DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0028] Example:

[0029] like Figure 1 to Figure 7 As shown, the present invention provides an automatic sampling device for thermal film, comprising a frame 1 and a cutting component 2, a pushing component 3 and a moving component 4 installed on the frame 1, the frame 1 is welded by 50*50 square tubes, the cutting component 2 is located above the pushing component 3, the cutting component 2 is used to cut the thermal film 6, the pushing component 3 is used to further cut off the thermal film 6, a receiving component 5 is arranged on the side of the cutting component 2, the receiving component 5 is used to receive the cut thermal film 6, and the moving component 4 is used to drive the cutting component 2 and the pushing component 3 to move synchronously.

[0030] Furthermore, the cutting component 2 includes a cylinder 1 21, a cylinder 22, a cutting knife 23 and an upper push rubber plate 24. The cylinder 1 21 is fixedly mounted on a base plate 25, and the base plate 25 is connected to the moving component 4. The output end of the cylinder 1 21 is fixedly connected to a knife seat 26 via a mounting plate 27. The cutting knife 23 is fixedly mounted on the bottom of the knife seat 26. The cylinder body of the cylinder 22 is fixedly mounted on the knife seat 26, and its output end passes through the knife seat 26 and is fixedly connected to the upper push rubber plate 24 arranged in the cutting knife 23. The cutting knife 23 is cylindrical, and the diameter of the upper push rubber plate 24 is smaller than the inner hole diameter of the cutting knife 23.

[0031] Furthermore, a guide rod 8 is fixedly mounted on the mounting plate 27 , and the guide rod 8 can play a good vertical guiding role, so that the cutting knife 23 corresponds to the position of the push-down rubber disc 32 , which is convenient for better cutting of the thermal adhesive film 6 .

[0032] Furthermore, the pushing component 3 includes a cylinder three 31, a push-down rubber disc 32 and a nylon plate 33. The cylinder body of the cylinder three 31 is fixedly mounted on a mounting seat 34 and connected to the moving component 4. The output end of the cylinder three 31 is fixedly connected to the push-down rubber disc 32. The nylon plate 33 is fixedly mounted on the top of the mounting seat 34. The nylon plate 33 is used mainly because the nylon plate 33 has a low friction coefficient and is non-sticky, which is convenient for the transmission and cutting of the hot rubber sheet 6. The push-down rubber disc 32 passes through the nylon plate 33 to push the hot rubber sheet 6 into the cutting knife 23. During cutting, the push-down rubber disc 32 and the nylon plate 33 are located on the same plane, which is convenient for cutting.

[0033] Furthermore, the receiving component 5 includes a cylinder four 51, a guide pair 52 and a tray 53. The cylinder body of the cylinder four 51 is fixedly mounted on the frame 1. The guide pair 52 includes a guide rail 521 and a slider 522. There are two sliders 522 in this embodiment. The two sliders 522 are connected by a connecting rod 54, so that the two sliders 522 move synchronously under the push of the cylinder four 51. The output end of the cylinder four 51 is connected to one of the sliders 522 through a connecting plate 55. A tray 53 is fixedly mounted on the other slider 522. The tray 53 is used to receive the cut thermal film 6.

[0034] When in use, the output end of the cylinder 24 51 pushes the slider 1 522 to slide along the guide rail 1 521. Since the two sliders 1 522 are connected by the connecting rod 54, the sliding of one slider 1 522 synchronously drives the sliding of the other slider 1 522. The tray 53 is installed on the slider 1 522 far away from the output end of the cylinder 24 51, thereby increasing the distance between the cutting knife 23 and the tray 53, and does not affect the cutting and sampling work.

[0035] Furthermore, the moving component 4 includes a driving component 41 and a translation component 42 , the cutting component 2 and the pushing component 3 are both connected to the translation component 42 , and the driving component 41 is used to drive the translation component 42 to move horizontally.

[0036] Furthermore, the driving component 41 includes a motor 411, a driving wheel 412, a driving belt 413 and a transmission shaft 414, the motor 411 is fixedly mounted on the frame 1, the driving wheel 412 includes a driving wheel 1 4121, a driving wheel 2 4122, a driving wheel 3 4123 and a driving wheel 4 4124, the driving belt 413 includes a driving belt 1 4131 and a driving belt 2 4132, the transmission shaft 414 is fixedly mounted on the frame 1 through a seat bearing 9, the transmission shaft 414 includes a transmission shaft 1 4141 and a transmission shaft 2 4142, the outer end of the transmission shaft 1 4141 is coaxially fixedly mounted with a driving wheel 1 4121 and a driving wheel 4 4124, and the driving wheel 1 4121 is located on the outside of the driving wheel 4 4124.

[0037] Further, the translation component 42 includes a guide rail pair 2 421, a guide rail pair 3 422, a rotating wheel 423, a translation belt 424 and a pressure plate 425, the guide rail pair 2 421 includes a guide rail 2 4211 and a slider 2 4212, the guide rail pair 3 422 includes a guide rail 3 4221 and a slider 3 4222, the rotating wheel 423 includes a rotating wheel 1 4231, a rotating wheel 2 4232, a rotating wheel 3 4233 and a rotating wheel 4234, the translation belt 424 includes a translation belt 1 4241 and a translation belt 2 4242, the bottom plate 25 and the mounting seat 34 are respectively fixedly connected to the slider 2 4212 of the guide rail pair 2 421 and the slider 3 4222 of the guide rail pair 3 422, and the slider 2 4212 slides with the guide rail 2 4211 The slider three 4222 is slidably connected with the guide rail three 4221, the pressure plate 425 is fixedly installed on the base plate 25 and the cylinder three 31, the transmission shaft one 4141 drives the wheel one 4231 fixedly installed thereon to rotate, the wheel one 4231 drives the wheel two 4232 fixedly installed on the rotating shaft one 10 to rotate synchronously through the translation belt one 4241, the transmission shaft two 4142 drives the wheel three 4233 fixedly installed thereon to rotate, the wheel three 4233 drives the wheel four 4234 fixedly installed on the rotating shaft two 11 to rotate through the translation belt two 4242, the rotating shaft one 10 and the rotating shaft two 11 are fixedly installed on the frame 1 through the belt seat bearing 9, and the pressure plate 425 is fixedly installed on the translation belt 424.

