Description

Technical Field

[0001] This utility model relates to the field of plastic pipe processing technology, specifically to a pipe unloading device for a plastic pipe cutting machine. Background Technology

[0002] Plastic pipes are generally made from synthetic resin, namely polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and are processed by extrusion in a pipe-making machine using a "plastic" method. They are mainly used for piping in water supply systems, drainage, ventilation, and sewage systems in buildings, underground drainage systems, rainwater pipes, and conduits for electrical wiring installations, etc., and require cutting operations during processing.

[0003] The utility model disclosed in CN203600322U is a pipe unloading device for a plastic pipe cutting machine, including a bracket, a baffle plate disposed on the bracket, and a support plate for supporting plastic pipes. One end of the support plate near the plastic pipe cutting machine is the front end, and the other end is the tail end. One side of the support plate is fixedly connected to the lower side of the baffle plate.

[0004] The aforementioned application document describes a method where the position of the stop is reasonably set so that after the cut plastic pipe contacts the stop, it slides out of the support plate away from the stop by its own weight under the action of the stop, thus completing the pipe unloading work. However, the surface of the cut plastic pipe is usually covered with a large amount of debris and dust, which can easily float into the air and pollute the environment during pipe unloading and subsequent transportation, affecting the subsequent processing work. Therefore, this method needs to be improved. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a pipe unloading device for a plastic pipe cutting machine, which solves the technical problem that the pipes are easily floated into the air and pollute the environment during the unloading and subsequent transportation process in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a pipe unloading device for a plastic pipe cutting machine, comprising: a base and a conveyor belt; a discharge plate and a machine body are fixedly connected to the top of the base; a drive shaft and a driven roller are rotatably connected to the inner side of the machine body; a drive roller is fixedly connected to the surface of the drive shaft; the driven roller is driven by the conveyor belt; a motor is fixedly installed at the front end of the machine body; and a cleaning mechanism and a brushing mechanism are provided at the front end of the machine body; the cleaning mechanism includes a drive gear, a rotating rod, a piston cylinder, a diverter box, and a water tank; the drive gear is fixedly connected to the surface of the drive shaft. The rotating rod is rotatably connected to the front end of the machine body. A driven gear is fixedly connected to the surface of the rotating rod. A pressing block is fixedly connected to the front end of the rotating rod. The piston cylinder and the water tank are both fixedly connected to the front end of the machine body. A return spring is installed inside the piston cylinder. A piston rod is slidably connected to the piston cylinder through the return spring. A water inlet pipe is passed through and fixedly connected to the side of the piston cylinder. A water delivery pipe is passed through and fixedly connected to the top of the piston cylinder. A one-way valve is installed inside both the water inlet pipe and the water delivery pipe. The diversion box is fixedly connected to the top of the machine body. A nozzle is installed at the bottom of the diversion box.

[0007] For example, in at least one embodiment of the present invention, a pipe unloading device for a plastic pipe cutting machine further includes: the output shaft of the motor is fixedly connected to the drive shaft, the conveyor belt is hollowed out, and a wastewater tank is provided on the top of the base. When the motor is turned on, the drive shaft can be driven to rotate, and the cleaning water can fall into the wastewater tank through the conveyor belt.

[0008] The driving gear meshes with the driven gear, and the diameter of the driving gear is larger than the diameter of the driven gear. The rotation of the driving gear drives the driven gear to rotate; the larger diameter of the driving gear results in more rotations of the driven gear.

[0009] The end of the piston rod away from the return spring is close to the compression block, and a ball bearing is provided at the end of the piston rod away from the return spring. When the compression block rotates with the rotating rod, it will repeatedly compress the ball bearing, causing the piston rod to move to the right.

[0010] The one-way valve inside the water inlet pipe is designed to allow one-way flow into the piston cylinder. The end of the water inlet pipe away from the piston cylinder is connected to the water tank in a fixed manner. When a negative pressure is formed inside the piston cylinder, the water inlet pipe will draw cleaning water from the water tank.

[0011] The end of the water supply pipe away from the piston cylinder is connected to the diversion box through and fixedly connected. The one-way valve inside the water supply pipe is unidirectionally open towards the diversion box. When the piston cylinder is squeezed, the cleaning water inside will be transported to the diversion box through the water supply pipe.

[0012] The number of nozzles is set to five groups, and the five groups of nozzles are evenly distributed at the bottom of the flow distribution box.

