Description

Technical Field

[0001] The present invention belongs to the technical field of packaging equipment, and particularly relates to an EPE cotton pasting mechanism of an automatic winding machine. Background Art

[0002] With the development of industrial technology, the daily operation of the packaging industry has changed from manual labor to mechanization. The cotton pasting mechanism is one of the mechanisms in the automatic winding machine, responsible for realizing the functions of feeding, cutting, forming, and pasting the packaging material EPE cotton. In the traditional cotton pasting mechanism, a roller feeding structure is adopted, and the EPE cotton is in line contact transmission during the feeding process. Since the surface of the EPE cotton material itself is not uniform in thickness, using roller transmission easily leads to the problem of uneven cotton feeding.

[0003] Therefore, the existing technology needs to be improved and developed. Summary of the Invention

[0004] The purpose of this application is to provide an EPE cotton pasting mechanism of an automatic winding machine, which can realize the stable and uniform transportation of EPE cotton.

[0005] An EPE cotton pasting mechanism of an automatic winding machine provided by this application, the cotton pasting mechanism includes a mounting frame, and a cotton feeding structure arranged on the mounting frame. The cotton feeding structure is arranged between the cotton placing tray and the cotton cutting structure for transporting EPE cotton. The cotton feeding structure includes a rotating roller, a power component, and a conveyor belt;

[0006] The rotating roller is vertically fixed on the mounting frame. There are two groups of rotating rollers, and the two groups of rotating rollers are arranged opposite to each other at an interval of a first distance. The first distance extends in the direction from the cotton placing tray to the cotton cutting structure, and the EPE cotton is transmitted in the first distance;

[0007] The power component is connected to the rotating roller to drive the rotating roller to rotate;

[0008] There are two conveyor belts, which are respectively wound around the two groups of rotating rollers and are in close contact with the EPE cotton in the first distance. Driven by the rotating roller, the EPE cotton is transported from the position where the cotton placing tray is located to the position where the cotton cutting structure is located.

[0009] The EPE cotton pasting mechanism of an automatic winding machine provided by this application. The pasting mechanism includes a mounting frame and a cotton feeding structure arranged on the mounting frame. The cotton feeding structure is arranged between a cotton placing disc and a cotton cutting structure. The EPE is wound on the cotton placing disc, and the free end of the EPE is released from the cotton placing disc, connected to the cotton feeding structure, and transported through the cotton feeding structure to the position where the cotton cutting structure is located. When the EPE transported by the cotton feeding structure reaches the set size, the cotton cutting structure cuts off the EPE. Among them, the cotton feeding structure includes a rotating roller, a power component and a conveyor belt. The rotating roller is vertically fixed on the mounting frame. There are two groups of rotating rollers, so that the EPE released from the cotton placing disc passes through the rotating rollers of the cotton feeding structure and runs in the direction of the cotton cutting structure. The two groups of rotating rollers are arranged opposite to each other at a first distance. The first distance extends in the direction from the cotton placing disc to the cotton cutting structure. The EPE passes through the first distance. The two groups of relatively arranged rotating rollers limit the displacement of the EPE from both sides, so that the EPE can run close to the rollers, avoiding the displacement of the EPE during the process of being transported from the cotton placing disc to the position where the cotton cutting structure is located. The power component is connected to the rotating roller and drives the rotating roller to rotate. When the rotating roller rotates, it can push the EPE in close contact with it to move, so that the EPE can be smoothly transported. There are two conveyor belts, which are respectively wound on the two groups of rotating rollers and are in close contact with the EPE in the first distance. When the EPE is transported, there are contact surfaces on both sides to limit it. And the conveyor belt is wound on the rotating roller and can rotate around the roller as the roller rotates. There is a contact surface in close contact on both sides between the conveyor belt and the EPE. Even if the surface of the EPE is uneven, it can still clamp the EPE under the close contact of the conveyor belt and send it to the cotton cutting structure evenly and stably. Therefore, the EPE cotton pasting mechanism of an automatic winding machine proposed by this application has the beneficial effect of being able to transport the EPE evenly and stably.

