Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, in particular to equipment for producing glass products, and specifically relates to a multi-station device for continuously producing glass cups or the like. Background Art

[0002] Glass cups are divided into many styles, such as handleless plain cups, high-foot cups, and glass cups with handles on the side. In the manufacturing process of glass cups, the manufacture of the cup handle is generally prefabricated and produced separately, which is formed by bending the glass rod after heating or prefabricated into the designed shape. There are generally two methods for producing the glass cup body. One is to put the nearly molten glass cup barrel into a preset mold and blow it into the designed shape. The other is to directly cut a glass tube of a certain specification into sections, and then seal the bottom and burn the glass tube sections to form a glass cup body. The high-foot or handle glass cup is welded with a cup foot or a cup handle (handle) on the bottom or side of the cup body. The existing production process of glass cups with handles or feet generally processes the glass cup body and the cup handle or cup foot first, and then transfers it to the welding handle equipment to weld the handle or cup foot. After the welding is completed, the glass cup must be annealed to prevent the molten glass from cooling too quickly and cracking. In the prior art, the forming of the cup body, the forming of the cup handle, and the welding between them need to be completed on different equipment, so the production efficiency is low.

[0003] When a glass tube or the like is used to prepare a cup body, the glass tube is cut into a fixed process length or twice the length, and then the glass tube is clamped on a rotating chuck. One end or the middle part of the glass tube is roasted with a high-temperature and high-speed flame in a rotating state, so that the glass here reaches a molten state and extends and fuses toward the center of the glass tube under the blowing force of the flame, forming a complete, smooth and flat cup bottom; when a glass tube of twice the length is used and the middle part of the glass tube is burned, the glass tube of twice the length is first cut in the middle with a flame to form two cup bodies, and then the cut part is burned to form a glass cup bottom; the other end of the glass tube is the cup mouth, which also needs to be melted with a flame in advance or in a later sequence to form a smooth edge. After the cup body is formed, during the process of welding the cup handle, the cup body is generally clamped on a chuck, and the cup handle is also clamped by a clamping claw to align the two, and then a flame is used to burn the end of the cup handle and the welding part of the cup body at the same time. When they reach a molten state, a relative movement occurs between the mechanism for clamping the cup body and the mechanism for clamping the cup handle, so that the cup handle and the molten part of the cup body come into contact, completing the welding.

[0004] Because glass has poor thermal conductivity, it is generally necessary to preheat the glass before each heating and melting, and then melt it with high heat. After melting or welding, the formed glass cup must also be kept warm to allow it to cool slowly (this step is commonly known as annealing). If these two steps are not done well, the glass will crack during or after the production process.

[0005] There are many devices for producing glass cups and the like. For example, in the patent document with the publication number CN117361860A, a glass handle and a glass cup automatic welding device is disclosed, which includes a welding platform, a mounting seat, a first driving member, and a welding gun. The mounting seat and the first driving member are installed on the welding platform, and a screw rod is connected to the output shaft of the first driving member. The screw rod rotates through the mounting seat, and the welding gun is installed on one side of the mounting seat. A cup body feeding assembly for conveying the glass cup body to the welding gun for welding is provided on one side of the welding platform. The first driving rod drives the handle conveying frame to move and convey the glass handle to the welding gun. The welding gun burns the glass cup body and the glass handle, and then the burnt glass handle is attached to the burnt glass cup body through the handle conveying frame to realize the connection between the glass handle and the glass cup body, thereby realizing the function of automatically and efficiently welding the glass handle to the glass cup body. In addition, WO2007057070A1 also discloses a device for producing high-heeled glasses, which is a multi-station continuous welding device for the foot and body of high-heeled glasses. The foot and the body are respectively clamped on a fixture so that they are opposite to each other up and down, and then when the horizontal turntable is turned to a station, the end of the foot and the bottom of the body are melted by a flame burner, and then it is turned to the next station so that the molten foot and the body are in relative contact to connect them together, and a smooth welding part and the mouth of the glass are formed at the subsequent station.

[0006] When the above equipment is in use, the glass body and the handle are prefabricated, and the prefabricated glass body and handle are placed on the welding equipment for welding, resulting in low efficiency in producing glass cups. Utility Model Content

[0010] In the equipment for producing glass cups of the utility model, the above-mentioned rotating drum has two sets of flame heating mechanisms that can move left and right and are arranged mirror-symmetrically on both sides of the bottom sealing station. The cup body clamping mechanisms on the two rotating drums can rotate synchronously at the bottom sealing station. The welding handle station and annealing station of each of the two rotating drums are correspondingly provided with flame heating mechanisms; after the bottom sealing is completed, the two cup body clamping mechanisms rotate with the rotating drums where they are located and respectively complete the welding handle, annealing and unloading.

[0011] A further improvement of the technical solution of the utility model is that: the flame heating mechanism at the bottom sealing station is located below the glass tube clamped by the cup body clamping mechanism; a loading mechanism is provided at the bottom sealing station, the loading mechanism comprises a loading bracket and a loading manipulator corresponding to the loading bracket, and the loading bracket enables the glass tube waiting for processing to be higher than the flame heating mechanism of the bottom sealing station.

[0012] A further improvement of the above technical solution of the utility model lies in that: the loading bracket includes a material receiving trough, which, driven by the pneumatic rod, has a position corresponding to the cup body clamping mechanism of the bottom sealing station and a preheating position higher than the flame heating mechanism of the bottom sealing station; the loading robot clamps the glass tube on the material receiving trough and sends it to the cup body clamping mechanism of the bottom sealing station, where the glass tube is automatically clamped by the cup body clamping mechanism.

The claws of the three-jaw chuck are controlled by a control mechanism so that the claws can be opened at the unloading station and the bottom sealing station.

[0015] A further improvement of the above technical solution of the utility model lies in that: each of the three-jaw chucks is connected to the rotating drum through a rotating tube, the rotating tube passes through the rotating drum and realizes the self-rotation of the rotating tube and the three-jaw chuck under the drive of the rotating gear installed on the rotating tube; when multiple rows of cup body clamping mechanisms are arranged on the same workstation, the rotating gears of two adjacent cup body clamping mechanisms in the same row are meshed and connected with a transition gear for making the three-jaw chuck rotate synchronously; a self-rotation driving mechanism for driving the rotating gear at the end of the rotating drum at the bottom sealing station is arranged at one end of the rotating drum corresponding to the bottom sealing station.

