Description

Technical Field

[0001] The invention relates to the technical field of floor heating pipe processing, and in particular to a PE-RT floor heating pipe processing and cutting device. Background Art

[0002] PE-RT floor heating pipes need to be cut during processing. During the cutting process, workers usually stand opposite the cutting machine and face the cutting disc directly. There is no direct protective device. Once there is a problem with the machine, it may cause injury to the workers.

[0003] Chinese patent CN217044814U discloses a cutting device based on floor heating pipes for heating, including a cutting machine body, a material rack is fixedly connected to the front of the cutting machine body, a feed rack is fixedly connected to the back of the cutting machine body, and the material rack and the feed rack are used in conjunction with each other, a baffle is arranged on the right side of the top of the cutting machine body, a first slider is symmetrically fixedly connected to the bottom of the baffle, a first slide groove is opened on the left side of the top of the cutting machine body, the bottom of the first slider extends to the inside of the first slide groove and contacts with the bottom of the inner wall of the first slide groove, a concave block is arranged on the top of the baffle, and the top of the baffle extends to the inside of the concave block, a mounting hole is opened inside the baffle, and A pressure plate is provided inside the mounting hole, and the left end of the pressure plate passes through the mounting hole and extends to the left side of the baffle, a positioning plate is fixedly connected to the left side of the bottom of the pressure plate, limiting holes are provided on the left and right sides of the concave block, the limiting holes are communicated with the mounting hole, and both ends of the pressure plate pass through the limiting holes, and the top of the pressure plate is fixedly connected to the top of the inner wall of the limiting hole, a mounting groove is provided on the top of the baffle, a spring is provided inside the baffle, and the bottom of the spring is fixedly connected to the bottom of the mounting groove, the top of the spring is fixedly connected to the limiting plate, the top of the limiting plate is fixedly connected to a connecting rod, the top of the connecting rod passes through the mounting groove and extends to the top of the baffle and is fixedly connected to the top of the inner wall of the concave block.

[0004] Although the above scheme improves the protection effect, it still requires workers to operate close to the blade, so there is still a risk to the hands. When cutting PERT floor heating pipes, since PERT pipes are made of polyethylene material, polyethylene particles will splash during cutting. Since polyethylene material is light in texture, it is difficult to clean after processing. In actual cutting, workers are required to measure the length of the pipe and cut it by themselves, and the accuracy is low. Even if a machine is used for automatic cutting, most of the existing cutting devices are characterized by the tool not moving and the limit unit moving. In this way, there is no reserved place for the knife groove at the bottom of the tool. When the limit unit pushes the floor heating pipe to move, the limit unit is easily accidentally cut by the knife when it cuts. Summary of the invention

[0005] In view of the above problems, a PE-RT floor heating pipe processing and cutting equipment is provided. First, the pipe needs to be placed on the upper part of the support belt along the length direction of the base. The pipe located on the upper part of the support belt passes horizontally through the cutting unit. A limiting unit is arranged on the base. The limiting unit is used to clamp and limit the two ends of the pipe. After the pipe is placed on the upper part of the support belt, the limiting unit limits the two ends of the pipe. Then, the cutting unit moves to the designated position along the length direction of the base according to the pre-set cutting length and cuts the pipe. In the process of the cutting unit moving along the length direction of the base, the supporting belts connected to the two sides of the cutting unit are driven to rotate under the movement of the cutting unit, so that the supporting belts can rotate in time when the cutting unit moves, and at the same time, the supporting belts can rotate in time when the cutting unit moves. Under the restriction of the unit, the pipe on the support belt will not be displaced along the length direction of the base, and then the tool in the cutting unit starts to cut and cut the pipe. A plurality of support rods are arranged on the support belt, and the support rods are evenly distributed on the support belt along the extension direction of the support belt. The ends of the support rods extending into the guide rails slide and cooperate along the extension direction of the guide rails. When the cutting unit cuts, the support rods can provide sufficient supporting strength for the support belt, ensuring that the cutting unit can smoothly cut the pipe. Moreover, since the total length of the upper end face of the support belt is always fixed when the support belt rotates, the support belt is used to support the pipe. Compared with the traditional base supporting method, the space utilization rate is higher and the base will not be damaged during cutting.

