Description

Technical Field

[0001] This utility model belongs to the field of treadmill roller processing technology, and in particular relates to a treadmill roller pushing and cutting device. Background Technology

[0002] Treadmill rollers are the roller shafts on a treadmill that drive the running belt. During operation, when the motor on the treadmill drives the roller shaft to rotate, the treadmill belt on the roller shaft is driven, and the operator runs on the treadmill belt.

[0003] The production process of treadmills includes the production of roller shafts. Specifically, the roller shaft is made by cutting steel cylinder blanks of a certain length into sections to form a specific length. After subsequent processing, including end treatment, polishing, and correction, the finished roller shaft is obtained and then installed on the treadmill.

[0004] During the production of roller shafts, it is necessary to cut the slightly longer roller steel billets. During the cutting process, operators need to continuously push the roller steel billets manually and cut them segment by segment. During the slitting process, operators use a cutting machine to cut the rollers. During the cutting process, because the cutting wheel applies downward cutting pressure to the rollers, the feeding operator needs to keep the rollers stable to prevent them from tilting up during the cutting process.

[0005] Therefore, the existing technology using manual pushing is inefficient for cutting, requires operators to constantly support the steel cylinder billet, and results in uneven cuts.

[0006] Therefore, in actual operation, operators often place the steel billet on the material bed and push it, and install a guide structure on the material bed to push it, so as to increase the stability of pushing the steel cylinder billet and ensure the accuracy of cutting.

[0007] However, during the same operation, the operator needs to frequently push the steel billet. In addition to the low efficiency of pushing and cutting, the steel billet is repeatedly rubbed on the material table, resulting in wear marks on the surface of the steel billet.

[0008] Meanwhile, the manual pushing method also has drawbacks, namely, certain safety hazards during the cutting process, especially when the cutting wheel presses down to cut if the operator fails to hold it firmly, causing the steel cylinder billet to be ejected. Utility Model Content

[0009] Based on the above background, the purpose of this utility model is to provide a treadmill roller pushing and cutting device.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A treadmill roller pushing and cutting device includes a material platform, a plurality of support structures for supporting roller blanks are installed on the top of the material platform, and an autonomous pushing mechanism. The autonomous pushing mechanism includes an annular dragging bracket, and a plurality of circumferentially distributed slow pushing structures are installed on the inner side wall of the annular dragging bracket. The slow pushing structure includes a slow pushing wheel bracket, and a slow pushing wheel that frictionally pushes the roller blank is rotatably connected to the slow pushing wheel bracket. A slow pushing wheel motor that drives the slow pushing wheel to rotate is installed on the slow pushing wheel bracket.

[0012] The autonomous pushing mechanism also includes a quick-push structure, which includes support arms installed on both sides of the annular drag bracket. The lower end of the support arms is equipped with a walking wheel structure, which pushes the vehicle by rolling.

[0013] Preferably, the pusher motor is equipped with a motor bracket, and the motor bracket is fixedly mounted on the pusher bracket;

[0014] The pusher bracket is fastened to the annular drag bracket by bolts.

[0015] Preferably, the support structure includes brackets fixedly installed on both sides of the top of the material platform, with rollers rotatably connected between the brackets.

[0016] Preferably, side rails are fixedly connected to both sides of the material platform; the walking wheel structure rolls on the side rails.

[0017] Preferably, the walking wheel structure includes a first horizontally arranged walking roller, and a walking roller motor for driving the walking roller is installed on the support arm;

[0018] Limiting grooves are provided on the side wall of the side track, and the traveling rollers are limited to rolling within the limiting grooves.

[0019] Preferably, the walking wheel structure further includes vertically arranged support rollers, which support the rolling motion on the top of the side track;

[0020] The support roller is rotatably connected to a roller shaft, which is fixedly mounted on the support arm.

[0021] Preferably, a roller blank guiding mechanism is installed on the top of the material platform, and the roller blank is guided through the roller blank guiding mechanism during the roller blank feeding process.

[0022] Preferably, the roller blank guiding mechanism includes a guide seat, on which a guide hole is provided, through which the blank is guided;

[0023] The top of the guide seat is equipped with a cylinder pressing structure.

[0024] Preferably, the cylinder pressing structure includes a cylinder, and the piston rod of the cylinder passes through the guide seat;

[0025] During the cutting process, the cylinder piston rod locks the roller blank.

[0026] Preferably, the pusher wheel is made of rubber, and several friction ridges are integrally formed on the outline of the pusher wheel.

