Description

Technical Field

[0001] The utility model relates to a plate blockage detection device for plate drying equipment, which is mainly used for detecting whether a material conveying roller group in the plate drying equipment has a plate blockage. Background Art

[0002] At present, the material transmission mechanism used in plate drying equipment is mainly a roller conveyor roller group. Due to certain differences in the specifications and shapes of the plates, the roller conveyor roller group may occasionally be blocked during the transmission of the plate materials, that is, the plate materials are blocked between the upper roller and the lower roller of the roller conveyor roller group.

[0003] Due to the extremely high internal ambient temperature of sheet drying equipment, it's impossible to use sensors or testing equipment to directly monitor the position changes of the conveyor rollers in real time, resulting in material blockages often going undetected. As the blockage intensifies, the subsequent incoming sheet material will likely increase in thickness. As the blockage increases, the distance between the sheet material and the heat source shortens, posing a serious risk of fire.

[0004] Therefore, the purpose of this utility model is to design a plate blockage detection device for plate drying equipment that can effectively detect the position of the roller conveyor roller group in real time in a high temperature environment, thereby providing real-time feedback on the operation status of the roller conveyor roller group to improve the operation safety of the equipment. Summary of the Invention

[0005] In response to the technical problems existing in the above-mentioned prior art, the present invention provides a plate blockage detection device for plate drying equipment, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A plate blockage detection device for plate drying equipment, comprising:

[0008] Several material conveying roller groups are arranged in a high and low distribution in the corresponding plate drying equipment for conveying the plates, and the material conveying roller groups respectively include an upper roller and a lower roller arranged above and below;

[0009] A plurality of driving members are respectively fixedly connected to the ends of the upper roller, and a follower is movably provided on the outside of the driving member. The follower is provided with a stroke limiting mechanism corresponding to the driving member. When the movement distance of any driving member exceeds a set value, the driving member contacts the stroke limiting mechanism and drives the follower to move through the stroke limiting mechanism;

[0010] The detection mechanism includes a plate blockage detection sensor arranged outside the plate drying equipment and a movable part movably arranged at the detection end of the plate blockage detection sensor. The movable part is connected to the driven part through a corresponding transmission mechanism.

[0011] The stroke limiting mechanism includes a plurality of long holes provided on the driven member, and the ends of the driving member not connected to the upper roller respectively penetrate into the corresponding long holes.

[0012] The stroke limiting mechanism includes a plurality of shift blocks fixedly connected to the driven member, the shift blocks face the driving member and are respectively located on the upper side of the corresponding driving member.

[0013] The driving member is a shaft member, and the driven member is a long rod member.

[0014] The transmission mechanism includes a driving shaft rotatably mounted on the plate drying equipment, the inner end of the driving shaft is fixedly connected to a corresponding connecting plate, the end of the connecting plate not connected to the driving shaft is provided with a corresponding long guide hole, and the driven member is fixedly connected to a limiting shaft located in the long guide hole.

[0015] The movable member is arranged in a plate shape and is fixedly connected to the outer end portion of the driving shaft member.

[0016] There are two plate blocking detection sensors, and the movable member is provided with two detection parts corresponding to the plate blocking detection sensors.

[0017] The two blocking plate detection sensors are arranged one above the other. During the rotation of the movable member, the detection portion sequentially leaves the detection sensor located on the upper side and the detection sensor located on the lower side.

[0018] Advantages of this utility model:

[0019] 1) This utility model is equipped with a driving member, a driven member, and a stroke limiting mechanism, enabling it to be used in high-temperature environments. When the travel distance of any driving member exceeds a set value, the driving member contacts the stroke limiting mechanism and drives the driven member to move. As the driven member moves, the transmission mechanism drives the movable member away from the blockage detection sensor, outputting a timely signal. This allows for rapid and accurate determination of whether the upper rollers of the material conveying roller groups corresponding to the driven member are lifted, thereby quickly and accurately determining whether there is a material blockage in the material conveying roller groups corresponding to the driven member, thereby improving the operational safety of the equipment.

[0020] 2) The stroke limiting mechanism of this utility model comprises several slots provided in the driven member, or several blocks fixed to the driven member. The driving member extends through the corresponding slots or is located below the corresponding blocks. This allows for the position of each driving member, and therefore the position of each upper roller, to be determined individually. This prevents the position changes of different material conveying roller groups in the same row from interfering with each other, effectively ensuring the practical effect of this utility model.

[0021] 3) The transmission mechanism of this utility model comprises a drive shaft rotatably mounted on the plate drying apparatus. A connecting plate with a long guide hole is fixedly connected to the inner end of the drive shaft, while a stopper shaft located within the long guide hole is fixedly connected to the driven member. As the driven member moves, the stopper shaft causes the connecting plate to swing, which in turn drives the drive shaft to rotate. This allows for the external mounting of the blockage detection sensor and smoothly drives the movable member away from the blockage detection sensor, further ensuring the practical effects of this utility model.

