Description

Technical Field

[0001] This utility model belongs to the technical field of emulsion filling equipment, specifically relating to a quick change-of-size structure and system for standard parts. Background Technology

[0002] To accommodate filling operations on containers of different sizes, filling machines need to replace corresponding parts; these parts are called standard parts. Standard parts can be a single part or a combination of multiple parts. The process of changing standard parts of different sizes according to different products is called changeover.

[0003] Existing emulsion filling machines typically use fasteners such as bolts and nuts to secure standard parts to the frame. Therefore, changing the type of part requires the use of tools for disassembly and assembly, which can easily lead to operational errors and results in low operational efficiency. Utility Model Content

[0004] To address the shortcomings of the prior art, the purpose of this utility model is to provide a quick changeover structure and system for standard parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0025] <Example>

[0026] refer to Figure 1 and Figure 5In this embodiment, the quick changeover system 10 is used to quickly replace and place the standard parts 30 mounted on the frame 20 of the emulsion filling machine. In this embodiment, the standard part 30 is used as a filling mechanism as an example. The quick changeover system 10 includes a quick changeover structure 11 and a changeover and placement cart 12.

[0027] refer to Figures 1 to 4 The quick-change structure 11 for standard parts includes a lower base 111, an upper base 112, and two locking handle parts 113.

[0028] refer to Figures 1 to 3 The lower base 111 is fixedly mounted on the frame 20 for mounting the upper base 112 and the specification part 30. Its upper surface is provided with two long strip-shaped lock lug receiving grooves 111a arranged symmetrically in its length direction.

[0029] The outer side of the lower base 111 is also provided with two positioning holes 111b that are respectively connected to the two lock lug receiving grooves 111a.

[0030] refer to Figures 1 to 3 The upper base 112 is fixedly installed at the bottom of the specification part 30, and its lower surface can fit against the lower surface of the lower base 111. It is provided with two lock ears 112a that are symmetrically arranged and correspond to the two lock ear receiving grooves 111a.

[0031] The outer side of the upper base 112 is also provided with two symmetrically arranged hanging ears 112b.

[0032] In this embodiment, the upper surface of the lower base 111 is provided with two symmetrically arranged positioning pins 111c, and the lower surface of the upper base 112 is provided with two limiting holes (not shown in the figure) that match the two positioning pins 111c.

[0033] refer to Figures 1 to 4 Two locking handles 113 correspond to two positioning holes 111b respectively. Each locking handle 113 includes a locking shaft 113a, a handle 113b, and a connecting rod 113c that connects the handle 113b to one end of the locking shaft 113a.

[0034] The other end of the locking shaft 113a has a positioning shaft section 113d and a first eccentric shaft section 113e. The first eccentric shaft section 113e is eccentrically located at the end of the positioning shaft section 113d away from the handle 113b, and its diameter is smaller than the diameter of the positioning shaft section 113d.

[0035] In this embodiment, a second eccentric shaft segment 113f is also provided at the other end of the positioning shaft segment 113d near the handle 113b. This second eccentric shaft segment 113f is eccentrically positioned relative to the positioning shaft segment 113a, and its diameter is larger than that of the positioning shaft segment 113a. The eccentric direction of the second eccentric shaft segment 113f relative to the positioning shaft segment 113d is opposite to the eccentric direction of the first eccentric shaft segment 113e relative to the positioning shaft segment 113d. Correspondingly, the positioning hole 111b is a first-order hole, with its larger diameter section located on the outer side and matching the second eccentric shaft segment 113f, and its smaller diameter section located on the inner side and matching the positioning shaft segment 113d.

[0036] refer to Figure 1 and Figure 5 The replacement placement vehicle 12 includes a movable base 121, a lifting mechanism 122, and a lifting platform 123.

[0037] The movable base 121 is used to mount the lifting mechanism 122 and the lifting platform 123, and has four casters 121a at the bottom.

[0038] The lifting mechanism 122 is mounted on the movable base 121 and is existing technology, such as using a cylinder structure, which will not be described in detail here.

[0039] The lifting platform 123 is mounted on the lifting mechanism 122 and can move up or down under the drive of the lifting mechanism 122. The front end of the lifting platform 123 is provided with two support hooks 123a that match the two lugs 112b on the upper base 112 respectively, and the rear end is provided with a hand handle 123b.

