Description

Technical Field

[0001] This invention relates to the field of thermos cup processing technology, and in particular to a conveying device for thermos cup production lines. Background Technology

[0002] In the production and processing of thermos cups, robotic arms are often used to transfer and transport thermos cups between two processing steps. After each processing step is completed, the processed thermos cups are inspected for quality. The thermos cups that pass the inspection are transported to the next processing stage, while the thermos cups that fail the inspection are kicked off the thermos cup conveyor line. The subsequent operation of the robotic arms will cause gaps in the thermos cups on the conveyor line, affecting the processing efficiency of the thermos cups in the subsequent processing. At the same time, when the robotic arms place the thermos cups on the conveyor line, the thermos cups are prone to sliding and shifting due to the operation of the conveyor line, resulting in the thermos cups on the conveyor line being disordered, which affects the gripping and transportation of the thermos cups by the subsequent robotic arms, resulting in low processing efficiency.

[0003] Therefore, in view of this situation, it is necessary to develop a conveying device for thermos cup production lines to meet the needs of actual use. Summary of the Invention

[0004] The purpose of this invention is to provide a conveying device for a thermos cup production line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for a thermos cup production line, comprising a bracket, a conveying unit mounted on the upper part of the bracket, a first limiting frame fixed to the side wall of the bracket via a connecting frame, a conveying platform mounted on the bracket, and a transfer platform located between the conveying platform and the conveying unit fixed to the bracket via a connecting frame. A first support frame is slidably mounted on the transfer platform and a second support frame is fixedly mounted thereon. Both the first and second support frames are fixedly mounted with a first fixing plate. A first sliding block is slidably mounted on the first fixing plate, with the opposing sides of the two first sliding blocks being inclined surfaces. An electric push rod is fixedly mounted on the upper surface of the first fixing plate, and the telescopic end of the electric push rod is fixedly mounted to an adjacent first sliding block. A second sliding block is slidably mounted on the side of the first fixing plate away from the first sliding block. A spur gear is rotatably mounted on the first fixing plate. Both the first and second sliding blocks are fixedly mounted with racks, and the spur gear meshes with an adjacent rack. An adjustment mechanism for adjusting the movement of the first support frame is provided on the bracket.

[0006] Furthermore, the adjustment mechanism includes a first threaded rod, which is threaded onto the bracket. The bracket is fixedly connected to a telescopic rod, and the telescopic end of the telescopic rod is fixedly connected to a second limiting frame. The second limiting frame is rotatably connected to the first threaded rod and is also fixedly connected to the first support frame.

[0007] Furthermore, it also includes a blocking mechanism for blocking the insulated cups conveyed on the conveying unit. The blocking mechanism is disposed on the first limiting frame. A support platform is fixedly connected to the side wall of the support, and a fixed frame is fixedly connected to the support platform. The blocking mechanism includes an n-shaped frame, which is fixedly connected to the first limiting frame. A first sliding frame is slidably disposed on the n-shaped frame, and a second sliding frame is slidably disposed on the first sliding frame. A tension spring is installed between the first sliding frame and the second sliding frame. A first rotating shaft is rotatably disposed on the first support frame through a connecting frame. One end of the first rotating shaft is connected to the conveying unit through a sprocket and a chain drive. A turntable is fixedly connected to the other end of the first rotating shaft. The turntable is provided with an elliptical groove. A sliding frame slides within an elliptical groove on the turntable. Both the first and second limiting frames are slidably equipped with a third limiting frame via an L-shaped frame. Springs are installed between the L-shaped frames on the first and second limiting frames and adjacent third limiting frames. The two third limiting frames cooperate to intercept the thermos cup. The second sliding frame is fixedly connected to two symmetrical first fixing rods. The third limiting frame has an inclined surface that presses against the adjacent first fixing rod. The first sliding frame is equipped with a pushing component for pushing the thermos cup into the fixed frame. The fixed frame is equipped with a limiting component for restricting the thermos cup. The support platform is equipped with a replenishing component for pushing the thermos cup out of the fixed frame.

[0008] Furthermore, the pushing assembly includes a second fixed plate, which is fixedly connected to the first support frame. The second fixed plate is provided with a U-shaped groove, and the second sliding frame slides within the U-shaped groove of the second fixed plate. The second fixed plate is fixedly connected to a first fixed shell, and a third sliding frame is slidably mounted on the first fixed shell. A spring is installed between the third sliding frame and the first fixed shell. The third sliding frame is provided with a swing plate for limiting its swing. The second sliding frame and the swing plate on the third sliding frame are in a pressing fit. The first support frame is fixedly connected to a second fixed shell, and the second fixed shell and the first fixed shell are connected by a pipe. The second fixed shell, the first fixed shell, and the pipe between them are all filled with liquid. A first sliding push plate is slidably mounted on the second fixed shell, and the first sliding push plate faces the fixed frame.

