Description

Technical Field

[0001] This utility model relates to the field of pillow core processing technology, and in particular to a filling structure for pillow core processing. Background Technology

[0002] The pillow core is the core component of a pillow. It is located inside the pillow and is used for filling and support to provide a comfortable sleep experience. During the manufacturing process of the pillow core, it needs to be filled with filling materials such as fibers and down.

[0003] Currently, when filling pillow cores, the pillowcase is mostly placed manually below the outlet. The pillowcase cannot be automatically positioned, which is labor-intensive and results in low work efficiency. Furthermore, manual handling can easily lead to fatigue after a long time, and if it is accidentally dropped, the filling material will spill out, making cleaning very inconvenient.

[0004] Existing patent (publication number: CN222922903U) discloses a quantitative filling device for pillow core processing, including a filling machine. A base is provided on one side of the filling machine, and a top seat is mounted on the top of the base via two frame plates. A filling tube installed on one side of the filling machine passes through the top seat, and a lifting tube is slidably connected to the outside of the filling tube. This utility model, through the design of a clamping mechanism, opens the upper opening of the pillow core cover during filling and then fits it against the inner wall of the outer clamping plate. Then, an electric actuator is activated, driving the lifting tube downwards. During the downward movement, a drive mechanism drives a slider to slide along the slide rail inside the slide plate and compress a spring, thereby displacing the inner clamping plate towards the outer clamping plate. Finally, after the lifting tube descends to the filling position, the inner clamping plate presses against the pillow core cover that is fitted against the outer clamping plate. At this point, the filling can be started by releasing the hand. This eliminates the need for continuous manual holding during filling, effectively improving filling efficiency and stability.

[0005] To address the aforementioned issues, existing patents offer solutions that can clamp and fix the pillow core during the filling process, eliminating the need for manual handling. However, after clamping and fixing the pillow core, there is a large unsealed space between the filling opening and the filling tube. As a result, the filling material, such as easily dispersed fibers and down, can easily scatter during the filling process. This not only leads to waste of filling material but also impacts the processing environment.

[0006] Therefore, a filling structure for pillow core processing is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a filling structure for pillow core processing, which can solve the problem that although existing methods can clamp and fix the pillow core during the filling process to achieve the goal of eliminating the need for manual handling of the pillow core, there is still a large space between the filling opening and the filling tube of the pillow core after clamping and fixing the pillow core. This space is not sealed, so the filling material is easy to scatter during the filling process. For example, easily scattered filling materials such as fibers and down will not only cause waste of filling materials, but also affect the processing environment.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a filling structure for pillow core processing, comprising a filling machine body and a filling tube, wherein a pillow core fixing component is provided at the filling port of the filling tube, and mounting components are provided on the front and rear sides of the top of the pillow core fixing component, and an auxiliary support component is provided at the bottom of the pillow core fixing component;

[0009] The pillow core fixing assembly includes a fixing plate, which is sleeved on the surface of the filling opening of the filling tube. The surface of the fixing plate has a groove, and an annular airbag is fixedly connected to the inner wall of the groove. An air inlet pipe is connected to the left side of the top of the annular airbag, and the other end of the air inlet pipe extends to the left side of the top of the fixing plate. An air inlet solenoid valve is installed in the air inlet pipe. An exhaust pipe is connected to the right side of the top of the annular airbag, and the other end of the exhaust pipe extends to the right side of the top of the fixing plate. An exhaust solenoid valve is installed in the exhaust pipe. Arc-shaped baffles that cooperate with the annular airbag are fixedly connected to the front and rear sides of the fixing plate.

[0010] Preferably, the mounting assembly includes a first fixing block and a second fixing block, wherein the first fixing block is fixedly connected to the fixing plate on the side near the fixing plate, and the second fixing block is fixedly connected to the filling tube on the side near the filling tube.

[0011] Preferably, a throttle is provided on the side of the first fixing block away from the second fixing block, and a fixing screw is fixedly connected to the side of the throttle near the first fixing block. The other end of the fixing screw passes through the first fixing block and extends into the inner cavity of the second fixing block.

[0012] Preferably, the first fixing block has a threaded hole on the side near the throttle that is used to cooperate with the fixing screw, and the second fixing block has a threaded groove on the side near the first fixing block that is used to cooperate with the fixing screw. The surface of the fixing screw is connected to the inner wall of the threaded hole and the inner wall of the threaded groove by threads.

[0013] Preferably, the auxiliary support assembly includes a fixed frame, the side of the fixed frame near the base of the filling machine body is fixedly connected to the base of the filling machine body, an electric lifting rod is fixedly connected to the right side of the bottom of the fixed frame, and the output rod of the electric lifting rod extends through to the top of the fixed frame and is fixedly connected to a support plate.

[0014] Preferably, a through hole is provided on the right side of the bottom of the fixing frame for use with the electric lifting rod, and the output rod surface of the electric lifting rod is slidably connected to the inner wall of the through hole.

