Description

Technical Field

[0001] This utility model relates to the field of automotive headrest covering technology, specifically an automotive headrest covering machine. Background Technology

[0002] Car seat headrests consist of a headrest frame, headrest foam, and headrest cover. During manufacturing, the headrest foam is solidified onto the headrest frame through a foaming process, and then the headrest cover is wrapped around the headrest foam. The main process of covering the headrest is as follows: first, the headrest rod is inserted into a negative pressure suction tube, then an airtight bag is wrapped around the headrest foam, and the headrest foam comes into contact with the end of the negative pressure suction tube. The volume of the headrest foam is reduced by vacuuming, and then the headrest cover is wrapped around it. Finally, the vacuuming is stopped, and the headrest foam is restored.

[0003] However, after the headrest foam is reduced in volume by vacuuming, the headrest cover is usually wrapped on the headrest foam manually. This can cause the headrest cover to deviate from the headrest foam in position, resulting in poor wrapping consistency and requiring rework, which affects the wrapping efficiency of the headrest. Utility Model Content

[0004] The purpose of this invention is to provide an automotive headrest covering machine to solve the problem mentioned in the background art that the existing clamps directly clamp the steel pipes, which may cause damage if not operated properly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car headrest covering machine, comprising:

[0006] The machine body includes a wrapping machine body, a base plate is fixedly connected to the upper surface of the wrapping machine body, a negative pressure mechanism is provided and connected to the upper surface of the wrapping machine body, and a sealing bag is provided and connected to the outside of the negative pressure mechanism. By inserting the headrest rod into the negative pressure suction pipe on the negative pressure mechanism, and then wrapping the headrest foam with an airtight sealing bag, the headrest foam contacts the end of the negative pressure suction pipe on the negative pressure mechanism. The volume of the headrest foam is reduced by vacuuming, and then a headrest cover is wrapped around it. Finally, the vacuuming is stopped and the headrest foam is restored.

[0007] A coating mechanism includes a support frame, which is fixedly connected to the upper surface of the coating machine body. A cylinder is fixedly connected to the upper surface of the support frame. The output shaft of the cylinder is connected to a connecting plate. A sliding groove is formed on the inner side of the connecting plate. A slider is slidably connected to the inner side of the sliding groove. A connecting rod is fixedly connected to the lower surface of the slider. A placement plate is fixedly connected to the upper surface of the connecting rod. A fixing plate is fixedly connected to the side of the connecting plate. A motor is fixedly connected to the outer surface of the fixing plate. A bidirectional lead screw is connected to the output shaft of the motor.

[0008] Preferably, the bracket is in the shape of an "L" plate, and the cylinder is located directly above the negative pressure mechanism. Its function is to activate the cylinder so that the output shaft of the cylinder can extend or retract, thereby driving the connecting plate to move downward, so that the pillow cover can be put on the headrest foam later.

[0009] Preferably, the slide groove is plate-shaped, the slider is convex block-shaped, and the slider is in two sets slidably connected to the inside of the slide groove. Its function is to start the motor, so that the output shaft of the motor rotates bidirectional lead screw, thereby driving the two sets of sliders to move away from each other, and then, with the start of the motor, the placement plate can be reset.

[0010] Preferably, the connecting rod is rod-shaped, and the placement plate is arc-shaped. Both the connecting rod and the placement plate are in two sets, which facilitates placing both ends of the headrest cover onto the two sets of placement plates before putting it onto the headrest foam to complete the covering.

[0011] Preferably, the bidirectional lead screw is rod-shaped, and its outer surface is connected to two sets of sliders through a screw sleeve. Its function is to start the motor, so that the output shaft of the motor rotates the bidirectional lead screw, thereby driving the two sets of sliders to move away from each other, so that after the covering is completed, the placement plate can be detached and reset.

[0012] Preferably, the upper surface of the base plate is provided with an installation mechanism, including an installation plate, the installation plate being fixedly connected to the upper surface of the base plate, a sealing bag being fixedly connected to the upper surface of the installation plate, a fixing block being fixedly connected to the side of the installation plate, and a bolt being rotatably connected to the upper surface of the fixing block.

[0013] Preferably, the sealing bag is fixedly connected to the upper surface of the mounting plate, and the mounting plate is fixedly connected to the upper surface of the base plate by bolts. Its function is to fix the mounting plate to the upper surface of the base plate by bolts, thereby facilitating the replacement of the sealing bag, preventing the sealing bag from being damaged, causing air leakage, and affecting the extraction of air from the headrest foam.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By placing both ends of the headrest cover on two sets of placement plates, the cylinder is activated, causing its output shaft to extend and retract, thereby moving the connecting plate downwards. This, in turn, moves the headrest cover onto the reduced-volume headrest foam. A negative pressure mechanism then restores the headrest foam to its original shape, completing the headrest coverage. Simultaneously, the placement plates continue to move downwards until they detach from the headrest cover. Activating the motor then causes its output shaft to rotate, moving the two sets of sliders away from each other. The motor's activation then resets the placement plates, eliminating the need for manual headrest coverage and preventing misalignment between the headrest cover and the headrest foam, which would affect the coverage efficiency.

[0016] 2. The mounting plate is fixed to the upper surface of the base plate with bolts, which facilitates the replacement of the sealing bag and prevents the sealing bag from being damaged, causing air leakage and affecting the extraction of air from the headrest foam. Attached Figure Description

A negative pressure mechanism 12 is provided and connected to the upper surface of the wrapping machine body 1. A sealing bag 13 is provided and connected to the outside of the negative pressure mechanism 12. By inserting the headrest rod into the negative pressure suction pipe on the negative pressure mechanism 12, and then wrapping the headrest foam with an airtight sealing bag 13, the headrest foam contacts the end of the negative pressure suction pipe on the negative pressure mechanism 12. The volume of the headrest foam is reduced by vacuuming. Then, a headrest cover is wrapped around it. Finally, the vacuuming is stopped and the headrest foam is restored.

