Description

Technical Field

[0001] The present invention belongs to the technical field of dietary raw material processing, and more specifically, relates to a healthy dietary raw material processing device and a processing method. Background Art

[0002] Healthy dietary raw materials refer to those ingredients that are rich in nutrients and help maintain human health. Common healthy dietary raw materials include various grains, such as rice, wheat, corn, almonds, walnuts, cashews, etc. Some healthy dietary raw materials need to be peeled. The main reason is that the skin of some ingredients cannot be eaten, or is relatively tough and not easy to be digested by the human body, such as the skin of beans. After removing the skin, the nutrients can be more easily absorbed by the human body and the burden on the gastrointestinal tract can be reduced.

[0003] At present, an existing device (such as announcement number: CN219644971U) discloses a "bitter almond peeling machine". The machine drives two first peeling rollers and two second peeling rollers to rotate by setting gears of different sizes, so that the two first peeling rollers and the two second peeling rollers rotate in opposite directions at differential speeds, thereby not only squeezing the almonds but also rubbing the almonds, so that the pulp and the shell are separated more thoroughly.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: during operation, the machine mainly relies on the peeling roller to perform the peeling operation. However, its peeling direction is relatively single, and there is a lack of structural design that can adjust the discharge density, which makes it difficult for the material put in from the material guide trough to fully and fully contact with the peeling roller, thereby affecting the peeling efficiency and effect. In addition, some materials need to be heat treated during peeling to improve the processing quality. However, when this machine is in operation, there is a lack of preheating of the material. The material that has not been preheated is directly peeled, which is very likely to result in poor peeling quality. The peeling quality is insufficient and needs to be improved.

[0012] Preferably, a discharge hopper is fixedly installed at the lower end of the pretreatment box, and the discharge hopper is located below the sponge set. The upper end of the base is respectively provided with a first conveyor bracket assembly and a second conveyor bracket assembly, and the first conveyor bracket assembly and the second conveyor bracket assembly are both in an inverted trapezoidal shape as a whole.

[0013] Preferably, a first conveyor belt is provided on the inner side of the first conveyor support assembly, and a second conveyor belt is provided on the inner side of the second conveyor support assembly.

[0015] A processing method of a healthy dietary raw material processing device comprises the following steps:

[0016] S1: The staff connects the conveying pipeline to the external steam supply unit, then puts the processed material into the feed hopper and starts the two motors in forward and reverse rotation. The motor drives the peeling roller to rotate in the pretreatment box, and drives the eccentric wheel to rotate. The eccentric wheel rubs against the slider through the slide groove. Under the constraint of the limit bar, the sliding sleeve slides vertically along the limit bar. The sliding sleeve pulls the valve control rod through the first telescopic connecting rod, opens the flap valve, and allows the material to enter the steam treatment hopper;

[0017] S2: When the sliding sleeve moves upward, it will drive the L-shaped rod to apply radial force to the steam nozzle through the second telescopic connecting rod, causing the steam nozzle to rotate around the rotation axis in the storage tank. At the same time, the sliding sleeve enters the special-shaped slot and triggers the first stroke switch, opening the external steam valve. Steam is ejected from the steam nozzle through the conveying pipe to heat treat the material. After pre-peeling, the material is discharged from the discharge hopper to the first conveyor belt. At the same time, the eccentric wheel continues to rotate to make the sliding sleeve reciprocate, thereby controlling the intermittent opening and closing of the flap valve and the reciprocating swing of the steam nozzle.

[0018] S3: The material after steam treatment enters the peeling roller room, where the peeling roller performs pre-peeling. The sponge set on its surface absorbs moisture from the material surface. When the peeling roller rotates, the sponge set contacts the scraper, scraping the moisture to the collection plate and then discharging it through the water trough and water pipe.

[0019] S4: The staff starts the motors on the first conveyor support assembly and the second conveyor support assembly to rotate forward and reverse respectively, and turns on the electric push rod. At this time, the first conveyor belt and the second conveyor belt will rotate forward and reverse respectively. At the same time, the electric push rod will push the first conveyor support assembly to move longitudinally, causing the limit block to slide along the limit groove. The rack engages with the gear in the rectangular groove, driving the two conveyor support assemblies to move in an interlaced manner. The wear-resistant strips on the first conveyor belt and the second conveyor belt will synchronously peel the material longitudinally and transversely.

