Description

Technical Field

[0001] The invention belongs to the technical field of printing and processing, and relates to a cup ironing machine, in particular to a feeding mechanism of the cup ironing machine. Background Art

[0002] Hot stamping is a special printing process that does not use ink. Hot stamping refers to the process of hot stamping aluminum foil onto the surface of the substrate under a certain temperature and pressure. The hot stamping machine is the equipment that completes the hot stamping process. Common substrates include plastic plates, plastic cups and plastic saucers.

[0003] Existing hot stamping machines generally include a feeding mechanism and a hot stamping mechanism. A large number of substrates are placed on the feeding mechanism, and the feeding mechanism transports the substrates to the hot stamping mechanism one by one. Since the shapes of various types of substrates are different, the specific structure of the feeding mechanism is designed according to the type of substrate. When hot stamping plastic cups, a receiving channel for placing plastic cups will be designed in the feeding mechanism. The size of the receiving channel is designed according to the size of the plastic cups. After the plastic cups are placed in the receiving channel, the receiving channel limits the plastic cups, so the receiving channel can only accommodate plastic cups of one size. However, in the actual production process, there are many types of plastic cups, and the sizes of plastic cups vary. Plastic cups of different sizes must correspond to different feeding mechanisms, and the versatility of the feeding mechanism is poor. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems in the prior art and to propose a feeding mechanism for a cup hotting machine. The technical problem to be solved by the present invention is: how to improve the versatility of the feeding mechanism.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] 14. The cup-scalding machine according to claim 13, wherein the first and second ends of the cup-scalding plate are provided with a plurality of limit posts, the limit posts being arranged along the length direction of the cup-scaling plate, the plurality of left and right connecting plates being fixed to the cup-scaling plate, the plurality of right and left connecting plates being fixed to the cup-scaling plate, the plurality of right and left connecting plates being fixed to the cup-scaling plate, the plurality of right and left connecting plates being fixed to the cup-scaling plate, the plurality of right and left connecting plates being fixed to the cup-scaling plate, the plurality of right and left connecting plates being fixed to the cup-scaling plate, the plurality of right and left connecting plates being fixed to the cup-scaling plate, the plurality of

[0007] In the feeding mechanism, the limiting column fixedly connected to the expansion plate, the limiting column fixedly connected to the two left connecting plates and the limiting column fixedly connected to the two right connecting plates together constitute an accommodating channel for placing the plastic cup. After the plastic cup is placed in the accommodating channel, the limiting column fixedly connected to the expansion plate is used to support and lift the plastic cup, the limiting column fixedly connected to the two left connecting plates limits the left side of the plastic cup, and the limiting column fixedly connected to the two right connecting plates limits the right side of the plastic cup. The plastic cup can slide downward along the limiting column under the action of its own gravity, which is convenient for loading the cup hot machine; in the structure, the gear can be driven to rotate by rotating the hand wheel, and the two racks can move relative to each other after the gear rotates, and the two racks can approach or move away from each other, thereby making the left connecting plate and the right connecting plate approach or move away from each other, making the limiting column on the left and the limiting column on the right approach or move away from each other, and realizing that the spacing between the limiting column on the left and the limiting column on the right is adjustable, so as to accommodate plastic cups of various sizes, thereby improving the versatility of the feeding mechanism.

[0008] In the feeding mechanism of a cup hot machine, a vibration cylinder is fixed near the upper end of the cup feeding plate, a pull shaft arranged in the transverse direction is fixed on the piston rod of the vibration cylinder, a vibration pull seat is hinged on the pull shaft, and the vibration pull seat is fixedly connected to the limit column on the expansion plate. Through the setting of this structure, a number of plastic cups are placed in the accommodating channel formed by all limit columns, and adjacent plastic cups are plugged together in sequence. Due to the excessive number of plastic cups, some plastic cups are stuck. The piston rod of the vibration cylinder is rapidly extended and retracted with a small amplitude, and the limit column is driven to vibrate through the pull shaft and the vibration pull seat, ensuring that each plastic cup can slide along the limit column to the lower end of the cup feeding plate.

[0009] In the above-mentioned feeding mechanism of a cup hot machine, the feeding mechanism also includes a mounting frame and a base plate, the base plate is arranged parallel to the cup feeding plate, the cup feeding plate is connected to the base plate, the lower end of the base plate is hinged on the mounting frame, the outer side wall of the base plate is provided with a guide groove along its length direction, the mounting frame is provided with a vertically arranged strip hole, a sliding rod is vertically slidably arranged in the strip hole, one end of the sliding rod is located in the guide groove, a cross beam is arranged on the mounting frame, an adjusting nut is arranged on the cross beam and the adjusting nut can rotate circumferentially, a lifting screw rod is screwed on the adjusting nut, and the upper end of the lifting screw rod is fixedly connected to the base plate. Since plastic cups are of different sizes, their weights are also different. Small-sized cups are light, while large-sized cups are heavy. When the cup is lighter, the inclination of the cup-delivering plate needs to be increased so that the cup can slide smoothly to the lower end of the cup-delivering plate along the limiting column. When the cup is heavier, the inclination of the cup-delivering plate needs to be decreased. Through the arrangement of the present structure, the adjusting nut is rotated so that the adjusting nut rotates circumferentially on the crossbeam, thereby driving the lifting screw rod to rise and fall vertically, so that the lower end of the bottom plate rotates around the mounting frame, and the sliding rod slides along the guide groove while rising and falling in the strip hole. The upper end of the bottom plate rises or falls, thereby realizing the adjustment of the inclination of the cup-delivering plate to meet the sliding requirements of cups of different weights.

[0010] In the feeding mechanism of the above cup hot machine, a cylinder is provided on the left connecting plate and the right connecting plate at the lower end of the cup feeding plate, a push plate is fixed on the piston rod of the cylinder and the cylinder can drive the push plate to move along the width direction of the cup feeding plate, and the two push plates are provided with limiting grooves on the opposite sides. Through the setting of this structure, the cylinder drives the two push plates to approach each other, and the two push plates are against the outer wall of the plastic cup to prevent the plastic cup from sliding off the lower end of the cup feeding plate, and the limiting groove fits with the outer wall of the plastic cup to better limit the plastic cup.

[0011] In the feeding mechanism of the above cup hot machine, a frame is fixed at the lower end of the cup feeding plate, and a fat clamping cylinder is arranged on the top of the frame, and the fat clamping cylinder is located above the expansion plate. Through the arrangement of this structure, several plastic cups are plugged and connected in sequence. First, the two push plates clamp the bottommost plastic cup in place, and the fat clamping cylinder clamps the second to last plastic cup in place. When the external manipulator takes away the bottommost plastic cup, the fat clamping cylinder releases the plastic cup so that all the plastic cups slide down a certain distance. The bottommost plastic cup is clamped in place by the two push plates, and the fat clamping cylinder clamps the second to last plastic cup in place. And so on, stable feeding of plastic cups is achieved.

[0012] Compared with the prior art, the feeding mechanism of the cup hot machine of the present invention has the following advantages: in this structure, the gear can be driven to rotate by rotating the hand wheel, and the two racks can move relative to each other after the gear rotates, and the two racks can move closer to or farther from each other, thereby making the left connecting plate and the right connecting plate closer to or farther from each other, making the limiting column on the left side and the limiting column on the right side closer to or farther from each other, and realizing that the distance between the limiting column on the left side and the limiting column on the right side is adjustable so as to accommodate plastic cups of various sizes, thereby improving the versatility of the feeding mechanism.
