It is suitable for automatically heat-melting toy heads after the hair has been sewn on, so as to achieve a stable connection between the hair and the toy head. Background Technology

[0002] In the production of toys with "hair" structures (such as plush toys and plastic toys), securing the hair in the toy head is a crucial step. Currently, the industry mostly uses manual or semi-automated methods: In manual operation, workers hold a hot-melt tool and insert it into the connection hole of the toy head to heat it. This is inefficient and prone to uneven heat melting due to unstable operation, resulting in hair falling off, toy head deformation, and semi-automated equipment lacking stable support for the toy head (making it easy to fall off).

[0003] To solve the above problems, there is an urgent need to design a toy head heat-melting device with a high degree of automation, uniform heat melting, anti-drop and automatic material removal functions, and the ability to ventilate hot air. Utility Model Content

[0004] To address the problems of low efficiency, uneven melting, easy detachment, need for manual removal, and hot air pollution in existing technologies for hot-melt fixing of toy heads, a toy head hot-melt device is provided. This device automatically opens the toy head connection hole, stably supports the toy head, automatically lifts and rotates the hot-melt mechanism, automatically unloads the material, and guides hot air, thereby improving production efficiency and product quality while reducing labor costs and safety risks.

[0056] Rotating mechanism: includes a rotating shaft 7, a bearing housing 8, and a rotating motor 6; the bearing housing 8 is fixed to the bottom surface of the slide 5 by bolts, and the rotating shaft 7 is rotatably mounted in the bearing housing 8 through a deep groove ball bearing; the rotating motor 6 is vertically fixed to the top surface of the slide 5 through an L-shaped mounting seat, and its output shaft is driven to cooperate with the upper end of the rotating shaft 7 through a transmission assembly—the transmission assembly is specifically a synchronous belt pulley assembly, including a driving pulley fixed to the output shaft of the rotating motor 6, a driven pulley fixed to the upper end of the rotating shaft 7, and a polyurethane synchronous belt sleeved on the driving pulley and the driven pulley, so as to realize the smooth transmission of power of the rotating motor 6 and drive the rotating shaft 7 to rotate.

[0057] The heat-melting actuator, used to extend into the connection hole of the toy head 1 and heat-melt and blow-fix the internal hair, includes a heater mounting base 9, a heater 10, an air guide tube, and an air blowing pipe 11.

[0058] The heater mounting base 9 is an L-shaped mounting base structure. Its top end is fixedly connected to the lower end of the rotating shaft 7 through a coupling and rotates synchronously with the rotating shaft 7. The heater 10 is vertically embedded in the center hole of the heater mounting base 9 and is connected to an external temperature controller through wires (to achieve precise temperature control).

[0059] The upper end of the air guide tube is sealed to the output port at the bottom of the heater 10 by a buckle, and the lower end is fixedly connected to the upper end of the air blowing pipe 11 by a thread. This is used to directionally guide the hot air generated by the heater 10 into the air blowing pipe 11 to reduce heat loss.

[0060] The lower end of the air tube 11 is provided with a small air outlet, and large air outlets 111 are symmetrically opened on the left and right sides of the lower end. After the hot air enters the air tube 11 through the air guide tube, it is blown out evenly from the large air outlets 111. With the rotation of the air tube 11, the hair inside the toy head 1 is evenly melted.

[0061] The opening mechanism 14 is used to open the connection hole of the toy head 1 to facilitate the insertion of the air tube 11. It includes an opening base plate 21, a pair of tensioning members 23, an opening cylinder 26, an opening member 27, and a pressure block 30.

[0062] The support plate 21 is a rectangular metal plate, which is horizontally embedded and fixed in the mounting groove of the fixed plate 3. Its top surface is concave to form a support groove 22 that runs through the top and bottom, providing space for the support member 23 to move.

[0063] The two tensioning parts 23 are symmetrical plastic parts. On the same side, they are hinged to the side wall of the support groove 22 by a pin, and the other side is a rotatable free side. The bottom of the tensioning part 23 is integrally formed with a semi-circular support nozzle 24. When closed, the two semi-circular support nozzles 24 are spliced ​​into a complete circle (fitting the connection hole of the toy head 1). On the side of the tensioning part 23, a semi-circular insertion hole 25 is opened at the position of the semi-circular support nozzle 24. When closed, it forms a circular channel for the air blowing tube 11 to pass through.

[0064] The expansion cylinder 26 is fixed to the side of the fixed base plate 3 by a bracket, and its air rod end is fixedly connected to the expansion member 27; the end of the expansion member 27 forms a wedge-shaped expansion structure 28, and the opposite side of the free side of the two tensioning members 23 forms an arc-shaped support surface 29; when the expansion cylinder 26 pushes the expansion member 27 into the support groove 22, the wedge-shaped expansion structure 28 and the arc-shaped support surface 29 cooperate, forcing the free side of the two tensioning members 23 to rotate outward, so that the semi-circular support nozzle 24 opens the connection hole of the toy head 1.

