Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a continuous feeding device for injection molding of air conditioner plastic accessories. Background Art

[0002] The air-conditioning shell refers to the PVC shell structure at the air outlet end of the air-conditioning interior chassis. In the existing technology, the injection molding of air-conditioning shells faces some challenges, especially in the continuous injection of the processing. The traditional injection stage has difficulties in achieving a continuous supply of raw materials, resulting in the inability to achieve a unified material supply of PVC particles of different types and qualities. In addition, in the existing technology, the buzzer plastic shell injection molding machine equipment can collect the plastic shell after injection molding through the set guide plate, and it is convenient to connect with other equipment to send the collected injection mold to the next process, thereby improving the practicality of the device. However, this equipment is not efficient in the injection molding of plastic shells, and cannot achieve a unified supply of PVC particles of different types and qualities, which limits the production efficiency and flexible use of materials.

[0003] Chinese patent CN219276480U discloses a continuous feeding device for the injection molding of air conditioner casings. This device utilizes a comprehensive continuous feeding mechanism to achieve automated and continuous injection molding of air conditioner casings. The device comprises a processing mechanism supported by a convex base plate. A processing tank is located in the middle of the top of the base plate for mixing and blending materials. The bottom end of the processing tank is sealed with a connecting valve via a conical discharge port. An electromagnetic feeder is installed at the bottom of the connecting valve to control the flow of materials. Below the electromagnetic feeder is a placement plate connected to the central support of the convex base plate. The top of the processing tank is covered by an upper cover, which houses a batching mechanism. This mechanism uses connecting openings and inlet pipes to heat-melt plastic granules of varying proportions in a classified manner. The melted materials are then introduced into the processing tank via an arc-shaped pipe. The batching mechanism also includes a storage sleeve and a filter sleeve. The filter sleeve houses a mixing and rotating feeder for mixing the materials. In addition, a mini-mixing mechanism is located behind the convex baseplate, consisting of a processing support, placement slots, a tapered injection sleeve, and a material processing sleeve. The material processing sleeve has an injection sleeve at the top and a cover at the bottom. The cover has an upper cover in the middle of its bottom end, connected to a connecting tube at the middle of its bottom end, for temporary material storage and sorting. The middle of the bottom end of the connecting tube is connected to the processing support via a connecting base. A mixing extraction pipe is located at the bottom, connected to the outside world via a blower for material screening and feeding. The other end of the processing tank is connected via a hose to a feeding mechanism consisting of an L-shaped placement rack, a blower, a storage tank, and a controller for sorting and conveying different types of materials. A PVC granular storage cabinet is located next to the storage tank, and an external frame is located in the middle of its bottom end for material management and storage. The coordinated operation of these structures enables continuous material feeding during the injection molding of air conditioner casings, improving production efficiency and material flexibility.

[0004] The processing mechanism in this patent document needs to be connected to multiple devices through pipes, and it is a split design. Each time the pipe is connected, it must be plugged and unplugged. Multiple plugging and unplugging processes may cause loosening, which may cause the contents of the processing equipment to leak out. In addition, when some insertion ports are not connected to pipes, the internal processing space of the processing device may be connected to the external space. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1-6 A continuous feeding device for injection molding of air-conditioning plastic parts, comprising a processing mechanism 1, a pipe inserting mechanism 2 is provided on the top of the processing mechanism 1, the pipe inserting mechanism 2 comprises a mounting port 21 provided on the top of the processing mechanism 1, a pipe inserting disc 22 is inserted in the mounting port 21, an insertion port 23 is provided on the pipe inserting disc 22, a pipe inserting head 24 is inserted in the insertion port 23, a first limiting block 25 is fixedly connected to the pipe inserting head 24, a first rotating groove 26 is provided in the insertion port 23, a limiting block 26 is provided in the first rotating groove 26 The first limit block 25 rotates along the axial direction of the insertion port 23 after entering the insertion port 23 until the first limit block 25 enters the limit slot 27. An abutment block 28 is provided below the limit slot 27. The abutment block 28 is used to ensure that the first limit block 25 is always in the limit slot 27. A guide rod 281 is provided below the abutment block 28. A guide groove 282 is provided below the insertion port 23. The guide rod 281 is inserted into the guide groove 282. A compression spring 283 is provided on the guide rod 281.

