Description

Technical Field

[0001] This utility model relates to the field of acrylic processing technology, specifically a cutting device for acrylic panel processing. Background Technology

[0002] Acrylic, also known as PMMA or plexiglass, is chemically named polymethyl methacrylate. It is an important plastic polymer material that was developed relatively early. It has good transparency, chemical stability and weather resistance, is easy to dye and process, and has a beautiful appearance. It is widely used in the construction industry and can usually be divided into cast sheets, extruded sheets and molding compounds.

[0003] A search revealed that Chinese patent CN221112053U discloses a positioning device for cutting acrylic sheets. This device uses a pulley system to drive a second rotating shaft, which in turn drives a first and second conveyor roller. The rotation of these rollers simultaneously moves the sheet material, thus feeding it into the machine. Continuous feeding allows for continuous cutting, improving the cutting efficiency of the acrylic sheet. A pressure plate, secured by a rubber sheet, further restricts the sheet material after it has been fed to the appropriate position, enhancing cutting stability. By setting stops, the feeding distance can be limited, improving cutting accuracy. However, this device presents the following technical problems:

[0004] This device has positioning accuracy issues when processing thinner sheets. Due to the lack of support on the bottom front of the sheet, when the extension length is slightly larger, the front end will bend due to gravity, making it impossible for the stop to be precisely positioned, which ultimately affects the accuracy of the cutting size. It cannot meet the processing needs of thin sheets and has limitations. Therefore, we propose an improved acrylic panel cutting device. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0026] like Figures 1 to 3 As shown, a cutting device for processing acrylic panels includes: a housing 1, a transport table 2 fixed inside the housing 1, a cutting groove 21 on the left side of the transport table 2, a support platform 22 on the left side of the cutting groove 21, a first rotating shaft 221 passing through the center of the right side of the support platform 22, a first protrusion 222 fixed on the left side of the support platform 22, two sets of connecting parts 431 fixed at the center of the bottom end of the support platform 22, an L-shaped receiving plate 23 frictionally connected to the left side of the support platform 22, a second protrusion 231 fixed on the right side of the L-shaped receiving plate 23, a support column 232 fixed on the right side of the bottom end of the L-shaped receiving plate 23, and the front end of the housing 1 near... A motor 4 is installed near the bottom edge. The output end of the motor 4 passes through the outer casing 1 and is fixedly connected to a second rotating shaft 41. Two sets of crown gears 412 are fixedly connected to the outside of the second rotating shaft 41. A second gear 42 is frictionally connected to the left side of the crown gear 412. A second lead screw 421 is fixedly connected to the center of the second gear 42. Support plates 44 are rotatably connected to the left and right ends of the second lead screw 421 through bearings. Push blocks 422 are movably connected to the outside of the two sets of second lead screws 421. Two sets of mounting blocks 423 are fixedly provided at the front and rear ends of the top of the push blocks 422. Connecting rods 43 are rotatably connected inside the two sets of mounting blocks 423 through bolts.

[0027] In this implementation scheme: the transport table 2 can prevent the acrylic sheet that needs to be cut from being placed on it; the reserved cutting groove 21 can prevent the cutting blade from damaging the transport table 2; the support table 22 provides stable support for the front end of the sheet, effectively solving the positioning accuracy problem caused by the thin sheet sagging due to gravity; the first rotating shaft 221 serves to connect the support table 22 and the outer shell 1; the L-shaped receiving plate 23 can smoothly catch the sliding acrylic sheet, ensuring the safety of operation; the motor 4 serves to output power, which can drive the internal gear structure to rotate and drive the support table 22 to move, so as to achieve the purpose of support and unloading.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, cavities 13 are provided inside the front and rear ends of the left side of the outer casing 1. A first lead screw 15 is inserted inside the cavity 13. A knob 12 is fixedly connected to the left side of the first lead screw 15 through the outer casing 1. A guide groove 14 is provided on the inner side of the outer casing 1 facing each other. A scale 141 is provided on the top of the guide groove 14. A slider 151 is movably connected to the outside of the first lead screw 15. A positioning plate 152 is fixedly connected to the inner side of the slider 151 through the guide groove 14.

[0029] In this implementation scheme: the knob 12 drives the internal first lead screw 15 to rotate, the guide groove 14 is connected to the cavity 13, the slider 151 slides inside it and plays a guiding role, the scale 141 plays a role in assisting positioning, eliminating the need to find an extra ruler to measure, which is convenient and accurate, and the positioning plate 152 plays a positioning role.