[0009] Furthermore, the limiting component includes a third fixing plate, which is fixedly connected to the fixing frame. The third fixing plate is rotatably provided with a rotating column, which is provided with circumferentially equidistant limiting holes. The third fixing plate is slidably provided with a first sliding column, and a tension spring is installed between the first sliding column and the third fixing plate. The first sliding column and the adjacent limiting holes on the rotating column are in a limiting engagement. The rotating column is fixedly connected with four circumferentially equidistant second fixing rods. The fixing frame is rotatably provided with a second threaded rod, which is driven by a bevel gear set. The second threaded rod is threaded with a limiting plate that slides within the fixing frame.

[0010] Furthermore, the feeding assembly includes a third fixed shell, which is fixedly connected to the support platform. A fourth sliding frame is slidably disposed on the third fixed shell. A spring is installed between the fourth sliding frame and the third fixed shell, and the fourth sliding frame is in a pressing fit with the second sliding frame. The limiting plate is fixedly connected to the fourth fixed shell. The fourth fixed shell and the third fixed shell are connected by a hose. The fourth fixed shell, the third fixed shell, and the pipe between them are all filled with liquid. A sliding plate is slidably disposed inside the fourth fixed shell. A second sliding push plate is slidably disposed on the side of the fourth fixed shell near the rotating column. The second sliding push plate is located between the sliding plate and the rotating column, and a spring is installed between the second sliding push plate and the sliding plate.

[0011] Furthermore, the elastic force stored in the spring connected to the second sliding push plate is less than the limiting force of the first sliding column on the rotating column.

[0012] Furthermore, it also includes a drive mechanism for controlling the conveying rate of the thermos cup by the conveying unit. The drive mechanism is mounted on the bracket and includes a drive motor fixed to the bracket. The output shaft of the drive motor passes through the bracket and is rotatably connected to it. The output shaft of the drive motor is fixed to a second rotating shaft. A third rotating shaft is rotatably mounted on the side wall of the bracket. Both the second and third rotating shafts are fixed to a first frustum wheel. Both the second and third rotating shafts are provided with spline grooves. The spline grooves of the second and third rotating shafts are slidably provided with second frustum wheels. The two first frustum wheels and the two second frustum wheels are centrally symmetrical. A transmission belt that fits the two first frustum wheels and the two second frustum wheels is wound between the second and third rotating shafts. The third rotating shaft is connected to the conveying unit by a sprocket and a chain. A speed regulating component is provided on the support platform for adjusting the transmission ratio between the second and third rotating shafts.

[0013] Furthermore, the speed regulating component includes two symmetrical fifth fixed shells, both of which are fixed to the lower surface of the support platform. A fifth sliding frame is slidably mounted on each fifth fixed shell, penetrating the support platform and slidably connected to it. A fixed frame is fixedly mounted on the side of the bracket closest to the support platform. A sixth fixed shell is fixedly mounted on the fixed frame. The two fifth fixed shells and the sixth fixed shell are connected by pipes. Liquid is filled in the two fifth fixed shells, the sixth fixed shell, and the pipes between them. A sliding rod is slidably mounted on the fixed frame, sliding within the sixth fixed shell. A second sliding column is slidably mounted on the fixed frame. A tension spring is installed between the second sliding column and the fixed frame. The sliding rod has two blind holes. The second sliding column and the adjacent blind holes on the sliding rod are mutually limiting fits. A sliding ring is slidably mounted on the sixth fixed shell, slidingly fitting with the sliding rod. A spring is installed between the sliding ring and the sliding rod. A third support frame is fixedly mounted on the sliding rod, and the third support frame is rotatably connected to two second frustum wheels.

[0014] Furthermore, the limiting force of the second sliding column on the sliding rod is greater than the elastic force stored by the sliding ring pressing against the connected spring when the single fifth sliding frame moves.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention controls the evenly spaced distribution of thermos cups on the conveying platform by the alternating opening and closing of two first sliding blocks and two second sliding blocks, thereby improving the subsequent processing efficiency of thermos cups. The guide limit of the first limiting frame keeps the thermos cups neat. The movement of the first sliding push plate facilitates pushing the thermos cups into the fixed frame to complete the storage of the thermos cups. The position of the limiting plate is adjusted by the movement of the rotating column to ensure that the second sliding push plate is in real time in contact with the thermos cups in the fixed frame. In conjunction with the movement of the second sliding push plate, it is convenient to push the thermos cups stored in the fixed frame back onto the conveying unit, avoiding the phenomenon of broken parts and gaps in the thermos cups on the conveying line, thereby indirectly improving the subsequent processing efficiency of thermos cups. The number of thermos cups in the fixed frame is detected by two fifth sliding frames, and the transmission ratio of the transmission belt between the second and third rotating shafts is adjusted by the movement of the third support frame. The spacing between the conveyed thermos cups is automatically controlled, thereby ensuring the stability of the thermos cup conveying and further indirectly improving the subsequent processing efficiency.

