Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, specifically to an injection molding machine for artificial plastic flowers and plants. Background Technology

[0002] Artificial flowers and plants refer to fake flowers and plants made of materials such as stretched silk, crepe paper, polyester, plastic, and crystal, as well as dried flowers and plants made from fresh flowers and plants. In the industry, they are generally referred to as artificial flowers and plants. As the name suggests, artificial flowers and plants are modeled after real flowers and plants and are imitated using materials such as cloth, gauze, silk, and plastic. Because artificial flowers and plants often come in a variety of colors, different colors of plastic particles need to be used for injection molding for different batches during production.

[0003] Chinese patent CN112454813B discloses a color mixing injection unit and an injection molding machine. The color mixing injection unit includes an injection unit base, a sliding base plate, a main injection unit mechanism, a secondary injection unit mechanism, a moving cylinder mechanism, a flange connector, a color mixing mechanism, and a nozzle. The sliding base plate is slidably connected to the injection unit base. The main injection unit mechanism and the secondary injection unit mechanism are fixed on the sliding base plate, and their discharge ends are respectively connected to the flange connector. The included angle between the horizontal projections of the main injection unit mechanism and the secondary injection unit mechanism is less than 90 degrees. The moving cylinder mechanism is used to drive the sliding base plate to slide back and forth along the injection unit base. The color mixing mechanism is disposed in the flange connector. The discharge ends of the main injection unit mechanism and the secondary injection unit mechanism are respectively connected to the feed end of the color mixing mechanism. The nozzle is connected to the discharge end of the color mixing mechanism.

[0004] This color mixing injection station only mixes materials through the main injection station mechanism and the auxiliary injection station mechanism. The mixed colors are limited and it is not suitable for injection molding of plastic flowers and plants. That is, the mixing of two colored plastic melts can only produce simulated flowers and plants of one color. Therefore, it is necessary to change the colored plastic melts multiple times, resulting in a long production cycle. Summary of the Invention

Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the present invention provides:

[0032] A special injection molding machine for plastic flowers and artificial plants includes a converging injection mechanism. The converging injection mechanism includes a color mixing component 1, an injection nozzle 2, and at least three feeding components 3. The color mixing component 1 is connected to the feeding components 3 to mix molten material. The injection nozzle 2 is disposed on the color mixing component 1 for injecting the mixed molten material into the mold. The color mixing component 1 includes a color mixing table 11, a rotating guide 12, and a rotating drive 13. The color mixing table 11 has a placement cavity and a color mixing cavity. The feeding tube of the feeding component 3 extends into the placement cavity. The rotating guide 12 is rotatably disposed in the placement cavity. The rotating guide 12 has a first material channel that can connect any two feeding components 3 and the color mixing cavity when rotating. The injection nozzle 2 is disposed on the color mixing table 11 and communicates with the color mixing cavity. The rotating drive 13 is disposed on the color mixing table 11 and is drively connected to the rotating guide 12.

[0033] In use, by activating the rotary drive 13, the rotary guide 12 can rotate in the mixing table 11. The first material channel on the rotary guide 12 can connect any two feeding components 3. Since there are at least three feeding components 3, the three feeding components 3 can be combined in three ways, thus producing three different colors of plastic melt. The colored plastic melt in the feeding component 3 enters the mixing chamber through the first material channel, so that the two colored plastic melts can be mixed in the mixing chamber, and then injected into the mold through the injection nozzle 2 to carry out production.

[0034] In this embodiment, by rotating the rotating guide 12, the first material channel on it can connect any two plastic feeding components 3 with the color mixing chamber, so that the two plastic feeding components 3 can inject colored plastic melt into the color changing chamber. Therefore, the color mixing table 11 can produce at least three kinds of plastic melt through the injection nozzle 2, which facilitates the production of artificial flowers and plants of different colors. This solves the problem that existing color mixing injection tables need to frequently change colored plastic raw materials when producing artificial flowers and plants, thereby reducing the production cycle and improving production efficiency.

