Vegetable pre-packaged food drying apparatus with turnover mechanism

Abstract

This invention relates to the field of food drying technology, specifically to a vegetable pre-packaged food drying equipment with a flipping mechanism. It includes a base, a chain conveyor belt on top of the base, and side guards on both sides of the base away from the chain conveyor belt. Several raised mounting brackets are installed on top of the side guards. A pressure-bearing inclined plane slides relative to a driving inclined plane, causing a horizontal force to push the pressure-bearing base horizontally. During this time, the distance between the driving push plate and the limiting baffle shortens, and the spring is compressed to store elastic potential energy. The driving push plate then drives the shovel-shaped inclined plate downwards via a second guide rod. When the vegetable package slides upwards along the upper surface of the shovel-shaped inclined plate, the piston rod of the hydraulic rod retracts into the cylinder, and the driving push plate resets under the restoring force of the spring. Thus, the driving push plate applies a pushing force towards the upstream side of the chain conveyor belt to the vegetable package, ensuring that the vegetable package can be flipped 180°.

Description

Technical Field

[0001] This invention relates to the field of food drying technology, and more specifically, to a drying device for pre-packaged vegetables with a flipping mechanism. Background Technology

[0002] In the industrial processing of pre-packaged vegetables, after washing, sterilization, and sealing, a large amount of residual water stains remain on the surface of the packaging bags. If these are not thoroughly dried, they will directly affect subsequent processes such as coding, labeling, and packing. Furthermore, they can easily lead to mold growth, watermark fading, and label peeling, significantly reducing the appearance and shelf life of the finished pre-packaged vegetables. Therefore, drying the bag surface is an indispensable and crucial step in the vegetable pre-packaged processing line. Currently, the industry commonly uses conveyor belts paired with fixed blowers to air-dry the surface of bagged vegetables during transport. This type of equipment has a simple structure, low operating costs, and can meet the basic drying needs of large-scale continuous production, making it widely used in various fruit and vegetable pre-packaged food processing production lines.

[0003] Existing traditional vegetable pre-packaging drying equipment still has the following technical shortcomings in actual production applications: First, the fans in traditional air-drying equipment are mostly fixed unidirectional blowing structures, which can only dry the upward-facing side of the vegetable package. The bottom of the vegetable package is tightly adhered to the conveyor belt surface, forming a complete drying dead zone, where residual water cannot be effectively dried, resulting in extremely poor drying uniformity. Second, existing equipment lacks a dedicated automated flipping structure, making it impossible to flip and adjust the vegetable packages during transport. Relying solely on manual flipping is not only inefficient and labor-intensive but also prone to damaging the packaging bags and contaminating the materials, failing to meet the requirements of continuous production line operations. Third, the flipping angle and force of conventional flipping auxiliary structures are uncontrollable. After flipping, the vegetable packages easily stick to the conveyor structure and reposition themselves, failing to completely expose the water-covered bottom surface. Furthermore, adjacent vegetable packages tend to stack and stick together, leading to localized water residue.

[0004] In view of this, we propose a vegetable pre-packaged food drying device with a flipping mechanism to improve the shortcomings of the prior art. Summary of the Invention

[0005] This invention provides a vegetable pre-packaged food drying equipment with a flipping mechanism, which solves the problems of existing fixed air drying equipment that can only dry the upper surface of vegetable bags, leaving the bottom as a drying dead corner, lacking an automatic flipping mechanism that can stably coordinate with the production line, and the simple flipping structure that cannot fully flip the vegetable bags. After flipping, the packaging bags are easily stuck to the conveyor surface and the materials are piled up, making it difficult to completely remove residual water stains from the bottom of the bags. Manual flipping is inefficient and easily damages the packaging bags and contaminates the products.

[0006] To achieve the above objectives, the vegetable pre-packaged food drying equipment with a flipping mechanism includes a base, a chain conveyor belt on the top of the base, side guards on the two sides of the top of the base that are far apart from the chain conveyor belt, and several raised mounting frames installed on the top of the side guards. The upper surface of the chain conveyor belt is provided with a blocking and pushing component, each of the side blocks is provided with multiple air drying components, and each of the raised mounting frames is provided with a flipping component below it. The downstream side of the blocking and pushing component is used to push the vegetable bag to move, the air-drying component is used to dry the vegetable bag on top of the blocking and pushing component, the flipping component is used to scoop up the downstream end of the vegetable bag, and the air-drying component can push the vegetable bag away from the upstream side of the blocking and pushing component so that the downstream end of the vegetable bag can be scooped up by the next flipping component.

