[0002] Pet food is specially provided for pets and small animals, and is a high-grade animal food between human food and traditional livestock and poultry feed. With the increasing market space for pet food, at the same time, the packaging of pet food has also developed rapidly. After the existing food is processed, it needs to be discharged through a conveyor. As an important machine in the field of special intelligent packaging equipment, the conveyor plays an indispensable role.

[0003] The existing conveyor for special intelligent packaging equipment for pet food has the following deficiencies: 1. The pet food packed in bags or boxes is directly discharged to the ground and stacked after being conveyed by the conveyor to achieve blanking. There is no designed transfer structure, and the packaging boxes or bags are directly dropped onto the ground and are easily broken, resulting in the spilling of pet food.

[0017] 3. The present invention can realize the linkage operation of the transfer mechanism and the limit mechanism by designing two traction components, that is, when conveying small and light pet food packaging bags or packaging boxes, the distance between the two baffles is reduced. At this time, the distance between the receiving platform and the conveyor belt is small, and the height difference between the two is small; when conveying large and heavy pet food packaging bags or packaging boxes, the distance between the two baffles is increased. At this time, the distance between the receiving platform and the conveyor belt is reduced, and the height difference between the two is reduced. That is, the distance between the receiving platform and the conveyor belt can be automatically adjusted according to the volume and weight of the product conveyed on the conveyor belt, so as to prevent the packaging bags or packaging boxes from being damaged and causing the pet food to leak, thereby protecting the products and improving the flexibility of the special intelligent packaging equipment.

[0018] 3. The present invention designs a limiting mechanism, namely a driving component, two first sliding components and two baffles, which can adjust the distance between the two baffles according to the volume of the pet product packaging box or packaging bag, thereby limiting the product and making it difficult for the product to fall from the conveyor belt, thereby improving the stability of the product transportation to the receiving platform.

[0019] 4. The present invention, by designing an adjustment component and cooperating with a telescopic component, can adjust the installation height of one of the rollers close to the cylinder, that is, the conveyor belt can be adjusted from an initial horizontal state to an inclined state, and the pet food that falls out of the packaging bag or packaging box during the conveying process can be transported to the inside of the collection box through the feeding chute. By designing the second embodiment, the conveyor belt adjusted to the inclined state can be knocked by a plurality of knocking rods to make it vibrate, so that the pet food with high viscosity can be shaken off, and then transported to the inside of the collection box through the feeding chute, thereby realizing automatic cleaning and collection of the fallen pet food, facilitating recycling and avoiding waste of resources, and preventing the breeding of bacteria, thereby improving the practicality of the special intelligent packaging equipment, and at the same time, no manual cleaning is required, saving labor costs, and further reducing the use and maintenance costs of the special intelligent packaging equipment.

[0020] 5. The present invention designs a telescopic assembly, namely, a cover, a telescopic spring and a slide column. When the height of one of the rollers close to the cylinder is raised, one of the rollers close to the base is pulled by the roller that rises vertically above and will follow the slide column to rise vertically inside the cover. The slide column compresses the telescopic spring to change it from an initial state to a taut state, thereby realizing adaptive adjustment of one of the rollers close to the base, and then cooperating with the other two rollers to tighten the conveyor belt so that it always meets the standard for conveying pet products, further improving the flexibility of the special intelligent packaging equipment.

[0025] Embodiment 1: The present invention provides a technical solution. Refer to Figures 1 to 10As shown, a smart packaging device for pet food includes a base; It also includes a conveying mechanism, a transfer mechanism and a limiting mechanism; The conveying mechanism is arranged on the top of the base, and the conveying mechanism includes a conveyor belt 10, an adjustment component, a telescopic component and three rollers 11. Two vertical plates are symmetrically arranged on the top of the base, the adjustment component is arranged on the outer wall of one of the vertical plates, the telescopic component is arranged on the top of the base, one of the rollers 11 is rotated by a first rotating shaft 12 and is arranged between the two vertical plates, and the other two rollers 11 are respectively arranged on the adjustment component and the telescopic component, and the conveyor belt 10 is sleeved between the three rollers 11; The limiting mechanism is arranged on the two vertical plates, and the limiting mechanism includes a driving assembly, two first sliding assemblies and two baffles 13. The driving assembly is arranged on the top of the base, each first sliding assembly is arranged on the top of a vertical plate, and each baffle 13 is fixed on a first sliding assembly; The transfer mechanism is arranged at the top of the base, and the transfer mechanism includes a receiving platform 14, two traction components, two second sliding components and two docking components. The receiving platform 14 is slidably arranged on the top of the base, and the two docking components are symmetrically arranged at both ends of the receiving platform 14. Each second sliding component is arranged beside a docking component, and each traction component is arranged between a first sliding component and a second sliding component.