[0038] When it is necessary to synchronously move the cutting component 2 and the pushing component 3 horizontally, the motor 411 is started to drive the driving wheel three 4123 to rotate, and under the action of the driving belt two 4132, the driving wheel four 4124 on the transmission shaft one 4141 is synchronously driven to rotate, and the rotation of the driving wheel four 4124 drives the rotation of the driving wheel one 4121, and under the action of the driving belt one 4131, the rotation of the driving wheel one 4121 drives the rotation of the driving wheel two 4122, and then drives the transmission shaft two 4142 to rotate, so that the transmission shaft one 4141 and the transmission shaft two 4142 move synchronously, and the rotation of the transmission shaft one 4141 drives the rotation of the rotating wheel one 4231, and under the action of the translation belt one 4241, the rotating wheel two 4232 is driven to rotate, so that the translation belt one 4241 moves along the rotating wheel one 4231 and the rotating wheel two 4232. Pressing plates 425 are fixedly installed on both sides of the bottom plate 25, and the pressing plates 425 are fixedly installed on both sides of the bottom plate 25. The plate 425 is fixedly installed on the corresponding translation belt 1 4241 by means of screws or the like, so that the translation belt 1 4241 drives the cutting knife 23 to move horizontally along the guide rail 2 4211, thereby completing the horizontal movement of the cutting assembly 2. Similarly, the transmission shaft 2 4142 drives the rotating wheel 3 4233 to rotate, and under the action of the translation belt 2 4242, it drives the rotating wheel 4234 to move, so that the translation belt 2 4242 moves along the rotating wheel 3 4233 and the rotating wheel 4 4234. A pressing plate 425 is fixedly installed on the bottom of the cylinder 3 31. The pressing plate 425 is fixedly installed on the translation belt 2 4242 by means of screws or the like, so that the translation belt 2 4242 drives the push-down rubber disc 32 to move horizontally along the guide rail 3 4221. At this point, the synchronous horizontal movement of the pushing assembly 3 and the cutting assembly 2 is completed, ensuring the linearity and accuracy of the movement, and improving the stability and reliability of the equipment.

[0039] Furthermore, the contact surface between the pressing plate 425 and the translation belt 424 is toothed, which increases the friction between the pressing plate 425 and the translation belt 424, improves the fixing effect, and helps the cutting component 2 and the pushing component 3 to move horizontally smoothly.

[0040] Furthermore, the motor 411 is a servo motor. By adjusting the parameters of the servo motor, the cutting assembly 2 and the pushing assembly 3 can be synchronized with the hot film 6 to automatically take the film without stopping the machine, and the moving speed of the cutting assembly 2 and the pushing assembly 3 can be accurately controlled, thereby improving the flexibility of the equipment. The transmission method between the driving wheel 412 and the driving belt 413, the rotating wheel 423 and the translation belt 424 can be a sprocket chain transmission, or a pulley belt rotation, but it is not limited to the above transmission methods. As long as the transmission method of the present application can be realized, it belongs to the protection scope of the present application.

[0041] Furthermore, rollers 7 are installed on the frame 1 on both sides of the pushing component 3, and the rollers 7 are used to convey the thermal adhesive 6.

[0042] Here’s how it works:

[0043] When the hot rubber sheet 6 moves forward on the roller 7, the cutter cylinder 1 21 drives the cutting knife 23 to punch and cut the hot rubber sheet 6 downward and press it against the nylon plate 33. To prevent the hot rubber sheet 6 from being partially not cut thoroughly, the next step is to start the push-down glue cylinder 31 to drive the push-down glue plate 32 to move upward and push the cut hot rubber sheet 6 into the inner hole of the cutting knife 23. The next step is to lift the cutter cylinder 1 21 into place, push the push-pull cylinder 4 51, and push the tray 53 to the bottom of the cutting knife 23 through the joint action of the guide rail pair 1 52, the connecting plate 55 and the connecting rod 54. The next step is to start the cylinder 22 to drive the push-up glue plate 24 downward to push the hot rubber sheet 6 in the cutting knife 23 into the tray 53. Finally, the tray 53 returns to its original position driven by the push-pull cylinder 4 51 and waits for the next cycle.

[0044] In addition, when the hot glue sheet 6 is moving forward, when the cutter cylinder 1 21 drives the cutter 23 to punch down the hot glue sheet 6 and press it against the nylon plate 33, in the next step, the servo motor 411 drives the cutting component 2 and the pushing component 3 to move synchronously with the hot glue sheet 6 in the same direction and at the same speed through the driving wheel 412, the driving belt 413, the transmission shaft 414 and other components, so that the hot glue sheet sample can be quickly cut in an online non-stop state. When the cut hot glue sheet 6 sample is in the inner hole of the cutter 23 and rises with the cutter cylinder 1 21, in the next step, the servo motor 411 starts to reverse and drives the cutting component 2 and the pushing component 3 to synchronously return to the original position to wait for the next cycle to start.

[0045] The present application can realize the rapid cutting of thermal films with different hardness and viscosity by cooperating with each other between different components.
