The automatic edge material cutting device comprises a cutting platform and a supporting frame installed in the middle of the top of the cutting platform. Limiting assemblies are installed at the positions, located on the left side and the right side of the supporting frame, of the top of the cutting platform correspondingly, each limiting assembly comprises supporting plates fixed to the two sides of the top of the cutting platform and a connecting plate fixedly connected with the two supporting plates, and a double-threaded rod is rotationally connected between the two supporting plates. According to the plastic uptake sheet conveying device, a structure for limiting a plastic uptake sheet can be effectively formed at the input port and the output port of the supporting frame, and the situation that due to the fact that the plastic uptake sheet is affected by external factors, conveying is unstable is avoided; therefore, it is guaranteed that the two side edges of the blister sheet are always kept in linear transmission when being cut through the cutting knife, the edge materials on the two sides of the blister sheet are stably cut, and the flatness of the two side edges of the blister sheet after the edge materials are cut is guaranteed.

Description

Technical Field

[0001] This utility model relates to the technical field of cutting devices, and in particular to an automatic edge cutting device for blister sheets. Background Technology

[0002] Vacuum forming sheets are a type of plastic processing material. After the vacuum forming sheet is formed, an edge cutting device is needed to cut the two sides of the vacuum forming sheet to eliminate unevenness or defects on the two sides of the vacuum forming sheet.

[0003] Existing edge trimming devices for blister sheets typically use rollers to transport the blister sheet to the cutting blade. The cutting blade then removes the edge material from both sides of the blister sheet. However, during the transport of the blister sheet by the rollers, it may be affected by traction or device vibration, resulting in unstable transport and difficulty in maintaining a straight line. When the transport of the blister sheet is unstable, the angle at which it passes through the cutting device may change, ultimately making it difficult for the cutting blade to cut the blister sheet in a straight line, resulting in situations where one side is over-cut, the other side is under-cut, or the cuts on both sides are uneven.

[0004] Therefore, in response to the aforementioned technical problems with existing automatic edge trimming devices for thermoformed sheets, we have designed a targeted automatic edge trimming device for thermoformed sheets. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic edge cutting device for thermoformed sheets.

[0007] As a further embodiment of this utility model: a handle is fixedly connected to one end of the double-threaded rod, and the thread directions at both ends of the double-threaded rod are opposite.

[0008] As a further embodiment of this utility model: a fixing rod is also fixed between the two support plates of each set of limiting components. The fixing rod is located at the bottom of the double threaded rod and moves through the two limiting plates.

[0009] As a further embodiment of this utility model: the top of the limiting plate is slidably connected to the bottom of the connecting plate, the top of the connecting plate is engraved with scale lines, a fixing plate is fixed to one side of the limiting plate, and an indicator plate is fixed to the top of the fixing plate, with the indicator end of the indicator plate corresponding to the scale lines.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] This utility model discloses an automatic edge cutting device for blister sheets. Through the configuration of a support plate, double-threaded rod, fixing rod, limiting plate, and limiting roller, it effectively creates a limiting structure at the input and output ports of the support frame to prevent unstable transmission of the blister sheet due to external factors. This ensures that both sides of the blister sheet maintain a straight transmission as it is cut by the cutting blade, resulting in stable edge cutting and ensuring the flatness of the edges after trimming. This improves the quality of the trimmed blister sheet edge material and facilitates subsequent processing. Attached Figure Description

[0026] Please see Figure 1-5 An automatic edge cutting device for thermoformed sheet includes a cutting platform 1 and a support frame 2 installed at the center of the top of the cutting platform 1. Limiting components 11 are installed at the top of the cutting platform 1 and on both sides of the support frame 2. Each limiting component 11 includes a support plate 12 fixed to the top of the cutting platform 1 and a connecting plate 13 that connects the two support plates 12. A double threaded rod 14 is rotatably connected between the two support plates 12. Limiting plates 17 are threaded onto the threads at both ends of the double threaded rod 14. A groove 18 is provided on one side of the limiting plate 17, and a vertically rotatable connection is provided on the inner wall of the groove 18. There are multiple limiting rollers 19. When the blister sheet is in contact with the limiting rollers 19, the movement of the blister sheet will drive the multiple limiting rollers 19 to rotate, thereby reducing friction and ensuring the normal transmission of the blister sheet. Servo motors 6 are installed on both sides of the inner wall of the support frame 2. A cutting blade 7 is installed on the power output shaft of the servo motor 6. The start of the servo motor 6 can drive the cutting blade 7 to rotate, thereby cutting the passing blister sheet. A support plate 5 is provided on the inner wall of the support frame 2 and below each cutting blade 7. The support plate 5 plays the role of supporting the blister sheet at the cutting position, ensuring the cutting is carried out smoothly.

