Description

Technical Field

[0001] The present invention belongs to the technical field of manufacturing special equipment for ceramic product production, and specifically relates to a ceramic product pressing device. Background Art

[0002] Ceramic dry pressing forming is a process in which ceramic powder is formed into a green body with a certain shape and strength by applying pressure in a mold. This process includes powder preparation, adding binder, granulation, pressing, drying and sintering. Among them, the pressing process is to put raw material powder particles into the mold of the pressing device, and by applying pressure to the raw material powder particles in the mold, the raw material powder particles are pressed into ceramic products.

[0003] The patent with publication number CN219820054 discloses a ceramic forming press for convenient material taking, including a machine base. Two groups of side plates are symmetrically arranged on the machine base. A support plate is fixedly installed on the two groups of side plates. A hydraulic cylinder is fixedly installed on the support plate. The output end of the hydraulic cylinder is provided with a mounting plate. A moving mold is installed on the mounting plate. A disc is arranged below the moving mold. The disc is rotatably installed on the machine base. Three groups of static molds are arranged at equal angles on the disc. Through the mutual cooperation of the machine base, side plates, support plate, hydraulic cylinder, mounting plate, moving mold, extension plate, disc, mounting groove, and static mold, this solution can form three working positions through the rotation design of three static molds cooperating with the disc, and can synchronously perform feeding, material taking and pressing work, effectively reducing time waste and being beneficial to improving the overall efficiency. Moreover, the shaped product can be transferred to the outside of the machine base and the support plate for material taking, which is beneficial to improving the convenience of material taking.

[0004] In the above solution, loading the static mold requires manual operation by workers, which reduces the automation rate of the device. Secondly, during the unloading process, the static mold needs to rotate to the position of the electric push rod, and the ceramic product is demolded by the electric push rod pushing the T-shaped ejector rod, completing the unloading of the ceramic product. This process requires the power provided by the electric push rod, increasing the equipment cost investment of the device. Therefore, the present invention provides a ceramic product pressing device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A ceramic product pressing device of the present invention includes a frame. A first support frame and a second support frame are sequentially arranged on the frame. A powder box is fixedly installed on the first support frame. A hydraulic cylinder for driving a moving mold is fixedly installed on the second support frame. Two groups of transmission shafts are rotatably installed in the frame. Driving sprockets are installed at both ends of the transmission shafts. Two groups of driving sprockets respectively engage two groups of chains. A number of static molds are arranged around the two groups of chains. A conveyor belt mechanism is arranged below the number of static molds. The static mold includes a mold body. Both ends of the mold body are respectively connected to the two groups of chains. A pressing groove is opened on the mold body. A movable block is movably inserted into the pressing groove. Two guide posts are slidably connected to the movable block. The upper ends of the guide posts are fixedly connected to the mold body. A first spring is sleeved on the guide posts. A roller is rotatably installed at the lower end of the movable block. A support plate is arranged in the number of static molds. Both ends of the support plate are respectively rotatably connected to the two support plates. The roller is in rolling connection with the outer ring of the support plate. A convex block for pushing the roller is arranged on the support plate. The lower end of the powder box is attached to the upper end surface of a mold body. Two guide holes are symmetrically opened on the second support frame. A guide rod is movably inserted into the guide hole. The lower end of the guide rod is fixedly connected to the moving mold. A vibration motor is arranged at the upper end of the powder box; As the number of static molds makes a circular motion, the powder in the powder box can automatically enter the pressing groove of the mold body, realizing automatic feeding and improving the automation rate of the device. Secondly, by the convex block squeezing the roller, the ceramic product in the pressing groove is automatically pushed out by the movable block. The convex block replaces the power equipment to provide the feeding power, thereby reducing the equipment cost investment of the device.

