Description

Technical Field

[0001] This invention relates to the field of pillow core preparation technology, and in particular to a preparation apparatus and process for a multi-layered pillow core. Background Technology

[0002] The field of intelligent packaging and conveying is evolving towards automation, flexibility, and high precision, with multi-station collaboration, online detection, and adaptive control becoming mainstream trends. Technologies such as magnetic drive conveying and machine vision recognition have emerged in the industry, enabling high-speed positioning and quality assessment, while modular design enhances the flexibility of production line changes. The overall trend is one of upgrading from single-machine automation to full-process digitalization, and from rigid production lines to flexible manufacturing, providing a technological foundation for the efficient packaging of home textile products such as multi-layered pillow cores.

[0003] For intelligent packaging and conveying of multi-layered pillow cores, existing solutions still have key shortcomings: First, the linkage between the conveying and pressing mechanisms is insufficient, which can easily lead to separation between the layers of blanks, affecting the regularity of subsequent shearing and packaging. Second, the matching accuracy between intermittent conveying and shearing actions is lacking, making it difficult to ensure the uniformity of the pillow core semi-finished product size and reducing the finished product qualification rate. Third, there is a lack of flexible adaptation mechanisms for multi-layered materials, and the adjustment of the model is time-consuming, which cannot meet the needs of intelligent production with multiple specifications and fast pace. Summary of the Invention