[0020] S5: When the limit block reaches the end of the limit slot and triggers the second limit switch, the electric push rod retracts, driving the first conveyor bracket assembly to reset, and the rack and gear engage in reverse, causing the two conveyor bracket assemblies to slide in reverse and staggered manner. This reciprocating motion completes the peeling.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, by setting a multifunctional structure, reciprocating intermittent feeding and heat treatment can be achieved when pre-treating the material in the pre-treatment box. The reciprocating intermittent feeding makes the material evenly distributed in a limited space, avoids accumulation to form a treatment dead corner, and makes the subsequent heat treatment more balanced. For example, the granular material can be fully penetrated by the heat medium. The heat treatment stage is synchronized with the intermittent feeding. The material can be quickly heated as soon as it enters. The two operate synchronously to form an efficient cycle, thereby improving the peeling quality.

[0023] In the present invention, by arranging a first stroke switch inside the special-shaped groove, the sliding sleeve can drive the valve control rod to rotate through the first telescopic connecting rod to open the flap valve to release the material. The sliding sleeve will move upward into the special-shaped groove and hit the contact of the first stroke switch. The first stroke switch will open the valve for external steam transmission, allowing the steam to be discharged from the steam nozzle through the delivery pipe, thereby achieving the simultaneous implementation of material release and steam heat treatment, improving the efficiency of material processing, avoiding the time wasted for the material to wait for steam supply, and improving energy saving.

[0024] In the present invention, by arranging an eccentric wheel, when the motor drives the peeling roller to rotate in the pretreatment box, the eccentric wheel will be driven to rotate synchronously, so that the slide groove on the eccentric wheel actively generates friction with the slider, and under the limiting action of the limit bar, the sliding sleeve will slide vertically on the limit bar, and the movement of the sliding sleeve will pull the valve control rod through the first telescopic connecting rod, so that the flap valve can be automatically opened intermittently, thereby completing the quantitative transportation of the material, ensuring that the amount of material entering the processing link each time is stable, making the subsequent steam heat treatment and peeling treatment more controllable, avoiding the influence of the processing effect due to excessive or insufficient feeding, and improving the peeling effect;

[0025] In the present invention, by providing an eccentric wheel, when the sliding sleeve moves upward, the sliding sleeve will synchronously drive the L-shaped rod to move together, so that the L-shaped rod exerts a radial force on the steam nozzle through the second telescopic connecting rod, causing the steam nozzle to rotate in the storage tank with the rotating axis as the center. At the same time, since the flap valve is also opened during the upward movement of the sliding sleeve, it can be ensured that the quantitatively conveyed material is immediately covered and heat-treated by the steam sprayed by the rotating steam nozzle as soon as it enters the steam processing bucket, thereby ensuring the subsequent peeling effect;

[0026] In the present invention, when the steam-treated material enters between the peeling rollers, the peeling rollers will pre-peel the material. At the same time, the sponge group on its surface will absorb the moisture on the surface of the material. When the peeling rollers rotate, the sponge group will actively contact the scraper to scrape the moisture to the collection plate, and then discharge it through the water trough and water pipe, thereby avoiding the problem of moisture accumulation inside the device causing damage.

[0027] In the present invention, by starting the electric push rod, its output shaft pushes the first conveyor support assembly to move longitudinally, driving the limit block to slide in the limit groove, and at the same time the rack engages with the gear in the rectangular groove; the gear is driven by meshing with the rack on the second conveyor support assembly, so that the first conveyor support assembly and the second conveyor support assembly perform staggered longitudinal sliding, so that the wear-resistant strips of the first conveyor belt and the second conveyor belt synchronously perform longitudinal and transverse peeling processing on the material. When the limit block moves to the end of the limit groove and triggers the second limit switch, the electric push rod retracts and drives the first conveyor support assembly to reset. At this time, the rack and the gear engage in reverse, and the first conveyor support assembly and the second conveyor support assembly perform reverse staggered longitudinal sliding. This two-way synchronous peeling mechanism significantly improves the thoroughness of peeling through multi-dimensional processing, reduces residual outer skin, and ensures the consistency of finished product quality.

