Description

Technical Field

[0001] The invention relates to the technical field of tool cleaning, in particular to a leather cutting knife dust removal and cleaning device. Background Art

[0002] Leather is a denatured, non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and feels comfortable. In leather processing, the leather needs to be cut into the required size and shape. The cutting knives used are divided into manual and automatic. Automatic cutting knives use a combination of electrical components and mechanical structures to drive the cutting knives to move back and forth or rotate, so that the leather can be cut. Manual cutting knives are operated by workers to cut the leather.

[0003] Whether it is a manual cutter or an automatic cutter, as the cutters are used for a long time, the animal fat on the leather will gradually adhere to the surface of the cutters. Since the fat has strong adhesion, the external dust and the leather scraps generated during the cutting process will adhere to the surface of the cutters, which will cause inconvenience in using the cutters, and the adhered dust will easily contaminate the leather.

[0004] After searching, the Chinese patent with authorization announcement number: CN106180017B discloses a high-efficiency cleaning device for leather cutting shears, including a bracket, a first slide rail, a connecting rod, a first slider, an electric push rod, a thumb cylinder, a swing rod, a gear, a support rod, a first spring and a second slide rail, etc.; an electric push rod is provided on the left side of the bracket, the left end of the electric push rod is connected to the first slider, the rear side of the electric push rod is provided with a first slide rail, and the first slider is arranged on the first slide rail.

[0005] Based on the above search and combined with actual problems, it was found that: the device can only clean the surface of the cutting blade by reciprocating the brush on the surface of the cutting blade. Although the dust can be cleaned quickly, since the leather contains a large amount of animal fat, the animal fat will not only adhere to the surface of the cutting blade itself, but also the animal fat will adhere to the external dust and leather scraps generated during the cutting process on the surface of the cutting blade. This makes it difficult for the device to thoroughly clean the surface of the cutting blade only by reciprocating the brush. If the surface of the cutting blade is not completely cleaned, the impurities adhered to its surface will easily contaminate the cut leather. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides a leather cutting knife dust removal and cleaning device through improvement. The technical solution of the present invention is:

[0032] like Figures 1 to 8 As shown, the embodiment of the present invention provides a leather cutting knife dust removal and cleaning device, including a bracket 1, and also including: two cleaning mechanisms symmetrically arranged, a merging mechanism is arranged between the two cleaning mechanisms and the bracket 1; the cleaning mechanism includes two side plates 101, four belt rollers 103 are rotatably connected between the two side plates 101, the outer sides of the four belt rollers 103 are connected by transmission belts 104, a second motor 102 is installed on one side of one of the side plates 101, and the driving end of the second motor 102 is fixed to one end of one of the belt rollers 103 The outer side of the transmission belt 104 is provided with a plurality of forking mechanisms for collecting debris, and the outer side of the transmission belt 104 is wrapped with a wiping cotton pad 105, and the wiping cotton pad 105 is provided with an opening 7 at the position corresponding to each forking mechanism, and the opposite sides of the two side panels 101 are provided with a boss structure for driving the forking mechanism to rotate; the forking mechanism includes a rotating rod 107 movably arranged on the outer side of the transmission belt 104, and a plurality of forking rods 113 are arranged on one side of the rotating rod 107; a detergent applying mechanism is arranged on the upper side of the two side panels 101.

[0033] Furthermore, the outer side of the rotating rod 107 is rotatably connected with a sleeve 106, and the sleeve 106 is fixed to the outer side of the transmission belt 104. Two push rods 108 are fixed at both ends of the rotating rod 107, and one end of the two push rods 108 is rotatably connected with a drag reduction roller 112. Two torsion springs 109 are provided at both ends of the outer side of the rotating rod 107, and the rotating rod 107 is elastically connected to the sleeve 106 through the torsion spring 109.

[0034] The rotating rod 107 can drive the forking rod 113 to rotate, so that it flips back and forth between a horizontal angle and an inclined angle. When the rotating rod 107 drives multiple forking rods 113 on one side thereof to rotate to an inclined angle, leather scraps adhered to the surface of the cutting blade can be forked, thereby separating the leather scraps from the cutting blade.

