Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically a foam glass cutting machine. Background Technology

[0002] Foam glass is a high-performance, lightweight, high-strength, and environmentally friendly material. A foam glass cutting machine is a mechanical device used to cut foam glass materials. It is usually composed of a table, laser generator, cutting head, control cabinet, and three-axis displacement table.

[0003] In the equipment's workflow, the foam glass to be processed is first placed stably on the platform. Then, the laser generator produces a high-energy-density laser beam, which is precisely focused and output by the cutting head. At the same time, the three-axis displacement stage moves the cutting head flexibly and precisely according to the preset instructions input on the control panel on the control cabinet, so that it forms the required cutting trajectory in three-dimensional space, thereby efficiently completing the cutting operation.

[0004] However, in actual cutting operations, a certain amount of powder will inevitably be generated. If this powder is not cleaned up in time, it will contaminate the surface of the foam glass when it is placed later, and may even affect the stability of the cutting. The spread of powder will also pollute the working environment and endanger the health of the operators. In addition, the method of placing the foam glass directly on the table lacks effective fixing measures, and it is very easy to have slight displacement during the cutting process, which will also have an adverse effect on the cutting accuracy.

[0005] Therefore, in order to solve the above problems, a foam glass cutting machine is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a foam glass cutting machine with functions of adsorbing powder and pressing, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foam glass cutting machine, including a table, wherein the table is evenly provided with feeding holes, a box is fixedly installed on the lower side of the table, a vacuum pump is connected to the lower side of the box, a partition is installed inside the box, a through hole is evenly provided in the center of the partition, a filter screen assembly is inserted into the through hole, a pair of sealing screw modules are fixedly installed on the upper side of the partition, a cleaning assembly is installed between the slides of the pair of sealing screw modules through a support frame, and the cleaning assembly is sleeved on the outside of the filter screen assembly;

[0008] An electric cylinder is fixedly installed on the lower side of the housing. The lower end of the electric cylinder is fixedly installed with the same I-beam. One end of a column is rotatably installed on both the left and right sides of the I-beam. A guide pin is fixedly installed on the other end of the column and on the side near the filter assembly. Each guide pin is fitted with a pressure plate. A guide assembly for changing the direction of the guide pin is installed on the upper side of the platform.

[0009] Specifically, the filter assembly includes a flange ring, a cylindrical support mesh, and a filter bag. The cylindrical support mesh is fixedly installed inside the flange ring, and the filter bag is fitted onto the cylindrical support mesh. The filter bag is inserted into the through hole. The flange ring is installed on the lower side of the partition plate by screws, and the lower edge of the filter bag is clamped between the flange ring and the partition plate.

[0010] Specifically, the cleaning assembly includes an internally threaded cylinder, an externally threaded cylinder, and an annular brush. The support frame is uniformly and fixedly installed with internally threaded cylinders. Externally threaded cylinders are screwed into the interior of each internally threaded cylinder. An annular brush is fixedly installed inside each externally threaded cylinder. The interior of the annular brush abuts against the filter bag.

[0011] Specifically, the guide assembly includes a sleeve, a vertical guide groove, and a spiral guide groove. The platform has a through hole for the column to pass through. The sleeve is fixedly installed on the upper side of the platform. The upper end of the column is inserted into the sleeve. The sleeve has a continuous vertical guide groove and a spiral guide groove on the side near the filter assembly. The vertical guide groove is located below the spiral guide groove. The guide pin is slidably installed in the continuous guide groove and spiral guide groove.

[0017] Based on the partitions, filter components, and vacuum pumps installed in the cabinet, it can adsorb and filter the powder on the cutting platform during the cutting operation, so as to avoid affecting the placement of the foam glass below and also avoid the impact of dust on the working environment.