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-Figure 5 , Fig. 9 and Fig.10: A PE-RT floor heating pipe processing and cutting equipment, comprising a horizontally placed base 1 and a cutting unit 2 slidably arranged on the base 1 along the length direction of the base 1; a supporting belt 3 is arranged on the base 1 along the length direction of the base 1, the supporting belt 3 is a long strip structure, and the two ends of the supporting belt 3 are respectively connected to the two sides of the cutting unit 2, and the supporting belt 3 connected to the two sides of the cutting unit 2 is an annular structure arranged on the upper part of the base 1, and the upper part of the annular structure formed by the supporting belt 3 is a horizontal plane structure, and the horizontal plane structure is used to support the coffin, when the cutting unit 2 moves along the length direction of the base 1, the supporting belt 3 rotates under the drive of the cutting unit 2, and a plurality of supporting rods 31 are arranged along the supporting belt 3, the supporting rods 31 are penetrated and arranged in the supporting belt 3 along the width direction of the supporting belt 3, and the two ends of the supporting rods 31 extend from the two sides of the supporting belt 3, and guide rails 32 are arranged on the two sides of the supporting belt 3, and the guide rails 32 are annular structures, and the ends of the supporting rods 31 extending from the supporting belt 3 extend into the guide rails 32 and slide with the guide rails 32.

[0031] In the existing cutting process for PERT floor heating pipes 4, the cutting unit 2 of the floor heating coffin is mostly open, and because the floor heating pipes 4 need to be cut into different lengths according to different usage environments, it is necessary to frequently measure the size of the pipes 4, which will cause the staff to have a large workload when operating, and the traditional manual measurement method has a low accuracy. Therefore, it is necessary to enable the equipment to automatically determine the length of the pipe 4 and cut it. Although the position of the cutting unit 2 of the traditional cutting equipment can be moved along the length direction of the base 1, the lower knife position of the cutting unit 2 cannot be determined during cutting, so that when cutting the pipe 4, the upper end surface of the base 1 will be cut, thereby causing the upper end surface of the base 1 to be cut. The cutting unit 2 in the present invention can avoid the above situation. The specific structure will be described in the subsequent part. The cutting unit 2 in the present invention has a tool 21 and a receiving groove 22. When the tool 21 cuts the pipe 4, the tool 21 will enter the receiving groove 22 after cutting the pipe 4, thereby avoiding the situation that the tool 21 cuts the end surface of the base 1 when cutting. Such a setting will cause the cutting unit 2 to move along the length direction of the base 1. The entire cutting unit 2 needs to move along the base 1, and the upper end surface of the base 1 cannot normally receive the pipe 4. This is because the cutting unit 2 and the base 1 receiving the pipe 4 will be blocked when moving. In order to avoid the above situation, the prior art is used during processing. Only the pipe 4 located on the base 1 can be moved, so there is no need to move the position of the cutting unit 2. However, such operation will cause the operating space of the cutting equipment to occupy a large area. That is, in order to cut the pipe 4, it is necessary to reserve equal length of pipe 4 moving space on both sides of the cutting unit 2, so that the overall length of the base 1 is twice the length of a single pipe 4. In order to avoid the above situation, a support belt 3 is set. The specific working principle is as follows: first, the pipe 4 needs to be placed on the upper part of the support belt 3 along the length direction of the base 1, and the pipe 4 located on the upper part of the support belt 3 passes through the cutting unit 2 horizontally. A limiting unit 5 is set on the base 1. The limiting unit 5 is used to clamp the two ends of the pipe 4 and limit the position. When the pipe 4 is placed on the support belt 3 After the cutting unit 2 is cut, the limiting unit 5 limits the two ends of the pipe 4, and then the cutting unit 2 moves to the specified position along the length direction of the base 1 according to the preset cutting length and cuts the pipe 4. In the process of the cutting unit 2 moving along the length direction of the base 1, the support belt 3 connected to the two sides of the cutting unit 2 is driven to rotate under the movement of the cutting unit 2, so that the support belt 3 can rotate in time when the cutting unit 2 moves. At the same time, under the restriction of the limiting unit 5, the pipe 4 located on the support belt 3 will not be displaced along the length direction of the base 1. Then the tool 21 in the cutting unit 2 starts to cut and cut the pipe 4. A plurality of support rods 31 are arranged on the support belt 3, and the support rods 31 are evenly distributed on the support belt 3 along the extension direction of the support belt 3.The end of the support rod 31 extending into the guide rail 32 slides along the extension direction of the guide rail 32. When the cutting unit 2 cuts, the support rod 31 can provide sufficient support strength for the support belt 3, ensuring that the cutting unit 2 can smoothly cut the pipe 4. Since the total length of the upper end surface of the support belt 3 is always fixed when the support belt 3 rotates, the support belt 3 is used to support the pipe 4. Compared with the traditional base 1 receiving method, the space utilization rate is higher, and the base 1 will not be damaged during cutting.

