Description

Technical Field

[0001] The present invention belongs to the technical field of conveyor belt cleaning, and specifically relates to a raw material conveying device for food processing and its conveying method. Background Art

[0002] In the food production industry, the conveyor belt is a key carrier for transporting food raw materials, semi-finished products, and finished products. Its cleaning status is directly related to the quality and safety of food. A clean conveyor belt can not only prevent foreign objects from mixing into food but also effectively avoid the growth of microorganisms, reduce the risk of food contamination, and ensure that food meets strict hygiene standards.

[0003] A patent of Chinese Patent Application CN118529447B discloses a raw material conveying device for food processing, which relates to the technical field of conveying, including: a support frame, on the surface of which a motor is fixedly installed, a roller is fixedly installed at the output end of the motor, and a conveyor belt is drivingly installed on the surface of the roller; an anti-adhesion device, which includes a belt, a brush roller, a short rod, a water tank, a water suction pipe, a nozzle, a round plate, a cylinder, a connecting rod, and a sealing plate. By the rotation of the motor driving the rotation of the roller, and the rotation of the roller driving the rotation of the conveyor belt, the brush roller is rotatably installed on the inner wall of the support frame, one end of the belt is drivingly installed on the surface of the motor, and the other end of the belt is drivingly installed on the circumferential surface of the brush roller. The short rod is fixedly installed at the rotating shaft of the brush roller. By the rotation of the brush roller, the surface of the conveyor belt is cleaned, and at the same time, by intermittently opening the nozzle, water is intermittently sprayed to prevent waste caused by continuous spraying.

[0004] When the external part of food raw materials contains starch, the spraying process will cause the starch to gelatinize rapidly when encountering water. The gelatinized starch forms a highly viscous paste, which tightly adheres to the surface of the conveyor belt. Subsequent wiping operations are difficult to completely remove these pastes, and they will continue to remain on the conveyor belt. As production continues, the residual starch paste accumulates continuously, resulting in the surface of the conveyor belt becoming extremely sticky. Moreover, the starch paste is rich in nutrients, providing an ideal environment for the growth of microorganisms. After a large number of microorganisms reproduce, it is extremely easy to contaminate food raw materials and endanger food safety.

[0005] When facing food raw materials containing syrup, the problem is more prominent. Syrup itself has extremely strong viscosity. Although flushing can remove some syrup, the remaining syrup will still firmly adhere to the surface of the conveyor belt. During the wiping process, due to the extremely high viscosity of the syrup, it is very difficult to completely clean it. Even if the wiping times and intensity are increased, it is difficult to achieve an ideal cleaning effect. The sticky surface of the conveyor belt is prone to adsorbing dust, impurities, etc. in the air, further contaminating food raw materials and reducing product quality.

[0006] Therefore, the present invention provides a raw material conveying device for food processing and its conveying method. Summary of the Invention

At the same time, the distilled and condensed water droplets are relatively clean. By injecting this part of the water resource into the inner wall of the drainage hopper, it can be used to moisten the wiping roller to maintain the cleanliness of the wiping roller. In addition, because this part of the water source contains heat, by wetting the wiping roller with hot water, the evaporation rate of the water inside the wiping roller can be increased after squeezing out the water.

Specific implementation manner

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0023] As Figures 1 to 10 shown, a raw material conveying device for food processing according to the present invention includes a conveying part, a supporting part, a hot compress mechanism, a powder suction mechanism, a scraping mechanism and a wiping mechanism; The conveying part includes a frame 1, a conveyor belt 2 and a drive assembly 3. The conveyor belt 2 is arranged on the side wall of the frame 1 and is driven by the drive assembly 3. Among them, the drive assembly 3 is composed of a drive motor and a drive roller. The drive roller is rotatably arranged on the side wall of the frame 1 and there are multiple drive rollers for tensioning the conveyor belt 2. The output shaft of the drive motor is connected to the center position of the axial end of one of the drive rollers for the drive motor to control the rotation of the drive roller, thereby driving the conveyor belt 2 to rotate. When food is processed, the raw materials fall above the conveyor belt 2 to realize the conveying of the raw materials.

