Description

Technical Field

[0001] This invention relates to the field of spice conveying equipment technology, and specifically to a tubular spice conveyor. Background Technology

[0002] Spice pipeline conveying equipment is a key piece of equipment for the food, daily chemical, and pharmaceutical industries to achieve automated and continuous production of spice raw materials. Its core function is to accurately transport powdered, granular, or liquid spices from storage units to mixing, packaging, and other process stages through a closed pipeline system, replacing traditional manual handling or mechanical conveying methods. This equipment must meet the spice industry's requirements for conveying accuracy and hygiene and safety, and is an important infrastructure to ensure product quality stability and production efficiency.

[0003] Currently, mainstream powdered fragrance conveying equipment mainly includes two categories: mechanical conveying (such as screw conveyors and bucket elevators) and pneumatic conveying (such as positive pressure dilute phase and negative pressure dense phase). The advantages of mechanical conveying are its simple structure and low cost, making it suitable for short-distance, high-volume conveying scenarios; however, its disadvantages are significant: open design can easily lead to fragrance dust leakage, causing environmental pollution and raw material waste; pneumatic conveying uses airflow to drive the powder flow, which has the advantages of good sealing and long conveying distance, and is especially suitable for long-distance transmission of volatile fragrances; however, high-speed airflow can easily cause fragrance particles to break, affecting the consistency of product flavor, low gas-solid separation efficiency may cause pipeline blockage or fragrance residue, the system has high energy consumption, and it is sensitive to material humidity and particle size distribution, limiting its adaptability.

[0004] Therefore, a tubular spice conveyor is proposed. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a tubular spice conveyor that can effectively solve the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a tubular spice conveyor, including a conveying body for conveying powdered spices. The conveying body includes an interconnected equipment box and a conveying pipe. Multiple sets of dials for pushing the material are slidably installed inside the conveying pipe, and adjacent dials are connected by a connecting chain. A rotating component for driving the dials is rotatably installed inside the equipment box. The dial includes a first movable disc and a second movable disc, which are connected by an elastic sleeve. A fixed sleeve is installed on the first movable disc, and a rotating column that is slidably connected to the fixed sleeve is installed on the second movable disc. The rotating column is provided with a guide groove, and the fixed sleeve is provided with a guide post that cooperates with the guide groove. The guide groove is used to guide and limit the distance between the first movable disc and the second movable disc. A spring is provided between the fixed sleeve and the rotating column.

[0007] According to some embodiments of the present invention, a drive motor is provided outside the equipment box, and the drive shaft of the drive motor is connected to a rotating component. The rotating component is provided with multiple sets of dial slots and a chain slot.

[0008] According to some embodiments of the present invention, the dial groove is V-shaped, and the opening of the dial groove faces the side of the rotating component away from the axis.

[0009] According to some embodiments of the present invention, the guide groove is composed of multiple sets of a segments and multiple sets of b segments forming a closed loop, the number of a segments and b segments is the same, and the distance between the turning point of the a segment and the second movable disk is greater than the distance between the turning point of the b segment and the second movable disk.

[0010] According to some embodiments of the present invention, the rotating column is provided with multiple sets of guide teeth II on the side away from the movable disk II, and the fixed sleeve is provided with multiple sets of guide teeth I. The guide teeth I are used to guide the rotating column to rotate and transfer the guide column from section a in the guide groove to section b.

[0011] According to some embodiments of the present invention, the connection points between the fixed sleeve and the rotating column and the connecting chain are all rotatable connections.

[0012] According to some embodiments of the present invention, it further includes a feeding assembly and a discharging assembly, which are disposed on the conveying pipe, and multiple discharging assemblies can be provided according to actual conditions.

[0013] According to some embodiments of the present invention, the number of guide posts is multiple sets arranged in a circular array on the fixed sleeve, and the number of guide posts corresponds to the number of segments a on the guide groove.