[0010] Furthermore, the cotton feeding structure also includes a cotton inlet and a cotton outlet. The cotton inlet is arranged on one side of the cotton placing disc and is used to receive the EPE released from the cotton placing disc. The cotton outlet is arranged on one side of the cotton cutting structure and is used to transport the EPE to the cotton cutting structure for cutting.

[0011] By arranging a cotton inlet and a cotton outlet on the cotton feeding structure, it is beneficial to guide the EPE to smoothly enter the first distance for transportation. The cotton inlet is arranged on the side close to the cotton placing disc and is used to guide the EPE into the first distance. The cotton outlet is arranged on the side close to the cotton cutting structure and is used to guide the EPE to output from the first distance.

[0012] Furthermore, a cotton outlet nozzle is arranged on the cotton outlet, and the cotton outlet nozzle extends in the direction of the cotton cutting structure.

[0013] By providing a cotton outlet nozzle at the cotton outlet, and the cotton outlet nozzle extending in the direction towards the cotton cutting structure, during the distance that the EPE foam travels from the cotton outlet to the cotton cutting structure, there is still a component (i.e., the cotton outlet nozzle) to limit the EPE foam, enabling the EPE foam to remain stable and reach the position of the cotton cutting structure without deviation, facilitating the cotton cutting structure to smoothly cut out EPE foam with regular shapes.

[0014] Furthermore, the cotton outlet nozzle at least includes a first limiting piece and a second limiting piece. A second spacing is provided between the first limiting piece and the second limiting piece, and the second spacing communicates with the first spacing. The second spacing is used for conveying the EPE foam.

[0015] By providing the first limiting piece and the second limiting piece, and a second spacing is provided between the first limiting piece and the second limiting piece, after the EPE foam is discharged from the cotton outlet, it naturally enters the second spacing. The first limiting piece and the second limiting piece are in close contact with the EPE foam, enabling the EPE foam to still maintain a uniform and stable state and travel to the position of the cotton cutting structure after being output from the first spacing.

[0016] Furthermore, a T-shaped fixing member is provided in the second spacing. The T-shaped fixing member is connected to the fixing plate at the top of the rotating roller. A fixing through hole is provided on the T-shaped fixing member. The first limiting piece and the second limiting piece are respectively arranged on both sides of the T-shaped fixing member. The first limiting piece and the second limiting piece are fixed to the T-shaped fixing member by using bolts to pass through the first limiting piece, the fixing through hole, and the second limiting piece.

[0017] Furthermore, the cotton cutting structure is arranged on the mounting frame, including a movable frame, a heating wire vertically fixed on the movable frame, and a first driving part connected to the movable frame. The first driving part drives the movable frame to reciprocate in a direction perpendicular to the conveying direction of the EPE foam, driving the heating wire to cut the EPE foam.

[0018] Furthermore, a cotton adhering structure is provided on the side of the cotton cutting structure opposite to the cotton feeding structure. The cotton adhering structure is used for adsorbing the EPE foam cut by the cotton cutting structure onto the surface of the material.

[0019] Furthermore, the cotton adhering structure is arranged on the mounting frame, including a material pressing part, a second driving part, and a third driving part. The third driving part is connected to the second driving part, and the material pressing part is connected to the third driving part, respectively driving the material pressing part to move in the direction from the cotton adhering structure towards the material and in the direction parallel to the material.

[0020] Furthermore, a vacuum adsorption component is slidably arranged on the material pressing part. The vacuum adsorption component includes an adsorption pipe, an adsorption sticker arranged at the end of the adsorption pipe, and a spring sleeved on the adsorption pipe. An air extraction device is connected to the adsorption pipe. The adsorption sticker is communicated with the adsorption pipe for adsorbing the EPE. One end of the spring is connected to the adsorption sticker, and the other end is connected to the connecting plate for fixing the vacuum adsorption component on the material pressing part. When the adsorption sticker adsorbs the EPE on the material and the material pushes the vacuum adsorption component to move towards the cotton pasting structure, the spring plays a buffering role.

[0021] Furthermore, the cotton pasting mechanism is arranged on an automatic winding machine. A fourth driving part is arranged on the lower surface of the mounting frame of the cotton pasting mechanism and is used for driving the cotton pasting mechanism to make a lifting movement on the automatic winding machine.

