Description

Technical Field

[0001] This utility model relates to the field of plastic bucket blow molding technology, specifically a preheating device for blow molding. Background Technology

[0002] Blow molding of plastic buckets is a plastic processing method that uses gas pressure to expand a hot-melt preform to form a hollow product. Specifically, the blow molding process involves placing a heated and softened tubular plastic preform in a mold, introducing compressed air to inflate it into shape, and then cooling and demolding to obtain the finished product. This method is widely used in the production of hollow containers such as bottles, buckets, and automotive parts.

[0003] Conventional billet preheating devices require manual placement of the billet into the heating equipment, which affects the efficiency of processing operations and is time-consuming and labor-intensive, making continuous processing inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a preheating device for blow molding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a preheating device for blow molding, comprising a preheating box body and a drive assembly. A track assembly is installed inside the preheating box body. The drive assembly is mounted on the diagonal edge inside the track assembly, and a moving component is connected to the surface of the drive assembly. The drive assembly includes a fixed frame, a servo motor, a drive wheel, a transmission belt, a driven wheel, and a traction block. The servo motor is vertically mounted inside the fixed frame, and the top power output end of the servo motor is connected to the drive wheel via a coupling. The drive wheel is connected to the side surface of the drive wheel, and the driven wheel is connected to the side surface of the transmission belt closest to the vertical central axis of the track assembly. Meanwhile, a traction block is provided on the side surface of the transmission belt away from the driven wheel.

[0006] Furthermore, the track assembly includes a device frame, a precision guide rail, a stabilizing bracket, and an assembly table. The top surface of the device frame is equipped with a precision guide rail, and the side surface of the device frame closest to its vertical central axis is symmetrically and horizontally equipped with a stabilizing bracket. In addition, an assembly table is installed at each of the four diagonal points on the inner side of the device frame.

[0007] Furthermore, the stabilizing brackets are symmetrically mounted on the inner front and rear ends of the device frame, and the device frame, precision guide rail, stabilizing brackets, and assembly table are fixedly connected to each other.

[0008] Furthermore, there is one set of driving wheels and three sets of driven wheels, and the transmission belts are all meshed with the driving wheels and driven wheels.

[0009] Furthermore, the traction blocks are fixedly connected to the surface of the transmission belt and arranged in multiple sets, and the transmission belt is located on the inner side of the precision guide rail. The driving wheel and the driven wheel are each installed on the top of a set of assembly tables.

[0010] Furthermore, the moving component includes a telescopic rod, a limiting plate, a base, guide wheels, and a limiting rod. The upper and lower ends of the telescopic rod are both horizontally mounted with limiting plates, and the bottom of the limiting plate is connected to and mounted with a base. The bottom of the base is mounted with guide wheels, and two sets of limiting rods are vertically mounted on the side of the base near the transmission belt.

[0011] Furthermore, the telescopic rod is vertically installed at the four opposite corners of the two sets of limiting plates, and four sets of guide wheels are installed at the bottom of the base, with two sets of guide wheels on each side of the precision guide rail.

[0012] Furthermore, the limiting plate is made of a heat-conducting material, and the limiting rods are respectively vertically set on the left and right sides of the traction block.

[0013] This utility model provides a preheating device for blow molding blanks, which has the following beneficial effects:

[0014] 1. This utility model, by setting up a driving component, wherein two sets of limiting rods on one side of the base are respectively set on both sides of the traction block connected to the surface of the transmission belt. With this structure, the servo motor drives the drive wheel to rotate vertically, thereby driving the transmission belt connected to the side to move synchronously, thus pulling the entire moving component to move. In addition, since multiple sets of moving components are set up, the above structure allows each set of clamped blanks to enter the preheating box body one by one for preheating, thereby achieving continuous processing, ensuring the continuity and sustainability of the device operation, and thus ensuring operating efficiency.

