Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of film covering, and particularly relates to a door plate film covering machine. BACKGROUND

[0002] As a key component in furniture, building decoration and industrial equipment, a door plate is directly exposed to the use environment, and needs to meet the structural support requirement, and also needs to have aesthetic appearance, durability and functionality. Therefore, film covering treatment needs to be performed on the door plate. A door plate film covering machine is a device used for performing film covering treatment on the door plate.

[0003] Generally, the door plate film covering machine comprises a rack, a vacuum adsorption platform and a main machine. The vacuum adsorption platform is movable on the rack. A door plate placing area is arranged on the vacuum adsorption platform. An adsorption hole is arranged on the side of the door plate placing area. An air chamber is arranged in the vacuum adsorption platform and is in communication with the adsorption hole. The air chamber is connected with a negative pressure suction mechanism (such as a vacuum pump). The main machine is used for heating and rolling the film material, so that the film material is attached to the door plate.

[0004] In use, the door plate is first placed on the door plate placing area of the vacuum adsorption platform. Then the film material is covered on the door plate. The edge of the film material is covered on the adsorption hole. The negative pressure suction mechanism is started to work to suck the film material and the air between the film material and the door plate, so that the film material is attached to the door plate. Then the vacuum adsorption platform is moved to send the door plate and the film material into the main machine. The main machine heats the film material and the door plate and rolls the film material, so that the film material is attached to the door plate to complete the film covering of the door plate.

[0005] The problem of the door plate film covering machine in the prior art is that the adsorption holes on the vacuum adsorption platform are often blocked. This is because there are debris in the process of cutting and unwinding the film material. In addition, the glue or adhesive used in the film covering process is prone to overflow in the subsequent rolling process, which may flow into the adsorption hole and solidify. Once the adsorption hole is blocked, the negative pressure distribution is uneven, the film material cannot be effectively sucked, and defects such as air bubbles and wrinkles are prone to occur between the film material and the door plate.

[0006] To solve this problem, the existing technology additionally provides an air compressor in communication with the air chamber. When the machine stops working, the air compressor supplies high-pressure gas into the air chamber to blow back the adsorption hole to flush out the blockage in the adsorption hole. However, in actual use, it is found that because the number of adsorption holes is large and only part of the adsorption holes are blocked in general, the high-pressure gas in the air chamber tends to be sprayed out of the adsorption holes that are not blocked, which reduces the impact force on the blockage (especially the solidified glue or adhesive), and the blockage cannot be flushed out. The effect of back blowing and unblocking is poor. SUMMARY

[0007] The door plate laminating machine provided by the present application solves the technical problem of poor effect of blowback unblocking of the suction holes on the vacuum suction platform in the prior art.

[0008] To solve the above problems, the door plate laminating machine provided by the present application adopts the following technical scheme: a door plate laminating machine, comprising a vacuum suction platform having a gas chamber inside, wherein a suction hole group in communication with the gas chamber is arranged on the top of the vacuum suction platform, and an air port in communication with the gas chamber is further arranged on the vacuum suction platform, and the air port is used for connecting an air compressor; the suction hole group comprises a plurality of suction holes arranged in sequence and spaced apart along the left-right direction; the door plate laminating machine further comprises a plugging mechanism, which comprises a mounting frame slidingly assembled in the gas chamber in front and back directions, and further comprises a plugging block arranged on the mounting frame and corresponding to each suction hole, wherein each plugging block is slidingly assembled on the mounting frame along the left-right direction, and each plugging block has a closed position opposite to the suction hole and an open position opening the suction hole when sliding left and right;

[0009] The plugging mechanism further comprises a driving component for driving the plugging block at the closed position to move left and right to the open position;

[0010] When the air compressor is turned on for blowback, the mounting frame moves forward and backward with each plugging block moving to the closed position, and the driving component drives each plugging block to open the suction hole in sequence and keeps other plugging blocks at the closed position.

