Description

Technical Field

[0001] This invention relates to the field of cotton stuffing machine technology, specifically to an automatic cotton stuffing machine for the production of sponge cushions. Background Technology

[0002] In the traditional cotton stuffing machine operation process, workers usually pre-load the sponge pad, then put the cloth cover on the outside of the machine that guides the movement of the sponge pad. After the machine pushes the sponge pad completely into the cloth cover, the finished product is then manually removed from the work station.

[0003] The above process involves multiple steps such as feeding, covering with fabric, and taking out finished products, all of which rely on manual operation. Throughout the production process, manual work occupies a large amount of auxiliary time, and the overall machine operation speed is limited by the speed of manual operation, making it difficult to achieve continuous production and restricting the improvement of overall production efficiency. Moreover, the repetitive and heavy operation also exacerbates the fatigue of operators. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows: An automatic stuffing machine for producing sponge seat cushions includes a feeding mechanism, a stuffing mechanism, and a bag-supporting mechanism. The feeding mechanism includes a first support frame, a stuffing channel fixed to the top of the first support frame, two metal plates located behind the stuffing channel and fixed to the top of the first support frame, a receiving plate fixed between the two metal plates, a belt conveyor, and a pressure plate passing through the belt conveyor and fixed between the two metal plates. The belt conveyor is suspended above the receiving plate. The stuffing mechanism includes a second support frame inserted into the first support frame, two electric push rods fixed to the second support frame, and a U-shaped connector fixed to the movable end of each electric push rod. The system includes a U-shaped head, a push rod rotatably connected to the U-shaped head, two torsion springs fixed between the U-shaped head and the push rod, a stop block attached to the rear side of the push rod and fixed to the U-shaped head, and a bag-supporting mechanism. The bag-supporting mechanism includes a rotating column located on one side of the stuffing channel and rotatably connected to the second support frame, a motor fixed between the second support frame and the rotating column, three booms ring-fixed to the front end of the motor, a rod movably passing through the outer end of the booms, a rubber plug filling the space between the booms and the rods, a bag-supporting sleeve fixed to the rods, a plastic sheet fixed to one end of the bag-supporting sleeve, and a trapezoidal plate located on the other side of the stuffing channel and fixed to the second support frame.

[0006] By adopting the above technical solution, the belt conveyor continuously presses the sponge pad on the receiving plate into the stuffing channel. At the same time, the worker stands in front of the rotating column and continuously puts cloth covers on multiple support bags. When the plastic sheet on the support bag is horizontally attached to the trapezoidal plate, the support bag is just placed in front of the stuffing channel. Then, the moving end of the electric push rod pulls the push rod forward, and the push rod presses the sponge pad into the cloth cover until the cushion is fully formed. Then the support bag is pushed off by the push rod. The entire production process only requires the worker to put on the cloth bag, which greatly reduces the number of manual interventions, improves production efficiency, and reduces labor intensity.

[0007] In a preferred embodiment, the present invention can be further configured such that two electric push rods are located on both sides of the cotton stuffing channel, and the two electric push rods are connected in series.

[0008] In a preferred embodiment, the present invention can be further configured such that: the push rod is composed of a positioning rod, a sleeve and a rod body; the positioning rod is rotatably embedded inside the U-shaped head; the sleeve is fixedly sleeved on the outside of the positioning rod; the rod body is fixedly connected to the inside of the sleeve; and slides suitable for the push rod to slide are provided on both sides of the cotton stuffing channel.

[0009] In a preferred embodiment, the present invention can be further configured such that two torsion springs located inside the U-shaped head are respectively embedded in the top and bottom of the sleeve, and the torsion springs are sleeved on the outside of the positioning rod.

[0010] In a preferred embodiment, the present invention can be further configured such that: the boom consists of a long arm and a ring sleeve, the ring sleeve is located outside the rotating column, and the long arm is fixed between the rotating column and the ring sleeve.

[0011] In a preferred embodiment, the present invention can be further configured such that the boom is composed of a U-shaped rod and a cylindrical body, the cylindrical body being disposed inside the ring and fixedly sleeved on the outside of the U-shaped rod.

[0012] In a preferred embodiment, the present invention can be further configured such that the support bag is composed of a frame, four clamping plates and two extension plates, the four clamping plates are integrally formed on the four side walls of the frame, and the two extension plates are located at both ends of the frame and are integrally formed with the frame.