[0016] A further improvement of the above technical solution of the utility model is that a claw push rod for opening the claws of the three-jaw chuck is arranged in the rotating tube, and one end of the claw push rod extends out of the rotating drum and corresponds to the control mechanism located in the rotating drum.

[0017] A further improvement of the above technical solution of the utility model lies in that: the control mechanism includes a camshaft located in the rotating drum and having a cam corresponding to the claw push rod on a circle coaxially arranged with the rotating drum. The camshaft rotates between the unloading station and the bottom sealing station under the drive of the camshaft cylinder, and the cam squeezes the claw push rod to open the claws of the three-jaw chuck at the unloading station and the bottom sealing station.

[0018] A further improvement of the technical solution of the utility model is that it also includes a positioning device for fixing the orientation of the cup body clamping mechanism on the welding handle position, the positioning device includes a positioning mechanism corresponding to the welding handle position and a triangular positioning piece fixed on the cup body clamping mechanism; the positioning mechanism includes an arc-shaped positioning plate with a guide angle supported by a spring rod; when the cup body clamping mechanism rotates to the welding handle position driven by the rotating drum, one edge of the triangular positioning piece cooperates with the end face of the arc-shaped positioning plate to finally come into stable contact.

[0019] A further improvement of the technical solution of the utility model is that: the cup handle clamping mechanism is arranged at a position corresponding to the cup body clamping mechanism of the welding handle station and can move left and right relative to the cup body clamping mechanism of the welding handle station; a flame heating mechanism for the welding handle is arranged between the cup handle clamping mechanism and the cup body clamping mechanism, which can move left and right with the rotating drum and can move up and down along the second vertical guide rail.

[0020] A further improvement of the above technical solution of the utility model lies in that: the cup handle clamping mechanism includes a cup handle manipulator corresponding to the cup body clamping mechanism; the cup handle manipulator includes two second clamping plates driven by a second bidirectional cylinder and capable of opening and closing left and right at the same time, one of the second clamping plates has an adjustment block on its inner side for adjusting the gap between the two clamping plates, a cup handle clamping groove capable of clamping cup handles of different widths is formed between the two second clamping plates, and a support plate is provided at the bottom of the second clamping plate; a gravity holding block is eccentrically arranged on the upper part of the cup handle clamping groove.

[0022] A further improvement of the technical solution of the utility model is that the flame heating mechanism on the annealing station is a flame spraying cover installed on a frame and can move horizontally relative to the cup body clamping mechanism on the annealing station.

[0023] A further improvement of the technical solution of the utility model is that a transport mechanism for receiving the glass cups is arranged below the unloading station.

[0024] Due to the adoption of the above technical solution, the technical advances achieved by the utility model include:

[0025] The equipment for producing glass cups or the like of the utility model can complete the bottom sealing, handle welding, and annealing processes in the cup making process on one device, and can automatically unload parts, thereby greatly improving the production efficiency. In addition, the four stations of the utility model are respectively provided with cup body clamping mechanisms (of course, only one cup body clamping mechanism can be provided, and it can be transferred to different stations in turn, but the production efficiency is too low in this way), so the four stations can work simultaneously and separately; multiple cup body clamping mechanisms and flame heating mechanisms can also be arranged side by side on each station (of course, only one can be arranged on one station), so multiple cups can be processed at one station at the same time, greatly improving the production efficiency. In the equipment for producing glass cups, at the bottom sealing station, through the mutual cooperation of the cup body clamping mechanisms located on both sides of the flame heating mechanism, the two cup body clamping mechanisms simultaneously clamp a glass tube and rotate synchronously, and can automatically melt and split a glass tube into two sections at the same time, and seal the bottoms of them respectively, and can use a glass tube to form two cup bodies at the same time, further improving the production efficiency and saving energy. Then, at the handle welding station, the handle clamping mechanism, the body clamping mechanism, and the flame heating mechanism cooperate with each other to automatically bond the handle to the bottom-sealed glass body. The utility model combines the steps of glass tube segmentation, bottom sealing, bonding of the glass body and the handle, annealing, unloading of the glass, and transportation to realize automatic continuous production, thereby improving the production efficiency of the glass. After one process is completed, the next process can be immediately carried out while the glass is still in a high temperature state, thus saving burning energy and time.

[0026] The equipment for producing glass cups of the utility model has four sets of cup body clamping mechanisms arranged circumferentially on a circumference of a rotating drum. These four sets of cup body clamping mechanisms form a set of glass cup manufacturing processes. Other cup body clamping mechanisms arranged axially can also be arranged at each station on the circumference of the rotating drum, so that each station has multiple axially arranged cup body clamping mechanisms. There are multiple rows of cup body clamping mechanisms on the rotating drum. Of course, corresponding arrangements are also required when flame heating is required. In this way, processes such as glass tube segmentation, bottom sealing, handle welding, annealing, etc. can be performed on multiple workpieces at the same time.

[0027] The utility model arranges a loading bracket so that the glass tube to be processed is located above the flame generated by the flame heating mechanism of the bottom sealing station. When the flame heating mechanism of the bottom sealing station divides and seals the glass tube, its excess heat can be used to preheat the glass tube to be processed, thereby saving preheating time and energy. After experimental comparison, the equipment omits the preheating step of the glass tube, and only the melting bottom sealing step can save about 20% of gas, shorten the time for cutting the bottom sealing by about 15%, and can put the glass tube to be processed in the preheating position in advance, thereby reducing the loading time.

[0028] The material receiving groove of the feeding bracket of the utility model is driven by an inclined pneumatic rod to realize the two positions of preheating and feeding, while the feeding robot can only move between the upper and lower positions, which simplifies the movement mode of the feeding robot and makes the positions of clamping and feeding more accurate.

