TECHNICAL FIELD

[0002] The packaging conveyor is a key device for realizing continuous, reliable and fast conveying of materials (bottles, cans, bags, boxes, etc.) from one process to the next process on a packaging production line; it has functions of positioning, distribution, stacking, metering, etc., and is a core device for realizing full-automatic packaging, improving production capacity and reducing labor intensity.

[0003] In related technologies, in order to prevent the conveying belt from being directly contacted with the limiting plate to cause abrasion, for example, the prior art with the publication number CN221875299U provides a belt packaging conveyor, which adopts a deviation rectifying mechanism to realize automatic deviation rectification of the conveying belt through the cooperation of the ball and the sliding groove, avoids the direct contact of the conveying belt with the side frame, reduces the abrasion of the conveying belt, and improves the service life and conveying efficiency of the conveying belt.

[0004] Although the prior art in the above can realize the effect of limiting the conveying belt to prevent abrasion by setting the sliding groove on the conveying belt and cooperating with the ball, the ball is prone to jamming due to lack of lubrication during use, which causes the rolling friction between the ball and the conveying belt to change into sliding friction, thereby causing the conveying belt to emit noise. After the ball is lubricated, the lubricant on the surface of the ball will adhere to the sliding groove, causing pollution to the conveying belt and waste of lubricant, and the sliding groove is more prone to accumulate dust and is difficult to clean, so there is a defect that the conveying belt will jam and produce noise during operation.

DETAILED DESCRIPTION

[0021] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0022] The present application will be further described below with reference to the embodiments.

[0023] Please refer to Figures 1-13 , the present application provides a technical solution: a packaging conveyor, see Figure 1 and Figure 4 , comprising a packaging conveying belt 1, a support plate 2, a bag supporting assembly 3 and a feeding assembly 4, the inner side of the packaging conveying belt 1 is provided with a driving roller 11 and a tensioning roller 12 for driving the packaging conveying belt 1 to run; the support plate 2 is uniformly provided with a plurality of support plates 2 along the outer surface of the packaging conveying belt 1, and the top of each two adjacent support plates 2 is respectively fixedly provided with a first half box body 21 and a second half box body 22, and an isolation space for containing articles is formed between the first half box body 21 and the second half box body 22, for receiving the first packaging bag conveyed by the feeding conveying belt 100, and the discharging end of the feeding conveying belt 100 is provided with a material guide groove 101 corresponding to the isolation space; the bag supporting assembly 3 is arranged on the outer side of the two adjacent support plates 2 corresponding to the first half box body 21 and the second half box body 22; as shown in Figure 2 and Figure 3 , the feeding assembly 4 is arranged below the packaging conveying belt 1 for receiving the packaging bag released by the bag supporting assembly 3; wherein, as shown in Figure 5 and Figure 6 , the inner side of the packaging conveying belt 1 is provided with a limiting groove 13, and the outer sides of the driving roller 11 and the tensioning roller 12 are matched with the limiting groove 13, and the outer side of the packaging conveying belt 1 is uniformly provided with a threaded sleeve 19, the threaded sleeve 19 is pre-sealed in the inner side of the packaging conveying belt 1, and the threaded sleeve 19 is located on both sides of the limiting groove 13, for cooperating with the screw to install the support plate 2; the bag supporting assembly 3 automatically triggers the bag supporting action when it is rotated downward from the top of the packaging conveying belt 1, and automatically triggers the releasing action when it is rotated to the bottom of the packaging conveying belt 1.

[0024] When the driving roller 11 and the tension roller 12 drive the packaging conveying belt 1 to run, the limiting groove 13 on the inner side of the packaging conveying belt 1 cooperates with the outer side of the driving roller 11 and the tension roller 12, which can prevent the packaging conveying belt 1 from being axially offset outside the driving roller 11 and the tension roller 12, thereby ensuring the stability of the packaging conveying belt 1, and increasing the contact area between the packaging conveying belt 1 and the outer circumferential side of the driving roller 11 and the tension roller 12, thereby effectively dispersing the pressure between the packaging conveying belt 1 and the driving roller 11 and the tension roller 12, reducing wear caused by long-term operation, and prolonging the service life of the equipment.

[0025] Meanwhile, the support plates 2 are evenly arranged along the outer surface of the packaging conveying belt 1, and the top of the adjacent two support plates 2 forms an isolation space through the first half box body 21 and the second half box body 22. Such a design not only facilitates the reception of the first packaging bag conveyed by the feeding conveying belt 100, but also ensures the stability and orderliness of the packaging bag during the conveying process, avoiding mutual extrusion and confusion between the packaging bags.

