DETAILED DESCRIPTION

[0026] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0028] Embodiment one

[0029] As shown in the drawings, in the present embodiment, an inner plastic process method suitable for the modeling of a simulation doll is mainly disclosed. It should be noted that the inner plastic process method in the present embodiment is suitable for the modeling of the head and body of all simulation dolls, and is not limited to the head of a plush toy. Since in actual products, the three-dimensional modeling difficulty of the head is greater than that of the body, in the present embodiment, the head is taken as an example for description. Figure 1 Specifically, the following steps are included:

[0030] S1: draw the wiring path 1, the needle insertion angle, and the pull wire length on the cloth according to the modeling of the head; for example, as shown in the drawings, for the modeling of a doll cat, the three-dimensional modeling wiring path 1 of the eyes, nose, and mouth of the doll cat is drawn in advance on the cloth to be used. The pull wire and the filler 2 are matched through the wiring path 1 to realize the bulging and concave of the face and complete the modeling.

[0031] Figures 1-3

[0032] ​​S2: the cloth package filling 2, the needle is inserted into the inside of the head from different angles of the wiring path 1, hooks on the inside plastic pull wire device 3, and then goes out, changes the shape of the head by the length of the pull wire, and constructs the image of the five senses; standardize the production process and increase the production efficiency.

[0033] It should be noted that in the embodiment, the wiring path 1, the needle insertion angle and the pull wire length are drawn in advance, which can be achieved by the following means: the wiring path 1 is drawn on the cloth in the form of a line, the needle insertion angle is drawn in the form of a number, for example, 1 in the tens place represents 15°; 2 in the tens place represents 30°, and the angle between the tens digit 1 and the wiring path 1 is the angle of needle insertion. In addition, the length of the pull wire is also represented by numbers, for example: 1 in the units place represents that the pull wire needs to be retained 3 cm relative to the inside plastic pull wire device 3; 2 in the units place represents that the pull wire needs to be retained 6 cm relative to the inside plastic pull wire device 3; and the length is marked on the pull wire with a color mark for easy observation. Therefore, through the marking 11 or 21, the operator can be prompted about the stitching method at this position, 11 represents 15° and the pull wire is retained 3 cm, 21 represents 30° and the pull wire is retained 3 cm, and by observing the angle between 11 or 21 and the wiring path 1, the operator can know how to insert the needle; the positioning of the needle insertion is achieved by the angle, length, needle insertion point and positioning of the inside plastic pull wire device 3; it should be noted that for the cloth with markings, the inside and outside double-layer cloth can be used for covering in the later stage, for example, the inside cloth mainly uses cloth with small elasticity as the modeling cloth, and the outside cloth uses velvet as the decorative cloth, or the needle hiding method is used to hide the marked points; this is not limited.

[0034] In the embodiment, as shown in Figure 4 The inside plastic pull wire device 3 is arranged inside the head, which includes a fixed part 4 and a plurality of extension parts 5 arranged on the fixed part 4, the extension parts 5 are scattered around the fixed part 4 to connect the pull wire, for example, two longer extension parts 5 can be arranged to connect the pull wire for the eyes, and a short pull wire can be arranged for the nose to meet the demand, in order to ensure the fixation of the pull wire, the end of the extension part 5 is provided with a limiting part for connecting the pull wire.

[0035] Further explanation of the inner plastic process in the embodiment, in the embodiment, the needle is penetrated from the outside of the head, and then the line is hung on the inner plastic pulling line device 3 or the limiting part by using the flexibility of the line. Since the inner plastic pulling line device 3 is fixed, the depth of the three-dimensional modeling can be adjusted by pulling the line. The bulge of the eyeball or the nose tip is realized by using the foam or the PP cotton as the filler 2, so as to construct the three-dimensional modeling. The height of the bulge of different modeling can be realized by different additives. The hidden suture method can be used for the suture. In addition, for the fixation of the inner plastic pulling line device 3, no special requirement is needed, and the existing technology can be used for fixation. Here, two implementation methods are given. 1: The inner member fixing frame of the simulation doll is fixed. The fixing frame is distributed in the limbs, the trunk and the head, and the inner plastic pulling line device 3 is fixed on the fixing frame. 2: The fixing rod 23 is arranged on the organs such as the ears and the nose to fix the inner plastic pulling line device 3. Of course, the number of the extension pieces 5 can be reduced at the organs where the fixing rod 23 is arranged.

[0036] Embodiment two

[0037] In the embodiment, the main structure is completely consistent with that of the embodiment one, and the difference lies in that in the embodiment, an inner plastic device suitable for the modeling of the simulation doll is disclosed to further optimize the inner plastic modeling. Specifically, the filler 2 adopts the micro air bag or the micro air bag+PP cotton mode. The advantage of this mode is that in the later use process of the simulation doll, whether it is pp cotton, sponge, foam, velvet, artificial chemical fiber, cotton or the like, the phenomenon of sinking will occur, resulting in uneven toys. The micro air bag has the advantage that the sinking place can be supported by the inflation mode in the later period, so that the toy is full. It needs to be explained that the micro air bag can be arranged as one air bag layer to realize, or a plurality of micro air bags are separately used, such as the eyes which can be arranged as the filler 2 in the mode of cooperating with the pp cotton. The micro air bag is connected with the gas supply device, and the micro air bag is inflated at any time to construct the three-dimensional modeling. Of course, the volume of the micro air bag is not limited, and the material is made of high elasticity material.

