Description

Technical Field

[0001] The invention relates to the technical field of insulating paper production and feeding, in particular to an insulating paper production and feeding device capable of quantitative feeding. Background Art

[0002] Insulation paper is widely used in electrical insulation due to its advantages such as electrical properties and heat resistance. During the production of insulation paper, raw materials (such as pulp, fiber, additives, etc.) need to be processed. During this process, a feeding device is needed to transport the raw materials to various processing links, such as feeding granular solid additives;

[0003] For example, the patent disclosed in the prior art with the publication number "CN117533729A" is named "Hydraulic Conveyor", which discloses that a conveyor belt is provided on the outside of the support assembly, and the conveyor belt can realize material transportation. By arranging an interference unloading assembly inside the support assembly, the interference unloading assembly can guide the material on the conveyor belt to the side to realize unloading, thereby achieving the effect of changing the unloading position of the conveyor belt. At the same time, the interference unloading assembly can slide inside the support assembly so that the device can realize decentralized unloading of the material. A hydraulic adjustment assembly is provided at one end of the support assembly. The hydraulic adjustment assembly includes a support arm and a movable arm. The support arm, the movable arm and the support assembly form a triangular structure. The triangular structure can be adjusted by adjusting the hydraulic rod inside the hydraulic adjustment assembly, so that the inclination angle of the device can be adjusted. During the adjustment process, the fulcrum of the device can be adjusted accordingly, thereby ensuring the stable operation of the device after adjustment. The bottom end of the support arm is provided with a movable arm through a pin shaft, and a walking wheel is provided at the end where the support arm and the movable arm are close to each other. The walking wheel can act as a fulcrum and can rotate so that the fulcrum can be adaptively adjusted. The patent name disclosed in "CN118358959B" is "A quantitative feeding device for titanium dioxide production". It discloses that the angle and position of the conveyor can be adjusted according to different production environments. Hold the handle and push the connecting frame backward. The connecting frame drives the sliding frame, the card block, the wedge block and the semicircular block to move backward, so that the card block on the rear side is moved out of the bayonet, the rotating ring is loosened, and the semicircular block is moved out of the semicircular groove on the rear side. The spring 2 is compressed, and then the semicircular block corresponds to the semicircular groove on the front side. Under the action of the spring 2, the semicircular block enters the semicircular groove on the front side. At this time, the staff pushes the connecting frame backward. The connecting frame will have a certain resistance, which can play a positioning role, indicating that the card block on the rear side has been moved out of the card slot, and can prevent the connecting frame, sliding frame and card block from moving at will. Then the staff turns the casing and adjusts the angle of the conveyor to align the discharge end of the conveyor with the production equipment. After adjusting the angle of the conveyor, continue to push the connecting frame backward, driving the sliding frame, card block, wedge block and semicircular block to continue to move backward, so that the semicircular block is moved out of the semicircular groove on the front side, and the card block on the front side is inserted into the card slot to clamp the rotating ring, thereby fixing the angle of the conveyor and preventing the conveyor angle from shifting.

[0004] The supporting frames in the feeding devices in the above-mentioned prior art are mostly assembled and installed by welding or screws. In this way, when the feeding device is used for a long time, the conveyor belt inside it is damaged due to long-term wear and tear, and the conveyor belt needs to be replaced. It takes a long time to disassemble one side of the supporting frame and subsequently assemble it, which makes it inconvenient to replace the conveyor belt with the supporting frame in the feeding device. At the same time, although the above-mentioned feeding device can achieve quantitative feeding, its structure is relatively complex and it is not convenient to carry out quantitative feeding well. Therefore, we propose a feeding device for insulating paper production that can feed quantitatively in order to solve the above-mentioned problems. Summary of the Invention

[0010] Preferably, the disassembly and regulation mechanism includes a sliding seat that is engaged and slidably connected to the upper surface of the front end of the supporting frame. The two sliding seats are connected by a synchronization rod in an inverted "U" shape. A rotating rod is installed through the internal groove in the front of the sliding seat. The rotating rod is fixedly connected to the lower internal part of the front connecting seat. A first vortex spring is nested and connected to the outer side of one end of the rotating rod, and a first control rope is wrapped around the outer side of the other end of the rotating rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the feeding device for producing insulating paper capable of quantitative feeding, the front connecting seat drives the front supporting frame to rotate from a vertical shape to a horizontal shape, and then facilitates the pulling of the conveyor belt forward for replacement, which is convenient to operate, saves time and effort, and in the later stage, only the second electric push rod needs to drive the sliding seat to move backward and reset, so that the front supporting frame can be reversely rotated and reset, and only the conveyor belt needs to be controlled to rotate intermittently for a fixed time, so that the conveyor belt can be intermittently fed quantitatively, thereby meeting the later processing requirements.

