Description

Technical Field

[0001] The invention relates to the technical field of transport and feeding, in particular to a transport and feeding device for printing large porcelain bowls. Background Art

[0002] PLC is an industrial automation control device, mainly used for automatic control, logical operation and real-time monitoring. Combined with the transport feeding device, it can effectively control the feeding speed and feeding rhythm during the transportation process. When printing the inner and outer walls of a large porcelain bowl, a conveyor belt is needed to bring the porcelain bowl to the printing area. The gripping position of the porcelain bowl is mostly at the bottom edge of the bowl, where the pressure is relatively small. However, in the above transmission process, sudden stops in printing and sudden starts in transmission often occur, which causes the porcelain bowl at the top of the conveyor belt to be subjected to an sudden stop or sudden centripetal force at this moment, and eventually the mouth of the porcelain bowl tilts, causing misalignment in subsequent printing. To address the above problems, the following solutions are proposed. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a large porcelain bowl printing conveying and feeding device, comprising a bracket, a driving rod is rotatably connected to the inner wall of the bracket, a conveyor belt is sleeved on the outer wall of the driving rod, a PLC controller is fixedly connected to the side wall of the bracket, and further comprises: A fixing mechanism, which is fixedly connected to the outer wall of the conveyor belt and is used to drive the device and the porcelain bowl on the top of the device to rotate; The clamping mechanism is fixedly connected to the outer wall of the fixing mechanism and is used for clamping the porcelain bowl on the top and absorbing external pressure at the same time; A pressure mechanism, which is fixedly connected to the top of the clamping mechanism and is used to seal the clamping mechanism; Before use, the bracket is first fixed at the desired position, and then the porcelain bowl is fixed on the top of the clamping mechanism. Finally, the motor outside the bracket drives the driving rod to rotate, and the driving rod drives the conveyor belt to rotate.

[0004] Preferably, the fixing mechanism comprises: An installation component, the installation component is fixedly connected to the outer wall of the conveyor belt through a support member; The support member includes a mounting belt fixedly connected to the outer wall of the conveyor belt, a plurality of fixing rods fixedly connected to the inner wall of the mounting belt, and a rotating plate 1 rotatably connected to the inner wall of the fixing rod. An auxiliary component, the auxiliary component is fixedly connected to the side wall of the sliding round rod through a pressure piece; The pressure-bearing member comprises a liquid square tube fixedly connected to an end of the rotating plate away from the fixed rod, a sliding plate is slidably connected to the inner wall of the liquid square tube, and a sliding round rod is fixedly connected to the side wall of the sliding plate; Among them, the inside of the liquid square tube is filled with liquid. When the conveyor belt generates a short-distance position, the generated potential energy will drive the liquid square tube to displace through the fixed rod.

[0005] Preferably, the clamping mechanism includes: A clamping component, which is rotatably connected to the top of the liquid square tube through a rotating member; The rotating member includes an inclined frame rotatably connected to the top of the liquid square tube, and a load-bearing square plate is rotatably connected to one end of the inclined frame away from the liquid square tube; A circulation component, which is rotatably connected to the side wall of the sliding plate through a limiting member; The limiting member includes an L-shaped through-hole groove opened on the side wall of the sliding plate, and a rotating plate three is rotatably connected to the side wall of the L-shaped through-hole groove; Among them, when the external potential energy drives the sliding plate to slide along the inner wall of the liquid square tube through the sliding round rod, when the sliding plate moves outward, the rotating plate three rotates, increasing the hole diameter of the L-shaped through-hole groove, and when the sliding plate resets, the rotating plate three resets, reducing the hole diameter of the L-shaped through-hole groove.

[0006] Preferably, the pressure mechanism includes: A release component, which is fixedly connected to the side wall of the sliding plate through a contact member; The contact member includes a fixed bracket fixedly connected to the side wall of the sliding plate, a rotating bracket is rotatably connected to the inner wall of the fixed bracket, a push rod two is rotatably connected to the side wall of the rotating plate three, and one end of the push rod two away from the rotating plate three is rotatably connected to the inner wall of the fixed bracket; A buckle component, which is slidably connected to an L-shaped rod on the inner wall of the liquid square tube, a spring three is fixedly connected to the bottom of the L-shaped rod, and a spring four is fixedly connected to the inner wall of the bottom of the L-shaped rod; Among them, when the conveyor belt slides, the L-shaped rod will contact the outside of the installation component and force the buckle component to form a buckling state with the sliding plate, restricting the displacement of the sliding plate.

