Description

Technical Field

[0001] This application relates to the field of coating machines, and more particularly to a double-pull coating machine. Background Art

[0002] In related technologies, in order to protect the outer surface of the parts to be coated with glue and extend the service life of the parts to be coated with glue, it is necessary to coat a protective film on the outer surface of the parts to be coated with glue. When a traditional coating machine finishes coating one part to be coated with glue and starts coating the next part to be coated with glue, the part to be coated with glue first stops moving and waits. Then, the film pulling roller moves towards the film feeding mechanism and drives the coating film to move away from the film feeding mechanism. Finally, the part to be coated with glue moves close to the coating film so that the coating film is wrapped around the outer surface of the part to be coated with glue. Since the next part to be coated with glue has to wait for the film pulling roller to pull the coating film before coating can be carried out, the coating efficiency of the coating machine is reduced. Summary of the Invention

[0003] In order to reduce the waiting time of the parts to be coated with glue for the film pulling roller to pull the coating film and improve the coating efficiency of the coating machine, this application provides a double-pull coating machine.

[0004] The double-pull coating machine provided by this application adopts the following technical solutions: A double-pull coating machine includes: a mounting frame; a coating mechanism provided on the mounting frame for wrapping a coating film around the outer peripheral wall of a part to be coated with glue and cutting the coating film; an input mechanism provided on the mounting frame. Along the conveying direction of the part to be coated with glue, the input mechanism and the coating mechanism are opposite to each other and define a film pulling gap therebetween. The input mechanism is used to convey the part to be coated with glue to the coating mechanism; a film feeding mechanism provided on the mounting frame for feeding the coating film into the film pulling gap. The coating film has adhesiveness and is adapted to face the coating mechanism.

[0005] A plurality of film pulling mechanisms are spaced apart along the radial direction of the mounting frame. Each film pulling mechanism includes a film pulling roller and a first driving assembly. The film pulling roller is located in the film pulling gap and is adapted to face and abut against the coating film. The film pulling roller is connected and cooperated with the first driving assembly. The first driving assembly is used to drive the film pulling roller to move closer to or away from the coating film, and to drive the film pulling roller to move closer to or away from the film feeding mechanism, so that the film pulling roller presses the coating film against the coating mechanism and drives the cut coating film to move away from the film feeding mechanism. The plurality of film pulling rollers sequentially drive the cut coating film to move away from the film feeding mechanism.

[0006] By adopting the above technical solution, by arranging a plurality of film pulling mechanisms, the film pulling rollers of the plurality of film pulling mechanisms successively drive the cut rubber-coated film to move away from the film feeding mechanism. After the rubber-coated film is cut, the film pulling roller of the film pulling mechanism that does not drive the rubber-coated film to move away from the film feeding mechanism drives the cut rubber-coated film to move away from the film feeding mechanism. And during the process that the film pulling roller drives the cut rubber-coated film to move away from the film feeding mechanism, the film pulling roller of one of the plurality of film pulling mechanisms moves close to the film feeding mechanism, so that the film pulling roller and the rubber-coated film are opposite to each other and wait for the next time to drive the rubber-coated film to move away from the film feeding mechanism. Compared with the prior art, the present application can reduce the waiting time of the parts to be rubber-coated for the film pulling roller to pull the rubber-coated film, and improve the rubber coating efficiency of the rubber coating machine.

[0008] By adopting the above technical solution, the first driving member drives the second driving member to drive the film pulling roller to move close to the film feeding mechanism, and the second driving member drives the film pulling roller to move close to the rubber-coated film, so that the film pulling roller presses the rubber-coated film onto the rubber coating mechanism, and the rubber-coated film adheres to the film pulling roller. Then the first driving member drives the second driving member to drive the film pulling roller to move away from the film feeding mechanism, and the film pulling roller drives the rubber-coated film to move away from the film feeding mechanism, so that the rubber-coated film is opposite to both the parts to be rubber-coated and the rubber coating mechanism, thereby realizing the technical effect that the first driving assembly drives the rubber coating roller to drive the rubber-coated film to move away from the film feeding mechanism.

