Description

TECHNICAL FIELD

[0001] The application belongs to the field of chocolate production devices, in particular to a sanitary adhesion-removing steel belt conveyor for chocolate production. BACKGROUND

[0002] The steel belt conveyor is a continuous conveying equipment using high-strength steel belt as the bearing and traction component. It is widely used in the production of food, medicine and other industries due to its characteristics of easy cleaning and not easy to breed bacteria. In the processing industry of chocolate food, the conveying of materials is a key link in the production process. Chocolate, as a heat-sensitive and high-viscosity food raw material, has very high requirements for the temperature control performance, hygiene and stability of the conveying equipment. The steel belt conveyor has been widely used in the field of chocolate processing due to its unique advantages.

[0003] In the process of conveying chocolate products, the chocolate falls on the continuously moving steel belt, which is driven by a speed reducer to continuously convey the steel belt to the other end. When the chocolate reaches the specified position, the chocolate is scraped into the discharge hopper from the steel belt by a scraper to realize the conveying process. However, during this process, a small amount of melted chocolate adheres to the surface of the steel belt due to the easy local melting of the chocolate. The existing solution is to use a scraper to scrape and clean the surface of the steel belt, or to use a Teflon-coated steel belt to reduce the adhesion of chocolate. However, the coating is easy to wear and tear, and needs to be replaced frequently. The scraper may damage the surface of the steel belt.

[0004] A conveying equipment for chocolate production is disclosed in Chinese Patent No. CN115973718A, which includes a support plate, a reinforcing column fixedly connected to one side of the support plate, a second support plate fixedly connected to one end of the reinforcing column, a first roller rotatably connected to the opposite surface of the first and second support plates through a bearing, a second roller also rotatably connected to the opposite surface of the first and second support plates through a bearing, an installation plate fixedly connected to one side of the reinforcing column, and a motor provided on the upper surface of the installation plate. The scraper is driven to move downward by the connecting block, so that the upper end of the scraper is separated from the surface of the conveyor belt to avoid damaging the conveyor belt. This scheme realizes the removal of the adhesion of chocolate residues on the conveyor belt, avoids affecting the smoothness of the conveyor belt operation, and realizes the collection and processing of the chocolate residues on the conveyor belt.

[0005] However, the above-mentioned patent still has the following shortcomings:

[0006] 1. In actual use cases, chocolate residue is sticky and has a certain degree of fluidity. Simply using a scraper or scraper is not enough to effectively remove the chocolate residue from the steel belt surface. Traditional methods increase the pressure of the scraper on the steel belt surface to ensure the scraping effect of removing residue, but this is very easy to damage the steel belt surface. On the other hand, as described in the above patent, moving the scraper away from the conveyor belt surface is not enough to effectively remove residue, thus creating a contradiction.

[0007] 2. Due to the high viscosity and fluidity of chocolate, some chocolate will stick to the surface of the scraper when cleaning residual chocolate with a scraper. As the chocolate residue accumulates on the scraper surface, the chocolate is easily exposed to the air for a long time, which can cause it to spoil and breed bacteria, affecting the hygiene and cleanliness of the conveying equipment. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, this invention addresses the technical problem by using a scraper to effectively remove chocolate residue from the steel strip surface. A cooling fan and nozzles cool the chocolate residue before scraping, hardening and brittle the particles, reducing its stickiness and flowability, making it easier to detach from the steel strip surface. This allows the scraper to efficiently remove the residue, improving the cleanliness of the steel strip surface. The nozzles are positioned at the contact point between the scraper and the steel strip, ensuring that the airflow effectively removes residual debris from the scraper surface during scraping, preventing chocolate residue from adhering to the scraper surface for extended periods. Furthermore, the fan shroud prevents the scraped debris from scattering due to the airflow. The working environment around the equipment is dirty. Operators can adjust the pressure of the scraper on the steel strip surface by turning the push ring to compress or release the second spring. When the pressure between the scraper and the steel strip is appropriate, the PTFE scraper can effectively reduce wear on the steel strip surface, preventing scratches that could harbor bacteria and affect the hygiene of the equipment. At the same time, the elasticity of the second spring ensures that the scraper remains in stable contact with the steel strip surface, preventing the scraper from detaching from the steel strip surface and affecting the continuity of scraping and cleaning. After the steel strip cools down, it is bent with a large radius of rotation. The blower blows room temperature air onto the steel strip to quickly restore it to room temperature, reducing metal fatigue. The cleaning roller and sponge sleeve rotate synchronously to clean the surface of the steel strip, removing water droplets that condense after cooling and preventing water droplets from contaminating or melting chocolate products.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a hygienic de-adhesion steel belt conveyor for chocolate production, comprising:

[0010] A first wheel frame and a second wheel frame, wherein a driven wheel and a driving wheel are rotatably arranged in the first wheel frame and the second wheel frame respectively, and a steel belt is driven between the driven wheel and the driving wheel. A driving element is fixedly connected to one side of the second wheel frame, and the power output end of the driving element is driven to the driving wheel.

