Description

Technical Field

[0001] The present invention belongs to the technical field of processing of pulp molded products, and specifically refers to a drying device for pulp molded products. Background Art

[0002] Pulp molded products are an environmentally friendly material product made from raw materials such as waste paper or wood pulp through mechanical processing and forming techniques. Its production process mainly includes steps such as pulp preparation, mold forming, drying, and trimming.

[0003] Natural drying refers to placing wet pulp molded products in a ventilated and dry environment and using the heat and wind in natural air to dry the products. Although sunlight helps to accelerate drying, direct strong light may cause the surface of the products to dry too quickly, while the internal moisture is difficult to evaporate, resulting in residual moisture inside the products and affecting the quality.

[0004] According to different times, the angle between the sun and the ground plane is different, which in turn leads to different radiation intensities of the pulp molded products under sunlight. If the pulp molded products are placed in a fixed position under the sun, it will cause local drying of the pulp molded products to be faster or drying to be too fast. Summary of the Invention

[0005] In view of the above situation, to overcome the defects of the prior art, the present invention provides a drying device for pulp molded products, which at least partially solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: The present invention provides a drying device for pulp molded products, including a placement component and a placement rack; The placement component is arranged on the upper part of the placement rack. The placement component includes multiple groups of upper components and multiple groups of lower components. Multiple groups of the upper components are arranged on the upper part of multiple groups of the lower components, and multiple groups of the upper components and multiple groups of the lower components are arranged in a mirror image; The placement rack is used to support the placement component. The placement rack includes two groups of lower cross beams and two groups of upper cross beams. One group of the lower cross beams is arranged below the upper cross beam, and the setting height of this group of lower cross beams is lower than the setting height of the upper cross beam.

[0007] Furthermore, multiple groups of the upper components and multiple groups of the lower components each include a drying component, a front placement block, a front rotating connecting rod, a lower rotating rod, a rear placement block, an upper rotating rod, a front linkage rod, a movable module, a rotating connecting rod, and an operating connecting rod. The front placement block is fixedly connected to the upper part of the lower cross beam.

[0008] Further, the front rotating link is rotatably connected to the rear of the front placing block, the lower rotating rod is rotatably connected to the rear of the front rotating link, the rear placing block is fixedly connected to the upper part of the upper cross beam, the upper rotating rod is rotatably connected to the front of the rear placing block, the front linkage rod is fixedly connected to the front of the upper rotating rod, the movable module is fixedly connected to the front of the front linkage rod, the rotating link is arranged in the middle of the movable module, the operating link is arranged in the middle of the front rotating link, and the drying assembly is movably connected to the middle of the rotating link.

[0009] Further, the drying assembly includes a flat plate, an inclined plate, a spring, a movable plate, a driving plate, a driven plate, a rotating lifting module, a placing plate, a sliding rod, a collar and a storage area, and the flat plate is fixedly connected to the upper part of the lower cross beam.

[0010] Further, the inclined plate is fixedly connected to the upper part of the flat plate, the spring is fixedly connected to the rear of the inclined plate, the movable plate is fixedly connected to the rear of the spring, the movable plate is rotatably connected to the driving plate, the driven plate is rotatably connected to the driving plate, the driven plate is fixedly connected to the rotating lifting module, the rotating lifting module is rotatably connected to the rotating link, the placing plate is fixedly connected to the rotating lifting module, a plurality of groups of sliding rods are fixedly connected to the upper part of the placing plate, a collar is movably connected to the outside of the plurality of groups of sliding rods, and a storage area is arranged in the middle of the collar.

[0011] Further, each group of upper components and each group of lower components are connected by an operating link and a rotating link, and the front of the lower rotating rod is rotatably connected to the upper rotating rod.

[0012] Further, there is a certain angle between the inclined plate and the flat plate, and the range of this angle is 100° to 120°.

