Description

Technical Field

[0001] This invention relates to the field of foamed ceramic fabric technology, and in particular to a foamed ceramic fabric equipment and fabrication method. Background Technology

[0002] Foamed ceramic powder feeding equipment is typically used to feed foamed ceramic powder, which is then sintered into foamed ceramic sheets. Traditional foamed ceramic powder feeding equipment usually includes a hopper and a feeding frame. Before feeding, the hopper feeds the powder into the feeding frame. The feeding frame then moves on a cart, simultaneously feeding more powder onto the cart. Feeding is complete once the feeding frame reaches the end of the cart. While this type of equipment has a simple structure, traditional methods result in a high feeding height, more air within the powder, a lower powder density, and a lower overall thermal conductivity. This necessitates a longer sintering time to obtain a qualified finished product, thus extending the production cycle and increasing the length of the firing zone, ultimately raising the unit energy consumption of the foamed ceramic products. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a foamed ceramic fabrication equipment that can reduce the air in the powder during fabrication, improve the thermal conductivity of the powder, thereby shortening the firing time and reducing the unit production cost of foamed ceramic products. To solve the above-mentioned technical problems, the present invention provides a foamed ceramic fabric feeding device, including a storage hopper, a fixed frame, a movable frame, and a discharge frame. The storage hopper is located above the discharge frame, and a first gate is provided at the bottom of the storage hopper. The movable frame is movably connected to the fixed frame and can move horizontally on the fixed frame. The discharge frame is movably connected to the movable frame and can move vertically on the movable frame. A second gate is provided at the bottom of the discharge frame.

[0004] It also includes a vibration mechanism, which includes a vibration drive and a vibration rod. The vibration drive is connected to the vibration rod, and the vibration rod can be moved to the bottom of the discharge frame. The vibration drive can drive the vibration rod to vibrate in the powder at a preset frequency when the moving frame moves. The preset frequency range is 50-200Hz.

[0005] As an improvement to the above solution, the vibrating rod is horizontally arranged on the side of the discharge frame, and the middle part of the vibrating rod is connected to the vibration driving component through a connecting rod. The foamed ceramic fabrication equipment also includes a lifting mechanism, which includes a first lifting driving component, a first transmission rod, and a lifting sleeve. The first lifting driving component is driven by the first transmission rod. The lifting sleeve is sleeved on the outside of the first transmission rod and fixed to the discharge frame. The first transmission rod is vertically arranged at both ends of the vibrating rod. When the first lifting driving component drives the first transmission rod to move vertically relative to the lifting sleeve, the connecting rod can drive the vibrating rod to move vertically. The vibration driving component can drive the vibrating rod to vibrate through the connecting rod.

[0006] As an improvement to the above solution, the foamed ceramic fabric equipment further includes a connecting mechanism, which is located between the vibrating rod and the first transmission rod. The vibrating rod is fixed to the bottom of the connecting mechanism, and the top of the connecting mechanism is hinged to the bottom of the first transmission rod. The first transmission rod can drive the connecting mechanism to move vertically.

[0007] As an improvement to the above solution, the lifting mechanism further includes a second lifting drive component and a second transmission rod component. The second lifting drive component is connected to the second transmission rod component. The second transmission rod component is vertically disposed at both ends of the vibrating rod. The first transmission rod component is sleeved outside the second transmission rod component. The second lifting drive component can drive the second transmission rod component to move vertically relative to the first transmission rod component.

[0008] As an improvement to the above solution, the connecting mechanism includes a swing arm and a connecting sleeve. The middle part of the swing arm is hinged to the bottom of the first transmission rod. The lower part of the swing arm is fixed to the upper part of the connecting sleeve. The lower part of the connecting sleeve is fixed to the end of the vibrating rod. The upper part of the swing arm can abut against the bottom end of the second transmission rod. The swing arm is inclined and gradually tilts from top to bottom towards the side closer to the vertical central axis of the discharge frame. When the second transmission rod moves vertically, it can drive the connecting sleeve to swing towards or away from the discharge frame.

[0009] As an improvement to the above solution, the vibration rod includes a middle section located in the middle and an end section located at the end, with a transition section between the middle section and the end section. The diameter of the middle section is smaller than the diameter of the end section, and the diameter of the transition section increases from the middle section toward the end section assembly.

