Description

Technical Field

[0001] The present invention belongs to the technical field of glass manufacturing, and particularly relates to a multi-station centrifuge with a cover plate. Background Art

[0002] In the manufacturing process of rotary glass utensils, it is necessary to take out the molten glass solution from the furnace, place it in the corresponding mold for centrifugal forming, and then remove and anneal the formed workpiece. All these existing processes require manual operation, resulting in high labor intensity, low processing efficiency. Moreover, during the production process, multiple workers can only process one workpiece at a time per unit time, which also limits the processing efficiency. In addition, in the existing processing process, due to the cumbersome installation and disassembly of the mold, only one type of workpiece can be processed separately during the processing. After completing the processing of the previous type of workpiece, another mold needs to be replaced to process the next type of workpiece. Two or more different types of workpieces cannot be produced simultaneously during the processing, unable to meet the production requirements. Summary of the Invention

[0003] (1) Invention Objectives

[0004] In order to overcome the above deficiencies, the objective of the present invention is to provide a multi-station centrifuge with a cover plate to solve the technical problems of manual operation required during the manufacturing of existing glass workpieces, low processing efficiency, high labor intensity, high labor cost, and only one type of workpiece can be processed separately during the processing, unable to meet the simultaneous processing of multiple different types of workpieces.

[0005] (2) Technical Solutions

[0006] To achieve the above objective, the technical solutions provided by the present application are as follows:

[0007] A multi-station centrifuge with a cover plate, comprising:

[0008] A mold indexing mechanism, which is rotatably arranged, and a plurality of molds of the same type or different types for containing processing raw materials are circumferentially arranged on its edge, capable of driving the plurality of molds of the same type or different types containing processing raw materials to rotate to different processing stations for processing;

[0009] A cover plate power mechanism, which is arranged at the forming station. At least one cover plate matching all molds of the same type or a plurality of cover plates respectively matching different types of molds are arranged on the cover plate power mechanism, used for driving the cover plate of the same type to move downward to cover the corresponding mold after the mold is filled with processing raw materials;

[0010] A rotary centrifugal mechanism is arranged on the forming station or on the die indexing mechanism, and is drivingly connected to the die, and is used to drive the die covered with the cover plate to rotate centrifugally so that the processing raw material is attached to the inner wall of the die, and a workpiece matching the shape of the die is formed.

[0011] In this application, by setting a die indexing mechanism, a cover plate power mechanism and a rotary centrifugal mechanism, the mechanisms cooperate with each other. Specifically, when it is necessary to batch-produce workpieces of the same type, a plurality of dies of the same type are arranged on the die indexing mechanism, and then a cover plate matching all die types is arranged on the cover plate power mechanism. After the die is filled with the processing raw material, the cover plate power mechanism drives the cover plate matching the die type to move downward to cover the die, and then the rotary centrifugal mechanism drives the die to rotate for centrifugal processing, so as to batch-produce workpieces of the same type; when it is necessary to batch-produce workpieces of different types, a plurality of different types of dies can be arranged on the die indexing mechanism, and a plurality of cover plates that are respectively and mutually matched with the dies are arranged on the cover plate power mechanism. After the die of the predetermined type is filled with the processing raw material, the cover plate power mechanism can drive the cover plate that is mutually matched with the predetermined die type to cover the die, and then the rotary centrifugal mechanism drives the die covered with the cover plate to rotate for centrifugal processing, so as to batch-produce workpieces of different types. The entire centrifugal processing process is fully mechanized and does not require manual operation, improving the processing efficiency and reducing the labor intensity.

[0012] In some embodiments, the plurality of dies are dies of the same type. The cover plate power mechanism includes: a first cover plate driving device arranged on the forming station, and a cover plate matching all die types is rotatably connected to the driving end thereof, and can successively drive the cover plate to move downward to cover the die rotated to the forming station. Since the types of the dies are the same, only one first cover plate driving device needs to be arranged on the forming station, and a cover plate that is matched with all die types is connected to the first cover plate driving device. During processing, when the dies are successively moved to the forming station, the first cover plate driving device successively drives the cover plate to move downward and successively cover the dies rotated to the forming station, and the dies covered with the cover plates can be subjected to centrifugal forming processing. This embodiment can batch-produce workpieces of the same kind.

