[0002] Pearl cotton (EPF) is a commonly used packaging material characterized by its lightness, softness, excellent cushioning, and cost-effectiveness. In the production and processing of multi-layer EPE foam, a stamping and bonding device is crucial, used to combine single or multiple layers of EPE foam through pressure and adhesives to create products with specific shapes or structures. However, existing multi-layer EPE foam stamping and bonding devices require manual labor to neatly stack the layers, which is time-consuming, labor-intensive, and prone to errors, impacting both the efficiency and quality of multi-layer EPE foam production.

[0003] Therefore, a punching and bonding device and a processing method for multi-layer pearl cotton production and processing have been developed that can automatically stack pearl cotton neatly together and punch it after a certain amount of pearl cotton has accumulated, thereby improving the production efficiency and quality of the multi-layer pearl cotton. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing multi-layer pearl cotton punching and bonding device, which requires manual stacking of corresponding layers of pearl cotton neatly when punching multi-layer pearl cotton, which is time-consuming, labor-intensive, and prone to errors, thus affecting the production efficiency and quality of the multi-layer pearl cotton, the present invention provides a multi-layer pearl cotton production and processing punching and bonding device and processing method that can automatically stack pearl cotton neatly together and punch the pearl cotton after a certain amount of pearl cotton is accumulated, thereby improving the production efficiency and quality of the multi-layer pearl cotton.

[0005] Technical solution: A stamping and bonding device and processing method for multi-layer pearl cotton production and processing, including a base, a processing table, a feeding mechanism and a pressurizing mechanism. The upper side of the base is connected to the processing table, the processing table is provided with a feeding mechanism capable of conveying pearl cotton, and the base is provided with a pressurizing mechanism capable of pressurizing the pearl cotton.

[0006] Furthermore, the feeding mechanism includes a fixed frame, a motor, a rotating shaft, a belt, an empty shaft, a side fixed table, a straight shaft, a cross material frame, a bracket, a compression spring, a rear plate, a built-in spring, a front block frame and a lock column. The front and rear sides of the left side of the processing table are connected with fixed frames, the rear left side of the rear fixed frame is connected with a motor, the left side of the fixed frame is rotatably connected with a rotating shaft, the motor output shaft is connected to the rotating shaft, the right side of the fixed frame is rotatably connected with an empty shaft, a belt is wound around the empty shaft and the rotating shaft, the right side of the fixed frame is connected to the side fixed table, the side fixed table is rotatably connected with a straight shaft, the right side of the straight shaft is rotatably connected to the processing table, the left and right parts of the straight shaft are connected to the cross material frame, the upper side of the right side of the processing table is connected to the front and rear brackets, the rear plate is slidably connected between the brackets, and the brackets are connected to the rear plate. The spring and the rear plate are slidably connected to the front baffle, and the front and rear parts of the front baffle are connected to the rear plate with built-in springs. The right side of the cross material rack on the right is connected with multiple lock columns, and the front baffle is engaged with the adjacent lock columns. The pearl cotton is placed on the belt, and the motor is started to drive the rotating shaft to rotate, so that the belt and the empty shaft rotate, and the pearl cotton is transported to the right, so that the pearl cotton is moved to the side fixed table and the cross material rack. When the pearl cotton contacts the front baffle, it pushes the front baffle to move to the right, and the built-in spring is squeezed and contracted. At this time, the front baffle is separated from the lock column, and the cross material rack drives the straight shaft to rotate under the action of gravity, so that the pearl cotton falls onto the processing table. After the pearl cotton is separated from the front baffle, the built-in spring rebounds, so that the front baffle is reset and re-engaged with the lock column. Repeat the above operation to stack the pearl cotton on the processing table.

