Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of automatic tea cake packaging machines, specifically relating to an automatic tea cake packaging machine with a limiting structure. Background Technology
[0002] The core function of an automatic packaging machine lies in its ability to combine products in different forms (such as solids, liquids, powders, and granules) with various packaging materials (such as films, cardboard boxes, glass bottles, and plastic bags) using preset programs and mechanical structures to complete a packaging process that meets technological standards. The entire process requires virtually no or only minimal human intervention. Its core value lies in "automation," which achieves continuous and precise operation of the packaging process through the coordinated use of mechanical transmission, electrical control, and sensor detection technologies.
[0003] The production of tea cakes involves multiple processes, including raw material preparation and selection, fixation, rolling and shaping, drying, pile fermentation, weighing and steaming, drying and shaping, and packaging and storage. In the packaging stage, pillow-type automatic packaging machines are typically used. However, after drying and shaping, some tea cakes may have defects, such as variations in thickness. When these thicker tea cakes enter the packaging channel, they are highly susceptible to tearing of the packaging film, affecting packaging effectiveness and efficiency. Utility Model Content
[0004] The purpose of this invention is to provide an automatic tea cake packaging machine with a limiting structure, aiming to solve the problem in the prior art that some tea cakes may have defects, such as differences in thickness, after drying and shaping. When these thicker tea cakes enter the packaging channel, they are prone to causing the packaging film to break, affecting the packaging effect and efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic tea cake packaging machine with a limiting structure, comprising a control cabinet, a frame connected to the front end of the control cabinet, a cutting mechanism installed at the top of the frame, a heat sealing mechanism connected to the front end of the control cabinet, a film feeding mechanism connected to the front end of the control cabinet, a first conveyor belt connected to one side of the front end of the control cabinet, a second conveyor belt connected to the top of the frame, a support block connected to the top of the outer shell of the first conveyor belt, a threaded rod threaded through the surface of the support block, a guide rod threaded through the surface of the support block, a limiting block connected inside the support block, the threaded rod rotatably connected to the top of the limiting block, the guide rod connected to the top of the limiting block, a fixing block connected to the top of the outer shell of the first conveyor belt, an electric rod installed at the front end of the fixing block, a push plate connected to the output end of the electric rod, a storage box bolted to the outer shell of the first conveyor belt, and a sensor connected to the side wall of the support block.
[0006] As a preferred embodiment of the automatic tea cake packaging machine with a limiting structure according to this utility model, the limiting block can be connected to the support block by means of a guide rod and a threaded rod to form a threaded lifting connection.
[0007] In a preferred embodiment of the automatic tea cake packaging machine with a limiting structure according to this utility model, the extension length of the push plate via the electric rod is the same as that at the center of the storage box.
[0008] In a preferred embodiment of the automatic tea cake packaging machine with a limiting structure according to this utility model, the bottom end of the push plate is in contact with the first conveyor belt.
[0009] In a preferred embodiment of the automatic tea cake packaging machine with a limiting structure according to this utility model, the guide rod and the threaded rod have the same length.
[0010] As a preferred embodiment of the automatic tea cake packaging machine with a limiting structure of this utility model, the bottom end of the outer shell of the second conveyor belt is connected to two symmetrical mounting blocks, one of which is connected to a servo motor at its front end, and a guide plate is rotatably connected between the two mounting blocks.
[0011] As a preferred embodiment of the automatic tea cake packaging machine with a limiting structure of this utility model, the output shaft of the servo motor passes through the mounting block and is connected to the guide plate, and the guide plate is connected to the mounting block by the servo motor in a flipping manner.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Through the cooperation of the support block, threaded rod, guide rod, and limiting block, the operator only needs to easily rotate the threaded rod to lower it. The threaded rod will then drive the limiting block to move down synchronously. At the same time, the guide rod will descend smoothly along with the limiting block. As the limiting block continues to descend and gradually approaches the first conveyor belt, the operator can adjust the distance between the limiting block and the first conveyor belt. The position of the limiting block forms an effective height limiting structure. When defective tea cakes are conveyed to the automatic packaging machine through the first conveyor belt, the limiting block can effectively limit these defective tea cakes and prevent them from entering the normal packaging process. At this time, the fixing block, electric rod, push plate, storage box, and sensor work together. The sensor can detect the defective tea cakes blocked by the limiting block. Once detected, the electric rod immediately starts working, and its output end quickly extends to push the push plate forward, thereby accurately pushing the defective tea cake into the storage box for storage. This greatly improves the quality and efficiency of tea cake packaging production, effectively avoids defective tea cakes from being mixed with normal products, reduces subsequent quality inspection and rework costs, and ensures the stability and reliability of tea cake packaging production.
