Description

Technical Field

[0001] This utility model belongs to the field of automotive carpet forming, specifically an automatic automotive carpet forming and nailing frame transfer trolley. Background Technology

[0002] With the rapid development of the automotive market, the number of automotive interior parts is gradually increasing. As one of the important interior parts of a car, the nail frame is a very important tool in the process of automotive carpet molding. It is mainly used to fix and support the carpet material, ensuring that the material will not move or deform during the pressure molding process.

[0003] When car carpets are pressure-formed, the car carpet is first placed on a nail frame, which is used to limit and fix the carpet. Then, the nail frame with the carpet is moved to the press, and the nail frame with the carpet is placed in the press. The press is used to heat-press the carpet. During the pressing process, the nail frame supports and limits the carpet to prevent it from deforming or moving, thereby improving the quality of the car carpet.

[0004] However, when placing the nail frame with carpet into the press for hot pressing, it is cumbersome to manually move the nail frame to the press and then place it inside the press. In addition, when dealing with multiple nail frames, it is necessary to frequently move and remove the nail frames from the press for replacement, which is time-consuming. This not only increases the labor intensity of the workers, but also reduces the efficiency of automotive carpet forming.

Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0025] Example 1

[0026] like Figure 1-7 As shown, this is the first embodiment of the present invention. This embodiment provides an automatic forming nail frame transfer trolley for automotive carpets, including a press body 1. The front and rear ends of one side of the press body 1 are movably connected to an inlet plate 2. A vehicle body mechanism 3 is provided on one side of the press body 1. A placement mechanism 5 is provided in the inner cavity of the vehicle body mechanism 3, and a lifting mechanism 4 is provided on the surface of the vehicle body mechanism 3. A locking mechanism 6 is provided on both the front and back of the vehicle body mechanism 3. The vehicle body mechanism 3 includes a frame 31, a directional wheel 32, and a universal wheel 33. The lifting mechanism 4 includes a handwheel 41, a shaft 42, a reversing device 43, a driven wheel 44, a driving wheel 45, a transmission rod 46, a worm gear 47, a worm wheel 48, a lead screw 49, and a threaded sleeve 410. The placement mechanism 5 includes a placement frame 51, a guide rail 52, a nail frame body 53, and a connecting sleeve 54. The locking mechanism 6 includes an outer cover 61, a spring 62, a movable plate 63, a connecting plate 64, a clamping plate 65, a clamping rod 66, and a clamping bracket 67.

[0027] like Figure 1-7As shown, the nail frame 53 can be positioned and limited by the placement frame 51 and the guide rail 52. Multiple nail frames 53 can be placed inside the placement frame 51, facilitating simultaneous handling of multiple nail frames 53 and reducing the time spent on frequent handling later. When the placement frame 51 is placed inside the frame 31, pushing the frame 31 transmits thrust to the directional wheels 32 and the omnidirectional wheels 33. The directional wheels 32 and the omnidirectional wheels 33 roll on the ground, reducing resistance and moving the frame 31. The frame 31 then moves the placement frame 53. The frame 51 moves until the frame 31 moves to one side of the press body 1, thereby improving the ease of handling the nail frame 53. By pressing the locking rod 66, one end of the locking rod 66 extends into the inner cavity of the locking frame 67, and the locking frame 67 limits the locking rod 66. The other end of the locking rod 66 drives the movable plate 63 to move. The movable plate 63 drives the spring 62 and the connecting plate 64 to move, causing the spring 62 to deform. One end of the connecting plate 64 drives the locking plate 65 downward into the inner cavity of the guide plate 2, thereby connecting with the guide plate 2, which facilitates the positioning of the frame 31. Then, the guide plate 2 guides the nail frame 31 into the inner cavity of the press body 1. The guide frame 31 moves towards the press body 1 until it contacts the press body 1, facilitating the subsequent placement and removal of the nail frame 53. Then, by turning the handwheel 41, the drive wheel 45 rotates, which in turn drives the driven wheel 44 via a transmission belt. The driven wheel 44, in conjunction with the reversing device 43, drives the shaft 42 and transmission rod 46 to rotate. The transmission rod 46 then drives the worm gear 47 to rotate. Since the worm gear 47 meshes with the worm wheel 48, the worm gear 47 drives the worm wheel 48 to rotate. Because the lead screw 49 is threadedly connected to the threaded sleeve 410, the rotation of the lead screw 49 simultaneously drives the threaded sleeve... The threaded sleeve 410 moves up and down, and through the connecting sleeve 54, it drives the placement frame 51, guide rail 52, and nail frame 53 to adjust the height, so that the nail frame 53 is flush with the inlet and outlet of the press body 1. This improves the accuracy of the nail frame 53 entering or leaving the press body 1. By pushing or pulling the nail frame 53, the nail frame 53 will move to one side through the limit of the guide rail 52, which facilitates the nail frame 53 entering or leaving the interior of the press body 1. This improves the convenience of replacing and transporting the nail frame 53, saving time and effort and increasing processing efficiency.

