Description

Technical Field

[0001] This utility model relates to the field of food production technology, and in particular to an automatic food sealing machine. Background Technology

[0002] An automatic carton sealing machine is a packaging device that automates the sealing of cartons using adhesive tape, completing the simultaneous sealing of both the top and bottom sides of the carton in one operation. Its core functions include: high-efficiency sealing, size adaptation, intelligent control, and multi-scenario application.

[0003] During the sealing process, the packed cartons enter the sealing machine via a conveyor chain, where they are secured on both sides by a clamping belt and conveyed forward. The front and rear short tongues of the cartons are flattened by a tongue presser, while the left and right long tongues are bent and flattened towards the center by guide plates. The adhesive applicator then tightly bonds the tape to the carton body.

[0004] However, in the above process, before the carton enters the sealing machine, the dimensions of the carton need to be manually input into the control system to adjust the spacing of the clamping belt and the height of the adhesive applicator. Before sealing cartons of different sizes, the size data needs to be manually input, and the control system will adjust it before sealing. The process is cumbersome and cannot intelligently recognize the carton data for adjustment, which affects the sealing efficiency.

[0005] Therefore, it is necessary to solve the above problems by using an automatic food sealing machine. Utility Model Content

[0006] The purpose of this invention is to provide an automatic food sealing machine to solve the problems mentioned in the background art.

A lifting plate is fixedly arranged at the output end of the vertical electric cylinder, and the lifting plate is fixedly connected to the inner side of the lifting frame.

[0014] Preferably, the top of the lifting frame is provided with a horizontal frame, and an auxiliary double-output electric cylinder is provided on the side of the horizontal frame near the carton body.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, by setting a pressing component, the two short tongues of the carton body are flattened and the two long tongues are pre-shaped. At the same time, the height of the carton body can be measured. After receiving the height data, the remote control center adjusts the overall height of the sealing component. By setting a transmission component to clamp and transmit the carton body, the width of the carton body can be measured. After receiving the height data, the remote control center adjusts the auxiliary clamping and feeding distance of the sealing component. This realizes intelligent identification of carton data and timely adjustment of components, thereby improving sealing efficiency.

[0017] 2. In this utility model, by controlling the extension of the output end of the lifting electric cylinder, the lifting rod is lowered, thereby driving the pressing plate and the shaping plate to flatten the short tongue of the carton body and pre-shape its long tongue. At the same time, the current height of the carton body is calculated based on the extension of the lifting electric cylinder, and the height data is transmitted to the remote control center.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] To address the issue that manually inputting dimensional data and adjusting components before sealing boxes of different sizes is required, which is cumbersome and lacks intelligent recognition of box data, thus affecting sealing efficiency, the following implementation method is proposed.

[0026] This utility model provides, for example Figures 1 to 4The automatic carton sealing machine for food shown includes an operating table 1, with a feeding platform 2 and a discharging platform 3 respectively at both ends of the operating table 1. A pressing component 4 is fixedly installed on the feeding platform 2, and a carton body 5 is placed on the feeding platform 2. A transmission component 6 and a sealing component 7 are installed on the operating table 1, and an adhesive tape body 8 is installed on the top of the sealing component 7. The machine also includes a remote control center, which is connected to the pressing component 4, the transmission component 6, and the sealing component 7 via electrical signals. The height and width data of the carton body 5 detected by the pressing component 4 and the transmission component 6 are transmitted to the remote control center via electrical signals. After receiving the data, the remote control center adjusts the height of the sealing component 7 and the auxiliary clamping and feeding distance of the carton to facilitate quick and accurate application of adhesive tape.

[0027] By setting up the pressing component 4, the two short tongues of the carton body 5 are flattened and the two long tongues are pre-shaped. At the same time, the height of the carton body 5 can be measured. After receiving the height data, the remote control center adjusts the overall height of the sealing component 7. By setting up the transmission component 6, the carton body 5 is clamped and transmitted. At the same time, the width of the carton body 5 can be measured. After receiving the height data, the remote control center adjusts the auxiliary clamping and feeding distance of the sealing component 7. This realizes intelligent identification of carton data and timely adjustment of components to improve sealing efficiency.

