Description

Technical Field

[0001] This utility model relates to the field of injection molding granulation equipment technology, and in particular to a single-screw extrusion injection molding quick connection device for artificial flowers of the Rosaceae family. Background Technology

[0002] A single-screw extruder consists of an Archimedes screw rotating in a heated barrel; it comprises five main parts: a drive system, a screw, a barrel, a heating and cooling system, and a control system. Its working principle is as follows: during rotation, the screw conveys solid plastic granules forward, which are melted and plasticized in the compression section, and then quantitatively extruded into the die through the homogenization section.

[0003] In plastic extrusion processing, single-screw extruders are typically connected to the die using flange bolts. This traditional method requires manual tightening of each bolt, which can take more than 30 minutes and relies on the operator's experience to ensure a tight seal. Frequent die changes can easily lead to material leakage or die misalignment due to uneven bolt preload, affecting the dimensional accuracy of the finished product. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a single-screw extrusion injection molding quick connection device for Rosaceae artificial flowers. This device utilizes the attraction between electromagnetic material A and electromagnetic mechanism B to drive the injection head towards the mold inlet and press the injection head and mold together, thereby connecting the single-screw extruder and the mold cavity. A return spring drives the injection head to automatically detach from the mold, thus quickly connecting the single-screw extruder and the mold. This device is simple, efficient, safe, reliable, and easy to operate.

[0005] This utility model is achieved through the following technical solution: a quick connection device for single-screw extrusion injection molding of artificial flowers of the Rosaceae family is provided, including a fastening mechanism fixed on the base of the mold, with an electromagnetic material A at one end of the fastening mechanism near the mold; a guide rod perpendicular to the mold is provided on the fastening mechanism, and an injection head perpendicular to and adapted to the mold inlet is slidably mounted on the guide rod, and the injection head is connected to the outlet of the single-screw extruder through a conveying pipe; the injection head is connected to the fastening mechanism through a return spring, and an electromagnetic mechanism B is provided on the injection head; the injection head is driven to move toward the mold inlet by the attraction between the electromagnetic material A and the electromagnetic mechanism B, and the injection head and the mold are pressed together, thereby connecting the single-screw extruder and the inner cavity of the mold; the injection head is automatically disengaged from the mold by the return spring, thereby quickly connecting the single-screw extruder and the mold.

[0006] As an optimization, the fastening mechanism includes a bracket with a groove extending radially along the bracket. A clamping arm slides within the groove, and a slider is hinged to the clamping arm via a transmission rod. The slider is slidably mounted on the bracket. The bracket has a fastening ring connected to the slider, and the bracket has a thread A. The fastening ring has a thread B that matches thread A. The fastening ring drives the slider to slide on the bracket, and the slider drives the clamping arm to slide within the groove via the transmission rod, thereby fixing the bracket to the base under the action of the clamping arm.

[0007] As an optimization, the bracket is provided with several protrusions A extending along the bracket axis, and thread A is located on protrusion A; a groove is formed between adjacent protrusions A, and a protrusion B that matches the groove is provided in the fastening ring, and thread B is located on protrusion B; the fastening ring can slide quickly on the bracket through the groove and protrusion B, and the bracket and the fixing ring are fixedly connected by the thread A on protrusion A and the thread B on protrusion B, thereby quickly connecting the bracket to the base.

[0008] As an optimization, the slider is connected by a compression spring and a fastening ring; the compression spring applies a certain pressure to the slider, and the slider applies a certain force to the clamping arm through the transmission rod, so that the clamping arm and the base bracket fit tightly together and prevent the clamping arm from loosening.

[0009] As an optimization, the grooves are evenly arranged around the axis of the bracket; the clamping arms, which are evenly arranged around the axis of the bracket, apply a uniform clamping force to the base.

[0010] As an optimization, an anti-slip pad is provided at the end of the clamping arm facing the base; the anti-slip pad prevents the clamping arm from sliding.

[0011] As an optimization, the mold can be made of electromagnetic material B, and electromagnetic material A can be made of electromagnetic mechanism A; by controlling the connection and disconnection between the mold and the support through electromagnetic mechanism A and electromagnetic material B, it is easy to quickly connect and replace the mold.