[0032] Reference Figure 7 and Figure 8 : The cutting unit 2 includes a tool 21 for cutting the pipe 4. The tool 21 moves in the vertical direction. A receiving groove 22 is provided directly below the tool 21. After the tool 21 completes cutting of the pipe 4, it extends into the receiving groove 22. The tool 21 and the receiving groove 22 move synchronously along the length direction of the base 1, and the upper end surface of the receiving groove 22 is coplanar with the upper end surface of the support belt 3.

[0033] The cutting unit 2 also includes a bracket 23 that moves along the length direction of the base 1. The tool 21 is arranged on the bracket 23, and the receiving groove 22 is arranged at the bottom of the bracket 23. Since the tool 21 and the receiving groove 22 can move synchronously along the length direction of the base 1, after the pipe 4 is placed on the support belt 3 and is limited by the limiting unit 5, the cutting unit 2 can move according to the pre-set cutting length, and stop moving when it moves to the specified position. The movement process of the cutting unit 2 is controlled by the bracket 23 along the length direction of the base 1. The cutter 21 and the receiving groove 22 are moved to achieve the above-mentioned effect. Since the cutter 21 and the receiving groove 22 are both arranged on the bracket 23, when the bracket 23 moves, the cutter 21 and the receiving groove 22 can move synchronously. Each time the cutter 21 cuts the pipe 4, the lower part of the cutter 21 must be extended into the receiving groove 22 to complete the cutting. This is because the upper end surface of the receiving groove 22 is coplanar with the upper end surface of the support belt 3. If the cutter 21 does not extend into the receiving groove 22 when cutting the pipe 4, the cutting part of the pipe 4 will not be cut smoothly.

[0034] Reference Figure 8 A slope stopper 221 is provided on the receiving groove 22, at least two slope stoppers 221 are provided, and the two slope stoppers 221 are arranged at both ends of the receiving groove 22 along the width direction of the base 1, and the slopes on the two slope stoppers 221 face each other.

