Description

Technical Field

[0001] The utility model relates to the technical field of servo feeding machines, especially to servo feeding machines. Background Art

[0002] A servo feeding machine is a device widely used in the field of industrial automation. It combines the high-precision control technology of a servo motor and the mechanical transmission system of a feeding machine to achieve precise, efficient, and automated conveyance of materials such as metal plates, plastic films, and papers.

[0003] For example, a servo feeding machine with the publication number CN107377797A includes a machine table, a feeding roller arranged on the machine table, a servo feeding device for driving the feeding roller to rotate and feed, a pressure roller arranged opposite to the feeding roller, a release device for driving the pressure roller to press the material tightly against the feeding roller, and a material thickness adjusting device for adjusting the feeding gap between the pressure roller and the feeding roller. The pressure roller is installed on the release device, and the material thickness adjusting device is connected to the release device. The structure of the present invention is reasonably designed, with a fast feeding speed, high working efficiency, convenient control of the tightness state of the plate, high feeding precision, no indentation on the plate, ensuring the quality of the plate after feeding, and reducing the production cost.

[0004] In the existing servo feeding machines, the conveyance of materials is generally carried out by driving rollers. This makes the device often only capable of conveying materials with a relatively long length. Furthermore, the conveyance length of the materials is controlled by the number of rotations of the driving rollers. Since it is difficult to accurately calculate the outer diameter of the driving rollers, there will inevitably be a certain degree of deviation when the device conveys materials. Cumulatively, a relatively large deviation may occur in the end, affecting the processing operation of the materials. Content of the Utility Model

[0005] The purpose of the utility model is to provide a servo feeding machine to facilitate the solution of the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A servo feeding machine includes a bottom plate. Above the bottom plate, there is a material pushing component. Inside the bottom plate and at the driving end of the material pushing component, there is a clamping mechanism jointly arranged.

[0007] The material pushing component includes a slideway. The slideway is fixedly installed above the bottom plate through a plurality of connecting rods. Inside the slideway, a slider is slidably installed. A threaded rod penetrates through the slider. Both ends of the threaded rod are inserted into the plate wall of the slideway and rotatably connected to the slideway. On the right side of the slideway, a servo driver is fixedly installed. The driving end of the servo driver is fixedly connected to the threaded rod. An adjusting mechanism is arranged on the slideway.

[0008] Preferably, the clamping mechanism includes an electric telescopic rod. The bottom end of the slider extends outside the slideway and is fixedly connected to the top end of the electric telescopic rod. The bottom end of the electric telescopic rod is fixedly provided with a pressing plate, and a rubber pad is fixedly installed on the bottom side of the pressing plate.

[0009] Preferably, a storage groove is formed in the top side of the bottom plate corresponding to the position of the pressing plate. Two driving rods are relatively rotatably installed in the storage groove. A conveyor belt is sleeved on the outer peripheral sides of the two driving rods. The front and rear sides of the conveyor belt are evenly connected to the inner wall of the storage groove, and the top side of the conveyor belt is coplanar with the top side of the bottom plate. The inner wall of the conveyor belt is in interference fit with the outer peripheral wall of the driving rod.

[0010] Preferably, a support plate is arranged between the two driving rods, and both the front and rear ends of the support plate are fixedly connected to the inner wall of the storage groove. The left and right sides of the support plate are respectively in contact with the outer peripheral walls of the two driving rods, and the top side of the support plate is in contact with the inner wall of the conveyor belt.

[0011] Preferably, the adjusting mechanism includes a positioning pin with a T-shaped cross-section. A plurality of square holes are formed in the top side of the slideway, and the distance between adjacent two square holes is equal.

[0014] The utility model has the following beneficial effects:

[0015] When the improved servo feeder is in use, the slider can reciprocally slide a specific length in the slideway to intermittently push the material to move a specific length of distance. Since the reciprocating movement distance of the slider in the slideway is fixed, the device will not cause dimensional deviation in pushing the material, which affects the processing operation of the material. And the reciprocating sliding distance of the slider in the slideway can be adjusted through the adjusting mechanism, so that the device can adapt to more processing requirements of the raw materials and expand the application range of the device.

Specific embodiments

[0024] In order to make the technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The present utility model provides a technical solution: Referring to Figure 1 - Figure 6 , a servo feeding machine disclosed by the present utility model includes a bottom plate 1, a material pushing assembly 2 is arranged above the bottom plate 1, and a clamping mechanism 3 is jointly arranged in the bottom plate 1 and the driving end of the material pushing assembly 2;

[0026] The material pushing assembly 2 includes a slideway 21, the slideway 21 is fixedly arranged above the bottom plate 1 through a plurality of connecting rods, a slider 22 is slidably arranged in the slideway 21, a threaded rod 23 is threadedly penetrated through the slider 22, and both ends of the threaded rod 23 are inserted into the plate wall of the slideway 21 and rotatably connected to the slideway 21. A servo driver 24 is fixedly arranged on the right side of the slideway 21, and the driving end of the servo driver 24 is fixedly connected to the threaded rod 23. An adjusting mechanism 25 is arranged on the slideway 21.

