Description

Technical Field

[0001] The utility model relates to the technical field of raw material opening, combing and breaking, in particular to a double-row tooth distribution fixed U-shaped toothed belt and a toothed roller shaft. Background Art

[0002] Existing equipment for opening, combing and breaking raw materials will use toothed roller shafts, such as openers or carding machines for combing fibers, or toothed roller crushers for crushing food such as meat, or toothed roller grinders for crushing tobacco or feed.

[0003] In the prior art, for example, the surface of the toothed roller shaft used in pre-spinning machinery such as openers and carding machines needs to be grooved for inlaying rack clothing, which requires high groove precision, complex manufacturing process, high manufacturing cost and time-consuming, cumbersome procedures, and the raw materials must be thick. The grooves on the roller shaft are damaged by the extrusion force of the cogs, resulting in a short roller shaft life, which must be replaced after two years. After the single row of teeth on the roller shaft is wound, the relative positions of the adjacent rows of teeth are easily offset and cannot be fixed, resulting in uneven force on the raw materials and low qualified rate of the finished products. Moreover, tooth replacement is troublesome and time-consuming. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, one of the purposes of the utility model is to provide a double-row tooth distribution fixed U-shaped tooth belt that can replace the traditional rack needle clothing and a tooth roller shaft wrapped with the double-row tooth distribution fixed U-shaped tooth belt.

[0005] One of the purposes of the utility model is achieved by the following technical solution:

[0006] A double-row tooth distribution fixed U-shaped tooth belt, comprising a bottom plate and a tooth portion standing above the bottom plate, and the bottom plate has a certain elasticity;

[0007] The tooth portion is composed of a tooth portion group 1 and a tooth portion group 2, which are respectively erected on the edges of both sides of the bottom plate, the bottom plate and the tooth portion are integrally formed to form a U-shaped belt, and the tooth portion group 1 and the tooth portion group 2 are composed of a plurality of continuously arranged tooth-shaped structures;

[0008] The double-row tooth distribution fixed U-shaped toothed belt is made of metal.

[0009] Traditional rack clothing has no bottom belt to attach to, and a high-precision groove needs to be opened on the roller surface. The groove needs to be consistent with the base thickness of the rack clothing so that the rack clothing can be just embedded in the groove. This makes the production process of traditional rollers cumbersome and complicated, and the raw materials must also be thickened, which is time-consuming, labor-intensive and costly. In addition, the groove is easily damaged by the squeezing force of the cogging, resulting in low roller utilization, which generally needs to be replaced every two years. By using this double-row tooth distribution fixed U-shaped toothed belt to replace the traditional rack clothing, there is no need to open a high-precision groove on the roller surface, and the bottom belt can be directly wrapped or coiled around the roller surface. The roller will not be discarded due to groove damage. In principle, the roller can be used all the time, and only the toothed belt outside the roller needs to be replaced each time, without discarding the roller, which greatly improves the utilization rate of the roller.

[0010] The installation method of the double-row tooth distribution fixed U-shaped toothed belt is that it can be directly wrapped or coiled on the surface of the shaft body. It only needs to punch holes at the head and tail to fix it. In the middle, you can selectively punch holes at the position that needs reinforcement. Drill installation holes directly on the bottom plate and through holes through the shaft body, and then fix it with fasteners.

[0011] Moreover, the double-row tooth distribution fixed U-shaped tooth belt has a double row of teeth, which greatly improves the tooth changing speed. Compared with the traditional single-row rack needle clothing, it is equivalent to changing two rows of teeth at one time, saving time and effort.

[0012] Preferably, the tooth group 1 and the tooth group 2 have the same appearance;

[0013] A point is selected at any position of the tooth group 1 and is marked as a. A point in the tooth group 2 with the same relative position as a is marked as b. A point perpendicular to the tooth group 2 is marked as c. A distance is set between b and c, so that the relative positions of the tooth group 1 and the tooth group 2 are fixed and staggered.

[0014] Or b and c overlap, so that the relative positions of the tooth group 1 and the tooth group 2 are fixed and distributed side by side.

