Technical Field

[0001] The utility model relates to the technical field of test auxiliary equipment, in particular to a rubber strip cutter. Background Art

[0002] Testing the tensile strength, viscosity and other properties of hot melt adhesives needs to be done in the laboratory. Before testing the properties of hot melt adhesives, the staff will roll the hot melt adhesive into a sheet, then cut it to a suitable size so that the hot melt adhesive sheet can be placed in the adhesive strip cutter, and then cut the hot melt adhesive sheet through the adhesive strip cutter, so that the hot melt adhesive sheet is cut into multiple adhesive strips. After the adhesive strips are prepared, the staff can take multiple adhesive strips and do multiple groups of experiments to ensure the accuracy of the test results.

[0003] The existing rubber strip cutter usually includes a cutting platform, a clamping and fixing frame, and a cutting assembly. The clamping and fixing frame is hinged to the cutting platform at one edge, and the cutting assembly includes a knife holder slidably arranged on the clamping and fixing frame and a cutting blade arranged on the knife holder.

[0004] When the existing rubber strip cutter is flipped over and close to the cutting table by the clamping fixing frame, the cutting blade will partially contact the hot melt rubber sheet first. At this time, the clamping fixing frame does not press the hot melt rubber sheet, which will cause a certain deformation of the cutting starting end of the hot melt rubber sheet, resulting in a certain difference in the appearance shape of the cut rubber strips, which is not conducive to ensuring the accuracy of the test results.

[0040] Reference Figures 1 to 4 The rubber strip cutter is provided with a first direction and a cutting direction. The cutting direction and the first direction are arranged perpendicular to each other.

[0041] The rubber strip cutter of the present solution comprises: a cutting platform 100 , a pressing and fixing frame 200 and a cutting assembly 300 .

[0042] Specifically, the cutting table 100 is provided with a material placement area 110, a second end and a first end. The material placement area 110, the second end and the first end are arranged along the cutting direction, and specifically, the second end and the first end are respectively arranged at two ends of the material placement area 110 in the cutting direction.

[0043] The first end portion is provided with a first knife groove 121 , and the material placement area 110 is communicated with the first knife groove 121 .

[0044] The second end portion is provided with a second knife placement groove 131 , and the material placement area 110 is communicated with the second knife placement groove 131 .

[0045] The first knife slot 121 and the material placement area 110 , as well as the second knife slot 131 and the material placement area 110 , are separated by a plurality of baffle plates arranged along the first direction.

[0046] The clamping and fixing frame 200 is hingedly connected to the cutting table 100 , and specifically, the clamping and fixing frame 200 is hingedly connected to the first end portion.

[0047] Specifically, in the present embodiment, the clamping and fixing frame 200 is fixedly mounted with a flip handle 210. When it is necessary to flip the clamping and fixing frame 200 upward to open the rubber strip cutter, the staff can pull the flip handle 210 to flip the clamping and fixing frame 200, thereby opening the rubber strip cutter. By providing the flip handle 210, it is easier to open the rubber strip cutter.

[0048] The clamping fixing frame 200 is installed with a plurality of clamping structures 220 , and the plurality of clamping structures 220 are arranged at equal intervals along the first direction, and a tool-feeding space is formed between any two adjacent clamping structures 220 .

[0049] An elastic member is arranged between the clamping fixing frame 200 and the clamping structure 220. Specifically, in this embodiment, the elastic member is arranged as a compression spring. The elastic member enables the clamping structure 220 to always have a tendency to move away from the clamping fixing frame 200 and approach the cutting table 100, so that the clamping structure 220 can compress the rubber strip.

[0050] Specifically, in this embodiment, the clamping structure 220 includes two pressing plates 221, which are arranged at intervals and opposite to each other. The pressing plates 221 are adjustably connected to the clamping fixing frame 200. Through such a setting, the width of the clamping structure 220 is adjustable to adapt to the requirements of cutting rubber strips of different widths.

[0051] A hydraulic telescopic rod 230 is provided between the cutting table 100 and the pressing and fixing frame 200, and the two ends of the hydraulic telescopic rod 230 are respectively hinged to the cutting table 100 and the pressing and fixing frame 200. By providing the hydraulic telescopic rod 230, after the pressing and fixing frame 200 is opened upward, the hydraulic support rod can support the pressing and fixing frame 200, thereby avoiding the trouble of the staff to keep the pressing and fixing frame 200 open with one hand and place the film with the other hand during the process of placing the rubber strip.