[0014] Through the coordination of the mounting block, servo motor, and guide plate, the servo motor is started, and its output shaft drives the guide plate to rotate, thereby adjusting the angle of the guide plate. This avoids the problem of inconsistent feeding speeds during the tea cake feeding process due to the different sizes of tea cakes. If the guide plate angle is fixed, it will not be able to adapt to different sizes of tea cakes. Small tea cakes may be fed too quickly, while large tea cakes may be fed slowly or even jammed, which will seriously affect the smoothness and stability of the production process. By dynamically adjusting the angle of the guide plate through this device, the guide plate can be adjusted to the most suitable angle according to the actual size of the tea cake, ensuring that tea cakes of all sizes can be fed at a stable and uniform speed. This greatly improves the efficiency of tea cake packaging production, reduces production delays and equipment failures caused by feeding problems, and ensures the continuity and efficiency of the entire production process.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5 This utility model provides the following technical solution: an automatic tea cake packaging machine with a limiting structure, including a control cabinet 1, a frame 2 connected to the front end of the control cabinet 1, a cutting mechanism 3 installed at the top of the frame 2, a heat sealing mechanism 4 connected to the front end of the control cabinet 1, a film feeding mechanism 5 connected to the front end of the control cabinet 1, a first conveyor belt 6 connected to one side of the front end of the control cabinet 1, a second conveyor belt 7 connected to the top of the frame 2, and a support block 8 connected to the top of the outer shell of the first conveyor belt 6, with threads on the surface of the support block 8. A threaded rod 9 is connected through the support block 8, and a guide rod 10 is connected through the surface of the support block 8. A limit block 11 is connected inside the support block 8. The threaded rod 9 is rotatably connected to the top of the limit block 11, and the guide rod 10 is connected to the top of the limit block 11. A fixing block 12 is connected to the top of the outer shell of the first conveyor belt 6. An electric rod 13 is installed at the front end of the fixing block 12. A push plate 14 is connected to the output end of the electric rod 13. A storage box 15 is installed on the outer shell of the first conveyor belt 6 by bolts. A sensor 19 is connected to the side wall of the support block 8.
[0024] In practical use, the automatic tea cake packaging machine mainly consists of the following parts: control cabinet 1, frame 2, cutting mechanism 3, heat sealing mechanism 4, film feeding mechanism 5, first conveyor belt 6, and second conveyor belt 7.
[0025] The cutting mechanism 3 consists of a drive motor and a rotating cutter disc. The output shaft of the drive motor is connected to the rotating cutter disc. When the drive motor is working, it can drive the rotating cutter disc to rotate, thereby cutting the packaged tea cake film.
[0026] The heat sealing mechanism 4 is composed of a hot roller, which can seal the tea cake in the film when it is working.
[0027] The film feeding mechanism 5 consists of a film unwinding frame and a guide column. When in use, the film is first fixed on the film unwinding frame, and then it passes through the guide column and is placed at the heat sealing mechanism 4.
[0028] During the operation, the tea cake is placed on the first conveyor belt 6 and then conveyed on the first conveyor belt 6 to the heat sealing mechanism 4. When it is fed into the heat sealing mechanism 4, the film will wrap around the outside of the tea cake. Then the heat sealing mechanism 4 will seal the tea cake in the film. At the same time, the tea cake will be conveyed from the first conveyor belt 6 to the second conveyor belt 7.
[0029] Afterwards, the second conveyor belt 7 continues to transport the tea cake into the cutting mechanism 3, where the film is cut by the cutting mechanism 3, and finally the tea cake is sent to the outside by the second conveyor belt 7.
[0030] Preferably, the limiting block 11 can be threadedly lifted and lowered to the support block 8 via the guide rod 10 and the threaded rod 9. The extension length of the push plate 14 via the electric rod 13 is the same as the center of the storage box 15. The bottom end of the push plate 14 is in contact with the first conveyor belt 6. The guide rod 10 and the threaded rod 9 are of the same length.
[0031] In actual use, the operator only needs to easily rotate the threaded rod 9 to make it slowly descend. As the threaded rod 9 descends, it will drive the limit block 11 to move down synchronously. During this process, the guide rod 10 will descend smoothly together with the limit block 11.
[0032] As the limiting block 11 continues to descend and gradually approaches the first conveyor belt 6, the operator can flexibly adjust the distance between the limiting block 11 and the first conveyor belt 6. When the limiting block 11 is in a specific position, an effective height limiting structure is formed.
