Description

Technical Field

[0001] The utility model relates to the technical field of extrusion dies, and more specifically, to an automatic rubber cutting machine. Background Art

[0002] During the welding and assembly process of the vehicle body, there are often some gaps between sheet metal parts. The existence of these gaps will result in poor waterproof and sound insulation performance of the whole vehicle, and this situation will become more serious as the service life of the vehicle increases, affecting the use safety of the vehicle. Therefore, during the current vehicle production process, finger pressure sealant is used to fill the gaps to improve the overall waterproof and sound insulation performance. During the production process of the finger pressure sealant, a rubber cutting machine is needed to cut the colloid.

[0003] There is a Chinese utility model with the publication number CN218084041U, which discloses a finger pressure glue forming device, including a preforming device provided with a plurality of extrusion ports and a shearing device that can reciprocate in a direction intersecting the axis of the extrusion port. The shearing device is arranged on the extrusion side of the extrusion port. This utility model improves the production efficiency of finger pressure glue and the adaptability to vehicle models by integrating the shearing device and the preforming device.

[0004] However, in the above technical solution, since the extrusion ports are fixed, the diameter of the glue outlet holes on the rubber cutting machine cannot be adjusted according to the required diameter of the colloid, reducing the flexibility of the rubber cutting machine during use. Summary of the Utility Model

[0005] To solve the above problems, the utility model provides an automatic rubber cutting machine, which adjusts the diameter of the glue outlet by changing the relative position between the glue outlet plate and the adjustment plate, and then changing the size of the holes through which the glue can flow between the glue outlet holes and the connection holes.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is: an automatic rubber cutting machine, including a machine body, a glue tank with openings at both ends is arranged on the machine body, a glue pushing device is arranged at one end of the glue tank, a glue outlet device is arranged at the other end of the glue tank, a cutting device is arranged at the end of the glue outlet device away from the glue tank, the glue outlet device includes a glue outlet plate, a plurality of glue outlet holes are opened on the glue outlet plate, a slot is arranged in the glue outlet plate, an adjustment plate is slidably connected in the slot, a plurality of adjustment holes are arranged on the adjustment plate, and the positions of the adjustment holes correspond to the positions of the glue outlet holes.

[0007] In this technical solution, the glue tank, the glue pushing device, the glue discharging device, and the glue cutting device are all installed on the machine body, and the colloid is stored in the glue tank. When making sealant, start the glue pushing device at one end of the glue tank. The glue pushing device continuously compresses the volume in the glue tank to extrude the colloid, so that the colloid is continuously extruded from the glue outlet. A glue discharging device is arranged at the glue outlet. The glue discharging device includes a glue discharging plate, and glue discharging holes are arranged on the glue discharging plate. The colloid is extruded from the glue tank through the glue discharging holes, and the extruded colloid is in a strip shape. The extruded colloid is cut by the glue cutting device according to the required length, and finally the required finger pressure sealant is made. When the colloid is extruded from the glue tank, the shape of the colloid is the same as that of the glue discharging holes. Therefore, by changing the shape of the glue discharging holes, the diameter of the extruded colloid can be changed, so as to adapt to the production requirements of finger pressure sealants with different diameters and improve the versatility of the equipment. A slot is arranged in the middle of the glue discharging plate, and an adjusting plate is slidably connected in the slot. A plurality of adjusting holes are arranged on the adjusting plate, and the positions of the adjusting holes correspond to the positions of the glue discharging holes on the glue discharging plate. When extruding the basic colloid, the colloid needs to pass through the adjusting plate and the glue discharging plate in sequence, and can only be extruded from the glue discharging holes and the adjusting holes. Therefore, the shape of the extruded colloid is jointly determined by the glue discharging holes and the adjusting holes, and the overlapping part of the glue discharging holes and the adjusting holes is the shape of the cross section of the extruded colloid. When the glue discharging holes and the adjusting holes are completely aligned, the overlapping part reaches the maximum, and the diameter of the cross section of the extruded colloid also reaches the maximum. When the adjusting plate is pulled, the adjusting plate slides in the slot, the relative position between the adjusting plate and the glue discharging plate changes, the relative position between the adjusting holes on the adjusting plate and the glue discharging holes on the glue discharging plate changes, the adjusting holes and the glue discharging holes are no longer in an aligned relationship, the overlapping part of the adjusting holes and the glue discharging holes becomes smaller, the area through which the colloid can pass becomes smaller, and finally the diameter of the cross section of the extruded colloid becomes smaller, achieving the function of adjusting the glue discharging diameter.

