Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to a packaging bag conveying device. Background Art

[0002] In the field of food packaging, in order to facilitate storage, transportation, sales and cost considerations, more and more foods are individually packaged in bags. This makes them easier to carry and more hygienic to eat, meeting food hygiene requirements.

[0003] The packaging bag conveyor in food packaging equipment is an indispensable part of the automated packaging production line. It is mainly responsible for conveying the food packaging bags to be packaged to the designated position of the packaging machine for subsequent filling, sealing and other packaging operations.

[0004] In the related art, the width between the bag baffles on the packaging bag conveyor is fixed, so there is a limit on the size of the food packaging bags being conveyed. Only food packaging bags of a fixed width can be conveyed, and the applicability is not strong. Summary of the Invention

[0005] The embodiment of the present application provides a packaging bag conveying device, comprising a frame and a conveyor belt, a bag baffle plate and an adjustment mechanism arranged on the frame;

[0006] There are two bag-blocking plates, which are respectively arranged on opposite sides of the conveyor belt;

[0007] The adjustment mechanism includes a rotating shaft, two bearings, two nut seats and a handwheel, the rotating shaft is connected to the frame through the two bearings, and the surface of the rotating shaft is provided with threads;

[0008] The two nut seats are symmetrically arranged and respectively connected to the bottom ends of the two bag-blocking plates. A threaded through hole is opened in the middle of the nut seat. The threaded through hole is sleeved on the rotating shaft. The threads on the threaded through hole are engaged with the threads on the surface of the rotating shaft.

[0009] The hand wheel is connected to one end of the rotating shaft.

[0010] The packaging bag conveying device of the embodiment of the present application can drive the rotating shaft to rotate by operating the hand wheel. When the rotating shaft rotates, the thread on the rotating shaft engages with the thread on the nut seat, thereby driving the two nut seats to move closer to or away from each other, and then the two nut seats respectively drive the two bag baffle plates to move closer to or away from each other. Therefore, the width between the two bag baffle plates enables the packaging bag conveying device to be suitable for more packaging bags of different widths, thereby improving the applicability of the packaging bag conveying device.

[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] Figure 1 This is a schematic structural diagram of a packaging bag conveying device provided in an embodiment of the present application; Figure 2 This is an exploded schematic diagram of a packaging bag conveying device provided in an embodiment of the present application; Figure 3 It is a structural diagram of the regulating mechanism; Figure 4 It is a structural diagram of the linkage mechanism.

[0039] See also Figures 1 to 4 As shown, an embodiment of the present application provides a packaging bag conveying device, comprising a frame 10 and a conveyor belt 20, a bag blocking plate 30 and an adjustment mechanism 40 provided on the frame 10;

[0040] There are two bag-blocking plates 30 , which are respectively arranged on opposite sides of the conveyor belt 20 . The bag-blocking plates 30 are used to prevent the packaging bags from deviating laterally from the conveyor belt 20 during transportation.

[0041] The adjustment mechanism 40 comprises a rotating shaft 41, two bearings 42, two nut holders 43, and a handwheel 44. The rotating shaft 41 is connected to the frame 10 via the two bearings 42. The surface of the rotating shaft 41 is threaded. The two nut holders 43 are symmetrically arranged and connected to the bottom ends of the two bag-blocking plates 30. A threaded through-hole is defined in the center of the nut holders 43. The threaded through-hole is sleeved onto the rotating shaft 41. The threads of the threaded through-hole engage with the threads on the surface of the rotating shaft 41. The handwheel 44 is connected to one end of the rotating shaft 41.

[0042] During use, the rotating shaft 41 can be driven to rotate by operating the hand wheel 44. When the rotating shaft 41 rotates, the threads on the rotating shaft 41 engage with the threads on the nut seat 43, thereby driving the two nut seats 43 to move closer to or away from each other, and then the two nut seats 43 respectively drive the two bag baffle plates 30 to move closer to or away from each other, so that the width between the two bag baffle plates 30 enables the packaging bag conveying device to be suitable for more packaging bags of different widths, thereby improving the applicability of the packaging bag conveying device.

[0043] Specifically, the frame 10 includes two side panels 11 and a top panel 12. The two side panels 11 are connected by multiple cross panels 13 to form a stable frame structure. The top panel 12 is connected between the two side panels 11 and is located below the bag blocking plate 30. The two bearings 42 of the adjustment mechanism 40 are respectively connected to the two side panels 11, and the shaft is installed on the bearings 42.

[0044] In this embodiment, there are multiple adjustment mechanisms 40, each spaced apart on the bag-blocking plate 30. Each adjustment mechanism 40 is connected by a linkage mechanism 50. The linkage mechanism 50 includes a first bevel gear 51 mounted on the rotating shaft 41 of each adjustment mechanism 40 and a transmission shaft 53 positioned between two adjacent linkage mechanisms 50. Each end of the transmission shaft 53 is connected to a second bevel gear 52 meshing with the first bevel gear 51. When the rotating shaft 41 rotates, it drives the first bevel gear 51, which in turn drives the second bevel gear 52, which in turn drives the transmission shaft 53. The rotation of the transmission shaft 53 in turn drives the second bevel gear 52 at the other end, which in turn drives the first bevel gear 51 on the adjacent adjustment mechanism 40. Ultimately, the position of the nut seat 43 on each adjustment mechanism 40 changes synchronously, thereby moving the two bag-blocking plates 30 closer to or farther from each other. The advantage of providing multiple adjustment mechanisms 40 is that multiple positions of the bag baffle plate 30 can be connected, so that the movement of the bag baffle plate 30 is performed simultaneously at multiple points, and the bag baffle plate 30 can change position more stably.