[0013] Further, a plurality of groups of first support beams are fixedly connected between the lower cross beam at the high position and the upper cross beam at the low position, and a plurality of groups of second cross beams are fixedly connected between the lower cross beam at the low position and the upper cross beam at the high position.

[0014] Further, a first support foot is fixedly connected to the lower part of the lower cross beam at the lowest position, and a second support foot is fixedly connected to the lower part of the upper cross beam at the lowest position.

[0015] The beneficial effects obtained by the present invention with the above structure are as follows: (1) The drying assembly is movably connected to the middle of the rotating link and can rotate on the rotating link. By applying an external force to make it rotate, the relatively wet part of the pulp molded product can be oriented towards or away from direct sunlight, and the relatively dry part of the pulp molded product can be oriented towards direct sunlight, preventing the surface from drying too quickly while the internal moisture is difficult to evaporate, thus affecting the quality. (2)When the solar altitude angle is small, after the drying component is driven and moved by the operating link, the angle between the drying component and the ground plane will change. When taking the ground plane as a reference, if the solar altitude angle remains unchanged, changing the angle between the drying component and the ground plane means changing the incident angle between the drying component and sunlight. When changing this angle, the radiation intensity of the pulp molded product exposed to sunlight can be changed. Furthermore, according to the humidity of the pulp molded product, the side with higher humidity can receive sufficient sunlight to accelerate its drying process. Description of the Drawings

[0021] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides a drying device for pulp molding products, including a placement component 1 and a placement rack 2; The placement component 1 is arranged on the upper part of the placement rack 2. The placement component 1 includes multiple groups of upper components 11 and multiple groups of lower components 12. The multiple groups of upper components 11 are arranged on the upper part of the multiple groups of lower components 12, and the multiple groups of upper components 11 and the multiple groups of lower components 12 are arranged in a mirror image. The placement rack 2 is used to support the placement component 1. The placement rack 2 includes two groups of lower cross beams 201 and two groups of upper cross beams 202. One group of the lower cross beams 201 is arranged on the lower part of the upper cross beam 202, and the set height of this group of lower cross beams 201 is lower than the set height of the upper cross beam 202.

[0022] As Figure 4 and Figure 5 shown, the multiple groups of upper components 11 and the multiple groups of lower components 12 both include drying components 101, front placement blocks 102, front rotating connecting rods 103, lower rotating rods 104, rear placement blocks 105, upper rotating rods 106, front linkage rods 107, movable modules 108, rotating connecting rods 109, and operating connecting rods 110. The front placement blocks 102 are fixedly connected to the upper part of the lower cross beams 201.

[0023] As Figure 4 and Figure 5As shown, the front rotating link 103 is rotatably connected to the rear of the front placing block 102, the lower rotating rod 104 is rotatably connected to the rear of the front rotating link 103, the rear placing block 105 is fixedly connected to the upper part of the upper cross beam 202, the upper rotating rod 106 is rotatably connected to the front of the rear placing block 105, the front linkage rod 107 is fixedly connected to the front of the upper rotating rod 106, the movable module 108 is fixedly connected to the front of the front linkage rod 107, the rotating link 109 is arranged in the middle of the movable module 108, the operating link 110 is arranged in the middle of the front rotating link 103, and the drying component 101 is movably connected to the middle of the rotating link 109.

[0024] As Figure 4 and Figure 5 shown, between each group of the upper components 11 and each group of the lower components 12, they are all connected by the operating link 110 and the rotating link 109, and the front of the lower rotating rod 104 is rotatably connected to the upper rotating rod 106.

[0025] In this embodiment, first, since the placing component 1 includes multiple groups of upper components 11 and multiple groups of lower components 12, and between each group of upper components 11 and each group of lower components 12, they are all connected by the operating link 110 and the rotating link 109, and because the number of multiple groups of upper components 11 and multiple groups of lower components 12 on the placing rack 2 is a fixed value, thus for the outermost upper component 11 and the lower component 12, the operating link 110 and the rotating link 109 thereon are not connected to other parts.

