Description

Technical Field

[0001] This utility model relates to the field of foam processing technology, and in particular to an automatic feeding device for foam processing. Background Technology

[0002] Foam processing is a plastic processing technology that mainly produces foamed plastic products with properties such as lightweight, pressure resistance, and heat insulation.

[0003] The application of feeding devices to improve the processing efficiency of foam processing is becoming increasingly widespread. Automatic feeding devices for foam processing have significant advantages in improving production efficiency and reducing manual operation. However, the drive structure of existing automatic feeding devices is relatively complex, and the maintenance cost is high. At the same time, the material is prone to sticking during the feeding process. To solve the above problems, we propose an automatic feeding device for foam processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding device for foam processing.

[0005] By adopting the above technical solution

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic feeding device for foam processing includes a foam processing machine. The machine has an inlet on its upper side, and a feeding chute is installed on the inlet. A support is provided on the side of the machine, and a turntable is rotatably mounted on the support. The turntable has a circular groove, and several conveying boxes are installed inside the groove. A large gear is mounted on the side of the turntable, and a motor is located below the large gear. A small gear is mounted on the output end of the motor, and the large gear meshes with the small gear. A folding rod is fixedly mounted on the side of the support, and a [missing information - likely a device or equipment] is provided on the folding rod. The device includes a cleaning assembly and an intermittent start assembly. The cleaning assembly includes an air pump, which is fixedly mounted on a folding rod. An air extraction pipe and a flared nozzle are connected to the air pump. The intermittent start assembly includes a bearing seat. A vertical support is fixedly mounted on the upper side of the folding rod. The bearing seat is fixedly mounted on the vertical support. A rotating shaft is rotatably mounted on the bearing seat. A torsion spring is provided on the outer side of the rotating shaft. A rotating rod is fixedly mounted on the rotating shaft. An upper contact electrode is provided at the bottom of the rotating rod. A lower contact electrode is installed on the side of the vertical support. A lever is installed on the side of the turntable.

[0008] Preferably, a side support plate is fixedly installed on the side of the foam processing equipment, and the bracket is fixedly installed on the upper side of the side support plate.

[0009] Preferably, a reinforcing connecting plate is provided at the bottom of the side support plate.

[0010] By adopting the above technical solution, a reinforcing connecting plate is added to the bottom of the side support plate, which strengthens the load-bearing capacity of the side support plate for the upper structure and improves the structural stability.

[0011] Preferably, the feed trough is arranged at an angle.

[0012] Preferably, a base is fixedly installed on the side of the bracket, and the motor is fixedly installed on the upper side of the base.

[0013] By adopting the above technical solution, the base provides a support structure for the motor.

[0014] Preferably, a feeding pipe is provided on the side of the turntable.

[0015] Preferably, the conveying box is provided in eight groups at equal intervals along the circumference of the circular groove.

[0016] Preferably, the position of the lever corresponds one-to-one with the position of the delivery box.

[0017] By adopting the above technical solution, the conveyor boxes and levers are set up in a one-to-one correspondence and distributed at equal intervals along the circumference, so that the turntable can synchronously drive the conveyor boxes and levers to rotate when it rotates.

[0018] Preferably, the flared nozzle is tilted upwards.

[0019] Preferably, the upper contact electrode and the lower contact electrode are respectively connected to the power supply line of the air pump, and a limit frame is provided on the upper side of the rotating rod, and the limit frame is fixedly installed on the upper side of the vertical support.

[0020] By adopting the above technical solution, the upper contact electrode and the lower contact electrode are respectively connected to the power supply line of the air pump. When the upper contact electrode and the lower contact electrode touch, the air pump is turned on. After being turned on, the air pump draws air and blows it obliquely upward through the flared nozzle, which blows away the material stuck inside the conveying box groove, so as to avoid the material from sticking and being unable to slide from the conveying box into the feeding trough.