[0035] Furthermore, the boss structure includes two guide plates 110 slidably connected to one side of the side plate 101 at both ends, and two guide inclined surfaces 111 that can roll with the drag reduction roller 112 are symmetrically arranged at both ends of the two guide plates 110, and the two guide plates 110 are elastically connected to the side plate 101;

[0036] When each fork-taking mechanism moves to the lower side of the side plate 101 close to one end of the slat 301 along with the transmission belt 104, the two drag reducing rollers 112 of the fork-taking mechanism contact the lower sides of the two guide plates 110 respectively. The two drag reducing rollers 112 first contact the guide slope 111 at one end of the two guide plates 110. Under the guiding action of the guide slope 111, the two drag reducing rollers 112 push the ends of the two push rods 108, so that the two push rods 108 drive the rotating rod 107 to rotate a certain angle. Through the rolling cooperation between the drag reducing rollers 112 and the guide slope 111, the friction between the push rod 108 and the guide slope 111 can be reduced, and the rotating rod 107 can drive the multiple fork-taking rods 113 on one side thereof to rotate a certain angle from the original horizontal angle to the direction close to the cutting knife to form an inclined state.

[0037] Furthermore, the cleaning agent applying mechanism includes two vertical plates 201 fixed on the upper sides of the two side plates 101, one end of each of the two vertical plates 201 is provided with a first slide groove 202, the inner sides of the two first slide grooves 202 are slidably connected with first sliders 203, a hollow roller 204 is rotatably connected between the two first sliders 203, the outer side of the hollow roller 204 is evenly provided with a plurality of small holes 205, one end of each of the two first sliders 203 is respectively connected to the inner side of the two first sliders 203 through a first spring 211. The ends are elastically connected, a storage cylinder 206 is also fixed on one side of one of the vertical plates 201, a piston plate 208 is slidably connected to the inner side of the storage cylinder 206, one side of the piston plate 208 is elastically connected to the inner side of the storage cylinder 206 through a piston spring 209, one end of the hollow roller 204 is connected to the inner side of the storage cylinder 206 through a flexible connecting pipe 207, a filling pipe 210 is inserted on one side of the storage cylinder 206, and a one-way valve with the conduction direction pointing to the inner side of the storage cylinder 206 is arranged on the inner side of the filling pipe 210;

[0038] The detergent applying mechanism can evenly apply the detergent on the surface of the wiping cotton pad 105, and the detergent can gradually penetrate into the pores in the wiping cotton pad 105, thereby improving the cleaning effect of the wiping cotton pad 105 on the grease on the surface of the cutting knife and reducing the adhesion of leather scraps and dust.

[0039] Furthermore, the two vertical plates 201 are provided with second slide grooves 212 at one end relative to the two first slide grooves 202, the inner sides of the two second slide grooves 212 are slidably connected with second sliders 213, a squeezing roller 214 is rotatably connected between the two second sliders 213, and one end of the two second sliders 213 is elastically connected to the inner ends of the two second slide grooves 212 respectively through second springs 215;

[0040] The two second springs 215 have a relatively large elastic force, and the second springs 215 apply a relatively large thrust to the squeezing roller 214 through the two second sliders 213, so that the squeezing roller 214 can be pressed against the surface of the wiping cotton pad 105, so that the thickness of the wiping cotton pad 105 is compressed to a certain extent, so that the detergent mixed with grease in the internal pores of the wiping cotton pad 105 can be squeezed outward, so that the wiping cotton pad 105 can then absorb and penetrate the clean detergent again, thereby ensuring the cleaning effect of the wiping cotton pad 105 on the surface of the cutting knife.

[0041] Furthermore, the merging mechanism includes a first motor 2 installed at one end of the outer side of the bracket 1, a threaded shaft 3 rotatably connected to the inner side of the bracket 1, and two cross guide rods 6 fixed to the inner side of the bracket 1, two threaded sliders 4 are slidably connected to the outer ends of the two cross guide rods 6, and the outer ends of the threaded shaft 3 are respectively penetrated and rotatably connected to the inside of the two threaded sliders 4 through two external threads in opposite directions, the driving end of the first motor 2 is fixedly connected to one end of the threaded shaft 3, and the two ends of the two threaded sliders 4 are respectively rotatably connected to one side of the two side plates 101 of the two cleaning mechanisms through four side connecting rods 5;

[0042] The merging mechanism is used to drive the two cleaning mechanisms to merge or separate. When the two cleaning mechanisms are merged, the two wiping cotton pads 105 can be respectively attached to the two side surfaces of the cutting knife, so that the debris on the surface of the cutting knife can be wiped off well.