[0013] In a preferred embodiment, the present invention may be further configured such that: a feeding assembly is provided on the front side of the second support frame, the feeding assembly includes a base located on the front side of the second support frame, a sliding plate rotatably mounted on the top of the base, an arc plate fixed between the base and the sliding plate, and a baffle frame fixed to one end of the base, wherein the sliding plate is inclined.

[0014] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. In this invention, the belt conveyor continuously presses the sponge pad on the receiving plate into the stuffing channel. At the same time, the worker stands in front of the rotating column and continuously puts cloth covers on multiple support bags. When the plastic sheet on the support bag is horizontally attached to the trapezoidal plate, the support bag is just placed in front of the stuffing channel. Then, the moving end of the electric push rod pulls the push rod forward, and the push rod presses the sponge pad into the cloth cover until the cushion is fully formed. Then the support bag is pushed off by the push rod. The entire production process only requires the worker to put on the cloth bag, which greatly reduces the number of manual interventions, improves production efficiency, and reduces labor intensity.

[0015] 2. In this invention, when the worker puts the cloth cover on the support bag cover, the extension plate guides the cloth cover to avoid the cloth cover getting stuck during the cloth cover putting process. Then, the clamping plate clamps the cloth cover bag opening, which allows the sponge pad to be smoothly and completely stuffed into the cloth cover. The structural design of the support bag cover makes the sponge filling operation smoother and more continuous, ensuring the production efficiency of sponge cushions.

[0016] 3. In this invention, when the formed cushion falls from a height onto the slide plate, the impact force of the fall causes the arc plate to vibrate, and then the slide plate shakes the cushion off quickly. The cushion is then collected by the baffle frame, and the material collection method can be completed automatically, which greatly improves the ease of material collection.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0021] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic cotton stuffing machine for the production of sponge cushions. Example

[0022] Combination Figures 1-8 As shown, the present invention provides an automatic stuffing machine for producing sponge cushions, including a feeding mechanism 100, a stuffing mechanism 200, and a bag-supporting mechanism 300. The feeding mechanism 100 includes a support frame 110, a stuffing channel 120 fixedly connected to the top of the support frame 110, two metal plates 130 located on the rear side of the stuffing channel 120 and fixedly connected to the top of the support frame 110, a receiving plate 140 fixedly connected between the two metal plates 130, a belt conveyor 150, and a pressure plate 160 passing through the belt conveyor 150 and fixedly connected between the two metal plates 130. The belt conveyor 150 is suspended above the receiving plate 140. The feeding mechanism 200 includes a second support 210 inserted into the first support 110, two electric push rods 220 fixedly connected to the second support 210, a U-shaped head 230 fixedly connected to the movable end of the electric push rod 220, a push rod 240 rotatably connected to the U-shaped head 230, two torsion springs 250 fixedly connected between the U-shaped head 230 and the push rod 240, and a stop block 260 attached to the rear side of the push rod 240 and fixedly connected to the U-shaped head 230. The bag-supporting mechanism 300 includes a rotating column 310 located on one side of the stuffing channel 120 and rotatably connected to the second support frame 210, a motor 320 fixed between the second support frame 210 and the rotating column 310, three lifting arms 330 ring-fixed to the front end of the motor 320, a lifting rod 340 movably passing through the outer end of the lifting arm 330, a rubber plug 350 filling the space between the lifting arm 330 and the lifting rod 340, a bag-supporting sleeve 360 ​​fixedly connected to the lifting rod 340, a plastic sheet 370 fixedly connected to one end of the bag-supporting sleeve 360, and a trapezoidal plate 380 located on the other side of the stuffing channel 120 and fixedly connected to the second support frame 210.

[0023] Furthermore, the push rod 240 is composed of a positioning rod 241, a sleeve 242, and a rod body 243. The positioning rod 241 is rotatably embedded inside the U-shaped head 230, the sleeve 242 is fixedly sleeved on the outside of the positioning rod 241, and the rod body 243 is fixedly connected to the inside of the sleeve 242. Slides suitable for the sliding of the push rod 240 are provided on both sides of the cotton stuffing channel 120. The structural design of the push rod 240 enables it to complete the cotton stuffing operation, and when resetting, even if it is blocked by the subsequent sponge pad, the push rod 240, which can rotate in the direction of the electric push rod 220, can be smoothly reset, providing conditions for continuous cotton stuffing.

