DETAILED DESCRIPTION

[0034] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The present invention provides a technical solution: referring to Figure 1 - Figure 5 , a tool holder installation device in a tool disclosed in the present invention comprises a housing 1;

[0036] Also includes:

[0037] The installation component 2 includes a conveyor belt 21, which is arranged in the housing 1. The conveyor belt 21 is mainly composed of a plurality of elastic plates 211, a rubber ring belt 212 and a plurality of rubber strips 213. The plurality of elastic plates 211 are fixedly mounted on the outer peripheral wall of the rubber ring belt 212, and each rubber strip 213 is arranged between two corresponding elastic plates 211 and is fixedly connected to the rubber ring belt 212 and the corresponding two elastic plates 211. The rubber ring belt 212 is provided with a driving mechanism 22, and the elastic plate 21 1 is provided with a storage groove 214, and a guide groove 215 is provided at the bottom of the storage groove 214. A first placement groove 23 and a second placement groove 24 are relatively fixedly installed and penetrated at a position corresponding to the storage groove 214 on the outer wall of the housing 1. A first soft plate 25 is fixedly installed in the groove wall of the first placement groove 23. A second soft plate 26 is fixedly installed in the plate wall of the elastic plate 211 at a position corresponding to the first soft plate 25, and the top side of the first soft plate 25 and the top side of the second soft plate 26 are both coplanar with the bottom of the storage groove 214.

[0038] The adsorption component 3 is disposed in the housing 1 and applies an adsorption limit constraint force to the blade in the storage slot 214;

[0039] The positioning component 4 is disposed in the housing 1 and applies an adsorption positioning constraint force to the tool holder in the second placement groove 24 .

[0040] In this embodiment, it should be noted that the elastic plate 211 is made of elastic plastic, the rubber strip 213 is made of elastic rubber material and has honeycomb holes inside to enhance the elasticity and expansion performance of the rubber strip 213, and the bottom side of the first placement groove 23 is provided with a support plate in an inclined shape, and the two ends of the support plate are respectively connected to the bottom side of the first placement groove 23 and the outer wall of the housing 1 to enhance the strength of the first placement groove 23 so that the first placement groove 23 can be stably maintained in a straight state;

[0041] When the improved rack installation device is used, when the bottom opening of the guide tube 27 is aligned with the storage slot 214, the blade at the bottom of the guide tube 27 falls into the storage slot 214, and at the same time, the adsorption component 3 can apply an adsorption constraint force to the blade, so that the blade is tightly attached to the bottom of the storage slot 214 and the blade is stably placed in the storage slot 214. The driving mechanism 22 is then started to drive the conveyor belt 21 to rotate intermittently, so that the blades in the guide tube 27 can be taken out in turn, and the positions of each blade in the housing 1 can be adjusted synchronously, so that the arrangement of the blades can be automatically completed, and the alignment operation between the blades and the knife holder can be quickly completed, thereby improving the installation efficiency of the knife holder, avoiding the contact between the operator's fingers and the blade, and improving the safety of the operator during the installation of the knife holder;

[0042] Before the blade moves to the position of the first placement groove 23, the operator places the tool holder in the second placement groove 24. Due to the mutual interference between the inner wall of the second placement groove 24 and the tool holder, the tail end opening of the tool holder is located at the corresponding position in the second placement groove 24. Then, when the blade moves between the first placement groove 23 and the second placement groove 24, the positioning component 4 is started to apply an adsorption constraint force to the tool holder, so that a great friction force is generated between the tool holder and the second placement groove 24, and the constraint positioning of the tool holder and the second placement groove 24 is automatically completed, and at the same time, the adsorption force of the adsorption component 3 on the blade is weakened. The operator does not need to manually limit the tool holder constraint, nor does the operator need to manually adjust the device. The device has a high degree of automation, which reduces the labor intensity of the operator.

