At the same time, the plane of the edge skin is horizontally supported on the clamp, and after the edge skin is clamped, the horizontal space is large, which is not conducive to the arrangement of multiple groups of edge skins.

[0040] In order to better explain the present invention, so as to facilitate understanding, the following Figure 1-Figure 7 , the present invention is described in detail through specific implementation methods. Figure 1 The orientation is used as a reference.

[0041] Embodiment 1:

[0042] Reference Figure 1-Figure 7An embodiment of the present invention provides a skin edge cutting machine, including a clamping device 100 and a cutting head 200, a cutting area is formed below the cutting head 200, and the clamping device 100 can slide horizontally and switch between a cutting station facing the cutting area and a loading and unloading station that leaves the cutting area; the clamping device 100 includes a clamping unit 1, and the clamping unit 1 includes a base 11, a support plate 12 and a pressing plate 13; the support plate 12 is fixedly connected to the base 11, and the pressing plate 13 is hinged to the base 11 along a first horizontal direction, and a clamping area C extending along the first horizontal direction and having a skin edge inlet and outlet formed above is formed between the support plate 12 and the pressing plate 13; the projection of the clamping area C along the first horizontal direction is inclined relative to the vertical direction, so that the skin edge remains inclined in the clamping area C. The support plate 12 can support the side skin in a directional manner along the first horizontal direction along the length direction of the side skin and with the arc surface facing outward. The pressing plate 13 can swing and switch between a pressing position for pressing the arc surface of the side skin on the support plate 12, and a loosened position for detaching from the support plate 12 and allowing it to enter and exit the side skin inlet and outlet.

[0043] A cutting area is provided below the cutting head 200 for cutting the edge skin. The clamping device 100 can slide and switch horizontally between the cutting station and the loading and unloading station to cooperate with the cutting head 200 to cut the edge skin and load and unload the material.

[0044] The clamping unit 1 includes a base 11, a support plate 12 and a pressure plate 13. The base 11 serves as a supporting structure of the clamping unit 1, and is fixedly connected to the support plate 12 and the hinged pressure plate 13. The support plate 12 is fixedly connected to the base 11 and is used to support the edge skin to be cut off. The lower part of the pressure plate 13 is hinged to the base 11 along a first horizontal direction, and can be swung and switched between a clamping position and a loose position.

[0045] When in the tightening position, the pressing plate 13 is close to the supporting plate 12 to clamp the edge skin; when in the loosening position, the pressing plate 13 is away from the supporting plate 12 to release the edge skin. The clamping area C is formed between the supporting plate 12 and the pressing plate 13, extending along the first horizontal direction, and the edge skin inlet and outlet are arranged on the top to facilitate the edge skin to be loaded into the clamping area C and removed from the clamping area C.

[0046] Compared with the prior art, the clamping unit 1 included in the clamping device 100 in this embodiment can vertically load the edge skin into the clamping area C, thereby greatly improving the convenience and efficiency of clamping the edge skin. During the cutting process of the edge skin, the vertical downward cutting force can be effectively borne by the support plate 12, and the pressing plate 13 presses the edge skin to stabilize the edge skin and does not bear the cutting force, thereby improving the stability of the edge skin during the cutting process.

[0047] The pressing plate 13 that swings and presses the edge skin can adapt to edge skins of different radii and thicknesses, thereby greatly improving the flexibility of use of the clamping unit 1 and improving the adaptability of the edge skin cutting machine to the size of the edge skin.

[0048] Since the clamping area C extends obliquely, the edge skin can remain inclined when being clamped. In this way, the contact area between the edge skin and the cutting head 200 can be reduced when the edge skin cooperates with the cutting head 200, thereby increasing the cutting stress and reducing the probability of wire breakage during the cutting process, which is beneficial to improving the cutting efficiency and cutting effect.

[0049] At the same time, precisely because the edge skin remains tilted when being clamped, it occupies less lateral space, thereby providing a structural basis for arranging more clamping units 1 and cutting heads 200, which is beneficial to further improve the cutting efficiency of the edge skin cutting machine for the edge skin.

[0050] The surface of the support plate 12 facing the pressure plate 13 forms an intersecting side supporting surface A and a bottom supporting surface B. The side supporting surface A is suitable for fitting with the plane of the side skin and extending obliquely, and the bottom supporting surface B is suitable for supporting the edge of the side skin.