[0026] And if at this time the outermost operating link 110 is manually operated, then through the operating link 110, the upper component 11 and the lower component 12 of this group can be moved. After the upper component 11 and the lower component 12 of this group move, then through the operating link 110 and the rotating link 109 connected thereto, the remaining upper components 11 and lower components 12 are driven to move, and the movement trajectory is as follows.

[0027] First, manually move the operating link 110. The operating link 110 is arranged in the middle of the front rotating link 103. When the operating link 110 moves, it will drive the front rotating link 103 to move. The front rotating link 103 is rotatably connected to the rear of the front placing block 102, and the front placing block 102 is fixedly connected to the upper part of the lower cross beam 201. At this time, the front placing block 102 is in a fixed and static state and cannot be moved by an external force. Then the movement trajectory of the front rotating link 103 is a circle with the front placing block 102 as the center.

[0028] At this time, the lower rotating rod 104 is rotatably connected to the rear of the front rotating link 103. After the front rotating link 103 rotates with the front placing block 102 as the center, the lower rotating rod 104 will also rotate with the front placing block 102 as the center under the drive of the front rotating link 103.

[0029] At this time, the front of the lower rotating rod 104 is rotatably connected to the upper rotating rod 106. When the lower rotating rod 104 moves, it will also drive the upper rotating rod 106 to move. The upper rotating rod 106 is rotatably connected to the front of the rear placing block 105, and the rear placing block 105 is fixedly connected to the upper part of the upper cross beam 202. At this time, the rear placing block 105 is in a stationary state, and the movement trajectory of the upper rotating rod 106 is a circular trajectory with the rear placing block 105 as the center.

[0030] Since the front linkage rod 107 is fixedly connected to the front of the upper rotating rod 106, after the upper rotating rod 106 rotates with the rear placing block 105 as the center, the front linkage rod 107 will also move accordingly, and the movable module 108 connected to the front linkage rod 107 will also move accordingly. At this time, the rotating link 109 is arranged in the middle of the movable module 108. When the movable module 108 moves, the rotating link 109 will move following the movable module 108.

[0031] At this time, the drying assembly 101 is movably connected to the middle of the rotating link 109. When the rotating link 109 moves, the drying assembly 101 will move following the rotating link 109. Since the drying assembly 101 is mainly used to place pulp molded products, the angle between the drying assembly 101 and the ground plane can be adjusted according to the sunlight intensity at this time, so as to adjust the incident angle of sunlight.

[0032] First of all, the solar altitude angle refers to the angle between the sun's rays and the ground horizontal plane. When the solar altitude angle is 90 degrees, the sun shines directly on the ground and the radiation intensity is the largest. Although the sunlight at this time helps to accelerate drying, the direct strong light may cause the surface of the product to dry too quickly, and the internal moisture is difficult to evaporate, resulting in residual moisture inside the product and affecting the quality. At this time, the orientation of the pulp molded products on the drying assembly 101 can be adjusted by manually operating the link 110.

[0033] At this time, the drying assembly 101 is movably connected to the middle of the rotating link 109, so it can rotate on the rotating link 109. At this time, by applying an external force to make it rotate, the relatively wet part of the pulp molded product can be oriented away from the direct sunlight, and the relatively dry part of the pulp molded product can be oriented towards the direct sunlight, preventing its surface from drying too quickly and the internal moisture from being difficult to evaporate, thus affecting the quality.

[0034] When the solar altitude angle is relatively small, after the drying component 101 is driven and moved by the operating link 110, the angle between the drying component 101 and the ground plane will change. When taking the ground plane as a reference, if the solar altitude angle remains unchanged, changing the angle between the drying component 101 and the ground plane is equivalent to changing the incident angle between the drying component 101 and sunlight. When changing this angle, the radiation intensity of the pulp molded product irradiated by the sun can be changed. Furthermore, according to the humidity of the pulp molded product, the side with higher humidity can receive sufficient sunlight to accelerate its drying process.

