500, the upper frame 400 is symmetrically inverted on the upper side of the watch protective film 600, and the other ends of the telescopic rods 330 of the two frames are hinged around a hinge axis parallel to the axis of the partition column 320; and the upper frame 400 and the lower frame 500 are connected by a second elastic member (not shown in the figure), the second elastic member causes the telescopic rods 330 of the two frames to be coaxial, and allows the upper frame 400 to rotate relative to the lower frame 500 around the hinge axis of the two telescopic rods 330 within a preset range. After the telescopic rods 330 of the two frames are hinged, the upper frame 400 is pressed downward to shrink the telescopic rods 330 of the two frames until at least two partition columns 320 of the upper frame 400 can limit the watch protective film 600, that is, at least two partition columns 320 of the upper frame 400 are lower than the upper end of the watch protective film 600, and are respectively located on both sides of the watch protective film 600, and define a space that prevents the watch protective film 600 from detaching with at least two partition columns 320 of the lower frame 500. Then the length of the telescopic rod 330 is locked. Among them, the preset range depends on the stiffness coefficient of the second elastic member. The larger the stiffness coefficient of the second elastic member, the smaller the swing range of the upper frame 400 relative to the lower frame 500, and the smaller the stiffness coefficient of the second elastic member, the larger the swing range of the upper frame 400 relative to the lower frame 500.

[0029] Two frames are set to limit the watch protective film 600. When the drying rack 300 moves with the transmission belt 200, the unevenness of the movement of the transmission belt 200 is used to make the upper frame 400 swing relative to the lower frame 500 under the action of inertia, thereby changing the relative position of the partition columns 320 of the upper frame 400 and the watch protective film 600. When the annular space defined by the multiple partition columns 320 of the upper frame 400 and the lower frame 500 is not coaxial with the watch protective film 600, the partition columns 320 of the upper frame 400 will drive the watch protective film 600 to rotate slightly when swinging, thereby changing the relative position of the partition columns 320 of the lower frame 500 and the watch protective film 600, thereby improving the drying effect of the outer peripheral wall of the watch protective film 600.

[0030] In this embodiment, the telescopic rods 330 of the two frames are compressed until their hinge axes are coaxial with the center of the watch protective film 600, and the length of the telescopic rods 330 of the two frames is locked. At this time, the multiple partitioning columns 320 of the two frames are in contact with the watch protective film 600, and the hinge points of the telescopic rods 330 of the two frames are coaxial with the center of the watch protective film 600. The partitioning columns 320 of the two frames hold the watch protective film 600 most stably, but when the upper frame 400 swings relative to the lower frame 500, it can only change the relative position of the partitioning columns 320 of the upper frame 400 and the watch protective film 600, and the drying effect of the abutment position of the partitioning columns 320 of the lower frame 500 is poor. In some other embodiments, when the telescopic rods 330 of the two frames are compressed until their hinge axes are coaxial with the center of the watch protective film 600, the length of the telescopic rod 330 of the lower frame 500 is locked, and the length of the telescopic rod 330 of the upper frame 400 is locked after allowing the telescopic rod 330 of the upper frame 400 to extend to a preset length. Among them, the preset extension length of the telescopic rod 330 of the upper frame 400 is relatively small, so that a small gap is generated between the partition column 320 of the upper frame 400 and the watch protective film 600. At this time, only the partition column 320 of the lower frame 500 is in contact with the watch protective film 600. When the upper frame 400 swings relative to the lower frame 500, the relative position of the partition column 320 of the upper frame 400 and the watch protective film 600 will change, and during the swinging process, one of the partition columns 320 will be in contact with the watch protective film 600, thereby driving the watch protective film 600 to rotate slightly, thereby changing the contact position of the watch protective film 600 and the partition column 320 of the lower frame 500, and further improving the drying effect of the outer wall of the watch protective film 600.

