Description

Technical Field

[0001] The utility model relates to the technical field of thermal break aluminum production, in particular to a thermal break aluminum production line. Background Art

[0002] The thermal break aluminum includes two aluminum profiles and a heat insulation strip connected between the two aluminum profiles. The production process of the aluminum thermal break is generally to first insert the upper and lower sides of the heat insulation strip into the notches of the two aluminum profiles, and then roll the vertical heads of the notches to obtain the finished product. For example, the Chinese invention patent 2013100676217 discloses an automatic strip threading process for heat-insulating thermally-broken aluminum alloy door and window profiles. This process is a commonly used process for producing thermally-broken aluminum in the prior art. The process steps are summarized as follows: the lower profile and the upper profile are respectively toothed, and the toothing method is upper toothing, that is, the notches are facing upward when the teeth are opened; then the upper profile is lifted, transferred and turned 180°, so that the notch of the upper profile is facing downward and is arranged opposite to the notch of the lower profile one above and one below; then the strip threading machine is used to thread the insulation strip into the notch of the upper profile and the notch of the lower profile at the same time to obtain a semi-finished product; finally, the semi-finished product is sent to a rolling machine, and the rolling machine rolls the vertical head of the notch, and the upper and lower sides of the insulation strip are respectively fixed to the upper profile and the lower profile to obtain a finished product.

[0003] The above-mentioned prior art has the following problems: before threading the strip, the upper profile needs to be lifted, transferred and flipped 180°. If manual operation is adopted, the manpower consumption is large. If automated equipment is adopted, the structural complexity of the equipment is greatly increased, which greatly increases the manufacturing cost of the equipment. In addition, after the upper profile is transferred to the top of the lower profile, if the upper profile is offset at an angle relative to the lower profile, the profile will be subjected to a rapid correction force when threading the plastic strip. This force will cause the profile to jump on the machine, generating a loud noise, and the jumping profile also poses a certain safety risk. The above-mentioned problems need to be solved urgently.

[0044] The following is a detailed description of the embodiments of the present utility model.

[0045] In this embodiment, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in this embodiment can be understood according to the specific circumstances. The directional words that appear in this embodiment are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of this embodiment changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0046] The utility model also provides a thermally-broken aluminum production line, such as Figures 1 to 21 As shown, it includes a feeding device 1, a toothed strip device 2, a longitudinal translation device 3, a rolling device 4 and a material receiving device 6 which are arranged in sequence along the transverse direction, and also includes a heat insulation strip storage table 5.

[0047] The feeding device 1 includes a first feeding table 11 and a second feeding table 12 arranged in the longitudinal direction, and the toothed strip device 2 includes a first toothed strip machine 21 and a second toothed strip machine 22 arranged in the longitudinal direction. In the transverse direction, the first feeding table 11 is opposite to the first toothed strip machine 21 so that the first feeding table 11 can feed the lower profile 01 into the first toothed strip machine 21. The first toothed strip machine 21 is used to clamp the insulation strip 03. The first toothed strip machine 21 is also used to The notch 04 of the upper profile 01 is toothed and then the lower profile 01 is inserted into the lower edge 031 of the thermal insulation strip 03. The second feeding table 12 is opposite to the second toothed strip machine 22 so that the second feeding table 12 can feed the upper profile 02 into the second toothed strip machine 22. The second toothed strip machine 22 is used to clamp the thermal insulation strip 03. The second toothed strip machine 22 is also used to tooth the notch 04 of the upper profile 02 and then insert the upper profile 02 into the upper edge 032 of the thermal insulation strip 03. Usually, the first feeding table 11 and the second feeding table 12 are conveyor roller feeding tables, and multiple rollers are arranged in the longitudinal direction. The first toothed strip-sleeving machine 21 and the second toothed strip-sleeving machine 22 are both provided with a toothed mechanism and a clamp 23. The toothed mechanism is provided with a toothed knife 05. The structure and working principle of the toothed mechanism are prior art, and therefore are not described in detail in this application. The clamp 23 is used to clamp the thermal insulation strip 03. The clamp 23 may adopt the common clamps in the prior art, or may adopt the new clamp 23 provided in this embodiment. The structure of the new clamp 23 is described below.

