Description

Technical Field

[0001] The present invention relates to the technical field of waste recycling, and in particular to a punching waste recycling device. Background Art

[0002] In the modern textile industry, fabric punching, thanks to its unique processing effects, is widely used in a variety of fields, including clothing, home decor, and automotive interiors. For example, in clothing, punching can create stylish hollow patterns, enhancing the breathability and design of clothing. In home decor, perforated curtain fabrics are not only aesthetically pleasing but also provide light regulation. However, as the application of fabric punching continues to expand, the issue of waste recycling has gradually become a bottleneck hindering the efficient and environmentally friendly development of the industry.

[0003] Manual collection is a common method for recycling fabric punching waste. In small processing plants, workers must constantly clean up scattered waste next to the punching equipment, which is inefficient and extremely labor-intensive. The repetitive, long-term bending over to pick up waste easily leads to worker fatigue, increasing the likelihood of safety accidents. Furthermore, manual collection inevitably leaves waste unnoticed, and large amounts of waste debris flying into the processing environment, polluting the workplace and affecting workers' health.

[0004] Some companies use simple vacuuming devices for waste recycling, but such devices have many defects. The suction power of the vacuuming device is limited, and the vacuuming pipes are prone to clogging, resulting in unstable suction. When processing thicker and harder fabric waste, the vacuuming device is often unable to suck the waste away in time, causing the waste to accumulate in the punching area, which not only affects subsequent processing operations, but also generates static electricity due to friction between the waste and the fabric, adsorbing it on the surface of the fabric, thereby reducing product quality. In addition, simple vacuuming devices lack a centralized collection function, and waste is scattered in different dust collection areas. Cleaning still requires a lot of manpower, which makes it difficult to meet the needs of large-scale and automated production of modern fabric processing companies.

[0005] With consumers' ever-increasing demands for fabric quality and increasingly stringent environmental regulations, traditional waste recycling methods are no longer adapting to industry trends. Fabric processing companies urgently need an efficient and stable punching waste recycling device to achieve centralized and rapid waste recovery, safeguard product quality, and enhance competitiveness. Therefore, developing a high-performance punching waste recycling device has important practical significance and broad market prospects. Summary of the Invention

[0006] The purpose of the present invention is to provide a punching waste recycling device to solve the problems of low waste recycling efficiency and poor effect in the existing cloth punching processing process, to achieve efficient and centralized recycling of punching waste, and to improve the cleanliness of the processing environment and the quality of cloth products.

[0007] To achieve the above objectives, the present invention adopts the following technical means:

The punching assembly includes a punch rod, the bottom of the punch rod is connected to the punch through a punch clamp, the top of the punch rod is connected to a sealed rotary bearing, and the top of the punch rod is connected to the vacuum generator through a ventilation connector.

[0009] A further solution of the present invention is that the punch has a conical structure, and the through hole of the punch is arranged along the center line of the cone.

[0010] A further solution of the present invention is that the inner wall of the through hole of the punch is provided with a smooth coating.

[0011] A further solution of the present invention is that the punch is clamped with a punch clamp.

[0024] Punch 1, punch clamp 2, punch rod 3, sealed rotary bearing 4, vacuum generator 5, ventilation connection 6. DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1 As shown, a punching waste recycling device includes a punching assembly and a vacuum generator 5. The punching assembly includes a punch rod 3, the bottom of the punch rod 3 is connected to the punch 1 through a punch clamp 2, the top of the punch rod 3 is connected to a sealed rotary bearing 4, and the top of the punch rod 3 is connected to the vacuum generator 5 through a ventilation connector 6.

[0028] How it works

[0029] When the cloth punching processing equipment is started, the punching assembly starts working. Among them, the punch 1 connected to the punch clamp 2 at the bottom of the punch rod 3 moves up and down with the punch rod 3 under the drive of the equipment to perform a punching operation on the cloth.