[0007] In the above technical solution, the packaged vegetable bags are placed on top of the chain conveyor belt, and the blocking and pushing components move the vegetable bags downstream. During this period, multiple drying components dry the residual moisture on the top of the passing vegetable bags to facilitate subsequent transportation and processing.

[0008] Because the bottom of the vegetable bag is in contact with the top of the chain conveyor belt, the water attached to the bottom of the vegetable bag cannot be directly dried by the air-drying component. When the vegetable bag passes under the flipping component, the flipping component scoops it up from the downstream end of the vegetable bag and flips it 180°, so that the side of the vegetable bag that originally had water on it is facing upwards, ensuring that the air-drying component can dry this residual moisture. The flipping component can push the vegetable bag to the upstream side of the blocking pushing component, and the vegetable bag is pushed away from the blocking pushing component by the flipping component a certain distance, ensuring that the vegetable bag can be flipped up by the next flipping component.

[0009] Based on this, the blocking and pushing assembly includes a push plate fixedly connected to the top of the chain conveyor belt, and a feeding roller for driving the vegetable bag away from itself is provided above the push plate.

[0010] Furthermore, a pair of limiting bolts are provided on the top of the push plate along the length direction, and the two limiting bolts are fixedly connected to the two ends of the push plate that are far apart from each other. The feeding roller is rotatably connected between the two limiting bolts.

[0011] With this design, after the vegetable bag is flipped over, the previously dried top becomes the bottom, and the bottom falls to contact the top of the feeding roller. Since the feeding roller can slide freely between the two limit bolts, the flipped vegetable bag rolls down along the outer surface of the feeding roller, so that after the vegetable bag rolls down from the top of the feeding roller, there is a gap between it and the upstream side of the push plate, so that it can be flipped another 180° later.

[0012] In another technical solution, the drying assembly includes a mounting groove formed on the side panel, and the mounting groove is provided with a fan for blowing air onto the top of the vegetable bag.

[0013] Furthermore, a mounting frame is fixedly installed in the mounting slot, and the fan is rotatably connected to the side of the mounting frame facing the chain conveyor belt. A drive motor for driving the fan is provided on the side of the mounting frame away from the chain conveyor belt. The drive motor includes a body and an output shaft. The body is fixedly connected to the mounting frame, and the output shaft is coaxially connected to the fan.

[0014] This technical solution involves placing the vegetable package on top of the chain conveyor belt, then connecting the power supply to the drive motor to make the output shaft drive the fan to rotate, continuously blowing air between the two side baffles to dry the moisture on the top side of the vegetable package being transported on the chain conveyor belt, so as to facilitate subsequent processing of the vegetable package.

[0015] In addition, the flipping assembly includes a shovel ramp disposed below the lifting mounting frame. The bottom of the shovel ramp is inclined upstream of the chain conveyor belt, and the shovel ramp slides relative to the lifting mounting frame in the vertical direction to shovel up the upstream end of the vegetable bag.

[0016] Furthermore, a limit baffle is fixedly connected to the top of the shovel-moving inclined plate, and a first guide rod is fixedly connected to the top of the shovel-moving inclined plate on both sides away from the limit baffle. The first guide rod is slidably connected to the raised mounting frame.

[0017] A number of second guide rods are fixedly connected to the side of the drive push plate away from the shovel inclined plate. The end of the second guide rod away from the drive push plate is slidably connected to the limiting baffle. A spring is sleeved on the outer side of the second guide rod between the drive push plate and the limiting baffle.

[0018] Preferably, a drive block is provided above the shovel inclined plate, and a hydraulic rod for driving its own lifting and lowering is provided on the top of the drive block. The hydraulic rod includes a cylinder and a piston rod. The cylinder is fixedly connected to the lifting mounting frame, and the piston rod is fixedly connected to the top of the drive block. Several third guide rods are fixedly connected to the top of the drive block, and the end of the third guide rod away from the drive block is slidably connected to the lifting mounting frame.

