Description

Technical Field

[0001] This invention relates to the field of packaging material production equipment technology, specifically to a process and equipment for die-cutting pearl cotton. Background Technology

[0002] Currently, EPE foam packaging materials are made from large rolls or sheets of raw material through die-cutting. To fit the die-cutting mold size, the rolls or large pieces of raw material need to be pre-cut into pieces slightly larger than the area to be processed in a single operation. These pieces are then fed one by one into the die-cutting machine for die-cutting. The die-cut parts and waste are collected separately for packaging and storage. The entire production line is roughly divided into pre-cutting, die-cutting, sorting, packaging, and transfer stations, each of which requires manual operation. High labor intensity and low work efficiency are major shortcomings of the current process. Summary of the Invention

[0003] The purpose of this invention is to integrate the production process of pearl cotton and provide a seamless pearl cotton die-cutting process and equipment to achieve unmanned and automated production.

[0004] The uninterrupted pearl cotton die-cutting process provided by this invention mainly consists of four major processes: raw material filling, conveying and welding, die-cutting, and final packaging. The specific steps of each process are as follows: A. Filling raw materials A1 Place the roll or sheet material at the feed inlet; A2 The feeding mechanism horizontally centers and stacks the raw materials between the feeding conveyor belts; A3 The feeding mechanism detects the material thickness and adjusts the thickness clamping roller spacing according to the measured thickness.

[0005] B Conveying and Welding The B1 feed conveyor belt continuously feeds in raw materials according to the set linear speed and set production cycle. After B2 detects the cross-section of the material head, the front pressure plate of the welding mechanism presses down on the rear end of the front material block, and the rear conveying mechanism slows down or pauses to create a gap between the two material heads that allows the heating plate to be inserted. The rear pressure plate presses down on the front end of the rear material block and drives the heating plate to be inserted between the two material heads for heating. After the B3 heating plate melts the two material heads, it is quickly moved out between the two material heads; With the B4 rear pressure plate released, the rear conveying mechanism accelerates the conveying to fuse and weld the rear material block with the front material block. The front and rear pressure plates press down on the front and rear end material blocks respectively, keeping the rear material head docking position flat with the front material head. After B5 fusion welding and shaping, the front and rear pressure plates are removed; B6 The welding mechanism maintains synchronization with the speed of the front material block conveyor during the welding process; After completing the welding, the B7 welding mechanism moves back to the standby position.

[0006] C punching When C1 detects that the raw material has entered the punching station, the feeding is paused. C1 drives the die to press down and punch the pearl cotton sheet; C3 lifts the mold and continues feeding.

[0007] D after packaging D1 punched workpieces are transferred into the sorting area; D2a stretches and then cuts the punched workpiece, or D2b cuts directly without stretching, or D2c stretches and then does not cut, or D2d neither stretches nor cuts. D3a sorts and boxes D2a or D2b by individual piece, and D3b rolls D2c or D2d into rolls. D4 seals D3a in a box and D3b in a bag; D5 The packaged finished products are moved off the production line.

[0008] In the aforementioned process, A1 and D5 can be transported back and forth by robots, enabling the entire production line to achieve unmanned and fully automated production.

[0009] An uninterrupted EPE foam die-cutting equipment that realizes the aforementioned uninterrupted EPE foam die-cutting process includes: a feeding robot, a feeding mechanism, a feeding mechanism, a moving welding mechanism, a die-cutting mechanism, a post-packaging mechanism, and an unloading robot.

[0010] The feeding mechanism includes a feeding reel, a feeding conveyor belt, a feeding monitoring component, and a thickness clamping roller. The feeding mechanism mainly realizes the A-stage raw material loading process, and the coordination method is as follows: A. Place the roll material on the feeding reel or the sheet material on the feeding conveyor belt at the inlet; A. The feeding mechanism horizontally centers and stacks the raw materials between the feeding conveyor belts; A. The feeding monitoring component of the feeding mechanism detects the material thickness and adjusts the thickness clamping roller spacing according to the measured thickness.

[0011] The feeding mechanism can be configured as one or more groups, each group of feeding mechanisms is equipped with a feeding belt, and the feeding width of the feeding belt is consistent with that of the feeding conveyor belt; the feeding mechanism and the moving welding mechanism cooperate to realize the conveying and welding process.