[0026] Reference Figures 1 to 10 As shown, the driving assembly includes a bidirectional electric push rod 15 and two L-shaped slide bars 16. The bidirectional electric push rod 15 is fixedly arranged on the top of the base, and each L-shaped slide bar 16 is slidably arranged on the top of the base. The two output ends of the bidirectional electric push rod 15 are respectively fixedly connected to the bottom of the two L-shaped slide bars 16. This special intelligent packaging equipment is equipped with a controller, and each electrical device on the equipment is electrically connected to the controller. In the initial state, the distance between the two baffles 13 is small, which is convenient for limiting the small and light pet food packaging boxes or packaging bags when the conveyor belt 10 is in operation. At this time, the receiving plate 26 is far away from the conveyor belt 10, and the small and light pet food packaging boxes or packaging bags fall to the top of the receiving plate 26. The receiving plate 26 is forced to rotate counterclockwise, and under the action of a plurality of buffer springs 28, a small and light pet food packaging box or packaging bag is buffered to prevent it from falling directly to the ground and causing the packaging box or packaging bag to break, thereby avoiding the spillage of pet food. When the conveyor belt 10 transports a large and heavy pet food packaging box or packaging bag, the two-way electric push rod 15 is started by the controller, so that its two output ends are extended, that is, the two output ends are separated from each other. Since each L-shaped slide bar 16 is slidably connected to the base, the two output ends of the two-way electric push rod 15 are respectively fixedly connected to the bottom of the two L-shaped slide bars 16, thereby driving the two L-shaped slide bars 16 to separate from each other.

[0027] ReferenceFigures 1 to 10 As shown, each first sliding component includes a first sliding plate 17, two L-shaped plates 18, and two insertion rods 19. The first sliding plate 17 is fixedly arranged on the top of one of the L-shaped sliding rods 16. The two L-shaped plates 18 are both fixedly arranged on one of the vertical plates. Each insertion rod 19 slides on one of the L-shaped plates 18. One end of each insertion rod 19 is fixedly connected to the first sliding plate 17, and the other end is fixedly connected to a baffle 13. A receiving groove 20 for inserting the baffle 13 is provided on the outer wall of each vertical plate. Each insertion rod 19 passes through a receiving groove 20. When the two L-shaped sliding rods 16 move away from each other, since the first sliding plate 17 is fixedly connected to the top of one of the L-shaped sliding rods 16, the two L-shaped plates 18 are both fixedly connected to one of the vertical plates, each insertion rod 19 is slidably connected to the L-shaped plate 18, and one end of each first sliding plate 17 and a baffle 13 are respectively fixedly connected to both ends of an insertion rod 19, thus cooperating with another first sliding component to drive the two baffles 13 to move away from each other, increasing the distance between the two baffles 13. Therefore, it is convenient to limit the large-volume and heavy-weight pet food packaging boxes or packaging bags conveyed on the conveyor belt 10, improving the stability of conveying to the receiving table 14.

[0028] Refer to Figures 1 to 10 As shown, two mounting platforms 21 are fixedly arranged on the top of the base. Each second sliding component includes a second sliding plate 22 and two wedge-shaped top blocks 23. Two sliding grooves are formed on the top of each mounting platform 21. A slider 24 is slidably arranged in each sliding groove. Each wedge-shaped top block 23 is fixedly arranged on the top of a slider 24. The second sliding plate 22 is fixedly arranged between the same side walls of the two wedge-shaped top blocks 23. When the second sliding plate 22 slides on the outer wall of the guide rod 38 towards the end close to the receiving table 14, since the same side walls of the two wedge-shaped top blocks 23 are both fixedly connected to the second sliding plate 22, and each wedge-shaped top block 23 is slidably connected to one of the sliding grooves formed on the top of the mounting platform 21 through the slider 24, the two wedge-shaped top blocks 23 are driven to slide towards the end close to the receiving table 14 on the top of the mounting platform 21.

