Description

Technical Field

[0001] The present invention relates to the field of battery pole piece coating, in particular to a material blocking component and a coating machine. Background Art

[0002] The battery's pole piece is coated by a coating machine. Figures 1 to 5 The coating machine in the prior art shown includes a scraper B100, a coating roller B200, a material plate B300, and a material baffle mounting plate B400. The material baffle mounting plate B400 includes a mounting bracket B410, a material baffle plate B420, and a sponge B430, and the mounting bracket B410 and the material baffle plate B420 are fixedly connected. A material trough is formed between the scraper B100, the coating roller B200, the material plate B300, and the two material baffle mounting plates B400, and the slurry is contained in the material trough. A coating port is provided between the coating roller B200 and the scraper B100. During coating, the coating roller B200 rotates, driving the foil to move linearly. When the foil passes through the coating port, the slurry will be evenly coated on the foil, and the height of the coating port determines the thickness of the coating. The material baffle mounting plate B400 can block the slurry on both sides of the material trough to prevent the slurry from flowing out.

[0003] Since the coating roller B200 rotates, the coating roller B200 and the baffle mounting plate B400 cannot fit tightly together, resulting in a gap between the coating roller B200 and the baffle mounting plate B400. The slurry in the material tank easily flows out of the gap. For example, Chinese patent No. 201721275808.2 discloses a baffle mechanism for a lithium battery coating machine, including a fixed bracket and a baffle plate. The baffle plate is fixed to the fixed bracket by a limit block, and the position of the baffle plate and the fixed bracket is relatively fixed. When the fixed bracket is fixed to the bottom plate, the position of the baffle plate will also be fixed. If there is a gap between the baffle plate and the coating steel roller, the slurry will still flow out of the gap. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a material blocking assembly that prevents slurry from flowing out of the gap.

[0005] The material blocking assembly of the present invention includes a mounting part and a material blocking part. The material blocking assembly also includes a first fixing part. The mounting part is used to be fixed to the material plate. The mounting part is provided with a mounting groove. The material blocking part is slidably arranged in the mounting groove. The material blocking part is used to abut against the material plate. The material blocking part is used to abut against the scraper and the coating roller respectively. The first fixing part is movably connected to the material blocking part to press and fix the material blocking part to the material plate.

[0006] In one embodiment, the first fixing member is arranged on a side close to the scraper and / or the coating roller.

[0007] In one embodiment, the mounting member includes a top surface adjusting portion, and the first fixing member is movably connected to the top surface adjusting portion to adjust the position of the material blocking member in the first direction.

[0008] In one embodiment, the material blocking assembly includes a second fixing member, which is used to press the material blocking member toward the installation groove, and there is an angle between the action direction of the first fixing member and the action direction of the second fixing member.

[0009] In one embodiment, the material blocking assembly includes a pressing piece, the mounting slot has an insertion opening, the pressing piece movable cover is provided at the insertion opening, and the second fixing piece is connected to the pressing piece.

[0010] In one embodiment, the second fixing member is movably connected to the pressing member to adjust the position of the baffle plate in the second direction.

[0011] In one embodiment, the pressing member is movably connected to the mounting member.

[0012] In one embodiment, the material blocking assembly includes a third fixing member, and the third fixing member is used to fix the material blocking plate in the installation groove.

[0013] In one embodiment, the mounting member includes a side adjustment portion, and the third fixing member is movably connected to the side adjustment portion to adjust the position of the baffle plate in the third direction.

[0014] The present application also provides a coating machine, which includes the material blocking assembly described in any of the above embodiments.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. Since the mounting member and the material stopper can slide relative to each other, the mounting member can be first fixed to the material plate, and then the material stopper can be placed in the mounting groove. By sliding the material stopper in the mounting groove, the material stopper can be closely attached to the coating roller. After the position of the material stopper is adjusted, the position of the material stopper is fixed by the first fixing member. In this way, the material stopper can be closely attached to the coating roller during the coating process.

[0017] 2. By sliding the stopper, the stopper can be close to the scraper to prevent the slurry from flowing out of the gap between the scraper and the stopper.

[0018] 3. By sliding the stopper, the stopper can penetrate into the coating port between the scraper and the coating roller to prevent the slurry from flowing out of the coating port.

[0019] 4. When adjusting the position of the stopper, there is no need to disassemble, install and adjust the installation parts again. It is sufficient to adjust the position of the stopper in the installation groove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] See also Figures 6 to 12 The material blocking component 10 of one embodiment includes a mounting member 100 and a material blocking member 200. The material blocking component 10 also includes a first fixing member 300. The mounting member 100 is used to be fixed to the material plate 20. The mounting member 100 is provided with a mounting groove 110. The material blocking member 200 is slidably arranged in the mounting groove 110. The material blocking member 200 is used to abut against the material plate 20. The material blocking member 200 is used to abut against the scraper 30 and the coating roller 40 respectively. The first fixing member 300 is movably connected to the material blocking member 200 to press the material blocking member 200 and fix it to the material plate 20.

