Description

Technical Field

[0001] This utility model relates to the technical field of sorting devices, and in particular to a coffee freeze-dried product crushing and sorting device. Background Technology

[0002] Currently, freeze-drying technology is commonly used to dry and dehydrate coffee. During the production of freeze-dried coffee, sorting based on particle size is generally required. Chinese utility model patent CN220329266U discloses a multi-stage coffee cherry sorting device for coffee production. This device includes a main body and a recovery mechanism, with the recovery mechanism located in front of the main body. The main body includes a base plate, a coffee cherry sorting box, a feed pipe, and an observation window. The coffee cherry sorting box is fixedly installed on the upper end of the base plate, the feed pipe is fixedly installed on the upper end of the coffee cherry sorting box, and the observation window is fixedly installed at the rear end of the coffee cherry sorting box. The main body also includes a first movable plate, a second movable plate, and a multi-stage vibrating screen sorting assembly. This multi-stage coffee cherry sorting device, by installing the multi-stage vibrating screen sorting assembly, facilitates multi-stage vibration sorting of coffee cherries by size. During sorting, it effectively prevents clogging of the first and second screens, and the vibration of the coffee cherries causes them to flow, allowing for uniform sieving and sorting, thus enhancing the practicality of the sorting device in use.

[0003] However, the aforementioned multi-stage sorting device cannot crush freeze-dried coffee products, and its function is relatively simple. Therefore, it would be practical to propose a sorting device with crushing function. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a coffee freeze-dried product crushing and sorting device that can crush coffee freeze-dried products and perform multi-stage sorting of the crushed coffee freeze-dried products. It has multiple functions and good practicality.

[0005] This utility model discloses a coffee freeze-dried product crushing and sorting device, comprising a sorting box, a feeding hopper, and multiple sieve plates. The sorting box contains a sorting chamber. The feeding hopper is mounted on the sorting box, with its output end extending into the top of the sorting chamber. Multiple sieve plates are arranged vertically within the sorting chamber, each with a different aperture size. The device also includes a guide plate, a pressure plate, a hinge seat, crushing teeth, and a drive mechanism. The guide plate is inclined and installed below the output end of the feeding hopper. The pressure plate is arranged in a V-shape opposite to the guide plate, located on the left and right sides of the output end of the feeding hopper, respectively. A hinge seat is mounted on the lower end of the pressure plate, hinged to the sorting box. Multiple crushing teeth are arranged on the surface of the pressure plate opposite to the guide plate, located above the multiple sieve plates. The drive mechanism is installed within the sorting chamber of the sorting box and drives the pressure plate. The upper end reciprocates around the hinge seat. During operation, freeze-dried coffee is added to the feed hopper and conveyed to the sorting chamber of the sorting box through the output end of the feed hopper. The freeze-dried coffee falls between the guide plate and the pressure plate and is conveyed downward along the guide plate. During the conveying of the freeze-dried coffee along the guide plate, the drive mechanism drives the upper end of the pressure plate to swing back and forth. When the upper end of the pressure plate swings close to the guide plate, the pressure plate crushes the freeze-dried coffee with multiple crushing teeth in conjunction with the guide plate. The crushed freeze-dried coffee falls onto the screen plate and is sorted by multiple screen plates with different apertures. The multiple screen plates sort the freeze-dried coffee according to particle size from top to bottom in multiple stages. Compared with the existing technology, it can crush freeze-dried coffee and perform multi-stage sorting of the crushed freeze-dried coffee. It has multiple functions and good practicality.

[0006] Preferably, the system also includes a blower, a receiving trough, and a discharging trough. The blower and the receiving trough are installed in the sorting chamber of the sorting box. The air outlet of the blower and the receiving trough are located on the left and right sides below the output end of the feed hopper, respectively. The blower and the receiving trough are located above the guide plate and the pressure plate. The discharging trough is installed on the lower end face of the receiving trough, and the output end of the discharging trough extends into the outside of the sorting box. The air inlet of the blower extends into the outside of the sorting box. The blower is driven by a drive mechanism, so that the air outlet of the blower blows air into the receiving trough. The freeze-dried coffee product output from the feed hopper falls between the blower and the receiving trough, thereby blowing the shriveled particles and light impurities in the freeze-dried coffee product into the receiving trough. The shriveled particles and light impurities that are blown out are discharged from the sorting box through the discharging trough, thereby sorting the freeze-dried coffee product according to its quality before crushing and improving the crushing quality of the freeze-dried coffee product.

