Description

Technical Field

[0001] The invention relates to the field of ceramic wine bottle blank making production devices, in particular to a ceramic wine bottle centrifugal blank making device. Background Art

[0002] A wine bottle is a container for wine. Historically, wine bottles were mostly presented to the world in a simple style of "soy sauce bottle", glass, with little information and no heavy decoration. The materials of wine bottles are becoming more and more diversified, including gold-plated, copper-plated, iron, tin, stainless steel, pottery, purple sand, porcelain, wood, bamboo, glass, horn, bakelite, etc. Wine bottles of various materials show their own characteristics and styles. Some are gorgeous and precious, some are solemn and generous, and some are light. Common wine bottles include ceramic bottles, glass bottles, plastic bottles, etc., among which ceramic bottles are particularly popular.

[0003] However, in the traditional ceramic wine bottle blank making production line, the installation and disassembly of the mold clamp is inconvenient and cumbersome when in use. In addition, during the mold bottle making production process, if only a single grouting is performed into the mold, the thickness of the produced product may be uneven. In this case, the mold needs to be rotated during the mold grouting. However, when the motor and the mold rotate in coordination, more structures and steps are required, which results in a waste of time and an increase in cost. In addition, most of the existing blank making devices have the problems of large size, large space occupation and high production cost. Summary of the invention

[0004] The purpose of the present invention is to provide a centrifugal blank making device for ceramic wine bottles, which saves complicated processes and time, has a small size, a compact structure, uniform slurry injection, and bubble-free blank making, thereby improving efficiency and ensuring product quality.

[0005] The technical solution of the present invention is achieved in this way:

[0006] The ceramic wine bottle centrifugal blank making device described in the present invention comprises a bracket, a plurality of clamps installed on the bracket for clamping and fixing the wine bottle mold, and a centrifugal mechanism for driving the clamps to rotate so that the injected wine bottle mold can be rotated for centrifugal blank making. The centrifugal mechanism comprises a lifting mechanism installed on the bracket and a centrifugal rotating mechanism installed on the lifting mechanism. A plurality of clamping joints that can drive the clamps to rotate are installed on the centrifugal rotating mechanism. Two adjacent clamping joints rotate staggered under the drive of the centrifugal rotating mechanism. A clamping structure and a limiting structure that are engaged with the clamping joint are provided on the clamp. The limiting structure can be engaged and locked with the bracket so that the clamp will not rotate by itself when the clamp clamps the wine bottle mold for translation. The clamping joint is engaged with the clamp when rising with the lifting mechanism, and the limiting structure is released from the engagement and locking with the bracket so that the clamp and the wine bottle mold therein can be rotated for centrifugal blank making under the drive of the centrifugal rotating mechanism.

[0007] Further, the centrifugal rotating mechanism includes at least two centrifugal motors and a transmission assembly, a plurality of centrifugal rotating shafts (preferably at least four centrifugal rotating shafts), the top of each centrifugal rotating shaft is equipped with the clamping joint, two adjacent centrifugal rotating shafts are driven by different centrifugal motors to rotate staggered, and the two separated centrifugal rotating shafts are connected by a transmission belt assembly to achieve synchronous rotation. The staggered rotation angle of the two adjacent centrifugal rotating shafts can be determined according to the specific shape of the clamp, and the staggered angle can be less than 90 degrees, preferably 90 degrees.

[0008] In order to ensure that the centrifugal shaft returns to its original position when the centrifugal rotation action ends, a centrifugal origin induction block is installed on the centrifugal shaft, and a corresponding induction switch is provided on the lifting frame.

[0009] In order to make the centrifugal structure more reliable and run more smoothly, the lifting frame is provided with a connector rotatably connected to the centrifugal shaft, the centrifugal shaft is penetrated with a connecting ball connected to the spherical surface of the connector, and the connector is correspondingly provided with a cavity for the connecting ball to be accommodated and rotated inside. Generally, the connecting ball is penetrated in the middle or upper middle part of the centrifugal shaft.

