Description

Technical Field

[0001] This utility model relates to the field of sealing strip manufacturing technology, and in particular to welding equipment for door and window sealing strips. Background Technology

[0002] At door and window locations, sealing strips need to be installed to improve the sealing performance when the doors and windows are closed, in order to achieve purposes such as waterproofing, dustproofing, heat insulation, and noise reduction. When forming a ring-shaped sealing structure such as a square frame, welding equipment is required to weld two or more sealing strips sequentially towards each other.

[0003] Existing welding equipment includes, for example, a window and door sealing strip welding machine disclosed in patent document CN104924597B (authorization announcement number) and a welding machine for butt welding of sealing strips disclosed in patent application publication number CN106985397A (application publication number). These machines include a worktable, drive mechanism, heating mechanism, PE film pulling device, and scissors, and can automatically complete the butt welding of two sealing strips. The two sealing strips are placed on mounting seats (or clamping mechanisms) on the left and right sides respectively, with a heatable PE film placed in the middle. The two mounting seats are brought close together to clamp the PE film, thus achieving the butt welding of the two sealing strips. With appropriate adjustments, our company currently uses two horizontally placed upper and lower molds (equivalent to the mounting seats or clamping mechanisms in the prior art) to fix the sealing strips, and then the two sealing strips are welded together.

[0004] During use, the following problems exist: Although the welding process is automated, placing the seal into the shaping groove on the lower mold is still done manually. The seal is held by one end and gradually moved along the direction of the shaping groove to be inserted into it. Because the seal is relatively soft and has a certain length, after the end of the seal enters the shaping groove, the part that has not entered is unsupported and droops and bends near the shaping groove. At this time, the seal is not easy to enter the shaping groove, resulting in a long insertion time and lack of stability. At the same time, if the seal is continued to be inserted with force while it is bent, there is a probability of damaging the seal.

[0005] Therefore, the problem that the seal is prone to bending when entering the shaping groove, making it difficult to quickly insert into the shaping groove, needs to be solved. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a door and window sealing strip welding equipment to address the above-mentioned technical deficiencies. This equipment solves the problem that the sealing element is easily bent when entering the shaping groove, which makes it impossible to quickly insert it into the shaping groove.

[0007] The technical solution adopted by this utility model is: to provide a door and window sealing strip welding equipment, in which two lower molds slide relative to each other in the left-right direction on a worktable, and the lower molds have at least one shaping groove, and the sealing element is inserted and disposed in the shaping groove; including:

[0008] A mounting bracket is provided at the front end of the workbench;

[0009] The bracket has two brackets, which are respectively disposed on the left and right sides of the mounting frame;

[0010] A plurality of guide rods are provided, each of the brackets is provided with a guide rod, the guide rods point to the shaping groove, and the guide rods located on the left and right sides of the mounting bracket are symmetrically arranged;

[0011] The positioning seat has several units, which are rotatably mounted on the guide rod. The positioning seat has a counterweight on its lower side, which is located below the guide rod. The positioning seat has a positioning groove at its upper end, which is used to accommodate the sealing element.

[0012] To further optimize this technical solution, the positioning seat is slidably and rotatably mounted on the guide rod, and after the positioning seat slides, it moves closer to or further away from the lower mold.

[0013] To further optimize this technical solution, the lower mold has two parallel shaping grooves; each bracket is provided with two guide rods, which are arranged in parallel and point to the two shaping grooves respectively.

[0014] To further optimize this technical solution, the guide rod has a slip ring at its end near the bracket, and the slip ring is slidably mounted on the bracket.

[0015] Further optimization of this technical solution also includes:

[0016] The spade plate is used to slide against the upper end of the lower mold.

[0017] To further optimize this technical solution, the front end of the shovel plate has a control lever; it also includes:

[0018] An elastic pull rope is fixed at both ends to the left and right sides of the mounting frame, and the middle part of the elastic pull rope is connected to the control rod to provide force for the shovel plate to move away from the lower mold.