[0043] Furthermore, a slat 301 is fixed at one end of one side of the two cleaning mechanisms, two sliding rods 302 are slidably inserted at both ends of the two slats 301, a top plate 303 and a bottom plate 305 are fixed at both ends of the four sliding rods 302, and the four sliding rods 302 are elastically connected to one side of the two slats 301 through compression springs 304;

[0044] When the two cleaning mechanisms merge, the two slats 301 on one side of the two cleaning mechanisms merge, respectively driving the four slide bars 302 and the four bottom plates 305 to merge, until the four bottom plates 305 are clamped on the two side surfaces of the cutting knife from both sides. At the same time, as the two cleaning mechanisms continue to merge, the four clamping springs 304 are compressed, and the four clamping springs 304 continue to apply pressure to the four bottom plates 305, respectively, so that the four bottom plates 305 can clamp the two sides of the cutting knife, thereby fixing the cutting knife to prevent the cutting knife from sliding during cleaning and affecting the cleaning effect.

[0045] Working principle: when the cutting knife needs to be cleaned, the cutting knife is placed at the position corresponding to the two slats 301 between the two cleaning mechanisms, and then the first motor 2 of the merging mechanism is controlled to run and drive the threaded shaft 3 to rotate. Since the outer ends of the threaded shaft 3 are respectively penetrated and rotatably connected to the inside of the two threaded sliders 4 through two external threads in opposite directions, the threaded shaft 3 can drive the two threaded sliders 4 to move in opposite directions along the outer sides of the two cross guide rods 6 through the external threads when the threaded shaft 3 rotates. The two threaded sliders 4 then drive the two cleaning mechanisms to merge or separate synchronously through the four side connecting rods 5. When the two cleaning mechanisms merge, the two slats 301 on one side of the two cleaning mechanisms merge, respectively driving the four slide bars 302 and the four bottom plates 305 to merge until the four bottom plates 305 are clamped on the two sides of the cutting knife from both sides. At the same time, as the two cleaning mechanisms continue to merge, the four clamping springs 304 are compressed, and the four clamping springs 304 continue to apply pressure to the four bottom plates 305, so that the four bottom plates 305 can clamp the two sides of the cutting knife, so that the cutting knife can be fixed to prevent the cutting knife from sliding during cleaning and affecting the cleaning effect.

[0046] When the two cleaning mechanisms are combined, the cutting knife is first clamped and fixed. After being fixed, as the two cleaning mechanisms continue to be combined, the two transmission belts 104 of the two cleaning mechanisms gradually approach the two sides of the cutting knife. At the same time, the two second motors 102 of the two cleaning mechanisms rotate in the opposite direction, respectively driving the eight belt rollers 103 to rotate in the opposite direction. The eight belt rollers 103 drive the two transmission belts 104 to rotate in the opposite direction. The rotation direction of the two transmission belts 104 points to the direction of the forking rod 113 in each forking mechanism. The two transmission belts 104 and the two wiping cotton pads 105 of the two cleaning mechanisms gradually approach the two sides of the cutting knife.