[0043] After the tool holder is installed, the operator places the push slider in the first placement groove 23, and places the push slider on the first soft plate 25 and the second soft plate 26, then presses and pushes the push slider downward, and as the first soft plate 25 and the second soft plate 26 shrink, the push slider gradually moves downward so that the end of the push slider moves under the blade, and the operator can directly push the end of the push slider between the blade and the first soft plate 25 when pushing the push slider. After the round rod of the push slider moves to the bottom of the blade hole, stop pushing the push slider and slowly release it. The push slider is pressed, and as the first soft plate 25 and the second soft plate 26 are deformed and reset, the round rod on the push slider is directly inserted into the hole of the blade to complete the installation between the push slider and the blade. In this process, the blade is subjected to an adsorption force, so that the operator can easily push the blade to slide in the storage groove 214 when pushing the slider, and the front end of the blade is always in contact with the bottom of the storage groove 214 when inserted into the tool holder. During the assembly process of the push slider and the blade, the contact between the fingers and the blade is avoided, thereby improving the safety of the operator during the installation of the tool holder;

[0044] After the installation between the pushing slider and the blade is completed, the operator pushes the blade through the pushing slider so that the blade is gradually inserted into the tool holder. After the blade is completely inserted into the tool holder, the operator continues to push the pushing slider so that the pushing slider is also inserted into the tool holder synchronously, and then stops pushing the pushing slider. The assembly between the pushing slider, the blade and the tool holder is completed. Finally, the operator takes the tool holder out of the second placement slot 24 and inserts the rear end cover into the tail end opening of the tool holder to complete the assembly of the tool holder. During the installation process of the tool holder and the blade, the operator's hand will not come into contact with the blade, which is highly safe.

[0045] In a further preferred embodiment of the present invention, Figure 2 - Figure 4 As shown, the driving mechanism 22 includes two drivers 221, which are relatively fixedly mounted on the outer wall of the housing 1, and driving rollers 222 are provided at the four corners of the rubber ring belt 212, and the outer peripheral wall of each driving roller 222 is interference fit with the inner ring wall of the rubber ring belt 212, and both ends of the driving roller 222 rotate to penetrate the shell wall of the housing 1, and one end of the driving roller 222 close to the driver 221 is fixedly connected to the corresponding output end of the corresponding driver 221;

[0046] In this embodiment, it should be noted that the driving roller 222 can be made of plastic material to enhance the friction between the driving roller 222 and the rubber ring belt 212. The driver 221 is mainly composed of a housing, a plurality of gears and a motor. The two motors drive the four driving rods to rotate in the same direction through a plurality of gears.

[0047] according to Figure 3As shown, when the device is in use, two drivers 221 start to drive four drive rollers 222 to rotate intermittently. Due to the friction between the outer peripheral wall of the drive roller 222 and the inner wall of the rubber ring, the rotating drive roller 222 drives the conveyor belt 21 to rotate rapidly. Figure 2 and Figure 3 As shown, the intermittent rotation of the driving roller 222 can drive the conveyor belt 21 in the housing 1 to intermittently rotate a corresponding distance, and the interval time for the conveyor belt 21 to push the blade to move can be controlled by an external controller to adapt to the working habits of different users.

[0048] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, a material guide tube 27 is fixedly mounted on the top side of the housing 1, and the bottom side of the material guide tube 27 is in contact with the top side of the corresponding elastic plate 211;

[0049] In this embodiment, it should be noted that the above-mentioned material guide tube 27 is used to store blades;

[0050] according to Figure 2 As shown, during the use of the device, the operator inserts the stacked blades into the guide tube 27. Due to the restriction of the inner wall of the guide tube 27 on the blades and the gravity of the blades themselves, the blades fall vertically. Figure 2 and Figure 3 As shown, as the blade falls, the bottom blade in the guide tube 27 falls into the corresponding storage groove 214, so that the above-mentioned conveyor belt 21 can bring the blades out of the guide tube 27 one by one during the rotation process, and a large number of blades can be loaded at one time, which reduces the loading frequency of the blades and improves the installation efficiency of the tool holder.

