Description

Technical Field

[0001] The utility model relates to the field of automobile roof manufacturing, in particular to an automobile roof fabric clamping device, which is used for taking out a single fabric from a plurality of stacked fabrics. Background Art

[0002] The automotive headliner manufacturing plant features a raw material storage base, on which multiple layers of fabric are stacked to form a raw material pile. Above the base is a headliner fabric removal device. This device comprises front and rear transverse rails, mounted with a slider and a first drive mechanism. The slider is mounted with a vertical cylinder, whose drive rod extends downward. A needling mechanism is located at the base of the drive rod, housing needles and a second drive mechanism. The needles are driven downward by the second drive mechanism to extend beyond the bottom wall of the needling mechanism. A conveyor belt is located in front of the raw material storage base. The working process is as follows: The needling mechanism is driven downward by a vertical cylinder to the top surface of the car roof material pile, driving the needles to extend downward and penetrate the topmost individual fabric. The vertical cylinder then moves upward and resets, driving the needles and the individual fabric upward and away from the material pile. The slider is driven forward by a first drive device, driving the needling mechanism, its needles, and the individual fabric forward to above the conveyor belt. The needles retract and reset, allowing the individual fabric to break away from the needles and fall onto the conveyor belt, where they are transported forward to the next station for pressing. A drawback of the existing technology is that when the individual fabric falls onto the conveyor belt, it may be partially wrinkled due to collision. In this state, it is conveyed to the next station for pressing, resulting in a shape that does not meet the requirements after pressing. Utility Model Content

[0005] Further, the needle of the right needle punching mechanism specifically extends obliquely downward and leftward, and the needle of the right needle punching mechanism specifically extends obliquely downward and rightward.

[0006] Further, the compression roller includes two roller bodies arranged side by side in an upper and lower relationship, and a gap is left between the two roller bodies to receive the single fabric and press it to flat.

[0014] The present invention will be further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1As shown, a clamping device for automobile roof fabric includes a raw material base 1, on which multiple layers of fabric are stacked, forming a raw material pile 2. Two horizontal slide rails 3 are provided above the left and right side walls of the raw material pile 2. The bottom walls of the slide rails 3 are equipped with a first drive device (a horizontal cylinder, not shown) and a slider 4 driven thereby to move along the slide rails 3. A vertical cylinder 5 is mounted on the bottom wall of the slider 4. The drive rod of the vertical cylinder 5 can extend downward. A needling mechanism 6 is mounted at the bottom of the drive rod. The needling mechanism 6 contains needles 13 and a micro-cylinder (not shown). The needles 13 on the right needling mechanism 6 are driven by the corresponding micro-cylinder, which serves as a second drive device, to extend obliquely downward and slightly to the left, out of the bottom wall of the needling mechanism 6. The needles 13 on the left needling mechanism 6 are driven by the corresponding second drive device to extend obliquely downward and slightly to the right, out of the bottom wall of the needling mechanism 6. Two clamping jaws are respectively installed on the rear side walls of the two needling mechanisms 6. Each of the two clamping jaws is provided with a pair of horizontal clamping fingers. The two pairs of clamping fingers face each other, and the upper clamping fingers 8 of each pair of clamping fingers are flush with the bottom wall of the corresponding needling mechanism 6. Two mounting posts 10 are respectively provided on the left and right sides in front of the raw material base 1. Between the two mounting posts 10, there are left and right horizontal pressure rollers 9. The pressure rollers 9 include two roller bodies. The upper and lower rollers are arranged side by side with a gap, and the top of the gap is aligned. Figure 1 The bottom wall of the acupuncture mechanism 6 is aligned with the bottom of the gap Figure 1 The top wall of the lower clamping finger 7 in the middle. A conveyor belt 11 is provided in front of the pressure roller 9, and the top wall of the conveyor belt 11 is aligned with the gap between the two roller bodies.

[0016] The working process is as follows: Figure 2 As shown, the two lower clamping fingers 7 are Figure 1 The two needle-punching mechanisms 6 are driven by the vertical cylinder 5 to move from the horizontal state to the vertical state, thereby respectively passing over the left and right side walls of the raw material pile 2. Figure 1 Move to Figure 2 The state contacts the single fabric 12 on the top layer of the raw material pile 2, and the two needles 13 are driven by the second driving device to extend downward to pierce the single fabric 12 to catch it. Figure 3 As shown, the needling mechanism 6 is driven upward by the vertical cylinder 5 to move the needle 13 and the single fabric 12 upward away from the raw material pile 2. Figure 3 The two lower clamping fingers 7 in the vertical state are rotated upward to the horizontal state, so that Figure 4 As shown, the two upper clamping fingers 8 respectively clamp the left and right edges of the single fabric 12, and the needle 13 retracts. Next, the slider 4 is driven forward by the first driving device to drive the needling mechanism 6, the clamping claws, the needle 13 and the single fabric 12 to move forward to the pressure roller 9. The front end of the single fabric 12 has entered the gap between the two rollers, as shown in FIG. Figure 5As shown, the upper clamping fingers 8 open upward to release the single fabric 12, which is then drawn into the pressing roller 9 and received. During this receiving process, the bottom wall of the single fabric 12 is supported by the two lower clamping fingers 7, and the top wall is blocked by the bottom walls of the two needling mechanisms 6. This limits the vertical space and prevents local protrusions from overlapping and wrinkling. The single fabric 12 is then pressed by the pressing roller 9 until it is flat and smooth, and then sent to the conveyor belt 11.

[0017] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
