Description

Technical Field

[0001] This invention relates to the field of glass forming auxiliary process technology, and specifically to a surface treatment device for the production of lightweight glassware. Background Technology

[0002] When glassware is first removed from the mold, it is subject to thermal stress due to temperature changes during the forming process. Especially when it is rapidly cooled from the high-temperature mold, the internal stress is not fully released. Therefore, flame spraying is usually required to eliminate the internal residual stress and prevent subsequent cracking or shattering.

[0003] Existing heat treatment equipment typically consists of a rotating carrier plate, on which a support plate for supporting the glassware is mounted. During operation, one of the support plates is preheated by spraying flames through a blower. Then, a robotic arm places the glassware from the mold onto the preheated support plate. As the carrier plate moves the glassware, flames are sprayed onto the glassware through the blower. To better release stress, a drive device is usually installed to rotate the support plate, allowing the flames to spray all around the glassware.

[0004] The existing technology has two main problems. First, the glassware varies in height, while the height of the flame tube remains constant. This results in some of the taller glassware not being sprayed by the flame and not fully releasing the stress. Second, the support plate cannot rotate while the flame tube is preheating the glassware. Otherwise, even without a driving force, the support plate will rotate due to inertia, and the robotic arm must wait for it to stop rotating before placing the glassware on the support plate. However, if the support plate does not rotate, the preheating will be concentrated at a single point, resulting in uneven heat transfer at the top of the support plate. This poses a risk of uneven heating and cracking of the glassware upon contact with the flame tube.

[0005] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to design a glass flame spraying treatment device that allows the support plate to be repeatedly raised and lowered when rotated by the driven component, so as to uniformly spray the flame onto the glassware. At the same time, it can be quickly stopped during separation, which facilitates loading and unloading of the robotic arm, thereby solving the above-mentioned shortcomings in the technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a surface treatment device for lightweight glassware production, comprising a frame, a carrier plate rotatably mounted on the frame, a support plate mounted on the carrier plate, a first flame-spraying pipe mounted on the frame to spray flame onto the carrier plate, and multiple second flame-spraying pipes mounted on the frame to spray flame onto the glassware on the support plate. A lifting rod is detachably mounted on the bottom of the support plate, the bottom of the lifting rod passing through the carrier plate and slidably connected to the carrier plate. A housing is fixedly mounted on the bottom of the lifting rod and detachably mounted to the bottom surface of the carrier plate. A lifting assembly for intermittently raising and lowering the lifting rod is installed inside the housing. A driven wheel is fixedly mounted on the input end of the lifting assembly. An arc-shaped drive assembly for driving the driven wheel to rotate is mounted on the frame. The support plates corresponding to the first and second flame-spraying pipes rotate, while one support plate between the first and second flame-spraying pipes does not rotate. The non-rotating support plate is the feeding plate.

[0008] The first flame nozzle preheats the top of the adjacent rotating support plate of the feeding tray by spraying fire, and the second flame nozzle heats the glassware on the top of the support plate. The lifting component, in conjunction with the arc-shaped drive component, drives the support plate to rise and fall intermittently.

[0009] Preferably, the lifting assembly includes a drive shaft passing through the bottom of the housing, a driven shaft slidably mounted on the top of the drive shaft, a transmission rod fixedly mounted on the outer circumferential surface of the lifting rod, and a wave-shaped groove formed on the inner circumferential surface of the housing. The end of the transmission rod is inserted into the groove and slidably connected. The driven wheel is mounted on the drive shaft, and the driven shaft is fixedly mounted on the bottom end of the lifting rod.

[0010] Preferably, a chassis is fixedly installed on the top of the outer peripheral surface of the drive shaft, a top plate is fixedly installed on the outer peripheral surface of the lifting rod, and a spring is installed between the top plate and the chassis.

[0011] Preferably, the drive shaft includes a first shaft that passes through the bottom of the housing and is rotatably connected to the housing, and a blind hole opened at the top of the first shaft, and the driven shaft is vertically slidably connected within the blind hole.

[0012] Preferably, the blind hole is a hexagonal slot and the driven shaft is a hexagonal prism.

