[0003] At present, when making sample cards, the whole roll of aluminum strip is first cut into equal lengths using a cutting device, and then the cut aluminum strips are collected. After the aluminum strips are collected, they are transferred to a marking station, and the marking mechanism is used to mark them one by one to finally obtain a sample card with a logo. However, when producing sample cards in this way, on the one hand, the production of sample cards requires the cooperation of two separately set mechanisms, which increases the production cost due to the increase in equipment, and the use of two stations to complete the work requires a large area; on the other hand, it takes a certain amount of time for the aluminum strip to be transferred to the marking station after cutting, which affects the production efficiency of the sample cards per unit time.

[0004] Therefore, there is an urgent need for a fully automatic high-speed marking and cutting sample card mechanism to reduce the sample card production cost and improve production efficiency. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a fully automatic high-speed marking and cutting sample card mechanism, which is used to solve the problems of low production efficiency and high production cost caused by the separate setting of marking station and cutting station in the existing sample card production.

[0013] Furthermore, the feeding unit also includes a cache slot, and the cache slot is arranged between the first driving wheel and the second driving wheel through a mounting plate.

[0014] Furthermore, the cache slot is located in a tangential direction between the first driving wheel and the corresponding driven wheel.

[0015] Furthermore, a proximity switch is provided at the bottom of one end of the cache slot away from the first driving wheel, and the proximity switch is mounted on the frame.

When the buffer length is insufficient, the first feeding motor and the second feeding motor continue to feed the strip. When the proximity switch detects that there is aluminum strip at this position, the feeding is stopped to prevent the aluminum strip in the buffer slot from being too knotted.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] See attached Figure 1 , shown is a sample card 1 made of aluminum material. During production, the sample card 1 needs to be marked with a marking area 2 on one side using a marking machine, and then a fixing hole 3 is processed at one end, and finally the sample card is cut to equal length.

[0036] See attached Figure 2-5 , shown is a fully automatic high-speed marking and cutting sample card mechanism, including a frame 4, a material shaft 5 is rotatably provided on the frame 4, the material shaft 5 is used to set up the aluminum coil 36, and a feeding unit 6, a marking unit 7 and a cutting unit 8 are sequentially provided on the top of the frame 4;

[0037] The feeding unit 6 includes a mounting plate 9, which is fixed to the frame 4 by bolts or welding. A first feeding motor 11 and a second feeding motor 12 are provided on one side of the mounting plate 9, and the second feeding motor 12 is located above the first feeding motor 11. The output ends of the first feeding motor 11 and the second feeding motor 12 are located on the other side of the mounting plate 9 and are respectively provided with a first driving wheel 13 and a second driving wheel 14. At the same time, a driven wheel 15 is provided on the mounting plate 9 for cooperating with the first driving wheel 13 and the second driving wheel 14 to clamp the aluminum strip. When the sample card 1 is produced, the aluminum coil 36 is mounted on the material shaft 5, and then the aluminum strip on the aluminum coil 36 is passed through the first driving wheel 13 and the driven wheel 15 in turn, and then passed out from between the second driving wheel 14 and the corresponding driven wheel 15. The first feeding motor 11 and the second feeding motor 12 drive the first driving wheel 13 and the second driving wheel 14 to rotate, and cooperate with the driven wheel 15 to realize feeding by friction to enable the aluminum strip to move.

[0038] At the same time, the feeding unit 6 also includes two guide wheel groups, which are respectively arranged at the feeding front ends of the first driving wheel 13 and the second driving wheel 14 through the mounting plate 9, wherein the guide wheel group includes a pressing wheel 16 rotatably arranged on the mounting plate 9 and a limiting wheel 17 rotatably arranged below the pressing wheel 16, wherein limiting plates 18 are arranged at both ends of the limiting wheel 17, and the pressing wheel 16 is located between the two limiting plates 18. When in use, the aluminum strip is placed between the pressing wheel 16 and the limiting wheel 17, and the aluminum strip is limited by the limiting plates 18 at both ends of the limiting wheel 17 to prevent the aluminum strip from deviating during walking;

[0039] At the same time, the feeding unit 6 includes a buffer slot 28 installed between the first driving wheel 13 and the second driving wheel 14 through a connecting bracket. The buffer slot 28 is specifically arranged in the tangent direction of the first driving wheel 13 and the corresponding driven wheel 15, so that the aluminum strip from the first driving wheel 13 will not tilt upward or downward. At the same time, the buffer slot 28 can cache a certain length of the aluminum strip between the first driving wheel 13 and the second driving wheel 14 to reduce the tension of the aluminum strip between the first driving wheel 13 and the second driving wheel 14 to prevent pulling and deformation;

[0040] At the same time, in order to ensure the buffer length of the aluminum strip in the buffer slot 28, a proximity switch 29 is provided on the frame 4 below the buffer slot 28, and a sensing hole is provided at the position of the buffer slot 28 corresponding to the proximity switch 29, so that when the proximity switch 29 detects that there is an aluminum strip in the upper buffer slot 28 through the sensing hole, the first feeding motor 11 and the second feeding motor 12 stop feeding, and continue feeding when no aluminum strip is detected;