[0024] The supporting part includes an accommodation box 7 and a lifting hopper 15. The accommodation box 7 is fixedly installed on the side wall of the frame 1. Among them, a drain port is provided at the bottom of the accommodation box 7 for sewage discharge. The lifting hopper 15 is slidably arranged inside the accommodation box 7. A cavity is arranged inside the lifting hopper 15, and an opening is provided at the upper end (the end facing the conveyor belt 2).

[0025] The hot compress mechanism includes a heating box 13 and a discharge pipe 17. The heating box 13 is fixedly installed on the inner wall of the accommodation box 7. The inner cavity of the heating box 13 is used to store the cleaning liquid (select pure water). A resistance heater is arranged inside the heating box 13 for heating the cleaning liquid to generate steam.

[0026] The discharge pipe 17 is arranged inside the lifting bucket 15, and one end is connected to the inner cavity of the heating box 13. A control valve (which can be a pressure valve or a check valve) is provided at the connection part of the discharge pipe 17 and the heating box 13. An exhaust port is opened on the outer wall of a section of the discharge pipe 17 located inside the lifting bucket 15. The steam generated inside the heating box 13 is discharged towards the outer wall of the conveyor belt 2 through the exhaust port, so as to apply hot compress to the residues adhered to the outside of the conveyor belt 2.

[0027] The powder suction mechanism includes a powder suction hopper 10 and a connecting pipe 19. The powder suction hopper 10 is slidably arranged inside the accommodating box 7, and a cavity is arranged inside the powder suction hopper 10.

[0028] One end of the connecting pipe 19 is connected to the inner cavity of the powder suction hopper 10, and the other end extends below the liquid level in the inner cavity of the heating box 13. After closing the valve of the discharge pipe 17, the negative pressure chamber is connected to the heating box 13. At this time, the powder suction hopper 10 absorbs the dust outside the conveyor belt 2. After the dust is transported into the heating box 13, it is mixed with the liquid inside the heating box 13 to achieve dust capture and filtration.

[0029] Specifically, when the residue outside the conveyor belt 2 is a viscous substance (such as syrup, grease), the lifting bucket 15 is controlled to fit with the outside of the conveyor belt 2. When the residue outside the conveyor belt 2 is dust (such as starch), the powder suction hopper 10 is controlled to fit with the conveyor belt 2.

[0030] The scraping mechanism includes a connecting rod 25 and a scraping strip 11. The connecting rod 25 is slidably arranged on the inner wall of the accommodating box 7, and the scraping strip 11 is fixedly installed at one end of the connecting rod 25. When cleaning the viscous residue, the scraping strip 11 is controlled to fit with the outer wall of the conveyor belt 2. As the conveyor belt 2 moves, the conveyor belt 2 after hot compress moves to the position of the scraping strip 11, and the residue after hot compress is scraped off by the scraping strip 11 to achieve the cleaning of the viscous residue on the outer wall of the conveyor belt 2 and the preliminary cleaning of the water stains.

[0031] The sliding of the connecting rod 25 is controlled by the air pressure inside the heating box 13. The scraping strip 11 is fixedly installed at one end of the connecting rod 25. When cleaning the viscous residue on the outer wall of the conveyor belt 2, first, the inside of the heating box 13 needs to be heated. The sliding of the connecting rod 25 is controlled by the pressure inside the heating box 13, and then the scraping strip 11 is driven to fit with the conveyor belt 2 to maintain the synchronism of hot compress and scraping.

