A roving frame belt displacement control device

Abstract

This utility model relates to the technical field of roving frame accessories, specifically to a belt displacement control device for a roving frame. It features a self-propelled mechanism that drives a sliding pusher block to move, thereby pushing the belt. Since the belt's stress point is at the connection between the belt and the upper or lower bobbin, and the sliding pusher block moves along the upper or lower bobbin and pushes the belt from the stress point, the belt will not bend, ensuring precise control of the belt displacement. The self-propelled mechanism drives a friction wheel to roll on a displacement crossbar via a transverse motor, thereby automatically moving the drive connector and the sliding pusher block. The sliding pusher block is connected to a fixed cylinder via a telescopic rod, allowing it to automatically extend and retract as it moves along the outer surface of the upper or lower bobbin, ensuring that the sliding pusher block always remains in contact with the outer surface of the upper or lower bobbin.

Description

Technical Field

[0001] This utility model relates to the technical field of roving frame accessories, and in particular to a roving frame belt displacement control device. Background Technology

[0002] A roving frame is a spinning machine that produces roving from fiber slivers. Its main functions are drafting and twisting, and winding the roving into a specific package to meet the processing requirements of a ring spinning frame. The bobbin belt in the roving frame is a key transmission belt installed in the bobbin (cone wheel) drive mechanism. Its displacement on the conical bobbin adjusts the winding speed of the bobbin, achieving dynamic balance control of yarn tension.

[0003] When the belt moves in the conical cannon, the displacement is generally controlled by some power components pushing and pulling the belt. When the power components pull the belt, the contact position with the belt is generally located between the upper and lower cannons. There is enough space between the upper and lower cannons and there are no obstructions.

[0004] However, because the belt is flexible and there is considerable friction at the connection between the belt and the upper and lower cannons, pushing or pulling the belt from the middle position can easily cause it to bend. Although bending can eventually force the belt to shift on the upper and lower cannons, it is difficult to precisely control the amount of shift. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a belt displacement control device for a roving frame, so as to solve the technical problem that it is difficult to accurately control the displacement of the belt on the upper and lower roving frames when driving the belt displacement in the prior art.

[0006] To achieve the above objectives, this utility model provides a belt displacement control device for a roving frame, including a bracket for mounting an upper and lower bobbin, wherein the upper and lower bobbins jointly support the belt, and the belt displacement control device further includes:

[0007] The displacement crossbars are fixedly connected to the upper and lower sides of the bracket, and the self-propelled mechanism is movably connected to the displacement crossbars;

[0008] A sliding push block is provided inside the self-propelled mechanism. An automatic telescopic component is provided between the sliding push block and the self-propelled mechanism. The sliding push blocks on both sides of the bracket are slidably connected to the upper and lower cannons, respectively.

[0009] Furthermore, the bracket is provided with two displacement crossbars on its upper and lower sides, and the self-propelled mechanism is slidably connected to the two displacement crossbars at the same time.

[0010] Furthermore, two sets of self-propelled mechanisms are provided on the upper and lower displacement crossbars of the bracket, and the two sets of self-propelled mechanisms are located on the left and right sides of the belt, respectively.

[0011] Furthermore, connecting seats are fixedly connected to the upper and lower sides of the bracket, and the displacement crossbar is fixedly connected to the bracket through the connecting seats.

[0012] Furthermore, the self-propelled mechanism includes a connector slidably connected to the displacement crossbar, a motor housing fixedly connected to the connector, and a transverse motor installed in the motor housing for driving the connector to move on the displacement crossbar.

[0013] Furthermore, a friction wheel is fixedly connected to the output shaft of the transverse motor. The friction wheel is in rolling connection with the connecting member, and the friction wheel is also rotatably connected inside the connecting member.

[0014] Furthermore, the automatic telescopic component includes a fixed cylinder fixedly connected to the connector, the fixed cylinder passing through the connector, and a telescopic rod slidably connected inside the fixed cylinder, and the sliding push block fixedly connected to the outer end of the telescopic rod.

[0015] Furthermore, a compression spring is also provided inside the fixed cylinder, with its two ends connected to the inner end of the telescopic rod and the bottom of the groove inside the fixed cylinder, respectively.

[0016] The beneficial effects of this utility model are as follows: 1. The self-propelled mechanism drives the sliding push block to move, which in turn pushes the belt to move. Since the force point of the belt is at the connection position between the belt and the upper or lower cannon, and the sliding push block moves along the upper or lower cannon and pushes the belt from the force point position, the belt will not bend, thus ensuring the accuracy of belt displacement control.

[0017] 2. The self-propelled mechanism drives the friction wheel to roll on the displacement crossbar through the transverse motor, thereby realizing the automatic movement of the drive connector and the sliding push block. The sliding push block is connected to the fixed cylinder through the telescopic rod. Therefore, the sliding push block can automatically extend and retract as it moves along the outer surface of the upper or lower cannon, ensuring that the sliding push block always sticks to the outer surface of the upper or lower cannon.

