Description

Technical Field

[0001] The present application relates to the technical field of belt cutting machine adjustment, and in particular to a belt cutting machine tightening device and tightening method. Background Art

[0002] In the related art, the belt slippage problem of the belt-type cutting machine often occurs in actual work, which will eventually lead to insufficient output power. One of the many reasons is that the four fixing bolts of the motor base of the cutting machine are slightly displaced, resulting in a reduction in the distance between the belt drive system and the motor base, which in turn causes the belt to loosen, resulting in insufficient cutting power.

[0003] In actual work, when manually adjusting the tightness of the belt, tools such as rulers are needed to accurately check the displacement. The work efficiency is very low, and it requires at least two people to operate at the same time and cooperate tacitly to complete the task. Summary of the Invention

[0007] The belt cutter tensioning device provided in this application includes a retaining member, a telescopic assembly, and a thrust plate. The belt cutter includes a drive assembly, a driven pulley, and a base. The drive assembly includes a motor, a driving pulley, and bolts for securing the motor. The motor's output shaft is coaxially fixedly connected to the driving pulley. The motor is bolted to the base, and the belt is tensioned between the driving pulley and the driven pulley.

[0008] When using this tensioning device to tighten the belt, the slot of the retaining member engages the base of the belt cutter, specifically the driven pulley mounting bracket on the base. The thrust plate abuts the bolts securing the motor. By controlling the extension of the telescopic assembly, the drive assembly can be directly pushed relative to the base, achieving rapid belt tensioning. Specifically, when the telescopic assembly extends, the thrust plate is pushed away from the retaining member, pushing the bolts and motor, which in turn drives the driving pulley to move synchronously, increasing the gap between it and the driven pulley, thereby achieving rapid belt tightening.

[0009] In combination with the first aspect, in some feasible embodiments, the telescopic assembly includes: a first screw and a second screw arranged axially in a collinear manner, the thread rotation directions of the first screw and the second screw being opposite; a tightening nut connected between the first screw and the second screw; rotating the tightening nut can cause the first screw and the second screw to produce reverse displacement.

[0016] In combination with the first aspect, in some feasible embodiments, the contact surface between the thrust plate and the drive assembly is provided with an elastic gasket or a polyurethane buffer layer for dispersing the abutting pressure.

[0017] A second aspect of the present application provides a belt cutter tightening method, comprising: embedding the belt cutter tightening device of any of the above technical solutions on the base of the belt cutter, so that the slot of the locking member is engaged with the base, and the thrust plate abuts against the drive assembly of the belt cutter;

[0018] Rotating the tightening nut causes the first threaded rod and the second threaded rod to move in opposite directions, driving the thrust plate to move away from the positioning member, thereby pushing the drive assembly to move relative to the base and tightening the belt of the belt cutting machine.

The tightening device only requires one person to easily complete the belt tightening. The adjustment process is precise and labor-saving, avoiding the tediousness and instability of traditional manual adjustment.

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0031] Refer to the following Figures 1 to 5 A belt cutter tightening device 100 and a belt cutter tightening method according to some embodiments of the present application are described.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the present application proposes a belt cutting machine tightening device 100, comprising: a locking member 110, the locking member 110 including a slot 112, the slot 112 being used to be locked to the base of the belt cutting machine; a telescopic assembly 120, one end of the telescopic assembly 120 being connected to the locking member 110; a thrust plate 130, connected to the other end of the telescopic assembly 120, the thrust plate 130 being used to abut against the driving assembly of the belt cutting machine; wherein, when the telescopic assembly 120 is extended, the thrust plate 130 is pushed to move in a direction away from the locking member 110, so as to push the driving assembly to move relative to the base, so as to tighten the belt of the belt cutting machine.

