Description

Technical Field

[0001] The present application relates to the technical field of tobacco shred conveying equipment, and in particular to a shred tube fixing bracket. Background Art

[0002] In the production process of cigarette factories, wind pressure conveying is usually used for the transportation of tobacco. A tobacco tube pipeline is set between the cigarette making equipment and the tobacco supply equipment. The end of the tobacco tube pipeline forms a negative pressure under the action of the fan, so that the tobacco at the tobacco supply equipment is transported to the cigarette making equipment along the tobacco tube under the action of the pressure difference. This transportation method is highly efficient, but it also has certain disadvantages in actual application. For example, under the action of the fan, a pressure difference is generated at both ends of the tobacco tube pipeline. Under the action of the pressure difference and the impact of tobacco, the tobacco tube produces axial movement, especially at the turning position of the tobacco tube. The tobacco tube at this position is subjected to mutually perpendicular forces in two directions. In addition, the influence of the tobacco tube's own gravity causes the tobacco tube to shake to a certain extent. If the shaking phenomenon is serious, it may even affect the connection strength of the interface connection of the tobacco tube, and there is a risk of air leakage in the tobacco tube pipeline.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] like Figure 1-Figure 5 As shown, an embodiment of the present application provides a wire tube fixing bracket, which is used for fixing the wire tube. The wire tube is specifically a wire tube pipeline used for wind pressure conveying of tobacco in a cigarette factory. When the wire tube pipeline is conveyed by wind pressure, under the action of the pressure difference at both ends of the pipeline and the impact of tobacco on the inside of the wire tube, the wire tube pipeline is prone to axial movement. In addition, due to the influence of the wire tube pipeline's own gravity, the wire tube pipeline is prone to shaking when conveying tobacco, especially at the turning position of the pipeline. The turning angle of the wire tube pipeline is usually 90 degrees, so this part will generate two directions perpendicular to each other, the pipeline shaking more violently, and even affect the connection strength of the pipeline interface connection, so that the sealing performance of the connection is reduced, and there is a hidden danger of air leakage in the wire tube pipeline. Once the air leaks, it will affect the efficiency of tobacco conveying. The wire tube fixing bracket provided by the present application is to stabilize and strengthen the wire tube pipeline to slow down or even eliminate the shaking of the wire tube pipeline, improve the overall and local stability of the pipeline, eliminate the hidden danger of air leakage in the pipeline, and ensure the efficiency of wind pressure conveying of tobacco.

[0025] The wire tube fixing bracket includes a support part 100 and a fixing part, and the support part 100 and the fixing part are connected to each other. The support part 100 is installed at a preset position through the fixing part to stabilize the wire tube. The fixing part can be a component connected to the wall, or a component connected to the indoor ceiling. Preferably, the fixing part is a component directly placed on the ground and has a certain dead weight, and the setting and adjustment of the fixing part will be more convenient. The wire tube pipeline is supported by the fixing part and the support part 100 to improve the stability of the wire tube pipeline during operation. More preferably, the fixing part includes a base 201, and a threaded rod 202 is arranged on the base 201. One end of the threaded rod 202 is connected to the base 201, and the other end of the threaded rod 202 is connected to the base 201. One end is connected to the support part 100, and the support part 100 is used to connect with the wire tube. The base 201 is disc-shaped and has a certain self-weight. The base 201 can be a disc made of metal. In this way, after the wire tube pipeline is supported and stabilized, on the one hand, the supporting effect can eliminate the negative impact of the self-weight of the wire tube pipeline and avoid the sinking and collapse of the pipeline. On the other hand, due to the certain self-weight of the base 201, plus the horizontal interaction force between the disc-shaped base 201 and the ground, the horizontal direction of the wire tube will also have an effect of suppressing shaking. By reducing the length of the threaded rod 202 and appropriately increasing the diameter of the base 201, the suppression effect of the shaking of the wire tube in the horizontal direction can be improved and the stability of the overall support can be improved.