[0042] The mounting member 100 is used to secure the material stopper assembly 10. First, secure the mounting member 100 to the material plate 20, and then install the other components of the material stopper assembly 10. The position of the material stopper assembly 10 on the material plate 20 can be adjusted by adjusting the position of the mounting member 100 on the material plate 20. The mounting member 100 is used to mount the material stopper 200 on the material plate 20. The material stopper 200 is used to block the slurry. The material stopper 200 is positioned within the mounting groove 110 and can slide within the mounting groove 110. When the material stopper 200 slides toward the side closer to the scraper 30 and coating roller 40, the material stopper 200 presses against the scraper 30 and coating roller 40, increasing the depth of the material stopper 200's insertion into the coating opening between the scraper 30 and coating roller 40. When the material stopper 200 slides away from the scraper 30 and coating roller 40, the pressure of the material stopper 200 on the scraper 30 and coating roller 40 decreases, and the depth of the material stopper 200's insertion into the coating opening decreases. The material stopper 200 abuts against the material plate 20 to prevent the slurry from flowing out of the gap between the material stopper 200 and the material plate 20. The first fixing member 300 can be a pressing plate, which is pressed against the groove wall of the installation groove 110 by a motor or a cylinder for fixing. The first fixing member 300 can also be a fixing clamp, which clamps the material stopper plate 210 to the installation member 100.

[0043] In summary, the degree of compression between the material blocking component 10 and the scraper 30 and the coating roller 40 can be adjusted, so that the material blocking member 200 can be tightly attached to the coating roller 40, so that when the coating roller 40 rotates, the slurry is prevented from flowing out of the gap between the coating roller 40 and the material blocking member 200. Moreover, by adjusting the position of the material blocking member 200 in the mounting groove 110, the degree of compression between the scraper 30 and the material blocking member 200 is adjusted, thereby preventing the slurry from flowing out of the gap between the scraper 30 and the material blocking member 200. Sliding the material blocking member 200 in the mounting groove 110 can also change the depth of the material blocking member 200 inserted into the coating port, thereby preventing the slurry from flowing out of the coating port. When adjusting the position of the material blocking member 200, there is no need to disassemble, install and adjust the mounting member 100 again, and the position of the material blocking member 200 in the mounting groove 110 can be adjusted.

[0044] In order to make the stopper 200 close to the scraper 30 and the coating roller 40, see Figure 7 In one embodiment, the material retaining member 200 includes a material retaining plate 210 and a sponge 220. The sponge 220 is mounted on the material retaining plate 210 and abuts against the scraper 30 and the coating roller 40. In order to prevent the slurry from flowing out of the gap between the material plate 20 and the material retaining member 200, the sponge 220 further abuts against the material plate 20. In order to mount the sponge 220 on the material retaining plate 210, the material retaining member 200 further defines a first sponge mounting groove on the side facing the scraper 30, and the sponge 220 is mounted in the first sponge mounting groove; and / or, the material retaining member 200 defines a second sponge mounting groove on the side facing the coating roller 40, and the sponge 220 is mounted in the second sponge mounting groove; and / or, the material retaining member 200 defines a third sponge mounting groove on the side facing the material plate 20, and the sponge 220 is mounted in the third sponge mounting groove. To facilitate installation of the sponge 220, in one embodiment, the first, second, and third sponge mounting slots are interconnected, with the sponges 220 in the first, second, and third sponge mounting slots connected sequentially. Furthermore, the sponges 220 in the first, second, and third sponge mounting slots are integrated. To further stabilize the installation of the sponges 220, in one embodiment, a fourth sponge mounting slot is defined on the side of the material retaining member 200 facing away from the material plate 20. The sponge 220 in the fourth sponge mounting slot is installed in an integrated manner with the sponge 220 in the first sponge mounting slot. The bottom support of the fourth sponge mounting slot supports the sponge in the fourth sponge mounting slot while also supporting the sponges 220 in the first, second, and third sponge mounting slots.

[0045] To better secure the sponge 220, in one embodiment, the first fixing member 300 is movably connected to the sponge 220. Furthermore, the first fixing member 300 movably presses the sponge 220 and presses the sponge 220 against the material blocking plate 210. Furthermore, the first fixing member 300 presses the sponge 220 into the fourth sponge mounting groove.

[0046] To strengthen the connection between the mounting member 100 and the sheet 20, in one embodiment, the mounting member 100 is made of metal. For example, the mounting member 100 may be made of at least one of iron, cobalt, nickel, copper, and aluminum. Furthermore, the mounting member 100 and the sheet 20 may be made of steel. To strengthen the connection between the retaining plate 210 and the mounting member 100, the retaining plate 210 may be made of plastic, such as polyformaldehyde (POM).

