Description

Technical Field

[0001] The utility model relates to the technical field of fabric punching, in particular to a hole punching device for denim processing. Background Art

[0002] Fabric is a commonly used material in clothing, decoration and other items. Fabrics include various types such as chemical fiber carpets, non-woven wall coverings, linen, nylon, colored adhesive tapes, flannel, denim, etc. At present, some fabrics sometimes need to be punched during production and processing. Generally, punching operations are required on fabrics according to the usage and style requirements of the fabrics.

[0003] For example, the application number: CN202321543425.8. The utility model relates to the technical field of fabric punching, in particular to a textile fabric punching device, which includes a horizontal bottom plate, two conveying rollers respectively installed at both ends of the bottom plate, and a bracket fixed between the two conveying rollers. A supporting roller parallel to the conveying rollers and higher than their tops is fixedly installed inside the bracket. A fabric is movably connected between the bottom ends of the two conveying rollers and the top end of the supporting roller. A punching mechanism located directly above the supporting roller is arranged inside the bracket. The fabric is placed on the top of the supporting roller. First, it is pressed by the arc-shaped pressing plate in the punching mechanism and then punched by the tubular cutting knife. Since the top of the supporting roller is an arc-shaped curved surface structure, and the punching position is at the top ridge line of the supporting roller, compared with punching on a horizontal plane, it has a greater pressure, which helps to reduce the possibility of tearing at the edge of the fabric hole during punching, thereby improving the processing quality of the fabric. It solves the problem that the conventional punching method may increase the possibility of tearing at the hole edge.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that when the above equipment is applied, although it can solve the problem that the conventional punching method often spreads the fabric to be punched and the parts around the hole flat on the workbench, presses it by hands or a pressure mechanism and then uses a punching machine to punch. Such a punching method makes the horizontal contact area between the fabric and the tubular cutting knife larger. Therefore, under the same punching pressure, the pressure on the fabric surface is smaller compared to the case where the horizontal contact area is smaller. As a result, the possibility of tearing at the edge of the hole during fabric punching will increase, thereby reducing the overall quality of the fabric. However, during use, when the fabric is punched and processed by the punching device body, the air extractor sucks the shredded materials generated during punching into the supporting roller. However, the air extractor will suck the fabric into the input end of the air extractor, resulting in the phenomenon of blockage and necrosis of the air extractor, making the air extractor unable to suck the shredded materials into the supporting roller anymore.

When the fabric is punched and processed by the punching device body, the air extractor sucks the shredded materials generated during punching into the support roller. However, the air extractor will suck the fabric into the input end of the air extractor, resulting in the phenomenon of blockage and necrosis of the air extractor, making the air extractor unable to suck the shredded materials into the support roller anymore.

Both sides of the support roller are fixedly connected to the bottom of both sides of the inner wall of the bottom plate. The back of the air extractor is fixedly connected to the bottom of the front of the bottom plate. The input end of the air extractor passes through the front side of the inner wall of the bottom plate through a conduit and is connected to the inner wall of the support roller. A blocking plate is fixedly connected to the front surface of the inner wall of the support roller. Through holes are formed in the front of the blocking plate, and a plurality of through holes are formed and distributed at equal intervals in a ring shape.

[0008] Preferably, the anti-blocking assembly includes a motor. The back of the motor is fixedly connected to the front of the blocking plate. A cleaning rod is slidably connected to the back of the blocking plate. The output end of the motor passes through the back of the blocking plate and is fixedly connected to the front of the cleaning rod.

[0009] Preferably, a positioning frame is fixedly connected to the front side of the top of the bottom plate. The inner wall of the positioning frame is slidably connected to the bottom surface of the centralized box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting a baffle plate in the present utility model, when the denim is punched by the punching device body, the waste generated during punching will be sucked into the support roller by the air extractor. When the waste approaches the input end of the air extractor, while maintaining the suction air flow through the through holes, it does not prevent the blocking function of the baffle plate, avoiding the direct entry of waste into the input end of the air extractor. It solves the problem that when the fabric is punched by the punching device body, the air extractor sucks the shredded materials generated during punching into the support roller, but the air extractor will suck the fabric into the input end of the air extractor, resulting in the blockage and necrosis of the air extractor, making the air extractor unable to suck the waste into the support roller anymore, and achieves the effect of preventing the air extractor from being blocked.

[0015] 2. By setting a collection component in the present utility model, when the air extractor sucks the waste into the support roller, the waste is affected by the suction force and approaches the input end of the air extractor and is blocked by the baffle plate, the waste will flow into the centralized box through the connecting pipe for collection, preventing the excessive accumulation of waste in the support roller without being processed, which may cause the blockage inside the support roller and make the air extractor unable to collect the waste generated when the punching device body punches the denim anymore, thus achieving the effect that the waste in the support roller can be centrally processed.