[0029] Figures 1 to 10 Refer to Figures 1 to 10 ​As shown in the figure, the receiving platform 14 includes a U-shaped plate 25, a receiving plate 26, a limiting plate 27 and a plurality of buffer springs 28. Four limiting rods are fixedly arranged on the top of the base. A lifting block 29 is slidably arranged on the outer wall of each limiting rod. The U-shaped plate 25 is fixedly arranged between the four lifting blocks 29. The receiving plate 26 is rotatably arranged on the top of the U-shaped plate 25 through a rotating rod 51. The limiting plate 27 is fixedly arranged at the bottom of the U-shaped plate 25. A plurality of buffer springs 28 are fixedly arranged between the top of the limiting plate 27 and one end of the bottom of the receiving plate 26. Two limiting blocks 30 are symmetrically arranged on the outer wall of one end of the U-shaped plate 25 away from the limiting plate 27. The bottom end of the receiving plate 26 away from the buffer spring 28 is in contact with the top of the two limiting blocks 30. Columnar sliding rods 31 are fixedly arranged at both ends of the receiving plate 26. Arc-shaped grooves for the columnar sliding rods 31 to slide reciprocally are arranged at both ends of the U-shaped plate 25. When the pet food packaging bag or box is conveyed from the top of the conveyor belt 10 and falls onto the top of the receiving plate 26, since the receiving plate 26 is rotatably connected to the two vertical plates through the rotating rod 51, under the supporting and limiting action of the two limiting blocks 30, the receiving plate 26 will rotate counterclockwise. Under the limiting action of the limiting plate 27, a plurality of buffer springs 28 are compressed, causing them to change from the initial state to the tense state, realizing the unloading and buffering of the packaging box and the packaging bag. At the same time, under the rotation action of the rotating plate, the pet food packaging bag or box is automatically driven to slide from the top of the receiving plate 26 to the ground, realizing the feeding. The two columnar sliding rods 31 and the two arc-shaped grooves play a role in limiting and guiding, ensuring the stable rotation of the receiving plate 26, and cooperating with a plurality of buffer springs 28 to realize stable feeding.

[0030] Refer to Figures 1 to 10As shown, each docking component includes a connecting plate 32, two wedge-shaped docking blocks 33 and two connecting columns 34. The two connecting columns 34 are both fixedly arranged at one end of the U-shaped plate 25. The connecting plate 32 is fixedly arranged between the ends of the two connecting columns 34 far away from the U-shaped plate 25. The two wedge-shaped docking blocks 33 are both fixedly arranged on the connecting plate 32. Each wedge-shaped docking block 33 is in contact with a wedge-shaped top block 23. When the two wedge-shaped top blocks 23 slide towards the end close to the receiving platform 14 on the top of the mounting table 21, since the two connecting columns 34 are both fixedly connected to one end of the U-shaped plate 25, the ends of the two connecting columns 34 far away from the U-shaped plate 25 are both fixedly connected to the connecting plate 32, the two wedge-shaped docking blocks 33 are both fixedly connected to the connecting plate 32, and the hypotenuse of each wedge-shaped docking block 33 is in contact with the hypotenuse of a wedge-shaped top block 23, the U-shaped plate 25 is slidably connected to the top of the base through four lifting blocks 29 and four limiting rods. Then, by sliding the two wedge-shaped top blocks 23 towards the end close to the receiving platform 14 to abut against the two wedge-shaped docking blocks 33, the U-shaped plate 25 is driven to rise vertically on the top of the base, and then the receiving plate 26 thereon is driven to rise vertically towards the conveyor belt 10, that is, the distance between the receiving plate 26 and the conveyor belt 10 is reduced, and the gravitational potential energy caused by the falling of large and heavy pet food packaging boxes or packaging bags is reduced for buffering, preventing the large and heavy pet food packaging boxes or packaging bags from directly contacting the ground and being broken, playing a role in protecting the product, and improving the flexibility of this special intelligent packaging equipment.

[0031] Referring to Figures 1 to 10 As shown, each traction component includes a traction rod 35, a pull rope 36, a limiting wheel 37, a guide rod 38 and a return spring 39. The guide rod 38 is fixedly arranged on the top of the base through a support plate. The return spring 39 is sleeved on the outer wall of the guide rod 38, and the support plate and one of the second sliding plates 22 are respectively fixedly connected to both ends of the return spring 39.

