Description

Technical Field

[0001] The present invention relates to the technical field of intelligent packaging, and more specifically, to a packaging machine with high working efficiency for intelligent packaging projects. Background Art

[0002] Intelligent packaging engineering aims to protect products, facilitate circulation and promote sales. It integrates multiple disciplines such as materials science, mechanical design, and information technology. The packaging machine is the key equipment for realizing automatic packaging of products in the packaging engineering system. However, the existing packaging machines have the following shortcomings when packaging plastic particles: plastic particles accumulate inside the feed hopper and easily generate static electricity, which causes the plastic particles to clump together and flow poorly, forming an arch bridge effect and causing blockage inside the feed hopper, reducing the smoothness of packaging and thus reducing the efficiency of packaging. In addition, when the bag mouth is sealed by hot pressing, the bag mouth is transferred to the hot pressing plate by transmission. At this time, the bag mouth is not easy to stick tightly and extend from the gap between the two hot pressing plates, causing the bag mouth to be stuck on the hot pressing plate and wrinkles to form, reducing the fit of the bag mouth after sealing, resulting in loose packaging. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a packaging machine with high working efficiency for intelligent packaging engineering, whose structure includes a support plate frame, a discharge hopper is provided on the front surface of the support plate frame, and the upper end of the discharge hopper is fixed to the front surface of the support plate frame through an external support frame, an electric control box is provided at the left end of the support plate frame, and the electric control box is controlled and connected with a discharge valve provided at the bottom of the discharge hopper, a controller is fixedly installed on the outer side of the discharge hopper, the electric control box controls the operation of the controller, a fan is installed inside the discharge hopper, and the operation of the fan is controlled by the controller, an air inlet pipe is connected to the center of the left side of the fan and is in continuous connection with the outside of the discharge hopper, a guide cover is also provided on the upper end of the fan, a lower guide plate is provided on the upper end of the interior of the discharge hopper, and the upper end of the lower guide plate is hinged to the interior of the discharge hopper through a torsion shaft; A lower connecting pipe is fixedly installed at the bottom of the fan, and an electrostatic elimination rod is fixedly installed inside the lower connecting pipe. The electrostatic elimination rod is controlled by a controller. A jet port is embedded in the outer surface of the lower connecting pipe. The upper end of the guide cover is an arc structure, and both sides are lower guide plate structures inclined outward, which can guide the plastic particles to prevent the plastic particles from staying around the fan, and two lower guide plates and torsion shafts are provided, which are symmetrically installed above the guide cover. When the plastic particles enter the discharge hopper, the plastic particles exert elastic force on the lower guide plates on both sides, and the torsion shaft exerts a rebound force, so that the lower guide plates swing to guide the plastic particles downward.

[0004] As a further improvement of the present invention, a filling hopper is provided on the top of the discharge hopper, and plastic particles are added to the inside of the discharge hopper through the filling hopper, and a cylinder is fixedly installed on the front and rear surfaces of the discharge hopper, and the output end at the bottom of the cylinder is connected to a linkage arm, and the middle part of the linkage arm is connected to the axis of a positioning hinged plate fixed to the outer surface of the discharge hopper, and the lower end of the linkage arm is also connected to the axis with a clamping piece, and the clamping piece is located outside the discharge pipe set at the bottom of the discharge hopper, and the linkage arm is in a shaped structure, and the angled end in the middle is connected to the axis of the positioning hinged plate, so that when the cylinder installed at an inward angle pushes the upper end of the linkage arm to move inward and downward, the lower end of the linkage arm drives the clamping piece to move to the inner and upper position outside the discharge pipe, and the two sides of the bag opening above the packaging bag are clamped and fixed on the two sides of the outside of the discharge pipe by the clamping pieces on both sides.

