Description

Technical Field

[0001] This utility model relates to the field of irradiation processing equipment technology, and in particular to an adjustable tray for irradiation processing. Background Technology

[0002] In the field of industrial irradiation processing, products to be processed are usually placed on special trays and transported to the irradiation source area for sterilization or modification through automated conveying devices. To ensure processing efficiency, the size of the trays is usually standardized. However, in actual production, the size and specifications of different batches of products to be processed often vary greatly.

[0003] Most current pallets adopt a one-piece molded fixed frame structure, or simply have fixed side panels around the perimeter. When processing smaller products, if such large fixed pallets are used directly, there will be a large gap between the product and the pallet side panels. During the high-speed operation, turning, or start-stop of the conveyor belt, the huge gap will cause the product to shake violently, shift, or even tip over inside the pallet. This will not only lead to uneven radiation dose received by the product, affecting processing quality, but in severe cases, it may also cause the product to tip over and get stuck on the conveyor line, causing the entire production line to stop. Although the gap can be reduced by filling with foam, this method is cumbersome and generates additional industrial waste. There is a lack of a pallet structure that can quickly and stably adjust the internal limit range according to the product size.

[0004] Therefore, this utility model proposes an adjustable tray for irradiation processing to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problem that the fixed size of the limiting structure of the irradiation processing tray in the prior art cannot be adapted to the stable loading of products of various specifications, which makes the products prone to shaking and displacement during the transportation process, thus affecting the processing quality or even causing the transportation failure, this utility model aims to provide an adjustable tray for irradiation processing with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an adjustable tray for irradiation processing, which mainly includes: an adjustment mechanism installed on a base bearing surface, a fixing mechanism for locking position, and a tray body as a base. The adjustment mechanism is installed on the tray body, and the fixing mechanism is disposed between the adjustment mechanism and the tray body. The three together constitute an adjustable bearing system.

[0007] Specifically, the adjustment mechanism includes an adjustable baffle, with sliders fixedly connected to both ends of the adjustable baffle. First grooves are correspondingly formed on the side walls of the tray body, and the sliders are slidably connected inside the first grooves. Through the cooperation of the sliders and grooves, the adjustable baffle can move along the tray body. The fixing mechanism includes an upper bushing, a lower bushing, a pin, a spring, a button, and a steel ball. The upper bushing is fixedly connected to the adjustable baffle, and the lower bushing is fixedly embedded in the bottom plate of the tray body. The upper and lower bushings are coaxially arranged vertically. The pin is slidably connected vertically through the interior of the upper and lower bushings. The button is fixedly connected to the top of the pin, and the spring is sleeved on the outer side wall of the pin located inside the upper bushing. To achieve the locking function, a receiving through hole is formed on the lower side wall of the pin. The steel ball is movably embedded in the receiving through hole, and a portion of the spherical surface of the steel ball protrudes from the outer surface of the pin to form a snap-fit ​​engagement with the lower bushing.

[0008] Preferably, in order to compensate for the slight error between the adjustment mechanism and the fixed point, a second sliding groove is provided on the bottom plate of the adjustable baffle, the upper bushing passes through the inside of the second sliding groove, and the outer wall of the upper bushing and the inner wall of the second sliding groove are slidably connected to each other, so that the upper bushing can be finely adjusted in a small range to align with the fixing hole below.

[0009] Preferably, in order to enhance the overall strength and impact resistance of the baffle structure, the adjustment mechanism further includes two reinforcing ribs, which are fixedly connected to the angle between the vertical and horizontal surfaces of the adjustable baffle to form a stable triangular support structure.

[0010] Preferably, regarding the specific reset structure inside the fixing mechanism, the upper bushing has a cylindrical cavity inside, the bottom surface of the upper bushing has an annular step, the top end of the spring abuts against the bottom end face of the button, and the bottom end of the spring abuts against the top surface of the annular step, using the spring force to drive the pin upward to reset and maintain the locked state.

[0011] Preferably, in order to achieve automatic retraction and release of the steel ball, the lower part of the pin is provided with a necking groove. The diameter of the necking groove is smaller than the diameter of the pin body. When the pin moves downward, the steel ball can retract inward and be contained in the necking groove, thereby eliminating mechanical interference to the lower bushing.

[0012] Preferably, in order to improve the connection reliability in the locked state, the inner sidewall of the lower bushing is provided with an annular locking groove along the circumferential direction. The cross-sectional shape of the annular locking groove is adapted to the spherical shape of the steel ball. The steel ball is inserted into the annular locking groove to achieve rigid locking of the adjustable baffle.

