Description

Technical Field

[0001] This utility model relates to the field of pen manufacturing equipment technology, specifically to an assembly machine for producing pen refills. Background Technology

[0002] Gel pens are a novel writing tool that is currently popular internationally. They combine the advantages of fountain pens and ballpoint pens, offering a comfortable writing experience. The ink has lower viscosity and contains added lubricating substances, making it smoother than ordinary oil-based ballpoint pens. It is an upgraded replacement for oil-based ballpoint pens.

[0003] Utility model CN213768038U discloses an automatic pen refill and nib assembly machine, relating to the field of pen manufacturing equipment technology. It includes a base, with lifting cylinders fixedly installed at the four corners of the top of the base. Support seats are fixedly installed at the output ends of the four sets of lifting cylinders. This utility model uses a motor to drive a rotating disk, inside which multiple sets of assembly cylinders are evenly arranged. Each assembly cylinder's output end is fixedly equipped with a suction cup and a clamping head.

[0004] The aforementioned application document describes a pen refill that is gripped and held by a clamping head on a feeding rack and then rotated under a motor. After rotation, an assembly cylinder pushes the clamping head to assemble the pen refill with the pen refill on the assembly line. The assembly process is rather cumbersome, and the pen refill is prone to shifting during the assembly process. Utility Model Content

[0005] This invention proposes an assembly machine for producing pen refills, which solves the problem of pen refills easily shifting during the assembly process in related technologies.

[0006] The technical solution of this utility model is as follows: An assembly machine for producing pen refills is proposed, comprising a base, an ink injection device and a rotary motor mounted on the top of the base, a rotating disk fixedly connected to the rotary motor via its output shaft, and a clamping assembly mechanism mounted on the surface of the rotating disk; the clamping assembly mechanism includes an electric push rod fixedly mounted on the surface of the rotating disk, a movable seat fixedly connected to the output end of the electric push rod, a groove formed at the end of the movable seat away from the electric push rod, a slider slidably connected inside the groove, a clamping plate fixedly connected to the end of the slider away from the groove, a fixed plate fixedly connected to the end of the movable seat away from the electric push rod, a threaded rod rotatably connected to the top of the fixed plate, a clamping motor fixedly mounted on the top of the movable seat, a clamping groove formed on the top of the clamping plate, a lifting plate fixedly connected to the end of the clamping plate near the movable seat, and a clamping mechanism mounted inside the clamping groove.

[0007] Optionally, the output shaft of the clamping motor is fixedly connected to the top of the threaded rod, and the lifting plate is threadedly connected to the threaded rod through the built-in thread. Turning on the clamping motor can drive the threaded rod to rotate, and the rotation of the threaded rod will drive the two sets of lifting plates on it to move closer or further apart through the engagement of the threads.

[0008] Optionally, the clamping groove is semi-cylindrical in shape, and the pen tube is clamped through the clamping groove when the two sets of clamping plates move close to each other.

[0009] Optionally, the top height of the rotating disk is at the same level as the top height of the ink filling device, and when the rotating disk rotates, it will drive the pen tube held in the disk to rotate to the ink filling device.

[0010] Optionally, the clamping mechanism includes a clamping airbag and an air chamber. The clamping airbag is fixedly connected inside the clamping groove, and the air chamber is fixedly connected inside the clamping plate. A piston rod is slidably connected to the piston inside the air chamber. A pressure plate is fixedly connected to the end of the piston rod away from the air chamber. A return spring is sleeved on the surface of the piston rod. An air tube is passed through and fixedly connected to the side of the air chamber.

[0011] Optionally, the air tube is L-shaped, and the end of the air tube away from the air chamber passes through and is fixedly connected to the clamping airbag. When the piston rod moves downward, it will compress the air in the air chamber, allowing the air to enter the clamping airbag through the air tube.

[0012] Optionally, the clamping airbag is arc-shaped and initially in a contracted state, and can clamp the pen tube when it expands.

[0013] Optionally, in the initial state, the two ends of the return spring are in contact with the air chamber and the pressure plate, respectively. When the pressure plate moves downward, it causes the piston rod to move downward, which in turn causes the return spring to be gradually compressed.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting up a clamping assembly mechanism, when the clamping motor is turned on and drives the threaded rod to rotate, the corresponding two sets of clamping plates will move closer together through the cooperation of components such as the sliding groove, sliding groove, and lifting plate. At this time, the pen tube can be clamped through the clamping groove. Then, the rotating motor can drive the rotating disk to rotate, and with the help of the electric push rod, the clamped pen tube can be moved to the ink filling device for ink filling.

[0016] 2. In this utility model, a clamping mechanism is provided so that when the two sets of clamping plates move close together to clamp the pen tube, the clamping airbag will expand due to the cooperation of components such as the air chamber, pressure plate, and piston rod. At this time, the expanded clamping airbag and the clamping groove can ensure that the pen tube is clamped firmly and prevent the pen tube from shifting during the assembly process.

