[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0039] like Figures 1 to 3 As shown, the trimming assembly 10 according to the first embodiment of the invention includes a mounting seat 100 and a knife particle 200. The mounting seat 100 includes a fixed block 110, a sliding block 120, a mounting block 130 and a first adjusting member. There are two fixed blocks 110. The sliding block 120 is limited and clamped between the two fixed blocks 110. The sliding block 120 is connected between the two fixed blocks 110 by sliding left and right. The first adjusting member is used to adjust the relative position between the sliding block 120 and the fixed block 110. The first adjusting member can be an electric adjusting member or a manual adjusting member. When the first adjusting member is an electric adjusting member, the electric adjusting member includes but is not limited to a screw nut adjustment mechanism with a scale or an electric push rod with a scale. When the first adjusting member is a manual adjusting member, the manual adjusting member can be optionally a first adjusting knob 140. The structure of the knife particle 200 is as shown in FIG. Figure 4As shown, the blade particle 200 is a square blade particle with a draft angle, and the mounting block 130 is provided with a mounting concave plane 131 matching the blade particle 200, so that the blade particle 200 can be detachably connected in the mounting concave plane 131; based on the shape of the blade particle 200, in order to be able to machine the mounting concave plane 131, the mounting concave plane 131 is provided with avoidance positions 132 at two right angles. The blade particle 200 is provided with four processing edges 210, and each of the processing edges 210 is provided with a trimming blade 211. The trimming blades 211 on different processing edges 210 have different size specifications. For example, the four trimming blades 211 correspond to the processing thickness of 0.5mm, 1mm, 1.5mm, and 2mm strips, respectively. It should be noted that the size specification of the trimming blade 211 specifically refers to the size and shape of the blade. When the user needs to process strips of different thicknesses, the knife grain 200 is first removed from the installation concave plane 131, and the corresponding trimming blade 211 is selected according to the thickness of the strip, and the knife grain 200 is reinstalled to expose the corresponding trimming blade 211. Since the knife grain 200 in the invention is provided with four processing edges 210, the trimming assembly 10 can process at least four strips of different thicknesses, but the invention does not limit the specific shape of the knife grain 200, and the knife grain 200 can also be a regular triangle knife grain or a regular pentagon knife grain, but is not limited thereto.

[0040] like Figures 1 to 3As shown, since the four processing edges 210 of the blade 200 are all provided with trimming blades 211 of different sizes and specifications, once different trimming blades 211 are replaced, there will be a left-right position deviation between the replaced trimming blade 211 and the trimming blade 211 before replacement. In order to compensate for the left-right position deviation, the electric adjustment member or the manual adjustment member can be used to fine-tune the left-right position of the sliding block 120. For the convenience of further explanation, the first adjustment knob 140 is selected as a specific embodiment. Specifically, a first knob connecting block 150 is provided on the right side of the sliding block 120. The first knob connecting block 150 and the fixed block 110 are both fixedly connected to the base 520, so that the first knob connecting block 150 and the fixed block 110 remain in a relatively static state. The first adjustment knob 140 is provided with a first external threaded portion. A through groove 121 is provided in the sliding block 120. A first internal threaded portion 122 is provided between the rear side surface of the sliding block 120 and the through groove 121. An adjusting knob 140 is rotatably connected to the first knob connecting block 150 through a guide sleeve or a bearing, the first external thread portion passes through the first knob connecting block 150 and is threadedly connected to the first internal thread portion 122, the first external thread portion passes through the first internal thread portion 122 and extends into the through groove 121. Since the position of the first adjusting knob 140 is limited by the first knob connecting block 150, when the user rotates the first adjusting knob 140, the sliding block 120 also slides accordingly, thereby driving the knife particle 200 to move left and right. In order to lock the position of the sliding block 120, the mounting base 100 also includes a first handle 310 with a gasket 311, the first handle 310 is provided with a screw, and the base 520 is provided with a threaded hole at the position of the through slot 121, the screw of the first handle 310 passes through the through slot 121 from top to bottom and is threadedly connected to the threaded hole, and at this time the gasket 311 is located above the sliding block 120; when the user tightens the first handle 310, the gasket 311 on the first handle 310 is tightly abutted against the sliding block 120, thereby locking the sliding block 120, and when the user loosens the first handle 310, the gasket 311 on the first handle 310 is separated from the sliding block 120, thereby unlocking the sliding block 120.

