Description

Technical Field

[0001] This application relates to the field of hot melt adhesive film production technology, and in particular to a cooling granulator for hot melt adhesive film production. Background Technology

[0002] Hot melt adhesive film is a film-like hot melt adhesive product with release paper or no release paper as the base material. It has environmentally friendly characteristics of being solvent-free, odorless, and free of VOCs emissions. According to the material, it can be divided into EVA, PA, PES, PO, TPU and other types.

[0003] When producing hot melt adhesive film, it is usually necessary to use a cooling granulator to extrude and cool the mixed molten adhesive material in sequence, and cut it into uniform hot melt adhesive particles. Then, the hot melt adhesive particles are remelted and further mixed, and then evenly coated onto release paper or release film through a slit die. Finally, it is cooled and cured into a film, and then rolled up.

[0004] A cooling granulator exists in the prior art, comprising a melt extrusion mechanism, a conveying mechanism, a cooling tank, and a pelletizing mechanism. The melt extrusion mechanism melts and extrudes the mixed rubber compound. The cooling tank, located between the melt extrusion mechanism and the pelletizing mechanism, has an opening at the top for storing coolant. The conveying mechanism feeds the extruded rubber strip into the cooling tank and then conveys the cooled rubber strip to the pelletizing mechanism. The pelletizing mechanism cuts the cooled rubber strip into uniform granules. In operation, the melt extrusion mechanism melts and extrudes the mixed rubber compound, the conveying mechanism feeds the extruded rubber strip into the cooling tank, and then conveys the cooled rubber strip to the pelletizing mechanism, which cuts the cooled rubber strip into uniform granules.

[0005] Regarding the aforementioned technologies, in order to increase the time the adhesive strip spends in the cooling tank, existing technologies generally use several vertically distributed guide rollers in the cooling tank, causing the adhesive strip to meander vertically within the cooling tank. This means that at the start of production, personnel must manually pass the adhesive strip through the guide rollers before it can be moved to the pelletizing mechanism, increasing the workload of personnel and consequently reducing the production efficiency of hot melt adhesive granules. Therefore, improvements are needed. Summary of the Invention

[0006] To facilitate the passing of adhesive strips between several guide rollers, this application provides a cooling granulator for hot melt adhesive film production.

[0007] This application provides a cooling granulator for hot melt adhesive film production, which adopts the following technical solution: A cooling granulator for hot melt adhesive film production includes a melt extrusion mechanism, a cooling tank, and a pelletizing mechanism. The cooling tank is located between the melt extrusion mechanism and the pelletizing mechanism, and has an opening at the top for holding coolant. A guiding mechanism is also provided in the cooling tank. The guiding mechanism includes an upper frame, a lower frame, and a lifting assembly. Several guide rollers are provided on both the upper and lower frames. Each guide roller is rotatably connected to a corresponding upper or lower frame. The top ends of the guide rollers are flush with the top of the cooling tank and are used to support the adhesive strip extruded by the melt extrusion mechanism. The lifting assembly is used to drive the lower frame to move into the cooling tank.

[0008] By adopting the above technical solution, compared with the prior art, when the production of the rubber strip begins, relevant personnel need to manually pass the rubber strip through several guide rollers before it can move into the pelletizing mechanism, which increases the workload of relevant personnel and leads to a decrease in pelletizing efficiency. This application, through the setting of the guiding mechanism, allows the rubber strip to move from one end of the cooling pool to the other end under the guidance of the guide rollers on the upper and lower setting frames after it is extruded by the melt extrusion mechanism. This allows relevant personnel to control the lifting component to make the lower setting frame enter the cooling pool downwards, causing the rubber strip to meander in the height direction of the cooling pool, thus eliminating the need for relevant personnel to manually pass the rubber strip through several guide rollers, effectively improving the production efficiency of hot melt adhesive granules. At the same time, relevant personnel can also adjust the time the rubber strip spends in the cooling pool by controlling the lifting component, thereby adjusting the cooling time of the rubber strip and ensuring the cooling effect of the rubber strip.

