Description

Technical Field

[0001] This utility model relates to the field of foam technology, and in particular to foam cutting equipment. Background Technology

[0002] Foam is a material made by foaming plastic particles. Due to its advantages such as elasticity, light weight, quick pressure-sensitive fixing, ease of use, flexibility, ultra-thin thickness, and reliable performance, it can be widely used in industries such as sofas, mattresses, clothing, and soft packaging.

[0003] Foam can be foamed and molded to achieve the required elasticity and density. After foaming, the foam will form a relatively long shape within the mold cavity, such as the foaming tank. For regular shapes and reasonable sizes, the foam needs to be cut into smaller pieces after foaming, and the outer contour of the foam needs to be trimmed. However, due to the soft nature of foam, the area near the cut edge is easily deformed by pressure during cutting. Therefore, the edges of the foam often need to be repeatedly trimmed and refined. In the industry, this is usually done by workers using hand-held cutting tools, which is not only inefficient but can also sometimes cause further deformation due to human error, leading to an increase in defective products. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a foam cutting device to solve the above problems.

[0005] The present invention adopts the following technical solution:

[0006] This utility model first provides a foam cutting device, which includes a machine tool, a foam support table and a cutting section.

[0007] The machine tool is provided with a transverse lead screw and two transverse guide rails on both sides of the transverse lead screw, and each of the two transverse guide rails is provided with a sliding seat, so that the sliding seat can move along the transverse guide rail;

[0008] The foam support platform has a limiting groove in the horizontal direction. A limiting stop is provided in the limiting groove. The top of the limiting stop is higher than the platform. The limiting stop can move along the limiting groove and is used to abut against the edge of the foam placed on the platform to limit the foam. The front and rear ends of the foam support platform are respectively connected to two sliding seats, which span across and are fixed to the nut seat set by the lead screw. It is driven by a horizontal drive motor set on the machine tool to drive the foam support platform to move back and forth in the horizontal direction.

[0009] The cutting section includes a pair of guide rail posts, pulley seats, a vertical lead screw, and heating wire mounting blocks. The two guide rail posts are respectively arranged opposite each other on the front and rear sides of the machine tool. The pulley seats are fixed on the nut seats of the vertical lead screw and can roll along the guide rail posts. The heating wire mounting blocks are locked onto the pulley seats and are arranged opposite each other. A heating wire is installed between the two heating wire mounting blocks. The pulley seats are driven by a lifting drive motor arranged on the vertical lead screw, which drives the heating wire to rise and fall to cut the foam.

[0010] Preferably, the foam support platform has a cutting clearance groove on its surface, which extends longitudinally from the front end of the foam support platform to its rear end and is perpendicular to the limiting groove.

[0011] Preferably, a scale is provided on the edge of the foam support platform.

[0012] Preferably, the surface of the foam support platform is covered with an anti-slip polyurethane layer.

[0013] Preferably, the heating wire mounting block has a beveled relief groove extending vertically from its top to its bottom.

[0014] Preferably, the lateral drive motor and the lifting drive motor are respectively connected to a control console via signals, so that the start and stop of the lateral drive motor and the lifting drive motor can be controlled by the control console.

[0015] Preferably, the front and rear sides of the machine tool are respectively provided with support columns in the same longitudinal direction, and the two guide rail columns are correspondingly locked to the support columns for opposite fixation.

[0016] The technical effects achieved by this utility model include:

[0017] The horizontal lead screw and guide rail enable the foam support platform to move precisely laterally, while the limiting groove and stop bar design ensure the foam's position is fixed during cutting, preventing deformation. The cooperation of the guide rail column, pulley seat, and vertical lead screw in the cutting section allows the heating wire to move precisely vertically. Through the slow reciprocating movement of the heating wire and the foam support platform, the edges of the foam can be finely cut, correcting defects caused by a single cut, reducing manual operation, and minimizing the production of defective products.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0027] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related are omitted.

