Abstract
Description
Technical Field
[0001] The utility model relates to the field of automatic penholder paint lines, in particular to a quick-drying automatic paint line. Background Art
[0002] While automation improves efficiency for slender, tubular pen barrels, it also presents a host of challenges. First, the hollow tubular design complicates positioning and clamping on the production line. Traditional fixtures struggle to ensure stability during the painting process, increasing the risk of shaking and shifting. Therefore, custom fixtures must be designed to accommodate the unique shape, which undoubtedly increases equipment complexity and manufacturing costs.
[0003] Secondly, transporting the pen barrels along the production line presents a significant challenge. Their tubular shape can easily cause them to roll or tilt, affecting the uniformity and quality of the paint application. Existing transport equipment often struggles to perfectly match the shape of the pen barrels, making position and angle control during transport difficult.
[0004] Furthermore, due to the limited shape of the pen holder, the spray gun cannot precisely control the direction and distance of the paint, resulting in uneven paint distribution and affecting the product's appearance. Furthermore, the limited positioning and movement can cause overspray or spillage, resulting in unnecessary waste. Utility Model Content
[0005] The main purpose of the utility model is to provide a quick-drying paint automatic line, which can effectively solve the problems raised in the background technology.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A quick-drying paint automatic line includes a production line body, a tunnel-type drying device, a hot air duct, a transmission chain, a paint spraying box, a feeding device, a transmission device, a movable frame, and a paint spraying head. The feeding device is located at one end of the production line body. The paint spraying box and the tunnel-type drying device are arranged on the production line body in sequence from one end to the other. The hot air duct is installed on the tunnel-type drying device. The transmission chain is installed on the production line body. The paint spraying head is installed on the transmission device via the movable frame. The transmission device is installed on the paint spraying box. The quick-drying paint spraying operation is achieved by the paint spraying head, and the drying operation is achieved by using the tunnel-type drying device.
[0008] The transmission chain is connected to two transmission belts, and a gap is provided between the two transmission belts for discharging excess paint;
[0009] Multiple bases are installed on each of the transmission belts, and a rotating base is installed on the upper end of each base. An inner cylinder is installed on the upper end of the rotating base. An outer cylinder is sleeved on the outer side of the inner cylinder, and a plurality of elastic strips are provided on the side wall of the outer cylinder. The pen barrel opening is inserted into the outer cylinder and then the pen barrel is tightly fixed by the elastic strips, or the pen barrel is inserted into the inner cylinder and then the pen barrel is connected by the rubber strip.
[0010] As a preferred solution of the present invention, a plurality of bases are equidistantly distributed on the transmission belt, a T-shaped key is provided at the center of the upper end of the base, and a T-shaped slot adapted to the T-shaped key is provided at the lower end of the rotating seat, and the rotating seat and the base are limitedly connected by the T-shaped key and the T-shaped slot;

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In this utility model, the penholder positioning device ensures precise positioning of the penholder on the production line through the tight cooperation of the T-key and T-slot of the base and swivel seat, thereby ensuring uniform and accurate painting. The vertical grooves in the inner barrel sidewall and the rubber strips bonded to the inner wall provide soft support and fixation for the penholder. The elastic and rubber strips in the outer barrel ensure a firm hold during transport, effectively preventing the penholder from shaking or falling off during painting and drying.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1 - Figure 4 The figure shows an efficient, fast-drying paint automated production line system that integrates multiple key components to achieve a smooth paint spraying and rapid drying process. Specifically, the system consists of a production line 1 as the core support structure, with a feeder 6, a paint spraying box 5, a tunnel drying unit 2, and a series of auxiliary equipment arranged along its length.
[0027] At the starting point of the production line 1, a feeder 6 precisely feeds the workpieces to be processed. The workpieces then enter the paint booth 5, which houses advanced painting equipment. A paint spray head 9 is mounted on a transmission device 7 via a movable frame 8. This transmission device 7 is securely attached to the top or side of the paint booth 5, ensuring that the paint spray head 9 can flexibly move along a pre-set trajectory, applying paint evenly and efficiently to the workpiece surface. During the painting process, the operation of the paint spray head 9 is precisely controlled by an intelligent control system to achieve high-quality paint results.
