An automated secondary spraying mold production line with anti-sticking properties

Abstract

This utility model discloses an automated secondary oil spraying mold production line for preventing adhesion, belonging to the field of mold oil spraying technology. It includes two support frames. An oil storage tank is installed in the upper middle part of one support frame, and an oil pump is installed inside the oil storage tank. A rotating rod is rotatably connected inside the other support frame, and a row of oil nozzles is provided on the outer surface of the rotating rod. One end of each row of oil nozzles is equipped with a flexible hose, and the other end of each row of flexible hoses is connected to a first oil delivery pipe. One end of the first oil delivery pipe passes through the oil storage tank and is connected to the output end of the oil pump. The oil pump delivers oil from the oil storage tank to the first oil delivery pipe, and then discharges it through the oil nozzles. This achieves the effect of uniformly spraying oil onto the mold surface, avoiding excessively thick or thin oil films in certain areas, reducing the risk of adhesion. Furthermore, under constant pressure, the oil nozzles can atomize the oil into fine particles, enhancing adhesion and improving anti-sticking performance. It also reduces labor costs and human error.

Description

Technical Field

[0001] This utility model relates to the field of mold spraying technology, specifically to an automated secondary spraying mold production line that prevents sticking. Background Technology

[0002] In the candy production process, molds are key forming tools, such as steel molds. However, due to the tendency of sugar liquid to adhere to the surface of the mold during long-term use, product quality problems can occur. Therefore, it is necessary to spray an anti-stick agent, such as oil, onto the mold surface to prevent sticking. In traditional mold production lines, manual oil spraying is mostly used.

[0003] While traditional methods can spray oil onto molds, they suffer from uneven spraying results. Employees must perform repetitive spraying operations for extended periods at high intensity, increasing their workload and increasing the risk of operational errors or uneven spraying due to fatigue. As working hours increase, the consistency of manual spraying becomes difficult to guarantee, leading to a gradual decline in spraying quality and further exacerbating product quality fluctuations. This negatively impacts production stability and yield rates. Furthermore, inconsistent oil coverage across different areas of the mold surface results in some areas having excessively thin oil films with insufficient anti-stick properties. Consequently, sugar syrup adhesion can easily occur during subsequent molding processes, affecting the product's demolding performance. Utility Model Content

[0004] The purpose of this invention is to provide an automated secondary spraying mold production line that prevents sticking, in order to solve the problem of uneven spraying effect in current mold production lines on the market, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated secondary spraying mold production line for preventing adhesion, comprising two support frames, each of which is rotatably connected to a drive shaft, and a conveyor line between the two drive shafts. A drive motor is mounted at one end of one support frame, and the output end of the drive motor is connected to one drive shaft. An oil storage tank is mounted in the upper middle part of one support frame, and an oil pump is installed inside the oil storage tank. A rotating rod is rotatably connected inside one support frame, and a row of oil nozzles is provided on the outer surface of the rotating rod. One end of each row of oil nozzles is provided with a flexible hose, and the other end of each row of flexible hoses is connected to a first oil delivery pipe. One end of the first oil delivery pipe passes through the oil storage tank and is connected to the output end of the oil pump. A swinging component is provided on the drive shaft to drive the rotating rod to swing, and a cleaning component for cleaning the mold is provided on the side of the support frame.

[0006] Preferably, the swing assembly includes a rotating gear disposed on the outer surface of the rotating rod, a limiting groove is formed on one side of one of the support frames, a sliding plate is slidably connected inside the limiting groove, and a rack that meshes with the rotating gear is fixedly connected to one side of the sliding plate.

[0007] Preferably, an eccentric wheel is provided on the outer surface of one end of the drive shaft, the eccentric wheel is located directly below the rack, and the slide plate is trapezoidal.

[0008] Preferably, the cleaning component includes a support bar disposed on the side of the support frame, and an air bladder is installed on one side of the support bar, with an air vent at the bottom of each row of air bladders.

[0009] Preferably, a connecting post is fixedly connected to one end of the lower part of each row of fuel injectors, and a squeezing roller is provided at the other end of each row of connecting posts.

[0010] Preferably, the fuel injectors in a row are equidistant from each other, and the airbags in a row are also equidistant from each other.

[0011] Preferably, one end of the support frame is equipped with an automatic oil injection device, the input end of the automatic oil injection device is provided with a second oil supply pipe, and the other end of the second oil supply pipe is located inside the oil storage tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The oil is pumped from the storage tank to the first oil pipe and then discharged through the nozzle, achieving a uniform oil spraying effect on the mold surface. This avoids excessively thick or thin oil films in certain areas, reducing the risk of adhesion. Under constant pressure, the nozzle can atomize the oil into fine particles, enhancing adhesion and improving anti-sticking performance. It can also reduce labor and human error.

[0014] By using the swing component, the rotating rod and the oil nozzle can be driven to swing. When the oil nozzle sprays at a fixed position, it can only cover a local area, especially at the edge of the mold or in the recessed area, where dead corners are likely to occur. The swing of the oil nozzle can dynamically change the spray angle, cover more areas of the mold, and make the oil distribution more uniform.

