DETAILED DESCRIPTION

[0032] The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0033] The present application relates to a precise conveying mechanism 3 for sauce, as shown in the drawings, comprising a feeding pipe 31 and a screw 32, the screw 32 being rotatably installed in the feeding pipe 31, and the screw 32 being rotated by an external related screw driving mechanism. Figures 1-7

[0034] The feeding pipe 31 has a front end and a rear end, and the pipe wall near the rear end of the feeding pipe 31 is provided with an inlet 311, and the front end of the feeding pipe 31 is an outlet end 312, and the feeding pipe 31 forms a fully enclosed conveying section 313 between the inlet 311 and the outlet end 312, i.e. the conveying section 313 is a fully enclosed structure. The screw 32 has a thread 321 and a thread groove 322 formed between the teeth of the thread 321, and the inner wall of the conveying section 313 is provided with a gap A of 0.05-0.2mm from the top of the corresponding thread.

[0035] The present conveying mechanism is specially designed for conveying and feeding sauce with certain viscosity, wherein the fully enclosed conveying section 313 of the feeding pipe and the built-in screw 32 constitute a conveying unit for pushing the sauce, the conveying unit has a matching gap of 0.05-0.2mm, which forms an effective and moderate precise space for accommodating the sauce, when the screw rotates, based on the structure of the precise space, the matching gap avoids the problem of blockage or air pocket of the sauce in the precise space, and it is also beneficial for the inner wall surface of the conveying section 313 to cooperate with the thread 321 to form a pushing force wall that effectively overcomes and accurately feeds the internal fluid friction resistance of the sauce, and the two cooperate to effectively and accurately convey the granular sauce.

[0036] Preferred embodiments, as shown in the drawings, include the following: Figure 2 ​As shown, the axial length of the full-walled conveying section 313 is 3-5 times the axial length of the inlet 311.

[0037] The axial length of the inlet 311 and the axial length of the conveying section 313 are related to the effectiveness and accuracy of the conveying, and to some extent, the two have opposite effects. Through research and experiments, the relationship of 3-5 times is preferred, which balances the feeding effect and is more beneficial to the effective and accurate conveying and feeding of viscous sauce.

[0038] The preferred embodiment is as shown in the figure Figures 2-3 As shown, the groove depth of the screw groove 322 of the screw 32 is 2-3 times the particle diameter of the particle sauce.

[0039] The embodiment is mainly aimed at the further improvement of the particle (conventional size) sauce. Through research and experiments, the groove depth of the screw groove 322 is 2-3 times the particle diameter of the particle sauce, which ensures smooth and efficient conveying of the particle sauce, avoids the problem of sauce blockage caused by particles, and maximizes the retention of the particle taste of the sauce.

[0040] The preferred embodiment is as shown in the figure Figures 2-3 As shown, the front end of the screw 32 has a tapered head 323, the bottom diameter of the tapered head 323 is equal to the outer diameter of the thread 321; a plurality of grooves 3231 extending in the axial direction are arranged on the tapered surface of the tapered head 323, and the groove bottom of the groove 3231 is flush with the surface of the shaft body 320 of the screw 32.

[0041] In this way, when the sauce is conveyed from the rear end to the front end, the sauce can be smoothly and gently output under the guidance of the tapered and groove structure, which improves the accuracy of the output, and there is no corner dead angle inside, and there is no sauce retention phenomenon. The groove 3231 is preferably a U-shaped groove structure, which is more beneficial to the smooth conveying of the sauce.

[0042] The preferred embodiment is as shown in the figure Figures 2-3 As shown, the discharge end 312 of the feeding pipe 31 is screwed with a flow regulating member 33, the flow regulating member 33 is provided with a tapered groove 331 and a discharge groove 332 in communication, the tapered groove 331 is matched with the tapered head 323 of the screw 32 and forms a material passing channel 3311 therebetween, and the flow regulating member 33 adjusts the tightness of the screw connection with the feeding pipe 31 to adjust the size of the material passing channel 3311.

[0043] Before the first use of the conveying mechanism, according to the type and consistency of the sauce, the flow is corrected by the loose and tight flow adjusting piece 33, the appropriate material passing gap of the material passing channel 3311 is adjusted, and the purpose of further precise flow adjustment is achieved. In this embodiment, the preferred sauce includes various sauces with certain consistency (without particles) and various sauces with certain consistency including jam with conventional size particles, which can improve the conveying accuracy.

[0044] Preferred embodiment one, for various sauces with certain consistency without particles, the technical scheme of using the flow adjusting piece 33 to form a tapered material passing channel 3311 for flow adjustment can meet the accuracy requirement (the accuracy can reach 1-2g).

[0045] Preferred embodiment two, for various sauces with certain consistency with conventional size particles (such as passion fruit jam, strawberry jam, etc.), the technical scheme of using the thread groove 322 of the screw 32 with a groove depth of 2-3 times the particle diameter of the particle-containing sauce, and combining the flow adjusting piece 33 to form a tapered material passing channel 3311 for flow adjustment, can meet the conveying requirement and accuracy requirement (the accuracy can reach 1-2g).

[0046] Preferred implementation, as shown in Figure 4 The discharge end of the feeding round pipe 31 is connected with an electric regulating valve 5, and the electric regulating valve 5 has an output end 51 for discharging.

[0047] The implementation mainly aims at sauces with larger particles (such as grape jam, pineapple jam, etc.), and proposes a technical scheme of using an electric regulating valve 5 to control the output. In this way, smooth and accurate output of sauces with larger particles is ensured, and the problem of dripping is avoided due to self-suction at the output end 51 when the electric regulating valve 5 is closed.

