Description

Technical Field

[0001] The utility model relates to the field of zippers, in particular to a zipper color adjusting device. Background Art

[0002] Zippers are connectors that connect or separate items by means of continuously arranged chain teeth. They are now widely used in clothing, bags, tents, etc. Zippers can be divided into nylon zippers, resin zippers, and metal zippers according to the materials. Resin zipper teeth are produced by dyeing polyester plastic rice and injection molding through an injection molding machine. Before injection molding, the plastic rice and masterbatch need to be mixed evenly in a mixer to avoid color differences in the produced zippers, and then the mixed materials are fed into the feed port of the injection molding machine. Since the feed port of the existing vertical injection molding machine commonly used for injection molding zippers is usually set at a higher position, the mixed material needs to be transferred to the injection molding machine and then lifted to the high feed port by manual or lifting devices before feeding. Therefore, after the mixing is completed, two steps of transferring and lifting the materials are required, which makes the feeding step more troublesome. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] See also Figure 1-Figure 6 The present embodiment is a zipper color adjusting device, comprising a feeding mechanism 1, a lifting device 2 and a stirring mechanism 3. The lifting device 2 is provided with a feed port 21 and a discharge port 22. The feed port 21 is located at the lower part of the lifting device 2. The feeding mechanism 1 is provided with multiple feed ports 21 of the lifting device 2 and are all located at the feed ports 21 of the lifting device 2. The feeding mechanism 1 feeds quantitatively into the lifting device 2. The discharge port 22 is located at the upper part of the lifting device 2. The stirring mechanism 3 is arranged in the lifting device 2, and the stirring mechanism 3 moves and rotates up and down through the lifting device 2.

[0024] When the utility model is used, a plurality of feeding mechanisms 1 are used to quantitatively feed materials such as plastic rice and masterbatch into the feed port 21, and the materials enter the stirring mechanism 3 located at the feed port 21. After a quantitative amount of materials are fed into the stirring mechanism 3, the stirring mechanism 3 moves upward under the action of the lifting device 2 and the stirring mechanism itself rotates, so that the materials in the stirring mechanism 3 can be turned over to achieve uniform stirring. When the stirring mechanism 3 moves to the discharge port 22, the materials in the stirring mechanism 3 are output through the discharge port 22. The position of the discharge port 22 can correspond to the feed port 21 of the injection molding machine, so that the materials can enter the injection molding machine. Therefore, the utility model can simultaneously realize the two steps of stirring and lifting the materials, simplifying the feeding steps of the injection molding machine and improving the feeding efficiency.

[0025] See also Figure 1 The lifting device 2 includes a shell 23, a driving wheel 24, and a driven wheel 25. The driving wheel 24 and the driven wheel 25 are rotatably arranged at the upper and lower parts of the shell 23 respectively. The driving wheel 24 is driven to rotate by a first motor 26 arranged on one side of the shell 23. The front and rear sides of the driving wheel 24 and the driven wheel 25 are both sleeved with synchronous belts 27, and the stirring mechanism 3 is arranged on the synchronous belt 27.

[0026] The first motor 26 drives the driving wheel 24 to rotate, driving the synchronous belt 27 to rotate, thereby driving the stirring mechanism 3 to circulate between the feed port 21 and the discharge port 22. The stirring mechanism 3 continuously stirs the material and feeds it into the injection molding machine. The lifting device 2 has the advantages of simple structure and easy installation and maintenance.

[0027] In this embodiment, the first motor 26 is a stepper motor, so that the stirring mechanism 3 can stop when it moves to the position of the feed port 21, and cooperate with the feeding mechanism 1 to input materials into the stirring mechanism 3.

[0028] See also Figure 1 , Figure 2 The stirring mechanism 3 includes a plurality of rollers 31 arranged at equal intervals on the synchronous belt 27. The front and rear ends of the rollers 31 are respectively fixed on the two synchronous belts 27 through brackets 32. The rollers 31 are connected to the brackets 32 in a damping rotation manner. The housing 23 and the rollers 31 are respectively provided with mutually meshing racks 33 and gears 34.

[0029] The first motor 26 drives the synchronous belt 27 to rotate so that the multiple rollers 31 on the synchronous belt 27 can receive the material at the feed port 21 in turn. When the roller 31 moves upward, the meshing transmission action of the rack 33 and the gear 34 drives the roller 31 to rotate to achieve stirring of the material. Finally, the roller 31 moves to the discharge port 22 to output the material. Therefore, the utility model can achieve continuous stirring and output of the material by arranging multiple rollers 31 on the synchronous belt 27, thereby improving the efficiency of outputting the mixed material of the utility model.

[0030] See also Figure 1 , Figure 2 The feed port 21 and the discharge port 22 are respectively arranged on the left and right sides of the shell 23. A support seat 28 is arranged in the shell 23. The left and right sides of the support seat 28 are located between the two synchronous belts 27. A plurality of racks 33 are arranged and are alternately arranged on the inner wall of the shell 23 and the left and right sides of the support seat 28. When the roller 31 moves upward, a single rack 33 engages with the gear 34 to drive the roller 31 to rotate half a circle.