[0015] Preferably, a sealing ring is fixedly connected to the inner wall of the fixed plate, and the inner side of the sealing ring is in close contact with the surface of the filling tube.

[0016] Preferably, a control panel is provided on the right side of the front side of the filling machine body, and a support frame is fixedly connected to the bottom of the control panel. The bottom of the support frame is fixedly connected to the base of the filling machine body.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a pillow core fixing component, this application can open and fix the filling port of the pillow core when filling it. After fixing, the filling port of the pillow core and the filling tube can be sealed without leaving gaps. This can effectively prevent the filling material from scattering during the filling process, avoiding waste of filling material and impact on the processing environment.

[0019] 2. This application allows for the installation and fixing of the pillow core fixing component and the filling tube through the setting of the installation component. The fixing method is relatively convenient to operate and allows for easy disassembly, replacement or maintenance of the pillow core fixing component in the future.

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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A filling structure for pillow core processing includes a filling machine body 1 and a filling tube 2. A pillow core fixing component 3 is provided at the filling port of the filling tube 2. Mounting components 4 are provided on the front and rear sides of the top of the pillow core fixing component 3. An auxiliary support component 5 is provided at the bottom of the pillow core fixing component 3.

[0029] The pillow core fixing assembly 3 includes a fixing plate 31, which is sleeved on the surface of the filling opening of the filling tube 2. The surface of the fixing plate 31 has a groove 32, and the inner wall of the groove 32 is fixedly connected to an annular airbag 33. An air inlet pipe 34 is connected to the left side of the top of the annular airbag 33. The other end of the air inlet pipe 34 extends to the left side of the top of the fixing plate 31. An air inlet solenoid valve 35 is provided in the air inlet pipe 34. An exhaust pipe 36 is connected to the right side of the top of the annular airbag 33. The other end of the exhaust pipe 36 extends to the right side of the top of the fixing plate 31. An exhaust solenoid valve 37 is provided in the exhaust pipe 36. Arc-shaped baffles 38 that cooperate with the annular airbag 33 are fixedly connected to the front and rear sides of the fixing plate 31.

[0030] In this embodiment: by setting up a filling machine body 1, a filling tube 2, a pillow core fixing component 3, an installation component 4, and an auxiliary support component 5, during use, the filling machine body 1 and the filling tube 2 can fill the pillow core with filling material. The pillow core fixing component 3 can open and fix the filling opening of the pillow core during filling, and after fixing, the filling opening of the pillow core and the filling tube 2 can be sealed without leaving gaps, thereby effectively preventing the filling material from scattering during the filling process, avoiding waste of filling material and impact on the processing environment. The installation component 4 can install and fix the pillow core fixing component 3 to the filling tube 2. The fixing method is relatively convenient to operate, and the pillow core fixing component 3 can be easily disassembled, replaced, or maintained later. The auxiliary support component 5 can provide auxiliary support for the pillow core during the filling process, preventing the pillow core from sagging or deforming due to gravity during filling.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the installation component 4 includes a first fixing block 41 and a second fixing block 42. The side of the first fixing block 41 closest to the fixing plate 31 is fixedly connected to the fixing plate 31, and the side of the second fixing block 42 closest to the filling tube 2 is fixedly connected to the filling tube 2.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a handle 43 is provided on the side of the first fixing block 41 away from the second fixing block 42. A fixing screw 44 is fixedly connected to the side of the handle 43 close to the first fixing block 41. The other end of the fixing screw 44 passes through the first fixing block 41 and extends into the inner cavity of the second fixing block 42.

[0033] Specifically, such as Figure 2 , Figure 4 As shown, the first fixing block 41 has a threaded hole 45 on the side near the throttle 43 that is used to cooperate with the fixing screw 44, and the second fixing block 42 has a threaded groove 46 on the side near the first fixing block 41 that is used to cooperate with the fixing screw 44. The surface of the fixing screw 44 is connected to the inner wall of the threaded hole 45 and the threaded groove 46 by threads on the side near the inner wall of the threaded hole 45 and the threaded groove 46 respectively.

[0034] In this embodiment: by setting a first fixing block 41, a second fixing block 42, a handle 43, a fixing screw 44, a threaded hole 45, and a threaded groove 46, in use, the fixing plate 31 is placed on the surface of the filling opening of the filling tube 2 and the position is adjusted. Then, by rotating the handle 43, the handle 43 drives the fixing screw 44 to rotate in the first fixing block 41 and move under the guidance of the threaded hole 45, so that the fixing screw 44 enters the threaded groove 46 of the second fixing block 42, thereby completing the installation and fixing of the fixing plate 31 and the filling tube 2, thus completing the installation and fixing of the entire pillow core fixing assembly 3 and the filling tube 2. The operation is relatively convenient, and disassembly can be performed by reversing the operation, which makes it convenient to disassemble, replace or maintain the pillow core fixing assembly 3 in the future.

