Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 7 , in the embodiment of the present utility model, a seat sponge trimming machine includes a support frame 1. On one side of the support frame 1, there are two support legs 2. Between the two support legs 2 and the support frame 1, there are fixed connection tracks 3. On the length direction of the two tracks 3, a placement table 4 is slidably connected through a sliding seat assembly 10; on the top of the placement table 4, there is a cutting slot 401 that penetrates the bottom. At one end of the top of the placement table 4, a baffle 5 is slidably arranged. Between the baffle 5 and the placement table 4, there is an adjustment component 6 for regulating the distance between the baffle 5 and the cutting slot 401; at one end of the placement table 4, there is a cutting component 7 for trimming the sponge. The cutting component 7 includes a housing 701. The housing 701 is in a "C" - shaped structure, and the placement table 4 is located in the middle of the housing 701. In the lower inner cavity of the housing 701, a first synchronous wheel 702 is rotatably connected. In the upper inner cavity of the housing 701, there is a second synchronous wheel 703. Between the first synchronous wheel

[0026] 702 and the second synchronous wheel 703, there is an annular cutter 704. On one side of the housing 701, there is a cutting motor 705 for driving the first synchronous wheel 702 to rotate; the annular cutter 704 is in an annular belt - like structure, and one end of the annular cutter 704 is located inside the cutting slot 401.

[0027] The slide assembly 10 includes a base body 101 fixedly connected to the bottom of the placement table 4, and a first roller 102 that rolls along the length direction of the top end of the track 3 is installed in the middle of the base body 101. Two groups of second rollers 103 that roll along the length direction of the two side walls of the track 3 are symmetrically provided at both ends of the base body 101.

[0028] In this embodiment, by pulling the placement table 4 to move along the length of the track 3, the annular cutter 704 and the cutting slit 401 can be moved horizontally relative to each other, thereby trimming and cutting the sponge placed on the placement table 4. In addition, the adjustment component 6 is used to adjust the distance between the baffle 5 and the cutting slit 401. This distance is the size of the sponge block that needs to be trimmed. First, one end of the sponge block is placed against the baffle 5, and then the adjustment component 6 is used to adjust the horizontal movement of the baffle 5 to achieve the required trimming and cutting size. When in use, first pull the placement table 4 away from the annular cutter 704, then press the sponge with one hand to fix it on the surface of the placement table 4 with one end against the baffle 5, and then use the other hand to pull the placement table 4 to move the sponge close to and pass through the annular cutter 704, thereby completing the linear trimming and cutting of the sponge block.

[0029] Please refer to Figures 1 to 7 The adjustment component 6 includes two racks 601, which are symmetrically distributed on both sides of the baffle 5, and the two racks 601 are fixed at both ends of the top of the placement table 4. Two sliding rods 602 are symmetrically provided on the two side walls of one end of the placement table 4. The two sliding rods 602 are slidably equipped with displacement seats 603 in the length direction. The middle part of the displacement seat 603 is rotatably connected to the shaft 604, one end of the shaft 604 is connected to a gear 605, and the other end of one of the shafts 604 is connected to a handwheel 606; the baffle 5 is located between the two displacement seats 603, and the displacement seat 603 is fixedly connected to the baffle 5; the gear 605 is meshed with the rack 601.

[0030] The adjustment assembly 6 also includes a first locking assembly for limiting the rotation of the shaft 604. The first locking assembly includes a first fixed block 607 fixedly connected to one end of the baffle 5. The middle part of the first fixed block 607 is threadedly connected to a first screw rod 608. The lower end of the first screw rod 608 is rotatably connected to a first extrusion block 609. The bottom end surface of the first extrusion block 609 is adapted to the outer surface contour of the shaft 604. The bottom end surface of the first extrusion block 609 and the middle outer wall of the shaft 604 are both rough surfaces.

