Description

Technical Field

[0001] The utility model relates to the field of glass manufacturing equipment, in particular to an energy-saving automatic rotary heating furnace for glass. Background Art

[0002] Glass production involves multiple steps, and after forming, the glass often undergoes a secondary heating process. This treatment aims to improve the glass's physical and chemical properties, enhancing its resistance to heat, cold, and compression, while also reducing internal stress and thermal expansion. In some cases, the glass's threaded opening and body may be manufactured separately, and reheating the body further allows for a tighter fit.

[0003] The existing method of heating glass cups is mostly to heat them in an electric furnace. The heating wire is set on the side wall of the heating furnace to ensure that the temperature inside the furnace body rises to achieve the heating effect. At present, whether it is flat glass, lead glass or borosilicate glass, an electric furnace can be used for heating treatment. The Chinese utility model patent with the authorization announcement number CN216337260U discloses a double-layer glass cup heating furnace, including a frame, an inner cup body, an outer cup body, a heating component and a lifting component. The heating component is locked and installed on the top of the frame, and a support plate is locked and installed inside the frame. However, the heating furnace adopts a linear arrangement for the heated cup body, so that the cup body in the middle and at both ends is heated unevenly, affecting the heating effect and reducing the yield rate. The defective products produced by heating need to be heated again, which will undoubtedly increase the overall energy consumption. In addition, the heating furnace uses a linear arrangement of lifting components, which requires loading and unloading of each lifting component at different positions, which is less efficient. Summary of the Invention

[0004] In view of the defects of the existing technology, the technical problem to be solved by the utility model is to provide an energy-saving automatic rotary heating furnace for glass cups, so that each cup body can be heated evenly, so as to improve the physical properties and chemical stability of the glass cup, and also make the glass cups made with the threaded mouth and the cup body separately fit more tightly, while meeting the requirements of each work station to load and unload at a fixed position, thereby enhancing the continuity of the processing process.

[0005] In order to solve the above technical problems, the utility model proposes an energy-saving automatic rotary heating furnace for glass cups, which adopts the following technical solutions:

[0006] An energy-saving automatic rotary heating furnace for glass cups comprises a feeding mechanism, a heating mechanism and a frame, and also comprises a rotating mechanism. The rotating mechanism is fixedly mounted on the frame, the feeding mechanism and the heating mechanism are fixedly mounted on the rotating mechanism, the heating mechanism is arranged above the feeding mechanism, the heating mechanism is arranged as a circular structure, at least two feeding mechanisms are provided, the feeding mechanisms are arranged at intervals along the circumferential direction, a loading hole is provided at the bottom of the heating mechanism, and the loading hole corresponds to the feeding mechanism.

[0007] The device can use a robotic loading mechanism to complete the loading process at a fixed position. The cup body is mounted on the feeding mechanism. After the feeding mechanism feeds the cup body into the charging hole of the heating mechanism, the rotating mechanism drives the feeding mechanism and the heating mechanism to rotate, causing the next feeding mechanism to rotate to the fixed position to load the cup. This cycle is repeated to complete the loading and feeding process. The robotic arm can also be set at a fixed position during the unloading process, and the process is repeated. With this method, because the heating mechanism is configured as a circular structure and the cup bodies are arranged circumferentially in the heating mechanism according to the arrangement of the feeding mechanism and the charging hole, the cup bodies can be evenly heated in the heating mechanism. This means that each heated cup body basically does not need to be heated again, reducing energy consumption, improving the physical properties and chemical stability of the glass, and also allowing glasses manufactured with separate threaded mouths and cup bodies to fit more tightly. Furthermore, unlike the prior art, the feeding stations in the prior art are arranged in a straight line, which requires all loading stations to be loaded and unloaded at different locations. In this application, the introduction of the rotating mechanism can meet the requirements that all feeding mechanisms can load materials at a fixed position and unload materials at a fixed position after heating, thereby improving work efficiency and facilitating mass production.

[0008] Furthermore, the heating mechanism includes a fixed plate and a heating furnace. The fixed plate is mounted on the bottom of the heating furnace. The heating furnace is circular, and a charging hole is provided on the fixed plate. The charging hole is electrically connected to the heating furnace. There are at least two charging holes, which are spaced circumferentially. The circular heating furnace can achieve all-round and uniform heating of the interior space of the heating furnace. The electric heating wire of the electric heating furnace is usually mounted on the side wall of the electric heating furnace. The heat generated by the heating wire circulates within the circular space, reducing heat loss and improving thermal efficiency. The circumferential arrangement of the charging holes also ensures that the temperature around each charging hole is the same, which is conducive to achieving uniform and efficient heating of the cup body placed in the charging hole.