[0035] Although the pipe 4 will pass through the cutting unit 2, that is, pass through the bracket 23 after being placed on the support belt 3, the cutter 21 can still move along the width direction of the base 1 after cutting, so that the pipe 4 on the support belt 3 can be fully cut. That is, if multiple pipes 4 are arranged on the support belt 3 along the width direction of the support belt 3, the cutter 21 only moves along the vertical direction at this time, which cannot meet the needs of cutting all the pipes 4 on the support belt 3. In this case, it is necessary to move the cutter 21 along the width direction of the base 1 to increase the working range of the cutter 21. Although the pipe 4 will pass through the bracket 23, the cross-section of the pipe 4 is mostly a circular structure, which will cause the pipe 4 on the support belt 3 to roll along the width direction of the base 1. In this way, when the cutter 21 cuts the pipe 4, the pipe 4 is affected by the cutter 2 1's cutting force will cause the tube 4 to move in the opposite direction of the cutter 21, that is, the tube 4 will move toward the side of the bracket 23 after being cut by the cutter 21. In this way, when the cutter 21 cuts the above-mentioned tube 4, it will be impossible to completely cut the tube 4. In order to prevent the cutter 21 from cutting the bracket 23 during work, it is necessary to limit the moving stroke of the cutter 21, and this will result in a cutting blind spot. In order to avoid the above situation, a slope stopper 221 is provided on the receiving groove 22, so that the tube 4 located at the upper part of the receiving groove 22 can be prevented from being too close to the bracket 23 when rolling along the width direction of the base 1. Regarding the driver for driving the cutter 21 to move in the vertical direction and along the width direction of the base 1, a two-dimensional slide table can be preferably used. Since the two-dimensional slide table 53 is a prior art, it will not be described here.

[0036] Reference Figure 6 and Figure 7 A pressing unit 24 that moves in a vertical direction is provided on one side of the tool 21, and the pressing unit 24 includes a support plate 242 that is horizontally arranged on one side of the tool 21, and a pressing plate 241 is provided at the lower part of the support plate 242. The upper part of the pressing plate 241 is vertically fixed on an extension rod 243, and the extension rod 243 penetrates the support plate 242 in the vertical direction and slides with the support plate 242. There is a gap between the pressing plate 241 and the support plate 242, and a spring 244 is arranged in the gap along the axis of the extension rod 243, and both ends of the spring 244 are fixedly connected to the pressing plate 241 and the support plate 242 respectively.

[0037] It is worth noting that the horizontal height of the pressing plate 241 located at the bottom of the support plate 242 is lower than the horizontal height of the lower side of the tool 21, that is, when the tool 21 descends in the vertical direction, the pressing plate 241 will contact the pipe 4 before the tool 21 and press the upper part of the pipe 4. The pipe 4 pressed by the pressing plate 241 can no longer move along the width direction of the base 1. When the pressing plate 241 contacts the pipe 4, the tool 21 and the support plate 242 continue to descend in the vertical direction. At this time, the gap between the support plate 242 and the pressing plate 241 is reduced, and the spring 244 located in the gap is gradually squeezed. The elastic force of the spring 244 gradually increases the thrust of the pressing plate 241, so that the pressing plate 241 can further press and fix the pipe 4 before the tool 21 contacts the pipe 4, thereby ensuring the stability of the pipe 4 when the tool 21 cuts the pipe 4.

[0038] Reference Figure 2 and Figure 5 : A limiting unit 5 is set on the base 1, and the limiting unit 5 includes a fixed plate 51 fixedly set on one end of the base 1, and a movable plate 52 that moves along the length direction of the base 1 is set at the other end of the base 1. When the movable plate 52 is located on the end of the base 1 where the fixed plate 51 is not set, the distance between the fixed plate 51 and the movable plate 52 is at the maximum distance.

[0039] The maximum spacing is intended to illustrate the maximum length of the pipe 4 that can be processed by the cutting device. If the length of the pipe 4 is greater than the maximum spacing, the pipe 4 cannot be placed between the fixed plate 51 and the movable plate 52, so the cutting unit 2 cannot cut the pipe 4. A slide 53 is provided on one side of the movable plate 52 along the length direction of the base 1. The slide 53 is used to drive the movable plate 52 to move along the length direction of the base 1. A rangefinder is provided on the movable plate 52, and the rangefinder points horizontally to the fixed plate 51. When the movable plate 52 and the fixed plate 51 respectively clamp the two ends of the pipe 4, the rangefinder can monitor the actual length of the pipe 4, so that the cutting unit 2 can move according to the preset cutting length.