[0010] Furthermore, the bracket includes a base frame, a movable positioning frame installed above the base frame, and a fixed plate fixed on the movable positioning frame that can cooperate with the limiting structure and be engaged with the fixed plate. The clamp is locked on the movable positioning frame by the cooperation and engagement of the limiting structure and the fixed plate. The movable positioning frame can translate the clamp holding the wine bottle mold under the action of the driving device.

[0011] Furthermore, the lifting mechanism includes a lifting frame, a lifting cylinder installed at both ends of the base frame, and a vertical guide slider arranged at both ends of the base frame. The lifting rod of the lifting cylinder is connected to the top plate of the lifting frame, and the two ends of the lifting frame are respectively provided with vertical slide grooves that cooperate with the guide slider. Furthermore, the lifting mechanism also includes a synchronous belt fixedly connected to the lifting frame and arranged at both ends of the base frame, an upper rotating wheel and a lower rotating wheel connected to the synchronous belt, and the two lower rotating wheels are connected through a connecting shaft arranged on the base frame. Preferably, two guide sliders located on both sides of the lifting frame are respectively provided at both ends of the base frame, so that there are a total of 4 groups of guide sliders and two groups of synchronous belts at both ends for flexible synchronization, so that the operation of the mechanism is more stable and smooth.

[0012] The clamping joint includes a coupling installed at the top of the centrifugal shaft, a plug connector installed at the upper end of the coupling, and a plug rod and a hoop that reliably connect the plug connector and the coupling together. The plug connector and the coupling are provided with corresponding through holes for the plug rod to pass through, and the through hole on the plug connector is a long horizontal hole. A clamping strip is provided at the top of the plug connector, and the clamping strip can be used to push the limit structure and realize the matching clamping with the clamping structure on the clamp. The advantages of the coupling and the plug connector being assembled and the through hole on the plug connector being set as a long horizontal hole are: a movable adjustment width is provided for the plug connector, so that even if the position of the plug connector and the clamping structure below the clamp is not very accurate, the plug connector can be connected to the clamping structure above by adjusting the position of the plug connector, without the need to disassemble the clamp or the plug connector again, and the installation is extremely convenient.

[0013] The clamp comprises a clamping frame with a bottom placing plate and two side clamping plates, the clamping structure comprises a clamping column installed at the bottom of the placing plate, the limiting structure comprises a transverse clamping pin and a clamping pin return spring which can be installed at the lower end of the clamping column and have clamps at both ends, the upper end of the clamping pin return spring is connected to the clamping column and the lower end is connected to the transverse clamping pin, the bottom of the clamping column is correspondingly provided with a clamping groove for the transverse clamping pin to move up and down, and the fixing plate is correspondingly provided with a through hole for accommodating the lower end of the clamping column and a clamping hole for positioning with the transverse clamping pin. When the clamping joint rises with the lifting mechanism, the transverse clamping pin is pushed up, so that the clamping pin return spring above the transverse clamping pin is compressed, the transverse clamping pin moves upward, and escapes from the clamping hole restriction on the fixing plate. At the same time, the clamping joint and the clamping column are reliably clamped and the wine bottle mold in the clamp can be rotated under the action of the centrifugal rotating mechanism for centrifugal blanking.

[0014] Furthermore, the movable positioning frame is provided with a positioning plate for the clamping column to pass through, and a bearing and a positioning ring installed on the positioning plate. The clamping column is rotatably connected to the positioning plate through the bearing, and the fixed plate is located below the positioning plate.

[0015] The advantages of the present invention compared with the prior art are:

[0016] First, the present invention is easy to operate, saves complicated procedures, and can also save time. In addition, the staggered rotation of the clamps driven by the clamping joints in the centrifugal mechanism can effectively reduce the distance between the clamps, thereby reducing the size of the equipment and reducing production costs.

