Description

Technical Field

[0001] This utility model belongs to the field of toothpick production technology, and in particular relates to a toothpick packaging machine. Background Technology

[0002] Toothpicks are small tools used to clean between teeth and remove food debris, typically made of materials such as wood, bamboo, plastic, or metal. As a daily necessity that comes into direct contact with the oral cavity, the hygiene, safety, and portability of toothpicks are of paramount importance. Therefore, in modern manufacturing, toothpicks usually require packaging.

[0003] Traditional toothpick packaging machines typically use two pairs of heated sealing rollers: one pair for heating the horizontal seal and the other for heating the vertical seal and cutting. This step-by-step operation makes the horizontal and vertical sealing processes relatively independent, making it difficult to ensure the uniformity and consistency of heating at the seal. Incomplete seals are prone to occur at the junction of the horizontal and vertical seals, causing the toothpicks to easily become damp and contaminated during storage and transportation, affecting product quality and shelf life.

[0004] Therefore, a toothpick packaging machine is particularly needed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional toothpick packaging machines that use a step-by-step heating and sealing method, which can easily lead to incomplete sealing and affect the sealing performance and product quality, this utility model provides a toothpick packaging machine.

[0006] This utility model is achieved through the following technical means: A toothpick packaging machine includes a base, a connecting frame, a support column, a placement roller, a guide wheel, a drive roller, a shaping roller, a drive mechanism, a heating box, a heat sealing roller, a heat pressing block, a cutting roller, a limiting component, and a shaping component. The connecting frame is installed on one side of the upper part of the base, the support column is fixed to the upper part of the connecting frame, the placement roller is rotatably mounted on the cylindrical surface of the support column, the guide wheel is rotatably mounted on the lower part of the connecting frame, the drive roller is also mounted on the lower part of the connecting frame and located to the left of the guide wheel, and two shaping rollers are arranged side by side and rotatably mounted on the other side of the upper part of the base, with one end of each shaping roller... Extending into the interior of the base, the heating box is installed on the upper side of the base. Two heat-sealing rollers are also arranged side by side and rotated on the upper side of the base, located to the left of the two shaping rollers. One end of each heat-sealing roller extends into the interior of the base, and the other end is connected to the heating box. Multiple hot-pressing blocks are evenly distributed along the center of each heat-sealing roller. Two cutting rollers are also arranged side by side and rotated on the upper side of the base, located to the left of the two heat-sealing rollers. One end of each cutting roller extends into the interior of the base. The limiting component is located on the upper part of the connecting frame, and the shaping component is located on the upper side of the base.

[0007] To further explain, the drive mechanism includes a support frame, servo motors, spur gear sets, and transmission components. The support frame is installed on one side of the inner top of the base, and two servo motors are mounted side by side on it. A first spur gear set is set between one end of the two shaping rollers, and a second spur gear set is set between one end of the two heat-sealing rollers. The output shaft of one servo motor is fixedly connected to one end of one of the shaping rollers via a coupling, and the output shaft of the other servo motor is fixedly connected to one end of one of the heat-sealing rollers via a coupling. A transmission component is set between one end of the laterally aligned heat-sealing roller and the cutting roller, and there are a total of two transmission components.

[0008] To further explain, the limiting assembly includes a fixed plate, a guide rod, a sliding frame, a pressure roller, and a return spring. The fixed plate is installed on the upper side of the connecting frame, the sliding frame is slidably mounted on the fixed plate, the pressure roller is rotatably mounted on one side of the sliding frame, a guide rod is fixedly connected to the upper side of the fixed plate, the guide rod passes through the sliding frame and is slidably connected to it, and a return spring is sleeved on the rear of the sliding frame, with both ends of the return spring fixedly connected to the sliding frame and the fixed plate, respectively.

[0009] To further explain, the shaping component includes a support plate, a U-shaped plate, telescopic rods, a return spring, a pressure rod, a guide rod, and an adjusting rod. Two support plates are fixedly attached to the upper side of the base, one in front of the other. Each support plate has two telescopic rods arranged side by side at its top. The fixed end of each telescopic rod is fixedly connected to the support plate. The U-shaped plate is fixed between the movable ends of the multiple telescopic rods. A return spring is sleeved on the outside of each telescopic rod. The two ends of each return spring are fixedly connected to the U-shaped plate and the corresponding support plate, respectively. The guide rod is fixedly attached to one side of the top of the U-shaped plate. The adjusting rod is rotatably located on the other side of the top of the U-shaped plate. The pressure rod is threaded on the outside of the adjusting rod and forms a sliding fit with the guide rod. The pressure rod extends into the U-shaped groove of the U-shaped plate.