[0041] In addition, Figure 4As shown, each of the processing edges 210 is provided with two trimming blades 211. If all the trimming blades 211 on the same processing edge 210 have the same size specifications, when one of the trimming blades 211 is worn, it can be quickly replaced without disassembling the blade 200. If all the trimming blades 211 on the same processing edge 210 have different size specifications, the applicability of the trimming assembly 10 to different strips is further improved. Since the wear of the trimming blades 211 is unavoidable, in order to facilitate the replacement of the worn trimming blades 211, the present invention provides two trimming blades 211 with the same size specifications on each processing edge 210. In order to replace the two trimming blades 211 on the same processing edge 210, as Figures 1 to 4 As shown, the mounting seat 100 also includes a second adjusting member, the sliding block 120 is provided with a dovetail groove 1231 composed of two clamping blocks 123, and the two clamping blocks 123 are arranged at intervals. The mounting block 130 is provided with a dovetail block 131 that matches the dovetail groove 1231, so that the mounting block 130 is slidably connected to the sliding block 120 up and down, and the second adjusting member is used to adjust the relative position between the mounting block 130 and the sliding block 120; the second adjusting member can be an electric adjusting member or a manual adjusting member. When the second adjusting member is an electric adjusting member, the electric adjusting member includes but is not limited to a screw nut adjustment mechanism with a scale or an electric push rod with a scale. When the second adjusting member is a manual adjusting member, the manual adjusting member can be optionally a second adjusting knob 160. For the convenience of further explanation, the second adjusting knob 160 is selected as a specific embodiment. Specifically, a second knob connecting block 170 is connected to the upper side of the sliding block 120, the second adjusting knob 160 is provided with a second external threaded portion, and the mounting block 130 is provided with a second internal threaded portion 132. The second adjusting knob 160 is rotatably connected to the second knob connecting block 170 through a guide sleeve or a bearing, the second external threaded portion passes through the second knob connecting block 170 and is threadedly connected with the second internal threaded portion 132, and the second external threaded portion passes through the second internal threaded portion 132. Since the position of the second adjusting knob 160 is limited by the second knob connecting block 170, when the user rotates the second adjusting knob 160, the mounting block 130 also slides accordingly, thereby driving the knife grain 200 to move up and down; when the trimming blade 211 located at the top is worn, the position of the knife grain 200 can be adjusted upward so that the trimming blade 211 located at the bottom can replace the trimming blade 211 located at the top and worn. In order to facilitate the user to accurately adjust the left and right position of the sliding block 120 and the up and down position of the mounting block 130 , the first adjusting knob 140 and the second adjusting knob 160 are both knobs with scales.

[0042] In order to lock the position of the mounting block 130, the mounting seat 100 further includes a second handle 320, on which a screw is provided, and the two clamping blocks 123 are provided with through holes 1232 extending forward and backward, one of which is a threaded hole, and the screws of the second handle 320 pass through the two through holes 1232 and are threadedly connected with one of the through holes 1232; when the user tightens the second handle 320, the second handle 320 drives the two clamping blocks 123 to approach each other, so that the dovetail groove 1231 formed by the two clamping blocks 123 is narrowed, thereby locking the mounting block 130, and when the user releases the second handle 320, the dovetail groove 1231 formed by the two clamping blocks 123 returns to its original state, thereby unlocking the mounting block 130. It can be understood that the knob with scale in the invention can be replaced by a handwheel with scale, and the handle in the invention can also be replaced by a handwheel.

