Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber drying equipment, specifically to a drying and conveying line for rubber production. Background Technology
[0002] The rubber production process requires a complete production line, including rubber collection, cleaning, creping, sun-drying, and drying. During the drying process, the creped rubber sheets are placed in sheet shape by a robotic arm on a suspended chain and then conveyed to the drying room for drying.
[0003] Chinese invention patent application number 2023110315079 discloses an automated system for loading, unloading, and drying film, including a film hanging system, a drying conveyor line, a drying chamber, a drying conveyor line, and a film picking system. The film hanging system is connected to the drying conveyor line, which is located inside the drying chamber. Both ends of the drying conveyor line are connected to the drying conveyor line and the film picking system, respectively. A pressing device is installed to ensure that the rubber does not fall out while keeping the film on the parallel rods, suspension chain, and material frame aligned at the same point, thus lifting the material in the center. This improves both the loading rate and the accuracy of the loading. Hanging fixtures are also included to allow for the reversal of the transport chain while reducing the failure rate, thereby increasing the system's versatility in the production process.
[0004] The above solution uses a robotic arm to press rubber sheets and then places the sheets on a suspended chain to be transported to the drying room for drying. However, it only utilizes part of the space in the drying room during the drying process, resulting in reduced efficiency. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a drying and transport line for rubber production, aiming to solve the problem of low space utilization in drying rooms.
[0006] This utility model provides a drying and conveying line for rubber production, including a drying chamber, rubber sheets, and an operating table. The drying chamber is characterized by an upper track and a lower track, which are parallel to each other outside the drying chamber. The upper track forms a ramp towards the entrance of the drying chamber. The upper and lower tracks are slidably connected at equal intervals by a hooking mechanism for hooking rubber sheets. The operating table is located near the lower track, and a pushing mechanism is fixedly connected to the operating table to push the rubber sheets from the lower track to the upper track at intervals, so that both the upper and lower tracks dry the rubber sheets.
[0007] The layered tracks allow for the use of spare space in the drying room for film drying, improving the space utilization of the drying room, thereby increasing film drying efficiency, shortening the time required for a single batch of rubber, and reducing production costs.
[0008] Furthermore, the upper and lower tracks are parallel and identical within the drying chamber. Both enter the drying chamber at the entrance and extend in a serpentine trajectory. After reaching the drying chamber's exit, the lower track exits in a straight line, while the upper track is equipped with a lifting ramp that extends downwards, parallel to the lower track, and then exits in a straight line. Both the upper and lower tracks include a sliding track and a lifting track. The lifting track is parallel to the sliding track and is located above the sliding track.
[0009] Furthermore, the hanging mechanism includes a hanging frame, a clamping plate, a connecting plate, and a slider. The clamping plate holds one side of the film, the clamping plate fits the shape of the hanging frame and slides within the hanging frame, the slider slides on the sliding track, one end of the connecting plate is hinged to the slider, and the other end of the connecting plate is hinged to the hanging frame. The hanging mechanism also includes a locking plate and a locking groove. The locking groove is opened along the length direction of the hanging track, one end of the locking plate is slidably connected to the locking groove, and the other end of the locking plate is fixedly connected to the slider.
[0010] Furthermore, the spacing between the hanging frames on the upper track is wider than that on the lower track; the distance between two hanging frames on the upper track is twice the distance between two hanging frames on the lower track. By using hanging frames with different spacing, a pushing mechanism can push the film from the lower track to the hanging frames on the upper track for separate conveying and drying. This increases the spacing between films in the same layer, improving the drying effect and resulting in more uniform film drying.
[0011] Furthermore, the pushing mechanism includes a rotating shaft, a first folding rod, a second folding rod, a push rod, a support frame, and a reciprocating motor. One end of the first folding rod is fixedly connected to the rotating shaft, and the other end of the first folding rod is hinged to one end of the second folding rod. The other end of the second folding rod is hinged to a push rod. The output end of the reciprocating motor is fixedly connected to the center of the rotating shaft. The reciprocating motor is fixedly connected to the operating table. The operating table has through slots for the first and second folding rods to move. The lower end of the support frame is fixedly connected to the operating table, and the middle part of the second folding rod overlaps with the upper end of the support frame. A locking groove is provided on the clamping plate, and the push rod moves and abuts against the locking groove when pushed. The pushing mechanism intermittently pushes the film from the lower track to the upper track into the drying chamber.
[0012] Compared with existing technologies, it has the following beneficial effects:
[0013] This invention provides a drying and conveying line for rubber production. By setting up layered tracks, the spare space in the drying room can be utilized for drying rubber sheets, which improves the space utilization rate of the drying room, thereby making the drying efficiency of rubber sheets higher, shortening the time required for a single batch of rubber sheets, and reducing production costs.
[0014] By using hanging frames with different spacing, a pushing mechanism can push the film on the lower track to the hanging frames on the upper track for separate conveying and drying. This increases the spacing between films in the same layer, improving the drying effect and making the film drying more uniform. Attached Figure Description

Detailed Implementation
[0025] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings:
[0026] like Figures 1 to 8 As shown, this utility model provides a drying and conveying line for rubber production, including a drying chamber 1, rubber sheets 2, and an operating table 3. The drying chamber 1 is characterized by having an upper track 4 and a lower track 5 arranged parallel to each other outside the drying chamber 1. The upper track 4 forms a ramp at the entrance of the drying chamber 1. The upper track 4 and lower track 5 are slidably connected at equal intervals by a hanging mechanism 6 for hanging the rubber sheets 2. The operating table 3 is located near the lower track 5, and a pushing mechanism 7 is fixedly connected to the operating table 3 to push the rubber sheets 2 from the lower track 5 to the upper track at intervals, so that both the upper track 4 and the lower track 5 dry the rubber sheets 2.