[0018] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings of the embodiments will be briefly described below. Obviously, the drawings described below only relate to some embodiments of the present invention and are not intended to limit the present invention.

[0019] Example 1: A conveying device for a thermos cup production line, such as Figures 1-4As shown, the system includes a support frame 1, a conveying unit 11 mounted on the upper part of the support frame 1, a control panel fixed to the front side of the support frame 1, and a first limiting frame 12 fixed to the rear side wall of the support frame 1 via a connecting frame. The first limiting frame 12 tilts forward from right to left to facilitate the subsequent operation of the conveying unit 11, ensuring that the thermos cups on it remain neat under the limiting action of the first limiting frame 12. A conveying platform 13 electrically connected to the control panel is mounted on the left side of the support frame 1. A transfer platform 15 is fixed to the left side of the support frame 1 via a connecting frame, and the transfer platform 15 is located between the conveying platform 13 and the conveying unit 11. A first support frame 16 is slidably mounted on the upper surface of the transfer platform 15 and a second support frame 17 is fixedly mounted thereon. The first support frame 16 is located in front of the second support frame 17. A first fixing plate 18 is fixedly mounted on the upper surface of both the first support frame 16 and the upper surface of the second support frame 17. A first sliding block 19 is slidably mounted on the right side of the first fixing plate 18. Both sides of the first sliding block 19 are set as inclined surfaces. The inclined surfaces of the two first sliding blocks 19 approach each other from left to right. An electric push rod 191 electrically connected to the control panel is fixed to the upper surface of the first fixed plate 18. The telescopic end of the electric push rod 191 is fixed to the adjacent first sliding block 19. A second sliding block 192 is slidably arranged on the left side of the first fixed plate 18. Both the second sliding block 192 and the first sliding block 19 are provided with arc-shaped surfaces for contacting and limiting the thermos cup. A spur gear 193 is rotatably arranged on the lower part of the first fixed plate 18. A rack 194 that meshes with the adjacent spur gear 193 is fixed to the left side of the first sliding block 19 and the right side of the second sliding block 192. An adjustment mechanism for adjusting the movement of the first support frame 16 is provided on the bracket 1. By using the staggered opening and closing of the two first sliding blocks 19 and the two second sliding blocks 192, the thermos cups are evenly distributed at equal intervals on the conveying platform 13, ensuring continuous processing of the thermos cups in the future, thereby improving processing efficiency.

[0020] like Figure 2 As shown, the adjustment mechanism includes a first threaded rod 2, which is threaded onto a bracket 1. A telescopic rod 21 is fixedly connected to the bracket 1. The telescopic end of the telescopic rod 21 is fixedly connected to a second limiting frame 22 that is rotatably connected to the rear end of the first threaded rod 2. The left side of the second limiting frame 22 is fixedly connected to the first support frame 16. The first limiting frame 12 and the second limiting frame 22 cooperate to limit and support the conveyed thermos cup, ensuring that the thermos cup is stable during the conveying process.

[0021] When conveying the processed and inspected thermos cups, the thermos cups that have passed the sealing inspection are placed on the conveying unit 11, which is connected to an external servo motor. During the conveying process, the control panel starts the external servo motor, the conveying platform 13 and the two electric push rods 191 connected to the conveying unit 11. The conveying unit 11 works to convey the thermos cup to the left, and then the thermos cup moves to the subsequent processing step. During the above conveying process, the first limit frame 12 and the second limit frame 22 limit the left and right sides of the thermos cup to keep the thermos cup stable during the conveying process. When the thermos cup moves to the two second sliding blocks 192, the two second sliding blocks 192 limit the thermos cup.

[0022] During the operation of the conveying unit 11, the control panel on the bracket 1 controls two electric push rods 191 to perform intermittent reciprocating work. The operation of the two electric push rods 191 drives the adjacent first sliding blocks 19 to move. At this time, the two first sliding blocks 19 approach each other. The movement of the first sliding blocks 19 drives the adjacent second sliding blocks 192 to move through the two adjacent racks 194 and the adjacent spur gears 193. At this time, the two second sliding blocks 192 move away from each other, releasing the restriction on the adjacent thermos cups. During this process, the two first sliding blocks 19 approach each other, causing their upper inclined surfaces to press the thermos cups located on the transfer platform 15 to continue moving to the left, so that the thermos cups move to the conveying platform 13. At this time, the conveying platform 13 conveys the thermos cups located on it to the left, so that the thermos cups enter the downward processing stage.

