Description

Technical Field

[0001] The present invention relates to the technical field of food and medicine packaging machinery, and in particular to a spray bottle pump head tightening device, a tightening method and a spray bottle filling machine. Background Art

[0002] Currently, the filling and sealing of spray products on the market generally utilizes intermittent rotary filling and sealing equipment with a rotary pump head. This system rotates the bottle to a certain station, stops, completes the corresponding process, and then rotates to the next station to complete the next process. This cycle tightens the pump head, making continuous production impossible. Furthermore, due to the specific characteristics of the pump packaging material, the equipment's stable production capacity is generally less than 100 pieces per minute, making it unable to meet the requirements of high-demand products. Furthermore, for products with long straws, the straws are prone to bending and deformation, making it difficult to accurately insert the straw into the bottle, reducing the product qualification rate. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a spray bottle pump head tightening device which has a simple and reliable structure and is conducive to improving production efficiency and product qualification rate.

[0004] The invention further provides a method for tightening a pump head of a spray bottle.

[0005] The present invention further provides a spray bottle filling machine comprising the spray bottle pump head tightening device.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A spray bottle pump head tightening device comprises a rotating seat, a bottle body clamping assembly and a pump head tightening assembly; a pump head inlet dial wheel, a bottle inlet dial wheel and a bottle outlet and waste rejection dial wheel are provided on the side of the rotating seat; the bottle body clamping assembly is provided with multiple and arranged circumferentially on the lower part of the rotating seat; the pump head tightening assembly is provided with multiple and arranged circumferentially on the upper part of the rotating seat; a guide assembly for guiding the tube is provided between the bottle body clamping assembly and the pump head tightening assembly.

[0012] A method for tightening a spray bottle pump head comprises the following steps:

[0013] S1. Pump head feeding: The rotating seat drives the bottle clamping assembly, pump head tightening assembly and guide assembly to rotate continuously. When the pump head tightening assembly rotates to dock with the pump head inlet dial, it grabs the pump head on the pump head inlet dial, and the guide assembly clamps the upper end of the straw. Then, the pump head tightening assembly drives the pump head and straw to rise. The straw is straightened by the guide assembly during the rising process.

[0014] S2, bottle feeding: when the bottle clamping assembly rotates to dock with the bottle feeding wheel, it clamps the bottle conveyed by the bottle feeding wheel;

[0015] S3. Tighten the pump head: The pump head tightening assembly drives the pump head and the straw down. When the straw is inserted into the bottle, the guide assembly releases the straw, and the pump head tightening assembly tightens the pump head onto the bottle. Then, the pump head tightening assembly separates from the pump head.

[0016] S4. Bottle discharging: When the bottle clamping assembly rotates to dock with the bottle discharging and rejecting dial wheel, the bottle is released and the bottle discharging and rejecting dial wheel discharges the bottle.

[0017] A spray bottle filling machine comprises a bottle unscrambling device and a filling device located downstream of the bottle unscrambling device. The above-mentioned spray bottle pump head tightening device is provided downstream of the filling device.

[0018] As a further improvement of the above technical solution: a buffer track is provided between the bottle unscrambling device and the filling device.

[0019] As a further improvement of the above technical solution: the filling device is a tracking filling device.

[0020] As a further improvement of the above technical solution: two groups of pump head sorting components are provided on the side of the pump head inlet dial wheel, and the single-row output track of each group of pump head sorting components is connected to the pump head inlet dial wheel through a pump head delivery dial wheel.

