Description
Technical Field
[0001] This utility model relates to the field of tea packaging equipment technology, and more specifically, it relates to an automatic tea bag feeding mechanism. Background Technology
[0002] To facilitate brewing and storage, and for aesthetic purposes, most tea packaging in the tea industry uses small bags weighing 5-10 grams. These bags are then placed into boxes to complete the tea packaging process.
[0003] Existing tea packaging machines can only pack tea leaves into bags. After the tea leaves are bagged, they generally need to be packed into boxes, and then the boxes are packed into cartons. For example, Chinese utility model patent application number CN202221012305.0 discloses a tea packaging production line, including a small bag tea packaging machine, a converging conveyor, a manual boxing conveyor, an automatic laminating machine, a heat shrink machine, and a manual boxing platform. The manual boxing conveyor is connected to the converging conveyor to receive the small bag finished products and to serve as a platform for manual boxing operations, conveying the manually boxed finished products forward.
[0004] In the aforementioned tea packaging production line, a confluence conveyor transports tea bags packaged by the small tea bag packaging machine to the manual boxing conveyor. Because the tea bags are directly transported via the confluence conveyor, a large number of tea bags simultaneously enter the manual boxing conveyor. Furthermore, these numerous tea bags tend to stack at both the confluence conveyor and the manual boxing conveyor, hindering boxing and resulting in low efficiency. Therefore, there is room for improvement. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic tea bag feeding mechanism to solve the above-mentioned technical problems.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic tea bag feeding mechanism, comprising: a feeding conveyor belt, a feeding alignment component, and a discharging grid conveyor belt; the feeding conveyor belt has a conveying direction perpendicular to the conveying direction of the discharging grid conveyor belt; the feeding alignment component is disposed at the discharging end of the feeding conveyor belt; the feeding alignment component is disposed above the discharging grid conveyor belt; a feeding monitoring component is disposed on the feeding alignment component for monitoring whether the corresponding grid on the discharging grid conveyor belt is empty; the feeding monitoring component is electrically connected to the feeding alignment component.
[0007] Specifically, the tea bags produced by the tea packaging machine are received by the feeding conveyor belt and transported to the unloading alignment component. The unloading alignment component opens and closes based on whether tea leaves are present at the corresponding grid on the discharge grid conveyor belt below, as monitored by the unloading monitoring component. If no tea leaves are present, the unloading alignment component opens, allowing the tea bag to fall into the grid of the discharge grid conveyor belt, thus completing the unloading process. The unloading alignment component and the discharge grid conveyor belt sequentially transport the tea bags to the next process, ensuring that only one tea bag is present in each grid of the discharge grid conveyor belt, preventing tea bags from piling up and affecting the production efficiency of subsequent processes. Multiple feeding conveyor belts and corresponding unloading alignment components can be installed on the discharge grid conveyor belt.
[0008] Optionally, the material feeding and alignment assembly includes: a support frame; the support frame is disposed on the discharge grid conveyor belt, the support frame is provided with a material feeding hopper, and the support frame is provided with a switch component for opening or closing the lower opening of the material feeding hopper; the upper opening of the material feeding hopper is directly opposite the discharge end of the feeding conveyor belt.
[0009] Specifically, after the tea packaging machine produces tea bags, the tea bags are conveyed into the feeding hopper via the feeding conveyor belt. At this time, the switching component closes the lower opening of the feeding hopper. When the feeding monitoring component detects that the grid below the feeding hopper is empty, the switching component opens, and the tea bags fall into the corresponding grid and are conveyed to the next process via the discharge grid conveyor belt.
[0010] Optionally, the hopper includes: a receiving enclosure and a supporting frame; the supporting frame is mounted on a support frame; the receiving enclosure is mounted on the upper end of the supporting frame; a through slot is provided on the supporting frame; the switching component passes through the through slot to open or close the lower opening of the supporting frame.
[0011] Specifically, the receiving enclosure receives the tea bags output from the feeding conveyor belt, and the tea bags fall into the supporting frame under the guidance of the receiving enclosure. At this time, the switching component passes through the through slot and closes the lower opening of the supporting frame. When the feeding monitoring component detects that the grid below the feeding hopper is empty, the switching component opens, and the tea bags are no longer restricted by the switching component and fall from the supporting frame into the corresponding grid, and are then transported to the next process by the discharge grid conveyor belt.