[0007] Preferably, a powder removing mechanism is arranged between the first support frame and the second support frame. The powder removing mechanism includes a blanking box. The blanking box is fixedly installed on one side of the frame. A fixed seat fixedly installed in the frame. A rotating shaft rotatably connected to the fixed seat. Six scraping handles equally angularly installed on the rotating shaft. A rubber scraping plate installed on the scraping handle. A first bevel gear installed at the lower end of the rotating shaft. A second bevel gear meshing with the first bevel gear. One end of the driven shaft is connected to the second bevel gear. The other end of the driven shaft is connected to a driven sprocket. The driven sprocket engages a group of chains. The driven shaft is rotatably installed on the frame. Dumping plates are symmetrically arranged on both sides of the frame. A material receiving box is arranged on one side of a group of dumping plates. The other group of dumping plates is located above the blanking box; As the rubber scraping plate rotates, the rubber scraping plate will slide along the upper end surface of the moving mold body, so that the powder on the upper end surface of the mold body is scraped off by the rubber scraping plate. Part of the powder will fall into the material receiving box along a group of dumping plates. The other part of the powder will be scraped by the rubber scraping plate to the other group of dumping plates and fall into the blanking box along the other group of dumping plates, realizing the cleaning of the powder on the mold body and achieving the purpose of saving resources.

[0008] The swivel joint of the second end of the spring is fixedly connected to the end of the handle, and the other end is fixedly connected to the second end of the handle by a spring. As the sleeve slides along the second annular surface, the rubber scraper will rub against the brush, so that the brush will clean off the powder attached to the rubber scraper. Since several groups of grooves are distributed on the second annular surface, when the sleeve enters the groove, the handle will continue to slide along the fixed tube toward the rotating shaft, and the pin will slide along the linear groove. When the sleeve is staggered from the groove, the handle will continue to slide along the fixed tube away from the rotating shaft, so that the pin returns to the intersection of the spiral groove and the linear groove. Since there are multiple groups of grooves distributed on the second annular surface, the rubber scraper moves back and forth along the axial direction of the handle, thereby increasing the friction between the rubber scraper and the brush, so that the powder on the rubber scraper is cleaned more cleanly by the brush, thereby achieving the cleaning of the rubber scraper and increasing the service life of the rubber scraper.

[0009] The beneficial effects of the present invention are as follows: 1. As several groups of static molds make circular motions, the powder in the powder box can automatically enter the pressing groove of the mold body to realize automatic loading and improve the automation rate of the device. Secondly, the convex block squeezes the roller so that the ceramic products in the pressing groove are automatically ejected by the movable block. The convex block replaces the power equipment to provide the unloading power, thereby reducing the equipment cost investment of the device.

[0010] 2. When the rubber scraper is scraping off the powder on the mold body, the rubber scraper is perpendicular to the mold body, the sleeve on the handle will roll along the first ring surface on the guide ring, and the second spring is in a stretched state. When the rubber scraper is offset from the mold body, the sleeve rolls from the first ring surface to the second ring surface. Since the radius of the second ring surface is smaller than the radius of the first ring surface, under the rebound force of the second spring, the second spring will pull the handle to slide along the fixed tube, and at the same time, the handle drives the pin to slide along the spiral groove. Under the guidance of the spiral groove, the handle and the rubber scraper are rotated 90 degrees so that the rubber scraper is parallel to the upper end surface of the mold body. At this time, the pin is located at the intersection of the spiral groove and the linear groove. As the sleeve slides along the second ring surface, the rubber scraper will rub against the brush, so that the brush will clean up the powder attached to the rubber scraper.

[0011] 3. Since several groups of grooves are distributed on the second annular surface, when the sleeve enters the groove, the handle rod will continue to slide along the fixed tube toward the rotating shaft, and the pin will slide along the linear groove. When the sleeve is staggered from the groove, the handle rod will continue to slide along the fixed tube away from the rotating shaft, so that the pin will return to the intersection of the spiral groove and the linear groove. Since there are multiple groups of grooves distributed on the second annular surface, the rubber scraper moves back and forth along the axial direction of the handle rod, thereby increasing the friction between the rubber scraper and the brush, so that the powder on the rubber scraper is cleaned more cleanly by the brush, thereby realizing the cleaning of the rubber scraper and improving the service life of the rubber scraper.