[0048] The longitudinal translation device 3 is used to receive the first-order semi-finished product and translate the first-order semi-finished product from the position opposite to the first toothed striping machine 21 to the position opposite to the second toothed striping machine 22. The longitudinal translation device 3 is also used to translate the second-order semi-finished product from the position opposite to the second toothed striping machine 22 to the position opposite to the rolling device 4. The longitudinal translation device 3 includes a plurality of conveyor belts extending in the transverse direction, by means of which the first-order semi-finished product and the second-order semi-finished product are translated; at the same time, the longitudinal translation device 3 also includes a first lifting conveyor roller for reducing friction when receiving the first-order semi-finished product, a lifting platform for supporting the first-order semi-finished product when the first-order semi-finished product is striped on the upper profile 02, and a second lifting conveyor roller for reducing friction when the second-order semi-finished product is sent away. The first lifting and conveying roller includes a plurality of conveying rollers that can be lifted and lowered relative to the longitudinal translation device 3 and arranged in the longitudinal direction. When the lower profile 01 passes through the first toothed sleeve machine 21 and arrives at the longitudinal translation device 3, the first lifting and conveying roller rises and receives the lower profile 01 to reduce the friction between the lower profile 01 and the longitudinal translation device 3. When the first-order semi-finished product is to be sent to the next position by the conveyor belt, the first lifting and conveying roller descends. The lifting platform can be lifted and lowered relative to the longitudinal translation device 3. When the first-order semi-finished product arrives at the position opposite to the second toothed sleeve machine 22, the lifting platform rises. When the second-order semi-finished product is to be sent to the next position by the conveyor belt, the lifting platform descends. The second lifting and conveying roller includes a plurality of conveying rollers that can be lifted and lowered relative to the longitudinal translation device 3 and arranged in the longitudinal direction. When the second-order semi-finished product is sent into the rolling device 4, the second lifting and conveying roller rises to reduce the friction between the second-order semi-finished product and the longitudinal translation device 3. The second lifting and conveying roller is in a lowered state while waiting for the new second-order semi-finished product to arrive.

[0049] The rolling device 4 is used to roll the notch 04 of the second-order semi-finished product to obtain the finished product. The rolling device 4 is a prior art. The common rolling device in the prior art can be used, and the new rolling device 4 provided in this embodiment can also be used. The structure of the new rolling device 4 is described below.

[0050] The material receiving device 6 is used to receive the finished products sent out from the rolling device 4 .

[0051] The thermal insulation strip storage platform 5 is arranged beside the longitudinal translation device 3, and the thermal insulation strip storage platform 5 is used to store a large number of fixed-length thermal insulation strips 03.

[0052] The structure of the broken bridge aluminum is as follows Figure 3 As shown, it comprises a lower profile 01, an upper profile 02 and a heat insulation strip 03 connected between the upper profile 02 and the lower profile 01. The portion of the heat insulation strip 03 inserted into the lower profile 01 is the lower edge 031, the portion of the heat insulation strip 03 inserted into the upper profile 02 is the upper edge 032, and both the lower profile 01 and the upper profile 02 are provided with a notch 04 for the upper edge 032 and the lower edge 031 to be inserted.

[0053] Based on the thermal break aluminum production line provided by the utility model, the production steps are as follows:

[0054] S1. Prepare fixed-length lower profile 01, upper profile 02 and thermal insulation strip 03. In the traditional production line, the lower profile and the upper profile are fixed-length, that is, in sections, but the thermal insulation strip is a coil of variable length. The traditional production line inserts the thermal insulation strip into the lower profile and the upper profile and then cuts out the inserted thermal insulation strip. In the present production line, the thermal insulation strip 03 is fixed-length, that is, the thermal insulation strip 03 needs to be cut into sections in advance.

