Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and more specifically to a polyurethane foam cutting device. Background Technology

[0002] Polyurethane foam is a high-molecular polymer made primarily from isocyanate and polyether, mixed using specialized equipment with the aid of foaming agents, catalysts, flame retardants, and other additives. It is then foamed on-site through high-pressure spraying. Widely used in the construction industry for wall decoration, polyurethane materials contribute to lightweight construction while maintaining structural strength, and polyurethane foam also offers strong earthquake resistance. After molding, the polyurethane foam needs to be cut and processed to obtain the finished product.

[0003] For example, a polyurethane foam cutting device with prior art publication number CN220218610U can guide the polyurethane foam to move laterally in a relatively stable manner during cutting, so that its position and direction remain unchanged during cutting, which is beneficial to cutting the polyurethane foam into a regular shape.

[0004] However, the existing technology described above still has the following problems in use: Traditional polyurethane foam cutting devices usually use mechanical clamps to fix the polyurethane foam during cutting. These mechanical clamps are prone to damaging the foam, affecting the cutting quality. At the same time, cutting easily generates dust, which can pollute the working environment and affect the health of workers. Therefore, this utility model provides a polyurethane foam cutting device with high cutting surface flatness and dust removal function. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a polyurethane foam cutting device. By cooperating with two vacuum adsorption platforms and two pressure plates, the polyurethane foam can be firmly fixed, which can effectively improve the stability of polyurethane foam during cutting and thus ensure the flatness of the cut surface. In addition, by using an industrial vacuum cleaner and dust removal pipe to suck up dust, the pollution of dust to the working environment is reduced to a certain extent, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane foam cutting device, comprising a processing table, two symmetrically distributed vacuum adsorption platforms fixedly mounted on the top of the processing table, each vacuum adsorption platform having an installation groove on its top, a filter plate fixedly mounted inside the installation groove, a cutting table fixedly mounted on the top of the processing table, the cutting table being positioned between the two vacuum adsorption platforms, a cutting blade mounted on the top of the cutting table, pressure plates mounted above the two vacuum adsorption platforms, a top plate fixedly mounted on the top of the processing table, and two symmetrically distributed dust removal pipes fixedly mounted on the front and rear sides of the top plate.

[0007] In a preferred embodiment, a first electric push rod and two second electric push rods are fixedly inserted through the top of the top plate. The bottom end of the piston rod of the first electric push rod is fixed to the top of the cutting blade. The cutting blade is automatically raised and lowered by means of the first electric push rod, which can effectively improve the cutting efficiency of polyurethane foam.

[0008] In a preferred embodiment, two second electric push rods are respectively located on both sides of the first electric push rod, and the bottom ends of the piston rods of the two second electric push rods are respectively fixed to the top of the two pressure plates. The pressure plates are driven to rise and fall by the second electric push rods, thereby further improving the cutting efficiency of polyurethane foam.

[0009] In a preferred embodiment, two limiting rods are fixedly provided on both the front and rear sides of the top of the cutting blade, and a limiting hole corresponding to the two limiting rods is opened on the top of the top plate. The top ends of the two limiting rods pass through the limiting hole and extend to the outside of the top plate. When the cutting blade is driven to rise and fall by the first electric push rod, the two limiting rods on the cutting blade can remain stable under the limiting effect of the limiting hole, thereby further improving the cutting stability.

[0010] In a preferred embodiment, an industrial vacuum cleaner is fixedly installed at the rear end of the top plate. The industrial vacuum cleaner is connected to multiple dust removal pipes through an air extraction pipe. The industrial vacuum cleaner automatically sucks up the dust generated during cutting to prevent the dust from spreading and polluting the working environment.

[0011] In a preferred embodiment, the processing table has multiple equally spaced fixing holes on both the front and rear sides of the top. These fixing holes are located on the outside of the vacuum adsorption platform. The design of multiple fixing holes can effectively improve the stability of the processing table, thereby improving the flatness of the polyurethane foam cutting.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses two vacuum adsorption platforms and two pressure plates to form a firm fixation for polyurethane foam, which can effectively improve the stability of polyurethane foam during cutting and thus ensure the flatness of the cut surface. At the same time, the cutting blade can automatically rise and fall to complete the cutting, which greatly improves the cutting efficiency. Furthermore, the industrial vacuum cleaner and dust removal pipe are used to suck up dust, which reduces the pollution of the working environment by dust to a certain extent.

