Description

Technical Field

[0001] This utility model relates to the field of saw blade manufacturing technology, specifically to a shrinking machine for saw blade manufacturing with a precision positioning structure. Background Technology

[0002] In the saw blade production process, the heat shrink machine is a key packaging equipment before leaving the factory. It mainly uses heat to tightly wrap the saw blade with special shrink film, which can effectively isolate moisture and dust in the air, prevent the saw blade from getting damp and rusting or getting impurities on the surface, and protect the sharp teeth from being scratched by collisions. At the same time, the neat packaging shape also facilitates subsequent warehousing, stacking and long-distance transportation, reducing product damage in the logistics process.

[0003] Some existing devices lack a saw blade positioning structure, which can easily cause the saw blade to shift during transport to the heating zone. After entering the heating zone, the saw blade tends to deviate to one side of the heating chamber, resulting in localized tightness or looseness of the film material after heating. Furthermore, the position of the heating chamber in most devices is fixed. When dealing with multiple stacked thick saw blades, insufficient heating chamber height can cause the top film material to be too far from the heating tube, resulting in insufficient heating and incomplete shrinkage. For single thin saw blades, the excessively large chamber space leads to slow heating and easy heat loss, resulting in energy waste. Therefore, this utility model provides a saw blade shrinking machine with a precise positioning structure to solve the above problems. Utility Model Content

Each set of positioning structures includes a bearing, a connecting plate, a fixing plate, a positioning roller and a pointer. The two sets of bearings are respectively fixedly connected to both sides of the outer surface of one end of the heating chamber. A heat-shrinkable structure is provided inside the heating chamber. The heat-shrinkable structure includes a heating cavity, a slide, a top heating tube, and a side heating tube. Two sets of slide and side heating tubes are provided. The upper surface of the heating cavity is fixedly connected to the lower end of the push rod inside the cylinder.

[0011] For example, in a saw blade production shrinking machine with a precise positioning structure provided in at least one embodiment of the present invention, the pointer is fixedly connected to the surface of one side of the connecting plate, and the positions of the two sets of pointers correspond to the positions of the scale lines.

[0012] For example, in at least one embodiment of the present invention, a shrinking machine for saw blade production with a precise positioning structure is provided, which further includes: a limiting plate fixedly connected to the upper surface of the fixed plate, and the limiting plate being slidably sleeved on the outer surface of the limiting rod at the middle position.

[0021] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0026] like Figures 1 to 6 As shown, this utility model provides a saw blade production shrinking machine with a precise positioning structure, including: a main structure 1, the main structure 1 including a conveying device 11, a heating chamber 12, a cylinder 13, a T-shaped slide rail 14, a scale line 15, a servo motor 16, a bidirectional lead screw 17 and a limiting rod 18, and the T-shaped slide rail 14 is provided with two sets. Positioning structure 2, there are two sets of positioning structures 2, and the two sets of positioning structures 2 are symmetrically arranged left and right along the width direction of the conveying device 11. Each set of positioning structures 2 includes a bearing 21, a connecting plate 22, a fixing plate 23, a positioning roller 25 and a pointer 26. The two sets of bearings 21 are respectively fixedly connected to both sides of the outer surface of one end of the heating chamber 12. The heat shrink structure 3 is located inside the heating chamber 12. The heat shrink structure 3 includes a heating cavity 31, a slide 32, a top heating pipe 33 and a side heating pipe 34. The slide 32 and the side heating pipe 34 are provided in two sets. The upper surface of the heating cavity 31 is fixedly connected to the lower end of the push rod inside the cylinder 13.

[0027] The heating chamber 12 is fixedly connected to the surfaces on both sides of the conveying device 11, and the cylinder 13 is installed on the upper surface of the heating chamber 12. The push rod inside the cylinder 13 is slidably inserted into the interior of the upper surface of the conveying device 11.

[0028] The heating chamber 12 can isolate external dust and impurities, preventing impurities from entering the heating chamber 12 and affecting the heat shrinkage process during saw blade packaging, thus improving the stability of the saw blade packaging process.

[0029] Two sets of T-shaped slide rails 14 are fixedly connected to the inner walls on both sides of the heating chamber 12. The two sets of T-shaped slide rails 14 are symmetrically arranged left and right along the width direction of the conveying device 11. The servo motor 16 is installed on one side of the outer surface of one end of the heating chamber 12. One end of the bidirectional lead screw 17 is fixedly connected to the output shaft of the servo motor 16. The two ends of the bidirectional lead screw 17 are respectively connected to the inside of the two sets of bearing seats 21.

[0030] By starting the servo motor 16, the bidirectional lead screw 17 can be driven to rotate. The two sets of bearings 21 can limit the bidirectional lead screw 17, which can improve the stability of the bidirectional lead screw 17 during rotation and prevent the bidirectional lead screw 17 from shaking or moving during rotation.

