Description

Technical Field

[0001] This utility model relates to the field of cutting and positioning technology, and more specifically, to a cutting and positioning mechanism for an automated production line of foam packaging boxes. Background Technology

[0002] Foamed plastics are lightweight, strong, and shock-absorbing, making them widely used in the packaging industry. The size, specifications, and shape of foam packaging boxes need to be manufactured according to customer requirements. During production, foam sheets need to be cut into specific shapes and sizes to meet the requirements of different packaging scenarios. This necessitates a precise cutting and positioning mechanism to ensure cutting accuracy and quality.

[0003] Utility model patent CN217728909U discloses a cutting device for processing foam packaging boxes, including a processing table. The front of the processing table has a power groove. By starting a stepper motor, two conveyor rollers a and two conveyor rollers b are driven to fix the foam packaging box. A reduction motor starts and drives the drive wheel and driven wheel to rotate. The rotation of the drive wheel and driven wheel drives the conveyor rollers a and b to transport the foam packaging box to be cut. The advance amount is input on the panel of the meter counter, and the distance the foam packaging box moves on the surface of the processing table is measured by a probe. When the preset length is reached, the counter outputs a control signal to control the electric push rod to drive the cutting resistance wire downward to automatically cut the foam packaging box. This solves the problem that the size and angle of the cut foam packaging box may be deviated when manually controlling the cutting resistance wire to cut the foam packaging box.

[0004] Although the cutting equipment for processing foam packaging boxes facilitates automatic cutting of foam packaging boxes and prevents deviations in cutting size and angle, the device still has the following problems in actual use: Two geared motors drive the drive wheels separately; if the motor speeds are not synchronized sufficiently, the speeds of the conveyor rollers on both sides may be inconsistent, causing the foam material to shift or wrinkle during transport, affecting the cutting quality. Furthermore, the device still requires manual placement of the foam packaging boxes, resulting in low cutting efficiency. Therefore, we propose a slitting and positioning mechanism for automated foam packaging box production lines. Utility Model Content

The transmission component includes two support plates placed vertically opposite each other, and a horizontally placed conveyor belt is provided between the two support plates. A sensing component for sensing foam packaging boxes is installed on the top surface of the transmission component near the front end between the two support plates.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Please see Figures 1-6The automated production line for foam packaging boxes uses a cutting and positioning mechanism, which includes a transmission component 1. The transmission component 1 includes two vertically placed support plates 11, and a horizontally placed conveyor belt 14 between the two support plates 11. A sensing component 2 for sensing foam packaging boxes is installed on the top surface of the transmission component 1 between the two support plates 11 near the front end. A lifting component 3 is slidably connected between the two support plates 11. The lifting component 3 includes a first lifting box 31 and a second lifting box 32 arranged opposite to each other. Heating blocks 5 are slidably connected to the opposite side walls of the first lifting box 31 and the second lifting box 32. A cutting wire 51 is fixedly connected between the two heating blocks 5. A leveling component 4 is provided above the conveyor belt 14 on the opposite side walls of the two support plates 11.

[0037] In this embodiment, as Figure 3 As shown, the transmission assembly 1 also includes at least two transmission rollers 12. Several transmission rollers 12 are rotatably inserted between the opposite side walls of two support plates 11. A transmission wheel 13 is coaxially sleeved on the outer side of the transmission rollers 12. A transmission motor 15 is installed on the outer side wall of one of the support plates 11, and the output shaft of the transmission motor 15 passes through the side wall of the support plate 11 and is coaxially connected to one of the transmission rollers 12 located at the far end. The transmission motor 15 drives the transmission roller 12 at the far end to rotate, so that the transmission wheel 13 coaxially sleeved on the outer side of the transmission roller 12 drives the track 14 to transport the foam packaging box.

[0038] Furthermore, such as Figure 1 and Figure 6 As shown, the straightening assembly 4 includes two telescopic rods that pass through the second cylinder 43 corresponding to the side wall of the support plate 11. The ends of the telescopic rods of the second cylinder 43 are fixedly connected to clamping plates 41 for straightening the foam packaging box so that the foam packaging box will not tilt when it is cut. Auxiliary telescopic rods 45 are connected between the support plate 11 and the corresponding clamping plates 41 on both sides of the second cylinder 43. The auxiliary telescopic rods 45 prevent the clamping plates 41 from tilting and ensure the stability of the straightening assembly 4.