[0023] After the telescopic ends of the two electric push rods 191 are fully extended, the control panel controls the telescopic ends of the two electric push rods 191 to move in the opposite direction to reset. During this process, the two second sliding blocks 192 gradually move closer together, while the two first sliding blocks 19 gradually move away from each other. The two first sliding blocks 19 moving away from each other releases the restriction on the thermos cups conveyed on the conveying unit 11. Subsequently, under the conveying action of the conveying unit 11, the thermos cups move and fit against the right side of the two second sliding blocks 192. During the above conveying process, the conveying efficiency of the conveying unit 11 for the thermos cups is higher than that of the conveying platform 13 for the thermos cups. The thermos cups on the conveying unit 11 accumulate on the right side of the two second sliding blocks 192. Subsequently, the two electric push rods 191 repeat the above reciprocating work. The two second sliding blocks 192 and the two first sliding blocks 19 open and close alternately, so that the thermos cups are conveyed evenly at equal intervals on the conveying platform 13, which facilitates continuous and precise processing of the thermos cups in subsequent processing stages and improves processing efficiency.

[0024] In this thermos cup conveyor line, when conveying thermos cups of different specifications, the operator rotates the first threaded rod 2, which drives the second limiting frame 22 to move, changing the distance between the second limiting frame 22 and the first limiting frame 12. The length of the telescopic rod 21 changes accordingly, which facilitates the conveying of thermos cups of different specifications and improves the applicability of the device. After the thermos cup processing is completed, the operator turns off the conveying unit 11, the conveying platform 13 and the two electric push rods 191 through the control panel.

[0025] Example 2: Based on Example 1, such as Figure 1 and Figures 5-7As shown, it also includes a blocking mechanism for blocking the thermos cups conveyed on the conveying unit 11. The blocking mechanism is disposed on the first limiting frame 12. A support platform 36 is fixedly connected to the rear side of the support 1. A fixing frame 37 for storing thermos cups is fixedly connected to the support platform 36. The blocking mechanism includes an n-shaped frame 3, which is fixedly connected to the upper surface of the first limiting frame 12. A first sliding frame 31 is slidably disposed on the n-shaped frame 3. A limiting groove is provided on the right side of the first sliding frame 31. A second sliding frame 311 is slidably disposed on the first sliding frame 31. The second sliding frame 311 is located at the limiting groove of the first sliding frame 31. Two symmetrical tension springs are installed between the moving frame 31 and the second sliding frame 311. A first rotating shaft 32 is rotatably mounted on the front of the first support frame 16 via a connecting frame. The front end of the first rotating shaft 32 is connected to the conveying unit 11 via a sprocket and chain drive. By setting the transmission ratio between the sprocket and chain, the rotation frequency of the first rotating shaft 32 corresponds to the spacing between the conveyed thermos cups. A turntable 33 is fixedly connected to the rear end of the first rotating shaft 32. An elliptical groove is provided at the rear of the turntable 33. The first sliding frame 31 slides within the elliptical groove of the turntable 33. Both the first limiting frame 12 and the second limiting frame 22... A third limiting frame 34 is slidably mounted on an L-shaped frame. The two third limiting frames 34 are symmetrically distributed front and back. Two symmetrical springs are installed between the L-shaped frames on the first limiting frame 12 and the L-shaped frames on the second limiting frame 22 and the adjacent third limiting frames 34, respectively. The two third limiting frames 34 cooperate to intercept the thermos cup. The front and rear parts of the second sliding frame 311 are fixedly connected to the first fixing rods 35, which are symmetrically distributed front and back. The upper part of the third limiting frame 34 is provided with an inclined surface that presses against the adjacent first fixing rod 35. The inclined surfaces on the two third limiting frames 34 move away from each other from top to bottom. The first sliding frame 31 is equipped with a pushing component for pushing the thermos cup into the fixed frame 37. The fixed frame 37 is equipped with a limiting component for restricting the thermos cup. The support platform 36 is equipped with a replenishing component for pushing the thermos cup out of the fixed frame 37. The thermos cup is limited by two third limiting frames 34. The placement frequency of the thermos cup is detected by the second sliding frame 311. This facilitates subsequent control of the thermos cups in the fixed frame 37 or the replenishment of the thermos cups in the fixed frame 37 onto the conveying unit 11. This effectively controls the spacing of the thermos cups on the conveying platform 13, thereby indirectly improving the processing efficiency of the thermos cups.

[0026] like Figure 5 , Figure 8 and Figure 9As shown, the pushing assembly includes a second fixed plate 41, which is fixed to the upper surface of the first support frame 16. A U-shaped groove is provided on the upper part of the second fixed plate 41. A second sliding frame 311 slides within the U-shaped groove of the second fixed plate 41. A first fixed shell 42 is fixed to the front side of the second fixed plate 41. A third sliding frame 43 is slidably disposed on the upper part of the first fixed shell 42. A spring is installed between the third sliding frame 43 and the first fixed shell 42. A swing plate is provided on the upper part of the third sliding frame 43 in a limiting swing configuration. The swing plate on the third sliding frame 43 is located on the left side of the U-shaped groove on the second fixed plate 41. The second sliding frame 311 and the swing plate on the third sliding frame 43 are press-fitted. In the initial state, the swing plate on the third sliding frame 43 is in a horizontal state, and the swing plate on the third sliding frame 43 can only swing upwards from the horizontal state. A second fixed shell 44, which is connected to the first fixed shell 42 via a pipe, is fixed to the lower surface of the frame 16. The second fixed shell 44, the first fixed shell 42, and the pipe between them are all filled with liquid. A first sliding push plate 45 is slidably disposed on the left side of the second fixed shell 44. The first sliding push plate 45 is directly opposite the fixed frame 37. When the second sliding frame 311 is squeezed by the thermos cup, the second sliding frame 311 passes through the lower part of the U-shaped groove on the second fixed plate 41. Then the second sliding frame 311 slides into the left side of the U-shaped groove on the second fixed plate 41. When the second sliding frame 311 moves down to reset, the second sliding frame 311 will squeeze the swing plate on the third sliding frame 43. Then the third sliding frame 43 extends the first sliding push plate 45 through the connected parts, so as to push the thermos cup directly opposite the first sliding push plate 45 into the fixed frame 37 to complete the storage of the thermos cup.