[0051] In a further preferred embodiment of the present invention, Figure 1 - Figure 3 As shown, both sides of the rubber ring 212 and both ends of the elastic plate 211 are in contact with the inner wall of the housing 1, and the opposite surfaces of the first placement groove 23 and the second placement groove 24 are coplanar with the inner wall of the housing 1;

[0052] In this embodiment, according to Figure 2 and Figure 3 As shown, due to the support and limitation of the rubber ring belt 212 by the elastic plate 211, the side walls at both ends of the rubber ring belt 212 are always in contact with the inner wall of the housing 1, so that a relatively closed space is formed between the inner ring wall of the rubber ring belt 212 and the inner wall of the housing 1.

[0053] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 5As shown, the adsorption assembly 3 includes an air pump 31, which is arranged at the middle position in the rubber ring belt 212, and the exhaust end of the air pump 31 is fixedly penetrated through the shell wall of the shell 1, and two groups of adsorption holes 32 are relatively opened at the bottom of the storage tank 214, and some adsorption holes 32 in the two groups are staggered, and the interior of the adsorption hole 32 is communicated with the interior of the rubber ring belt 212;

[0054] In this embodiment, it should be noted that an air pressure monitoring sensor is installed on the inner wall of the housing 1 at a position corresponding to the air pump 31 through bolts to monitor the negative pressure strength in the housing 1;

[0055] according to Figure 2 and Figure 5 As shown, during the use of the device, the air pump 31 starts to continuously extract the gas between the inner wall of the rubber ring belt 212 and the inner wall of the shell 1, and adjusts the operating power of the air pump 31 according to the monitoring result of the air pressure monitoring sensor, so that a relatively stable negative pressure cavity is formed between the inner wall of the rubber ring belt 212 and the inner wall of the shell 1. Figure 2 and Figure 3 As shown, at this time, due to the obstruction of the blade, the top opening of the adsorption hole 32 on the elastic plate 211 on the bottom side of the blade is in an almost closed state, and the bottom opening of the adsorption hole 32 is communicated with the inside of the rubber ring sleeve, and a negative pressure cavity of corresponding strength is synchronously formed in the adsorption hole 32 at the bottom of the blade and in the air storage tank 47, thereby applying an adsorption constraint force to the blade, so that the blade fits tightly with the bottom of the storage tank 214 and is stably constrained in the storage tank 214, so as to avoid the blade in the storage tank 214 from conflicting with the inner wall of the guide tube 27 during the rotation of the conveyor belt 21, resulting in the blade being unable to be pushed out of the guide tube 27.

[0056] In a further preferred embodiment of the present invention, Figure 2 , Figure 7 , Fig. 9 and Fig.10 As shown, the positioning assembly 4 includes a soft pad 41, a mounting groove 42 is provided at the bottom of the second placement groove 24, and the bottom of the soft pad 41 is inserted into the mounting groove 42 and fixedly connected to the inner wall of the mounting groove 42, the corners of the top side of the soft pad 41 are arranged in an arc shape, and a plurality of adsorption positioning holes 43 are provided on the soft pad 41, and the spacing between two adjacent adsorption positioning holes 43 is equal;

[0057] In this embodiment, according to Figure 2 As shown, after the operator places the tool holder in the second placement groove 24, due to the mutual interference between the inner wall of the second placement groove 24 and the tool holder, the tail end opening of the tool holder is located at the corresponding position in the second placement groove 24, and due to the pressure of the tool holder on the soft pad 41, the soft pad 41 shrinks and deforms and retracts into the installation groove 42, so that the top side of the soft pad 41 is in close contact with the tool holder. Fig. 9 and Fig.10As shown, an adsorption constraint force can be applied to the tool holder through the adsorption hole 32 and the negative pressure cavity formed in the installation groove 42, so that the tool holder and the soft pad 41 are more closely attached, and a great friction force is generated between the tool holder and the second placement groove 24, so that when the operator pushes the blade and the pushing slider into the tool holder, the position of the tool holder will not change, affecting the installation operation of the tool holder.