[0029] The feeding manipulator and the cup handle manipulator of the cup handle clamping mechanism of the utility model are driven by a bidirectional cylinder, and their clamping plates can be opened and closed at the same time, so that even if the glass tubes or cup handles have different diameters or widths, their center lines can be kept in one position, which is convenient for the cup body clamping mechanism to accurately clamp the glass tube or align the cup handle with the cup body. After the feeding manipulator and the cup handle manipulator complete their work, each manipulator will leave the working position and enter a waiting state.

[0030] The three-jaw chuck of the cup body clamping mechanism of the utility model uses a structure in which the jaws can be automatically retracted, and the jaws can be opened by a control mechanism at the unloading station and the bottom sealing station. At the bottom sealing station, when the jaws are opened and reach the glass tube position, the jaws automatically retract to clamp the glass tube, and then complete the segmentation and bottom sealing of the glass tube in a rotating state. When the cup body clamping mechanism reaches the unloading station, the jaws of the three-jaw chuck are also automatically opened under the control of the control mechanism, so that the finally formed glass cup is unloaded on the transport mechanism.

[0031] The jaws are opened by the action of the jaw push rod, which is controlled by the control mechanism. The control mechanism of the utility model is to set a camshaft at the center of the drum, which drives the cam to rotate between the unloading station and the bottom sealing station, and the jaws of the three-jaw chuck are opened by squeezing the jaw push rod. When the cam leaves, the jaws are contracted and are in a clamping state.

[0032] In the above scheme of the utility model, the self-rotation of the three-jaw chuck at the bottom sealing station is driven by the rotating gear connected to the three-jaw chuck, and the rotating gear is connected to the self-rotation driving mechanism when the rotating tube is rotated to the bottom sealing station, and the self-rotation driving mechanism drives the rotating tube and the three-jaw chuck on the rotating tube to rotate. If multiple rows of cup body clamping mechanisms are arranged on the rotating drum, a transition gear is also arranged between the rotating gears of each cup body clamping mechanism to make the three-jaw chucks of each row rotate synchronously.

[0033] The utility model is provided with a positioning device on the welding handle station. When the cup body clamping mechanism is transferred to the welding handle station, its orientation is fixed, thereby preventing the glass cup handle from sticking crookedly. This is conducive to the cup handle aligning with the cup body and is not affected by the claws of the cup body clamping mechanism. When the cup body clamping mechanism enters the welding handle station, the triangular positioning piece contacts the end face of the arc-shaped positioning plate, prompting the cup body clamping mechanism to rotate. Finally, one edge of the triangular positioning piece forms a stable contact with the end face of the arc-shaped positioning plate. The triangular positioning piece and the arc-shaped positioning plate designed by the positioning device have a simple structure and accurate positioning. The spring of the positioning mechanism can make the positioning plate have a certain telescopic force, so that when the triangular positioning piece contacts it, it can achieve a buffering effect. The positioning plate is an arc-shaped positioning plate that matches the shape of the rotating drum, and its introduction end has a guide angle to facilitate the entry of the triangular positioning piece. The positioning piece is in a triangular shape, and its triangular sides correspond to the claws of the three-jaw chuck. When one triangular side of the positioning piece is in integral contact with the end face of the positioning plate, one of the claws is away from the cup handle. This ensures that when the cup handle is welded, the cup handle will not touch the claw, and the claw will not affect the contact between the cup handle and the cup body, while preventing the glass cup body from rotating.

[0034] The utility model arranges the welding handle station above the rotating drum. When the cup body clamping mechanism is at the welding handle station, the cup handle clamping mechanism corresponds to the cup body clamping mechanism at the welding handle station, and the cup handle clamping mechanism can move left and right relative to the cup body clamping mechanism; and the flame heating mechanism of the welding handle station is located between the cup handle clamping mechanism and the cup body clamping mechanism. The flame heating mechanism and the rotating drum are installed on a sliding seat and can move left and right together with the rotating drum, so that the positional relationship with the cup body clamping mechanism can be ensured; the flame heating mechanism can also move up and down. After the cup handle and the cup body are heated and melted, the flame heating mechanism rises and leaves the position for burning the cup handle and the cup body, and the cup handle clamping mechanism and the cup body clamping mechanism are close to each other, so that the cup handle is welded to the cup body. The structural design of the cup handle manipulator of the cup handle clamping mechanism of the utility model can not only clamp cup handles of different widths or diameters, but also the support plate at the bottom can hold the cup handle, and the upper holding block can hold the cup handle by its own gravity. With the addition of two second clamping plates, the cup handle manipulator forms a groove to accommodate the cup handle, so it can stably clamp cup handles of different shapes or sizes; the number of cup handle manipulators corresponds to the number of rows of cup body clamping mechanisms on the same workstation and rotating drum, and the cup handle manipulator is driven by the second sliding seat and the power machine as a whole, and one action can simultaneously complete the welding of multiple cup handles and cup bodies. The cup handle clamping mechanism can adjust the height by a height adjustment mechanism such as a screw to align the height of the cup handle with the welding position on the cup body.

[0035] The utility model uses a cover tube to cover the glass cup arriving at the annealing station. When the cup body clamping mechanism drives the clamped glass cup to the annealing station, the flame hood installed on the frame moves horizontally and covers the glass cup, applying a weak flame to the glass cup to achieve the purpose of slow cooling annealing.