[0030] like Figure 1 , Figure 2 As shown, the front and rear ends of the first rotating shaft 221 are fixedly connected to the outer shell 1, and the first rotating shaft 221 is rotatably connected to the support platform 22. The positions of the first protrusion 222 and the second protrusion 231 are corresponding.

[0031] In this implementation scheme: the first rotating shaft 221 fixes the right side of the support platform 22 on the same horizontal line as the transport platform 2. The left side of the support platform 22 rotates up and down around the first rotating shaft 221. When it is lifted, the acrylic sheet is in a horizontal state during positioning and cutting, and will not be bent. When the left side of the support platform 22 falls to the contact engagement between the first protrusion 222 and the second protrusion 231, it stops falling. At this time, the support platform 22 and the L-shaped receiving plate 23 are on the same plane, and the cut acrylic sheet can be cut.

[0032] like Figure 2 and Figure 3 As shown, the crown gear 412 meshes with the second gear 42, and the motor 4 forms a linkage structure with the crown gear 412 and the second gear 42. The second lead screw 421 is threadedly connected to the push block 422, and the second gear 42 forms a linkage structure with the push block 422 through the second lead screw 421.

[0033] In this implementation plan: the motor 4 is started, which drives the two sets of crown gears 412 to rotate through the second rotating shaft 41. The second gear 42 rotates synchronously through meshing. Since the second gear 42 is fixedly connected to the second lead screw 421, it then drives the second lead screw 421 to rotate, which in turn drives the threaded push block 422 to move left and right in a linear motion.

[0034] like Figure 2 As shown, the connecting rod 43 is rotatably connected to the connecting piece 431 by bolts, and the connecting rod 43 and the support platform 22 form a linkage structure through the connecting piece 431.

[0035] In this implementation plan: the movement of the push block 422 drives the connecting rod 43 through the connector 431 to lift or lower the support platform 22.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, the first lead screw 15 is threadedly connected to the slider 151, and the first lead screw 15 forms a linkage structure with the positioning plate 152 through the slider 151.

[0037] In this implementation scheme: Rotating the knob 12 causes the first lead screw 15 to rotate, which drives the slider 151 to move left and right, and through the slider 151, drives the positioning plate 152 to move left and right, thereby realizing the positioning work of the positioning plate 152.

[0038] like Figure 1 , Figure 2 As shown, the bottom end of the positioning plate 152 is at the same level as the transport platform 2.

[0039] In this implementation scheme: the positioning plate 152 is adjusted to the required position, and the acrylic plate is slid to the left until the left side hits the right side of the positioning plate 152 to complete the positioning. The positioning plate 152 has a certain height, so it is suitable for acrylic plates of most thicknesses.

[0040] like Figure 1 , Figure 3 As shown, a crossbeam 3 is fixed on the top inner side of the outer casing 1, and a cutting mechanism 31 is provided inside the crossbeam 3, with the position of the cutting mechanism 31 corresponding to the cutting groove 21.

[0041] In this implementation scheme: the cross frame 3 serves to support the internal cutting mechanism 31. The cutting mechanism 31 is existing technology and will not be described in detail here. The position of the cutting mechanism 31 corresponds to the cutting groove 21 to prevent the cutting tool from damaging the transport table 2.

[0042] Working principle: When using this acrylic panel processing cutting device, the operator first rotates the knob 12 to rotate the internal first lead screw 15 structure according to the required acrylic sheet size, moving the positioning plate 152 to the predetermined size position. The acrylic sheet to be processed is then placed on the transport table 2 and pushed to the left until it is close to the positioning plate 152 to complete the positioning. The horizontal support table 22 effectively prevents the front end of the thin sheet from sagging due to gravity, which would cause inaccurate positioning. The cutting mechanism 31 is controlled by the PLC controller to complete the cutting of the acrylic sheet. Then, the motor 4 is turned on by the PLC controller, and the motor 4 operates... The mechanism uses a gear structure to rotate the second lead screw 421, which drives the push block 422 to slide to the right. The connecting rod 43 lowers the left side of the support platform 22 to the same plane as the L-shaped receiving plate 23, allowing the cut acrylic sheet to be cut. This ensures safe operation. After cutting, the PLC controller controls the second lead screw 421 to rotate in the opposite direction, causing the push block 422 to move to the left and reset, lifting the support platform 22 to a horizontal position, allowing the acrylic sheet to be cut again. The motor model mentioned above is ZMYB-380. The above motor model is for reference only and should meet the working requirements.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
