Description

Technical Field

[0001] This invention relates to the field of baling machine technology, specifically a semi-automatic plastic strapping machine. Background Technology

[0002] In modern industrial assembly line production, after the goods are processed, they need to be stacked, transferred, and stored. To prevent the goods from scattering, tipping, or being damaged by collisions during stacking and transportation, bundling and securing the goods is a core process to ensure the safety of logistics flow. Currently, the commonly used bundling materials in the industrial field are mainly divided into two categories: one is the woven strapping that is more widely used in China, and the other is PET plastic steel strapping that is widely used in the international market. Among them, plastic steel strapping has gradually become the mainstream material for standardized bundling on assembly lines due to its high tensile strength, wear resistance, good toughness, environmental friendliness, recyclability, and suitability for bundling heavy goods.

[0003] Currently, most plastic strapping operations rely on manual packaging, which is not only cumbersome and time-consuming, significantly reducing overall production efficiency, but also requires a large amount of manual labor, increasing labor costs and workers' workload. In addition, manual step-by-step operations are prone to errors, resulting in deviations in strapping positions and misplacement of pallets, affecting stacking stability. Furthermore, the independent operation mode is not compatible with the rhythm of continuous production on the assembly line, which can easily cause production line congestion and stoppages.

[0004] To address the above issues, a semi-automatic plastic strapping machine is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a semi-automatic plastic strapping machine. By using this invention, the problems of the current plastic strapping operations, which mostly rely on manual packaging, are solved. This increases labor costs and the labor intensity of workers, and also easily leads to deviations in strapping position and misplacement of pallets, affecting the stability of stacking.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A semi-automatic plastic strapping machine includes a frame with a first crossbeam inside.

[0009] Furthermore, the clamping assembly includes a third cylinder fixedly connected to one side of the second crossbeam, and a pressure block is fixedly connected to the movable end of the third cylinder, the pressure block being in accordance with the shape of the guide groove.

[0010] Furthermore, the tape take-up assembly includes a motor installed on one side of the sliding frame. The output end of the motor is fixedly connected to a first rotating shaft, and a second rotating shaft is rotatably connected inside the sliding frame. Both the outer walls of the first and second rotating shafts are fixedly connected to sprockets, and the two sprockets are connected by chain drive. One end of the second rotating shaft has a tape take-up groove.

[0011] Furthermore, the translation component includes a threaded rod threadedly connected to the limiting seat, a movable seat rotatably connected to one end of the threaded rod, two guide rods fixedly connected in parallel to one side of the movable seat, both guide rods being slidably connected to the limiting seat, a dual-axis motor installed inside the movable seat, and the threaded rod being fixedly connected to one output shaft of the dual-axis motor.

[0012] Furthermore, the rotating assembly includes a rotating seat rotatably connected to the movable seat, a rotating shaft fixedly connected to the output shaft on the other side of the dual-axis motor, a gear fixedly connected to one end of the rotating shaft, and a gear ring fixedly connected to the outer wall of the rotating seat, with the gear meshing with the gear ring.

[0013] Furthermore, the pushing component includes a fourth cylinder installed in the rotating seat, and a push plate is fixedly connected to the movable end of the fourth cylinder; The pressing assembly includes several sliding rods that are slidably connected to the rotating seat. Two U-shaped sliding plates are fixedly connected to one end of each sliding rod. Several springs are fixedly connected to one side of each U-shaped sliding plate, and the other ends of each spring are fixedly connected to the inner wall of the rotating seat. Several electromagnets are fixedly connected to the rotating seat. Two magnets are fixedly connected to one side of each U-shaped sliding plate. An inclined block is slidably connected to one side of each U-shaped sliding plate. An inclined plate is slidably connected to one side of each U-shaped sliding plate. Several push shafts are rotatably connected inside the inclined plate, and the push shafts are in contact with one side of the inclined block.

