Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing and processing, and in particular to an adjustable spacing guide roller assembly for a strip cutting machine. Background Technology

[0002] In the production of automotive parts, materials such as automotive sealing strips and seat belts need to be cut into strips of different widths and thicknesses according to the vehicle model.

[0003] For example, utility model application CN202323589656.5 discloses an adjustable plastic film slitting machine, comprising: a base plate, with support plates fixedly connected to both the front and rear sides of the top of the base plate, a top plate welded to the top of the support plates, and two sets of strip grooves extending through the left side of the top of the top plate; a clamping mechanism, comprising two sets of clamping mechanisms respectively installed on the front and rear sides of the bottom of the top plate, for installing feeding rollers of different lengths; and an adjusting mechanism, located in the middle of the top of the top plate, for adjusting the tension of the plastic film. This utility model includes a clamping mechanism, thereby changing the distance between the mounting seats on both sides, enabling the installation of feeding rollers of different lengths. Secondly, the adjusting mechanism, through the output of a servo motor driving a drive gear to rotate, causes the sleeve and rotating frame to rotate synchronously, changing the position of the guide roller and thus adjusting the tension of the plastic film.

[0004] The aforementioned device adjusts the tension of the plastic film by rotating the rotating frame. However, in the process of cutting materials such as automotive sealing strips and seat belts, the existing device may experience wear on the rotating frame after long-term operation. Wear on the rotating frame can easily lead to uneven force on one side, causing material displacement and resulting in substandard cut strip dimensions.

[0005] Therefore, this application proposes an adjustable spacing guide roller assembly for a strip cutting machine. Utility Model Content

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-pitch guide roller assembly for a strip cutting machine includes: a strip cutting machine frame assembly, which includes a frame body placed on the ground and a cutting blade component installed in the cavity of the frame body for strip cutting; a guide roller assembly, which is disposed in the cavity of the frame body and located in front of the cutting blade component; the guide roller assembly includes a guide roller body, a mounting plate, a fixing plate, and a rotating shaft; rectangular grooves are formed on both inner walls of the frame body; there are two sets of mounting plates and fixing plates, each set located in a corresponding rectangular groove; and multiple sets of first gears are fixedly passed through the rotating shaft; a transmission assembly is disposed on one outer wall of the frame body for adjusting the horizontal position of the guide roller body; the transmission assembly includes a rectangular mounting plate, a second rack, and a lead screw; a lifting block is fixedly installed on one side of the second rack, and the lifting block is driven by the lead screw.

[0008] According to the adjustable spacing guide roller group for the slicing machine, a feeding roller is also provided in the cavity of the frame body. The feeding roller is closer to the front end of the frame body than the guide roller body, and the vertical height of the feeding roller is lower than that of the guide roller body.

[0009] According to the adjustable spacing guide roller group for the strip cutting machine, the guide roller body is movably installed between two sets of mounting plates via bearings. The two sets of fixing plates are fixedly installed on the side of the two sets of mounting plates that are far apart from each other. Guide rods are fixedly installed on both sides of the two sets of fixing plates. Guide holes are opened on the inner wall of both sides of the rectangular groove at the positions of the corresponding guide rods, and the guide rods are movably engaged in the corresponding guide holes.

[0010] According to the adjustable spacing guide roller group for the strip cutting machine, the rotating shaft is located below the guide roller body, and the bottom ends of the two sets of fixed plates are fixedly connected with a first rack, which is movably meshed with the corresponding first gear.

[0011] According to the adjustable spacing guide roller group for the strip cutting machine, the rectangular assembly plate is fixedly installed on one side of the outer wall of the frame body, and a fixed pile is fixedly installed on one side of the rectangular assembly plate. One end of the rotating shaft is movably installed in the rectangular groove, and the other end of the rotating shaft movably passes through another set of rectangular grooves and is movably installed on the fixed pile through a bearing.

[0012] According to the adjustable spacing guide roller group for the strip cutting machine, the rotating shaft is fixedly connected to the frame body with a second gear, the second gear is movably meshed with the second rack, a lifting groove is opened on one side of the rectangular assembly plate, the second rack is movably engaged in the lifting groove, and a lifting block on one side of the second rack is movably engaged in the lifting groove.

The lead screw is movably installed in the lifting groove. A handwheel is movably installed at the top of the rectangular assembly plate. The shaft of the handwheel movably passes through the lifting groove and is fixedly connected to one end of the lead screw. A dust cover is movably engaged with the rectangular assembly plate.

[0014] This invention provides an adjustable spacing guide roller assembly for a strip cutting machine. It has the following advantages: (1) This application sets a rotating handwheel to drive the lead screw to rotate. The lead screw drives the second rack through the lifting block, and the second gear and the rotating shaft rotate in conjunction.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-5 As shown, this utility model is an adjustable spacing guide roller assembly for a strip cutting machine, including a strip cutting machine frame assembly. The strip cutting machine frame assembly includes a frame body 101 placed on the ground and a cutting blade component 102 installed in the cavity of the frame body 101 for cutting strips. The frame body 101 serves as the main support frame, and the cutting blade component 102 completes the cutting of materials. A feeding roller 103 is also provided in the cavity of the frame body 101. The feeding roller 103 is set as a front feeding roller 103. The feeding roller 103 is closer to the front end of the frame body 101 than the guide roller body 201. The vertical height of the feeding roller 103 is lower than that of the guide roller body 201. The height difference between the feeding roller 103 and the guide roller body 201 forms a natural tension zone, which avoids material slippage or wrinkling and helps to improve the flatness of the cut.