[0029] Example 1

[0030] Reference Figures 1-6This is the first embodiment of the present invention, which proposes an assembly machine for producing pen refills. It includes a base 1, with an ink-filling device 2 and a rotary motor 3 mounted on the top of the base 1. The rotary motor 3 is fixedly connected to a rotating disk 4 via its output shaft. The top height of the rotating disk 4 is at the same level as the top height of the ink-filling device 2. When the rotating disk 4 rotates, it drives the pen tube it is holding to rotate to the ink-filling device 2. A clamping assembly mechanism 5 is provided on the surface of the rotating disk 4. The clamping assembly mechanism 5 includes an electric push rod 51, which is fixedly mounted on the surface of the rotating disk 4. A movable seat 52 is fixedly connected to the output end of the electric push rod 51. A groove 53 is provided at the end of the movable seat 52 away from the electric push rod 51. A slider 54 is slidably connected inside the groove 53. A clamping plate 55 is fixedly connected to the end of the slider 54 away from the groove 53. A fixed plate 56 is fixedly connected to the end of the moving seat 52 away from the electric push rod 51. A threaded rod 57 is rotatably connected to the top of the fixed plate 56. A clamping motor 58 is fixedly installed on the top of the moving seat 52. The output shaft of the clamping motor 58 is fixedly connected to the top of the threaded rod 57. The lifting plate 510 is threadedly connected to the threaded rod 57 through an internal thread. Turning on the clamping motor 58 can drive the threaded rod 57 to rotate. The rotation of the threaded rod 57 will drive the two sets of lifting plates 510 on it to move closer or further apart through the engagement of the threads. A clamping groove 59 is provided on the top of the clamping plate 55. The clamping groove 59 is semi-cylindrical in shape. When the two sets of clamping plates 55 move closer together, they will clamp the pen tube through the clamping groove 59. A lifting plate 510 is fixedly connected to the end of the clamping plate 55 near the moving seat 52. A clamping mechanism 6 is provided inside the clamping groove 59.

[0031] In this embodiment, when assembling the pen refill, the pen tube is placed between the two sets of clamping plates 55. The rotary motor 3 is turned on, and the rotary motor 3 drives the threaded rod 57 to rotate through its output shaft. The rotation of the threaded rod 57 will cause the two sets of lifting plates 510 on it to move closer together through the engagement of the threads. When the two sets of clamping plates 55 move closer together, they will clamp the pen tube through the clamping groove 59, thereby achieving the effect of clamping multiple pen tubes and preventing the pen tubes from shifting during subsequent assembly. Then, the rotary motor 3 is turned on to drive the rotating disk 4 to rotate, and at the same time, the electric push rod 51 is turned on to drive the moving seat 52 to move, so that the clamped pen tubes are moved to the ink filling device 2 for ink filling. This completes the assembly work. The overall operation is simple and can improve the efficiency of assembling large batches of pen tubes.

[0032] Example 2

[0033] Reference Figures 1-6This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the clamping mechanism 6 includes a clamping airbag 61 and an air chamber 62. The clamping airbag 61 is fixedly connected inside the clamping groove 59, and the air chamber 62 is fixedly connected inside the clamping plate 55. A piston rod 63 is slidably connected to the piston inside the air chamber 62. A pressure plate 64 is fixedly connected to the end of the piston rod 63 away from the air chamber 62. A return spring 65 is sleeved on the surface of the piston rod 63. Initially, both ends of the return spring 65 abut against the air chamber 62 and the pressure plate 64, respectively. When the pressure plate 64 moves downward, it causes the piston rod 63 to move downward, which in turn causes the return spring 65 to be gradually compressed. An air tube 66 is fixedly connected through the side of the air chamber 62. The air tube 66 is L-shaped, and the end of the air tube 66 away from the air chamber 62 is fixedly connected through the clamping airbag 61. When the piston rod 63 moves downward, it will squeeze the air in the air chamber 62, so that the air enters the clamping airbag 61 through the air tube 66. The clamping airbag 61 is arc-shaped, and the clamping airbag 61 is initially in a contracted state. When the clamping airbag 61 expands, it can clamp the pen tube.

[0034] Compared to Embodiment 1, further, when the two sets of clamping plates 55 move closer together and clamp the pen tube through the clamping groove 59, the pressure plate 64 will be squeezed, causing the piston rod 63 to move into the air chamber 62. The return spring 65 is gradually compressed, and the movement of the piston rod 63 into the air chamber 62 will squeeze the air in the air chamber 62, causing it to enter the clamping airbag 61 through the air pipe 66. At this time, the clamping airbag 61 expands to ensure that the pen tube is clamped. When the two sets of clamping plates 55 move away from each other and separate, the return spring 65 rebounds, causing the pressure plate 64 and the piston rod 63 to return to their original positions. At this time, a negative pressure is formed in the air chamber 62, which will re-draw back the air pressure in the clamping airbag 61. The clamping airbag 61 re-contracts, making it easier to remove the pen tube. By using the clamping airbag 61 in conjunction with the clamping groove 59, the pen tube can be firmly clamped, preventing the pen tube from shifting during assembly.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
