Description

Technical Field

[0001] The invention relates to the technical field of clay forming devices, and in particular to a clay forming device for ceramic production and a forming process thereof. Background Art

[0002] In the traditional ceramic production process, clay molding is a crucial step, which is directly related to the dimensional accuracy, surface quality and production efficiency of the product. With the development of technology, specialized clay molding equipment for ceramic production has gradually been introduced into the ceramic production process to improve production efficiency and product quality.

[0003] The cutting angle of the cutter used for cutting and scraping the flash waste overflowed from the top opening of the molding die in the existing clay molding device is mostly fixed, resulting in a fixed direction of discharge of the cut and scraped flash waste, which will accumulate in a fixed position in the container used to intercept the waste, causing the waste to accumulate rapidly in the fixed position space and expand rapidly, which may quickly occupy the molding die and the rotating working space of the rotating seat for placing and driving the molding die, requiring relatively high frequency cleaning of the waste, and the operation is relatively troublesome and inconvenient;

[0004] In addition, although some tools are configured to have a rotatable and adjustable cutting angle, which can change the direction in which the flash waste is thrown out and discharged, and can relatively evenly distribute the scraped flash waste in the internal space of the waste interception container, thereby preventing the flash waste from quickly gathering and expanding in volume and reducing the frequency of cleaning the flash waste, the angle adjustment operation of the tool still requires additional manual effort and is frequently implemented, and the operation is still relatively cumbersome and inconvenient. Summary of the invention

[0005] In view of this, the present invention provides a clay forming device and a forming process for ceramic production to solve the problem that although some knives are configured to have a rotatable cutting angle, the angle adjustment operation still requires additional manual effort and is frequently implemented, and the operation is still cumbersome and inconvenient.

[0009] Furthermore, a cross brace mounting plate is welded on the left side wall of the fence box, a mounting sleeve is welded on the head end of the cross brace mounting plate, and two limit rings are welded and sleeved on the mounting sleeve at upper and lower intervals.

[0010] Furthermore, a rotating ring is welded at the tail end of the horizontal part of the L-shaped mounting rod, and the rotating ring is rotationally matched with the mounting sleeve and is limited between two limiting rings;

[0011] A U-shaped frame is welded to the top of the vertical slide plate, and the tail end of the trimming blade is plug-fitted with the frame and is threadedly fastened in the frame;

[0012] The outer circumference of the rotating circle is welded with a protruding supporting force transmission ear block.

[0013] Furthermore, the centrifugal drive mechanism is composed of an I-shaped counterweight block, a first connecting rod and a shaft sleeve connected together, wherein the shaft sleeve is slidably mounted on the middle part of the driving shaft;

[0014] The portion of the driving shaft below the sleeve is symmetrically welded with two horizontal positioning shafts, on which two I-shaped counterweights are symmetrically and slidingly installed through spring pushing, and two first connecting rods are symmetrically and rotatably connected between the two I-shaped counterweights and the sleeve.

[0015] Furthermore, two retaining rings are welded on the shaft sleeve at intervals, and two force transmission rings are rotatably installed side by side on the shaft sleeve. The two force transmission rings are limited between the two retaining rings, and a second connecting rod is rotatably connected between the lower force transmission ring and the bottom end of the vertical slide plate.

[0016] Furthermore, two Z-shaped vertical support rods are welded symmetrically at the top of the front part of the bottom wall of the fence box, and a reciprocating screw is rotatably installed between the tops of the two Z-shaped vertical support rods. A driven gear is mounted on the protruding part of the left end of the reciprocating screw, and the driven gear is connected to the reciprocating screw through an internal ratchet mechanism.

[0017] A sliding sleeve matched with the reciprocating driving groove is slidably mounted on the reciprocating screw, and a fourth connecting rod is rotatably connected between the sliding sleeve and the force transmission ear block.

[0018] Furthermore, a terrestrial shaped positioning block is welded to the top of the Z-shaped vertical support rod on the left side, and a rack that slides straightly forward and backward is installed on the terrestrial shaped positioning block, and the rack is meshed with a driven gear for transmission;

[0019] A third connecting rod is rotatably connected between the rear end of the rack and the upper force transmission ring.

[0020] Furthermore, a brake motor is threadedly mounted at the center of the bottom of the fence box, and the brake motor is connected to the driving shaft for transmission. When loading and unloading the molding die, the brake motor is in a braked and stationary state.