[0027] In this embodiment, when the improved servo feeder is in use, the operator places the material at the middle position on the bottom plate 1. Subsequently, the servo driver 24 drives the threaded rod 23 to rotate in the reverse direction. Due to the mutual contact between the slider 22 and the inner wall of the slideway 21, the reversely rotating threaded rod 23 pulls the slider 22 towards the adjusting mechanism 25. Due to the constraint and limit of the adjusting structure, the slider 22 moves reversely by a fixed distance. Subsequently, the clamping mechanism 3 operates to clamp and limit the material, so that the material and the slider 22 are connected as a whole. Then, the servo driver 24 drives the threaded rod 23 to rotate forward, pushing the slider 22 to move back to its original position, thereby driving the material to move synchronously by a specific length of distance. Then, the clamping mechanism 3 releases the connection between the material and the slider 22. At this time, the slider 22 can reciprocate in the slideway 21 as described above, thereby continuously pushing the material to move a specific distance in sequence. Since the reciprocating movement distance of the slider 22 in the slideway 21 is fixed, the device will not cause dimensional deviation in pushing the material, which will affect the processing operation of the material.

[0028] In a further preferred embodiment of the present invention, as Figure 1 and Figure 3 shown, the clamping mechanism 3 includes an electric telescopic rod 31. The bottom end of the slider 22 extends outside the slideway 21 and is fixedly connected to the top end of the electric telescopic rod 31. A pressing plate 32 is fixedly installed at the bottom end of the electric telescopic rod 31, and a rubber pad 33 is fixedly installed on the bottom side of the pressing plate 32;

[0029] In this embodiment, after the reverse movement of the slider 22 is completed, the servo driver 24 stops running. Subsequently, the electric telescopic rod 31 is started, pushing the pressing plate 32 downward, so that the rubber pad 33 is in close contact with the material, thereby generating a great frictional force between the pressing plate 32 and the material. At this time, since the roughness of the top side of the bottom plate 1 is much smaller than the roughness of the surface of the rubber pad 33, only a very small friction will be generated between the material and the bottom plate 1, and the material will not have a strong friction with the bottom plate 1, thereby avoiding wear on the surface of the material.

[0030] In a further preferred embodiment of the present invention, as Figure 1 and Figure 5 shown, a storage groove 34 is formed at the top side of the bottom plate 1 corresponding to the position of the pressing plate 32. Two driving rods 35 are rotatably installed relative to each other in the storage groove 34. A conveyor belt 36 is sleeved on the outer peripheral sides of the two driving rods 35. The front and rear sides of the conveyor belt 36 are in contact with the inner wall of the storage groove 34 evenly, and the top side of the conveyor belt 36 is coplanar with the top side of the bottom plate 1. The inner wall of the conveyor belt 36 is in interference fit with the outer peripheral wall of the driving rod 35;

[0031] In this embodiment, during the movement of the above-mentioned material, the conveyor belt 36 rotates synchronously around the driving rod 35, and the material will not have strong friction with the conveyor belt 36, thus avoiding the wear of the material surface. Moreover, when the material stops moving, the surface roughness of the conveyor belt 36 is relatively large. Due to the frictional forces between the material and the conveyor belt 36 and between the material and the bottom plate 1, the material that loses the external force push immediately stops moving.

[0032] In a further preferred embodiment of the present utility model, as Figure 5 shown, a support plate 37 is provided between the two driving rods 35, and both the front and rear ends of the support plate 37 are fixedly connected to the inner wall of the storage tank 34. The left and right sides of the support plate 37 are respectively in contact with the outer peripheral walls of the two driving rods 35, and the top side of the support plate 37 is in contact with the inner wall of the conveyor belt 36;

[0033] In this embodiment, when the rubber pad 33 abuts against the material, due to the support and limitation of the conveyor belt 36 by the support plate 37, the conveyor belt 36 always maintains a straight state.

[0034] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 4 shown, the adjusting mechanism 25 includes a positioning pin 252 with a T-shaped cross-section. A plurality of square holes 251 are opened on the top side of the slideway 21, and the distances between adjacent two square holes 251 are equal. The bottom of the positioning pin 252 slides through the corresponding square hole 251;

[0035] In this embodiment, when the improved servo feeder is in use, the operator pulls out the positioning pin 252 from the square hole 251, and then inserts the positioning pin 252 into the corresponding square hole 251 according to needs, thereby adjusting the reciprocating movement distance of the slider 22 in the slideway 21.