[0011] A cooling component is provided inside the first wheel frame below the steel belt, and a scraper component for cleaning residues on the surface of the steel belt is provided inside the first wheel frame below the steel belt.

[0013] The second wheel frame and the bottom of the support are respectively fixedly connected to the support legs, and two sets of guide rollers are rotatably connected to each other. Multiple idler rollers are rotatably connected between the two supports, and each guide roller and idler roller supports the return part of the steel belt.

[0014] Furthermore, the cooling component includes nozzles. Multiple nozzles are evenly distributed inside the first wheel frame below the steel belt. Each nozzle points to the position where the steel belt contacts the scraper component. An air duct is fixedly connected inside the first wheel frame at the corresponding position of the nozzle. The air duct is connected and fixedly connected to the tail of each nozzle. A cooling fan is fixedly connected to the outside of the first wheel frame. One end of the air duct passing through the first wheel frame is connected and fixedly connected to the cooling fan.

[0015] Furthermore, a wind shroud is fixedly connected inside the first wheel frame, the return portion of the steel belt passes through the top of the wind shroud, each nozzle is fixed to the side wall of the wind shroud, the wind shroud completely covers and conceals the scraper component, and a collection box is slidably connected to the bottom of the first wheel frame, the inside of the collection box is in communication with the inside of the wind shroud.

[0016] Furthermore, the scraper component includes a blade bar, with blade bars rotatably connected to the inner walls on both sides of the first wheel frame, and a blade holder fixedly connected between the top ends of the two blade bars. A scraper is fixedly connected to the blade holder, and the cutting edge of the scraper is in contact with the surface of the steel strip.

[0017] Furthermore, a second hinge is fixedly connected to one side of each of the tool holders, and a first hinge is fixedly connected to the bottom inner side of the first wheel frame at the corresponding position of each second hinge. A telescopic rod that can freely extend and retract is connected between the movable end of each first hinge and the movable end of the corresponding second hinge. A push ring is threadedly connected to the outer side of each telescopic rod, and a second spring that surrounds the outer side of each push ring and the movable end of the corresponding second hinge is provided.

[0018] Furthermore, the scraper is made of wear-resistant polytetrafluoroethylene material.

[0019] Furthermore, the driven wheel is assembled from multiple identical sub-components stacked together, and a roller is fixedly connected to the axis of the driven wheel. The two ends of the roller are rotatably connected to the first wheel frame, and the diameter of the driven wheel is in the range of 500-600mm.

[0020] Furthermore, the driven wheel is hollowed out, and through slots are evenly distributed on the annular surface of the driven wheel. Through holes are opened on both sides of the first wheel frame at the corresponding positions of the driven wheel. A communicating vessel covering and communicating with the through holes is fixedly connected to one side of the first wheel frame, and a fan is fixedly connected to the bottom of the communicating vessel.

[0021] Furthermore, a cleaning roller is rotatably connected inside the first wheel frame between the cooling component and the driven wheel.

A tension roller seat is fixedly connected below each slide rod, and a tension roller that rolls relative to the steel belt is rotatably connected to the bottom end of the tension roller seat. The tension roller is located between two guide rollers, and multiple first springs surrounding the outside of the slide rods are provided between the tension roller seat and the pressure plate.

[0023] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] (1) By setting up a scraper, the chocolate residue on the steel belt surface can be scraped and cleaned. The chocolate residue is cooled down by the cooling fan and nozzles before the scraper scrapes and cleans it, making the strong particles hard and brittle, reducing the stickiness and fluidity of the chocolate residue, making it easier to detach from the steel belt surface. This allows the scraper to efficiently remove the residue from the steel belt surface, thereby improving the hygienic and cleanliness of the steel belt surface.

[0025] (2) By setting the nozzle to point at the contact point between the scraper and the steel strip, the airflow blown out by the nozzle can remove residual debris from the scraper surface during the scraping and cleaning process, preventing chocolate crumbs from adhering to the scraper surface for a long time. Furthermore, due to the cover and shielding of the wind hood, the scraped debris will not be scattered around the equipment by the airflow, thus making the working environment dirty.

