Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a fixing component of a leather retaining member and a material dropping hopper thereof. Background Art

[0002] The SQ123 shredder is the main equipment for making tobacco threads in the tobacco industry. Its main function is to shred tobacco. During the production process, the shredded tobacco processed by the shredder falls into the vibrating conveyor through the drop port, and is then transported to the downstream process through the vibrating conveyor. In order to prevent the shredded tobacco from overflowing and the ash generated during the shredding process from falling to the outside of the vibrating conveyor, the drop port of the drop hopper is surrounded by a baffle. Since the shredded tobacco will produce smoke oil when it is squeezed through the knife gate, during the production process, the shredded tobacco "sprayed" by the knife gate comes into contact with the baffle, and a large amount of "smoke oil" sticks to the baffle. If the smoke oil stuck to the baffle is not handled in time, it will become thicker and thicker, and it is easy to fall off and fall into the finished tobacco, which poses a quality risk. In order to ensure product quality, operators need to clean and wipe the baffle every day.

[0003] At present, the SQ123 type wire cutting machine adopts an integrated drop hopper. The upper part of the baffle is fixed on the drop opening fixing frame of the drop hopper, and the lower part surrounds the drop opening. When cleaning the baffle, the following problems exist:

[0004] First, the baffle is very difficult to maintain because it is soft and has no support, and the entire blanking port is small and closed. It takes about 40 minutes to clean the baffle thoroughly every day. After cleaning the baffle, the sewage that falls on the vibrating conveyor still needs to be cleaned manually, and it takes about 50 minutes to complete the entire cleaning work. The entire maintenance process is very labor-intensive, time-consuming, and labor-intensive, which does not meet the requirements of lean production.

[0005] Secondly, since the SQ123 shredder is structurally designed with an integrated knife roller, the knife roller and knife door can only slide horizontally in the forward and backward directions during maintenance, and the distance between them after separation is too small. During cleaning and maintenance, personnel are limited in space and can only stand on the vibrating conveyor and lean inward. Their hands and bodies are very close to the knife roller, and they are easily cut by the knife door and both sides of the knife roller. At the same time, the blanking port is made of stainless steel with many dead corners and sharp angles, which can easily cut hands and cause scratches. Therefore, there are major safety hazards when operators clean the skin barrier, and they cannot quickly clean the blanking port.

[0006] At present, there is no good solution in the industry for how to quickly clean the retaining skin at the blanking port of the SQ123 type wire cutting machine. Therefore, it is urgent to design a blanking port that can safely and quickly clean the retaining skin. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0029] In the description of the present invention, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to". The terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] The utility model provides a fixing assembly 100 for a barrier skin 300, such as Figure 1 As shown, it includes a connecting frame 11 and a fixed frame 12, the connecting frame 11 includes a first connecting frame 111 and a second connecting frame 112 arranged at one end of the first connecting frame 111, the fixed frame 12 includes a third connecting frame 121 and a fourth connecting frame 122 arranged at one end of the third connecting frame 121; the first connecting frame 111 is adapted to the blanking port fixing frame 21, and is used to be sleeved on the blanking port fixing frame 21; the second connecting frame 112 includes two fixed parts, the third connecting frame 121 includes two movable parts respectively slidably connected to the two fixed parts; the fourth connecting frame 122 is used to fix the baffle 300.

[0031] Specifically, the first connection frame 111 is formed by enclosing with the first baffle to form a frame adapted to the blanking port fixing frame 21. For example, when the blanking port fixing frame 21 is a rectangular frame, the first baffle encloses to form a rectangular frame; when the blanking port fixing frame 21 is cylindrical, the first baffle encloses to form a cylindrical frame. In order to facilitate the sliding fit connection of the third connection frame 121 to the second connection frame 112, the second connection frame 112 can be provided with fixing components on two opposite second baffles, and the third connection frame 121 can be provided with movable components on two opposite third baffles. Insert the two movable components into the two fixing components respectively, and the movable components can slide along the fixing components. For example, one of the second baffle and the third baffle is provided with a chute 13, and the other is provided with a slider 14. Preferably, for smooth sliding, the two fixing components are arranged parallel and opposite to each other, and the two movable components are arranged parallel and opposite to each other. The connection frame 11 and the fixed frame 12 can be made of materials such as white steel or stainless steel, which can prevent corrosion and rust and extend the service life.