[0010] The present invention also provides a method for fabric application in the foamed ceramic fabric application equipment described above, comprising the following steps: Before the material is laid, the material cart moves to the bottom of the discharge frame and opens the first gate of the storage hopper. The powder falls from the storage hopper into the discharge frame, which is located at a first horizontal preset position. During material feeding, the first gate is closed, the discharge frame descends within the movable frame, and the vibrating rod descends to the first vibration position. Then, the second gate of the discharge frame is opened, and the powder falls from the discharge frame into the material cart. The vibration drive unit drives the vibrating rod to vibrate within the powder at a preset frequency, the preset frequency being 50-200Hz. Simultaneously, the movable frame moves the discharge frame horizontally on the fixed frame. After the fabric is laid, the material cart leaves.

[0011] As an improvement to the above solution, the following steps are also included: During the vibration of the vibrating rod in the powder, the discharge frame moves horizontally to the second preset horizontal position, and the vibrating rod moves from the first vibration position to the second vibration position; Then, the first transmission rod pushes the swing arm to swing the swing arm toward the vertical central axis of the discharge frame. The vibrating rod continues to vibrate and moves from the second vibration position to the third vibration position. At the same time, the second gate is closed, and the vibrating rod vibrates in the powder below the second gate.

[0012] As an improvement to the above solution, the steps after completing the fabric also include: The vibrating rod gradually reduces its amplitude and stops vibrating at the third vibration position. After the vibration stops, the discharge frame rises and returns to the first horizontal preset position, and then the vibrating rod returns to its original position.

[0013] Implementing this invention has the following beneficial effects: This invention relates to a foamed ceramic material feeding device comprising a storage hopper, a fixed frame, a movable frame, a discharge frame, and a vibration mechanism. The storage hopper is located above the discharge frame and is used to release material into the discharge frame. After the powder falls into the discharge frame, it is distributed by the discharge frame. During the distribution process, the vibration drive of the vibration mechanism drives a vibrating rod to extend into the powder below the discharge frame. During distribution, the movable frame moves the discharge frame horizontally on the fixed frame. The vibrating rod vibrates within the powder at a preset frequency, ranging from 50-200Hz. High-frequency vibration reduces the gaps between powder particles, expelling air and increasing the powder's specific gravity. The reduced air volume increases the overall thermal conductivity of the powder, improving thermal efficiency. Therefore, during sintering, the sintering time can be shortened. This shortens the production cycle, increases production efficiency, and reduces the length of the firing zone, thereby lowering the unit production cost of foamed ceramic products.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0016] See Figure 1 and Figure 2The first embodiment of this invention discloses a foamed ceramic material feeding device, including a storage hopper 1, a fixed frame 2, a movable frame 3, and a discharge frame 4. The storage hopper 1 is located above the discharge frame 4 and is used to replenish powder to the discharge frame 4. The fixed frame 2 is fixed in a platform, and the discharge frame 4 is located on the movable frame 3. The movable frame 3 can drive the discharge frame 4 to move. The bottom of the storage hopper 1 is provided with a first gate 11. When replenishing powder, the first gate 11 opens, and the powder falls from the storage hopper 1 into the discharge frame 4. The movable frame 3 is movably connected to the fixed frame 2 and can move horizontally on the fixed frame 2 to drive the discharge frame 4 to move horizontally on a material cart 10. The discharge frame 4 is movably connected to the movable frame 3. See also... Figure 6 The discharge frame 4 can move vertically on the movable frame 3, and the bottom of the discharge frame 4 is provided with a second gate 41. (See attached image) Figure 7 During the feeding process, the second gate 41 opens, and the powder falls from the discharge frame 4 into the material cart 10.

[0017] The foamed ceramic fabrication equipment also includes a vibration mechanism 5 for vibrating the powder after it has been fed. The vibration mechanism 5 includes a vibration drive 51 and a vibration rod 52. The vibration drive 51 is connected to the vibration rod 52. During fabrication, the vibration rod 52 can move to the bottom of the discharge frame 4. As the powder falls from the discharge frame 4 into the trolley 10, the vibration drive 51 can drive the vibration rod 52 to vibrate in the powder when the moving frame 3 moves, and vibrate at a preset frequency. The preset frequency range is 50-200Hz. Through vibration, the gap between the powder particles can be reduced, and the air between the powder particles can be discharged, thereby increasing the specific gravity of the powder. Due to the reduction of air, the overall thermal conductivity of the powder increases, thereby improving the thermal conductivity efficiency.

