Description

Technical Field

[0001] This invention relates to drying technology, and more particularly to a drying apparatus for ceramic embryos. Background Technology

[0002] Ceramic pieces are often used as containers or decorative items in daily life. The production process of ceramic pieces requires processing by a variety of equipment, one of which is the drying equipment for ceramic blanks.

[0003] Currently, existing ceramic blank drying equipment involves workers directly placing the ceramic blanks onto supports within the drying equipment. This requires workers to be fully or partially inside the equipment, which may also be hot, posing safety hazards. Furthermore, workers must place certain types of ceramic blanks into the drying equipment within a specified timeframe for drying, and prolonged drying time can affect the quality of the ceramic blanks. This method not only takes a long time, but also requires the supports to be reconfigured according to the different sizes of the ceramic blanks, necessitating multiple support structures and reducing placement efficiency, thus extending the drying time. Summary of the Invention

[0011] The drying support is provided with symmetrically arranged pillars, support plates and support components. The support plates are set on the pillars through the support components. When the symmetrically arranged support plates are pulled in opposite directions, the support components are kept unfolded, and the distance between the symmetrically arranged support plates is changed.

[0012] In this invention, the rotating member is composed of a hinge part and a pushing part. The pushing part is inclined and has a pushing inclined surface that cooperates with the pushing member. The hinge part has a first hinge hole in the middle and the first hinge rod is disposed in the first hinge hole.

[0013] In this invention, the first hinge hole is provided with an insertion groove, and the first reset member is composed of a positioning section that cooperates with the insertion groove and a spiral section and an insertion section that are symmetrically arranged.

[0014] In this invention, the middle of the retaining member forms a second hinge hole that mates with the second hinge rod. The second hinge hole is provided with an insertion groove. The second resetting member consists of a positioning section that mates with the insertion groove and a symmetrically arranged spiral section and insertion section.

[0015] In this invention, the opening groove is provided with a concave arc surface, and a blocking protrusion is provided on the concave arc surface.

[0016] In this invention, the retaining member consists of a hinge end and a retaining end. The hinge end mates with an inwardly concave arc surface, and the hinge end is provided with a retaining protrusion that mates with a blocking protrusion. The retaining end mates with a tooth groove for positioning.

[0017] In this invention, the width of the through groove is less than the lateral length of the rotating component.

[0018] In this invention, the support column is provided with a support block and a bearing rod, the bearing rod is provided with a curved extension, the highest point of the curved extension is on the same horizontal plane as the support block, the bearing rod is provided with a first support rod, and the curved extension is provided with a second support rod.

[0019] In this invention, the support assembly includes a support arm, a hinged arm, a movable arm, and a positioning block. The support arm is located at the lower end of the support plate. One end of the support arm is hinged to the hinged arm, and the other end is connected to the support plate and hinged to the movable arm in the middle. One end of the movable arm is hinged to the bearing rod, and the other end is hinged to the support arm. The positioning block is disposed on the movable arm and moves with the movable arm. The positioning block is provided with a support port that cooperates with the second support rod.

[0020] The ceramic embryo drying apparatus of this invention has the following advantages: The apparatus, through its retaining component, can limit the position of the drying movable seat, ensuring it is positioned correctly after being pushed into the drying chamber, preventing positional shifts. It also allows for preparation before pulling out the drying movable seat, preventing accidental pull-out and potential damage to the ceramic products on the support. Furthermore, by changing the position of the support plate, ceramic products of different lengths and heights can be placed on it. The position of the support plate can be adjusted according to the specific ceramic products to be dried, facilitating the drying of ceramic products of different shapes. Finally, it eliminates the need for personnel to enter the drying chamber to place the ceramic products, preventing accidents. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] like Figures 1 to 15 As shown, the ceramic embryo drying device of this invention includes a drying chamber 1, a slide rail 2, a holding assembly 3, a pushing component 4, a drying moving seat 5, and a support 6. The slide rail 2 is used for sliding the drying moving seat 5, allowing it to move between the outside and inside of the drying chamber 1, thereby facilitating the placement of the ceramic products to be dried onto the support plate 44 by the operator. The drying chamber 1 in this application may be equipped with heating wires inside or a blower at the top. The blower blows hot air to dry the ceramic products inside the drying chamber 1. Other structures of the drying chamber 1 are not described in detail in this application, but can be referred to in the prior art.

