Description

Technical Field

[0001] This application relates to the field of filling technology, and in particular to a container conveying device for a filling production line. Background Technology

[0002] Filling is the process of injecting contents into a container through a pipe or nozzle. The contents can be liquid, semi-solid, or powdered. Containers can be plastic, glass, or metal bottles. Filling is widely used in the beverage, food, cosmetics, and pharmaceutical industries, and can be tailored to the characteristics of the product and packaging requirements to meet the needs of different industries and consumers.

[0003] In a bottling line, the transfer of empty containers relies on conveyors. The conveyor directions of two adjacent processes may be perpendicular. As rows of empty containers move from one conveyor to another, the inertia of the multiple rows helps the first few containers smoothly and synchronously pass through the junction of the two conveyors. When the last row or the last two rows of empty containers attempt to pass through the junction, they lack support, making it difficult for them to pass smoothly and increasing the risk of tipping over. This is especially true when the empty containers have a high center of gravity and are relatively light; they are even more prone to tipping over at the junction of the two conveyors.

[0004] The existing technical solutions described above have the following drawbacks: when the last row or the last two rows of empty containers are about to pass through the junction of the two conveyors, the lack of support from the multiple rows of empty containers makes it difficult for them to pass smoothly, and they are prone to tipping over. This is especially true when the empty containers have a high center of gravity and are relatively light, making them even more susceptible to tipping over at the junction of the two conveyors, severely restricting production efficiency. Summary of the Invention

[0005] To improve production efficiency, this application provides a container conveying device for a filling production line.

[0006] This application provides a container conveying device for a filling production line, which adopts the following technical solution: A container conveying device for a filling production line, comprising: The first conveying mechanism is used to convey multiple empty containers arranged in multiple rows and columns; The second conveying mechanism is located on one side of the first conveying mechanism, and its conveying direction is perpendicular to that of the first conveying mechanism. It is used to convey multiple empty containers arranged in a single row. The material feeding mechanism is located on the same side of the first conveying mechanism and the second conveying mechanism, and is used to feed each row of empty containers on the first conveying mechanism to the second conveying mechanism.

[0007] By adopting the above technical solution, the material feeding mechanism applies a pushing force to one end of the same row of empty containers, causing the rows of empty containers to be transferred sequentially from the first conveyor mechanism to the second conveyor mechanism. Since the rows of empty containers no longer pass through the connection point synchronously, and each empty container in each row has a support object, it ensures that each empty container in each row can smoothly pass through the connection point of the two conveyor mechanisms, and that tipping is unlikely during passage. Even if the empty containers have a high center of gravity and are relatively light, tipping is unlikely when passing through the connection point of the two conveyor mechanisms, ensuring production continuity and improving production efficiency.

[0008] This application further specifies that the material feeding mechanism includes: The box body is perpendicular to the conveying direction of the first conveying mechanism in its length direction, and the side closest to the first conveying mechanism is an open structure; Driven sprocket, with its axis set vertically, is rotatably mounted at one end of the housing; The drive sprocket has a vertically aligned axis and is rotatably mounted on the other end of the housing. The drive chain is wound around the driving sprocket and the driven sprocket; The gearbox is fixed to the top of the housing, and the output shaft is fixedly connected to the top of the drive sprocket. The drive motor is fixed to the top of the housing, and its output shaft is fixedly connected to the input shaft of the gearbox. A toggle plate, installed on the outside of the drive chain, moves with the drive chain and is used to move each row of empty containers on the first conveyor mechanism to the second conveyor mechanism; Multiple limiting components are installed in the middle of the housing and abut against the inner wall of the transmission chain. The tension adjustment component is installed at the top of the housing and is rotatably connected to the driven sprocket. It can drive the driven sprocket to move toward or away from the driving sprocket to adjust the tension of the drive chain.