[0047] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0048] See also Figure 1 - Figure 18 The present invention provides a healthy dietary raw material processing device, comprising a base 11, a shell 12 is provided at the upper end of the base 11, a pre-processing box 13 is provided at the upper end of the shell 12, a feed hopper 14 is provided at the upper end of the pre-processing box 13, and the feed hopper 14 is communicated with the interior of the base 11;

[0049] A multifunctional structure is fixedly installed at the lower end of the feed hopper 14;

[0050] The multifunctional structure includes a flap valve 15, a steam treatment bucket 16 is fixed to the lower end of the flap valve 15, a valve control rod 21 is provided on the side wall of the flap valve 15, and the valve control rod 21 on the flap valve 15 can control the valve inside the flap valve 15 (the flap valve 15 is a prior art and mainly consists of a valve, a rotating shaft, and the valve control rod 21) to rotate. Motors 17 are symmetrically fixedly mounted on the side wall of the base 11, and peeling rollers 18 are fixedly mounted on the output shafts of the two motors 17. The two peeling rollers 18 are both located inside the base 11 and rotatably installed. The roller surfaces of the two peeling rollers 18 are provided with sponge sets 19. A special-shaped groove 22 is opened through the inside of the base 11. The special-shaped groove 22 is parallel to the flap valve 15 and located above the flap valve 15. A first stroke switch 23 is fixedly mounted inside the special-shaped groove 22;

[0051] By providing a multifunctional structure, when pre-treating the material in the pre-treatment box 13, reciprocating intermittent feeding and heat treatment can be achieved. The reciprocating intermittent feeding makes the material evenly distributed in a limited space, avoiding accumulation to form treatment dead corners, and making the subsequent heat treatment more balanced. For example, granular materials can be fully penetrated by the heat medium. The heat treatment stage is synchronized with the intermittent feeding, and the material can be quickly heated as soon as it enters. The synchronous operation of the two forms an efficient cycle, thereby improving the peeling quality.

[0052] By providing the special-shaped groove 22, it is ensured that the sliding sleeve 28 can smoothly drive the valve control rod 21 to rotate through the first telescopic connecting rod 29 to open the flap valve 15;

[0053] By arranging a first travel switch 23 inside the special-shaped groove 22 (the travel switch is an existing technology, mainly used to complete subsequent operations triggered by special positions in industrial control to complete the process of automated production), the sliding sleeve 28 can drive the valve control rod 21 to rotate through the first telescopic connecting rod 29 to open the flap valve 15 to release the material. The sliding sleeve 28 will move upward into the special-shaped groove 22 and hit the contact of the first travel switch 23. The first travel switch 23 will open the valve for external steam transmission, allowing the steam to be discharged from the steam nozzle 33 through the delivery pipe 34, thereby realizing the simultaneous material release and steam heat treatment, improving the efficiency of material processing, avoiding the time wasted for materials waiting for steam supply, and improving energy saving.

[0054] A limit strip 24 is fixedly mounted on the inner wall of the base 11, an eccentric wheel 25 is fixedly mounted on the circumferential surface of one of the two peeling rollers 18, and a slide groove 26 is symmetrically opened on the circumferential surface of the eccentric wheel 25. A slider 27 is slidably mounted between the two slide grooves 26, and a sliding sleeve 28 is fixedly mounted on the side wall of the slider 27. The sliding sleeve 28 is slidably mounted on the limit strip 24, and the sliding sleeve 28 is located below the special-shaped groove 22. The sliding sleeve 28 is parallel to the contact of the first travel switch 23, and a first telescopic connecting rod 29 is rotatably mounted between the end of the valve control rod 21 and the sliding sleeve 28.

[0055] By setting the eccentric wheel 25, when the motor 17 drives the peeling roller 18 to rotate in the pretreatment box 13, the eccentric wheel 25 will be driven to rotate synchronously, so that the slide groove 26 on the eccentric wheel 25 will actively generate friction with the slider 27. Under the limiting action of the limit bar 24, the sleeve 28 will slide vertically on the limit bar 24. The movement of the sleeve 28 will pull the valve control rod 21 through the first telescopic connecting rod 29, so that the flap valve 15 can be automatically opened intermittently, thereby completing the quantitative transportation of the material, ensuring the stability of the amount of material entering the processing link each time, making the subsequent steam heat treatment and peeling treatment more controllable, avoiding the impact of excessive or insufficient feed on the processing effect, and improving the peeling effect.

