[0002] Denim is a cotton twill fabric with a unique style and wide range of uses. It is loved by the public for its wear resistance, durability, and versatility, and occupies an important position in both the fashion and industrial fields.

[0003] The exhaust system for denim laser processing equipment is a specialized ventilation and exhaust device designed to address pollutants (such as debris, dust, and harmful gases) generated during laser processing of denim. Its core function is to promptly remove waste generated during processing through airflow organization, ensuring a safe operating environment for the equipment and protecting the health of operators.

[0004] However, the components that collect debris are mostly enclosed structures, requiring the disassembly of multiple parts during cleaning. This process is complex and time-consuming, and debris is easily scattered during cleaning, causing secondary pollution of the work area. Frequent and complex cleaning and maintenance not only increase the labor intensity of workers but also reduce the efficiency of equipment use. Therefore, a ventilation device for denim laser processing equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an exhaust device for laser processing equipment of denim fabric, which aims to improve the problem that the cleaning process in the prior art is prone to causing debris to fly and secondary pollution of the work area.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A ventilation device for laser processing equipment of denim fabric includes a fixed frame a, a fixed frame b slidably connected to the inner wall of the top of the fixed frame a, a blower provided on the outer side wall of the fixed frame b, a blower head fixedly connected to the inner side wall of the fixed frame b, a collection box fixedly connected to the outer side wall of the fixed frame a, an opening and closing door hinged to the surface of the collection box, a suction fan provided on the outer side wall of the collection box, clamping components provided at the bottom of both the fixed frame a and the fixed frame b, and a cleaning component provided on the inner side wall of the collection box. The cleaning assembly includes a handle, a hinge rod hinged to the inner side wall of the handle, a push plate hinged to the end of the hinge rod away from the handle, and the push plate is elastically connected to the inner side wall of the collection box by a return spring.

[0007] Preferably, the clamping assembly includes a protrusion, the center of which has an internal threaded groove, the inner wall of which is threadedly connected to a threaded rod, the bottom end of the outer wall of the threaded rod is rotatably connected to a contact plate a, the surface of the contact plate a is fixedly connected to a guide rod, and the bottom ends of the inner sidewalls of both the fixing frame a and the fixing frame b are fixedly connected to a contact plate b.

[0008] Preferably, the rear end of the collection box has a groove, and the handle passes through and is slidably connected to the inner wall of the groove at the rear end of the collection box.

[0009] Preferably, one end of the reset spring is fixedly connected to the inner side wall of the collection box, and the other end of the reset spring is fixedly connected to the outer side wall of the push plate.

[0010] Preferably, the push plate is slidably connected to the inner sidewall of the collection box.

[0011] Preferably, the right side of the collection box has an empty slot, and the inner side wall of the fixing frame a has an empty slot, with the collection box corresponding to the empty slot of the fixing frame a.

[0012] Preferably, the protrusions are provided in two sets, one set of the protrusions is fixedly connected to the outer sidewall of the bottom end of the fixing frame a, and the other set of the protrusions is fixedly connected to the outer sidewall of the bottom end of the fixing frame b.

[0013] Preferably, the bottom ends of the fixing frame a and the fixing frame b are provided with sliding grooves, and the guide rod is slidably connected to the inner wall of the bottom end of the fixing frame a and the fixing frame b.

[0014] Compared with the prior art, the advantages of this utility model are: The denim laser processing equipment uses an exhaust system. A low-power blower blows debris from the fabric surface away from the processing area, preventing debris accumulation from affecting processing quality. A high-power suction fan quickly sucks the debris into the collection box after it is blown up, forming a "blowing and suction combined" debris removal mode. At the same time, the linkage design of the handle, hinge rod and push plate in the cleaning component allows the debris in the collection box to be easily pushed out by simply pulling the handle. With the help of the return spring, the cleaning process can be automatically reset. No tools are needed for the cleaning process, and the time is reduced to one-third of the traditional method, which greatly reduces the labor intensity of workers and improves the continuous working capacity of the equipment.