[0041] See attached Figure 6 , the frame 4 is provided with a marking unit 7 and a cutting unit 8 through a supporting arm 10, wherein the marking unit 7 is located between the second driving wheel 14 and the cutting unit 8, and the marking unit 7 includes a laser marking machine 20 for marking the marking area 2 of the sample card 1, and the aluminum strip is marked by the laser marking machine 20;

[0042] See attached Figure 6As shown, the support arm 10 is also provided with a cutting unit 8, and the cutting unit 8 includes a driving cylinder 21, and the driving cylinder 21 is specifically a double-headed cylinder, wherein the output end of the driving cylinder 21 is provided with a punch 24 for processing the fixing hole 3 of the sample card 1 and a cutter 23 for cutting the aluminum strip, and at the same time, a fixed mold 22 is provided on the mounting plate 9 below the cutter 23, and the fixed mold 22 is provided with a punch 26 and a knife edge 25 corresponding to the positions of the punch 24 and the cutter 23, and at the same time, the fixed mold 22 is provided with a feed port 27 through the running direction of the aluminum strip, and the opening direction of the feed port 27 intersects and is perpendicular to the opening direction of the knife edge 25 and the punch 26. When in use, the aluminum strip is introduced into the fixed mold 22 through the feed port 27, and then the driving cylinder 21 is started to drive the punch 24 and the cutter 23 to complete the processing and cutting of the fixing hole 3 through the punch 26 and the knife edge 25 to obtain the sample card 1;

[0043] See attached Figure 3 , Attachment Figure 7 , as shown, a brake disc 34 is provided at one end of the material shaft 5 located in the frame 4, and a brake mechanism is provided at the position of the brake disc 34 of the frame 4. The brake mechanism includes a force-bearing plate 30 fixedly arranged on the side wall of the frame 4, and a brake spring 32 is provided on the side of the force-bearing plate 30 close to the brake disc 34. The other end of the brake spring 32 is connected to a brake block 31, and guide rods 33 are provided at both ends of the brake block 31. At the same time, a guide hole 35 is opened at the position of the guide rod 33 of the force-bearing plate 30. When in use, the brake spring 32 acts on the brake block 31 to generate friction on the brake disc 34 to achieve braking of the entire aluminum coil 36, thereby preventing the aluminum coil 36 from freely rotating when unwinding and causing the aluminum strip to accumulate and bend;

[0044] It should be noted that the friction force of the brake spring 32 acting on the brake disc 34 through the brake block 31 is smaller than the traction force of the first drive wheel 13 and the second drive wheel 14 on the aluminum strip, thereby ensuring that the aluminum coil 36 can be pulled when feeding, and the aluminum coil 36 can be braked by the brake mechanism when feeding stops.

[0045] In summary, the feeding unit 6, marking unit 7 and cutting unit 8 are integrated through the frame 4, replacing the original production method of arranging marking and cutting in a dispersed manner. On the one hand, the floor space is reduced, and at the same time, the structure of the sample card 1 production equipment is reduced through the integrated arrangement, thereby reducing the production cost and reducing the transfer time of the aluminum strip between the marking and cutting processes, thereby improving the production efficiency.

[0046] See attached Figure 8, as shown in the figure, when in use, the aluminum coil 36 is first mounted on the frame 4 through the material shaft 5, and then the aluminum strip on the aluminum coil 36 is passed through the pressure wheel 16 and the limit wheel 17, the first driving wheel 13, the second driving wheel 14 and the corresponding driven wheels 15 in sequence and passes through the feed port 27 of the fixed mold 22, and then the driving cylinder 21 is started to drive the punch needle 24 and the cutter 23 to move downward to complete the punching and shearing of the end of the first sample card 1, and then the first feeding motor 11 and the second feeding motor 12 drive the first driving wheel 13 and the second driving wheel 14 to continue punching and shearing the aluminum strip. Continue feeding. When the length of the aluminum strip passing through the cutter 23 reaches the set length, the first feeding motor 11 and the second feeding motor 12 stop feeding, and then the driving cylinder 21 drives the punch 24 and the cutter 23 to move again. At this time, the cutter 23 is used to cut the aluminum strip to obtain the first sample card 1, and the punch 24 is used to complete the processing of the fixing hole 3 at one end of the second sample card 1. In this way, the automatic feeding and cutting of the aluminum strip are completed through the alternating actions of the first feeding motor 11, the second feeding motor 12 and the driving cylinder 21, and the continuous production of the sample card 1 is realized;

[0047] See attached Fig. 9 As shown in the figure, in order to prevent the sample card 1 ejected from the fixed mold 22 from being rolled into the raw material below when falling, the utility model has a material box 37 for collecting sample cards welded and fixed below the fixed mold 22 through a mounting plate. One end of the material box 37 is inclined. When the sample card 1 falls into the material box 37, it slides down to the bottom of the material box 37 under the action of the slope. This not only achieves the purpose of collecting the sample card 1, but also avoids the accumulation of sample cards below the fixed mold 22.

[0048] The above description is only a preferred specific implementation method of the present utility model, and does not limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
