Description

Technical Field

[0001] The invention relates to the technical field of cork paper processing, in particular to a bark crushing device for producing and processing cork paper. Background Art

[0002] Cork paper is made of pure cork particles and elastic adhesives through stirring, compression, curing, slicing, trimming and other processes. The product is elastic and tough; it also has the characteristics of sound absorption, shock absorption, heat insulation, anti-static, insect and ant resistant, and flame retardant. Among them, bark is one of the essential raw materials for making cork paper.

[0003] The bark is usually in the form of flakes and is relatively large in size. When processing this type of bark, the first step is to break the bark into pieces, which facilitates subsequent processing.

[0004] Bark has low requirements for storage environment, so it is usually placed outdoors and easily wetted by rain. When wet bark needs to be processed, one method is to crush the wet bark and then dry or air dry the bark pieces, but this method takes a lot of time; the other method is to squeeze the bark pieces to squeeze out the moisture inside the bark.

[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] See also Figure 1 As shown, a bark crushing device for cork paper production and processing is provided, comprising a housing 100 and a rotating roller 104. The housing 100 is in the shape of a square tube that is connected from top to bottom. The upper part is used for feeding bark, and the lower part is used for discharging bark fragments. Figure 1 The state of the housing 100 in FIG. 1 is based on the state of the housing 100, and two horizontally arranged rotating shafts 101 are rotatably penetrated at opposite ends of the housing 100, and one end of the two rotating shafts 101 is provided with a transmission gear 102 for meshing the two, and one end of one of the rotating shafts 101 is connected to a motor 103 installed on the side wall of the housing 100. In addition, two rollers 104 are provided, and the two rollers 104 are fixedly sleeved on the outer ring of the rotating shaft 101 in an opposing manner. In this way, through the drive of the motor 103, the two transmission gears 102 realize relative rotation through the transmission gear 102, thereby driving the two rollers 104 to rotate relative to each other, so as to crush the bark entering the housing 100 into bark fragments.

[0024] like Figure 3As shown, the inside of the housing 100 is oppositely provided with a receiving plate 120 located below the rotating roller 104, and a distance d is left between the adjacent ends of the two receiving plates 120. Due to the existence of the distance d, the bark fragments on the top of the receiving plate 120 can fall through the distance d, so the portion corresponding to the distance d also forms a drop opening 121. Then, a resettable extrusion mechanism 130 is slidably provided at the top of the receiving plate 120, and a resettable discharge mechanism 140 is rotatably provided at the bottom of the receiving plate 120. Among them, a driven mechanism is provided between the extrusion mechanism 130 and the rotating shaft 101, which drives the extrusion mechanism 130 to move to the drop opening 121 through the rotating shaft 101; at least a part of the discharge mechanism 140 is located below the drop opening 121, and is used to open and close the drop opening 121. Under normal circumstances, the discharge mechanism 140 controls the drop port 121 to be in a closed state; when the bark fragments fall to the top of the receiving plate 120, the driven mechanism drives the squeezing mechanism 130 to move toward the drop port 121 to squeeze the bark fragments; when the squeezing mechanism 130 is reset, the discharge mechanism 140 controls the drop port 121 to be in an open state, so that the dehydrated bark fragments fall through the drop port 121.

[0025] Figure 3 The specific structure of the extrusion mechanism 130 is shown. As shown in the figure, the extrusion mechanism 130 includes a mounting plate 131 with an extrusion block 132 fixedly connected at one end and a reset spring 133 fixedly connected at the other end. The mounting plate 131 is slidably arranged on the top of the receiving plate 120, and the sliding direction of the mounting plate 131 is horizontal. Among them, the extrusion block 132 is arranged near the blanking port 121, and one end of the reset spring 133 is fixed to the inner wall of the shell 100. In this way, when the mounting plate 131 drives the extrusion block 132 to move toward the blanking port 121, the reset spring 133 will be stretched, thereby providing power for the subsequent reset of the mounting plate 131. At the same time, in order to prevent the mounting plate 131 from shaking during the movement, a round rod 134 that slides through the side wall of the shell 100 is fixedly arranged on one side of the mounting plate 131 near the reset spring 133.