Specific Embodiments

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Embodiment 1: As Figures 1 to 4As shown in the figure, a ceramic product pressing device according to an embodiment of the present invention includes a frame 1. A first support frame 2 and a second support frame 3 are sequentially arranged on the frame 1. A powder box 4 is fixedly installed on the first support frame 2. A hydraulic cylinder 5 for driving a moving die 6 is fixedly installed on the second support frame 3. Two groups of transmission shafts 7 are rotatably installed in the frame 1. Active sprockets 8 are installed at both ends of the transmission shaft 7. Two groups of active sprockets 8 respectively engage two groups of chains 9. A number of static dies 10 are arranged around the two groups of chains 9. A conveyor belt mechanism 11 is arranged below the number of static dies 10. The static die 10 includes a die body 101. Both ends of the die body 101 are respectively connected to the two groups of chains 9. A pressing groove 102 is opened on the die body 101. A movable block 103 is movably inserted into the pressing groove 102. Two guide posts 104 are slidably connected to the movable block 103. The upper ends of the guide posts 104 are fixedly connected to the die body 101. A first spring 105 is sleeved on the guide posts 104. A roller 106 is rotatably installed at the lower end of the movable block 103. A support plate 71 is arranged in the number of static dies 10. Both ends of the support plate 71 are respectively rotatably connected to the two groups of support plates 71. The roller 106 is in rolling connection with the outer ring of the support plate 71. A convex block 72 for pushing the roller 106 is arranged on the support plate 71. The lower end of the powder box 4 abuts against the upper end surface of a die body 101. Two guide holes 31 are symmetrically opened on the second support frame 3. A guide rod 32 is movably inserted into the guide hole 31. The lower end of the guide rod 32 is fixedly connected to the moving die 6. A vibration motor 401 is arranged at the upper end of the powder box 4.

[0025] Specifically, the powder box 4 stores powder raw materials. In the initial state, the lower end of the powder box 4 faces a die body 101. The pressing groove 102 of this die body 101 is filled with powder raw materials. The moving die 6 faces the pressing groove 102 on another die body 101. When it is necessary to press a ceramic product, a group of transmission shafts 7 are driven to rotate by a motor. This transmission shaft 7 drives the two groups of active sprockets 8 to rotate. The two groups of active sprockets 8 drive the two groups of chains 9 and a number of static dies 10 to perform a circular motion. Attached Figure 1The direction indicated by the middle arrow is the circular motion direction, so that the mold body 101 is staggered from the lower end of the powder box 4, and at the same time, the next group of mold bodies 101 are facing the lower end of the powder box 4. In this process, the rollers 106 on some static molds 10 roll along the outer ring of the support plate 71 to support the entire static mold 10. Then, the vibration motor 401 is started. Under the vibration action of the vibration motor 401, the powder in the powder box 4 can quickly enter the pressing groove 102 of the mold body 101. Then, several groups of static molds 10 are made to do circular motion again, and the above operation is repeated in a cycle. Until the mold body 101 loaded with powder moves to the right below the movable mold 6, the hydraulic cylinder 5 pushes the movable mold 6 downward, and the movable mold 6 drives the guide rod 32 to slide along the guide hole 31, guiding the movement of the movable mold 6, until the movable mold 6 enters the pressing groove 102 of the mold body 101, so that the powder in the pressing groove 102 is squeezed and shaped by the passive mold 6, and the ceramic product is pressed. Then the movable mold 6 is withdrawn, and several groups of static molds 10 are driven to make circular motions. The pressed ceramic product will move with the static mold 10. Until the roller 106 on the static mold 10 is squeezed by the protrusion 72, the roller 106 pushes the movable block 103 to move along the pressing groove 102 toward the conveyor belt mechanism 11, and at the same time the movable block 103 slides along the guide column 104, and the movable block 103 compresses the first spring 105, so that the ceramic product in the pressing groove 102 is pushed out by the movable block 103 and falls onto the conveyor belt mechanism 11 below, and the ceramic product is conveyed to the next process through the conveyor belt mechanism 11, so that the automatic unloading of the ceramic product is realized, until the roller 106 staggers the protrusion 72 , under the action of the rebound force of the first spring 105, the movable block 103 returns to the initial position, and then the above operation is repeated in a cycle. Compared with the prior art, as several groups of static molds 10 make circular motions, the powder in the powder box 4 can automatically enter the pressing groove 102 of the mold body 101, realizing automatic loading and improving the automation rate of the device. Secondly, the roller 106 is squeezed by the protrusion 72, so that the ceramic product in the pressing groove 102 is automatically ejected by the movable block 103, and the protrusion 72 replaces the power equipment to provide the unloading power, thereby reducing the equipment cost investment of the device.

