Description

Technical Field

[0001] This application relates to the technical field of double-sided printing on socks, and in particular to a locking mechanism for a double-sided printing flipping device for socks. Background Technology

[0002] Double-sided printing on socks is a technique that prints patterns or designs on both sides of the socks. This technique allows socks to have attractive designs on both the inside and outside, increasing their style and personalization.

[0003] Reference Figure 1 An existing technology for a double-sided printing and flipping device for socks includes a conveyor belt, a support plate, and a flipping plate located on a frame. The support plate is horizontally positioned on the conveyor belt, which is used to transport the support plate. The flipping plate is vertically positioned on the support plate and is rotatably connected to the support plate. The sock is placed on the flipping plate. After the worker finishes printing on one side of the sock, the worker rotates the flipping plate, thereby causing the sock to rotate and print on the other side of the sock.

[0004] In the aforementioned double-sided printing and flipping device for socks, after the worker finishes printing on one side of the sock, the worker flips the flipping plate. However, the flipping plate is not easy to rotate to the set angle, which requires the worker to manually adjust the flipping plate to rotate to the set angle for transmission. This process requires manual operation by the worker, which is time-consuming and labor-intensive. Utility Model Content

[0005] In order to eliminate the need for workers to manually rotate the flip plate to a set angle and save their workload, this application provides a locking mechanism for a double-sided printing flip device for socks.

[0006] The locking mechanism of the double-sided printing and flipping device for socks provided in this application adopts the following technical solution:

[0007] A locking mechanism for a double-sided printing and flipping device for socks includes a conveyor belt, a support plate, and a flipping plate located on a frame. The conveyor belt is horizontally arranged and connected to the frame. The support plate is located on the conveyor belt and connected to it. The flipping plate is located at the bottom of the support plate and connected to it. The device also includes a connecting plate, a lifting component, a drive motor, and a transmission component. The connecting plate is horizontally arranged and located on the frame, and it contacts the frame. The lifting component is located on the frame, connected to the connecting plate, and used to drive the connecting plate to move up and down. The drive motor is located on the connecting plate and connected to the frame. The output shaft of the drive motor is connected to the transmission component. The transmission component is located on the support plate and connected to the flipping plate, used to make the flipping plate rotate with the output shaft of the drive motor. A limit mechanism is provided on the support plate, and the limit mechanism is connected to the flipping plate and used to limit the flipping plate's movement.

[0008] By adopting the above technical solution, the staff starts the conveyor belt, which drives the support plate and flip plate to be transported, thereby printing on one side of the sock. When the support plate and flip plate are transported to the set position, the staff adjusts the lifting component to raise and lower the connecting plate to the set height. The staff then starts the drive motor, and the output shaft of the drive motor rotates. Through the transmission component, the flip plate rotates synchronously. When the flip plate rotates to the set angle, the limiting mechanism limits the flip plate, making it difficult for the flip plate to continue rotating. This makes it convenient for the staff to print on the other side of the sock, eliminating the need for the staff to manually adjust the flip plate to the set position, saving the staff's workload, time and effort. The limiting mechanism also improves the stability of the flip plate, making the sock less likely to move during printing, thereby improving the printing quality.

[0009] Preferably, the transmission component includes a rotating shaft and a transmission block. The rotating shaft is located at the bottom of the drive motor and is coaxially connected to the output shaft of the drive motor. A transmission groove is provided at the bottom of the rotating shaft and is vertically arranged. The transmission block is located at the top of the flip plate, and the bottom of the transmission block is connected to the flip plate. The top of the transmission block is used to contact the transmission groove.

[0010] By adopting the above technical solution, when the drive motor is raised to the set height, the output shaft of the drive motor rotates and drives the rotating shaft to rotate synchronously. Through the transmission groove and the transmission block, the connecting rod rotates with the transmission block, thereby driving the flip plate to rotate synchronously, so that the flip plate rotates to the set angle, thus making it convenient for the staff to print on the other side of the sock.

[0011] Preferably, the limiting mechanism includes a connecting rod, a limiting rod, and a driving component. The connecting rod is vertically arranged and located at the bottom of the transmission block. The top of the connecting rod is connected to the transmission block, and the bottom of the connecting rod is connected to the flap plate. A limiting groove is formed on the outer peripheral wall of the connecting rod, and the axial direction of the limiting groove is consistent with the radial direction of the connecting rod. The limiting rod is horizontally arranged, with one end connected to the support plate and the other end extending into the limiting groove and contacting the side wall of the limiting groove. The driving component is located on the support plate, and is connected to the limiting rod and is used to drive the limiting rod to move in a direction closer to or away from the limiting groove.

