A conveyor heating device for belt pulley products

Abstract

This utility model relates to a conveying and heating device for pulley products, belonging to the field of automotive parts manufacturing technology. It includes an upper housing for heating the product, mounted on a support base. A conveyor belt for conveying the product is mounted on the support base. A curtain is provided at the side entrance of the upper housing, and the distance between the curtain and the conveyor belt is adjustable. This application uses a fine-tuning cylinder to control the height of the adjustable curtain, precisely matching the thickness of a single layer of sheet material. When stacked sheets pass through, the curtain pushes down the upper layer, forcing single-layer, sheet-by-sheet feeding. This avoids insufficient heating of the sheet material contact surface from the source, eliminating the risk of deformation / cracking caused by incomplete stress relief. Furthermore, in this application, the curtain applies resistance to the vertical long side, causing it to automatically flip to a standard vertical posture with the short side, eliminating the need for pre-adjustment and solving the pain point of requiring manual correction for irregularly shaped parts.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a conveying and heating device for pulley products. Background Technology

[0002] Belt pulleys are core components in mechanical transmission systems, primarily used to transmit power, change speed, or change direction. The installation stability of belt pulleys is essential for maintaining their accuracy during operation; therefore, belt pulleys include mounting plates to ensure their stability.

[0003] The mounting plates include flat plates and L-shaped plates. During the production of the mounting plates, in order to ensure the quality of the mounting plates, they need to be heat-treated to eliminate their internal stress. That is, the mounting plates are annealed after welding to prevent deformation during service, thereby further avoiding deformation and cracking problems of the mounting plates.

[0004] Based on the above solution, when heating the mounting plate, the mounting plates may stack up, causing the stacked surfaces of the mounting plates to come into contact with each other, which further affects the heating quality of the mounting plates. This can lead to deformation or cracking of the mounting plates during use, affecting the stability of the pulley products during transportation. Utility Model Content

[0005] The technical problem solved by this utility model is to solve the problem of poor heating effect caused by the stacking of mounting plates when heat treating mounting plates in the prior art.

[0006] This utility model can be achieved through the following technical solution: a conveying and heating device for belt pulley products, including an upper housing for heating the product, the upper housing being mounted on a support base, a conveyor belt for conveying the product being provided on the support base, including a curtain provided at the side entrance of the upper housing, and the distance between the curtain and the conveyor belt being adjustable.

[0007] A further technical improvement of this utility model is that the curtain is fixedly installed at the output end of the fine-tuning cylinder, and the fine-tuning cylinder is fixedly installed inside the upper chassis.

[0008] A further technical improvement of this utility model is that the conveyor belt is a metal mesh chain conveyor belt.

[0009] A further technical improvement of this utility model is that a top motor is fixed on the top of the upper chassis, and an internal fan is provided at the output end of the top motor, with the internal fan located inside the upper chassis.

[0010] A further technical improvement of this utility model is that a heating base plate is fixed inside the upper casing, gas passage slots are evenly opened on the heating base plate, and a heating wire is provided at the bottom of the heating base plate.

[0011] A further technical improvement of this utility model is that the curtain has a double-layer structure, and the side of the curtain facing the inside of the upper chassis is an insulation board.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This application controls the height of the adjustable baffle curtain through a fine-tuning cylinder to precisely match the thickness of a single layer of board. When stacked boards pass through, the baffle curtain pushes down the upper layer of board, forcing the feeding of single-layer boards one by one: this avoids insufficient heating of the board contact surface from the source and eliminates the risk of deformation / cracking caused by incomplete stress relief; in addition, in this application, the baffle curtain applies resistance to the vertical long side, causing it to automatically flip to the standard posture of the short side being vertical, eliminating the pre-adjustment process and solving the pain point of needing manual correction for irregularly shaped parts (reducing labor intensity by 40%+).

[0014] 2. This application uses a control panel to link a fine-tuning cylinder, which can complete the curtain height switching within 3 seconds. It can handle various pulley mounting plates such as flat plates (thickness 0.5-10mm) and L-shaped parts (vertical edge ≤150mm). It replaces manual sorting with mechanical error prevention. Through stacking blocking + intelligent correction + thermal field optimization triple technology, it achieves zero defects in annealing quality, while reducing energy consumption by more than 30%, providing a reliable basic component guarantee for high-precision pulleys.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-7 As shown, a conveying and heating device for a pulley product includes a support base 4, on which an upper housing 1 for heating the product is fixed. A conveyor belt 5 for product entry and exit is provided on the support base 4. The conveyor belt 5 is a mesh chain conveyor belt, which is adapted to the high temperature of product heating in this application. That is, in use, the product is placed on the conveyor belt 5, and the conveyor roller drives the conveyor belt 5 to move, so that the product can enter the interior of the upper housing 1 and be heated by the upper housing 1.

[0026] A control panel 2 is fixed on the upper housing 1. The control panel 2 is used to control the moving speed of the conveyor belt 5, that is, to control the rotation speed of the conveyor roller, through signal transmission. At the same time, the control panel 2 also integrates buttons for controlling the internal temperature of the upper housing 1, so that the internal temperature of the upper housing 1 is controllable.

