Description

Technical Field

[0001] This utility model belongs to the field of plastic pipe cutting technology, specifically, it relates to a plastic pipe cutting device. Background Technology

[0002] Currently, to save costs, plastic pipe manufacturers typically purchase pipes of a certain length as needed during manufacturing. After delivery, these pipes are then manually cut to the required lengths. This manual, quantitative cutting process is prone to errors and is extremely inefficient, often requiring several workers to operate continuously. Furthermore, additional quality control procedures are needed to ensure the correct lengths, further increasing costs. Moreover, during the cutting process, inconsistent force and incorrect angles applied by workers can easily cause the plastic pipes to crack at the opening, severely impacting the finished product's pass rate.

[0003] Therefore, there is a need for a multi-station, automated quantitative cutting device for plastic pipe fittings to improve processing efficiency. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a plastic tube cutting device, which guides a single plastic tube through a guide ring and conveys it from the first inlet sleeve to the second inlet sleeve for orderly feeding. The bottom stop block is raised and lowered to adjust the height, and then the cutting component between the two sleeves automatically cuts, avoiding the trouble of manual cutting required in the past.

[0006] According to one embodiment of the present invention, the aforementioned stop block is equipped with a photoelectric counter, and the photoelectric counter feeds back a signal to the shearing assembly to shear the plastic tube.

[0007] According to one embodiment of the present invention, the shearing assembly includes a blade holder; a blade that slides along the blade holder; a cylinder that drives the blade; and a positioning plate fixed to the blade holder and located above the blade. The positioning plate has an opening through a plastic tube, and the area of ​​the opening is larger than the area of ​​the channel of the first inlet sleeve.

Detailed Implementation

[0019] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0020] Please refer to Figure 1 , Figure 1 This is a perspective view of a plastic pipe cutting device according to an embodiment of the present invention. As shown in the figure, a plastic pipe cutting device includes a frame 10, wherein a first horizontal bar 11, a second horizontal bar 12, a third horizontal bar 13, and a fourth horizontal bar 14 are arranged sequentially from top to bottom on the frame 10; a plurality of guide rings 20 are disposed on the first horizontal bar 11, and the guide rings 20 respectively guide a single plastic pipe; a first pipe inlet sleeve 31 is disposed on the second horizontal bar 12 and corresponds to the guide rings 20; a second pipe inlet sleeve 32 is installed on the lower side of the third horizontal bar 13 and guides the fourth horizontal bar 14; and the fourth horizontal bar 13 is arranged on the second horizontal bar 12 and corresponds to the guide rings 20. The second inlet sleeve 32 corresponds to the first inlet sleeve 31; a stop block 40 is set on the fourth horizontal bar 14 via a screw seat and corresponds to the second inlet sleeve 32. The stop block 40 has a clamp 41 through which the plastic tube passes and a receiving bucket is placed on its lower side. An electric push plate is set at the lower end of the clamp 41 for opening and closing the clamp 41; and a shearing assembly 50 is set on the upper side of the third horizontal bar 13 and located between the first inlet sleeve 31 and the second inlet sleeve 32. The shearing assembly 50 shears the plastic tube that passes through.

[0021] In one embodiment of this utility model, the frame 10 can be arranged vertically or at an angle, supported by a bracket and adjusted according to the workshop height. The plastic tube is guided to the guide ring 20 and conveyed individually through the guide ring 20 for orderly unloading. The plastic tube conveyed by the first inlet sleeve 31 is supported by the bottom stop block 40, whose height can be adjusted by the screw seat to adapt to the distance with the shearing component 50, thereby ensuring the shearing length. After being sheared by the shearing component 50, the plastic tube is guided and conveyed by the second inlet sleeve 32, and finally falls into the bottom collection bin for collection. The process is automatic, efficient, and convenient. Moreover, the shearing component 50 performs quantitative shearing, greatly improving accuracy. An electric push plate is provided at the lower end of the clamp 41 of the stop block 40 for opening and closing the clamp 41. That is, after the shearing component 50 completes the shearing, the electric push plate retracts, opening the clamp 41 and automatically unloading the material. The pre-shear stop completes the positioning, which is convenient and practical.

[0022] In addition, the stop block 40 is equipped with a photoelectric counter, which provides feedback signals to count and ensure that no cuts are missed.

[0023] Please refer to this as well. Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the shearing component according to an embodiment of the present invention; Figure 3This is a schematic diagram of the cutting tool according to an embodiment of the present invention. As shown, the shearing assembly 50 includes a blade holder 51; a cutting tool 52 that slides along the blade holder 51; a cylinder 53 that drives the cutting tool 52; and a positioning plate 54 fixed to the blade holder 51 and located above the cutting tool 52. The positioning plate 54 has an opening 55 for a plastic tube, and the area of ​​the opening 55 is larger than the area of ​​the channel of the first inlet sleeve 31. In this embodiment, the cylinder 53 drives the cutting tool 52 forward, pushing the plastic tube to the front edge of the opening 55 of the positioning plate 54. The two work together to achieve cutting, resulting in a simple structure and convenient operation. In addition, in other embodiments, the cutting tool of the present invention can be a self-heating cutting tool, suitable for some softer plastic tubes.

[0024] It is worth mentioning that the blade 52 of this utility model has a V-shaped cutting edge 56 with an angle. During the cutting process, the plastic tube can be gathered to the center of the V-shaped cutting edge 56, and the angle setting makes the cutting edge gradually thinner and sharper, and finally cuts off both sides, which is efficient and stable.

[0025] In addition, the lower opening of the second inlet sleeve 32 of this utility model tapers inward to create a smaller lower opening, which guides the fall to be stable.

[0026] In summary, this utility model guides a single plastic tube through a guide ring, which then transports it from the first inlet sleeve to the second inlet sleeve for orderly feeding. The bottom stop block is raised and lowered to adjust the height, and then the shearing component between the two sleeves automatically cuts the tube, avoiding the inconvenience of manual cutting required in the past.

[0027] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
