Description

Technical Field

[0001] This utility model relates to the field of foam production technology, specifically to a feeding device for foam production equipment. Background Technology

[0002] Foamed plastics are plastic products with synthetic resin as the matrix and countless tiny pores inside. They are widely used in daily life and industrial fields. Almost all kinds of plastics can be made into foamed plastics. Foaming molding has become an important field in plastic processing. In the foam production and processing process, it is necessary to use a feeding device to mix and feed the foam material.

[0003] A pressurized feeding device for foam production equipment disclosed in Chinese Patent Publication No. CN212331628U uses a pressure sensor installed in the feeding hopper to detect the weight of the raw materials entering the hopper in real time. When the weight reaches a certain value, the sensor transmits the detected signal to the controller, which then controls the second valve to close, thereby controlling the weight of the raw materials fed into the foam production machine. However, the feeding device has low overall flexibility, the foam material cannot be fully mixed and stirred, and the dust particles mixed in the foam material are not easy to clean quickly, thus affecting the subsequent use effect of the feeding device. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for foam production equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for foam production equipment, comprising a feeding hopper, a stirring blade rotatably connected to the middle position of the top of the feeding hopper, a ventilation mechanism provided at the middle position of one side of the feeding hopper, a collection hopper installed on the side of the feeding hopper away from the ventilation mechanism, a filter plate fixedly connected to one side of the collection hopper, a guide seat fixedly connected to the middle position of one side of the feeding hopper, an electric valve installed on one side of the guide seat, a lifting mechanism provided inside the guide seat, a support plate rotatably connected to the bottom of the feeding hopper, a weighing instrument installed at the middle position of the top of the support plate, a side plate fixedly connected to one side of the top of the support plate, a reset mechanism provided inside the side plate, and a push plate provided on one side of the reset mechanism.

[0006] Preferably, a viewing window is installed on one side of the outside of the feeding hopper, a feed inlet is installed at the middle position of the top of the feeding hopper, and a discharge valve is installed at the bottom of one side of the feeding hopper.

[0007] Preferably, the ventilation mechanism includes an air inlet chamber fixedly connected to the middle of one side of the feeding hopper, and high-speed fans are evenly installed at equal intervals inside the air inlet chamber.

[0008] Preferably, the lifting mechanism includes a motor installed inside one side of the guide seat, a take-up shaft installed at the output shaft end of the motor, and pull ropes fixedly connected to the bottom end of the take-up shaft and fixedly connected to the support plate on both sides outside the take-up shaft.

[0009] Preferably, the reset mechanism includes a slide rod fixedly connected to the middle position inside the side plate, a slider fixedly connected to one side of the slide rod, and a spring fixedly connected to one side of the slider.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The feeding device of this foam production equipment has a stirring blade installed at the middle position of the top of the feeding hopper. When the foam material is poured into the inside of the stirring blade, the high-speed fan in the ventilation mechanism can accelerate the input of external air into the feeding hopper. At this time, the external accelerated air can drive the stirring blade to rotate and make the stirring blade quickly stir and mix the foam material inside. At the same time, the accelerated air can blow away small particulate impurities in the foam material in the feeding hopper and make the impurities pass through the filter plate into the collection hopper for centralized treatment, thereby improving the overall functionality and use effect of the feeding device.

[0012] 2. The feeding device of this foam production equipment has a weighing instrument installed at the top of the pallet. When the mixed foam material falls from the electric valve into the top of the weighing instrument, the weighing instrument can weigh the foam material. When the foam material reaches a suitable weight, the lifting mechanism releases the rope, which can tilt one side of the pallet. At this time, the discharge valve can quickly feed the foam material. At the same time, during the tilting process of the pallet, due to the effect of gravity, the push plate can push the foam material at the top of the pallet to move quickly, thereby accelerating the discharge of the foam material.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides two technical solutions:

[0020] Example 1: A feeding device for a foam production equipment includes a feeding bin 1. A stirring blade 2 is rotatably connected to the middle position of the top of the feeding bin 1. A ventilation mechanism 3 is provided at the middle position of one side of the feeding bin 1. A collection bin 4 is installed on the side of the feeding bin 1 away from the ventilation mechanism 3. A filter plate 401 is fixedly connected to one side of the collection bin 4. A guide seat 104 is fixedly connected to the middle position of one side of the feeding bin 1. An electric valve 105 is installed on one side of the guide seat 104. By opening the electric valve 105, the mixed foam material can fall onto the weighing instrument 601 at the top of the tray 6.