[0014] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By squeezing the movable discs 1 and 2 on the dial plate through the dial plate groove, the distance between the movable discs 1 and 2 is changed, thereby changing the state of the movable discs 1 and 2 on the elastic sleeve. When the movable discs 1 and 2 squeeze the elastic sleeve, the elastic sleeve deforms and sticks to the inner wall of the conveying pipe, so as to fully convey the powdery material. When the movable discs 1 and 2 stretch the elastic sleeve, the squeezing of the elastic sleeve is canceled, the elastic sleeve is separated from the inner wall of the conveying pipe, and the frictional resistance is reduced. Second, by driving the rotating parts inside the equipment box with a drive motor, and cooperating with multiple sets of dials and multiple sets of connecting chains to make the material feeding components move continuously in the conveying pipe, the material is conveyed in a sealed manner in the pipe, which effectively prevents the dust from escaping during the conveying of powdery materials, avoids the internal contamination of the conveying, keeps the powdery materials clean during the conveying, and reduces the hazards of dust.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] See attached document Figure 1-8A tubular spice conveyor includes a conveying body 1 for conveying powdered spices. The conveying body 1 includes an interconnected equipment box 11 and conveying pipes 12. Two sets of conveying pipes 12 are located on opposite sides of the equipment box 11. Similarly, the equipment box 11 also has two sets of conveying pipes 12 tangential to the conveying pipes 12. One conveying pipe 12 conveys the material to the discharge point, while the other conveying pipe 12 prevents the dials 14 from being contaminated during their return stroke, making it a complete and enclosed conveying channel. This prevents the generation of large amounts of dust during conveying and also effectively avoids contamination of the conveying channel, maintaining a clean conveying environment. Multiple sets of dials 14 for pushing the material are slidably installed inside the conveying pipe 12, and adjacent dials 14 are connected by a connecting chain 15. A rotating component 13 for driving the dials 14 is rotatably installed inside the equipment box 11. The rotation of the rotating component 13 moves the dials 14 within the equipment box 11, coordinating with the connecting chain 15 and multiple... The set of dial 14 realizes the continuous conveying of materials in the equipment box 11. The equipment box 11 is equipped with a drive motor 16, and the drive shaft of the drive motor 16 is connected to the rotating part 13. When the drive motor 16 is energized and rotates, it drives the rotating part 13 to rotate, thereby providing power for the movement of the dial 14 in the equipment box 11. The connecting chain 15 is composed of multiple chain segments, which can assist the dial 14 to move better in the equipment box 11, and can also adapt to various bends to increase the wider range of application scenarios. It also includes a feeding component 2 and a discharging component 3, which are set on the conveying pipe 12. Multiple discharging components 3 can be set according to the actual situation. The feeding component 2 adds materials into the equipment and enters the equipment box 11, and works with the connecting chain 15 and the dial 14 to continuously convey the materials. At the same time, the discharging component 3 discharges the materials to a designated location. Multiple sets of discharging components 3 can be set to meet the scenario of multi-point material discharge.

[0020] In the above technical solution, the rotating part 13 inside the equipment box 11 is driven by the drive motor 16, and the material feeding component is connected in series with multiple sets of dials 14 and multiple sets of connecting chains 15 to realize the continuous movement of the dials 14 in the conveying pipe 12, thereby sealing and conveying the material in the pipeline, effectively preventing the powdery material from escaping dust during conveying, avoiding internal contamination, keeping the powdery material clean during conveying, and reducing dust hazards. By setting multiple sets of discharge components 3, multi-point material feeding is realized. Through the cooperation of multiple sets of connecting chains 15 and dials 14, the pipeline can adapt to multiple bends when conveying materials, and has a wide range of applications.

[0021] In addition, the dial 14 includes a first movable disc 141 and a second movable disc 142, which are connected by an elastic sleeve 146. The first movable disc 141 and the second movable disc 142 are located on opposite sides of the elastic sleeve 146, which is made of rubber. When the first movable disc 141 and the second movable disc 142 approach each other, the elastic sleeve 146 is compressed and bulges; conversely, it is pulled to align with the first movable disc 141 and the second movable disc 142. A fixed sleeve 143 is installed on the first movable disc 141, and a fixed sleeve 143 is installed on the second movable disc 142. A rotating column 144 is installed and slidably connected to a fixed sleeve 143. A spring 145 is provided between the fixed sleeve 143 and the rotating column 144. A guide groove 1442 is provided on the rotating column 144, and a guide post 1432 that cooperates with the guide groove 1442 is provided on the fixed sleeve 143. The guide groove 1442 is used to guide and limit the distance between the first movable disk 141 and the second movable disk 142. When the fixed sleeve 143 and the rotating column 144 approach each other, they will drive the first movable disk 141 and the second movable disk 142 to approach each other. At this time, the guide post 1432 will slide in the guide groove 1442, thereby moving the first movable disk 141 and the second movable disk 142 closer together. The positions of movable disc 141 and movable disc 142 are restricted. After pressing movable disc 141 and movable disc 142 once, and then releasing the press, the distance between movable disc 141 and movable disc 142 is L. After pressing movable disc 141 and movable disc 142 twice, and then releasing the press, the distance between movable disc 141 and movable disc 142 is M, and L ≠ M (L > M or L < M). The rotating component 13 is provided with multiple sets of dial grooves 131, and the rotating component 13 is provided with chain grooves 132. The dial grooves 131 are V-shaped and open. With the opening facing the side of the rotating part 13 away from the axis, after the dial 14 enters the dial groove 131 as a whole, when the dial 14 moves to the farthest position between the two sets of equipment boxes 11, the dial 14 will move towards the axis of the rotating part 13 under the pull of the connecting chain 15. In conjunction with the special shape of the dial groove 131, it will squeeze the first movable disk 141 and the second movable disk 142, so that the first movable disk 141 and the second movable disk 142 will move closer to each other, and finally realize that the guide post 1432 slides in the guide groove 1442 to change the distance limit between the first movable disk 141 and the second movable disk 142. Specifically, the guide groove 1442 consists of multiple sets of a segments and multiple sets of b segments forming a closed loop. The number of a segments and b segments is the same, and the distance between the turning point of a segment and the second movable disk 142 is greater than the distance between the turning point of a segment and the second movable disk 142. After the first movable disk 141 and the second movable disk 142 are squeezed by the rotating component 13, the rotating column 144 extends into the fixed sleeve 143. At this time, the guide column 1432 slides in the guide groove 1442 and moves from segment a to segment b. After the compression of movable disc 141 and movable disc 2 142 is released, the guide post 1432 will move from the bend at section a to the bend at section b under the guidance of the guide groove 1442, thereby limiting the distance between movable disc 141 and movable disc 2 142. When the distance between movable disc 141 and movable disc 2 142 changes, the compression or stretching of the elastic sleeve 146 is changed, and the state of the elastic sleeve 146 is switched to achieve the degree of fit with the inner wall of the conveying pipe 12.