[0055] S2, such as Figure 4 As shown, the heat insulation strip 03 is clamped at the first toothed striping station by a clamp 06 (i.e., the clamp 23 described below). Preferably, the clamped portion of the heat insulation strip 03 is the upper edge 032 of the front end 033. Then, the lower profile 01 is passed through the first toothed striping station, wherein the lower profile 01 is placed with the notch 04 facing upward and the height of the notch 04 is consistent with the height of the lower edge 031 of the heat insulation strip 03. In the process of the lower profile 01 passing through the first toothed striping station, the notch 04 is first toothed upward and then inserted into the lower edge 031 of the heat insulation strip 03 from front to back, thereby obtaining Figure 5 The first-order semi-finished product shown in FIG. The upper toothing means that most of the toothing cutter 05 is higher than the lower profile 01 .

[0056] S3, loosen the clamping of the heat insulation strip 03 and move the first-stage semi-finished product to the position opposite to the second toothed sleeve strip station. In order to improve the convenience of production, Figure 6 As shown, after obtaining the first-stage semi-finished product, the front end 033 of the heat insulation strip 03 is extended out of the lower profile 01; this is to facilitate the clamping point of the clamp 06 when the profile 02 is subsequently put on.

[0057] S4, such as Figure 7 As shown, the thermal insulation strip 03 in the first-stage semi-finished product is clamped by a chuck 06 at the second toothing strip station. Preferably, the clamped portion of the thermal insulation strip 03 is the lower edge 031 of the front end 033. Then, the upper profile 02 is passed through the second toothing strip station, wherein the upper profile 02 is placed with the notch 04 facing downward and the height of the notch 04 is consistent with the height of the upper edge 032 of the thermal insulation strip 03. In the process of the upper profile 02 passing through the second toothing strip station, the notch 04 is first toothed downward and then inserted into the upper edge 032 of the thermal insulation strip 03 from front to back, thereby obtaining a second-stage semi-finished product. The meaning of the lower toothing is that most of the toothing knife 05 is lower than the upper profile 02. After the above steps, the following is obtained. Figure 6 The second-order semi-finished product shown.

[0058] S5. Release the clamping of the thermal insulation strip 03 and make the second-stage semi-finished product face the rolling station. Preferably, align at least one end of the lower profile 01, the thermal insulation strip 03 and the upper profile 02 with each other, so that the lower profile 01, the thermal insulation strip 03 and the upper profile 02 at one end of the second-stage semi-finished product are all aligned, while the other end is inevitably misaligned, and the other end can be cut neatly after the finished product is obtained.

[0059] S6. The second-stage semi-finished product is passed through a rolling station. During the process of passing through the rolling station, the vertical heads of all the notches 04 of the second-stage semi-finished product are rolled to clamp the thermal insulation strip 03 to obtain a finished product.

[0060] Based on the above steps, during the production process of this type of thermally-insulated aluminum production line, the profiles only need to be fed and translated in the original placement posture, and there is no need to flip the profiles during the entire process, which simplifies the production process and reduces the labor intensity of the staff, thereby reducing the production cost. At the same time, when the upper profile 02 is put on, the traditional method of inserting the thermal insulation strip 03 into the profile is replaced with a method of putting the profile into the thermal insulation strip 03. In this method, the thermal insulation strip 03 always provides support for the upper profile 02, so that the upper profile 02 can be put on smoothly, the profile will not jump during the process of putting on the strip, the noise is small and the safety is high.

[0061] In the actual production process, different types of thermally-insulated aluminum profiles have different heights, the heights of the thermal insulation strips are also different, and the corresponding heights of each work station are also different. Therefore, this embodiment further proposes a step for adjusting the working height.

[0062] In this embodiment, the feeding height of the lower profile 01 is used as a reference, wherein the feeding height refers to the height of the conveying surface when feeding the lower profile 01, and the reference means that other working heights are based on the conveying surface of the lower profile 01. Of course, taking the conveying surface of the lower profile 01 as a reference does not mean that the height of the conveying surface of the lower profile 01 remains unchanged relative to the ground. The conveying surface of the lower profile 01 can also be raised and lowered relative to the ground. When the conveying surface of the lower profile 01 is raised and lowered, that is, the reference is changed, other working heights also need to be changed in the same way. Of course, the best solution is that the height of the conveying surface used to convey the lower profile 01 remains unchanged during the production process, and the reference that remains unchanged is the ground.