[0018] The foaming ratio of ordinary specific gravity foamed ceramics is about 2.0, which means that if the material is 5 cm thick, the thickness after firing is about 10 cm. Taking a 10 cm slab as an example, the material thickness of traditional foamed ceramic material feeding equipment is about 5.5 to 6.0 cm. The thermal conductivity of the powder after feeding is about 0.27, and the firing thickness is about 11 to 12 cm. After being leveled by a scraper, a 10 cm slab is obtained. The firing cycle of a traditional kiln is generally 11 to 12 hours, and the gas consumption per unit product is about 100 cubic meters. In this embodiment of the invention, high-frequency vibration (frequency 50-200Hz) can reduce the thickness of the powder from the traditional 5.5 cm to about 4.5 cm. This is equivalent to reducing the air between the powder particles by 1 cm. The reduced gas volume between the powder particles increases the specific gravity of the powder, and the thermal conductivity of the powder after spreading increases to about 0.32. This increases the heat transfer efficiency of the powder, resulting in a shorter firing time and a shorter firing zone. According to calculations, taking a 10 cm plate as an example, the firing time of this embodiment of the invention can be shortened by 30%-40%, and the firing zone can be shortened by 35%-45%.

[0019] The beneficial effects of the first embodiment of the present invention are as follows: The first embodiment of the foamed ceramic feeding device of the present invention includes a storage hopper 1, a fixed frame 2, a movable frame 3, a discharge frame 4, and a vibration mechanism 5. The storage hopper 1 is located above the discharge frame 4 and is used to discharge powder into the discharge frame 4. After the powder falls into the discharge frame 4, it is distributed by the discharge frame 4. During the distribution process, the vibration drive 51 of the vibration mechanism 5 can drive the vibration rod 52 to extend into the powder below the discharge frame 4. During distribution, the movable frame 3 can move the discharge frame 4 relative to the fixed frame 2. The vibrating rod 52 moves horizontally and vibrates in the powder at a preset frequency, which is in the range of 50-200Hz. Vibration can reduce the gap between powder particles and expel air between them, thereby increasing the specific gravity of the powder. Due to the reduction of air, the overall thermal conductivity of the powder increases, thereby improving the thermal conductivity. Therefore, in sintering, the sintering time of the powder can be shortened. While shortening the production cycle and improving production efficiency, the length of the firing zone can also be shortened, thereby reducing the unit production cost of foamed ceramic products.

[0020] Specifically, see Figure 2The vibrating rod 52 is horizontally positioned on the side of the discharge frame 4. The length of the vibrating rod 52 spans both sides of the material cart 10. The middle part of the vibrating rod 52 is connected to the vibrating drive component 51 via a connecting rod 53. The vibrating drive component 51 generates vibration, which is transmitted to the vibrating rod 52 via the connecting rod 53. The connecting rod 53 is vertically connected to the middle part of the vibrating rod 52. The foamed ceramic fabric feeding device also includes a lifting mechanism 6. The lifting mechanism 6 includes a first lifting drive component 61, a first transmission rod 62, and a lifting sleeve 63. The lifting mechanism 6 is preferably positioned on both sides of the connecting rod 53, enabling simultaneous vibration at both ends of the vibrating rod 52. The lifting mechanism is configured with the first lifting drive component 61 and the first transmission rod 62 in a transmission arrangement. The first lifting drive component 61 can be a cylinder, motor, or other components. The first transmission rod 62 can be a lead screw, rotating sleeve, smooth rod, or other components. The lifting sleeve 63 is sleeved around the first transmission rod 62 and fixed to the discharge frame 4. When the first transmission rod 62 is a lead screw, the inner wall of the lifting sleeve 63 has threads, and the first transmission rod 62 lifts and lowers by rotating within the lifting sleeve 63. When the first transmission rod 62 is a smooth rod, the inner wall of the lifting sleeve 63 has no threads, and the first transmission rod lifts and lowers directly within the lifting sleeve 63. The lifting sleeve 63 can guide and limit the first transmission rod 62, ensuring that the first transmission rod 62 can move in the vertical direction. The first transmission rod 62 is vertically arranged at both ends of the vibrating rod 52. When the first lifting drive 61 drives the first transmission rod 62 to move vertically relative to the lifting sleeve 63, the connecting rod 53 can drive the vibrating rod 52 to move vertically. The vibration drive 51 can drive the vibrating rod 52 to vibrate through the connecting rod 53.