[0031] In this embodiment, the second elastic member is a torsion spring connecting the hinged ends of the two telescopic rods 330, one end of the torsion spring is installed at the end of the telescopic rod 330 of the lower frame 500, and after the telescopic rod 330 of the lower frame 500 is hinged with the telescopic rod 330 of the upper frame 400, the other end of the torsion spring is connected to the end of the telescopic rod 330 of the upper frame 400. When the base frame 310 of the lower frame 500 is placed on the driving crawler 200, the telescopic rod 330 of the lower frame 500 extends vertically, and the torsion spring causes the telescopic rod 330 of the upper frame 400 to be coaxial with the telescopic rod 330 of the lower frame 500. In some other embodiments, the second elastic member is a plurality of second springs, which all extend along the length direction of the telescopic rod 330 and are distributed around the circumference of the base frame 310, and each second spring is connected to the base frames 310 of the two frames, and the lower end of the second spring is connected to the base frame 310 of the lower frame 500, and the upper frame 400 and the telescopic rod 330 of the upper frame 400 are hinged to connect the upper end of the second spring to the base frame 310 of the upper frame 400; the second spring can provide stable support for the upper frame 400, and also allow the upper frame 400 to swing slightly relative to the lower frame 500.

[0032] In this embodiment, a plurality of limiting grooves 321 are spaced apart along the axial direction of the partition column 320, and the limiting grooves 321 are perpendicular to the evenly inclined surfaces of the two side walls of the partition column 320 in the axial direction, and are used to guide the watch protective film 600 to cooperate with the limiting grooves 321. The limiting grooves 321 on the plurality of partition columns 320 of the two frames correspond one to one, and the outer peripheral wall of each watch protective film 600 corresponds to the limiting grooves 321 of the plurality of partition columns 320, respectively.

[0033] In this embodiment, the base frame 310 includes two bases 311 and a connecting rod 312 connecting the two bases 311, and the connecting rod 312 is located on the side of the base 311 away from the watch protective film 600; the two bases 311 are distributed in sequence along the axial direction of the partition column 320, and the two ends of the partition column 320 are respectively installed on the two bases 311; each frame has two telescopic rods 330, which are respectively installed on the two bases 311. The connecting rod 312 is composed of two arc-shaped rods, which are arranged back to back and connected in the middle, and the two ends of each arc-shaped rod are connected to the two bases 311. The connection positions of the two arc-shaped rods on the two bases 311 are distributed in a matrix, so that the base frame 310 can provide stable support for the partition column 320 while minimizing the shielding of the base frame 310 on the watch protective film 600, so that the watch protective film 600 is more fully in contact with the hot air of the drying box 100.

[0034] When using the drying device for producing a watch protective film of the present invention, the watch protective film 600 is first placed vertically and supported in sequence on the limiting grooves 321 on the multiple partition columns 320 of the lower frame 500, and then the upper frame 400 is buckled on the lower frame 500 in a symmetrical state with the lower frame 500, and the telescopic rod 330 of the upper frame 400 is hinged with the telescopic rod 330 of the lower frame 500, and then the two frames are connected by a second elastic member. In the initial state, the telescopic rods 330 of the two frames are in a freely retractable state, and the telescopic rod 330 of the lower frame 500 is in a vertical state. Under the action of the second elastic member, the telescopic rod 330 of the upper frame 400 is coaxial with the telescopic rod 330 of the lower frame 500, and both are in a vertical state. Then, the upper frame 400 is pressed down to shrink the telescopic rods 330 of the two frames, and the hinge points of the two telescopic rods 330 are moved down until the partition column 320 of the upper frame 400 abuts or is about to abut against the outer peripheral wall of the watch protective film 600, and then the length of the telescopic rods 330 of the two frames is locked. Then, the entire drying rack 300 is placed on the transmission crawler 200, so that the transmission crawler 200 sends it into the drying box 100 for drying. In order to ensure the drying effect of the drying box 100, a plurality of drying stations are generally arranged in the drying box 100. When the transmission track 200 transports the drying rack 300 from one station to another, the drying rack 300 will vibrate when starting and stopping, thereby causing the upper frame 400 to swing relative to the lower frame 500, thereby changing the relative position of the partition column 320 of the upper frame 400 and the watch protective film 600, or further changing the relative position of the partition column 320 of the lower frame 500 and the watch protective film 600, thereby improving the drying effect of the watch protective film 600.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