[0033] The belt cutter tensioning device 100 provided herein includes a retaining member 110, a telescopic assembly 120, and a thrust plate 130. The belt cutter includes a drive assembly, a driven pulley, and a base. The drive assembly includes a motor, a driving pulley, and bolts for securing the motor. The motor output shaft is coaxially fixedly connected to the driving pulley, which is bolted to the base. The belt is tensioned between the driving pulley and the driven pulley.

[0034] When the tightening device is used to tighten the belt, the slot 112 of the clamping member 110 is clamped on the base of the belt cutting machine, specifically on the driven wheel fixing frame on the base. The thrust plate 130 is in contact with the bolts used to fix the motor.

[0035] By controlling the extension of telescopic assembly 120, the drive assembly can be directly pushed to move relative to the base, achieving rapid belt tensioning. Specifically, when telescopic assembly 120 extends, thrust plate 130 is pushed away from retaining member 110, driving the bolt and motor to move, driving the driving pulley to move synchronously, increasing the gap between the driving pulley and the driven pulley, thereby achieving rapid belt tightening.

[0036] The belt cutting machine tightening device 100 provided in this application is compact and has a simple mechanical structure, requiring few parts. It is easy to operate and labor-saving. Previously, adjusting the slack in the belt required the coordinated efforts of at least two people. Specifically, after loosening the four bolts on the motor base, the bolts are forcibly moved, causing them to shift, thereby tightening the belt. Now, using this tightening device, only one person is required, and the adjustment process is precise and labor-saving, avoiding the tediousness and instability of traditional manual adjustment.

[0037] Previously, even if two people worked together, they might not be able to accurately and synchronously move the four bolts of the motor base to the same distance without error. This device can accurately solve this problem and improve the accuracy of adjusting the cutting machine belt displacement.

[0038] The tightening device provided in this application is primarily designed for applications where the spacing between components of a device requires fine-tuning. It can be used to adjust the tension of belts in belt-type cutting machines. It is also suitable for other applications where the spacing or gap between two components of a machine needs to be adjusted.

[0039] In practical applications, the tightening device can also be industrialized and mass-produced according to the actual needs of different mechanical equipment. For example, the size can be increased or decreased, and the material used can be changed to meet the requirements of different equipment and facilities.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments provided in the present application, optionally, the telescopic assembly 120 includes: a first screw 122 and a second screw 124 arranged axially in a colinear manner, and the thread rotation directions of the first screw 122 and the second screw 124 are opposite; a tightening nut 126, connected between the first screw 122 and the second screw 124; rotating the tightening nut 126 can cause the first screw 122 and the second screw 124 to produce reverse displacement.

[0041] In this embodiment, the telescopic assembly 120 includes a first screw rod 122, a second screw rod 124, and a locking nut 126. The locking nut 126 is located between the first screw rod 122 and the second screw rod 124 and is threadedly connected to the first screw rod 122 and the second screw rod 124. The threads of the first screw rod 122 and the second screw rod 124 rotate in opposite directions.

[0042] When tightening nut 126 is rotated, first screw 122 and second screw 124 move in opposite directions. The fine pitch of the threads allows for precise control of the displacement of thrust plate 130, ensuring accurate belt tension adjustment and preventing over-tightening or under-loosening. The threads themselves are inherently self-locking, maintaining thrust plate 130 in place after adjustment without the need for additional locking devices, facilitating subsequent motor mounting.

[0043] The present application directly converts rotational motion into linear extension and contraction through the co-linear arrangement of twin screws and a pushing nut 126. The structure is compact and the force transmission path is short. During operation, a large thrust can be generated by simply rotating the nut, which is labor-saving and efficient.

[0044] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments provided in the present application, optionally, the belt cutting machine tightening device 100 further includes: a first displacement skeleton 128, the first end of the first displacement skeleton 128 is threadedly connected to the first screw 122, and the second end of the first displacement skeleton 128 is fixedly connected to the locking member 110; a second displacement skeleton 129, the first end of the second displacement skeleton 129 is threadedly connected to the second screw 124, and the second end of the second displacement skeleton 129 is fixedly connected to the thrust plate 130.

