Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a high-speed pipe cutting machine. Background Art

[0002] In the food packaging industry, it is often necessary to paste tableware, such as straws, on the outer side of products containing food for consumers to use. At present, after the straws are produced, they are usually in the form of a packaged straw belt, in which multiple compartments containing straws are connected in a belt shape (and there is a tear line between adjacent compartments). When the straws leave the factory, sometimes each compartment needs to be cut off, but currently, it is mainly done manually, which is inefficient.

[0003] In order to solve the problems of low efficiency and high labor intensity caused by manually tearing the straws in the prior art, pipe cutting machines have emerged in the prior art. However, the existing pipe cutting machines on the market cut and place one by one, that is, cut one straw and place one straw, with low efficiency. Summary of the Utility Model

[0004] Therefore, in order to solve the above deficiencies, the utility model provides a high-speed pipe cutting machine here, which includes a pipe cutting component and a pipe feeding conveyor. The pipe cutting component continuously feeds a single straw cut by the pipe cutting component into the pipe feeding conveyor, so that the pipe feeding conveyor sends multiple straws to the outlet end of the pipe feeding conveyor;

[0005] The pipe cutting component includes

[0006] A power device;

[0007] A first pipe winding structure, which includes a large pipe winding roller. The large pipe winding roller is driven by the power device to rotate along its own circumferential direction. A first groove combined with a part of the straw is formed on the circumferential side surface of the large pipe winding roller. The first groove extends along the axial direction of the large pipe winding roller and is arranged at equal angles along the circumferential direction of the large pipe winding roller;

[0008] A cutter structure, which includes a cutter. The cutter is driven by the power device to perform reciprocating linear motion along the radial direction of the large pipe winding roller;

[0009] A pipe pushing structure, which includes a pipe pushing rod. One end of the pipe pushing rod is provided with a second groove combined with a part of the circumferential surface of the straw. The pipe pushing rod is driven by the power device to move, so as to send a single straw partially accommodated in the first groove into the pipe feeding conveyor;

[0010] The pipe feeding conveyor includes a conveyor. A plurality of stoppers are arranged on the surface of the conveyor belt of the conveyor at equal intervals along the traveling direction of the conveyor belt. The space between adjacent stoppers is used to accommodate a single straw.

[0011] The utility model winds the straw belt through a large winding tube roller, cuts the film between the straw belts by a cutter structure, and then pushes the straws into adjacent stoppers on the conveyor belt during the pipe feeding through a push pipe structure, so as to output the straws with the cut film at equal intervals; it realizes multiple cuts and one placement, that is, continuously cuts out multiple straws and then centrally places them at one time, integrates multiple high-speed pipe cutting machines into one, greatly reduces the equipment volume and cost, and can improve the equipment production capacity more.

[0012] Furthermore, there are two groups of guiding blocks arranged outside the large winding tube roller. The sides of the two groups of guiding blocks facing the large winding tube roller are arc surfaces concentric with the large winding tube roller, and a guiding channel for accommodating the straw belt is formed between the inner sides of the guiding blocks and the outer side of the large winding tube roller.

[0013] When the straws are wound by the large winding tube, the movement of the straws is guided through the guiding channel, so that the straws are always fixed in the first groove, thereby avoiding the straws from tilting outwards and falling.

[0014] Furthermore, a baffle is arranged on one side of the conveyor close to the pipe cutting assembly, and a pipe supporting block is arranged below the baffle. The baffle, the pipe supporting block and the conveyor belt form a pipe feeding channel.

[0015] The transportation of multiple single straws during the pipe feeding is guided through the pipe feeding channel, and the pipe supporting block supports the straws, so as to ensure that the straws can be transported by the conveyor to the pipe outlet of the conveyor and discharged.

[0016] Furthermore, a pipe inlet for the straws to enter the pipe feeding channel is opened at the position of the baffle corresponding to the push pipe rod, and an avoidance groove for the movement of the push pipe rod is arranged on one side of the pipe inlet.

[0017] The push pipe rod sends the straws into the pipe feeding channel from the pipe inlet, so that when the straws are sent into the pipe feeding channel, their bottoms can be supported by the pipe supporting block, thereby avoiding the straws from falling after the push pipe rod is loosened after the straws are sent in.