[0030] When punch 1 punches the fabric, punching waste is generated. At this time, the vacuum generator 5 is activated synchronously and generates suction. Because the punch 1 is provided with a through hole, and this through hole forms a waste channel connected to the inside of the punch clamp 2 and the punch rod 3, the waste is sucked into the punch 1 through the through hole under the suction of the vacuum generator 5. The sucked waste passes through the punch clamp 2 and the punch rod 3 in sequence. The top of the punch rod 3 is connected to the vacuum generator 5 via the ventilation connector 6. The waste is finally transferred to the vacuum generator 5 for centralized collection.

[0031] During the entire working process, the sealed rotary bearing 4 is connected to the top of the punch rod 3, which ensures a good sealing effect when the punch rod 3 moves up and down, and at the same time allows the punch rod 3 to rotate within a certain range, avoiding the impact of friction and shaking during the movement of the punch rod on the waste recovery effect, and ensuring that the waste can be smoothly recycled through the waste channel.

[0032] Example 2

[0033] like Figure 1 As shown, a punching waste recycling device includes a punching assembly and a vacuum generator 5. The punching assembly includes a punch rod 3, the bottom of the punch rod 3 is connected to the punch 1 through a punch clamp 2, the top of the punch rod 3 is connected to a sealed rotary bearing 4, and the top of the punch rod 3 is connected to the vacuum generator 5 through a ventilation connector 6.

[0034] The punch 1 has a conical structure, and the through hole of the punch 1 is arranged along the center line of the cone.

[0035] The advantages of the above setup are:

[0036] Improve waste collection efficiency: When the conical punch 1 is punching cloth, waste is more likely to be concentrated on the top of the punch. Under the suction of the vacuum generator 5, the waste can enter the through hole more smoothly, reducing waste residue and scattering, thereby improving waste collection efficiency.

[0037] Reduce the risk of waste material clogging: The through hole is arranged along the tapered center line, so that after the waste material enters the punch 1, the transmission path is smoother, reducing the possibility of waste material getting stuck or blocked inside the punch, ensuring the smooth flow of the waste material recovery channel and maintaining the stable operation of the device.

[0038] Enhanced punching effect: During the punching process, the tapered punch 1 distributes force more evenly, can punch holes in the fabric more effectively, reduce punch wear, extend the service life of the punch, and improve the quality and accuracy of fabric punching.

[0039] Easy installation and maintenance: The unified conical structure design makes the installation and disassembly of the punch 1 more convenient. When replacing punches of different specifications, it can be quickly positioned and installed. During maintenance, it is easy to check and clean the waste residue inside the punch.

[0040] The inner wall of the through hole of the punch 1 is provided with a smooth coating.

[0041] The advantages of the above setup are:

[0042] Reduced risk of waste adhesion: The smooth coating effectively reduces the friction between the waste and the inner wall of the through-hole, preventing fiber waste from adhering to the hole wall during transmission, ensuring that the waste can pass through the punch 1 quickly, improving recycling efficiency.

[0043] Extended service life: The coating can prevent the sharp particles in the waste from scratching the inner wall of the punch, reducing wear and tear, especially when processing composite fabrics containing metal wire or hard fibers, significantly extending the service life of the punch 1.

[0044] Improved vacuum efficiency: The improved smoothness of the inner wall reduces airflow resistance, allowing the suction force generated by the vacuum generator 5 to act more effectively on the punching area, enhancing waste collection capabilities while reducing energy consumption.

[0045] Easy to clean and maintain: The smooth surface is not easy to retain dirt. When maintaining the equipment, the inside of the through hole can be cleaned quickly, reducing downtime and maintenance costs.

[0046] Avoiding secondary contamination: Reducing waste residue can prevent debris from mixing into finished fabrics during subsequent processing, improving product quality. This is especially suitable for medical textiles or precision electronic packaging materials that require high cleanliness.

[0047] The punch 1 is clamped with the punch clamp 2.

[0048] The advantages of the above setup are:

[0049] Quick Installation and Removal: The snap-on design eliminates the need for additional tools; simply plugging and unplugging the punch 1 and punch holder 2 allows for quick installation and removal, significantly reducing punch replacement time. During fabric processing, when punches of different sizes and shapes need to be replaced to meet diverse punching needs, quick switching allows for efficient production efficiency.

