Description

Technical Field

[0001] This utility model relates to the field of cosmetic brush bristle processing and forming technology, specifically a cosmetic brush bristle production heat-bonding forming equipment. Background Technology

[0002] Makeup brush head forming refers to the process of using specific techniques and equipment to process the hair (usually called bristles) used to make makeup brushes, so that it is firmly combined with the handle or short metal tube of the makeup brush to form a complete makeup brush head.

[0003] During the thermoforming process of makeup brush bristles, the brush bristles and the metal tube need to be bonded together with adhesive. After the adhesive is applied between the brush bristles and the metal tube, uneven bonding can easily occur during the curing process due to a lack of uniform pressure control. This results in some areas having too little or too much adhesive, affecting the bonding strength and consistency. Consequently, the brush bristles and the metal tube are not firmly bonded, leading to quality problems such as bristle shedding. This causes unstable product qualification rates, increases production costs, and increases rework rates.

[0004] Therefore, this utility model provides a thermoforming equipment for producing cosmetic brush bristles to solve the above problems. Utility Model Content

[0017] 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.

[0018] This utility model provides a thermoforming equipment for producing cosmetic brush bristles, such as... Figures 1-5 As shown, the cosmetic brush head production thermoforming equipment includes an operating table 1, with several placement slots 11 at the bottom of the operating table 1, and a clamping heating mechanism provided in the inner cavity of the operating table 1. The clamping heating mechanism includes a first arc plate 14, and there are several first arc plates 14. The bottom of the first arc plate 14 is fixedly connected to the bottom of the inner cavity of the operating table 1. The inner cavity of the operating table 1 is provided with a threaded rod 8. The outer ring of the threaded rod 8 is threaded with several movable plates 10. A second arc plate 15 is fixedly connected to one side of the movable plate 10. Heating rods 16 are fixedly installed at the bottom of the inner cavities of the first arc plate 14 and the second arc plate 15. A stop plate 12 is slidably connected to the inner cavity of the placement groove 11.

[0019] One end of the threaded rod 8 is rotatably connected to the inner wall of the adjacent operating table 1 via a rotating shaft, and the other end of the threaded rod 8 extends through the inner wall of the adjacent operating table 1 to one side of the operating table 1 via a bushing. The threaded rod 8 can rotate smoothly under the drive of the motor 7, while ensuring the stability of its rotation axis. This structural design allows the moving plate 10 to make precise linear movements along the axial direction of the threaded rod 8, thereby driving the second arc plate 15 to move closer to or away from the first arc plate 14, realizing the clamping and releasing operation of the metal short tube.

[0020] A motor 7 is fixedly installed on one side of the operating table 1. The output shaft of the motor 7 is fixedly connected to the extension end of the threaded rod 8. The precise control of the motor 7 can ensure the stability of the rotation of the threaded rod 8, thereby driving the moving plate 10 to make stable displacement.

[0021] The bottom of the inner cavity of the operating table 1 is provided with a limiting groove 9. Several limiting blocks 18 are slidably connected to the inner cavity of the limiting groove 9. The top of the limiting block 18 is fixedly connected to one side of the corresponding moving plate 10. When the moving plate 10 moves along the threaded rod 8, the limiting block 18 slides in the limiting groove 9, which plays a guiding and limiting role. This structural design ensures that the movement trajectory of the moving plate 10 always stays on the predetermined path, avoiding the problem of uneven clamping caused by the offset or shaking of the moving plate 10.

[0022] A lifting mechanism is provided below the operating platform 1; the lifting mechanism includes a connecting plate 5, and sliding plates 4 are fixedly connected to both sides of the bottom of the connecting plate 5. A connecting rod 13 is fixedly connected to the bottom of the support plate 12. A support frame 3 is fixedly connected to both sides of the bottom of the operating platform 1. Slide grooves 17 are provided on both sides of the inner wall of the support frame 3. The sliding plate 4 slides in the slide groove 17, which ensures the smooth movement of the connecting plate 5 in the vertical direction and avoids damage to the finished product during the ejection process due to the shaking or tilting of the connecting plate 5.

[0023] The bottom of the connecting rod 13 is fixedly connected to the top of the connecting plate 5, and the two ends of the slide plate 4 are slidably connected to the inner cavity of the corresponding slide groove 17. The electric push rod 6 drives the connecting rod 13 and the abutment plate 12 to move upward through the connecting plate 5, pushing out the finished product in the placement groove 11. This structural design simplifies the part removal process, avoids damage to the product that may be caused by manual part removal, and improves part removal efficiency and product integrity.

[0024] A fixed base plate 2 is provided below the operating table 1. The two sides of the fixed base plate 2 are fixedly connected to one side of the adjacent support frame 3. An electric push rod 6 is fixedly installed on the top of the fixed base plate 2. The output end of the electric push rod 6 is fixedly connected to the bottom of the connecting plate 5. The electric push rod 6 can stably output power and drive the abutment plate 12 to complete the ejection action through the connecting plate 5.

[0025] Specifically: During the heat-bonding process of the makeup brush head, personnel first place multiple short metal tubes with makeup brush heads inserted into the corresponding placement slots 11 inside the operating table 1. At this time, glue has been pre-applied between the inner ring of the short metal tube and the makeup brush head. The entire short metal tube is located between the first arc plate 14 and the second arc plate 15. Then, personnel start the motor 7, which drives the threaded rod 8 to rotate. With the cooperation of the limiting block 18 and the limiting groove 9, multiple moving plates 10 are synchronously displaced along the axial direction of the threaded rod 8. The moving plates 10 drive the second arc plate 15 to move towards the corresponding first arc plate 14, thereby bonding the outer surface of the multiple short metal tubes. The metal short tube is evenly clamped and fixed to ensure that it remains stable and is subjected to uniform pressure during subsequent heating. Then, the heating rods 16 set inside the first arc plate 14 and the second arc plate 15 transfer heat to the surface of the metal short tube through the holes, so that the adhesive can fully penetrate into the base of the brush bristles and the interior of the metal short tube, achieving a tight bond between the two. After the thermal bonding is completed, the electric push rod 6 is controlled by the operator. The electric push rod 6 drives multiple abutments 12 to move upward inside the placement groove 11 through the connecting plate 5, thereby pushing the thermally bonded cosmetic brush head and metal short tube assembly out of the placement groove 11, which facilitates subsequent picking and collection operations.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