[0007] Preferably, the installation component includes a limiting plate fixedly connected to the inner wall of the bracket; Among them, there is a downward convex position at the center of the limiting plate, and this convex position is located at the center of the printing area, which enables the driving rod to control the buckle component to buckle the sliding plate and restrict the displacement of the sliding plate when printing.

[0008] Preferably, the auxiliary component includes a metal block fixedly connected to one end of the sliding round rod away from the sliding plate; Among them, when the conveyor belt suddenly starts to transport, due to its own weight, the metal block will drive the sliding plate to displace through the sliding round rod.

[0009] Preferably, the clamping assembly includes a clamping frame slidably connected to the top of the load-bearing square plate. A Y-shaped frame is rotatably connected to one end of the load-bearing square plate away from the inclined frame. The end of the Y-shaped frame away from the load-bearing square plate is fixedly connected to the top of the metal block; Among them, the porcelain bowl is clamped and fixed to the top of the clamping frame. When the distance between the metal block and the liquid square tube increases due to its own potential energy, the inclined frame will rotate and change the pressure position of the porcelain bowl.

[0010] Preferably, the circulation assembly includes a torsion spring fixedly connected to the outer wall of the sliding plate. The end of the torsion spring away from the fixed rod is fixedly connected to the inner wall of the third rotating plate; Among them, when the third rotating plate rotates, the torsion spring will deform and provide power for subsequent reset. And the L-shaped through hole groove is a right-angle groove, which makes the third rotating plate can only rotate in one direction.

[0011] Preferably, the release assembly includes a limiting rod fixedly connected to the inner wall of the liquid square tube, and a second spring is fixedly connected to the side wall of the sliding plate; Among them, during the displacement of the sliding plate, the second spring is stretched to continue its potential energy, and when it is reset later, it drives the sliding plate to reset.

[0012] Preferably, the buckle assembly includes an inclined plane rod slidably connected to the inner wall of the L-shaped rod, and a groove is formed in the top of the sliding plate; Among them, when the L-shaped rod drives the inclined plane rod to slide downward, the inclined plane rod will exceed the bottom of the liquid square tube. And at this time, as the sliding plate slowly resets, the sliding plate will squeeze the inclined plane rod to slide upward and buckle on the inner wall of the groove, restricting the displacement of the sliding plate.