[0028] like Figure 2 As shown, the pressing assembly 4 includes a lifting rod 404, a pressing plate 405 is provided in the middle of the lifting rod 404, a shaping plate 406 is provided on the pressing plate 405, and first pressure sensors (not shown in the figure) are evenly arranged on the bottom surface of the pressing plate 405. Multiple first pressure sensors are provided to ensure that at least four first pressure sensors transmit pressure signals when the pressing plate 405 flattens the two short tongues of the carton body 5, so that the number of first pressure sensors that emit pressure signals determines that the short tongues are flattened; lifting blocks 403 are provided at both ends of the lifting rod 404, and a lifting electric cylinder 402 is fixedly connected to the top surface of the lifting block 403. The lifting electric cylinder 402 is fixedly installed on the lifting support frame 401, and the lifting support frame 401 is fixedly installed on the loading platform 2; a fixing block 407 is provided on the lifting rod 404, and a push motor 408 is installed on the bottom surface of the fixing block 407. A push plate 409 is fixedly installed at the output end of the push motor 408.

[0029] In use, the remote control center controls the output end of the lifting electric cylinder 402 to extend, thereby driving the lifting rod 404 to descend through the lifting block 403. The lifting rod 404 drives the pressing plate 405 and the shaping plate 406 to descend, flattening the four tongues of the carton body 5 until four or more first pressure sensors transmit pressure signals, indicating that the two short tongues have been flattened and the two long tongues have been pre-shaped, so that the carton body 5 can pass smoothly under the temporary pressing plate 706.

[0030] When four or more first pressure sensors transmit pressure signals, the remote control center receives the signals and controls the lifting electric cylinder 402 to stop extending. At the same time, the height of the carton body 5 is calculated based on the extension of the lifting electric cylinder 402, thereby controlling the sealing assembly 7 to adjust its height. Then, the push motor 408 is started, which drives the push plate 409 to rotate, thereby pushing the carton body 5 between the carton clamping conveyor belt 603.

[0031] By controlling the extension of the output end of the lifting electric cylinder 402, the lifting rod 404 is lowered, thereby driving the pressing plate 405 and the shaping plate 406 to flatten the short tongue of the carton body 5 and pre-shape its long tongue. At the same time, the current height of the carton body 5 is calculated based on the extension of the lifting electric cylinder 402, and the height data is transmitted to the remote control center. After receiving the data, the remote control center controls the sealing assembly 7 to adjust its height, thereby driving the tape body 8 to adjust to a suitable sealing height position, thus realizing automated and intelligent adjustment.

[0032] like Figure 3 As shown, the transmission assembly 6 includes a dual-output electric cylinder 601 for clamping cartons. The output end of the dual-output electric cylinder 601 is fixedly connected to a transmission plate 602. A clamping conveyor belt 603 is fixedly installed on the top of the transmission plate 602. The clamping conveyor belt 603 is located above the operating table 1. A second pressure sensor (not shown in the figure) is provided on the clamping conveyor belt 603. The second pressure sensor is preferably located on the top surface of the clamping conveyor belt 603 and is used to detect whether the surface of the clamping conveyor belt 603 is in close contact with the carton body 5. The pressure signal emitted by the second pressure sensor indicates that the clamping conveyor belt 603 is currently in close contact with the side of the carton body 5. The dual-output electric cylinder 601 for clamping cartons is fixedly installed on the operating table 1 by a mounting plate 604.

[0033] In use, the remote control center controls the output end of the dual-output electric cylinder 601 to retract, thereby driving the conveyor belt 603 to move closer together via the transmission plate 602 until the second pressure sensor sends a pressure signal. Upon receiving the signal, the remote control center controls the output end of the dual-output electric cylinder 601 to stop retracting. The conveyor belt 603 then drives the carton body 5 across the operating table 1, while simultaneously controlling the tape body 8 to seal the carton, until the conveyor belt 603 transfers the carton body 5 to the unloading table 3, completing the sealing process.

[0034] By setting up a dual-output electric cylinder 601 for clamping boxes and a second pressure sensor, the spacing of the clamping conveyor belt 603 is adjusted. The extension and retraction data of the dual-output electric cylinder 601 is transmitted to the remote control center. After receiving the data, the remote control center controls the sealing assembly 7 to adjust the auxiliary clamping distance, thereby temporarily clamping the top of the carton body 5 to ensure the stability of the carton during the sealing process, realize intelligent adjustment, and improve sealing efficiency.

