Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] Combination Figures 1 to 6 The packaging production line 100 according to an embodiment of the present utility model includes: a conveying mechanism 10, a first monitoring mechanism 20, a blocking mechanism, and a control mechanism.

[0036] The conveying mechanism 10 is configured to convey material 70. The first monitoring mechanism 20 is configured to monitor the material status of the conveying mechanism 10. A blocking mechanism corresponds to the conveying mechanism 10, and has a blocking state and a releasing state. The blocking mechanism is configured to block material 70 in the blocking state and release material 70 in the releasing state. A control mechanism transmits signals with the first monitoring mechanism 20 and the blocking mechanism, and is configured to control the blocking mechanism according to the material status.

[0037] When the material state of the conveying mechanism 10 meets the first condition, the first monitoring mechanism 20 sends a signal back to the control mechanism so that the control mechanism controls the blocking mechanism to the blocking state, thereby blocking the material 70. This facilitates quick location and timely handling of problematic material 70, reducing the possibility of material 70 accumulating and colliding. When the material state meets the second condition (or does not meet the first condition), the first monitoring mechanism 20 sends a signal back to the control mechanism so that the control mechanism controls the blocking mechanism to the release state, preventing the blocking mechanism from obstructing the conveying of material 70.

[0038] The first condition may include material 70 being damaged, previous steps not being completed (e.g., not being marked with ink), or the spacing between materials 70 being too small. Additionally, the blocking mechanism can be configured to be either always in a releasing state or always in a blocking state.

[0039] For example, when the first monitoring mechanism 20 detects that the material status of the conveying mechanism 10 meets the first condition, such as material 70 being damaged, material 70 lacking identification, or the distance between two adjacent materials 70 being too close, the first monitoring mechanism 20 sends a signal back to the control mechanism (not shown in the attached figure) so that the control mechanism controls the blocking mechanism to a blocking state, thereby blocking the material 70. This facilitates quick location and timely handling of problematic material 70, reduces the risk of material 70 accumulation and collision, and improves the production efficiency of the packaging production line 100. After the problematic material 70 is handled, the blocking mechanism can be in a release state so that the material 70 can continue to be conveyed on the conveying mechanism 10. When the material status does not meet the first condition, the first monitoring mechanism 20 sends a signal back to the control mechanism so that the control mechanism controls the blocking mechanism to switch to a release state, or keeps the blocking mechanism in a release state, to prevent the blocking mechanism from obstructing the conveying of material 70.

[0040] According to the embodiment of this utility model, the packaging production line 100 monitors the material status through the first monitoring mechanism 20 and controls the blocking mechanism based on the material status to effectively block and position the material 70 on the conveying mechanism 10, reducing the possibility of material 70 accumulation and collision, and achieving precise control of the material 70 on the packaging production line 100. At the same time, it reduces the labor intensity of operators and realizes the automated operation of the packaging production line 100. In addition, through the action of the blocking mechanism, the flow of material 70 can be blocked in a timely manner at a specific position to ensure that the material 70 is processed and handled according to the predetermined production process. The blocking mechanism can respond quickly and accurately execute the blocking action to avoid production interruption and chaos caused by disorderly flow of material 70, ensure the integrity of material 70 and the stability of material 70 transportation, thereby improving the operating efficiency of the packaging production line 100.

[0041] According to the packaging production line 100 of this utility model embodiment, the specific components and structure of the blocking mechanism include, but are not limited to, the following embodiments.

[0042] Implementation Method 1 Combination Figure 1 and Figure 3 In some embodiments, the blocking mechanism includes a first limiting part 31, a second limiting part 32 and a driving part 33. The driving part 33 is configured to adjust the minimum size value of the first limiting part 31 and the second limiting part 32 along the width direction of the conveying mechanism 10. The minimum size value L1 of the first limiting part 31 and the second limiting part 32 in the blocking state is less than the minimum size value L2 in the releasing state. In the blocking state, the drive unit 33 reduces the minimum size of the first limiting part 31 and the second limiting part 32 along the width direction of the conveying mechanism 10, so that the first limiting part 31 and the second limiting part 32 restrict the movement of the material 70, ensuring that the blocking mechanism prevents the flow of the material 70 in the blocking state, facilitating timely detection and handling of problematic material 70, avoiding production interruptions and chaos caused by disorderly flow of material 70, ensuring the integrity of material 70 and the stability of material 70 transportation, and improving the operating efficiency of the packaging production line 100; in the releasing state, the drive unit 33 increases the minimum size of the first limiting part 31 and the second limiting part 32 along the width direction of the conveying mechanism 10, so that the first limiting part 31 and the second limiting part 32 release the restriction on the material 70, and the material 70 can be conveyed on the conveying mechanism 10.

[0043] For example, the width direction of the conveying mechanism 10 can be referenced Figure 1 The forward and backward directions, and the conveying direction of the conveying mechanism 10 can be referenced. Figure 1 In the left-right direction, the material 70 can move from right to left on the conveying mechanism 10; the minimum size value L1 in the blocked state is as follows: Figure 1 As shown, the minimum size value L2 in the release state is as follows: Figure 2 As shown, the minimum size value L1 in the blocking state is less than the minimum size value L2 in the releasing state, ensuring that the first limiting part 31 and the second limiting part 32 restrict the movement of the material 70 in the blocking state and release the restriction on the material 70 in the releasing state.

[0044] The first limiting part 31 can be located at the rear of the conveying mechanism 10, and the second limiting part 32 can be located at the front of the conveying mechanism 10. In the blocking state, the first limiting part 31 and the second limiting part 32 can move closer to each other in the front-back direction and jointly restrict the movement of the material 70. The material 70 is stopped at the current position, and the conveying mechanism 10 cannot drive the material 70 to continue to move to the right, ensuring that the blocking mechanism prevents the flow of the material 70 in the blocking state. In the releasing state, the first limiting part 31 and the second limiting part 32 can move further away from each other in the front-back direction and release the restriction on the movement of the material 70. The conveying mechanism 10 can drive the material 70 to continue to move to the right so that the material 70 can be conveyed on the conveying mechanism 10.

