Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing, specifically to an anti-stick guide strip for a nutrition bar conveyor belt. Background Technology
[0002] In the modern food processing industry, conveyor belt systems are widely used due to their simple structure, high degree of automation, and strong adaptability, especially in the continuous production of highly adhesive foods such as nutrition bars, chocolates, and candies, where they are one of the core pieces of equipment. However, foods containing sugar and oil, such as nutrition bars, are prone to sticking to the conveyor belt and its guiding components during transport, causing product residue, production line jams, and frequent shutdowns for cleaning, which seriously affects production efficiency and food safety and hygiene.
[0003] The main causes of adhesion include: First, improper conveyor belt tension. Excessive tension increases friction between the belt surface and the material, leading to adhesion and potential belt damage; excessive tension causes belt misalignment, skipping sections, and increases the risk of foreign matter accumulation. Second, excessively high conveying speeds rapidly increase tangential friction between the material and the belt surface, making it easier for sticky substances to accumulate. Third, fluctuations in humidity and temperature in the production workshop can cause the conveyor belt material to expand or contract due to moisture, altering its surface properties and exacerbating adhesion. To reduce adhesion, the industry typically uses rigid, non-adhesive materials, such as polytetrafluoroethylene (PTFE), ultra-high molecular weight polyethylene (UHMW-PE), or food-grade polyurethane, to create fixed guide strips at the guide strips or side strips. These passively prevent adhesion by reducing the contact area between the material and the guide components (conveyor belt, etc.). However, these guide strips often lack active cleaning and anti-adhesion structures.
[0004] Therefore, there is an urgent need to design a new type of anti-stick guide strip for nutrition bar conveyor belts to meet the needs of modern food production and processing. Utility Model Content
[0005] The purpose of this utility model is to provide an anti-stick guide strip for a nutrition bar conveyor belt, which can effectively prevent nutrition bars from sticking together during the conveying process and avoid product damage caused by poor conveying.
[0006] The technical solution adopted by this utility model to solve the above problems is: a nutrient bar conveyor belt anti-stick guide strip, including side strips fixedly arranged in pairs on the conveyor belt, a movable strip between the two sets of side strips, and several impact units that drive the movable strip to bounce intermittently below it. The impact unit includes a spring and a first magnetic element. Several second magnetic elements are arranged along the circumference of the outer side of the pulley adapted to the conveyor belt. The first magnetic element and the second magnetic element attract each other.
[0007] Preferably, a plurality of flexible partitions are arranged below the movable strip along its length, and the first magnetic element is slidably disposed between two sets of flexible partitions.
[0008] Preferably, the outer periphery of the first magnetic component is fitted with sound-insulating cotton.
[0009] Preferably, the movable strip is provided with a plurality of flexible pads corresponding to the first magnetic element.
[0010] Preferably, a corrugated tube is provided between the first magnetic component and the flexible gasket, and the flexible gasket has micropores that communicate with the corrugated tube.
[0011] Preferably, the flexible pad has several hemispherical protrusions arranged circumferentially on its outer surface.
[0012] Preferably, the upper edge of the side strip away from the movable strip has a rounded corner structure.
[0013] Compared with the prior art, this utility model has the following advantages and effects:
[0014] This invention features movable strips that can be partially lifted between paired side strips of the conveyor belt, combined with impact units arranged below. This allows for the active removal of adhering substances during the transport of nutrition bars, effectively preventing the nutrition bars from sticking together on the conveyor belt due to sugar and oil components. In addition, by setting flexible partitions to limit the first magnetic component, interference between impact units is prevented when the conveyor belt is flipped or tilted, ensuring the stable and reliable operation of the impact units.

Detailed Implementation
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0021] Example:
[0022] See Figure 1 - Figure 4 In this embodiment, an anti-sticking guide strip for a nutrient bar conveyor belt 11 is provided. Specifically, it is used to remove and guide the adhesion of undivided block nutrient bars during high-speed continuous conveying on the conveyor belt 11. Specifically, it includes: side strips 12 fixedly arranged in pairs on the conveyor belt 11, a movable strip 13 between the two sets of side strips 12, and several impact units 14 below the movable strip 13 that drive it to bounce intermittently. The impact unit 14 includes a spring 15 and a first magnetic element 16. Several second magnetic elements 18 are arranged circumferentially on the outer side of the pulley 17 adapted to the conveyor belt 11. The first magnetic element 16 and the second magnetic element 18 attract each other (in this embodiment, both the first magnetic element 16 and the second magnetic element 18 can be magnets).