[0026] (3) Operators can adjust the pressure of the scraper on the steel strip surface by twisting the push ring to compress or release the second spring. When the pressure between the scraper and the steel strip is appropriate, the PTFE scraper can effectively reduce the wear on the steel strip surface when scraping it, and avoid scratches on the steel strip surface that may harbor bacteria and affect the hygiene of the equipment. At the same time, the elasticity of the second spring can ensure that the scraper is always in stable contact with the steel strip surface, and prevent the scraper from detaching from the steel strip surface and affecting the continuity of scraping and cleaning.

[0027] (4) After the steel strip is cooled down, it is bent with a large turning radius. The fan blows room temperature airflow onto the steel strip to quickly restore the steel strip to room temperature, reduce the metal fatigue of the steel strip, and the cleaning roller and sponge sleeve rotate synchronously to clean the surface of the steel strip to remove the water droplets that condense on the surface of the steel strip after cooling, so as to avoid water droplets contaminating or melting the chocolate products.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] like Figures 1-8 As shown, a hygienic de-adhesion steel belt conveyor for chocolate production includes a first wheel frame 10 and a second wheel frame 11. A support 12 is fixedly connected between the two sides of the first wheel frame 10 and the second wheel frame 11. A driven wheel 15, composed of multiple identical sub-components stacked and assembled, is rotatably disposed inside the first wheel frame 10. A driving wheel 16 is rotatably connected inside the second wheel frame 11. A drive element 46 is fixedly connected to one side of the second wheel frame 11, and the power output end of the drive element 46 is drive-connected to the driving wheel 16. A steel belt 14 is drive-connected between the driven wheel 15 and the driving wheel 16. Rotary wheels are mounted on the inner walls of both sides of the first wheel frame 10. A blade holder 39 is connected to the top of the two blade holders 39. A scraper 41 that contacts the surface of the steel strip 14 is fixedly connected to the blade holder 40. Multiple nozzles 31 are evenly distributed inside the first wheel frame 10 below the steel strip 14. Each nozzle 31 points to the position where the scraper 41 contacts the steel strip 14. An air duct 32 is fixedly connected inside the first wheel frame 10 at the corresponding position of the nozzle 31. The air duct 32 is connected and fixedly connected to the tail end of each nozzle 31. A cooling fan 33 is fixedly connected to the outside of the first wheel frame 10. One end of the air duct 32 that extends out of the first wheel frame 10 is connected and fixedly connected to the cooling fan 33.

[0039] By setting up the scraper 41, the chocolate residue remaining on the surface of the steel belt 14 can be scraped and cleaned. The cooling fan 33 and the nozzle 31 cool down the chocolate residue before the scraper 41 scrapes and cleans it, making the strong particles hard and brittle, reducing the stickiness and fluidity of the chocolate residue, making it easier to detach from the surface of the steel belt 14. This allows the scraper 41 to efficiently scrape the residue off the surface of the steel belt 14, thereby improving the hygienic and cleanliness of the steel belt 14 surface.

[0040] like Figures 1-8As shown, a pressure plate 22 is fixedly connected inside the first wheel frame 10 at the inner side of the steel belt 14. Multiple slide rods 21 are slidably connected inside the pressure plate 22. A tension roller seat 20 is fixedly connected below each slide rod 21. A tension roller 19 that rolls relative to the steel belt 14 is rotatably connected to the bottom end of the tension roller seat 20. The tension roller 19 is located between two guide rollers 17. Multiple first springs 23 are arranged between the tension roller seat 20 and the pressure plate 22, surrounding the outside of the slide rods 21.

[0041] By setting tension roller 19, the steel belt 14 can be tensioned, thereby ensuring the stability of the operation of the steel belt 14.

[0042] like Figures 1-8 As shown, a wind cover 30 is fixedly connected inside the first wheel frame 10. The return part of the steel belt 14 passes through the top of the wind cover 30. Each nozzle 31 is fixed to the side wall of the wind cover 30. The wind cover 30 completely covers the scraper component. A collection box 45 is slidably connected to the bottom of the first wheel frame 10. The inside of the collection box 45 is connected to the inside of the wind cover 30.

[0043] By setting up the fan cover 30, the cold air blown out by the nozzle 31 can be more concentrated on the steel belt 14, which improves the cooling speed and the cooling and hardening effect on the chocolate deposits. This avoids the problem that some chocolate deposits will not be cooled and hardened and will stick to the surface of the steel belt 14 or the surface of the scraper 41 when the scraper 41 is scraping and cleaning, thus affecting the subsequent cleaning work and the cleaning effect.

