A fiberglass cloth cutting device

Abstract

This utility model relates to the technical field of fiberglass cloth processing equipment, and discloses a fiberglass cloth cutting device. The fiberglass cloth cutting device includes a workbench, the interior of which is equipped with a dust collection mechanism. This fiberglass cloth cutting device, by incorporating the dust collection mechanism and a dust cover, can form a relatively enclosed operating space, effectively covering the cutting area. The conical design of the dust collection trough, combined with a fixed collection cylinder above it, efficiently guides and concentrates the dust and fiber debris generated during cutting. An inclined baffle further assists in the dust settling to the bottom of the collection cylinder, preventing it from being directly carried into the ventilation duct by the airflow. An exhaust fan generates negative pressure airflow through a connecting pipe and the ventilation duct, drawing dust-laden air from the exhaust port at the top of the dust cover. After larger debris is intercepted by a filter plate, clean air is discharged through the exhaust pipe, while the dust is collected in a sliding drawer at the bottom.

Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass cloth processing equipment, specifically to a fiberglass cloth cutting device. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages include good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, its disadvantages include brittleness and poor wear resistance. It is made from six minerals, namely pyrophyllite, quartz sand, limestone, dolomite, borocalcite, and boromagnesia, through high-temperature melting, drawing, winding, and weaving processes. The diameter of its single filaments ranges from a few micrometers to over twenty micrometers, and each bundle of fiber consists of hundreds or even thousands of single filaments. Glass fiber is commonly used as a reinforcing material in composite materials, an electrical insulation material, a thermal insulation material, and circuit boards in various sectors of the national economy.

[0003] According to a fiberglass cloth cutting device disclosed in the above application (Announcement No.: CN217203327U), the fiberglass cloth is easily conveyed to the lower end of the cutting blade by the cloth conveying mechanism, and the cloth is easily cut by the fixed plate, hydraulic telescopic rod, guide rail and cutting blade. The cloth is easily cut by the slide groove, pressure plate and second spring.

[0004] However, in actual use, the glass fiber debris of the above-mentioned equipment is extremely harmful to the human body. The equipment only collects the glass fiber debris generated during cutting by gravity. During the cutting process, a large amount of glass fiber debris floats, but the equipment does not have an active dust extraction mechanism to prevent the glass fiber debris from injuring the human body. In view of this, we propose a fiberglass cloth cutting device. Utility Model Content

[0005] The purpose of this invention is to provide a fiberglass cloth cutting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fiberglass cloth cutting device includes a workbench, and a dust collection mechanism is provided inside the workbench. The dust collection mechanism includes:

[0007] A dust cover, the bottom surface of which is hinged to the upper surface of the workbench, an exhaust vent on the top surface of which is provided, a dust collection trough on the upper surface of which is provided, a collection cylinder fixedly connected through the upper surface of which is provided, and a ventilation slot on the side of the collection cylinder away from the end of the workbench.

[0008] A baffle is fixedly connected to the inner side wall of the collection cylinder. One end of the ventilation slot away from the baffle is fixedly connected to one end of a connecting pipe. The other end of the connecting pipe is fixedly connected to the input end of an exhaust fan. The output end of the exhaust fan is fixedly connected to an exhaust pipe. A drawer is slidably connected to the bottom surface of the collection cylinder.

[0009] Preferably, the dust collection trough is cone-shaped, and the top surface of the collection cylinder is in contact with the top surface of the dust collection trough. The inner wall of the exhaust port is fixedly connected to the inner wall of the ventilation trough with a filter plate.

[0010] Preferably, the baffle is positioned above the ventilation slot and is inclined. A handle is fixedly connected to the side wall of the dust cover, and a silicone pad is fixedly connected to the surface of the dust cover. An observation window is provided at the end of the dust cover near the handle.

[0011] Preferably, the dust cover is provided with a sealing mechanism at its end. The sealing mechanism includes a through groove, which is opened at the end of the dust cover. A fixed shaft is fixedly connected to the side wall of the through groove. One end of a spiral spring is fixedly connected to the outer surface of the fixed shaft. The other end of the spiral spring is fixedly connected to the inner wall of the connecting cylinder. A sealing plate is fixedly connected to the outer wall of the connecting cylinder.