[0036] When the cup body clamping mechanism drives the clamped glass cup to the unloading station, the clamping claws of the three-jaw chuck open and place the glass cup on the conveyor belt or other transportation mechanism below it. During the transfer process, the glass cup cools down naturally and the next process can be operated at room temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. In the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0052] Embodiment 1

[0053] First reference Figure 1 .according to Figure 1 It can be seen that the utility model includes three flame heating mechanisms 3 installed on the frame 1, and the three flame heating mechanisms 3 are respectively used for the bottom sealing of the glass tube 3, the flame heating mechanism 3 for the welding handle, and the flame heating mechanism 3 for annealing, which correspond to the bottom sealing station 101, the welding handle station 102, and the annealing station 103. A rotating drum 10 is respectively arranged on both sides of the flame heating mechanism 3 of the bottom sealing station 101, and the two sets of rotating drums 10 are arranged in a mirror-symmetrical manner with the flame heating mechanism 3 of the bottom sealing station 101 as the center. The rotating drum 10 can be respectively installed on two first sliding seats 13 located on the frame 1, and the first sliding seat 13 can carry the rotating drum 10 to slide horizontally along the left and right length directions of the frame 1 under the drive of the power machinery, and their left and right moving directions are opposite, and they can move to the middle at the same time, or to the left and right sides at the same time. Each rotating drum 10 is provided with a cup body clamping mechanism 2. When the rotating drum 10 moves toward the middle, the cup body clamping mechanisms 2 at the bottom sealing station 101 on the two rotating drums are opened and respectively clamp the glass tube at the bottom sealing station 101 to rotate synchronously. After the cutting and bottom sealing are completed at the bottom sealing station, the two cup body clamping mechanisms 2 rotate in a vertical plane with the rotating drums 10 where they are located, and respectively complete the welding handle, annealing and unloading.

[0054] A set of cup body clamping mechanisms 2 can have four, and these four cup body clamping mechanisms 2 are evenly distributed on the same circumference of the rotating drum 10; the rotating drum 10 rotates in a stepping manner, and drives the cup body clamping mechanism 2 to rotate to different positions in the vertical plane during rotation. The workstations of the utility model are divided into a bottom sealing station 101, a welding handle station 102, an annealing station 103, and an unloading station 104. The bottom sealing station 101 and the annealing station 103 are located on the left and right sides of the rotating drum 10, the welding handle station 102 is located at the upper part of the rotating drum 10, and the unloading station 104 is located at the lower part of the rotating drum 10. The bottom sealing station 101, the welding handle station 102 and the annealing station 103 are all provided with flame heating mechanisms 3; the flame heating mechanism 3 of the bottom sealing station 101 is located below the glass tube clamped by the cup body clamping mechanism 2 of this station; at the welding handle station 102, in addition to the cup body clamping mechanism 2, a corresponding cup handle clamping mechanism 4 is also provided, the flame heating mechanism 3 of the welding handle station is located between the cup body clamping mechanism 2 and the cup handle clamping mechanism 4, and can move up and down, the flame heating mechanism 3 of the welding handle station 102 is used to burn the glass cup body and glass cup handle at the welding handle station 102; the flame heating mechanism of the annealing station 103 is used to bake the glass cup after the welding handle, so that the temperature of each part is uniform and no brittle cracking occurs. A transport mechanism 9 is provided below the unloading station 104, and the transport mechanism 9 can adopt a conveyor belt or a transport trolley commonly used in traditional technology.

[0055] Of course, the utility model can be provided with only one rotating drum 10, rather than two mirror-symmetrically arranged on both sides of the bottom sealing station 101. When one rotating drum 10 is provided, the cup body clamping mechanism 2 on the rotating drum corresponds to the flame heating mechanism 3 of the bottom sealing station 101, but such a setting will reduce the production efficiency by more than 50% compared with the structure of mirror-setting two sets of rotating drums 10. Although such a setting is also within the protection scope of the utility model, the utility model recommends the use of two sets of rotating drums 10 with cup body clamping mechanisms 2 arranged in mirror-symmetrical manner. These two rotating drums 10 can use only one set of flame heating mechanism 3 at the bottom sealing station 101, and use the flame heating mechanism of the welding handle at the welding handle station 102 and the flame heating mechanism for annealing at the annealing station 103 respectively.

[0056] In addition, there can be multiple cup body clamping mechanisms 2 arranged on each rotating drum 10 of the utility model. One or several cup body clamping mechanisms 2 that rotate in the same vertical plane and step sequentially between four stations can be called a group; and several cup body clamping mechanisms 2 can be arranged on each station, and one or more cup body clamping mechanisms 2 at the same station can be called several rows, that is, two or more cup body clamping mechanisms 2 at the same station can be called rows; of course, there are several rows of cup body clamping mechanisms 2, and several rows of flame heating mechanisms 3 should be arranged accordingly. This specification and its drawings take three rows of each station and four cup body clamping mechanisms 2 in each group as an example. Of course, the protection scope of the utility model also includes the scheme of only setting one group or one row (only one cup body clamping mechanism 2 on one station), and even includes the scheme of only setting one cup body clamping mechanism 2 on a rotating drum 10, but this structure will obviously greatly reduce the production efficiency.

[0057] At the bottom sealing station 101, the cup body clamping mechanism 2 can automatically clamp the glass tube and drive the glass tube to rotate around its axis. After the bottom sealing is completed, the cup body clamping mechanism 2 drives the cup body to rotate with the rotating drum 10 in sequence to the upper welding handle station 102, the opposite annealing station 103, and the lower unloading station 104. The cup body clamping mechanism 2 can automatically release the glass cup at the unloading station 104.

[0058] In this embodiment, at the bottom sealing station 101, the corresponding cup body clamping mechanisms 2 on the two rotating drums 10 clamp a glass tube at the same time and rotate synchronously. The flame heating mechanism 3 of the bottom sealing station 101 is located below the glass tube clamped by the cup body clamping mechanism 2. Through the cooperation between the flame heating mechanism 3 and the cup body clamping mechanism 2, a glass tube is first divided into two sections, and then the two sections of the glass tube are sealed respectively to form two glass cup bodies. Then the two rotating drums 10 respectively carry the cup body clamping mechanism 2 and the glass cup body to the welding handle station 102 above them. At the welding handle station 102, through the cooperation between the cup handle clamping mechanism 4, the cup body clamping mechanism 2 and the flame heating mechanism 3 for the welding handle, the cup handle and the bottom-sealed glass cup body can be automatically bonded together; then they are respectively transferred to the annealing station 103 and the unloading station 104. The utility model combines the steps of dividing and sealing the bottom of the glass tube, bonding the glass cup body and the cup handle, annealing the glass cup, transferring and the like, thus realizing automation and improving production efficiency.