[0035] like Figure 5 and Figure 6 As shown, the rotating guide 12 also has a second material channel 123 that can connect any one of the plastic feeding components 3 and the color mixing chamber when rotating.

[0036] Because a second material channel 123 is also provided on the rotary guide 12, when the rotary guide 12 rotates in the placement cavity, the second material channel 123 can connect the color mixing cavity and any one of the feeding components 3, so that the colored plastic melt in one feeding component 3 can be injected into the mold through the injection nozzle 2. Therefore, at least the feeding component 3 can produce at least six mixtures, thereby improving the variety of the injection mechanism.

[0037] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the rotary drive 13 includes a servo motor 14, a drive shaft 15, and a forward drive. The servo motor 14 is mounted on the mixing table 11. The drive shaft 15 passes through the mixing table 11 and the rotary guide 12 and extends into the mixing chamber. One end of the drive shaft 15 is connected to the servo motor 14. The forward drive is located between the rotary guide 12 and the drive shaft 15. The drive shaft 15 outputs a positive torque to the rotary guide 12 through the forward drive. The confluence injection mechanism also includes a stirring element 4 located in the mixing chamber. The stirring element 4 is fixedly connected to the other end of the drive shaft 15.

[0038] When it is necessary for the rotary guide 12 to rotate in the mixing table 11, the servo motor 14 is started, so that the servo motor 14 can drive the drive shaft 15 to rotate a certain angle in the mixing table 11. The drive shaft 15 is connected to the rotary guide 12 through a forward drive, so that when the drive shaft 15 rotates in the forward direction, the drive shaft 15 can input torque to the rotary guide 12, so that the rotary guide 12 can rotate in the placement cavity, thereby enabling the first material channel to connect any two plastic feeding components 3.

[0039] To improve the mixing efficiency of the two colored plastic melts in the mixing chamber, the servo motor 14 is started to drive the transmission shaft 15 to rotate in the opposite direction in the mixing table 11. The stirring element 4 is set at the bottom of the transmission shaft 15, so that the stirring element 4 rotates at high speed in the mixing chamber, thereby enabling the rotating stirring element 4 to improve the mixing efficiency of the two colored plastic melts in the mixing chamber.

[0040] like Figure 6 and Figure 7 As shown, the injection confluence mechanism also includes a reverse stop assembly, which is disposed between the rotating guide 12 and the mixing stage 11. The reverse stop assembly is used to prevent the rotating guide 12 from rotating in the reverse direction in the placement cavity.

[0041] To prevent the rotating guide 12 from rotating in the placement cavity when the drive shaft 15 rotates in the reverse direction in the mixing table 11, a reverse stop assembly is provided between the rotating guide 12 and the placement cavity, so that the rotating guide 12 cannot rotate in the reverse direction in the placement cavity, and the stirring component 4 can rotate at high speed in the mixing cavity when the drive shaft 15 rotates in the reverse direction.

[0042] like Figure 5 , Figure 6 and Figure 7As shown, the color mixing table 11 includes a first table body 111 and a first end cap 112. The first end cap 112 is provided with a first insertion port arranged circumferentially thereon. The first end cap 112 is disposed on the first table body 111. The plastic feeding tube of the plastic feeding assembly 3 is connected to the first insertion port. The rotating guide 12 is a rotating disk 124. The rotating disk 124 is coaxially rotatably disposed in the placement cavity. The rotating disk 124 is provided with a first channel 1242 and a second channel 1243 distributed circumferentially thereon. The first channel 1242 and the second channel 1243 form a first material channel for connecting any two plastic feeding assemblies 3 and the color mixing cavity. The second material channel 123 is disposed on the rotating disk 124.