[0021] Furthermore, an inner groove is provided at the top of the rotating seat, and the forming mold is plugged into and matched with the inner groove;

[0022] A T-shaped mounting frame is fixedly installed at an adjacent position on the rear side of the fence box, a swing rolling mechanism is rotatably installed on the top end of the T-shaped mounting frame, and a rolling ball head that can be driven by high-speed rotation is arranged at the head end of the swing rolling mechanism.

[0023] Furthermore,

[0024] Two discharge troughs are symmetrically provided at the rear positions of the left and right side walls of the fence box, and a cover plate is inserted and sealed in each of the two discharge troughs by a threaded fastening plug.

[0025] A molding process of a clay molding device for ceramic production, comprising the following operating steps:

[0026] ① Place the clay raw material (cake or block) in the forming mold, then insert the forming mold into the inner groove at the top of the forming mold, and start the brake motor to drive the rotating seat to rotate at high speed;

[0027] ② Then manually press down the swing rolling mechanism to insert the high-speed rotating rolling ball head into the forming mold and roll it into contact with the clay raw material. The rolling ball head can roll and crush the clay raw material evenly on the inner wall of the forming mold for forming;

[0028] ③ When the rotating seat rotates, the trimming blade is driven by the rotating centrifugal force to slide inward and fit into contact with the outer edge of the top opening of the forming mold, so as to peel off and remove the clay flash overflowed from the top opening of the forming mold;

[0029] ④ When the rotating seat rotates, the centrifugal force can also drive the trimming blade to swing back and forth along the driving shaft, changing the direction of the stripped flash waste to be thrown away and unloaded, and evenly scattering the flash waste in the space in the back half of the fence box;

[0030] ⑤. Finally, after the clay is formed, the swing rolling mechanism is swung upward and reset to separate the rolling ball head from the forming mold, and the forming mold together with the clay product formed inside it is removed from the rotating seat.

[0031] The present invention provides a clay forming device for ceramic production and a forming process thereof, which has the following beneficial effects:

[0032] During use of the present invention, the trimming blade can swing back and forth around the driving shaft, changing its relative cutting angle with the flash waste and the direction of the flash waste being thrown away and unloaded after being cut off, so that the flash waste after being cut off can swing back and forth with the trimming blade, and be relatively evenly dispersed and intercepted in the space in the rear half of the fence box, making full use of the interception and containing space of the fence box. Compared with the prior art, it avoids the flash waste after being cut off from being thrown away and unloaded in a fixed direction, accumulating in a fixed position in the space in the rear half of the fence box, and rapidly gathering and expanding in volume, and rapidly encroaching on the rotating operating space of the rotating seat, so that the fence box can indirectly intercept and contain more flash waste, which helps to extend the time interval for cleaning and unloading the flash waste. The operation is relatively convenient, saving time and effort.

[0033] In addition, when the sleeve slides up and down, it can drive the two force transmission rings to rise and fall synchronously, which makes it possible for the inward and outward insertion and sliding operations of the trimming blade and the swing adjustment operation of the cutting angle to be indirectly driven by the rotating centrifugal force of the driving shaft. Compared with the existing technology, it saves the trouble of additional manual effort to frequently perform inward and outward sliding, telescopic and swing adjustment of the trimming blade, helps to further improve the convenience of operation and use of the device, and also saves the need to configure additional drive motors for telescopic and swing adjustment of the trimming blade.

[0034] In addition, the internal ratchet mechanism can ensure that the rack and the driven gear can drive the reciprocating screw in a single direction, that is, only when the rack slides forward and engages to drive the driven gear to rotate counterclockwise, the driven gear is coupled with the reciprocating screw power to torsion drive the reciprocating screw, avoiding the situation where the driven gear is also coupled with the reciprocating screw power when the rack slides backward and engages to drive the driven gear to rotate, and torsion drives the reciprocating screw to rotate, causing the reciprocating screw to be driven by a small number of reciprocating rotations in both directions, and cannot be driven to rotate continuously in one direction, and cannot be driven to drive the sleeve to slide left and right along its full stroke, thereby reducing the swinging motion amplitude of the trimming blade and the flash waste during unloading, affecting the uniform distribution and unloading of the flash waste inside the fence box.

[0035] In addition, the rear half of the space in the fence box is used to hold the flash waste scraped off by cutting, and all the mechanisms that drive the trimming blades to telescope, slide and swing inward and outward are arranged in the front half of the space in the fence box. This can separate the driving mechanism and the flash waste, reduce the chance of the flash waste sticking to and blocking the driving mechanism, and help ensure the normal and long-term operation of the driving mechanism inside the fence box.

