Description

Technical Field

[0001] The utility model relates to the technical field of fixed-length cutting, in particular to a fixed-length device and PVC pipe cutting equipment thereof. Background Art

[0002] During the processing of PVC pipes, in order to make the length of the pipes meet the usage requirements, the PVC pipes need to be cut by cutting equipment to obtain finished PVC pipes with a specified length.

[0003] In the prior art, in order to facilitate the control of the cutting length of PVC pipes, many pipe cutting equipment are now equipped with a fixed length device, which limits the length of the PVC pipe extension. For example, the utility model patent with authorization announcement number CN217597175U discloses a fixed length pipe cutting device. In this patent, the fixed length of a single pipe cutting is achieved by cooperating with a blocking rod and a guide rod, which not only determines the cutting length of the pipe, but also facilitates the fixed length.

[0004] However, the above patent has the following problems in actual use: in actual use, after the guide rod and the material stop rod cooperate to block the pipe to complete the fixed-length cutting, since the guide rod and the material stop rod cannot move to release the restriction on the pipe blocking, the subsequent pipe cannot move forward to push away the previously cut pipe, resulting in the inability to directly load the subsequent pipe. The pipe blocked by the material stop rod needs to be manually moved away before loading can continue. This not only requires increased labor costs to remove the cut pipes, but also affects the work efficiency of subsequent pipe cutting. For this reason, a fixed-length device and its PVC pipe cutting equipment are proposed. Utility Model Content

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1. The present utility model provides a fixed-length device as Figures 1-4 shown, which includes a fixed-length mechanism 200 and a mounting base 100 disposed below the fixed-length mechanism 200. The fixed-length mechanism 200 is used for fixed-length blocking of PVC pipes. A deflection mechanism 300 is provided between the mounting base 100 and the fixed-length mechanism 200, and the deflection mechanism 300 is used to drive the fixed-length mechanism 200 to deflect;

[0024] In the above embodiment, the mounting base 100 is configured with settlement holes or other auxiliary structures that meet the installation requirements, which can fixedly install the mounting base 100 on the frame of the PVC pipe cutting equipment, so that the blocking end of the fixed-length mechanism 200 can be located in front of the forward movement direction during the cutting of the PVC pipe. Thus, the specific position of the blocking end on the fixed-length mechanism 200 can be used to block the end of the PVC pipe to achieve the purpose of fixed-length cutting. After the cutting of the fixed-length PVC pipe is completed, only need to drive the fixed-length mechanism 200 to deflect and rotate above the mounting base 100 through the deflection mechanism 300, so that the fixed-length mechanism 200 removes the blocking of the PVC pipe end face, and the subsequent cut PVC pipe can be pushed out by the forward movement to push out the PVC pipes in front and the completed cut PVC pipes. Therefore, there is no need to manually carry the PVC pipes after cutting, which reduces the working intensity and helps to improve the working efficiency.

[0025] Among them, the deflection mechanism 300 includes a connecting shaft 302 fixedly arranged above the mounting base 100. An external wall of the connecting shaft 302 is provided with an incomplete gear 301 that can rotate around the connecting shaft 302. A side wall of the incomplete gear 301 is fixedly arranged with the fixed-length mechanism 200. A top end of the mounting base 100 is provided with a rack plate 303 that can translate along the top end of the mounting base 100. A top of the rack plate 303 is meshed and connected with a bottom of the incomplete gear 301. And an electric push rod 305 for driving the rack plate 303 to translate is arranged at the top end of the mounting base 100. By controlling the telescopic movement of the electric push rod 305 after being powered on, the rack plate 303 can be driven to translate. While the rack plate 303 is translating, it can drive the incomplete gear 301 to rotate. Since the incomplete gear 301 is relatively fixed to the fixed-length mechanism 200, the fixed-length mechanism 200 is deflected. At the same time, only by retracting and resetting the electric push rod 305 can the fixed-length mechanism 200 be driven to rotate and reset. The operation is simple and convenient. It should be noted that both the rack plate 303 and the incomplete gear 301 are in two groups and are symmetrically arranged above the mounting base 100. A fixing rod 306 is fixedly connected between the two rack plates 303. One end of the electric push rod 305 is fixedly connected to the middle of the fixing rod 306, so as to synchronously drive both ends of the fixed-length mechanism 200 to deflect synchronously. In this way, the stability of the deflection process of the fixed-length mechanism 200 can be ensured. A linear slide rail 304 is fixedly connected to the top end of the mounting base 100. A bottom of the rack plate 303 is movably sleeved on an external wall of the linear slide rail 304. The arrangement of the linear slide rail 304 can play a role in limiting and guiding the translation of the rack plate 303, and enhance the stability of the movement of the rack plate 303. A baffle 307 is fixedly connected to a side of the top end of the mounting base 100 away from the electric push rod 305. The baffle 307 is used for the auxiliary support of the fixed-length mechanism 200. The baffle 307 can prevent the end of the fixed-length mechanism 200 from being placed in a suspended state, thereby enhancing the stability of the fixed-length mechanism 200 when it is placed and used.

[0026] Furthermore, the fixed length mechanism 200 includes an outer shell 201, and a blocking member 206 is movably provided on one side of the outer shell 201. In a preferred embodiment, the blocking member 206 includes a bottom plate 261 fixedly connected to one end of the connecting block 205, a side plate 262 is fixedly connected to one side of the bottom plate 261, and a triangular plate 263 is fixedly connected to both sides of the side plate 262 and the bottom plate 261. By adding the triangular plate 263 between the bottom plate 261 and the side plate 262 in the blocking member 206, the overall stability of the blocking member 206 can be enhanced; the incomplete gear 301 is fixedly arranged on the outer shell 201 away from the On one side of the blocking member 206, a rotatable driving screw 203 is provided inside the outer shell 201, and the outer wall of the driving screw 203 is threadedly connected to the moving seat 202. A servo motor can be configured outside the outer shell 201 to control the clockwise or counterclockwise rotation of the driving screw 203, so as to achieve electric control of the movement of the blocking member 206. A linear slide bar 204 movably plugged with the moving seat 202 is fixedly connected inside the outer shell 201, and a connecting block 205 is fixedly connected to the outer wall of the moving seat 202. One end of the connecting block 205 extends to the outside of the outer shell 201 and is fixedly connected to the blocking member 206.

[0027] When the fixed-length mechanism 200 is in use, it only needs to drive the driving screw 203 to rotate clockwise or counterclockwise through an external driving device (servo motor), and cooperate with the linear slide 204 to guide the movement of the movable seat 202, so that the driving screw 203 drives the movable seat 202 to translate along the linear slide 204 when rotating, thereby adjusting the position of the blocking member 206 on the side wall of the outer shell 201 and locking the position of the blocking member 206. The cutting length can be adjusted by changing the distance between the blocking member 206 and the cutter in the pipe cutting equipment. With the blocking member 206 blocking the forward movement of the PVC pipe, the fixed-length operation of cutting the PVC pipe can be achieved.

[0028] Embodiment 2: The utility model further provides a PVC pipe cutting device, which includes the length-fixing device in Embodiment 1.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
