[0001] This utility model relates to the field of bag-applying machine technology, specifically to a flipping structure of a bag-applying machine folding mechanism. Background Technology

[0002] The patch pocket machine is mainly used for sewing pockets on clothing such as jeans, work clothes, and shirts. It can complete flat stitching and buttonhole stitching in one go and is suitable for sewing back pockets of various jeans, work clothes pockets, and shirt pockets.

[0003] Application publication number CN110184754A discloses an automatic intelligent bag-applying machine and a bag-applying method. Specifically, the automatic intelligent bag-applying machine includes a frame standing on the ground, and further includes: a work platform, fixedly installed on the frame, used for adsorbing the bottom layer fabric and for sewing the fabric, having an adsorption and shaping area and a sewing area; a pocket fabric folding mechanism, located above the adsorption and shaping area and fixedly installed on the frame, used for supporting, positioning, adsorbing, folding, and placing the pocket fabric; and a fabric pressing and moving mechanism, installed on the frame, used for switching back and forth between the adsorption and shaping area and the sewing area, pressing the outer and inner edges of the fabric, pressing the fabric onto the work platform for planar movement, and taking material from the adsorption and shaping area to the sewing area for double-line sewing by the sewing machine. The pocket fabric folding mechanism includes a lifting cylinder fixed to the frame, a hinge frame structure driven by the lifting cylinder, an electromagnetic adsorption device fixed to the hinge frame structure, a folding mechanism, and a tongue positioning mechanism located on the hinge frame structure for telescopic movement. The tongue positioning mechanism places and positions the pocket fabric. The hinge frame structure drives the electromagnetic adsorption device to adsorb the tongue positioning mechanism and clamp the pocket fabric between them. The folding mechanism folds the pocket fabric. The lifting cylinder drives the folding mechanism to move downwards and place the folded pocket fabric on the bottom layer of fabric. The hinge frame structure resets and drives the electromagnetic adsorption device and the folding mechanism to move away from the tongue positioning mechanism. The electromagnetic adsorption device and the tongue-pressing positioning mechanism have a concave-convex contact surface that allows for controllable adsorption via electromagnetic force. The tongue-pressing positioning mechanism includes a telescopic rod that extends longitudinally relative to the hinge frame structure, a positioning adsorption block that further extends and retracts on the telescopic rod and is connected to a positive pressure air supply device, and a tongue-pressing piece connected to the end of the telescopic rod and cooperating with the positioning adsorption block for adsorbing the pocket fabric. The pocket fabric is placed on the tongue-pressing piece, and the positioning adsorption block is close to the edge of the pocket fabric and adsorbs the pocket fabric through negative pressure. The electromagnetic adsorption device is fixed to the folding frame, and the folding frame is fixed to the hinge frame, thereby adsorbing and clamping the pocket fabric. The hinge frame structure includes a fixed frame, a hinge cylinder, a gantry base, and a swing arm frame. The hinge cylinder is hinged to both sides of the fixed frame, the gantry base is fixed to the fixed frame, and the swing arm frame is connected to the gantry base. The tail end of the swing arm frame is connected to the telescopic rod of the hinge cylinder, and the hinge cylinder drives the swing arm frame to swing on the gantry base.

[0004] Although the folding mechanism in the aforementioned automatic intelligent bag-sealing machine can rotate and swing, it is necessary to provide another structure that allows the folding mechanism to move up and down and rotate up and down to meet different market demands in order to adapt to the continuous development of the market.

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a flipping structure for the folding mechanism of a bag-applying machine, which can be used to drive the folding mechanism to stably achieve up-and-down movement and flipping.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A flipping structure for a folding mechanism of a bag-applying machine includes a positioning seat, a folding mechanism, and a flipping assembly. The positioning seat is fixedly installed. The flipping assembly includes a flipping cylinder, a movable plate, a connecting shaft, two flipping plates, and two guide rods. The flipping cylinder is fixed on the positioning seat. The movable plate is movably mounted on the positioning seat and connected to the output shaft of the flipping cylinder. The connecting shaft is connected to the movable plate. The lower ends of the two flipping plates are movably sleeved on both ends of the connecting shaft. The bottoms of the two flipping plates are connected to the folding mechanism. A curved track groove is provided on both sides of the positioning seat. One end of each of the two guide rods is correspondingly connected to the upper end of the two flipping plates, and the other ends of the two guide rods are matched and inserted into the two track grooves. When the movable plate is driven to move up and down by the flipping cylinder and the connecting shaft is moved up and down synchronously, the guide rods can slide in the track grooves through the flipping plates, thereby realizing the stable up and down movement and flipping of the folding mechanism.