[0013] Preferably, in order to accommodate workpieces of different lengths and achieve graded adjustment, the bottom plate of the pallet body is provided with a number of installation blind holes at equal intervals along the length direction of the first slide groove. The lower bushing is fixedly installed inside each of the installation blind holes, thereby providing multiple preset locking positions.

[0014] Preferably, to facilitate the insertion of the pin, the bottom end of the pin is machined with a chamfered guide surface, which is shaped like a frustum of a cone, and is used to guide the pin to be accurately inserted into the interior of the lower bushing during the downward movement of the pin.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing irradiation processing pallets have fixed limiting space and cannot be flexibly adjusted according to the size of different batches of workpieces, which makes the workpieces easy to shake or tip over during the transmission process. By setting sliding grooves on both sides of the pallet body and adjustable baffles that slide in cooperation with the sliding grooves, it achieves the technical effect of enabling stepless or graded adjustment of the internal placement space of the pallet, ensuring that the workpieces are tightly limited, thereby improving the transmission stability and safety during the irradiation processing.

[0016] 2. This utility model, by setting a fixing mechanism including a pin, spring, steel ball and bushing, uses a button to drive the pin to move and control the radial extension and retraction of the steel ball to lock into or out of the lower bushing. This solves the problem of cumbersome or unreliable fixing methods after traditional pallet adjustment. It achieves quick locking and releasing of the baffle without the need for additional tools, significantly improving the efficiency of loading, unloading and adjustment operations. Moreover, the surface contact between the steel ball and the annular groove has a strong anti-vibration performance.

[0017] 3. This utility model solves the problem that when the adjustable baffle moves to a specific position, the locking mechanism on it may not be precisely coaxially aligned with the preset fixing hole on the bottom of the tray. By opening a second sliding groove at the bottom of the adjustable baffle and allowing the upper bushing to slide and make fine adjustments therein, it achieves the technical effect of compensating for position deviation, realizing automatic alignment between the adjustment mechanism and the fixing hole, ensuring that the pin can be smoothly inserted into the nearest locking point, reducing the difficulty of operation and improving the adjustment accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 This utility model provides an adjustable tray for irradiation processing, which aims to solve the problem that the existing tray limiting structure is simple and cannot be flexibly adjusted according to the size of the workpiece, which makes the workpiece prone to displacement or tipping during irradiation transmission.

[0022] like Figure 1 and Figure 2 As shown, the overall structure of the adjustable tray for irradiation processing mainly includes an adjustment mechanism 1, a fixing mechanism 2, and a tray body 3. The tray body 3 serves as the basic load-bearing component of the entire device, and its top surface is a plane for placing the product to be processed. The adjustment mechanism 1 is installed above the tray body 3 to limit and surround the product. The fixing mechanism 2 is located at the connection between the adjustment mechanism 1 and the tray body 3 to lock the adjusted mechanism in a specific position.

[0023] The adjustment mechanism 1 specifically includes an adjustable baffle 101, with sliders 103 fixedly connected to both ends of the adjustable baffle 101. Correspondingly, first grooves 102 are provided on the vertical walls on both sides of the tray body 3. The sliders 103 are slidably connected to the inside of the first grooves 102. The outer dimensions of the sliders 103 and the inner wall dimensions of the first grooves 102 are fitted with clearance or transition to ensure smooth sliding and reduce play. By sliding the sliders 103 along the length of the first grooves 102, the adjustable baffle 101 can be adjusted in the front and back position on the tray body 3.

[0024] To further enhance the structural rigidity of the device and prevent deformation of the baffle due to inertial impact during irradiation transmission, a reinforcing rib 105 is fixedly connected at the angle between the inner sidewall of the adjustable baffle 101 and the horizontal base plate. The reinforcing rib 105 has a right-angled triangular plate structure, and its two right-angled sides are fixedly connected to the vertical plate surface and the horizontal plate surface of the adjustable baffle 101 by welding, respectively. Preferably, there are two reinforcing ribs 105, which are symmetrically distributed along the length of the adjustable baffle 101. This triangular support structure can effectively disperse stress.