[0014] Furthermore, the shearing assembly includes a fifth cylinder fixedly connected to one side of the sliding seat, a sixth cylinder fixedly connected to the movable end of the fifth cylinder, and a pneumatic shear fixedly connected to the movable end of the sixth cylinder.

[0015] Furthermore, the pallet feeding assembly includes a third lifting electric slide rail fixedly connected to one side of the frame, a second translation electric slide rail fixedly connected to one side of the third lifting electric slide rail, a third translation electric slide rail fixedly connected to one side of the second translation electric slide rail, and two electric push rods installed opposite each other on one side of the third translation electric slide rail.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation between the drive component, pneumatic gripper, and strapping component, the precise placement of the plastic strapping and the positioning of the goods can be achieved, ensuring that the goods are tightly attached to the plastic strapping. This avoids the impact of stacking position deviation on the packing accuracy, provides a stable load-bearing and positioning foundation for subsequent strapping, and improves the stability of the initial packing operation. Through the cooperation between the take-up assembly, drive assembly, and clamping assembly, the automatic winding and tightening of the plastic steel belt and the positioning and clamping of the double-layer belt can be achieved. The torque motor precisely controls the tightening force to prevent the plastic steel belt from breaking or the binding from loosening, effectively improving the binding tightness and the safety of cargo stacking. By promoting the cooperation between the push component and the pressing component, the double-layer stacked plastic steel strip can be compacted, eliminating the gap between the strips and reducing the thickness. This physically avoids shear deviation and solves the defects of existing technology where unilateral shearing is prone to deviation and cannot cut through, ensuring accurate and stable shearing position. By coordinating the translation and rotation components, the double-layer plastic steel belt can be adjusted to the optimal oblique shear angle, reducing the shearing load and blade wear of vertical straight shearing, significantly improving the one-time cutting rate of the double-layer plastic steel belt, and extending the service life of the shearing components. By setting up the pallet feeding component, the pallet can be automatically grabbed and transported to the packaging station, realizing automatic pallet replenishment and station pre-setting after packaging. This breaks the separate operation mode of packaging and pallet placement, eliminates the time-consuming process connection, and improves the efficiency of continuous operation of the production line. By coordinating multiple components such as the strapping assembly, shearing assembly, and driving assembly, continuous plastic strapping packaging operations can be achieved, simplifying the cumbersome packaging process, reducing the degree of manual intervention, solving the problems of scattered processes and poor binding consistency in existing technologies, and improving the standardization level of packaging operations.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the current technical issues where plastic strapping is mostly done manually, increasing labor costs and worker fatigue, and also leading to strapping misalignment, pallet misplacement, and affecting stacking stability, such as… Figure 1 , Figure 2 and Figures 4-15 As shown, the following preferred technical solutions are provided: like Figure 1 and Figure 2As shown, a semi-automatic plastic strapping machine includes a frame 1, which serves as the overall support carrier for the equipment, providing the installation foundation and movement space for each component. A controller is installed on the side wall of the frame 1, which can control various electrical components. The controller is existing technology and is not shown in the figure. A first crossbeam 11 is installed inside the frame 1, and a drive assembly 2 is installed inside the frame 1. A second crossbeam 3 is installed on one side of the drive assembly 2. The drive assembly 2 can output power in the X and Z axes to drive the second crossbeam 3 and its supporting components to complete the displacement action. Two strapping assemblies 4 are arranged opposite each other on the top of the first crossbeam 11. Each strapping assembly 4 contains a plastic strapping body 48. One end of the plastic strapping body 48 is secured by an external winding mechanism. Two pneumatic grippers 5 are arranged opposite each other on one side of the second crossbeam 3. Figure 5 As shown, two clamping components 6 are arranged opposite each other on the other side of the second crossbeam 3. The pneumatic gripper 5 can clamp and fix the end of the plastic steel strip body 48 and release it. The two clamping components 6 can clamp and position the double-layer stacked plastic steel strip body 48. Figure 7 As shown, each of the two unloading assemblies 4 is equipped with a take-up assembly 7. The take-up assembly 7 can rotate and wind up to tightly wrap the plastic steel strapping body 48 to secure the goods. Figure 8 As shown, each of the two tape-releasing components 4 has a translation component 8 on one side, a rotation component 9 at one end of the translation component 8, a push component 10 inside the rotation component 9, and two pressing components 20 opposite each other inside the rotation component 9. The push component 10 is attached to one side of the two pressing components 20. Each of the two tape-releasing components 4 has a shearing component 30 on one side. The shearing component 30 can perform a stable and precise cutting operation on the double-layer stacked plastic steel tape body 48.