[0007] Preferably, the drive mechanism includes a motor, a drive wheel, a driven wheel, a swing arm, and a tie rod. The motor is installed in the sorting chamber of the sorting box. The drive wheel is concentrically mounted on the output shaft of the motor. The driven wheel is rotatably mounted on the bracket. The drive wheel and the driven wheel are connected by a transmission belt. One end of the swing arm is mounted on the central shaft of the driven wheel. The other end of the swing arm is rotatably connected to one end of the tie rod. The other end of the tie rod is rotatably connected to the upper end of the pressure plate. The motor drives the drive wheel to rotate. The drive wheel drives the driven wheel to rotate and the fan to run through the transmission belt. The driven wheel drives the swing arm to rotate. The swing arm drives the upper end of the pressure plate to swing back and forth around the hinge seat through the tie rod, thereby driving the pressure plate and achieving good practicality.

[0008] Preferably, it also includes multiple hinge seats and multiple springs. One end of each of the multiple sieve plates is rotatably connected to the inner wall of one side of the sorting box through multiple hinge seats, and the other end of each of the multiple sieve plates is elastically connected to the inner wall of the other side of the sorting box through multiple springs. The multiple sieve plates are elastically installed in the sorting chamber of the sorting box through multiple hinge seats and multiple springs, so that the multiple sieve plates can move and the coffee freeze-dried powder on the multiple sieve plates can be sieved, thereby improving the filtration and sorting effect.

[0009] Preferably, it also includes a second swing arm and multiple second pull rods. One end of the second swing arm is connected to the output shaft of the motor, and the other end of the second swing arm is rotatably connected to the upper end of a second pull rod. The lower end of the second pull rod is rotatably connected to the uppermost sieve plate. The upper and lower ends of the other multiple second pull rods are respectively rotatably connected to multiple sieve plates. When the output shaft of the motor drives the second swing arm to rotate, the second swing arm drives the multiple second pull rods to vibrate the multiple sieve plates, so that the multiple sieve plates sieve the freeze-dried coffee on them, thereby improving the sorting efficiency.

[0010] Preferably, it also includes multiple gathering troughs and multiple discharge troughs. The center of each of the multiple screen plates is provided with a concave gathering trough, and the center of each of the multiple screen plates is provided with a discharge trough. The multiple discharge troughs extend out of the sorting box. By setting multiple gathering troughs, the freeze-dried coffee on the multiple screen plates gathers towards the center and is conveyed to the outside of the sorting box through the multiple discharge troughs, thereby improving the sorting and discharge effect of the freeze-dried coffee.

[0011] Preferably, the system also includes multiple elastic plates and multiple pusher plates. The upper ends of the multiple elastic plates are connected to the inner wall of the sorting box, and multiple pusher plates are installed at the lower ends of the multiple elastic plates. The lower ends of the multiple pusher plates are in detachable contact with the upper surfaces of the multiple screen plates. When the multiple screen plates vibrate upward, the multiple pusher plates are pushed upward, thereby causing the multiple elastic plates to change from inclined to horizontal. This causes the multiple pusher plates to push the freeze-dried coffee on the multiple screen plates towards the multiple discharge troughs. When the multiple screen plates vibrate downward, the multiple pusher plates disengage from the multiple screen plates, and the multiple elastic plates elastically reset, causing the multiple pusher plates to reset backward. When the multiple screen plates vibrate upward again, the multiple pusher plates push the freeze-dried coffee towards the multiple discharge troughs again, realizing step-by-step pushing of the freeze-dried coffee and improving the discharge efficiency.

[0012] Compared with the prior art, the advantages of this utility model are: it can crush freeze-dried coffee products and perform multi-stage sorting of the crushed freeze-dried coffee products, with multiple functions and good practicality. Attached Figure Description

