Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat cover production, in particular to a trimming device for automobile seat cover production. Background Art

[0002] With the rapid development of the automotive industry, demands for personalized and comfortable vehicle interiors are increasing. As an essential component of interior design, car seat covers are also facing increasingly stringent requirements for their design and manufacturing processes. The production process of car seat covers requires cutting of materials such as leather. A Chinese utility model patent (Announcement No.: CN220977497U) discloses a positioning and cutting mechanism for sewing car seat covers. This mechanism applies rotational force to a second threaded rod to squeeze and position the cover material on top of a positioning plate. After positioning, the motor rotates in the opposite direction, adjusting the tension of the cover material via a rubber shaft to prevent it from becoming loose, thereby effectively improving the cutting accuracy of the cover material.

[0003] The above-mentioned device still has some shortcomings when in use: in the prior art, the seat cover is compressed and cut after the extrusion plate is lowered by rotating the bolt. However, since the end of the seat cover is compressed, the seat cover near one end of the extrusion plate cannot be effectively cut when the cutter moves and cuts. The edge of the produced seat cover needs to be separated manually or mechanically, which increases the operation steps in the production process and reduces production efficiency. Therefore, in response to the above situation, a trimming device for automobile seat cover production is proposed. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-5 A trimming device for the production of automobile seat covers includes a cutting table 1, a pair of support frames 2 are provided on the cutting table 1, a first moving mechanism and a second moving mechanism are respectively provided on the pair of support frames 2, a first cylinder 3 is provided on the first moving mechanism, and a moving end of the first cylinder 3 is fixedly connected to a tool holder 4.

[0029] A push plate 5 is fixedly connected to the tool holder 4, and the push plate 5 is in an "L" shape.

[0030] A support block 6 is provided on the second moving mechanism. A pair of upright columns 7 are provided on the top of the support block 6. A fixing plate 8 is provided on the top of the pair of upright columns 7. A pair of second cylinders 801 are provided on the top of the fixing plate 8. The moving ends of the pair of second cylinders 801 pass through the bottom of the fixing plate 8 and are connected to a positioning plate 9. A pair of round holes are formed on the positioning plate 9, and the round holes are in clearance fit with the upright columns 7.

[0031] The support block 6, the fixing plate 8 and the positioning plate 9 are all in the shape of a "ji" character, and the support block 6, the fixing plate 8 and the positioning plate 9 all have channels.

[0032] A pair of first chutes 601 are provided on the inner wall of the channel of the support block 6. A support plate 602 is slidably fitted in the pair of first chutes 601. A first spring 603 is provided in each of the pair of first chutes 601, and the first spring 603 is fixedly connected to one end of the support plate 602.

[0033] A pair of second chutes 901 are provided on the inner wall of the channel of the positioning plate 9. A pressing plate 902 is slidably fitted in the pair of second chutes 901. A second spring 903 is provided in each of the pair of second chutes 901, and the second spring 903 is fixedly connected to one end of the pressing plate 902.

[0034] The bottom of the pressing plate 902 has a groove 9020. An installation frame 9021 is slidably fitted in the groove 9020. A pressing roller 9022 is rotatably fitted on the installation frame 9021. A pressing spring 9023 is provided on the top of the installation frame 9021, and the top of the pressing spring 9023 is fixedly connected to the top surface of the inner wall of the groove 9020.

[0035] In this embodiment, one end of the seat cover is placed on the support block 6. At this time, the support plate 602 also plays a role in lifting the car seat cover. Then, the power supply of the second cylinder 801 is connected, the switch of the second cylinder 801 is turned on, and the two second cylinders 801 work synchronously to push the positioning plate 9 down. The positioning plate 9 descends to press and position the seat cover on the support block 6. At the same time, the pressing roller 9022 performs a limiting treatment on the seat cover on the support plate 602.

[0036] When the first moving mechanism drives the tool rest 4 to move, so that the cutting tool on the tool rest 4 cuts the seat cover, when the cutting tool moves to the support block 6, as the cutting tool further moves, the push plate 5 pushes the support plate 602 and the pressing plate 902 to move in the channel. When the pressing plate 902 moves, the pressing roller 9022 rolls on the seat cover on the surface of the support plate 602. As the support plate 602 and the pressing plate 902 move, the cutting tool can enter the channels of the support block 6, the fixing plate 8 and the positioning plate 9, thereby realizing the cutting treatment of the seat cover positioned on the surface of the support plate 602, making the cutting thorough, reducing the subsequent manual or mechanical separation treatment process, reducing the production cost, and improving the overall efficiency of the production line. <In the above embodiments, the first moving mechanism is used to drive the tool rest to move so that the cutting tool completes the cutting operation, and the second moving mechanism is used to drive the support block 6 to move. The composition structure of the first moving mechanism is the same as the relevant structure for driving the cutting tool to move in the prior art (publication number: CN220977497U), and the composition structure of the second moving mechanism may be the same as the relevant structure for driving the connecting plate to move in the above prior art, which will not be elaborated here too much.

[0039] In this embodiment, as Figure 1 and Figure 3 shown, a cutting tool is provided at the bottom of the tool rest 4, and there is a height difference between the bottom of the cutting tool and the bottom of the push plate 5.

[0040] In this embodiment, there is a height difference between the cutting tool and the push plate 5, so as to ensure that the cutting tool completes the cutting process. At the same time, the push plate 5 contacts the surface of the seat cover, and as the cutting tool moves, the surface of the seat cover can be leveled.

[0042] In this embodiment, as Figure 2 and Figure 4 shown, a pair of through holes are provided at the top of the fixing plate 8, and the through holes are matched with the moving end of the second cylinder 801.

[0043] In this embodiment, by providing the through holes, an activity channel for the moving end of the second cylinder 801 is formed.

[0044] In this embodiment, as Figure 3 shown, the mounting bracket 9021 is in an inverted "U" shape, and assembly holes are provided on both side plates of the mounting bracket 9021, and both ends of the pressure roller 9022 are in clearance fit with the assembly holes.

[0045] In this embodiment, as Figure 3 shown, the pressure roller 9022 is made of rubber material, and the bottom of the pressure roller 9022 penetrates out of the groove 9020.

[0046] In this embodiment, the pressure roller 9022 protrudes out of the groove 9020 and contacts the seat cover on the surface of the support plate 602 to complete the positioning of the seat cover. At the same time, the design of the pressure roller 9022 also facilitates the subsequent movement of the pressing plate 902.