[0023] Specifically, in this embodiment, before the production line starts, ensure that the conveyor belt 11 and pulley 17 are properly tensioned. The nutrient bars are transported with the conveyor belt 11, and the impact unit 14 passes through the pulley 17 sequentially with the conveyor belt 11. The working principle of the impact unit 14 is as follows: Before the impact unit 14 reaches the pulley 17, the gravity of the first magnetic component 16 is balanced with the elastic force of the spring 15 (without considering the weight of the spring 15 or other influencing factors). When the pulley 17 rotates, the first magnetic component 16 of the impact unit 14 passes through the second magnetic component 18 on the pulley 17. The first magnetic component 16 and the second magnetic component 18 attract each other, driving the spring 15 to compress. Subsequently, the first magnetic component 16 leaves the second magnetic component 18, and the elastic force of the spring 15 is released, driving the first magnetic component 16 to impact the movable bar 13 upwards, removing the nutrient bar residue attached to its outer surface. In this embodiment, the movable strip 13 is in a concave and relaxed state when not impacted, with the side strips 12 protruding from the surface of the movable strip 13 and contacting and supporting the nutrient bar. When the movable strip 13 is impacted, it partially pops outward and protrudes from the side strips 12, allowing the bottom surface of the nutrient bar that is already or about to adhere to the side strips 12 to detach in time. In this embodiment, the nutrient bar is impacted by the movable strip 13 every time it passes the pulley 17. Therefore, the spacing between adjacent pulleys 17 or the density of the second magnetic elements 18 on the pulleys 17 can be adjusted according to the viscosity of the nutrient bar. This increases the impact frequency of the impact unit 14 on the movable strip 13 while keeping the conveying speed constant, ensuring that the nutrient bar is not damaged and maintaining the anti-sticking effect.
[0024] The two ends of the conveyor belt 11 will rotate 180° under the action of the pulleys 17. Under the gravity of the first magnetic component 16, the spring 15 bends downward, and there is interference between adjacent impact units 14. This can easily lead to knots between the springs 15, causing damage to the impact units 14 and affecting the impact effect. In this embodiment, several flexible partitions 21 are arranged along the length of the movable strip 13 below it. The first magnetic component 16 is slidably disposed between two sets of flexible partitions 21. The flexible partitions 21 have a limiting function, so that the first magnetic component 16 can only move between two sets of flexible partitions 21, which can avoid interference between adjacent impact units 14 and ensure that the impact units 14 will not get stuck under high-speed operation. Especially when the conveyor belt 11 is set at an angle, if the flexible partitions 21 are not set, the impact angle of the impact unit 14 will be more inclined, and the impact angle between the first magnetic component 16 and the movable strip 13 will not be perpendicular, affecting the active anti-sticking effect of the impact.
[0025] The outer periphery of the first magnetic component 16 is fitted with sound-insulating cotton 22, so that when the first magnetic component 16 impacts the movable strip 13, it absorbs part of the sound energy. The noise during production needs to be controlled below 70dB to meet the environmental protection and labor protection standards of the workshop.
[0026] The movable bar 13 is provided with a plurality of flexible pads 23 corresponding to the first magnetic element 16, so that the first magnetic element 16 comes into contact with the flexible pads 23 when impacted, providing a buffer when the movable bar 13 bounces up, so as to reduce the damage to the movable bar 13 when the first magnetic element 16 impacts.
[0027] A bellows 24 is provided between the first magnetic component 16 and the flexible gasket 23, and the flexible gasket 23 has micropores 25 that communicate with the bellows 24. On the one hand, when the first magnetic component 16 impacts the movable strip 13, air is discharged from the bellows 24 through the micropores 25, and the bellows 24 is compressed, which can further improve the buffering effect of the first magnetic component 16 on the impact of the movable strip 13; on the other hand, by filling the bellows 24 with an appropriate amount of food-grade silicone oil lubricant, the lubricant in the bellows 24 flows out from the micropores 25 when the first magnetic component 16 impacts, thereby increasing the anti-sticking effect.
[0028] In this embodiment, the outer surface of the flexible pad 23 protrudes beyond the movable strip 13, and the outer surface of the flexible pad 23 is circumferentially arranged with several hemispherical protrusions 26, which further reduces the contact area between the pad and the bottom surface of the nutrient bar. The upper edge of the side strip 12 away from the movable strip 13 is provided with a rounded corner structure 27, which on the one hand reduces the contact area between the movable strip 13 and the nutrient bar during transportation, and on the other hand, the rounded corner structure 27 has a protective function, which can prevent operators from being scratched by sharp edges.
[0029] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