[0010] To further explain, it also includes a guide frame, which is also installed on the upper side of the base and located to the left of the connecting frame, with the U-shaped plate located to the left of the guide frame.

[0011] To further explain, a wheel is provided at the end of the adjusting rod away from the U-shaped plate.

[0012] Beneficial effects: 1. By integrating horizontal and vertical sealing functions into a pair of heat-sealing rollers, the packaging material is heated and sealed simultaneously. Compared with the traditional step-by-step sealing method, this design effectively avoids poor sealing caused by uneven heating and misalignment of the seal, significantly improves the uniformity and sealing performance of the seal, prevents toothpicks from getting damp or contaminated, and improves product stability and shelf life.

[0013] 2. By setting a limiting component, the pressure roller can always apply a constant tension to the packaging material under the action of the return spring, ensuring that it remains flat and stable during the conveying process. This effectively prevents packaging quality problems such as deviation, wrinkles or poor sealing caused by excessive stretching or loosening of the material, thereby improving the overall packaging accuracy and operational stability.

The connecting frame 2 is bolted to the upper right side of the base 1. The support column 3 is fixedly connected to the upper part of the connecting frame 2. The placement roller 4 is rotatably mounted on the cylindrical surface of the support column 3. The guide wheel 5 is rotatably mounted at the lower right side of the connecting frame 2. The drive roller 6 is also located at the lower right side of the connecting frame 2, to the left of the guide wheel 5. The guide frame 7 is also bolted to the upper right side of the base 1, to the left of the connecting frame 2. Two shaping rollers 8 are arranged side-by-side and rotatably mounted on the upper left side of the base 1, with the lower end of each shaping roller 8 extending into the interior of the base 1. The heating chamber... 12 bolts are connected to the upper left side of the base 1. Two heat sealing rollers 13 are also arranged side by side and rotated on the upper left side of the base 1, and are located to the left of the two shaping rollers 8. The lower end of each heat sealing roller 13 extends into the interior of the base 1, and the upper end is connected to the heating box 12 to receive heating energy and maintain the surface of the heat sealing roller 13 at a set temperature. The surface of each heat sealing roller 13 is provided with multiple heat pressing blocks 14 evenly distributed along its center, which are used to heat and seal the packaging material during the sealing process to achieve synchronous heat sealing in the horizontal and vertical directions. Two cutting rollers 15 are also arranged side by side and rotated on the upper left side of the base 1, and are located to the left of the two heat sealing rollers 13. The lower end of each cutting roller 15 extends into the interior of the base 1. The limiting component is located on the upper part of the connecting frame 2, and the shaping component is located on the upper right side of the base 1.

[0023] like Figure 5 and Figure 6 As shown, the drive mechanism includes a support frame 9, a servo motor 10, a spur gear set 11, and a transmission assembly 16. The support frame 9 is bolted to the inner top left side of the base 1, and two servo motors 10 arranged side by side are bolted to it. A first spur gear set 11 is arranged between the lower ends of the two shaping rollers 8, and a second spur gear set 11 is arranged between the lower ends of the two heat sealing rollers 13. The output shaft of the right servo motor 10 is fixedly connected to the lower end of the front shaping roller 8 through a coupling, and the output shaft of the left servo motor 10 is fixedly connected to the lower end of the front heat sealing roller 13 through a coupling. A transmission assembly 16 is arranged between the lower ends of the horizontally aligned heat sealing roller 13 and the cutting roller 15, and there are two transmission assemblies 16 in total.

[0024] like Figure 3As shown, the limiting assembly includes a fixed plate 17, a guide rod 18, a sliding frame 19, a pressure roller 20, and a return spring 21. The fixed plate 17 is bolted to the upper rear side of the connecting frame 2. The sliding frame 19 is slidably mounted on the fixed plate 17. The pressure roller 20 is rotatably mounted on the right side of the sliding frame 19. The guide rod 18 is fixedly connected to the upper left side of the fixed plate 17. The guide rod 18 passes through the sliding frame 19 and is slidably connected to it. A return spring 21 is sleeved on the rear of the sliding frame 19. The left and right ends of the return spring 21 are fixedly connected to the sliding frame 19 and the fixed plate 17, respectively, to provide a reset force for the sliding frame 19.