[0052] The slitting assembly 300 includes a slitting blade 310 and a slitting blade holder 320. The slitting blade holder 320 is slidably connected to the clamping and fixing frame 200, and the slitting blade holder 320 can slide along the slitting direction relative to the clamping and fixing frame 200. After the clamping and fixing frame 200 and the clamping structure 220 clamp the rubber strip, the staff drives the slitting blade holder 320 to slide parallel to the slitting direction.

[0053] Specifically, in this embodiment, a guide assembly 330 is disposed between the clamping and fixing frame 200 and the cutting knife seat 320 .

[0054] The guide assembly 330 includes a guide rail 332 and a guide seat 331. The guide seat 331 and the guide rail 332 are respectively arranged on the cutting knife seat 320 and the clamping and fixing frame 200. The guide rail 332 is arranged parallel to the cutting direction, and the guide seat 331 is slidably connected to the guide rail 332. Specifically, in this embodiment, the guide rail 332 is fixedly installed on the clamping and fixing frame 200, and the guide seat 331 is fixedly installed on the cutting knife seat 320.

[0055] Specifically, in this embodiment, the cutting knife seat 320 is fixedly installed with a pushing handle 321. When the hot melt adhesive sheet needs to be cut, the staff can push the handle 321 to drive the cutting knife seat 320 to move along the first direction, which can enable the staff to exert better force to ensure that the hot melt adhesive sheet can be cut smoothly. By setting the pushing handle 321, it can be easier for the staff to cut the hot melt adhesive sheet.

[0056] The number of the slicing blades 310 is set to be multiple, and the multiple slicing blades 310 are arranged along the first direction, and the slicing blades 310 are arranged one-to-one corresponding to the tool-moving spaces. The slicing blades 310 pass through the tool-moving space and slide relative to the tool-moving space.

[0057] Specifically, in the present embodiment, the slitting blade 310 is adjustably connected to the slitting blade holder 320, and the slitting blade 310 can be adjusted along the first direction relative to the slitting blade holder 320, so that the rubber strip slitter can adjust the width of the slitting rubber strip. Specifically, in the present embodiment, the end of the slitting blade 310 is fixedly connected with an adjustment block, and the adjustment block is slidably connected to the slitting blade holder 320 along the first direction. The adjustment block and the slitting blade holder 320 are fixed by a first bolt and a first nut. The slitting blade holder 320 is provided with a strip hole, and the first bolt passes through the strip holes on the adjustment block and the slitting blade holder 320. The first bolt is threadedly connected with the first nut, and the head of the first bolt is pressed against the adjustment block, and the first nut is pressed against the slitting blade holder 320 to achieve the fixing of the adjustment block and the slitting blade holder 320. Those skilled in the art can adjust the spacing between two adjacent slitting blades 310 according to actual needs, so as to cut rubber strips of different widths to meet the test requirements.

[0058] At the same time, through the adjustment block, the first bolt and the first nut and other structures, the cutting blade 310 can be removed from the cutting blade seat 320. When the cutting blade 310 is damaged after being used for a long time, the staff can remove the cutting blade 310 and then replace it with a new cutting blade 310 so that the strip cutter can continue to be used.

[0059] When the present adhesive strip cutter is used, the staff first places the hot melt adhesive sheet in the material placement area 110, and then the staff drives the pressing and fixing frame 200 to flip, so that the pressing and fixing frame 200 moves downward. During the downward movement of the pressing and fixing frame 200, the cutting blade 310 will enter the first knife groove 121. Through such a setting, the cutting blade 310 will not contact the hot melt adhesive sheet during the pressing and fixing frame 200, thereby avoiding deformation of the cutting starting end of the hot melt adhesive sheet, avoiding differences in the shapes of the cut adhesive strips, and thus ensuring the accuracy of the test results. After the pressing structure 220 completely presses the adhesive strip, the staff pushes or pulls the push handle 321, so that the cutting knife seat 320 drives the cutting blade 310 to move, thereby cutting the hot melt adhesive sheet. After the cutting blade 310 moves to the second knife groove 131, the rubber strip is cut. The cutting blade 310 moves to the second knife groove 131 to ensure that multiple rubber strips are completely separated to ensure the cutting quality of the rubber strip. After the rubber strip is cut, the staff pulls the flip handle 210 to flip the clamping frame 200 upward, and the hydraulic telescopic rod 230 supports the clamping frame 200 so that the clamping frame 200 maintains a certain angle with the cutting table 100. Then the cutting knife seat 320 slides down to the first end due to its own gravity to wait for the next cutting work.

[0060] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
