Description

Technical Field

[0001] The present invention relates to the technical field of peach lye treatment equipment, and in particular to a high-maturity peach lye treatment mechanism. Background Art

[0002] During the season when peaches (such as yellow peaches and honey peaches) are ripe, a large number of peaches are harvested in a short time, and processing them into canned peaches is an important processing route. When processing canned peach fruits, it is generally necessary to remove the outer skin of the peaches. For example, a yellow peach peeling system provided by a Chinese patent with the publication number CN209219188U can be used, which includes a first conveyor belt, a second conveyor belt, and a third conveyor belt arranged in sequence along the conveying direction; on the first conveyor belt, a feeding hopper and multiple groups of flattening rollers are arranged along its conveying direction, and there is a gap for yellow peaches to pass between the flattening rollers and the first conveyor belt. The flattening rollers are all driven by a driving motor arranged on one side of the first conveyor belt; on the third conveyor belt, three groups of spraying devices are arranged at intervals along its conveying direction. The utility model has a reasonable structural design and is convenient to use, can meet the peeling process in the production and processing of yellow peaches, avoids directly spraying caustic soda solution, and ensures the color and flavor of the yellow peaches after peeling. During actual operation, because the texture of high-maturity peaches is soft, such equipment cannot be used for peeling high-maturity peaches (a large amount of fragmentation may occur in the pulp after peeling). Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the present invention provides a high-maturity peach lye treatment mechanism, which solves the problem that the existing peeling equipment is not suitable for peeling high-maturity peaches.

[0004] According to an embodiment of the present invention, a high-maturity peach alkali liquid processing mechanism includes an upper shell and a lower shell located directly below the upper shell, the upper shell and the lower shell extend in a transverse direction and the upper and lower surfaces facing each other are open, a plurality of nozzle assemblies are arranged in the upper shell from one end to the other end, and a plurality of first brush rollers arranged to rotate are arranged in the lower shell from one end to the other end; it also includes a conveyor belt, the conveyor belt is an annular structure and has an upper conveying portion located between the upper shell and the lower shell and a lower conveying portion located below the lower shell, strip holes are arranged on the belt surface of the conveyor belt and bristles that can enter or exit the strip holes are arranged on the first brush roller; all nozzle assemblies are arranged equidistantly and a first rotatable pressure roller is provided between adjacent ones to move up and down. In the present scheme, peaches are transported by a conveyor belt similar to the prior art and are sprayed with alkali solution from the top. The difference is that in the present scheme, strip holes are provided on the conveyor belt and a first brush roller is provided below the upper conveying part. The peaches are sprayed with alkali solution during transportation and the bristles on the first brush roller below can brush the surface of the peaches. The skin will be brushed off while the alkali solution is sprayed, thereby achieving more efficient peeling and reducing the proportion of peach pulp breakage in the process, thereby solving the problem that the peeling equipment in the prior art is not suitable for peeling highly mature peaches.

[0005] Furthermore, the nozzle assembly includes a transverse tube, one end of which is fixedly passed through the upper shell and the other end is fixedly connected to the upper shell. A plurality of nozzles are also installed on the transverse tube along the length direction, and the nozzles have nozzles arranged downward.

[0006] Furthermore, a pair of mounting plates are fixedly connected to both sides of the bottom surface of the lower shell, and a plurality of second brush rollers are rotatably arranged between the two mounting plates and are arranged from one end of the lower shell to the other end. The lower conveying part passes over all the second brush rollers and the second brush rollers are provided with bristles that can enter or exit the strip holes.

[0007] Furthermore, a plurality of suction boxes located between the two mounting plates and above the lower conveying portion are fixedly mounted on the bottom of the lower shell body, the suction box is provided with a suction port located directly above the lower conveying portion, and the suction box is also connected to an inlet pipe fixedly passing through one of the mounting plates.

[0008] Furthermore, all the suction boxes are arranged toward one end of the lower shell.

[0009] Furthermore, a pair of second pressing rollers located at both ends of the lower shell body are rotatably arranged between the two mounting plates, the lower conveying portion passes under the two upper pressing rollers and all the second brush rollers are located between the two upper second pressing rollers.

[0010] Furthermore, the first pressure roller includes a roller and a rubber ring tube fixedly connected to the outside of the roller. The two ends of the roller are rotatably connected to the installation shaft, and the end of the installation shaft away from the roller is also fixedly connected to a connecting strip. The upper shell is provided with a sliding frame for each connecting strip to move up and down.

[0011] Further, a vertically arranged guide rod is fixedly connected inside the sliding box. A sliding hole is arranged on the connecting strip and is slidably sleeved outside the guide rod. A spring is also arranged around the guide rod and is located between the connecting strip and the top surface of the sliding hole.

[0012] Further, a number of convex strips protruding outward are fixedly connected to the outer wall of the coiling cylinder.

[0013] Further, adjacent first brush rollers are arranged close to each other.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] While the lye is being sprayed, the bristles on the first brush roller arranged below the upper conveying part can brush the surface of the peach. In this way, the skin will be brushed off while the lye is being sprayed, so the peeling is more efficient, and the fragmentation ratio of the peach pulp can be reduced during the process, solving the problem that the peeling equipment in the prior art is not suitable for peeling peaches with high maturity.

