Description

Technical Field

[0001] This utility model relates to the field of pillow filling technology, specifically a pillow filling device. Background Technology

[0002] Pillow filling equipment is a machine that fills pillow shells with fillings such as PP cotton, down, and pearl cotton. It is mainly used in the home textile, furniture, and clothing industries. One automatic quantitative pillow filling machine can complete the workload of ten to fifteen people, greatly reducing labor costs. Moreover, the pillow filling machine produces full and uniform products with a beautiful appearance and a much better feel than those filled by hand.

[0003] Chinese Patent No. CN221971274U discloses a memory foam pillow core filling device, including a fixed support mechanism. Memory foam pillow core clamping mechanisms are rotatably mounted at both ends of the fixed support mechanism, and a pillowcase expansion mechanism is fixedly mounted on one side of the memory foam pillow core clamping mechanism. This invention, through the configuration of the memory foam pillow core clamping mechanism, allows two sets of clamping frames to be arranged opposite each other. Pillow core limiting claws connected to the upper end of the clamping frames can clamp the memory foam pillow core on both sides. Through the configuration of the pillowcase expansion mechanism, two sets of adjusting frames can support the pillowcase on both sides, allowing the pillowcase to present a near-rectangular shape. Furthermore, the support range of the adjusting frames is greater than the clamping range of the pillow core limiting claws, facilitating pillow core filling.

[0004] Although the device can form a support structure inside the pillowcase, it requires manual arrangement of the pillowcase. In addition, the angles of the clamping mechanism and the expansion mechanism cannot be adjusted according to actual use needs during the use of the pillowcase and pillow core, resulting in low flexibility. Therefore, a pillow core filling device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pillow core filling device with advantages such as high flexibility, solving the problem that the angles of the clamping mechanism and the expansion mechanism of the pillow core filling device cannot be adjusted, resulting in low flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pillow core filling device, comprising a base plate, a linear module disposed on the top of the base plate, and a core supply seat fixed on the top of the base plate. Two symmetrically distributed support frames are fixed on the top of the base plate. Adjustment components are provided on the sides of the support frames, and unfolding components are provided on the opposite sides of the two support frames.

[0007] The adjustment assembly includes a fixed plate fixed to one side of two support frames, a connecting frame slidably connected to the left side of the fixed plate, an electric push rod fixed to the connecting frame near the inner left side of the fixed plate, and a movable spring slidably connected inside the fixed plate.

[0008] The unfolding assembly includes four limiting slide rods slidably connected to opposite sides of two fixed plates. A rotating seat is fixed to the side of the limiting slide rod away from the fixed plate. An electric telescopic rod is provided on the front of the rotating seat. An adjusting push rod for adjusting the angle of the electric telescopic rod is provided on the side of the electric telescopic rod near the limiting slide rod. A double-headed push rod for adjusting the unfolding angle of the two electric telescopic rods is provided between the two electric telescopic rods.

[0009] The top surface of the base plate is provided with a sliding groove, the linear module is embedded in the sliding groove and fixedly installed with the base plate, and the linear module is provided with a slidingly connected slider, and the top of the slider is fixed with a clamping claw for fixing the pillow core cover.

[0010] Two slide rails are provided on the opposite side of each of the two fixed plates. The connecting frame is an I-shaped structure, and two connecting slide rods embedded in the slide rails are fixed on the side of each end of the connecting frame closest to the fixed plate.

[0011] The limiting slide rod is located inside the slide rail of the fixed plate. The two ends of the movable spring are fixedly installed with the connecting slide rod and the limiting slide rod, respectively. The electric push rods on both sides of the connecting frame are fixedly installed with the two fixed plates, respectively.

[0012] The electric telescopic rod includes an upper rod and a lower rod, and the two ends of the adjusting push rod are rotatably connected to the limiting slide rod and the upper rod, respectively.

[0013] Both the upper rod and the lower rod are rotatably connected to two limiting slide rods via a rotating seat, and the side of the lower rod near the limiting slide rod is rotatably connected to the rotating seat.

[0014] The upper and lower ends of the double-headed push rod are rotatably connected to the upper rod and the lower rod, respectively.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This pillow filling device uses a linear module to deliver a fixed pillowcase into the device. It controls the double-headed push rod to adjust the angle between the electric telescopic rods, and coordinates with the adjusting push rod to extend and retract the electric telescopic rods on the same side. This allows the pillowcase to smoothly wrap around the electric telescopic rods during movement. The double-headed push rod and the adjusting push rod are then controlled to reset, so that the electric telescopic rods form a rectangular support structure inside the pillowcase, which facilitates the filling of the pillow.

[0017] 2. This pillow filling device uses an electric push rod to extend and retract, which moves the support frame and connecting slide rod, pushing the electric telescopic rod to insert into the pillowcase, thus adapting to pillowcases of different lengths and sizes. After the pillowcase is wrapped by the electric telescopic rod, the electric push rod is controlled to retract, so that the pillowcase can better cover the outlet of the core supply seat, allowing the pillow core to be fully inserted into the pillowcase and avoiding waste of the pillow core.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 The pillow core filling device in this embodiment includes a base plate 1, a linear module 2 disposed on the top of the base plate 1, and a core supply seat 3 fixed on the top of the base plate 1. Two symmetrically distributed support frames 4 are fixed on the top of the base plate 1. Adjustment components 5 are provided on the sides of the support frames 4, and unfolding components 6 are provided on the opposite side of the two support frames 4.

