Description

Technical Field

[0001] The invention relates to daily chemical pump assembly equipment, in particular to an assembly needle for the daily chemical pump assembly equipment. Background Art

[0002] In daily life, people can see products using daily chemical pumps everywhere, such as shampoo, shower gel, detergent, hand soap, sunscreen spray, moisturizing lotion, essence, facial cleanser, makeup remover, leather cleaner, etc. Daily chemical pumps are easy to use, hygienic, energy-saving and environmentally friendly and have been widely used in the pumping of various daily chemical products such as lotions, liquids, water, etc. Therefore, the industry has a very high demand for daily chemical pumps. The existing daily chemical pump assembly equipment can handle most of the daily chemical pumps, but the requirements for the daily chemical pump itself are relatively high. For example, the piston and the cover of the daily chemical pump need to be able to rotate so that it can rotate under the action of the pump body rubber rubbing mold.

[0003] Generally, for the convenience of use, the pump nozzle will face one side, such as left or right, and the pump nozzle will rotate as it is used. Therefore, the trademark logo or promotional logo on the bottle body rotates randomly and cannot face the customer as much as possible. In the environment of commodity homogeneity, manufacturers pay more and more attention to details and require that daily chemical pumps be installed after the bottle body with the pump nozzles facing a certain direction. On the one hand, it is conducive to the uniformity and neatness of the shelves or packaging, so that users can see it without clutter and feel comfortable. On the other hand, it can make the trademark logo or promotional logo of the lotion face the customer as much as possible during use. For daily chemical pumps that need to be equipped with specified directions, especially foam pumps, the existing daily chemical pump assembly equipment cannot meet customer needs. Manual assembly is basically adopted, which is inefficient.

[0004] In addition, the existing assembly equipment is prone to damage the pump body during the rotational assembly of the pressing head and pump body, resulting in a high rate of defective assembly of daily chemical pumps, causing property loss and customer dissatisfaction; the existing assembly production efficiency is low and the defective rate is high, which does not match the market's high demand and high quality requirements for daily chemical pumps. Summary of the invention

[0005] In order to solve the above problems, the present application provides an assembly needle for daily chemical pump assembly equipment that can assemble a variety of daily chemical pumps and greatly improve productivity and reduce defective rate. The specific implementation method is as follows:

[0006] An assembly needle for daily chemical pump assembly equipment comprises an assembly needle body, an assembly needle roller, and a reset spring, wherein the assembly needle roller is installed below the assembly needle body, and the reset spring is sleeved on the outside of the assembly needle body, and further comprises a positioning needle, a positioning spring, a positioning needle rotating shaft, and a positioning needle outer cap; a positioning groove is provided above the assembly needle body, and the positioning needle, the positioning spring, and the positioning needle rotating shaft are placed in the positioning groove, the positioning needle rotating shaft is sleeved on the upper outer side of the positioning needle, the positioning spring is sleeved on the lower outer side of the positioning needle, and the positioning needle outer cap is provided on the top of the assembly needle body, and an opening for the daily chemical pump piston to enter and exit is provided on the top of the positioning needle outer cap, and an installation groove for positioning the daily chemical pump piston is provided on the positioning needle, and the positioning needle can move up and down in the positioning groove under the action of external force.

[0007] In one or more embodiments of the present invention, a vertical slewing bearing is further included. The vertical slewing bearing is placed in the positioning groove and below the positioning spring.

[0008] In one or more embodiments of the present invention, a blocking portion is provided above the positioning pin, and the blocking portion prevents the positioning pin from moving out of the assembly pin body from the opening during movement.

[0009] In one or more embodiments of the present invention, an assembly needle guide sleeve is further included. The assembly needle guide sleeve is placed outside the assembly needle body and above the return spring. A limiting groove is provided on the assembly needle guide sleeve.

[0010] In one or more embodiments of the present invention, a sliding groove is provided on one side of the assembly needle body.

[0011] In one or more embodiments of the present invention, a protective pad is provided on the outer side of the positioning pin, and the protective pad is placed below the positioning pin rotating shaft and above the positioning spring.

[0012] In one or more embodiments of the present invention, the positioning needle shaft adopts a cylindrical roller bearing.

[0013] In one or more embodiments of the present invention, the vertical slewing bearing is a plane pressure bearing.

[0014] In one or more embodiments of the present invention, a groove is provided on the assembly needle body, and a groove hole opposite to the groove is provided on the positioning needle outer cap.

[0015] In one or more embodiments of the present invention, an exhaust channel extends from the bottom end of the positioning pin toward the mounting groove.

[0016] The beneficial implementation effect brought about by the present invention is that the pump body is positioned by the positioning pin, and the pump body rotates with the assembly star wheel. At the same time, the pump body will gradually squeeze the positioning pin downwards as the assembly pin body rises on the cam platform. The pump body rotates under the action of the pump body rubber rubbing mold, and when the slot on the pump body is aligned with the position of the pressing head, the positioning spring instantly lifts the positioning pin and the pump body, thus completing the installation of the daily chemical pump in the specified position; in addition, due to the use of the positioning pin rotating shaft and the vertical auxiliary bearing, the rotation efficiency of the pump body is improved, and at the same time, the friction of the pump body during rotation is greatly reduced, thereby improving the installation efficiency and production yield.

