Description

Technical Field

[0001] The utility model relates to a cigarette box clamping device, belonging to the technical field of cigarette packaging. Background Art

[0002] Cigarette packing is an important process for packing cigarettes. Before the cigarette packing device puts cigarettes into empty boxes, it needs to fix the empty cigarette boxes conveyed by the conveyor belt from the previous station. The internal space of the cigarette packing device is usually narrow, and it is difficult to set up an effective cigarette box clamping device. Therefore, the existing technology mostly adopts a fixed structure cigarette clamping method, that is, a cigarette clamping cavity for clamping the cigarette box is provided inside the cigarette clamping mechanism, and the opening size of the cigarette clamping cavity is smaller than the size of the cigarette box (usually about 1mm), so as to clamp the cigarette box.

[0003] However, because the opening size of the cigarette clamping cavity is smaller than that of the cigarette box, when the empty cigarette box is pushed into the cigarette clamping cavity, friction will form between the outer surface of the cigarette box and the side wall of the cigarette clamping cavity, which may cause a certain degree of damage to the outer surface of the cigarette box, thereby reducing the packaging quality of the product after the cigarettes are put into the box. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a cigarette box clamping device which has a compact structure and can effectively avoid damaging the outer surface of the cigarette box.

In this way, the clip plate arranged on the vertical slider is driven by the push-up assembly, so that the cigarette clamping cavity in the cigarette clamping assembly has two states, one open and one closed.

[0006] On the other hand, the utility model also proposes another cigarette box clamping device, including a frame, a pushing assembly and a cigarette clamping assembly, the pushing assembly and the cigarette clamping assembly are arranged on the frame; the cigarette clamping assembly includes a sliding seat, a first vertical slider and a second vertical slider arranged on the frame, the first vertical slider and the second vertical slider respectively form a moving pair with the sliding seat, the first vertical slider is fixedly connected to a first clamp, the second vertical slider is fixedly connected to a second clamp, the first clamp and the second clamp are respectively located on the upper and lower sides of the sliding seat, the first clamp and the second clamp form a cigarette clamping cavity; the pushing assembly is used to make the first vertical slider and the second vertical slider reciprocate up and down along the sliding seat respectively, so that the cigarette clamping cavity in the cigarette clamping assembly has two states, one open and one closed.

[0007] The utility model drives the cigarette clamping cavity in the cigarette clamping assembly to open and close through the push-up assembly, thereby clamping the empty cigarette box conveyed by the conveyor belt from the previous station, which is convenient for the subsequent cigarette box loading work. The utility model has a compact structure, and clamps the cigarette box by adjusting the opening size of the cigarette clamping cavity, which not only meets the requirement of reducing space occupation, but also can control the automatic opening and closing of the cigarette clamping cavity through the slider mechanism in the cigarette clamping assembly to ensure that the empty cigarette box is intact, and greatly avoids the occurrence of scratches and deformation on the surface of the cigarette box.

DETAILED DESCRIPTION

[0014] Embodiment 1

[0015] The cigarette box clamping device of this embodiment is as follows: Figure 1-Figure 4As shown, it includes a frame, a pushing assembly and a cigarette clamping assembly, and the pushing assembly and the cigarette clamping assembly are arranged on the frame.

[0016] The cigarette clamping assembly includes a slide 601 arranged on a frame, a vertical slider 602 forming a moving pair with the slide 601, and a clip 603 fixed on the vertical slider 602, wherein the clip 603 is located above the slide 601, and a horizontal smoke baffle 604 located below the clip 603 is provided on the side of the slide 601 away from the slider, and the clip 603 and the horizontal smoke baffle 604 form a cigarette clamping cavity 615.

[0017] The lifting assembly is used to make the vertical slider 602 reciprocate up and down along the slide 601. Figure 2 As shown, the push-up assembly in this embodiment includes a horizontal slider 605 moving along a slide 601, a driving mechanism 600 driving the horizontal slider 605, a cam 607 arranged on the horizontal slider 605, and a push rod 608 arranged on the vertical slider 602 and matching the cam 607. When the horizontal slider 605 moves along the slide 601, the vertical slider 602 slides up and down along the slide 601, so that the cigarette clamping cavity 615 in the cigarette clamping assembly has two states, one open and one closed. The slide 601 is provided with a spring 609 for resetting the vertical slider 602. The driving mechanism 600 can adopt existing technologies such as cylinders, which will not be described in detail.

