Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable processing technology, and in particular to a tunnel dryer. Background Technology

[0002] The existing Chinese patent application number 202020261814.1 discloses a tunnel-type dryer, including a frame, a drying box placed on the frame, and a conveying device placed on the frame. The conveying device also includes a conveyor belt and several rotating shafts. The conveying device is equipped with a cleaning device placed on the frame. The cleaning device includes an upper cleaning component that is rectangular and placed on the inner side of the conveyor belt and a lower cleaning component that is rectangular and placed on the outer side of the conveyor belt. The upper cleaning component is equipped with an upper brush, and the lower cleaning component is equipped with a lower brush. The upper cleaning component is equipped with several evenly arranged upper water spray holes, and the lower cleaning component is equipped with several evenly arranged lower water spray holes.

[0003] While the aforementioned technology cleans the conveyor belt by installing water spray components, the lack of belt correction components makes the belt prone to uneven wear after prolonged operation, resulting in a shorter lifespan and increased equipment wear, thus raising operating costs. Therefore, to address these technical shortcomings, we propose a tunnel-type dryer. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tunnel-type dryer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tunnel-type dryer includes a base plate. A conveyor belt is mounted on the upper surface of the base plate via a support plate. The dryer body is located on the upper side of the support plate. Upper telescopic components are mounted on both ends of the side of the support plate. A lower telescopic component is located on the upper surface of the base plate corresponding to the middle of the conveyor belt. Both the upper and lower telescopic components have a linkage plate hinged to their output ends. A mounting seat is hinged to the other end of the linkage plate. A mounting rod is provided on the surface of the conveyor belt corresponding to the mounting seat. The outer ring of the mounting rod has a symmetrical mounting groove. A wiping strip is provided in the mounting groove. The mounting rod contacts the surface of the conveyor belt through the wiping strip. A locking component is provided between one end of the mounting rod and the mounting seat.

[0007] Preferably, the locking assembly includes a worm gear and a worm, with the worm gear mounted at the end of the mounting rod and the worm mounted on the surface of an adjacent mounting base and meshing with the worm gear.

[0008] Preferably, a pointer is installed at the end of the mounting rod away from the locking component, and the surface of the adjacent mounting base has corresponding scale markings for the pointer.

[0009] Preferably, the mounting groove of the mounting roller is provided with a limiting rod, and the side of the wiping strip away from the conveyor belt is inserted into the mounting groove through the limiting rod.

[0010] Preferably, one end of the mounting groove extends to the end of the mounting rod, and a baffle plate is provided on the inner side of the mounting base corresponding to the mounting groove. The baffle plate is installed on the side of the mounting base near the conveyor belt.

[0011] Preferably, the mounting rollers are located on the inner and outer sides of the conveyor belt, and a corresponding correction sensor is installed at one end of the support plate corresponding to the conveyor belt.

[0012] Preferably, the mounting base is connected to the mounting roller via a bearing, and the rotation direction of the conveyor belt and the rotation direction of the linkage plate are cross-shaped.

[0013] The tunnel-type dryer proposed in this utility model has the following advantages:

[0014] In this invention, several mounting rollers are provided on both sides of the lower layer of the conveyor belt, and mounting grooves are symmetrically provided on the outer ring of the mounting rollers. Wiping strips are installed in the mounting grooves closest to the conveyor belt. When the conveyor belt is running, each wiping strip scrapes against the inner and outer surfaces of the conveyor belt, thereby cleaning the residual debris on the surface of the conveyor belt. Disinfectant liquid can also be added to the wiping strips as needed, so that the surface of the conveyor belt can be disinfected by the disinfectant liquid when the wiping strips scrape against the surface of the conveyor belt. The old wiping strips can be swapped with the new wiping strips by rotating the mounting rollers, thereby completing the replacement of the wiping strips. At the same time, the mounting rollers can be tilted by the telescopic component, thereby achieving a correction effect on the conveyor belt. In summary, this solution, through the cooperation of various components, can not only clean stubborn stains on the conveyor belt, but also facilitate the replacement of wiping strips and provide a correction effect on the conveyor belt.

[0015] In this invention, the locking assembly consists of a worm gear and a worm, which not only provides a self-locking effect but also amplifies torque, making it easier for personnel to rotate the installation roller and thus saving physical exertion. The pointer and scale markings allow the pointer to point to different marks as the installation roller rotates, enabling personnel to determine whether the installation roller rotates on its own without conscious effort by observing the angle of the pointer. This ensures the stability of the installation roller during use and prevents the side without the wiping strip from contacting the conveyor belt due to random rotation. The baffle plate prevents the wiping strip from separating from the installation groove, thus avoiding the phenomenon of the wiping strip separating from the installation groove when the conveyor belt is running.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-4 A tunnel-type dryer includes a base plate 1. A conveyor belt 3 is mounted on the upper surface of the base plate 1 via a support plate 2. The dryer body 4 is located on the upper side of the support plate 2. Upper telescopic components 5 are mounted on both ends of the side of the support plate 2. A lower telescopic component 12 is located on the upper surface of the base plate 1 corresponding to the middle of the conveyor belt 3. The output ends of the upper telescopic component 5 and the lower telescopic component 12 are hinged to a linkage plate 6. The other end of the linkage plate 6 is hinged to a mounting seat 7. A mounting rod 8 is provided on the surface of the conveyor belt 3 corresponding to the mounting seat 7. The outer ring of the mounting rod 8 is symmetrically provided with a mounting groove. A wiping strip 9 is provided in the mounting groove. The mounting rod 8 contacts the surface of the conveyor belt 3 through the wiping strip 9. A locking component is provided between one end of the mounting rod 8 and the mounting seat 7.