[0012] The beneficial effects of this utility model are as follows: The electromagnetic material A and electromagnetic mechanism B attract and drive the injection head towards the mold inlet, pressing the injection head and mold together, thus connecting the single-screw extruder and the mold cavity; the return spring drives the injection head to automatically detach from the mold, quickly connecting the single-screw extruder and mold; the groove and protrusion B allow the fastening ring to slide quickly on the bracket, which in turn drives the slider to slide on the bracket. The slider, via a transmission rod, drives the clamping arm to slide within the groove. The threads A on protrusion A and B on protrusion B secure the bracket and the fixing ring together, quickly connecting the bracket to the base; a compression spring applies pressure to the slider, which in turn applies force to the clamping arm via the transmission rod, ensuring a tight fit between the clamping arm and the base bracket, preventing loosening; the electromagnetic mechanism A and electromagnetic material B control the connection and disconnection between the mold and the bracket, facilitating quick mold connection and replacement.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figure 1 and 2 The single-screw extrusion injection molding quick connection device for Rosaceae artificial flowers shown in this utility model includes a fastening mechanism 1 fixed on the base 11 of the mold 10. An electromagnetic material A2 is provided at one end of the fastening mechanism 1 near the mold 10. A guide rod 3 is provided on the fastening mechanism 1, which is perpendicular to the mold 10. An injection head 4 is slidably mounted on the guide rod 3, which is perpendicular to the feed port of the mold 10 and adapted to the feed port. The injection head 4 is connected to the discharge port of the single-screw extruder 9 through a conveying pipe 5. The injection head 4 is connected to the fastening mechanism 1 through a return spring 6, and an electromagnetic mechanism B7 is provided on the injection head 4.

[0020] The injection head 4 is connected to the discharge port of the single screw extruder 9 through the feed pipe 5. The guide rod 3 is fixed to the base 11 of the mold 10 through the fastening mechanism 1. When the electromagnetic mechanism B7 is activated, the electromagnetic material A2 and the electromagnetic mechanism B7 attract each other. Under the action of the electromagnetic mechanism B7, the injection head 4 slides towards the mold 10 on the guide rail. The return spring 6 retracts until the port of the injection head 4 enters the feed port of the mold 10. The discharge port of the single screw extruder 9 is connected to the feed port of the mold 10 through the feed pipe 5 and the injection head 4.

[0021] When mold 10 needs to be replaced, the electromagnetic mechanism B7 is turned off, the return spring 6 is relaxed, and the injection head 4 slides on the guide rail away from mold 10 under the action of the return spring 6 until the injection head 4 disengages from mold 10, thereby quickly replacing mold 10.

[0022] like Figures 1-3 The fastening mechanism 1 shown includes a bracket 101. A groove extending radially along the bracket 101 is provided on the bracket 101. A clamping arm 102 is slidably disposed in the groove. A slider 104 is hinged to the clamping arm 102 via a transmission rod 103. The slider 104 is slidably sleeved on the bracket 101. A fastening ring 106 connected to the slider 104 is provided on the bracket 101. A thread A is provided on the bracket 101. A thread B that matches the thread A is provided on the fastening ring 106.

[0023] The bracket 101 has a cylindrical structure, and the sliding groove is located at the bottom of the bracket 101; the slider 104 has a ring-shaped structure, and the fastening ring 106 is sleeved on the bracket 101.

[0024] Rotate the fastening ring 106 on the bracket 101. The fastening ring 106 drives the slider 104 to slide on the bracket 101. The slider 104 drives the clamping arm 102 to slide in the groove through the transmission rod 103. Under the action of the clamping arm 102, the bracket 101 is fixed to the base 11.

[0025] like Figures 1-3 The bracket 101 shown has several protrusions A extending along the axial direction of the bracket 101, and thread A is located on the protrusion A; a groove is formed between adjacent protrusions A, and a protrusion B that matches the groove is provided in the fastening ring 106, and thread B is located on the protrusion B.