[0021] The vibration source of the vibrating rod 52 is located in the middle of the vibrating rod 52. The vibration in the middle of the vibrating rod 52 is transmitted to both ends. However, due to the connection of the first transmission rod 62, the amplitude at both ends of the vibrating rod 52 is limited. In order to make the two ends of the vibrating rod 52 have a larger amplitude for more efficient vibration of the powder, see [reference needed]. Figure 3In the second embodiment, the foamed ceramic fabric equipment further includes a connecting mechanism 7. The connecting mechanism 7 is located between the vibrating rod 52 and the first transmission rod 62. Specifically, the connecting mechanism 7 is located between the end of the vibrating rod 52 and the bottom of the first transmission rod 62. The vibrating rod 52 is fixed to the bottom of the connecting mechanism 7, and the top of the connecting mechanism 7 is hinged to the bottom of the first transmission rod 62. The first transmission rod 62 can drive the connecting mechanism 7 to move vertically. The connecting mechanism 7 connects the vibrating rod 52 and the first transmission rod 62. The connection of the connecting mechanism 7 is a flexible connection. When the vibration in the middle of the vibrating rod 52 is transmitted to both ends of the vibrating rod 52, due to the flexible connection of the connecting mechanism 7, the vibration amplitude at both ends of the vibrating rod 52 will be greater than that of a rigid connection, thereby allowing the powder at both ends of the vibrating rod 52 to vibrate normally and expel air.

[0022] Furthermore, in the second embodiment, the lifting mechanism 6 further includes a second lifting drive member 64 and a second transmission rod member 65. The second lifting drive member 64 is connected to the second transmission rod member 65. The second transmission rod member 65 is vertically disposed at both ends of the vibrating rod 52. The first transmission rod member 62 is sleeved outside the second transmission rod member 65. The second lifting drive member 64 can be a cylinder, a motor, or other components. The second transmission rod member 65 can be a lead screw, a rotating sleeve, a smooth rod, or other components. In this embodiment, the first transmission rod member 62 is a rotating sleeve, which can rotate and lift within the lifting sleeve 63. The first transmission rod member 62 has a thread inside. The second transmission rod member 65 is a lead screw, which can rotate and lift within the first transmission rod member 62. Therefore, the first transmission rod member 62 can drive the second transmission rod member 65 to move up and down relative to the lifting sleeve 63, and the second lifting drive member 64 can drive the second transmission rod member 65 to move vertically relative to the first transmission rod member 62.

[0023] Among them, see Figure 4In the second embodiment, the connecting mechanism 7 includes a swing arm 71 and a connecting sleeve 72. The middle part of the swing arm 71 is hinged to the bottom of the first transmission rod 62, the lower part of the swing arm 71 is fixed to the upper part of the connecting sleeve 72, and the lower part of the connecting sleeve 72 is fixed to the end of the vibration rod 52. Therefore, the connecting mechanism 7 can connect the end of the first transmission rod 62 and the end of the vibration rod 52. Under normal circumstances, the swing arm 71 can swing at a certain angle relative to the bottom of the first transmission rod 62, so that the end of the connecting sleeve 72 and the end of the vibration rod 52 have a certain degree of freedom. After the second transmission rod 65 is screwed in to a certain depth, the upper part of the swing arm 71 can abut against the bottom end of the second transmission rod 65.

