Description

Technical Field

[0001] This utility model relates to the field of preform heating technology, specifically a bottle preform heating device. Background Technology

[0002] Blow molding of plastic bottles is a widely used plastic processing technology, mainly used to produce hollow containers (such as beverage bottles, daily chemical bottles, and medicine bottles). Its core principle is to heat the plastic raw material to form a preform (preform), then use compressed air to inflate the preform to the shape of the mold wall, and finally cool it to obtain the desired product. Before inflating the preform with compressed air, if the preform has already cooled, it needs to be heated and softened to a preset temperature by a preform heating device. Then, the heated preform is placed into the mold by hand or a robot for inflating. However, existing preform heating devices can only heat certain types of preforms. Heating different types of preforms requires changing different fixtures or increasing the number of preform heating devices, which not only reduces processing efficiency but also increases equipment investment costs. Utility Model Content

[0003] The purpose of this invention is to provide a bottle preform heating device that can heat multiple preforms simultaneously, thereby improving processing efficiency and reducing equipment investment costs, and solving the problem mentioned in the background art that existing preform heating devices cannot heat multiple types of preforms.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bottle-shaped preform heating device includes a base frame and a furnace body mounted on the base frame. The furnace body has a material inlet on its side wall. A rotating platform is rotatably mounted inside the furnace body. A plurality of circumferentially distributed clamps are evenly spaced along the top edge of the rotating platform. Each clamp is rotatably connected to the rotating platform. Each clamp includes a cylindrical part and a support flange integrally formed on the lower outer circumferential surface of the cylindrical part. A convex ring is integrally formed on the top surface of the support flange. A groove is formed between the inner circumference of the convex ring and the outer circumferential surface of the cylindrical part. A slot is provided on the top surface of the cylindrical part. A heating component is mounted on the inner wall of the furnace body.

[0006] Preferably, the heating assembly includes a heating chamber connected to the top of the furnace body and a plurality of heating tubes evenly spaced on the two side walls of the heating chamber.

[0007] Preferably, the heating chamber is a "C"-shaped tunnel structure, with both ends extending circumferentially to the material inlet, and the longitudinal section of the heating chamber is rectangular.

[0008] Preferably, the bottom wall of the heating chamber has an opening along the circumferential direction, and the top of the clamp is located at the opening.

[0009] Preferably, a first sealing groove is formed on the upper part of the inner circumferential surface of the convex ring of the clamp, and a first sealing ring is embedded in the first sealing groove; a second sealing groove is formed on the upper part of the inner circumferential surface of the slot of the clamp, and a second sealing ring is embedded in the second sealing groove.

[0010] Preferably, the bottom wall of the slot is provided with a protruding post, and a limiting groove is formed between the outer peripheral surface of the protruding post and the inner wall of the slot.

[0011] Preferably, a cooling structure is provided at the opening of the bottom wall of the heating chamber, and the cooling structure includes two cooling plates disposed opposite each other at the opening.

[0012] Preferably, both cooling plates are annular and fixed to the top surface of the rotating table, and several clamps are placed between the two cooling plates.

[0013] Preferably, each of the cooling plates has several equally spaced cooling air outlets on its side facing the fixture, and each of the cooling plates has an air inlet channel that is connected to the cooling air outlet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting a support flange, a raised ring, and a slot on the column, both the groove and the slot can be used to insert the bottle mouth without changing the clamp. This allows the clamp to heat multiple preforms at the same time, improving processing efficiency and reducing equipment investment costs.

[0016] 2. The heating chamber has a "C"-shaped tunnel structure. The "C"-shaped tunnel structure of the heating chamber helps to improve heating efficiency, reduce heat loss, and save resources. A temperature sensor is installed in the heating chamber to detect the temperature inside the heating chamber, so as to control the temperature inside the heating chamber through the heating tube to adapt to the heating of bottles of different thicknesses.