[0051] Specifically, the side supporting surface A and the bottom supporting surface B can be set to be perpendicular to each other, and the angle of the side supporting surface A relative to the vertical direction is b, where 0°<b<45°, to ensure that the side supporting surface A has sufficient supporting capacity while reducing the lateral space occupied by the side skin when it is clamped.

[0052] In this embodiment, the clamping device 100 includes a plurality of clamping units 1 distributed along a second horizontal direction, and the bases 11 of adjacent clamping units 1 are connected as a whole; a vertically extending make way channel H suitable for making way for the cutting section is formed between adjacent support plates 12 and between adjacent pressure plates 13; the second horizontal direction is perpendicular to the first horizontal direction.

[0053] The clamping units 1 are distributed along the second horizontal direction, that is, the clamping units 1 are parallel to each other and the intervals between them are uniform, thereby ensuring the stability and consistency of the entire clamping device 100 when clamping the edge skin. The bases 11 of adjacent clamping units 1 are connected as a whole. This design not only increases the overall structural strength of the clamping device 100, but also enables multiple clamping units 1 to be moved and positioned as a whole, thereby improving the flexibility and adaptability of the clamping device 100.

[0054] The purpose of the clearance channel H is to provide enough space for the cutting section so that it will not be blocked by the clamping device 100 when cutting the edge skin. The design of the clearance channel H ensures that the cutting section can smoothly pass through the clamping device 100 and accurately cut the edge skin. At the same time, since the clearance channel H extends vertically, it can also serve as an excretion channel, which can effectively prevent the debris and waste generated during the cutting process from accumulating on the clamping device 100, thereby keeping the clamping device 100 clean and operating efficiently.

[0055] In this embodiment, the edge skin cutting machine also includes a base 500, a slide 400, a first sliding drive and a positioning device 600. The slide 400 is slidably connected to the base 500 in a transverse direction. The first sliding drive is supported on the base 500 and is drivingly connected to the slide 400. The clamping device 100 is fixedly connected to the slide 400. The positioning device 600 is supported on the base 500 in a lifting manner. The positioning device 600 can be switched between a lowered position and a supporting position. In the lowered position, the positioning device 600 Located at the lower part of the slide 400 and the slide 400 is supported on the base 500; in the supporting position, the positioning device 600 supports the slide 400 and can gradually approach the cutting head 200 to complete the cutting operation; the slide 400 and the clamping device 100 are arranged as two groups corresponding to each other; the loading and unloading stations are arranged as two groups located on both sides of the cutting station; when one slide 400 is in the cutting station, the other slide 400 is in any loading and unloading station; the slide 400 is slidably connected to the base 500 along the second horizontal direction.

[0056] The slide 400 is designed to be connected to the base 500 in a transverse sliding manner, so as to realize the switching of the clamping device 100 between the cutting station and the loading and unloading station. Specifically, a track is arranged on the base 500, and a slider matching the track is arranged on the slide 400. The slide 400 is driven to slide by the first sliding driving member, and cooperates with the control system to realize the automatic movement of the clamping device 100.

[0057] The positioning device 600 can be raised or lowered as needed to change its position relative to the slide 400 and the cutting section. During the cutting process of the edge skin, the positioning device 600 supports the slide bar to move upward, while the cutting head 200 remains fixed, which is conducive to ensuring the position accuracy of the cutting head 200 and further improving the cutting accuracy.

[0058] The slides 400 and the clamping devices 100 are arranged in two groups corresponding to each other, and the loading and unloading stations are arranged in two groups located on both sides of the cutting station. This arrangement allows one slide 400 to be in the cutting station for cutting, while the other slide 400 can be moved to the loading and unloading station for loading or unloading the edge skin, thereby improving the production efficiency and flexibility of the edge skin cutting machine.

[0059] The slide 400 is designed to be slidably connected to the base 500 along a second horizontal direction, which is beneficial to the arrangement of the edge skin cutting mechanism components. At the same time, this sliding direction is consistent with the arrangement direction of the clamping unit 1 and is perpendicular to the extension direction of the edge skin after clamping. Therefore, when the edge skin slides with the clamping device 100, its inertia will act vertically on the clamping unit 1, thereby ensuring the stability of the edge skin during movement.

