Description

Technical Field

[0001] This utility model relates to the field of curtain cutting equipment, and in particular to a curtain scrap cutting device. Background Technology

[0002] For curtain fabrics with different hem shapes, during the production process, the entire curtain fabric is laid out on the working platform of the fabric laser cutting machine. The laser cutting head is driven to move to a set position and moves along a set path to cut off the excess material of the curtain fabric and cut out the required hem shape.

[0003] Because laser cutting is used, the cutting principle is to generate a high-energy-density laser beam that irradiates the fabric. The fabric surface will quickly absorb the laser energy and be heated to the melting or vaporization temperature. As the temperature rises, the material on the fabric surface begins to vaporize, forming steam. This steam is blown away by the high-speed airflow, thus forming a cut in the curtain fabric. During the cutting process, the curtain fabric will produce a small amount of molten tar. The tar adheres to the steel wire mesh of the machine that carries the fabric and becomes very hard after cooling, making it difficult to clean. If it is not cleaned for a long time, it will accumulate on the steel wire mesh, thus damaging the curtain fabric when it is dragged on the steel wire mesh. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a curtain scrap cutting device that automatically cleans the tar adhering to the surface of the supporting wire mesh after cutting, saving manpower and avoiding damage to the curtain fabric.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A curtain scrap cutting device includes a machine base, a load-bearing steel wire mesh fixed in the middle of the upper inner wall of the machine base, an X-axis moving component fixed on the top surface of the machine base, a Y-axis moving component fixed in the middle of the moving end of the X-axis moving component, a laser cutting head fixed in the moving end of the Y-axis moving component, the laser cutting head facing the load-bearing steel wire mesh, and a shielding cover covering the outside of the Y-axis moving component fixed in the middle of the moving end of the X-axis moving component.

[0007] A scraper is rotatably mounted on one side of the outer wall of the shield. The length direction of the scraper and the axial direction of the scraper's flipping axis are the same as the driving direction of the Y-axis moving component. A wiping component is fixed at the lower end of the outer wall of the scraper away from the supporting wire mesh. When the scraper flips to the point where the outer wall is in contact with the top surface of the supporting wire mesh, the wiping surface of the wiping component is also in contact with the top surface of the supporting wire mesh.

[0008] A flipping assembly for driving the scraper to flip is also installed between the shield and the outer wall of the scraper.

[0009] Preferably, the wiping assembly includes a plurality of connecting posts fixed side by side along the length of the scraper to the lower end of the outer wall of the scraper on the side away from the supporting wire mesh. A connecting strip is fixed to the side of the plurality of connecting posts away from the scraper, and a wire brush is fixed to the side of the connecting strip close to the supporting wire mesh.

[0010] Preferably, the connecting strip has a hollow inner cavity formed on the side away from the supporting wire mesh. A vibration assembly for the vibrating connecting strip is fixed to the inner wall of the inner cavity. The vibration assembly includes several motors fixed to the inner wall of the inner cavity. A rubber flexible shaft is fixed to the output end of the motor. The axis of the rubber flexible shaft is perpendicular to the axis of the output shaft of the motor. A striking ball is fixed to the end of the rubber flexible shaft away from the output shaft of the motor. A receiving block is fixed on the inner wall of the inner cavity at the position corresponding to the striking ball.

[0011] Preferably, the flipping assembly includes an electric push rod rotatably connected to the outer wall of the shield near the scraper via a pivot pin, and the extended end of the electric push rod is rotatably connected to the outer wall of the scraper via a pivot pin.

[0012] Preferably, the bearing wire mesh consists of several warp wires arranged side by side at equal intervals and several weft wires arranged side by side at equal intervals. The weft wires are located above the warp wires, and each weft wire is fixed to several warp wires. The warp wires are fixed to the inner wall of the upper end of the machine platform. The length direction of the weft wires is perpendicular to the length direction of the scraper, and the length direction of the weft wires is the same as the driving direction of the X-axis moving component.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model adds a rotatable scraper and an electric push rod to the outside of the shielding cover. The scraper is equipped with a wire brush. After the curtain fabric is cut, the electric push rod drives the scraper to flip so that it is in close contact with the supporting wire mesh. The shielding cover is moved by the X-axis moving component to scrape off and use the wire brush to deeply clean the tar on the wire mesh, avoiding damage to the curtain fabric, realizing automated cleaning and saving manpower.