[0013] The present invention has the following beneficial effects: (1) In view of the problem that the displacement of the conveyor belt may cause the offset of the porcelain bowl, a metal block is arranged inside the device. Due to the large weight of the metal block, a relatively large pulling force is required, and the metal block will have a certain lag. This lag will be transmitted to the sliding plate through the sliding round rod, causing the sliding plate to displace along the inner wall of the liquid square tube towards the metal block. During this process, as Figure 4 、 5 , when the sliding plate displaces towards the metal block, the third rotating plate will rotate, presenting the state of T as shown in Figure 4 . As the third rotating plate rotates, the distance between the two third rotating plates increases, making the flow rate of the sliding plate inside the hole faster. At this time, the sliding efficiency of the sliding plate along the inner wall of the liquid square tube is accelerated, and at this time, the second spring is compressed and extended, slowing down the outward movement speed of the sliding plate and the metal block. While the speed of the metal block slows down, the moving speed of the porcelain bowl at the top of the clamping assembly will also slow down. Through the application of the above components, during the use of the device, the pressure on the porcelain bowl in the early stage of movement can be effectively reduced; (2) After the second spring is compressed and released, the closer it gets to the limiting rod, the smaller the released pressure. A release component is provided inside the device. After the device completes a single displacement, the sliding plate is pulled down by the second spring to reset. At this time, the third rotating plate will block the L-shaped through-hole groove to reduce the diameter of the flow port, presenting a state as shown in Figure 5 . This causes the displacement speed of the sliding plate to decrease, avoiding too fast a reset speed and causing the porcelain bowl at the top of the clamping bracket to shift; (3) During the sliding process of the sliding plate, the end of the limiting rod will contact the side wall of the rotating bracket and force the rotating bracket to rotate around the fixed bracket. The second push rod drives the third rotating plate to open outward again. At this time, the pressure released by the second spring has reached the critical point. Through the application of the above components, the reset efficiency of the porcelain bowl is increased; (4) Taking advantage of the characteristic that the distance between the metal block and the liquid square tube decreases during the above operation process, a clamping component is provided inside the device. Among them, when the device is in operation, the distance between the metal block and the liquid square tube is stable, making the clamping bracket in a horizontal state, presenting a state as shown in Figure 4 . As the distance between the two increases, the metal block will drive the Y-shaped frame away from the load-bearing square plate. At this time, the load-bearing square plate and the clamping bracket at the top will present a state as shown in Figure 7 G in. The above components first deform and then drive the metal block to displace. This converts the horizontal bearing force of the porcelain bowl into an oblique downward pressure towards the clamping bracket direction, increasing the clamping force of the clamping bracket on the rim of the porcelain bowl and effectively preventing the bowl from shifting due to excessive horizontal pressure; (5) Taking advantage of the characteristic that the above conveyor belt drives the liquid square tube to displace, a buckle component is provided inside the device. Among them, there is a downward protrusion at the center position of the limiting plate, and this protrusion is located at the center of the printing area. This enables when printing, when the driving rod forces the L-shaped rod to drive the inclined rod to slide downward, the inclined rod will exceed the bottom of the liquid square tube. At this time, as the sliding plate slowly resets, the sliding plate will squeeze the inclined surface of the inclined rod, causing the inclined rod to slide upward and finally buckle on the inner wall of the groove, restricting the displacement of the sliding plate towards the metal block direction. After the device transports the porcelain bowl to the printing position, the Y-shaped frame and the inclined frame can withstand the downward extrusion pressure from the top, preventing the inclined frame from rotating and affecting the printing quality.

[0018] Embodiment 1. Please refer to Figures 1 - 7 , the present invention is a transportation and feeding device for printing large porcelain bowls, including a bracket 13.

Subsequently, fix the porcelain bowl on the top of the clamping mechanism 2. Finally, the motor outside the bracket 13 drives the driving rod 14 to rotate, and the driving rod 14 drives the transmission belt 15 to rotate.

[0019] The fixing mechanism 1 includes: An installation component 11, which is fixedly connected to the outer wall of the transmission belt 15 through a support member; The support member includes an installation belt 111 fixedly connected to the outer wall of the transmission belt 15. A plurality of fixing rods 112 are fixedly connected to the inner wall of the installation belt 111. A rotating plate 113 is rotatably connected to the inner wall of the fixing rod 112. An auxiliary component 12, which is fixedly connected to the side wall of the sliding round rod 123 through a pressure-receiving member; The pressure-receiving member includes a liquid square tube 121 fixedly connected to one end of the rotating plate 113 away from the fixing rod 112. A sliding plate 122 is slidably connected to the inner wall of the liquid square tube 121. A sliding round rod 123 is fixedly connected to the side wall of the sliding plate 122; Among them, the inside of the liquid square tube 121 is filled with liquid. When the transmission belt 15 generates a short-distance position, the generated potential energy will drive the liquid square tube 121 to generate displacement through the fixing rod 112.

[0020] The clamping mechanism 2 includes: A clamping component 21, which is rotatably connected to the top of the liquid square tube 121 through a rotating member; The rotating member includes an inclined frame 214 rotatably connected to the top of the liquid square pipe 121, and a load-bearing square plate 212 is rotatably connected to one end of the inclined frame 214 away from the liquid square pipe 121; The circulation component 22 is rotatably connected to the side wall of the sliding plate 122 through a limiting member; The limiting member includes an L-shaped through hole groove 221 formed in the side wall of the sliding plate 122, and a rotating plate three 222 is rotatably connected to the side wall of the L-shaped through hole groove 221; Among them, when the external potential energy drives the sliding plate 122 to slide along the inner wall of the liquid square pipe 121 through the sliding round rod 123, when the sliding plate 122 moves outward, the rotating plate three 222 rotates, increasing the hole diameter of the L-shaped through hole groove 221, and when the sliding plate 122 resets, the rotating plate three 222 resets, reducing the hole diameter of the L-shaped through hole groove 221.

