Description

Technical Field

[0001] This utility model relates to the technical field of coating apparatus, and in particular to a coating die head. Background Technology

[0002] Currently, the production of cast film mainly involves using coating equipment to apply slurry onto a winding base strip to form a uniform thin layer of slurry. After drying in a hot air zone, a film is obtained. Existing coating equipment uses a die to apply slurry onto the base strip. The die has an outlet for slurry to flow out. If it is necessary to change the coating width on the base strip, the die needs to be removed and tape is applied inside to seal part of the outlet, thereby adjusting the size of the outlet.

[0003] However, existing coating equipment lacks positioning capabilities, making it impossible to quickly and accurately determine the length of the tape. Utility Model Content

[0004] The purpose of this invention is to provide a coating die head to solve the technical problem that existing coating dies are difficult to accurately control the coating width.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coating die head is provided, comprising: a die head body for connecting to a feeding system and having a rectangular longitudinal section, the die head body including a detachably connected first part and a second part, which are connected to form an inner cavity for storing slurry, the inner cavity extending to the top of the die head body and forming a slurry outlet on the surface of the top; at least one adjusting block for abutting against a coating roller, the at least one adjusting block being movably disposed on the top of the die head body along the length direction of the die head body, the adjusting block having an opposing liquid outlet end and a sealing end; and a tape extending from the sealing end of the adjusting block to the end of the die head body and sealing the slurry outlet located between the adjusting block and the end of the die head body.

[0006] In some embodiments, a groove is formed on the surface of the second part that abuts against the first part, the groove forming an inner cavity when the first part and the second part are connected, and the tape is adhered to the inner wall of the groove of the second part.

[0007] In some embodiments, there are two adjusting blocks, which are arranged alternately on the die head body, and an adhesive tape is provided between each adjusting block and the end of the die head body adjacent to the adjusting block.

[0008] In some embodiments, a groove is provided on the top of the die head body, the groove extends along the length direction of the die head body, an adjusting block is movably disposed in the groove, and the slurry outlet is located on the bottom surface of the groove.

[0009] In some embodiments, a pressure plate is detachably connected to the second part for pressing the adjusting block against the top of the die head body.

[0010] In some embodiments, the adjusting block has a contact ramp that abuts against the pressure plate, the contact ramp extending downward from the top of the adjusting block away from the first portion.

[0011] In some embodiments, a translation adjustment assembly is provided on the die head body. The translation adjustment assembly includes a mounting block, a screw rotatably mounted on the mounting block and connected at one end to the adjustment block, and an adjustment nut for moving the screw relative to the mounting block.

[0012] In some embodiments, the first part is provided with an interface for connecting to a feeding system, and the interface communicates with the inner cavity.

[0013] In some embodiments, the second part has a liquid storage tank communicating with the inner cavity, and the second part is provided with a sensor for monitoring the flow rate of slurry flowing into the liquid storage tank.

[0014] In some embodiments, a guide post is provided on the first part, and a guide hole is provided on the second part for the guide post to be inserted.

[0015] Compared with the prior art, the coating die head provided by this utility model includes a die head body with an inner cavity, an adjusting block, and a tape. The die head body includes a first part and a second part. The inner cavity extends to the top of the die head body and forms a slurry outlet on the surface of the top part. The adjusting block is movably disposed on the top of the die head body along the length direction of the die head body. The tape extends from the sealing end of the adjusting block to the end of the die head body and closes the slurry outlet located between the adjusting block and the end of the die head body.

[0016] The beneficial effects of the coating die head provided by this utility model are as follows: Compared with the prior art, when it is necessary to change the coating width, the coating die head of this utility model adjusts the position of the adjustment block on the die head body, adjusts the distance between the two adjustment blocks to the predetermined distance, and then removes the second part and applies tape of a predetermined length. In this way, the position of the adjustment block is adjusted first, and then the tape is applied to the die head body. The length of the tape is slightly longer than the distance between the adjustment block and the end of the die head body. This can accurately control the coating width on the base tape and avoid the error caused by manually measuring the tape length, which would affect the coating width requirement.