[0009] By adopting the above technical solution, the drive motor, through the reduction gearbox, can drive the active sprocket to rotate, thereby driving the transmission chain and driven sprocket to rotate, and thus driving the actuating plate to move along the length of the box. During the movement of the actuating plate, a thrust is applied to one end of the empty containers in the same row, pushing the rows of empty containers to be transferred one by one from the first conveying mechanism to the second conveying mechanism. The chain drive method has high transmission efficiency and a long transmission distance, enabling the rows of empty containers to quickly complete the position transfer, ensuring production cycle time. Multiple limiting components effectively prevent deformation of the transmission chain, ensuring transmission efficiency and effect, and thus ensuring material feeding efficiency and effect. By adjusting the tension of the transmission chain, transmission efficiency and effect can be guaranteed, thus ensuring material feeding efficiency and effect.

[0010] This application is further configured such that: there are two actuating plates, which are evenly installed on the outer side of the transmission chain along the circumference of the transmission chain, and both move with the transmission chain, so as to alternately actuate a single row of empty containers.

[0011] By adopting the above technical solution, the production cycle time is further improved compared to a single toggle plate.

[0012] This application further specifies that: a feeding section is provided at the end of the second conveying mechanism near the first conveying mechanism; Also includes: An interception mechanism is installed at the end of the feeding section away from the first conveying mechanism to intercept empty containers.

[0013] By adopting the above technical solution, the interception mechanism intercepts the empty containers on the feeding section, and the feeding cycle is appropriately controlled to avoid too many empty containers on the second conveying mechanism, thereby avoiding the deformation caused by mutual squeezing between empty containers.

[0014] This application further specifies that the interception mechanism includes: The first support is fixed at the end of the feeding section away from the first conveying mechanism; An intercepting cylinder is mounted on the first support base; The interceptor plate is fixedly connected to the output end of the interceptor cylinder on one side; the interceptor cylinder drives the interceptor plate to move along the width of the feeding section to intercept empty containers.

[0015] This application further includes: The first blocking mechanism consists of two parts, which are respectively installed on opposite sides of the top of the feeding section; There are two second blocking mechanisms, which are respectively installed on opposite sides of the top of the first conveying mechanism; The third blocking mechanism is installed on one side of the top of the middle part of the second conveying mechanism.

[0016] By adopting the above technical solution, the two first blocking mechanisms not only restrict the movement direction of the empty container above the feeding section, but also prevent the empty container above the feeding section from tipping over. The two second blocking mechanisms not only restrict the movement direction of the empty container above the first conveying mechanism, but also prevent the empty container above the first conveying mechanism from tipping over. The third blocking mechanism not only restricts the movement direction of the empty container above the second conveying mechanism, but also prevents the empty container above the second conveying mechanism from tipping over.

[0017] This application further specifies that each first blocking mechanism includes: The second support base consists of two units, which are respectively installed on the top of opposite ends of the feeding section in a way that allows them to move up and down. There are two support cylinders, both with vertical axes, which are installed on the two second support seats in a one-to-one correspondence, and can move along the width direction of the feeding section. There are two support rods, both with their axes set horizontally. They are installed on the support cylinders one-to-one and can move along the width of the feeding section. A blocking bar is set above the feeding section, with its length direction parallel to that of the feeding section, and a clamping protrusion is formed on one side. There are two clamping blocks, which are fixedly connected to one end of each of the two support rods, respectively clamping the opposite ends of the clamped protrusion; The structure of each second blocking mechanism is the same as that of each first blocking mechanism; the structure of each third blocking mechanism is the same as that of each first blocking mechanism.

[0018] By adopting the above technical solution, based on the height of the empty container, the two second support seats can be moved up and down, thereby driving the two support cylinders, two support rods, two clamping blocks, and blocking rods to move up and down, thus adjusting the height of the blocking rods in the vertical direction. Based on the length of the empty container, the two support cylinders can be moved along the width direction of the feeding section, thereby driving the two support rods, two clamping blocks, and blocking rods to move along the width direction of the feeding section, thus roughly adjusting the distance between the blocking rods of the two first blocking mechanisms. Based on the length of the empty container, the two support rods can be moved along the width direction of the feeding section, thereby driving the two clamping blocks and blocking rods to move along the width direction of the feeding section, thus precisely adjusting the distance between the blocking rods of the two first blocking mechanisms. This improves the versatility of each first blocking mechanism. At the same time, it ensures guiding and anti-tipping effects.

