Description

Technical Field

[0001] This invention relates to the field of egg conveying equipment technology, specifically to a flexible roller conveyor for clean and non-damaging egg conveying that prevents collisions. Background Technology

[0002] In egg processing plants, cleaning is an essential step. Before cleaning, eggs need to be transported. Referring to the egg processing conveyor belt structure disclosed in patent publication number CN219258530U, a tumbling device is used. A rotating rod drives multiple connecting plates and brushes to rotate. When the eggs in the groove pass the bottom of the rotating rod, the brushes can rub against the outer side of the bottom eggs. The brushes can not only increase the friction with the egg surface, but also ensure that the eggs can roll in the groove.

[0003] However, in the "water bath soaking - one-by-one conveying - high pressure spraying" process in egg processing plants, there are common problems such as excessive impact leading to the expansion of microcracks, and unstable positioning in wet and slippery conditions causing the eggs to move and collide during high pressure spraying. It is difficult to achieve a flexible dynamic balance between "allowing the eggs to rotate with the rollers" and "providing sufficient cleaning pressure". Therefore, this invention proposes a solution. Summary of the Invention

[0004] The technical problem to be solved by this invention is how to avoid the problem of eggs moving and colliding when subjected to excessive water flow. The purpose is to set up a flexible roller conveyor for cleaning eggs without damage, so as to solve the above-mentioned technical problem.

[0005] The present invention provides the following device: a collision-resistant flexible roller conveyor for cleaning eggs without damage, comprising a water bath and a conveyor roller conveyor horizontally connected to the water bath, wherein a hydraulic suspension support component is provided in the middle of the water bath and an elastic conveying component is provided inside the conveyor roller conveyor.

[0006] The hydraulic suspension support assembly includes a suspension plate suspended in the middle of a water bath tank. The bottom of the suspension plate is connected to an air inlet pipe connected to a high-pressure air pump. The suspension plate is provided with a blow hole and a blow groove connected to the air inlet pipe.

[0007] The flexible conveying assembly includes conveyor rollers continuously arranged in a conveyor roller track, the conveyor rollers being fitted with arc-shaped airbags and flat bags, wherein the flat bags are in rolling contact with the eggs being conveyed.

[0008] Furthermore, the water bath has an integrally formed soaking tank inside, with a central hole for installing the suspension plate in the middle of the soaking tank, and through holes evenly distributed on the soaking tank. The soaking tank has a conical structure and forms a water storage cavity with the water bath.

[0009] Furthermore, the suspension plate has a side connecting hole at the connection between the spray hole and the spray groove, and a non-through central hole is provided in the middle of the suspension plate, and a transverse connecting hole is provided between the spray groove and the central hole.

[0010] Furthermore, the suspension plate is not horizontally positioned and faces one side of the conveyor roller conveyor, and the suspension plate matches the central hole.

[0011] Furthermore, a cleaning cover is installed on the upper end of the conveyor roller away from the water bath. Impact tubes are arranged in an array on the cleaning cover, and the impact tubes extend into the cleaning cover and are equipped with supporting arc plates.

[0012] Furthermore, the supporting arc plate is positioned directly above the gap between the pair of conveying rollers, and the arc-shaped concave surface of the supporting arc plate together with the conveying gap between the pair of conveying rollers constitutes the conveying area of ​​the egg.

[0013] Furthermore, a top support plate is installed on the lower surface of the cleaning cover corresponding to the supporting arc plate. The impact pipe passes through the top support plate and is connected to the supporting arc plate. An elastic column connected to the supporting arc plate is installed on the lower side of the top support plate.

[0014] Furthermore, the elastic conveying assembly is provided with a compression conveying state and a suspension conveying state. In the compression conveying state, the arc-shaped airbag is filled with a first air pressure, and the flat bag rolls in contact with the egg surface with a first contact pressure, and provides a tangential driving force for conveying. In the suspension conveying state, the arc-shaped airbag is filled with a second air pressure, and the flat bag rolls in contact with the egg surface with a second contact pressure, and provides a tangential driving force for guiding.

[0015] Furthermore, the first air pressure is greater than the second air pressure, and when the arc-shaped airbag is inflated with the first air pressure, the flat bag makes elastic, compressed, and rolling contact with the egg surface; when the arc-shaped airbag is inflated with the second air pressure, the flat bag makes light, rolling contact with the egg surface.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] 1. This invention uses a hydraulic suspension support component in a water bath to completely detach the egg from rigid contact in the hydraulic suspension area. The egg then relies on the air-water mixing flow field to achieve non-contact suspension and directional drift. The non-contact suspension stage eliminates the risk of crack propagation caused by collisions or local turbulent impacts during the water bath immersion stage. The directional drift stage ensures the accuracy of the pushing direction, thus solving the problems of unstable positioning and impacts during the transition section in a slippery state.