[0027] like Figures 10-12 As shown, the limiting assembly includes a third fixing plate 5, which is fixed to the front of the left side of the fixing frame 37. The third fixing plate 5 is rotatably provided with a rotating column 51. The lower part of the rotating column 51 is provided with four circumferentially equidistant limiting holes. The rear part of the third fixing plate 5 is slidably provided with a first sliding column 52 that cooperates with the adjacent limiting holes on the rotating column 51. A tension spring is installed between the first sliding column 52 and the third fixing plate 5. The upper part of the rotating column 51 is fixed with four circumferentially equidistant second fixing rods 53. The left side of the fixing frame 37 is rotatably provided with a second threaded rod 55. The second threaded rod 55 is driven by a bevel gear set. The second threaded rod 55 is threaded with a limiting plate 56, and the limiting plate 56 is located within the fixing frame 37 and slides in a limiting manner. The limiting plate 56 keeps the thermos cup neat within the fixing frame 37.

[0028] like Figure 10 , Figure 12 and Figure 13As shown, the feeding assembly includes a third fixed housing 6, which is fixed to the upper surface of the support platform 36. A fourth sliding frame 61, which is pressed against the second sliding frame 311, is slidably disposed on the upper part of the third fixed housing 6. A spring is installed between the fourth sliding frame 61 and the third fixed housing 6. A limiting plate 56 is fixed to the fourth fixed housing 62. The fourth fixed housing 62 and the third fixed housing 6 are connected by a hose. The fourth fixed housing 62, the third fixed housing 6, and the pipe between them are all filled with liquid. A sliding plate 63 is slidably disposed inside the fourth fixed housing 62. A second sliding push plate 64 is slidably disposed at the front of the fourth fixed housing 62. The sliding plate 63 is located behind the second sliding push plate 64. A spring is installed between the sliding push plate 64 and the sliding plate 63. The elastic coefficient of the spring between the fourth sliding frame 61 and the third fixed shell 6 is greater than that between the second sliding push plate 64 and the sliding plate 63. The elastic force stored by the second sliding push plate 64 moving and pressing the connected spring is less than the limiting force of the first sliding column 52 on the rotating column 51. When the second sliding frame 311 is not pressed by the thermos cup, the first sliding frame 31 moves up and down reciprocally. At this time, the second sliding frame 311 is facing the fourth sliding frame 61. The first sliding frame 31, through the connected parts, causes the second sliding push plate 64 to push a thermos cup in the fixed frame 37 onto the conveying unit 11, controlling the spacing between the conveyed thermos cups.

[0029] During the conveying process of the thermos cup by the conveying unit 11, in the initial state, the control panel controls the conveying unit 11 to quickly convey the qualified thermos cup. The conveying unit 11 quickly conveys the thermos cup to the left. When the thermos cup moves to the left and fits against the right side of the two third limit frames 34, the thermos cup moves and squeezes the adjacent second sliding frame 311. The second sliding frame 311 is squeezed and stretches the adjacent tension spring, and the second sliding frame 311 moves to the left part of the U-shaped groove on the second fixed plate 41. The conveying unit 11 continues to work and drives the adjacent first rotating shaft 32 to rotate through the adjacent sprocket and chain. The rotation of the first rotating shaft 32 drives the turntable 33 to rotate. The rotation of the turntable 33 causes the elliptical groove on it to squeeze the first sliding frame 31, so that the first sliding frame 31 drives the connected parts to move upward. The upward movement of the first sliding frame 31 drives the second sliding frame 311 to pass through the swing plate on the third sliding frame 43, so that the second sliding frame 311 is above the third sliding frame 43.