[0021] The pressure mechanism 3 includes: The release component 31 is fixedly connected to the side wall of the sliding plate 122 through a contact member; The contact member includes a fixed bracket 311 fixedly connected to the side wall of the sliding plate 122. A rotating bracket 312 is rotatably connected to the inner wall of the fixed bracket 311. A push rod two 313 is rotatably connected to the side wall of the rotating plate three 222. One end of the push rod two 313 away from the rotating plate three 222 is rotatably connected to the inner wall of the fixed bracket 311; The buckle component 32 is slidably connected to an L-shaped rod 321 on the inner wall of the liquid square pipe 121. A spring three 322 is fixedly connected to the bottom of the L-shaped rod 321, and a spring four 323 is fixedly connected to the inner wall of the bottom of the L-shaped rod 321; Among them, when the conveyor belt 15 slides, the L-shaped rod 321 will contact the outside of the installation component 11 and force the buckle component 32 to form a buckling state with the sliding plate 122, restricting the displacement of the sliding plate 122.

[0022] Example two, please refer to Figures 2 - 11 , The present invention is a transportation and feeding device for printing large porcelain bowls. On the basis of Example 1, the installation component 11 includes a limiting plate 114 fixedly connected to the inner wall of the bracket 13; Among them, there is a downward convex position at the center of the limiting plate 114, and this convex position is located at the center of the printing area, which enables the driving rod 14 to control the buckle component 32 to buckle the sliding plate 122 and restrict the displacement of the sliding plate 122 during printing; During the above operation process, taking advantage of the characteristic that the distance between the metal block 124 and the liquid square tube 121 decreases, the clamping component 21 is clamped inside the device. Among them, when the device is in the operating state, the distance between the metal block 124 and the liquid square tube 121 is stable, making the clamping frame 213 in a horizontal state, presenting as Figure 4 In the state of, and as the distance between the two increases, the metal block 124 will drive the Y-shaped frame 211 away from the load-bearing square plate 212. At this time, the load-bearing square plate 212 and the clamping frame 213 at the top will present as Figure 7 In the state of G in, and the above components first deform and then drive the metal block 124 to generate displacement. This transforms the horizontal bearing force of the porcelain bowl into an oblique downward pressure in the direction of the clamping frame 213, increasing the clamping force of the clamping frame 213 on the rim of the porcelain bowl, effectively preventing the bowl from shifting due to excessive horizontal pressure.

[0023] The auxiliary component 12 includes a metal block 124 fixedly connected to the end of the sliding round rod 123 away from the sliding plate 122; During the rotation of the conveyor belt 15, it will drive the installation belt 111 and the fixed rod 112 to run synchronously. When the device starts suddenly, the installation belt 111 will drive the liquid square tube 121 to generate a synchronous displacement through the rotating plate 113 of the fixed rod 112. During this process, due to the large self-weight of the metal block 124, a relatively large pulling force is required, and the metal block 124 will have a certain lag. This lag will be transmitted to the sliding plate 122 through the sliding round rod 123, causing the sliding plate 122 to displace along the inner wall of the liquid square tube 121 towards the direction of the metal block 124; Among them, when the conveyor belt 15 starts suddenly, due to its own weight, the metal block 124 will drive the sliding plate 122 to generate displacement through the sliding round rod 123.

[0024] The clamping component 21 includes a clamping frame 213 slidably connected to the top of the load-bearing square plate 212. One end of the load-bearing square plate 212 away from the inclined frame 214 is rotatably connected to a Y-shaped frame 211. The end of the Y-shaped frame 211 away from the load-bearing square plate 212 is fixedly connected to the top of the metal block 124; Among them, the limiting block 215 will limit the rotation angle of the inclined frame 214 to ensure that the angle between the inclined frame 214 and the load-bearing square plate 212 does not exceed 170 degrees. When the liquid square tube 121 and the metal block 124 are reset, the load-bearing square plate 212 can be in a horizontal state again; Such as Figure 4 、 5 , when the sliding plate 122 displaces towards the metal block 124, the rotating plate 222 will rotate, presenting as Figure 4The state of T in the middle. As the rotating plate three 222 rotates, the distance between the two rotating plates three 222 expands, causing the sliding plate 122 to flow faster inside the hole. At this time, the sliding efficiency of the sliding plate 122 along the inner wall of the liquid square tube 121 increases. And at this time, the release component 31 extends and slows down the outward movement speed of the sliding plate 122 and the metal block 124. While the speed of the metal block 124 slows down, the moving speed of the porcelain bowl at the top of the clamping component 21 will slow down. Through the application of the above components, during the use of the device, the pressure on the porcelain bowl in the early stage of movement is effectively reduced; Among them, the porcelain bowl is clamped and fixed at the top of the clamping frame 213. When the distance between the metal block 124 and the liquid square tube 121 increases due to its own potential energy, the inclined frame 214 will rotate and change the pressure position of the porcelain bowl.

