Description

Technical Field

[0001] This utility model relates to the field of plastic bottle filling technology, and in particular to a positioning and clamping structure for a plastic bottle sealing machine. Background Technology

[0002] A sealing machine is a mechanical device used to seal packaging containers, primarily for product preservation and preventing loss of contents. It is suitable for containers made of paper, plastic, glass, metal, and other materials, and is widely used in the food, pharmaceutical, chemical, and cosmetic industries. Its core functions include both flexible and rigid container sealing. Flexible sealing mainly uses heat-melting and adhesive technologies, such as the heat-sealing of plastic bags; rigid sealing is achieved through technologies such as screw capping, knurling, or electromagnetic induction, with typical applications including edge sealing of metal cans and tamper-evident cap forming. The equipment mainly consists of a transmission system, a heating device, and a control system. The sealing process is completed through temperature regulation and mechanical pressure. Common models include fully automatic filling and sealing machines and handheld aluminum foil sealing machines, adaptable to different container shapes and production needs.

[0003] Traditional filling and sealing machines lack a bottle clamping device, which leads to misalignment between the plastic bottle and the capping component during sealing, resulting in problems such as loose caps and leakage, affecting the product's sealing performance and shelf life. Utility Model Content

A support positioning plate is fixedly connected to the upper end of each set of support rods.

[0006] Preferably, the lifting mechanism includes: a lifting rod, which is fixedly connected to the top of the chassis, and a sleeve is fitted on the lifting rod, with rollers installed on the outer side wall of the sleeve.

[0007] The beneficial effect of adopting the above-mentioned further solution is that it can lift the plastic bottle placed on the bottle holder so that the bottle mouth of the plastic bottle is tightly sealed with the heated sealing film through the sealing head.

[0008] Preferably, the bottle holder is arc-shaped.

[0009] The beneficial effects of adopting the above-mentioned further solution are: it facilitates the arrangement of several groups of bottle holders in a circle, ensuring that each pair of bottle holders does not interfere with the others and guaranteeing the independence of the work.

[0010] Preferably, a turntable is fixedly connected to the top of the turret shaft, and a number of sealing heads are arranged around the bottom of the turntable, the number of the sealing heads corresponding to the number of the lifting mechanisms.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the lifting mechanism and the corresponding sealing head facilitate the corresponding sealing process of the plastic bottle.

[0012] Preferably, the two sets of support positioning plates are parallel to each other and located on the same horizontal plane.

[0013] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the support of the neck ring at the mouth of the plastic bottle, preventing deformation of the bottle mouth.

[0014] Preferably, an arc-shaped limiting plate is provided between the two sets of support positioning plates.

[0015] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the positioning of the bottle mouth of the plastic bottle, ensuring that the plastic bottle corresponds to the sealing head above it.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The positioning and clamping structure of the plastic bottle sealing machine of this utility model is equipped with a lifting mechanism to lift the plastic bottle placed on the bottle holder, so that the bottle mouth of the plastic bottle is tightly bonded to the heated sealing film through the sealing head. By setting two sets of symmetrical support rods and positioning plates on the bottle holder, the stiffening ring at the bottle mouth of the plastic bottle is supported, ensuring the sealing effect, preventing deformation of the bottle mouth, improving the sealing quality of plastic bottle products, reducing the defect rate, reducing raw material waste, and improving production efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figure 1-3 This utility model provides a positioning and clamping structure for a plastic bottle sealing machine: A positioning and clamping structure for a plastic bottle sealing machine includes a turret shaft 1, a base plate 2 fixedly connected to the bottom of the turret shaft 1, a number of lifting mechanisms 3 arranged around the top of the base plate 2, a bottle support 4 fixedly connected to the top of each lifting mechanism 3, two sets of support rods 5 symmetrically arranged at the top of each bottle support 4, and a support positioning plate 6 fixedly connected to the upper end of each set of support rods 5.

[0023] In this embodiment, a lifting mechanism 3 is provided to lift the plastic bottle 10 placed on the bottle holder 4, so that the bottle mouth of the plastic bottle 10 is tightly sealed with the heated sealing film through the sealing head. By providing two sets of symmetrical support rods 5 and positioning plates 6 on the bottle holder 4, the stiffening ring at the bottle mouth of the plastic bottle 10 is supported, ensuring the sealing effect, preventing deformation of the bottle mouth of the plastic bottle 10, improving the sealing quality of the plastic bottle 10 product, reducing the defect rate, reducing raw material waste, and improving production efficiency.

[0024] Furthermore, the lifting mechanism 3 includes a lifting rod 31, which is fixedly connected to the top of the chassis 2. A sleeve 32 is fitted on the lifting rod 31, and a roller 33 is installed on the outer wall of the sleeve 32.

[0025] In this embodiment, a lifting mechanism 3 is provided to lift the plastic bottle 10 placed on the bottle holder 4, so that the bottle mouth of the plastic bottle 10 is tightly sealed with the heated sealing film through the sealing head. The lifting mechanism 3 includes a top rod 31 and a sleeve 32 sleeved on the top rod 31. The sleeve 32 contains a spring. During operation, the plastic bottle 10 enters the bottle holder 4 with the external conveyor chain. The roller 33 enters the rising section of the externally fixed inclined guide rail. Under the action of mechanical force, the bottle holder 4 is pushed upward, pushing the plastic bottle 10 towards the sealing head 8. After sealing is completed, the roller 33 enters the sinking section of the external inclined guide rail, the sleeve 32 descends downward, and the plastic bottle 10 is released.

[0026] Specifically, the shape of the bottle holder 4 is arc-shaped.

[0027] In this embodiment, by providing an arc-shaped bottle holder 4, several sets of bottle holders 4 can be arranged in a circle, and the two bottle holders 4 do not interfere with each other, ensuring the independence of the work.

[0028] In addition, a turntable 7 is fixedly connected to the top of the turret shaft 1, and several sets of sealing heads 8 are arranged around the bottom of the turntable 7. The number of the several sets of sealing heads 8 corresponds to the number of the lifting mechanism 3.

[0029] In this embodiment, by providing a turntable 7, and by using a lifting mechanism 3 and a corresponding sealing head 8, it is convenient to seal the plastic bottle 10 on each lifting mechanism 3.

[0030] In addition, the two sets of support positioning plates 6 are parallel to each other and located on the same horizontal plane.

[0031] In this embodiment, two sets of support positioning plates 6 are parallel to each other and located on the same horizontal plane, which facilitates the support of the neck ring at the mouth of the plastic bottle 10 and prevents the mouth of the plastic bottle 10 from deforming.

[0032] It should be noted that an arc-shaped limiting plate 9 is provided between the two sets of support positioning plates 6.

[0033] In this embodiment, an arc-shaped limiting plate 9 is provided between the two sets of support positioning plates 6 to facilitate the limiting of the bottle mouth position of the plastic bottle 10, ensuring that the plastic bottle 10 corresponds to the sealing head 8 above.