[0028] To further improve drying efficiency, the system utilizes a tunnel drying device 2. This device, located along the length of the production line 1, incorporates integrated hot air ducts 3, which circulate hot air to provide a uniform drying environment for the painted workpieces. The optimized layout of the hot air ducts 3 ensures efficient heat transfer and utilization, shortening drying time and improving production efficiency.
[0029] The transmission chain 4 plays a crucial role in transporting workpieces. It runs the entire length of the production line 1 and is connected to two parallel transmission belts 10. A gap is cleverly designed between these two belts 10 to allow excess paint to be drained during transport, keeping the production line clean and running smoothly.
[0030] To accommodate workpieces of varying sizes and shapes, the transmission belt 10 is equipped with multiple bases 11 spaced evenly apart. Each base 11 features a T-shaped key that mates tightly with the T-slot at the bottom of the rotating base 12, forming a secure, position-limiting connection. The rotating base 12 is integrally designed with an inner cylinder 13, which features vertical grooves in its sidewalls and a rubber strip bonded to the inner wall to provide soft support and secure fit. When a workpiece (such as a pen) is inserted into the inner cylinder 13, the rubber strip adheres tightly to the outer wall, preventing it from shaking or falling out.
[0031] In addition, the design of the outer cylinder 14 is also quite ingenious. It is installed on the outside of the inner cylinder 13, and the side wall is provided with multiple "C"-shaped cross-section elastic strips 15. The surface of these elastic strips 15 is also bonded with rubber strips to increase friction and adaptability. After being fixed to the outer cylinder 14 by bolts, they can adjust their position as the inner diameter of the workpiece changes, ensuring that the workpiece is firmly fixed. At the same time, the spiral groove on the inner wall of the outer cylinder 14 cooperates with the vertical groove of the inner cylinder 13, and the rotational connection between the two is achieved by a limit block, so that the workpiece can maintain a stable posture during the painting and drying process.
[0032] This quick-drying paint automatic line achieves efficient and precise spraying and rapid drying of workpieces through ingenious design and efficient component configuration.
[0033] Instructions: Place the pen holder to be sprayed onto the feed mechanism 6. The feed mechanism 6 activates, precisely feeding the pen holder into the starting point of the production line 1. Once the pen holder enters the paint spraying chamber 5, the paint spray head 9 begins operation under the precise control of the intelligent control system. Driven by the transmission device 7 via the movable frame 8, the paint spray head 9 flexibly moves along a preset trajectory, applying paint evenly and efficiently to the pen holder surface. During the painting process, the intelligent control system adjusts parameters such as the spray speed and spray volume of the paint spray head 9 in real time to ensure a high-quality painting result.
[0034] After painting is completed, the pen holder continues to be transmitted along the transmission chain 4 and enters the preparation stage before drying. There is a gap between the two parallel transmission belts 10 laid on the transmission chain 4 to discharge excess paint in time during the transmission process and keep the production line clean and smooth.
[0035] After the pen holders enter the tunnel drying device 2, hot air ducts 3 begin circulating hot air. This hot air flows through the tunnel drying device 2, providing a uniform drying environment for the painted pen holders. The optimized layout of the hot air ducts 3 ensures efficient heat transfer and utilization, shortening drying time and improving production efficiency.
[0036] During the entire painting and drying process, the pen holder is firmly fixed in the base 11 on the transmission belt 10. The base 11 is tightly matched with the T-slot of the rotating seat 12 through the T-key to form a stable limiting connection. The rotating seat 12 and the inner cylinder 13 are designed as one piece, and the vertical grooves on the side walls of the inner cylinder 13 and the rubber strips bonded to the inner wall provide soft support and fixing effects for the pen holder. The outer cylinder 14 is sleeved on the outside of the inner cylinder 13, and through the cooperation of the elastic strip 15 and the rubber strip, the position is adjusted as the inner diameter of the pen holder changes, ensuring that the pen holder is firmly pressed and fixed. At the same time, the outer cylinder 14 and the inner cylinder 13 are rotatably connected through the limiting blocks of the spiral groove body and the vertical groove, so that the pen holder maintains a stable posture during the painting and drying process.
[0037] After drying, the pen barrels are transported along the transmission chain 4 to the discharge area. There, workers or automated equipment remove the pen barrels from the production line for subsequent quality inspection and packaging. The automatic pen barrel quick-drying paint line achieves efficient and precise spraying and rapid drying of pen barrels, improving production efficiency and product quality.
