Description

Technical Field

[0001] This invention relates to the field of pillowcases, and more specifically to a pillowcase heat-pressing device. Background Technology

[0002] As people's living standards continue to improve, their requirements for quality of life are also increasing, especially for sleep. Traditional pillowcases do not have health-preserving and antibacterial functions, so a pillowcase heat-pressing device is needed to give the finished pillowcases health-preserving and antibacterial effects. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the background art and provide a pillowcase heat pressing device.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A pillowcase hot pressing device includes a frame with a conveyor belt on it. Several pillowcase placement plates are arranged along the conveyor belt in the conveying direction. The conveyor belt is provided with a primary automatic powder feeding mechanism, a secondary automatic powder feeding mechanism, a glue spraying mechanism, a fabric layer picking mechanism, a hot pressing mechanism, and a drying mechanism in sequence along the conveying direction. The secondary automatic powder feeding mechanism is also provided with a residual powder collection mechanism on its side.

[0006] This invention involves placing the pillowcase bottom-up on a pillowcase placement board, then conveying it to various workstations via a conveyor belt to fill it with lavender powder. This ensures that each groove is fully filled with lavender powder, preventing omissions caused by manual installation, thus improving work efficiency. The finished pillowcases promote sleep through the lavender powder and also have antibacterial properties.

[0007] The residual powder collection mechanism includes a collection hood with its opening facing the pillowcase placement board. A powder collection tank is connected to the back of the collection hood via a pipe. An air inlet is provided at the top of the powder collection tank, and an air outlet is provided at the lower part of the side wall of the powder collection tank. A fan is connected to the air outlet, and a filter screen is provided inside the powder collection tank, located above the air outlet.

[0008] Excess lavender powder is collected in a powder collection tank through a fan hood to prevent excess lavender particles from remaining on the pillowcase, which could result in a grainy texture after subsequent painting and hot pressing.

[0009] Preferably, the pillowcase placement board includes a base plate, and the top of the base plate has a groove that cooperates with the filling groove, so that the filling groove can be placed in the groove.

[0010] Preferably, the automatic powder feeding mechanism includes a uniform discharge box, a discharge pipe, a feeding pipe, a receiving pipe, a shaped annular belt, a pulley, a fixed plate, a pressing electric push rod, and a material box bracket. The fixed plate is located above the conveyor belt, and the pressing electric push rod is located above the fixed plate. The motor end of the pressing electric push rod is fixed to the frame, and the push rod end of the pressing electric push rod is fixedly connected to the fixed plate. The shaped annular belt is located at the inner top of the frame, and the pulley is rotatably located at the inner top of the frame. The pulley and the shaped annular belt cooperate with each other. The material box bracket is fixed on the shaped annular belt. The uniform discharge box is fixed on the material box support. The discharge pipe is located at the lower part of the side wall of the uniform discharge box. The feed pipe is located at the end of the discharge pipe and is perpendicular to the discharge pipe. Several receiving pipes are located on the fixed plate. The top surface of the receiving pipe is flush with the upper surface of the fixed plate. The bottom of the receiving pipe extends outside the fixed plate. Each receiving pipe corresponds to a groove. The bottom of the receiving pipe is provided with an automatic opening and closing sealing plate. The route of the irregular ring belt allows the uniform discharge box to pass through each receiving pipe in sequence. The belt pulley is driven by a motor, which is existing technology and will not be described in detail in this case.

[0011] This invention utilizes the rotation of a pulley to drive a shaped annular belt, which in turn moves the uniform discharge box. When the lower feed tube moves above the first receiving tube, the uniform discharge box discharges material into the receiving tube, then stops discharging. This process continues until the uniform discharge box moves to the next receiving tube, at which point it discharges again. The uniform discharge box follows the shaped annular belt, moving sequentially above each receiving tube until material is deposited into each tube. After this, discharging stops, the uniform discharge box returns to its original position, and each automatic opening and closing sealing plate automatically opens, allowing material to fall into the filling groove. The sealing plate then closes, turning the receiving tube into a pressing column. The fixing plate moves down via a pressing electric push rod, pressing and compacting the filling groove filled with material. This completes the automatic filling and pressing process, eliminating the need for manual labor and increasing precision. Furthermore, the material dropping and pressing are completed in one area, ensuring sufficient space for compaction and guaranteeing the finished product has sufficient hardness to form the massage protrusion.

