[0002] Rubber lining is a lining layer of wear-resistant, corrosion-resistant and high-temperature-resistant rubber used inside equipment or pipelines. The physical and chemical properties of rubber itself reduce the impact of pipeline conveying media on the external structure, such as impact force and corrosion.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1.

[0019] 3. In the present invention, when a positioning pressure plate that contacts the upper surface of the rubber lining moves to the right end of the device, the ball corresponding to the positioning pressure plate just rolls along the bottom of the horizontal plane of the guide rail to the curved surface position at the rightmost end of the guide rail. At this time, the rebound force of the reset spring is released, pushing the positioning rod, the positioning pressure plate, the ball cage seat and the ball upward to reset, so that the bottom of the positioning pressure plate is separated from the upper surface of the rubber lining, which is convenient for material removal, so that the rubber lining can be fed from the rightmost end of the device.

[0020] 4. In the present invention, by rotating the hand wheel in the adjustment assembly, the height of the front and rear guide rails can be adjusted, thereby controlling the downward pressure distance of the ball, that is, adjusting the downward movement distance of the positioning pressure plate, so as to be suitable for the feeding service of rubber linings of different thicknesses, thereby improving the universality and flexibility of the device.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 9 The technical solution provided by the present invention specifically includes the following embodiments:

[0033] Embodiment 1: A fully automatic feeding system for rubber lining, comprising a conveying frame 100, a positioning assembly 200 and an adjusting assembly 300, wherein the conveying frame 100 is provided with two front and rear conveying frames, a positioning assembly 200 is provided between the two conveying frames 100, an adjusting assembly 300 is provided on the top of the two conveying frames 100, the positioning assembly 200 comprises two left and right distributed positioning shafts 201, the two positioning shafts 201 are rotatably installed between the front and rear conveying frames 100, the outer walls of the two positioning shafts 201 are fixedly installed with two front and rear distributed positioning synchronous wheels 202, wherein the outer peripheries of the two left and right positioning synchronous wheels 202 are both sleeved together There are two positioning synchronous belts 203, one at the front and one at the back. A plurality of positioning seats 204 distributed at equal distances are fixedly installed on the periphery of the two positioning synchronous belts 203. A telescopic hole 205 is penetrated through the side of the positioning seat 204 close to the positioning synchronous belt 203. A positioning rod 206 is slidably installed inside the telescopic hole 205. The angle between the telescopic hole 205 and the positioning seat 204 is 5 degrees. A positioning pressure plate 207 is fixedly installed on one end of the positioning rod 206 close to the positioning synchronous belt 203. The positioning assembly 200 also includes two front and rear guide rails 2011, and the two guide rails 2011 are located between the two front and rear positioning synchronous belts 203.

[0034] A ball cage seat 208 is fixedly mounted on one end of the positioning rod 206 away from the positioning pressure plate 207, and a ball 209 is rotatably mounted inside the ball cage of the ball cage seat 208. The bottom of the guide rail 2011 abuts against the top of the ball 209 located at the bottom layer, and the two ends of the guide rail 2011 are arranged in an upward curved shape;

[0035] Two conveying shafts 101 distributed left and right are rotatably installed between the front and rear conveying frames 100, and multiple conveying wheels 102 distributed at equal distances front and back are fixedly installed on the outer walls of the two conveying shafts 101, wherein the outer peripheries of the two conveying wheels 102 in the left and right directions are jointly sleeved with a conveying belt 103, and there are multiple conveying belts 103 in total, wherein the frontmost and rearmost conveying belts 103 correspond to the positions of the positioning pressing plates 207 at the front and rear positions respectively;

[0036] An aluminum profile frame 700 is fixedly installed at the bottom of the front and rear conveying frames 100, a reduction motor 400 is fixedly installed at the left end of the aluminum profile frame 700, and a driving sprocket 401 is fixedly installed on the output shaft of the reduction motor 400, wherein a primary driven sprocket 402 is fixedly installed at the end of the conveying shaft 101 located at the left part of the conveying frame 100, and a secondary driven sprocket 403 is fixedly installed at the end of the positioning shaft 201 located at the left part of the conveying frame 100, and a power chain 404 is sleeved on the periphery of the driving sprocket 401, the primary driven sprocket 402 and the secondary driven sprocket 403, and the primary driven sprocket 402 is externally meshed with the power chain 404, and the driving sprocket 401 and the secondary driven sprocket 403 are internally meshed with the power chain 404;

