Technical Field
[0001] This utility model relates to the field of sealing strip technology, and in particular to an electric fixed-arc bending device based on a novel sealing strip. Background Technology
[0002] Sealing strips for building doors and windows refer to elastic strip or rod-shaped materials used on building door and window components, such as the joints between glass and glazing bead, glass and frame / sash, frame and sash, and sashes. They can prevent leakage or intrusion of internal and external media (rainwater, air, dust, etc.) and prevent or reduce damage caused by mechanical vibration and impact, thereby achieving functions such as sealing, sound insulation, heat insulation and shock absorption.
[0003] Sealing strips need to be bent during the production process to fit the door and window. In the existing technology, the sealing strips are bent by heating with a bending device so that the sealing strips can be better matched for installation.
[0004] Traditional bending equipment mostly relies on manual operation to complete the bending process. This method is not only time-consuming and labor-intensive, but also makes it impossible to adjust the bending shape and often results in inconsistent bending quality. In addition, when the sealing strip is being bent during equipment operation, the lack of a fixed feeding angle makes it easy for the sealing strip to shift, resulting in inconsistent bending quality. Therefore, to address these issues, a novel electric fixed-arc bending device for sealing strips is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a novel electric fixed-arc bending device for sealing strips, which aims to improve the problems of manual bending of sealing strips in the prior art, such as the inability to adjust the bending shape and the easy deviation during the bending process.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A novel electric fixed-arc bending device for sealing strips includes an operating table. A protective cover is fixedly connected to the bottom of the operating table. A positioning roller is rotatably connected to the middle of the protective cover. A guide block is fixedly connected to the top of the positioning roller. A guide groove is formed in the middle of the guide block. A sleeve is rotatably connected to the middle of the side of the operating table near the positioning roller. A worm gear sleeve is fixedly connected to the outside of the sleeve. A motor is fixedly connected to the top of the operating table away from the positioning roller. A worm gear is fixedly connected to the drive end of the motor. A turntable is fixedly connected to the top of the sleeve. A heating roller is fixedly connected to the top of the turntable. A guide assembly for guiding the sealing strip is provided at the top of the operating table.
[0008] As a further description of the above technical solution:
[0009] The guide assembly includes three guide wheels 1, the bottom ends of the three guide wheels 1 are rotatably connected to the top of the operating table, and the top of the operating table is rotatably connected to three guide wheels 2.
[0010] As a further description of the above technical solution:
[0011] A connecting block is fixedly connected to the side of the operating table away from the positioning roller. A collar is fixedly connected to the side of the connecting block away from the operating table. Four openings are provided in the middle of the collar. A clamping block is slidably connected to the inner wall of the opening. A stop block is fixedly connected to the outside of the clamping block. A circular spring is slidably connected to the outside of the collar.
[0012] As a further description of the above technical solution:
[0013] The inner wall of the turntable is rotatably connected to the outside of the protective cover, and the inner wall of the sleeve is rotatably connected to the outside of the protective cover.
[0014] As a further description of the above technical solution:
[0015] The top of the turntable is rotatably connected to the bottom of the guide block;
[0016] As a further description of the above technical solution:
[0017] The outer teeth of the worm are meshed with the outer teeth of the worm wheel sleeve, and a clamping wheel is rotatably connected to the side of the clamping block away from the abutment block;
[0018] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by starting the motor to drive the worm gear to rotate left and right, the worm gear sleeve drives the heating roller to heat and bend the sealing strip in two opposite directions through the turntable fixed by the sleeve. This achieves heating and bending by rotating left and right, effectively reducing the time and labor intensity of manual operation, while adapting to the production needs of sealing strips of different specifications and shapes.
[0024] 2. In this utility model, the sealing strip is inserted into the collar to squeeze the clamping wheel. The clamping wheel fixes the sealing strip under the elasticity of the abutment block.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3 This utility model provides one embodiment: a novel electric fixed-arc bending device for sealing strips, including an operating table 1, which provides a stable support platform for the entire device. A protective cover 2 is fixedly connected to the bottom of the operating table 1, providing protection for the internal components. A positioning roller 3 is rotatably connected to the middle of the protective cover 2, which provides support for the guide block 4 and assists in the positioning and guiding of the sealing strip.
[0033] A guide block 4 is fixedly connected to the top of the positioning roller 3. The guide block 4 is designed to ensure the stability of the rubber strip during the bending process. A guide groove 5 is opened in the middle of the guide block 4. The rubber strip slides in the guide groove 5, guiding the rubber strip to move correctly to the heating and bending position. A sleeve 6 is rotatably connected to the middle of the side of the operating table 1 near the positioning roller 3. The inner wall of the middle of the sleeve 6 is rotatably connected to the outside of the protective cover 2. The sleeve 6 provides support for the rotation of the turntable 10 and achieves rotation through the cooperation of the worm gear sleeve 7 and the worm 9.