[0019] This application further includes: The motion inertia resistance mechanism is installed between the blocking rods of the two first blocking mechanisms to resist the motion inertia of each empty container as it moves from the first conveying mechanism to the feeding section.

[0020] By adopting the above technical solution, the tipping of empty containers in the feeding section can be avoided.

[0021] This application further specifies that the motion inertia resistance mechanism includes: There are two guide plates, which are fixedly connected to the blocking rods of the two first blocking mechanisms on opposite sides, and closed annular grooves are formed on adjacent sides respectively. The interceptor bar is slidably installed in the corresponding grooves at its two ends; There are two fixing blocks, which are respectively installed on the opposite sides of the two guide plates; There are two elastic components; one end of one elastic component is fixedly connected to one of the fixed blocks, and the other end is fixedly connected to one end of the interceptor bar; one end of the other elastic component is fixedly connected to another fixed block, and the other end is fixedly connected to the other end of the interceptor bar.

[0022] By adopting the above technical solution, when rows of empty containers move from the first conveyor mechanism to the second conveyor mechanism, the outer wall of the leftmost empty container abuts against the outer wall of the blocking rod, causing the blocking rod to slide from right to left along the chute. During this process, the length of the two elastic elements gradually increases, applying a force to the rows of empty containers through the blocking rod. The direction of this force is opposite to the direction of movement of the empty containers, which can resist the inertia of the row of empty containers to a certain extent, preventing the empty containers from tipping over and ensuring the production cycle. When the blocking rod moves to the leftmost side of the chute, the pushing force of the row of empty containers on the blocking rod causes the blocking rod to rise along the chute. Then, the force of the two elastic elements restoring their deformation drives the blocking rod to slide from left to right along the chute to reset. This process is repeated to resist the inertia of each row of empty containers moving from the first conveyor mechanism to the feeding section.

[0023] This application further specifies that each elastic element includes multiple expansion joints connected in sequence; Each expansion joint includes: The sleeve has a connecting block on one side and an outlet on the other side; The reel is rotatably mounted inside the sleeve; Coil springs are used to connect the spool and the sleeve; An elastic rope, one end of which is fixedly connected to a connecting block; A rigid rope, with one end wound around a reel.

[0024] By adopting the above technical solution, during the lengthening process of each expansion joint, the elastic rope deforms first, avoiding impact damage caused by direct force on the rigid components. When the external force exceeds the buffer range of the elastic rope, the reel gradually releases the rigid rope, causing the coil spring to twist. The rigidity of the coil spring provides continuous and stable tension, preventing the elastic rope from breaking due to overstretching. During the shortening process of each expansion joint, the coil spring recovers its deformation, driving the reel to rotate and gradually wind up the rigid rope, providing active restoring force. The elastic rope spontaneously recovers its deformation, helping to eliminate the contraction gap and making the contraction process smoother. Overall, it effectively balances flexibility and load-bearing capacity, allowing the elastic component to deform flexibly while bearing load stably, achieving precise reset, and is suitable for progressive expansion scenarios and bidirectional force control scenarios.

[0025] In summary, the beneficial technical effects of this application are as follows: 1. The material feeding mechanism applies a pushing force to one end of the row of empty containers, causing them to be transferred sequentially from the first conveyor to the second conveyor. Because the rows of empty containers no longer pass through the connection point synchronously, and each empty container in each row has a support object, it ensures that each empty container in each row can smoothly pass through the connection point of the two conveyor mechanisms, and that tipping is unlikely during passage. Even if the empty containers have a high center of gravity and are relatively light, tipping is unlikely when passing through the connection point of the two conveyor mechanisms, ensuring production continuity and improving production efficiency.