[0009] Preferably, the input mechanism includes an input track, a third driving member and a plurality of pushing assemblies. The input track and the plurality of pushing assemblies are both arranged on the mounting frame.

[0010] By adopting the above technical solution, by arranging a plurality of pushing assemblies, the plurality of pushing assemblies successively push the parts to be rubber-coated to the rubber coating mechanism, so that the parts to be rubber-coated do not need to wait for the pushing assembly to move away from the rubber coating mechanism to the initial position, and thus the rubber coating efficiency of the rubber coating machine can be improved.

[0012] By adopting the above technical solution, the second driving component drives the push rod to move upward toward the part to be coated, so that the push rod and the part to be coated are stopped away from the side wall of the coating mechanism, and then the second driving component drives the push rod to drive the part to be coated to move close to the coating mechanism, thereby achieving the technical effect of the pushing component pushing the part to be coated to the coating mechanism.

[0013] Preferably, the film feeding mechanism includes a plurality of film feeding components, a flipping component and a first splicing component, the flipping component and the first splicing component are both arranged on the mounting frame, the plurality of film feeding components are arranged on the flipping component at intervals along the height direction of the mounting frame, the first splicing component is suitable for being opposite to the encapsulating film, the film feeding component is used to output the encapsulating film, when the encapsulating film of the film feeding component is transported, the flipping component drives the plurality of film feeding components to rotate so that the film feeding component with the encapsulating film is opposite to the first splicing component, the first splicing component includes a third driving component, a first splicing piece and a first cutting component, the third driving component is transmission-connected with the first splicing piece and the first cutting component, the third driving component is used to drive the first splicing piece and the first cutting component to move closer to or away from the encapsulating film, the first cutting component is used to cut the encapsulating film, the first splicing piece is used to adhere the cut encapsulating film, and press the cut encapsulating film onto the uncut encapsulating film.

[0014] By adopting the above technical scheme, after the coating film in the film feeding assembly is used up, the first cutting assembly cuts the coating film, and the cut coating film adheres to the first splicing component, and then the flipping assembly drives the multiple film feeding assemblies to rotate so that the unused film feeding assembly is opposite to the first splicing component, and then the first splicing component presses the cut coating film onto the end of the coating film of the unused film feeding assembly, and the cut coating film adheres to the end of the coating film of the unused film feeding assembly. Compared with reinstalling the coating film on the film feeding assembly, such a setting can reduce the replacement time of the coating film, thereby improving the working efficiency of the double-pull coating machine.

[0016] The film feeding mechanism further includes a first pushing assembly. The first pushing assembly is arranged on the mounting frame. The first pushing assembly and the first driving slider face each other.

[0017] By adopting the above technical solution, the first pushing assembly drives the first driving slider to move close to the first roller. The first roller moves upward along the first driving inclined surface. The first roller drives the first pressing member to move away from the first stopping member. Then the first splicing member moves away from the film feeding assembly. The first splicing member drives the cut rubber-coated film to drive the end of the unused rubber-coated film away from between the first pressing member and the first stopping member. Thus, it can prevent the end of the unused rubber-coated film from being clamped by the first pressing member and the first stopping member, and can prevent the film pulling mechanism from being unable to pull the rubber-coated film, and further improve the working reliability of the double-pulling film wrapping machine.

[0018] Preferably, the first elastic assembly includes a first connecting rod and a first elastic member.

[0021] By adopting the above technical solution, after the coated film in the film feeding assembly is used up, the second cutting component cuts the base paper of the coated film. The cut base paper of the coated film adheres to the second splicing piece. Then, the flipping component drives a plurality of film feeding assemblies to rotate so that the unused film feeding assembly faces the second splicing component. Then, the second splicing piece presses the cut base paper of the coated film onto the end of the base paper of the coated film of the unused film feeding assembly. The cut base paper of the coated film adheres to the end of the base paper of the coated film of the unused film feeding assembly. Compared with reinstalling the coated film on the film feeding assembly, such a setting can reduce the replacement time of the coated film, thereby improving the working efficiency of the double-drawing film wrapping machine.