[0059] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0060] For convenience of description, the length direction of the cross brace mounting plate 101 is marked as the left-right direction, and the width direction is marked as the front-back direction.

[0061] Please refer to Figures 1 to 9 ;

[0062] Embodiment 1:

[0063] The present invention proposes a clay forming device for ceramic production, comprising: a fence box 1, a horizontal support mounting plate 101, a mounting sleeve 1011, a Z-shaped vertical support rod 102, a reciprocating screw 1021, a driven gear 1022, a sliding sleeve 1023, a soil-shaped positioning block 1024, a rack 103, a cover plate 104, a swing rolling mechanism 2, a rolling ball head 201, a T-shaped mounting frame 3, a rotating seat 4, a forming mold 5, a trimming blade 6, a brake motor 7, a driving shaft 8, and a horizontal positioning shaft. 801, I-shaped counterweight block 802, first connecting rod 8021, force transmission ring 803, second connecting rod 8031, third connecting rod 8032, shaft sleeve 804, L-shaped mounting rod 9, horizontal track shaft 901, vertical slide plate 902, rotating circle 903, force transmission ear block 9031, fourth connecting rod 904, the center position of the bottom wall of the fence box 1 is penetrated and rotatably installed with a driving shaft 8, the top end of the driving shaft 8 is threadedly fastened with a rotating seat 4, and the rotating seat 4 is used for inserting and placing the molding mold 5;

[0064] Among them, an L-shaped mounting rod 9 is rotatably mounted on the top part of the driving shaft 8, and two horizontal track shafts 901 are welded at an interval up and down on the vertical part of the L-shaped mounting rod 9, and vertical slide plates 902 are slidably mounted on the two horizontal track shafts 901. The top parts of the two horizontal track shafts 901 are threadedly fastened with trimming blades 6, and when the trimming blades 6 slide inward, they are in contact with the outer edge of the top opening of the forming mold 5, and are used to strip and remove the flash overflowed by rolling on the top opening of the forming mold 5; the trimming blades 6 can swing back and forth along the driving shaft 8 to adjust the direction of the flash after stripping and removal; the part of the driving shaft 8 located below the L-shaped mounting rod 9 is provided with a centrifugal driving mechanism that uses the rotating centrifugal force to drive the trimming blades 6 to swing back and forth and slide inward and outward;

[0065] Specifically, the flash waste after cutting is thrown away along the tangent direction of the trimming blade 6 and the top opening of the forming mold 5 and intercepted and unloaded in the space in the rear half of the fence box 1. The trimming blade 6 can reciprocate around the driving shaft 8 to change its relative cutting angle with the flash waste and the direction of the flash waste after cutting. The flash waste after cutting can be reciprocated with the trimming blade 6, and relatively evenly distributed and intercepted in the space in the rear half of the fence box 1, making full use of the interception and containing space of the fence box 1. Compared with the prior art, it avoids the fixed direction of the flash waste after cutting and accumulating in a fixed position in the space in the rear half of the fence box 1, rapidly accumulating and expanding in volume, and quickly occupying the rotating working space of the rotating seat 4, so that the fence box 1 can indirectly intercept and contain more flash waste, which helps to extend the time interval for cleaning and unloading the flash waste. It is more convenient to operate and use, saving time and effort.

[0066] It is worth noting that the swinging motion amplitude of the trimming blade 6 should be controlled at about 90 degrees;

[0067] The rear half of the space in the fence box 1 is used to hold the flash waste scraped off by cutting, and all the mechanisms that drive the trimming blade 6 to perform inward and outward telescopic sliding and swing adjustment are arranged in the front half of the space in the fence box 1. This can separate the driving mechanism and the flash waste, reduce the probability of the flash waste sticking to and blocking the driving mechanism, and help ensure the normal and long-term operation of the driving mechanism inside the fence box 1.

[0068] Preferably, a cross brace mounting plate 101 is welded on the left side wall of the fence box 1, a mounting sleeve 1011 is welded on the head end of the cross brace mounting plate 101, and two limit rings are welded and sleeved on the mounting sleeve 1011 at upper and lower intervals.