[0012] Preferably, the number of sealing plates is provided in multiple sets, and every two sets of sealing plates are distributed in a mirror-symmetrical manner on the side wall of the through groove, and a magnet is provided between adjacent sets of sealing plates.

[0013] Preferably, the upper surface of the workbench is fixedly connected with a clamping component and a cutting component, and the number of clamping components is set to two sets, which are distributed in a mirror-symmetrical manner on the upper surface of the workbench.

[0014] Preferably, the drawer is positioned directly below the multiple sets of collection tubes, and the side wall of the drawer is slidably connected to the inner side wall of the workbench.

[0015] Compared with the prior art, the present invention provides a fiberglass cloth cutting device, which has the following beneficial effects:

[0016] 1. This fiberglass cloth cutting equipment, equipped with a dust collection mechanism and a dust cover, can form a relatively enclosed operating space, effectively covering the cutting area. The conical design of the dust collection trough, combined with the fixed collection cylinder above it, can efficiently guide and concentrate the dust and fiber debris generated during cutting. The inclined baffle further assists the dust to settle to the bottom of the collection cylinder, preventing it from being directly carried into the ventilation duct by the airflow. The exhaust fan generates negative pressure airflow through the connecting pipe and the ventilation duct, drawing in dusty air from the exhaust port at the top of the dust cover. After the filter plate intercepts larger debris, the clean air is discharged through the exhaust pipe, while the dust is collected in the sliding drawer at the bottom.

[0017] 2. This fiberglass cloth cutting equipment is equipped with a sealing mechanism. With the torque of the spiral spring, multiple sealing plates on the connecting cylinder have an automatic closing tendency. When the cloth is pushed into or pulled out of the through groove, the sealing plate is pushed open. Once the cloth stops moving or moves away, the sealing plate quickly springs back to the closed state under the restoring force of the spiral spring. The magnets set between adjacent sealing plates further enhance the tightness of the closure. Attached Figure Description

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a fiberglass cloth cutting device, including a workbench 1, and a dust collection mechanism 2 is provided inside the workbench 1. The dust collection mechanism 2 includes: a dust cover 21, an exhaust port 22, a dust collection trough 23, a collection cylinder 24, a ventilation trough 25, a baffle 26, a connecting pipe 27, an exhaust fan 28, an exhaust pipe 29, and a drawer 210.

[0025] In one embodiment of this utility model, the bottom surface of the dust cover 21 is hinged to the upper surface of the workbench 1. The size of the dust cover 21 can cover the entire dust collection trough 23, so that a relatively closed space can be formed between the dust cover 21 and the workbench 1, which can effectively prevent the glass fiber debris generated during cutting from flying around and causing physical injury to the workers. The top surface of the dust cover 21 is provided with an exhaust vent 22, which is designed to draw outside air into the interior of the dust cover 21. While uniformly collecting the glass fiber debris, it can also provide a certain degree of heat dissipation for the cutting component 5. The upper surface of the workbench 1 is provided with a dust collection trough 23, which can naturally receive the glass fibers falling due to the suction mechanism 2 and natural gravity. A collection cylinder 24 is fixedly connected to the upper surface of the dust collection trough 23. A ventilation slot 25 is provided on the side of the collection cylinder 24 away from the workbench 1. The side wall of the baffle 26 is fixedly connected to the inner side wall of the collection cylinder 24. Glass fiber debris falling onto the upper surface of the dust collection trough 23 will enter the interior of the collection cylinder 24 with the airflow, effectively guiding the glass fiber debris. The inclined baffle 26 further guides the glass fiber debris, further assisting in its deposition. A connecting pipe 27 is fixedly connected to the end of the ventilation slot 25 away from the baffle 26. The other end of the connecting pipe 27 is fixedly connected to the input end of an exhaust fan 28. An exhaust pipe 29 is fixedly connected to the output end of the exhaust fan 28. The collection cylinder 24... A drawer 210 is slidably connected to the bottom surface. Outside air is discharged to the outside of the equipment through the connecting pipe 27, the exhaust fan 28, and the exhaust pipe 29, completing air circulation. The dust collection trough 23 is cone-shaped. The cone shape of the dust collection trough 23 is more conducive to the collection of glass fiber debris under neutral influence. The top surface of the collection cylinder 24 is in contact with the top surface of the dust collection trough 23. The top surface of the collection cylinder 24 is in contact with the upper surface of the cone-shaped dust collection trough 23, which can prevent the initially deposited glass fiber debris from scattering and is more conducive to collecting the initially collected glass fiber debris. The inner wall of the exhaust port 22 and the inner wall of the ventilation slot 25 are fixedly connected to a filter plate. The filter plate set in the exhaust port 22 can effectively block external impurities from entering the interior of the dust cover 21, preventing external... Impurities affect the fiberglass cloth. Meanwhile, the filter plate installed on the inner wall of the ventilation slot 25 prevents fiberglass debris from entering the connecting pipe 27 and from being discharged from the equipment by the exhaust fan 28. A baffle 26 is positioned above the ventilation slot 25 and is inclined, which better guides the fiberglass debris in the collection cylinder 24 and further directs it into the drawer 210. A handle is fixedly connected to the side wall of the dust cover 21, and a silicone pad is fixedly connected to the bottom surface of the dust cover 21. An observation window is provided at the end of the dust cover 21 near the handle, allowing staff to easily perform real-time maintenance on the equipment.This design facilitates equipment maintenance and repair, and the inclusion of silicone dots further enhances the seal between the dust cover 21 and the workbench 1. Operators can also observe the equipment's operation through the viewing window.