[0018] Furthermore, an annular groove surrounding the large winding tube roller for one week is opened on the circumferential surface of the large winding tube roller corresponding to the push pipe rod, and this annular groove is used to accommodate one end of the push pipe rod provided with a second groove.

[0019] Before the straws are sent into the pipe feeding channel, one end of the push pipe rod provided with the second groove is accommodated in the annular groove. When the straws rotate to this end position, the push pipe rod moves to send the straws into the pipe feeding channel, and then returns to the annular groove, which is convenient for the straws to move to the position of the second groove, avoids interfering with the rotation of the straws and the movement of the push pipe rod, and at the same time makes the structure of the device more compact.

[0020] Further, the pipe cutting assembly further includes a pre-feed pipe roller, and a first groove is formed on the circumferential side surface of the pre-feed pipe roller. The first groove extends along the axial direction of the pre-feed pipe roller and is arranged at equal angles along the circumferential direction of the pre-feed pipe roller.

[0021] The pre-feed pipe roller rotates synchronously with the large coil pipe roller, so as to reduce the tension of the straw belt between the pre-feed pipe roller and the large coil pipe roller.

[0022] Further, the pipe cutting assembly further includes

[0023] a straw belt twister, and a twisting channel is arranged inside the straw belt twister. The twisting channel twists at equal angles from the inlet pipe opening to the outlet pipe opening, so that a preset included angle is formed between the inlet pipe opening and the outlet pipe opening;

[0024] a straw guide groove, and the straw guide groove is arranged at the outlet pipe opening of the above-mentioned straw belt twister.

[0025] Further, the pipe cutting machine further includes a pipe feeding assembly, and the pipe feeding assembly is arranged corresponding to the inlet pipe opening of the above-mentioned straw belt twister. The pipe feeding assembly includes a pipe feeding roller, and a first groove is formed on the circumferential side surface of the pipe feeding roller. The first groove extends along the axial direction of the pipe feeding roller and is arranged at equal angles along the circumferential direction of the pipe feeding roller. An inlet pipe slideway is arranged outside the pipe feeding roller.

[0026] Further, a first straw belt buffer bin is arranged on one side of the pipe feeding assembly away from the straw belt twister.

[0027] Further, a second straw belt buffer bin is arranged between the pipe feeding assembly and the straw belt twister.

[0028] The whole section of the straw belt is wound from the first straw belt buffer bin onto the pipe feeding roller. The first groove on the pipe feeding roller can hold the straws, so as to wind the straw belt into the second straw belt buffer bin to cache a part of the straws; the pre-feed pipe roller rotates synchronously with the large coil pipe roller, so as to reduce the tension of the straw belt between the pre-feed pipe roller and the large coil pipe roller. The pre-feed pipe roller pulls the straws in the second straw belt buffer bin into the straw belt twister, twists the straws by 90° to twist the lying straws into upright straws and then enters the straw guide groove. The straw guide groove is equipped with a straw material shortage detection sensor to detect whether the straw belt is short of materials or broken.

[0029] The utility model has the following advantages:

[0030] The utility model winds the straw belt through a large winding tube roller, cuts the film between the straw belts by a cutter structure, and then pushes the straws into adjacent stoppers on the conveyor belt during the pipe feeding and conveying through a pushing pipe structure, so as to output the straws with the cut film at equal intervals; realizing multi-cut and one-drop, that is, continuously cutting out multiple straws and then concentrating and dropping them at one time, integrating multiple high-speed pipe cutting machines into one, greatly reducing the equipment volume and cost, and improving the equipment production capacity.

[0031] When the straws are wound through the large winding tube, the movement of the straws is guided through the guiding channel, so that the straws are always fixed in the first groove, thus preventing the straws from tilting and falling outwards. The conveying of multiple single straws during the pipe feeding and conveying is guided through the pipe feeding channel, and the supporting block supports the straws, thus ensuring that the straws can be conveyed by the conveyor to the pipe outlet of the conveyor and discharged.

[0032] The pushing pipe rod sends the straws into the pipe feeding channel from the inlet pipe, so that when the straws are sent into the pipe feeding channel, their bottoms can be supported by the supporting block, thus preventing the straws from falling after the pushing pipe rod is loosened after the straws are sent in. Before the straws are sent into the pipe feeding channel, the end of the pushing pipe rod provided with the second groove is received into the annular groove. When the straws rotate to this end position, the pushing pipe rod moves to send the straws into the pipe feeding channel, and then returns to the annular groove, facilitating the straws to move to the position of the second groove, avoiding interference with the rotation of the straws and the movement of the pushing pipe rod, and making the structure of the device more compact.

