Description

Technical Field

[0001] This invention relates to a manufacturing process for a self-adhesive waterstop, specifically to a process device and method for adjusting the driving traction of waterstops of different thicknesses. Background Technology

[0002] Self-adhesive plastic waterstops have applications in various technical fields, such as building structures, water conservancy projects, and civil defense facilities. During construction in these fields, construction joints are often left. To prevent leakage or seepage in these joints, special treatment is usually required. A common and effective method is to use steel-edged rubber waterstops to waterproof these joints.

[0003] In the initial stage of producing this type of steel plate waterstop, a rubber waterstop needs to be processed first. Rubber waterstops are generally made from certain chemical raw materials, which are heated and melted, then extruded to form a continuously conveyed strip of rubber. After cooling, coating with water, and curling, the final product is formed. However, the traction process of this type of rubber strip waterstop in existing technologies is not stable, especially when its thickness is slightly adjusted or changed. How to quickly change the traction structure to ensure the stable and uniform forward movement of the rubber strip waterstop is a technical challenge. Furthermore, existing technologies often require machine shutdowns and parameter adjustments or structural replacements of the traction structure, reducing work efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a device structure for improving a traction device to achieve targeted pressure adjustment.

[0005] To achieve the above objectives, the present invention provides a manufacturing process for a self-adhesive plastic waterstop, comprising a material storage bin, a material mixing device, a feeding container, a heated extruder, a cooling device, a traction device, a conveying device, a gluing device, and a winding device connected in sequence; the plurality of material storage bins are used to store raw materials; the material mixing device is used to extract the raw materials from the material storage bins, mix them, and discharge them into the feeding container located at the bottom; the material is added to the heated extruder in the feeding container and extruded under set temperature and pressure settings to form a continuous strip-shaped waterstop; the strip-shaped waterstop passes through the cooling device and is cooled by contact cooling with circulating water; the traction device is used to move the strip-shaped waterstop; and the strip-shaped waterstop is coated with glue on one side after passing through the gluing device, and then wound into a roll at the winding device;

[0006] The traction device includes a rotating rod with multiple axially extending traction plates. The traction plates are connected to a linkage rod, which is movably disposed within the rotating rod. A movable rod is disposed inside the rotating rod, and the movable rod has a driving protrusion that abuts against the linkage rod.

[0007] The beneficial effects of the above solution are as follows: By improving the traction device, when it is necessary to adjust the traction pressure, the moving rod is moved accordingly. When the moving rod moves axially, it drives the protrusion to complete the driving movement of the linkage rod, thereby realizing the driving movement of the traction plate. This causes the traction plate to move outward or inward, thus realizing the contact pressure with the waterstop. Therefore, it can be adjusted according to the thickness of the waterstop or according to the actual production situation.

[0008] In a preferred embodiment, the material storage tank includes a main material tank and a secondary material tank. The main material tank and the secondary material tank are connected to the mixing tank of the material mixing device above via feeding pipes. The lower outlet of the mixing tank is connected to a first receiving tank and a second receiving tank respectively via a three-way valve. Both the first receiving tank and the second receiving tank are connected to the feeding container via a delivery pipe. The feeding container is connected to the feeding cylinder via a feeding pipe. The feeding cylinder is located upstream of the heated extruder. The feeding cylinder has a quantitative control valve and a discharge channel. The discharge channel adds material into the heated extruder. The heated extruder has a main tube, and an electric heating radiation device is wound around the outer wall of the main tube. The heated extruder also includes a control console, which has control switches for multiple heating modes and multiple extrusion modes.

[0009] In a preferred embodiment, the cooling device includes a gantry frame, a receiving trough, a main conveying roller, and a conveying roller assembly. The gantry frame is located at the head of the receiving trough, and a set of cooling water pipes are provided at the lower end of the transverse plate of the gantry frame. The main conveying roller is located at the middle of the receiving trough, and the conveying roller assembly is located at the tail of the receiving trough.

