Technical Field

[0001] This invention relates to the field of pharmaceutical production, and in particular to equipment for compressing expanding materials and its application methods. Background Technology

[0002] With the rapid development of synthetic biology, microbial fermentation technology has become an important approach for preparing bio-cellulose materials. Bacterial cellulose produced by *Acetobacter xylinum* fermentation, as a high-moisture food ingredient, has been widely used in coconut jelly granules and food thickeners to improve food texture and mouthfeel. In recent years, researchers have begun to explore its use in developing novel food forms with special functions, such as capsules with rapid water absorption and swelling properties. Such products are currently unavailable in the market and have promising development prospects.

[0003] In the process of tableting using raw materials such as bacterial cellulose, traditional equipment often causes the base plate to deform during the compression process, resulting in the leakage of raw material powder from the gap between the base mold and the base plate before complete molding. This problem not only affects the integrity of the tablet molding and the accuracy of the dosage, but also reduces the yield and quality stability of the product. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an expansion material compression device and its application method. This addresses the problem in the above-mentioned technical solutions where, during the tableting process using raw materials such as bacterial cellulose, traditional equipment often causes the base plate to deform under pressure, resulting in the leakage of raw material powder from the gap between the mold and the base plate before complete molding. An expansion material compression device includes a base, and a support structure is provided on one side of the base; A material feeding structure is provided above the base; The base is equipped with a material discharge structure inside; A loading structure is provided on one side of the base; The support structure includes a lower mold fixedly connected to the top of a base.

A push rod is slidably connected to the top of the extension plate. The end of the push rod near the column is sleeved on the outside of the column. A first support plate is fixedly connected to the end of the push rod away from the column. A first rack is fixedly connected to the outer wall of the push rod. A second gear is rotatably connected to the outer wall of the limit rod. The outer wall of the second gear meshes with the outer wall of the first rack. A second rack is slidably connected to the outer wall of the lower mold. A second support plate is fixedly connected to the end of the second rack away from the second gear. The outer wall of the second rack meshes with the outer wall of the second gear.

[0005] In a preferred embodiment, a connecting rod is fixedly connected to the side of the upper mold near the extension plate, a toothed plate is fixedly connected to the bottom of the connecting rod, a fixing block is fixedly connected to the bottom of the extension plate, a first gear is rotatably connected to the inner side wall of the fixing block, a first bevel gear is fixedly connected to one end of the first gear, and the outer side wall of the second bevel gear meshes with the outer side wall of the first bevel gear.

[0006] The beneficial effect of adopting the above-mentioned further solution is that by setting the toothed plate, the first gear, and the first bevel gear, it is easier to drive the rotating disk. In a preferred embodiment, the top of the extension plate is provided with a guide groove, and the bottom of the push rod is fixedly connected with a protrusion. The protrusion is located inside the guide groove, and the outer side wall of the protrusion fits into the inner side wall of the guide groove.

[0007] The beneficial effect of adopting the above-mentioned further solution is that by setting protrusions and guide grooves, it is easy to restrict the movement direction of the push rod and avoid the push rod from deviating in angle during movement.

[0008] In a preferred embodiment, a sliding rod is fixedly connected to the inner side wall of the base, the outer side wall of the sliding rod is slidably connected to the bottom of the first support plate, a clamp is slidably connected to the outer side wall of the sliding rod, and the top of the clamp is fixedly connected to the bottom of the second support plate.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting sliding rods and clamps, it is convenient to restrict the first support plate and the second support plate.

[0010] In a preferred embodiment, a limiting block is fixedly connected to the top of the base, and the base is slidably connected to the first rack through the limiting block. A fixing column is fixedly connected to the outer side wall of the lower mold, and the outer side wall of the fixing column is slidably connected to the inner side wall of the second rack. A discharge port is provided on the inner side wall of the base, and the bottom of the discharge port is set in an inclined shape. The discharge port is located below the lower mold.

[0011] The beneficial effects of adopting the above-mentioned further solution are: by setting fixed columns and limiting blocks, it is convenient to limit the angle of the second rack and the first rack, and avoid the first rack and the second rack from shifting their angles during movement. The discharge port and the bottom of the discharge port are set in an inclined shape, which facilitates the discharge of the tablets and reduces the chance of the tablets being stuck on the top of the base.