[0012] By adopting the above technical solution, when the connecting rod and the flap rotate to the set angle, the operator starts the drive mechanism, which causes the limit rod to move in the direction close to the limit groove until the side wall of the limit rod contacts the side wall of the limit groove, thereby limiting the connecting rod, the flap and the transmission block and improving the stability of the connecting rod.

[0013] Preferably, the driving component includes a first cylinder, which is located on a support plate, the cylinder body of the first cylinder is connected to the support plate, and the piston rod of the first cylinder is coaxially connected to a limiting rod.

[0014] By adopting the above technical solution, the staff starts the first cylinder, and the piston rod of the first cylinder extends and retracts, driving the limit rod to move synchronously until the side wall of the limit rod contacts the side wall of the limit groove, thereby limiting the connecting rod. No manual adjustment is required from the staff, saving time and effort.

[0015] Preferably, the lifting component includes a second cylinder and a lifting rod. The second cylinder is located at the top of the conveyor belt. The cylinder body of the second cylinder is connected to the frame. The piston rod of the second cylinder is vertically downward. The piston rod of the second cylinder is coaxially connected to the lifting rod. The lifting rod is vertically positioned, and the bottom of the lifting rod is connected to the top of the connecting plate.

[0016] By adopting the above technical solution, the staff starts the second cylinder. The piston rod of the second cylinder rises and falls, which drives the lifting rod to rise and fall synchronously, thereby driving the connecting plate to move synchronously. This causes the rotating shaft to rise and fall to the desired depth, so that the transmission groove on the rotating shaft contacts the transmission block, thereby driving the connecting rod and the flip plate to rotate synchronously.

[0017] Preferably, the support plate is provided with a horizontal plate and a buffer. The horizontal plate is horizontally arranged and located on the support plate. The horizontal plate has a vertical groove through which the connecting rod can pass. The buffer is located on the horizontal plate and is used to contact the bottom of the rotating shaft and to buffer the rotating shaft.

[0018] By adopting the above technical solution, the horizontal plate supports the buffer component. When the shaft rises and falls, the bottom of the shaft contacts the buffer component, making it less likely for the shaft to rise and fall excessively, thus preventing damage to the transmission block and connecting rod and extending the service life of the transmission block and connecting rod.

[0019] Preferably, the buffer component includes a buffer plate and a spring. The buffer plate is vertically arranged, and its sidewall is connected to a support plate. The buffer plate has a buffer groove for the shaft to be raised and lowered. The spring is located at the bottom of the buffer plate, with one end connected to the buffer plate and the other end connected to a horizontal plate.

[0020] By adopting the above technical solution, when the rotating shaft is raised or lowered, the elastic potential energy of the spring reduces the collision damage between the rotating shaft and the buffer plate, thereby extending the service life of the transmission block and the connecting rod.

[0021] Preferably, the top of the buffer plate is provided with a flexible layer, the bottom of the flexible layer is connected to the buffer plate, and the top of the flexible layer is in contact with the bottom of the rotating shaft.

[0022] By adopting the above technical solution, the flexible layer contacts the bottom of the rotating shaft, further enabling the rotating shaft to buffer the buffer plate and extend the service life of the buffer plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. After the staff finishes printing on one side of the sock, the staff activates the second cylinder. The piston rod of the second cylinder extends and retracts, causing the lifting rod to rise and fall synchronously. This, in turn, causes the connecting plate, drive motor, and rotating shaft to rise and fall to the set height. The staff then activates the drive motor, causing the output shaft of the drive motor to rotate synchronously. This, in turn, causes the rotating shaft to rotate synchronously. Through the transmission groove and transmission block, the connecting rod rotates with the rotating shaft, causing the flip plate to rotate synchronously. The flip plate flips to the set angle, making it convenient to print on the other side of the sock. This eliminates the need for the staff to manually operate the flip plate, saving time and effort.

[0025] 2. When the flap is flipped to the set angle, the operator starts the second cylinder. The piston rod of the second cylinder extends and retracts, causing the limit rod to move synchronously until the side wall of the limit rod contacts the side wall of the limit groove, thereby limiting the connecting rod and then limiting the flap, improving the stability of the flap and making it less likely to rotate at will.

[0026] 3. The flexible layer buffers and limits the buffer plate, making it less likely for the rotating shaft to collide with the transmission block when the shaft is raised or lowered, thereby reducing collision damage between the rotating shaft and the transmission block and extending the service life of the buffer plate and the transmission block.

Detailed Implementation

[0032] The following combination Figures 2-4 This application will be described in further detail.

[0033] This application discloses a locking mechanism for a double-sided printing and flipping device for socks.

