Description

Technical Field

[0001] This utility model relates to the field of automated tooling production equipment technology, and in particular to a production line for installing inner pads on bottled products. Background Technology

[0002] In recent years, more and more high-end daily chemical products have adopted colorful bottle packaging, which greatly enhances the packaging grade of the products and makes them more popular.

[0003] In the production process of bottled products, some cosmetics such as loose powder, pressed powder or face mask need to go through a series of operations such as filling, adding inner pads, and screwing on caps. In the first operation, for the inner pad operation, after the inner pad is placed into the bottle, it needs to be pressed and fixed between the inner pad and the bottle body so that the inner pad is embedded in the bottle body. After the inner pad is added, the next operation process can be carried out.

[0004] In this process, the traditional method of pressing the inner pad is achieved by driving the pressing plate with a lifting cylinder. However, this pressing method results in a lot of gas remaining in the bottle. Moreover, if the product in the bottle is squeezed out from the inner pad side under the action of gas, the quality of the product in the bottle will be reduced and will not meet the actual production requirements.

[0005] Therefore, in order to realize the installation of inner pads in bottled products, it is urgent to design a growth line that can automatically install and press the inner pads. Utility Model Content

[0006] Purpose of the utility model: To address the problems existing in the prior art, this utility model provides a production line for installing inner pads in bottled products. After the inner pads are fed, a designed transverse pressing belt pulley machine is used to press the inner pads. The mold conveying mechanism drives the bottle and the inner pads to move towards the transverse pressing belt pulley machine. Under the action of the transverse pressing belt pulley machine, the inner pads are pressed from one side to the other. During this process, some of the gas in the bottle can be gradually discharged to prevent the bottle product from splashing out due to the up and down pressing.

[0007] Technical solution: This utility model provides a production line for installing inner pads in bottled products, including a workbench, on which a mold conveying mechanism is provided, and pairs of clamping parts are arranged at intervals on the mold conveying mechanism; an inner pad feeding mechanism and an inner pad pressing mechanism are arranged sequentially on one side of the workbench of the mold conveying mechanism. The inner pad feeding mechanism includes an inner pad conveying line, an inner pad suction cup, and a first driving component that drives the inner pad suction cup to move up and down and back and forth. The inner pad suction cup picks up the inner pad from the inner pad conveying line and puts it into the bottle body on the mold conveying mechanism. The inner pad pressing mechanism includes a pressing belt pulley machine arranged along the conveying direction of the mold conveying mechanism. The pressing belt pulley machine is located directly above the mold conveying mechanism and is in contact with the bottle surface on the mold conveying mechanism.

[0008] Furthermore, the inner pad transmission line includes a conveyor belt pulley, on which at least a pair of side baffles are provided, and an upper baffle is connected above the pair of side baffles via a bracket, and the inner pad moves on the conveyor belt pulley between the pair of side baffles and the upper baffle.

[0009] Furthermore, a first threaded rod is vertically rotatably connected to the side stop bar near the side of the conveyor belt pulley. The first threaded rod is threadedly connected to the support set on the conveyor belt pulley. The bracket is provided with a strip groove. The upper stop bar is fixedly connected by a stop bar connecting rod that passes through the strip groove. The stop bar connecting rod is fixed to the bracket by a clamping block.

[0010] Furthermore, a first temporary inner pad receiving platform with a height matching the inner pad transmission line is provided on the worktable near the mold conveying mechanism. A pair of limiting plates are provided on the first temporary inner pad receiving platform.

The surface of the second temporary inner pad receiving platform is recessed inward to form a circular groove, and an inner pad transfer notch is provided on the side facing the first temporary inner pad receiving platform. The width of the inner pad transfer notch matches the spacing between the pair of limiting plates.

[0011] Furthermore, the second inner pad temporary receiving platform is also slidably mounted on a first slide rail fixed to the workbench. The first slide rail is arranged along the direction of the mold conveying mechanism, and the second inner pad temporary receiving platform is driven to slide on the first slide rail by a first cylinder.

