Description

Technical Field

[0001] This invention relates to the field of pearl cotton processing technology, specifically to a sample making machine for pearl cotton production. Background Technology

[0002] Pearl cotton sampling machines are specialized CNC equipment used by packaging factories to make inner lining samples and small batches of irregularly shaped pearl cotton. They do not require cutting molds; the drawings are imported into the computer and cut directly. They are specifically designed to solve the needs of rapid sampling of new products and repeated trial production of modified designs. The mainstream types are vibrating knife sampling machines, laser sampling machines, and die-cutting and stamping sampling machines.

[0003] Currently, existing EPE foam sampling machines still have many inconveniences in actual production: On the one hand, the feeding process of most sampling machines still requires manual handling of stacked EPE foam sheets to the cutting station, which not only increases the labor intensity of operators but also results in low efficiency of manual handling and feeding, making it difficult to match the pace of automated cutting and processing; on the other hand, after manually placing the EPE foam, it is necessary to manually adjust its position for positioning and fixing, which can easily affect the cutting accuracy due to positioning deviation, and the positioning process is time-consuming, further reducing the overall efficiency of sampling and processing. In addition, the waste and finished products generated after cutting often need to be manually unloaded and sorted, making it impossible to achieve continuous processing and difficult to meet the production needs of rapid sampling of small batches of EPE foam. Summary of the Invention

[0007] It also includes a push block fixedly connected to the movable seat, a sliding groove provided on the slide, the movable seat slidably connected to the sliding groove, and multiple support frames fixedly connected to the bottom of the slide.

[0008] It also includes a connecting frame fixedly connected to the movable base, and the telescopic end of the first electric push rod is fixedly connected to the connecting frame.

[0009] It also includes multiple storage racks fixedly connected to the slide, the multiple storage racks forming a square, the storage racks having positioning grooves, the pearl cotton being placed in the positioning grooves on the multiple storage racks, and two of the storage racks having discharge grooves at their bottoms.

[0010] It also includes that the bottom of the sample making machine body is fixedly connected to multiple limiting frames, and the limiting frames and the synchronization frame are movably connected.

[0011] It also includes a square opening on the surface of the sample making machine body, a feeding plate rotatably connected inside the square opening, a feeding mechanism at the bottom of the sample making machine body, the feeding mechanism including a second electric push rod, a rotating seat fixedly connected to the feeding plate, and the telescopic end of the second electric push rod rotatably connected to the rotating seat.

[0012] The material feeding mechanism also includes a fixing plate, which is fixedly connected to the bottom of the sample making machine body. The fixing plate has an arc-shaped groove, and a fixing rod is fixedly connected to the material feeding plate. The fixing rod extends into the arc-shaped groove and is slidably connected to the arc-shaped groove. A mounting base is fixedly connected between the two fixing plates, and the second electric push rod is mounted on the mounting base.

[0013] It also includes a guide plate at the bottom of the sample making machine body, a fixed frame fixedly connected to the sample making machine body, the fixed frame and the guide plate being fixedly connected, and a conveyor belt being provided below the guide plate.

[0014] It also includes that the surface of the sample making machine body is provided with multiple air holes, the bottom of the sample making machine body is provided with a sealed chamber communicating with the air holes, a negative pressure pump is installed below the sample making machine body, and an air pipe is connected between the air intake end of the negative pressure pump and the sealed chamber.

[0015] It also includes an electric slide rail mounted on the surface of the sample making machine body, a movable frame slidably connected to the electric slide rail, an electric slide rail mounted on the movable frame, a slider slidably on the movable frame, two L-shaped seats fixedly connected to the slider, a third electric push rod and a fourth electric push rod respectively mounted on the two L-shaped seats, a vibrating knife fixedly connected to the telescopic end of the third electric push rod, and a fixing block fixedly connected to the telescopic end of the fourth electric push rod.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art:

[0017] 1. This invention, through the cooperation of the feeding mechanism and the limiting mechanism, can simultaneously drive the limiting mechanism to complete the position correction and limiting of the pearl cotton during the automatic feeding process. It eliminates the need for an additional independent power component to drive the limiting mechanism, simplifying the overall structure of the device and reducing manufacturing costs and operating energy consumption. Simultaneously, the automatic feeding and positioning processes are completed concurrently, reducing the workload of manual alignment adjustments, avoiding manual positioning errors, and effectively improving the accuracy and processing efficiency of pearl cotton sampling and cutting, thus meeting the needs of small-batch, multi-specification pearl cotton sampling production.