[0030] During the upward movement of the first sliding frame 31, the second sliding frame 311, located on the left side of the U-shaped groove on the second fixed plate 41, moves upward. The movement of the first sliding frame 31 and the second sliding frame 311 gradually releases the restriction on the thermos cup. The movement of the second sliding frame 311 also presses the swing plate on the third sliding frame 43, causing the second sliding frame 311 to pass through the swing plate on the third sliding frame 43. Subsequently, the swing plate on the third sliding frame 43 swings back to its original position. The movement of the second sliding frame 311 simultaneously drives the two first fixed rods 35 to move upward. The upward movement of the first fixed rods 35 presses the inclined surface of the adjacent third limiting frame 34. At this time, the two third limiting frames 34 move away from each other and compress the adjacent springs. The movement of the two third limiting frames 34 releases the restriction on the thermos cup. Subsequently, the conveying unit 11 works to convey the thermos cup to the transfer platform 15.

[0031] During the operation of the conveying unit 11, the two electric push rods 191 repeat the above operation, causing the two first sliding blocks 19 and the two second sliding blocks 192 to open and close alternately, controlling the thermos cups to be conveyed at equal intervals on the conveying platform 13. Since the conveying efficiency of the conveying unit 11 is greater than the working frequency of the electric push rods 191, when the thermos cups are piled up on the transfer platform 15, as the first sliding frame 31 repeats its up-and-down reciprocating operation, the thermos cups blocked by the first sliding frame 31 will move to the left and fit against the thermos cups on the transfer platform 15.

[0032] After the first sliding frame 31 moves to its upper limit, the turntable 33 continues to rotate, causing its elliptical groove to press the first sliding frame 31 downward and reset. The downward movement of the first sliding frame 31 drives the connected parts to move in the opposite direction and reset. Under the elastic force of the spring on the third limiting frame 34, it moves in the opposite direction and resets. At this time, the two third limiting frames 34 intercept the thermos cups conveyed on the subsequent conveying unit 11 again. During the process of the first sliding frame 31 driving the second sliding frame 311 downward, the second sliding frame 311 presses the swing plate on the third sliding frame 43. This swing plate cannot swing downward around the third sliding frame 43. The movement of the second sliding frame 311 will press the third sliding frame 43 downward in the first fixed shell 42 and compress the adjacent spring. The movement of the third sliding frame 43 will press the liquid in the first fixed shell 42 into the second fixed shell 44 through the pipe. As the liquid flows, the liquid will press the first sliding push plate 45 to move backward. The movement of the first sliding push plate 45 will push the thermos cup behind it to move into the fixed frame 37.

[0033] When the first sliding push plate 45 pushes the thermos cup backward, the thermos cup first moves and presses against the adjacent second fixed rod 53. The second fixed rod 53 is pressed and drives the rotating column 51 to rotate counterclockwise. During this process, the rotation of the rotating column 51 causes the blind hole on its upper rear side to press against the first sliding column 52. The first sliding column 52 is pressed and moves backward and stretches the adjacent tension spring. After the first sliding push plate 45 has finished moving, the rotating column 51 rotates to nearly 90°. Then, under the tension of the tension spring on the first sliding column 52, the first sliding column 52 is reinserted into the adjacent blind hole on the rotating column 51. After the rotating column 51 has finished rotating, the second fixed rod 53 rotates to be perpendicular to the fixed frame 37. The second fixed rod 53 simultaneously limits the thermos cup located in the fixed frame 37.

[0034] When the rotating column 51 rotates, it drives the second threaded rod 55 to rotate through the bevel gear set. The rotation of the second threaded rod 55 causes the limiting plate 56 to move the connected parts backward. At this time, the thermos cup is located between the second sliding push plate 64 and the adjacent second fixed rod 53. During the process of the thermos cup being located in the fixed frame 37, the thermos cup simultaneously squeezes the second sliding push plate 64 to move backward relative to the fourth fixed shell 62. Due to the limiting effect of the liquid in the third fixed shell 6 and the liquid in the fourth fixed shell 62, the sliding plate 63 remains fixed relative to the fourth fixed shell 62. At this time, the second sliding push plate 64 moves to squeeze the connected spring.

[0035] Under the continuous operation of the conveying unit 11, a large number of thermos cups are pushed into the fixed frame 37. After the fixed frame 37 is full of thermos cups, the operator controls the working frequency of the external servo motor connected to the conveying unit 11 through the control panel. Then, when the front detection unit detects that the thermos cups are unqualified, the interval between the thermos cups conveyed by the conveying unit 11 is too large. When the thermos cups are not in contact with the first sliding frame 31 and the two third limit frames 34, the first rotating shaft 32 drives the turntable 33 to perform the above-mentioned rotation operation. At this time, under the tension of the tension spring on the second sliding frame 311, the first sliding frame 31 drives the second sliding frame 311 and other connected parts to move up and down reciprocally. At this time, the second sliding frame 311 first moves into the right part of the U-shaped groove on the second fixed plate 41. The first fixed rod 35 intersects with the inclined surface of the adjacent third limit frame 34. At the same time, the rear part of the second sliding frame 311 is located below the fourth sliding frame 61. Subsequently, the first sliding frame 31 continues to move up and down reciprocally.