[0043] Existing strip trimming machines generally trim strips through the following steps: 1. Place the strip to be processed on the unwinder, and the head end of the strip passes through the strip trimming station and is fixed on the winder; 2. Start the winder, and the winder winds the strip so that the strip moves along the strip trimming station; 3. Workers manually adjust the feed amount of each cutter head on the strip trimming station in turn along the moving direction of the strip, and the feed amount of each cutter head should follow the principle of rough processing first and then fine processing; 4. After adjusting the feed amount of all cutter heads, the strip trimming machine can trim the two sides of the strip. It can be seen that while adjusting the feed amount of each cutter head, the strip is also moving, so that the strip in the adjustment process forms waste because it cannot be well trimmed, and the longer the worker's adjustment time, the more waste is generated. In addition, the above adjustment steps need to be repeated for trimming strips of different specifications, which places high labor intensity on workers. Furthermore, since the feed amount of each cutter head needs to be manually adjusted by the workers, high technical requirements are placed on the workers.

[0044] In order to solve the above technical problems, such as Figure 5 and Figure 6As shown, the strip trimming module 20 according to the second aspect embodiment created by the present invention includes the trimming assembly 10 according to the first aspect embodiment created by the present invention, and also includes a trimming platform 400 and two feeding mechanisms 500, the trimming platform 400 is provided with a pad 410 extending forward and backward; the trimming platform 400 is provided with an up and down lifting device 600, the up and down lifting device 600 can be optionally a pneumatic lifting device, the up and down lifting device 600 is connected to a bonding block 610 that can be lifted up and down, the bonding block 610 is located directly above the pad 410, the gap between the pad 410 and the bonding block 610 is a strip moving channel 430, the strip moving channel 430 is used for linear winding of the strip. Before the strip is rolled up, the up-and-down lifting device 600 drives the bonding block 610 to lift upward to reserve enough space for the strip to pass through the strip moving channel 430. After the strip is rolled up, the up-and-down lifting device 600 drives the bonding block 610 downward to approach the moving strip to reduce the vibration of the strip during the rolling process.

[0045] like Figures 6 to 8As shown, the two feeding mechanisms 500 are installed on the trimming platform 400, and a feeding space 420 is reserved in the middle of the trimming platform 400. The two feeding mechanisms 500 are respectively located on the left and right sides of the strip moving channel 430. Each of the feeding mechanisms 500 includes a linear drive device 510 and a base 520. The linear drive device 510 is used to drive the base 520 to move left and right, and each of the bases 520 is provided with a plurality of trimming components 10. Specifically, the base 520 is located on the upper side of the trimming platform 400, and a slider guide mechanism is provided on the lower side of the trimming platform 400. The slider 620 guide mechanism includes two guide rails 610, four sliders 620 and two connecting plates 630. The two guide rails 610 are fixedly connected to the lower bottom surface of the trimming platform 400, and each guide rail 610 is slidably connected to two sliders 620, and each connecting plate 630 is fixedly connected to the two sliders 620. The base 520 is indirectly connected to the two connecting plates 630, respectively, so that the base 520 is slidably connected to the trimming platform 400. The linear drive device 510 includes but is not limited to a cylinder, an electric push rod or a ball screw mechanism. Since the ball screw mechanism has the advantages of stable movement and high precision, the linear drive device 510 created by the present invention can be selected as a ball screw mechanism. The ball screw mechanism includes a servo motor 511, a coupling 512 and a ball screw pair 513, wherein the servo motor 511 is connected to the ball screw pair 513 through the coupling 512, the ball screw pair 513 is fixedly connected to the base 520, and the two connecting plates 630 are fixedly connected to the ball screw pair 513, so that the base 520 can be driven by the servo motor 511 to move left and right. It can be understood that, compared with ordinary motors, the servo motor 511 can more accurately perform the feeding of the trimming assembly 10 and eliminate the cumulative error of the system. Compared with the prior art, all the trimming assemblies 10 on the strip trimming module 20 can be driven by the servo motor 511 to automatically trim the strip located on the strip moving channel 430 according to the width of the strip, so as to realize the full automation of feeding and retracting, thereby improving the trimming efficiency of the strip, reducing the waste generated during the trimming of the strip, and improving the automation level of the strip trimming process.