[0012] Furthermore, the first driving component includes a first electric slide rail and a second electric slide rail. The first electric slide rail is vertically arranged, and its sliding end is connected to an inner pad suction cup through a suction cup connecting plate. The second electric slide rail is arranged in a direction perpendicular to the mold conveying mechanism, and the first electric slide rail is arranged on the second electric slide rail.

[0013] Furthermore, the pressing belt pulley machine includes a pressing drive motor, an active pressing wheel, a driven pressing wheel, and a pressing belt disposed between the active pressing wheel and the driven pressing wheel. The pressing drive motor is driven and connected to the active pressing wheel. The inner surface of the pressing belt that contacts the mold conveying mechanism is provided with a plurality of pressing wheels, and the two ends of the pressing wheels are rotatably connected to the pressing connecting plate through bearings.

[0014] Furthermore, each of the left and right ends of the pressing pulley machine is respectively mounted on a height fine-tuning component. The height fine-tuning component includes a height connecting plate. A pair of pressing connecting plates are fixed together by a pressing fixing plate. A first connecting seat is provided on the upper surface of the pressing fixing plate, and a second connecting seat is provided on the lower surface of the height connecting plate. The first connecting seat and the second connecting seat are rotatably connected by a rotating shaft. A second threaded rod is threadedly connected to the height connecting plate, and a first adjusting handwheel is connected to the second threaded rod.

[0015] Furthermore, a limiting clamping mechanism is also provided on the mold conveying mechanism opposite to the inner pad feeding mechanism. The limiting clamping mechanism includes a bidirectional clamping cylinder. The actuating end of the bidirectional clamping cylinder is connected to a clamping head. The actuating direction of the bidirectional clamping cylinder is perpendicular to the conveying direction of the mold conveying mechanism, and a pair of clamping heads are directly opposite the bottle on the mold conveying mechanism.

[0016] Furthermore, an inner pad detection mechanism is also provided on the worktable on one side of the inner pad pressing mechanism. The inner pad detection mechanism includes a first lifting cylinder, which is located directly above the mold conveying mechanism.

[0020] Beneficial effects:

[0021] 1. This utility model utilizes a designed transverse pressing belt conveyor to achieve the pressing operation of the inner pad. The mold conveying mechanism drives the bottle and inner pad to move towards the transverse pressing belt conveyor. Under the action of the transverse pressing belt conveyor, the inner pad is pressed from one side to the other. During this process, some of the gas inside the bottle can be gradually discharged, preventing the product from splashing out of the bottle due to the up-and-down pressing. In addition, when feeding the inner pad, the inner pad is directly transferred into the bottle through the inner pad suction cup, completing the automated feeding process.

[0022] 2. The inner pad transmission line designed in this utility model directly places the inner pad on the conveyor belt pulley to complete the purpose of moving the inner pad towards the mold conveying mechanism. The side baffles play a left and right limiting role, and the upper baffles play an upper limiting role, preventing two inner pads from being stacked together and transmitted forward, ensuring single transmission.

[0023] 3. This utility model has a threaded rod on one side of the side stop bar. The position of the side stop bar can be adjusted by rotating the threaded rod, so as to adapt to the feeding operation of inner pads of different sizes. A strip groove is set on the bracket, so that the position of the stop bar connecting rod can be adjusted in the strip groove, and the height can be adjusted up and down, which can also adapt to inner pads of different heights.

[0024] 4. This utility model provides a first temporary receiving platform for inner pads on one side of the inner pad conveyor line. The inner pads on the conveyor line first enter the first temporary receiving platform and are limited by the limiting plates on both sides, preventing them from moving left or right. When it is necessary to feed the inner pads, the second temporary receiving platform aligns with the first temporary receiving platform, and the inner pads are transferred from the first temporary receiving platform to the circular groove of the second temporary receiving platform. At this time, the inner pad conveyor line continues to convey, but the inner pads cannot move forward due to the obstruction of the second temporary receiving platform. Only after the inner pads in the second temporary receiving platform are transferred out can the inner pads continue to move onto the second temporary receiving platform for the next round of feeding. Furthermore, in the design of this utility model, the second temporary receiving platform for the inner pad can be driven by the first cylinder to be offset from the first temporary receiving platform for the inner pad. When feeding is required, the second temporary receiving platform for the inner pad moves under the action of the first cylinder and docks with the first temporary receiving platform for the inner pad. After the inner pad is transferred, the second temporary receiving platform for the inner pad is driven by the first cylinder to move to one side. At this time, the inner pad transfer notch and the limiting plate are not aligned. The second temporary receiving platform for the inner pad is close to the inner pad suction cup. The inner pad on the first temporary receiving platform is blocked by the edge of the second temporary receiving platform for the inner pad and cannot move forward, thus completing the intermittent feeding process.