[0009] Preferably, the cooling pool is inclined at one end away from the melt extrusion mechanism and towards the pelletizing mechanism. The cooling pool is also provided with a conveying mechanism, which includes a conveying frame, a clamping assembly and a driving assembly. The conveying frame is slidably connected to the cooling pool. The pelletizing mechanism is located on the sliding path of the conveying frame. The driving assembly is used to drive the conveying frame to slide. The clamping assembly is disposed on the conveying frame and is used to clamp the cooled rubber strip.

[0010] By adopting the above technical solution and configuring the conveying mechanism, one end of the rubber strip can be clamped by the clamping component on the conveying frame after passing through the upper and lower mounting frames. This clamping component fixes one end of the rubber strip, reducing the probability of the rubber strip detaching from the guide roller when the lower mounting frame shifts. At the same time, the drive component can also convey the rubber strip to the pelletizing mechanism after the lower mounting frame has shifted, thereby realizing the transportation of the rubber strip. This effectively realizes the automated transportation of the rubber strip between the melt extrusion mechanism and the pelletizing mechanism, thereby improving the efficiency of hot melt adhesive granule preparation. In addition, the inclined setting at the end of the cooling pool effectively allows the residual coolant on the rubber strip to flow downward into the cooling pool through the inclined part after the rubber strip exits the cooling pool, thereby reducing the amount of residual coolant on the rubber strip.

[0011] Preferably, the conveying mechanism further includes a conveying guide rail located on the side of the cooling pool near the pelletizing mechanism. One end of the conveying guide rail is close to the lower mounting frame, and the other end extends along the inclined direction of the end of the cooling pool and is close to the pelletizing mechanism. One end of the conveying frame is embedded in the conveying guide rail and abuts against the inner wall of the conveying guide rail. The driving assembly is used to drive the conveying frame to slide along the extension direction of the conveying guide rail.

[0012] By adopting the above technical solution, the setting of the conveying guide rail allows the conveying frame to slide along the extension direction of the conveying guide rail, thereby enabling the conveying frame to drive the rubber strip to slide along the inclined direction of the end of the cooling pool. This ensures that the residual coolant on the rubber strip can flow back into the cooling pool smoothly along the inclined part of the cooling pool, while also ensuring the stability of the conveying frame during displacement.

[0013] Preferably, the clamping assembly includes clamping plates and clamping members, and the number of clamping plates and clamping members is set to two. Each clamping plate has one end rotatably connected to the conveyor frame and the other end used to clamp the end of the rubber strip. Each clamping member is used to drive the corresponding clamping plate to rotate.

[0014] By adopting the above technical solution and configuring the clamping component, the clamping component can drive the clamping plate to rotate, thereby clamping the end of the rubber strip after the clamping plate rotates, thus achieving the clamping of the rubber strip. As a result, the conveyor can smoothly pass through the clamping component and drive the rubber strip to move.

[0015] Preferably, the clamping component includes a transmission frame and a drive frame. One end of the transmission frame is rotatably connected to the corresponding clamping plate, and the other end is rotatably connected to the corresponding drive frame. The drive frame is slidably connected to the conveyor frame. A drive component is also provided on the cooling pool. The drive component is used to drive the drive frame to slide when the conveyor frame is close to the lower frame.

[0016] By adopting the above technical solution and configuring the clamping component, when it is necessary to drive the clamping plate to rotate, the driving component can drive the driving frame to slide during the sliding process of the conveyor frame, thereby causing the driving frame to drive the clamping plate to rotate through the transmission frame, thus achieving the driving of the clamping plate to rotate and ensuring the clamping effect of the rubber strip.

[0017] Preferably, the driving component includes a driving slide rail, on which two driving slots are formed. The driving slots are arranged one-to-one with the driving frame. Each driving slot extends along the extension direction of the conveying guide rail. Both ends of each driving slot are inclined away from the driving slide rail. One end of each driving frame extends into the corresponding driving slot and abuts against the inner wall of the corresponding driving slot.

[0018] By adopting the above technical solution and setting the drive slide rail, one end of the drive frame can slide in the corresponding drive groove during the sliding process of the conveyor frame. As the conveyor frame slides closer to the lower frame or closer to the pelletizing mechanism, the inner wall of the inclined part of the drive groove can push the drive frame to slide by abutting against it, thereby driving the sliding of the drive frame. This effectively realizes the linkage between the output frame and the clamping plate, thereby saving the active device for driving the clamping plate to rotate, thus reducing the overall weight and volume of the output frame, and facilitating the setting and driving of the output frame.