[0018] The combination of the sealing screw module and cleaning components allows for cleaning of the filter assembly during or outside of cutting operations, preventing a decrease in filtration efficiency due to dust adhering to the filter bag.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 and Figure 2 This utility model provides a technical solution:

[0028] A foam glass cutting machine includes a table 7 for placing foam glass. The table 7 has uniformly spaced feeding holes 10. A housing 13 is fixedly installed on the lower side of the table 7 by bolts. A vacuum pump 16 is connected to the lower side of the housing 13. A partition 14 is installed inside the housing 13, separating the interior of the housing 13 into an upper collection chamber and a lower negative pressure chamber. Through holes are uniformly spaced at the center of the partition 14 in a rectangular array. A filter assembly 8 is inserted into the through holes to prevent powder from entering the negative pressure chamber from the collection chamber. A pair of sealing screw modules 12 are fixedly installed on the upper side of the partition 14. The sealing screw modules 12 are existing equipment and are vertically arranged. A cleaning assembly 9 is installed between the slides of the pair of sealing screw modules 12 by a support frame 11. The cleaning assembly 9 is sleeved on the outside of the filter assembly 8 and is used to brush away the powder adhering to the filter assembly 8.

[0029] When the vacuum pump 16 is working, it draws air from above the platform 7 into the collection chamber through the feeding hole 10. After being filtered by the filter assembly 8, the clean air passes through the negative pressure chamber and the vacuum pump 16 and is discharged. The powder is retained on the partition 14 for collection. At the same time, the sealing screw module 12 moves up and down to clean the cleaning assembly 9, cleaning the powder adhering to the surface of the filter assembly 8. The negative pressure in the collection chamber also helps to adsorb the foam glass placed on the platform 7.

[0030] Specifically, two electric cylinders 2 are fixedly installed on the lower side of the housing 13. The electric cylinders 2 are symmetrically arranged. The same I-beam 1 is fixedly installed at the lower end of the electric cylinder 2. One end of the column 4 is rotatably installed on the left and right sides of the I-beam 1 through bearings. The other end of the column 4 and the side close to the filter assembly 8 are fixedly installed with guide pins 17. Each guide pin 17 is equipped with a pressure plate 6. A guide assembly 5 for changing the direction of the guide pins 17 is installed on the upper side of the platform 7. The electric cylinder 2 is used to lift the I-beam 1 and the column 4. The guide assembly 5 will change the orientation of the guide pins 17 and the pressure plate 6 when the column 4 is lifted. That is, when it moves down, the pressure plate 6 faces the filter assembly 8, which is conducive to pressing foam glass of different thicknesses. When it moves up, the pressure plate 6 faces the front along with the guide pin 17, which can avoid the working space for placing and picking up foam glass and improve the convenience of operation.

[0031] Please see Figure 5The filter assembly 8 includes a flange ring 81, a cylindrical support mesh 82, and a filter bag 83. The cylindrical support mesh 82 is fixedly installed inside the flange ring 81, and the filter bag 83 is sleeved on the cylindrical support mesh 82. The filter bag 83 is inserted into the through hole. The flange ring 81 is installed on the lower side of the partition plate 14 by screws, and the lower edge of the filter bag 83 is clamped between the flange ring 81 and the partition plate 14. The flange ring 81 is used to provide an installation base, and the cylindrical support mesh 82 can fully support the filter bag 83, avoiding the problem of incomplete cleaning due to insufficient contact of the cleaning assembly 9. The clamping installation method of the filter bag 83 also facilitates replacement and installation.

[0032] The cleaning component 9 includes an internally threaded cylinder 91, an externally threaded cylinder 92, and an annular brush 93. The internally threaded cylinders 91 are evenly fixedly installed on the support frame 11, and the internally threaded cylinders 91 are aligned with the through holes. The internally threaded cylinders 91 are all screwed with externally threaded cylinders 92, and the internally threaded cylinders 92 are all fixedly installed with annular brushes 93. The bristles of the annular brushes 93 face inward, and the inside of the annular brushes 93 abuts against the filter bag 83. The annular brushes 93 can be easily replaced by the externally threaded cylinders 92, avoiding the problem of insufficient contact caused by wear after long-term use, and the replacement is convenient.

