Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0034] Referring to Figures 1 to 4 , the embodiments of the present utility model propose a three - layer sandwich protein bar packaging and conveying device, including a material sorting mechanism 100, a turntable 200, and a packaging mechanism 300. The material sorting mechanism 100 and the packaging mechanism 300 are respectively used for sorting operations and packaging operations of protein bars, and the two are docked through the turntable 200. Specifically:

[0035] The material feeding mechanism 100 is provided with a first conveyor belt 101, a first blowing module and a second conveyor belt 102. The feeding end of the second conveyor belt 102 is aligned with and close to the discharging end of the first conveyor belt 101. The first blowing module is provided with an air outlet between the first conveyor belt 101 and the second conveyor belt 102. The second conveyor belt 102 is set as a weighing conveyor belt;

[0036] The turntable 200 is rotatably arranged horizontally at the discharging end of the second conveyor belt 102. A plurality of supporting parts 201 are arranged along the circumferential direction of the turntable 200. The supporting parts 201 are rotatably connected to the turntable 200, so that the far center end of the supporting part 201 can swing up and down to adjust the inclination angle, and the horizontal height of the far center end of the supporting part 201 is always lower than the height of the discharging end of the second conveyor belt 102. A plurality of idler rollers 202 are rotatably arranged on the upper surface of the supporting part 201, and the plurality of idler rollers 202 are arranged in sequence along the radial direction of the turntable 200;

[0037] The packaging mechanism 300 and the material feeding mechanism 100 are arranged on one side of the turntable 200 in a way of angular dislocation relative to the turntable 200. The horizontal height of the feeding end of the packaging mechanism 300 is always lower than the horizontal height of the far center end of the supporting part 201, and a traction assembly 301 is arranged on the side of the packaging mechanism 300 close to the turntable 200. The traction assembly 301 can traction the far center end of the supporting part 201 to swing downwards.

[0038] During operation, the three-layer sandwich protein bar is fed into the first conveyor belt 101 of the material feeding mechanism 100. When it enters the second conveyor belt 102 from the first conveyor belt 101, the first blowing module blows and cleans the three-layer sandwich protein bar. Then the second conveyor belt 102 weighs it. After weighing, the second conveyor belt 102 conveys the three-layer sandwich protein bar to the supporting part 201. If the weight meets the requirements, the turntable 200 rotates to align the three-layer sandwich protein bar with the packaging mechanism 300, and the traction assembly 301 is used to traction the far center end of the supporting part 201 to swing downwards until it inclines downwards, so that the three-layer sandwich protein bar slides down onto the packaging mechanism 300 under the action of gravity and is conveyed by the packaging mechanism 300. If the weight does not meet the requirements, the turntable 200 rotates to other angles, and the three-layer sandwich protein bar can be discharged automatically or manually.

[0039] The three-layer sandwich protein bar packaging and conveying equipment of this embodiment is provided with a material feeding mechanism 100 and a packaging mechanism 300 at the same time, which can not only clean and weigh the protein bar, but also package the protein bar, reducing the number of equipment and being beneficial to reducing the equipment cost.

[0040] Moreover, the material handling mechanism 100 can clean the particles and dust attached to the surface of the protein bar through the first blowing module, and then weigh it, which is beneficial to improving the accuracy of weighing judgment, ensuring the gram weight requirement of the protein bar, and improving the production quality.

[0041] At the same time, the material handling mechanism 100 conveys the protein bar in the form of a conveyor belt. During the conveying process, the protein bar basically does not collide or rub, and will not damage the surface quality of the protein bar during this conveying process, nor will new particles and dust be peeled off from the protein bar. The material handling mechanism 100 is docked with the packaging mechanism 300 through the turntable 200. The turntable 200 uses the idler 202 to support the protein bar. When the protein bar meets the requirements, it is directly rotated to the docking packaging mechanism 300 through the turntable 200, and the protein bar is discharged through the inclined support portion 201. When it does not meet the requirements, it can be rotated to a set angle through the turntable 200 for discharge. During this period, the turntable 200, the idler 202 and gravity are used to cooperate to realize the transfer and discharge of the protein bar. The protein bar is stationary relative to the turntable 200 during the rotation of the turntable 200. Therefore, the conveying distance of the protein bar is shortened, and the situation that the protein bar is easily damaged during the conveying process can be effectively alleviated.

