It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0029] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] See also Figure 1 , Figure 2 as well as Figure 3 , an embodiment of the utility model provides a cutting device 100 for a PVC wall panel.

[0031] like Figure 1 , Figure 2 As shown, the PVC wallboard cutting device 100 includes a cutting component 110, a limiting component and a carrier 130;

[0032] The cutting assembly 110 is mounted and fixed on the carrier 130 and is used for cutting PVC wallboards;

[0033] The limiting assembly includes a movable limiting member, a first fixing member 122, a first screw rod 123 and a first driving member 124;

[0034] The movable limiting member includes a limiting portion 1211 and a guiding portion 1212 fixedly connected to the limiting portion 1211, the carrier 130 has a guiding hole 131, the limiting portion 1211 is located above the carrier 130 and is parallel to the cutting direction of the cutting assembly 110; the guiding portion 1212 passes through the guiding hole 131 and is located below the carrier 130, the first fixing member 122 is disposed below the carrier 130 and is fixedly connected to the carrier 130, the first screw rod 123 is threadedly engaged with the guiding portion 1212; one end of the first screw rod 123 passes through the first fixing member 122, and forms a first rotating pair with the first fixing member 122, the first driving member 124 is connected to the first screw rod 123, and can drive the first screw rod 123 to rotate.

[0035] It can be understood that the technical solution of the utility model is to set a limit assembly, which includes a movable limit member, a first fixing member 122, a first screw rod 123 and a first driving member 124; when the user drives the first driving member 124 to work, the first screw rod 123 rotates, and the first screw rod 123 rotates and drives the guide portion 1212 threadedly matched with it to move in the extension direction of the first screw rod 123, and the guide portion 1212 moves, thereby driving the limit portion 1211 located on the carrier 130 to move, so that the limit portion 1211 is close to or away from the cutting assembly 110, and the threaded matching has an axial self-locking function, and the driving member 124 is provided with a plurality of movable limit members, and the plurality of movable limit members 1211 are ... When the first driving member 124 stops working, the position of the limiting part 1211 and the cutting assembly 110 can be relatively fixed. When the user determines the cutting width of the PVC wallboard, the distance between the limiting part 1211 and the cutting assembly 110 is adjusted by driving the first driving member 124, the cutting assembly 110 is started, the PVC wallboard is placed on the carrier 130, and the PVC wallboard is pushed toward the cutting direction of the cutting assembly 110 close to the limiting part 1211 to complete the cutting. Therefore, the technical solution of the utility model only needs to pre-adjust the distance between the limiting part 1211 and the cutting assembly 110 before use to perform cutting, thereby improving the cutting efficiency of the PVC wallboard. The PVC wallboard is pushed toward the cutting direction of the cutting assembly 110 close to the limiting part 1211 to perform semi-automatic mechanical cutting, thereby improving the cutting quality of the PVC wallboard.

[0036] See also Figure 2In one embodiment of the present invention, the PVC wall panel cutting device 100 further includes a second fixing member 125, which is disposed below the carrier 130, located on the side of the guide portion 1212 away from the first fixing member 122, and is rotatably connected to the other end of the first screw rod 123 to form a second rotation pair. It can be understood that the first rotation pair and the second rotation pair are formed at both ends of the first screw rod 123, which improves the stability of the first screw rod 123 driving the guide portion 1212 to move.

[0037] Please continue reading Figure 2 In a preferred embodiment, the limiting assembly also includes a second screw rod 126, which is threadedly matched with the guide portion 1212, and one end of the second screw rod 126 passes through the first fixing member 122 to form a third rotation pair with the first fixing member 122; the first driving member 124 can drive the first screw rod 123 and the second screw rod 126 to rotate synchronously.

[0038] Further, the first driving member 124 includes a synchronous belt 1241, a first synchronous wheel 1242, a second synchronous wheel 1243 and a rocker 1244; the first synchronous wheel 1242 is fixedly connected to the first screw rod 123, the second synchronous wheel 1243 is fixedly connected to the second screw rod 126, the synchronous belt 1241 is circled on the first synchronous wheel 1242 and the second synchronous wheel 1243, and drives the first synchronous wheel 1242 and the second synchronous wheel 1243 to rotate synchronously, the rocker 1244 is connected to the first screw rod 123 through the first synchronous wheel 1242, and rotating the rocker 1244 can drive the first synchronous wheel 1242 and the second synchronous wheel 1243 to rotate synchronously through the synchronous belt 1241.

[0039] It is understandable that if Figure 2 As shown, the rocker 1244 is roughly arranged in a Z shape, one end of the rocker 1244 is fixed to the first screw rod 123 in the rotation direction of the first screw rod 123, and the other end of the rocker 1244 is used for hand-held rotation.

[0040] Optionally, the first synchronous wheel 1242 is a gear, and the synchronous belt 1241 is a toothed belt.