[0012] Optionally, the receiving enclosure is in the shape of an inverted triangle with one end open, and the open end of the receiving enclosure faces the feeding conveyor belt.
[0013] Specifically, the receiving enclosure is set in the shape of a c, with one end of the receiving enclosure opening facing the feeding conveyor belt. This allows for a more stable reception of tea bags output from the feeding conveyor belt, preventing the tea bags from passing over the receiving enclosure due to the excessive speed of the feeding conveyor belt.
[0014] Optionally, the receiving enclosure is inclined to one side facing the discharge end of the feeding conveyor belt, and the upper opening of the receiving enclosure is larger than the lower opening of the receiving enclosure.
[0015] Specifically, the inclined receiving enclosure with an upper opening larger than the lower opening helps to reduce the impact between the tea bag and the receiving enclosure when the tea bag comes into contact with the side of the receiving enclosure facing the feeding conveyor belt, allowing the tea bag to slide smoothly into the supporting frame.
[0016] Optionally, the receiving enclosure has clearance grooves on both sides that are adapted to the discharge end of the feeding conveyor belt.
[0017] Specifically, by opening clearance grooves on both sides of the receiving enclosure, the sides of the receiving enclosure can extend to the feeding conveyor belt, ensuring that the tea bags output from the feeding conveyor belt smoothly enter the receiving enclosure at a fixed angle.
[0018] Optionally, the switching component includes: two driving cylinders; the two driving cylinders are symmetrically arranged on both sides of the support frame; each of the output ends of the two driving cylinders is provided with a closed baffle; the two closed baffles pass through the through groove and then contact the lower opening of the closed support frame.
[0019] Specifically, when the tea bag falls from the feeding conveyor belt into the support frame, the output ends of the two drive cylinders extend, and the closed baffles contact the lower opening of the closed support frame. At this time, the tea bag is restricted by the closed baffles within the support frame. When the feeding monitoring component detects that the grid below the support frame is empty, the two drive cylinders drive the corresponding closed baffles to move in opposite directions. The two closed baffles separate and open the lower opening of the support frame, and the tea bag, no longer restricted by the closed baffles, falls into the grid below the support frame.
[0020] Optionally, the material feeding monitoring component includes an infrared transmitter and an infrared receiver; the infrared transmitter and infrared receiver are electrically connected to the material feeding alignment component.
[0021] Specifically, infrared rays are emitted by an infrared transmitter, reflected by the grid on the discharge grid conveyor belt, and then received by an infrared receiver. According to the principle of infrared ranging, if the time it takes for the infrared rays emitted by the infrared transmitter to be received by the infrared receiver changes, it can be determined that there are tea bags inside the grid of the discharge grid conveyor belt directly below the supporting frame.
[0022] In summary, this utility model has the following beneficial effects: It receives bagged tea bags produced by a tea packaging machine via a feeding conveyor belt and transports them to the unloading alignment component. The unloading alignment component checks whether tea leaves are present at the corresponding grid on the lower discharge grid conveyor belt, as monitored by the unloading monitoring component. If not, the unloading alignment component opens, allowing the tea bag to fall into the grid of the discharge grid conveyor belt, thus completing the unloading of the tea bag. By sequentially transporting the tea bags to the subsequent processes through the unloading alignment component and the discharge grid conveyor belt, it ensures that only one tea bag exists in each grid of the discharge grid conveyor belt, avoiding the stacking of tea bags and thus preventing the impact on the production efficiency of subsequent processes.

[0030] Example 1
[0031] This embodiment provides an automatic tea bag feeding mechanism, such as... Figure 1-3 As shown, it includes: a feeding conveyor belt 1, a discharge alignment component 2, and a discharge grid conveyor belt 3; the conveying direction of the feeding conveyor belt 1 is perpendicular to the conveying direction of the discharge grid conveyor belt 3; the discharge alignment component 2 is located at the discharge end of the feeding conveyor belt 1; the discharge alignment component 2 is located above the discharge grid conveyor belt 3; a discharge monitoring component is provided on the discharge alignment component 2 for monitoring whether the corresponding grid on the discharge grid conveyor belt 3 is empty; the discharge monitoring component is electrically connected to the discharge alignment component 2.