[0017] 2. The lifting mechanism in the centrifugal mechanism has been optimized. In addition to the lifting cylinders at both ends of the bracket, there are also slider guides and a set of synchronous belts to achieve flexible synchronization, making the mechanism run more stable and smoother.

[0018] 3. A movable adjustment width is provided for the plug connector on the card connector. In this way, even if the position of the plug connector and the card connection structure below the clamp is not very accurate, the position of the plug connector can be adjusted to ensure that the plug connector is connected to the card connection structure above. There is no need to disassemble the clamp or the plug connector for alignment and installation, which is extremely convenient to install.

[0019] Fourth, the centrifugal blank making method of the present invention can eliminate the bubbles in the grouting to the greatest extent, and the slurry components injected into the cavity of the wine bottle mold can be evenly injected without causing the product to have different thicknesses.

[0020] The present invention will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-Figure 6As shown, the ceramic wine bottle centrifugal blank making device of the present invention comprises a bracket 1, a plurality of clamps 2 installed on the bracket 1 for clamping and fixing the wine bottle mold, and a centrifugal mechanism for driving the clamps 2 to rotate so that the injected wine bottle mold is rotated for centrifugal blank making, the centrifugal mechanism comprises a lifting mechanism 3 installed on the bracket 1, and a centrifugal rotating mechanism 4 installed on the lifting mechanism 3, a plurality of clamping joints 5 that can drive the clamps 2 to rotate are installed on the centrifugal rotating mechanism 4, and two adjacent clamping joints 5 are staggered and rotated under the drive of the centrifugal rotating mechanism 4, and a clamping structure and a limiting structure 6 that are clamped with the clamping joints 5 are provided on the clamp 2, and the limiting structure can be clamped and locked with the bracket 1, so that the clamp will not rotate automatically when the clamp 2 clamps the wine bottle mold for translation, and it also prevents the clamp from rotating under normal conditions and affecting the installation of the wine bottle mold. The clamping joint 5 can be clamped with the clamp 2 when the lifting mechanism 3 rises, and the limiting structure 6 can release the clamping lock of the bracket 1 on the clamp 2, so that the clamp 2 and the wine bottle mold therein can be rotated and centrifuged under the drive of the centrifugal rotating mechanism 4. Among them, the bracket 1 includes a supporting base frame 11, a mobile positioning frame 12 installed on the base frame 11, and a fixed plate 13 fixed on the mobile positioning frame 12 and capable of being clamped with the limiting structure 6. The clamp 2 is locked on the mobile positioning frame 12 through the clamping of the limiting structure and the fixed plate 13. The mobile positioning frame 12 can make the clamp 2 holding the wine bottle mold translate under the action of the driving device. The mobile positioning frame 12 is provided with a positioning plate 14 for the clamping column 23 to pass through, a bearing 15 and a positioning ring installed on the positioning plate 14, the clamping column 23 is rotatably connected with the positioning plate 14 through the bearing 15, and the fixed plate 13 is located below the positioning plate 14. The centrifugal rotating mechanism 4 includes at least two centrifugal motors 41 and a transmission assembly 42, at least four centrifugal shafts 43, the top of each centrifugal shaft 43 is equipped with the clamping joint 5, two adjacent centrifugal shafts 43 are driven by different centrifugal motors 41 to rotate 90 degrees, and the two separated centrifugal shafts 43 are connected by a transmission belt assembly 44 to achieve synchronous rotation. That is to say, the two separated centrifugal shafts 43 are respectively an active centrifugal shaft and a driven centrifugal shaft, and the transmission assembly 42 includes a driving transmission group connecting a centrifugal motor and an active centrifugal shaft, and the driving transmission group includes a driving gear connected to the centrifugal motor 41, a driving gear installed at the lower end of an active centrifugal shaft, and a driving belt connecting the driving gear and the driving gear. The transmission belt assembly includes a second driving gear installed at the lower end of the active centrifugal shaft, a driven gear installed on the driven centrifugal shaft, and a synchronous belt 2 connecting the second driving gear and the driven gear. The centrifugal motor drives the driving gear and the driving centrifugal shaft to rotate through the driving belt, and also drives the driven gear and the driven centrifugal shaft to rotate through the synchronous belt 2 connected to the driving gear 2, so that the separated driving centrifugal shaft and the driven centrifugal shaft can rotate synchronously.For example, first, one of the centrifugal motors rotates first, driving the two centrifugal shafts and the clamps thereon to rotate and the fixtures to rotate, so that a set of fixtures (such as two fixtures) rotate 90 degrees first. Then, the other centrifugal motor also starts to rotate. In this way, the two centrifugal motors drive the four fixtures to rotate 90 degrees. The purpose of this staggered rotation is: if they rotate at the same time, in order to prevent collision between the fixtures, a larger fixture spacing is required, which will widen the width of the entire machine. Therefore, this staggered rotation method can reduce the distance between the fixtures and reduce the size of the equipment.

