Description

Technical Field

[0001] This utility model relates to the field of air-float transmission type pen refill conveyor line. Background Technology

[0002] In the pen refill production process, the refills undergo ink filling and assembly sequentially via a refill conveyor line. Traditional refill conveyor lines typically use methods such as conveyor belts and roller conveyors. These conveying components generate friction on the surface of the refills during contact and transport. This friction, especially under long-term, large-volume continuous conveying operations, can easily lead to scratches on the surface of the refills.

[0003] For high-end pens, the pen holder and refills are often more refined and sophisticated in terms of design, material selection, and manufacturing processes. Their market value and competitiveness largely depend on the overall aesthetic appeal and high-quality appearance. Scratches on the refill surface not only directly affect the product's visual appeal and lower its perceived quality in the consumer's mind, but may also weaken its competitiveness in the high-end market, hindering the production and sales of high-end pens. Therefore, polishing the refills is necessary, impacting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an air-float transmission type pen refill conveyor line. This conveyor line realizes the step-by-step movement of the pen refill through the inner support seat. At the same time, the airflow output from the grooves on the inner and outer support seats lifts the pen refill and separates it from the grooves, thereby reducing the probability of the pen refill being scratched and saving the subsequent grinding and polishing steps required for the pen refill.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] An air-floating transmission type pen refill conveyor line includes a frame, an inner support base, and an outer support base. The inner support base is driven to move up and down on the frame by a parallelogram mechanism. The outer support base is fixed on the frame. There are two outer support bases, which are symmetrically arranged on the front and back sides of the inner support base. Both the inner and outer support bases have several grooves at equal intervals on the left and right. Air holes are provided in the grooves, and airflow is output upward through the air holes. The pen refill is placed in the groove.

[0007] In the above technical solution, preferably, the parallelogram mechanism includes a base, connecting rods, and a motor. The inner support is fixedly installed on the upper end of the base. Four connecting rods are provided and symmetrically arranged on the front and rear sides of the base. The four connecting rods are arranged in parallel. The lower end of the connecting rod is rotatably mounted on the frame. The upper end of the connecting rod is hinged to the bottom end of the base. The motor drives the lower end of a connecting rod located on the rear side of the base to rotate through a gear chain transmission mechanism.

[0008] In the above technical solution, preferably, the lower ends of the two connecting rods located on the front side of the base are coaxially fixed with gears, and chains are sleeved on the two gears.

[0009] In the above technical solution, preferably, two inner support seats are provided and are symmetrically arranged at the front and rear ends of the base.

[0010] In the above technical solution, preferably, the tank is V-shaped, and multiple air holes are opened on the inclined surface of the tank and the air holes are perpendicular to the inclined surface of the tank.

[0011] In the above technical solution, preferably, the inclined surface of the trough is provided with a buffer pad, and the buffer pad is provided with through holes that communicate with the air holes and are in the same direction.

[0012] Compared with the prior art, this utility model has the following advantages and effects:

[0013] This invention places the pen refill in grooves on two outer support seats in a front-to-back direction. A parallelogram mechanism drives the inner support seat to rotate while remaining horizontal. The grooves on the inner support seat lift the pen refill and move it to a groove on the outer support seat adjacent to its original position. With the continuous operation of the inner support seat, the pen refill moves sequentially in the same direction within the grooves on the outer support seats, thus achieving pen refill delivery. Since both the inner and outer support seat grooves can output airflow upwards, the buoyancy of the airflow can be adjusted to precisely separate the pen refill from the grooves. Therefore, during pen refill delivery, the pen refill never comes into contact with the grooves of the inner and outer support seats, reducing the probability of scratches, ensuring the aesthetic appearance of the pen refill, saving the need for subsequent grinding and polishing steps, and improving pen refill production efficiency.

[0019] The components include: frame 1, inner support base 2, outer support base 3, parallelogram mechanism 4, base 41, connecting rod 42, motor 43, gear 44, chain 45, groove 5, air hole 51, buffer pad 52, and pen refill 6. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figures 1-5 This embodiment describes an air-float transmission type pen refill conveyor line, including a frame 1, an inner support 2, and an outer support 3. The inner support 2 is driven to move up and down on the frame 1 by a parallelogram mechanism 4. The outer support 3 is fixed on the frame 1. There are two outer support 3s, which are symmetrically arranged on the front and back sides of the inner support 2. Both the inner support 2 and the outer support 3 are provided with several grooves 5 at equal intervals on the left and right. Air holes 51 are provided in the grooves 5, and airflow is output upward through the air holes 51. The pen refill 6 is adapted to be placed in the groove 5.