When the front connecting seat continues to move forward, the rotating rod and the front connecting seat can be driven to rotate through the first control rope, so that the front connecting seat drives the front supporting frame to rotate from a vertical state to a horizontal state, thereby facilitating the conveyor belt to be pulled forward for replacement, which is convenient to operate, saves time and effort, and later on, only needs to drive the sliding seat to move backward and reset by the second electric push rod, so that the front supporting frame can be reversely rotated and reset;

[0018] By using the upper limit plate and the side baffle in the quantitative control component, the granular solid additive on the conveyor belt on the right side of the upper limit plate can be kept at a fixed thickness. Therefore, the conveyor belt can be intermittently fed with quantitative feeding by simply controlling the intermittent rotation of the conveyor belt for a fixed time, thus meeting the needs of later processing.

[0019] By sliding the second support column and the first support column, when the conveyor belt is conveying raw materials, the weight of the raw materials can drive the support frame and the first support column to move downward, thereby making the rubber connection pad closely contact with the ground, without the need to lock multiple moving wheels one by one, thereby improving the stability of the entire feeding device during use;

[0020] During the process of the front support frame moving forward and rotating, the second control rope is pulled by the synchronization rod, so that the second control rope drives the threaded rod to rotate, and the threaded rod drives the tensioning roller connected to the outer thread to move upward, thereby making the conveyor belt in a relaxed state, which can further facilitate the separation of the conveyor belt from the roller and facilitate the replacement of the conveyor belt at a later time.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-13 , the present invention provides the following technical solutions:

[0037] Example 1: The feeding device for producing and feeding insulating paper with quantitative feeding in this embodiment can control the front support frame 2 to move forward and rotate by disassembling the regulating mechanism, so as to facilitate the conveyor belt 4 outside the roller 3 to be pulled forward for replacement in the later stage, which saves time and effort. For the specific structure, please refer to the attached Figures 1-8As shown, it includes a rear support frame 1, and a roller 3 installed on the front side of the rear support frame 1, the outer side of the roller 3 is connected to the conveyor belt 4, the rear side of the rear support frame 1 is connected to the quantitative control component on the conveyor belt 4 through a fixed frame, and the front end of the roller 3 is connected to the front support frame 2, and two groups of support frames 8 are provided below the conveyor belt 4. The front connecting seat 7 installed below the front support frame 2 is connected to the front end upper surface of the support frame 8 through a disassembly control mechanism, and the bottom of the rear support frame 1 is connected to the support frame through a rear connecting seat 13. 8 is connected to the upper surface of the rear end of the support frame 8, two groups of first support columns 9 are symmetrically installed below the support frame 8, and the second support column 10 is connected to the inside of the first support column 9. The quantitative control component includes an upper limit plate 5 arranged above the conveyor belt 4, and the front and rear sides of the upper limit plate 5 are installed with side baffles 51. The left part of the side baffle 51 and the left side of the upper limit plate 5 are both inclined. The distance between the bottom surface of the upper limit plate 5 and the upper surface of the conveyor belt 4 is greater than the distance between the bottom surface of the side baffle 51 and the upper surface of the conveyor belt 4.

[0038] A first electric push rod 6 is installed on the right side of the rear support frame 1. A blocking plate 61 is fixed to the output end of the first electric push rod 6. The left side of the blocking plate 61 is fitted with the right side of the conveyor belt 4. The support frame 8 is arranged in an inverted "U" shape. The disassembly and regulation mechanism includes a sliding seat 11 that is engaged and slidably connected to the upper surface of the front end of the support frame 8. The two sliding seats 11 are connected by a synchronization rod 12 in an inverted "U" shape. A rotating rod 111 is installed through the internal slot in front of the sliding seat 11. The rotating rod 111 is connected to the The lower interior of the front connecting seat 7 is fixedly connected, and a first vortex spring 112 is nested and connected to the outside of one end of the rotating rod 111, and a first control rope 113 is wrapped around the outside of the other end of the rotating rod 111. The rear end of the first control rope 113 is connected to the supporting frame 8 through a guide wheel, and a second electric push rod 114 is installed above the supporting frame 8 on the left. The front end of the second electric push rod 114 is connected to the sliding seat 11 on the left, and the front connecting seat 7 forms a rotating structure with the sliding seat 11 through the rotating rod 111.

[0039] First, the entire feeding device is moved into the working area through the moving wheel at the bottom of the second support column 10, and then the entire feeding device can be used. The granular solid additives needed for insulating paper production are poured into the upper left side of the conveyor belt 4. At this time, the motor at the rear right side of the rear support frame 1 is started, and the motor drives the roller 3 on the right side to rotate. At this time, the roller 3 drives the conveyor belt 4 to rotate to feed the additive. When the additive moves to the position below the upper limit plate 5, the thickness of the additive can be controlled by the upper limit plate 5, so that the additive on the conveyor belt 4 on the right side of the upper limit plate 5 is a fixed thickness. Then, after the conveyor belt 4 conveys the additive for a certain period of time, the rotation of the conveyor belt 4 is stopped. At this time, the first electric push rod 6 is started to drive the blocking plate 61 to move downward. At this time, the left side of the blocking plate 61 is in contact with the right side of the conveyor belt 4 to prevent the raw materials on the conveyor belt 4 from falling. Repeat this operation to control the conveyor belt 4 to rotate intermittently for a fixed time, so that the conveyor belt 4 can be intermittently fed quantitatively to meet the later processing requirements.