[0045] In this embodiment, the belt cutter tightening device 100 further includes a first displacement frame 128 and a second displacement frame 129. These displacement frames and the screw form a composite transmission structure. By adding the first and second displacement frames 128 and 129, the bending and lateral load resistance are significantly improved, preventing screw deformation or deflection under high loads and ensuring linear and stable thrust transmission.

[0046] The screw only bears axial thrust, and the lateral force is borne by the displacement skeleton, which can reduce abnormal wear of the thread surface and extend the life of the screw.

[0047] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments provided in the present application, optionally, the second ends of the first displacement skeleton 128 and the second displacement skeleton 129 are Y-shaped opening structures.

[0048] In this embodiment, the Y-shaped opening structure is fixedly connected to the locking member 110 and the thrust plate 130 to form a triangular force distribution. Compared with a single-point connection, the anti-torsion and anti-eccentric load capabilities are significantly improved, preventing the frame from loosening or deformation under high load.

[0049] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments provided in the present application, optionally, a sleeve hole 132 is provided on the thrust plate 130 .

[0050] In this embodiment, a sleeve hole 132 is provided on the thrust plate 130, and the thrust plate 130 is sleeved on the bolt through the sleeve hole 132, which facilitates the rapid and accurate positioning of the belt cutting machine tightening device 100, simplifies the adjustment operation, and can improve the tightening efficiency of the belt.

[0051] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments provided in the present application, optionally, an opening hole 134 is further provided on the thrust plate 130 .

[0052] In this embodiment, the thrust plate 130 is further provided with an opening 134, through which the thrust plate 130 is fitted onto the bolt. By providing the opening 134 on the thrust plate 130, the thrust plate 130 can be directly fitted onto the bolt by sliding sideways, thereby achieving rapid and precise positioning of the belt cutter tightening device 100, simplifying the adjustment operation, and improving the efficiency of belt tightening.

[0053] In some embodiments provided in the present application, optionally, the belt cutting machine tightening device 100 further includes: a wear-resistant bushing provided on the inner surfaces of the sleeve hole 132 and the opening hole 134 .

[0054] In this embodiment, the wear-resistant bushing is typically made of a high-strength, wear-resistant material (such as alloy steel, engineering plastic, or ceramic composite material). Providing the wear-resistant bushing on the inner surfaces of the sleeve hole 132 and the opening hole 134 effectively reduces direct friction between the sleeve hole 132 and the opening hole 134 and the bolt, reducing wear and extending the service life of the tightening device.

[0055] In some embodiments provided in the present application, optionally, the belt cutting machine tightening device 100 further includes: an anti-slip layer, which is arranged in the slot 112, and the surface of the anti-slip layer is provided with anti-slip lines to prevent slipping during the tightening process.

[0056] In this embodiment, the belt cutter tightening device 100 further includes an anti-skid layer. The anti-skid layer, through its anti-skid properties and surface texture, increases the coefficient of friction between the slot 112 and the cutter base, preventing the tightening device from slipping due to vibration, impact, or external forces during the tightening process.

[0057] The anti-slip pattern reduces the risk of slippage due to lubricating oil, dust, or ambient humidity through mechanical engagement. The anti-slip layer disperses the localized pressure of the tightening component on the slot 112, preventing wear caused by direct contact and extending the service life of the slot 112 and the tightening component.

[0058] In some embodiments provided in the present application, optionally, the contact surface between the thrust plate 130 and the driving assembly is provided with an elastic gasket or a polyurethane buffer layer for dispersing the abutting pressure.

[0059] In this embodiment, an elastic gasket (such as rubber or silicone) or polyurethane buffer layer elastically deforms to evenly distribute the concentrated pressure on the contact surface over a larger area, preventing direct contact between the thrust plate 130 and the bolt. This significantly reduces the peak pressure on the contact surface, reducing the risk of metal fatigue and plastic deformation. This extends the service life of the thrust plate 130 and the drive assembly, and reduces the loss of accuracy due to wear. The elastic deformation of the buffer layer can compensate for any flatness deviation or installation gap between the thrust plate 130 and the drive assembly.