[0014] This invention also proposes a process for preparing a multi-layered pillow core, comprising the following steps: Process step one: Start the servo motor. The servo motor drives the long shaft to rotate at a constant speed through the meshing of the drive gear and the driven gear. The long shaft drives the shearing blade to move up and down in a reciprocating motion through a reciprocating mechanism, drives the first conveyor belt to rotate clockwise intermittently through an intermittent mechanism, and drives the second conveyor belt to rotate continuously clockwise through a chain drive. At the same time, a pair of lower pressure rollers above the first conveyor belt rotate counterclockwise in conjunction with the first roller shaft, and the third conveyor belt above the second conveyor belt rotates counterclockwise in conjunction with the second roller shaft. The operating speed and direction of each component are adjusted to be consistent, ensuring that the shearing blades are aligned with the shearing baffles and that the clamping force of each conveyor belt and roller is moderate, so as to meet the requirements of conveying and shearing multi-layer pillow cores. Process step two: The pre-formed multi-layered pillow core blank, which is composed of multiple filling layers and fabric layers, is laid flat on the top left side of the first conveyor belt to ensure that the blank is laid flat without wrinkles or deviation. The width of the blank matches the width of the first conveyor belt and the shearing baffle to ensure the regularity of subsequent pressing and shearing. Process Step 3: The first conveyor belt rotates clockwise intermittently under the drive of the intermittent mechanism, driving the multi-layer pillow core blank to be smoothly conveyed to the right. During the conveying process, a pair of counterclockwise rotating downward pressure rollers above the first conveyor belt operate synchronously, applying downward pressure to the multi-layer pillow core blank conveyed below, tightly bonding the multi-layer blanks, eliminating gaps between layers, ensuring that the multi-layer structure of the pillow core is firmly bonded, and avoiding separation between layers during subsequent shearing and conveying processes. Process step four: When the multi-layer pillow core blank is intermittently conveyed to the right end by the first conveyor belt, passes through the shearing baffle and extends to the preset shearing length, the first conveyor belt stops running; at this time, the reciprocating mechanism driven by the long shaft drives the shearing blade to move downward. The shearing blade and the shearing baffle cooperate to precisely shear the multi-layer pillow core blank, and obtain a multi-layer structure pillow core semi-finished product of preset size; after shearing, the shearing blade is reset upward under the action of the reciprocating mechanism to prepare for the next shearing; Step 5: The sheared multi-layer pillow core semi-finished product falls to the left side of the top surface of the second conveyor belt under its own weight and the thrust of the subsequent intermittent conveying of the first conveyor belt; the second conveyor belt rotates continuously clockwise under the drive of the chain drive, driving the pillow core semi-finished product to the right; during the conveying process, the third conveyor belt above the second conveyor belt rotates counterclockwise synchronously, applying downward pressure to the pillow core semi-finished product, further regularizing the shape of the pillow core, ensuring that the multi-layer structure of the pillow core is tightly bonded and of uniform thickness, and avoiding problems such as edge lifting and loosening between layers; Process step six: When the shaped multi-layered pillow core semi-finished product is conveyed to the right end outlet by the second conveyor belt, the operator or the supporting collection mechanism collects and sorts the finished pillow core uniformly to complete the preparation of a single batch of multi-layered pillow core; the subsequent steps are repeated to realize the continuous preparation of multi-layered pillow cores; During the process, the intermittent rotation amplitude of the first conveyor belt and the pressing force of the lower roller and the third conveyor belt can be adjusted according to the preset size and thickness of the multi-layered pillow core to ensure that the finished pillow core is dimensionally accurate, the multi-layers are firmly bonded, and it meets the product quality requirements.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention improves the linkage of intelligent packaging conveying by synchronously driving the conveying, shearing, and straightening mechanisms with a single power source, realizing the coordinated operation of each process without the need for multiple power source configurations, reducing the cost of intelligent production lines, while ensuring precise matching of conveying and shearing rhythms, laying an efficient foundation for intelligent packaging conveying; 2. This invention optimizes the adaptability and stability of intelligent packaging conveying, and can flexibly adjust the conveying gap and clamping force to adapt to different specifications of pillow cores. During conveying, it eliminates the gap between blank layers, regularizes the shape of semi-finished products, avoids layer separation and edge lifting, and ensures the consistency of products conveyed by intelligent packaging. In summary, this invention solves the problems of low efficiency, poor adaptability, and uneven finished product quality in intelligent packaging conveying by means of mechanism linkage, precise control, and flexible adaptation, realizing intelligent collaborative conveying throughout the entire pillow core preparation process, and improving the automation level and finished product qualification rate of intelligent packaging conveying.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: This example provides a fabrication apparatus and process for a multi-layered pillow core. See [link to example]. Figures 1 to 7 Specifically, it includes a base plate 100, a pair of first side plates 101 symmetrically distributed front and back are fixedly provided on the left side of the top surface of the base plate 100, a first conveyor belt 104 rotating clockwise is installed between the pair of first side plates 101, and a pair of lower pressure rollers 107 rotating counterclockwise are symmetrically installed above the first conveyor belt 104. A pair of second side plates 200 symmetrically distributed front and back are fixedly installed on the right side of the top surface of the base plate 100. A second conveyor belt 203 rotating clockwise is installed between the pair of second side plates 200. A third conveyor belt 207 rotating counterclockwise is installed above the second conveyor belt 203. A shearing baffle 111 is fixedly installed between the right ends of a pair of first side plates 101. An L-shaped side plate 300 and a third side plate 302 are fixedly installed on the right side of the top surface of the pair of first side plates 101 respectively. A shearing blade 308 is installed between the L-shaped side plate 300 and the third side plate 302 to perform shearing operations in conjunction with the shearing baffle 111. The shearing baffle 111 and the shearing blade 308 cooperate with each other to provide a precise shearing benchmark for the multi-layer structure pillow core blank, ensuring that the dimensions of the semi-finished pillow core are uniform after shearing. A long shaft 402 is rotatably installed between the top ends of the L-shaped side plate 300 and the third side plate 302. The long shaft 402 drives the shearing blade 308 to move up and down reciprocally through a reciprocating mechanism. The long shaft 402 drives the first conveyor belt 104 to rotate clockwise intermittently through an intermittent mechanism. The long shaft 402 drives the second conveyor belt 203 to rotate continuously clockwise through a chain drive.