[0038] Generally, the micro air bags at one organ are connected with each other, and then the gas supply device is separately connected. For the body and the limbs of the simulation doll, the air bag cooperating with the pp cotton mode can also be used to realize the inflation in the later period.

[0039] In the embodiment, the micro inflator 6 is used as the air supply device, and the micro inflator 6 is arranged in the interior of the fixing member 4 which is in a cylindrical shape, and the micro inflator 6 comprises a piston rod, a first one-way valve and a second one-way valve; the interior of the fixing member 4 is provided with a baffle, and the baffle is provided with the first one-way valve; the end of the piston rod is provided with a first piston which is sealingly and slidingly arranged in the interior of the fixing member 4; the first piston is provided with the second one-way valve; the first one-way valve is communicated with the micro air bag; the first one-way valve, the second one-way valve, the piston rod and the fixing member 4 form a micro inflator, and the air supply to the micro air bag can be completed by reciprocating the piston rod, and since the micro inflator 6 is arranged in the interior of the fixing member 4, the second one-way valve will not be blocked by the pp cotton and the like.

[0040] Embodiment three

[0041] In the embodiment, the main structure is consistent with that of the second embodiment, and the difference lies in that, in the embodiment, the air supply is not performed by reciprocating the inflator, and since the air supply process in the second embodiment requires that the user holds the inner plastic pull wire device 3 by one hand through the cloth and reciprocally pushes and pulls the piston rod by the other hand to complete the air supply work, one forward and reverse stroke results in complicated operation and is not easy to control, and since the whole device is arranged in the interior of the tire head, the intermittent pushing force and pulling force to the inner plastic pull wire device 3 can result in the pull wire falling off, which is not conducive to the long-time keeping of the three-dimensional modeling.

[0042] In the embodiment, the air supply work is completed by one direction stroke, and specifically, as shown in Figure 5 and Figure 6 , the interior of the fixing member 4 is fixedly provided with a positioning rod 7 which is a round rod, and the positioning rod 7 is coaxially arranged with the fixing member 4; the micro inflator 6 comprises, arranged in the interior of the fixing member 4 from inside to outside: an arc-shaped inflator 8, a first driving circular plate 10, a turning plate 11, a second driving circular plate 12 and a manual plate 16;

[0043] The arc-shaped inflator 8 is fixedly arranged on the positioning rod 7, and specifically, the arc-shaped inflator 8 is fixedly arranged with the positioning rod 7 as the center axis, the interior of the arc-shaped inflator 8 is provided with an arc-shaped piston rod 9, the arc-shaped piston rod 9 is sealingly and slidingly connected in the interior of the arc-shaped inflator 8 through a second piston, the second piston is provided with a third one-way valve, the outlet of the arc-shaped inflator 8 is provided with a fourth one-way valve, and the fourth one-way valve is communicated with the micro air bag;

[0044] The first driving circular plate 10 is rotatably arranged on the positioning rod 7 through a bearing, the first driving circular plate 10 is provided with four first magnets 13, the first magnets 13 are in the shape of circular sheet, and the front and back surfaces of the four first magnets 13 are staggered arranged, so as to realize the staggered arrangement of the front and back surfaces; it is to be noted that the four first magnets 13 are uniformly distributed on the circumference with the positioning rod 7 as the center axis, so the distance between the adjacent first magnets 13 is 90 degrees.

[0045] The steering plate 11 is rotatably mounted on the positioning rod 7 via a bearing. The steering plate 11 is provided with 10 metal rods 15, which can be made of iron screws. The 10 metal rods 15 are distributed throughout the steering plate 11 and are evenly distributed on the circumference with the positioning rod 7 as the central axis.

[0046] The second drive circular plate 12 is rotatably mounted on the positioning rod 7 via bearings. The second drive circular plate 12 is provided with 12 second magnets 14, with the positive and negative sides of the second magnets 14 arranged alternately. Similarly, the second magnets 14 are circular plate magnets, with the positive and negative sides of the second magnets 14 alternating. In addition, since there are 12 second magnets 14 and they are all evenly distributed on the circumference with the positioning rod 7 as the central axis, and the radii of the first magnet 13 and the second magnet 14 around the positioning rod 7 are the same, the radius of the second magnet 14 is smaller than the radius of the first magnet 13.

