Description

Technical Field

[0001] The present invention relates to the technical field of hose cutting, and specifically to a fully automatic hose cutting machine that prevents the cutting edge from jamming the knife. Background Art

[0002] In the patent application with the application publication number CN220362667U, it includes a workbench. A vertical plate is arranged on the top of the workbench. A lifting mechanism is arranged on the vertical plate. A cutting mechanism is connected to the lifting mechanism. A guiding groove is formed on the top of the workbench. A plurality of conveying mechanisms are arranged in the guiding groove. Four guiding mechanisms are symmetrically arranged on the top of the workbench. The cutting mechanism is located between the four guiding mechanisms. The advantages are as follows: The hose is placed on the top of a plurality of conveying wheels. The electric push rod pushes the guiding frame to move, and the guiding frame drives the guiding wheel to move. The guiding wheels arranged on both sides of the hose can limit the hose to prevent the hose from running off during conveyance and can adapt to the conveyance of hoses of different sizes.

[0003] In the prior art including the above patent, most optimizations and improvements are made for the accuracy of cutting and conveyance, reducing the deformation at the cut of the hose, etc. However, in actual processing, the cutting blade will... When cutting the hose, 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 treatment, but also the blade is easy to scratch the hands of workers during the treatment. This will not only delay the production progress but also increase the risk to the hands of workers. Moreover, it cannot be adapted to hoses of different hardnesses to further prevent the blade from getting stuck. Summary of the Invention

[0004] The problem to be solved by the present invention is: When cutting a hose with a hard texture and a thick wall, it is not easy to prevent the occurrence of knife jamming.

[0005] To solve the above technical problems, the technical solution of the present invention is: A fully automatic hose cutting machine that prevents the cutting edge from jamming the knife, including a feeding groove and a hydraulic component located between the two feeding grooves. The feeding grooves are symmetrically arranged along the center line of the hydraulic component. The hydraulic component is composed of a hydraulic rod, a mounting frame, and related control elements. The lower end of the hydraulic rod of the hydraulic component is fixedly provided with a fixed part in the protection component. The protection component has two parts. One part is the fixed part installed at the lower end of the hydraulic rod, and the other part is a pushing component located below the fixed part. The protection component is used to assist in positioning and cutting the hose and prevent knife jamming. A blade in the cutting component is arranged between the pushing components of the protection component. A cleaning component is arranged inside the protection component. The cleaning component is used to clean the blade and discharge materials and assist the protection component in working.

[0006] Preferably, the protection component includes a mounting plate installed at the lower end of the hydraulic rod. The mounting plate is cross-shaped. In the middle of the interior of the mounting plate, a limiting rod is fixedly arranged. There are four limiting rods in total. The limiting rods are symmetrically arranged along the center line of the mounting plate. Springs are arranged around the limiting rods. A clamping block is slidably arranged below the mounting plate.

[0007] Preferably, the upper end of the clamping block is located inside the mounting plate and is slidably connected to the limiting rod. The two ends of the spring are respectively fixedly connected to the mounting plate and the clamping block. A guiding block is arranged below the clamping block. The upper end of the guiding block is provided with an inclined surface. The mounting plate, the limiting rod, the spring, the clamping block and the guiding block are the material pushing components in the protection component.

[0008] Preferably, the protection component further includes a housing. The housing is located directly below the mounting plate. The upper end of the housing is fixedly connected to the guiding block by bolts. A protective cover is arranged inside the housing. There are two protective covers symmetrically arranged along the center line of the housing. Fixed blocks are fixedly arranged on the outer sides of the protective covers. The fixed blocks are symmetrically arranged along the center line of the protective covers.

[0009] Preferably, limiting blocks are arranged on both sides of the fixed block. The number of the limiting blocks is the same as that of the fixed blocks. The limiting blocks are all fixedly connected to the housing. The fixed block is connected to the limiting block by bolts. The distance between the sliding groove in the middle of the limiting block and the protective cover gradually decreases from bottom to top.

[0010] Preferably, the protective covers are connected by rubber pads. There are two rubber pads in total. The rubber pads only serve to block wind. The rubber pads can be stretched as the protective covers move. Air outlets are opened at the upper ends of the protective covers. The air outlets are all opened on the inclined surfaces of the protective covers. The housing, the protective covers, the fixed blocks, the limiting blocks, the rubber pads and the air outlets in the protection component are the material pushing parts.