[0010] Additionally, a counting wheel is provided on the downstream side of the receiving tank, the counting wheel being connected to a controller, and the counting wheel and the controller being used to measure the length of the passing waterstop.

[0011] In a preferred embodiment, the traction device further includes an external drive motor, an internal drive motor, a fixed shaft, a drive gear, a driven gear, and an elastic connecting plate. The fixed shaft has external threads, and the inner wall thread of the moving rod is threaded onto the external threads on the fixed shaft. The moving rod can move and rotate relative to the fixed shaft. The driving protrusion on the moving rod includes a first conical protrusion and a second conical protrusion. The first conical protrusion is used to cooperate with a linkage rod on a first side, and the second conical protrusion is used to cooperate with a linkage rod on a second side. The elastic connecting plate includes a transverse plate portion, a first side raised portion, and a second side raised portion. The outer ends of the first side raised portion and the second side raised portion are connected to the traction plate. The driven gear is connected to the outer end of the moving rod. The driven gear meshes with the drive gear, and the drive gear is connected to the internal drive motor.

[0012] The self-adhesive plastic waterstop manufacturing process provided by this invention includes the following steps:

[0013] The raw materials are stored in the material storage box. The material mixing device extracts the raw materials from the material storage box, mixes them, and discharges them into the feeding container located at the bottom. The material is added into the heating extruder and extruded under the set temperature and pressure settings to form a continuous strip-shaped waterstop. The strip-shaped waterstop is cooled by contact cooling with circulating water through a cooling device. The traction device drives the strip-shaped waterstop to move. After passing through the gluing device, the strip-shaped waterstop is coated with glue on one side and then rolled into a roll at the position of the winding device.

[0014] When it is necessary to apply contact pressure between the traction plate and the strip waterstop, the moving rod is activated to move along the axial direction of the rotating rod, thereby causing the driving protrusions at different positions to contact the linkage rod, adjusting the position of the linkage rod, and thus causing the linkage rod to drive the traction plate to move toward or away from the strip waterstop.

[0015] The manufacturing process of self-adhesive plastic waterstop provided by this invention includes the following steps: the main material box and the auxiliary material box feed the material into the mixing tank through the feeding pipe. After stirring and mixing in the mixing tank, a uniformly mixed material is formed. The mixed material is selectively stored in the first receiving box or the second receiving box under the control of the three-way valve. Then, the material enters the feeding container under negative pressure through the delivery pipe, and then enters the feeding cylinder. Subsequently, it enters the heated extruder. The amount of material added is quantitatively controlled by the quantitative control valve. Different modes are used to pass the material through the main tube by selecting the extrusion mode control switch on the control panel. The material is heated and melted by the electric heating radiation device, and finally, a strip-shaped waterstop is extruded from the end position.

[0016] The manufacturing process of the self-adhesive plastic waterstop provided by the present invention includes the following steps: when the extruded strip waterstop passes through the gantry, the cooling water pipe continuously flows cooling water to cool the strip waterstop passing below, and the counting wheel transmits a signal to the controller through the rotation process, and the controller calculates the length.

[0017] The manufacturing process of self-adhesive plastic waterstop provided by this invention includes the following steps:

[0018] The internal drive motor provides power, causing the drive gear to rotate. The drive gear then drives the driven gear and the moving rod to rotate. During rotation, the moving rod moves along the fixed shaft, causing the drive protrusions at different positions to contact and engage with the linkage rod. Due to the different heights of the drive protrusions, the positions of the linkage rod and the traction plate change, thereby adjusting the contact pressure between the traction plate and the waterstop. Furthermore, through the positional relationship between the first and second vertebral protrusions, the two ends of the traction plate have different pressures.

[0019] When the moving rod moves axially along the fixed shaft, the moving rod simultaneously achieves circumferential rotation. This circumferential rotation, combined with the elastic action of the elastic connecting plate, causes the traction plate to vibrate, thereby removing the adhesion between the moving rod and the waterstop.

