For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Combination Figure 1 , 2As shown, the needle guide device of the present invention includes a needle threading device base plate 7, a needle cloth base plate 3, a U-shaped needle cloth groove block 1, a guide block 2, a limit block 12, a push plate 4 and a driving device.

[0029] A cloth needle base plate 3 is arranged above the needle threading device base plate 7, and a U-shaped cloth needle slot block 1 is arranged above the cloth needle base plate 3. A gap is arranged between the cloth needle base plate 3 and the U-shaped cloth needle slot block 1 for the push plate 4 to move. A driving device is connected to one side of the push plate 4 to drive the push plate 4 forward and backward.

[0030] In order to ensure the moving direction of the U-shaped needle when the push plate 4 pushes the U-shaped needle to move, a guide block 2 is arranged below the U-shaped needle slot block 1, and a guide groove 11 is arranged on the guide block 2.

[0031] A limit block 12 is also provided on the bottom plate 7 of the needle threading device. There is a gap between the limit block 12 and the U-shaped needle slot block 1 for the cigarette clamp to move. The push plate 4, the guide block 2 and the limit block 12 are arranged in sequence in the horizontal direction along the travel direction of the U-shaped needle.

[0032] A U-shaped needle slot is provided in the U-shaped needle slot block 1 for placing U-shaped needles. The U-shaped needle slot in the U-shaped needle slot block 1 has a certain depth, and the U-shaped needles are stacked in the U-shaped needle slot. Since multiple U-shaped needles are required on the cigarette clamp tube, multiple U-shaped needle slots are arranged in parallel in the horizontal direction in the U-shaped needle slot block 1, so that multiple U-shaped needles can be inserted at one time.

[0033] The width of the push plate 4 is adapted to the total width of the multiple U-shaped needle distribution grooves arranged in parallel in the horizontal direction in the U-shaped needle distribution groove block 1, so that the push plate can push multiple U-shaped needles of a layer at one time, thereby realizing one-time threading of multiple U-shaped needles on the cigarette clamp tube.

[0034] The guide groove 11 on the guide block 2 axially penetrates the guide block, the top of the guide groove 11 is open, and the axial direction of the guide groove 11 is parallel to the moving direction of the push plate 4. The two arms of the U-shaped needle pass through the guide groove 11 to control the travel posture of the U-shaped needle.

[0035] The guide block 2 can move up and down. In this embodiment, the bottom plate 7 of the needle threading device is provided with a hole for the guide block 2 to move up and down. In order to realize the up and down movement of the guide block 2, a cam is installed at the bottom of the guide block 2 to drive the guide block. The cam abuts against the guide block 2, and when the cam rotates, it can drive the guide block 2 to move up or down.

[0036] After the push plate 4 pushes the U-shaped needle forward and the front ends of the two arms of the U-shaped needle penetrate into the hole of the cigarette clamp tube, the guide block 2 can move downward. Since the top of the guide groove 11 is open, the guide block 2 is separated from the U-shaped needle, thereby avoiding the guide block 2 from hindering the movement of the U-shaped needle, so that the push plate 4 can push the U-shaped needle to continue to pass through the cigarette clamp tube.

[0037] When the push plate 4 pushes the U-shaped needle into position, the driving device drives the push plate 4 to retreat to a certain position, and the cam pushes against the guide block 2 to move upward, so that the guide groove 11 can continue to limit the subsequent U-shaped needles.

[0038] In order to allow the U-shaped needle to enter the guide groove 11 better, the guide groove 11 of the guide block 2 is trumpet-shaped or Y-shaped, and its open side is adjacent to the push plate.

[0039] The number of guide grooves 11 matches the number of U-shaped needle slots. Since the U-shaped needle has two arms, one U-shaped needle corresponds to two guide grooves 11, that is, one U-shaped needle slot corresponds to two guide grooves 11.

[0040] In this embodiment, the driving device includes a push plate fixing frame 5 , a push rod fixing frame 6 and a push rod 10 . One side of the push plate 4 is connected to the push plate fixing frame 5 . The push plate fixing frame 5 is connected to the push rod fixing frame 6 . The push rod fixing frame 6 is connected to the push rod 10 .

[0041] In this embodiment, the push rod 10 is powered by an electric push rod.

[0042] A horizontal hole is provided on the stop block 12, the axial direction of the hole is consistent with the travel direction of the push plate 4, and the height of the hole is adapted to the height of the clearance provided between the needle base plate 3 and the U-shaped needle slot block 1 for the push plate 4 to move. One radial side of the hole is open, and the U-shaped needle after the cigarette clamp tube is threaded withdraws from the stop block 12.

[0043] When working, the U-shaped needles at the bottom layer in the U-shaped needle cloth groove fall into the gap between the needle cloth bottom plate 3 and the U-shaped needle cloth groove block 1, and the push plate 4 pushes this layer of U-shaped needles to move toward the cigarette clamp tube. The two arms of the U-shaped needle are inserted into the guide groove 11 of the guide block. The travel direction of the U-shaped needle is controlled by the guide groove 11. After the front ends of the two arms of the U-shaped needle penetrate into the hole of the cigarette clamp tube, the guide block 2 moves downward. Since the top of the guide groove 11 is open, the guide block 2 is separated from the U-shaped needle. The push plate 4 continues to push the U-shaped needle. The front ends of the two arms of the U-shaped needle penetrate the cigarette clamp tube and then penetrate into the limit block 12. After the push plate 4 continues to push the U-shaped needle forward to the right position, the electric push rod retreats and drives the push plate 4 backward. Since the push plate 4 is in the gap between the cloth needle bottom plate 3 and the U-shaped cloth needle groove block 1, the U-shaped needle in the U-shaped cloth needle groove cannot fall into this gap. After the push plate 4 retreats to the right position, the U-shaped needle at the bottom of the U-shaped cloth needle groove falls into this gap, and the cam rotates to abut against the guide block 2 to rise, so that the height of the guide groove 11 matches the height of the aforementioned gap, thereby waiting for the push plate 4 to move forward and wait for the next push plate 4 to push the U-shaped needle to thread other cigarette clamp tubes. The cigarette clamp tubes that have been threaded can be taken away.

[0044] In order to facilitate the production of the U-shaped needle groove block 1, multiple layers of U-shaped needle groove plates are stacked, each layer of which has a U-shaped needle groove that passes through from top to bottom, thus forming a U-shaped needle groove block with a certain depth inside.

[0045] The needle insertion guide device of the present invention stacks multiple layers of U-shaped needles through a U-shaped needle distribution groove with a certain depth in a U-shaped needle distribution groove block, and pushes the bottom layer of U-shaped needles to the cigarette clamp tube through a push plate to achieve needle threading. In order to achieve direction control during the advancement of the U-shaped needle, a guide block is provided, and a guide groove is provided on the guide block. The two arms of the U-shaped needle travel in the guide groove, so that the U-shaped needle can be fixed in direction during the process of being pushed by the push plate to achieve accurate needle threading. The U-shaped needles fall layer by layer and are pushed to the cigarette clamp tube by the push plate to achieve needle threading. The structure is simple, and can achieve rapid, accurate and continuous needle distribution, guidance, and needle threading, reduce manpower, reduce labor intensity, and greatly improve production efficiency.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