[0027] In order to ensure that the centrifugal shaft returns to the original position when the centrifugal rotation action ends, a centrifugal origin sensing block 45 is installed on the centrifugal shaft 43, and a corresponding sensing switch 46 is provided on the lifting mechanism 3. In this way, when the rotation time of the centrifugal rotation blank making process is reached, as long as the sensing switch senses the centrifugal origin sensing block 45 on the centrifugal shaft, the centrifugal motor stops the centrifugal shaft from rotating, and the centrifugal shaft stays at the original position, ready for the next rotation.

[0028] In order to make the centrifugal shaft drive the fixture to rotate more smoothly, the lifting mechanism 3 is provided with a connector 47 that is rotatably connected to the centrifugal shaft 43, and the centrifugal shaft 43 is penetrated with a connecting ball 48 that is spherically connected to the connector 47. The connector 47 is correspondingly provided with a cavity for the connecting ball 48 to be accommodated and rotated therein. In order to make the lifting mechanism lift more stably and smoothly, the lifting mechanism 3 includes a lifting frame 32, a lifting cylinder 31 installed at both ends of the base frame 11, a vertical guide slider 33 arranged at both ends of the base frame 11, a synchronous belt 34 fixedly connected to the lifting frame 32, and an upper rotating wheel and a lower rotating wheel connected to the synchronous belt 34. The lifting rod of the lifting cylinder 31 is connected to the top plate of the lifting frame 32, and the two ends of the lifting frame 32 are correspondingly provided with vertical sliding grooves that cooperate with the guide slider 33. The two lower rotating wheels located at both ends of the base frame 11 are connected by a connecting shaft 35 arranged on the base frame, so that the synchronous belts at both ends of the base frame can achieve synchronous and flexible lifting. In order to further make the centrifugal shaft drive the fixture to rotate more smoothly and install more conveniently, the clamping joint 5 includes a coupling 51 installed at the top of the centrifugal shaft 43, a plug connector 52 installed at the upper end of the coupling 51, and a plug rod 53 and a hoop 54 (generally a rubber ring) that reliably connect the plug connector 52 and the coupling 51. The plug connector and the coupling are provided with corresponding through holes for the plug rod to pass through, and the through holes on the plug connector are long strip-shaped transverse holes 522. Since the through holes on the plug connector are long strip-shaped transverse holes 522, a space is provided for the plug connector to be able to move horizontally on the coupling to adjust the position, and the rubber ring can be used to limit the position after the position is adjusted. A clamping strip 521 is provided at the top of the plug connector 52, and the clamping strip 521 can push up the limiting structure 6 and realize the matching clamping connection with the clamping structure on the fixture 2. The clamp 2 includes a clamping frame with a bottom placement plate 21 and two side clamps 22. The clamping structure includes a clamping column 23 installed at the bottom of the placement plate 21. The limiting structure 6 includes a transverse clamping pin 61 and a clamping pin reset spring 62 installed at the lower end of the clamping column 23 so as to be able to move up and down. The upper end of the clamping pin reset spring 62 is connected to the clamping column 23 and the lower end is connected to the transverse clamping pin 61. The bottom of the clamping column 23 is correspondingly provided with a clamping groove 24 for the transverse clamping pin 61 to move up and down. The fixing plate 13 is provided with a through hole for receiving the lower end of the clamping column 23 and a clamping hole for clamping and positioning with the transverse clamping pin 61. When the clamping joint 5 rises with the lifting mechanism, the clamping pin reset spring 62 above the transverse clamping pin 61 is compressed, and the transverse clamping pin 61 moves upward and escapes from the clamping hole on the fixing plate 13, while the clamping joint 5 and the clamping column 23 are reliably clamped and the wine bottle mold in the fixture 2 can be rotated and centrifugally formed under the action of the centrifugal rotating mechanism. Two clamps are arranged on the transverse clamping pin 61 to play a positioning role and prevent the transverse clamping pin from moving left and right.The placement plate can be used to place the wine bottle mold on it, and the wine bottle mold can move with the translational movement of the placement plate, so that the wine bottle mold after grouting can be removed in time, thereby facilitating continuous processing and increasing processing efficiency. Further, at least one clamping plate of the clamp is equipped with a pair of clamping wheels connected together by a rotating shaft, and the clamping wheel cooperates with another clamping plate to clamp the wine bottle mold.