[0041] Optionally, the second synchronous wheel 1243 is a pulley, and the synchronous belt 1241 is a V-belt.

[0042] Furthermore, a protrusion (not shown) is provided on the outer periphery of the synchronous belt 1241, and a trigger switch (not shown) is provided on the carrier 130 corresponding to the protrusion. Under the transmission of the synchronous belt 1241, the protrusion passes through the trigger switch in sequence, and the limit portion moves Xmm, where the value of X is an arbitrary real number.

[0043] Preferably, X is a number whose absolute value is less than or equal to 10, for example: 1 or 2 or 5 or 10.

[0044] It is understandable that a protrusion is set on the synchronous belt 1241, and the trigger switch can record the number of times the protrusion passes, and the displacement of the limit part can be indirectly obtained. The setting of the protrusion and the trigger switch can ensure the long-term stable acquisition of displacement parameters, and the setting of the protrusion and the trigger switch is also very convenient for maintenance. The maintenance personnel only need to determine whether the protrusion is damaged or the trigger switch is damaged, and replace or repair the corresponding device. Specifically, the judgment of whether the two are damaged can be either one or the other, and the judgment of the protrusion only needs to be observed.

[0045] It can also be understood that a plurality of protrusions are arranged at equal intervals on the outer circumference of the synchronous belt 1241 , and the arrangement of the plurality of protrusions can improve the displacement accuracy of the limiting portion 1211 .

[0046] Furthermore, if Figure 1 As shown, the carrier 130 further includes a display 133, and the display 133 is connected to the trigger switch signal.

[0047] It is understood that the display 133 is configured to display the relative displacement distance of the limiter 1211 obtained by triggering the switch. Optionally, the display 133 is provided with a calibration key. It is understood that each time the distance between the limiter 1211 and the cutting assembly 110 is adjusted, the distance between the limiter 1211 and the cutting assembly 110 is restored to the maximum, and calibration on the display 133 is performed. Preferably, the calibration value on the display 133 is displayed as the maximum distance between the limiter 1211 and the cutting assembly 110, and the distance displayed on the display 133 is the maximum distance between the limiter 1211 and the cutting assembly 110 minus the moving distance of the limiter 1211.

[0048] It is understandable that the operator can complete the adjustment of the limit portion based on the consistency between the displayed distance on the display 133 and the target cutting width.

[0049] In a preferred embodiment, the carrier 130 is further marked with scale lines, the zero scale line of the scale lines is close to the cutting groove 132, and the scale lines are accumulated in a direction close to the limiting portion.

[0050] It is understandable that the operator can quickly locate the target position of the limit portion according to the scale on the scale line.

[0051] It should also be noted that the scale lines are relatively easy to wear or damage, and are thus an alternative embodiment of the present invention.

[0052] like Figure 3 As shown, in another embodiment of the present utility model, the position limiting assembly further includes a third fixing member 127 and a first guide column 128, the third fixing member 127 is arranged below the carrier 130, and is located on the side of the guide portion 1212 away from the first fixing member 122, the first guide column 128 is arranged parallel to the first screw rod 123, the first guide column 128 penetrates the guide portion 1212 and slides with the guide portion 1212, one end of the first guide column 128 is installed on the first fixing member 122, and the other end is installed on the second fixing member 125. Further, the position limiting assembly further includes a second guide column 129, the second guide column 129 and the first guide column 128 are located on both sides of the first screw rod 123, and the second guide column 129 is parallel to the first guide column 128.

[0053] It is understandable that in the above embodiment, the first guide column 128 is connected to the guide portion 1212, thereby preventing the limit portion 1211 from tilting relative to the cutting assembly, thereby improving the cutting quality of the PVC wallboard. The first guide column 128 and the second guide column 129 both guide the movable limiter, thereby improving the stability of the movable limiter moving along the guide hole 131.

[0054] See also Figure 1 In a preferred embodiment, the cutting device 100 for the PVC wallboard further includes a fourth fixing member 140 , which is disposed on the platform 130 , fixedly connected to the platform 130 , and parallel to the limiting portion 1211 .

[0055] It is understandable that the fourth fixing member 140 can be used in conjunction with the limiting portion 1211 , and when the PVC wallboard needs to be cut in the width direction, the PVC wallboard can be placed on the upper surface of the limiting portion 1211 and the first fixing member 122 .

[0056] Continue reading Figure 1 The carrier 130 further has a cutting groove 132 , and the cutting groove 132 is arranged corresponding to the cutting assembly 110 , and the extension direction of the cutting groove 132 is flush with the extension direction of the limiting portion 1211 .

[0057] It is understandable that the cutting groove 132 can expand the cutting space of the cutting assembly 110 and avoid damage to the carrier 130. It is also understandable that the cutting groove 132 is set corresponding to the cutting assembly 110, and the user can accurately determine the pre-cutting size by obtaining the size from the cutting groove 132 to the limit portion 1211.

[0058] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