[0033] Please see Figure 3 The guide assembly 5 includes a sleeve 53, a vertical guide groove 51, and a spiral guide groove 52. The platform 7 has a through hole for the column 4 to pass through. The sleeve 53 is fixedly installed on the upper side of the platform 7. The upper end of the column 4 is inserted into the sleeve 53. The sleeve 53 has a vertical guide groove 51 and a spiral guide groove 52 continuously formed on the side of the sleeve 53 near the filter assembly 8. The vertical guide groove 51 is located below the spiral guide groove 52. The guide pin 17 is slidably installed in the continuous guide groove 51 and spiral guide groove 52. The left spiral guide groove 52 rotates clockwise from bottom to top, and the right spiral guide groove 52 rotates counterclockwise from bottom to top. Here, "clockwise" and "counterclockwise" are used as references from the top view. When the column 4 moves upward, the guide pin 17 slides along the continuous guide groove 51 and spiral guide groove 52, gradually swinging the pressure plate 6 forward. Conversely, when the column 4 moves downward, it gradually returns to the side near the filter assembly 8.

[0034] Pressure sensors 3 are fixedly installed between the lower end of the electric cylinder 2 and the I-beam 1. The pressure sensors 3 are used to apply pressure to the electric cylinder 2 on the I-beam 1, thereby indirectly knowing the force of the pressure plate 6 pressing the foam glass and ensuring that the pressing pressure is appropriate.

[0035] The pressure plate 6 is connected to the guide pin 17 by bolts; the appropriate length of the pressure plate 6 can be replaced according to the size of the foam glass to match the pressing requirements, which is widely used and easy to replace.

[0036] The partition 14 forms a conical recess downwards; the conical recess facilitates the collection of powder and makes it convenient for centralized processing.

[0037] Please see Figure 4 The front of the box 13 is hinged with a pair of doors. Support rails 15 are fixedly installed on both the left and right sides inside the box 13. Rubber pads 18 are embedded around the partition 14. The cross-section of the rubber pads 18 is L-shaped, which is used to seal the airtightness of the partition 14 when it comes into contact with the box 13 and the doors. The partition 14 can be installed into the box 13 along the support rails 15 or removed from the box 13. All components set on the partition 14 can be maintained, and the collected dust can be cleaned from the outside.

[0038] The vacuum pump 16, the sealing screw module 12, the pressure sensor 3 and other electrical components are electrically connected to the external control cabinet and controlled uniformly through the control panel.

[0039] The working principle of this embodiment:

[0040] When cutting foam glass, vacuum pump 16 also works simultaneously. For foam glass that is heavy and / or has a large area, pressure plate 6 can be used without assistance. The negative pressure generated at the discharge hole 10 can help with adsorption and positioning, and there will be no displacement during cutting. However, for foam glass that is light and / or has a small area, pressure plate 6 is required. Electric cylinder 2 moves column 4 down via I-beam 1, and guide pin 17 slides along continuous guide groove 51 and spiral guide groove 52. At the same time, column 4 is adapted to rotate, rotating pressure plate 6 from the initial position at the front to the side close to filter assembly 8 and continuing to move down until it presses the foam glass to the set force before cutting.

[0041] The powder generated during cutting enters the collection chamber and is filtered by the filter assembly 8 and stored on the partition 14. At the same time, the sealing screw module 12 moves the cleaning assembly 9 up and down to clean the powder adhering to the surface of the filter assembly 8 online, so as to avoid the powder adhering to the filter bag 83 and affecting the real-time filtration effect. In addition, the cleaning assembly 9 can also be driven by the sealing screw module 12 to clean the powder when cutting is not in progress and when the vacuum pump 16 is not working, resulting in a better peeling effect.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