[0063] The steps for adjusting other working heights are as follows: adjusting the height of the toothing operation in the first toothing sleeve strip station according to the height of the notch 04 of the lower profile 01; adjusting the clamping height of the thermal insulation strip 03 in the first toothing sleeve strip station according to the standard that the lower edge 031 of the thermal insulation strip 03 is equal to the notch 04 of the lower profile 01; adjusting the feeding height of the upper profile 02 according to the standard that the notch 04 of the upper profile 02 is equal to the upper edge 032 of the thermal insulation strip 03 in the first-order semi-finished product; adjusting the height of the toothing operation in the second toothing sleeve strip station according to the height of the notch 04 of the upper profile 02; adjusting the clamping height of the thermal insulation strip 03 in the second toothing sleeve strip station according to the standard that the thermal insulation strip 03 in the first-order semi-finished product is clamped firmly and does not block the sleeve of the upper profile 02; adjusting the rolling height of the rolling station according to the height of each vertical head in the second-order semi-finished product. Based on the above steps and standards, different types of thermal break aluminum can be quickly adapted, and the adjustment is convenient and efficient.

[0064] Based on the above-mentioned structural setting, in order to reduce the structural complexity of the production line, it is preferred to equip staff to perform partial operations, specifically, to configure one person next to the first toothed strip machine 21, whose job is to pick up the insulation strip 03 from the insulation strip storage table 5 and clamp it to the first toothed strip machine 21. It is also necessary to configure one person next to the first toothed strip machine 21, whose job is to clamp the first-order semi-finished insulation strip 03 to the second toothed strip machine 22. At the same time, this staff member also pushes the second-order semi-finished product into the rolling device 4, and the rolling device 4 will automatically pull away the second-order semi-finished product during rolling.

[0065] In this embodiment, the conveying surface of the first feed table 11 is used as a reference; the height of the conveying surface of the second feed table 12 is adjustable; the height of the conveying surface of the first open-toothed sleeve machine 21 is fixed, that is, Fig.13 The height of the first toothed strip-threading conveying roller 211 is fixed, and the toothing height and clamping height of the first toothed strip-threading machine 21 are adjustable; the height of the conveying surface of the second toothed strip-threading machine 22 is adjustable, and the toothing height and clamping height of the second toothed strip-threading machine 22 are adjustable; the height of the conveying surface of the rolling device 4 is fixed, that is, Fig.17 The height of the rolling conveying roller 42 is fixed, and the rolling height of the rolling device 4 is adjustable. According to the above structural setting, it can quickly adapt to different types of broken bridge aluminum, and it is convenient to adjust during adjustment and has high adjustment efficiency.

[0066] In this embodiment, if Figures 9 to 12As shown, a conveying platform 13 is arranged on the lateral side of the second feed platform 12, and the conveying direction of the conveying platform 13 is longitudinal. Preferably, the conveying components of the conveying platform 13 are multiple parallel conveyor belts, and the conveying components of the second feed platform 12 are multiple rollers arranged along a straight line. At one end of the conveying platform 13 close to the second feed platform 12, at least two sets of synchronous positioning mechanisms 14 and at least two sets of synchronous turning conveying mechanisms 15 are arranged. The positioning mechanism 14 is used to position the profile in the conveying process at the waiting position of the conveying platform 13, and the turning conveying mechanism 15 is used to lift the profile from the waiting position and transfer it to the second feed platform 12 along a vertical arc trajectory, and the trajectory turns over the gap between the conveying platform 13 and the second feed platform 12. When in use, the end of the conveying table 13 away from the second feeding table 12 is connected to the external temporary storage table. The temporary storage table is used to store a large number of profiles. The profiles on the temporary storage table are sent to the conveying table 13 and conveyed in the direction of the second feeding table 12; when the upper profile 02 reaches the material position to be taken, it is blocked by the positioning mechanism 14 and stops moving forward, and then the overturning conveying mechanism 15 transfers the upper profile 02 to the second feeding table 12; because the trajectory of the overturning conveying mechanism 15 is a vertical arc line, it uses a leaping method to cross the gap between the conveying table 13 and the second feeding table 12. Therefore, even if the second feeding table 12 is raised or lowered, the upper profile 02 can be successfully transferred to the second feeding table 12, and it has strong adaptability when used.