The limiting wheel 37 is rotatably arranged on the outer wall of one of the vertical plates. The outer wall of the pull rope 36 is in contact with the outer edge of the limiting wheel 37. When the two baffles 13 move away from each other, that is, when the first sliding plate 17 drives one of the baffles 13 to slide towards the end close to the L-shaped plate 18, since the first sliding plate 17 is fixedly connected to the second sliding plate 22 through the traction rod 35 and the pull rope 36, and the second sliding plate 22 is slidably connected to the guide rod 38, under the limiting action of the limiting wheel 37, the second sliding plate 22 slides towards the end close to the receiving platform 14 on the outer wall of the guide rod 38, so as to compress the return spring 39 through the second sliding plate 22 and change it from the initial state to the taut state.

[0032] Referring to Figures 1 to 10As shown in the figure, the adjustment assembly includes a cylinder 40 and a push block 41. The cylinder 40 is fixedly arranged on the outer wall of one of the vertical plates, and the push block 41 is fixedly arranged on the output end of the cylinder 40. Guide grooves are opened at one end of the two vertical plates close to the cylinder 40. A slide bar 42 is slidably arranged inside each guide groove. The push block 41 is fixedly connected to one of the slide bars 42. A bearing 43 is fixedly arranged on the outer wall of each slide bar 42. A second rotating shaft 44 is fixedly arranged between the inner rings of the two bearings 43. One of the rollers 11 close to the cylinder 40 is fixedly connected to the second rotating shaft 44. A stepping motor 45 is inserted into the outer wall of one of the vertical plates, and its output end is fixedly connected to the end of the first rotating shaft 12. This equipment belongs to an important machine in the field of special intelligent packaging equipment. The conveyor belt 10 plays a key role in the packaging production line. Specifically, when the pet food is packaged, it is necessary to discharge the packaged finished products through the conveyor belt 10. When discharging, first, the controller starts the stepping motor 45. Since its output end is fixedly connected to the end of the first rotating shaft 12, one of the rollers 11 close to the receiving table 14 is rotatably connected to the two vertical plates through the first rotating shaft 12. One of the rollers 11 close to the base is rotatably connected to the sliding column 48 through the third rotating shaft 49. The other roller 11 is rotatably connected to the two slide bars 42 through the second rotating shaft 44 and the two bearings 43. The three rollers 11 are sleeved by the conveyor belt 10, so that the conveyor belt 10 rotates to convey the packaged pet food to the receiving table 14.

[0033] Refer to Figures 1 to 10As shown in the figure, the telescopic component includes a housing 46, a telescopic spring 47, and a sliding column 48. The housing 46 is fixedly arranged at the top of the base. The sliding column 48 is slidably arranged inside the housing 46. The telescopic spring 47 is fixedly arranged between the top of the sliding column 48 and the inner top of the housing 46. One of the rollers 11 close to the base is rotatably connected to the sliding column 48 through a third rotating shaft 49. An avoidance groove for the vertical sliding of the third rotating shaft 49 is arranged on the outer wall of one of the vertical plates close to the housing 46. During the packaging and transportation of pet food by the special intelligent packaging equipment, sometimes the pet food will spill out. When the viscosity of the spilled pet food is very small, the cylinder 40 is started through the controller, so that its output end extends upward. Since its output end is fixedly connected to one of the sliding strips 42 through a push block 41, one of the rollers 11 close to the cylinder 40 is rotatably connected to the two sliding strips 42 through a second rotating shaft 44 and two bearings 43, so as to drive the roller 11 to rise vertically along with the two sliding strips 42. When rising, in order to ensure that the conveyor belt 10 always maintains a better tension, one of the rollers 11 close to the base will be vertically pulled by the roller 11 rising vertically and will rise vertically inside the housing 46 along with the sliding column 48, so as to compress the telescopic spring 47 through the sliding column 48 and change it from the initial state to the tightened state, realizing the adaptive adjustment of one of the rollers 11 close to the base, and then cooperating with the other two rollers 11 to tighten the conveyor belt 10, so that it always meets the standard for transporting products.

