Description

TECHNICAL FIELD

[0001] The utility model relates to leafy plant packaging equipment technical field, especially a tobacco leaf bale turnover device. BACKGROUND

[0002] Leafy plant agricultural products, such as tobacco leaves, kelp, etc., due to the loose and bulky volume, thus, after being purchased at the production base, they usually need to be weighed, compressed, transported and packed, and then transported to the processing plant for storage. In the prior art, the traditional packaging is wrapped and tied with hemp pieces. In recent years, there has been a way of squeezing compressed materials into a hemp bag for tying or sewing. This packaging method requires that, during the bale-out process, the material bale squeezed out of the squeezing and compressing equipment is first squeezed into a turnover device for turnover processing, and then tied or sewn. After tying or sewing is completed, it also needs to be turned over in the opposite direction to complete the final bale-out action. At the same time, in order to connect with the squeezing and bale-out equipment, it also needs to be horizontally translated for a short distance when turned over to the horizontal state.

[0003] At present, there are various structural forms of products on the market for this kind of turnover device, but they all have the disadvantages of complex structure, etc. Especially, the turnover and translation are driven by chain sprocket or gear pair, which needs to be equipped with a travel switch or a sensor to control the travel. Once the travel switch or the sensor fails, it will cause damage to the equipment, thus, the equipment has safety hazards.

The turnover bale receiving tube is arranged at the discharge port of the tobacco bale packaging equipment. When the tobacco bale is pushed out, it falls into the bale receiving tube. After turnover, it is convenient for workers to sew the bale, which solves the problem that after the tobacco bale is pushed out of the discharge port, it will expand due to the reduction of the pressure, which will affect the subsequent sewing. At the same time, the bale receiving tube can move forward in the bale receiving state, which ensures the connection with the discharge port of the packaging equipment and improves the bale receiving smoothness.

Figure 1When the end of the front and rear turning oil cylinder shaft 15 of the front and rear turning oil cylinder 11 (as shown in the figure) extends out and pushes the joint bearing 17 to move to the left, at this time, the whole bale bucket 20 turns counterclockwise around the axis of the turning translation shaft 29, and at the same time, moves to the left along with the turning translation wheel 31 in the slot of the turning translation slot 13, and further causes the turning guide wheel 34 to turn to the right and up along the slot of the turning guide slot 14; when the turning guide wheel 34 turns from the slot of the turning guide slot 14 to the slot of the turning translation slot 13, the bale bucket 20 is in a horizontal state, then the bale bucket 20 continues to translate to the left for a short distance, so that the upper end port of the bale bucket 20 is in contact with the extrusion port of the extrusion type compression, packaging and discharging equipment (at this time, the extension stroke of the front and rear turning oil cylinder shaft 15 of the front and rear turning oil cylinder 11 reaches the limit and remains stationary), then the weighed and compressed tobacco bale is extruded from the extrusion port and directly extruded into the burlap bag sleeved on the extrusion port, and at the same time, due to the contact between the extrusion port and the upper end port of the bale bucket 20, the tobacco bale is directly extruded into the bale bucket 20, and at the same time, the packing rope is extruded into the rope placing slot 23 of the bale bucket 20, thus the bale receiving action of the bale bucket 20 is completed. Then the front and rear turning oil cylinder 11 works reversely, the end of the front and rear turning oil cylinder shaft 15 of the front and rear turning oil cylinder 11 which extends to the left drives the joint bearing 17 to move to the right, and at the same time, the bale bucket 20, the turning translation wheel 31 and the turning guide wheel 34 move to the right in the slot of the turning translation slot 13; when the turning guide wheel 34 moves to the upper end of the turning guide slot 14, the turning guide wheel 34 enters the slot of the turning guide slot 14 and turns to the left and down along the slot, and further drives the bale bucket 20 to turn clockwise around the axis of the turning translation shaft 29; when the bale bucket 20 turns to a vertical state, the retraction stroke of the front and rear turning oil cylinder shaft 15 of the front and rear turning oil cylinder 11 reaches the limit and remains stationary, and then the bale is tied or sewed. Then the front and rear turning oil cylinder 11 works again (at the same time, the packing rope is placed at the rope placing slot 23 of the upper end port of the bale bucket 20), when the bale bucket 20 is in a horizontal state again, the extrusion type compression, packaging and discharging equipment extrudes the weighed and compressed tobacco bale from the extrusion port and directly extrudes it into the burlap bag sleeved on the extrusion port, and at the same time, the tobacco bale sleeved in the burlap bag is extruded to the upper end port of the bale bucket 20, and further extrudes the bale which has been tied or sewed and is still placed in the inner cavity of the bale bucket 20 to the lower end port (at this time, the position can be regarded as the right end port) of the bale bucket 20 and falls on the bale discharging roller 3 of the bale discharging roller assembly. Since the front and rear support rods 2 are installed in a left-high and right-low manner, the tobacco bale falling on the bale discharging roller 3 will automatically roll to the right end and slide out under the action of gravity, thus the bale discharging action is completed. Repeating the above actions can realize the continuous operation of bale receiving, tying and bale discharging.