[0027] This utility model has the following beneficial effects:

[0028] 1. During the working process, the steel cylinder billet passes through the four slow-pushing rollers (the slow-pushing rollers are made of rubber, and several friction protrusions are integrally formed on the outline of the slow-pushing rollers). Therefore, when driven by the slow-pushing roller motor, the four slow-pushing rollers provide frictional power to the steel cylinder billet from the top, bottom, and left and right sides, so as to slowly push the steel cylinder billet forward (or slowly pull it backward). The purpose of this method is: when the steel cylinder billet is pushed to a certain length by the cutting equipment (in the existing method, a cutting equipment is set at the front end of the material table, specifically a cutting machine), before the next wheel of the cutting machine cuts, the slow-pushing roller structure further slowly pushes or pulls the cylinder until the cut length meets the requirements.

[0029] Because the pusher wheel is made of rubber and has circumferentially distributed friction ridges (made of rubber) on it, and with the cooperation of four pusher wheels, the steel billet has a large frictional pushing force and high pushing stability.

[0030] The above structure enables the automatic pushing or pulling back of the steel cylinder blank during the cutting process. Furthermore, the rear side of the steel cylinder blank is limited by four slow-moving rollers during the cutting process, which greatly improves the safety of the cutting.

[0031] 2. The steel cylinder blank is cut over a long distance by rolling and pushing it using a traveling wheel structure. Specifically, after the steel cylinder blank is cut, the traveling wheel structure continues to push the entire device forward for further cutting, and then returns to its starting position. Automatic feeding and cutting are achieved through the coordinated operation of the traveling wheel structure and the slow-moving wheel.

[0032] The above method not only greatly increases cutting efficiency but also improves the safety of the cutting operation. During the cutting process, the steel cylinder is suspended in the air, and the elastic contact avoids friction between the steel cylinder and the material table. Attached Figure Description

[0043] Example 1

[0044] like Figure 1-5As shown, a treadmill roller pushing and cutting device includes a material platform 1. Several support structures for supporting roller blanks are installed on the top of the material platform 1. The support structures are arranged in segments. Specifically, each support structure includes brackets 61 fixedly installed on both sides of the top of the material platform 1, with rollers 6 rotatably connected between the brackets 61. In existing methods, to reduce friction between the rollers and the steel cylinder blanks 3, rubber sleeves are fitted onto the rollers 6 to achieve elastic support.

[0045] The aforementioned treadmill roller pushing and cutting device also includes an autonomous pushing mechanism 4, which pushes the steel cylinder blank 3. The pushing process can achieve long-distance pushing as well as short-distance pushing (short-distance pushing is used to correct the pushing length for accurate cutting).

[0046] Specifically, the autonomous pushing mechanism 4 includes an annular dragging bracket 41. Four circumferentially distributed slow-push structures 42 are installed on the inner wall of the annular dragging bracket 41. Each slow-push structure 42 includes a slow-push wheel bracket 421 (the push wheel bracket is bolted to the annular dragging bracket 41). A slow-push wheel 423, which frictionally pushes the steel cylinder billet 3, is rotatably connected to the slow-push wheel bracket 421. A slow-push wheel motor 422, which drives the slow-push wheel 423 to rotate, is installed on the slow-push wheel bracket 421 (a motor bracket is installed on the slow-push wheel motor 422, and the motor bracket is fixedly installed on the push wheel bracket). Specifically, similar to existing methods, the output shaft of the slow-push wheel motor 422 is fixedly installed on the slow-push wheel 423.

[0047] The use of a pusher wheel motor 422 to drive the pusher wheel 423 to rotate is a conventional motor-driven roller rotation structure disclosed in the prior art. Following the same structure as existing motor-driven rollers, the pusher wheel motor 422 is a motor capable of rotating in both directions.

[0048] During operation, the steel cylinder blank 3 passes through the four push rollers 423 (the push rollers 423 are made of rubber, and the outline of the push rollers 423 has several friction ridges 4231 integrally formed).

[0049] Therefore, when driven by the slow-pushing wheel motor 422, the four slow-pushing wheels 423 provide frictional power to the steel cylinder billet from the top, bottom and left and right sides, so as to slowly push the steel cylinder billet 3 forward (or slowly pull it backward). The purpose of this method is that when the steel cylinder billet 3 is pushed to a certain length by the cutting equipment (in the existing way, a cutting equipment is set at the front end of the material table 1, specifically a cutting machine), before the cutting machine's next wheel cuts, the slow-pushing wheel 423 structure will further slowly push or pull the cylinder until the length of the cut meets the requirements.