[0022] Preferably, the film feeding assembly includes a second pressing member, a second stopping member and a second elastic component. The second pressing member is movably arranged on the second stopping member.

The second pushing component and the second driving slider face each other. The second pushing component is used for driving the second driving slider to move closer to the second roller so that the second roller drives the second pressing member to move away from the second stopping member.

[0024] By adopting the above technical solution, the second driving assembly drives the second driving slider to move closer to the second roller. The second roller moves upward along the second driving inclined surface. The second roller drives the second pressing member to move away from the second stopping member. Then, the second splicing member moves away from the film feeding assembly. The second splicing member drives the base paper of the cut rubber-coated film to drive the end of the base paper of the unused rubber-coated film away from between the second pressing member and the second stopping member. Thus, it is possible to prevent the end of the base paper of the unused rubber-coated film from being clamped by the second pressing member and the second stopping member, and prevent the recycling assembly from being unable to recycle the base paper of the rubber-coated film. Furthermore, the working reliability of the double-pull film wrapping machine can be improved.

Detailed implementation manners

[0030] The following will further describe the present application in detail with reference to the attached Figures 1-17 drawings.

[0031] An embodiment of the present application discloses a double-drawing film wrapping machine 100.

[0032] Referring to Figures 1-4 , the double-drawing film wrapping machine 100 according to the embodiment of the present application includes: a mounting frame 1, a film wrapping mechanism 3, an input mechanism 4, a film feeding mechanism 5, and a plurality of film drawing mechanisms 6.

[0033] The film wrapping mechanism 3, the input mechanism 4, and the film feeding mechanism 5 are all arranged on the mounting frame 1. The film wrapping mechanism 3 is used for wrapping the rubber-coated film 51 around the outer peripheral wall of the part 2 to be rubber-coated and cutting the rubber-coated film 51. Along the conveying direction of the part 2 to be rubber-coated, the input mechanism 4 and the film wrapping mechanism 3 are opposite to each other and define a film drawing gap 41 therebetween. The input mechanism 4 is used for conveying the part 2 to be rubber-coated to the film wrapping mechanism 3, and the film feeding mechanism 5 is used for feeding the rubber-coated film 51 into the film drawing gap 41. The rubber-coated film 51 has adhesiveness and is adapted to face the film wrapping mechanism 3.

[0034] Specifically, along the conveying direction of the part 2 to be rubber-coated, the input mechanism 4 is located on the upstream side of the film wrapping mechanism 3. Along the height direction of the mounting frame 1, the film feeding mechanism 5 is located above the film wrapping mechanism 3. The conveying direction of the part 2 to be rubber-coated may refer to Figure 1 the direction from left to right in Figure 1 and the height direction of the mounting frame 1 may refer to

[0035] the up-down direction in

[0036] The parts to be coated are placed on the input mechanism 4. The first driving component 62 drives the film pulling roller 61 to move upward and approach the film feeding mechanism 5. Then, the first driving component 62 drives the film pulling roller 61 to approach the coating film 51. The coating film 51 adheres to the film pulling roller 61. Then, the first driving component 62 drives the film pulling roller 61 to drive the coating film 51 to move downward and away from the film feeding mechanism 5, so that the coating film 51 is opposite to both the film coating mechanism 3 and the parts to be coated 2. The input mechanism 4 conveys the parts to be coated 2 to the film coating mechanism 3. The parts to be coated 2 drive the coating film 51 located in the film pulling gap 41 to extend into the film coating mechanism 3. The film coating mechanism 3 coats the coating film 51 on the outer peripheral wall of the parts to be coated 2. Then, the film pulling roller 61 of the film pulling mechanism 6 that does not drive the coating film 51 to move away from the film feeding mechanism 5 presses the coating film 51 against the film coating mechanism 3. Finally, the film coating mechanism 3 cuts off the coating film 51, thus completing the film coating of the parts to be coated 2.