[0026] 2. The drive motor, through a reduction gearbox, rotates the drive sprocket, which in turn drives the transmission chain and driven sprocket, thereby moving the actuating plate along the length of the container. During the movement of the actuating plate, a thrust is applied to one end of the row of empty containers, pushing the rows of empty containers sequentially from the first conveyor mechanism to the second conveyor mechanism. The chain drive method offers high transmission efficiency and a long transmission distance, enabling the rows of empty containers to quickly complete their position transfer, ensuring production cycle time. Multiple limiting components effectively prevent deformation of the transmission chain, ensuring transmission efficiency and effect, and thus ensuring material feeding efficiency and effect. By adjusting the tension of the transmission chain, transmission efficiency and effect can be maintained, further ensuring material feeding efficiency and effect.

[0027] 3. Use an interception mechanism to intercept empty containers on the feeding section, and appropriately control the feeding cycle to avoid too many empty containers on the second conveying mechanism, thereby preventing the empty containers from squeezing and deforming each other.

[0028] 4. The two first blocking mechanisms not only restrict the movement direction of the empty container above the feeding section, but also prevent the empty container above the feeding section from tipping over. The two second blocking mechanisms not only restrict the movement direction of the empty container above the first conveying mechanism, but also prevent the empty container above the first conveying mechanism from tipping over. The third blocking mechanism not only restricts the movement direction of the empty container above the second conveying mechanism, but also prevents the empty container above the second conveying mechanism from tipping over.

[0029] 5. As the rows of empty containers move from the first conveyor mechanism to the second conveyor mechanism, the outer wall of the leftmost empty container abuts against the outer wall of the blocking bar, causing the blocking bar to slide from right to left along the chute. During this process, the length of the two elastic elements gradually increases, applying a force to the rows of empty containers through the blocking bar. The direction of this force is opposite to the direction of movement of the empty containers, which can resist the inertia of the rows of empty containers to a certain extent, preventing the empty containers from tipping over and ensuring the production cycle. When the blocking bar moves to the leftmost side of the chute, the pushing force of the rows of empty containers on the blocking bar causes the blocking bar to rise along the chute. Then, the force of the two elastic elements restoring their deformation drives the blocking bar to slide from left to right along the chute to reset. This process repeats, resisting the inertia of each row of empty containers moving from the first conveyor mechanism to the feeding section.

[0030] 6. During the lengthening process of each expansion joint, the elastic rope deforms first, preventing direct impact damage to the rigid components. When the external force exceeds the buffer range of the elastic rope, the reel gradually releases the rigid rope, causing the coil spring to twist. The coil spring's rigidity and stored energy provide continuous and stable tension, preventing the elastic rope from breaking due to overstretching. During the shortening process of each expansion joint, the coil spring recovers its deformation, driving the reel to rotate and gradually wind up the rigid rope, providing active restoring force. The elastic rope spontaneously recovers its deformation, helping to eliminate contraction gaps and making the contraction process smoother. Overall, it effectively balances flexibility and load-bearing capacity, allowing the elastic component to deform flexibly while bearing load stably, achieving precise restoring. It is suitable for progressive expansion scenarios and bidirectional force control scenarios. Attached Figure Description

[0033] It should be noted that the empty container refers to the container before filling. After filling is completed, subsequent processes such as labeling, boxing, and coding are carried out.