[0031] The rack 33 provided on the shell 23 and the support seat 28 is alternately meshed with the gear 34 on the drum 31 for transmission, so that while the drum 31 moves upward under the action of the synchronous belt 27, the drum 31 rotates half a circle alternately clockwise and counterclockwise under the action of the gear 34 and the rack 33, thereby improving the stirring effect on the material and thus improving the uniformity of the material after mixing.

[0032] See also Figure 2 , Figure 3 , Figure 6 The drum 31 is in the shape of a hollow cylinder with an opening on the side. An arc-shaped baffle 35 is fitted on the outer side of the drum 31. The bottom of the baffle 35 is fixed to the bracket 32 ​​by bypassing the gear 34 through a U-shaped connecting piece 37. When the opening 36 of the drum 31 rotates and moves downward, the baffle 35 fits and covers the opening 36 of the drum 31.

[0033] First, the drum 31 is located on the left side of the housing 23. When the opening 36 of the drum 31 is facing upward, the baffle 35 does not cover the opening 36 (such as Figure 2 As shown in the figure, the material can enter the drum 31 through the feed opening 21; when the drum 31 rotates so that its opening 36 gradually moves downward, the baffle 35 covers the opening 36 to prevent the material from falling out of the opening 36 (as shown in the figure). Figure 2When the roller 31 passes through the top rack 33, the opening 36 of the roller 31 faces upward, the baffle 35 does not cover the opening 36, and the roller 31 moves around the driving wheel 24 under the action of the synchronous belt 27 and moves to the right side of the housing 23. Since the roller 31 and the bracket 32 ​​are connected in a damped rotational connection, the roller 31 does not rotate at this time, so when the roller 31 moves to the right side of the housing 23, the opening 36 of the roller 31 faces downward, so that the material in the roller 31 can be poured out and output through the discharge port 22 (as shown in FIG. Figure 6 When the roller 31 moves around the driven wheel 25 and moves to the left side of the housing 23 under the action of the synchronous belt 27, the opening 36 of the roller 31 continues to receive the material upward, so that the roller 31 can work continuously and the automation degree of the utility model is improved.

[0034] See also Figure 2 A first guide plate 4 is provided at the bottom of the feed port 21. The left end of the first guide plate 4 is hinged to the shell 23 and is limited by the shell 23 so that the right end of the first guide plate 4 tilts downward.

[0035] When the roller 31 moves to the feed port 21, the right end of the first guide plate 4 extends into the opening 36 of the roller 31. After the material enters the feed port 21, it is input into the roller 31 through the first guide plate 4. After the input is completed, the roller 31 moves upward under the action of the synchronous belt 27, and the first guide plate 4 is lifted up by the roller 31 and rotates upward until the roller 31 is separated from the first guide plate 4. The first guide plate 4 rotates downward under the action of its own gravity and maintains the right end in a slanted downward state under the limiting action of the upper limit block of the shell 23, which is used to guide the material to the next roller 31. The first guide plate 4 is used to ensure that the material put into the feeding mechanism 1 each time can enter the roller 31, thereby reducing the risk of material spilling and accumulating at the bottom of the shell 23 to hinder the operation of the utility model.

[0036] See also Figure 4 , Figure 5 The feeding mechanism 1 is arranged in multiple pieces in a front-to-back arrangement, the feeding end 11 of the feeding mechanism 1 is funnel-shaped, the discharging end 12 of the feeding mechanism 1 is located above the feeding port 21, and a feeding screw 13 is arranged in the feeding mechanism 1, and the feeding screw 13 is driven to rotate by a second motor 14 on one side of the feeding mechanism 1.

[0037] The feeding end 11 of the feeding mechanism 1 is funnel-shaped, which can facilitate manual feeding or docking with the feeding mechanism 1 of the material.

[0038] In this embodiment, the second motor 14 adopts a servo motor, which can control the rotation angle more accurately, so that the amount of material fed into the feed port 21 each time is controlled by controlling the rotation angle of the feeding screw 13 through the second motor 14, thereby reducing the difference in the amount of material fed each time, thereby ensuring that the proportion of different materials fed into the drum 31 each time is basically the same, thereby reducing the color difference of the zipper after injection molding.

[0039] See also Figure 6 A second guide plate 5 is provided on the shell 23, and the left end of the second guide plate 5 is rotatably connected to the front and rear inner walls of the shell 23 and is limited by the shell 23. The second guide plate 5 is driven to maintain an oblique lower right state by a torsion spring 51 provided between the second guide plate 5 and the shell 23. The second guide plate 5 is provided at the upper left oblique position of the discharge port 22.

[0040] When the roller 31 moves to the discharge port 22, the opening 36 of the roller 31 faces downward, the material in the roller 31 is poured out, and the material falls on the inclined second guide plate 5 and slides down, and the material falls into the discharge port 22 in a parabolic trajectory, and then the roller 31 moves downward under the action of the synchronous belt 27 and presses against the second guide plate 5, and the second guide plate 5 rotates until the roller 31 is separated from the second guide plate 5. The second guide plate 5 rotates upward under the action of the torsion spring 51 and maintains the right end in a downward slanted state under the limiting action of the upper limit block of the shell 23, which is used for guiding the next roller 31 to reduce the situation where the material cannot fall into the discharge port 22 when it is poured out.

[0041] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
