Description

Technical Field

[0001] This invention relates to the field of hose cutting technology, specifically to a fully automatic hose cutting machine that prevents the cutter from clamping. Background Technology

[0002] In patent application CN220362667U, a workbench is included. A vertical plate is mounted on top of the workbench, and a lifting mechanism is mounted on the vertical plate. A cutting mechanism is connected to the lifting mechanism. A guide groove is formed on the top of the workbench, and multiple conveying mechanisms are arranged within the guide groove. Four guide mechanisms are symmetrically arranged on the top of the workbench, and the cutting mechanism is located between the four guide mechanisms. The advantages are: the hose is placed on top of multiple conveying wheels, an electric push rod moves the guide frame, and the guide frame drives the guide wheels. The guide wheels on both sides of the hose can limit the hose's movement, preventing it from deviating during conveying, and it can accommodate hoses of different sizes.

[0003] In existing technologies, including the aforementioned patents, optimizations and improvements are mainly made to address shortcomings such as the accuracy of cutting and conveying, and reducing deformation at the cut of the hose. However, in actual processing, when cutting hoses, the blade often gets stuck because the cut hose does not move away from the blade in time. This not only requires workers to stop the machine for handling, but also makes it easy for the blade to cut the workers' hands. This not only delays the production progress, but also increases the risk to the workers' hands. Furthermore, it cannot be adapted to hoses of different hardness to further prevent the blade from getting stuck. Summary of the Invention

[0004] The problem this invention aims to solve is that it is difficult to prevent the cutter from jamming when cutting rubber hoses that are hard and have thick walls.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a fully automatic hose cutting machine with anti-cutting blade jamming, including a feeding trough and a hydraulic assembly located between two feeding troughs. The feeding troughs are symmetrically arranged along the center line of the hydraulic assembly. The hydraulic assembly consists of a hydraulic rod, a mounting frame, and related control elements. A fixing component of a protective assembly is fixedly installed at the lower end of the hydraulic rod of the hydraulic assembly. The protective assembly has two parts: one part is the fixing component installed at the lower end of the hydraulic rod, and the other part is the pushing component located below the fixing component. The protective assembly is used to assist in hose positioning and cutting and to prevent blade jamming. A blade from a cutting assembly is arranged between the pushing components of the protective assembly. A cleaning component is arranged inside the protective assembly. The cleaning component is used to clean the blade and discharge material and to assist the operation of the protective assembly.

[0006] Preferably, the protective assembly includes a mounting plate installed at the lower end of the hydraulic rod. The mounting plate is cross-shaped, and a limit rod is fixedly installed in the middle of the interior of the mounting plate. There are four limit rods in total, which are symmetrically arranged along the center line of the mounting plate. Springs are provided around the limit rods, and a locking block is slidably provided below the mounting plate.

[0007] Preferably, the upper end of the locking block is located inside the mounting plate and is slidably connected to the limiting rod. The two ends of the spring are fixedly connected to the mounting plate and the locking block respectively. A guide block is provided below the locking block, and the upper end of the guide block is opened at an angle. The mounting plate, the limiting rod, the spring, the locking block and the guide block are the pushing component in the protective assembly.

[0008] Preferably, the protective assembly further includes a housing located directly below the mounting plate. The upper end of the housing is fixedly connected to the guide block by bolts. A protective cover is provided inside the housing. Two protective covers are symmetrically arranged along the center line of the housing. A fixing block is fixedly provided on the outer side of each protective cover. The fixing blocks are symmetrically arranged along the center line of the protective cover.

[0009] Preferably, limit blocks are provided on both sides of the fixing block, the number of limit blocks is the same as the number of fixing blocks, the limit blocks are fixedly connected to the outer shell, the fixing block is connected to the limit blocks by bolts, and the distance between the sliding groove in the middle of the limit block and the protective cover gradually decreases from bottom to top.

[0010] Preferably, the protective covers are connected by rubber pads, and two rubber pads are provided. The rubber pads only serve to block the wind and can be stretched as the protective covers move. The upper end of the protective cover has multiple air vents, all of which are located on the inclined surface of the protective cover. The outer shell, protective cover, fixing block, limiting block, rubber pads and air vents in the protective assembly are material pushing components.

[0011] Preferably, the cutting assembly includes a blade located between protective covers, a motor and its mounting bracket are provided on one side of the blade, the motor and its mounting bracket are located outside the housing, and the motor shaft in the motor and its mounting bracket is fixedly connected to the blade.