[0032] like Figures 1 to 9 As shown, the coating die 10 provided in this embodiment includes: a die body 11 for connecting to a feeding system (not shown) and having a rectangular longitudinal section; the die body 11 includes a detachably connected first part 12 and a second part 13, which are connected to form an inner cavity 14 for storing slurry; the inner cavity 14 extends to the top of the die body 11 and forms a slurry outlet 15 on the surface of the top; at least one adjusting block 16 for abutting against a coating roller 30; at least one adjusting block 16 is movably disposed on the top of the die body 11 along the length direction of the die body 11; the adjusting block 16 has an opposing liquid outlet end 161 and a sealing end 162; and a tape (not shown) extending from the sealing end 162 of the adjusting block 16 to the end of the die body 11 and closing the slurry outlet 15 located between the adjusting block 16 and the end of the die body 11.

[0033] The coating die 10 described above can accurately control the coating width on the base tape, avoiding excessive errors caused by manually measuring the tape length, which would affect the coating width requirements.

[0034] See Figures 1 to 5The slurry coating apparatus 100 provided in this embodiment includes a frame 101, a coating roller 30 rotatably mounted on the frame 101, a support device 20 located below the coating roller 30, and a coating die 10 mounted on the support device 20. It should be noted that the support device 20 is vertically mounted on the frame 101. The baseband passes between the coating die 10 and the coating roller 30. The coating die 10 is connected to a feeding system (not shown) for supplying slurry. The coating die 10 rises with the support device 20 and presses the baseband onto the coating roller 30, thereby coating the baseband with slurry at a predetermined width.

[0035] See Figures 1 to 9 The coating die head 10 provided in this embodiment includes a die head body 11, an adjustment block 16, and a transparent tape (not shown).

[0036] See Figures 6 to 9 In this embodiment, the die head body 11 is used to connect to the feeding system. The die head body 11 has, but is not limited to, a rectangular longitudinal section. The die head body 11 includes a detachably connected first part 12 and a second part 13, which are connected to form an inner cavity 14 for storing slurry. The inner cavity 14 extends to the top of the die head body 11 and forms a slurry outlet 15 on the surface of the top. In this embodiment, the lengths of the first part 12 and the second part 13 are substantially the same. The first part 12 is provided with an interface 12 for connecting to the feeding system. 1. Interface 121 connects to the inner cavity 14. The first part 12 and the second part 13 are detachably connected by fasteners such as screws. After the first part 12 and the second part 13 are fixedly connected, they enclose the inner cavity 14 to store the slurry flowing in from the feeding system. A slurry outlet 15 communicating with the inner cavity 14 is formed on the top surface of the die head body 11. The slurry outlet 15 extends along the length direction of the die head body 11. In this way, as the slurry is supplied by the feeding system, the slurry first enters the inner cavity 14 and then overflows from the slurry outlet 15 and is coated on the base tape.

[0037] Please continue reading Figures 6 to 9In this embodiment, an adjusting block 16 is provided on the die head body 11 for abutting against the coating roller 30. The adjusting block 16 is movably disposed on the top of the die head body 11 along the length direction of the die head body 11. The adjusting block 16 has an opposing liquid outlet end 161 and a sealing end 162. Adhesive tape extends from the sealing end 162 of the adjusting block 16 to the end of the die head body 11 and closes the slurry outlet 15 located between the adjusting block 16 and the end of the die head body 11. In this embodiment, the number of adjusting blocks 16 is, but not limited to, two. Adjusting blocks 16 are arranged alternately on the die head body 11, and each can move on the top of the die head body 11 along the length direction of the die head body 11. The adjusting blocks 16 cover the slurry outlet 15 in the width direction of the die head body 11. Each adjusting block 16 has a liquid outlet end 161 and a sealing end 162 that are opposite each other in the length direction. A tape is provided between each adjusting block 16 and the end of the die head body 11 adjacent to the adjusting block 16, that is, a tape is provided between the sealing end 162 of each adjusting block 16 and the end of the die head body 11. In this way, when it is necessary to change the coating width, the position of the adjusting block 16 on the die head body 11 is adjusted. After the distance between the two adjusting blocks 16 is adjusted to the predetermined distance, the second part 13 is removed and a tape of a predetermined length is applied. The length of the tape must be at least longer than the distance from the end of the die head body 11 to the sealing end 162 of the adjusting block 16. In this way, the coating width of the base tape can be precisely controlled after the tape is applied by positioning the adjusting block 16, so that the slurry is coated on the base tape with a predetermined width (along the length direction of the die head body 11).

