The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0036] This embodiment provides a cutting device, as Figures 1 - 6 shown, which includes a platform unit 1, a positioning unit 2, a pressing unit 3, and a cutting unit 4. The platform unit 1 is used to support the workpiece to be cut 5. The positioning unit 2, the pressing unit 3, and the cutting unit 4 are all arranged on the platform unit 1. The positioning unit 2 is used to position the workpiece to be cut 5; the pressing unit 3 is used to press the workpiece to be cut 5 onto the platform unit 1; the cutting unit 4 includes a bracket 41 and a cutter 42. The bracket 41 is fixed to the platform unit 1, and the cutter 42 is slidably connected to the bracket 41, and the cutter 42 slides along a preset trajectory to cut the workpiece to be cut 5.

[0037] The process steps of using the cutting device to cut a workpiece to be cut 5 such as thermal insulation cotton include: placing the workpiece to be cut 5 on the platform unit 1, the positioning unit 2 positions the workpiece to be cut 5, the pressing unit 3 presses the workpiece to be cut 5, and the cutter 42 slides along a preset trajectory to cut the workpiece to be cut 5. There is no need to cut along the edge of a steel ruler. Instead, the cutter 42 slides along a preset trajectory, thus avoiding cutting the hand used to press the steel ruler, reducing the production safety risk, being simple to operate, and improving the cutting quality. Since the cutter 42, the pressing unit 3, and the positioning unit 2 are all arranged at determined positions on the platform unit 1, it avoids taking and placing the blade and the steel ruler back and forth in the traditional structure, is convenient to operate, saves the operation time and simplifies the operation steps, thereby improving the cutting operation efficiency.

[0038] In the first embodiment, as Figure 1As shown, a positioning unit 2, a cutting unit 4 and a pressing unit 3 are provided on the platform unit 1. The positioning unit 2 includes a fixed positioning stop bar 21. There is one cutting unit 4, and the cutting unit 4 and the fixed positioning stop bar 21 are perpendicularly arranged. When the workpiece to be cut 5 is arranged on the platform unit 1, one end of the workpiece to be cut 5 in the first direction abuts against the fixed positioning stop bar 21, and the pressing unit 3 presses on the workpiece to be cut 5 along the second direction. The pressing and positioning of the workpiece to be cut 5 are realized through the pressing unit 3 and the fixed positioning stop bar 21. Then, cutting is performed along the first direction by a cutter 42 provided on one side close to the pressing unit 3.

[0039] In one embodiment, the positioning unit 2 further includes a rotating positioning stop bar 22, and the rotating positioning stop bar 22 can be rotated to be collinear with the fixed positioning stop bar 21. The length of the fixed positioning stop bar 21 can be extended through the rotating positioning stop bar 22. When the size of the workpiece to be cut 5 is large, by rotating the rotating positioning stop bar 22 in one direction, the rotating positioning stop bar 22 is made collinear with the fixed positioning stop bar 21 to improve the positioning reliability. And when the cutting equipment is not in use, the rotating positioning stop bar 22 is rotated in the other direction, so that the rotating positioning bar can be retracted to reduce the occupied space of the equipment.

[0040] In the second embodiment, as Figure 2 and Figure 3As shown in the figure, two positioning units 2, two cutting units 4 and two pressing units 3 are provided on the platform unit 1. Each positioning unit 2 includes a fixed positioning bar 21. A cutting unit 4, a fixed positioning bar 21 and a pressing unit 3 are arranged opposite to each other, and the other cutting unit 4, the other fixed positioning bar 21 and the other pressing unit 3 are arranged opposite to each other. Generally, the shape of the workpiece to be cut, such as the insulation cotton 5, is rectangular. The two fixed positioning bars 21 are vertically arranged, that is, one fixed positioning bar 21 is arranged along the Y direction, and the other fixed positioning bar 21 is arranged along the X direction. The two are perpendicular to each other and form an L shape. The workpiece to be cut 5 can be positioned in two directions, the X direction and the Y direction, through the two L-shaped fixed positioning bars 21. The two cutting units 4 are respectively used for cutting in the X direction and the Y direction, avoiding the need to rotate the workpiece to be cut 5 after cutting in one direction, and then using the same positioning unit 2 and cutting unit 4 for positioning and cutting. In the present solution, only the workpiece to be cut 5 needs to be translated to another positioning unit 2, and the other cutting unit 4 is used to complete the cutting of the workpiece to be cut 5, improving the cutting operation efficiency. When cutting the workpiece to be cut 5 along the X direction, the cutting unit 4 perpendicular to one fixed positioning bar 21 is used for cutting, and the sliding track of the cutting tool 42 is along the X direction. When cutting the workpiece to be cut 5 along the Y direction, the cutting unit 4 perpendicular to the other fixed positioning bar 21 is used for cutting, and the sliding track of the cutting tool 42 is along the Y direction. By setting two cutting units 4, linear cutting in two directions is realized, with a simple structure and improved cutting operation efficiency.

