Description

Technical Field

[0001] The invention belongs to the technical field of grass jelly processing equipment, and in particular relates to a grass jelly screening and cleaning device. Background Art

[0002] Xiancao, also known as Xianrencao and Liangfencao, is an annual herbaceous plant of the genus Xiancao in the Lamiaceae family. It is an important plant resource for both medicine and food. The dried sample of Xianrencao contains about 70% carbohydrates, a small amount of protein, fat, pigment, etc., and also contains a large amount of mineral elements. Xiancao is widely used in medicine and has the functions of clearing away heat and relieving heat and promoting diuresis. There are many related products on the market, including: instant xiancao jelly powder, xiancao health tea, xiancao cola beverage, instant xiancao, extracted coffee pigment, etc.

[0003] Before boiling, the grass jelly needs to be screened and cleaned to remove impurities and dust mixed in it. Traditional screening equipment usually uses a single vibration method for screening. Since the grass jelly raw materials are leaves and stems mixed together, some impurities will be lifted or stuck in the middle of the raw materials, and the screening and purification effect is not good. In addition, conventional cleaning methods include immersion cleaning and spray cleaning. Immersion cleaning is to immerse the grass jelly in a cleaning cylinder for stirring and cleaning. The cleaning effect is good, but it can only be done in batches, requiring a lot of manual labor for transportation, and each batch needs to be changed after cleaning, which consumes a lot of water. Spray cleaning consumes less water, but the cleaning effect is not good. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a herbal jellyfish screening and cleaning device, in which a flipping mechanism is arranged on the vibration screening device to improve the screening effect, and ultrasonic cleaning is combined with spray cleaning to reduce water consumption and manpower during the cleaning process.

[0005] In order to achieve the above-mentioned purpose, the solution adopted by the present invention is: a fairy grass screening and cleaning device, including a screening mechanism, an ultrasonic cleaning mechanism and a spray cleaning mechanism, the ultrasonic cleaning mechanism is arranged between the screening mechanism and the spray cleaning mechanism; the screening mechanism includes a base, a sieve plate, a vibration generating device, a baffle, a flip bucket and a flip assembly, the sieve plate is tilted on the base, the vibration generating device is connected to the sieve plate, and the vibration generating device is used to drive the sieve plate to vibrate so that the material in the sieve plate moves along the length direction of the sieve plate; the two flip assemblies are symmetrically arranged on both sides of the sieve plate, and the flip assembly includes a guide rod, a slider, a fixed block, a first connecting rod and a second connecting rod, the guide rod is arranged along the length direction of the sieve plate and is fixedly connected to the sieve plate, the slider is sleeved on the guide rod, and the fixed block is fixedly arranged on the The guide rod, the fixed end of the first connecting rod is hinged to the fixed block, one end of the second connecting rod is hinged to the sliding block, and the other end of the second connecting rod is hinged to the free end of the first connecting rod; the baffle is arranged at the upstream end of the tipping bucket, the tipping bucket is arranged above the sieve plate and fixedly connected to the second connecting rod, the tipping bucket is a triangular prism, the tipping bucket includes a first side plate, a second side plate and an end plate, the first side plate and the second side plate are both provided with sieve holes, the end plate is fixedly arranged on the ends of the first side plate and the second side plate, when the sliding block moves to the first preset position, the first side plate is close to the sieve plate, at this time, the material at the upstream end of the tipping bucket can enter the tipping bucket, when the sliding block moves to the second preset position, the second side plate is close to the sieve plate, at this time, the material at the upstream end of the tipping bucket is blocked by the baffle.

[0006] By adopting the above scheme, on the one hand, the raw materials can be made more fluffy and the gaps can be increased to facilitate the falling of impurities during the vibration process. On the other hand, the impurities that are lifted or stuck in the middle of the stems and leaves can be made to lose support, so that more impurities can be discharged from the raw materials under the action of gravity, thereby improving the screening and purification effect of the herb.