[0015] The cleaning components are designed to clean the mold before spraying it with oil. Impurities such as residual sugar powder and dust on the mold surface can seriously affect the adhesion of the oil. Removing these impurities improves the bonding force between the oil and the mold, ensuring a non-stick effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides the following technical solution: an automated secondary spraying mold production line for preventing adhesion.

[0025] Example 1: To solve the problem of uneven oil spraying effect in existing mold production lines, the following is disclosed: two support frames 1, each with a drive shaft 2 rotatably connected inside; a conveyor line 3 (e.g., ...) is provided between the two drive shafts 2. Figures 1-3 As shown), a drive motor is installed at one end of a support frame 1, and the output end of the drive motor is connected to a drive shaft 2. An oil storage tank 4 is installed in the upper middle part of the support frame 1. An oil pump is installed inside the oil storage tank 4. A rotating rod 5 is rotatably connected inside the support frame 1. A row of oil nozzles 6 is provided on the outer surface of the rotating rod 5 (as shown). Figures 1-5 As shown), one end of each row of fuel injectors 6 is equipped with a hose, and the other end of each row of hoses is connected to a first fuel delivery pipe 7. One end of the first fuel delivery pipe 7 passes through the fuel storage tank 4 and is connected to the output end of the fuel pump. The drive shaft 2 is equipped with a swing assembly that drives the rotating rod 5 to swing. The swing assembly includes a rotating gear 8 set on the outer surface of the rotating rod 5. A limit groove is opened on one side of a support frame 1, and a sliding plate 9 (as shown) is slidably connected inside the limit groove. Figure 3 and Figure 6As shown), a rack 10 that meshes with a rotating gear 8 is fixedly connected to one side of the slide plate 9, which is used to drive the rotating gear 8 to rotate. An eccentric wheel 11 is provided on the outer surface of one end of a drive shaft 2. The eccentric wheel 11 is located directly below the rack 10. The slide plate 9 is trapezoidal. An automatic oil spraying device 15 is installed at one end of a support frame 1 for secondary oil spraying of the mold. The input end of the automatic oil spraying device 15 is provided with a second oil supply pipe 16. The other end of the second oil supply pipe 16 is located inside the oil storage tank 4.

[0026] First, start the drive motor to rotate the drive shaft 2, which in turn rotates the conveyor line 3. Then, place the mold on the conveyor line 3 (e.g., Figures 1-3 As shown, with the rotation of conveyor line 3, the mold then enters the oil spraying station. When the mold reaches the appropriate position, the oil pump is started, which transports the oil in the oil storage tank 4 to the oil spray nozzle 6 through the first oil pipe 7. The oil spray nozzle 6 then atomizes the oil and sprays it evenly onto the mold surface. At the same time, the drive shaft 2 rotates, which also drives the eccentric wheel 11 to rotate (as shown). Figures 1-3 As shown), when the eccentric wheel 11 contacts the rack 10, it pushes the rack 10 to move up and down. Then, the slide plate 9 slides up and down in the limiting groove, limiting the rack 10. As the rack 10 moves up and down, it drives the rotating gear 8 to swing, which in turn drives the rotating rod 5 to swing. The swinging of the rotating rod 5 drives the oil nozzle 6 to swing, achieving dynamic oil spraying and expanding the oil spray coverage. When the mold reaches below the automatic oil spraying device 15, the automatic oil spraying device 15 will deliver oil to the nozzle through the second oil supply pipe 16 for secondary oil spraying replenishment on the mold surface (e.g., ...). Figures 1-3 (As shown).

[0027] Example 2: Unlike Example 1, the cleaning component can clean the mold. It discloses that: a cleaning component for cleaning the mold is provided on the side of the support frame 1. The cleaning component includes a support strip 12 disposed on the side of the support frame 1, and an air bladder 13 is installed on one side of the support strip 12 (e.g., Figures 3-5 As shown), each of the airbags 13 has an exhaust port at its bottom to expel air from inside the airbag 13. Each row of fuel injectors 6 has a connecting post fixedly connected to one end of its lower part, and each connecting post has a squeeze roller 14 at its other end. The fuel injectors 6 are evenly spaced, and the airbags 13 are also evenly spaced (as shown). Figure 4 and Figure 5 (As shown).

[0028] As the fuel injector 6 oscillates, the connecting column also drives the extrusion roller 14 to oscillate. During the oscillation, the extrusion roller 14 applies periodic pressure to the airbag 13. After being compressed, the air inside the airbag 13 is released through the bottom exhaust port (e.g., Figure 5As shown), the exhaust port faces the mold surface, and the released compressed air can effectively blow away impurities such as sugar powder and dust from the mold surface. Because the airbags 13 and the spray nozzles 6 are equidistantly distributed, the cleaning range matches the spraying area (e.g., ...). Figure 4 and Figure 5 (As shown).