[0037] In some specific embodiments, there are two film pulling mechanisms 6. The two film pulling mechanisms 6 are arranged at intervals along the first direction of the mounting frame 1. One of the two film pulling mechanisms 6 is the first film pulling mechanism 6, and the other is the second film pulling mechanism 6. The first direction of the mounting frame 1 can be Figure 1 the front-back direction, and the conveying mechanism is located between the two film pulling mechanisms 6.

[0038] When coating the first parts to be coated 2, the first driving component 62 of the first film pulling mechanism 6 drives the corresponding film pulling roller 61 to move upward and approach the film pulling mechanism 6. When the film pulling roller 61 of the first film pulling mechanism 6 moves to be opposite to the coating film 51, the first driving component 62 of the first film pulling mechanism 6 drives the corresponding film pulling roller 61 to approach the coating film 51. The coating film 51 adheres to the film pulling roller 61. Then, the first driving component 62 of the first film pulling mechanism 6 drives the corresponding film pulling roller 61 to drive the coating film 51 to move downward and away from the film pulling mechanism 6. And during the process that the film pulling roller 61 of the first film pulling mechanism 6 drives the coating film 51 to move downward and away from the film pulling mechanism 6, the first driving component 62 of the second film pulling mechanism 6 drives the corresponding film pulling roller 61 to move upward and approach the film feeding mechanism 5.

[0039] After the encapsulation mechanism 3 finishes encapsulating the parts 2 to be encapsulated, the first driving component 62 of the second film pulling mechanism 6 drives the corresponding film pulling roller 61 to move close to the encapsulation film 51. The film pulling roller 61 of the second film pulling mechanism 6 presses the encapsulation film 51 against the encapsulation mechanism 3, and the encapsulation film 51 adheres to the film pulling roller 61 of the second film pulling mechanism 6. The first driving component 62 of the first film pulling mechanism 6 drives the corresponding film pulling roller 61 to move away from the encapsulation film 51. Then, the encapsulation mechanism 3 cuts the encapsulation film 51 covering the parts 2 to be encapsulated. The first driving component 62 of the second film pulling mechanism 6 drives the corresponding film pulling roller 61 to drive the encapsulation film 51 to move downward away from the film feeding mechanism 5, so that the encapsulation film 51 is opposite to both the encapsulation mechanism 3 and the parts 2 to be encapsulated. And during the process that the film pulling roller 61 of the second film pulling mechanism 6 drives the encapsulation film 51 to move downward away from the film feeding mechanism 5, the first driving component 62 of the first film pulling mechanism 6 drives the corresponding film pulling roller 61 to move upward close to the film feeding mechanism 5.

[0040] By alternately driving the encapsulation film 51 to move away from the film feeding mechanism 5 by the first film pulling mechanism 6 and the second film pulling mechanism 6, the encapsulation film 51 can be made opposite to the parts 2 to be encapsulated and the encapsulation mechanism 3, so as to reduce the waiting time of the parts 2 to be encapsulated for the film pulling roller 61 to pull the encapsulation film 51 and improve the encapsulation efficiency of the encapsulation machine.

[0041] Thus, by arranging multiple film pulling mechanisms 6, the film pulling rollers 61 of the multiple film pulling mechanisms 6 drive the cut encapsulation film 51 to move away from the film feeding mechanism 5 in sequence. After the encapsulation film 51 is cut, the film pulling roller 61 of the film pulling mechanism 6 that does not drive the encapsulation film 51 to move away from the film feeding mechanism 5 drives the cut encapsulation film 51 to move away from the film feeding mechanism 5. And during the process that the film pulling roller 61 drives the cut encapsulation film 51 to move away from the film feeding mechanism 5, the film pulling roller 61 of one of the multiple film pulling mechanisms 6 in the multiple film pulling mechanisms 6 moves close to the film feeding mechanism 5, so that the film pulling roller 61 and the encapsulation film 51 are opposite and wait to drive the encapsulation film 51 to move away from the film feeding mechanism 5 next time. Compared with the prior art, the application can reduce the waiting time of the parts 2 to be encapsulated for the film pulling roller 61 to pull the encapsulation film 51 and improve the encapsulation efficiency of the encapsulation machine.

