Description

Technical Field

[0001] This utility model relates to the technical field of fabric cutting devices, specifically to a cutting device for environmentally friendly flame-retardant fabric. Background Technology

[0002] Environmentally friendly flame-retardant fabrics are textiles that combine flame-retardant properties with environmental characteristics through special processes or material modification. They are widely used in protective, home furnishing, and industrial fields. In the home furnishing field, environmentally friendly flame-retardant fabrics are most commonly used as sofa fabrics.

[0003] Whether it's common traditional sofa fabrics or these new environmentally friendly fabrics, an essential step in the production process is cutting. The entire piece of fabric needs to be cut into fixed sizes and shapes to facilitate subsequent processing and covering. With the continuous development of automation technology, the cutting of sofa fabrics is now generally completed automatically by cutting equipment.

[0004] Chinese patent ZL202411244355.5 discloses: "A sofa upholstery cutting device, comprising a machine base, a crossbeam slidably mounted above the machine base, a laser cutting module slidably mounted on one side of the crossbeam, a feeding rack at one end of the machine base with a detachable feeding roller inside the feeding rack, a discharging rack at the other end of the machine base with a detachable waste collection roller inside the discharging rack, a fixed frame on the top surface of the machine base, a smoothing scraper oscillating inside the fixed frame, and a tensioning component for cooperating to drive the smoothing scraper to oscillate. This application has the effect of improving the quality and efficiency of upholstery cutting."

[0005] However, including the solutions described in the aforementioned patents, existing sofa fabric cutting equipment on the market all have a problem: some scraps are inevitably generated during the sofa cutting process. If these scraps are allowed to fly out of the cutting equipment, they will not only pollute the working environment but also affect the health of the operators. Therefore, sofa fabric cutting machines that cut in a closed environment have also appeared on the market. These cutting machines generally have a scrap chamber connected to the closed cutting chamber, and then an air pump is installed in the cutting machine to suck the scraps into the scrap chamber. However, in actual use, since multiple cutting machines are usually started and used at the same time in the production plant, the noise of each air pump will be superimposed to produce greater noise, which will seriously affect the normal operation of the operators. Moreover, during the air pumping process, some scraps are easily sucked into the air pump, causing it to malfunction. Summary of the Invention

[0006] In order to overcome the shortcomings of existing fabric cutting equipment with scrap collection function, such as high noise and easy failure of internal air pump, this utility model provides an environmentally friendly flame-retardant fabric cutting equipment.

[0007] The technical solution of this utility model to solve its technical problem is: an environmentally friendly flame-retardant fabric cutting device, comprising:

[0008] The equipment housing has a cutting cavity inside, and the cutting cavity includes a cutting table located at the bottom of the cavity, the cutting table being used to place the fabric to be cut;

[0009] A top cover, which is flip-up and connected to the top of the device housing, allows the cutting cavity to be opened or closed by flipping the top cover.

[0010] A laser cutter is located inside the cutting cavity with its head aligned with the cutting table.

[0011] A translation mechanism is located inside the cutting cavity and mounted on the cutting table. The laser cutter is connected to the translation mechanism and can be translated above the cutting table under the drive of the translation mechanism.

[0012] The device housing also has a shredding chamber located below the cutting chamber, and the cutting table has several shredding holes, which connect the cutting chamber to the shredding chamber.

[0013] The device housing is also provided with a suction channel. The inner end of the suction channel is connected to the crushing chamber, and its outer end is opened on the rear surface of the device housing. The outer end of the suction channel can be connected to an external suction device, so that the external suction device can suck air into the crushing chamber, thereby sucking the crushed material in the cutting chamber into the crushing chamber through the crushing hole.

[0014] Furthermore, the shredding chamber is composed of a first chamber and a second chamber. The first chamber is connected to the cutting chamber through a shredding hole, and the second chamber is connected to the suction channel. A vent is also provided between the first chamber and the second chamber to connect the two.

