Description

Technical Field

[0001] This application relates to the technical field of material conveying, and in particular to a feeding and discharging conveying device for a vertical baking oven. Background Technology

[0002] In vertical ovens, the loading and unloading of baking trays are mostly accomplished using conveyor belts. Specifically, during loading, the baking tray is placed in a designated position and then transported horizontally to the target position by the conveyor belt before entering the vertical oven's longitudinally moving lifting device. During unloading, the longitudinally moving lifting device places the baking tray in a designated position, and then the conveyor belt horizontally sends it out of the vertical oven.

[0003] During the horizontal conveying process, the conveyor belt will move the baking tray horizontally. As a result, the products placed on the baking tray may shake due to their fluidity and the conveyor belt, which may affect the appearance of the products on the baking tray. Therefore, further improvement is needed. Utility Model Content

[0004] To address the above problems, this application provides a feeding and discharging conveying device for a vertical baking oven.

[0005] This application provides a feeding and discharging conveying device for a vertical baking oven, which adopts the following technical solution: A feeding and discharging conveying device for a vertical baking oven includes a frame passing through the baking oven, a transmission belt wound around the frame, and a drive mechanism disposed on the frame to drive the transmission belt to convey food. The transmission belt is used to convey baking trays. Support mechanisms for supporting the baking trays are disposed on both sides of the frame. The support mechanisms include support strips symmetrically disposed on both sides of the frame. The length direction of the support strips is parallel to the length direction of the frame. The sidewalls of the baking trays slide in contact with the sidewalls of the two support strips that are close to each other.

[0006] By adopting the above technical solution, the support mechanisms set on both sides of the frame can support the baking tray during the conveyor belt transport process. The support bars of the support mechanism are symmetrically arranged on both sides of the frame, and their length direction is parallel to the length direction of the frame. The side wall of the baking tray slides in contact with the side wall of the two support bars, which can reduce the shaking and deviation of the baking tray during the transport process, ensure stable transport of the baking tray, reduce the impact of the shaking of the baking tray on the fluid products inside, and improve the appearance quality of the products in the baking tray.

[0007] Preferably, the edges of the opposite sides of the baking tray extend horizontally outward with abutment strips, which overlap the upper surface of the support strips.

[0008] By adopting the above technical solution, an abutment strip is provided to abut against the upper surface of the support strip, ensuring the baking tray remains stable when conveyed by the feeding and discharging conveyor device. Preferably, the support mechanism further includes an adjustment component for adjusting the spacing between the two support strips.

[0009] By adopting the above technical solution, the spacing between the two support bars can be adjusted using the adjustment component during the baking pan conveying process, so that the support bars can be adapted to baking pans of different sizes, thereby enhancing the versatility and applicability of the feeding and discharging device for baking pans of different specifications and enabling better support of the baking pans.

[0010] Preferably, the adjustment assembly includes a fixed base fixed to the frame, a first slider slidably connected to the fixed base along the width direction of the frame, and a first limiting member for limiting the sliding of the first slider, wherein the first slider is disposed on the lower surface of the support strip.

[0011] By adopting the above technical solution, when facing baking pans of different sizes, the first limiting member is released, allowing the first slider to slide along the width of the frame on the fixed seat, which drives the support strip to move and change the distance between the two support strips. After adjusting the appropriate distance, the first limiting member is used to restrict the sliding of the first slider. In this way, the support strip can stably support baking pans of different sizes, ensuring the stability of the baking pan during the conveying process and effectively reducing the impact on the appearance of fluid products in the baking pan caused by the shaking of the baking pan.

[0012] Preferably, the adjustment assembly includes a fixed base fixedly connected to the frame, a rotating member connected to the support bar and rotatably connected to the fixed base, and a second limiting member restricting the rotation of the support bar.

[0013] By adopting the above technical solution, the distance between the two support strips can be changed by rotating them, so that the device can adapt to baking pans of different sizes, thus enhancing the versatility and applicability of the device.

[0014] Preferably, a ball bearing is rotatably connected to the support strip, and the ball bearing abuts against the side wall of the baking pan.

[0015] By adopting the above technical solution and incorporating ball bearings, the frictional resistance between the support strip and the baking tray is reduced, making the baking tray transfer smoother.

[0016] Preferably, the support strip has an elastic buffer layer on the side wall facing the baking pan.