[0015] Preferably, the tooth structures of the double-row tooth distribution fixed U-shaped toothed belt are the same;

[0016] The tooth-shaped structures are connected end to end, or the same spacing distance is set between two adjacent tooth-shaped structures;

[0017] By setting a distance between b and c, the tooth group one and the tooth group two can always maintain a fixed relative position staggered situation. The purpose is to allow the tooth profile structures of the tooth group one and the tooth group two to always maintain a staggered distribution, which can avoid the situation where the relative positions of two adjacent rows of teeth gradually shift and cannot be fixed after the traditional single-row tooth winding; the relative staggering of the two rows of tooth profile structures can reduce the relative gap in the lateral direction of the tooth profile structure, so that the opening and combing force in all directions of the tooth roller axis is uniform, and the discharge effect is more ideal.

[0018] Preferably, the base plate is provided with mounting holes, and the mounting holes can be matched with fasteners to install and fix the base plate; the mounting holes can be punched while producing the double-row tooth distribution fixed U-shaped toothed belt, or the mounting holes can be directly punched on the base plate and through holes can be punched through the shaft body while winding or coiling the roller, and then fixed with fasteners.

[0019] A toothed roller shaft comprises a shaft body, and a double-row toothed fixed U-shaped toothed belt as described above is installed on the outer side of the shaft body; the installation method is not limited, and one toothed belt can be spirally wound from end to end, multiple toothed belts can be spirally wound, multiple toothed belts can be circularly wound around the roller body, multiple toothed belts can be obliquely wound, etc.

[0020] Preferably, a through hole corresponding to the mounting hole on the base plate is opened on the surface of the shaft body, and one end of a fastener passes through the mounting hole and is located in the through hole so that the base plate is set on the shaft body; the through hole on the shaft body is generally drilled when installing a double-row tooth distribution fixed U-shaped toothed belt. When the base belt is wrapped around the surface of the shaft body, a mounting hole can be directly drilled on the base plate 1 and a through hole can be drilled through the shaft body, and then fixed with a fastener; or when installing a base belt that already has a mounting hole, a through hole corresponding to the mounting hole is drilled on the surface of the shaft body, and then fixed with a fastener; the fastener on the through hole can be set at a suitable position that needs to be reinforced according to the situation.

[0021] Preferably, a placement groove corresponding to the bottom plate is provided on the surface of the shaft body; the placement groove can prevent the bottom belt from being displaced. The placement groove only serves to fix the U-shaped toothed belt, does not require high precision, and is relatively simple to manufacture.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By wrapping the double-row tooth distribution fixed U-shaped tooth belt outside the roller shaft, the traditional tooth roller shaft manufacturing process becomes simpler and no longer cumbersome, the material saving efficiency is improved, and the roller shaft surface does not need to open high-precision grooves, which reduces the manufacturing cost and process. The grooves of the traditional roller shaft are damaged due to the force of the rack. The grooves of the tooth roller shaft of this scheme are only used to position the placement grooves of the double-row tooth distribution fixed U-shaped tooth belt, so the grooves will not be damaged, which greatly extends the life of the roller shaft. The speed of replacing teeth is twice as fast. The original single-row teeth are now double-row teeth, which is equivalent to replacing two rows of teeth at one time, and the tooth packing efficiency is significantly improved. The design of double-row teeth can make the relative arrangement positions of the two rows of teeth fixed and staggered, avoiding the situation that the relative positions of the adjacent two rows of teeth gradually shift and cannot be fixed after the original single-row teeth are wound. The loosening and combing force of the tooth roller shaft in all directions is uniform, and the discharge effect is more uniform and ideal.

[0024] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model, it can be implemented in accordance with the contents of the specification.

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0036] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] like Figure 2-Figure 6 As shown, a double-row tooth distribution fixed U-shaped toothed belt is made of metal, including a base plate 1 and a tooth portion 2 standing above the base plate, and the base plate 1 has a certain elasticity, and the tooth portion is divided into a tooth group 1 23 and a tooth group 2 24, which stand on the edges of both sides of the base plate 1 respectively. The base plate 1 and the tooth portion 2 are integrally formed to form a U-shaped belt, and the tooth group 1 23 and the tooth group 2 24 are composed of a plurality of continuously arranged tooth structures 21.