[0037] Specifically, the left end of the device is connected to the output end of the previous process of the rubber lining production equipment. After the rubber lining processed in the previous process is transported to the left end of the device, the output shaft of the reduction motor 400 drives the driving sprocket 401 to rotate clockwise. The driving sprocket 401 rotates further under the connection of the power chain 404, driving the primary driven sprocket 402 and the secondary driven sprocket 403 to rotate. Since the power chain 404 and the primary driven sprocket 402 are externally meshed, The power chain 404 and the secondary driven sprocket 403 are internally meshed, so the primary driven sprocket 402 and the secondary driven sprocket 403 rotate in opposite directions, that is, the primary driven sprocket 402 in the device rotates clockwise, while the secondary driven sprocket 403 rotates counterclockwise. The clockwise rotation of the primary driven sprocket 402 drives the conveying wheel 102 to rotate through the connection of the conveying shaft 101, so that the conveyor belt 103 rotates around the left and right conveying wheels 102, and the rubber lining is fed to the right end of the device;

[0038] The model of the aluminum profile frame 700 of the device is not fixed, and can be selected according to the requirements of use. In other words, the height and level of the aluminum profile frame 700 can be adjusted. Specifically, when there is a deviation in the left and right heights of the feeding, that is, when the rubber lining is fed from the lower end to the higher end, the device can also avoid the problem of slipping between the rubber lining and the top of the conveyor belt 103. Specifically, the secondary driven sprocket 403 rotates counterclockwise through the positioning shaft 201 to drive the positioning synchronous wheel 202 to rotate together , further making the front and rear two positioning synchronous belts 203 rotate around the positioning synchronous wheel 202 in the left and right directions, the positioning synchronous belt 203 rotates through the positioning seat 204 to drive the positioning rod 206, the positioning pressure plate 207, etc. to move together, when the positioning pressure plate 207 moves to the bottom of the center of a positioning synchronous wheel 202 at the left end along with the positioning synchronous belt 203, the ball 209 corresponding to the positioning pressure plate 207 is just located at the left end curved surface position of the guide rail 2011, and then the positioning synchronous belt 203 drives the positioning pressure plate 207 The ball 209 moves to the right, causing the ball 209 to move downward along the left end curved surface of the guide rail 2011 until the ball 209 moves to the bottom horizontal section of the guide rail 2011. During this period, the ball 209 moves downward and presses the positioning rod 206 downward through the ball cage seat 208, causing the positioning rod 206 to move downward along the inner wall of the telescopic hole 205, and pushes the positioning pressure plate 207 to move downward together, against the upper surface of the rubber lining at the top of the conveyor belt 103, and moves to the right together with the rubber lining. The contact friction between the bottom 7 and the upper surface of the rubber lining can avoid the rubber lining from slipping on the top of the conveyor belt 103 during the feeding process, thereby ensuring the stability of the rubber lining feeding. It should be noted that the angle between the telescopic hole 205 and the positioning seat 204 of the device is 5 degrees, that is, the positioning rod 206 actually moves obliquely downward. Therefore, during the downward movement of the positioning rod 206 in the front-to-back direction, it also has the effect of stretching the rubber lining in the front-to-back direction, thereby eliminating the front-to-back wrinkles of the rubber lining.

[0039] Furthermore, a return spring 2010 is provided on the outer sleeve of the positioning rod 206, and the return spring 2010 is fixedly installed between the positioning seat 204 and the positioning pressure plate 207;

[0040] As the positioning pressure plate 207 moves downward, the reset spring 2010 will be pulled up and accumulated force, thereby providing elastic potential energy for the positioning rod 206, the positioning pressure plate 207, the ball cage seat 208 and the ball 209 to reset upward. Therefore, when a positioning pressure plate 207 that contacts the upper surface of the rubber lining moves to the right end of the device, the ball 209 corresponding to the positioning pressure plate 207 just rolls along the bottom of the horizontal plane of the guide rail 2011 to the curved surface position at the rightmost end of the guide rail 2011. At this time, the rebound force of the reset spring 2010 is released, pushing the positioning rod 206, the positioning pressure plate 207, the ball cage seat 208 and the ball 209 upward to reset, so that the bottom of the positioning pressure plate 207 is separated from the upper surface of the rubber lining, which is convenient for material removal, so that the rubber lining can complete the feeding from the rightmost end of the device.