[0007] Furthermore, the ultrasonic cleaning mechanism includes a limit seat, a cleaning tank and a transfer mechanism. The transfer mechanism is cylindrical in shape. The transfer mechanism rotates around its own central axis under the action of external force. The peripheral wall of the transfer mechanism is provided with a plurality of accommodating grooves. The plurality of accommodating grooves are arranged along the circumference of the transfer mechanism. The end of the transfer mechanism is provided with a water flow hole connected to the accommodating groove. An ultrasonic generator for cleaning materials is provided in the cleaning tank. The inner side of the cleaning tank is provided with a first arc surface that matches the peripheral wall of the transfer mechanism. The limit seat is fixedly arranged on the top of the cleaning tank. The side of the limit seat close to the transfer mechanism is provided with a second arc surface that matches the peripheral wall of the transfer mechanism. The first arc surface and the second arc surface are both close to the peripheral wall of the transfer mechanism.

[0008] After being discharged from the screening mechanism, the material falls into the receiving groove on the top of the transfer mechanism. Since the first curved surface and the second curved surface are close to the peripheral wall of the transfer mechanism, the first curved surface and the second curved surface have a supporting effect on the material in the receiving groove. The material can enter the cleaning tank and be immersed in water as the transfer mechanism rotates. The equipment has a high degree of automation and does not require a large amount of manpower for transfer, which is convenient for enterprise management and stabilizes production capacity.

[0009] Furthermore, the spray cleaning mechanism includes a conveyor belt and a nozzle, and the nozzle is arranged above the conveyor belt. After the material is discharged from the cleaning tank, it directly falls onto the conveyor belt, and then the nozzle sprays and washes away the stains on the surface of the raw material to achieve thorough cleaning.

[0010] Furthermore, the sliders of the two flip assemblies are connected by a third connecting rod, and the screening mechanism is provided with a driving cylinder, the cylinder shaft of the driving cylinder is connected to the third connecting rod, and the driving cylinder is used to drive the slider to slide along the guide rod. The cylinder body of the driving cylinder is fixedly arranged at the bottom of the sieve plate, and the cylinder shaft end of the driving mechanism is connected to the midpoint of the third connecting rod. In this way, the synchronous movement of the two sliders can be well ensured, the transmission structure of the equipment can be simplified, and jamming due to inconsistent movement can be avoided.

[0011] Furthermore, the tipping assembly further includes a lifting seat, which is fixedly connected to the third connecting rod, a guiding inclined surface is provided on the top of the lifting seat, a clearance hole corresponding to the baffle is provided on the sieve plate, the baffle extends into the clearance hole, and the bottom of the baffle abuts against the top of the lifting seat. When the lifting seat approaches the baffle, the bottom of the baffle slides along the guiding inclined surface, and then the baffle is lifted by the lifting seat, so that the baffle is blocked at the upstream end of the tipping bucket. A driving mechanism can be used to simultaneously drive the tipping bucket to tip and the baffle to lift, thereby reducing the production cost of the equipment and ensuring the consistency of the action of the tipping bucket and the baffle. When the tipping bucket rotates and rises, the baffle is also lifted to block the material, ensuring that all the fairy grass passes through the tipping bucket and the screening effect is ensured.

[0012] Furthermore, a horizontal plate corresponding to the baffle is provided on the top of the sieve plate, and when the baffle plate moves to the highest point, the top of the baffle plate abuts against the horizontal plate. In this way, when the baffle plate rises, the grass jelly just located on the top of the baffle plate will be clamped between the baffle plate and the horizontal plate and fixed, so as to avoid falling from the sieve plate during the vibration process, thereby reducing the loss of raw materials.

[0013] Furthermore, a roller is provided at the bottom of the baffle, and further, a limiting groove matched with the roller is provided at the top of the lifting seat, which can improve the stability and smoothness of the transmission between the baffle and the lifting seat, improve the reliability of the equipment, and reduce the failure rate.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) A turning assembly and a turning bucket are arranged on the sieve plate, and the material is turned by the turning bucket. This can make the raw material more fluffy and increase the gap, which is convenient for impurities to fall during the vibration process. On the other hand, the turning can make the impurities that are lifted or stuck in the middle of the stems and leaves lose their support, so that more impurities are discharged from the raw material under the action of gravity, thereby improving the screening and purification effect of the herbal jelly;