[0022] This invention places the pen refill 6 in the grooves 5 of two outer support seats 3 in a front-to-back direction. A parallelogram mechanism 4 drives the inner support seat 2 to rotate while maintaining its horizontal position. The grooves 5 on the inner support seat 2 lift the pen refill 6 and move it. The pen refill 6 moves to the groove 5 on the outer support seat 3 adjacent to its original position. With the continuous operation of the inner support seat 2, the pen refill 6 moves sequentially in the same direction within the grooves 5 on the outer support seat 3, thus achieving the conveying of the pen refill 6. Since both the grooves 5 of the inner support seat 2 and the grooves 5 of the outer support seat 3 can output airflow upwards, the buoyancy of the airflow can be adjusted to just separate the pen refill 6 from the grooves 5. Therefore, during the conveying process, the pen refill 6 never comes into contact with the grooves 5 of the inner and outer support seats 2 and 3, thereby reducing the probability of the pen refill 6 being scratched, ensuring the aesthetic appearance of the pen refill 6, saving the subsequent grinding and polishing steps, and improving the production efficiency of the pen refill 6.

[0023] See Figure 2 , Figure 3The parallelogram mechanism 4 includes a base 41, connecting rods 42, and a motor 43. The inner support 2 is fixedly installed on the upper end of the base 41. Four connecting rods 42 are provided and symmetrically arranged on the front and rear sides of the base 41. The four connecting rods 42 are arranged in parallel. The lower end of the connecting rod 42 is rotatably mounted on the frame 1. The upper end of the connecting rod 42 is hinged to the bottom end of the base 41. The motor 43 drives the lower end of one of the connecting rods 42 located on the rear side of the base 41 to rotate through a gear 44 and chain 45 transmission mechanism.

[0024] The lower end of the connecting rod 42 is driven by the motor 43 to rotate relative to the frame 1. Since the connecting rod 42, the base 41, and the frame 1 form a parallelogram mechanism 4, the base 41 and the inner support 2 can rotate while remaining horizontal. This allows the inner support 2 to lift the pen refill 6 from the outer support 3 and place it on the outer support 3, enabling the pen refill 6 to move sequentially within the groove 5 on the outer support 3, thus achieving the effect of conveying the pen refill 6. This mechanism has a simple structure. By enabling the pen refill 6 to move in a step-like manner, it can be coordinated with the ink filling, assembly, and testing stations of the pen refill 6, facilitating the mass production of the pen refill 6.

[0025] See Figure 2 The lower ends of the two connecting rods 42 located on the front side of the base 41 are coaxially fixed with gears 44, and chains 45 are sleeved on the two gears 44.

[0026] The gear 44 and chain 45 transmission mechanism at this position enable the connecting rods 42 at both ends of the base 41 to rotate simultaneously under the driving force, thereby improving the stability of the base 41's movement, reducing the degree of shaking during the movement of the base 41, and reducing the risk of the pen refill 6 colliding with the inner support seat 2 and the outer support seat 3.

[0027] See Figure 3 The inner support base 2 is provided in two parts and is symmetrically arranged at the front and rear ends of the base 41.

[0028] The two inner support seats 2 ensure that a symmetrical and uniform buoyancy force is applied to the pen refill 6, while reducing the volume and mass of the inner support seats 2. This reduces the burden on the motor 43, thereby reducing power consumption, and also improves the stability of the movement of the base 41 and the inner support seats 2. In addition, in the event of insufficient air supply, the contact area between the pen refill 6 and the inner support seats 2 can be reduced, thus reducing wear on the pen refill 6.

[0029] See Figure 4 , Figure 5 The trough 5 is V-shaped, and multiple air holes 51 are provided on the inclined surface of the trough 5, with the air holes 51 perpendicular to the inclined surface of the trough 5.

[0030] The V-shaped groove 5 and the air vent 51 perpendicular to the inclined surface of the groove 5 ensure that the airflow output from the air vent 51 is perpendicular to the inclined surface of the groove 5. When the pen refill 6 is placed in the groove 5, the airflow acts on the pen refill 6, driving it away from the inclined surface of the groove 5, while simultaneously subjecting the pen refill 6 to uniform and symmetrical buoyancy from both sides, thus improving the stability of the pen refill 6 placed in the groove 5. At the same time, when the inner support 2 moves, the oblique airflow generates a thrust on the pen refill 6, enabling the pen refill 6 to quickly respond and follow the movement of the inner support 2, reducing the risk of collision between the pen refill 6 and the inner support 2.

[0031] See Figure 4 , Figure 5 The inclined surface of the groove 5 is provided with a buffer pad 52, and the buffer pad 52 is provided with a through hole that communicates with the air hole 51 and is in the same direction.

[0032] The buffer pad 52 can protect the pen tip 6 when it accidentally collides with the groove 5, and prevent the pen tip 6 from being scratched by collision with the hard inner support 2 and outer support 3.
