Description

Technical Field

[0001] The utility model relates to the technical field of surface processing equipment, in particular to a baking tray processing device. Background Art

[0002] In cooking appliances such as ovens and deep fryers, most use baking trays to hold the food to be cooked. During the entire cooking process, the temperature of the entire oven can reach 200°C to 230°C. Especially when cooking some frozen foods, the baking tray is prone to deformation due to the thermal shock.

[0003] Currently, the common methods to solve the deformation of the baking tray in the market are: (1) increasing the strength of the baking tray by adding a certain shape to the baking tray; (2) increasing the strength of the baking tray by increasing the material thickness of the baking tray so as to reduce the deformation of the baking tray.

[0004] Although the former increases the strength of the baking tray to a certain extent, it will still deform above 200°C. In addition, excessive shaping (depth > 3mm) of the baking tray will affect the cooking uniformity and the overall volume of the baking tray; while the latter will increase the overall cost of the machine and affect the heat absorption at the bottom of the food, resulting in uneven cooking of the whole food. Summary of the Utility Model

[0005] Based on this, in view of the problem that the current baking tray is prone to deformation under thermal shock, and common methods such as shaping and thickening all have certain defects, it is necessary to provide a baking tray processing device that can solve the above problems.

[0006] This application first provides a baking tray processing device, including a support frame, a reciprocating drive structure, a clamping structure, and an ultrasonic shot peening structure.

[0007] The clamping structure is arranged on the moving end of the reciprocating drive structure, and the clamping structure is used to clamp the baking tray; the reciprocating drive structure is arranged on the support frame and can drive the clamping structure to move reciprocally; the ultrasonic shot peening structure is relatively fixed to the support frame and is located at the bottom of the baking tray.

[0008] In one embodiment, the clamping structure includes a support plate and a clamping component arranged on the support plate. The support plate is fixed to the moving end of the reciprocating drive structure and is provided with an installation hole corresponding to the baking tray that penetrates in the vertical direction.

[0009] A limiting member surrounding the installation hole is further fixed on the top surface of the support plate. There is a gap between the inner wall of the limiting member and the inner wall of the installation hole to form a step surface for supporting the edge of the baking tray between the two.

[0010] The clamping component is used to cooperate with the step surface to clamp the baking tray.

[0011] In one embodiment, the baking tray abuts against the inner wall of the limiting member in its own width direction, and there is a gap between the baking tray and the inner wall of the limiting member in its own length direction.

[0012] In one embodiment, the clamping assembly includes a locking frame, a locking pressing block and a locking screw. The locking frame is fixed on the top surface of the support plate. The locking pressing block penetrates through the locking frame and the limiting member in the horizontal direction to clamp the edge of the baking tray in cooperation with the step surface. The locking screw is threadedly connected to the top of the locking frame and is used to squeeze the locking pressing block in the vertical direction.

[0013] In one embodiment, two sets of the clamping assemblies are arranged on the support plate, and the two sets of the clamping assemblies are respectively located on both sides of the mounting hole along the length direction of the mounting hole.

[0014] In one embodiment, the reciprocating driving structure includes a motor, a pulley set and a fixed slider. The motor and the pulley set are both arranged on the support frame. The fixed slider is fixed to the belt of the pulley set. The motor is power-connected to the pulley set to drive the fixed slider to move, and the clamping structure is fixed to the fixed slider.

[0015] In one embodiment, the reciprocating driving structure further includes a slide rail. The slide rail is fixed to the support frame and is parallel to the moving direction of the fixed slider. The clamping structure has a sliding groove slidably connected to the slide rail.

[0016] In one embodiment, two slide rails are symmetrically fixed on the support frame, and two sliding grooves are correspondingly formed on the clamping structure.

[0017] In one embodiment, the ultrasonic shot peening structure includes a tool head, a horn, a transducer and a power supply. Among them, the tool head, the horn and the transducer are fixed in sequence from top to bottom. The tool head is used to accommodate pellets and abuts against the bottom surface of the baking tray.

[0018] The transducer and the power supply are both fixed relative to the support frame, and are electrically connected through a power cord.

[0019] In one embodiment, the tool head is flush with both sides of the baking tray in the width direction of the baking tray.