[0019] In the specific implementation process, such as Figure 4 and Figure 5 As shown, a pair of first rollers 102 are rotatably inserted between a pair of first side plates 101, and a first roller 103 is fixedly sleeved in the middle of each first roller 102. The two sides of the first conveyor belt 104 are sleeved on the pair of first rollers 103. The pair of first side plates 101 provide stable support for the first rollers 102 and the lower pressure roller 106. Each pressure roller 107 has a through-distributed pressure roller shaft 106 fixedly inserted in the middle. The top edges of a pair of first side plates 101 are respectively provided with a pair of first notches 110 for the pressure roller shaft 106 to slide. The first notches 110 provide sliding space for the pressure roller shaft 106. With the linkage structure of the first swing arm 105, it can be adapted to the conveying of multi-layer structure pillow core blanks of different thicknesses. Two pairs of obliquely symmetrically distributed first swing arms 105 are provided on the outer side of a pair of first side plates 101. The two ends of each first roller shaft 102 are respectively rotatably inserted into the bottom end of the corresponding first swing arm 105, and the two ends of each lower pressure roller shaft 106 are respectively rotatably inserted into the top end of the corresponding first swing arm 105. Each first roller shaft 102 has a first gear 108 fixedly sleeved at its rear end, and each lower roller shaft 106 has a second gear 109 fixedly sleeved at its rear end. Adjacent first gears 108 and second gears 109 mesh with each other. The first gear 108 and the second gear 109 mesh and work together to achieve the simultaneous clockwise rotation of the first roller shaft 102 and the clockwise rotation of the first conveyor belt 104, while driving the lower pressure roller shaft 106 to rotate the lower pressure roller 107 counterclockwise, so that the first conveyor belt 104 and the lower pressure roller 107 form a counter-rotating state. During the conveying of the multi-layered pillow core blank, a continuous clamping force is applied to effectively eliminate the gaps between the blank layers, ensure that the multi-layered structure is firmly bonded, and avoid the problem of interlayer separation during subsequent shearing.

[0020] In the specific implementation process, such as Figure 4 and Figure 5As shown, a pair of second rollers 201 are rotatably inserted between a pair of second side plates 200, and a second roller 202 is fixedly sleeved in the middle of each second roller 201. The two sides of the second conveyor belt 203 are respectively sleeved on a pair of second rollers 202. The second side plates 200 provide stable support for the second rollers 201 and the driven shaft 210. Above the second conveyor belt 203, there is a pair of parallel third rollers 205. The top edges of the pair of second side plates 200 are respectively provided with a pair of second notches 204 for the third rollers 205 to slide. A third roller 206 is fixedly sleeved in the middle of each third roller 205. The two sides of the third conveyor belt 207 are respectively sleeved on the pair of third rollers 206. The second notches 204 provide sliding space for the third rollers 205. With the support and linkage of the second swing arm 211, the distance between the third conveyor belt 207 and the second conveyor belt 203 can be flexibly adjusted to adapt to the standardization operation of pillow core semi-finished products of different thicknesses. Two pairs of obliquely parallel second swing arms 211 are provided on the outer side of a pair of second side plates 200. The two ends of each third roller shaft 205 are rotatably inserted into the top of the corresponding second swing arm 211. A pair of driven shafts 210 are rotatably inserted into the outer side of a pair of second side plates 200. The two ends of the second roller shaft 201 on the right side and the pair of driven shafts 210 are rotatably inserted into the bottom of the corresponding second swing arm 211. The rear end of the second roller shaft 201 located on the right is fixedly fitted with a third gear 208, and the rear end of the third roller shaft 205 located on the right is fixedly fitted with a fourth gear 209. The third gear 208 and the fourth gear 209 mesh with each other and are linked together, so that the second roller shaft 201 drives the second conveyor belt 203 to rotate clockwise, while simultaneously driving the third roller shaft 205 to drive the third conveyor belt 207 to rotate counterclockwise, so that the second conveyor belt 203 and the third conveyor belt 207 form a counter-rolling shape. The semi-finished pillow core is then compressed and straightened a second time to effectively prevent problems such as curling edges and loosening between layers, ensuring uniform pillow core thickness.