[0026] By arranging the bag supporting assembly 3 corresponding to the first half box body 21 and the second half box body 22 outside the adjacent two support plates 2, the bag supporting assembly 3 can accurately contact the packaging bag and automatically trigger the bag supporting action when it is rotated from the top of the packaging conveying belt 1 downward, so as to open the packaging bag for subsequent filling and sealing. When the bag supporting assembly 3 is rotated to the bottom of the packaging conveying belt 1, it can also automatically trigger the release action to stably place the packaging bag on the discharging assembly 4, thereby realizing the automatic conveying and releasing of the packaging bag. In addition, the discharging assembly 4 is arranged below the packaging conveying belt 1 to receive the packaging bag released by the bag supporting assembly 3, which makes the entire conveying process more smooth and efficient. At the same time, the design of the discharging assembly 4 also takes into account the subsequent sealing and packaging requirements, providing convenience for subsequent automated production.

[0027] Referring to Figure 7 , the bag supporting assembly 3 includes a first vertical plate 31 and a second vertical plate 32 fixedly arranged outside the adjacent two support plates 2, respectively. The outer side of the upper end of the first vertical plate 31 is fixedly provided with a first inclined plate 33, and the first inclined plate 33 is located away from the second vertical plate 32. The top of the second vertical plate 32 is rotatably provided with a rotating plate 34, and the side of the rotating plate 34 away from the first inclined plate 33 is fixedly provided with a second inclined plate 35. When the second inclined plate 35 and the first inclined plate 33 are located at the top of the packaging conveying belt 1, they are arranged in an inverted V shape. When the rotating plate 34 is inclined by rotating downward from the top of the packaging conveying belt 1, it automatically triggers the bag supporting action by relying on its own gravity.

[0028] When the first inclined plate 33 on the first vertical plate 31 and the second inclined plate 35 carried by the rotating plate 34 rotatingly arranged on the second vertical plate 32 present an "inverted V" shape at the top of the packaging conveying belt 1, the first inclined plate 33 and the second inclined plate 35 are ready to receive the packaging bag, so as to facilitate the staff or automatic equipment to perform the bagging work. During the downward rotation of the rotating plate 34 from the top of the packaging conveying belt 1, as the inclination angle of the rotating plate 34 gradually increases, the rotating plate 34 and the second inclined plate 35 can trigger the bag opening action accurately and stably by relying on the gravity, so as to ensure that the packaging bag is smoothly opened. When the bag opening action is completed, as the opening of the first half box body 21 and the second half box body 22 is inclined downward, the filling operation of the packaging bag can be triggered again. When the rotating plate 34 continues to rotate to the bottom of the packaging conveying belt 1, the releasing action can be smoothly completed, and the packaging bag is accurately placed on the discharging assembly 4. The whole process realizes the automatic operation of the packaging bag opening and releasing, and improves the working efficiency and stability of the packaging conveyor. At the same time, the specific position setting of the first inclined plate 33 and the second inclined plate 35 ensures the accuracy and reliability of the bag opening action, and avoids the situation that the packaging bag slips or is not opened in place during the operation.

[0029] As shown in Figure 7 and Figure 8 , the rotating end of the rotating plate 34 is fixedly provided with a rotating block 36, and the outer side of the second vertical plate 32 is fixedly provided with a limiting block 37 corresponding to the rotating block 36. The side of the limiting block 37 close to the rotating block 36 is provided with a limiting inclined surface 38, and the rotating block 36 is arranged outside the limiting inclined surface 38 by magnetic adsorption.

[0030] When the rotating plate 34 rotates to a specific position, the rotating block 36 will be closely attached to the limiting inclined surface 38 by magnetic adsorption. This design not only enhances the stability of the rotating plate 34 during the rotation from the top to the bottom of the packaging conveying belt 1, but also can be easily separated by external force when needed, realizing the flexible rotation of the rotating plate 34 and the stability of the bag opening.

[0031] The both sides of the driving roller 11 and the tensioning roller 12 are rotatingly provided with a guard plate 14, and the bottom of the guard plate 14 is fixedly provided with a discharging channel 6. The discharging channel 6 is located at the end of the bottom of the packaging conveying belt 1 away from the feeding conveying belt 100. When the rotating plate 34 passes through the discharging channel 6, the releasing action is automatically triggered, and the packaging bag is placed on the top of the discharging assembly 4.