[0009] Preferably, the feeding mechanism includes a feeding station, a lifting cylinder, and a guide rod. The guide rod is fixedly mounted at the bottom of the feeding station and slidably engages with a rotating mechanism. The lifting cylinder is fixed to the rotating mechanism, and the piston rod of the lifting cylinder is fixedly connected to the bottom of the feeding station. The guide rod design ensures a linear motion trajectory of the feeding station during the lifting process, effectively preventing deviation or shaking, thereby greatly improving feeding accuracy and the stability of the entire feeding mechanism.

[0010] Preferably, the feeding station is provided with a mounting portion that is the same size as the charging hole, coaxial with the charging hole, and slides in engagement. The mounting portion is designed to secure the cup within it, ensuring that it does not move during feeding, thereby ensuring accurate delivery of the cup into the charging hole. The mounting portion is the same size as the charging hole. When the mounting portion is raised into the charging hole, it prevents external air from contacting the cup, preventing the effects of varying temperatures on the cup that could affect heating.

[0011] Preferably, the rotating mechanism includes a turntable, a slewing bearing, and a drive unit. The slewing bearing is fixedly mounted at the bottom of the turntable, and the drive unit is located outside the slewing bearing. The high precision and low friction of the slewing bearing ensure smooth rotation of the turntable, facilitating precise control of the turntable's rotation angle and speed. Placing the drive unit outside the slewing bearing reduces energy loss and friction during transmission, improving the operating efficiency of the rotating mechanism and facilitating maintenance and adjustment of the drive unit.

[0012] Preferably, the drive device includes a drive motor and a gear, with the motor shaft of the drive motor facing upward. The gear is fixedly mounted on the motor shaft and meshes with the slewing bearing. The slewing bearing utilizes a conventional design with external gear teeth, thereby achieving meshing between the gear teeth and the gear. This ensures that the power generated by the drive motor is efficiently and stably transmitted to the turntable. This direct mechanical transmission method reduces energy loss during transmission, improves the overall efficiency of the system, and reduces mechanical wear caused by vibration.

[0013] Preferably, the turntable is provided with at least two positioning holes, spaced circumferentially, and the guide rods are slidably engaged with the positioning holes. The coordinated design of the positioning holes and the guide rods can reduce the shaking of the feed mechanism during operation of the turntable and reduce mechanical wear caused by inaccurate positioning or frequent adjustments.

[0014] In summary, the use of this energy-saving automatic rotary heating furnace for glass cups solves the problem of uneven heating of the cup body, improves the physical properties and chemical stability of the glass cup, and also enables glass cups made with the threaded mouth and cup body separately to fit more tightly, thereby improving the yield rate. At the same time, it meets the requirements that all feeding mechanisms can load materials at a fixed position and unload materials at a fixed position after heating, thereby enhancing the continuity of the processing process and improving work efficiency.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 4 An energy-saving automatic rotary heating furnace for glass cups is shown, comprising a feeding mechanism 1, a heating mechanism 2 and a frame 4, and also a rotating mechanism 3. The rotating mechanism 3 is fixedly mounted on the frame 4, the feeding mechanism 1 and the heating mechanism 2 are fixedly mounted on the rotating mechanism 3, the heating mechanism 2 is arranged above the feeding mechanism 1, the heating mechanism 2 is arranged as a circular structure, at least two feeding mechanisms 1 are provided, the feeding mechanisms 1 are arranged at intervals along the circumferential direction, and a loading hole 211 is provided at the bottom of the heating mechanism 2, and the loading hole 211 corresponds to the feeding mechanism 1.

[0023] The device can use a robotic loading mechanism to complete the loading process at a fixed position. The cup body is mounted on the feeding mechanism 1. After the feeding mechanism 1 feeds the cup body into the loading hole 211 of the heating mechanism 2, the rotating mechanism 3 drives the feeding mechanism 1 and the heating mechanism 2 to rotate, causing the next feeding mechanism 1 to rotate to the fixed position. This cycle is repeated to complete the loading and unloading process. The robotic arm can also be set at a fixed position during the unloading process, and the process is repeated. In this way, because the heating mechanism 2 is configured as a circular structure, and the cup body is arranged circumferentially in the heating mechanism 2 according to the arrangement of the feeding mechanism 1 and the loading hole 211, the cup body can be evenly heated in the heating mechanism 2. This means that each heated cup body basically does not need to be heated again, reducing energy consumption, improving the physical properties and chemical stability of the glass, and also allowing glasses manufactured with separate threaded mouths and cup bodies to fit more tightly. Furthermore, unlike the prior art, the feeding stations in the prior art are arranged in a linear manner, which requires all loading stations to be loaded and unloaded at different locations. In the present application, the introduction of the rotating mechanism 3 can meet the requirement that all feeding mechanisms can load materials at a certain fixed position and unload materials at a certain fixed position after heating, thereby improving work efficiency and facilitating mass production.