[0007] Furthermore, the flipping assembly also includes a downward pressing cylinder; the downward pressing cylinder is fixed to the movable plate and its output shaft is connected to the connecting shaft.

[0008] Furthermore, the flipping assembly also includes two supports; the two supports are respectively mounted on the connecting shaft; the output shaft of the pressing cylinder is connected to the two supports respectively. By setting the supports, the pressing cylinder can be stably connected to the connecting shaft.

[0009] Furthermore, a first slide rail assembly is provided between each of the supports and the movable plate; the first slide rail assembly includes a first slide rail connected to the movable plate and a first slider connecting the first slide rail and the support respectively. This arrangement allows the connecting shaft to move more stably up and down.

[0010] Furthermore, two hydraulic dampers are also provided on the positioning seat; the two hydraulic dampers are respectively located above the two first sliders and cooperate with the two first sliders respectively. The above arrangement can prevent the first slider from exceeding the preset stroke.

[0011] Furthermore, a second slide rail assembly is provided between the movable plate and the positioning seat; the second slide rail assembly includes a second slide rail connected to the movable plate and a second slider connecting the second slide rail and the positioning seat respectively. This arrangement allows the movable plate to move more stably up and down.

[0012] Furthermore, a through hole is provided at the lower end of each of the flip plates; the flip plate is sleeved on the connecting shaft through the through hole, and a bearing is provided between the connecting shaft and the side wall of the through hole. This arrangement facilitates a convenient movable connection between the flip plate and the connecting shaft.

[0013] Furthermore, the track groove includes an inclined section at the top and a vertical section at the bottom, thereby enabling the folding mechanism to perform different actions.

[0014] Furthermore, the movable plate is connected to the output shaft of the tilting cylinder by a connecting plate, which facilitates the connection between the tilting cylinder and the movable plate.

[0019] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0020] like Figures 1-6 As shown, a flipping structure for a folding mechanism of a bag-applying machine includes a positioning seat 1, a folding mechanism 2, and a flipping assembly 3. The positioning seat 1 is fixedly installed.

[0021] The flipping assembly 3 includes a flipping cylinder 31, a movable plate 32, a connecting shaft 33, two flipping plates 34, and two guide rods 35.

[0022] Specifically, the tilting cylinder 31 is fixed on the positioning seat 1; the movable plate 32 is movably mounted on the positioning seat 1 and is connected to the output shaft of the tilting cylinder 31; the connecting shaft 33 is connected to the movable plate 32; the lower ends of the two tilting plates 34 are respectively movably sleeved on both ends of the connecting shaft 33; the bottom of the two tilting plates 34 are respectively connected to the folding mechanism 2; a curved track groove 11 is respectively provided on both sides of the positioning seat 1; one end of the two guide rods 35 is respectively connected to the upper end of the two tilting plates 34, and the other end of the two guide rods 35 is respectively matched and inserted into the two track grooves 11.

[0023] During use, when the rotating cylinder 31 drives the movable plate 32 to move up and down and synchronously drives the connecting shaft 33 to move up and down, the rotating plate 34 can drive the guide rod 35 to slide in the track groove 11, thereby realizing the stable up and down movement and up and down flipping of the folding mechanism 2.

[0024] In summary, the overall structure of this utility model is simple and reasonable. Through the cooperation of the flipping cylinder 31, the movable plate 32, the flipping plate 34, the connecting shaft 33, and the guide rod 35, the folding mechanism 2 can be stably driven to move up and down and flip up and down. Specifically, by using the track groove 11, the folding mechanism 2 can accurately perform the corresponding actions, that is, the accuracy of the folding mechanism 2's actions is guaranteed.

[0025] like Figures 1-5 As shown, in this embodiment, the flipping assembly 3 also includes a pressing cylinder 36; the pressing cylinder 36 is fixed on the movable plate 32 and its output shaft is connected to the connecting shaft 33. Therefore, by setting the pressing cylinder 36, after the flipping cylinder 31 drives the folding mechanism 2 to move downward and flip a certain distance, the pressing cylinder 36 can continue to drive the connecting shaft 33 to move downward a certain distance. This allows the flipping plate 34 to drive the guide rod 35 to continue moving downward a certain distance in the track groove 11, thereby driving the folding mechanism 2 to move downward a certain distance. This makes the folding mechanism 2 more stably pressed onto the pocket fabric. Of course, due to the setting of the pressing cylinder 36, when the flipping cylinder 31 drives the guide rod 35 to move downward, the guide rod 35 will not move to the bottom of the track groove 11, so as to reserve space for the pressing cylinder 36 to continue driving the folding mechanism 2 to move.