[0021] The guide seat 104 is equipped with a lifting mechanism 5. The bottom of the feed hopper 1 is rotatably connected to a support plate 6. A weighing instrument 601 is installed at the middle position of the top of the support plate 6. A side plate 7 is fixedly connected to one side of the top of the support plate 6. A reset mechanism 8 is installed inside the side plate 7. A push plate 9 is installed on one side of the reset mechanism 8.

[0022] A viewing window 101 is installed on one side of the outside of the feeding hopper 1. An inlet 102 is installed at the middle of the top of the feeding hopper 1. A discharge valve 103 is installed at the bottom of one side of the feeding hopper 1. The viewing window 101 can observe the feeding of foam material in the feeding hopper 1. At the same time, the inlet 102 can be used to feed foam material, and the discharge valve 103 can be opened to feed foam material.

[0023] The ventilation mechanism 3 includes an air inlet chamber 301 fixedly connected to the middle of one side of the feeding chamber 1. High-speed fans 302 are evenly installed at equal intervals inside the air inlet chamber 301. When the high-speed fans 302 are started, they can accelerate the input of external air into the feeding chamber 1 and drive the stirring blades 2 to rotate.

[0024] Example 2 differs from Example 1 mainly in that:

[0025] A feeding device for a foam production equipment includes a lifting mechanism 5 comprising a motor 501 installed on one side inside a guide seat 104. A take-up shaft 502 is installed on the output shaft end of the motor 501. Pull ropes 503, whose bottom ends are fixedly connected to a support plate 6, are fixedly connected to both sides of the take-up shaft 502. When the motor 501 is started, it can drive the take-up shaft 502 to rotate. At this time, the take-up shaft 502 can pull the pull ropes 503 on both sides of the outside to retract and extend, and the pull ropes 503 can drive one end of the support plate 6 to move up and down.

[0026] The reset mechanism 8 includes a slide rod 801 fixedly connected to the middle position inside the side plate 7. A slider 802 is slidably connected to the outside of the slide rod 801 and fixedly connected to the push plate 9 on one side. A spring 803 is fixedly connected to one side of the slider 802. The push plate 9 can slide on the support plate 6 under the influence of gravity and push the foam material at the top of the support plate 6 to move. At the same time, the push plate 9 can squeeze the spring 803 through the slider 802. When the support plate 6 is kept in a horizontal state, the push plate 9 can be quickly reset by pushing it through the slider 802 due to the reaction force of the squeezed spring 803. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0027] In this embodiment of the application, when in use: by opening the feed inlet 102, the foam material to be mixed can be poured into the top of the feeding hopper 1. At this time, the high-speed fan 302 in the air inlet 301 is started, which can accelerate the external air into the feeding hopper 1 and make the stirring blade 2 rotate. At this time, the stirring blade 2 can quickly stir the foam material at the top of the feeding hopper 1. At the same time, small particulate impurities in the foam material can be blown into the collection hopper 4 through the filter plate 401. After the mixing is completed, the electric valve 105 is opened, which allows the foam material to fall into the top of the tray 6 and be weighed by the weighing instrument 601. When the foam material reaches a suitable weight, the motor 501 in the guide seat 104 is started, which can drive the pull rope 503 to release the line through the winding shaft 502. At this time, the left side of the tray 6 will tilt due to gravity, and the discharge valve 103 is opened to enable the rapid feeding of foam material.