[0045] In some embodiments, at least one of the first limiting part 31 and the second limiting part 32 stops the material 70 in front of it along the conveying direction in the blocking state. Specifically, the first limiting part 31 can stop the material 70 in front of it along the conveying direction in the blocking state; or, the second limiting part 32 can stop the material 70 in front of it along the conveying direction in the blocking state; or, the first limiting part 31 and the second limiting part 32 can stop the material 70 in front of it along the conveying direction in the blocking state, so as to prevent the material 70 from continuing to move along the conveying direction on the conveying mechanism 10, effectively blocking and positioning the material 70 on the conveying mechanism 10, reducing the possibility of material 70 accumulating or colliding, and realizing precise control of the material 70 on the packaging production line 100.

[0046] For example, the conveying direction of the conveying mechanism 10 can be referenced Figure 1 In the left-right direction, the material 70 can move from right to left on the conveying mechanism 10. The front of the material 70 along the conveying direction can be referenced. Figure 1 The material 70 is positioned to the left of the conveying mechanism 10. The first limiting part 31 can be located at the rear of the conveying mechanism 10, and the second limiting part 32 can be located at the front of the conveying mechanism 10. In the blocking state, the first limiting part 31 can extend from the rear to the front and stop the material 70 to the left; or, in the blocking state, the second limiting part 32 can extend from the front to the rear and stop the material 70 to the left; or, in the blocking state, the first limiting part 31 can extend from the rear to the front, and the second limiting part 32 can extend from the front to the rear. The first limiting part 31 and the second limiting part 32 can simultaneously stop the material 70 to the left, and the material 70 is stopped at its current position to prevent the material 70 from continuing to move along the conveying direction on the conveying mechanism 10. This effectively blocks and positions the material 70 on the conveying mechanism 10, reduces the possibility of material 70 accumulating or colliding, and achieves precise control of the material 70 on the packaging production line 100.

[0047] In other embodiments, in the blocking state, the first limiting part 31 and the second limiting part 32 are configured to clamp the material 70 to restrict the material 70 from continuing to move on the conveying mechanism 10. By clamping the material 70 with the blocking mechanism, the flow of the material 70 can be blocked in a timely manner at a specific position, ensuring that the material 70 is processed and handled according to the predetermined production process. Specifically, in the blocking state, the first limiting part 31 and the second limiting part 32 can clamp the material 70 on both sides in the front-back direction, and the material 70 is stopped at the current position to prevent the conveying mechanism 10 from continuing to move the material 70. In the releasing state, the first limiting part 31 and the second limiting part 32 can release the clamping on both sides of the material 70 in the front-back direction, and the conveying mechanism 10 can continue to move the material 70 so that the material 70 can be conveyed on the conveying mechanism 10.

[0048] Combination Figure 1 and Figure 3 In some embodiments, the first limiting part 31 includes a side rail 311, and the second limiting part 32 includes a first blocking part 321. The side rail 311 and the first blocking part 321 are distributed along the width direction of the conveying mechanism 10, and the driving part 33 is connected to the first blocking part 321. When the blocking mechanism changes from the release state to the blocking state, the driving part 33 drives the first blocking part 321 to move and reduces the size between the side rail 311 and the first blocking part 321, so that the first blocking part 321 and the side rail 311 obstruct the flow of material 70 in the blocking state, which facilitates timely detection and handling of problematic material 70 and improves the production efficiency of the packaging production line 100. When the blocking mechanism changes from the blocking state to the release state, the driving part 33 drives the first blocking part 321 to move and increases the size between the side rail 311 and the first blocking part 321, so that the conveying mechanism 10 drives the material 70 to move.

[0049] For example, the first blocking part 321 can be provided on one side of the conveying mechanism 10 in the front-back direction, and the side rail 311 can be fixedly connected to the other side of the conveying mechanism 10 in the front-back direction. The side rail 311 can be opposite to the first blocking part 321 in the front-back direction of the conveying mechanism 10. When the first monitoring mechanism 20 detects that the material state of the conveying mechanism 10 meets the first condition, the blocking mechanism can switch from the release state to the blocking state, and the driving part 33 drives the first blocking part 321 to reduce the size of the first blocking part 321 and the side rail 311 in the front-back direction. The first blocking part 321 can stop the material 70 on the left side, or the first blocking part 321 can stop the material 70 on the side edge, or the first blocking part 321 can abut against the front side of the material 70, and the side rail 311 can abut against the rear side of the material 70, so that the first blocking part 321 and the side rail 311 restrict the movement of the material 70, and the material 70 is stopped at the current position, ensuring that the blocking mechanism prevents the flow of the material 70 in the blocking state, which facilitates timely detection and handling of problematic material 70, and ensures the reliability and stability of the transportation of material 70.

[0050] In addition, when the first monitoring mechanism 20 detects that the material state of the conveying mechanism 10 does not meet the first condition, the blocking mechanism can switch from the blocking state to the releasing state. The driving unit 33 drives the first blocking part 321 to increase the size of the first blocking part 321 and the side rail 311 in the front-back direction. The first blocking part 321 and the side rail 311 release the restriction on the material 70, and the conveying mechanism 10 can drive the material 70 to move so that the material 70 can be conveyed on the conveying mechanism 10.

[0051] Combination Figure 6 At least a portion of the first limiting part 31 is height-adjustable relative to the conveying mechanism 10. Optionally, the first limiting part 31 may further include a baffle 312, which may be disposed on the side of the conveying mechanism 10. The baffle 312 can be adjusted in the vertical direction relative to the conveying mechanism 10 according to the height of the material 70. The baffle 312 can also be used to block the material 70. In the blocking state, the baffle 312 can abut against the rear side of the material 70, further ensuring that the blocking mechanism prevents the flow of the material 70 in the blocking state.

[0052] In other embodiments, the first limiting part 31 includes a second blocking part, and the second limiting part 32 includes a third blocking part. The second and third blocking parts are distributed along the width direction of the conveying mechanism 10, and the driving part 33 is connected to the second and third blocking parts. When the blocking mechanism switches from the release state to the blocking state, the driving part 33 drives the second and third blocking parts to move and reduces the size between the second and third blocking parts, so that the second and third blocking parts impede the flow of material 70 in the blocking state, which facilitates timely detection and handling of problematic material 70 and improves the production efficiency of the packaging production line 100. When the blocking mechanism switches from the blocking state to the release state, the driving part 33 drives the second and third blocking parts to move and increases the size between the second and third blocking parts, so that the conveying mechanism 10 drives the material 70 to move.