[0017] 3. During the bottle heating process, the cooling gas sprayed from the cooling outlet of the cooling plate helps to cool down the bottle mouth and the clamp, preventing the bottle mouth from softening excessively and deforming, thereby improving the bottle yield. At the same time, the first sealing ring and the second sealing ring can prevent hot air from entering the bottle mouth in the heating chamber, and also prevent the bottle mouth from softening excessively.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 A bottle-shaped preform heating device includes a base frame 1 and a furnace body 2 mounted on the base frame 1. (See also...) Figure 4 The furnace body 2 has a material inlet 21 on its side wall. The material inlet 21 is an L-shaped notch extending to the top wall of the furnace body 2 for feeding and unloading materials. A rotating platform 3 is rotatably mounted inside the furnace body 2. Several circumferentially distributed clamps 4 are evenly spaced along the top edge of the rotating platform 3 for placing bottles. All clamps 4 are rotatably connected to the rotating platform 3. (See also...) Figure 2-3 Each of the clamps 4 includes a cylindrical portion 41 and a support flange 42 integrally formed on the lower outer peripheral surface of the cylindrical portion 41. A raised ring 43 is integrally formed on the top surface of the support flange 42. A groove 44 is formed between the inner periphery of the raised ring 43 and the outer peripheral surface of the cylindrical portion for placing a bottle neck. A slot 45 is provided on the top surface of the cylindrical portion 41 for inserting a bottle neck. (See also...) Figure 1-2 as well as Figure 4The furnace body 2 has a heating component 5 installed on its inner wall to heat the bottle on the clamp 4 inside the furnace body 2 and soften it. In this embodiment, the bottom wall of the slot 45 has a protrusion 46, and a limiting groove is formed between the outer peripheral surface of the protrusion 46 and the inner wall of the slot 45. The bottle mouth is inserted into the protrusion 46, and the limiting groove limits the bottle so that the bottle can be placed stably. The top surface of the furnace body 2 has heat dissipation holes.

[0026] This utility model provides a support flange 42, a raised ring 43, and a slot 45 on the column part 41. Both the groove 44 and the slot 45 can be used to insert the bottle mouth without changing the clamp 4. This allows the clamp 4 to heat multiple bottle preforms at the same time, improving processing efficiency and reducing equipment investment costs.

[0027] Please see Figure 1 The bottle preform heating device includes a first drive mechanism 6, which comprises a base 61, a supporting main shaft 62, and a first motor 63. The base 61 is installed inside the base frame 1. The supporting main shaft 62 is rotatably mounted on the base 61 via bearings. The top end of the supporting main shaft 62 passes upward through the bottom wall of the furnace body 2 and connects to the bottom of the rotary table 3. The first motor 63 is mounted on the base 61. The output shaft of the first motor 63 is connected to a drive gear (not shown). The outer circumferential surface of the supporting main shaft 62 is provided with a driven gear (not shown) that meshes with the drive gear. When conveying bottles, the first motor 63 drives the supporting main shaft 62 to rotate via the drive gear, thereby causing the rotary table 3 at the top end of the supporting main shaft 62 to rotate, realizing the feeding of the clamp 4 in the circumferential direction.

[0028] Please see Figure 1 The bottle-shaped preform heating device includes a second drive mechanism 7. The second drive mechanism 7 includes a second motor 71 mounted on the bottom surface of the rotary table 3 and several rotating shafts 72 rotatably disposed on the rotary table 3 and distributed circumferentially. The top end of each rotating shaft 72 is connected to a corresponding clamp 4, and the bottom end of each rotating shaft 72 extends downwards to below the rotary table 3. (See also...) Figure 4 In this embodiment, the transmission method between the second motor 71 and one of the rotating shafts 72 is gear transmission, friction wheel transmission or belt pulley transmission, and the transmission method between the plurality of rotating shafts 72 is gear transmission, friction wheel transmission or belt pulley transmission. The rotation of the clamp 4 is to make the bottle heat more evenly.