[0028] like Figure 1 As shown, this utility model embodiment provides a foam cutting device, which includes a machine tool 1, a foam support platform 2, and a cutting section 3.

[0029] The machine tool 1 is provided with a transverse lead screw 11 and two transverse guide rails 12 located on both sides of the transverse lead screw 11. Each of the two transverse guide rails 12 is provided with a sliding seat 13, so that the sliding seat 13 can move along the transverse guide rail 12.

[0030] Combination Figure 1 and Figure 2As shown, the surface of the foam support platform 2 has a limiting groove 201 in the horizontal direction. A limiting strip 21 is provided in the limiting groove 201. The top of the limiting strip 21 is higher than the surface of the platform. The limiting strip 21 can move along the limiting groove 201 and is used to abut against the edge of the foam 100 placed on the platform to limit the foam 100. Considering the soft nature of the foam 100, the limiting strip 21 is used to prevent the foam 100 from shifting laterally on the platform, thus avoiding direct compression of the foam 100. In this embodiment, the cross-section of the limiting strip 21 has an I-shaped structure, which prevents the limiting strip 21 from moving vertically in the limiting groove 201 and increases the friction when the limiting strip 21 moves laterally. The front and rear ends of the foam support platform 2 are respectively connected to two sliding seats 13. The foam support platform 2 spans and is fixed on the nut seat of the transverse screw 11. It is driven by the transverse drive motor 14 on the machine tool 1, which drives the foam support platform 2 to move back and forth on the transverse guide rail 12 along the transverse direction.

[0031] Combination Figure 1 , Figure 3 as well as Figure 4 As shown, the cutting section 3 includes a pair of guide rail posts 31, a pulley seat 32, a vertical lead screw 33, and a heating wire mounting block 34. The two guide rail posts 31 are respectively arranged opposite each other on the front and rear sides of the machine tool 1. The pulley seat 32 is fixed on the nut seat of the vertical lead screw 33 and can roll along the guide rail post 31. The heating wire mounting block 34 is locked onto the pulley seat 32 and arranged opposite each other. A heating wire 35 is installed between the two heating wire mounting blocks 34. The pulley seat 32 is driven by a lifting drive motor 36 arranged on the vertical lead screw 33, which drives the heating wire 35 to rise and fall to cut the foam 100.

[0032] Since the heating wire 35 can melt the foam 100 using heat energy, it avoids direct friction with the foam 100, reducing mechanical stress on the surface of the foam 100 and minimizing the possibility of deformation during cutting. Combined with the heating wire 35 and the foam support platform 2, which can move back and forth vertically and horizontally respectively, repeated slow back-and-forth movement during cutting allows for precise cutting of the foam 100 in different directions, reducing the production of defective products. When cutting the foam 100 in different directions on the same horizontal plane is required, the foam 100 can be rotated at a certain angle on the foam support platform 2 and then fixed by the limiting stop 21 to complete the cutting of the corresponding structure.

[0033] like Figure 3As shown, when vertically cutting foam using the aforementioned foam cutting equipment, the foam 100 is first placed on the foam support platform 2. The horizontal drive motor 14 drives the foam support platform 2 via the horizontal lead screw 11, causing the foam support platform 2 to move horizontally on the horizontal guide rail 12 via the sliding seat 13. Once the desired cutting position of the foam 100 is aligned with the predetermined lowering position of the heating wire 35, the lifting drive motor 36 drives the pulley seat 32 via the vertical lead screw 33, allowing the pulley seat 32 to repeatedly rise and fall along the guide rail column 31. The heating wire 35 moves with the heating wire mounting block 34 on the pulley seat 32, repeatedly rising and falling on the vertical plane of the desired cutting position of the foam 100, achieving precise vertical cutting. The alignment of the heating wire 35 with the desired cutting position of the foam 100 can be achieved using existing sensor technology instead of manual measurement and anchoring, further reducing manual operation.