[0022] As can be seen from the above, a cotton pasting mechanism for an EPE of an automatic winding machine provided by the present application includes a mounting frame and a cotton feeding structure arranged on the mounting frame. The cotton feeding structure is arranged between a cotton placing disc and a cotton cutting structure. The EPE is wound on the cotton placing disc, and the free end of the EPE is released from the cotton placing disc, connected to the cotton feeding structure, and transported to the position where the cotton cutting structure is located through the transportation of the cotton feeding structure. When the EPE conveyed by the cotton feeding structure reaches a set size, the cotton cutting structure cuts off the EPE. Among them, the cotton feeding structure includes rotating rollers, a power component, and a conveyor belt. The rotating rollers are vertically fixed on the mounting frame and are arranged in two groups along the direction from the cotton placing disc to the cotton cutting structure, so that the EPE released from the cotton placing disc passes through the rotating rollers of the cotton feeding structure and runs towards the cotton cutting structure. The two groups of rotating rollers are arranged opposite to each other at a first distance interval, and the EPE passes through the first distance. The two groups of relatively arranged rotating rollers limit the displacement of the EPE from both sides, so that the EPE can fit the setting direction of the rollers and be transported from the cotton placing disc to the position where the cotton cutting structure is located; the power component is connected to the rotating rollers and drives the rotating rollers to rotate. When the rotating rollers rotate, they can push the EPE in close contact with them to move, so that the EPE can be smoothly conveyed; there are two conveyor belts, which are respectively wound on the two groups of rotating rollers and are in close contact with the EPE in the first distance, so that when the EPE is conveyed, there are contact surfaces for limiting it on both sides, and the conveyor belts are wound on the rotating rollers and can rotate around the rollers as the rollers rotate. There is a contact surface where the conveyor belts are in close contact with the EPE on both sides. Even if the surface of the EPE is uneven, the EPE can still be clamped by the close contact of the conveyor belts and be sent to the cotton cutting structure evenly and stably. Therefore, the cotton pasting mechanism for an EPE of an automatic winding machine proposed by the present application has the beneficial effect of being able to convey the EPE evenly and stably.

[0023] Other features and advantages of the present application will be described in the subsequent description, and part of them will become obvious from the description, or be understood by implementing the embodiments of the present application.

[0032] The following details the embodiments of the present invention. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0033] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between various embodiments and / or settings discussed.

[0034] As Figure 1 shown, in the existing technology, the cotton pasting mechanism 3 is arranged on the automatic winding machine 1, and includes a cotton feeding structure, a cotton cutting structure and a cotton pasting structure. The cotton feeding structure includes two rotating rollers, and the two rotating rollers are driven to rotate by a power component. The EPE is discharged from the cotton placing tray, passes through the space between the two rotating rollers, and goes to the cotton cutting structure for cutting. The cotton cutting structure and the cotton pasting structure are fixed on the same movable frame, and the movable frame is connected by a cylinder and pushed in the direction of the material 4. During the process of pushing the movable frame, the cotton cutting structure will contact the EPE earlier than the cotton pasting structure, cut the EPE, and then the cut EPE is driven by the cotton pasting structure to be pasted on the surface of the material 4. In this method, the biggest problem is that the contact between the cotton feeding structure and the EPE is line contact transmission. Due to the manufacturing process limitations of the EPE, there are uneven areas on the surface of the EPE itself. Therefore, in the actual transmission process, the line contact transmission method will cause great transmission instability, and the EPE often skews and offsets, resulting in the EPE finally cut and pasted on the surface of the material 4 not meeting the process requirements. To solve this problem, the present application proposes a cotton pasting mechanism 3 for an automatic winding machine 1.

[0035] As Figure 2 shown, a cotton pasting mechanism 3 for an automatic winding machine 1 proposed by the present application, the cotton pasting mechanism 3 includes a mounting frame 31, and a cotton feeding structure 32 arranged on the mounting frame 31. The cotton feeding structure 32 is arranged between the cotton placing tray 35 and the cotton cutting structure 33 for conveying the EPE. The cotton feeding structure 32 includes a rotating roller 321, a power component 322 and a conveyor belt 333;

[0036] The rotating roller 321 is vertically fixed on the mounting frame 31. There are two groups of rotating rollers 321, and the two groups of rotating rollers 321 are arranged opposite to each other at a first distance 320. The first distance 320 extends in the direction from the cotton placing tray 35 to the cotton cutting structure 33, and the EPE is transmitted in the first distance 320;

[0037] The power component 322 is connected to the rotating roller 321 to drive the rotating roller 321 to rotate;

[0038] There are two conveyor belts 333, which are respectively wound around two sets of rotating rollers 321 and are in close contact with the EPE foam in the first spacing 320. Driven by the rotating rollers 321, the EPE foam is conveyed from the position where the foam-releasing tray 35 is located to the position where the cotton-cutting structure 33 is located.