[0042] Refer to Figure 4 and Figure 5 In some embodiments of the present application, the first driving component 62 includes a first driving member 621 and a second driving member 622. The first driving member 621 is arranged on the mounting frame 1. The first driving member 621 and the second driving member 622 are connected and cooperate with each other. The film pulling roller 61 and the second driving member 622 are connected and cooperate with each other. The first driving member 621 drives the second driving member 622 to drive the film pulling roller 61 to move close to or away from the film feeding mechanism 5, and the second driving member 622 drives the film pulling roller 61 to move close to or away from the encapsulation film 51.

[0043] Specifically, the first driving member 621 drives the second driving member 622 to drive the film-drawing roller 61 to move close to the film-feeding mechanism 5, and the second driving member 622 drives the film-drawing roller 61 to move close to the coating film 51, so that the film-drawing roller 61 presses the coating film 51 onto the coating mechanism, and the coating film 51 adheres to the film-drawing roller 61. Then the first driving member 621 drives the second driving member 622 to drive the film-drawing roller 61 to move away from the film-feeding mechanism 5, and the film-drawing roller 61 drives the coating film 51 to move away from the film-feeding mechanism 5, so that the coating film 51 is opposite to the part to be coated 2 and the coating mechanism 3, thereby achieving the technical effect that the first driving component 62 drives the coating roller to drive the coating film 51 to move away from the film-feeding mechanism 5.

[0044] After the encapsulation mechanism completes encapsulating the part 2 to be encapsulated, the second driving member 622 drives the film-drawing roller 61 to move away from the encapsulating film 51 , and the first driving member 621 drives the second driving member 622 to drive the film-drawing roller 61 to move closer to the film-feeding mechanism 5 .

[0045] In some specific embodiments, the first driving member 621 is preferably a rodless cylinder, and the second driving member 622 is preferably a cylinder.

[0046] Further, refer to Figure 5 The film-drawing mechanism 6 also includes an electromagnetic brake 63 and a connecting bracket 64. The connecting bracket 64 is connected and cooperated with the second driving member 622. The film-drawing roller 61 is pivotally mounted on the connecting bracket 64. The electromagnetic brake 63 is arranged on the connecting bracket 64, and the electromagnetic brake 63 is transmission-connected to the film-drawing roller 61. The electromagnetic brake 63 is used to lock the film-drawing roller 61, thereby preventing the film-drawing roller 61 from rotating around the central axis of the film-drawing roller 61, and preventing the film-drawing roller 61 from rotating when the film-drawing roller 61 pulls the coating film 51, causing the coating film 51 and the film-drawing roller 61 to separate.

[0047] Reference Figure 1 , Figure 6 and Figure 7 In some embodiments of the present application, the input mechanism 4 includes an input track 42, a third driving member 43 and a plurality of pushing components 44. The input track 42 and the plurality of pushing components 44 are both provided on the mounting frame 1. The plurality of pushing components 44 are arranged sequentially along the first direction of the mounting frame 1. The input track 42 is opposite to the film-wrapping mechanism 3, and a film-pulling gap 41 is defined between the input track 42 and the film-wrapping mechanism 3. The part 2 to be coated is suitable for being placed on the input track 42. The third driving member 43 is provided on the mounting frame 1. The third driving member 43 is used to drive the input track 42 to move closer to or away from the film-wrapping mechanism 3 to adjust the width of the film-pulling gap 41. The plurality of pushing components 44 are all used to push the part 2 to be coated to the film-wrapping mechanism 3, and the plurality of pushing components 44 sequentially push the part 2 to be coated to the film-wrapping mechanism 3.