[0022] 4) The present invention has two blockage detection sensors. The movable member is equipped with two corresponding detection sections. These sensors are positioned one above the other. During the rotation of the movable member, the detection sections sequentially separate from the upper and lower detection sensors. This allows for continuous monitoring of the travel of the movable member, or driven member. When the detection section separates from the upper sensor, a preload warning is issued; when the detection section separates from the lower sensor, a severe blockage warning is issued.

DETAILED DESCRIPTION

[0027] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0028] Example 1

[0029] refer to Figure 1-2 , a plate blockage detection device for plate drying equipment, comprising:

[0030] Several material conveying roller groups 1 are arranged in a corresponding plate drying device 2 according to their height distribution, and are used to convey the plates. The material conveying roller groups 1 respectively include an upper roller 101 and a lower roller 102 arranged above and below.

[0031] A plurality of driving members 3 are respectively fixedly connected to the ends of the upper roller 101. Followers 4 are movably provided on the outside of the driving members 3. The follower 4 is provided with a stroke limiting mechanism 5 corresponding to the driving member 3. When the movement distance of any driving member 3 exceeds a set value, the driving member 4 contacts the stroke limiting mechanism 5 and drives the follower 4 to move through the stroke limiting mechanism 5.

[0032] The detection mechanism 6 includes a plate blockage detection sensor 601 arranged on the outside of the plate drying equipment 2, and a movable part 602 movably arranged at the detection end of the plate blockage detection sensor 601. The movable part 602 is connected to the driven part 4 through a corresponding transmission mechanism 7.

[0033] The present invention is provided with a driving member 3, a driven member 4, and a stroke limiting mechanism 5, enabling the present invention to be used in high-temperature environments. When the travel distance of any driving member 3 exceeds a set value, the driving member 3 contacts the stroke limiting mechanism 5 and drives the driven member 4 to move. As the driven member 4 moves, the transmission mechanism 7 drives the movable member 602 away from the blockage detection sensor 601 to output a signal in a timely manner. This allows for rapid and accurate determination of whether the upper roller 101 is lifted in the plurality of driving members 3 corresponding to the driven member 4, i.e., in the plurality of material conveying roller groups 1, thereby quickly and accurately determining whether there is a material blockage in the material conveying roller group 1 corresponding to the driven member 4, thereby improving the operational safety of the equipment.

[0034] The stroke limiting mechanism 5 comprises a plurality of slots provided on the driven member 4, and the end of the driving member 3 not connected to the upper roller 101 is passed through the corresponding slots. The driving member 3 is a shaft, and the driven member 4 is a long rod.

[0035] The transmission mechanism 7 includes a drive shaft 701 rotatably mounted on the plate drying device 2. The inner end of the drive shaft 701 is fixedly connected to a corresponding connecting plate 702. The end of the connecting plate 702 not connected to the drive shaft 701 is provided with a corresponding guide slot 8. The driven member 4 is fixedly connected to a limiting shaft 9 located within the guide slot 8. The movable member 602 is plate-shaped and fixedly connected to the outer end of the drive shaft 701.

[0036] As the follower 4 moves, the limiting shaft 701 drives the connecting plate 702 to swing, thereby driving the driving shaft 701 to rotate, thereby achieving: external installation of the blocking plate detection sensor 601, and smoothly driving the movable part 602 to leave the blocking plate detection sensor 601, so as to further ensure the practical effect of the present invention.

[0037] There are two blockage detection sensors 601, and the movable member 602 is equipped with two detection units corresponding to these sensors 601. The two blockage detection sensors 601 are positioned one above the other. During the rotation of the movable member 602, the detection units sequentially separate from the upper and lower detection sensors. This allows for continuous detection of the travel of the movable member 602, i.e., the driven member 4. When the detection unit separates from the upper detection sensor 601, a preload warning is issued; when the detection unit separates from the lower detection sensor 602, a severe blockage warning is issued.

[0038] Example 2

[0039] refer to Figure 3 The difference between this embodiment and the first embodiment is that the stroke limiting mechanism 5 includes a plurality of shift blocks fixedly connected to the driven member 4, the shift blocks face the driving member 3, and are respectively located on the upper side of the corresponding driving member 3.

[0040] The stroke limiting mechanism 5 of the present invention comprises a plurality of slots provided in the driven member 4, or a plurality of blocks fixed to the driven member. The driving member 3 extends through the corresponding slots or is located below the corresponding blocks. This allows for the position of each driving member 3, and therefore the position of each upper roller 101, to be determined individually. This prevents the position changes of different material conveying roller groups 1 in the same row from interfering with each other, thereby effectively ensuring the practical effects of the present invention.

[0041] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
