Description

Technical Field

[0001] The invention relates to the technical field of feeding machines, in particular to a feeding machine which can be lifted and retracted forward and backward. Background Art

[0002] A feeder is an automated device used to deliver raw materials to a production line at a preset rate or rhythm. Its core function is to ensure accurate, continuous, and efficient material feeding, reducing manual intervention and improving production efficiency and safety. It is primarily used in industrial production, environmental protection, construction, and other fields.

[0003] Among them, in industrial production, a feeder is usually used to transport materials such as rubber, and the rubber is fed into equipment such as an internal mixer for crushing and mixing. In the existing technology, a conveyor belt is usually used to transport the rubber, and an inclined inclined plate is set at the end of the conveyor belt. One end of the inclined plate is located below the conveyor belt, and the other end is aligned with the feeding port of other equipment. The rubber coming down from the conveyor belt can better enter the subsequent processing equipment through the diversion of the inclined plate; however, in the process of the inclined plate transporting the rubber, the rubber itself has a certain viscosity (especially hot melt adhesive, rubber, etc.), and the dust or sticky substances on the surface of the rubber (such as incompletely solidified colloids, impurities, etc.) will gradually adhere to the inclined plate. The sticky substances accumulate on the surface of the inclined plate. If they are not cleaned in time, they will cause pollution to the subsequent rubber and affect the accuracy of the inclined plate in transporting the rubber, because the accumulation of sticky substances will cause the rubber to encounter a certain resistance when it leaves the inclined plate, and there is a problem of rubber accumulation on the inclined plate.

The term "and / or" as used in this description includes any and all combinations of one or more of the associated listed items.

[0024] The following combination Figures 1-11 The invention describes a feeding machine which can be raised and lowered and can be telescopically extended forward and backward.

[0025] like Figures 1-10 As shown, in one embodiment, a feeder that can be raised and lowered and telescopically extended forward and backward includes a support frame 1, a lifting platform 2, a conveying frame 3, a positioning frame 4, a sliding plate 5, a fixed frame 6, a movable rod 7, a partition 9, a horizontal plate 10, a fixed cylinder 11, a fixed plate 12, a scraper 13 and a shaking component 8.

[0026] Among them, the lifting platform 2 can slide up and down relative to the supporting frame 1 to adjust the height, the conveying frame 3 can slide left and right relative to the lifting platform 2, the positioning frame 4 is fixedly installed at the bottom of the conveying frame 3, the sliding plate 5 is movably installed on the positioning frame 4, and the number of fixed frames 6 is set to two, one on the left and one on the right, and a movable rod 7 is rotatably installed between the two fixed frames 6. The partition 9 is fixedly sleeved on the outside of the movable rod 7. The cross plate 10 is fixedly installed on the positioning frame 4, and its height is higher than the partition 9. The fixing cylinder 11 is fixedly installed at the bottom of the cross plate 10 and a slot 121 is opened at the bottom. Scrapers 13 are movably provided on both sides of the slot 121. The scraper 13 is movably abutted against the surface of the partition 9, and the shaking component 8 can drive the fixed plate 12 and the partition 9 to shake.

[0027] After the rubber material is placed on the conveying rack 3, the lifting platform 2 is started, and the lifting platform 2 drives the conveying rack 3 and the positioning rack 4 to move upward relative to the support frame 1. The rubber material will eventually be put into the internal mixer. The feeding port of the internal mixer is at a certain height from the ground. The upward movement of the lifting platform 2 can increase the height of the conveying rack 3, which is convenient for putting the accumulated rubber material into the internal mixer. After the lifting platform 2 is raised to the specified height, the conveying rack 3 and the positioning rack 4 can move horizontally relative to the lifting platform 2, and the conveying rack 3 moves with the rubber material accumulated on the surface toward the feeding port of the internal mixer until it reaches above the feeding port. At this time, the sliding plate 5 is moved horizontally, and the sliding plate 5 drives the fixed frame 6, the movable rod 7 and the partition 9 to move together. After the rubber material has been fed to the mixing machine, the partition 9 will be restored to a horizontal state and then moved to the initial position in the opposite direction. During the movement, the surface of the partition 9 will abut against the scraper 13, and the scraper 13 will scrape off the dust and sticky substances attached to the surface of the partition 9 to ensure the cleanliness of the surface of the partition 9. Subsequently, the shaking component 8 provided in the fixed cylinder 11 will drive the fixed plate 12 and the scraper 13 to shake, so as to shake off the foreign matter on the scraper 13 and ensure the cleanliness of the scraper 13.

