Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a pressure bar feeder. Background Technology

[0002] During cigarette manufacturing, processes such as tobacco processing and cigarette rolling generate a large amount of smoke and dust. Dust collectors are typically used to collect this smoke and dust before transporting it to a designated area. However, because the smoke and dust are loose, they can easily disperse during loading, unloading, and transportation, causing secondary pollution to the environment.

[0003] In the existing technology, the smoke and dust collected by the dust collector are compressed into solid bars by a bar press and then transported. This can greatly reduce the amount of smoke and dust flying around and reduce environmental pollution. In addition, the smoke and dust compressed into bars are smaller in volume, saving space and reducing the number of transportation trips, thereby reducing transportation costs.

[0004] The smoke and dust in the dust collector are usually transported to the storage hopper of the briquetting machine via a screw feeder. The screw feeder consists of a feeding cylinder and a feeding screw, with the screw located inside the feeding cylinder. A motor drives the screw to rotate, continuously feeding the smoke and dust entering the feeding cylinder into the storage hopper. However, the smoke and dust easily clog the feeding cylinder, preventing the feeding screw from rotating and damaging the motor. Furthermore, the feeding cylinder is difficult to disassemble and assemble, resulting in prolonged cleaning time and reduced production efficiency. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0030] like Figure 1 As shown, this embodiment provides a pressure bar feeder, including a screw feeder 1, a detection element 2, a control component 3, and a valve 4. The screw feeder 1 includes a feeding cylinder 11 and a feeding screw 12. The feeding screw 12 is disposed inside the feeding cylinder 11 and can convey materials horizontally. A discharge port is provided at the bottom of the feeding cylinder 11. The detection element 2 is installed at the top of the feeding cylinder 11, and the control component 3 is communicatively connected to the detection element 2. The valve 4 is disposed at the discharge port and is communicatively connected to the control component 3. The valve 4 has an open state and a closed state. When the valve 4 is in the open state, the interior of the feeding cylinder 11 communicates with the outside through the discharge port. When the valve 4 is in the closed state, the valve 4 blocks the discharge port. Under normal operating conditions, valve 4 is closed, allowing material to be conveyed horizontally. When material accumulates in the feeding cylinder 11, the detection element 2 detects it and transmits the signal to the control component 3. The control component 3 then opens valve 4, allowing the accumulated material to fall from the outlet. When the detection element 2 fails to detect material, the control component 3 closes valve 4, allowing the feeding screw 12 to continue operating. Through the combined action of the detection element 2, control component 3, and valve 4, material clogged in the feeding cylinder 11 can be automatically cleared, preventing damage to the motor and improving production efficiency.

[0031] Specifically, the feeding cylinder 11 has a cylindrical structure, and its axis extends horizontally. The detection element 2 is a capacitive proximity switch, with its measuring head facing the bottom of the feeding cylinder 11. When material approaches the measuring head of the detection element 2, it transmits a signal to the control component 3. After the detection element 2 transmits a signal to the control component 3 for a certain period, the control component 3 controls the valve 4 to open, preventing false detections by the detection element 2. In other embodiments, the detection element 2 can also be a photoelectric sensor. The valve 4 can also be manually opened or closed, increasing the operational options for the valve 4. The valve 4 is sealed to the side wall of the discharge port. The specific structure of the valve 4 is based on existing technology and will not be described in detail here.

[0032] Optionally, the control component 3 includes a power supply and a controller. The detection element 2 and the valve 4 are wired to the controller, which is electrically connected to the power supply. The controller can receive and send signals to control the opening and closing of the valve 4, and the power supply can provide current to the controller. The specific structure of the controller is described in accordance with the prior art and will not be elaborated here.

[0033] Optionally, the press bar feeder also includes a collection device 5, which is located below the feeding cylinder 11 and is connected to the discharge port. The collection device 5 can collect the material falling from the discharge port to prevent the falling material from polluting the environment.

[0034] Optionally, the collection device 5 includes a waste bin 51, which is provided with an inlet and an outlet, and the material falling from the inlet falls directly into the waste bin 51.

[0035] Furthermore, the collecting device 5 also includes a conveying pipe 52, the first end of which is connected to the discharge port and the second end of which is connected to the inlet port. The conveying pipe 52 facilitates the connection between the inlet port and the discharge port. Specifically, the conveying pipe 52 has an L-shaped structure, and the first end of the conveying pipe 52 is fixed to the outer wall of the feeding cylinder 11 and connected to the discharge port.

[0036] Furthermore, the waste bin 51 and the conveying pipe 52 are detachably connected, facilitating the installation and removal of the waste bin 51 and the conveying pipe 52, thereby making it convenient to clean the material inside the waste bin 51. Specifically, the outer wall of the second end of the conveying pipe 52 is threadedly connected to the inner wall of the feed inlet.

[0037] Optionally, the collection device 5 also includes a negative pressure generator 53, which is installed on the waste bin 51. The negative pressure generator 53 can create a negative pressure inside the waste bin 51. Through the adsorption of the negative pressure, the material that falls into the conveying pipe 52 is sucked into the waste bin 51, thus preventing the material from clogging the conveying pipe 52.

[0038] Furthermore, a mounting hole is provided on the side of the waste bin 51 opposite to the feed inlet. The negative pressure generator 53 is installed on the outer wall of the waste bin 51 and communicates with the mounting hole, thereby fixing the negative pressure generator 53. The negative pressure generator 53 is positioned opposite to the feed inlet, which improves the adsorption effect of the negative pressure generator 53 on the material. The negative pressure generator 53 can be fixed to the outer wall of the waste bin 51 by means of screw connection or adhesive bonding, etc., which is not limited in this embodiment.

[0039] Optionally, the collecting device 5 also includes a filter element 54, which is installed in the mounting hole and located on the side of the negative pressure generator 53 facing the feed inlet. The filter element 54 can block materials, preventing them from contacting the negative pressure generator 53 and thus clogging it, thereby improving the service life of the negative pressure generator 53. Specifically, the filter element 54 is a filter screen, and its size is adapted to the size of the mounting hole. The filter element 54 is snapped and fixed to the inner wall of the mounting hole.

[0040] Optionally, the pressure bar feeder also includes an alarm device 6, which is communicatively connected to the control component 3. When the detection element 2 sends a signal to the control component 3, and the control component 3 controls the valve 4 to open, the control component 3 also controls the alarm device 6 to sound an alarm, so that the operator can be notified of material blockage in the feeding cylinder 11 and check the blockage situation. Specifically, the alarm device 6 is an audible and visual alarm.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