[0024] In the prior art, multiple cannulas are connected to the top of the processing mechanism 1. Repeated insertion and removal processes may result in the cannulas becoming loosely connected to the processing device, potentially causing the cannulas to fall off or the contents of the processing mechanism 1 to leak out. To address this issue, in the present invention, a cannula mechanism 2 is designed on the top of the processing mechanism 1 to ensure the stability and accuracy of continuous feeding. The cannula mechanism 2 has an installation port 21 located at the top of the processing mechanism 1. A cannula disc 22 is inserted into this installation port 21. The cannula disc 22 is provided with an insertion port 23 for inserting a cannula head 24. The cannula head 24 is a key component in the feeding process. A first stopper 25 is fixedly connected to it. This stopper ensures that the cannula head 24 is correctly positioned within the insertion port 23. Once the first stopper 25 enters the insertion port 23, it rotates along the axis of the insertion port 23 until it enters a stopper groove 27. The stopper groove 27 is designed to prevent the first stopper 25 from falling out of the insertion port 23. In order to ensure that the first limit block 25 is always in the limit groove 27, an abutment block 28 is provided below the limit groove 27. The function of this abutment block 28 is to support and fix the first limit block 25 to prevent it from shifting due to vibration or pressure during the feeding process. Below the abutment block 28, a guide rod 281 is provided. This guide rod 281 is inserted into the guide groove 282 below the insertion port 23. In order to increase the stability of the guide rod 281, a compression spring 283 is provided on it. The function of this spring is to provide the necessary pressure to the guide rod 281 during the feeding process to maintain the stability and accuracy of the cannula head 24. The design of the entire cannula mechanism 2, through the coordinated work of the limit block, the limit groove 27, the abutment block 28, the guide rod 281 and the compression spring 283, ensures that the continuous feeding of the air conditioner plastic parts during the injection molding process is both stable and accurate, thereby improving production efficiency and product quality.

[0025] Reference Figure 3-Figure 6 : A locking mechanism 3 is provided between the intubation disk 22 and the mounting port 21, and the locking mechanism 3 includes a locking block 31 provided on the intubation disk 22 and a locking slot 32 provided on the mounting port 21, the locking block 31 is inserted into the locking slot 32, and a through hole 33 is provided on the locking slot 32 and the locking block 31, and a second rotating groove 34 is provided on the top of the processing mechanism 1, and a rotating base 35 is rotatably connected in the second rotating groove 34, and an insert block base 36 is fixedly connected to the rotating base 35, and a locking pin 361 is fixedly connected to the insert block base 36, and when the rotating base 35 rotates along the second rotating groove 34, the insert block base 36 drives the locking pin 361 to be inserted into the through hole 33 on the locking block 31 and the locking slot 32.

[0026] The locking mechanism 3 consists of a locking block 31 on the tube tray 22 and a locking slot 32 on the mounting opening 21. The locking block 31 is inserted into the locking slot 32, and the cooperation between the two ensures the securement of the tube tray 22. To further enhance this securement, both the locking slot 32 and the locking block 31 are provided with through-holes 33. These through-holes 33 allow the locking mechanism 3 to be locked using additional mechanical fasteners. A second rotational groove 34 is provided at the top of the processing mechanism 1. A rotating base 35 is rotatably connected to this groove. An insert base 36 is fixedly connected to the rotating base 35, and a locking pin 361 is fixedly connected to the insert base 36. When the rotating base 35 rotates along the second rotational groove 34, the insert base 36 rotates with it, driving the locking pin 361 to insert into the through-holes 33 in the locking block 31 and the locking slot 32. This design allows the locking mechanism 3 to be locked and unlocked by the rotation of the rotating base 35, providing a simple and effective locking mechanism. During the feeding process, when the tube tray 22 needs to be fixed, the rotating base 35 rotates to insert the locking pin 361 into the through-hole 33, thereby locking the tube tray 22. When the tube tray 22 needs to be removed or adjusted, the rotating base 35 rotates in the opposite direction, and the locking pin 361 is withdrawn from the through-hole 33, unlocking the tube tray 22. This design not only improves the convenience of operation but also ensures the stability of the tube tray 22 during operation, which is crucial for the stability and accuracy of continuous feeding.

[0027] Reference Figure 6 : A gripping handle 362 is provided on the insert block base 36, and the gripping handle 362 is used for the staff to operate the rotating base 35.

[0028] To facilitate the staff's operation of the rotating base 35, a gripping handle 362 is provided on the insert base 36. This gripping handle 362 is used by the staff to grip and rotate the rotating base 35, providing a medium for easy gripping and force application. By gripping the gripping handle 362, the staff can conveniently rotate the rotating base 35 along the second rotating groove 34, thereby driving the insert base 36 and the locking pin 361. When the rotating base 35 rotates, the locking pin 361 will accordingly insert or exit the through hole 33 on the locking block 31 and the locking slot 32, thereby locking or unlocking the tube tray 22. The design of the gripping handle 362 makes the operation process more user-friendly and convenient, reduces the labor intensity of the staff when performing locking and unlocking operations, and improves the efficiency and safety of the operation. Through this design, the staff can easily control the fixed state of the tube tray 22, ensuring the stable operation of the feeding device and the convenience of maintenance work.