[0029] Please see Figure 2 The heating assembly 5 includes a heating chamber 51 connected to the top of the furnace body 2 and several heating pipes 52 evenly spaced on both sides of the heating chamber 51. Please refer to [link to relevant documentation]. Figure 4The heating chamber 51 has a C-shaped tunnel structure, with both ends extending circumferentially to the feeding port 21. One end of the heating chamber 51 is the feeding port, and the other end is the discharging port. The longitudinal section of the heating chamber 51 is rectangular, and the bottom wall of the heating chamber 51 has an opening 511 along the circumferential direction. The top of the clamp 4 is located at the opening 511. In this embodiment, the C-shaped tunnel structure of the heating chamber 51 helps to improve heating efficiency, reduce heat loss, and achieve the purpose of saving resources. A temperature sensor is installed inside the heating chamber 51 to detect the temperature inside the heating chamber 51, so that the temperature inside the heating chamber 51 can be controlled by the heating tube 52 to adapt to the heating of bottles of different thicknesses.

[0030] Please see Figure 3 The clamp 4 has a first sealing groove on the upper part of the inner circumferential surface of the protruding ring 43, and a first sealing ring 47 is embedded in the first sealing groove; the clamp 4 has a second sealing groove on the upper part of the inner circumferential surface of the slot 45, and a second sealing ring 48 is embedded in the second sealing groove. In this embodiment, the clamp 4 is continuously heated by the heating chamber 51 during the bottle heating process, resulting in a relatively high temperature. The bottle mouth is simultaneously heated by the hot air in the heating chamber 51 and the clamp 4, which can easily cause the bottle mouth to soften excessively due to heat. Once the bottle mouth is overheated and softened, it is easily deformed by vibration or impact from other components during transportation, and it is also very easy to deform during the blowing process. Therefore, when the bottle mouth is inserted into the groove 44 or the slot 45, the first sealing ring 47 and the second sealing ring 48 can prevent the hot air in the heating chamber 51 from entering the bottle mouth, thus avoiding excessive softening of the bottle mouth.

[0031] For further details, please refer to Figure 2-3 To prevent the bottle mouth from softening, a cooling structure 8 is provided at the opening 511 on the bottom wall of the heating chamber 51. The cooling structure 8 includes two cooling plates 81 arranged opposite each other at the opening 511. Both cooling plates 81 are annular and fixed to the top surface of the rotating table 3. Several clamps 4 are placed between the two cooling plates 81. Each cooling plate 81 has several equally spaced cooling air outlets 811 on its side facing the clamps 4. Each cooling plate 81 has an air inlet channel 812 that communicates with the cooling air outlets 811. In this embodiment, the air inlet channel 812 is connected to an external air supply device to provide cooling gas. During the bottle heating process, the cooling gas sprayed from the cooling air outlets 811 of the cooling plate 81 helps to cool the bottle mouth and clamps 4, preventing the bottle mouth from softening excessively and deforming, thereby improving the bottle yield.

[0032] The working principle of this bottle preform heating device is as follows: Please refer to... Figure 1 as well as Figure 4During operation, the first motor 63 drives the support spindle 62 to rotate via the drive gear, causing the rotary table 3 at the top of the support spindle 62 to rotate as well. At the same time, the second motor 71 drives all the rotating shafts 72 and the clamps 4 on them to rotate together. The heated bottles that come out of the outlet of the heating chamber 51 are removed from the clamps 4 by manual or robotic arms, and new unheated bottles are placed on the clamps 4. The unheated bottles rotate with the rotary table 3, enter the heating chamber 51 from the inlet, and finally come out from the outlet of the heating chamber 51. This cycle is repeated to complete the heating of bottles in batches. During this process, the cooling gas sprayed from the cooling outlet 811 of the cooling plate 81 is used to cool the bottle mouth and the clamps 4 to prevent the bottle mouth from softening too much and deforming.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