[0025] The circulation component 22 includes a torsion spring 223 fixedly connected to the outer wall of the sliding plate 122. One end of the torsion spring 223 away from the fixed rod 112 is fixedly connected to the inner wall of the rotating plate three 222; Among them, when the rotating plate three 222 rotates, the torsion spring 223 will deform and provide power for subsequent reset. And the L-shaped through-hole groove 221 is a right-angle groove, which makes the rotating plate three 222 can only rotate in one direction. During the sliding process of the sliding plate 122, the end of the limiting rod 314 will contact the side wall of the rotating bracket 312 and force the rotating bracket 312 to rotate around the fixed bracket 311, and drive the rotating plate three 222 to open outward again through the push rod two 313. And at this time, the pressure released by the release component 31 has reached the critical point. Through the application of the above components, the reset efficiency of the porcelain bowl is accelerated; The release component 31 includes a limiting rod 314 fixedly connected to the inner wall of the liquid square tube 121, and a spring two 315 is fixedly connected to the side wall of the sliding plate 122; Using the fact that after the spring two 315 is compressed and released, the closer it is to the limiting rod 314, the smaller the released pressure. The release component 31 is arranged inside the device. After the device completes a single displacement, at this time, the sliding plate 122 is pulled by the spring two 315 to reset, and at this time, the rotating plate three 222 will block the L-shaped through-hole groove 221 to reduce the diameter of the circulation port, presenting a state as shown in Figure 5 This makes the displacement speed of the sliding plate 122 decrease, avoiding the porcelain bowl at the top of the clamping frame 213 from shifting due to too fast a reset speed; Among them, during the displacement process of the sliding plate 122, the spring two 315 is stretched to store potential energy and drive the sliding plate 122 to reset during subsequent reset.

[0026] The buckle component 32 includes an inclined plane rod 324 slidably connected to the inner wall of the L-shaped rod 321, and a groove 325 is opened at the top of the sliding plate 122; When the L-shaped rod 321 drives the inclined plane rod 324 to slide downward, the inclined plane rod 324 will exceed the bottom of the liquid square tube 121. At this time, as the sliding plate 122 slowly resets, the sliding plate 122 will squeeze the inclined plane rod 324 to slide upward and snap onto the inner wall of the groove 325, restricting the displacement of the sliding plate 122. Taking advantage of the characteristic that the above-mentioned conveyor belt 15 drives the liquid square tube 121 to generate displacement, a snap component 32 is provided inside the device. Among them, there is a downward protrusion at the center position of the limiting plate 114, and this protrusion is located at the center of the printing area. This enables when printing, when the driving rod 14 forces the L-shaped rod 321 to drive the inclined plane rod 324 to slide downward, the inclined plane rod 324 will exceed the bottom of the liquid square tube 121. At this time, as the sliding plate 122 slowly resets, the sliding plate 122 will squeeze the inclined plane of the inclined plane rod 324, causing the inclined plane rod 324 to slide upward and finally snap onto the inner wall of the groove 325, restricting the displacement of the sliding plate 122 in the direction of the metal block 124. After the device runs the porcelain bowl to the printing position, the Y-shaped frame 211 and the inclined frame 214 can withstand the downward extrusion pressure at the top, avoiding the inclined frame 214 from rotating and affecting the printing quality.

