Description

Technical Field

[0001] This utility model belongs to the field of fire extinguisher siphon tube processing technology, specifically relating to a tube screwing machine. Background Technology

[0002] In the processing of the siphon tube of a fire extinguisher, the screwing process is a crucial step. However, existing methods have the following shortcomings: ① Errors in the length of the siphon tube can lead to inconsistent screwing depths; ②The siphon tube itself may have poor straightness, which will affect the material discharge. To address this, we propose a pipe-twisting machine for processing fire extinguisher siphon tubes. On the one hand, the adjustable feeding rack can accommodate fire extinguisher siphon tubes of different lengths. On the other hand, the design of the feeding and shaping mechanisms reduces the impact of poor material straightness on the output, minimizing errors. Summary of the Invention

The feeding rack includes: a horizontal support, with a first mounting platform fixed to one side and a first slide table slidably connected to the other side; a fixed guide frame, which is fixedly mounted to the first mounting platform; a movable guide frame, which is fixedly mounted to the first slide table; both the fixed guide frame and the movable guide frame are inclined structures from rear to front and from top to bottom; a front panel, one side of which is fixedly mounted to the front side of the fixed guide frame, and the front panel has several horizontal adjustment slots, with the movable guide frame locked to the horizontal adjustment slots by bolts; the feeding mechanism corresponds to the lower end of the feeding rack, and a guide plate is mounted between the feeding mechanism and the shaping mechanism.

[0005] As a further limitation of the present invention, the feeding rack also includes a guide frame that slopes from the rear to the front and from top to bottom. A second slide is slidably connected to the middle of the transverse support. The guide frame and the second slide are fixed together, and the second slide is locked to the transverse support by bolts.

[0006] As a further limitation of the present utility model, the lower sides of the fixed guide frame and the movable guide frame facing each other are also provided with limiting components.

Detailed Implementation

[0013] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0014] like Figures 1 to 3 The pipe tightening machine shown includes a machine base 100, which is equipped with a feeding rack 110, a feeding mechanism 120, and a shaping mechanism 130. The feeding rack 110 includes: a horizontal support 111, on one side of which a first mounting platform 1111 is fixed and on the other side of which a first slide table 1112 is slidably connected; a fixed guide frame 112, which is fixedly mounted to the first mounting platform 1111; a movable guide frame 113, which is fixedly mounted to the first slide table 1111; both the fixed guide frame 112 and the movable guide frame 113 are inclined structures from the rear to the front and from top to bottom; and a front panel 114, on one side of which is fixedly mounted to the front of the fixed guide frame 112. The front panel 114 has several horizontal adjustment slots 1141, and the movable guide frame 113 is locked to the horizontal adjustment slots 1141 by bolts. The feeding mechanism 120 corresponds to the lower end of the unloading rack 110, and a guide plate 140 is provided between the feeding mechanism 120 and the shaping mechanism 130.

[0015] As can be seen from the structure of the feeding rack 110, the first mounting platform 1111 is fixed to the transverse support 111, and the fixed guide frame 112 is fixed to the first mounting platform 1111. At the same time, the front panel 114 is fixed to the fixed guide frame 112. Therefore, the front panel 114 can be in a fixed state of being suspended. Before the fire extinguisher siphon tube is dispensed, the movable guide frame 113 of the feeding rack 110 is adjusted and assembled according to the length of the fire extinguisher siphon tube. The specific adjustment steps are as follows: ① The first slide table 1112 of the sliding horizontal support 111 causes the movable guide frame 113 fixed to the first slide table 1112 to move laterally. At this time, the movable guide frame 113 can move laterally relative to the front panel 114. ② After the distance between the movable guide frame 113 and the fixed guide frame 112 matches the length of the fire extinguisher siphon tube, multiple bolts are inserted between the movable guide frame 113 and the front panel 114 to lock it in place. Bolt fixing is a common existing fixing method, which will not be described in detail here. In this way, the discharge rack 110 can be adjusted to match the length of the fire extinguisher siphon tube, so that it can be used for screwing fire extinguisher siphon tubes of various lengths during operation.

[0016] Furthermore, in order to support the middle of the fire extinguisher siphon tube in the discharge rack 110 and prevent the fire extinguisher siphon tube from bending downwards in the middle due to gravity, the following improvements are made, such as... Figure 2 and Figure 3 As shown, the feeding rack 110 also includes a guide frame 115 that slopes from the rear to the front and from top to bottom. A second slide table 1113 is slidably connected to the middle of the transverse support 111. The guide frame 115 and the second slide table 1113 are fixed together and locked together by bolts.

[0017] Since the length of the discharge rack 110 is adjustable, the following operations can be performed to accommodate the support of the middle section of fire extinguisher siphon tubes of different lengths: First, according to the adjustable length of the feeding rack 110, the second slide 1113 is slid relative to the transverse support 111, so that the guide frame 115 mounted on the second slide 1113 is in the middle of the length of the feeding rack 110. Then, the second slide 1113 is fixed to the transverse support 111 by locking bolts. In this way, the position of the guide frame 115 can be dynamically adjusted to achieve the middle support effect of fire extinguisher siphon tubes of different lengths. The bolt fixing between the second slide 1113 and the transverse support 111 is a common existing fixing method, which will not be described in detail here.

