Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding machines, in particular to a parison head flow regulating valve. Background Art
[0002] In the prior art, since the screw and the adjusting rod are separate and closely connected, the current method for adjusting the flow rate of the glue outlet nozzle of the machine head is: when the amount of glue is reduced, the screw is rotated, and the screw pushes the adjusting rod to extend the adjusting rod into the glue outlet nozzle. When the amount of glue is increased, the adjusting rod is returned to the glue outlet nozzle position by the pressure of the glue, so that the glue nozzle can pass more glue. Since the internal pressure of the machine head is unstable, when the amount of glue needs to be reduced, the adjusting rod needs to be pushed back by the pressure of the flowing glue, resulting in the inability to accurately control the amount of glue, and it is difficult to ensure accuracy and stability. Utility Model Content
[0003] In order to effectively solve the problems in the above-mentioned background technology, the utility model proposes a parison head flow regulating valve.
[0004] The specific technical solutions are as follows:
[0005] A parison head flow regulating valve comprises an adjusting rod and a screw rod, wherein the adjusting rod and the screw rod are detachably connected together, and the adjusting rod is inserted from the side of a glue outlet nozzle to adjust the flow of the glue outlet nozzle.
[0006] Preferably, the valve body is provided with a stepped hole, the threaded sleeve is embedded in one end of the stepped hole, one end of the threaded sleeve is threaded, and the other end is provided with a guide groove, and the right end of the adjusting rod is slidably matched with the guide groove.
[0007] Preferably, the right end portion of the adjusting rod is provided with a T-shaped slot, one end of the screw rod is connected to the T-shaped slot, and the rod body of the screw rod is threadedly connected to the threaded sleeve.
[0008] Preferably, the right end portion of the adjusting rod is square.
[0009] Compared with the prior art, the beneficial effects of the utility model are: the screw and the adjusting rod are redesigned into a snap-fit fit, the flow rate can be increased or decreased by the screw, and the influence of internal pressure is eliminated in the flow rate regulation control, so that the stability of glue output is guaranteed when the glue amount is adjusted, and the accuracy of glue amount adjustment is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 A side cross-sectional view of the device. DETAILED DESCRIPTION
[0011] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.
[0012] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0013] like Figure 1 As shown, a flow regulating valve for a blank head includes a valve body 1, an adjusting rod 2, a screw 3 and a threaded sleeve 4; the valve body is provided with a stepped hole, and the adjusting rod, the screw and the threaded sleeve are all installed in the stepped hole. Specifically, the threaded sleeve is embedded in one end of the stepped hole, and the threaded sleeve is pressed into the stepped hole by means of an interference connection. One end of the threaded sleeve has a thread 5, which is used to cooperate with the screw thread, and the other end of the threaded sleeve has a guide groove 6, and the right end of the adjusting rod is slidably matched with the guide groove. The right end of the adjusting rod is designed to be square, or other shapes, and can slide in the guide groove.
[0014] In order to ensure that the screw can be rotated while the adjusting rod cannot be rotated, so that the adjusting rod can only move left and right, a T-shaped slot 7 is provided at the right end of the adjusting rod, one end of the screw is connected to the T-shaped slot, and the left end of the screw is designed as a T-shaped cap structure, which is inserted into the T-shaped slot and can be rotated in the T-shaped slot. The rod body of the screw is threadedly connected to the threaded sleeve, and the screw is rotated, and the screw moves left and right in the threaded sleeve, thereby driving the adjusting rod to slide left and right in the guide groove. The valve body is provided with a glue nozzle 8, and the left end of the adjusting rod is inserted from the side of the glue nozzle to adjust the flow rate of the glue nozzle.
[0015] When in use, first screw the screw into the threaded sleeve, then insert one end of the screw into the T-slot from the side of the adjusting rod, then align the adjusting rod with the through hole on the valve body, pass the adjusting rod through the through hole to the position of the glue outlet nozzle, and finally press the threaded sleeve into the stepped hole to complete the overall assembly. When in use, use an Allen wrench to turn the screw to adjust the position of the adjusting rod at the glue outlet nozzle, similar to a faucet. If the adjusting rod fills the glue outlet nozzle completely, the flow rate of glue in the glue outlet nozzle will decrease, otherwise it will increase.
[0016] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