[0058] In a further preferred embodiment of the present invention, Figure 2 - Figure 4 As shown, a sealing plate 44 is provided inside the rubber ring belt 212, and the sealing plate 44 is located on the top side of the air pump 31, both ends of the sealing plate 44 are fixedly connected to the inner wall of the housing 1, and the top side of the sealing plate 44 is in contact with the inner wall of the rubber ring belt 212, and the corners of the sealing plate 44 are arranged in an arc shape;

[0059] In this embodiment, it should be noted that the sealing plate 44 can be made of a hard material such as a hard metal material or a hard plastic;

[0060] according to Figure 3 and Figure 4 As shown, during the movement of the elastic plate 211, when the blade gradually moves to the position of the first placement slot 23, the elastic plate 211 on the bottom side of the blade gradually moves to the sealing plate 44. Due to the fit between the top side of the sealing plate 44 and the inner wall of the rubber ring band 212, the sealing plate 44 can directly block the bottom opening of the adsorption hole 32 on the elastic plate 211, and cooperate with the above-mentioned blade to block the top opening of the adsorption hole 32, so that a relatively closed space is formed in the adsorption hole 32 and the air storage tank 47, and the connection between the adsorption hole 32 at the position of the second placement slot 24 and the rubber ring band 212 is automatically cut off, and the operator does not need to perform other operations.

[0061] In a further preferred embodiment of the present invention, Figure 5 , Figure 8 and Fig. 9 As shown, a connecting pipe 45 is fixedly installed in the sealing plate 44, and several exhaust ends of the connecting pipe 45 are respectively extended to the bottom ends of the corresponding adsorption holes 32, and several exhaust ends of the connecting pipe 45 are coplanar with the top side of the sealing plate 44, and the exhaust end of the connecting pipe 45 passes through the shell wall of the outer shell 1 and extends into the installation groove 42, and the connecting pipe 45 is fixedly connected to the shell wall of the outer shell 1 and the groove wall of the second placement groove 24;

[0062] In this embodiment, according to Figure 7 and Figure 8 As shown, after the elastic plate 211 moves between the first placement groove 23 and the second placement groove 24, the bottom end opening of the adsorption hole 32 is just located at the top side of the exhaust end of the connecting pipe 45, and the adsorption hole 32 is connected to the installation groove 42 through the connecting pipe 45. Figure 7 - Fig.10As shown, due to the pressure difference between the inside of the adsorption hole 32 and the inside of the mounting groove 42, part of the gas in the mounting groove 42 quickly passes through the one-way valve 46 and the connecting pipe 45 and flows into the adsorption hole 32 at this position, so as to reduce the negative pressure intensity in the adsorption hole 32 at this position, and at the same time, a negative pressure cavity of corresponding intensity is synchronously formed in the mounting groove 42 and the adsorption positioning hole 43, exerting an adsorption constraint force on the tool holder, without the need to set up additional structures such as additional gas extraction structures and electric control mechanisms, thereby reducing the production cost of the device.

[0063] In a further preferred embodiment of the present invention, Figure 3 , Figure 6 and Fig.11 As shown, an air inlet groove 48 is provided on the side wall of the guide groove 215 at a position corresponding to the adsorption hole 32, and the interior of the air inlet groove 48 is communicated with the interior of the corresponding adsorption hole 32;

[0064] In this embodiment, according to Fig.11 As shown, during the process of assembling the pushing slider and the blade, the outside air passes through the guide groove 215 and flows into the adsorption hole 32 from the position of the air inlet groove 48, further reducing the negative pressure strength in the adsorption hole 32 at this position, thereby further reducing the resistance encountered by the blade when sliding in the storage groove 214, so that the operator can more easily push the blade to slide in the storage groove 214 when pushing the slider, and the front end of the blade is always in contact with the bottom of the storage groove 214 when inserted into the tool holder.