[0025] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0027] In an exemplary embodiment, as Figure 1-3As shown in the figure, this embodiment provides a high-maturity peach lye treatment mechanism, which includes an upper housing 1 and a lower housing 2 located directly below the upper housing 1. The upper housing 1 and the lower housing 2 extend in the transverse direction and the upper and lower surfaces facing each other are both open. A plurality of spray pipe assemblies are arranged in the upper housing 1 from one end to the other end. The spray pipe assemblies are used for spraying lye downward. A plurality of first brush rollers 3 arranged to rotate on their own are arranged in the lower housing 2 from one end to the other end. It also includes a conveyor belt 4. The conveyor belt 4 is of an annular structure and has an upper conveying part 5 located between the upper housing 1 and the lower housing 2 and a lower conveying part 6 located below the lower housing 2. Strip holes 7 are provided on the belt surface of the conveyor belt 4 and bristles capable of entering or exiting the strip holes 7 are provided on the first brush rollers 3. All the spray pipe assemblies are arranged at equal intervals and a rotatable first pressure roller 8 that can move up and down and telescopically is also provided between adjacent ones.In the present solution, the upper housing 1 and the lower housing 2 are relatively fixedly arranged. The upper conveying part 5 of the conveyor belt 4 passes through between the upper housing 1 and the lower housing 2, and the upper conveying part 5 is also close to the first brush roller 3 below, so that the bristles of the first brush roller 3 (the bristles have sufficient length to pass through to the upper part of the strip hole 7 after entering the strip hole 7) can pass through the strip hole 7 to the upper part of the upper conveying part 5. Similar to the prior art, the conveyor belt 4 is used to convey the peach 9. The difference is that in the present solution, it can be used to process the peach 9 with high maturity, that is, the peach 9 with high maturity is conveyed on the upper conveying part 5, and the first brush roller 3 below can brush the surface of the peach 9 while spraying the lye, so that the lye spraying also breaks the skin of the peach 9 and promotes the skin to fall off. Further, a first pressing roller 8 is also arranged on the upper housing 1 above the upper conveying part 5. The distance between the first pressing roller 8 and the upper conveying part 5 is slightly smaller than the height of the peach 9. At the same time, the first pressing roller 8 can move up and down. When the peach 9 passes through, the first pressing roller 8 first contacts the peach 9, and then gradually moves up and down as the peach 9 passes through. In this process, the peach 9 can contact the bristles of the first brush roller 3 below more fully, promoting the bristles to break the skin of the peach 9. More importantly, the first pressing rollers 8 are arranged at intervals, so that the peach 9 experiences multiple cycles of brushing - pressing and brushing during the conveying process. Combined with the lye spraying of the nozzle assembly, the peeling effect is better, and the fragmentation ratio of the pulp of the peach 9 can be reduced during the whole process, solving the problem that the peeling equipment in the prior art is not suitable for peeling the peach 9 with high maturity; more specifically, the interval distance between the first brush rollers 3 set in the present solution is small (it can also be without interval distance), so that the bristles passing through the upper conveying part 5 form an equidistant brushing section with a small interval above the upper conveying part 5, thereby brushing the peach 9 at intervals. At the same time, the peach 9 can also be turned over between multiple spaced brushing sections, so that the skin of each position of the peach 9 can be brushed; similar to the prior art, the running power of the conveyor belt 4 is provided by a separately provided driving component. For example, a driving roller and a driven roller are respectively arranged at both ends of the conveyor belt 4, and the driving motor drives the driving roller to rotate to drive the conveyor belt 4 to run, and the driven roller rotates synchronously. Different from the prior art, in the present solution, when the strip hole 7 on the conveyor belt 4 moves forward, it can pull the bristles on the first brush roller 3 passing through it, so that the first brush roller 3 can rotate by itself. In another solution, an additional external power can also be set to drive the first brush roller 3, and the driving method is similar to that adopted in the prior art. For example, the roller shaft of the first brush roller 3 extends outside the upper housing 1, and then sprockets are respectively fixed, and a chain cooperating with the sprockets is wound around, and the chain can be driven to run by a separately provided driving motor to drive.

[0028] In a further solution, such as Figure 1 、 2As shown in Figure 4, the nozzle assembly includes a transverse tube 10, one end of which is fixedly passed through the upper shell body 1, and the other end is fixedly connected to the upper shell body 1. A plurality of nozzles 11 are also installed on the transverse tube 10 along the length direction, and the nozzle 11 has a nozzle arranged downwardly. The end of the transverse tube 10 located outside the upper shell body 1 is used to connect the alkali solution. After the alkali solution enters the transverse tube 10, it is sprayed downwardly from the nozzle of the nozzle 11, thereby realizing the alkali solution spraying on the peaches 9. In more detail, a drain pipe 12 connected to the bottom of the lower shell body 2 is also fixedly connected thereto, and the drain pipe 12 is used for draining the downstream alkali solution waste liquid. More specifically, during the spraying process, the alkali solution can also flush and carry the generated skin scraps downward, and the alkali solution waste liquid will also carry the skin scraps, so the drain pipe can be set larger to prevent blockage.

