[0002] Plastic crates, especially turnover boxes and logistics boxes made of thermoplastic plastics such as polypropylene (PP) or high-density polyethylene (HDPE), are widely used in many industries such as logistics transportation, warehousing management, agricultural production, and food processing due to their advantages such as light weight, durability, corrosion resistance, and recyclability.

[0003] In the production process of plastic sheet boxes, the connection of plastic sheets is mainly achieved by heating to melt the joint area and then bonding them together. Current heating methods primarily involve using a hot air welding gun, followed by manual assembly.

[0004] However, this method demands a very high level of skill from the operators. The quality of the welding depends excessively on the operator's experience, which not only consumes a lot of manpower but is also inefficient. Utility Model Content

The first threaded sleeve and the second threaded sleeve are respectively sleeved on both ends of the double-ended screw. The guide rod is mounted on the bracket, and the first guide sleeve and the second guide sleeve are slidably mounted on the guide rod. The first guide sleeve is fixedly connected to the first threaded sleeve, and the second guide sleeve is fixedly connected to the second threaded sleeve. The first guide sleeve is fixedly connected to the first carrier plate, and the second guide sleeve is fixedly connected to the second carrier plate.

[0015] Preferably, the second lifting mechanism is a cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a heating and welding device for plastic sheet boxes. Two plastic sheets to be joined are placed on a first carrier plate and a second carrier plate, respectively, ensuring both sheets are aligned and in contact with a heating strip. A first pressing mechanism and a second pressing mechanism then press the two sheets together. The heating strip is activated to heat the joint, melting the plastic sheets. A moving mechanism then moves the first and second carrier plates away from each other, detaching the sheets from the heating strip. A first lifting mechanism then lowers the heating strip. Finally, a moving mechanism moves the first and second carrier plates closer together, bringing the joint of the two sheets into contact. After cooling, the plastic sheets are joined.

[0017] By pre-aligning the two plastic plates with the heating strip, rapid alignment of the plastic plates can be achieved, ensuring subsequent connection accuracy. After heating, the first and second carrier plates are moved away from each other, causing both plastic plates to detach from the heating strip. This prevents the heating strip from affecting the plastic plates during descent and causing bending deformation, effectively ensuring processing accuracy and efficiency. Attached Figure Description

[0020] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] This embodiment provides a heating and welding device for plastic plate boxes, including a support 100, a first lifting mechanism 1, a moving mechanism 2, a first carrier plate 3, a second carrier plate 4, and a heating strip 5.

[0022] The first lifting mechanism 1 is mounted on the bracket 100, and the heating strip 5 is mounted on the lifting end of the first lifting mechanism 1; For example, see Figure 1 The first lifting mechanism 1 is a cylinder. A mounting plate is fixed to the side wall of the bracket 100, and the first lifting mechanism 1 is fixed to the mounting plate with its telescopic end facing upwards. The heating strip 5 is fixed to the telescopic end of the first lifting mechanism 1, and the heating strip 5 can move up and down through the first lifting mechanism 1. The heating strip 5 is an electric heating strip, which can heat up when powered on.

[0023] The moving mechanism 2 is mounted on the support 100 and is used to drive the first carrier plate 3 and the second carrier plate 4 to move. For example, see Figure 1 When the heating strip 5 is at a preset height, the first carrier plate 3 and the second carrier plate 4 are located on the left and right sides of the heating strip 5, respectively.

[0024] For example, the moving mechanism 2 can include two sets of X-axis moving mechanisms. The first set of X-axis moving mechanisms can drive the first carrier plate 3 to move left and right, and the second set of X-axis moving mechanisms can drive the second carrier plate 4 to move left and right.

[0025] The first carrier plate 3 is used to place the plastic plate. The first carrier plate 3 is provided with a first mounting bracket 6. The first mounting bracket 6 is provided with a first pressing mechanism 7. The first pressing mechanism 7 is used to press the plastic plate on the first carrier plate 3. For example, see Figure 1The first plastic plate 10 is placed on the first carrier plate 3, and then the first pressing mechanism 7 presses the first plastic plate 10 down, so that the first plastic plate 10 and the first carrier plate 3 remain relatively fixed. When the first carrier plate 3 is moved by the moving mechanism 2, the first plastic plate 10 can be moved synchronously.