[0034] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0035] Reference Figure 1 This application discloses a container conveying device for a filling production line, including a first conveying mechanism 110, a second conveying mechanism 120, and a feeding mechanism 130. The first conveying mechanism 110 conveys multiple empty containers arranged in multiple rows and columns. The second conveying mechanism 120 is disposed on one side of the first conveying mechanism 110, with its conveying direction perpendicular to that of the first conveying mechanism 110, and is used to convey multiple empty containers arranged in a single row. The feeding mechanism 130 is disposed on the common side of the first conveying mechanism 110 and the second conveying mechanism 120, and is used to feed each row of empty containers from the first conveying mechanism 110 onto the second conveying mechanism 120. Figure 1 The direction of the arrow indicates the flow direction of the empty containers. Compared to existing container conveying devices, a material-pushing mechanism 130 is added. The material-pushing mechanism 130 applies a pushing force to one end of the same row of empty containers, causing the rows of empty containers to be transferred sequentially from the first conveying mechanism 110 to the second conveying mechanism 120. Since the rows of empty containers no longer pass through the connection point synchronously, and each empty container in each row has a support object, it ensures that each empty container in each row can smoothly pass through the connection point of the two conveying mechanisms, and it is not easy for it to tip over during passage. Even if the empty containers have a high center of gravity and are relatively light, they are not easy to tip over when passing through the connection point of the two conveying mechanisms, ensuring the continuity of production and improving production efficiency.

[0036] Preferably, the first conveying mechanism 110 is a belt conveyor, the structure and working principle of which are existing technologies and will not be described in detail here.

[0037] Preferably, the second conveying mechanism 120 is a chain plate conveyor, the structure and working principle of which are existing technologies and will not be described in detail here.

[0038] Reference Figure 2 and Figure 3In one embodiment, the feeding mechanism 130 includes a housing 131, a driven sprocket 132, a driving sprocket 133, a transmission chain 134, a reduction gearbox 135, a drive motor 136, a shifting plate 137, multiple limiting components 138, and a tension adjusting component 139. The length direction of the housing 131 is perpendicular to the conveying direction of the first conveying mechanism 110, and the side closest to the first conveying mechanism 110 is open. The housing 131 isolates the external and internal transmission components, preventing external interference with the normal operation of the transmission components and extending their service life. The driven sprocket 132 has a vertically oriented axis and is rotatably mounted at one end inside the housing 131. The driving sprocket has a vertically oriented axis and is rotatably mounted at the other end inside the housing 131. The transmission chain 134 is wound around the driving sprocket 133 and the driven sprocket 132. The gearbox 135 is fixed to the top of the housing 131, and its output shaft is fixedly connected to the top of the drive sprocket 133, which increases the output torque and reduces the output speed. The drive motor 136 is fixed to the top of the housing 131, and its output shaft is fixedly connected to the input shaft of the gearbox 135. The actuating plate 137 is installed on the outside of the transmission chain 134 and moves with the transmission chain 134 to move each row of empty containers on the first conveying mechanism 110 to the second conveying mechanism 120. The drive motor 136 can drive the drive sprocket 133 to rotate through the gearbox 135, thereby driving the transmission chain 134 and the driven sprocket 132 to rotate, and thus driving the actuating plate 137 to move along the length of the housing 131. During the movement of the actuating plate 137, a thrust is applied to one end of the empty containers in the same row, pushing the rows of empty containers to be transferred one by one from the first conveying mechanism 110 to the second conveying mechanism 120. The chain drive system offers high transmission efficiency and a long transmission distance, enabling rapid positional transfer of rows of empty containers and ensuring production cycle time. Multiple limiting components 138 are installed in the center of the housing 131, abutting against the inner walls of the drive chain 134 on opposite sides, effectively preventing deformation of the drive chain 134 and ensuring transmission efficiency and effect, thereby guaranteeing material feeding efficiency and effect. A tension adjustment component 139 is installed at the top of the housing 131 and rotatably connected to the driven sprocket 132, driving the driven sprocket 132 to move towards or away from the driving sprocket 133 to adjust the tension of the drive chain 134. By adjusting the tension of the drive chain 134, transmission efficiency and effect are ensured, thus guaranteeing material feeding efficiency and effect.

[0039] Preferably, the drive motor 136 can be a servo motor, which has high motion accuracy. Alternatively, the drive motor 136 can be a stepper motor, which has lower cost.