[0015] 2. By setting up a structure such as a motor, a striking ball, and a receiving block, this utility model can generate vibration of the connecting strip by the high-frequency impact of the striking ball on the receiving block during the scraping process, thereby accelerating the separation of the scraped impurities from the wire brush.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, please refer to Figures 1 to 4 This embodiment provides a curtain scrap cutting device, including a machine base 1. A supporting steel wire mesh 2 is provided in the middle of the upper inner wall of the machine base 1. The supporting steel wire mesh 2 is composed of several warp wires 201 arranged at equal intervals and several weft wires 202 arranged at equal intervals. The weft wires 202 are located above the warp wires 201, and each weft wire 202 is fixed to several warp wires 201 respectively. The warp wires 201 are fixed to the upper inner wall of the machine base 1. An X-axis moving component 3 is fixed on the top surface of the machine base 1. A Y-axis moving component 4 is fixed in the middle of the moving end of the X-axis moving component 3. A laser cutting head 5 is fixed in the moving end of the Y-axis moving component 4. The laser cutting head 5 faces the supporting steel wire mesh 2. A shielding cover 6 covering the outside of the Y-axis moving component 4 is fixed in the middle of the moving end of the X-axis moving component 3.

[0024] The leftover curtain fabric to be cut is laid flat on the supporting wire mesh 2. By driving the X-axis moving component 3 to work, the Y-axis moving component 4 is moved along the X-axis direction. The Y-axis moving component 4 is working, which in turn drives the laser cutting head 5 to move along the Y-axis direction on the Y-axis moving component 4. This allows the laser cutting head 5 to move along a preset path to complete the cutting of the curtain fabric according to the required pattern, separating the leftover fabric from the main body of the curtain.

[0025] A scraper 7 is rotatably mounted on one side of the outer wall of the shield 6. The length direction of the scraper 7 and the axial direction of the rotating axis of the scraper 7 are the same as the driving direction of the Y-axis moving component 4. The length direction of the weft wire 202 is perpendicular to the length direction of the scraper 7, and the length direction of the weft wire 202 is the same as the driving direction of the X-axis moving component 3. This ensures that the scraper 7 can always be in contact with the surface of the weft wire 202 during the process of scraping tar by moving back and forth above the machine 1 driven by the X-axis moving component 3, thus ensuring that the tar on the surface of the weft wire 202 can be fully scraped off.

[0026] An electric push rod 15 is rotatably connected to the outer wall of the shield 6 near the scraper 7 via a shaft pin. The extended end of the electric push rod 15 is rotatably connected to the outer wall of the scraper 7 via a shaft pin.

[0027] After the curtain fabric is cut and cut, the X-axis moving component 3 moves the Y-axis moving component 4 to one end of the carrying wire mesh 2. Then, the electric push rod 15 is driven to extend, so that the scraper 7 flips and abuts against the surface of the carrying wire mesh 2. Then, the X-axis moving component 3 drives the scraper 7 to move together with the Y-axis moving component 4 from one end of the carrying wire mesh 2 to the other end, so as to scrape off the tar on the surface of the carrying wire mesh 2 by the scraper 7.

[0028] The scraper 7 is located away from the lower end of the outer wall of the side bearing the wire mesh 2. Several connecting posts 8 are fixed side by side along the length of the scraper 7. A connecting strip 9 is fixed on the side of the connecting posts 8 away from the scraper 7. A wire brush 10 is fixed on the side of the connecting strip 9 close to the bearing wire mesh 2.

[0029] After the tar is scraped off, the X-axis moving component 3 drives the scraper 7 to move back and forth between the two ends of the supporting wire mesh 2, and uses the wire brush 10 to continuously brush the debris to achieve a deep cleaning effect.

[0030] Because it can automatically clean the tar on the surface of the steel wire mesh 2, it avoids the accumulation of tar that could damage the curtain fabric, and it does not require manual cleaning, thus greatly saving manpower.

[0031] Example 2, please refer to Figure 5 This embodiment provides a further technical solution based on embodiment one. The connecting strip 9 has a hollow inner cavity 901 on the side away from the bearing wire mesh 2. Two motors 11 are fixed on the inner wall of the inner cavity 901. A rubber flexible shaft 12 is fixed at the output end of the motor 11. The axis of the rubber flexible shaft 12 is perpendicular to the axis of the output shaft of the motor 11. A hitting ball 13 is fixed at the end of the rubber flexible shaft 12 away from the output shaft of the motor 11. A receiving block 14 is fixed on the inner wall of the inner cavity 901 at the position corresponding to the hitting ball 13.

[0032] While the wire brush 10 performs deep cleaning, the motor 11 rotates at high speed, driving the striking ball 13 to strike the receiving block 14 at high frequency, which vibrates the connecting strip 9, accelerating the removal of impurities from the wire brush 10 and achieving a self-cleaning effect.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