[0053] For example, the second blocking part can be provided on one side of the conveying mechanism 10 along the front-back direction, and the third blocking part can be provided on the other side of the conveying mechanism 10 along the front-back direction. The second blocking part and the third blocking part can be opposite each other along the front-back direction of the conveying mechanism 10. When the first monitoring mechanism 20 detects that the material state of the conveying mechanism 10 meets the first condition, the blocking mechanism can switch from the release state to the blocking state, and the driving unit 33 drives the second blocking part and the third blocking part to reduce the size of the second blocking part and the third blocking part along the front-back direction.

[0054] Taking an example where the second blocking part is located on the front side of the conveying mechanism 10 and the third blocking part is located on the rear side of the conveying mechanism 10, the second blocking part can stop on the left side of the material 70, or the second blocking part can stop on the front edge of the material 70, or the second blocking part can abut against the front side of the material 70; at the same time, the third blocking part can stop on the left side of the material 70, or the third blocking part can stop on the rear edge of the material 70, or the third blocking part can abut against the rear side of the material 70, so that the second and third blocking parts restrict the movement of the material 70, and the material 70 is stopped at its current position, ensuring that the blocking mechanism prevents the flow of the material 70 in the blocking state, which facilitates timely detection and handling of problematic material 70, and ensures the reliability and stability of the material 70 transportation. Of course, the third blocking part can also be located on the front side of the conveying mechanism 10, and the second blocking part can be located on the rear side of the conveying mechanism 10.

[0055] In addition, when the first monitoring mechanism 20 detects that the material state of the conveying mechanism 10 does not meet the first condition, the blocking mechanism can switch from the blocking state to the releasing state. The driving unit 33 drives the second blocking part and the third blocking part to increase the size of the second blocking part and the third blocking part in the front-back direction. The second blocking part and the third blocking part release the restriction on the material 70, and the conveying mechanism 10 can drive the material 70 to move so that the material 70 is conveyed on the conveying mechanism 10.

[0056] Combination Figures 1 to 3 In some embodiments, the second limiting portion 32 includes a first wedge-shaped inclined surface 322. The first wedge-shaped inclined surface 322 is configured as an arc that slopes from the first end of the second limiting portion 32 toward the first limiting portion 31 along the conveying direction of the conveying mechanism 10. This prevents the first wedge-shaped inclined surface 322 from obstructing the transport of the material 70 in the release state. At the same time, in the blocking state, the first wedge-shaped inclined surface 322 is used to abut against the edge of the material 70 to restrict the movement of the material 70. The first wedge-shaped inclined surface 322 can be inclined from front to back to the left to prevent it from obstructing the transport of the material 70 in the release state. Furthermore, the first wedge-shaped inclined surface 322 is provided with a first limiting groove 3221. In the blocking state, the side edge of the material 70 can abut against the wall of the first limiting groove 3221, so that the material 70 is blocked and stopped at the current position.

[0057] In some embodiments, the second limiting portion 32 includes a second wedge-shaped inclined surface 323, which is configured to extend obliquely to the second end of the second limiting portion 32 in a direction away from the first limiting portion 31 along the conveying direction of the conveying mechanism 10. This prevents the second wedge-shaped inclined surface 323 from obstructing the transport of the material 70 in the release state, while in the blocking state, the second wedge-shaped inclined surface 323 abuts against the edge of the material 70 to restrict the movement of the material 70. The second wedge-shaped inclined surface 323 can be inclined from front to back to the right to prevent it from obstructing the transport of the material 70 in the release state. Furthermore, the second wedge-shaped inclined surface 323 is provided with a second limiting groove. In the blocking state, the side edge of the material 70 can abut against the wall of the second limiting groove, thus blocking and stopping the material 70 at its current position.

[0058] Preferably, in the packaging production line 100 of this utility model embodiment, the wall surface of the first limiting groove 3221 of the first wedge-shaped inclined surface 322 abuts against the left edge of the material 70, so that the material 70 is blocked and stopped at the current position, reducing the risk of the material 70 being squeezed and deformed by the second limiting part 32. However, this is not a limitation on the scope of protection of this utility model.

[0059] Combination Figure 4In some embodiments, at least one of the first limiting part 31 and the second limiting part 32 includes a buffer structure 34, which is used to abut against the material 70 in the blocking state. Specifically, the first limiting part 31 may include the buffer structure 34; or, the second limiting part 32 may include the buffer structure 34; or, both the first limiting part 31 and the second limiting part 32 may include the buffer structure 34. By providing the buffer structure 34, the friction and buffering function of the first limiting part 31 and the second limiting part 32 on the material 70 are increased, which can reduce the impact and collision of the first limiting part 31 and the second limiting part 32 on the material 70, improve the stability and operating efficiency of the first limiting part 31 and the second limiting part 32 in blocking the material 70, and at the same time reduce the vibration and noise when the first limiting part 31 and the second limiting part 32 block the material 70, thereby reducing the cost loss and failure efficiency of the packaging production line 100.

[0060] Optionally, at least one of the first limiting portion 31 and the second limiting portion 32 has a protrusion array on its surface opposite to the material 70. Specifically, the surface of the first limiting portion 31 opposite to the material 70 may have a protrusion array; or, the surface of the second limiting portion 32 opposite to the material 70 may have a protrusion array; or, both the surfaces of the first limiting portion 31 and the second limiting portion 32 opposite to the material 70 may have a protrusion array. The protrusion array can be used to increase the friction between the first limiting portion 31 and the second limiting portion 32 and the material 70, preventing the material 70 with a high center of gravity from sliding sideways and improving the stability of the first limiting portion 31 and the second limiting portion 32 in blocking the material 70.