[0041] Embodiment 2: The adjustment component 300 includes an adjustment seat 301 fixedly mounted on the top of the two conveying frames 100, a hand wheel 302 is rotatably provided on the top of the adjustment seat 301, a screw rod 303 is fixedly mounted on the bottom of the hand wheel 302, the screw rod 303 movably passes through the top of the adjustment seat 301 and extends into the interior thereof, and the screw rod 303 is rotatably connected to the through hole of the adjustment seat 301 through a bearing, an inner thread tube 304 is spirally connected to the outer wall of the screw rod 303, an adjustment platform 305 is fixedly mounted on the bottom of the inner thread tube 304, the bottom of the adjustment platform 305 is fixedly connected to the top of the front and rear guide rails 2011, the bottom of the screw rod 303 passes through the interior of the adjustment platform 305, and the outer wall of the screw rod 303 and the inner wall of the through hole of the adjustment platform 305 are clearance-fitted;

[0042] The present embodiment is specifically that the downward pressing distance of the positioning pressing plate 207 in the present device can be adjusted according to the thickness of the rubber lining to be fed. Specifically, the screw rod 303 is driven to rotate by manually rotating the hand wheel 302, and the inner wire tube 304 is further moved upward or downward along the axial direction of the screw rod 303 under the threaded cooperation between the screw rod 303 and the inner wire tube 304. The movement of the inner wire tube 304 further drives the adjustment platform 305 to move upward or downward, and the upward or downward movement of the adjustment platform 305 further drives the front and rear guide rails 2011 to move together, so that the height of the front and rear guide rails 2011 is adjusted, thereby controlling The downward pressing distance of the ball 209, that is, the downward moving distance of the positioning pressure plate 207, is adjusted to be suitable for the feeding service of rubber linings of different thicknesses, thereby improving the universality and flexibility of the device. At the same time, since the bottom of the screw 303 passes through the adjusting platform 305, the up and down movement of the adjusting platform 305 will not interfere with the bottom of the screw 303, and a clearance is set between the outer wall of the screw 303 and the inner wall of the through hole of the adjusting platform 305, that is to say, during the rotation of the screw 303, its outer wall will not contact and rub with the inner wall of the through hole of the adjusting platform 305, thereby ensuring the smooth rotation of the screw 303.

[0043] Further, guide rods 306 are fixedly installed at the four corners of the top of the adjustment platform 305, and guide sleeves 307 are fixedly installed at the four corners of the top of the adjustment seat 301. The guide rods 306 movably penetrate the adjustment seat 301 and the interior of the guide sleeve 307, and the outer wall of the guide rod 306 is slidably connected to the inner wall of the guide sleeve 307;

[0044] The adjusting platform 305 is slidably connected with four guide rods 306 and four guide sleeves 307. On the one hand, it can prevent the adjusting platform 305 from rotating along the axial direction of the screw rod 303. On the other hand, the sliding connection between the four guide rods 306 and the four guide sleeves 307 can provide a precise guiding and positioning effect for the up and down movement of the adjusting platform 305, thereby ensuring the stability and smoothness of the up and down movement of the adjusting platform 305.

[0045] Embodiment 3: A plurality of supporting shafts 600 equidistantly distributed on the left and right are rotatably mounted between the front and rear conveying frames 100, and a plurality of belt-carrying rollers 601 distributed front and back are fixedly mounted on the outer walls of the supporting shafts 600. The number of belt-carrying rollers 601 distributed front and back corresponds to the number and position of conveying rollers 102 distributed front and back, and the top of the belt-carrying rollers 601 abuts against the top of the inner side surface of the conveying belt 103;

[0046] Specifically, in this embodiment, a support shaft 600 is provided to provide a rotation support effect for a belt support wheel 601, and a plurality of belt support wheels 601 are provided to provide a middle support effect for a conveyor belt 103, thereby preventing the conveyor belt 103 between the left and right conveyor wheels 102 from sagging, thereby ensuring the stability of feeding.

[0047] Embodiment 4: A metering sensor 500 is fixedly installed at the top rear end of the adjustment seat 301, the metering sensor 500 is located at the top of the rear positioning plate 207, and the output end of the metering sensor 500 is electrically connected to the input end of the external computer;

[0048] Specifically, the present embodiment monitors the number of positioning plates 207 passing through the bottom thereof by setting a metering sensor 500. Since the spacing between two adjacent positioning plates 207 in the present device is equal, the metering sensor 500 is used to monitor the change in the number of positioning plates 207 passing through the bottom thereof, and transmits a statistical signal to an external computer. The length of the rubber lining transported by the conveyor belt 103 can be obtained by calculation, thereby facilitating statistics on the specific transport volume of the feed.

