Description

Technical Field

[0001] This utility model relates to the field of material supply equipment technology, specifically to an automatic feeding device capable of quantitative output. Background Technology

[0002] In the current tea beverage production industry, tea production volume is showing a continuous upward trend. However, the entire production process, especially the crucial tea brewing step, still relies heavily on traditional manual methods. This traditional production mode not only severely restricts the improvement of production efficiency, but also faces difficulties in accurately achieving standards in terms of tea supply and weight control, making it difficult to meet the high requirements of precision and efficiency in modern tea beverage production.

[0003] Currently, some automatic tea dispensing devices have appeared on the market. These devices weigh the tea leaves to obtain the required weight, thus achieving a certain degree of quantitative dispensing. This method of dispensing loose tea leaves by weighing plays a role in certain specific situations. However, in many tea-making scenarios, it is often necessary to use pre-packaged tea bags for brewing. In the actual tea-brewing process, a specific number of tea bags must be used to ensure the consistency of the tea's quality and flavor. However, the existing loose weighing dispensing method is clearly not suitable for the feeding needs of tea bags: when using a weighing dispensing device to achieve quantitative dispensing of tea bags, additional complex operations and structural modifications are required on top of the existing device. The presence of the weighing mechanism leads to structural complexity and cumbersome operation. From the perspective of work efficiency, this complexity makes the feeding process cumbersome and time-consuming, greatly limiting the improvement of work efficiency and making it difficult to meet the urgent needs of the tea-making industry for fast, efficient, and accurate dispensing. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide an automatic feeding device that can quantitatively output materials, which can store multiple portions of materials and quantitatively output materials from one or more storage mechanisms as needed, with a simple and convenient structure and operation.

[0005] To achieve the above objectives, this utility model provides an automatic feeding device capable of quantitative output, comprising a conveyor belt mechanism and a drive mechanism. The conveyor belt mechanism includes two parallel belt shafts and a conveyor belt with its two ends respectively mounted on the two belt shafts. The drive mechanism is connected to the conveyor belt mechanism and can drive the conveyor belt to move. It also includes a placement mechanism. The plane in which the center lines of the two belt shafts of the conveyor belt mechanism are located is the conveying positioning plane, and the angle between the conveying positioning plane and the vertical plane is 0 to 60°. The angle between the belt shafts and the horizontal plane is 0 to 30°. There are multiple placement mechanisms, which are fixedly arranged on the conveyor belt at intervals. Each placement mechanism has a placement structure for placing materials on opposite sides along the direction of movement of the conveyor belt.

[0006] Furthermore, the belt shaft of the conveyor belt mechanism is horizontally positioned.

[0007] Furthermore, the angle between the conveying positioning plane and the vertical plane is 0°.

[0008] Furthermore, the placement structure of the placement mechanism includes a placement plane, which is parallel to the belt shaft, and the conveyor belt is perpendicular to the placement planes on both sides of the placement mechanism when it is in a flattened state.

[0009] Furthermore, the placement mechanism is arranged at equal intervals along the extension direction of the conveyor belt.

[0010] Furthermore, the conveyor belt includes an ascending section and a descending section on both sides. When the conveyor belt moves, the placement mechanism on the ascending section moves upward and the placement mechanism on the descending section moves downward. A pre-discharge detection station is provided on the lower side of the descending section. It also includes a discharge detection component, which includes a pre-discharge detector that can detect the material on the placement mechanism located at the pre-discharge detection station.

[0011] Furthermore, a post-discharge detection station is provided below the bottom of the conveyor belt, and the post-discharge detection component includes a post-discharge detector, which can detect the material located on the placement mechanism at the post-discharge detection station.

[0012] Furthermore, the conveyor belt includes an ascending section and a descending section on each side. When the conveyor belt moves, the placement mechanism located on the ascending section moves upward and the placement mechanism located on the descending section moves downward. The automatic feeding device also includes a position calibration detector. When the conveyor belt moves to the point where a placement mechanism is detected by the position calibration detector, the number of placement mechanisms on the ascending section and the descending section is the largest.

[0013] Furthermore, it also includes a support frame and a lifting and adjusting mechanism mounted on the support frame. The conveyor belt mechanism is mounted on the support frame, and at least one belt shaft is mounted on the lifting and adjusting mechanism, which can adjust the height position of the belt shaft and stabilize it.