[0027] As another embodiment, such as Figures 2 to 5 As shown, the upper track 4 and the lower track 5 have parallel and identical trajectories within the drying chamber 1. Both enter at the entrance of the drying chamber 1 and extend in a serpentine trajectory, extending to the exit of the drying chamber 1. The lower track 5 then exits in a straight line, while the upper track 4 is equipped with a ramp that extends downwards, parallel to the lower track 5, and then exits in a straight line. The upper track 4 and the lower track 5 employ a suspended chain drive structure, where the hanging mechanism 6 clamps the film 2 and moves it along the track, thereby conveying the film 2 into the drying chamber 1. After the drying process is completed, it is conveyed to the next process step for further processing.
[0028] See Figure 4 Both the upper track 4 and the lower track 5 include a sliding track 41 and a lifting track 42. The lifting track 42 is parallel to the sliding track 41 and is located above the sliding track 41. The suspension chain structure is set inside the sliding track 41.
[0029] See Figure 4 and Figure 5 The hanging mechanism 6 includes a hanging frame 61, a clamping plate 62, a connecting plate 63, and a slider 64. The clamping plate 62 clamps one side of the film 2. The clamping plate 62 fits the shape of the hanging frame 61 and slides within the hanging frame 61. The slider 64 slides on the sliding track 41. One end of the connecting plate 63 is hinged to the slider 64, and the other end of the connecting plate 63 is hinged to the hanging frame 61. The hanging frame 61 connected to the upper track 4 does not have a clamping plate 62 inside, allowing the pushing mechanism 7 to periodically push the clamping plate 62 in the lower track 5 into the hanging frame 61 of the upper track 4, achieving simultaneous drying of the upper and lower tracks.
[0030] See Figure 5The mounting mechanism 6 also includes a clamping plate 65 and a clamping slot 66. The clamping slot 66 is opened along the length direction of the hanging track 42. One end of the clamping plate 65 is slidably connected to the clamping slot 66, and the other end of the clamping plate 65 is fixedly connected to the slider 64. The clamping slot 66 has two symmetrically opened sets. The two sets of clamping plates 65 extend into the two side clamping slots 66 respectively and are slidably connected to limit the swing of the slider 64 to a certain extent, so that the shape of the film 2 is more stable when the pushing mechanism 7 pushes the clamping plate 62 and the film 2.
[0031] See Figure 3 The spacing between the hanging frames 61 on the upper track 4 is wider than that on the lower track 5, and the distance between the two hanging frames 61 on the upper track 4 is twice the distance between the two hanging frames 61 on the lower track 5. This ensures that after the pushing mechanism 7 periodically pushes the film 2 on the lower track 5 to the upper track 4, the distance between the film 2 on the upper track 4 and the lower track 5 is the same.
[0032] As another embodiment, such as Figure 1 , Figure 7 as well as Figure 8 As shown, the pushing mechanism 7 includes a rotating shaft 71, a first folding rod 72, a second folding rod 73, a push rod 74, a support frame 75, and a reciprocating motor 76. One end of the first folding rod 72 is fixedly connected to the rotating shaft 71, and the other end of the first folding rod 72 is hinged to one end of the second folding rod 73. The other end of the second folding rod 73 is hinged to the push rod 74. The output end of the reciprocating motor 76 is fixedly connected to the center of the rotating shaft 71. The reciprocating motor 76 is fixedly connected to the operating table 3. The operating table 3 has a through slot for the first folding rod 72 and the second folding rod 73 to move. The lower end of the support frame 75 is fixedly connected to the operating table 3, and the middle part of the second folding rod 73 overlaps with the upper end of the support frame 75. The reciprocating motor 76 rotates reciprocally, driving the first folding rod 72 to perform circumferential reciprocating motion. This, in turn, drives the second folding rod 73 to reciprocate towards the lower track 5 via a hinge. Consequently, the push rod 74 reciprocates to push the clamping plate 62 of the lower track 5, pushing the clamping plate 62 into the hanging frame 61 under the upper track 4. The support frame 75 provides support for the second folding rod 73, preventing it from falling.
[0033] See Figure 8 The clamping plate 62 has a locking groove, and the push rod 74 moves and abuts against the locking groove when pushed. When the push rod 74 contacts the clamping plate 62, it first contacts the locking groove, which limits the push rod 74 to a certain extent, making the pushing process more stable.
[0034] The working principle of a rubber drying and conveying line disclosed in this application is as follows: During operation, after the sheet-hanging device transfers the cut rubber sheets 2 one by one to the lower track 5, the clamping plates 62 hold the rubber sheets 2 and move them along the lower track 5 towards the drying chamber 1. During this process, the upper track 4 and the hanging frame 61 on the lower track 5 move synchronously. A reciprocating motor 76 drives the first folding rod 72, which in turn drives the second folding rod 73, causing the push rod 74 to reciprocate and push the clamping plates 62 under the lower track 5 at intervals. When the clamp 62 is driven, it slides within the hanging frame 61, moving from the hanging frame 61 under the lower track 5 to the hanging frame 61 under the upper track 4. The upper track 4 is at a different vertical position from the lower track 5 via a set lifting ramp. The upper track 4 and the lower track 5 carry the film 2 into the drying chamber 1 and arrange it in a serpentine pattern. After the film 2 is dried in the drying chamber 1, the film 2 on the upper track 4 and the lower track 5 is simultaneously conveyed out of the drying chamber 1 and, after passing through the lifting ramp again to the same horizontal position, proceeds to the next process.
[0035] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