[0026] In this embodiment, the support portion 100 has a first side portion 101 and a second side portion 102, and the first side portion 101 and the second side portion 102 are positions on different sides of the support portion 100. When stabilizing the wire tube, at least the first side portion 101 faces the wire tube. Preferably, after the wire tube is stabilized by the support portion 100 and the fixing portion, the first side portion 101 faces the wire tube, and the second side portion 102 faces the fixing portion. A connecting component is provided on the first side portion 101 of the support portion 100, and the support portion 100 stabilizes the wire tube through the connecting component. Preferably, the wire tube is seated on the support portion 100 through the connecting component. In this way, under the action of the connecting component, the wire tube can be directly seated downward on the support portion 100. The matching method is simple and the operation is convenient. The operation when the support portion 100 and the wire tube are separated is also simple. The wire tube can be slightly lifted upward and then the support portion 100 is withdrawn, so that the supported position of the wire tube can be adjusted conveniently.

[0027] At this point, under the action of the disc-shaped base 201 and the support part 100, the vertical and horizontal directions of the wire tube pipeline can be effectively stabilized, the shaking of the pipeline can be effectively slowed down or even eliminated, and the overall stability of the wire tube pipeline can be improved.

[0028] Preferably, the connecting component includes a carrier frame 300, on which an open notch 301 is provided, and the notch 301 faces outward and is an open opening, and the wire tube can be radially adapted into the notch 301. That is, since the notch 301 is an open opening, the wire tube can enter the notch 301 along the diameter direction and escape from the notch 301 to the outside along the diameter direction, thereby facilitating the mutual cooperation and separation of the wire tube and the carrier frame 300 and increasing the convenience during operation.

[0029] In this embodiment, under the action of the connecting component, it can be used to support the straight section of the wire tube pipeline, and can also support the turning section of the wire tube pipeline. Since the turning angle of the wire tube pipeline is usually 90 degrees, the fixed bracket is applicable to the 90-degree turning section of the wire tube pipeline for explanation. More specifically, the fixed bracket is applicable to the intersection of the vertical pipe section and the horizontal pipe section for explanation.

[0030] There are multiple carriers 300, and the multiple carriers 300 are arranged in an arc shape. The arrangement path of the multiple carriers 300 is the same as the turning path of the wire tube, so as to support the wire tube at the turning point. Preferably, the carrier 300 is a flat plate structure, and the notch 301 is located at the edge of the carrier 300 and is set in an open shape, and the notch 301 runs through both sides of the thickness direction of the carrier 300. The support part 100 is also a flat plate structure, and the first side portion 101 and the second side portion 102 are two adjacent edges on the support part 100. Preferably, the support part 100 is roughly in the shape of a right triangle, one right-angled side constitutes the second side portion 102, and the right-angled side is facing downward, and the other right-angled side is facing in the horizontal direction, and the hypotenuse is set in an inwardly concave arc shape. The concave arc-shaped hypotenuse constitutes the first side portion 101, and the direction of the arc is the same as the direction of the turning point of the wire tube. A plurality of support frames 300 are arranged along the hypotenuse of the arc, and a bayonet 302 is provided on the support frame 300. The bayonet 302 is located at the edge of the support frame 300 and is open. In this embodiment, the support frame 300 is roughly arranged in an isosceles trapezoidal shape, and the side where the notch 301 is located is a longer bottom side, and the side where the bayonet 302 is located is a shorter top side, so that the support frame 300 forms an axially symmetrical structure relative to the line connecting the midpoint of the top side and the midpoint of the bottom side. The support frame 300 can ride on the first side portion 101 of the support portion 100 through the bayonet 302. In this way, the support frame 300 is more balanced and stable on the support portion 100, thereby improving the stability of the supporting wire tube.

[0031] After the wire tube is stabilized, the supporting portion 100 which is roughly in the shape of a right triangle makes the center of gravity of the whole more stable.