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

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

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

[0014] Preferably, a scraping blade is fixedly arranged inside the protective cover below the impeller. There are four groups of scraping blades in total. One side of the scraping blade close to the cutting blade is in contact with and slidably connected to the cutting blade. The other side of the scraping blade is provided with a cavity through the protective cover, and the cavity is only communicated with the scraping blade and the air outlet.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) Under the action of the protection component, first, the rubber hose can be cut without significantly changing the shape of the rubber hose at the cutting part, so that the contact area between the rubber hose and the cutting blade is reduced on the premise of the same displacement of the cutting blade, thereby reducing the probability of blade jamming. Secondly, by stretching the rubber hose to both sides, the rubber hose can rebound by its own elasticity after cutting, so that the contact area between the cutting blade and the rubber hose during cutting can be further reduced, and further reducing the probability of blade jamming. Moreover, the protective cover in the protection component can still reduce the effect of blade jamming when the device cuts rubber hoses with different textures. It is worth mentioning that the cutting blade adopts a sunken design and under the action of the protective sleeve, it can also prevent workers from accidentally touching the cutting blade, thereby improving the safety of the device, and the downward incision is also convenient for collecting debris and reducing the probability of splashing; (2) Through the setting of the cleaning component, first, the impeller can be used to provide wind power into the protection component, and the slag adhered to the edge of the cutting blade can be scraped off. This can not only collect the slag centrally, but also reduce the influence of the rubber hose slag on the cutting blade. The scraping blade can also be used to polish the edge of the cutting blade, so as to extend the service life of the cutting blade to a certain extent, and it only works for a short period of time after the cutting blade starts to rotate and stops rotating, so it will not over-polish the cutting blade. It is worth mentioning that the wind generated by the impeller can also guide the scraped slag to move to a designated position, so as to ensure the cleanliness of the work area and reduce the workload during cleaning.

[0027] The mounting bracket in 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 protection 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. The impeller 501 is fixedly connected to the motor shaft in the motor and its mounting bracket 401. There are two impellers 501 symmetrically arranged along the center line of the blade 402. The impeller 501 rotates synchronously with the blade 402.

[0030] The working principle and usage process of the present invention: When the rubber hose is transported through the feeding trough 1 and the position to be cut moves 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 close to the middle. As it moves downward, the rubber 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 part of the rubber hose to continue to move downward, but also move outward under the action of the guiding block 305. At this time, the rubber hose can be pulled to both sides. When the mounting plate 301 moves to a suitable position, the cutting component 4 is started to move the blade 402 upward to cut the rubber hose. During cutting, there are two situations in total: When the resilience of the rubber hose is good, the cut rubber hose can retract to both sides under the pulling force generated by the clamping block 304, so that the cut rubber hose can leave the range of the blade 402 in time, thereby reducing the contact area between the rubber hose and the blade 402 to a certain extent. When the resilience of the rubber hose is poor, as the blade 402 moves upward, the protective cover 307 can move upward together. During the upward movement of the protective cover 307, under the guiding action of the limit block 309, it can gradually move obliquely upward. Based on this, the inclined surface at the upper end of the protective cover 307 can be used to push the rubber hose to both sides, forcing the cut hose to move away from the blade 402; It should be noted that under the action of the self-gravity of the rubber hose on both sides of the cutting area and the friction force with the feeding groove 1, it will not move downward too much, so that the rubber hose at the cutting area can be normally stretched; When the blade 402 rotates, the two-sided impellers 501 rotate synchronously to generate centrifugal wind, and the air flow is discharged from the air outlet holes 311, the gap between the blade 402 and the protective cover 307, and the air outlet below the protective cover 307 respectively. This air flow blows the debris scraped off from the blade 402 by the scraping blade 502 to the lower part of the protective cover 307 for centralized treatment; at the same time, under the guiding action of the scraping blade 502, part of the debris is blown into the cavity 503 communicated with the air outlet of the protective cover 307. Using Bernoulli's principle, the air flow at the air outlet sucks out the air in the cavity 503, and together with the wind guided by the scraping blade 502, effectively reduces the probability of debris remaining in the cavity 503; It should be noted that the scraping of materials is only carried out when the protective cover (307) moves down to the lowest end.

[0031] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
