Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf packing equipment, specifically, especially a tobacco leaf packing and bundling machine. Background Art

[0002] When transporting tobacco leaves, they usually need to be packed into multiple tobacco bales. In the existing packing equipment, usually, a hemp sheet is placed at the lower end inside the equipment, then the side door is closed, then loose tobacco leaves are put in, and then a second hemp sheet is covered on the upper end of the loose tobacco leaves. By using the compression action of the packing equipment, the loose tobacco leaves are compressed between the two hemp sheets, and then after bundling, the compression action can be released to take out the tobacco bale.

[0003] However, in the structure of the existing packing equipment, since the compression action moves from top to bottom and the upper end of the equipment is open, if a person's hand is not noticed and placed on the edge, a situation of pinching the hand may occur, there is a safety hazard. At the same time, after closing the side door, if the operator does not lock the side door tightly, during the compression process, the tobacco leaves are continuously pressed down and expand around, which is likely to cause the side door to open, and the compression action still continues, resulting in the tobacco leaves falling outside the equipment and the packing failing, reducing the packing efficiency.

Specific embodiments

[0022] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Combined with Figures 1 to 6 As shown in a tobacco leaf bale packing machine, including a machine body 1, a compression chamber 2 is arranged inside the machine body 1, a pressing frame 4 that can move up and down is arranged inside the compression chamber 2, an upper opening 3 is arranged at the upper end of the compression chamber 2, door closing grooves 11 are arranged at the front and rear ends of the compression chamber 2, a first anti-pressure detection device is arranged on both sides of the upper opening 3, and a second anti-pressure detection device is arranged inside the door closing groove 11; in this embodiment, the first anti-pressure detection device can detect foreign objects at the upper opening 3, so as to stop the up and down movement of the pressing frame 4, prevent the hands of operators or other foreign objects from being pressed into the compression chamber 2 by the pressing frame 4 at the edge of the upper opening 3 and cause personal injuries. Moreover, when the pressing frame 4 compresses the tobacco leaves, if the second anti-pressure detection device inside the door closing groove 11 detects that the door panel 12 is opened, the movement of the pressing frame 4 can be stopped in time to prevent the tobacco leaves from falling outside the equipment. The overall safety is higher, while reducing the safety hazards of the machine, improving the tobacco leaf packing efficiency.

[0024] On both sides of the compression chamber 2 of this embodiment, hydraulic cylinders 6 are provided. The hydraulic cylinders 6 are arranged vertically upward. The drive shafts of the hydraulic cylinders 6 on both sides are connected by a connecting rod 5, and the upper end of the pressing frame 4 is fixedly connected to the connecting rod 5. By driving the connecting rod 5 to move up and down through the hydraulic cylinder 6, the pressing frame 4 is driven to move in the compression chamber 2, so that the pressing frame 4 compresses and compacts the tobacco leaves.

[0025] On both sides of the front end and the rear end of the upper opening 3 of this embodiment, first anti-pressure detection devices are installed. The first anti-pressure detection device is a laser light curtain sensor. The laser light curtain sensor includes a light emitter 7 located at one side edge of the upper opening 3 and a light receiver 8 located at the other side edge of the upper opening 3. The light emitter 7 and the light receiver 8 correspond to each other. By detecting the edge positions on the front and rear sides of the upper opening 3 through the laser light curtain sensor, the potential safety hazard of foreign objects being pressed after reaching into the upper opening is prevented.

[0026] On the front and rear ends of the compression chamber 2 of this embodiment, side openings are provided. The closing groove 11 is arranged on the right side of the side opening. Two door panels 12 distributed vertically are hinged on the left side of the side opening. Two detection ports 16 corresponding to the door panels 12 are opened in the closing groove 11, and detection brackets 17 are installed in the detection ports 16. The second anti-pressure detection device is installed on the detection bracket 17. By detecting the closing condition through the second anti-pressure detection device, after the door panel 12 is accidentally opened, the movement of the pressing frame 4 can be stopped in time to prevent the tobacco leaves from scattering outside the equipment through the side opening.

[0027] It should be noted that the second anti-pressure detection device of this embodiment is a laser sensor. After the door panel 12 is closed, the laser sensor detects the side of the door panel 12, and this is the normal state at this time. If the door panel is opened, the laser sensor cannot detect the door panel 12, so that the movement of the pressing frame 4 can be stopped in time.

[0028] On the edge of the closing groove 11 of this embodiment, a lock seat 13 installed on the machine body 1 is provided. An axle lock assembly 14 is installed on the door panel 12. The axle lock assembly 14 includes a fixed seat 19 installed on the door panel 12. Installation plates 20 are fixedly installed at both the upper and lower ends of the fixed seat 19.

A clamping shaft cavity is arranged in the lock seat 13, and the upper end, the lower end and the front end of the clamping shaft cavity are all openings, so that the clamping shaft 21 can be clamped in the clamping shaft cavity. When the door panel 12 is closed, the clamping shaft 21 can be directly inserted into the clamping shaft cavity of the lock seat 13. By rotating the handle 23, the clamping shaft 21 rotates in the clamping shaft cavity, thereby completing the clamping, preventing the door panel 12 from being accidentally opened or preventing the door panel 12 from suddenly bouncing open during the process of compressing the tobacco leaves, which may cause personal injury, and the operation of tightly closing the door panel 12 is simpler.

[0029] Specifically, planes 25 are provided on both sides along the length direction of the clamping shaft 21, an arc surface 24 is provided between the two planes 25, the distance between the two planes 25 is smaller than the distance between the two arc surfaces 24, and the opening width at the front end of the clamping shaft cavity is the same as the distance between the two planes 25. When the door panel 12 is closed, the planes 25 on both sides of the clamping shaft 21 are rotated to correspond to the opening at the front end of the clamping shaft cavity, so that the clamping shaft 21 can directly enter the clamping shaft cavity, and then the handle is rotated to make the two arc surfaces 24 stuck inside the opening at the front end of the clamping shaft cavity, thereby preventing the door panel 12 from being accidentally opened or sprung open, making the tobacco leaves more stable during the compression and compaction processes.

[0030] In this embodiment, a plurality of first bumps 9 are provided on the lower end surface of the pressing frame 4, gaps are formed between the plurality of first bumps 9, and a plurality of second bumps 10 corresponding to the first bumps 9 up and down are provided at the inner lower end of the compression cavity 2, and gaps are formed between the plurality of second bumps 10. Before compressing the tobacco leaves, first place the binding rope in the gap between the plurality of second bumps 10, then lay the first piece of hemp sheet on the surfaces of the plurality of second bumps 10, then close the door panel 12, then place the tobacco leaves into the compression cavity 2. After the tobacco leaves are placed, cover the second piece of hemp sheet above the tobacco leaves, and then press down the pressing frame 4 to make the second piece of hemp sheet and the tobacco leaves press downwards, so as to complete the compression and compaction of the tobacco leaves. Then open the door panel 12, wind the binding rope into the gap between the plurality of first bumps 9 to complete the packaging of the tobacco bale, and then the pressing frame 4 rises and the tobacco bale can be taken out.

[0031] It should be noted that a heat dissipation hole 15 is provided on one side inside the machine body 1 of this embodiment, a cooler 18 and a hydraulic oil circulation pump 26 are installed inside the heat dissipation hole 15, and the hydraulic cylinders 6, the cooler 18 and the hydraulic oil circulation pump 26 are connected through oil pipes.
