Abstract
Description
Technical Field
[0001] The utility model relates to a mechanism for pulling a mold core rod on paper tube manufacturing equipment. Background Art
[0002] The paper tube manufacturing equipment is a kind of paper tube manufacturing equipment that uses paper tape as a production material, and the paper tape is spirally wound around a mold core rod to form a paper tube. The paper tube manufacturing equipment is provided with a cutter for cutting the paper tube. The cutter and the mold core rod move with the continuous production of paper tubes. After the paper tube is produced to the required length, the cutter cuts the paper tube, and the cutter and the mold core rod return to the initial position. In the prior art, the pull rod of the paper tube manufacturing equipment pulls back the mold core rod, and the power of the pull rod comes from the power of the cutter resetting, so a transmission rod is required, one end of the transmission rod is connected to the cutter, and the other end is connected to the farthest end of the pull rod. The problem with this structure is that when the cutting length of the paper tube is very long, the length of the transmission rod must be longer. After the length of the transmission rod is extended, the manufacturing cost is high, and the operation stability is weak. Utility Model Content
[0003] The technical problem to be solved by the utility model is to solve the deficiencies in the prior art and provide a mechanism for pulling a mold core rod on paper tube manufacturing equipment that can operate independently.
[0004] The technical solution adopted by the utility model is: a mechanism for pulling a mold core rod on a paper tube manufacturing device, including two rotatably arranged belt pulleys, a motor for driving the belt pulleys to rotate, and a transmission belt stretched on the two belt pulleys. The transmission belt is fixedly connected to a pull rod through a connecting piece, and the pull rod moves with the movement of the transmission belt. The connecting piece touches a proximity switch during the interaction process.
[0005] It also includes a slide rail and a slider slidably connected to the slide rail, and the slider is fixedly connected to the connecting piece; the slide rail is fixedly connected to the frame of the paper tube manufacturing equipment.
[0006] Wherein, the connecting member includes a first seat body and a second seat body, the first seat body has a groove for the transmission belt to fall into, and the second seat body has an insertion portion that can fall into the groove and a recessed position for the pull rod to fall into.
[0007] Compared with the prior art, the beneficial effect of the present invention is that the mechanism for pulling the mold core rod on the paper tube manufacturing equipment in the present invention adopts a transmission belt drive as the traction power. After the arrangement of this mechanism, the very long transmission rod is eliminated compared with the prior art, and the overall operation is more stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0009] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments.
[0010] like Figure 1 As shown, the mechanism for pulling the mold core rod on the paper tube manufacturing equipment in this embodiment includes two rotatably arranged belt pulleys 4, a motor 1 driving the belt pulleys 4 to rotate, and a transmission belt 3 stretched on the two belt pulleys 4. The transmission belt 3 is fixedly connected to a pull rod 5 through a connecting member 2. The pull rod 5 moves with the movement of the transmission belt 3, and the connecting member 2 touches the proximity switch 6 during the interaction. In this embodiment, the two belt pulleys 4 are rotatably connected to the frame, the motor 1 is fixedly connected to the frame, the pull rod 5 is fixedly connected to the mold core rod, the rotor of the motor 1 is fixedly connected to the belt pulley 4, the belt pulley 4 rotates to drive the transmission belt 3 to move, the pull rod 5 is fixedly connected to the transmission belt 3 through the connecting member 2, and the connecting member 2 touches the proximity switch 6 during the movement, and the original operating device of the motor 1 is changed after touching the proximity switch 6.
[0011] As a preferred embodiment, it also includes a slide rail 7 and a slider slidably connected to the slide rail 7, the slider is fixedly connected to the connecting member 2; the slide rail 7 is fixedly connected to the frame of the paper tube manufacturing equipment. The frame of the paper tube manufacturing equipment remains fixed to the ground, and after the slide rail 7 and the slider are set, the linear movement of the connecting member 2 is more stable and reliable.
[0012] As a preferred embodiment, the connecting member 2 includes a first seat body 21 and a second seat body 22, wherein the first seat body 21 has a groove 210 for the transmission belt 3 to fall into, and the second seat body 22 has an insertion portion that can fall into the groove 210 and a recessed position 220 for the pull rod 5 to fall into.