[0013] In some embodiments, the multiple molds are of different types. The cover plate power mechanism includes: a first cover plate indexing disc, on which a plurality of second cover plate driving devices are circumferentially arranged. A cover plate respectively matching the type of one mold is rotatably arranged on the driving end of each second cover plate driving device. Since the types of the molds are different, a plurality of different types of cover plates need to be provided to cooperate with different types of molds. During processing, the rotation speed of the first cover plate indexing disc cooperates with the mold indexing mechanism. While the mold indexing mechanism drives a predetermined type of mold to rotate to the molding station, the first cover plate indexing disc drives the cover plate matching the type of this mold to synchronously rotate to the molding station. Then, the second cover plate driving device drives this cover plate to move downward to cover the mold. This embodiment can process different kinds of workpieces simultaneously to meet different production requirements.

[0014] In some embodiments, the cover plate power mechanism includes:

[0015] A second cover plate indexing disc, on which a plurality of mounting rods are circumferentially penetrated. A cover plate is arranged on each mounting rod. A reset member is also sleeved on each mounting rod. One end of the reset member is connected to the mounting rod, and the other end is connected to the second cover plate indexing disc;

[0016] A third cover plate driving device, arranged at the molding station and above the second cover plate indexing disc, for downwardly abutting and connecting the mounting rod of the corresponding cover plate when the cover plate rotates to the molding station, so that the cover plate moves downward to cover the mold of the same type;

[0017] Since the types of the molds are different, a plurality of different types of cover plates need to be provided to cooperate with different types of molds. During processing, the rotation speed of the second cover plate indexing disc cooperates with the mold indexing mechanism. While the mold indexing mechanism drives a predetermined type of mold to rotate to the molding station, the second cover plate indexing disc drives the cover plate matching the type of this mold to synchronously rotate to the molding station. Then, the third cover plate driving device abuts and connects the mounting rod of this cover plate, causing the reset member to be compressed and shortened, driving this cover plate to descend and cover the predetermined mold. After the centrifugal molding processing of the processing raw material is completed, when the third cover plate driving device moves upward and disengages from the mounting rod, the reset member drives the mounting rod to move upward and reset, and the cover plate opens. In this way, only one driving device is needed to drive a plurality of different types of cover plates to move downward for covering, which can save the manufacturing cost of the equipment.

[0018] In some embodiments, the mold indexing mechanism includes: a mold indexing disc, on which a plurality of molds of the same type or a plurality of different types are circumferentially arranged, for driving the molds to rotate one by one to the molding station for the cover plate to cover. At the position corresponding to each mold on the mold indexing disc, there is a rotating seat rotatably connected to the mold indexing disc for driving the mold to rotate self - rotatably for centrifugal processing.

[0019] In some embodiments, the rotary centrifugal mechanism includes: a connector assembly disposed at the molding station and capable of moving up and down and rotating to connect or disconnect from the bottom of the mold at the molding station; a first mold driving device drivingly connected to the connector assembly for driving the connector assembly to rotate so as to make the mold rotate on its own axis. By providing the connector assembly to connect with the mold moved to the molding station, and then driving the mold to rotate through the first mold driving device for centrifugal processing. After the centrifugal processing of the previous workpiece is completed, the connector assembly disconnects from the mold of the previous workpiece and then connects with the next mold containing the processing raw material, and then performs centrifugal processing on the processing raw material in the next mold. In this way, only one first mold driving device is needed to drive all the molds to rotate and perform centrifugal forming processing on the processing raw material in the molds, which can save the manufacturing cost of the equipment.

[0020] In some embodiments, the rotary centrifugal mechanism includes: a plurality of second mold driving devices disposed on the mold indexing mechanism and each second mold driving device is respectively drivingly connected to the bottom of a mold for driving the mold to rotate on its own axis. By providing a second mold driving device at the bottom of each mold, each second mold driving device can independently drive the corresponding mold to rotate. When the mold containing the processing raw material rotates to the next station, the corresponding second mold driving device can be immediately started to perform centrifugal processing on the processing raw material. When the mold rotates to the next station, the centrifugal forming processing is just completed. In this way, there is no need to additionally set up a molding station to wait for the processing raw material to perform centrifugal forming processing at the molding station, which can shorten the processing time and improve the efficiency.

[0029] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the detailed implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0030] A multi-station centrifuge with a cover plate provided by the present invention includes:

[0031] The mould indexing mechanism 1 is rotatably arranged, and a plurality of moulds 4 of the same type or a plurality of different types for containing processing raw materials are circumferentially arranged on its edge, and can drive the plurality of moulds 4 containing processing raw materials to rotate to different processing stations for processing;

[0032] The cover plate power mechanism 2 is arranged at the forming station. At least one cover plate matching the type of all moulds 4 of the same type or a plurality of cover plates 5 respectively matching the types of different moulds 4 are arranged on the cover plate power mechanism 2, and are used to drive the cover plates 5 of the same type to move downward to cover the corresponding moulds 4 after the moulds 4 contain processing raw materials;

[0033] The rotary centrifugal mechanism 3 is arranged at the forming station or on the mould indexing mechanism 1, and is drivingly connected to the mould 4, and is used to drive the mould 4 covered with the cover plate 5 to rotate centrifugally so that the processing raw materials are attached to the inner wall of the mould 4 to form a workpiece matching the shape of the mould 4.