[0017] For daily chemical pumps that do not require a specified orientation, as long as the pump body is aligned with the pressing head, the positioning spring, the positioning needle shaft and the vertical auxiliary bearing make the installation process of the daily chemical pump faster and more accurate. After actual verification, after using the assembly needle, the scrap rate of daily chemical pumps in existing equipment is basically controlled within 0.1‰, and the assembly speed is more than 120, which is a significant improvement compared to the previous scrap rate of more than 2% and the speed of about 50-80. It has a good market promotion and application value and can meet the different needs of the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A kind of assembly needle 1 for daily chemical pump assembly equipment comprises an assembly needle body 11, an assembly needle roller 111, and a reset spring 112. The assembly needle roller 111 is installed below the assembly needle body 11, and the reset spring 112 is sleeved on the outside of the assembly needle body 11. The assembly needle roller 111 also comprises a positioning needle 12, a positioning spring 121, a positioning needle rotating shaft 122, and a positioning needle outer cap 13. A positioning groove 113 is provided above the assembly needle body 11. The positioning needle 12, the positioning spring 121, and the positioning needle rotating shaft 122 are placed in the positioning groove 113. The positioning needle rotating shaft 122 is sleeved on the upper outer side of the positioning needle 12. The positioning spring 121 is sleeved on the lower outer side of the positioning needle 12. The positioning needle outer cap 13 is covered on the top of the assembly needle body 11. The top of the positioning needle outer cap 13 is provided with an opening 131 for the daily chemical pump piston to enter and exit. The positioning needle 12 is provided with a mounting groove 123 for positioning the daily chemical pump piston. The positioning needle 12 moves up and down in the positioning groove 113 under the action of external force. It also includes a vertical rotation-assisting bearing 124, which is placed in the positioning groove 113 and below the positioning spring 121. Preferably, the positioning needle shaft 122 adopts a cylindrical roller bearing, and the vertical rotation-assisting bearing 124 adopts a plane pressure bearing. Under the action of the positioning needle shaft 122 and the vertical rotation-assisting bearing 124, the friction force of the pump body 22 during the friction rotation process is greatly reduced, which can effectively improve the assembly rate and effectively reduce the defective rate during the friction rotation process. The requirements for the daily chemical pump itself are not high, and different types of daily chemical pumps can be handled.

[0031] A blocking portion 125 is provided above the positioning needle 12, and the blocking portion 125 prevents the positioning needle 12 from moving out of the assembly needle body 11 from the opening 131 during movement. It also includes an assembly needle guide sleeve 14, which is placed outside the assembly needle body 11 and above the reset spring 112; a limiting groove 141 is provided on the assembly needle guide sleeve 14. During installation, the assembly needle guide 14 is embedded in the sleeve star wheel, and the limiting block is embedded in the limiting groove 141 to prevent the assembly needle body 11 from axial rotation, thereby ensuring that during the assembly process, the assembly needle 1 only moves up and down. In order to enable the positioning spring 121 to rebound quickly after the pump body 22 is aligned with the pressing head 21, a sliding groove 115 is provided on one side of the assembly needle body 11. When the assembly needle guide sleeve 14 is in the position of the sliding groove 115, the clamping force is weakened, and the friction force is reduced when the positioning spring 121 is reset, which is conducive to increasing the rebound speed. A protective pad 126 is provided on the outside of the positioning pin 12. The protective pad 126 is placed below the positioning pin shaft 122 and above the positioning spring 121. The protective pad 126 can effectively reduce the impact force generated by the positioning spring 121 on the positioning pin shaft 122 when resetting, thereby reducing the probability of damage to the positioning pin shaft 122.

[0032] A groove 114 is provided above the assembly needle body 11, and a groove hole 132 is provided on the positioning needle outer cap 13, which is arranged opposite to the groove 114. When the assembly needle 1 is installed, the clamping member on the device tightly assembles the positioning needle outer cap 13 and the assembly needle body 11 through the groove hole 132 and the groove 114, so that the impact force when the positioning spring 121 is reset can be prevented from separating the positioning needle outer cap 13 from the assembly needle body 11, effectively reducing unnecessary maintenance and production stoppage during the production process, and facilitating the disassembly and assembly of the assembly needle 1. As the positioning needle 12 is pressed downward, the air in the positioning groove 113 will be compressed, and an exhaust channel 127 is extended from the bottom end of the positioning needle 12 to the installation groove 123, so as to avoid overheating of the assembly needle body 11 and the parts in the positioning grooves 113 due to gas compression, resulting in damage to the parts. The exhaust channel 127 can quickly discharge the gas in the positioning groove 113, thereby reducing the large amount of heat generated by friction and increasing the service life of each component.

[0033] For a daily chemical pump 2 with a specified installation position, the commonly used structure is as follows Figure 6 As shown, a locking position 211 is provided in the pressing head 21, and a locking groove 221 is provided in the pump body 22. Only when the locking groove 221 is aligned with the locking position 211, the pressing head 21 and the pump body 22 can be tightly pressed together to complete the assembly. Figure 7 It is a flowchart of assembling a daily chemical pump 3. The assembly needle 1 is installed on the equipment. The pressing head 21 and the pump body 22 are respectively input into the assembly room along different tracks. The directions of the pressing head 21 and the pump body 22 entering the equipment room are relatively messy and have various angles. The pressing head 21 rotates under the action of the flexible pressing head rubbing mold. Due to the blocking effect of the pressing nozzle 212, the pressing head 21 cannot continue to rotate, thereby completing the positioning in a unified direction. At the same time, the piston of the pump body 22 is assembled onto the equipment needle 1. As the assembly needle 1 rises on the cam platform, the pump body 22 will gradually squeeze the positioning needle 12 downwards, and the positioning spring 121 will be squeezed accordingly. The pump body 22 will rotate under the action of the flexible pump body rubbing mold. When the slot 221 on the pump body 22 is aligned with the position 211 of the pressing head 21, the positioning spring 121 will rebound instantly to lift the positioning needle 12 and the pump body 22 due to the lack of force resistance, thus completing the installation of the daily chemical pump 2 in the specified position. The installed daily chemical pump 2 is input into the next process or the container.

[0034] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on this scheme should be regarded as within the scope of protection of this patent.