[0048] Specifically, after the part 2 to be rubber-coated is placed on the input track 42, the pushing component 44 moves close to the film wrapping mechanism 3 to push the part 2 to be rubber-coated to the film wrapping mechanism 3. After the part 2 to be rubber-coated enters the film wrapping mechanism 3, the pushing component 44 moves away from the film wrapping mechanism 3 to the initial position.

[0049] In some specific embodiments, there are two pushing components 44. One of the two pushing components 44 is the first pushing component 44, and the other is the second pushing component 44.

[0050] When there are multiple parts 2 to be rubber-coated placed on the input track 42, the first pushing component 44 pushes the part 2 to be rubber-coated to the film wrapping mechanism 3, and then the first pushing component 44 moves away from the film wrapping mechanism 3. During the process of the first pushing component 44 moving away from the film wrapping mechanism 3, the second pushing component 44 pushes the part 2 to be rubber-coated to the film wrapping mechanism 3, and then the second pushing component 44 moves away from the film wrapping mechanism 3. The first pushing component 44 and the second pushing component 44 alternately push the part 2 to be rubber-coated to the film wrapping mechanism 3.

[0051] By setting multiple pushing components 44, the multiple pushing components 44 sequentially push the part 2 to be rubber-coated to the film wrapping mechanism 3, so that the part 2 to be rubber-coated does not need to wait for the pushing component 44 to move away from the film wrapping mechanism 3 to the initial position, thereby improving the film wrapping efficiency of the film wrapping machine.

[0052] Moreover, when the film pulling roller 61 drives the rubber-coated film 51 to move away from the film feeding mechanism 5 and when the film pulling roller 61 moves close to the film feeding mechanism 5, the third driving part 43 drives the input track 42 to move away from the film wrapping mechanism 3 to increase the width of the film pulling gap 41, so as to prevent the input track 42 from interfering with the film pulling roller 61, and to avoid the situation that the film pulling roller 61 cannot drive the rubber-coated film 51 to move away from the film feeding mechanism 5 and that the film pulling roller 61 cannot move close to the film feeding mechanism 5, thereby improving the working reliability of the double-film-pulling film wrapping machine 100.

[0053] When the film pulling roller 61 drives the rubber-coated film 51 to move away from the film feeding mechanism 5 to a preset position, the third driving part 43 drives the input track 42 to move close to the film wrapping mechanism 3 to reduce the width of the film pulling gap 41, so as to avoid the width of the film pulling gap 41 being too large, the part 2 to be rubber-coated falling into the film pulling gap 41, and the film wrapping mechanism 3 being unable to wrap the rubber-coated film 51 around the part 2 to be rubber-coated.

[0054] Furthermore, multiple pushing components 44 can also be arranged on the input track 42.

[0055] In some specific embodiments, the third driving part 43 is preferably a cylinder.

The second driving assembly 442 is used to drive the push rod 441 to move closer to or away from the coating mechanism 3, and to drive the push rod 441 to move closer to or away from the part to be coated 2. The push rod 441 is used to push the part to be coated 2 to move to the coating mechanism 3.

[0057] Specifically, along the height direction of the mounting frame 1, the part to be coated 2 is located above the push rod 441, and the second driving component 442 drives the push rod 441 to move upward toward the part to be coated 2, so that the push rod 441 and the part to be coated 2 are away from the side wall of the coating mechanism 3, and then the second driving component 442 drives the push rod 441 to drive the part to be coated 2 to move toward the coating mechanism 3, thereby achieving the technical effect of the pushing component 44 pushing the part to be coated 2 to the coating mechanism 3.

