[0002] A packing machine, also known as a bundling machine, a strapping machine or a tying machine, uses a strapping band to bundle products or packages, and then tightens and combines the two ends by means of hot melting bonding with a heating iron head. The function of the packing machine is to reinforce the packaged articles so that the articles will not fall apart due to insecure bundling during handling and storage, and at the same time, the bundling should be neat and beautiful.

[0003] The structure of the product blocking and limiting mechanism on the overall production line of the existing packing machine is simple. It is not convenient to adjust the position of the blocking mechanism according to the volume of different products, and the product cannot be blocked at the accurate position, which easily causes the situation of incomplete packing. Moreover, when packing both ends of the product, the product needs to move driven by a transmission device to align the unpacked part at the other end with the packing machine. However, after the product moves, it will continue to move backward due to its own inertia and cannot accurately move to the packing position, affecting the packing efficiency and quality. Summary of the Utility Model

The first servo motor is fixedly installed inside the leg frame, and its drive shaft is connected with a gear through a spline. The spur gear transmission rod is horizontally rotatably connected inside the leg frame and is in transmission connection with the gear on the drive shaft of the first servo motor through the transmission chain.

[0008] Preferably, the lateral movement mechanism includes a second servo motor and a spur gear. The second servo motor is vertically fixedly installed on one side of the upper surface of the moving plate close to the rack, and its output shaft passes through the lower part of the moving plate. The spur gear is connected to the drive shaft of the second servo motor through a spline and meshes with the rack.

[0009] Preferably, the lifting and blocking mechanism includes an electric lifting rod, a lifting and blocking block, a lifting flat plate, and a second slide rail.

Detailed implementation manner

[0022] Regarding the foregoing and other technical contents, features and effects of the present utility model, the following will cooperate with reference to the attached Figures 1 to 7 The embodiments are described in detail.

[0023] This embodiment provides a servo blocking roller line for a packing machine. As shown in the attached Figures 1-7 figure, it includes an outrigger frame 1 and an outer frame 2. A roller mechanism for driving the product to move is arranged at the top of the outrigger frame 1. The roller mechanism includes a first servo motor 4, a drive chain 5, a spur gear transmission rod 6, a belt 7 and a roller 8. The number of rollers 8 is several and several rollers 8 are evenly divided into two groups. The two groups of rollers 8 are respectively rotatably connected to both sides of the top of the outrigger frame 1 and adjacent rollers 8 are arranged in parallel. The top of the roller 8 is higher than the upper surface of the outrigger frame 1, which can ensure that only the bottom of the product contacts the roller 8, so that the roller 8 can drive the product to move. Adjacent rollers 8 on the same side are respectively connected by a belt 7. The first servo motor 4 is fixedly installed inside the outrigger frame 1 and the drive shaft is connected with a gear through a spline. The spur gear transmission rod 6 is horizontally rotatably connected inside the outrigger frame 1 and is in transmission connection with the gear on the drive shaft of the first servo motor 4 through the drive chain 5. One end of the spur gear transmission rod 6 away from the drive chain 5 is respectively connected to the two groups of rollers 8 through two belts 7; the first servo motor 4 drives the spur gear transmission rod 6 to rotate through the drive chain 5, and can drive the rollers 8 above it to rotate through the two belts 7 on the spur gear transmission rod 6. At the same time, adjacent rollers 8 are also connected by a belt 7, so that all the rollers 8 can rotate synchronously in the same direction, thereby playing the role of conveying the product.

[0024] The outer frame 2 is fixedly connected to the top of the outrigger frame 1 and a guiding mechanism is arranged in the middle of its top. The guiding mechanism includes a support rod 9, a first slide rail 10 and a rack 11. The number of support rods 9 is two and the two support rods 9 are arranged in parallel and fixedly connected to the middle of the top of the outer frame 2. The number of first slide rails 10 is two and the two first slide rails 10 are respectively fixedly installed on the upper surfaces of the two support rods 9. The two first slide rails 10 are on the same horizontal plane and are arranged in parallel. The rack 11 is fixedly connected to the side of one of the support rods 9 and is in transmission connection with the lateral moving mechanism;

[0025] A moving plate 3 is connected to the outside of the guiding mechanism in a lateral sliding manner. On both sides of the lower surface of the moving plate 3, sliding seats 18 are fixedly connected, and the two sliding seats 18 are respectively slidably connected to the outside of the two first sliding rails 10. A lateral moving mechanism for driving the lateral movement of the moving plate 3 is arranged on the side surface of the moving plate 3. The lateral moving mechanism includes a second servo motor 12 and a spur gear 13. The second servo motor 12 is vertically and fixedly installed on one side of the upper surface of the moving plate 3 close to the rack 11, and the output shaft penetrates below the moving plate 3. The spur gear 13 is connected to the driving shaft of the second servo motor 12 through a spline and meshes with the rack 11; the spur gear 13 is movably connected to the rack 11. The rack 11 is connected to the outer frame 2 and the leg support 1 as a relatively fixed whole, while the second servo motor 12 is fixed on the moving plate 3. The moving plate 3 can move on the first sliding rail 10 through the sliding seat 18. Therefore, when the second servo motor 12 drives the spur gear 13 to rotate, under the meshing action of the spur gear 13 and the rack 11, the moving plate 3 will move laterally on the first sliding rail 10 through the sliding seat 18, thereby driving the lifting and blocking mechanism to move laterally.