[0065] In a further preferred embodiment of the present invention, Fig. 9 and Fig.10 As shown, a one-way valve 46 is fixedly installed at the air inlet end of the connecting pipe 45, and two air storage tanks 47 are relatively opened at positions corresponding to the two groups of adsorption holes 32 in the elastic plate 211, and the interior of each air storage tank 47 is communicated with the interior of the corresponding adsorption hole 32;

[0066] In this embodiment, according to Figure 7 - Fig.10 As shown, in the process of further reducing the negative pressure intensity in the adsorption hole 32, due to the obstruction of the one-way valve 46, the gas in the adsorption hole 32 will not flow back into the installation groove 42 through the connecting pipe 45, so that the further weakening of the adsorption force on the blade will not affect the restraining and limiting strength of the tool holder.

[0067] Working principle: When the improved knife holder installation device is used, the operator inserts the stacked blades into the guide tube 27. Due to the restriction of the inner wall of the guide tube 27 on the blades and the gravity of the blades themselves, the blades fall vertically until the bottom blades fall into the corresponding storage slot 214.

[0068] After the blade is loaded, the air pump 31 is started first to continuously extract the gas between the inner wall of the rubber ring belt 212 and the inner wall of the shell 1, and the operating power of the air pump 31 is adjusted according to the monitoring result of the air pressure monitoring sensor, so that a relatively stable negative pressure cavity is formed between the inner wall of the rubber ring belt 212 and the inner wall of the shell 1. At this time, due to the shielding of the blade, the top opening of the adsorption hole 32 on the elastic plate 211 at the bottom side of the blade is in an almost closed state, and the bottom opening of the adsorption hole 32 is communicated with the inside of the rubber ring sleeve, and the adsorption hole 32 at the bottom of the blade and the air storage A negative pressure cavity of corresponding strength is simultaneously formed in the groove 47, thereby exerting an adsorption constraint force on the blade, so that the blade fits tightly with the bottom of the storage groove 214 and is stably constrained in the storage groove 214, and at the same time, the external gas flows into the conveyor belt 21 through the air inlet groove 48 and the adsorption hole 32 at the position of the blade to replenish part of the gas lost in the conveyor belt 21, and the adsorption holes 32 of the other part are not blocked by the blade, so the external gas directly flows into the conveyor belt 21 through the adsorption holes 32 to replenish another part of the gas lost in the conveyor belt 21;

[0069] Then the driver 221 starts to drive the four driving rollers 222 to rotate intermittently. Due to the friction between the outer peripheral wall of the driving roller 222 and the inner wall of the rubber ring, the rotating driving roller 222 drives the conveyor belt 21 to rotate rapidly. Through the intermittent rotation of the driving roller 222, the conveyor belt 21 located in the housing 1 can be driven to rotate intermittently for a corresponding distance.

[0070] According to the above, during the intermittent rotation of the conveyor belt 21, since the blades are adsorbed and restrained in the storage slot 214, the blade at the bottom can be directly pushed out of the guide tube 27 during the rotation of the conveyor belt 21, and then when the subsequent blades are aligned with the next storage slot 214, due to the effect of the blades' own gravity, the subsequent blades fall into the subsequent storage slots 214 in sequence, and finally, during the intermittent rotation of the conveyor belt, the blades in the guide tube 27 can be directly taken out in sequence;

[0071] Before the blade moves to the position of the first placement slot 23, the operator needs to place the knife holder in the second placement slot 24. Due to the mutual interference between the inner wall of the second placement slot 24 and the knife holder, the tail end opening of the knife holder is located at the corresponding position in the second placement slot 24. Due to the pressing of the knife holder on the soft pad 41, the soft pad 41 shrinks and deforms and retracts into the installation slot 42, so that the top side of the soft pad 41 is tightly attached to the knife holder, and the installation of the knife holder is completed.