[0011] When working normally, the mounting frame drives the plugging block to move to one side of the suction hole in the front and back directions, the suction hole is opened, and the film material can be normally sucked. When the suction hole is blocked, the suction hole needs to be blown back, the mounting frame moves forward and backward, and the plugging block is placed in the closed position, and the plugging block blocks the corresponding suction hole. When the driving component works, the plugging block can be driven to the open position while other plugging blocks are kept at the closed position, that is, only part of the suction holes are opened, the high-pressure gas in the gas chamber is completely sprayed out of the opened suction holes, the gas is more concentrated, the blowback force is greater, the blowback effect is better, and the suction hole can be prevented from being blocked, and the blowback unblocking effect is better.

[0012] As a further improvement, a force block is slidingly assembled on the plugging block, a force block elastic element is arranged on the plugging block and pushes the force block away from the plugging block, and the force block has a force inclined surface;

[0013] The driving component comprises a plugging block elastic element arranged on the mounting frame, and the plugging block elastic element is used for pushing the plugging block to the closed position;

[0014] The driving component further comprises a pushing piece slidingly assembled in the gas chamber, and the pushing piece moves left and right and pushes the force inclined surface of the force block, so that the plugging block moves to the open position against the action of the plugging block elastic element. After the force block moves towards the plugging block, the pushing piece passes over the force block, and the plugging block is reset to the closed position under the action of the plugging block elastic element.

[0015] When the pushing piece moves leftward or rightward, after the pushing piece pushes the force receiving slope of the force receiving block, on one hand, the force receiving block drives the blocking block to move to the opening position against the elastic member of the blocking block, so as to open the corresponding adsorption hole, and the gas in the air chamber can be sprayed out of the adsorption hole to clean the adsorption hole; on the other hand, the force receiving block itself moves towards the blocking block against the elastic member of the force receiving block, so as to avoid the pushing piece, and the pushing piece can continue to move beyond the force receiving block, and after the pushing piece moves beyond the force receiving block, the force receiving block is reset under the action of the elastic member of the force receiving block, and the blocking block is reset to the closed position under the action of the elastic member of the blocking block. Through the movement of the pushing piece, each adsorption hole can be opened in turn, and the adsorption hole is closed after being cleaned.

[0016] As a further improvement, the adsorption hole group has at least two, and the at least two adsorption hole groups are arranged in a front-rear direction interval, and the adsorption holes in each adsorption hole group are located on the same front-rear extending straight line;

[0017] The blocking blocks corresponding to the adsorption holes located on the same front-rear extending straight line are connected together, and at least one of the connected blocking blocks is provided with the force receiving block.

[0018] As a further improvement, the mounting frame includes mounting plates located on the left and right sides, at least two guide rods fixed on the mounting plates at both ends, and each guide rod corresponds to each adsorption hole group one by one;

[0019] The blocking block is slidingly assembled on the guide rod.

[0020] As a further improvement, the pushing piece includes a pushing plate for pushing the force receiving block and a pushing block for pushing the mounting frame, the pushing block is located at the top of the pushing plate, and the pushing block is located on one side of the pushing plate in the front-rear direction, the pushing block is provided with a pushing slope, and the pushing slope is used to push the mounting frame in the left-right direction to place the blocking block in a front-rear opposite state with the adsorption hole; the blocking mechanism further includes a mounting frame elastic member arranged between the mounting frame and the vacuum adsorption platform, and the mounting frame elastic member is used to push the mounting frame to place the blocking block in a front-rear staggered state with the adsorption hole;

[0021] The pushing plate is located below the mounting frame, and the force receiving block is telescopic assembled at the bottom of the blocking block.

[0022] When the pushing block moves leftward or rightward, the pushing slope can push the mounting frame to move forward and backward, that is, the forward and backward movement of the mounting frame and the left and right movement of the blocking block are driven by the pushing piece, and one power source realizes the movement in two mutually perpendicular directions, saves the power source, and reduces the operation cost.