[0019] Preferably, the conveyor frame is also provided with a number of guide wheels, each of which is rotatably connected to the conveyor frame and distributed along the extension direction of the conveyor rail. Each guide wheel is embedded inside the conveyor rail and abuts against the inner wall of the conveyor rail.

[0020] Preferably, the lower frame includes a lifting frame and several sliding frames. The lifting assembly is used to drive the lifting frame to move into the cooling pool. The several sliding frames are located on opposite sides of the lifting frame and are slidably connected to the lifting frame. The sliding direction is different from the sliding direction of the lifting frame. Each sliding frame is slidably connected to the cooling pool and the sliding direction is inclined to the height direction of the cooling pool. The lifting frame and each sliding frame are provided with guide rollers.

[0021] By adopting the above technical solution, the lifting frame and the sliding frame are configured such that when the lifting assembly drives the lifting frame into the cooling pool, the sliding frame can slide relative to the lifting frame, thereby increasing the distance between the two sliding frames. This allows the rubber strips to be evenly distributed in the cooling pool and effectively increases the distance between the sliding frame and the corresponding upper frame, thereby increasing the length of the rubber strips in the cooling pool and the time the rubber strips are in the cooling pool, thus improving the cooling effect on the rubber strips.

[0022] Preferably, the number of upper mounting frames is set to two, and they are located between the two sliding frames. Each of the above-mentioned conveying frames is slidably connected to the cooling pool, and the sliding direction is different from the sliding direction of the lifting frame. The guiding mechanism also includes a linkage component, through which the lifting frame drives each of the upper mounting frames to slide.

[0023] By adopting the above technical solution, the upper mounting frame and linkage components are configured so that when the lifting frame moves, the corresponding upper mounting frame can slide through the linkage components, thereby changing the spacing between the upper mounting frames. This results in a more uniform distribution of the rubber strips, which in turn makes the stress distribution inside the rubber strips more uniform. This effectively reduces the probability of the rubber strips being stretched or even broken due to uneven stress inside the rubber strips, while also effectively ensuring the cooling effect on the rubber strips.

[0024] Preferably, the linkage component includes two linkage frames, each corresponding to one of the upper mounting frames. One end of each linkage frame is rotatably connected to the corresponding upper mounting frame, and the other end is inclined and rotatably connected to the lifting frame.