[0050] Accurate and reliable positioning: The design of the clamping structure enables the punch 1 to be accurately positioned in the punch clamp 2, ensuring the stable position of the punch during the punching process, avoiding punching deviation caused by installation error, thereby improving the accuracy and quality of fabric punching and ensuring product consistency.

[0051] Reduced maintenance costs: The simple clamping structure allows for separate inspection and repair of the punch 1 and punch holder 2 during equipment maintenance. If the punch becomes worn or damaged, it can be quickly replaced without replacing the entire connection, reducing maintenance costs and parts consumption.

[0052] Enhanced structural stability: The rationally designed clamping structure can provide sufficient connection strength, so that the punch 1 can still be firmly fixed on the punch clamp 2 when it is subjected to the impact force and vibration during the stamping process, ensuring the stable operation of the device under high-speed and high-frequency stamping working conditions, and reducing the risk of equipment failure caused by loose connections.

[0053] Improve production flexibility: The clamping method makes the replacement of the punch 1 more convenient. Enterprises can quickly replace the punch to produce different styles of fabric products according to different order requirements, which enhances production flexibility and responsiveness to market demand, helps enterprises expand their business scope and improve market competitiveness.

[0054] The punch clamp 2 and the punch rod 3 are connected by threaded connection, and a sealing gasket is provided at the connection.

[0055] The advantages of the above setup are:

[0056] Stable and reliable connection: The threaded connection provides a high-strength fastening force, which can ensure that the punch clamp 2 and the punch rod 3 maintain a firm connection during frequent up and down movements and vibrations, avoiding the punch position deviation caused by loosening, thereby ensuring punching accuracy and stability.

[0057] Excellent sealing performance: The setting of the sealing gasket effectively prevents waste and dust from leaking from the connection during the transmission process. This not only keeps the working environment clean, but also prevents waste from entering the interior of the equipment and causing damage to other components, thus extending the service life of the equipment.

[0058] Easy installation and removal: The threaded connection makes the installation and removal of the punch holder 2 and punch rod 3 simple and quick, without the need for complex tools. This is particularly convenient when performing equipment maintenance, replacing punches, or cleaning the punch holder, significantly reducing downtime.

[0059] Flexible and precise adjustment: Through the threaded connection, the relative position of the punch clamp 2 and the punch rod 3 can be accurately controlled to achieve fine adjustment of the punch height and angle to adapt to the requirements of different fabric materials and punching processes, thereby improving the applicability and processing flexibility of the equipment.

[0060] High reusability: The combined structure of threaded connections and sealing washers allows for multiple disassembly and reassembly without significantly reducing the reliability and sealing of the connection. This allows the equipment to maintain good working condition over long periods of use by simply replacing wearing parts such as sealing washers, reducing operating costs.

[0061] Adaptable to high-pressure environments: The suction generated by the vacuum generator 5 can create a negative pressure within the waste channel. The threaded connection and sealing gasket effectively resist this pressure differential, ensuring that waste does not leak during transport and maintaining the efficient operation of the entire recycling system.

[0062] Example 3

[0063] like Figure 1As shown, a punching waste recycling device includes a punching assembly and a vacuum generator 5. The punching assembly includes a punch rod 3, the bottom of the punch rod 3 is connected to the punch 1 through a punch clamp 2, the top of the punch rod 3 is connected to a sealed rotary bearing 4, and the top of the punch rod 3 is connected to the vacuum generator 5 through a ventilation connector 6.

[0064] The punch rod 3 is a hollow tubular structure.

[0065] The advantages of the above setup are:

[0066] Reduce weight: The hollow tubular structure is lighter than the solid structure, which helps to reduce the load of the entire stamping device. When the punch rod moves up and down, it can reduce the requirements for the drive mechanism and reduce energy consumption. At the same time, it can also improve the stability and flexibility of the equipment operation.

[0067] Optimize waste transmission: The hollow design provides a smooth transmission channel for waste. Cooperating with the through hole of punch 1 and other waste recovery components, the waste can be more efficiently transferred from the punching position to the waste collection device under the action of vacuum suction, avoiding blockage of waste during the transmission process and ensuring the normal operation of the waste recovery system.