[0043] As a first embodiment of the rotating guide 12 in this application, when the drive shaft 15 rotates in the forward direction, it can drive the rotating disk 124 to rotate a certain angle in the placement cavity through the forward transmission device. The rotating disk 124 is provided with a first channel 1242 and a second channel 1243, so that when the rotating disk 124 rotates, the first channel 1242 and the second channel 1243 can be connected to any two plastic feeding components 3 respectively. The first channel 1242 and the second channel 1243 can communicate with the color mixing cavity, so that the two plastic feeding components 3 can feed the colored plastic melt into the color mixing cavity to produce the mixed color melt.

[0044] like Figure 5 , Figure 6 and Figure 7 As shown, the forward transmission includes a first fixed disk 161, a first pawl 162, and a spring plate 163. The top of the rotating disk 124 is provided with a circular groove. The first fixed disk 161 is coaxially rotatably disposed in the circular groove. The first fixed disk 161 is coaxially fixedly connected to the transmission shaft 15. A first ratchet groove 1241 is provided on the circumferential surface of the circular groove and arranged circumferentially thereon. The first pawl 162 is rotatably disposed on the first fixed disk 161. A retainer is provided on the first fixed disk 161. The spring plate 163 is disposed between the retainer and the first pawl 162. The first pawl 162 elastically abuts against the first ratchet groove 1241.

[0045] Because the first pawl 162 abuts against the first ratchet groove 1241 under the action of the spring plate 163, when the drive shaft 15 rotates forward in the mixing table 11, the first pawl 162 abuts against the stop side of the first ratchet groove 1241, so that the first fixed plate 161 can drive the rotating plate 124 to rotate in the placement cavity, thereby connecting the first material channel with any two feeding components 3. When the drive shaft 15 rotates in reverse in the mixing table 11, the first pawl 162 overcomes the elastic force of the spring plate 163 and slides on the inclined surface of the first ratchet groove 1241, so that the first fixed plate 161 can rotate in the circular groove, thereby preventing the drive shaft 15 from driving the rotating plate 124 to rotate when rotating in reverse.

[0046] like Figure 7 As shown, the bottom end of the first end cap 112 is provided with a second ratchet groove 1121 distributed circumferentially thereon, and the top end of the rotary disk 124 is provided with a first mounting groove distributed axially thereon. The reverse stop assembly includes a second pawl 51 and a first spring 52. The second pawl 51 is slidably disposed in the first mounting groove along the longitudinal direction, and the first spring 52 is disposed at the bottom end of the second pawl 51. The second pawl 51 elastically abuts against the second ratchet groove 1121.

[0047] To ensure that the rotating disk 124 can only rotate in the forward direction within the mounting cavity, a second ratchet groove 1121 is provided at the bottom end of the first end cover 112, distributed circumferentially. The second pawl 51 abuts against the second ratchet groove 1121 under the action of the first spring 52, so that when the first fixed disk 161 rotates in the forward direction, the second pawl 51 abuts against the stop side of the second ratchet groove 1121; when the first fixed disk 161 rotates in the reverse direction, the second pawl 51 overcomes the elastic force of the first spring 52 and slides on the inclined surface of the second ratchet groove 1121, so that the rotating disk 124 cannot rotate in the reverse direction.

[0048] like Figure 9 , Figure 10 and Figure 11 As shown, the color mixing table 11 includes a second platform body 113 and a second end cap 114. The second platform body 113 is provided with a second insertion port arranged along its axial direction. The second end cap 114 is disposed at one end of the second platform body 113. The plastic feeding tube of the plastic feeding assembly 3 is connected to the second insertion port. The rotating guide 12 is a rotating cylinder 125. The rotating cylinder 125 is coaxially rotatably disposed in the placement cavity. The drive shaft 15 passes through the end cap and is connected to the rotating cylinder 125 for transmission. The rotating cylinder 125 is provided with a first double channel 1251, a second double channel 1252 and a third double channel 1253. The first double channel 1251, the second double channel 1252 and the third double channel 1253 form a first material channel for connecting any two plastic feeding assemblies 3 and the color mixing cavity. The second material channel 123 on the rotating cylinder 125 can correspond one-to-one with the plastic feeding assembly 3.