[0033] The whole straw belt is wound from the first straw belt buffer bin onto the inlet pipe roller. The first groove on the inlet pipe roller can hold the straws to wind part of the straws in the straw belt into the second straw belt buffer bin for buffering; the pre-pipe feeding roller rotates synchronously with the large winding tube roller to reduce the tension of the straw belt between the pre-pipe feeding roller and the large winding tube roller. The pre-pipe feeding roller pulls the straws in the second straw belt buffer bin into the straw belt torsion device, twists the straws by 90° to twist the lying straws into upright straws and then enters the straw guiding groove. The straw guiding groove is equipped with a straw material shortage detection sensor to detect whether the straw belt is short of materials or broken. Description of the Drawings

[0047] As described in the background art, the existing pipe cutting machines on the market are single-cut and single-discharge, that is, cut one straw and put one straw, with low efficiency.

[0048] Embodiment 1:

[0049] Therefore, to solve the above technical problems of the prior art, the present embodiment provides a high-speed pipe cutting machine herein, as Figure 1 、 2 shown. The high-speed pipe cutting machine includes a pipe cutting assembly 500 and a pipe feeding conveyor 400. The pipe cutting assembly 500 continuously feeds a single straw cut by the pipe cutting assembly 500 into the pipe feeding conveyor, so that the pipe feeding conveyor sends multiple straws to the outlet end of the pipe feeding conveyor.

[0050] As Figure 3 shown, the pipe cutting assembly 500 includes

[0051] a power device 560;

[0052] a first pipe coiling structure 540, which includes a large pipe coiling roller 541. The large pipe coiling roller 543 is driven by the power device 560 to rotate along its own circumferential direction. A first groove for engaging with a part of the straw is formed on the circumferential side surface of the large pipe coiling roller 541. The first groove extends along the axial direction of the large pipe coiling roller 541 and is arranged at equal angles along the circumferential direction of the large pipe coiling roller.

[0053] a cutter structure 550, which includes a cutter 552. The cutter is driven by the power device 560 to perform reciprocating linear motion along the radial direction of the large pipe coiling roller.

[0054] a pipe pushing structure 530, which includes a pipe pushing rod 531. A second groove for engaging with a part of the circumferential surface of the straw is provided at one end of the pipe pushing rod 531. The pipe pushing rod is driven by the power device to move, so as to send a single straw partially accommodated in the first groove into the pipe feeding conveyor 400.

[0055] The pipe feeding conveyor includes a conveyor 410. A plurality of stoppers 420 are provided on the surface of the conveyor belt of the conveyor. The plurality of stoppers 420 are arranged at equal intervals along the traveling direction of the conveyor belt, and a single straw is accommodated between adjacent stoppers.

[0056] As Figure 4 、 5 shown, the straw belt is wound in by the large pipe coiling roller, the film between the straw belts is cut off by the cutter structure, and then the straws are pushed into the adjacent stoppers on the conveyor belt in the pipe feeding conveyor by the pipe pushing structure, so as to output the straws with the cut film at equal intervals.

[0057] Through the present embodiment, the function of cutting multiple and discharging one is realized, that is, multiple straws are continuously cut out and then centrally discharged at one time, realizing the integration of multiple high-speed pipe cutting machines into one, greatly reducing the volume and cost of the equipment, and further improving the production capacity of the equipment.

[0058] In this embodiment, the large coiling tube roller and the conveyor can both be vertically arranged. The power device can be selected as a motor, and the power device can be connected to the cutter structure and the tube pushing structure through a synchronous transmission mechanism, so as to realize the synchronous movement of the tube pushing rod and the cutter. The cutter structure can be connected to the synchronous transmission mechanism through a second cam link structure 553. In addition, the cutter structure can also include a fixed seat 551, and the cutter is linearly slidably connected to the fixed seat through a slide rail guiding structure. The tube pushing rod can be connected to the synchronous transmission mechanism through a first cam link structure 532 to realize the reciprocating swing of the tube pushing rod.