[0012] The arrival time of the feed pipe above the receiving pipe can be detected by installing inductive sensors, such as infrared sensors or limit switches. Alternatively, the arrival time can be calculated by the system to determine the time when the feed pipe reaches the receiving pipe. These are all mature technologies, so they will not be elaborated on in this case.

[0013] Preferably, the uniform discharge box includes a storage box, a stirring wheel, and a spiral conveying rod. The storage box is fixed on a material box support. The spiral conveying rod is located at the inner bottom of the storage box and is rotatably connected to the storage box via a bearing. One end of the spiral conveying rod extends outside the storage box, and the other end extends into the discharge pipe. The stirring wheel meshes with the spiral conveying rod. The stirring wheel is rotatably mounted on the side wall of the storage box, and a stirring rod is fixedly connected to the side wall of the stirring wheel. The rotation of the spiral conveying rod is driven by a motor, which is existing technology and will not be described in detail here.

[0014] This invention uses the rotation of a spiral conveyor rod to push the powder in the storage box out evenly, while simultaneously driving the stirring wheel and stirring rod to continuously stir the powder in the container, preventing the powder from clumping. By driving the spiral conveyor rod, both the spiral conveyor rod and the stirring wheel can be rotated, saving energy.

[0015] Preferably, the automatic opening and closing sealing plate includes a rotary motor, a sealing plate body, fixed ears, a rotating shaft, and a connecting plate. The fixed ears are located below the side wall of the receiving tube. The rotating shaft passes through the two fixed ears and is rotatably connected to the fixed ears via bearings. One end of the rotating shaft is fixedly connected to the rotary motor. The top of the connecting plate is sleeved and fixed on the rotating shaft, and the bottom of the connecting plate is fixedly connected to the sealing plate body.

[0016] This invention controls the motor to adjust the rotation of the rotating shaft, thereby driving the connecting plate to rotate, which in turn causes the sealing plate body to close and open.

[0017] Preferably, the fabric layer taking mechanism includes a slide rail, a material taking electric telescopic rod, a material taking fixing plate, and a vacuum suction cup. The slide rail is located on the inner top of the frame, and the sliding direction of the slide rail is perpendicular to the conveying direction of the conveyor belt. The material taking electric telescopic rod is slidably mounted on the slide rail. The material taking fixing plate is located at the push rod end of the material taking electric telescopic rod. The vacuum suction cup is located at the bottom of the material taking fixing plate. A collection box is also provided on the side of the fabric layer taking mechanism.

[0018] This design automatically retrieves fabric by stacking it in a collection box, then using a vacuum suction cup that moves along a slide rail to pick up the fabric from the collection box and place it on top of the pillowcase.

[0019] In summary, the beneficial effects of this invention are as follows:

[0020] 1. This invention involves placing the pillowcase bottom-up on a pillowcase placement board, then conveying it to various workstations via a conveyor belt to complete the filling of the pillowcase with lavender powder. This ensures that each groove is filled with lavender powder, while preventing omissions caused by manual installation, thus improving work efficiency. The finished pillowcases promote sleep through the lavender powder and also have antibacterial properties.

[0021] 2. This invention utilizes the rotation of a pulley to drive a shaped annular belt to rotate along the pulley's direction, thereby moving the uniform discharge box. When the lower feed tube moves above the first receiving tube, the uniform discharge box discharges material into the receiving tube, then stops discharging until it moves to the next receiving tube, at which point it discharges again. The uniform discharge box continues to follow the shaped annular belt, moving sequentially above each receiving tube until the material falls into each tube, then stops discharging and returns to its original position. Subsequently, each automatic opening and closing sealing plate automatically opens, allowing material to fall into the filling groove. The automatic opening and closing sealing plate then closes, turning the receiving tube into a pressing column. The fixing plate moves down via a pressing electric push rod, pressing and compacting the filling groove filled with material, thus completing the automatic filling and pressing process. This eliminates the need for manual filling and pressing, making it more precise. Simultaneously, the material dropping and pressing are completed in one area, ensuring that the material is filled without occupying space, and guaranteeing that the finished product has sufficient hardness to form the massage protrusion.