[0025] In the connection and cooperation between the adjustment mechanism 1 and the fixing mechanism 2, a second slide groove 104 is also provided on the horizontal base plate of the adjustable baffle 101. The upper bushing 201 in the fixing mechanism 2 passes through the interior of the second slide groove 104, and the outer cylindrical surface of the upper bushing 201 is slidably connected to the inner side wall of the second slide groove 104. The upper bushing 201 can be finely adjusted and moved in the second slide groove 104 in a direction perpendicular to or parallel to the first slide groove 102. This cooperation relationship ensures that even if there is a slight deviation between the fixing hole at the bottom of the tray body 3 and the current position of the adjustable baffle 101, the operator can compensate for the error by moving the upper bushing 201, thereby successfully achieving the centering connection between the pin 203 and the structure below.

[0026] The fixing mechanism 2 is composed of an upper bushing 201, a lower bushing 202, a pin 203, a spring 204, a button 205, and a steel ball 206. The upper bushing 201 has a cylindrical cavity, and the inner wall of the bottom of the cavity extends inward to form an annular step. The spring 204 is housed in the internal space of the upper bushing 201, with its bottom end abutting against the top surface of the annular step and its top end abutting against the bottom end face of the button 205. The button 205 is fixedly connected to the top of the pin 203 as the force point for manual operation.

[0027] The pin 203, acting as an actuator, passes vertically through and slides within the internal cavities of the upper bushing 201 and the lower bushing 202. The lower side wall of the pin 203 has a receiving through hole, in which the steel ball 206 is movably embedded. To achieve the automatic retraction and unlocking function of the steel ball 206, the pin 203 has a necking groove or a variable diameter structure inside or on its rod. This structure allows the steel ball 206 to retract inward at a specific position. The lower bushing 202 is fixedly embedded in the bottom plate of the tray body 3. Its inner side wall has an annular locking groove along the circumferential direction. The cross-sectional shape of the groove is machined to be a semi-circle or arc shape that matches the spherical curvature of the steel ball 206.

[0028] As a preferred embodiment, in order to meet the multi-level adjustment requirements of workpieces of different sizes, the bottom plate of the tray body 3 is provided with a number of installation blind holes at equal intervals along the length direction of the first slide groove 102. Each installation blind hole is fixedly installed with a lower bushing 202 by interference fit. These lower bushings 202 form a row of preset locking points on the bottom surface of the tray. In addition, in order to facilitate the smooth insertion of the pin 203 into the lower bushing 202, the bottom end of the pin 203 is machined with a chamfered guide surface in the shape of a frustum cone to correct minor coaxiality deviations.

[0029] The working principle of this adjustable tray for irradiation processing is as follows: When the tray is used for irradiation processing, the operator first adjusts the position of the adjustable baffle 101 according to the size of the workpiece to be processed, and manually pushes the adjustable baffle 101 so that the sliders 103 at both ends slide smoothly along the first groove 102 on the side wall of the tray body 3 until the adjustable baffle 101 moves to a position that can abut against the workpiece or leave a suitable space.

[0030] After the initial position is determined, the nearest lower bushing 202 on the bottom plate of the tray body 3 is selected as the locking point. If the pin 203 is not accurately aligned with the lower bushing 202 at this time, the operator can finely adjust the position of the upper bushing 201 in the second slide groove 104 to make it coaxially aligned with the lower bushing 202. Then, the operator presses down the button 205. The button 205 drives the pin 203 to move downward and compress the spring 204. As the pin 203 moves downward, the constriction groove on the pin 203 moves to a position that allows the steel ball 206 to retract. The steel ball 206 retracts inward under the pressure of the hole wall, so that the pin 203 can be inserted into the lower bushing 202 without obstruction.

[0031] When the pin 203 is fully inserted and the operator releases the button 205, the spring 204 releases its elastic potential energy, pushing the button 205 and the pin 203 upwards to reset. During the upward reset of the pin 203, its thicker rod section pushes the steel ball 206 radially outwards again, forcing part of the spherical surface of the steel ball 206 to be tightly locked into the annular locking groove on the inner wall of the lower bushing 202. At this time, the upper bushing 201 and the lower bushing 202 are rigidly connected, and the adjustable baffle 101 is firmly locked on the tray body 3. Finally, the workpiece is placed in the tray and pressed against the locked adjustable baffle 101, and the irradiation process can begin. After the processing is completed, if it is necessary to remove the workpiece or change the specifications, press the button 205 again to retract the steel ball 206 to unlock, pull out the pin 203 and slide the adjustable baffle 101 to reset.
