Description

Technical Field

[0001] The invention relates to the technical field of laminating machines, and in particular to a fully automatic laminating machine frame with a trimming and discharging structure. Background Art

[0002] The working principle of the fully automatic laminating machine is to coat the laminating liquid on the substrate in a certain way, and then solidify the coated film through processes such as drying and cooling, thereby forming a product with specific functions. At present, there are laminating machines that can coat both sides at the same time, that is, they can coat the laminating liquid on both sides of the substrate at the same time, further improving production efficiency.

[0003] During the laminating process, due to the flow and solidification of the coating on the substrate, redundant and irregular coatings may be formed on the edge parts. These parts not only affect the aesthetics of the product, but may also affect the performance of the product, so edge trimming is required. The existing automatic laminating machine uses the rotating cutting wheel on its frame to trim the two sides of the finished product. One end of the waste material passes through a discharge pipe. A fan is installed on the mounting end of the discharge pipe. The fan is used to blow the waste material to the discharge end of the discharge pipe and discharge it.

[0004] The cutting wheels on the above-mentioned automatic laminating machine frame are usually only two groups, and are arranged on the left and right sides to perform trimming operations on both sides of the finished product. During long-term use, the cutting wheels will gradually wear out due to friction with the material. This wear will not only affect the accuracy and quality of trimming, but may also cause burrs, unevenness and other problems in the trimming process, which are often discovered by staff during the operation of the equipment. To avoid a decrease in the quality of trimming, staff need to control the entire automatic laminating machine to stop working and then replace the damaged cutting wheels, which seriously affects the overall production efficiency. Therefore, the present application provides a fully automatic laminating machine frame with a trimming and discharging structure to meet the needs. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: Reference Figure 1-3 The frame of a fully automatic laminating machine with a trimming and discharging structure shown in the figure includes a frame 1 with multiple conveying rollers, a limit rod 2 and an adjusting screw 3 are arranged on the frame 1, two mounting plates 4 are installed on the limit rod 2 and the adjusting screw 3, a driving cylinder 8 is arranged on the two mounting plates 4, and a cutting wheel 6 driven by a driving motor 7 is arranged on the output end of the driving cylinder 8, a discharging pipe 5 is arranged on the frame 1, and two feeding openings are arranged on the discharging pipe 5, the mounting end of the discharging pipe 5 is connected to the air outlet of the fan, and multiple groups of cutting wheels 6 are arranged on the output end of each driving motor 7, and an automatic switching unit is also included, which can automatically switch the cutting wheel 6 when the fully automatic laminating machine is working.

[0019] As a preferred implementation in this embodiment, Figure 2-3 As shown, the automatic switching unit includes a hollow disc 9 with an opening at the right end, a rotating motor 12 and an L-shaped mounting rod 14; The lower end of the L-shaped mounting rod 14 passes through the axis of the hollow disc 9 and is rotatably connected to the hollow disc 9 through the mounting bearing 13. The L-shaped mounting rod 14 is connected to the output end of the driving cylinder 8 through the connecting frame 15. The rotating motor 12 is mounted on the upper end of the L-shaped mounting rod 14. A rotating gear is mounted on the output end of the rotating motor 12, and the rotating gear is gear-connected with a circular gear ring 10 provided on the outer wall of the hollow disc 9. A sealing plate 11 is provided on the right end of the hollow disc 9, and no less than five sets of rotating shafts 16 are installed on the sealing plate 11, and a first driving gear 18 is fixed on the end of the rotating shaft 16 extending to the inner cavity of the hollow disc 9, and the first driving gear 18 is gear-engaged with a transmission gear ring 23 rotatably arranged in the inner cavity of the hollow disc 9, and a cutting wheel 6 is detachably installed on the end of the rotating shaft 16 extending to the outside of the sealing plate 11; The driving motor 7 is mounted on the outer wall of the hollow disc 9, and the output end of the driving motor 7 is located in the inner cavity of the hollow disc 9 and is fixedly connected to the second driving gear 24, and the second driving gear 24 is gear-engaged with the transmission gear ring 23; The driving cylinder 8, the driving motor 7 and the rotating motor 12 are all electrically connected to the PLC controller.

[0020] During operation, the driving motor 7 is controlled by the PLC controller, and the transmission gear ring 23 is driven to rotate by the second driving gear 24, and the multiple cutting wheels 6 are driven to rotate by the transmission gear ring 23, and only the cutting wheel 6 at the bottom will cut the finished product. When the cutting wheel 6 needs to be replaced, the rotating motor 12 can be controlled by the PLC controller to drive the hollow disc 9 to rotate, and the rotation of the hollow disc 9 can drive the multiple cutting wheels 6 arranged thereon to rotate, and finally the cutting wheel 6 (denoted as B) similar to the original bottom cutting wheel 6 (denoted as A) is replaced to the original bottom cutting wheel 6 position and the substrate is trimmed. During the rotation of the hollow disc 9, after B cuts through the substrate, as the hollow disc 9 continues to rotate, the cutting blade of A starts to separate from the substrate and finally moves to the top of the substrate. At this time, the automatic replacement of the cutting wheel 6 is completed. When this cutting wheel is damaged, the above operation can be repeated to replace the next cutting wheel 6.