[0039] The drying chamber 1 is equipped with a door 7, which is hinged to the drying chamber 1. When the drying moving seat 5 moves into the drying chamber 1, it can be sealed through the door 7, which is beneficial for maintaining the temperature.

[0040] In this application, the slide rail 2 is only set on one side of the drying chamber 1. In practice, it can also be set on both sides, so that when one support 6 is drying, the other support 6 can be moved out of the drying chamber 1 to place ceramic embryos, which speeds up the work efficiency, shortens the placement time, and realizes the one-in-one-out design.

[0041] The slide rail 2 is located at the lower end of the drying chamber 1. The slide rail 2 has a groove 8, which restricts the position of the roller 9. Multiple bases 65 are located at the bottom of the slide rail 2 to support it. A through groove 11 is located in the middle of the slide rail 2, extending horizontally to allow the retaining component 3 to rotate within it. The width of the through groove 11 is less than the lateral length of the rotating component 12, allowing the rotating component 12 to extend beyond the through groove 11 in the width direction. This allows the rotating component 12 to be pushed by the pushing component 4, and enables the retaining component 13 to enter the toothed groove 14 to restrict the position of the rack 15, thereby restricting the position of the drying moving seat 5.

[0042] A retaining assembly 3 is provided within the through groove 11, and the retaining assembly 3 is hinged within the through groove 11. The retaining assembly 3 includes a rotating member 12 and a retaining member 13. The middle of the rotating member 12 is hinged within the through groove 11 via a first hinge rod 16, and one end of the rotating member 12 forms an opening groove 17. The retaining member 13 is hinged within the opening groove 17 via a second hinge rod 18. A first reset member 19 is sleeved on the outside of the first hinge rod 16, and a second reset member 20 is sleeved on the outside of the second hinge rod 18. The first reset member 19 and the second reset member 20 have the same structure, only different sizes. The first reset member 19 is used to keep the rotating member 12 in its original position, while the second reset member 20 is used to reset the retaining member 13.

[0043] The rotating member 12 is composed of a hinge part 21 and a pushing part 22. The pushing part 22 is inclined and has a pushing inclined surface 23 that cooperates with the pushing member 4. When the pushing member 4 is pushed, the pushing inclined surface 23 on the rotating member 12 can be pushed, thereby keeping the rotating member 12 rotating around the first hinge rod 16, so that the retaining member 13 is disengaged from the tooth groove 14, and the drying moving seat 5 can be pulled out.

[0044] A first hinge hole 24 is provided in the middle of the hinge portion 21, and a first hinge rod 16 is disposed in the first hinge hole 24. An insertion groove 25 is provided in the first hinge hole 24. The first reset member 19 consists of a positioning section 26 that mates with the insertion groove 25, and symmetrically arranged spiral sections 27 and insertion sections 28. The insertion section 28 is used to limit the movement by mates with the upper and lower inner walls of the through groove 11. The upper and lower interiors of the through groove 11 have small holes that mate with the insertion section 28, so that when the hinge portion 21 is rotated, the spiral section 27 can be twisted, thereby generating a torsional force for reset. During reset, the first reset member 19 mates with the insertion groove 25, and the positioning section 26 pushes the insertion groove 25 to keep the hinge portion 21 rotating and reset.

[0045] The retainer 13 has a second hinge hole 29 in the middle that mates with the second hinge rod 18. An insertion groove 25 is provided inside the second hinge hole 29. The second reset member 20 consists of a positioning section that mates with the insertion groove, and symmetrically arranged spiral and insertion sections. The second reset member 20 has the same function as the first reset member 19, namely, the second reset member 20 is used for the force-induced reset of the retainer 13. The second reset member 20 is disposed in the opening groove 17, and the upper and lower interiors of the opening groove 17 have small holes that mate with the insertion section 28. When the retainer 13 is pushed by the teeth 30, it rotates around the second hinge rod 18. After the retainer 13 rotates, the second reset member 20 is subjected to force, generating a torsional force for reset. After the teeth 30 pass over the retainer 13, the retainer 13 reaches the tooth groove 14, thereby achieving reset under the action of the torsional force, keeping the blocking protrusion 31 and the retaining protrusion 32 in contact.

