Description

Technical Field

[0001] The utility model relates to a lifting device for an empty carton of a special-shaped cigarette product. Background Art

[0002] Compared with traditional cigarette products, special-shaped packaged cigarette products mostly use finished cigarette boxes, but the production process of finished cigarette boxes is relatively complicated, and some defective products are inevitable. When the empty carton is transported to the carton packaging device with the bottom facing up, the carton sometimes opens automatically due to the weak magnetic attraction of the carton. The automatically opened empty carton will jam the transmission part of the equipment when moving to the next workstation, seriously affecting production efficiency. Utility Model Content

[0003] In order to solve the above technical problems, the utility model proposes a lifting device for empty cartons of special-shaped cigarette products, which effectively avoids the phenomenon of equipment being stuck due to automatic opening of the cartons, thereby ensuring smooth production.

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

[0005] A lifting device for an empty carton of special-shaped cigarette products, the structural features of which are:

[0006] It includes a base, a lifting platform, a driving device, a synchronous belt transmission mechanism, a screw nut assembly, a base, a baffle assembly, a linear guide rail, an upper proximity switch, and a lower proximity switch;

[0007] The drive device is driven by the synchronous belt transmission mechanism to drive the screw rod coaxially connected with the driven pulley shaft to rotate forward or reversely. The lifting platform is fixed on the nut on the screw rod, and the two sides are respectively connected to the sliders of a pair of linear guide rails. Guided by the linear guide rails, it moves synchronously with the nut, or rises to the upper limit, or falls to the lower limit. When it reaches the upper limit, the upper proximity switch detects the in-position signal, and when it reaches the lower limit, the lower proximity switch detects the in-position signal; the baffle assembly includes a front baffle, a rear baffle and a side baffle The front baffle is fixed on the base and is independent of the lifting platform. When the lifting platform is at the lower limit position, it is surrounded at the front edge of the top of the lifting platform. When the lifting platform is at the upper limit position, it is below the lifting platform. The rear baffle is fixed on the rear edge of the top of the lifting platform, and the side baffle is fixed on the left edge. The right side is exposed as a strip box pushing inlet. The top of the lifting platform at the lower limit position is in an area surrounded by the front baffle, the rear baffle and the side baffles. A single empty strip box can be accommodated to be placed in the strip box pushing inlet, and a gap is left between the outer box wall of the empty strip box.

[0008] The structural features of the utility model also lie in:

[0009] The driving device is a servo motor, and the motor output shaft is coaxially connected with the driving pulley shaft of the synchronous belt transmission mechanism.

[0010] A pair of vertical plates with stiffening ribs are arranged on the base, and a group of linear guide rails are respectively arranged on opposite sides of the pair of vertical plates, and the pair of linear guide rails are symmetrically arranged left and right.

[0011] The synchronous belt transmission mechanism is arranged at the bottom of the base.

[0012] The lifting platform and the screw nut assembly are arranged between a pair of vertical plates.

[0013] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0014] The utility model utilizes a driving device to drive, which is transmitted through a synchronous belt transmission mechanism, and drives the lifting platform to rise or fall through a screw nut assembly. When it falls to the lower limit position, the lifting platform at the top end can receive the inverted empty strip box from the exposed right side in the area surrounded by the front baffle, the rear baffle and the side baffles, and rise to the upper limit position with the empty strip box. Since the front baffle is independent of the lifting platform, when the lifting platform rises, the front side will be exposed, and the empty strip box can be moved out from the front side to the next workstation under the action of external force. During the rising process, the enclosure of the rear baffle and the side baffles can effectively prevent the box cover of the empty strip box from opening automatically, thereby ensuring the smooth progress of production.

[0019] Please refer to Figure 1 to Figure 2The lifting device for the empty carton of special-shaped cigarette products of this embodiment includes a base 11, a lifting platform 2, a driving device 3, a synchronous belt transmission mechanism, a screw nut assembly, a base 11, a baffle assembly, a linear guide 4, an upper proximity switch 81, and a lower proximity switch 82;

[0020] Driven by the driving device 3 and the synchronous belt transmission mechanism, the screw rod 61 coaxially connected to the axle of the driven pulley 51 is driven to rotate forward or reversely. The lifting platform 2 is fixed on the nut 62 on the screw rod 61, and the two sides are respectively connected to the sliders of a pair of linear guide rails 4. Guided by the linear guide rails 4, it moves synchronously with the nut 62, or rises to the upper limit position, or falls to the lower limit position. When it reaches the upper limit position, the upper proximity switch 81 detects the position signal, and when it reaches the lower limit position, the lower proximity switch 82 detects the position signal; the baffle assembly includes a front baffle 71, a rear baffle 72 and a side baffle 73. The front baffle 71 is fixed It is arranged on the base 11 and is independent of the lifting platform 2. When the lifting platform 2 is at the lower limit position, the enclosure is at the front edge of the top of the lifting platform 2. When the lifting platform 2 is at the upper limit position, it is below the lifting platform 2, so that the front side of the lifting platform 2 is completely exposed and not blocked. A rear baffle 72 is fixed on the rear edge of the top of the lifting platform 2, and a side baffle 73 is fixed on the left edge. The right side is exposed as a strip box pushing inlet. The top of the lifting platform 2 at the lower limit position is in an area enclosed by the front baffle 71, the rear baffle 72 and the side baffle 73, which can accommodate a single empty strip box from the strip box pushing inlet, leaving a gap between the outer box wall of the empty strip box.

[0021] In a specific implementation, the corresponding structural setting of the device also includes:

[0022] The device is connected between the upstream and downstream stations of the strip box packaging device, and only serves as a transfer platform for empty strip boxes between the upstream and downstream stations. The mechanisms used for the input / output of empty strip boxes are all existing parts of the strip box packaging device. The lifting platform at the lower limit position faces the strip box push-in port and receives the empty strip box pushed in from the previous station, and the lifting platform at the upper limit position faces the front side and cooperates with the next station to complete the removal of the empty strip box.

[0023] The driving device 3 is a servo motor, and the motor output shaft is coaxially connected to the axle of the driving pulley 52 of the synchronous belt transmission mechanism. The synchronous belt and the servo motor are not shown in the figure.

[0024] A pair of vertical plates 13 with stiffening ribs 12 are disposed on the base 11 , and a group of linear guide rails 4 are respectively disposed on opposite sides of the pair of vertical plates 13 , and the pair of linear guide rails 4 are symmetrically arranged left and right.

[0025] The synchronous belt transmission mechanism is arranged at the bottom of the base 11 .

[0026] The lifting platform 2 and the screw rod 61 and nut 62 assembly are arranged between a pair of vertical plates 13 .

[0027] This device can be used to complete the reliable transfer of empty strip boxes with the bottom facing upward between upstream and downstream stations, so that the empty strip boxes can arrive at the next station smoothly, avoiding the situation where the box cover is automatically opened during the transfer process due to the loose magnetic attraction. The lifting platform is initially at the lower limit position, and the inverted empty strip box is pushed horizontally from the strip box push entrance to the top of the lifting platform in the area surrounded by the front baffle, the rear baffle and the side baffle, with the opening side of the box cover facing the rear baffle. After that, the drive device drives, the synchronous belt transmission mechanism drives, the screw rod rotates, and the lifting platform is guided by a pair of linear guides and rises with the nut until it reaches the upper limit position. At this time, the front baffle is lower than the lifting platform, so that the front side of the lifting platform is completely exposed. At this time, the empty strip box on the lifting platform can be ready to move forward to the next station. After the empty strip box is completely moved out, the lifting platform drops to the lower limit position, and the cycle continues.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