[0020] The drive gear has a certain width in the axial direction, and the driven gear reciprocates along the width direction of the drive gear. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] First embodiment:

[0034] like Figures 1 to 10The present invention provides a manufacturing process for a self-adhesive plastic waterstop, comprising a material storage bin 1, a material mixing device 2, a feeding container 3, a heated extruder 4, a cooling device 5, a traction device 6, a conveying device 7, a gluing device 8, and a winding device 9 connected in sequence. The multiple material storage bins 1 are used to store raw materials. The material mixing device 2 is used to extract the raw materials from the material storage bins 1, mix them, and discharge them into the feeding container 3 located at the bottom. The material is added to the heated extruder 4 from the feeding container 3 and extruded under set temperature and pressure conditions to form a continuous strip-shaped waterstop 10. The strip-shaped waterstop 10 is cooled by contact cooling with circulating water through the cooling device 5. The traction device 6 is used to move the strip-shaped waterstop 10. After passing through the gluing device 8, the strip-shaped waterstop 10 is coated with glue on one side and then wound into a roll at the winding device 9.

[0035] The traction device 6 includes a rotating rod 61 with multiple axially extending traction plates 62. The traction plates 62 are connected to a linkage rod 63, which is movably disposed within the rotating rod 61. A movable rod 60 is disposed inside the rotating rod 61, and the movable rod 60 has a driving protrusion 64 that abuts against the linkage rod 63.

[0036] The material storage tank 1 includes a main material tank 11 and a secondary material tank 12. The main material tank 11 and the secondary material tank 12 are connected to the mixing tank 21 of the material mixing device 20 above via a feeding pipe 13. The material can be fed into the mixing tank 21 by vacuum. The lower outlet of the mixing tank 21 is connected to the first receiving tank 22 and the second receiving tank 23 respectively via a three-way valve. The first receiving tank 22 and the second receiving tank 23 are both connected to the feeding container 3 via a delivery pipe 24. The feeding container 3 is fed by the upper... The feed pipe 31 is connected to the feed cylinder 32, which is located on the upstream side of the heated extruder 4. The feed cylinder 32 has a quantitative control valve and a discharge channel 33. The discharge channel 33 adds material into the heated extruder 4. The heated extruder 4 has a main tube 41, and an electric heating radiation device 42 is wound around the outer wall of the main tube 41. The heated extruder 4 also includes a control console 43, which has control switches 45 for multiple heating modes and multiple extrusion modes. The main material box 11 and the auxiliary material box 12 feed the material into the mixing tank 21 through the feeding pipe 13. After being stirred and mixed in the mixing tank 21, a uniformly mixed material is formed. The mixed material is selectively stored in the first receiving box 22 or the second receiving box 23 under the control of the three-way valve. Then, the material enters the feeding container 3 under negative pressure under the action of the delivery pipe 24, and then enters the feeding cylinder 32. Subsequently, it enters the heated extruder 4. The amount of material added is quantitatively controlled by the quantitative control valve. Different modes are used to pass the material through the main tube 41 by selecting the extrusion mode control switch 45 on the control console 43. The material is heated and melted by the electric heating radiation device 42, and finally the strip-shaped waterstop 10 is extruded from the end position.

[0037] The cooling device 5 includes a gantry frame 51, a receiving trough 52, a main conveying roller 53, and a conveying roller group 54. The gantry frame 51 is located at the head of the receiving trough 52. A set of cooling water pipes 56 are located at the lower end of the transverse plate 55 of the gantry frame 51. The main conveying roller 53 is located in the middle of the receiving trough 52, and the conveying roller group 54 is located at the tail of the receiving trough 52. Additionally, a counting wheel 57 is located downstream of the receiving trough 52. The counting wheel 57 is connected to a controller, and the counting wheel 57 and the controller are used to measure the length of the passing strip-shaped waterstop 10. When the extruded strip-shaped waterstop 10 passes through the gantry frame 51, the continuously flowing cooling water from the cooling water pipes 56 cools the strip-shaped waterstop 10 below. The counting wheel 57 transmits a signal to the controller during its rotation, and the controller calculates the length.

