A quantitative feeding device for processing heat-shrinkable materials

Abstract

This utility model relates to the field of heat-shrinkable material processing, and more particularly to a quantitative feeding device for heat-shrinkable material processing. This utility model provides a quantitative feeding device for heat-shrinkable material processing that can intermittently clear the discharge port of the storage bin while scraping material, preventing blockage of the storage bin from affecting the feeding process. A quantitative feeding device for heat-shrinkable material processing includes a support frame, a storage bin, and a feed cover. The storage bin is connected to the upper part of the support frame, and the feed cover is snapped onto the upper part of the storage bin. In this utility model, the rotation of the scraper causes the extrusion block to rotate. When the extrusion block rotates and contacts the extrusion frame, the extrusion frame squeezes the extrusion block, causing it to move downwards. The compression spring contracts, causing the unblocking rod to move downwards to clear the blockage, thus achieving intermittent clearing of the discharge port of the storage bin while scraping material, preventing blockage of the storage bin from affecting the feeding effect.

Description

Technical Field

[0001] This utility model relates to the field of heat shrinkable material processing, and in particular to a quantitative feeding device for heat shrinkable material processing. Background Technology

[0002] In the processing and production of heat-shrinkable materials, the quantitative feeding device is one of the key pieces of equipment to ensure production continuity and product quality stability. Traditional feeding devices usually use a simple combination of a storage bin and a discharge mechanism. The heat-shrinkable material raw material is discharged from the storage bin by gravity and then transported to the subsequent processing stage by a conveying screw. However, in practical applications, due to the physical characteristics of heat-shrinkable materials, the discharge port of the storage bin is prone to blockage during long-term operation. Blockage of the discharge port will interrupt the feeding process, reduce production efficiency, and increase maintenance costs.

[0003] Therefore, it is necessary to design a quantitative feeding device for heat shrinkable material processing that can intermittently clear the discharge port of the storage bucket while scraping the material, so as to avoid the storage bucket being blocked and affecting the feeding. Utility Model Content

[0004] To overcome the shortcomings of existing quantitative feeding devices for heat-shrinkable materials, such as the physical properties of heat-shrinkable materials easily causing blockages at the discharge port of the storage bin during long-term operation, which interrupts the feeding process, reduces production efficiency, and increases maintenance costs, this utility model provides a quantitative feeding device for heat-shrinkable material processing that can intermittently unclog the discharge port of the storage bin while scraping the material, thus avoiding blockages affecting the feeding process.

[0005] The technical solution is as follows: A quantitative feeding device for heat shrinkable material processing includes a support frame, a storage bin, a feed cover, a connecting frame, a motor, a conveying cylinder, a conveying screw, a scraping component, and a clearing component. The storage bin is connected to the upper part of the support frame, and the feed cover is snapped onto the upper part of the storage bin. The connecting frame is connected to the lower part of the support frame, and the motor is connected to the upper left part of the connecting frame. The conveying cylinder is connected to the storage bin, and the conveying screw is rotatably connected inside the conveying cylinder. The output shaft of the motor is connected to the conveying screw. The feed cover is equipped with a scraping component that can scrape the inner wall of the storage bin while feeding material, and the scraping component is equipped with a clearing component that can clear the discharge port of the storage bin while scraping material.

[0006] As a further preferred option, a feed pipe is provided on the upper rear side of the feed cover.

[0007] As a further preferred option, an air inlet frame is also included, with the air inlet frame connected to the upper right side of the feed cylinder.

[0008] As a further preferred embodiment, the scraping assembly includes a transmission module, a rotating shaft, a bevel gear, and a scraping frame. The rotating shaft is rotatably connected to the upper left of the feed cover, and a transmission module is provided between the rotating shaft and the feed cylinder. The scraping frame is rotatably connected to the middle of the feed cover, and a bevel gear is connected to the upper part of the scraping frame. A bevel gear is also connected to the right side of the rotating shaft, and the bevel gears mesh with each other.

[0009] As a further preferred embodiment, the transmission module includes a pulley and a flat belt, with a pulley connected to the left side of the rotating shaft and a pulley also connected to the left side of the conveying cylinder, and a flat belt wound between the pulleys.

[0010] As a further preferred embodiment, a dredging assembly is also included, which includes a squeezing frame, a dredging rod, a squeezing block, and a telescopic spring. The squeezing frame is connected to the upper right side of the feed cover, and the dredging rod is slidably connected to the middle of the scraper. The squeezing block is connected to the upper side of the dredging rod, and a telescopic spring is connected between the dredging rod and the scraper.

[0011] The present invention has the following advantages: 1. When the scraper rotates, the extrusion block will rotate. When the extrusion block rotates and contacts the extrusion frame, the extrusion frame squeezes the extrusion block, causing the extrusion block to move downward. The telescopic spring is squeezed and contracted, causing the unblocking rod to move downward to unblock. This achieves the goal of intermittently unblocking the discharge port of the storage bucket while scraping the material, thus avoiding blockage of the storage bucket and affecting the feeding effect.

