[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 The present invention provides a dyeing device for plastic products, comprising:

[0029] A base 1, a belt conveyor 2 and a support frame 3 are installed on the top of the base 1, a dye box 4 is fixedly installed on the top of the support frame 3, and a pump body 5 is connected to both sides of the dye box 4;

[0030] The dyeing range adjustment component 6 is arranged inside the support frame 3. The dyeing range adjustment component 6 includes a dyeing range track 601. The front and rear sides of the inner cavity of the support frame 3 are both equipped with dyeing range tracks 601. The inner cavity of the dyeing range track 601 is slidably connected with a movable soft seat 603. The front and rear sides of the movable soft seat 603 are provided with a movable groove 604. The top of the dyeing range track 601 is fixedly installed with a track plate 602 located in the inner cavity of the movable groove 604. The top of the inner cavity of the support frame 3 is fixedly installed with a motor 605. The output shaft of the motor 605 is fixedly installed with a first rotating plate 606. Both sides of the first rotating plate 606 are rotatably connected with the first connecting plate 607. One side of the first connecting plate 607 is rotatably connected with a connecting block 608. One side of the connecting block 608 is connected to the movable soft seat 603. A diverter hose 11 is fixedly sleeved on the movable soft seat 603. The bottom of the diverter hose 11 is fixedly installed with a nozzle 9. The top of the diverter hose 11 is connected with a delivery hose 10. The output end of the pump body 5 is connected to the delivery hose 10.

[0031] The first rotating plate 606 is driven by the motor 605 to rotate. Since the connecting block 608 and the first rotating plate 606 are connected by the first connecting plate 607, when the first rotating plate 606 rotates, it can drive the movable soft seat 603 to move along the inner cavity of the dyeing range track 601, so as to facilitate the adjustment of the position of the movable soft seat 603 in the dyeing range track 601, thereby adjusting the position of the movable soft seat 603 and the nozzle 9 on the two dyeing range tracks 601, so that the two movable soft seats 603 move in opposite directions, which is convenient for adjusting the entire dyeing range according to the size of the plastic product, thereby improving the practicality of this device.

[0032] In one embodiment of the present invention, the dyeing range adjustment assembly 6 further includes a memory metal strip 609 fixedly mounted on the inner wall of the movable groove 604 and in contact with the track plate 602. The memory metal strip 609 facilitates the movement of the movable soft seat 603 within the dyeing range track 601.

[0033] In one embodiment of the present invention, both sides of the dyeing range track 601 are bent downward into an arc shape. This shape facilitates the movement of the soft seat 603 to the side of the dyeing range track 601, forming an inclined shape. This facilitates dyeing plastic products that require side dyeing, making the device suitable for dyeing plastic products of various shapes.

[0034] In one embodiment of the present invention, the inner cavity of the support frame 3 is provided with a plastic product positioning and adjustment component 7, which includes a second rotating plate 701, a second connecting plate 702, a support rod 703, a movable plate 704 and a positioning plate 705. The output end of the motor 605 is connected to the second rotating plate 701, and both sides of the second rotating plate 701 are rotatably connected to the second connecting plate 702. The bottom of the second connecting plate 702 is rotatably connected to the support rod 703. The bottom of the support rod 703 is fixedly installed with a positioning plate 705, and the side of the positioning plate 705 is fixedly installed with a movable plate 704. The movable plate 704 is movably sleeved on the support frame 3.

[0035] When the motor 605 drives the first rotating plate 606 to rotate and adjust the position of the movable soft seat 603, it can drive the second rotating plate 701 to rotate. Through the rotation of the second rotating plate 701, the second connecting plate 702 drives the support rod 703, the positioning plate 705 and the movable plate 704 to move along the connection between the movable plate 704 and the support frame 3, thereby adjusting the distance between the two positioning plates 705. When the dyeing range becomes wider, the two positioning plates 705 can be driven to move toward the outside, which is convenient for changing the range of the positioning plate 705 for positioning plastic products.

[0036] In one embodiment of the present invention, the front side of the positioning plate 705 is tilted toward the outside, and the two positioning plates 705 are symmetrically distributed. The shape of the positioning plates 705 is used to facilitate the plastic product to enter between the two positioning plates 705, so that the plastic product can be sprayed in the center.

[0037] In one embodiment of the present invention, there are multiple movable plates 704, and the multiple movable plates 704 are distributed along the outer side of the positioning plate 705. The multiple movable plates 704 improve the stability of the movement of the positioning plate 705.

[0038] In one embodiment of the present invention, a splash-proof assembly 8 is provided on the positioning plate 705. The splash-proof assembly 8 includes a receiving slot 801, a telescopic rod 802, a baffle 803, and a spring 804. The top of the positioning plate 705 is provided with a receiving slot 801, a telescopic rod 802 is mounted at the bottom of the inner cavity of the receiving slot 801, a baffle 803 is fixedly mounted on the top of the telescopic rod 802, a spring 804 is movably sleeved on the outer side of the telescopic rod 802, and the ends of the spring 804 are respectively mounted on the positioning plate 705 and the baffle 803. The baffle 803 provided on the positioning plate 705 increases the height of the side shielding. The baffle 803 connected to the positioning plate 705 by the telescopic rod 802 and the spring 804 facilitates shielding of plastic products during dyeing, preventing dye from splashing and affecting the surrounding environment of the device.

[0039] In one embodiment of the present invention, the bottom of baffle 803 is provided with a plurality of telescopic rods 802 and springs 804, which are evenly distributed within storage slot 801. The provision of the plurality of telescopic rods 802 and springs 804 facilitates downward movement of positioning plate 705 when it encounters the bend of dyeing range track 601 while moving outward, thereby ensuring that baffle 803 does not interfere with the dyeing of plastic products.

[0040] Working principle: When using this device, according to the size of the plastic product to be dyed, the motor 605 is used as a drive to drive the first rotating plate 606 to rotate. Since the connecting block 608 and the first rotating plate 606 are connected by the first connecting plate 607, when the first rotating plate 606 rotates, it can drive the movable soft seat 603 to move along the inner cavity of the dyeing range track 601, and adjust the position of the movable soft seat 603 in the dyeing range track 601, thereby adjusting the positions of the movable soft seats 603 and the nozzle 9 on the two dyeing range tracks 601, so that the two movable soft seats 603 move in opposite directions, and the entire dyeing range is adjusted according to the size of the plastic product;

[0041] When the motor 605 drives the first rotating plate 606 to rotate and adjust the position of the movable soft seat 603, it can drive the second rotating plate 701 to rotate. Through the rotation of the second rotating plate 701, the second connecting plate 702 drives the support rod 703, the positioning plate 705 and the movable plate 704 to move along the connection between the movable plate 704 and the support frame 3, thereby adjusting the distance between the two positioning plates 705. When the dyeing range becomes wider or narrower, the two positioning plates 705 can be driven to move in opposite directions, changing the range of the positioning plates 705 for positioning the plastic products, and better adjusting the distance between the two positioning plates 705.

[0042] The plastic product to be dyed is placed on the belt conveyor 2. The belt conveyor 2 transports the plastic product through the front bent portion of the positioning plate 705, so that the plastic product is pushed to the middle of the belt conveyor 2 for movement. When the plastic product passes under the nozzle 9, the pump body 5 is used to spray the dye in the dye box 4 through the delivery hose 10 and the diversion hose 11 from the nozzle 9 onto the plastic product, thereby completing the dyeing of the plastic product.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