[0060] In this embodiment, the edge skin cutting machine also includes a column 800 and a lifting drive member 900. The column 800 is fixedly connected to the base 500. The lifting drive member 900 includes a first rotating drive member 901 and a lead screw 902 that are driven and connected to each other. The first rotating drive member 901 is fixedly connected to the column 800, and the lead screw 902 is vertically rotatably connected to the column 800 and / or the base 500; the positioning device 600 includes a lifting plate 601 and a positioning pin 602 fixedly connected to the lifting plate 601, and the positioning pin 602 can be vertically inserted into the positioning hole on the slide 400. The lifting plate 601 is vertically slidably connected to the column 800 and is threadedly matched with the lead screw 902; the column 800, the lifting drive member 900 and the positioning device 600 are arranged as two corresponding groups, and are respectively located on both sides of the base 500.

[0061] The lifting drive 900 can drive the positioning device 600 to rise and fall, thereby ensuring the stability of the slide 400 during the lifting and falling. The columns 800 and the lifting drive 900 are both arranged in two groups located on both sides of the base 500, so that the balance of the lifting drive 900 driving the positioning device 600 to rise and fall can be improved, thereby further improving the stability of the slide 400 during the lifting and falling.

[0062] When the positioning pin 602 is matched with the positioning hole, the position of the slide 400 relative to the base 500 is defined, so that the clamping device 100 on the slide 400 can always maintain a predetermined position, thereby ensuring the cutting accuracy of the edge skin.

[0063] In this embodiment, the edge skin cutting machine also includes a crossbeam 910, which is supported above the base 500 by a column 800, and the cutting head 200 is supported on the crossbeam 910; the cutting head 200 includes a vertical plate 201, a power wheel 202 supported on the vertical plate 201, a driven wheel 203 and a tension wheel 204, and a cutting line 205 connected end to end to form a ring and linked to the power wheel 202, the driven wheel 203 and the tension wheel 204, and the cutting line 205 is close to the clamping device 100. A section forms a cutting section, and the cutting section extends along the second horizontal direction; the cutting head 200 also includes a second sliding drive member 206 and a second rotating drive member 207, the second sliding drive member 206 is fixedly supported on the beam 910, and the moving end of the second sliding drive member 206 is fixedly connected to the vertical plate 201 to drive the vertical plate 201 to move horizontally along the first horizontal direction; the second rotating drive member 207 is drivingly connected to the power wheel 202; the cutting head 200 is arranged in a plurality of groups distributed along the first horizontal direction.

[0064] The crossbeam 910 is supported above the base 500 by the column 800. This design not only provides the support structure required by the cutting head 200, but also ensures the stability and accuracy of the cutting head 200 during operation. The cutting line 205 moves along a predetermined circular path driven by the power wheel 202, thereby achieving the cutting of the edge skin. The tensioning wheel is a gravity tensioning structure, that is, the counterweight drives one end of the handle hinged on the vertical plate 201 to rotate, and the other end of the handle is connected to the guide wheel to tension the cutting line 205 connected end to end.

[0065] The second sliding driving member 206 drives the vertical plate 201 to move the cutting head 200 laterally along the first horizontal direction, so that the edge skins of different lengths can be cut, thereby improving the use flexibility of the edge skin cutting machine.

[0066] The second rotating driving member 207 is drivingly connected to the power wheel 202. This design allows the second rotating driving member 207 to drive the power wheel 202 to rotate by providing power, thereby driving the cutting line 205 to move along the circular path.

[0067] The cutting heads 200 are arranged in a plurality of groups distributed along the first horizontal direction, which means that the edge skin cutting machine has a plurality of independent cutting systems, and can cut longer edge skins at the same time, thereby improving the efficiency of edge skin cutting.

[0068] Embodiment 2:

[0069] Reference Figure 1-Figure 7 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0070] The clamping unit 1 also includes a push rod 14 and an elastic member 15, the elastic member 15 maintains an elastic force applied to the pressure plate 13 to switch from a released position to a clamped position; the push rod 14 is vertically oriented and vertically slidably connected to the base 11; the edge skin cutting machine also includes a telescopic driving member 300 supported on the loading and unloading station and the cutting station respectively, such as supported on the base 500, the telescopic driving member 300 can correspond to the position of the push rod 14, so that the telescopic driving member 300 can selectively load the push rod 14, and then the push rod 14 selectively loads the pressure plate 13, and the pressure plate 13 selectively overcomes the elastic force of the elastic member 15 and switches from the clamped position to the released position.