[0017] By adopting the above technical solution, an elastic buffer layer is set on the side wall of the support strip facing the baking tray. This layer can cushion the baking tray during the conveying process, effectively reducing the impact force generated by collision and friction between the baking tray and the support strip. This reduces the shaking of the baking tray due to excessive impact force, thereby preventing the appearance of products with a certain degree of fluidity in the baking tray from being affected by shaking. This makes the product more stable throughout the conveying process and ensures the final quality of the product. Furthermore, since the edges of the baking tray may bulge out and become arc-shaped after a period of use, there is a possibility of collision or jamming during the conveying of the baking tray. The elastic buffer layer is designed to accommodate baking trays with bulging outer edges due to long-term use, reducing the impact force generated by collision and the possibility of jamming.

[0018] Preferably, the elastic buffer layer includes several independent floating unit blocks, the support strip has an installation groove, and the floating unit block includes a spring built into the installation groove, a second slider slidably inserted into the installation groove, and an abutment plate disposed on the second slider.

[0019] By adopting the above technical solution, the elastic buffer layer is composed of several independent floating unit blocks. During the baking tray conveying process, if the baking tray shakes or has a certain size deviation, the spring can be compressed or extended, driving the second slider to slide in the mounting groove, so that the connecting plate adaptively adjusts its position and better fits the side wall of the baking tray. This not only more effectively buffers the impact and vibration of the baking tray and reduces excessive shaking of the baking tray that affects the appearance of the internal products, but also can adapt to baking trays of different sizes, enhancing the versatility and practicality of the conveying device.

[0020] In summary, this application has the following beneficial effects: 1. The support mechanisms on both sides of the frame can support the baking tray during the conveying process, reduce the shaking of the products in the baking tray caused by the conveyor belt, and avoid affecting the appearance of the products; 2. The abutment strip overlaps the upper surface of the support strip to further stabilize the baking tray, making the baking tray more stable during transportation; 3. The adjustable component allows for adjustment of the spacing between the two support bars, accommodating baking trays of different sizes for conveying. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0024] This application discloses a feeding and discharging conveying device for a vertical baking oven.

[0025] Example 1: A feeding and discharging conveying device for a vertical baking oven, as described in the reference. Figure 1 The oven includes a frame 2 passing through the baking oven 1, a transmission belt 3 wound around the frame 2, and a drive mechanism 4 mounted on the frame 2 to drive the transmission belt 3 for conveying. The baking oven 1 has an inlet and an outlet on opposite side walls for the frame 2 to pass through. The drive mechanism 4 drives the transmission belt 3 to wound around the frame 2 for conveying, thereby transporting the baking tray 11 on the transmission belt 3. The drive mechanism 4 specifically includes two rotating shafts rotatably connected to both ends of the frame 2 and a drive motor that drives one of the rotating shafts to rotate. The transmission belt 3 is wound around the two rotating shafts.

[0026] Reference Figure 1 , Figure 2Furthermore, to reduce shaking of the baking pan 11 during transport, in this embodiment, support mechanisms 5 for supporting the baking pan 11 are provided on both sides of the frame 2. The support mechanisms 5 include support strips 6 symmetrically arranged on both sides of the frame 2 and an adjustment component 7 for adjusting the distance between the two support strips 6. In this embodiment, the length direction of the support strips 6 is parallel to the length direction of the frame 2. The support strips 6 are generally made of aluminum alloy, which is lightweight and has sufficient strength. The support strips 6 can be strip-shaped plate structures, with a regular shape that facilitates manufacturing and installation. The sidewalls of the baking pan 11 slide in contact with the sidewalls of the two support strips 6, allowing the baking pan 11 to move along the support strips 6 during transport, ensuring stable transport of the baking pan 11. Alternatively, the support strips 6 can be made of plastic, such as polytetrafluoroethylene (PTFE), which has good self-lubricating properties and can reduce frictional resistance with the baking pan 11.

[0027] Reference Figure 2 , Figure 3 The adjustment component 7 includes a fixed base 71 fixed to the frame 2, a first slider 72 slidably connected to the fixed base 71 along the width direction of the frame 2, and a first limiting member 73 for limiting the sliding of the first slider 72. The fixed base 71 is fixedly connected to the frame 2. The first slider 72 is disposed on the lower surface of the support bar 6. The upper surface of the fixed base 71 is provided with a sliding groove 711 for the first slider 72 to slide. The length direction of the sliding groove 711 is parallel to the width direction of the fixed base 71. It should be noted that several first sliders 72 can be arranged at intervals along the length direction of the support bar 6 to improve the stability of the sliding.