[0018] 3. The self-propelled mechanism, automatic telescopic component, and sliding pusher are arranged in four sets, located on the upper and lower sides, and the left and right sides respectively. When the belt needs to move to the left, the two sets on the right are driven to work, and when the belt needs to move to the right, the two sets on the left are driven to work. The two sets work together to accurately push the belt to the required displacement. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, because the belt 104 is flexible and there is considerable friction at the connection between the belt 104 and the upper and lower cannons 102 and 103, pushing or pulling the belt 104 from the middle position easily causes it to bend. Although bending eventually forces the belt 104 to shift on the upper and lower cannons 102 and 103, the amount of displacement is difficult to control precisely. Therefore, to solve this problem, this invention designs a bracket 101 for mounting the upper and lower cannons 102 and 103, with the upper and lower cannons 102 and 103 jointly supporting the belt 104.

[0029] The key feature is that displacement crossbars 106 are fixedly connected to the upper and lower sides of the support 101, and a self-propelled mechanism 107 is movably connected to the displacement crossbars 106. A sliding push block 115 is provided inside the self-propelled mechanism 107, and an automatic telescopic component is provided between the sliding push block 115 and the self-propelled mechanism 107. The sliding push blocks 115 on both sides of the support 101 are slidably connected to the upper iron cannon 102 and the lower iron cannon 103, respectively.

[0030] The self-propelled mechanism 107 drives the sliding pusher 115 to move, which in turn pushes the belt 104 to move. Since the force point of the belt 104 is at the connection position between the belt 104 and the upper iron cannon 102 or the lower iron cannon 103, and the sliding pusher 115 moves along the upper iron cannon 102 or the lower iron cannon 103 and pushes the belt 104 from the force point of the belt 104, the belt 01 will not bend, thus ensuring the accuracy of the displacement control of the belt 01.

[0031] The bracket 101 has two displacement crossbars 106 on its upper and lower sides, and the self-propelled mechanism 107 is slidably connected to the two displacement crossbars 106. The self-propelled mechanism 107 is connected to the two displacement crossbars 106 to ensure the stability of the self-propelled mechanism 107 and prevent the self-propelled mechanism 107 from rotating on the displacement crossbars 106.

[0032] In addition, two sets of self-propelled mechanisms 107 are provided on the upper and lower displacement crossbars 106 of the bracket 101, and the two sets of self-propelled mechanisms 107 are located on the left and right sides of the belt 104, respectively. Connecting seats 105 are fixedly connected to the upper and lower sides of the bracket 101, and the displacement crossbars 106 are fixedly connected to the bracket 101 through the connecting seats 105.

[0033] The self-propelled mechanism 107, the automatic telescopic component, and the sliding pusher 115 are arranged in four sets, located on the upper and lower sides and the left and right sides respectively. When the belt 104 needs to move to the left, the two sets on the right are driven to work, and when the belt 104 needs to move to the right, the two sets on the left are driven to work. The two sets work together to accurately push the belt 104 to the required displacement.

[0034] The second aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, in order to ensure that the sliding pusher 115 can always stick to the outer surface of the upper cannon 102 or the lower cannon 103 when it pushes the belt 104 to move, an automatic telescopic component is provided between the sliding pusher 115 and the self-propelled mechanism 107.

[0035] Specifically, the self-propelled mechanism 107 includes a connector 108 slidably connected to the displacement crossbar 106. A motor housing 109 is fixedly connected to the connector 108, and a transverse motor 110 is disposed within the motor housing 109 for driving the connector 108 to move on the displacement crossbar 106. A friction wheel 111 is fixedly connected to the output shaft of the transverse motor 110. The friction wheel 111 is in rolling connection with the connector 108, and the friction wheel 111 is also rotatably connected within the connector 108.

[0036] The automatic telescopic assembly includes a fixed cylinder 112 fixedly connected to the connector 108, the fixed cylinder 112 passing through the connector 108, and a telescopic rod 113 slidably connected inside the fixed cylinder 112. The sliding push block 115 is fixedly connected to the outer end of the telescopic rod 113. A compression spring 114 is also provided inside the fixed cylinder 112, with its two ends connected to the inner end of the telescopic rod 113 and the bottom of the groove inside the fixed cylinder 112, respectively.

[0037] The self-propelled mechanism 107 drives the friction wheel 111 to roll on the displacement crossbar 106 via the transverse motor 110, thereby enabling the automatic movement of the drive connector 108 and the sliding push block 115. The sliding push block 115 is connected to the fixed cylinder 112 via the telescopic rod 113. Therefore, the sliding push block 115 can automatically extend and retract as it moves along the outer surface of the upper cannon 102 or the lower cannon 103, ensuring that the sliding push block 115 always stays in contact with the outer surface of the upper cannon 102 or the lower cannon 103.

[0038] In summary, this utility model provides a self-propelled mechanism 107 to drive the sliding push block 115 to move, which in turn pushes the belt 104 to move. Since the force point of the belt 104 is at the connection position between the belt 104 and the upper iron cannon 102 or the lower iron cannon 103, and the sliding push block 115 moves along the upper iron cannon 102 or the lower iron cannon 103 and pushes the belt 104 from the force point of the belt 104, the belt 01 will not bend, thus ensuring the accuracy of the displacement control of the belt 01.