[0021] Compared with the prior art, the advantages of the present invention are: the spray bottle pump head tightening device disclosed in the present invention arranges the pump head inlet dial wheel, bottle inlet dial wheel and bottle outlet rejection dial wheel on the side of the rotating seat, and multiple groups of pump head tightening components and bottle body clamping components are provided on the rotating seat.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] Figures 1 to 4 An embodiment of the spray bottle pump head tightening device of the present invention is shown. The spray bottle pump head tightening device of this embodiment includes a rotating base 1, a bottle body clamping assembly 51 and a pump head tightening assembly 52. The side of the rotating base 1 is provided with a pump head inlet dial wheel 2, a bottle inlet dial wheel 3 and a bottle outlet and waste rejection dial wheel 4 (in this embodiment, the rotating base 1 rotates clockwise, and accordingly, the pump head inlet dial wheel 2, the bottle inlet dial wheel 3 and the bottle outlet and waste rejection dial wheel 4 are also arranged in the clockwise direction). The bottle body clamping assembly 51 is provided with multiple and is arranged circumferentially at the lower part of the rotating base 1. The pump head tightening assembly 52 is provided with multiple and is arranged circumferentially at the upper part of the rotating base 1. A guide assembly 53 for guiding the tube is provided between the bottle body clamping assembly 51 and the pump head tightening assembly 52.

[0034] The spray bottle pump head tightening device arranges the pump head inlet dial wheel 2, the bottle inlet dial wheel 3 and the bottle outlet and waste rejection dial wheel 4 on the side of the rotating base 1, and multiple groups of pump head tightening components 52 and bottle body clamping components 51 are provided on the rotating base 1. The pump head tightening component 52 and the bottle body clamping component 51 are driven by the rotating base 1 to rotate continuously, so that the pump head can be tightened continuously, which is beneficial to improving the production efficiency of the equipment compared with intermittent equipment; a guide component 53 is provided between the pump head tightening component 52 and the bottle body clamping component 51, and when the straw 93 is lifted, the guide component 53 straightens the straw 93, and can provide a guiding effect for the straw 93 when the straw 93 is lowered and inserted into the bottle body 91, which is beneficial to increasing the accuracy of the straw 93 being inserted into the bottle body 91, thereby improving the qualified rate of the product.

[0035] Furthermore, in this embodiment, the guide assembly 53 includes a pair of clamping rods 531 and a clamping drive 532 for driving the pair of clamping rods 531 to open and close. The inner sides of the clamping rods 531 are provided with arcuate guide grooves 533 (i.e., the arcuate guide groove 533 is located between the pair of clamping rods 531). When the pump head tightening assembly 52 grabs the pump head 92 and lifts it upward, the pair of clamping rods 531 form guide holes through the arcuate guide grooves 533 and clamp the straw 93, effectively straightening the straw 93. When the straw 93 is lowered and inserted into the bottle body 91, the arcuate guide grooves 533 provide guidance for the straw 93, ensuring accurate insertion of the straw 93 into the bottle body 91. This results in a simple and reasonable structure.

[0036] In a preferred embodiment, the clamping drive member 532 is a driving cylinder, which drives the ends of the pair of clamping rods 531 with arcuate guide grooves 533 to move toward or away from each other. Of course, in other embodiments, other driving methods can also be used to drive the pair of clamping rods 531 to open and close, which will not be repeated here.

[0037] Furthermore, in this embodiment, a pump head sorting assembly 6 is provided on the side of the pump head inlet dial 2, and the scattered pump heads 92 can be sorted into rows by the pump head sorting assembly 6, and then the pump heads 92 can be separated into independent individuals by the pump head inlet dial 2, so as to facilitate the grabbing of the pump head tightening assembly 52.

[0038] Furthermore, in this embodiment, the pump head arrangement assembly 6 includes a buffer hopper 61, a pump head arrangement hopper 62, and a single-row output track 63. The buffer hopper 61, the pump head arrangement hopper 62, the single-row output track 63, and the pump head inlet dial wheel 2 are sequentially connected. The buffer hopper 61 is used to buffer a sufficient amount of pump heads 92 to reduce the number of loading times. The pump heads 92 in the buffer hopper 61 fall into the pump head arrangement hopper 62, which arranges the scattered and disordered pump heads 92 into rows and outputs them through the single-row output track 63. The pump head inlet dial wheel 2 separates the pump heads 92 into individual units, making them easier to grasp by the pump head tightening assembly 52. The structure is simple and reliable, which is conducive to improving the production efficiency of the equipment.