[0032] Specifically, the tea bags produced by the tea packaging machine are received by the feeding conveyor belt 1 and conveyed to the unloading alignment component 2. The unloading alignment component 2 opens and closes according to whether there is tea at the corresponding grid on the discharge grid conveyor belt 3 below, as monitored by the unloading monitoring component. If no tea is found, the unloading alignment component 2 opens, allowing the tea bag to fall into the grid of the discharge grid conveyor belt 3, thus completing the unloading of the tea bag. The unloading alignment component 2 and the discharge grid conveyor belt 3 sequentially convey the tea bags to the next process, ensuring that there is only one tea bag in each grid of the discharge grid conveyor belt 3, avoiding the stacking of tea bags and affecting the production efficiency of the next process. Multiple feeding conveyor belts 1 and corresponding unloading alignment components 2 can be installed on the discharge grid conveyor belt 3.
[0033] Optionally, the material feeding and alignment assembly 2 includes: a support frame 21; the support frame 21 is mounted on the discharge grid conveyor belt 3, the support frame 21 is provided with a material feeding hopper 22, and the support frame 21 is provided with a switch component 23 for opening or closing the lower opening of the material feeding hopper 22; the upper opening of the material feeding hopper 22 is directly opposite the discharge end of the feeding conveyor belt 1.
[0034] Specifically, after the tea packaging machine produces tea bags, the tea bags are conveyed into the feeding hopper 22 by the feeding conveyor belt 1. At this time, the switching component 23 closes the lower opening of the feeding hopper 22. When the feeding monitoring component detects that the grid below the feeding hopper 22 is empty, the switching component 23 opens, the tea bags fall into the corresponding grid, and are conveyed to the next process by the discharge grid conveyor belt 3.
[0035] Optionally, the switch component 23 includes: two drive cylinders 231; the two drive cylinders 231 are symmetrically arranged on both sides of the support frame 222; the output end of each of the two drive cylinders 231 is provided with a closed baffle 232; the two closed baffles 232 pass through the through groove 4 and then contact the lower opening of the closed support frame 222.
[0036] Specifically, when the tea bag falls from the feeding conveyor belt 1 into the support frame 222, the output ends of the two drive cylinders 231 extend, and the closing baffle 232 contacts the lower opening of the closed support frame 222. At this time, the tea bag is restricted within the support frame 222 by the closing baffle 232. When the feeding monitoring component detects that the grid below the support frame 222 is empty, the two drive cylinders 231 drive the corresponding closing baffle 232 to move in opposite directions. The two closing baffles 232 separate and open the lower opening of the support frame 222. The tea bag loses the restriction of the closing baffle 232 and falls into the grid below the support frame 222.
[0037] Optionally, the material feeding monitoring component includes an infrared transmitter and an infrared receiver; the infrared transmitter and infrared receiver are electrically connected to the material feeding alignment component 2.
[0038] Specifically, infrared rays are emitted by an infrared transmitter, reflected by the grid on the discharge grid conveyor belt 3, and then received by an infrared receiver. According to the principle of infrared ranging, if the time it takes for the infrared rays emitted by the infrared transmitter to be received by the infrared receiver changes, it can be determined that there are tea bags inside the grid of the discharge grid conveyor belt 3 directly below the supporting frame 222.

[0041] Specifically, the tea bags produced by the tea packaging machine are received by the feeding conveyor belt 1 and conveyed to the unloading alignment component 2.

If no tea is found, the unloading alignment component 2 opens, allowing the tea bag to fall into the grid of the discharge grid conveyor belt 3, thus completing the unloading of the tea bag. The unloading alignment component 2 and the discharge grid conveyor belt 3 sequentially convey the tea bags to the next process, ensuring that there is only one tea bag in each grid of the discharge grid conveyor belt 3, avoiding the stacking of tea bags and affecting the production efficiency of the next process.

At this time, the switching component 23 closes the lower opening of the feeding hopper 22. When the feeding monitoring component detects that the grid below the feeding hopper 22 is empty, the switching component 23 opens, the tea bags fall into the corresponding grid, and are conveyed to the next process by the discharge grid conveyor belt 3.