[0018] 2. This invention, through its feeding mechanism, can quickly deliver the finished product from the sample-making machine body after the pearl cotton is cut, eliminating the need for manual removal of the cut samples. This further enhances the automation level of processing and reduces the safety hazards and operation time associated with manual feeding. During the feeding process, the arc-shaped groove limits the rotation trajectory of the fixing rod and the feeding plate, ensuring a stable and smooth start and stop process for the feeding plate. This prevents the feeding plate from tilting and jamming, which could cause the finished product to get stuck at the discharge position, ensuring the stable operation of the feeding process. After feeding, the finished pearl cotton can slide directly onto the conveyor belt through the guide plate, eliminating the need for manual transfer and further improving the continuous operation capability of sample-making production.

[0019] 3. This invention, through the cooperation of a negative pressure pump, air pipe, sealing chamber, and air vents, can stably adsorb and fix the pearl cotton onto the processing table of the sample making machine body during the pearl cotton cutting process using negative pressure. Combined with a limiting mechanism, this achieves double positioning and fixation, effectively preventing the problem of the soft pearl cotton easily shifting during cutting, ensuring the accuracy of the cutting contour, and avoiding sample scrap due to cutting deviation. At the same time, the negative pressure adsorption and fixation method will not create indentations on the pearl cotton surface, will not damage the appearance and structure of the finished pearl cotton, and ensures that the quality of the sample meets the testing requirements.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to embodiments.

[0032] Example 1:

[0033] Please see Figures 1-8This invention provides a technical solution: a sample-making machine for EPE foam production, comprising a sample-making machine body 1, a slide block 2 fixedly connected to the sample-making machine body 1, a feeding mechanism 3 for automatically feeding EPE foam on the slide block 2, and a limiting mechanism 5 for limiting the EPE foam on the sample-making machine body 1; the feeding mechanism 3 drives the limiting mechanism 5 to move synchronously during startup, thereby achieving automatic feeding while limiting the EPE foam, the feeding mechanism 3 including a first electric push rod 32, the first... An electric push rod 32 has a telescopic end fixedly connected to a movable seat 31, which is slidably connected to a slide block 2. The limiting mechanism 5 includes a first baffle 52 and a second baffle 53, both of which are slidably connected to the surface of the sample making machine body 1. A synchronization frame 54 is fixedly connected to the first baffle 52 and the second baffle 53. A first arc-shaped seat 51 is fixedly connected to the second baffle 53. A second arc-shaped seat 55 that cooperates with the first arc-shaped seat 51 is fixedly connected to the movable seat 31.

[0034] In practice: the combination of the feeding mechanism 3 and the limiting mechanism 5 enables automatic feeding and alignment of the pearl cotton, thereby avoiding positional deviation during manual feeding, ensuring the accuracy of sample cutting, and eliminating the need for repeated manual position adjustments, thus effectively improving the efficiency of sample processing.

[0035] In use, stacked pearl cotton is placed in advance in the positioning slots 401 of multiple storage racks 4, with the bottom layer of pearl cotton aligned with the discharge slot 402. The first electric push rod 32 is activated, its telescopic end extending to push the connecting frame 33 and the moving seat 31 along the slide 201 towards the processing area of ​​the sample making machine body 1. During the movement of the moving seat 31, the push block 34 pushes the pearl cotton at the discharge slot 402 towards the processing area, completing the automatic feeding. During this process, the second arc-shaped seat 55 on the moving seat 31 moves synchronously with the moving seat 31. When the second arc-shaped seat 55 contacts the first arc-shaped seat 51, it pushes the first arc-shaped seat 51 and the second baffle 53 to move. The second baffle 53, through the synchronous frame 54, drives the first baffle 52 to move synchronously towards the pearl cotton, allowing the first baffle 52 and the second baffle 53 to push and calibrate the pearl cotton from both sides, ultimately limiting the pearl cotton to the preset position in the processing area, completing the feeding and positioning process.