[0038] See Figure 6 , Figure 8 and Figure 9 In this embodiment, a groove 131 is formed on the surface of the second part 13 that abuts against the first part 12. The groove 131 forms an inner cavity 14 when the first part 12 and the second part 13 are connected. Adhesive tape is adhered to the inner wall of the groove 131 of the second part 13. In this embodiment, the surface of the first part 12 facing the second part 13 is flat, and a groove 131 is formed on the surface of the second part 13 facing the first part 12. After the first part 12 and the second part 13 are fixedly connected, the groove 131 forms the aforementioned inner cavity 14. The adhesive tape is placed in the inner cavity 14 and located on the inner wall of the groove 131 of the second part 13. In this way, adhesive tape of a preset length is attached to the inner wall of the second part 13 to seal the slurry outlet 15 of that section.

[0039] In other embodiments, tape may be filled into the slurry outlet 15.

[0040] See Figure 6 and Figure 9In this embodiment, a groove 17 is provided on the top of the die head body 11. The groove 17 extends along the length of the die head body 11. An adjusting block 16 is movably disposed within the groove 17, and the slurry outlet 15 is located on the bottom surface of the groove 17. In this embodiment, the bottom of the adjusting block 16 abuts against the bottom surface of the groove 17, and one side of the adjusting block 16 abuts against the groove wall of the groove 17. This limits the outlet position and height of the slurry in the coating die head 10 and guides the movement of the adjusting block 16.

[0041] See Figures 6 to 9 In this embodiment, a pressure plate 18 is detachably connected to the second part 13, which is used to press the adjusting block 16 against the top of the die head body 11. The pressure plate 18 is detachably installed on the second part 13 with fasteners such as screws, and presses the adjusting block 16 down onto the die head body 11. In this way, after the adjusting block 16 is pressed tightly, it can prevent the adjusting block 16 from moving during the coating process, so as to ensure the coating accuracy.

[0042] See Figures 6 to 9 In this embodiment, the adjusting block 16 has a contact slope 163 that abuts against the pressure plate 18. The contact slope 163 extends downward from the top of the adjusting block 16 away from the first part 12. After the pressure plate 18 is installed, its top end is basically on the same plane as the top end of the adjusting block 16 and the top end of the first part 12. In this way, after the pressure plate 18 is locked, the pressure plate 18 can press the adjusting block 16 against the bottom surface and the wall of the trough 17 respectively. The slurry outlet space constructed between the first part 12, the adjusting block 16, and the pressure plate 18 can ensure that the slurry is coated on the base belt with a predetermined width, thereby improving the coating accuracy.

[0043] See Figure 1 and Figure 9 In this embodiment, the die head body 11 is provided with a translation adjustment assembly 19. The translation adjustment assembly 19 includes a mounting block 191, a screw 192 rotatably mounted on the mounting block 191 and connected at one end to an adjustment block 16, and an adjustment nut 193 for moving the screw 192 relative to the mounting block 191. In this embodiment, the mounting block 191 is fixed on the mounting base 22, the screw 192 extends along the length direction, and the number of adjustment nuts 193 is not limited to two, located on both sides of the mounting block 191 and threadedly connected to the screw 192. When the adjustment nuts 193 are rotated at the same time, the screw 192 can be driven to move the adjustment block 16, thereby enabling precise adjustment of the position of the adjustment block 16.

[0044] See Figure 6 , Figure 7 and Figure 9In this embodiment, the second part 13 is provided with a liquid storage tank 132 that communicates with the inner cavity 14. The second part 13 is provided with a sensor 133 for monitoring the flow rate of slurry flowing into the liquid storage tank 132. The sensor can monitor the flow rate of slurry and feed it back to the feeding system, thereby controlling the supply of slurry and ensuring the stability of the outflow of slurry, thereby ensuring the coating effect.

[0045] See Figure 7 and Figure 8 In this embodiment, the first part 12 is provided with a guide post 122, and the second part 13 is provided with a guide hole 134 for the guide post 122 to be inserted. In this way, the first part 12 and the second part 13 can be quickly positioned when the mold is closed.