[0032] In this embodiment, the width of the bayonet 302 is slightly larger than the thickness of the support portion 100, and the difference between the width of the bayonet 302 and the thickness of the support portion 100 is 1-2 mm. The length of the bayonet 302 is larger than the width of the bayonet 302, so that the first side portion 101 of the support portion 100 can be partially adapted to a sufficient spacing in the bayonet 302, thereby improving the strength of the connection. A locking member is provided between the carrier frame 300 and the support portion 100, and the carrier frame 300 and the support portion 100 are further connected by the locking member, thereby limiting the carrier frame 300 and the support portion 100 from being disengaged. Preferably, connecting plates 303 are provided on both edges of the carrier frame 300 along the length of the bayonet 302. The connecting plates 303 are provided in a plate shape. The connecting plates 303 and the carrier frame 300 are perpendicular to each other. After the first side portion 101 of the support portion 100 is partially adapted to the bayonet 302, the connecting plates 303 on both sides are respectively located on both sides of the support portion 100. The connecting plates 303 and the support portion 100 are connected by a locking member. The locking member can be a bolt. The number of bolts is at least two, so as to improve the stability of the connection between the carrier frame 300 and the support portion 100.

[0033] Preferably, the notch 301 on the supporting frame 300 is arranged in an arc shape, the arc shape of the notch 301 is adapted to the outer shape of the wire tube, and the arc surrounding angle of the notch 301 is not greater than 180 degrees. The arc surrounding angle of the notch 301 is preferably 180 degrees, which facilitates the radial adaptation of the wire tube into the notch 301 and the escape from the notch 301, while enabling a stable limiting effect to be formed between the notch 301 and the wire tube.

[0034] In this embodiment, two support frames 300 are set as an example for explanation. When stabilizing the intersection of the vertical wire tube and the horizontal wire tube, the fixed bracket is placed as a whole below the turning point of the wire tube, so that the outer circle of the turning point of the wire tube faces the notch 301 of the support frame 300 and fits into the notch 301. One of the support frames 300 is against the bottom of the turning point of the wire tube, and the other support frame 300 is against the upper position of the turning point of the wire tube. In this way, under the action of friction, the wire tube can be supported in the vertical direction and the shaking of the wire tube in the horizontal direction can be suppressed. In order to improve the matching strength between the support frame 300 and the wire tube, a rubber pad can be set at the notch 301 of the support frame 300 or a rubber belt can be wrapped around the turning area of ​​the wire tube to increase the friction matching strength between the support frame 300 and the wire tube and improve the stability of the overall support.

[0035] In this embodiment, a reduction groove 304 is provided on the support frame 300 at the edge of the notch 301. The reduction groove 304 runs through both sides of the thickness of the support frame 300. The reduction groove 304 and the notch 301 form a connected structure. The function of the reduction groove 304 is to reduce the weight of the support frame 300, reduce the overall weight level of the equipment, help lower the center of gravity, and improve the overall stability. The arc-shaped surrounding angle of the notch 301 occupied by the reduction groove 304 is not greater than 1 / 5 of the surrounding angle of the notch 301 to ensure that there is sufficient contact and matching area between the support frame 300 and the wire tube.

