Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpening machines, and particularly relates to a feeding mechanism of a full-automatic knife sharpening machine. Background Art

[0002] When a tool is used for a long time, irregular deformation will occur on the surface of the tool disc, and uneven rust will be distributed, resulting in difficulty in leveling and stable fixation when the tool disc is fixed. The traditional grinding of tools is completed manually by people. Manual knife sharpening has low work efficiency, small output, large labor consumption, requires a lot of manpower, and it is difficult to ensure the consistency of the ground tools, so a knife sharpening machine appears.

[0003] In the Chinese utility model patent application publication specification CN 105397630 A, a feeding device of a full-automatic knife sharpening machine is disclosed. In the feeding device of the full-automatic knife sharpening machine, the feeding push plate moves forward under the push of a spring to push the lowermost surgical blade forward and move it out of the loading vertical groove, which is convenient for clamping and knife sharpening. However, there are still the following deficiencies, such as:

[0004] Since this device is used for sharpening surgical knives, the slider and the vertical groove are set too narrow, and the grinding range of the knife is controlled small, resulting in that this device cannot adapt to most knife types on the market and has strict requirements for the shape of the knife, and there are damage effects when grinding other knives except surgical knives. Therefore, we propose a feeding mechanism of a full-automatic knife sharpening machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a feeding mechanism of a full-automatic knife sharpening machine, which has the effect of improving the adaptability of the knife sharpening machine to knife types.

[0006] The above technical purpose of the utility model is achieved by the following technical solutions: a feeding mechanism of a full-automatic knife sharpening machine, including a knife sharpening table, a knife placing shell is fixedly connected to the top of the knife sharpening table, a knife groove is opened inside the knife placing shell, an outlet opening is opened on the left side of the knife placing shell, a motor I is fixedly connected to the right side of the knife sharpening table, an electric pneumatic rod is fixedly connected to the left output end of the motor I, and a fixed signal transmission rod is fixedly connected to the back of the motor I.

[0007] By setting the knife groove and the electric pneumatic rod, specifically, the user can place the tool shape template into the knife groove according to the shape of the tool to be ground, and then place the knife into the template to fix the knife. The knives will stack together due to their own gravity. When the electric pneumatic rod is started, the electric pneumatic rod moves the knife forward to the outlet opening opened on the left side of the knife groove by pushing the push plate, which not only improves the adaptability of the machine to knife types, but also completes the automatic feeding of the knife body, reduces the labor cost, and improves the working speed and working efficiency of knife sharpening.

[0008] Furthermore, several air compression ports are provided inside the knife placement shell. Two air outlets are provided on the left side of the knife placement shell. Two small pneumatic rods are fixedly connected to the air outlets on the left side of the knife placement shell. Pressure fixing plates are respectively fixedly connected to the bottom output ends of the two small pneumatic rods. A conveying port is provided at the bottom right of the knife placement shell, and an adjustment port is provided on the right side of the knife placement shell.

[0009] By setting the pressure fixing plate, specifically, when the electric pneumatic rod pushes the push plate, it will also push the pressure block. The rubber pneumatic plate fixedly connected to the left side of the pressure block generates pressure on the small pneumatic rod by pushing air, causing the small pneumatic rod to move. The bottom of the small pneumatic rod pushes the pressure fixing plate to fix the knife, so that the knife will not move randomly during the grinding process, improving the accuracy of knife grinding and preventing the situation of unqualified knife quality caused by random movement of the knife.

[0010] Furthermore, a push plate is fixedly connected to the left output end of the electric pneumatic rod. Pressure blocks are respectively fixedly connected to the front and back sides of the push plate, and a rubber pneumatic plate is fixedly connected to the left side of the pressure block.

[0011] By setting the push plate and the pressure block, the linkage effect between the knife and the fixing plate is achieved, which can better fix the tool to be ground and prevent the uneven grinding caused by random movement of the knife.

[0012] Furthermore, a fixing block is provided on the left side of the knife grinding table. An intermittent motor is fixedly connected to the top of the fixing block. A connecting rod is fixedly connected to the right output end of the intermittent motor. A rotating shaft is fixedly connected to the right side of the connecting rod. A track is connected to the outer surface of the rotating shaft in a transmission manner. A support plate is provided on the front side of the connecting rod.

[0013] By setting the intermittent motor and the track, the transportation effect of the knife after grinding is achieved, avoiding the embarrassing situation that the tool still needs to be taken away manually after grinding, improving the transportation speed of the knife after grinding, and reducing the labor cost.