[0046] The opening groove 17 has a concave arc surface 33, and a blocking protrusion 31 is provided on the concave arc surface 33.

[0047] The retaining member 13 consists of a hinged end 34 and a retaining end 35. The hinged end 34 mates with the concave arc surface 33, and the hinged end 34 is provided with a retaining protrusion 32 that mates with the blocking protrusion 31. The retaining end 35 mates with the toothed groove 14 for limiting the position. The retaining protrusion 32 and the blocking protrusion 31 cooperate with each other to limit the rotation angle of the retaining member 13. Therefore, when the pushing member 4 does not push the rotating member 12 to rotate, the drying moving seat 5 cannot be pulled out. This avoids the drying moving seat 5 being pulled out before it is ready, which would affect the ceramic products on the drying moving seat 5. At the same time, it also plays a safety protection role and avoids accidents.

[0048] Furthermore, the position of component 3 is set at the door 7, which can limit the position of the drying moving seat 5 whether it is inside or outside the drying chamber 1, ensuring that the position of the drying moving seat 5 remains unchanged.

[0049] The pusher 4 is used in conjunction with the retaining assembly 3. The pusher 4 is provided with a strip hole 36, and a bolt 37 that mates with the outer wall of the slide rail 2 is provided in the strip hole 36. The pusher 4 slides at the lower end of the slide rail 2. The retaining pusher 4 moves to the through groove 11 and pushes the retaining assembly 3 to rotate in the through groove 11.

[0050] The pusher 4 consists of a connecting part 38 and moving parts 39 symmetrically arranged at both ends of the connecting part 38. The moving parts 39 are equipped with push rods 40 and slotted holes 36. When the drying moving seat 5 needs to be pulled out, the push rods 40 are pushed first, causing the moving parts 39 to block the through groove 11. During the movement of the moving parts 39, the pusher 22 on the rotating part 12 is pushed, causing the rotating part 12 to rotate around the first hinge rod 16, thus disengaging the retainer 13 from the toothed groove 14. When the retainer 13 disengages from the toothed groove 14, it is blocked by the teeth 30 and rotates around the second hinge rod 18, thus disengaging from the toothed groove 14. After disengaging from the toothed groove 14, the retainer 13 is reset under the influence of the second reset member 20, allowing it to enter the through groove 11 and no longer limit the rack 15.

[0051] After the drying moving seat 5 is pulled out, the push rod 40 is pulled to reset the pusher 4, keeping the moving part 39 from blocking one side of the through groove 11. Therefore, the rotating part 12 will return to its original position under the action of the first reset part 19.

[0052] The drying movable seat 5 is located inside the drying chamber 1. A drying support 6 is mounted on the drying movable seat 5. Symmetrically arranged rollers 9 and connecting blocks 42 are located at the lower end of the drying movable seat 5. The rollers 9 are mounted on the slide rail 2. A rack 15, which cooperates with the retaining component 3, is located at the lower end of the connecting block 42. The rack 15 has multiple teeth 30, which are unidirectional teeth, forming grooves 14 between the teeth 30. The teeth 30 have inclined surfaces facing the drying chamber 1 and horizontal surfaces away from the drying chamber 1, allowing the drying movable seat 5 to be easily pushed into the drying chamber 1. When pulled out, it requires the cooperation of the pushing component 4 to push the rotating component 12 to rotate.

[0053] The drying support 6 is provided with symmetrically arranged pillars 43, support plates 44 and support components 45. The support plates 44 are mounted on the pillars 43 through the support components 45. When the symmetrically arranged support plates 44 are pulled in opposite directions, the support components 45 are kept unfolded, and the distance between the symmetrically arranged support plates 44 is changed.

[0054] When the support plate 44 on the drying bracket 6 works with the support component 45, it can move by pushing it so that the support plate 44 moves closer to each other and down to the lowest point, while pulling it moves the support plate 44 away from each other and up to the highest point. This allows the support plate 44 to stop at the lowest and highest points, changing the distance between the support plate 44 and the lower support plate 44, which is convenient for placing ceramic embryo products of different heights.

