Detailed Embodiment

[0027] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1 - 4 , the present utility model provides a technical solution:

[0029] As Figures 1 - 4As shown in the figure, a flash trimming device for rubber sealing strips is used for trimming the rubber sealing strip 1. The rubber sealing strip 1 includes a bottom plate 12 and side plates 11 on both sides of the bottom plate 12. The device includes a frame 2 and a feeding assembly 3, a limiting assembly, a grinding assembly 7 and a coiling assembly 6 located inside the frame 2. The feeding assembly 3 includes a feeding belt and a guiding assembly located above the feeding belt. The rubber sealing strip 1 is located between the feeding belt and the guiding assembly.

[0030] The limiting assembly includes a lower die 5 and an upper die 4. The lower die 5 and the upper die 4 form a cavity through which the rubber sealing strip 1 passes.

[0031] The grinding assembly 7 is located above the rubber sealing strip 1. The grinding assembly 7 includes a driving motor 71 and a grinding head 72.

[0032] The coiling assembly 6 includes a turntable 61 and a support 62. The rubber sealing strip 1 is recycled after being rotated by the turntable 61.

[0033] Through the above technical solution, the rubber sealing strip 1 is placed between the guiding assembly and the feeding belt. The rubber sealing strip 1 is restricted above the feeding belt through the guiding assembly. Due to the friction between the feeding belt and the rubber sealing strip 1, the feeding belt rotates to drive the rubber sealing strip 1 to move.

[0034] When the rubber sealing strip 1 approaches the limiting assembly, the rubber sealing strip 1 is aligned with the cavity formed by the upper die 4 and the lower die 5. The posture of the rubber sealing strip 1 after passing through is restricted by the upper die 4 and the lower die 5. When the side plates 11 face upwards after the rubber sealing strip 1 passes through the limiting assembly, the driving motor 71 drives the grinding head 72 to rotate at this time, and the top of the side plates 11 can be ground.

[0035] The rubber sealing strip 1 after grinding is recycled through the coiling assembly 6. The whole grinding process is convenient to operate, reduces manpower, and improves the grinding effect and efficiency.

[0036] Further, the lower die 5 is of a U-shaped groove structure. The length of the lower die 5 is greater than the length of the upper die 4. The lower die 5 includes a first limiting portion 51 and second limiting portions 52 on both sides of the first limiting portion 51. The distance between the two second limiting portions 52 is adapted to the width of the bottom plate 12. The height of the second limiting portion 52 is lower than the height of the side plate 11.

[0037] The upper die 4 includes a set of third limiting parts 41 and fourth limiting parts 42 which are symmetrically arranged. The width of the third limiting part 41 is the same as that of the second limiting part 52. The third limiting part 41 is located above the second limiting part 52. The distance between the third limiting part 41 and the adjacent fourth limiting part 42 is equal to the width of the side plate 11. The side plate 11 is located between the third limiting part 41 and the fourth limiting part 42. The highest point of the groove between the third limiting part 41 and the adjacent fourth limiting part 42 is higher than the highest point of the side plate 11.

[0038] Through the above technical solution, the first limiting part 51, the second limiting part 52, the third limiting part 41 and the fourth limiting part 42 form a limiting space through which the rubber sealing strip 1 passes. After the rubber sealing strip 1 passes through the limiting component, the bottom plate 12 faces downward and the side plate 11 faces upward, which is convenient for the subsequent grinding component 7 to perform grinding. At the same time, the limiting component can prevent the rubber sealing strip 1 from shifting, so that the rubber sealing strip 1 is always below the grinding component 7.

[0039] Further, a pressing wheel assembly is provided between the two fourth limiting parts 42. The pressing wheel assembly includes a connecting column 46, a wheel seat 45 and a roller 44 located in the wheel seat 45. The roller 44 is located on the bottom plate 12. One end of the connecting column 46 is fixed to the upper die 4, and the other end of the connecting column 46 is slidably connected to the wheel seat 45. A limiting nut 43 is provided below the connecting column 46 in the wheel seat 45. A spring 47 is sleeved on the connecting column 46, and the spring 47 is located above the wheel seat 45.

