Description

Technical Field

[0001] The utility model relates to the technical field of woven bag processing, in particular to a folding component. Background Art

[0002] Woven bags are a type of plastic bag used for packaging. Conventionally, woven bags are stretched out to hold items, and folded along the creases when not in use. The creases are processed by unwinding, pressing the creases, and rewinding. The crease pressing process is to first place the woven bag outside the center frame so that the woven bag is stretched out, and then the opening on the side of the center frame is matched with the pressing wheel to form the woven bag.

[0003] The pressing wheel and its related parts can also be called folding components. Since there are errors in the processing of the woven bags themselves, the width of each one will be slightly different. Therefore, the processing errors will be adapted by using the pressing wheel in conjunction with the spring. However, the elastic force of the spring is obtained through compression, so the more compression, the greater the elastic force. If the former is too large and the latter is too small, the pressing wheel may cause damage to the woven bag due to excessive elasticity. Secondly, if the spring is not installed properly, that is, it tilts, and the spring's own elasticity changes after long-term use, it will affect the amplitude of the movement of the pressing wheel and thus affect the effect of the crease. Summary of the invention

[0004] The purpose of the utility model is to provide a folding component, which is moved by a cylinder. Since the force applied by the cylinder is balanced, the force received and the force applied by the pressure wheel during movement are also relatively balanced, so there will be no situation where the woven bag is damaged due to excessive force. Moreover, compared with the spring, the installation of the cylinder is simpler and more durable, so the problem of using the spring to achieve the movement of the pressure wheel is solved.

[0029] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-Figure 5 As shown, a folding assembly includes a pressing wheel assembly, and the pressing wheel assembly includes a mounting plate 1 and at least one pressing wheel 2, and the pressing wheel 2 is movably arranged on the mounting plate 1. Three pressing wheels 2 are generally arranged, which can be adjusted according to the length of the woven bag.

[0031] At the same time, the mounting plate 1 is provided with a slider 3 corresponding to the pressing wheel 2 , and a slide rail 4 is provided at the bottom of the pressing wheel 2 , and the slide rail 4 is connected to a cylinder 5 and moves on the slider 3 .

[0032] Therefore, in actual use, when the woven bag is larger than the set value, the woven bag will exert force on the pressure wheel 2, and the pressure wheel 2 will move outward along the slider 3. When the woven bag is smaller than the set value, the slide rail 4 moves under the drive of the cylinder 5, thereby driving the pressure wheel 2 to move inward and making the pressure wheel 2 contact with the woven bag.

[0033] Therefore, the utility model realizes movement through the cylinder 5, and because the force applied by the cylinder 5 is balanced, the pressure wheel 2 is subjected to and exerts a relatively balanced force during movement, so there will be no situation in which the woven bag is damaged due to excessive force. Moreover, compared with the spring, the cylinder 5 is easier to install and more durable.

[0034] Moreover, the pressing wheel 2 and the slide rail 4 are connected by a connecting shaft 21 , and a bearing is arranged between the pressing wheel 2 and the connecting shaft 21 , and a hand-held portion is arranged on the top of the connecting shaft 21 .

[0035] Meanwhile, the connection between the slide rail 4 and the cylinder 5 is as follows: first, a connecting plate 41 is sleeved on one end of the slide rail 4 , and the cylinder 5 is located on one side of the slider 3 and connected to the connecting plate 41 .

[0036] Secondly, the connection between the slide rail 4 and the connecting plate 41 is as follows: first, the connecting plate 41 is provided with an opening 42 for the end of the slide rail 4 to pass through, and two fasteners 43 are provided to connect the slide rail 4 and the connecting plate 41 from two directions, and the axes of the two fasteners 43 are vertically arranged.

[0037] The fastener 43 is a screw, and the stability of the connection is ensured by connecting and fixing in two mutually perpendicular directions.

[0038] like Figure 1-Figure 5 As shown, the pressure wheel assembly also includes an adjustment plate 6, and the adjustment plate 6 is arranged on the mounting plate 1, and the pressure wheel 2, the slider 3 and the cylinder 5 are all arranged on the adjustment plate 6, and the adjustment plate 6 is provided with a mounting hole 61 and an arc hole 62.

[0039] Meanwhile, the mounting plate 1 is provided with a second mounting hole 11 corresponding to the first mounting hole 61 , and the mounting plate 1 is provided with a third mounting hole 12 corresponding to the arc-shaped hole 62 .

[0040] Therefore, in actual use, the second fastener 63 passes through the first mounting hole 61 and the second mounting hole 11 to connect the adjustment plate 6 and the mounting plate 1, and the third fastener 64 passes through the arc hole 62 and the third mounting hole 12 to connect the adjustment plate 6 and the mounting plate 1, and the angle between the adjustment plate 6 and the mounting plate 1 is adjusted by the position of the third fastener 64 in the arc hole 62. The second fastener 63 and the third fastener 64 are screws.

[0041] like Figure 1-Figure 5As shown, two side plates 7 are also included, and there are two pressing wheel assemblies located between the two side plates 7, and the two pressing wheel assemblies are symmetrically arranged.

[0042] Moreover, the two pressing wheel assemblies are movably arranged between the two side plates 7 and are connected by a guide rod 8. A connecting seat 13 is arranged at the bottom of the mounting plates 1 of the two pressing wheel assemblies, and a guide rod 8 is passed through the connecting seat 13.

[0043] Therefore, in actual use, the movement of the two pressing wheel assemblies is guided by the setting of the guide rod 8. And the guide rod 8 and the connecting seat 13 are generally two so that the movement is more stable.

[0044] At the same time, the moving structures of the two pressure wheel assemblies can be the same or different. A mounting seat 14 is provided at the bottom of the mounting plate 1 of one of the pressure wheel assemblies, and a screw rod 15 is inserted into the mounting seat 14, and the mounting seat 14 and the screw rod 15 are threadedly connected.

[0045] Therefore, in actual use, the screw rod 15 is rotated to drive the mounting seat 14 to move and then drive the mounting plate 1 to move. In addition, a hand wheel is provided at one end of the screw rod 15.

[0046] Secondly, a second mounting seat 16 is provided at the bottom of the mounting plate 1 of the other pressure wheel assembly, and a second screw 17 is passed through the second mounting seat 16, and the second mounting seat 16 and the first screw 15 are threadedly connected, and a rotating rod 9 is provided between the two side plates 7, and the rotating rod 9 and the first screw 15 are connected through a transmission assembly 10.

[0047] Therefore, in actual use, when the rotating rod 9 is rotated, the screw rod 15 is rotated under the transmission of the transmission assembly 10, thereby driving the mounting seat 2 16 to move and then driving the mounting plate 1 to move. A hand wheel is provided at one end of the rotating rod 9, and the transmission assembly 10 includes two wheels and a belt.

[0048] The two pressing wheel assemblies in the drawings of the present invention are basically the same, but they adopt different moving structures. The different moving structures can place the two hand wheels on the same side for easy operation.

[0049] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. At the same time, the utility model is not limited by the above embodiments, so without departing from the principle and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model claimed for protection.