[0067] In this embodiment, the positioning mechanism 14 can adjust its longitudinal position on the second feed table 12. During use, since the motion trajectory of the flip arm 152 is a vertical arc, the position (referring to the longitudinal position) of the second feed table 12 receiving the profile will also change after the second feed table 12 is lifted. If the profile deviates too much from the middle of the second feed table 12 after being placed on the second feed table 12, the profile will not be able to align with the first toothed sleeve machine 21 when the second feed table 12 is loaded, which will affect the normal production. For this reason, the position of the positioning mechanism 14 is adjustable in this embodiment. Preferably, the structure for realizing the position adjustment of the positioning mechanism 14 is a handwheel installed on the conveying table 13 and a screw connected to the handwheel, and the screw is threadedly connected to the positioning mechanism 14.

[0068] In this embodiment, the flipping conveying mechanism 15 includes a mounting plate 151, a flipping arm 152, a flipping power mechanism 153, a support plate 154 and a horizontal holding mechanism 155; the mounting plate 151 is mounted on the conveying platform 13, the flipping arm 152 is rotatably connected to the mounting plate 151, the flipping power mechanism 153 is used to drive the flipping arm 152 to rotate, the support plate 154 is rotatably connected to the end of the flipping arm 152, and the horizontal holding mechanism 155 is used to keep the supporting surface of the support plate 154 in a horizontal state during the flipping process of the flipping arm 152; the above structure is used to realize the function of the flipping conveying mechanism 15, and the supporting surface of the support plate 154 is kept in a horizontal state to ensure that the profile can be held and transferred in the same posture, and the support plate 154 cannot be skewed, otherwise the profile will fall. The second feeding platform 12 is provided with an avoidance gap 121 for the flipping arm 152 and the support plate 154 to pass through. The avoidance gap 121 is provided to allow the flip arm 152 and the support plate 154 to pass downward. After passing through, the profile on the support plate 154 is handed over to the conveying platform 13 to complete the transfer of the profile. Preferably, the mounting plate 151 is fixedly mounted with an axle seat 1511, and the flip power mechanism 153 includes a power shaft passing through the axle seat 1511, and the power shaft is circumferentially fixedly connected to the flip arm 152. The power shaft and the flip arm 152 are circumferentially fixed in a manner that a keyway and a key structure are provided between the two, so that when the power shaft rotates, the flip arm 152 rotates together. The function of the flip power mechanism 153 is realized based on the above structure. The horizontal holding mechanism 155 includes a fixed pulley 1551 fixedly connected to the shaft seat 1511, a driven pulley rotatably connected to the flip arm 152, and a belt 1552 meshed between the fixed pulley 1551 and the driven pulley. The fixed pulley 1551 is fixedly connected to the shaft seat 1511 by setting a keyway and a key structure between the two. Since the shaft seat 1511 cannot move relative to the mounting plate 151, the fixed pulley 1551 cannot rotate relative to the mounting plate 151. The driven pulley is circumferentially fixedly connected to the support plate 154, and the support plate 154 is fixedly connected to the driven pulley by screws. The flip arm 152 is also provided with a tightening device for tightening the belt 1552. The tightening device includes an adjustment plate that is adjustably connected to the flip arm 152 and a roller that is rotatably connected to the adjustment plate, and the roller abuts against the belt 1552. The function of the horizontal holding mechanism 155 is realized based on the above structure.