[0040] Reference Figure 3-Figure 5 : A dust removal unit 6 is arranged between the cutting unit 2 and the fixed plate 51, and the dust removal unit 6 includes a corrugated sleeve 61. The corrugated sleeve 61 is arranged between the fixed plate 51 and the cutting unit 2 along the length direction of the base 1, and the two ends of the corrugated sleeve 61 are respectively fixedly connected to the fixed plate 51 and the cutting unit 2. The fan 62 is rotatably arranged on the fixed plate 51, and the collecting unit 63 is arranged on the side of the fixed plate 51 away from the cutting unit 2. A suction chamber is formed in the corrugated sleeve 61, and the fan 62 rotates to draw the air in the suction chamber into the collecting unit 63.

[0041] When the cutting unit 2 cuts the pipe 4, a lot of debris will inevitably be generated at the cutting point between the pipe 4 and the cutter 21. The raw material of the PERT pipe 4 is polyethylene, which is light in weight. The generated cutting debris is not easy to be cleaned. Therefore, a dust removal unit 6 is set on one side of the cutting unit 2. The dust removal unit 6 is used to remove dust from the cutting point between the cutting unit 2 and the pipe 4. When the cutting unit 2 cuts the pipe 4, the fan 62 is started, and the fan 62 draws the air in the suction chamber into the collecting unit 63, thereby preventing the pipe 4 debris from floating to the outside.

[0042] Reference Figure 3 and Figure 4 The collecting unit 63 includes a collecting box 632 arranged on one side of the fan 62, a collecting pipe 631 is arranged on one side of the fan 62, the collecting pipe 631 is communicated with the suction chamber, one end of the collecting pipe 631 away from the fan 62 extends into the collecting box 632, a sponge 633 is horizontally arranged in the collecting box 632, the sponge 633 divides the collecting box 632 into an upper cavity and a lower cavity in a vertical direction, the collecting pipe 631 penetrates the sponge 633 and extends into the lower cavity, the lower cavity is filled with water, and the water level is coplanar with the upper end face of the sponge 633.

[0043] After the fan 62 rotates, the air in the suction chamber is sucked into the collecting pipe 631. A diverter 634 is provided on the end of the collecting pipe 631 located in the lower cavity. The diverter 634 is used to disperse the air in the collecting pipe 631 and inject it into various positions of the collecting box 632. An exhaust port is provided on the upper portion of the collecting box 632. The air in the suction chamber enters the lower cavity through the collecting pipe 631. The air is mixed with polyethylene debris. The air can be discharged through the gaps in the sponge 633, while the polyethylene debris mixed in the air cannot be discharged through the sponge 633, but is intercepted by the sponge 633. Since the polyethylene debris is easily generated due to friction during the transportation process, filling the lower cavity with water can eliminate static electricity, thereby preventing the polyethylene debris from adhering to the lower cavity, which is inconvenient for subsequent cleaning work.

[0044] Reference Figure 8 A fan 222 is provided at the bottom of the receiving groove 22. The fan 222 can blow air from bottom to top in a vertical direction. The fan 222 is used to blow out the debris that falls into the receiving groove 22.

[0045] When the fan 62 draws out the air in the suction chamber, the receiving groove 22 is an airflow blind area, that is, the debris falling into the receiving groove 22 is not easily drawn out by the fan 62. Therefore, a fan 222 is arranged at the bottom of the receiving groove 22, so that the fan 222 blows the air from bottom to top in the vertical direction, thereby avoiding the situation where too much debris accumulates in the receiving groove 22.

[0046] Reference Figure 8-Figure 10: The cutting unit 2 also includes a bracket 23, the tool 21 and the receiving groove 22 are both arranged on the bracket 23, the driving unit 25 is used to drive the bracket 23 to move along the length direction of the base 1, and the driving unit 25 includes a threaded rod 251, the threaded rod 251 passes through the bracket 23 along the length direction of the base 1 and is threadedly matched with the bracket 23.

[0047] The driving unit 25 also includes a guide rod 252 and a rotation driver 253.