[0025] By adopting the above technical solution and setting the linkage frame, when the lifting frame slides downward, the lifting frame can drive the linkage frame to rotate relative to itself, thereby causing the linkage frame to drive the corresponding upper setting frame to slide, thus realizing the driving of the upper setting frame to slide. This effectively realizes the linkage between the upper setting frame and the lifting frame, thereby saving the active device required to drive the upper setting frame to slide and reducing the weight and volume of the upper setting frame.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The guiding mechanism is designed so that after the rubber strip is extruded by the melt extrusion mechanism, it can move from one end of the cooling tank to the other under the guidance of the guide rollers on the upper and lower frames. This allows personnel to control the lifting components to lower the lower frame into the cooling tank while the rubber strip continues to be conveyed, causing the rubber strip to meander along the height of the cooling tank. This eliminates the need for personnel to manually pass the rubber strip through several guide rollers, effectively improving the production efficiency of hot melt adhesive granules. At the same time, personnel can also control the lifting components to adjust the time the rubber strip spends in the cooling tank, thereby adjusting the cooling time of the rubber strip and ensuring the cooling effect. 2. The conveying mechanism is designed so that after one end of the rubber strip passes through the upper and lower mounting frames, it can be gripped by the clamping components on the conveying frame. This fixes one end of the rubber strip in place, reducing the chance of the rubber strip detaching from the guide roller when the lower mounting frame shifts. At the same time, the drive component can also convey the rubber strip to the pelletizing mechanism after the lower mounting frame has shifted, thus realizing the transportation of the rubber strip. This effectively realizes the automated transportation of the rubber strip between the melt extrusion mechanism and the pelletizing mechanism, thereby improving the efficiency of hot melt adhesive granule preparation. In addition, the inclined setting at the end of the cooling pool effectively allows the residual coolant on the rubber strip to flow downward into the cooling pool through the inclined part after the rubber strip exits the cooling pool, thereby reducing the amount of residual coolant on the rubber strip. 3. The arrangement of the lifting frame, sliding frame, and linkage components allows the sliding frame to slide relative to the lifting frame when the lifting component drives the lifting frame into the cooling pool, and the upper mounting frame can also slide. This increases the distance between the two sliding frames and the mounting frame, allowing the rubber strips to be evenly distributed in the cooling pool. It also effectively increases the distance between the sliding frames and the corresponding upper mounting frames, thereby increasing the length of the rubber strips in the cooling pool and the time the rubber strips are in the cooling pool, thus improving the cooling effect on the rubber strips.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a cooling granulator for hot melt adhesive film production. (Refer to...) Figure 1 and Figure 2 The cooling granulator for hot melt adhesive film production includes a melt extrusion mechanism 1, a cooling tank 2, and a pelletizing mechanism 3. The cooling tank 2 is located between the melt extrusion mechanism 1 and the pelletizing mechanism 3, and has an opening at the top for holding coolant. A guiding mechanism 4 is also provided inside the cooling tank 2. The guiding mechanism 4 includes an upper mounting frame 41, a lower mounting frame 42, and a lifting assembly 43. Several guide rollers 44 are provided on both the upper mounting frame 41 and the lower mounting frame 42. Each guide roller 44 is rotatably connected to the corresponding upper mounting frame 41 or lower mounting frame 42. The top ends of the guide rollers 44 are flush with the top of the cooling tank 2 and are used to support the adhesive strip extruded by the melt extrusion mechanism 1. The lifting assembly 43 drives the lower mounting frame 42 to move into the cooling tank 2.

[0034] Reference Figure 1 In this embodiment of the application, the melt extrusion mechanism 1 is configured as a screw extruder. The screw extruder is equipped with a heating structure for heating and melting the material in its own chamber. The screw extruder is used to extrude the mixed material after melting. The screw extruder is prior art, so it will not be described in detail here.

[0035] Reference Figure 1 The cooling tank 2 is placed on the ground and located between the melt extrusion mechanism 1 and the pelletizing mechanism 3. The top of the cooling tank 2 is open to hold the coolant. The end of the cooling tank 2 away from the melt extrusion mechanism 1 (i.e., the end along its own length, i.e., the end in the direction of the rubber strip conveying) is inclined away from the melt extrusion mechanism 1 to form an inclined surface.

[0036] Reference Figure 2 The lower frame 42 includes a lifting frame 421 and several sliding frames 422. In this embodiment, the number of sliding frames 422 is set to two. The lifting frame 421 is located inside the cooling pool 2, and the length direction of the lifting frame 421 is the same as the length direction of the cooling pool 2. The lifting frame 421 is slidably connected to the inner wall of the cooling pool 2 via a slide rail, and the sliding direction is the height direction of the cooling pool 2.

[0037] Reference Figure 2 The top of the lifting frame 421 extends out of the cooling pool 2 along one side of its width. In this embodiment, the lifting assembly 43 is configured as a plurality of electrically operated telescopic rods, which are fixedly installed on the side wall of the cooling pool 2, and the piston rods extend vertically upward and are fixedly connected to one end of the lifting frame 421 that extends out of the cooling pool 2, so as to drive the sliding of the lifting frame 421.

[0038] Reference Figure 2 Each lifting frame 421 has a mounting portion 4211 at its midpoint along its length, and the mounting portion 4211 is integrally formed with the main body of the lifting frame 421. Sliding frames 422 are located on opposite sides of the mounting portions 4211 and are slidably connected to the lifting frame 421 via slide rails, with the sliding direction being the length direction of the lifting frame 421. Each sliding frame 422 is slidably connected to the inner wall of the cooling pool 2 via a slide rail or slide groove. The top of the sliding path of the sliding frame 422 is vertically positioned, and the bottom gradually slopes downwards, extending towards both ends of the cooling pool 2, so that the two sliding frames 422 gradually move away from each other as the lifting frame 421 slides downwards.