[0007] Furthermore, the pressurizing mechanism includes a hydraulic cylinder, a lifting platform, a pressurizing head, a limit assembly, a straight and oblique block and a mechanical counter. Hydraulic cylinders are connected to the front and rear sides of the right side of the base. A lifting platform is connected between the upper sides of the telescopic ends of the hydraulic cylinders. A pressurizing head is connected to the lower side of the lifting platform. A limit assembly is provided on the pressurizing head. A straight and oblique block is connected to the right side of the middle of the lifting platform. The straight and oblique block is extruded and fitted with the rear plate. Mechanical counters are connected to the lower parts of the hydraulic cylinders. The mechanical counters are connected to adjacent hydraulic cylinders through wires. The straight shafts pass through adjacent mechanical counters. The mechanical counters count the number of rotations of the straight shafts. When the count reaches the specified number, the hydraulic cylinder starts to move the lifting platform downward, so that the pressurizing head punches the pearl cotton, so that the multi-layer pearl cotton material is combined together through pressure and adhesive.

[0008] Furthermore, the limit assembly includes a limit spring and a limit block. The lower sides of the left and right parts of the pressure head are slidingly connected to the limit blocks. There are multiple limit springs connected between the limit blocks and the pressure head. When the lifting platform moves downward, it drives the straight and oblique blocks to move downward, and the straight and oblique blocks push the rear plate to the right. The compression spring is squeezed and contracted to prevent the front frame from blocking the limit block. Then the limit blocks move down and are located on both sides of the pearl cotton. The limit springs make the limit blocks close to the processing table to limit the pearl cotton.

[0009] Furthermore, it also includes a gluing mechanism, which includes a fixed plate, a glue spraying box, a water pump and a sensor. The fixed plates are connected to the sides of the right side of the fixed frame that are away from each other, and the glue spraying box is connected between the sides of the fixed plates that are close to each other. The water pump is connected to the upper front side of the glue spraying box, and the sensors are connected to the fixed plates. The sensors are connected to the water pump through wires, and the material pipe is connected to the water pump. After the sensor senses that the pearl cotton is located under the glue spraying box, the water pump starts, allowing the adhesive to enter the glue spraying box and spray onto the surface of the pearl cotton. After the sensor senses that the pearl cotton is away, the water pump is controlled to shut down.

[0010] Furthermore, it also includes a pushing mechanism, which includes a protrusion, a push arm and a push block. The inner side of the lower left part of the belt is connected to the front and rear protrusions. The front and rear sides of the processing table are slidably connected with push arms, and the push arms are squeezed together with the protrusions. The inside of the processing table is slidably connected with a push block, and the push arms are connected to the push blocks. When the belt rotates, it drives the protrusion to move. After the protrusion moves to the push arm, it pushes the push arm to move to the right, so that the push block moves to the right and pushes the multi-layer pearl cotton that has been stamped to move to the right and leave the workbench.

[0011] Furthermore, it also includes a centering mechanism, which includes side columns, a centering plate and a bidirectional screw rod. The left and middle sides of the fixed frame are connected to side columns that are away from each other. The two side columns on the same side are slidably connected to the centering plate. The middle parts of the centering plates are threadedly connected with a bidirectional screw rod. According to the size of the pearl cotton, the bidirectional screw rod is rotated to make the centering plates approach each other along the side columns, so that the pearl cotton passes between the centering plates during transportation.

[0012] Furthermore, crank handles are provided on both the front and rear sides of the bidirectional screw rod.

[0013] Furthermore, it also includes a cleaning mechanism, which includes a mounting plate and a brush. The upper left side of the fixing frame is connected to the mounting plate, and the brushes are connected between the mounting plates. After the pearl cotton is transported to the brush, the brush cleans the surface of the pearl cotton.

[0014] Furthermore, the method includes the following steps:

[0015] S1: Place the EPE on the belt, start the motor, drive the shaft to rotate, make the belt and the empty shaft rotate, transport the EPE to the right, and move the EPE to the side fixed table and the cross material rack. When the EPE contacts the front baffle, it pushes the front baffle to the right, and the built-in spring is squeezed and contracted. At this time, the front baffle is separated from the lock column, and the cross material rack drives the straight shaft to rotate under the action of gravity, causing the EPE to fall onto the processing table.