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0016] like Figures 1 to 6 As shown, a coffee freeze-dried product crushing and sorting device includes a sorting box 1, a feed hopper 2, and multiple sieve plates 3. The sorting box 1 has a sorting chamber inside. The feed hopper 2 is mounted on the sorting box 1, and its output end extends into the top of the sorting chamber. Multiple sieve plates 3 are arranged vertically within the sorting chamber, and the sieve apertures of the multiple sieve plates 3 are different. The device also includes a guide plate 4, a pressure plate 5, a hinge seat 6, crushing teeth 7, and a drive mechanism. The guide plate 4 is inclined and mounted on the feed hopper. Below the output end of hopper 2, the pressure plate 5 and the guide plate 4 are arranged in a V-shape opposite each other. The guide plate 4 and the pressure plate 5 are located on the left and right sides of the output end of the feed hopper 2, respectively. The lower end of the pressure plate 5 is equipped with a hinge seat 6, which is hinged to the sorting box 1. Multiple crushing teeth 7 are arranged on the surface of the pressure plate 5 opposite to the guide plate 4. The pressure plate 5 and the guide plate 4 are located above multiple screen plates 3. The drive mechanism is installed in the sorting chamber of the sorting box 1. The drive mechanism drives the upper end of the pressure plate 5 around the hinge. The receiving seat 6 reciprocates; it also includes a blower 8, a receiving trough 9, and a discharge trough 10. The blower 8 and the receiving trough 9 are installed in the sorting chamber of the sorting box 1. The air outlet of the blower 8 and the receiving trough 9 are located on the left and right sides below the output end of the feed hopper 2, respectively. The blower 8 and the receiving trough 9 are located above the guide plate 4 and the pressure plate 5. The discharge trough 10 is installed on the lower end face of the receiving trough 9, and the output end of the discharge trough 10 extends into the outside of the sorting box 1; the drive mechanism includes a motor 11, a drive wheel 12, and a driven wheel 13. The motor 11 is installed in the sorting chamber of the sorting box 1, with a driving wheel 13, a swing arm 14, and a pull rod 15. The driving wheel 12 is concentrically mounted on the output shaft of the motor 11, and the driven wheel 13 is rotatably mounted on the bracket. The driving wheel 12 and the driven wheel 13 are connected by a transmission belt. One end of the swing arm 14 is mounted on the central shaft of the driven wheel 13, and the other end of the swing arm 14 is rotatably connected to one end of the pull rod 15. The other end of the pull rod 15 is rotatably connected to the upper end of the pressure plate 5.

[0017] During operation, freeze-dried coffee is fed into hopper 2 and conveyed to the sorting chamber of sorting box 1 through the output end of hopper 2. The air inlet of blower 8 extends outside the sorting box 1. Blower 8 is driven by motor 11, causing the air outlet of blower 8 towards receiving trough 9. The freeze-dried coffee output from hopper 2 falls between blower 8 and receiving trough 9, thereby blowing shriveled particles and light impurities in the freeze-dried coffee into receiving trough 9. The shriveled particles and light impurities separated by the air are discharged from sorting box 1 through discharge trough 10. This process sorts the freeze-dried coffee before crushing, allowing high-quality freeze-dried coffee to fall between guide plate 4 and pressure plate 5 and be conveyed downwards along guide plate 4. During the conveying process of the freeze-dried coffee along guide plate 4, motor 11 drives... The driving wheel 12 rotates, which drives the driven wheel 13 to rotate and the fan 8 to run via a transmission belt. The driven wheel 13 drives the swing arm 14 to rotate, and the swing arm 14 drives the upper end of the pressure plate 5 to swing back and forth around the hinge seat 6 via the pull rod 15. When the upper end of the pressure plate 5 swings close to the guide plate 4, the pressure plate 5 crushes the freeze-dried coffee product through multiple crushing teeth 7 in conjunction with the guide plate 4. The crushed freeze-dried coffee product falls onto the sieve plate 3, and the crushed freeze-dried coffee product is sorted in sequence through multiple sieve plates 3 with different apertures. The multiple sieve plates 3 sort the freeze-dried coffee product in multiple stages from top to bottom according to particle size. Compared with the existing technology, it can crush freeze-dried coffee product and sort the crushed freeze-dried coffee product in multiple stages. It has multiple functions and good practicality. Example 2

[0018] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, based on Embodiment 1, it further includes multiple hinge seats 16 and multiple springs 17. One end of each of the multiple screen plates 3 is rotatably connected to one side inner wall of the sorting box 1 via multiple hinge seats 16, and the other end of each of the multiple screen plates 3 is elastically connected to the other side inner wall of the sorting box 1 via multiple springs 17. It also includes a swing arm 18 and multiple pull rods 19. One end of the swing arm 18 is connected to the output shaft of the motor 11, and the other end of the swing arm 18 is rotatably connected to the upper end of a pull rod 19. The lower end of the pull rod 19 is rotatably connected to the uppermost screen plate 3. In addition, the upper and lower ends of multiple tie rods 19 are rotatably connected to multiple screen plates 3; it also includes multiple gathering grooves 20 and multiple discharge grooves 21. The middle of each screen plate 3 is provided with a concave gathering groove 20, and the middle of each screen plate 3 is provided with a discharge groove 21. The discharge grooves 21 extend out of the outside of the sorting box 1; it also includes multiple elastic plates 22 and multiple pusher plates 23. The upper end of each elastic plate 22 is connected to the inner wall of the sorting box 1, and the lower end of each elastic plate 22 is provided with multiple pusher plates 23. The lower end of each pusher plate 23 is in detachable contact with the upper surface of each screen plate 3.