[0026] like Figure 5 and Figure 6As shown, a dust removal mechanism 12 is provided between the first support frame 2 and the second support frame 3. The dust removal mechanism 12 includes a blanking box 121 fixedly installed on one side of the frame 1, a fixed seat 122 fixedly installed in the frame 1, a rotating shaft 123 rotatably connected to the fixed seat 122, six groups of scraping handles 124 equally angularly installed on the rotating shaft 123, a rubber scraping plate 125 installed on the scraping handle 124, a first bevel gear 126 installed at the lower end of the rotating shaft 123, a second bevel gear 127 meshing with the first bevel gear 126, one end of the driven shaft 128 connected to the second bevel gear 127, the other end of the driven shaft 128 connected to a driven sprocket 129, the driven sprocket 129 meshing with a group of chains 9, the driven shaft 128 rotatably installed on the frame 1, blanking plates 13 symmetrically arranged on both sides of the frame 1, a material receiving box 14 arranged on one side of a group of blanking plates 13, and the other group of blanking plates 13 being located above the blanking box 121.

[0027] Specifically, as several groups of static molds 10 make a circular motion, a small amount of powder will fall on the upper end face of the mold body 101. The powder will not only be separated from the powder box 4 along with the mold body 101, but also the powder will fall onto the conveyor belt mechanism 11 below along with the ceramic product, resulting in waste of the powder. Therefore, during the process of the chains 9 driving several groups of static molds 10 to make a circular motion, the chains 9 simultaneously drive the driven sprocket 129 to rotate. The driven sprocket 129 drives the driven shaft 128 together with the second bevel gear 127 to rotate. The second bevel gear 127 drives the rotating shaft 123 together with six groups of scraping handles 124 and six groups of rubber scraping plates 125 to rotate through the first bevel gear 126. The direction indicated by the arrow in the figure is the rotation direction. As the rubber scraping plate 125 rotates, the rubber scraping plate 125 will slide along the upper end face of the moving mold body 101, so that the powder on the upper end face of the mold body 101 is scraped off by the rubber scraping plate 125. Part of the powder will fall into the material receiving box 14 along a group of blanking plates 13, and the other part of the powder will be scraped by the rubber scraping plate 125 to the other group of blanking plates 13 and fall into the blanking box 121 along the other group of blanking plates 13, realizing the cleaning of the powder on the mold body 101 and achieving the purpose of saving resources. Figure 5 In the figure, the direction indicated by the arrow is the rotation direction. As the rubber scraping plate 125 rotates, the rubber scraping plate 125 will slide along the upper end face of the moving mold body 101, so that the powder on the upper end face of the mold body 101 is scraped off by the rubber scraping plate 125. Part of the powder will fall into the material receiving box 14 along a group of blanking plates 13, and the other part of the powder will be scraped by the rubber scraping plate 125 to the other group of blanking plates 13 and fall into the blanking box 121 along the other group of blanking plates 13, realizing the cleaning of the powder on the mold body 101 and achieving the purpose of saving resources.

[0028] Embodiment 2: As Figures 7 to 9As shown, compared with the first comparative example, another implementation of the present invention is as follows: The scraping handle 124 includes a fixed tube 1241. One end of the fixed tube 1241 is fixedly connected to the upper shaft sleeve 312 of the rotating shaft 123. A handle rod 1242 is movably inserted into the fixed tube 1241. A rubber scraper 125 is fixedly installed on the handle rod 1242. A rotary sleeve 1243 is rotatably installed on the handle rod 1242. A second spring 1244 is sleeved on the fixed tube 1241. One end of the second spring 1244 is fixedly connected to the end of the handle rod 1242, and the other end of the second spring 1244 is fixedly connected to the upper end of the rotating shaft 123. Two groups of slide rods 1245 are symmetrically distributed on both sides of the rotary sleeve 1243. The slide rods 1245 are slidably connected to the rotary sleeve 1243. One end of the slide rod 1245 is fixedly connected to the upper end of the rotating shaft 123. The rotary sleeve 1243 is fixedly connected to a connecting shaft 311. The lower end of the connecting shaft 311 is rotatably installed with a shaft sleeve 312. A guiding ring 1221 is fixedly sleeved on the upper end of the fixed seat 122. The outer ring of the shaft sleeve 312 is in rolling connection with the outer ring of the guiding ring 1221. The outer ring of the guiding ring 1221 is composed of a first ring surface 21, a second ring surface 22, several groups of grooves 23, and an inclined surface 24. Two groups of guiding grooves 411 are opened on the fixed tube 1241. Two groups of pin shafts 211 are symmetrically arranged on the end of the handle rod 1242. The pin shafts 211 are located in the guiding grooves 411. The guiding grooves 411 are composed of a spiral groove 41 and a straight groove 42. A number of brushes 1211 for cleaning the rubber scraper 125 are equiangularly arranged on the blanking box 121.