[0012] Preferably, the mounting bracket of the motor and its mounting frame is located below the feeding trough. The motor and its mounting frame are used to control the up and down movement of the protective components and the blade. The blade and the motor shaft are not directly connected to the protective cover.

[0013] Preferably, the cleaning component includes an impeller, which is fixedly connected to the motor shaft in the motor and its mounting bracket. Two impellers are symmetrically arranged along the center line of the blade. The impellers rotate synchronously with the blade, and the outer edge of the impeller is rotatably connected to the protective cover.

[0014] Preferably, a scraper is fixedly installed below the impeller inside the protective cover. There are four sets of scrapers. The side of the scraper closest to the blade contacts and slides with the blade. The other side of the scraper has a cavity through the protective cover. The cavity is only connected to the scraper and the air outlet.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) Under the protection of the protective components, the tube can be cut without significantly changing the shape of the tube at the cutting point. Under the same displacement, the contact area between the tube and the blade is reduced, thereby reducing the probability of jamming. Secondly, by stretching the tube to both sides, the tube can rebound after cutting using its own elasticity, thereby further reducing the contact area between the blade and the tube during cutting, and further reducing the probability of jamming. Moreover, the protective cover in the protective components can also reduce jamming when the device cuts tubes of different materials. It is worth mentioning that the blade adopts a recessed design and the protective cover can also prevent workers from accidentally touching the blade, thereby improving the safety of the device. Furthermore, the downward cutting can facilitate the collection of debris and reduce the probability of splashing. (2) By setting up the cleaning component, the impeller can first provide air to the protective component, which can scrape off the debris adhering to the edge of the blade. This not only allows for the centralized collection of debris, but also reduces the impact of debris on the blade. The scraper can also be used to polish the edge of the blade, thereby extending the service life of the blade to a certain extent. Moreover, this only happens for a short period of time after the blade starts to rotate and stops rotating, so it will not over-polish the blade. It is worth mentioning that the air generated by the impeller can also guide the scraped debris, forcing it to move to a designated location. This ensures a clean work environment and reduces the workload during cleaning. Attached Figure Description

[0020] like Figures 1 to 9As shown, the present invention provides a fully automatic hose cutting machine with anti-cutting blade jamming, including a feeding trough 1 and a hydraulic assembly 2 located between two feeding troughs 1. The feeding troughs 1 are symmetrically arranged along the center line of the hydraulic assembly 2. The hydraulic assembly 2 consists of a hydraulic rod, a mounting frame, and related control elements. A fixing component in a protective assembly 3 is fixedly installed at the lower end of the hydraulic rod of the hydraulic assembly 2. The protective assembly 3 has two parts: one part is the fixing component installed at the lower end of the hydraulic rod, and the other part is the pushing component located below the fixing component. The protective assembly 3 is used to assist hose positioning and cutting and to prevent blade jamming. A blade 402 in a cutting assembly 4 is arranged between the pushing components of the protective assembly 3. A cleaning component 5 is arranged inside the protective assembly 3. The cleaning component 5 is used to clean the blade 402 and discharge material and to assist the operation of the protective assembly 3.

[0021] The protective component 3 includes a mounting plate 301 installed at the lower end of the hydraulic rod. The mounting plate 301 is cross-shaped. A limit rod 302 is fixedly installed in the middle of the interior of the mounting plate 301. There are four limit rods 302 in total. The limit rods 302 are symmetrically arranged along the center line of the mounting plate 301. Springs 303 are arranged around the limit rods 302. A locking block 304 is slidably arranged below the mounting plate 301.

[0022] The upper end of the locking block 304 is located inside the mounting plate 301 and is slidably connected to the limiting rod 302. The two ends of the spring 303 are fixedly connected to the mounting plate 301 and the locking block 304 respectively. A guide block 305 is provided below the locking block 304. The upper end of the guide block 305 is opened with an incline. The mounting plate 301, the limiting rod 302, the spring 303, the locking block 304 and the guide block 305 are the pushing components in the protective assembly 3.

[0023] The protective component 3 also includes a housing 306, which is located directly below the mounting plate 301. The upper end of the housing 306 is fixedly connected to the guide block 305 by bolts. A protective cover 307 is provided inside the housing 306. Two protective covers 307 are symmetrically arranged along the center line of the housing 306. A fixing block 308 is fixedly provided on the outer side of each protective cover 307. The fixing blocks 308 are symmetrically arranged along the center line of the protective cover 307.