[0028] The first limiting member 73 includes a lead screw 731 threaded through the first slider 72, a handwheel 732 fixedly connected to the end of the lead screw 731, and a guide rod 733 slidably passing through the first slider 72. One end of the lead screw 731 passes through the fixed seat 71 and extends into the slide groove 711, while the other end of the lead screw 731 is exposed. The handwheel 732 is located at the exposed end of the lead screw 731.

[0029] In this embodiment, the edges of the opposite sides of the baking tray 11 extend outward horizontally with abutment strips 111. The abutment strips 111 are integrally formed with the baking tray 11, which also makes it easier for the staff to hold the baking tray 11 and place it on the conveyor belt 3. The abutment strips 111 overlap the upper surface of the support strips 6, which further increases the stability of the baking tray 11 during the conveying process.

[0030] Furthermore, a ball bearing 61 is rotatably connected to the support strip 6. The ball bearing 61 can be disposed on the upper surface of the support strip 6 or on the side wall of the support strip 6, so as to abut against the lower edge of the abutment strip 111 and the side wall of the baking tray 11, respectively.

[0031] The implementation principle of the feeding and discharging conveying device for a vertical baking oven 1 in this application embodiment is as follows: the support mechanisms 5 on both sides of the frame 2 support the baking tray 11 during the conveying process, thereby reducing the shaking of the baking tray 11 during the conveying process and thus reducing the probability that the product in the baking tray 11 will be affected by shaking. This is because the support mechanism 5 restricts the two sides of the baking tray 11, making the baking tray 11 more stable during the conveying process.

[0032] Example 2: Reference Figure 4 , Figure 5 The difference from Embodiment 1 is that the adjustment assembly 7 includes a fixed base 71 fixedly connected to the frame 2, a rotating member 74 connected to the support bar 6 and rotatably connected to the fixed base 71, and a second limiting member 75 restricting the rotation of the support bar 6. The rotating member 74 specifically includes a rotating seat 741 fixedly connected to the lower surface of the support bar 6 and a rotating rod 742 fixedly passing through the rotating seat 741. The upper surface of the fixed base 71 has a mounting plate 712 protruding for the rotating rod 742 to be rotatably connected.

[0033] The second limiting member 75 includes a vertical rod 751 perpendicular to the axis of the rotating rod 742, a horizontal rod 752 parallel to the axis of the rotating rod 742, a limiting plate 753 through which the horizontal rod 752 passes, an elastic pad 754 coaxially sleeved on the horizontal rod 752, and a nut 755 threadedly connected to the horizontal rod 752. The horizontal rod 752 is a screw rod. The limiting plate 753 has a guide groove 8 extending through it along the direction of rotation of the horizontal rod 752 with the rotating rod 742. The horizontal rod 752 slides through the guide groove 8, and the elastic pad 754 is used to press against the limiting plate 753.

[0034] Furthermore, in this embodiment, the support strip 6 is arc-shaped, and its axis is positioned close to the rotating rod 742. Based on the dimensions of the baking pan 11, after rotating the support strip 6 to a certain angle, the nut 755 is rotated to press the elastic pad 754 against the limiting plate 753, thereby restricting the movement of the crossbar 752 along the guide groove 8, and consequently restricting the rotation of the support strip 6.

[0035] Example 3: Reference Figure 6 , Figure 7The difference from Embodiment 1 is that an elastic buffer layer 9 is provided on the side wall of the support strip 6 facing the baking pan 11. In this embodiment, the elastic buffer layer 9 includes several independent floating unit blocks 91. The support strip 6 has an installation groove 62. The floating unit block 91 includes a spring 911 built into the installation groove 62, a second slider 912 slidably inserted into the installation groove 62, and an abutment plate 913 provided on the second slider 912. The abutment plate 913 is an elastic pad 754. When the baking pan 11 squeezes the elastic block, the spring 911 is compressed to absorb the impact force. Then the spring 911 can return to its original shape, so that the elastic block always keeps in contact with the baking pan 11, which plays a better role in buffering and supporting.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
