Abstract
Description
Technical Field
[0001] The present application relates to the technical field of glass product production, and in particular to a scalding-free material taking device adapted for a glass mold. Background Art
[0002] Glass molds are special tools used to make glass products. They are usually made of high-temperature resistant materials and can withstand the high temperatures when the glass is melted. The shape and design of the mold depends on the shape and size of the glass product to be produced.
[0003] When glass products are manufactured, molten liquid glass is poured into a mold, and after it cools and solidifies into shape, workers take it out of the mold.
[0004] Since the temperature of liquid glass is as high as 1800℃, even after cooling and solidifying into shape, the temperature still remains at several tens of degrees. Therefore, when workers directly take the material manually, they may be burned by the glass products or molds, which is an obvious disadvantage. Utility Model Content
[0005] In order to improve the problem that workers may be scalded when manually taking materials, the present application provides a scalding-free material taking device suitable for glass molds.
[0006] The present application provides a scalding-free material taking device suitable for glass molds, which adopts the following technical solution:
[0007] A scalding-free material removal device suitable for glass molds comprises a negative pressure cylinder with a hollow interior and an open bottom, a lifting plate in close contact with the vertical inner wall of the negative pressure cylinder, a movable lifting rod that slides through the top of the negative pressure cylinder is arranged on the top of the lifting plate, and a frustum-shaped rubber adsorption skirt is arranged on the bottom of the negative pressure cylinder.
[0008] By adopting the above technical solution, when taking materials, the worker holds the negative pressure cylinder and presses the rubber adsorption skirt against the glass product, and then lifts the movable lifting rod upward, and the movable lifting rod drives the lifting plate to move upward, and the closed cavity enclosed by the lifting plate, the negative pressure cylinder, the rubber adsorption skirt and the glass product becomes a negative pressure state, so that the rubber adsorption skirt adsorbs the glass product through negative pressure, so that the worker can manually take the glass product out of the mold, and in the process of taking materials, the worker's hands will not directly contact the glass product and the mold, which is beneficial to reduce the possibility of workers being burned.
[0009] Optionally, a blowing pump electrically connected to the control system is placed next to the glass mold. The air outlet of the blowing pump is connected to the negative pressure cylinder through a hose. The connecting point between the hose and the negative pressure cylinder is located between the top of the negative pressure cylinder and the lifting plate. The negative pressure cylinder has an air outlet hole at a position relatively higher than the lifting plate.
[0010] By adopting the above technical solution, the air pump works and blows air into the negative pressure cylinder through the hose. When the lifting plate is outside the negative pressure cylinder, part of the air is discharged from the air outlet, and the remaining air is ejected from between the rubber adsorption skirt and the lifting block. In this way, when the negative pressure cylinder approaches the glass product, this part of the cold air will be blown onto the glass product, thereby improving the solidification degree of the glass product and reducing the possibility of deformation of the adsorption part of the glass product due to excessive negative pressure. When the lifting plate is inside the negative pressure cylinder, all the air blown into the negative pressure cylinder is discharged from the air outlet.
[0011] Optionally, a compression spring is provided between the inner top wall of the negative pressure cylinder and the lifting plate.
[0012] By adopting the above technical solution, when the worker takes the glass product out of the mold and places it in the designated position, the movable lifting rod is released. Under the action of the compression spring, it can automatically push the lifting block out of the negative pressure cylinder, thereby quickly releasing the adsorption state of the rubber adsorption skirt on the glass product, making it easier for the two to separate.
[0013] Optionally, a fixed lifting rod is arranged on the top of the negative pressure cylinder.
[0014] By adopting the above technical solution, the fixed lifting rod provides a stable force point for workers to manually pull the movable lifting rod.
[0015] Optionally, an inverted frustum-shaped wind collecting hood is arranged on the inner side wall of the rubber adsorption skirt, and the diameter of the wind collecting hood gradually decreases in a direction from top to bottom.
[0016] By adopting the above technical solution, the air collecting hood gathers the air flowing out from between the rubber adsorption skirt and the lifting block, so that the air can be concentrated to blow fan heat between the adsorption parts of the glass products, further improving the solidification degree of the corresponding positions of the glass products, and reducing the possibility of deformation of the glass products due to excessive force.
[0017] Optionally, the end of the rubber adsorption skirt with a smaller diameter is slidably sleeved on the circumferential outer side wall of the negative pressure cylinder and is tightened by a clamp.
[0018] By adopting the above technical solution, workers can replace the rubber adsorption skirt, which is suitable for the adsorption and extraction of different glass products.
