Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a feeding device of a dried fruit packaging machine. Background Art

[0002] In the packaging process of dried fruits (such as red dates, walnuts, etc.), it is usually necessary to use a packaging device to measure and package the dried fruits to meet different market demands. At present, dried fruits are usually measured and packaged using a multi-head weigher (combination weigher) packaging equipment. This equipment pours the dried fruits into the material box through a vibrating guide plate, and then measures and puts them in by setting a weighing device in the material box.

[0003] In the prior art, users usually control the feeding speed of dried fruits by changing the vibration amplitude and vibration interval of the guide plate to avoid the situation of feeding too much at one time. However, when packing round or oval dried fruits such as walnuts or red dates, even if the user turns off the vibration equipment in time, due to the shape characteristics of such dried fruits, some dried fruits may continue to roll and fall into the material box under the action of inertia, thereby interfering with the precise measurement of the dried fruits and affecting the packaging efficiency and accuracy.

[0004] The above information disclosed in the background technology section is only used to enhance the understanding of the background technology of the technology described in this article. Therefore, the background technology may contain certain information that does not form the prior art known in this country to those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: In the prior art, users generally adjust the vibration amplitude and vibration interval of the guide plate to achieve precise control of the dried fruit feeding speed, aiming to avoid the problem of excessive feeding at one time. However, when packaging round or oval dried fruits such as walnuts and red dates, even if the operator quickly turns off the vibration equipment, due to the unique shape of these dried fruits, some dried fruits may continue to roll and fall into the feed bin due to inertia, thereby interfering with the precise measurement of the dried fruits and ultimately affecting the efficiency and accuracy of the packaging operation.

[0027] Therefore, in order to solve the problem that the existing packaging mechanism is difficult to accurately control the amount of material when packaging round dried fruits, and to achieve the function of improving the packaging and metering accuracy, the utility model discloses a dry fruit packaging machine feeding device, Figure 1-Figure 5 , including a packaging layer 1 and a lower hopper 6 arranged parallel to the bottom of the packaging layer 1, the packaging layer 1 includes a receiving tray 2, a primary screening box 4 and a secondary screening box 5 arranged in sequence from top to bottom, and a material guide plate 3 corresponding to the feeding port of the primary screening box 4 is provided at the edge of the receiving tray 2, wherein the primary screening box 4 and the secondary screening box 5 are both provided with a weighing sensor for measuring the weight of dried fruits, characterized in that the material guide plate 3 includes two oppositely arranged side walls and a material trough connected between the two side walls, wherein the tops of the two side walls are provided with a gantry 8, the gantry 8 is provided with a first telescopic column 11 on the side facing the material trough, and the first telescopic column 11 is provided with a baffle 10 on one end facing the material trough, and a plate slot 12 is opened on the surface of the material trough, and the baffle 10 is movably inserted into the plate slot 12, and the baffle 10 is made to perform reciprocating lifting and lowering motion in the plate slot 12 by the first telescopic column 11;

[0028] In this embodiment, the packaging layer 1 is used to receive the dried fruit raw materials, and then these dried fruits are introduced into the primary screening material box 4 through the guide plate 3, wherein the packaging layer 1 is provided with a rapping rod for vibrating the guide plate 3. In the process of the guide plate 3 pouring the dried fruits into the primary screening material box 4, the first telescopic column 11 can pull up the baffle 10 from the plate groove 12, and use the baffle 10 to block the dried fruits at the subsequent positions so that these dried fruits will remain in the material groove, thereby preventing excess dried fruits from continuing to roll and falling into the primary screening material box 4. When one feeding is completed, the first telescopic column 11 can reinsert the baffle 10 into the plate groove 12, so that the dried fruits at the subsequent positions can continue to move toward the primary screening material box 4;

[0029] In another embodiment, when the material guide plate 3 is about to start conveying dried fruits, the user can lift the baffle 10 through the first telescopic column 11. At this time, the space between the baffle 10 and the output end of the material guide plate 3 is the delivery area. Since the baffle 10 blocks the subsequent dried fruits, only the dried fruits in the delivery area can be conveyed to the primary screening material box 4. It can be seen that by adjusting the distance between the baffle 10 and the output end of the material guide plate 3, the size of the delivery area can be controlled, thereby making the delivery amount of dried fruits more accurate.

[0030] In this embodiment, the first telescopic column 11 and the second telescopic column 14 are both connected to an external driving member. The external driving member includes a motor or a cylinder, which will not be described in detail below.

[0031] In this embodiment, the gantry 8 can be made of stainless steel, which can improve the stability of the baffle 10.