[0027] A specific application of this embodiment is as follows: Before using the present invention, first fix the bracket 13 at the required position, then fix and clamp the porcelain bowl on the top of the clamping frame 213, and finally drive the driving rod 14 and the conveyor belt 15 to rotate through the motor outside the bracket 13. During the rotation of the conveyor belt 15, it will drive the installation belt 111 and the fixed rod 112 to run synchronously. When the device starts suddenly, the installation belt 111 will drive the liquid square tube 121 to generate the same-speed displacement through the fixed rod 112 and the rotating plate one 113. During this process, due to the large self-weight of the metal block 124, a relatively large pulling force is required, and the metal block 124 will have a certain lag. This lag will be transmitted to the sliding plate 122 through the sliding round rod 123, causing the sliding plate 122 to displace along the inner wall of the liquid square tube 121 in the direction of the metal block 124. During this process, as Figure 4 、 5 , when the sliding plate 122 displaces in the direction of the metal block 124, the rotating plate three 222 will rotate, presenting as Figure 4The state of T in the middle. As the rotating plate three 222 rotates, the distance between the two rotating plates three 222 increases, causing the sliding plate 122 to flow faster inside the hole. At this time, the sliding efficiency of the sliding plate 122 along the inner wall of the liquid square tube 121 increases. At the same time, the spring two 315 is compressed and extended, slowing down the outward movement speed of the sliding plate 122 and the metal block 124. While the speed of the metal block 124 slows down, the moving speed of the porcelain bowl at the top of the clamping component 21 will slow down. Through the application of the above components, during the use of the device, the pressure on the porcelain bowl in the early stage of movement is effectively reduced; Using the fact that the closer the spring two 315 is to the limiting rod 314 after being compressed and released, the smaller the released pressure. A release component 31 is provided inside the device. After the device completes a single displacement, at this time, the sliding plate 122 is pulled down by the spring two 315 to reset. And at this time, the rotating plate three 222 will block the L-shaped through-hole groove 221 to reduce the diameter of the flow port, presenting a state like Figure 5 This state causes the displacement speed of the sliding plate 122 to decrease, avoiding the porcelain bowl at the top of the clamping bracket 213 from shifting due to too fast a reset speed. In addition, during the sliding of the sliding plate 122, the end of the limiting rod 314 will contact the side wall of the rotating bracket 312, forcing the rotating bracket 312 to rotate around the fixed bracket 311, and driving the rotating plate three 222 to open outward again through the push rod two 313. At this time, the pressure released by the spring two 315 has reached the critical point. Through the application of the above components, the reset efficiency of the porcelain bowl is increased; Using the characteristic that the distance between the metal block 124 and the liquid square tube 121 decreases during the above operation process, a clamping component 21 is provided inside the device. Among them, when the device is in an operating state, the distance between the metal block 124 and the liquid square tube 121 is stable, making the clamping bracket 213 in a horizontal state, presenting a state like Figure 4 As the distance between the two increases, the metal block 124 will drive the Y-shaped frame 211 away from the load-bearing square plate 212. At this time, the load-bearing square plate 212 and the clamping bracket 213 at the top will present a state like Figure 7 in G. And the above components first deform and then drive the metal block 124 to generate displacement. This transforms the horizontal bearing force of the porcelain bowl into an oblique downward pressure towards the clamping bracket 213 direction, increasing the clamping force of the clamping bracket 213 on the rim of the porcelain bowl, effectively preventing the bowl from shifting due to excessive horizontal pressure; Taking advantage of the feature that the above-mentioned conveyor belt 15 drives the liquid square tube 121 to generate displacement, a buckle assembly 32 is provided inside the device. Among them, there is a downward protrusion at the center position of the limiting plate 114, and this protrusion is located at the center of the printing area. This enables, when printing, that when the driving rod 14 forces the L-shaped rod 321 to drive the inclined surface rod 324 to slide downward, the inclined surface rod 324 will exceed the bottom of the liquid square tube 121. And at this time, as the sliding plate 122 slowly resets, the sliding plate 122 will squeeze the inclined surface of the inclined surface rod 324, causing the inclined surface rod 324 to slide upward and finally buckle on the inner wall of the groove 325, restricting the displacement of the sliding plate 122 in the direction of the metal block 124. So that after the device runs the porcelain bowl to the printing position, the Y-shaped frame 211 and the inclined frame 214 can withstand the pressure of being squeezed downward from the top, preventing the inclined frame 214 from rotating and affecting the printing quality.
