[0024] like Figure 1-3 , Figure 5 and Figure 7 As shown:

[0025] A rubber strip processing device includes a transverse plate 501 and a slide bar 102, wherein a slide frame 201 is slidably connected to the transverse plate 501, a fixed portion 202 is fixedly connected to the slide frame 201, a cutting knife 203 is rotatably connected to the fixed portion 202, a transmission portion 103 is slidably connected to the slide bar 102, an adjustment block 106 is slidably connected to the transmission portion 103, a contact head 301 is slidably connected to the slide frame 201, a first compression spring is fixedly connected between the slide frame 201 and the contact head 301, a second compression spring is fixedly connected between the transverse plate 501 and the slide frame 201, a first motor capable of driving the cutting knife 203 to rotate is fixedly connected to the fixed portion 202, and the adjustment block 106 after sliding can be fixed by tightening bolts on the adjustment block 106.

[0026] The entire rubber strip that has been processed and formed passes through the lower side of the cutting knife 203 at a uniform speed, and during the movement of the rubber strip, the transmission part 103 slides synchronously on the slide bar 102 following the rubber strip. During the sliding process of the transmission part 103, the contact head 301 will always be in contact with the upper surface of the transmission part 103, so that the sliding frame 201 gradually overcomes the elastic force of the second compression spring and slides upward on the transverse plate 501. When the transmission part 103 moves to the point where the adjustment block 106 on the transmission part 103 contacts the contact head 301, as the transmission part 103 continues to slide, the adjustment block 106 on the transmission part 103 is adjusted. The block 106 gradually presses the contact head 301 to slide on the sliding frame 201, thereby gradually offsetting the contact head 301 from the transmission part 103. When the contact head 301 is completely offset from the transmission part 103, the sliding frame 201 will slide down quickly due to the elastic force of the second compression spring, thereby causing the cutting knife 203 to fall, completing a cutting operation on the rubber strip. Subsequently, the sliding frame 201 is slid up and reset, and the transmission part 103 is reversely slid and reset, and the subsequent cutting operation is continued, thereby achieving the effect of cutting the entire rubber strip into multiple shorter rubber strips.

[0027] In actual use, the staff can remove the fixing effect of the adjustment block 106 by loosening the bolts, and then operate the adjustment block 106 to slide to a suitable position on the transmission part 103, and then fix the sliding adjustment block 106 by tightening the bolts on the adjustment block 106, and then the uniform speed transportation of the rubber strip and the reciprocating sliding operation of the transmission part 103 can be started. The interval time between multiple cutting operations can be adjusted by manually adjusting the position of the adjustment block 106, so that the entire rubber strip can be cut into multiple rubber strips of suitable lengths according to production requirements in conjunction with the original uniform speed movement setting, thereby meeting actual production requirements;

[0028] In the present application, when it is necessary to adjust the rubber strip to different lengths according to different production requirements, the staff only needs to adjust the position of the adjustment block 106 on the transmission part 103 to adjust the cutting degree of the subsequent rubber strip. The staff does not need to perform complicated program control operations, which simplifies the staff's operating steps and reduces the difficulty of operation.

[0029] like Figure 1-2 and Figure 6-8 As shown:

[0030] It also includes a fixed frame 603 and a fixed plate 101, and two transmission rollers 601 are rotatably connected to the fixed frame 603. The transmission roller 601 located on the right side of the two transmission rollers 601 is fixedly connected with a friction wheel 602, and a friction strip 107 is fixedly connected to the transmission part 103. The friction strip 107 can contact with the friction wheel 602, and the rotation of the friction wheel 602 can drive the friction strip 107 to move. The fixed plate 101 is slidably connected with a slide bar 102, and a third compression spring is fixedly connected between the slide bar 102 and the transmission part 103. Two second motors are fixedly connected to the fixed frame 603, and the output shafts of the two second motors are respectively fixedly connected to the two transmission rollers 601. The fixed plate 101 is fixedly connected with a first electric push rod that can drive the slide bar 102 to slide.

[0031] Insert the rubber strip between the two transmission rollers 601, and then operate the output shafts of the two second motors to rotate, thereby rotating the two transmission rollers 601, so that the two transmission rollers 601 drive the rubber strip to move. In this process, the rotating friction wheel 602 will drive the friction strip 107 to move, and then the transmission transmission part 103 will slide on the slide bar 102 to overcome the elastic force of the third compression spring, thereby completing the subsequent driving adjustment block 106 movement operation. When the transmission part 103 slides to the farthest distance position, operate the slide bar 102 to slide on the fixed plate 101 to separate the friction strip 107 from the friction wheel 602. At this time, the transmission part 103 will be affected by the elastic force of the third compression spring and then slide back to reset, so that the transmission part 103 can achieve automatic reset effect, and then operate the slide bar 102 to slide on the fixed plate 101 to make the friction strip 107 contact with the friction wheel 602, perform subsequent transmission effect, and complete multiple cutting operations.

[0032] like Figure 1 As shown:

[0033] The transmission part 103 is provided with a plurality of scale marks 104 .