[0021] In use, the controller moves the take-up components 7 in the two tape-laying components 4 to the un-take-up position. The plastic steel strap body 48 is then manually placed in the two tape-laying components 4. The controller then drives the drive component 2 to move the second crossbeam 3 and the two pneumatic grippers 5 to the appropriate position. The two pneumatic grippers 5 clamp and fix one end of the plastic steel strap body 48. The controller then drives the drive component 2 to lower the second crossbeam 3, the two pneumatic grippers 5, and the plastic steel strap body 48 along the Z-axis to the appropriate height, and then move them along the X-axis to the appropriate position. The goods are then stacked on top of the plastic steel strap using external palletizing equipment. This provides a stable bearing and positioning foundation for subsequent plastic steel strap bundling, ensuring that the goods are tightly attached to the plastic steel strap body 48 and preventing stacking position deviations from affecting the accuracy of subsequent packaging operations.

[0022] After palletizing, the controller causes the drive assembly 2 to lift the second crossbeam 3, two pneumatic grippers 5, and the plastic steel strap body 48 along the Z-axis to a suitable height, and then move them back to a suitable position along the X-axis. At this time, the plastic steel strap body 48 is in a double-layer stacked state. Then, the controller causes the take-up assembly 7 to move to the take-up position. At this time, the upper plastic steel strap body 48 is inside the take-up assembly 7. Then, the controller causes the pneumatic grippers 5 to release their clamping and fixing of one end of the plastic steel strap body 48. Then, the controller causes the take-up assembly 7 to rotate, causing the plastic steel strap body 48 to wrap tightly around the take-up assembly 7. The take-up assembly 7 stops rotating when the torque reaches a predetermined value, thereby causing the plastic steel strap body 48 to wrap tightly around the take-up assembly 7. The steel strap body 48 is used to secure the goods. Then, the clamping component 6 presses the double-layered stacked plastic steel strap body 48. Next, the controller causes the shearing component 30 to cut the plastic steel strap body 48. Then, manually, the two ends of the plastic steel strap body 48 are fixed by external C-shaped metal buckles at the overlapping positions. Finally, the controller causes the drive component 2 to drive the second crossbeam 3, two pneumatic grippers 5 and the clamping component 6 to rise along the Z-axis. The plastic steel strap body 48 rebounds and tightly binds the goods, thus completing the secure binding and shaping of the goods. Compared with the existing technology where the plastic steel strapping process is independent and the binding is easy to loosen, this method can improve the binding tightness and the safety of goods stacking.