[0056] A storage groove 31 is formed inside the steam treatment bucket 16. A rotating shaft 32 is rotatably mounted inside the storage groove 31. A steam nozzle 33 is fixedly mounted on the upper end of the rotating shaft 32. Delivery pipes 34 are symmetrically provided on the side walls of the steam nozzle 33. Both delivery pipes 34 are exposed and slidably mounted outside the pretreatment box 13. An L-shaped rod 35 is fixedly mounted on the side wall of the sliding sleeve 28. A second telescopic connecting rod 36 is rotatably mounted between the L-shaped rod 35 and the steam nozzle 33.

[0057] By setting the eccentric wheel 25, when the sliding sleeve 28 moves upward, the sliding sleeve 28 will synchronously drive the L-shaped rod 35 to move together, so that the L-shaped rod 35 applies a radial force to the steam nozzle 33 through the second telescopic connecting rod 36, so that the steam nozzle 33 rotates in the storage groove 31 with the rotating shaft 32 as the center. At the same time, since the flap valve 15 will also open during the rising process of the sliding sleeve 28, it can be ensured that the quantitatively conveyed material is immediately covered and heat-treated by the steam sprayed by the rotating steam nozzle 33 as soon as it enters the steam processing bucket 16, thereby ensuring the subsequent peeling effect.

[0058] The inner wall of the base 11 is symmetrically fixed with scrapers 37, and the two scrapers 37 are respectively located on both sides of the sponge set 19 and fit together. A water diversion trough 38 is symmetrically opened through the inner wall of the base 11, and a collecting plate 39 is symmetrically fixedly installed on the inner wall of the base 11. The two collecting plates 39 are both located below the water diversion trough 38. The two collecting plates 39 are both located below the scrapers 37. Water diversion pipes 41 are provided on the side walls of the two water diversion troughs 38. The two scrapers 37 can scrape the water absorbed by the sponge set 19 into the collecting plates 39 so that the water flows through the collecting plates 39 into the water diversion trough 38 and is discharged from the water diversion pipes 41.

[0059] When the steam-treated material enters between the peeling rollers 18, the peeling rollers 18 will pre-peel the material. At the same time, the sponge set 19 on its surface will absorb moisture on the surface of the material. When the peeling rollers 18 rotate, the sponge set 19 will actively contact the scraper 37 to scrape the moisture to the collection plate 39, and discharge it through the water trough 38 and the water pipe 41, so as to avoid the problem of moisture accumulating inside the device and causing damage.

[0060] A discharge hopper 56 is fixedly installed at the lower end of the pretreatment box 13, and the discharge hopper 56 is located below the sponge set 19. The upper end of the base 11 is respectively provided with a first conveyor bracket assembly 42 and a second conveyor bracket assembly 44, and the first conveyor bracket assembly 42 and the second conveyor bracket assembly 44 (the brackets of the first conveyor bracket assembly 42 and the second conveyor bracket assembly 44 are overall inverted trapezoidal, which are mainly composed of brackets, motors, and rollers) are all inverted trapezoidal as a whole. A first conveyor belt 43 is provided on the inner side of the first conveyor bracket assembly 42, and a second conveyor belt 45 is provided on the inner side of the second conveyor bracket assembly 44. Part of the second conveyor belt 45 is located above the first conveyor bracket assembly 42. Limiting grooves 46 are symmetrically provided inside the base 11, and limiting blocks 47 are slidably installed inside the two limiting grooves 46. The two limiting blocks 47 are respectively fixed to the first conveyor bracket assembly 42 and the second conveyor bracket assembly 44, and the lengths of the two limiting blocks 47 are both less than the length of the limiting grooves 46.

[0061] By setting up the first conveyor support assembly 42 and the second conveyor support assembly 44, the pre-treated material can be discharged onto the first conveyor belt 43 through the discharge hopper 56, so that it can be subjected to horizontal peeling treatment by rotating in opposite directions through the first conveyor belt 43 and the second conveyor belt 45.