[0034] refer to Figure 1 The top of the operating table 1 is equipped with a guide assembly for guiding the sealing strip. The guide assembly includes three guide wheels 12, the bottom ends of which are rotatably connected to the top of the operating table 1. Three guide wheels 13 are rotatably connected to the top of the operating table 1. The guide wheels 13 cooperate with the guide wheels 12 to guide the sealing strip, allowing it to smoothly enter the guide groove 5 of the guide block 4. The guide wheels 13 are fixed relative to the guide wheels 12. Two support legs 21 are fixedly connected to the bottom of the operating table 1, providing stable support for the operating table 1.
[0035] refer to Figure 2 , Figure 3 A worm gear sleeve 7 is fixedly connected to the outside of the sleeve 6. The bottom end of the worm gear sleeve 7 is rotatably connected to the inner wall of the protective cover 2. The rotation of the worm gear sleeve 7 at the top of the protective cover 2 causes the sleeve 6 to rotate. A motor 8 is fixedly connected to the top of the operating table 1 on the side away from the positioning roller 3. A worm 9 is fixedly connected to the drive end of the motor 8, providing power for the rotation of the worm 9. The two outer ends of the worm 9 are rotatably connected to the middle of the left and right sides of the protective cover 2. This design ensures the stable rotation of the worm 9.
[0036] A turntable 10 is fixedly connected to the top of the sleeve 6. The turntable 10 is driven to rotate by the rotation of the worm gear sleeve 7, which drives the heating roller 11 to heat and bend the sealing strip. The inner wall of the middle part of the turntable 10 is rotatably connected to the outside of the protective cover 2 to achieve stable rotation of the turntable 10. The top of the turntable 10 is rotatably connected to the bottom of the guide block 4. The outer teeth of the worm 9 are meshed with the outer teeth of the worm gear sleeve 7. The heating roller 11 is fixedly connected to the top of the turntable 10. The heating roller 11 is fixed to the top edge of the turntable 10 and is equipped with heating wires inside, which can heat the sealing strip that passes through, softening it for bending.
[0037] refer to Figure 1 The top of the operating table 1 is provided with a guide assembly for guiding the sealing strip. The guide assembly includes three guide wheels 12, the bottom ends of which are rotatably connected to the top of the operating table 1. The top of the operating table 1 is rotatably connected with three guide wheels 23, and the bottom of the operating table 1 is fixedly connected with two support legs 21.
[0038] refer to Figure 4 A connecting block 14 is fixedly connected to the side of the operating table 1 away from the positioning roller 3. The connecting block 14 connects to the collar 15, providing an installation position for the collar 15. The collar 15 has an annular groove on its outer side, through which the sealing strip passes and is locked. Four openings 16 are provided in the middle of the collar 15. Clamping blocks 17 are slidably connected to the inner wall of the openings 16, providing a channel for the movement of the clamping blocks 17. Under the action of the circular spring 19, the clamping blocks 17 compress and restrict the sealing strip through the clamping roller 20, ensuring the stability of the strip during movement.
[0039] A stop block 18 is fixedly connected to the outside of the clamping block 17, and a coil spring 19 is slidably connected to the outside of the collar 15. The stop block 18 and the coil spring 19 cooperate to provide elastic restoring force for the clamping block 17. The coil spring 19 is externally slidably connected to the four stop blocks 18 on opposite sides. The coil spring 19 provides elastic force to the clamping block 17, enabling the clamping wheel 20 to adapt to sealing strips of different sizes and effectively constrain the strips. The clamping wheel 20 is rotatably connected to the side of the clamping block 17 away from the stop blocks 18. When the sealing strip is inserted into the collar 15, the clamping wheel 20 is squeezed by the strip and, under the elastic action of the stop block 18 and the coil spring 19, constrains the sealing strip and assists in the movement of the strip.
[0040] Working principle: The sealing strip is inserted into the collar 15 and squeezes the clamping wheel 20 inside the collar 15. The clamping wheel 20 is restrained by the elasticity of the abutment block 18. At this time, the sealing strip is pushed to slide between the first guide wheel 12 and the second guide wheel 13 until it enters the guide groove 5 of the guide block 4. This helps the sealing strip to enter the inner wall of the guide groove 5 correctly and ensures the stability of the strip during bending.
[0041] After the sealing strip moves out of the guide groove 5, start the motor 8, which drives the worm gear 9 to rotate left and right, causing the heater inside the worm gear sleeve 7 to heat and bend the strip. When it is necessary to bend the strip in another direction, start the motor 8 to drive the worm gear 9 to rotate in the opposite direction, thereby achieving bending of the strip in both directions.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