[0039] Reference Figure 2 In this embodiment, each sliding frame 422 is equipped with a roller, which is rotatably connected to the corresponding sliding frame 422 via a pin and is embedded in the corresponding slide rail or groove to reduce wear on the sliding frame 422. The setting part 4211 and each sliding frame 422 are each equipped with two guide rollers 44. The axis of the guide rollers 44 is in the width direction of the cooling pool 2, and both ends of each guide roller 44 are rotatably connected to the corresponding setting part 4211 or sliding frame 422 via bearings. Furthermore, the two guide rollers 44 on the setting part 4211 and each sliding frame 422 are distributed vertically to allow the rubber strip to pass through the gap in the middle.

[0040] Reference Figure 2 The number of upper mounting brackets 41 is set to two, and the two upper mounting brackets 41 are arranged in a one-to-one correspondence with the two sliding brackets 422. In the horizontal direction, each upper mounting bracket 41 is located between the corresponding sliding bracket 422 and the mounting part 4211. Each upper mounting bracket 41 is slidably connected to the inner side wall of the cooling pool 2 through a slide rail, and the sliding direction is set to the length direction of the cooling pool 2.

[0041] Reference Figure 2 The guide mechanism 4 also includes a linkage component 45, which includes two linkage frames 451, each corresponding to one of the two upper mounting frames 41. One end of each linkage frame 451 is rotatably connected to the top of the lifting frame 421 via a pin, and the other end is inclined downwards and rotatably connected to the corresponding upper mounting frame 41 via a pin.

[0042] Reference Figure 2 Each upper mounting frame 41 is equipped with two guide rollers 44, the axis of which is in the width direction of the cooling pool 2. Both ends of each guide roller 44 are rotatably connected to the corresponding upper mounting frame 41 via bearings. The two guide rollers 44 are distributed vertically to allow the rubber strip to pass through the middle. When the upper mounting frame 41 and the sliding frame 422 are close together, the tops of the guide rollers 44 on the upper mounting frame 41 and the guide rollers 44 on the mounting part 4211 and the sliding frame 422 are flush.

[0043] Reference Figure 1 and Figure 2 A guide plate 46 is provided on the upper frame 41 near the melt extrusion mechanism 1. The guide plate 46 is located on the side of the frame near the melt extrusion mechanism 1 and is fixedly connected to the upper frame. The top wall of the guide plate 46 is flush with the top of the guide roller 44 so that the rubber strip moves to the guide roller 44 via the pouring plate.

[0044] Reference Figure 1 and Figure 2 In the initial state, when the sliding frame 422 is close to the upper mounting frame 41, the upper mounting frame 41 is located on the side of its sliding trajectory closest to the mounting part 4211. At this time, the lifting frame 421 is located at the top of its sliding trajectory. Several guide rollers 44 are close together and their top ends are flush to allow the rubber strip to pass through. After the rubber strip passes through the upper mounting frame 41 on the side away from the melt extrusion mechanism 1, the lifting assembly 43 drives the lifting frame 421 to descend.

[0045] Reference Figure 1 and Figure 2During this process, the sliding frame 422 slides downwards, and after its top height is lower than the bottom of the upper mounting frame 41 (i.e., completely below the upper mounting frame 41), the rollers on the sliding frame 422 move to the inclined portion of the corresponding slide rail or slide groove, thereby causing the two sliding frames 422 to slide relative to the lifting frame 421 and move away from each other. During this process, the lifting frame 421 drives the corresponding upper mounting frame 41 to slide through the linkage frame 451, causing each upper mounting frame 41 to slide relative to the cooling pool 2 and move away from each other, thereby increasing the distance between the upper mounting frame 41, the sliding frame 422, and the mounting part 4211, making the rubber strips meander and evenly distributed.