[0029] Specifically, when the rubber scraper 125 scrapes off the powder on the mold body 101, a small amount of powder will adhere to the rubber scraper 125. Since the powder contains chemical substances, the chemical substances react chemically with the rubber scraper 125. If the powder adheres to the rubber scraper 125 for a long time, the powder will accelerate the aging of the rubber scraper 125, thereby reducing the service life of the rubber scraper 125. Therefore, when the rubber scraper 125 scrapes off the powder on the mold body 101, the rubber scraper 125 is perpendicular to the mold body 101, and the shaft sleeve 312 on the handle 1242 moves along the first ring surface 2 on the guide ring 1221. 1 rolling, the second spring 1244 is in a stretched state. When the rubber scraper 125 is offset from the mold body 101, the sleeve 312 rolls from the first ring surface 21 to the second ring surface 22. Since the radius of the second ring surface 22 is smaller than the radius of the first ring surface 21, under the rebound force of the second spring 1244, the second spring 1244 will pull the handle 1242 to slide along the fixed tube 1241. At the same time, the handle 1242 drives the pin 211 to slide along the spiral groove 41. Under the guidance of the spiral groove 41, the handle 1242 and the rubber scraper 125 are rotated 90 degrees, so that the rubber scraper 125 is parallel to the upper end of the mold body 101. At this time, the pin 211 is located at the intersection of the spiral groove 41 and the linear groove 42. As the sleeve 312 slides along the second annular surface 22, the rubber scraper 125 will rub against the brush 1211, so that the brush 1211 will clean off the powder attached to the rubber scraper 125. Since a plurality of groups of grooves 23 are distributed on the second annular surface 22, when the sleeve 312 enters the groove 23, the handle 1242 will continue to slide along the fixed tube 1241 toward the rotating shaft 123, and the pin 211 will slide along the linear groove 42. When the sleeve 312 staggers the groove 23, the handle 1242 will continue to slide along the fixed tube 1241 away from the rotating shaft 123 slides, causing the pin 211 to return to the intersection of the spiral groove 41 and the linear groove 42. Since there are multiple groups of grooves 23 distributed on the second annular surface 22, the rubber scraper 125 moves back and forth along the axial direction of the handle rod 1242, thereby increasing the friction between the rubber scraper 125 and the brush 1211, so that the powder on the rubber scraper 125 is cleaned more cleanly by the brush 1211, thereby achieving the cleaning of the rubber scraper 125 and improving the service life of the rubber scraper 125, until the sleeve 312 rolls to the inclined surface 24, and the sleeve 312 is pushed by the inclined surface 24, so that the rubber scraper 125 is perpendicular to the mold body 101 again.

