Description

Technical Field

[0001] This utility model relates to an automatic spoon-feeding mechanism, belonging to the technical field of food packaging equipment. Background Technology

[0002] In the food packaging process, food is first sealed in a packaging bowl, then a spoon is added to the bowl, and finally a lid is added for sealing. Some existing spoon-adding mechanisms can only transport the spoon to the packaging line and cannot automate the process. Manual placement of the spoon onto the packaging bowl is required, followed by adding the lid and sealing it. This method is time-consuming, labor-intensive, and inefficient. Furthermore, while some spoon-adding mechanisms can automatically add the spoon to the packaging bowl, their accuracy is poor, often resulting in the spoon extending beyond the packaging bowl, affecting subsequent lid-adding and sealing operations. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic spoon-adding mechanism that can not only automate spoon-adding but also accurately add the spoon to the packaging bowl, thus avoiding interference with subsequent lid-adding operations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic spoon-feeding mechanism includes a worktable, a bowl conveying assembly, and a spoon conveying assembly. The bowl conveying assembly is located on the upper side of the worktable. The bowl conveying assembly includes a first mounting shell fixedly connected to the upper side of the worktable. A first rotating shaft is rotatably connected to each of the two ends inside the first mounting shell. A first motor is fixedly mounted on the front side of the first mounting shell and connected to the first rotating shaft on that side. A tensioned first conveyor belt is sleeved on the outer side of the first rotating shaft. A set of evenly distributed positioning grooves is provided on the first conveyor belt, and a set of evenly distributed detection grooves is provided on the front side of the first conveyor belt. The front of the first mounting shell... A mounting block is fixedly connected to the side of the bowl conveying assembly, and an infrared rangefinder is fixedly connected to the upper side of the mounting block. A spoon conveying assembly is provided on the rear side of the bowl conveying assembly. The spoon conveying assembly includes two support frames fixedly connected to the upper side of the worktable. A second mounting shell is fixedly connected to the front side of each support frame. A second rotating shaft is rotatably connected to the upper and lower ends of the inner side of the second mounting shell. A second motor is fixedly installed on the front side of the second mounting shell. The second motor is connected to the second rotating shaft on that side. A tensioned second conveyor belt is sleeved on the outer side of each of the second rotating shafts. A set of evenly distributed positioning plates is fixedly connected to the outer side of each of the second conveyor belts.

[0006] Preferably, both the positioning groove and the detection groove are cylindrical grooves, and the detection groove is located directly in front of the positioning groove.

[0007] Preferably, the mounting block is located at the middle position in the left-right direction of the first mounting shell, and the height of the infrared rangefinder probe is the same as the height of the detection groove located on the upper side.

[0008] Preferably, the two second conveyor belts are symmetrically distributed from left to right, and each second conveyor belt is located above the first conveyor belt, with a gap between the second conveyor belt and the first conveyor belt that allows the packaging bowl to pass through.

[0009] Preferably, the positioning plates are all bent soft rubber plates, and the two sets of positioning plates are symmetrically distributed from left to right, with the two sets of positioning plates contacting and aligning at their closest ends.

[0010] Compared with existing technologies, this technical solution has the following beneficial effects:

[0011] In this invention, by setting up a first conveyor belt, a positioning groove, a detection groove, an infrared rangefinder, a second conveyor belt, and a positioning plate, the device can detect the distance between the first conveyor belt with the detection groove and the infrared rangefinder through the infrared rangefinder, thereby accurately positioning the packaging bowl on the positioning groove. The positioning plate is moved by the second conveyor belt, thereby releasing the disposable spoon so that the disposable spoon falls accurately into the packaging bowl. This device can automatically add spoons to the packaging bowl and transport the packaging bowl with the spoon to the packaging machine for packaging. This method is more time-saving, labor-saving, and efficient. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments. Specific experimental conditions and methods not specified in the following embodiments are generally conventional methods well known to those skilled in the art.

[0020] Example 1: An automatic spoon-feeding mechanism, comprising a worktable 1, a bowl conveying assembly 2, and a spoon conveying assembly 3, characterized in that: the bowl conveying assembly 2 is provided on the upper side of the worktable 1, the bowl conveying assembly 2 includes a first mounting shell 21 fixedly connected to the upper side of the worktable 1, a first rotating shaft 22 rotatably connected to each of the two ends of the inner side of the first mounting shell 21, a first motor 23 fixedly mounted on the front side of the first mounting shell 21, the first motor 23 being connected to the first rotating shaft 22 on that side, a tensioned first conveyor belt 24 sleeved on the outer side of the first rotating shaft 22, a set of evenly distributed positioning grooves 25 provided on the first conveyor belt 24, a set of evenly distributed detection grooves 26 provided on the front side of the first conveyor belt 24, the first mounting... An mounting block 27 is fixedly connected to the front side of the shell 21. An infrared rangefinder 28 is fixedly connected to the upper side of the mounting block 27. A spoon conveying assembly 3 is provided on the rear side of the bowl conveying assembly 2. The spoon conveying assembly 3 includes two support frames 31 fixedly connected to the upper side of the workbench 1. A second mounting shell 32 is fixedly connected to the front side of each support frame 31. A second rotating shaft 33 is rotatably connected to the upper and lower ends of the inner side of the second mounting shell 32. A second motor 34 is fixedly installed on the front side of the second mounting shell 32. The second motor 34 is connected to the second rotating shaft 33 on this side. A tensioned second conveyor belt 35 is sleeved on the outer side of each of the second rotating shafts 33. A set of evenly distributed positioning plates 36 are fixedly connected to the outer side of each of the second conveyor belts 35.