[0028] Example 2

[0029] Reference Figure 1 , 2 3 and 6 are the second embodiment of this utility model, which is based on the previous embodiment.

[0030] In this embodiment, the directional wheel 32 is disposed at the front and rear ends of the bottom right side of the frame 31, the universal wheel 33 is disposed at the front and rear ends of the bottom left side of the frame 31, and the surface of the universal wheel 33 is provided with brake pads. The front and rear ends of the inner cavity of the frame 31 are fixedly connected with guide rods 311, and the front and back sides of the frame 31 are fixedly connected with push frames 312. The surface of the guide rods 311 is covered with guide sleeves 511.

[0031] Handwheel 41 is located on the front and back of frame 31. Commutator 43 is located at the front and rear ends of the bottom of frame 31. Axle 42 is located on the left side of the bottom of frame 31. Both ends of axle 42 are connected to commutator 43. Driven wheel 44 is connected to commutator 43. Drive rod 46 is located on the right side of commutator 43 and is connected to commutator 43. Worm 47 is fixed on both sides of the surface of drive rod 46. Worm 47 meshes with worm wheel 48. The bottom of worm wheel 48 is connected to frame 31. Lead screw 49 is connected to worm wheel 48. Threaded sleeve 410 is sleeved on the surface of lead screw 49 and threadedly connected to lead screw 49. Connecting sleeve 54 is fixedly connected to threaded sleeve 410.

[0032] The surface of the axle 42 is movably connected to the axle seat 421 via a bearing, and the bottom of the axle seat 421 is fixedly connected to the frame 31. The front and back of the frame 31 are fixedly connected to the support plate 451, and the other side of the support plate 451 is movably connected to the drive wheel 45.

[0033] like Figure 1 , 2As shown in Figures 3 and 6, by pushing the pusher 312, the pusher 312 can transmit force to the frame 31. The frame 31 will then transmit the thrust to the directional wheel 32 and the swivel wheel 33. The directional wheel 32 and the swivel wheel 33 roll on the ground, which can reduce the resistance to movement. The directional wheel 32 and the swivel wheel 33 will drive the frame 31 to move. The frame 31 will drive the placement rack 51 to move to one side of the press body 1. The brake pads on the surface of the swivel wheel 33 can stop the swivel wheel 33 from rotating, ensuring stability when stopped, thereby improving the convenience of handling the nail frame 53. By turning the handwheel 41, the handwheel 41 drives the drive wheel 45 to rotate. The drive wheel 45 drives the driven wheel 44 to rotate through the transmission belt. The driven wheel 44, in conjunction with the reversing device 43, will drive the shaft 42 and the transmission rod 46 to rotate through the transmission rod. 46 drives the worm gear 47 to rotate. Since the worm gear 47 and the worm wheel 48 are meshed, the worm gear 47 will drive the worm wheel 48 to rotate. Since the lead screw 49 and the threaded sleeve 410 are threadedly connected, the lead screw 49 will drive the threaded sleeve 410 to move up and down while rotating. The threaded sleeve 410 will drive the connecting sleeve 54 to move up and down. The connecting sleeve 54 will drive the placement frame 51, the guide rail 52 and the nail frame 53 to adjust the height. When the placement frame 51 is moving, the placement frame 51 drives the guide sleeve 511 and the guide rod 311 to slide, thereby ensuring the stability of the placement frame 51 during movement and preventing the placement frame 51 from being misaligned during movement, until the placement frame 51 drives the nail frame 53 to be flush with the inlet and outlet of the press body 1, thereby improving the accuracy of the nail frame 53 entering or being taken out of the press body 1.

[0034] Example 3

[0035] Reference Figure 1 , 2 4 and 7 are the third embodiment of this utility model, which is based on the first two embodiments.

[0036] In this embodiment, the placement rack 51 is located in the inner cavity of the frame 31, the guide rail 52 is located on both sides of the inner cavity of the placement rack 51, the inner cavity of the guide rail 52 is movably connected to the limiting wheel 521, the nail frame 53 is located on the top of the guide rail 52 and is slidably connected to the top of the guide rail 52, and the limiting wheel 521 is in contact with the bottom of the nail frame 53, the connecting sleeve 54 is located at the front end and rear end of both sides of the placement rack 51 and is fixedly connected to the placement rack 51, and the guide sleeve 511 is located around both sides of the placement rack 51 and is fixedly connected to the placement rack 51.