[0046] In some embodiments of the present invention, the strip may deviate left and right during the winding process, resulting in different cutting depths on both sides of the strip, thereby producing defective products. Figure 7As shown, each base 520 is also provided with a plurality of position-limiting rotating assemblies 30, the trimming assemblies 10 and the position-limiting rotating assemblies 30 are spaced apart along the front-back direction of the base 520, each position-limiting rotating assemblies 30 is located between two trimming assemblies 10, and all the position-limiting rotating assemblies 30 located on the left and right sides are staggered. The position-limiting rotating assemblies 30 include a position-limiting block 31, a position-limiting roller 32 and the mounting seat 100, Figure 1 and Figure 2 It can be seen that the structure of the mounting seat 100 in the limit rotation assembly 30 is consistent with the structure of the mounting seat 100 in the trimming assembly 10, and the limit block 31 in the limit rotation assembly 30 is also provided with a dovetail block 131 matched with the dovetail groove 1231, and the limit roller 32 is rotatably connected to the limit block 31, and the limit roller 32 is aligned with the knife grain 200 front and back. When the two feeding mechanisms 500 feed the strip in the strip moving channel 430, all the limit rollers 32 abut against the moving strip to limit the position of the strip during the winding process to prevent the strip from deviating left and right. It can be understood that since the limit roller 32 can rotate freely, the friction mode between it and the strip is sliding friction, which minimizes the wear of the strip.

[0047] In some embodiments of the present invention, Figure 5 and Figure 7 As shown, in a feeding mechanism 500, the fixing blocks 110 of all the position-limiting rotating assemblies 30 and the fixing blocks 110 of all the trimming assemblies 10 are connected to a cover plate 530. In addition to protecting the mounting seat 100, the cover plate 530 also serves to beautify the product. Figure 7 Attachment Figure 5 Some components in are hidden.

[0048] In some embodiments of the present invention, Figure 7 As shown, all the mounting blocks 130 and the limiting blocks 31 are connected with brushes 700 , and all the brushes 700 protrude from the knife particles 200 or the limiting rollers 32 . The brushes 700 are used to sweep away the cutting chips attached to the strip.

[0049] like Fig. 9As shown, a strip trimming machine according to a third aspect embodiment of the present invention comprises a strip trimming module 20 according to the second aspect embodiment of the present invention, and also comprises an uncoiler (not shown in the drawings), a conveyor 800, a strip trimming device 900 and a reel (not shown in the drawings), wherein the uncoiler, the conveyor 800, the strip trimming device 900 and the reel are arranged sequentially from back to front, wherein the uncoiler is used for placing the coiled strip so that the strip can rotate, the conveyor 800 is used for connecting the uncoiler and the strip trimming device 900, the strip trimming device 900 is used for trimming the edges of both sides of the strip, and the reel is used for winding the strip and providing power for the movement of the strip. Specifically, the strip trimming device 900 includes a frame 910 and a plurality of strip trimming modules 20. The frame 910 is provided with a plurality of strip trimming modules 20. All the strip trimming modules 20 are sequentially installed on the frame 910 from the back to the front. The strip moving channels 430 on all the strip trimming modules 20 are connected in a straight line. When trimming, the feeding mechanisms 500 in all the strip trimming modules 20 should follow the principle of roughing first and then finishing, that is, the feeding amount of the feeding mechanism 500 at the rear should be less than the feeding amount of the feeding mechanism 500 at the front. In addition, an air tank 920 is provided on the frame 910, and the air tank 920 is used to provide compressed air for the pneumatic lifting device in the strip trimming module 20. It can be understood that since the strip trimming device 900 is composed of at least two strip trimming modules 20 and has a modular design, the number of strip trimming modules 20 can be selected according to different processing requirements of the strip. Generally speaking, the strip trimming device 900 is configured with different numbers of strip trimming modules 20 according to the different hardness of the strip. The higher the hardness of the strip, the more strip trimming modules 20 are required.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