[0040] When the feeding device has been used for a long time and the conveyor belt 4 inside it is damaged and needs to be replaced, the second electric push rod 114 is started at this time, and the second electric push rod 114 drives the sliding seat 11 on the left to slide forward on the supporting frame 8. At this time, the sliding seat 11 on the left drives the sliding seat 11 on the right to slide forward together through the synchronization rod 12. At this time, the sliding seat 11 drives the front connecting seat 7 and the front supporting frame 2 to move forward together. At this time, the front end of the roller 3 is separated from the receiving hole inside the front supporting frame 2. At this time, the sliding seat 11 continues to move forward. At this time, the sliding seat 11 straightens the first control rope 113 with a certain length reserved, and continues to pull the first control rope 113. Then the first control rope 113 drives the rotating rod 111, the front connecting seat 7 and the front supporting frame 2 to rotate. The first vortex spring 112 accumulates force, causing the front connecting seat 7 and the front supporting frame 2 to rotate from a vertical state to a horizontal state. At this time, the front end of the roller 3 is exposed, and the conveyor belt 4 on the outside of the roller 3 is pulled forward, so that the roller 3 is separated from the conveyor belt 4, and then the new conveyor belt 4 is put on the outside of the roller 3, and then the second electric push rod 114 is started to drive the sliding seat 11 on the left to slide backward on the supporting frame 8. At this time, as shown above, the front connecting seat 7 and the front supporting frame 2 are automatically driven to rotate to a vertical state through the stored force of the first vortex spring 112, and then the front connecting seat 7 and the front supporting frame 2 are moved backward, so that the front end of the roller 3 is inserted into the receiving hole in the front supporting frame 2, so that it is convenient to disassemble and replace the conveyor belt 4, and the operation is convenient, saving time and effort.

[0041] Example 2: The feeding device for producing insulating paper with quantitative feeding in this embodiment can improve the stability of the feeding device when in use and avoid the movement of the feeding device. For the specific structure, refer to the attached Figure 9-10As shown, a connecting frame 91 is installed on the bottom surface of the first support column 9, and a connecting pad 92 made of rubber is fixed on the bottom surface of the connecting frame 91. The front and rear connecting frames 91 are connected by a connecting column 93. A load-bearing spring 94 is installed inside the upper part of the first support column 9. The second support column 10 is slidably connected to the lower part of the first support column 9. The upper part of the second support column 10 is connected to the lower end of the load-bearing spring 94, and the second support column 10 is arranged through the interior of the connecting frame 91.

[0042] When the conveyor belt 4 is transporting raw materials, the weight of the raw materials themselves will drive the rear support frame 1, the front support frame 2 and the support frame body 8 to move downward. At this time, the support frame body 8 drives the first support column 9, the connecting frame 91 and the connecting pad 92 to move downward. At this time, the second support column 10 squeezes the load-bearing spring 94, and the bottom surface of the rubber connecting pad 92 is in close contact with the ground, so there is no need to lock multiple moving wheels one by one, which can improve the stability of the entire feeding device during use. When there is no raw material on the conveyor belt 4, the stored force of the load-bearing spring 94 can automatically drive the first support column 9 and the support frame body 8 to rise and reset (the elastic force of the load-bearing spring 94 is greater than the sum of the gravity of all components above the load-bearing spring 94, so when there is no raw material on the conveyor belt 4, the first support column 9 will not fall).

[0043] Example 3: The feeding device for producing and feeding insulating paper with quantitative feeding in this embodiment can further facilitate the later pulling out of the conveyor belt 4 outside the roller 3 for replacement. For the specific structure, refer to the attached Figure 11-13 As shown, a threaded rod 15 is installed in a groove on the front side of the rear support frame 1. The outer side of the threaded rod 15 is threadedly connected to the rear end of the tensioning roller 14. The bottom of the tensioning roller 14 is in contact with the conveyor belt 4. The upper outer side of the threaded rod 15 is nested with a second vortex spring 152. The lower outer side of the threaded rod 15 is wrapped with a second control rope 151. The rear side of the synchronization rod 12 is connected to the front end of the second control rope 151.

[0044] When the synchronous rod 12 moves forward, the synchronous rod 12 will pull the second control rope 151 on the rear side, and the second control rope 151 will drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, it drives the tensioning roller 14 connected by the outer thread to rise. At this time, the second vortex spring 152 accumulates force, and the conveyor belt 4 is in a relaxed state. Therefore, it is convenient to pull the relaxed conveyor belt 4 out of the roller 3 and separate it later, so as to facilitate the replacement of the new conveyor belt 4 later. When the new conveyor belt 4 is replaced on the roller 3, as shown above, the synchronous rod 12 moves backward and resets, and the threaded rod 15 is driven to rotate in the opposite direction by the stored force of the second vortex spring 152. At this time, the tensioning roller 14 moves downward and resets to pull the conveyor belt 4, putting the conveyor belt 4 in a tensioned state, so that the conveyor belt 4 can perform feeding operations well in the later stage, thereby completing a series of tasks.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