[0031] Two sets of connecting plates 22 are threaded to both ends of the outer surface of the bidirectional lead screw 17, the scale line 15 is set on the outer surface of the front end of the heating chamber 12, and the limiting rod 18 is fixedly connected to the upper surface of the conveying device 11.

[0032] The rotation of the bidirectional lead screw 17 can drive the two sets of connecting plates 22 to move in opposite directions, thereby adjusting the distance between the two sets of connecting plates 22.

[0033] The fixing plate 23 is fixedly connected to the lower end of the connecting plate 22, and a positioning plate 24 is fixedly connected to one side surface of the fixing plate 23. The positioning roller 25 is rotatably connected to the inside of the positioning plate 24.

[0034] The movement of the two sets of connecting plates 22 can drive the two sets of fixed plates 23, positioning plates 24 and positioning rollers 25 to move synchronously. The two sets of positioning rollers 25 can restrict the position of the saw blade before it enters the heating chamber 12, and can play a positioning role when the saw blade enters the heating chamber 12, so that the saw blade can be kept in the center position inside the heating chamber 12 after it enters the heating chamber 12.

[0035] The pointer 26 is fixedly connected to the surface of one side of the connecting plate 22, and the positions of the two sets of pointers 26 correspond to the positions of the scale lines 15.

[0036] The movement of the two sets of connecting plates 22 can drive the two sets of pointers 26 to move synchronously. When the two sets of pointers 26 are moving, the operator can judge the distance between the two sets of positioning rollers 25 by observing the scale line 15, thereby improving the accuracy of adjustment.

[0037] Among them, the upper surface of the fixing plate 23 is fixedly connected to the limiting plate 27, and the limiting plate 27 is slidably sleeved on the outer surface of the middle position of the limiting rod 18.

[0038] The movement range of the two sets of limiting plates 27 can be limited by the setting of the limiting rod 18, which can prevent the two sets of limiting plates 27 from shaking when moving. This ensures that the positioning structure 2 can only move along the length direction of the limiting rod 18, which can prevent the positioning structure 2 from shaking or shifting when moving due to vibration, thereby improving the stability of the positioning structure 2 when limiting the saw blade.

[0039] Among them, the two sets of slide blocks 32 are fixedly connected to the outer surfaces of the heating chamber 31 on both sides, and the two sets of slide blocks 32 are slidably sleeved on the outer surfaces of the two sets of T-shaped slide rails 14.

[0040] By sliding between the two sets of slide blocks 32 and the two sets of T-shaped slide rails 14, the range of movement of the two sets of slide blocks 32 can be limited, which can prevent the two sets of slide blocks 32 from shaking when moving. This allows the heat shrink structure 3 to move only along the height direction of the two sets of T-shaped slide rails 14, which can prevent the heat shrink structure 3 from shaking or shifting when moving, thereby improving the stability of the heat shrink structure 3 when adjusting its height.

[0041] The top heating tube 33 is installed on the upper surface inside the heating cavity 31, and the two sets of side heating tubes 34 are respectively installed on the inner walls of the two sides of the heating cavity 31.

[0042] The top heating tube 33 can heat the upper surface of the film material, and the two sets of side heating tubes 34 can heat the edges of the film material, thereby effectively improving the stability of the saw blade during packaging. The top heating tube 33 has a power of 1000-1200W, and the side heating tubes 34 have a power of 1200-1500W. The inner wall of the heating chamber 31 is equipped with a temperature sensor, which provides real-time temperature feedback and adjusts the power of the heating tubes accordingly to control the internal temperature of the heating chamber at 150-200℃.

[0043] Working principle and usage process of this utility model: Before use, first start the servo motor 16 to drive the bidirectional lead screw 17 to rotate, so that the two sets of threaded connecting plates 22 drive the positioning structure 2 to move. By observing the corresponding position of the pointer 26 and the scale line 15, adjust the distance between the two sets of positioning rollers 25 to match the diameter of the saw blade. Then start the cylinder 13 to push the heating chamber 31 to move the heat shrink structure 3 as a whole, so that the slide seats 32 on both sides of the heating chamber 31 slide along the T-shaped slide rail 14 on the inner wall of the heating chamber 12, and adjust the height of the heat shrink structure 3 to match the thickness of the saw blade. Finally, place the saw blade with the shrink film on the conveying device 11, and the conveying device 11 will transport the saw blade to the heating chamber 31 in the heating chamber 12. During the transport process, the two sets of positioning rollers 25 will position the saw blade, and after the saw blade enters the heating chamber 12, it can move along the center position of the heating chamber 12 and the heating chamber 31. Finally, the shrink film is heated by the top heating pipe 33 and the side heating pipes 34 in the heating chamber 31, and the heat shrink packaging of the saw blade is completed.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the transmission device 11, cylinder 13, servo motor 16, top heating tube 33 and side heating tube 34 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. Furthermore, all threaded parts and movable parts in this application need to be cleaned and maintained regularly (including but not limited to dust removal, lubrication, etc.) to ensure their normal operation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
