Description

Technical Field

[0001] This utility model relates to the field of bamboo chopsticks production technology, specifically to a screening machine for bamboo chopsticks production. Background Technology

[0002] In the industrial production of bamboo chopsticks, the final fine sorting process has long been a technical bottleneck.

[0003] Traditional bamboo chopstick sorting equipment is mostly based on macroscopic dimensional parameters such as length and diameter for sorting. However, the directional sorting of the front and back of the chopsticks still relies on manual visual inspection, resulting in high labor costs and low efficiency. Utility Model Content

[0004] (I) Problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a screening machine for bamboo chopstick production that is easy to operate and use and improves screening efficiency.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a screening machine for bamboo chopstick production, including a machine housing, a screening chamber inside the machine housing, and a chopstick inlet between the screening chamber and the top of the machine housing;

[0008] The screening chamber is equipped with a feeding wheel that rotates inside. The feeding wheel has several troughs that can accommodate bamboo chopsticks that are recessed inward along its circumference. The gap between the inner wall of the screening chamber and the feeding wheel is smaller than the diameter of the bamboo chopsticks.

[0009] An inclined discharge trough is provided at the lower end of the screening chamber inside the machine casing, and the bottom of the discharge trough is connected to a material distribution slope with an inverted V-shaped cross section. Discharge ports are provided between the two walls of the machine casing and the two ends of the material distribution slope.

[0010] As an improvement, the outer wall of the housing is also provided with a material-collecting frame near the discharge port, and the outer wall of the housing is also provided with a magnetic suction plate near the material-collecting frame. The material-collecting frame and the housing are magnetically attracted to each other through the magnetic suction plate.

[0011] As an improvement, a material-blocking plate and a material-relieving plate are respectively connected to the two sides of the inlet near the screening chamber;

[0012] The deceleration plate is positioned close to the rotation direction of the feeding wheel, and a buffer spring is provided between the deceleration plate and the inner wall of the screening chamber.

[0013] As an improvement, a drive motor is also connected to the outer wall of the housing, and a synchronous belt is sleeved between the shaft end of the feeding wheel, which passes through the outer wall of the housing and the rotating end of the drive motor.

[0014] As an improvement, an opening is provided on one side of the housing at the end of the material distribution slope, and a baffle plate is hinged to the opening.

[0015] (III) Beneficial Effects

[0016] The advantages of this utility model compared with the prior art are as follows: In this application, the chopsticks are fed at a constant speed by means of a feeding wheel and a slowing trough. At the same time, the chopsticks are distinguished by weight by means of a discharge trough and a separating slope, taking advantage of the difference in weight between the large and small ends of the chopsticks. The discharge port set with the separating slope facilitates the slow processing of the chopsticks and prevents them from flipping over during discharge, thus ensuring the screening effect.

[0026] Please refer to the appendix carefully. Figure 1-3 A screening machine for bamboo chopsticks production includes a housing 1, a screening chamber 2 inside the housing 1, and a chopstick inlet 3 between the screening chamber 2 and the top of the housing 1.

[0027] A feeding wheel 4 is rotatably installed inside the screening chamber 2. Several slowing grooves 5 that can accommodate bamboo chopsticks are recessed inward along its circumference on the feeding wheel 4. The gap between the inner wall of the screening chamber 2 and the feeding wheel 4 is smaller than the diameter of the bamboo chopsticks.

[0028] The machine casing 1 has an inclined discharge trough 6 located at the lower end of the screening chamber 2, which is connected to the discharge trough 6. The bottom end of the discharge trough 6 is also connected to the material distribution slope 7. The cross-section of the material distribution slope 7 is inverted V-shaped. The two walls of the machine casing 1 are connected to the two ends of the material distribution slope 7, and the discharge port 8 is provided.

[0029] In practical use, the outer wall of the casing 1 near the discharge port 8 is also provided with a material collection frame 9, and the outer wall of the casing 1 near the material collection frame 9 is also provided with a magnetic suction plate. The material collection frame 9 and the casing 1 are magnetically attracted by the magnetic suction plate, making it convenient and quick to replace the material collection frame and collect the sieved chopsticks for subsequent processes.

[0030] A material-blocking plate 10 and a material-retarding plate 11 are respectively connected to the two sides of the chopstick inlet 3 near the screening chamber 2. The material-retarding plate 11 is positioned close to the rotation direction of the feeding wheel 4. A buffer spring is connected between the material-retarding plate 11 and the inner wall of the screening chamber 2. The buffer spring supports the material-retarding plate 11. The material-retarding plate 11 is hinged to the bottom end of the chopstick inlet 3, thereby flexibly blocking the chopsticks from entering the screening chamber. This ensures that the chopsticks can only be screened by feeding one at a time through the material-retarding trough 5, and are processed in sequence.

[0031] During use, a drive motor 12 is also connected to the outer wall of the housing 1. A synchronous belt is sleeved between the rotating shaft end of the feeding wheel 4, which passes through the outer wall of the housing 1, and the rotating end of the drive motor 12. The drive motor can be selected as a geared motor.

[0032] During use, an opening 13 is provided at the end of the material distribution slope 7 on one side of the housing 1. A baffle plate 14 is hinged in the opening 13 and engages with the opening 13. A finger groove is also provided on the housing to facilitate opening the baffle plate 14 for cleaning and maintenance when the internal space needs to be cleaned.