[0024] In this embodiment, the top surface of the base plate 1 is provided with a sliding groove, the linear module 2 is embedded in the sliding groove and fixedly installed with the base plate 1, the linear module 2 is provided with a sliding slider, and the top of the slider is fixed with a clamping claw for fixing the pillow core cover.

[0025] It should be noted that the linear module 2 is a mechanism for realizing linear motion, including but not limited to a linear guide slider mechanism, which consists of a linear guide and a slider. The slider can perform high-precision linear reciprocating motion on the linear guide, which is a conventional technology and will not be elaborated on here. The clamping claw is a unit module that can fix and clamp the pillowcase. It works with the linear module 2 to deliver the pillowcase to the opening position of the core supply seat 3. The core supply seat 3 is connected to an external pillow core supply unit to supply the pillow core filling to the designated position.

[0026] Please see Figure 2 In this embodiment, the adjustment component 5 includes a fixed plate 51 fixed on one side of the two support frames 4. A connecting frame 52 is slidably connected to the left side of the fixed plate 51. An electric push rod 53 is fixed to the connecting frame 52 near the inner left side of the fixed plate 51. A movable spring 54 is slidably connected inside the fixed plate 51.

[0027] In this embodiment, two slide rails are provided on the opposite side of the two fixed plates 51. The connecting frame 52 has an I-shaped structure, and two connecting slide rods 521 embedded in the slide rails are fixed on the side of each end of the connecting frame 52 closest to the fixed plate 51.

[0028] By setting a fixed plate 51 to limit the connection frame 52, the connection frame 52 can move in a specified direction.

[0029] Please see Figure 3 In this embodiment, the unfolding component 6 includes four limiting slide rods 61 that are slidably connected to the opposite side of the two fixed plates 51. A rotating seat 62 is fixed to the side of the limiting slide rod 61 away from the fixed plate 51. An electric telescopic rod 63 is provided on the front of the rotating seat 62. An adjusting push rod 64 for adjusting the angle of the electric telescopic rod 63 is provided on the side of the electric telescopic rod 63 near the limiting slide rod 61. A double-headed push rod 65 for adjusting the unfolding angle of the two electric telescopic rods 63 is provided between the two electric telescopic rods 63.

[0030] In this embodiment, the limiting slide rod 61 is located inside the slide rail of the fixed plate 51. The two ends of the movable spring 54 are fixedly installed with the connecting slide rod 521 and the limiting slide rod 61 respectively. The electric push rods 53 on both sides of the connecting frame 52 are fixedly installed with the two fixed plates 51 respectively.

[0031] By fixing the two ends of the electric push rod 53 to the fixed plate 51 and the connecting frame 52 respectively, the extension and retraction of the electric push rod 53 can drive the connecting frame 52 and the fixed plate 51 to move relative to each other, thereby driving the limit sliding rod 61 to move.

[0032] In this embodiment, the electric telescopic rod 63 includes an upper rod 631 and a lower rod 632. The two ends of the adjusting push rod 64 are rotatably connected to the limiting slide rod 61 and the upper rod 631, respectively. The upper rod 631 and the lower rod 632 are rotatably connected to the two limiting slide rods 61 through the rotating seat 62. The side of the lower rod 632 near the limiting slide rod 61 is rotatably connected to the rotating seat 62. The upper and lower ends of the double-headed push rod 65 are rotatably connected to the upper rod 631 and the lower rod 632, respectively.

[0033] Two electric telescopic rods 63, namely upper rod 631 and lower rod 632, are set on opposite sides of the fixed plate 51. At the same time, an adjusting push rod 64 is provided on the side of the upper rod 631. When the adjusting push rod 64 extends or retracts, it can drive the upper rod 631 to rotate around the rotating seat 62, so that the ends of the upper rods 631 away from the connecting frame 52 rotate towards each other and move closer together, making it easier for the electric telescopic rods 63 to be inserted into the pillowcase. The two ends of the double-headed push rod 65 are connected to the upper rod 631 and the lower rod 632 respectively. Since the side of the upper rod 631 is provided with an adjusting push rod 64 and a limiting slide rod 61 for connection, when the double-headed push rod 65 extends or retracts, it can drive the end of the lower rod 632 away from the connecting frame 52 to move closer to the upper rod 631, making it easier for the pillowcase to wrap the electric telescopic rod 63.

[0034] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) By controlling the extension of the adjusting push rod 64, the electric telescopic rod 63 is pushed to rotate around the rotating seat 62. Since the upper rod 631 and the lower rod 632 are connected by the double-headed push rod 65, the two electric telescopic rods 63 on both sides move towards each other at the ends away from the connecting frame 52. Then, the double-headed push rod 65 is controlled to retract. Since the upper rod 631 is connected to the adjusting push rod 64 and the limiting slide rod 61 on the side, the upper rod 631 cannot rotate in the vertical direction. At this time, the lower rod 632 rotates around the rotating seat 62 under the drive of the double-headed push rod 65. During the rotation, the end of the lower rod 632 away from the connecting frame 52 moves towards the upper rod 631, so that the pillowcase can be nested on the outside of the electric telescopic rod 63 under the drive of the linear module 2.

[0037] (2) By adjusting the angle between the electric telescopic rods 63, the pillowcase is smoothly nested on the outside of the electric telescopic rods 63. The control adjustment push rod 64 and the double-headed push rod 65 are reset, so that the electric telescopic rods 63 form a rectangular support structure inside the pillowcase. Under the push of the linear module 2, the pillowcase moves smoothly to the opening position of the core supply seat 3, which facilitates the filling of the pillow core. This solves the problem that the angle of the clamping mechanism and the expansion mechanism of the pillow core filling equipment cannot be adjusted and the flexibility is not high.