[0012] In a preferred embodiment, the feeding structure includes an arc-shaped groove extending through the top of the upper mold, a movable plate slidably connected to the outer side wall of the upper mold, a return spring fixedly connected to the top of the movable plate, the end of the return spring away from the movable plate being fixedly connected to the top of the upper mold, and an abutment rod fixedly connected to the bottom of the movable plate.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a movable plate and abutment rod, it is convenient to discharge the drug tablets retained inside the lower mold, thus avoiding the drug tablets remaining inside the lower mold.

[0014] In a preferred embodiment, a telescopic rod is fixedly connected to the bottom of the movable plate, the telescopic end of the telescopic rod is fixedly connected to the top of the upper mold, and an offset groove is provided on the top of the lower mold. The end of the abutment rod away from the movable plate is engaged with the offset groove.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting the telescopic rod and the deflection groove, the deflection groove facilitates the guidance of the abutment rod, so that the end of the abutment rod away from the moving plate deforms, making it easier for the abutment rod to enter the agent hole.

[0016] In a preferred embodiment, the discharge structure includes an installation groove formed in the inner side wall of the base, a round rod fixedly connected to the inner side wall of the base, the round rod being located inside the installation groove, a scraper slidably connected to the outer side wall of the round rod, a spring fixedly connected to the outer side wall of the scraper, the end of the spring away from the round rod being fixedly connected to the inner side wall of the base, and a pull plate fixedly connected to the outer side wall of the scraper.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting the mounting groove, round rod, scraper, spring, and pull plate, it is convenient to clean the medicine tablets at the top of the base and avoid the medicine tablets remaining inside the base.

[0018] In a preferred embodiment, the loading structure includes a square rod fixedly connected to the outer wall of the upper mold, a top plate slidably connected to the upper mold via the square rod, a groove extending through the outer wall of the top plate, a feed inlet extending through the top of the top plate, and a baffle fixedly connected to one side of the top plate.

[0019] The beneficial effects of adopting the above-mentioned further solution are: by setting up square rods, top plates, chutes, feed inlets, and baffles, it is convenient to fill the drug powder and avoid the drug powder from spilling during the filling process.

[0020] The application method of the expansion material compression equipment includes the following steps: S1: First, insert the base plate into the interior of the lower mold along the bottom of the lower mold, so that the top of the base plate fits against the bottom of the lower mold. Then, push the baffle along the square rod towards the lower mold, so that one side of the outer wall of the baffle fits against the outer wall of the lower mold. At this time, the feed port is aligned with the medicine discharge hole set on the top of the lower mold. Then, the operator pours the medicine powder onto the top of the top plate and fills the medicine powder evenly into the medicine discharge hole through several feed ports. Then, slide the top plate away from the lower mold to separate the top plate from the lower mold.

[0021] S2: Further, the cylinder at the top of the upper mold is activated. Under the action of the cylinder, the upper mold moves towards the lower mold. The extrusion rod at the bottom of the upper mold extrudes the powder inside the dispensing hole, causing the powder to become a tablet under high pressure. Simultaneously, as the upper mold moves towards the lower mold, the upper mold drives the toothed plate to move synchronously via a connecting rod. When the toothed plate moves downward, it drives the first gear to rotate synchronously, further driving the first bevel gear to rotate synchronously. At this time, the first bevel gear drives the second bevel gear, which meshes with it, to rotate. When the second bevel gear rotates, it drives the rotating disk to rotate. The column then rotates synchronously with the rotating disk because one end of the push rod is sleeved on the column. Externally, the push rod is slidably connected to the extension plate via a protrusion and guide groove. Therefore, when the rotating disk rotates, it will drive the push rod to move linearly. When the push rod moves linearly, it will drive the first rack to move synchronously. The first rack and the second rack are respectively meshed with the second gear, and the first rack and the second rack are distributed on both sides of the second gear. Therefore, the first rack and the second rack move in opposite directions. When the first rack moves synchronously with the push rod, it will drive the second rack to move in the opposite direction. In turn, the second rack will drive the second support plate to move, so that the first support plate and the second support plate gradually approach each other as the upper mold moves towards the lower mold, and support the bottom plate.

