A foam cutting machine Technical Field

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

[0002] A foam cutting machine is a device used to process materials such as foam and sponge in the chemical industry. It mainly utilizes the heating of resistance wires to thermally cut the foam at high temperatures.

[0003] Traditional foam cutters are large, so they must be disassembled into multiple parts for transport to save space, and then reassembled by the customer. Furthermore, users need to disassemble them again for storage, which is inconvenient and affects the user experience. In addition, existing foam cutters are not size-adjustable, preventing users from flexibly adjusting them to their needs. Therefore, there is an urgent need for a new type of foam cutter to solve the problems of difficult storage and inability to adjust the size of existing foam cutters. Summary of the Invention

[0004] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a foam cutting machine that can change its volume by rotating, folding or stretching, so as to facilitate user storage and adjustment.

The main support plate includes a front and a back side arranged opposite to each other. A gantry is rotatably connected to the front side, and an electric heating wire is provided on the gantry. A support assembly is connected to the back side, and the folding modules are movably connected to the back side. The folding module includes a threaded post, a limiting post, a connecting plate, and a secondary support plate. The threaded post and the limiting post protrude from the back side. One end of the connecting plate is connected to the secondary support plate, and the connecting plate is provided with a connecting groove. The folding module has a rotating state and a sliding state. In the rotating state, the threaded post is inserted into the connecting groove. In the sliding state, both the threaded post and the limiting post are inserted into the connecting groove. The folding module also includes an adjusting nut that cooperates with the threaded post for adjusting the connecting plate.

[0006] Furthermore, the gantry includes a main beam, a support arm, and an arc-shaped dial. The arc-shaped dial is fixed to the front of the main support plate. Both ends of the main beam are connected to the corresponding support arms. The support arms are rotatably connected to the arc-shaped dial. A first central hole is provided on the arc-shaped dial. A first positioning hole is provided at one end of the support arm. The first central hole and the first positioning hole are connected by bolts and nuts.

[0007] Furthermore, the circular dial has a first circular groove centered on the first central hole, and the circular dial has a first angle scale that mates with the first circular groove. The support arm has a second positioning hole, and the first circular groove and the second positioning hole are connected by bolts and nuts.

[0008] Furthermore, the support assembly includes a first leg, a second leg, a third leg, a beam frame, and a support bar. The beam frame is attached to the back of the main support plate. The first leg is rotatably connected to the beam frame. One end of the support bar is rotatably connected to the back of the main support plate. The support bar has several equally spaced slots. The first leg has a latch that engages with the slots. The second leg and the third leg are connected to the back of the main support plate and are symmetrically arranged on both sides of the beam frame.

[0009] Furthermore, the first support leg includes a first outer tube and a first inner tube, the first outer tube being sleeved on the first inner tube and capable of sliding relative to it, and a first adjusting bolt for adjusting the movement of the first outer tube relative to the first inner tube is inserted on the first outer tube; the second support leg includes a second outer tube and a second inner tube, the second outer tube being sleeved on the second inner tube and capable of sliding relative to it, and a second adjusting bolt for adjusting the movement of the second outer tube relative to the second inner tube is inserted on the second outer tube; the third support leg includes a third outer tube and a third inner tube, the third outer tube being sleeved on the third inner tube and capable of sliding relative to it, and a first adjusting bolt for adjusting the movement of the third outer tube relative to the third inner tube is inserted on the third outer tube.

[0010] Furthermore, a positioning ruler is rotatably connected to the front side of the main support plate. A second center hole is provided on the front side, and a third positioning hole is provided on the positioning ruler. The second center hole and the third positioning hole are connected by bolts and nuts. A second arc groove is provided on the front side of the main support plate with the second center hole as the center. A second angle scale that mates with the second arc groove is provided on the front side of the main support plate. A fourth positioning hole is provided on the positioning ruler.

[0014] Furthermore, the length of the threaded post is greater than that of the limiting post.

[0015] Compared with the prior art, the advantages of this utility model are as follows: In the rotating state of the folding module, by inserting only the threaded post into the connecting groove, the connecting plate can rotate and slide around the threaded post, allowing the user to rotate and fold the folding module, stacking the main support plate and the secondary support plate for easy storage. This also eliminates the need for merchants to disassemble and transport the product, and users can use it immediately upon receipt without assembly, enhancing the convenience of use. In the sliding state of the folding module, by inserting both the threaded post and the limiting post into the connecting groove, they act as guides, allowing the connecting plate to slide along the length of the connecting groove. This allows users to extend or shorten the folding module relative to the main support plate, facilitating size adjustments to suit different work needs and saving space, thus enhancing practicality. The adjustable nut allows users to either tighten it to secure the connecting plate (the folding module) or loosen it to adjust the fit between the connecting groove, threaded post, and limiting post, enabling the folding module to switch between rotating and sliding states. The gantry, rotatably connected to the front of the main support plate, allows for easy folding and stacking with the main support plate, facilitating storage. Attached Figure Description