[0049] As a second embodiment of the rotating guide 12 in this application, by rotatably setting the rotating cylinder 125 in the placement cavity, when the servo motor 14 drives the rotating cylinder 125 to rotate in the placement cavity, when the first double channel 1251, the second double channel 1252 and the third double channel 1253 can connect any two feeding components 3, the first double channel 1251, the second double channel 1252 and the third double channel 1253 can inject two colored plastic melts into the rotating cylinder 125 individually, and at the same time the stirring component 4 can mix the melts in the rotating cylinder 125, so that the mixed colored melts can be injected into the mold through the injection nozzle 2.

[0050] like Figure 9 and Figure 10 As shown, the forward drive includes a closed disc 164, a fixed cylinder 165, a second fixed disc 166, a third pawl 167, and a second spring 168. The closed disc 164 is fixedly disposed at one end of the rotating cylinder 125, and the fixed cylinder 165 is coaxially fixedly disposed at one end of the closed disc 164. A third ratchet groove 1651 distributed circumferentially therein is provided on the inner circumferential surface of the fixed cylinder 165. The second fixed disc 166 is coaxially fixedly disposed on the drive shaft 15. A second mounting groove extending radially therein is provided on the circumferential surface of the second fixed disc 166. The third pawl 167 is slidably disposed in the second mounting groove. The second spring 168 is disposed at one end of the third pawl 167 near the axis of the second fixed disc 166. The third pawl 167 elastically abuts against the third ratchet groove 1651.

[0051] Because the second fixed disk 166 is fixedly mounted on the drive shaft 15, the third pawl 167, under the action of the second spring 168, abuts against the second pawl 51 radially. When the drive shaft 15 rotates forward in the mixing table 11, the third pawl 167 abuts against the stop side of the third pawl 167, so that the drive shaft 15 can transmit torque to the closed disk 164, so that the closed disk 164 can rotate in the mixing table 11, and thus the rotating cylinder 125 can rotate in the mixing table 11. When the drive shaft 15 rotates in the reverse direction, the third pawl 167 overcomes the elastic force of the second spring 168 and slides on the inclined surface of the third pawl 167, thereby preventing the torque of the drive shaft 15 from being transmitted to the fixed cylinder 165, so that the reverse-rotating drive shaft 15 can drive the stirring component 4 to rotate in the rotating cylinder 125.

[0052] like Figure 9 and Figure 10As shown, the outer circumferential surface of the fixed cylinder 165 is provided with a fourth ratchet groove 1652 distributed along its circumference. The reverse stop assembly includes a fourth pawl 53 and a third spring 54. The inner wall of the mounting cavity is provided with a third mounting groove. The opening direction of the third mounting groove is parallel to the radial direction of the second fixed disk 166. The fourth pawl 53 is slidably disposed in the third mounting groove. The third spring 54 is disposed at one end of the fourth pawl 53 away from the axis of the second fixed disk 166. The fourth pawl 53 elastically abuts against the fourth ratchet groove 1652.

[0053] The fourth pawl 53 abuts against the fourth ratchet groove 1652 under the action of the third spring 54. When the drive shaft 15 rotates in the forward direction, the fourth pawl 53 overcomes the elastic force of the third spring 54 and slides on the inclined surface of the fourth ratchet groove 1652, thereby enabling the rotating cylinder 125 to rotate in the forward direction. When the drive shaft 15 rotates in the reverse direction, the fourth pawl 53 abuts against the stop side of the fourth ratchet groove 1652, preventing the rotating cylinder 125 from rotating in the mixing table 11, thereby enabling the stirring component 4 to rotate in the rotating cylinder 125.

[0054] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
