[0001] This utility model relates to the field of PVC pipe technology, specifically a PVC pipe joint trimming machine. Background Technology

[0002] PVC pipe, also known as polyvinyl chloride pipe, is a plastic product made from polyvinyl chloride resin as the main raw material, with the addition of stabilizers, lubricants, fillers, colorants and other auxiliary materials, through processes such as hot mixing and extrusion molding. The joints at both ends of the finished PVC pipe are uneven and need to be polished with an edge trimming machine to make the PVC pipe better connected and used.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] However, when existing PVC pipe trimming machines grind the joints, the waste material from the pipes forms dust particles after the grinding disc of the trimming machine grinds the joints flat. At the same time, the airflow generated when the grinding disc rotates will carry the dust particles into the external environment, thus causing pollution to the external environment.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a PVC pipe joint trimming machine to solve the problems mentioned in the background art.

[0007] By adopting the above technical solution, the dust collection hopper and dust cover are used to prevent dust from spreading to the end of the pipe to be ground, thus solving the problem of waste material from the pipe causing environmental pollution when the grinder grinds the joint of the pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a PVC pipe joint trimming machine.

[0024] Please see Figures 1-5 A PVC pipe joint trimming machine includes a base 1. A dust collection hopper 101 is fixedly installed on one side of the top of the base 1. A dust cover 102 is movably installed on the top of the dust collection hopper 101. The bottom of the inner wall of the dust collection hopper 101 is conical. A round hole 103 is opened on the other side of the dust collection hopper 101 and the dust cover 102 that are close to each other. A discharge port 104 that is connected to the dust collection hopper 101 is opened inside one side of the base 1. A discharge hopper 105 located at the bottom of the discharge port 104 is fixedly installed at the bottom of one side of the base 1.

[0025] With the above-described structural design, the PVC pipe joint trimming machine extends the pipe joint to be trimmed through the round hole 103 into the dust collection hopper 101 and the dust cover 102. The trimming machine trims the joint of the pipe joint. When the trimming disc grinds the pipe, the dust generated by the grinding waste is protected by the dust cover 102 and the round hole 103. Since the bottom of the dust collection hopper 101 is conical, the falling dust is discharged and collected through the discharge port 104 and the discharge hopper 105, thus avoiding the formation of dust from the pipe joint and causing environmental pollution when the grinder grinds the joint.

[0026] Furthermore, an electric telescopic rod 106 is fixedly installed through one side of the dust cover 102, and a pipe joint trimming device 107 located inside the dust cover 102 is fixedly installed at the output end of the electric telescopic rod 106. When the end of the pipe to be trimmed extends into the dust collection hopper 101 and the dust cover 102, the output end of the electric telescopic rod 106 extends or retracts, causing the pipe joint trimming device 107 to perform trimming and smoothing operations on the pipe joint inside the dust collection hopper 101 and the dust cover 102, facilitating automatic trimming of the pipe.

[0027] Furthermore, a servo motor 108 is fixedly installed on the top of one side of the base 1, located on one side of the dust collection hopper 101. A first lead screw 109 is fixedly installed at the output end of the servo motor 108, and a first threaded collar 110, which is fixedly connected to the dust cover 102, is sleeved on the outer side of the first lead screw 109. The output of the servo motor 108 drives the first lead screw 109 to rotate, causing the first threaded collar 110 to move upward on the outer side of the first lead screw 109, thereby driving the dust cover 102 to move upward and open, facilitating the cleaning of the inner walls of the dust collection hopper 101 and the dust cover 102 by the staff, and preventing the pipe dust particles from adhering to the inner walls of the dust collection hopper 101 and the dust cover 102.

[0028] Furthermore, a support frame 2 is fixedly installed on one side of the top of the base 1. The front and rear ends of the inner side of the support frame 2 are provided with sliding grooves 201. A slider 202, which is fixedly connected to the dust cover 102, is slidably installed inside the sliding grooves 201. When the dust cover 102 moves upward and rises, the slider 202 slides inside the sliding grooves 201, so that the dust cover 102 does not shake when it moves, thus improving the stability of the device.

[0029] Furthermore, pipe brackets 3 are fixedly installed on both sides of the top of the base 1. A clamping plate 301 is movably installed at the front end of the top of the pipe bracket 3. A second threaded rod 302 extending to the front end is rotatably installed inside the pipe bracket 3. A through groove 303 is opened through the top of the pipe bracket 3. A second threaded collar 304 is fixedly connected to the bottom of the clamping plate 301 by threaded connection to the outside of the second threaded rod 302 through the through groove 303. In this way, by placing the pipe on the top of the pipe bracket 3 and then rotating the second threaded rod 302, the second threaded collar 304 moves to the rear end of the outside of the second threaded rod 302, thereby driving the clamping plate 301 to move to the rear end to clamp and fix the pipe, which facilitates more stable trimming operations at the joint of the pipe.

[0030] Furthermore, a rubber pad 305 is fixedly installed on the inner side of the rear end of the pipe bracket 3. The surface of the rubber pad 305 is evenly distributed with anti-slip texture. When the pipe bracket 3 and the clamping plate 301 clamp and fix the pipe, the rubber pad 305 contacts the surface of the pipe, preventing the surface of the pipe from being scratched by the pipe bracket 3 and the clamping plate 301 during trimming. At the same time, because the surface of the rubber pad 305 is distributed with anti-slip texture, the friction of the contact surface of the pipe is increased, thereby making the pipe clamped and fixed more firmly.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