[0040] Through the above technical solution, when the rubber sealing strip 1 does not extend into the limiting component, the roller 44 is driven by the elastic force of the spring 47 to press on the second limiting part 52. When the rubber sealing strip 1 extends into the limiting component, at this time, the bottom plate 12 is inserted between the roller 44 and the second limiting part 52, and the roller 44 drives the wheel seat 45 to compress the spring 47 and move upward. Under the elastic force of the spring 47, the roller 44 presses the bottom plate 12 of the rubber sealing strip 1 against the second limiting part 52. After one side of the rubber sealing strip 1 extends out of the upper die 4, the rubber sealing strip 1 will not warp upward, so that the grinding head 72 can contact the top of the side plate 11, improving the grinding effect.

[0041] Further, the grinding component 7 is located on one side of the upper die 4 and above the lower die 5. An adjusting component is provided above the driving motor 71. The adjusting component includes an upper plate 73 and a lower plate 74. One side of the upper plate 73 is fixed to the frame 2. The lower plate 74 is located below the upper plate 73. The motor seat of the driving motor 71 is fixed below the lower plate 74. The lower plate 74 and the upper plate 73 are connected by a bolt assembly. The diameter of the grinding head 72 is larger than the width of the rubber sealing strip 1.

[0042] Through the above technical solution, since the lower die 5 is longer than the upper die 4, when the rubber sealing strip 1 extends out of the upper die 4, it is still within the lower die 5. The first limiting portion 51 and the second limiting portion 52 are used to limit the rubber sealing strip 1. Since the side plate 11 is higher than the first limiting portion 51, the grinding head 72 can directly grind the flash on the side plate 11 without interfering with the first limiting portion 51. By adjusting the distance between the lower plate 74 and the upper plate 73, the height of the grinding head 72 can be adjusted, and thus the grinding depth can be adjusted to improve the grinding effect.

[0043] Furthermore, the feeding belt is connected to the frame 2. The feeding belt includes a belt assembly and a support plate 34, an adjusting cylinder 35, and a tensioning cylinder 36 located within the belt assembly. One end of the support plate 34 is connected to the frame 2, and the cylinder bases of multiple adjusting cylinders 35 are fixed to the side of the support plate 34 close to the rubber sealing strip 1; the cylinder base of the tensioning cylinder 36 is fixed to the side of the support plate 34 away from the rubber sealing strip 1.

[0044] Furthermore, abutting plates 37 are provided at the ends of the piston rods of the adjusting cylinder 35 and the tensioning cylinder 36, and one side of the abutting plate 37 abuts against the inner side of the belt within the belt assembly.

[0045] Furthermore, balls are provided on the side of the abutting plate 37 close to the inner side of the belt.

[0046] Through the above technical solution, the friction between the belt drive assembly 33 and the rubber sealing strip 1 drives the rubber sealing strip 1 to feed. The adjusting cylinder 35 is used to drive the abutting plate 37 to abut against the inner side of the belt to increase the contact area between the outer side of the belt and the rubber sealing strip 1. At the same time, the rubber sealing strip 1 can be pressed against the guiding assembly through the adjusting cylinder 35 to prevent slipping. At the same time, when the adjusting cylinder 35 drives the belt to move, the tensioning cylinder 36 makes an adaptive adjustment so that the belt always remains in a taut state to prevent the belt from slipping. At the same time, the balls between the abutting plate 37 and the belt can reduce friction and improve the transmission effect of the belt.

[0047] Furthermore, the guiding assembly includes a mounting plate 31 and a guiding wheel 32 located below the mounting plate 31. One side of the mounting plate 31 is fixed to the frame 2, and the guiding wheel 32 is located above the rubber sealing strip 1.

[0048] Through the above technical solution, the guiding wheel 32 can rotate freely. The guiding wheel 32 can be a V-shaped wheel, and the rubber sealing strip 1 can be stuck in the guiding wheel 32 to prevent deviation.

[0049] Furthermore, the turntable 61 is rotatably connected to the support 62, and a rotating motor is provided outside the turntable 61.

[0050] Through the above technical solution, the turntable 61 is driven to rotate by a rotating motor, and thus the automatic coiling and recycling of the rubber sealing strip 1 can be completed.

[0051] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. Any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