[0026] like Figure 2 As shown, an installation cavity 105 is left between one end of the roller 104 and the inner wall of the housing 100, and the installation cavity 105 is used to provide a space for the driven mechanism to install and move; and a guard plate 106 fixed to the inner wall of the housing 100 is provided on the top of the installation cavity 105 to prevent bark from entering the installation cavity 105. Figure 4 and Figure 5 ,exist Figure 4 In the embodiment, the driven mechanism includes a rotating ring 110 located in the installation cavity 105, and an eccentric rod 111 eccentrically arranged on one side of the rotating ring 110. The rotating ring 110 is coaxially connected to the rotating shaft 101 in a reverse manner to drive the driven arm 150 described in detail below to move; the eccentric rod 111 is arranged close to the outer ring of the rotating ring 110. In addition, as Figure 5 As shown, the driven mechanism also includes a driven arm 150. Figure 5 In the embodiment shown, a downwardly recessed slide groove 151 is provided at the top of the driven arm 150, and the bottom end extends toward the mounting plate 131 and slides through the mounting plate 131; meanwhile, a connecting spring 152 is provided between one end of the driven arm 150 that slides through the mounting plate 131 and the side wall of the mounting plate 131 to elastically connect the two. When the connecting spring 152 is not subjected to external force, that is, in a normal state, the connecting spring 152 controls the slide groove 151 to separate from the motion path of the eccentric rod 111.

[0027] When the eccentric rod 111 drives the mounting plate 131 to move through the driven arm 150, the connecting spring 152 will be compressed. However, since the extrusion block 132 needs a large power to squeeze the bark pieces, it is easy to cause the connecting spring 152 to be over-compressed. Therefore, the present invention sets a straight rod toward the side wall of the mounting plate 131 at one end of the driven arm 150 close to the connecting spring 152. When the driven arm 150 needs to drive the mounting plate 131 to move, the driven arm 150 first slides on the side wall of the mounting plate 131, and then when the straight rod abuts against the side wall of the mounting plate 131, the driven arm 150 drives the mounting plate 131 to move through the straight rod.

[0028] The state of the rotating shaft 101 near the housing 100 is upward rotation. If the rotating ring 110 and the rotating shaft 101 rotate in the same direction, the eccentric rod 111 cannot drive the driven arm 150 to move toward the blanking port 121. Therefore, the rotating ring 110 and the rotating shaft 101 are coaxially reversely connected. Coaxial reverse connection means that the rotating ring 110 and the rotating shaft 101 are in a coaxial state, but rotate in opposite directions. Specifically, Figure 4 As shown, the inner ring of the rotating ring 110 and the outer ring of the rotating shaft 101 are both provided with tooth blocks, and a driven gear 112 meshing with the tooth blocks is provided between the inner ring of the rotating ring 110 and the outer ring of the rotating shaft 101. In this way, when the rotating shaft 101 rotates forward, the rotating shaft 101 drives the rotating ring 110 to rotate in the reverse direction through the driven gear 112. In addition, the side wall of the driven gear 112 is fixedly connected to a shaft rod 113 whose one end rotates on the inner wall of the housing 100, and the side wall of the rotating ring 110 is rotatably connected to a shaft tube 114 fixedly connected to the inner wall of the housing 100, so as to fix the driven gear 112 and the rotating ring 110.