[0040] refer to Figure 1 and Figure 5 In this embodiment, the working process of the quick changeover system 10 for standard parts is as follows:

[0041] Step S1: Disconnect the pipes and other connections between the specification part 20 and other components, move the handle 113b to loosen the locking shaft 113a from locking the lock lug 112a, and remove the locking handle part 113.

[0042] Step S2: Push the transfer cart 12 forward so that the two support hooks 12a are directly below the two hanging ears 112b; the lifting mechanism 122 drives the lifting platform 123 to rise, thereby causing the two support hooks 12a to rise and insert into the two hanging ears 112b respectively (e.g., Figure 5 (as shown), and then rise to the preset height.

[0043] Step S3: Push the changeover placement cart 12 backward, thereby moving the specification parts 30 on it off the frame 20, and placing the specification parts 30 on the changeover placement cart 12 (e.g., Figure 6(As shown), for future use. At this time, the height of the lifting platform 123 can be adjusted according to actual needs.

[0044] Step S4, push the replacement placement cart 12 (e.g., containing the new specification part 30) to the side. Figure 6 (As shown) Move forward to the position of the lower base 111, and adjust the height of the lifting platform 123 and its upper specification parts 30 to be higher than the height of the lower base 111 by means of the lifting mechanism 122.

[0045] Step S5, continue to push the replacement placement cart 12 forward until the two locking lugs 112a of the upper base 112 of the new specification part 30 are exactly above the two locking lug receiving slots 111a of the lower base 111.

[0046] In step S6, the lifting mechanism 122 drives the lifting platform 123 to descend, which in turn drives the upper base 112 to descend, so that the two locking lugs 112a are inserted into the two locking lug receiving slots 111a; at this time, the two positioning pins 111c on the lower base 111 are also inserted into the two limiting holes on the upper base 112.

[0047] In step S7, the lifting mechanism 122 continues to operate, driving the lifting platform 123 to continue to descend, thereby causing the two supporting hooks 123a to disengage from the two hanging ears 112b on the upper base 112.

[0048] Step S8: Move the replacement placement cart 12 to the preset position; then, insert the locking shafts 113a of the two locking handles 113 into the corresponding positioning holes 111b, and rotate the handles 113b to lock the upper base 112 and the lower base 111. This completes one replacement of a standard part.

[0049] Functions and effects of the embodiments

[0050] According to the quick change-up structure and system for standard parts involved in this embodiment, because it has a lower base, an upper base, and a locking handle, the locking handle has a locking shaft and a handle connected to one end of the locking shaft. The other end of the locking shaft has a positioning shaft section and a first eccentric shaft section eccentrically disposed at the end of the positioning shaft section away from the handle. The diameter of the first eccentric shaft section is smaller than the diameter of the positioning shaft section. The lower surface of the upper base has two symmetrically arranged locking ears that match the first eccentric shaft section. The upper surface of the lower base has two locking ear receiving grooves that correspond to the two locking ears respectively. The outer side of the lower base has two positioning holes that communicate with the two locking ear receiving grooves respectively and match the positioning shaft section. Therefore, this embodiment utilizes the cooperation relationship between the first eccentric shaft section of the locking shaft and the locking ears of the upper base. Only by turning the locking handle can the standard parts be quickly locked onto the frame or quickly separated, thereby achieving the purpose of quick change-up of standard parts. Moreover, there is no need to use fasteners such as bolts and nuts, which reduces the risk of operational errors, makes operation convenient, and greatly improves the change-up efficiency of standard parts.

[0051] In addition, because the positioning shaft section is provided with a second eccentric shaft section that is eccentrically set to the other end of the positioning shaft section, the diameter of the second eccentric shaft section is larger than the diameter of the positioning shaft section, and the positioning hole is a first-order hole with a large diameter section that matches the second eccentric shaft section and a small diameter section that matches the positioning shaft section, the locking effect of the locking handle is greatly improved.

[0052] In addition, because the upper surface of the lower base is provided with two symmetrically arranged positioning pins, and the lower surface of the upper base is provided with two limiting holes that match the two positioning pins respectively, the stability and reliability of locking the upper and lower bases together are further improved.

[0053] In addition, because the outer side of the upper base has two symmetrically arranged hanging ears, the changeover placement cart has two support hooks that match the two hanging ears respectively, which can easily and quickly remove the standard parts from the frame and place them on the changeover placement cart, eliminating the need to find another place to place the standard parts, and also facilitating the next installation of the standard parts.

[0054] In addition, the rear end of the lifting platform is equipped with a hand lever, which makes it easy to hold and operate the transfer and placement vehicle.

[0055] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