[0025] Example 2

[0026] Reference Figure 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0027] The locking assembly includes a worm gear 10 and a worm 11. The worm gear 10 is installed at the end of the mounting rod 8, and the worm 11 is installed on the surface of the adjacent mounting seat 7 and meshes with the worm gear 10. Because the locking assembly consists of the worm gear 10 and the worm 11, it not only has a self-locking effect but also a torque amplification effect, making it easier for personnel to rotate the mounting rod 8, thus saving physical exertion. A pointer 13 is installed at the end of the mounting rod 8 away from the locking assembly, and the surface of the adjacent mounting seat 7 has corresponding scale markings for the pointer 13. The pointer 13 and the scale markings... The grooved design allows the pointer 13 to point to different scales when the installation roller 8 rotates. This allows personnel to determine whether the installation roller 8 rotates automatically without manual force by observing the angle pointed to by the pointer 13, thus ensuring the stability of the installation roller 8 during use and preventing the side without the wiping strip 9 from contacting the conveyor belt 3 due to random rotation. A limiting rod 14 is provided in the installation groove of the installation roller 8. The side of the wiping strip 9 furthest from the conveyor belt 3 is inserted into the installation groove via the limiting rod 14. The limiting rod 14 ensures a more secure and stable connection between the wiping strip 9 and the installation roller 8.

[0028] One end of the mounting groove extends to the end of the mounting roller 8. A baffle plate 15 is provided on the inner side of the mounting base 7 corresponding to the mounting groove. The baffle plate 15 is installed on the side of the mounting base 7 close to the conveyor belt 3. The baffle plate 15 prevents the wiping strip 9 from separating from the mounting groove, thus avoiding the phenomenon of the wiping strip 9 separating from the mounting groove when the conveyor belt 3 is running. The mounting roller 8 is located on the inner and outer sides of the conveyor belt 3 respectively. One end of the support plate 2 is equipped with a matching correction sensor 16 corresponding to the conveyor belt 3. The correction sensor 16 facilitates the monitoring of the position of the conveyor belt 3, thereby preventing the conveyor belt 3 from running off-center and causing uneven wear, which affects its service life. The mounting base 7 is connected to the mounting roller 8 through a bearing. The rotation direction of the conveyor belt 3 and the rotation direction of the linkage plate 6 are cross-shaped.

[0029] Operating principle and advantages: In use, materials are transported via conveyor belt 3. Since the upper side of the support plate 2 is equipped with a dryer body 4, the elongated dryer body 4 dries the materials passing beneath the conveyor belt 3, thus forming a drying tunnel. This effectively dries the materials transported by the conveyor belt 3. During this process, several mounting rollers 8 are provided on both sides of the lower layer of the conveyor belt 3. The outer ring of each mounting roller 8 has symmetrical mounting grooves, with wiping strips 9 installed in the grooves closest to the conveyor belt 3. When the conveyor belt 3 operates, each wiping strip 9 scrapes against the inner and outer surfaces of the conveyor belt 3, cleaning any remaining debris. Disinfectant liquid can also be added to the wiping strips 9 as needed, disinfecting the surface of the conveyor belt 3 while the wiping strips 9 scrape against it.

[0030] Furthermore, in the above process, since the mounting roller 8 can rotate, when the wiping strip 9 needs to be replaced, the operator first installs the new wiping strip 9 in another mounting slot on the mounting roller 8, and then rotates the mounting roller 8. As the mounting roller 8 rotates, the old wiping strip 9 and the new wiping strip 9 are interchanged, thus completing the replacement of the wiping strip 9. The mounting seat 7 at the end of the mounting roller 8 is connected to the upper telescopic component 5 and the lower telescopic component 12 through the linkage plate 6, and the two ends of the linkage plate 6 are hinged. That is, when the output end of one of the telescopic components retracts, the mounting roller 8 connected to this telescopic component can be tilted, thereby achieving a correction effect on the conveyor belt 3. In summary, this solution, through the cooperation of various components, can not only clean stubborn stains on the conveyor belt 3, but also facilitate the replacement of the wiping strip 9 and provide a correction effect on the conveyor belt 3.

[0031] It should be further explained that, since the locking assembly consists of a worm gear 10 and a worm 11, it not only has a self-locking effect but also a torque amplification effect, making it easier for personnel to rotate the installation roller 8, thus saving physical exertion. The pointer 13 and the scale markings ensure that the pointer 13 points to different marks when the installation roller 8 rotates. Thus, personnel can determine whether the installation roller 8 rotates on its own without active force by observing the angle pointed to by the pointer 13, ensuring the stability of the installation roller 8 during use and preventing the side without the wiping strip 9 from contacting the conveyor belt 3 due to random rotation. The baffle plate 15 prevents the wiping strip 9 from separating from the installation groove, thus avoiding the phenomenon of the wiping strip 9 separating from the installation groove when the conveyor belt 3 is running. The alignment sensor 16 facilitates the monitoring of the position of the conveyor belt 3, thereby preventing the conveyor belt 3 from running off-center and causing uneven wear, which affects its service life.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