[0029] Reference Figures 1-6: A blocking block 4 is inserted in the insertion port 23. When only part of the insertion port 23 needs to insert the cannula head 24, in order to prevent the idle insertion port 23 from causing the contents of the processing mechanism 1 to leak out, the blocking block 4 can be inserted into the insertion port 23. A second limit block 41 is provided in the blocking block 4. When the second limit block 41 enters the insertion port 23, it starts to rotate along the axis of the first rotating groove 26 until the second limit block 41 enters the limit groove 27.

[0030] In order to effectively manage the materials inside the processing mechanism 1 and prevent the materials from leaking out of these idle insertion ports 23 when some of the insertion ports 23 are not in use, a blocking block 4 is designed. The blocking block 4 can be inserted into the unused insertion ports 23 to close these ports and ensure that the materials inside the processing mechanism 1 will not leak out. A second limiting block 41 is provided inside the blocking block 4. The function of this second limiting block 41 is to ensure that the blocking block 4 is fixed in the correct position inside the insertion port 23. When the blocking block 4 is inserted into the insertion port 23, the second limiting block 41 will start to rotate along the axial direction of the insertion port 23 until it enters the limiting groove 27. Through this design, the operator can only insert the cannula head 24 into the insertion port 23 that needs to be fed according to actual production needs, and seal the other unused insertion ports 23 with the blocking block 4. This not only ensures the sealing of the material, but also improves the flexibility and efficiency of the feeding process. At the same time, the coordinated use of the second limit block 41 and the limit groove 27 ensures the stability of the blocking block 4 in the insertion port 23, prevents the blocking block 4 from shifting due to vibration or other external forces, thereby ensuring the sealing of the entire feeding system and the reliability of continuous feeding.

[0031] Reference Figure 5 : A gripping block 42 is provided on the top of the blocking block 4, and the gripping block 42 is provided for the convenience of operation of the staff.

[0032] A gripping block 42 is provided on the top of the blocking block 4. The gripping block 42 is provided to facilitate the staff to conveniently grip and operate the blocking block 4 during operation. The gripping block 42 provides a medium that is easy to grasp, so that the staff can easily insert or remove the blocking block 4 from the insertion port 23 without directly contacting other parts of the blocking block 4, which can improve the convenience and safety of operation. Through the design of the gripping block 42, the staff can more stably and accurately control the insertion and removal of the blocking block 4, ensuring that the blocking block 4 correctly enters the insertion port 23 and is fixed in the limiting groove 27, or is smoothly removed from the insertion port 23. Such a design not only improves work efficiency, but also reduces possible errors during operation, thereby ensuring the stable operation of the entire feeding system and the sealing of the material. The humanized design of the gripping block 42 reflects the consideration of the convenience of operation for the staff, making the entire feeding device easier to use and maintain.

[0033] Reference Figure 3-Figure 6 : A fixing mechanism 5 is provided between the locking mechanism 3 and the processing mechanism 1. The fixing mechanism 5 includes a fixing block 51 provided under the gripping handle 362 and a fixing slot 52 provided on the top of the processing mechanism 1. Pin holes 53 are provided on the fixing block 51 and the fixing slot 52. When the fixing block 51 is inserted into the fixing slot 52, the locking pin 54 is inserted into the pin hole 53 on the fixing block 51 and the fixing pin 54 to fix the locking state of the locking mechanism 3.

[0034] The fixing mechanism 5 consists of a fixing block 51 provided under the gripping handle 362 and a fixing slot 52 provided on the top of the processing mechanism 1. Pin holes 53 are provided on both the fixing block 51 and the fixing slot 52. These pin holes 53 are used to fix the locking state of the locking mechanism 3 through a latch 54. When it is necessary to fix the locking mechanism 3, the operator first inserts the fixing block 51 into the fixing slot 52, and then inserts the latch 54 into the pin holes 53 on the fixing block 51 and the fixing slot 52. In this way, the latch 54 passes through the pin hole 53, tightly connecting the fixing block 51 and the fixing slot 52 together, thereby fixing the locking state of the locking mechanism 3. This fixing method can not only ensure the stability of the locking mechanism 3 during the feeding process, but also prevent the locking mechanism 3 from being accidentally unlocked due to accidental operation or external factors.

[0035] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