[0058] After the part to be coated 2 enters the coating mechanism 3, the second driving component 442 drives the push rod 441 to move downward away from the part to be coated 2, and then the second driving component 442 drives the push rod 441 to move away from the coating mechanism 3 to the initial position, thereby avoiding interference between the push rod 441 and the part to be coated 2 on the input track 42 during the movement of the push rod 441 away from the coating mechanism 3. The push rod 441 drives the part to be coated 2 to move away from the coating mechanism 3, thereby improving the working reliability of the double-pull coating machine 100.

[0059] Further, refer to Figure 7 The second driving assembly 442 includes a fourth driving member 4421 and a fifth driving member 4422. The fourth driving member 4421 is arranged on the mounting frame 1. The fifth driving member 4422 is connected to the fourth driving member 4421 in transmission connection. The push rod 441 is connected and matched with the fifth driving member 4422.

The motor drives the screw to drive the fifth driving member 4422 to move closer to or away from the coating mechanism 3, so that the fifth driving member 4422 drives the push rod 441 to move closer to or away from the coating mechanism 3. The fifth driving member 4422 is preferably a cylinder.

That is to say, after the encapsulating film 51 in the film feeding component 52 is used up, the flipping component 53 drives the film feeding component 52 with the encapsulating film 51 to be opposite to the first splicing component 54.

The second pushing component 58 is used to drive the second driving slider 5261 to move close to the second roller 5251, so that the second roller 5251 drives the second pressure member 525 to move away from the second stop member 526.

[0098] When the backing paper of the coated film 51 to be cut by the second splicing member 572 is pressed against the end of the backing paper of the coated film 51 of the unused film feeding assembly 52, and when the second splicing member 572 does not move away from the film feeding assembly 52, the second pushing assembly 58 drives the second driving slider 5261 to move closer to the second roller 5251. The second roller 5251 moves upward along the second driving inclined surface 5262. The second roller 5251 drives the second pressing member 525 to move away from the second stopping member 526. Then the second splicing member 572 moves away from the film feeding assembly 52. The second splicing member 572 drives the backing paper of the cut coated film 51 to drive the end of the backing paper of the unused coated film 51 to leave between the second pressing member 525 and the second stopping member 526, so as to prevent the end of the backing paper of the unused coated film 51 from being clamped by the second pressing member 525 and the second stopping member 526, and prevent the recycling assembly 56 from being unable to recycle the backing paper of the coated film 51, thereby improving the working reliability of the double-pull film wrapping machine 100.

[0099] After the end of the backing paper of the unused coated film 51 leaves between the second pressing member 525 and the second stopping member 526, the second pushing assembly 58 moves away from the second driving slider 5261. The second elastic assembly 527 drives the second pressing member 525 to move closer to the second stopping member 526. The second roller 5251 moves downward along the second driving inclined surface 5262. The second roller 5251 drives the second driving slider 5261 to move closer to the second pushing assembly 58.

[0100] Further, the second pushing assembly 58 includes a thirteenth driving member 581 and a second push plate 582. The thirteenth driving member 581 is arranged on the mounting frame 1. The second pushing and the thirteenth driving member 581 are connected and matched. The second push plate 582 faces the second driving slider 5261. The thirteenth driving member 581 is used to drive the second push plate 582 to drive the second driving slider 5261 to move closer to the second roller 5251.

[0102] Refer to Figure 10 , in some embodiments of the present application, the second elastic assembly 527 includes a second connecting rod 5271 and a second elastic member 5272. Along the height direction of the mounting frame 1, the lower end of the second connecting rod 5271 is connected and matched with the second stopping member 526. The upper end of the second connecting rod 5271 passes through the second pressing member 525, and a second limiting portion 5273 is provided at the upper end of the second connecting rod 5271. The second elastic member 5272 is elastically deformably arranged between the second limiting portion 5273 and the second pressing member 525, and the second elastic member 5272 is sleeved on the outer peripheral wall of the second connecting rod 5271. The second elastic member 5272 is used to drive the second pressing member 525 to move closer to the second stopping member 526.