[0024] See Figure 3 , Figure 8 and Figure 9 During material feeding, the moving frame 3 drives the discharge frame 4 to move horizontally above the material cart 10. The vibrating rod 52 vibrates the powder falling on the material cart 10. After the moving frame 3 moves to the other side of the material cart 10, since the vibrating rod 52 is located on one side of the discharge frame 4, there is still a certain distance between the vibrating rod 52 and the edge of the material cart 10. This distance will form a vibration blind zone. The vibrating rod 52 cannot vibrate the powder in the corner of the material cart 10 (which is also the powder located directly below the second gate 41). In order to vibrate the powder in this area and achieve a uniform vibration effect, the swing rod 71 is inclined. The swing rod 71 gradually tilts from top to bottom towards the side closer to the vertical central axis of the discharge frame 4. This setting allows the second transmission rod 65 to drive the connecting sleeve 72 to swing towards or away from the discharge frame 4 when moving vertically. Specifically, when the second transmission rod 65 descends, the lower part of the swing rod 71 will move closer to the discharge frame 4, thereby causing the bottom of the connecting sleeve 72 to move the vibrating rod 52 to below the second gate 41. The vibrating rod 52 can then vibrate the powder at that location to expel air from the vibration blind zone and improve the uniformity of the powder's specific gravity. To enable the swinging of the vibrating rod 52, a hinged connection can be used between the vibrating rod 52 and the connecting rod 53.

[0025] Furthermore, since the vibration source is located in the middle of the vibrating rod 52, the vibration frequency and amplitude differ between the middle and both ends of the vibrating rod 52. The vibration energy attenuates from the middle towards both ends of the vibrating rod 52, but the amplitude increases from the middle towards both ends. Therefore, in actual vibration, the actual vibration effect on the powder in each area of ​​the material cart 10 is not uniform. (See [reference]). Figure 5In the third embodiment, in order to obtain a more uniform vibration effect for the powder in each area of ​​the material cart 10, the vibrating rod 52 is divided into an intermediate section 521 located in the middle and an end section 522 located at the end. A transition section 523 is provided between the intermediate section 521 and the end section 522. The diameter of the intermediate section 521 is smaller than the diameter of the end section 522, and the diameter of the transition section 523 increases from the intermediate section 521 toward the end section 522. The diameter of the vibrating rod 52 gradually increases from the middle to both ends. The middle section 521 has a smaller diameter and lower inertia, which helps ensure that the vibration energy is transmitted more directly and efficiently to the transition section 523, reducing energy loss during transmission. The gradually increasing diameter of the transition section 523 increases its stiffness and strength, enabling it to withstand greater amplitude and vibration force. The larger diameter of the end section 522 increases the cross-sectional area and mass of the vibrating joint, thereby increasing inertia and weakening the phenomenon of the amplitude gradually increasing from the middle to both ends. This ensures that the amplitude of the vibrating rod 52 in the middle and at both ends is within a relatively uniform range. By setting the diameter variation of the vibrating rod 52, the vibration energy and amplitude in the middle and at both ends of the vibrating rod 52 can be balanced, thereby improving the uniformity of the actual vibration effect on the powder in each area of ​​the material cart 10.

[0026] See Figures 6-10 The present invention also discloses a fabric application method, applied to the foamed ceramic fabric application equipment described above, comprising the following steps: S01, before the material is laid, the material cart 10 runs to the bottom of the discharge frame 4 and opens the first gate 11 of the storage hopper 1. The powder falls from the storage hopper 1 into the discharge frame 4, and the discharge frame 4 is located at the first horizontal preset position. S02, during material feeding, the first gate 11 is closed, the discharge frame 4 descends within the movable frame 3, the vibrating rod 52 descends to the first vibration position, and then the second gate 41 of the discharge frame 4 is opened, and the powder falls from the discharge frame 4 into the material cart 10. The vibration drive 51 drives the vibrating rod 52 to vibrate, and the vibrating rod 52 vibrates in the powder at a preset frequency, the preset frequency being 50-200Hz. At the same time, the movable frame 3 drives the discharge frame 4 to move horizontally on the fixed frame 2. S03, after the fabric is laid, the vibrating rod 52 and the discharge frame 4 rise, and the material cart 10 leaves.

[0027] As the moving frame 3 drives the discharge frame 4 to move horizontally on the fixed frame 2, the vibrating rod 52 vibrates at a preset frequency, continuously vibrating and tapping the powder falling into the material cart 10. This causes air to escape from the powder, reducing the gaps between powder particles and increasing the overall thermal conductivity of the powder, thereby improving thermal efficiency. Therefore, during sintering, the sintering time of the powder can be shortened. This shortens the production cycle, improves production efficiency, and reduces the length of the firing zone, thus lowering the unit production cost of foamed ceramic products. According to calculations, taking a 10cm plate as an example, the firing time in this embodiment of the invention can be shortened by 30%-40%, and the firing zone can be shortened by 35%-45%.