[0018] 2. Furthermore, by using the elastic conveying components set up during the transmission process, the input of the first air pressure and the second air pressure respectively constitute the squeezing conveying state and the suspension conveying state, ensuring that the eggs can be sufficiently constrained during the washing process, so as to prevent cracking caused by high pressure surge and impact, and realize the damage-free conveying of clean eggs.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided in conjunction with embodiments and appendices. Figure 1-8 As shown, the present invention will be further described in detail. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example 1: The present invention proposes a collision-resistant flexible roller conveyor for cleaning eggs without damage, including a water bath 1 and a conveyor roller 2 horizontally connected to the water bath 1. A hydraulic suspension support component is provided in the middle of the water bath 1, and an elastic conveying component is provided inside the conveyor roller 2.

[0031] The hydraulic suspension support assembly includes a suspension plate 6 suspended in the middle of the water bath tank 1. The bottom of the suspension plate 6 is connected to an air inlet pipe 11 connected to a high-pressure air pump. The suspension plate 6 is provided with a blow hole 7 and a blow groove 8 connected to the air inlet pipe 11.

[0032] The flexible conveying assembly includes conveying rollers 5 continuously arranged in the conveying roller conveyor 2, and the conveying rollers 5 are fitted with arc-shaped airbags 15 and flat bags 16, wherein the flat bags 16 are in rolling contact with the eggs being conveyed.

[0033] The water bath 1 has an integrally formed soaking tank 3. The soaking tank 3 has a central hole for installing the suspension plate 6, and the soaking tank 3 has evenly distributed through holes 4. The soaking tank 3 has a conical structure and forms a water storage cavity 10 with the water bath 1. The water bath 1 is filled with clean water through the water storage cavity 10, and the liquid level is set at the top of the conical structure of the soaking tank 3. Thus, the eggs can be fully soaked in the soaking tank 3.

[0034] The suspension plate 6 has a side connecting hole 12 at the connection between the spray hole 7 and the spray groove 8, and a non-through central hole 14 is provided in the middle of the suspension plate 6. A transverse connecting hole 13 is provided between the spray groove 8 and the central hole 14. The suspension plate 6 is not horizontally set and faces one side of the conveyor roller 2. The suspension plate 6 matches the central hole.

[0035] The flexible conveying component is equipped with both compression conveying mode and suspension conveying mode.

[0036] In the extrusion conveying state: the arc-shaped airbag 15 is filled with the first air pressure, the flat bag 16 makes light rolling contact with the surface of the egg, and provides tangential driving force for conveying; that is, the egg is subjected to extrusion conveying when it is transported in the conveying roller 2.

[0037] In the suspended transport state: the arc-shaped airbag 15 is filled with a second air pressure, the flat bag 16 rolls in contact with the egg surface with a second contact pressure, and provides a tangential driving force for guidance;

[0038] The first air pressure is greater than the second air pressure. When the arc-shaped air bladder 15 is filled with the first air pressure, the flat bag 16 is in elastic, compressed, and rolling contact with the egg surface. When the arc-shaped air bladder 15 is filled with the second air pressure, the flat bag 16 is in light, rolling contact with the egg surface.

[0039] The movement process and principle of the elastic conveying component are as follows: In the extrusion conveying state, the external air source fills the arc-shaped airbag 15 with high-pressure gas of the first pressure. The arc-shaped airbag 15 expands and extrudes the flat bag 16, causing the flat bag 16 to bulge further in the radial direction, increasing the contact area and rolling friction with the egg surface. At this time, the conveying roller 5 applies tangential driving force to the egg through the flat bag 16 to achieve "extrusion" conveying.

[0040] In the suspended transport state, the arc-shaped airbag 15 is filled with high-pressure gas of the second pressure. The arc-shaped airbag 15 expands and lightly touches the flat bag 16, so that the egg and the flat bag 16 make slight contact, providing rolling guidance and tangential driving force, and driving the egg to achieve "suspended" transport.

[0041] It should be noted that the first air pressure is greater than the second air pressure. In terms of the contact method, when the arc-shaped airbag 15 bears the first air pressure, the flat bag 16 makes elastic, pressing, rolling contact with the egg surface. When the arc-shaped airbag 15 bears the second air pressure, the flat bag 16 makes light, rolling contact with the egg surface.

[0042] The basic process and principle of this embodiment: The eggs to be cleaned are first placed in the soaking tank 3 of the water bath 1 to complete the water bath soaking, so as to ensure that the dirt attached to the surface is softened in advance before cleaning.

[0043] During this process, before the high-pressure gas is introduced, all the eggs are gathered above the suspension plate 6. After the high-pressure air pump supplies compressed air into the suspension plate 6 through the air inlet pipe 11, the gas is ejected at high speed through the blow hole 7 and the blow groove 8 and enters the water in the water bath 1, forming a dense and stable gas-water mixed upward flow field on the upper surface of the suspension plate 6.

[0044] The air-water mixed upward flow field generates a vertical lifting force on the egg that is sufficient to overcome its own weight, causing the egg to detach from the contact of the rigid component and be in a state of hydraulic suspension. At the same time, since the suspension plate 6 is not horizontally set and is inclined to the side of the conveyor roller 2, the air-water mixed upward flow field provides not only a vertical lifting force, but also a horizontal component force pointing towards the inlet of the conveyor roller 2, which pushes the egg to slowly drift into the conveyor roller 2 without contact.

