Description

Technical Field

[0001] The utility model relates to the technical field of cigarette box packaging, in particular to an adjustable cigarette box pushing device with an overload protection structure. Background Art

[0002] As the star product of Shanghai Tobacco Factory, the side-opening "Jin Zhongzhi" brand cigarettes have been favored by consumers since they were launched on the market. With the substantial increase in the consumption of "Jin Zhongzhi" cigarettes in the market, Shanghai Tobacco Factory introduced the new side-opening 200-pack-per-minute ZB417C cigarette packaging prototype unit developed by Shanghai Tobacco Machinery Company.

[0003] During the actual debugging and production process, the box frequently got stuck at the terminal output position of the CV equipment, causing the box pusher to be blocked and the resistance to be directly transmitted back to the main gearbox, resulting in damage to the transmission gear and subsequent shutdown for repair. In serious cases, there were three damages in a single month, and each damage required three maintenance workers to spend at least 5 hours to repair, which seriously affected the production efficiency of Jinzhongzhi products.

[0004] See also Figure 1 The main reason for the obstruction of the output of the bar box is that under the action of the lifting mechanism 02, the bar boxes are laterally aligned with the existing push plate 01 one by one. Since the existing push plate 01 is integrally formed, when the bar box queue is blocked, the extrusion force between the existing push plate 01 and the bar box is transmitted back to the main gear box, causing damage to the transmission gear and then stopping for repair. Utility Model Content

[0005] In view of the shortcomings of the prior art mentioned above, the technical problem to be solved by the utility model is to provide an adjustable bar box pushing device with an overload protection structure, which can solve the problem that the existing bar box pusher cannot unload force due to obstruction, protect the key parts of the equipment from damage, reduce the equipment accidents caused thereby, and improve the production efficiency of the equipment.

[0006] In order to solve the above technical problems, the utility model provides an adjustable box pushing device with an overload protection structure, comprising:

[0007] Drive device;

[0008] A bracket, the bracket is drivingly connected to the driving device to perform horizontal linear motion;

[0009] A flip push plate for pushing the strip box, wherein the upper and lower sides of the flip push plate are respectively an upper side and a lower side, and the upper side is rotatably arranged on the bracket;

[0010] The overload protection structure includes a mounting tube arranged on the bracket, a resistance adjustment rod extending into the mounting tube, a resistance bead movably arranged in the mounting tube, and a compression elastic member arranged in the mounting tube. The mounting tube has a transversely penetrating tube cavity, and the tube cavity is in a reduced shape at one end close to the flip push plate. The resistance adjustment rod extends into the mounting tube through the tube cavity at the other end away from the flip push plate, and the length of the resistance adjustment rod extending into the tube cavity is adjustable. A part of the resistance bead is exposed from the mounting tube to abut against the edge of the flip push plate, and the two ends of the compression elastic member along its own compression direction abut against the resistance adjustment rod and the resistance bead respectively.

[0011] When the horizontal force applied by the box to the flip push plate is not greater than the preset force, the edge of the flip push plate is always blocked by the resistance beads to be in an upright state;

[0012] When the horizontal force applied by the box to the flip push plate is greater than the preset force, the flip push plate swings upward after overcoming the resistance of the resistance bead.

[0013] Furthermore, the adjustable box pushing device with an overload protection structure also includes a sensor and a sensed object, the sensor is arranged on the bracket and is communicatively connected to the driving device, the sensed object is arranged on the flip push plate, the sensor is moved away from the sensed object after the flip push plate is flipped, or the sensor is moved close to the sensed object after the flip push plate is flipped.

[0014] Furthermore, the overload protection structure also includes a nut, which is arranged on the bracket and is threadably matched with the resistance adjustment rod.

[0015] Furthermore, the compression elastic member is a compression spring.

[0016] Furthermore, an inner polygonal hole is provided on the end of the resistance adjustment rod extending out of the mounting tube.

[0017] Furthermore, the bracket includes a base, a vertical plate, a horizontal plate and a suspension plate which are connected in sequence, and the suspension plate and the flip push plate are hinged to each other.

[0018] Furthermore, a first reinforcing rib is provided between the base and the vertical plate; and / or a second reinforcing rib is provided between the vertical plate and the horizontal plate.

[0019] Furthermore, the suspension plate is detachably connected to the cross plate via a connecting assembly.

[0020] Furthermore, the suspension plate is in the form of a trough structure with an opening facing downward, and the suspension plate includes a trough bottom, a first trough wall portion, and a second trough wall portion, and the spacing between the first trough wall portion and the second trough wall portion is adapted to the width of the flip push plate; the overload protection structure is arranged in one of the first trough wall portion and the second trough wall portion.