[0032] In this embodiment, a plurality of elliptical through holes are provided on the edging wall. The provision of such through holes can increase the friction of the material guide plate 3, and when the material guide plate 3 stops vibrating, it helps to avoid the inertial rolling of the dried fruits.

[0033] Example 2: Based on Example 1, in order to facilitate the position adjustment of the baffle 10 on the guide plate 3, refer to Figure 2 and Figure 3 The present invention further includes a translation column 9 and a screw rod for moving the baffle 10. Specifically, a straight groove 7 extending along the length direction of the trough is opened on the top of the edge wall, and a translation column 9 inserted into the straight groove 7 is provided at the bottom of both ends of the gantry 8. The screw rod penetrating the translation column 9 is provided in the straight groove 7.

[0034] In this embodiment, the above-described structure allows the user to conveniently adjust the position of baffle 10 on guide plate 3 to accommodate the packaging needs of different types or sizes of dried fruit. To adjust the position of baffle 10, simply rotate the screw using an external drive device (such as a motor or hand crank). This rotation drives the translation column 9 along the length of the trough within the straight trough 7, thereby driving the gantry 8, its first telescopic column 11, and baffle 10 as a whole. This allows for flexible adjustment of the spacing between baffle 10 and the output end of guide plate 3, enabling precise control of the amount of dried fruit delivered.

[0035] Furthermore, the surface of the material trough is provided with a number of parallel and equidistantly distributed plate grooves 12. Through this arrangement, when the user needs to adjust the position of the baffle 10, the user can first open the first telescopic column 11 so that the baffle 10 can be completely lifted from the current plate groove 12, and then moved to the top of another plate groove 12 driven by the screw rod and the translation column 9, and then lowered the baffle 10 into the plate groove 12 through the first telescopic column 11 to complete the adjustment of the position of the baffle 10.

[0036] In this embodiment, in the initial state, in order to prevent the baffle 10 from loosening in the plate groove 12, limiting grooves 13 are provided on both sides of the baffle 10, and second telescopic columns 14 corresponding to the limiting grooves 13 are provided on the inner wall of the plate groove 12. Through this arrangement, when there is no need to adjust the position of the baffle 10, the second telescopic columns 14 can be fitted into the limiting grooves 13 on both sides of the baffle 10. Subsequently, when the first telescopic column 11 lifts the baffle 10, the second limiting columns 14 will abut against the inner wall of the bottom of the limiting groove 13, so as to prevent the baffle 10 from being completely pulled out of the plate groove 12 during normal use. At the same time, the second limiting columns 14 can play a certain clamping role on the baffle 10, which helps to reduce the situation where the baffle 10 becomes loose in the plate groove 12.

[0037] It should be noted that when the position of the baffle 10 needs to be adjusted, the user can first close the second telescopic column 14 to shrink the second telescopic column 14 so that the baffle 10 can be smoothly lifted completely from the plate slot 12.

[0038] Example 3: Based on Example 1, in order to further improve the accuracy of dried fruit packaging, refer to Figure 3 , the interior of the primary screening material box 4 and the secondary screening material box 5 are both provided with a dial plate 16, wherein the weighing sensor is arranged on the side of the dial plate 16 facing the feed inlet, and the primary screening material box 4 and the secondary screening material box 5 are both provided with a rotating shaft 17 for flipping the dial plate 16, and a driving member 15 for driving the rotating shaft 17, and the driving member 15 is connected to the weighing sensor;

[0039] In this embodiment, through the above structure, after the dried fruit raw materials enter the primary screening material box 4, these dried fruits will fall on the dial plate 16. At this time, the weighing sensor in the dial plate 16 will start working to measure the weight of these fallen dried fruits. When the weight reaches a preset threshold, the weighing sensor will transmit a signal to the driving member 15 to drive the rotating shaft 17 to rotate, thereby driving the dial plate 16 to flip. The flipped dial plate 16 will send the weighed dried fruits into the re-screening material box 5, and then the re-screening material box 5 will weigh these dried fruits again. Finally, the re-screening material box 5 can pour these dried fruits into the lower hopper 6 for the next packaging process.

[0040] In addition, it should be noted that the weighing sensor is also connected to the driving device of the vibrating rod, that is, when the weight of the dried fruit in the initial screening box 4 reaches a preset threshold, the weighing sensor can also turn off the vibrating rod to stop the guide plate 3 from vibrating and feeding.

[0041] In this embodiment, the driving member 15 can be a motor.

[0042] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0043] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