[0040] Preferably, each limiting component 138 includes a lower connecting plate, an upper connecting plate, and two rotating rods. The lower connecting plate is fixedly connected to the inner bottom surface of the housing 131. The upper connecting plate is fixedly connected to the inner top surface of the housing 131. Both rotating rods are vertically arranged, with their bottom ends rotatably connected to opposite ends of the lower connecting plate, their top ends rotatably connected to opposite ends of the upper connecting plate, and their sidewalls abutting against the inner sides of opposite sides of the transmission chain 134. The rotating rods prevent the transmission chain 134 from deforming. Because each rotating rod can rotate, the resistance to the movement of the transmission chain 134 is reduced, ensuring transmission efficiency and extending the service life of the transmission chain 134.

[0041] Preferably, the tension adjustment assembly 139 includes a fixed base, a fixed rod, and an adjusting bolt. The fixed base is fixed to the top of the housing 131. The fixed rod is vertically arranged, with its bottom end rotatably connected to the driven sprocket 132 and its top end connected to the fixed base via the adjusting bolt. By rotating the adjusting bolt, the fixed rod can be moved, thereby causing the driven sprocket 132 to move toward or away from the driving sprocket 133, thus adjusting the tension of the transmission chain 134.

[0042] Preferably, there are two actuating plates 137, which are evenly installed on the outer side of the transmission chain 134 along its circumference. Both move with the transmission chain and can alternately actuate a single row of empty containers. Compared to a single actuating plate 137, this further improves the production cycle time.

[0043] Reference Figure 4 and Figure 5 In one embodiment, the second conveying mechanism 120 has a feeding section 121 at the end near the first conveying mechanism 110. The container conveying device for the filling production line also includes an intercepting mechanism 140. The intercepting mechanism 140 is installed at the end of the feeding section 121 away from the first conveying mechanism 110 and is used to intercept empty containers. When there are too many empty containers on the second conveying mechanism 120, the mutual squeezing force can easily deform the empty containers. Therefore, by setting up the intercepting mechanism 140, the empty containers on the feeding section 121 are intercepted, the feeding rhythm is appropriately controlled, and too many empty containers are avoided on the second conveying mechanism 120, thereby preventing the empty containers from squeezing and deforming each other. In addition, the intercepting mechanism 140 can resist the inertia of the empty containers on the feeding section 121, preventing the empty containers from tipping over and ensuring the production rhythm.

[0044] Reference Figure 5In one embodiment, the interception mechanism 140 includes a first support base 141, an interception cylinder 142, and an interception plate 143. The first support base 141 is fixed to the end of the feeding section 121 away from the first conveying mechanism 110. The interception cylinder 142 is mounted on the first support base 141. One side of the interception plate 143 is fixedly connected to the output end of the interception cylinder 142. The interception cylinder 142 drives the interception plate 143 to move along the width direction of the feeding section 121 to intercept or release empty containers.

[0045] Reference Figure 1 In one embodiment, the container conveying device for the filling production line further includes two first blocking mechanisms 150, two second blocking mechanisms 160, and a third blocking mechanism 170. The two first blocking mechanisms 150 are respectively installed on opposite sides of the top of the feeding section 121, serving to both restrict the movement direction of the empty containers on the feeding section 121 and prevent the empty containers on the feeding section 121 from tipping over. The two second blocking mechanisms 160 are respectively installed on opposite sides of the top of the first conveying mechanism 110, serving to both restrict the movement direction of the empty containers on the first conveying mechanism 110 and prevent the empty containers on the first conveying mechanism 110 from tipping over. The third blocking mechanism 170 is installed on one side of the top of the middle section of the second conveying mechanism 120, serving to both restrict the movement direction of the empty containers on the second conveying mechanism 120 and prevent the empty containers on the second conveying mechanism 120 from tipping over.

