[0019] Example 1
[0020] like Figures 1-3 As shown, the disposable tableware packaging machine proposed in this embodiment includes a frame 1, a fully automatic heat shrink packaging machine 4, two film unwinding rollers 5, and two heat pressing and bonding devices.
[0021] A belt conveyor is mounted on frame 1; two mounting side plates 3 are arranged side by side on frame 1; a fully automatic heat shrink packaging machine 4 is located on one side of the belt conveyor. The working principle and process of the fully automatic heat shrink packaging machine 4 are existing technologies and will not be described in detail here; two film unwinding rollers 5 are rotatably mounted above the two mounting side plates 3; two upper limit rollers 61 are arranged side by side below the two film unwinding rollers 5, and lower limit rollers 62 are arranged directly below the upper limit rollers 61. The upper limit rollers 61 and the lower limit rollers 62 are rotatably mounted on the two... Between the mounting side plates 3; both ends of the mounting side plate 3 on one side are connected to the first sensor mounting bracket 12, and the ends of the two first sensor mounting brackets 12 are each equipped with a first ranging sensor 7; two hot press bonding devices are symmetrically installed on both sides of the mounting side plate 3. The hot press bonding device includes a roller frame 8, a hot press roller 9, a fixing frame 10 and an electric push rod 11. Both ends of the fixing frame 10 are connected to the mounting side plates 3 on both sides respectively. The electric push rod 11 is installed on the fixing frame 10 and its output shaft is connected to the roller frame 8. The hot press roller 9 is rotatably installed on the roller frame 8.
[0022] Two second sensor mounting brackets 14 are connected to the mounting side plate 3 on one side, and a second distance sensor 13 is installed on each of the two second sensor mounting brackets 14. The second distance sensor 13 can detect the thickness of the film on the unwinding roller 5. Before the film is exhausted, the switch of the electric heater on the hot press roller 9 can be turned on, which can save energy. It should be noted that the hot press roller 9 is heated by an electric heater, which is powered by a battery or an electric slip ring.
[0023] The control panel 20 is installed on the side panel 3. The control panel 20 adopts a combination of human-machine interface and programmable logic controller. The control panel adopts a combination of HMI human-machine interface and PLC programmable logic controller. HMI provides users with an intuitive and user-friendly operating interface, and various commands can be easily issued by touching the screen.
[0024] The working principle of this technical solution is as follows:
[0025] The amount of heat-shrinkable film wound on each unwinding roller 5 is limited, so it needs to be replaced immediately when the film is exhausted. In this technical solution, two unwinding rollers 5 are provided. The unwinding rollers 5 are detachably mounted on two mounting side plates 3. Specifically, the end shaft of the unwinding roller 5 is mounted on the mounting side plate 3 through bearings and bearing seats. The bearings are mounted on the shaft of the unwinding roller 5 and on the bearing seats. The bearing seats are detachably mounted on the mounting side plate 3 by bolts and other fasteners. The unwinding rollers 5 can be easily removed when replenishing the material.
[0026] For ease of description, the right side referred to in this technical solution is... Figure 2 As shown, when the right-side membrane is about to run out, the detection end of the first distance sensor 7 on the right side is no longer obstructed. The detection data of the first distance sensor 7 changes and is fed back to the control panel 20. The control panel 20 immediately controls the start of the electric push rod 11 on the left side to drive the roller frame 8 and the hot press roller 9 to move synchronously to the right. In the initial state, the left-side membrane is partially pulled out to facilitate bonding with the right-side membrane. The hot press roller 9 pushes the left-side membrane closer to the right-side membrane. When the two membranes contact each other, the hot press bonding is completed. The right-side membrane continues to be pulled, which in turn drives the left-side membrane to move. When the entire right-side membrane is bonded to the left-side membrane, the left hot press roller 9 is driven to reset. Then, the right-side membrane is replenished. In summary, this technical solution can achieve hot press bonding of the membrane during the membrane feeding process, so that the equipment can run without stopping, saving the time of stopping to change the membrane and replenish the material, and greatly improving the production efficiency of the device.
[0027] Example 2
[0028] like Figure 1 , Figure 3 as well as Figure 4As shown, the disposable tableware packaging machine proposed in this embodiment, compared with the first embodiment, includes a belt conveyor comprising a conveyor belt 201, a servo motor 203, and two drive rollers 202. The two drive rollers 202 are rotatably mounted at both ends of the frame 1, and the conveyor belt 201 is sleeved on the outer periphery of the two drive rollers 202. The servo motor 203 is mounted on the frame 1 and its output shaft is connected to the rotating shaft of the drive rollers 202. The servo motor 203 is started to drive the drive rollers 202 to rotate, and the rotation of the drive rollers 202 in turn drives the conveyor belt 201 to move.
[0029] Multiple limiting devices are equidistantly installed on the conveyor belt 201. Each limiting device includes at least three sets of limiting components. Each limiting component includes a limiting rod 16, a fixing block 17, a first limiting block 18, and a second limiting block 19. The fixing block 17 is fixed on the conveyor belt 201 and passes through the inner and outer sides of the conveyor belt 201. The limiting rod 16 movably passes through the fixing block 17. The second limiting block 19 and the first limiting block 18 are respectively connected to the upper and lower ends of the limiting rod 16. The upper end of the fixing block 17 has a rectangular groove 171 for the second limiting block 19 to be inserted. A guide plate 15 is connected to the frame 1. The guide plate 15 is located inside the conveyor belt 201. The left section of the guide plate 15 is inclined downwards, and the right section is horizontal.
[0030] Both drive rollers 202 have annular grooves 2021 in the middle. The annular grooves 2021 are designed to ensure the smooth movement of the limiting components.
[0031] In this embodiment, the limiting device can be used to position the tableware. When the first limiting block 18 contacts the left section of the guide plate 15, the limiting rod 16 gradually moves upward as the conveyor belt 201 moves. When all the limiting components on the limiting device rise to the set position, the tableware can be placed in the area formed by the multiple limiting components. When the first limiting block 18 separates from the guide plate 15, the limiting rod 16 moves downward. At this time, the second limiting block 19 is inserted into the inner side of the rectangular groove 171, so that the second limiting block 19 is flush with the outer surface of the fixing block 17 and the conveyor belt 201.
[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
