Technical Field

[0001] This utility model belongs to the technical field of feeding devices, specifically relating to a feeding device for corrugated pipe production. Background Technology

[0002] Steel strip corrugated pipe is a corrugated pipe made by extruding plastic onto the outer wall of a steel strip using an extruder. After years of development and improvement, its production process and application technology are very mature. Due to its excellent performance and relatively economical cost, the promotion and application of corrugated pipe is on the rise. Corrugated pipe is extruded from molten plastic granules, and production requires feeding material into the hopper.

[0003] The commonly used automatic feeding device feeds material at timed intervals. This means that the amount of material consumed is calculated based on the extruder's working time, and then the material is fed at timed intervals according to the hopper's capacity. This feeding method is affected by the extruder's working speed, and different feeding times need to be adjusted for different extruders, which is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated pipe production feeding device that can overcome the influence of extruder efficiency, has higher practicality, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated pipe production feeding device, comprising a feeding barrel and a storage bin, wherein a screw conveyor is provided between the feeding barrel and the storage bin, and an excess material sensing structure is provided at the bottom of the feeding barrel, the excess material sensing structure comprising a cylinder slidably connected inside the feeding barrel, a second conical hopper fixedly connected to the bottom end of the cylinder, a second conical hopper provided on the outer wall of the cylinder, a ring plate fixedly connected to the outer wall of the cylinder, and a spring for supporting the ring plate fixedly connected to the bottom end of the ring plate.

[0006] Furthermore, the feeding hopper includes a cylindrical body, the cylinder is slidably connected inside the cylindrical body, a first conical hopper is fixedly connected to the bottom end of the cylindrical body, a discharge pipe is provided at the bottom end of the first conical hopper, the discharge pipe passes through the bottom end of the first conical hopper, a diaphragm cylinder is provided on the side wall of the cylindrical body, and the ring plate is slidably connected inside the diaphragm cylinder.

[0007] Furthermore, the bottom end of the storage hopper is fixedly connected to the bottom of the side wall of the screw conveyor, and the top end of the screw conveyor penetrates the side wall of the cylinder.

[0008] Furthermore, a sleeve is fixedly connected to the bottom end of the second conical hopper, and the sleeve is movably fitted onto the top of the discharge pipe.

[0009] Furthermore, a support plate for supporting the ring plate is fixedly connected to the middle of the abductor cylinder. The surface of the support plate is provided with equidistantly distributed through holes. There are several springs, and the springs pass through the several through holes respectively. The two ends of the springs are fixedly connected to the bottom end of the inner wall of the abductor cylinder and the bottom end of the ring plate respectively.

[0010] Furthermore, a proximity switch is fixedly installed at the top of the diaphragm cylinder, and a controller is fixedly connected to the outer wall of the cylinder.

[0011] Furthermore, the proximity switch is electrically connected to the controller, and the controller is electrically connected to the screw conveyor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When this device is in use, as the material inside the feeding barrel is consumed by the extruder, the cylinder and ring plate move upward under the elastic force of the spring.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figure 1-3As shown, a corrugated pipe production feeding device includes a feeding barrel 1 and a storage bin 2. A screw conveyor 3 is arranged between the feeding barrel 1 and the storage bin 2. An excess material sensing structure 4 is provided at the bottom of the feeding barrel 1. The excess material sensing structure 4 includes a cylinder 41 slidably connected inside the feeding barrel 1. A second conical hopper 42 is fixedly connected to the bottom end of the cylinder 41. The outer wall of the cylinder 41 is provided with the second conical hopper 42. An annular plate 44 is fixedly connected to the outer wall of the cylinder 41. A spring 46 for supporting the annular plate 44 is fixedly connected to the bottom end of the annular plate 44. The bottom end of the storage bin 2 is fixedly connected to the bottom of the side wall of the screw conveyor 3. The top end of the screw conveyor 3 penetrates the side wall of the cylinder 11.