[0021] It should be noted that: such as Figure 6 and Figure 7 As shown, a driven gear 403 is fixedly sleeved at the front end of the long shaft 402, and a servo motor 400 is fixedly installed at the left end of the L-shaped side plate 300. A drive gear 401 is fixedly sleeved at the end of the output shaft of the servo motor 400. The drive gear 401 and the driven gear 403 are meshed and connected. The servo motor 400 provides a stable power source for the long shaft 402 through the meshing of the drive gear 401 and the driven gear 403, realizing the synchronous drive of the reciprocating mechanism, the intermittent mechanism and the chain drive, improving the automation linkage of the device and reducing the cost investment of multiple power source configurations. The chain drive includes a chain belt 405. A drive sprocket is fixedly sleeved at the rear end of the long shaft 402, and a driven sprocket is fixedly sleeved at the rear end of the second roller shaft 201 located on the left. The chain belt 405, which is synchronously connected to the drive sprocket and the driven sprocket, meshes and is connected to the chain belt 405. The meshing transmission structure of the drive sprocket, the driven sprocket and the chain belt 405 realizes the stable transmission of power from the long shaft 402 to the second roller shaft 201, ensuring that the second conveyor belt 203 rotates continuously and at a uniform speed, providing continuous conveying power for the sheared pillow core semi-finished product, and adapting to the rhythm requirements of the subsequent straightening and collection processes.

[0022] In the specific implementation process, such as Figure 6 and Figure 7 As shown, the reciprocating mechanism includes an L-shaped bracket 307 and an eccentric cam 404. A pair of fixed lugs 303 are fixedly installed on the opposite surfaces of the L-shaped side plate 300 and the third side plate 302. A fixed slide rod 304 is slidably inserted into the inner end of each fixed lug 303. A downward stop block 305 is fixedly installed at the bottom end of each fixed slide rod 304. A tension spring 306 is sleeved on the upper half of each fixed slide rod 304. The fixed lugs 303 play a guiding and limiting role for the fixed slide rod 304. The tension spring 306 can drive the fixed slide rod 304 and the L-shaped bracket 307 to return to the upper position, so that the L-shaped bracket 307 is always tightly abutting against the outer surface of the eccentric cam 404. Each fixed slide bar 304 has an L-shaped bracket 307 fixedly installed at its top. The top edge of the shearing blade 308 is fixedly connected to the bottom of a pair of L-shaped brackets 307. A pair of eccentric cams 404 are fixedly sleeved on the long shaft 402. The bottom edge of each eccentric cam 404 slides against the top surface of the L-shaped bracket 307 on the same side. When the long shaft 402 drives the eccentric cam 404 to rotate, the eccentric structure drives the L-shaped bracket 307 to drive the shearing blade 308 to move up and down reciprocally. The lower stop block 305 can press the blank before shearing to avoid the blank from shifting during the shearing process and ensure the accuracy and continuity of the shearing operation.

[0023] In the specific implementation process, such as Figure 6 and Figure 7 As shown, the intermittent mechanism includes a notched disc 408, a limiting pin 409, and an intermittent disc 301. A drive shaft 406 is rotatably inserted into the top and bottom of the L-shaped side plate 300. A drive gear 407 is fixedly sleeved at the front end of the drive shaft 406. A driven gear 403 meshes with the drive gear 407. Notched discs 408 are concentrically distributed on the front side of the drive gear 407. A limiting pin 409 corresponding to the notched portion of the notched disc 408 is fixedly installed on the front side of the drive gear 407. The driven gear 403 meshes with the drive gear 407 to drive the notched disc 408 and the limiting pin 409 to rotate synchronously. An intermittent disk 301 is fixedly sleeved at the front end of the first roller shaft 102 on the right side. The outer surface of the intermittent disk 301 has several alternating arc-shaped notches 309 and U-shaped notches 310. The outer surface of the notched disk 408 cooperates with the arc-shaped notches 309, and the limiting pin 409 cooperates with the U-shaped notches 310. Through the contact and limiting of the notched disk 408 and the arc-shaped notches 309, and the engagement and driving of the limiting pin 409 and the U-shaped notches 310, the intermittent disk 301 drives the first roller shaft 102 on the right side to rotate intermittently. The intermittently rotating first roller 102 drives the first conveyor belt 104 to perform clockwise intermittent conveying, ensuring that the length of the blank conveyed each time is precisely matched with the shearing size of the shearing blade 308, ensuring the dimensional consistency of the pillow core semi-finished product, and at the same time realizing the rhythm coordination of blank conveying and shearing operation.