[0066] Example 2:

[0067] This example is a special case of Example 1 (see the attachedFigure 8 The difference between the embodiment 1 and the embodiment 2 is that the embodiment 2 replaces the delivery cylinder assembly in the embodiment 1 with a delivery assembly which is composed of front and rear support rods 2 and a delivery chute 38.

The delivery chute 38 is laid on the top of the front and rear support rods 2 on the left and right sides, and the top of the delivery chute 38 is smooth like a mirror surface.

[0068] The other parts are the same as those in the embodiment 1.

[0069] The use process of the embodiment 2 is basically the same as that of the embodiment 1, except that when the baled or sewn tobacco leaf package is pushed to the lower end of the delivery cylinder 20 (the position can be regarded as the right end of the delivery cylinder 20), and falls on the delivery chute 38 of the delivery assembly, due to the left-high right-low installation of the front and rear support rods 2 and the smooth mirror surface of the top of the delivery chute 38, the resistance is extremely small, so that the tobacco leaf package falling on the delivery chute 38 will automatically slide to the right end under the action of gravity, thereby completing the delivery action. Repeating the above action can realize the continuous operation of the receiving, binding and delivery.

[0070] The other parts are the same as those in the embodiment 1, and will not be described here.

[0071] Embodiment 3:

[0072] The embodiment 3 is another special case of the embodiment 1 (see the attached drawings). Figure 9The difference between the embodiment 1 and the embodiment 2 (as shown in the figure) is that the embodiment 1 is replaced by the embodiment 2, wherein the delivery assembly of the embodiment 2 is composed of the front and rear support plates 44, the driving roller 43, the driven roller 46, the conveying belt 39, the driving roller shaft 42, the driven roller shaft 47, one or more than one supporting roller 41, the speed reducer motor 40, the supporting beam 48, the positioning bracket 45, and the matched roller bearing seat and supporting roller bearing seat; the right end and the left end of the front and rear support plates 44 are respectively clamped with the front and rear ends of the driving roller 43 and the driven roller 46, and the front and rear ends of the driving roller shaft 42 and the driven roller shaft 47 are respectively inserted into the roller bearing seats (not shown in the figure) installed on the left and right ends of the front and rear support plates 44; the speed reducer motor 40 is arranged at the right rear part of the rear support plate 44, and the rear end of the driving roller shaft 42 is directly inserted into the speed reduction output shaft hole (not shown in the figure) of the speed reducer motor 40 after passing through the roller bearing seat; the front and rear ends of the supporting roller 41 are inserted into the supporting roller bearing seats (not shown in the figure) arranged on the front and rear support plates 44; the supporting beam 48 for supporting the left end of the front and rear support plates 44 is arranged on the right side of the left part of the right vertical column 12 of the frame; the positioning bracket 45 for clamping and positioning and preventing the left and right direction movement is in the shape of “M” and is arranged at the right lower part of the front and rear support plates 44, and the lower clamping hole is clamped on the right longitudinal beam (not marked in the figure) of the base frame 1; the conveying belt 39 is wound between the driving roller 43 and the driven roller 46 to form a cycle.

[0073] The other parts are the same as those of the embodiment 1.

[0074] The use process of the embodiment 2 is basically the same as that of the embodiment 1, except that the speed reducer motor 40 is started to drive the clockwise cycle of the conveying belt 39 around the driving roller 43 and the driven roller 46 when the packing starts.

[0075] When the baled or packed tobacco leaves are pushed to the lower end of the bale outlet barrel 20 (at this time, the position can be regarded as the right end), and fall on the conveying belt 39 of the delivery assembly, since the conveying belt 39 is in clockwise cycle from the beginning, at this time, the tobacco leaves falling on the conveying belt 39 are carried by the conveying belt 39 from the left end to the right end, so as to complete the bale delivery action. The above-mentioned action is repeated to realize the continuous operation of bale receiving, baling and bale delivery.

[0076] The other parts are the same as those of the embodiment 1, which will not be repeated here.