[0023] As a further improvement, the pushing block has the pushing slope on both left and right sides, and the pushing block can push the mounting frame to move in the front-back direction when moving left or right.

[0024] The force receiving block has the force receiving slope on both left and right sides, and the pushing plate can push the force receiving block to move to the opening position when moving left or right.

[0025] The pushing block has the pushing slope on both left and right sides, and the force receiving block has the force receiving slope on both left and right sides, and the pushing block can open and close the blocking block when moving left or right, and the pushing block does not need to return after moving in one direction during back blowing.

[0026] As a further improvement, the door plate laminating machine further comprises a filter screen arranged in the air chamber, and when the film material is adsorbed, the impurities entering the air chamber through the adsorption hole are blocked by the filter screen.

[0027] The bottom of the pushing piece is provided with a scraping part, and the scraping part can scrape the impurities on the filter screen when the pushing piece moves left or right.

[0028] The filter screen can filter the impurities to prevent the impurities from blocking the negative pressure suction mechanism, and the scraping part can scrape the impurities on the filter screen to avoid the filter screen being blocked. When the pushing piece moves left or right, it can not only open and close the adsorption hole, but also scrape the filter screen, and the function is more concentrated.

[0029] As a further improvement, the filter screen is floatingly assembled in the air chamber in the up-down direction, and the blocking mechanism further comprises an elastic supporting piece arranged in the air chamber, the elastic supporting piece being located below the filter screen and upwardly pushing the filter screen.

[0030] The filter screen comprises inclined sections at both left and right ends and a horizontal section in the middle, the inclined sections being inclined downward from the horizontal section; the pushing piece is located above and below the inclined sections when located at both left and right ends of the air chamber, and the pushing piece downwardly pushes the filter screen through the inclined sections when moving in the left-right direction.

[0031] The air port is used for being connected with the negative pressure suction mechanism at the same time; when the film material is adsorbed, the filter screen is located above the air port, and when back blowing, the pushing piece pushes the filter screen to be located below the air port.

[0032] When adsorbing, the filter screen is located above the air port and can filter the impurities; when back blowing, the filter screen is located below the air port, and the high-pressure gas from the air port will not blow back to the filter screen, thereby avoiding the impurities on the filter screen being blown out of the adsorption hole.

[0033] As a further improvement, the air chamber has impurity containing cavities at both left and right ends of the bottom, and the pushing piece is used for scraping the impurities on the filter screen into the impurity containing cavities.

[0034] As a further improvement, the top of the vacuum adsorption platform has a door plate placement area, and the vacuum adsorption platform is provided with the air chamber and the adsorption hole group on both sides of the door plate placement area.

[0035] The beneficial effects are:

[0036] 1. During normal operation, the mounting frame drives the blocking block to move to one side of the front and rear direction of the adsorption hole, the adsorption hole is opened, and the film material can be normally adsorbed. When the adsorption hole is blocked, the adsorption hole needs to be backflushed, the mounting frame moves forward and backward, the blocking block is placed in the closed position, and the blocking block blocks the corresponding adsorption hole. When the driving part works, the blocking block can be driven to the open position while the other blocking blocks remain in the closed position, that is, only part of the adsorption hole is opened, the high-pressure gas in the air chamber is completely sprayed out of the opened adsorption hole, the gas is more concentrated, the backflushing force is greater, the backflushing effect is better, and the adsorption hole can be prevented from being blocked, and the backflushing and unblocking effect is better.

[0037] 2. When the pushing piece moves left and right, after the pushing piece pushes the stress slope of the stress block, on the one hand, the stress block drives the blocking block to move to the open position against the blocking block elastic element, thereby opening the corresponding adsorption hole, and the gas in the air chamber can be sprayed out of the adsorption hole to backflush and clean the adsorption hole; on the other hand, the stress block itself moves towards the blocking block against the stress block elastic element, avoiding the pushing piece, so that the pushing piece can continue to move beyond the stress block, and when the pushing piece moves beyond the stress block, the stress block is reset under the action of the stress block elastic element, and the blocking block is reset to the closed position under the action of the blocking block elastic element. Through the movement of the pushing piece, each adsorption hole can be opened in turn, and the adsorption hole is closed after backflushing.