[0024] The working principle of this embodiment is as follows: Start the servo motor 400, control the output shaft of the servo motor 400 to rotate in the opposite direction, the output shaft of the servo motor 400 drives the drive gear 401 to rotate in the opposite direction synchronously, and the drive gear 401 meshes with and drives the driven gear 403, the long shaft 402, a pair of eccentric cams 404 and the drive sprocket to rotate in the forward direction synchronously. The active sprocket drives the driven sprocket, the corresponding second roller 201, the second roller 202 and the second conveyor belt 203 to rotate synchronously in the forward direction through the chain belt 405, providing continuous conveying power for the sheared pillow core semi-finished product, and adapting to the subsequent straightening and collection process.

[0025] When the second conveyor belt 203 rotates, it synchronously drives the second roller 202, the second roller shaft 201 and the third gear 208 located on the right side to rotate in the forward direction. The third gear 208 meshes and drives the fourth gear 209, the corresponding third roller shaft 205, the third roller 206 and the third conveyor belt 207 to rotate in the reverse direction, so that the second conveyor belt 203 and the third conveyor belt 207 form a reverse rolling state, which prepares for the subsequent pressing and straightening of the pillow core semi-finished product.

[0026] Under the continuous tension of the tension spring 306, the fixed slide bar 304 is driven to slide upward along the fixed lug 303, thereby ensuring that the L-shaped bracket 307 is always tightly abutting against the outer surface of the eccentric cam 404, thus ensuring the continuity of the reciprocating shearing action. When the eccentric cam 404 rotates to the position of pressing down on the L-shaped bracket 307, it will drive the L-shaped bracket 307 and the fixed slide rod 304 to slide down along the fixed ear seat 303. First, the pressing block 305 presses against the multi-layer structure pillow core blank conveyed below to prevent the blank from shifting during shearing. Then, it drives the shearing blade 308 to move down synchronously, and cooperates with the shearing baffle 111 to accurately shear the multi-layer structure pillow core blank to obtain a multi-layer structure pillow core semi-finished product of preset size. After shearing is completed, the eccentric cam 404 continues to rotate, and the tension of the tension spring 306 drives all components to reset upwards. The shearing blade 308 returns to its initial position, preparing for the next shearing operation.

[0027] At the same time, the driven gear 403 meshes with and drives the transmission gear 407, the notched disc 408, and the limiting pin 409 to rotate in the opposite direction along the transmission shaft 406. The notched disc 408 and the limiting pin 409 form an alternating limiting engagement with the arc-shaped notch 309 and the U-shaped notch 310 on the intermittent disc 301, thereby driving the intermittent disc 301, the corresponding first roller 102, the first gear 108, the first roller 103, and the first conveyor belt 104 to rotate intermittently in the forward direction, realizing the intermittent conveying of the multi-layer structure pillow core blank, ensuring that the length of the blank and the shearing size are accurately matched each time, and ensuring the dimensional consistency of the pillow core preparation.

[0028] When the first gear 108 rotates, it meshes with and drives the matched second gear 109, the lower pressure roller shaft 106, and the lower pressure roller 107 to rotate in the forward direction. Since the lower pressure roller 107 and the first conveyor belt 104 rotate in opposite directions, they form a rolling pressing structure. During the conveying process of the multi-layer pillow core blank, a downward pressing force is continuously applied to the blank, which tightly adheres the multi-layer blank, eliminates the gap between layers, avoids the separation between layers during subsequent shearing and conveying, and ensures the preparation quality of the multi-layer pillow core.

