Description

Technical Field

[0001] The utility model relates to the technical field of dustproof clothing processing, in particular to a laser cutting machine with a pressing roller. Background Art

[0002] In modern manufacturing, laser cutting technology has been widely used due to its significant advantages such as high precision, high speed, and non-contact processing. When processing dust-free clothing fabrics, laser cutting machines are needed to cut the fabrics. With the rapid development of science and technology, the electronics, semiconductor, and pharmaceutical industries have increasingly stringent requirements for the cleanliness of the production environment. Dust-free workshops are key production sites in these industries, and the dust-free clothing worn by the staff plays a vital role. Laser cutting technology can accurately cut fabrics with extremely small heat-affected areas, greatly improving the quality and performance of dust-free clothing and effectively ensuring the clean production environment of dust-free workshops.

[0003] Among them, the "laser cutting machine with material collecting function" disclosed in the publication number "CN220993157U" has solved many technical disadvantages of the device, that is, when collecting the cut workpiece, the workpiece is transported by a conveyor belt, but the workpiece cannot be fixed during the cutting process, resulting in poor cutting effect.

[0004] However, there are still many defects in the actual use of laser cutting machines with similar structures. For example, the device in the existing technology has a reduced laser cutting accuracy due to uneven fabric thickness, and the cutting edge is uneven. The traditional fixed pressing device cannot flexibly cope with fabrics of different thicknesses and requires manual intervention and adjustment, which affects production efficiency and cutting quality. Therefore, there is an urgent need to develop a laser cutting machine with a pressing roller to solve these practical problems. Utility Model Content

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a laser cutting machine with a nip roller, comprising a box body and further comprising:

[0007] The mounting frame is set on the top of the box for load support;

[0008] The driving mechanism is arranged on the top of the mounting frame and is used to cut the cleanroom clothing fabric;

[0015] Preferably, the static electricity removal mechanism includes a mounting base, a plasma wind rod is fixedly mounted on the top of the mounting base, and a delivery pipe extending to the inside of the mounting base is equidistantly mounted on the bottom of the plasma wind rod, an air pump is fixedly mounted on one side of the plasma wind rod through a pipe, a filter box is fixedly mounted on one side of the air pump through a pipe, and a plasma generator electrically connected to the plasma wind rod is fixedly mounted on the top side of the front of the box.

[0016] Preferably, the conveying assembly includes a fixing frame, a constant speed motor is fixedly mounted on one side of the fixing frame, and a conveying roller for performing friction conveying on the cleanroom clothing fabric is fixedly mounted on the output end of the constant speed motor.

[0017] Preferably, a limit plate is fixedly installed on the top of the box body, and a mounting groove for the output end transmission of the uniform speed motor is opened inside the limit plate.

[0018] The utility model provides a laser cutting machine with a press roller. Compared with the prior art, it has the following advantages:

[0019] 1. With the strong elastic force of the resistance spring, the support rod can be pushed to drive the shaft frame to move downward, so that the resistance roller can tightly resist the clean-room clothing fabric. When working in conjunction with the driving mechanism, the resistance roller can be driven to resist and move the clean-room clothing fabric. Due to the elastic adjustability of the resistance spring, the resistance roller can adapt to fabrics of different thicknesses and accurately resist and press them. At the same time, the moving driving mechanism can drive the laser head to cut the fabric. Through the two sets of resistance rollers located at the fabric cutting position and performing resistance and pressing, the laser head cooperates with each other to achieve the function of improving the cutting accuracy of the laser head, ensuring that the cutting edge is neat and smooth, reducing the burrs and defects after the fabric is cut, and improving the quality and appearance of the clean-room clothing finished product. It can adapt to fabrics of different thicknesses, enhance the compatibility and flexibility of the equipment for processing clean-room clothing fabrics of various specifications, eliminate the need to frequently adjust equipment parameters, improve production efficiency, solve the problem of reduced laser cutting accuracy and uneven cutting edges due to uneven fabric thickness, and overcome the problem that traditional fixed pressing devices cannot flexibly cope with fabrics of different thicknesses and require manual intervention and adjustment, affecting production efficiency and cutting quality.

[0020] 2. The air pump is started, and the external air is drawn by the air pump and first enters the filter box for filtration to remove impurities, dust, etc. in the air to obtain dust-free air. The filtered air is transported to the plasma wind rod through the pipe. At the same time, the plasma generator is energized to provide high voltage electricity for the plasma wind rod, so that the gas in the plasma wind rod is ionized to form plasma. When the cleanroom cloth inside the mounting seat passes under the plasma wind rod, the plasma interacts with the cloth surface to neutralize the static charge on the cloth, thereby realizing the static removal function of the cleanroom cloth, avoiding the problem of subsequent secondary dust removal of the cleanroom cloth caused by the cleanroom cloth easily absorbing dust, reducing the process of using the device to process the cleanroom cloth, and being able to stably produce high-quality, high-cleanliness cleanroom products that meet strict electrostatic standards, thereby improving the competitiveness of the products in the market, meeting the demand for cleanroom clothes in industries with high requirements for dust-free environment such as electronics, pharmaceuticals, and medical care, and at the same time bringing good economic and social benefits to the enterprise.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 4 , this utility model provides two technical solutions:

[0028] First embodiment: A laser cutting machine with a nip roller, comprising a housing 1, and further comprising:

[0029] The mounting frame is provided on the top of the box 1 for load support;

[0030] The drive mechanism 2 is arranged on the top of the mounting frame and is used to cut the cleanroom fabric. The drive mechanism 2 includes a servo motor 201 arranged on one side of the mounting frame. A lead screw 202 is fixedly mounted on the output end of the servo motor 201. A screw sleeve 203 is threadedly mounted on the outer side of the lead screw 202. A laser head 204 for cutting the cleanroom fabric is fixedly mounted on the bottom of the screw sleeve 203.