[0015] The sliding design of mounting brackets A and B allows the exhaust system to be quickly adjusted according to the width of the laser processing equipment, adapting to various equipment models and reducing the cost of repeated purchases when replacing equipment. The clamping assembly, through the cooperation of threaded rods and guide rods, enables rapid installation and stable fixation of the system, making the installation process simple and quick.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0025] Reference Figures 1-4 This utility model provides an exhaust device for laser processing equipment of denim fabric, including a fixed frame a1, a fixed frame b2 slidably connected to the inner wall of the top of the fixed frame a1, a blower 3 provided on the outer side wall of the fixed frame b2, and a blower head 4 fixedly connected to the inner side wall of the fixed frame b2. A collection box 5 is fixedly connected to the outer side wall of the fixed frame a1. An opening and closing door 7 is hinged to the surface of the collection box 5. A suction fan 6 is installed on the outer side wall of the collection box 5. Clamping components 8 are installed at the bottom of both the fixed frame a1 and the fixed frame b2. A cleaning component 9 is installed on the inner side wall of the collection box 5.

[0026] Specifically, both the fixing frame a1 and the fixing frame b2 are L-shaped, and the top of the fixing frame a1 is provided with a sliding groove that fits the top of the fixing frame b2, so that the fixing frame b2 can extend and slide on the inner wall of the top of the fixing frame a1, thereby adjusting according to the width of different laser processing equipment; the blower 3 is a low-power blower, which blows air outward from the blower head 4 to blow away the laser processing debris on the surface of the denim fabric.

[0027] Furthermore, a slot is provided on the right side of the collection box 5, and a slot is provided on the inner side wall of the fixing frame a1, with the collection box 5 corresponding to the slot of the fixing frame a1.

[0028] The above-mentioned collection box 5 corresponds to the slot of the fixed frame a1, so that when the suction fan 6 is working, it generates suction to suck the fabric debris into the collection box 5 through the slot of the fixed frame a1. At the same time, the suction fan 6 is a high-power suction fan, which is the existing technology.

[0029] In this preferred embodiment, refer to Figure 3 and Figure 4 The cleaning component 9 includes a handle 91, a hinge rod 92 is hinged to the inner side wall of the handle 91, and a push plate 93 is hinged to the end of the hinge rod 92 away from the handle 91. The push plate 93 is elastically connected to the inner side wall of the collection box 5 by a return spring 94.

[0030] Furthermore, a groove is provided at the rear end of the collection box 5, and the handle 91 passes through and is slidably connected to the inner wall of the groove at the rear end of the collection box 5.

[0031] The aforementioned cleaning component has a groove at the rear end of the collection box 5, which allows the handle 91 to move vertically up and down only in a straight line along the inner wall at the rear end of the collection box 5. When the handle 91 is pulled down, it pushes the push plate 93 through the hinge rod 92 to push the denim scraps collected inside the collection box 5 outwards, thus facilitating their centralized processing.

[0032] Furthermore, one end of the reset spring 94 is fixedly connected to the inner side wall of the collection box 5, and the other end of the reset spring 94 is fixedly connected to the outer side wall of the push plate 93; the push plate 93 is slidably connected to the inner side wall of the collection box 5.

[0033] The function of the aforementioned return spring 94 is to automatically reset the position of the push plate 93 after it has moved, and also to reset the position of the hinge rod 92 and the handle 91. The size of the push plate 93 matches the inner side of the collection box 5.

[0034] In this preferred embodiment, refer to Figure 2 and Figure 5The clamping assembly 8 includes a protrusion 81, an internal threaded groove at the center of the protrusion 81, a threaded rod 82 threadedly connected to the inner wall of the protrusion 81, a contact plate a83 rotatably connected to the bottom end of the outer wall of the threaded rod 82, a guide rod 84 fixedly connected to the surface of the contact plate a83, and a contact plate b85 fixedly connected to the bottom end of the inner side wall of the fixing frame a1 and the fixing frame b2.