[0025] 5. This utility model uses an electric slide rail to move the inner pad suction cup up and down and back and forth, so as to move it closer to the inner pad to pick it up and drive the inner pad to be transferred into the bottle body on the mold conveying mechanism.

[0026] 6. The pressing belt pulley structure designed in this utility model drives the pressing belt to rotate through a pressing drive motor, and a pressing wheel is set inside the belt to achieve balanced pressing of the inner pad. When the mold conveying mechanism moves the bottle body towards the pressing belt pulley, the bottle body gradually enters the pressing area under the pressing belt, which can simultaneously press and partially expel the gas inside the bottle, reducing product splashing.

[0027] 7. This utility model has both sides of the pressing drive motor mounted on the height fine-tuning components. On the one hand, the height of the overall pressing drive motor can be adjusted by the height fine-tuning components to adapt to different bottle heights. On the other hand, the pressing pulley can be tilted by the height fine-tuning components on both sides, so that when the bottle enters the pressing pulley, it can be obliquely squeezed and pressed into the inner pad.

[0028] 8. The purpose of this utility model design is to address the issue that after the mold conveying mechanism transports the bottle to a certain station, other stations on the mold conveying mechanism may require the clamping components to be in a non-clamping state. If the bottle is in a non-clamping state, it may wobble, which could lead to instability during the inner padding process. The limiting clamping mechanism can temporarily clamp the bottle to maintain stability. After the inner padding is completed, the bottle can be released, and the clamping components on the mold conveying mechanism can be used again for clamping.

[0029] 9. The inner pad detection mechanism designed in this utility model uses a first lifting cylinder to drive the lower detection plate downwards, directly facing the bottle body on the mold conveying mechanism. If there is a detection rod inside the bottle, the detection rod will be squeezed upwards after contacting the inner pad, thus compressing the spring. During the upward movement of the detection rod, it is detected by a photoelectric switch, confirming the presence of an inner pad inside the bottle. If there is no inner pad, the detection rod is not subjected to force and will not move upwards to be detected by the photoelectric switch, confirming the absence of an inner pad inside the bottle.

[0030] 10. For bottles without inner pads, which are considered substandard products, this utility model uses a second lifting cylinder to drive a feeding robot to feed the bottle onto the feeding conveyor belt. During the transfer to the feeding conveyor belt, the second cylinder drives the second lifting cylinder to slide on the second slide rail, realizing the movement between the mold conveying mechanism and the feeding conveyor belt.

[0031] 11. After the inner pad is installed inside the bottle, dust and other substances are easily accumulated on the inner pad, requiring further cleaning of the inner pad and the bottle body. To this end, the cleaning connecting rod is raised and lowered by the third lifting cylinder, which in turn raises and lowers the air blowing pipe and cleaning cover below it. The cleaning cover is directly facing the bottle body, the vacuum cleaner is driven to perform the suction operation, and the blower performs the blowing operation to complete the cleaning operation.

[0032] 12. In order to facilitate the adjustment of the height of the blower, the non-conforming product unloading mechanism and the inner pad cleaning mechanism, the present invention can set all three on the height fine adjustment component. The height fine adjustment component is similar in structure to the height fine adjustment component of the pressing belt pulley machine, and the overall height can be adjusted by the threaded rod and the adjusting handwheel.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] See Figure 1 This utility model discloses a production line for installing inner pads in bottled products, including a workbench 1, a mold conveying mechanism 3 on the workbench 1, and pairs of clamping parts 301 spaced apart on the mold conveying mechanism 3; an inner pad feeding mechanism 2 and an inner pad pressing mechanism 4 are sequentially arranged on the workbench 1 on one side of the mold conveying mechanism 3.

