Description

Technical Field

[0001] The present application relates to the technical field of pressure-sensitive green ceramic film processing, and in particular to a device for recycling waste edge materials of pressure-sensitive green ceramic film strips. Background Art

[0002] Tape casting is a key process for manufacturing chip varistors. It enables rapid and inexpensive production of large-area varistor green ceramic films with high production efficiency, consistent product quality, stable performance, and ease of continuous and automated production. Tape casting technology is applicable to ceramic substrates, LTCC, MTCC, and HTCC. Applications include high-thermal conductivity heat dissipation substrates such as aluminum nitride and silicon nitride, electronic packaging for HTCC multilayer interconnect devices such as aluminum nitride and aluminum oxide, and the molding and preparation of YAG multilayer composite ceramic lasers, ZnO varistors, and porous SiC ceramics.

[0003] Although tape casting technology is applied in various fields, the green films after tape casting inevitably undergo processing operations such as trimming. At the same time, the cast green films with defects such as pinholes and craters need to be discarded, resulting in great waste. At the same time, cast films often contain a large amount of organic matter, such as macromolecular binders such as polyvinyl butyral, which are not easy to degrade. Directly discarding the cast films causes environmental pollution. In addition, certain alkali metal / alkaline earth metal oxides and rare earth oxides are added to ceramic slurries using liquid phase sintering. Directly discarding them also causes environmental pollution and increases the cost of material preparation. Summary of the Invention

[0004] In order to overcome the problems existing in the prior art, the present application provides a device for recycling waste edge materials of pressure-sensitive raw ceramic membrane strips.

[0005] The present application provides a pressure-sensitive ceramic film tape waste recycling device that adopts the following technical solutions:

[0006] A pressure-sensitive raw ceramic film strip waste material recycling equipment, including a reeling and unreeling mechanism, including a reeling roller and a reeling roller, a PET film with a pressure-sensitive raw ceramic film wound on the reeling roller, and a plurality of guide rollers are provided between the reeling roller and the reeling roller, a waste edge scraping mechanism and a tensioning mechanism are installed between the guide rollers; the waste edge scraping mechanism includes a scraper and a bracket for installing the scraper, wherein the bottom of the scraper is also provided with a material receiving box, the two ends of the top of the bracket are rotatably connected to the frame, the end of the bracket away from the scraper is connected to the bracket through a tensioning spring, and the bracket rotates under the action of the tensioning spring and drives the scraper to fit the PET surface; the tensioning mechanism includes an upper roller body located above the PET and a lower roller body below the PET, the upper roller body and the lower roller body are staggered, wherein the upper roller body is installed on the tensioning seat, and the lower roller body is installed on the rotating frame, the rotating frame is movably installed on both sides of the bracket, and the lower roller body and the scraping side of the scraper are correspondingly distributed on the upper and lower sides of the PET film.

[0007] By adopting the above technical solution, the PET film with pressure-sensitive raw ceramic film is unwound from the unwinding roller, and after being guided by several guide rollers, enters the area where the waste edge scraping mechanism and the tensioning mechanism are located. During this process, the upper roller and the lower roller of the tensioning mechanism are staggered, and the scraping side of the lower roller and the scraper are located on the upper and lower sides of the PET film respectively. The upper roller is installed on the tensioning seat and the lower roller is installed on the movable rotating frame. A tensioning force is formed on the PET film to keep it flat; at the same time, the two ends of the bracket of the waste edge scraping mechanism are rotatably connected to the frame, and the scraping side is remote. The end away from the scraper is pulled by a tensioning spring, allowing the scraper to closely adhere to the surface of the PET film under the action of the tensioning spring. Furthermore, because the lower roller corresponds to the scraping side of the scraper, when the staggered upper and lower rollers tension the PET film, the lower roller inevitably lifts a portion of the PET film upward, forming an upwardly convex arc structure at the contact point between the PET film and the scraper. This arc structure can better separate the pressure-sensitive raw ceramic film from the PET film, and cooperates with the scraper to effectively scrape off the waste edge of the pressure-sensitive raw ceramic film, which falls into the bottom receiving box. The treated PET film continues to be guided by the guide roller and finally wound up by the winder, thus realizing the automated scraping and recycling of the waste edge of the pressure-sensitive raw ceramic film.