[0044] Furthermore, by setting the nozzle 31 to point at the contact point between the scraper 41 and the steel belt 14, the airflow blown out by the nozzle 31 during the scraping and cleaning process of the scraper 41 can effectively remove residual debris from the surface of the scraper 41. Moreover, due to the coverage and shielding of the fan shroud 30, the scraped debris will not be scattered around the equipment due to the airflow, thus preventing the working environment from becoming dirty. In addition, the collection box 45 can effectively collect the chocolate crumbs scraped off, making it convenient for operators to collect and dispose of them.

[0045] like Figures 1-8 As shown, a second hinge 35 is fixedly connected to one side of each blade holder 39. A first hinge 34 is fixedly connected to the bottom inner side of the first wheel frame 10 at the corresponding position of each second hinge 35. A telescopic rod 36 that can freely extend and retract is connected between the movable end of each first hinge 34 and the movable end of the corresponding second hinge 35. A push ring 37 is threadedly connected to the outside of each telescopic rod 36. A second spring 38 is provided between each push ring 37 and the movable end of the corresponding second hinge 35 and surrounds the outside of the telescopic rod 36. The scraper 41 is made of wear-resistant polytetrafluoroethylene material.

[0046] By setting the second spring 38 to provide thrust to the blade 39 and the scraper 41, the blade of the scraper 41 can always be in close contact with the surface of the steel strip 14, thereby ensuring the scraping and cleaning effect. By turning the adjusting push ring 37, the pressure applied by the second spring 38 to the scraper 41 can be adjusted, thereby adjusting the pressure applied by the scraper 41 to the surface of the steel strip 14. With the scraper 41 made of polytetrafluoroethylene, the wear of the scraper 41 on the surface of the steel strip 14 can be effectively reduced, thereby improving the service life of the equipment.

[0047] like Figures 1-8 As shown, a roller 24 is fixedly connected to the shaft of the driven wheel 15. The two ends of the roller 24 are rotatably connected to the first wheel frame 10. The diameter of the driven wheel 15 is in the range of 500-600mm. The driven wheel 15 is hollow. Through slots 25 are evenly distributed on the annular surface of the driven wheel 15. Through holes 42 are opened on both sides of the first wheel frame 10 at the corresponding positions of the driven wheel 15. A communicating vessel 43 covering and communicating with the through hole 42 is fixedly connected to one side of the first wheel frame 10. A fan 44 is fixedly connected to the bottom of the communicating vessel 43.

[0048] By setting the driven pulley 15 to a larger diameter, the steel belt 14 can achieve a larger radius of rotation after being cooled by the cold air sprayed from the nozzle 31. This avoids the steel belt 14 becoming hard and brittle after cooling and then experiencing metal fatigue due to a smaller radius of rotation, thereby improving the service life of the equipment. At the same time, the fan 44 continuously blows room temperature air into the driven pulley 15, allowing the steel belt 14 to quickly return to room temperature after cooling, further reducing metal fatigue during the rotation of the steel belt 14.

[0049] like Figures 1-8 As shown, a cleaning roller 26 is rotatably connected inside the first wheel frame 10 between the cooling component and the driven wheel 15. A sponge sleeve 27 is sleeved on the outside of the cleaning roller 26. The sponge sleeve 27 is in close contact with the surface of the steel belt 14. A sprocket 28 is fixedly connected to the end of the roller 24 and the end of the cleaning roller 26 that extends out of the first wheel frame 10, respectively. A chain 29 is connected between the two sprockets 28.

[0050] After cooling, water droplets easily condense on the surface of the steel belt 14. If not treated, the chocolate products may melt or become contaminated when the steel belt 14 rotates and carries them again. After the steel belt 14 is cooled and scraped cleaned, the water droplets condensed on the surface of the steel belt 14 are cleaned by the cleaning roller 26 and the sponge sleeve 27. In addition, the fan 44 acts on the steel belt 14 through the through groove 25 to quickly restore it to room temperature, which can also reduce the problem of water droplets condensing on the surface of the steel belt 14.

[0051] In this embodiment, initially, the operator sets up the patent at a designated location. The first wheel frame 10 corresponds to the feeding device, while the second wheel frame 11 corresponds to the unloading position. According to actual production needs, the entire device can be tilted to meet the material conveying requirements of different height differences.