[0034] Specifically, different processing stations are arranged around the die indexing mechanism 1, and corresponding processing equipment is arranged at different processing stations. For example, a feeding device can be arranged at the first processing station to convey the processing raw materials to the corresponding die 4. The second processing station is a forming station, where a rotary centrifugal mechanism 3 is arranged to perform centrifugal processing on the processing raw materials to form a shape matching the die 4. The third processing station is a cooling station to cool the formed workpiece, and the fourth processing station is a blanking station to blank the workpiece. The die indexing mechanism 1 drives the die 4 to rotate one by one to the corresponding processing stations for feeding, forming, cooling, and blanking.

[0035] Specifically, the centrifuge of the present application includes two different embodiments:

[0036] Please refer to Figure 1 , the first embodiment:

[0037] All the dies 4 on the die indexing mechanism 1 are of the same type. The cover plate power mechanism 2 is arranged at the forming station and above the die indexing mechanism 1. The cover plate power mechanism 2 is arranged to move vertically up and down. A cover plate 5 is connected to the cover plate power mechanism 2, and the cover plate 5 can match all the dies 4.

[0038] Specifically, during processing, when the die indexing mechanism 1 drives the die 4 into the forming station, the cover plate power mechanism 2 drives the cover plate 5 to move downward to cover the die 4, and then the rotary centrifugal mechanism 3 drives the die 4 to rotate self - centrically for centrifugal processing. This embodiment can mass - produce multiple workpieces of the same type.

[0039] Specifically, in the first embodiment, the cover plate power mechanism 2 includes: a first cover plate driving device 201. A cover plate 5 is rotatably arranged at the driving end of the first cover plate driving device 201. When the die indexing mechanism 1 drives the die 4 to rotate to the forming station, the first cover plate driving device 201 drives the cover plate 5 to move downward to cover the die 4.

[0040] Specifically, in the first embodiment, the die indexing mechanism 1 includes: a die indexing plate 101 and a die indexing plate driving device 102. A plurality of dies 4 of the same type are circumferentially arranged on the die indexing plate 101;

[0041] Specifically, in the first embodiment, the rotary centrifugal mechanism 3 can be arranged at the forming station. After the die 4 rotates to the forming station, the rotary centrifugal mechanism 3 drives the die 4 to rotate. Or, the rotary centrifugal mechanism 3 can be arranged on the die indexing mechanism 1 and is drivingly connected to the die 4. The rotary centrifugal mechanism 3 can rotate synchronously with the die indexing mechanism 1. When the die 4 covers the cover plate 5, the rotary centrifugal mechanism 3 can immediately drive the die 4 to rotate for centrifugal forming processing.

[0042] Please refer to Figure 2 , the second embodiment:

[0043] The multiple types of molds 4 on the mold indexing mechanism 1 are different. The cover plate power mechanism 2 can rotate circumferentially and can be vertically moved up and down. A plurality of cover plates 5 are arranged on the cover plate power mechanism 2. Each cover plate 5 respectively matches with the mold 4 on the mold indexing mechanism 1 one by one. The rotation speed of the cover plate power mechanism 2 matches that of the mold indexing mechanism 1. When the mold indexing mechanism 1 drives different types of molds 4 to rotate one by one to the forming station, the cover plate power mechanism 2 drives the cover plate 5 of the same type as the mold 4 to rotate to the forming station at the same time. Then the cover plate power mechanism 2 drives the cover plate 5 to move downward to cover the mold 4. Then the rotary centrifugal mechanism 3 drives the mold 4 to perform rotary centrifugal processing. This embodiment can process multiple different types of workpieces at the same time;

[0044] Specifically, in the second embodiment, the mold indexing mechanism 1 includes: a mold indexing plate 101 and a mold indexing plate driving device 102 for driving the mold indexing plate 101 to rotate circumferentially. A plurality of molds 4 of the same type are circumferentially arranged on the mold indexing plate 101.

