Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a material guiding device for tobacco processing. Background Technology

[0002] Tobacco processing is the process of turning raw materials such as tobacco leaves and stems into shredded tobacco that meets the requirements for cigarette making through a series of processes including slicing, drying, and screening. It is a key preliminary step in cigarette production. The reason for using a material guiding device in tobacco processing is that the transportation of materials (such as tobacco leaves and shredded tobacco) must strictly follow the process path. This device can guide, divert, or converge the materials to ensure uniform distribution and precise positioning during transportation, avoiding accumulation, deviation, or scattering. This ensures the stability of subsequent processes such as shredding and drying, improves the quality of tobacco processing, and increases production efficiency. It is an important auxiliary device in the tobacco processing production line for achieving orderly material transport and process integration.

[0003] The structure of a material guiding device for tobacco processing typically comprises multiple components working in tandem. It generally includes a carrying platform with a material conveying mechanism consisting of side baffles, a conveyor belt, a motor, and conveyor rollers for transporting materials. At both ends are a discharge box and a receiving platform to receive and place materials. Material gathering devices on both sides of the platform, such as those consisting of connecting blocks, guide blocks, inflation components, and reset components, limit the width of the material. A material flattening and grouping mechanism spanning the conveying mechanism includes a connecting cavity, connecting rod, handle, fixing block, height adjustment component, and sliding plate, enabling material flattening and grouping. Furthermore, special types, such as the material guiding device at the outlet of a tobacco drying machine, also consist of a guide box, a buckle plate, and a sealing plate, used to engage with the vibrating trough baffle and seal gaps. Although the structures of different devices vary, they are all designed around the goal of efficient and precise material guiding and conveying.

[0004] In existing technologies, the screen holes in some tobacco processing material guiding devices become clogged after prolonged use, which significantly reduces the material screening efficiency, affects the uniform dispersion of materials, and consequently leads to uneven parameters such as tobacco thickness and humidity in subsequent processing steps, severely reducing the quality of tobacco. Therefore, a tobacco processing material guiding device is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a material guiding device for tobacco processing, aiming to improve the problem that in existing technologies, the screen holes on the screen plate become clogged after long-term use, which greatly reduces the material screening efficiency, affects the uniform dispersion of materials, and leads to uneven parameters such as tobacco thickness and humidity in subsequent tobacco processing, seriously reducing the quality of tobacco.

[0006] The technical solution provided by this utility model is as follows:

[0007] This utility model provides a material guiding device for tobacco processing, including a support plate with a screen box on the upper left and a transmission mechanism on the upper right. The top of the screen box has a feed inlet and the lower side wall corresponding to the transmission mechanism has a discharge outlet. The inner top wall of the screen box is connected to a screen plate through a spring reset member. Below the screen plate is an inclined plate that connects to the discharge outlet and a first pushing member for driving the screen plate to vibrate up and down. The first pushing member includes an electric cylinder on the front and rear sides of the outer wall of the screen box and a first moving rod on the lower sides of the screen plate corresponding to the electric cylinder. The driving end of the electric cylinder is connected to a pushing rod with an inclined block on the opposite side of the driving end and extending into the screen box. The bottom end of the first moving rod is fixedly connected to a force-receiving block that slides with the inclined surface of the inclined block. The electric cylinder drives the inclined block to move back and forth, pushing the screen plate to compress the spring or release the spring, causing the screen plate to vibrate up and down.

[0008] Furthermore, the front and rear sides of the support plate on the transmission mechanism side are provided with transverse fixing plates, and the transverse fixing plates are fixedly connected with a second pushing member for bringing the tobacco closer to the center.

[0009] Furthermore, the second pushing component includes a cylinder and a second moving rod. The cylinder is installed on the outer side of the transverse fixed plate, and the output end of the cylinder is connected to a pushing block. A guide hole for the second moving rod to slide is passed through the transverse fixed plate. One end of the second moving rod is connected to a force-bearing block two located on the outer side of the transverse fixed plate, and the other end is connected to a pushing plate located on the inner side of the transverse fixed plate. The inclined surfaces of the pushing block and the force-bearing block two are in sliding cooperation. Under the action of the cylinder, the pushing block moves up and down, pushing the second moving rod to move stably along the guide hole to drive the pushing plate to move and make the tobacco move towards the center.

[0010] Furthermore, the screen box has mounting shells on its front and rear sides. An electric cylinder is fixedly connected to the outer side of the mounting shell. The driving end of the electric cylinder is provided with a push rod that passes through the mounting shell. The bottom of the mounting shell is provided with a guide seat in a concave shape corresponding to the bottom surface of the inclined block. The side wall of the screen box is provided with a sliding opening corresponding to the inclined block. The inner walls of the front and rear sides of the screen box are also fixedly provided with guide plates. The guide plates are provided with guide holes for the first moving rod to slide.

