Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco auxiliary production equipment, specifically relating to a tobacco turnover box cleaning device. Background Technology

[0002] In the tobacco production process, tobacco leaves, shredded tobacco, and other tobacco products are placed in turnover boxes for storage or transportation. During the vacuum rehumidification process in the tobacco processing workshop, the turnover boxes and the tobacco placed inside them enter the vacuum rehumidification equipment for vacuuming, heating, and humidification. After humidification, the tobacco easily adheres to the inner wall of the turnover box. When the box is turned over and the tobacco is poured out, some tobacco remains stuck to the inner wall and cannot be completely removed. To prevent the tobacco adhering to the inner wall of the turnover box from mixing with the next batch of tobacco, a blower cleaning device is typically used to clean the inner wall of the turnover box.

[0003] However, damp tobacco adheres quite firmly, and tobacco in areas that are not properly cleaned by the blowing mechanism is difficult to remove. Therefore, it is usually necessary to operate the blowing mechanism to directly blow the entire inner wall of the turnover box in order to clean it thoroughly, resulting in low cleaning efficiency.

[0055] Please refer to the following: Figures 1 to 4 The cleaning device for tobacco turnover boxes provided by this utility model will now be described. The cleaning device for tobacco turnover boxes includes a frame 10, a holding rack, a first pressing component, a vibration component 50, and a blowing component. The frame 10 is fixedly installed. The holding rack is connected to the frame 10 and has a slot on it. The turnover box 90 is suitable for being placed upside down into the slot. The first pressing component is connected to the frame 10, and its power output end is suitable for applying low pressure to the turnover box 90 to press it. The power output end of the vibration component 50 is connected to the holding rack to drive the holding rack to vibrate. The blowing component has a nozzle 60 and is connected to the frame 10. The nozzle 60 has a first blowing port and a second blowing port on its top. The opening of the first blowing port faces upward, and the second blowing port is arranged around the first blowing port and tilted outward. The nozzle 60 is suitable for being placed inside the turnover box 90.

[0056] It should be noted that the vibration component 50 is a vibrator, which is fixedly connected to the holding rack.

[0057] In addition, the vibration component 50 can also be a pneumatic rapping device or a device that can reciprocate at a certain frequency to strike the container rack, causing the container rack to vibrate.

[0058] The beneficial effects of the tobacco turnover box cleaning device provided by this utility model are as follows: Compared with the prior art, the tobacco turnover box cleaning device provided by this utility model has the turnover box 90 upside down on the holding rack, and the turnover box 90 is pressed tightly on the holding rack by the first pressing component, so that the vibration component 50 vibrates together with the holding rack and the turnover box 90 on it. Through vibration, the tobacco adhering to the inner wall of the turnover box 90 can easily form gaps with the inner wall, thereby making it easier for the airflow blown by the blowing component to enter between the tobacco and the inner wall, blowing off the adhering tobacco, effectively improving the cleaning efficiency; and the top of the nozzle 60 of the blowing component is provided with a first blowing port with an upward opening, which is used to blow the bottom of the turnover box 90, and a second blowing port that surrounds the first blowing port and is inclined outward, which is used to guide the airflow to the four sides of the turnover box 90 to blow and clean the side walls. Therefore, during the blowing operation, it is necessary to operate and move the nozzle 60 to form airflow on the bottom and side wall surfaces of the turnover box 90, further improving the cleaning efficiency.

[0059] like Figure 2 and Figure 3 As shown, in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, the nozzle 60 includes a housing 61, an air guide sleeve 62, and several connecting plates 63. The housing 61 is trumpet-shaped with the small end facing downwards. The air guide sleeve 62 is coaxially disposed inside the housing 61, is trumpet-shaped, and has the small end facing downwards. Several connecting plates 63 are disposed between the housing 61 and the air guide sleeve 62, and are connected to the housing 61 and the air guide sleeve 62. The top of the air guide sleeve 62 is a first spray nozzle, and the space between the air guide sleeve 62 and the housing 61 is a second spray nozzle.

[0060] During operation, part of the airflow is ejected through the air guide sleeve 62 and sprays the bottom of the turnover box 90; part of the airflow is ejected through the gap between the outer shell 61 and the air guide sleeve 62, i.e. the second spray nozzle, and flows to the surroundings under the guidance of the air guide sleeve 62 and the outer shell 61, spraying the inner wall of the turnover box 90.

[0061] The number of connecting plates 63 can be one, two or more.

[0062] Furthermore, at least three connecting plates 63 are provided, and the connecting plates 63 are spirally arranged so that the airflow passing between the outer shell 61 and the air guide sleeve 62 rotates in a spiral, making the blowing more uniform and the tobacco easier to fall off.

[0063] like Figure 1 and Figure 2As shown, in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, the blowing assembly further includes an air pipe 71 and a lifting assembly 72. The air pipe 71 is a rigid pipe, with its upper end connected and connected to the lower end of the outer shell 61, and its lower end passing downward through the holding rack. The air pipe 71 is connected to an air source. The lifting assembly 72 is connected to the frame 10, and its power output end is connected to the air pipe 71 to drive the air pipe 71 and the nozzle 60 to move up and down.

[0064] Specifically, the lower part of the vent pipe 71 is equipped with an air passage connector, which connects to an air source through a pipeline; the air source is an air pump, an air tank, and a workshop air passage. The lifting component 72 is a cylinder, but it can also be replaced by an electric actuator, a hydraulic cylinder, etc., used to drive the nozzle 60 to move down after the spraying is completed, so as to remove the turnover box 90.