[0034] Reference Figure 2 and Figure 3 A locking mechanism for a double-sided printing and flipping device for socks includes a conveyor belt 11, a support plate 12, and a flip plate 13 located on a frame 1. The conveyor belt 11 is located on and fixedly connected to the frame 1. The vertically arranged support plate 12 is T-shaped and located on the conveyor belt 11, in contact with the conveyor belt 11. The support plate 12 moves with the conveyor belt 11, and the conveyor belt 11 transports the support plate 12 to a set position. The vertically arranged flip plate 13 is located at the bottom of the support plate 12 and is rotatably connected to a connecting plate 2. The socks are fitted onto the flip plate 13.

[0035] Reference Figure 2 and Figure 3 Two horizontal plates 14 are installed on the side wall of the support plate 12. The two horizontal plates 14 are distributed vertically, and the side wall of each horizontal plate 14 is fixedly connected to the side wall of the support plate 12. The frame 1 is equipped with a connecting plate 2 for driving the flip plate 13 to rotate, a drive motor 21, a transmission component 3, and a limiting mechanism 5. The transmission component 3 includes a rotating shaft 31 and a transmission block 32, and the limiting mechanism 5 includes a connecting rod 51, a limiting rod 52, and a driving component.

[0036] A lifting component 6 is installed on the connecting plate 2. The lifting component 6 includes a second cylinder 61 and a lifting rod 62. The second cylinder 61 is located at the top of the conveyor belt 11. The cylinder body of the second cylinder 61 is fixedly connected to the frame 1. The piston rod of the second cylinder 61 is set vertically downward. The piston rod of the second cylinder 61 is coaxially fixedly connected to the lifting rod 62. The bottom of the vertically set lifting rod 62 is fixedly connected to the top of the connecting plate 2.

[0037] The connecting plate 2 is located on top of the support plate 12, and its sidewall is in contact with the sidewall of the frame 1. The drive motor 21 is located on the connecting plate 2 and is fixedly connected to it. The output shaft of the drive motor 21 passes through the connecting plate 2 and is coaxially fixedly connected to the rotating shaft 31. The vertically arranged rotating shaft 31 is located above the flip plate 13, and a transmission groove 41 is provided at the bottom of the rotating shaft 31. The vertically arranged transmission groove 41 is prismatic. The vertically arranged transmission block 32 is prismatic. The transmission block 32 is located at the bottom of the rotating shaft 31, and its top is used to contact the sidewall of the transmission groove 41. The bottom of the transmission block 32 is fixedly connected to the connecting rod 51. One end of the vertically arranged connecting rod 51 passes through the horizontal plate 14 and is fixedly connected to the top of the flip plate 13. Two limiting grooves 42 are provided on the sidewall of the connecting rod 51. The two limiting grooves 42 are evenly distributed along the circumference of the connecting rod 51, and the length direction of each limiting groove 42 is consistent with the radial direction of the connecting rod 51. The driving component includes a first cylinder 53, which is located on the side wall of the support plate 12. The cylinder body of the first cylinder 53 is fixedly connected to the support plate 12. The first cylinder 53 is in contact with the frame 1 and moves with the support plate 12. The piston rod of the first cylinder 53 passes through the support plate 12 and is coaxially fixedly connected to the limiting rod 52. The end of the horizontally arranged limiting rod 52 away from the first cylinder 53 is used to contact the side wall of the limiting groove 42.

[0038] After the printing on one side of the sock on the flip plate 13 is completed, the staff will use the conveyor belt 11 to transport the support plate 12 and the flip plate 13 to the bottom of the connecting plate 2. At this time, the staff will start the second cylinder 61. The piston rod of the second cylinder 61 will rise and fall, driving the lifting rod 62 to rise and fall synchronously, so that the connecting plate 2, the drive motor 21 and the rotating shaft 31 will rise and fall synchronously until the lifting shaft of the rotating shaft 31 reaches the set height. The operator then starts the drive motor 21. The output shaft of the drive motor 21 rotates, causing the rotating shaft 31 to rotate synchronously. Through the transmission groove 41 and the transmission block 32, the connecting rod 51 rotates with the rotating shaft 31, thereby causing the socks on the flip plate 13 to rotate synchronously until the socks on the flip plate 13 rotate to the set angle. At this time, the operator starts the first cylinder 53. The piston rod of the first cylinder 53 extends and retracts, causing the limiting rod 52 to move synchronously until the side wall of the limiting rod 52 contacts the side wall of the limiting groove 42. The operator then starts the second cylinder 61. The piston rod of the second cylinder 61 moves vertically upward, thereby causing the lifting rod 62, the connecting plate 2, the drive motor 21, and the rotating shaft 31 to move synchronously vertically upward, causing the transmission groove 41 on the rotating shaft 31 to disengage from the transmission block 32, thereby transferring the flip plate 13 and the socks to the set position, so that the other side of the socks can be printed. The limiting rod 52 limits the connecting rod 51, thereby improving the stability of the connecting rod 51 and the flip plate 13. This makes it easier for staff to print on the flipped socks, thus improving the printing quality and saving time and effort, reducing the workload of staff.

