Description

Technical Field

[0001] This application relates to the field of injection molded parts manufacturing, and in particular to an injection molded parts feeding track. Background Technology

[0002] Injection molded parts refer to plastic products manufactured through injection molding. Injection molding involves heating and melting plastic raw materials, then injecting the molten plastic into the mold cavity through the injection device of an injection molding machine. After cooling and solidification, it forms a plastic part with a certain shape and properties.

[0003] During the production of injection molded parts, the molded parts need to be cooled to ensure that their shape is stable and their performance meets the standards. Traditional cooling methods usually involve placing the injection molded parts on a conveyor belt for natural cooling or cooling them with cold air from one direction.

[0004] When using cold air to cool parts, the cold air is often used from a single direction. During the cooling process, the contact surface between the parts and the conveyor belt often does not come into contact with the cold air, resulting in only one side of the parts being effectively cooled. This leads to uneven cooling of the parts and affects their quality. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that during the cooling process, the contact surface between the part and the conveyor belt often does not come into contact with the cold air, resulting in only one side of the part being effectively cooled, leading to uneven cooling of the part and affecting its quality. This application provides an injection molded part unloading track.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A feeding track for injection molded parts includes a support frame, on which two symmetrical support rollers are rotatably connected. Two symmetrical conveyor chains are arranged between the two support rollers. Two symmetrical conveyor gears are drivenly connected to the conveyor chains. The conveyor gears are fixedly connected to the support rollers. A conveyor belt is fixed between the two conveyor chains. A conveyor motor is fixed on the support frame. The output end of the conveyor motor passes through the support frame and is fixedly connected to one of the support rollers. A bidirectional cooling air mechanism is provided on the support frame, and a vibration mechanism is provided on the conveyor belt.

[0008] By adopting the above technical solution, the parts are moved by a ventilated conveyor belt, and then the upper and lower surfaces of the parts are cooled by a bidirectional cooling mechanism, thereby improving the cooling efficiency of the injection molded parts and reducing the possibility of uneven cooling affecting the quality of the parts.

[0009] Furthermore, the bidirectional cooling mechanism includes several air supply pipes fixed to one side of the support frame. One end of each air supply pipe is fixed with an upper air blowing pipe, and the end of each air supply pipe away from the upper air blowing pipe is fixed with a lower air blowing pipe. Both the upper and lower air blowing pipes are connected to the air supply pipes. A blower is fixed on each air supply pipe, and the air supply end of the blower is connected to the air supply pipes. A limit component is provided on the support frame.

[0010] By adopting the above technical solution, the conveyor belt carries the parts through the upper and lower air blowing pipes, thereby enabling simultaneous air blowing and cooling of both the upper and lower surfaces of the parts, improving the cooling efficiency of the parts.

[0011] Furthermore, the limiting assembly includes two limiting rods symmetrically arranged on the support frame, the two limiting rods being located between the conveyor belt and the upper air pipe, and a plurality of limiting rollers being rotatably connected between the two limiting rods.

[0012] By adopting the above technical solution, during the process of the conveyor belt moving the parts, the parts pass under the limiting rollers, thereby reducing the possibility of the parts being blown off the conveyor belt by the downward blowing pipe.

[0013] Furthermore, the support frame is provided with two symmetrical limiting frames, and a lifting threaded rod is rotatably connected to the limiting frame. One end of the lifting threaded rod is provided with a connecting frame, and both ends of the connecting frame are fixedly connected to the two limiting rods.

[0014] By adopting the above technical solution, the lifting threaded rod moves on the limit frame, and the lifting threaded rod drives the connecting frame, thereby making it easy for the connecting frame to drive the two limit rods to adjust the height.

[0015] Furthermore, a connector is provided between the connecting frame and the lifting threaded rod, the connector being rotatably connected to the lifting threaded rod and the connector being rotatably connected to the connecting frame.

[0016] By adopting the above technical solution, the connecting frame and the lifting threaded rod are connected together using a connector, which makes it easy to rotate the lifting threaded rod and to rotate the lifting threaded rods on the two adjusting frames in sequence.

[0017] Furthermore, the shaking mechanism includes several shaking shafts rotatably connected to the support frame. The shaking shafts are located in the conveyor belt, and shaking rods are fixed on the shaking shafts. The shaking rods have a triangular cross-section, and a drive assembly is provided on the support frame.

[0018] By adopting the above technical solution, the shaking shaft drives the shaking rod to rotate, and the edge of the shaking rod pushes the conveyor belt, which makes it easier for the conveyor belt to move parts and cause the parts to vibrate and misalign, reducing the possibility that the parts in contact with the conveyor belt will not be cooled by the air.

[0019] Furthermore, the drive assembly includes a plurality of drive gears rotatably connected to the support frame, the plurality of drive gears corresponding to a plurality of vibrating shafts, one end of the vibrating shaft passing through the support frame and fixedly connected to the drive gears, a drive chain drivingly connecting the plurality of drive gears, a drive motor fixed on the support frame, the output end of the drive motor passing through the support frame and fixedly connected to one of the vibrating shafts.