[0046] Please return to the previous page. Figures 1 to 5 The slurry coating apparatus 100 provided in this embodiment includes a frame 101, a coating roller 30 rotatably mounted on the frame 101, a support device 20 vertically mounted on the frame 101 and located below the coating roller 30, and a coating die head 10 supported on the support device 20 and used to abut against the coating roller 30.

[0047] See Figures 1 to 4The support device 20 provided in this embodiment is used to install and support the coating die head 10. The support device 20 includes a base plate 21, a mounting base 22, a lifting power component 23, a support base 24, and a holding component 25. The mounting base 22 is supported on the base plate 21 in a lifting manner. The lifting power component 23 causes the mounting base 22 to rise and fall relative to the base plate 21. The support base 24 includes a support portion 241 for installing the coating die head 10 and pivot shaft portions 242 disposed at both ends of the support portion 241. The pivot shaft portions 242 are rotatably supported on the mounting base 22 and can rotate relative to the mounting base 22 about the axis of the pivot shaft portions 242. The holding component 25 is disposed between the support base 24 and the mounting base 22 and is used to hold the support base 24 on the mounting base 22. In this embodiment, the number of base plates 21 is not limited to two. The two base plates 21 are fixedly mounted on the frame 101 by screws, welding or any other existing fixing method. The number of mounting seats 22 is not limited to two, each corresponding to one of the two base plates 21. The mounting seats 22 are located above the base plates 21 and a lifting power component 23 is provided between them to drive the mounting seats 22 to rise and fall relative to the base plates 21. The number of pivot shafts 242 is not limited to two, each provided at both ends of the bearing portion 241 and connected to the mounting seats 22. After the coating die head 10 rotates to the position directly below the coating roller 30, the holding assembly 25 maintains the distance between the bearing base 24 and the mounting seat 22. To maintain the position and prevent relative rotation between the two, it is understood that the mounting base 22 is supported on the base plate 21 in a height-adjustable manner, and the bearing base 24 is rotatably supported on the mounting base 22 by means of a pivot shaft 242. The coating die 10 is mounted on the bearing part 241. In this way, when it is necessary to remove the coating die 10, the mounting base 22 is lowered to a predetermined height, and then the retaining component 25 releases the mounting base 22 from the bearing base 24. Then, the bearing part 241 of the bearing base 24 is rotated around the pivot shaft 242 by a predetermined angle. This facilitates the removal and installation of the coating die 10, improves work efficiency, and avoids bumping the coating die 10 during the removal and installation process.

[0048] See Figures 1 to 4 The retaining assembly 25 provided in this embodiment includes a retaining member 251 disposed on the bearing portion 241, a pin member 252 movably disposed on the mounting base 22, and a retaining power member 253 for moving the pin member 252 to abut against the pin member 252. In this embodiment, the bearing base 24 is mounted on the mounting base 22 in a manner that is not limited to unidirectional rotation. The retaining power member 253 is, but is not limited to, a cylinder, which is fixedly mounted on the mounting base 22. The pin member 252 is connected to the output shaft of the retaining power member 253. Under the drive of the retaining power member 253, the pin member 252 can abut against and separate from the retaining member 251.

[0049] In other embodiments, the retaining member 251 may be disposed on the mounting base 22, and the pin member 252 and the retaining power member 253 may be disposed on the bearing portion 241.

[0050] from Figure 4 As can be seen, in this embodiment, the mounting base 22 has a slot 221, which extends through both ends of the mounting base 22. A pin component 252 is movably disposed within the slot 221, with one end connected to the retaining power component 253, and the other end extending out of the slot 221 to abut against the retaining component 251. Thus, the pin component 252, installed within the mounting base 22, improves its anti-rotation strength and stability. Figure 3 As can be seen, in this embodiment, the retaining member 251 includes a column member 254 fixed on the bearing portion 241 and a wheel member 255 rotatably mounted on the column member 254 and used to abut against the pin member 252. In this way, the friction between the two can be reduced by the wheel member 255, and wear can be reduced when the retaining member 251 and the pin member 252 of the retaining assembly 25 are connected.

[0051] See Figure 1 , Figure 3 and Figure 4 In this embodiment, a locking assembly 26 is provided on the mounting base 22. The locking assembly 26 includes a locking plate 261 fixed on the mounting base 22. The locking plate 261 has a locking hole through which the pivot shaft portion 242 passes. A locking screw 262 is provided on the locking plate 261 for locking and loosening the pivot shaft portion 242. In this way, the size of the locking hole can be adjusted by the locking screw 262. After locking the pivot shaft portion 242, the stability of the structure can be further improved. After loosening the pivot shaft portion 242, the pivot shaft portion 242 can be rotated relative to the mounting base 22.