[0047] In order to fix the position of the stopper 200 after adjustment, see Figure 7 and Figure 8 In one embodiment, the first fixing member 300 includes a first fixing bolt, the outer peripheral wall of which is provided with a first bolt helical meshing tooth. The mounting member 100 is provided with a first fixing screw hole, which is connected to the mounting groove 110. The side wall of the first fixing screw hole is provided with a first screw hole helical meshing tooth. The first fixing bolt is inserted into the first fixing screw hole, and the first bolt helical meshing tooth is engaged with the first screw hole helical meshing tooth. The first fixing bolt abuts against the material stopper 200 to press and fix the material stopper 200. After the position of the material stopper 200 is adjusted, the first fixing bolt is rotated downward to press the material stopper 200 against the material plate 20 for fixation. In order to allow the first fixing bolt to flexibly adapt to the placement of the material stopper 200, in one embodiment, there are at least two first fixing bolts and at least two first fixing screw holes. Each first fixing bolt is inserted into a first fixing screw hole, and each first fixing bolt abuts against the material stopper 200. When the arrangement position of the stopper 200 changes, the position of the stopper 200 toward the first fixing bolt also changes. In order to adapt to the change in the arrangement position of the stopper 200, the length of each first fixing bolt penetrating into the mounting groove 110 is adjusted so that each first fixing bolt can continue to press the stopper 200.

[0048] In order to enable the material blocking member 200 to press the scraper 30 and the coating roller 40, see Figure 6 and Figure 7In one embodiment, the first fixing member 300 is disposed on a side close to the scraper 30 and / or the coating roller 40. By disposing the first fixing member 300 on a side close to the scraper 30 and / or the coating roller 40, the action point of the material blocking member 200 is disposed on a side close to the scraper 30 and / or the coating roller 40. The first fixing member 300 presses the material blocking member 200 on the side close to the scraper 30 and / or the coating roller 40, and the material blocking member 200 is closely attached to the scraper 30 and / or the coating roller 40, thereby preventing the slurry from flowing out.

[0049] To adjust the placement of the baffle plate 210, see Figure 8 and Figure 9 In one embodiment, the mounting member 100 includes a top surface adjustment portion 140, and the first fixing member 300 is movably connected to the top surface adjustment portion 140 to adjust the position of the material stopper 200 in the first direction. The material stopper 200 is slid in the first direction so that it is in close contact with the scraper 30 and the coating roller 40. The first fixing member 300 is then adjusted within the top surface adjustment portion 140. The first fixing member 300 moves relative to the top surface adjustment portion, pressing against the material stopper 210 to secure it. In order to connect the first fixing member 300 to the top surface adjustment portion 140, in one embodiment, a first fixing screw hole is defined within the top surface adjustment portion 140.

[0050] In order to adjust the placement position of the baffle plate 210 more flexibly, see Figure 11 and Figure 13 In one embodiment, the material stopper assembly 10 includes a second fixing member 400, which is used to press the material stopper 200 against the mounting groove 110. The direction of action of the first fixing member 300 and the direction of action of the second fixing member 400 are at an angle. The second fixing member 400 is used to adjust the position of the material stopper 200. The first fixing member 300 and the second fixing member 400 press and fix the material stopper 200 in different directions, making the position adjustment of the material stopper 200 more flexible. The second fixing member 400 can be an outer end pressure plate, and a drive device is installed on the frame. The power output of the drive device is connected to the outer end pressure plate, and the outer end pressure plate is movably pressed against the material stopper plate 210.

[0051] In order to facilitate the adjustment of the baffle plate 210, see Figure 11 and Figure 13In one embodiment, the action direction of the first fixing member 300 is from the side close to the top of the baffle member 200 to the side close to the bottom of the baffle plate 210, and the action direction of the second fixing member 400 is toward the scraper 30 and / or the coating roller 40. Furthermore, the action direction of the first fixing member 300 is perpendicular to the action direction of the second fixing member 400. The top of the baffle plate 210 is abutted with the first fixing member 300, and the first fixing member 300 can support the front of the baffle plate 210 so that the front of the baffle plate 210 can be adjusted up and down. The point of action of the force of the first fixing member 300 is in front of the baffle plate 210, ensuring that the sponge 220 is in close contact with the scraper 30 and the coating roller 40 respectively. The rear part of the baffle plate 210 is provided with the second fixing member 400, and the second fixing member 400 can support the rear part of the baffle plate 210 so that the baffle plate 210 can be adjusted in the front and rear directions, ensuring that the sponge 220 is in close contact with the scraper 30 and the coating roller 40 respectively.