[0013] Preferably, when the transmission rod is located at the top of the slide groove, the bottom end of the driven shaft is located inside the blind hole; when the transmission rod is located at the bottom of the slide groove, the bottom end of the driven shaft does not contact the bottom end of the blind hole cavity.

[0014] Preferably, the drive assembly includes two first drive wheels, two second drive wheels, two third drive wheels, and two fourth drive wheels rotatably mounted on a frame, and an external gear belt that is rolledly connected to the first drive wheels, second drive wheels, third drive wheels, and fourth drive wheels, wherein the driven wheel and the third drive wheel both mesh with the external gear belt.

[0015] Preferably, when the driven wheel corresponding to the first flame tube and the driven wheel corresponding to the second flame tube are engaged with the external gear belt, the driven wheel between the first flame tube and the second flame tube are not engaged with the external gear belt, and a motor that drives one of the first transmission wheels to rotate is installed on the frame.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] 1. The present invention, through the cooperation of the lifting component and the driving component, enables the glassware on the support plate to be repeatedly raised and lowered while rotating when the second flame tube sprays flame onto the glassware, so that the flame can be sprayed evenly onto the surface of the glassware, so that glassware of different heights are sprayed with flame at the vertical height to release stress.

[0018] 2. The present invention, through the design of the drive component, enables the support plate to rotate when it is preheated by the first flame tube, ensuring uniform preheating of the top of the support plate. When it rotates around the carrier plate to the next station, it becomes the feeding plate and is no longer subject to driving force. Then the carrier plate drives the feeding plate to rotate to the next station and then begins to rotate under driving force.

[0019] 3. At the same time, the invention, in conjunction with the spring, top plate and bottom plate, can enable the loading plate to stop quickly and abruptly, without continuing to rotate due to inertia, which would require an extra long waiting time for the loading plate to stop rotating. Furthermore, all support plates can maintain a uniform height after the emergency stop, which facilitates loading and unloading. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] This invention provides, for example Figure 1-6 The surface treatment apparatus shown is based on the production of lightweight glassware. It includes a frame 1, a carrier plate 2, a support plate 3, and flame tubes as in the prior art. The carrier plate 2 is rotatably mounted on the frame 1 and rotates intermittently under the control of a power source. There are multiple support plates 3, which are arranged in a ring array on the carrier plate 2. One of them is a loading plate 11, which is used to support the glassware that the robotic arm has just taken out of the mold in a stationary state. The flame tubes are divided into a first flame tube 4 and a second flame tube 5. The first flame tube 4 sprays flames towards the support plate 3 on the adjacent side of the loading plate 11 to preheat it. Multiple second flame tubes 5 are set as needed to spray flames onto the glassware on the support plate 3 on the other side of the loading plate 11 to eliminate residual stress in the glassware.

[0032] like Figures 4-6As shown, since the glassware varies in height while the height of the flame tube remains constant, a portion of the taller glassware may not be fully exposed to the flame, resulting in incomplete stress release. To address this, a lifting rod 6 is detachably installed at the bottom of the support plate 3, passing through and slidingly connecting to the support plate 2. A driven shaft 8b is fixedly installed at the bottom of the lifting rod 6. Below the driven shaft 8b, a first shaft 8a1 with a blind hole 8a2 at the top is positioned. The first shaft 8a1 with the blind hole 8a2 constitutes the driving shaft 8a, allowing the driven shaft 8b to slide vertically within it. A housing 7 is detachably connected to the bottom of the support plate 2, and the bottom of the first shaft 8a1 passes through and rotates within it. A driven wheel 9 is fixedly installed on part of the outer shell 7. A wave-shaped groove 8d is opened on the inner circumferential surface of the outer shell 7. A transmission rod 8c, which is fixedly installed on the outer circumferential surface of the lifting rod 6, is slidably installed in the groove 8d. The transmission rod 8c, the driven shaft 8b, the groove 8d, and the drive shaft 8a constitute the main part of the lifting assembly 8. In this way, as long as the driven wheel 9 is driven to rotate, the driven wheel 9 will drive the first shaft 8a1. The first shaft 8a1 drives the lifting rod 6 to rotate through the blind hole 8a2 and the driven shaft 8b. When the lifting rod 6 rotates, it will drive the transmission rod 8c to repeatedly rise and fall in the wave-shaped groove 8d, thereby driving the lifting rod 6 to repeatedly rise and fall on the support plate 2, so as to drive the glassware to rotate and rise and fall at the same time, so that the flame is evenly sprayed on its surface.