[0103] When the second roller 5251 drives the second pressing member 525 to move away from the second stopping member 526, the second elastic member 5272 is compressed. After the second pushing assembly 58 moves away from the second driving slider 5261, the second elastic member 5272 drives the second pressing member 525 to move closer to the second stopping member 526, so that the technical effect of the second elastic assembly 527 driving the second pressing member 525 to move closer to the second stopping member 526 can be achieved.

[0104] In some specific embodiments, the second elastic member 5272 is preferably a spring.

The third cutting assembly 33 is located above the second rubber-coated roller assembly 32, and the third cutting assembly 33 is located on the side of the first rubber-coated roller assembly 31 away from the input mechanism 4.

[0106] Both the first rubber-coated roller assembly 31 and the second rubber-coated roller assembly 32 are used to press the rubber coating film 51 onto the outer peripheral wall of the part to be rubber-coated 2.

The film pulling roller 61 presses the rubber coating film 51 onto the first rubber-coated roller assembly 31.

[0107] When the input mechanism 4 conveys the part to be rubber-coated 2 to abut against the rubber coating film 51, the second rubber-coated roller assembly 32 moves closer to the first rubber-coated roller assembly 31. The second rubber-coated roller 323 presses the rubber coating film 51 onto the end wall of the part to be rubber-coated 2 opposite to the rubber coating film 51. Then the second rubber-coated roller assembly 32 moves away from the first rubber-coated roller assembly 31. The input mechanism 4 conveys the part to be rubber-coated 2 into the rubber coating gap 34. The first rubber-coated roller assembly 31 presses the rubber coating film 51 onto the upper end wall of the part to be rubber-coated 2, and the second rubber-coated roller assembly 32 presses the rubber coating film 51 onto the lower end wall of the part to be rubber-coated 2. After the rubber coating film 51 covers the outer peripheral wall of the part to be rubber-coated 2, the third cutting assembly 33 cuts the rubber coating film 51, thus completing the rubber coating of the part to be rubber-coated 2.

[0108] Further, the encapsulation gap 34 can be set according to the height dimension of the part 2 to be encapsulated, so that the first encapsulation roller assembly 31 abuts against the upper end wall of the part 2 to be encapsulated, and the second encapsulation roller assembly 32 abuts against the lower end wall of the part 2 to be encapsulated.

[0109] Further, referring to Figure 15 and Figure 16 , the first encapsulation roller assembly 31 includes a fourth connecting plate 311, a fourteenth driving member 312, a first encapsulation roller 313 and an abutting roller 314.

The third cutting assembly 33 is arranged on the fourth connecting plate 311.

[0110] By driving the first encapsulation roller 313 and the abutting roller 314 to move closer to or away from the second encapsulation roller assembly 32 by the fourteenth driving member 312, the size of the encapsulation gap 34 can be adjusted, so that the encapsulation gap 34 can match parts 2 to be encapsulated with different height dimensions, and thus the use experience of the double-pulling film wrapping machine 100 can be improved.

[0111] In some specific embodiments, the fourteenth driving member 312 includes a motor and a lead screw. The motor and the lead screw are connected and cooperated, and the fourth connecting plate 311 is in transmission connection with the lead screw.

The sixteenth driving member 322 is used to drive the fifth connecting plate 321 to drive the second rubber-coated roller 323 to move closer to or away from the first rubber-coated roller assembly 31.

[0115] By driving the second rubber-coated roller 323 to move closer to or away from the first rubber-coated roller assembly 31 through the sixteenth driving member 322, the size of the rubber coating gap 34 can be adjusted, so that the rubber coating gap 34 can match the parts to be rubber-coated 2 with different height dimensions, and thus the use experience of the double-pull film wrapping machine 100 can be improved.

[0116] In some specific embodiments, the sixteenth driving member 322 includes a motor and a lead screw. The motor and the lead screw are connected and cooperated. The fifth connecting plate 321 is in transmission connection with the lead screw.