[0039] Example 2

[0040] Figure 5 An embodiment of the method for tightening the pump head of a spray bottle of the present invention is shown. The method for tightening the pump head of a spray bottle of this embodiment includes the following steps:

[0041] S1, pump head 92 feed: see Figure 5 a to Figure 5As shown in b, the rotating seat 1 drives the bottle clamping assembly 51, the pump head tightening assembly 52 and the guide assembly 53 to rotate continuously. When the pump head tightening assembly 52 rotates to dock with the pump head inlet dial 2, the pump head 92 on the pump head inlet dial 2 is grabbed, and the guide assembly 53 clamps the upper end of the straw 93 (specifically, the arc-shaped guide groove 533 holds the straw 93). Then, the pump head tightening assembly 52 drives the pump head 92 and the straw 93 to rise. During the rising process, the straw 93 is straightened by the guide assembly 53;

[0042] S2, bottle 91 feeding: see Figure 5 b. When the bottle clamping assembly 51 (not shown) rotates to dock with the bottle feed dial wheel 3, it clamps the bottle 91 delivered by the bottle feed dial wheel 3 so that the pump head tightening assembly 52 can tighten the pump head 92 onto the bottle 91;

[0043] S3, tighten the pump head 92: see Figure 5 c Figure 5 d. The pump head tightening assembly 52 drives the pump head 92 and the straw 93 downward. After the straw 93 is inserted into the bottle 91, the guide assembly 53 releases the straw 93, and the pump head tightening assembly 52 tightens the pump head 92 onto the bottle 91. Then, the pump head tightening assembly 52 rises and separates from the pump head 92.

[0044] S4, bottle out: see Figure 5 d. When the bottle clamping assembly 51 rotates to dock with the bottle ejection and rejection wheel 4, the bottle 91 is released, the bottle ejection and rejection wheel 4 outputs the bottle 91, and then the bottle clamping assembly 51, the pump head tightening assembly 52 and the guide assembly 53 return to the original position. Figure 5 The state shown in a is repeated.

[0045] The spray pump head tightening method realizes the continuous production of pump head tightening, thereby improving production efficiency and product qualification rate.

[0046] Example 3

[0047] Figure 6 An embodiment of the spray bottle filling machine of the present invention is shown. This embodiment includes a bottle unscrambling device 7 and a filling device 10 located downstream of the unscrambling device 7. The aforementioned spray bottle pump head tightening device is located downstream of the filling device 10. Bottles 91 are arranged into a row by the bottle unscrambling device 7 and then transported to the filling device 10 via a bottle conveyor mesh belt, a bottle conveyor wheel, etc. The filling device 10 then fills the bottles 91. The filled bottles 91 are then transferred to the bottle feed wheel 3 of the spray bottle pump head tightening device by the bottle conveyor wheel, a bottle conveyor auger, etc., completing the tightening process of the pump head 92 and achieving continuous filling and sealing.

[0048] The spray bottle filling machine comprises the above-mentioned spray bottle pump head tightening device, and thus also has the above-mentioned advantages.

[0049] Furthermore, in this embodiment, a buffer track 20 is provided between the bottle unscrambling device 7 and the filling device 10. The buffer track 20 can buffer the bottles 91 before filling, while reducing the risk of bottles falling due to impact between the bottles 91.

[0050] As a preferred embodiment, the filling device 10 is a tracking filling device. The use of a tracking filling device is beneficial to improving filling efficiency and ensuring the accuracy of filling volume.

[0051] Furthermore, in this embodiment, two sets of the aforementioned pump head arrangement assemblies 6 are provided on the side of the pump head inlet dial 2. The single-row output track 63 of each set of pump head arrangement assemblies 6 is docked with the pump head inlet dial 2 via a pump head delivery dial 64. The two sets of pump head arrangement assemblies 6 respectively arrange the pump heads 92 into rows and deliver them to the pump head delivery dial 64. The pump head inlet dial 2 integrates the two pump head delivery dials 64, effectively solving the problem of low production capacity in the pump head 92 arrangement process and ensuring consistent production rhythm at each station of the entire machine.

[0052] As a preferred embodiment, the bottle-discharging and waste-rejecting dial wheel 4 is connected to a bottle-discharging mesh belt 8 , and unqualified products are rejected by the bottle-discharging and waste-rejecting dial wheel 4 , and qualified products are output through the bottle-discharging mesh belt 8 .