[0028] Additionally, during material distribution, the movable frame 3 drives the discharge frame 4 to move horizontally above the material cart 10. The vibrating rod 52 vibrates the powder falling onto the material cart 10. After the movable frame 3 moves to the other side of the material cart 10, since the vibrating rod 52 is located on one side of the discharge frame 4, there is still a certain distance between the vibrating rod 52 and the edge of the material cart 10. This distance creates a vibration blind zone, and the vibrating rod 52 cannot vibrate the powder in the corner of the material cart 10 (which is also the powder located directly below the second gate 41). In order to vibrate the powder in this area and achieve a uniform vibration effect, the following steps are also included during material distribution: See Figure 11 S21, during the vibration of the vibrating rod 52 in the powder, the discharge frame 4 moves horizontally to the second horizontal preset position, and the vibrating rod 52 moves from the first vibration position to the second vibration position; then the first transmission rod 62 pushes the swing rod 71 to swing the swing rod towards the vertical central axis of the discharge frame 4, the vibrating rod 52 continues to vibrate and moves from the second vibration position to the third vibration position, and at the same time closes the second gate 41, the vibrating rod 52 vibrates in the powder below the second gate 41.

[0029] There is a certain distance between the second vibration position and the edge of the material cart 10, which forms a vibration blind zone. The powder in the vibration blind zone has a high air content and thickness. Then, the first transmission rod 62 pushes the swing rod 71 to swing the swing rod towards the vertical central axis of the discharge frame 4. The vibration rod 52 maintains vibration and moves from the second vibration position to the third vibration position. The third vibration position is located directly below the discharge frame 4, specifically below the second gate 41 and close to the edge of the material cart 10. Then, the vibration rod 52 vibrates and beats the powder at this position, which can ensure that the powder in each area of ​​the material cart 10 can obtain a more consistent vibration effect.

[0030] Additionally, see Figure 12 The steps after completing the fabric also include: S31, the vibrating rod 52 gradually reduces the amplitude at the third vibration position and stops vibrating. After the vibration stops, the discharge frame 4 rises and resets to the first horizontal preset position, and then the vibrating rod 52 resets.

[0031] The gradually decreasing amplitude of the vibrating rod 52 can reduce local stress or excessive dispersion caused by excessive stirring, thereby ensuring the normal sintering of the powder in the subsequent process.

[0032] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.

A method for applying a foamed ceramic fabric equipment as described in any one of claims 1-6, characterized in that, Includes the following steps: Before the material is laid, the material cart moves to the bottom of the discharge frame and opens the first gate of the storage hopper. The powder falls from the storage hopper into the discharge frame, which is located at a first horizontal preset position. During the feeding process, the first gate is closed, the discharge frame descends within the movable frame, the vibrating rod descends to the first vibration position, and then the second gate of the discharge frame is opened, allowing the powder to fall from the discharge frame into the material cart. The vibration drive drives the vibrating rod to vibrate in the powder at a preset frequency, the preset frequency being in the range of 50-200Hz. Simultaneously, the movable frame drives the discharge frame to move horizontally on the fixed frame. After the fabric is laid, the material cart leaves.

8. The fabric preparation method according to claim 7, characterized in that, The following steps are also included when processing the fabric: During the vibration of the vibrating rod in the powder, the discharge frame moves horizontally to the second preset horizontal position, and the vibrating rod moves from the first vibration position to the second vibration position; Then, the first transmission rod pushes the swing arm to swing the swing arm toward the vertical central axis of the discharge frame. The vibrating rod continues to vibrate and moves from the second vibration position to the third vibration position. At the same time, the second gate is closed, and the vibrating rod vibrates in the powder below the second gate.

9. The fabric application method according to claim 8, characterized in that, The steps after completing the fabric include: The vibrating rod gradually reduces its amplitude and stops vibrating at the third vibration position. After the vibration stops, the discharge frame rises and resets to the first horizontal preset position, and then the vibrating rod resets.