[0014] Furthermore, the lifting and adjusting mechanism includes a slider, a lifting and adjusting block, and a locking assembly. The slider and the lifting and adjusting block are both mounted on the support frame and can move up and down in a direction parallel to the conveying positioning plane and perpendicular to the belt shaft. The locking assembly can lock and fix the lifting and adjusting block on the support frame. The two ends of the belt shaft are respectively mounted on the slider and the lifting and adjusting block.

[0015] Furthermore, it also includes a protective housing, in which the conveyor belt mechanism and the storage mechanism are both located.

[0016] Furthermore, it also includes a hatch panel located below the bottom of the conveyor belt mechanism, and a hatch opening and closing mechanism that drives the hatch panel to flip up and down.

[0017] As described above, the automatic feeding device of this utility model has the following beneficial effects:

[0018] 1. It can put multiple portions of materials into multiple storage mechanisms according to usage needs, and then automatically output the materials from one or more storage mechanisms according to output needs, realizing automatic quantitative feeding. The automatic feeding device has a simple structure and is easy to operate and control.

[0019] 2. The discharge detection component can detect whether there is material on the placement mechanism and whether the material slides out smoothly, effectively avoiding empty output and accurately outputting the required material.

[0020] 3. Use a position calibration detector to calibrate the position of the storage mechanism when the machine stops, ensuring that as many storage mechanisms as possible can be used to store materials, thereby maximizing material storage.

[0021] 4. By setting up door panels and door opening and closing mechanisms, the problem of materials falling incorrectly due to malfunctions of the conveyor belt mechanism can be avoided, thus preventing incorrect material discharge. Attached Figure Description

[0055] See Figures 1 to 6 This invention provides an automatic feeding device capable of quantitative output, comprising a conveyor belt mechanism 1 and a drive mechanism 3. The conveyor belt mechanism 1 includes two parallel belt shafts 12 and a conveyor belt 11 with its two ends respectively mounted on the two belt shafts 12. The two belt shafts 12 support the conveyor belt 11 and can drive the conveyor belt 11. The conveyor belt mechanism 1 can specifically adopt an existing design structure. The drive mechanism 3 is connected to the conveyor belt mechanism 1 and can drive the conveyor belt 11 to move. The automatic feeding device of this invention also includes a placement mechanism 2. The plane where the center lines of the two belt shafts 12 of the conveyor belt mechanism 1 lie is the conveying positioning plane 14. The angle between the conveying positioning plane 14 and the vertical plane is 0 to 60°, and the angle between the belt shafts 12 and the horizontal plane is 0 to 30°. Multiple placement mechanisms 2 are fixedly arranged on the conveyor belt 11 at intervals. Placement structures 21 for placing materials are provided on opposite sides of the placement mechanism 2 along the direction of movement of the conveyor belt 11.

[0056] The main working principle of the automatic feeding device involved in this utility model is as follows: When using the automatic feeding device, see... Figure 4The section of the conveyor belt 11 located between the two belt shafts 12 is taut and flat. When the belt shafts 12 of the conveyor belt mechanism 1 rotate, they drive the conveyor belt 11 to move. One side of the taut and flat section of the conveyor belt 11 moves upward; for ease of explanation, this side is referred to as the left side, and the upward-moving taut and flat section is referred to as the rising section 111. Correspondingly, the other side (i.e., the right side) moves downward, and the downward-moving taut and flat section is referred to as the falling section 112. Materials can be placed on the upward-facing placement structures 21 of the placement mechanisms 2 located on the rising section 111 and the falling section 112. The placement structure 21 can be a surface capable of supporting materials (a flat surface or a concave curved surface, etc.), or it can be a container capable of accommodating and preventing materials from slipping out, etc. At this time, the amount of material placed on each placement mechanism 2 can be the same or different. Therefore, before feeding, the automatic feeding device can store multiple portions of material for subsequent continuous feeding. When material needs to be output, the control drive mechanism 3 is activated, driving the conveyor belt 11 to move. (See below) Figure 4 When the placement mechanism 2 on the conveyor belt 11 moves from the descending section 112 to the bottom of the conveyor belt 11, that is, when it is located in the arc-shaped section where the conveyor belt 11 is in contact with the lower belt shaft 12, the placement mechanism 2 will gradually rotate 180 degrees around the lower belt shaft 12 and reach the ascending section 111. The placement structure 21, which was originally facing upward and containing material, becomes facing downward during this process, and the material in the placement structure 21 will slide down. This range of movement is recorded as the sliding discharge area 13, that is, the sliding discharge area 13 is located below the descending section 112, and the placement mechanism 2 rotates 180 degrees when passing through the sliding discharge area 13, realizing the downward output of the material. The empty placement mechanism 2 crosses the arc-shaped section at the bottom of the conveyor belt 11 and then moves to the left side, that is, it becomes the placement mechanism 2 on the ascending section 111. The rising section 111 of the conveyor belt 11 drives the placement mechanism 2 on it to move upward. Then, when the placement mechanism 2 crosses the arc-shaped section of the upper part of the conveyor belt 11 that is in contact with the upper belt shaft 12, the placement mechanism 2 will rotate 180 degrees. The material in the originally upward-facing placement structure 21 will move closer to the conveyor belt 11 during the rotation of the placement mechanism 2, and can then fall into another upward-facing placement structure 21 located on the falling section 112. That is, the material will be transferred from one placement mechanism 2 to another. Therefore, during the continuous movement of the conveyor belt 11, the material on one placement mechanism 2 can be output at a time. Thus, according to the required amount of material, the movement of the conveyor belt 11 can be controlled to a specified stroke, so that N placement mechanisms 2 pass through the sliding discharge area 13, thereby outputting the material on N placement mechanisms 2.