[0071] In this embodiment, the push rod 14 loads the pressure plate 13 by pushing the pressure plate upward. When the upward force driving the push rod 14 disappears, the push rod 14 moves downward under the gravity and the pressure of the pressure plate 13. The power source driving the push rod 14 to slide is separated from the clamping device 100, which can reduce the volume of the clamping device 100, improve its compactness, reduce its curb weight, and facilitate its flexible switching between the cutting station and the loading and unloading station. When the slide 400 is in the loading and unloading station, the telescopic drive member 300 corresponds to the position of the push rod 14. At this time, the telescopic drive member 300 can selectively load the pressure plate 13, so that the pressure plate 13 overcomes the elastic force of the elastic member 15 and switches to the released position, thereby facilitating the loading and unloading operation of the edge skin.

[0072] Furthermore, under the elastic force of the elastic member 15 , the pressing plate 13 can maintain the pressing position under normal conditions, thereby improving the reliability of the clamping device.

[0073] Embodiment 3:

[0074] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0075] The top end of the push rod 14 forms a loading portion D, and the lower part of the pressure plate 13 forms a force-bearing portion E. The force-bearing portion E is closer to the support plate 12 relative to the hinge point of the pressure plate 13 on the base 11, so as to form a loading force arm between the force-bearing portion E and the hinge point of the pressure plate 13 on the base 11; when the loading portion D loads the force-bearing portion E, the pressure plate 13 overcomes the elastic force of the elastic member 15 and switches to a released position; a clamping portion F is formed on the plane of the pressure plate 13 close to the support plate 12, and the clamping portion F presses the position above the middle of the arc surface of the edge skin, so that the clamping portion F applies an inclined downward clamping force to the edge skin.

[0076] The top of the push rod 14 forms a loading part D, and the lower part of the pressure plate 13 is designed with a force-bearing part E. The design of these two parts enables the pressure plate 13 to swing effectively when the push rod 14 applies force to the force-bearing part E. In particular, the force-bearing part E is closer to the support plate 12 relative to the hinge point of the pressure plate 13 on the base 11, thereby forming a loading force arm between the force-bearing part E and the hinge point. By reasonably setting the length of the force arm, the relationship between the loading force and displacement of the push rod 14 can be balanced, thereby realizing the function of loosening or tightening the pressure plate 13.

[0077] At the same time, the force-bearing portion E is close to the support plate 12 , so the space between the pressing plate 13 and the support plate 12 is more effectively utilized, thereby further improving the structural compactness of the clamping unit 1 .

[0078] A pressing portion F is designed on the plane of the pressing plate 13 close to the supporting plate 12, and this portion is specifically used to press the edge skin. In particular, the pressing portion F is designed to be located above the middle of the arc surface of the edge skin. Such a design can ensure that the pressing portion F can apply a downwardly inclined pressing force to the edge skin, and this force can play a certain role in pulling the edge skin downward, thereby improving the stability of the edge skin during the cutting process.

[0079] Embodiment 4:

[0080] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0081] The clamping unit 1 also includes a roller 16, which is hinged on the pressure plate 13 along a first horizontal direction, and the roller 16 forms a force-bearing part E on the pressure plate 13; the top surface of the loading part D is an arc surface whose axis extends along the first horizontal direction. When the loading part D loads the roller 16, the loading part D and the roller 16 remain tangent, and the tangent point between the loading part D and the roller 16 and the line connecting the hinge point of the roller 16 on the pressure plate 13 form an angle a relative to the vertical axis, where 0°<a<90°.

[0082] In this embodiment, the roller 16 can rotate when squeezed by the loading part D, thereby reducing the running resistance of the loading part D, reducing the friction and wear between the loading part D and the force-bearing part E, and making the transmission of the loading force smoother and more uniform.

[0083] The top surface of the loading portion D is designed as an arc surface with an axis extending along the first horizontal direction. This design allows the loading portion D to maintain a tangent state when interacting with the roller 16, thereby ensuring that the transmission of the loading force is more stable and reliable.

[0084] The range of the angle a is limited to 0°<a<90°, which means that the line between the tangent point and the hinge point is tilted downward to ensure that the pressure plate 13 can be subjected to an inclined upward force, thereby driving the pressure plate 13 to swing and ensuring that the pressure plate 13 can be reliably switched to the released position.

[0085] Embodiment 5:

[0086] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0087] The elastic member 15 is configured as a tension spring, and a first connection portion G is formed on the pressure plate 13.