[0016] 3. By setting an anti-blocking component in the present utility model, when the waste is sucked into the support roller by the air suction machine and is blocked by the baffle plate to prevent the waste from entering the input end of the air suction machine, the user starts the motor at the same time. Then, the output end of the motor drives the cleaning rod to rotate along the surface of the baffle plate, preventing the waste from adhering to the baffle plate due to the suction force of the air extractor, resulting in the blockage of the through holes, which causes the suction force at the output end of the air extractor unable to be transmitted to the entire inside of the support roller through the through holes, making the waste generated when the punching device body punches the fabric unable to be sucked into the support roller. Thus, the stability of the air extractor sucking the waste into the support roller is improved. Description of the Drawings

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 4 shown, a punching device for denim processing provided by the present utility model includes a bottom plate 1, a conveying roller 2, a punching device body 3, a support roller 4, and an air extractor 5. The two sides of the bottom of the conveying roller 2 are fixedly connected to the two sides of the top of the bottom plate 1. The two sides of the punching device body 3 are fixedly connected to the top of the two sides of the inner wall of the bottom plate 1. The two sides of the support roller 4 are fixedly connected to the bottom of the two sides of the inner wall of the bottom plate 1. The back of the air extractor 5 is fixedly connected to the bottom of the front of the bottom plate 1. The input end of the air extractor 5 passes through the bottom plate 1 through a conduit and is connected to the inner wall of the support roller 4. A baffle plate 6 is fixedly connected to the front surface of the inner wall of the support roller 4. A through hole 7 is opened on the front surface of the baffle plate 6. A plurality of through holes 7 are opened and are evenly distributed in a ring shape. A collection assembly 8 is fixedly connected to the front side of the bottom of the support roller 4. An anti-blocking assembly 9 is fixedly connected to the front surface of the baffle plate 6.

[0024] Referring to Figure 1 and Figure 2 , the collection assembly 8 includes a connecting pipe 801. The top of the connecting pipe 801 is fixedly connected to the front side of the bottom of the support roller 4. The bottom of the connecting pipe 801 is movably connected to a centralized box 802. The centralized box 802 is connected to the support roller 4 through the connecting pipe 801.

[0025] As a technical optimization solution of the present utility model, by providing a collection assembly 8, when the waste is sucked into the support roller 4 by the air extractor 5, and the waste approaches the input end of the air extractor 5 under the influence of the suction force and is blocked by the baffle 6, the waste will flow into the centralized box 802 through the connecting pipe 801 for collection, preventing the waste in the support roller 4 from accumulating too much and not being processed, thus causing blockage inside the support roller 4 and making the air extractor 5 unable to collect the waste generated during the punching process of the denim by the punching device body 3, thereby achieving the effect that the waste in the support roller 4 can be centrally processed.

[0026] Reference Figure 3 , the anti-blocking assembly 9 includes a motor 901, the back of the motor 901 is fixedly connected to the front of the baffle 6, and a cleaning rod 902 is slidably connected to the back of the baffle 6, and the output end of the motor 901 penetrates to the back of the baffle 6 and is fixedly connected to the front of the cleaning rod 902.

[0027] As a technical optimization solution of the present utility model, by providing the anti-blocking assembly 9, when the waste is sucked into the support roller 4 by the air suction machine and is blocked by the baffle 6 to prevent the waste from entering the input end of the air suction machine, the user starts the motor 901 at the same time. Subsequently, the output end of the motor 901 drives the cleaning rod 902 to rotate along the surface of the baffle 6, preventing the waste from adhering to the baffle 6 due to the suction force of the air extractor 5 and blocking the through hole 7, resulting in the suction force at the output end of the air extractor 5 being unable to be transmitted through the through hole 7 to the entire inside of the support roller 4, making the waste generated during the punching process of the punching device body 3 unable to be sucked into the support roller 4. Thus, the stability of the air extractor 5 in sucking the waste into the support roller 4 is improved.

[0028] Reference Figure 1 and Figure 2 , a positioning frame 10 is fixedly connected to the front side of the top of the bottom plate 1, and the inner wall of the positioning frame 10 is slidably connected to the bottom surface of the centralized box 802.

[0029] As a technical optimization solution of the present utility model, by providing the positioning frame 10, when it is necessary to align and connect the inner wall of the centralized box 802 with the inner wall of the connecting pipe 801 to prevent the suction force of the air extractor 5 from flowing out due to the gap in the docking of the centralized box 802 and the connecting pipe 801, the user aligns the bottom of the centralized box 802 with the inner wall of the positioning frame 10 and pushes it. Utilizing the movement trajectory provided by the inner wall of the positioning frame 10, the inner wall of the centralized box 802 is made to fit and connect with the inner wall of the connecting pipe 801, thereby achieving the effect that the inner walls can be accurately fitted and connected repeatedly when the centralized box 802 and the connecting pipe 801 are connected.

[0030] Reference Figure 2 and Figure 4, the bottom of the left side of the connecting pipe 801 is movably connected with a fixing block 11 through a pin, and the right side of the fixing block 11 is movably connected with the top of the left side of the centralized box 802.