[0057] The automatic feeding device of this utility model can be used for quantitatively packaged materials such as tea bags, and can also be used for other quantitative materials. According to the needs of use, multiple portions of materials can be placed and stored on multiple storage mechanisms 2. The quantity of materials on each storage mechanism 2 can be one or more portions. Then, according to the output needs, the materials on one or more storage mechanisms 2 can be automatically output to achieve automatic quantitative feeding.

[0058] See Figures 1 to 6 The present invention will be further described below with reference to a specific embodiment:

[0059] In this embodiment, see Figure 1 and Figure 4 As a preferred design, the belt shaft 12 of the conveyor belt mechanism 1 is horizontally positioned, meaning the angle between the belt shaft 12 and the horizontal plane is 0°. The angle between the conveying positioning plane 14 and the vertical plane in the conveyor belt mechanism is 0°. The rising section 111 and the descending section 112 are located on both sides of the conveying positioning plane 14 and are parallel to the conveying positioning plane 14. At this time, the rising section 111 moves vertically upward, and the descending section 112 moves vertically downward. This can better drive the movement of the placement mechanism 2 and complete the material transfer and tilting actions. Furthermore, the placement mechanism 2 can be a flat plate with flat surfaces on both sides, which can hold materials. That is, the placement structures 21 on both sides are mainly composed of a placement plane, which is parallel to the belt shaft 12. When the conveyor belt 11 is in a flattened state, it is perpendicular to the placement plane on both sides of the placement mechanism 2, which facilitates stable placement of materials such as tea bags. At this time, no enclosure is required around the placement plane, and the structure of the placement structure 21 is simple.

[0060] In other embodiments, the belt shaft 12 of the conveyor belt mechanism 1 can also be inclined to a certain extent. When the inclination angle with the horizontal plane is within 30°, the corresponding function can also be achieved. Its working principle is basically the same as when the belt shaft 12 is horizontal. In this case, the linear movement direction of the rising section 111 and the falling section 112 of the conveyor belt 11 is inclined. Similarly, the conveying positioning plane 14 where the center lines of the two belt shafts 12 are located can also be inclined to a certain extent. When the angle between the plane and the vertical plane is within 60°, the corresponding function can also be achieved. In this case, the linear movement direction of the rising section 111 and the falling section 112 of the conveyor belt 11 is inclined, and its working principle is basically the same as when the belt shaft 12 is horizontal. When the rising section 111 and the falling section 112 are inclined, the storage structure 21 of the storage mechanism 2 on the rising section 111 and the falling section 112 can also be inclined at a certain angle. At this time, the storage structure 21 can be a box structure. For example, the storage structure 21 includes a storage plane and a ring of barriers around the storage plane to form a box-shaped structure, which can prevent the materials inside from slipping out due to the inclination of the storage structure 21.