[0062] A rectangular groove 48 is provided inside the base 11, and a gear 49 is rotatably installed inside the rectangular groove 48. The lower ends of the first conveyor support assembly 42 and the second conveyor support assembly 44 are fixedly installed with a rack 51. The two racks 51 are both located in the rectangular groove 48 and are slidably installed. The lengths of the two racks 51 are both less than the length of the rectangular groove 48. The two racks 51 are meshed with the gear 49. An electric push rod 52 is fixedly installed on the upper end of the base 11. The output shaft of the electric push rod 52 is fixedly installed with the first conveyor support assembly 42. The electric push rod 52 can push the first conveyor support assembly 42. The rack assembly 42 drives the rack 51 to slide inside the gear 49 so that the gear 49 rotates and engages with the rack 51 on the second conveyor bracket assembly 44, so that the first conveyor bracket assembly 42 and the second conveyor bracket assembly 44 slide alternately in the longitudinal direction. The two limit grooves 46 are symmetrically embedded with second limit switches 53, and the two second limit switches 53 are adapted to the limit blocks 47. The surfaces of the first conveyor belt 43 and the second conveyor belt 45 are provided with a plurality of wear-resistant strips 54, and each of the wear-resistant strips 54 has a plurality of through slots 55 extending therethrough.

[0063] By starting the electric push rod 52, its output shaft pushes the first conveyor support assembly 42 to move longitudinally, driving the limit block 47 to slide in the limit groove 46, and at the same time, the rack 51 engages with the gear 49 in the rectangular groove 48; the gear 49 engages with the rack 51 on the second conveyor support assembly 44 to transmit the first conveyor support assembly 42 and the second conveyor support assembly 44 to perform staggered longitudinal sliding, so that the wear-resistant strips 54 of the first conveyor belt 43 and the second conveyor belt 45 synchronously perform longitudinal and transverse peeling processing on the material. When the limit block 47 moves to the end of the limit groove 46 and triggers the second limit switch 53, the electric push rod 52 retracts and drives the first conveyor support assembly 42 to reset. At this time, the rack 51 engages with the gear 49 in the opposite direction, and the first conveyor support assembly 42 and the second conveyor support assembly 44 perform reverse staggered longitudinal sliding. This two-way synchronous peeling mechanism significantly improves the thoroughness of peeling through multi-dimensional processing, reduces residual outer skin, and ensures the consistency of finished product quality.

[0064] The entire device is controlled by an external PLC controller, the delivery pipe 34 is connected to an external steam supply unit, and the first travel switch 23 can control an external electric control valve for supplying the delivery pipe 34 .

[0065] In the first step, the staff connects the conveying pipe 34 to the external steam supply unit, then puts the processed material into the feed hopper 14 and synchronously starts the two motors 17 for forward and reverse rotation respectively. The motor 17 drives the peeling roller 18 to rotate in the pretreatment box 13, and drives the eccentric wheel 25 to rotate. The eccentric wheel 25 rubs against the slider 27 through the slide groove 26. Under the constraint of the limit bar 24, the sliding sleeve 28 slides vertically along the limit bar 24. The sliding sleeve 28 pulls the valve control rod 21 through the first telescopic connecting rod 29, opening the flap valve 15 and allowing the material to enter the steam treatment hopper 16;

[0066] In the second step, when the sliding sleeve 28 moves upward, it drives the L-shaped rod 35 to apply a radial force to the steam nozzle 33 through the second telescopic link 36, causing the steam nozzle 33 to rotate around the rotation axis 32 in the storage groove 31. At the same time, the sliding sleeve 28 enters the special-shaped groove 22 and triggers the first travel switch 23, opening the external steam valve. Steam is ejected from the steam nozzle 33 through the conveying pipe 34 to heat treat the material. After pre-peeling, the material is discharged from the discharge hopper 56 to the first conveyor belt 43. At the same time, the eccentric wheel 25 continues to rotate, causing the sliding sleeve 28 to reciprocate, thereby controlling the intermittent opening and closing of the flap valve 15 and the reciprocating swing of the steam nozzle 33.

[0067] In the third step, the steam-treated material enters the peeling roller 18, which performs pre-peeling. The sponge set 19 on its surface absorbs moisture from the material surface. When the peeling roller 18 rotates, the sponge set 19 contacts the scraper 37, scraping the moisture to the collection plate 39 and then discharging it through the water trough 38 and the water pipe 41.

