Description

Technical Field

[0001] The utility model relates to the technical field of strapping machines, in particular to a packing belt lifting mechanism. Background Art

[0002] When packing large objects, a strapping machine is usually used for strapping. A towing head is arranged at the bottom of the strapping machine. One end of the packing belt is connected to the towing head. Under the action of the towing head, the packing belt passes through the bottom of the object and then bypasses the object from above. At this time, the object is covered by the packing belt. Finally, the two ends of the packing belt are connected together by a strapping machine. Since the towing head is arranged at the bottom of the strapping machine, one end of the packing belt returns to the operator's hand from the upper side of the object, while the other end of the packing belt needs the operator to bend down and pull it out from the bottom of the strapping machine, which is inconvenient to use, affects the packing efficiency, and increases the fatigue intensity of the operator. Content of the Utility Model

[0003] In order to solve the above problems existing in the prior art, the utility model provides a packing belt lifting mechanism with automatic lifting of the packing belt and more convenient use.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A packing belt lifting mechanism is arranged on a frame and includes a lifting rod rotatably connected to the frame, with a lifting member provided at the end of the lifting rod; a sliding seat slidably connected to the frame; a cable, one end of the cable is connected to the lifting rod; and at least two guiding members, one guiding member is arranged on the frame and the other is arranged on the sliding seat; one end of the cable is connected to the frame, and the other end of the cable bypasses the two guiding members and is connected to the lifting rod; when the towing head enters the bottom of the frame and pushes the sliding seat to move backward, the cable drives the lifting rod to lift; when the towing head at the bottom of the frame moves forward a preset distance, the cable releases the lifting rod, so that the lifting member descends to a preset position.

[0006] The packing belt is connected to the towing head. When the towing head is in the initial position inside the frame, the lifting member is in the lower position. When the towing head moves forward, it drives the packing belt to pass through the upper side of the lifting member and then separates from the frame. After the towing head finishes strapping, when the towing head enters the frame and pushes the sliding seat to move backward, the sliding seat drives the lifting rod to lift through the cable when moving backward, so as to lift the packing belt on the lifting member to the height position of the operator's hand, thus saving the action of bending down to pick up the packing belt; finally, the towing head moves forward a certain distance and resets to the initial position, and the lifting member descends to the preset position under the action of gravity.

[0007] Preferably, three guiding members are provided, namely a first guiding member, a second guiding member, and a third guiding member. The first guiding member is arranged at the upper end of the frame, the second guiding member is arranged at the lower end of the frame, and the third guiding member is arranged on the sliding seat. The other end of the cable successively bypasses the first guiding member, the second guiding member, and the third guiding member.

[0008] Preferably, the first guiding member, the second guiding member, and the third guiding member are all configured as guide wheels, and an annular groove for positioning the cable is provided on the circumferential surface of the guide wheel.

[0009] Preferably, a slide rail is provided at the bottom of the frame. The sliding seat is slidably connected to the slide rail, and a push block is fixedly provided on the sliding seat. The push block facilitates abutting against the traction head when the traction head moves backward.

[0010] Preferably, a sensor is provided at the rear end of the slide rail. When the traction head pushes the sliding seat backward until it is detected by the sensor, the traction head moves forward to the initial position. The sensor is used to limit the backward movement distance of the traction head in the frame.

[0011] Preferably, an elastic reset member for driving the lifting rod to rotate downward is provided between the lifting rod and the frame. The elastic reset member cooperates with the gravity of the lifting rod to realize the descent of the lifting rod, making the whole more stable.

[0012] Preferably, a limiting bracket is provided at the front end of the frame. A vertically distributed limiting groove is provided on the limiting bracket, and the front end of the lifting rod is arranged in the limiting groove. The limiting groove is used for limiting the lifting and lowering of the lifting rod.

[0013] Preferably, a partition is provided on the frame outside the lifting rod. The partition plays a role in safety protection.

[0014] Preferably, one end of the lifting member is connected to the front end of the lifting rod, and a protective sleeve is sleeved on the lifting member. The protective sleeve reduces the wear of the lifting member by the packing belt.

