Pottery drawing device

Abstract

This invention pertains to ceramic equipment and discloses a ceramic throwing device. When throwing square ceramic blanks using existing throwing machines, the turntable needs to be manually rotated. However, manual rotation makes it difficult to control the rotation angle, and because there is no turntable to lock it in place, the turntable easily rotates during trimming, affecting the throwing effect. The technical solution of this invention includes a housing and a control box. A turntable is installed on the top of the housing, and a retaining ring is fixedly installed on the top surface of the housing. The bottom surface of the turntable is rotatably connected to the upper end of a movable tube, which passes through the top of the housing and is rotatably connected. Compared with existing throwing devices, this invention can lock the turntable when the motor is not working, preventing it from rotating arbitrarily. Furthermore, a limiting device limits the rotation angle of the movable tube, thus ensuring a fixed rotation angle of the turntable by rotating the handwheel. This facilitates the processing of polygonal ceramic blanks, and the rotation angle is more precise, making the processing and manufacturing of polygonal ceramic blanks easier.

Description

Technical Field

[0001] This invention pertains to ceramic equipment, specifically to a ceramic throwing device. Background Technology

[0002] Ceramic art is an art form that combines my country's traditional ancient culture with modern art. Throwing is an extremely common method of ceramic forming, so ceramic throwing machines have become common ceramic throwing machinery.

[0003] The turntable of existing pottery throwing machines is driven to rotate directly or indirectly by a motor. When the motor is not working, the turntable is not locked. When throwing square pottery blanks, the turntable needs to be rotated manually. However, it is difficult to control the rotation angle when rotating manually. Furthermore, since there is no turntable to lock it, the turntable is easy to rotate when trimming, which affects the throwing effect. Summary of the Invention

[0004] To address the shortcomings of the prior art, the present invention aims to provide a pottery throwing device. This device can lock the turntable when the motor is not in operation, preventing the turntable from rotating arbitrarily. Furthermore, a limiting device limits the rotation angle of the movable tube, thereby ensuring that the turntable rotates at a constant angle by rotating the handwheel. This facilitates the processing of polygonal pottery blanks, and the rotation angle is more precise, thus facilitating the processing and manufacturing of polygonal pottery blanks.

[0005] The technical solution adopted by this ceramic throwing device to solve its technical problems is as follows:

[0006] A pottery throwing device is provided, including a housing and a control box. A turntable is installed on the top of the housing, and a retaining ring is fixedly installed on the top surface of the housing. The bottom surface of the turntable is rotatably connected to the upper end of a movable tube, which passes through the top of the housing and is rotatably connected. A handwheel is fixedly installed on the outer periphery of the movable tube, located above the housing. The bottom surface of the turntable is fixedly connected to the upper end of a rotating shaft, which passes through the movable tube. A torsion spring is installed between the movable tube and the top surface of the inner wall of the housing. The lower end of the rotating shaft is connected to the bottom surface of the inner wall of the housing via a one-way bearing. A motor is installed inside the housing, and the inner wall of the motor is connected to one end of a worm gear via a one-way bearing. A worm wheel is fixedly installed on the rotating shaft, and the worm gear meshes with the worm. A gear transmission structure is provided between the movable tube and the worm. A control device is installed in the control box, and the motor circuit is connected to the control device. A limit device is provided on the movable tube to control the rotation angle of the movable tube.

[0007] Furthermore, the control device comprises a spring rod, a horizontal first rack, a roller, a first gear, a vertical movable rod, a horizontal second rack, a second gear, a push switch, a control knob, and a control plate. The top surface of the control box has a through slot, and the roller is housed within the control box at the through slot. The first gear is coaxially mounted with the roller and meshes with the first rack. A first limiting slide block structure is provided between the roller's mounting shaft and the control box. The lower end of the spring rod is fixedly connected to the bottom surface of the control box, and the upper end of the spring rod is connected to the first rack. A second limiting slide groove slider structure is provided between the bottom of the bars. The movable rod is provided on one side of the first rack. A third limiting slide groove slider structure is provided at one end of the first rack and one side of the movable rod. One end of the second rack is fixedly connected to the movable rod. The second rack meshes with the second gear. The second gear is provided on the rotation shaft of the control knob. The control knob is fixedly installed in the control box. The push switch is fixedly installed on the bottom surface of the control box. The push switch is located directly below the roller. The motor is electrically connected to the control board. Both the push switch and the control knob are electrically connected to the control board.

[0008] Furthermore, an anti-slip pad is fixedly installed on the bottom surface of the outer wall of the control box.

[0009] Furthermore, the control box has a recessed structure at the through slot.

[0010] Furthermore, the limiting device consists of a control groove and a screw. The control groove is opened on the outer periphery of the movable tube. The control groove is an arc-shaped groove. The depth of the control groove from one end to the other end is from deep to shallow. One end of the screw is located in the control groove and passes through the housing and is threaded.