[0068] The fourth step is that when in use, the staff can synchronously start the first conveyor support assembly 42 forward and the second conveyor support assembly 44 reverse, and start the electric push rod 52, so that the motors on the first conveyor support assembly 42 and the second conveyor support assembly 44 control the rotation of the first conveyor belt 43 and the second conveyor belt 45. At the same time, the start of the electric push rod 52 will cause its output shaft to push the first conveyor support assembly 42 to move longitudinally, so that the first conveyor support assembly 42 drives the limit block 47 and the rack 51 to slide in the limit groove 46 and the rectangular groove 48 respectively, so that the rack 51 on the first conveyor support assembly 42 engages with the gear 49 to rotate, and the gear 49 engages with the rack 51 on the second conveyor support assembly 44, so that the first conveyor support assembly 42 and the second conveyor support assembly 44 slide alternately, thereby driving the wear-resistant strips 54 on the first conveyor belt 43 and the second conveyor belt 45 to perform synchronous peeling processing on the materials in the longitudinal and transverse directions;

[0069] In the fifth step, when the limit block 47 of the first conveyor support assembly 42 slides to the end inside the limit groove 46 and hits the second limit switch 53, the output shaft of the electric push rod 52 will reset and retract, thereby driving the first conveyor support assembly 42 to retract, so that the rack 51 on the first conveyor support assembly 42 is engaged with the gear 49 in the opposite direction to the initial one, so that the first conveyor support assembly 42 and the second conveyor support assembly 44 perform reciprocating staggered sliding, so that not only can the material be peeled by relying on the reverse sliding of the first conveyor support assembly 42 and the second conveyor support assembly 44, but the reciprocating staggered sliding of the first conveyor belt 43 and the second conveyor belt 45 can further perform longitudinal peeling processing on the material, and the reciprocating longitudinal movement of the first conveyor belt 43 can make the hopper 56 evenly spread the material when discharging it onto the first conveyor belt 43, thereby improving the peeling efficiency.

9. A processing method of a healthy dietary raw material processing device, applied to the healthy dietary raw material processing device according to claim 8, characterized in that: The following steps are involved: S1: The staff connects the conveying pipe (34) to the external steam supply unit, and then puts the processed material into the feed hopper (14), and synchronously starts the two motors (17) for forward and reverse rotation respectively. The motor (17) drives the peeling roller (18) to rotate in the pretreatment box (13), and drives the eccentric wheel (25) to rotate. The eccentric wheel (25) rubs against the slider (27) through the slide groove (26). Under the constraint of the limit bar (24), the sliding sleeve (28) slides vertically along the limit bar (24). The sliding sleeve (28) pulls the valve control rod (21) through the first telescopic connecting rod (29), opens the flap valve (15), and allows the material to enter the steam treatment hopper (16); S2: When the sliding sleeve (28) moves upward, it will drive the L-shaped rod (35) to apply radial force to the steam nozzle (33) through the second telescopic connecting rod (36), so that the steam nozzle (33) rotates around the rotating shaft (32) in the storage groove (31). At the same time, the sliding sleeve (28) enters the special-shaped groove (22) and triggers the first stroke switch (23), opening the external steam valve. Steam is ejected from the steam nozzle (33) through the conveying pipe (34) to heat-treat the material. After pre-peeling, the material is discharged from the discharge hopper (56) to the first conveyor belt (43). At the same time, the eccentric wheel (25) continues to rotate to make the sliding sleeve (28) reciprocate, thereby controlling the intermittent opening and closing of the flap valve (15) and the reciprocating swing of the steam nozzle (33); S3: The steam-treated material enters the peeling roller (18), and the peeling roller (18) performs pre-peeling. The sponge set (19) on its surface absorbs the moisture on the surface of the material. When the peeling roller (18) rotates, the sponge set (19) contacts the scraper (37), scraping the moisture to the collection plate (39), and then discharged through the water trough (38) and the water pipe (41); S4: The staff starts the motors on the first conveyor support assembly (42) and the second conveyor support assembly (44) to rotate forward and reverse respectively, and turns on the electric push rod (52). At this time, the first conveyor belt (43) and the second conveyor belt (45) will rotate forward and reverse respectively. At the same time, the electric push rod (52) will push the first conveyor support assembly (42) to move longitudinally, so that the limit block (47) slides along the limit groove (46), and the rack (51) engages with the gear (49) in the rectangular groove (48), driving the two conveyor support assemblies to move in an interlaced manner. The wear-resistant strips (54) on the first conveyor belt (43) and the second conveyor belt (45) will synchronously peel the material longitudinally and transversely; S5: When the limit block (47) reaches the end of the limit slot (46) and triggers the second limit switch (53), the electric push rod (52) retracts, driving the first conveyor bracket assembly (42) to reset, and the rack (51) and the gear (49) engage in reverse, causing the two conveyor bracket assemblies to slide in reverse and staggered manner. This reciprocating motion completes the peeling.