[0038] 3. When the pushing block moves left and right, the pushing slope can push the mounting frame to move forward and backward, that is, the forward and backward movement of the mounting frame and the left and right movement of the blocking block are driven by the pushing piece, and one power source realizes the movement in two mutually perpendicular directions, saving the power source and reducing the operating cost.

[0039] 4. The two sides of the pushing block are provided with pushing slopes, and the two sides of the stress block are provided with stress slopes, so that the pushing block can open and close the blocking block when moving left and right, and the pushing block does not need to return after moving in one direction during backflushing.

[0040] 5. The filter screen can filter sundries to prevent the negative pressure suction mechanism from being blocked, and the scraping part can scrape off the sundries on the filter screen to prevent the filter screen from being blocked. When the pushing piece moves left and right, it can not only open and close the adsorption hole, but also scrape the filter screen, and the function is more concentrated.

[0041] 6、When adsorbing, the filter screen is above the air port, which can filter sundries; when back blowing, the filter screen is below the air port, the high pressure gas from the air port will not back blow the filter screen, thus avoiding blowing the sundries on the filter screen out of the adsorption hole.

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0070] Embodiments of the door plate film laminating machine provided by the present application:

[0071] AsFigures 1 to 20 As shown, the door panel laminating machine includes a frame 1, a main unit 2, a vacuum adsorption platform 3, a drive mechanism, and a sealing mechanism and a filter structure installed in the vacuum adsorption platform 3.

[0072] like Figures 1 to 14 As shown, the vacuum adsorption platform 3 is slidably mounted on the frame 1 in the left-right direction. The vacuum adsorption platform 3 is used to place door panels and adsorb the membrane material covering the door panels. The top of the vacuum adsorption platform 3 has a door panel placement area 31 for placing door panels. Adsorption holes 33 are opened on the top of the vacuum adsorption platform 3, and there are adsorption holes 33 on both the front and back sides of the door panel placement area 31. The adsorption holes 33 on the same side are arranged in a matrix. Adsorption holes 33 that are located on the same straight line in the left-right direction are defined as an adsorption hole group 32. There are three adsorption hole groups 32 on the front and back sides of the door panel placement area 31, and the adsorption holes 33 of each adsorption hole group 32 are located on the same straight line in the front-back direction.

[0073] A nut block 38 is fixed at the bottom of the vacuum adsorption platform 3, and a threaded hole is opened in the nut block 38 that runs through the left and right sides.

[0074] The vacuum adsorption platform 3 has two air chambers 34 inside, which are arranged at intervals along the front-to-back direction. The two air chambers 34 correspond to the adsorption holes 33 on both sides of the door panel placement area 31, and the air chambers 34 are connected to the adsorption holes 33. The bottom left and right sides of the air chambers 34 are respectively provided with debris receiving cavities 35, which are arranged to protrude in the left-to-right direction. The top of the air chambers 34 is provided with a sliding groove 36 extending in the front-to-back direction.

[0075] The vacuum adsorption platform 3 has an air inlet 37 connected to the air chamber 34. This air inlet 37 is connected to both an external negative pressure suction mechanism to create a negative pressure environment within the air chamber 34 and an external air compressor to create a high-pressure environment within the air chamber 34. Specifically, a main pipe can be connected to the air inlet 37, which is connected to two branch pipes. These branch pipes are respectively connected to the negative pressure suction mechanism and the air compressor, and valves are installed on the branch pipes to control their opening and closing. When membrane material needs to be adsorbed, the negative pressure suction mechanism is activated; when backflushing of the adsorption holes 33 is required, the air compressor is activated.