[0014] Furthermore, a support frame is fixedly connected to the top left of the knife grinding table. A second motor is fixedly connected to the back of the support frame. A threaded rod is fixedly connected to the output end of the second motor. Two sliding rods are fixedly connected to the front of the support frame. A knife grinder is slidably connected to the outer surfaces of the two sliding rods. A knife grinding motor is fixedly connected to the top of the knife grinder. A telescopic signal transmission rod is fixedly connected to the top of the second motor. A telescopic signal transmission rod is fixedly connected to the left side of the knife grinding motor. A grinding stone is fixedly connected to the output end of the knife grinding motor.

[0015] By setting the threaded rod and the grinding stone, the uniformity and coherence of knife grinding are achieved, avoiding the situations of uneven knife grinding and unqualified knife grinding quality, and improving the quality and speed of knife grinding.

[0016] Further, an adjustment opening is provided on the right side of the tool placement housing, and an opening is provided at the bottom right side of the tool placement housing. The internal air compression opening of the tool placement housing is slidably connected to the pressure block, and the opening provided at the bottom right side of the tool placement housing is slidably connected to the push plate.

[0017] Through the adjustment opening on the right side of the tool placement housing, manual adjustment can be performed, achieving the effect that the tools are not neatly placed in the tool slots, avoiding the situation of unevenness during tool grinding, and improving the controllability and stability of the tools to be ground.

[0018] Further, the right side of the second motor is fixedly connected to the fixed signal transmission rod, and the knife grinder is in transmission connection with the threaded rod.

[0019] By providing the fixed signal transmission rod, signal transmission between the second motor and the first motor is achieved, avoiding the embarrassing situation of the second motor and the first motor working simultaneously, improving the linkage and signal transmission stability between the second motor and the first motor, and strengthening the coordination during the operation of the device.

[0020] The beneficial effects of the present utility model are as follows:

[0021] 1. By providing the tool slot and the electric air pressure rod, specifically, the user can place the tool shape template into the tool slot according to the shape requirements of the tool to be ground, and then place the tool into the template to fix the tool. The tools will stack together due to their own gravity. When the electric air pressure rod is started, the electric air pressure rod moves the tool forward to the cutting opening provided on the left side of the tool slot through the push plate, which not only improves the mechanical adaptability to the tool shape, but also completes the automatic feeding of the tool body, reducing the labor cost and improving the working speed and efficiency of knife grinding.

[0022] 2. By providing the pressure fixing plate, specifically, when the electric air pressure rod pushes the push plate, it also pushes the pressure block. The rubber air pressure plate fixedly connected to the left side of the pressure block generates pressure on the small air pressure rod by pushing air, causing the small air pressure rod to move. The bottom of the small air pressure rod pushes the pressure fixing plate to fix the tool, so that the tool will not move randomly during the grinding process, improving the accuracy of knife grinding and preventing the situation of unqualified tool quality caused by random movement of the tool.

Specific embodiments

[0032] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figure 1-7As shown in the figure, this utility model is a feeding mechanism for a fully automatic knife grinder, including a feeding mechanism for a fully automatic knife grinder, which includes a grinding table 1. A knife placement shell 11 is fixedly connected to the top of the grinding table 1. A knife groove 111 is opened inside the knife placement shell 11. An outlet opening is opened on the left side of the knife placement shell 11. A first motor 12 is fixedly connected to the right side of the grinding table 1. The left output end of the first motor 12 is fixedly connected to an electric pneumatic rod 121. A fixed signal transmission rod 125 is fixedly connected to the back of the first motor 12. By setting the knife groove 111 and the electric pneumatic rod 121, specifically, the user can place the tool shape template into the knife groove 111 according to the shape of the knife to be ground, and then place the knife into the template to fix the knife. The knives will stack together due to their own gravity. When the electric pneumatic rod 121 is started, the electric pneumatic rod 121 moves the knife forward to the outlet opening opened on the left side of the knife groove 111 by pushing the push plate 124. This not only improves the adaptability of the machine to the knife type, but also completes the automatic feeding of the knife body, reduces the labor cost, and improves the working speed and efficiency of knife grinding.

[0034] A number of air compression ports are opened inside the knife placement shell 11. Two air outlet openings are opened on the left side of the knife placement shell 11. Two small pneumatic rods 112 are fixedly connected to the left air outlet openings of the knife placement shell 11.