[0034] The setting of multiple scale marks 104 allows the staff to accurately adjust the position of the adjustment block 106 according to the relative position relationship between the adjustment block 106 and the multiple scale marks 104 when adjusting the position of the adjustment block 106 according to production needs, providing stable protection for subsequent cutting operations.

[0035] like Figure 5 As shown:

[0036] It also includes a rectangular plate 503, on which a lever 504 is rotatably connected, a cylindrical rod is fixedly connected to the sliding frame 201, and the lever 504 can drive the cylindrical rod to slide, and a third motor that can drive the lever 504 to slide is fixedly connected to the rectangular plate 503.

[0037] When the sliding frame 201 slides down to complete a cutting operation, the operating lever 504 can be operated to slide on the rectangular plate 503, and the lever 504 is used to push the cylindrical rod to make the sliding frame 201 slide upward on the transverse plate 501 to overcome the elastic force of the second compression spring, so that the contact head 301 slides to a reset height, and then after the transmission part 103 slides in the reverse direction and resets, the contact head 301 will smoothly move to a position where it can contact the front side of the transmission part 103, thereby facilitating the next cutting operation.

[0038] like Figure 1 As shown:

[0039] It also includes a matching plate 105 fixedly connected to the lower side of the transmission part 103 .

[0040] The setting of the matching plate 105 can ensure that after the contact head 301 is offset from the transmission part 103, the front side of the contact head 301 always rests against the matching plate 105 during the cutting operation of the cutting knife 203, thereby ensuring that when the sliding frame 201 slides upward to reset, the contact head 301 can smoothly return to the contact position with the upper side of the transmission part 103, and successfully carry out subsequent multiple cutting operations.

[0041] like Figure 5 As shown:

[0042] It comprises an additional part A302 and an additional part B303 which are detachably connected to the contact head 301 by bolts, and the height of the additional part B303 is higher than that of the additional part A302.

[0043] During the actual cutting operation, the staff can connect one of the additional parts B303 or the additional part A302 to the position where the contact head 301 can contact the transmission part 103 by tightening the bolts according to the actual material or molding process of the rubber strip to be cut. Then, when performing subsequent cutting operations, the additional part B303 or the additional part A302 can provide different initial heights for the sliding frame 201, thereby adjusting the subsequent cutting force to ensure the subsequent cutting effect for different types of rubber strips.

[0044] like Figure 4 and Figure 8 As shown:

[0045] It also includes a fixing sleeve 401 , on which a detection rod 402 is slidably connected. The detection rod 402 is provided with a long rod, and the uppermost end of the transmission part 103 can move the long rod. A fourth compression spring is fixedly connected between the fixing sleeve 401 and the detection rod 402 .

[0046] During the movement of the rubber strip, the detection rod 402 will always be pressed against the upper side of the rubber strip by the elastic force of the fourth compression spring. During this process, when the rubber strip continues to have abnormal convexities or concavities, the detection rod 402 will slide adaptively on the fixing sleeve 401. Then, by monitoring the sliding of the detection rod 402, the molding of the rubber strip can be detected to ensure the quality of the finished product.

[0047] A displacement sensor is connected to the detection rod 402 by tightening bolts on the fixing sleeve 401, and then the moving end of the displacement sensor is fixedly connected to the detection rod 402 by bolts. When the detection rod 402 slides, the displacement sensor can receive the signal, and then convert the signal into an electrical signal for transmission, thereby completing the monitoring effect of the sliding condition of the detection rod 402;

[0048] When the transmission part 103 slides back and forth, the uppermost end of the transmission part 103 can move the long rod multiple times, so that the detection rod 402 can regularly slide on the fixing sleeve 401 to overcome the elastic force of the fourth compression spring, thereby testing the operation of the displacement sensor.

[0049] like Figure 1 and Figure 7 As shown:

[0050] It also includes a marking cotton 108 slidably connected to the matching plate 105, and a second electric push rod that can push the marking cotton 108 to slide is fixed to the matching plate 105.

[0051] Before the rubber strip cutting operation is performed, the two driving rollers 601 can be rotated in advance so that the rubber strip can pass between the two driving rollers 601 in advance without performing the cutting operation. During the movement of the rubber strip, the imprint cotton 108 can slide regularly so that the imprint cotton 108 can contact the side of the rubber strip multiple times, thereby leaving multiple pigment marks equidistantly on the side of the rubber strip. Subsequent staff can accurately judge the length of the rubber strip based on the number of pigment marks, which brings convenience to subsequent processing.

[0052] A rubber sealing strip processing technology, using the rubber strip processing equipment:

[0053] Step 1: insert the entire rubber strip after forming between two transmission rollers 601;

[0054] Step 2: operate the adjustment block 106 to slide on the transmission part 103, and then fix the adjustment block 106 by screwing bolts into the adjustment block 106;

[0055] Step 3, operate the two transmission rollers 601 to rotate;

[0056] Step 4: regularly operate the slide bar 102 to slide on the fixed plate 101, and cooperate with the lever 504 to rotate on the rectangular plate 503;

[0057] Step 5: Remove the processed multiple rubber strips for subsequent guarantee work to complete the processing.

[0058] A rubber strip is produced by the rubber sealing strip processing technology.