[0033] When defective tea cakes are conveyed to the automatic packaging machine via the first conveyor belt 6, this height limiting structure comes into play. The limiting block 11 effectively limits these defective tea cakes, preventing them from entering the normal packaging process.
[0034] At the same time, the sensor 19 can sensitively detect the defective tea cake blocked by the limit block 11. Once detected, the electric rod 13 will start working immediately, and its output end will quickly extend to push the push plate 14 forward, thereby accurately pushing the defective tea cake into the storage box 15 for storage.
[0035] This operation greatly improves the quality and efficiency of tea cake packaging production, effectively prevents defective tea cakes from being mixed with normal products, reduces subsequent quality inspection and rework costs, and effectively ensures the stability and reliability of tea cake packaging production.
[0036] It is worth noting that the sensor 19 and the electric rod 13 are electrically connected to the control cabinet 1. In this way, when the sensor 19 detects a defective tea cake, it will send a feedback to the PLC controller in the control cabinet 1. Then the PLC controller will transmit the signal to the electric rod 13, thereby activating the electric rod 13.
[0037] Preferably, the bottom end of the outer shell of the second conveyor belt 7 is connected to two symmetrical mounting blocks 16. A servo motor 17 is connected to the front end of one of the mounting blocks 16, and a guide plate 18 is rotatably connected between the two mounting blocks 16. The output shaft of the servo motor 17 passes through the mounting block 16 and is connected to the guide plate 18. The guide plate 18 is connected to the mounting block 16 by the servo motor 17 to form a flip connection.
[0038] In practical use, when the servo motor 17 starts, its output shaft drives the guide plate 18 to rotate, thereby enabling flexible adjustment of the angle of the guide plate 18. In actual production, there are significant differences in the size of tea cakes of different specifications. If the angle of the guide plate 18 remains fixed, many problems will occur during the tea cake feeding process. Because it cannot accommodate tea cakes of different sizes, small tea cakes may be fed too quickly due to the relatively wide channel, while large tea cakes may be fed slowly due to the narrow channel, or even experience jamming. These situations will seriously affect the smoothness and stability of the production process, causing the production rhythm to be disrupted.
[0039] By dynamically adjusting the angle of the guide plate 18 using this device, the guide plate 18 can be precisely adjusted to the most suitable angle according to the actual size of the tea cake. In this way, tea cakes of all sizes can be fed at a stable and uniform speed, effectively avoiding the above-mentioned problems. This not only greatly improves the efficiency of tea cake packaging production, but also reduces production delays and equipment failures caused by feeding problems, and effectively ensures the continuity and efficiency of the entire production process.
[0040] Working principle: First, according to the size of the tea cake, the operator starts the servo motor 17 connected to the power supply. Then, the output shaft of the servo motor 17 starts to rotate, driving the guide plate 18 to rotate. After the guide plate 18 is adjusted to the required angle, the operator stops the operation of the servo motor 17.
[0041] Next, the operator rotates the threaded rod 9 to make it slowly descend. During the descent of the threaded rod 9, it will drive the limiting block 11 to move down synchronously. At the same time, the guide rod 10 will also descend smoothly along with the limiting block 11. As the limiting block 11 continues to descend and gradually approaches the first conveyor belt 6, the operator can flexibly adjust the distance between the limiting block 11 and the first conveyor belt 6, thus forming an effective height limiting structure.
[0042] When the operator places the tea cake on the first conveyor belt 6, if there are defective tea cakes, the limit block 11 will effectively limit these defective tea cakes and prevent them from entering the normal packaging process. At the same time, the sensor 19 can sensitively sense the defective tea cakes blocked by the limit block 11. Once a defective tea cake is detected, the electric rod 13 will start working immediately, and its output end will quickly extend to push the push plate 14 forward, thereby accurately pushing the defective tea cake into the storage box 15 for storage. Afterwards, the push plate 14 is retracted, without affecting the passage of subsequent tea cakes.
[0043] Then, the tea cake is sent to the heat sealing mechanism 4. When it is sent to the heat sealing mechanism 4, the film will wrap around the outside of the tea cake. Then the heat sealing mechanism 4 will seal the tea cake in the film. At the same time, the tea cake will be transported from the first conveyor belt 6 to the second conveyor belt 7.
[0044] Afterwards, the second conveyor belt 7 continues to transport the tea cake into the cutting mechanism 3, where the film is cut. Finally, the packaged tea cake is sent to the outside through the guide plate 18 at the end of the second conveyor belt 7, completing the entire packaging process.
[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