[0014] 2. By installing filter plates on the top of both vacuum adsorption platforms, dust can be blocked, preventing dust from clogging the holes on the vacuum adsorption platforms. At the same time, the filter plates are installed in the mounting slots, making them easy to disassemble and maintain. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Refer to the instruction manual appendix Figures 1-5This utility model provides a polyurethane foam cutting device, including a processing table 1. Two symmetrically distributed vacuum adsorption platforms 2 are fixedly installed on the top of the processing table 1. Each of the two vacuum adsorption platforms 2 has an installation groove 3 on its top. A filter plate 4 is fixedly installed inside the installation groove 3. A cutting table 5 is fixedly installed on the top of the processing table 1 between the two vacuum adsorption platforms 2. A cutting blade 6 is installed on the top of the cutting table 5. A pressure plate 7 is installed above each of the two vacuum adsorption platforms 2. A top plate 8 is fixedly installed on the top of the processing table 1. Two symmetrically distributed dust removal pipes 9 are fixedly installed on the front and rear sides of the top plate 8.

[0023] Vacuum adsorption platform 2 is a device that uses vacuum technology to generate negative pressure to adsorb and fix workpieces. It typically includes a vacuum pump, vacuum tank, adsorption plate, suction nozzle, filter, control system, etc. The vacuum degree is generated by the vacuum pump or vacuum generator, forming a pressure difference below the adsorption plate, and atmospheric pressure is used to firmly adsorb polyurethane foam onto the platform.

[0024] The top plate 8 is fixedly perforated by a first electric push rod 10 and two second electric push rods 11. The bottom end of the piston rod of the first electric push rod 10 is fixed to the top of the cutting blade 6. The two second electric push rods 11 are respectively located on both sides of the first electric push rod 10, and the bottom ends of the piston rods of the two second electric push rods 11 are respectively fixed to the top of the two pressure plates 7.

[0025] An industrial vacuum cleaner 14 is fixedly installed at the rear end of the top plate 8. The industrial vacuum cleaner 14 is connected to multiple dust collection pipes 9 through an air extraction pipe. The industrial vacuum cleaner 14 is a high-power vacuuming device designed specifically for industrial environments. The electric exhaust fan runs at high speed, creating an instantaneous vacuum inside the vacuum cleaner. Under the action of air pressure difference, dust and dirt enter the barrel with the airflow, and then pass through the dust collection bag for filtration. The dirt is left in the dust collection bag, and the purified air escapes.

[0026] In actual use, the operator first places the polyurethane foam to be cut on the vacuum adsorption platform 2 on the top left of the processing table 1, and pulls the right end of the polyurethane foam to the vacuum adsorption platform 2 on the top right of the processing table 1. Then, the second electric push rod 11 extends to drive the pressure plate 7 to press down on the polyurethane foam. The vacuum adsorption platform 2 and the pressure plate 7 work together to firmly press the polyurethane foam, which can improve the stability of the polyurethane foam during cutting and thus improve the flatness of the cut surface. Subsequently, the first electric push rod 10 extends to drive the cutting blade 6 to descend, and the cutting blade 6 automatically cuts the polyurethane foam, improving the cutting efficiency. During the cutting process, the industrial vacuum cleaner 14 generates suction, and the dust generated during cutting is sucked into the industrial vacuum cleaner 14 through the dust collection pipe 9, which can reduce the pollution of the working environment by dust to a certain extent.

[0027] Refer to the instruction manual appendix Figure 1 , Figure 2 and Figure 5 Two limiting rods 12 are fixedly provided on the front and rear sides of the top of the cutting blade 6. The top of the top plate 8 is provided with limiting holes 13 corresponding to the two limiting rods 12. The top ends of the two limiting rods 12 pass through the limiting holes 13 and extend to the outside of the top plate 8. When the first electric push rod 10 drives the cutting blade 6 to rise and fall, the two limiting rods 12 on the cutting blade 6 can remain stable under the restriction of the limiting holes 13, thereby further improving the cutting stability.

[0028] like Figure 1 and Figure 4 As shown, the processing table 1 has multiple equally spaced fixing holes 15 on both the front and rear sides of the top, and the multiple fixing holes 15 are all located on the outside of the vacuum adsorption platform 2. The design of multiple fixing holes 15 can effectively improve the stability of the processing table 1, thereby improving the flatness of the polyurethane foam cutting.

[0029] Either the first electric push rod 10 or the second electric push rod 11 can be selected. An electric push rod is an electrically driven device that converts the rotary motion of an electric motor into the linear reciprocating motion of a push rod. It mainly consists of a drive motor, reduction gears, a screw, a nut, a guide sleeve, a push rod, a slide, a spring, a housing, a worm gear, and a micro-control switch. The motor, after being reduced in speed by gears or a worm gear, drives a pair of lead screws and nuts, converting the motor's rotary motion into linear motion. The forward and reverse rotation of the motor completes the extension and retraction of the push rod. When the set stroke is reached, the limit switch cuts off the power, stopping the motor. Since this is existing conventional technology, it will not be described in detail here.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
