The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0021] See also Figure 1-6 The utility model provides an embodiment: a junction box spraying device, comprising a spray frame 1 and a movable frame 3 slidably matched with the spray frame 1; the spray frame 1 comprises a support frame 10, one end of the support frame 10 is connected to a guide frame 12, and a slide groove 11 for guiding the sliding of the movable frame 3 is provided on the guide frame 12; the support frame 10 is also provided with a fixing hole 15, and a feed pipe 14 is installed on the fixing hole 15, and a mounting hole 17 for installing a nozzle is provided on the feed pipe 14; the movable frame 3 comprises a connecting rod 33 for connecting to the junction box, and the upper end of the connecting rod 33 is provided with a slide rod 32 sliding in the slide groove 11.

[0022] In summary, after the junction box passes through the feed pipe 14, the nozzle sprays the plastic powder onto the three surfaces of the junction box at the same time, namely, the bottom surface and the two side surfaces adjacent to the bottom surface and facing the nozzle; after the movable frame 3 moves from the left side to the right side, namely, after completely passing through the feed pipe 14, the movable frame 3 is rotated to turn the two unsprayed surfaces to face the nozzle, and then move from right to left to complete the spraying operation on the remaining two surfaces of the junction box. Based on this, the spraying of each surface of the junction box can be completed by sliding, which can improve the spraying efficiency of the junction box and prevent the phenomenon of plastic powder falling during the rotation of the junction box.

[0023] In addition, the junction box after spraying can be moved to the heating furnace by the handheld mobile frame 3, so that the junction box does not come into contact with the user's hands during the spraying and curing process, thereby improving the spraying quality of the junction box. The specific structure of the feed pipe 14 is as follows: the feed pipe 14 consists of a horizontal pipe and vertical pipes at both ends of the horizontal pipe; the horizontal pipe is horizontally placed on the bottom surface of the junction box, and the vertical pipe is vertically placed on the two sides of the junction box, so that the junction box can be sprayed on three surfaces at the same time after passing through.

[0024] At the same time, since the spraying frame 1 is installed in the provided bottom box 2, the bottom box 2 can be used to collect the overflowing plastic powder, which can reduce the pollution of the plastic powder to the work station and reduce the waste of plastic.

[0025] Specifically, the support frame 10 is connected to the bottom box 2 via a base 13, so the base 13 can be used to press the bottom box 2 on the work station to avoid displacement of the bottom box 2, so as to improve the stability of the spraying frame 1 and the bottom box 2 during use. In addition, the base 13 can be a cement block, an iron block, or a lead block, etc., wherein the feed pipe 14 is threadedly matched with the fixing hole 15 via a bolt 16, and the other side of the fixing hole 15 is connected to an external pipeline to ensure a continuous supply of plastic powder.

[0026] On the basis of the above scheme, since the sliding rod 32 is slidably matched with the sliding groove 11 through the sliding member 31, and the sliding rod 32 is connected with the handle 30 through the sliding member 31, the sliding member 31 is used to guide the sliding rod 32 to slide stably, and the handle 30 is convenient for the user to make the sliding rod 32 slide and lift the sliding rod 32.

[0027] Specifically, the sliding member 31 includes a support portion 35 that fits in the slide groove 11, and one end of the support portion 35 slides on the upper surface of the guide frame 12 through a first baffle 34. Therefore, the sliding member 31 can be prevented from falling off;

[0028] At the same time, the other end of the support portion 35 slides on the lower surface of the guide frame 12 through the second baffle 37, thereby preventing the sliding member 31 from moving upward in the sliding groove 11 when the user causes the sliding rod 32 to slide, thereby preventing the sliding member 31 from working unstably, resulting in an unstable gap between the bottom surface of the junction box and the nozzle, and affecting the spraying quality.

[0029] Furthermore, since the handle 30 is connected to the slot 36 provided on the first baffle 34 through the provided latch 39, the problem of the slide bar 32 rotating along its central axis can be avoided when the latch 39 cooperates with the slot 36, thereby ensuring that the distance between the two sides of the junction box and the nozzle is constant. In addition, since the latch 39 and the slot 36 are both cross-shaped, when rotation is required, the slide bar 32 is lifted upward to completely separate the latch 39 from the slot 36, and then rotated 90 degrees, and then the latch 39 is inserted into the slot 36, so that the junction box adjustment is not affected and the gap between the junction box and the nozzle after adjustment can be ensured to be constant.

[0030] Since a ring 38 is provided at the upper end of the handle 30, it is convenient for the user to cause the slide rod 32 to rotate along its central axis and lift it upward along its central axis. At the same time, the lower end of the handle 30 is threadedly connected to the end of the slide rod 32 through an external threaded column 310, which makes the installation and disassembly of the handle 30 simple and convenient.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