[0039] Furthermore, such as Figure 6 As shown, guide plates 44 are fixedly installed on both clamping plates 41 near the rear end of the support plate 11. The guide plates 44 are inclined in the direction of the corresponding support plate 11, so that the foam packaging box can be guided between the two clamping plates 41 and positioned. The opposing side walls of the two clamping plates 41 and the guide plates 44 are fixedly connected with buffer plates 42 to prevent the foam packaging box from being crushed. The bottom surfaces of the clamping plates 41 and the buffer plates 42 do not contact the track 14 to prevent the clamping plates 41 from crushing the foam packaging box.

[0040] It is important to note that, such as Figure 2As shown, the sensing component 2 includes a matching infrared transmitter 21 and an infrared receiver 22. The infrared transmitter 21 and the infrared receiver 22 are respectively fixedly installed on the top of the two support plates 11 and their positions correspond to each other. When the foam packaging box passes through the sensing component 2, the infrared signal is blocked and the infrared receiver 22 cannot receive the signal, triggering the subsequent positioning and cutting.

[0041] Furthermore, such as Figure 4 and Figure 5 As shown, a lead screw 311 is rotatably connected inside the first lifting box 31. A lifting motor 312 is installed at the bottom of the first lifting box 31. The output shaft of the lifting motor 312 is coaxially connected to the lead screw 311. The lifting motor 312 drives the lead screw 311 to rotate, causing the heating block 5 to move up and down to adjust the height of the cutting wire 51. A slide rod 321 is inserted inside the second lifting box 32. A first cylinder 34 is installed on the side wall of the first lifting box 31 or the second lifting box 32 near the bottom. The end of the telescopic rod of the first cylinder 34 is fixedly connected to the side wall of the second lifting box 32. The first cylinder 34 pushes the first lifting box 31 and the second lifting box 32 to slide horizontally to adapt to foam packaging boxes of different widths.

[0042] Furthermore, such as Figure 4 and Figure 5 As shown, one heating block 5 is threadedly connected to the outer side of the corresponding lead screw 311, and the other heating block 5 is slidably sleeved on the outer side of the corresponding slide rod 321. The two heating blocks 5 are respectively connected to an external power source through wires. The heated cutting wire 51 moves through the lifting assembly 3, and uses high temperature to melt the foam material to achieve precise cutting.

[0043] It is worth mentioning that, such as Figure 1 As shown, the two support plates 11 have grooves 111 on their sidewalls that are far apart from each other, allowing the lifting assembly 3 to slide horizontally. The depth of the grooves 111 is less than the thickness of the support plates 11. The opposite sidewalls of the first lifting box 31 and the second lifting box 32 are slidably engaged by sliders 33 that are adapted to the size of the grooves 111. The sliders 33 are adapted to the grooves 111, so that the lifting assembly 3 can slide horizontally between the support plates 11 under the drive of the first cylinder 34.

[0044] Finally, it should be noted that the transmission motor 15, infrared transmitter 21, infrared receiver 22, lifting motor 312, first cylinder 34, second cylinder 43, heating block 5, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0045] Working principle: In this embodiment, the slitting and positioning mechanism of the automated foam packaging box production line is used by the transmission motor 15 driving the transmission roller 12 to rotate, which drives the conveyor belt 14 to transport the foam packaging box forward. When the foam packaging box passes the sensing component 2 on the top surface of the transmission component 1, the infrared transmitter 21 and the infrared receiver 22 sense the foam packaging box and trigger a signal. At this time, the second cylinder 43 of the alignment component 4 pushes the clamping plate and uses the guiding function of the guide plate 44 to calibrate the foam packaging box to the center of the conveyor belt 14. Then, the lifting motor 312 drives the lead screw 311 to rotate, which drives the heating block 5 and the cutting wire 51 to move vertically to the required height. The external power supply makes the heating block 5 heat up. Finally, the first cylinder 34 pushes the first lifting box 31 and the second lifting box 32, which drives the high-temperature cutting wire 51 to melt the foam material and complete the slitting.

[0046] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