[0059] The flame heating mechanism 3 of the bottom sealing station 101 of the present invention can be referred to in the specific setting. Figure 2 and Figure 3The flame heating mechanism 3 of the bottom sealing station 101 includes a support frame 33 fixed in the middle position of the frame 1, and three bottom sealing flame spraying tubes 31 are horizontally arranged side by side on the support frame 33 to correspond to the three rows of cup body clamping mechanisms 2 on the bottom sealing station; each bottom sealing flame spraying tube 31 is installed on the support frame 33 through a bottom sealing gas pipe 34, and the bottom end of the bottom sealing gas pipe 34 is connected to an external gas source through a gas pipe. Each bottom sealing flame spraying tube 31 is horizontally arranged and its length direction is perpendicular to the glass tube. A plurality of bottom sealing flame spraying nozzles 32 are arranged side by side along the length direction of the top of each bottom sealing flame spraying tube 31, and the flame spraying direction of each bottom sealing flame spraying nozzle 32 is vertically upward. The glass tube clamped by the cup body clamping mechanisms 2 on the two rotating drums 10 is horizontally above the bottom sealing flame spraying nozzle 32. Continue to refer to Figure 3 Next to each bottom-sealed flame-spraying tube 31, an ignition mechanism 35 is provided. The ignition mechanism 35 can be an electric ignition or a constant open flame, which are commonly used in the conventional technology. Figure 2 It can be known that a feeding mechanism 5 is arranged above the flame heating mechanism 3 of the bottom sealing station 101, and the feeding mechanism 5 includes a feeding bracket 52 and a feeding manipulator 51 corresponding to the feeding bracket 52, and the feeding manipulator 51 is higher than the feeding bracket 52 and can move up and down. The feeding bracket 52 is used to place the glass tube, and the feeding manipulator 51 is used to grab the glass tube on the feeding bracket 52, move the glass tube to the top of the flame heating mechanism 3 of the bottom sealing station, and wait for the two cup body clamping mechanisms 2 on the two rotating drums to clamp the glass tube. After the two cup body clamping mechanisms 2 clamp the glass tube, the feeding manipulator 51 rises back to the waiting position. At this time, the two cup body clamping mechanisms 2 rotate synchronously in the same direction, and the flame heating mechanism 3 of the bottom sealing station starts to spray fire, and at this time, the middle position of the glass tube is aligned with the flame generated by the flame heating mechanism 3 of the bottom sealing station.

[0060] The feeding bracket 52 can be referred to in the specific setting. Figure 2 and Figure 4 .according to Figure 2 and Figure 4It can be seen that the loading bracket 52 includes a gas pressure rod 522 whose bottom end is fixedly connected to the frame 1, and the gas pressure rod 522 is arranged tilted upward. The top of the gas pressure rod 522 is fixedly connected to a horizontal bracket 523 arranged along the width direction of the frame 1. Three receiving grooves 521 for storing glass tubes are arranged above the horizontal bracket 523 to correspond to the three rows of cup body clamping mechanisms 2 and flame heating mechanisms 3 of the bottom sealing station 101. One receiving groove 521 corresponds to one bottom sealing flame-spraying tube 31. The receiving grooves 521 are arranged in a V-shape or a U-shape, and each receiving groove 521 is connected to the horizontal bracket 523 through a vertical rod. When the pneumatic rod 522 in the utility model is in an extended state, the material receiving groove 521 is higher than the bottom sealing flame spraying tube 31, so that the flame sprayed from the bottom sealing flame spraying nozzle 32 can roast the glass tube. This position is a waiting state for loading. At this time, the residual heat of the flame of melting and bottom sealing can roast the glass tube and preheat it; when the pneumatic rod 522 is in a retracted state, the material receiving groove 521 reaches directly above the corresponding bottom sealing flame spraying tube 31, so that the loading robot 51 moving up and down can clamp the glass tube, and then the two cup body clamping mechanisms 2 of the bottom sealing station 101 respectively clamp the two ends of the glass tube to start the melting and bottom sealing operations.

[0061] The feeding manipulator 51 in the utility model can continue to refer to the specific arrangement Figure 2 .according to Figure 2 It can be seen that the feeding manipulator 51 includes a first lifting plate 511 which is located above the flame heating mechanism 3 and the feeding mechanism 5 and is arranged horizontally in the front and back. Two of the first lifting plates 511 are arranged up and down and fixedly connected. Three first two-way cylinders 514 are arranged side by side between the two first lifting plates 511. The first lifting plate 511 drives the three first two-way cylinders 514 to move up and down at the same time to correspond to the three rows of cup body clamping mechanisms 2. First clamping plates 512 are arranged on both sides of each first two-way cylinder 514. One end of the first clamping plate 512 is connected to the first two-way cylinder 514, and the other end is fixedly connected to an arc plate 513 for clamping the glass tube. A pair of arc plates 513 corresponds to a bottom-sealed flame-spraying tube 31. In the utility model, the first bidirectional cylinder 514 can drive the two arc plates 513 clamping the glass tube to move closer to or farther from each other at the same time, and the two arc plates open and close at the same time. When clamping glass tubes of different diameters, the center lines of the glass tubes are ensured to be in the same position, making it convenient for the cup body clamping mechanism 2 to accurately clamp the glass tube.

[0062] Further, in order to facilitate the up and down movement of the loading robot 51 in the vertical direction, continue to refer to Figure 2, the frame 1 is provided with a plurality of first vertical guide rails 515 penetrating the first lifting plate 511, the top of the first vertical guide rail 515 is fixedly connected with a first cylinder 516, the telescopic end of the first cylinder 516 is connected to the first lifting plate 511, and the first lifting plate 511 is driven by the first cylinder 516 to move up and down along the first vertical guide rail 515, thereby driving the loading manipulator 51 to move up and down. In this way, in addition to the clamping action, the loading manipulator 51 only has the action of moving up and down, which can make the loading position more accurate. Of course, the loading bracket 52 of the utility model can also be fixed, as long as the material receiving groove 521 of the loading bracket is higher than the flame heating mechanism 3 of the bottom sealing station and is located above it. At this time, the loading manipulator 51 needs to be set to a structure and control program that can move forward and backward and up and down.