[0027] The coating mechanism includes a support 2, which is fixedly connected to the upper surface of the coating machine body 1. A cylinder 21 is fixedly connected to the upper surface of the support 2. The output shaft of the cylinder 21 is connected to a connecting plate 22. A groove 23 is provided on the inner side of the connecting plate 22. A slider 24 is slidably connected to the inner side of the groove 23. A connecting rod 25 is fixedly connected to the lower surface of the slider 24. A placement plate 26 is fixedly connected to the upper surface of the connecting rod 25. A fixing plate 27 is fixedly connected to the side of the connecting plate 22. A motor 28 is fixedly connected to the outer surface of the fixing plate 27. A bidirectional lead screw 29 is connected to the output shaft of the motor 28.

[0028] Furthermore, the bracket 2 is in the shape of an "L" plate, and the cylinder 21 is located directly above the negative pressure mechanism 12. Its function is to activate the cylinder 21 so that the output shaft of the cylinder 21 can extend and retract, thereby driving the connecting plate 22 to move downward, so that the pillow cover can be put on the headrest foam later.

[0029] Furthermore, the slide groove 23 is plate-shaped, and the slider 24 is a "convex" block. The slider 24 is in two sets of sliding connections inside the slide groove 23. Its function is to start the motor 28, so that the output shaft of the motor 28, the bidirectional lead screw 29, rotates, thereby driving the two sets of sliders 24 to move away from each other. Then, by cooperating with the start of the motor 28, the placement plate 26 can be reset.

[0030] Furthermore, the connecting rod 25 is rod-shaped, and the placement plate 26 is arc-shaped. Both the connecting rod 25 and the placement plate 26 are in two sets. Their function is to facilitate placing both ends of the headrest cover onto the two sets of placement plates 26, and then putting it onto the headrest foam to complete the covering.

[0031] Furthermore, the bidirectional lead screw 29 is rod-shaped, and its outer surface is connected to two sets of sliders 24 through a screw sleeve. Its function is to start the motor 28, so that the output shaft of the motor 28 rotates the bidirectional lead screw 29, thereby driving the two sets of sliders 24 to move away from each other, so that after the covering is completed, the placement plate 26 can be detached and reset.

[0032] Furthermore, an installation mechanism is provided on the upper surface of the base plate 11, including an installation plate 3. The installation plate 3 is fixedly connected to the upper surface of the base plate 11, and a sealing bag 13 is fixedly connected to the upper surface of the installation plate 3. A fixing block 31 is fixedly connected to the side of the installation plate 3, and a bolt 32 is rotatably connected to the upper surface of the fixing block 31.

[0033] Furthermore, the sealing bag 13 is fixedly connected to the upper surface of the mounting plate 3, and the mounting plate 3 is fixedly connected to the upper surface of the base plate 11 by bolts 32. Its function is to fix the mounting plate 3 to the upper surface of the base plate 11 by bolts 32, thereby facilitating the replacement of the sealing bag 13 and preventing the sealing bag 13 from being damaged, leaking air, and affecting the extraction of air from the headrest foam.

[0034] Working principle: A bracket 2 is fixedly connected to the upper surface of the covering machine body 1. A cylinder 21 is fixedly connected to the upper surface of the bracket 2. The output shaft of the cylinder 21 is connected to a connecting plate 22. A groove 23 is opened on the inner side of the connecting plate 22. A slider 24 is slidably connected to the inner side of the groove 23. A connecting rod 25 is fixedly connected to the lower surface of the slider 24. A placement plate 26 is fixedly connected to the upper surface of the connecting rod 25. A fixing plate 27 is fixedly connected to the side of the connecting plate 22. A motor 28 is fixedly connected to the outer surface of the fixing plate 27. A bidirectional lead screw 29 is connected to the output shaft of the motor 28. By placing both ends of the headrest cover on the two sets of placement plates 26, the cylinder 21 is activated, causing the output shaft of the cylinder 21 to extend and retract, thereby driving the connecting plate 26 to extend and retract. Plate 22 moves downward, causing the headrest cover placed on the two sets of placement plates 26 to move downward, so that the headrest cover covers the reduced volume of the headrest foam. Then, through the action of the negative pressure mechanism 12, the headrest foam is restored to its original shape, thus completing the covering of the headrest. At the same time, the placement plate 26 continues to move downward until it is detached from the headrest cover. Then, by starting the motor 28, the output shaft of the motor 28 is rotated by the bidirectional lead screw 29, which drives the two sets of sliders 24 to move in a direction away from each other. Then, with the start of the cooperating motor 28, the placement plate 26 can be reset. Thus, manual covering of the headrest is no longer required, preventing the headrest cover from deviating from the headrest foam and affecting the covering efficiency.

[0035] An mounting plate 3 is movably connected to the upper surface of the base plate 11. A sealing bag 13 is fixedly connected to the upper surface of the mounting plate 3. A fixing block 31 is fixedly connected to the side of the mounting plate 3. A bolt 32 is rotatably connected to the upper surface of the fixing block 31. The mounting plate 3 is fixedly connected to the upper surface of the base plate 11 by the bolt 32, which facilitates the replacement of the sealing bag 13 and prevents the sealing bag 13 from being damaged, causing air leakage, and affecting the extraction of air from the headrest foam.