[0022] S3: After the drug powder is extruded, the upper mold moves away from the lower mold under the action of the cylinder. At this time, the operator can press the moving plate towards the lower mold. The abutment rod set at the bottom of the moving plate enters the drug hole set at the top of the lower mold under the guidance of the deflection groove. When the operator presses the moving plate further, the abutment rod squeezes the drug tablet stuck in the drug hole, causing the drug tablet to fall off from the bottom of the lower mold and fall into the discharge port.

[0023] S4: Because the bottom of the discharge port is sloped, after the tablets fall into the discharge port, they slide down the slope to the outside of the base. At this time, the operator can pull the pull plate away from the inside of the base. As the pull plate moves, it drives the scraper to scrape the inside of the discharge port, thereby cleaning the tablets stuck inside the discharge port and preventing tablets from remaining. In summary, the combined use of the upper mold, extension plate, rotating disk, second bevel gear, column, push rod, first rack, second rack, first support plate, and second support plate facilitates support of the bottom of the base plate, preventing excessive deformation of the base plate during the extrusion molding of the drug powder, thereby preventing leakage of the drug powder before it is formed and improving the forming rate of the drug powder.

[0024] The use of the arc groove, return spring, moving plate, contact rod, telescopic rod, and deflection groove facilitates the expulsion of the drug tablets retained inside the lower mold, preventing the drug tablets from remaining inside the lower mold and thus avoiding the impact of retained drug tablets on subsequent drug production.

[0025] The combination of square rods, top plate, chute, feed port, and baffle facilitates the filling of pharmaceutical powder and prevents spillage during the filling process, thus avoiding waste of pharmaceutical powder. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the present invention provides a technical solution: an expansion material compression device, including a base 1, and a support structure 2 is provided on one side of the base 1; A feeding structure 3 is provided above the base 1; The base 1 has a material discharge structure 4 inside; A loading structure 5 is provided on one side of the base 1; The support structure 2 includes a lower mold 201 fixedly connected to the top of the base 1.