[0015] Therefore, the utility model has the beneficial effects of automatic lifting of the packing belt and more convenient use. Description of the Drawings

Features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0023] Such as Figures 1 - 5 shown, a packing belt lifting mechanism is provided on the frame 1, including a lifting rod 10, one end of the lifting rod 10 is rotatably connected to the frame 1, and a lifting member 11 is provided at the other end of the lifting rod 10; a sliding seat 20, the sliding seat 20 is slidably connected to the frame 1; a cable 30, one end of the cable 30 is connected to the lifting rod 10; and at least two guiding members, one guiding member is provided on the frame 1, and the other is provided on the sliding seat 20; one end of the cable is connected to the frame 1, and the other end of the cable bypasses the two guiding members and then is connected to the lifting rod 10; when the towing head 2 enters the bottom of the frame 1 and pushes the sliding seat 20 to move backward, the cable 30 drives the lifting rod 10 to lift; when the towing head 2 at the bottom of the frame 1 moves forward a preset distance, the cable 30 releases the lifting rod 10, so that the lifting member 11 descends to a preset position.

[0024] Wherein the end where the lifting member is located is the front end, that is Figure 2 the left end in [Figure] is the front end and the right end is the rear end.

[0025] One end of the lifting member 11 is connected to the front end of the lifting rod 10, and a protective sleeve 110 is sleeved on the lifting member 11. In some embodiments, the lifting member and the lifting rod are configured as an integral structure, and the lifting member is directly formed by bending the end of the lifting rod.

[0026] In this embodiment, three guiding members are configured, namely a first guiding member 40, a second guiding member 41, and a third guiding member 42. The first guiding member 40 is arranged at the upper end of the frame, the second guiding member 41 is arranged at the lower end of the frame, and the third guiding member 42 is arranged on the sliding seat 20. The other end of the cable 30 sequentially bypasses the first guiding member 40, the second guiding member 41, and the third guiding member 42. The first guiding member 40, the second guiding member 41, and the third guiding member 42 are all configured as guide wheels, and an annular groove for positioning the cable 30 is provided on the circumferential surface of the guide wheel. An elastic reset member 12 for driving the lifting rod 10 to rotate downward is provided between the lifting rod 10 and the frame 1. In this embodiment, the elastic reset member 12 is a tension spring.

[0027] A slide rail 21 is provided at the bottom of the frame 1. The sliding seat 20 is slidably connected to the slide rail 21, and a push block 22 is fixedly provided on the sliding seat 20; an inductor 23 is provided at the rear end of the slide rail 21. When the towing head 2 pushes the sliding seat 20 to move backward until it is detected by the inductor 23, at this time the cable drives the lifting rod to lift. Then the towing head 2 moves forward to the initial position, and the sliding seat moves forward to reset. At this time, the lifting rod rotates downward under the action of gravity and the elastic reset member, so that the lifting member descends to the preset position to prepare for the next bundling. In some embodiments, the inductor 23 can be a contact photoelectric sensor, a proximity switch, etc.

[0028] A limit bracket 50 is provided at the front end of the frame 1. A vertically distributed limit groove 51 is provided on the limit bracket 50, and the front end of the lifting rod 10 is arranged in the limit groove 51; a partition 3 is provided on the frame 1 outside the lifting rod 10.

[0029] Combined with the attached drawings, the principle of the present utility model is as follows: As Figure 2 and Figure 3 shown, when the towing head is in the initial position inside the frame, the lifting member is in the lower position. The towing head moves forward to drive the packing belt to pass through the upper side of the lifting member and then separates from the frame. After the towing head has completely passed through the belt, the towing head retracts into the frame; as Figure 5 shown, after the towing head enters the frame, it pushes the sliding seat to move backward. When the sliding seat moves backward, it drives the lifting rod to lift through the cable. At this time, the packing belt on the lifting member is lifted to the height of the operator's hand, thus eliminating the need to bend down to pick up the packing belt. When the inductor detects the signal, the towing head moves forward a certain distance to reset to the initial position, and the lifting member descends to the preset position under the action of gravity to prepare for the next bundling.

[0030] In the description of the present utility model, it should be understood that the directions or positional relationships indicated by up and down, left and right, inner end, outer end, one end, the other end, etc. are based on the orientation or positional relationship shown in the drawings, and are only for more clearly facilitating the description of the technical solution of the present utility model, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific orientation, and should not be construed as a limitation to the present utility model.

[0031] Although specific embodiments of the present utility model are described in detail herein, they are given only for purposes of explanation and should not be considered as limiting the scope of the present utility model. Various substitutions, alterations, and modifications can be conceived without departing from the spirit and scope of the present utility model.