[0032] The wiping mechanism includes a support roller 35 and a wiping roller 8. The wiping roller 8 is rotatably installed on the inner wall of the accommodating box 7 through the support roller 35. Among them, the support roller 35 is rotatably connected to the inner wall of the accommodating box 7. The wiping roller 8 is made of elastic sponge material. The radial outer wall of the wiping roller 8 is always in contact with the outer wall of the conveyor belt 2. After being scraped by the scraping strip 11, it is wiped by the wiping roller 8 to absorb the remaining water stains outside the conveyor belt 2, keep the surface of the conveyor belt 2 dry, and thus maintain the conveying quality.

[0033] The heat discharged through the drain pipe 17 heats the wiping roller 8. After the wiping roller 8 absorbs the water stains, the water content inside is reduced by heating, thereby maintaining the water absorption effect.

[0034] In this embodiment, when the outside of the conveyor belt 2 is viscous residue, the residue is first hot-compressed, and then the surface of the conveyor belt 2 after hot-compression is scraped. After scraping, it is wiped and the water is absorbed by the wiping roller 8. Compared with the prior art (Chinese Patent Application CN118529447B, a raw material conveying device for food processing), in which only the intermittent spraying and then wiping method is used, the cleaning effect of the viscous residue can be effectively improved, and the hygiene of the conveyed food raw materials can be maintained. When the outside of the conveyor belt 2 is dust residue, the dust is absorbed by the negative pressure in cooperation with the dust suction hopper 10. Compared with the prior art (Chinese Patent Application CN118529447B, a raw material conveying device for food processing), in which the dust is wetted by spraying and then cleaned by wiping, the dust can be prevented from sticking wet, thereby preventing the food raw materials from absorbing water, and thus maintaining the quality of food conveying. It realizes the switching of the cleaning method according to the residue on the outer wall of the conveyor belt 2, improves the scope of application, and at the same time maintains the cleaning effect and the quality of food raw material conveying.

[0035] A control cylinder 14 is fixedly installed on the inner wall of the accommodating box 7. The control cylinder 14 is a common electric telescopic rod. The movable end of the control cylinder 14 is fixedly connected to the bottom surface of the lifting hopper 15. The lifting hopper 15 is controlled to lift by the control cylinder 14. When cleaning the dust, both the lifting hopper 15 and the scraping strip 11 are far away from the conveyor belt 2. At this time, only the dust suction hopper 10 is in contact with the conveyor belt 2, which is used to reduce the frictional loss on the outer wall of the conveyor belt 2.

[0036] A hot-compression layer 12 is fixedly installed on the inner wall of the lifting hopper 15. The hot-compression layer 12 is made of breathable elastic material. In this embodiment, sponge is selected. The hot-compression layer 12 wraps the drain pipe 17. The water vapor discharged from the drain pipe 17 passes through the hot-compression layer 12 and contacts the conveyor belt 2. At the same time, the water droplets condensed upon contact moisten the hot-compression layer 12. Thus, when the conveyor belt 2 moves, while hot-compressing the conveyor belt 2, the wet hot-compression layer 12 wipes and cleans the conveyor belt 2, and preliminarily cleans the viscous residue on the outer wall of the conveyor belt 2.

[0037] An overflow port 16 is opened at the bottom of the lifting hopper 15. The overflow port 16 is used for draining water to prevent the condensed water droplets from accumulating inside the lifting hopper 15.

[0038] As a preferred embodiment of the present invention, a control pump 18 is fixedly installed on the upper end surface of the heating box 13. The control pump 18 is a common micro vacuum water pump, which has the functions of pumping water and pumping air.

[0039] The input end of the control pump 18 extends into the inner cavity of the heating box 13 and is located above the liquid level inside the heating box 13, used to form a negative pressure in the area above the liquid level in the inner cavity of the heating box 13, thereby generating a negative pressure at the powder suction hopper 10 for absorbing the dust residue on the outer wall of the conveyor belt 2.

[0040] A brush mounting groove 27 is provided on the side of the powder suction hopper 10 facing the movement of the conveyor belt 2. The brush mounting groove 27 is used to install plastic brushes. When the powder suction hopper 10 sucks air, air enters through the brush mounting groove 27. During the process of air entry, the plastic brushes are impacted and vibrated to clean the outer wall of the conveyor belt 2, improving the efficiency of dust absorption.