[0052] In order to facilitate the installation of the material blocking member 200 into the installation groove 110, see Figure 13 In one embodiment, the material stopper assembly 10 includes a compression member 600. The mounting slot 110 has an insertion opening 120. The compression member 600 is movably mounted on the insertion opening 120, and the second fixing member 400 is connected to the compression member 600. When the material stopper 200 needs to be installed, the compression member 600 is opened from the insertion opening 120 and inserted into the mounting slot 110 from the insertion opening 120. After the position of the material stopper 200 in the mounting slot 110 is adjusted, the compression member 600 is mounted on the insertion opening 120, and the second fixing member 400 is adjusted to secure the material stopper 200. The compression member 600 can be mounted on the insertion opening 120 through a movably mounted frame cover and movably abuts against the mounting member 100. To facilitate the mounting of the compression member 600 on the insertion opening 120, in one embodiment, the compression member 600 is movably connected to the mounting member 100. Furthermore, the compression member 600 and the mounting member 100 are connected by a clamping bolt 610. The pressure piece 600 can be removed from the mounting piece 100 or the fixing piece can be connected to the mounting piece 100 by loosening or tightening the pressure bolt 610. Furthermore, the pressure piece 600 is provided with a pressure-fixing through hole, and the mounting piece 100 is provided with a fixed piece screw hole 162. The side wall of the fixed piece screw hole 162 is provided with fixed piece helical meshing teeth. The side wall of the pressure-fixing bolt 610 is provided with pressure-fixing helical meshing teeth. The fixed piece bolt is inserted into the pressure-fixing through hole and the fixed piece screw hole 162, and the fixed piece helical meshing teeth and the pressure-fixing helical meshing teeth are driven.

[0053] To adjust the stopper 200, see Figure 13In one embodiment, the second fixing member 400 is a second fixing bolt, the outer peripheral wall of which is provided with second bolt helical meshing teeth. The pressing member 600 defines a second fixing screw hole, the side wall of which is provided with second screw hole helical meshing teeth. The second fixing bolt is inserted into the second fixing screw hole and abuts against the material stopper 200. By rotating the second fixing bolt, the depth of the second fixing bolt inserted into the mounting slot 110 is changed, and the material stopper 200 is pressed to different positions, thereby adjusting the position of the material stopper 200.

[0054] In order to adjust the position of the material blocking member 200 by the second fixing member 400 after the pressing member 600 is covered on the insertion port 120, see Figure 13 In one embodiment, the second fixing member 400 is movably connected to the pressing member 600 to adjust the position of the blocking plate 210 in the second direction.

[0055] In order to facilitate the installation of the material blocking member 200 into the installation groove 110, see Figure 6 、 Figure 8 and Figure 9 In one embodiment, the mounting member 100 is provided with a convenient installation opening 130, which is connected to the insertion opening 120, and is in turn connected to the mounting slot 110. The connected convenient installation opening 130 and the insertion opening 120 reserve sufficient space for the material stopper 200 to be installed in the mounting slot 110, making it easier for the material stopper 200 to be installed in the mounting slot 110. To further facilitate the insertion of the material stopper 200, the convenient installation opening 130 further includes a first installation opening 131 and a second installation opening 132, the first installation opening 131 and the second installation opening 132 being connected to the insertion opening 120, and an angle being formed between the extending direction of the first installation opening 131 and the extending direction of the second installation opening 132. Thus, the material stopper 200 can be installed in the mounting slot 110 from multiple directions. To facilitate the installation of the retaining member 200, in one embodiment, the angle between the extension direction of the first mounting opening 131 and the extension direction of the second mounting opening 132 is greater than or equal to 90 degrees. To facilitate the installation of the retaining member 200 corresponding to the scraper 30, the coating roller 40, and the material sheet 20, in one embodiment, the first mounting opening 131 near the mounting groove 110 faces the scraper 30 and the coating roller 40, and the second mounting opening 132 near the mounting groove 110 faces the material sheet 20.

[0056] In order to stabilize the position of the blocking member 200 in the mounting groove 110, see Figure 11 and Figure 13In one embodiment, the material retaining assembly 10 includes a third fixing member 500, which is used to fix the material retaining plate 210 in the mounting groove 110. By placing the material retaining plate 210 in the mounting groove 110 of the mounting member 100, and by fine-tuning the first fixing member 300 at the top surface adjustment portion 140 and the second fixing member 400 at the pressing member 600, the angle and front-back position of the material retaining plate 210 are adjusted so that the sponge 220 on the material retaining plate 210 is tightly fitted with the scraper 30, the coating roller 40, and the material plate 20, respectively. In this way, the material retaining plate 210 can be fixed to the side of the mounting member 100 by the third fixing member 500. In order to fix the material retaining plate 210, in one embodiment, the third fixing members 500 are respectively connected to two opposite sides of the material retaining plate 210. The third fixing members 500 on both sides support and fix the material retaining plate 210. The third fixing member 500 can be connected to the frame, and the frame can be controlled to enable the third fixing member 500 to be movably connected to the material retaining plate 210. For example, the third fixing member 500 can be a side pressure plate. A cylinder is installed on the frame, and the power output end of the cylinder is connected to the side pressure plate, so that the side pressure plate is movably pressed against the side of the material retaining plate 210 to fix it. To further stabilize the material retaining plate 210, in one embodiment, at least two third fixing members 500 are provided on each of two opposing sides of the material retaining plate 210, and each third fixing member 500 is movably connected to the material retaining member 200.