[0026] An elevating and blocking mechanism for blocking the product is arranged in the middle of the same side of the moving plate 3 as the lateral moving mechanism. The elevating and blocking mechanism includes an electric elevating rod 14, an elevating and blocking block 15, an elevating flat plate 16 and a second sliding rail 17. The fixed rod body of the electric elevating rod 14 is fixedly installed in the middle of the side of the moving plate 3 close to the lateral moving mechanism, and the end of the movable rod body is fixedly connected to the elevating and blocking block 15. The elevating and blocking block 15 is horizontally arranged. The number of the elevating flat plates 16 is two, and the two elevating flat plates 16 are respectively vertically and fixedly connected to both sides of the upper surface of the elevating and blocking block 15. The sides of the elevating and blocking block 15 and the elevating flat plates 16 close to the product are all in the same vertical plane. Second sliding rails 17 are fixedly connected to the sides of the two elevating and blocking blocks 15. Sliding seats 18 adapted to the second sliding rails 17 are fixedly connected to both ends of the side of the moving plate 3 away from the lateral moving mechanism. The two second sliding rails 17 are vertically slidably connected in the sliding seats 18 on both sides; the electric elevating rod 14 can drive the elevating and blocking block 15 to move up and down, and the second sliding rail 17 can vertically slide in the sliding seat 18, which can strengthen and limit the movement of the elevating and blocking block 15 and improve the blocking force of the elevating and blocking block 15.

[0027] Sensor assemblies are arranged in the middle of the bottom end of the moving plate 3 and the middle of the upper surface of the leg support 1. The sensor assemblies include a first laser sensor 19, a second laser sensor 20 and a third laser sensor 21. The first laser sensor 19 is fixedly installed in the middle of the bottom end of the moving plate 3, and the second laser sensor 20 and the third laser sensor 21 are respectively fixedly installed on both sides of the middle of the top end of the leg support 1.

[0028] One end of the outrigger frame 1 close to the lifting flat plate 16 is the product feeding end. The first laser sensor 19 is arranged on one side of the bottom end of the moving plate 3 close to the product feeding end, and the horizontal distance between the first laser sensor 19 and the product feeding end is less than the horizontal distance between the lifting stop block 15 and the product feeding end. The first laser sensor 19 can sense the product entering from the product feeding end, so as to know the height of the product, and then the control unit controls the movable rod body of the electric lifting rod 14 to extend an appropriate length, so that the lifting stop block 15 can correspond to the middle part of the side of the product to effectively block the product; The second laser sensor 20 and the third laser sensor 21 are respectively fixedly installed on one side of the upper surface of the outrigger frame 1 close to the product feeding end and far from the product feeding end.

[0029] When the product moves onto the second laser sensor 20 on the side close to the product feeding end, after the second laser sensor 20 senses the product, the control unit controls the roller mechanism to stop. At the same time, the electric lifting rod 14 drives the lifting stop block 15 to move down to block the product, and then the external bundling machine bundles one end of the product close to the lifting stop block 15; After the bundling is completed, the roller mechanism drives the product to move backward, and at the same time, the transverse moving mechanism drives the lifting blocking mechanism to move synchronously with the product. The lifting stop block 15 always fits with the product. When the product moves onto the third laser sensor 21, the roller mechanism and the transverse moving mechanism are stopped. The lifting stop block 15 can prevent the product from continuing to move backward due to inertial buffering, ensuring that the product can be in the accurate bundling position, and then the bundling machine bundles the end of the product far from the lifting stop block 15, so that both ends of the product are bundled. Then the lifting stop block 15 is retracted, and the roller mechanism drives the bundled product to continue to move backward to the next process, while the lifting blocking mechanism returns to the initial position under the drive of the transverse moving mechanism to perform the bundling work of the next product.

[0030] The first servo motor 4, the second servo motor 12, the electric lifting rod 14, the first laser sensor 19, the second laser sensor 20 and the third laser sensor 21 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0031] To sum up, the using steps of the servo blocking roller line of this bundling machine are as follows:

[0032] 1. When the product moves onto the second laser sensor 20 on the side close to the product feeding end, after the second laser sensor 20 senses the product, the control unit controls the roller mechanism to stop. At the same time, the electric lifting rod 14 drives the lifting stop block 15 to move down to block the product, and then the external bundling machine bundles one end of the product close to the lifting stop block 15;

[0033] 2. After the packing is completed, the roller mechanism drives the product to move backward. At the same time, the lateral movement mechanism drives the lifting and blocking mechanism to move synchronously with the product. The lifting and blocking block 15 always fits with the product. When the product moves onto the third laser sensor 21, the roller mechanism and the lateral movement mechanism are stopped. The lifting and blocking block 15 can prevent the product from continuing to move backward due to inertial buffering, ensuring that the product can be in the accurate packing position.

[0034] 3. Then, the packing machine packs one end of the product away from the lifting and blocking block 15, thus completing the packing of both ends of the product. Then, the lifting and blocking block 15 is retracted, and the roller mechanism drives the packed product to continue moving backward to the next process. The lifting and blocking mechanism returns to the initial position under the drive of the lateral movement mechanism to perform the packing work for the next product.

[0035] The above description is only for the purpose of illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various equivalent forms that conform to the idea of the present invention are within the protection scope of the present invention.