[0065] The frame 10 is equipped with a mounting plate, and the mounting plate is equipped with a sliding sleeve. The lifting component 72 is connected to the mounting plate, and the air pipe 71 slides with the sliding sleeve, making the movement of the air pipe 71 more stable and less prone to tilting.

[0066] like Figure 1 and Figure 2 As shown in the embodiment of the tobacco turnover box cleaning device provided in this utility model, the air pipe 71 is spaced 0.5-2mm apart from the holding rack along the circumference, so that the air pipe 71 and the holding rack are separated to avoid the holding rack from colliding with the air pipe or causing the air pipe to vibrate together when it vibrates, thus ensuring the service life of the blowing assembly.

[0067] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, the holding rack includes a holding rack, two baffles 21 and a limiting plate 23, and a receiving plate 24 for receiving tobacco; the two baffles 21 are disposed on the upper side of the receiving plate 24 and are fixedly connected to the receiving plate 24, the two baffles 21 are parallel and spaced apart, and a step pad 22 is provided at the bottom of the opposite side, the upper side of the step pad 22 is used to abut against the turnover box 90; the limiting plate 23 is disposed at one end of the baffle 21 and between the two baffles 21, and is connected to the receiving plate 24 or the baffle 21; wherein, a slot is formed between the baffle 21, the step pad 22 and the limiting plate 23, and the slot is open on the side and top facing away from the limiting plate 23 to facilitate the placement of the turnover box 90 inside.

[0068] The top edges of the two step pads 22 on opposite sides do not protrude from the turnover box 90 to avoid tobacco accumulation.

[0069] Preferably, the sidewalls of the two step pads 22 on opposite sides are flush with or recessed inside the sidewalls of the turnover box 90, so as to effectively prevent tobacco from accumulating on the step pads 22.

[0070] There are two limiting plates 23, which are respectively set on the opposite side of the two baffles 21 and fixedly connected to the baffles 21, so as to save materials while effectively limiting the position of the turnover box 90.

[0071] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, the first pressing component includes a first cylinder 31 and a first push plate 32. The first cylinder 31 is located on the upper side of the holding rack and is connected to the frame 10; the first push plate 32 is connected to the piston rod of the first cylinder 31 and is used to abut against the top of the turnover box 90.

[0072] It should be noted that the first cylinder 31 can also be replaced by a hydraulic cylinder, electric actuator, or other device that can output displacement and maintain a certain pressure.

[0073] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, two second pressing components are also included. The two second pressing components are respectively disposed on the outside of the two baffles 21 and connected to the frame 10. The power output end of the second pressing component abuts against the baffle 21 to push the baffle 21 so that the baffle 21 abuts against the turnover box 90.

[0074] Preferably, the side of the turnover box 90 is spaced 0.5-2mm from the baffle 21 so that the turnover box 90 can be placed between the two baffles 21. The baffle 21 is a plate with a certain degree of toughness so that it can make close contact with the side of the turnover box 90 under the push of the second clamping component, so that the generated vibration can be transmitted to the side of the turnover box 90, thereby effectively transmitting the vibration to the entire turnover box 90.

[0075] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, the second pressing component includes a second cylinder 41 and a second push plate 42. The second cylinder 41 is located on the side of the baffle 21 and connected to the frame 10; the second push plate 42 is connected to the piston rod of the second cylinder 41 and is used to abut against the baffle 21.

[0076] It should be noted that the second cylinder 41 can also be replaced by a hydraulic cylinder, electric actuator, or other device that can output displacement and maintain a certain pressure.

[0077] like Figure 1 and Figure 2As shown in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, it further includes a first spring 33, a second spring 43 and a plurality of third springs 11. The first spring 33 is disposed between the piston rod of the first cylinder 31 and the first push plate 32, and its two ends are connected to the piston rod of the first cylinder 31 and the first push plate 32. The second spring 43 is disposed between the piston rod of the second cylinder 41 and the second push plate 42, and its two ends are connected to the piston rod of the second cylinder 41 and the second push plate 42. The plurality of third springs 11 are disposed between the receiving plate 24 and the frame 10, and their two ends are connected to the receiving plate 24 and the frame 10.

[0078] It should be noted that the vibration transmitted to the first cylinder 31 and the second cylinder 41 is weakened by the first spring 33 and the second spring 43, thereby reducing the impact of vibration on the service life of the first cylinder 31 and the second cylinder 41. The third spring 11 is provided between the frame 10 and the receiving plate 24, which can effectively weaken the vibration transmitted to the frame 10 and reduce the impact of vibration on the outside.

[0079] Preferably, four third springs 11 are provided, which are evenly distributed between the mounting plate and the receiving plate 24 of the frame 10 to provide more stable support for the receiving plate 24 and to effectively control the length of the third springs 11 to avoid excessive absorption of vibration energy and affect the cleaning effect.

[0080] like Figure 1 and Figure 2 Figure 1 Figure 2 As shown, in a specific embodiment of the tobacco turnover box cleaning device provided in this utility model, a storage box 80 is also included. The receiving plate 24 is inclined and the storage box 80 is located on one side of the frame 10 to receive tobacco that slides off the receiving plate 24.

[0081] It should be noted that by tilting the receiving plate 24, the fallen tobacco can automatically slide off the receiving plate 24 into the storage box 80 under the vibration and residual airflow, thus automatically completing the cleaning and collection of the receiving plate 24 without the need for additional cleaning and collection of the tobacco on the receiving plate 24, thereby further improving work efficiency.

[0082] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
