Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging machines, in particular to a cigarette pack blocking block structure applied to a 741 pack storage device. Background Art

[0002] Both FX and ZB48A packaging machines are equipped with 741 pack storage devices. When the downstream equipment equipped with the 741 pack storage device is shut down, the 741 pack storage device will store the cigarette packs. The cigarette pack block will block the cigarette groups during transportation. After 18 packs of cigarette packs are formed, the cigarette push rod will push the cigarettes into the 741 pack storage device for buffering to ensure the continuous operation of the upstream equipment.

[0003] During the storage process, the cigarette pack block 4 needs to be moved to block the cigarette pack, such as Figure 1 As shown, the stopper 4 is driven by the cylinder 1 through the connecting rod mechanism to drive the spherical bearing 2 to move, and then the spherical bearing 2 drives the transmission shaft 3 to rotate, thereby driving the stopper 4 installed on the upper part of the transmission shaft 3 to rotate, thereby realizing the cigarette bag blocking function.

[0004] However, in actual operation, the block 4 often moves slowly, causing the product cigarette packs to be pinched, which will cause: (1) defective cigarette packs to flow into the next process, posing a great quality risk; (2) frequent cigarette pinching will cause the block movement to require frequent adjustment; (3) cigarette pinching will cause a large load on the cylinder connecting rod, making the cylinder, connecting rod and spherical bearing 2 easy to be damaged, difficult to replace and time-consuming. Utility Model Content

[0005] In view of the above problems, the utility model provides a cigarette pack block structure applied to the 741 pack storage device, which effectively avoids the problem of defective cigarette packs being clamped and flowing into the next process, while reducing the load on the cylinder connecting rod and improving the service life.

[0006] Specifically, the utility model provides a cigarette pack block structure applied to a 741 pack storage device, comprising:

[0007] Clamping block;

[0008] a baffle, disposed on the clamping block and configured to slide along the length direction of the clamping block;

[0009] The elastic member is arranged on the clamping block and connected to the baffle. When the cigarette pack presses the baffle to move the baffle along the length direction of the clamping block, the elastic member is compressed.

[0010] Furthermore, a sliding groove is provided on the side of the clamping block, and the baffle is slidably connected in the sliding groove.

[0011] Further, the baffle is provided with a waist-shaped hole, the clamping block is provided with a first connecting pin, the first connecting pin is located in the waist-shaped hole, the end of the baffle away from the cigarette pack is provided with a second connecting pin, and the first connecting pin and the second connecting pin are connected by the elastic member.

[0012] Further, the elastic member is a tension spring.

[0013] Further, the first connecting pin is threadedly connected to the clamping block.

[0014] Further, a detection device is provided at the end of the clamping block away from the cigarette pack, and the detection device is used to detect the presence or absence of the baffle.

[0015] Further, the clamping block is mounted on the transmission shaft by two screws.

[0016] Working principle:

[0017] When it is necessary to block the cigarette pack, the cylinder drives the two blocking blocks to rotate to block the downstream transportation of the cigarette pack. When the blocking block moves slowly and causes the cigarette pack to be clamped, the cigarette pack pushes the baffle backward, and at the same time compresses the tension spring, playing a buffering role, which will neither pinch the cigarette pack nor reduce the load borne by the cylinder and the connecting rod mechanism. When the baffle moves backward, the detection device on the clamping block detects the baffle and sends a signal to the device, and the device reports a fault and stops.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] (1) The cigarette pack blocking block structure provided by the present utility model can effectively avoid pinching the cigarette pack and ensure product quality.

[0020] (2) Through the buffering effect of the tension spring, the load borne by the cylinder connecting rod mechanism can be effectively reduced, the service life can be improved, and at the same time the position of the clamping block is stable and reliable.

[0021] (3) By detecting the position of the baffle, the situation of pinching the cigarette pack can be timely monitored, the correctness of the cigarette pack position can be ensured, and the normal progress of the next process can be ensured. Description of the drawings

Detailed implementation manners

[0029] The present utility model will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0030] Embodiment 1

[0031] As Figure 2 shown, this embodiment provides a cigarette packet stopper structure applied to a 741 cigarette packet storage device. Two cigarette packet stopper structures are respectively located on both sides of the cigarette feeding channel, jointly blocking the cigarette packet 9, so as to realize the cigarette packet storage function.

[0032] As Figure 3-4 shown, each cigarette packet stopper structure includes: a clamping block 5, a baffle 6, an elastic member and a photoelectric sensor 8. The clamping block 5 is integrally in a structure similar to a clamp, and is fixed on the transmission shaft 3 of the 741 cigarette packet storage device by two screws 52. A slide groove 51 is provided on the side of the clamping block 5, and a first connecting pin 71 is installed on the side wall of one side of the slide groove 51 through a screw hole. The baffle 6 is slidably arranged in the slide groove 51, and a kidney-shaped hole 61 is provided thereon. The first connecting pin 71 passes through the kidney-shaped hole 61, and the kidney-shaped hole 61 is offset from the first connecting pin 71 to avoid the first connecting pin 71 blocking the baffle 6. A second connecting pin 72 is fixed at the end of the baffle 6 (i.e., the end far from the cigarette packet 9), and the second connecting pin 72 is connected to the first connecting pin 71 by a tension spring 73.

[0033] As Figure 5 shown, when the baffle 6 is squeezed and moves backward, the tension spring 73 is compressed, and a buffer structure is formed through the tension spring 73, which can not only effectively avoid pinching the cigarette packet 9, but also effectively reduce the load borne by the cylinder 1 and the link mechanism, improve the service life of the cylinder, the link mechanism and the spherical plain bearing. At the same time, it can effectively avoid the problem that the clamping block 5 needs to be frequently adjusted due to the displacement caused by frequent cigarette clamping.

[0034] Furthermore, a photoelectric sensor 8 is provided at the end of the clamping block 5 far from the cigarette packet 9. The photoelectric sensor 8 is connected to the equipment control system. When the baffle 6 moves backward, its end extends backward and is detected by the photoelectric sensor 8. At this time, the photoelectric sensor 8 will transmit a signal to the equipment control system, and the equipment will report a fault and stop, thus preventing the misaligned cigarette packet after being clamped from flowing into the next process.

[0035] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model pertains, based on the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