[0026] The second carrier plate 4 is used to place the plastic plate. The second carrier plate 4 is provided with a second mounting bracket 8. The second mounting bracket 8 is provided with a second pressing mechanism 9. The second pressing mechanism 9 is used to press the plastic plate on the second carrier plate 4. For example, see Figure 1 The second plastic plate 11 is placed on the second carrier plate 4, and then the second pressing mechanism 9 presses the second plastic plate 11 down, so that the second plastic plate 11 and the second carrier plate 4 remain relatively fixed. When the moving mechanism 2 moves the second carrier plate 4, it can drive the second plastic plate 11 to move synchronously.

[0027] Based on the above structure, the plastic plate box heating and welding device provided in this embodiment moves the heating strip 5 to a preset height position through the first lifting mechanism 1, then places the first plastic plate 10 on the first carrier plate 3, and the second plastic plate 11 on the second carrier plate 4. By adjusting the positions of the two plastic plates, both plastic plates are simultaneously aligned and in contact with the heating strip 5. Figure 1 Then, the first pressing mechanism 7 and the second pressing mechanism 9 respectively press the two plastic plates together, and the heating strip 5 is turned on to heat them, so that the joint between the two plastic plates melts. Then, the moving mechanism 2 drives the first carrier plate 3 and the second carrier plate 4 to move away from each other, as... Figure 5 This causes both plastic plates to detach from the heating strip 5, and then the heating strip 5 is driven to descend by the first lifting mechanism 1, as shown below. Figure 6 Finally, the moving mechanism 2 drives the first carrier plate 3 and the second carrier plate 4 to move closer together, as shown in the image. Figure 7 This causes the two plastic sheets to come into contact at the joint, and after cooling, the plastic sheets are successfully joined.

[0028] By pre-aligning the two plastic plates with the heating strip 5, rapid alignment and leveling of the plastic plates can be achieved, ensuring the accuracy of subsequent connections. After heating, the first carrier plate 3 and the second carrier plate 4 move away from each other, causing both plastic plates to detach from the heating strip 5. This prevents the heating strip 5 from affecting the plastic plates as it descends, thus avoiding bending deformation and effectively ensuring processing accuracy and efficiency.

[0029] Based on the above technical solutions, in the technical solution provided in this embodiment, the moving mechanism 2 includes a motor 201, a double-headed screw 202, a first threaded sleeve 203, a second threaded sleeve 204, a guide rod 205, a first guide sleeve 206, and a second guide sleeve 207. The double-ended screw 202 is rotatably mounted on the bracket 100, and the motor 201 is used to drive the double-ended screw 202 to rotate. The first threaded sleeve 203 and the second threaded sleeve 204 are respectively sleeved on both ends of the double-ended screw 202. For example, see Figure 2 A rotating ring is fixedly mounted on the side wall of the bracket 100. A double-ended screw 202 is arranged in the left-right direction. A rotating shaft is coaxially fixed to the right end of the double-ended screw 202, and the rotating shaft is rotatably mounted inside the rotating ring via a bearing. A platform is fixedly mounted on the side wall of the bracket 100, and a motor 201 is fixed on the platform. The power output end of the motor 201 is coaxially fixed to the double-ended screw 202. The motor 201 can drive the double-ended screw 202 to rotate. A first threaded sleeve 203 is threadedly fitted onto the left end of the double-ended screw 202, and a second threaded sleeve 204 is threadedly fitted onto the right end of the double-ended screw 202.

[0030] The guide rod 205 is mounted on the bracket 100. The first guide sleeve 206 and the second guide sleeve 207 are slidably mounted on the guide rod 205. The first guide sleeve 206 is fixedly connected to the first threaded sleeve 203, and the second guide sleeve 207 is fixedly connected to the second threaded sleeve 204. The first guide sleeve 206 is fixedly connected to the first carrier plate 3, and the second guide sleeve 207 is fixedly connected to the second carrier plate 4. For example, see Figure 2 The guide rod 205 is fixed to the side wall of the bracket 100 and is arranged in the left-right direction. The first threaded sleeve 203, the first guide sleeve 206, and the first carrier plate 3 are fixed as one piece. The second threaded sleeve 204, the second guide sleeve 207, and the second carrier plate 4 are fixed as one piece. When the double-headed screw 202 is driven to rotate by the motor 201, the first threaded sleeve 203, the first guide sleeve 206, and the first carrier plate 3 can be driven to move left and right, and the second threaded sleeve 204, the second guide sleeve 207, and the second carrier plate 4 can be driven to move left and right, and the movement directions of the first carrier plate 3 and the second carrier plate 4 are opposite.