[0019] Optionally, a fixed block is arranged at the top of the negative pressure cylinder, and a limit pin is horizontally slidably penetrated on the fixed block. A limit push rod is arranged in the negative pressure cylinder at a position above the lifting block and vertically slides through the top of the negative pressure cylinder. A plurality of limit holes that are plugged into and cooperate with the limit pin are vertically spaced apart on the limit push rod.
[0020] By adopting the above technical solution, the limiting pin is inserted and matched in different limiting holes, so that the adsorption force on the glass products can be adjusted, and the applicability of the material taking device is further improved.
[0021] Optionally, the lifting plate is coated with polytetrafluoroethylene.
[0022] By adopting the above technical solution, the friction coefficient of polytetrafluoroethylene is small, which is conducive to improving the smoothness of the lifting plate in the negative pressure cylinder. It is also more wear-resistant, reducing the possibility of air leakage between the lifting plate and the vertical inner wall of the negative pressure cylinder due to wear.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. When taking out the material, the worker holds the negative pressure cylinder and puts the rubber adsorption skirt close to the glass product, then lifts the movable lifting rod upward, and the movable lifting rod drives the lifting plate to move upward, and the closed cavity enclosed by the lifting plate, the negative pressure cylinder, the rubber adsorption skirt and the glass product becomes a negative pressure state, so that the rubber adsorption skirt adsorbs the glass product through negative pressure, so that the worker can manually take the glass product out of the mold, and during the material taking process, the worker's hands will not directly contact the glass product and the mold, which is conducive to reducing the possibility of workers being scalded;
[0025] 2. The air pump works and blows air into the negative pressure cylinder through the hose. When the lifting plate is outside the negative pressure cylinder, part of the air is discharged from the air outlet, and the remaining air is ejected from between the rubber adsorption skirt and the lifting block. In this way, when the negative pressure cylinder approaches the glass product, this part of the cold air will be blown onto the glass product, thereby improving the curing degree of the glass product and reducing the possibility of deformation of the adsorption part of the glass product due to excessive negative pressure;
[0026] 3. The air collecting hood gathers the air flowing out from between the rubber adsorption skirt and the lifting block, so that the air can be concentrated to blow the fan heat between the adsorption parts of the glass products, further improving the curing degree of the corresponding positions of the glass products and reducing the possibility of deformation of the glass products due to excessive force.

[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The embodiment of the present application discloses a scalding-free material taking device suitable for a glass mold.
[0033] Reference Figure 1 and Figure 2 The scald-free material taking device suitable for glass molds includes a negative pressure cylinder 1 with a hollow interior and an open bottom. A lifting plate 2 is provided in the negative pressure cylinder 1 and is in close contact with the vertical inner side thereof. The lifting plate 2 is horizontal.
[0034] The lifting plate 2 is coated with polytetrafluoroethylene, which has a small friction coefficient, so it can improve the smoothness of the lifting plate 2 moving in the negative pressure cylinder 1. In addition, polytetrafluoroethylene has high wear resistance, so it is helpful to reduce the possibility of air leakage between the lifting block and the inner wall of the negative pressure cylinder 1.
[0035] Reference Figure 1 and Figure 2 The top of the lifting plate 2 is threadedly connected with a movable lifting rod 3 that slides through the top of the negative pressure cylinder 1. A fixed lifting rod 6 is welded to the top of the negative pressure cylinder 1. The fixed lifting rod 6 provides a stable force point for workers to manually pull the movable lifting rod 3.
[0036] Reference Figure 1 and Figure 2 A compression spring 5 is supported between the inner top wall of the negative pressure cylinder 1 and the lifting plate 2. When the worker pulls the lifting plate 2 upward through the movable lifting rod 3, the compression spring 5 is compressed. When the worker releases the movable lifting rod 3, the deformation force of the compression spring 5 pushes the lifting block downward to automatically reset.
[0037] Reference Figure 1 and Figure 2 A rubber adsorption skirt 4 is provided on the sliding sleeve near the bottom of the circumferential outer wall of the negative pressure cylinder 1 and is clamped by a clamp 8. The rubber adsorption skirt 4 is in a frustum shape, and the diameter of the rubber adsorption skirt 4 gradually increases from top to bottom.
[0038] Reference Figure 1 and Figure 2A blowing pump (not shown in the figure) electrically connected to the control system is placed next to the glass mold. The air outlet of the blowing pump is connected to the negative pressure cylinder 1 through a hose 12. The connecting point between the hose 12 and the negative pressure cylinder 1 is located between the top of the negative pressure cylinder 1 and the lifting plate 2. The negative pressure cylinder 1 is provided with an air outlet 101 at a position relatively higher than the lifting plate 2.