[0069] In this embodiment, if Figures 13 to 16As shown, the first toothed strip machine 21 and the second toothed strip machine 22 both include a clamp 23; the clamp 23 includes a seat body 231, a fixed clamping plate 232 fixed to the seat body 231, a sliding clamping plate 233 slidably connected to the seat body 231, and a telescopic cylinder 234 connected to the seat body 231 and used to drive the sliding clamping plate 233 to slide. The sliding clamping plate 233 slides in the transverse direction, and there is a clamping space between the sliding clamping plate 233 and the fixed clamping plate 232. The clamping space is also a space for clamping the heat insulation strip 03, and the rear end opening 235 of the clamping space is used for inserting the profile into the clamping space. The front end 033 of the clamping space is provided with a sensing plate 236, and the side of the clamping space away from the seat body 231 is an open opening 237, which refers to the opening for the main body of the heat insulation strip 03 to extend out of the clamp 23. The open opening 237 of the clamp 23 in the first toothed sleeve machine 21 faces downward, that is, the clamp 23 in the first toothed sleeve machine 21 clamps the heat insulation strip 03 from top to bottom, and the open opening 237 of the clamp 23 in the second toothed sleeve machine 22 faces upward, that is, the clamp 23 in the second toothed sleeve machine 22 clamps the heat insulation strip 03 from bottom to top. When the staff pushes the heat insulation strip 03 into the clamping space from the rear end opening 235 and continues to push it inward until it touches the sensing plate 236, the sensing plate 236 sends a signal to the device controller, and the device controller controls the telescopic cylinder 234 to move, and the sliding clamp plate 233 and the fixed clamp plate 232 clamp the heat insulation strip 03. At least one of the clamps 23 is also provided with a clamping height adjustment mechanism 238 for adjusting the height of the seat body 231. At least one of them refers to more than one clamp 23 provided with a clamping height adjustment mechanism 238. The clamping height adjustment mechanism 238 is used to adjust the height of the clamping position of the clamp 23 to adapt to different models of thermally-insulated aluminum.

[0070] In this embodiment, if Figures 17 to 20As shown, the rolling device 4 includes a rolling frame 41, a rolling conveying roller 42 and a plurality of rolling devices 43 arranged on the rolling frame 41. The height of the rolling conveying roller 42 relative to the rolling frame 41 is fixed, and the height of the rolling device 43 relative to the rolling frame 41 is adjustable. The plurality of rolling devices 43 are arranged along the conveying direction of the rolling conveying roller 42. Each rolling device 43 includes a rolling assembly 431 arranged on both sides of the rolling conveying roller 42. The rolling assembly 431 includes a rotating shaft 432 and an upper rolling wheel 433 and a lower rolling wheel 434 installed on the rotating shaft 432. At least one of the rolling assemblies 431 is configured such that both the upper rolling wheel 433 and the lower rolling wheel 434 are adjustable. The upper rolling wheel 433 is connected to the rotating shaft 432 by means of a threaded adjustment structure and can be raised and lowered relative to the rotating shaft 432. The lower rolling wheel 434 is connected to the rotating shaft 432 by means of a threaded adjustment structure and can be raised and lowered relative to the rotating shaft 432. Here, at least one of the groups means that the two groups of rolling assemblies 431 in each set of rolling devices 43 can be one of the rolling assemblies 431 set to have both the upper rolling wheel 433 and the lower rolling wheel 434 adjustable, or both of the rolling assemblies 431 set to have both the upper rolling wheel 433 and the lower rolling wheel 434 adjustable. Among them, in the case where only one of the rolling assemblies 431 is set to have both the upper rolling wheel 433 and the lower rolling wheel 434 adjustable, the other group of rolling assemblies 431 should be set to have the upper rolling wheel 433 adjustable but the lower rolling wheel 434 fixed. The structure and adjustment method of such rolling assemblies 431 are prior art, and reference can be made to Chinese invention patent application No. 2021112459545, so it will not be repeated in this application.

[0071] Preferably, in this embodiment, one of the rolling components 431 is set so that both the upper rolling wheel 433 and the lower rolling wheel 434 are adjustable, and the other rolling component 431 is set so that the upper rolling wheel 433 is adjustable but the lower rolling wheel 434 is fixed. Through the above-mentioned structural setting, the four rolling wheels in the rolling device 43 are configured as three movable and one fixed, and the height of the fixed lower rolling wheel 434 is used as a reference for the overall height of the entire rolling device 43. During production, one of the vertical heads of the broken bridge aluminum is made to face the fixed lower rolling wheel 434, and then the heights of the other three rolling wheels are adjusted so that the heights of the other three rolling wheels face the other three vertical heads. In this way, the broken bridge aluminum of different models and specifications can be quickly adapted, and the adjustment efficiency and adjustment accuracy are high.

[0072] The structure in which the upper rolling wheel 433 is adjustable relative to the rotating shaft 432 is prior art, and specific reference may be made to Chinese invention patent application 2021112459545, so it will not be described in detail in this application.

