DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present application in detail Figure 1-2 with reference to the accompanying drawings.

[0020] An embodiment of the present application discloses a laser tearing mechanism.

[0021] Referring to Figure 1 and Figure 2 , the laser tearing mechanism includes a bottom frame 1. In the embodiment of the present application, the bottom frame 1 is composed of an aluminum alloy frame. A conveying unit for conveying the product and a cutting unit for cutting the plastic bag of the product are provided on the bottom frame 1. The conveying unit includes a first conveyor 2 and a second conveyor 3 arranged side by side on the bottom frame 1. A shunting unit for shunting and conveying the product to the first conveyor 2 or the second conveyor 3 is provided at the input end of the conveying unit. A receiving box 25 is placed at the output end of the conveying unit. The receiving box 25 is located at the output ends of the first conveyor 2 and the second conveyor 3. The receiving box 25 is used to conveniently collect the products after tearing, improving the cleanliness of the production line.

[0022] Therefore, after the shunt unit conveys the products to the first conveyor 2 or the second conveyor 3, the cutting unit is started to cut the plastic bags of the products, realizing the tearing of the plastic bags of the products. The conveying unit is used to continuously feed the products, improving the production continuity, reducing the labor cost, saving time and effort, and at the same time improving the efficiency of tearing the plastic bag packages of the products.

[0023] Referring to Figure 1 and Figure 2 , the shunt unit includes a third conveyor 4 arranged on the bottom frame 1. In the embodiment of the present application, the output end of the third conveyor 4 corresponds to the input ends of the first conveyor 2 and the second conveyor 3 at the same time. The width dimension of the third conveyor 4 is equal to the sum of the width dimensions of the first conveyor 2 and the second conveyor 3. Oppositely arranged first guide plate 9 and second guide plate 10 are respectively bolted on the third conveyor 4. The first guide plate 9 and the second guide plate 10 play a limiting role on the products on the third conveyor 4. In addition, in the embodiment of the present application, both ends of the first guide plate 9 and the second guide plate 10 are open, which is convenient for guiding the products on the third conveyor 4, reducing the possibility of the products breaking out of the third conveyor 4 and facilitating the subsequent shunting operation of the products.

[0024] Referring to Figure 1 and Figure 2 , a first shunt plate 6 is rotatably connected to the surface of the first guide plate 9 facing the second guide plate 10, and a second shunt plate 7 is rotatably connected to the surface of the second guide plate 10 facing the first guide plate 9. The products are located between the first shunt plate 6 and the second shunt plate 7. A connecting seat 14 is installed at one end of the first shunt plate 6, and a connecting shaft is installed on the first guide plate 9. The connecting seat 14 and the connecting shaft are rotatably connected through a bearing. Therefore, the friction between the first shunt plate 6 and the connecting shaft is reduced through the bearing, and at the same time, the first shunt plate 6 is supported and positioned, enabling it to rotate smoothly around the connecting shaft. The bearing structure can also be correspondingly arranged between the second guide plate 10 and the second shunt plate 7 with reference to the first guide plate 9.

[0025] Referring to Figure 1 and Figure 2 , a shunt channel 8 is formed between the first shunt plate 6 and the second guide plate 10. A driving component for controlling the shunt channel 8 to communicate with the first conveyor 2 or the second conveyor 3 is arranged on the third conveyor 4. The driving component includes a mounting plate 11 bolted between the first guide plate 9 and the second guide plate 10. A telescopic cylinder 12 is rotatably connected to the mounting plate 11. A connecting rod 13 is installed between the first shunt plate 6 and the second shunt plate 7, and the connecting rod 13 is arranged at the output end of the telescopic cylinder 12.

[0026] Therefore, the telescopic cylinder 12 is activated to drive the connecting rod 13 at the output end of the telescopic cylinder 12 to move. While the connecting rod 13 is moving, it drives the first diverter plate 6 and the second diverter plate 7 to move synchronously. When the telescopic cylinder 12 retracts, the diversion channel 8 communicates with the first conveyor 2, and the product is conveyed along the third conveyor 4 to the first conveyor 2; when the telescopic cylinder 12 extends, the diversion channel 8 communicates with the second conveyor 3, and the product is conveyed along the third conveyor 4 to the second conveyor 3, thereby realizing the control of the communication between the diversion channel 8 and the first conveyor 2 or the second conveyor 3.

[0027] Refer to Figure 1 and Figure 2 , two relatively arranged first limit plates 21 are bolted to the first conveyor 2. A first conveying channel 22 is formed between the two first limit plates 21. The two first limit plates 21 limit the position of the product on the first conveyor 2, reducing the possibility of the product deviating from the first conveyor 2. Two relatively arranged second limit plates 23 are bolted to the second conveyor 3. The two second limit plates 23 limit the position of the product on the second conveyor 3. A second conveying channel 24 is formed between the two second limit plates 23, reducing the possibility of the product deviating from the second conveyor 3.

