Abstract
Description
Technical Field
[0001] This utility model belongs to the field of printing equipment technology, and in particular relates to a thermal paper label production equipment for preventing printed labels from shifting. Background Technology
[0002] Thermal paper label production equipment refers to equipment that uses thermal technology to print thermal paper together with thermal ribbons. It is mainly used to produce thermal label paper of various sizes and shapes.
[0003] According to a public disclosure (CN 219338959 U), a label production device for preventing label printing misalignment includes a mounting base. The top of the mounting base is disposed on an unwinding assembly. A left label printing machine body and a right label printing machine body are fixedly mounted on the top of the mounting base. The top of the mounting base also includes a drying assembly to facilitate drying after label printing and a cooling assembly to prevent misalignment of the label paper. The dried label paper enters the cooling assembly for cooling, and after cooling, the label paper enters the right label printing machine body for reprinting. This device effectively prevents misalignment of the printing position of the next color due to increased paper temperature and deformation. It avoids imperfect label patterns caused by misalignment, prevents defective products due to severe misalignment, and avoids the situation where misalignment is more pronounced in labels with more colors.
[0004] However, in the above application, the cooperation of components such as the unwinding assembly, the label printing machine body, the right label printing machine body, the drying assembly, and the cooling assembly makes it difficult to clamp and limit the label. This causes the label to move during the printing process, resulting in printing deviation, which reduces product quality and production efficiency and needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a thermal paper label production device that prevents printed labels from shifting. Through the interaction of a motor-driven mechanism with components such as a bidirectional threaded rod, threaded sleeves, a fixing plate, and a U-shaped clamping plate inside the clamping device, clockwise rotation of the bidirectional threaded rod causes relative movement of two threaded sleeves. This relative movement of the two threaded sleeves, in turn, causes relative movement of two fixing plates and two U-shaped clamping plates. The relative movement of the two U-shaped clamping plates clamps the label, achieving a clamping effect. This prevents the label from moving on the unwinding roller during printing, thus preventing label shifting and ensuring production efficiency and product quality, thereby solving existing problems.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a thermal paper label production equipment for preventing printed labels from shifting, comprising a support, a bracket fixedly connected to the bottom of the support, a printing device mounted on the top of the support, a triangular seat fixedly connected to the top of the support, an unwinding roller mounted on the side of the triangular seat, a support plate fixedly connected to the top of the support, a support roller mounted on the side of the support plate, and a clamping device mounted on the top of the support.
[0008] The clamping device includes a placement plate, the side of which is fixedly connected to the side of the support, a motor is fixedly connected to the top of the placement plate, a bidirectional threaded rod is fixedly connected to the output end of the motor, a threaded sleeve is threadedly connected to the circumferential surface of the bidirectional threaded rod, a fixing plate is fixedly connected to the side of the threaded sleeve, and a U-shaped clamping plate is fixedly connected to the top of the fixing plate.
[0009] Furthermore, a movable plate is fixedly connected to the top of the support, and a limiting groove is provided on the top of the movable plate to limit the movement trajectory of the threaded sleeve.
[0010] Furthermore, a limiting block is slidably connected inside the limiting groove. One end of the limiting block is slidably connected inside the limiting groove, and the other end of the limiting block is fixedly connected to the bottom of the threaded sleeve. A gear is fixedly connected to the side of the bidirectional threaded rod. The limiting block is used to restrict the movement trajectory of the threaded sleeve, and the gear is used to allow the rack to move.
[0011] Furthermore, the threaded sleeve, fixing plate, U-shaped clamping plate, and limiting block are arranged in two sets and are symmetrical to each other along the vertical central axis of the bidirectional threaded rod. The support plate is arranged in two sets and is symmetrical to each other along the vertical central axis of the support roller. The two sets of threaded sleeve, fixing plate, U-shaped clamping plate, and limiting block are arranged to clamp the label, and the two sets of support plates are arranged to support the support roller.
[0012] Furthermore, a limiting device is provided at the top of the support. The limiting device includes an L-shaped hydraulic cylinder. The bottom of the L-shaped hydraulic cylinder is fixedly connected to the top of the support. One end of the L-shaped hydraulic cylinder is slidably connected to a force rod via a piston. The other end of the L-shaped hydraulic cylinder is slidably connected to a hydraulic rod via another piston. A connecting plate is fixedly connected to the side of the hydraulic rod. An L-shaped connecting strip is fixedly connected to the side of the connecting plate. A first L-shaped limiting plate is fixedly connected to the top of the L-shaped connecting strip. The first L-shaped limiting plate is slidably connected to the circumferential surface of the support roller. The side of the first L-shaped limiting plate extends through the side of the support roller. The connecting plate is for connecting the L-shaped connecting strip. Movement of the connecting plate can cause movement of the L-shaped connecting strip. The L-shaped connecting strip is for causing movement of the first L-shaped limiting plate. The first L-shaped limiting plate is for limiting one side of the label, preventing the label from moving.