[0076] The number of sealing mechanisms is equal to and corresponds one-to-one with the number of air chambers 34. The sealing mechanism includes a mounting frame 41, a mounting frame elastic element 42, a fixing plate 46, a sealing block 47, and a driving component.

[0077] The mounting bracket 41 is slidably assembled in the groove 36 of the air chamber 34 in the front-to-back direction. The mounting bracket 41 includes a mounting plate 43, a connecting plate 44, and a guide rod 45. There are two mounting plates 43, which are arranged at intervals in the left-to-right direction. The mounting plates 43 extend back-to-back and are parallel to each other. The mounting plates 43 are in contact with the groove 36. The connecting plate 44 connects the left and right mounting plates 43 and is located at one end of the mounting plate 43 near the middle of the vacuum adsorption platform 3.

[0078] The guide rod 45 extends in the left-right direction, and its left and right ends are fixed to the two mounting plates 43 respectively. There are three guide rods 45, which are parallel to each other and correspond one-to-one with the three adsorption hole groups 32.

[0079] The mounting bracket elastic element 42 is located in the slide groove 36. The mounting bracket elastic element 42 is connected between the mounting plate 43 and the vacuum adsorption platform 3. Here, the mounting bracket elastic element 42 is a compression spring. The mounting bracket elastic element 42 applies an elastic force in the front-back direction to the mounting plate 43, causing the mounting plate 43 to slide toward the middle position of the vacuum adsorption platform 3.

[0080] The number of fixing plates 46 and sealing blocks 47 is equal to the number of adsorption holes 33 and they correspond one-to-one.

[0081] The fixing plate 46 is fixed to the guide rod 45, and in the left-right direction, each fixing plate 46 is located on the same side of the corresponding adsorption hole 33. The sealing block 47 slides on the guide rod 45 in the left-right direction.

[0082] like Figure 18 , Figure 19 As shown, three sealing blocks 47 located on the same straight line in the front-back direction are connected together by connecting rods 49. Specifically, the connecting rods 49 connect two adjacent sealing blocks 47 in the front-back direction.

[0083] Here, three connected sealing blocks 47 are defined as forming a sealing block group. In this group, a force-bearing block 410 is installed at the bottom of the middle sealing block 47. The force-bearing block 410 is telescopically fitted onto the bottom of the sealing block 47, with a pointed bottom end, thus forming force-bearing inclined surfaces 411 on its left and right sides. The force-bearing block 410 and the sealing block 47 are connected by a force-bearing block elastic element 417, which pushes the force-bearing block 410 downwards. This elastic element 417 is typically a compression spring. When the force-bearing inclined surface 411 of the force-bearing block 410 is subjected to a lateral pushing force, the force-bearing block 410 will cause the sealing block 47 to move laterally against the action of the sealing block elastic element 48, and the force-bearing block 410 will also move upwards against the action of the force-bearing block elastic element 417.

[0084] The driving component has the effect of closing each adsorption hole 33 first and then opening each adsorption hole 33 individually in turn when back blowing the adsorption holes 33. The driving component comprises a pushing piece 412, a first driving screw 413, a motor, and a blocking piece elastic element 48.

[0085] The blocking piece elastic element 48 is equal in number to the fixed plate 46 and the blocking piece 47 and corresponds to each of them one by one. The blocking piece elastic element 48 is connected to the fixed plate 46 and the blocking piece 47. When the mounting rack elastic element 42 is in a natural state and the blocking piece elastic element 48 is in a natural state, each blocking piece 47 is located on the same line as the corresponding adsorption hole 33 in the front-rear direction, but is arranged in turn in the front-rear direction, and the blocking piece 47 does not close the adsorption hole 33. After the mounting rack 41 slides against the action of the mounting rack elastic element 42, the blocking piece 47 can be moved to directly below the corresponding adsorption hole 33, thereby closing the corresponding adsorption hole 33.