[0020] The above baking tray processing equipment, after clamping and fixing the baking tray through the clamping structure, drives the baking tray to move reciprocally through the reciprocating driving structure, and cooperates with the ultrasonic shot peening structure at the bottom to perform surface treatment on the baking tray. Residual compressive stress is implanted into the near-surface layer of the baking tray through ultrasonic shot peening strengthening treatment, thereby improving the strength of the near-surface layer of the material, enhancing the anti-deformation and anti-corrosion capabilities of the baking tray, and further achieving the effects of extending the service life of the baking tray, reducing the thickness of the baking tray material, and reducing the overall cost of the equipment. It can also avoid affecting the cooking effect due to the excessive thickness of the baking tray material. Brief Description of the Drawings

[0026] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0028] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0029] In the present utility model, unless otherwise clearly specified and defined, the terms "mounted", "connected", "connected to", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0032] Please refer to Figure 1 and Figure 2 As shown, the present application first provides a baking tray processing device, including a support frame 10, a reciprocating driving structure 20, a clamping structure 30 and an ultrasonic shot peening structure 40. The clamping structure 30 is disposed on the moving end of the reciprocating driving structure 20, and the clamping structure 30 is used to clamp the baking tray 1; the reciprocating driving structure 20 is disposed on the support frame 10 and can drive the clamping structure 30 to reciprocate; the ultrasonic shot peening structure 40 is relatively fixed to the support frame 10 and is located at the bottom of the baking tray 1.

[0033] In the present application, after the baking tray 1 is clamped and fixed by the clamping structure 30, the reciprocating driving structure 20 drives the baking tray 1 to reciprocate, and cooperates with the ultrasonic shot peening structure 40 at the bottom to perform surface treatment on the baking tray 1. Residual compressive stress is implanted into the near-surface layer of the baking tray 1 through ultrasonic shot peening strengthening treatment, thereby improving the strength of the near-surface layer of the material, improving the anti-deformation and anti-corrosion capabilities of the baking tray 1, and further achieving the effects of extending the service life of the baking tray 1, reducing the material thickness of the baking tray 1 and reducing the overall cost of the equipment, and can also avoid affecting the cooking effect due to the excessive thickness of the baking tray 1.

[0034] Specifically, the ultrasonic shot peening structure 40 can cause plastic deformation on the surface of the baking tray 1 by repeatedly impacting the surface of the baking tray 1 with high-speed pellets, forming a hardened layer with a certain thickness. This hardened layer has high hardness and large residual compressive stress, which can significantly improve the fatigue, anti-deformation and anti-corrosion capabilities of the material.

[0035] More specifically, driving the baking tray 1 to reciprocate by the reciprocating driving structure 20 can achieve the strengthening treatment of the entire surface of the baking tray 1; and locking the baking tray 1 by the clamping structure 30 can prevent the baking tray 1 from shaking due to the impact of the pellets during the shot peening surface treatment, thereby avoiding the occurrence of uneven overall surface treatment.

[0036] Of course, in some other embodiments, in addition to the baking tray 1, the present application can also process other parts that require anti-deformation and anti-corrosion capabilities, such as the inner liner of some cooking equipment, etc. The present application will not list them one by one here.

[0037] Please refer to Figure 1 and Figure 2As shown, in some embodiments, the clamping structure 30 includes a support plate 31 and a clamping assembly 32 disposed on the support plate 31. The support plate 31 is fixed to the moving end of the reciprocating driving structure 20 and is provided with an installation hole 311 corresponding to the baking tray 1 that penetrates in the vertical direction. A limiting member 312 surrounding the installation hole 311 is further fixed on the top surface of the support plate 31. There is a gap between the inner wall of the limiting member 312 and the inner wall of the installation hole 311 to form a stepped surface 313 for supporting the edge of the baking tray 1 therebetween. The clamping assembly 32 is used to cooperate with the stepped surface 313 to clamp the baking tray 1.

[0038] After clamping and fixing the baking tray 1 through the stepped surface 313 and the clamping assembly 32, ultrasonic shot peening treatment can be performed on the baking tray 1. The baking tray 1 can be placed with the front side facing up or the back side facing up, and surface treatment can be performed on both the front and back sides of the baking tray 1.

[0039] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the baking tray 1 abuts against the inner wall of the limiting member 312 in its own width direction, and there is a gap between the baking tray 1 and the inner wall of the limiting member 312 in its own length direction.

[0040] Among them, the abutment in the width direction is used to play a role of limiting and positioning through the limiting member 312, avoiding the baking tray 1 from shaking in the width direction during the ultrasonic shot peening treatment, and also facilitating the operator to install the baking tray 1 to the correct processing position.

