Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a sealing strip cutting device. Background Technology

[0002] Sealing strips are strip-shaped or rod-shaped materials, typically made of rubber, installed on structures such as doors and windows to prevent the intrusion or leakage of media, achieving functions such as sealing, sound insulation, or heat insulation. During the production and processing of sealing strips, longer strips often need to be cut into segments of a certain length to meet usage requirements. Currently, equipment used for cutting sealing strips usually fixes the strip in place before cutting it into segments.

[0003] However, during the cutting process, the sealing strip has a certain degree of flexibility and will bend. If it is fixed and cut at this time, the length of the cut sealing strip will have a large error compared with the target length, which is not conducive to ensuring the processing quality and will affect the use of the sealing strip. Therefore, we propose a sealing strip cutting device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a sealing strip cutting device that can prevent the sealing strip from bending during cutting, thereby avoiding errors during cutting and effectively solving the problems in the background art.

A guide hole is formed in the middle of each T-shaped moving block, and the guide rod is located inside the guide hole. Two parallel racks are arranged inside the strip-shaped groove, and each rack is connected to one of the two T-shaped moving blocks. A clamping assembly is installed on the side of each T-shaped moving block. A toggle assembly is connected to the two racks. The pulling assembly straightens the sealing strip.

[0008] Furthermore, the actuating assembly includes a first motor and a gear. The first motor is mounted on the lower side of the mounting platform, and a gear is fixed on the output shaft of the first motor. The gear meshes with two racks. The input end of the first motor is electrically connected to the output end of an external control switch group. The actuating assembly drives the two racks to move.

The clamping plate is fixed on the telescopic arm of the first electric telescopic rod, and the input end of the first electric telescopic rod is electrically connected to the output end of an external control switch group. The clamping assembly is used to clamp both ends of the sealing strip.

[0010] Furthermore, the adjustment assembly includes a support plate, a moving block, a bidirectional screw, a limiting rod, and a second motor. Two corresponding support plates are fixed to the left and right sides of the mounting platform, and two corresponding moving blocks are arranged between the two support plates. The moving blocks have threaded holes on their sides with opposite threads. A bidirectional screw is threaded into the interior of each threaded hole. The bidirectional screw is welded from two threaded rods with opposite threads and is rotatably connected between the support plates. A limiting hole is provided on the upper side of the moving block, and a limiting rod is slidably connected inside the two limiting holes. The limiting rod is fixed between the two support plates. A second motor is installed on the left side of the left support plate. The output shaft of the second motor is fixed to the left end of the bidirectional screw. The input end of the second motor is electrically connected to the output end of an external control switch group. The position of the two cutting components is adjusted by setting the adjustment assembly.

[0011] Furthermore, the cutting assembly includes a second electric telescopic rod, a blade holder, and a blade. The second electric telescopic rod is mounted on the lower side of the moving block. A blade holder is fixed on the telescopic arm of the second electric telescopic rod, and a blade is fixed on the lower side of the blade holder. The input end of the second electric telescopic rod is electrically connected to the output end of an external control switch group. The sealing strip is cut by setting the cutting assembly.

[0012] Furthermore, the fastening assembly includes a fixing strip, a sliding rod, a fastening plate, a fixing disc, and a spring. Two corresponding fixing strips are fixed on the left and right sides of the tool holder.

The input terminal of the infrared rangefinder is electrically connected to the output terminal of an external control switch group. The infrared rangefinder and reflector correspond to the two blades respectively. The input terminal of the infrared rangefinder is electrically connected to the output terminal of an external control switch group. The distance between the two blades is adjusted by setting the detection component.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This sealing strip cutting device has the following advantages:

[0015] 1. By setting up a clamping assembly, the two ends of the sealing strip to be cut can be placed inside the two connecting frames during use. After placement, the four first electric telescopic rods are activated to move the four clamping plates to fix the two ends of the sealing strip. After fixing, the first motor is activated to rotate the gears. The rotation of the gears drives the two racks to move, which in turn drives the two T-shaped moving blocks. The movement of the two T-shaped moving blocks drives the two connecting frames to move, thus straightening the sealing strip. In this way, the bending of the sealing strip can be effectively avoided during cutting.

[0016] 2. By setting an adjustment component, the second motor can be started to rotate the bidirectional screw when cutting the sealing strip. The rotation of the bidirectional screw drives the two moving blocks to move, and the movement of the two moving blocks drives the two blades to move. At this time, the infrared rangefinder will detect the distance between the reflector and the infrared rangefinder, thereby detecting the distance between the two blades. When the two blades move to the appropriate value, the second motor is turned off, and then the two second electric telescopic rods are started to move the two blade holders and the two blades downward to cut the sealing strip to the appropriate length.

[0017] 3. By setting up fastening components, the two cutter holders will also drive the four adjacent fixing strips to move downwards during the downward movement of the two cutter holders. This will cause the four fastening plates to move downwards. When the four fastening plates are in contact with the sealing strip during the downward movement of the four fastening plates, the sealing strip can be fixed. After fixing, the sealing strip can be further prevented from bending during cutting. Attached Figure Description

[0028] The working principle of the sealing strip cutting device provided by this utility model is as follows: By setting up a clamping assembly, the two ends of the sealing strip to be cut can be placed inside the two connecting frames 41 during use. After placement, the four first electric telescopic rods 42 are activated, causing the four clamping plates 43 to move and fix the two ends of the sealing strip.

When the two blades 63 move to the appropriate value, the second motor 55 is turned off, and then the two second electric telescopic rods 61 are started to move the two blade holders 62 and the two blades 63 downward. During the downward movement of the two blade holders 62, the four adjacent fixing strips 71 will also move downward, thereby causing the four fastening plates 73 to move downward. During the downward movement of the four fastening plates 73, when they are in contact with the sealing strip, the sealing strip can be fixed. After fixing, the two blades 63 are controlled to continue downward to cut the sealing strip to the appropriate length.