[0036] The feeding mechanism 3 can send unsampled pearl cotton into the sampling station, and at the same time, the new pearl cotton pushes the sampled pearl cotton out of the sampling station, thus automatically completing the feeding and unloading process.

[0037] Please see Figures 2-3The present invention provides a technical solution: a push block 34 is fixedly connected to the movable seat 31, a sliding groove 201 is provided on the sliding seat 2, the movable seat 31 is slidably connected to the sliding groove 201, and a plurality of support frames 202 are fixedly connected to the bottom of the sliding seat 2.

[0038] In practice: the pusher block 34 is used to move the pearl cotton, thereby pushing the pearl cotton to the sampling station.

[0039] Please see Figures 2-3 The present invention provides a technical solution: a connecting frame 33 is fixedly connected to the movable seat 31, and the telescopic end of the first electric push rod 32 is fixedly connected to the connecting frame 33.

[0040] In practice: the connecting frame 33 and the movable seat 31 have multiple connection points, thereby improving the stability of the connection.

[0041] Example 2:

[0042] Please see Figure 3 Based on implementation one, the present invention also provides a technical solution: multiple storage racks 4 are fixedly connected to the slide 2, the multiple storage racks 4 form a square, the storage racks 4 are provided with positioning grooves 401, the pearl cotton is placed in the positioning grooves 401 on the multiple storage racks 4, and the bottom of two of the storage racks 4 are provided with discharge grooves 402.

[0043] In practice: multiple storage racks 4 are set up to store pearl cotton, and the bottom pearl cotton is aligned with the discharge trough 402, so as to achieve accurate discharge of pearl cotton.

[0044] Please see Figures 1-2 The present invention provides a technical solution: a plurality of limiting frames 22 are fixedly connected to the bottom of the sample making machine body 1, and the limiting frames 22 and the synchronization frame 54 are movably connected.

[0045] In practice: the limiting frame 22 is used to support the synchronization frame 54 to prevent the first baffle 52 and the second baffle 53 from falling off.

[0046] Please see Figures 4-8 The present invention provides a technical solution: a square opening is provided on the surface of the sample making machine body 1, and a feeding plate 7 is rotatably connected in the square opening. A feeding mechanism 6 is provided at the bottom of the sample making machine body 1. The feeding mechanism 6 includes a second electric push rod 61. A rotating seat 62 is fixedly connected to the feeding plate 7. The telescopic end of the second electric push rod 61 is rotatably connected to the rotating seat 62.

[0047] In practice: the feeding mechanism 6 and the feeding plate 7 are used to clean up the waste material after sampling, remove the waste material after sampling from the sampling machine body 1, and drive the feeding plate 7 to rotate through the feeding mechanism 6, thereby guiding the pearl cotton waste material on the feeding plate 7 to the outside of the sampling machine body 1.

[0048] Example 3:

[0049] Please see Figure 5 Based on Embodiment 1, the present invention also provides a technical solution: the feeding mechanism 6 further includes a fixing plate 63, the fixing plate 63 is fixedly connected to the bottom of the sample making machine body 1, the fixing plate 63 is provided with an arc-shaped groove 65, the feeding plate 7 is fixedly connected with a fixing rod 66, the fixing rod 66 extends into the arc-shaped groove 65 and is slidably connected with the arc-shaped groove 65, and a mounting base 64 is fixedly connected between the two fixing plates 63, and the second electric push rod 61 is mounted on the mounting base 64.

[0050] In specific implementation: The working process of the feeding mechanism 6 is as follows: After the cutting and sampling are completed, the second electric push rod 61 is activated. The telescopic end of the second electric push rod 61 retracts, pulling the rotating seat 62 and the feeding plate 7 downward as a whole. During the deflection of the feeding plate 7, the fixing rod 66 at its end slides along the arc groove 65 on the fixing plate 63, limiting the rotation range of the feeding plate 7 and ensuring that the feeding plate 7 rotates stably without deviation. Finally, the feeding plate 7 is tilted, and the finished pearl cotton or waste material after sampling can automatically slide out of the processing area along the tilted feeding plate 7 without manual cleaning. When the next sampling operation is required, the telescopic end of the second electric push rod 61 extends, pushing the feeding plate 7 back to a position flush with the surface of the sampling machine body 1, so that it can normally receive new pearl cotton to be processed. The operation is convenient and smooth.