[0032] Specifically, referring to Figure 7 and Figure 9The rotating end of the rotating plate 34 is fixedly provided with a fixed pin 39, the fixed pin 39 is rotationally arranged on the inner side of the second vertical plate 32, one end of the fixed pin 39 away from the rotating plate 34 is fixedly provided with a protruding block 310, the protruding block 310 is arranged in an inclined manner in the initial state, and the inclination angle of the protruding block 310 relative to the vertical line is equal to the rotation angle of the rotating plate 34; for reference Figure 11 and Figure 12 The extension plates 61 are fixedly arranged on both sides of the feeding channel 6, the extension plates 61 are located on the outer side of the bag supporting assembly 3, one side of the extension plate 61 close to the bag supporting assembly 3 is fixedly provided with a fixed shaft 62, the outer side of the fixed shaft 62 is rotationally provided with a sleeve 63, the sleeve 63 is arranged on the horizontal movement path of the protruding block 310, and is used for triggering the rotation of the rotating plate 34 to release the packaging bag.

[0033] When the packaging bag moves to the position of the feeding channel 6 along the conveying process, the fixed shaft 62 on the extension plate 61 cooperates with the sleeve 63 to form a precise triggering mechanism. Specifically, since the sleeve 63 is located on the horizontal movement path of the protruding block 310, in the packaging bag contacting process, the protruding block 310 is subjected to the resistance of the sleeve 63, and drives the fixed pin 39 to rotate around the rotation point on the inner side of the second vertical plate 32; the rotation action is directly transmitted to the rotating plate 34, so that the rotating plate 34 drives the rotating block 36 and the limiting block 37 to separate from each other, at this time, the rotating plate 34 naturally droops under the action of its own gravity, and then the bag supporting action is released, the automatic feeding of the packaging bag from the rotating plate 34 to the top of the discharging assembly 4 is completed, the whole triggering process is realized through the linkage of the mechanical structure, without the need of an additional power source, so that the synchronization and reliability of the packaging bag conveying and releasing actions are ensured.

[0034] As shown in Figure 10 and Figure 13 The packaging conveyor disclosed in the embodiment of the application further comprises a sealing assembly 5 for sealing the packaging bag released by the bag supporting assembly 3 on the top of the discharging assembly 4; the discharging assembly 4 comprises a box seat 41 located below the packaging conveying belt 1, the inner side of the box seat 41 is provided with a discharging conveying belt 42, the inner side of the discharging conveying belt 42 is provided with a driven roller 43, the driven roller 43 is rotationally arranged on the inner side of the box seat 41, the outer side of the discharging conveying belt 42 is fixedly provided with a partition plate 44 at equal intervals, and the partition plate 44 is used for limiting the upward cooperation of the packaging bag opening with the sealing assembly 5 for heat sealing; specifically, the two sides of the guard plate 14 are fixedly provided with side plates 15, the side plates 15 are fixedly arranged on the outer side of the box seat 41, the outer side of the guard plate 14 on one side is fixedly provided with a driving motor 17 for driving the driving roller 11 to run, the other end of the driving roller 11 is linked with one of the driven rollers 43 through a transmission box 18, the two adjacent partition plates 44 on the outer side of the discharging conveying belt 42 are arranged one by one with the bag supporting assembly 3, and the outer side of the side plate 15 is fixedly provided with a workbench 16 corresponding to the bagging station on the top of the guard plate 14.

[0035] The box seat 41 is arranged as the main supporting structure of the discharging assembly 4, thereby providing a stable mounting basis for the discharging conveying belt 42 and the driven roller 43. When the driven roller 43 arranged inside the discharging conveying belt 42 rotates, it can cooperate with the equally spaced fixed partitions 44 outside the discharging conveying belt 42 to effectively limit the bag opening, thereby ensuring that the bag opening is upward and facilitating the accurate heat sealing operation of the sealing assembly 5. The side plates 15 fixed on both sides of the guard plate 14 not only enhance the stability of the overall structure, but also drive the driving roller 11 to operate through the driving motor 17 arranged on one side, and then drive the two adjacent partitions 44 outside the discharging conveying belt 42 to correspond to the bag supporting assembly 3 through the transmission box 18 and the driven roller 43. This design enables the packaging bag to be located between the adjacent two partitions 44 each time it passes below the discharging channel 6, so as to ensure that the packaging bag can maintain a stable position and posture during the sealing process.