[0023] Before the shearing component 30 cuts the double-layered stacked plastic steel strip body 48, the controller rotates one end of the translation component 8, causing the rotating component 9, the pushing component 10, and the pressing component 20 to move until the double-layered stacked plastic steel strip body 48 is within the rotating component 9. Then, the controller moves the two pressing components 20 closer together until they are in contact. Afterwards, the controller moves the pushing component 10 to push the pressing structures within the two pressing components 20 closer together, pressing the double-layered stacked plastic steel strip body 48 together. This eliminates the gap between the double-layered stacked plastic steel strip body 48 and simultaneously thins and compacts the thickness, physically preventing shear deviation. Compared to the shortcomings of existing technologies where unilateral shearing is prone to deviation and cannot cut completely, this method ensures the shearing position... The device is positioned precisely and stably. Then, through the controller, the clamping structures in the two pressing components 20 are moved away from each other and reset. The pushing component 10 pushes the clamping structures in the two pressing components 20 closer together, clamping and fixing the double-layer stacked plastic steel strip body 48. Then, through the controller, the other end of the translation component 8 is rotated, so that the pushing component 10 and the two pressing components 20 rotate synchronously with the clamped and fixed double-layer stacked plastic steel strip body 48 to a suitable angle, thereby adjusting the plastic steel strip body 48 to the optimal oblique shearing angle. Compared with the existing technology, which has problems such as high resistance and easy wear of the blade in vertical straight shearing, it can reduce the shearing load and improve the one-time cutting rate of double-layer strip. Then, the shearing component 30 cuts the double-layer stacked plastic steel strip body 48.

[0024] A pallet feeding assembly 40 is provided on one side of the frame 1. The pallet feeding assembly 40 can grab and transport pallets, automatically sending pallets from the external pallet rack to the packaging station. After the packaging operation is completed by the plastic steel strap body 48, the pallets and goods are transported out by external transfer equipment. Then, through the controller, the pallet feeding assembly 40 transports the pallets from the external pallet rack to the packaging station, thereby realizing the automatic replenishment of pallets and the pre-setting of the station after packaging. Compared with the existing technology of packaging and pallet placement being carried out in separate steps, this can eliminate the time-consuming process connection and improve the efficiency of continuous production line operation.

[0025] like Figure 2 As shown, the drive assembly 2 includes a first lifting electric slide rail 21 fixedly connected to the frame 1, a first translation electric slide rail 22 fixedly connected to one side of the first lifting electric slide rail 21, a second lifting electric slide rail 23 fixedly connected to one side of the first translation electric slide rail 22, and a second crossbeam 3 fixedly connected to the second lifting electric slide rail 23.

[0026] like Figures 7-13 As shown, the tape feeding assembly 4 includes a sliding seat 41 fixedly connected to the top of the first crossbeam 11. A first cylinder 42 is installed on the top of the sliding seat 41. A limit plate 43 is fixedly connected to the top of the first cylinder 42. A limit groove 44 is opened at the bottom of the limit plate 43. A second cylinder 45 is installed on the top of the limit plate 43. A sliding frame 46 is fixedly connected to the output end of both the first cylinder 42 and the second cylinder 45. The sliding frame 46 is slidably connected to the sliding seat 41. A limit seat 47 is fixedly connected to the top of the sliding seat 41. A guide groove is opened on the top of the limit seat 47, which can straight guide and laterally limit the plastic steel tape body 48 to ensure the stability of the conveying path of the plastic steel tape body 48. At the same time, it provides a pressing and positioning reference for the pressing assembly 6 to avoid the plastic steel tape from shifting and wrinkling during the conveying and pressing process. A limit roller 49 is rotatably connected inside the limit seat 47, and the plastic steel tape body 48 is in contact with the limit roller 49.

[0027] like Figure 6 As shown, the clamping assembly 6 includes a third cylinder 61 fixedly connected to one side of the second crossbeam 3. The movable end of the third cylinder 61 is fixedly connected to a pressure block 62, and the shape of the pressure block 62 matches the guide groove.