[0011] Furthermore, a handle is fixedly installed at the other end of the screw.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. An example of a pottery throwing device of the present invention, wherein when the motor is turned on, the output shaft of the motor rotates in the forward direction, which drives the rotating shaft to rotate in the forward direction through the worm and worm wheel. The rotation of the rotating shaft drives the turntable to rotate, and the pottery is thrown through the rotating turntable. When the motor is turned off, the limiting function between the worm and worm wheel can lock the rotating shaft, thereby preventing the turntable from rotating. Rotating the handwheel in the forward direction drives the movable tube to rotate in the forward direction. The rotation of the movable tube drives the worm to rotate through the gear transmission device, which in turn drives the turntable to rotate by a certain angle. The limiting device can limit the rotation angle of the movable tube. After rotation, the movable tube can rotate in the opposite direction and reset under the action of the torsion spring. At this time, the worm gear will not be driven to rotate through the gear transmission device. Compared with the existing pottery pulling device, the turntable can be locked when the motor is not working to prevent the turntable from rotating randomly. Secondly, the limiting device limits the rotation angle of the movable tube, so that the turntable can be rotated at a certain angle by rotating the handwheel, which facilitates the processing of polygonal ceramic blanks and the rotation angle is more precise, thus facilitating the processing and manufacturing of polygonal ceramic blanks.

[0014] 2. An example of the pottery throwing device of the present invention involves placing one's foot on the top surface of the control box and pressing down on the rollers with the toes. The rollers contact a push-button switch, which controls the motor's start and stop via a control panel. When the motor starts, the movement of the foot causes the rollers to rotate. The rotation of the rollers moves the first rack, which in turn moves the second rack via a movable plate. The movement of the second rack, in turn, drives the control knob via a second gear, thereby controlling the output shaft speed of the motor via the control panel. Compared with existing controllers that control the switch by foot, this control device controls the motor's on / off state and the output shaft speed separately through the up-and-down movement and rotation of the rollers, both of which are accomplished by the foot. During use, there is no need for continuous foot pressure, making it more convenient. Furthermore, it prevents changes in the rotation speed of the turntable due to variations in foot pressure, thus avoiding affecting the processing of the pottery blank.

[0015] 3. In the pottery throwing device of the present invention, the anti-slip pad can increase the friction between the control box and the placement surface, and prevent the control box from sliding when the roller is driven to rotate by the foot, making it more convenient to use.

[0016] 4. In an example of the present invention, a pottery throwing device is provided with a recessed structure in the through slot of the control box. This structure facilitates stepping down on the roller and makes it easier to rotate the roller by moving the foot, making it more convenient to use.

[0017] 5. An example of the present invention is a pottery throwing device. By rotating the screw, the screw can be moved left and right, thereby adjusting the length of the screw within the limiting groove, thus limiting the rotation of the movable tube and controlling the limiting angle.

[0018] 6. An example of the present invention is a pottery throwing device, in which the handle can provide a point of force, thereby facilitating the rotation of the screw and making it easy to use. Attached Figure Description

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 and 2As shown, a pottery throwing device includes a housing 1 and a control box 2. A turntable 3 is installed on the top of the housing 1, and a retaining ring 4 is fixedly installed on the top surface of the housing 1. The bottom surface of the turntable 3 is rotatably connected to the upper end of a movable tube 5, which passes through the top of the housing 1 and is rotatably connected. A handwheel 6 is fixedly installed on the outer periphery of the movable tube 5, located above the housing 1. The bottom surface of the turntable 3 is fixedly connected to the upper end of a rotating shaft 7, which passes through the movable tube 5. A torsion spring is installed between the movable tube 5 and the top surface of the inner wall of the housing 1. The lower end of the rotating shaft 7 is connected to the bottom surface of the inner wall of the housing 1 via a one-way bearing. A motor 8 is installed inside the housing 1, and the inner wall of the motor 8 is connected to one end of a worm gear 9 via a one-way bearing. The bearings allow the rotating shaft 7 to rotate only in the forward direction. A worm gear 10 is fixedly mounted on the rotating shaft 7. The worm 9 meshes with the worm gear 10. A gear transmission structure is provided between the movable tube 5 and the worm 9. The product of the transmission ratio of the gear transmission structure and the transmission ratio between the worm 9 and the worm gear 10 is 1. The gear transmission structure consists of a set of bevel gears, a set of gears, and a first shaft. The first shaft is rotatably mounted in the housing 1. The bevel gears are located between the first shaft and the movable tube 5. The bevel gears on the movable tube 5 are mounted through a one-way bearing. The gear set is located between the first shaft and the worm 9. A control device is provided in the control box 2. The motor 8 is electrically connected to the control device. A limit device is provided on the movable tube 5 to control the rotation angle of the movable tube 5. When motor 8 is turned on, its output shaft rotates forward, driving shaft 7 to rotate forward via worm 9 and worm wheel 10. Shaft 7 then rotates turntable 3, allowing for blank drawing. When motor 8 is turned off, the limiting function between worm 9 and worm wheel 10 locks shaft 7, preventing turntable 3 from rotating. Turning handwheel 6 forward drives movable tube 5, which in turn drives worm 9 via gear transmission, thus rotating turntable 3 by a certain angle, limiting its rotation. The device can limit the rotation angle of the movable tube 5. After rotation, the movable tube 5 can rotate in the opposite direction and reset under the action of the torsion spring. At this time, the worm gear 9 will not be driven to rotate through the gear transmission device. Compared with the existing pottery pulling device, when the motor 8 is not working, the turntable 3 can be locked to prevent the turntable 3 from rotating randomly. Secondly, the rotation angle of the movable tube 5 is limited by the limiting device, so that the turntable 3 can be driven to rotate at a certain angle by rotating the handwheel 6, which facilitates the processing of polygonal ceramic blanks and the rotation angle is more precise, thus facilitating the processing and manufacturing of polygonal ceramic blanks.