[0036] The sealing assembly 5 comprises a first heat sealing plate 51 and a second heat sealing plate 52, and V-shaped clamping arms 53 are fixedly arranged at both ends of the first heat sealing plate 51 and the second heat sealing plate 52. The two V-shaped clamping arms 53 located on the same side of the first heat sealing plate 51 and the second heat sealing plate 52 are rotationally connected at the top, and the rotationally connected two V-shaped clamping arms 53 are driven by external force to drive the first heat sealing plate 51 and the second heat sealing plate 52 to perform heat sealing opening and closing actions.

[0037] When the first heat sealing plate 51 and the second heat sealing plate 52 perform the heat sealing opening and closing actions, the first heat sealing plate 51 and the second heat sealing plate 52 can contact and heat the bag opening, thereby realizing heat sealing of the bag opening; the V-shaped clamping arms 53 are provided with limiting structures for controlling the rotation angle thereof, so as to ensure that the first heat sealing plate 51 and the second heat sealing plate 52 can accurately reach the appropriate position during the heat sealing opening and closing actions, thereby ensuring the consistency and stability of the heat sealing effect.

[0038] Specifically, the V-shaped clamping arms 53 are each provided with a sliding groove 55 inside, and the two sliding grooves 55 on the same side are arranged in an "eight" shape when the first heat sealing plate 51 and the second heat sealing plate 52 are close to each other. The sliding grooves 55 are each slidably provided with a sliding block 56 inside along the length direction, the sliding blocks 56 on the same side are each rotationally arranged outside a connecting block 57, the connecting block 57 is driven to move up and down by an electric push rod 58, and the V-shaped clamping arm 53 on the other side is rotationally arranged outside the guard plate 14 through a pin shaft 54, and the electric push rod 58 is fixedly arranged outside the guard plate 14.

[0039] When the connecting block 57 is driven to move up and down by the electric push rod 58, the slider 56 on the same side will slide along the length direction inside the sliding groove 55. Since the two sliding grooves 55 on the same side are arranged in the shape of "8", the sliding will further convert into the rotation of the V-shaped clamping arm 53 around the pin shaft 54, so as to realize the more accurate and flexible opening and closing action of the first heat sealing plate 51 and the second heat sealing plate 52, so as to meet the needs of different specifications of packaging bags in the heat sealing process, and ensure that the heat sealing operation can be carried out efficiently and stably.

[0040] In order to make the first heat sealing plate 51 and the second heat sealing plate 52 away from the top of the packaging bag before heat sealing, so as to prevent the rest heat from damaging the packaging bag when contacting the top of the packaging bag, the end of the pin shaft 54 close to the guard plate 14 is fixedly provided with a counterweight 59, the counterweight 59 is slidingly arranged outside the guard plate 14, and the side of the slider 56 away from the pin shaft 54 is fixedly provided with an elastic element 510, which is fixedly located inside the sliding groove 55.

[0041] When the connecting block 57 is driven to move up and down by the electric push rod 58, the slider 56 on the same side will slide along the length direction inside the sliding groove 55. Since the two sliding grooves 55 on the same side are arranged in the shape of "8", the sliding will further convert into the rotation of the V-shaped clamping arm 53 around the pin shaft 54, so as to realize the more accurate and flexible opening and closing action of the first heat sealing plate 51 and the second heat sealing plate 52, so as to meet the needs of different specifications of packaging bags in the heat sealing process, and ensure that the heat sealing operation can be carried out efficiently and stably.