By setting the pressure fixing plates 113, specifically, when the electric pneumatic rod 121 pushes the push plate 124, it will also push the pressure block 122. The rubber pneumatic plate 123 fixedly connected to the left side of the pressure block 122 generates pressure on the small pneumatic rod 112 by pushing air, causing the small pneumatic rod 112 to move. The bottom of the small pneumatic rod 112 pushes the pressure fixing plate 113 to fix the knife, so that the knife will not move randomly during the grinding process, improving the accuracy of knife grinding and preventing the situation of unqualified knife quality caused by the random movement of the knife.

[0035] The left output end of the electric pneumatic rod 121 is fixedly connected to a push plate 124. Pressure blocks 122 are respectively fixedly connected to the front and back sides of the push plate 124. A rubber pneumatic plate 123 is fixedly connected to the left side of the pressure block 122.

[0036] A fixed block is arranged on the left side of the grinding table 1. An intermittent motor 13 is fixedly connected to the top of the fixed block. The right output end of the intermittent motor 13 is fixedly connected to a connecting rod 131. A rotating shaft 132 is fixedly connected to the right side of the connecting rod 131. A crawler 133 is connected to the outer surface of the rotating shaft 132 in a transmission manner. A support plate 134 is arranged on the front side of the connecting rod 131.

[0037] On the left top of the knife sharpening table 1, there is a support frame 27 fixedly connected. On the back of the support frame 27, there is a second motor 2 fixedly connected. The output end of the second motor 2 is fixedly connected with a threaded rod 22. On the front of the support frame 27, there are two sliding rods 25 fixedly connected. The outer surfaces of the two sliding rods 25 are slidably connected with a knife sharpener 24. On the top of the knife sharpener 24, there is a knife sharpening motor 21 fixedly connected. On the top of the second motor 2, there is a telescopic signal transmission rod 26 fixedly connected. On the left side of the knife sharpening motor 21, there is a telescopic signal transmission rod 26 fixedly connected. The output end of the knife sharpening motor 21 is fixedly connected with a grinding stone 23.

[0038] On the right side of the knife placement shell 11, there is an adjustment opening. At the bottom right of the knife placement shell 11, there is an opening. The internal air compression opening of the knife placement shell 11 is slidably connected with a pressure block 122. The opening at the bottom right of the knife placement shell 11 is slidably connected with a push plate 124.

[0039] On the right side of the second motor 2, it is fixedly connected with a fixed signal transmission rod 125. The knife sharpener 24 is in transmission connection with the threaded rod 22.

[0040] A specific application of this embodiment is:

[0041] In use, the user can place the outer shape fixing plate of knives of different models into the knife groove 111 according to their own needs, and then place the knife into the fixing plate. The knife is stacked in the knife groove 11 due to its own gravity. Start the first motor 12. The first motor 12 drives the push plate 124 and the pressure block 122 through the electric air pressure rod 121. The push plate 124 pushes the knife, and the knife falls onto the crawler 133 through the knife outlet opened on the left side of the knife housing 11. Due to the support plate 134 arranged inside the crawler 133, the knife will not move randomly due to the elasticity of the crawler 133. While the electric air pressure rod 121 drives the push plate 124, the push plate 124 drives the pressure block 122 to move. The pressure block 122 pushes the rubber air pressure plate 123 into the air compression port opened inside the knife housing 11. When the pressure block 122 moves, the rubber air pressure plate 123 pushes the air in the groove, squeezing the air. The squeezed air will rush towards the air outlet opened on the left side of the knife housing 11 to make the small air pressure rod 112 work. The small air pressure rod 112 drives the pressure fixing plate 113 to move downward to squeeze the knife body to play a fixing role. After the first motor 12 finishes working, it will stop working. The first motor 12 will transmit a signal to the second motor 2 through the fixed signal transmission rod 125. The second motor 2 starts to work. When the second motor 2 works, it will transmit a signal to the grinding motor 21 through the telescopic signal transmission rod 26. The grinding motor 21 works simultaneously with the work of the second motor 2. The grinding motor 21 drives the grinding stone 23 to move. The second motor 2 drives the threaded rod 22 to rotate. The threaded rod 22 drives the grinder 24 to move horizontally on the sliding rod 25 to grind the fixed knife. After the knife is ground, the second motor 2 will stop working. The second motor 2 transmits a signal to the first motor 12 through the fixed signal transmission rod 125 and works reciprocally. Due to the intermittent working characteristic of the intermittent motor 13, it will not work during grinding and will start to work after a certain period of time, that is, after the knife is ground. The intermittent motor 13 drives the rotating shaft 132 to rotate through the connecting rod 131. The rotating shaft 132 drives the crawler 133 to work to transport the ground knife out of the machine.