[0019] Multiple sieve plates 3 are elastically mounted in the sorting chamber of the sorting box 1 via multiple hinge seats 16 and multiple springs 17, allowing the sieve plates 3 to move. When the output shaft of the motor 11 drives the swing arm 18 to rotate, the swing arm 18 drives the multiple sieve plates 3 to vibrate via multiple pull rods 19, causing the multiple sieve plates 3 to sieve the freeze-dried coffee products on them. By setting multiple gathering grooves 20, the freeze-dried coffee products on the multiple sieve plates 3 are gathered towards the center. When the multiple sieve plates 3 vibrate upward, the multiple pusher plates 23 are pushed upward, thereby causing the multiple elastic plates 22 to move from an inclined direction. The horizontal transition causes multiple pusher plates 23 to push the freeze-dried coffee products on multiple sieve plates 3 toward multiple discharge troughs 21. When the multiple sieve plates 3 vibrate downwards, the multiple pusher plates 23 disengage from the multiple sieve plates 3, and the multiple elastic plates 22 elastically reset, causing the multiple pusher plates 23 to reset backwards. When the multiple sieve plates 3 vibrate upwards again, the multiple pusher plates 23 push the freeze-dried coffee products toward the multiple discharge troughs 21 again, realizing the step-by-step pushing of the freeze-dried coffee products, and conveying them to the outside of the sorting box 1 through the multiple discharge troughs 21, thereby improving the sorting and discharge efficiency of the freeze-dried coffee products.

[0020] like Figures 1 to 7As shown, this utility model discloses a coffee freeze-dried product crushing and sorting device. During operation, the coffee freeze-dried product is first added to the feed hopper 2 and conveyed to the sorting chamber of the sorting box 1 through the output end of the feed hopper 2. The blower 8 is driven by a drive mechanism, causing its outlet to blow air into the receiving trough 9. The coffee freeze-dried product output from the feed hopper 2 falls between the blower 8 and the receiving trough 9, thereby blowing shriveled particles and light impurities from the coffee freeze-dried product into the receiving trough 9. The shriveled particles and light impurities separated by the air are then discharged from the sorting box 1 through the discharge trough 10. This allows for the sorting of the coffee freeze-dried product before crushing. The high-quality coffee freeze-dried product then falls between the guide plate 4 and the pressure plate 5 and is conveyed downwards along the guide plate 4. During the conveying process along the guide plate 4, the drive mechanism drives the upper end of the pressure plate 5 to swing back and forth. When the upper end of the pressure plate 5 swings close to the guide plate 4, the pressure plate 5 passes through multiple... The crushing teeth 7, in conjunction with the guide plate 4, crush the freeze-dried coffee. The crushed freeze-dried coffee falls onto the sieve plate 3, and then passes through multiple sieve plates 3 with different apertures to sort the crushed freeze-dried coffee in stages according to particle size. When the multiple sieve plates 3 vibrate upward, the multiple pusher plates 23 are pushed upward, thereby causing the multiple elastic plates 22 to change from inclined to horizontal. This causes the multiple pusher plates 23 to push the freeze-dried coffee on the multiple sieve plates 3 towards the multiple discharge troughs 21. When the multiple sieve plates 3 vibrate downward, the multiple pusher plates 23 disengage from the multiple sieve plates 3, and the multiple elastic plates 22 elastically reset, causing the multiple pusher plates 23 to reset backward. When the multiple sieve plates 3 vibrate upward again, the multiple pusher plates 23 push the freeze-dried coffee towards the multiple discharge troughs 21 again. Finally, the freeze-dried coffee is pushed in a step-by-step manner and discharged from the sorting box 1 through the multiple discharge troughs 21.

[0021] The main functions achieved by this utility model are: 1. It can crush freeze-dried coffee products and perform multi-stage sorting of the crushed freeze-dried coffee products. It has multiple functions and good practicality. 2. It can blow the shriveled particles and light impurities in the freeze-dried coffee into the receiving trough 9 by air separation, and discharge the shriveled particles and light impurities separated by air through the discharge trough 10 into the sorting box 1, so as to sort the freeze-dried coffee into superior and inferior products before crushing, thereby improving the crushing quality of the freeze-dried coffee. 3. It can drive multiple sieve plates 3 to vibrate, so that the multiple sieve plates 3 can sieve the freeze-dried coffee on them, thereby improving the sorting efficiency. 4. The freeze-dried coffee products on multiple screen plates 3 are pushed in a step-by-step manner by multiple elastic plates 22 and multiple pusher plates 23 to improve the discharge efficiency.

[0022] The coffee freeze-dried product crushing and sorting device of this utility model has common mechanical installation, connection and setting methods, and can be implemented as long as it can achieve its beneficial effect. The sorting box 1, feeding hopper 2, sieve plate 3, guide plate 4, pressing plate 5, hinge seat 1 6, crushing teeth 7, fan 8, motor 11, driving wheel 12, driven wheel 13, hinge seat 2 16, spring 17, elastic plate 22 and pushing plate 23 of the coffee freeze-dried product crushing and sorting device of this utility model are purchased from the market.