[0061] Optionally, at least one of the first limiting part 31 and the second limiting part 32 is provided with a vacuum suction hole for adsorbing the material 70. Specifically, the first limiting part 31 may be provided with a vacuum suction hole for adsorbing the material 70; or, the second limiting part 32 may be provided with a vacuum suction hole for adsorbing the material 70; or, both the first limiting part 31 and the second limiting part 32 may be provided with vacuum suction holes for adsorbing the material 70. The vacuum suction hole adsorbs the material 70 onto its surface by generating a vacuum. When the vacuum suction hole contacts the surface of the material 70, the internal air is extracted, forming a vacuum state, thereby generating an adsorption force to adsorb the material 70. This improves the reliability of the first limiting part 31 and the second limiting part 32 in restricting and blocking the material 70, preventing the material 70 from escaping from the first limiting part 31 and the second limiting part 32 under blocked conditions.

[0062] Preferably, the buffer structure 34 can be a silicone pad with a hardness of 60 Shore A. A silicone pad with a hardness of 60 Shore A can withstand greater pressure and is not easily deformed. The silicone pad can also be provided with vacuum suction holes, which can form negative pressure and adsorb material 70 in a short time, thereby improving the stability of the first limiting part 31 and the second limiting part 32 in blocking material 70. Of course, the surface of the silicone pad that contacts the material 70 can be set as a plane, and the thickness of the silicone pad can be set as 8 mm, for materials 70 that are not allowed to be adsorbed on the surface (such as materials 70 with a surface coating).

[0063] Combination Figure 1 and Figure 3 In some embodiments, the drive unit 33 includes a cylinder 331, the piston rod 332 of the cylinder 331 is connected to the first limiting part 31 or the second limiting part 32, the piston rod 332 of the cylinder 331 extends in the blocking state, and the piston rod 332 of the cylinder 331 retracts in the releasing state. The piston rod 332 of the cylinder 331 can be connected to the first limiting part 31. In the blocking state, the piston rod 332 of the cylinder 331 extends and drives the first limiting part 31 to move towards the second limiting part 32, reducing the distance between the first limiting part 31 and the second limiting part 32 so that the first limiting part 31 and the second limiting part 32 can block the material 70. In the releasing state, the piston rod 332 of the cylinder 331 retracts and drives the first limiting part 31 to move away from the second limiting part 32, increasing the distance between the first limiting part 31 and the second limiting part 32 so that the first limiting part 31 and the second limiting part 32 can release the restriction on the material 70.

[0064] Of course, the piston rod 332 of the cylinder 331 can also be connected to the second limiting part 32. In the blocking state, the piston rod 332 of the cylinder 331 extends and drives the second limiting part 32 to move towards the first limiting part 31, reducing the distance between the first limiting part 31 and the second limiting part 32 so that the first limiting part 31 and the second limiting part 32 can block the material 70. In the releasing state, the piston rod 332 of the cylinder 331 retracts and drives the second limiting part 32 to move away from the first limiting part 31, increasing the distance between the first limiting part 31 and the second limiting part 32 so that the first limiting part 31 and the second limiting part 32 can release the restriction on the material 70.

[0065] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5In some embodiments, the blocking mechanism further includes a reversing valve 35 and a power source 36. The reversing valve 35 is connected to a cylinder 331; the power source 36 is connected to the reversing valve 35 and is used to drive the cylinder 331 to extend and retract. The power source 36 includes a negative pressure source or a pneumatic source. When the power source 36 drives the cylinder 331 to extend through the reversing valve 35, the cylinder 331 abuts against the material 70 and blocks the material 70 from continuing to move along the conveying direction. When the power source 36 drives the cylinder 331 to retract through the reversing valve 35, the cylinder 331 separates from the material 70, the cylinder 331 releases its obstruction of the material 70, and the material 70 continues to move along the conveying direction.

[0066] For example, cylinder 331 may contain piston rod 332 and piston 333. Piston 333 can divide the interior of cylinder 331 into a first chamber and a second chamber that are spaced apart from each other. Piston rod 332 can extend and retract in the second chamber. The first chamber can be a rodless chamber. The first reversing valve 35 may have a first port A1, a second port B1, a third port C1, a fourth port D1, and a fifth port E1. The fourth port D1 can connect to the first chamber, and the fifth port E1 can connect to the second chamber. The first port A1 and the third port C1 are used for air return, and the second port B1 can be connected to the power source 36.

[0067] Furthermore, taking the power source 36, which includes a pneumatic source and a piston rod 332 connected to the cylinder 331 via a second limiting part 32, as an example, the first reversing valve 35 includes a first state and a second state. In the first state, the first interface A1 is closed, the second interface B1 is connected to the fourth interface D1, the third interface C1 can be connected to the external environment, and the third interface C1 is connected to the fifth interface E1. The power source 36 can pump gas into the first chamber through the second interface B1 and the fourth interface D1. The gas in the first chamber drives the piston 333 and the piston rod 332 to move from front to back, so that the piston rod 332 can drive the second limiting part 32 to move from front to back until the second limiting part 32 abuts against the material 70, preventing the material 70 from continuing to move along the conveying direction. The gas in the second chamber can be directly discharged into the external environment.

[0068] In the second state, the first interface A1 is connected to the fourth interface D1, and the first interface A1 can also be connected to the external environment. The second interface B1 is connected to the fifth interface E1, and the third interface C1 is cut off. The power source 36 can pump gas into the second chamber through the second interface B1 and the fifth interface E1. The gas drives the piston 333 and the piston rod 332 to move from back to front in the second chamber, so that the piston rod 332 can drive the second limiting part 32 to move from back to front. The second limiting part 32 can release the obstruction to the material 70, and the material 70 continues to move along the conveying direction.

[0069] Alternatively, the power source 36 can also be a negative pressure source. The negative pressure source can remove air from the first or second chamber using a vacuum generator or vacuum pump, creating a vacuum environment. Under the influence of atmospheric pressure difference, this environment drives the piston 333 and piston rod 332 of the cylinder 331 to extend and retract. The negative pressure source has advantages such as small size, simple structure, easy installation, fast response, and low maintenance costs, making it suitable for intermittent, low-flow vacuum applications.