[0047] When each fork-taking mechanism moves to the lower side of the side plate 101 close to one end of the slat 301 along with the transmission belt 104, the two drag-reducing rollers 112 of the fork-taking mechanism respectively contact the lower sides of the two guide plates 110 close to one end of the slat 301, and the two drag-reducing rollers 112 first contact the guide slope 111 at one end of the two guide plates 110. Under the guiding action of the guide slope 111, the two drag-reducing rollers 112 push the ends of the two push rods 108, so that the two push rods 108 drive the rotating rod 107 to rotate a certain angle. The friction between the push rod 108 and the guide slope 111 can be reduced through the rolling cooperation between the drag-reducing rollers 112 and the guide slope 111, and the rotating rod 107 can drive the multiple fork-taking rods 113 on one side thereof to rotate a certain angle from the original horizontal angle to the direction close to the cutting knife to form an inclined state (such as Figure 8 As shown in the state shown in the figure, when the inclined fork-taking rod 113 gradually approaches the surface of the cutting knife as a whole along with the cleaning mechanism, the transmission belt 104 drives the multiple fork-taking rods 113 of the fork-taking mechanism to move horizontally, and each fork-taking rod 113 can fork up the leather scraps adhering to the surface of the cutting knife, and can support the leather scraps on the upper side of the multiple fork-taking rods 113. When the drag-reducing roller 112 of the fork-taking mechanism is separated from the lower side of the guide plate 110 at one end, the elastic force of the torsion spring 109 drives the rotating rod 107 to rotate in the opposite direction by a certain angle to reset (as shown in the state shown in the figure). Figure 6 The plurality of forking rods 113 are driven to rotate in the opposite direction and return to the original horizontal angle. At the same time, the plurality of forking rods 113 can clamp the forked leather scraps between them and the transmission belt 104, and can carry the forked leather scraps to the end of the cleaning mechanism away from the slat 301. When the forking mechanism contacts the lower side of the guide plate 110 away from the end of the slat 301, according to the above principle, the rotating rod 107 and the forking rod 113 will rotate again, so that the plurality of forking rods 113 will rotate from the horizontal angle to the inclined angle again, so that the forked leather scraps can be unloaded downward, and the leather scraps fall to the ground or the upper side of the bracket 1, so that the scraps adhered to the surface of the cutting knife that needs to be cleaned can be quickly cleaned in advance, so as to prevent the leather grease from adhering the leather to the surface of the cutting knife and affecting the cleaning effect of the cutting knife, thereby facilitating improving the cleaning effect of the cutting knife;

[0048] As the two cleaning mechanisms continue to move, until the two wiping cotton pads 105 are in contact with the two side surfaces of the cutting knife respectively, the multiple forking rods 113 of each forking mechanism are subjected to the reaction force of the cutting knife, so that each forking rod 113 rotates to a horizontal angle, driving the rotating rod 107 and the push rod 108 to rotate, and the two push rods 108 push the guide plate 110 away from the cutting knife through the two resistance reducing rollers 112. At this time, the forking rods 113 of the forking mechanism located on both sides of the cutting knife can be at a horizontal angle. At this time, the two wiping cotton pads 105 rotating in opposite directions in the two cleaning mechanisms can respectively wipe the two side surfaces of the cutting knife continuously, so that the cutting knife can be cleaned;

[0049] In each rotation cycle, before the wiping cotton pad 105 comes into contact with the cutting blade, various parts of the surface of the wiping cotton pad 105 will slide under the hollow roller 204 of the detergent coating mechanism in turn, and the two first springs 211 of the detergent coating mechanism apply thrust to the two first sliders 203, and the two first sliders 203 apply thrust to the hollow roller 204, so that the hollow roller 204 can fit exactly on the surface of the wiping cotton pad 105 without squeezing and deforming the wiping cotton pad 105. At the same time, the inner side of the storage cylinder 206 is filled with detergent, and the piston spring 209 applies thrust to the piston plate 208, which activates the cleaning agent. The plug plate 208 applies a thrust to the detergent inside the storage tube 206, so that the detergent flows into the inside of the hollow roller 204 through the connecting tube 207, and then the detergent is evenly applied to one side of the wiping cotton pad 105 through the plurality of small holes 205, and the detergent gradually penetrates into the fine holes inside the wiping cotton pad 105. When the wiping cotton pad 105 wipes the surface of the cutting knife, the leather grease on the surface of the cutting knife can be cleaned more efficiently with the detergent that penetrates inside, and the adhesion of dust can be reduced, so that the dust on the surface of the cutting knife can be quickly and effectively cleaned, and the cleaning effect of the cutting knife is further improved;

[0050] After the wiping cotton pad 105 wipes the surface of the cutting blade, the wiping cotton pad 105 will rotate to the lower side of the squeezing roller 214 and slide along the lower side of the squeezing roller 214. The elastic force of the two second springs 215 is relatively large. The second springs 215 apply a relatively large thrust to the squeezing roller 214 through the two second sliders 213, so that the squeezing roller 214 can be pressed against the surface of the wiping cotton pad 105, so that the thickness of the wiping cotton pad 105 is compressed to a certain extent, so that the detergent mixed with grease in the pores inside the wiping cotton pad 105 can be squeezed outward, so that the wiping cotton pad 105 can then absorb and penetrate the clean detergent again, thereby ensuring the cleaning effect of the wiping cotton pad 105 on the surface of the cutting blade.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
