Description

Technical Field

[0001] The invention relates to the technical field of straw feeders, and in particular to a speed-adjustable straw feeder. Background Art

[0002] Existing straw feeders may get stuck during the feeding process because the feed port at the feed point cannot be adjusted, and the size of the feeding straws is much larger than the size of the feed port. Although straws have a certain toughness and those slightly larger than the feed port can be pushed in, those much larger than the feed port cannot be pushed in because the thrust provided by the pushing belt is limited. However, since many current feeders may feed straws of different sizes at the same time, how to make the feed port adjustable to accommodate the simultaneous feeding of straws of different sizes is a technical problem to be solved. Summary of the invention

[0003] The purpose of the present invention is to provide a speed-adjustable straw feeder, which ensures that only one straw passes through each time by precisely controlling the distance between the baffle and the belt, and can monitor abnormal conditions during the feeding process in real time through a pressure sensor, thereby realizing automated and intelligent straw distribution and transportation. The device can effectively avoid problems such as straw accumulation, blockage, and uneven feeding, improve the continuity and stability of the production line, and reduce manual intervention and production costs. In addition, by precisely controlling the distribution interval and conveying speed of the straws, the present invention can also flexibly adapt to the production of straws of different specifications, improve the adaptability and efficiency of the production line, and solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a speed-adjustable straw loader, comprising a support frame, a loading hopper is provided at the upper end of the support frame, a lifting device is provided on one side of the loading hopper, a belt conveyor is provided inside the loading hopper, a drop port is provided on one side of the loading hopper, a baffle is provided at the upper end of the belt conveyor, a tooth groove is provided on one side of the baffle, a gear is meshed with the tooth groove, a rotating shaft is fixed inside the gear, a first motor is installed at the rear end of the loading hopper, and the output end of the first motor is transmission-connected to the rotating shaft.

[0005] Preferably, the front end and the rear end of the baffle are slidably provided with slide grooves, and the slide grooves are fixedly connected to the upper hopper.

[0006] Preferably, a guide plate is provided above one side of the belt conveyor, and the guide plate is fixedly connected to the upper hopper.

[0007] Preferably, the lifting device comprises a baffle frame, a fixing plate is fixedly provided at the lower end of the baffle frame, and the fixing plate is fixed to the supporting frame.

[0008] Preferably, a discharge platform is provided on one side of the retaining frame, and the discharge platform is fixedly connected to the retaining frame.

[0009] Preferably, a transmission belt is arranged inside the retaining frame, a driving roller is arranged inside the transmission belt, synchronous rollers are arranged on both sides of the driving roller, and the synchronous rollers are connected to the retaining frame through bearings.

[0010] Preferably, a second motor is installed at the rear end of the retaining frame, and the output end of the second motor is transmission-connected to the driving roller.

[0011] Preferably, a receiving plate is provided on the outer wall of the transmission belt, a pressure sensor is provided inside the receiving plate, a display screen controller is provided at the front end of the retaining frame, and the display screen controller is electrically connected to the pressure sensor.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention proposes a speed-adjustable straw loader, which drives the rotating shaft through the first motor, and then drives the gear to engage with the tooth groove, so as to adjust the distance between the baffle and the belt. The baffle ensures that only one straw passes through at a time and falls on the transmission receiving plate through the drop port, and can accurately control that only one straw passes through at a time. This avoids the passage of multiple straws at the same time, avoids accumulation, congestion or errors during the transportation process, and ensures that each straw can accurately enter the subsequent production links. The automated adjustment method enables the position of the baffle to be accurately controlled according to production needs, reducing the need for manual intervention. The equipment can automatically complete the distribution and transportation of straws without manual adjustment, greatly improving the efficiency and automation level of the production line. At the same time, since only one straw is delivered at a time, straw blockage and shutdown are avoided, and production continuity and efficiency are improved. The precise adjustment of the baffle and the single-piece delivery method of the straw can ensure that each straw is distributed according to the predetermined interval and position, avoiding the uneven phenomenon caused by the simultaneous passage of multiple straws. Under the action of the belt conveyor, the straw falls accurately on each receiving plate through the drop port, ensuring the stability and smoothness of the straw during the transmission process. Through this precise drop method, the straws will not be offset or uneven, ensuring that they can smoothly enter the next process and avoiding production line interruptions caused by unstable materials. In addition, by adjusting the spacing between the baffle and the belt, it can flexibly adapt to the production of straws of different specifications or types. Regardless of whether the straws are of different lengths and diameters, the spacing can be automatically adjusted to ensure the smoothness and stability of the production process, meet the needs of different product specifications, and improve the adaptability of the production line.

[0013] 2. The present invention proposes a speed-adjustable straw feeder, which monitors the pressure changes on the receiving plate in real time by setting a pressure sensor inside the receiving plate, and feeds back the feeding situation through the display controller in real time, so as to promptly discover problems such as uneven feeding or blockage of the conveyor belt. This real-time monitoring allows production personnel to make adjustments quickly, thereby improving production efficiency and avoiding shutdowns and waste caused by feeding problems. By monitoring the pressure distribution on the receiving plate through a pressure sensor, it is possible to accurately detect whether there are foreign objects or abnormal conditions, such as material blockage or uneven flow, during the production process. This provides an important guarantee for the quality control of the straws, ensuring that the production of each straw meets the quality requirements. The pressure sensor can promptly detect abnormal changes in the operation of the equipment, such as too fast or uneven feeding, and help to adjust the production rhythm in time. The use of pressure sensors can minimize manual intervention in the feeding process, automatically monitor and adjust the feeding situation, improve the automation level of the production line, reduce errors caused by human operation, and improve the stability and consistency of production.

[0014] 3. The invention proposes a speed-adjustable straw loader. Through the precise control of the belt conveyor, the straws can stably and accurately fall on the belt of the elevator, avoiding the misplacement or accumulation of materials, thereby ensuring the smooth operation of the production line. The belt drive speed is adjustable, and the conveying and lifting speeds can be flexibly adjusted according to different production needs, avoiding too fast or too slow situations. Due to the precise placement of the straws during the conveying process, collision, falling or damage of the materials is avoided, which helps to reduce the losses caused by improper transmission in the production process and improves product quality and production cost control.