[0046] Reference Figure 1 , Figure 2 and Figure 3 The cooling pool 2 is also equipped with a conveying mechanism 5, which includes a conveying frame 51, a clamping assembly 52, a driving assembly 53, and a conveying guide rail 54. In this embodiment, two conveying guide rails 54 are provided, located on both sides of the cooling pool 2 along its width direction, and both are fixedly installed on the cooling pool 2. The distance between the two conveying frames 51 is less than the length of the guide roller 44 to reduce the probability of interference between the conveying frame 51 and the lifting frame 421. One end of each conveying guide rail 54 is located on the side of the cooling pool 2 away from the melt extrusion mechanism 1, and the other end extends towards the other end of the cooling pool 2. After reaching the inclined section at the end of the cooling pool 2, each rail extends downward along the inclined direction and, after reaching a height similar to that of the guide roller 44, extends towards the nearest guide roller 44.

[0047] Reference Figure 2 and Figure 3 The number of conveyor frames 51 is set to two, corresponding to two conveyor rails 54. Each conveyor frame 51 is provided with a plurality of guide wheels 55. In this embodiment, the number of guide wheels 55 is set to two, and both are rotatably connected to the conveyor frame 51 by pins. Each guide wheel 55 is embedded in the corresponding conveyor rail 54 and abuts against the inner wall of the corresponding conveyor rail 54.

[0048] Reference Figure 2 and Figure 3 The number of drive components 53 is set to two, and they correspond to the two conveying guide rails 54. In this embodiment, each drive component 53 is a combination structure of a servo motor, a belt and pulleys. The number of pulleys is set to several, and they correspond to the bends of the conveying guide rails 54. Each pulley is rotatably connected to the cooling pool 2 through a pin. The belt is sleeved on several pulleys so that the displacement path of the belt is the extension direction of the conveying guide rails 54.

[0049] Reference Figure 2and Figure 3 The aforementioned servo motor is fixedly installed at the end of the cooling pool 2 and is used to drive one of its pulleys to rotate. The aforementioned belt is fixedly connected to the conveyor frame 51 so that the belt can drive the conveyor frame 51 to slide along the extension direction of the conveyor guide rail 54 during movement.

[0050] Reference Figure 2 and Figure 3 The clamping assembly 52 includes clamping plates 521 and clamping elements 522. Two clamping plates 521 are provided, and each clamping plate 521 has two ends along its length corresponding to two conveyor frames 51. One end of each clamping plate 521 along its length is rotatably connected to the corresponding conveyor frame 51 via a pin. Each clamping plate 521 has clamping elements 522 at both ends along its length.

[0051] Reference Figure 2 and Figure 3 Each clamping component 522 includes a transmission frame 5221 and a drive frame 5222. One end of each transmission frame 5221 is rotatably connected to the middle of the corresponding clamping plate 521 via a pin, and the other end is rotatably connected to the corresponding drive frame 5222 via a pin. Each drive frame 5222 is slidably connected to the corresponding conveyor frame 51 via a slide rail, and the sliding direction is perpendicular to the moving direction of the conveyor frame 51.

[0052] Reference Figure 2 and Figure 3 The cooling pool 2 is also equipped with two driving components 56, each corresponding to a conveying guide rail 54. Each driving component 56 includes a driving slide rail 561, which is annular and is integrally formed with the corresponding conveying guide rail 54, with two driving grooves 5611 on each of the upper and lower sides of the corresponding conveying guide rail 54.

[0053] Reference Figure 2 and Figure 3 Each drive slot 5611 is correspondingly provided with a drive frame 5222. Each drive slot 5611 extends along the extension direction of the conveying guide rail 54, and both ends of each drive slot 5611 are inclined away from the drive slide rail 561. One end of each drive frame 5222 extends into the corresponding drive slot 5611 and abuts against the inner wall of the corresponding drive slot 5611.

[0054] Reference Figure 2 and Figure 3In the initial state, the conveyor frame 51 is located on the side of its sliding path closer to the sliding frame 422. At this time, the extension end of the drive frame 5222 on the conveyor frame 51 is located in the inclined part of the drive groove 5611, and the two clamping plates 521 are in the open state. When the adhesive strip moves between the two clamping plates 521 via the guide wheel 55, the drive assembly 53 drives the conveyor frame 51 away from the sliding frame 422, so that the inner wall of the drive groove 5611 abuts against the extension part of the drive frame 5222, pushing the drive frame 5222 to slide. This causes the drive frame 5222 to drive the clamping plate 521 to rotate through the transmission frame 5221, so that the clamping plate 521 clamps and fixes the end of the adhesive strip.