[0021] It should be noted that the number of cutting wheels 6 is not less than five groups (no more than seven groups at most), which is beneficial to the cutting edge of A that starts to separate from the substrate after B cuts through the substrate during the rotation of the hollow disc 9, as the hollow disc 9 continues to rotate, so that the substrate can be cut normally and continuously when the cutting wheels are switched. At the same time, the increase in the number of cutting wheels 6 is beneficial to extending the time for operators to replace damaged cutting wheels 6 and avoiding frequent replacement.

[0022] As a preferred implementation manner in this embodiment, it also includes a first energy-saving unit to reduce the number of cutting wheels 6 performing non-edge cutting rotational motion when the drive motor 7 works normally.

[0023] The purpose is to reduce the load of the drive motor 7 and save electric energy.

[0024] As a preferred implementation in this embodiment, Figure 4-5As shown, the first energy-saving unit includes a plurality of sliders 17 and a plurality of rectangular openings. The plurality of sliders 17 are rotatably disposed on corresponding rotating shafts 16 through bearings, and both ends of the sliders 17 are slidably disposed in slide grooves 22 opened on the inner walls of the corresponding rectangular openings.

[0025] Taking the case where there are five groups of cutting wheels 6 as an example, when the cutting wheels 6 at the bottom are trimming the substrate, the two groups of cutting wheels 6 at the top will slide due to gravity, thereby causing the first driving gears 18 on the two groups of cutting wheels 6 at the top to separate from the transmission gear ring 23, and the driving motor 7 can only drive the three groups of cutting wheels 6 at the bottom to rotate at the same speed, thereby reducing the number of cutting wheels 6 performing non-trimming rotational motion, reducing the load of the driving motor 6, and saving electric energy; When the cutting wheel 6 is switched, as the hollow disc 9 rotates, the first driving gear 18 (which is installed on the cutting wheel 6 close to the switched cutting wheel 6) 18 which is not in contact with the transmission gear ring 23 will move obliquely outward and engage with the transmission gear ring 23 (at this time, the cutting wheel 6 corresponding to the first driving gear 18 is still located directly above the substrate, and the cutting edge of the cutting wheel 6 to be switched still penetrates the substrate. After each switching 6 is replaced, its drive can only drive the three groups of cutting wheels 6 below to rotate.

[0026] As a preferred implementation manner in this embodiment, a second energy-saving unit is further included to further reduce the number of cutting wheels 6 performing non-edge cutting rotational motion when the drive motor 7 works normally.

[0027] The purpose is to further reduce the load of the drive motor 7 and save electric energy.

[0028] As a preferred implementation in this embodiment, Figure 4-7 As shown, the second energy-saving unit includes a plurality of L-shaped rods 19 and a driving disc 20 with an annular groove 21; One end of the plurality of L-shaped rods 19 is rotatably connected to the corresponding rotating shaft 16, and the other ends of the plurality of L-shaped rods 19 are slidably disposed in the annular groove 21; The driving disc 20 is fixed to the lower end of the L-shaped mounting rod 14, and the axis of the driving disc 20 is located directly below the axis of the hollow disc 9; During operation, the cutting wheel 6 at the bottom rotates and performs edge trimming on the substrate.

[0029] Under this structural design, when the cutting wheel 6 located at the bottom is cutting the substrate, the other cutting wheels 6 do not rotate. Since the driving disc 9 is eccentrically arranged and located directly below the axis of the hollow disc 9, the distances between the non-asymmetric points on the annular groove 21 arranged on the driving disc 9 and the inner wall of the hollow disc 9 are different. refer to Figure 7, mark the five groups of L-shaped rods 19 whose ends are located in the annular groove 21 with C, D, E, F, and G respectively. When trimming is performed, only the cutting wheel 6 corresponding to C performs trimming operation on the substrate. When the cutting wheel 6 corresponding to C is switched, for example, when the hollow disc 9 rotates clockwise, C, D, E, F, and G rotate clockwise along the path of the annular groove 21 (the driving disc 20 always remains stationary). As the rotation continues, the cutting wheel 6 corresponding to D will move outward and finally complete the tooth engagement with the transmission gear ring 23 before contacting the substrate. Continue to rotate, and the cutting wheel 6 corresponding to D moves to the cutting wheel 6 corresponding to C, and the cutting wheel 6 corresponding to C moves to the cutting wheel 6 corresponding to G (at this time, the rotating shaft 16 on the cutting wheel 6 corresponding to C is separated from the transmission gear ring 23, and the cutting wheel 6 of the cutting wheel 6 corresponding to C begins to be separated from the gear engagement after the cutting wheel 6 moves to the top of the substrate). The remaining cutting wheels 6 are replaced to similar cutting wheel 6 positions.

[0030] Through the design of this structure, when the driving motor 7 performs the trimming operation, only one set of cutting wheels 6 rotates, which can effectively save electric energy.

[0031] It should be noted that: Figure 7 , the vertical symmetry line of the hollow disk 9 coincides with the vertical symmetry line of the driving disk 21; secondly, the tooth connection gap between two adjacent driving teeth on the transmission gear ring 23 has sufficient insertion depth, so that the driving teeth on the first driving gear 18 can continue to move a distance into the tooth connection gap after being engaged with the transmission gear ring 23.

[0032] As a preferred implementation in this embodiment, a swivel is rotatably provided on the end of the L-shaped rod 19 extending to the inner cavity of the annular groove 21 .

[0033] The purpose is to reduce the friction between the L-shaped rod 19 and the annular groove 21 to prevent the L-shaped rod 19 from being seriously worn and affecting the movement accuracy of the cutting wheel 6.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