[0035] As Figure 6 and Figure 7 shown, the drying component 101 includes a flat plate 1011, an inclined plate 1012, a spring 1013, a movable plate 1014, a driving plate 1015, a driven plate 1016, a rotating lifting module 1017, a placing plate 1018, a sliding rod 1019, a collar 10110, and a storage area 10111. The flat plate 1011 is fixedly connected to the upper part of the lower cross beam 201.

[0036] As Figure 6 and Figure 7 shown, the inclined plate 1012 is fixedly connected to the upper part of the flat plate 1011. The spring 1013 is fixedly connected to the rear part of the inclined plate 1012. The rear part of the spring 1013 is fixedly connected with a movable plate 1014. The movable plate 1014 is rotatably connected to the driving plate 1015. The driven plate 1016 is rotatably connected to the driving plate 1015. The driven plate 1016 is fixedly connected to the rotating lifting module 1017. The rotating lifting module 1017 is rotatably connected to the rotating link 109. The placing plate 1018 is fixedly connected to the rotating lifting module 1017. A plurality of sliding rods 1019 are fixedly connected to the upper part of the placing plate 1018. A collar 10110 is movably connected to the outside of the plurality of sliding rods 1019. A storage area 10111 is provided in the middle of the collar 10110.

[0037] As Figure 6 and Figure 7 shown, there is a certain angle between the inclined plate 1012 and the flat plate 1011, and the range of this angle is 100° to 120°.

[0038] In this embodiment, when the rotating link 109 moves, the rotating lifting module 1017 will follow the movement of the rotating link 109. At this time, the rotating link 109 makes a circular motion and gradually rises, and the movement trajectory of the rotating lifting module 1017 is the same as that of the rotating link 109. The driven plate 1016 is fixedly connected to the rotating lifting module 1017, so that the driven plate 1016 and the rotating lifting module 1017 move together.

[0039] Subsequently, the flat plate 1011 is fixedly connected to the upper part of the lower cross beam 201, and the inclined plate 1012 is fixedly connected to the upper part of the flat plate 1011. At this time, it can be determined that the flat plate 1011 and the inclined plate 1012 are in a static state. The front part of the inclined plate 1012 is connected with a spring 1013, and the rear part of the spring 1013 is fixedly connected with a movable plate 1014. The movable plate 1014 is rotatably connected with the driving plate 1015.

[0040] With the rise of the driven plate 1016, the overall length of the driving plate 1015 does not change. Then, the static flat plate 1011 and the inclined plate 1012 will fix the spring 1013, so that the spring 1013 fixes the movable plate 1014 through elastic tension, and the movable plate 1014 will pull the driving plate 1015, thereby driving the driving plate 1015 to drive the rotating lifting module 1017 to rotate on the rotating link 109.

[0041] After the rotating lifting module 1017 rotates, the placing plate 1018 thereon will follow the rotation. There are two sets of storage areas 10111 on the placing plate 1018 for placing pulp molded products. These two sets of storage areas 10111 can place pulp molded products with different drying degrees, and the entire drying and airing assembly 101 can be rotated to change the incident angle of sunlight with respect to the pulp molded products with different drying degrees.

[0042] As Figure 1 and Figure 2 shown, a plurality of first support beams 203 are fixedly connected between the lower cross beam 201 at a high position and the upper cross beam 202 at a low position, and a plurality of second cross beams 204 are fixedly connected between the lower cross beam 201 at a low position and the upper cross beam 202 at a high position.

[0043] As Figure 1 and Figure 2 shown, a first support leg 205 is fixedly connected to the lower part of the lower cross beam 201 at the lowest position, and a second support leg 206 is fixedly connected to the lower part of the upper cross beam 202 at the lowest position.

[0044] In this embodiment, both the first support beams 203 and the second cross beams 204 are used to process the placement rack 2, so that the placement rack 2 will not tip over due to placing too many pulp molded products with a large water content.

[0045] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

[0047] The above description of the present invention and its embodiments is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