[0033] like Figure 2 and Figure 3 As shown, in order for the support plate 3 to rotate when the first flame pipe 4 sprays flame onto the support plate 3, and when the second flame pipe 5 sprays flame onto the glassware, but not to be driven to rotate when the feeding plate 11 corresponding to the support plate 3 is feeding, we rotatably install two first transmission wheels 10a, two second transmission wheels 10b, two third transmission wheels 10c, and two fourth transmission wheels 10d on the frame 1, and external gear belts 10e rollingly connected to the first transmission wheels 10a, second transmission wheels 10b, third transmission wheels 10c, and fourth transmission wheels 10d. The driving wheel 10d and the external gear belt 10e constitute the drive assembly 10. The driven wheel 9 and the third transmission wheel 10c are both meshed with the external gear belt 10e. When the driven wheel 9 corresponding to the first flame tube 4 and the driven wheel 9 corresponding to the second flame tube 5 are meshed with the external gear belt 10e, the driven wheel 9 between the first flame tube 4 and the second flame tube 5 is not meshed with the external gear belt 10e. Furthermore, a motor 15 is installed on the frame 1 to drive one of the first transmission wheels 10a to rotate. When the motor 15 rotates, it will drive the first transmission wheel 10a to rotate. The first transmission wheel 10a will drive the external gear belt 10e to move, thereby driving the driven wheel 9 meshing with the external gear belt 10e to rotate.

[0034] like Figures 5-6 As shown, after the support plate 3, which is sprayed by the first flame tube 4, rotates, even after the corresponding driven wheel 9 separates from the external gear belt 10e, it still has inertia and continues to rotate. Meanwhile, the bearing plate 2, after rotating a certain angle, needs to stop rotating quickly to form the loading plate 11, which is convenient for the robotic arm to place the glassware on it. Therefore, a base plate 12 is fixedly installed on the top of the outer circumference of the drive shaft 8a, and a top plate 13 is fixedly installed on the outer circumference of the lifting rod 6. A spring 14 is installed between the top plate 13 and the base plate 12. This way, once there is no external force driving the lifting rod... If the rotation of the top plate 13 overcomes the elastic force of the spring 14, the spring 14 will return to its original position, making the gap between the top plate 13 and the bottom plate 12 larger and farther apart. The top plate 13 will drive the lifting rod 6 to rise, and the lifting rod 6 will drive the transmission rod 8c to move to the top of the slide 8d. If the lifting rod 6 wants to move to the bottom of the slide 8d, it needs to overcome the elastic force of the spring 14. Even if the lifting rod 6 rotates several times under the action of inertia, it will eventually stop quickly under the action of the spring 14, changing from the rotating support plate 3 that has just been preheated by the first flame pipe 4 to the stationary feeding plate 11.

[0035] Now let's summarize the overall workflow: When the carrier plate 2 rotates intermittently, it drives the support plate 3 to rotate around the carrier plate 2, causing the driven wheel 9 on the carrier plate 2 to mesh with the external gear belt 10e, thus causing it to rotate. At this time, the first flame pipe 4 sprays flames to preheat its surface. Then, the carrier plate 2 rotates to a predetermined angle and stops rotating, causing the driven wheel 9 on the preheated support plate 3 to separate from the external gear belt 10e. The spring 14 corresponding to this support plate 3 will drive this support plate 3 to stop quickly under the action of elastic force, and stop rotating to form the loading plate 11. Then, the existing robotic arm places the glassware with the production number in the mold onto the loading plate 11. After that, the carrier plate 2 rotates to a predetermined angle again, causing the driven wheel 9 on the loading plate 11 to mesh with the external gear belt 10e again and rotate. At this time, the second flame pipe 5 sprays flames onto the surface of the glassware that is moving up and down while rotating. After the carrier plate 2 rotates intermittently several times, the processed glassware is moved to the side of the unloading robotic arm to be unloaded.

[0036] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