[0019] To further optimize this technical solution, both the left and right sides of the shovel plate have inclined outer expansion plates. When the two lower molds approach each other, the two lower molds are located between the two outer expansion plates.

[0020] Further optimization of this technical solution also includes:

[0021] A plurality of hooks are provided, which are located at the front end of the mounting bracket and are used to attach seals.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. The guide rod and positioning seat can support the seal located outside the forming groove, preventing the seal from sagging and bending, so that the seal can enter the forming groove of the lower mold more smoothly.

[0024] 2. The positioning groove at the upper end of the positioning seat accommodates the sealing element. Before the sealing element is inserted and welded, part of the sealing element is inserted into the shaping groove and part is located in the positioning groove. By rotating the positioning seat, when the two lower molds move closer to each other, the positioning seat can adapt to the rotation, causing the sealing element to leave the positioning groove. Then, by the weight of the counterweight, the positioning seat returns to its original position. During the welding of the two sealing elements, a new sealing element to be welded can be placed on the positioning seat for use, which helps to save time. Attached Figure Description

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] like Figure 1-8 As shown, the door and window sealing strip welding equipment includes two lower molds 2 that slide relative to each other in the left-right direction on a workbench 1. Each lower mold 2 has at least one shaping groove 201, and the sealing element 3 is inserted into the shaping groove 201. The equipment includes: a mounting frame 4, located at the front end of the workbench 1; two supports 5, which are respectively located on the left and right sides of the mounting frame 4; several guide rods 7, each of which is provided on the support 5 and points to the shaping groove 201. The guide rods 7 on the left and right sides of the mounting frame 4 are symmetrically arranged; and several positioning seats 6, which are rotatably mounted on the guide rods 7. Each positioning seat 6 has a counterweight 601 on its lower side, which is located below the guide rods 7. The upper end of the positioning seat 6 has a positioning groove 602 for accommodating the sealing element 3.

[0040] When in use, the welding process is divided into three stages: material placement, material welding, and material removal, and then the operation is repeated.

[0041] During the material placement stage, the two lower molds 2 are separated with a large gap between them. At this time, the positioning seat 6 is used to insert the sealing element 3 into each of the two lower molds 2. The sealing element 3 is placed in the positioning groove 602, which supports the sealing element 3. The positioning groove 602 on one side of the cylinder is opposite to the shaping groove 201. The sealing element 3 can be pushed into the shaping groove 201 by hand. The operation of the sealing elements 3 on the left and right sides is the same.

[0042] During the material welding stage, part of the sealing element 3 is located in the shaping groove 201, and part is located in the positioning groove 602. After the PE film heating operation is completed, the two lower molds 2 (the lower mold 2 is used as an example for explanation; at this time, the upper mold should move down to abut against the lower mold 2, clamping the sealing element 3 in the middle, and then move synchronously) move closer to the middle, and the ends of the two sealing elements 3 clamp the PE film for welding. During the movement of the lower mold 2 closer, the sealing element 3 disengages from the positioning groove 602, and the positioning seat 6 adaptively rotates and moves at an angle, causing the positioning groove 602 to tilt. The sealing element 3 can then be easily disengaged from the positioning groove 602. Under the gravity of the counterweight 601, the positioning seat 6 automatically rotates and resets. Then, a new sealing element 3 to be welded can be placed in the positioning groove 602.

[0043] After welding is completed, unload the material, the upper mold rises and separates, and the welded seal 3 can be removed. Then the two lower molds 2 move away from each other.

[0044] Furthermore, the positioning seat 6 is slidably and rotatably mounted on the guide rod 7. After the positioning seat 6 slides, it moves closer to or further away from the lower mold 2.

[0045] During use, the positioning seat 6 can rotate to automatically disengage from and reset the seal 3. The positioning seat 6 can slide to facilitate adjustment of the distance between the positioning seat 6 and the lower mold 2, so as to better align the end of the seal 3 with the end of the shaping groove 201, and to accommodate different people's hand-held operating habits, making adjustment more convenient.

