Among them, door and window facilities are one of the basic facilities of buildings, and heat insulation, sound insulation, and wind insulation of doors and windows are the most basic requirements. Existing doors and windows generally adopt an opening and closing structure, with poor airtightness, which is prone to the infiltration of rainwater and wind, and cannot isolate external industrial noise. Therefore, installing door frame sound insulation strips to fill the gaps in windows can play a role in preventing insects, dust, water, and leakage, as well as partial sound insulation, improving the living environment of users.

During the installation of doors and windows, sound insulation strips are usually installed first. When making sound insulation strips, it is necessary to process the sound insulation strips into shapes suitable for doors and windows, which can achieve better effects. Currently, the main method for processing sound insulation strips is that two people hold both sides of the cutting equipment respectively, and then operate the cutting equipment to cut on the sound insulation strips.

A strip inlet is arranged in the middle and lower part of the sealing plate.

[0015] Working principle: When using this sound insulation strip processing device, first send the sound insulation strip into the cutting box through the conveyor belt and the strip inlet, and continuously transport it to the placement plate. After the length reaches the dual-purpose plate, the cutting structure in the cutting box starts to cut. The first motor drives the first synchronous pulley, and the first synchronous pulley drives the second synchronous pulley to rotate synchronously through the belt, so that the lead screw pair connected to the second synchronous pulley rotates. The rotation of the lead screw pair drives the nut pair connected to the upper part to move. The slider connected to the nut pair slides on the linear slide rail, thereby limiting the direction of the movement track of the nut pair, and driving the cutter at the lower part of the nut pair to perform a left-right cutting movement sliding in the through groove, so as to complete the cutting of the input sound insulation strip to the specified length. The cut sound insulation strip is continuously pushed onto the connecting plate by the lower inclined push plate driven by the first air cylinder. While the lower inclined push plate is continuously pushing, the folding sleeves on both sides also perform a sliding outer folding expansion synchronously, thereby forming a squeezing force on the limiting plate and the spring in the inner groove, and squeezing the limiting plate into the inner part of the inner groove through the action of the spring, so as to push the sound insulation strip into the space between two adjacent limiting plates to complete the limiting. And so on, the subsequent sound insulation strips also go through the cutting and pushing processes. For the sound insulation strips between adjacent limiting plates, through multiple first electric telescopic rods inside the stepped protective shell and the connecting rods connected to the first electric telescopic rods, the sound insulation strips between the limiting plates form a step difference by being pushed at different time intervals, and then are transported onto the conveying platform. Through the continuous pushing of the first electric telescopic rods and the connecting rods, and the sliding conveying action of the sliding group on the conveying platform, the sound insulation strips quickly enter the cutting track and sequentially enter the lower holes of the connecting inclined hole plate. Finally, they are limited by the inclined support plate in the rising state. Then, stop the pushing action of the first electric telescopic rods and the connecting rods, start the second air cylinder, and drive the third motor and the first blade to move through the pushing of the second air cylinder, and cut the part of the sound insulation strip leaking from the rear hole of the lower connecting inclined hole plate at a 45-degree angle to complete the 45-degree cutting of the rear corner of the sound insulation strip. During this period, the second motor can drive the gear, and the gear drives the engaged rack column to move, thereby driving the electric limiting plate and the stabilizing column to move. At the same time, together with the stabilizing column, it pushes the dual-purpose plate and the fixed block connected to the dual-purpose plate to move. The fixed block moves more stably through the leg plate and the rolling column. The movement of the fixed block drives the connecting inclined hole plate to change its position, and the cutting setting of the length of the sound insulation strip can be completed, which is beneficial for sound insulation strips required for different lengths and widths of door frames, with a wider and more comprehensive application range. Then, lower the height of the inclined support plate through the electric push rod, and then start the first electric telescopic rod to drive the connecting rod to push the cut sound insulation strip to the position of the inclined support plate in the descending state. The bottom of the sound insulation strip contacts the corresponding limiting auxiliary moving wheels, and through the controller to jointly control the electric motors, control the rotation interval of each electric motor, and output the sound insulation strips in stages to form a stepped state opposite to the entry. Finally, through the holes of the second hole plate, and then cut by the second blade driven by the fourth motor.At the same time, the third electric telescopic rod is used for bevel extension, the front parts of multiple sound insulation strips are cut at a 45-degree angle, and finally the sound insulation strips are transported out of the conveying platform through the limit assisting moving wheels, so as to complete the bevel cutting of the two corners of the sound insulation strips. The whole working process is convenient for the 45-degree bevel cutting of the sound insulation strips, which is beneficial to the alignment of angles and makes the overall door frame edge sealing more beautiful and practical. At the same time, it is also beneficial to improve the processing efficiency of the door frame sound insulation strips for window and door processing.