[0022] 3. This invention uses a fan to collect excess lavender powder through a collection hood into a powder collection tank, preventing excess lavender particles from remaining on the pillowcase and causing a grainy texture after subsequent spray painting and hot pressing.

[0040] The health-functional pillowcase 3 produced by this device has several filling grooves 31 formed at the bottom. The filling grooves 31 protrude from the upper surface of the health-functional pillowcase 3 to form massage protrusions. The filling grooves 31 are filled with lavender powder 32. The bottom of the health-functional pillowcase 3 is laminated with a health-functional fabric layer 4. Both the health-functional pillowcase 3 and the health-functional fabric layer 4 are woven from health-functional fibers and textile fibers. The health-functional fibers are made by melting and spinning a mixture of PET polyester chips, tourmaline powder and nano far-infrared ceramic powder.

[0041] Working principle: such as Figure 1-10 As shown, when the pillowcase composite device 6 is in use, lavender powder is placed into the storage box 901 in advance. The rotation of the pulleys 645 of the primary automatic powder feeding mechanism 64 and the secondary automatic powder feeding mechanism 65 drives the irregular ring belt 644 to rotate along the direction of the pulleys 645, thereby driving the uniform discharge box 90 to move. When the lower feed pipe 642 moves above the first receiving pipe 643, the spiral conveyor 903 rotates to push the powder in the storage box 901 to be output evenly. The material falls into the receiving pipe 643 through the discharge pipe. Then the spiral conveyor 903 stops rotating, and the material stops being discharged. Then the uniform discharge box 90 moves to the next receiving pipe 643, and the uniform discharge box 90 discharges again. The uniform discharge box 90 continues to follow the irregular ring belt 644 to move to the top of each receiving pipe 643 in sequence until the material falls into each receiving pipe. Then the discharge stops, and the uniform discharge box returns to its position through the irregular ring belt 644, so that the lavender powder preparation is complete.

[0042] Afterwards, the pillowcase with the filling groove 31 is placed on the pillowcase placement plate 63 with the bottom facing upwards. Then, the filling groove 31 falls into the groove 632. When the pillowcase placement plate 63 moves to the bottom of the automatic powder feeding mechanism 64, each automatic opening and closing sealing plate 60 automatically opens, and the material falls into the filling groove 31. Then, the automatic opening and closing sealing plate closes, so that the receiving pipe 643 becomes a pressing column. The fixing plate 646 moves down by pressing the electric push rod 647 to press and fill the filling groove filled with material. Then, the fixing plate 646 rises back to its original position by pressing the electric push rod 647.

[0043] Then, the pillowcase placement plate 63 moves to the underside of the secondary powder automatic feeding mechanism 65 via the conveyor belt. The automatic opening and closing sealing plate 60 of the secondary powder automatic feeding mechanism opens automatically, and the material falls into the filling groove 31. Then, the automatic opening and closing sealing plate closes, making the receiving pipe 643 a pressing column. The fixing plate 646 moves down by pressing the electric push rod 647 to press and fill the filling groove filled with material. Then, the residual powder collection mechanism 80 starts to work to remove the excess lavender powder on the pillowcase. Then, the fixing plate 646 of the secondary powder automatic feeding mechanism rises back to its original position by pressing the electric push rod 647.

[0044] The conveyor belt then moves the pillowcase placement plate 63 to below the glue spraying mechanism 66 for glue spraying. After glue spraying, it moves to the fabric layer picking mechanism 67, where a vacuum suction cup places the fabric on top of the pillowcase. Then it moves to the hot pressing mechanism 68 for hot pressing. After drying and cooling, the pillowcase is automatically laminated, improving efficiency.