[0013] According to another aspect, at least one embodiment of the present invention also provides a brushing mechanism, including: a pressure chamber, the pressure chamber being connected through and fixedly connected to the front end of the machine body, an air bladder being provided at one end of the pressure chamber, a push rod being slidably connected to a piston inside the other end of the pressure chamber, and a brush head being fixedly connected to the end of the push rod away from the pressure chamber.

[0014] For example, in at least one embodiment of the present invention, a pipe unloading device for a plastic pipe cutting machine further includes: the airbag is initially in an inflated state, and the end of the airbag away from the air pressure chamber is close to the extrusion block, and the extrusion block will repeatedly extrude the airbag when it rotates with the rotating rod.

[0015] The brush head is square in shape, and the bristles of the brush head are in contact with the bottom of the conveyor belt. When the brush head moves back and forth, its bristles will scrub the conveyor belt.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] This invention incorporates a cleaning mechanism that, when the cut plastic pipes fall onto the unloading plate and roll onto the conveyor belt for transport, the water inlet pipe draws cleaning water from the water tank through the cooperation of components such as the drive gear, driven gear, extrusion block, and piston rod. The water is then transported to the distribution box via the water supply pipe and finally sprayed out by the nozzle to clean the cut plastic pipes. This prevents the waste chips and dust generated during cutting from flying into the air and affecting the environment during transportation, and also facilitates the subsequent processing of the plastic pipes.

[0018] This invention incorporates a brushing mechanism, which, in conjunction with components such as airbags and air chambers, drives the brush head to move back and forth to brush the conveyor belt while transporting plastic pipes. This prevents waste chips and dust generated during plastic pipe cutting from adhering to the conveyor belt during transportation, effectively ensuring the overall cleanliness of the conveyor belt.

[0032] like Figures 1-5 The diagram illustrates a pipe unloading device for a plastic pipe cutting machine according to an embodiment of the present invention. The device includes: a base 1 and a conveyor belt 8. A discharge plate 2 and a machine body 3 are fixedly connected to the top of the base 1. A drive shaft 4 and a driven roller 6 are rotatably connected to the inner side of the machine body 3. A drive roller 5 is fixedly connected to the surface of the drive shaft 4. The driven roller 6 is connected to the driven roller 6 via the conveyor belt 8. A motor 7 is fixedly installed at the front end of the machine body 3. A cleaning mechanism 9 and a brushing mechanism 10 are provided at the front end of the machine body 3. The cleaning mechanism 9 includes a drive gear 91, a rotating rod 92, a piston cylinder 95, a diverter box 911, and a water tank 913. The drive gear 91 is fixedly connected to the surface of the drive shaft 4. The rotating rod 92 rotates... The rotating rod 92 is fixedly connected to the front end of the machine body 3. A driven gear 93 is fixedly connected to the surface of the rotating rod 92. A squeezing block 94 is fixedly connected to the front end of the rotating rod 92. The piston cylinder 95 and the water tank 913 are both fixedly connected to the front end of the machine body 3. A return spring 96 is installed inside the piston cylinder 95. A piston rod 97 is slidably connected to the piston inside the piston cylinder 95 through the return spring 96. A water inlet pipe 99 is fixedly connected through the side of the piston cylinder 95. A water delivery pipe 910 is fixedly connected through the top of the piston cylinder 95. A one-way valve is installed inside both the water inlet pipe 99 and the water delivery pipe 910. A diversion box 911 is fixedly connected to the top of the machine body 3. A nozzle 912 is installed at the bottom of the diversion box 911.

[0033] In some examples, the output shaft of the motor 7 is fixedly connected to the drive shaft 4, the conveyor belt 8 is hollow, and the top of the base 1 is provided with a wastewater tank 11. When the motor 7 is turned on, the drive shaft 4 can be driven to rotate, and the cleaning water can fall into the wastewater tank 11 through the conveyor belt 8.

[0034] The driving gear 91 meshes with the driven gear 93, and the diameter of the driving gear 91 is larger than the diameter of the driven gear 93. The rotation of the driving gear 91 can drive the driven gear 93 to rotate, and the larger diameter of the driving gear 91 drives the driven gear 93 to rotate more times.

[0035] The end of the piston rod 97 away from the return spring 96 is close to the pressing block 94, and a ball bearing 98 is provided at the end of the piston rod 97 away from the return spring 96. When the pressing block 94 rotates with the rotating rod 92, it will repeatedly press the ball bearing 98, causing the piston rod 97 to move to the right.