[0041] An installation cylinder 20 is fixedly installed on the upper end surface of the heating box 13. The inner cavity of the installation cylinder 20 is in communication with the inner cavity of the heating box 13. When the inner cavity of the heating box 13 is heated, the internal air pressure increases and at the same time the air pressure in the inner cavity of the installation cylinder 20 increases. A control plug 26 is elastically installed in the inner cavity of the installation cylinder 20. The outer wall of the control plug 26 is in sealing fit with the inner wall of the installation cylinder 20, and a spring is provided on the outer wall of the control plug 26. The other end of the spring is connected to the inner wall of the installation cylinder 20.

[0042] The upper end surface of the control plug 26 is fixedly connected to the bottom end of the connecting rod 25. When the air pressure at the bottom of the installation cylinder 20 increases, the control plug 26 slides upward, pushing the connecting rod 25 and the scraping strip 11 to slide until the scraping strip 11 is in contact with the conveyor belt 2, so as to scrape the conveyor belt 2 after hot compress.

[0043] As a preferred embodiment of the present invention, guide rails 21 are fixedly installed on the inner wall of the accommodating box 7, and dovetail grooves are provided in the guide rails 21.

[0044] At least two guide rails 21 are provided. In this embodiment, four guide rails 21 are provided, two in a group, symmetrically arranged on the inner wall of the accommodating box 7.

[0045] Sliding blocks 22 are slidably installed on the inner walls of the guide rails 21. The sliding blocks 22 are dovetail blocks. The outer wall of one of the sliding blocks 22 is fixedly connected to the side wall of the powder suction hopper 10, and the outer wall of the other sliding block 22 is fixedly connected to the side wall of the scraping strip 11, used to define the sliding trajectories of the powder suction hopper 10 and the scraping strip 11.

[0046] A transmission gear 24 is rotatably installed on the inner wall of the accommodating box 7. Transmission racks 23 are symmetrically meshed on the radially outer wall of the transmission gear 24. The transmission racks 23 are used to control the sliding of the sliding blocks 22. As Figure 6 shown, when the powder suction hopper 10 rises, the scraping strip 11 descends, and when the scraping strip 11 rises, the powder suction hopper 10 descends. When absorbing the dust outside the conveyor belt 2, the inside of the heating box 13 is not heated, and the spring pushes the control plug 26 to slide down, driving the scraping strip 11 to slide down and the powder suction hopper 10 to rise.

[0047] A support cylinder 5 is fixedly installed at the center position of the axial end of the support roller 35. The support cylinder 5 penetrates through the side walls of the accommodation box 7 and the frame 1 and is rotatably connected to the side walls of the accommodation box 7 and the frame 1. A bearing is provided at the contact position between the support cylinder 5 and the accommodation box 7 to provide support for the support roller 35.

[0048] A control motor 4 is fixedly installed on the outer wall of the frame 1. The control motor 4 controls the rotation of the support cylinder 5 through a transmission member. The control motor 4 is a common servo motor, and the transmission member is selected as a common belt and pulley transmission. The control motor 4 controls the rotation of the support cylinder 5 through the cooperation of the belt and the pulley, and then drives the support roller 35 and the wiping roller 8 to rotate. Thus, after the conveyor belt 2 is scraped, the outer wall of the conveyor belt 2 is wiped to keep the conveyor belt 2 clean.

[0049] As a preferred embodiment of the present invention, a guiding frame 34 is fixedly installed on the inner wall of the accommodation box 7. A connecting frame 33 is elastically installed on the inner wall of the guiding frame 34. The outer wall of the connecting frame 33 is slidably attached to the inner wall of the guiding frame 34. Among them, a spring is provided on the outer wall of the connecting frame 33, and the other end of the spring is fixedly connected to the inner wall of the guiding frame 34.