[0045] When the egg is propelled by the air-water mixture flow field to the edge of the suspension plate 6 and is about to leave the projection area of ​​the suspension plate 6, the hydraulic support disappears, and the egg is no longer effectively supported by the air-water mixture field. Then, under its own gravity, it naturally falls into the gap between two adjacent conveying rollers 5 in the conveyor roller 2.

[0046] It should be further explained that the airflow distribution of the air-water mixed rising flow field is as follows: the side connecting hole 12 allows the airflow of the spray hole 7 and the spray channel 8 to communicate with each other, avoiding sudden pressure changes; the transverse connecting hole 13 connects the spray channel 8 with the central hole 14. The central hole 14, as a pressure stabilizing cavity with a non-penetrating structure, can effectively suppress airflow pulses and ensure that the air-water spray pressure in each area of ​​the upper surface of the suspension plate 6 is uniform, continuous and stable; the through hole 4 allows the water between the soaking tank 3 and the water storage chamber 10 to freely exchange, maintain liquid level balance and facilitate the sedimentation of impurities.

[0047] Example 2: A cleaning cover plate 9 is installed on the upper end of the side of the conveyor roller 2 away from the water bath box 1. Impact tubes 18 are arranged in an array on the cleaning cover plate 9. The impact tubes 18 extend into the cleaning cover plate 9 and a supporting arc plate 20 is installed thereon.

[0048] The supporting arc plate 20 is positioned directly above the gap between the pair of conveying rollers 5, and the arc-shaped concave surface of the supporting arc plate 20 and the conveying gap between the pair of conveying rollers 5 together constitute the conveying area of ​​the egg.

[0049] A top support plate 17 is installed on the lower surface of the cleaning cover plate 9 corresponding to the supporting arc plate 20. The impact pipe 18 passes through the top support plate 17 and is connected to the supporting arc plate 20. An elastic column 19 connected to the supporting arc plate 20 is installed on the lower side of the top support plate 17.

[0050] When the eggs are conveyed by the conveyor roller 5 to the side of the conveyor roller 2 away from the water bath 1, they enter the high-pressure spraying area below the cleaning cover plate 9. The lower part of the eggs is elastically supported and driven by the flat bag 16 on the conveyor roller 5, while the upper part is limited by the arc concave surface of the supporting arc plate 20.

[0051] During the spray cleaning process, the impact pipe 18 introduces high-pressure cleaning water to thoroughly rinse the surface of the egg from the top up. The eggs are continuously turned over during transport, ensuring a complete cleaning. At the same time, the top support plate 17 provides rigid support for the supporting arc plate 20. The elastic column 19 connects the top support plate 17 and the supporting arc plate 20. When the supporting arc plate 20 is subjected to the back pressure of the high-pressure water flow or when the egg is squeezed upwards, the elastic column 19 undergoes compression deformation, absorbing the impact energy. This gives the supporting arc plate 20 a vertical floating buffering capacity, further preventing the egg from being crushed due to excessive restraint or from jumping out due to insufficient restraint during the high-pressure spray cleaning process.

[0052] Example 3: This example combines the technical content of Example 1 and Example 2 to form the following usage method:

[0053] Step 1: The eggs to be cleaned are first placed in the soaking tank 3 of the water bath 1 to complete the water bath soaking, so as to ensure that the dirt attached to the surface is softened in advance before cleaning;

[0054] Step 2: After the high-pressure air pump supplies compressed air into the suspension plate 6 through the air inlet pipe 11, the gas is sprayed out at high speed through the spray hole 7 and spray groove 8, which "pneumatically lifts" the eggs gathered at the suspension plate 6, and at the same time, pushes the eggs to drift slowly into the conveyor roller 2 without contact.

[0055] Step 3: The eggs entering the conveyor roller 2 are initially in a suspended conveying state, that is, the arc-shaped airbag 15 is filled with the second air pressure, which causes the flat bag 16 to make light rolling contact with the eggs. When the eggs enter the high-pressure cleaning area, the arc-shaped airbag 15 is filled with the first air pressure, which causes the flat bag 16 to make elastic pressing rolling contact with the eggs, thus achieving squeezing and conveying.

[0056] Step 4: After cleaning, collect the eggs in sequence.

[0057] In summary, this invention enables the egg to be completely detached from rigid contact in the hydraulic suspension area by setting a hydraulic suspension support component in the water bath 1. It achieves non-contact suspension and directional drift by relying on the air-water mixed flow field. The non-contact suspension stage eliminates the risk of crack propagation caused by collisions or local turbulent impacts during the water bath immersion stage. The directional drift stage ensures the accuracy of the pushing direction, thus solving the problems of unstable positioning and impacts during the transition section in a wet and slippery state.

[0058] On the other hand, by using the elastic conveying components set up during the transmission process, the input of the first air pressure and the second air pressure respectively constitute the squeezing conveying state and the suspension conveying state, ensuring that the eggs can be sufficiently constrained during the washing process, so as to prevent cracking caused by high pressure surge and impact, and realize the damage-free conveying of clean eggs.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