[0016] S2: When the count reaches the specified number, the hydraulic cylinder starts to move the lifting platform downward, so that the pressure head can punch the pearl cotton;

[0017] S3: When the belt rotates, it drives the convex block to move. After the convex block moves to the push arm, it pushes the push arm to the right, causing the push block to move to the right and push the multi-layer pearl cotton that has been stamped to move to the right and leave the workbench.

[0018] The present invention has the following advantages: 1. After the pearl cotton contacts the front baffle, the front baffle is pushed to the right, and the built-in spring is squeezed and contracted. At this time, the front baffle is separated from the lock column, and the cross material rack drives the straight axis to rotate under the action of gravity, so that the pearl cotton falls onto the processing table, achieving the effect of automatically stacking the pearl cotton neatly together and improving the production efficiency and quality of multi-layer pearl cotton.

[0019] 2. The present invention counts the number of revolutions of the straight shaft by a mechanical counter. When the number is counted to a specified number, the hydraulic cylinder is started to move the lifting platform downward, driving the straight and inclined blocks to move downward, so that the pressure head punches the pearl cotton, thereby achieving the effect of being able to punch the pearl cotton after a certain amount of pearl cotton accumulates, thereby improving the production efficiency and quality of multi-layer pearl cotton.

[0020] 3. The present invention connects the material pipe with the water pump. When the sensor senses that the pearl cotton is located under the spray box, the water pump is started, so that the adhesive enters the spray box and is sprayed onto the surface of the pearl cotton. When the sensor senses that the pearl cotton is moving away, the water pump is controlled to be closed, thereby achieving the effect of automatically gluing the pearl cotton, saving manpower, and improving the production efficiency of the pearl cotton.

[0021] 4. When the belt rotates, the present invention drives the convex block to move. After the convex block moves to the push arm, it pushes the push arm to move to the right, so that the push block moves to the right and pushes the multi-layer pearl cotton that has been stamped to move to the right and away from the workbench, thereby achieving the effect of automatically pushing the material out, saving manpower, and improving the production efficiency of the multi-layer pearl cotton.

[0022] 5. The present invention rotates the bidirectional screw according to the size of the pearl cotton, so that the centering plates are close to each other along the side columns, so that the pearl cotton passes between the centering plates during transportation, thereby achieving the effect of locating the pearl cotton in the center and avoiding the deviation of the pearl cotton.

[0023] 6. After the pearl cotton is transported to the scrubbing brush, the scrubbing brush cleans the surface of the pearl cotton, thereby achieving the effect of improving the bonding quality of the pearl cotton. BRIEF DESCRIPTION OF THE DRAWINGS

The front and rear sides of the left part of the processing table 2 are connected to the fixed frame 31, the rear side of the left part of the fixed frame 31 is connected to the motor 32, the rotating shaft 33 is rotatably connected between the left part of the fixed frame 31, the output shaft of the motor 32 is connected to the rotating shaft 33, the empty shaft 35 is rotatably connected between the right part of the fixed frame 31, the belt 34 is wound around the empty shaft 35 and the rotating shaft 33, and the right side of the fixed frame 31 is connected There is a side fixed table 36, and the side fixed table 36 is rotatably connected to a straight shaft 37. The right side of the straight shaft 37 is rotatably connected to the processing table 2, and the left and right parts of the straight shaft 37 are connected to a cross material rack 38. The upper right side of the processing table 2 is connected to two front and rear brackets 39, and a rear plate 310 is slidably connected between the brackets 39. Compression springs 391 are connected between the brackets 39 and the rear plate 310. A front baffle 312 is slidably connected to the rear plate 310, and the front and rear parts of the front baffle 312 are connected to the rear plate 310 with built-in springs 311. Four lock columns 313 are connected to the right side of the cross material rack 38 on the right side, and the front baffle 312 is snap-fitted with the adjacent lock columns 313.