[0031] As a technical optimization scheme of the present utility model, by setting the fixing block 11, after the user connects the centralized box 802 and the connecting pipe 801 by using the positioning frame 10, then rotates the fixing block 11 on the connecting pipe 801 to contact the centralized box 802, and then utilizes the cooperation between the fixing block 11 and the positioning frame 10, so that the four sides of the centralized box 802 are jointly limited and fixed, avoiding the influence on the centralized box 802 caused by the vibration generated when the drilling device body 3 works and the phenomenon of displacement, thus preventing the connection between the connecting pipe 801 and the inner wall of the centralized box 802 from having a gap, affecting the suction of the air extractor 5, and thereby improving the stability when the centralized box 802 is aligned and connected with the inner wall of the connecting pipe 801.

[0032] Reference Figure 4 , the bottom of the connecting pipe 801 is fixedly connected with a sealing gasket 12, and the bottom of the sealing gasket 12 is movably connected with the top of the centralized box 802.

[0033] As a technical optimization scheme of the present utility model, by setting the sealing gasket 12, when the user docks the centralized box 802 and the connecting pipe 801 by using the positioning frame 10, as the centralized box 802 moves, the sealing gasket 12 on the connecting pipe 801 is accordingly squeezed, so that after the centralized box 802 and the connecting pipe 801 are aligned and connected, due to the fact that the sealing gasket 12 is comprehensively squeezed and deformed, the contact surface at the docking part of the centralized box 802 and the connecting pipe 801 is increased, thereby reducing the gap existing on the contact surface, enhancing the sealing performance, and preventing the suction of the air extractor 5 from leaking through the gap.

[0034] Reference Figure 1 and Figure 2 , the bottom of the inner wall of the centralized box 802 is fixedly connected with a pressure sensor 13, the inner wall of the centralized box 802 is slidably connected with a force-bearing plate 14, the bottom of the force-bearing plate 14 is in contact with the top of the pressure sensor 13, the left side of the bottom plate 1 is fixedly connected with a control box 15, a buzzer 16 is arranged at the bottom of the control box 15, the right side of the buzzer 16 is fixedly connected with the left side of the bottom plate 1, and both the pressure sensor 13 and the buzzer 16 are electrically connected to the control box 15 through wires.

[0035] As a technical optimization solution of the present utility model, by setting a pressure sensor, a force-bearing plate 14, a control box 15 and a buzzer 16, when the waste material sucked by the air extractor 5 into the support roller 4 gradually falls into the centralized box 802, the force-bearing plate 14 is pressed down by the accumulation of the waste material. At the same time, the pressure sensor 13 monitors the weight of the accumulated waste material in real time and synchronously sends the monitoring data to the control box 15. When the monitoring data reaches the threshold value set in advance for the control box 15, the control box 15 sends a start signal to the buzzer 16, and then the buzzer 16 emits a prompt sound, reminding the user that the waste material accumulated in the centralized box 802 is too full and needs to be cleaned, thus achieving the effect of automatically reminding the user to clean when the waste material in the centralized box 802 accumulates too full.

[0036] The working principle and usage process of the present utility model: When in use, the user first passes the denim fabric under the conveying roller 2 on the left side of the bottom plate 1, then passes through the middle of the support roller 4 and the punching device body 3, and then passes the denim fabric under the conveying roller 2 on the right side of the bottom plate 1. Then, the punching device body 3, the air extractor 5 and the conveying roller 2 are started simultaneously, so that the denim fabric moves through the conveying roller 2 and is processed by punching through the punching device body 3. At the same time, the air inlet of the air extractor 5 sucks air into the support roller 4 and generates suction, sucking the waste material generated during punching into the support roller 4. Due to the influence of the suction of the air extractor 5, it approaches the air inlet of the air extractor 5. When approaching a certain position, the waste material is affected by the blocking plate 6 and stops advancing. Then, the waste material will flow into the centralized box 802 through the connecting pipe 801 for collection. At the same time, to avoid being blocked by the waste material attached to the blocking plate 6 due to the influence of the suction of the air extractor 5 on the through hole 7 and affecting the suction effect generated by the air inlet of the air extractor 5 through air extraction, the user starts the motor 901 to drive the cleaning rod 902 to rotate along the surface of the blocking plate 6, pushing the waste material attached to the surface of the blocking plate 6 into the connecting pipe 801, thus having the advantage of preventing the air extractor 5 from being blocked.

[0037] In summary: For this denim fabric processing punching device, by setting the blocking plate 6, after the denim fabric is processed by punching through the punching device body 3, the waste material generated during punching is sucked into the support roller 4 by the air extractor 5. Then, when the waste material approaches the air inlet of the air extractor 5, while using the through hole 7 to maintain the flow of the suction air, it does not prevent the blocking function of the blocking plate 6, avoiding the waste material directly entering the air inlet of the air extractor 5, and solving the problem that when the fabric is processed by punching through the punching device body, the air extractor sucks the shredded material generated during punching into the support roller, but the air extractor will suck the fabric into the air inlet of the air extractor, resulting in the phenomenon that the air extractor is blocked and necrotic, and the air extractor can no longer suck the waste material into the support roller.