[0036] The movement of the first sliding frame 31 causes the second sliding frame 311 to move upward and compress the fourth sliding frame 61. The fourth sliding frame 61 moves upward and compresses the adjacent spring. The upward movement of the fourth sliding frame 61 compresses the liquid in the third fixed shell 6 and enters the fourth fixed shell 62 through the hose. The liquid compresses the sliding plate 63 to move forward relative to the fourth fixed shell 62 and compresses the adjacent spring. Under the elastic force of the spring between the sliding plate 63 and the second sliding push plate 64, the second sliding push plate 64 pushes the thermos cup between the fixed frames 37 forward. At this time, the pushing force of the second sliding push plate 64 is greater than the limiting force of the first sliding column 52 on the rotating column 51, so that the thermos cup at the front of the fixed frame 37 enters the conveying unit 11.

[0037] During the process of the second sliding push plate 64 pushing the thermos cup, the thermos cup presses against the adjacent second fixed rod 53, causing the rotating column 51 to perform the opposite operation. The rotating column 51 reverses and drives the limiting plate 56 and the connected parts forward together through the bevel gear set and the second threaded rod 55, so that the second sliding push plate 64 always fits against the thermos cup under the elastic force of the spring on it. At the same time, the rotating column 51 reverses and moves the corresponding second fixed rod 53 to the front side of the second thermos cup from the front to the back in the fixed frame 37. The second fixed rod 53 re-limits the thermos cup in the fixed frame 37. Subsequently, under the tension of the connected tension spring, the first sliding column 52 is inserted into the corresponding blind hole on the rotating column 51. After the thermos cups in the fixed frame 37 are replenished to the conveying unit 11, the thermos cups are effectively controlled to maintain equal spacing and continuity on the conveying platform 13, thereby indirectly improving the processing efficiency of the qualified thermos cups.

[0038] Example 3: Based on Example 2, such as Figure 14 and Figure 15As shown, it also includes a drive mechanism for controlling the conveying rate of the thermos cup by the conveying unit 11. The drive mechanism is mounted on the bracket 1 and includes a drive motor 7 electrically connected to the control panel. The drive motor 7 is fixed to the bracket 1 via a fixed base. The output shaft of the drive motor 7 penetrates the bracket 1 and is rotatably connected to it. The output shaft of the drive motor 7 is fixedly connected to a second rotating shaft 71. A third rotating shaft 72 is rotatably mounted on the side wall of the bracket 1. The third rotating shaft 72 is located above the second rotating shaft 71. Both the second rotating shaft 71 and the third rotating shaft 72 are fixedly connected to a first frustum wheel 73. The two first frustum wheels 73 are centrally symmetrical. Both the second rotating shaft 71 and the third rotating shaft 72 are provided with spline grooves. Each of the two second truncated rollers 74 is slidably arranged, and the two second truncated rollers 74 are centrally symmetrical. A transmission belt is wound between the second rotating shaft 71 and the third rotating shaft 72, which fits the two first truncated rollers 73 and the two second truncated rollers 74. The first truncated rollers 73, the second truncated rollers 74 and the transmission belt are equivalent to a traditional continuously variable transmission. The third rotating shaft 72 is connected to the conveying unit 11 by a sprocket and a chain. The support platform 36 is equipped with a speed regulating component for adjusting the transmission ratio between the second rotating shaft 71 and the third rotating shaft 72. The conveying unit 11 is driven by the drive motor 7, and the speed regulating component mechanically detects the position of the thermos cups to control the transmission ratio between the second rotating shaft 71 and the third rotating shaft 72, thereby automatically adjusting the distance between the conveyed thermos cups.

[0039] like Figure 14 and Figure 16As shown, the speed regulating assembly includes two symmetrical fifth fixed shells 8, both of which are fixed to the lower surface of the support platform 36. A fifth sliding frame 81 is slidably mounted on the upper part of the fifth fixed shell 8. The upper part of the fifth sliding frame 81 is frustoconical, and the fifth sliding frame 81 penetrates the support platform 36 and is slidably connected to it. A fixed frame 82 is fixedly mounted on the rear side of the bracket 1, and a sixth fixed shell 83 is fixedly mounted on the rear part of the fixed frame 82. The two fifth fixed shells 8 and the sixth fixed shell 83 are connected by pipes. The two fifth fixed shells 8, the sixth fixed shell 83, and the pipes between them are all filled with liquid. A sliding rod 84 is slidably mounted on the fixed frame 82, and the rear part of the sliding rod 84 slides inside the sixth fixed shell 83. The sliding rod 84 has two symmetrical blind holes. The upper part of the fixed frame 82 is slidably mounted with holes corresponding to the upper part of the sliding rod 84. The second sliding post 85 is fitted with a blind hole limit. A tension spring is installed between the second sliding post 85 and the fixed frame 82. A sliding ring 86 is slidably arranged on the sixth fixed shell 83, which is slidably fitted with the sliding rod 84. A spring is installed between the sliding ring 86 and the sliding rod 84. The limiting force of the second sliding post 85 on the sliding rod 84 is greater than the elastic force stored by the sliding ring 86 moving and squeezing the spring connected to it when a single fifth sliding frame 81 moves. The front end of the sliding rod 84 is fixedly connected to a third support frame 87 that is rotatably connected to both second frustum wheels 74. The number of thermos cups in the fixed frame 37 is detected by the two fifth sliding frames 81 being pressed together or not pressed together, so as to adjust the conveying speed of the conveying unit 11 in real time. This facilitates the subsequent use of thermos cups in the fixed frame 37 to further fill the gaps in the conveyed thermos cups, ensuring that the thermos cups are conveyed at equal distances.