[0026] like Figures 1-5 As shown, the flipping assembly 3 also includes two supports 37; the two supports 37 are respectively mounted on the connecting shaft 33; the output shaft of the pressing cylinder 36 is connected to the two supports 37 respectively. Therefore, the connecting shaft 33 is connected to the movable plate 32 through the pressing cylinder 36 and the supports 37. In addition, by setting the supports 37, the pressing cylinder 36 can be stably connected to the connecting shaft 33.

[0027] like Figure 3 As shown, a first slide rail assembly is provided between each support 37 and the movable plate 32; the first slide rail assembly includes a first slide rail 38 connected to the movable plate 32 and a first slider 39 connecting the first slide rail 38 and the support 37 respectively. Therefore, after setting the first slide rail 38 and the second slider 39, the connecting shaft 33 can be more stable when moving up and down, and the accuracy of the folding mechanism 2 during operation can also be guaranteed.

[0028] like Figure 3 As shown, two hydraulic buffers 40 are also provided on the positioning seat 1; the two hydraulic buffers 40 are respectively located above the two first sliders 39 and cooperate with the two first sliders 39 respectively. By setting the hydraulic buffers 40, the first sliders 39 can be limited when they move upward, so as to prevent the first sliders 39 from exceeding the preset stroke, that is, to prevent the folding mechanism 2 from exceeding the preset stroke.

[0029] like Figure 4 As shown, a second slide rail assembly is also provided between the movable plate 32 and the positioning seat 1; the second slide rail assembly includes a second slide rail 41 connected to the movable plate 32 and a second slider 42 connecting the second slide rail 41 and the positioning seat 1 respectively. Similarly, by providing the second slide rail 41 and the second slider 42, the movement stability of the movable plate 32 can be ensured, thereby ensuring the accuracy of the folding mechanism 2 during operation.

[0030] like Figure 4 As shown, each flip plate 34 has a through hole 43 at its lower end; the flip plate 34 is sleeved on the connecting shaft 33 through the through hole 43, and a bearing 44 is provided between the connecting shaft 33 and the side wall of the through hole 43. The above arrangement can easily realize the movable connection between the flip plate 34 and the connecting shaft 33.

[0031] like Figures 4-5 As shown, the track groove 11 includes an inclined section at the top and a vertical section at the bottom, which allows the guide rod 35 to move within the track groove 11 and enables the folding mechanism 2 to perform different actions. For example, when the guide rod 35 moves in the inclined section, the folding mechanism 2 can move up and down and also flip up and down, while when the guide rod 35 moves to the vertical section, the folding mechanism 2 will only move up and down.

[0032] like Figure 2 As shown, in this embodiment, the movable plate 32 and the output shaft of the tilting cylinder 31 are connected by a connecting plate 45, so that the tilting cylinder 31 can easily drive the movable plate 32 to move up and down.

[0033] The folding mechanism 2 is used to fold the pocket fabric. The specific structure of the folding mechanism 2 includes a mounting plate connected to the flipping plate 34, a pressing plate mounted on the mounting plate, and multiple folding components, each of which includes a folding piece and a folding cylinder. Since the folding mechanism 2 is existing technology, it will not be described in detail here. In addition, a feeding mechanism 4 is provided below the folding mechanism 2 to cooperate with it. This feeding mechanism 4 includes a feeding template for placing the pocket fabric.

[0034] Combination Figure 6 The following describes the specific working principle of this utility model in order to help you understand it: First, the positioning seat 1 is fixed on the frame. When the folding mechanism 2 is to be driven to flip downwards, the flipping cylinder 31 drives the movable plate 32 downwards, causing the connecting shaft 33, the flipping plate 34, and the guide rod 35 to move downwards accordingly. As the guide rod 35 moves in the inclined section, it causes the folding mechanism 2 to gradually move downwards and flip downwards. When the guide rod 35 moves in the vertical section, the folding mechanism 2 moves directly downwards, at which point the flipping is complete. The folding mechanism 2 stops when it reaches the corresponding position on the feeding mechanism 4. Then, the pressing cylinder 36 drives the connecting shaft 33 downwards, simultaneously moving the folding mechanism 2 downwards a certain distance, allowing the pressing plate of the folding mechanism 2 to better press against the pocket fabric on the feeding template of the feeding mechanism 4. Next, the folding mechanism 2 can perform the folding operation on the pocket fabric. After the folding is completed, all components are reset. First, the pressing cylinder 36 drives the folding mechanism 2 to rise a certain distance, that is, the pressing plate releases the pocket fabric. Then, the flipping cylinder 31 drives the folding mechanism 2 to rise a certain distance. When it continues to rise, it will flip upwards at the same time until the guide rod 35 moves into place, and then the flipping cylinder 31 stops.

[0035] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