[0015] Furthermore, the bottom surface of the first chamber is composed of a planar material accumulation section and an inclined material guiding section. The material guiding section is inclined upward from the junction with the material accumulation section. The second chamber is located below the material guiding section, and the vent is also opened on the material guiding section.

[0016] Furthermore, a material-blocking protrusion is raised on the material guide section of the first chamber, and the vent hole is opened on the peripheral wall of the material-blocking protrusion.

[0017] Furthermore, a baffle screen is provided at the connection between the second chamber and the air intake channel, and the baffle screen is densely covered with fine mesh holes.

[0018] Furthermore, the bottom of the cutting table has a window that connects the cutting cavity and the scraping cavity. Several longitudinal support rods and several transverse support rods are arranged and connected in the window. The longitudinal support rods and transverse support rods are intersected with each other, and the gap formed by the intersecting longitudinal support rods and transverse support rods is the scraping hole.

[0019] Furthermore, a discharge port is provided on the front surface of the equipment housing, which is connected to the crushing chamber. A discharge gate can also be flipped and connected to the discharge port, which can be opened or closed by flipping the discharge gate.

[0020] Furthermore, the translation mechanism includes two longitudinal linear modules arranged parallel to each other on both sides of the cutting table, and a transverse linear module is also mounted between the sliders of the two longitudinal linear modules. The laser cutter is connected to the slider of the transverse linear module.

[0021] Furthermore, the bottom of the device housing is also provided with several rollers.

[0022] This utility model relates to the fabric cutting process:

[0023] First, the staff opens the top cover, fixes the fabric to be cut inside the cutting table of the cutting chamber, and then closes the top cover. Next, the cutting equipment is turned on, activating the laser cutter and moving it with the translation mechanism to cut the fabric on the cutting table. Simultaneously, the external suction device continuously operates during the cutting process, allowing scraps generated during cutting to enter the first chamber of the scrap chamber through the scrap hole. Scraps falling into the first chamber are first drawn down to the guide section at the bottom of the first chamber by suction, then slide down and accumulate on the accumulation section. During this process, some smaller scraps inevitably enter the second chamber through the vent hole. These scraps cannot pass through the finer mesh of the baffle and therefore accumulate in the second chamber, ensuring that the air drawn from the suction channel does not carry scraps. All scraps are deposited in the first and second chambers of the scrap chamber. After cutting is complete, the top cover is opened and the fabric is removed.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The material slag chamber for accumulating slag is connected to an external suction device through a suction pipe. Compared with the solution of directly setting the air pump in the cutting machine, this cutting machine can prevent slag from leaking outside the machine. At the same time, multiple cutting machines can share a single suction device, which can effectively solve the problem of excessive noise in the factory. Furthermore, by extending the pipe to set the suction device outside the factory, the noise can be further reduced.

[0026] 2. The crushing chamber consists of a first chamber and a second chamber. The dual-chamber design ensures that the crushed material is contained within the crushing chamber, thereby preventing the crushed material from being sucked into the suction device along with the airflow.

[0027] 3. The baffle protrusion in the first chamber uses the height difference to prevent debris from entering the second chamber through the first chamber as much as possible. The baffle mesh at the connection between the second chamber and the air intake channel further blocks debris from entering the air intake channel, thereby further preventing debris from being discharged with the airflow.

[0028] 4. A discharge port and a discharge door are provided on the surface of the equipment shell. When the material in the crushing chamber accumulates to a certain amount, the discharge door can be opened to clean the material in the crushing chamber, thereby preventing excessive accumulation of material from affecting the cutting.

A vent is also provided between the first chamber 10 and the second chamber 11 for connecting the two.

[0043] Among them, such as Figure 4 As shown in the figure, the bottom surface of the first chamber 10 in this embodiment is composed of a planar material accumulation section 13 and an inclined material guiding section 14. The material guiding section 14 is inclined upward from the connection point with the material accumulation section 13. The second chamber 11 is located below the material guiding section 14, and the vent is also opened on the material guiding section 14.

