[0002] Bag products can be seen everywhere in modern life. As one of them, small long strip packaging bags are also widely used in various fields, such as long strip bagged coffee, oral liquid, medicine, etc. The common point of these products is that the capacity of one bag is mostly a single-use dose. This packaging form provides great convenience for users to use and carry.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-Figure 3 , this application provides the following technical solutions:

[0038] A pallet reversing transmission mechanism includes a reversing frame 41 as the main supporting structure of the transmission mechanism, and a reversing pallet frame 42 is arranged on the reversing frame 41, and the reversing pallet frame 42 is used to carry the pallet to be reversingly transported. The reversing frame 41 is also provided with a first reversing mechanism 43 and a second reversing mechanism 44. The first reversing mechanism 43 is connected to the reversing pallet frame 42, and can drive the reversing pallet frame 42 to translate along a first direction; the second reversing mechanism 44 is arranged on the moving path of the reversing pallet frame 42, and can drive the reversing pallet frame 42 to translate along a second direction, and the second direction intersects with the extension line of the moving path of the first direction.

[0039] This solution is used to change the transmission path of the pallet, and can play the role of a node for changing the transmission route in the assembly line. By combining the first direction-changing mechanism 43 and the second direction-changing mechanism 44 in a single mechanism, combined with the cooperation of multiple mechanisms, a direction-changing node structure with different needs can be combined.

[0040] On the basis of the above implementation scheme, the direction-changing frame 41 includes a rectangular long shell-shaped direction-changing housing 411, and the main structural components of the first direction-changing mechanism 43 are arranged inside the direction-changing housing 411; a direction-changing support frame 412 is arranged below the direction-changing housing 411, and the direction-changing support frame 412 can be restructured according to actual needs, as long as it can stably support the direction-changing housing 411. Figure 1 As shown, the lower end of the direction-changing support frame 412 of this solution is provided with a roller group and a support block group. The support block group selects a block with a screw structure. By rotating the support block, the height position of the support block is adjusted with the help of the screw.

[0041] On the basis of the above implementation scheme, the reversing pallet rack 42 includes a reversing rack body 421 and a reversing rack positioning member 422. The length direction of the reversing rack body 421 is parallel to the movement direction of the first reversing mechanism, and the reversing rack body 421 can be linked with the first reversing mechanism 43. The reversing rack body 421 includes a bottom plate and side plates at both ends of the bottom plate in the length direction, and the reversing rack positioning members 422 are respectively arranged at the upper ends of the two side plates, and the reversing rack positioning members 422 and the upper ends of the side plates form a stepped structure. Two reversing rack positioning members 422 are symmetrically arranged on the upper part of the reversing rack body 421, and the spacing between the two reversing rack positioning members 422 corresponds to the length direction of the pallet. The two reversing rack positioning members 422 form a trumpet structure at one end facing the second reversing mechanism 44. The reversing rack body 421 is used as the main bearing structure of the pallet in the reversing conveying. The reversing frame positioning frame 422 is used as a guide and adjustment structure, so that the tray is stuck between the two reversing frame positioning members 422 when it is located on the reversing frame body 421. This ensures that the tray will not fall off when the first reversing mechanism 43 drives the reversing tray frame 42 to move as a whole. Figure 1 The figure shows that the direction-changing tray rack 42 is located at the direction-changing position of the first direction-changing mechanism 43 corresponding to the second direction-changing mechanism 44. Figure 1 Direction is reference, Figure 1 The right end of the middle redirecting rack 41 is the entrance position for the pallet to enter the mechanism, and the redirecting pallet rack 42 is there waiting for the pallet to be placed therein. How the pallet is placed on the redirecting pallet rack 42 is not the key point of the present application, and a variety of structural forms can be used to achieve this, such as using an external pushing structure to push the pallet onto the redirecting pallet rack 2, or using a robot to grab the pallet and place it.

[0042] On the basis of the above implementation scheme, the first direction-changing mechanism 43 includes a first transmission assembly 431 and a first guide assembly 432. The first transmission assembly 431 is arranged in the direction-changing housing 411, and is a conveyor belt structure, including a driving wheel, a driven wheel and a conveyor belt sleeved thereon. A block structure with a connection hole is fixedly arranged on the conveyor belt as a connection block, and also serves as the moving end of the first transmission assembly 431, and the moving end is fixedly connected to the direction-changing tray frame 42. The first guide assembly 432 includes two guide rods, which are arranged on both sides of the belt of the first transmission assembly 431.

[0043] Corresponding to the first direction-changing mechanism 43, as Figure 4 As shown, the direction-changing tray frame 42 includes a direction-changing connection seat 423, which is arranged at the lower part of the direction-changing frame body 421 of the direction-changing tray frame 42. In the structure of this solution, two direction-changing connection seats 423 are arranged, one of which is fixedly connected to the moving end of the first transmission assembly 431 in the middle, and is slidably connected to two guide rods on both sides, and the other direction-changing connection seat 423 is slidably connected to the guide rods on both sides.

[0044] This structure enables the first direction-changing mechanism 43 to transmit the direction-changing pallet rack 42 . The first direction-changing mechanism 43 drives the direction-changing pallet rack 42 to reciprocate, and the position of one pallet is transferred each time.

[0045] On the basis of the above implementation scheme, the second direction-changing mechanism 44 includes a second transmission assembly 441 and a second push frame 442. The second transmission assembly 441 is arranged on the belt side of the first transmission assembly 431. The second transmission assembly 441 uses a cylinder assembly, and the movement direction of the cylinder movable end is perpendicular to the movement direction of the first transmission assembly 431. The second push frame 442 is fixedly connected to the moving end of the second transmission assembly 441, and can push the tray on the direction-changing tray frame 42. Figure 2 As shown, the lower part of the second push frame 442 is fixedly connected to the moving end of the second transmission assembly 441, and a long horizontal plate is provided on the upper part. The length direction of the horizontal plate is parallel to the length direction of the change-direction tray frame 42, and a pad is provided on the side of the horizontal plate facing the change-direction tray frame 42.

[0046] When the direction-changing tray rack 42 is driven by the first direction-changing mechanism 43 to move to the position of the second direction-changing mechanism 44, the cylinder in the second transmission assembly 441 pushes the second push rack 442 to move, pushing the tray to direction 2. The action excitation time of the second direction-changing mechanism 44 can be based on existing technology, such as setting a photoelectric sensor, a proximity sensor, a contact switch, etc., which can provide position feedback for the direction-changing tray rack 42 as an action excitation signal for the second transmission assembly 441.

[0047] On the basis of the above implementation scheme, the changeable tray rack 42 can be further divided into an upper rack and a lower rack structure. The lower rack is connected to the first changeable mechanism 43 and can be moved laterally. The upper rack and the lower rack are rotationally connected, and a servo motor is set at the rotation point of the two as a driving power source for rotation. Under this structure, the second changeable mechanism 44 can be combined with the first changeable mechanism 43 to adopt more angles, rather than the right-angle change in the above. It is only necessary for the first changeable mechanism 43 to transport the changeable tray rack 42 to the position of the second changeable mechanism 44, and then the upper rack of the second tray rack 42 is rotated accordingly to match the angle of the second changeable mechanism 44.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