[0040] See Figures 2-6 The inner pad feeding mechanism 2 includes an inner pad transmission line 201, an inner pad suction cup 202, and a first driving component that drives the inner pad suction cup 202 to move up and down and back and forth. The inner pad suction cup 202 picks up the inner pad 9 from the inner pad transmission line 201 and puts it into the bottle body 8 on the mold conveying mechanism 3.

[0041] The inner pad conveyor line 201 includes a conveyor belt conveyor 2011, which has at least one pair of side baffles 2012. In this embodiment, two pairs of side baffles 2012 are provided on the conveyor belt conveyor 2011, forming two inner pad conveying paths. An upper baffle 2014 is connected above the pair of side baffles 2012 via a bracket 2013. The inner pad 9 moves on the conveyor belt conveyor 2011 located between the pair of side baffles 2012 and the upper baffle 2012. The conveyor belt conveyor 2011 is driven by a drive motor to drive the main and driven pulleys, which in turn drive the belt to move. This structure is a conventional belt conveyor and will not be described in further detail here.

[0042] A first threaded rod 2015 is vertically rotatably connected to the side baffle 2012 near the side of the conveyor belt pulley 2011. The first threaded rod 2015 is threadedly connected to the support 2016 set on the conveyor belt pulley 2011. By rotating the first threaded rod 2015, the side baffle 2012 can be moved, and the spacing between the paired side baffles 2012 can be adjusted to adapt to different sizes of inner pads 9. A strip groove 2017 is provided on the bracket 2013. The upper stop bar 2012 is fixedly connected by a stop bar connecting rod 2018 that passes through the strip groove 2017. The stop bar connecting rod 2018 is fixed to the bracket 2013 by a clamping block 2019. During actual adjustment, the clamping block 2019 can be loosened, so that the stop bar connecting rod 2018 can be adjusted in position on the strip groove 2017, and can also be adjusted up and down. After adjustment, the stop bar connecting rod 2018 is limited and fixed by the clamping block 2019 to complete the adjustment. In addition, for the two pairs of side stop bars 2012 disclosed in this embodiment, the two side stop bars 2012 located in the middle of the conveyor belt pulley 2011 can be adjusted in relative position in the strip groove 2017 by tightening a hand bolt. The hand bolt 2020 is connected to the inner side stop bar 2012 through the adjusting plate 2021, thereby adjusting the position of the inner side stop bar 2012.

[0043] To facilitate the transfer of the inner pad suction cup 202 to the mold conveying mechanism 3, a first temporary inner pad receiving platform 203 with a height matching the inner pad transmission line 201 is provided on the workbench 1 on the side of the inner pad transmission line 201 near the mold conveying mechanism 3. A pair of limiting plates 204 are provided on the first temporary inner pad receiving platform 203, and the pair of limiting plates 204 can support the inner pad 9. A second temporary inner pad receiving platform 205 is also provided on the workbench 1 between the first temporary inner pad receiving platform 203 and the mold conveying mechanism 3. The surface of the second temporary inner pad receiving platform 205 is recessed inward to form a circular groove 206, and an inner pad transfer notch 207 is provided on the side facing the first temporary inner pad receiving platform 203. The width of the inner pad transfer notch 207 matches the spacing between the pair of limiting plates 204.

[0044] The second inner pad temporary support platform 205 is also slidably mounted on the first slide rail 208 fixed on the workbench 1. The first slide rail 208 is arranged along the direction of the mold conveying mechanism 3. The second inner pad temporary support platform 205 is driven to slide on the first slide rail 208 by the first cylinder 209.