[0072] When the blade gradually moves to the position of the first placement groove 23, the elastic plate 211 on the bottom side of the blade gradually moves to the sealing plate 44. Due to the fit between the top side of the sealing plate 44 and the inner wall of the rubber ring belt 212, the sealing plate 44 can directly block the bottom opening of the adsorption hole 32 on the elastic plate 211, and cooperate with the above-mentioned blade to block the top opening of the adsorption hole 32, so that a relatively closed space is formed in the adsorption hole 32 and the air storage tank 47. After the conveyor belt 21 stops rotating, the bottom opening of the adsorption hole 32 is just located on the top side of the exhaust end of the connecting pipe 45. The adsorption hole 32 is connected to the installation tank 47 through the connecting pipe 45. The mounting groove 42 is connected. Due to the pressure difference between the inside of the adsorption hole 32 and the inside of the mounting groove 42, part of the gas in the mounting groove 42 quickly passes through the one-way valve 46 and the connecting pipe 45 and flows into the adsorption hole 32 at this position, so as to reduce the negative pressure strength in the adsorption hole 32 at this position, and at the same time, a negative pressure cavity of corresponding strength is formed in the mounting groove 42 and the adsorption positioning hole 43, and an adsorption constraint force is applied to the tool holder, so that the tool holder and the soft pad 41 are more closely attached, and a great friction force is generated between the tool holder and the second placement groove 24, and the constraint positioning of the tool holder and the second placement groove 24 is automatically completed;

[0073] After the constraint positioning of the tool holder is completed, the operator places the push slider in the first placement groove 23, and places the push slider on the first soft plate 25 and the second soft plate 26, then presses downward and pushes the push slider, and as the first soft plate 25 and the second soft plate 26 shrink, the push slider gradually moves downward so that the end of the push slider moves to under the blade, and the operator can directly push the end of the push slider between the blade and the first soft plate 25 when pushing the push slider. After the round rod of the push slider moves to under the hole of the blade, stop pushing the push slider and slowly release the pressure of the push slider. At this time, as the first soft plate 25 and the second soft plate 26 expand and deform to reset, the round rod on the push slider is directly inserted into the hole of the blade;

[0074] During the process of assembling the push slider and the blade, the outside air flows into the adsorption hole 32 from the position of the air inlet groove 48, further reducing the negative pressure strength in the adsorption hole 32 at this position, thereby further reducing the resistance encountered by the blade when sliding in the storage groove 214, so that the operator can easily push the blade to slide in the storage groove 214 when pushing the slider, and the front end of the blade always fits the bottom of the storage groove 214 when inserted into the blade holder;

[0075] After the installation between the push slider and the blade is completed, the operator pushes the blade through the push slider so that the blade is gradually inserted into the blade holder. After the blade is completely inserted into the blade holder, the operator continues to push the push slider so that the push slider is also inserted into the blade holder synchronously, and then stops pushing the push slider. The assembly between the push slider, the blade and the blade holder is completed.

[0076] It should be noted that, during the above-mentioned process of assembling the push slider, the blade and the blade holder, as the blade is moved away from the top opening of the adsorption hole 32 at the position, the outside air flows from the top opening of the adsorption hole 32 at the position into the adsorption hole 32 at the position and the air storage tank 47, so as to release the negative pressure state in the adsorption hole 32 at the position and the air storage tank 47;

[0077] After the assembly of the push slider, the blade and the tool holder is completed, the operator holds the tool holder and lifts one end of the tool holder to gradually tilt the tool holder. At this time, the outside air flows into the adsorption positioning hole 43 and the mounting groove 42 from the top opening of the adsorption positioning hole 43 to release the negative pressure state in the adsorption positioning hole 43 and the mounting groove 42. After the operator takes the tool holder out of the second placement groove 24, the operator inserts the rear end cover into the tail end opening of the tool holder to complete the assembly of the tool holder and the blade. According to the above repeated operations, the assembly of the tool holder and the blade can be completed continuously.