[0057] In order to fix the material stopper 200 on the side of the material stopper 200, see Figure 9 In one embodiment, the mounting member 100 includes a side adjustment portion 150, and the third fixing member 500 is movably connected to the side adjustment portion 150 to adjust the position of the material stopper 210 in the third direction. In order to set the third fixing member 500 on both sides of the material stopper 200, further, at least two side adjustment portions 150 are provided, each of which is connected to the top adjustment portion 140, and the side adjustment portions 150 are provided on opposite sides of the material stopper 200. In order to facilitate adjustment of the material stopper 200 through the third fixing member 500, in one embodiment, the third fixing member 500 is a third fixing bolt, and the outer peripheral wall of the third fixing bolt is provided with a third bolt helical meshing tooth. The side adjustment portion 150 is provided with a third fixing screw hole, and the side wall of the third fixing screw hole is provided with a third screw hole helical meshing tooth. The third fixing bolt is inserted into the third fixing screw hole, and the third bolt helical meshing tooth and the third screw hole helical meshing tooth are driven.

[0058] In order to more flexibly adjust the position of the material stopper 200, in one embodiment, the width of the mounting groove 110 is greater than the width of the material stopper 200, and / or the distance between the two side adjustment portions 150 is greater than the width of the material stopper 200. By adjusting the third fixing bolts screwed to the side adjustment portions 150 on both sides of the mounting groove 110, the depth of the third fixing bolts on both sides penetrating into the mounting groove 110 is changed, thereby changing the position of the material stopper 200.

[0059] To mount the mounting element 100 on the sheet 20, see Figure 9 In one embodiment, the mounting member 100 defines a slot 160 , and the material plate 20 is inserted into the slot 160 .

[0060] In order to adjust the position of the stopper 200 more flexibly, see Figures 9 to 13 In one embodiment, the slot 160 is connected to the mounting slot 110. Connecting the slot 160 and the mounting slot 110 allows the stopper 200 to be positioned in the slot 160, thereby increasing the movable space of the stopper 200, increasing the placement angle of the stopper 200, making the adjustment of the stopper 200 more flexible, reducing the weight of the stopper 200, and facilitating the processing of the slot 160 and the mounting slot 110.

[0061] In order to more flexibly adjust the placement position of the stopper 200, in one embodiment, the depth of the slot 160 is greater than the thickness of the sheet 20. Thus, when the mounting member 100 is mounted on the sheet 20 through the slot 160, the mounting member 100 can move in the direction of the depth of the slot 160. After the stopper 200 is installed into the mounting groove 110, the position of the stopper 200 can be adjusted in the depth direction of the slot 160, that is, the adjustment in the direction of action of the first fixing member 300 can adjust the stopper 200 upward or downward. After the position of the stopper 200 is adjusted, the stopper 200 is pressed and fixed to the sheet 20 by the first fixing member 300, so that one side of the sheet 20 abuts the stopper 200, and the other side of the sheet 20 abuts the bottom of the slot 160. In order to strengthen the connection between the mounting member 100 and the sheet 20, see Figure 13 In one embodiment, the retaining assembly 10 further includes a mounting bolt with mounting bolt meshing teeth disposed on its sidewalls. A socket 161 is defined at the bottom of the slot 160, and helical meshing teeth are disposed on its sidewalls. The mounting bolt passes through the socket 161, and the mounting bolt meshing teeth and the helical meshing teeth of the socket 161 engage in a transmission. Once the mounting member 100 is positioned correctly, the mounting bolt is rotated to press against the sheet 20, securing the mounting member 100.