[0063] In the present invention, the specific arrangement position and structure of the two rotating drums 10 can be referred to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 .Depend on Figure 1 It can be seen that the two rotating drums 10 are arranged symmetrically on both sides of the flame heating mechanism 3 of the bottom sealing station 101, and the structures of the two rotating drums 10 are exactly the same, except that the directions of rotation and movement are opposite. Figure 5 and Figure 6 It can be seen that the rotating drum 10 is connected to the frame 1 through the first sliding seat 13 that drives the rotating drum 10 to move left and right. In addition to being connected to the first sliding seat 13, the other end of the rotating drum 10 is also slidably connected to the first horizontal guide rail 66, and the first horizontal guide rail 66 is connected between two support frames 33 fixedly connected to the frame 1, and the rotating drum 10 is located between the two support frames 33. A plurality of cup body clamping mechanisms 2 are arranged on the cylindrical surface of the rotating drum 10, which are grouped or rowed according to the stations. In this embodiment, three rows of cup body clamping mechanisms 2 are arranged on one station, and the four cup body clamping mechanisms 2 arranged along the circumferential direction of the rotating drum 10, which correspond to the bottom sealing station 101, the welding handle station 102, the annealing station 103, and the unloading station 104, are called a group. Each cup body clamping mechanism 2 includes a three-jaw chuck 21 , which can use a three-jaw pull-back chuck commonly used in the conventional technology. The three-jaw chuck 21 can automatically shrink to clamp the glass tube and can rotate when in the bottom sealing station 101 .

[0064] according to Figure 6 , Figure 7 and Figure 8It can be seen that each three-jaw chuck 21 is connected to the rotating drum 10 through a rotating tube 22. A through hole is provided on the circumferential wall of the rotating drum 10 corresponding to the position of each three-jaw chuck 21, and a bearing 26 is fixedly arranged in the through hole. The inner ring of the bearing 26 is fixedly connected to the rotating tube 22, and the rotating tube 22 passes through the inside and outside of the rotating drum 10. The outer end of the rotating tube 22 is fixedly connected to the corresponding three-jaw chuck 21, and the inner end of the rotating tube 22 extends into the rotating drum 10 and is fixedly connected to a rotating gear 24. The rotating gear 24 installed at the inner end of the rotating tube 22 drives the rotating tube 22 and the three-jaw chuck 21 to rotate. A self-rotation drive mechanism 14 is provided on the first sliding seat 13 at a position corresponding to the bottom sealing station 101 of the rotating drum 10. The self-rotation drive mechanism 14 is provided on the first sliding seat 13 at a side close to the bottom sealing station 101. When the cup body clamping mechanism 2 rotates to the bottom sealing station 101, the rotating gear 24 in the rotating drum 10 at the corresponding bottom sealing station close to the end of the first sliding seat 13 is connected to the driving gear 141 of the self-rotation drive mechanism 14, thereby driving the three-jaw chuck 21 of the cup body clamping mechanism 2 to rotate. A transition gear 25 is meshed and connected between the two rotating gears 24 of the two adjacent cup body clamping mechanisms 2 in the same row at the same station, so that the three-jaw chucks 21 in the same row at the bottom sealing station 101 can rotate synchronously.

[0065] The above-mentioned self-rotation driving mechanism 14 can continue to refer to Figure 5 and Figure 6 . The driving gear 141 of the self-rotation driving mechanism 14 is close to the drum 10 and can mesh with the rotating gear 24 of the cup body clamping mechanism 2. The driving gear 141 is coaxially fixedly connected with the first pulley 142, and a second pulley 143 driven by a rotating motor is also installed on the first sliding seat 13, and the second pulley 143 is connected to the first pulley 142 through a transmission belt 144. When the cup body clamping mechanism 2 rotates to the bottom sealing station 101 with the drum 10, the rotating gear 24 of the cup body clamping mechanism 2 close to the first sliding seat 13 is meshed and connected with the driving gear 141 in the self-rotation driving mechanism 14, and the entire row of cup body clamping mechanisms 2 are driven to rotate in sequence through the rotating motor.

[0066] The clamping jaws of the three-jaw chuck 21 of the utility model are controlled by the control mechanism 6 so that the clamping jaws can be opened at the unloading station 104 and the bottom sealing station 101. Figure 6 , Figure 7 and Figure 8 A claw push rod 23 for opening the claws of the three-jaw chuck 21 is provided in the rotating tube 22. The claw push rod 23 (i.e., the rear pull rod in the three-jaw chuck 21) runs through each rotating tube 22 and extends into the rotating drum 10. One end of the claw push rod 23 extends out of the rotating tube 22 and corresponds to the control mechanism 6 located in the rotating drum 10.

[0067] The control mechanism 6 of this embodiment includes a camshaft 61 located in the drum 10 and arranged on the same center line as the drum 10. Cams 62 corresponding to the claw push rods 23 of each group are arranged on the circumference of the camshaft 61, and a camshaft cylinder 63 is connected to the end of the camshaft 61. The camshaft cylinder 63 drives the camshaft 61 and the cam 62 thereon to rotate. In the utility model, the camshaft 61 and the cam 62 only rotate 90° between the unloading station 104 and the bottom sealing station 101. When the cam 62 moves to the bottom sealing station 101, it will squeeze the claw push rod 23 of the three-jaw chuck 21 here outward to open the claws of the three-jaw chuck 21. As the rotating drum 10 and the three-jaw chuck 21 move toward the middle, when the claws of the three-jaw chuck 21 reach the end position of the glass tube, the cam shaft 61 rotates downward, the cam 62 leaves the bottom sealing station 101, and the cam is disengaged from the claw push rod 23. The claw push rod 23 of the three-jaw chuck 21 at the bottom sealing station 101 returns to its original position, and the claws of the three-jaw chuck 21 shrink to clamp the glass tube; after the cam 62 moves to the unloading station 104, it pushes in the claw push rod 23 located at the unloading station to open the claws of the three-jaw chuck 21, and waits for the next action at this position.