[0068] Material Saving: The hollow tubular structure can reduce the amount of material used while meeting the punch strength and rigidity requirements, thereby reducing production costs. At the same time, it also reduces the overall weight of the equipment, making it easier to install, debug, and transport the equipment.

[0069] Easy installation and layout: The hollow tubular structure of the punch facilitates the layout and installation of various lines and pipelines. For example, the pipeline used to generate vacuum suction or the line connecting to the detection device can be arranged through the inside of the punch, making the external structure of the equipment more concise and reducing the clutter of external lines and pipelines. This facilitates equipment maintenance and management, and also improves the overall appearance of the equipment.

[0070] The sealed rotary bearing 4 is a deep groove ball sealed bearing.

[0071] The advantages of the above setup are:

[0072] Excellent rotational performance: Deep groove sealed ball bearings primarily support radial loads, but can also handle both radial and axial loads, and are capable of handling high rotational speeds. They provide smooth, low-friction rotational support during the rotational motion of the punch 3, ensuring that the punch 1 maintains its precise position and trajectory during the punching process, thereby improving punching accuracy and quality.

[0073] Reliable sealing: The bearing has a built-in sealing structure that can effectively prevent external dust, waste debris and grease from entering the bearing, avoiding contamination and wear of the bearing components. It also prevents internal grease leakage, ensuring good lubrication and normal operation of the bearing and extending the service life of the bearing.

[0074] Simple and compact structure: The deep groove ball sealed bearing has a simple structure, small size, and light weight. It can provide reliable support and rotation functions in a limited space, facilitates the connection and installation of the punch 3 with other components, and is conducive to the compact design and layout of the entire stamping equipment.

[0075] Low maintenance cost: Due to its simple structure, good sealing and long service life, frequent maintenance and servicing are not required during equipment operation, which reduces equipment maintenance costs and downtime and improves production efficiency.

[0076] Widely used: Deep groove sealed ball bearings are universal bearings with standardized sizes and specifications, making them readily available and relatively affordable. Their sophisticated design and manufacturing processes ensure product quality and reliability, meeting the operational requirements of most fabric punching equipment.

[0077] A filter is provided at the air intake of the vacuum generator 5 .

[0078] The advantages of the above setup are:

[0079] Protective equipment: The filter can intercept larger particles, fiber clusters and other impurities in the waste, preventing them from entering the vacuum generator, and preventing these impurities from causing wear, blockage or damage to key components such as the impeller and pump body of the vacuum generator, thereby extending the service life of the vacuum generator and ensuring its stable and efficient operation.

[0080] Improve waste collection efficiency: By filtering out some impurities that may affect the airflow, the airflow entering the vacuum generator is smoother, which helps maintain a stable vacuum degree, thereby improving the efficiency of waste collection, ensuring that waste can be sucked away in a timely and effective manner, and avoiding waste accumulation in the punching area, which affects the production process.

[0081] Reduced maintenance costs: Since the filter blocks most impurities, the cleaning and maintenance workload inside the vacuum generator is reduced. Frequent disassembly and cleaning of the vacuum generator is no longer necessary, reducing maintenance costs and downtime due to equipment maintenance, thereby improving production efficiency.

[0082] Ensure a clean working environment: Impurities intercepted on the filter will not be discharged into the surrounding environment with the airflow, which helps to keep the workplace clean and sanitary, improve the working environment, reduce the impact on the health of operators, and comply with relevant environmental protection requirements.

[0083] The ventilation connector 6 is a corrugated hose, and both ends of the ventilation connector 6 are respectively provided with quick connection joints.

[0084] The advantages of the above setup are:

[0085] Flexible connection: The corrugated hose has good flexibility and bendability, and can adapt to the relative position changes and vibrations between different components to a certain extent. It can effectively compensate for the displacement and deviation generated during the operation of the equipment and avoid component damage or loose connections caused by rigid connections.

[0086] Shock absorption and noise reduction: The corrugated structure of the corrugated hose can absorb part of the vibration energy, reduce the vibration and noise transmission generated during the operation of the equipment, help improve the working environment, reduce the impact on the health of operators, and also help to extend the service life of other parts of the equipment.