[0046] Reference Figure 4 and Figure 5In one embodiment, each first blocking mechanism 150 includes two second support seats 151, two support cylinders 152, two support rods 153, a blocking rod 154, and two clamping blocks 155. The two second support seats 151 are respectively movably mounted vertically on the tops of opposite ends of the feeding section 121. The axes of the two support cylinders 152 are both vertically arranged and are mounted on the second support seats 151 corresponding to each other, and are respectively movable along the width direction of the feeding section 121. The axes of the two support rods 153 are both horizontally arranged and are mounted on the support cylinders 152 corresponding to each other, and are respectively movable along the width direction of the feeding section 121. The blocking rod 154 is disposed above the feeding section 121, its length direction is parallel to the length direction of the feeding section 121, and a clamping protrusion 1541 is formed on one side. Two clamping blocks 155 are fixedly connected to one end of each of the two support rods 153, respectively clamping the opposite ends of the clamped protrusions 1541. Depending on the height of the empty container, the two second support seats 151 can move up and down, thereby moving the two support cylinders 152, two support rods 153, two clamping blocks 155, and blocking rods 154 up and down to adjust the vertical height of the blocking rods 154. Depending on the length of the empty container, the two support cylinders 152 can move along the width of the feeding section 121, thereby moving the two support rods 153, two clamping blocks 155, and blocking rods 154 along the width of the feeding section 121, thus roughly adjusting the distance between the blocking rods 154 of the two first blocking mechanisms 150. Based on the length of the empty container, the two support rods 153 can move along the width direction of the feeding section 121, thereby driving the two clamping blocks 155 and the blocking rod 154 to move along the width direction of the feeding section 121, and thus precisely adjusting the distance between the blocking rods 154 of the two first blocking mechanisms 150. This improves the versatility of each first blocking mechanism 150. At the same time, it ensures guiding and anti-tipping effects.

[0047] Preferably, each second support 151 has a first adjustment hole and a second adjustment hole. Each second support 151 is connected to the feed section 121 through the first adjustment hole, allowing each second support 151 to move up and down. Each second support 151 is connected to the bottom end of the corresponding support cylinder 152 through the second adjustment hole, allowing the corresponding support cylinder 152 to move along the width direction of the feed section 121.

[0048] Preferably, a through hole is formed at the top of the support cylinder 152. The support rod 153 passes through the through hole. A locking bolt is installed at the top of the support cylinder 152. One end of the locking bolt can press against or disengage from the side wall of the support rod 153 to restrict the movement of the support rod 153 along the width direction of the feed section 121 or to release the restriction on the support rod 153.

[0049] Preferably, the structure of each second blocking mechanism 160 is the same as that of each first blocking mechanism 150. The structure of each third blocking mechanism 170 is the same as that of each first blocking mechanism 150.

[0050] Reference Figure 6 In one embodiment, the container conveying device for the filling production line further includes a motion inertia resistance mechanism 180. The motion inertia resistance mechanism 180 is installed between the blocking rods 154 of the two first blocking mechanisms 150 to resist the motion inertia of each row of empty containers as they move from the first conveying mechanism 110 to the feeding section 121, thereby preventing the empty containers on the feeding section from tipping over.