[0005] As a further improvement of the present invention, a transmission belt is installed at the lower end of the front surface of the support plate frame, and driving wheels are installed at the both ends of the transmission belt. A servo motor is installed at the rear end of the driving wheel on the right side. The start and stop of the servo motor is controlled by the electric control box. When the servo motor rotates, it drives the driving wheel to rotate, and the conveyor belt transmits the packaging bag placed on the upper end. A weighing device is also installed on the upper inner side of the left end of the conveyor belt. The weighing device is electrically connected to the electric control box. The weighing device is located directly below the discharge hopper. When the plastic particles inside the discharge hopper are discharged into the packaging bag, the packaging bag is directly above the weighing device, and the weight inside the packaging bag is weighed by the weighing device.

[0006] As a further improvement of the present invention, a hot pressing main unit is fixedly installed on the right side of the front surface of the support plate frame, a docking plate is connected to the bottom of the hot pressing main unit, a locking rod is locked on the docking plate, an adjusting rod is welded at the lower end of the docking plate, and a clamping plate is fixed on the inner side of the adjusting rod. Four docking plates are provided, and two are in a group. The four docking plates are fixed to the upper ends of the two front and rear adjusting rods in a symmetrical manner.

The ends of the pair of splints are inclined surfaces, and the front and rear ends of the pair of splints form a necking structure from the outside to the inside, and the guide rollers are located in the necking position, and the conduction is assisted by the guide rollers.

[0008] The beneficial effects of the present invention are: 1. In the present invention, the airflow is generated by the upper fan, which drives the large number of positive and negative ions generated by the static elimination rod to be dispersed from the injection port to the plastic particles inside the discharge hopper, neutralizing the static electricity on the surface of the plastic particles, thereby eliminating static electricity and preventing the plastic particles from clumping together and flowing poorly, forming an arch bridge effect and causing blockage inside the discharge hopper; 2. In the present invention, the weight inside the packaging bag is weighed by a weighing device. When the weight set for the packaging is reached, the weight sensor inside the weighing device transmits the weight data to the electric control box. After data processing, the electric control box controls the discharge valve to close. At this time, the discharge of the material inside the discharge hopper stops, ensuring that the weight of the plastic particles loaded inside each packaging bag is consistent. In addition, the weight loaded inside the packaging bag is adjusted according to the packaging weight requirements, thereby improving the intelligent effect of packaging discharge. 3. In the present invention, the distance between the two clamping plates installed between the inner sides of the two adjusting rods can be adjusted by rotating the locking rods on the two docking plates on the same group. The guide roller assists in the transmission, which is beneficial for the bag opening of the packaging bag to enter between the two clamping plates. Finally, the hot pressing plate is energized by the hot pressing host, so that the hot pressing plate performs hot pressing and sealing on the bag opening of the packaging bag, thereby improving the firmness of the bag opening sealing.

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings: Example: As attached Figure 1 To the attached Figure 6 As shown: The present invention provides a packaging machine with high working efficiency for intelligent packaging engineering, whose structure includes a supporting plate frame 1, a discharge hopper 2 is provided on the front surface of the supporting plate frame 1, and the upper end of the discharge hopper 2 is fixed to the front surface of the supporting plate frame 1 through an external support frame 21, an electric control box 3 is provided at the left end of the supporting plate frame 1, and the electric control box 3 is controlled and connected with a discharge valve 27 provided at the bottom of the discharge hopper 2, a controller 201 is fixedly installed on the outer side of the discharge hopper 2, the electric control box 3 controls the operation of the controller 201, a fan 202 is installed inside the discharge hopper 2, and the fan 202 is controlled to operate by the controller 201, an air inlet pipe 2021 is connected to the center of the left side of the fan 202 and is in continuous connection with the outside of the discharge hopper 2, a deflector 2022 is further provided at the upper end of the fan 202, a lower guide plate 203 is provided at the upper end of the interior of the discharge hopper 2, and the upper end of the lower guide plate 203 is hinged to the interior of the discharge hopper 2 through a torsion shaft 2031; A lower connecting pipe 2023 is fixedly installed at the bottom of the fan 202, and an electrostatic elimination rod 231 is fixedly installed inside the lower connecting pipe 2023. The electrostatic elimination rod 231 is controlled and operated by the controller 201. A jet port 232 is embedded on the outer surface of the lower connecting pipe 2023. A filling hopper 22 is provided on the top of the discharge hopper 2. Plastic particles are added to the inside of the discharge hopper 2 through the filling hopper 22. A cylinder 23 is fixedly installed on the front and back surfaces of the discharge hopper 2. A linkage arm 24 is connected to the output end of the bottom of the cylinder 23. The middle part of the linkage arm 24 is axially connected to the positioning hinge plate 25 fixed to the outer surface of the discharge hopper 2. The lower end of the linkage arm 24 is also axially connected to a clamping piece 26. The clamping piece 26 is located outside the discharge pipe 28 provided at the bottom of the discharge hopper 2.

