Description

Novel anchor clamps for pineapple processing

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to a clamp for peeling a pineapple through core, and specifically relates to a novel clamp for applying the pineapple to the operation of peeling the pineapple through core.

Background

The pineapple yield and the pineapple demand are huge every year in China, but the insufficient processing capacity of the pineapples becomes an important factor for restricting the development of the pineapple economic industry in China. Meanwhile, the technology of peeling the pineapple without passing through the core is not mature enough, and the link of peeling the pineapple without passing through the core is an important link in the pineapple processing industry and the development of pineapple products. The pineapple core-through peeling work is difficult, but the pineapple core-through peeling work is an indispensable link for obtaining pineapple products, and the pineapple clamp is indispensable for ensuring the smooth completion of the core-through peeling operation. At present, no specific pineapple clamp is provided, generally, pineapples are placed in a fixed cylinder, and peeling and core passing are carried out by punching through a cylindrical cutter. The rotary peeling and core passing is basically finished by peeling firstly and then passing through the core in two steps, the pineapple is generally clamped by a chuck ejector pin during peeling, so that the core is required to be arranged, peeling and core passing operations cannot be finished simultaneously, the core passing after peeling also needs to be replaced by a clamp for positioning, the operation is complicated, the efficiency is low, and the requirement of large-batch processing is not met.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects of the existing pineapple clamp in the core-through peeling technology, and provides a pineapple clamp for the core-through peeling process of a pineapple, so as to ensure that the pineapple is over-positioned before the core-through operation, thereby ensuring that the core of the pineapple and a cutter for core-through are approximately in the same axis, and preventing the pineapple from being wasted due to cutting off excessive pulp in the core-through process. The pineapple clamping and positioning mechanism is compact in structure, simple and easy to operate, can clamp and position pineapples while protecting pineapple pulp, and solves the technical problems that the pineapple core is wasted much, the pulp is damaged greatly and the like at present.

In order to solve the technical problems, the utility model adopts the following technical scheme: v-shaped block positioning device and double V-shaped block eccentric wheel clamping device.

The clamp is integrally fixed on the support, the positioning device is mainly used for positioning the common V-shaped blocks, the pineapple material falls into the arc-shaped groove in a certain posture, and then the center of the two V-shaped blocks, namely the center of the pineapple material, is ensured to be on the same axis with the cutter of the core penetrating cutter through the cooperation of the other V-shaped block which is moved at the same distance with the clamp, so that the positioning is realized. The positioning device is connected with the sliding rod with the spring, and the positioning is realized by realizing the equidistant movement matched with each other through the driving of the clamping device driven by the motor. The clamping device is driven by a motor, and the whole power system mainly comprises the motor, a speed reducer, a transmission shaft, an eccentric wheel, a spring, a sleeve and the like. The clamping force is formed by the displacement of the spring, and the clamping force formed by the spring can have a little variable space, so that the problems of clamping the pineapple and the like cannot occur.

The two V-shaped blocks are symmetrically arranged at two ends of the arc-shaped groove, the spring and the rod connected with the two V-shaped blocks are positioned on the same axis, and the two V-shaped blocks are hinged on the same sleeve rod through two connecting rods. The sleeve rod is also connected with a spring, and the upper and lower displacements of the sleeve rod can realize the opening and closing of the two V-shaped blocks. The power mechanism is positioned at the lower rear part of the whole device, and the output of the motor drives the connecting rod mechanism to move through the speed reducer and the eccentric wheel.

The bracket is provided with an arc-shaped groove for placing pineapple materials.

The springs are not simply placed, one end of each spring is fixed with the corresponding sleeve, the other end of each spring is fixed with the corresponding base body, and the sleeves are influenced by the springs when moving on the base bodies.

The parameters of the V-shaped block and the spring are used for a certain size of pineapple, namely after grading of the pineapple.

The rotating speed of the motor of the power device after passing through the speed reducer can ensure that one circle of eccentric wheel rotates to just finish one clamping process.

The rotation center of the eccentric wheel mechanism is coincided with the axis of the movement of the middle sleeve.

The spring is in a compressed state at an initial position and the clamp is in a clamped state.

The movement of the eccentric mechanism essentially effects the opening of the clamp, i.e. the eccentric does not play a significant role in the tensioning of the clamp during the return movement.

According to the utility model, when the pineapple is clamped, the eccentric wheel and the connecting rod mechanism drive the spring to displace and transfer force, so that the opening and closing of the two V-shaped blocks in the clamp are realized, and the force generated during clamping is not generated by an external power device and is provided by the spring. Not only ensures that the pineapple cannot be damaged due to overlarge clamping force, but also can realize that the pineapple in the clamp is pushed into the core-through peeling tool by the push rod to complete the required working procedure. The whole clamp device is simple in structure and compact in structure, is not only suitable for clamping pineapples, but also can be used for clamping other easily-damaged columnar articles.

Starting the machine, driving the eccentric wheel 3 to do circular motion under the action of the motor 1 and the speed reducer 2, keeping the eccentric wheel 3 in contact with the push rod 4, when the eccentric wheel 3 is at the bottom end, the push rod 4 is also at the bottom end, and at the moment, the push rod spring 5 in the push rod 4 is in an initial compression state, and the clamp body is clamped. After the eccentric wheel 3 rotates, the push rod 4 is pushed upwards, so that the push rod spring 5 is continuously compressed to move upwards, one end of the connecting rod 6(7) is hinged to the push rod 4, the other end of the connecting rod 6(7) is hinged to the sliding rod 8(9) to do plane motion under the driving of the push rod, due to the structural symmetry, the plane motion of the connecting rod 6(7) is also symmetrical, so that the sliding rod 8(9) is driven to do reverse direction sliding at equal intervals, the sliding rod spring 10 is compressed, the two V-shaped blocks 11 are separated, and the clamp is opened. After the pineapple materials fall into the corresponding position of the arc-shaped groove 12, the eccentric wheel 3 continues to rotate to enable the push rod 4 to enter a return stroke, the springs 5 and 10 in the compressed state can be unloaded in the process, the two V-shaped blocks 11 are folded simultaneously to clamp the pineapple materials, when the push rod 4 returns to the bottom end, the three springs return to the initial compressed state, the two V-shaped blocks 11 are closest to each other, the pineapple is clamped to the tightest, and the positioning operation of the pineapple core and the axis of the cutter is completed. The process is from the opening of the clamp to the clamping of the clamp to complete the whole working process and working principle of the core-through positioning. After the clamp finishes the clamping and positioning processes, the motor 1 stops working, the pineapples are clamped by the force of a spring arranged in the clamp, then the pineapples are pushed into the rotary core-through peeling cutter by another push rod to carry out core-through peeling operation, after the core-through peeling operation is finished, the motor 1 starts to operate again, and the processes are repeated to finish the positioning and clamping of the pineapple materials at the next time. The clamp is simple and compact in design structure, the pineapple cannot be damaged due to the fact that the pineapple is clamped too tightly by the elastic clamp, the pineapple cannot be pushed by the push rod to affect the peeling operation of the through core, the shaft core of the pineapple cannot be accurately positioned with the axis of the through core peeling cutter, the waste of the through core is avoided, and the requirement for clamping and processing the pineapple in the market can be met.

The clamp is a pineapple clamp which is suitable for elastic clamping and is used for completing two operations of core passing and peeling in one step. The center of the hand part of the clamp is coincided with the axis of the through core peeling cutter, and after clamping and positioning are completed, the pineapple is pushed into the cutter from the clamp to complete corresponding operation.