[0018] Furthermore, in order to control the feeding of the fire extinguisher siphon tube in the feeding rack 110 and ensure orderly feeding, the following improvements are made: Figure 2As shown, the fixed guide frame 112 and the movable guide frame 113 are both provided with limiting components on their lower sides facing each other. Both limiting components include guide wheels 116 and limiting frames 117. The two sets of guide wheels 116 have feeding gaps with the lower side of the fixed guide frame 112 and the lower side of the movable guide frame 113, respectively. The bottom of the two limiting frames 117 also has feeding gaps with the lower side of the fixed guide frame 112 and the lower side of the movable guide frame 113.

[0019] To ensure orderly feeding of the fire extinguisher siphon tubes in the feeding rack 110, guide wheels 116 and limiting frames 117 are used. By having feeding gaps between the two sets of guide wheels 116 and the lower sides of the fixed guide frame 112 and the movable guide frame 113, respectively, and by having feeding gaps between the bottom of the two limiting frames 117 and the lower sides of the fixed guide frame 112 and the movable guide frame 113, the fire extinguisher siphon tubes can be fed one tube at a time, effectively avoiding disorderly and excessive feeding. Example

[0020] This embodiment is a detailed description of the structure of the feeding mechanism based on Embodiment 1, such as... Figure 3 and Figure 4 As shown, the feeding mechanism 120 includes: a feeding motor 121, which is installed on one side of the machine base 100, and the output end of the feeding motor 121 is provided with a rotating shaft 1211; a plurality of feeding trays 122, each feeding tray 122 is fixedly installed with the rotating shaft 1211, and each feeding tray 122 is provided with a plurality of clamping grooves 1221; a plurality of positioning frames 123, which are fixedly mounted on the machine base 100 and are provided with guide grooves 1231 that match the feeding trays 122, the rear end of the guide grooves 1231 corresponds to the lower end of the feeding rack 110, and the front end of the guide grooves 1231 corresponds to the guide plate 140.

[0021] During single-tube feeding, the fire extinguisher siphon tube can enter the clamping groove 1221 of the feeding tray 122 through the guide groove 1231 of the positioning frame 123, thereby allowing multiple feeding trays 122 to clamp the fire extinguisher siphon tube in multiple segments through their clamping grooves 1221. The feeding motor 121 here is a low-speed motor to control the feeding speed so as not to be too fast. Meanwhile, Figure 4 As shown, the guide groove 1231 has an arc-shaped section to keep it stable when the feeding plate 122 drives the fire extinguisher siphon tube to rotate and feed. This allows the fire extinguisher siphon tube to be fed out in an orderly manner through the feeding mechanism 120, and finally fed out through the front end of the guide groove 1231 to the guide plate 140, from which the guide plate 140 guides the fire extinguisher siphon tube to the shaping mechanism 130. Example

[0022] This embodiment is based on Embodiment 2 and provides a detailed description of the structure of the shaping mechanism, such as... Figure 3 and Figure 5 As shown, the shaping mechanism 130 includes: two shaping rotating rods 131, which are rotatably mounted on the machine base 100 and correspond to the lower end of the guide plate 140. The machine base 100 has a built-in drive component for driving the two shaping rotating rods 131 to rotate; two sets of first shaping rollers 132, which are respectively installed and fixed to the two shaping rotating rods 131; a mounting frame 133, which is installed and fixed to the machine base 100; a pneumatic telescopic rod 134, which is installed and fixed to the mounting frame 133; and a second shaping roller 135, which is rotatably mounted on the pneumatic telescopic rod 134 and is located above the two sets of first shaping rollers 133.

[0023] Before the fire extinguisher siphon tube is fed into the shaping mechanism 130 by the guide plate 140, the pneumatic telescopic rod 134 drives the second shaping roller 135 to move upward. After the fire extinguisher siphon tube is fed into the shaping mechanism 130 by the guide plate 140, the fire extinguisher siphon tube is between the two shaping rotating rods 131. The pneumatic telescopic rod 134 then drives the second shaping roller 135 to move downward. Through the combined action of the two sets of first shaping rollers 132 and second shaping rollers 135, the fire extinguisher siphon tube is flattened, so that the fire extinguisher siphon tube can remain straight during the pipe tightening operation. Furthermore, during the process of the fire extinguisher siphon tube being flattened by the two sets of first shaping rollers 132 and second shaping rollers 135, the drive component built into the machine 100 drives the two shaping rotating rods 131 to rotate. Specifically, the two shaping rotating rods 131 rotate in the same direction, so that the fire extinguisher siphon tube can rotate in one direction through the rotation of the two first shaping rollers 132. People can then align the siphon tube head with the connection point of the siphon tube and screw the fire extinguisher siphon tube into the siphon tube head.

[0024] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