[0022] Furthermore, the rotating column 144 is provided with multiple sets of guide teeth 1441 on the side away from the movable disk 142, and the fixed sleeve 143 is provided with multiple sets of guide teeth 1431. The guide teeth 1431 are used to guide the rotating column 144 to rotate and transfer the guide column 1432 from section a in the guide groove 1442 to section b, preventing the guide column 1432 from moving back from the initial section. That is, with the cooperation of the guide teeth 1431 and the guide teeth 1441, the guide column 1432 can better realize the transfer from section a in the guide groove 1442 to section b.

[0023] Furthermore, the connection points between the fixed sleeve 143 and the rotating column 144 and the connecting chain 15 are all rotatable connections. Conversely, the rotation of the dial 14 when the state changes affects the conveying. The number of guide columns 1432 is multiple sets arranged in a ring array on the fixed sleeve 143, and the number of guide columns 1432 corresponds to the number of segments a on the guide groove 1442.

[0024] In the above technical solution, when the connecting chain 15 pulls the dial 14 to move within the conveying pipe 12, as the dial 14 moves to the rotating member 13 on one side, and as the dial 14 moves with the rotating member 13 within the dial groove 131, when the dial 14 moves to the furthest point between the two sets of rotating members 13, the dial 14 moves towards the axis of the rotating member 13 under the pull of the connecting chain 15, thereby cooperating with the special shape of the dial groove 131 to press the movable disc 141 and the movable disc 142. As they approach each other, the rotating column 144 inserts into the fixed sleeve 143. With the cooperation of the guide column 1432 and the guide groove 1442, and guided by the first guide tooth 1431 and the second guide tooth 1441, the guide column 1432 is transferred from section a to section b in the guide groove 1442. When the guide column 1432 moves to the turning point of section b, the distance between the first movable disc 141 and the second movable disc 142 increases under the pull of the connecting chain 15. At this time, the elasticity of the first movable disc 141 and the second movable disc 142 increases. The sleeve 146 is used to prevent the elastic sleeve 146 from contacting the inner wall of the conveying pipe 12 during the return stroke. Conversely, when the dial 14 starts conveying material after passing the rotating member 13, the dial 14 moves towards the axis of the rotating member 13 under the pull of the connecting chain 15. This, combined with the special shape of the dial groove 131, further squeezes the movable disc 141 and the movable disc 142 closer together. At this time, the rotating column 144 is inserted into the fixed sleeve 143. The cooperation between the guide column 1432 and the guide groove 1442, as well as the guide... Guided by guide teeth 1431 and 1441, guide post 1432 is transferred from section b to section a in guide groove 1442. When guide post 1432 moves to the turning point of section a, the distance between movable disc 141 and movable disc 142 decreases under the pull of connecting chain 15. At this time, movable disc 141 and movable disc 142 squeeze elastic sleeve 146, so that elastic sleeve 146 contacts the inner wall of conveying pipe 12 during conveying, and fully conveys powdery material.

[0025] Working principle: During operation, the drive motor 16 drives the rotating component 13 to rotate, which, in conjunction with the connecting chain 15, drives the dial 14 to move within the conveying pipe 12, thereby conveying the material in the feeding assembly 2 to the discharge assembly 3 for discharge. Figure 1For example, when the dial 14 moves from the end without the drive motor 16 to the end with the drive motor 16, the movable disc 141 and movable disc 142 on the dial 14 are squeezed by the dial groove 131, and the distance between the movable disc 141 and movable disc 142 becomes smaller, thereby squeezing the elastic sleeve 146 to deform and adhere to the inner wall of the conveying pipe 12, so as to fully convey the powdered material. When the dial 14 moves from the end with the drive motor 16 to the end without the drive motor 16, that is, during the return stroke, the movable disc 141 and movable disc 142 on the dial 14 are squeezed by the dial groove 131, and the distance between the movable disc 141 and movable disc 142 becomes larger, thereby canceling the squeezing of the elastic sleeve 146. At this time, the elastic sleeve 146 does not adhere to the inner wall of the conveying pipe 12, reducing frictional resistance.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