[0068] The camshaft 61 and cam 62 of the utility model rotate between the unloading station 104 and the bottom sealing station 101, which is realized by the camshaft cylinder 63 installed at one end of the camshaft 61. The outer end of the camshaft 61 of the utility model is installed on the support rod 64, and the camshaft cylinder 63 is vertically arranged on one side of the support rod 64. The upper part of the camshaft cylinder 63 is hinged with the camshaft 61 through the arc rod 65. The above-mentioned support rod 64 is slidably connected to the first horizontal guide rail 66 between the two support frames 33 connected to the frame 1. The rotary drum 10 of the utility model and its internal camshaft 61 and other components can slide left and right in the horizontal direction under the drive of the first sliding seat 13 and the support of the support rod 64.

[0069] When the cup body clamping mechanism 2 of the utility model reaches the welding handle station 102, the direction and position of the clamping claw of the three-jaw chuck 21 are fixed, and the utility model has a positioning device at the welding handle station 102. The positioning device includes a triangular positioning piece 27 fixed on the cup body clamping mechanism 2, and the triangular positioning piece 27 is fixed on the rotating tube 22 of the cup body clamping mechanism 2 near one end of the first sliding seat 13, located at the lower part of the three-jaw chuck 21, and coaxially fixedly connected with the three-jaw chuck 21; the positioning device also includes a positioning mechanism 11 at the welding handle station 102, corresponding to the triangular positioning piece 27, and the positioning mechanism includes an arc-shaped positioning plate 112 supported by a spring rod 111, and the spring rod 111 is fixedly connected to the first sliding seat 13. This arc-shaped positioning plate 112 is located outside the circumference of the rotating drum 10, that is, above the rotating drum 10, and corresponds to the triangular positioning plate 27. Its curvature corresponds to the circumference of the rotating drum 10. When the cup body clamping mechanism 2 rotates to the welding handle station 102 driven by the rotating drum, the triangular positioning plate 27 hits the arc-shaped positioning plate 112, driving the cup body clamping mechanism 2 to rotate, so that one side of the triangular positioning plate 27 and the end face of the arc-shaped positioning plate 112 finally stably contact each other, forming a directional positioning of the claws of the cup body clamping mechanism 2. The triangular positioning plate 27 of the utility model adopts a triangle, and the three sides of the triangle correspond to the three claws of the three-claw chuck 21 respectively. After positioning, it is ensured that the glass cup handle will not touch the claws during welding; the starting end of the arc-shaped positioning plate 112 is also provided with a guide angle 113, which is convenient for the triangular positioning plate 27 to enter.

[0070] In order to facilitate the rotation of the drum 10 in the present invention, a stepping drive mechanism 12 for driving the drum 10 to rotate is provided on the first sliding seat 13. The stepping drive mechanism 12 can be further referred to in the specific arrangement.

Continue to refer to Fig.11A gap adjustment block 419 for adjusting the gap between the two clamping plates 412 may be disposed inside the second clamping plate 421. The adjustment block 419 is connected to the second clamping plate 412 via an adjustment bolt 4191 to accommodate handles of different widths or diameters. A limiting rod 417 for limiting the holding block 416 may be disposed on the side of the movable pin 415 on which the holding block 416 is installed, so that a certain opening can be formed between the holding block 416 and the positioning plate 414 in a natural state, making it convenient for the cup handle to be placed. The cup handle clamping mechanism 4 of the utility model also includes a height adjustment mechanism for adjusting the height of the cup handle manipulator 41.

[0075] The flame heating mechanism 3 of the welding handle station 102 in the present invention can be referred to in the specific setting. Fig.12 and Fig.13The flame heating mechanism 3 of the welding handle station 102 includes a flame tube 71 provided with a flame nozzle 711. The flame spraying direction of the flame nozzle 711 is toward the corresponding cup handle clamping mechanism 4 and the cup body clamping mechanism 2, and the flame sprayed by the flame nozzle 711 is respectively toward the end of the cup handle and the welding part of the cup body. When welding a C-shaped cup handle, the flame nozzle 711 should be provided with two corresponding pairs of left and right. The distance between the two pairs of flame nozzles 711 corresponds to the distance between the upper and lower welding points of the C-shaped cup handle; continue to refer to Fig.12 and Fig.13 The flame-spraying tube 71 is arranged on a horizontally arranged gas supply main pipe 716, and the number of the flame-spraying tubes 71 connected to the gas supply main pipe 716 is the same as the number of the cup handle manipulators 41 and corresponds one to one.

At this time, the flame nozzle 711 sprays out a low-pressure normal burning flame; when the flame heating mechanism 3 of the welding handle station 102 is located between the cup body clamping mechanism 2 and the cup handle clamping mechanism 4 of the welding handle station 102, the solenoid valve 717 is opened. At this time, high-pressure gas and high-pressure oxygen are supplied to the gas supply main pipe 716 and the flamethrower 71 through the gas pipe 714 and the oxygen pipe 713. At this time, the flame nozzle 711 sprays out a high-pressure molten flame, thereby melting the positions of the cup handle and the cup body welding points.

The third sliding seat 81 is slidably connected to the frame 1 and driven by a power machine. One side of the third sliding seat 81 is fixedly connected with three flame hoods 82 corresponding to the three cup body clamping mechanisms 2. The flame hoods 82 can move horizontally relative to the cup body clamping mechanism 2 on the annealing station 103 under the drive of the third sliding seat 81 and cover the glass cups. Each flame hood 82 can spray flames into the inside, so that the glass cups in the flame hood 82 are kept warm and annealed.

[0079] After annealing, the glass is rotated to the unloading station 104. At this time, the cam 62 on the cam shaft 61 is at the bottom, pressing the jaw push rod 23 of the three-jaw chuck 21 entering this station, so that the jaws of the three-jaw chuck are opened, and the glass falls into the transportation mechanism 9 below the unloading station 104. The transportation mechanism 9 can be a conveyor belt or a transfer vehicle, etc. After receiving the workpiece, it transports the workpiece to the next process. During the transportation process, the temperature of the glass can be reduced to room temperature.