[0012] The mobile welding mechanism includes a heating plate, a shaping pressure plate, and a welding frame. The welding frame includes a portal-shaped sliding support, a heating plate lifting support, and a pressure plate lifting support. Both the heating plate lifting support and the pressure plate lifting support are movably mounted on the portal-shaped sliding support. The pressure plate lifting support includes a front pressure plate lifting support and a rear pressure plate lifting support, which are respectively positioned on the front and rear sides of the heating plate lifting support. A translation drive motor drives the welding frame to move horizontally back and forth between a first feeding mechanism and a second feeding mechanism. The heating plate is fixed on the heating plate lifting support, and a heating plate drive motor drives the heating plate lifting support to move up and down. The shaping pressure plate includes a front shaping pressure plate and a rear shaping pressure plate, which are fixedly connected to the front pressure plate support and the rear pressure plate support, respectively. A front pressure plate drive motor drives the front pressure plate support to move up and down, and a rear pressure plate drive motor drives the rear pressure plate support to move up and down. A cross-section detection mechanism is provided on the portal-shaped sliding support.

[0013] When the mobile welding mechanism is in standby mode, the welding frame is located at the front end of the feeding mechanism. The feeding mechanism synchronously transports the pearl cotton sheet through the gantry-shaped translation bracket. After the cross-section detection mechanism detects that the cross-section has moved to the welding area, the front shaping pressure plate descends to press down on the rear end of the front material block. The feeding mechanism slows down or pauses, causing the cross-section to separate into a gap that allows the heating plate to be inserted. The rear shaping pressure plate descends to press down on the front end of the rear material block. The heating plate is inserted into the gap between the two material blocks to simultaneously heat the rear end of the front material block and the front end of the rear material block. After both end faces are melted, the welding process continues. The hot plate rises away from the connection position, the rear shaping plate rises to release the front end of the rear material block, the feeding mechanism accelerates forward, so that the front end of the rear material block quickly comes into contact with the rear end of the front material block for welding, and at the same time the rear shaping plate descends to press the front end of the rear material block until the welded part cools and sets. The front shaping plate and the rear shaping plate rise simultaneously to leave the welding position. During the welding process, the welding frame moves forward synchronously with the feeding mechanism under the drive of the translation drive motor. After the welding is completed, the welding frame moves backward under the drive of the translation drive motor and returns to the welding standby position.

[0014] To facilitate the smooth insertion of the heating plate into the gap between the pearl cotton sections, guide slopes can be set on both sides of the lower part of the heating plate.

[0015] After the raw materials pass through the welding and feeding mechanism, they enter the punching mechanism. The corresponding molds are installed on the stamping plate to perform C-cutting processing on the pearl cotton. The punched parts are then further transported to the finishing and packaging mechanism for the corresponding D-finishing and packaging process.

[0016] The final packaging mechanism is equipped with a stretching component, a cutting component, a boxing component, and a finished product roll. Depending on the processing requirements, it can be selected whether to stretch or cut, so that the punched workpiece can be stretched and then cut, or cut directly without stretching, and then sorted, boxed, and sealed by individual pieces; or stretched without cutting, or rolled into a roll bag without stretching or cutting, and then transported off the line by the unloading robot.

[0017] The present invention uses the above-mentioned solution to realize the uninterrupted pearl cotton die-cutting process and equipment, which can realize unmanned and automated production and greatly improve work efficiency. Attached Figure Description

Detailed Implementation

[0019] The uninterrupted pearl cotton die-cutting process provided by this invention mainly consists of four major processes: raw material filling, conveying and welding, die-cutting, and final packaging. The specific steps of each process are as follows: A. Filling raw materials A1 Place the roll or sheet material into the feed inlet; The A2 feeding mechanism horizontally centers and stacks the raw materials between the feeding conveyor belts; The A3 feeding mechanism detects the material thickness and adjusts the thickness clamping roller spacing based on the measured thickness.

[0020] B Conveying and Welding The B1 feed conveyor belt continuously feeds in raw materials according to the set linear speed and set production cycle. After B2 detects the cross-section of the material head, the front pressure plate of the welding mechanism presses down on the rear end of the front material block, and the rear conveying mechanism slows down or pauses to create a gap between the two material heads that allows the heating plate to be inserted. The rear pressure plate presses down on the front end of the rear material block and drives the heating plate to be inserted between the two material heads for heating. After the B3 heating plate melts the two material heads, it is quickly moved out between the two material heads; With the B4 rear pressure plate released, the rear conveying mechanism accelerates the conveying to fuse and weld the rear material block with the front material block. The front and rear pressure plates press down on the front and rear end material blocks respectively, keeping the rear material head docking position flat with the front material head. After B5 fusion welding and shaping, the front and rear pressure plates are removed; B6 The welding mechanism maintains synchronization with the speed of the front material block conveyor during the welding process; After completing the welding, the B7 welding mechanism moves back to the standby position.