[0031] That is, the motor 201 can drive the first carrier plate 3 and the second carrier plate 4 to move synchronously, thereby ensuring the synchronous movement of the two plastic plates and effectively ensuring processing efficiency and accuracy.

[0032] The first carrier plate 3 is slidably connected to the top of the bracket 100, which can ensure the stability of the first carrier plate 3 when it moves.

[0033] Similarly, the second carrier plate 4 slides into contact with the top of the bracket 100, which can ensure the stability of the second carrier plate 4 when it moves.

[0034] In the technical solution provided in this embodiment, the first pressing mechanism 7 includes a second lifting mechanism 701 and a pressing plate 702. The second lifting mechanism 701 is disposed on the first mounting frame 6, and the pressing plate 702 is disposed on the lifting end of the second lifting mechanism 701. The first pressing mechanism 7 also includes a base plate 703 and a spring 704; The substrate 703 is disposed at the lifting end of the second lifting mechanism 701, and the pressing plate 702 is located below the substrate 703. The pressing plate 702 and the substrate 703 are connected by a spring 704. For example, see Figure 3 Two second lifting mechanisms 701 are fixed on the first mounting bracket 6. The second lifting mechanism 701 is a cylinder, and the telescopic end of the second lifting mechanism 701 faces downward. The substrate 703 is fixed to the telescopic ends of the two second lifting mechanisms 701 at the same time. By the synchronous extension and retraction of the two second lifting mechanisms 701, the substrate 703 can be driven to move up and down.

[0035] For example, the pressing plate 702 is located below the substrate 703 and above the first carrier plate 3. Both the pressing plate 702 and the substrate 703 are horizontally positioned. The pressing plate 702 and the substrate 703 are connected by four sets of springs 704. When the substrate 703 is driven to move up and down by the second lifting mechanism 701, the pressing plate 702 can also move up and down. When the pressing plate 702 descends to contact the plastic plate on the first carrier plate 3, it can exert a pressing effect on the plastic plate. As the substrate 703 continues to move down, the springs 704 are compressed. The greater the pressure of the pressing plate 702 on the plastic plate, the higher the stability of the plastic plate.

[0036] This avoids the direct, rigid contact between the substrate 703 and the plastic sheet during pressing, which could cause deformation of the plastic sheet and effectively ensure processing accuracy. It also prevents processing failures due to errors, such as insufficient descent distance of the substrate 703 resulting in failure to contact the plastic sheet, or excessive descent distance causing dents in the plastic sheet.

[0037] Furthermore, the bottom end of the substrate 703 is provided with an outer cylinder 706, the top end of the pressing plate 702 is provided with an inner cylinder 705, and the outer cylinder 706 is slidably sleeved on the outside of the inner cylinder 705; both the inner cylinder 705 and the outer cylinder 706 are located inside the spring 704. For example, four sets of outer cylinders 706 are fixedly provided at the bottom of the base plate 703, and four sets of inner cylinders 705 are fixedly provided at the top of the pressing plate 702. The inner cylinders 705 correspond one-to-one with the outer cylinders 706, and the outer cylinders 706 are slidably sleeved on the outside of the corresponding inner cylinders 705. This can improve the stability of the pressing plate 702 and prevent the pressing plate 702 from shaking or deviating. This, in turn, improves the pressing accuracy.

[0038] In the technical solution provided in this embodiment, see [link to relevant documentation]. Figure 4 The structure of the second pressing mechanism 9 can be the same as that of the first pressing mechanism 7, and will not be described in detail here.

[0039] In the technical solution provided in this embodiment, see [link to relevant documentation]. Figure 8The bracket 100 can be a box-type structure with an open top. The top of the side wall of the box-type structure has an observation port 12, which allows staff to observe the internal situation and can also be used for power supply lines to pass through.
