Description

Technical Field

[0001] This utility model relates to the technical field of foam cutting devices, specifically to a foam cutting device that prevents deviation. Background Technology

[0002] Foam is a material made by foaming plastic particles. Foam is divided into PU foam, antistatic foam, conductive foam, EPE, antistatic EPE, PORON, CR, EVA, crosslinked PE, SBR, EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixing, convenient use, flexible bending, ultra-thin size, and reliable performance.

[0003] When foam is produced and used, it needs to be cut into corresponding shapes, such as rectangular shapes. For example, a foam cutting device disclosed in patent announcement number CN211566069U states that "when foam is produced and used, it needs to be cut into corresponding shapes, and rectangular and strip-shaped foams are the most widely used." Therefore, cutting foam into rectangular shapes is also a shape that is commonly used in the market.

[0004] Meanwhile, when cutting foam, foam cutting devices are usually used, mainly for die cutting. However, when a whole piece of foam is placed on the cutting table of the cutting device for die cutting, because the foam is too light, an airflow is generated during the downward movement of the die. This airflow blows towards the foam placed on the cutting table, causing its position to shift.

[0005] Based on this, a foam cutting device for preventing displacement is proposed. Utility Model Content

This device addresses the issue that when a whole piece of foam is placed on the cutting table of the cutting device for molding and cutting, the foam is too light, and an airflow is generated during the downward movement of the mold. This airflow blows onto the foam placed on the cutting table, causing its position to shift.

[0024] This utility model provides a foam cutting device to prevent displacement, solving the problem that when a whole piece of foam is placed on the cutting table of the cutting device for molding and cutting, the foam is too light, and an airflow is generated during the downward movement of the mold. This airflow blows towards the foam placed on the cutting table, causing its position to shift. The specific technical solution is as follows: Example 1 like Figures 1-6 As shown in the figure, an embodiment of the present invention provides a foam cutting device for preventing deviation, comprising: The cutting base 100 is U-shaped, with a vacuum adsorption chamber 110 at the bottom and both sides of the vacuum adsorption chamber 110 are open. Cover plates 120 are fixedly installed at both ends of the vacuum adsorption chamber 110, and the top of the vacuum adsorption chamber 110 has an adsorption channel. The entire piece of foam to be cut is placed on the cutting base 100 and can be fixed by vacuum airflow through the adsorption channel to prevent its position from shifting. A fixing plate 200 is fixedly installed between the tops of the two side walls of the cutting base 100; The cutting die 300 is located below the fixed plate 200 and is slidably installed between the two side walls of the cutting base 100; A hydraulic cylinder 400 is fixedly mounted at the top center of a fixed plate 200, and the hydraulic rod of the hydraulic cylinder 400 extends downward through the fixed plate 200, with its end face fixedly connected to the top center of the cutting die 300; and A vacuum adsorption assembly 500 is mounted on one of the cover plates 120 and is connected to the vacuum adsorption chamber 110.

[0025] In this embodiment, the entire piece of foam to be cut is placed on the cutting base 100, the vacuum adsorption assembly 500 is activated, and a vacuum airflow is generated in the vacuum adsorption chamber 110. The foam is adsorbed and fixed through the adsorption channel composed of multiple vacuum adsorption holes 130. Then, the hydraulic cylinder 400 drives the cutting die 300 to move down to perform molding and cutting on the foam.

[0026] Example 2 like Figures 1-6 As shown, the improvements are based on Example 1: Furthermore, the adsorption channel is composed of multiple vacuum adsorption holes 130, which are opened at the center of the top of the inner cavity of the vacuum adsorption chamber 110 and are equidistantly distributed along the length of the cutting base 100.

[0027] In this embodiment, multiple equidistantly distributed vacuum adsorption holes 130 constitute an adsorption channel, which allows the vacuum airflow to act uniformly on the foam, improves adsorption stability, and prevents the foam from shifting.

[0028] Furthermore, the bottom of the cutting die 300 has several spiral cutting heads 310, which are distributed in a matrix at the bottom of the cutting die 300. Each of the spiral cutting heads 310 is integrally formed with the cutting die 300.

[0029] In this embodiment, the matrix-distributed spiral cutting heads 310 can simultaneously perform multi-area molding cuts on the foam to cut it into multiple rectangular foam sheets; the one-piece molding structure ensures the strength and cutting accuracy of the cutting heads.