[0027] Please see Figure 3 In this embodiment, a handle 15 is fixedly connected to one end of the double threaded rod 14, and the thread directions at both ends of the double threaded rod 14 are opposite.

[0028] Specifically, two limiting plates 17 are threaded onto the double threaded rod 14. By turning the handle 15, the distance between the two limiting plates 17 can be adjusted to adapt to the width of the blister sheet and improve the applicability of the device.

[0029] Please see Figure 1 and Figure 3 In this embodiment, a fixing rod 16 is also fixed between the two support plates 12 of each set of limiting components 11. The fixing rod 16 is located at the bottom of the double threaded rod 14 and moves through the two limiting plates 17.

[0030] Specifically, the fixed rod 16 can restrict the movement trajectory of the limiting plate 17, ensuring that the limiting plate 17 moves smoothly in a straight line.

[0031] Please see Figure 1-2 In this embodiment, the top of the limiting plate 17 is slidably connected to the bottom of the connecting plate 13. The top of the connecting plate 13 is engraved with scale lines. A fixing plate 20 is fixed on one side of the limiting plate 17. An indicator plate 21 is fixed on the top of the fixing plate 20. The indicator end of the indicator plate 21 corresponds to the scale lines.

[0032] Specifically, a scale line is set on the top of the connecting plate 13, and an indicator plate 21 is set on the limiting plate 17, which allows the staff to intuitively observe the adjustment distance of the limiting plate 17 and ensure that the adjustment distances on the two sets of limiting components 11 are the same.

[0033] Please see Figure 1 and Figure 4 In this embodiment, an inlet roller 3 is rotatably connected to the left side of the inner wall of the support frame 2, and an outlet roller 4 is rotatably connected to the right side of the inner wall of the support frame 2. The height of the inlet roller 3 and the outlet roller 4 is the same as the height of the support plate 5. A guide roller 8 is rotatably connected to the left side of the top of the cutting platform 1, and a guide roller 9 is rotatably connected to the top of the cutting platform 1 and near the left side of the support frame 2. A limiting component 11 located on the left side of the top of the cutting platform 1 is located between the guide roller 8 and the guide roller 9. A guide roller 10 is rotatably connected to the right side of the top of the cutting platform 1, and a limiting component 11 located on the right side of the top of the cutting platform 1 is located to the left of the guide roller 10.

[0034] Specifically, the inlet roller 3 and the outlet roller 4 assist in ensuring the parallelism of the blister sheet at the cutting position, avoiding unevenness that could result in poor cutting quality. The guide roller 1 8 and the guide roller 2 9 convey the blister sheet into the support frame 2, and the guide roller 3 10 outputs the blister sheet from the support frame 2. The inlet roller 3, the outlet roller 4, the guide roller 1 8, the guide roller 2 9, and the guide roller 3 10 can all be driven by motors.

[0035] Working principle: The blister sheet is conveyed through the top of guide roller 1 8, the bottom of guide roller 2 9, the top of inlet roller 3, the top of outlet roller 4, and the bottom of guide roller 3 10. During the conveying process, the blister sheet is also placed between two sets of limiting components 11. By turning the handle 15, the distance between the two limiting plates 17 is adjusted until the limiting roller 19 on the limiting plate 17 contacts the side of the blister sheet. At this point, the limiting operation on both sides of the blister sheet is completed. The limiting roller 19 on the two limiting plates 17 is used to limit the longitudinal swaying or instability of the blister sheet. When the blister sheet passes the bottom of the cutting blade 7 and the top of the support plate 5, the cutting blade 7 can cut off the edge of the blister sheet due to its rotation, so that the two sides of the blister sheet after the edge is cut off remain flat and aesthetically pleasing.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