A base plate 203 is slidably connected to the bottom of the lower mold 201. A handle is provided on the outer wall of the base plate 203 to facilitate the operator to pull out and insert the base plate 203. The top of the base plate 203 fits against the bottom of the lower mold 201. An extension plate 207 is fixedly connected to one side of the base 1. A connecting rod 205 is fixedly connected to the side of the upper mold 204 near the extension plate 207. A toothed plate 206 is fixedly connected to the bottom of the connecting rod 205. One outer wall of the toothed plate 206 is slidably connected to the inner wall of the extension plate 207. The bottom of the extension plate 207... A fixing block 208 is fixedly connected, and a first gear 209 is rotatably connected to the inner wall of the fixing block 208. A first bevel gear 210 is fixedly connected to one end of the first gear 209. The first gear 209 and the first bevel gear 210 are located on opposite sides of the fixing block 208. A rotating disk 211 is rotatably connected to the top of the extension plate 207. A second bevel gear 226 is fixedly connected to the bottom of the rotating disk 211. The outer wall of the second bevel gear 226 meshes with the outer wall of the first bevel gear 210. A column 212 is fixedly connected to the top of the rotating disk 211. A push rod 213 is slidably connected to the top of the extension plate 207. A rectangular slot with curved ends is provided on the side of the push rod 213 near the column 212. One end of the push rod 213 near the column 212 is fitted onto the outside of the column 212. The column 212 is located inside the rectangle with curved grooves at both ends. The end of the push rod 213 away from the column 212 is fixedly connected to the first support plate 217. The end of the first support plate 217 away from the push rod 213 is provided with a locking block. The first support plate 217 is located below the lower mold 201 and below the base plate 203. The top of the first support plate 217 is in contact with the bottom of the base plate 203. The inner side wall of the base 1 is fixedly connected to the slide rod 216. The outer side wall of the slide rod 216 is slidably connected to the bottom of the first support plate 217. The outer side wall of the slide rod 216 is slidably connected to the clamp 218. The top of the clamp 218 is fixedly connected to the second support. Plate 219, the second support plate 219 is provided with a groove on the side near the first support plate 217, the locking block provided on the outer wall of the first support plate 217 fits into the groove so that the first support plate 217 and the second support plate 219 can be engaged, the outer wall of the push rod 213 is fixedly connected to the first rack 220, the outer wall of the limiting rod 202 is rotatably connected to the second gear 221, the outer wall of the second gear 221 meshes with the outer wall of the first rack 220, the outer wall of the lower mold 201 is slidably connected to the second rack 222, the outer wall of the second rack 222 meshes with the outer wall of the second gear 221, and the end of the second rack 222 away from the second gear 221 is fixedly connected to the outer wall of the second support plate 219; In use, as the upper mold 204 moves towards the lower mold 201, the upper mold 204 drives the gear plate 206 to move synchronously via the connecting rod 205. When the gear plate 206 moves downward, it drives the first gear 209 to rotate synchronously, which in turn drives the first bevel gear 210 to rotate synchronously. At this time, the first bevel gear 210 drives the second bevel gear 226, which meshes with it, to rotate. When the second bevel gear 226 rotates, it drives the rotating disk 211 to rotate. At this time, the column 212 follows the rotating disk 211. 11. Synchronous rotation: Because one end of the push rod 213 is sleeved on the outside of the column 212, and the push rod 213 is slidably connected to the extension plate 207 through the protrusion 214 and guide groove 215, when the rotating disk 211 rotates, it will drive the push rod 213 to move linearly. When the push rod 213 moves linearly, it will drive the first rack 220 to move synchronously. The first rack 220 and the second rack 222 respectively mesh with the second gear 221, and the first rack 220 and the second rack 222 are distributed... Located on both sides of the second gear 221, the first rack 220 and the second rack 222 move in opposite directions. When the first rack 220 moves synchronously with the push rod 213, it will drive the second rack 222 to move in the opposite direction. Since the second rack 222 is fixedly connected to the outer wall of the second support plate 219, the movement of the second rack 222 will drive the second support plate 219 to move, thereby causing the first support plate 217 and the second support plate 219 to move from the upper mold 204 to the lower mold 201. As the cylinder gradually approaches the upper mold 204, when the first support plate 217 and the second support plate 219 engage with each other, the cylinder's compression of the upper mold 204 reaches its maximum. At this time, the first support plate 217 and the second support plate 219 support the bottom plate 203, preventing the bottom plate 203 from deforming when compressed by the drug powder. This prevents the drug powder from leaking through the gap between the bottom plate 203 and the lower mold 201 during the compression process, thus preventing changes in the dosage of the drug tablet and improving the quality of the drug tablet.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the top of the extension plate 207 is provided with a guide groove 215. There are two guide grooves 215, which are located on both sides of the rotating disk 211. The bottom of the push rod 213 is fixedly connected with a protrusion 214. There are two protrusions 214, which are located inside the two guide grooves 215. The outer side wall of the protrusion 214 fits into the inner side wall of the guide groove 215. When the push rod 213 moves linearly following the rotation of the rotating disk 211, the two protrusions 214 and the two guide grooves 215 restrict the movement direction of the push rod 213 to prevent the push rod 213 from deviating in angle during the movement.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a limiting block 224 is fixedly connected to the top of the base 1. Two limiting blocks 224 are provided. The base 1 is slidably connected to the first rack 220 through the two limiting blocks 224. A fixing post 223 is fixedly connected to the outer wall of the lower mold 201. Two fixing posts 223 are provided. The outer walls of the two fixing posts 223 are slidably connected to the inner walls of the second rack 222 respectively. The two fixing posts 223 and the two limiting blocks 224 respectively limit the movement angle of the first rack 220 and the second rack 222 to prevent the first rack 220 and the second rack 222 from shifting their angles during movement, thereby preventing the first rack 220 and the second rack 222 from disengaging from the second gear 221 during movement.