[0052] See Figure 1 , Figure 3 and Figure 4 In this embodiment, an operating handle 27 is provided on the pivot shaft 242, and the operating handle 27 is set off from the axis of the pivot shaft 242.

[0053] See Figures 1 to 4 In this embodiment, the lifting power component 23 is, but is not limited to, a lifting cylinder. The cylinder body of the lifting cylinder is fixedly mounted on the base plate 21, and the output axis of the lifting cylinder extends upward and is fixedly connected to the mounting base 22.

[0054] from Figure 3 and Figure 4 As can be seen, in this embodiment, the supporting part 241 has a hollow groove 243, which extends along the length of the supporting part 241. This can reduce the overall weight and manufacturing cost.

[0055] See Figures 1 to 4 In this embodiment, the coating die head 10 is fixed on the top of the bearing part 241, and a counterweight shaft 28 is fixed on the bottom of the bearing part 241 opposite to the top. In this way, the rotating structure has good stability and the bearing base 24 is rotated more effortlessly.

[0056] See Figures 1 to 5 The slurry coating apparatus 100 provided in this embodiment also includes a gap adjustment device 40 disposed between the frame 101 and the support device 20. The gap adjustment device 40 includes a drive assembly 41 and a first wedge 42 and a second wedge 43 that cooperate with each other at an inclined plane. The drive assembly 41 drives the first wedge 42 to move relative to the second wedge 43 to adjust the gap between the coating die 10 and the coating roller 30. In this way, by driving the first wedge 42 to move relative to the second wedge 43 through the drive assembly 41, the coating die 10 and the coating roller 30 move relative to each other, thereby realizing the separation and contact between the coating die 10 and the coating roller 30. In this way, when coating is not required, the gap adjustment device 40 can be controlled to quickly separate the coating die 10 and the coating roller 30, and when coating needs to continue, the gap adjustment device 40 can be controlled to quickly contact the coating die 10 and the coating roller 30, thereby improving the coating efficiency and accurately controlling the position of the coating die 10 to ensure a more uniform coating thickness.

[0057] See Figures 1 to 5 In this embodiment, the first wedge 42 is disposed on the support device 20 and fixedly connected to the support device 20, and the drive assembly 41 is fixedly installed on the frame 101 and connected to the second wedge 43. In this embodiment, the first wedge 42 is disposed on the mounting base 22 of the support device 20, and the first wedge 42 and the mounting base 22 are fixedly connected by fasteners such as screws. The drive assembly 41 is fixedly installed on the frame 101 and connected to the second wedge 43. It should be noted that when it is necessary to quickly separate the coating die head 10 from the coating roller 30, the drive assembly 41 drives the second wedge 43 to move towards the first wedge 42. When it is necessary to abut the coating die head 10 against the coating roller 30, the drive assembly 41 drives the second wedge 43 to move away from the first wedge 42, and at the same time, the lifting power component 23 pushes the coating die head 10 upward.

[0058] from Figure 5As can be seen, the drive assembly 41 provided in this embodiment includes a lead screw assembly 411 and a servo motor 412 that moves the lead screw assembly 411 to drive the second wedge 43 to move. The servo motor 412 is fixedly mounted on the frame 101. The lead screw in the lead screw assembly 411 is rotatably supported on the frame 101 and connected to the servo motor 412, and rotates under the drive of the servo motor 412. The nut seat in the lead screw assembly 411 is fixedly connected to the second wedge 43. In this way, the movement of the second wedge 43 can be quickly and accurately controlled by the servo motor 412, thereby making the up-and-down movement of the coating die head 10 more precise.

[0059] from Figure 1 and Figure 4 As can be seen, the frame 101 provided in this embodiment is provided with a limiting post 44, which is used to abut against the mounting seat 22 of the bearing device 20 to limit the upward movement of the mounting seat 22 of the bearing device 20. The limiting post 44 is located on one side of the gap adjustment device 40. In this way, it can prevent the mounting seat 22 from moving too much upward and causing the coating die head 10 to collide with the coating roller 30.