[0027] Furthermore, when the upper casing 1 is initially started, since the temperature inside the upper casing 1 is mainly distributed near the heating wire, in order to achieve uniform heat distribution, a top motor 3 is fixedly installed on the top of the upper casing 1. A heating cavity 8 is opened inside the upper casing 1, and an internal fan 7 is fixedly installed at the output end of the top motor 3. The internal fan 7 is located inside the heating cavity 8. A heating base plate 10 is fixedly installed on the support base 4, and gas passage slots 9 are evenly opened on the heating base plate 10. A heating wire for heating function is set at the bottom of the heating base plate 10 to ensure the temperature inside the heating cavity 8. In use, the gas passage slots 9 are used to allow gas to pass through. An air circulation cavity is set at the bottom of the conveyor belt 5. The top motor 3 drives the internal fan 7 to rotate relatively slowly, so that the air inside the heating cavity 8 flows slowly during the initial heating process, so that the hot air is evenly distributed inside the heating cavity 8 at the beginning. This allows the heating cavity 8 to quickly achieve uniform heat distribution and ensure the heating effect on the product.

[0028] Furthermore, a baffle curtain 6 is installed at the entrance of the upper housing 1 to shield and adjust the products. The height of the baffle curtain 6 is adjustable. When the products are placed on the conveyor belt 5, the presence of the baffle curtain 6 restricts products that do not meet the height requirements, preventing non-compliant products from entering the upper housing 1 and causing uneven heating. At the same time, the baffle curtain 6 has a double-layer structure. The side of the baffle curtain 6 facing the inside of the upper housing 1 is an insulation board, while the side of the baffle curtain 6 away from the inside of the upper housing 1 is made of metal, reducing the temperature loss caused by the baffle curtain 6. The double-layer structure also allows the baffle curtain 6 to have a certain width, so it has a certain stability and can better handle the processed parts.

[0029] Specifically, a fine-tuning cylinder 13 is fixedly installed inside the upper housing 1. The baffle 6 is fixedly installed at the output end of the fine-tuning cylinder 13. In use, the height of the baffle 6 is controlled by the fine-tuning cylinder 13, so that the entrance of the corresponding height is opened according to the product of different height. That is, the baffle 6 is moved downward by the fine-tuning cylinder 13 until the height of the baffle 6 matches the height of the product. The single board 12 can directly enter the interior of the upper housing 1 through the distance between the baffle 6 and the conveyor belt 5. The upper board of the stacked board 11 is blocked by the baffle 6. When the friction between the conveyor belt 5 and the lower board of the stacked board 11 is large, the baffle 6 will gradually push the board above the stacked board 11 down, so that the board above the stacked board 11 can detach from the lower board until it falls onto the conveyor belt 5. This allows the stacked board 11 to enter the interior of the upper housing 1 under the action of the baffle 6, avoiding the problem of uneven heating caused by the stacking of boards.

[0030] In another embodiment of this application, when the workpiece to be heated is an L-shaped workpiece 14, and the L-shaped workpiece 14 has a long side and a short side, when the short side is vertically upward, the L-shaped workpiece 14 can directly enter the interior of the upper housing 1. When the long side is vertically upward and the long side is to the left of the short side, under the restriction of the curtain 6, it will fall and rotate to a certain extent until it rotates to ninety degrees and becomes a state where the short side is vertically upward. This can reduce heat loss while limiting the height between the curtain 6 and the conveyor belt 5, and at the same time ensure the entry of the L-shaped workpiece 14. Therefore, in this application, when the L-shaped workpiece 14 enters, it is necessary to ensure that the vertical side is to the left of the horizontal side, without needing to detect and correct the long and short sides of the L-shaped workpiece 14, thus reducing the labor intensity of the workers on site.

[0031] In use, when heating the sheet material, the sheet material is placed on the conveyor belt 5. The fine-tuning cylinder 13 moves the curtain 6 downward until the height of the curtain 6 matches the height of the product. The single sheet material 12 can directly enter the interior of the upper housing 1 through the distance between the curtain 6 and the conveyor belt 5. The upper sheet material of the stacked sheet material 11 is blocked by the curtain 6. When the friction between the conveyor belt 5 and the lower sheet material of the stacked sheet material 11 is large, the curtain 6 will gradually push the upper sheet material of the stacked sheet material 11 down, so that the upper sheet material of the stacked sheet material 11 can detach from the lower sheet material until it falls onto the conveyor belt 5. This allows the stacked sheet material 11 to enter the interior of the upper housing 1 under the action of the curtain 6, avoiding the problem of uneven heating caused by the stacking of sheet materials.

[0032] When the L-shaped workpiece 14 is heated, if the short side is vertically upward, the L-shaped workpiece 14 can directly enter the upper housing 1. If the long side is vertically upward and the long side is to the left of the short side, it will fall and rotate under the restriction of the curtain 6 until it rotates to ninety degrees and the short side is vertically upward. This reduces heat loss while limiting the height between the curtain 6 and the conveyor belt 5, and also ensures the entry of the L-shaped workpiece 14. Therefore, in this application, when the L-shaped workpiece 14 enters, it is necessary to ensure that the vertical side is to the left of the horizontal side, without needing to check and correct the long and short sides of the L-shaped workpiece 14, thus reducing the labor intensity of the workers on site.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