[0030] Working principle: A group of transmission shafts 7 are driven by a motor to rotate. The transmission shafts 7 drive two groups of driving sprockets 8 to rotate. The two groups of driving sprockets 8 drive two groups of chains 9 together with several groups of static molds 10 to perform circular motion, so that the mold body 101 is staggered from the lower end of the powder box 4, and at the same time the next group of mold bodies 101 is facing the lower end of the powder box 4. Then the vibration motor 401 is started. Under the vibration of the vibration motor 401, the powder in the powder box 4 can quickly enter the pressing groove 102 of the mold body 101. Then, the several groups of static molds 10 are made to perform circular motion again, and the above operations are repeated cyclically until the mold body 101 carrying the powder moves to directly below the moving mold 6. At this time, the moving mold 6 is pushed downward by the hydraulic cylinder 5 until the moving mold 6 enters the pressing groove 102 of the mold body 101, so that the powder in the pressing groove 102 is extruded and shaped by the moving mold 6, realizing the pressing of the ceramic product. Then the moving mold 6 is withdrawn, and the several groups of static molds 10 are continuously driven to perform circular motion. The formed ceramic product will move along with the static mold 10 until the roller 106 on the static mold 10 is squeezed by the convex block 72, causing the roller 106 to push the movable block 103 to move along the pressing groove 102 towards the conveyor belt mechanism 11. At the same time, the movable block 103 slides along the guide post 104, and the movable block 103 compresses the first spring 105, so that the ceramic product in the pressing groove 102 is pushed out by the movable block 103 and falls onto the conveyor belt mechanism 11 below. The conveyor belt mechanism 11 conveys the ceramic product to the next process, realizing the automatic blanking of the ceramic product. Until the roller 106 is staggered from the convex block 72, under the action of the rebounding force of the first spring 105, the movable block 103 returns to the initial position, and then the above operations are repeated cyclically; During the process that the chain 9 drives several groups of static molds 10 to perform circular motion, the chain 9 simultaneously drives the driven sprocket 129 to rotate. The driven sprocket 129 drives the driven shaft 128 together with the second bevel gear 127 to rotate. The second bevel gear 127 drives the rotating shaft 123 together with six scraping handles 124 and six rubber scraping plates 125 to rotate by means of the first bevel gear 126. Attached Figure 5 The direction indicated by the arrow in the figure is the rotation direction. As the rubber scraping plate 125 rotates, the rubber scraping plate 125 will slide along the upper end surface of the moving mold body 101, so that the powder on the upper end surface of the mold body 101 is scraped off by the rubber scraping plate 125. A part of the powder will fall into the material receiving box 14 along a group of material pouring plates 13, and another part of the powder will be scraped by the rubber scraping plate 125 to another group of material pouring plates 13 and fall into the blanking box 121 along the other group of material pouring plates 13, realizing the cleaning of the powder on the mold body 101; When the rubber scraper 125 is scraping off the powder on the mold body 101, the rubber scraper 125 is perpendicular to the mold body 101, and the sleeve 312 on the handle 1242 rolls along the first ring surface 21 on the guide ring 1221. The second spring 1244 is in a stretched state. When the rubber scraper 125 is offset from the mold body 101, the sleeve 312 rolls from the first ring surface 21 to the second ring surface 22. Since the radius of the second ring surface 22 is smaller than the radius of the first ring surface 21, the second spring 1244 is in a stretched state. Under the action of the rebound force, the second spring 1244 will pull the handle 1242 to slide along the fixed tube 1241, and at the same time, the handle 1242 drives the pin 211 to slide along the spiral groove 41. Under the guidance of the spiral groove 41, the handle 1242 and the rubber scraper 125 are rotated 90 degrees, so that the rubber scraper 125 is parallel to the upper end surface of the mold body 101. At this time, the pin 211 is located at the intersection of the spiral groove 41 and the linear groove 42. As the sleeve 312 slides along the second annular surface 22, the rubber scraper 125 The brush 1211 will rub against the brush 1211, so that the brush 1211 will clean the powder attached to the rubber scraper 125. Since the plurality of grooves 23 are distributed on the second annular surface 22, when the sleeve 312 enters the groove 23, the handle 1242 will continue to slide along the fixed tube 1241 toward the rotating shaft 123, and the pin 211 will slide along the linear groove 42. When the sleeve 312 staggers the groove 23, the handle 1242 will continue to slide along the fixed tube 1241 away from the rotating shaft 123, so that the pin 211 1 returns to the intersection of the spiral groove 41 and the linear groove 42. Since the second annular surface 22 is provided with a plurality of grooves 23, the rubber scraper 125 moves back and forth along the axial direction of the handle 1242, thereby increasing the friction between the rubber scraper 125 and the brush 1211, so that the powder on the rubber scraper 125 is cleaned more cleanly by the brush 1211, until the shaft sleeve 312 rolls to the inclined surface 24, and the shaft sleeve 312 is pushed by the inclined surface 24, so that the rubber scraper 125 is perpendicular to the mold body 101 again.