[0011] Furthermore, a fixed frame is connected to the top wall of the screen box, and a spring reset component is provided in the middle part of the front and rear sides of the fixed frame. The spring reset component includes a telescopic rod and a spring. The two ends of the telescopic rod are respectively connected to the lower part of the fixed frame and the lower part of the screen plate, and the spring is sleeved on the outer ring of the telescopic rod.

[0012] Furthermore, the transmission structure includes a conveyor belt and a drive roller. A groove is provided on the upper right side of the support plate, and drive rollers are respectively installed on the left and right sides of the groove. The two rotating rollers are connected to the conveyor belt. The drive rollers are connected to a drive motor. The bottom of the push plate is located above the conveyor belt.

[0013] Furthermore, the inclined block, force-bearing block one, pushing block and force-bearing block two are all cuboids with a notch in a right triangular prism.

[0014] Furthermore, the feed inlet is a conical feed port connected to the top of the screen box via a fixing ring.

[0015] Beneficial effects

[0016] This invention utilizes a structure where an inclined block driven by an electric cylinder slides into a force-bearing block at the bottom of the first moving rod, combined with a spring reset component. This structure efficiently and stably drives the screen plate to reciprocate up and down. The design is compact, with direct transmission, and the vibration force and frequency are easily controlled. It effectively disperses tobacco materials, prevents clumping and blockage, and ensures smooth passage of materials through the screen plate and discharge from the outlet. Simultaneously, the inclined plate design facilitates the material guiding and conveying mechanism, improving the smoothness and production efficiency of the entire material guiding process and ensuring the uniformity of tobacco shredding quality.

[0017] In this invention, the electric cylinder drives the push rod to move, which in turn moves the inclined block and the force-bearing block, thereby moving the first moving rod and causing the screen plate to vibrate. This achieves vibration cleaning of the screen plate and can also remove accumulated material on the screen plate in a timely manner, preventing screen hole blockage from affecting screening efficiency and ensuring the smoothness of the silk production process.

[0018] In this invention, the cylinder drives the push block to move, which in turn moves the second force-bearing block, which in turn moves the second moving rod, thereby driving the push plate to move. This enables the material on the conveyor belt to be gathered towards the center. In addition, it can concentrate the dispersed material on the conveyor belt towards the center, ensuring the stability of the material conveying path and thus avoiding spillage or accumulation caused by material deviation.

[0028] like Figure 1 and 2As shown, this utility model embodiment provides a material guiding device for tobacco shredding, including a screen box 2 located on the upper left and a support plate 1 located on the upper right with a transmission mechanism. The top of the screen box 2 has a feed inlet and the lower side wall corresponding to the transmission mechanism has a discharge outlet. The inner top wall of the screen box 2 is connected to a screen plate 10 through a spring reset member. Below the screen plate 10, there is an inclined plate that connects to the discharge outlet and a first pushing member for driving the screen plate 10 to vibrate up and down. The first pushing member includes an electric cylinder 4 located on the front and rear sides of the outer wall of the screen box 2 and a first moving rod 9 located on the lower sides of the screen plate 10 corresponding to the electric cylinder 4. The driving end of the electric cylinder 4 is connected to a pushing rod 5 with an inclined block 6 on one side opposite to the driving end and extending into the screen box 2. The bottom end of the first moving rod 9 is fixedly connected to a force block 8 that slides with the inclined surface of the inclined block 6.

[0029] This invention utilizes a structure where an inclined block driven by an electric cylinder slides into a force-bearing block at the bottom of the first moving rod, combined with a spring reset component. This structure efficiently and stably drives the screen plate to reciprocate up and down. The design is compact, with direct transmission, and the vibration force and frequency are easily controlled. It effectively disperses tobacco materials, prevents clumping and blockage, and ensures smooth passage of materials through the screen plate and discharge from the outlet. Simultaneously, the inclined plate design facilitates the material guiding and conveying mechanism, improving the smoothness and production efficiency of the entire material guiding process and ensuring the uniformity of tobacco shredding quality.

[0030] Example 2

[0031] like Figure 1 and Figure 2As shown in the figure, the present invention provides a material guiding device for tobacco processing, including a support plate 1, which is the foundation of the entire device. The bottom of the support plate 1 is also provided with support feet to support the device and make it stable. A screen box 2 is fixedly connected to the top left side of the support plate 1. The screen box 2 protects the internal mechanical components and makes them stable. A transmission mechanism is provided on the top right side of the support plate 1. The top of the screen box 2 is provided with a feed port and the side wall corresponding to the transmission mechanism is provided with a discharge port. The inner top wall of the screen box 2 is connected to a screen plate 10 through a spring reset member. The screen plate 10 screens the tobacco to remove internal impurities. Below the screen plate 10 is an inclined plate that connects to the discharge port and a first pushing member for driving the screen plate 10 to vibrate up and down. The first pushing member includes an electric cylinder 4 provided on the front and rear sides of the outer wall of the screen box 2 and a first moving rod 9 provided on the lower sides of the screen plate 10 corresponding to the electric cylinder 4.