[0086] The pushing piece 412 is slidably assembled in the air chamber 34 in the left-right direction. The pushing piece 412 comprises a pushing plate 414 and a pushing block 415. The pushing plate 414 is located below the mounting rack 41, and the plate thickness direction of the pushing plate 414 is the left-right direction. The pushing block 415 is fixedly installed on the top of the pushing plate 414 and located on one side of the pushing plate 414 in the front-rear direction, specifically, the side close to the middle position of the vacuum adsorption platform 3. The top of the pushing block 415 is located above the bottom surface of the mounting rack 41, and the pushing block 415 is a triangular block, both sides of which have a pushing inclined surface 416.

[0087] The filtering structure is installed in the air chamber 34 and located below the blocking mechanism. The filtering structure comprises a filter screen 51 and an elastic support.

[0088] The filter screen 51 comprises a horizontal section 52 and inclined sections 53 located on both sides of the horizontal section 52. The inclined sections 53 are inclined downward from the horizontal section 52, and the horizontal section 52 is provided with filter holes.

[0089] The elastic support is fixedly installed at the bottom of the air chamber 34 and connected to the filter screen 51. The elastic support has the effect of upwardly pushing the filter screen 51. Here, the elastic support comprises a first cylinder 54 fixed to the filter screen 51, a second cylinder 55 fixed to the bottom of the air chamber 34, and a spring. The first cylinder 54 is sleeved outside the second cylinder 55, and the spring is connected at the upper end to the filter screen 51 and at the lower end to the bottom of the air chamber 34.

[0090] When the pusher 412 is located at the left and right ends, the pusher 412 and the left and right ends of the filter screen 51 are vertically aligned. The elastic support pushes the filter screen 51 upward, so that the filter screen 51 is located above the air port 37. The gas and impurities entering the air chamber 34 from the adsorption hole 33 will be filtered by the filter screen 51 before the gas enters the air port 37. During backflushing, the pusher 412 moves in the left and right direction. The bottom of the pusher 412 pushes the filter screen 51 downward through the inclined section 53, so that the filter screen 51 descends to below the air port 37. When the pusher 412 moves left and right, its bottom pushes the impurities on the filter screen 51 to the left and right ends of the filter screen 51. The impurities enter the impurity receiving cavities 35 on the left and right sides along the inclined section 53.

[0091] The function of the drive mechanism is to drive the vacuum adsorption platform 3 to move left and right. The drive mechanism includes a second drive screw 61, which is rotatably mounted on the frame 1 around the left and right extending axis. The second drive screw 61 passes through the nut block 38 and is threadedly engaged with the nut block 38. When the second drive screw 61 rotates, it drives the nut block 38 to move left and right.

[0092] It should be noted that, in actual use, a pressure relief valve can be installed on the vacuum adsorption platform 3. The pressure relief valve is connected to the gas chamber 34. When all the adsorption holes 33 are closed, the pressure in the gas chamber 34 continues to rise. When the pressure in the gas chamber 34 reaches the set value, the pressure relief valve opens to release the pressure.

[0093] Usage: During normal operation, the door panel laminating machine is in operation. Figures 2 to 7 In this state, the pusher 412 is located at both ends, and the filter screen 51 is pushed upwards above the air port 37. The mounting bracket 41 and the sealing block 47 are pushed by the elastic element 42 of the mounting bracket to positions arranged sequentially before and after the adsorption hole 33, and the adsorption hole 33 is not sealed. The door panel is placed on the door panel placement area 31, the membrane material is covered on the door panel, the vacuum adsorption mechanism works, and the edge of the membrane material is adsorbed through the adsorption hole 33. Air enters the air chamber 34 through the adsorption hole 33, the filter screen 51 filters the impurities in the gas, and then the air enters the air port 37.