[0062] When the thickness of the coating is different, the height of the coating opening between the scraper 30 and the coating roller 40 needs to be adjusted. In order to make the sponge 220 adapt to the change of the coating opening, the scraper 30 and the coating roller 40 are pressed tightly in the coating opening. Figure 14In one embodiment, the sponge 220 includes at least two sponge sub-layers 221, and each sponge sub-layer 221 is connected in sequence along the axial direction of the coating roller 40. Each sponge sub-layer 221 is provided with a plurality of compression holes 222, and the axial direction of the compression holes 222 is the same as the axial direction of the coating roller 40. When the height of the coating port is reduced, the compression sponge 220 causes the compression holes 222 to be squeezed, and the sponge 220 can produce a greater deformation, so that the sponge 220 can continue to be pressed in the coating port. In order to prevent the slurry from flowing out of the compression holes 222, in one embodiment, the compression holes 222 of two adjacent sponge sub-layers 221 are staggered. In order to reduce the outflow of slurry from the compression holes 222, see Figure 15 In one embodiment, a rubber stopper 700 is provided in each compression through-hole 222, and the rubber stopper 700 abuts against the side wall of the compression through-hole 222. The rubber stopper 700 can be fixed in the compression through-hole 222 by glue. In order to better prevent the slurry from flowing out, in one embodiment, rubber stops 700 are respectively provided at both ends of each compression through-hole 222. In order to better prevent the slurry from flowing out, in one embodiment, of the two rubber stops 700 of each compression through-hole 222, the width of the compression through-hole 222 close to the material trough is smaller than the width of the compression through-hole 222 away from the material trough, and the width of the rubber stopper 700 close to the material trough is smaller than the width of the rubber stopper 700 away from the material trough. By reducing the width of the compression through-hole 222 close to the material trough and the width of the rubber stopper 700, the slurry in the material trough is better prevented from flowing out. In order to enable the rubber stopper 700 to support the sponge 220, the sponge 220 is stretched outward to press the coating roller 40 and the scraper 30, see Figure 16In one embodiment, the rubber stopper 700 includes a top support block 710, a bottom support block 720, and at least two support posts 730. The top support block 710 has an arcuate cross-section and abuts against the top sidewall of the compression hole 222. The bottom support block 720 has an arcuate cross-section and abuts against the bottom sidewall of the compression hole 222. One end of each support post 730 is connected to the top support block 710, and the other end is connected to the bottom support block 720. In order to push the sponge 220 upward and downward, and to compress the scraper 30 above and the coating roller 40 below, in one embodiment, one end of the support post 730 faces the scraper 30, and the other end faces the coating roller 40. In order to better support the sponge 220, in one embodiment, the material blocking assembly 10 also includes at least two connecting top rods 810 and at least one connecting bottom rod 820, one end of each connecting top rod 810 is connected to the arc top support block 710 of a rubber stopper 700, and the other end is connected to the arc top support block 710 of another rubber stopper 700, one end of each connecting bottom rod 820 is connected to the arc bottom support block 720 of a rubber stopper 700, and the other end is connected to the arc bottom support block 720 of another rubber stopper 700. To better support the top connecting rod 810, the bottom connecting rod 820, the top arc support block 710, and the bottom arc support block 720, in one embodiment, the material retaining assembly 10 further includes a supporting rubber ball 830. A plurality of radiating rods 840 are connected to the supporting rubber ball 830. At least some of the radiating rods 840 are connected to the top connecting rod 810, at least some of the radiating rods 840 are connected to the bottom connecting rod 820, at least some of the radiating rods 840 are connected to the top arc support block 710, and at least some of the radiating rods 840 are connected to the bottom arc support block 720. Furthermore, the top arc support block 710 is fixedly connected to the inner circumferential wall of the compression hole by gluing, and is disposed at one end near the scraper. Furthermore, the bottom arc support block 720 is fixedly connected to the inner circumferential wall of the compression hole by gluing, and is disposed at one end near the coating roller. The top arc support block is gluingly fixed to the sponge sublayer 221.

[0063] Furthermore, the outer wall of the top support block 710 is provided with a first embedded rib, and the compression through-hole 222 is formed with a first embedded groove. The first embedded rib snaps into the first embedded groove, positioning and securing the top support block 710 within the compressed sponge 220. This also increases the fixed connection surface between the top support block 710 and the compressed sponge 220, thereby improving the adhesive bonding of the top support block 710 to the compressed sponge 220. To strengthen the connection between the first embedded rib and the sponge, the sidewalls of the first embedded groove are further provided with a plurality of first reinforcement grooves. The first embedded ribs are attached to a plurality of first reinforcement protrusions, each of which is disposed in the first reinforcement groove. To prevent the first reinforcement protrusion from falling out of the first reinforcement groove, the width of the first reinforcement protrusion at the notch of the first reinforcement groove is smaller than the width of the first reinforcement protrusion within the first reinforcement groove, and the width of the first reinforcement groove at the notch of the first reinforcement groove is smaller than the width of the first reinforcement protrusion within the first reinforcement groove. To facilitate assembly and disassembly, the first reinforcement protrusion is a hollow rubber ball, and the first reinforcement groove is spherical. Thus, it can be disassembled and assembled by squeezing the first reinforcement protrusion. The arc bottom support block is glued and fixed to the sponge layer 221.