[0061] In this embodiment, see Figure 1 and Figure 4 As a preferred design, the placement mechanisms 2 are evenly spaced along the extension direction of the conveyor belt 11. The specific number of placement mechanisms 2 can be set according to actual needs, and the spacing L between adjacent placement mechanisms 2 is also set according to the material conditions. All placement mechanisms 2 are arranged in a circle along the extension direction of the annular conveyor belt 11. Therefore, when controlling the output of materials, each movement L of the conveyor belt 11 can complete the output of materials from one placement mechanism 2. When it is necessary to output materials from N placement mechanisms 2, the movement stroke of the conveyor belt 11 is controlled to be N*L. Preferably, a control mechanism is also included, which is connected to the drive mechanism 3 for control. The control mechanism controls the conveyor belt 11 to automatically move a specific stroke each time.

[0062] In this embodiment, see Figure 1 , Figure 4 and Figure 6As a preferred design, a pre-discharge detection station is provided on the lower side of the descending section 112. When the descending section 112 drives the placement mechanism 2 downward, it will pass through the pre-discharge detection station and then enter the sliding discharge area 13 located below the descending section 112. It also includes a discharge detection component 7, which includes a pre-discharge detector 72 located next to the pre-discharge detection station. The pre-discharge detector 72 can detect the material on the placement mechanism 2 located at the pre-discharge detection station. Since some placement mechanisms 2 may not have any material placed on them, i.e., they are empty placement mechanisms 2, before controlling a placement mechanism 2 to move through the sliding discharge area 13, the pre-discharge detector 72 first detects whether there is material on the placement mechanism 2 and feeds the signal back to the control mechanism. If material is detected, the placement mechanism 2 is recorded as a valid output; if no material is detected, the placement mechanism 2 is recorded as an empty output. The control mechanism then controls the conveyor belt 11 to continue moving for a stroke L to output material from the next placement mechanism 2. Furthermore, a post-discharge detection station is provided below the bottom of the conveyor belt 11. The post-discharge detection station is located at the sliding discharge area 13. The discharge detection component 7 includes a post-discharge detector 71, which can be located behind the post-discharge detection station. The post-discharge detector 71 can detect the material on the placement mechanism 2 located at the post-discharge detection station and feed the signal back to the control mechanism, thereby ensuring that the material on the placement mechanism 2 slides down smoothly and is output. This monitors whether there is a problem of unsuccessful discharge due to material sticking to the placement mechanism 2 or getting stuck at the discharge point. Both the pre-discharge detector 72 and the post-discharge detector 71 can be photoelectric detectors such as infrared. When the material blocks its detection light, it can be detected by the pre-discharge detector 72 and the post-discharge detector 71. The pre-discharge detector 72 and the post-discharge detector 71 can specifically use existing mature detection products, and their working principles will not be detailed here. The pre-discharge detector 72 and the post-discharge detector 71 can also adopt the visual detection principle. By taking pictures of the placement structure 21, it can be determined whether there is material inside. The visual detection principle can also adopt the existing design, and its working principle will not be described in detail.

[0063] In this embodiment, see Figure 1 , Figure 4 and Figure 6As a preferred design, a position calibration detector 6 is also included to calibrate the position of the placement mechanism 2 when the conveyor belt mechanism 1 stops. When materials need to be added to the automatic feeding device, the conveyor belt mechanism 1 is first controlled to move, driving the placement mechanism 2 to move, so that one placement mechanism 2 can be detected by the position calibration detector 6. The conveyor belt mechanism 1 then stops, minimizing the number of placement mechanisms 2 on the upper and lower arc sections of the conveyor belt 11, and maximizing the number of placement mechanisms 2 on the rising section 111 and the falling section 112, so that as many placement mechanisms 2 as possible are in a horizontal position, thus facilitating the addition of more materials. The specific position of the position calibration detector 6 is determined based on the spacing L of the placement mechanisms 2 and the diameter of the output shaft.

[0064] In this embodiment, see Figure 1 , Figure 2 and Figure 4 As a preferred design, the system also includes a support frame 4 and a lifting adjustment mechanism 5 mounted on the support frame 4. The conveyor belt mechanism 1 is mounted on the support frame 4, and at least one belt shaft 12 is mounted on the lifting adjustment mechanism 5. The lifting adjustment mechanism 5 can move and stabilize the height position of the belt shaft 12. The height of the belt shaft 12 is adjusted to ensure that the conveyor belt 11 remains taut. In this embodiment, specifically, the upper belt shaft 12 is rotatably mounted on the support frame 4, its height position remains fixed, and it is connected to the drive mechanism 3 as the drive shaft for driving the conveyor belt 11. The lower belt shaft 12 is a driven shaft, mounted on the lifting adjustment mechanism 5, and its vertical position can be adjusted.

