Description

Technical Field

[0001] This utility model relates to the technical field of packaging tissue paper flipping devices, specifically an automatic flipping device for tissue paper packaging. Background Technology

[0002] After the tissue boxes are produced, they usually need to be flipped from their horizontal position to a vertical position so that they can be packaged in the next work station.

[0003] As mentioned in the Chinese patent application CN202320521090.3 regarding an automatic flipping mechanism for tissue paper packaging: "It includes a first conveyor belt, a support platform at the output end of the first conveyor belt, a second conveyor belt on one side of the support platform, and a pushing mechanism on the support platform. This automatic flipping mechanism for tissue paper packaging first places the small packs of tissue paper produced close to the first conveyor belt in sequence. When the tissue paper is conveyed to the support platform, the motor drives the drive wheel to rotate, which in turn drives the conveyor belt to rotate. The conveyor belt drives each push rod to rotate, so that each push rod sequentially pushes each pack of tissue paper that is close to the support platform, pushing it onto the second conveyor belt. Each pack of tissue paper is guided by the adjusting guide rod, changing its position from horizontal to vertical, thereby realizing the automatic flipping of the small packs of tissue paper, avoiding the trouble of traditional manual flipping, saving manpower, and preventing omissions during manual flipping."

[0004] Through a search of the aforementioned patents, we found that this technology still has certain shortcomings in its use:

[0005] When flipping the tissue box, it needs to be conveyed by the first conveyor belt and then pushed into the second conveyor belt by the pushing mechanism after passing through the support platform. In actual operation, the tissue box movement is not smooth enough. The tissue box needs to move a certain distance on the support platform before it reaches the pushing mechanism. During the movement, the direction of the tissue box is prone to deflection, and it is very easy for jamming to occur at the junction of the support platform and the first and second conveyor belts. As a result, the tissue box cannot accurately enter the designated position of the guide rod in the subsequent process, which leads to the failure of flipping the tissue box. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic flipping device for tissue packaging, comprising a first transmission frame and a second transmission frame connected together; the first transmission frame is provided with a first transmission belt driven by a third servo motor, and the second transmission frame is provided with a second transmission belt driven by a third servo motor; a flipping assembly is provided at the connection between the first and second transmission frames, the flipping assembly including a flipping plate, a second servo motor, and a rotating rod; the power output shaft of the second servo motor is fixedly connected to the rotating rod, one end of the rotating rod is fixedly inserted through the flipping plate, the flipping plate is located inside the first transmission frame and is on the same horizontal plane as the first and second transmission belts respectively; a connecting plate is also fixed on the inner side of the first transmission frame and on one side of the first transmission belt.

[0008] As a further embodiment of this utility model: the servo motor three is mounted on one side of the transmission frame one via a fixing bracket, and a drive gear is driven to the power output shaft of the servo motor three, and a driven gear meshes with the drive gear; both sides of the inside of the transmission belt one are provided with a drive shaft one, and the two ends of the drive shaft one are rotatably connected to the two sides of the inner wall of the transmission frame one, and one end of one of the drive shafts one passes through the transmission frame one and is fixedly connected to the driven gear.

[0009] As a further embodiment of this utility model: the servo motor is installed on one side of the transmission frame 2, and the transmission belt 2 is provided with two transmission shafts 2 inside each side. The two ends of the transmission shaft 2 are rotatably connected to the two sides of the inner wall of the transmission frame 2, and one end of the transmission shaft 2 movably passes through the transmission frame 2 and is connected to the power output shaft of the servo motor 1.

[0010] As a further embodiment of this utility model: the second servo motor is installed in the inner cavity on one side of the second transmission frame, and the end of the rotating rod away from the second servo motor is rotatably connected to the inner cavity of the first transmission frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this application, the designed transfer rack 1, transfer rack 2, flipping mechanism, and connecting plate structure enable the connection between transfer rack 1 and transfer rack 2. With the flipping plate, multiple packs of tissue paper can be transferred from transfer rack 1 to transfer rack 2 at one time, and flipped from a horizontal state to a vertical state for subsequent packaging, resulting in higher efficiency. During this process, the overlapping of the connecting plate between the flipping plate and transfer belt 1 eliminates jamming areas, and the flipping plate slides and fits against transfer belt 2, which can prevent the tissue paper from jamming during movement. Ultimately, this effectively improves the smoothness of tissue paper movement and ensures normal flipping of the tissue paper. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 An automatic flipping device for tissue packaging includes a transmission frame 1 and a transmission frame 3 connected together. The transmission frame 1 has a transmission belt 2 driven by a servo motor 3 9, and the transmission frame 3 has a transmission belt 4 driven by a servo motor 1 5. A flipping assembly 7 is provided at the connection between the transmission frame 1 and the transmission frame 3. The flipping assembly 7 includes a flipping plate 701, a servo motor 2 702, and a rotating rod 703. The power output shaft of the servo motor 2 702 is fixedly connected to the rotating rod 703. One end of the rotating rod 703 is fixedly inserted through the flipping plate 701. The flipping plate 701 is located inside the transmission frame 1 and is on the same horizontal plane as the transmission belt 2 and the transmission belt 2 4. A connecting plate 6 is also fixed inside the transmission frame 1 and located on one side of the transmission belt 2.