[0021] C punching When C1 detects that the raw material has entered the punching station, the feeding is paused. C1 drives the die to press down and punch the pearl cotton sheet; C3 lifts the mold, and feeding continues.

[0022] D after packaging D1 punched workpieces are transferred into the sorting area; D2a stretches and then cuts the punched workpiece, or D2b cuts directly without stretching, or D2c stretches and then does not cut, or D2d neither stretches nor cuts. D3a sorts and boxes D2a or D2b by individual piece, and D3b rolls D2c or D2d into rolls. D4 seals D3a in a box and D3b in a bag; D5 The packaged finished products are moved off the production line.

[0023] In the aforementioned process, A1 and D5 can be transported back and forth by robots, enabling the entire production line to achieve unmanned and fully automated production.

[0024] like Figure 1 and Figure 2 As shown, an uninterrupted EPE cotton die-cutting equipment for realizing the aforementioned uninterrupted EPE cotton die-cutting process includes: a feeding robot, a feeding mechanism 1, a first feeding mechanism 2, a moving welding mechanism 3, a second feeding mechanism 4, a die-cutting mechanism 5, a post-packaging mechanism 6, and a unloading robot.

[0025] The feeding mechanism 1 includes a feeding reel 11, a feeding conveyor belt 12, a feeding monitoring component 13, and a thickness clamping roller 14. The feeding mechanism 1 mainly realizes the raw material loading process A, and the cooperation method is as follows: A1 Place the roll material on the feeding reel 11 or the sheet material on the feeding conveyor belt 12 at the inlet; A2 The feeding mechanism 1 horizontally centers and stacks the raw materials between the feeding conveyor belts 12; A3 The feeding monitoring component 13 of the feeding mechanism detects the material thickness and adjusts the spacing of the thickness clamping rollers 14 according to the measured thickness.

The first feeding mechanism 2, the moving welding mechanism 3 and the second feeding mechanism 4 cooperate to realize the B conveying and welding process. The first feeding mechanism 2 is equipped with a first feeding belt 21 and the second feeding mechanism 4 is equipped with a second feeding belt 41. The feeding width of the first feeding belt 21 and the second feeding belt 41 is the same as that of the feeding conveyor belt 12.

[0027] The movable welding mechanism 3 includes a heating plate 31, a shaping pressure plate 32, and a welding frame 33. The welding frame 33 includes a portal-shaped sliding support 331, a heating plate lifting support 332, and a pressure plate lifting support 333. The heating plate lifting support 332 and the pressure plate lifting support 333 are both vertically and vertically mounted on the portal-shaped sliding support 331. The pressure plate lifting support 333 includes a front pressure plate lifting support 3331 and a rear pressure plate lifting support 3332, which are respectively located on the front and rear sides of the heating plate lifting support 332.

The first feeding mechanism 2 and the second feeding mechanism 4 synchronously transport the pearl cotton sheet through the gantry-shaped translation bracket 331. After the cross-section detection mechanism 34 detects that the cross-section has moved to the welding area, the front shaping pressure plate 321 descends and presses down on the rear end of the front material block. The first feeding mechanism 2 decelerates or pauses, so that the cross-section is separated into a gap that allows the heating plate 31 to be inserted. The rear shaping pressure plate 322 descends and presses down on the front end of the rear material block. The heating plate 31 is inserted into the gap between the two material blocks to heat the rear end of the front material block and the front end of the rear material block simultaneously. After both end faces are melted... The heating plate 31 rises away from the connection position, the rear shaping plate 322 rises to release the front end of the rear material block, the first feeding mechanism 2 accelerates forward, so that the front end of the rear material block quickly abuts the rear end of the front material block for welding, and at the same time the rear shaping plate 322 descends to press the front end of the rear material block until the welded part cools and sets. The front shaping plate 321 and the rear shaping plate 322 rise away from the welding position at the same time. During the welding process, the welding frame 33 moves forward synchronously with the second feeding mechanism 4 under the drive of the translation drive motor 330. After the welding is completed, the welding frame 33 moves backward under the drive of the translation drive motor 330 and returns to the welding standby position.