[0035] Specifically, such as Figure 1 , Figure 5 As shown, the auxiliary support assembly 5 includes a fixed frame 51. The fixed frame 51 is fixedly connected to the base of the filling machine body 1 on the side near the base of the filling machine body 1. An electric lifting rod 52 is fixedly connected to the right side of the bottom of the fixed frame 51. The output rod of the electric lifting rod 52 extends through to the top of the fixed frame 51 and is fixedly connected to a support plate 53.

[0036] Specifically, such as Figure 5 As shown, a through hole 54 is provided on the right side of the bottom of the fixed frame 51 to cooperate with the electric lifting rod 52. The output rod surface of the electric lifting rod 52 is slidably connected to the inner wall of the through hole 54.

[0037] In this embodiment: by setting up a fixing frame 51, an electric lifting rod 52, a support plate 53, and a through hole 54, the fixing frame 51 can support and fix the electric lifting rod 52 during use. Then, when filling the pillow core, the electric lifting rod 52 can be activated, so that the output rod of the electric lifting rod 52 slides out in the through hole 54 of the fixing frame 51 and drives the support plate 53 to move upward, so that the top of the support plate 53 fits with the bottom of the pillow core, thereby achieving auxiliary support for the pillow core and preventing the pillow core from sagging or deforming due to gravity during filling.

[0038] Specifically, such as Figure 2 , Figure 3 As shown, a sealing ring 6 is fixedly connected to the inner wall of the fixed plate 31, and the inner side of the sealing ring 6 is tightly fitted to the surface of the filling tube 2.

[0039] Specifically, such as Figure 1 As shown, a control panel 7 is provided on the right side of the front side of the filling machine body 1. A support frame 8 is fixedly connected to the bottom of the control panel 7, and the bottom of the support frame 8 is fixedly connected to the base of the filling machine body 1.

[0040] In this embodiment: by setting a sealing ring 6, the inner wall of the fixed plate 31 and the surface of the filling tube 2 can be sealed to prevent the filling material from leaking from the inner wall of the fixed plate 31 and the surface of the filling tube 2. By setting a control panel 7, the entire device can be easily operated. By setting a support frame 8, the control panel 7 can be supported and fixed.

[0041] Working principle: In use, first install the pillow core fixing assembly 3 at the filling opening of the filling tube 2. The fixing plate 31 can be placed on the surface of the filling opening of the filling tube 2 and adjusted in position. Then, by rotating the handle 43, the fixing screw 44 rotates within the first fixing block 41 and moves under the guidance of the threaded hole 45, allowing the fixing screw 44 to enter the threaded groove 46 of the second fixing block 42. This completes the installation and fixing of the fixing plate 31 and the filling tube 2, thus completing the installation and fixing of the entire pillow core fixing assembly 3 and the filling tube 2. The operation is relatively convenient; disassembly can be performed by reversing the operation, facilitating subsequent adjustments to the pillow core. The pillow core fixing component 3 is disassembled, replaced, or maintained. After the pillow core fixing component 3 is installed, the air inlet pipe 34 of the annular airbag 33 is connected to an electric air pump or other inflation equipment. When filling the pillow core, the filling opening of the pillow core is placed on the surface of the fixing plate 31. Then, the air inlet solenoid valve 35 of the air inlet pipe 34 is opened through the control panel 7, and the inflation equipment is turned on to inflate the annular airbag 33 through the air inlet pipe 34. The annular airbag 33 will expand under the action of air pressure, opening the filling opening of the pillow core and tightly fitting it to the inner wall of the pillow core. With the limiting effect of the arc-shaped baffle 38, the pillow core can be firmly fixed. Since the fixing plate 31 is a sleeve The filling tube 2 is sealed with a sealing ring 6, and the annular airbag 33 is fixedly connected to the groove 32 on the surface of the fixing plate 31. The annular airbag 33 is tightly fitted to the inner wall of the pillow core, so that after fixing, the filling port of the pillow core and the filling tube 2 can be sealed without leaving gaps. This effectively prevents the filling material from scattering during the filling process, avoiding waste of filling material and impact on the processing environment. After the pillow core is fixed, the inflation device is turned off by the control panel 7 to stop inflation and the air inlet solenoid valve 35 is closed. Then, the filling machine body 1 can be started by the control panel 7 to fill the pillow core using the filling tube 2. During the filling process, the electric lifting rod 52 can be activated by operating it. The output rod of the electric lifting rod 52 slides out of the through hole 54 of the fixing frame 51 and drives the support plate 53 to move upward, so that the top of the support plate 53 fits with the bottom of the pillow core. This provides auxiliary support for the pillow core and prevents it from sagging or deforming due to gravity during filling. After filling is completed, the exhaust solenoid valve 37 on the exhaust pipe 36 is opened by operating the control panel 7 to release the air pressure in the annular airbag 33. The annular airbag 33 will contract, thus canceling the opening and fixing of the pillow core. Then, the filled pillow core can be removed from the surface of the fixing plate 31.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
