Description

Technical Field

[0001] This utility model relates to the field of bottle preform processing technology, and more specifically, to a heat treatment device for bottle preform processing. Background Technology

[0002] PET preforms refer to pre-made products of polyethylene terephthalate, also known as PET preforms. They are semi-finished bottles made of PET material, usually appearing as transparent or semi-transparent granules or flakes. PET preforms have a wide range of applications, including bottles for packaging beverages, cosmetics, pharmaceuticals, health products, mineral water, reagents, etc. Heat treatment equipment is required during the processing of preforms.

[0003] A search revealed a height-adjustable PET preform heat treatment device disclosed in Chinese Patent Publication No. CN 217993285 U. Although the device uses a finished product box fixing component to ensure a firm fit between the finished product box and the preform box during material receiving, allowing the preform to fall steadily into the box during unloading, the process of positioning and unpositioning the finished product box requires repeated manual pulling of the pull ring. This makes fixing and removing the finished product box from the preform box inconvenient, increases manual labor, and affects work efficiency. Therefore, this utility model designs a preform processing heat treatment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment apparatus for preform processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A preform processing heat treatment apparatus includes a base, a preform box, a pressure chamber, a finished product box, a limiting sleeve, and a slider. The preform box is mounted on the base, and the pressure chamber is mounted on the preform box. A dispensing tube assembly is mounted on the pressure chamber. A carrier is fixedly installed on the preform box near the pressure chamber, and a feeding assembly is mounted on the carrier. A photoelectric counting sensor is fixedly installed at one end of the carrier above the feeding assembly. A roller assembly is mounted at the bottom of the finished product box. L-shaped sliders are fixedly installed on both sides of the finished product box. The limiting sleeve is fixedly installed on both sides of the preform box. The L-shaped sliders and the sliders are slidably connected to the limiting sleeve. An electric push rod is fixedly installed at the upper end of the limiting sleeve. An anti-slip pad is fixedly installed on the telescopic end of the electric push rod through a positioning block. A pressure sensor is fixedly installed inside the limiting sleeve, and a spring is fixedly connected between the force-bearing end of the pressure sensor and the slider.

[0007] As a preferred embodiment of this utility model, a controller is provided on the outside of the pressure box, the output terminals of the photoelectric counting sensor and the pressure sensor are electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the input terminal of the electric push rod.

[0008] As a preferred technical solution of this utility model, the inner wall of the limiting sleeve is provided with a stop bar, which is distributed on the upper and lower sides of the inner wall of the limiting sleeve.

[0009] As a preferred embodiment of this utility model, the dispensing tube assembly includes a dispensing tube, a telescopic cylinder, and a sleeve rod. The dispensing tube is fixedly connected to the outlet end of the pressure chamber. The sleeve rod is slidably sleeved on the outside of the dispensing tube. The telescopic cylinder is fixedly installed on the pressure chamber via a side frame. A transmission ring is fixedly sleeved on the outside of the sleeve rod. The transmission ring is fixedly installed on the telescopic end of the telescopic cylinder.

[0010] As a preferred embodiment of this utility model, the bottom end of the sleeve is fixedly connected to a sealing ring outside the dispensing tube, and the sealing ring is a component made of rubber.

[0011] As a preferred embodiment of this utility model, the feeding assembly includes a rotating roller, a motor, and a feeding belt. The rotating roller is rotatably mounted on both ends of the carrier frame, the motor is fixedly mounted on the carrier frame, the drive end of the motor is fixedly connected to the end of one rotating roller, and the feeding belt is tumbled between the two rotating rollers.

[0012] As a preferred embodiment of this utility model, the roller assembly includes four movable rollers, which are respectively fixedly installed at the bottom corners of the finished product box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, by pushing the finished product box, allows the L-shaped slider to slide into the limiting sleeve. The L-shaped slider pushes the slide block, causing the spring to contract. Once the pressure sensor detects that the force has reached a preset value, the electric push rod drives the positioning block and the anti-slip pad to press against the L-shaped slider, thus fixing the finished product box on the preform box. The demolded preforms can be transported to the finished product box using a feeding belt. A photoelectric counting sensor can count the passing preforms. Once the number reaches a preset value, the electric push rod drives the positioning block and the anti-slip pad to rise and reset, allowing the finished product box to slide out along the outside of the preform box. This allows for automatic positioning and depositioning of the finished product box, making the operation convenient and simple. It makes fixing and removing the finished product box from the preform box easier, reducing manual labor and improving work efficiency. Attached Figure Description

[0029] The working principle of this utility model:

[0030] During use, the finished product box 4 is pushed, causing the L-shaped slider 402 to slide into the limiting sleeve 7. The L-shaped slider 402 pushes the slider 706 to slide, and the spring 705 contracts. When the pressure sensor 704 detects that the force has reached the preset value, the controller 8 controls the electric push rod 701 to drive the positioning block 702 and the anti-slip pad 703 to press against the L-shaped slider 402, thus fixing the finished product box 4 on the preform box 2. The motor 602 drives the rotating roller 601 to rotate, and the feeding belt 603 can transport the demolded preforms to the finished product box 4. The photoelectric counting sensor 202 can count the passing preforms. If the number reaches the preset value, the controller 8 controls the electric push rod 701 to drive the positioning block 702 and the anti-slip pad 703 to rise and reset, so that the finished product box 4 can slide out along the outside of the preform box 2. Thus, the finished product box 4 can be automatically positioned and released from positioning. The operation is convenient and simple, making it easier to fix and remove the finished product box 4 from the preform box 2.