[0032] like Figure 5 and Figure 8 As shown, a discharge port 225 is provided on the inner side wall of the base 1. The bottom of the discharge port 225 is set in an inclined shape. The discharge port 225 is located below the lower mold 201. Under the action of the discharge port 225, the inner top of the base 1 forms an inclined slope. When the formed medicine tablet falls into the interior of the discharge port 225, it slides along the inner top of the base 1 until it is discharged from the interior of the base 1, which is convenient for the operator to collect.

[0033] like Figure 1 , Figure 6 and Figure 7 As shown, the feeding structure 3 includes an arc-shaped groove 301 that runs through the top of the upper mold 204. Multiple arc-shaped grooves 301 are provided, and the positions of the multiple arc-shaped grooves 301 correspond to the positions of the extrusion rods provided at the bottom of the upper mold 204. A movable plate 303 is slidably connected to the outer wall of the upper mold 204. The movable plate 303 is located above the upper mold 204. A return spring 302 is fixedly connected to the top of the movable plate 303. Four return springs 302 are provided, and the positions of the four return springs 302 correspond to the positions of the four limit rods 202. The end of the return spring 302 away from the movable plate 303 is fixedly connected to the top of the upper mold 204. An abutment rod 304 is fixedly connected to the bottom of the movable plate 303. The abutment rod 304 covers the arc-shaped groove 301 and covers the outside of the extrusion rod. The abutment rod 304 is made of acrylic sheet and can be tilted to a certain extent so as to enter the agent hole opened at the top of the lower mold 201. After the drug is extruded and molded, the operator can use the handle provided on the outside of the base plate 203 to pull it out from the bottom of the base plate 203. Furthermore, the operator can press the moving plate 303 towards the lower mold 201. The abutment rod 304 provided at the bottom of the moving plate 303 enters the drug hole provided at the top of the lower mold 201 under the guidance of the deflection groove 306. When the operator presses the moving plate 303 further, the abutment rod 304 squeezes the drug tablet stuck in the drug hole, causing the drug tablet to fall off from the bottom of the lower mold 201 and fall into the discharge port 225.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, a telescopic rod 305 is fixedly connected to the bottom of the movable plate 303. The telescopic end of the telescopic rod 305 is fixedly connected to the top of the upper mold 204. A deflection groove 306 is provided on the top of the lower mold 201. An arc is provided at the junction of the deflection groove 306 and the top of the lower mold 201. The end of the abutment rod 304 away from the movable plate 303 is engaged with the deflection groove 306. When the abutment rod 304 is squeezed and moves towards the lower mold 201, the end of the abutment rod 304 near the deflection groove 306 is deformed by pressure. At the same time, an arc is provided at the junction of the deflection groove 306 and the lower mold 201. At this time, the end of the deflection groove 306 near the lower mold 201 enters the drug hole opened on the top of the lower mold 201 along the deflection groove 306, and squeezes the extruded and retained drug tablet in the drug hole, so that the drug tablet separates from the inner wall of the lower mold 201, thereby preventing the drug tablet from being retained inside the lower mold 201.

[0035] like Figure 5 , Figure 8 As shown, the discharge structure 4 includes two mounting grooves 401 formed on the inner wall of the base 1. The two mounting grooves 401 are located on the inner walls of both sides of the base 1. Two round rods 402 are fixedly connected to the inner wall of the base 1, and are located inside the two mounting grooves 401 respectively. Two scrapers 403 are slidably connected to the outer wall of the round rods 402, and are respectively sleeved on the outside of the two round rods 402. A spring 404 is fixedly connected to the side wall. The bottom of the spring 404 is in contact with the inner top of the base 1. The end of the spring 404 away from the round rod 402 is fixedly connected to the inner side wall of the base 1. A pull plate 405 is fixedly connected to the outer side wall of the scraper 403. In use, the pull plate 405 is pulled away from the inside of the base 1. During the movement, the pull plate 405 drives the scraper 403 to scrape the inside of the discharge port 225, thereby cleaning the tablets stuck inside the discharge port 225 and preventing the tablets from being stuck.