[0037] like Figure 1 and Figure 5 As shown, the pressurizing mechanism 4 includes a hydraulic cylinder 41, a lifting platform 42, a pressurizing head 43, a limit assembly, a straight and oblique block 46 and a mechanical counter 47. The front and rear sides of the right part of the base 1 are connected with the hydraulic cylinder 41. The lifting platform 42 is connected between the upper side of the telescopic end of the hydraulic cylinder 41, and the lower side of the lifting platform 42 is connected to the pressurizing head 43. A limit assembly is provided on the pressurizing head 43. The limit assembly includes a limit spring 44 and a limit block 45. The lower sides of the left and right parts of the pressurizing head 43 are both slidably connected to the limit block 45. Four limit springs 44 are connected between the limit block 45 and the pressurizing head 43. A straight and oblique block 46 is connected to the right side of the middle of the lifting platform 42. The straight and oblique block 46 is squeezed and fitted with the rear plate 310. The lower part of the hydraulic cylinder 41 is connected with a mechanical counter 47. The mechanical counters 47 are connected to adjacent hydraulic cylinders 41 through wires, and the straight shafts 37 pass through adjacent mechanical counters 47.

[0038] After the cam 312 is released, the rear frame 313 is pushed back and the rear frame 314 is pushed down, and the rear frame 315 is pushed back and the rear frame 316 is pushed down, so that the cam 312 is pushed back and the rear frame 317 is pushed down, and the rear frame 318 is pushed back and the rear frame 319 is pushed back. The above operation is repeated, and the EPE foam is stacked and placed on the processing table 2. The mechanical counter 47 counts the number of revolutions of the straight shaft 37. When the EPE foam is transported, the adhesive is applied to the surface of the EPE foam.

This automatically stacks the EPE foam neatly together and can press the EPE foam after a certain amount of EPE foam is accumulated, thereby improving the production efficiency and quality of the multi-layer EPE foam. After the pressing is completed, the lifting platform 42 is reset, and the compression spring 391 rebounds, causing the rear plate 310 to return to its original position.

The water pump 53 is connected to the upper front side of the glue spraying box 52, and the fixed plates 51 are connected to the sensors 54. The sensors 54 are connected to the water pump 53 through wires.

[0040] The gluing mechanism 5 of the present device can be used to automatically gluing the pearl cotton. The material pipe is connected to the water pump 53. After the sensor 54 senses that the pearl cotton is located below the glue spraying box 52, the water pump 53 is started, so that the adhesive enters the glue spraying box 52 and is sprayed onto the surface of the pearl cotton. After the sensor 54 senses that the pearl cotton is moving away, the water pump 53 is controlled to be closed, thereby automatically gluing the pearl cotton, saving manpower and improving the production efficiency of the pearl cotton.

[0041] like Figure 1 and Figure 8 As shown, it also includes a pushing mechanism 6, which includes a protrusion 61, a pushing arm 62 and a pushing block 63. The inner side of the lower left part of the belt 34 is connected to the front and rear protrusions 61, and the front and rear sides of the processing table 2 are slidably connected to the pushing arms 62. The pushing arms 62 are squeezed and fitted with the protrusions 61.

[0043] like Figure 1 and Figure 9 As shown, a centering mechanism 7 is also included, and the centering mechanism 7 includes a side column 71, a centering plate 72 and a bidirectional screw rod 73. The side columns 71 are connected to the left and middle sides of the fixed frame 31 that are away from each other.

The bidirectional screw rod 73 is provided with a crank handle on both the front and rear sides for easy grasping and rotation.

[0044] By using the centering mechanism 7 of the present device, the pearl cotton can be located in the center position. According to the size of the pearl cotton, the bidirectional screw rod 73 is rotated to make the centering plates 72 approach each other along the side columns 71, so that the pearl cotton passes between the centering plates 72 during transportation, thereby playing the role of being able to center the pearl cotton and avoiding the pearl cotton from being offset.

[0045] like Figure 1 and Figure 9 As shown, a dust cleaning mechanism 8 is also included. The dust cleaning mechanism 8 includes a mounting plate 81 and a scrub brush 82 .