[0065] The pressure block 30 is a metal cover plate, which is screwed onto the top surface of the support plate 21 to limit the vertical displacement of the tensioning member 23 and the opening member 27, and to prevent them from coming out of the support groove 22.

[0066] Support mechanism: Used to support and hold the toy head 1 to prevent it from falling off during the heat-melting process, including lifting cylinder 16, support cylinder 17, and support plate 18.

[0068] During operation, the support cylinder 17 first drives the support plate 18 to extend directly below the toy head 1, and then the lifting cylinder 16 drives the support plate 18 to move upward until it contacts the bottom of the toy head 1, thus achieving stable lifting.

[0069] The ejector mechanism is used to remove the toy head 1 from the spreading mechanism 14 after the heat is melted. It includes an ejector cylinder 19 and an ejector plate 20.

[0070] The ejector cylinder 19 is horizontally fixed on the top bracket of the support cylinder 17; one end of the ejector plate 20 is fixedly connected to the end of the air rod of the ejector cylinder 19, and the other end is provided with an ejector hole (i.e. ejector part) with an outer opening. The opening design makes it convenient for the toy head 1 to be inserted and removed.

[0071] During unloading, the lifting cylinder 16 drives the unloading cylinder 19 to move upward, so that the unloading hole is fitted on the outside of the toy head 1; then the unloading cylinder 19 drives the unloading plate 20 to extend slightly, and the spout enters the unloading hole; finally, the lifting cylinder 16 drives the unloading plate 20 to move downward, completing the unloading and unloading of the toy head 1.

[0072] Ventilation assembly: Used to remove hot air generated during the hot-melt process and improve the working environment, including L-shaped exhaust duct 12 and blower 13.

[0073] The horizontal section (lower side) of the L-shaped exhaust pipe 12 is horizontally fixed to the bottom surface of the fixed base plate 3 by a bracket. A through hole (with a diameter slightly larger than the air blowing pipe 11) is provided in the middle of the horizontal section to allow the air blowing pipe 11 to pass through. The vertical section (upper side) of the L-shaped exhaust pipe 12 extends upward and the top end is connected to the air inlet of the blower 13 by a flange.

[0074] After the heat melting is completed, the sliding table lifting mechanism drives the air blowing pipe 11 to move upward, so that the air outlet 111 at the lower end enters the horizontal section of the L-shaped exhaust pipe 12; the blower 13 is started to draw away the residual hot air in the air blowing pipe 11 to prevent the hot air from leaking out.

[0075] Housing 31: Used to cover the hot melt blowing part of the device to prevent operators from contacting high-temperature components; Housing 31 is installed on the mounting base (mounting side plate 2 and fixed base plate 3) by screws, and its interior covers the heater 10 of the hot melt actuator, the air guide tube, the blowing pipe 11 and the L-shaped exhaust pipe of the exhaust assembly. Heat dissipation holes are opened on the side of Housing 31 and the top is reserved for the installation port of blower 13.

[0076] Specifically, the working process of this utility model is as follows:

[0077] Feeding: The toy head 1 with the hair finished is put on the outside of the semi-circular support mouth 24 of the spreading mechanism 14 by manual or robotic means (at this time, the tensioning part 23 is in the closed state).

[0078] Connecting hole opening: Activate the opening cylinder 26, its air rod pushes the opening member 27 into the support groove 22, the wedge-shaped opening structure 28 squeezes the arc-shaped support surface 29 of the tension member 23, so that the two tension members 23 can rotate freely to the side outward, and the semi-circular support nozzle 24 opens the connecting hole of the toy head 1.

[0079] Toy head support: Support cylinder 17 drives support plate 18 to extend below toy head 1, and lifting cylinder 16 drives support plate 18 to move upward to lift the bottom of toy head 1.

[0080] Hot melt blowing: The electric slide table 4 drives the slide 5 to move downward, causing the blowing tube 11 to pass through the semi-circular insertion hole 25 and extend into the connection hole of the toy head 1; the heater 10 is powered on and heats up, and the hot air enters the blowing tube 11 through the air guide tube and is blown out from the large air outlet 111; at the same time, the rotating motor 6 is started, and drives the rotating shaft 7 and the blowing tube 11 to rotate through the synchronous belt pulley assembly, so as to achieve uniform hot melt of hair.

[0081] Hot air extraction: After the hot melting is completed, the electric slide table 4 drives the air blowing pipe 11 to move upward, so that the large air outlet 111 enters the L-shaped exhaust pipe 12; the blower 13 is started to extract the residual hot air.

[0082] Material removal and unloading: Support cylinder 17 drives support plate 18 to retract; lifting cylinder 16 drives unloading cylinder 19 to move upward, unloading cylinder 19 drives unloading plate 20 to extend, unloading hole fits to toy head 1; lifting cylinder 16 drives unloading plate 20 to move downward, toy head 1 slides from unloading hole opening into unloading channel, completing one cycle.