[0025] The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the attached drawings:

[0026] Embodiment 1

[0027] As Figure 1 、 2, as shown in Figures 3, an automatic glue cutting machine includes a machine body 1. There is a glue tank 2 with openings at both ends on the machine body 1. A glue pushing device 3 is arranged at one end of the glue tank 2, and a glue discharging device 4 is arranged at the other end of the glue tank 2. A glue cutting device 5 is arranged at the end of the glue discharging device 4 away from the glue tank 2. The glue discharging device 4 includes a glue discharging plate 41. A plurality of glue discharging holes 42 are formed on the glue discharging plate 41. A slot 43 is arranged in the glue discharging plate 41. A regulating plate 44 is slidably connected in the slot 43. A plurality of regulating holes 45 are arranged on the regulating plate 44. The positions of the regulating holes 45 correspond to the positions of the glue discharging holes 42. When making sealant, start the glue pushing device 3 at one end of the glue tank 2. The glue pushing device 3 continuously compresses the volume in the glue tank 2 to extrude the glue, so that the glue is continuously extruded from the glue discharging port. There is a glue discharging device 4 at the glue discharging port. The glue discharging device 4 includes a glue discharging plate 41. The glue discharging plate 41 is provided with glue discharging holes 42. The glue is extruded from the glue tank 2 through the glue discharging holes 42, and the extruded glue is in a strip shape. The extruded glue is cut by the glue cutting device according to the required length, and finally the required finger pressure sealant is made. When the glue is extruded from the glue tank 2, the shape of the glue is the same as the shape of the glue discharging holes 42. Therefore, the diameter of the extruded glue can be changed by changing the shape of the glue discharging holes 42, so as to adapt to the production requirements of finger pressure sealants with different diameters and improve the versatility of the equipment. There is a slot 43 in the middle of the glue discharging plate 41. A regulating plate 44 is slidably connected in the slot 43. A plurality of regulating holes 45 are arranged on the regulating plate 44. The positions of the regulating holes 45 correspond to the positions of the glue discharging holes 42 on the glue discharging plate 41. When extruding the basic glue, the glue needs to pass through the regulating plate 44 and the glue discharging plate 41 in sequence, and can only be extruded from the glue discharging holes 42 and the regulating holes 45. Therefore, the shape of the extruded glue is jointly determined by the glue discharging holes 42 and the regulating holes 45. The overlapping part of the glue discharging holes 42 and the regulating holes 45 is the shape of the cross-section of the extruded glue. When the glue discharging holes 42 and the regulating holes 45 are completely aligned, the overlapping part reaches the maximum, and the diameter of the cross-section of the extruded glue also reaches the maximum. When the regulating plate 44 is pulled, the regulating plate 44 slides in the slot 43, and the relative position between the regulating plate 44 and the glue discharging plate 41 changes. The relative positions of the regulating holes 45 on the regulating plate 44 and the glue discharging holes 42 on the glue discharging plate 41 change. The regulating holes 45 and the glue discharging holes 42 are no longer in an aligned relationship, and the overlapping part of the regulating holes 45 and the glue discharging holes 42 becomes smaller, so that the area through which the glue can pass becomes smaller, and finally the diameter of the cross-section of the extruded glue becomes smaller, achieving the effect of adjusting the glue discharging diameter.

[0028] As Figure 2As shown, a threaded rod 46 is provided at one end of the notch of the slot 43 where the adjusting plate 44 is located. The adjusting plate 44 is rotatably connected to the threaded rod 46, and the threaded rod 46 is threadedly connected to the glue discharging plate 41. The threaded rod 46 is installed on the adjusting plate 44 and can only rotate without relative movement with the adjusting plate 44. The threaded rod 46 is inserted into the glue discharging plate 41 and threadedly connected to the glue discharging plate 41. When the threaded rod 46 rotates, the glue discharging plate 41 remains fixed, and the threaded rod 46 extends or inserts into the glue discharging plate 41 along the thread, thereby driving the adjusting plate 44 to slide in the slot 43, changing the relative position between the adjusting hole 45 and the glue discharging hole 42, and thus realizing the change of the glue discharging diameter. At the same time, since changing the position of the threaded rod 46 requires rotating the threaded rod 46, the direction of the force received by the threaded rod 26 is constantly changing during this process. If the adjusting plate 46 slides in the slot 43, it needs to receive a force in the direction of the slot 43, and the direction of this force is constant and cannot drive the threaded rod 46 to rotate. Since the threaded rod 46 is rotatably connected to the adjusting plate 4, and the threaded rod 46 cannot move, the adjusting plate 4 cannot move either. Therefore, unless under manual control, the adjusting plate 44 threadedly connected to the glue discharging plate 41 through the threaded rod 46 will not move relative to the glue discharging plate 41, ensuring that the adjusting plate 44 will not accidentally move during the glue discharging process, resulting in a glue discharging diameter that does not meet the requirements.

[0029] As Figure 2 shown, a guide rod 47 is further provided at one end of the notch of the slot 43 where the adjusting plate 44 is located. The guide rod 47 is parallel to the threaded rod 46. The adjusting plate 44 is fixedly connected to the guide rod 47, and the guide rod 47 is slidably connected to the glue discharging plate 41. The guide rod 47 can cooperate with the threaded rod 46 to ensure that the adjusting plate 44 will not shift during the movement. At the same time, the guide rod 47 is slidably connected to the glue discharging plate 41 and will not affect the sliding of the adjusting plate 44 in the slot 43.