[0017] Among them, a transmission belt 4 is installed at the lower end of the front surface of the support plate frame 1, and a driving wheel 41 is installed at the both ends of the transmission belt 4. A servo motor 42 is installed at the rear end of the driving wheel 41 on the right side. The start and stop of the servo motor 42 is controlled by the electric control box 3. When the servo motor 42 rotates, it drives the driving wheel 41 to rotate, and the conveyor belt 4 transmits the packaging bag D placed on the upper end. A weighing device 43 is also installed on the upper inner side of the left end of the conveyor belt 4, and the weighing device 43 is electrically connected to the electric control box 3.

[0018] Among them, a hot pressing main unit 5 is fixedly installed on the right side of the front surface of the support plate frame 1, and a docking plate 51 is connected to the bottom of the hot pressing main unit 5. A locking rod 52 is locked and installed on the docking plate 51. An adjusting rod 53 is welded to the lower end of the docking plate 51. A clamping plate 54 is fixed on the inner side of the adjusting rod 53. Guide rollers 541 are provided on the left and right ends of the clamping plate 54, and a hot pressing plate 542 is embedded on the inner surface of the clamping plate 54. The hot pressing plate 542 is parallel to the surface of the clamping plate 54 and is electrically connected to the hot pressing main unit 5; A preferred technical solution is that the upper end of the deflector 2022 is an arc structure, and both sides are inclined outwards. The lower deflector structure can guide the plastic particles to prevent the plastic particles from staying around the fan 202, and there are two lower guide plates 203 and torsion shafts 2031, which are symmetrically installed above the deflector 2022. When the plastic particles enter the discharge hopper 2, the plastic particles exert elastic force on the lower guide plates 203 on both sides, and the torsion shaft 2031 exerts a rebound force, so that the lower guide plates 203 swing to the plastic particles. The material particles are guided downward to avoid blockage of the plastic particles during filling. The injection ports 232 are provided with a plurality of them, and are distributed in a ring array from top to bottom on the outer surface of the injection ports 232. The upper fan 202 generates airflow, which drives a large number of positive and negative ions generated by the static elimination rod 231 to be dispersed from the injection ports 232 to the plastic particles inside the discharge hopper 2, neutralizing the static electricity on the surface of the plastic particles, thereby eliminating static electricity and preventing the plastic particles from clumping together and flowing poorly, forming an arch bridge effect and causing blockage inside the discharge hopper 2. A preferred technical solution is that the linkage arm 24 is in an L-shaped structure, and the angled end in the middle is connected to the axis of the positioning hinge plate 25, so that when the cylinder 23 installed at an inclined inward angle pushes the upper end of the linkage arm 24 to move inward and downward, the lower end of the linkage arm 24 drives the clamping piece 26 to move to the inner and upper position outside the discharge pipe 28, and the clamping pieces 26 on both sides clamp the two sides of the bag opening above the packaging bag D on the two sides of the discharge pipe 28 to fix it, ensuring that the plastic particles inside the hopper 2 are discharged from the discharge pipe 28. When the plastic particles are discharged into the packaging bag D, the bag opening of the packaging bag D will not fall off the discharge pipe 28. The discharge pipe 28 is made of rubber and has good elasticity. When the plastic particles are discharged into the packaging bag D, the bag opening of the packaging bag D exerts traction on the discharge pipe 28 when the packaging bag D moves, causing the rubber discharge pipe 28 to elastically deform, ensuring that the packaging bag D can be removed from the discharge pipe 28. The discharge pipe 28 can quickly rebound and reset after elastic deformation, and the discharge work can continue; A preferred technical solution is that the weighing device 43 is located just below the discharge hopper 2. When the plastic particles inside the discharge hopper 2 are discharged into the packaging bag D, the packaging bag D is just above the weighing device 43. The weight inside the packaging bag D is weighed by the weighing device 43. When the weight set for the packaging is reached, the weight sensor inside the weighing device 43 transmits the weight data to the electric control box 3. After data processing, the electric control box 3 controls the discharge valve 27 to close. At this time, the discharge of the material inside the discharge hopper 2 is stopped, ensuring that the weight of the plastic particles loaded inside each packaging bag D is consistent. In addition, the weight loaded inside the packaging bag D is adjusted according to the packaging weight requirements, thereby improving the intelligent effect of packaging discharge. A preferred technical solution is that four docking plates 51 are provided, and two form a group. The four docking plates 51 are fixed to the upper ends of the two front and rear adjustment rods 53 in a front-to-back and left-to-right symmetrical manner. The two docking plates 51 in the same group can adjust the distance between the two clamping plates 54 installed between the inner sides of the two adjustment rods 53 by rotating the locking rod 52, thereby preventing the two clamping plates 54 from loosening due to wear over a long period of use and being unable to compact and seal the bag opening of the packaging bag D; A preferred technical solution is that the ends of the pair of clamps 54 are inclined surfaces, and the ends of the front and rear two pairs of clamps 54 form a necking structure from the outside to the inside, and the guide roller 541 is located in the necking direction. The guide roller 541 assists in conduction, which is beneficial for the bag opening of the packaging bag D to be transmitted between the two pairs of clamps 54. Finally, the hot pressing host 5 is energized for the hot pressing plate 542, so that the hot pressing plate 542 performs hot pressing and sealing on the bag opening of the packaging bag D, thereby improving the firmness of the sealing of the bag opening of the packaging bag D.

