Description

Technical Field

[0001] The utility model relates to the technical field of chain guiding, and more specifically, the utility model relates to an arbitrarily bendable chain guiding jig. Background Art

[0002] Extruded, pressed, and injected products are produced by a production device that pulls straight electronic components or other structural components together with solid glue from the die opening of the extrusion, pressing, and injection device to integrally extrude, press, and inject regular and irregular strip-shaped appearance products.

[0003] Since it cannot be confirmed whether the electronic components or other structural components are straight, bent, or deformed before entering the extrusion, pressing, and injection device, it is impossible to ensure that the cross-section of the extruded, pressed, and injected products is within the dimensional tolerance range. Therefore, it is necessary to use a positioning groove to limit the chain.

[0004] However, in actual use, due to the structure of the positioning groove with an open upper end, and when the chain is viewed laterally inside the positioning groove, when the chain speed is too fast, the chain will be detached from the inside of the positioning groove, thus affecting the transmission of the chain. Summary of the Utility Model

[0005] The arbitrarily bendable chain guiding jig provided by the utility model aims to solve the following problem: the existing positioning groove has an open upper end structure, and when the chain is viewed laterally inside the positioning groove, when the chain speed is too fast, the chain will be detached from the inside of the positioning groove, thus affecting the transmission of the chain.

[0006] To achieve the above object, the utility model provides the following technical solution: an arbitrarily bendable chain guiding jig, including a bakelite positioning groove and a chain body. The bakelite positioning groove is used to carry the chain body. The bakelite positioning groove has an open upper end structure, and multiple one-way limiting members are arranged outside the bakelite positioning groove. The one-way limiting member includes a first limiting frame, the first limiting frame is connected to the bakelite positioning groove, symmetric positioning pulleys are arranged inside the first limiting frame, the positioning pulleys are located inside the bakelite positioning groove, the gap between the two positioning pulleys is smaller than the width of the chain body inside the bakelite positioning groove, and the positions of the multiple one-way limiting members on the bakelite positioning groove are different, so as to limit both sides of different positions of the chain body, and prevent the chain body from detaching from the bakelite positioning groove.

[0007] In a preferred embodiment, a two-way limiting member is arranged at the input end of the chain body of the bakelite positioning groove. The two-way limiting member includes a second limiting frame, the second limiting frame is installed at the input end of the chain body on the bakelite positioning groove, two groups of transverse pulleys are symmetrically arranged inside the second limiting frame, the gap between the two groups of transverse pulleys is parallel to the bakelite positioning groove, and the two-way limiting member is used for positioning the chain body up and down and left and right, so as to straighten and limit the transmission of the chain body.

[0008] In a preferred embodiment, the bottoms of the two positioning pulleys are in contact with the surface of the chain body, and the height inside the bakelite positioning groove is limited by the positioning pulleys, thereby limiting the position of the chain body.

[0009] In a preferred embodiment, grooves are symmetrically formed on one side of the second limiting frame away from the bakelite positioning groove, and longitudinal pulleys are provided inside the two grooves.

[0010] In a preferred embodiment, the chain body is located at the gap between the two sets of transverse pulleys.

[0011] In a preferred embodiment, the first limiting frame and the second limiting frame are both structures with open upper ends.

[0012] The beneficial effects of the utility model are:

[0013] 1.

DETAILED DESCRIPTION

[0020] The present application will be further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Referring to the attached Figures 1 to 4 specification, a chain guiding jig that can be bent arbitrarily includes a bakelite positioning groove 1 and a chain body 2. The bakelite positioning groove 1 is used to carry the chain body 2. The bakelite positioning groove 1 has an open upper end structure, and a plurality of one-way limiting members 3 are provided outside the bakelite positioning groove 1; the one-way limiting member 3 includes a first limiting frame 31, the first limiting frame 31 is connected to the bakelite positioning groove 1, and positioning pulleys 32 are symmetrically arranged inside the first limiting frame 31. The positioning pulleys 32 are located inside the bakelite positioning groove 1, and the gap between the two positioning pulleys 32 is smaller than the width of the chain body 2 inside the bakelite positioning groove 1. The positions of the plurality of one-way limiting members 3 on the bakelite positioning groove 1 are different, so as to limit both sides of different positions of the chain body 2, and prevent the chain body 2 from detaching from the bakelite positioning groove 1.

[0022] It should be noted that the number of the one-way limiting members 3 is set to three, and it can also be set to more than three. The number of the one-way limiting members 3 is changed according to the length of the bakelite positioning groove 1. By installing the one-way limiting members 3 at different positions on the bakelite positioning groove 1, different positions of the chain body 2 are restricted, and the phenomenon that the chain body 2 bulges and detaches during the transmission inside the bakelite positioning groove 1 is prevented.

