Description

Technical Field

[0001] This utility model relates to the technical field of button attaching machines, and in particular to a button attaching machine limiting structure. Background Technology

[0002] Conveyor belts, also known as transport belts, are products used in belt conveyors to carry and transport materials. They are suitable for continuous, high-efficiency, and steep-angle transport, and are therefore widely used in applications with short conveying distances and small conveying capacities. To achieve their intended purpose, all conveyor belts must be joined in a loop. Common methods for splicing conveyor belts include cold bonding, hot vulcanization, and mechanical splicing. Mechanical splicing is the most frequently used method for conveyor belts; it is simple, convenient, and economical.

[0003] The conveyor belt consists of a bottom plate, a top plate, a connecting plate, and U-shaped fasteners. The bottom plate, top plate, and connecting plate form a U-shaped structure, and the U-shaped fasteners are inserted into the top plate from the outside of the bottom plate. The machining equipment that uses these fasteners to connect the two sections of the conveyor belt is called a fastener attaching machine.

[0004] In button-attaching machines, limiting the slider's vertical movement is necessary to ensure its stability. Our existing limiting structure requires installing guide bars in mounting slots on the limiting components. The two guide bars are positioned opposite each other and then slide onto a guide rail (the guide bars have grooves for sliding onto the guide rail). This process is difficult and requires additional installation of the guide bars. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a button fastening machine limiting structure.

[0006] This utility model provides a button fastening machine limiting structure, installed on a guide rail 6, including two back-to-back limiting members 1 and 2. The right limiting member 2 has a clearance hole 3 at its right end. The left limiting member 1 and the right limiting member 2 are spaced apart and have the same structure except for the clearance hole 3. The left limiting member 1 includes a vertical block 1.1, a longitudinal block 1.2 and a locking block 4. The locking block 4 is symmetrically arranged on the front and rear sides of the vertical block 1.1. The end of the locking block 4 has a second screw hole 5. The longitudinal block 1.2 is slidably fitted onto the guide rail 6.

[0007] Furthermore, the longitudinal block 1.2 is longitudinally disposed at the top of the vertical block 1.1, and the longitudinal block 1.2 extends out of the front and rear sides of the vertical block 1.1.

[0008] Furthermore, the left and right end faces of the longitudinal block 1.2 are flush with the left and right end faces of the vertical block 1.1, respectively.

[0009] Furthermore, a groove 1.3 is longitudinally provided on the side of the longitudinal block 1.2 away from the right limiting member 2, and guide bars that slide in the groove 1.3 are symmetrically provided on the left and right sides of the inner wall of the guide rail 6.

[0010] Furthermore, the locking blocks 4, located on one side of the left limiting member 1, are arranged at equal intervals along the height direction of the vertical block 1.1.

[0011] Furthermore, the clearance holes 3 are two symmetrical holes arranged in a long strip along the height direction of the right limiting member 2.

[0012] Furthermore, the guide rail 6 is formed by cold drawing.

[0013] The advantages of this utility model are: no guide strip is required and processing is convenient, reducing production costs; the extended longitudinal block increases the sliding contact surface of the guide rail, making the sliding more stable and reliable; the two limiting members allow the slider between the two to move up and down and slide along the guide rail, and the vertical and longitudinal blocks have good strength; the flush end faces of the longitudinal and vertical blocks facilitate processing and save costs; the sliding grooves on the limiting members are arranged opposite to each other to adapt to the width of the guide rail; the two elongated clearance holes are for the connecting parts to pass through the clearance holes and provide the connecting parts with room to move; cold drawing can improve the dimensional accuracy and surface quality of the guide rail and improve its mechanical properties.

[0017] Figure 4 This is a schematic diagram of the structure of this utility model installed on the guide rail. Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] See Figures 1 to 4This utility model provides a button fastener limiting structure, installed on a guide rail 6, which includes two oppositely arranged left limiting members 1 and right limiting members 2. The right end of the right limiting member 2 is provided with a clearance hole 3. The left limiting member 1 and the right limiting member 2 are spaced apart and have the same structure except for the clearance hole 3. The left limiting member 1 includes a vertical block 1.1, a longitudinal block 1.2 and a locking block 4. The longitudinal block 1.2 is longitudinally arranged at the top of the vertical block 1.1 and extends out of the front and rear sides of the vertical block 1.1. The extension of the longitudinal block can increase the sliding contact surface of the guide rail, making the sliding more stable and reliable. The locking block 4 is symmetrically arranged on the front and rear sides of the vertical block 1.1. The end of the locking block 4 is provided with a second screw hole 5. The longitudinal block 1.2 is slidably fitted onto the guide rail 6. The previous limiting structure required the installation of guide bars in the mounting slots of the limiting components, and then the components would slide onto the guide rails via the guide bars. The two limiting components have been improved upon this. The two limiting components allow the sliders between the two components to move up and down (blocked by the housing at the front and back) and slide along the guide rails. Moreover, the vertical and longitudinal blocks have good strength, eliminating the need for guide bars and reducing the production cost of the limiting components.

[0021] The left and right end faces of the longitudinal block 1.2 are flush with the left and right end faces of the vertical block 1.1, respectively. Having the end faces of the longitudinal and vertical blocks flush facilitates machining and saves costs.

[0022] See Figure 1 , Figure 4 The longitudinal block 1.2 has a longitudinal groove 1.3 on the side away from the right limiting member 2. Guide bars that slide in the groove 1.3 are symmetrically arranged on the left and right sides of the inner wall of the guide rail 6. The guide bars have grooves, which are arranged opposite to each other. The grooves on the limiting member are arranged opposite to each other to accommodate the width of the guide rail.

[0023] The locking blocks 4, located on one side of the left limiting member 1, are arranged at equal intervals along the height direction of the vertical block 1.1. There are three locking blocks on one side, distributed evenly at the top, middle, and bottom of the vertical block, which can be well locked onto the housing of the fastening machine, thus limiting the limiting member to the housing, resulting in a stable and reliable structure.

[0024] The clearance holes 3 are two symmetrical holes arranged in a long strip along the height direction of the right limiting member 2. The two long clearance holes are designed to allow the connecting member to pass through and provide the connecting member with room to move.

[0025] Guide rail 6 is formed by cold drawing. Cold drawing can improve the dimensional accuracy and surface quality of the guide rail, and improve its mechanical properties.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