[0032] In order not to affect the falling of materials and avoid blocking the materials, the first connection frame 111 is sleeved outside the blanking port fixing frame 21; the second connection frame 112 and the third connection frame 121 extend outwards to form a flange structure; the inner wall of the material channel of the third connection frame 121 is flush with or slightly larger than the inner wall of the material channel of the first connection frame 111 to prevent the third connection frame 121 from blocking the materials. During operation, the operator can hold the flange part of the third connection frame 121, which is convenient for aligning the movable component with the fixed component and for moving the third connection frame 121. The blanking port fixing frame 21 is arranged in the middle of the slicing machine body. In order to facilitate the alignment of the movable component with the fixed component, the front end of the second connection frame 112 can be extended to the outside of the machine body, and the fixed component is extended to the outside of the machine body accordingly. The operator can connect the movable component to the fixed component outside the machine body, which is more convenient for operation. After the first baffle is extended accordingly, it encloses to form a first connection frame 111 in the shape of a Chinese character "ri". The rear rectangular frame forms a material channel and is sleeved outside the blanking port fixing frame 21. The front rectangular frame can increase the connection strength between the first connection frame 111 and the second connection frame 112.

[0033] When in use, the first connection frame 111 is sleeved on the blanking port fixed frame 21, and the baffle 300 is installed on the fourth connection frame 122. By pushing the movable part along the fixed part, the third connection frame 121 can be easily and quickly pushed into the second connection frame 112, so that the fixed frame 12 is connected to the connection frame 11, and the material channels of the blanking port, the first connection frame 111, the second connection frame 112, the third connection frame 121 and the fourth connection frame 122 are connected in sequence to form a blanking channel, so that the fixed frame 12 with the baffle 300 installed is connected to the blanking port. When the baffle 300 is working and the material falls into the vibrating conveyor for transportation through the blanking channel, the baffle 300 blocks the falling material to prevent the tobacco from overflowing. After production is completed, the movable parts are pulled out along the fixed parts, and the third connecting frame 121 can be pulled out of the second connecting frame 112 conveniently and quickly, and the fixed frame 12 is separated from the connecting frame 11, thereby separating the baffle 300 from the blanking port. The baffle 300 can be moved to other locations for blowing, and then taken to the water pool for cleaning, thereby realizing off-site cleaning of the baffle 300.

[0034] It used to take operators about 50 minutes to wipe the drop port and the baffle 300 every day, and operators often cut their hands during the cleaning process. After installing the fixing component 100 and realizing the off-site cleaning of the baffle 300, the cleaning time was reduced to about 10 minutes, which greatly reduced the maintenance time and labor intensity of personnel. At the same time, operators no longer cut their hands or got scratched during the cleaning and maintenance process, reducing safety risks.

[0035] The extending direction of the fixed parts and the movable parts, that is, the direction in which the operator pushes and pulls the fixed frame 12, can be set according to the on-site conditions, preferably to facilitate the operation of the operator.

[0036] In one embodiment, Figure 2 As shown, the fixed component is configured as a chute 13, and the movable component is configured as a slider 14. Specifically, the chute 13 is configured on two second baffles that are relatively arranged on the second connecting frame 112, and the openings of the two chute 13 are relatively arranged, facing the material channel of the second connecting frame 112, and the slider 14 is configured on the third baffle of the third connecting frame 121 corresponding to the two chute 13. Preferably, the outer edges of the two relatively arranged third baffles form the slider 14, and the chute 13 can support the outer edges of the two third baffles that form the slider 14, increase the support area, and make the connection between the fixed frame 12 and the connecting frame 11 more stable. The two sliders 14 are respectively inserted into the two chute 13, so that the fixed frame 12 can be connected to the connecting frame 11, and when the slider 14 is pulled out of the chute 13, the fixed frame 12 can be separated from the connecting frame 11.

[0037] Preferably, reinforcing plates connecting the two third baffles are provided at the front and rear ends of the two third baffles. The two third baffles and the two reinforcing plates enclose a rectangular frame, which increases the rigidity of the third connecting frame 121 and facilitates pushing the third connecting frame 121; at the same time, a closed material channel is formed, which can enhance the shielding effect when the material falls.