[0045] During the actual feeding process, the inner pad 9 moves on the conveyor belt pulley 2011 to between the limiting plates 204 of the first inner pad temporary receiving platform 203. At this time, the second inner pad temporary receiving platform 205 is located directly below the inner pad suction cup 202, and the inner pad transfer notch 207 of the second inner pad temporary receiving platform 205 is not aligned with the paired limiting plates 204, but is misaligned. The inner pad 9 between the limiting plates 204 cannot be transferred to the second inner pad temporary receiving platform 205 and stays on the first inner pad temporary receiving platform 203 to wait for the next feeding step. After the inner pad 9 on the second inner pad temporary receiving platform 205 is transferred away by the inner pad suction cup 202, the second inner pad temporary receiving platform 205 is pulled back by the first cylinder 209. At this time, the circular groove 206 of the second inner pad temporary receiving platform 205 is directly between the limiting plate 204 of the first inner pad temporary receiving platform 203. Under the action of the conveyor belt pulley 2011, the inner pad 9 moves forward into the circular groove 206 of the second inner pad temporary receiving platform 205, driving the first cylinder 209 to push forward. The second inner pad temporary receiving platform 205 is offset from the limiting plate 204 and moves directly below the inner pad suction cup 202.

[0046] In this embodiment, the first driving component includes a first electric slide rail 210 and a second electric slide rail 211. The first electric slide rail 210 is vertically arranged, and its sliding end is connected to an inner pad suction cup 202 via a suction cup connecting plate 211. The second electric slide rail 211 is arranged in a direction perpendicular to the mold conveying mechanism 3, and the first electric slide rail 210 is disposed on the second electric slide rail 211. The first electric slide rail 210 drives the inner pad suction cup 202 to move up and down, and the second electric slide rail 211 drives the inner pad suction cup 202 to move closer to the mold conveying mechanism 3.

[0047] During actual production line operation, when the clamping component 301 on the mold conveying mechanism 3 clamps the bottle body 8 and transports it to the corresponding position, during the filling process, the clamping component 301 needs to release the bottle body 8 because weighing is required. This results in the entire mold conveying mechanism 3 releasing the bottle body 8, leaving it unclamped and prone to shaking when the inner pad 9 is placed on top. Therefore, a limiting clamping mechanism is also provided on the mold conveying mechanism 3 directly opposite the inner pad feeding mechanism 2. This limiting clamping mechanism includes a bidirectional clamping cylinder 213. The cylinder body of the bidirectional clamping cylinder 213 is fixed to the fixed frame of the mold conveying mechanism 3. The actuating end of the bidirectional clamping cylinder 213 is connected to a clamping head 214. The actuating direction of the bidirectional clamping cylinder 213 is perpendicular to the conveying direction of the mold conveying mechanism 3, and the pair of clamping heads 214 are directly facing the bottle body 8 on the mold conveying mechanism 3. During the inner pad 9 placement process, the clamping component 301 releases the bottle body, and the clamping head 214 is replaced to clamp the bottle body 8.

[0048] See Figure 7 The inner pad pressing mechanism 4 includes a pressing belt pulley 401 arranged along the conveying direction of the mold conveying mechanism 3. The pressing belt pulley 401 is located directly above the mold conveying mechanism 3 and is in contact with the surface of the bottle body 8 on the mold conveying mechanism 3.

[0049] In this embodiment, the pressing belt pulley machine 401 includes a pressing drive motor 4011, an active pressing wheel 4012, a driven pressing wheel 4013, and a pressing belt 4014 disposed between the active pressing wheel 4012 and the driven pressing wheel 4013. The pressing drive motor 4011 is drivenly connected to the active pressing wheel 4012. The pressing drive motor 4011 drives the active pressing wheel 4012 to rotate, which in turn drives the pressing belt 4014 to rotate cyclically between the active pressing wheel 4012 and the driven pressing wheel 4013. A plurality of pressing wheels 4015 are provided on the inner surface of the pressing belt 4014, which is in contact with the mold conveying mechanism 3. The two ends of the pressing wheels 4015 are rotatably connected to the pressing connecting plate 4016 through bearings. In actual operation, the pressing wheels 4015, the active pressing wheel 4012, and the driven pressing wheel 4013 perform a pressing operation on the inner pad 9 located inside the bottle body 8.