[0080] The working principle of the equipment for producing glass cups of the utility model is as follows: in the standby state, the pneumatic rod 522 of the loading bracket 52 is in an extended state, the receiving trough 521 is in a high position, and at the same time, the loading robot 51 is located at the highest point above the flame heating mechanism 3 of the bottom sealing station 101, the rotating drum 10 is away from the flame heating mechanism 3 of the bottom sealing station 101, and the cup handle clamping mechanism 4 and each flame heating mechanism 3 are away from the rotating drum 10.

[0081] During the working process, a glass tube is placed in each receiving groove 521, and then the pneumatic rod 522 is retracted. At this time, the receiving groove 521 moves to a position aligned with the upper feeding robot 51, and then the feeding robot 51 moves downward, opens, and clamps the glass tube; then the feeding robot 51 clamps the glass tube and moves upward slightly, the pneumatic rod 522 returns to the extended state, and the feeding robot 51 clamps the glass tube and descends again until the glass tube and the cup body clamping mechanism 2 of the bottom sealing station 101 are located on the same axis, and the two rotating drums 10 with the cup body clamping mechanism 2 are The two three-jaw chucks 21 at the bottom sealing station 101 respectively move inward, at this time the camshaft 61 rotates, and the cam 62 presses against the claw push rod 23 of the three-jaw chuck 21 at the bottom sealing station 101 to open the claw until the claw of the three-jaw chuck 21 coincides with one end of the glass tube, and the camshaft 61 rotates back to the unloading station 104, and the two three-jaw chucks 21 at the bottom sealing station 101 grab the two ends of the glass tube, and the loading robot 51 releases the glass tube and rises to the waiting position. At this point, the loading is completed, and then the multi-row workpiece clamping mechanism 2 of the bottom sealing station 101 is driven by the rotation drive mechanism 14 to start rotation.

[0082] Then, the bottom sealing flame nozzle 32 is ignited, and the flame burns the middle position of the glass tube. When the glass tube is burned to a molten state, the two rotating drums 10 move away from the flame heating mechanism 3 respectively, and divide the glass tube into two sections. Then, the two rotating drums 10 move toward the bottom sealing flame nozzle 32 again, so that the flame sprayed from the bottom sealing flame nozzle 32 completes the bottom sealing of the two sections of the glass tube. Then, the two rotating drums 10 move to both sides respectively and rotate in steps to turn the glass cup body with the completed bottom sealing to the welding handle station 102 just above.

[0083] During the process of melting the glass tube and sealing the bottom, the glass tube has been placed on the feeding support again, and the flames of melting and sealing the bottom preheat the glass tube placed on the material receiving groove 521. After the feeding is completed, the feeding is performed again at the bottom sealing station 101.

[0084] At the welding handle station 102, the glass cup body is located directly above the rotating drum 10, and the glass cup handle is pre-placed in the handle clamping groove 418 of the handle manipulator 41, and the second sliding seat 42 drives the handle manipulator 41 and the glass cup handle to move toward the cup body, and at the same time, the lifting seat 73 drives the flame nozzle 711 to move downward to between the glass cup handle and the glass cup body, and then the flame nozzle 711 sprays fire to burn the glass cup handle and the glass cup body respectively until they are melted, and the flame nozzle 711 moves upward away from the welding handle station 102, and the glass cup handle continues to move toward the corresponding glass cup body until the position where the glass cup handle is burned and the position where the glass cup body is burned are tightly fitted together to form a complete glass cup, and then the handle manipulator 41 releases the cup handle and the second sliding seat 42 moves away from the glass cup and returns to its original position.

[0085] When the work of each station is completed, the rotating drum 10 rotates again, and the glass cup after the welding handle is transferred to the annealing station 103. The flame heating mechanism 3 of the annealing station 103 moves toward the cup body clamping mechanism 2 of the annealing station 103 until the flame hood 82 is sleeved on the glass cup of the annealing station 103, and then the flame is sprayed from the flame hood 82. The temperature of the flame is lower than the melting temperature of the glass, so that the glass cup is kept warm for annealing, and cracks are prevented from being generated by excessive cooling of the glass cup.

[0086] When the work of each station is completed, the drum 10 rotates again, driving the cup body clamping mechanism 2 and the glass cup to rotate to the unloading station 104. At this time, the cam 62 on the camshaft is just in this position. The cam 62 will squeeze the claw push rod 23 on the three-claw chuck 21, so that the three-claw chuck 21 is loosened, and the glass cup falls onto the transport mechanism 9. At this point, one glass tube is made into two glasses. The drum 10 with three cup body clamping mechanisms 2 is set on one station (in one row) designed in this embodiment. Each time the material is loaded and rotated once, six glasses are produced.

Thus, the corresponding first sliding seat 13 is driven to move on the frame 1 along the second horizontal guide rail 134 by the double-headed motor 132 and the first threaded rod 133.

[0089] In the present invention, in order to facilitate the movement of the third sliding seat 81, continue to refer to Figure 1 The third sliding seat 81 is slidably mounted on a plurality of fourth horizontal guide rails 84 parallel to the left and right directions of the frame 1, and the fifth threaded rod 83 driven by the second driving motor is threadedly connected to the third sliding seat 81. Thus, the third sliding seat 81 is driven by the second driving motor and the third threaded rod 75 to move horizontally left and right on the frame 1 along the fourth horizontal guide rails 84.

[0090] Embodiment 3

[0091] This embodiment is based on the first embodiment. In order to make the glass cup more evenly heated in the annealing station 103, a self-rotation drive mechanism can also be set on the side of the first sliding seat 13 close to the annealing station 103. When the rotating drum 10 drives the cup body clamping mechanism 2 to rotate to the annealing station 103, the rotating gear 24 of the cup body clamping mechanism 2 close to the first sliding seat 13 is meshed and linked with the driving gear in the self-rotation drive mechanism, so that the three-jaw chuck 21 of the cup body clamping mechanism 2 of the annealing station 103 is driven to rotate by the self-rotation drive mechanism, so that the glass cup is heated more evenly during annealing.