[0038] As a preferred implementation of this embodiment, the width of the chute 13 decreases gradually from the front end to the rear end, and the rear end width of the chute 13 is adapted to the thickness of the slider 14, so that the chute 13 forms a wedge shape, and the front end width of the chute 13 is greater than the thickness of the slider 14, so that the slider 14 is convenient to insert into the chute 13. The slider 14 is inserted from the front end of the chute 13. As the width of the chute 13 decreases, when the slider 14 moves to the rear end of the chute 13, the chute 13 and the slider 14 can be interference fit, and the slider 14 can be clamped by the chute 13 to achieve self-locking, preventing the slider 14 from moving outwards to exit the chute 13, causing the material channel of the third connection frame 121 to be misaligned with the material channel of the first connection frame 111. When the fixed frame 12 is pulled out, the slider 14 and the chute 13 can be unlocked with a little force, and the operation is convenient and quick.

[0039] It can be understood that the width of the slide groove 13 is the distance between two opposite groove walls of the slide groove 13 .

[0040] As a preferred implementation of this embodiment, the slide 13 is formed by enclosing a fixed plate 1121, a pad 1122 and a support plate 1123 which are arranged in sequence, and the pad 1122 is detachably arranged between the fixed plate 1121 and the support plate 1123. For example, the pad 1122 can be fixed between the fixed plate 1121 and the support plate 1123 by a bolt and nut assembly, and in the depth direction of the slide 13 formed by the three, the length of the pad 1122 is less than the length of the fixed plate 1121 and the support plate 1123, and the three can be enclosed to form the slide 13. The fixed plate 1121, the pad 1122 and the support plate 1123 enclose the slide 13, which has a simple structure, is easy to process and install, and the width of the slide 13 can be adjusted by adjusting the thickness of the pad 1122. Preferably, the thickness of the pad 1122 from the front end to the rear end gradually decreases, so that the width of the slide 13 from the front end to the rear end gradually decreases, so that the slider 14 and the slide 13 are self-locking. In order to facilitate processing, the pad 1122 can also be processed in sections and then installed between the fixing plate 1121 and the supporting plate 1123 .

[0041] In one embodiment, Figure 3As shown, the fixed component is configured as a slider 14, and the movable component is configured as a chute 13. Specifically, the slider 14 is configured on the second baffle plate opposite to the second connection frame 112, and preferably, the outer edges of the two oppositely configured second baffle plates form the slider 14, and the chute 13 is configured on the two oppositely configured third baffle plates of the third connection frame 121, and the openings of the two chute plates 13 are oppositely configured, facing the material channel of the third connection frame 121, and the chute 13 is inserted into the slider 14, and the slider 14 can support the chute 13. The two chute plates 13 are respectively inserted into the two sliders 14, so that the fixed frame 12 can be connected to the connection frame 11, and when the chute 13 is pulled out from the slider 14, the fixed frame 12 can be separated from the connection frame 11.

[0042] As a preferred implementation of this embodiment, the thickness of the slider 14 gradually increases from the front end to the rear end, and the thickness of the rear end of the slider 14 is adapted to the width of the chute 13, so that the slider 14 forms a wedge shape, and the front end width of the chute 13 is greater than the thickness of the slider 14, so that the chute 13 is conveniently inserted into the slider 14. The chute 13 is inserted from the front end of the slider 14. As the thickness of the slider 14 increases, when the chute 13 moves to the rear end of the slider 14, the chute 13 and the slider 14 can be interference-fitted, and the slider 14 can be clamped by the chute 13 to achieve self-locking, preventing the chute 13 from withdrawing outward along the slider 14, causing the material channel of the third connection frame 121 to be misaligned with the material channel of the first connection frame 111. When the fixed frame 12 is pulled out, the chute 13 and the slider 14 can be unlocked with a little force, and the operation is convenient and quick.