[0019] The top of the drive push plate is fixedly connected to a pressure bearing seat, the top of the pressure bearing seat is provided with a pressure bearing slope, the bottom of the drive block is provided with a drive slope, and the pressure bearing slope and the drive slope are slidably fitted together.

[0020] As can be seen from the above scheme, when the vegetable bag is pushed forward by the push plate at the top of the chain conveyor belt, the shovel plate moves downward and shovels up the bottom of the downstream end of the vegetable bag through its bottom. Then, the downstream end of the vegetable bag is driven upward by the upward-moving shovel plate, while the upstream end of the vegetable bag is still pushed by the push plate. Thus, the vegetable bag at the top of the chain conveyor belt is rotated 180° under the combined action of the push plate and the shovel plate, thereby drying the side of the vegetable bag with moisture.

[0021] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: When the vegetable bag moves below the shovel inclined plate, the piston rod of the hydraulic rod extends from the cylinder, driving the drive block to move downward. The pressure-bearing inclined plate slides relative to the drive inclined plate. At this time, the horizontal component force pushes the pressure seat to move in the horizontal direction. At this time, the distance between the drive push plate and the limit baffle shortens. During this period, the spring is compressed and stores elastic potential energy. At the same time, the vertical component force drives the push plate to move downward. The drive push plate then drives the shovel inclined plate to slide downward through the second guide rod. When the vegetable bag slides upward along the upper surface of the shovel inclined plate, the piston rod of the hydraulic rod retracts into the cylinder. The drive push plate is then reset under the action of the spring restoring force. Thus, the drive push plate applies a pushing force towards the upstream side of the chain conveyor belt to the vegetable bag, ensuring that the vegetable bag can be rotated 180°.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Traditional air-drying equipment typically uses fixed, unidirectional blowers that can only dry the top side of the vegetable bags. The bottom of the bags remains tightly pressed against the conveyor belt, creating a complete drying dead zone where residual water cannot be effectively dried, resulting in extremely uneven drying. Secondly, existing equipment lacks a dedicated automated turning mechanism, making it impossible to turn the vegetable bags over during transport. Relying solely on manual turning is inefficient, labor-intensive, and prone to damaging packaging and contaminating materials, failing to meet the demands of continuous production lines. Thirdly, the turning angle and force of conventional turning auxiliary structures are uncontrollable. After turning, the vegetable bags easily stick to the conveyor structure, failing to completely expose the water-soaked bottom. Furthermore, adjacent vegetable bags tend to stack and stick together, leading to localized water accumulation.

[0028] Please see Figure 1 - Figure 3 To solve the above problems, the present invention aims to provide a vegetable pre-packaged food drying equipment with a flipping mechanism. The food drying equipment includes a base 100, a chain conveyor belt 120 on the top of the base 100, side guards 110 on the two sides of the top of the base 100 that are far apart from the chain conveyor belt 120, and a plurality of raised mounting frames 130 installed on the top of the side guards 110. The upper surface of the chain conveyor belt 120 is provided with a blocking and pushing component 200, each side baffle 110 is provided with multiple drying components 300, and each raised mounting frame 130 is provided with a flipping component 400. The downstream side of the blocking and pushing component 200 is used to push the vegetable bag to move, the drying component 300 is used to dry the vegetable bag on top of the blocking and pushing component 200, the flipping component 400 is used to scoop up the downstream end of the vegetable bag, and the drying component 300 can push the vegetable bag away from the upstream side of the blocking and pushing component 200 so that the downstream end of the vegetable bag can be scooped up by the next flipping component 400.

[0029] During implementation, the packaged vegetable bags are placed on top of the chain conveyor belt 120, and the blocking and pushing component 200 pushes the vegetable bags downstream. During this time, multiple drying components 300 dry the residual moisture on the top of the passing vegetable bags to facilitate subsequent transportation and processing.

[0030] Since the bottom of the vegetable bag is in contact with the top of the chain conveyor belt 120, the water attached to the bottom of the vegetable bag cannot be directly dried by the drying component 300. When the vegetable bag passes under the flipping component 400, the flipping component 400 scoops it up from the downstream end of the vegetable bag and flips it 180°, so that the side of the vegetable bag that originally had water on it is facing upwards, ensuring that the drying component 300 can dry the residual moisture. The flipping component 400 can push the vegetable bag to the upstream side of the blocking pushing component 200, and the vegetable bag is pushed away from the blocking pushing component 200 by the flipping component 400 a distance, ensuring that the vegetable bag can be flipped up by the next flipping component 400.