[0021] Furthermore, the resistance ball is a steel ball.

[0022] As described above, the adjustable bar box pushing device with an overload protection structure of the utility model has the following beneficial effects: the adjustable bar box pushing device of the utility model changes the integrated bar box push plate in the prior art into a flip push plate with adjustable resistance, which is used to solve the problem in the prior art that the transmission gear is damaged because the bar box pusher is blocked and cannot unload force. The height of the cantilevered side of the bracket is higher than the height of the bar box to be pushed, forming the basic spatial condition for the flip push plate to disconnect the resistance conduction path. The upper side of the flip push plate is rotatably arranged on the bracket, and a rotating shaft can be added at the rotational matching point of the flip push plate and the bracket, thereby forming a flip push plate structure, forming the structural condition for disconnecting the resistance conduction path, and this structure is the core innovation of the adjustable bar box pushing device. In order to ensure the function of pushing the bar box queue normally and avoid unnecessary flipping protection of the flip push plate, an overload protection structure is set at the position of the bracket close to the flip push plate. When the horizontal force applied by the bar box to the flip push plate is not greater than the preset force, the edge of the flip push plate is always blocked by the resistance bead to be in an upright state; at this time, if the bracket moves linearly toward the bar box, the flip push plate can push the bar box. When the horizontal force applied by the bar box to the flip push plate is greater than the preset force, the flip push plate swings upward after overcoming the resistance of the resistance bead; at this time, the resistance bead is exposed less from the structure of the mounting tube, and the elastic potential energy of the compression elastic member increases, thereby completing the overload protection. Therefore, the technical effect achieved by this design is: when the bar box is blocked at the terminal output position of the CV equipment, the flip push plate is blocked, and the flip push plate flips after overcoming the blocking force applied by the compression elastic member to the resistance bead, completing the overload protection. Therefore, the adjustable box pusher with overload protection structure of the utility model can solve the problem that the existing box pusher cannot unload force due to obstruction, protect the key parts of the equipment from damage, reduce the equipment accidents caused by this, and improve the production efficiency of the equipment.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0050] Aiming at the current drawbacks that the box push plate cannot unload the overload, such as Figure 2 , Figure 3 as well as Figure 4 As shown, the utility model provides an adjustable box pushing device with an overload protection structure, comprising:

[0051] A driving device (not shown);

[0052] The bracket 1 is transmission-connected to the driving device to perform horizontal linear motion;

[0053] A flip push plate 2 for pushing the strip box 4, wherein the upper and lower sides of the flip push plate 2 are respectively an upper side and a lower side, and the upper side is rotatably arranged on the bracket 1;

[0054] The overload protection structure 3 includes a mounting tube 31 arranged on the bracket 1, a resistance adjustment rod 32 extending into the mounting tube 31, a resistance bead 33 movably arranged in the mounting tube 31, and a compression elastic member 34 arranged in the mounting tube 31. The mounting tube 31 has a transversely penetrating tube cavity, and the tube cavity is reduced at one end close to the flip push plate 2. The resistance adjustment rod 32 extends into the mounting tube 31 through the tube cavity away from the flip push plate 2. The length of the resistance adjustment rod 32 extending into the tube cavity is adjustable. A part of the resistance bead 33 is exposed from the mounting tube 31 to abut against the edge of the flip push plate 2. The two ends of the compression elastic member 34 along its own compression direction abut against the resistance adjustment rod 32 and the resistance bead 33 respectively.

[0055] When the horizontal force applied by the box 4 to the flip push plate 2 is not greater than the preset force, the edge of the flip push plate 2 is always blocked by the resistance beads 33 to be in an upright state;

[0056] When the horizontal force applied by the barrel 4 to the flip push plate 2 is greater than the preset force, the flip push plate 2 swings upward after overcoming the resistance of the resistance beads 33 .