[0028] like Figures 9-11As shown, the take-up assembly 7 includes a motor 71 installed on one side of the sliding frame 46. The motor 71 is a geared motor 71 with torque detection function, which can output a stable take-up torque and monitor the tightening torque in real time. When the take-up torque reaches the preset value, it automatically stops rotating to ensure that the tightening force of the plastic steel belt is uniform and moderate, and to avoid breakage or loosening of the binding. The output end of the motor 71 is fixedly connected to a first rotating shaft 72, and a second rotating shaft 73 is rotatably connected inside the sliding frame 46. Both the outer walls of the first rotating shaft 72 and the second rotating shaft 73 are fixedly connected to sprockets 74. The two sprockets 74 are connected by a chain 75. One end of the second rotating shaft 73 has a take-up groove 76. In use, the moving ends of the first cylinder 42 and the second cylinder 45 drive the two sliding frames 46 to move away from each other at the top of the sliding seat 41. At the same time, the motor 71 drives the first rotating shaft 72 to rotate, and through the transmission of the sprockets 74 and the chain 75, the second rotating shaft 73 rotates synchronously until the take-up groove 76 at one end of the second rotating shaft 73 is in a horizontal position. This is the initial position.

[0029] like Figure 13 As shown, the translation component 8 includes a threaded rod 81 threadedly connected to the limiting seat 47. One end of the threaded rod 81 is rotatably connected to a movable seat 82. Two guide rods 84 are fixedly connected in parallel to one side of the movable seat 82. Both guide rods 84 are slidably connected to the limiting seat 47. A dual-axis motor 83 is installed inside the movable seat 82. The dual-axis motor 83 is a dual independent output shaft drive motor, which can control the rotation of the two output shafts independently, realizing synchronous drive of translation and rotation by a single power source. The threaded rod 81 is fixedly connected to one output shaft of the dual-axis motor 83.

[0030] like Figures 13-15 As shown, the rotating assembly 9 includes a rotating seat 91 rotatably connected to the movable seat 82, a rotating shaft 92 fixedly connected to the output shaft of the dual-axis motor 83 on the other side, a gear 94 fixedly connected to one end of the rotating shaft 92, and a gear ring 93 fixedly connected to the outer wall of the rotating seat 91, with the gear 94 meshing with the gear ring 93.

[0031] like Figure 14 and Figure 15 As shown, the pushing assembly 10 includes a fourth cylinder 101 installed in the rotating seat 91, and a push plate 102 is fixedly connected to the movable end of the fourth cylinder 101. The pressing assembly 20 includes several sliding rods 202 that are relatively slidably connected within the rotating seat 91. One end of each sliding rod 202 is fixedly connected to two U-shaped sliding plates 201. Several springs 203 are fixedly connected to one side of each of the two U-shaped sliding plates 201, and the other ends of each spring 203 are fixedly connected to the inner wall of the rotating seat 91. Several electromagnets 204 are relatively fixedly connected within the rotating seat 91. Two magnet blocks 205 are fixedly connected to one side of each of the two U-shaped sliding plates 201. Inclined blocks 206 are relatively slidably connected to one side of each of the two U-shaped sliding plates 201. Inclined plates 207 are relatively slidably connected to one side of each of the two U-shaped sliding plates 201. Several push shafts 208 are rotatably connected within the inclined plates 207, and the push shafts 208 are in contact with one side of the inclined blocks 206.

[0032] like Figures 9-11 As shown, the shearing assembly 30 includes a fifth cylinder 301 fixedly connected to one side of the sliding seat 41, a sixth cylinder 302 fixedly connected to the movable end of the fifth cylinder 301, and a pneumatic shear 303 fixedly connected to the movable end of the sixth cylinder 302.