[0039] Reference Figure 3 and Figure 4 A horizontal plate 14 and a buffer component 7 are installed on the support plate 12. There are two horizontal plates 14, which are distributed vertically. The side wall of each horizontally arranged horizontal plate 14 is fixedly connected to the side wall of the support plate 12. Each horizontal plate 14 has a vertical groove 43 through which the connecting rod 51 passes. The vertical groove 43 penetrates the horizontal plate 14 vertically. The buffer component 7 includes a buffer plate 71 and a spring 72. The vertically arranged buffer plate 71 is located at the top of the horizontal plate 14, and the side wall of the buffer plate 71 is hinged to the side wall of the support plate 12. The top of the buffer plate 71 contacts the bottom of the transmission block 32, thereby supporting the transmission block 32, the connecting rod 51, and the flip plate 13. A buffer plate 71 has a buffer groove 44 for raising and lowering the rotating shaft 31. The buffer groove 44 extends vertically through the buffer plate 71. A flexible layer 8 made of rubber is installed on the top of the buffer plate 71. The bottom of the flexible layer 8 is bonded to the top of the buffer plate 71, and the top of the flexible layer 8 is in contact with the bottom of the rotating shaft 31. A vertically arranged spring 72 is located at the bottom of the buffer plate 71. One end of the spring 72 is in contact with the bottom of the buffer plate 71, and the other end of the spring 72 is fixedly connected to the top of the horizontal plate 14.

[0040] When the piston rod of the second cylinder 61 rises and falls, it drives the rotating shaft 31 to rise and fall synchronously. When the rotating shaft 31 rises and falls to the set height, the bottom of the rotating shaft 31 contacts the buffer plate 71, and the transmission groove 41 on the rotating shaft 31 contacts the transmission block 32. Through the elastic potential energy of the spring 72, the collision damage between the rotating shaft 31 and the buffer plate 71 and the transmission block 32 is reduced, and the service life of the buffer plate 71 and the transmission block 32 is extended. At the same time, the buffer plate 71 supports the transmission block 32. When the rotating shaft 31 contacts the transmission block 32 and collides, the connecting rod 51 moves in the vertical direction and rotates with the transmission block 32 and the rotating shaft 31 until the connecting rod 51 rises and falls to the set height and rotates to the set angle. Then, the limiting rod 52 contacts the limiting groove 42, thereby limiting the connection rod 51.

[0041] The locking mechanism of the double-sided printing flipping device for socks according to this application embodiment operates as follows: A worker places a sock onto the flip plate 13. After printing on one side of the sock, the worker starts the conveyor belt 11, causing the support plate 12 and the flip plate 13 to be transported to the bottom of the second cylinder 61. The worker then starts the second cylinder 61, causing the piston rod of the second cylinder 61 to rise and fall, which in turn causes the lifting rod 62 to rise and fall synchronously. This, in turn, causes the connecting plate 2, the drive motor 21, and the rotating shaft 31 to rise and fall synchronously. When the connecting plate 2 rises and falls to the set height, the worker starts the drive motor 21, causing the drive motor 21 to... The rotation of the output shaft drives the rotating shaft 31 to rotate synchronously. Through the transmission groove 41 and the transmission block 32, the connecting rod 51 rotates with the rotating shaft 31, thereby driving the flip plate 13 to rotate synchronously. At this time, the staff starts the first cylinder 53. The piston rod of the first cylinder 53 extends and retracts, driving the limiting rod 52 to move synchronously until the side wall of the limiting rod 52 contacts the side wall of the limiting groove 42, thereby limiting the connecting rod 51 and improving the stability of the connecting rod 51 and the flip plate 13. This makes it convenient for the staff to print on the other side of the sock without the need for manual operation, saving time and effort and reducing the workload of the staff.

[0042] When the limiting rod 52 contacts the limiting groove 42, the operator starts the second cylinder 61. The piston rod of the second cylinder 61 moves upward, thereby driving the lifting rod 62 to move synchronously, which in turn drives the connecting plate 2, the drive motor 21 and the rotating shaft 31 to move synchronously, thereby disengaging the rotating shaft 31 from the transmission block 32, so that the operator can easily transfer the flip plate 13 to the set position for printing.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
