Description

Technical Field

[0001] The utility model belongs to the field of plastic product processing, in particular to a plastic product hot stamping device. Background Art

[0002] Plastic hot stamping is a commonly used surface treatment process that transfers metal foil to the plastic surface by heating and applying a certain amount of pressure on the surface of plastic products to increase the texture and visual effect of the product.

[0003] According to a publicly disclosed surface hot stamping device for plastic products (Announcement No.: CN 216153380U), it includes a workbench, fixed plates are fixed on both sides of one side of the top of the workbench, and two limiting rollers are rotatably connected between the two fixed plates, vertical plates are fixed on both sides of the middle part of the top of the workbench, the tops of the two vertical plates are fixedly connected to support plates, an electric hydraulic cylinder is fixed on the middle part of the top of the support plate, and a connecting sleeve is sleeved on the telescopic end of the electric hydraulic cylinder. The beneficial effects of this utility model are as follows: three card needles can cooperate with three card slots to pierce the waste paper, and the gasket can be pressed against one side of one of the slide rails by the fixing nut, so that the screw can be fixed, thereby fixing the position of the pressing block and then fixing the waste paper; the two limiting rollers can limit the height of the roll of paper carrying the gold foil, making it more stable during the hot stamping process, and the hot stamping plate can be easily replaced by the connecting sleeve provided on the top of the hot stamping plate;

[0004] The above application fixes an electric hydraulic cylinder in the middle of the top of the support plate, and the telescopic end of the electric hydraulic cylinder is sleeved with a connecting sleeve assembly, which makes it impossible to automatically push out the plastic products that have been hot stamped. After completing the hot stamping work of a plastic product, it is necessary to manually turn the winding roller to reel up a part of the hot stamping paper, and then perform the hot stamping work on the next plastic product. Therefore, it is necessary to manually pick up and operate it. The degree of automation is low, which increases the workload. Therefore, we propose a hot stamping device for plastic products. Utility Model Content

[0005] The purpose of the utility model is to provide a device for hot stamping of plastic products, which cooperates with the threaded rotating rod, threaded sleeve, push strip, hydraulic cylinder, force rod, hydraulic rod, positioning plate, limit plate and other components inside the positioning device through the rotation of the motor output shaft, so that when the threaded rotating rod rotates counterclockwise, it will drive the threaded sleeve to move forward, and when the threaded sleeve moves forward, it will drive the push strip to move forward. When the push strip moves forward, it will push the force rod to move into the hydraulic cylinder. When the force rod moves into the hydraulic cylinder, the hydraulic rod will move outward due to the force of the force rod moving into the hydraulic cylinder. When the hydraulic rod moves outward, it will drive the positioning plate to move outward, so as to achieve the purpose of positioning the plastic product by using the limit plate on the moving mechanism, thereby preventing the plastic product from being displaced during hot stamping, and solving the existing problems.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a hot stamping device for plastic products, comprising a workbench, a fixed plate fixedly connected to the top of the workbench, a moving mechanism provided on the top of the workbench, a hot stamping device provided on the front side of the fixed plate, a feeding device provided on the top of the workbench, an electric telescopic rod fixedly connected to the top of the moving mechanism, a limit plate fixedly connected to the top of the moving mechanism, and a positioning device provided on the top of the workbench;

[0009] Furthermore, a return spring is fixedly connected to the circumferential surface of the force-bearing rod, and one end of the return spring away from the force-bearing rod is fixedly connected to the back side of the hydraulic cylinder. The function of the return spring is to allow the force-bearing rod to be reset by the return spring when the push bar no longer pushes the force-bearing rod.

[0010] Furthermore, the front side of the motor is fixedly connected to a limiting rod, the circumferential surface of the limiting rod passes through the front side of the threaded sleeve, and the circumferential surface of the limiting rod is slidably connected to the inner wall of the threaded sleeve. The function of the limiting rod is to limit the movement trajectory of the threaded sleeve.

[0011] Furthermore, a sprocket one is fixedly passed through the circumferential surface of the threaded rotating rod, a chain is engaged with the circumferential surface of the sprocket one, a sprocket two is engaged with the inner wall of the chain, a rotating shaft is fixedly connected to the back side of the sprocket two, a support plate is rotatably connected to the back side of the rotating shaft, and the bottom of the support plate is fixedly connected to the top of the workbench. The function of the chain is to drive the sprocket two to rotate, and the function of the rotating shaft is to drive the gear to rotate.

[0012] Furthermore, a gear is fixedly passed through the circumferential surface of the rotating shaft, a rack is slidably connected to the top of the workbench, and an L-shaped rod is fixedly connected to the side of the rack. The function of the gear is to push the rack to move.

[0013] Furthermore, a push plate is fixedly connected to the side of the L-shaped rod, and a receiving plate is fixedly connected to the bottom of the moving mechanism.

[0014] Furthermore, the back side surface of the force-bearing rod is located on the displacement trajectory of the push bar, and the circumferential surface of the gear is engaged with the top of the rack. The purpose of the back side surface of the force-bearing rod being located on the displacement trajectory of the push bar is to push the force-bearing rod when the push bar moves, and the purpose of the circumferential surface of the gear being engaged with the top of the rack is to push the rack to move when the gear rotates.

[0015] The utility model has the following beneficial effects:

[0016] The utility model realizes that when the threaded rotating rod rotates counterclockwise, it drives the threaded sleeve to move forward, and when the threaded sleeve moves forward, it drives the pushing bar to move forward. When the pushing bar moves forward, it pushes the force-bearing rod to move into the hydraulic cylinder. When the force-bearing rod moves into the hydraulic cylinder, the hydraulic rod will move outward due to the force of the force-bearing rod moving into the hydraulic cylinder. When the hydraulic rod moves outward, it will drive the positioning plate to move outward, so that when the pushing plate moves to the left, the plastic product with the hot stamping completed on the moving mechanism can be pushed into the receiving plate, thereby completing the automatic unloading of the finished product and improving the degree of automation of the hot stamping processing of plastic products. The plastic product can be positioned by utilizing the limiting plate and the movable positioning plate on the moving mechanism, thereby preventing the plastic product from being displaced during hot stamping.