[0064] The outer wall of the arc-bottom support block 720 is provided with a second embedded rib, and the compression through-hole 222 is formed with a second embedded groove. The second embedded rib snaps into the second embedded groove, positioning and fixing the arc-bottom support block 720 within the compressed sponge 220. This also increases the fixed connection surface between the arc-bottom support block 720 and the compressed sponge 220, thereby better adhering and fixing the arc-bottom support block 720 to the compressed sponge 220. To strengthen the connection between the second embedded rib and the sponge, the sidewalls of the second embedded groove are further provided with a plurality of second reinforcement grooves. The second embedded ribs are provided on a plurality of second reinforcement protrusions, and the second reinforcement protrusions are provided in the second reinforcement grooves. To prevent the second reinforcement protrusions from falling out of the second reinforcement grooves, the width of the second reinforcement protrusions at the notch of the second reinforcement groove is smaller than the width of the second reinforcement protrusion within the second reinforcement groove, and the width of the second reinforcement groove at the notch is smaller than the width of the second reinforcement protrusion within the second reinforcement groove. In order to facilitate disassembly and assembly, the second reinforcement protrusion is a hollow rubber ball, and the second reinforcement groove is spherical. Thus, the second reinforcement protrusion can be disassembled and assembled by squeezing.

[0065] In order to allow the compression hole to produce greater deformation during extrusion, in one embodiment, the curvature of the top arc support block 710 and the curvature of the bottom arc support block 720 are each less than 0.5π. In order to better compress the compression hole, further, the curvature of the top arc support block 710 is greater than the curvature of the bottom arc support block 720, or the curvature of the bottom arc support block 720 is greater than the curvature of the top arc support block 710. In order to better allow the compression hole to produce deformation, in one embodiment, the top arc support block 710 and the bottom arc support block 720 are staggered with each other, that is, the circle where the top arc support block 710 and the circle where the bottom arc support block 720 are located are respectively located on two parallel planes. As a result, when the compression hole is extruded, the top arc support block 710 and the bottom arc support block 720 are staggered with each other, avoiding mutual obstruction between the top arc support block 710 and the bottom arc support block 720. To increase the deformation of the compression hole, in one embodiment, each support column 730 is tilted, that is, the axis of each support column is offset from the center of the circle of the top support block 710 and the center of the circle of the bottom support block 720. When the compression hole is compressed, the two ends of the support column can be offset from each other and approach the center of the compression hole.

[0066] In order to better compress the scraper and coating roller against the sponge, in one embodiment, the sponge includes a scraper sponge and a coating roller sponge, the scraper sponge abuts the scraper, the coating roller sponge abuts the coating roller, the compression holes include a scraper compression hole and a coating roller compression hole, the scraper compression hole is opened in the scraper sponge, and the coating roller compression hole is opened in the coating roller sponge. One end of the support column in the scraper compression hole faces the scraper and the other end faces the material baffle, while one end of the support column in the coating roller compression hole faces the coating roller and the other end faces the material baffle. Furthermore, each sponge sublayer includes a scraper sponge and a coating roller sponge, and each sponge sublayer has a scraper compression hole and a coating roller compression hole.

[0067] To enable the stopper 200 to press against the scraper 30 and the coating roller 40, in one embodiment, a tightening post is provided on the stopper 200, and a guide member is provided on the mounting member 100. The guide member is disposed between the tightening post and the coating roller 40. The guide member defines a guide groove extending in an arc shape. The tightening post is located at the center of the circle in which the guide groove is located, with the notch of the guide groove facing the tightening post. A sliding block is slidably disposed within the guide groove and secured to the guide member via a guide fixture. An elastic cord is connected between the tightening post and the guide block. The sliding member tightens the tightening post via the elastic cord, thereby pulling the stopper 200 toward the scraper 30 and the coating roller 40, causing the stopper 200 to press against the scraper 30 and the coating roller 40. Furthermore, by sliding the guide fixture in the guide groove, the direction of the elastic cord can be changed, thereby flexibly compressing the stopper 200. In addition, since the tightening column is located at the center of the arc-shaped guide groove, when the guide block slides in the guide groove, the length of the elastic rope remains unchanged, and the pulling force of the sliding block on the tightening column remains unchanged, thereby avoiding excessive pulling force on the tightening column during the sliding process of the sliding block, causing the material blocking member 200 to over-press the scraper 30 and the coating roller 40, and also avoiding the reduction of the pulling force on the tightening column by the sliding block during the sliding process, causing a gap to form between the material blocking member 200 and the scraper 30, and the slurry to flow out of the gap. To secure the position of the sliding block, in one embodiment, the sliding block includes an inner sliding post, a rope winding post, and a fixed post, which are sequentially connected. The rope winding post is used to connect to the elastic rope. The guide groove includes a connected inner sliding groove and a rope winding groove. The inner sliding post is slidably disposed in the inner sliding groove, and the rope winding post is slidably disposed in the rope winding groove. The inner sliding groove and the rope winding groove are connected. The groove wall of the rope winding groove has a sliding hole extending along the path of the sliding groove. The fixed post is inserted into the sliding hole. The side wall of the fixed post is provided with helical meshing teeth for the fixed post. The guide fixing member includes a guide nut, which is threadedly connected to the fixed post and abuts the outer wall of the rope winding groove. By pushing the fixed post extending out of the guide groove, the sliding block moves along the guide groove, and the movement path is circular. When the position of the sliding block is adjusted, the guide nut is rotated to abut the outer wall of the rope winding groove. The width of the inner sliding post is larger than the width of the rope winding groove. The inner sliding post abuts the outer wall of the rope winding groove to prevent the inner sliding post from dislodging from the inner sliding groove.