[0034] Working principle: This equipment belongs to an important machine in the field of special intelligent packaging equipment. The conveyor belt 10 plays a key role in the packaging production line. Specifically, when the pet food is packaged, it is necessary to discharge the packaged finished products through the conveyor belt 10. When discharging, first, the stepping motor 45 is started through the controller. Since its output end is fixedly connected to the end of the first rotating shaft 12, one of the rollers 11 close to the receiving table 14 is rotatably connected to the two vertical plates through the first rotating shaft 12. One of the rollers 11 close to the base is rotatably connected to the sliding column 48 through a third rotating shaft 49. The other roller 11 is rotatably connected to the two sliding strips 42 through a second rotating shaft 44 and two bearings 43. The three rollers 11 are sleeved by the conveyor belt 10, so as to make the conveyor belt 10 rotate and convey the packaged pet food to the receiving table 14.

[0035] This dedicated intelligent packaging device is equipped with a controller, and all the electrical devices on the device are electrically connected to the controller. In the initial state, the distance between the two baffles 13 is relatively small, which is convenient for limiting the position of the small and light pet food packaging boxes or packaging bags when the conveyor belt 10 operates. At this time, the receiving plate 26 is far from the conveyor belt 10. The small and light pet food packaging boxes or packaging bags fall onto the top of the receiving plate 26, and the receiving plate 26 rotates counterclockwise under the force, and under the action of several buffer springs 28, it buffers the small and light pet food packaging boxes or packaging bags to prevent them from directly falling to the ground and causing the packaging boxes or packaging bags to break, and avoid spilling the pet food. When the conveyor belt 10 conveys the large and heavy pet food packaging boxes or packaging bags, the bidirectional electric push rod 15 is started through the controller, so that both of its output ends extend, that is, its two output ends move away from each other. Since each L-shaped sliding rod 16 is slidably connected to the base, the two output ends of the bidirectional electric push rod 15 are respectively fixedly connected to the bottoms of the two L-shaped sliding rods 16, thereby driving the two L-shaped sliding rods 16 to move away from each other.

[0036] When the two L-shaped sliding rods 16 move away from each other, since the first sliding plate 17 is fixedly connected to the top of one of the L-shaped sliding rods 16, the two L-shaped plates 18 are both fixedly connected to one of the vertical plates, each inserting rod 19 is slidably connected to the L-shaped plate 18, and each first sliding plate 17 and one baffle 13 are respectively fixedly connected to the two ends of one inserting rod 19, thereby cooperating with the other first sliding component to drive the two baffles 13 to move away from each other, so that the distance between the two baffles 13 increases, thus facilitating the limiting of the large and heavy pet food packaging boxes or packaging bags conveyed on the conveyor belt 10 and improving the stability of conveying to the receiving table 14.

[0037] When the two baffles 13 move away from each other, that is, when the first sliding plate 17 drives one of the baffles 13 to slide towards one end close to the L-shaped plate 18, since the first sliding plate 17 is fixedly connected to the second sliding plate 22 through the traction rod 35 and the pull rope 36, and the second sliding plate 22 is slidably connected to the guide rod 38, under the limiting action of the limiting wheel 37, the second sliding plate 22 slides towards one end close to the receiving table 14 on the outer wall of the guide rod 38, thereby pressing the return spring 39 through the second sliding plate 22 to change it from the initial state to the tense state.

[0038] When the second sliding plate 22 slides towards one end close to the receiving table 14 on the outer wall of the guide rod 38, since the same side walls of the two wedge-shaped top blocks 23 are both fixedly connected to the second sliding plate 22, each wedge-shaped top block 23 is slidably connected to one of the chutes opened on the top of the mounting table 21 through the slider 24, thereby driving the two wedge-shaped top blocks 23 to slide towards one end close to the receiving table 14 on the top of the mounting table 21.