[0036] Preferably, the threaded rod 202 can be axially movably installed at the bottom of the support part 100, and a sleeve 400 for easy screwing is provided on the threaded rod 202. The sleeve 400 and the threaded rod 202 are matched by threads. The sleeve 400 is screwed so that the sleeve 400 is raised or lowered along the threaded rod 202. The support part 100 is located on the threaded rod 202 through the sleeve 400, and the height of the support part 100 can be easily adjusted by screwing the sleeve 400, thereby improving the adaptability of the equipment and the supporting effect on the wire tube. In this embodiment, the threaded rod 202 is vertically connected to the top of the base 201, and the second side portion 102 of the support part 100 faces downward. A connecting hole 103 is provided at the bottom of 02, and the axis of the connecting hole 103 is also vertically arranged. The aperture of the connecting hole 103 is slightly larger than the outer diameter of the threaded rod 202. Preferably, the difference between the aperture of the connecting hole 103 and the outer diameter of the threaded rod 202 is 1-2 mm, so that the threaded rod 202 can axially and circumferentially move into the connecting hole 103. A through groove 104 is provided on the support portion 100, and the through groove 104 penetrates both sides of the support portion 100 in the thickness direction at the position of the connecting hole 103. Preferably, the through groove 104 has a certain length, and the length direction of the through groove 104 is horizontally arranged. The through groove 104 penetrates the support portion 100 in the middle of the axial direction of the connecting hole 103. The kit 400 It can be a hand wheel, which can be adapted into the through groove 104 and can rotate in the through groove 104. A threaded hole is set in the middle of the hand wheel, and the threaded hole in the middle of the hand wheel is threadedly matched with the threaded rod 202. Through the mutual cooperation of the hand wheel and the through groove 104, the support part 100 is seated on the hand wheel, and the connection between the support part 100 and the threaded rod 202 is realized. Rotating the hand wheel can adjust the height of the hand wheel on the threaded rod 202, thereby driving the support part 100 to rise or fall, so as to realize the adjustment of the height of the support part 100. In this way, under the mutual cooperation of the hand wheel and the through groove 104, the height of the support part 100 can be conveniently adjusted, and the support part 100 and the threaded rod can be increased to a certain extent. The connection stability between 202 is beneficial to improving the overall stability of the equipment. In this embodiment, when connecting the threaded rod 202 and the support part 100, the handwheel is first placed in the through groove 104, and the threaded hole on the handwheel and the connecting hole 103 are made coaxial, and then the threaded rod 202 is rotated and inserted from the bottom opening of the connecting hole 103. As for the width of the through hole, the width of the through hole is slightly larger than the axial thickness of the handwheel, which will not interfere with the rotation of the handwheel. Moreover, when the support part 100 is skewed, the handwheel and the through groove 104 can also play a mutual locking limiting effect, thereby improving the overall stability. Preferably, the difference between the width of the through groove 104 and the axial thickness of the handwheel is 1-2 mm.

[0037] More preferably, a thickened portion 105 is provided in the area of ​​the support portion 100 corresponding to the connecting hole 103, and the thickness of the thickened portion 105 is greater than the thickness of the remaining areas on the support portion 100. In this way, the structural strength at the connecting hole 103 can be increased, and the matching stability between the threaded rod 202 and the support portion 100 can be further increased, thereby avoiding fatigue damage to the local structure of the support portion 100.

[0038] The support portion 100 and the support frame 300 of the present application adopt a plate-like structure, which can improve the structural strength of the components and improve the stability of the wire tube support.

[0039] The threaded rod 202 is preferably connected to the center position of the base 201. The base 201 is disc-shaped and made of metal. After supporting the wire tube, when the wire tube tends to shake in the horizontal direction, the threaded rod 202 tends to tilt, and the base 201 tends to tilt on one side. Due to the self-weight of the base 201, the self-weight of the support part 100 and the threaded rod 202, and the downward pressure of the wire tube, the base 201 can effectively suppress the tilting of one side, thereby suppressing the horizontal shaking intensity of the wire tube, which is beneficial to reduce the horizontal shaking of the wire tube.

[0040] The working principle of the present application is as follows: when supporting the wire tube, first adapt the handwheel to the through groove 104, and make the threaded hole of the handwheel and the connecting hole 103 remain coaxial, then screw the threaded rod 202 through the connecting hole 103 and the threaded hole on the handwheel, and then install the two supporting frames 300 on the arc-shaped first side portion 101 of the support part 100 by bolts, and then move the device as a whole to the bottom of the turning point of the wire tube, and then further adjust the position of the device as a whole and adjust the height of the support part 100 by screwing the handwheel, so that the two supporting frames 300 are supported on the outer circle of the turning point of the wire tube. In order to improve the supporting effect on the wire tube, the lower supporting frame 300 can be close to the horizontal pipe section of the wire tube, and the upper supporting frame 300 can be close to the vertical pipe section of the wire tube, so as to improve the bearing effect of the wire tube in the vertical direction and the effect of suppressing the shaking of the wire tube in the horizontal direction.