[0016] The present invention provides a processing device for door frame sound insulation strips for window and door processing. It has the following beneficial effects:

[0017] 1. In the present invention, the sound insulation strips are conveyed to the strip cutting and pushing mechanism through the conveyor belt, and then the strip cutting and pushing mechanism cuts the sound insulation strips to equal lengths and transports them by pushing. They are transported to the sub-pushing mechanism for limit setting and various pushes. By pushing each sound insulation strip to cooperate with the angle cutting mechanism and the secondary cutting mechanism for angle cutting, first, the 45-degree cutting of the rear angle is carried out, and then the 45-degree angle cutting of the front part is carried out to complete the diagonal cutting on both sides, which is beneficial to the sealing of the door frame sound insulation strips. At the same time, the cutting length of the sound insulation strips can be set, and the position of the angle cutting mechanism can be changed, which is beneficial to obtaining the sound insulation strips required for the length and width of different door frames, making the applicable range of the processing device wider, and improving the working efficiency and cutting accuracy at the same time.

[0018] 2. In the present invention, by using the sub-pushing mechanism to push at different time intervals, a step difference is formed in the sound insulation strips between the limit plates, and then they are conveyed onto the conveying platform. Through the continuous pushing of the first electric telescopic rod and the connecting rod, and the sliding conveying effect of the sliding group on the conveying platform, the sound insulation strips quickly enter the cutting track and sequentially enter the multiple holes in the lower part of the connecting inclined hole plate. Finally, they are limited by the inclined support plate in the rising state. Then, the pushing actions of the first electric telescopic rod and the connecting rod are stopped, and the second cylinder is started. The second cylinder drives the third motor and the first blade to move, and cuts the part of the sound insulation strip leaking from the rear hole of the lower connecting inclined hole plate at a 45-degree angle to complete the 45-degree cutting of the rear corner of the sound insulation strip, quickly completing the cutting process of one corner of the sound insulation strip. Then, the second blade driven by the fourth motor is used for cutting. At the same time, the third electric telescopic rod is used for bevel extension, the front parts of multiple sound insulation strips are cut at a 45-degree angle, and finally the sound insulation strips are transported out of the conveying platform through the limit assisting moving wheels, so as to complete the bevel cutting of the two corners of the sound insulation strips, and the cutting efficiency of the overall sound insulation strips is higher.

[0019] 3. In the present invention, the second motor drives a gear, and the gear drives a meshing rack column to move. Consequently, the electric limiting plate and the stabilizing column move, and at the same time, together with the stabilizing column, they push the dual-purpose plate and the fixing block connected to the dual-purpose plate to move. The fixing block moves more stably through the leg plate and the rolling column. The movement of the fixing block drives the connecting inclined hole plate to change its position, enabling the cutting setting of the length of the sound insulation strip to be completed, which is beneficial for sound insulation strips required for door frames with different lengths and widths, and has a wider scope of application.

[0036] The sound insulation strip is conveyed to the strip cutting and pushing mechanism 2 through the conveyor belt 1. The strip cutting and pushing mechanism 2 cuts the sound insulation strip into equal lengths and transports it by pushing. It is transported to the splitting and pushing mechanism 3 for limit setting and various pushes. By pushing each sound insulation strip to cooperate with the angle cutting mechanism 4 and the secondary cutting mechanism 5, angle cutting is performed. First, a 45-degree cut is made at the rear angle, and then a 45-degree cut is made at the front angle to complete the diagonal cutting on both sides, which is beneficial to the sealing of the door frame sound insulation strip. At the same time, the cutting length of the sound insulation strip can be set, and by changing the position of the angle cutting mechanism 4, it is beneficial to obtain the sound insulation strips required for different door frame lengths and widths, making the processing device more widely applicable.

[0041] The cut sound insulation strip is continuously pushed onto the connecting plate 301 by the lower inclined push plate 205 driven by the first cylinder 204. While the lower inclined push plate 205 is continuously pushing, the folding sleeves 206 on both sides are also sliding and unfolding outside the sleeve synchronously, thereby forming a squeezing force on the limiting plate 304 and the spring 303 in the inner groove 302, and squeezing the limiting plate 304 into the inner part of the inner groove 302 through the action of the spring 303, thereby pushing the sound insulation strip between two adjacent limiting plates 304 to complete the limiting.