[0029] like Figure 6As shown, the discharge mechanism 140 includes two fixed shafts 141 opposite to the bottom of the receiving plate 120, the ends of the fixed shafts 141 are fixedly connected to the side walls of the housing 100, the two ends of the fixed shaft 141 are rotatably provided with baffle plates 142 in a resettable manner, and the middle part is rotatably provided with a sensing plate 143 in a resettable manner. Among them, a connecting block 144 is provided between the two baffle plates 142 at the two ends to fix the two; and a drainage port is provided on the top of the baffle plate 142 to allow the squeezed water to be discharged through the drainage port. In addition, a control unit for controlling the opening and closing of the blanking port 121 is provided between the baffle plate 142 and the mounting plate 131; and a driving unit for driving the chute 151 to enter the movement path of the eccentric rod 111 is provided between the sensing plate 143 and the driven arm 150.

[0030] exist Figure 5-Figure 8 In the embodiment shown, the driving part includes a push rod 146 fixedly arranged at the bottom of the induction plate 143, and a wedge block 148 arranged to slide longitudinally through the receiving plate 120; wherein the bottom end of the push rod 146 is bent upward to the bottom of the wedge block 148, referring to Figure 8 The shape of the push rod 146 after bending is roughly semicircular. When the sensing plate 143 rotates downward, the sensing plate 143 pushes the wedge block 148 upward through the push rod 146. The inclined surface of the wedge block 148 is set at the top to Figure 8 In addition, the driving part further comprises an extension plate 153, one end of which is fixedly connected to the end of the driven arm 150, and the other end of which extends to the top of the wedge block 148. When the wedge block 148 moves upward, the extension plate 153 can be driven to move toward the mounting plate 131.

[0031] At the same time, when the wedge block 148 cannot move upward, the opening distance of the two induction plates 143 when they are rotated downward is smaller than the volume of the bark fragments, which can prevent the bark fragments from falling off. For specific conditions, refer to Figure 7 .

[0032] exist Figure 6 , Fig. 9 and Fig.10 In the illustrated embodiment, the control unit includes a fixing plate 145 fixedly arranged on one end of the material blocking plate 142 near the fixing shaft 141, one end of the fixing plate 145 is bent upward into the through slot inside the material receiving plate 120, and a bevel 147 is arranged on one side of the top of the fixing plate 145 near the fixing shaft 141. In addition, the control unit also includes a limit rod 135 fixedly arranged on one side of the mounting plate 131, the limit rod 135 is located at the top of the fixing plate 145, and the length of the limit rod 135 is not less than the moving distance when the squeezing block 132 clamps the bark fragments, that is, when the squeezing block 132 clamps the bark fragments, the limit rod 135 is detached from the top of the fixing plate 145.

[0033] In addition, a compression spring 149 is disposed at the bottom of the baffle plate 142 and the induction plate 143 , one end of which is fixedly connected to the inside of the housing 100 , so as to provide power for resetting the baffle plate 142 and the induction plate 143 .

[0034] Working principle: The bark passes through the top of the housing 100 and enters between the two rollers 104, where it is torn into pieces by the relative rotation of the two rollers 104. The pieces fall into the drop opening 121 by gravity, but are blocked by the baffle plate 142 and the induction plate 143, so that the pieces can only accumulate on the top of the baffle plate 142 and the induction plate 143.

[0035] As the number of bark fragments increases, the weight of the bark fragments also increases. At this time, the weight of the bark fragments overcomes the elastic force of the compression spring 149 at the bottom of the sensing plate 143, forcing the compression spring 149 to compress, thereby driving the sensing plate 143 to rotate downward. At this time, the sensing plate 143 drives one end of the push rod 146 to push the wedge block 148 upward. The wedge block 148 drives the extension plate 153 to move toward the mounting plate 131 through the inclined surface at the top. The extension plate 153 drives the driven arm 150 to move toward the eccentric rod 111, so that the chute 151 enters the movement path of the eccentric rod 111. In this way, the eccentric rod 111 can enter the chute 151 during the rotation process, and then drives the driven arm 150 to move through the chute 151. The driven arm 150 drives the mounting plate 131 and the extrusion block 132 to move. The extrusion block 132 moves toward the drop opening 121, thereby extruding the bark fragments at the drop opening 121.