[0021] Example 2: As Figures 1-6As shown, the automatic spoon-adding mechanism described in this embodiment differs from the mechanism described in Embodiment 1 only in that both the positioning groove 25 and the detection groove 26 are cylindrical grooves, and the detection groove 26 is located directly in front of the positioning groove 25. By detecting the position of the detection groove 26, the position of the packaging bowl on the positioning groove 25 can be detected. The mounting block 27 is located in the middle position in the left-right direction of the first mounting shell 21. The height of the probe of the infrared rangefinder 28 is the same as the height of the detection groove 26 located on the upper side. The distance between the infrared rangefinder 28 and the first conveyor belt 24 can be measured by the infrared rangefinder 28. When the detection groove 26... When the infrared rangefinder 28 is directly behind it, the data measured by the infrared rangefinder 28 changes; the two second conveyor belts 35 are symmetrically distributed on the left and right, and the second conveyor belts 35 are both located above the first conveyor belt 24. There is a gap between the second conveyor belts 35 and the first conveyor belt 24 that allows the packaging bowl to pass through. The second conveyor belts 35 can drive the positioning plates 36 to move synchronously; the positioning plates 36 are all bent soft rubber plates. The two sets of positioning plates 36 are symmetrically distributed on the left and right, and the two sets of positioning plates 36 are in contact and aligned at their closest ends. After the contacting parts of the two sets of positioning plates 36 move downward a certain distance, a disposable spoon can be released.

[0022] The automatic spoon-adding mechanism described in the embodiment is used as follows:

[0023] Before use, install the workbench 1 in a suitable position and connect the power supply. Install the packaging machine on the right side of the device. This device is equipped with an external controller. This device adopts a conventional technology external controller and is electrically connected to the first motor 23, the infrared rangefinder 28, and the second motor 34 respectively. The operating status of the first motor 23, the infrared rangefinder 28, and the second motor 34 can be adjusted by manually operating the external controller.

[0024] When this device is in operation, the operator starts the first motor 23, infrared rangefinder 28, and second motor 34 via an external controller. This device can be used in conjunction with feeding equipment for packaging bowls and disposable spoons. The packaging bowl feeding equipment places the packaging bowls onto the positioning slot 25 of the first conveyor belt 24, and the disposable spoon feeding equipment places the disposable spoons onto a support plate composed of two positioning plates 36. The continuously rotating first motor 23 drives a first rotating shaft 22, which is limited by the first mounting shell 21, to rotate, thus running the first conveyor belt 24 and causing the other first rotating shaft 22 to rotate synchronously. The positioning slot 25 allows the packaging bowls to move from left to right. Simultaneously, the infrared rangefinder 28, fixed by the mounting block 27, measures the distance between the infrared rangefinder 28 and the first conveyor belt 24. When the detection slot 26 reaches directly behind the infrared rangefinder 28, the data measured by the infrared rangefinder 28 changes. When the external controller detects this change in data from the infrared rangefinder 28, it can react quickly, activating the two second motors 34. By rapidly rotating a certain number of times, the second mounting shell 32 can be fixed above the first conveyor belt 24 via the support frame 31. The second motor 34 drives the second rotating shaft 33, which is limited by the second mounting shell 32, to rotate, causing the second conveyor belt 35 to run. This causes the two sets of positioning plates 36 to move synchronously, and the contact parts of the two sets of positioning plates 36 move downwards a certain distance, releasing a disposable spoon. The disposable spoon can accurately fall into the packaging bowl. Then, the packaging bowl with the spoon is carried by the first conveyor belt 24 to continue moving to the right, and then to the packaging machine for further packaging. The device can detect the distance between the first conveyor belt 24 with the detection slot 26 and the infrared rangefinder 28 through the infrared rangefinder 28, thereby positioning the packaging bowl on the positioning slot 25. The second conveyor belt 35 drives the positioning plate 36 to move, thereby releasing the disposable spoon and ensuring that the disposable spoon falls accurately into the packaging bowl. This device can automatically add a spoon to the packaging bowl and transport the packaging bowl with the spoon to the packaging machine for packaging, saving time and effort and increasing efficiency.

[0025] This utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
