Description

Technical Field

[0001] The utility model belongs to the field of packaging equipment, and particularly relates to a self-adjusting material conveying mechanism of an express bag packaging machine. Background Art

[0002] With the rapid development of the logistics and express delivery industry, the demand for consumables such as packaging bags for logistics packaging has also increased rapidly. In order to meet the demand for modern logistics packaging bags, there is an urgent need to provide a device that can quickly and automatically produce packaging bags for logistics.

[0003] Although some traditional express bag packaging machines achieve automated production, the control of material (15) conveyance during the production process is not ideal. Some materials (15) are conveyed too slowly, affecting production efficiency, and some material (15) conveyance rates are unstable, affecting product quality. Content of the Utility Model

[0004] To solve the problems and deficiencies existing in the prior art, the purpose of the present utility model is to provide a self-adjusting material conveying mechanism of an express bag packaging machine.

[0005] The self-adjusting material conveying mechanism of an express bag packaging machine includes a material cylinder winding roller (2), an adjusting transition roller, a material distributing roller, and a frame (1). The material cylinder winding roller (2) is arranged at the bottom of the back of the frame (1). A driving motor is arranged on one side of the material cylinder winding roller (2) to drive the material cylinder winding roller (2) to rotate. The material distributing roller and the adjusting transition roller are arranged in the frame (1). The material distributing roller is arranged at the upper end of the frame (1), and the adjusting transition roller is arranged below the material distributing roller. Guide rails (4) are arranged on both sides of the adjusting transition roller. Both ends of the adjusting transition roller are sleeved on the guide rails (4) and can move up and down along the guide rails (4). The material (15) is stretched starting from the material cylinder winding roller (2), passes through the material distributing roller, then reaches the adjusting transition roller, and is then transmitted through the material distributing roller again.

[0006] Further, a photoelectric sensor (12) is arranged near the bottom of the guide rail (4), and corresponding induction plates (13) are arranged on both sides of the adjusting transition roller.

[0007] Further, the number of material distributing rollers is 3, and the three are arranged horizontally at equal distances. The three are, from far to near relative to the frame (1), the first material distributing roller (8), the second material distributing roller (9), and the third material distributing roller (10).

[0008] Further, the number of adjusting transition rollers is 2, and the two are arranged horizontally. The two are, from far to near relative to the frame (1), the first adjusting transition roller (6) and the second adjusting transition roller (7).

[0009] Further, a bracket (11) is also arranged on the photoelectric sensor (12). A long groove is arranged on the bracket (11), and the photoelectric sensor (12) is installed in the long groove and can adjust its height in the long groove.

[0010] Furthermore, a conical head sleeve plug (3) is also sleeved on the barrel winding roller (2). Two conical head sleeve plugs (3) are oppositely arranged on both sides of the barrel winding roller (2). Bolts for fastening to the barrel winding roller (2) are provided on the surface of the conical head sleeve plug (3).

[0011] Furthermore, a buffer limit block (5) is provided at the bottom of the guide rail (4).

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. Since the driving speeds of the rear-end feeding roller and the front-end barrel winding roller (2) cannot be exactly the same, adjustment is required between the two. In this technical solution, the rising or falling of the adjustment transition roller reflects the difference in feeding between the front and rear ends. Therefore, during the continuous downward movement of the adjustment transition roller, it indicates that the driving speed of the front-end barrel winding roller (2) is too fast. At this time, the driving motor of the front-end barrel winding roller (2) needs to be paused. At this time, the adjustment transition roller gradually rises again as the material (15) is transmitted, and the front-end barrel winding roller (2) is started again. Thus, the function of automatically adjusting the conveyance of the material (15) is achieved.

[0014] 2. The material (15) is repeatedly wound and transmitted between the material distribution roller and the adjustment transition roller. Therefore, a relatively large amount of material (15) to be used can be stored between the two. When the front-end barrel winding roller (2) cannot keep up with the transmission speed of the material (15), sufficient buffer margin can be reserved, and the equipment will not stop or malfunction quickly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] The self-adjusting material conveying mechanism of the express bag packaging machine includes a barrel winding roller (2), an adjusting transition roller, a distributing roller, and a frame (1). The barrel winding roller (2) is arranged at the bottom of the back of the frame (1). One side of the barrel winding roller (2) is provided with a driving motor to drive the barrel winding roller (2) to rotate. The distributing roller and the adjusting transition roller are arranged in the frame (1). The distributing roller is arranged at the upper end of the frame (1), and the adjusting transition roller is arranged at the lower end of the distributing roller. Guide rails (4) are arranged on both sides of the adjusting transition roller. Both ends of the adjusting transition roller are sleeved on the guide rails (4) and can move up and down along the guide rails (4). The material (15) is stretched starting from the barrel winding roller (2), passes through the distributing roller, then reaches the adjusting transition roller, and then is transmitted through the distributing roller. A photoelectric sensor (12) is arranged near the bottom of the guide rail (4), and corresponding induction plates (13) are arranged on both sides of the adjusting transition roller. The number of distributing rollers is 3, and the three are arranged horizontally at equal distances. The three are, from far to near relative to the frame (1), the first distributing roller (8), the second distributing roller (9), and the third distributing roller (10). The number of adjusting transition rollers is 2, and the two are arranged horizontally. The two are, from far to near relative to the frame (1), the first adjusting transition roller (6) and the second adjusting transition roller (7). A bracket (11) is also arranged on the photoelectric sensor (12). A long groove is arranged on the bracket (11), and the photoelectric sensor (12) is installed in the long groove and can adjust its height in the long groove. A conical head sleeve plug (3) is also sleeved on the barrel winding roller (2). Two conical head sleeve plugs (3) are arranged oppositely on both sides of the barrel winding roller (2). Bolts for fastening to the barrel winding roller (2) are arranged on the surface of the conical head sleeve plug (3). A buffer limit block (5) is arranged at the bottom of the guide rail (4).

[0021] The actual usage method is as follows:

[0022] Assemble the barrel (14) on the barrel winding roller (2), and position both ends through the conical head sleeve plug (3). First, wind the material (15). The material (15) at the barrel (14) first bypasses the first distributing roller (8), then is pulled down, bypasses the first adjusting transition roller (6), comes out from the first adjusting transition roller (6) and bypasses the second distributing roller (9), comes out from the second distributing roller (9) and bypasses the second adjusting transition roller (7), comes out from the second adjusting transition roller (7) and bypasses the third distributing roller (10), and then enters the equipment.

[0023] When the material barrel winding roller (2) runs continuously or at a relatively high speed, the surplus of the material (15) between the material distributing roller and the adjusting transition roller increases, causing the adjusting transition roller to continuously move downward. When moving downward, it drives the induction plate (13) to move downward. When the induction plate (13) touches the photoelectric sensor (12), through the control system, the material barrel winding roller (2) stops or slows down its operation. After running in this state for a period of time, the surplus of the material (15) between the material distributing roller and the adjusting transition roller decreases, and the adjusting transition roller continuously moves upward. Eventually, the induction plate (13) leaves the sensing area of the photoelectric sensor (12).

[0024] Repeat the above process to achieve the automatic adjustment and conveying of the material (15).

[0025] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