[0008] Preferably, the bracket is detachably mounted on the frame through a movable mounting sleeve, wherein the movable mounting sleeve includes an integrally formed connecting portion and a connecting sleeve inside the connecting portion, the connecting portion adopts a U-shaped structure, and the connecting portion is provided with an adjustment groove along its length direction, and a plurality of threaded grooves corresponding to the adjustment grooves are installed on the frame along the length direction of the connecting portion, wherein a locking rod mounted on the threaded groove fixes the connecting portion to the frame.

[0009] Preferably, the bracket includes a mounting plate and mounting shafts at both ends, wherein the mounting shaft is rotatably mounted in a connecting sleeve, a circumferential array of limiting protrusions is provided on the outer ring of the mounting shaft, and a guide groove adapted to the limiting protrusion is provided in the connecting sleeve, and the guide groove is used to limit the rotation angle of the bracket.

[0010] Preferably, both ends of the mounting plate are provided with rotation grooves rotatably connected to the mounting shaft, wherein a locking hole is provided at the top of the rotation groove, and a locking bolt passing through the locking hole is adapted to the locking groove on the mounting shaft.

[0011] By adopting the above technical solution, the movable mounting sleeve consists of an integrally formed U-shaped connecting portion and an inner connecting sleeve. The connecting portion has an adjustment slot along its length, corresponding to multiple threaded slots on the frame. The opening of the connecting portion of the movable mounting sleeve is inserted into the frame, aligning the adjustment slot with the threaded slot. The adjustment slot is a long strip. A locking rod is inserted into the threaded slot to secure the connecting portion to the frame, allowing the movable mounting sleeve to be installed at different positions on the frame. The mounting shafts at both ends of the bracket are rotatably mounted within the connecting sleeves. The stopper protrusions on the outer ring of the mounting shafts mate with the guide slots in the connecting sleeves, thereby limiting the bracket's rotation angle and preventing damage to the PET film caused by excessive rotation of the scraper. The mounting plate of the bracket has rotation slots at both ends, which are rotatably connected to the mounting shafts. The locking holes at the top of the rotation slots pass through the locking bolts that mate with the locking slots on the mounting shafts. When the mounting shafts become worn over time, the locking bolts can be removed to replace the mounting shafts. This structure enables the bracket to be removably mounted on the frame and its angle adjusted.

[0012] Preferably, a mounting groove is provided on the top surface of the mounting plate, and the scraper is clamped and installed in the mounting groove by a clamping plate, wherein mounting holes corresponding to the scraper are provided on the clamping plate and the mounting plate, and a material guide plate is integrally formed along the length direction of the clamping plate on the side away from the scraper, and a threaded hole is provided on the end of the clamping plate away from the scraper, and the positioning bolt passes through the back plate of the mounting plate and is connected to the threaded hole.

[0013] Preferably, a convex arc-shaped material guiding surface is provided on the side of the material guiding plate facing the scraper, and material guiding grooves corresponding to the edges of the material guiding plate are provided at both ends of the mounting plate.

[0014] Preferably, multiple groups of tension springs are provided and distributed parallel to each other, wherein the tension springs are respectively connected to the frame and the positioning bolts.

[0015] By adopting the above technical solution, the scraper is first placed in the mounting groove on the top surface of the mounting plate. The scraper is clamped using a clamping plate and positioned using corresponding mounting holes on the clamping plate and mounting plate. The positioning bolt is then threaded through the back plate of the mounting plate and into the threaded hole on the end of the clamping plate away from the scraper to secure the clamping plate and scraper. A guide plate integrally formed on the side of the clamping plate away from the scraper, with its curved guide surface facing the scraper, guides the flow of waste material. Guide grooves at both ends of the mounting plate correspond to the edges of the guide plate, further directing the waste material. Multiple sets of parallel tension springs are connected to the frame at one end and to the positioning bolts at the other. The elastic tension of the springs drives the clamping plate and scraper through the positioning bolts, ensuring that the scraper fits tightly against the surface of the PET film. This allows for scraping of the waste edges of the pressure-sensitive raw ceramic film during operation, while ensuring the stability and continuity of the scraping process.