[0021] Compared with related technologies, the automatic feeding device for foam processing proposed in this utility model has the following advantages:

[0022] In this utility model, an automatic feeding device for foam processing is described. Through a cleaning assembly, when the air pump is powered on, it draws in air through a suction pipe and blows high-pressure gas upwards through a flared nozzle. When the high-pressure gas reaches the inside of the conveying box, the material adhering to the inside of the conveying box loosens under the air pressure. Then, after the air pump stops working, the material automatically slides into the lower feeding trough under gravity. Simultaneously, the air pump's operating status is controlled by an intermittent start assembly, connecting the upper and lower contact electrodes to the air pump's power supply circuit. When the conveying... When the box rotates to the upper part of the flared nozzle, the side lever presses down on the rotating rod, connecting the upper and lower contact poles and energizing the air pump. When the lever rotates past the working range of the rotating rod, the air pump circuit is disconnected. This design allows the air pump to automatically start spraying air onto the box when it approaches the flared nozzle, and to automatically stop when it passes the nozzle, preventing continuous blowing that could cause material to fly around. The intermittent blowing also prevents material from sticking to the inside of the box, improving the conveying efficiency of the device. Furthermore, the conveying components in this device have a simple structural design, making maintenance relatively convenient. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 An automatic feeding device for foam processing includes a foam processing equipment 1. The foam processing equipment 1 has a feed inlet 2 on its upper side. It should be noted that the foam processing equipment 1 can be a foam hot melt machine, a device used to process foam plastics. Its main purpose is to heat the foam plastic to its melting point to melt it, and then reshape or recycle it. This type of machine has important applications in waste recycling and the reprocessing of plastic products, which will not be elaborated upon here. A feed trough 3 is also installed on the feed inlet 2. A bracket 5 is provided on the side of the foam processing equipment 1, and a side support plate 4 is fixedly installed on the side of the foam processing equipment 1. The bracket 5 is fixedly installed on the upper side of the side support plate 4, and the bracket 5 rotates on the side support plate 4. A turntable 6 is installed, and a feeding pipe 9 is set on the side of the turntable 6. It should be noted that the feeding pipe 9 is a conventional technical means used for conveying materials in the existing workshop. It belongs to the material pumping system and will not be described in detail here. A circular groove 7 is opened on the turntable 6, and several conveying boxes 8 are installed inside the circular groove 7. A large gear 11 is installed on the side of the turntable 6, and a motor 13 is set below the large gear 11. A base 12 is fixedly installed on the side of the bracket 5, and the motor 13 is fixedly installed on the upper side of the base 12. A small gear 14 is installed on the output end of the motor 13. The large gear 11 and the small gear 14 mesh. A folding rod 15 is fixedly installed on the side of the bracket 5, and a cleaning component and an intermittent start component are set on the folding rod 15.

[0030] With the above structure, when the starting motor 13 rotates, the output end of the motor 13 drives the small gear 14 to rotate. Under the action of meshing transmission, the large gear 11 also rotates, its speed decreases and its torque increases. The large gear 11 drives the turntable 6 to rotate, and the conveying box 8 in the turntable 6 rotates synchronously. When the material is added to the side of the turntable 6 by the feeding pipe 9, the conveying box 8 rotates upward to drive the material to the other side of the turntable 6. As the conveying box 8 rotates, its opening direction gradually faces downward. Under the action of gravity, the material slides from the conveying box 8 along the circular groove 7 to the feeding groove 3. Subsequently, the feeding groove 3 sends the material into the foam processing equipment 1.

[0031] In this embodiment, the cleaning assembly includes an air pump 16, which is fixedly mounted on the folding rod 15. An air extraction pipe 17 and a flared nozzle 18 are connected and installed on the air pump 16, with the flared nozzle 18 tilted upwards.

[0032] With the above structure, the flared nozzle 18 is set at an upward angle. When the air pump 16 is started, the flared nozzle 18 generates an upward blowing action, which can loosen the material stuck in the conveying box 8. Then, when the air pump 16 stops working, the loosened material automatically falls into the feed trough 3 under the action of gravity.