[0042] In summary, the three-layer sandwich protein bar packaging and conveying equipment of this embodiment can carry out protein bar material handling and packaging at the same time, reduce the equipment cost, and can alleviate the damage of the protein bar during the conveying process, improving the production quality.

[0043] The specific weighing design of the second conveyor belt 102 can be set with reference to relevant existing technologies. For example, the belt scale described in the Chinese utility model patent with the authorization announcement number CN209894312U will not be described in detail here.

[0044] In this embodiment, the packaging mechanism 300 and the material handling mechanism 100 are arranged on one side of the turntable 200 in an angular misalignment manner relative to the turntable 200, that is, the packaging mechanism 300 and the material handling mechanism 100 are distributed around the turntable 200. For example Figure 3 As shown, the packaging mechanism 300 and the material handling mechanism 100 are symmetrically distributed on both sides of the turntable 200, so that the support portion 201 just docks with the packaging mechanism 300 after rotating 180° in the position state of docking with the material handling mechanism 100.

[0045] In some embodiments of the present invention, a lever 203 is further provided at the distal end of the support portion 201. The lever 203 is located below the idler 202. The traction assembly 301 is provided with a first traction portion 3011 that can be adjusted up and down. The first traction portion 3011 is provided with a first relief groove 3012. The lever 203 can enter and exit the first relief groove 3012 during the rotation of the turntable 200.

[0046] When the turntable 200 rotates until the supporting part 201 carrying the protein bar is aligned with the packaging mechanism 300, the lever 203 is just located in the first clearance groove 3012. It is only necessary to control the first traction part 3011 to descend, and then the lever 203 can be pulled down to make the distal end of the supporting part 201 flip downward. If the weight of the protein bar does not meet the requirements, the lever 203 can rotate with the turntable 200 and pass through the first clearance groove 3012 to avoid interference.

[0047] like Figure 3 As shown, the turntable 200 is circumferentially provided with 8 supporting parts 201. Every time the turntable 200 rotates 45°, the supporting part 201 docked by the material handling mechanism 100 and the packaging mechanism 300 is switched. After the protein bar is weighed, the system records whether the protein bar meets the gram weight requirement and the supporting part 201 that the protein bar enters. When the turntable 200 rotates to align the supporting part 201 with the packaging mechanism 300, the lever 203 enters the first yielding groove 3012 of the first traction part 3011. If the current protein bar recorded by the system meets the gram weight requirement, the system controls the first traction part 3011 to move downward, pulls the lever 203 to move downward, causes the supporting part 201 to flip downward, and the protein bar rolls onto the packaging mechanism 300 under the action of gravity, and is transported away by the conveyor belt of the packaging mechanism 300.

[0048] Specifically, the lever 203 is an L-shaped structure, with its upper end hinged to the supporting portion 201 and its lower end extending outward (away from the axis direction of the rotating disk 200). Since the supporting portion 201 is turned upside down during the pulling process, the lever 203 is hinged in this embodiment so that the lever 203 can change its angle relative to the supporting portion 201, which helps to ensure the cooperation between the lever 203 and the first pulling portion 3011.

[0049] In some embodiments of the present invention, the packaging mechanism 300 is provided with a frame. The traction assembly 301 is also provided with a traction drive unit, the first traction unit 3011 is slidably connected to the frame, the traction drive unit is fixed on the frame and transmission-connected to the first traction unit 3011, and is used to control the lifting and lowering adjustment of the first traction unit 3011.

[0050] The traction drive unit can be configured as a cylinder drive structure, or as a motor lead screw or other drive forms, which will not be elaborated in detail here.

[0051] It is understandable that, in this embodiment, by setting the turning traction force of the supporting part 201 on the packaging mechanism 300, it is helpful to reduce the weight of the turntable 200, thereby helping to extend the service life and improve the stability of the turntable 200. In addition, since a plurality of supporting parts 201 are provided on the turntable 200, it is helpful to reduce the equipment cost.