[0049] In the present scheme, a fully automatic rubber lining feeding system is connected with the left end of the device to the output end of the previous process of the rubber lining production equipment when it is working. After the rubber lining processed in the previous process is delivered to the left end of the device, the output shaft of the reduction motor 400 drives the driving sprocket 401 to rotate clockwise. The driving sprocket 401 further rotates under the connection of the power chain 404, driving the primary driven sprocket 402 and the secondary driven sprocket 403 to rotate. The power chain 404 and the secondary driven sprocket 403 are externally meshed, while the power chain 404 and the secondary driven sprocket 403 are internally meshed, so the primary driven sprocket 402 and the secondary driven sprocket 403 rotate in opposite directions, that is, the primary driven sprocket 402 in the device rotates clockwise, while the secondary driven sprocket 403 rotates counterclockwise. The clockwise rotation of the primary driven sprocket 402 drives the conveying wheel 102 to rotate through the connection of the conveying shaft 101, so that the conveying belt 103 rotates around the left and right conveying wheels 102, and the rubber lining is fed to the right end of the device;

[0050] It should be noted here that the model of the aluminum profile frame 700 of the device is not fixed, and an adaptive selection can be made according to the requirements of use. In other words, the height and levelness of the aluminum profile frame 700 can be adjusted. Specifically, when there is a deviation in the left and right heights of the feeding, that is, when the rubber lining is fed from the lower end to the higher end, the device can also avoid the problem of slipping between the rubber lining and the top of the conveyor belt 103. Specifically, the secondary driven sprocket 403 rotates counterclockwise through the positioning shaft 201 to drive the positioning synchronous wheel 202 to rotate together, further making the front and rear two positioning synchronous belts 203 rotate around the left and right directions. The positioning synchronous wheel 202 rotates, and the positioning synchronous belt 203 rotates through the positioning seat 204 to drive the positioning rod 206, the positioning pressure plate 207, etc. to move together. When the positioning pressure plate 207 moves to the bottom of the center of a positioning synchronous wheel 202 located at the left end along with the positioning synchronous belt 203, the ball 209 corresponding to the positioning pressure plate 207 is just located at the left end curved surface position of the guide rail 2011. After that, the positioning synchronous belt 203 drives the positioning pressure plate 207 to move rightward, causing the ball 209 to move downward along the left end curved surface of the guide rail 2011 during the rightward movement until the ball 209 moves to the bottom horizontal section of the guide rail 2011. During this period, the ball 209 moves downward and presses the positioning rod 206 downward through the ball cage seat 208, so that the positioning rod 206 moves downward along the inner wall of the telescopic hole 205 and pushes the positioning pressure plate 207 to move downward together. At the same time, the return spring 2010 pulls up and accumulates force, thereby providing elastic potential energy for the positioning rod 206, the positioning pressure plate 207, the ball cage seat 208 and the ball 209 to return upward. As the positioning pressure plate 207 moves downward, it will contact the upper surface of the rubber lining at the top of the conveyor belt 103 and move to the right with the rubber lining. Due to the contact friction between the bottom of the positioning pressure plate 207 and the upper surface of the rubber lining The rubber lining can be prevented from slipping against the top of the conveyor belt 103 during feeding. When a positioning plate 207 that contacts the upper surface of the rubber lining moves to the right end of the device, the ball 209 corresponding to the positioning plate 207 just rolls along the bottom of the horizontal plane of the guide rail 2011 to the curved surface position at the rightmost end of the guide rail 2011. At this time, the rebound force of the reset spring 2010 is released, pushing the positioning rod 206, the positioning plate 207, the ball cage seat 208 and the ball 209 upward to reset, so that the bottom of the positioning plate 207 is separated from the upper surface of the rubber lining, so that the rubber lining can complete feeding from the rightmost end of the device.

[0051] The downward pressing distance of the positioning pressure plate 207 in the present device can be adjusted according to the thickness of the rubber lining to be fed. Specifically, the screw rod 303 is driven to rotate by manually rotating the hand wheel 302, and the inner thread tube 304 is further moved upward or downward along the axial direction of the screw rod 303 under the cooperation of the threads of the screw rod 303 and the inner thread tube 304. The movement of the inner thread tube 304 further drives the adjustment platform 305 to move up or down, and the upward or downward movement of the adjustment platform 305 further drives the front and rear guide rails 2011 to move together, so that the height of the front and rear guide rails 2011 is adjusted, thereby controlling the downward pressing distance of the ball 209, that is, adjusting the downward moving distance of the positioning pressure plate 207, so as to be suitable for the feeding service of rubber linings of different thicknesses, thereby improving the universality and flexibility of the present device.

[0052] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