[0026] like Figure 2As shown, in a further preferred embodiment, the control device comprises a spring rod 11, a horizontal first rack 12, a roller 13, a first gear 14, a vertical movable rod 15, a horizontal second rack 16, a second gear 17, a push switch 18, a control knob 19, and a control board. The control board is an existing PLC controller. The top surface of the control box 2 has a through slot, and the roller 13 is disposed inside the control box 2, located at the through slot. The first gear 14 is coaxially mounted with the roller 13 and meshes with the first rack 12. A first limiting slide block structure is provided between the mounting shaft of the roller 13 and the control box 2. The lower end of the spring rod 11 is fixedly connected to the bottom surface of the control box 2, and a second limiting slide block structure is provided between the upper end of the spring rod 11 and the bottom of the first rack 14. The movable rod 15 is disposed on the first rack 16. On one side of rack 12, one end of the first rack 12 and one side of the movable rod 15 are provided with a third limiting slide groove slider structure. One end of the second rack 16 is fixedly connected to the movable rod 15. The second rack 16 meshes with the second gear 17. The second gear 17 is set on the rotation shaft of the control knob 19. The control knob 19 is fixedly installed in the control box 2. The second gear 17 is located above the second rack 16. The bottom surface of the second rack 16 contacts and slides with the bottom surface of the control box 2. This structure can limit the second rack 16, so that the second rack 16 cannot move up and down, and prevent the second rack 16 from separating from the second gear 17. The push switch 18 is fixedly installed on the bottom surface of the control box 2. The push switch 18 is located directly below the roller 13. The motor 8 is electrically connected to the control board. The push switch 18 and the control knob are both electrically connected to the control board. By placing your foot on the top surface of the control box 2 and pressing down on the roller 13 with your toes, the roller 13 can contact the push switch 18. The push switch 18 can control the start and stop of the motor 8 via the control board. When the motor 8 starts, the movement of the foot can drive the roller 13 to rotate. The rotation of the roller 13 can drive the first rack 12 to move, which in turn can drive the second rack 16 to move via the movable plate 15. The movement of the second rack 16 drives the control knob 19 to rotate via the second gear 17, which can then control the output shaft speed of the motor 8 via the control board. Compared with the existing controllers that control the switch by stepping on the foot, this control device controls the on / off state of the motor 8 and the output shaft speed separately by moving and rotating the roller 13, and both are completed by the foot. During use, there is no need to continuously step on the roller, making it more convenient to use. Furthermore, it prevents changes in the rotation speed of the turntable 2 due to changes in the force applied by the foot, thus avoiding affecting the processing of the ceramic blank.

[0027] like Figure 1As shown, in a further preferred embodiment, an anti-slip pad 20 is fixedly installed on the bottom surface of the outer wall of the control box 2. The anti-slip pad 20 can increase the friction between the control box 2 and the placement surface, and prevent the control box 2 from sliding when the roller 13 is rotated by sliding the foot, making it more convenient to use.

[0028] like Figure 2 As shown, in a further preferred embodiment, the control box 2 has a recessed structure at the through slot. This structure facilitates stepping down on the roller 13 and allows the roller 13 to rotate by moving the foot, making it more convenient to use.

[0029] like Figure 1 As shown, in a further preferred embodiment, the limiting device comprises a control groove 21 and a screw 22. The control groove 21 is formed on the outer periphery of the movable tube 5 and is arc-shaped. The depth of the control groove 21 decreases from one end to the other. One end of the screw 22 is located within the control groove 21 and passes through the housing 1 with a threaded connection. By rotating the screw 22, the screw 22 can move left and right, thereby adjusting the length of the screw 22 within the limiting groove 14, thus limiting the rotation of the movable tube 5 and controlling the limiting angle.

[0030] like Figure 1 As shown, in a further preferred embodiment, a handle 23 is fixedly mounted on the other end of the screw 22. The handle 23 provides a point of force, thereby facilitating the rotation of the screw 22 and making it convenient to use.

[0031] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