[0052] In some embodiments of the present utility model, a reset portion is provided between the turntable 200 and the supporting portion 201, and the reset portion is used to keep the distal end of the supporting portion 201 at the top of the up-and-down adjustment stroke range.

[0053] Since the supporting portion 201 needs to support the protein bar for transportation and only flips downward when discharging the protein bar, in this embodiment, by providing a reset portion to keep the supporting portion 201 at the top of the up-and-down flipping stroke range without external force, the stability when supporting the protein bar can be effectively ensured. At the same time, it helps to streamline the structure and control, which is beneficial to controlling the equipment cost.

[0054] Specifically, the reset portion can be in the form of a tension spring acting on the supporting portion 201, or in the form of a compression spring acting on the supporting portion 201, or in the form of a torsion spring or other structural forms.

[0055] In some embodiments of the present utility model, mounting seats 2022 are provided on both sides of the supporting roller 202 in the axial direction of the turntable 200. One side of the mounting seat 2022 close to the center of the turntable 200 is rotatably connected to the turntable 200, the supporting roller 202 is rotatably connected to the mounting seat 2022, and the reset portion is connected between the mounting seat 2022 and the turntable 200.

[0056] In this embodiment, the mounting seat 2022 is provided to mount the supporting roller 202, and at the same time, the mounting seat 2022 is used to facilitate the connection of the reset portion, which is beneficial to improving the overall stability of the supporting portion 201.

[0057] In some embodiments of the present utility model, a spacing is provided between two adjacent supporting rollers 202, a limiting seat 205 is provided above the mounting seat 2022 on the turntable 200, and the mounting seat 2022 abuts against the limiting seat 205 under the action of the reset portion.

[0058] It can be understood that each time the supporting portion 201 is pulled and flipped downward, it will be reset upward under the action of the reset portion. In this embodiment, by providing the limiting seat 205 to perform upward limit on the supporting portion 201, the position consistency of the supporting portion 201 can be ensured, which is convenient for transporting the protein bar. At the same time, each time it abuts against the limiting seat 205 during upward movement, the supporting portion 201 will generate a certain vibration, which can clean the possible residual protein bar residues on the supporting roller 202 and make them fall from the spacing between two adjacent supporting rollers 202.

[0059] In some embodiments of the present utility model, a food-grade silica gel layer or a food-grade silica gel sleeve 2021 is provided on the surface of the supporting roller 202.

[0060] It can be understood that in the food industry, traditional idlers 202 usually adopt the form of smooth rollers. In this way, when the protein bars are fed in, it is easy for the protein bars to slide relative to the idlers 202, which easily affects the surface quality of the protein bars. In this embodiment, by setting a food-grade silicone structure, on the one hand, it can improve food hygiene, and on the other hand, it can increase the friction between the idlers 202 and the protein bars, so that the linear speed of the idlers 202 is the same as the feeding speed of the protein bars, avoiding sliding friction.

[0061] Preferably, the rotation of the idler 202 itself is realized by a high-sensitivity bearing structure to minimize the wear of the idler 202 on the protein bars. That is, when the protein bars enter and exit, the idler 202 can be easily driven to rotate, and the idler 202 will not cause wear to the protein bars.

[0062] In some embodiments of the present utility model, a limiting portion 204 is convexly provided upward at the proximal end of the supporting portion 201, and the limiting portion 204 is a food-grade silicone structure.

[0063] Since the protein bars enter the supporting portion 201 from the distal end of the supporting portion 201 by relying on the conveying of the second conveyor belt 102 and the action of gravity, the protein bars will naturally move to the proximal end of the supporting portion 201. By setting the limiting portion 204 with a food-grade silicone structure in this embodiment, the protein bars can be positioned, and at the same time, food hygiene conditions can be ensured. Since the food-grade silicone is an elastic material, it has a buffering effect when the protein bars abut, and can prevent the protein bars from being damaged.

[0064] In some embodiments of the present utility model, the three-layer sandwich protein bar packaging and conveying device further includes an NG discharging mechanism. The NG discharging mechanism and the sorting mechanism 100 and the packaging mechanism 300 are arranged on one side of the turntable 200 in an angular dislocation manner relative to the turntable 200. A second traction portion is provided at the end of the NG discharging mechanism close to the turntable 200 in a liftable and adjustable manner, and the second traction portion can traction the distal end of the supporting portion 201 to move downward.