[0069] Preferably, a rotating circle 903 is welded to the tail end of the horizontal part of the L-shaped mounting rod 9, and the rotating circle 903 is rotatably matched with the mounting sleeve 1011 and limited between two limiting rings; a U-shaped card frame is welded to the top of the vertical slide plate 902, and the tail end part of the trimming blade 6 is plug-fitted with the card frame and is threadedly fastened in the card frame; the circumferential outer ring of the rotating circle 903 is welded with a protruding supporting force transmission ear block 9031.

[0070] Preferably, the centrifugal drive mechanism is composed of an I-shaped counterweight 802, a first connecting rod 8021 and a sleeve 804, wherein the sleeve 804 is slidably mounted on the middle part of the driving shaft 8; two horizontal positioning shafts 801 are symmetrically welded on the portion of the driving shaft 8 below the sleeve 804, and two I-shaped counterweights 802 are symmetrically slidably installed on the two horizontal positioning shafts 801 through spring pushing, and two first connecting rods 8021 are symmetrically rotatably connected between the two I-shaped counterweights 802 and the sleeve 804;

[0071] The two first connecting rods 8021, the two I-shaped counterweights 802 and the shaft sleeve 804 are connected together to form two crank slider mechanisms. Through these two mechanisms, the two I-shaped counterweights 802 can slide away from each other, and can push and drive the shaft sleeve 804 to slide downward. When the two I-shaped counterweights 802 follow the high-speed rotation of the driving shaft 8, they can be driven by centrifugal force to slide away from each other outward. When the driving shaft 8 stops rotating, the two I-shaped counterweights 802 lose the centrifugal force to push outward and can be automatically rebounded by the springs on the two horizontal positioning shafts 801 to push and slide inward to reset. The shaft sleeve 804 is controlled to slide up and back to its original position, and when the shaft sleeve 804 slides up and down, the two force transmission rings 803 can be driven to rise and fall synchronously, so that the inward and outward insertion and sliding operation of the trimming blade 6 and the swing adjustment operation of the cutting angle can be indirectly driven by the rotating centrifugal force of the driving shaft 8. Compared with the prior art, the trouble of frequent inward and outward sliding, telescopic and swing adjustment of the trimming blade 6 is eliminated by additional manual effort, which helps to further improve the convenience of operation and use of the device, and can also eliminate the need to configure additional drive motors for telescopic and swing adjustment for the trimming blade 6.

[0072] Preferably, two retaining rings are welded and sleeved on the shaft sleeve 804 at intervals, and two force transmission rings 803 are rotatably mounted on the shaft sleeve 804 in parallel, and the two force transmission rings 803 are limited between the two retaining rings, and a second connecting rod 8031 ​​is rotatably connected between the lower force transmission ring 803 and the bottom end of the vertical slide plate 902;

[0073] The lower force transmission ring 803, the second connecting rod 8031 ​​and the vertical slide plate 902 are connected together to form a crank slider mechanism, through which the lower force transmission ring 803 can slide up and down to push and drive the vertical slide plate 902 and the trimming blade 6 to slide inward and outward to be plugged into and separated from the top opening of the forming mold 5. When the trimming blade 6 is separated from the top opening of the forming mold 5, the space at the top of the forming mold 5 can be vacated for the disassembly and assembly of the forming mold 5.

[0074] Preferably, two Z-shaped vertical support rods 102 are welded symmetrically at the top of the front side of the bottom wall of the fence box 1, and a reciprocating screw 1021 is rotatably installed between the tops of the two Z-shaped vertical support rods 102. A driven gear 1022 is mounted on the protruding part of the left end of the reciprocating screw 1021, and the driven gear 1022 is transmission-connected to the reciprocating screw 1021 through an internal ratchet mechanism; a sliding sleeve 1023 matching the reciprocating drive groove is slidably installed on the reciprocating screw 1021, and a fourth connecting rod 904 is rotationally connected between the sliding sleeve 1023 and the force transmission ear block 9031;

[0075] The sliding sleeve 1023, the force transmission ear block 9031, the rotating circle 903 and the fourth connecting rod 904 are connected together to form a crank slider mechanism. The left and right sliding sliding sleeve 1023 can drive the rotating circle 903 and the L-shaped mounting rod 9 to swing left and right along the mounting sleeve 1011 and the driving shaft 8 to adjust the cutting angle of the trimming blade 6, and the reciprocating screw 1021 can rotate to drive the sliding sleeve 1023 to slide left and right.