[0016] (2) After being discharged from the screening mechanism, the material falls into the containing tank on the top of the transfer mechanism, and then enters the cleaning tank driven by the transfer mechanism and is immersed in water. The dust attached to its surface is shaken off by ultrasound, and finally the stains on the surface of the raw material are washed away by spraying. The ultrasonic cleaning and spray cleaning are combined. Compared with the traditional immersion stirring cleaning, the ultrasonic cleaning effect is better and the cleaning time is shorter. There is no need to change water frequently, the water consumption is small, the equipment has a high degree of automation, and does not require a lot of manpower, which is convenient for enterprise management and stabilizes production capacity.

[0029] The two flipping assemblies 16 are symmetrically arranged on both sides of the sieve plate 12, and the flipping assemblies 16 include a guide rod 161, a slider 162, a fixed block 163, a first connecting rod 164 and a second connecting rod 165. The guide rod 161 is arranged along the length direction of the sieve plate 12 and is fixedly connected to the sieve plate 12. The slider 162 is sleeved on the guide rod 161, and the fixed block 163 is fixed on the guide rod 161. The fixed end of the first connecting rod 164 is hinged to the fixed block 163, one end of the second connecting rod 165 is hinged to the slider 162, and the other end of the second connecting rod 165 is hinged to the free end of the first connecting rod 164.

[0030] The baffle 14 is arranged at the upstream end of the tipping bucket 15. The tipping bucket 15 is arranged above the sieve plate 12 and is fixedly connected to the second connecting rod 165. The tipping bucket 15 is a triangular prism. The tipping bucket 15 includes a first side plate 151, a second side plate 152 and an end plate 153. The first side plate 151 and the second side plate 152 are both provided with sieve holes (not shown in the figure). The end plate 153 is fixedly arranged at the ends of the first side plate 151 and the second side plate 152. The end plate 153 is located between the two retaining edges 123 of the sieve plate 12, and the end plate 153 is close to the retaining edges 123.

Then the slider 162 moves toward the baffle 14, and the tipping bucket 12 rotates toward the fixed block 163, as shown in FIG. Figure 5 As shown, when the slider 162 moves to the second preset position, the second side plate 152 is close to the sieve plate 12, and the baffle 14 is fully raised. The material at the upstream end of the tipping bucket 15 is blocked by the baffle 14, and the material in the tipping bucket 15 is discharged under vibration.

[0032] Please refer to Figure 6 In this embodiment, the sliders 162 of the two flip assemblies 16 are connected by a third connecting rod 17, and the screening mechanism 1 is provided with a driving cylinder 4, the cylinder body of the driving cylinder 4 is fixedly arranged at the bottom of the sieve plate 12, and the cylinder shaft of the driving cylinder 4 is connected to the midpoint of the third connecting rod 17, and the driving cylinder 4 is used to drive the slider 162 to slide along the guide rod 161.

[0033] In some other embodiments, such as Figure 3 and Figure 6As shown, the turning assembly 16 also includes a lifting seat 18, which is fixedly connected to the third connecting rod 17. A guide slope 181 is provided on the top of the lifting seat 18. A clearance hole 121 corresponding to the baffle 14 is provided on the sieve plate 12. The baffle 14 extends into the clearance hole 121, and the bottom of the baffle 14 abuts against the top of the lifting seat 18. When the lifting seat 18 approaches the baffle 14, the bottom of the baffle 14 slides along the guiding slope 181, and then the baffle 14 is lifted by the lifting seat 18, so that the baffle 14 is blocked at the upstream end of the turning bucket 15. A driving mechanism can be used to simultaneously drive the turning bucket 15 to turn and the baffle 14 to rise and fall, thereby reducing the production cost of the equipment and ensuring the consistency of the movements of the turning bucket 15 and the baffle 14. When the turning bucket 15 rotates and rises, the baffle 14 is also lifted to block the material, ensuring that all the fairy grass passes through the turning bucket 15 and the screening effect is guaranteed. A transverse plate 122 corresponding to the baffle 14 is provided at the top of the sieve plate 12. When the baffle 14 moves to the highest point, the top of the baffle 14 abuts against the transverse plate 122.