[0055] Reference Figure 1 , Figure 2 and Figure 3 Subsequently, when the sliding frame 422, the lifting frame 421 and the upper setting frame 41 slide together and the rubber strips are evenly distributed, the drive assembly 53 gradually drives the conveyor frame 51 away from the cooling pool 2. During this process, the clamping plate 521 on the conveyor frame 51 continuously clamps the rubber strips and drives the rubber strips to gradually approach the pelletizing mechanism 3.

[0056] Reference Figure 1 In this embodiment, the pelletizing mechanism 3 is configured as a pelletizer. The pelletizer is equipped with a cutter and a cylinder that drives the cutter to move up and down. After the cylinder drives the cutter to slide downward, the cutter can cut the cooled rubber strip into uniform pellets. This pelletizer is prior art and will not be described in detail here.

[0057] Reference Figure 1 and Figure 4 The pelletizer is equipped with a moving mechanism 6 on the side near the cooling tank 2. The moving mechanism 6 includes two moving frames 61 and a moving assembly 62. The two moving frames 61 are located on the upper and lower sides of the rubber strip, respectively, and are slidably connected to the pelletizer, with both sliding in a vertical direction. Each moving frame 61 is equipped with a conveying roller 63 and a rotating motor 64. The rotating motor 64 is fixedly mounted on the moving frame 61, and its output shaft is fixedly connected to one end of the conveying roller 63 via a coupling. Both ends of the conveying roller 63 are rotatably connected to the moving frame 61 via pins.

[0058] Reference Figure 1 and Figure 4The moving assembly 62 includes a moving component 621, a displacement frame 622, and two reversing frames 623. In this embodiment, the moving component 621 is an electric telescopic rod. This electric telescopic rod is fixedly installed on the pelletizer, and its piston rod is fixedly connected to the displacement frame 622 by bolts. The displacement frame 622 is slidably connected to the pelletizer via a slide rail. The reversing frames 623 are arranged in a one-to-one correspondence with the moving frames 61, with one end rotatably connected to the corresponding moving frame 61 via a pin, and the other end rotatably connected to the displacement frame 622 via a pin.

[0059] Reference Figure 1 and Figure 4 When the conveyor frame 51 approaches the conveyor roller 63 on the movable frame 61, the movable component 621 drives the displacement frame 622 to slide, thereby causing the two reversing frames 623 to drive the movable frame 61 to slide, so that the conveyor roller 63 moves away from each other and avoids the conveyor frame 51. When the conveyor frame 51 moves to the side where the conveyor roller 63 is away from the cooling pool 2, the drive component 53 drives the movable frame 61 to return to the initial position, so that the conveyor roller 63 conveys the rubber strip. At this time, the drive frame 5222 on the conveyor frame 51 gradually abuts against the inclined inner wall of the corresponding drive groove 5611, thereby causing the drive frame 5222 to slide, and driving the clamping plate 521 to rotate through the transmission frame 5221, thus canceling the clamping of the rubber strip.

[0060] The implementation principle of a cooling granulator for hot melt adhesive film production according to an embodiment of this application is as follows: When the melt extrusion mechanism 1 begins to extrude the adhesive strip, after the adhesive strip passes through the upper mounting frame 41 on the side away from the melt extrusion mechanism 1, the lifting assembly 43 drives the lifting frame 421 to descend. During this process, the sliding frame 422 slides downward, and after its top height is lower than the bottom of the upper mounting frame 41 (i.e., completely below the upper mounting frame 41), the rollers on the sliding frame 422 move to the inclined part of the corresponding slide rail or slide groove, thereby causing the two sliding frames 422 to slide relative to the lifting frame 421 and move away from each other. During this process, the lifting frame 421 drives the corresponding upper mounting frame 41 to slide through the linkage frame 451, and causes each upper mounting frame 41 to slide relative to the cooling pool 2 and move away from each other, thereby increasing the distance between the upper mounting frame 41, the sliding frame 422 and the mounting part 4211, making the adhesive strip meander and uniformly distributed.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