[0033] In use, the controller extends the first cylinder 42 and the second cylinder 45, while the take-up groove 76 is initially in a horizontal position. Then, manually, one end of the plastic steel belt body 48 is sequentially passed through the limiting groove 44 and the guide groove, thus installing the plastic steel belt body 48. Subsequently, the controller, in conjunction with the first lifting electric slide rail 21, the first translation electric slide rail 22, and the second lifting electric slide rail 23, moves the second crossbeam 3 and the two pneumatic grippers 5 to the appropriate position. The controller then clamps and fixes one end of the plastic steel belt body 48. The controller enables the first lifting electric slide rail 21, in conjunction with the second lifting electric slide rail 23, to lower the second crossbeam 3, the two pneumatic grippers 5, and the plastic steel strap body 48 along the Z-axis to a suitable height. Then, the first translation electric slide rail 22 moves the body to a suitable position along the X-axis, enabling the installation of the plastic steel strap body 48. Subsequently, external palletizing equipment is used to palletize the goods, placing them on top of the plastic steel strap. This provides a stable bearing and positioning foundation for subsequent plastic steel strap bundling, ensuring that the goods are tightly fitted to the plastic steel strap body 48 and preventing palletizing position deviations from affecting the accuracy of subsequent packaging operations.

[0034] After palletizing is completed, the controller causes the first lifting electric slide rail 21, in conjunction with the second lifting electric slide rail 23, to lift the second crossbeam 3, the two pneumatic grippers 5, and the plastic steel strap body 48 along the Z-axis to a suitable height. Then, the first translation electric slide rail 22 moves them back to a suitable position along the X-axis. At this point, the plastic steel strap body 48 is in a double-layer stacked state, thus completing the wrapping operation of the palletized goods. Afterward, the controller causes the first cylinder 42 and the second cylinder 45 to shorten and reset, driving the two sliding frames 46 to slide on the sliding seat 41. The upper plastic steel belt body 48 slides relative to the lower shaft and synchronously drives the second rotating shaft 73 to move, so that the upper plastic steel belt body 48 is in the take-up groove 76 opened on one side of the second rotating shaft 73. Then, through the controller, the pneumatic gripper 5 releases the clamping and fixing of one end of the plastic steel belt body 48. Then, through the controller, the motor 71 drives the first rotating shaft 72 to rotate, and through the transmission of the sprocket 74 and the chain 75, the second rotating shaft 73 rotates synchronously, so that the plastic steel belt body 48 is wrapped and tightened around the second rotating shaft 73, thereby binding the plastic steel belt body 48 to the goods.

[0035] Simultaneously, during the winding and tightening process of the plastic steel strip body 48, one end of the plastic steel strip body 48 is fixed by an external winding mechanism to prevent slippage and loosening of the plastic steel strip end during tightening. Then, the movable end of the third cylinder 61 extends, driving the pressure block 62 to descend and press the double-layered stacked plastic steel strip body 48. Afterwards, the controller causes the fifth cylinder 301 to work in conjunction with the sixth cylinder 302 to drive the pneumatic shears 303 to move to the appropriate position, and the pneumatic shears 303 cuts the plastic steel strip body 48. Finally, the plastic steel strip body 48 is cut manually or by external means. The C-type metal buckle set overlaps at both ends of the plastic steel strap body 48 to fix the two ends of the plastic steel strap. Finally, through the controller, the first lifting electric slide rail 21, together with the first translation electric slide rail 22 and the second lifting electric slide rail 23, drives the second crossbeam 3, two pneumatic grippers 5 and pressure block 62 to rise along the Z-axis. At this time, the plastic steel strap body 48 rebounds and tightly binds the goods, thereby completing the firm binding and shaping of the goods. Compared with the existing technology, which has the problems of independent plastic steel strap packaging process and easy loosening of binding, it can improve the binding tightness and the safety of goods stacking.

[0036] Through the cooperation between the above-mentioned winding component 7, drive component 2, pneumatic gripper 5, and pressing component 6, the continuous operation of automatic winding and tightening of plastic steel strapping, double-layer positioning and pressing, and secure bundling of goods can be realized. Compared with the existing technology, which has problems such as scattered plastic steel strapping processes, cumbersome manual operation, and poor bundling consistency, it can effectively simplify the packaging process, reduce the degree of manual intervention, and improve the stability and standardization of packaging operations.