[0028] See Figure 6-Figure 7 and Figures 9-11 As shown, in this embodiment, the shaking component 8 includes a cylinder 81, which is movably arranged in the fixed cylinder 11, and a cylinder 82 is movably embedded in the cylinder 81. A plurality of steel balls 83 are arranged in a circular array at the bottom of the cylinder 82, and a disc 84 is movably arranged at the bottom of the cylinder 81. A plurality of circular holes 85 are opened in a circular array on the surface of the disc 84, and the steel balls 83 are movably abutted against the circular holes 85. A vertical rod 86 is fixedly arranged at the bottom of the disc 84, and the vertical rod 86 movably passes through the cylinder 81 and the end is fixedly connected to the fixed plate 12. The disc 84 and the inner wall of the cylinder 81 are connected by a shaking spring 87.

[0029] Specifically, when it is necessary to clean the surface of the partition 9, the bottom of the scraper 13 is in contact with the partition 9, and a part of the scrapers 13 on both sides of the notch 121 extends to the outside of the fixed plate 12. During the movement of the partition 9 relative to the scraper 13, the scraper 13 can scrape off the sticky material attached to the surface of the partition 9. A cooling component can be set in the scraper 13 to cool the scraper 13. The cooled scraper 13 can make the sticky material solidify quickly, which is convenient for removing it. After the partition 9 moves past the bottom of the scraper 13, the cylinder 81 moves upward along the fixed cylinder 11. The upward movement of the cylinder 81 will drive the cylinder 82, the disc 84, the vertical rod 86, the fixed plate 12, the scraper 13 and other components to move upward together, and the upward movement of the cylinder 82 At the same time, it will rotate relative to the cylinder 81. The rotation of the cylinder 82 will drive multiple steel balls 83 to rotate together. During the rotation of the steel balls 83, they will alternately abut against the circular holes 85. When the steel balls 83 move out of the circular holes 85, they will push the disc 84, the vertical rod 86, the fixed plate 12 and the scraper 13 to move downward, compressing the shake spring 87. When the steel balls 83 move into the circular hole 85, the shake spring 87 will restore the state and pull the disc 84, the vertical rod 86, the fixed plate 12 and the scraper 13 upward to their initial positions. The rotation of the steel balls 83 will realize the up and down reciprocating movement of the vertical rod 86. Due to the characteristics of the spring, a shaking feeling will be generated during the up and down reciprocating movement, which can accelerate the shedding of the sticky material on the scraper 13.

[0030] See Figure 6-Figure 7 and Figure 9-10 As shown, in this embodiment, a vertical groove 811 is opened on the outside of the cylinder 81, a curved groove 821 is opened on the outside of the cylinder 82, and a limiting rod 14 is fixedly provided on the inner wall of the fixed cylinder 11. One end of the limiting rod 14 slides in contact with the curved groove 821, and the limiting rod 14 is slidably connected to the vertical groove 811.

[0031] Specifically, when the cylinder 81 moves upward along the fixed cylinder 11, the limiting rod 14 slides relative to the vertical groove 811, and the cylinder 82 moves upward together with the cylinder 81. During the movement, the cylinder 82 rotates through the cooperation of the limiting rod 14 and the curved groove 821. The rotation of the cylinder 82 drives the steel ball 83 to rotate, and finally the fixed plate 12 and the scraper 13 can be shaken, thereby accelerating the falling of the viscous material.

[0032] See Figure 6 and Figure 8 As shown, in this embodiment, a round rod 15 is movably provided on one side of the fixed plate 12, the end of the round rod 15 is located in the groove 121 and a rotating plate 16 is fixedly sleeved on the outside, and both ends of the rotating plate 16 are movably connected to a swinging plate 17, and the swinging plate 17 is movably connected to one side of the scraper 13 at one end away from the rotating plate 16.