[0028] Therefore, when the telescopic cylinder 12 retracts, the diversion channel 8 communicates with the first conveying channel 22; when the telescopic cylinder 12 extends, the diversion channel 8 communicates with the second conveying channel 24, thereby realizing the control of the communication between the diversion channel 8 and the first conveyor 2 or the second conveyor 3, enabling the diversion of the products on the third conveyor 4, facilitating the classification and slitting treatment of products of different models, and also being able to flexibly adjust the transportation volume of products according to actual production requirements. If a product blockage occurs on the first conveyor 2 within the conveying unit, the products can be diverted to the second conveyor 3 through the diversion unit to ensure the smooth operation of the overall laser slitting mechanism. The existence of the diversion unit makes the entire conveying system more flexible and variable, capable of adapting to changes in different production scenarios and requirements, and improving production efficiency.

[0029] Refer to Figure 1 and Figure 2 , one end of each of the two first limit plates 21 facing the third conveyor 4 is fixedly connected with a guide plate 5, and one end of each of the two guide plates 5 facing the third conveyor 4 partially extends onto the third conveyor 4; when the diversion channel 8 communicates with the first conveying channel 22, the two guide plates 5 are respectively aligned with the first diverter plate 6 and the second diverter plate 7. Therefore, the guide plates 5 play a guiding role in the position of product conveyance, reducing the possibility of product position deviation when being conveyed from the third conveyor 4 to the first conveyor 2 and improving the stability of product conveyance.

[0030] Refer to Figure 1 and Figure 2A compacting unit for pressing the product is arranged between the third conveyor 4 and the mounting frame 15, and the compacting unit includes a support frame 18 arranged on the bottom frame 1, and two support rods 19 are rotatably connected to the support frame 18, and the ends of the two support rods 19 facing away from the support frame 18 are rotatably connected to rollers 20, respectively. The two support rods 19 correspond to the first conveyor 2 and the second conveyor 3 respectively, and the product passing through the rollers 20 is pressed between the first conveyor 2 or the second conveyor (3).

[0031] Therefore, when the product is conveyed to the bottom of the roller 20, the gravity of the roller 20 is used to squeeze the surface of the product made of wood chip material, so that the product is pressed flat, which facilitates the uniformity of the tear when the plastic bag of the product is subsequently cut and torn.

[0032] Reference Figure 1 and Figure 2 The cutting unit includes two mounting frames 15 arranged on the bottom frame 1, and the two mounting frames 15 are respectively slidably connected with laser marking machines 16, and the laser ends of the two laser marking machines 16 correspond to the first conveyor 2 and the second conveyor 3 respectively, and the laser end of one laser marking machine 16 is located directly above the conveyor belt of the first conveyor 2, and the laser end of the other laser marking machine 16 is located directly above the conveyor belt of the second conveyor 3. The two mounting frames 15 are respectively provided with lifting components for driving the laser marking machines 16 to rise and fall, and the lifting components include a linear module 17 arranged on the mounting frame 15. The linear module 17 in the embodiment of the present application specifically adopts a slide linear module 17, and the laser marking machine 16 is arranged on the slide of the linear module 17.

[0033] Therefore, the linear module 17 is started to drive the slide of the linear module 17 to rise and fall, so that the height of the laser marking machine 16 can be adjusted, which is convenient for adjusting the distance between the laser end of the laser marking machine 16 and the product, and has greater flexibility. When the product is transported to the bottom of the laser end of the laser marking machine 16, the laser marking machine 16 is started to cut and tear the plastic bag on the surface of the product, so as to facilitate the subsequent tearing of the package to take out the product.

[0034] The implementation principle of the embodiment of the present application is as follows: the third conveyor 4 is started, the product is conveyed along the third conveyor 4, the telescopic cylinder 12 is started, and the connecting rod 13 at the output end of the telescopic cylinder 12 is driven to move, and the connecting rod 13 drives the first diverter plate 6 and the second diverter plate 7 to move synchronously while moving. When the telescopic cylinder 12 is retracted, the diverter channel 8 is communicated with the first conveyor 2, and the product is conveyed to the first conveyor 2 along the third conveyor 4; when the telescopic cylinder 12 is extended, the diverter channel 8 is communicated with the second conveyor 3, and the product is conveyed to the second conveyor 3 along the third conveyor 4, thereby realizing the diversion of the product on the third conveyor 4;

[0035] When the shunted product is conveyed below the roller 20, the gravity of the roller 20 is used to extrude the product made of wood chip materials, so that the surface of the product is pressed flat, facilitating the uniformity of the tear when cutting and tearing the plastic bag of the product subsequently; when the product is conveyed directly below the laser end of the laser marking machine 16, the laser marking machine 16 is started to cut the plastic bag on the surface of the product to form a tear, thus facilitating the subsequent tearing of the package to take out the product. The use of the conveying unit realizes continuous feeding of the product, improves production continuity, reduces labor costs, saves time and effort, and at the same time improves the efficiency of tearing the plastic bag packaging of the product.

[0036] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