[0026] Pushing the fastening ring 106 causes it to slide rapidly on the bracket 101. The fastening ring 106 drives the slider 104 to slide on the bracket 101. The slider 104 drives the clamping arm 102 to slide in the groove through the transmission rod 103 until the bracket 101 is fixed to the base 11 under the action of the clamping arm 102. Rotating the fastening ring 106 causes threads A and B to engage with each other, fixing the bracket 101 and the fixing ring together. The bracket 101 is then fixed to the base 11 through the clamping arm 102.

[0027] When it is necessary to replace the mold 10 base 11, rotate the fastening ring 106, the threads A and B separate from each other, pull the fastening ring 106 outward, the fastening ring 106 slides on the bracket 101, the slider 104 loosens on the bracket 101, the clamping arm 102 loosens on the base 11, and the bracket 101 disengages from the base 11.

[0028] like Figures 1-3 The slider 104 shown is connected to the retaining ring 106 via a compression spring 105.

[0029] Pushing the fastening ring 106 causes it to slide rapidly on the bracket 101, compressing the spring 105.

[0030] When it is necessary to replace the mold 10 base 11, rotate the fastening ring 106, the threads A and B separate, the compression spring 105 relaxes, the fastening ring 106 slides on the bracket 101, the slider 104 loosens on the bracket 101, the clamping arm 102 loosens on the base 11, and the bracket 101 disengages from the base 11.

[0031] like Figures 1-3 The grooves shown are evenly arranged around the axis of the bracket 101.

[0032] like Figure 1 and Figure 2 The clamping arm 102 shown is provided with an anti-slip pad 8 at the end facing the base 11.

[0033] The clamping arm 102 drives the anti-slip pad 8 to move toward the base 11.

[0034] like Figure 1 and Figure 2 The mold 10 shown can be made of electromagnetic material B, and electromagnetic material A2 can be made of electromagnetic mechanism A; electromagnetic mechanism A and electromagnetic mechanism B7 attract each other.

[0035] When electromagnetic mechanism A is activated, electromagnetic mechanism A causes support 101 to adhere to mold 10.

[0036] When mold 10 needs to be replaced, turn off electromagnetic mechanism A and bracket 101 will disengage from mold 10.

[0037] In actual production, the injection head 4 is connected to the discharge port of the single screw extruder 9 through the feeding pipe 5, and the bracket 101 is placed on the base 11. Pushing the fastening ring 106, the fastening ring 106 slides quickly on the bracket 101, the compression spring 105 contracts, and the fastening ring 106 drives the slider 104 to slide on the bracket 101. The slider 104 drives the clamping arm 102 to slide in the groove through the transmission rod 103 until the bracket 101 is fixed to the base 11 under the action of the clamping arm 102. Rotating the fastening ring 106, the threads A and B are engaged with each other, the bracket 101 and the fixing ring are fixed together, and the bracket 101 is fixed to the base 11 through the clamping arm 102.

[0038] When electromagnetic mechanism A is activated, the support 101 is attracted to the mold 10. When electromagnetic mechanism B7 is activated, electromagnetic material A2 and electromagnetic mechanism B7 attract each other. Under the action of electromagnetic mechanism B7, the injection head 4 slides towards the mold 10 on the guide rail. The return spring 6 contracts until the port of injection head 4 enters the feed port of mold 10. The discharge port of single screw extruder 9 is connected to the feed port of mold 10 through the feed pipe 5 and injection head 4.

[0039] When mold 10 needs to be replaced, the electromagnetic mechanism B7 is turned off, the return spring 6 is relaxed, and the injection head 4 slides on the guide rail away from mold 10 under the action of the return spring 6 until the injection head 4 is removed from mold 10; the electromagnetic mechanism A is turned off, and the bracket 101 is removed from mold 10; thus, mold 10 can be replaced quickly.

[0040] When it is necessary to replace the mold 10 base 11, rotate the fastening ring 106, the threads A and B separate, the compression spring 105 relaxes, the fastening ring 106 slides on the bracket 101, the slider 104 loosens on the bracket 101, the clamping arm 102 loosens on the base 11, and the bracket 101 disengages from the base 11.