[0030] As Figure 1As shown in the figure, the rubber cutting device 5 includes a rubber cutting knife 51 and a driving member 52. The driving member 52 is installed on the machine body 1. The back surface of the rubber cutting knife 51 is attached to the surface of the glue discharging plate 41. The rubber cutting knife 51 is slidably connected to the glue discharging plate 41, and one end of the rubber cutting knife 51 is connected to the driving end of the driving member 52. The driving member 52 can drive the rubber cutting knife 51 to reciprocate. After the colloid is extruded from the glue discharging device 4, the driving member 52 is started, and the driving member 52 can drive the rubber cutting knife 51 to reciprocate. The rubber cutting knife 51 continuously cuts the extruded colloid into appropriate lengths, and finally the product is obtained. The back surface of the rubber cutting knife 51 is attached to the surface of the glue discharging plate 41. On the one hand, the glue discharging plate 41 plays a supporting role for the rubber cutting knife 51, making it difficult for the rubber cutting plate 51 to tilt towards or away from the glue discharging plate 51, ensuring the accuracy of the rubber cutting position. On the other hand, since the colloid is relatively soft, the rubber cutting knife 51 is likely to cause the colloid to bend and deform during the cutting process, resulting in defective products. By making the rubber cutting knife 51 adhere to the glue discharging plate 41, the glue discharging plate 41 plays a certain supporting role for the colloid, making it difficult for the colloid to deform during the cutting process. The working speed of the driving member 52 can be adjusted. During use, the cutting frequency of the rubber cutting knife 51 can be adjusted by adjusting the speed of the driving member 52 to cut colloids of different lengths.

[0031] As Figure 1 , 2 shown in the figure, it further includes a limiting plate 53. There are two limiting plates 53, which are respectively installed at the upper and lower ends of the glue discharging plate 41. The two limiting plates 53 are respectively slidably connected to the upper and lower side surfaces of the rubber cutting knife 51. The limiting plate 53 is used to limit the movement track of the rubber cutting knife 51 to prevent the rubber cutting knife 51 from shifting upward or downward due to uneven force during rubber cutting.

[0032] Embodiment 2

[0033] This embodiment is similar to the above-mentioned Embodiment 1. The difference is that, as Figure 4 shown in the figure, the glue pushing device 3 includes a second driving member 31 and a glue pushing plate 32. The glue pushing plate 32 is installed in the glue tank 2. The outer peripheral surface of the glue pushing plate 32 is slidably connected to the inner wall surface of the glue tank 2. The second driving member 31 is installed on the machine body 1. The driving end of the second driving member 31 extends into the glue tank 2 through an opening and is connected to the glue pushing plate 32. The colloid is placed in the space between the glue pushing plate 32 and the glue discharging device 4 in the glue tank 2. When discharging glue, the second driving member 32 is started, and the second driving member 32 drives the glue pushing plate 32 to move towards the direction of the glue discharging device 4. The space between the glue pushing plate 32 and the glue discharging device 4 becomes smaller, and since the volume of the colloid is difficult to compress, the excess colloid is extruded from the glue discharging device 4. The glue discharging speed can be achieved by adjusting the driving speed of the second driving member 31. The second driving member 31 can cooperate with the driving member to adjust different production speeds and cut colloids of different lengths.

[0034] As Figure 4As shown, a sealing gasket 33 is further provided on the outer peripheral surface of the glue pushing plate 32, and the sealing gasket 33 is slidably connected to the outer wall surface of the glue tank 2. By providing the sealing gasket 33, the sealing performance between the glue pushing plate 32 and the glue tank 2 is enhanced, ensuring that no glue leaks during the glue pushing process.

[0035] Embodiment 3

[0036] This embodiment is similar to the above-mentioned Embodiment 1, except that, as Figure 1 shown, the glue tank 2 is further connected with a glue supply pipe 6, and a valve 7 is provided on the glue supply pipe 6. The glue supply pipe 6 can timely supply glue to the glue tank 2, and a valve 7 is also provided on the glue supply pipe 6. When pushing the glue, the valve 7 is closed, which can avoid the reverse overflow of the glue into the glue supply pipe 6 and cause damage to the glue supply pipe 6.

[0037] As Figure 1 shown, a cover plate 8 is detachably mounted on the upper surface of the glue tank 2. The user can observe the working conditions inside the glue tank 2 and clean the inside of the glue tank 2 by removing the cover plate 8.

[0038] As Figure 1 shown, a material receiving plate 9 is further provided at one end of the machine body 1 close to the glue cutting device 5. The material receiving plate 9 is used to place the released glue.

[0039] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here.