[0039] When the two wedge-shaped top blocks 23 slide towards one end close to the receiving table 14 at the top of the installation table 21, since the two connecting columns 34 are both fixedly connected to one end of the U-shaped plate 25, the ends of the two connecting columns 34 away from the U-shaped plate 25 are both fixedly connected to the connecting plate 32, the two wedge-shaped docking blocks 33 are both fixedly connected to the connecting plate 32, the hypotenuse of each wedge-shaped docking block 33 is in contact with the hypotenuse of one wedge-shaped top block 23, and the U-shaped plate 25 is slidably connected to the top of the base through four lifting blocks 29 and four limiting rods. Thus, when the two wedge-shaped top blocks 23 slide towards one end close to the receiving table 14 and abut against the two wedge-shaped docking blocks 33, the U-shaped plate 25 is driven to rise vertically at the top of the base, and then the receiving plate 26 thereon is driven to rise vertically and approach the conveyor belt 10, that is, the distance between the receiving plate 26 and the conveyor belt 10 is reduced, the gravitational potential energy caused by the falling of large-volume and heavy pet food packaging boxes or packaging bags is reduced, buffering is carried out, and it is prevented that the large-volume and heavy pet food packaging boxes or packaging bags directly contact the ground and are broken, playing a role in protecting the product and improving the flexibility of this special intelligent packaging equipment.

[0040] When the pet food packaging bag or packaging box is conveyed from the top of the conveyor belt 10 and falls onto the top of the receiving plate 26, since the receiving plate 26 is rotatably connected to the two vertical plates through the rotating rod 51, under the supporting and limiting action of the two limiting blocks 30, the receiving plate 26 will rotate counterclockwise. Under the limiting action of the limiting plate 27, several buffer springs 28 are compressed, causing them to change from the initial state to the taut state, realizing the unloading and buffering of the packaging box and packaging bag. At the same time, under the rotating action of the rotating plate, the pet food packaging bag or packaging box is automatically driven to slide from the top of the receiving plate 26 to the ground, realizing blanking. The two cylindrical sliding rods 31 and the two arc-shaped grooves play a role in limiting and guiding, ensuring the stable rotation of the receiving plate 26, and cooperating with several buffer springs 28 to realize stable blanking.

[0041] During the packaging and transportation of pet food by the special intelligent packaging equipment, sometimes pet food will spill out. When the viscosity of the spilled pet food is very small, the cylinder 40 is started through the controller, so that its output end extends upward. Since its output end is fixedly connected to one of the slide bars 42 through the push block 41, one of the rollers 11 close to the cylinder 40 is rotatably connected to the two slide bars 42 through the second rotating shaft 44 and two bearings 43, so as to drive the roller 11 to rise vertically along with the two slide bars 42. When rising, in order to ensure that the conveyor belt 10 always maintains a better tension force, one of the rollers 11 close to the base is tractioned by the roller 11 rising vertically upward and will rise vertically inside the housing 46 along with the sliding column 48, so as to compress the telescopic spring 47 through the sliding column 48 and make it change from the initial state to the taut state, realizing the adaptive adjustment of one of the rollers 11 close to the base, and then cooperating with the other two rollers 11 to tighten the conveyor belt 10 so that it always meets the standard of transporting products.

[0042] Embodiment 2: In order to prevent the pet food with a relatively high viscosity from leaking onto the surface of the conveyor belt 10 and not being discharged in time, which may breed bacteria, the present invention provides another technical solution; Referring to Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, a forward and reverse motor 50 is inserted on the outer wall of one of the vertical plates, and a rotating rod 51 is fixedly provided on its output end. A plurality of knocking rods 52 are equidistantly arranged on the outer wall of the rotating rod 51. A rubber pad 53 is fixedly provided at one end of each knocking rod 52 away from the rotating rod 51. A feeding chute 54 is fixedly provided between the two vertical plates near the receiving table 14. An anti-sticking paper (not shown in the figure) is attached to the outer wall of the feeding chute 54. A collection box 55 is provided on the top of the base. The feeding chute 54 faces the collection box 55. When the conveyor belt 10 is adjusted to an inclined state, the forward and reverse motor 50 is started through the controller, so that its output end first rotates counterclockwise and then clockwise, thereby driving the rotating rod 51 and the plurality of knocking rods 52 thereon to first rotate counterclockwise and then clockwise, and reciprocating in this way to knock on the outer wall of the conveyor belt 10, vibrating the pet food spilled on the surface of the conveyor belt 10, and conveying the vibrated pet food to the inside of the collection box 55 for temporary storage, which is convenient for recycling and avoids waste of resources. The anti-sticking paper is to prevent the pet food with a relatively high viscosity from adhering to the surface of the feeding chute 54 and not falling into the collection box 55, improving the collection effect. The design of the rubber pad 53 is to prevent damage to the conveyor belt 10 when the knocking rod 52 knocks on it, playing a role in protecting the conveyor belt 10 and improving the practicability of this special intelligent packaging equipment.
