Description

PAPER RECYCLING MACHINE FOR THE MANUFACTURE OF OBJECTS OBJECT OF THE INVENTION The present invention relates to a recycling and object-shaping machine designed to transform household paper and cardboard waste into molded products such as toys, decorations, or utensils through a semi-automatic process that combines shredding, pulping, pressing, and drying. This compact machine, suitable for home or educational use, promotes sustainability and creativity by converting everyday waste into useful or playful objects. Currently, household management of paper and cardboard waste faces several limitations. Although recycling is an increasingly promoted practice, the actual process at home is hampered by a lack of accessible tools to transform this waste into new products. Most of this waste ends up in the regular trash or recycling bin without providing any educational or practical experience. One of the main problems is the lack of suitable equipment for small-scale recycling. Existing systems are large, expensive, and designed for industrial use, making them impractical for homes or schools. Meanwhile, traditional home techniques like shredding, soaking, and manual molding are impractical, slow, and yield limited results, in addition to requiring considerable physical effort and prior knowledge. There is also a lack of motivation among children and adults to recycle paper at home, due to the repetitive, tedious, and uncreative nature of manual methods. This results in a lack of direct connection between the waste generated and its potential for immediate reuse in the form of new objects. Today, industrial devices for paper recycling, such as shredders and pulpers, allow for the conversion of used paper into raw material. However, these devices are beyond the reach of home use due to their size, energy consumption, high price, and operational complexity. Other solutions, such as artisanal methods for making recycled paper manually, are impractical due to their slowness, inconsistent results, and lack of automation. They also do not allow for the creation of complex objects or offer an engaging or educational experience. 3D printing and injection molding machines exist for creating objects, but they are not designed to work with recycled paper nor are they part of a domestic circular process. Furthermore, they require specific commercial materials and technical expertise, thus deviating from the sustainability and accessibility goals of this invention. The present invention has its field of application in the sector of machines that promote sustainability, environmental education, domestic recycling and the manufacture of molded products by reusing waste. BACKGROUND OF THE INVENTION In the prior art, documents related to the proposed invention are known; however, none of them provide the advantageous characteristics of this invention nor effectively solve the drawbacks discussed previously. Thus, document ES 2390907 T3 proposes a waste paper recycling machine focused on producing new paper through a complex system of shredding, maceration, pulp concentration adjustment, and continuous manufacturing of recycled sheets. This machine, about the size of a piece of furniture, integrates multiple automated stages that allow for internal water circulation and pulp reuse, with specialized sections for each phase of the process. Its design aims to maintain the confidentiality of the paper's contents, making it suitable for offices, small businesses, or homes, although its primary focus is on the technical, continuous, and efficient production of recycled paper. In contrast, the proposed invention presents a more playful, educational, and accessible approach, focusing not on manufacturing recycled paper as sheets, but on reusing paper and cardboard waste to create molded objects such as toys or decorations. Its compact and modular design, low energy consumption, and semi-automatic operation facilitate home recycling without the need for an industrial facility or technical expertise. Unlike the previous document, this invention incorporates a creative and educational dimension, making it ideal for families and schools, promoting the circular economy from home and providing a tangible, immediate, and personalized recycling experience. On the other hand, document ES 2475164 T3 describes a compact waste paper recycling machine designed for integration into environments such as offices, small shops, or homes. This system includes a pulping section, which macerates and shreds the waste paper, and a papermaking section where the pulp is transformed into new recycled sheets. The machine incorporates a mesh belt conveyor to form wet paper from the pulp slurry and dry it by filtration. The entire process is contained within a closed circuit in the same unit, allowing for on-site use to maintain the confidentiality of the information printed on the original documents and ensure efficient and self-sufficient recycling. The proposed invention differs technically in that it is not geared towards the production of new sheets of paper, but rather towards the transformation of household paper and cardboard waste into molded objects, using a simplified system that combines shredding, pulping, pressing, and molding in a semi-automatic linear sequence. Unlike the previous device, which requires a papermaking system and complex suspension handling to produce sheets, the proposed invention dispenses with these mechanisms, significantly reducing technical complexity, the number of components, energy consumption, and maintenance requirements. This simplification makes it usable by anyone without technical expertise, allowing for an interactive and accessible recycling experience geared towards educational, recreational, or creative purposes, beyond the objective of document confidentiality pursued by the described device. Regarding document US 4,123,489 A, we find a system for processing waste paper, cardboard, and other similar materials, geared towards preparing them for industrial uses such as the production of pellets, mixtures, packaging, or animal feed. The process includes several stages: separation of unwanted materials, cutting using rotating cylinders with blades, screening with a trimming mesh to ensure a uniform material size (for example, down to 1 / 8 x 2 inches), and subsequent storage or direct feeding into pelletizing machines. This system is designed to handle large volumes of waste in formats such as bales, boxes, or industrial offcuts, using complementary machinery such as conveyors, fans, and sorting equipment, with an emphasis on increasing the density of the processed material to optimize its handling and transport. In comparison, the proposed invention presents a key technical difference in both scale and functionality. While the prior document focuses on the industrial treatment of waste for subsequent transformation into pellets or other bulk products, the proposed invention is designed for domestic or educational settings and enables, through a semi-automatic and integrated system, the transformation of paper and cardboard waste into molded