[0015] 2. This utility model, by setting up a track assembly, wherein the entire moving assembly is clamped on the left and right sides of the precision guide rail by four sets of guide wheels at the bottom of the base. With the operation of the drive assembly, the entire moving assembly is pulled and moved horizontally along the surface of the precision guide rail. The use of the above structure can ensure the structural stability and structural support of the moving assembly as much as possible, thereby ensuring the structural stability and effectiveness of the billet conveying. In addition, since the two sets of limiting plates are connected by a telescopic rod structure, the distance between the two sets of limiting plates can be adjusted by the extensibility of the structure, thereby ensuring the clamping and fixing of the billet within a certain adjustment range, thus ensuring the structural stability of the billet during the movement. Furthermore, the limiting plates are made of thermally conductive material, which, while providing clamping and fixing, avoids affecting the preheating treatment of the billet.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

The drive assembly 3 includes a fixed frame 301, a servo motor 302, a drive wheel 303, a transmission belt 304, a driven wheel 305, and a traction block 306. The servo motor 302 is vertically mounted inside the fixed frame 301, and the drive wheel 303 is connected to the top power output end of the servo motor 302 via a coupling. The transmission belt 304 is connected to the side surface of the drive wheel 303, and the driven wheel 305 is connected to the side surface of the transmission belt 304 closest to the vertical central axis of the track assembly 2. The transmission belt 304 is further away from the driven wheel 305. One side surface of the component is provided with a traction block 306, one set of driving wheel 303 is provided, and three sets of driven wheel 305 are provided. The transmission belt 304 is meshed with the driving wheel 303 and the driven wheel 305. The traction block 306 is fixedly connected to the surface of the transmission belt 304 and arranged in multiple sets. The transmission belt 304 is located on the inner side of the precision guide rail 202. The driving wheel 303 and the driven wheel 305 are each installed on the top of a set of assembly tables 204. Two sets of limiting rods 405 on one side of the base 403 are respectively set on both sides of the traction block 306 connected to the surface of the transmission belt 304. With this structure, the servo motor 302 drives the driving wheel 303 to rotate vertically, thereby driving the transmission belt 304 connected on the side to move synchronously, thus pulling the entire moving component 4 to move.

[0022] like Figures 1 to 3As shown, the track assembly 2 includes a device frame 201, a precision guide rail 202, a stabilizing bracket 203, and an assembly table 204. The precision guide rail 202 is mounted on the top surface of the device frame 201, and the stabilizing bracket 203 is symmetrically and horizontally mounted on one side of the device frame 201 near its vertical central axis. Assembly tables 204 are mounted at the four diagonal points on the inner side of the device frame 201. The stabilizing brackets 203 are symmetrically mounted at the front and rear ends of the inner side of the device frame 201. The device frame 201, precision guide rail 202, stabilizing bracket 203, and assembly table 204 are fixedly connected to each other. The moving assembly 4 includes a telescopic rod 401, a limiting plate 402, a base 403, guide wheels 404, and a limiting rod 405. The limiting plates 402 are horizontally mounted on both the upper and lower ends of the telescopic rod 401, and the limiting plates 402 are connected to the bottom of the next lower group. A base 403 is installed, and guide wheels 404 are installed at the bottom of the base 403. Two sets of limiting rods 405 are vertically installed on the side of the base 403 near the transmission belt 304. Telescopic rods 401 are vertically installed at the four diagonal positions of the two sets of limiting plates 402. Four sets of guide wheels 404 are installed at the bottom of the base 403, and two sets of guide wheels 404 are respectively set on each side of the precision guide rail 202. The limiting plates 402 are made of heat-conducting material, and the limiting rods 405 are respectively vertically set on the left and right sides of the traction block 306. The entire moving component 4 is clamped to the left and right sides of the precision guide rail 202 by the four sets of guide wheels 404 at the bottom of the base 403. With the operation of the drive component 3, while pulling the entire moving component 4, the entire moving component 4 is also moved horizontally along the surface of the precision guide rail 202.

[0023] In summary, as Figures 1 to 3 As shown, when using this preheating device for blow molding, the blank to be processed is first placed between the two sets of limiting plates 402. At the same time, the telescopic rod 401 is used to make adaptation adjustments and ensure that the blank is clamped and fixed.

[0024] Then, the preheating box body 1 and drive assembly 3 are started. As the servo motor 302 inside the fixed frame 301 operates, the drive wheel 303 connected to it rotates and drives the transmission belt 304 meshing with the side of the drive wheel 303 to move synchronously. The driven wheel 305 installed on the top of the assembly table 204 ensures the stability of the movement of the transmission belt 304.

[0025] At this time, the entire moving assembly 4, which is connected to the traction block 306 by the limiting rod 405 on one side of the base 403, moves along the side surface of the precision guide rail 202 on the top of the device frame 201 with the assistance of the guide wheel 404. Then, the blanks held by the moving assembly 4 are fed into the interior of the preheating box body 1 one by one to achieve continuous processing.