[0035] like Figure 4 As shown, the sealing assembly 7 includes a lifting frame 701. Vertical electric cylinders 702, fixed to the operating table 1, are symmetrically arranged on the inner side of the lifting frame 701. A lifting plate 707 is fixedly installed at the output end of the vertical electric cylinder 702, and the lifting plate 707 is fixedly connected to the inner side of the lifting frame 701. A horizontal frame 703 is installed at the top of the lifting frame 701. An auxiliary double-output electric cylinder 704 is installed on the side of the horizontal frame 703 closest to the carton body 5. A carton feeding wheel 705 is fixedly connected to the output end of the auxiliary double-output electric cylinder 704. The distance between the two carton feeding wheels 705 is consistent with the spacing between the two carton clamping conveyor belts 603, ensuring the stability of the carton body 5 during the tape application process. A temporary pressure plate 706, fixed to the horizontal frame 703, is installed below the auxiliary double-output electric cylinder 704. When the carton body 5 passes under the temporary pressure plate 706, the temporary pressure plate 706 flattens the long tongue of the carton body 5, and the auxiliary tape body 8 seals the carton.

[0036] In use, the remote control center calculates the height of the carton body 5 based on the extension of the lifting electric cylinder 402, and then controls the output end of the vertical electric cylinder 702 to retract. The lifting plate 707 drives the lifting frame 701 to descend, which in turn drives the temporary pressure plate 706 to descend, so that the distance from the bottom surface of the temporary pressure plate 706 to the operating table 1 is the height of the carton body 5.

[0037] The remote control center controls the output end of the auxiliary dual-output electric cylinder 704 to retract by the same amount based on the retraction amount of the clamping dual-output electric cylinder 601, thereby driving the carton feeding wheels 705 to move closer to each other until they are pressed against the top of the side of the carton body 5. The auxiliary clamping conveyor belt 603 then transports the carton body 5, ensuring the stability of the sealing process.

[0038] The working principle of this utility model is as follows: First, the carton body 5 is pre-pressed. The operator places the carton body 5 on the loading platform 2. The output end of the lifting electric cylinder 402 is extended by the remote control center, thereby driving the lifting rod 404 to descend through the lifting block 403. The lifting rod 404 drives the pressing plate 405 and the shaping plate 406 to descend, flattening the four tongues of the carton body 5 until four or more first pressure sensors transmit pressure signals, indicating that the two short tongues have been flattened and the two long tongues have been pre-pressed and shaped. After receiving the signal, the remote control center controls the lifting electric cylinder 402 to stop extending.

[0039] Secondly, the sealing assembly 7 is adjusted. When four or more first pressure sensors transmit pressure signals, the remote control center calculates the height of the carton body 5 based on the extension of the lifting electric cylinder 402, controls the output end of the vertical electric cylinder 702 to retract, and drives the lifting frame 701 to descend through the lifting plate 707, thereby driving the temporary pressure plate 706 to descend, so that the distance from the bottom surface of the temporary pressure plate 706 to the operating table 1 is the height of the carton body 5.

[0040] Then, the carton body 5 is pushed out, and the remote control center starts the push motor 408, which drives the push plate 409 to rotate, thereby pushing the carton body 5 between the carton clamping conveyor belt 603 on the operating table 1.

[0041] Next, the carton body 5 is transferred. The remote control center controls the output end of the dual-output electric cylinder 601 to retract, thereby driving the carton conveyor belt 603 to move closer together through the transmission plate 602 until the second pressure sensor sends a pressure signal. The remote control center receives the signal and controls the output end of the dual-output electric cylinder 601 to stop retracting. The carton conveyor belt 603 then drives the carton body 5 across the operating table 1. At the same time, the output end of the auxiliary dual-output electric cylinder 704 is controlled to retract by the same amount, thereby driving the feeding wheels 705 to move closer together until they are pressed against the top of the side of the carton body 5. The auxiliary carton conveyor belt 603 then transfers the carton body 5.

[0042] Finally, the carton body 5 is sealed. When the carton body 5 passes under the temporary pressure plate 706, the temporary pressure plate 706 flattens the long tongue of the carton body 5. The remote control center controls the tape body 8 to seal the carton body 5 until the carton conveyor belt 603 conveys the carton body 5 to the unloading table 3, completing the sealing.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