[0030] Furthermore, one of the cover plates 120 has a suction port 1210 on its outer side wall. The suction port 1210 is integrally formed with the cover plate 120, and its inner cavity is connected to the vacuum adsorption cavity 110. The vacuum adsorption assembly 500 is detachably mounted on the suction port 1210.

[0031] In this embodiment, the suction port 1210 provides an interface for the connection between the vacuum adsorption component 500 and the vacuum adsorption chamber 110, and its detachable design facilitates the installation and maintenance of the component.

[0032] Furthermore, the vacuum adsorption assembly 500 includes a vacuum generator 510 and a solenoid valve 540. The vacuum generator 510 has a vacuum suction port 520 and a compressed air inlet port 530. The vacuum suction port 520 is inserted into the suction port 1210. The vacuum generator 510 also has an exhaust port on the side away from the compressed air inlet port 530, and the exhaust port is set outward. The solenoid valve 540 has a valve body outlet port 550, which is plugged into the compressed air inlet port 530. The solenoid valve 540 also has a valve body air inlet port 560, which is connected to the air pipe (not shown in the figure) of the vacuum air source in the workshop.

[0033] In this embodiment, after the air pipe of the vacuum source in the workshop is connected to the valve body air inlet port 560 on the solenoid valve 540, the solenoid valve 540 controls the compressed air to enter the vacuum generator 510. The vacuum generator 510 generates a vacuum airflow in the vacuum adsorption chamber 110 through the vacuum suction port 520 and the suction port 1210, and then adsorbs and fixes the foam through the adsorption channel.

[0034] Example 3 like Figures 1-6 As shown, the improvements are based on Example 1: Furthermore, a sliding guide structure is provided between the cutting die 300 and the cutting base 100.

[0035] In this embodiment, the sliding guide structure provides guidance for the up-and-down movement of the cutting die 300, ensuring positional accuracy during cutting.

[0036] Furthermore, the sliding guide structure includes guide grooves 140 formed on both sides of the inner sidewall of the cutting base 100 and guide sliders 320 provided at both ends of the opposite sidewall of the cutting die 300 and corresponding to the guide grooves 140. Each guide slider 320 is integrally formed with the cutting die 300; Each guide slider 320 is slidably installed in its corresponding guide groove 140.

[0037] In this embodiment, the guide slider 320 slides within the guide groove 140 to achieve stable guidance of the cutting die 300 and avoid deviation during cutting.

[0038] The different embodiments described above can be combined, substituted, or used in combination with each other.

[0039] Work steps: like Figures 1-6 As shown, the entire piece of foam to be cut is placed on the cutting base 100. The vacuum adsorption assembly 500 generates a vacuum airflow in the vacuum adsorption chamber 110. This vacuum airflow then adsorbs and fixes the foam through an adsorption channel formed by multiple equidistantly distributed vacuum adsorption holes 130. Specifically: After the air pipe of the vacuum source in the workshop is connected to the valve body air inlet port 560 on the solenoid valve 540, the solenoid valve 540 controls the compressed air to enter the vacuum generator 510. The vacuum generator 510 generates a vacuum airflow in the vacuum adsorption chamber 110 through the vacuum suction port 520 and the suction port 1210, and then adsorbs and fixes the foam through the adsorption channel. Subsequently, the hydraulic cylinder 400 drives the cutting die 300 to move down along the sliding guide structure formed by the guide groove 140 and the guide slider 320, and uses the bottom matrix-distributed spiral cutting heads 310 to perform molding and cutting of the foam, so that it is cut into multiple rectangular foam sheets; during the cutting process, vacuum adsorption always keeps the foam position stable and avoids displacement.

[0040] In summary: 1. The adsorption channel formed by the vacuum adsorption chamber 110 and the vacuum adsorption hole 130 can effectively adsorb and fix the foam by using the vacuum airflow, preventing the foam from shifting due to the airflow when the mold moves down, and ensuring the accuracy of the cutting position.

[0041] 2. The bottom matrix-distributed spiral cutting head 310 of the cutting die 300 is integrally formed, which can perform multi-area cutting at the same time, improving cutting efficiency and consistency. The matrix-distributed spiral cutting head 310 can simultaneously perform multi-area molding and cutting of foam to cut it into multiple rectangular foam sheets.

[0042] Third, the sliding guide structure makes the downward movement of the cutting die 300 smooth, avoids deviation during cutting, and further ensures cutting accuracy.

[0043] Fourth, the detachable design of the vacuum adsorption component 500 and the control of the solenoid valve 540 facilitate the installation, maintenance and flexible control of the vacuum adsorption, thereby improving the practicality and operability of the device.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