[0070] Optionally, cylinder 331 can be a dual-axis cylinder 331. The dual-axis cylinder 331 has a scientifically designed structure, equipped with two guide shafts and a floating shaft plate, which can effectively reduce the influence of vibration and lateral force, thereby improving accuracy and stability. At the same time, the forces on both sides of the dual-axis cylinder 331 are balanced, the movement is smooth, and it can provide consistent thrust, reduce vibration, and improve positioning accuracy, making it especially suitable for automation systems and high-precision tasks.

[0071] Implementation Method 2 Combination Figure 4 and Figure 5 In some embodiments, the blocking mechanism includes a third limiting part 37. In the blocking state, at least a portion of the third limiting part 37 is disposed on the conveying trajectory of the material 70 to block the material 70 conveyed by the conveying mechanism 10. In the releasing state, the third limiting part 37 is offset from the conveying trajectory of the material 70 to allow the material 70 conveyed by the conveying mechanism 10 to pass. The conveying trajectory of the material 70 can extend in the left-right direction, and the third limiting part 37 can move in the front-back direction. The left-right and front-back directions can be referenced. Figure 4 and Figure 5 The left-right and front-back directions.

[0072] Furthermore, in the blocking state, the third limiting part 37 can move backward, and at least a portion of the third limiting part 37 can be located on the conveying trajectory of the material 70. The third limiting part 37 can abut against the side of the material 70 in the front-back direction to restrict the material 70 from continuing to move on the conveying mechanism 10, thereby realizing the blocking effect of the blocking mechanism on the material 70. In the releasing state, the third limiting part 37 can move forward, and the third limiting part 37 can be offset from the conveying trajectory of the material 70. The third limiting part 37 can move away from the material 70 in the front-back direction to release the blocking and restriction of the material 70 by the third limiting part 37, and the conveying mechanism 10 can continue to drive the material 70 to move.

[0073] Implementation Method 3 In some embodiments, the blocking mechanism includes a fourth limiting part. In the blocking state, the fourth limiting part has an adsorption force for the material 70, improving the reliability and stability of the fourth limiting part in blocking the material 70 and preventing the material 70 from escaping from the fourth limiting part in the blocking state. The fourth limiting part may be equipped with an adsorption structure, such as a vacuum suction hole, a suction cup, or a vacuum generator. The principle behind the adsorption force generated by the fourth limiting part is as follows: a closed or semi-closed area (sealed cavity) is created between the fourth limiting part and the surface of the material 70. The pressure within this area is reduced by methods such as evacuation or degassing, making it much lower than the atmospheric pressure in the external environment. The high pressure of the external environment then generates an adsorption force on the edge of the sealed cavity, allowing the fourth limiting part to adsorb the surface of the material 70, ensuring that the fourth limiting part stably blocks the material 70.

[0074] The above description only describes some embodiments of the present invention, but it is not intended to limit the scope of protection of the present invention.

[0075] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the first monitoring mechanism 20 includes an image recognition module, a distance sensor or a position sensor, which facilitates the first monitoring mechanism 20 to monitor the material status of the conveying mechanism 10 and transmit control signals to the control mechanism, thereby controlling the blocking mechanism to switch between blocking and releasing states.

[0076] Optionally, the first monitoring unit 20 may include an image recognition module. Image processing and recognition technology refers to the technology of converting an image of the external world into computer-accessible data and then recognizing it. The image recognition module learns and forms various image features required for recognition, and correctly distinguishes the category of the image to be recognized based on these features. Specifically, the image recognition module can determine whether the material 70 is in a good or bad state through processes such as image acquisition, image preprocessing, feature extraction, and image recognition, and transmit electrical signals to the control mechanism so that the control mechanism can control whether the blocking mechanism blocks the material 70 and whether the conveying mechanism 10 stops operating.

[0077] Compared to manual judgment of the material 70 by staff, judging the state of the material 70 by the image recognition module can help staff to detect defective materials in a timely manner, reduce the labor intensity of staff, increase the speed of monitoring the material 70, reduce the possibility of defective material 70 flowing into the production line, and improve the production efficiency of the packaging production line 100.

[0078] Optionally, the first monitoring mechanism 20 may further include a power supply 21, which has a first circuit, a second circuit, and a third circuit. The power supply 21 can be connected to the first monitoring mechanism 20 through the first circuit and the second circuit, and supply power to the first monitoring mechanism 20. The first circuit can be supplied with 24V voltage, and the second circuit can be grounded. The third circuit can process the output signal of the first monitoring mechanism 20 through the control mechanism. The processed signal can be sent to the solenoid valve of the blocking mechanism to enable the first monitoring mechanism 20 to monitor the material status of the conveying mechanism 10 and control the blocking mechanism to switch between blocking and releasing states according to the material status.

[0079] In some examples, the control mechanism is configured to determine whether the material status of the conveying mechanism 10 is defective or good based on the identification result of the first monitoring mechanism 20. A defective status refers to situations such as material 70 being damaged or lacking labeling, while a good status refers to situations such as material 70 having intact packaging and complete labeling. When the material status is defective, the control mechanism is set to block the material. If the first monitoring mechanism 20 detects that the material status of the conveying mechanism 10 is defective, the blocking mechanism can promptly block the defective material 70, preventing it from flowing into the packaging production line 100.

[0080] For example, the first monitoring mechanism 20 can monitor the material status of the conveying mechanism 10 and determine whether the material status is good or bad. If the material status is good, the blocking mechanism is in the release state, and the conveying mechanism 10 continues to transport the material 70; if the material status is bad, the first monitoring mechanism 20 sends a signal back to the control mechanism, and the control mechanism drives the blocking mechanism to switch to the blocking state. The blocking mechanism can promptly block the bad material 70, and at the same time, the control mechanism can control the conveying mechanism 10 to stop running. This enables the blocking mechanism to promptly block and intercept the bad material 70 and prevent the material 70 upstream of the conveying mechanism 10 from continuing to move in the conveying direction. This makes it easier for staff to promptly detect and handle the bad material 70, reducing the input of bad material 70 into the packaging production line 100 and improving the stability and reliability of the packaging production line 100.