[0012] 2. This utility model allows for the connection of an air inlet frame to an external air supply pipe during the feeding process, enabling air to be blown through the air inlet frame onto the conveying screw, thereby blowing off the heat-shrinkable material adhering to the conveying screw during the feeding process. This avoids blockage of the conveying channel due to material accumulation and improves the accuracy of the feeding quantity. Attached Figure Description

[0020] A quantitative feeding device for processing heat-shrinkable materials, such as Figures 1-4 As shown, the assembly includes a support frame 1, a storage bin 2, a feed cover 3, a connecting frame 4, a motor 5, a conveying cylinder 6, a conveying screw 7, an air intake frame 8, a scraping assembly, and a clearing assembly. The storage bin 2 is connected to the upper part of the support frame 1, and the feed cover 3 is snapped onto the upper part of the storage bin 2. A feed pipe is provided on the upper rear side of the feed cover 3 for easy feeding. The connecting frame 4 is connected to the lower part of the support frame 1, and the motor 5 is connected to the upper left side of the connecting frame 4. The conveying cylinder 6 is connected to the connecting frame 4 and is connected to the storage bin 2. The conveying screw 7 is rotatably connected inside the conveying cylinder 6, and the output shaft of the motor 5 is connected to the conveying screw 7. The air intake frame 8 is connected to the upper right side of the conveying cylinder 6, and a scraping assembly is provided on the feed cover 3. A clearing assembly is provided on the scraping assembly.

[0021] like Figure 2 and Figure 4 As shown, the scraping assembly includes a transmission module 9, a rotating shaft 10, a bevel gear 11, and a scraper frame 12. The rotating shaft 10 is rotatably connected to the upper left of the feed cover 3. The transmission module 9 is provided between the rotating shaft 10 and the conveying cylinder 6. The transmission module 9 includes a pulley and a flat belt. The left side of the rotating shaft 10 is connected to a pulley, and the left side of the conveying cylinder 6 is also connected to a pulley. A flat belt is wound between the pulleys. The scraper frame 12 is rotatably connected to the middle of the feed cover 3. The upper part of the scraper frame 12 is connected to a bevel gear 11, and the right side of the rotating shaft 10 is also connected to a bevel gear 11. The bevel gears 11 mesh with each other.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it also includes a dredging assembly, which includes a squeezing frame 13, a dredging rod 14, a squeezing block 15, and a telescopic spring 16. The squeezing frame 13 is connected to the upper right side of the feed cover 3, and the dredging rod 14 is slidably connected to the middle of the scraper frame 12. The squeezing block 15 is connected to the upper side of the dredging rod 14, and the telescopic spring 16 is connected between the dredging rod 14 and the scraper frame 12.

[0023] When using this device, first place the support frame 1 in the quantitative feeding area for heat-shrinkable materials, then discharge the heat-shrinkable material into the storage bin 2 through the feeding pipe on the feeding cover 3. Then start the motor 5 to drive the conveying screw 7 to rotate, so that the heat-shrinkable material in the storage bin 2 enters the conveying cylinder 6. The heat-shrinkable material is quantitatively conveyed by the number of rotations of the conveying screw 7, so that the heat-shrinkable material is discharged from the lower right of the conveying cylinder 6 for feeding. At the same time, the rotation of the conveying screw 7 will drive the pulley to rotate, so that the flat belt will rotate. Through the pulley on the transmission module 9 and the flat belt, the rotating shaft 10 will rotate, so that the bevel gear 11 will rotate. The bevel gear 11 meshes with each other, driving the scraper 12 to rotate, so that the material adhering to the inner wall of the storage bin 2 will be scraped off. When the scraper 12 rotates, it will drive the extrusion block 15 to rotate. When the pressing block 15 rotates and contacts the extrusion frame 13, the extrusion frame 13 squeezes the pressing block 15, causing the pressing block 15 to move downward. The telescopic spring 16 is compressed and contracts, causing the unblocking rod 14 to move downward to unblock. When the pressing block 15 no longer contacts the extrusion frame 13, the telescopic spring 16 returns to its original state, causing the unblocking rod 14 to move upward to reset. This allows for intermittent unblocking of the discharge port of the storage bucket 2 while scraping the material, preventing blockage of the storage bucket 2 from affecting the feeding process. During the feeding process, an air supply pipe can be connected to the air inlet frame 8 to blow air through the air inlet frame 8 onto the conveying screw 7, blowing off the heat-shrinkable material adhering to the conveying screw 7. This prevents blockage of the conveying channel caused by material accumulation and improves the accuracy of the feeding amount.