[0039] In a specific application, the automatic winding machine 1 includes a machine frame 100, a film-winding mechanism 2, a cotton-pasting mechanism 3 and a material conveying mechanism arranged above the machine frame 100. The film-winding mechanism 2 and the cotton-pasting mechanism 3 are arranged opposite to each other, and the material conveying mechanism is arranged on the sides of the film-winding mechanism 2 and the cotton-pasting mechanism 3. The material conveying mechanism conveys the material 4 to the space between the film-winding mechanism 2 and the cotton-pasting mechanism 3. Then, the cotton-pasting mechanism 3 pastes the EPE foam on the surface of the material 4, and the film-winding mechanism 2 winds the EPE foam around the surface of the material 4 to complete the packaging of the material 4. Among them, in order to smoothly complete the packaging process and avoid interference between components, the foam-releasing tray 35, the cotton-feeding structure 32, the cotton-cutting structure 33 and the cotton-pasting structure 34 in the cotton-pasting mechanism 3 are horizontally arranged on one side of the material 4, and the cotton-pasting structure 34 is arranged adjacent to the material 4 to facilitate pasting the EPE foam on the material 4. Among them, for the stability of the installation of the cotton-pasting structure 34, the cotton-pasting structure 34 is provided with a mounting frame 31. The cotton-feeding structure 32, the cotton-cutting structure 33 and the cotton-pasting structure 34 are all fixed on the mounting frame 31 and are fixed on the machine frame 100 of the automatic winding machine 1 through the mounting frame 31, which can not only ensure the integrity of the whole cotton-pasting mechanism 3 but also avoid interference with the components on the machine frame 100 for realizing other functions.

[0040] Among them, in a specific application, as Figure 3 shown, in order to solve the problem of unstable linear contact conveying of the EPE foam, the cotton-feeding structure 32 in the present application includes rotating rollers 321, a power component 322 and conveyor belts 333; the rotating rollers 321 are used for rotating and conveying the EPE foam. Therefore, the rotating rollers 321 need to be vertically fixed on the mounting frame 31 and are arranged in the direction from the foam-releasing tray 35 to the cotton-cutting structure 33 to facilitate guiding the EPE foam to the position where the cotton-cutting structure 33 is located; there are two sets of rotating rollers 321, and the two sets of rotating rollers 321 are arranged opposite to each other, with a first spacing 320 formed in the middle. When the EPE foam passes through the first spacing 320, the rotating rollers 321 on both sides can play a role in restricting the displacement and guiding the forward movement of the EPE foam in the middle. In some preferred embodiments, in order to ensure the stability of the installation of the rotating rollers 321, a fixing plate 337 can be arranged on the top of the rotating rollers 321 to fix the two sets of rotating rollers 321 to avoid deformation or inclination of the rotating rollers 321 due to external impact or other reasons during actual operation, which is not conducive to the conveying of the EPE foam. At the same time, columns 338 can be arranged below the fixing plate 337. The columns 338 are arranged parallel to the rotating rollers 321 and are fixed on the mounting frame 31 to assist in supporting the stability of the installation of the rotating rollers 321.

[0041] In a specific application, the power component 322 is connected to the rotating roller 321 to drive the rotating roller 321 to rotate. In some preferred embodiments, in order to avoid interference between the power component 322 and various structures arranged on the upper surface of the mounting frame 31, the power component 322 can be arranged on the lower surface of the mounting frame 31, wherein the power component 322 can be a servo motor.

