[0002] In order to bidirectionally stretch-blow-form a preform, an injection-molded product made of PET, into a bottle, the preform must be heated to a temperature at which it can be stretched and deformed. As a method for heating the preform, an infrared lamp (near-infrared heater) that generates near-infrared rays is generally used as a heat source, and a plurality of such near-infrared heaters are arranged in parallel and parallel to the axial direction of the preform being conveyed, and the output of each near-infrared heater is adjusted to heat the preform so that its temperature distribution along the axial direction reaches the desired temperature distribution.

[0003] During the production process, multiple infrared radiation heaters are required to adjust their shapes according to the shapes of the products to achieve the purpose of uniformly controlling the temperature of the bottle body. However, the existing temperature units are controlled by independent screws, and the screws need to be unscrewed one by one for adjustment, which is more troublesome. In addition, the adjusted temperature units cannot be self-locking and are prone to position displacement due to collision, and are not very applicable.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a temperature unit shape adjustment structure for a bottle production line is proposed. Utility Model Content

[0005] The utility model aims to provide a temperature unit shape adjustment structure for a bottle production line to solve the problems raised in the above background technology.

[0007] Furthermore, a plurality of adjustment holes are provided in the middle of the ear plate, and the adjustment holes correspond to the positions and the number of the self-locking components, and the adjustment holes are provided at equal intervals along the extension direction of the ear plate.

[0008] Furthermore, a lock buckle protrudes from the side of the opening of the adjustment hole, and the lock buckle is snap-fitted with a lock groove at one end of the rotating pin.

[0009] Furthermore, a gear rod is slidably arranged inside the adjustment hole, and adjacent tooth-shaped gaps of the gear rod are engaged with a clamping block at the other end of the rotating pin.

[0010] Furthermore, a push-pull rod is fixed to the opposite surface of the rear end of the gear rod, and a bracket is fixed to the opposite surface of the front end of the gear rod, and an infrared radiation heater is arranged inside the bracket.

[0011] Furthermore, cranks are rotatably arranged at the upper and lower ends of the ear plate, and pressure rods are connected to the ends of the cranks.

[0012] Furthermore, the bottom of the pressure rod is fixed to a crank at one end, and the top of the pressure rod protrudes from the crank at the other end to form a handle.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use and the position of a certain temperature unit needs to be adjusted independently, the user presses the rotating pin with the fingertips to rotate it in the corresponding bearing seat on the outer side of the ear plate, and engages the locking groove opened at the rear end of the rotating pin with the locking buckle on the side of the adjustment hole. At this time, the card block at the front end of the rotating pin is disengaged from the engagement with the outer tooth shape of the corresponding gear rod, so that the user can adjust the position of the infrared radiation heater by pushing and pulling the rod, and then unlocks the rotating pin.

[0020] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] like Figures 1 to 3 As shown, a shape adjustment structure of a temperature unit of a bottle production line includes a back plate 1 and a self-locking component 13. A reflective plate 2 is fixed by screws on the front of the back plate 1, and ear plates 3 are fixed integrally on both sides of the back plate 1. Several self-locking components 13 are fixed on the outer side of the ear plate 3. The self-locking component 13 includes a bearing seat 1301, a rotating pin 1302, a clamping block 1303, a locking groove 1304 and a spring 1305. A rotating pin 1302 is rotated inside the bearing seat 1301, and a clamping block 1303 is fixed at one end of the rotating pin 1302. A locking groove 1304 is provided at the other end of the rotating pin 1302, and the middle part of the rotating pin 1302 is elastically connected to the ear plate 3 through a spring 1305. When adjusting the position of a certain temperature unit, the user presses the rotating pin 1302 with the fingertips to make it rotate in the corresponding bearing seat 1301 on the outer side of the ear plate 3, and the locking groove 1304 opened at the rear end thereof is engaged with the locking buckle 5 on the side of the adjustment hole 4. At this time, the block 1303 at the front end of the rotating pin 1302 is disengaged from the engagement with the outer tooth shape of the corresponding gear rod 6, so that the user can adjust the position of the infrared radiation heater 9 through the push-pull rod 7. After that, the rotating pin 1302 is unlocked, and the block 1303 is engaged with the outer tooth shape of the gear rod 6 again under the action of the reset force of the spring 1305, so as to realize the self-locking after the position of the temperature unit is adjusted, and prevent the temperature unit from being displaced under the impact of external force.

[0022] like Figures 1 to 3As shown, several adjustment holes 4 are opened in the middle of the ear plate 3, and the adjustment holes 4 correspond to the positions and numbers of the self-locking components 13, and the adjustment holes 4 are opened at equal intervals along the extension direction of the ear plate 3, and a lock buckle 5 is protruded from the side of the opening of the adjustment hole 4, and the lock buckle 5 is snap-fitted with the lock groove 1304 at one end of the rotating pin 1302, a gear rod 6 is slid inside the adjustment hole 4, and the adjacent tooth gaps of the gear rod 6 are snap-fitted with the block 1303 at the other end of the rotating pin 1302, a push-pull rod 7 is fixed to the opposite surface of the rear end of the gear rod 6, and a bracket 8 is fixed to the opposite surface of the front end of the gear rod 6, and an infrared radiation heating is arranged inside the bracket 8. Device 9, cranks 10 are rotatable at the upper and lower ends of the ear plate 3, and a pressure rod 11 is connected to the end of the crank 10, the bottom of the pressure rod 11 is fixed to the crank 10 at one end, and the top of the pressure rod 11 protrudes from the crank 10 at the other end to form a handle 12. When it is necessary to adjust the positions of several temperature units in batches, the user controls the crank 10 at the end of the ear plate 3 to rotate through the handle 12, so that the pressure rod 11 and the rear ends of several rotating pins 1302 are synchronously contacted and pressed, and multiple self-locking components 13 can be realized. Synchronous self-locking, which is convenient for users to adjust the positions of the infrared radiation heaters 9 in batches through the push-pull rod 7, is more convenient to use.