[0050] To facilitate height adjustment of the pressing pulley machine 401 and adapt to different bottle heights 8, a height fine-tuning component is respectively installed at both ends of the pressing pulley machine 401. The height fine-tuning component includes a height connecting plate 402, and a pair of pressing connecting plates 4016 are fixed together by a pressing fixing plate 403. A first connecting seat 404 is provided on the upper surface of the pressing fixing plate 403, and a second connecting seat 405 is provided on the lower surface of the height connecting plate. The first connecting seat 404 and the second connecting seat 405 are rotatably connected by a rotating shaft 406. A second threaded rod 407 is threadedly connected to the height connecting plate 402, and a first adjusting handwheel 408 is connected to the second threaded rod 407. When adjusting the height, the first adjusting handwheel 408 drives the second threaded rod 407 to rotate, and the height connecting plate 402 located on the second threaded rod 407 adjusts its height up and down, thereby adjusting the height of the pressing fixing plate 403. This achieves overall height adjustment of the pressing pulley machine 401, and the heights of both sides can be adjusted to different heights to adapt to different needs. To ensure stability during height adjustment, the two sides of the height connecting plate 402 can be fitted onto a guide rod via guide shaft sleeves. The two ends of the guide rod are fixed to the worktable 1 and the upper connecting plate, respectively, to provide guidance.

[0051] After pressing the inner pad 9, it is necessary to further check whether the inner pad 9 is in place or whether the inner pad 9 has been installed. An inner pad detection mechanism 5 is also provided on the workbench 1 on one side of the inner pad pressing mechanism 4. See Figure 9 and Figure 10 The inner pad detection mechanism 5 includes a first lifting cylinder 501, which is located directly above the mold conveying mechanism 3. Its execution end is connected to a detection plate 503 via a detection connecting rod 502. A cylindrical hole 504 is provided in the detection plate 503. A detection rod 505 passes through the detection plate 503 and the cylindrical hole 504 vertically. A limit plate 506 is also provided on the detection rod 505 located in the cylindrical hole 504. A spring 507 is sleeved on the detection rod 505 located in the cylindrical hole 504. The execution end of the first lifting cylinder 501 is also connected to a photoelectric switch 508. During the upward movement of the detection rod 505, it is directly opposite the photoelectric switch 508. During testing, the limiting plate 506 restricts the vertical movement of the detection rod 505 within the detection plate 503. When testing begins, the first lifting cylinder 501 is controlled to move downwards, with the detection rod 505 facing the bottle 8 below. During this downward movement, the detection rod 505 gradually approaches the inner pad 9. Upon contact with the inner pad, the detection rod 505 is subjected to force and moves upwards within the detection plate 503, compressing the spring 507 during this upward movement. The upward movement of the detection rod 505 is detected by the photoelectric switch 508, indicating the presence of the inner pad 9. After testing, the first lifting cylinder 501 rises, the detection rod 505 is no longer subjected to force, and returns to its original position under the action of the spring 507.

[0052] When the inner pad 9 is not detected inside the bottle body 8, the product is considered unqualified. A non-conforming product unloading mechanism 6 is also provided on one side of the inner pad detection mechanism 5. The non-conforming product unloading mechanism 6 includes a second lifting cylinder 601 and a unloading conveyor belt 602 located on one side of the mold conveying mechanism 3. The execution end of the second lifting cylinder 601 is connected to an unloading robot 603. The second lifting cylinder 601 is also mounted on a second driving component, which drives the second lifting cylinder 601 and the unloading robot 603 to move between the mold conveying mechanism 3 and the unloading conveyor belt 602. In this embodiment, the unloading robot 603 is implemented by a bidirectional gripper cylinder, which is equipped with grippers.

[0053] The second driving component includes a second cylinder 604 and a second slide rail 605. The second slide rail 605 is mounted on the unloading connecting plate 606. The second lifting cylinder 601 is slidably mounted on the second slide rail via a cylinder connecting plate 607. The actuating end of the second cylinder 604 is connected to the cylinder connecting plate 607. The second cylinder 604 can be fixed on the frame (not shown in the figure) of the worktable (1). The second cylinder 604 drives the cylinder connecting plate 607 to move back and forth, thereby driving the second lifting cylinder 601 to move back and forth. The second lifting cylinder 601 can then drive the unloading robot 603 below to move up and down, completing the movement control of two degrees of freedom.