[0048] Preferred embodiment three, for various sauces with certain consistency with larger particles, the technical scheme of using the thread groove 322 of the screw 32 with a groove depth of 2-3 times the particle diameter of the particle-containing sauce, and combining the discharge end electric regulating valve 5, can meet the conveying requirement and accuracy requirement (the accuracy can reach 1-2g).

[0049] Preferred implementation, as shown in Figure 3 The discharge end of the conveying mechanism is connected with a discharge nozzle 6, which is an elastic nozzle with a clamped closed outlet end 61. The material used for the elastic nozzle can be any suitable material for food, such as silicone material, forming a silicone discharge nozzle.

[0050] With the above scheme, when there is sauce passing through the discharge nozzle 6, the outlet end 61 is naturally opened to realize the discharge of sauce; when the discharge of sauce stops, the outlet end 61 of the discharge nozzle 6 restores the clamping closed state, thus avoiding the problem of possible dripping, ensuring the accuracy of conveying, and keeping the use clean and sanitary.

[0051] The discharge nozzle 6 further preferably has the following embodiments, as shown in Figures 5-6 As shown, the discharge nozzle 6 is provided with an elastic reinforcing member 62, which has a clamping portion 623 clamped on the opposite two side surfaces of the outlet end 61 of the discharge nozzle 6. The clamping portion 623 has a flat section 6231 and a fold line section 6232 corresponding to the opposite two side surfaces, respectively. The flat section 6231 and the corresponding side surface are in continuous contact, which can be continuous line contact or continuous surface contact. The fold line section 6232 and the corresponding side surface are in discontinuous contact, which can be one or any combination of at least two of intermittent point contact, intermittent line contact and intermittent surface contact.

[0052] With the above scheme, the special structure of the elastic reinforcing member 62, through the cooperation of the flat section 6231 and the fold line section 6232, on the one hand, the cooperation structure has sufficient elastic expansion range, which can maximize the weakening of the adverse effects of the clamping portion 623 on the opened outlet end 61 when the discharge nozzle 6 is in the discharging state. On the other hand, the cooperation structure brings a strengthening effect, which, when the outlet end 61 changes from discharging to stopping discharging, through the clamping and strengthening of the cooperation structure on the outlet end 61, not only avoids the problem of particles blocking at the outlet end 61, but also avoids the problem of dripping of the relatively dilute tail material at the outlet end 61. The discharge nozzle with the elastic reinforcing member 62 is applied to the preferred embodiment one and the preferred embodiment three, which brings more prominent beneficial effects.

[0053] In addition, in order to ensure the stable structure of the clamping portion 623 on the discharge nozzle 6, the elastic reinforcing member 62 further includes a fixed portion 621 and a connecting portion 622. The fixed portion 621 is arranged at a position away from the outlet end 61 of the discharge nozzle 6, and the clamping portion 623 is connected and arranged with the fixed portion 621 through the connecting portion 622.

[0054] The preferred embodiments are as shown in Figures 3-4 As shown, the inlet end of the discharge nozzle 6 is connected to a discharge elbow 34, which is mainly used to change the discharging direction of the conveying mechanism from horizontal to vertical downward, which is beneficial for the material receiving operation. In addition, in order to facilitate sanitary cleaning, the discharge elbow 34 is of a detachable structure.

[0055] The preferred embodiments are as shown in Figures 2-3As shown, the rear end of the screw rod 32 is provided with a bearing member 36, and the screw rod 32 is detachably assembled in the feeding pipe 31 through the bearing member 36, and the rear end of the screw rod 32 extends out of the feeding pipe 31 to form a transmission joint 324. In the embodiment, the bearing member 36 is provided with a plurality of groups to ensure the rotation of the screw rod 32.

[0056] The screw rod 32 is detachably assembled with the feeding pipe 31, and the screw rod 32 is detachably connected with the external related driving mechanism through the transmission joint 324. Thus, the effective cleaning effect of the conveying mechanism is realized, and during cleaning, the screw rod 32 only needs to be pulled out of the feeding pipe 31, and the whole mechanism can be completely cleaned in all directions and simply, and the problem of bacteria breeding caused by the retention of sauce in the pipe or the rod is avoided. After cleaning, the screw rod 32 only needs to be inserted into the feeding pipe 31, which is simple and convenient.

[0057] Further, the front side of the screw rod 32 corresponding to the bearing member 36 is provided with a sealing member 37. The sealing member 37 is provided to seal, so as to avoid the sauce in the feeding pipe 31 from entering the bearing member 36 or even overflowing out, and to ensure the stable, reliable and sanitary use of the whole machine structure and function. In addition, the bearing member 36 is preferably made of plastic bearing or ceramic bearing, so that the rusting of the bearing is well avoided, and the function use and service life are affected.

[0058] Further, the rear side of the screw rod 32 corresponding to the bearing member 36 is also provided with a snap ring 38 and a rear end cover 39, and the assembly and fixation of the snap ring 38 and the rear end cover 39 are beneficial to the stable and reliable structure and work of the bearing member 36.

[0059] In the preferred embodiment, the new conveying mechanism can also be provided with a screw rod driving mechanism 4 for driving the rotation of the screw rod 32. The screw rod driving mechanism 4 can have various embodiments, such as a servo motor or a speed reducer motor device, as long as it can drive the rotation of the screw rod 32.

[0060] The new conveying mechanism realizes the accurate conveying of sauce, and the sauce is not wasted by using the measured amount, and is clean and sanitary. The new conveying mechanism is not only suitable for the preparation of various milk tea drinks containing jam, but also can be applied to the quantitative addition and use of various seasoning sauces in Chinese and western food.