[0042] In a specific application, two conveyor belts 333 are provided, each wound around two sets of rotating rollers 321, closely adhering to the EPP in the first spacing 320. In practice, each set of rotating rollers 321 is provided with at least two, spaced apart in the direction from the cotton placing disc 35 to the cotton cutting structure 33. When the conveyor belt 333 is wound around it, the rotating rollers 321 at both ends can stretch the conveyor belt 333 to form a transmission structure that rotates around the rotating rollers 321. Driven by the rotating rollers 321, the conveyor belt 333 moves closely against the EPP, transporting the EPP from the cotton placing disc 35 to the cotton cutting structure 33. During this process, because the conveyor belt 333 has a large contact area with the EPP, even if the surface of the EPP is uneven, the wide-area clamping contact of the conveyor belt 333 can still stably discharge the EPP from the first spacing 320, allowing the cotton cutting structure 33 to cut the EPP into uniform shapes for the cotton attaching structure 34 to adsorb on the surface of the material 4.

[0043] In some preferred embodiments, the cotton feeding structure 32 also includes a cotton inlet 334 and a cotton outlet 335. The cotton inlet 334 is arranged on one side of the cotton tray 35, and the cotton inlet 334 is used to receive the pearl cotton released from the cotton tray 35. The cotton outlet 335 is arranged on one side of the cotton cutting structure 33, and the cotton outlet 335 is used to transport the pearl cotton to the cotton cutting structure 33 for cutting.

[0044] In a specific application, in order to better guide the pearl cotton into the first spacing 320 and be discharged from the first spacing 320 , a cotton inlet 334 and a cotton outlet 335 may be provided on the cotton feeding structure 32 .

[0045] In some preferred embodiments, a cotton outlet nozzle 336 is provided on the cotton outlet 335 , and the cotton outlet nozzle 336 extends toward the cotton cutting structure 33 .

[0046] In a specific application, the cotton feeding structure 32 and the cotton cutting structure 33 are separated by a certain distance. After the EPE foam is discharged from the cotton feeding structure 32, it will run towards the cotton cutting structure 33 without a support. Therefore, there are problems such as insufficient conveying power and easy skewing of the EPE foam in this distance section. To solve the above problems, a cotton outlet nozzle 336 can be provided at the cotton outlet 335, and the cotton outlet nozzle 336 extends in the direction towards the cotton cutting structure 33 to guide the EPE foam to stably move to the position where the cotton cutting structure 33 is located.

[0047] In some preferred embodiments, the cotton outlet nozzle 336 at least includes a first limiting piece 3361 and a second limiting piece 3362. A second spacing 3363 is provided between the first limiting piece 3361 and the second limiting piece 3362, and the second spacing 3363 communicates with the first spacing 320. The second spacing 3363 is used to convey the EPE foam.

[0048] In a specific application, such as Figure 3 , Figure 4 As shown, the cotton outlet nozzle 336 is used to guide the EPE foam to maintain a stable operation to the cotton cutting structure 33 after being discharged from the first spacing 320. Therefore, a first limiting piece 3361 and a second limiting piece 3362 can be provided in the cotton outlet nozzle 336. A second spacing 3363 is provided between the first limiting piece 3361 and the second limiting piece 3362. The second spacing 3363 is used to guide the EPE foam discharged from the first spacing 320 to the cotton cutting structure 33. Therefore, the second spacing 3363 and the first spacing 320 are connected and arranged. In some preferred embodiments, in order to make the EPE foam better maintain a stable and uniform conveyance, the size of the second spacing 3363 can be made equal to the size of the first spacing 320.

[0049] In some preferred embodiments, a T-shaped fixing piece 3364 is provided in the second spacing 3363. The T-shaped fixing piece 3364 is connected to the fixing plate 337 at the top of the rotating roller 321. A fixing through hole 3365 is provided on the T-shaped fixing piece 3364. The first limiting piece 3361 and the second limiting piece 3362 are respectively arranged on both sides of the T-shaped fixing piece 3364. The first limiting piece 3361 and the second limiting piece 3362 are fixed on the T-shaped fixing piece 3364 by using bolts to pass through the first limiting piece 3361, the fixing through hole 3365 and the second limiting piece 3362.