[0024] Further, such as Figure 3 As shown, the heating mechanism 2 includes a fixed plate 21 and a heating furnace 22. The fixed plate 21 is mounted on the bottom of the heating furnace 22. The heating furnace 22 is circular, and a charging hole 211 is provided on the fixed plate 21. The charging hole 211 is electrically connected to the heating furnace 22. There are at least two charging holes 211, and the charging holes 211 are spaced apart along the circumference. The use of a circular heating furnace 22 can achieve all-round and uniform heating of the interior space of the heating furnace 22. The electric heating wire of the electric heating furnace is usually arranged on the side wall of the electric heating furnace. The heat generated by the heating wire circulates within the circular space, reducing heat loss and improving thermal efficiency. The circumferential arrangement of the charging holes 211 also ensures that the temperature around each charging hole 211 is the same, which is conducive to achieving uniform and efficient heating of the cup body placed in the charging hole 211.

[0025] As a preference, Figure 2 As shown, the feeding mechanism 1 includes a feeding station 11, a lifting cylinder 12, and a guide rod 13. The guide rod 13 is fixedly mounted at the bottom of the feeding station 11 and slidably engages with the rotating mechanism 3. The lifting cylinder 12 is fixed to the rotating mechanism 3, and the piston rod of the lifting cylinder 12 is fixedly connected to the bottom of the feeding station 11. The design of the guide rod 13 ensures the linear motion trajectory of the feeding station 11 during the lifting process, effectively preventing deviation or shaking, thereby greatly improving the feeding accuracy and the stability of the entire feeding mechanism 1.

[0026] As a preference, Figure 2As shown, the feeding station 11 is provided with a mounting portion 111. The mounting portion 111 is the same size as the charging hole 211, and the mounting portion 111 and the charging hole 211 are coaxial and slidingly engaged. The design of the mounting portion 111 can secure the cup body therein, ensuring that the cup body does not move during feeding, thereby accurately feeding the cup body into the charging hole 211. The mounting portion 111 is set to the same size as the charging hole 211. When the mounting portion 111 is raised into the charging hole 211, it ensures that external air cannot come into contact with the cup body, preventing the different temperatures from affecting the heating effect of the cup body.

[0027] As a preference, Figure 2 As shown, the rotating mechanism 3 includes a turntable 31, a slewing bearing 32, and a drive device 33. The slewing bearing 32 is fixedly mounted at the bottom of the turntable 31, and the drive device 33 is located outside the slewing bearing 32. The high precision and low friction of the slewing bearing 32 ensure smooth rotation of the turntable 31, facilitating precise control of the rotation angle and speed of the turntable 31. Placing the drive device 33 outside the slewing bearing 32 reduces energy loss and friction during transmission, improving the operating efficiency of the rotating mechanism 3 and facilitating maintenance and adjustment of the drive device 33.

[0028] As a preference, Figure 2 As shown, the drive device 33 includes a drive motor 311 and a gear 332. The motor shaft of the drive motor 311 faces upward, and the gear 332 is fixedly mounted on the motor shaft. The gear 332 meshes with the slewing support bearing 32. The slewing support bearing 32 adopts a conventional design with external gear teeth, thereby achieving meshing between the gear teeth and the gear 332. This ensures that the power generated by the drive motor 311 is efficiently and stably transmitted to the turntable 31. This direct mechanical transmission method reduces energy loss during the transmission process, improves the overall efficiency of the system, and reduces mechanical wear caused by vibration.

[0029] As a preference, Figure 2 As shown, the turntable 31 is provided with at least two positioning holes 311, which are spaced circumferentially. The guide rods 13 slide in engagement with the positioning holes 311. The coordinated design of the positioning holes 311 and the guide rods 13 can reduce the shaking of the feed mechanism 1 during operation of the turntable 31, thereby reducing mechanical wear caused by inaccurate positioning or frequent adjustments.

[0030] In summary, the use of this energy-saving automatic rotary heating furnace for glass cups solves the problem of uneven heating of the cup body, improves the physical properties and chemical stability of the glass cup, and also enables glass cups made with the threaded mouth and cup body separately to fit more tightly, thereby improving the yield rate. At the same time, it meets the requirements that all feeding mechanisms can load materials at a fixed position and unload materials at a fixed position after heating, thereby enhancing the continuity of the processing process and improving work efficiency.

[0031] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