[0087] Corrosion and wear resistance: Usually corrugated hoses are made of corrosion-resistant and wear-resistant materials, which can adapt to different working environments, resist the erosion of waste materials, dust and other substances, as well as the wear that may be caused by airflow, thereby ensuring the sealing and service life of the ventilation connector.

[0088] Easy installation: The quick-connect connectors at both ends make it very convenient to connect and disassemble the corrugated hose with other components. There is no need to use complicated tools and tedious installation steps, which can greatly shorten the installation and maintenance time of the equipment and improve work efficiency.

[0089] Good sealing performance: Quick connect joints generally have a good sealing structure, which can ensure that there will be no air leakage at the connection part, ensure the sealing of the vacuum system, thereby maintaining the normal operation of the system and improving the efficiency of waste collection.

[0090] Strong scalability and versatility: The length and diameter of the corrugated hose are available in a variety of specifications, and the specifications of the quick-connect connectors are relatively standardized, which facilitates flexible configuration and expansion according to different equipment layouts and process requirements. It is also easy to connect and use with equipment components of other brands or models.

[0091] Example 4

[0092] A clothing fabric processing company needs to punch holes in thin cotton fabrics to create hollow patterns. The company uses the punching waste recycling device of the present invention, with the following parameters: the punch 1 is a tapered punch with an 8mm diameter and a 3mm through-hole diameter. The punch clamp 2 and the punch rod 3 are connected via an M8 thread, with a nitrile rubber sealing gasket at the connection. The punch rod 3 is a hollow tubular structure with a length of 200mm, an outer diameter of 12mm, and an inner diameter of 8mm. The sealed rotary bearing 4 is a 6001-2RS deep groove ball bearing. The vacuum generator 5 is an SMC ZX112A model. The ventilation connector 6 is a 300mm long polyurethane corrugated hose with quick-disconnect connectors installed at both ends.

[0093] During the production process, the device is installed on the stamping equipment and the vacuum generator 5 is started, generating a vacuum degree of -60kPa. When the punch 1 punches the cotton fabric, the resulting circular waste material is quickly sucked into the vacuum generator 5 through the punch 1 through-hole, the punch clamp 2, and the punch rod 3 under the action of vacuum suction. Due to the conical structure of the punch 1 and the smooth coating on the inner wall of the through-hole, the waste material is transported smoothly without clogging. After 8 hours of continuous production, the device operated stably, with a waste recovery efficiency of over 98%. The production environment remained clean and tidy, and the processed fabric showed no waste residue contamination, significantly improving the product qualification rate.

[0094] Example 5

[0095] A manufacturer of automotive interior fabrics needed to punch large ventilation holes in thick synthetic fiber fabrics. The device configuration for this scenario was as follows: Punch 1 was a 15mm-diameter tapered punch with a 5mm-diameter through-hole. Punch 1 and punch holder 2 were connected using a snap-on mechanism, facilitating quick replacement of punches of varying specifications. Punch rod 3 was 250mm long, with an outer diameter of 15mm and an inner diameter of 10mm. The sealed rotary bearing 4 used a 6203-2RS deep groove ball bearing. The vacuum generator 5 was a Festo VADMI-10 model. The ventilation connector 6 was a 400mm-long silicone corrugated hose with quick-connect connectors at both ends.

[0096] In actual production, the vacuum degree of the vacuum generator 5 is set to -70kPa. During the stamping process, the clamping method of the punch 1 and the punch clamp 2 reduces the punch replacement time from the original 10 minutes to 1 minute, greatly improving production efficiency. Due to the high hardness of synthetic fiber fabric waste, the adjustment bolt set on the punch clamp 2 can fine-tune the angle of the punch 1 to ensure the punching quality. The filter at the air intake effectively intercepts the fiber clumps in the waste and prevents the vacuum generator 5 from clogging. After testing, the device can complete the recycling of punching waste of 20 rolls of fabric per hour when processing thicker synthetic fiber fabrics. The equipment operates stably and the centralized collection of waste facilitates subsequent processing, saving the company a lot of manpower and cleaning costs.

Those skilled in the art will appreciate that other variations or modifications may be made based on the above description. It is not necessary and impossible to enumerate all embodiments here, and obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