[0065] In this embodiment, see Figure 1 , Figure 2 and Figure 4As a preferred design, the lifting adjustment mechanism 5 includes a slider 52, a lifting adjustment block 51, and a locking assembly. Both the slider 52 and the lifting adjustment block 51 are mounted on the support frame 4 and can move up and down along a direction parallel to the conveying positioning plane 14 and perpendicular to the belt shaft 12 (i.e., vertical in this embodiment). The locking assembly can lock the lifting adjustment block 51 onto the support frame 4. The two ends of the belt shaft 12 are respectively mounted on the slider 52 and the lifting adjustment block 51. The lifting adjustment block 51 has a vertically extending slotted hole 511. The locking assembly includes a locking bolt (not shown in the figures) that passes through the slotted hole 511 and is screwed onto the support frame 4. When height adjustment is required, the locking bolt is loosened, thus releasing the locking of the lifting adjustment block 51. The lifting adjustment block 51 can then be moved up and down, and the locking bolt slides up and down in the slotted hole 511. The lifting adjustment block 51 drives the belt shaft 12 to move up and down, and the slider 52 also slides up and down. After height adjustment, the locking bolt is tightened to fix the lifting adjustment block 51 onto the support frame 4. The lifting and adjusting mechanism 5 can easily adjust and stabilize the position of the shaft 12. In other embodiments, the locking component can also adopt other existing suitable structures, such as a circular hole + spring positioning pin. In addition, the lifting and adjusting mechanism 5 as a whole can also adopt other existing suitable structures.

[0066] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the drive mechanism 3 includes a motor, which is directly or via an intermediate transmission structure connected to the upper belt shaft 12 of the conveyor belt mechanism 1. This allows for precise control of the rotation angle of the belt shaft 12 and the travel of the conveyor belt 11. In this embodiment, the conveyor belt mechanism 1 can adopt a conventional structure, with two belt shafts 12 supporting the conveyor belt 11. The upper belt shaft 12 serves as the drive shaft for driving the conveyor belt 11. The lower belt shaft 12 can rotate, acting as a driven shaft, or it can remain stationary. Depending on the axial length, the belt shaft 12 may be referred to as a pulley in some cases; the two are essentially the same.

[0067] In this embodiment, see Figure 5 and Figure 6Furthermore, the hatch opening and closing mechanism 9 includes two position detectors 91 for detecting the position of the hatch panel 8. One position detector 91 detects the hatch panel 8 when it rotates to the closed position, and the other position detector 91 detects it when it rotates to the open position, thus ensuring automatic detection and control of the hatch panel 8's position. The position detectors 91 can be conventional contact or non-release position switches, and can directly detect the hatch panel 8 or detect a detection piece fixed to the hatch panel 8. When no material is being fed, the hatch panel 8 is rotated to the closed position based on the signal from the position detector 91. When material feeding is required, the hatch panel 8 is first controlled to rotate, and the rotation stops when it reaches the open position based on the signal from the position detector 91. Then, the drive mechanism 3 is activated to drive the conveyor belt mechanism 1.

[0068] 1. It can put multiple portions of materials into multiple storage mechanisms 2 according to the needs of use, and then automatically output the materials from one or more storage mechanisms 2 according to the output needs, so as to realize automatic quantitative feeding. The automatic feeding device has a simple structure and convenient operation control.

[0069] 2. The discharge detection component 7 can detect whether there is material on the placement mechanism 2 and whether the material slides out smoothly, effectively avoiding empty output and accurately outputting the required material.

[0070] 3. The position of the storage mechanism 2 is calibrated by the position calibration detector 6 when the control stops, so as to ensure that as many materials as possible can be placed on the storage mechanism 2, thereby maximizing the storage of materials.

[0071] 4. By setting the door plate 8 and the door opening and closing mechanism 9, the problem of material falling incorrectly due to the malfunction of the conveyor belt mechanism 1 can be avoided, thereby preventing incorrect material discharge.

[0072] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0073] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