[0039] Reference Figure 1 and Figure 2 When the worker holds the negative pressure cylinder 1 and approaches the glass product, the air pump works to blow the cold air from the outside into the negative pressure cylinder 1. At this time, the lifting plate 2 is located in the rubber adsorption skirt 4, and there is a gap between the lifting plate 2 and the rubber adsorption skirt 4.
[0040] Part of the air in the negative pressure cylinder 1 is blown out through the above-mentioned gap, and the remaining air is ejected from the air outlet 101. When the rubber adsorption skirt 4 is close enough to the glass product, the cold air is blown onto the glass product, thereby further dissipating heat and curing the glass product, reducing the possibility of deformation due to excessive force on the adsorption part of the glass product.
[0041] Reference Figure 1 and Figure 2 When the rubber adsorption skirt 4 is close to the glass product, the worker pulls the lifting block into the negative pressure cylinder 1 through the movable lifting rod 3, so that the closed cavity enclosed by the lifting plate 2, the negative pressure cylinder 1, the rubber adsorption skirt 4 and the glass product becomes a negative pressure state, so that the rubber adsorption skirt 4 adsorbs the glass product through negative pressure.
[0042] Through the above method, workers can manually take the glass products out of the molds, and during the process of taking out the materials, the workers' hands will not directly contact the glass products and the molds, which is helpful to reduce the possibility of workers being burned.
[0043] Reference Figure 1 and Figure 2 When the worker manually takes the glass product out of the mold and places it in the designated position, he releases the movable lifting rod 3, and the deformation force of the compression spring 5 can automatically push the lifting block out of the negative pressure cylinder 1, thereby quickly releasing the adsorption state of the rubber adsorption skirt 4 on the glass product, making it easier for the two to separate.
[0044] Reference Figure 1 and Figure 2 An inverted cone-shaped wind collecting hood 7 is integrally formed on the inner wall of the rubber adsorption skirt 4. The diameter of the wind collecting hood 7 gradually decreases from top to bottom. The wind collecting hood 7 gathers the air flowing out from between the rubber adsorption skirt 4 and the lifting block, further improving the air blowing, heat dissipation and curing effect on the adsorption part of the glass product.
[0045] Reference Figure 2 and Figure 3A fixing block 9 is integrally formed at the top of the negative pressure cylinder 1, and a limit pin 10 is horizontally slidably penetrated on the fixing block 9. A limit push rod 11 is vertically slidably penetrated through the top of the negative pressure cylinder 1 at a position above the lifting block in the negative pressure cylinder 1. A plurality of limit holes 111 for plugging and cooperating with the limit pin 10 are vertically spaced apart on the limit push rod 11.
[0046] The limiting pin 10 is inserted and fitted into different limiting holes 111, so that the distance between the end of the limiting push rod 11 and the lifting block can be adjusted, thereby controlling the size of the adsorption force on different glass products, further improving the applicability of the material taking device.
[0047] The implementation principle of a scalding-free material taking device adapted for a glass mold in the embodiment of the present application is as follows:
[0048] When the worker holds the negative pressure cylinder 1 and approaches the glass product, the air pump works to blow the external cold air into the negative pressure cylinder 1. At this time, the lifting plate 2 is located in the rubber adsorption skirt 4, and there is a gap between the lifting plate 2 and the rubber adsorption skirt 4.
[0049] Part of the air in the negative pressure cylinder 1 is blown out through the gap, and the remaining air is ejected from the air outlet 101. When the rubber adsorption skirt 4 is close enough to the glass product, the cold air is blown onto the glass product, thereby further dissipating heat and curing the glass product, reducing the possibility of deformation due to excessive force on the adsorption part of the glass product.
[0050] When the rubber adsorption skirt 4 is in close contact with the glass product, the worker pulls the lifting block into the negative pressure cylinder 1 through the movable lifting rod 3, so that the closed cavity enclosed by the lifting plate 2, the negative pressure cylinder 1, the rubber adsorption skirt 4 and the glass product becomes a negative pressure state, so that the rubber adsorption skirt 4 adsorbs the glass product through negative pressure.
[0051] The worker can manually take the glass product out of the mold, manually place it in the specified position, and then release the movable lifting rod 3. The deformation force of the compression spring 5 can automatically push the lifting block out of the negative pressure cylinder 1, thereby quickly releasing the adsorption state of the rubber adsorption skirt 4 on the glass product, and the rubber adsorption skirt 4 is separated from the glass product.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