[0081] Optionally, the first monitoring unit 20 may also include a distance sensor for sensing the distance between itself and an object to perform a preset function. Distance sensors can be categorized into various types based on their working principles, such as optical distance sensors, infrared distance sensors, and ultrasonic distance sensors. For example, the working principle of an infrared distance sensor is as follows: it has an infrared emitting tube and an infrared receiving tube. When the infrared light emitted by the emitting tube is received by the receiving tube, it indicates a close distance; conversely, when the receiving tube does not receive the infrared light emitted by the emitting tube, it indicates a far distance. Other types of distance sensors operate on similar principles to infrared distance sensors, determining distance through the emission and reception of certain substances. The emitted substance can be ultrasound, light pulses, etc.

[0082] The first monitoring mechanism 20 can monitor the distance parameters between itself and the materials 70 within the monitoring area. If the difference between the distance parameters of two adjacent materials 70 and the first monitoring mechanism 20 is small, the first monitoring mechanism 20 can send a signal back to the control mechanism, causing the control mechanism to switch the blocking mechanism to a blocking state. This blocks the relatively rearward material 70 along the conveying direction of the conveying mechanism 10, increasing the distance between two adjacent materials 70 and ensuring a larger distance between them. This prevents material accumulation and collisions, improving the stability and reliability of the packaging production line 100. If the difference between the distance parameters of two adjacent materials 70 and the first monitoring mechanism 20 is large, the first monitoring mechanism 20 will not send a signal back to the control mechanism, and the blocking mechanism will be in a releasing state, facilitating the conveying of the materials 70.

[0083] Optionally, the first monitoring mechanism 20 may further include a position sensor, which can be used to monitor the position of the material 70 within the monitoring area. That is, the position sensor is referenced to or from a fixed point or position, and then provides position feedback. The first monitoring mechanism 20 can monitor the position of the material 70 within the monitoring area. If the first monitoring mechanism 20 detects that two adjacent material 70s are too close together, for example, the distance between the two material 70s is less than 150 cm, the first monitoring mechanism 20 can send a signal back to the control mechanism, causing the control mechanism to switch the blocking mechanism to a blocking state. This blocks the relatively rearward material 70 along the conveying direction of the conveying mechanism 10, increasing the distance between the two adjacent material 70s and ensuring a larger distance between them. This avoids material accumulation and collisions, improving the stability and reliability of the packaging production line 100. If the first monitoring mechanism 20 detects that two adjacent material 70s are far apart, for example, the distance between the two material 70s is greater than 200 cm, the blocking mechanism switches to a releasing state, facilitating the conveying of the material 70s.

[0084] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the blocking mechanism is located downstream of the monitoring area of ​​the first monitoring mechanism 20 along the conveying direction of the conveying mechanism 10, so that the blocking mechanism can promptly block the material 70 in the blocking state. If the first monitoring mechanism 20 detects that the material state of the conveying mechanism 10 is defective, the blocking mechanism can promptly block the defective material 70 downstream of the monitoring area of ​​the first monitoring mechanism 20, and prevent the material 70 upstream of the conveying mechanism 10 from continuing to move along the conveying direction, avoiding the accumulation and collision of the material 70, and improving the production efficiency of the packaging production line 100.

[0085] For example, the conveying direction can be referenced. Figure 1 In the left-right direction, the conveying mechanism 10 can drive the material 70 to move from right to left. The blocking mechanism is located downstream of the monitoring area of ​​the first monitoring mechanism 20 along the conveying direction of the conveying mechanism 10. That is to say, the blocking mechanism can be located on the left side of the monitoring area of ​​the first monitoring mechanism 20. If the first monitoring mechanism 20 detects that the state of the material 70 is undesirable, the blocking mechanism is downstream of the monitoring area of ​​the first monitoring mechanism 20 and can promptly prevent the undesirable material 70 from continuing to move to the left.

[0086] The first monitoring mechanism 20 monitors the material status of the conveying mechanism 10 and determines whether the material 70 is in a good or bad state. If the material 70 is in a good state, the blocking mechanism switches to a release state, and the conveying mechanism 10 continues to transport the material 70. If the material 70 is in a bad state, the first monitoring mechanism 20 can transmit a signal to the control mechanism, which controls the blocking mechanism to switch to a blocking state. When the material 70 in a bad state moves to the side of the blocking mechanism, the edge of the material 70 abuts against the blocking mechanism, thus blocking the material 70. Alternatively, when the material 70 in a bad state moves to a position opposite the blocking mechanism in the front-back direction, the first monitoring mechanism 20 can transmit a signal to the control mechanism, which controls the blocking mechanism to switch to a blocking state. The blocking mechanism abuts against the side of the material 70 in the front-back direction, thus blocking the material 70.

[0087] In addition, the first monitoring mechanism 20 can also monitor the distance between two adjacent materials 70 on the conveying mechanism 10. If two adjacent materials 70 on the conveying mechanism 10 are too close, for example, the distance between the two materials 70 is less than 150 cm, the first monitoring mechanism 20 can transmit a signal to the control mechanism. The control mechanism controls the blocking mechanism to switch to the blocking state. When the material 70 that is relatively far back moves to the side of the blocking mechanism along the conveying direction of the conveying mechanism 10, the edge of the material 70 abuts against the blocking mechanism, thus blocking the material 70 behind it. Alternatively, when the material 70 that is relatively far back moves to a position opposite to the blocking mechanism in the front-back direction, the first monitoring mechanism 20 can transmit a signal to the control mechanism. The control mechanism controls the blocking mechanism to switch to the blocking state. The blocking mechanism abuts against the side of the material 70 in the front-back direction, thus blocking the material 70 behind it. This increases the distance between two adjacent materials 70 and prevents the materials 70 from colliding or piling up. If two adjacent materials 70 on the conveying mechanism 10 are far apart, for example, the distance between the two materials 70 is greater than 200 cm, the blocking mechanism can be switched to the release state to facilitate the conveying of the materials 70.