[0033] Specifically, when it is necessary to clean the surface of the partition 9, a part of the scrapers 13 on both sides of the bottom of the fixed plate 12 is located outside the slot 121, so that the scrapers 13 can scrape off the sticky material on the partition 9. After the partition 9 moves over the bottom of the scraper 13, it is necessary to clean the sticky material attached to the scraper 13. Although the cooling component provided in the scraper 13 can solidify the sticky material to facilitate removal, the solidified sticky material may still adhere to the surface of the scraper 13. At this time, the round rod 15 can be rotated. The rotation of the round rod 15 drives the rotating plate 16 to rotate, thereby rotating the swing plate 17. The rotation of the swing plate 17 can realize the centering movement of the scrapers 13 on both sides, and the scraper 13 moves toward the inside of the slot 121. The side of the scraper 13 with the sticky material will also enter the inside of the slot 121. During the entry process, the sticky material will abut against the outer wall of the slot 121, and the sticky material will fall off from the surface of the scraper 13.

[0034] See Figure 6 As shown, in this embodiment, an arcuate groove 151 is formed on the outer side of the round rod 15 away from the rotating plate 16 , and a cross bar 18 is fixedly provided on one side of the fixed cylinder 11 , and the end of the cross bar 18 away from the fixed cylinder 11 is slidably fitted in the arcuate groove 151 .

[0035] Specifically, when the cylinder 81 moves upward along the fixed cylinder 11, it will drive the vertical rod 86, the fixed plate 12 and the scraper 13 to move upward together, and the round rod 15 will also move upward. The cross bar 18 will move downward relative to the arc groove 151, which will drive the round rod 15 to rotate. The rotation of the round rod 15 can realize the movement of the scrapers 13 on both sides into the groove 121, and the sticky material attached to the surface of the scraper 13 is scraped off through the action of the outer wall of the groove 121. In addition, during the upward process of the cylinder 81, the steel ball 83 is driven to rotate by the cooperation of the limit rod 14 and the curved groove 821. The rotation of the steel ball 83 can eventually realize the shaking of the scraper 13. Therefore, when the cylinder 81 moves upward relative to the fixed cylinder 11, the scraper 13 will also shake during the movement towards the center, which can further improve the efficiency of removing the sticky material attached to the scraper 13.

[0036] See Figure 6-Figure 7 As shown, in this embodiment, a lifting rack 19 is fixedly provided on the top of the cylinder 81, and a rotating rod 20 is movably provided on one side of the fixed cylinder 11. One end of the rotating rod 20 is located in the fixed cylinder 11 and an incomplete gear 21 is fixedly sleeved at the end. The incomplete gear 21 is engaged with the lifting rack 19 for transmission.

[0037] Specifically, when the cylinder 81 needs to be moved upward, the rotating rod 20 is rotated. The rotation of the rotating rod 20 will drive the incomplete gear 21 to rotate. The rotation of the incomplete gear 21 will drive the lifting rack 19 to move upward. The upward movement of the lifting rack 19 will drive the cylinder 81 to move upward relative to the fixed cylinder 11.

[0038] See Figure 4-Figure 6 As shown, in this embodiment, a connecting plate 22 is fixedly provided on the top of one of the fixing frames 6, and two movable racks 23 are fixedly provided on one side of the connecting plate 22, one up and one down, one in front and one behind. A positioning gear 24 is fixedly provided on the end of the rotating rod 20 away from the incomplete gear 21, and the movable rack 23 is alternately engaged with the positioning gear 24 for transmission.