[0050] Because the pusher wheel 423 is made of rubber and has circumferentially distributed friction ridges 4231 (rubber material) on it, and with the cooperation of four pusher wheels 423, the steel cylinder blank 3 has a large frictional pushing force and high pushing stability.

[0051] Example 2

[0052] like Figure 1-5 As shown, based on the structure of Embodiment 1, the autonomous pushing mechanism 4 further includes a fast-pushing structure. This fast-pushing structure includes support arms 51 mounted on the left and right sides of the annular dragging bracket 41. The lower end of each support arm 51 is equipped with a traveling wheel structure, which rolls and pushes the device forward. Long-distance pushing is achieved through the traveling wheel structure. Specifically, after the steel cylinder blank 3 is cut, the traveling wheel structure continues to push the entire device forward for further cutting. Then, the traveling wheel structure returns to its starting position (at which point the operator assists in pushing the steel cylinder blank) or, under the action of the aforementioned slow-pushing wheel 423, continues to push the steel cylinder blank 3 forward a certain length. Subsequently, the traveling wheel structure continues to move forward until the steel cylinder extends below the cutting wheel of the cutting machine.

[0053] The above method enables automatic pushing of the steel cylinder billet.

[0054] Specifically, side rails 2 are fixedly connected to the left and right sides of the material platform 1, respectively; the traveling wheel structure rolls on the side rails 2. The traveling wheel structure includes a first horizontally arranged traveling roller 531, and a traveling roller motor 53 (the traveling roller motor 53 is fixedly mounted on the support arm 51) is installed on the support arm 51 to drive the traveling roller 531. Similarly, the structure and principle of the traveling roller motor 53 driving the traveling roller 531 are the same as the conventional motor-driven roller structure and principle disclosed in the prior art. Furthermore, similar to the existing motor-driven roller movement, the traveling roller motor 53 can drive the traveling roller 531 to travel a specific distance and then stop.

[0055] To ensure stability during travel, a limiting groove 21 is provided on the side wall of the aforementioned side track 2, and the traveling roller 531 is limited to rolling within the limiting groove 21.

[0056] Meanwhile, the walking wheel structure also includes a vertically arranged support roller 52, which supports the rolling on the top of the side track 2; similar to the existing structure, a roller shaft is rotatably connected to the support roller 52, and the roller shaft is fixedly installed on the support arm 51.

[0057] During operation, the steel cylinder blank is moved over a wide range under the drive of the walking roller motor 53.

[0058] Example 3

[0059] like Figure 1-5As shown, this embodiment, based on the structure of embodiment 2, installs sensors at both ends of the side track 2 in a conventional manner. When the walking wheel structure moves to the sensor at the front position, the sensor detects the movement and the walking roller motor 53 stops. Similarly, when it moves to the sensor at the rear position (not shown in the figure), the walking roller motor 53 stops. The sensor-controlled motor operating position is a conventional technology disclosed in the prior art. Those skilled in the art can consult technical manuals and technical dictionaries for the specific control structure and control principle process.

[0060] In actual operation, the motor can also be started and stopped manually.

[0061] This method greatly improves production efficiency, and during the cutting process, the steel cylinder blank 3 is limited to the rear side between the four push rollers 423, so the cutting safety is high and the technical defect of the steel cylinder blank 3 splashing is not easy to occur during the cutting process.

[0062] Example 4

[0063] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 3, a roller blank guiding mechanism is installed on the top of the material platform 1. During the feeding process of the steel cylinder blank 3, it is guided by the steel cylinder blank 3 guiding mechanism. Correspondingly, the roller blank guiding mechanism includes a guide seat 71, on which a guide hole is opened, through which the steel cylinder blank 3 is guided; a cylinder pressing structure is installed on the top of the guide seat 71. The cylinder pressing structure includes a cylinder 72 (in the conventional way, the cylinder barrel of the cylinder 72 is fixedly installed on the top of the guide seat 71, and a through hole for sliding connection of the cylinder piston rod is opened on the top of the guide seat 71), and the piston rod of the cylinder 72 passes through the guide seat 71; during the cutting process, the roller blank is locked by the piston rod of the cylinder 72.

[0064] In the above manner, during the cutting process, near the cutting position point, the steel cylinder blank 3 is locked by the guide seat 71 and the cylinder.

[0065] Meanwhile, the limiting function of the guide seat 71 further increases the accuracy of pushing and the safety of cutting operations.

[0066] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