The pushing rod 5 receives the electric cylinder 4 and moves, causing the inclined block 6 to move, thus stabilizing it. The bottom of the first moving rod 9 is fixedly connected to a force-receiving block 8. The force-receiving block 8 slides in contact with the inclined surface of the inclined block 6 and receives the pushing force of the inclined block 6, thus moving and stabilizing it, causing the first moving rod 9 to move and stabilize it. Driven by the electric cylinder 4, the inclined block 6 moves forward and lifts the force-receiving block through the inclined surface, driving the first moving rod 9 and the screen plate 10 to move upward and compress the spring reset component. When the inclined block 6 moves backward, the spring 13 releases its elastic force to push the screen plate 10 downward, thus realizing the continuous vibration of the screen plate 10. Figure 3 ).

[0032] In this embodiment, the front and rear sides of the support plate 1 on the transmission mechanism side are provided with transverse fixing plates 22, and the transverse fixing plates are fixedly connected with a second pushing member for bringing the tobacco closer to the center.

[0033] In this embodiment, the second pushing member includes a cylinder 14 and a second moving rod 16. The cylinder 14 is installed on the outer side of the transverse fixing plate 22.

The second moving rod 16 is connected to a force-bearing block 17 located on the outer side of the transverse fixing plate 22, and the other end is connected to a pushing plate 18 located on the inner side of the transverse fixing plate 22. The inclined surfaces of the pushing block 15 and the force-bearing block 17 slide together. Under the action of the cylinder 14, the pushing block 15 moves up and down to push the second moving rod 16 to move stably along the guide hole so as to drive the pushing plate 18 to move and make the tobacco move towards the center.

[0034] Specifically, refer to Figure 2 and Figure 4The second pushing member includes two transverse fixing plates 22.

A force-receiving block 17 is fixedly connected to one end of the second moving rod 16 located on the outer side of the transverse fixing plate 22. A pushing plate 18 is fixedly connected to one end of the second moving rod 16 located on the inner side of the transverse fixing plate 22. The force-receiving block 17 moves under the pushing force of the pushing block 15, so that the pushing plate 18 moves on the second moving rod 16.

[0035] In this embodiment, the screen box 2 has mounting shells 3 on the front and rear sides of its outer wall. The mounting shells 3 protect the internal assembly and make it stable. An electric cylinder 4 is fixedly connected to the outer side of the mounting shell 3. The driving end of the electric cylinder 4 is provided with a push rod 5 that passes through the mounting shell 3. The bottom of the mounting shell 3 is provided with a guide seat 19 in a concave shape corresponding to the bottom surface of the inclined block 6. The guide seat 19 allows the inclined block 6 to move and make it stable. The side wall of the screen box 2 has a sliding opening corresponding to the inclined block 6. The inner walls of the front and rear sides of the screen box 2 are also fixedly provided with guide plates 7. The guide plates 7 have guide holes for the first moving rod 9 to slide.

[0036] In this embodiment, a fixed frame 11 is connected to the inner top wall of the sieve box 2.

The top of the screen box 2 is fixedly connected to the fixing ring 20, and the top of the fixing ring 20 is fixedly connected to the conical feed port 21. The fixing ring 20 is a connecting component that connects the conical feed port 21 to the screen box 2.

[0041] Working principle: The electric cylinder 4 moves the push rod 5, which in turn moves the inclined block 6, which in turn moves the guide plate 7, which in turn moves the first moving rod 9, which in turn moves the top screen plate 10, causing the spring 13 and the telescopic rod 12 to press. When the inclined block 6 retracts, it causes the force-bearing block 8 to move downward. At this time, the spring 13 and the telescopic rod 12 release their force, thereby driving the screen plate 10 to move downward. This back-and-forth motion causes the screen plate 10 to vibrate up and down.

[0042] When the sieved tobacco is placed onto the conveyor belt by the inclined plate, and the tobacco falls onto both sides of the conveyor belt, the sensor inside the conveyor belt activates the cylinder 14. The drive end of the cylinder 14 moves the push block 15, which in turn moves the force block 17, which in turn moves the second moving rod 16, thereby moving the push plate 18. This causes the push plate 18 to bring the tobacco from both sides of the conveyor belt closer to the center.