[0036] When the squeezing block 132 starts squeezing the bark pieces, the squeezing block 132 clamps the bark pieces, and the weight of the bark pieces is not fully applied to the baffle plate 142 and the induction plate 143. At the same time, the limit rod 135 is separated from the top of the fixing plate 145. As the eccentric rod 111 is continuously driven, the squeezing block 132 continues to clamp the bark pieces, compressing and draining the bark pieces, and the squeezed water is first discharged through the drainage port at the top of the baffle plate 142. When the eccentric rod 111 rotates upward, the eccentric rod 111 can be separated from the slide 151, and the extrusion block 132 can be reset by the reset spring 133. In the process of resetting, the volume of the extruded bark fragments becomes smaller. Therefore, when the extrusion block 132 just separates from the bark fragments, the end of the limit rod 135 has not yet reset to the top of the fixed plate 145. At this time, the compressed bark fragments fall on the top of the baffle plate 142 and the induction plate 143, and the baffle plate 142 is pressed downward by gravity. When the baffle plate 142 rotates downward, the drop port 121 is opened, and the bark fragments on the top of the baffle plate 142 and the induction plate 143 fall. After the bark fragments fall. When the limit rod 135 is reset to the fixed plate 145, the limit rod 135 pushes the fixed plate 145 and the baffle plate 142 to reset through the bevel 147 (the baffle plate 142 can also be reset by the compression spring 149).

[0037] In addition, the top of the induction plate 143 is convexly arc-shaped to prevent bark fragments from accumulating on the top of the induction plate 143. When the bark fragments on the top of the induction plate 143 decrease, the compression spring 149 drives the induction plate 143 to move upward and reset through elastic force. At this time, the induction plate 143 resets and stops pushing the wedge block 148, so that the wedge block 148 stops driving the reset extension plate 153. At this time, the connecting spring 152 drives the slide slot 151 away from the movement path of the eccentric rod 111.

[0038] It is worth noting that a filter screen is preferably provided at the bottom of the crushing device of the present invention, and the filter screen is used to intercept the bark fragments after being squeezed to prevent the bark fragments from contacting the squeezed water again.

[0039] That is, by arranging two relatively movable squeezing blocks 132 at the bottom of the roller 104, after the bark fragments are accumulated for a period of time, the power of the crushing device can be used to squeeze and drain the bark fragments, thereby achieving rapid squeezing after the bark is crushed.

[0040] Moreover, Figure 3 , Fig.11 as well as Fig.12As shown, two symmetrical guide plates 160 are rotatably arranged below and between the two rollers 104 in the housing 100, and a limit block is arranged at the bottom of the guide plate 160 on the inner wall of the housing 100 to prevent the guide plate 160 from rotating downward. A plurality of convex plates 161 are fixedly arranged at the bottom of the guide plate 160, and gaps are arranged between the plurality of convex plates 161. The top of the extrusion block 132 is in an inclined state, with a lower position near the blanking port 121 and a higher position at the other end.

[0041] Working principle: when the bark fragments fall from between the two rollers 104, some of the bark fragments fall on the top of the guide plate 160 and are intercepted by the convex plate 161, and the other part of the bark fragments pass through the gap between the two guide plates 160 and the bottom of the guide plate 160 and fall on the top of the receiving plate 120, the top of the baffle plate 142 and the top of the induction plate 143. When the extrusion block 132 moves toward the drop port 121, the extrusion block 132 pushes the guide plate 160 to rotate upward through the inclined surface at the top, so that the guide plate 160 approaches the roller 104, so that the roller 104 contacts the bark fragments on the surface of the guide plate 160, and the bark fragments are further crushed.

[0042] It can be seen that, by cooperating with the extrusion block 132, the extrusion block 132 can not only extrude the bark fragments during movement, but also further crush a part of the bark fragments, thereby reducing the volume of the bark fragments and facilitating subsequent crushing operations.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention.