[0041] And the gap in the length direction facilitates taking out the baking tray 1 from the limiting member 312 after processing is completed.

[0042] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the clamping assembly 32 includes a locking frame 321, a locking pressure block 322, and a locking screw 323. The locking frame 321 is fixed to the top surface of the support plate 31. The locking pressure block 322 penetrates through the locking frame 321 and the limiting member 312 in the horizontal direction to cooperate with the stepped surface 313 to clamp the edge of the baking tray 1. The locking screw 323 is threadedly connected to the top of the locking frame 321 and is used to squeeze the locking pressure block 322 in the vertical direction.

[0043] Of course, in some other embodiments, other common structures can also be used to clamp the baking tray 1, as long as it can be clamped and relaxed as needed. Examples are not given one by one in this application.

[0044] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, two groups of clamping assemblies 32 are provided on the support plate 31, and the two groups of clamping assemblies 32 are respectively located on both sides of the installation hole 311 along the length direction of the installation hole 311 to improve the clamping firmness and sandwich stability of the clamping structure 30 for the baking tray 1.

[0045] Of course, in some other embodiments, the number and position of the clamping assembly 32 can also be adjusted according to actual needs, as long as it can ensure that the baking tray 1 is firmly clamped.

[0046] Please refer to Figure 1 and Figure 3 As shown, in some embodiments, the reciprocating drive structure 20 includes a motor 21, a pulley group 22, and a fixed slider 23. The motor 21 and the pulley group 22 are both arranged on the support frame 10. The fixed slider 23 is fixed to the belt of the pulley group 22. The motor 21 is power-connected to the pulley group 22 to drive the fixed slider 23 to move, and the clamping structure 30 is fixed to the fixed slider 23.

[0047] By the forward and reverse rotation of the motor, the reciprocating movement of the fixed slider 23 can be realized, thereby driving the clamping structure 30 and the baking tray 1 to achieve reciprocating movement, and then completing the surface treatment of the entire baking tray 1. At the same time, the belt drive has the characteristic of stable transmission compared with other transmission methods, which can improve the uniformity of shot peening treatment.

[0048] Specifically, the fixed slider 23 is fixed to the support plate 31 by screws.

[0049] Of course, in some other embodiments, other common transmission methods such as a sprocket group and a lead screw nut structure can also be used, as long as the reciprocating movement can be realized relatively stably, and the present application will not list them one by one here.

[0050] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the reciprocating drive structure 20 further includes a slide rail 24. The slide rail 24 is fixed to the support frame 10 and is parallel to the moving direction of the fixed slider 23. The clamping structure 30 has a sliding groove 33 slidably connected to the slide rail 24.

[0051] The cooperation of the sliding groove 33 and the slide rail 24 can improve the moving stability, prevent the clamping structure 30 and the baking tray 1 from shaking during the reciprocating movement, and thus improve the uniformity of the shot peening treatment of the baking tray 1.

[0052] Preferably, two slide rails 24 are symmetrically fixed on the support frame 10, and two sliding grooves 33 are correspondingly formed on the clamping structure 30.

[0053] Please refer to Figure 1 and Figure 4 As shown, in some embodiments, the ultrasonic shot peening structure 40 includes a tool head 41, a horn 42, a transducer 43, and a power supply 44. Among them, the tool head 41, the horn 42, and the transducer 43 are fixed in sequence from top to bottom. The tool head 41 is used to accommodate pellets and abuts against the bottom surface of the baking tray 1;

[0054] Both the transducer 43 and the power supply 44 are fixed relative to the support frame 10, and they are electrically connected through a power cord.

[0055] Among them, the transducer 43 is used to convert an electrical signal into a mechanical vibration signal, the horn 42 is used to amplify the mechanical vibration signal and then transmit it to the tool head 41, and the vibration of the tool head 41 drives the pellets to move up and down in height to impact the baking tray 1, thereby completing the surface treatment of the baking tray 1.

[0056] Please refer to Figure 1 and Figure 4 As shown, in some embodiments, the tool head 41 is flush with both sides of the baking tray 1 along the width direction of the baking tray 1, and only by driving the baking tray 1 to reciprocate along the length direction can the ultrasonic shot peening treatment of the entire surface of the baking tray 1 be realized.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0058] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