[0016] Preferably, the tensioning seat includes a seat body and a tensioning part connected to the top frame on the back of the seat body, wherein the seat body adopts a horizontal U-shaped structure, the tensioning part includes a fixing rod vertically connected to the seat body, and a fixing sleeve is mounted on the top of the fixing rod, wherein a limit block is provided on the top of the fixing rod to limit the fixing rod within the fixing sleeve, and a spring is mounted on the fixing rod to connect the end of the fixing sleeve and the top of the seat body.

[0017] Preferably, the rotating frame adopts an L-shaped structure and is symmetrically installed on both sides of the mounting plate, one end of which is rotatably installed on the mounting shaft, and the other end is rotatably installed with the lower roller body. The top of one end of the rotating frame close to the lower roller body is connected to the side of the mounting plate through an adjustment mechanism.

[0018] Preferably, the adjustment mechanism includes an adjustment screw rotatably mounted on the top surface of the rotating frame, the adjustment screw passes through a threaded sleeve at the side end of the mounting plate, the adjustment screw passes through the threaded sleeve and an adjustment nut is mounted on the adjustment screw at the top of the threaded sleeve.

[0019] By adopting the above technical solution, the tensioning seat has a U-shaped base. The tensioning portion on its back is connected to the top frame via a fixed rod. A fixed sleeve is mounted on the top of the fixed rod. A limit block prevents the fixed rod from separating from the fixed sleeve. A spring is mounted on the fixed rod, connecting the end of the fixed sleeve to the top of the base, providing elastic tension. The turret is L-shaped and symmetrically arranged on either side of the mounting plate. One end is rotatably mounted on the mounting shaft, and the other end is mounted on the lower roller, providing rotational support for the lower roller. The top of the turret near one end of the lower roller is connected to the side of the mounting plate through an adjustment mechanism. The adjustment screw is rotatably mounted on the top surface of the turret and extends through a threaded sleeve at the side end of the mounting plate. The adjustment nut is mounted on the adjustment screw at the top of the threaded sleeve. Rotating the adjustment nut drives the adjustment screw up and down along the threaded sleeve, thereby adjusting the angle of the turret, changing the spacing and relative position between the lower and upper rollers, and precisely adjusting the tension on the PET film in conjunction with the elastic tensioning force of the tensioning seat.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

In addition, the scraper of the scraping mechanism, under the action of the tension spring, closely adheres to the PET surface, can effectively scrape off the waste edges of the pressure-sensitive raw ceramic film and collect them in the receiving box, thereby realizing efficient recycling of the waste edges and reducing waste.

[0022] 2. The bracket in this application can be detachably mounted on the rack via a movable mounting sleeve, which facilitates the installation, commissioning, and maintenance of the equipment. Furthermore, the position of the bracket can be adjusted via an adjustment slot and a locking rod, thereby improving the adaptability of the equipment.

[0023] 3.

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiment of the present application discloses a device for recycling waste edge materials of pressure-sensitive green ceramic film strips.