[0065] When the protein bars that do not meet the weight requirement recorded by the system are aligned with the NG discharging mechanism, the system controls the second traction portion to move downward, so that the supporting portion 201 turns downward, and the protein bars roll onto the NG discharging mechanism under the action of gravity and are discharged under the conveying action of the NG discharging mechanism.

[0066] It can be understood that the second traction portion can be set with reference to the structure and driving form of the first traction portion, so as to simplify the structural design and reduce the development cost.

[0067] By setting the NG discharging mechanism in this embodiment to discharge the protein bars that do not meet the weight requirement, full-automatic production can be realized and the labor cost can be reduced.

[0068] In some embodiments of the present utility model, the packaging mechanism 300 is a vacuum inflation packaging mechanism. Its specific structure can be set with reference to relevant existing technologies and will not be specifically elaborated here.

[0069] In some embodiments of the present utility model, a second blowing module is arranged above the turntable 200. The second blowing module faces the NG discharging mechanism, so that when the supporting part 201 rotates to pass through the position of the NG discharging mechanism, the wind blowing area passing through the second blowing module can blow on the supporting part 201 to clean the supporting part 201.

[0070] The process of producing the three-layer sandwich protein bar by using the above three-layer sandwich protein bar packaging and conveying equipment includes the following steps:

[0071] s1: Mix raw materials such as composite protein powder (including whey protein isolate, soy protein isolate, collagen peptide powder, whey protein concentrate, milk protein concentrate), vegetable oil, glycerol, fructooligosaccharide, sorbitol solution, maltitol solution, polydextrose, oat fiber powder, pea fiber powder, fruit and vegetable fiber powder, resistant dextrin, etc. evenly, and press them into shape to obtain the embryo layer material.

[0072] s2: Stir raw materials such as sorbitol solution, maltitol solution, polydextrose, glycerol, vegetable oil, cocoa powder, fruit powder, etc. evenly under heating conditions to obtain the soft core material.

[0073] s3: After extruding and forming the embryo layer material obtained in s1 and the soft core material obtained in s2, sprinkle granular soy protein on its surface, apply a cocoa flavor coating, and cure the coating with cold air.

[0074] s4: Feed the shaped three-layer sandwich protein bar into the first conveyor belt 101. Under the conveyance of the first conveyor belt 101, the protein bar crosses the first conveyor belt 101 and enters the second conveyor belt 102. When the protein bar enters the second conveyor belt 102 from the first conveyor belt 101, the first blowing module blows and cleans the protein bar to clean off the particles that are not completely adhered to the surface of the protein bar and the debris that may be generated during transportation. The cleaned particles and debris directly fall through the gap between the first conveyor belt 101 and the second conveyor belt 102.

[0075] s5: After the current protein bar completely enters the second conveyor belt 102, weigh the single cleaned protein bar to determine whether the weight of the current protein bar reaches the set weight.

[0076] s6: Feed the weighed protein bar onto the supporting part 201 of the turntable 200. The system records whether the protein bar carried on the supporting part 201 meets the weight standard, and then the turntable 200 rotates to align the next supporting part 201 with the second conveyor belt 102 to continue to receive the protein bars weighed by the second conveyor belt 102.

[0077] S7: When the turntable 200 rotates to align the supporting portion 201 with the packaging mechanism 300 and the weight of the protein bar supported meets the standard, the supporting portion 201 is pulled to turn downward to discharge the protein bar to the packaging mechanism 300, and the conveyor belt of the packaging mechanism 300 rotates synchronously to cooperate with receiving the protein bar; if the weight of the protein bar supported is insufficient, no discharging is performed until the supporting portion 201 is aligned with the NG discharging mechanism, and the protein bar with insufficient weight is discharged to the NG discharging mechanism;

[0078] S8: The packaging mechanism 300 performs vacuum inflation packaging on the fed protein bars.

[0079] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Various changes can be made without departing from the gist of the present utility model within the knowledge scope of those of ordinary skill in the art to which it pertains. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