[0055] By changing the position of the support plate 44, ceramic products of different lengths and heights can be placed on the support plate 44. The position of the support plate 44 can be adjusted according to the actual ceramic products to be dried, making it convenient to dry ceramic products of different shapes.

[0056] The support plate 44 has bearing portions 66 on both sides that cooperate with the bending extension 47. The bearing portions 66 are used to keep the bending extension in contact with the bearing portion when the two support plates 44 are close to each other, and the bending extension supports the bearing portion 66. Figure 10 and attached Figure 11 The curved extension 47 does not contact the support portion 66 because the support plate 44 is at its highest point, and both support plates 44 are pulled up and moving in opposite directions, thus keeping the curved extension 47 separate from the support portion 66. Only when the support plate 44 is pushed closer to the other support plate 44 will the support plate 44 move downwards and towards the other via the support assembly 45, thereby supporting the support portion 66 through the curved extension 47.

[0057] The support column 43 is equipped with a support block 10 and a bearing rod 46. The bearing rod 46 has a curved extension 47, the highest point of which is on the same horizontal plane as the support block 10. The bearing rod 46 is equipped with a first support rod 48, and the curved extension 47 is equipped with a second support rod 49. When the symmetrically arranged support plates 44 move closer to each other, the support plates 44 are kept on the support block 10 and the curved extension 47, and are supported by the support block 10 and the curved extension 47.

[0058] The symmetrically arranged support plates 44 have no edges on one side facing each other, while the other three sides have edges. The ceramic products on the support plates 44 are restricted by the other three sides. The absence of edges allows the symmetrically arranged support plates 44 to be used in conjunction with each other.

[0059] The support assembly 45 includes a support arm 50, a hinged arm 51, a movable arm 52, and a positioning block 53. The support arm 50 is located at the lower end of the support plate 44. One end of the support arm 50 is hinged to the hinged arm 51, and the other end is connected to the support plate 44. It is also hinged to the movable arm 52 in the middle. One end of the movable arm 52 is hinged to the bearing rod 46, and the other end is hinged to the support arm 50. The positioning block 53 is set on the movable arm 52 and moves with the movable arm 52. The positioning block 53 is provided with a support port 54 that cooperates with the second support rod 49.

[0060] One end of the hinged arm 51 is hinged to the bearing rod 46 via the first support rod 48. The hinged arm 51 and the support arm 50 are hinged together via the third hinge rod 55. One end of the movable arm 52 is hinged to the support arm 50 via the fourth hinge rod 56, and the other end is hinged to the bearing rod 46 via the fifth hinge rod 57. The positioning block 53 is positioned between the two movable arms 52 via the fifth hinge rod 57 and the positioning rod 58, so that the positioning block 53 and the movable arm 52 can remain stationary and rotate together with the movable arm 52.

[0061] The articulated arm 51 consists of an arc-shaped section 59 and a rotating section 60. The arc-shaped section 59 is used to enable the articulated arm 51 to cooperate with the movable arm 52, and at the same time, it is convenient for the staff to pull or push the support plate 44 so that the entire support assembly 45 can rotate.

[0062] The movable arm 52 consists of a fixed section 61 and a clearance section 62. The clearance section 62 is arc-shaped, and a clearance area 63 is formed in the middle of the clearance section 62 to avoid the rotating section 60.

[0063] The positioning block 53 is provided with a fixed end 67 that cooperates with the fixed section 61, as well as a first positioning arm 68 and a second positioning arm 64, and the support opening 54 is formed between the first positioning arm 68 and the second positioning arm 64.

[0064] When the symmetrically arranged support plates 44 are pulled out, their height increases, thereby changing the height between support plate 44 and the next support plate 44, facilitating the placement of ceramic products of different heights. Furthermore, due to the cooperation of the positioning block 53, the positioning block 53 acts on the second support rod 49, bearing the pressure from the ceramic products on the support plate 44.

[0065] When the support plate 44 is pulled, the hinge arm 51 rotates around the third hinge rod 55 and the movable arm 52 rotates around the fifth hinge rod 57. Due to the limiting of the hinge arm 51 and the movable arm 52, the support arm 50 can be kept in a horizontal state, and it will move up and down due to the rotation of the hinge arm 51 and the movable arm 52. However, during the movement and rotation, the support arm 50 is always kept facing upward to maintain the stability of the support plate 44.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