[0037] The outer cover 61 and the bracket 67 are located on both sides of the frame 31 and are fixedly connected to the frame 31. The first support plate 631 and the second support plate 641 are fixedly connected to the top of the inner cavity of the outer cover 61, respectively. The movable plate 63 is movably connected to one side of the first support plate 631 through a pin, and the connecting plate 64 is movably connected to the inner cavity of the second support plate 641 through a pin. The movable plate 63 and the connecting plate 64 are movably connected through a pin. The spring 62 is located at the bottom of the movable plate 63 and is fixedly connected to the movable plate 63. The bottom of the spring 62 is fixedly connected to the bottom of the inner cavity of the outer cover 61. One end of the movable plate 63 is movably connected to the locking rod 66 through a pin. The locking rod 66 extends to the inner cavity of the bracket 67 and is movably connected to the inner cavity of the bracket 67. The locking plate 65 is fixedly connected to one end of the connecting plate 64. The other end of the locking plate 65 extends to the inner cavity of the guide plate 2 and is movably connected to the inner cavity of the guide plate 2.

[0038] like Figure 1 , 2 As shown in Figures 4 and 7, the nail frame 53 can be positioned and limited by the placement frame 51 and the guide rail 52. Multiple nail frames 53 can be placed inside the placement frame 51, facilitating simultaneous handling of multiple nail frames 53 and reducing the time spent on frequent handling of the nail frames 53. By pushing or pulling the nail frame 53, it will move to one side by the limiting position of the guide rail 52, and the limiting wheel 521 will contact the nail frame 53, reducing the resistance during movement. This facilitates the entry and exit of the nail frame 53 into or out of the press body 1, improving the convenience of nail frame 53 replacement. After the frame 31 moves to one side of the press body 1, the clamping rod 66 is pressed. One end of the clamping rod 66 extends into the inner cavity of the clamping bracket 67, which limits the clamping rod 66. At the same time, the other end of the clamping rod 66 drives the movable plate 63 to move around the first support plate 631 as the axis. Then, one end of the movable plate 63 drives the spring 62 and one end of the connecting plate 64 to move upward, causing the spring 62 to deform. The other end of the connecting plate 64 drives one end of the clamping plate 65 to move downward until one end of the clamping plate 65 enters the inner cavity of the guide plate 2, completing the connection with the guide plate 2, which facilitates the positioning of the frame 31.

[0039] In use, multiple nail frames 53 are first placed on the guide rails 52 inside the placement rack 51. Because multiple guide rails 52 are provided, multiple nail frames 53 can be positioned and limited, facilitating simultaneous handling of multiple nail frames 53 and reducing the time spent on frequent handling later. The placement rack 51 is placed inside the frame 31. When the frame 31 is pushed, it transmits thrust to the directional wheels 32 and the swivel wheels 33. The directional wheels 32 and swivel wheels 33 roll on the ground, reducing resistance. The directional wheels 32 and swivel wheels 33 also drive the frame 31 to move. The placement rack 51 moves until the frame 31 moves to one side of the press body 1, thereby improving the ease of handling the nail frame 53. Then, by pressing the locking rod 66, one end of the locking rod 66 extends into the inner cavity of the locking frame 67, and the locking frame 67 limits the locking rod 66. At the same time, the other end of the locking rod 66 drives the movable plate 63 to move around the first support plate 631 as the axis. Then, one end of the movable plate 63 drives one end of the spring 62 and the connecting plate 64 to move upward, causing the spring 62 to deform. The other end of the connecting plate 64 drives one end of the locking plate 65 to move downward until one end of the locking plate 65 enters the inner cavity of the guide plate 2, completing the connection with the guide plate 2. This facilitates the positioning of the frame 31. The guide plate 2 then guides the frame 31 towards the press body 1 until it contacts it, facilitating the later removal and replacement of the nail frame 53. Next, rotating the handwheel 41 drives the drive wheel 45, which in turn drives the driven wheel 44 via a transmission belt. The driven wheel 44, in conjunction with the commutator 43, drives the shaft 42 and transmission rod 46 to rotate. The transmission rod 46 then drives the worm gear 47 to rotate. Since the worm gear 47 meshes with the worm wheel 48, it drives the worm wheel 48 to rotate. Because the lead screw 49 and the threaded sleeve 410 are threaded together, the lead screw... As rod 49 rotates, it drives threaded sleeve 410 to move up and down. Threaded sleeve 410 drives connecting sleeve 54 to move up and down. The connecting sleeve 54 drives placement frame 51, guide rail 52, and nail frame 53 to adjust their height, making nail frame 53 flush with the inlet and outlet of press body 1. This improves the accuracy of nail frame 53 entering or leaving the press body 1. By pushing or pulling nail frame 53, nail frame 53 will move to one side through the limit of guide rail 52, facilitating nail frame 53 entering or leaving the interior of press body 1. This improves the convenience of nail frame 53 replacement and handling, saving time and effort and increasing processing efficiency.