[0031] The holding mechanism 3 is provided on one side of the driving mechanism 2 and is used to hold and limit the cleanroom cloth to be cut. The holding mechanism 3 includes two sets of shells 301. The shells 301 are fixedly provided with elastically deformable resistance springs 302. The bottom end of the resistance springs 302 is fixedly provided with a support rod 303 extending from the inside of the shell 301. The bottom end of the support rod 303 is fixedly provided with a shaft frame 304. The shaft frame 304 has a resistance roller 305 rotatably provided inside the shaft frame 304 for resisting and holding the cleanroom cloth.

[0032] The static electricity removal mechanism 4 is provided on one side of the box 1 and is used to remove static electricity from the cleanroom clothing fabric;

[0033] The conveying assembly is arranged outside the mounting frame and is used to convey the cleanroom clothing fabric. The conveying assembly includes a fixing frame 5, a constant speed motor 501 is fixedly mounted on one side of the fixing frame 5, and a conveying roller 502 for resisting and conveying the cleanroom clothing fabric is fixedly mounted on the output end of the constant speed motor 501;

[0034] A controller 101 is fixedly mounted on the front side of the box 1, and a display screen is fixedly mounted on the front side of the controller 101. A limit plate 6 is fixedly mounted on the top of the box 1, and a mounting slot for the output end transmission of the uniform speed motor 501 is opened inside the limit plate 6.

[0035] At the beginning of the work, the cleanroom fabric to be processed is placed in the area defined by the limit plate 6. At this time, the constant speed motor 501 is powered on, driving the conveying roller 502 to start rotating. The rotating conveying roller 502 contacts the fabric and generates a resistance force, thereby stably and efficiently conveying the cleanroom fabric within the limit plate 6, smoothly realizing the automatic conveying function of the fabric. At the same time, the rational design of the mounting slot avoids unnecessary restrictions when the constant speed motor 501 drives the conveying roller 502 to rotate.

[0036] As the fabric is conveyed, the strong elastic force of the resistance spring 302 pushes the support rod 303 and the shaft frame 304 downward, causing the resistance roller 305 to tightly contact the conveyed cleanroom fabric. When the driving mechanism 2 starts to operate, it can drive the resistance roller 305 to resist the fabric. Due to the elasticity and adjustability of the resistance spring 302, the resistance roller 305 can adapt to fabrics of different thicknesses and accurately resist and hold them.

[0037] At the same time, the servo motor 201 is powered on and drives the lead screw 202 to rotate. The rotating lead screw 202 drives the screw sleeve 203 to move horizontally, which in turn drives the laser head 204 to move synchronously, accurately adjusting the cutting position of the laser head 204 on the fabric, preparing for the subsequent laser cutting operation. Afterwards, the moving drive mechanism 2 drives the laser head 204 to cut the fabric. With the close cooperation of the two sets of contact rollers 305 located at the fabric cutting position and performing contact and pressure holding with the laser head 204, the cutting accuracy of the laser head 204 is improved, ensuring a neat and smooth cut edge, reducing burrs and defects in the fabric after cutting, improving the quality and aesthetics of the finished cleanroom clothing, and being able to adapt to fabrics of different thicknesses, enhancing the compatibility and flexibility of the equipment for processing cleanroom clothing fabrics of various specifications.

[0038] The second embodiment differs from the first embodiment mainly in that: the static electricity removal mechanism 4 includes a mounting base 401, a plasma wind rod 402 is fixedly mounted on the top of the mounting base 401, and a delivery pipe extending into the interior of the mounting base 401 is equidistantly mounted on the bottom of the plasma wind rod 402, an air pump 403 is fixedly mounted on one side of the plasma wind rod 402 through a pipe, a filter box 404 is fixedly mounted on one side of the air pump 403 through a pipe, and a plasma generator 405 electrically connected to the plasma wind rod 402 is fixedly mounted on one side of the top of the front of the box body 1;

[0039] During operation, the air pump 403 starts first, forcefully extracting external air and directing it into the filter box 404. With its efficient filtration system, it accurately removes all kinds of impurities and dust in the air, thereby obtaining a pure and dust-free air source. The purified air is smoothly and stably transmitted to the plasma wind wand 402 through the pipe. At the same time, the plasma generator 405 is powered on and operates synchronously, releasing high voltage electricity to energize the plasma wind wand 402, prompting the gas inside it to quickly ionize and successfully form plasma.

[0040] When the cleanroom clothing fabric inside the mounting base 401 is transferred to the area below the plasma wind wand 402, the active plasma interacts closely and efficiently with the surface of the fabric, accurately neutralizing the static charge carried by the fabric, and effectively achieving the core function of removing static electricity from the cleanroom clothing fabric. This innovative design effectively avoids the subsequent complicated secondary dust removal process derived from electrostatic adsorption of dust, significantly reducing the overall process complexity and cost investment of the device in processing cleanroom clothing fabrics. Based on this excellent performance, it is possible to continuously and stably produce high-quality, ultra-clean, and high-quality cleanroom clothing products that fully comply with strict electrostatic standards and specifications.

[0041] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.