[0031] In this embodiment, the cutting slit 401 divides the placement platform 4 into two areas: the left end is the placement area for the sponge body, and the right end is the material removal area. The adjustment assembly 6 is installed in the material removal area on the right end of the placement platform 4. By turning the handwheel 606, the gear 605 is forced to rotate. Since the gear 605 is engaged with the rack 601, when the gear 605 rotates, it will drive the displacement seat 603 to move along the length of the slide bar 602, thereby changing the distance between the baffle 5 and the cutting slit 401. To facilitate observation of the movement distance, a ruler can be provided on the side of the material removal area on the right end of the placement platform 4 to determine the movement distance of the baffle 5 in real time.

[0032] Please refer to Figures 1 to 7 Two groups of grinding components 8 are installed at the bottom of the placement table 4. The two groups of grinding components 8 are distributed on both sides of one end of the annular cutter 704 and are used to grind the outer wall of the annular cutter 704; the grinding component 8 includes a fixed seat 801, and two symmetrically distributed slide rails 802 are provided on the inner upper surface of the fixed seat 801. The slide rails 802 are slidably connected to the slide seat 803 through a slider in the length direction. A grinding motor 804 is installed on the inner side of the slide seat 803, and a grinding disc 805 is installed at the output end of the grinding motor 804. A screw 806 is threadedly connected to one end of the fixed seat 801, and one end of the screw 806 is rotatably connected to the slide seat 803.

[0033] In this embodiment: the two groups of grinding components 8 have the same structure and are arranged on both sides of the annular cutter 704 in an upper and lower staggered distribution. The grinding discs 805 on the output ends of the two grinding motors 804 are used to grind the side walls on both sides of the annular cutter 704 to maintain the sharpness of the cutting; in addition, the fitting strength between the grinding disc 805 and the annular cutter 704 can be adjusted. By turning the screw 806, the slide 803 can be driven to move along the length direction of the slide rail 802, thereby completing the grinding fitting strength of the grinding disc 805.

[0034] A tensioning assembly 9 for driving the second synchronous wheel 703 to move linearly is also provided in the upper inner chamber of the shell 701, which is used to adjust the distance between the first synchronous wheel 702 and the second synchronous wheel 703. The tensioning assembly 9 includes two guide rods 901, and the two guide rods 901 are symmetrically arranged in the upper inner chamber of the shell 701. A movable seat 902 is slidingly assembled in the length direction of the guide rods 901. The second synchronous wheel 703 is rotatably connected to the movable seat 902. A lifting screw 903 is also provided between the two guide rods 901. The lifting screw 903 is connected to the middle part of the movable seat 902 by a thread, and a second hand wheel 904 is provided at the lower end of the lifting screw 903.

[0035] The tensioning assembly 9 also includes a second locking assembly for limiting the rotation of the lifting screw 903. The second locking assembly includes a second fixed seat 905 fixed at the lower end of the inner chamber at the upper end of the shell 701. The middle part of the second fixed seat 905 is threadedly connected to a second screw rod 906. The second screw rod 906 is rotatably connected to one end of the lifting screw 903 close to the lifting screw 903. One end face of the second extrusion block 907 is adapted to the outer surface contour of the lifting screw 903. One end face of the second extrusion block 907 and the middle outer wall of the lifting screw 903 are both rough surfaces.

[0036] In this embodiment, the tensioning assembly 9 is used to adjust the distance between the first synchronous wheel 702 and the second synchronous wheel 703, thereby straightening the annular cutter 704 to prevent the annular cutter 704 from becoming loose, which affects the cutting accuracy and efficiency of the annular cutter 704. The tensioning assembly 9 is simple, convenient and fast to operate. The specific operation method is to rotate the lifting screw 903 to control the movable seat 902 to slide along the length direction of the guide rod 901. The movable seat 902 will also drive the second synchronous wheel 703 to move synchronously to achieve the purpose of adjusting the distance between the first synchronous wheel 702 and the second synchronous wheel 703. When the second synchronous wheel 703 moves to the specified position, the present scheme also uses the second locking assembly to limit the lifting screw 903, thereby realizing the locking limit of the second synchronous wheel 703 to prevent the lifting screw 903 from accidentally rotating during work.

[0037] It should be noted that the two ends of the lifting screw 903 in this solution are rotatably connected to the upper and lower ends of the inner chamber at the upper end of the shell 701 through bearings.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