[0051] Please see Figure 4 , Figure 6 The present invention provides a technical solution: a guide plate 8 is provided at the bottom of the sample making machine body 1, a fixed frame 9 is fixedly connected to the sample making machine body 1, the fixed frame 9 and the guide plate 8 are fixedly connected, and a conveyor belt 17 is provided below the guide plate 8.

[0052] In practice: The fixed frame 9 stably supports and fixes the guide plate 8 to the bottom of the sample making machine body 1. The finished pearl cotton or waste material that slides out of the feeding plate 7 will fall on the guide plate 8. After being guided by the guide plate 8, it will fall stably into the conveyor belt 17 below. The conveyor belt 17 will transport the material to the designated collection position, realizing the automated conveying of the entire sample making process and reducing the manual transfer links.

[0053] Example 4:

[0054] Please see Figure 5Based on Embodiment 1, the present invention also provides a technical solution: the surface of the sample making machine body 1 is provided with a plurality of air holes 21, the bottom of the sample making machine body 1 is provided with a sealed chamber 20 communicating with the air holes 21, a negative pressure pump 18 is installed below the sample making machine body 1, and an air pipe 19 is connected between the suction end of the negative pressure pump 18 and the sealed chamber 20.

[0055] In practice: when the pearl cotton moves to the processing area on the surface of the sample making machine body 1, the negative pressure pump 18 is started. The negative pressure pump 18 draws air from the sealed chamber 20 through the air pipe 19, so that the sealed chamber 20 forms a negative pressure. Thus, the pearl cotton is firmly adsorbed and fixed on the surface of the sample making machine body 1 through multiple air holes 21, which prevents the pearl cotton from shifting during the cutting process, ensures the cutting accuracy, and ensures the flatness of the pearl cotton surface, thereby avoiding the situation of incomplete cutting during the cutting process, and thus preventing waste material from sticking to the pearl cotton after cutting.

[0056] After the cutting and prototyping are completed, the negative pressure pump 18 is turned off to release the adsorption and fixation of the pearl cotton. Then, the second electric push rod 61 is started, and its telescopic end retracts to drive the rotating seat 62 and the feeding plate 7 to move down. The feeding plate 7 rotates along the arc groove 65 with the fixed rod 66 as the axis, so that the feeding plate 7 rotates and tilts. The processed pearl cotton slides down the tilted feeding plate 7 to the guide plate 8, and then slides down the guide plate 8 to the conveyor belt 17. The conveyor belt 17 transports the processed pearl cotton to the next process, completing the automatic feeding, further reducing the intensity of manual labor and improving the overall processing efficiency.

[0057] Please see Figures 7-8 The present invention provides a technical solution: an electric slide rail is installed on the surface of the sample making machine body 1, a movable frame 10 is slidably connected to the electric slide rail, an electric slide rail is installed on the movable frame 10, a slider 11 is slidably connected to the movable frame 10, two L-shaped seats 12 are fixedly connected to the slider 11, a third electric push rod 13 and a fourth electric push rod 15 are respectively installed on the two L-shaped seats 12, a vibrating knife 14 is fixedly connected to the telescopic end of the third electric push rod 13, and a fixing block 16 is fixedly connected to the telescopic end of the fourth electric push rod 15.

[0058] In specific implementation: After fixing, the moving frame 10 is driven by the electric slide rail to move laterally on the surface of the sample making machine body 1, and at the same time, the slider 11 is driven to move longitudinally on the moving frame 10 to adjust the position of the vibrating knife 14 and the fixed block 16. After the position is adjusted, the third electric push rod 13 is started, and its telescopic end extends to drive the vibrating knife 14 to move down to cut and sample the pearl cotton. When other processing steps such as pressing the pearl cotton are required, the fourth electric push rod 15 can drive the fixed block 16 to move down to complete the corresponding processing. The fixed block 16 can also push the waste material adhering to the cut pearl cotton out of the feeding area when cleaning the waste material, so as to ensure that the waste material can be smoothly discharged with the finished pearl cotton and avoid the waste material remaining in the processing area to affect the subsequent sample making operation.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