[0073] This embodiment provides a solution for realizing the lifting and lowering of the lower rolling wheel 433 relative to the rotating shaft 432. In this embodiment, the structure for lifting and lowering the lower rolling wheel 434 relative to the rotating shaft 432 is as follows: the rolling assembly 431 also includes an adjusting sleeve 435 and a sliding sleeve 436, the sliding sleeve 436 is sleeved on the rotating shaft 432, the sliding sleeve 436 is circumferentially fixed with the rotating shaft 432 and can slide along the axial direction of the rotating shaft 432, that is, when the rotating shaft 432 rotates, the sliding sleeve 436 will be driven to rotate at the same time, and the sliding sleeve 436 can only slide relative to the rotating shaft 432 but cannot rotate relative to the rotating shaft 432. The adjusting sleeve 435 is connected to the rotating shaft 432 in an axially fixed and circumferentially rotatable manner, the adjusting sleeve 435 is threadedly connected to the sliding sleeve 436, and the lower rolling wheel 434 is connected to the sliding sleeve 436. In this way, when the height of the lower rolling wheel 434 needs to be adjusted, the adjusting sleeve 435 is rotated, and the sliding sleeve 436 slides up and down by means of the threaded connection between the adjusting sleeve 435 and the sliding sleeve 436, that is, the lower rolling wheel 434 is driven to slide up and down, and the height adjustment of the lower rolling wheel 434 is completed.

[0074] In this embodiment, the sliding sleeve 436 is slidably connected to the rotating shaft 432 by means of a connection structure of a key slot and a sliding key.

[0075] In order to keep the height of the adjustment sleeve 435 relative to the rotating shaft 432 unchanged, in this embodiment, the rotating shaft 432 is provided with a circumferential positioning groove 4321, the adjustment sleeve 435 is provided with a positioning hole 4351 connected to the rotating shaft 432, and a positioning block 4352 is provided in the positioning hole 4351, and the positioning block 4352 partially extends into the positioning groove 4321. In this way, the positioning block 4352 is inserted into the positioning groove 4321 to limit the up and down movement of the adjustment sleeve 435, and the positioning block 4352 only extends into the positioning groove 4321 but does not press against the positioning groove 4321, so that the adjustment sleeve 435 can rotate relative to the rotating shaft 432.

[0076] In this embodiment, the adjusting sleeve 435 is provided with a locking hole 4353 connected to the sliding sleeve 436, and the locking hole 4353 is threadedly connected with a top screw 4354, and a copper pad 4355 is placed between the top screw 4354 and the sliding sleeve 436. The top screw 4354 is used to lock and unlock the adjusting sleeve 435 and the sliding sleeve 436. When it is necessary to adjust the height of the lower rolling wheel 434, the top screw 4354 is first loosened to allow the adjusting sleeve 435 to rotate relative to the sliding sleeve 436. After the lower rolling wheel 434 is adjusted to the required height, the top screw 4354 is tightened again, and the adjusting sleeve 435 and the sliding sleeve 436 are relatively fixed. In order to prevent the top screw 4354 from damaging the thread of the sliding sleeve 436, a copper pad 4355 is placed between the top screw 4354 and the sliding sleeve 436 in this embodiment. The copper pad 4355 is more easily deformed and will not damage the thread of the sliding sleeve 436 when tightened.

[0077] In this embodiment, if Fig.21As shown, a baffle 31 is provided on the side of the longitudinal translation device 3 that is far from the toothed strip device 2. The baffle 31 is opposite to the first toothed strip machine 21. A convex plate 311 is provided on the side of the baffle 31 that faces the first toothed strip machine 21. The convex plate 311 is used to abut the heat insulation strip 03 from the rear end so that the front end 033 of the heat insulation strip 03 extends out of the lower profile 01. Based on this structural setting, after obtaining a first-order semi-finished product, a section of the semi-finished product is pushed toward the baffle 31, and the convex plate 311 on the baffle 31 abuts against the heat insulation strip 03 so that the front end 033 of the heat insulation strip 03 extends out of the lower profile 01, and the following is obtained. Figure 4 The structure shown.