[0029] In a further scheme, as shown in 1, 2, 5 and 6, the first pressure roller 8 includes a roller 13 and a rubber ring tube 14 fixedly connected to the outside of the roller 13, and the two ends of the roller 13 are rotatably connected with a mounting shaft 15, and the end of the mounting shaft 15 away from the roller 13 is also fixedly connected with a connecting strip 16, and the upper shell 1 is provided with a sliding frame 17 for each connecting strip 16 to move up and down. That is, the outer layer of the first pressure roller 8 is made of rubber material (the rubber ring tube 14 is made of rubber material), and the contact between the roller 13 and the peach 9 can avoid excessive squeezing of the peach 9. In the process of contacting the peach 9, the roller 13 can rotate around the mounting shaft 15, and the connecting strip 16 can be adaptively moved up and down. In more detail, a vertically arranged guide rod 18 is fixedly connected to the sliding frame 17, and a sliding hole that is slidably sleeved outside the guide rod 18 is provided on the connecting strip 16. A spring 19 is also arranged around the guide rod 18 and is located between the connecting strip 16 and the top surface of the sliding hole. The connecting strip 16 is a long square strip structure (with a square cross section), and the guide The rod 18 provides guidance in the vertical direction to prevent lateral displacement, and the spring 19 provides a certain pressure so that the rubber ring tube 14 can appropriately press down the peach 9 to ensure that the surface of the peach 9 can fully contact the bristles of the first brush roller 3; in a further detailed scheme, a plurality of convex strips 20 are fixedly connected to the outer wall of the winding tube, and the convex strips 20 are also made of rubber and can be extended along the axial direction of the roller 13. During the movement of the peach 9, the plurality of convex strips 20 can flip the peach 9, so that the peach 9 rolls after passing through (i.e., the corresponding position below the first pressure roller 8), thereby avoiding some positions from failing to contact the first brush roller 3 normally.

[0030] like Figure 1 , 2As shown in FIGS. 6 and 7, in a further embodiment, a pair of mounting plates 21 are fixedly connected to both sides of the bottom surface of the lower housing 2. Between the two mounting plates 21, a plurality of second brush rollers 22 arranged from one end to the other end of the lower housing 2 are rotatably provided (the rotation mode of the second brush rollers 22 is similar to that of the first brush roller 3, and it can be driven by the operation of the conveyor belt 4 or an external drive can be added, such as the aforementioned chain, sprocket, and drive motor). The lower conveying portion 6 passes above all the second brush rollers 22, and bristles capable of entering or exiting the strip holes 7 are provided on the second brush rollers 22 (the bristles of the second brush rollers 22 can be shorter than those of the first brush roller 3 and do not need to pass through the strip holes 7. During the process of entering and exiting the strip holes 7, the remaining shredded skins can be brushed downward out of the strip holes 7). The peaches 9 are conveyed to the next process, such as the cleaning process, through the upper conveying portion 5. The lower conveying portion 6 then turns back and passes between the two mounting plates 21. The second brush rollers 22 provided below the lower conveying portion 6 can brush the strip holes 7, thereby cleaning the remaining shredded skins. More specifically, the bristles of the second brush rollers 22 can be made of steel bristles to better provide a brushing effect, while the first brush roller 3 is preferably made of plastic fiber bristles, such as nylon bristles, to provide a relatively gentle brushing and avoid excessive damage to the shallow pulp of the peaches 9. In a further embodiment, a plurality of suction boxes 23 are fixedly installed at the bottom of the lower housing 2 between the two mounting plates 21 and above the lower conveying portion 6. The suction boxes 23 are provided with suction inlets 24 directly above the lower conveying portion 6, and the suction boxes 23 are also connected to an inlet pipe 25 fixedly passing through one of the mounting plates 21. The inlet pipe 25 is used to connect to an external suction device to generate negative pressure in the suction boxes 23. The distance between the provided suction inlets 24 and the lower conveying portion 6 below is relatively small, so that some shredded skins that reach above the upper conveying portion 5 due to brushing can be sucked into the suction boxes 23 and then be sucked out to the outside, making the cleaning effect better. More specifically, all the provided suction boxes 23 are located at one end of the lower housing 2 (near the end where the lower conveying portion 6 turns upward). That is, first, the lower conveying portion 6 is brushed and cleaned by the second brush rollers 22. After a certain distance, most of the shredded skins fall off, and then the remaining second brush rollers 22 and suction boxes 23 are used to more thoroughly clean the remaining shredded skins.

[0031] As Figure 1 , 2 shown, a pair of second pressure rollers 26 are rotatably provided at both ends of the lower housing 2 between the two mounting plates 21. The lower conveying portion 6 passes below the two upper pressure rollers, and all the second brush rollers 22 are located between the two upper second pressure rollers 26. The second pressure rollers 26 provide a limit to the lower conveying portion 6 from above to prevent a large upward displacement during the brushing process, so as to enable the second brush rollers 22 to perform brushing and cleaning more efficiently.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