[0068] To better press the stopper 200 toward the scraper 30 and the coating roller 40, in one embodiment, a tightening post is provided on each side of the stopper 200, and a guide member is provided on each side of the mounting member 100. Each guide member is disposed between a tightening post and the coating roller 40, and elastic cords are connected between the tightening posts and guide blocks on the same side of the stopper 200. To enable pressing the stopper 200 toward the scraper 30 and the coating roller 40 from different directions, the elastic cords on both sides of the stopper 200 further act in different directions. To better press the stopper 200 toward the scraper 30 and the coating roller 40, the elastic cord on one side of the stopper 200 further acts in a direction between the tightening post and the scraper 30, while the elastic cord on the other side of the stopper 200 acts in a direction between the tightening post and the coating roller 40. Since the elastic ropes on both sides of the material blocking member 200 have an action direction component in the direction between the tightening column and the paint port, the elastic ropes on both sides can not only press the material blocking member 200 toward the scraper 30 and the coating roller 40 at the same time, but also press the material blocking member 200 toward the paint port.

[0069] To enable the sliding block to better pull the material stopper 200 toward the scraper 30, in one embodiment, a guide member is connected to the bracket 50. Connecting the guide member to the bracket 50 makes it more stable, allowing the elastic cord to tighten the tightening post, thereby tightening the material stopper 200. Furthermore, one side of the guide member is connected to the mounting member 100, and the other side of the guide member is connected to the bracket 50. To achieve the connection between the guide member and the bracket 50, in one embodiment, the guide member is rotatably connected to a guide adjustment post. The guide adjustment post has a guide adjustment screw hole, and the bracket 50 is provided with a guide adjustment screw. The guide adjustment screw is inserted into the guide adjustment screw hole and is screwed to the side wall of the guide adjustment screw hole. Thus, the connection between the guide adjustment post and the guide adjustment screw can secure the guide member to the bracket 50. Furthermore, by rotating the guide adjustment post, the depth of the guide adjustment screw inserted into the guide adjustment screw hole can be changed, thereby driving the movement of the guide member. Therefore, when the position of the mounting member 100 changes, the guide member can be rotated to move with the mounting member 100.

[0070] To facilitate the placement of the elastic cord, in one embodiment, the rope winding groove has a rope insertion opening on the side facing the tightening post. The elastic cord is inserted through the rope insertion opening and connected to the rope winding post. To facilitate the placement of the elastic cord during the sliding of the sliding block, in one embodiment, the rope insertion opening extends in an arc shape, with the tightening post located at the center of the circle containing the rope insertion opening. To ensure that the sliding block fits the rope winding post, the sliding hole further extends in an arc shape, with the tightening post located at the center of the circle containing the sliding block's extension path.

[0071] See also Figure 6 and Figure 7The present application also provides a coating machine, comprising the material retaining assembly 10 of any of the above-mentioned embodiments. The coating machine further comprises a scraper 30, a coating roller 40, a material plate 20, and a bracket 50. The scraper 30, the coating roller 40, and the material plate 20 are mounted on the bracket 50. A coating port is formed between the scraper 30 and the coating roller 40. At least two material retaining assemblies 10 are mounted on the material plate 20. A material trough is formed between the two mounted assemblies, the scraper 30, the coating roller 40, and the material plate 20, and the material trough is used to place the slurry.

[0072] Compared with the prior art, the present invention has at least the following advantages:

[0073] 1. Since the mounting member and the material stopper can slide relative to each other, the mounting member can be first fixed to the material plate, and then the material stopper can be placed in the mounting groove. By sliding the material stopper in the mounting groove, the material stopper can be closely attached to the coating roller. After the position of the material stopper is adjusted, the position of the material stopper is fixed by the first fixing member. In this way, the material stopper can be closely attached to the coating roller during the coating process.

[0074] 2. By sliding the stopper, the stopper can be close to the scraper to prevent the slurry from flowing out of the gap between the scraper and the stopper.

[0075] 3. By sliding the stopper, the stopper can penetrate into the coating port between the scraper and the coating roller to prevent the slurry from flowing out of the coating port.

[0076] 4. When adjusting the position of the stopper, there is no need to disassemble, install and adjust the installation parts again. It is sufficient to adjust the position of the stopper in the installation groove.

[0077] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