[0041] In an embodiment, each positioning unit 2 further includes a rotating positioning bar 22. One rotating positioning bar 22 can rotate to be collinear with one fixed positioning bar 21, and the other rotating positioning bar 22 can rotate to be collinear with the other fixed positioning bar 21. The length of the fixed positioning bar 21 can be extended through the rotating positioning bar 22. When the size of the workpiece to be cut 5 is large, such as when the length along the Y direction is long, by rotating one rotating positioning bar 22 to make the rotating positioning bar 22 collinear with the fixed positioning bar 21, the positioning reliability in the Y direction is improved. When the length along the X direction is long, by rotating the other rotating positioning bar 22 to make the rotating positioning bar 22 rotate to be collinear with the fixed positioning bar 21, the positioning reliability in the X direction is improved.

[0042] In an embodiment, one end of the rotating positioning bar 22 is fixed, and the other end can rotate 90 degrees along the fixed end, which can position the insulation cotton in the X direction or the Y direction; and when the cutting device is not in use, the rotating positioning bar 22 can be rotated to retract the rotating positioning bar, reducing the occupied space of the device in the X direction or the Y direction.

[0043] In the first embodiment, by providing a positioning unit 2, a cutting unit 4 and a pressing unit 3, cutting of the workpiece 5 to be cut is achieved in one direction. In the second embodiment, by providing two positioning units 2, two cutting units 4 and two pressing units 3, cutting of the workpiece 5 to be cut can be achieved in the X and Y directions respectively.

[0044] The structure in the second embodiment is basically the same as that in the first embodiment, and the dimensions may be different. The only difference between the two lies in the number of the cutting unit 4, the pressing unit 3 and the positioning unit 2 provided, which can be set according to actual needs. The same parts in the first embodiment and the second embodiment will not be described again.

[0045] As Figure 2 and Figure 3 shown, a scale 26 is provided on the fixed positioning bar 21 arranged in the Y direction, so as to measure and mark when cutting the workpiece 5 to be cut. Further, scales are provided on the fixed positioning bars 21 in the X direction or / and Y direction, and scales (not shown in the figure) are fixed above both of the two rotating positioning bars 22. Further, scales (not shown in the figure) are respectively provided on the fixed positioning bar 21 and the rotating positioning bar 22, and the 0 graduation lines of the two scales are arranged facing each other, which is convenient for measuring the cutting size of the workpiece 5 to be cut.

[0046] Further, as Figure 2 shown, the rotating positioning bar 22 is limited at two extreme positions by providing a limit block 25.

[0047] In one embodiment, as Figures 1 - 4 shown, the bracket 41 is in a gate shape. The gate-shaped structure facilitates the workpiece 5 to pass through below the gate shape of the bracket 41. At the same time, when the equipment is not in use, the first rotating positioning bar 22 is arranged below one bracket 41, and the rotating positioning bar 22 is arranged below the other bracket 41, saving space.

[0048] Further, the thicknesses of the current thermal insulation cotton are respectively 25mm, 30mm, 40mm and 50mm. Therefore, in this embodiment, the gap between the gate-shaped bracket 41 and the working surface of the platform unit 1 is designed to be 60mm, so as to facilitate the placement of the thermal insulation cotton during operation.

[0049] In one embodiment, the cutting unit 4 further includes a guide rail 43 provided on the bracket 41 and a slider 44 slidably connected to the guide rail 43. The cutter 42 is provided on the slider 44, and the cutter 42 is slidably connected to the guide rail 43 through the slider 44. In this embodiment, the cutter 42 cuts along the X direction or the Y direction, and the guide rail 43 is arranged along the X direction or the Y direction.

[0050] In one embodiment, the cutting unit 4 further includes a handle 45 provided on the slider 44. One can hold the handle 45 to push the cutting tool 42 to achieve manual cutting. In other embodiments, a power structure can also be provided to achieve automatic cutting, which is set according to the actual situation and is not limited.

[0051] In one embodiment, as Figures 3 - 5 shown, the cutting tool 42 is provided on one side of the bracket 41 facing the pressing unit 3, further preventing the workpiece 5 to be cut from shifting during the cutting process and improving the cutting reliability. In one embodiment, there are two pressing units 3.