[0050] An arc-shaped piece 31 is fixedly installed on the side wall of the connecting frame 33. Pull the connecting frame 33 to make the arc-shaped piece 31 away from the outer wall of the wiping roller 8, and then release it. By hammering the wiping roller 8 with the arc-shaped piece 31, a mechanical impact force can be generated, causing the fibers of the wiping roller 8 to vibrate and rub. This friction can effectively break the adhesion between the stains and the clothing fibers, so that the stains fall off and are carried away by water, thereby improving the cleaning cleanliness and maintaining the cleaning effect of the wiping roller 8.

[0051] A drain hopper 9 is fixedly installed on the inner wall of the accommodation box 7. A drain port is opened at the bottom of the drain hopper 9 facing one side of the wiping roller 8. Clean water source is injected into the drain hopper 9, and the drain hopper 9 drains water towards the wiping roller 8. After draining, the wiping roller 8 is hammered by the arc-shaped piece 31 to keep the wiping roller 8 clean.

[0052] A transmission block 32 is fixedly installed on the outer wall of the connecting frame 33. When the support cylinder 5 rotates, it drives the transmission block 32 to rotate.

[0053] A pressing block 30 for pressing the transmission block 32 is fixedly installed on the radial outer wall of the support cylinder 5. The outer wall of the pressing block 30 is inclined. When the support cylinder 5 rotates, the transmission block 32 and the connecting frame 33 are pushed by the pressing block 30 until the transmission block 32 and the pressing block 30 are separated. At this time, the spring releases its elastic potential energy to control the arc-shaped piece 31 to hammer the outer wall of the wiping roller 8.

[0054] The inner wall of the accommodation box 7 is rotatably installed with a scraping plate 28 through a torsion spring. One end of the scraping plate 28 constantly presses against the radial outer wall of the wiping roller 8. As the wiping roller 8 rotates, the area of the wiping roller 8 that is hammered moves to the position of the scraping plate 28. By scraping and squeezing the outer wall of the wiping roller 8 through the scraping plate 28, the extrusion drainage of the wiping roller 8 is realized, and the moisture of the wiping roller 8 is reduced.

[0055] The inner wall of the support cylinder 5 is installed with a support pipe 29 through a bearing. The inner wall of the support roller 35 is rotatably installed with a storage cylinder 37 communicating with the inner cavity of the support pipe 29. Both axial ends of the storage cylinder 37 are provided with the support pipe 29.

[0056] The radial outer wall of the storage cylinder 37 is fixedly installed with a heat sink 36. The heat sink 36 is made of copper plate and is located above the scraping plate 28. The heat sink 36 is heated, so as to heat the wiping roller 8 that is extruded and drained from the inside to the outside, further drain the water, and reduce the water content of the wiping roller 8 when wiping the conveyor belt 2.

[0057] There are multiple control pumps 18. The input end of one of the control pumps 18 is connected to the support pipe 29 through a three-way valve, and the output end extends to the inside of the drainage hopper 9 through a conduit. When cleaning viscous residues, this control pump 18 absorbs clean water and injects water into the drainage hopper 9 to facilitate wetting the wiping roller 8.

[0058] One end of the discharge pipe 17 far from the heating box 13 is fixedly connected with an adapter pipe 6. The other end of the adapter pipe 6 is rotatably connected to the central position of the axial end of the support pipe 29. Part of the water droplets condensed in the discharge pipe 17 enter the inside of the support pipe 29 and the storage cylinder 37 through the negative pressure generated by the control pump 18. This part of the water droplets contains residual heat. On the one hand, it can heat the heat sink 36 to realize the heating and drying of the wiping roller 8. At the same time, the distilled and condensed water droplets are relatively clean. By injecting this part of the water resource into the inner wall of the drainage hopper 9 to wet the wiping roller 8, the cleanliness of the wiping roller 8 can be maintained.