[0023] Furthermore, a two-way limiting member 4 is provided at the input end of the chain body 2 of the bakelite positioning groove 1. The two-way limiting member 4 includes a second limiting frame 41. The second limiting frame 41 is installed at the input end of the chain body 2 on the bakelite positioning groove 1. Two groups of transverse pulleys 42 are symmetrically arranged inside the second limiting frame 41. The gap between the two groups of transverse pulleys 42 is parallel to the bakelite positioning groove 1. The two-way limiting member 4 is used to position the chain body 2 vertically and horizontally, so as to straighten and limit the transmission of the chain body 2.

[0024] It should be noted that the two-way limiting member 4 is installed at one end of the bakelite positioning groove 1 where the chain body 2 enters. Since the chain body 2 can be bent arbitrarily, when the chain body 2 enters the inside of the bakelite positioning groove 1 through the two-way limiting member 4, the tail end of the chain body 2 will swing automatically under the action of tension. The two-way limiting member 4 plays a role in limiting the tail end of the chain body 2, and avoids the chain body 2 getting stuck at the entrance end of the bakelite positioning groove 1.

[0025] Furthermore, the bottoms of the two positioning pulleys 32 are in contact with the surface of the chain body 2, and the height inside the bakelite positioning groove 1 is restricted by the positioning pulleys 32, so as to limit the chain body 2.

[0026] It should be noted that since the positioning pulley 32 is located above the bakelite positioning groove 1 and the internal dimensions of the first limiting frame 31 match the external dimensions of the bakelite positioning groove 1, the positioning pulley 32 is in contact with the surface of the chain body 2 inside the bakelite positioning groove 1, realizing the height limitation inside the bakelite positioning groove 1 and enabling the chain body 2 to move parallelly inside the bakelite positioning groove 1;

[0027] When the chain body 2 moves, it contacts the positioning pulley 32, driving the positioning pulley 32 to move inside the first limiting frame 31, which can not only reduce the friction generated on the chain body 2, but also achieve the effect of positioning transmission.

[0028] Furthermore, referring to the attached drawings of the specification Figure 2 and Figure 3 , symmetric grooves are provided on one side of the second limiting frame 41 away from the bakelite positioning groove 1, and longitudinal pulleys 43 are provided inside both grooves.

[0029] Furthermore, the chain body 2 is located at the gap between the two groups of transverse pulleys 42.

[0030] Furthermore, both the first limiting frame 31 and the second limiting frame 41 have a structure with an open upper end.

[0031] It should be noted that through the transverse pulleys 42 and longitudinal pulleys 43 provided on the inner and outer sides of the second limiting frame 41, the limiting transmission of two surfaces is realized. And since the chain body 2 is located at the gap between the two longitudinal pulleys 43, the longitudinal pulleys 43 are in contact with the upper and lower surfaces of the chain body 2, which can not only limit the upper and lower surfaces of the chain body 2, but also reduce the friction between the chain body 2 and the transverse pulleys 42;

[0032] When the chain body 2 moves inside the bakelite positioning groove 1, the tail end of the chain body 2 exposed outside the bakelite positioning groove 1 will swing as the chain body 2 moves rapidly. When the chain body 2 swings, it contacts the longitudinal pulley 43, causing the longitudinal pulley 43 to rotate on the second limiting frame 41, realizing the limitation of the edge of the second limiting frame 41 and reducing the phenomenon of jamming between the chain body 2 and the second limiting frame 41, thereby achieving the effect of straightening and transmitting the chain body 2.

[0033] Working principle: First, place the chain body 2 inside the second limiting frame 41, insert both sides of the chain body 2 into the gap between the two transverse pulleys 42, pass the chain body 2 out from the bottom of the positioning pulley 32, and transmit the chain body 2 through the traction force of the production equipment.

[0034] Then, according to the length of the bakelite positioning groove 1, the position of the first limit frame 31 on the bakelite positioning groove 1 is adjusted so that multiple first limit frames 31 are evenly installed on the bakelite positioning groove 1, which can limit different positions of the chain body 2 and avoid the chain body 2 getting stuck on the bakelite positioning groove 1.

[0035] By means of the positioning pulley 32 in cooperation with the transverse pulley 42 and the longitudinal pulley 43, the chain body 2 is limited in multiple directions, so that the chain body 2 can move parallelly inside the bakelite positioning groove 1. This not only corrects the chain body 2 and changes the bent chain body 2 into a straight shape, but also prevents the chain body 2 from detaching from the bakelite positioning groove 1, thereby improving the transmission efficiency of the chain body 2.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