[0039] Moreover, the bottom plate 1 may be provided with a mounting hole 11, and the mounting hole 11 may be adapted to the fastener to install and fix the bottom plate 1. The mounting hole 11 may be directly drilled on the bottom plate 1 while winding or circling the shaft body 3, and a through hole 32 may be drilled through the shaft body 3. The location to be reinforced may be selected according to actual conditions, and then fixed with a fastener; the mounting hole 11 may also be drilled while manufacturing a double-row tooth distribution fixed U-shaped toothed belt.

[0040] There is no specific limit on the width and length of the bottom plate 1, so the bottom plate 1 can be wide or narrow, and the toothed belt can be long or short. There is no specific limit on the thickness of the material, and the thickness of the material can be customized according to the performance of the loosened raw material.

[0041] Secondly, the tooth-shaped structure 21 can have various shapes without specific restrictions. The tooth-shaped structure 21 can be customized according to requirements. The tooth-shaped structures 21 can be the same or different. The spacing between the tooth-shaped structures 21 can be the same or different, or they can be connected end to end.

[0042] Therefore, in actual use, since there is no need to open high-precision grooves, the shaft body 3 will not be discarded due to groove damage, and the shaft body 3 can be used all the time. Each time the teeth are replaced, only the upper teeth need to be replaced, which greatly improves the utilization rate of the shaft body 3 and extends the life of the shaft body 3. The double-row teeth have doubled the efficiency of the traditional single-row teeth.

[0043] like Figure 3-Figure 5 As shown, each tooth-shaped structure 21 is the same, each tooth-shaped structure 21 is connected end to end, or the same spacing distance is set between two adjacent tooth-shaped structures 21, and the points at the same position on the tooth group 1 23 and the tooth group 2 24 are set with a staggered distance so that they are fixedly staggered or relatively parallel. For example, a point is taken at any position of the tooth group 1 23 and is marked as a, and the point at the same relative position corresponding to a in the tooth group 2 24 is marked as b, and a point perpendicular to the tooth group 2 is marked as c, and a distance is set between b and c, or b and c coincide. There is no specific restriction on the distance set between b and c, and the distance can be set according to the situation.

[0044] Therefore, in actual use, by setting the tooth group 1 23 and the tooth group 2 24 to be fixedly offset, the relative lateral gap of the tooth structure can be effectively reduced, and the probability of the raw material being loosened and combed during the processing can be effectively increased, making the discharge effect more uniform and ideal.

[0045] like Figure 1-Figure 9 As shown, a toothed roller shaft comprises a shaft body 3, and the outer side of the shaft body 3 is provided with the above-mentioned double-row tooth distribution fixed U-shaped toothed belt.

[0046] A through hole 32 corresponding to the mounting hole 11 on the bottom plate 1 may be opened on the surface of the shaft body 3 , and one end of a fastener passes through the mounting hole 11 and is located in the through hole 32 , so that the bottom plate 1 is set on the shaft body 3 .

[0047] A placement groove 31 corresponding to the width of the bottom belt can be opened on the surface of the shaft body 3 to prevent the bottom belt from being displaced.

[0048] There is no limitation on the way of installing the double-row tooth distribution fixed U-shaped tooth belt on the outer side of the shaft body. It can be spirally wound from one end to the other, multiple spirally wound, multiple circularly wound around the roller body, multiple obliquely wound, etc. The spacing between two adjacent rows can be selected according to the actual situation.

[0049] The through hole 32 on the shaft body 3 is generally opened when installing a double-row tooth distribution fixed U-shaped toothed belt. When the bottom belt 1 is wound on the surface of the shaft body 3, the installation hole 11 can be directly drilled on the bottom plate 1 and the through hole 32 can be drilled through the shaft body 3, and then fixed with a fastener; or when installing the bottom belt 1 with the installation hole 11, a through hole 32 can be drilled on the surface of the shaft body 3 corresponding to the installation hole 11, and then fixed with a fastener. The fastener on the through hole 32 can be set at a suitable position that needs to be reinforced according to the situation.

[0050] The placement groove 31 on the surface of the shaft body 3 can prevent the bottom belt from shifting. This placement groove 31 is only used to fix the U-shaped toothed belt, does not require high precision, and is simpler to manufacture than traditional grooves with high precision requirements.

[0051] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
