Description

Technical Field

[0001] The utility model relates to the technical field of tobacco auxiliary equipment, and more specifically, to a pushing device for a vertical feeding system. Background Art

[0002] Currently, tobacco cutting machines used in tobacco processing primarily cut tobacco leaves and stems into chips. The vertical feeding system in existing vertical feed cutting machines consists of four main components: a material distribution device, a material guide device, a material pusher, and a chain system. The pusher pushes the incoming material into the chain system for cutting.

[0003] However, when the pushing device is used to push the material, the material slides into the chain system, and the introduced material is loose, causing the material entering the pushing device to be loose. After the pushing device pushes the material, the loose material falls into the chain system, making it inconvenient to cut the material, thereby reducing the tobacco cutting effect.

[0004] Therefore, how to provide a pushing device for a vertical feeding system has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0025] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] Example 1

[0027] Reference Figure 1-3 The present invention provides a pushing device for a vertical feeding system, comprising a housing 1. A feed pipe 2 is connected to the upper end of the housing 1, and a guide rack 3 is connected to the lower end of the housing 1. The housing 1 and the guide rack 3 are integrally structured, effectively improving the structural strength of the housing 1 and the guide rack 3 and extending their service life. The width of the guide rack 3 gradually decreases from top to bottom, allowing material to accumulate at the bottom of the guide rack 3, thereby facilitating extrusion processing of the material. A discharge port 4 is provided at the bottom end of the guide rack 3.

[0028] A mounting plate 5 is fixedly connected to the box body 1, a servo motor 6 is fixedly connected to the mounting plate 5, a fixing sleeve 7 is fixedly connected to the output end of the servo motor 6, a connecting rod 8 is fixedly connected to the fixing sleeve 7, an arc rod 9 is fixedly connected to the upper end of the connecting rod 8, a through hole 10 is opened on the box body 1, one end of the arc rod 9 passes through the through hole 10, and a pressure plate 11 is fixedly connected to one end of the arc rod 9, and an anti-corrosion layer is sprayed on the pressure plate 11.

[0029] The servo motor 6 drives the fixed sleeve 7 to rotate, and then drives the connecting rod 8 to rotate. The rotation of the connecting rod 8 drives the arc rod 9 and the pressure plate 11 to move back and forth in the guide frame 3, so that the pressure plate 11 squeezes the material at the bottom of the guide frame 3.

[0030] It should be noted that, during use, the operator first needs to set the number of revolutions of the fixing sleeve 7 driven by the servo motor 6 , thereby controlling the moving distance of the pressing plate 11 .

[0031] The working process of the pushing device for the vertical feeding system of the utility model embodiment is as follows:

[0032] During operation, the material is introduced into the box body 1 through the feed pipe 2, and the material in the box body 1 falls into the guide rack 3. The servo motor 6 is powered on and started. After the servo motor 6 is started, it first drives the fixed sleeve 7 to rotate clockwise for a set number of turns, and then drives the fixed sleeve 7 to rotate counterclockwise for a set number of turns. The fixed sleeve 7 drives the connecting rod 8 to rotate, and the connecting rod 8 drives the arc rod 9 to rotate reciprocatingly. The arc rod 9 drives the pressing plate 11 to move back and forth in the vertical direction. When the pressing plate 11 moves downward, the material in the box body 1 falls into the guide rack 3. During the downward movement of the pressing plate 11, the material at the bottom of the guide rack 3 is squeezed. The material is compacted after extrusion, reducing the gap between the materials. The extruded material is released from the discharge port 4. After reducing the gap between the materials, the shredding effect of the material is improved.

[0033] Example 2

[0034] In Example 1, when the material at the bottom end of the material guide frame 3 is squeezed by the downward movement of the pressing plate 11 , the bottom end of the material guide frame 3 lacks support, thereby reducing the squeezing effect of the material.

[0035] Reference Figure 4 As another preferred embodiment of the present invention, the difference from Example 1 is that a buffer mechanism 13 is connected to both sides of the bottom end of the guide frame 3, the buffer mechanism 13 includes a clamping block 131, a movable hole is opened on the guide frame 3, and a slidable connecting clamping block 131 is on the movable hole. The bottom end of the outer wall of the guide frame 3 is fixedly connected to a support plate 133, and a spring 132 is fixedly connected to the support plate 133. One end of the spring 132 is fixedly connected to the clamping block 131. The clamping block 131 is located on one side of the guide frame 3 and is inclined toward the discharge port 4. A gap is provided on the opposite side of the two clamping blocks 131, and the material falls into the gap.

[0036] After the pressing plate 11 moves downward, it falls into the gap and squeezes the material in the gap. After the material is squeezed, it pushes the clamping block 131, and the clamping block 131 squeezes the spring 132. After the spring 132 is compressed, it generates elastic force. The elastic force generated by the spring 132 supports the clamping block 131, and the clamping block 131 supports the squeezed material. As the pressing plate 11 continues to move downward, the pressure on the clamping block 131 gradually increases, and the gap between the two clamping blocks 131 increases. The squeezed material passes through between the two clamping blocks 131 and is supported by the two clamping blocks 131, thereby improving the extrusion effect of the material.

[0037] It should be noted that the operator can control the degree of material compression by changing the spacing between the two clamping blocks 131. To increase the degree of material compression, the operator reduces the spacing between the two clamping blocks 131; to reduce the degree of material compression, the operator increases the spacing between the two clamping blocks 131, thereby adjusting the degree of material compaction as needed.

[0038] Example 3

[0039] As another preferred embodiment of the present invention, the difference from Example 1 is that the pushing device for the vertical feeding system also includes a baffle 12, the baffle 12 is arranged on the inner wall of the box body 1, and the baffle 12 is arranged above the through hole 10.

[0040] The baffle 12 has an arc-shaped structure and a certain length, so that the baffle 12 is covered above the arc rod 9. The baffle 12 blocks the material introduced into the box body 1 from the feed pipe 2, so that the material will not fall from the through hole 10 to the outside of the box body 1, thereby avoiding waste of material and effectively reducing the cost of use.

[0041] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