[0038] The self-adhesive plastic waterstop manufacturing process provided by this invention includes the following steps:

[0039] The raw materials are stored in the material storage box 1. The material mixing device 2 extracts the raw materials from the material storage box 1, mixes them, and discharges them into the feeding container 3 located at the bottom. The material is added into the heating extruder 4 from the feeding container 3 and extruded under the set temperature and pressure settings to form a continuous strip-shaped waterstop 10. The strip-shaped waterstop 10 passes through the cooling device 5 and is cooled by contact with circulating water. The traction device 6 drives the strip-shaped waterstop 10 to move. After passing through the gluing device 8, the strip-shaped waterstop 10 is coated with glue on one side and then rolled into a roll at the position of the winding device 9.

[0040] When it is necessary to adjust the contact pressure between the traction plate 62 and the strip-shaped waterstop 10, the moving rod 60 is activated to move along the axial direction of the rotating rod 61, thereby causing the driving protrusion 64 at different positions to contact the linkage rod 63. Adjusting the position of the linkage rod 63 causes it to move the traction plate 62 toward or away from the strip-shaped waterstop 10. Specifically, a trough structure is located below the traction device. When the waterstop passes through the trough structure, the bottom of the waterstop contacts the bottom plate of the trough structure. Then, during rotation, the traction plate 62 moves the waterstop through pressure contact, thus achieving traction.

[0041] Second embodiment:

[0042] The traction device 6 further includes an external drive motor 640, an internal drive motor 65, a fixed shaft 66, a drive gear 67, a driven gear 68, and an elastic connecting plate 69. The fixed shaft 66 has an external thread 660, and the inner wall thread 600 of the moving rod 60 is sleeved on the external thread 660 of the fixed shaft 66. The moving rod 60 can move and rotate relative to the fixed shaft 66. The driving protrusion 64 on the moving rod 60 includes a first conical protrusion 641 and a second conical protrusion 642. The first vertebral protrusion 641 is used to cooperate with 631, and the second vertebral protrusion 642 is used to cooperate with 632. The elastic connecting plate 69 includes a transverse plate portion 691, a first side protrusion 692, and a second side protrusion 693. The outer ends of the first side protrusion 692 and the second side protrusion 693 are connected to the traction plate 62. The driven gear 68 is connected to the outer end of the moving rod 60. The driven gear 68 is meshed with the driving gear 67, and the driving gear 67 is connected to the internal drive motor 65.

[0043] The manufacturing process of self-adhesive plastic waterstop provided by this invention includes the following steps:

[0044] The internal drive motor 65 provides power, causing the drive gear 67 to rotate. The drive gear 67 then drives the driven gear 68 and the moving rod 60 to rotate. During rotation, the moving rod 60 moves along the fixed shaft 66, causing the driving protrusion 64 at different positions to contact and engage with the linkage rod 63. Due to the different heights of the driving protrusions 64, the positions of the linkage rod 63 and the traction plate 62 change, thereby adjusting the contact pressure between the traction plate 62 and the waterstop 10. Furthermore, through the positional relationship between the first vertebral protrusion 641 and the second vertebral protrusion 642, the two ends of the traction plate 62 have different pressures.

[0045] When the moving rod 60 moves axially along the fixed shaft 66, the moving rod 60 simultaneously achieves circumferential rotation and, in conjunction with the elastic action of the elastic connecting plate 69, causes the traction plate 62 to vibrate to a certain extent, thereby removing the adhesion between the moving rod 60 and the waterstop 10.

[0046] The drive gear 67 has a certain width in the axial direction, and the driven gear 68 reciprocates along the width direction of the drive gear 67.

[0047] The specific structures of the heated extruder 4, the glue coating device 8, and the coiling device 9 all adopt existing technologies. The raw materials used for the waterstop are also existing technologies, and will not be described in detail here.

[0048] When the waterstop moves unevenly or asymmetrically at both ends during the traction process, the contact pressure between the two ends and the waterstop is adjusted by the independent pressure adjustment of the traction plates on both sides, thereby correcting the positional deviation of the waterstop.

[0049] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