[0031] Next, as Figure 4 As shown, the specific structure of the blocking and pushing assembly 200 and how to move the turned vegetable bag away from the upstream side of the blocking and pushing assembly 200 are disclosed. The blocking and pushing assembly 200 includes a push plate 210 fixedly connected to the top of the chain conveyor belt 120, and a feeding roller 230 for driving the vegetable bag away from itself is provided above the push plate 210.

[0032] Furthermore, a pair of limit bolts 220 are provided on the top of the push plate 210 along the length direction. The two limit bolts 220 are fixedly connected to the two ends of the push plate 210 that are far apart. The feeding roller 230 is rotatably connected between the two limit bolts 220.

[0033] It should be noted that after the vegetable package is flipped, the previously dried top becomes the bottom, and the bottom falls and contacts the top of the feeding roller 230. Since the feeding roller 230 can slide freely between the two limit bolts 220, the flipped vegetable package rolls down along the outer surface of the feeding roller 230, so that after the vegetable package rolls down from the top of the feeding roller 230, there is a gap between it and the upstream side of the push plate 210, so that it can be flipped another 180° later.

[0034] exist Figure 5 The principle of the air-drying component 300 drying the surface moisture of the vegetable bag is disclosed. The air-drying component 300 includes a mounting groove opened on the side panel 110, and a fan 320 for blowing air to the top of the vegetable bag is provided in the mounting groove.

[0035] Furthermore, a mounting frame 310 is fixedly installed in the mounting slot. The fan 320 is rotatably connected to the side of the mounting frame 310 facing the chain conveyor belt 120. A drive motor 330 for driving the fan 320 is provided on the side of the mounting frame 310 away from the chain conveyor belt 120. The drive motor 330 includes a body and an output shaft. The body is fixedly connected to the mounting frame 310, and the output shaft is coaxially connected to the fan 320.

[0036] In other words, after placing the vegetable bag on top of the chain conveyor belt 120, the power supply of the drive motor 330 is turned on, causing the output shaft to drive the fan 320 to rotate, continuously blowing air between the two side baffles 110 to dry the moisture on the upper side of the vegetable bag transported on top of the chain conveyor belt 120, so as to facilitate the subsequent processing of the vegetable bag.

[0037] Based on the above explanation, the following will be conducted... Figure 6 - Figure 8 To explain the preferred effect of the flipping assembly 400, the flipping assembly 400 includes a scooping ramp 410 disposed below the lifting mounting frame 130. The bottom of the scooping ramp 410 is inclined upstream of the chain conveyor belt 120, and the scooping ramp 410 slides relative to the lifting mounting frame 130 in the vertical direction to scoop up the upstream end of the vegetable bag.

[0038] Furthermore, a limit baffle 412 is fixedly connected to the top of the shovel inclined plate 410, and a first guide rod 411 is fixedly connected to the top of the shovel inclined plate 410 on both sides away from the limit baffle 412. The first guide rod 411 is slidably connected to the cantilever mounting frame 130.

[0039] When the vegetable bag is pushed forward by the push plate 210 at the top of the chain conveyor belt 120, the shovel sloping plate 410 moves downward and shovels up the bottom of the downstream end of the vegetable bag through its bottom. Then the downstream end of the vegetable bag is driven upward by the upward-moving shovel sloping plate 410, while the upstream end of the vegetable bag is still pushed by the push plate 210. Thus, the vegetable bag at the top of the chain conveyor belt 120 is rotated 180° under the combined action of the push plate 210 and the shovel sloping plate 410, thereby drying the side of the vegetable bag with moisture.

[0040] The improvement is that a drive push plate 420 is provided above the shovel inclined plate 410. Several second guide rods 421 are fixedly connected to the side of the drive push plate 420 away from the shovel inclined plate 410. The end of the second guide rod 421 away from the drive push plate 420 is slidably connected to the limiting baffle 412. A spring 422 is sleeved on the outer side of the second guide rod 421 between the drive push plate 420 and the limiting baffle 412.