[0054] The material conveyor belt 602 in this embodiment can refer to the structure of the inner pad transmission line 2011 described above, and will not be further elaborated here.

[0055] After the inspection is completed, the inner pad 9 needs to be cleaned. See [link / reference]. Figure 11 An inner pad cleaning mechanism 7 is also provided on the workbench 1. The inner pad cleaning mechanism 7 includes a third lifting cylinder 701. The actuating end of the third lifting cylinder 701 is connected to a cleaning connecting rod 702. An air suction pipe 703 is connected to the cleaning connecting rod 702. One end of the air suction pipe 703 is connected to a vacuum cleaner (not shown in the figure), and the other end is connected to a cleaning cover 704. The cleaning cover 703 is directly above the mold conveying mechanism 3. An air blowing pipe 705 is also connected to the cleaning cover 704, and the air blowing pipe 705 is connected to a blower (not shown in the figure). Several air holes 706 are provided through the cleaning cover 703, which can be connected to the air blowing pipe 705 for air blowing.

[0056] To facilitate the adjustment of the height of the inner pad detection mechanism 5, the non-conforming product unloading mechanism 6, and the inner pad cleaning mechanism 7, and to adapt to different bottle bodies 8, in this embodiment, the inner pad cleaning mechanism 7 is respectively set on another height fine-tuning component. The structure of this height fine-tuning component is similar to that of the height fine-tuning component of the pressing belt pulley machine 401. Both are adjusted by adjusting the rotation of the threaded rod through the handwheel to achieve the height adjustment of the overall structure. Further details will not be provided here.

[0057] The mold conveying mechanism 3 used in this embodiment participates in the construction. Figure 12 The mold conveying mechanism 3 includes a first conveyor belt 303 and a second conveyor belt 304. The first conveyor belt 303 is provided with left clamping members at intervals, and the second conveyor belt 304 is provided with right clamping members. The clamping heads of each pair of left clamping members and right clamping members are arranged facing each other.

[0058] In this embodiment, the first conveyor belt conveyor 303 and the second conveyor belt conveyor 304 have the same structure, both including a main drive pulley 305, a driven pulley 306, and a conveyor belt 307 located between the main drive pulley 305 and the driven pulley 306. The main drive pulley 305 is driven by a drive motor 308. The conveyor belts 307 of both are located on the same horizontal line and are driven synchronously by the drive motor 308.

[0059] When the mold conveying mechanism 3 clamps the bottle body 8, the distance between the left and right clamping parts is slightly larger than the diameter of the bottle body 8. During clamping, the first conveyor belt 303 moves a small distance from left to right, and the second conveyor belt 304 moves a small distance from right to left. The left and right clamping parts approach each other, clamping the bottle body 8. After clamping, the first and second conveyor belts 303 and 304 move forward synchronously. After reaching the positions of the inner pad feeding mechanism 2 and the inner pad pressing mechanism 4, the first and second conveyor belts 303 and 304 stop moving. Then, the first conveyor belt 303 moves slightly in the reverse direction, and the second conveyor belt 304 continues to move slightly in the forward direction. At this time, the left and right clamping parts separate, and the bottle body 8 is released.

[0060] Working principle: 1. During the forward movement of the bottle body 8 driven by the mold conveying mechanism 3, the inner pad 9 on the second inner pad temporary receiving platform 205 is moved into the bottle body 8 via the inner pad feeding mechanism 2 and the inner pad suction cup 202, completing the transfer of two inner pads 9 at the same time. During the transfer, the bottle body 8 is clamped by the limiting clamping mechanism. After the transfer is completed, the limiting clamping mechanism releases the clamped bottle body 8, and the clamping part 301 on the mold conveying mechanism 3 takes over the clamping.

[0061] 2. The mold conveying mechanism 3 drives the bottle body 8 to continue moving forward to the inner pad pressing mechanism 4. After being pressed by the pressing belt pulley 401, it is transferred to the inner pad detection mechanism 5, the non-conforming product unloading mechanism 6, and the inner pad cleaning mechanism 7 in sequence, completing the inner pad 9 detection, non-conforming product unloading and inner pad 9 cleaning operations. The relevant working principle has been described above, and will not be elaborated further here.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