[0060] The second aspect of the present application proposes a belt cutter tightening method, comprising: embedding the belt cutter tightening device in any of the above embodiments on the base of the belt cutter, so that the slot of the clamping member is clamped on the base, and the thrust plate abuts against the drive assembly of the belt cutter; rotating the tightening nut so that the first threaded rod and the second threaded rod move in opposite directions, driving the thrust plate to move in a direction away from the clamping member, so as to push the drive assembly to move relative to the base, thereby tightening the belt of the belt cutter.

[0061] The belt cutting machine tightening method provided in this application uses the reverse thread design of the first threaded rod and the second threaded rod. When the tightening nut rotates, the two rods move synchronously in opposite directions, ensuring that the thrust plate pushes the drive assembly in a linear and stable manner to tighten the belt of the belt cutting machine.

[0062] In actual applications, the four fixing bolts of the cutting machine's motor base are slightly displaced, which causes the distance between the belt transmission system and the motor base to decrease, resulting in belt loosening, and the final result is insufficient cutting power.

[0063] If slipping occurs, the general solutions are as follows:

[0064] 1) First use a wrench to manually loosen the four bolts on the motor base.

[0065] 2) Use manpower to push the motor backward, and the bolt displacement position can achieve the good effect of tightening the cutting machine belt.

[0066] 3) Then fine-tune the four bolts as a whole to maintain the consistency of the relative displacement of the bolts to prevent the belt from slightly deviation.

[0067] 5) Finally, tighten all four bolts into place and prevent them from moving, thus achieving the ultimate goal of tightening the belt.

[0068] Conventional solutions are, firstly, cumbersome and require tools like rulers to accurately verify displacement, resulting in low efficiency. Secondly, they are laborious, requiring at least two people to operate simultaneously and in close coordination. Thirdly, even the slightest inappropriate adjustment can lead to unstable belt operation, affecting the efficiency of the cutting machine, further shortening its lifespan and even compromising operational safety.

[0069] To solve this problem, the present application provides a belt cutting machine tightening device 100, including: a thrust plate 130, a locking member 110, a first screw 122, a second screw 124, a tightening nut 126, a Y-shaped displacement frame, a sleeve hole 132 and an opening hole 134.

[0070] The thrust plate 130 is made of galvanized steel plate, has a length × width = 150 × 50 mm, and a thickness of 5 mm. When in use, it is used to "hold up" the bolt base of the cutting machine motor.

[0071] The clamping member 110 is made of stainless steel and has a rectangular "cage 112" structure with one open side and three closed sides. It is 80mm long and has an end surface of 10×10mm. When in use, it is used to "clamp" the fixed frame of the driven pulley of the cutting machine belt.

[0072] The first screw rod 122 and the second screw rod 124 are M16 threaded rods with a length of 160 mm. The first screw rod 122 can be a left-handed threaded rod, and the second screw rod 124 can be a right-handed threaded rod.

[0073] The thread rotation directions of the first screw rod 122 and the second screw rod 124 must be opposite. In this way, when the tightening nut 126 is rotated, the thrust plate 130 and the retaining member 110 will be displaced in opposite directions, thereby achieving the purpose of tightening the belt.

[0074] Tightening nut 126, an M16 nut, matches the size of first screw 122 and second screw 124. When using this tightening device, once the device is fully "seated" in the desired position, rotating nut 126 with a wrench causes the thrust plate 130 and retaining member 110 to simultaneously "reverse displacement," further "driving" the fixing bolts of the motor base to move within the rectangular hole. This, in turn, causes the driving pulley of the cutting machine's belt to shift, further tightening the belt and achieving the desired tightening effect. Tightening nut 126 is the core design element of this device.