[0029] The working principle of the present invention is further described in detail below with reference to the accompanying drawings:

[0030] The frame is equipped with a paddle injection device, a ceramic wine bottle centrifugal blank making device, and an electric control box. At the beginning, the transverse bayonet under the fixture is clamped on the fixed plate on the mobile positioning frame 12, so that the fixture is fixed on the bracket. Four fixtures clamp four wine bottle molds, and arrive at the grouting station with the mobile positioning frame under the chain transmission, and the grouting device on the upper part of the frame performs grouting. After the grouting is completed, the centrifugal mechanism under the fixture starts to work. The lifting rods of the lifting cylinders at both ends extend upward to push the lifting frame and the centrifugal shaft up, and the clamping strip on the clamping joint 5 at the upper end of the centrifugal shaft is inserted into the bottom of the clamping column under the fixture 2, and the transverse bayonet 61 is pushed up when the centrifugal shaft rises, so that the bayonet reset spring 62 above the transverse bayonet 61 is compressed, and the transverse bayonet 61 moves upward, escapes from the clamping hole restriction on the fixed plate 13, and at the same time, the clamping joint 5 is reliably connected with the clamping column 23. After the transverse bayonet 61 is freed from the restriction of the fixed plate, the fixture can be rotated. At this time, the lifting cylinder stops lifting the lifting frame, and one of the centrifugal motors starts first, driving the interval of a group of centrifugal shafts and fixtures to rotate, so that the interval of a group of fixtures (such as two fixtures) rotates 90° first. Then, the other centrifugal motor also starts to rotate and drives the other group of fixtures to rotate. In this way, the two centrifugal motors drive the four fixtures to perform a rotational motion staggered by 90 degrees, so that the wine bottle mold located in the fixture 2 can rotate centrifugally to make blanks under the action of the centrifugal rotating mechanism. When the centrifugal rotating action ends, in order to facilitate induction detection to ensure that the centrifugal shaft returns to the original position, a centrifugal origin induction block is installed on at least two centrifugal shafts, and an induction switch is installed at a suitable position away from the centrifugal origin induction block. When the lifting rod of the lifting cylinder retracts, the lifting frame and the centrifugal shaft are driven to descend, so that the clamping joint at the upper end of the centrifugal shaft is separated from the horizontal bayonet of the fixture, and the horizontal bayonet is reset back to the clamping hole of the fixed plate under the elastic force of the bayonet reset spring. The centrifugal blanking process ends.