[0057] The adjustable box push device of the utility model changes the integrated box push plate in the prior art into a flip push plate 2 with adjustable resistance, which is used to solve the problem in the prior art that the transmission gear is damaged because the box pusher is blocked and cannot unload force. The height of the cantilevered side of the bracket 1 is higher than the height of the box 4 to be pushed, forming the basic spatial condition for the flip push plate 2 to disconnect the resistance conduction path. The upper side of the flip push plate 2 is rotatably arranged on the bracket 1, and a rotating shaft can be added at the rotational matching point of the flip push plate 2 and the bracket 1, thereby forming a flip push plate structure, forming the structural condition for disconnecting the resistance conduction path, and this structure is the core innovation of the adjustable box push device. In order to ensure the function of pushing the strip box queue normally and avoid unnecessary overturning protection of the flip push plate 2, an overload protection structure 3 is set at the part of the bracket close to the flip push plate 2. When the horizontal force applied by the strip box 4 to the flip push plate 2 is not greater than the preset force, the edge of the flip push plate 2 is always blocked by the resistance bead 33 to be in an upright state; at this time, if the bracket 1 moves linearly toward the strip box 4, the flip push plate 2 can push the strip box 4. When the horizontal force applied by the strip box 4 to the flip push plate 2 is greater than the preset force, the flip push plate 2 swings upward after overcoming the resistance of the resistance bead 33; at this time, the resistance bead 33 is exposed less in the mounting tube 31, and the elastic potential energy of the compression elastic member 34 is increased, thereby completing the overload protection. Therefore, the technical effect achieved by this design is: when the strip box is blocked at the output position of the CV equipment terminal (such as a CV strip box transparent paper packaging machine), the flip push plate 2 is blocked, and the flip push plate 2 flips after overcoming the blocking force applied by the compression elastic member 34 to the resistance bead 33, completing the overload protection.

[0058] Therefore, the adjustable box pusher with overload protection structure of the utility model can solve the problem that the existing box pusher cannot unload force due to obstruction, protect the key parts of the equipment from damage, reduce the equipment accidents caused by this, and improve the production efficiency of the equipment.

[0059] Furthermore, in order to perform an instant stop operation, the adjustable box pusher with an overload protection structure further includes a sensor and a sensed object, the sensor is arranged on the bracket 1 and is communicatively connected to the driving device, the sensed object is arranged on the flip push plate 2, and the sensor is moved away from the sensed object after the flip push plate 2 is flipped or the sensor is moved close to the sensed object after the flip push plate 2 is flipped. For example, see Figure 3 After the flipping push plate 2 is blocked and flipped over to complete the overload protection, the sensor (such as a metal proximity sensor) installed on the shoulder of the bracket triggers a fault signal because the flipping push plate 2 is flipped away from the sensed object. The sensor feeds back the fault signal to the drive device, and the drive device immediately executes a shutdown action to protect other components that may be damaged due to the blockage of the box.

[0060] In order to adjust the length of the resistance adjusting rod 32 extending into the lumen by the self-rotation of the resistance adjusting rod 32 , the overload protection structure 3 further includes a nut 35 , which is disposed on the bracket 1 and threadedly matched with the resistance adjusting rod 32 .

[0061] Furthermore, the compression elastic member 34 is a compression spring.

[0062] Furthermore, in order to rotate the resistance adjustment rod 32 by means of an inner hexagonal wrench, an inner polygonal hole is provided on the end of the resistance adjustment rod 32 extending from the mounting tube 31, and the inner polygonal hole is an inner hexagonal hole.

[0063] Furthermore, in order to simplify the structure of the bracket 1 , the bracket 1 includes a base 11 , a vertical plate 12 , a horizontal plate 13 and a suspension plate 14 which are connected in sequence, and the suspension plate 14 and the flip push plate 2 are hinged to each other.

[0064] Furthermore, in order to improve the rigidity of the bracket 1 , a first reinforcing rib 15 is provided between the base 11 and the vertical plate 12 ; and / or a second reinforcing rib 16 is provided between the vertical plate 12 and the horizontal plate 13 .

[0065] Furthermore, in order to facilitate the disassembly and assembly of the bracket 1, the suspension plate 14 is detachably connected to the cross plate 13 via a connecting assembly.

[0066] Furthermore, in order to simplify the structure of the suspension plate 14, the suspension plate 14 is a groove structure with an opening facing downward, and the suspension plate 14 includes a groove bottom 141, a first groove wall portion 142 and a second groove wall portion 143, and the spacing between the first groove wall portion 142 and the second groove wall portion 143 is adapted to the width of the flip push plate 2; the overload protection structure 3 is arranged in one of the first groove wall portion 142 and the second groove wall portion 143.

[0067] Furthermore, the resistance ball 33 is a steel ball.

[0068] In summary, the utility model has an adjustable box pusher with an overload protection structure, which can solve the problem that the existing box pusher cannot unload due to obstruction, protect the key parts of the equipment from damage, reduce the equipment accidents caused by them, and improve the production efficiency of the equipment. Therefore, the utility model effectively overcomes the various shortcomings of the existing technology and has a high industrial utilization value.