[0036] like Figure 1 and Figure 9 As shown, the loading structure 5 includes a square rod 501 fixedly connected to the outer wall of the upper mold 204. The upper mold 204 is slidably connected to a top plate 502 via the square rod 501. A groove 503 is provided through the outer wall of the top plate 502. A feed port 504 is provided through the top of the top plate 502. A baffle 505 is fixedly connected to one side of the top plate 502. In use, the baffle 505 is pushed along the square rod 501 toward the lower mold 201, so that one side of the outer wall of the baffle 505 is in contact with the outer wall of the lower mold 201. At this time, the feed port 504 is aligned with the medicine discharge hole set at the top of the lower mold 201. The operator then pours the medicine powder onto the top of the top plate 502 and fills the medicine powder evenly into the medicine discharge hole through the feed ports 504, so as to avoid the medicine powder from spilling during filling and to avoid waste of medicine powder.

[0037] The application method of the expansion material compression equipment includes the following steps: S1: First, insert the base plate 203 into the interior of the lower mold 201 along the bottom of the lower mold 201, so that the top of the base plate 203 fits against the bottom of the lower mold 201. Then, push the baffle 505 along the square rod 501 toward the lower mold 201, so that one side of the outer wall of the baffle 505 fits against the outer wall of the lower mold 201. At this time, the feed port 504 is aligned with the medicine discharge hole set on the top of the lower mold 201. Then, the operator pours the medicine powder onto the top of the top plate 502 and fills the medicine powder evenly into the medicine discharge hole through several feed ports 504. Then, slide the top plate 502 away from the lower mold 201, so that the top plate 502 is separated from the lower mold 201.

[0038] S2: Further, the cylinder at the top of the upper mold 204 is activated. Under the action of the cylinder, the upper mold 204 moves towards the lower mold 201. The extrusion rod at the bottom of the upper mold 204 extrudes the powder inside the dispensing hole, causing the powder to become a tablet under high pressure. While the upper mold 204 moves towards the lower mold 201, the upper mold 204 drives the toothed plate 206 to move synchronously via the connecting rod 205. When the toothed plate 206 moves downward, it drives the first gear 209 to rotate synchronously, further driving the first bevel gear 210 to rotate synchronously. At this time, the first bevel gear 210 drives the second bevel gear 226, which meshes with it, to rotate. When the second bevel gear 226 rotates, it drives the rotating disk 211 to rotate. At this time, the column 212 rotates synchronously with the rotating disk 211. Because one end of the push rod 213 is sleeved on the outside of the column 212, and the push rod 21 3. The extension plate 207 is slidably connected to the protrusion 214 and guide groove 215. Therefore, when the rotating disk 211 rotates, it will drive the push rod 213 to move linearly. When the push rod 213 moves linearly, it will drive the first rack 220 to move synchronously. The first rack 220 and the second rack 222 are respectively meshed with the second gear 221. The first rack 220 and the second rack 222 are distributed on both sides of the second gear 221. Therefore, the first rack 220 and the second rack 222 move in opposite directions. When the first rack 220 moves synchronously with the push rod 213, it will drive the second rack 222 to move in the opposite direction. Then, the second rack 222 will drive the second support plate 219 to move. As the upper mold 204 moves towards the lower mold 201, the first support plate 217 and the second support plate 219 gradually approach each other and support the bottom plate 203.

[0039] S3: After the drug powder is extruded, the upper mold 204 moves away from the lower mold 201 under the action of the cylinder. At this time, the operator can press the moving plate 303 towards the lower mold 201. The abutment rod 304 set at the bottom of the moving plate 303 enters the drug hole set at the top of the lower mold 201 under the guidance of the deflection groove 306. When the operator presses the moving plate 303 further, the abutment rod 304 squeezes the drug tablet stuck in the drug hole, causing the drug tablet to fall off from the bottom of the lower mold 201 and fall into the discharge port 225.

[0040] S4: Since the bottom of the discharge port 225 is set to be inclined, after the tablets fall into the discharge port 225, they slide down the bottom of the discharge port 225 to the outside of the base 1. At this time, the operator can pull the pull plate 405 away from the inside of the base 1. During the movement, the pull plate 405 drives the scraper 403 to scrape the inside of the discharge port 225, thereby cleaning the tablets stuck inside the discharge port 225 and preventing the tablets from being stuck.