[0040] During the conveying of the processed thermos cups, the operator starts the drive motor 7, the conveying platform 13 and the two electric push rods 191 through the control panel. The drive motor 7 drives the second rotating shaft 71 to rotate. The rotation of the second rotating shaft 71 drives the third rotating shaft 72 to rotate through the two first truncated rollers 73, the two second truncated rollers 74 and the transmission belt. The rotation of the third rotating shaft 72 drives the conveying unit 11 to work through the adjacent sprockets and chains. In the initial state, the second sliding column 85 is located in the blind hole on the rear side of the sliding rod 84. At this time, the transmission belt between the second rotating shaft 71 and the third rotating shaft 72 has an acceleration structure, which enables the conveying unit 11 to quickly convey the thermos cups placed on it.

[0041] Under the rapid conveying action of the conveying unit 11, the above-mentioned operation of accumulating a large number of thermos cups in the fixed frame 37 is repeated. At the same time, the conveying platform 13 conveys the thermos cups distributed at equal intervals at a uniform speed. When the thermos cups enter the fixed frame 37, the fixed frame 37 will first squeeze the fifth sliding frame 81 on the front side. The fifth sliding frame 81 is squeezed and compressed into the fixed frame 37 by the thermos cups. The fifth sliding frame 81 moves and squeezes the liquid in the adjacent fifth fixed shell 8 through the pipe into the sixth fixed shell 83. The liquid flow squeezes the sliding ring 86 to move and compress the adjacent spring. At this time, the elastic force of the spring on the sliding ring 86 is less than the limiting force of the second sliding column 85 on the sliding rod 84. Then the thermos cups continue to accumulate in the fixed frame 37.

[0042] When the thermos cup is pressed against the fifth sliding bracket 81 on the rear side, the fifth sliding bracket 81 moves and presses the liquid in the adjacent fifth fixed shell 8. The liquid in the fifth fixed shell 8 enters the sixth fixed shell 83, causing the sixth fixed shell 83 to move again and compress the adjacent spring. At this time, under the elastic force of the spring connected to the sliding rod 84, the sliding rod 84 moves backward and presses the second sliding column 85 to move accordingly. The second sliding column 85 moves and stretches the connected tension spring. When the blind hole on the front side of the sliding rod 84 is directly opposite the second sliding column 85, the tension of the tension spring on the second sliding column 85... The sliding rod 84 is re-inserted into the blind hole on the front side by reversing its movement. The movement of the sliding rod 84 drives the adjacent third support frame 87 and the two second truncated rollers 74 to move backward together. The movement of the two second truncated rollers 74 reduces the transmission ratio of the transmission belt between the second rotating shaft 71 and the third rotating shaft 72. The subsequent drive motor 7 works to slow down the conveying speed of the conveying unit 11 through the connected parts. During this process, the conveying speed of the conveying unit 11 is automatically adjusted to avoid the gap between the conveyed thermos cups being too large due to the qualified inspection process, which would affect the subsequent processing efficiency of the conveyed thermos cups.

[0043] During the continuous conveying of thermos cups on the conveying platform 13, thermos cups in the fixed frame 37 are gradually replenished into the conveying line. When the thermos cup at the last side of the fixed frame 37 is in front of the fifth sliding frame 81 at the front, the thermos cup releases the pressure on the two fifth sliding frames 81. Under the elastic force of the springs connected to the fifth sliding frames 81, the two fifth sliding frames 81 move in opposite directions to reset. At the same time, the liquid in the sixth fixed shell 83 is drawn into the two fifth fixed shells 8. At this time, the liquid in the sixth fixed shell 83 decreases and returns to the initial state. In this state, the sliding ring 86 resets and stretches the connected spring. At this time, the tension of the spring is greater than the limit of the second sliding column 85 on the sliding rod 84, so that the sliding rod 84 performs the above-mentioned reverse operation and resets. At this time, the transmission belt between the second rotating shaft 71 and the third rotating shaft 72 resets again, so that the conveying speed of the conveying unit 11 increases. The above-mentioned thermos cup accumulation operation is repeated, and the thermos cup is pushed into the fixed frame 37. Then the above operation is repeated.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope provided by the present invention should be included within the scope of protection of the present invention.