[0052] In one embodiment, the pressing unit 3 includes a rotating seat 32 and a pressing strip 33. The rotating seat 32 is fixed to the platform unit 1. One end of the pressing strip 33 is rotatably connected to the rotating seat 32, and the workpiece 5 to be cut is clamped between the pressing strip 33 and the platform unit 1. The pressing strip 33 can rotate to press or release the workpiece 5 to be cut. During operation, one hand can press the pressing strip 33, and the other hand can hold the handle 45 to achieve cutting. Then, release the pressing strip 33 and return the cutting tool 42 to the initial position.

[0053] In one embodiment, the pressing unit 3 further includes a movable seat 31. One end of the movable seat 31 passes through and is movably connected to the platform unit 1. The movable seat 31 and the platform unit 1 are limited in position to make it have a relatively stable position, improving the structural stability. Further, the other end of the pressing strip 33 is detachably connected to the movable seat 31 and can adjust its position on the movable seat 31, so as to be applicable to pressing workpieces 5 to be cut with different thicknesses.

[0054] Further, considering that the current thicknesses of the thermal insulation cotton are 25mm, 30mm, 40mm, and 50mm respectively, in this embodiment, the gap between the pressing strip 33 and the working surface is designed to be 40mm. Since the pressing strip 33 can rotate, when the thickness of the thermal insulation cotton is less than 40mm, the other end of the pressing strip 33 rotates below the plane, and when the thickness of the thermal insulation cotton is greater than 40mm, the other end of the pressing strip 33 rotates above the plane, thus improving the applicability to cutting different thermal insulation cottons.

[0055] In one embodiment, the pressing strip 33 and the cutting tool 42 are arranged at intervals. When manually pressing the pressing strip 33, it is ensured that there is enough space between the hand and the cutting tool 42 to prevent cutting the hand and improve safety.

[0056] In one embodiment, as Figure 1As shown, the platform unit 1 includes a working platform 11 for supporting the workpiece 5 to be cut. The working platform 11 is provided with a cutting groove 111 extending in the first direction, that is, the cutting groove 111 extends along the preset track direction. Specifically, the width of the cutting groove 111 can accommodate the head of the cutter 42, so that the cutter 42 extends into the cutting groove 111. The workpiece 5 such as thermal insulation cotton is covered with a layer of aluminum foil. If there is no cutting groove 111 and cutting is directly performed on the upper surface of the platform unit 1, it is often not easy to cut through this layer of aluminum foil. By designing this cutting groove 111, the thermal insulation cotton can be cut through during cutting, improving the cutting reliability.

[0057] In one embodiment, as Figure 3 and Figure 4 shown, the working platform 11 is provided with two cutting grooves 111. The two cutting grooves 111 are arranged at an angle, specifically 90°, and the two cutting grooves 111 do not cross, ensuring the strength of the entire platform unit 1. In one embodiment, one of the two cutting grooves 111 has a longer length, which can cut longer thermal insulation cotton and can reduce the size of the working platform 11 of the platform unit 1.

[0058] In one embodiment, as Figure 1 and Figure 4 shown, the cutting groove 111 is provided with an extension 1111. When the workpiece 5 is located on the platform unit 1, the extension 1111 is arranged on one side of the workpiece 5, and the cutter 42 can slide to the extension 1111. The cutter 42 is first in the initial position, that is, the cutter 42 is at the top of the slide rail, so as to ensure cutting from one side of the workpiece 5.

[0059] In one embodiment, as Figure 6 shown, the platform unit 1 further includes a reinforcing rib 12. The reinforcing rib 12 is arranged below the cutting groove 111. The reinforcing rib 12 is provided with a receiving groove 121 along the length direction. The cutting head of the cutter 42 is received in the receiving groove 121. Through the design of the reinforcing rib 12, it is ensured that the thermal insulation cotton can be cut through, and the cutter 42 is prevented from penetrating from the other end and hurting the operator. Specifically, the reinforcing rib 12 is welded below the cutting groove 111 to increase the strength of the platform unit 1. Specifically, it is a V-shaped reinforcing rib 12, and the V-groove of the V-shaped reinforcing rib 12 is the receiving groove 121 that can accommodate the head of the cutter 42.

[0060] Specifically, the cutter 42 is a stainless steel blade, etc., which is not limited.

[0061] Specifically, as Figure 3 shown, the platform unit 1 further includes a frame 13 for supporting the working platform.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here.