[0018] In this embodiment, the horizontal movement of the horizontal slider 605 is converted into the vertical movement of the clamping piece 603 by setting the cooperation of the cam 607 and the push rod 608, so as to cleverly realize the action of clamping the cigarette box 100. Not only is the structure compact, but the cigarette box 100 can be clamped by adjusting the opening size of the cigarette clamping cavity 615, which can meet the requirement of reducing space occupation.

[0019] In order to facilitate the movement of the horizontal slider 605, a slide groove matching the horizontal slider 605 can be set on the slide 601. Preferably, the horizontal slider 605 in this embodiment is rod-shaped, and at least two pairs of guide rollers 611 are provided on the slide 601 in the horizontal direction. Each pair of guide rollers 611 are arranged upper and lower and clamp the horizontal slider 605, so that the structure is simpler.

[0020] When the cigarette box 100 needs to enter the cigarette clamping cavity 615, the driving mechanism 600 drives the horizontal slider 605 to move forward along the guide roller 611, thereby driving the vertical slider 602 to rise along the guide rail direction of the slide seat 601. At the same time, the spring 609 connecting the vertical slider 602 and the slide seat 601 is pulled up, so that the cigarette clamping cavity 615 has an opening size larger than the width of the cigarette box 100. When the cigarette box 100 completely enters the cigarette clamping cavity 615 and needs to be clamped, the driving mechanism 600 retracts. Under the action of the tension of the spring 609, the vertical slider 602 descends along the slide seat 601, so that the cigarette clamping cavity 615 has a size smaller than the width of the cigarette box 100. However, since the spring 609 is in an adaptive state, it can be ensured that the cigarette box 100 can be clamped without damaging the cigarette box 100.

[0021] like Figure 2 and Figure 3 As shown, this embodiment can also be improved as follows:

[0022] 1) A vertical smoke baffle 610 is provided between the clamping piece 603 and the horizontal smoke baffle 604, and the vertical smoke baffle 610 is located at the rear end of the cigarette clamping cavity 615. This can limit the position of the cigarette box 100 to be clamped, facilitating the subsequent operation of inserting cigarettes into the box.

[0023] 2) The horizontal slider 605 is provided with a limit groove 612 extending in the horizontal direction, and the slide seat 601 does not have a limit pin 613 inserted into the limit groove 612. Through the cooperation of the limit groove 612 and the limit pin 613, the moving distance of the horizontal slider 605 can be limited to prevent the stroke from being too large, thereby limiting the lifting distance of the clamping piece 603 and improving the efficiency of clamping cigarettes.

[0024] 3) In order to facilitate the cigarette box 100 to enter the cigarette clamping cavity 615 , a guide expansion opening 614 is provided at the opening of the cigarette clamping cavity 615 .

[0025] Embodiment 2

[0026] This embodiment is an improvement on the first embodiment, and is different from the first embodiment in that the structure of the push-up assembly is different. The push-up assembly in this embodiment includes a cylinder mounted on a frame, and the piston rod of the cylinder drives the vertical slider 602 to move along the slide 601. This embodiment can have multiple implementations, such as: 1) the piston rod of the cylinder is fixedly connected to the vertical slider 602, and the cylinder body of the cylinder is fixedly connected to the frame, and the vertical slider 602 is driven to move the clamp 603 by the extension and contraction of the cylinder piston rod; 2) the cylinder is a rotary cylinder, and the piston rod of the cylinder drives the lever to drive the vertical slider 602 to move.

[0027] Of course, the pushing component may also adopt other existing technologies as long as it can drive the vertical slider 602 to move up and down along the slide seat 601.

[0028] Embodiment 3

[0029] The difference between this embodiment and the first and second embodiments is that: in this embodiment, the horizontal smoke baffle 604 of the cigarette clamping assembly is replaced by another clip 603, that is, the cigarette clamping assembly includes a slide 601, a first vertical slider 602 and a second vertical slider 602 arranged on the frame, the first vertical slider 602 and the second vertical slider 602 respectively form a moving pair with the slide 601, the first vertical slider 602 is fixedly connected to the first clip 603, the second vertical slider 602 is fixedly connected to the second clip 603, the first clip 603 and the second clip 603 are respectively located on the upper and lower sides of the slide 601, and the first clip 603 and the second clip 603 form a cigarette clamping cavity 615.

[0030] The pushing assembly described in this embodiment is used to make the first vertical slider 602 and the second vertical slider 602 reciprocate up and down along the slide 601 respectively. The pushing assembly is divided into two groups, which drive the first vertical slider 602 and the second vertical slider 602 respectively, and the structure of each group of pushing assemblies is the same as that in Example 1 and Example 2.