[0036] In a further preferred embodiment of the present utility model, as Figure 6 shown, a pressure sensor 253 is fixedly installed at the position corresponding to the slider 22 in the positioning pin 252, and the detection end of the pressure sensor 253 extends outside the positioning pin 252 and is slidably connected to the positioning pin 252. The outer ring edge of the detection end of the pressure sensor 253 is arranged in an arc shape;

[0037] In this embodiment, when the slider 22 moves in the reverse direction, due to the mutual abutment between the slider 22 and the positioning pin 252, the slider 22 only moves a specific length of distance. Moreover, during the process of the slider 22 and the positioning pin 252 being in mutual contact, a pressure can be applied to the pressure sensor 253. After the pressure sensor 253 detects the pressure, the servo driver 24 automatically stops running and synchronously starts the electric telescopic rod 31, without the need for other operations by the operator, and the automation degree of the device is high.

[0038] In a further preferred embodiment of the present utility model, as Figure 1 shown, two baffles 4 are fixedly installed on the top side of the bottom plate 1 by bolts, and the two baffles 4 are oppositely arranged on the front and rear sides of the storage groove 34;

[0039] In this embodiment, when the improved servo feeder is in use, the operator first unscrews the bolts on the baffle 4, and then adjusts the position of the baffle 4 on the bottom plate 1 according to the need, so as to adjust the distance between the two baffles 4 according to the material specifications. After the position of the baffle 4 is adjusted, the baffle 4 is fixed on the bottom plate 1 by bolts again, so as to restrict and limit the movement of the material on the bottom plate 1 and prevent the material from shifting in position when moving on the bottom plate 1, which affects the processing operation of the material.

[0040] Working principle: When the improved servo feeder is in use, the operator first unscrews the bolts on the baffle 4, and then adjusts the position of the baffle 4 on the bottom plate 1 according to the need, so as to adjust the distance between the two baffles 4 according to the material specifications. After the position of the baffle 4 is adjusted, the baffle 4 is fixed on the bottom plate 1 by bolts again;

[0041] After the position of the baffle 4 is adjusted as described above, the operator pulls out the positioning pin 252 from the square hole 251. When the pressure sensor 253 moves to the position of the square hole 251, due to the mutual contact between the opening edge of the square hole 251 and the arc surface of the detection end of the pressure sensor 253, the detection end of the pressure sensor 253 can be pressed into the positioning pin 252 along the outer ring edge of the detection end of the pressure sensor 253, so that the positioning pin 252 can be directly pulled out from the square hole 251. Then, according to the distance that the material needs to move, the positioning pin 252 is inserted into the corresponding square hole 251 until the pressure sensor 253 is moved into the slideway 21;

[0042] It should be noted that when replacing the position of the positioning pin 252 as described above, a pressure can be applied to the detection end of the pressure sensor 253, so as to test the pressure sensor 253 to a certain extent to ensure the normal use of the pressure sensor 253;

[0043] After the position adjustment of the above-mentioned positioning pin 252 and the baffle 4 is completed, the operator passes the material through the two baffles 4 and makes the end of the material coplanar with the discharging end of the bottom plate 1. Subsequently, the servo driver 24 drives the threaded rod 23 to rotate reversely. Due to the mutual contact between the slider 22 and the inner wall of the slideway 21, the reversely rotating threaded rod 23 pulls the slider 22 towards the positioning pin 252 and drives the electric telescopic rod 31 and the pressing plate 32 to move synchronously until the slider 22 contacts the positioning pin 252. And during the process of the slider 22 fitting with the positioning pin 252, a pressure can be applied to the pressure sensor 253. After the pressure sensor 253 detects the pressure, the servo driver 24 stops running. Subsequently, the electric telescopic rod 31 starts and pushes the pressing plate 32 downward, making the rubber pad 33 fit tightly with the material, thereby generating a great frictional force between the pressing plate 32 and the material;

[0044] It should be noted that when the above-mentioned rubber pad 33 contacts the material, due to the support and limitation of the support belt 36 by the support plate 37, the support belt 36 always remains straight;

[0045] After the above-mentioned rubber pad 33 fits tightly with the material, the servo driver 24 drives the threaded rod 23 to rotate forward, thereby pushing the slider 22 to move backward and reset. And due to the frictional force between the pressing plate 32 and the material, the material can be driven to move a corresponding distance synchronously;

[0046] It should be noted that during the movement of the above-mentioned material, the conveyor belt 36 rotates around the driving rod 35 synchronously, and the contact force between the material and the bottom plate 1 is too small, so the material will not have a strong friction with the bottom plate 1, thereby avoiding wear on the surface of the material;

[0047] According to the above, the slider 22 reciprocates in the chute, so as to automatically and continuously push the material on the bottom plate 1 to move intermittently for a specific length of distance.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
