Description

Technical Field

[0001] The utility model relates to a stamping device, in particular to an embossing device for producing laundry tablets. Background Art

[0002] Laundry tablets are a new type of detergent that has emerged in recent years. They highly concentrate effective detergent ingredients, offering higher concentrations and smaller volumes than traditional laundry detergents, making them easier to carry and store. These tablets quickly decompose and dissolve in water, releasing nano-sized cleaning molecules that remove stains from clothing more quickly and thoroughly.

[0003] The production process for laundry tablets generally includes mixing and gelatinization, concentration, and tableting. After tableting, the tablets are in a thin, flake-like shape. Some manufacturers, to enhance the aesthetics of their products, add an embossing process to shape the tablets into a specific shape. Embossing can be achieved through circular cutting and punching. Circular cutting provides a continuous embossing effect, offering extremely high production efficiency. However, the embossed tablets are mixed with waste materials, resulting in a chaotic accumulation and time-consuming collection and sorting. Summary of the Invention

[0004] The utility model provides an embossing device for producing laundry tablets, which solves the problem in the prior art that embossed tablets are disorderly piled up after the embossing process, resulting in a large amount of manpower required for sorting.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: an embossing device for producing laundry tablets, characterized in that it comprises a lower template, a concave mold fixedly arranged on the upper surface of the lower template, a plurality of guide rods vertically fixed relative to the concave mold, an upper template slidably sleeved on the guide rods, and a convex mold fixed on the bottom surface of the upper template, the concave mold being formed from top to bottom with a first cavity, a second cavity and a third cavity penetrating the upper and lower surfaces thereof, and the inner diameter of the cavity is stepped; the embossing device also includes a lifter, a lifting seat and an elastic lifting platform, the elastic lifting platform being located on the upper side of the lifting seat, a spring member and a guide rod being connected between the two, after the lifting seat is driven to be lifted by the lifter, the elastic lifting platform can be pushed into the third cavity and fixed to the top end of the third cavity, and after the lifting seat is driven to be lowered by the lifter, the elastic lifting platform can be moved out from the inside of the third cavity.

[0006] The utility model is a stamping die that can be installed on an existing punch press or other equipment with a reciprocating punching action. The laundry sheet has a soft texture and requires a low punching pressure. The working principle of the utility model is as follows: the upper surface of the die is used to push the laundry sheet body, the punch press drives the upper template to reciprocate up and down along the guide rod, and each time the punch press press press press presses, the punched embossed sheet is pushed onto the elastic lifting platform. As the embossed sheets accumulate, the thickness of the embossed sheets on the elastic lifting platform gradually increases. The size of the second cavity is slightly larger than the size of the embossed sheets, which can have a certain neat effect on the stacking of the embossed sheets without generating a large friction force on the embossed sheets. At the same time, since the stroke of the punch press is fixed and the thickness of the embossed sheets on the elastic lifting platform gradually increases, when the punch press press press press press press press press reaches a preset number of embossed sheets, the punch press press pauses, and the lifting seat is driven by the lifter to descend until the accumulated embossed sheets are completely exposed from the third cavity. Then, the embossed sheets can be manually removed, and the lifting seat is reset to wait for further embossing.

[0007] Furthermore, an air outlet is provided on the bottom surface of the punch, an air inlet is provided on the side surface of the punch, and an air passage connecting the air outlet and the air inlet is provided inside the punch. The air inlet is connected to a high-pressure gas tank. By setting a trigger on the punch press, the switch of the high-pressure gas tank is triggered every time the punch drops to the lowest point, briefly ventilating the air inlet, so that the air outlet can blow off the embossed sheet adhering to the bottom surface of the punch.

[0008] Furthermore, a pusher plate is sleeved on the guide rod, with a return spring connected to the upper mold plate. The pusher plate is provided with a clearance hole that matches the shape of the punch. When the punch is pressed downward, the pusher plate can pre-press the laundry tablet to be punched, securing it. Then, when the punch moves upward and resets, the pusher plate continues to press the tablet, ensuring that the punch can be smoothly separated from the tablet.

[0009] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention can automatically stack embossed sheets on the elastic lifting table, and when the number of embossed sheets stacked reaches a preset number, the elastic lifting table is removed from the third cavity, making it convenient to manually remove the stacked embossed sheets.

The guide rods are sleeved with guide sleeves 31, which are fixed to the upper template. The lower template has four die sets arranged in a straight line array, and four punches. The die set has a first cavity 21, a second cavity 22, and a third cavity 23 extending from top to bottom, and the inner diameter of the cavity is stepped. The embossing device also includes a lifter 60 and a lift seat 70. And an elastic lifting platform 80, there are four elastic lifting platforms and they correspond one to one with the die, the lifter is an electric cylinder arranged vertically upward, the elastic lifting platform is located on the upper side of the lifting seat, and four spring parts 81 and four guide rods 82 are connected between the two, the guide rods are vertically fixed to the bottom of the elastic lifting platform, the lower ends of the guide rods are passed through the lifting seat, the spring parts are sleeved on the guide rods, and the lower ends of the guide rods are fixed with a limiting cap 83, after the lifting seat is driven to be lifted by the lifter, the elastic lifting platform can be pushed into the third cavity and fixed to the top of the third cavity, after the lifting seat is driven to be lowered by the lifter, the elastic lifting platform can be moved out from the inside of the third cavity.

[0017] See Figure 1The bottom surface of the punch is provided with an air outlet 51, the side surface of the punch is provided with an air inlet 52, and the inside of the punch is provided with an air duct 53 connecting the air outlet and the air inlet. The air inlet is connected to the high-pressure gas tank. By setting a trigger development on the punch press, the switch of the high-pressure gas tank can be triggered every time the punch drops to the lowest point, and the air inlet is briefly ventilated, so that the air outlet can blow off the embossed sheet adhering to the bottom surface of the punch.

[0018] See Figure 1 and Figure 4 The guide rod is also equipped with a push plate 90, and a return spring 91 is connected between the push plate and the upper mold plate. The push plate is provided with an avoidance hole 92 that matches the shape of the punch. When the punch is pressed down, the push plate can be pressed against the laundry tablet to be punched in advance, playing a fixing role.

[0019] This embodiment is a stamping die that can be installed on an existing punch press or other equipment with a reciprocating punching action. The laundry tablets are soft in texture and require less punching pressure. The working principle of this embodiment is as follows: the upper surface of the die is used to push the laundry tablet body, and the punch press drives the upper template to punch up and down along the guide rod. Each time the punch press presses, the punched embossed tablets are pushed onto the elastic lifting platform. As the embossed tablets accumulate, the thickness of the embossed tablets on the elastic lifting platform gradually increases. The size of the second cavity is slightly larger than the size of the embossed tablets, which can provide a certain degree of alignment for the stacking of the embossed tablets without generating significant friction. At the same time, because the stroke of the punch is fixed, while the thickness of the embossed tablets on the elastic lifting platform gradually increases, when the punch press presses against the embossed tablets on the elastic lifting platform, the elastic lifting platform will adaptively sink. When the number of embossed tablets accumulated reaches a preset number, the punch press pauses, and the lifting seat is driven down by the elevator until the accumulated embossed tablets are completely exposed from the third cavity. The embossed tablets can then be manually removed, and the lifting seat finally returns to its original position and waits for further embossing.
