Technical field

The utility model relates to embroidery machines.

Background technique

Colour changing guide rail currently on the market is as shown in Figure 1, using common rail, including what is connect with head shell 1 It guide 11 and is connect with needle bar frame and can be along the sliding block 12 of 11 linear slide of guide, when there are many needle number, in order to guarantee The shift motion of guide rail, guide 11 are made long, influence the installation of auxiliary device at left and right sides of head, while also will limit embroidery Flower machine minimal head away from.

Utility model content

Technical problem to be solved in the utility model is just to provide a kind of colour changing guide rail, can avoid the too long limitation of length and embroiders Flower machine minimal head away from.

Solve above-mentioned technical problem, the utility model adopts the following technical solution: a kind of colour changing guide rail, including with head shell The guide and connect with needle bar frame and can include to sliding block along the sliding block of guide linear slide, the guide that body connects The row for playing the main rolling element of a row of support and guiding role and being arranged in the either above or below of the main rolling element of this row is auxiliary Rolling element is helped, the auxiliary rolling element assists main rolling element to play support and guiding role to sliding block.

Preferably, the main rolling element is equipped with guide channel along excircle, and the sliding block is equipped with the guiding cooperated with guide channel Item.

Preferably, the diameter of the main rolling element is greater than the diameter of auxiliary rolling element.

Preferably, the quantity of the main rolling element is greater than the quantity of auxiliary rolling element.

Preferably, the center of the auxiliary rolling element and the center of main rolling element are staggered in sliding block glide direction.

Preferably, a row assists rolling element in the both ends concentrated setting of guide.

Preferably, a row assists rolling element quantity to be four and be respectively arranged two at the both ends of guide.

Preferably, the main rolling element and auxiliary rolling element are all made of bearing.

Preferably, the rear end face of the auxiliary rolling element is rearwardly offset from main rolling element rear end face.

The utility model additionally provides a kind of embroidery machine, is equipped with above-mentioned colour changing guide rail.

The utility model assists rolling element cooperation to play support and guiding role to sliding block using the main rolling element of a row and a row, It replaces original common rail, has the following beneficial effects:

Firstly, the cooperation of original sliding block and common rail needs longer length of fit, in order to guarantee that needle bar frame laterally moves Dynamic maximum distance, it is necessary to assure common rail has enough length, and technical solutions of the utility model, sliding block and rolling element Cooperation, relative to common rail, then can shorten length of fit, same to meet cooperation and require, it can thus be avoided too long Track stretches out head shell two sides.

Secondly, original common rail is damaged, then whole secondary guide rail is needed to change, technical solutions of the utility model only need The rolling element for replacing damage, substantially reduces maintenance time, reduces maintenance cost.

Specific embodiment

It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Be to the description only actually of at least one exemplary embodiment below it is illustrative, never as to this is practical Novel and its application or any restrictions used.Based on the embodiments of the present invention, those of ordinary skill in the art are not having Every other embodiment obtained under the premise of creative work is made, is fallen within the protection scope of the utility model.

Embodiment one, a kind of shown referring to figs. 2 and 3, colour changing guide rail, including the guide 11 being connect with head shell 1 And it is connect with needle bar frame and can include that support is risen to sliding block 12 along the sliding block 12 of 11 linear slide of guide, the guide 11 With the main rolling element 111 of a row of guiding role, the either above or below of the main rolling element 111 of a row is equipped with a row and assists main rolling Kinetoplast 111 plays the auxiliary rolling element 112 of support and guiding role to sliding block 12.

In the present embodiment, a row preferably being equipped in the lower section of the main rolling element 111 of this row and assisting rolling element 112, this is Since needle bar frame dead weight is larger, by being disposed over for the main rolling element 111 of this row, for carry needle bar frame and Sliding block.

With reference to shown in Fig. 3 and Fig. 4, sliding block 12 is equipped with sliding slot 121, and the main rolling element 111 is equipped with guide channel along excircle, The sliding block 12 is equipped with the director strip 122 cooperated with guide channel, and sliding block and guide is avoided to be detached from.

Further, the diameter of the main rolling element 111 is greater than the diameter of auxiliary rolling element 112.The main rolling element 111 Quantity be greater than auxiliary rolling element 112 quantity.Since auxiliary rolling element 112 is that the main rolling element 111 of auxiliary plays branch to sliding block 12 Support and guiding role, therefore diameter and quantity may be less than main rolling element 111, advantageously reduce cost.Similarly, in order into one Step reduces cost, rolling element 112 can be assisted in the both ends concentrated setting of guide one row, while meeting needle bar frame When moving laterally to maximum distance, sliding block 12 and main rolling element 111 and auxiliary rolling element 112 still meet cooperation and require.In this reality It applies in example, a row assists 112 quantity of rolling element to be four and be respectively arranged two at the both ends of guide, due to reducing The quantity of rolling element 112 is assisted, therefore significantly reduces cost.

Refering to what is shown in Fig. 2, the center of the auxiliary rolling element 112 and the center of main rolling element 111 are in sliding block glide direction On be staggered.Refering to what is shown in Fig. 4, the rear end face of the auxiliary rolling element 112 is rearwardly offset from main 111 rear end face of rolling element.In this way, main The cooperation of rolling element 111 and auxiliary rolling element 112 is more stable to the support of sliding block 12 and guiding.

The present embodiment is preferred, and the main rolling element 111 and auxiliary rolling element 112 are all made of bearing.Bearing is relative to general Logical rolling element, frictional force is small, wears small, operation smoothness.

Embodiment two, a kind of embroidery machine are equipped with above-mentioned colour changing guide rail, and when colour changing, needle bar frame is with respect to head shell 1 Transverse shifting, sliding block 12 and main rolling element 111 and the auxiliary cooperation of rolling element 112 on needle bar frame.

In addition to above preferred embodiment, for the utility model there are also other embodiments, those skilled in the art can root It is made various changes and modifications according to the utility model, without departing from the spirit of the utility model, should belong to the utility model Range defined in claims.
