DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1~Figure 3 As shown, a cutting device for producing sealing strips includes a mounting plate 1 and a butt plate 2, a support rod 3 is fixedly connected between the mounting plate 1 and the butt plate 2, a measuring assembly 4 is provided at the outer end of the support rod 3, and the measuring assembly 4 includes a slide plate 401 slidably connected to the outer end of the support rod 3, a measuring plate 402 is fixedly connected between the mounting plate 1 and the butt plate 2, and positioning plates 403 are symmetrically fixedly connected on both sides of the slide plate 401, and the positioning plates 403 are slidably connected to the measuring plates 402. The purpose of this arrangement is that the slide plate 401 is used to control the cutting position of the sealing strip, and during operation, the sealing strip is passed through the slide plate 401, and one end of the sealing strip is against the center position of the butt plate 2, and the positioning plate 403 is positioned to locate the sliding position of the slide plate 401, so as to determine the cutting length of the sealing strip, and the number and position of the support rods 3 are symmetrical, so that the sliding of the slide plate 401 between the mounting plate 1 and the butt plate 2 is more stable, and the inclination of the slide plate 401 is avoided to affect the cutting accuracy of the sealing strip.

[0023] Preferably, a through hole is provided at the center of the mounting plate 1 and the slide plate 401, and the measuring assembly 4 further comprises an electric push cylinder 404 fixedly connected to the top of the slide plate 401, a push rod 405 is slidably connected inside the electric push cylinder 404, and a cutter head 406 is fixedly connected to the other end of the push rod 405. The purpose of this arrangement is that the electric push cylinder 404 is used to drive the cutter head 406 at the bottom end of the push rod 405 to cut the sealing strip.

[0024] Preferably, the measuring assembly 4 further comprises a cutting plate 407 fixedly connected to the side end of the slide plate 401, a cutting groove 408 is provided inside the cutting plate 407, a fixing bolt 409 is threadedly connected to the top end of the positioning plate 403, a scale bar is provided at the outer end of the measuring plate 402, and a measuring groove and a scale pointer are provided at the outer end of the positioning plate 403. The purpose of such a setting is that the setting of the cutting plate 407 enables the cutter head 406 to be completely immersed in the cutting groove 408 inside it, and since the sealing strip is made of rubber, the completely immersed cutter head 406 can completely cut the sealing strip, preventing the broken part of the sealing strip from sticking to each other and affecting the packaging of the sealing strip, and the measuring groove at the outer end of the positioning plate 403 facilitates the observation of the sliding position of the scale pointer on the scale bar at the outer end of the measuring plate 402, thereby improving the accuracy of the cutting of the sealing strip.

[0025] In this embodiment, the sealing strip is first inserted from the through hole at the outer end of the mounting plate 1 and passed through the through hole inside the slide plate 401. Before cutting the sealing strip, one end of the sealing strip is pressed against the center position inside the abutment plate 2, and the slide plate 401 at the outer end of the sliding support rod 3 is slid. At this time, the positioning plate 403 slides on the outer end of the measuring plate 402. The measuring groove and the scale pointer at the outer end of the positioning plate 403 can accurately measure the distance between the abutment plate 2 and the slide plate 401, thereby determining the cutting length of the sealing strip. After determining the cutting length of the sealing strip, the slide plate 401 is fixed to the outer end of the measuring plate 402 using the fixing bolt 409. At this time, when cutting the sealing strip, the electric push cylinder 404 drives the push rod 405 to continuously The connected cutter head 406 descends, so that the cutter head 406 cuts the sealing strip. When the cutter head 406 is completely immersed in the cutting groove 408 inside the cutting plate 407, the cut portion of the sealing strip is completely broken, and the cutting end of the sealing strip is flat, thereby improving the accuracy of the cutting of the sealing strip. The cut sealing strip falls from the gap between the mounting plate 1 and the abutment plate 2, which is convenient for recycling and packaging the cut sealing strip. After the sealing strip completes an operation, the electric push cylinder 404 drives the cutter head 406 connected to the push rod 405 to separate from the cutting plate 407, so that the produced sealing strip passes through the slide plate 401 again, so that it conflicts with the abutment plate 2, and the extruded sealing strip is quantitatively cut again.

[0026] Example 2

[0027] like Figure 1~Figure 4 As shown, the outer end of the mounting plate 1 is fixedly connected to a fixing plate 5, the outer end of the fixing plate 5 is fixedly connected to a first clamping plate 6, the side of the fixing plate 5 away from the mounting plate 1 is fixedly connected to a connecting plate 7, the interior of the connecting plate 7 is slidably connected to a second clamping plate 8, the first clamping plate 6 and the second clamping plate 8 are both semicircular structures, and the inner walls of the first clamping plate 6 and the second clamping plate 8 are provided with staples. The purpose of this arrangement is that the first clamping plate 6 and the second clamping plate 8 can slide out at the exit position of the sealing strip extrusion device, so that the sealing strip can be cut after extrusion, thereby improving the production efficiency of the sealing strip, and the staples on the inner walls of the first clamping plate 6 and the second clamping plate 8 increase the stability of the connection between the mounting plate 1 and the extrusion device, and the installation is simple and convenient, which prevents the mounting plate 1 from being separated from the extrusion device when the cutter head 406 cuts the sealing strip, thereby affecting the accuracy of the cutting of the sealing strip.

[0028] In this embodiment, when installing the cutting device, the second clamping plate 8 inside the sliding connecting plate 7 is used to clamp the discharge pipe of the extrusion device with the first clamping plate 6 and the second clamping plate 8, and the connection between the first clamping plate 6 and the second clamping plate 8 is fixed with bolts. The staples on the inner walls of the first clamping plate 6 and the second clamping plate 8 increase the clamping force with the discharge pipe, thereby preventing the mounting plate 1 from being separated from the discharge pipe of the extrusion device due to vibration during the cutting process of the sealing strip, thereby affecting the accuracy of cutting the sealing strip.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