[0052] Before starting work, the operator can adjust the pressure of the scraper 41 on the surface of the steel strip 14 by turning the push ring 37 to compress or release the second spring 38. When the pressure between the scraper 41 and the steel strip 14 is properly adjusted, the PTFE scraper 41 can effectively reduce the wear on the surface of the steel strip 14, preventing scratches on the surface of the steel strip 14 from harboring bacteria and affecting the hygiene of the equipment. At the same time, the elasticity of the second spring 38 can ensure that the scraper 41 is always in stable contact with the surface of the steel strip 14, preventing the scraper 41 from detaching from the surface of the steel strip 14 and affecting the continuity of scraping and cleaning.

[0053] During operation, the drive element 46 is activated to make the steel belt 14 rotate continuously, conveying the material from one end of the first wheel frame 10 to the other end of the second wheel frame 11. During this process, the tension roller 19 uses the elasticity of the first spring 23 to apply pressure to the steel belt 14. The guide rollers 17 on both sides of the tension roller 19 tension the steel belt 14, ensuring the stability of the steel belt 14 during operation. During the operation of the steel belt 14, the guide rollers 17 and the idler rollers 18 support the return part of the steel belt 14 to prevent the steel belt from falling and shaking.

[0054] During the operation of the steel belt 14 conveying chocolate products, some chocolate melts and adheres to the surface of the steel belt 14, making it difficult to clean. At the same time as the drive element 46 is started, the cooling fan 33 and the blower 44 are also started. The cooling fan 33 continuously blows out cold air and delivers it to each nozzle 31 through the air duct 32. The cold air is sprayed out from the nozzle 31 and blown into the air hood 30 and towards the contact position between the steel belt 14 and the scraper 41. As the steel belt 14 continuously passes through the air hood 30, the surface of the steel belt 14 is continuously cooled, which makes the chocolate residue on the surface of the steel belt 14 harden and become brittle, reduces the stickiness of the chocolate residue and eliminates its fluidity. This makes it easier for the scraper 41 to peel the chocolate residue off the surface of the steel belt 14 when scraping and cleaning it.

[0055] When the cooled and hardened chocolate residue is scraped by the scraper 41, it will break into fragments and fall off the surface of the steel strip 14. Compared with the traditional method of simply scraping the surface of the steel strip 14 with a scraper, it can remove chocolate residue more comprehensively and efficiently, and is less likely to have problems such as incomplete scraping or residue adhering to the scraper 41, which will affect subsequent cleaning.

[0056] Furthermore, since the nozzle 31 is directly pointed at the contact point between the scraper 41 and the steel strip 14, the airflow blown out by the nozzle 31 can help clean the surface of the scraper 41, preventing chocolate crumbs from accumulating on the blade of the scraper 41 for a long time. At the same time, the fan shroud 30 can concentrate the cold air blown out by the nozzle 31, reducing cold air leakage and making the cold air more concentrated on the scraping and cleaning area of ​​the scraper 41, improving the cooling efficiency of the chocolate residue. It can also prevent the scraped chocolate crumbs from flying around with the airflow and making the working environment dirty. The scraped chocolate crumbs fall directly into the collection box 45. When the collection box 45 is nearly full, the operator can slide out the collection box 45 to dispose of the collected chocolate crumbs in a unified manner.

[0057] After the steel belt 14 is scraped and cleaned by the scraper 41, it passes through the fan cover 30 and turns upwards through the driven wheel 15 to carry and convey the chocolate products again. Since the steel belt 14 is made of metal, its material is prone to hardening after cooling. By setting a large diameter of 500-600mm, the cooled steel belt 14 can run with a large turning radius, avoiding the problem of metal fatigue caused by the steel belt 14 hardening due to cooling bending with a small turning radius, which would eventually lead to cracks or direct breakage of the steel belt 14.

[0058] Meanwhile, the fan 44 continuously blows ambient air into the hollow driven wheel 15. The ambient air acts on the steel belt 14 through the through groove 25, allowing the steel belt 14 to quickly return to room temperature and further reduce metal fatigue of the steel belt 14. At the same time, the sprocket 28 and chain 29 drive the cleaning roller 26 and the sponge sleeve 27 to rotate synchronously and clean the surface of the steel belt 14 to remove water droplets that condense on the surface of the steel belt 14 after cooling, so as to avoid water droplets contaminating or melting the chocolate products.

[0059] The aforementioned refrigeration fan 33, fan 44, drive element 46, etc. are mature existing technologies. The structures in the attached drawings are only for illustration and will not be described in detail here.