[0088] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5In some embodiments, the control mechanism further includes a control button 60, which is configured to control the start and stop of the conveying mechanism 10, allowing operators to control the start and stop of the conveying mechanism 10 via the control button 60. The control mechanism can also transmit signals to the conveying mechanism 10. When the first monitoring mechanism 20 detects that the material state of the conveying mechanism 10 is defective, after the material 70 has completely left the monitoring area of ​​the first monitoring mechanism 20, the first monitoring mechanism 20 can send a signal to the control mechanism, causing the control mechanism to stop the conveying mechanism 10 and control the blocking mechanism to switch to a blocking state. The blocking mechanism can block and locate the defective material 70, allowing operators to quickly identify and promptly handle the defective material 70. Simultaneously, the material 70 upstream of the conveying mechanism 10 will not continue to move along the conveying direction, preventing the accumulation and collision of material 70 caused by the continued movement of material 70 upstream of the conveying mechanism 10 along the conveying direction. After the staff has processed the defective material 70, the staff can restart the conveyor mechanism 10 by controlling the button 60, so that the conveyor mechanism 10 can transport the material 70 and reduce the flow of defective material 70 into the packaging production line 100, thereby reducing the cost loss of the packaging production line 100.

[0089] Of course, the packaging production line 100 may also include a second monitoring mechanism 50. The second monitoring mechanism 50 can transmit signals with the control mechanism. When the first monitoring mechanism 20 detects that the material state of the conveying mechanism 10 is defective, when the material 70 moves to the position of the second monitoring mechanism 50 relative to the width direction of the conveying mechanism 10, the second monitoring mechanism 50 can transmit a signal to the control mechanism, so that the control mechanism can control the conveying mechanism 10 to stop running and control the blocking mechanism to change from the release state to the blocking state. The blocking mechanism can block and locate the defective material 70.

[0090] In addition, when the packaging production line 100 needs to change materials 70 or perform equipment maintenance, the staff can control the start and stop of the conveyor mechanism 10 through the control button 60, which facilitates manual control of the conveyor mechanism 10.

[0091] Combination Figure 6In some embodiments, the packaging production line 100 further includes a fixed bracket 41 and a quick-release bracket 42. The fixed bracket 41 is located on the side of the conveying mechanism 10. The quick-release bracket 42 connects the blocking mechanism and the fixed bracket 41. The quick-release bracket 42 is configured to adjust the position of the blocking mechanism in the vertical direction, reducing the difficulty of adjusting the blocking mechanism and facilitating the blocking mechanism to block materials 70 of different heights. This improves the adaptability of the blocking mechanism to different materials 70, while shortening the changeover time of the packaging production line 100 and reducing the changeover cost of the packaging production line 100. The quick-release bracket 42 can be rotatably connected to the fixed bracket 41, and the blocking mechanism can be fixedly connected to the quick-release bracket 42. The height of the blocking mechanism in the vertical direction can be adjusted by adjusting the rotation angle of the quick-release bracket 42. When the height of the material 70 is low, the rotation angle of the quick-release bracket 42 relative to the fixed bracket 41 can be reduced; when the height of the material 70 is high, the rotation angle of the quick-release bracket 42 relative to the fixed bracket 41 can be increased, so that the blocking mechanism can be positioned on the surface of the material 70 in the blocking state.

[0092] Combination Figures 4 to 6 In some embodiments, the packaging production line 100 further includes a second monitoring mechanism 50, which is configured to monitor the position of the material 70. The first monitoring mechanism 20, the second monitoring mechanism 50 and the control mechanism transmit signals. The control mechanism is also configured to control the second monitoring mechanism 50 according to the material state, so that the conveying mechanism 10 drives the material 70 to be opposite to the blocking mechanism, and controls the blocking mechanism to drive the material 70 to a predetermined position, so as to ensure that the blocking mechanism accurately positions and blocks the material 70, and improves the stability of the blocking mechanism in blocking the material 70.

[0093] For example, the conveying mechanism 10 moves the material 70. When the material 70 moves into the monitoring area of ​​the first monitoring mechanism 20, and the first monitoring mechanism 20 detects that the material 70 on the conveying mechanism 10 is in a defective state, the conveying mechanism 10 continues to move the defective material 70. When the second monitoring mechanism 50 detects that the defective material 70 is opposite to the blocking mechanism in the front-back direction, the second monitoring mechanism 50 transmits an electrical signal to the control mechanism. The control mechanism controls the conveying mechanism 10 to stop running, and at the same time controls the blocking mechanism to push the defective material 70 to the designated position. This enables the blocking mechanism to block and locate the defective material 70, making it easier for staff to promptly detect and handle the defective material 70, and preventing the defective material 70 from continuing to flow into the packaging production line 100.

[0094] Compared to manually controlling the start and stop of the conveyor mechanism 10, when problems such as material 70 collisions or accumulation occur on the conveyor mechanism 10, a first monitoring mechanism 20 and a second monitoring mechanism 50 are set up. The first monitoring mechanism 20 and the second monitoring mechanism 50 can send feedback electrical signals to the control mechanism, which can then control the conveyor mechanism 10 to stop operating. At the same time, the blocking mechanism can push the material 70 in a defective state to a designated position to further block the subsequent movement of material 70, thus timely blocking the flow of material 70 and preventing further accumulation and collisions. After the staff has dealt with the problematic area on the conveyor mechanism 10, the staff can manually control the conveyor mechanism 10 to restart, and the conveyor mechanism 10 can resume moving the material 70. This improves the stability and reliability of the material 70 transport on the conveyor mechanism 10, avoids damage to the material 70 caused by collisions and accumulation, and improves the production efficiency of the packaging production line 100.

[0095] In some embodiments, the second monitoring mechanism 50 includes an image recognition and processing module, a limit switch, and / or a micro switch. Specifically, the second monitoring mechanism 50 may include an image recognition and processing module; or, the second monitoring mechanism 50 may include a limit switch; or, the second monitoring mechanism 50 may include a micro switch; or, the second monitoring mechanism 50 may include both an image recognition and processing module and a limit switch; or, the second monitoring mechanism 50 may include both a limit switch and a micro switch, facilitating the second monitoring mechanism 50 to monitor the position of the material 70 and transmit control signals to the control mechanism, thereby controlling the blocking mechanism to switch between blocking and releasing states.