[0031] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4A device for recycling waste edge materials of pressure-sensitive raw ceramic film comprises a rewinding and unwinding mechanism 1, comprising a rewinding roller 11 and a rewinding roller 12, a PET film 13 with a pressure-sensitive raw ceramic film wound on the rewinding roller 11, and a plurality of guide rollers 14 are provided between the rewinding roller 11 and the rewinding roller 12, a waste edge scraping mechanism 2 and a tensioning mechanism 3 are installed between the guide rollers 14; the waste edge scraping mechanism 2 comprises a scraper 21 and a bracket 22 for mounting the scraper 21, wherein a material receiving box 23 is further provided at the bottom of the scraper 21, and the two ends of the top of the bracket 22 are rotatably connected to the frame 5, and the bracket 22 is away from the scraper 21. One end is connected to the bracket 22 through a tensioning spring 24, and the bracket 22 rotates under the action of the tensioning spring 24 and drives the scraper 21 to fit the PET surface; the tensioning mechanism 3 includes an upper roller 31 located above the PET and a lower roller 32 below the PET, and the upper roller 31 and the lower roller 32 are staggered, wherein the upper roller 31 is mounted on the tensioning seat 311, and the lower roller 32 is mounted on the rotating frame 321, and the rotating frame 321 is movably mounted on both sides of the bracket 22, and the lower roller 32 and the scraping side of the scraper 21 are correspondingly distributed on the upper and lower sides of the PET film 13. The PET film 13 with the pressure-sensitive raw ceramic film is unwound from the unwinding roller 11, and after being guided by a plurality of guide rollers 14, enters the area where the scraping mechanism 2 and the tensioning mechanism 3 are located. During this process, the upper roller 31 and the lower roller 32 of the tensioning mechanism 3 are staggered. The lower roller 32 and the scraping side of the scraper 21 are located on the upper and lower sides of the PET film 13 respectively. The upper roller 31 is installed on the tensioning seat 311 and the lower roller 32 is installed on the movable rotating frame 321. A tensioning force is formed on the PET film 13 to keep it flat. At the same time, the bracket 22 of the scraping mechanism 2 is rotatably connected to the frame 5 at both ends, away from the scraper 21. One end of the roller 32 is pulled by the tensioning spring 24, so that the scraper 21 is closely attached to the surface of the PET film 13 under the action of the tensioning spring 24. Moreover, since the lower roller 32 is arranged corresponding to the scraping side of the scraper 21, when the staggered upper and lower rollers 31 and 32 tension the PET film 13, the lower roller 32 will inevitably lift a portion of the PET film 13 upward, so that an upwardly convex arc structure is formed at the contact point between the PET film 13 and the scraper 21. This arc structure can better separate the pressure-sensitive raw ceramic film from the PET film 13, and cooperate with the scraper 21 to effectively scrape off the waste edge of the pressure-sensitive raw ceramic film, and the scraped waste edge falls into the bottom receiving box 23. The processed PET film 13 continues to be guided by the guide roller 14 and is finally wound up by the winding roller 12, thereby realizing the automatic scraping and recycling of the waste edge of the pressure-sensitive raw ceramic film.

[0032] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4The bracket 22 is detachably mounted on the frame 5 via a movable mounting sleeve 4. The movable mounting sleeve 4 includes an integrally formed connecting portion 41 and a connecting sleeve 42 located within the connecting portion 41. The connecting portion 41 has a U-shaped structure and is provided with an adjustment slot 411 along its length. The frame 5 is provided with a plurality of threaded grooves 51 corresponding to the adjustment slots 411 along the length of the connecting portion 41. Locking rods 52 mounted on the threaded grooves 51 secure the connecting portion 41 to the frame 5. The bracket 22 includes a mounting plate 221 and mounting shafts 222 at both ends. The mounting shafts 222 are rotatably mounted within the connecting sleeve 42. The outer ring of the mounting shaft 222 is provided with a circumferential array of limit protrusions 2221. The connecting sleeve 42 includes guide grooves 421 adapted to mate with the limit protrusions 2221. The guide grooves 421 are used to limit the rotation angle of the bracket 22. The mounting plate 221 has rotation slots at both ends that are rotatably connected to the mounting shaft 222. The top of the rotation slots has locking holes 2211, and locking bolts 2212 extending through the locking holes 2211 mate with the locking slots on the mounting shaft 222. The movable mounting sleeve 4 comprises an integrally formed U-shaped connecting portion 41 and an inner connecting sleeve 42. The connecting portion 41 has adjustment slots 411 along its length, and the frame 5 has a plurality of corresponding threaded slots 51. The opening of the connecting portion 41 of the movable mounting sleeve 4 is fitted onto the frame 5, aligning the adjustment slots 411 with the threaded slots 51. The adjustment slots 411 are elongated strips in structure. A locking rod 52 is fitted over the threaded slots 51 to secure the connecting portion 41 to the frame 5, allowing the movable mounting sleeve 4 to be installed at different positions on the frame 5. The mounting shafts 222 at both ends of the bracket 22 are rotatably mounted within the connecting sleeve 42. The limiting protrusions 2221 on the outer ring of the mounting shaft 222 mate with the guide grooves 421 within the connecting sleeve 42, thereby limiting the rotation angle of the bracket 22 and preventing the scraper 21 from rotating at an excessive angle and causing damage to the PET film 13. The mounting plate 221 of the bracket 22 has rotation grooves at both ends that are rotatably connected to the mounting shaft 222. The locking holes 2211 at the top of the rotation grooves pass through locking bolts 2212 that mate with the locking grooves on the mounting shaft 222. When the mounting shaft 222 becomes worn after prolonged use, the locking bolts 2212 can be removed to replace the mounting shaft 222. This structure allows the bracket 22 to be detachably mounted on the frame 5 and its angle adjusted.