[0047] The manual plate 16 is rotatably mounted on the positioning rod 7 via a bearing; the manual plate 16 has a slide groove 17 on the side facing the second drive circular plate 12, and a slide 18 is provided between the manual plate 16 and the second drive circular plate 12. A first transmission rod 19 is vertically mounted on the left end of the slide 18, and a second transmission rod 20 is vertically mounted on the right end of the slide 18. Figure 7 As shown, the slide 18 has a sliding hole 21 in the middle, which is fitted onto the positioning rod 7. One end of the first transmission rod 19 is slidably connected to the manual plate 16 through the sliding groove 17. Specifically, a dovetail groove can be used for the connection. One end of the second transmission rod 20 is slidably connected to the manual plate 16 through the sliding groove 17. A dovetail groove can also be used for the connection. Specifically, the slide 18 can slide on the manual plate 16. The sliding hole 21 prevents the positioning rod 7 from affecting the sliding. The fixing member 4 has a protrusion 22 inside. The protrusion 22 abuts against the first transmission rod 19 / second transmission rod 20. The length of the protrusion 22 is a and it is set around the positioning rod 7. π / 2≤a<π. In this embodiment, if the first transmission rod 19 and the second transmission rod 20 are considered as a line, then the length of the protrusion 22 is π. Of course, in other embodiments, π / 2 can be used.

[0048] The other end of the first transmission rod 19 is used to drive the first driving circular plate 10 to rotate, and the other end of the second transmission rod 20 is used to drive the second driving circular plate 12 to rotate; the first driving circular plate 10 is connected to the arc-shaped piston rod 9. Here, there is no restriction on the way the first transmission rod 19 drives the first driving circular plate 10 to rotate. For example, the flange of the first driving circular plate 10 is provided with several rectangular teeth, and the first transmission rod 19 achieves drive by sliding and engaging the rectangular teeth; the second transmission rod 20 is similar; it should also be noted that in this embodiment, the operator only needs to rotate the manual plate 16. The manual plate 16 can be equipped with a handle, and the operator can control the rotation of the handle by the fabric, or the fabric can be set to be openable by Velcro.

[0049] The entire process is as follows:

[0050] First half: Manually controlled manual plate 16 rotates around positioning rod 7, driving slide 18 to rotate around positioning rod 7. The right end of slide 18 abuts against protrusion 22 on fixing member 4 and then slides in the opposite direction, causing second transmission rod 20 to contact second drive plate 12 and rotate. After second drive plate 12 rotates 180°, as... Figure 8 As shown, the magnetic field linear density formed by the 12 second magnets 14 is greater than that formed by the 4 first magnets 13. Due to the presence of the iron screw, and the principle of opposite poles attracting and like poles repelling, the second magnets 14 will drive the first magnets 13 to rotate in the opposite direction. Simultaneously, due to the 12:4 ratio, the rotational speed of the first magnets 13 is three times that of the second magnets 14. Therefore, when the second driving plate 12 rotates by π / 2, theoretically the first driving plate 10 should rotate by -540°, but due to the limit, it will only rotate by -180°. If the length of the protrusion 22 is π / 2, then the rotation angle of the first driving plate 10 is -270°, exactly achieving 270°. +90°, forming a circle; since the first driving circular plate 10 is fixedly connected to the arc-shaped piston rod 9, the longest movement angle of the arc-shaped piston rod 9 is 180° (the arc-shaped piston rod 9 and the arc-shaped air cylinder 8 each divide a circle, each 180°, which is not necessary; the length of the arc-shaped piston rod 9 can be appropriately reduced and the length of the arc-shaped air cylinder 8 increased to meet the usage requirements; the maximum movement range is π / 2), so the first driving circular plate 10 drives the arc-shaped piston rod 9 to move π / 2. It should be emphasized that the rotation direction of the first driving circular plate 10 is opposite to the rotation direction of the manual plate 16; thus realizing the pull-out of the arc-shaped piston rod 9, and at the same time, the 3 times movement speed can ensure that the arc-shaped piston rod 9 moves to the position.

[0051] In the second half: the manual plate 16 continues to rotate around the positioning rod 7, and the manual plate 16 drives the slide 18 to rotate around the positioning rod 7. After the left end of the slide 18 abuts against the protrusion 22 set on the fixing part 4, it will slide in the opposite direction, so that the first transmission rod 19 will contact the first driving plate 10 and start to rotate. The first driving plate 10 rotates 180°; and drives the arc piston rod 9 to rotate 180° to realize inflation. During this process, the second driving plate 12 will move a distance of π / 6.

[0052] It is worth emphasizing that, in order to ensure the normal operation of the movement, the diameter of the steering plate 11 is smaller than the diameter of the second drive plate 12, which is smaller than the diameter of the first drive plate 10. In addition, in some embodiments, the micro inflation device 6 can be set inside the tire body, with an appropriate increase in volume to improve inflation efficiency. The first magnet 13 and the second magnet 14 can both be permanent magnets.

[0053] The whole process only needs the operator to rotate along one rotation direction, and the forward movement (inflation) and reverse movement (suction) of the arc-shaped piston rod 9 can be realized by cooperating with the first one-way valve and the second one-way valve, so that the micro air bag is inflated, and meanwhile, the device in the embodiment is flat, and the size is smaller than that of a traditional inflator, and is more suitable for small equipment such as a simulation doll.

[0054] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