[0036] The one-way valve inside the water inlet pipe 99 is for one-way flow towards the inside of the piston cylinder 95, and the end of the water inlet pipe 99 away from the piston cylinder 95 is connected to the water tank 913 through and fixedly connected. When a negative pressure is formed inside the piston cylinder 95, the water in the water tank 913 will be drawn through the water inlet pipe 99 to clean the water.

[0037] The end of the water supply pipe 910 away from the piston cylinder 95 is connected to the diversion box 911 through and fixedly connected. The one-way valve in the water supply pipe 910 is unidirectionally open towards the diversion box 911. When the piston cylinder 95 is squeezed, the cleaning water inside it will be transported to the diversion box 911 through the water supply pipe 910.

[0038] The number of nozzles 912 is set to five groups, and the five groups of nozzles 912 are evenly distributed at the bottom of the flow distribution box 911.

[0039] For example, such as Figures 1-5As shown, the entire device is installed next to the cutting machine. The plastic pipes cut by the cutting machine roll off the unloading plate 2 onto the conveyor belt 8 for unloading. Then, the motor 7 can be turned on to drive the drive shaft 4 to rotate. The drive shaft 4 rotates, which in turn drives the drive roller 5 to rotate. The drive roller 5, in conjunction with the driven roller 6, drives the conveyor belt 8 to transport the pipes. The rotation of the drive shaft 4 drives the drive gear 91 to rotate, which in turn drives the driven gear 93 to rotate. The driven gear 93 rotates more frequently, and its rapid rotation drives the rotating rod 92 to rotate rapidly. The rotating rod 92 then drives the extrusion block 94 to rotate. As the extrusion block 94 rotates with the rotating rod 92, it repeatedly squeezes the ball bearing 98, causing it to move. When the piston rod 97 moves to the right, the return spring 96 is compressed. The movement of the piston rod 97 to the right will squeeze the cleaning water in the piston cylinder 95, causing it to be transported through the water supply pipe 910 to the distribution box 911, and finally sprayed out by the nozzle 912. When the squeezing block 94 leaves the ball 98, the return spring 96 rebounds and drives the piston rod 97 to move to the left to restore its original position. At this time, a negative pressure is formed in the piston cylinder 95, which will draw the cleaning water in the water tank 913 through the water inlet pipe 99 to replenish it. This cycle continues, and the cleaning water sprayed out by the nozzle 912 cleans the cut plastic pipe, preventing the waste chips and dust generated during cutting from flying into the air and affecting the environment during transportation. It also facilitates the subsequent processing of the plastic pipe.

[0040] like Figures 1-5 As shown, a brushing mechanism 10 in another embodiment of the present invention is shown, including: an air pressure chamber 101, which is connected through and fixedly connected to the front end of the body 3. An air bag 102 is provided at one end of the air pressure chamber 101, and a push rod 103 is slidably connected to the piston inside the other end of the air pressure chamber 101. A brush head 104 is fixedly connected to the end of the push rod 103 away from the air pressure chamber 101.

[0041] In some examples, the airbag 102 is initially inflated, and the end of the airbag 102 away from the air chamber 101 is close to the compression block 94. The compression block 94 will repeatedly compress the airbag 102 as it rotates with the rotating rod 92.

[0042] The brush head 104 is square in shape, and the bristles of the brush head 104 are in contact with the bottom of the conveyor belt 8. When the brush head 104 moves back and forth, its bristles will brush the conveyor belt 8.

[0043] For example, such as Figures 1-5As shown, when the squeezing block 94 rotates with the rotating rod 92, it repeatedly squeezes the airbag 102. When the airbag 102 is squeezed, the air pressure inside it enters the air pressure chamber 101 and pushes the push rod 103 to move to the rear end. The push rod 103 moving to the rear end will drive the brush head 104 to move to the rear end. When the squeezing block 94 leaves the airbag 102, the airbag 102 rebounds due to its elasticity, and the air pressure in the air pressure chamber 101 returns to the airbag 102. At the same time, the air pressure drives the push rod 103 to move to the front end to return to its original position. The brush head 104 moves back and forth to clean the conveyor belt 8, preventing waste chips and dust generated from cutting plastic pipes from adhering to the conveyor belt 8 during transportation, effectively ensuring the overall cleanliness of the conveyor belt 8.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