[0024] Limiting blocks 309 are provided on both sides of the fixing block 308. The number of limiting blocks 309 is the same as the number of fixing blocks 308. The limiting blocks 309 are fixedly connected to the outer shell 306. The fixing block 308 is connected to the limiting blocks 309 by bolts. The distance between the sliding groove in the middle of the limiting block 309 and the protective cover 307 gradually decreases from bottom to top.

[0025] The protective covers 307 are connected by rubber pads 310. There are two rubber pads 310. The rubber pads 310 only serve to block the wind. The rubber pads 310 can be stretched as the protective covers 307 move. The upper end of the protective cover 307 has multiple air vents 311. The air vents 311 are all opened on the inclined surface of the protective cover 307. The outer shell 306, protective cover 307, fixing block 308, limiting block 309, rubber pads 310 and air vents 311 in the protective assembly 3 are material pushing components.

[0026] The cutting assembly 4 includes a blade 402 located between protective covers 307. A motor and its mounting bracket 401 are provided on one side of the blade 402. The motor and its mounting bracket 401 are located outside the housing 306. The motor shaft in the motor and its mounting bracket 401 is fixedly connected to the blade 402.

[0027] The mounting bracket of the motor and its mounting bracket 401 is located below the feeding trough 1. The motor and its mounting bracket 401 are used to control the up and down movement of the protective component 3 and the blade 402. The blade 402 and the motor shaft are not directly connected to the protective cover 307.

[0028] The cleaning component 5 includes an impeller 501, which is fixedly connected to the motor shaft in the motor and its mounting bracket 401. Two impellers 501 are symmetrically arranged along the center line of the blade 402. The impellers 501 and the blade 402 rotate synchronously. The outer edge of the impeller 501 is rotatably connected to the protective cover 307.

[0029] Below the impeller 501, inside the protective cover 307, there is a fixed scraper 502. There are four sets of scraper 502. The side of the scraper 502 closest to the blade 402 contacts and slides with the blade 402. The other side of the scraper 502 has a cavity 503 through the protective cover 307. The cavity 503 is only connected to the scraper 502 and the air outlet.

[0030] The working principle and usage process of this invention are as follows: When the hose is transported by the feeding trough 1 and the cutting position moves to below the hydraulic component 2, the hydraulic rod pushes the mounting plate 301 downward. At this time, the clamping block 304 is in the default position near the middle. As it moves downward, the hose is gradually fixed below the clamping block 304. As the clamping block 304 continues to move downward, it can not only drive the cutting point of the hose to continue to move downward, but also move outward under the action of the guide block 305. At this time, the hose can be pulled to both sides. When the mounting plate 301 moves to the appropriate position, the cutting component 4 is activated, causing the blade 402 to move upward and cut the hose. During the cutting process, there are two situations: When the hose has good resilience, the cut hose can retract to both sides under the pulling force generated by the clamping block 304, allowing the cut hose to leave the range of the blade 402 in time, thereby reducing the contact area between the hose and the blade 402 to a certain extent. When the hose has poor resilience, as the blade 402 moves upward, the protective cover 307 can also move upward. During the upward movement, the protective cover 307 can gradually move diagonally upward under the guidance of the limiting block 309. Based on this, the inclined surface at the upper end of the protective cover 307 can be used to push the hose to both sides, forcibly forcing the hose away from the blade 402. It should be noted that the hoses on both sides of the cut will not move downwards too far due to their own weight and the friction with the feed trough 1, thus ensuring that the hoses at the cut can be stretched normally. When the blade 402 rotates, the impellers 501 on both sides rotate synchronously to generate centrifugal air. The airflow is discharged from the air outlet 311, the gap between the blade 402 and the protective cover 307, and the air outlet below the protective cover 307. This airflow blows the debris scraped off the blade 402 by the scraper 502 towards the area below the protective cover 307 for centralized processing. At the same time, under the guidance of the scraper 502, some debris is blown towards the cavity 503, which is connected to the air outlet of the protective cover 307. Utilizing Bernoulli's principle, the airflow at the air outlet draws air out of the cavity 503, and combined with the airflow guided by the scraper 502, effectively reduces the probability of debris remaining in the cavity 503. It should be noted that scraping is only performed when the protective cover (307) is moved to its lowest point.