[0020] like Figure 3-4As shown, the guide roller assembly is disposed within the cavity of the frame body 101 and is located in front of the cutting blade component 102. The guide roller assembly includes a guide roller body 201, a mounting plate 203, a fixing plate 204, and a rotating shaft 206. Rectangular grooves 202 are formed on both inner walls of the frame body 101. The mounting plate 203 and fixing plate 204 are in two sets, each set located within a corresponding rectangular groove 202. The guide roller body 201 is movably mounted between the two sets of mounting plates 203 via bearings, enabling rotational guidance. Guide rods 205 are fixedly mounted on both sides of the two sets of fixing plates 204. Guide holes are formed on the inner walls of both sides of the rectangular grooves 202 at the positions corresponding to the guide rods 205, allowing the guide rods 205 to movably engage with the corresponding guide rods 205. Inside the guide hole, the fixed plate 204 slides in cooperation with the guide hole of the rectangular groove 202 through the guide rod 205. The two sets of fixed plates 204 are fixedly installed on the side of the two sets of mounting plates 203 that are far apart from each other. The rotating shaft 206 is located below the guide roller body 201. The rotating shaft 206 is fixedly connected to multiple sets of first gears 207. The bottom ends of the two sets of fixed plates 204 are fixedly connected to the first racks 208. The first racks 208 are movably meshed with the corresponding first gears 207. The rotation of the rotating shaft 206 causes the multiple sets of first gears 207 to rotate synchronously. The rotation of the first gears 207 causes the first racks 208 to drive the fixed plate 204, the guide rod 205 and the guide roller body 201 to move horizontally synchronously. The linkage between the first gears 207 and the first racks 208 realizes synchronous adjustment on both sides, avoiding material displacement caused by uneven force on one side.

[0021] like Figure 5As shown, the transmission assembly 301 is mounted on one outer wall of the frame body 101 and is used to adjust the horizontal position of the guide roller body 201. The transmission assembly 301 includes a rectangular mounting plate 302, a second rack 305, and a lead screw 306. A lifting block is fixedly installed on one side of the second rack 305, and the lifting block is in transmission cooperation with the lead screw 306. The second rack 305 is threadedly connected to the lead screw 306 through the lifting block. The rotation of the lead screw 306 causes the lifting block and the second rack 305 to move up and down synchronously. The rectangular mounting plate 302 is fixedly mounted on the frame body. On one side of the outer wall of the body 101, a fixed post 303 is fixedly installed on one side of the rectangular assembly plate 302. One end of the rotating shaft 206 is movably installed in the rectangular groove 202, and the other end of the rotating shaft 206 movably passes through another set of rectangular grooves 202 and is movably installed on the fixed post 303 through a bearing. A second gear 209 is fixedly inserted through the rotating shaft 206 outside the frame body 101. The second gear 209 is movably meshed with the second rack 305, so that the second rack 305 rises and falls, driving the second gear 209 and the rotating shaft 206 to rotate synchronously. A lifting groove 304 is provided on one side. A second rack 305 is movably engaged in the lifting groove 304. A lifting block on one side of the second rack 305 is movably engaged in the lifting groove 304. The lifting block moves within the lifting groove 304. A lead screw 306 is threadedly connected to the lifting block and is movably installed in the lifting groove 304. A handwheel 307 is movably installed on the top of the rectangular assembly plate 302. The shaft of the handwheel 307 movably passes through the lifting groove 304 and is fixedly connected to one end of the lead screw 306. The operator rotates the handwheel 307 to drive the lead screw 306 to rotate. When the lead screw 306 rotates, the lifting block and the second rack 305 move up and down synchronously. The movement of the second rack 305 drives the second gear 209 and the rotating shaft 206 to rotate synchronously. In turn, the rotation of the first gear 207 causes the first rack 208 to drive the fixed plate 204, the guide rod 205 and the guide roller body 201 to move horizontally synchronously, thus completing the horizontal adjustment of the position of the guide roller body 201. The rectangular assembly plate 302 is movably engaged with the dust cover 308, which can prevent dust and accidental contact, protect the structure of the device and extend its service life.

[0022] The implementation principle of this utility model of an adjustable spacing guide roller group for a strip cutting machine is as follows: First, the stepped height difference design between the feeding roller 103 and the guide roller body 201 creates a natural tension zone during the material conveying process, effectively preventing material slippage or wrinkling and ensuring the flatness of the material before cutting. The feeding roller 103 is lower than the guide roller body 201, using gravity to enhance the material tension effect.

[0023] Secondly, rotating the handwheel 307 drives the lead screw 306, which in turn drives the second rack 305 to rise and fall. Through the meshing transmission between the second gear 209 and the rotating shaft 206, the first gear 207 rotates synchronously, driving the first rack 208 to move the guide roller body 201 horizontally. The fixed plate 204 slides with the guide hole of the rectangular groove 202 through the guide rod 205 to ensure the stability of movement.

[0024] Finally, a dust cover 308 is snapped onto one side of the rectangular assembly plate 302, which can prevent dust and accidental contact, protect the device structure, and extend its service life.

[0025] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