[0059] In this embodiment, as Figure 3 shown, there are two groups of guiding blocks 542 arranged outside the large coiling tube roller. The two groups of guiding blocks are arc surfaces concentric with the large coiling tube roller on the side facing the large coiling tube roller, and a guiding channel for accommodating the straw belt is formed between the inner side of the guiding block and the outer side of the large coiling tube roller.

[0060] When the straw is wound into the large coiling tube through the guiding channel, the movement of the straw is guided, so that the straw is always fixed in the first groove, thereby preventing the straw from tilting outwards and falling.

[0061] In this embodiment, as Figure 2 shown, a baffle 430 is provided on one side of the conveyor 410 close to the pipe cutting assembly, and a pipe supporting block 440 is provided below the baffle. The baffle, the pipe supporting block and the conveyor belt form a pipe feeding channel.

[0062] The feeding of multiple single straws during the pipe feeding process is guided through the pipe feeding channel, and the pipe supporting block supports the straws, so as to ensure that the straws can be conveyed by the conveyor to the pipe outlet of the conveyor for discharge.

[0063] As Figure 1 shown, a straw inlet for the straw to enter the pipe feeding channel is opened on the baffle corresponding to the position of the pipe pushing rod, and an avoidance groove for the movement of the pipe pushing rod is provided on one side of the straw inlet.

[0064] The pipe pushing rod sends the straw into the pipe feeding channel, so that when the straw is sent into the pipe feeding channel, its bottom can be supported by the pipe supporting block, thereby preventing the straw from falling after the pipe pushing rod is released after the straw is sent in.

[0065] As Figure 3 shown, an annular groove surrounding the large coiling tube roller for one week is opened on the circumferential surface of the large coiling tube roller corresponding to the pipe pushing rod, and the annular groove is used to accommodate one end of the pipe pushing rod provided with a second groove.

[0066] Before the straw is fed into the tube feeding channel, the end of the pushing rod with the second groove is received into the annular groove. When the straw rotates to this end position, the pushing rod moves to feed the straw into the tube feeding channel and then returns to the annular groove, facilitating the straw to move to the position of the second groove, avoiding interference with the rotation of the straw and the movement of the pushing rod, and making the structure of the device more compact.

[0067] As Figure 4 shown, the tube cutting assembly further includes a pre-feeding tube roller. A first groove is formed on the circumferential side surface of the pre-feeding tube roller. The first groove extends along the axis direction of the pre-feeding tube roller and is arranged at equal angles along the circumferential direction of the pre-feeding tube roller.

[0068] The pre-feeding tube roller rotates synchronously with the large coiling tube roller, reducing the tension of the straw belt between the pre-feeding tube roller and the large coiling tube roller.

[0072] The straw belt twister can twist the straw by 90° to twist the straw in a lying state into an upright straw and then enter the straw guiding groove.

[0073] In this embodiment, the pre-feeding tube roller, the large coiling tube roller, the cutter, and the pushing rod are all driven by a servo motor, and the 4 mechanisms run mechanically synchronously.

The tube feeding assembly 300 includes a tube feeding roller 310. A first groove is formed on the circumferential side surface of the tube feeding roller 310. The first groove extends along the axis direction of the tube feeding roller and is arranged at equal angles along the circumferential direction of the tube feeding roller. An inlet pipe slideway 320 is arranged outside the tube feeding roller 310.

[0076] A first straw belt buffer bin 100 is arranged on the side of the tube feeding assembly away from the straw belt twister.

[0077] A second straw belt buffer bin 200 is provided between the inlet pipe assembly and the straw belt twister.

[0078] The entire straw belt is wound from the first straw belt buffer bin onto the inlet pipe roller. The first groove on the inlet pipe roller can hold the straws to wind part of the straw belt into the second straw belt buffer bin for buffering; the pre-feed pipe roller and the large pipe winding roller rotate synchronously, reducing the tension of the straw belt between the pre-feed pipe roller and the large pipe winding roller. The pre-feed pipe roller pulls the straws in the second straw belt buffer bin into the straw belt twister, twisting the straws by 90° to twist the lying straws into upright straws and then into the straw guide groove. The straw guide groove is equipped with a straw material shortage detection sensor 580 to detect whether the straw belt is short of materials or broken.