[0096] Optionally, combined Figure 4 and Figure 5 The second monitoring unit 50 may also include an image recognition and processing module. Image processing and recognition technology refers to the technology of converting an image of the external world into computer-accessible data and then recognizing it. The image recognition and processing module learns and forms various image features required for recognition, and correctly distinguishes the category of the image to be recognized based on these features. Specifically, the image recognition and processing module can determine whether the defective material 70 is opposite the blocking mechanism in the front-back direction through image acquisition, image preprocessing, feature extraction, and image recognition processes, and transmit electrical signals to the control mechanism so that the control mechanism can control whether the blocking mechanism blocks the material 70 and whether the conveying mechanism 10 stops operating.

[0097] For example, the first monitoring agency 20 can monitor the material status of the conveying mechanism 10 and determine whether the material status is good or bad. If the material is in a good condition, the blocking mechanism switches to the release state, and the conveying mechanism 10 continues to transport the material 70. If the material is in a defective state, the first monitoring mechanism 20 sends a signal back to the control mechanism to ensure that the power source 36 is turned on and provides power to the blocking mechanism. The second monitoring mechanism 50 can be located on the side rail 311. When the second monitoring mechanism 50 detects that the defective material 70 is opposite the blocking mechanism in the front-back direction, the second monitoring mechanism 50 sends a signal back to the control mechanism. The control mechanism drives the blocking mechanism to switch to the blocking state. The blocking mechanism can accurately locate and block the defective material 70. At the same time, the control mechanism can control the conveying mechanism 10 to stop running, so that the blocking mechanism can block and intercept the defective material 70 in time and prevent the material 70 upstream of the conveying mechanism 10 from continuing to move in the conveying direction. This makes it easier for staff to discover and deal with the defective material 70 in time, reduce the input of defective material 70 into the packaging production line 100, and improve the stability and reliability of the packaging production line 100.

[0098] Optionally, combined Figure 6 The second monitoring mechanism 50 may also include a limit switch, a type of position switch (also known as a limit switch), which is a commonly used low-current control electrical appliance. It utilizes the collision of moving parts of the production machinery to actuate its contacts, thereby connecting or disconnecting the control circuit to achieve a certain control purpose. These switches are used to limit the position or travel of mechanical movement, causing the moving machinery to automatically stop, reverse, change speed, or automatically reciprocate at a certain position or travel. The conveying mechanism 10 may include a chain and a chain support. The limit switch may be located on the inner wall of the chain support and opposite the blocking mechanism in the front-back direction. At least a portion of the limit switch's contacts are located on the conveying trajectory of the material 70; that is, at least a portion of the limit switch's contacts extend above the chain. When the material 70 collides with the limit switch, the limit switch connects the circuit.

[0099] For example, if the first monitoring mechanism 20 detects that the material in the conveying mechanism 10 is in a defective state, and the material 70 collides with the limit switch, causing the limit switch to conduct, the limit switch can transmit an electrical signal to the control mechanism. The control mechanism can then control the blocking mechanism to push the defective material 70 to a predetermined position, achieving precise positioning and blocking of the defective material 70 for timely handling. After the material 70 leaves the limit switch, a reset spring can be provided inside the limit switch to return it to the open state.

[0100] Optionally, combined Figure 6The second monitoring mechanism 50 may also include a micro switch. External mechanical force is applied to the actuating spring through a transmission element (button, lever, roller, etc.). When the actuating spring is displaced to a critical point, an instantaneous action is generated, causing the moving contact at the end of the actuating spring to quickly connect or disconnect with the fixed contact. When the force on the transmission element is removed, the actuating spring generates a reverse action force. When the reverse stroke of the transmission element reaches the actuating critical point of the actuating spring, the reverse action is completed instantaneously. The micro switch has a small contact spacing, short stroke, low actuation force, and rapid switching. The action speed of its moving contact is independent of the action speed of the transmission element. The conveying mechanism 10 may include a chain and a chain support. The micro switch may be located on the inner wall of the chain support and is opposite to the blocking mechanism in the front-back direction. At least part of the actuating spring of the micro switch is located on the conveying trajectory of the material 70. That is, at least part of the actuating spring of the micro switch extends above the chain. When the material 70 collides with the micro switch, the micro switch conducts the circuit.

[0101] For example, when the first monitoring mechanism 20 detects that the material in the conveying mechanism 10 is in a defective state, and the material 70 collides with the micro switch, causing the micro switch to conduct, the micro switch can transmit an electrical signal to the control mechanism. The control mechanism can then control the blocking mechanism to push the defective material 70 to a predetermined position, achieving precise positioning and blocking of the defective material 70 for timely handling. When the material 70 leaves the micro switch, the actuating spring of the micro switch returns to the open state.

[0102] Optionally, the packaging production line 100 of this utility model embodiment also includes a display screen. The display screen can display the status of the first monitoring mechanism 20, the second monitoring mechanism 50 and the conveying mechanism 10, such as the position of multiple materials 70, the conveying speed of the conveying mechanism 10, etc., and can also display the movement of the blocking mechanism, such as the movement and position of the piston rod 332 of the cylinder 331 in the drive unit 33. The production status of the packaging production line 100 can be observed through the visual interface, which is convenient for timely detection and handling of the situation in the packaging production line 100.

[0103] The packaging production line 100 of this utility model embodiment has at least the following technical effects: Through the first monitoring mechanism 20 and the control mechanism, precise control of the blocking mechanism's movement can be achieved, ensuring a higher level of accuracy and smaller error in the blocking material's position; the optimized structural design results in less deformation and more stable performance of the blocking mechanism during long-term use, reducing the problem of decreased precision due to equipment aging; the parameters of the control mechanism can be adjusted to quickly adapt to changes in speed, product specifications, and working environment of different production lines without the need for complex mechanical adjustments; high-quality materials and the buffer structure 34 reduce wear and damage to parts, lowering maintenance frequency and costs; the control mechanism and display screen can provide early warnings of potential faults, facilitating timely maintenance and preventing major malfunctions, thereby extending the service life of the blocking mechanism; the control mechanism can adjust the action force and speed of the blocking mechanism according to actual needs, avoiding unnecessary energy waste.