[0033] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4The top surface of the mounting plate 221 defines a mounting slot 2213, within which the scraper 21 is clamped and mounted via a clamping plate 25. Both the clamping plate 25 and the mounting plate 221 are provided with mounting holes 26 corresponding to the scraper 21.

Multiple sets of tension springs 24 are provided, distributed parallel to each other, each connected to the frame 5 and the positioning bolts 252. First, place the scraper 21 in the mounting groove 2213 on the top surface of the mounting plate 221. Clamp the scraper 21 using the clamping plate 25, positioning it through the corresponding mounting holes 26 on the clamping plate 25 and the mounting plate 221. Then, screw the positioning bolts 252 through the back plate of the mounting plate 221 and into the threaded holes on the end of the clamping plate 25 facing away from the scraper 21, securing the clamping plate 25 and the scraper 21. The side of the clamping plate 25 facing away from the scraper 21 is integrally formed with a guide plate 251. Its curved guide surface facing the scraper 21 guides the flow of waste material. Guide grooves 2214 at both ends of the mounting plate 221 correspond to the edges of the guide plate 251, further guiding the waste material. Multiple groups of tension springs 24 are distributed in parallel with each other, one end of which is connected to the frame 5 and the other end is connected to the positioning bolt 252. The elastic tension of the spring 316 is used to drive the clamping plate 25 and the scraper 21 through the positioning bolt 252, so that the scraper 21 is closely attached to the surface of the PET film 13, and the waste edge of the pressure-sensitive raw ceramic film is scraped off during the operation of the PET film 13, while ensuring the stability and continuity of the scraping work.

The seat body 312 adopts a horizontal U-shaped structure. The tensioning portion 313 includes a fixing rod 314 connected vertically to the seat body 312. A fixing sleeve 315 is mounted on the top of the fixing rod 314. A limit block is provided on the top of the fixing rod 314 to confine the fixing rod 314 within the fixing sleeve 315. The fixing rod 314 is also mounted on a spring 316 that connects the end of the fixing sleeve 315 and the top of the seat body 312. The rotating frame 321 adopts an L-shaped structure and is symmetrically mounted on both sides of the mounting plate 221. One end is rotatably mounted on the mounting shaft 222, and the other end is rotatably mounted with the lower roller body 32. The top of the end of the rotating frame 321 near the lower roller body 32 is connected to the side of the mounting plate 221 via an adjustment mechanism 33. The adjustment mechanism 33 includes an adjustment screw 331 rotatably mounted on the top surface of the rotating frame 321.

A fixed sleeve 315 is mounted on the top of the fixed rod 314. A limit block prevents the fixed rod 314 from separating from the fixed sleeve 315. A spring 316 is mounted on the fixed rod 314, connecting the end of the fixed sleeve 315 to the top of the base 312 to provide elastic tension. When the adjusting screw 331 is in the state of being rotated by the guide rail 331 and the adjusting screw 332 is in the state of being rotated by the guide rail 332, the adjusting screw 331 can be rotated to move up and down along the guide rail 332 to adjust the angle of the adjusting screw 331.

[0035] Working Principle: PET film 13 with pressure-sensitive green ceramic film begins unwinding from unwinding roller 11 and is guided and transported by several sets of guide rollers 14. During this transport, the scrap edge scraping mechanism 2 begins to operate. Bracket 22 rotates under the action of tensioning spring 24, causing scraper 21 to tightly contact the surface of PET film 13, scraping off the waste edges of the pressure-sensitive green ceramic film. The scraped waste edges are then collected in a collection box 23 at the bottom of scraper 21. At the same time, the tensioning mechanism 3 is also playing a role. The upper roller 31 above the PET film 13 and the lower roller 32 below it are arranged alternately. The upper roller 31 is installed on the tensioning seat 311, and the lower roller 32 is installed on the rotating frame 321.