[0024] Furthermore, two torsion springs 250 located inside the U-shaped head 230 are respectively embedded in the top and bottom of the sleeve 242. The torsion springs 250 are sleeved on the outside of the positioning rod 241. The layout design of the torsion springs 250 can ensure that the push rod 240 can be smoothly reset after rotation.

[0025] Furthermore, the boom 330 is composed of a long arm 331 and a ring 332. The ring 332 is located outside the rotating column 310, and the long arm 331 is fixed between the rotating column 310 and the ring 332. The structural design of the boom 330 can stably support the support bag 360.

[0026] Furthermore, the lifting rod 340 is composed of a U-shaped rod 341 and a cylindrical body 342. The cylindrical body 342 is located inside the ring 332 and is fixedly sleeved on the outside of the U-shaped rod 341. The lifting rod 340 is provided so that its angle can be flexibly adjusted within the ring 332 to ensure that the bag support 360 can be placed correctly in front of the cotton stuffing channel 120, so that the cotton stuffing operation can be carried out stably.

[0027] Furthermore, the support bag cover 360 is composed of a frame 361, four clamping plates 362 and two extension plates 363. The four clamping plates 362 are integrally formed on the four side walls of the frame 361, and the two extension plates 363 are located at both ends of the frame 361 and are integrally formed with the frame 361. The structural design of the support bag cover 360 makes it easy for workers to put the cloth cover on the outside of the support bag cover 360, and then the clamping plates 362 can fix the opening of the cloth cover, so that the sponge pad can be completely inserted into the inside of the cloth cover. Example

[0028] Combination Figure 1 , 4 and Figure 5 As shown, based on Embodiment 1, two electric push rods 220 are located on both sides of the cotton stuffing channel 120, and the two electric push rods 220 are connected in series. The connection method of the electric push rods 220 allows the sponge pad to be stably stuffed into the cloth cover. Example

[0029] Combination Figure 1 and Figure 7 As shown in the above embodiment, a feeding assembly 400 is provided on the front side of the second support frame 210. The feeding assembly 400 includes a base 410 located on the front side of the second support frame 210, a slide plate 420 rotatably mounted on the top of the base 410, an arc plate 430 fixed between the base 410 and the slide plate 420, and a baffle frame 440 fixed to one end of the base 410. The slide plate 420 is inclined. When the formed cushion falls from a height onto the slide plate 420, the impact force of the fall causes the arc plate 430 to vibrate. Then the slide plate 420 shakes the cushion off quickly. The cushion is collected uniformly by the baffle frame 440. The material collection method can be completed automatically, which greatly improves the ease of material collection.

[0030] The working principle and usage process of this invention are as follows:

[0031] When this device is put into actual use, the sponge pad to be filled is laid flat on the top of the receiving plate 140. Then the belt conveyor 150 flattens the sponge pad and presses it into the cotton stuffing channel 120. When a sponge pad is completely inserted into the cotton stuffing channel 120, it falls to the front of the two push rods 240, ready to be filled into the cloth cover. At the same time, the motor 320 drives the rotating column 310 to rotate continuously, which in turn drives multiple booms 330 to rotate slowly. Then, the support bag cover 360 connected to the boom 340 rotates together. The staff stands in front of the rotating column 310 and puts the seat cushion cover on the outside of the empty support bag cover 360 one after another. The cover is clamped by the clamp plate 362 to ensure that the cover does not shift when the sponge pad is inserted into the cover, thereby ensuring the filling effect. During the rotation of the support bag cover 360, when the plastic sheet 370 at one end contacts the trapezoidal plate 380, the trapezoidal plate 380 creates resistance to the plastic sheet 370, causing the support bag cover 360 to adjust its own posture. The hanging rod 340 provides conditions for the posture adjustment of the support bag cover 360 by squeezing the rubber plug 350. Then, it controls the movable ends of the two electric push rods 220 to retract. The movable ends of the electric push rods 220 drive the push rod 240 through the U-shaped head 230. The push rod 240 smoothly presses the sponge pad in the cotton stuffing channel 120 into the cloth cover on the support bag cover 360. When the movable end of the electric push rod 220 retracts to the limit position, the sponge cushion is formed and pushed away from the support bag cover 360 by the push rod 240.

[0032] Throughout the process, staff only need to continuously bag the bags, which greatly reduces the number of manual interventions, thus improving production efficiency and reducing labor intensity.

[0033] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