[0037] Before the pneumatic shears 303 cuts the double-layered stacked plastic steel strip body 48, the controller rotates one end of the dual-axis motor 83, driving the threaded rod 81 to rotate synchronously. The threaded rod 81 is connected to the limit seat 47, causing the moving seat 82 to move under the guidance of the two guide rods 84. This causes the rotating seat 91, the fourth cylinder 101, the push plate 102, and the U-shaped sliding plate 201 to move synchronously until the double-layered stacked plastic steel strip body 48 is inside the rotating seat 91. Then, the controller energizes several electromagnets 204, repelling the corresponding magnet blocks 205, causing the two U-shaped sliding plates 201 to approach each other under the limit of the sliding rod 202. The inclined blocks 206 are pressed together and the spring 203 is stretched synchronously. Then, through the controller, the fourth cylinder 101 extends to push the push plate 102 to move, and simultaneously pushes the inclined plate 207 to slide laterally in the U-shaped slide plate 201. During the movement of the two inclined plates 207, they will simultaneously push the two inclined blocks 206 to slide vertically relative to each other in the U-shaped slide plate 201, move closer to each other, and gradually press the double-layer stacked plastic steel strip body 48, so that the gap between the double-layer stacked plastic steel strip body 48 is eliminated, and the thickness is reduced and compacted. This avoids shear deviation from a physical perspective. Compared with the defects of existing technology where unilateral shearing is prone to deviation and cannot be cut, it can ensure accurate and stable shearing position.

[0038] Subsequently, the controller causes the fourth cylinder 101 to reset the push plate 102. Then, several electromagnets 204 are de-energized, and the spring 203 resets the U-shaped slide plate 201 and the inclined block 206. Then, the fourth cylinder 101 extends again to push the push plate 102 to move, so that the two sets of inclined blocks 206 clamp and fix the double-layer stacked plastic steel strip body 48. Then, the controller causes the other end of the dual-axis motor 83 to drive the rotating shaft 92 and gear 94 to rotate. Through the meshing of gear 94 and gear ring 93, the rotating seat 91 rotates in the moving seat 82, thereby synchronously driving the clamped and fixed double-layer stacked plastic steel strip body 48 to rotate to a suitable angle, thereby adjusting the plastic steel strip body 48 to the optimal oblique cutting angle. Compared with the existing technology, which has problems such as high resistance and easy wear of blades when vertically cutting, this can reduce the cutting load and improve the one-time cutting rate of double-layer strips. Then, the pneumatic shears 303 cut the double-layer stacked plastic steel strip body 48.

[0039] To address the technical problem of current semi-automatic plastic strapping machines not easily handling automatic pallet feeding, such as... Figure 1 and Figure 3 As shown, the following preferred technical solutions are provided: like Figure 3As shown, the pallet feeding assembly 40 includes a third lifting electric slide rail 401 fixedly connected to one side of the frame 1. A second translation electric slide rail 402 is fixedly connected to one side of the third lifting electric slide rail 401. A third translation electric slide rail 403 is fixedly connected to one side of the second translation electric slide rail 402. Two electric push rods 404 are installed opposite each other on one side of the third translation electric slide rail 403. L-shaped clamps 405 are fixedly connected to the movable ends of the two electric push rods 404. The L-shaped clamps 405 are slidably connected to the third translation electric slide rail 403. The two L-shaped clamps 405 clamp the pallet body 406.

[0040] After the packaging operation is completed by the plastic steel strap body 48, the pallet and goods are transported out by external transfer equipment. Then, through the controller, the two electric push rods 404 drive the L-shaped clamps 405 to clamp the pallet on the external pallet rack, and transport it to the packaging station through the third lifting electric slide rail 401, the second translation electric slide rail 402 and the third translation electric slide rail 403. This realizes the automatic replenishment of pallets and the pre-positioning of workstations after packaging. Compared with the existing technology of packaging and pallet placement being carried out in separate steps, this can eliminate the time-consuming process connection and improve the efficiency of continuous production line operation.