[0042] Principle and advantages of the packaging conveyor: Firstly, the first packaging bag is conveyed into the isolation space formed by the first half box body 21 and the second half box body 22 by the feeding conveyor belt 100 (the feeding conveyor belt 100 is used in cooperation with a primary packaging machine, such as a belt packaging machine), when a certain number of first packaging bags are received in the isolation space, at this time, the driving roller 11 and the tensioning roller 12 drive the packaging conveyor belt 1 to drive and run, the packaging conveyor belt 1 drives the support plates 2 uniformly arranged thereon to move together, so that the isolation space with packaging bags moves to a suitable position; the bag supporting assembly 3 is arranged outside the adjacent two support plates 2 corresponding to the first half box body 21 and the second half box body 22, when the isolation space reaches the specified position, the bag supporting assembly 3 is rotated downward from the top of the packaging conveyor belt 1, and the bag supporting action is automatically triggered in the rotating process to open the packaging bag; With the continuous transmission of the packaging conveying belt 1, the bag opening assembly 3 automatically triggers the release action when it rotates to the bottom of the packaging conveying belt 1, and the opened packaging bag is smoothly placed on the discharging assembly 4 located below the packaging conveying belt 1. The adjacent two partitions 44 on the outside of the discharging conveying belt 42 correspondingly receive the packaging bags dropped in the isolation space, and the packaging bag opening is effectively limited by the equidistantly fixed partitions 44 on the outside of the discharging conveying belt 42, ensuring that the packaging bag opening is upward; Then the driving roller 11 continues to drive the packaging conveying belt 1 to move a certain distance, at this time the driving roller 11 drives the driven roller 43 to rotate a certain angle through the transmission box 18, so that the discharging conveying belt 42 drives the partitions 44 to advance a certain distance. When the partitions 44 and the internal packaging bags move directly below the sealing assembly 5, the connecting block 57 is driven to move up and down by the electric push rod 58. Since the counterweight block 59 slides outside the guard plate 14, it will first drive the V-shaped clamping arm 53 to move downward as a whole. When the counterweight block 59 slides to the bottom and cannot continue to slide, the connecting block 57 continues to drive the sliding block 56 to slide inside the sliding groove 55. Since the sliding blocks 56 on the same side slide along the length direction inside the "8" shaped sliding groove 55, it is converted into the rotation of the V-shaped clamping arm 53 around the pin shaft 54, so that the first heat sealing plate 51 and the second heat sealing plate 52 perform the heat sealing opening and closing action, and the packaging bag opening is heated and sealed. In this process, the first heat sealing plate 51 and the second heat sealing plate 52 maintain a safe distance from the top of the packaging bag before heat sealing, avoiding damage to the packaging bag due to residual heat. The elastic element 510 enhances the stability of the sliding block 56 sliding. The whole heat sealing process is smooth and efficient, and finally the conveying and sealing of the packaging bag are completed.

[0043] The advantages of the whole conveying and sealing process are that it realizes high automation and collaboration, from the initial conveying of the packaging bag, accurate positioning of the isolation space, automatic triggering of the bag opening and release action, to the effective restriction of the packaging bag opening and the precise execution of the heat sealing opening and closing action. Each link is closely connected, reducing manual intervention and greatly improving production efficiency. At the same time, through the cooperation of the limiting groove 13 inside the packaging conveying belt 1 and the outer sides of the driving roller 11 and the tensioning roller 12, the packaging conveying belt 1 can be prevented from axially deviating from the outer sides of the driving roller 11 and the tensioning roller 12, to ensure the stability of the packaging conveying belt 1 running, and also increase the contact area between the packaging conveying belt 1 and the outer circumferential side of the driving roller 11 and the tensioning roller 12, thereby effectively dispersing the pressure between the packaging conveying belt 1 and the driving roller 11 and the tensioning roller 12, reducing wear due to long-term operation, and prolonging the service life of the equipment.

[0044] It is worth noting that the bag opening assembly 3 in the packaging conveyor of the present application is used: Preparation stage, check whether the components of the bag supporting assembly 3 are installed in place, confirm that the first vertical plate 31 and the second vertical plate 32 are fixed firmly, the first inclined plate 33 and the second inclined plate 35 form an inverted V shape and the angle is appropriate, the rotating plate 34 rotates flexibly, the rotating block 36 is normally magnetically adsorbed with the limiting inclined surface 38, the protruding block 310 has a required inclination angle, and the sleeve 63 is on the horizontal movement path of the protruding block 310.

[0045] Bagging stage, the staff or automatic equipment places the packaging bag on the first inclined plate 33 and the second inclined plate 35 which form an inverted V shape to complete the bagging preparation.

[0046] Bag supporting stage, the rotating plate 34 is rotated downward from the top of the packaging conveying belt 1, the inclination angle is increased, and the bag supporting action is triggered by the self-gravity to open the packaging bag.

[0047] Filling stage, after the bag supporting is completed, the first half box body 21 and the second half box body 22 are inclined downward with the opening, and the packaging bag filling operation is performed.

[0048] Release stage, the rotating plate 34 continues to rotate to the position where the discharge channel 6 is located, the protruding block 310 is driven by the resistance of the sleeve 63 to rotate the fixing pin 39, so that the rotating plate 34 is separated from the limiting block 37 and naturally droops, the bag supporting action is released, and the packaging bag is put into the top of the discharging assembly 4.

[0049] Reset stage, after the rotating plate 34 is rotated to the bottom of the packaging conveying belt 1 to complete the release, the packaging conveying belt 1 continues to drive the bag supporting assembly 3 to move from bottom to top, so that the rotating plate 34 and the second inclined plate 35 in the bag supporting assembly 3 are automatically reset with the first inclined plate 33 by the self-gravity, and return to the inverted V shape state to wait for the next working cycle.