[0050] In a specific application, T-shaped fixing members 3364 are provided at the upper and lower ends of the second spacing 3363. The T-shaped fixing members 3364 are used to fix the first limiting piece 3361 and the second limiting piece 3362 together. Therefore, fixing through-holes 3365 can be provided on the T-shaped fixing members 3364. The first limiting piece 3361 and the second limiting piece 3362 are located on both sides of the T-shaped fixing member 3364. For the stability of fixation, perforations are provided on the first limiting piece 3361 and the second limiting piece 3362 corresponding to the fixing through-holes 3365. After the bolt passes through the perforations on the first limiting piece 3361 and the second limiting piece 3362, and the fixing through-holes 3365 provided on the middle T-shaped fixing member 3364, a nut is used to fix the three together, so that the first limiting piece 3361 and the second limiting piece 3362 can be stably fixed. In a specific embodiment, since both the first limiting piece 3361 and the second limiting piece 3362 are plate-like structures made of metal materials, and in order to lighten the volume of the cotton outlet nozzle 336, both the first limiting piece 3361 and the second limiting piece 3362 are metal sheets, which are easily deformed by external interference, resulting in the deformation of the structure of the cotton outlet nozzle 336 and affecting the stable transportation of the EPE. To solve this problem, a first extension portion 3366 parallel to the extending direction of the cotton outlet nozzle 336 can be provided on one side of the T-shaped fixing member 3364 close to the first limiting piece 3361 and the second limiting piece 3362. The first extension portion 3366 is arranged between the first limiting piece 3361 and the second limiting piece 3362 to ensure that the first limiting piece 3361 and the second limiting piece 3362 can still maintain the stability of the structure when the equipment malfunctions, thereby ensuring the stability of the EPE transportation; the T-shaped fixing member 3364 is also connected to a fixing plate 337 at the top of the rotating roller 321. In order to better fix the T-shaped fixing member 3364 on the fixing plate 337, a second extension portion 3367 parallel to the setting direction of the rotating roller 321 is provided at the upper end of the T-shaped fixing member 3364. The second extension portion 3367 is closely attached to the fixing plate 337 and fixed by bolts. Among them, the fixing plate 337 is a structure for ensuring the installation stability of the rotating roller 321, and the rotating roller 321 and the fixing plate 337 are fixed by bolts. In order to ensure that the rotating roller 321 can still rotate smoothly under the fixation of the fixing plate 337, a certain gap is provided between the fixing plate 337 and the rotating roller 321. Through the cooperation between the above structures, the stability of the EPE transportation can be effectively ensured.

[0051] In some preferred embodiments, the cotton cutting structure 33 is arranged on the mounting frame 31, including a movable frame 330, a heating wire 331 vertically fixed on the movable frame 330, and a first driving portion 332 connected to the movable frame 330. The first driving portion 332 drives the movable frame 330 to reciprocate in a direction perpendicular to the EPE transportation direction, driving the heating wire 331 to cut the EPE.

[0052] In a specific application, such as Figure 5 , Figure 6 shown, the cotton cutting structure 33 is arranged on the side of the cotton outlet nozzle 336 of the cotton feeding structure 32. After the EPE foam is output from the cotton feeding structure 32 with a preset size, the first driving part 332 drives the movable frame 330 to operate, driving the heating wire 331 to cut the EPE foam. During this process, in order to ensure that the heating wire 331 accurately cuts the EPE foam with a preset size, a sensor can be arranged near the cotton outlet nozzle 336 of the cotton feeding structure 32 to monitor the size of the discharged EPE foam in real time. When the set size is reached, the first driving part 332 is immediately controlled to drive the movable frame 330 and the heating wire 331 on the movable frame 330 to operate and cut the EPE foam.