[0033] In this embodiment, the intermittent start assembly includes a bearing seat 20, a vertical support 19 fixedly mounted on the upper side of the lever 15, the bearing seat 20 fixedly mounted on the vertical support 19, a rotating shaft 21 rotatably mounted on the bearing seat 20, a torsion spring 22 provided on the outer side of the rotating shaft 21, a rotating rod 23 fixedly mounted on the rotating shaft 21, an upper contact electrode 24 provided at the bottom of the rotating rod 23, a lower contact electrode 25 installed on the side of the vertical support 19, and a lever 10 installed on the side of the turntable 6.

[0034] With the above structure, when the delivery box 8 rotates to the upper side of the flared nozzle 18, the lever 10 on the side of the turntable 6 presses down the rotating rod 23 to connect the upper contact electrode 24 and the lower contact electrode 25, thus making the power circuit of the air pump 16 conductive. When the lever 10 rotates through the range of action with the rotating rod 23, the circuit of the air pump 16 is disconnected.

[0035] In this embodiment, a reinforcing connecting plate is provided at the bottom of the side support plate 4.

[0036] The above structure strengthens the connection plate, thereby increasing the load-bearing capacity of the side support plate 4.

[0037] In this embodiment, the feed trough 3 is arranged at an angle.

[0038] In this embodiment, eight sets of conveyor boxes 8 are equidistantly arranged along the circumference of the circular groove 7, and the positions of the levers 10 correspond one-to-one with those of the conveyor boxes 8.

[0039] With the above structure, the positions of the conveyor box 8 and the lever 10 are corresponding. When each conveyor box 8 on the turntable 6 rotates to an angle above the flared nozzle 18, it will generate a blowing effect under the action of the lever 10, thereby cleaning each conveyor box 8.

[0040] In this embodiment, the upper contact electrode 24 and the lower contact electrode 25 are respectively connected to the power supply line of the air pump 16, and a limit frame 26 is provided on the upper side of the rotating rod 23. The limit frame 26 is fixedly installed on the upper side of the vertical support 19.

[0041] Through the above structure, the setting of the limiting frame 26 prevents the rotating rod 23 from tilting excessively due to the torque of the torsion spring 22, thereby preventing the side of the rotating rod 23 from failing to contact the lever 10.

[0042] In this invention, when the motor 13 is started and rotated, the output of the motor 13 drives the small gear 14 to rotate, which in turn drives the large gear 11 to rotate the turntable 6. Consequently, the conveying box 8 located within the turntable 6 rotates synchronously. When material is added to the side of the turntable 6 via the feeding pipe 9, the conveying box 8 rotates upwards, carrying the material to the other side of the turntable 6. As the conveying box 8 rotates, its opening gradually faces downwards. When the conveying box 8 rotates to the upper side of the flared nozzle 18... At this time, the lever 10 on the side of the turntable 6 presses down the rotating rod 23, connecting the upper contact electrode 24 and the lower contact electrode 25. The air pump 16 draws in air through the suction pipe 17 and blows high-pressure gas into the inside of the conveying box 8 through the flared nozzle 18, breaking the adhesion of the material adhering to the inside of the conveying box 8. When the lever 10 rotates through the area of ​​action with the rotating rod 23, the circuit of the air pump 16 is disconnected, the flared nozzle 18 stops blowing air, and the loosened residual material slides down into the feed trough 3 under the action of gravity. The above is the working process and principle of this utility model. The design of the cleaning component and the intermittent start component in this utility model automatically turns on the air pump 16 to spray air into the conveying box 8 when the conveying box 8 approaches the flared nozzle 18, and automatically stops the air pump 16 when it rotates past the nozzle, avoiding continuous blowing that causes the material to fly around. At the same time, the intermittent blowing effect also prevents the material from adhering to the inside of the conveying box 8, improving the conveying efficiency of this device.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