[0020] By adopting the above technical solution, the vibrating shaft drives the drive gear, the drive gear drives the drive chain, and the drive chain, driven by several limit wheels, causes several drive gears to rotate, which in turn drives the vibrating shaft to rotate, thus making it convenient for several vibrating rods to rotate simultaneously.

[0021] Furthermore, two symmetrical limiting wheels are provided between adjacent drive gears. The limiting wheels are rotatably connected to the support frame and abut against the drive chain.

[0022] By adopting the above technical solution, the limit wheel can limit the drive chain, thereby reducing the possibility of the drive chain separating from the drive gear.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application involves moving freshly injection-molded parts onto a conveyor belt. The conveyor belt moves the parts, positioning them between limiting rollers and the conveyor belt. The limiting rollers and the conveyor belt limit the movement of the parts. Simultaneously, a blower is activated, blowing air into the air supply pipe. The air then enters both the upper and lower air supply pipes, cooling the parts on the conveyor belt. By using the conveyor belt and limiting rollers to limit the movement of the parts, the application achieves simultaneous cooling of both the upper and lower surfaces of the parts, improving cooling efficiency and reducing the possibility of parts being blown by air, thus enhancing the stability of the parts during transport.

[0025] 2. In this application, by allowing the drive chain to rotate under the constraint of several limit wheels, several drive gears rotate. The drive gears drive the vibrating shaft to rotate, and the vibrating shaft drives the vibrating rod. The protruding edges of the vibrating rod alternately push up the conveyor belt, causing the conveyor belt to vibrate. When the conveyor belt vibrates, it drives the parts on the conveyor belt, causing the parts to be misaligned on the conveyor belt. This achieves the purpose of making it easy for the parts to be misaligned on the conveyor belt, reducing the area where the parts are in contact with the conveyor belt from which cooling air cannot be blown.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0034] This application discloses a feeding track for injection molded parts.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A feeding track for injection molded parts includes a support frame 1, on which two symmetrical support rollers 2 are rotatably connected. Two symmetrical conveyor chains 4 are arranged between the two support rollers 2. Two symmetrical conveyor gears 5 are drivenly connected to the conveyor chains 4. The conveyor gears 5 are fixedly connected to the support rollers 2. A conveyor mesh belt 3 is fixed between the two conveyor chains 4. A conveyor motor 8 is fixed on the support frame 1. The output end of the conveyor motor 8 passes through the support frame 1 and is fixedly connected to one of the support rollers 2. A bidirectional cooling air mechanism 6 is provided on the support frame 1. A shaking mechanism 7 is provided on the conveyor mesh belt 3.

[0036] When using this feeding track, the freshly injection-molded parts are first transferred to the conveyor belt 3. The conveyor motor 8 drives one of the support rollers 2 to rotate, causing the conveyor gear 5 on the support roller 2 to drive the conveyor chain 4. The two conveyor chains 4 synchronously drive the conveyor belt 3, which in turn moves several parts. During the movement of the parts, the bidirectional cooling air mechanism 6 blows air to cool the parts on the conveyor belt 3. The bidirectional cooling air mechanism 6 blows air to cool both the top and bottom surfaces of the parts. At the same time, the shaking mechanism 7 causes the conveyor belt 3 to shake. The shaking parts are misaligned on the conveyor belt 3, changing the position of the parts against the conveyor belt 3 and allowing the parts to fully contact the cold air. By using the ventilated conveyor belt 3 to move the parts and then using the bidirectional cooling air mechanism 6 to cool both the top and bottom surfaces of the parts, the cooling efficiency of the injection-molded parts can be improved, reducing the possibility of uneven cooling affecting the quality of the parts.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The bidirectional cooling mechanism 6 includes several air supply pipes 61 fixed to one side of the support frame 1. One end of the air supply pipe 61 is fixed with an upper air blowing pipe 63, and the end of the air supply pipe 61 away from the upper air blowing pipe 63 is fixed with a lower air blowing pipe 64. The upper air blowing pipe 63 and the lower air blowing pipe 64 are both connected to the air supply pipe 61. A blower 62 is fixed on the air supply pipe 61, and the air supply end of the blower 62 is connected to the air supply pipe 61. A limit component 65 is provided on the support frame 1.

[0038] In addition, the limiting assembly 65 includes two limiting rods 651 symmetrically arranged on the support frame 1. The two limiting rods 651 are located between the conveyor belt 3 and the upper air pipe 63, and a number of limiting rollers 652 are rotatably connected between the two limiting rods 651.

[0039] Furthermore, the support frame 1 is provided with two symmetrical limiting frames 653, and a lifting threaded rod 654 is rotatably connected to the limiting frame 653. A connecting frame 655 is provided at one end of the lifting threaded rod 654, and the two ends of the connecting frame 655 are fixedly connected to the two limiting rods 651.