[0035] Furthermore, two sets of protrusions 81 are provided. One set of protrusions 81 is fixedly connected to the outer sidewall of the bottom end of the fixing frame a1, and the other set of protrusions 81 is fixedly connected to the outer sidewall of the bottom end of the fixing frame b2. Specifically, when the protrusions 81 rotate, they will drive the contact plate a83 to move up and down synchronously, thereby making contact with the contact plate b85, thus fixing the whole assembly to the surface of the laser processing equipment.

[0036] Furthermore, the bottom ends of the fixed frame a1 and fixed frame b2 are provided with sliding grooves, and the guide rod 84 is slidably connected to the inner wall of the bottom end of the fixed frame a1 and fixed frame b2. By providing the guide rod 84, the vertical movement of the contact plate a83 can be guided, so that it can only move vertically in a straight line.

[0037] The basic working principle of this utility model is as follows: The blower 3 installed on the outer side wall of the fixed frame b2 is a low-power blower. When it is working, the air force generated by it is blown outward through the blower head 4 on the inner side wall of the fixed frame b2. When laser processing of denim fabric produces debris, the air blown out by the blower head 4 blows the debris away from the processing area, preventing the debris from accumulating and affecting the processing quality or damaging the laser equipment. The collection box 5 is fixedly connected to the outer side wall of the fixed frame a1. The right side of the collection box 5 and the inner side wall of the fixed frame a1 both have corresponding slots. The suction fan 6 on the outside of the collection box 5 is a high-power suction fan. When it is working, it generates strong suction. After the blower 3 blows up the debris, the suction fan 6 sucks the debris into the collection box 5 through the slot of the fixed frame a1, realizing the effective collection of debris. The hinged door 7 on the surface of the collection box 5 makes it easy to open it regularly for internal cleaning and maintenance.

[0038] The cleaning component 9 is used to conveniently clean up the debris accumulated inside the collection box 5. The handle 91 passes through and is slidably connected to the inner wall of the rear slide groove of the collection box 5. It can only move up and down in a straight line on the inner wall of the rear end of the collection box 5. When the handle 91 is pulled down, the handle 91 pushes the push plate 93 to slide on the inner side wall of the collection box 5 through the hinge rod 92. The size of the push plate 93 matches the inner side of the collection box 5, which can push the denim fabric debris inside the collection box 5 outwards simultaneously for centralized processing. The push plate 93 is elastically connected to the inner side wall of the collection box 5 through the return spring 94. One end of the return spring 94 is fixed to the inner side of the collection box 5, and the other end is fixed to the outer side of the push plate 93. When the handle 91 is released, the return spring 94 releases its elastic potential energy, pushing the push plate 93 to move in the opposite direction. At the same time, the handle 91 is reset through the hinge rod 92, preparing for the next cleaning.

[0039] Two sets of protrusions 81 are fixed to the outer sidewalls of the bottom ends of the fixed frame a1 and fixed frame b2, respectively. An internal thread groove is opened at the center of each protrusion and threadedly connected to the threaded rod 82. When the threaded rod 82 is rotated, the guide rod 84 is slidably connected in the groove at the bottom end of the fixed frame a1 and fixed frame b2. The guide rod 84 restricts the movement of the contact plate a83, so that it can only move up and down in a straight line. This causes the contact plate a83 to move up and down synchronously with the threaded rod 82. When the contact plate a83 moves down and fits against the contact plate b85 at the bottom end of the inner sidewall of the fixed frame a1 and fixed frame b2, the whole can be firmly fixed to the surface of the laser processing equipment. By rotating the threaded rod 82, the clamping force can be easily adjusted to ensure that the exhaust system is stable and reliable during operation and will not be displaced due to vibration or external force.
