Description

Technical Field

[0001] This utility model relates to blow molding machines, and more particularly, to a heating device for a blow molding machine. Background Technology

[0002] Currently, Chinese Patent CN202357442U discloses a heating device for a plastic blow molding machine, including a support frame and a plurality of support rods arranged parallel to each other from top to bottom on the support frame, each support rod being perpendicular to the support frame. The plurality of support rods includes a plurality of first lamp support rods and at least two adjacent second lamp support rods. Each first lamp support rod has a lamp clamp at its head, and a heating lamp is inserted into each lamp clamp. A first locking frame is installed between the heads of two adjacent second lamp support rods. This locking frame has a vertical side and a plurality of horizontal sides spaced apart on the vertical side, and each horizontal side is a locking hook. However, in the above heating device, the first lamp support rods are fixed to the support frame by bolts. Therefore, when it is necessary to change the horizontal position of the heating lamps, the bolts on the support frame must be loosened one by one before the first lamp support rods can be moved horizontally one by one, resulting in a long adjustment time. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a heating device for a blow molding machine, which has the advantage of requiring less time for adjustment.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a heating device for a blow molding machine, including a heating base and a support frame disposed on the side of the heating base, the support frame including an upper connecting plate fixedly installed on the upper part of the heating base, a lower connecting plate fixedly installed on the lower part of the heating base, and a support rod fixedly installed between the upper connecting plate and the lower connecting plate;

[0005] The support rod is provided with a plurality of lamp clamping mechanisms along the axial direction. Each lamp clamping mechanism includes a fixed seat fixedly installed on the support rod, an adjusting support rod slidably installed in the fixed seat in the horizontal direction, a chuck fixedly installed at the end of the adjusting support rod, and a limiting bolt threadedly connected to the side of the fixed seat. The threaded section of the limiting bolt abuts against the adjusting support rod.

[0006] It also includes an opening and closing control mechanism, which includes a servo motor fixedly mounted on the upper connecting plate, a drive gear fixedly mounted on the output end of the servo motor, a driven gear fixedly mounted on the head of each of the limit bolts, and a transmission rack slidably disposed on the side of the fixed seat. The transmission rack meshes with the drive gear and all the driven gears.

[0007] With the above technical solution, when the horizontal position of the heating lamp needs to be adjusted, the servo motor drives the drive gear to rotate counterclockwise. The drive gear drives the transmission rack to move downwards vertically. The transmission rack, through the driven gear, drives the corresponding limit bolt to rotate counterclockwise, causing the threaded section of the limit bolt to separate from the corresponding adjusting rod. The operator can then control the adjusting rod to move horizontally to change the horizontal distance between the heating lamp and the preform. When the heating lamp is moved to the appropriate position, the servo motor drives the drive gear to rotate clockwise. The drive gear drives the transmission rack to move upwards vertically. The transmission rack, through the driven gear, drives the corresponding limit bolt to rotate clockwise, causing the threaded section of the limit bolt to abut against the corresponding adjusting rod.

[0008] The opening and closing control mechanism can tighten or loosen multiple limit bolts at once, which reduces the time required for lamp adjustment and makes the adjustment of the heating device more convenient.

[0009] Preferably, a T-shaped guide block is fixedly installed on the side of the fixed base, a guide base is fixedly installed on the side of the transmission rack, a T-shaped guide groove is opened on the side of the guide base, and the T-shaped guide block is slidably disposed in the T-shaped guide groove.

[0010] Through the above technical solution, the T-shaped guide block and the T-shaped guide groove can not only guide the sliding of the transmission rack, making it less likely for the transmission rack to deviate during the sliding process, but also limit the transmission rack, making it less likely for the transmission rack to detach from the heating device.

[0011] Preferably, a limit stop is provided on the upper side of the guide base, and the limit stop is used to abut against the upper end of the lower connecting plate during the downward movement of the transmission rack.

[0012] Through the above technical solution, the limiting block can abut against the upper end of the lower connecting plate during the downward movement of the transmission rack, thereby limiting the transmission rack and making it difficult for the transmission rack to slide down and detach from the heating device.

[0013] Preferably, a buffer spring is fixedly installed at the lower end of the limiting block, and the central axis of the buffer spring is parallel to the central axis of the support rod.

[0014] With the above technical solution, if the transmission rack accidentally slips off during installation, the buffer spring can cushion the fall of the transmission rack after contacting the lower connecting plate, making the limit block and the transmission rack less prone to deformation or even damage.

[0015] Preferably, a buffer rubber plate is fixedly installed at the lower end of the buffer spring, and the buffer rubber plate is parallel to the lower connecting plate.

[0016] With the above technical solution, the buffer rubber plate is parallel to the lower connecting plate. In this way, when the transmission rack slides down, the buffer rubber plate contacts the lower connecting plate first, so that the buffer spring is less likely to tilt when it contracts and deforms.

[0017] Preferably, a guide post is fixedly installed at the upper end of the buffer rubber plate, and a guide hole is provided through the limiting block from top to bottom, with the guide post slidably disposed in the guide hole.

[0018] Through the above technical solution, the guide post and the guide hole cooperate with each other to play a limiting and guiding role in the extension and retraction of the buffer spring, so that the buffer spring is not easy to become skewed during the extension and retraction process.

[0019] Preferably, the side of the adjusting support rod is provided with an abutting plane, and the threaded section of the limiting bolt abuts against the abutting plane.

[0020] The above technical solution, through the cooperation of the abutment plane and the limiting bolt, can restrict the circumferential rotation of the adjusting rod. Furthermore, adding the abutment plane increases the contact area between the adjusting rod and the limiting bolt, improving the stability of the connection.

[0021] Preferably, the fixing seat is sleeved on the outside of the support rod, and a positioning bolt is threadedly connected to the side of the fixing seat, with the threaded section of the positioning bolt abutting against the support rod.

[0022] With the above technical solution, the fixing base is detachably connected to the support rod by positioning bolts, so the operator can change the vertical spacing of the heating lamp tubes as needed, thereby further improving the applicability of the heating device.