[0044] Combination Figure 4 and Figure 5 As shown, in this embodiment, a material-blocking protrusion 15 is also provided on the material-guiding section 14 of the first chamber 10, and the vent hole is opened on the peripheral side wall of the material-blocking protrusion 15.

[0045] Combination Figure 4 , Figure 5 and Figure 7As shown, in this embodiment, a through opening 26 is provided on the material guiding section 14 of the first chamber 10, and the material blocking protrusion 15 is covered above the through opening 26 in a cover shape, and the material blocking protrusion 15 is detachably disposed relative to the through opening 26.

[0047] Combination Figure 3 and Figure 7 As shown, in this embodiment, the bottom of the cutting table 3 is provided with a window 18 that connects the cutting cavity 2 and the scraping cavity 7. Several longitudinal support rods 19 and several transverse support rods 20 are arranged and connected in the window 18. The longitudinal support rods 19 and transverse support rods 20 are intersected with each other. The gap formed by the intersecting longitudinal support rods 19 and transverse support rods 20 is the scraping hole 8.

[0048] Combination Figure 1 and Figure 3 As shown, in this embodiment, a discharge port 21 is also provided on the front surface of the device housing 1. The discharge port 21 is connected to the crushing chamber 7. A discharge door 22 can also be flipped and connected to the discharge port 21. The discharge port 21 can be opened or closed by flipping the discharge door 22.

[0049] Combination Figure 3 and Figure 8 As shown, in this embodiment, the translation mechanism 6 includes two longitudinal straight modules 23 arranged parallel to each other on both sides of the cutting table 3. A transverse straight module 24 is also provided between the sliders of the two longitudinal straight modules 23. The laser cutter 5 is connected to the slider of the transverse straight module 24.

[0050] Combination Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the bottom of the device housing 1 is also provided with several rollers 25.

[0051] This embodiment describes the fabric cutting process:

[0052] First, the operator opens the top cover 4, fixes the fabric to be cut inside the cutting table 3 of the cutting chamber 2, and then closes the top cover 4. Next, the cutting equipment is turned on, causing the laser cutter 5 to start and move with the translation mechanism 6, thereby cutting the fabric on the cutting table 3. Simultaneously, the external suction device continuously operates during the cutting process, allowing the scraps generated during cutting inside the cutting chamber 2 to enter the first chamber 10 of the scrap chamber 7 through the scrap hole 8. The scraps falling into the first chamber 10 are first drawn into the first chamber by suction. The material is placed on the guide section 14 at the bottom of the chamber 10, and then slides down the guide section 14 and accumulates on the accumulation section 13. During this process, some smaller pieces of material will inevitably enter the second chamber 11 through the vent. Since these pieces of material cannot pass through the mesh of the baffle 16 with smaller mesh, they will accumulate in the second chamber 11, thus ensuring that the air drawn out from the suction channel 9 does not carry any pieces of material. The pieces of material are deposited in the first chamber 10 and the second chamber 11 of the material chamber 7. After the cutting is completed, the top cover 4 can be opened to take out the fabric.

[0053] In this embodiment, the process of cleaning the debris in the debris chamber 7 is as follows:

[0054] By flipping open the discharge door 22 on the outer casing 1 of the equipment, the first chamber 10 can be exposed through the discharge port 21, so that the debris in the first chamber 10 can be removed and cleaned. By removing the cover-shaped baffle protrusion 15 from above the opening 26, the second chamber 11 can be exposed through the opening 26, and then the debris in the second chamber 11 can be removed and cleaned from the opening 26.

[0055] The advantage of this embodiment is that it can effectively reduce the noise generated during the operation of the cutting equipment, while also preventing the generated scraps from being discharged from the cutting equipment.

[0056] The above specific embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