[0040] Furthermore, a connector 656 is provided between the connecting frame 655 and the lifting threaded rod 654, and the connector 656 is rotatably connected to the lifting threaded rod 654 and the connecting frame 655.

[0041] First, determine the height of the part. Then, rotate the lifting threaded rod 654, causing it to drive the connecting frame 655. The connecting frame 655 then drives the two limiting rods 651, positioning the limiting roller 652 between the two limiting rods 651 at a suitable height. Next, move the freshly injection-molded part onto the conveyor belt 3. The conveyor belt 3 moves the part, positioning it between the limiting roller 652 and the conveyor belt 3. The limiting roller 652 and the conveyor belt 3 limit the part's position. Simultaneously, start the blower 62, directing air towards the air supply pipe. Air is supplied through the air supply pipe 61, and then simultaneously enters the upper air blowing pipe 63 and the lower air blowing pipe 64 from the air supply pipe 61. The upper air blowing pipe 63 and the lower air blowing pipe 64 then blow air to cool the parts on the conveyor belt 3. The conveyor belt 3 and the limiting roller 652 limit the parts, reducing the possibility of the parts being blown away. By using the conveyor belt 3 to drive the parts to move, the parts move under the restriction of the conveyor belt 3 and the limiting roller 652. Then, the upper air blowing pipe 63 and the lower air blowing pipe 64 blow air to cool the parts, thereby enabling simultaneous air blowing and cooling of the upper and lower surfaces of the parts, improving the cooling efficiency of the parts.

[0042] Reference Figure 1 , Figure 2 and Figure 5 The shaking mechanism 7 includes several shaking shafts 71 rotatably connected to the support frame 1. The shaking shafts 71 are located in the conveyor belt 3. A shaking rod 72 is fixed on the shaking shaft 71. The shaking rod 72 has a triangular cross section. A drive assembly 73 is provided on the support frame 1.

[0043] In addition, the drive assembly 73 includes a plurality of drive gears 731 rotatably connected to the support frame 1. The plurality of drive gears 731 correspond to a plurality of vibrating shafts 71. One end of the vibrating shaft 71 passes through the support frame 1 and is fixedly connected to the drive gear 731. A drive chain 732 is connected between the plurality of drive gears 731. A drive motor 733 is fixed on the support frame 1. The output end of the drive motor 733 passes through the support frame 1 and is fixedly connected to one of the vibrating shafts 71.

[0044] Furthermore, two symmetrical limiting wheels 734 are provided between adjacent drive gears 731. The limiting wheels 734 are rotatably connected to the support frame 1, and the limiting wheels 734 abut against the drive chain 732.

[0045] When the conveyor belt 3 moves the parts, the drive motor 733 drives one of the vibrating shafts 71 to rotate. The vibrating shaft 71 drives the drive gear 731, which in turn drives the drive chain 732. Under the control of several limit wheels 734, the drive chain 732 causes several drive gears 731 to rotate. The drive gears 731 drive the vibrating shaft 71 to rotate, which in turn drives the vibrating rod 72. The protruding edges of the vibrating rod 72 alternately push up the conveyor belt 3, causing it to vibrate. When the conveyor belt 3 vibrates, it causes the parts on the conveyor belt 3 to become misaligned. By using the vibrating shaft 71 to drive the vibrating rod 72, which in turn causes the conveyor belt 3 to vibrate, it is possible to easily cause the parts to become misaligned on the conveyor belt 3, reducing the possibility that the parts in contact with the conveyor belt 3 will not receive cooling air.

[0046] Working principle: First, determine the height of the part. Then, rotate the lifting threaded rod 654, which drives the connecting frame 655. The connecting frame 655 then drives the two limiting rods 651, positioning the limiting roller 652 between the two limiting rods 651 at a suitable height. Next, move the freshly injection-molded part onto the conveyor belt 3. The conveyor belt 3 moves the part, positioning it between the limiting roller 652 and the conveyor belt 3. The limiting roller 652 and the conveyor belt 3 limit the part's position. Simultaneously, start the blower 62, which blows air into the air supply pipe 61. The air then simultaneously enters the upper air supply pipe 63 and the lower air supply pipe 64. Air blower 64, then upper air blower 63 and lower air blower 64 cool the parts on the conveyor belt 3. At the same time, drive motor 733 drives one of the vibrating shafts 71 to rotate. Vibrating shaft 71 drives drive gear 731. Drive gear 731 drives drive chain 732. Drive chain 732, limited by several limit wheels 734, causes several drive gears 731 to rotate. Drive gear 731 drives vibrating shaft 71 to rotate. Vibrating shaft 71 drives vibrating rod 72. The protruding edge of vibrating rod 72 alternately lifts the conveyor belt 3, causing the conveyor belt 3 to vibrate. The parts move on the conveyor belt 3 while vibrating, and are cooled by the air blower 64 and lower air blower 64.