[0053] Among them, in the prior art, the commonly used cotton cutting method is usually straight push cotton cutting. Specifically: the heating wire 331 is arranged on one side of the cotton adhering structure 34 and is closer to the material 4 compared to the cotton adhering structure 34. The heating wire 331 is fixed to the cotton adhering structure 34 and shares a driving component with the cotton adhering structure 34. The EPE foam is conveyed from the cotton feeding structure 32, and the driving component drives the cotton adhering structure 34 to operate to adsorb the EPE foam. During this process, the heating wire 331 will first contact the EPE foam to cut it, but this straight cutting method cannot ensure that the heating wire 331 can definitely cut the EPE foam. To solve this problem, the present application adopts the rebound cotton cutting method. Specifically, the heating wire 331 can be separately arranged from the cotton adhering structure 34. The heating wire 331 is arranged in the cotton cutting structure 33. The cotton cutting structure 33 is arranged between the cotton outlet nozzle 336 and the cotton adhering structure 34. The cotton cutting structure 33 further includes a movable frame 330 for fixing the heating wire 331 and a first driving part 332 connected to the movable frame 330 to drive the heating wire 331 to operate. The first driving part 332 can drive the heating wire 331 to reciprocate. When the EPE foam is sent out with a set size, the first driving part 332 drives the heating wire 331 to move towards the EPE foam, pass through the EPE foam and then retreat and reset. Compared with the straight cutting method in the prior art, adopting the above-mentioned rebound cotton cutting method can ensure that the EPE foam is completely cut and improve the production quality.

[0054] In addition, in some embodiments, after the cotton adhering structure 34 adsorbs the EPE foam, when using the cotton cutting structure 33 to cut the EPE foam, the cotton adhering structure 34 can be controlled to move in the backward direction or remain stationary, so as to better cut the EPE foam. When the cotton adhering structure 34 moves in the backward direction or remains stationary, it can avoid the problem of poor cutting quality caused by the wrinkles generated when the EPE foam moves in the moving direction of the cotton cutting structure 33 under the action of the external force of the cotton cutting structure 33 during the process of cutting the EPE foam by the cotton cutting structure 33.

[0055] In some preferred embodiments, a cotton pasting structure 34 is provided on the side of the cotton cutting structure 33 opposite to the cotton feeding structure 32, and the cotton pasting structure 34 is used to adsorb the EPE cut by the cotton cutting structure 33 onto the surface of the material 4.

[0056] In a specific application, as Figure 7 shown, the cotton pasting structure 34 is arranged on the side of the cotton cutting structure 33 opposite to the cotton feeding structure 32. After the EPE is conveyed by the cotton feeding structure 32 and cut by the cotton cutting structure 33, the cotton pasting structure 34 adsorbs the EPE and pastes it onto the surface of the material 4, completing a complete set of cotton pasting process flow. The cotton feeding structure 32 ensures the stable conveyance of the EPE, the cotton cutting structure 33 ensures the accurate cutting of the EPE, and the cotton pasting structure 34 ensures the stable pasting of the EPE. The structures cooperate with each other and do not interfere with each other, improving the EPE pasting efficiency and pasting quality.

[0057] In some preferred embodiments, the cotton pasting structure 34 is arranged on the mounting frame 31 and includes a material pressing part 340, a second driving part 341 and a third driving part 342. The third driving part 342 is connected to the second driving part 341, and the material pressing part 340 is connected to the third driving part 342, respectively driving the material pressing part 340 to move along the direction from the cotton pasting structure 34 to the material 4 and along the direction parallel to the material 4.

[0058] In a specific application, the material pressing part 340 includes a C-shaped clamp and a vacuum suction attachment 343. The C-shaped clamp is provided with an opening facing the material 4, and the vacuum suction attachment 343 is fixed at the opening of the C-shaped clamp. The second driving part 341 can be a servo motor. When driving the material pressing part 340 to move towards the material 4, it can adapt to materials 4 of different sizes and accurately control the displacement of the material pressing part 340 during operation. The third driving part 342 can be a cylinder. When driving the material pressing part 340 to displace in a direction parallel to the material 4, its displacement stroke is fixed. During the actual packing process of the automatic winding machine 1 for the material 4, the cotton pasting structure 34 and the film winding mechanism 2 need to cooperate with each other to complete the packing of the material 4 fixed between them. During this packing process of the cotton pasting structure 34, the pearl cotton is discharged from the cotton placing tray 35 and fed through the cotton feeding structure 32. The cotton cutting structure 33 cuts off the pearl cotton. The material pressing part 340 in the cotton pasting structure 34 adsorbs the cut pearl cotton on the vacuum suction attachment 343. The third driving part 342 drives the cotton pasting structure 34 to displace a fixed stroke in a direction parallel to the material 4, actually running a predetermined stroke towards the film winding mechanism 2, so that the pearl cotton is adjacent to the film winding mechanism 2. Then, the second driving part 341 drives the cotton pasting structure 34 to move towards the material 4 and pastes the pearl cotton on the material 4. After the packing film is wound around the pearl cotton by the film winding mechanism 2 to wrap the pearl cotton on the surface of the material 4, the vacuum suction attachment releases the pearl cotton. At the same time, the third driving part 342 drives the cotton pasting structure 34 to retract, and the second driving part 341 drives the cotton pasting structure 34 to reset, and then repeats the above steps to complete the packing of the material 4. Among them, the second driving part 341 can use a precision lead screw instead of the traditional cylinder in the prior art to achieve position cotton pasting for products of different diameters.