[0041] Preferably, a drive block 430 is provided above the shovel inclined plate 410, and a hydraulic rod 431 for driving its own lifting is provided on the top of the drive block 430. The hydraulic rod 431 includes a cylinder and a piston rod. The cylinder is fixedly connected to the lifting mounting frame 130, and the piston rod is fixedly connected to the top of the drive block 430. Several third guide rods 432 are fixedly connected to the top of the drive block 430, and the end of the third guide rod 432 away from the drive block 430 is slidably connected to the lifting mounting frame 130.

[0042] The top of the drive push plate 420 is fixedly connected to a pressure bearing seat 423. The top of the pressure bearing seat 423 is provided with a pressure bearing inclined surface 424. The bottom of the drive block 430 is provided with a drive inclined surface 433. The pressure bearing inclined surface 424 and the drive inclined surface 433 slide and fit together.

[0043] With the above structural design, when the vegetable bag moves to the bottom of the shovel inclined plate 410, the piston rod of the hydraulic rod 431 extends out of the cylinder and drives the drive block 430 to move downward. The pressure-bearing inclined surface 424 slides relative to the drive inclined surface 433. The force applied by the drive block 430 to the pressure-bearing inclined surface 424 through the drive inclined surface 433 has two components. One component is in the horizontal direction and is called the horizontal component, and the other component is in the vertical direction and is called the vertical component.

[0044] The horizontal force pushes the pressure seat 423 to move horizontally. At this time, the distance between the drive push plate 420 and the limit baffle 412 is shortened. During this period, the spring 422 is compressed and stores elastic potential energy. At the same time, the vertical force drives the push plate 420 to move downward. The drive push plate 420 then drives the shovel inclined plate 410 to slide downward through the second guide rod 421. When the vegetable bag slides upward along the upper surface of the shovel inclined plate 410, the piston rod of the hydraulic rod 431 is retracted into the cylinder. The drive push plate 420 is then reset under the restoring force of the spring 422. Thus, the drive push plate 420 applies a pushing force towards the upstream side of the chain conveyor belt 120 to the vegetable bag, ensuring that the vegetable bag can be rotated 180°.

[0045] It should be disclosed that the first guide rod 411 is provided with a limit cap at the top, and a third spring is sleeved on the outer side of the first guide rod 411 between the top of the lifting mounting bracket 130 and the limit cap to ensure that the shoveled inclined plate 410 can be reset after sliding down. However, since the third spring is only used to drive the shoveled inclined plate 410 to reset, it belongs to the prior art and is not shown in the accompanying drawings.

[0046] The working principle of this food drying equipment will be explained in more detail below: First, the packaged vegetable bags are placed on the chain conveyor belt 120, and the blocking and pushing component 200 pushes the vegetable bags downstream; the drive motor 330 inside the drying component 300 drives the fan 320 to continuously blow air to dry the moisture on the upper surface of the vegetable bags.

[0047] When the vegetable package moves to the corresponding position of the flipping component 400, the hydraulic rod 431 extends the piston rod to drive the drive block 430 to move downward, and the drive inclined surface 433 slides relative to the pressure bearing inclined surface 424; the generated vertical component force drives the drive push plate 420 to move downward, and drives the shovel inclined plate 410 to slide downward via the second guide rod 421; the horizontal component force pushes the pressure bearing seat 423 to move horizontally, and the spring 422 is compressed to accumulate elastic potential energy.

[0048] After the downward movement, the shovel-shaped inclined plate 410 scoops up the bottom of the downstream end of the vegetable bag, while the upstream end of the vegetable bag is continuously pushed by the push plate 210. Under the combined action of the push plate 210 and the shovel-shaped inclined plate 410, the vegetable bag slides upward along the shovel-shaped inclined plate 410.

[0049] During the upward movement of the vegetable bag, the piston rod of hydraulic rod 431 retracts, and drive block 430 resets upward; spring 422 releases elastic potential energy to drive push plate 420 to reset, and drive push plate 420 applies a pushing force to the vegetable bag towards the upstream side of chain conveyor belt 120, causing the vegetable bag to complete a 180° flip.

[0050] After being flipped, the original bottom of the vegetable bag is now facing upwards, making it easier for the drying component 300 to dry any remaining water stains on that side. The vegetable bag flips and falls onto the surface of the feeding roller 230, and rolls down along the outer surface of the feeding roller 230, creating a gap between the vegetable bag and the upstream side of the push plate 210, ensuring that the vegetable bag can be flipped again by the next shovel inclined plate 410.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