[0039] Specifically, in the initial state, the partition 9 is still at the bottom of the conveying frame 3. At this time, the bottom of the scraper 13 is flush with the surface of the partition 9. At this time, the motor of the sliding plate 5 is started, and the sliding plate 5 moves along the positioning frame 4 to the outside of the conveying frame 3. The movement of the sliding plate 5 will drive the fixed frame 6, the movable rod 7 and the partition 9 to move outward together. During the movement of the partition 9, it will abut against the scraper 13, which can remove some foreign matter. When the partition 9 passes through the bottom of the scraper 13, the fixed frame 6 will drive the connecting plate 22 and the two moving racks 23 to move toward the side of the positioning gear 24. The upper moving rack 23 will first engage with the positioning gear 24, thereby driving the positioning gear 24 and the rotating rod 20 to rotate clockwise, and the lifting rack 19 and the cylinder 81 are driven to move upward through the incomplete gear 21. The upward movement of the cylinder 81 will realize the scraper 13 moving in the middle. It will also shake, accelerating the separation of the sticky material, and then the moving rack 23 at the bottom will mesh with the positioning gear 24, thereby driving the positioning gear 24 and the rotating rod 20 to rotate in the opposite direction, so that a part of the scraper 13 can be moved back to the outside of the slot 121; similarly, when the partition 9 is used up, the sliding plate 5 moves back to the initial position, which will drive the fixed frame 6, the connecting plate 22 and the two moving racks 23 to move. When moving in this direction, the moving rack 23 at the bottom will first mesh with the positioning gear 24 to realize the positioning gear 24 to rotate clockwise, which can drive the cylinder 81 to move upward, and then the moving rack 23 at the top will mesh with the positioning gear 24 to realize the positioning gear 24 and the rotating rod 20 to rotate counterclockwise to the initial state. The bottom of the scraper 13 will be flush with the surface of the partition 9 in the parallel moving state, which can scrape off the sticky material on the surface of the partition 9.

[0040] See Figure 5 As shown, in this embodiment, a positioning plate 25 is fixedly provided on one side of the fixing frame 6, a driving rack 26 is slidably provided in the middle of the positioning plate 25, and a driving gear 27 is fixedly provided at the end of one side of the movable rod 7, and the driving gear 27 is engaged with the driving rack 26 for transmission.

[0041] Specifically, when it is necessary to use the partition 9 to unload materials, the sliding plate 5 is moved toward the outside of the conveying frame 3, and the sliding plate 5 drives the fixed frame 6, the movable rod 7, the partition 9, and the positioning plate 25 to move outward together. When the partition 9 is almost completely moved to the outside of the conveying frame 3, the driving rack 26 is moved horizontally along the positioning plate 25. The driving rack 26 moves in the direction away from the partition 9, which will drive the driving gear 27 to rotate clockwise, and the movable rod 7 also rotates clockwise, which will drive the partition 9 to rotate clockwise, and the partition 9 becomes inclined, so that the rubber material falling from the conveying frame 3 can fall onto the partition 9 and slide into the opening of the internal mixer.

[0042] See Figure 5 As shown, in this embodiment, the positioning plate 25 is rotatably provided with a connecting rod 28 on one side of the driving rack 26 , and a limiting gear 29 is fixedly sleeved on the outside of the connecting rod 28 , which meshes with the driving rack 26 for transmission.

[0043] Specifically, when it is necessary to use the partition 9 to unload materials, the sliding plate 5 is moved toward the outside of the conveying frame 3, and the sliding plate 5 drives the fixed frame 6, the movable rod 7, the partition 9, and the positioning plate 25 to move outward together. When the partition 9 is almost completely moved to the outside of the conveying frame 3, the connecting rod 28 is rotated clockwise, and the connecting rod 28 drives the limit gear 29 to rotate clockwise, thereby driving the drive rack 26 to move in the direction away from the partition 9, and the drive gear 27 will rotate clockwise to drive the partition 9 to tilt.

[0044] See Figure 3-Figure 5 As shown, in this embodiment, an L-shaped plate 30 is fixedly provided on one side of the positioning frame 4, and a horizontal groove 301 and an oblique groove 302 are provided on the L-shaped plate 30, which are connected to each other. A swing frame 31 is fixedly provided on the end of the connecting rod 28 away from the positioning plate 25, and the swing frame 31 is slidably connected to the horizontal groove 301 and the oblique groove 302 on the end away from the connecting rod 28.

[0045] Specifically, the sliding plate 5 is moved toward the outside of the conveying frame 3, and the sliding plate 5 will drive the fixed frame 6 to move together. The end of the swing frame 31 away from the connecting rod 28 will first slide along the horizontal groove 301 opened in the L-shaped plate 30. At this time, the partition 9 moves horizontally. When one end of the swing frame 31 moves into the inclined groove 302, it will drive the swing frame 31 to rotate. The rotation of the swing frame 31 drives the connecting rod 28 and the positioning gear 24 to rotate clockwise, so that the driving rack 26 moves, and finally the partition 9 can be tilted to facilitate unloading.