[0029] Example 2: Based on Example 1, this example proposes a process for preparing a multi-layered pillow core, including the following steps: Process step one: Start the servo motor 400. The servo motor 400 meshes with the driven gear 403 through the drive gear 401, driving the long shaft 402 to rotate at a constant speed. The long shaft 402 drives the shearing blade 308 to move up and down reciprocally through a reciprocating mechanism, drives the first conveyor belt 104 to rotate clockwise intermittently through an intermittent mechanism, and drives the second conveyor belt 203 to rotate continuously clockwise through a chain drive. Meanwhile, the pair of lower pressure rollers 107 above the first conveyor belt 104 rotate counterclockwise in conjunction with the first roller shaft 102, and the third conveyor belt 207 above the second conveyor belt 203 rotates counterclockwise in conjunction with the second roller shaft 201. The operating speed and direction of each component are adjusted to be consistent, ensuring that the shearing blade 308 is aligned with the shearing baffle 111, and that the clamping force of each conveyor belt and roller is moderate, so as to meet the requirements of multi-layer pillow core conveying and shearing. Process step two: The pre-formed multi-layered pillow core blank, which is composed of multiple filling layers and fabric layers, is laid flat on the top left side of the first conveyor belt 104 to ensure that the blank is laid flat without wrinkles or deviation. The width of the blank matches the width of the first conveyor belt 104 and the shearing baffle 111 to ensure the regularity of subsequent pressing and shearing. Process step three: The first conveyor belt 104 rotates clockwise intermittently under the drive of the intermittent mechanism, driving the multi-layer pillow core blank to be smoothly conveyed to the right. During the conveying process, a pair of counterclockwise rotating downward pressure rollers 107 above the first conveyor belt 104 operate synchronously, applying downward pressure to the multi-layer pillow core blank conveyed below, tightly bonding the multi-layer blank, eliminating gaps between layers, ensuring that the multi-layer structure of the pillow core is firmly bonded, and avoiding separation between layers during subsequent shearing and conveying processes. Process step four: When the multi-layer pillow core blank is intermittently conveyed to the right end by the first conveyor belt 104, passes through the shear baffle 111 and extends to the preset shearing length, the first conveyor belt 104 stops running; at this time, the reciprocating mechanism driven by the long shaft 402 drives the shearing blade 308 to move downward. The shearing blade 308 and the shear baffle 111 cooperate with each other to precisely shear the multi-layer pillow core blank, and obtain a multi-layer structure pillow core semi-finished product of preset size; after shearing, the shearing blade 308 resets upward under the action of the reciprocating mechanism, in preparation for the next shearing; Process step five: The sheared multi-layer pillow core semi-finished product falls to the left side of the top surface of the second conveyor belt 203 under its own weight and the thrust of the subsequent intermittent conveying of the first conveyor belt 104; the second conveyor belt 203 rotates continuously clockwise under the drive of chain drive, driving the pillow core semi-finished product to the right; during the conveying process, the third conveyor belt 207, which rotates counterclockwise above the second conveyor belt 203, operates synchronously, applying downward pressure to the pillow core semi-finished product, further regularizing the shape of the pillow core, ensuring that the multi-layer structure of the pillow core is tightly bonded and of uniform thickness, and avoiding problems such as edge lifting and interlayer loosening; Process step six: When the shaped multi-layered pillow core semi-finished product is conveyed to the right end outlet by the second conveyor belt 203, the operator or the supporting collection mechanism collects and sorts the finished pillow core uniformly to complete the preparation of a single batch of multi-layered pillow core; the subsequent steps are repeated to realize the continuous preparation of multi-layered pillow cores; During the process, the intermittent rotation amplitude of the first conveyor belt 104, the pressing force of the lower roller 107 and the third conveyor belt 207 can be adjusted according to the preset size and thickness of the multi-layered pillow core to ensure that the finished pillow core is dimensionally accurate, the multi-layers are firmly bonded, and it meets the product quality requirements.