[0025] like Figure 7 As shown, the shaping assembly includes a support plate 22, a U-shaped plate 23, telescopic rods 24, a return spring 25, a pressure rod 26, a guide rod 27, and an adjusting rod 28. Two support plates 22 are fixedly connected to the upper right side of the base 1, arranged front to back. Each support plate 22 has two telescopic rods 24 arranged side-by-side at its top. The fixed end of each telescopic rod 24 is fixedly connected to the support plate 22. The U-shaped plate 23 is fixedly connected between the movable ends of the four telescopic rods 24 and is located to the left of the guide frame 7. Each telescopic rod 24 is fitted with a return spring 25. The upper and lower ends of each return spring 25 are fixedly connected to the U-shaped plate 23 and the corresponding support plate 22, respectively. The guide rod 27 is fixedly connected to the front of the top of the U-shaped plate 23. The adjusting rod 28 is rotatably set on the rear of the top of the U-shaped plate 23. A wheel is provided at the upper end of the rod away from the U-shaped plate 23. The pressure rod 26 is threaded on the outside of the adjusting rod 28 and forms a sliding fit with the guide rod 27. The pressure rod 26 extends into the U-shaped groove of the U-shaped plate 23.

[0026] In the initial state, the return spring 21 is under tension, and the pressure roller 20 is in the position closest to the placement roller 4. When toothpick sealing operation is required, the operator first installs the toothpick feeding device on the upper left side of the base 1 and makes its discharge port face the sealing area between the shaping roller 8 and the heat sealing roller 13. Then, pull the sliding frame 19 to the leftmost end of the guide rod 18 to move the pressure roller 20 away from the placement roller 4, making it easier to place the packaging material roll. After the packaging material roll is placed on the placement roller 4, release the sliding frame 19. Under the reset action of the return spring 21, the sliding frame 19 drives the pressure roller 20 to move to the right to press the outer layer of the packaging material roll. Next, the packaging material is pulled out and passed around the guide wheel 5 and introduced into the drive roller 6. Then, the adjusting rod 28 is rotated clockwise to drive the pressure rod 26 to move upward, so that it is disengaged from the U-shaped groove of the U-shaped plate 23. The packaging material is then passed between the U-shaped plate 23 and the pressure rod 26. Then, the adjusting rod 28 is rotated counterclockwise to move the pressure rod 26 downward and insert it into the U-shaped groove of the U-shaped plate 23. It works with the U-shaped plate 23 to limit the packaging material and form a stable U-shaped channel, providing a stable foundation for the subsequent shaping of the packaging material. The packaging material is then guided through the front and rear shaping rollers 8, the heat sealing roller 13, and the cutting roller 15 to complete the laying of the entire packaging path. Once everything is ready, start the toothpick feeding device, heating box 12, drive wheel 6, and two servo motors 10. Drive wheel 6 moves to the left to feed packaging material. The right servo motor 10 drives the front shaping roller 8 to rotate through the coupling. The first spur gear set 11 drives the rear shaping roller 8 to rotate synchronously. The two shaping rollers 8 work together to achieve the initial shaping of the packaging material, so that the packaging material gradually forms a shape that meets the requirements of toothpick packaging. At the same time, the left servo motor 10 drives the front heat sealing roller 13 to rotate. The second spur gear set 11 drives the rear heat sealing roller 13 to rotate synchronously. With the help of two transmission components 16, the cutting roller 15 is driven to run synchronously to ensure the coordination and continuity of the entire packaging process. When the packaging material is passively pulled out from the packaging material roll under the coordinated drive of the drive wheel 6, the shaping roller 8 and the heat sealing roller 13, the pressure roller 20 always fits tightly against the outer layer of the packaging material under the action of the return spring 21, providing constant tension control, ensuring that the packaging material remains flat during the conveying process, and will not be overstretched or loosened, thereby ensuring stable output and providing a guarantee for the subsequent packaging quality. After being guided by the guide frame 7, the pulled-out packaging material accurately enters the U-shaped plate 23 and the pressure bar 26 to form a U-shaped structure (at this time, the return spring 25 ensures that the U-shaped plate 23 is always in close contact with the pressure bar 26, providing stable forming support for the packaging material). Then, it is further shaped by two shaping rollers 8 to make the shape of the packaging material more regular, and then enters the heat sealing roller 13 area. At this time, the toothpick feeding device drops a toothpick at regular intervals, which falls accurately onto the formed packaging material. Under the synchronous rotation of the heat-sealing roller 13, multiple heat-pressing blocks 14 on its surface heat and seal the packaging material, achieving simultaneous heat sealing in both the horizontal and vertical directions. This ensures a firm seal and effectively prevents toothpicks from leaking out during subsequent storage and transportation. The sealed packaging bag continues to be conveyed to the left and enters the cutting roller 15 area for cold cutting. Finally, the finished product falls into the collection box placed in advance on the left side of the base 1, thus completing the entire packaging process from forming, shaping, filling, heat sealing to cutting of the packaging material.