[0034] like Figure 4 As shown, when the foam cutting equipment is used to cut the foam laterally, after the foam 100 is placed on the foam support platform 2, the lifting drive motor 36 first drives the pulley seat 32 to move along the guide rail column 31 until the heating wire 35 reaches the horizontal plane where the foam 100 is to be cut. Then, the horizontal drive motor 14 drives the foam support platform 2 through the horizontal lead screw 11, so that the foam support platform 2 moves laterally on the horizontal guide rail 12. The heating wire 35 cuts the foam 100 laterally into upper and lower parts. After the foam 100 has completely passed through the heating wire 35, the upper part of the foam 100 is removed and moved back and forth by the foam support platform 2 so that the heating wire 35 can continue to finely trim the lower part of the foam 100. After completion, the lower part of the foam 100 is removed and replaced with the upper part. The height of the horizontal plane where the heating wire 35 is located is adjusted to align with the edge of the upper part after it has been cut and finely trimmed in the same way.

[0035] The foam support platform 2 has a cutting clearance groove 202 on its surface. The cutting clearance groove 202 extends longitudinally from the front end of the foam support platform 2 to its rear end, perpendicular to the limiting groove 201. The cutting clearance groove 202 is designed to provide sufficient space for the heating wire 35 during the cutting process, preventing interference between the heating wire 35 and the platform, thus ensuring smooth cutting. Specifically, the width and depth of the cutting clearance groove 202 can be adjusted according to the size of the heating wire and cutting requirements to ensure that the heating wire 35 can move freely during cutting while avoiding damage to the platform. As a preferred embodiment, the width of the cutting clearance groove 202 can be slightly larger than the diameter of the heating wire to ensure smoothness during the cutting process.

[0036] The heating wire mounting block 34 has a beveled relief groove 340 extending vertically from its top to its bottom. When it is necessary to form a beveled surface on the foam 100, the heating wire mounting blocks 34 on both sides of the machine tool 1 can be moved to different height planes so that the heating wire 35 is arranged obliquely. The groove of the beveled relief groove 340 makes way for the heating wire 35, avoiding direct interference between the heating wire 35 and the heating wire mounting block 34. The heating wire mounting block 34 needs to be connected to an external wire to supply power to the heating wire 35 to avoid damage to these structures caused by the heating wire 35.

[0037] The design of the beveled relief groove 340 allows the heating wire 35 to be positioned more flexibly during the cutting process.

[0038] A scale is provided on the edge of the foam support platform 2. The scale allows the operator to accurately measure the size of the foam, thereby achieving more precise positioning and adjustment during the cutting process, avoiding the inconvenience of frequently using external measuring tools, and improving cutting efficiency.

[0039] Furthermore, the surface of the foam support platform 2 is covered with an anti-slip polyurethane layer. The anti-slip polyurethane layer can be fixed to the platform surface by coating, pasting, or hot pressing, and its thickness can be adjusted according to actual needs. The anti-slip polyurethane layer has a high coefficient of friction, effectively preventing the foam from sliding or shifting during the cutting process, thereby improving cutting accuracy and stability. As a preferred embodiment, the surface of the anti-slip polyurethane layer can be designed with an uneven texture to further enhance its anti-slip effect. In addition, the anti-slip polyurethane layer also has a certain degree of elasticity, which can buffer the impact on the foam 100 during the cutting process to a certain extent, reducing deformation or damage to the foam 100 caused by cutting.

[0040] In this embodiment, the lateral drive motor 14 and the lifting drive motor 36 are respectively connected to a control console via signals, so as to control the start and stop of the lateral drive motor 14 and the lifting drive motor 36 through the control console, thereby realizing automated operation.

[0041] Specifically, the front and rear sides of the machine tool 1 are respectively provided with support column 15 in the same longitudinal direction, and the two guide rail columns 31 are correspondingly locked to the support column 15 for opposite fixation, which facilitates installation and ensures that the pulley seat 32 and the heating wire mounting block 34 on the guide rail column 31 are symmetrically arranged.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0043] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