[0094] During backflushing, the motor of the sealing mechanism starts, and the pusher 412 moves left and right; here, we take the pusher 412 moving from right to left as an example. The pusher slope 416 of the pusher block 415 pushes the connecting plate 44 of the mounting bracket 41, and the mounting bracket 41 moves back and forth against the force of the elastic element 42 of the mounting bracket. The sealing block 47 is vertically aligned with the adsorption hole 33, and the sealing block 47 is in the closed position. At the same time, the pusher plate 414 presses down on the filter screen 51, causing the filter screen 51 to descend below the air port 37. The air compressor starts and fills the air chamber 34 with compressed gas.

[0095] When the pushing plate 414 moves to the rightmost row of the blocking blocks 47, the pushing plate 414 pushes the force receiving slope 411 of the force receiving block 410. On one hand, the force receiving block 410 drives the blocking blocks 47 to move leftward, so that the blocking blocks 47 are staggered with the adsorption holes 33, the high-pressure gas in the air chamber 34 is sprayed out of the adsorption holes 33, the sundries in the adsorption holes 33 are blown away, and the blocking blocks 47 are in the open position; on the other hand, the force receiving block 410 moves upward relative to the blocking blocks 47, thereby forming an avoidance for the pushing plate 414. When the pushing plate 414 passes the force receiving block 410, the force receiving block 410 is reset under the action of the force receiving elastic member 417, and the blocking blocks 47 are reset and re-block the adsorption holes 33 under the action of the blocking elastic member 48. Thus, in the process of moving the pushing member 412 from right to left, the adsorption holes 33 are opened and closed in turn, so that the gas is sprayed out of the opened adsorption holes 33 more concentratedly, and the blowback effect is improved.

[0096] In the process of moving the pushing member 412, the bottom of the pushing plate 414 can scrape the sundries on the filter screen 51 and make the sundries enter the sundry containing cavity 35 along the inclined section 53. In the embodiment, the bottom of the pushing plate 414 is used to scrape the sundries on the filter screen 51, and the bottom of the pushing plate 414 constitutes a scraping part.

[0097] In the embodiment, a gas port 37 is opened on the vacuum adsorption platform 3 corresponding to the air chamber 34, and the gas port 37 is connected with the negative pressure suction mechanism and the air compressor at the same time; the filter screen 51 is arranged in a floating up and down manner, and during adsorption, the filter screen 51 is located above the gas port 37, and during blowback, the filter screen 51 is located below the gas port 37. In other embodiments, two gas ports 37 can be arranged corresponding to the air chamber 34, one gas port 37 is connected with the negative pressure suction mechanism and located below the filter screen 51, and the other gas port 37 is connected with the air compressor and located above the filter screen 51.

[0098] In the embodiment, the pushing block 415 is provided with a pushing slope 416, and the pushing block 415 can drive the mounting frame 41 to move forward and backward through the pushing slope 416. In other embodiments, the pushing block 415 can be removed, and structures such as air cylinders and electric push rods can be additionally arranged to drive the mounting frame 41 to move forward and backward, and at this time, the mounting elastic member 42 can be cancelled.

[0099] In the embodiment, the blocking blocks 47 corresponding to the adsorption holes 33 located on the same straight line extending forward and backward are connected together, and one of the blocking blocks 47 is provided with the force receiving block 410. In other embodiments, the force receiving block 410 can be arranged on each of the blocking blocks 47, and at this time, the blocking blocks 47 corresponding to the adsorption holes 33 located on the same straight line extending forward and backward can no longer be connected together.

[0100] In other embodiments, the driving component can include a telescopic member corresponding to each blocking block 47, and the telescopic member is installed on the mounting frame. During back flushing, only one or two adsorption holes 33 are opened at a time, and the other adsorption holes 33 are closed. By sequentially opening each adsorption hole 33, back flushing of all adsorption holes 33 can be achieved.

[0101] In addition, in the description of the present specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise explicitly and specifically limited.