[0046] Furthermore, the lower mold 2 has two parallel shaping grooves 201; each bracket 5 is provided with two guide rods 7, which are arranged in parallel and point to the two shaping grooves 201 respectively.

[0047] When the current mold 2 uses two shaping grooves 201, the guide rod 7 and the positioning seat 6 are matched and set accordingly, which can simultaneously weld two sets of seals 3, thus improving efficiency.

[0048] Furthermore, the guide rod 7 has a slip ring 701 at its end near the bracket 5, and the slip ring 701 is slidably mounted on the bracket 5.

[0049] In use, the guide rod 7 slides through the slip ring 701, which can adjust the position of the guide rod 7, thereby adjusting the relative position of the positioning seat 6 and the lower mold 2. After adjustment, the positioning seat 6 can be aligned with the shaping groove 201 to accommodate different lower molds 2 (the position, spacing, etc. of the shaping groove 201 on different lower molds 2 may be different).

[0050] Furthermore, it also includes: a spade plate 8, which is used to slide against the upper end of the lower mold 2.

[0051] In use, the shovel plate 8 facilitates faster material unloading. The existing unloading method is manual pulling, but the shaping groove 201 is compatible with the seal 3, and the seal 3 is partially located within the shaping groove 201, making it difficult to quickly and reliably remove the welded seal 3. The shovel plate 8 can slide on the upper end of the lower mold 2, entering from the front and lifting the seal 3 from below to disengage it from the shaping groove 201. Then, it slides backward on the upper end of the lower mold 2, gradually shoveling the seal 3 out of the shaping groove 201. The shovel plate 8 allows both welded, vertically aligned seals 3 to be simultaneously subjected to the shoveling force, making it easier to remove the seal 3 and reducing damage to it.

[0052] The vertical cross-section of the shovel plate 8 can be triangular, and the tip can be chamfered. The chamfered tip is then shoveled out by the seal 3.

[0053] Furthermore, the front end of the shovel plate 8 has a control rod 801; it also includes an elastic pull rope 9, with both ends fixed to the left and right sides of the mounting frame 4 respectively, and the middle part of the elastic pull rope 9 is connected to the control rod 801 to provide force for the shovel plate 8 to move away from the lower mold 2.

[0054] During use, the elastic pull rope 9 can automatically pull back the shovel plate 8 to prevent the operator from forgetting to retract the shovel plate 8 after it has removed the seal 3, which could cause damage to the equipment due to squeezing. The control lever 801 is easy for the operator to hold. When the shovel plate 8 moves backward to remove the seal 3, the elastic pull rope 9 extends and stores energy. After removing the seal 3, the operator can hold the control lever 801 to retract the shovel plate 8 or the elastic pull rope 9 can return to its original position and apply tension to pull the shovel plate 8 back, preventing the shovel plate 8 from remaining on the lower mold 2.

[0055] Furthermore, both the left and right sides of the shovel plate 8 have inclined outer extension plates 802. When the two lower molds 2 approach each other, the two lower molds 2 are located between the two outer extension plates 802.

[0056] In use, the outward expansion plates 802 on both sides of the shovel plate 8 can expand the contact range of the shovel plate 8, and better lift and shovel out the seal 3. For example, the seal 3 may protrude from the left or right side of the lower mold 2. At this time, the outward expansion plates 802 can lift the seal 3 on the left or right side. The shovel plate 8 is located in front of the lower mold 2, and the middle of the shovel plate 8 can lift and shovel out the seal 3 on the front side and the seal 3 on the upper side of the lower mold 2.

[0057] Furthermore, it also includes: hooks 401, having several of them, hooks 401 being disposed at the front end of the mounting bracket 4 for attaching the sealing element 3.

[0058] When in use, the mounting bracket 4 is located in front of the workbench 1. The hook 401 can hang the two vertically welded seals 3 or place the seals 3 flat for temporary storage.