[0026] In addition, a sealing mechanism 3 is provided at the end of the dust cover 21. The sealing mechanism 3 includes a through groove 31, which is located at the end of the dust cover 21. The through groove 31 can be used as an inlet and outlet. A fixed shaft 32 is fixedly connected to the side wall of the through groove 31. One end of a spiral spring 33 is fixedly connected to the outer surface of the fixed shaft 32. The other end of the spiral spring 33 is fixedly connected to the inner wall of the connecting cylinder 34. A sealing plate 35 is fixedly connected to the outer wall of the connecting cylinder 34. When the fiberglass cloth passes through, it pushes the sealing plate 35, causing the connecting cylinder 34 and the spiral spring 33 to rotate around the fixed shaft 31. 2. The spiral spring 33 rotates and accumulates elasticity. When the fiberglass cloth stops or moves away, the spiral spring 33 releases the accumulated elasticity, driving the connecting cylinder 34 to rotate, which further closes the sealing plate 35. There are multiple sets of sealing plates 35, and every two sets of sealing plates 35 are distributed in a mirror symmetrical manner on the side wall of the through groove 31. A magnet is provided between two adjacent sets of sealing plates 35. By providing a magnet between two adjacent sets of sealing plates 35, the suction force of the exhaust fan 28 can be prevented from opening the sealing plate 35, and the magnet further increases the tightness of the closure between the sealing plates 35.

[0027] In this embodiment of the invention, a clamping assembly 4 and a cutting assembly 5 are fixedly connected to the upper surface of the workbench 1. Two sets of clamping assemblies 4 are provided, and the two sets of clamping assemblies 4 are distributed in a mirror-symmetrical manner on the upper surface of the workbench 1. The clamping assemblies 4 can effectively clamp the fiberglass cloth, preventing the fiberglass cloth from moving during the cutting process and causing unsatisfactory cutting results. The clamping assemblies 4 are fixed by rollers, which can meet the controllable displacement of the fiberglass cloth in the equipment. The drawer 210 is located directly below the multiple sets of collection cylinders 24, and the side wall of the drawer 210 is slidably connected to the inner side wall of the workbench 1. The fiberglass debris collected by the collection cylinders 24 will fall into the interior of the drawer 210 under the action of gravity. The fiberglass debris can be uniformly processed by pulling out the drawer 210.

[0028] In this utility model, during operation, the fiberglass cloth is first placed in the clamping assembly 4 through the sealing mechanism 3. The cloth is fixed by two sets of clamping assemblies 4. At the same time, the cutting assembly 5 is started to cut the cloth, and the exhaust fan 28 is turned on. Fiberglass debris is sucked in through the exhaust port 22 on the top of the dust cover 21 under negative pressure. The fiberglass debris is squeezed off the dust collection trough 23 and falls into the collection cylinder 24. Then, the inclined baffle 26 above the ventilation trough 25 guides the dust to fall into the drawer 210 below. The drawer 210 can be pulled out by the staff to uniformly process the fiberglass debris. The filter plate blocks the fiber from being sucked into the fan, and the purified air is discharged through the exhaust pipe 29.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