[0027] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the servo motor 39 is mounted on one side of the transmission frame 1 via the fixing bracket 8. The power output shaft of the servo motor 39 is connected to the drive gear 10, and the drive gear 10 is meshed with the driven gear 11. Both sides of the inside of the transmission belt 2 are provided with drive shafts 201. The two ends of the drive shafts 201 are rotatably connected to the two sides of the inner wall of the transmission frame 1, and one end of one drive shaft 201 passes through the transmission frame 1 and is fixedly connected to the driven gear 11.

[0028] Specifically, after the servo motor 39 starts, the drive gear 10 can drive the driven gear 11 that meshes with it to rotate. After the driven gear 11 rotates, it can drive the transmission shaft 201 connected to it to rotate, thereby driving the transmission belt 2 to move. In order to make the transmission belt 2 have the effect of intermittent movement, the drive gear 10 can be set as an incomplete gear. Only when the teeth of the incomplete gear mesh with the driven gear 11 can the transmission belt 2 be driven to move.

[0029] Please see Figure 1 and Figure 3In this embodiment, the servo motor 5 is installed on one side of the transmission frame 3. The transmission belt 4 is equipped with two transmission shafts 401 inside. The two ends of the transmission shafts 401 are rotatably connected to the two sides of the inner wall of the transmission frame 3. One end of one of the transmission shafts 401 passes through the transmission frame 3 and is connected to the power output shaft of the servo motor 5.

[0030] Specifically, after the servo motor 5 starts, it drives the transmission shaft 401 connected to it to rotate using its power output shaft, thereby driving the transmission belt 4 connected to the transmission shaft 401 to move, and finally driving the paper on the transmission belt 4 to move in a vertical position.

[0031] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the second servo motor 702 is installed in the inner cavity on one side of the second transmission frame 3, and the end of the rotating rod 703 away from the second servo motor 702 is rotatably connected to the inner cavity of the first transmission frame 1.

[0032] Specifically, after the servo motor 702 is started, it can drive the rotating rod 703 to rotate using its power output shaft. When the rotating rod 703 rotates, it can drive the flip plate 701 fixed to it to perform a flipping action.

[0033] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the bottom side of the connecting plate 6 is designed as an arc and slides against the conveyor belt 2. The other side of the connecting plate 6 slides against the flip plate 701. The top of the connecting plate 6 and the top of the flip plate 701 are on the same horizontal plane. The top surface of the connecting plate 6 and the top surface of the flip plate 701 are both designed as smooth mirror structures.

[0034] Specifically, the two sides of the connecting plate 6 are slidably attached to the conveyor belt 2 and the flip plate 701 respectively, and the top is on the same horizontal plane, so that an overlapping effect can be formed between the conveyor belt 2 and the flip plate 701, making up for the gap formed at the connection, thereby eliminating the problem of paper pulling jamming, which can facilitate better paper pulling. The top surface of the connecting plate 6 and the top surface of the flip plate 701 are both designed with a smooth mirror structure, which can improve the paper pulling movement effect.

[0035] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, both sides of the flip plate 701 are designed as arc surfaces. The arc surface of one side of the flip plate 701 slides and fits against the second conveyor belt 4. The bottom of the arc surface of the other side of the flip plate 701 is fitted with a positioning plate 12, which is fixed to the inner wall of the first conveyor frame 1.

[0036] Specifically, since the flip plate 701 needs to rotate, the two sides of the flip plate 701 are designed as arc surfaces. This can prevent jamming with the side of the second conveyor belt 4 and the inner wall of the first conveyor frame 1 during movement, thus ensuring the smoothness of the flip plate 701 when flipping. A positioning plate 12 is also provided on the inner wall of the first conveyor frame 1, which can make the flip plate 701 accurately reset and facilitate the subsequent paper feeding.

[0037] When using:

[0038] Servo motor 39 drives the movement of conveyor belt 12, and servo motor 15 drives the movement of conveyor belt 24. Multiple packs of tissues are transported via conveyor belt 12 and can slide on connecting plate 6 to the top of flip plate 701. When flip plate 701 has... Figure 6 After the three packs of tissues are shown, the conveyor belt 2 stops its transmission action, the servo motor 702 starts to drive the rotating rod 703 to rotate, the rotating rod 703 rotates the flipping plate 701 to rotate, thereby flipping the tissues on the flipping plate 701 from a horizontal state to a vertical state. After the tissues are flipped, they will fall directly into the conveyor frame 3 and be transported backward by the conveyor belt 4 in the conveyor frame 3.

[0039] After the flip plate 701 completes one flip, the power output shaft of the servo motor 702 reverses, thereby driving the flip plate 701 back to the initial position, waiting for the conveyor belt 2 to transfer the subsequent paper to the flip plate 701 for the next flip.

[0040] In operation, this application mainly consists of three steps: first, the conveyor belt 2 transports the tissue paper to the flipping plate 701; second, the flipping plate 701 flips the tissue paper and returns it to its initial position to await the next flip; and third, the flipped tissue paper is transported into subsequent operations via the conveyor belt 4. In this application, the entire flipping process is smoother than the prior art and the flipping efficiency of the tissue paper is higher.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