[0059] In some preferred embodiments, the vacuum suction attachment 343 is slidably arranged on the material pressing part 340. The vacuum suction attachment 343 includes a suction tube 3431, a suction patch 3432 arranged at the end of the suction tube 3431, and a spring 3433 sleeved on the suction tube 3431. An air extraction device is connected to the suction tube 3431. The suction patch 3432 is communicated with the suction tube 3431 for adsorbing the pearl cotton. One end of the spring 3433 is connected to the suction patch 3432, and the other end is connected to the connecting plate on the material pressing part 340 for fixing the vacuum suction attachment 343. When the suction patch 3432 adsorbs the pearl cotton on the material 4 and the material 4 pushes the vacuum suction attachment 343 to move towards the cotton pasting structure 34, the spring 3433 plays a buffering role.

[0060] In specific applications, the vacuum adsorption component 343 includes an adsorption tube 3431 and an adsorption sticker 3432 arranged at the end of the adsorption tube 3431. In actual applications, the adsorption tube 3431 is connected to an exhaust device, and the adsorption sticker 3432 is connected to the adsorption tube 3431. When the adsorption sticker 3432 contacts the pearl cotton, the exhaust device draws air through the adsorption tube 3431, and the adsorption sticker 3432 connected to the adsorption tube 3431 is recessed into the adsorption tube 3431, thereby generating suction to absorb the pearl cotton. Compared with the existing structure, the plate-shaped cotton-sticking structure 34 is directly used to push the pearl cotton to the material 4 tightly, and the vacuum adsorption part 343 can more firmly adsorb the pearl cotton, and the contact area between the adsorption sticker 3432 and the pearl cotton is smaller, which is more conducive to the film wrapping mechanism 2 to wrap the pearl cotton on the material 4 with the packaging film. At the same time, after the pearl cotton is wrapped on the material 4, the exhaust device releases the gas to release the vacuum adsorption state, and the adsorption sticker 3432 will be separated from the pearl cotton, avoiding the pearl cotton being stuck down when the pressing part 340 retreats, affecting the film wrapping quality.

[0061] In the specific structure, when the pressing part 340 presses the pearl cotton onto the material 4, the material 4 will exert a reaction force on the pressing part 340. In order to prevent the reaction force from damaging the cotton-sticking structure 34, a spring 3433 can be installed on the adsorption tube 3431. When the material 4 applies a reaction force to the pressing part 340, the spring 3433 can play a good buffering role and protect the cotton-sticking structure 34 from damage.

[0062] In some preferred embodiments, the cotton sticking mechanism 3 is arranged on the automatic winding machine 1, and a fourth driving unit is provided on the lower surface of the mounting frame 31 of the cotton sticking mechanism 3, and the fourth driving unit is used to drive the cotton sticking mechanism 3 to perform lifting and lowering movements on the automatic winding machine 1.

[0063] In specific applications, the automatic wrapping machine 1 requires the cotton-applying mechanism 3 and the film-wrapping mechanism 2 to cooperate in wrapping the pearl cotton around the material 4 and completing the packaging of the material 4. The cotton-applying mechanism 3 and the film-wrapping mechanism 2 are each mounted on the automatic wrapping machine 1 via their own mounting brackets 31. To ensure that the two mechanisms can cooperate to complete the packaging process without interference or misalignment, a fourth drive unit (not shown) can be provided on the lower surface of the mounting bracket 31 of the cotton-applying mechanism 3. The fourth drive unit is used to drive the cotton-applying mechanism 3 up and down, ensuring that the cotton-applying mechanism 3 and the film-wrapping mechanism 2 remain on the same horizontal plane and flush with the material 4, facilitating packaging of the material 4.