[0075] The Y-shaped displacement skeleton is made of galvanized stainless steel, with an "opening" size of 50 mm and a length of about 80 mm. By rotating the first displacement skeleton 128 and the second displacement skeleton 129, the slot 112 of the positioning member 110 and the thrust plate 130 will be displaced along the screw respectively. Furthermore, the entire device can be easily "embedded" into the appropriate position that needs to be adjusted on the cutting machine. When it starts to be used and the tightening nut 126 is rotated, the first displacement skeleton 128 and the second displacement skeleton 129 will no longer move. In other words, when the device is "embedded" into the predetermined position, the first displacement skeleton 128 and the second displacement skeleton 129 stop displacing.

[0076] The purpose of providing the sleeve hole 132 and the opening hole 134 on the thrust plate 130 is to better and more quickly "embed" the device in a suitable position.

[0077] In a specific embodiment, the first installation method is as follows: the thrust plate 130 and the retaining member 110 of the tightening device are respectively "engaged" on the base of the driving wheel shaft of the cutting machine's belt motor and "engaged" on the fixed frame of the driven wheel shaft of the cutting machine. By using a wrench, the tightening nut 126 is rotated, which drives the first screw 122 and the second screw 124 to rotate, further driving the thrust plate 130 and the retaining member 110 to displace, further causing the four bolts on the base of the cutting machine's motor to displace, further driving the driving wheel shaft of the cutting machine's motor to displace, and further tightening the cutting machine's belt, achieving the ultimate goal.

[0078] The second installation method is to insert the sleeve hole 132 and the opening hole 134 on the thrust plate 130 into the two front bolts on the motor base of the cutting machine (after all four bolts are loosened). Then, use a wrench to turn the tightening nut 126, further causing the thrust plate 130 and the retaining member 110 to move, further causing the bolts on the motor base to move, and further achieving the purpose of tightening the belt. When using this device, the opening hole 134 is first inserted into one of the front bolts on the motor base. After fine-tuning the position according to the actual position, the round hole of the device can be easily inserted into the other bolt on the motor base. The purpose is to quickly install the device in the predetermined position. Generally speaking, the function of these two holes is another method and method of tightening the belt of this device.

[0079] like Figure 4 As shown, the tightening nut 126, the first screw 122 and the second screw 124 are partially welded into a whole. When the device is embedded in the predetermined position, it is only necessary to rotate the tightening nut 126 with a wrench to cause the thrust plate 130 and the retaining member 110 to move in opposite directions, thereby pushing the bolts of the motor base to move, and further causing the driving pulley shaft of the belt to move, ultimately achieving the purpose of tightening the cutting machine belt.

[0080] like Figure 5 As shown, the Y-shaped displacement frame utilizes the "open claw" components of a turnbuckle bolt, paired with corresponding threaded rods and nuts. Its primary function is to rotate the first displacement frame 128, causing displacement along the threaded rod, further displacing the retaining member 110 and thrust plate 130 to reach a predetermined position, ultimately "embedding" the entire device into the desired position. The first and second displacement frames 128, 129, are welded to the thrust plate 130 and retaining member 110, respectively, to form a single unit.

[0081] The rotation of the push nut 126 can also be realized by adding a small motor and a matching switch, so as to realize electric automation and replace the adjustable spanner as the original power.

[0082] Industrial mass production can be achieved by changing the size of the device and the materials of its components. For example, the size can be increased or decreased, and further, the processing material of the device can be changed to meet the needs of different equipment and facilities.

[0083] The device can be widely used to solve the technical problem of adjusting the tightness of belts in belt cutting machines. It is also suitable for other mechanical equipment that needs to adjust the distance or gap between two parts (provided that there is a spacing fine-tuning stroke between the parts of the equipment itself).

[0084] In this application, the term "plurality" refers to two or more, unless otherwise specified. Terms such as "installed," "connected," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean fixed, removable, or integrally connected; and "connected" can mean directly or indirectly through an intermediary.