objects with playful or practical value. It requires no industrial pre-processing or continuous material feeding, and instead of focusing on cutting and compacting the material for other processes, it combines shredding, pulping, molding, and drying functions in a single compact unit. This significantly reduces the necessary infrastructure and allows for immediate use of the recycled material, without relying on external processes or additional machinery. Thus we see that the means known to date in the state of the art do not provide an effective technical solution to the problems mentioned above. DESCRIPTION OF THE INVENTION Thus, the present invention is constituted from the following elements: A parallelepiped housing, electrically powered directly from the mains, equipped with at least one motor and at least one electronic circuit, featuring an emergency stop button, a safety cover on its top, and below it, an inlet opening with toothed rollers or stainless steel blades. Paper or cardboard is fed through this inlet opening, where the waste is shredded by the toothed rollers or stainless steel blades. Internally, below the inlet opening, the waste falls into a weighing compartment that contains at its base a scale divided in half, connected to an external display that reflects the weight of the waste that has fallen. This weighing compartment has an external lever that is operated to open the base scale in half, allowing the waste to fall into a pulping tank. The pulping tank features an inlet for water and other substances to be mixed with the waste by means of multiple cutting propellers. The base is slightly inclined towards one end, where a gate provides access to the pressing compartment below. This gate is opened by means of an external lever. These bars with curved-blade propellers can be activated electronically or manually. The pressing compartment has multiple microchannels at its base through which water flows to a drain. At one end of this base is a gate that can be opened by an external mechanism. The pressing compartment also has a horizontal plate, parallel to the base, that covers the entire area of ​​the pressing compartment and is operated by external handles. When the pulp generated from the waste is pressed with the horizontal plate, the liquids flow to the drain through the microchannels. The gate is then opened, allowing the now-dried pulp to fall into the mold-filling compartment.Alternatively, the compartment houses a push bar with a push surface provided with an actuating lever, said push bar being capable of moving from the end opposite the gate to the end where the gate is located, thus pushing all the contents of the compartment towards the gate. At the base of the mold-filling compartment are several hoppers through which the pulp falls onto molds for toys or other objects located in a storage bin with an access door. This bin has a heater that can be activated by an external button. Once the molds are ready, the door is opened and they are removed, thus completing the process from recycling paper or cardboard to creating a toy or similar object. The molds can continue to dry outside the machine. The invention features a control panel with a screen from which certain settings are managed, and also has a power button. The machine has a rear cover with access to the entire interior of the machine, as well as safety sensors, which prevent the machine from operating if any cover is open. These characteristics allow the proposed invention to provide a number of advantages, including the following: • Compact and safe design, ideal for home or educational environments. • Semi-automatic process that integrates crushing, pulping, molding and drying. • Low energy consumption. • Promote the circular economy from home. • Allows you to create personalized toys and objects with interchangeable molds. • Educational and recreational function, especially attractive to children. • Reduces manual effort compared to homemade methods. • It provides a creative and tangible experience of recycling. • It uses recyclable and sustainable materials in its manufacture. • It can be included in educational kits or environmental awareness programs. • It is an "all-in-one" type machine since it does both the recycling and the manufacturing of the object.

PREFERRED EMBODIMENT OF THE INVENTION A preferred embodiment of the proposed invention consists of the following elements: A parallelepiped housing (1) electrically powered directly from the mains, equipped with at least one motor (2) and at least one electronic circuit (3), which has an emergency stop button (4), while on its upper face there is a safety cover (5), and below it, an inlet opening (6) with toothed rollers or stainless steel blades. The paper or cardboard must be fed through this inlet opening, whereupon the waste is shredded by the action of the toothed rollers or stainless steel blades. Internally, below the inlet opening, the waste falls into a weighing compartment (7) which contains a scale (8) at its base, split in half and connected to an external display (9) that shows the weight of the waste. This weighing compartment has an external lever (10) that is operated to open the scale at the base in half, allowing the waste to fall into a pulping tank. The pulping tank (11) has an inlet for water (12) and other substances to be mixed with the waste by means of a plurality of cutting propellers (13), while the base is slightly inclined towards one of the ends where there is a gate (14) with access to the pressing compartment below, said gate being opened by means of an external lever (15). These bars with curved blade propellers can be activated electronically or manually. The pressing compartment (16) has a plurality of microchannels (17) at its base through which water flows to a drain, while at one end of this base is a gate (18) that can be opened by an external mechanism (19). The pressing compartment also has a horizontal plate (20), parallel to the base, which covers the entire area of ​​the pressing compartment and is operated by external handles (21). Thus, when the pulp generated from the waste is pressed with the horizontal plate, the liquids flow to the drain through the microchannels, and the gate is then opened, allowing the now dry pulp to fall into the mold filling compartment. At the base of the mold-filling compartment (22) are several hoppers (23) through which the pulp falls onto molds for toys or other objects located in a hopper (24) with an access door (25). This hopper has a heater (26) that can be activated by an external button. Once the molds are ready, the door is opened and they are removed, thus completing the process from recycling paper or cardboard to creating a toy or similar object. The molds can continue to dry outside the machine. The invention has a control panel via a screen (27) from which certain configurations are managed, while also having a power button (28). The machine has a rear cover with access to the entire interior of the machine, as well as safety sensors, which prevent the machine from operating if any cover is open.