[0017] According to the above structure, during use, the screw conveyor 3 transports the plastic granules inside the storage bin 2 to the inside of the feeding barrel 1. The plastic granules transported to the inside of the feeding barrel 1 exert downward pressure on the cylinder 41 and the second conical hopper 42. The cylinder 41 and the second conical hopper 42 move downward and compress the spring 46. As the material inside the feeding barrel 1 is consumed by the extruder, under the elastic force of the spring 46, the cylinder 41 and the ring plate 44 move upward. When the cylinder 41 and the ring plate 44 rise to the corresponding height, the material inside the feeding barrel 1 is completely consumed. At this time, the screw conveyor 3 automatically transports material into the inside of the feeding barrel 1, thereby realizing the automatic addition of material.

[0018] like Figure 3 As shown, the feeding hopper 1 includes a cylindrical body 11, a cylindrical cylinder 41 slidably connected inside the cylindrical body 11, a first conical hopper 12 fixedly connected to the bottom end of the cylindrical body 11, a discharge pipe 13 provided at the bottom end of the first conical hopper 12, the discharge pipe 13 penetrating the bottom end of the first conical hopper 12, a diaphragm cylinder 14 provided on the side wall of the cylindrical body 11, and a ring plate 44 slidably connected inside the diaphragm cylinder 14.

[0019] According to the above structure, when conveying materials, the screw conveyor 3 conveys the materials inside the storage bin 2 to the inside of the cylinder 11.

[0020] like Figure 3 As shown, the bottom end of the second conical hopper 42 is fixedly connected to a sleeve 43, which is movably sleeved on the top of the discharge pipe 13. The middle part of the abductor cylinder 14 is fixedly connected to a support plate 45 for supporting the ring plate 44. The surface of the support plate 45 is provided with through holes distributed at equal intervals. There are several springs 46, which pass through several through holes respectively. The two ends of the springs 46 are fixedly connected to the bottom end of the inner wall of the abductor cylinder 14 and the bottom end of the ring plate 44 respectively.

[0021] According to the above structure, when the material is conveyed to the cylinder 11, the material presses down on the cylinder 41 and the second conical hopper 42. When the bottom end of the ring plate 44 contacts the top end of the support plate 45, the support plate 45 supports the ring plate 44 to prevent the spring 46 from being excessively compressed.

[0022] like Figure 2 and 3 As shown, a proximity switch 6 is fixedly installed at the top of the cylinder 14, and a controller 5 is fixedly connected to the outer wall of the cylinder 11. The proximity switch 6 is electrically connected to the controller 5, and the controller 5 is electrically connected to the screw conveyor 3.

[0023] According to the above structure, as the material is consumed, the spring 46 supports the ring plate 44 to move upward. When the distance between the ring plate 44 and the proximity switch 6 is shortened to 1-2 cm, the proximity switch 6 sends a signal to the controller 5. The controller 5 controls the screw conveyor 3 to start for a certain period of time to inject a corresponding number of plastic granules into the inside of the cylinder 11.

[0024] The working principle of this utility model is as follows: During use, the screw conveyor 3 transports the plastic granules inside the storage bin 2 to the inside of the feeding barrel 1. The plastic granules transported to the inside of the feeding barrel 1 exert downward pressure on the cylinder 41 and the second conical hopper 42. The cylinder 41 and the second conical hopper 42 move downward and compress the spring 46. When the bottom end of the ring plate 44 contacts the top end of the support plate 45, the support plate 45 supports the ring plate 44 to prevent the spring 46 from being over-compressed. As the material is consumed, the spring 46 supports the ring plate 44 to move upward. When the distance between the ring plate 44 and the proximity switch 6 is shortened to 1-2 cm, the proximity switch 6 sends a signal to the controller 5. The controller 5 controls the screw conveyor 3 to start for a certain period of time to inject a corresponding number of plastic granules into the inside of the cylinder 11.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