[0045] Specifically, in the second embodiment, the cover plate power mechanism 2 has two different structures;

[0046] The first structure:

[0047] The cover plate power mechanism 2 includes: a first cover plate indexing plate, on which a second cover plate driving device with the same number as the cover plates 5 is circumferentially arranged. A cover plate 5 is rotatably arranged on each second cover plate driving device. The second cover plate driving device can drive the corresponding cover plate 5 to move downward to cover the mold 4 or move upward to disengage from the mold 4; Specifically, the first cover plate indexing plate is connected to the first cover plate indexing plate driving device. The first cover plate indexing plate driving device drives the first cover plate indexing plate to rotate circumferentially. The second cover plate driving device is a cylinder. The driving end of each cylinder is connected with a cover plate 5 through a rotating part such as a bearing. During operation, the driving shaft of the cylinder extends downward, driving the cover plate 5 to move downward to cover the mold 4. When the rotary centrifugal mechanism 3 drives the mold 4 to rotate, the cover plate 5 rotates synchronously with the mold 4. After the workpiece is formed and processed, the driving shaft of the cylinder moves upward, driving the cover plate 5 to move upward to disengage from the mold 4.

[0048] The second structure:

[0049] The cover plate power mechanism 2 includes:

[0050] Please refer to Figure 2 and Figure 6, a second cover plate indexing disk 202, on which a plurality of mounting rods 206 are circumferentially penetrated. One cover plate 5 is provided on each mounting rod 206. A reset member 207 is also sleeved on each mounting rod 206. One end of the reset member 207 is connected to the mounting rod 206, and the other end is connected to the second cover plate indexing disk 202;

[0051] A third cover plate driving device 204, which is arranged at the forming station and above the second cover plate indexing disk 202, is used to downwardly abut and connect the mounting rod 206 connecting the cover plate 5 when the cover plate 5 rotates to the forming station, so that the cover plate 5 moves downward to cover the same type of mold 4;

[0052] More specifically, the second cover plate indexing disk 202 is connected to a second cover plate indexing disk driving device 203. The second cover plate indexing disk driving device 203 drives the second cover plate indexing disk 202 to rotate circumferentially. The reset member 207 can be a spring. The third cover plate driving device 204 is a cylinder. A plurality of through holes are opened on the second cover plate indexing disk 202. The springs are arranged above the second cover plate indexing disk 202 and correspond to each through hole. A mounting rod 206 is sleeved in the middle of each spring. The mounting rod 206 is connected to the cover plate 5 through a rotatable mounting seat 205. Specifically, the cover plate 5 on the cover plate power mechanism 2 is connected and installed through the rotatable mounting seat 205.

[0053] When the cover plate is closed, the driving shaft of the third cover plate driving device 204 moves downward, compressing the spring. The spring contracts, the height of the mounting rod 206 decreases, and the cover plate 5 covers the mold 4. The driving shaft of the third cover plate driving device 204 continuously abuts against the mounting rod 206. When the rotary centrifugal mechanism 3 drives the mold 4 to rotate, the cover plate 5 rotates synchronously with the mold 4. After the workpiece is formed, the driving shaft of the third cover plate driving device 204 moves upward, the spring expands, driving the mounting rod 206 to move upward, and the cover plate 5 is separated from the mold 4.

[0056] Please refer to Figure 3 and Figure 4, specifically, a plurality of rotating seats 103 are circumferentially arranged on the mold indexing plate 101. Each rotating seat 103 is rotatably connected to the mold indexing plate 101, and a mold 4 is installed on each rotating seat 103. When the rotating seat 103 is driven to rotate, the rotating seat 103 drives the mold 4 to rotate self - sufficiently;

The second connecting portion 305 is connected to the rotating seat 103. More specifically, the first connecting portion 304 and the first mold driving device 301 are installed on the connecting plate 302. The lifting driving device 303 is connected to the connecting plate 302. The lifting driving device 303 drives the first connecting portion 304 and the first mold driving device 301 to move upward synchronously through the connecting plate 302. The first connecting portion 304 is connected with a fitting portion 3041. The driving end 3011 of the first mold driving device is connected to the fitting portion 3041 through a belt, driving the fitting portion 3041 to rotate, thereby driving the first connecting portion 304 to rotate. The second connecting portion 305 is connected to the bottom of the rotating seat 103. During centrifugal processing, when the mold indexing mechanism 1 drives the mold 4 to rotate to the forming station, the first connecting portion 304 moves upward under the drive of the lifting driving device 303 and is connected to the second connecting portion 305. Then the first mold driving device 301 is started, driving the first connecting portion 304 to rotate, and driving the second connecting portion 305 and the mold 4 to rotate through the first connecting portion 304.

[0061] Preferably, tooth portions that can mesh with each other are respectively arranged on the connecting surfaces of the first and second connecting portions 305. By providing the tooth portions to connect the two connecting portions, relative sliding during the rotation of the two connecting portions can be avoided, ensuring the centrifugal effect.