[0019] In the present invention, when the packaging machine is in use, the packaging bag D is placed on the conveyor belt 4 and the bottom of the packaging bag D is located above the weighing device 43. The discharge pipe 28 extends into the bag opening above the packaging bag D. The two cylinders 23 are started to operate synchronously, pushing the linkage arm 24 to move in conjunction. The two clamping pieces 26 clamp the bag opening of the packaging bag D to the outside of the discharge pipe 28. Then, the discharge valve 27 at the bottom inner side of the discharge hopper 2 is opened to discharge the plastic particles inside the discharge hopper 2 downwards, and discharged into the packaging bag D through the discharge pipe 28. When the plastic particles are discharged from the discharge hopper 2, the fan 202 and the static elimination rod 231 need to be started to work synchronously. Under the ventilation of the air inlet pipe 2021, the fan 202 draws the external air into the fan 202 and ejects the airflow from the injection port 232 inside the lower pipe 2023. During the ejection process, the airflow carries a large number of positive and negative ions generated by the static elimination rod 231 and disperses them onto the plastic particles inside the discharge hopper 2, neutralizing the static electricity on the surface of the plastic particles, thereby eliminating the static electricity of the plastic particles and preventing the plastic particles from clumping together and flowing poorly, forming an arch bridge effect and causing blockage inside the discharge hopper 2. After the weighing device 43 detects that the plastic particles loaded inside the packaging bag D have reached the set weight, the electrical control box 3 controls the unloading valve 27 to close and stop unloading. At this time, the servo motor 42 starts to drive the driving wheel 41 to drive the transmission belt 4 to run. The transmission belt 4 transmits the packaging bag D loaded with plastic particles to the direction of the hot pressing main unit 5. A necking structure is formed from the outside to the inside through the ends of the two front and rear clamping plates 54, and the guide roller 541 assists in the conduction, so that the bag opening of the packaging bag D is transmitted between the two clamping plates 54. Finally, the hot pressing main unit 5 energizes the hot pressing plate 542, so that the hot pressing plate 542 performs hot pressing and sealing on the bag opening of the packaging bag D.