[0051] Reference Figure 7 , Figure 8 and Figure 9 In one embodiment, the motion inertia resistance mechanism 180 includes two guide plates 181, an intercepting rod 182, two fixing blocks 183, and two elastic members 184. The opposing sides of the two guide plates 181 are respectively fixedly connected to the blocking rods 154 of the two first blocking mechanisms 150, and adjacent sides respectively form closed annular grooves 1811. The opposing ends of the intercepting rods 182 are slidably installed in the corresponding grooves 1811. The two fixing blocks 183 are respectively installed on the opposing sides of the two guide plates 181. One end of one elastic member 184 is fixedly connected to one fixing block 183, and the other end is fixedly connected to one end of the intercepting rod 182. One end of the other elastic member 184 is fixedly connected to the other fixing block 183, and the other end is fixedly connected to the other end of the intercepting rod 182. As rows of empty containers move from the first conveyor mechanism 110 to the second conveyor mechanism 120, the outer wall of the leftmost empty container abuts against the outer wall of the blocking rod 154, causing the intercepting rod 182 to slide from right to left along the chute 1811. During this process, the length of the two elastic elements 184 gradually increases, applying a force to the rows of empty containers through the intercepting rod 182. The direction of this force is opposite to the direction of movement of the empty containers, which can resist the inertia of the row of empty containers to a certain extent, preventing the empty containers from tipping over and ensuring the production cycle. When the intercepting rod 182 moves to the leftmost side of the chute 1811, the pushing force of the row of empty containers on the intercepting rod 182 causes the intercepting rod 182 to rise along the chute 1811. Then, the force of the two elastic elements 184 restoring their deformation causes the intercepting rod 182 to slide from left to right along the chute 1811 to reset. This process repeats itself, which helps to resist the inertia of each row of empty containers as they move from the first conveyor mechanism 110 to the feeding section 121.

[0052] Preferably, the cross-section of the interceptor 182 is a parallelogram. The chute 1811 is a parallelogram groove, so that the interceptor 182 can climb along the left side of the chute 1811 using the thrust of the empty container, without the need for an additional climbing drive source.

[0053] Reference Figure 9 and Figure 10 Each elastic element 184 includes a plurality of telescopic joints 1841 connected in sequence. Each telescopic joint 1841 includes a sleeve 18411, a reel 18412, a coil spring 18413, an elastic rope 18414, and a rigid rope 18415. A connecting block 184111 is formed on one side of the sleeve 18411, and an outlet 184112 is formed on the other side. The reel 18412 is rotatably mounted inside the sleeve 18411. The coil spring 18413 is disposed inside the sleeve 18411 for connecting the reel 18412 and the sleeve 18411. One end of the elastic rope 18414 is fixedly connected to the connecting block 184111, and the other end is connected to the rigid rope 18415 / fixed block 183 of another telescopic joint 1841. One end of the rigid rope 18415 is wound around the reel 18412, and the other end passes through the outlet 184112 and connects to the elastic rope 18414 / interception bar 182 of another telescopic joint 1841. During the lengthening process of each telescopic joint 1841, the elastic rope 18414 deforms first, preventing direct impact damage to the rigid component. When the external force exceeds the buffer range of the elastic rope 18414, the reel 18412 gradually releases the rigid rope 18415, causing the coil spring 18413 to twist. The rigidity and stored energy of the coil spring 18413 provide a continuous and stable tension, preventing the elastic rope 18414 from breaking due to overstretching. During the shortening process of each telescopic joint 1841, the coil spring 18413 recovers its deformation, driving the reel 18412 to rotate, gradually winding up the rigid rope 18415, providing an active restoring force. The elastic rope 18414 spontaneously recovers its deformation, helping to eliminate contraction gaps and making the contraction process smoother. Overall, it effectively balances flexibility and load-bearing capacity, enabling the elastic element 184 to deform flexibly while bearing load stably, achieving precise reset, and is suitable for progressive expansion and contraction scenarios as well as bidirectional force control scenarios.

[0054] The implementation principle of this embodiment is as follows: By setting up a material feeding mechanism 130, the material feeding mechanism 130 applies a pushing force to one end of the row of empty containers, causing the rows of empty containers to be transferred one by one from the first conveying mechanism 110 to the second conveying mechanism 120 in sequence. Since the rows of empty containers no longer pass through the connection point synchronously, and each empty container in each row has a support object, it is ensured that each empty container in each row can smoothly pass through the connection point of the two conveying mechanisms, and it is not easy for it to tip over during passage. Even if the empty containers have a high center of gravity and are relatively light, they are not easy to tip over when passing through the connection point of the two conveying mechanisms, ensuring the continuity of production and improving production efficiency.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