[0013] Furthermore, a rack is slidably connected to the top of the support, and a second L-shaped limiting plate is slidably connected to the circumferential surface of the support roller. The side of the second L-shaped limiting plate extends through the side of the support roller, and a handle is fixedly connected to the side of the second L-shaped limiting plate. A return spring is fixedly connected to the side of the L-shaped hydraulic cylinder, and one end of the return spring is fixedly connected to the side of the connecting plate. The rack is used to allow the force rod to retract when the rack moves. The second L-shaped limiting plate is used to limit the other side of the label. The handle is used to allow the second L-shaped limiting plate to move. The return spring is used to allow the hydraulic rod and the force rod to return to their original positions.
[0014] Furthermore, the circumferential surface of the gear meshes with the top of the rack, and the side of the force-bearing rod is located on the displacement trajectory of the side of the rack. This facilitates the rotation of the gear to move the rack, and the movement of the rack to retract the force-bearing rod and extend the hydraulic rod.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model utilizes a motor drive and internal components such as a bidirectional threaded rod, threaded sleeves, a fixing plate, and a U-shaped clamping plate to work together. The clockwise rotation of the bidirectional threaded rod causes the two threaded sleeves to move relative to each other. This relative movement of the two threaded sleeves, in turn, causes the two fixing plates and two U-shaped clamping plates to move relative to each other. The relative movement of the two U-shaped clamping plates clamps the label, achieving a clamping effect. This prevents the label from moving on the unwinding roller during the printing process, thus ensuring that the printed label does not shift and guaranteeing both production efficiency and product quality.
[0017] 2. This utility model utilizes a motor drive and internal components such as an L-shaped hydraulic cylinder, a first L-shaped limiting plate, a rack, and a second L-shaped limiting plate to work together. This achieves a situation where the forward movement of the hydraulic rod drives the connecting plate forward, which in turn drives the L-shaped connecting strip forward, which in turn drives the first L-shaped limiting plate forward. The forward movement of the first L-shaped limiting plate then limits the other side of the label, thus achieving a limiting effect. This limits the label on the support roller, preventing it from moving during printing, resulting in better printing quality and effectively avoiding label offset.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The circumferential surface of gear 810 meshes with the top of rack 97, and the side of force rod 92 is located on the displacement trajectory of the side of rack 97. This is beneficial for the rotation of gear 810 to make rack 97 move, and the movement of rack 97 can make force rod 92 retract and hydraulic rod 93 extend.
[0036] A specific application of this embodiment is as follows: When printing labels, in order to prevent the printed labels from shifting, the labels on the unwinding roller 5 need to be clamped. The user uses the clamping device 8. The user first places the label on the unwinding roller 5, then pulls out one end of the label, passes the pulled-out end through the printing equipment 3, and then places it on the support roller 7. The user holds the handle 99 and moves the second L-shaped limiting plate 98 backward through the handle 99. The backward movement of the second L-shaped limiting plate 98 can limit one side of the label. The user starts the motor 82, and the motor 82 drives the bidirectional threaded rod 83 to rotate clockwise. The clockwise rotation of the bidirectional threaded rod 83 will drive the two threaded sleeves 84 to move relative to each other. The relative movement of the two threaded sleeves 84 will drive the two limiting blocks 89 to move relative to each other in the limiting groove 88. The relative movement of the two threaded sleeves 84 will drive the two fixing plates 85 and the two U-shaped clamping plates 86 to move relative to each other. The relative movement of the two U-shaped clamping plates 86 will clamp the label.
[0037] When the label is on the support roller 7, it needs to be limited to prevent it from moving during printing for better results. The second L-shaped limiting plate 98 has already limited one side of the label; now, the other side needs to be limited. The operator uses the limiting device 9. While using the clamping device 8, the operator simultaneously uses the limiting device 9. The operator starts the motor 82, which drives the bidirectional threaded rod 83 to rotate clockwise. The clockwise rotation of the bidirectional threaded rod 83 drives the gear 810 to rotate clockwise. The gear 810 meshes with the rack 97. The clockwise rotation of the gear 810 causes the rack 97 to move to the left. The leftward movement of the rack 97... When the force rod 92 on the L-shaped hydraulic cylinder 91 is touched, the force rod 92 moves inside the L-shaped hydraulic cylinder 91. When the force rod 92 moves inside the L-shaped hydraulic cylinder 91, the hydraulic rod 93 will extend outward due to the force of the force rod 92 moving inside the L-shaped hydraulic cylinder 91, causing the hydraulic rod 93 to move forward. The forward movement of the hydraulic rod 93 will drive the connecting plate 94 to move forward, which in turn will drive the L-shaped connecting strip 95 to move forward. The forward movement of the L-shaped connecting strip 95 will drive the first L-shaped limiting plate 96 to move forward. The forward movement of the first L-shaped limiting plate 96 will limit the other side of the label, preventing the label from moving during printing and thus preventing printing offset.