[0043] As a preferred embodiment of the present invention, a limit plate for blocking the movement of the movable part is provided at the front end of the movable part; and / or a limit plate for blocking the movement of the movable part is provided at the rear end of the fixed part. When the third connecting frame 121 is pushed into the second connecting frame 112, the limit plate can be used to block the movement of the movable part, and the pushing position of the third connecting frame 121 is limited so that the material channel of the third connecting frame 121 is aligned with the material channel of the first connecting frame 111, so as to facilitate the falling of the material and prevent the material from being blocked.

[0044] The limit plate can be set at the front end of the movable component. When the movable component is pushed along the fixed component, the limit plate can be pushed until it abuts against the front end surface of the fixed component. The limit plate can also be set at the rear end of the fixed component. When the movable component is pushed along the fixed component, the limit plate can be pushed until the rear end of the movable component abuts against the limit plate. Of course, the limit plate can also be set at the front end of the movable component and the rear end of the fixed component at the same time. When the limit plate is set at the rear end of the fixed component, it is more conducive to observing the alignment state of the movable component and the fixed component when the movable component is inserted into the fixed component, and the installation is more convenient and quick.

[0045] As a preferred embodiment of the utility model, the fixed component is set as a slope that is inclined downward from the front end to the rear end. At this time, when the movable component is pushed in along the fixed component, the movable component moves slightly downward, and can be self-locked under the action of gravity to prevent the movable component from moving upward, causing the material channel of the third connection frame 121 to be misaligned with the material channel of the first connection frame 111. When the fixed component is set as a chute 13, the width of the chute 13 from the front end to the rear end gradually decreases; or when the fixed component is set as a slider 14, the width of the slider 14 from the front end to the rear end gradually increases, setting the fixed component as a slope is more conducive to the downward movement of the movable component, so that the movable component and the fixed component are self-locked. Preferably, the angle between the slope and the horizontal plane is set to 2-10°; more preferably, the angle between the slope and the horizontal plane is set to 2-5°. By setting a suitable angle, for example, the angle between the slope and the horizontal plane can be set to 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc., this can prevent the angle from being too large, making the slope too steep and laborious when pulling out the fixed frame 12; it can also prevent the angle from being too small, making the slope too gentle and affecting the locking effect.

[0046] In order to facilitate pushing and pulling the fixed frame 12, a rigidly connected handle 15 can be provided at the front end of the fourth connection frame 122. The handle 15 is used to push and pull the fixed frame 12, which is convenient to apply force and comfortable to operate. In order not to affect the installation and removal of the barrier skin 300, it is better to stagger the installation positions of the handle 15 and the barrier skin 300. When the installation position of the handle 15 overlaps with the barrier skin 300, the handle 15 can be detachably provided on the fourth connection frame 122, the barrier skin 300 is first installed on the fourth connection frame 122, and then the handle 15 is pressed on the barrier skin 300 and installed on the fourth connection frame 122.

[0047] The utility model also provides a drop hopper 200, such as Figure 4 As shown, the fixing assembly 100 including the above-mentioned baffle 300 also includes a blanking port fixing frame 21 and the baffle 300 , the first connecting frame 111 is sleeved on the blanking port fixing frame 21 , and the baffle 300 is fixed to the fourth connecting frame 122 .

[0048] Specifically, a plurality of first connection holes 1111 that are compatible with the mounting holes 211 of the blanking port fixing frame 21 originally used to fix the baffle skin 300 can be set on the first connection frame 111, and a plurality of second connection holes 1221 that are compatible with the fixing holes 31 of the baffle skin 300 can be set along the circumferential direction on the fourth connection frame 122. When installing the connection frame 11, the first connection frame 111 is sleeved on the blanking port fixing frame 21, and the first connection holes 1111 are aligned with the mounting holes 211 of the blanking port fixing frame 21, and then they are fastened by the bolt and nut assembly. When installing the baffle skin 300, the fixing holes 31 of the baffle skin 300 are aligned with the second connection holes 1221, and then they are fastened by the bolt and nut assembly. In this way, there is no need to modify the blanking port fixing frame 21 and the baffle skin 300. It is only necessary to install the fixing assembly 100 of the baffle skin 300 to separate the baffle skin 300 from the blanking port fixing frame 21, and to achieve off-site cleaning of the baffle skin 300. It reduces the cleaning time and labor intensity of operators, improves work efficiency, and at the same time improves the safety of operations and improves product quality.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