[0076] Preferably, a spherical positioning block 1024 is welded to the top of the left Z-shaped vertical support rod 102, a rack 103 that slides straightly forward and backward is installed on the spherical positioning block 1024, and the rack 103 is meshed with the driven gear 1022 for transmission; a third connecting rod 8032 is rotatably connected between the rear end of the rack 103 and the upper force transmission ring 803;

[0077] The rack 103, the third connecting rod 8032 and the upper force transmission ring 803 are connected together to form a crank slider mechanism, through which the upper force transmission ring 803 that slides up and down can push and drive the rack 103 to slide forward and backward, and when the rack 103 slides forward, it can mesh and drive the driven gear 1022 and the reciprocating screw 1021 to rotate, providing a driving force for the swing adjustment of the trimming blade 6; the internal ratchet mechanism can ensure that the rack 103 and the driven gear 1022 drive the reciprocating screw 1021 in a single direction, that is, only when the rack 103 slides forward and meshes to drive the driven gear 1022 to rotate counterclockwise, the driven gear 1022 and the reciprocating screw 1021 can rotate in a single direction. The screw 1021 is power coupled and torsional driven is applied to the reciprocating screw 1021 to avoid that when the rack 103 slides backward and engages to drive the driven gear 1022 to rotate, the driven gear 1022 is also power coupled with the reciprocating screw 1021, and torsional drives the reciprocating screw 1021 to rotate, causing the reciprocating screw 1021 to be driven by a small number of reciprocating rotations in both directions, and cannot be continuously driven to rotate in one direction, and cannot drive the sleeve 1023 to slide left and right along its full stroke, thereby reducing the swinging motion amplitude of the trimming blade 6 and the flash waste during unloading, affecting the uniform distribution and unloading of the flash waste inside the fence box 1.

[0078] Preferably, a brake motor 7 is threadedly mounted at the center of the bottom of the fence box 1, and the brake motor 7 is axially connected to the driving shaft 8 for transmission. When loading and unloading the molding mold 5, the brake motor 7 is in a braked and stationary state, and in use, the brake motor 7 is used to drive the driving shaft 8 and the rotating seat 4 to rotate at high speed.

[0079] Preferably, an inner groove is provided at the top of the rotating seat 4, and the molding die 5 is plugged into the inner groove; a T-shaped mounting frame 3 is fixedly installed at an adjacent position on the rear side of the fence box 1, and a swing rolling mechanism 2 is rotatably installed at the top of the T-shaped mounting frame 3, and a rolling ball head 201 that can be driven by high-speed rotation is provided at the head end of the swing rolling mechanism 2;

[0080] The swing rolling mechanism 2 is a mature prior art, and its specific structure, function and use method are well known to those skilled in the art, so it will not be described in detail here.

[0081] On the basis of the first embodiment, the second embodiment, as Fig.10 As shown:

[0082] A clay forming device for ceramic production also includes: two unloading troughs are symmetrically opened at the rear sides of the left and right side walls of the fence box 1, and a cover plate 104 is inserted and sealed in the two unloading troughs by threaded fastening plugs. The two cover plates 104 can be opened to facilitate the unloading of the flash waste intercepted and contained in the rear half of the fence box 1.

[0083] Working principle: When in use, first, place the clay raw material cake or block in the forming mold 5, then insert the forming mold 5 into the inner groove at the top of the forming mold 5, and then start the brake motor 7 to drive the rotating seat 4 to rotate at high speed;

[0084] Then, the rolling mechanism 2 is manually pressed down to make the high-speed rotating rolling ball head 201 inserted into the forming mold 5 and in rolling contact with the clay raw material. The rolling ball head 201 can roll and crush the clay raw material and evenly distribute it on the inner wall of the forming mold 5 for forming.

[0085] When the rotating seat 4 rotates, the centrifugal force drives the trimming blade 6 to slide inward and fit in with the outer edge of the top opening of the forming mold 5, so as to remove the clay flash overflowed from the top opening of the forming mold 5, and the centrifugal force can also drive the trimming blade 6 to swing back and forth along the driving shaft 8 when the rotating seat 4 rotates, so as to change the direction of the stripped flash waste material to be thrown away and discharged, and evenly disperse the flash waste material in the space of the rear half of the fence box 1;

[0086] Finally, after the clay is formed, the swing rolling mechanism 2 is swung upward and reset to separate the rolling ball head 201 from the forming mold 5, and the forming mold 5 together with the clay product formed inside is removed from the rotating seat 4.
